NOTES TO THE UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
 

(1) Summary of Significant Accounting Policies

Organization

Enable Midstream Partners, LP (the Partnership) is a Delaware limited partnership whose 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 gathering and processing services to our producer customers and crude oil, condensate and produced water gathering services to our producer and refiner 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. 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. 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 March 31, 2021, 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 March 31, 2021, the Partnership owned a 50% interest in SESH. See Note 8 for further discussion of SESH. For the three months ended March 31, 2021, the Partnership owned a 50% ownership in Atoka and consolidated Atoka in the accompanying 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 the accompanying Condensed Consolidated Financial Statements as EOCS acted as the managing member of ESCP and had control over the operations of ESCP.

Merger Agreement

On February 17, 2021, the Partnership and Energy Transfer announced their entry into a Merger Agreement, whereby the Partnership will be acquired by Energy Transfer in an all-equity transaction, including the assumption of debt and other liabilities. Under the terms of the Merger Agreement, which has been unanimously approved by the Boards of Directors of both companies, Partnership common unitholders will receive 0.8595 of an Energy Transfer common unit for each Partnership common unit. Each of the Partnership’s Series A Preferred Units will be exchanged for 0.0265 Series G preferred units of Energy Transfer. The transaction will also include a $10 million cash payment for the Partnership’s general partner.

Generally, the Merger, including the receipt of equity consideration by common unitholders is expected to be treated as a tax-free transaction subject to certain exceptions as described in a Registration Statement on Form S-4 filed by Energy Transfer. The transaction, which is expected to close in mid-2021, is subject to customary closing conditions. CenterPoint Energy and OGE Energy, who collectively own approximately 79% of the outstanding Partnership common units, delivered their consents to the transaction. The Merger Agreement includes certain customary restrictions on the Partnership until closing of the Merger, such as limitations on distributions, equity issuances, and incurring and prepaying indebtedness. If the Merger does not occur, under certain circumstances, the Partnership may be required to pay Energy Transfer a termination fee of $97.5 million. Until the approval by unitholders and subsequent closing, we must continue to operate the Partnership as a stand-alone company.

Table of Contents
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.

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.

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$4 $1 
Other assets3 3 
Total Allowance for doubtful accounts$7 $4 

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 $1 million and $6 million during the three months ended March 31, 2021 and 2020, respectively.

Impairment of Long-Lived Assets (including Intangible Assets)

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.

Impairment of Goodwill

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.


(2) New Accounting Pronouncements

Reference Rate Reform

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 adopted ASU 2020-04 during the year ended December 31, 2020. The implementation had no material impact on the Consolidated Financial Statements and related disclosures.

In January 2021, the FASB issued ASU No. 2021-01, “Reference Rate Reform (Topic 848): Scope.” This standard clarifies that certain optional expedients and exceptions in ASC 848 for contract modifications and hedge accounting apply to derivatives that are affected by the discounting transition. ASU 2021-01 also amends the expedients and exceptions in ASC 848 to capture the incremental consequences of the scope clarification and to tailor the existing guidance to derivative instruments affected by the discounting transition. ASU 2021-01 was effective upon issuance and generally can be applied through December 31, 2022. The Partnership adopted ASU 2021-01 during three months ended March 31, 2021. The implementation had no material impact on the Condensed Consolidated Financial Statements and related disclosures.

(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 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 were 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 three months ended March 31, 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 had remained significantly lower than pre-pandemic levels. Amid such crude oil, NGL and natural gas price declines, producers had 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 had 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 three months ended March 31, 2020. The Partnership had no goodwill recorded as of March 31, 2021 and December 31, 2020.


(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.

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 $2 million and $6 million during the three months ended March 31, 2021 and 2020, respectively, associated with these service agreements.

The Partnership includes equity in earnings of equity method affiliate, net under the Other Income (Expense) caption in the Condensed Consolidated Statements of Income.

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 $214 million and $250 million outstanding under our commercial paper program at March 31, 2021 and December 31, 2020, respectively. As of March 31, 2021, the weighted average interest rate for the outstanding commercial paper was 0.73%.

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 March 31, 2021, there were no principal advances, $3 million letters of credit outstanding and our available borrowing capacity was approximately $980 million under our Revolving Credit Facility.

20

Table of Contents
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 March 31, 2021, 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 March 31, 2021, 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.

2019 Term Loan Agreement

On January 29, 2019, the Partnership entered into an unsecured term loan agreement with Bank of America, N.A., as administrative agent, and the several lenders thereto. As of March 31, 2021, there was $800 million outstanding under the 2019 Term Loan Agreement. The 2019 Term Loan Agreement has a scheduled maturity date of January 29, 2022, but contains an option, which may be exercised up to two times, to extend the maturity date for an additional one-year term. The 2019 Term Loan Agreement provides that outstanding borrowings bear interest at the eurodollar rate and/or an alternate base rate, at the Partnership’s election, plus an applicable margin. The applicable margin is based on the Partnership’s credit ratings. The applicable margin shall equal, (1) in the case of interest rates determined by reference to the eurodollar rate, between 0.75% and 1.50% per annum and (2) in the case of interest rates determined by reference to the alternate base rate, between 0% and 0.50% per annum. As of March 31, 2021, the applicable margin for LIBOR-based advances under the 2019 Term Loan Facility was 1.25% based on the Partnership’s credit ratings. As of March 31, 2021, the weighted average interest rate of the 2019 Term Loan Agreement was 2.08%, including the impact of the associated interest rate derivatives designated as hedging instruments for accounting purposes.

Senior Notes

As of March 31, 2021, the Partnership’s debt included the 2024 Notes, 2027 Notes, 2028 Notes, 2029 Notes and 2044 Notes, which had $7 million of unamortized discount and $19 million of unamortized debt expense at March 31, 2021, resulting in effective interest rates of 4.01%, 4.56%, 5.19%, 4.30% and 5.08%, respectively, during the three months ended March 31, 2021. In March 2020, the Partnership’s EOIT Senior Notes matured and were paid using proceeds from the Revolving Credit Facility.

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 March 31, 2021, under these obligations, the Partnership had posted no cash collateral related to natural gas swaps and swaptions, crude oil swaps and swaptions and NGL swaps and $1 million of additional 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 months ended March 31, 2021, there were no transfers between levels. As of March 31, 2021, 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.

(1)    Borrowing capacity is effectively reduced by our borrowings outstanding under the commercial paper program. $214 million and $250 million of commercial paper was outstanding as of March 31, 2021 and December 31, 2020, respectively.

The fair value of the Partnership’s Revolving Credit Facility, 2019 Term Loan Agreement, 2024 Notes, 2027 Notes, 2028 Notes, 2029 Notes, and 2044 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 March 31, 2021, no material fair value adjustments or fair value measurements were required for these non-financial assets or liabilities.

Based upon review of forecast undiscounted cash flows as of March 31, 2021, all of the asset groups were considered recoverable. Based upon review for other than temporary declines in fair value, the investment in equity method affiliate was considered recoverable. 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.

Contracts with Master Netting Arrangements
 
As of March 31, 2021, the Partnership’s Level 2 interest rate derivatives are recorded as liabilities with no netting adjustments.

Corporate services and seconded employees

The Partnership receives services and support functions from each of CenterPoint Energy and OGE Energy under services agreements for an initial term that ended on April 30, 2016. The services agreements automatically extend year-to-year at the end of the initial term, unless terminated by the Partnership with at least 90 days’ notice prior to the end of any extension. Additionally, the Partnership may terminate the services agreements at any time with 180 days’ notice, if approved by the Board of Enable GP. The Partnership reimburses CenterPoint Energy and OGE Energy for these services up to annual caps, which for 2021 are both less than $1 million.

As of March 31, 2021, the Partnership had certain employees who are participants under OGE Energy’s defined benefit and retiree medical plans, who will remain seconded to the Partnership, subject to certain termination rights of the Partnership and OGE Energy. The Partnership’s reimbursement of OGE Energy for seconded employee costs arising out of OGE Energy’s defined benefit and retiree medical plans is fixed at actual cost subject to an annual cap of $5 million until secondment is terminated.

(14) Commitments and Contingencies
 
The Partnership is 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 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 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 for deliveries to the Godley Plant in Johnson County, Texas. As of March 31, 2021, the Partnership estimates the remaining associated minimum volume commitment fee to be $164 million. Minimum volume commitment fees are expected to be $15 million for the remainder of 2021, $23 million per year from 2022 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. The Partnership estimates the cost to complete the Gulf Run Pipeline project would be as much as $540 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 2020 Notes to 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 and (ii) transportation and storage. Our gathering and processing segment primarily provides natural gas gathering and processing services to our producer customers and crude oil, condensate and produced water gathering services to our producer and refiner 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.

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

The following discussion and analysis should be read in conjunction with our unaudited Condensed Consolidated Financial Statements and the related notes included herein and our audited Consolidated Financial Statements for the year ended December 31, 2020, included in our Annual Report. The following discussion contains forward-looking statements that reflect our future plans, estimates, beliefs and expected performance. The forward-looking statements are dependent upon events, risks and uncertainties that may be outside our control, including risks resulting from the ongoing COVID-19 pandemic and the economic effects of the pandemic. Our actual results could differ materially from those discussed in these forward-looking statements. Please read “Forward-Looking Statements.” In light of these risks, uncertainties and assumptions, the forward-looking events discussed may not occur.

Table of Contents
Overview

Enable Midstream Partners, LP owns, operates and develops midstream energy infrastructure assets strategically located to serve our customers. We are traded on the NYSE 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.


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. We expect that our liquidity and capital resource needs will be met by our sources of liquidity, which as of March 31, 2021, included cash on hand, operating cash flow, proceeds from commercial paper issuances, borrowings under our revolving credit facility, debt issuances and the issuance of equity. For more information on our commercial paper program, our revolving credit agreement, our other outstanding debt agreements and preferred equity, please see Note 6 “Partners’ Equity” and Note 9 “Debt” in the Notes to the Unaudited Condensed Consolidated Financial Statements under Item 1. “Financial Statements.”

Cash on hand and operating cash flow can be subject to fluctuations due to trends and uncertainties that are beyond our control. Likewise, our ability to issue commercial paper, equity and debt and our ability to obtain credit facilities on favorable terms may be impacted by a variety of market factors as well as fluctuations in our results of operations. For more information on conditions impacting our liquidity and capital resources, see “Results of Operations—Trends and Uncertainties Affecting Results of Operations.” For further discussion of risks related to our liquidity and capital resources, see Item 1A. “Risk Factors” in our Annual Report.
 
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
31

Table of Contents
March 31, 2021, we had a working capital deficit of $885 million. The deficit is primarily due to the classification of $800 million of the 2019 Term Loan Agreement as Current portion of long-term debt as of March 31, 2021 as well as $214 million of commercial paper outstanding as of March 31, 2021. 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 increase of $23 million or 12%, in net cash provided by operating activities for the three months ended March 31, 2021 as compared to the three months ended March 31, 2020 was primarily driven by an increase in net income of $60 million, partially offset by a decrease in adjustments for non-cash items of $26 million and a decrease of $11 million in the timing of cash receipts and disbursements and changes in other working capital assets and liabilities.

Investing Activities
 
The increase of $27 million, or 56%, in net cash used in investing activities for the three months ended March 31, 2021 as compared to the three months ended March 31, 2020 was primarily due to higher capital expenditures of $26 million, a decrease in other investing cash flows of $1 million and a decrease in return of investment in equity method affiliate of $1 million, partially offset by an increase in proceeds from sale of assets of $1 million.

Financing Activities

Net cash used in financing activities decreased $33 million, or 22%, for the three months ended March 31, 2021 as compared to the three months ended March 31, 2020. Our primary financing activities consist of the following:

Distributions
 
On April 26, 2021, 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 March 31, 2021. The distributions will be paid May 25, 2021 to unitholders of record as of the close of business on May 13, 2021. Additionally, the Board of Directors declared a quarterly cash distribution of $0.5873 on the Partnership’s outstanding Series A Preferred Units. The distributions will be paid May 14, 2021 to unitholders of record as of the close of business on April 26, 2021.

Trends Affecting Liquidity and Capital Resources

Borrowing Capacity

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
32

Table of Contents
day of each fiscal quarter of less than or equal to 5.00 to 1.00. As of March 31, 2021, our available borrowing capacity under our Revolving Credit Facility was approximately $980 million due to this financial covenant, prior to invoking any amounts related to Qualified Project EBITDA Adjustments (as defined in the Revolving Credit Facility). However, we believe that we will have sufficient cash flow and borrowing capacity to fully fund our business.

Trends and Uncertainties Affecting Results of Operations

Energy Transfer Merger

On February 16, 2021, we entered into a definitive Merger Agreement with Energy Transfer, pursuant to which, among other things, all outstanding common units of the Partnership will be acquired by Energy Transfer in an all-equity transaction, including the assumption of debt and other liabilities, subject to the conditions of the Merger Agreement.

Under the terms of the Merger Agreement, our common unitholders will receive 0.8595 of one common unit representing limited partner interests in Energy Transfer for each common unit of the Partnership. In addition, each issued and outstanding Series A Preferred Unit of the Partnership will be exchanged for 0.0265 of an Energy Transfer Series G preferred unit, and Energy Transfer will make a $10 million cash payment to the owners of the Partnership’s general partner for the limited liability company interests in Enable GP. The transaction was approved by the boards of directors of the general partners of both partnerships and the Conflicts Committee of our Board of Directors. The transaction is subject to the receipt of the required approvals from the holders of a majority of our common units, regulatory approvals, and other customary closing conditions.

Pursuant to a consent statement/prospectus dated April 8, 2021, which was included as part of a Registration Statement on Form S-4 filed by Energy Transfer, the Partnership solicited written consents from its common unitholders to approve the Merger Agreement and, on a non-binding, advisory basis, the compensation that will or may become payable to the Partnership’s named executive officers in connection with the transactions contemplated by the Merger Agreement. Pursuant to previously disclosed support agreements, CenterPoint Energy and OGE Energy, who collectively own approximately 79.2% of the Partnership’s common units, delivered written consents approving the Merger Agreement and, on a non-binding, advisory basis, the transaction-related compensation proposal. While the consents of CenterPoint Energy and OGE Energy are sufficient to approve the transaction, the Partnership is requesting that all of its common unitholders approve the Merger and other proposals outlined in the consent statement/prospectus by executing and returning the written consents furnished therewith.

The Merger is anticipated to close in mid-2021, subject to the satisfaction of customary closing conditions, including Hart-Scott-Rodino clearance. We cannot provide any assurance that the combination will be completed on the terms or timeline currently contemplated, or at all. The above is a summary of the material terms of the Merger and is qualified in its entirety by reference to the Registration Statement on Form S-4 (which became effective on April 7, 2021) filed by Energy Transfer.

COVID-19 Pandemic

Throughout the COVID-19 pandemic, 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. In compliance with Center for Disease Control guidance, we implemented strategies to protect the health and safety of our workers, including virtual symptom screening, social distancing, wearing masks, limiting non-essential travel, and, where possible, utilizing remote working. In April 2021, we began returning additional employees to the workplace who had been working remotely. We will continue to monitor for the resurgence of COVID-19 in our workplaces and in the communities where our employees are located and adjust our strategies accordingly.

Commodity Price Environment

Our business is impacted by commodity prices, which have continued to experience significant volatility. Commodity prices impact the drilling and production of natural gas and crude oil in the areas served by our systems, and the volumes on our systems are impacted by the amount of drilling and production in the areas we serve. Both our gathering and processing segment and our transportation and storage segment can be affected by drilling and production. For more information regarding the impact of commodity prices, drilling and production on the volumes on our systems as well as our exposure to commodity prices under our processing arrangements, see Item 1A. “Risk Factors—Risks Related to Our Business” in our Annual Report.

33

Table of Contents
We have attempted to mitigate the impact of commodity prices on our business by entering into hedges, focusing on contracting fee-based business and converting existing commodity-based contracts to fee-based contracts. For additional information regarding our commodity price risk, see Item 7A. “Quantitative and Qualitative Disclosures About Market RiskCommodity Price Risk” in our Annual Report.

During the three months ended March 31, 2021 as compared to the three months ended March 31, 2020, our revenues and gross margin increased. These increases resulted primarily from the impact of the February 2021 Winter Storm Uri on the areas in which we operate. The winter storm temporarily increased the price of natural gas, which increased our proceeds from product sales. The winter storm also temporarily increased the demand for natural gas for heating, which resulted in imbalance penalties for customers on our gathering and processing and transportation and storage systems for customers who failed to balance actual receipts and deliveries at nominated and confirmed levels. The results of our most recent period may not be indicative of our future results because of the temporary effects of the winter storm. For more information on our results, see “—Financial Results” below.

During the three months ended March 31, 2021 as compared to the three months ended March 31, 2020, our natural gas gathered volumes, processed volumes, transported volumes, and crude oil and condensate gathered volumes decreased. These decreases resulted primarily from reductions in the production of natural gas, NGLs and crude oil. The reductions in supply of 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. 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. For more information on our results, see “—Financial Results” below.

Recent Developments

Dakota Access Pipeline

On July 6, 2020, the federal district court for the District of Columbia (the “District Court”) issued an order vacating an easement, that was issued by the U.S. Corps of Engineers and which allowed Dakota Access Pipeline to cross the Missouri River, pending the completion of an environmental impact analysis for the pipeline. Although the pipeline currently continues to operate, the District Court is considering whether to order the pipeline shut down during the pendency of the environmental review. Substantially all of the crude oil gathered by our Williston Basin crude oil systems is delivered indirectly for transport to Dakota Access Pipeline. A shutdown of Dakota Access Pipeline could occur if the Corps does not grant an easement following the completion of the environmental impact statement. 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 Enbridge North Dakota 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. We are unable to predict whether any such pipeline will be shut down, 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.

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.

State district courts in Oklahoma, applying the analysis in the U.S. Supreme Court’s ruling regarding the Muscogee (Creek) Nation, have ruled that the Cherokee, Chickasaw, Seminole and Choctaw reservations likewise have not been disestablished. On October 1, 2020, the EPA granted approval to the State of Oklahoma under Section 10211(a) of the Safe, Accountable, 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, subject to certain exceptions, effectively extending 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 ruling. For more information, see the “Five Nations Reservations” disclosure in our Annual Report. At this time, we cannot predict how these issues may ultimately be resolved.

Suspension of Leases and Permits on Federal Lands

On January 20, 2021, the Acting Secretary of the U.S. Department of the Interior issued an order that, among other things, imposed a temporary suspension on the issuance of fossil fuel authorizations, including leases and permits on federal lands. Although the order says it does not limit existing operations under valid leases, on January 27, 2021, President Biden signed an executive order suspending new oil and gas leasing on federal lands, pending completion of a review of the federal government’s oil and gas permitting and leasing practices. Less than 2% of acreage dedicated to the Partnership falls on federal lands, with most of our federal land acreage dedications located in the Williston Basin.

Regulatory Compliance

The Pipeline and Hazardous Materials Safety Administration is expected to issue several rules in 2021, including but not limited to: 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. Other agencies, such as the EPA, are also expected to issue new regulations that may impact our operations. While we cannot predict the outcome of pending or future legislative or regulatory initiatives, we anticipate that pipeline safety and environmental requirements will continue to become more stringent over time. As a result, we may incur significant additional costs to comply with the pending regulations, and any other future laws and regulations, which could have a material impact on our costs of and revenues from operations.

FERC Update

On February 18, 2021, FERC issued a renewed Notice of Inquiry (NOI) seeking input on potential revisions to its current policy statement on the certification of new natural gas transmission facilities. The NOI supplements a 2018 NOI issued by FERC on the same topic. Comments on the NOI are due on May 26, 2021. We are unable to predict what, if any, changes may be proposed as a result of the NOI that would affect our transportation and storage segment or when such proposals, if any, might become effective.

Gathering and Processing

Three months ended March 31, 2021 compared to three months ended March 31, 2020. Our gathering and processing segment reported operating income of $62 million for the three months ended March 31, 2021 compared to operating income of $72 million for the three months ended March 31, 2020. The difference of $10 million in operating income between periods was primarily due to a $40 million decrease in gross margin, partially offset by $28 million of property, plant and equipment and goodwill impairments recognized in 2020 and a $2 million decrease in operation and maintenance and general and administrative expenses.

Our gathering and processing segment revenues increased $147 million. The increase was primarily due to the following:
Product Sales:
revenues from NGL sales increased $130 million primarily due to an increase in the average realized sales price from higher average market prices for NGL products combined with higher recoveries of ethane, partially offset by lower processed volumes and
revenues from natural gas sales increased $56 million due to higher average sales prices.
These increases were partially offset by:
changes in the fair value of natural gas, condensate and NGL derivatives decreased $19 million and
realized losses on natural gas, condensate and NGL derivatives, which increased $14 million.
Service Revenues:
processing service revenues increased $3 million due to higher consideration received from percent-of-proceeds, percent-of-liquids and keep-whole processing arrangements due to higher average market prices, partially offset by lower processed volumes under fee-based arrangements.
These increases were partially offset by:
natural gas gathering revenues decreased $8 million due to lower gathered volumes, inclusive of volume curtailments and production freeze-offs related to Winter Storm Uri, partially offset by higher assessed producer imbalance penalties and
crude oil, condensate and produced water gathering revenue, which decreased $1 million primarily due to a decrease in gathered crude oil and condensate volumes in the Anadarko Basin, partially offset by an increase in gathered crude oil volumes in the Williston Basin.

37

Table of Contents
Our gathering and processing segment gross margin decreased $40 million. The decrease was primarily due to the following:
changes in the fair value of natural gas, condensate and NGL derivatives decreased $19 million,
realized losses on natural gas, condensate and NGL derivatives, which increased $14 million,
revenues from natural gas sales less the cost of natural gas decreased approximately $10 million due to higher intra month natural gas purchase costs during Winter Storm Uri,
natural gas gathering fees decreased $8 million due to lower gathered volumes, inclusive of volume curtailments and production freeze-offs related to Winter Storm Uri, partially offset by higher assessed producer imbalance penalties, and
crude oil, condensate and produced water gathering revenues decreased $1 million primarily due to a decrease in gathered crude oil and condensate volumes in the Anadarko Basin, partially offset by an increase in gathered crude oil volumes in the Williston Basin.
These decreases were partially offset by:
revenues from NGL sales less the cost of NGLs increased $9 million primarily due to an increase in the average realized sales price from higher average market prices for NGL products combined with higher recoveries of ethane, partially offset by lower processed volumes and
processing service fees increased $3 million due to higher consideration received from percent-of-proceeds, percent-of-liquids and keep-whole processing arrangements due to higher average market prices, partially offset by lower processed volumes under fee-based arrangements.

Our gathering and processing segment operation and maintenance and general and administrative expenses decreased $2 million. The decrease was primarily due to a $6 million decrease in payroll-related costs as a result of lower headcount, a $3 million decrease in field equipment rentals and a $1 million decrease due to insurance proceeds partially offset by remediation costs associated with our Williston Basin operations. These decreases were partially offset by a $7 million increase in professional services primarily due to transaction costs related to the pending merger with Energy Transfer and a $1 million increase due to lower capitalized overhead costs.

During the three months ended March 31, 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. 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.

Transportation and Storage

Three months ended March 31, 2021 compared to three months ended March 31, 2020. Our transportation and storage segment reported operating income of $144 million for the three months ended March 31, 2021 compared to operating income of $74 million for the three months ended March 31, 2020. The difference of $70 million in operating income between periods was primarily due to a $69 million increase in gross margin, $3 million decrease in operation and maintenance and general and administrative expenses, partially offset by a $2 million increase in depreciation and amortization.

Our transportation and storage segment revenues increased $248 million. The increase was primarily due to the following:
Product Sales:
revenues from natural gas sales increased $257 million primarily due to higher average sales prices,
volume-dependent transportation and storage revenues increased $6 million due to an increase in assessed shipper imbalance penalties, partially offset by lower off-system intrastate transported volumes due to decreased production activity in the Anadarko Basin, inclusive of disruptions in natural gas supply associated with Winter Storm Uri, and the recognition in 2020 of $1 million of revenue upon the settlement of the MRT rate case with no comparable item in 2021, and
revenues from NGL sales increased $1 million due to higher average sales prices, partially offset by lower volumes.
38

Table of Contents
These increases were partially offset by changes in the fair value of natural gas derivatives, which decreased $1 million.
Service Revenues:
firm transportation and storage services decreased $15 million due to the recognition in 2020 of $16 million of previously reserved revenue upon the settlement of the MRT rate case with no comparable item in 2021, partially offset by higher interstate contracted capacity.

Our transportation and storage segment gross margin increased $69 million. The increase was primarily due to the following:
system management activities increased $74 million primarily due to higher average natural gas sales prices,
volume-dependent transportation and storage revenues increased $6 million due to an increase in assessed shipper imbalance penalties, partially offset by lower off-system intrastate transported volumes due to decreased production activity in the Anadarko Basin, inclusive of disruptions in natural gas supply associated with Winter Storm Uri, and the recognition in 2020 of $1 million of revenue upon the settlement of the MRT rate case with no comparable item in 2021, and
a $5 million reduction in lower of cost or net realizable value adjustments related to natural gas storage inventories.
These increases were partially offset by:
firm transportation and storage services decreased $15 million due to the recognition in 2020 of $16 million of previously reserved revenue upon the settlement of the MRT rate case with no comparable item in 2021, partially offset by higher interstate contracted capacity and
changes in the fair value of natural gas derivatives, which decreased $1 million.

Our transportation and storage segment operation and maintenance and general and administrative expenses decreased $3 million. The decrease was primarily driven by a $3 million decrease in payroll-related costs as a result of lower headcount and a $3 million decrease in operation and maintenance outside services. These decreases were partially offset by a $3 million increase in the allowance for doubtful accounts.

Our transportation and storage segment depreciation and amortization increased $2 million primarily due to revised estimates of remaining useful lives for certain assets.

Net Income Attributable to Limited Partners. We reported net income attributable to limited partners of $164 million in the three months ended March 31, 2021 compared to net income attributable to limited partners of $112 million in the three months ended March 31, 2020. The increase in net income attributable to limited partners of $52 million was primarily attributable to an increase in operating income of $60 million and a decrease in interest expense of $5 million, partially offset by an $8 million change in net income (loss) attributable to noncontrolling interest in the prior year and a decrease in equity in earnings of equity method affiliate, net of $5 million in the three months ended March 31, 2021.

Equity in Earnings of Equity Method Affiliate, net. Equity in earnings of equity method affiliate, net decreased $5 million due to a decrease in revenues as a result of contract expirations, partially offset by an increase in amortization of the basis differential.

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

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.

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 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 March 31, 2021 are the same as those described in our Annual Report.


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 13% of our total gross margin for the twelve months ended December 31, 2021 is directly exposed to changes in commodity prices, excluding the impact of hedges and contractual floors related to commodity prices in certain agreements. Since March 31, 2021, we have entered into additional derivative contracts to further manage our exposure to commodity price risk for the remaining nine months ending December 31, 2021.

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 nine 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 $8 million for natural gas and ethane and $12 million for NGLs (other than ethane) and condensate, excluding the impact of hedges, for the remaining nine months ending December 31, 2021.

Interest Rate Risk
 
Our current interest rate risk exposure is related primarily to our debt portfolio and distributions on the Series A Preferred Units. 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 and distributions on our Series A Preferred Units 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 $1.0 billion outstanding borrowings under commercial paper and 2019 Term Loan Agreement as of March 31, 2021, 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 $10 million. For further information regarding our interest rates, see Note 9 of the Notes to the Condensed Consolidated Financial Statements.

Beginning February 18, 2021, distributions on the Series A Preferred Units, when declared, are calculated at a floating rate equal to the sum of the three-month LIBOR plus 8.5%. Based upon the $362 million outstanding under the Series A Preferred Units as of March 31, 2021, holding all variables constant, a 100 basis-point, or 1%, increase in interest rates would increase our Series A Preferred Unit annual distributions by $4 million. For further information regarding the Series A Preferred Units, see Note 6 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 March 31, 2021. Based on such evaluation, our management has concluded that, as of March 31, 2021, 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.

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 March 31, 2021, that have materially affected, or that are reasonably likely to materially affect, our internal control over financial reporting.
