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 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;

• the costs and effects of legal and administrative proceedings;

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

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 and results of operations 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, 2017 was derived from our audited consolidated financial statements for the fiscal year ended March 31, 2017 included in our Annual Report on Form 10-K (“Annual Report”) filed with the SEC on May 26, 2017.

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, 2018.

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 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, and accruals for environmental matters. 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

NGL ENERGY PARTNERS LP AND SUBSIDIARIES

Notes to Unaudited Condensed Consolidated Financial Statements (Continued)

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 risk policy, respectively.Open commodity positions and market price changes are monitored daily and are reported to senior management and to marketing operations personnel.Credit risk is monitored daily and exposure is minimized through customer deposits, restrictions on product liftings, letters of credit, and entering into master netting agreements that allow for offsetting counterparty receivable and payable balances for certain transactions.

Revenue Recognition

We record product sales revenues when title to the product transfers to the purchaser, which typically occurs when the purchaser receives the product. We record terminaling, transportation, storage, and service revenues when the service is performed, and we record tank and other rental revenues over the lease term. Revenues for our Water Solutions segment are recognized when we obtain the wastewater at our treatment and disposal facilities.

The tariffs we charge for our pipeline transportation systems are primarily regulated by the Federal Energy Regulatory Commission. Our tariffs include provisions which allow us to deduct from our customer’s inventory a small percentage of the products our customers transport on our pipeline systems. We refer to these product quantities as pipeline loss allowance. We receive pipeline loss allowances from our customers as consideration for product losses during the transportation of their products on our pipeline systems. Our customers are guaranteed delivery of the amount of their injected volumes, net of pipeline loss allowance, irrespective of what our actual product losses may be during the delivery process.

We report taxes collected from customers and remitted to taxing authorities, such as sales and use taxes, on a net basis. We include amounts billed to customers for shipping and handling costs in revenues in our unaudited condensed consolidated statements of operations. We enter into certain contracts whereby we agree to purchase product from a counterparty and sell the same volume of product to the same counterparty at a different location or time. When such agreements are entered into at the same time and in contemplation of each other, we record the revenues for these transactions net of cost of sales.

Revenues during the three months endedSeptember 30, 2017 and 2016 include $0.3 million and $1.2 million, respectively, and revenues during the six months endedSeptember 30, 2017 and 2016 include $0.7 million and $2.5 million, respectively, associated with the amortization of a liability recorded in the acquisition accounting for an acquired business related to certain out-of-market revenue contracts.

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 the United States and 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 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

NGL ENERGY PARTNERS LP AND SUBSIDIARIES

Notes to Unaudited Condensed Consolidated Financial Statements (Continued)

position that meets the more likely than not threshold is measured to determine the amount of benefit to be recognized in the consolidated financial statements. We had no material uncertain tax positions that required recognition in our unaudited condensed consolidated financial statements at September 30, 2017 or March 31, 2017.

Inventories

We value our inventories at the lower of cost or market, with cost determined using either the weighted-average cost or the first in, first out (FIFO) methods, including the cost of transportation and storage. Market is determined based on estimated replacement cost using prices at the end of the reporting period. On April 1, 2017, we adopted the new inventory standard, Accounting Standards Update (“ASU”) No. 2015-11. Under this ASU, inventory is to be measured at the lower of cost or net realizable value, which is defined as the estimated selling price in the ordinary course of business, less reasonable predictable costs of completion, disposal, and transportation. In performing this analysis, we consider fixed-price forward commitments and the opportunity to transfer propane inventory from our wholesale Liquids business to our Retail Propane business to sell the inventory in retail markets.

Inventories consist of the following at the dates indicated:

	September 30, 2017		March 31, 2017
	(in thousands)
Crude oil	$	81,969	$	146,857

Other	8,628		9,210
Total	$	570,733	$	561,432

Investments in Unconsolidated Entities

Investments we cannot 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 historical net book value of the net assets of the investee. We use the cumulative earnings approach to classify distributions received from unconsolidated entities as either operating activities or investing activities in our unaudited condensed consolidated statements of cash flows.

(2) Represents minimum volumes of crude oil we are required to leave on certain third-party owned pipelines under long-term shipment commitments. At September 30, 2017 and March 31, 2017, line fill consisted of 427,193 barrels and 427,193 barrels of crude oil, respectively. 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 September 30, 2017 and March 31, 2017, tank bottoms held in third party terminals consisted of 366,212 barrels and 366,212 barrels of refined products, respectively. Tank bottoms held in terminals we own are included within property, plant and equipment (see Note 5).

(4) Represents the minimum shipping fees paid in excess of volumes shipped for two contracts. This amount can be recovered when volumes shipped exceed the minimum monthly volume commitment (see Note 9). Under these contracts, we currently have 2.6 years and 3.0 years, respectively, in which to ship the excess volumes.

Accrued Expenses and Other Payables

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

	September 30, 2017		March 31, 2017
	(in thousands)
Accrued compensation and benefits	$	23,083	$	22,227

Other	20,584		17,001
Total	$	227,069	$	207,125

Deferred Gain on Sale of General Partner Interest in TLP

On February 1, 2016, we sold our general partner interest in TransMontaigne Partners L.P. (“TLP”) to an affiliate of ArcLight Capital Partners. We deferred a portion of the gain on the sale and will recognize this amount over our future lease payment obligations, which is approximately seven years. During the three months endedSeptember 30, 2017 and 2016, we recognized $7.5 million and $7.5 million, respectively, and during the six months endedSeptember 30, 2017 and 2016, we recognized $15.1 million and $15.1 million, respectively, of the deferred gain in our unaudited condensed consolidated statements of operations. Within our September 30, 2017 unaudited condensed consolidated balance sheet, the current portion of the deferred gain, $30.1 million, is recorded in accrued expenses and other payables, and the long-term portion, $124.2 million, is recorded in other noncurrent liabilities.

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. During the six months endedSeptember 30, 2017, we recorded $0.7 million to adjust the redeemable noncontrolling interest to its maximum redemption value.

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 six months endedSeptember 30, 2017 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, 2017.

Reclassifications

We have reclassified certain prior period financial statement information to be consistent with the classification methods used in the current fiscal year. These reclassifications did not impact previously reported amounts of equity, net income, or cash flows. Also, certain line items in our unaudited condensed consolidated statement of cash flows were combined and the prior period amounts were combined to be consistent with the classification methods used in the current fiscal year.

Recent Accounting Pronouncements

In August 2016, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2016-15, “Statement of Cash Flows-Classification of Certain Cash Receipts and Cash Payments.” The ASU requires cash payments not made soon after the acquisition date of a business combination by an acquirer to settle a contingent consideration liability to be separated and classified as cash outflows for financing activities and operating activities. Cash payments up to the amount of the contingent consideration liability recognized at the acquisition date (including measurement-period adjustments) should be classified as financing activities and any excess should be classified as operating activities. We adopted this ASU effective April 1, 2017 and have revised previously reported information.

In June 2016, the FASB issued ASU No. 2016-13, “Financial Instruments-Credit Losses.” The ASU requires a financial asset (or a group of 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.

In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers.” The ASU will replace most existing revenue recognition guidance in GAAP. The core principle of this ASU is that an entity should recognize revenue for the transfer of goods or services equal to the amount that it expects to be entitled to receive for those goods or services. The ASU is effective for the Partnership beginning April 1, 2018, and allows for both full retrospective and modified retrospective methods of adoption.

We are in the process of evaluating our revenue contracts by segment and type to determine the potential impact of adopting this ASU. At this point in our evaluation process, we have determined that the timing and/or amount of revenue that we recognize on certain contracts, particularly contracts with minimum volume commitments, tiered pricing, non-cash consideration and multi-year services arrangements, may be impacted by the adoption of this ASU; however, we are still in the process of quantifying these impacts and have not yet determined whether they would be material to our consolidated financial statements. In addition, we are in the process of implementing appropriate changes to our business processes, systems and controls to support recognition and disclosure under this ASU. We continue to monitor additional authoritative or interpretive guidance related to this ASU as it becomes available, as well as comparing our conclusions on specific interpretative issues to other peers in our industry, to the extent that such information is available to us. We currently anticipate utilizing a modified retrospective adoption as of April 1, 2018.

Note 4—Acquisitions

The following summarizes our acquisitions during the six months endedSeptember 30, 2017:

Acquisition of Remaining Interest in NGL Solids Solutions, LLC

On April 17, 2017, we entered into a purchase and sale agreement with the party owning the 50% noncontrolling interest in NGL Solids Solutions, LLC, a consolidated subsidiary, in our Water Solutions segment. Total consideration was $23.1 million, which consisted of cash of $20.0 million and the termination of a non-compete agreement that we valued at $3.1 million and in return we received the following:

15

NGL ENERGY PARTNERS LP AND SUBSIDIARIES

Notes to Unaudited Condensed Consolidated Financial Statements (Continued)

• The remaining 50% interest in NGL Solids Solutions, LLC; and

• Two parcels of land to develop saltwater disposal wells.

We accounted for the transaction as an acquisition of assets. Acquiring assets in groups requires not only ascertaining the cost of the asset (or net asset) group but also allocating that cost to the individual assets (or individual assets and liabilities) that make up the group. The cost of a group of assets acquired in an asset acquisition is allocated to the individual assets acquired or liabilities assumed/released based on their relative fair values and does not give rise to goodwill or bargain purchase gains. We allocated $22.9 million to noncontrolling interest and $0.2 million to land. 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 50% noncontrolling interest had a carrying value of $16.6 million. For the termination of the non-compete agreement, we recorded a gain of $1.3 million, which included the carrying value of the non-compete agreement intangible asset that was written off (see Note 7). This gain was recorded within loss (gain) on disposal or impairment of assets, net in our unaudited condensed consolidated statement of operations during the six months endedSeptember 30, 2017.

Retail Propane Businesses

During the six months endedSeptember 30, 2017, we acquired four retail propane businesses for total consideration of $29.3 million. The agreements for these acquisitions contemplate post-closing payments for certain working capital items.

We are in the process of identifying and determining the fair values of the assets acquired and liabilities assumed for these retail propane businesses, and as a result, the estimates of fair value at September 30, 2017 are subject to change. The following table summarizes the preliminary estimates of the fair values of the assets acquired and liabilities assumed (in thousands):

Current assets	$	1,880
Property, plant and equipment	10,051
Goodwill	4,150
Intangible assets	14,875
Current liabilities	(1,484		)
Other noncurrent liabilities	(134		)
Fair value of net assets acquired	$	29,338

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 acquire the skilled workforce of each of the businesses acquired and the ability to expand into new markets. We expect that all of the goodwill will be deductible for federal income tax purposes.

The operations of these retail propane businesses have been included in our unaudited condensed consolidated statement of operations since their acquisition date. Our unaudited condensed consolidated statement of operations for the six months endedSeptember 30, 2017 includes revenues of $2.8 million and operating income of less than $0.1 million that were generated by the operations of two of these retail propane businesses. The revenues and operating income of the other retail propane business acquisitions are not considered material.

The following summarizes the status of the preliminary purchase price allocation of acquisitions prior to April 1, 2017:

Water Solutions Facilities

During the six months ended September 30, 2017, we completed the acquisition accounting for two water solutions facilities. During the six months ended September 30, 2017, we received additional information and recorded a decrease of $0.2 million to property, plant and equipment and an increase of less than $0.1 million to other noncurrent liabilities related to an asset retirement obligation. The offset of these adjustments was recorded to goodwill.

Retail Propane Businesses

During the six months ended September 30, 2017, we completed the acquisition accounting for three retail propane businesses. During the six months ended September 30, 2017, we received additional information and recorded a decrease of $0.2 million to current assets and a decrease of less than $0.1 million to property, plant and equipment. The offset of these adjustments was recorded to goodwill. In addition, we paid $0.4 million in cash to the sellers during the six months ended September 30, 2017 for consideration that was held back at the acquisition date, which we recorded as a liability within accrued expenses and other payables in our unaudited condensed consolidated balance sheet.

Natural Gas Liquids Facilities

During the three months ended June 30, 2017, we completed the acquisition accounting for certain natural gas liquids facilities acquired in January 2017. There were no material adjustments to the fair value of assets acquired and liabilities assumed during the three months ended June 30, 2017.

Note 5—Property, Plant and Equipment

Our property, plant and equipment consists of the following at the dates indicated:

Description	Estimated Useful Lives	September 30, 2017			March 31, 2017

Notes to Unaudited Condensed Consolidated Financial Statements (Continued)

We record losses (gains) from the sales of property, plant and equipment and any write-downs in value due to impairment within loss (gain) on disposal or impairment of assets, net in our unaudited condensed consolidated statements of operations. During the three months endedSeptember 30, 2017, we recorded a net loss of $1.9 million, of which $0.4 million related to a gain on the sale of excess pipe in our Crude Oil Logistics segment. During the six months endedSeptember 30, 2017, we recorded a net gain of $0.6 million, of which $3.8 million related to the gain on the sale of excess pipe in our Crude Oil Logistics segment. The gain was partially offset by losses from the sale of certain assets and the write down of certain other assets.

Goodwill Impairment

Due to the decreased demand for natural gas liquid storage and resulting decline in revenues and earnings as compared to actual and projected results of prior and future periods, we tested the goodwill within our natural gas liquids salt cavern storage reporting unit (“Sawtooth reporting unit”), which is part of our Liquids segment, for impairment at September 30, 2017. We estimated the fair value of our Sawtooth reporting unit based on the income approach, also known as the discounted cash flow method, which utilizes the present value of future expected cash flows to estimate the fair value. The future cash flows of our Sawtooth reporting unit were projected based upon estimates as of the test date of future revenues, operating expenses and cash outflows necessary to support these cash flows, including working capital and maintenance capital expenditures. We also considered expectations regarding: (i) expected storage volumes, which are assumed to increase in the coming years due to increased production of natural gas liquids, (ii) expected propane and butane prices and (iii) expected rental fees. We assumed a 2% per year increase in commodity prices and a 4% increase in rental fees per year starting in April 2018, and held such prices and fees flat for periods in our model beyond our 2023 fiscal year. For expenses, we assumed an increase consistent with the increase in storage volumes, and maintenance capital was held flat throughout the model. The discount rate used in our discounted cash flow method was a risk adjusted weighted average cost of capital calculated as of September 30, 2017 of 12%. The discounted cash flow results indicated that the estimated fair value of our Sawtooth reporting unit was less than its carrying value by approximately 32% at September 30, 2017.

During the three months ended September 30, 2017, we recorded a goodwill impairment charge of $116.9 million, which was recorded within loss (gain) on disposal or impairment of assets, net, in our unaudited condensed consolidated statement of operations. At September 30, 2017, our Sawtooth reporting unit had a goodwill balance of $66.2 million.

Our estimated fair value is predicated upon management’s assumption of the growth in the production of natural gas liquids and the decline in the use of railcars to store natural gas liquids. We used these assumptions to estimate the demand for storage at our facility and the revenue generated by customers reserving capacity at our facility. Due to the current volatility in commodity prices and the excess railcars currently in the market, we believe it is reasonably possible that the need for underground storage we estimate in our model does not materialize, such that our estimate of fair value could change and result in further impairment of the goodwill in our Sawtooth reporting unit.

Credit Agreement

We are party to a $1.765 billion credit agreement (the “Credit Agreement”) with a syndicate of banks. As of September 30, 2017, the Credit Agreement includes a revolving credit facility to fund working capital needs, which had a capacity of $1.05 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 $715.0 million (the “Expansion Capital Facility,” and together with the Working Capital Facility, the “Revolving Credit Facility”). During the three months endedSeptember 30, 2017, we reallocated $50.0 million from the Expansion Capital Facility to the Working Capital Facility. We had letters of credit of $115.1 million on the Working Capital Facility at September 30, 2017.

At September 30, 2017, the borrowings under the Credit Agreement had a weighted average interest rate of 4.50%, calculated as the weighted average LIBOR rate of 1.24% plus a margin of 3.00% for LIBOR borrowings and the prime rate of 4.25% plus a margin of 2.00% on alternate base rate borrowings. At September 30, 2017, the interest rate in effect on letters of credit was 3.00%. Commitment fees were charged at a rate ranging from 0.375% to 0.50% on any unused capacity.

On June 2, 2017, we amended our Credit Agreement. The amendment, among other things, restricts us from increasing our distribution rate over the amount paid in the preceding quarter if our leverage ratio is greater than 4.25 to 1. The following table summarizes the debt covenant levels specified in the Credit Agreement as of September 30, 2017:

		Senior Secured	Interest
Period Beginning	Leverage Ratio (1)	Leverage Ratio (1)	Coverage Ratio (2)
September 30, 2017	5.50	2.50	2.25
March 31, 2018	4.75	3.25	2.75
March 31, 2019 and thereafter	4.50	3.25	2.75

(1) Amount represents the maximum ratio for the period presented.

(2) Amount represents the minimum ratio for the period presented.

At September 30, 2017 our leverage ratio was approximately 5.42 to 1, our senior secured leverage ratio was approximately 0.75 to 1 and our interest coverage ratio was approximately 2.26 to 1.

At September 30, 2017, we were in compliance with the covenants under the Credit Agreement.

Senior Secured Notes

During the six months endedSeptember 30, 2017, we repurchased $55.0 million of our senior secured notes for an aggregate purchase price of $57.2 million (excluding payments of accrued interest), and recorded a loss on the early extinguishment of $3.2 million (net of $1.0 million of debt issuance costs.) Following the repurchase, semi-annual installment payments will be $19.5 million beginning on December 19, 2017 and ending on the maturity date of June 19, 2022.

On August 2, 2017, we amended the note purchase agreement for our senior secured notes with an effective date of June 2, 2017. The amendment, among other things, conforms the financial covenants to match the amended terms of the Credit Agreement and provides for an increase in interest charged if our leverage ratio exceeds certain predetermined levels.In addition, the amendment also restricts us from increasing our distribution rate over the amount paid in the preceding quarter if our interest coverage ratio is less than 3.00 to 1.

At September 30, 2017, we were in compliance with the covenants under the note purchase agreement for our senior secured notes.

Senior Unsecured Notes

Registration Rights

In connection with the issuance of the 7.50% senior notes due 2023 (the “2023 Notes”) and the 6.125% senior notes due 2025 (the “2025 Notes”), we entered into a registration rights agreement in which we agreed to file a registration statement

with the SEC so that the holders can exchange the 2023 Notes and the 2025 Notes for registered notes that have substantially identical terms as the 2023 Notes and the 2025 Notes and evidence the same indebtedness of the 2023 Notes and the 2025 Notes. In addition, the subsidiary guarantors agreed to exchange the guarantee related to the 2023 Notes and the 2025 Notes for a registered guarantee having substantially the same terms as the original guarantee. We filed a registration statement for both the 2023 Notes and the 2025 Notes with the SEC which became effective on July 11, 2017 and 99.98% of the 2023 Notes and 99.98% of the 2025 Notes were exchanged on August 8, 2017.

Note 9—Commitments and Contingencies

Legal Contingencies

We are party to various claims, legal actions, and complaints arising in the ordinary course of business. In the opinion of our management, the ultimate resolution of these 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

Our unaudited condensed consolidated balance sheet at September 30, 2017 includes a liability, measured on an undiscounted basis, of $2.1 million related to environmental matters, 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.

As previously disclosed, the U.S. Environmental Protection Agency (“EPA”) had informed NGL Crude Logistics, LLC, formerly known as Gavilon, LLC (“Gavilon Energy”), of alleged violations in 2011 by Gavilon Energy of the Clean Air Act’s renewable fuel standards regulations (prior to its 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, which was denied on May 24, 2017. On October 17, 2017, the EPA filed a motion for partial summary judgment against Gavilon Energy. Consistent with our position against the previous EPA allegations, we deny the allegations in the amended civil complaint and that the EPA is entitled to summary judgment and we intend to continue vigorously defending ourselves in the civil action. However, at this time we are unable to determine the outcome of this action or its significance to us.

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, 2017	$	8,181
Liabilities incurred	422
Liabilities assumed in acquisitions	21
Liabilities settled	(233		)
Accretion expense	511
Balance at September 30, 2017	$	8,902

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 September 30, 2017 (in thousands):

Fiscal Year Ending March 31,
2018 (six months)	$	71,787
2019	120,589
2020	107,255
2021	94,118
2022	65,985
Thereafter	93,844
Total	$	553,578

Rental expense relating to operating leases was $32.5 million and $27.0 million during the three months endedSeptember 30, 2017 and 2016, respectively, and $63.8 million and $56.9 million during the six months endedSeptember 30,2017 and 2016, respectively.

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. We currently have an asset recorded in other noncurrent assets in our unaudited condensed consolidated balance sheet for minimum shipping fees paid in previous periods that are expected to be recovered in future periods by exceeding the minimum monthly volumes (see Note 2).

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 September 30, 2017, we had the following commodity purchase commitments (in thousands):

(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.

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 $28.1 million of our prepaid expenses and other current assets and $28.2 million of our accrued expenses and other payables at September 30, 2017.

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 converted to common units during the six months endedSeptember 30, 2017, we issued 333 notional units to our general partner for less than $0.1 million in order to maintain its 0.1% interest in us.

Common Unit Repurchase Program

On August 29, 2017, the board of directors of our general partner authorized a common unit repurchase program, under which we may repurchase up to $15.0 million of our outstanding common units through December 31, 2017from time to time in the open market or in other privately negotiated transactions. During the three months endedSeptember 30, 2017, we repurchased 1,193,635common units for an aggregate price of $11.2 million, including commissions.

Our Distributions

The following table summarizes distributions declared on our common units during the last three 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, 2017	May 8, 2017	May 15, 2017	$	0.3900	$	46,870	$	80

October 19, 2017	November 6, 2017	November 14, 2017	$	0.3900	$	47,000	$	81

Class A Convertible Preferred Units

On April 21, 2016, we received net proceeds $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 the warrants. Accretion for the beneficial conversion feature, recorded as a deemed distribution, was $4.0 million and $2.2 million during the three months endedSeptember 30, 2017 and 2016, respectively, and $7.2 million and $3.8 million during the six months endedSeptember 30, 2017 and 2016, respectively.

The holders of the warrants may convert 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. During the six months endedSeptember 30, 2017, 607,653 warrants were converted to common units and we received proceeds of less than $0.1 million. In addition, we repurchased 850,716 unvested warrants for a total purchase price of $10.5 million on June 23, 2017. As of September 30, 2017, we had 2,916,743 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 three quarters:

		Amount Paid/Payable to Class A
Date Declared	Date Paid/Payable	Preferred Unitholders
		(in thousands)
April 24, 2017	May 15, 2017	$	6,449
July 20, 2017	August 14, 2017	$	6,449
October 19, 2017	November 14, 2017	$	6,449

Class B Preferred Units

During the six months endedSeptember 30, 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 $202.8 million (net of the underwriters’ discount of $6.6 million and offering costs of $0.6 million).

At any time on or after July 1, 2022, we may redeem our Class B Preferred Units, in whole or in part, at a redemption price of $25.00 per Class B Preferred Unit plus an amount equal to all accumulated and unpaid distributions to, but not including, the date of redemption, whether or not declared. We may also redeem the Class B Preferred Units upon a change of control as defined in our partnership agreement. If we choose not to redeem the Class B Preferred Units, the Class B preferred unitholders may have the ability to convert the Class B Preferred Units to common units at the then applicable conversion rate. Class B preferred unitholders have no voting rights except with respect to certain matters set forth in our partnership agreement.

NGL ENERGY PARTNERS LP AND SUBSIDIARIES

Notes to Unaudited Condensed Consolidated Financial Statements (Continued)

Distributions on the Class B Preferred Units are payable on the 15th day of each January, April, July and October of each year (beginning on October 15, 2017) to holders of record on the first day of each payment month. The initial distribution rate for the Class B Preferred Units from and including the date of original issue to, but not including, July 1, 2022 is 9.00% per year of the $25.00 liquidation preference per unit (equal to $2.25 per unit per year). On and after July 1, 2022, distributions on the Class B Preferred Units will accumulate at a percentage of the $25.00 liquidation preference equal to the applicable three-month LIBOR plus a spread of 7.213%. On September 18, 2017, the board of directors of our general partner declared a distribution for the three months endedSeptember 30, 2017 of $5.7 million, for which the amount is included in accrued expenses and other payables in our unaudited condensed consolidated balance sheet at September 30, 2017. The distribution was paid to the holders of the Class B Preferred Units on October 16, 2017.

Amended and Restated Partnership Agreement

On June 13, 2017, NGL Energy Holdings LLC executed the Fourth Amended and Restated Agreement of Limited Partnership. The preferences, rights, powers and duties of holders of the Class B Preferred Units are defined in the amended and restated partnership agreement. The Class B Preferred Units rank senior to the common units, with respect to the payment of distributions and distribution of assets upon liquidation, dissolution and winding up and are on parity with the Class A Preferred Units. The Class B Preferred Units have no stated maturity but we may redeem the Class B Preferred Units at any time on or after July 1, 2022. Upon the occurrence of a change in control, we may redeem the Class B Preferred Units.

At-The-Market Program

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 six months endedSeptember 30, 2017, and approximately $134.7 million remained available for sale under the ATM Program at September 30, 2017.

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”).

On April 1, 2017, we made an accounting policy election to account for actual forfeitures, rather than estimate forfeitures each period (as previously required). As a result, the cumulative effect adjustment, which represents the differential between the amount of compensation expense previously recorded and the amount that would have been recorded without assuming forfeitures, had no impact on our consolidated financial statements.

The following table summarizes the Service Award activity during the six months endedSeptember 30, 2017:

Unvested Service Award units at March 31, 2017	2,708,500
Units granted	137,921
Units vested and issued	(956,821	)
Units forfeited	(51,300	)
Unvested Service Award units at September 30, 2017	1,838,300

In connection with the vesting of certain restricted units during the six months endedSeptember 30, 2017, we canceled 37,554 of the newly-vested common units in satisfaction of $0.5 million of employee tax liability paid by us. Pursuant to the terms of the LTIP, these canceled units are available for future grants under the LTIP.

Notes to Unaudited Condensed Consolidated Financial Statements (Continued)

The following table summarizes the scheduled vesting of our unvested Service Award units at September 30, 2017:

Fiscal Year Ending March 31,
2018 (six months)	—
2019	919,350
2020	914,450
2021	4,500
Total	1,838,300

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 endedSeptember 30, 2017 and 2016, we recorded compensation expense related to Service Award units of $3.3 million and $25.8 million, respectively. During the six months endedSeptember 30, 2017 and 2016, we recorded compensation expense related to Service Award units of $8.6 million and $46.7 million, respectively.

Of the restricted units granted and vested during the six months endedSeptember 30, 2017, 66,421 units were granted as a bonus for performance during the fiscal year ended March 31, 2017. We accrued expense of $0.9 million during the fiscal year ended March 31, 2017 as an estimate of the value of such bonus units that would be granted.

The following table summarizes the estimated future expense we expect to record on the unvested Service Award units at September 30, 2017 (in thousands):

Fiscal Year Ending March 31,
2018 (six months)	$	5,865
2019	10,697
2020	2,827
2021	13
Total	$	19,402

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 September 30, 2017, 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

The following table summarizes the Performance Award activity during the six months endedSeptember 30, 2017:

Unvested Performance Award units at March 31, 2017	1,189,000
Units forfeited	(404,000	)
Unvested Performance Award units at September 30, 2017	785,000

During the July 1, 2014 through June 30, 2017 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, 2017 and performance units with the July 1, 2017 vesting date are considered to be forfeited.

29

NGL ENERGY PARTNERS LP AND SUBSIDIARIES

Notes to Unaudited Condensed Consolidated Financial Statements (Continued)

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 endedSeptember 30, 2017 and 2016, we recorded compensation expense related to Performance Award units of $1.3 million and $1.6 million, respectively. During the six months endedSeptember 30, 2017 and 2016, we recorded compensation expense related to Performance Awards units of $3.4 million and $3.1 million, respectively.

The following table summarizes the estimated future expense we expect to record on the unvested Performance Award units at September 30, 2017 (in thousands):

Fiscal Year Ending March 31,
2018 (six months)	$	2,635
2019	3,167
2020	642
Total	$	6,444

At September 30, 2017, approximately 3.2 million common units remain available for issuance under the LTIP.

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.

During the three months and six months endedSeptember 30, 2017, we recorded a net loss of $71.4 million and $34.9 million, respectively, and during the three months and six months endedSeptember 30, 2016, we recorded a net gain of $14.7 million and a net loss of $45.0 million, respectively, 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. AtSeptember 30, 2017, 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.AtSeptember 30, 2017, we had$971.5 millionof outstanding borrowings under our Revolving Credit Facility at a weighted average interest rate of4.50%.

Fair Value of Fixed-Rate Notes

The following table provides fair value estimates of our fixed-rate notes at September 30, 2017 (in thousands):

Senior secured notes	$	201,715
Senior unsecured notes:
5.125% Notes due 2019	$	360,673
6.875% Notes due 2021	$	366,938
7.500% Notes due 2023	$	670,605
6.125% Notes due 2025	$	451,004

For the senior secured notes, the fair value estimate was developed using observed yields on publicly traded notes issued by us, adjusted for differences in the key terms of those notes and the key terms of our notes (examples include differences in the tenor of the debt, credit standing of the issuer, whether the notes are publicly traded, and whether the notes are secured or unsecured). This fair value estimate would be classified as Level 3 in the fair value hierarchy. 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 certain financial data related to our segments. 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.

Note 15—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.

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.

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 and six months endedSeptember 30, 2017 are not necessarily indicative of the results of operations to be expected for future periods or for the full fiscal year ending March 31, 2018. See the detailed discussion of items affecting operating income (loss) by segment below.

Recent Developments

Senior Secured Notes

On August 2, 2017, we amended the note purchase agreement for our senior secured notes with an effective date of June 2, 2017. The amendment, among other things, conforms the financial covenants to match the amended terms of the Credit Agreement (as defined herein), provides for an increase in interest charged if our leverage ratio exceeds certain predetermined levels and restricts us from increasing our distribution rate. See Note 8 to our unaudited condensed consolidated financial statements included in this Quarterly Report for a further description.

47

Repurchases of Senior Unsecured Notes

During the three months endedSeptember 30, 2017, we repurchased $1.5 million of the 5.125% senior notes due 2019 (the “2019 Notes”), $26.5 million of the 7.50% senior notes due 2023 (the “2023 Notes”), and $15.7 million of the 6.125% senior notes due 2025 (the “2025 Notes”). See Note 8 to our unaudited condensed consolidated financial statements included in this Quarterly Report for a further discussion.

Common Unit Repurchase Program

On August 29, 2017, the board of directors of our general partner authorized a common unit repurchase program, under which we may repurchase up to $15.0 million of our outstanding common units through December 31, 2017from time to time in the open market or in other privately negotiated transactions. During the three months endedSeptember 30, 2017, we repurchased 1,193,635common units for an aggregate price of $11.2 million, including commissions.

Acquisitions

As discussed below, we completed numerous acquisitions during the fiscal year ended March 31, 2017 and the six months endedSeptember 30, 2017. These acquisitions impact the comparability of our results of operations between our current and prior fiscal years.

During the six months endedSeptember 30, 2017, in our Water Solutions segment, we acquired the remaining 50% ownership interest in NGL Solids Solutions, LLC, and in our Retail Propane segment, we acquired four retail propane businesses. See Note 4 to our unaudited condensed consolidated financial statements included in this Quarterly Report for a further discussion.

During the fiscal year ended March 31, 2017, we acquired:

• three water solutions facilities;

• the remaining 25% ownership interest in three water solutions facilities;

• an additional 24.5% interest in an existing produced water pipeline company;

• the remaining 65% ownership interest in Grassland Water Solutions, LLC (“Grassland”), in which we subsequently sold 100% of our interest;

• four retail propane businesses; and

• certain natural gas liquids facilities.

(2) Information is presented as ofSeptember 30, 2017andSeptember 30, 2016, respectively.

Crude Oil Sales.Theincreasewas due primarily toan increasein crude oil prices and barrels sold during thethree months endedSeptember 30, 2017, compared to thethree months endedSeptember 30, 2016. 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 volumes in this lower price environment to support our various pipeline, terminal and transportation assets.

Crude Oil Transportation and Other Revenues.Theincreasewas due primarily to our Grand Mesa Pipeline becoming operational on November 1, 2016 with revenues of$19.1 million and higher revenues in our trucking and barge operations during the three months endedSeptember 30, 2017, due to an increase in demand for transportation services, compared to the three months endedSeptember 30, 2016, partially offset by the flattening of the contango curve for crude oil (a condition in which forward crude oil prices are greater than spot prices) during thethree months endedSeptember 30, 2017, compared to thethree months endedSeptember 30, 2016.

Cost of Sales.Theincreasewas due primarily toan increasein crude oil prices during thethree months endedSeptember 30, 2017, compared to thethree months endedSeptember 30, 2016.Our cost of sales during thethree months endedSeptember 30, 2017wasincreased by $0.2 million of net realized losses on derivatives and $2.2 million of net unrealized losses on derivatives. Our cost of sales during thethree months endedSeptember 30, 2016 was reduced by $2.7 million of net realized gains on derivatives and increased by $1.6 million of net unrealized losses on derivatives.

Operating and General and Administrative Expenses.Theincreasewas due primarily to our Grand Mesa Pipeline project becoming operational on November 1, 2016. During thethree months endedSeptember 30, 2017, we incurred expenses of$3.7 millionrelated to Grand Mesa.Thisincrease was partially offset by lower repair and maintenance expense related to having a newer fleet of barges and the timing of repairs, lower repair and maintenance expense and lower insurance expense related to having a smaller fleet of trucks, and lower property taxes due to decreased inventory.

Depreciation and Amortization Expense.Theincreasewas due primarily to our Grand Mesa Pipeline project becoming operational on November 1, 2016. During thethree months endedSeptember 30, 2017, we incurred depreciation and amortization expense of$10.6 millionrelated to Grand Mesa.Also contributing to the increase was higher depreciation expense related to other capital projects being placed into service.

(Gain) Loss on Disposal or Impairment of Assets, Net. During the three months endedSeptember 30, 2017, we recorded a net gain of $0.2 million on the sales of excess pipe and certain other assets. During the three months endedSeptember 30, 2016, we recorded a net loss of $4.8 million on the sales of certain assets and a loss of $3.7 million due to the write-down of certain other assets.

Operating expenses for wastewater processed ($/barrel)	$	0.39		$	0.44		$	(0.05	)

Service Fee Revenues.Theincreasewas due primarily toan increasein the volume of wastewater processed at existing facilities, partially offset with higher volumes in areas with lower fees. We continue to benefit from the increased rig counts, from the prior year, in the basins in which we operate, particularly in the Permian Basin.

50

Recovered Hydrocarbon Revenues.Theincreasewas due primarily toan increasein the volume of wastewater processed and an increase in the amount of hydrocarbons per barrel of wastewater processed.

Other Revenues.Other revenues primarily include solids disposal revenues and water pipeline revenues. Thedecreasewas due primarily toa decrease in freshwater revenues due to the sale of Grassland in November 2016 and lower revenues from trucking wastewater to our water solutions facilities in one basin due to a new water pipeline being placed into service during thethree months endedSeptember 30, 2017. These decreases were partially offset by an increase in volumes for solids disposal and water pipeline businesses.

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 endedSeptember 30, 2017included$0.8 million of net realized gains on derivatives and $3.0 million of net unrealized losses on derivatives. Our cost of sales during thethree months endedSeptember 30, 2016included $2.2 million of net unrealized gains on derivatives and $0.2 million of net realized gains on derivatives.

Cost of Sales-Other. The decrease was due to lower trucking expenses to bring wastewater to our water solutions facilitiesin one basindue to a new water pipeline being placed into service during thethree months endedSeptember 30, 2017, partially offset by an increase in expenses for newly offered trucking services to bring wastewater to our water solutions facilitiesin another basin.

Operating and General and Administrative Expenses.Theincreasewas due primarily tohigheroperating costs of water disposal wells due tohighervolumes processed, partially offset by cost reduction efforts.

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, 2017.

Loss (Gain) on Disposal or Impairment of Assets, Net. During the three months endedSeptember 30, 2017, we recorded a net loss of $0.9 million on the sales of certain assets. During the three months endedSeptember 30, 2016, we recorded a net gain of less than $0.1 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 endedMarch 31, 2017. Theincreasein the expense during thethree months endedSeptember 30, 2017was due primarily to higher actual and expected production from new customers, resulting in an increase to the expected future royalty payment.

52

Propane Sales. The increase in revenues was due to increased sales volumes and higher commodity prices.

Our cost of wholesale propane sales was reduced by $5.8 million of net unrealized gains on derivatives and increased by less than $0.1 million of net realized losses on derivatives during the three months endedSeptember 30, 2017. During the three months endedSeptember 30, 2016, our cost of wholesale propane sales was reduced by $0.1 million of net unrealized gains on derivatives and increased by less than $0.1 million of net realized losses on derivatives.

Propane margins are higher due primarily to the increase in market prices outpacing the rise in inventory values.

Butane Sales. The increase in revenues and cost of sales was due primarily to higher commodity prices and increased volumes sold due to increased demand in the market place.

Our cost of butane sales during the three months endedSeptember 30, 2017 was increased by $18.2 million of net unrealized losses on derivatives, compared to an increase of $3.3 million of net unrealized losses on derivatives during the three months endedSeptember 30, 2016. Additionally, our cost of butane sales was reduced by $0.6 million of net realized gains on derivatives and $0.6 million of net realized gains on derivatives during the three months endedSeptember 30, 2017 and 2016, respectively.

Product margins per gallon of butane were lower during the three months endedSeptember 30, 2017 than during the three months endedSeptember 30, 2016 due primarily to the unrealized losses on derivatives noted above. The butane product margins, excluding the unrealized losses on derivatives, were $0.038 per gallon for the three months endedSeptember 30, 2017.

Other Products Sales. The increase in the volume of other products sold was due primarily to a new long-term marketing agreement. Volumes have also increased with the addition of the new Port Hudson and Kingfisher terminals.

Our cost of sales of other products was increased by $0.3 million of net unrealized losses on derivatives and reduced by net realized gains on derivatives of $0.1 million during the three months endedSeptember 30, 2017. Our cost of sales of other products during the three months endedSeptember 30, 2016 was reduced by $0.7 million of net unrealized gains on derivatives and $0.1 million of net realized gains on derivatives.

Product margins during the three months endedSeptember 30, 2017 were reduced due to an increase in unrecovered railcar fleet costs.

Other Revenues. This revenue includes storage, terminaling and transportation services income. The decrease was due to a decline in hauling activity and lower storage service income.

Operating and General and Administrative Expenses. This decrease was due primarily to lower compensation expense, $2.8 million of which resulted from a shift in the recording of compensation expense related to bonuses from the Liquids segment to “Corporate and Other” during the three months endedSeptember 30, 2017. See further discussion within the “Corporate and Other” section below.

Depreciation and Amortization Expense. Theincrease was due primarily to additional assets being placed into service as well as the acquisition of two liquids facilities during the previous fiscal year.

Loss on Disposal or Impairment of Assets, Net. During the three months endedSeptember 30, 2017, we recorded a goodwill impairment charge of $116.9 million due to the decreased demand for natural gas liquid storage and resulting decline in revenues and earnings as compared to actual and projected results of prior and future periods (see Note 6 to our unaudited condensed consolidated financial statements included in this Quarterly Report). During the three months endedSeptember 30, 2017, we recorded a net loss of $0.9 million related to the retirement of assets. During the three months endedSeptember 30, 2016, we recorded a net loss of less than $0.1 million related to the retirement of assets.

(2) Information is presented as of September 30, 2017 and September 30, 2016, respectively.

Revenues. Propane revenues and volumes increased due to acquisitions in the current year and prior year and an increase in commodity prices. Distillates revenues and volumes increased due to acquisitions and an increase in commodity prices.

Cost of Sales. The increase in propane cost is due to the current and prior year acquisitions as well as an increase in commodity prices. The distillates cost increase was due to an increase in volumes resulting from acquisitions as well as an increase in commodity prices.

54

Operating and General and Administrative Expenses. The increase was due primarily to increased operating expenses and integration costs from acquisitions of four retail propane businesses during the previous fiscal year and four retail propane businesses in the current year.

Depreciation and Amortization Expense. The increase was due primarily to the acquisition of four retail propane businesses during the previous fiscal year and four retail propane businesses in the current year.

Refined Products Revenues and Cost of Sales.Theincreasesin revenues and cost of sales were due toan increasein refined products prices andincreasedvolumes.Theincreased volumes were due primarily to an expansion of our refined

56

products operations, the continued demand for motor fuels and the Colonial Pipeline being down for maintenance for a portion of the prior year quarter. The margin was higher during the three months endedSeptember 30, 2017 due primarily to an increase in Gulf Coast prices as a result of supply disruptions.

Renewables Revenues and Cost of Sales.Theincreasesin revenues and cost of sales were due primarily toan increase in renewables prices and increased volumes. The margin was lower during the three months endedSeptember 30, 2017 due primarily to unfavorable biodiesel margins.

Service Fee Revenues, Operating Expenses, General and Administrative Expenses.The changes were due primarily to the expiration of a transition services agreement in October 2016 related to the sale of all of the TransMontaigne Partners L.P. (“TLP”) units we owned whereby we were reimbursed for certain expenses incurred on behalf of a third party.

Depreciation and Amortization Expense.Thedecreasewas due primarily to certain assets being fully depreciated during the fiscal year ended March 31, 2017.

Gain on Disposal or Impairment of Assets, Net. During the three months endedSeptember 30, 2017, we recorded $7.5 millionof the deferred gain from the sale of the general partner in interest in TLP in February 2016 (seeNote 2to our unaudited condensed consolidated financial statements included in this Quarterly Report for a further discussion).

During the three months endedSeptember 30, 2016, we recorded:

• $7.5 millionof the deferred gain from the sale of the general partner in interest in TLP in February 2016 (seeNote 2to our unaudited condensed consolidated financial statements included in this Quarterly Report for a further discussion); and

• a gain of less than $0.1 million on the sales of certain assets.

Corporate and Other

The operating loss within “Corporate and Other” includes the following components for the periods indicated:

	Three Months Ended September 30,
	2017			2016			Change

Total expenses	16,705			23,661			(6,956		)
Operating loss	$	(16,459	)	$	(23,413	)	$	6,954

General and Administrative Expenses. The decrease during the three months endedSeptember 30, 2017 was due primarily to lower incentive compensation expense.

The decrease in incentive compensation was primarily related to our service awards units. During the three months endedSeptember 30, 2017, expense related to the service award units was $3.3 million, compared to $6.9 million during the three months endedSeptember 30, 2016. During the three months ended September 30, 2017, the expense for the service award units was lower due to the cancellation of certain service awards in the prior year quarter for which the expense had to be accelerated, as well as in the current year the number of units granted was significantly less than the number of units that have vested, thus, expense related to new grants has not fully replaced the expense from units that have fully vested during the period. In addition, compensation expense of $2.8 million was shifted from our Liquids segment during the three months endedSeptember 30, 2017 due to our expectation of paying these amounts in common units.

57

Equity in Earnings of Unconsolidated Entities

Theincreaseof$2.0 millionduring thethree months endedSeptember 30, 2017was due primarily to increased earnings related to our investments in Glass Mountain Pipeline, LLC (“Glass Mountain”) and E Energy Adams, LLC.

Interest Expense

Interest expense includes interest expense on our Revolving Credit Facility 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 increase of $16.8 million during the three months endedSeptember 30, 2017 was due primarily to the issuance of $700.0 million of fixed-rate notes during October 2016 and the issuance of $500.0 million of fixed-rate notes during February 2017.

Gain on Early Extinguishment of Liabilities, Net

The following table summarizes the components of gain on early extinguishment of liabilities, net for the periods indicated:

Income Tax Expense

Income tax expense was $0.1 million during the three months endedSeptember 30, 2017, compared to income tax expense of $0.5 million during the three months endedSeptember 30, 2016. The decrease in income tax expense was due primarily to a lower state franchise tax liability in Texas from a lower tax rate and lower Texas revenues as well as a lower Canadian tax liability from lower income in our taxable corporate subsidiaries in Canada. SeeNote 2to our unaudited condensed consolidated financial statements included in this Quarterly Report for a further discussion.

(2) Information is presented as ofSeptember 30, 2017andSeptember 30, 2016, respectively.

Crude Oil Sales.Theincreasewas due primarily toan increasein crude oil prices and barrels sold during thesix months endedSeptember 30, 2017, compared to thesix months endedSeptember 30, 2016. 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 volumes in this lower price environment to support our various pipeline, terminal and transportation assets.

Crude Oil Transportation and Other Revenues.Theincreasewas due primarily to our Grand Mesa Pipeline becoming operational on November 1, 2016 with revenues of$38.4 million and higher revenues in our trucking operations during the six months endedSeptember 30, 2017, due to an increase in demand for transportation services, compared to the six months endedSeptember 30, 2016, partially offset by the flattening of the contango curve for crude oil (a condition in which forward crude oil prices are greater than spot prices) during thesix months endedSeptember 30, 2017, compared to thesix months endedSeptember 30, 2016.

Cost of Sales.Theincreasewas due primarily toan increasein crude oil prices during thesix months endedSeptember 30, 2017, compared to thesix months endedSeptember 30, 2016. Our cost of sales during thesix months endedSeptember 30, 2017wasreduced by $4.2 million of net realized gains on derivatives and increased by $1.5 million of net unrealized losses on derivatives. Our cost of sales during thesix months endedSeptember 30, 2016 was increased by $5.5 million of net realized losses on derivatives and $0.2 million of net unrealized losses on derivatives.

59

Operating and General and Administrative Expenses.Theincreasewas due primarily to our Grand Mesa Pipeline project becoming operational on November 1, 2016. During thesix months endedSeptember 30, 2017, we incurred expenses of$6.9 millionrelated to Grand Mesa.Thisincrease was partially offset by lower repair and maintenance expense related to having a newer fleet of barges and the timing of repairs, lower repair and maintenance expense and lower insurance expense related to having a smaller fleet of trucks, and lower property taxes due to decreased inventory.

Depreciation and Amortization Expense.Theincreasewas due primarily to our Grand Mesa Pipeline project becoming operational on November 1, 2016. During thesix months endedSeptember 30, 2017, we incurred depreciation and amortization expense of$21.1 millionrelated to Grand Mesa.Also contributing to the increase was higher depreciation expense related to other capital projects being placed into service.

(Gain) Loss on Disposal or Impairment of Assets, Net. During the six months endedSeptember 30, 2017, we recorded a net gain of $3.7 million on the sales of excess pipe and certain other assets. During the six months endedSeptember 30, 2016, we recorded a net loss of $6.3 million on the sales of certain assets and a loss of $3.7 million due to the write-down of certain other assets.

Operating expenses for wastewater processed ($/barrel)	$	0.41		$	0.46		$	(0.05	)

Service Fee Revenues.Theincreasewas due primarily toan increasein the volume of wastewater processed at existing facilities, partially offset with higher volumes in areas with lower fees. We continue to benefit from the increased rig counts, from the prior year, in the basins in which we operate, particularly in the Permian Basin.

60

Recovered Hydrocarbon Revenues.Theincreasewas due primarily toan increasein the volume of wastewater processed and an increase in the amount of hydrocarbons per barrel of wastewater processed.

Other Revenues.Theincreasewas due primarily toan increase in volumes for solids disposal and water pipeline businesses. These increases were partially offset by a decrease in freshwater revenues due to the sale of Grassland in November 2016 (see below discussion of the loss on the sale of Grassland) and lower revenues from trucking wastewater to our water solutions facilities in one basin due to a new water pipeline being placed into service during thesix months endedSeptember 30, 2017.

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 thesix months endedSeptember 30, 2017included$1.0 million of net realized gains on derivatives and $3.0 million of net unrealized losses on derivatives. Our cost of sales during thesix months endedSeptember 30, 2016included $3.5 million of net realized losses on derivatives and $0.8 million of net unrealized gains on derivatives.

Cost of Sales-Other. The increase was due primarily to an increase in expenses for newly offered trucking services to bring wastewater to our water solutions facilitiesin one basin, partially offset by lower trucking expenses to bring wastewater to our water solutions facilitiesin another basindue to a new water pipeline being placed into service during thesix months endedSeptember 30, 2017.

Operating and General and Administrative Expenses.Theincreasewas due primarily tohigheroperating costs of water disposal wells due tohighervolumes processed, partially offset by cost reduction efforts.

Depreciation and Amortization Expense.Thedecrease was due primarily to lower amortization expense from the write-off of an intangible asset during the six months endedSeptember 30, 2016 as well as certain intangible assets being fully amortized during the fiscal year ended March 31, 2017, partially offset by acquisitions and developed facilities.

Loss (Gain) on Disposal or Impairment of Assets, Net. During the six months endedSeptember 30, 2017, we recorded a net loss of $1.5 million on the sales of certain assets, partially offset by a gain of $1.3 million for the termination of a non-compete agreement, which included the carrying value of the non-compete agreement intangible asset that was written off (see Note 7 to our unaudited condensed consolidated financial statements included in this Quarterly Report).

During the six months endedSeptember 30, 2016, we recorded:

• an adjustment of $124.7 million of the previously recorded $380.2 million estimated goodwill impairment charge recorded during the three months ended March 31, 2016;

• a write-off of $5.2 million related to the value of an indefinite-lived trade name intangible asset in conjunction with finalizing our goodwill impairment analysis in June 2016;

• a loss of $22.7 million related to the termination of a development agreement in June 2016, which included the carrying value of the development agreement asset that was written off;

• an impairment charge of $1.7 million to write down a loan receivable in June 2016; and

• a loss of $0.8 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 endedMarch 31, 2017. Theincreasein the expense during thesix months endedSeptember 30, 2017was due primarily to higher actual and expected production from new customers, resulting in an increase to the expected future royalty payment.

Propane Sales. The increase in revenues was due primarily to an increase in commodity prices. The propane volume increase was due primarily to a new long-term marketing agreement.

Our cost of wholesale propane sales was reduced by $5.5 million of net unrealized gains on derivatives and $0.1 million of net realized gains on derivatives during six months endedSeptember 30, 2017. During the six months endedSeptember 30, 2016, our cost of wholesale propane sales was reduced by $1.0 million of net unrealized gains on derivatives and $0.5 million of net realized gains on derivatives. The increase in cost of sales is due to an increase in commodity prices.

Product margins per gallon of propane sold were higher during the six months endedSeptember 30, 2017 than during the six months endedSeptember 30, 2016. Product margins have improved due to the increase in commodity prices.

Butane Sales. The increase in revenues and cost of sales was due primarily to higher commodity prices. Volumes increased due to favorable market conditions.

Our cost of butane sales during the six months endedSeptember 30, 2017 was increased by $16.5 million of net unrealized losses on derivatives, compared to an increase of $5.3 million of net unrealized losses on derivatives during the six months endedSeptember 30, 2016. Additionally, our cost of butane sales was reduced by $0.8 million of net realized gains on derivatives and $1.0 million of net realized gains on derivatives during the six months endedSeptember 30, 2017 and 2016, respectively, due to the steady increase in commodity prices beginning in July 2017.

Product margins per gallon of butane sold were lower during the six months endedSeptember 30, 2017 than during the six months endedSeptember 30, 2016 due primarily to the unrealized losses on derivatives noted above. The butane product margins, excluding the unrealized losses on derivatives, were $0.023 per gallon for the six months endedSeptember 30, 2017.

Other Products Sales. The increase in the volume of other products sold was due primarily to a new long-term marketing agreement. Volumes have also increased with the addition of the new Port Hudson and Kingfisher terminals.

Our cost of sales of other products was increased by $0.3 million of net unrealized losses on derivatives and reduced by $0.1 million of net realized gains on derivatives during the six months endedSeptember 30, 2017. Our cost of sales of other products during the six months endedSeptember 30, 2016 was reduced by $0.6 million of net unrealized gains on derivatives and $0.2 million of net realized gains on derivatives.

Product margins during the six months endedSeptember 30, 2017 were reduced due to an increase in unrecovered railcar fleet costs.

Other Revenues. This revenue includes storage, terminaling and transportation services income. Other revenues decreased due to transportation services and increased storage capacity available in the market.

Operating and General and Administrative Expenses. This decrease was due primarily to lower compensation expense, $2.8 million of which resulted from a shift in the recording of compensation expense related to bonuses from the Liquids segment to “Corporate and Other” during the six months endedSeptember 30, 2017. See further discussion within the “Corporate and Other” section below.

Depreciation and Amortization Expense. Theincrease was due primarily to the acquisition of two liquids facilities during the previous fiscal year.

Loss on Disposal or Impairment of Assets, Net. During the six months endedSeptember 30, 2017, we recorded a goodwill impairment charge of $116.9 million due to the decreased demand for natural gas liquid storage and resulting decline in revenues and earnings as compared to actual and projected results of prior and future periods (see Note 6 to our unaudited condensed consolidated financial statements included in this Quarterly Report). During the six months endedSeptember 30, 2017, we recorded a net loss of $0.9 million related to the retirement of assets. During the six months endedSeptember 30, 2016, we recorded a net loss of less than $0.1 million related to the retirement of assets.

Revenues. The increase for propane was due to the acquisitions in the prior year and current year as well as increased commodity prices. The increase for distillate revenues was due to higher commodity prices partially offset by lower volumes.

Cost of Sales. The increase for propane was due to an increase in commodity prices and acquisitions of retail propane businesses. The increase for distillate revenues was due to higher commodity prices partially offset by lower volumes.

64

Operating and General and Administrative Expenses. The increase was due primarily to increased operating expense from acquisitions of retail propane businesses.

Depreciation and Amortization Expense. The increase was due primarily to acquisitions of retail propane businesses.

purchased during the fiscal year ended March 31, 2017, an expansion of our refined products operations and the continued demand for motor fuels. The decrease in margin was due primarily to the negative impact of the continued decline in gasoline line space values on the Colonial Pipeline, discretionary terminal volume profitability and line space sales during the six months endedSeptember 30, 2017.

Renewables Revenues and Cost of Sales.Theincreasesin revenues and cost of sales were due primarily toincrease in renewables sale prices, partially offset by decreased volumes. The decreased volumes were due primarily to lower margins in current market conditions.

Service Fee Revenues, Operating Expenses, General and Administrative Expenses.The decrease was due primarily to the expiration of a transition services agreement in October 2016 related to the sale of all of the TLP units we owned whereby we were reimbursed for certain expenses incurred on behalf of a third party.

Depreciation and Amortization Expense.Thedecreasewas due primarily to certain assets being fully depreciated during the fiscal year ended March 31, 2017.

Gain on Disposal or Impairment of Assets, Net. During the six months endedSeptember 30, 2017, we recorded $15.1 millionof the deferred gain from the sale of the general partner in interest in TLP in February 2016 (seeNote 2to our unaudited condensed consolidated financial statements included in this Quarterly Report for a further discussion).

During the six months endedSeptember 30, 2016, we recorded:

• a $104.1 million gain from the sale of all of the TLP units we owned;

• $15.1 millionof the deferred gain from the sale of the general partner in interest in TLP in February 2016 (seeNote 2to our unaudited condensed consolidated financial statements included in this Quarterly Report for a further discussion); and

Operating loss	$	(34,185	)	$	(55,562	)	$	21,377

General and Administrative Expenses. The expense associated with the service award units was $8.6 million during the six months endedSeptember 30, 2017, compared to $27.7 million during the six months endedSeptember 30, 2016. During the six months endedSeptember 30, 2017, due to the cancellation of awards in the prior year which caused an acceleration of expense as well as vested units in July were not offset by grants as in the prior year. In addition, during the first quarter of our prior fiscal year the expense for the service awards being accounted for under the liability method and due to an increase in our unit price during that period we recorded an increase in equity-based compensation expense. See Note 10 to our unaudited condensed consolidated financial statements included in this Quarterly Report for a further discussion of our equity-based compensation awards. The decrease from the prior year was partially offset by $2.8 million of compensation expense that was shifted from our Liquids segment during the three months endedSeptember 30, 2017 due to our expectation of paying these amounts in common units.

Equity in Earnings of Unconsolidated Entities

Theincreaseof$3.4 millionduring thesix months endedSeptember 30, 2017was due primarily to increased earnings related to our investments inGlass Mountainand E Energy Adams, LLC.

Revaluation of Investments

As previously reported, on June 3, 2016, we acquired the remaining65%ownership interest in Grassland. Prior to the completion of this transaction, we accounted for our previously held 35% ownership interest in Grassland using the equity method of accounting. As we owned a controlling interest in Grassland, we revalued our previously held 35% ownership interest to fair value and recorded a loss of $14.9 million. As the amount paid (cash plus the fair value of our previously held ownership interest) was less than the fair value of the assets acquired and liabilities assumed, we recorded a bargain purchase gain of $0.6 million.

Interest Expense

The increase of $35.6 million during the six months endedSeptember 30, 2017 was due primarily to the issuance of $700.0 million of fixed-rate notes during October 2016 and the issuance of $500.0 million of fixed-rate notes during February 2017. The increase was partially offset by lower interest expense related to our credit facility. The average daily balance of our credit facility was $0.9 billion during the six months ended September 30, 2017, compared to $1.9 billion during the six months ended September 30, 2016.

(Loss) Gain on Early Extinguishment of Liabilities, Net

The following table summarizes the components of (loss) gain on early extinguishment of liabilities, net for the periods indicated:

	Six Months Ended September 30,
	2017			2016
	(in thousands)
Early extinguishment of long-term debt (1)	$	(1,338	)	$	8,614
Release of contingent consideration liabilities (2)	—			22,276
(Loss) gain on early extinguishment of liabilities, net	$	(1,338	)	$	30,890

(1) During the six months endedSeptember 30, 2017, this relates to net losses on the early extinguishment of a portion of the senior secured notes, the 2019 Notes, the 2023 Notes and the 2025 Notes. During the six months endedSeptember 30, 2016, this relates to gains on the early extinguishment of a portion of the 2019 Notes and the 6.875% senior notes due 2021 (“2021 Notes”). SeeNote 8to our unaudited condensed consolidated financial statements included in this Quarterly Report for a further discussion.

(2) Relates to the release of certain contingent consideration liabilities in conjunction with the termination of a development agreement in June 2016. Also, during the three months endedSeptember 30, 2016, we acquired certain parcels of land on which one of our water solutions facilities is located and recorded a gain on the release of certain contingent consideration liabilities as the royalty agreement was terminated.

Other Income, Net

The following table summarizes the components ofother income, netfor the periods indicated:

	Six Months Ended September 30,
	2017			2016
	(in thousands)
Interest income (1)	$	3,958		$	4,420
Crude oil marketing arrangement (2)	(10		)	(1,551		)
Other (3)	58			2,984
Other income, net	$	4,006		$	5,853

(1) Relates primarily toa loan receivable associated with our financing of the construction of a natural gas liquids facility to be utilized by a third partyand to a loan receivable from an equity method investee(seeNote 2andNote 13, respectively, to our unaudited condensed consolidated financial statements included in this Quarterly Report for a further discussion).As previously reported, on June 3, 2016, we acquired the remaining65%ownership interest in Grassland and all interest income on that receivable has been eliminated in consolidation subsequent to that date.

(2) Represents another party’s share of the profits and losses generated from a joint crude oil marketing arrangement.

(3) During the six months endedSeptember 30, 2016, this relates primarily to a distribution from TLP pursuant to the agreement to sell all of the TLP common units we owned in April 2016.

Income Tax Expense

Income tax expense was $0.6 million during the six months endedSeptember 30, 2017, compared to income tax expense of $0.9 million during the six months endedSeptember 30, 2016. The decrease in income tax expense was due primarily to a lower state franchise tax liability in Texas from a lower tax rate and lower Texas revenues as well as a lower Canadian tax liability from lower income in our taxable corporate subsidiaries in Canada. 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 decrease of $6.3 million during the six months endedSeptember 30, 2017 was due primarily to adjustments related to noncontrolling interests during the six months endedSeptember 30, 2016.

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, revaluation of investments, equity-based compensation expense, acquisition expense, revaluation of liabilities 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) income, (loss) income 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.

69

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.

The following table reconciles net (loss) income to EBITDA and 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 (as defined herein) 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.

73

Our borrowing needs vary during the year due in part to the seasonal nature of our Liquids, Retail Propane 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 inventories 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 Retail Propane and Liquids segments are the greatest and gasoline inventories need to be minimized due to certain inventory requirements.

Our partnership agreement requires that, within 45 days after the end of each quarter, we distribute all of our available cash (as defined in 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 (as defined herein) 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.

Under current market conditions, we are much less likely to pursue acquisitions than we have been in the past. We continue to undertake certain capital expansion projects, including the Glass Mountain pipeline extension, among others. We expect to be able to finance these projects through available capacity on our Revolving Credit Facility (as defined herein), asset sales or other forms of financing.

Other sources of liquidity during the six months endedSeptember 30, 2017 are discussed below.

Class B Preferred Units

During the six months endedSeptember 30, 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 $202.8 million (net of the underwriters’ discount of $6.6 million and offering costs of $0.6 million). See Note 10 to our unaudited condensed consolidated financial statements included in this Quarterly Report for a further description of the Class B Preferred Units.

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 September 30, 2017, the Credit Agreement includes a revolving credit facility to fund working capital needs, which had a capacity of $1.05 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 $715.0 million (the “Expansion Capital Facility,” and together with the Working Capital Facility, the “Revolving Credit Facility”). During the three months endedSeptember 30, 2017, we reallocated $50.0 million from the Expansion Capital Facility to the Working Capital Facility. We had letters of credit of $115.1 million on the Working Capital Facility at September 30, 2017.

On June 2, 2017, we amended our Credit Agreement to, among other things, modify our financial covenants. In addition, the amendment also restricts us from increasing our distribution rate over the amount paid in the preceding quarter if our leverage ratio is greater than 4.25 to 1.

At September 30, 2017, we were in compliance with the covenants under the Credit Agreement.

74

Senior Secured Notes

During the six months endedSeptember 30, 2017, we repurchased $55.0 million of our senior secured notes for an aggregate purchase price of $57.2 million (excluding payments of accrued interest), and recorded a loss on the early extinguishment of $3.2 million (net of $1.0 million of debt issuance costs). Following the repurchase, semi-annual installment payments will be $19.5 million beginning on December 19, 2017 and ending on the maturity date of June 19, 2022.

On August 2, 2017, we amended the note purchase agreement for our senior secured notes with an effective date of June 2, 2017. The amendment, among other things, conforms the financial covenants to match the amended terms of the Credit Agreement and provides for an increase in interest charged if our leverage ratio exceeds certain predetermined levels. In addition, the amendment also restricts us from increasing our distribution rate over the amount paid in the preceding quarter if our interest coverage ratio is less than 3.00 to 1.

At September 30, 2017, we were in compliance with the covenants under the note purchase agreement for our senior secured notes.

Senior Unsecured Notes

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

Repurchases

During the six months endedSeptember 30, 2017, we repurchased $18.7 million of the 2019 Notes, $26.5 million of the 2023 Notes, and $15.7 million of the 2025 Notes. See Note 8 to our unaudited condensed consolidated financial statements included in this Quarterly Report for a further discussion of the repurchases.

Compliance

AtSeptember 30, 2017, 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, senior secured notes and senior unsecured notes, see Note 8 to our unaudited condensed consolidated financial statements included in this Quarterly Report.

At-The-Market Program

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 are under no obligation to issue equity under the ATM Program. We did not issue any common units under the ATM Program during the six months endedSeptember 30, 2017, and approximately $134.7 million remained available for sale under the ATM Program as of September 30, 2017.

75

Common Unit Repurchase Program

On August 29, 2017, the board of directors of our general partner authorized a common unit repurchase program, under which we may repurchase up to $15.0 million of our outstanding common units through December 31, 2017from time to time in the open market or in other privately negotiated transactions. During the three months endedSeptember 30, 2017, we repurchased 1,193,635common units for an aggregate price of $11.2 million, including commissions.

Capital Expenditures

The following table summarizes expansion and maintenance capital expenditures for the periods indicated which excludes additions for tank bottoms and line fill. This information has been prepared on the accrual basis, and excludes property, plant and equipment and intangible assets acquired in acquisitions.

	Capital Expenditures
	Expansion		Maintenance		Total
	(in thousands)
Three Months Ended September 30,
2017	$	19,439	$	7,994	$	27,433
2016	$	48,781	$	6,401	$	55,182
Six Months Ended September 30,
2017	$	44,032	$	14,521	$	58,553
2016	$	143,884	$	12,696	$	156,580

During the three months and six months endedSeptember 30, 2017, we spent $28.5 million and $48.4 million, respectively, compared to $98.8 million and $113.3 million, respectively, during the three months and six months endedSeptember 30, 2016. See Note 4 to our unaudited condensed consolidated financial statements included in this Quarterly Report for a further discussion of the acquisitions made during our current fiscal year. In addition, we contributed $8.9 million and $14.2 million, respectively, during the three months and six months endedSeptember 30, 2017, for the construction of the Glass Mountain pipeline extension.

Cash Flows

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

	Six Months Ended September 30,
Cash Flows Provided by (Used in)	2017			2016
	(in thousands)
Operating activities, before changes in operating assets and liabilities	$	65,847		$	78,731
Changes in operating assets and liabilities	(55,893		)	(133,608		)
Operating activities	$	9,954		$	(54,877	)
Investing activities	$	(108,212	)	$	(235,542	)
Financing activities	$	104,401		$	285,670

Operating Activities. The seasonality of our natural gas liquids businesses has a significant effect on our cash flows from operating activities. Increases in natural gas liquids prices typically reduce our operating cash flows due to higher cash requirements to fund increases in inventories, 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 and Retail Propane businesses, we 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 blending 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 provided by

76

operating activities during the six months endedSeptember 30, 2017 was due primarily to higher inventory as a result of the purchase of additional pipeline capacity allocations in our Refined Products and Renewables segment during the six months endedSeptember 30, 2016.

Investing Activities. Net cash used in investing activities was $108.2 million during the six months endedSeptember 30, 2017, compared to $235.5 million during the six months endedSeptember 30, 2016. The decrease in net cash used in investing activities was due primarily to:

• a decrease in capital expenditures from $201.6 million during the six months endedSeptember 30, 2016, primarily related to the Grand Mesa Pipeline, to $56.5 million during the six months endedSeptember 30, 2017;

• a $64.9 milliondecrease in cash paid for acquisitions during the six months endedSeptember 30, 2017;

• a $24.2 millionincrease in proceeds primarily from the sale of excess pipe in our Crude Oil Logistics segment during the six months endedSeptember 30, 2017; and

• a $16.9 million payment to terminate a development agreement during the six months endedSeptember 30, 2016.

These decreases in net cash used in investing activities were partially offset by:

• $112.4 million in proceeds received from the sale of the TLP common units we owned during the six months endedSeptember 30, 2016; and

• $14.2 million of investments in unconsolidated entities during the six months endedSeptember 30, 2017.

Financing Activities. Net cash provided by financing activities was $104.4 million during the six months endedSeptember 30, 2017, compared to $285.7 million during the six months endedSeptember 30, 2016. The decrease in net cash provided by financing activities was due primarily to:

• an increase of $100.3 million in repurchases of a portion of our outstanding senior secured notes and senior unsecured notes during the six months endedSeptember 30, 2017;

• a decrease of $32.3 million in proceeds received from the sale of preferred units;

• an increase of $24.0 million in distributions paid to our general and common unit partners, preferred unitholders and noncontrolling interest owners during the six months endedSeptember 30, 2017;

• a decrease of $17.5 million in borrowings on our Revolving Credit Facility (net of repayments) during the six months endedSeptember 30, 2017;

• $11.7 million for the repurchase of a portion of our common units during the six months endedSeptember 30, 2017; and

• $10.5 million for the repurchase of warrants related to our Class A Preferred Units during the six months endedSeptember 30, 2017.

These decreases in net cash provided by financing activities were partially offset by a $25.8 million release of contingent consideration liabilities related to the termination of a development agreement during the six months endedSeptember 30, 2016.

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 September 18, 2017, the board of directors of our general partner declared a distribution for the three months endedSeptember 30, 2017 of $5.7 million, which was paid to the holders of the Class B Preferred Units on October 16, 2017.

On October 19, 2017, the board of directors of our general partner declared a distribution of $0.39 per common unit to the unitholders of record on November 6, 2017. In addition, the board of directors declared a distribution to the holders of the

77

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 November 14, 2017.

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 September 30, 2017. 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. See Note 9 to our unaudited condensed consolidated financial statements included in this Quarterly Report for additional information.

(3) At September 30, 2017, construction commitments primarily relate to the Glass Mountain pipeline extension.

(4) Index prices are based on a forward price curve at September 30, 2017. A theoretical change of $0.10 per gallon of natural gas liquids in the underlying commodity price at September 30, 2017 would result in a change of $67.0 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 September 30, 2017 would result in a change of $39.1 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.

78

(5) 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.

Environmental Legislation

See our Annual Report for a discussion of proposed environmental legislation and regulations that, if enacted, could result in increased compliance and operating costs. However, at this time we cannot predict the structure or outcome of any future legislation or regulations or the eventual cost we could incur in compliance.

Recent Accounting Pronouncements

For a discussion of recent accounting pronouncements that are applicable to us, see Note 2 to our unaudited condensed consolidated financial statements included in this Quarterly Report.

Critical Accounting Policies

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.

79

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.AtSeptember 30, 2017, we had$971.5 millionof outstanding borrowings under our Revolving Credit Facility at a weighted average interest rate of4.50%. A change in interest rates of 0.125% would result in an increase or decrease of our annual interest expense of $1.2 million, based on borrowings outstanding at September 30, 2017.

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 risk policy, respectively.Open commodity positions and market price changes are monitored daily and are reported to senior management and to marketing operations personnel.Credit risk is monitored daily and exposure is minimized through customer deposits, restrictions on product liftings, letters of credit, and entering into master netting agreements that allow for offsetting counterparty receivable and payable balances for certain transactions.AtSeptember 30, 2017, 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 September 30, 2017 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)	$	(5,451	)
Propane (Liquids segment)	$	1,404
Other products (Liquids segment)	$	(14,458	)
Gasoline (Refined Products and Renewables segment)	$	(15,196	)
Diesel (Refined Products and Renewables segment)	$	(4,990	)
Ethanol (Refined Products and Renewables segment)	$	(2,753	)
Biodiesel (Refined Products and Renewables segment)	$	124
Canadian dollars (Liquids segment)	$	711

80

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 the 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 September 30, 2017. Based on this evaluation, the principal executive officer and principal financial officer of our general partner have concluded that as of September 30, 2017, 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 endedSeptember 30, 2017 that have materially affected, or are reasonably likely to materially affect, our internal controls over financial reporting.

81

PART II - OTHER INFORMATION

Item 1.Legal Proceedings

We are involved from time to time in various legal proceedings and claims arising in the ordinary course of business. For information related to legal proceedings, see the discussion under the captions “Legal Contingencies” and “Environmental Matters” in Note 9 to our unaudited condensed consolidated financial statements included in this Quarterly Report, which information is incorporated by reference into this Item 1.

Item 1A.Risk Factors

There have been no material changes in the risk factors previously disclosed in Part I, Item 1A–“Risk Factors” in our Annual Report on Form 10-K for the fiscal year ended March 31, 2017, as supplemented and updated by Part II, Item 1A–“Risk Factors” in our Quarterly Report on Form 10-Q for the quarter ended June 30, 2017.

Item 2.Unregistered Sales of Equity Securities and Use of Proceeds

Common Unit Repurchase Program

On August 29, 2017, the board of directors of our general partner authorized a common unit repurchase program, under which we may repurchase up to $15.0 million of our outstanding common units through December 31,2017 from time to time in the open market or in other privately negotiated transactions. The common unit repurchase program authorization does not obligate us to repurchase any dollar amount or number of our common units. The following table summarizes the repurchase of common units during the three months endedSeptember 30, 2017:

				Total Number of
				Common Units	Approximate Dollar Value
	Total Number of	Average Price		Purchased as Part	of Common Units
	Common Units	Paid Per		of Publicly Announced	that May Yet Be Purchased
Period	Purchased	Common Unit		Program	Under the Program
July 1-31, 2017	37,554	$	13.58	—	$	—
August 1-31, 2017	227,192	$	9.00	227,192	$	12,948,047
September 1-30, 2017	966,443	$	9.39	966,443	$	3,847,062
Total	1,231,189			1,193,635	$	3,847,062

The common units not repurchased under the publicly announced program were surrendered by employees to pay tax withholding in connection with the vesting of restricted common units. As a result, we are including the common units surrendered in the Total Number of Common Units Purchased column.

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 cannot 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 and results of operations 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, 2017 was derived from our audited consolidated financial statements for the fiscal year ended March 31, 2017 included in our Annual Report on Form 10-K (“Annual Report”) filed with the SEC on May 26, 2017.

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, 2018.

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 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, and accruals for environmental matters. 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 risk policy, respectively.Open commodity positions and market price changes are monitored daily and are reported to senior management and to marketing operations personnel.Credit risk is monitored daily and exposure is minimized through customer deposits, restrictions on product liftings, letters of credit, and entering into master netting agreements that allow for offsetting counterparty receivable and payable balances for certain transactions.

Revenue Recognition

We record product sales revenues when title to the product transfers to the purchaser, which typically occurs when the purchaser receives the product. We record terminaling, transportation, storage, and service revenues when the service is performed, and we record tank and other rental revenues over the lease term. Revenues for our Water Solutions segment are recognized when we obtain the wastewater at our treatment and disposal facilities.

The tariffs we charge for our pipeline transportation systems are primarily regulated by the Federal Energy Regulatory Commission. Our tariffs include provisions which allow us to deduct from our customer’s inventory a small percentage of the products our customers transport on our pipeline systems. We refer to these product quantities as pipeline loss allowance. We receive pipeline loss allowances from our customers as consideration for product losses during the transportation of their products on our pipeline systems. Our customers are guaranteed delivery of the amount of their injected volumes, net of pipeline loss allowance, irrespective of what our actual product losses may be during the delivery process.

We report taxes collected from customers and remitted to taxing authorities, such as sales and use taxes, on a net basis. We include amounts billed to customers for shipping and handling costs in revenues in our unaudited condensed consolidated statements of operations. We enter into certain contracts whereby we agree to purchase product from a counterparty and sell the same volume of product to the same counterparty at a different location or time. When such agreements are entered into at the same time and in contemplation of each other, we record the revenues for these transactions net of cost of sales.

Revenues during the three months endedSeptember 30, 2017 and 2016 include $0.3 million and $1.2 million, respectively, and revenues during the six months endedSeptember 30, 2017 and 2016 include $0.7 million and $2.5 million, respectively, associated with the amortization of a liability recorded in the acquisition accounting for an acquired business related to certain out-of-market revenue contracts.

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 the United States and 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 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 consolidated financial statements. We had no material uncertain tax positions that required recognition in our unaudited condensed consolidated financial statements at September 30, 2017 or March 31, 2017.

Inventories

We value our inventories at the lower of cost or market, with cost determined using either the weighted-average cost or the first in, first out (FIFO) methods, including the cost of transportation and storage. Market is determined based on estimated replacement cost using prices at the end of the reporting period. On April 1, 2017, we adopted the new inventory standard, Accounting Standards Update (“ASU”) No. 2015-11. Under this ASU, inventory is to be measured at the lower of cost or net realizable value, which is defined as the estimated selling price in the ordinary course of business, less reasonable predictable costs of completion, disposal, and transportation. In performing this analysis, we consider fixed-price forward commitments and the opportunity to transfer propane inventory from our wholesale Liquids business to our Retail Propane business to sell the inventory in retail markets.

Inventories consist of the following at the dates indicated:

	September 30, 2017		March 31, 2017
	(in thousands)
Crude oil	$	81,969	$	146,857
Natural gas liquids:
Propane	107,364		38,631
Butane	93,257		5,992
Other	9,389		6,035
Refined products:
Gasoline	131,640		193,051
Diesel	90,696		98,237
Renewables:
Ethanol	31,273		42,009
Biodiesel	16,517		21,410
Other	8,628		9,210
Total	$	570,733	$	561,432

Investments in Unconsolidated Entities

Investments we cannot 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 historical net book value of the net assets of the investee. We use the cumulative earnings approach to classify distributions received from unconsolidated entities as either operating activities or investing activities in our unaudited condensed consolidated statements of cash flows.

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

Entity	Segment	Ownership Interest (1)	Date Acquired or Formed	September 30, 2017		March 31, 2017
				(in thousands)
Glass Mountain Pipeline, LLC (2)	Crude Oil Logistics	50%	December 2013	$	181,982	$	172,098
E Energy Adams, LLC	Refined Products and Renewables	19%	December 2013	14,264		12,952
Water treatment and disposal facility (3)	Water Solutions	50%	August 2015	2,035		2,147
Victory Propane, LLC (4)	Retail Propane	50%	April 2015	—		226
Total				$	198,281	$	187,423

(1) Ownership interest percentages are at September 30, 2017.

(2) Our investment in Glass Mountain Pipeline, LLC (“Glass Mountain”) exceeds our proportionate share of the historical net book value of Glass Mountain’s net assets by $71.5 million at September 30, 2017. This difference relates primarily to goodwill and customer relationships. We amortize the value of the customer relationships and record the expense within equity in earnings of unconsolidated entities in our unaudited condensed consolidated statement of operations.

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

(4) This investment is negative at September 30, 2017 and has been reclassified to current liabilities within our unaudited condensed consolidated balance sheet as we believe the decline to be temporary.

Other Noncurrent Assets

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

	September 30, 2017		March 31, 2017
	(in thousands)
Loan receivable (1)	$	35,242	$	40,684
Line fill (2)	30,628		30,628
Tank bottoms (3)	42,044		42,044
Minimum shipping fees - pipeline commitments (4)	76,619		67,996
Other	56,028		58,252
Total	$	240,561	$	239,604

(1) Represents 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 crude oil we are required to leave on certain third-party owned pipelines under long-term shipment commitments. At September 30, 2017 and March 31, 2017, line fill consisted of 427,193 barrels and 427,193 barrels of crude oil, respectively. 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 September 30, 2017 and March 31, 2017, tank bottoms held in third party terminals consisted of 366,212 barrels and 366,212 barrels of refined products, respectively. Tank bottoms held in terminals we own are included within property, plant and equipment (see Note 5).

(4) Represents the minimum shipping fees paid in excess of volumes shipped for two contracts. This amount can be recovered when volumes shipped exceed the minimum monthly volume commitment (see Note 9). Under these contracts, we currently have 2.6 years and 3.0 years, respectively, in which to ship the excess volumes.

Accrued Expenses and Other Payables

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

	September 30, 2017		March 31, 2017
	(in thousands)
Accrued compensation and benefits	$	23,083	$	22,227
Excise and other tax liabilities	56,562		64,051
Derivative liabilities	28,942		27,622
Accrued interest	41,916		44,418
Product exchange liabilities	25,869		1,693
Deferred gain on sale of general partner interest in TLP	30,113		30,113
Other	20,584		17,001
Total	$	227,069	$	207,125

Deferred Gain on Sale of General Partner Interest in TLP

On February 1, 2016, we sold our general partner interest in TransMontaigne Partners L.P. (“TLP”) to an affiliate of ArcLight Capital Partners. We deferred a portion of the gain on the sale and will recognize this amount over our future lease payment obligations, which is approximately seven years. During the three months endedSeptember 30, 2017 and 2016, we recognized $7.5 million and $7.5 million, respectively, and during the six months endedSeptember 30, 2017 and 2016, we recognized $15.1 million and $15.1 million, respectively, of the deferred gain in our unaudited condensed consolidated statements of operations. Within our September 30, 2017 unaudited condensed consolidated balance sheet, the current portion of the deferred gain, $30.1 million, is recorded in accrued expenses and other payables, and the long-term portion, $124.2 million, is recorded in other noncurrent liabilities.

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. During the six months endedSeptember 30, 2017, we recorded $0.7 million to adjust the redeemable noncontrolling interest to its maximum redemption value.

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 six months endedSeptember 30, 2017 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, 2017.

Reclassifications

We have reclassified certain prior period financial statement information to be consistent with the classification methods used in the current fiscal year. These reclassifications did not impact previously reported amounts of equity, net income, or cash flows. Also, certain line items in our unaudited condensed consolidated statement of cash flows were combined and the prior period amounts were combined to be consistent with the classification methods used in the current fiscal year.

Recent Accounting Pronouncements

In August 2016, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2016-15, “Statement of Cash Flows-Classification of Certain Cash Receipts and Cash Payments.” The ASU requires cash payments not made soon after the acquisition date of a business combination by an acquirer to settle a contingent consideration liability to be separated and classified as cash outflows for financing activities and operating activities. Cash payments up to the amount of the contingent consideration liability recognized at the acquisition date (including measurement-period adjustments) should be classified as financing activities and any excess should be classified as operating activities. We adopted this ASU effective April 1, 2017 and have revised previously reported information.

In June 2016, the FASB issued ASU No. 2016-13, “Financial Instruments-Credit Losses.” The ASU requires a financial asset (or a group of 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.

In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers.” The ASU will replace most existing revenue recognition guidance in GAAP. The core principle of this ASU is that an entity should recognize revenue for the transfer of goods or services equal to the amount that it expects to be entitled to receive for those goods or services. The ASU is effective for the Partnership beginning April 1, 2018, and allows for both full retrospective and modified retrospective methods of adoption.

We are in the process of evaluating our revenue contracts by segment and type to determine the potential impact of adopting this ASU. At this point in our evaluation process, we have determined that the timing and/or amount of revenue that we recognize on certain contracts, particularly contracts with minimum volume commitments, tiered pricing, non-cash consideration and multi-year services arrangements, may be impacted by the adoption of this ASU; however, we are still in the process of quantifying these impacts and have not yet determined whether they would be material to our consolidated financial statements. In addition, we are in the process of implementing appropriate changes to our business processes, systems and controls to support recognition and disclosure under this ASU. We continue to monitor additional authoritative or interpretive guidance related to this ASU as it becomes available, as well as comparing our conclusions on specific interpretative issues to other peers in our industry, to the extent that such information is available to us. We currently anticipate utilizing a modified retrospective adoption as of April 1, 2018.

Business Combinations [Abstract]

Acquisitions

Acquisitions

The following summarizes our acquisitions during the six months endedSeptember 30, 2017:

Acquisition of Remaining Interest in NGL Solids Solutions, LLC

On April 17, 2017, we entered into a purchase and sale agreement with the party owning the 50% noncontrolling interest in NGL Solids Solutions, LLC, a consolidated subsidiary, in our Water Solutions segment. Total consideration was $23.1 million, which consisted of cash of $20.0 million and the termination of a non-compete agreement that we valued at $3.1 million and in return we received the following:

• The remaining 50% interest in NGL Solids Solutions, LLC; and

• Two parcels of land to develop saltwater disposal wells.

We accounted for the transaction as an acquisition of assets. Acquiring assets in groups requires not only ascertaining the cost of the asset (or net asset) group but also allocating that cost to the individual assets (or individual assets and liabilities) that make up the group. The cost of a group of assets acquired in an asset acquisition is allocated to the individual assets acquired or liabilities assumed/released based on their relative fair values and does not give rise to goodwill or bargain purchase gains. We allocated $22.9 million to noncontrolling interest and $0.2 million to land. 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 50% noncontrolling interest had a carrying value of $16.6 million. For the termination of the non-compete agreement, we recorded a gain of $1.3 million, which included the carrying value of the non-compete agreement intangible asset that was written off (see Note 7). This gain was recorded within loss (gain) on disposal or impairment of assets, net in our unaudited condensed consolidated statement of operations during the six months endedSeptember 30, 2017.

Retail Propane Businesses

During the six months endedSeptember 30, 2017, we acquired four retail propane businesses for total consideration of $29.3 million. The agreements for these acquisitions contemplate post-closing payments for certain working capital items.

We are in the process of identifying and determining the fair values of the assets acquired and liabilities assumed for these retail propane businesses, and as a result, the estimates of fair value at September 30, 2017 are subject to change. The following table summarizes the preliminary estimates of the fair values of the assets acquired and liabilities assumed (in thousands):

Current assets	$	1,880
Property, plant and equipment	10,051
Goodwill	4,150
Intangible assets	14,875
Current liabilities	(1,484		)
Other noncurrent liabilities	(134		)
Fair value of net assets acquired	$	29,338

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 acquire the skilled workforce of each of the businesses acquired and the ability to expand into new markets. We expect that all of the goodwill will be deductible for federal income tax purposes.

The operations of these retail propane businesses have been included in our unaudited condensed consolidated statement of operations since their acquisition date. Our unaudited condensed consolidated statement of operations for the six months endedSeptember 30, 2017 includes revenues of $2.8 million and operating income of less than $0.1 million that were generated by the operations of two of these retail propane businesses. The revenues and operating income of the other retail propane business acquisitions are not considered material.

The following summarizes the status of the preliminary purchase price allocation of acquisitions prior to April 1, 2017:

Water Solutions Facilities

During the six months ended September 30, 2017, we completed the acquisition accounting for two water solutions facilities. During the six months ended September 30, 2017, we received additional information and recorded a decrease of $0.2 million to property, plant and equipment and an increase of less than $0.1 million to other noncurrent liabilities related to an asset retirement obligation. The offset of these adjustments was recorded to goodwill.

Retail Propane Businesses

During the six months ended September 30, 2017, we completed the acquisition accounting for three retail propane businesses. During the six months ended September 30, 2017, we received additional information and recorded a decrease of $0.2 million to current assets and a decrease of less than $0.1 million to property, plant and equipment. The offset of these adjustments was recorded to goodwill. In addition, we paid $0.4 million in cash to the sellers during the six months ended September 30, 2017 for consideration that was held back at the acquisition date, which we recorded as a liability within accrued expenses and other payables in our unaudited condensed consolidated balance sheet.

Natural Gas Liquids Facilities

During the three months ended June 30, 2017, we completed the acquisition accounting for certain natural gas liquids facilities acquired in January 2017. There were no material adjustments to the fair value of assets acquired and liabilities assumed during the three months ended June 30, 2017.

We record losses (gains) from the sales of property, plant and equipment and any write-downs in value due to impairment within loss (gain) on disposal or impairment of assets, net in our unaudited condensed consolidated statements of operations. During the three months endedSeptember 30, 2017, we recorded a net loss of $1.9 million, of which $0.4 million related to a gain on the sale of excess pipe in our Crude Oil Logistics segment. During the six months endedSeptember 30, 2017, we recorded a net gain of $0.6 million, of which $3.8 million related to the gain on the sale of excess pipe in our Crude Oil Logistics segment. The gain was partially offset by losses from the sale of certain assets and the write down of certain other assets.

Goodwill Impairment

Due to the decreased demand for natural gas liquid storage and resulting decline in revenues and earnings as compared to actual and projected results of prior and future periods, we tested the goodwill within our natural gas liquids salt cavern storage reporting unit (“Sawtooth reporting unit”), which is part of our Liquids segment, for impairment at September 30, 2017. We estimated the fair value of our Sawtooth reporting unit based on the income approach, also known as the discounted cash flow method, which utilizes the present value of future expected cash flows to estimate the fair value. The future cash flows of our Sawtooth reporting unit were projected based upon estimates as of the test date of future revenues, operating expenses and cash outflows necessary to support these cash flows, including working capital and maintenance capital expenditures. We also considered expectations regarding: (i) expected storage volumes, which are assumed to increase in the coming years due to increased production of natural gas liquids, (ii) expected propane and butane prices and (iii) expected rental fees. We assumed a 2% per year increase in commodity prices and a 4% increase in rental fees per year starting in April 2018, and held such prices and fees flat for periods in our model beyond our 2023 fiscal year. For expenses, we assumed an increase consistent with the increase in storage volumes, and maintenance capital was held flat throughout the model. The discount rate used in our discounted cash flow method was a risk adjusted weighted average cost of capital calculated as of September 30, 2017 of 12%. The discounted cash flow results indicated that the estimated fair value of our Sawtooth reporting unit was less than its carrying value by approximately 32% at September 30, 2017.

During the three months ended September 30, 2017, we recorded a goodwill impairment charge of $116.9 million, which was recorded within loss (gain) on disposal or impairment of assets, net, in our unaudited condensed consolidated statement of operations. At September 30, 2017, our Sawtooth reporting unit had a goodwill balance of $66.2 million.

Our estimated fair value is predicated upon management’s assumption of the growth in the production of natural gas liquids and the decline in the use of railcars to store natural gas liquids. We used these assumptions to estimate the demand for storage at our facility and the revenue generated by customers reserving capacity at our facility. Due to the current volatility in commodity prices and the excess railcars currently in the market, we believe it is reasonably possible that the need for underground storage we estimate in our model does not materialize, such that our estimate of fair value could change and result in further impairment of the goodwill in our Sawtooth reporting unit.

Credit Agreement

We are party to a $1.765 billion credit agreement (the “Credit Agreement”) with a syndicate of banks. As of September 30, 2017, the Credit Agreement includes a revolving credit facility to fund working capital needs, which had a capacity of $1.05 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 $715.0 million (the “Expansion Capital Facility,” and together with the Working Capital Facility, the “Revolving Credit Facility”). During the three months endedSeptember 30, 2017, we reallocated $50.0 million from the Expansion Capital Facility to the Working Capital Facility. We had letters of credit of $115.1 million on the Working Capital Facility at September 30, 2017.

At September 30, 2017, the borrowings under the Credit Agreement had a weighted average interest rate of 4.50%, calculated as the weighted average LIBOR rate of 1.24% plus a margin of 3.00% for LIBOR borrowings and the prime rate of 4.25% plus a margin of 2.00% on alternate base rate borrowings. At September 30, 2017, the interest rate in effect on letters of credit was 3.00%. Commitment fees were charged at a rate ranging from 0.375% to 0.50% on any unused capacity.

On June 2, 2017, we amended our Credit Agreement. The amendment, among other things, restricts us from increasing our distribution rate over the amount paid in the preceding quarter if our leverage ratio is greater than 4.25 to 1. The following table summarizes the debt covenant levels specified in the Credit Agreement as of September 30, 2017:

		Senior Secured	Interest
Period Beginning	Leverage Ratio (1)	Leverage Ratio (1)	Coverage Ratio (2)
September 30, 2017	5.50	2.50	2.25
March 31, 2018	4.75	3.25	2.75
March 31, 2019 and thereafter	4.50	3.25	2.75

(1) Amount represents the maximum ratio for the period presented.

(2) Amount represents the minimum ratio for the period presented.

At September 30, 2017 our leverage ratio was approximately 5.42 to 1, our senior secured leverage ratio was approximately 0.75 to 1 and our interest coverage ratio was approximately 2.26 to 1.

At September 30, 2017, we were in compliance with the covenants under the Credit Agreement.

Senior Secured Notes

During the six months endedSeptember 30, 2017, we repurchased $55.0 million of our senior secured notes for an aggregate purchase price of $57.2 million (excluding payments of accrued interest), and recorded a loss on the early extinguishment of $3.2 million (net of $1.0 million of debt issuance costs.) Following the repurchase, semi-annual installment payments will be $19.5 million beginning on December 19, 2017 and ending on the maturity date of June 19, 2022.

On August 2, 2017, we amended the note purchase agreement for our senior secured notes with an effective date of June 2, 2017. The amendment, among other things, conforms the financial covenants to match the amended terms of the Credit Agreement and provides for an increase in interest charged if our leverage ratio exceeds certain predetermined levels.In addition, the amendment also restricts us from increasing our distribution rate over the amount paid in the preceding quarter if our interest coverage ratio is less than 3.00 to 1.

At September 30, 2017, we were in compliance with the covenants under the note purchase agreement for our senior secured notes.

Senior Unsecured Notes

Registration Rights

In connection with the issuance of the 7.50% senior notes due 2023 (the “2023 Notes”) and the 6.125% senior notes due 2025 (the “2025 Notes”), we entered into a registration rights agreement in which we agreed to file a registration statement with the SEC so that the holders can exchange the 2023 Notes and the 2025 Notes for registered notes that have substantially identical terms as the 2023 Notes and the 2025 Notes and evidence the same indebtedness of the 2023 Notes and the 2025 Notes. In addition, the subsidiary guarantors agreed to exchange the guarantee related to the 2023 Notes and the 2025 Notes for a registered guarantee having substantially the same terms as the original guarantee. We filed a registration statement for both the 2023 Notes and the 2025 Notes with the SEC which became effective on July 11, 2017 and 99.98% of the 2023 Notes and 99.98% of the 2025 Notes were exchanged on August 8, 2017.

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingencies

Legal Contingencies

We are party to various claims, legal actions, and complaints arising in the ordinary course of business. In the opinion of our management, the ultimate resolution of these 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

Our unaudited condensed consolidated balance sheet at September 30, 2017 includes a liability, measured on an undiscounted basis, of $2.1 million related to environmental matters, 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.

As previously disclosed, the U.S. Environmental Protection Agency (“EPA”) had informed NGL Crude Logistics, LLC, formerly known as Gavilon, LLC (“Gavilon Energy”), of alleged violations in 2011 by Gavilon Energy of the Clean Air Act’s renewable fuel standards regulations (prior to its 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, which was denied on May 24, 2017. On October 17, 2017, the EPA filed a motion for partial summary judgment against Gavilon Energy. Consistent with our position against the previous EPA allegations, we deny the allegations in the amended civil complaint and that the EPA is entitled to summary judgment and we intend to continue vigorously defending ourselves in the civil action. However, at this time we are unable to determine the outcome of this action or its significance to us.

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, 2017	$	8,181
Liabilities incurred	422
Liabilities assumed in acquisitions	21
Liabilities settled	(233		)
Accretion expense	511
Balance at September 30, 2017	$	8,902

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 September 30, 2017 (in thousands):

Fiscal Year Ending March 31,
2018 (six months)	$	71,787
2019	120,589
2020	107,255
2021	94,118
2022	65,985
Thereafter	93,844
Total	$	553,578

Rental expense relating to operating leases was $32.5 million and $27.0 million during the three months endedSeptember 30, 2017 and 2016, respectively, and $63.8 million and $56.9 million during the six months endedSeptember 30,2017 and 2016, respectively.

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. We currently have an asset recorded in other noncurrent assets in our unaudited condensed consolidated balance sheet for minimum shipping fees paid in 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 September 30, 2017 (in thousands):

Fiscal Year Ending March 31,
2018 (six months)	$	26,001
2019	52,042
2020	42,351
Total	$	120,394

Construction Commitments

At September 30, 2017, we had construction commitments of $24.5 million.

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 September 30, 2017, 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:

Total	$	1,770,080	39,142	$	601,243	669,811

(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 September 30, 2017, 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:
2018 (six months)	$	204,579	4,196	$	137,467	159,427

Total	$	629,095	12,402	$	528,593	485,281

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 $28.1 million of our prepaid expenses and other current assets and $28.2 million of our accrued expenses and other payables at September 30, 2017.

Equity

6 Months Ended

Sep. 30, 2017

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 converted to common units during the six months endedSeptember 30, 2017, we issued 333 notional units to our general partner for less than $0.1 million in order to maintain its 0.1% interest in us.

Common Unit Repurchase Program

On August 29, 2017, the board of directors of our general partner authorized a common unit repurchase program, under which we may repurchase up to $15.0 million of our outstanding common units through December 31, 2017from time to time in the open market or in other privately negotiated transactions. During the three months endedSeptember 30, 2017, we repurchased 1,193,635common units for an aggregate price of $11.2 million, including commissions.

Our Distributions

The following table summarizes distributions declared on our common units during the last three 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, 2017	May 8, 2017	May 15, 2017	$	0.3900	$	46,870	$	80
July 20, 2017	August 4, 2017	August 14, 2017	$	0.3900	$	47,460	$	81
October 19, 2017	November 6, 2017	November 14, 2017	$	0.3900	$	47,000	$	81

Class A Convertible Preferred Units

On April 21, 2016, we received net proceeds $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 the warrants. Accretion for the beneficial conversion feature, recorded as a deemed distribution, was $4.0 million and $2.2 million during the three months endedSeptember 30, 2017 and 2016, respectively, and $7.2 million and $3.8 million during the six months endedSeptember 30, 2017 and 2016, respectively.

The holders of the warrants may convert 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. During the six months endedSeptember 30, 2017, 607,653 warrants were converted to common units and we received proceeds of less than $0.1 million. In addition, we repurchased 850,716 unvested warrants for a total purchase price of $10.5 million on June 23, 2017. As of September 30, 2017, we had 2,916,743 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 three quarters:

		Amount Paid/Payable to Class A
Date Declared	Date Paid/Payable	Preferred Unitholders
		(in thousands)
April 24, 2017	May 15, 2017	$	6,449
July 20, 2017	August 14, 2017	$	6,449
October 19, 2017	November 14, 2017	$	6,449

Class B Preferred Units

During the six months endedSeptember 30, 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 $202.8 million (net of the underwriters’ discount of $6.6 million and offering costs of $0.6 million).

At any time on or after July 1, 2022, we may redeem our Class B Preferred Units, in whole or in part, at a redemption price of $25.00 per Class B Preferred Unit plus an amount equal to all accumulated and unpaid distributions to, but not including, the date of redemption, whether or not declared. We may also redeem the Class B Preferred Units upon a change of control as defined in our partnership agreement. If we choose not to redeem the Class B Preferred Units, the Class B preferred unitholders may have the ability to convert the Class B Preferred Units to common units at the then applicable conversion rate. Class B preferred unitholders have no voting rights except with respect to certain matters set forth in our partnership agreement.

Distributions on the Class B Preferred Units are payable on the 15th day of each January, April, July and October of each year (beginning on October 15, 2017) to holders of record on the first day of each payment month. The initial distribution rate for the Class B Preferred Units from and including the date of original issue to, but not including, July 1, 2022 is 9.00% per year of the $25.00 liquidation preference per unit (equal to $2.25 per unit per year). On and after July 1, 2022, distributions on the Class B Preferred Units will accumulate at a percentage of the $25.00 liquidation preference equal to the applicable three-month LIBOR plus a spread of 7.213%. On September 18, 2017, the board of directors of our general partner declared a distribution for the three months endedSeptember 30, 2017 of $5.7 million, for which the amount is included in accrued expenses and other payables in our unaudited condensed consolidated balance sheet at September 30, 2017. The distribution was paid to the holders of the Class B Preferred Units on October 16, 2017.

Amended and Restated Partnership Agreement

On June 13, 2017, NGL Energy Holdings LLC executed the Fourth Amended and Restated Agreement of Limited Partnership. The preferences, rights, powers and duties of holders of the Class B Preferred Units are defined in the amended and restated partnership agreement. The Class B Preferred Units rank senior to the common units, with respect to the payment of distributions and distribution of assets upon liquidation, dissolution and winding up and are on parity with the Class A Preferred Units. The Class B Preferred Units have no stated maturity but we may redeem the Class B Preferred Units at any time on or after July 1, 2022. Upon the occurrence of a change in control, we may redeem the Class B Preferred Units.

At-The-Market Program

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 six months endedSeptember 30, 2017, and approximately $134.7 million remained available for sale under the ATM Program at September 30, 2017.

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”).

On April 1, 2017, we made an accounting policy election to account for actual forfeitures, rather than estimate forfeitures each period (as previously required). As a result, the cumulative effect adjustment, which represents the differential between the amount of compensation expense previously recorded and the amount that would have been recorded without assuming forfeitures, had no impact on our consolidated financial statements.

The following table summarizes the Service Award activity during the six months endedSeptember 30, 2017:

Unvested Service Award units at March 31, 2017	2,708,500
Units granted	137,921
Units vested and issued	(956,821	)
Units forfeited	(51,300	)
Unvested Service Award units at September 30, 2017	1,838,300

In connection with the vesting of certain restricted units during the six months endedSeptember 30, 2017, we canceled 37,554 of the newly-vested common units in satisfaction of $0.5 million of employee tax liability paid by us. Pursuant to the terms of the LTIP, these canceled units are available for future grants under the LTIP.

The following table summarizes the scheduled vesting of our unvested Service Award units at September 30, 2017:

Fiscal Year Ending March 31,
2018 (six months)	—
2019	919,350
2020	914,450
2021	4,500
Total	1,838,300

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 endedSeptember 30, 2017 and 2016, we recorded compensation expense related to Service Award units of $3.3 million and $25.8 million, respectively. During the six months endedSeptember 30, 2017 and 2016, we recorded compensation expense related to Service Award units of $8.6 million and $46.7 million, respectively.

Of the restricted units granted and vested during the six months endedSeptember 30, 2017, 66,421 units were granted as a bonus for performance during the fiscal year ended March 31, 2017. We accrued expense of $0.9 million during the fiscal year ended March 31, 2017 as an estimate of the value of such bonus units that would be granted.

The following table summarizes the estimated future expense we expect to record on the unvested Service Award units at September 30, 2017 (in thousands):

Fiscal Year Ending March 31,
2018 (six months)	$	5,865
2019	10,697
2020	2,827
2021	13
Total	$	19,402

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 September 30, 2017, 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

The following table summarizes the Performance Award activity during the six months endedSeptember 30, 2017:

Unvested Performance Award units at March 31, 2017	1,189,000
Units forfeited	(404,000	)
Unvested Performance Award units at September 30, 2017	785,000

During the July 1, 2014 through June 30, 2017 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, 2017 and performance units with the July 1, 2017 vesting date are considered to 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 endedSeptember 30, 2017 and 2016, we recorded compensation expense related to Performance Award units of $1.3 million and $1.6 million, respectively. During the six months endedSeptember 30, 2017 and 2016, we recorded compensation expense related to Performance Awards units of $3.4 million and $3.1 million, respectively.

The following table summarizes the estimated future expense we expect to record on the unvested Performance Award units at September 30, 2017 (in thousands):

Fiscal Year Ending March 31,
2018 (six months)	$	2,635
2019	3,167
2020	642
Total	$	6,444

At September 30, 2017, approximately 3.2 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.

During the three months and six months endedSeptember 30, 2017, we recorded a net loss of $71.4 million and $34.9 million, respectively, and during the three months and six months endedSeptember 30, 2016, we recorded a net gain of $14.7 million and a net loss of $45.0 million, respectively, 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. AtSeptember 30, 2017, 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.AtSeptember 30, 2017, we had$971.5 millionof outstanding borrowings under our Revolving Credit Facility at a weighted average interest rate of4.50%.

Fair Value of Fixed-Rate Notes

The following table provides fair value estimates of our fixed-rate notes at September 30, 2017 (in thousands):

Senior secured notes	$	201,715
Senior unsecured notes:
5.125% Notes due 2019	$	360,673
6.875% Notes due 2021	$	366,938
7.500% Notes due 2023	$	670,605
6.125% Notes due 2025	$	451,004

For the senior secured notes, the fair value estimate was developed using observed yields on publicly traded notes issued by us, adjusted for differences in the key terms of those notes and the key terms of our notes (examples include differences in the tenor of the debt, credit standing of the issuer, whether the notes are publicly traded, and whether the notes are secured or unsecured). This fair value estimate would be classified as Level 3 in the fair value hierarchy. 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.

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.

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 cannot 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 and results of operations 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, 2017 was derived from our audited consolidated financial statements for the fiscal year ended March 31, 2017 included in our Annual Report on Form 10-K (“Annual Report”) filed with the SEC on May 26, 2017.

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, 2018.

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 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, and accruals for environmental matters. 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 risk policy, respectively.Open commodity positions and market price changes are monitored daily and are reported to senior management and to marketing operations personnel.Credit risk is monitored daily and exposure is minimized through customer deposits, restrictions on product liftings, letters of credit, and entering into master netting agreements that allow for offsetting counterparty receivable and payable balances for certain transactions.

Revenue Recognition

Revenue Recognition

We record product sales revenues when title to the product transfers to the purchaser, which typically occurs when the purchaser receives the product. We record terminaling, transportation, storage, and service revenues when the service is performed, and we record tank and other rental revenues over the lease term. Revenues for our Water Solutions segment are recognized when we obtain the wastewater at our treatment and disposal facilities.

The tariffs we charge for our pipeline transportation systems are primarily regulated by the Federal Energy Regulatory Commission. Our tariffs include provisions which allow us to deduct from our customer’s inventory a small percentage of the products our customers transport on our pipeline systems. We refer to these product quantities as pipeline loss allowance. We receive pipeline loss allowances from our customers as consideration for product losses during the transportation of their products on our pipeline systems. Our customers are guaranteed delivery of the amount of their injected volumes, net of pipeline loss allowance, irrespective of what our actual product losses may be during the delivery process.

We report taxes collected from customers and remitted to taxing authorities, such as sales and use taxes, on a net basis. We include amounts billed to customers for shipping and handling costs in revenues in our unaudited condensed consolidated statements of operations. We enter into certain contracts whereby we agree to purchase product from a counterparty and sell the same volume of product to the same counterparty at a different location or time. When such agreements are entered into at the same time and in contemplation of each other, we record the revenues for these transactions net of cost of sales.

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 the United States and 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 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 consolidated financial statements.

Inventories

Inventories

We value our inventories at the lower of cost or market, with cost determined using either the weighted-average cost or the first in, first out (FIFO) methods, including the cost of transportation and storage. Market is determined based on estimated replacement cost using prices at the end of the reporting period. On April 1, 2017, we adopted the new inventory standard, Accounting Standards Update (“ASU”) No. 2015-11. Under this ASU, inventory is to be measured at the lower of cost or net realizable value, which is defined as the estimated selling price in the ordinary course of business, less reasonable predictable costs of completion, disposal, and transportation. In performing this analysis, we consider fixed-price forward commitments and the opportunity to transfer propane inventory from our wholesale Liquids business to our Retail Propane business to sell the inventory in retail markets.

Investments in Unconsolidated Entities

Investments in Unconsolidated Entities

Investments we cannot 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 historical net book value of the net assets of the investee. We use the cumulative earnings approach to classify distributions received from unconsolidated entities as either operating activities or investing activities in our unaudited condensed consolidated statements of cash flows.

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.

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 six months endedSeptember 30, 2017 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, 2017.

Reclassifications

Reclassifications

We have reclassified certain prior period financial statement information to be consistent with the classification methods used in the current fiscal year. These reclassifications did not impact previously reported amounts of equity, net income, or cash flows. Also, certain line items in our unaudited condensed consolidated statement of cash flows were combined and the prior period amounts were combined to be consistent with the classification methods used in the current fiscal year.

Recent Accounting Pronouncements

Recent Accounting Pronouncements

In August 2016, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2016-15, “Statement of Cash Flows-Classification of Certain Cash Receipts and Cash Payments.” The ASU requires cash payments not made soon after the acquisition date of a business combination by an acquirer to settle a contingent consideration liability to be separated and classified as cash outflows for financing activities and operating activities. Cash payments up to the amount of the contingent consideration liability recognized at the acquisition date (including measurement-period adjustments) should be classified as financing activities and any excess should be classified as operating activities. We adopted this ASU effective April 1, 2017 and have revised previously reported information.

In June 2016, the FASB issued ASU No. 2016-13, “Financial Instruments-Credit Losses.” The ASU requires a financial asset (or a group of 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.

In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers.” The ASU will replace most existing revenue recognition guidance in GAAP. The core principle of this ASU is that an entity should recognize revenue for the transfer of goods or services equal to the amount that it expects to be entitled to receive for those goods or services. The ASU is effective for the Partnership beginning April 1, 2018, and allows for both full retrospective and modified retrospective methods of adoption.

We are in the process of evaluating our revenue contracts by segment and type to determine the potential impact of adopting this ASU. At this point in our evaluation process, we have determined that the timing and/or amount of revenue that we recognize on certain contracts, particularly contracts with minimum volume commitments, tiered pricing, non-cash consideration and multi-year services arrangements, may be impacted by the adoption of this ASU; however, we are still in the process of quantifying these impacts and have not yet determined whether they would be material to our consolidated financial statements. In addition, we are in the process of implementing appropriate changes to our business processes, systems and controls to support recognition and disclosure under this ASU. We continue to monitor additional authoritative or interpretive guidance related to this ASU as it becomes available, as well as comparing our conclusions on specific interpretative issues to other peers in our industry, to the extent that such information is available to us. We currently anticipate utilizing a modified retrospective adoption as of April 1, 2018.

Equity (Policies)

Equity [Abstract]

Forfeitures

On April 1, 2017, we made an accounting policy election to account for actual forfeitures, rather than estimate forfeitures each period (as previously required). As a result, the cumulative effect adjustment, which represents the differential between the amount of compensation expense previously recorded and the amount that would have been recorded without assuming forfeitures, had no impact on our consolidated financial statements.

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.
