ENABLE MIDSTREAM PARTNERS, LP
NOTES TO THE UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
 

(1) Summary of Significant Accounting Policies

Organization
 
Enable Midstream Partners, LP (Partnership) is a Delaware limited partnership formed on May 1, 2013 by CenterPoint Energy, OGE Energy and ArcLight. The Partnership’swhose 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, an interstatea 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, 2017,March 31, 2019, CenterPoint Energy held approximately 54.1%53.8% or 233,856,623 of the Partnership’s common units, and OGE Energy held approximately 25.7%25.5% or 110,982,805 of the Partnership’s common units. Additionally, CenterPoint Energy holds 14,520,000 Series A Preferred Units. See Note 4 for further information related to the 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 (Enable GP)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, 2017,March 31, 2019, the Partnership owned a 50% interest in SESH. See Note 68 for further discussion of SESH. For the three months ended March 31, 2019, 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, beginning November 1, 2018 through March 31, 2019, the Partnership owned 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.  

 TheseThe condensed consolidated financial statements and the related financial statement disclosuresnotes 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 and (d) acquisitions and dispositions of businesses, assets and other interests.
 
For a description of the Partnership’s reportable segments, see Note 14.16.


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.

Restricted CashDepreciation Expense

Restricted cash consistsThe Partnership completed a depreciation study for the Gathering and Processing and Transportation and Storage segments. Effective January 1, 2019, the new depreciation rates have been applied prospectively as a change in accounting estimate. The new depreciation rates did not result in a material change in depreciation expense or results of cash which is restricted by agreements with third parties. The Condensed Consolidated Balance Sheets have $14 million and $17 million of restricted cash as of September 30, 2017 and December 31, 2016, respectively.operations.

Accounts Receivable and 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 upon specific identification and estimates of future uncollectable amounts. On an ongoing basis, management evaluateswe evaluate our customers’ financial strength 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 at least quarterly, giving consideration to historical bad debt write-offs,credit losses, the aging of receivables, and specific customer circumstances that may impact their ability to pay the amounts due.due and current and forecasted economic conditions over the assets contractual lives. Based on this review, management determined that a $3$2 million allowance for doubtful accounts was required at each of September 30, 2017March 31, 2019 and December 31, 2016.2018.

Inventory

Natural gas inventory is held, through the transportation and storage segment, to provide operational support for the intrastate 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’s Inventory balance is net of $1 million and $4 million lower of cost or net realizable value adjustments as of March 31, 2019 and December 31, 2018, respectively.


(2) New Accounting Pronouncements

Accounting Standards to be Adopted in Future Periods

Revenue from Contracts with CustomersFinancial Instruments—Credit Losses

In May 2014,June 2016, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers2016-13, “Financial Instruments—Credit Losses (Topic 606),326): Measurement of Credit Losses on Financial Instruments.which supersedes the revenue recognition requirements in “Revenue Recognition (Topic 605).” Topic 606 isThis standard requires entities to measure all expected credit losses of financial assets held at a reporting date based on historical experience, current conditions, and reasonable and supportable forecasts in order to record credit losses in a more timely manner. ASU 2016-13 also amends the core principle that revenue is recognized to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchangeaccounting for those goods or services. Topic 606 also requires additional disclosure about the nature, amount, timingcredit losses on available-for-sale debt securities and uncertainty of revenue and cash flows arising from contractspurchased financial assets with customers, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract.

Topic 606credit deterioration. The standard is effective for fiscal yearsinterim and annual reporting periods beginning after December 15, 2017. We continue to evaluate the impact this standard will have on the2019, although early adoption is permitted for interim and annual periods beginning after December 15, 2018. The Partnership which includes our review of contracts and transaction types across all our business segments. We continue to review the potential impact on certain commodity-based gathering and processing contract types. Due to this ongoing analysis, we cannot yet determine the quantitative impact on revenues or cost of natural gas and natural gas liquids fromdoes not expect the adoption of Topic 606, however, we currently believe the adoption will notthis standard to have a material impact on operating income or net income. Basedour Condensed Consolidated Financial Statements and related disclosures.

Intangibles—Goodwill and Other

In January 2017, the FASB issued ASU No. 2017-04, “Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment.” This standard requires entities to test goodwill for impairment by eliminating Step 2 from the goodwill impairment test. The standard is effective for interim and annual reporting periods beginning after December 15, 2019. The Partnership does not expect the adoption of this standard to have a material impact on our analysisCondensed Consolidated Financial Statements and related disclosures.


Fair Value Measurement—Disclosure Framework-Changes to date, we do not expect material changesthe Disclosure Requirements for Fair Value Measurement

In August 2018, the FASB issued ASU No. 2018-13, “Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement” which focuses on improving the effectiveness of disclosures in the timingnotes to the financial statements by facilitating clear communication of revenue recognition or our accounting policies. We continuethe information required by U.S. GAAP that is most important to developusers of each entity’s financial statements. The standard is effective for interim and evaluate our Topic 606 disclosures, as well as changes to internal controls necessary for adoption.annual reporting periods beginning after December 15, 2019, although early adoption is permitted. The Partnership willexpects to adopt the revenue recognition standardthese standards in the first quarter of 20182020 and expectscontinues to adopt Topic 606 usingevaluate the modified retrospective method. other impacts of the new standards on our Condensed Consolidated Financial Statements and related disclosures.

LeasesIntangibles—Goodwill and Other—Internal-Use Software

In February 2016,August 2018, the FASB issued ASU No. 2018-15, “Intangibles—Goodwill and Other—Internal-Use Software: Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract”, which aims to reduce complexity in the accounting for costs of implementing a cloud computing service arrangement. ASU No. 2018-15 aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. The standard is effective for interim and annual periods beginning after December 15, 2019. The Partnership does not expect the adoption of this standard to have a material impact on our Condensed Consolidated Financial Statements and related disclosures.

Collaborative Arrangements

In November 2018, the FASB issued ASU No. 2018-18, “Collaborative Arrangements (Topic 808): Clarifying the Interaction between Topic 808 and Topic 606.” This standard resolves the diversity in practice concerning the manner in which entities account for transactions on the basis of their view of the economics of the collaborative arrangement. The amendments (1) clarify that certain transactions between collaborative participants should be accounted for as revenue under topic 606 when the collaborative participant is a customer in the context of the unit of account; (2) add unit-of-account guidance in Topic 808 to align with the guidance in Topic 606; and (3) clarify that in a transaction that is not directly related to sales to third parties, presenting the transaction as revenue would be precluded if the collaborative participant counterparty was not a customer. The standard is effective for interim and annual periods beginning after December 15, 2019. The Partnership does not expect the adoption of this standard to have a material impact on our Condensed Consolidated Financial Statements and related disclosures.

(4) Leases

On January 1, 2019, the Partnership adopted ASU 2016-02, “Leases (Topic(ASC 842).” This standard requires, among other things, that lessees recognize the following for all leases (with the exception of short-term leases) at the commencement date: (1) a lease liability, which is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis; and (2) a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. Lessees and lessors must apply a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The Partnership expectshas applied the standard to adopt this standardonly contracts that were not expired as of January 1, 2019.

The Partnership elected the optional transition practical expedient to not evaluate land easements that exist or expire before the Partnership's adoption of ASC 842 and that were not previously accounted for as leases under ASC 840. The Partnership elected the optional transition practical expedient to not reassess whether any expired or existing contracts are or contain leases, the lease classification for any expired or existing leases and initial direct costs for any existing leases. Upon adoption, we increased our asset and liability balances on the Condensed Consolidated Balance Sheets by approximately $35 million due to the required recognition of right-of-use assets and corresponding lease liabilities for all lease obligations that were classified as operating leases. The Partnership did not recognize a material cumulative adjustment to the Condensed Consolidated Statement of Partners’ Equity and we did not have any material changes in the first quartertiming of 2019expense recognition or our accounting policies.

Our lease obligations are primarily comprised of rentals of field equipment and buildings, which are recorded as Operation and maintenance and General and administrative expenses in the Partnership’s Condensed Consolidated Statements of Income. Other than the contractual terms for each lease obligation, the key inputs for our calculations of the initial right-of-use assets and corresponding lease liabilities are the expected remaining life and applicable discount rate. Field equipment has an expected lease term of three to five years, with contractual base terms of one to three years followed by month-to-month renewals. Field equipment rental arrangements do not generally contain any significant variable lease payments. While certain arrangements may include lower standby rates, field equipment is generally anticipated to be in use for all of its expected lease term. Buildings have an expected lease term of seven to ten years, which is currently evaluating the impactsame as the contractual base term. Building rental arrangements contain market-based renewal options of this standard on our Condensed Consolidated Financial Statementsup to 15 years. Variable lease payments for buildings are generally comprised of costs for utilities, maintenance and related disclosures. In connection with our assessment work, we formed an implementation work team andbuilding management services. There are continuing our review of our contracts relative to the provisionsno variable lease payments due under building rental arrangements until July 1, 2019, after which amounts will be due monthly. The Partnership is generally not aware of the implicit rate for either field equipment or building rental arrangements, so discount rates are based upon the expected term of each arrangement and the Partnership’s uncollateralized borrowing rate associated with the expected term at the time of lease standard.

Financial Instruments—Credit Losses

In June 2016,inception. As of March 31, 2019, the FASB issued ASU No. 2016-13, “Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” This standard requires entities to measure all expected credit losses of financial assets held at a reporting date based on historical experience, current conditions,weighted average remaining lease term is 4.2 years and reasonable and supportable forecasts in order to

record credit losses in a more timely matter. ASU 2016-13 also amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. The standardweighted average discount rate is effective for interim and annual reporting periods beginning after December 15, 2019, although early adoption is permitted for interim and annual periods beginning after December 15, 2018. The Partnership does not expect the adoption of this standard to have a material impact on our Condensed Consolidated Financial Statements and related disclosures.

Income Taxes

In October 2016, the FASB issued ASU No. 2016-16, “Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory.” This standard requires entities to recognize the tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. The standard is effective for interim and annual reporting periods beginning after December 15, 2017, although early adoption is permitted as of the beginning of an annual period (i.e., only in the first interim period)5.55%. The guidance requires application using a modified retrospective approach. The Partnership does not expect the adoption of this standard to have a material impact on our Condensed Consolidated Financial Statements and related disclosures.


As of March 31, 2019, we have right-of-use assets of $33 million recorded as Other Assets, $8 million of corresponding obligations recorded as Other Current Liabilities and $26 million of corresponding obligations recorded as Other Liabilities on the Partnership’s Condensed Consolidated Balance Sheet. All lease obligations outstanding during the three months ended March 31, 2019 were classified as operating leases, therefore all cash flows are reflected in Cash Flows from Operating Activities. During the three months ended March 31, 2019, rental costs associated with field equipment and buildings were $7 million and $2 million, respectively.

Under ASC 842, as of March 31, 2019, the Partnership has operating lease obligations expiring at various dates. The $17 million difference between undiscounted cash flows for operating leases and our $35 million of lease obligations is due to the impact of the applicable discount rate. Undiscounted cash flows for operating lease liabilities are as follows:

(5) Acquisition

Velocity Holdings, LLC Acquisition

On November 1, 2018, the Partnership acquired all of the equity interests in Velocity Holdings, LLC, now EOCS, which owns and operates a crude oil and condensate gathering system in the SCOOP and STACK plays of the Anadarko Basin, for approximately $444 million in cash, subject to certain customary working capital adjustments. The acquisition was accounted for as a business combination and was funded with borrowings under the commercial paper program. During the fourth quarter of 2018, the Partnership finalized the purchase price allocation as of November 1, 2018.

The following table presents the fair value of the identified assets acquired and liabilities assumed at the acquisition date:

Purchase price allocation:

Current Assets3
Property, plant and equipment124
Intangibles259

Less: Non-Controlling Interest at fair value28
Total identifiable net assets$444

The Partnership recognized intangible assets related to customer relationships. The acquired intangible assets will be amortized on a straight-line basis over the estimated customer contract life of approximately 15 years. Goodwill recognized from the acquisition primarily relates to greater operating leverage in the Anadarko Basin and is allocated to the gathering and processing segment. Included within the acquisition was 60% of a 26-mile pipeline system joint venture with a third party which owns and operates a refinery connected to the EOCS system. This joint venture’s financials have been consolidated within the Partnership’s financial statements resulting in $28 million in non-controlling interest. The Partnership incurred approximately $6 million of acquisition costs associated with this transaction, which were included in General and administrative expense in the Consolidated Statements of Income for the twelve months ended December 31, 2018. The Partnership determined not to include pro forma consolidated financial statements for the periods presented as the impact would not be material.

General Partner Interest and Incentive Distribution Rights

Enable GP owns a non-economic general partner interest in the Partnership and thus will not be entitled to distributions that the Partnership makes prior to the liquidation of the Partnership in respect of such general partner interest. Enable GP currently holds incentive distribution rights that entitle it to receive increasing percentages, up to a maximum of 50.0%, of the cash the Partnership distributes from operating surplus (as defined in the Partnership Agreement) in excess of $0.330625 per unit per

quarter. The maximum distribution of 50.0% does not include any distributions that Enable GP or its affiliates may receive on common units that they own.

Expiration of Subordination Period

The financial tests required for conversion of all subordinated units were met and the 207,855,430 outstanding subordinated units converted into common units on a one-for-one basis on August 30, 2017. The conversion of the subordinated units did not change the aggregate amount of outstanding units, and the conversion of the subordinated units did not impact the amount of cash available for distribution by the Partnership.

Series A Preferred Units

On February 18, 2016, the Partnership completed the private placement of 14,520,000 Series A Preferred Units representing limited partner interests in the Partnership for a cash purchase price of $25.00 per Series A Preferred Unit, resulting in proceeds of $362 million, net of issuance costs. The Partnership incurred approximately $1 million of expenses related to the offering, which is shown as an offset to the proceeds. In connection with the closing of the private placement, the Partnership redeemed approximately $363 million of notes scheduled to mature in 2017 payable to a wholly-owned subsidiary of CenterPoint Energy.

Pursuant to the Partnership Agreement, the Series A Preferred Units:
rank senior to the Partnership’s common units with respect to the payment of distributions and distribution of assets upon liquidation, dissolution and winding up;
have no stated maturity;
are not subject to any sinking fund; and
will remain outstanding indefinitely unless repurchased or redeemed by the Partnership or converted into its common units in connection with a change of control.

Holders of the Series A Preferred Units receive a quarterly cash distribution on a non-cumulative basis if and when declared by the General Partner, and subject to certain adjustments, equal to an annual rate of: 10% on the stated liquidation preference of $25.00 from the date of original issue to, but not including, the five year anniversary of the original issue date; and thereafter a percentage of the stated liquidation preference equal to the sum of the three-month LIBOR plus 8.5%.

At any time on or after five years after the original issue date, the Partnership may redeem the Series A Preferred Units, in whole or in part, from any source of funds legally available for such purpose, by paying $25.50 per unit plus an amount equal to all accumulated and unpaid distributions thereon to the date of redemption, whether or not declared. In addition, the Partnership (or a third-party with its prior written consent) may redeem the Series A Preferred Units following certain changes in the methodology employed by ratings agencies, changes of control or fundamental transactions as set forth in the Partnership Agreement. If, upon a change of control or certain fundamental transactions, the Partnership (or a third-party with its prior written consent) does not exercise this option, then the holders of the Series A Preferred Units have the option to convert the Series A Preferred Units into a number of common units per Series A Preferred Unit as set forth in the Partnership Agreement. The Series A Preferred Units are also required to be redeemed in certain circumstances if they are not eligible for trading on the New York Stock Exchange.

Holders of Series A Preferred Units have no voting rights except for limited voting rights with respect to potential amendments to the Partnership Agreement that have a material adverse effect on the existing terms of the Series A Preferred Units, the issuance by the Partnership of certain securities, approval of certain fundamental transactions and as required by law.

Upon the transfer of any Series A Preferred Unit to a non-affiliate of CenterPoint Energy, the Series A Preferred Units will automatically convert into a new series of preferred units (the Series B Preferred Units) on the later of the date of transfer and the second anniversary of the date of issue. The Series B Preferred Units will have the same terms as the Series A Preferred Units except that unpaid distributions on the Series B Preferred Units will accrue on a cumulative basis until paid.

On February 18, 2016, the Partnership entered into a registration rights agreement with CenterPoint Energy, pursuant to which, among other things, the Partnership gave CenterPoint Energy certain rights to require the Partnership to file and maintain a registration statement with respect to the resale of the Series A Preferred Units and any other series of preferred units or common units representing limited partner interests in the Partnership that are issuable upon conversion of the Series A Preferred Units.

ForDuring the ninethree months ended September 30, 2017,March 31, 2019 and March 31, 2018, the Partnership sold an aggregate of 18,500did not issue common units under the ATM Program, which generated proceedsProgram. As of approximately $303,000 (netMarch 31, 2019, $197 million of approximately $3,000 of commissions). The Partnership incurred approximately $345,000 of expenses associated with the filing of the registration statementscommon units remained available for issuance through the ATM Program. The proceeds were used for general partnership purposes.

2016 Equity Issuance

On November 29, 2016, the Partnership closed a public offering of 10,000,000 common units at a price to the public of $14.00 per common unit. In connection with the offering, the Partnership, the underwriters and an affiliate of ArcLight entered into an underwriting agreement that provided an option for the underwriters to purchase up to an additional 1,500,000 common units, with 75,719 common units to be sold by the Partnership and 1,424,281 to be sold by the affiliate of ArcLight. The underwriters exercised the option to purchase all of the additional common units, and the Partnership received proceeds (net of underwriting discounts, structuring fees and offering expenses) of $137 million from the offering.


(5) Assessing 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. During each of the three and nine months ended September 30, 2016, the Partnership recorded an $8 million impairment to the Service Star business line, which is included in Impairments on the Condensed Consolidated Statements of Income and impaired substantially all of the remaining net book value of the Service Star business line. The Service Star business line was a component of the gathering and processing segment that provided measurement and communication services to third parties and the impairment was primarily driven by the impact of planned technology changes affecting Service Star. The Partnership recorded no impairments to long-lived assets in the three and nine months ended September 30, 2017. Based upon review of forecasted undiscounted cash flows, none of the asset groups were at risk of failing step one of the impairment test. Commodity price declines, throughput declines, cost increases, regulatory or political environment changes, and other changes in market conditions could reduce forecast undiscounted cash flows.


(6)(8) Investment in Equity Method Affiliate

SESH is owned 50% by Spectra Energy Partners, LPEnbridge, 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, Spectra Energy Partners, LPEnbridge, 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 Spectra Energy Partners, LPEnbridge, 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.

(8)(10) Derivative Instruments and Hedging Activities
 
The Partnership is exposed to certain risks relating to its ongoing business operations. The primary risk managed using derivative instruments is commodity price risk. The Partnership is also exposed to credit risk in its business operations.
 
Commodity Price Risk
 
The Partnership has used forward physical contracts, commodity price swap contracts and commodity price option features to manage the Partnership’s commodity price risk exposures in the past. Commodity derivative instruments used by the Partnership are as follows:
NGL put options, NGL futures and swaps, and WTI crude oil futures, swaps and swaps for condensate salesswaptions are used to manage the Partnership’s NGL and condensate exposure associated with its processing agreements;
natural gas futures and swaps, are used to manage the Partnership’s natural gas exposure associated with its gathering, processing and transportation and storage assets; and
natural gas futures and swaps, natural gas options, natural gas swaptions and natural gas commodity purchases and sales are used to manage the Partnership’s natural gas exposure associated with its gathering, processing, transportation and storage and transportationassets, contracts and asset management activities.

Normal purchases and normal sales contracts are not recorded in Other Assets or Liabilities in the Condensed Consolidated Balance Sheets and earnings are recognized and recorded in the period in which physical delivery of the commodity occurs. Management applies normal purchases and normal sales treatment to: (i) commodity contracts for the purchase and sale of natural gas used in or produced by the Partnership’s operations and (ii) commodity contracts for the purchase and sale of NGLs produced by the Partnership’s gathering and processing business.
 
The Partnership recognizes its non-exchange traded derivative instruments as Other Assets or Liabilities in the Condensed Consolidated Balance Sheets at fair value with such amounts classified as current or long-term based on their anticipated settlement. Exchange traded transactions are settled on a net basis daily through margin accounts with a clearing broker and therefore, are recorded as Other Assets or Liabilities in the Condensed Consolidated Balance Sheets at fair value on a net basis in Other Current Assets in the Condensed Consolidated Balance Sheets.with such amounts classified as current or long-term based on their anticipated settlement.
 
As of September 30, 2017March 31, 2019 and December 31, 2016,2018, the Partnership had no derivative instruments that were designated as cash flow or fair value hedges for accounting purposes.

Credit Risk
 
The Partnership is exposed to certain credit risks relating to its ongoing business operations. Credit risk includes the risk that counterparties that owe the Partnership money or energy will breach their obligations. If the counterparties to these arrangements fail to perform, the Partnership may seek or be forced to enter into alternative arrangements. In that event, the Partnership’s financial results could be adversely affected, and the Partnership could incur losses.
 

Derivatives Not Designated Asas Hedging Instruments
 
Derivative instruments not designated as hedging instruments for accounting purposes are utilized in the Partnership’s asset management activities. For derivative instruments not designated as hedging instruments, the gain or loss on the derivative is recognized currently in earnings.


Quantitative Disclosures Related to Derivative Instruments
 
The majority of natural gas physical purchases and sales not designated as hedges for accounting purposes are priced based on a monthly or daily index, and the fair value is subject to little or no market price risk. Natural gas physical sales volumes exceed natural gas physical purchase volumes due to the marketing of natural gas volumes purchased via the Partnership’s processing contracts, which are not derivative instruments.

As of September 30, 2017March 31, 2019 and December 31, 2016,2018, the Partnership had the following derivative instruments that were not designated as hedging instruments for accounting purposes:

Credit-Risk Related Contingent Features in Derivative Instruments
 
Based uponIn the Partnership’s senior unsecured debt rating withevent Moody’s Investors Services or Standard & Poor’s Ratings Services 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, 2017,March 31, 2019, under these obligations, $1 million ofthe Partnership has posted no cash collateral has been postedrelated to NGL swaps and $1 million ofcrude swaps and swaptions and no additional collateral may be required to be posted by the Partnership.Partnership in the event of a credit ratings downgrade to a below investment grade rating.


(9)(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. Hierarchical levels, as defined below and directly related to the amount of subjectivity associated with the inputs to fair valuations of these assets and liabilities are as follows:
 
Level 1: Inputs are unadjusted quoted prices in active markets for identical assets or liabilities at the measurement date. Instruments classified as Level 1 include natural gas futures, swaps and options transactions for contracts traded on either the NYMEX or the ICE and settled through either a NYMEX or ICE clearing broker.
 
Level 2: Inputs, other than quoted prices included in Level 1, are observable for the asset or liability, either directly or indirectly. Level 2 inputs include quoted prices for similar instruments in active markets, and inputs other than quoted prices

that are observable for the asset or liability. Fair value assets and liabilities that are generally included in this category are derivatives with fair values based on inputs from actively quoted markets. Instruments classified as Level 2 generally include over-the-counter NYMEX natural gas swaps, natural gas swaptions, natural gas basis swaps and natural gas purchase and sales transactions in markets such that the pricing is closely related to the NYMEX or the ICE pricing, and over-the-counter WTI crude oil swaps and swaptions for condensate sales.
 
Level 3: Inputs are unobservable for the asset or liability, and include situations where there is little, if any, market activity for the asset or liability. Unobservable inputs reflect the Partnership’s judgments about the assumptions market participants would use in pricing the asset or liability since limited market data exists. The Partnership develops these inputs based on the best information available, including the Partnership’s own data.
 
The Partnership utilizes the market approach in determining the fair value of its derivative positions by using either NYMEX, ICE or WTI published market prices, independent broker pricing data or broker/dealer valuations. The valuations of derivatives with pricing based on NYMEX or ICE published market prices may be considered Level 1 if they are settled through a NYMEX or ICE clearing broker account with daily margining. Over-the-counter derivatives with NYMEX, ICE or WTI based prices are considered Level 2 due to the impact of counterparty credit risk. Valuations based on independent broker pricing or broker/dealer valuations may be classified as Level 2 only to the extent they may be validated by an additional source of independent market data for an identical or closely related active market. Certain derivatives with option features may be classified as Level 2 if valued using an industry standard Black-Scholes option pricing model that contain observable inputs in the marketplace throughout the term of the derivative instrument. In certain less liquid markets or for longer-term contracts, forward prices are not as readily available. In these circumstances, contracts are valued using internally developed methodologies that consider historical relationships among various quoted prices in active markets that result in management’s best estimate of fair value. These contracts are classified as Level 3. As of March 31, 2019, there were no contracts classified as Level 3.
 

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 periodthree months ended September 30, 2017,March 31, 2019, there were no transfers between levels.
 
The impact to the fair value of derivatives due to credit risk is calculated using the probability of default based on Standard & Poor’s Ratings Services and/or internally generated ratings. The fair value of derivative assets is adjusted for credit risk. The fair value of derivative liabilities is adjusted for credit risk only if the impact is deemed material.

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 following table summarizes the fair value and carrying amount of the Partnership’s financial instruments as of September 30, 2017March 31, 2019 and December 31, 2016.2018.

Borrowing capacity is effectively reduced by our borrowings outstanding under the commercial paper program. $796 million and $649 million of commercial paper was outstanding as of March 31, 2019 and December 31, 2018, respectively.

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, 2017,March 31, 2019, no material fair value adjustments or fair value measurements were required for these non-financial assets or liabilities.

Contracts with Master Netting Arrangements
 
Fair value amounts recognized for forward, interest rate swap, option and other conditional or exchange contracts executed with the same counterparty under a master netting arrangement may be offset. The reporting entity’s choice to offset or not must be applied consistently. A master netting arrangement exists if the reporting entity has multiple contracts, whether for the same type of conditional or exchange contract or for different types of contracts, with a single counterparty that are subject to a contractual agreement that provides for the net settlement of all contracts through a single payment in a single currency in the event of default on or termination of any one contract. Offsetting the fair values recognized for forward, interest rate swap, option and other conditional or exchange contracts outstanding with a single counterparty results in the net fair value of the transactions being reported as an asset or a liability in the Condensed Consolidated Balance Sheets. The Partnership has presented the fair values of its derivative contracts under master netting agreements using a net fair value presentation.
 

The following tables summarize the Partnership’s assets and liabilities that are measured at fair value on a recurring basis as of September 30, 2017March 31, 2019 and December 31, 2016:2018:

______________________
(1)The Partnership uses the market approach to fair value its gas imbalance assets and liabilities at individual, or where appropriate an average of, current market indices applicable to the Partnership’s operations, not to exceed net realizable value. Gas imbalances held by EOIT are valued using an average of the Inside FERC Gas Market Report for Panhandle Eastern Pipe Line Co. (Texas, Oklahoma Mainline), ONEOK (Oklahoma) and ANR Pipeline (Oklahoma) indices. There were no netting adjustments as of September 30, 2017March 31, 2019 and December 31, 2016.2018.
(2)Gas imbalance assets exclude fuel reserves for under retained fuel due from shippers of $2$8 million and zero$11 million at September 30, 2017March 31, 2019 and December 31, 2016,2018, respectively, which fuel reserves are based on the value of natural gas at the time the imbalance was created, and which are not subject to revaluation at fair market value.
(3)Gas imbalance liabilities exclude fuel reserves for over retained fuel due to shippers of zero$9 million and $5 million at September 30, 2017March 31, 2019 and December 31, 2016,2018, respectively, which fuel reserves are based on the value of natural gas at the time the imbalance was created, and which are not subject to revaluation at fair market value.

Quantitative Information on Level 3 Fair Value Measurements

The Partnership utilizes the market approach to measure the fair value of our commodity contracts. The significant unobservable inputs used in this approach to fair value are longer dated price quotes. Our sensitivity to these longer dated forward curve prices are presented in the table below. Significant changes in any of those inputs in isolation would result in significantly different fair value measurements, depending on our short or long position in contracts.

(12)(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 400 MMcf/d of deliveries to the Godley Plant in Johnson County, Texas. As of March 31, 2019, the Partnership estimates the remaining associated 10-year minimum volume commitment fee to be $209 million.

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 LNG facility to be served by the Gulf Run Pipeline project. Subject to approval of the project by the FERC, the Partnership will be required to construct a large-diameter pipeline from northern Louisiana to Gulf Coast markets. In addition, the Partnership may transfer existing EGT transportation infrastructure to the Gulf Run Pipeline. Under the precedent agreement, the Partnership estimates the cost to complete the Gulf Run Pipeline project would be as much as $550 million and the project is backed by a 20-year firm transportation service. 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 2022.

(14)(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 20162018 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.

(15) Subsequent Event

On October 4, 2017, the Partnership acquired all of the equity interests in Align Midstream, LLC, a midstream company with natural gas gathering and processing facilities in the Cotton Valley and Haynesville plays of the Ark-La-Tex Basin, for approximately $300 million, subject to certain post-closing adjustments. The acquisition will be treated as a business combination and was funded with borrowings under the Revolving Credit Facility. Due to the timing of the acquisition, the Partnership has not yet completed its initial accounting analysis. As a result, the Partnership is unable to provide amounts recognized as of the acquisition date for major classes of assets and liabilities acquired and resulting from the transaction, including any intangible assets or goodwill.


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, 2016,2018, 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. 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.

Overview

Enable Midstream Partners, LP is a Delaware limited partnership formed in May 2013 by CenterPoint Energy, OGE Energy and ArcLight to own, operate and develop midstream energy infrastructure assets strategically located to serve our customers. We completed our IPOinitial public offering in April 2014, and 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 Bakken Shale formation of theAnadarko and Williston Basin.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, aan 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.Report, as well as the recent developments discussed herein. 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, and growing through accretive acquisitions, maintaining strong customer relationships to attract new volumes and disciplined development.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 the development of 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.

Typically, we do not announce a transaction until after we have executed a definitive agreement. However, in certain cases in order to protect our business interests or for other reasons, we may defer public announcement of a transaction until closing or a later date. Past experience has demonstrated that the pace of discussions and negotiations regarding potential transactions is unpredictable and can advance or terminate in a short period of time.


Recent Developments

AcquisitionRegulatory Update

The regulation of Align Midstreammidstream energy infrastructure assets has a significant impact on our business. For example, our interstate natural gas transportation and storage assets are subject to regulation by FERC under the Natural Gas Act (NGA). In March 2018, FERC announced a Revised Policy Statement on Treatment of Income Taxes stating that it would no longer allow pipelines organized as a master limited partnership to recover an income tax allowance in their cost-of-service rates. In July 2018, FERC issued new regulations which required all FERC-regulated natural gas pipelines to make a one-time Form No. 501-G filing providing certain financial information and to select one of four options: (i) file a limited NGA Section 4 filing reducing its rates only as required in relation to the Tax Cuts and Jobs Act of 2017 and the Revised Policy Statement, (ii) commit to filing a general NGA Section 4 rate case in the near future, (iii) file a statement explaining why an adjustment to rates is not needed, or (iv) take

no other action. In October 2018, EGT filed its Form No. 501-G and filed a statement that it intended to take no other action. On March 8, 2019, FERC terminated EGT’s 501-G proceeding and required no other action.

MRT did not file a FERC Form No. 501-G because MRT had filed a general NGA Section 4 rate case in June 2018. The rate case proposed, among other things, a general system-wide increase in the maximum tariff rates for all firm and interruptible services offered by MRT, a change in the boundary between the Field and Market zones, a requirement for daily balancing, changes to the Small Customer service rate schedule and an income tax allowance in its cost-of-service rates. In July 2018, FERC issued an order accepting MRT’s proposed rate increases subject to refund upon a final determination of MRT’s rates and ordering MRT to refile its rate case to reflect, the elimination of an income tax allowance in its cost-of-service rates. On August 30, 2018, MRT submitted a supplemental filing to comply with FERC’s order. MRT has appealed FERC’s order to eliminate the income tax allowance in its cost-of-service rates, but we believe that the ordered elimination will have a de minimis impact on MRT’s rates. On February 19, 2019, FERC set MRT’s refiled rate case for hearing set to begin in November 2019.

On October 4, 2017,April 12, 2019, FERC accepted EGR and EGT into the Partnership completed the acquisition of Align Midstream, LLC, a midstream companypre-filing process in connection with their prospective applications for certificate to construct, operate and maintain natural gas gatheringpipeline facilities. Using the pre-filing procedures should enable more efficient and processing facilitiesexpeditious actions by FERC on EGR’s and EGT’s certificate applications allowing these entities, in advance of filing certificate applications with FERC, to engage stakeholders in the Cotton Valleyidentification and Haynesville playsresolution of concerns and to engage a consultant to work at FERC’s direction to perform an environmental impact assessment.

In addition to the regulation of our interstate natural gas transportation and storage assets by FERC, our midstream energy infrastructure assets are subject to regulation by various federal and state agencies, including DOT’s Pipeline and Hazardous Materials Safety Administration. For an additional discussion of the Ark-La-Tex Basin, for approximately $300 million, subject to certain customary post-closing adjustments. The acquisition includes approximately 190 milesimpact of natural gas gathering pipelines across Rusk, Panolaregulation on our business, see Item 1, Rate and Shelby countiesOther Regulation in Texas and DeSoto Parish in Louisiana and a cryogenic natural gas processing plant in Panola County, Texas, with a capacity of 100 MMcf/d. These assets are underpinned with long-term, fee-based contracts, including approximately 100,000 gross acres of dedication from producer customers.

ATM ProgramLiquidity Update

Term Loan Agreement

On May 12, 2017,January 29, 2019, the Partnership entered into a term loan facility, providing for an ATM Equity Offering Sales Agreement in connection with an at-the-market program (the “ATM Program”). Pursuant to the ATM Program, 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 Partnership has no obligation to sell any common units under the ATM Program and the Partnership may suspend sales under the ATM Program at any time.unsecured three-year $1 billion term loan agreement. For the nine months ended September 30, 2017, the Partnership sold an aggregate of 18,500 common units under the ATM Program, which generated proceeds of approximately $303,000 (net of approximately $3,000 of commissions). The Partnership incurred approximately $345,000 of expenses associated with the filingmore information, please see Note 9 of the registration statements for the ATM Program. The proceeds were used for general partnership purposes.

Issuance of Senior Notes

On March 9, 2017, the Partnership completed the public offering of $700 million 4.400% Senior Notes due 2027 (2027 Notes). The Partnership received net proceeds of approximately $691 million. The proceeds were used for general partnership purposes, including to repay amounts outstanding under the Revolving Credit Facility.

Commercial and Construction Update

Project Wildcat rich gas takeaway solution

The Partnership has entered into an agreement to deliver approximately 400 MMcf/d of rich natural gas from the Anadarko Basin to north Texas, providing a new market outlet for growing Anadarko Basin production. Project Wildcat is expected to provide access to the Texas intrastate natural gas markets, including the Tolar Hub, by contracting with an affiliate of Energy Transfer Partners, LP for 400 MMcf/d of firm processing capacity at the Godley Plant in Johnson County, Texas. The project is expected to be in service by the end of the second quarter of 2018. Even with the 400 MMcf/d of processing capacity provided by this project, the Partnership anticipates that there will be a need to resume construction of the previously announced Wildhorse Plant, though likely not before 2019.

EGT Expansion Project

In March 2017, EGT conducted a non-binding open season to solicit commitments for the Cana and STACK Expansion (CaSE) project, a system expansion providing firm transportation service for growing Anadarko Basin production. The project’s foundation shipper, Newfield Exploration Company, has entered into a 205,000 Dth/d firm natural gas transportation agreement with EGT. The 10-year contract is expected to start at an initial capacity of 45,000 Dth/d in early 2018 and grow to the full contracted capacity by the fourth quarter of 2018.

CenterPoint Strategic Review

As previously disclosed, CenterPoint Energy has announced that it is evaluating strategic alternatives for its investment in Enable. CenterPoint Energy has disclosed that the alternatives may include a sale of all or a portion of the interests that it owns in Enable and Enable GP, that if the sale option is not viable it intends to reduce its ownership in Enable over time through a sale of the Enable common units it holds in the public equity markets subject to market conditions, and that there can be no assurances that these evaluations will result in any specific action.Condensed Consolidated Financial Statements.

changes in the fair value of natural gas, condensate and NGL derivatives decreased $11 million, and
revenues from NGL sales resultingdecreased $6 million primarily due to a decrease in the average realized sales price from lower average market prices for all NGL products other than ethane and higher average NGL prices andvolumes subject to fee deductions for NGLs sold under certain third-party processing arrangements, partially offset by higher processed volumes and higher recoveries of ethane in the Anadarko Basin, a $14 million increase in and Ark-La-Tex Basins, which were sold at higher average ethane prices.
Service Revenues:
natural gas gathering revenues increased $25 million due to higher fees and gathered volumes in the Anadarko Basin,
crude oil, condensate and Ark-La-Tex Basinsproduced water gathering revenues increased $7 million primarily due to an increase related to the November 2018 acquisition of EOCS, and a $9 million increase in
processing service revenues increased $3 million resulting from higher processed volumes primarily under fixed processing arrangements, partially offset by lower consideration received from percent-of-proceeds, percent-of-liquids and keep-whole processing arrangements due to a percent-of-proceeds contract that was converted to a fee-based contract during the fourth quarter of 2016. These increases

were partially offset by a $9 million decrease in revenues from changes in the fair value of condensate and NGL derivatives, a $5 million decrease in revenues from sales of natural gas and a $1 million decrease in revenues due to a wind-down of third-party measurement and communication services in 2017.average realized price.

This increase was partially offset by:
system management activities decreased $3 million,

Our transportation and storage segment operation and maintenance and general and administrative expenses decreased $1 million. TheThis decrease was primarily due to a $2 million decrease in payroll-related costs, partially offsetdriven by a $1 million increase in various other operatingdecrease due to increased capitalized overhead costs.

Our transportation and storage segment depreciation and amortization increaseddecreased $3 million due to additional assets placed in service.

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

Nine months ended September 30, 2017 compared to nine months ended September 30, 2016. Our transportation and storage segment reported operating income of $158 million in the nine months ended September 30, 2017 compared to operating income of $157 million in the nine months ended September 30, 2016. The difference of $1 million in operating income between periods was primarily due to a $3 million increase in gross margin and a $5 million decrease in operation and maintenance and general and administrative expenses, partially offset by a $6 million increase in depreciation and amortization and a $1 million increase in taxes other than income forfrom the nine months ended September 30, 2017.

Our transportation and storage segment revenues increased $78 million. The increase was primarily due to a $47 million increase in revenues from changes in the fair valueimplementation of new intrastate natural gas derivatives, a $45 million increase in revenuespipeline rates from higher natural gas sales associated with higher sales volumes and higher average sales prices, a $7 million increase in revenues from NGL sales due to an increase in prices, a $6 million increase in revenues from off-system transportation and a $2 million increase in revenues from firm transportation. These increases were partially offset by a $15 million decrease in firm transportation services between Carthage, Texas, and Perryville, Louisiana, a decrease of $8 million due to lower realized gains on natural gas derivatives and a $2 million decrease in revenues from transportation services for LDCs.


Our transportation and storage segment gross margin increased $3 million. The increase was primarily due to a $47 million increase in gross margin from changes in the fair value of natural gas derivatives, a $6 million increase in off-system transportation margins, a $4 million increase in NGL sales due to an increase in prices and a $2 million increase in firm transportation. These increases were partially offset by a $32 million decrease in system management activities, a decrease of $15 million in firm transportation services between Carthage, Texas, and Perryville, Louisiana, a decrease of $8 million due to realized gains on natural gas derivatives as compared to realized losses in 2016 and a $2 million decrease in margins from transportation services for LDCs.

Our transportation and storage segment operation and maintenance and general and administrative expenses decreased $5 million. The decrease was primarily due to a $4 million decrease in materials and supplies and contract services and a $2 million decrease in loss on sale of assets.

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. We expect that our liquidity and capital resource needs will be met by cash on hand, operating cash flow, proceeds from commercial paper issuances, borrowings under our revolving credit facility, borrowings under our term loan, debt issuances and the issuance of equity. However, issuances of equity or debt in the capital markets and additional credit facilities may not be available to us on acceptable terms. Access to funds obtained through the equity or debt capital markets, particularly in the energy sector, has been constrained by a variety of market factors that have hindered the ability of energy companies to raise new capital or obtain financing at acceptable terms. Factors that contribute to our ability to raise capital through these channels depend on our financial condition, credit ratings and market conditions. 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.
 
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, and the level and timing of spending for maintenance and expansion activity.activity, and the timing of debt maturities. As of September 30, 2017,March 31, 2019, we had a working capital deficit of $385 million.$1.5 billion. The deficit is primarily due to the classification of $756 million of 2019 Notes and the 2015 Term Loan AgreementEOIT Senior Notes as Current portion of long-term debt as of September 30, 2017.March 31, 2019 as well as $796 million of commercial paper

outstanding as of March 31, 2019. We utilize our revolving credit facilitycommercial paper program and Revolving Credit Facility to manage the timing of cash flows and fund short-term working capital deficits.

Sources of Liquidity

As of September 30, 2017,March 31, 2019, our sources of liquidity included:
cash on hand;
cash generated from operations;
proceeds from commercial paper issuances;
borrowings under our 2019 Term Loan Agreement
borrowings under our Revolving Credit Facility; and
capital raised through debt and equity markets.


Distribution Reinvestment PlanATM Program

In June 2016,On May 12, 2017, the Partnership implemented a Distribution Reinvestment Plan (DRIP),entered into an ATM Equity Offering Sales Agreement, pursuant to which beginning with the quarterly distribution forPartnership 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 quarter ended September 30, 2016, offers ownerstime of our common and subordinated units the abilityofferings. The Partnership has no obligation to purchase additionalsell any common units by reinvesting all or a portion ofunder the cash distributions paid to them on their common or subordinated units. TheATM Program and the Partnership will havemay suspend sales under the sole discretion to determine whetherATM Program at any time. During the three months ended March 31, 2019 and 2018, the Partnership did not issue common units purchased under the DRIP will come from our newly issuedATM Program. As of March 31, 2019, $197 million of common units or from common units purchased onremained available for issuance through the open market. The purchase price for newly issued common units will be the average of the high and low trading prices of the common units on the New York Stock Exchange-Composite Transactions for the five trading days immediately preceding the investment date. The purchase price for common units purchased on the open market will be the weighted average price of all common units purchased for the DRIP for the respective investment date. We can set a discount ranging from 0% to 5% for common units purchased pursuant to the DRIP. The discount is currently set at 0%. Participation in the DRIP is voluntary, and once enrolled, our unitholders may terminate participation at any time.ATM Program.

Capital Requirements
The midstream business is capital intensive and can require significant investment to maintain and upgrade existing operations, connect new wells to the system, organically grow into new areas and comply with environmental and safety regulations. Going forward, our capital requirements will consist of the following:
maintenance capital expenditures, which are cash expenditures (including expenditures for the construction or development of new capital assets or the replacement, improvement or expansion of existing capital assets) made to maintain, over the long-term, our operating capacity or operating income; and
expansion capital expenditures, which are cash expenditures incurred for acquisitions or capital improvements that we expect will increase our operating income or operating capacity over the long term.
Our future expansion capital expenditures may vary significantly from period to period based on commodity prices and the investment opportunities available to us. We expect to fund future capital expenditures from cash flow generated from our operations, borrowings under our Revolving Credit Facility, new debt offerings or the issuance of additional partnership units. Issuances of equity or debt in the capital markets may not, however, be available to us on acceptable terms.
Distributions
 
On October 31, 2017,April 29, 2019, the boardBoard of directors of Enable GPDirectors declared a quarterly cash distribution of $0.318 per common unit on all of the Partnership’s outstanding common units for the periodthree months ended September 30, 2017.March 31, 2019. The distributions will be paid November 21, 2017May 29, 2019 to unitholders of record as of the close of business on November 14, 2017.May 21, 2019. Additionally, the boardBoard of directors of Enable GPDirectors declared a quarterly cash distribution of $0.625 on the Partnership’s outstanding Series A Preferred Units. The distributions will be paid November 14, 2017May 15, 2019 to unitholders of record as of the close of business on October 31, 2017.

Expiration of Subordination Period

The financial tests required for conversion of all subordinated units were met and the 207,855,430 outstanding subordinated units converted into common units on a one-for-one basis on August 30, 2017. The conversion of the subordinated units did not change the aggregate amount of outstanding units, and the conversion of the subordinated units did not impact the amount of cash available for distribution by the Partnership.April 29, 2019.

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 counterparties that owe us money or energy commodities will breach their obligations. If the counterparties to these arrangements fail to perform, we may be forced to enter into alternative arrangements. In that event, our financial results could be adversely affected, and we could incur losses. We examine the creditworthiness of third partythird-party customers to whom we extend credit and manage our exposure to credit risk through credit analysis, credit approval, credit limits and monitoring procedures, and for certain transactions, we may request letters of credit, prepayments or guarantees.



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 on Form 10-K for the year ended December 31, 2016.Report. The accounting policies and estimates used in preparing our interim Condensed Consolidated Financial Statements for the three months ended September 30, 2017March 31, 2019 are the same as those described in our Annual Report on Form 10-K for the year ended December 31, 2016.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. The Partnership utilizes derivatives and forward commodity sales to mitigate the effects of price changes. We do not enter into risk management contracts for speculative purposes. For further information regarding our derivatives, see Note 8.10 of the Notes to the Unaudited Condensed Consolidated Financial Statements.
 
Based on our forecasted volumes, prices and contractual arrangements, we estimate approximately 16%13% of our total gross margin for the twelve months endingended December 31, 20172019 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, 2019, we have entered into additional derivative contracts to further manage our exposure to commodity price risk for the nine months ending December 31, 2019.


Commodity price risk is estimated as the potential loss in value resulting from a hypothetical 10% decline in prices over the next sixnine months. Based on a sensitivity analysis, a 10% decrease in prices from forecasted levels would decrease net income by approximately $3$11 million for natural gas and ethane and $3$8 million for NGLs excluding ethane(other than ethane) and condensate, excluding the impact of hedges, for the remaining threenine months ending December 31, 2017.2019.

Interest Rate Risk
 
Our current interest rate risk exposure is related primarily to our debt portfolio. Our debt portfolio is substantially comprised ofincludes senior notes with a fixed rate debt,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 Revolving Credit Facility, 20152019 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. Based upon the $523$996 million outstanding borrowings under the 2015commercial paper and 2019 Term Loan Agreement and Revolving Credit Facility as of September 30, 2017,March 31, 2019, and holding all other variables constant, a 100 basis-point, or 1%, increase in interest rates would increase our annual interest expense by approximately $5$10 million.


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 Securities Exchange Act of 1934, as amended (the “Exchange Act”))Act) as of September 30, 2017.March 31, 2019. Based on such evaluation, our management has concluded that, as of September 30, 2017,March 31, 2019, 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 Control Over Financial Reporting

During the three months ended September 30, 2017, the Partnership completed the implementation of natural gas and natural gas liquid marketing and risk management systems. The systems were implemented by the Partnership to improve standardization and not in response to any deficiency in internal control over financial reporting. Management believes the implementation of the systems and related changes to internal controls will enhance the Partnership's internal controls over financial reporting. Management believes the necessary steps have been taken to monitor and maintain appropriate internal control over financial reporting during this period of change and will continue to evaluate the operating effectiveness of related key controls during subsequent periods.

There were no other changes in our internal controls over financial reporting during the quarter ended September 30, 2017,March 31, 2019, that have materially affected, or that are reasonably likely to materially affect, our internal control over financial reporting.
