NOTES TO THE UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
 

(1) Summary of Significant Accounting Policies

Organization

Enable Midstream Partners, LP is a Delaware limited partnership whose assets and operations are organized into two reportable segments: (i) gathering and processing and (ii) transportation and storage. The gathering and processing segment primarily provides natural gas and crude oil gathering and natural gas processing services to our producer customers. The transportation and storage segment provides interstate and intrastate natural gas pipeline transportation and storage services primarily to our producer, power plant, LDC and industrial end-user customers. The Partnership’s natural gas gathering and processing assets are primarily located in Oklahoma, Texas, Arkansas and Louisiana and serve natural gas production in the Anadarko, Arkoma and Ark-La-Tex Basins. Crude oil gathering assets are located in Oklahoma and serve crude oil production in the SCOOP and STACK plays of the Anadarko Basin and in North Dakota and serve crude oil production in the Bakken Shale formation of the Williston Basin. The Partnership’s natural gas transportation and storage assets consist primarily of an interstate pipeline system extending from western Oklahoma and the Texas Panhandle to Louisiana, an interstate pipeline system extending from Louisiana to Illinois, an intrastate pipeline system in Oklahoma, and our investment in SESH, a pipeline extending from Louisiana to Alabama.

CenterPoint Energy and OGE Energy each have 50% of the management interests in Enable GP. Enable GP is the general partner of the Partnership and has no other operating activities. Enable GP is governed by a board made up of two representatives designated by each of CenterPoint Energy and OGE Energy, along with the Partnership’s Chief Executive Officer and three independent board members CenterPoint Energy and OGE Energy mutually agreed to appoint. CenterPoint Energy and OGE Energy also own a 40% and 60% interest, respectively, in the incentive distribution rights held by Enable GP.

As of September 30, 2020, CenterPoint Energy held approximately 53.7% or 233,856,623 of the Partnership’s common units, and OGE Energy held approximately 25.5% or 110,982,805 of the Partnership’s common units. Additionally, CenterPoint Energy holds 14,520,000 Series A Preferred Units. The limited partner interests of the Partnership have limited voting rights on matters affecting the business. As such, limited partners do not have rights to elect the Partnership’s general partner on an annual or continuing basis and may not remove Enable GP, its current general partner, without at least a 75% vote by all unitholders, including all units held by the Partnership’s limited partners, and Enable GP and its affiliates, voting together as a single class.

As of September 30, 2020, the Partnership owned a 50% interest in SESH. See Note 8 for further discussion of SESH. For the nine months ended September 30, 2020, the Partnership held a 50% ownership in Atoka and consolidated Atoka in its Condensed Consolidated Financial Statements as EOIT acted as the managing member of Atoka and had control over the operations of Atoka. In addition, the Partnership held a 60% interest in ESCP, which is consolidated in its Condensed Consolidated Financial Statements as EOCS acted as the managing member of ESCP and had control over the operations of ESCP.

Basis of Presentation

The accompanying Condensed Consolidated Financial Statements and related notes of the Partnership have been prepared pursuant to the rules and regulations of the SEC and GAAP. Pursuant to such rules and regulations, certain disclosures normally included in financial statements prepared in accordance with GAAP have been omitted. The accompanying Condensed Consolidated Financial Statements and related notes should be read in conjunction with the Consolidated Financial Statements and related notes included in our Annual Report.

The Condensed Consolidated Financial Statements and the related notes reflect all normal recurring adjustments that are, in the opinion of management, necessary to present fairly the financial position and results of operations for the respective periods. Amounts reported in the Partnership’s Condensed Consolidated Statements of Income are not necessarily indicative of amounts expected for a full-year period due to the effects of, among other things, (a) seasonal fluctuations in demand for energy and energy services, (b) changes in energy commodity prices, (c) timing of maintenance and other expenditures, (d) acquisitions and dispositions of businesses, assets and other interests, and (e) the impact of the ongoing COVID-19 pandemic and the economic effects of the pandemic which have resulted in a substantial decrease in natural gas, NGLs and crude oil prices.

Table of Contents
For a description of the Partnership’s reportable segments, see Note 16.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Sales and Retirements of Assets

On September 23, 2019, the Partnership entered into an agreement to sell its undivided 1/12th interest in the Bistineau Storage Facility in Louisiana for approximately $19 million. On January 27, 2020, FERC approved the sale. The Partnership closed the sale on April 1, 2020. We did not recognize a gain or loss on this transaction.

In April 2020, we sustained damage to an approximately 100-mile gas gathering system in the Ark-La-Tex Basin of our gathering and processing segment. We have ceased operation of this system and are in the process of retiring it. We recognized a loss on retirement of approximately $20 million during the nine months ended September 30, 2020, which is included in Operation and maintenance expense in the Condensed Consolidated Statements of Income.

Depreciation Expense

On March 26, 2020, FERC issued an order approving MRT’s 2018 Rate Case and 2019 Rate Case settlements. As a result of the settlements, the new depreciation rates for MRT have been applied in accordance with the order. The new depreciation rates did not result in a material change in depreciation expense or results of operations.

Accounts Receivable and Allowance for Doubtful Accounts

The Partnership adopted ASU No. 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” on January 1, 2020. Upon adoption, the Partnership recognized a $3 million cumulative adjustment to Partners’ Equity and a corresponding adjustment to Allowance for doubtful accounts.

Accounts receivable are recorded at the invoiced amount and do not typically bear interest. The determination of the allowance for doubtful accounts requires management to make estimates and judgments regarding our customers’ ability to pay. The allowance for doubtful accounts is determined based primarily upon the historical loss-rate method established for various pools of accounts receivables with similar levels of credit risk. The historical loss-rates are then adjusted, as necessary, based on current conditions and forecast information that could result in future uncollectable amounts. On an ongoing basis, we evaluate our customers’ financial strength and liquidity based on aging of accounts receivable, payment history, and review of other relevant information, including ratings agency credit ratings and alerts, publicly available reports and news releases, and bank and trade references. It is the policy of management to review the outstanding accounts receivable and other receivable balances within other assets at least quarterly, giving consideration to credit losses, the aging of receivables, specific customer circumstances that may impact their ability to pay the amounts due and current and forecast economic conditions over the assets contractual lives. The following table summarizes the required allowance for doubtful accounts.

Accounts receivable$2 $2 
Other assets3 3 
Total Allowance for doubtful accounts$5 $5 

Inventory

Natural gas inventory is held, through the transportation and storage segment, to provide operational support for pipeline deliveries and to manage leased intrastate storage capacity. Natural gas liquids inventory is held, through the gathering and processing segment, due to timing differences between the production of certain natural gas liquids and ultimate sale to third parties. Natural gas and natural gas liquids inventory is valued using moving average cost and is subsequently recorded at the lower of cost or net realizable value. The Partnership recorded write-downs to net realizable value related to natural gas and natural gas liquids inventory of $2 million and zero during the three months ended September 30, 2020 and 2019, respectively,

and $9 million and $6 million during the nine months ended September 30, 2020 and 2019, respectively.

Assessing Impairment of Property, Plant and Equipment, Goodwill and Investment in Equity Method Affiliate

The Partnership periodically evaluates long-lived assets, including property, plant and equipment, and specifically identifiable intangibles other than goodwill, when events or changes in circumstances indicate that the carrying value of these assets may not be recoverable. The determination of whether an impairment has occurred is based on an estimate of undiscounted cash flows attributable to the assets, as compared to the carrying value of the assets. For more information, see Note 7.

The Partnership assesses its goodwill for impairment annually on October 1st, or more frequently if events or changes in circumstances indicate that the carrying value of goodwill may not be recoverable. Goodwill is assessed for impairment by comparing the fair value of the reporting unit with its book value, including goodwill. The Partnership utilizes the market or income approaches to estimate the fair value of the reporting unit, also giving consideration to the alternative cost approach. Under the market approach, historical and current year forecasted cash flows are multiplied by a market multiple to determine fair value. Under the income approach, anticipated cash flows over a period of years plus a terminal value are discounted to present value using appropriate discount rates. The resulting fair value of the reporting unit is then compared to the carrying amount of the reporting unit and an impairment charge is recorded to goodwill for the difference. The Partnership performs its goodwill impairment testing at the reporting unit, which is one level below the transportation and storage and gathering and processing reportable segment level. For more information, see Note 7.

The Partnership evaluates its Investment in equity method affiliate for impairment when factors indicate that an other than temporary decrease in the value of its investment has occurred and the carrying amount of its investment may not be recoverable. The Partnership utilizes the market or income approaches to estimate the fair value of the investment, also giving consideration to the alternative cost approach. Under the market approach, historical and current year forecasted cash flows are multiplied by a market multiple to determine fair value. Under the income approach, anticipated cash flows over a period of years plus a terminal value are discounted to present value using appropriate discount rates. The resulting fair value of the investment is then compared to the carrying amount of the investment and an impairment charge is recorded to Equity in earnings (losses) of equity method affiliate, net for the difference. Any basis difference between our recognized Investment in equity method affiliate and the underlying financial statements of the affiliate are assigned to the applicable net assets of the affiliate. For more information, see Note 8.

In March 2020, the FASB issued ASU No. 2020-04, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting.” This standard provides optional guidance, for a limited time, to ease the potential burden in accounting for or recognizing the effects of reference rate reform on financial reporting. The standard was effective upon issuance and generally can be applied through December 31, 2022. The Partnership is currently evaluating the impact this ASU will have on our Condensed Consolidated Financial Statements and related disclosures.

MRT Rate Case Settlements

In June 2018, MRT filed a general NGA rate case (the 2018 Rate Case), and in October 2019, MRT filed a second rate case (the 2019 Rate Case). MRT began collecting the rates proposed in the 2018 Rate Case, subject to refund, on January 1, 2019. On March 26, 2020, FERC issued an order approving settlements filed in the 2018 Rate Case and the 2019 Rate Case. Upon issuance of the order and approval of the settlement of the MRT rate cases, the Partnership recognized $17 million of revenues from amounts previously held in reserve related to transportation and storage services performed in 2019. In May 2020, $21 million previously held in reserve was refunded to customers, which is inclusive of interest.

(7) Impairments of Property, Plant and Equipment and Goodwill

Impairment of Property, Plant and Equipment

The Partnership periodically evaluates property, plant and equipment for impairment when events or changes in circumstances indicate that the carrying value of these assets may not be recoverable. The determination of whether an impairment has occurred is based on an estimate of undiscounted cash flows attributable to the assets, as compared to the carrying value of the assets. Due to decreases in natural gas and NGL market prices during 2020 as a result of the ongoing COVID-19 pandemic and the economic effects of the pandemic, together with the dispute over crude oil production levels
18

Table of Contents
between Russia and members of OPEC led by Saudi Arabia, as of March 31, 2020, management reassessed the carrying value of the Atoka assets, in which the Partnership owns a 50% interest in the consolidated joint venture, which is a component of the gathering and processing segment. Based on forecasted future undiscounted cash flows, management determined that the carrying value of the Atoka assets were not fully recoverable. The Partnership utilized the income approach (generally accepted valuation approach) to estimate the fair value of these assets. The primary inputs are forecasted cash flows and the discount rate. The fair value measurement is based on inputs that are not observable in the market and thus represent Level 3 inputs. Applying a discounted cash flow model to the property, plant and equipment, the Partnership recognized a $16 million impairment, which is included in Impairments of property, plant and equipment and goodwill on the Condensed Consolidated Statements of Income during the nine months ended September 30, 2020.

Impairment of Goodwill

In the fourth quarter of 2017, as a result of the acquisition of ETGP, the Partnership recorded $12 million of goodwill associated with the Ark-La-Tex Basin reporting unit, included in the gathering and processing reportable segment.

The Partnership tests its goodwill for impairment annually on October 1st, or more frequently if events or changes in circumstances indicate that the carrying value of goodwill may not be recoverable. Goodwill is assessed for impairment by comparing the fair value of the reporting unit with its book value, including goodwill. During 2020, the commodity price declines due to the existing oversupply of crude oil, NGLs and natural gas were exacerbated by the ongoing COVID-19 pandemic and the economic effects of the pandemic, in addition to the dispute over crude oil production levels between Russia and members of OPEC led by Saudi Arabia in the first quarter. Despite the subsequent agreement in April 2020 by a coalition of nations including Russia and Saudi Arabia to reduce production of crude oil, the price of NGLs and crude oil have remained significantly lower than pre-pandemic levels. Amid such crude oil, NGL and natural gas price declines, producers have been cutting back spending and shifting their focus from emphasizing reserves growth, to increasing net cash flows and reducing outstanding debt, which consequently resulted in a decrease in rig count and in forecasted producer activity in the Ark-La-Tex Basin reporting unit during the first quarter of 2020. At the same time, unit prices and market multiples for midstream companies with gathering and processing operations have dropped to their lowest levels in the last three years. Due to the continuing decrease in forward commodity prices, the reduction in forecasted producer activities, the resulting decrease in our forecasted cash flows and the increase in the weighted average cost of capital, the Partnership determined that the fair value of the goodwill associated with our Ark-La-Tex Basin reporting unit would more likely than not be impaired. As a result, the Partnership performed a quantitative test for our goodwill and determined that the carrying value of the Ark-La-Tex Basin reporting unit exceeded its fair value and that goodwill associated with the Ark-La-Tex Basin was completely impaired in the amount of $12 million. The impairment is included in Impairments of property, plant and equipment and goodwill on the Condensed Consolidated Statements of Income for the nine months ended September 30, 2020.

The following table presents the change in carrying amount of goodwill in each of our reportable segments.

(8) Investment in Equity Method Affiliate
 
The Partnership uses the equity method of accounting for investments in entities in which it has an ownership interest between 20% and 50% and exercises significant influence.
 
SESH is owned 50% by Enbridge, Inc. and 50% by the Partnership. Pursuant to the terms of the SESH LLC Agreement, if, at any time, CenterPoint Energy has a right to receive less than 50% of our distributions through its interest in the Partnership and its economic interest in Enable GP, or does not have the ability to exercise certain control rights, Enbridge, Inc. may, under certain circumstances, have the right to purchase the Partnership’s interest in SESH at fair market value, subject to certain exceptions.

At September 30, 2020, the Partnership estimated the fair value of its investment in SESH was below the carrying value and concluded the decline in value was other than temporary due to the expiration of a transportation contract and the current status of renewal negotiations. As a result, the Partnership recorded a $225 million impairment on its investment in SESH for the three and nine months ended September 30, 2020, which is included in Equity in earnings (losses) of equity method

Table of Contents
affiliate, net in the Partnership’s Condensed Consolidated Statements of Income. The impairment analysis of the Partnership’s investment in SESH compared the estimated fair value of the investment to its carrying value. The fair value of the investment was determined using multiple valuation methodologies under both the market and income approaches. Due to the significant unobservable estimates and assumptions required, the Partnership concluded that the fair value estimate should be classified as a Level 3 measurement within the fair value hierarchy. The basis difference for our investment in SESH has been assigned to its property, plant and equipment and will be amortized over its approximately 50-year remaining useful life. See Note 1 for further information concerning the method used to evaluate and measure the impairment on the Partnership’s investment in SESH.

The Partnership shares operations of SESH with Enbridge, Inc. under service agreements. The Partnership is responsible for the field operations of SESH. SESH reimburses each party for actual costs incurred, which are billed based upon a combination of direct charges and allocations. The Partnership billed SESH $3 million and $2 million during the three months ended September 30, 2020 and 2019, respectively, and $11 million and $12 million during the nine months ended September 30, 2020 and 2019, respectively, associated with these service agreements.

Commercial Paper

The Partnership has a commercial paper program, pursuant to which the Partnership is authorized to issue up to $1.4 billion of commercial paper. The commercial paper program is supported by our Revolving Credit Facility, and outstanding commercial paper effectively reduces our borrowing capacity thereunder. There were $334 million and $155 million outstanding under our commercial paper program at September 30, 2020 and December 31, 2019, respectively. As of September 30, 2020, the weighted average interest rate for the outstanding commercial paper was 0.77%.

Revolving Credit Facility

The Partnership’s Revolving Credit Facility is a $1.75 billion, five-year senior unsecured revolving credit facility, which under certain circumstances may be increased from time to time up to an additional $875 million. The Revolving Credit Facility is scheduled to mature on April 6, 2023, subject to an extension option, which could be exercised two times to extend the term of the Revolving Credit Facility, in each case, for an additional one-year term. As of September 30, 2020, there were zero principal advances, $3 million in letters of credit outstanding and our available borrowing capacity was approximately $775 million under our Revolving Credit Facility.

The Revolving Credit Facility provides that outstanding borrowings bear interest at the LIBOR and/or an alternate base rate, at the Partnership’s election, plus an applicable margin. The applicable margin is based on the Partnership’s designated credit ratings from S&P, Moody’s and Fitch Ratings. As of September 30, 2020, the applicable margin for LIBOR-based borrowings under the Revolving Credit Facility was 1.50% based on the Partnership’s credit ratings. In addition, the Revolving Credit Facility requires the Partnership to pay a fee on unused commitments. The commitment fee is based on the Partnership’s credit ratings. As of September 30, 2020, the commitment fee under the restated Revolving Credit Facility was 0.20% per annum based on the Partnership’s credit ratings. The commitment fee is recorded as interest expense in the Partnership’s Condensed Consolidated Statements of Income.

As of September 30, 2020, the Partnership’s debt included the 2024 Notes, 2027 Notes, 2028 Notes, 2029 Notes and 2044 Notes, which had $8 million of unamortized discount and $20 million of unamortized debt expense at September 30, 2020, resulting in effective interest rates of 4.01%, 4.56%, 5.19%, 4.29% and 4.99%, respectively, during the nine months ended September 30, 2020. In March 2020, the Partnership’s EOIT Senior Notes matured and were paid using proceeds from the Revolving Credit Facility.

During the nine months ended September 30, 2020, the Partnership repurchased $22 million aggregate principal amount of the 2029 Notes and 2044 Notes in open market transactions for approximately $17 million plus accrued interest, which resulted in a $5 million gain on extinguishment of debt. The gain is included in Other, net in the Condensed Consolidated Statements of Income.

As of September 30, 2020, the Partnership was in compliance with all of its debt agreements, including financial covenants.

Credit-Risk Related Contingent Features in Derivative Instruments
 
In the event Moody’s or S&P were to lower the Partnership’s senior unsecured debt rating to a below investment grade rating, the Partnership could be required to provide additional credit assurances to third parties, which could include letters of credit or cash collateral to satisfy its obligation under its financial and physical contracts relating to derivative instruments that are in a net liability position. As of September 30, 2020, under these obligations, the Partnership has posted no cash collateral related to natural gas swaps and swaptions, crude oil swaps and swaptions and NGL swaps and $3 million of additional
25

Table of Contents
collateral would be required to be posted by the Partnership in the event of a credit ratings downgrade to a below investment grade rating. In certain situations where the Partnership’s credit rating is lowered by Moody’s or S&P, the Partnership could be subject to an early termination event related to certain derivative instruments, which could result in a cash settlement of the instruments at market values on the date of such early termination.


(11) Fair Value Measurements
 
Certain assets and liabilities are recorded at fair value in the Condensed Consolidated Balance Sheets and are categorized based upon the level of judgment associated with the inputs used to measure their value. The Partnership determines the appropriate level for each financial asset and liability on a quarterly basis and recognizes transfers between levels at the end of the reporting period. For the three and nine months ended September 30, 2020, there were no transfers between levels. As of September 30, 2020, there were no contracts classified as Level 3.

Estimated Fair Value of Financial Instruments

The fair values of all accounts receivable, notes receivable, accounts payable, commercial paper and other such financial instruments on the Condensed Consolidated Balance Sheets are estimated to be approximately equivalent to their carrying amounts due to their short-term nature and have been excluded from the table below.

The fair value of the Partnership’s Revolving Credit Facility, 2019 Term Loan Agreement, 2024 Notes, 2027 Notes, 2028 Notes, 2029 Notes, 2044 Notes and EOIT Senior Notes is based on quoted market prices and estimates of current rates available for similar issues with similar maturities and is classified as Level 2 in the fair value hierarchy.
 
Non-Financial Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis
 
Certain assets and liabilities are measured at fair value on a nonrecurring basis; that is, the assets and liabilities are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances (e.g., when there is evidence of impairment). As of September 30, 2020, no material fair value adjustments or fair value measurements were required for these non-financial assets or liabilities, other than those discussed in Note 7 and Note 8.

Based upon review of forecast undiscounted cash flows as of September 30, 2020, all of the asset groups were considered recoverable, other than those discussed in Note 7. Based upon review for other than temporary declines in fair value, the investment in equity method affiliate was considered recoverable, other than as discussed in Note 8. Future price declines, throughput declines, contracted capacity declines, cost increases, regulatory or political environment changes and other changes in market conditions, including the oversupply of crude oil, NGLs and natural gas as well as the ongoing COVID-19 pandemic and the economic effects of the pandemic, could reduce forecast undiscounted cash flows for the asset groups and result in other than temporary declines in the fair value of the investment in equity method affiliate.

(14) Commitments and Contingencies
 
The Partnership is routinely involved in legal, environmental, tax and regulatory proceedings before various courts, regulatory commissions and governmental agencies regarding matters arising in the ordinary course of business. Some of these proceedings may from time to time involve substantial amounts. The Partnership regularly analyzes current information and, as necessary, provides accruals for probable liabilities on the eventual disposition of these matters. The Partnership does not currently expect the disposition of these matters to have a material adverse effect on its financial condition, results of operations or cash flows.

On January 1, 2017, the Partnership entered into a 10-year gathering and processing agreement, which became effective on July 1, 2018, with an affiliate of Energy Transfer Partners, LP for deliveries to the Godley Plant in Johnson County, Texas. As of September 30, 2020, the Partnership estimates the remaining associated minimum volume commitment fee to be $175 million. Minimum volume commitment fees are expected to be $3 million for the remainder of 2020, $23 million per year from 2021 through 2027 and $11 million in 2028.

On September 13, 2018, the Partnership executed a precedent agreement for the development of the Gulf Run Pipeline, an interstate natural gas transportation project. On January 30, 2019, a final investment decision was made by Golden Pass LNG, the cornerstone shipper for the liquefied natural gas facility to be served by the Gulf Run Pipeline project. Subject to approval of the project by FERC, the Partnership will be required to construct a large-diameter pipeline from northern Louisiana to Gulf Coast markets. In addition, the Partnership requested approval to transfer existing EGT transportation infrastructure to the Gulf Run Pipeline. The Partnership filed applications with FERC to obtain authorization to construct and operate the pipeline on February 28, 2020. FERC issued the environmental assessment on October 29, 2020. Under the precedent agreement, the Partnership estimates the cost to complete the Gulf Run Pipeline project to fulfill its obligations under the precedent agreement would be as much as $500 million. The project is backed by a 20-year firm transportation service agreement. The Gulf Run Pipeline connects natural gas producing regions in the U.S., including the Haynesville, Marcellus, Utica and Barnett shales and the Mid-Continent region. The project is expected to be placed into service in late 2022.

(16) Reportable Segments

The Partnership’s determination of reportable segments considers the strategic operating units under which it manages sales, allocates resources and assesses performance of various products and services to customers in differing regulatory environments. The accounting policies of the reportable segments are the same as those described in the summary of significant accounting policies excerpt in the Partnership’s audited 2019 Consolidated Financial Statements included in the Annual Report. The Partnership uses operating income as the measure of profit or loss for its reportable segments.

The Partnership’s assets and operations are organized into two reportable segments: (i) gathering and processing, which primarily provides natural gas and crude oil gathering and natural gas processing services to our producer customers, and (ii) transportation and storage, which provides interstate and intrastate natural gas pipeline transportation and storage service primarily to our producer, power plant, LDC and industrial end-user customers.

Overview

Enable Midstream Partners, LP is a Delaware limited partnership formed in May 2013 to own, operate and develop midstream energy infrastructure assets strategically located to serve our customers. We completed our initial public offering in April 2014, and we are traded on the New York Stock Exchange under the symbol “ENBL.” Our general partner is owned by CenterPoint Energy and OGE Energy. In this report, the terms “Partnership” and “Registrant” as well as the terms “our,” “we,” “us” and “its,” are sometimes used as abbreviated references to Enable Midstream Partners, LP together with its consolidated subsidiaries.

Our assets and operations are organized into two reportable segments: (i) gathering and processing and (ii) transportation and storage. Our gathering and processing segment primarily provides natural gas and crude oil gathering and natural gas processing services to our producer customers and crude oil, condensate and produced water gathering services to our producer and refiner customers. Our transportation and storage segment provides interstate and intrastate natural gas pipeline transportation and storage services primarily to our producer, power plant, LDC and industrial end-user customers.

Our natural gas gathering and processing assets are primarily located in Oklahoma, Texas, Arkansas and Louisiana and serve natural gas production in the Anadarko, Arkoma and Ark-La-Tex Basins. Our crude oil gathering assets are located in Oklahoma and North Dakota and serve crude oil production in the Anadarko and Williston Basins. Our natural gas transportation and storage assets consist primarily of an interstate pipeline system extending from western Oklahoma and the Texas Panhandle to Louisiana, an interstate pipeline system extending from Louisiana to Illinois, an intrastate pipeline system in Oklahoma and our investment in SESH, an interstate pipeline extending from Louisiana to Alabama.

We expect our business to continue to be affected by the key trends included in our Annual Report, as well as the recent developments discussed herein, including the impacts of the COVID-19 pandemic. Our expectations are based on assumptions made by us and information currently available to us. To the extent our underlying assumptions about, or interpretations of, available information prove to be incorrect, our actual results may vary materially from our expected results.

Our primary business objective is to increase the cash available for distribution to our unitholders over time while maintaining our financial flexibility. Our business strategies for achieving this objective include capitalizing on organic growth opportunities associated with our strategically located assets, growing through accretive acquisitions, maintaining strong customer relationships to attract new volumes and expand beyond our existing asset footprint and business lines, and continuing to minimize direct commodity price exposure through fee-based contracts. As part of these efforts, we continuously engage in discussions with new and existing customers regarding potential projects to develop new midstream assets to support their needs as well as discussions with potential counterparties regarding opportunities to purchase or invest in complementary assets in new operating areas or midstream business lines. These growth, acquisition and development efforts often involve assets which, if acquired or constructed, could have a material effect on our financial condition and results of operations.


Recent Developments

COVID-19 Pandemic

In March 2020, the World Health Organization categorized the recent outbreak of COVID-19 as a pandemic. The COVID-19 pandemic has led to significant economic disruption globally, including in the areas of the United States in which we operate. Governmental authorities took actions to limit the spread of COVID-19 through travel restrictions and stay-at-home orders, which caused many businesses to adjust, reduce or suspend activities. Concerns about global economic growth, as well as uncertainty regarding the timing, pace and extent of an economic recovery in the United States and abroad, have had a significant adverse impact on commodity prices and financial markets. Following the lifting of travel restrictions and stay-at-home orders, COVID-19 cases in the United States have increased, creating additional uncertainty regarding the timing, pace and extent of an economic recovery in the United States.

Our gathering and processing and our transportation and storage assets have continued to operate as critical infrastructure necessary to support the supply of natural gas, NGLs and crude oil. Beginning in March 2020, we took action to protect the health and safety of our workers, while continuing to operate, and to maintain the safety and integrity of, our assets. Where possible, our employees have worked remotely to support our business. Where continuous remote work was not possible, we implemented strategies to reduce the likelihood of spreading the disease. In compliance with Center for Disease Control guidance, these strategies include requiring sick employees to stay home, conducting daily virtual health checks, implementing policies and practices for social distancing and wearing cloth face coverings, educating employees about steps they can take to protect themselves at work and at home, performing enhanced cleaning and disinfecting, limiting non-essential travel, and
34

Table of Contents
minimizing meetings and gatherings. For contractors, vendors, and suppliers who are necessary to support our operations on-site, we have required them to implement similar policies and practices.

In June 2020, we began to return those employees to the workplace that have beem working remotely. As part of our return to work protocols, we implemented the same strategies described above to reduce the likelihood of spreading the disease. In addition, we have limited the number of employees in the workplace in order to maintain strict social distancing practices and made accommodations for employees at higher risk of severe illness. As infection and hospitalization rates have increased in areas where we operate, we have temporarily halted returning additional employees to the office. We intend to increase the number of employees in the workplace as conditions warrant, and we will continue to monitor for the emergence or resurgence of COVID-19 in our workplaces and in the communities where our employees are located.

Market Dynamics

Prior to the COVID-19 pandemic, the price of natural gas, NGLs and crude oil had begun to decline due to oversupply. The price of, and global demand for, these commodities have continued to decline significantly as a result of the ongoing economic effects of the COVID-19 pandemic and the significant governmental measures being implemented to control the spread of the virus. In addition, the dispute in the first quarter of 2020 over crude oil production levels between Russia and members of OPEC led by Saudi Arabia exacerbated the decline in the prices of NGLs and crude oil. Despite the subsequent agreement in April 2020 by a coalition of nations, including Russia and Saudi Arabia, to reduce production of crude oil, the prices of NGLs and crude oil have remained depressed relative to pre-pandemic levels.

Financial markets have recently experienced extreme volatility as a result of the economic uncertainty arising out of the COVID-19 pandemic. Market volatility, together with deteriorating credit, liquidity concerns, decreasing production, and increasing inventories, are conditions that are associated with a general economic downturn. Producers have announced and implemented plans to reduce production and decrease the drilling and completion of wells in response to these conditions. These plans include reductions in the exploration, development and production activity across our areas of operation. As a result, the effects of the COVID-19 pandemic have and may continue to negatively impact the demand for midstream services.

The effects of the COVID-19 pandemic, which have exacerbated commodity price declines resulting from oversupply by decreasing demand, may also increase counterparty credit risk. Some customers may encounter severe financial problems that could limit our ability to collect amounts owed to us or to enforce performance of other obligations under contractual arrangements. During the nine months ended September 30, 2020, five of our producer customers filed for reorganization under Chapter 11 of the Bankruptcy Code. We do not anticipate that these bankruptcies will result in a significant impact on our results of operations.

During the three and nine months ended September 30, 2020 as compared to the three and nine months ended September 30, 2019, our natural gas gathered volumes, processed volumes, transported volumes, revenues and gross margin decreased. These decreases resulted primarily from reductions in the production of natural gas combined with reductions in the demand for natural gas, NGLs and crude oil. The reductions in supply and demand for these commodities, and the resulting decrease in demand for midstream services, were caused by the effects of preexisting oversupply conditions and exacerbated by the decrease in economic activity due to the COVID-19 pandemic. While we believe that the demand for midstream services will remain below 2019 levels for as long as these conditions persist, the results for our most recent period may not be indicative of our future results because of the continuing uncertainty surrounding future levels of production of natural gas, NGLs and crude oil and the demand for midstream services to move that production to markets, as well as uncertainty regarding the creditworthiness of our customers. For more information on our results, see “Results of Operations” below.

We continue to actively respond to the impacts of these developments on our business. On April 1, 2020, we announced distribution, capital and cost reductions intended to fortify our financial position, protect our balance sheet and ensure our liquidity. These measures include:
A 50% reduction in our quarterly distribution per common unit from $0.3305 to $0.16525 to retain cash in order to provide funding for our capital investment program;
A $115 million reduction from the high end of the range of our previously forecast expansion capital expenditures for 2020, which limits our forecast expansion capital expenditures primarily to projects that serve incremental firm transportation commitments and support expected levels of contracted producer activity;
A $35 million decrease in forecast operations and maintenance and general and administrative expenses for 2020, that we anticipate will grow to a $70 million run-rate savings in 2021; and
A reduction in maintenance capital of $20 million, or 17%, from the midpoint of our previously provided outlook for 2020, that we anticipate continuing in 2021.

35

Table of Contents
We continue to believe that these measures will allow us to fully fund our business and reduce our total debt in 2020.

As part of the reduction in our operations and maintenance and general and administrative expenses, in the fourth quarter of 2019, we began a review of our organizational structure and staffing levels to maximize efficiency and flexibility. As a result of this review, we have reduced our positions by 165 through July 31, 2020. Of these 165 reductions, 134 were made between May 1, 2020 through July 31, 2020. We believe that these reductions will improve our long-term cost structure.

Our Revolving Credit Facility and our 2019 Term Loan Agreement each contain a financial covenant limiting our ratio of consolidated funded indebtedness to consolidated earnings before interest, taxes, depreciation and amortization as of the last day of each fiscal quarter of less than or equal to 5.00 to 1.00. Our financial results, which have been impacted by the effects of preexisting oversupply conditions and exacerbated by the decrease in economic activity due to the COVID-19 pandemic, have lowered our aggregate borrowing capacity under our Revolving Credit Facility. As of September 30, 2020, our available borrowing capacity under our Revolving Credit Facility was approximately $775 million. Considering these financial covenants, we believe that we will have sufficient cash flow and borrowing capacity to fully fund our business and expect to continue to proactively take steps to maintain sufficient liquidity and capital resources for our business.

We were not eligible and did not receive any assistance under the Paycheck Protection Program. Under the CARES Act, we elected to defer employer payroll taxes incurred in 2020, into 2021 and 2022. Additionally, we elected to apply the net operating loss carryback provisions of the CARES Act to Enable Midstream Services, LLC. Applying these provisions will not significantly impact our short-term or long-term liquidity needs.

We cannot currently predict the duration and extent of the impact of the COVID-19 pandemic on the financial and commodity markets, or the duration and extent of the impact global oversupply on the production of natural gas, NGLs and crude oil or the demand for midstream services. Depending upon the duration and extent of reduced economic activity from the COVID-19 pandemic and attendant reduction in demand for hydrocarbons, as well as the global oversupply of natural gas, NGLs and crude oil and the attendant reduction in producer activities and energy commodity prices, we may experience asset impairments in future reporting periods.

Commercial Update

Sale of Interest in Bistineau Storage Facility

On April 1, 2020, the Partnership closed on the sale of its undivided 1/12th interest in the Bistineau Storage Facility in Louisiana for approximately $19 million. We did not recognize a gain or loss on this transaction.

Loss on Retirement of Ark-La-Tex Gathering System

In April 2020, the Partnership sustained damage to an approximately 100-mile gas gathering system in the Ark-La-Tex Basin of our gathering and processing segment. We have ceased operation of this system and are in process of retiring it. We recognized a loss on retirement of approximately $20 million during the second quarter of 2020.

Dakota Access Pipeline

On July 6, 2020, the federal district court for the District of Columbia issued an order requiring Dakota Access Pipeline to be shut down and emptied of oil by August 5, 2020, pending the completion of an environmental impact analysis for the pipeline. The U.S. Court of Appeals for the District of Columbia Circuit stayed the order requiring the shut down in order to consider the pipeline’s emergency motion for stay. Substantially all of the crude oil gathered by our Williston Basin crude oil systems is delivered indirectly for transport to Dakota Access Pipeline. Although the crude oil gathered by our Williston Basin crude oil systems may also be delivered for transport to other pipelines, such as BakkenLink Pipeline and Bridger Pipeline, a shutdown of the Dakota Access Pipeline, or any other significant pipeline providing transportation services from the Williston Basin, would likely result in the shut in of wells connected to our Williston Basin crude oil systems if our customer is unable to obtain sufficient capacity on those pipelines at an effective cost. On August 5, 2020, the DC Circuit: (1) stayed the injunction issued by the district court, finding that the district court failed to make the findings necessary for injunctive relief, but (2) denied the motion to stay the district court’s order vacating the easement authorizing Dakota Access Pipeline to cross the Missouri River at Lake Oahe. Oral argument has been set for November 4, 2020 in Dakota Access Pipeline’s appeal of the district court’s order requiring the U.S. Army Corps of Engineers to conduct an environmental impact statement prior to granting an easement authorizing Dakota Access Pipeline to cross the Missouri River at Lake Oahe. Under the briefing schedule approved by the DC Circuit, the earliest a ruling could be expected is late December 2020. Although the threatened shutdown of Dakota Access Pipeline is no longer imminent, a shutdown could occur if Dakota Access Pipeline loses its appeal and the U.S. Army Corps of Engineers either does not grant Dakota Access Pipeline an easement following the completion of the
36

Table of Contents
environmental impact statement or determines that, under the U.S. Army Corps of Engineers regulations, Dakota Access Pipeline must be shut down while the environmental impact statement is prepared. We are unable to predict whether any such pipeline will be shutdown, the duration of any such shutdown, or the extent of the resulting impact on the operations of our Williston Basin crude oil and produced water gathering systems.

Impairment of equity method affiliate investment

As of September 30, 2020, the Partnership estimated the fair value of its equity method affiliate investment was below the carrying value and concluded the decline in value was other than temporary due to the expiration of a transportation contract and the current status of renewal negotiations. As a result, the Partnership recorded a $225 million impairment on its equity method affiliate investment for the three and nine months ended September 30, 2020, which is included in Equity in earnings (losses) of equity method affiliate, net in the Partnership’s Condensed Consolidated Statements of Income.

Regulatory Update

MRT Rate Case

On March 26, 2020, FERC issued an order approving settlements filed in the MRT rate cases filed in June 2018 and October 2019. The settlements include contract extensions for most firm transportation and storage customers through July 31, 2024. Upon issuance of the order and approval of the settlements of the MRT rate cases, the Partnership recognized $17 million of revenues from amounts previously held in reserve related to transportation and storage services performed in 2019. In May 2020, $21 million previously held in reserve was refunded to customers, which was inclusive of interest.

PHMSA Update

On July 1, 2020, the Safety of Hazardous Liquid Pipelines rule and the Safety of Gas Transmission Pipelines rule became effective. We do not anticipate that we will incur material compliance costs in connection with these rules in 2020, and we estimate that we will incur an average of $10 million per year in additional costs to comply with these rules beginning in 2022.

The Pipeline Safety: Safety of Gas Transmission Pipelines, Repair Criteria, Integrity Management Improvements, Cathodic Protection, Management of Change, and Other Related Amendments Rule and the Safety of Gas Gathering Pipelines rule, are expected to be published and effective in 2021. While we cannot predict the outcome of pending or future legislative or regulatory initiatives, we anticipate that pipeline safety requirements will continue to become more stringent over time. As a result, we may incur significant additional costs to comply with the pending pipeline safety regulations, and any other future pipeline safety laws and regulations, which could have a material impact on our costs of and revenues from operations.

Five Nations Reservations

On July 9, 2020, the U.S. Supreme Court ruled that the Muscogee (Creek) Nation reservation in Eastern Oklahoma has not been disestablished. Prior to the court’s ruling, the prevailing view was that the Muscogee (Creek) Nation, Chickasaw Nation, Cherokee Nation, Choctaw Nation and Seminole Nation reservations within Oklahoma had been disestablished prior to statehood in 1907. Although the court’s ruling indicates that it is limited to criminal law as applied within the Muscogee (Creek) Nation reservation, the ruling has significant potential implications for civil law within the Muscogee (Creek) Nation reservation, as well as other reservations in Oklahoma that may similarly be found to not have been disestablished. A significant amount of our gathering and processing and transportation and storage assets are located in Oklahoma on the Muscogee (Creek) Nation reservation and other reservations that may similarly be found to not have been disestablished. While we cannot predict which other reservations may similarly be found not to have been disestablished or the full extent to which civil jurisdiction may be affected, the ruling could significantly impact laws and regulations to which we are subject in Oklahoma, such as taxation and the permitting and siting of energy assets.

State district courts in Oklahoma, applying the analysis in U.S. Supreme Court’s ruling regarding the Muscogee (Creek) Nation, ruled on September 30, 2020 that the Cherokee Nation reservation has not been disestablished and on October 13, 2020 that the Chickasaw Nation reservation has not been disestablished. We anticipate that similar rulings will be made regarding the Choctaw Nation and Seminole Nation reservations in the near future because the reservations of all five nations share a similar history. On October 1, 2020, the EPA granted approval to the State of Oklahoma under Section 10211(a) of the Safe, Accountable, Flexible, Efficient Transportation Equity Act of 2005 (the “SAFETE Act”) to administer all of the State’s existing EPA-approved regulatory programs to Indian Country within the State except: Indian allotments to which Indian titles have not been extinguished; lands that are held in trust by the United States on behalf of any Indian or Tribe; lands that are owned in fee by any Tribe where title was acquired through a treaty with the United States to which such Tribe is a party and that have never been allotted to any citizen or member of such Tribe. The approval extends the State’s authority for existing EPA-approved regulatory programs to all lands within the State to which the State applied such programs prior to the U.S. Supreme Court’s
37

Table of Contents
ruling regarding the Muscogee (Creek) Nation reservation. However, several Tribes have expressed dissatisfaction with the consultation process performed in relation to this approval and it is possible that the EPA’s approval under the SAFETE Act could be challenged. Additionally, the SAFETE Act provides that any Tribe in Oklahoma may seek “Treatment as a State” by the EPA, and it is possible that one or more of the Tribes in Oklahoma may seek such an approval from the EPA. At this time, we cannot predict how these jurisdictional issues may ultimately be resolved.

Environmental Update

In April 2020, the federal district court for the district of Montana issued an order vacating the U.S. Army Corps of Engineers Clean Water Act Section 404 Nationwide Permit 12 (NWP 12) for alleged failure to comply with consultation requirements under the federal Endangered Species Act. Pipeline companies and other developers of underground infrastructure frequently rely upon NWP 12 and other general permits for construction and maintenance projects in jurisdictional wetland areas. The federal district court subsequently limited the order to vacate NWP 12 only with respect to pipeline construction. In May 2020, the U.S. Army Corps of Engineers appealed the federal district court’s order to the U.S. Court of Appeals for the Ninth Circuit. In July 2020, the U.S. Supreme Court granted a stay of the district court’s order vacating NWP 12, pending the disposition of the appeal in the Ninth Circuit and any subsequent appeal to the Supreme Court. Additionally, on September 15, 2020, the U.S. Army Corps of Engineers published a proposal to reissue its existing Nationwide Permits and associated general conditions and definitions, with some modifications, including proposed modifications to NWP 12. That proposal is subject to a 60-day public comment period. While the full extent and impact of the court’s action, as well as the proposed NWP 12 re-issuance, is unclear at this time, a disruption in our ability to obtain coverage under NWP 12 or other general permits may result in increased costs and project delays if we are required to seek individual permits from the U.S. Army Corps of Engineers.

Liquidity Update

EOIT Senior Notes

On March 16, 2020, the Partnership’s EOIT Senior Notes matured and were paid using proceeds from the Revolving Credit Facility. For more information, please see Note 9 of the Notes to Condensed Consolidated Financial Statements.

Repurchase of Senior Notes

During the nine months ended September 30, 2020, the Partnership repurchased $22 million aggregate principal amount of the 2029 Notes and 2044 Notes in open market transactions for approximately $17 million plus accrued interest, which resulted in a $5 million gain on extinguishment of debt.

Gathering and Processing

Three months ended September 30, 2020 compared to three months ended September 30, 2019. Our gathering and processing segment reported operating income of $57 million for the three months ended September 30, 2020 compared to operating income of $138 million for the three months ended September 30, 2019. The difference of $81 million in operating income between periods was primarily due to an $85 million decrease in gross margin, partially offset by a $2 million decrease in operation and maintenance and general and administrative expenses and a $2 million decrease in depreciation and amortization expense during the three months ended September 30, 2020.

Our gathering and processing segment revenues decreased $79 million. The decrease was primarily due to the following:
    Product Sales:
changes in the fair value of natural gas, condensate and NGL derivatives decreased $12 million,
revenues from natural gas sales decreased $11 million due to lower sales volumes, partially offset by higher average sales prices, and
realized gains on natural gas, condensate and NGL derivatives decreased $6 million.
These decreases were partially offset by revenues from NGL sales which increased $6 million primarily due to an increase in the average realized sales price from higher average market prices for all NGL products other than natural gasoline and higher recoveries of ethane in the Anadarko Basin, partially offset by lower sales in the Arkoma and Ark-La-Tex Basin primarily due to lower processed volumes.
    Service Revenues:
natural gas gathering revenues decreased $51 million due to lower gathered volumes, inclusive of continued producer shut-ins in the Anadarko Basin that ended during the third quarter, lower shortfall fees associated with the expiration of certain minimum volume commitment contracts in the Ark-La-Tex Basin and lower revenue associated with the third quarter 2019 amendment of certain minimum volume commitment contracts in the Arkoma Basin and
processing service revenues decreased $6 million due to lower processed volumes under fee-based arrangements, partially offset by higher consideration received from percent-of-proceeds, percent-of-liquids and keep-whole processing arrangements due to an increase in retained volumes at higher average market prices as well as an increase in the recognition of certain annual minimum processing fees.

These decreases were partially offset by crude oil, condensate and produced water gathering revenues which increased by $1 million primarily due to an increase in gathered crude oil volumes in the Anadarko Basin, partially offset by a decrease in gathered crude oil volumes in the Williston Basin.

Our gathering and processing segment gross margin decreased $85 million. The decrease was primarily due to the following:
natural gas gathering fees decreased $51 million due to lower gathered volumes, inclusive of continued producer shut-ins in the Anadarko Basin that ended during the third quarter, lower shortfall fees associated with the expiration of certain minimum volume commitment contracts in the Ark-La-Tex Basin and lower revenue associated with the third quarter 2019 amendment of certain minimum volume commitment contracts in the Arkoma Basin,
revenues from natural gas sales less the cost of natural gas decreased approximately $15 million due to lower sales volumes, partially offset by higher average sales prices,
changes in the fair value of natural gas, condensate and NGL derivatives decreased $12 million,
realized gains on natural gas, condensate and NGL derivatives decreased $6 million, and
processing service revenues decreased $6 million due to lower processed volumes under fee-based arrangements, partially offset by higher consideration received from percent-of-proceeds, percent-of-liquids and keep-whole processing arrangements due to an increase in retained volumes at higher average market prices as well as an increase in the recognition of certain annual minimum processing fees.
These decreases were partially offset by:
revenues from NGL sales less the cost of NGLs increased $4 million due to higher average sales prices for all NGL products other than natural gasoline and
crude oil, condensate and produced water gathering revenues increased $1 million primarily due to an increase in gathered crude oil volumes in the Anadarko Basin, partially offset by a decrease in gathered crude oil volumes in the Williston Basin.

Our gathering and processing segment operation and maintenance and general and administrative expenses decreased $2 million. The decrease was primarily due to a $4 million decrease in compressor rentals and a $1 million decrease in payroll-related costs. These decreases were partially offset by a $2 million increase in materials and supplies due to the timing of operation and maintenance activities, a $1 million gain on retirement of assets in the prior year with no comparable item in the current year, and a $1 million increase due to lower capitalized overhead costs.

Our gathering and processing segment depreciation and amortization decreased $2 million. The decrease was primarily related to new depreciation rates implemented in the prior year which resulted in higher depreciation expense in 2019 for certain assets with shorter remaining useful lives, as compared to 2020, partially offset by additional assets placed in service.

Nine months ended September 30, 2020 compared to nine months ended September 30, 2019. Our gathering and processing segment reported operating income of $167 million for the nine months ended September 30, 2020 compared to operating income of $366 million for the nine months ended September 30, 2019. The difference of $199 million in operating income between periods was primarily due to a $164 million decrease in gross margin, $28 million of property, plant and equipment and goodwill impairments recognized in 2020, a $12 million increase in operation and maintenance and general and administrative expenses and a $1 million increase in taxes other than income tax, partially offset by a $6 million decrease in depreciation and amortization during the nine months ended September 30, 2020.

Our gathering and processing segment revenues decreased $428 million. The decrease was primarily due to the following:
    Product Sales:
revenues from NGL sales decreased $219 million primarily due to a decrease in the average realized sales price from lower average market prices for NGL products and lower processed volumes,
revenues from natural gas sales decreased $130 million due to lower average sales prices and lower sales volumes, and
changes in the fair value of natural gas, condensate and NGL derivatives decreased $13 million.
These decreases were partially offset by realized gains on natural gas, condensate and NGL derivatives, which increased $5 million.
    Service Revenues:

Table of Contents
natural gas gathering revenues decreased $57 million due to lower gathered volumes in the Anadarko and Arkoma Basins, inclusive of continued producer shut-ins in the Anadarko Basin that ended during the third quarter, lower shortfall fees associated with the expiration of certain minimum volume commitment contracts in the Ark-La-Tex and Arkoma Basins and lower revenue associated with the third quarter 2019 amendment of certain minimum volume commitment contracts in the Arkoma Basin,
processing service revenues decreased $14 million due to lower processed volumes under fee-based arrangements, partially offset by higher consideration received from percent-of-proceeds, percent-of-liquids and keep-whole processing arrangements due to an increase in retained volumes at lower average market prices as well as an increase in the recognition of certain annual minimum processing fees, and
a $1 million decrease in intercompany management fees.
These decreases were partially offset by crude oil, condensate and produced water gathering revenue, which increased $1 million primarily due to an increase in gathered crude oil volumes in the Anadarko Basin, partially offset by a decrease in gathered crude oil volumes in the Williston Basin.

Our gathering and processing segment gross margin decreased $164 million. The decrease was primarily due to the following:
natural gas gathering fees decreased $57 million due to lower gathered volumes in the Anadarko and Arkoma Basins, inclusive of continued producer shut-ins in the Anadarko Basin that ended during the third quarter, lower shortfall fees associated with the expiration of certain minimum volume commitment contracts in the Ark-La-Tex and Arkoma Basins and lower revenue associated with the third quarter 2019 amendment of certain minimum volume commitment contracts in the Arkoma Basin,
revenues from natural gas sales less the cost of natural gas decreased approximately $53 million due to lower average sales prices and lower sales volumes,
revenues from NGL sales less the cost of NGLs decreased $32 million due to lower volumes and lower average market prices for NGL products,
processing service fees decreased $14 million due to lower processed volumes under fee-based arrangements, partially offset by higher consideration received from percent-of-proceeds, percent-of-liquids and keep-whole processing arrangements due to an increase in retained volumes at lower average market prices as well as an increase in the recognition of certain annual minimum processing fees,
changes in the fair value of natural gas, condensate and NGL derivatives decreased $13 million, and
a $1 million decrease in intercompany management fees.
These decreases were partially offset by:
realized gains on natural gas, condensate and NGL derivatives, which increased $5 million and
crude oil, condensate and produced water gathering revenues increased $1 million primarily due to an increase in gathered crude oil volumes in the Anadarko Basin, partially offset by a decrease in gathered crude oil volumes in the Williston Basin.

Our gathering and processing segment operation and maintenance and general and administrative expenses increased $12 million. The increase was primarily due to a $19 million increase in loss on retirement of assets driven by a $20 million loss on retirement of an Ark-La-Tex gathering system in 2020 as compared to $1 million in losses on retirement in the prior year, a $4 million increase due to lower capitalized overhead costs, and a $1 million increase in payroll-related costs. These increases were partially offset by an $8 million decrease in compressor rentals, a $2 million decrease in materials and supplies due to the timing of operation and maintenance activities and a $1 million decrease in office and travel expenses due to travel restrictions and employees working remotely.

During the nine months ended September 30, 2020, our gathering and processing segment recognized impairments of property, plant and equipment and goodwill of $28 million. Due to decreases of crude oil and natural gas prices during 2020, management reassessed the carrying value of the Partnership's investment in the Atoka assets, a component of the gathering and processing segment. Based on forecast future undiscounted cash flows, the Partnership determined that the carrying value of the Atoka assets was not fully recoverable and recognized $16 million of impairment expense. Due to the continuing decreases in forward commodity prices, the reduction in forecast producer activities, the resulting decrease in our forecast cash flows and the increase in the weighted average cost of capital, the Partnership determined that the fair value of the goodwill associated with our Ark-La-Tex Basin reporting unit was completely impaired and recognized $12 million of impairment expense.

Our gathering and processing segment depreciation and amortization decreased $6 million. The decrease was primarily related to new depreciation rates implemented in the prior year which resulted in higher depreciation expense in 2019 for certain assets with shorter remaining useful lives, as compared to 2020, partially offset by additional assets placed in service.

Our gathering and processing segment taxes other than income tax increased $1 million related to higher accrued ad valorem taxes due to additional assets placed in service.

Transportation and Storage

Three months ended September 30, 2020 compared to three months ended September 30, 2019. Our transportation and storage segment reported operating income of $43 million for the three months ended September 30, 2020 compared to operating income of $37 million for the three months ended September 30, 2019. The difference of $6 million in operating income between periods was primarily due to a $10 million decrease in operation and maintenance and general and administrative expenses and a $1 million decrease in depreciation and amortization, partially offset by a $5 million decrease in gross margin.

Our transportation and storage segment revenues decreased $29 million. The decrease was primarily due to the following:
    Product Sales:
revenues from natural gas sales decreased $18 million primarily due to lower sales volumes, partially offset by higher average sales prices,
revenues from NGL sales decreased $3 million due to lower average sales prices and lower volumes, and
changes in the fair value of natural gas derivatives decreased $1 million.
These decreases were partially offset by realized gains on natural gas derivatives, which increased $1 million.
    Service Revenues:
volume-dependent transportation and storage revenues decreased $5 million due to lower off-system intrastate transportation rates and lower transported volumes due to decreased production activity in the Anadarko Basin and
firm transportation and storage services decreased $3 million due to lower interstate contracted capacity, partially offset by higher recognized rates subsequent to the settlement of the MRT rate case.

Our transportation and storage segment gross margin decreased $5 million. The decrease was primarily due to the following:
volume-dependent transportation and storage revenues decreased $5 million due to lower off-system intrastate transportation rates and lower transported volumes due to decreased production activity in the Anadarko Basin,
firm transportation and storage services decreased $3 million due to lower interstate contracted capacity, partially offset by higher recognized rates subsequent to the settlement of the MRT rate case,
a $2 million decrease due to incremental lower of cost or net realizable value adjustments related to natural gas storage inventories, and
changes in the fair value of natural gas derivatives decreased $1 million.
These decreases were partially offset by:
system management activities increased $5 million and
realized gains on natural gas derivatives, which increased $1 million.

Our transportation and storage segment operation and maintenance and general and administrative expenses decreased $10 million. The decrease was primarily driven by a $5 million decrease related to claims settlement costs in the prior year with no comparable activity in the current year, a $4 million reduction in the estimated retirement loss previously recognized in 2019 related to a physical property loss, a $2 million decrease in professional services due to higher rate case costs in the prior year, $1 million decrease in office and travel expenses due to the impact of travel restrictions and employees working remotely and a $1 million decrease in payroll-related costs. These decreases were partially offset by a $4 million increase in materials and supplies and outside services due to pipeline safety and storage integrity work under our pipeline safety program and to comply with certain PHMSA regulations.

Our transportation and storage segment depreciation and amortization decreased $1 million primarily due to retirements of general plant assets.

Our transportation and storage segment reported operating income of $159 million for the nine months ended September 30, 2020 compared to operating income of $141 million for the nine months ended September 30, 2019. The difference of $18 million in operating income between periods was primarily due to a $15 million decrease in operation and maintenance and general and administrative expenses, a $3 million decrease in depreciation and amortization, and a $1 million decrease in taxes other than income tax, partially offset a $1 million decrease in gross margin.

Our transportation and storage segment revenues decreased $180 million. The decrease was primarily due to the following:
    Product Sales:
revenues from natural gas sales decreased $158 million primarily due to lower sales volumes and lower average sales prices,
revenues from NGL sales decreased $9 million due to lower average sales prices and lower volumes, and
changes in the fair value of natural gas derivatives decreased $1 million.
    Service Revenues:
volume-dependent transportation and storage revenues decreased $10 million due to lower off-system intrastate transportation rates and lower transported volumes due to decreased production activity in the Anadarko Basin, partially offset by the recognition of $1 million of revenue upon the settlement of the MRT rate case and
firm transportation and storage services decreased $2 million due to lower interstate contracted capacity and lower rates on certain contracts for intrastate service with power generators, partially offset by an increase in recognized rates and the recognition of $16 million of previously reserved revenue upon the settlement of the MRT rate case.

Our transportation and storage segment gross margin decreased $1 million. The decrease was primarily due to the following:
volume-dependent transportation and storage revenues decreased $10 million due to lower off-system intrastate transportation rates and lower transported volumes due to decreased production activity in the Anadarko Basin, partially offset by the recognition of $1 million of revenue upon the settlement of the MRT rate case,
a $3 million decrease due to incremental lower of cost or net realizable value adjustments related to natural gas storage inventories,

Three Months Ended September 30, 2020 compared to Three Months Ended September 30, 2019

Net Income (Loss) Attributable to Limited Partners. We reported net loss attributable to limited partners of $164 million in the three months ended September 30, 2020 compared to net income attributable to limited partners of $132 million in the three months ended September 30, 2019. The decrease in net income attributable to limited partners of $296 million was primarily attributable to a decrease in equity in earnings (losses) of equity method affiliate, net of $227 million and a decrease in operating income of $75 million, partially offset by a decrease in interest expense of $5 million and an increase in other, net of $1 million in the three months ended September 30, 2020.

Equity in Earnings (Losses) of Equity Method Affiliate, net. Equity in earnings (losses) of equity method affiliate, net decreased $227 million primarily due to a $225 million impairment of the Partnership’s equity method affiliate investment in the third quarter of 2020.

Interest Expense. Interest expense decreased $5 million primarily due to lower interest rates on the Partnership’s short-term borrowings.

Nine Months Ended September 30, 2020 compared to Nine Months Ended September 30, 2019

Net Income (Loss) Attributable to Limited Partners. We reported net loss attributable to limited partners of $8 million in the nine months ended September 30, 2020 compared to net income attributable to limited partners of $378 million in the nine months ended September 30, 2019. The decrease in net income attributable to limited partners of $386 million was primarily attributable to a decrease in equity in earnings (losses) of equity method affiliate, net of $223 million, a decrease in operating income of $181 million, and an income tax benefit of $1 million in the prior year with no tax effect in the current year, partially offset by a decrease in interest expense of $6 million, an increase in other, net of $5 million and an $8 million change in net income (loss) attributable to noncontrolling interest in the nine months ended September 30, 2020.

Equity in Earnings (Losses) of Equity Method Affiliate, net. Equity in earnings (losses) of equity method affiliate, net decreased $223 million primarily due to a $225 million impairment of the Partnership’s equity method affiliate investment in the third quarter of 2020.

Interest Expense. Interest expense decreased $6 million primarily due to lower interest rates on the Partnership’s short-term borrowings.

Table of Contents
Other, net. Other, net increased $5 million primarily due to a gain on extinguishment of debt.

Net Income (Loss) Attributable to Noncontrolling Interest. Net income (loss) attributable to noncontrolling interest changed $8 million primarily due to an impairment in 2020 in the Partnership’s Atoka assets of which the Partnership owns a 50% interest in the consolidated joint venture.


Reconciliations of Non-GAAP Financial Measures

The Partnership has included the non-GAAP financial measures Gross margin, Adjusted EBITDA, Adjusted interest expense, DCF and Distribution coverage ratio in this report based on information in its Condensed Consolidated Financial Statements. Gross margin, Adjusted EBITDA, Adjusted interest expense, DCF and Distribution coverage ratio are part of the performance measures that we use to manage the Partnership.

Provided below are reconciliations of Gross margin to total revenues, Adjusted EBITDA and DCF to net income attributable to limited partners, and Adjusted EBITDA to net cash provided by operating activities and Adjusted interest expense to interest expense, the most directly comparable GAAP financial measures, on a historical basis, as applicable, for each of the periods indicated. Gross margin, Adjusted EBITDA, Adjusted interest expense, DCF and Distribution coverage ratio should not be considered as alternatives to net income, operating income, total revenues, cash flow from operating activities or any other measure of financial performance or liquidity presented in accordance with GAAP. These non-GAAP financial measures have important limitations as analytical tools because they exclude some but not all items that affect the most directly comparable GAAP measures. Additionally, because Gross margin, Adjusted EBITDA, Adjusted interest expense, DCF and Distribution coverage ratio may be defined differently by other companies in the Partnership’s industry, these measures may not be comparable to similarly titled measures of other companies, thereby diminishing their utility.

Liquidity and Capital Resources

The Partnership’s principal liquidity requirements are to finance its operations, fund capital expenditures and acquisitions, make cash distributions and satisfy any indebtedness obligations. Additionally, we may from time to time seek to retire or purchase our outstanding debt through cash purchases, in open market purchases, privately negotiated transactions, tender offers or otherwise. Such repurchases, if any, will depend on prevailing market conditions, our liquidity requirements, contractual restrictions and other factors. We expect that our liquidity and capital resource needs will be met by cash on hand, operating cash flow due to projected reductions in distribution, capital expenditures and operation and maintenance expense, proceeds from commercial paper issuances and borrowings under our Revolving Credit Facility. COVID-19 has led to a significant disruption in the equity and debt capital markets, which could hinder our ability to raise new capital or obtain financing on acceptable terms. See “Recent Developments” above for further discussion of the impact of COVID-19. Our ability to generate cash flow is subject to a number of factors, some of which are beyond our control. See Part II, Item 1A. “Risk Factors” for further discussion.

Table of Contents
Working Capital
 
Working capital is the difference in our current assets and our current liabilities. Working capital is an indication of liquidity and potential need for short-term funding. The change in our working capital requirements are driven generally by changes in accounts receivable, accounts payable, commodity prices, credit extended to, and the timing of collections from, customers, the level and timing of spending for maintenance and expansion activity, and the timing of debt maturities. As of September 30, 2020, we had a working capital deficit of $271 million. The deficit is primarily due to $334 million of commercial paper outstanding as of September 30, 2020. We utilize our commercial paper program and Revolving Credit Facility to manage the timing of cash flows and fund short-term working capital deficits.

Operating Activities
 
The decrease of $148 million or 21%, in net cash provided by operating activities for the nine months ended September 30, 2020 as compared to the nine months ended September 30, 2019 was primarily driven by a decrease in net income of $394 million and a decrease of $8 million in the timing of cash receipts and disbursements and changes in other working capital assets and liabilities, partially offset by an increase in adjustments for non-cash items of $254 million.

Investing Activities
 
The decrease of $233 million, or 66%, in net cash used in investing activities for the nine months ended September 30, 2020 as compared to the nine months ended September 30, 2019 was primarily due to lower capital expenditures of $201 million, partially offset by an increase in proceeds from sale of $18 million due to the sale of the Partnership’s interest in the Bistineau Storage Facility, an increase in other investing cash flows of $12 million, an increase in return of investment in equity method affiliate of $1 million and an increase in proceeds from insurance of $1 million.

Financing Activities

Net cash used in financing activities increased $62 million, or 18%, for the nine months ended September 30, 2020 as compared to the nine months ended September 30, 2019. Our primary financing activities consist of the following:

Sources of Liquidity

As of September 30, 2020, our sources of liquidity included:
cash on hand;
cash generated from operations;
proceeds from commercial paper issuances; and
borrowings under our Revolving Credit Facility.

ATM Program

On May 12, 2017, the Partnership entered into an ATM Equity Offering Sales Agreement, pursuant to which the Partnership may issue and sell common units having an aggregate offering price of up to $200 million, by sales methods and at prices determined by market conditions and other factors at the time of our offerings. The registration statement filed with the SEC for the ATM Program expired on May 12, 2020, and the Partnership did not file a replacement registration statement.

Distributions
 
On November 3, 2020, the Board of Directors declared a quarterly cash distribution of $0.16525 per common unit on all of the Partnership’s outstanding common units for the period ended September 30, 2020. The distributions will be paid November 24, 2020 to unitholders of record as of the close of business on November 17, 2020. Additionally, the Board of Directors declared a quarterly cash distribution of $0.625 on the Partnership’s outstanding Series A Preferred Units. The distributions will be paid November 13, 2020 to unitholders of record as of the close of business on November 3, 2020.

Off-Balance Sheet Arrangements
 
We do not have any off-balance sheet arrangements.
 
Credit Risk
 
We are exposed to certain credit risks relating to our ongoing business operations. Credit risk includes the risk that our customers and other counterparties may encounter severe financial problems that could limit our ability to collect amounts owed to us or to enforce performance of other obligations under contractual arrangements. We examine the creditworthiness of customers and other counterparties to whom we extend credit and manage our exposure to credit risk through credit analysis, approval, limits and monitoring procedures, and for certain transactions, we may request letters of credit, prepayments or guarantees. The combination of reduction of cash flow resulting from declines in commodity prices, a reduction in borrowing bases under reserve-based credit facilities and the lack of availability of debt or equity financing may result in a significant reduction of our customers’ and other counterparties’ liquidity and limit their ability to make payment or perform on their obligations to us. For example, some of our customers have experienced significantly reduced liquidity as a result of the depressed commodity price environment caused by the oversupply of crude oil, NGLs and natural gas and the economic effects caused by the COVID-19 pandemic. Limitations on our ability to collect amounts owed to us or to enforce the performance of other obligations under contractual arrangements could result in the impairment of our assets, reduction of our operating cash flows and may also reduce or curtail our customers’ future use of our products and services, which could reduce our revenues.


Critical Accounting Policies and Estimates
 
The Partnership’s critical accounting policies and estimates are described in Critical Accounting Policies and Estimates within Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and Note 1 of the Notes to the Consolidated Financial Statements in Item 8. “Financial Statements and Supplementary Data” in our Annual Report. The accounting policies and estimates used in preparing our interim Condensed Consolidated Financial Statements for the three months ended September 30, 2020 are the same as those described in our Annual Report as modified for the adoption of new accounting standards and for the impairment of equity method affiliate investment disclosed in Item 1. “Financial Statements, Notes to Unaudited Condensed Consolidated Financial Statements.”


Item 3. Quantitative and Qualitative Disclosures About Market Risk

We are exposed to various market risks, including volatility in commodity prices and interest rates.

Commodity Price Risk
 
While we generate a substantial portion of our gross margin pursuant to fee-based contracts that include minimum volume commitments and/or demand fees, we are also directly and indirectly exposed to changes in the prices of natural gas, condensate and NGLs. Direct exposure includes the impact of commodity prices on our physical commodity positions, and indirect exposure includes the impact of commodity prices on the demand for midstream services due to changes in the exploration and production of commodities. The Partnership utilizes derivatives and forward commodity sales to mitigate the effects of price changes from our direct exposure to commodity price risks. We do not enter into risk management contracts for speculative purposes. For further information regarding our derivatives, see Note 10 of the Notes to the Condensed Consolidated Financial Statements.
 
Based on our forecast volumes, prices and contractual arrangements, we estimate approximately 10% of our total gross margin for the twelve months ended December 31, 2020 is directly exposed to changes in commodity prices, excluding the impact of hedges and contractual floors related to commodity prices in certain agreements. Since September 30, 2020, we have entered into additional derivative contracts to further manage our exposure to commodity price risk for the remaining three months ending December 31, 2020.

Our direct exposure to commodity price risk is estimated as the potential loss in value resulting from a hypothetical 10% decline in prices over the next three months. Based on a sensitivity analysis regarding our direct commodity exposure, a 10% decrease in prices from forecast levels would decrease net income by approximately $3 million for natural gas and ethane and $2 million for NGLs (other than ethane) and condensate, excluding the impact of hedges, for the remaining three months ending December 31, 2020.

The impact of the ongoing COVID-19 pandemic and the economic effects of the pandemic have resulted in a significant decrease in the price of natural gas, NGL and crude oil. The economic effects of the COVID-19 pandemic exacerbated pre-existing price declines due to oversupply. These events may negatively impact our financial condition and results of operations as a result of our direct and indirect exposure to commodity prices. Please see Item 2. “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Recent Developments” for further discussion.

Interest Rate Risk
 
Our current interest rate risk exposure is related primarily to our debt portfolio. Our debt portfolio includes senior notes with a fixed rate of interest, which mitigates the impact of fluctuations in interest rates. Future issuances of long-term debt could be impacted by increases in interest rates, which could result in higher interest costs. Borrowings under our 2019 Term Loan Agreement and any issuances under our commercial paper program are at a variable interest rate and expose us to the risk of increasing interest rates. The Partnership utilizes derivatives to mitigate the risk of interest rate changes. We do not enter into risk management contracts for speculative purposes. For further information regarding our derivatives, see Note 10 of the Notes to the Condensed Consolidated Financial Statements.

Based upon the $1.1 billion outstanding borrowings under commercial paper and 2019 Term Loan Agreement as of September 30, 2020, excluding the impact of hedges and holding all other variables constant, a 100 basis-point, or 1%, increase in interest rates would increase our annual interest expense by approximately $11 million. For further information regarding our interest rates, see Note 9 of the Notes to the Condensed Consolidated Financial Statements.


Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our chief executive officer and chief financial officer, has evaluated the effectiveness of our disclosure controls and procedures (as such term is defined in Rules 13a-15(e) under the Exchange Act) as of September 30, 2020. Based on such evaluation, our management has concluded that, as of September 30, 2020, our disclosure controls and procedures are designed and effective to ensure that information required to be disclosed in our reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified by the SEC’s rules and forms and that information is accumulated and communicated to our management, including its principal executive officer and principal financial officer, or persons performing similar functions, as appropriate, to allow timely decisions regarding required disclosure.

52

Table of Contents
In designing and evaluating our disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable, and not absolute, assurance that the objectives of the control system will be met. In addition, the design of any control system is based in part upon certain assumptions about the likelihood of future events and the application of judgment in evaluating the cost-benefit relationship of possible controls and procedures. Because of these and other inherent limitations of control systems, there is only reasonable assurance that our controls will succeed in achieving their goals under all potential future conditions.

Changes in Internal Controls Over Financial Reporting

There were no changes in our internal controls over financial reporting during the quarter ended September 30, 2020, that have materially affected, or that are reasonably likely to materially affect, our internal control over financial reporting. We have not experienced any material impact to our internal controls over financial reporting despite the fact that many of our employees are working remotely due to the COVID-19 pandemic. We are continually monitoring and assessing the effects of the COVID-19 situation on our internal controls to minimize the impact on their design and operating effectiveness.
