Item 1. Business

Overview

PART I

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 IPO 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 gathering and processing 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, a pipeline extending from Louisiana to Alabama.

As of December 31, 2018 , our portfolio of midstream energy infrastructure assets primarily included:

• 

• 

• 

• 

• 

approximately 13,900 miles of natural gas, crude oil, condensate and produced water gathering pipelines;

15 major processing plants with 2.6 Bcf/d of processing capacity;

approximately 7,800 miles of interstate pipelines (including SESH);

approximately 2,300 miles of intrastate pipelines; and

eight natural gas storage facilities with 84.5 Bcf of storage capacity.

Our website address is www.enablemidstream.com. Documents and information on our website are not incorporated by reference in this report. Our annual
reports  on  Form  10-K,  quarterly  reports  on  Form  10-Q,  current  reports  on  Form  8-K  and  amendments  to  those  reports  filed  with  or  furnished  to  the  SEC  are
available, free of charge, on our website as soon as reasonably practicable after we electronically file or furnish such materials.

Our Business Strategies

Our primary business objective is to increase the cash available for distribution to our unitholders over time while maintaining our financial flexibility. We

strive to meet this objective through the following strategies:

•

Capitalize  on  Organic  Growth  Opportunities  Associated  with  Our  Strategically  Located  Assets:  We  own  and  operate  assets  servicing  four  major
producing basins in the United States, including some of the most productive shale plays in these basins. We intend to grow our business by utilizing a
disciplined  approach  emphasizing  capital  efficiency  when  developing  new  midstream  energy  infrastructure  projects  to  support  new  and  existing
customers in these areas.

• Maintain Strong Customer Relationships to Attract New Volumes and Expand Beyond Our Existing Asset Footprint and Business Lines: Management
believes that we have built a strong and loyal customer base through exemplary customer service and reliable project execution. We have invested in
organic growth projects in support of our existing and new customers. We work to maintain and build relationships with key producers and suppliers in
an effort to attract new volumes and expansion opportunities.

•

Continue  to  Minimize  Direct  Commodity  Price  Exposure  Through  Fee-Based  Contracts:  We  continually  seek  ways  to  minimize  our  exposure  to
commodity price risk. Management believes that focusing on fee-based revenues reduces

5

 
 
 
 
Table of Contents

our  direct  commodity  price  exposure.  We  intend  to  maintain  our  focus  on  increasing  the  percentage  of  long-term,  fee-based  contracts  with  our
customers.

•

Grow Through Accretive Acquisitions: We continually evaluate potential acquisitions of complementary assets with the potential for attractive returns
in new and existing operating areas and midstream business lines. We will continue to analyze acquisition opportunities using disciplined financial and
operating practices, including evaluating and managing risks to cash available for distribution.

Our Sponsors

CenterPoint Energy and OGE Energy each own a significant interest in us. As of December 31, 2018 , CenterPoint Energy owned 54.0% of our common
units and  100%  of  our  Series  A  Preferred  Units,  and  OGE  Energy  owned  25.6% of  our  common  units.  In  addition,  our  sponsors  own  Enable  GP,  our  general
partner. As of December 31, 2018 , CenterPoint Energy owned a 50% management interest and a 40% economic interest in our general partner, and OGE Energy
owned a 50% management interest and a 60% economic interest in our general partner. Enable GP owns the non-economic general partner interest in us and all of
our incentive distribution rights.

CenterPoint Energy (NYSE: CNP) is a public utility holding company whose operating subsidiaries own and operate electric transmission and distribution
facilities, own and operate natural gas distribution facilities, and supply natural gas to commercial, industrial and utility customers. I n the first quarter of 2016,
CenterPoint Energy announced that it was evaluating strategic alternatives for its investment in Enable. In the first quarter of 2018, CenterPoint Energy disclosed
that it had decided not to pursue a sale or spin-off qualifying under Section 355 of the U.S. Internal Revenue Code at that time and that, while a transaction for all
of its interests in the Partnership was not viable at that time, it may pursue such a transaction if it becomes viable in the future. CenterPoint Energy also disclosed
that  it  may  reduce  its  investment  in  the  Partnership  through  a  sale  of  all  or  a  portion  of  the  Partnership  common  units  it  owns  in  the  public  equity  markets  or
otherwise, subject to certain limitations.

OGE Energy (NYSE: OGE) is an energy services provider offering physical delivery and related services for electricity.

Our sponsors are customers of our transportation and storage business. For the year ended December 31, 2018 , approximately 1% of our gross margin was
derived from transportation and storage contracts with an electric utility owned by OGE Energy. For the year ended December 31, 2018 , approximately 7% of our
total gross margin was derived from transportation and storage contracts servicing LDCs owned by CenterPoint Energy.

In addition, our sponsors have entered into a number of agreements affecting us. For a more detailed description of our relationship and agreements with
CenterPoint Energy and OGE Energy, please read Item 13. “Certain Relationships and Related Transactions, and Director Independence.” Although management
believes our relationships with CenterPoint Energy and OGE Energy are positive attributes, there can be no assurance that we will benefit from these relationships
or that these relationships will continue.

Our Assets and Operations  

Our assets and operations are organized into two reportable segments: (i) gathering and processing and (ii) transportation and storage.

We report natural gas gathered, processed and transported by energy content stated in millions or trillions of British thermal units (“MMBtu” or “TBtu”). We
report natural gas processing, transportation, and storage capacity by volume stated in millions or billions of cubic feet (“MMcf” or “Bcf”), and we also report
processing inlet volumes in millions of cubic feet. An MMcf of pipeline quality natural gas generally has an energy content of 1,000 MMbtu. We report crude oil,
condensate and product water capacities, crude oil, condensate, and produced water gathered, NGLs production capacity, and NGLs produced and sold, by volume
stated in barrels or thousands of barrels (“Bbl” or “Mbbl”).

Gathering and Processing

We  own  and  operate  substantial  natural  gas  gathering  and  processing  and  crude  oil,  condensate  and  produced  water  gathering  assets  in  five  states.  Our
gathering and processing operations consist primarily of natural gas gathering and processing assets serving the Anadarko, Arkoma and Ark-La-Tex Basins, crude
oil  and  condensate  gathering  assets  serving  the  Anadarko  Basin,  and  crude  oil  and  produced  water  assets  serving  the  Williston  Basin.  We  provide  a  variety  of
services to the active producers in

6

 
 
Table of Contents

our operating areas, including gathering, compressing, treating, and processing natural gas, fractionating NGLs, and gathering crude oil, condensate and produced
water. We serve shale and other unconventional plays in the basins in which we operate.

Natural Gas

• Anadarko Basin (Oklahoma, Texas Panhandle). We have natural gas gathering and processing operations in those portions of the Anadarko Basin located

natural  gas  produced  from  the  SCOOP,  STACK,  Granite  Wash,  Cleveland,  Marmaton,  Tonkawa,  Cana  Woodford  and  Mississippi  Lime  plays.  The
current focus of our Anadarko Basin gathering and processing operations is primarily on rich gas production.

• Arkoma  Basin  (Oklahoma,  Arkansas).  In  the  Arkoma  Basin,  our  operations  primarily  serve  the  Woodford  Shale  play  located  in  Oklahoma  and  the
Fayetteville  Shale  play  located  in  Arkansas.  Our  Arkoma  Basin  gathering  and  processing  operations  serve  both  rich  and  lean  gas  production.  As  of
December 31, 2018 , we served more than 80 producers in the Arkoma Basin.

• Ark-La-Tex  Basin  (Arkansas,  Louisiana  and  Texas).  We  have  gathering  and  processing  operations  in  the  Ark-La-Tex  Basin  located  in  Arkansas,
Louisiana and Texas. Our Ark-La-Tex gathering and processing operations primarily serve the Haynesville, Cotton Valley and the lower Bossier plays .
As of December 31, 2018 , we served over 100 producers in the Ark-La-Tex Basin where our gathering and processing operations provide service for
both rich and lean gas production.

In addition to the processing plants listed above, the Partnership is a party to a 10-year gathering and processing agreement, which became effective on July 1, 2018,
and provides for 400 MMcf/d of deliveries to Energy Transfer, LP’s Godley Plant in Johnson County, Texas.

(2) Excludes condensate.
(3) Average daily inlet volumes and inlet capacity includes 21 MMcf/d and 25 MMcf/d, respectively, related to a separate cryogenic unit.
(4) A processing plant has been in operation on the Waskom plant site since 1940. The Waskom plant was upgraded to cryogenic in 1995.

The natural gas processing assets in the Anadarko Basin include 11 processing plants, 10 of which are interconnected through our super-header system. The
super-header system is configured to facilitate the flow of natural gas across our operating areas in western Oklahoma and the Texas Panhandle to the Bradley II,
Bradley, McClure, Wheeler, South Canadian, Clinton, Canute, Cox City, Thomas and Calumet processing plants. The super-header system allows us to optimize
the utilization of the connected processing plants and additional third party contracted capacity at Energy Transfer, LP’s Godley plant. Similarly, the natural gas
processing assets in the Ark-La-Tex Basin include three processing plants, of which Waskom and Panola are interconnected to optimize the utilization of these
processing plants.

Natural gas that is gathered, and when applicable, processed, is typically redelivered to our customers at interconnections with transportation pipelines. Our
gathering lines interconnect with both our interstate and intrastate pipelines, as well as other interstate and intrastate pipelines, including the Acadian, ANR, ETC
Tiger,  Gulf  South,  NGPL,  Northern  Natural,  Panhandle  Eastern,  Regency,  Southern  Natural  Gas,  Tennessee  Gas,  Oklahoma  Gas  Transmission  and  Entergy
Transfer Katy pipelines. These connections provide producers with access to a variety of natural gas markets.

Natural  gas  is  comprised  primarily  of  methane,  but  at  the  wellhead  natural  gas  may  contain  varying  amounts  of  NGLs  which  may  be  separated  at  our
processing plants from the wellhead natural gas. We typically purchase the NGLs produced at our processing plants, and most of the NGLs are delivered into third-
party pipelines and transported to Conway, Kansas, or Mont Belvieu, Texas, where the NGLs are exchanged for fractionated NGLs that are sold under contract or
on  the  spot  market.  At  our  Cox  City,  Calumet  and  Wetumka  plants,  we  operate  depropanizers  that  allow  us  to  extract  propane  from  the  NGL  stream  and  sell
propane to local markets. Additionally, we operate a fractionator at our Waskom plant and sell ethane, propane, butane and natural gasoline to local markets.

Our Anadarko Basin crude oil and condensate gathering assets are located in Oklahoma. These systems were designed and built to serve the crude oil and
condensate production in the SCOOP and STACK plays ( including the area where the SCOOP and STACK come together known as the Merge play) . On our
systems, crude oil and condensate is either received on gathering lines near our customers’ wells or via truck unloading terminals. We do not take title to crude oil
or condensate gathered on our systems. Crude oil and condensate gathered on our Anadarko Basin gathering systems can be redelivered to our customers through
interconnections to the Basin Pipeline, the Red River Pipeline and the CVR Refining, LP refinery located at Wynnewood, Oklahoma (the Wynnewood Refinery).

Our Williston Basin crude oil and produced water gathering assets are located in the Bakken Shale in North Dakota. These systems were designed and built
to  serve  the  crude  oil  production  of  XTO  in  these  areas.  On  our  systems,  crude  oil  is  received  on  crude  oil  gathering  pipelines  near  our  customer’s  wells  for
delivery to third party transportation pipelines, and produced water is received by produced water gathering pipelines for delivery to third party disposal wells. We
do not take title to crude oil or produced water gathered on our systems and we do not own or operate produced water disposal wells. Crude oil gathered on our
Williston Basin gathering systems in Dunn and McKenzie Counties can be redelivered to our customers through interconnections to the BakkenLink Pipeline and
the Dakota Access Pipeline. Crude oil gathered on our Williston Basin gathering systems in Williams and Mountrail Counties can be redelivered to our customer
through interconnections to the Enbridge North Dakota Pipeline and the Dakota Access Pipeline.

Natural  Gas  Gathering  and  Processing  Customers. For  the  year  ended  December  31,  2018  ,  our  top  natural  gas  gathering  and  processing  customers  by
gathered  volumes  were  Continental  Resources,  Inc.  (Continental),  Vine  Oil  and  Gas  (Vine),  GeoSouthern  Energy  Corporation  (GeoSouthern),  XTO,  Tapstone
Energy LLC (Tapstone), Apache Corporation (Apache), BP America Production Company (BP), QEP Resources, Inc. (QEP), FourPoint Energy, LLC (FourPoint)
and Marathon Oil Corporation (Marathon Oil). For the year ended December 31, 2018 , our top ten natural gas producer customers accounted for approximately
70% of our natural gas gathered volumes.

Crude Oil, Condensate and Produced Water Gathering Customers. Our Anadarko Basin crude oil gathering systems gathers crude oil and condensate from
producers, which are primarily delivered to CVR Refining, LP. Our Anadarko Basin crude oil and condensate gathering system is an intrastate pipeline system, and
the rates and terms of service are regulated by the Oklahoma Corporation Commission (OCC). Our Williston Basin crude oil and produced water gathering systems
serve XTO. Crude oil on the Williston Basin systems is delivered for transportation on third party interstate pipeline systems, and produced water is delivered to
third  party  injection  wells.  Our  Williston  Basin  crude  oil  gathering  systems,  but  not  our  produced  water  gathering  systems,  are  considered  interstate  pipeline
systems, and the rates and terms of service are regulated by FERC under the Interstate Commerce Act.

Contracts. Our contracts typically provide for crude oil, condensate and produced water gathering services that are fee-based and for natural gas gathering

and processing arrangements that are fee-based, or percent-of-liquids, percent-of-proceeds or keep-whole based .

•

•

Under a typical fee-based processing arrangement, we process the raw natural gas to extract the NGLs, purchase the NGLs from the producer less a
fee, return the processed natural gas to the producer and sell the NGLs for our own account.

Under a typical percent-of-liquids processing arrangement, we process the raw natural gas to extract the NGLs, purchase the NGLs from the producer
at a discount, return the processed natural gas to the producer and sell the NGLs for our own account.

10

 
 
Table of Contents

•

•

Under a typical percent-of-proceeds processing arrangement, we process the raw natural gas to extract the NGLs, purchase the NGLs and an agreed
upon percentage of the processed natural gas from the producer at a discount, return the remaining processed natural gas to the producer and sell the
purchased natural gas and NGLs for our own account.

Under  a  typical  keep-whole  arrangement,  we  process  raw  natural  gas  to  extract  the  NGLs,  return  a  quantity  of  the  processed  natural  gas  to  the
producer that is equivalent to the raw natural gas on a Btu basis and retain and sell the NGLs for our own account. 

For the year ended December 31, 2018 , 67% , 27% and 6% of our natural gas processing inlet volumes were processed under arrangements that were fee-
based, percent-of-proceeds or percent-of-liquids, and keep-whole, respectively. For the year ended December 31, 2018 , 72% of our gathering and processing gross
margin  was  fee-based,  and  the  remaining  28% of  our  gathering  and  processing  gross  margin  was  primarily  from  sales  of  commodities,  including  natural  gas,
natural gas liquids and condensate received under percent-of-proceeds, percent-of-liquids and keep-whole arrangements.

In lean gas areas, such as the eastern Arkoma Basin and the Haynesville Shale of the Ark-La-Tex Basin, some of our natural gas gathering contracts contain
minimum volume commitments from our customers. Additionally, a portion of the crude oil gathered by our crude oil gathering system in the Williston Basin is
under a contract with a minimum volume commitment. Under a minimum volume commitment, a customer agrees to either deliver a minimum volume of natural
gas or crude oil to our system for service or pay the service fees for the minimum volume of natural gas or crude oil regardless of whether or not the minimum
volume  of  natural  gas  or  crude  oil  is  delivered.  We  call  any  payment  for  the  difference  between  the  volume  gathered  and  the  minimum  volume  committed  a
shortfall payment. Some of our contracts provide our customers the option to elect to pay a higher gathering fee over the remaining term of the contract in lieu of
making  a  shortfall  payment.  As  of  December  31, 2018  ,  the  percentage  of  our  gathering  and  processing  gross  margin  attributable  to  natural  gas  and  crude  oil
gathering contracts with minimum volume commitments, and the volume commitment-weighted average remaining terms of those contracts, were as follows:

For  our  gathering  and  processing  contracts  that  do  not  have  minimum  volume  commitments,  we  strive  to  obtain  acreage  dedications.  Under  an  acreage
dedication, a customer agrees to deliver all of the natural gas, crude oil or condensate produced from a given area to our system for gathering, and, if applicable,
processing. As of December 31, 2018 , the gross acres dedicated under gathering agreements and the volume-weighted average remaining term for all gathering

Construction. Our gathering and processing business involves the construction of gathering and processing assets as needed to serve our existing and new
customers. For example, during the year ended December 31, 2018 , we constructed 400 miles of gathering pipelines, added 109,200 horsepower of compression
and invested $487 million in the construction of gathering and processing assets. This construction included the completion of a rich natural gas pipeline that is
capable of delivering approximately

11

 
 
 
 
 
 
 
 
 
Table of Contents

400 MMcf/d of rich natural gas from the Anadarko Basin to an interconnection with a third-party pipeline that in turn delivers rich natural gas to north Texas,
providing a new market outlet for growing Anadarko Basin production. In conjunction with the construction of the rich natural gas pipeline, we entered into a 10-
year gathering and processing agreement, which became effective on July 1, 2018, with an affiliate of Energy Transfer, LP for 400 MMcf/d of deliveries to the
Godley  Plant  in  Johnson  County,  Texas.  Even  with  the  contracted  400  MMcf/d  of  processing  capacity,  the  Partnership  anticipates  that  there  will  be  a  need  to
resume construction of the previously announced Wildhorse Plant, a cryogenic processing facility we plan to connect to our super-header system in Garvin County
Oklahoma, though likely not before 2020.

Competition. Competition for our gathering and processing systems is primarily a function of gathering rate, processing value, system reliability, fuel rate,
system run time, construction cycle time and prices at the wellhead. Our gathering and processing systems compete with gatherers and processors of all types and
sizes,  including  those  affiliated  with  various  producers,  other  major  pipeline  companies  and  various  independent  midstream  entities.  In  the  process  of  selling
NGLs, we compete against other natural gas processors extracting and selling NGLs. Our primary competitors are other midstream companies who are active in
the regions where we operate.

Seasonality .  While  the  results  of  our  gathering  and  processing  segment  are  not  materially  affected  by  seasonality,  from  time  to  time  our  operations  and

construction of assets can be impacted by inclement weather.

Acquisitions. In the fourth quarter of 2018, we acquired Velocity Holdings, LLC, a midstream company with a crude oil and condensate gathering system in
the SCOOP and STACK plays of the Anadarko Basin, and renamed it Enable Oklahoma Crude Services, LLC (EOCS). The acquisition included approximately
150 miles of crude oil and condensate gathering pipelines capable of flowing approximately 225,000 Bbl/d across Grady, Stevens, Garvin and McClain counties in
Oklahoma. A portion of EOCS’s operations are conducted through a joint venture with a subsidiary of CVR Refining, LP in which EOCS owns 60% of the joint
venture  and  operates  its  assets.  Crude  oil  and  condensate  gathered  on  the  system  can  be  redelivered  to  our  customers  through  interconnections  to  the  Basin
Pipeline, the Red River Pipeline and the Wynnewood Refinery. For the year ended December 31, 2018 , 78% of crude oil and condensate gathered on the system
was delivered to the Wynnewood Refinery.

Transportation and Storage

We own and operate interstate and intrastate natural gas transportation and storage systems across nine states. Our transportation and storage systems consist
primarily  of  our  interstate  systems,  EGT  and  MRT,  our  intrastate  system,  EOIT,  and  our  investment  in  SESH.  Our  transportation  and  storage  assets  transport
natural gas from areas of production and interconnected pipelines to power plants, LDCs and industrial end users as well as interconnected pipelines for delivery to
additional markets. Our transportation and storage assets also provide facilities where natural gas can be stored by customers.

 Our transportation and storage assets were designed and built to primarily serve large natural gas and electric utilities in our areas of operation. In addition,
our transportation and storage assets serve natural gas producers, industrial end users and natural gas marketers. For the year ended December 31, 2018 , our top
transportation and storage customers by revenue were affiliates of CenterPoint Energy, Spire Inc. (Spire), Continental, American Electric Power Co. (AEP), OGE
Energy, Chesapeake Energy Corp., LS Power, Midcontinent Express Pipeline LLC (MEP), Entergy Corporation (Entergy) and Black Hills Corporation.

From  time  to  time,  our  transportation  and  storage  business  involves  the  construction  of  natural  gas  pipelines  as  needed  to  serve  our  existing  and  new
customers. For example, during the year ended December 31, 2018 , we added 8,700 horsepower of compression and invested $126 million in the construction of
transportation  pipelines,  including  the  Cana  and  STACK  Expansion  (CaSE)  project,  a  system  expansion  providing  firm  transportation  service  for  growing
Anadarko  Basin  production,  and  an  approximately  80-mile  pipeline  expanding  the  EOIT  system  to  provide  service  to  the  OGE  Energy  Muskogee,  Oklahoma
power plant. In addition, in September 2018, we announced the development of the Gulf Run Pipeline, an interstate natural gas transportation project. The Gulf
Run Pipeline project is designed to connect U.S. natural gas supplies to the liquefied natural gas (LNG) export market on the Gulf Coast.

Our  transportation  assets  include  approximately  10,090 miles  of  transportation  pipelines  in  Texas,  Oklahoma,  Arkansas,  Louisiana,  Kansas,  Mississippi,
Alabama,  Missouri  and  Illinois  (including  SESH),  providing  access  to  natural  gas  supplies  from  the  Anadarko,  Arkoma  and  Ark-La-Tex  Basins  to  natural  gas
consuming markets in the Southeastern, Northeastern and Midwestern United States. Our storage assets, as of December 31, 2018 , provide a combined capacity of
84.5 Bcf with 2.0 Bcf/d of aggregate maximum withdrawal capacity from our seven storage facilities in Oklahoma, Louisiana and Illinois and from our undivided
1/12th interest in the Bistineau Storage Facility in Louisiana. Boardwalk Pipeline Partners, LP owns an undivided 11/12th interest in, and operates, the Bistineau
Storage Facility.

Our transportation and storage assets are comprised of three categories: (1) interstate transportation and storage, (2) intrastate transportation and storage and

(3) our investment in SESH.

Interstate Transportation and Storage

Our interstate transportation and storage business consists of EGT and MRT. As interstate pipelines, EGT and MRT are subject to regulation as natural gas

companies by FERC under the NGA.

EGT

EGT  provides  natural  gas  transportation  and  storage  services  primarily  to  customers  in  Oklahoma,  Texas,  Arkansas,  Louisiana,  Missouri  and  Kansas.  In
addition to 5,900 miles of interstate pipelines with capacity of 6.0 Bcf/d, EGT has two underground natural gas storage facilities in Oklahoma and one underground
natural gas storage facility in Louisiana, which, as of December 31, 2018 , operate at a combined capacity of 29.0 Bcf with 739 MMcf/d of aggregate maximum
withdrawal capacity.

Interconnections and Delivery Points. In addition to delivering natural gas to utilities and industrial end users in Oklahoma, Louisiana, Texas and Arkansas,
EGT  receives  natural  gas  from  and  delivers  natural  gas  to  a  variety  of  intrastate  and  interstate  pipelines  through  its  numerous  interconnections.  Those
interconnections include SESH, ANR, Columbia Gulf, EOIT, Gulf South, MEP, MRT, SONAT, Tennessee Gas, Texas Eastern, Texas Gas and Trunkline. Through
EGT’s interconnection with SESH, our customers have access to the Southeast power generation market. Through our interconnections with other pipelines, our
customers  have  access  to  the  Midwest  and  Northeast  markets.  Many  of  EGT’s  interconnections  are  at  our  Perryville  Hub,  which  provides  the  ability  to  move
natural gas between 11 major interstate pipelines. As a result, EGT provides our customers with access to not only natural gas consuming markets in Oklahoma,
Louisiana, Texas and Arkansas, but also most of the major natural gas consuming markets east of the Mississippi River. In addition, EGT provides our customers
supplying those markets with access to natural gas from producing basins and shale plays across the Mid-continent, including the Anadarko, Arkoma and Ark-La-
Tex Basins and the Barnett, Fayetteville, Granite Wash, Haynesville, SCOOP and STACK plays.

Customers. EGT primarily serves LDCs owned by CenterPoint Energy, producers in key plays in the Mid-continent, power plants, other LDCs and industrial
end-users. EGT’s customers are primarily located in Arkansas, Louisiana, Oklahoma and Texas. For the year ended December 31, 2018 , approximately 28% of
EGT’s service revenue was attributable to contracts with LDCs

14

  
 
Table of Contents

owned by CenterPoint Energy with a volume-weighted average contract life of 2.3 years for transportation contracts and 2.3 years for storage contracts. In addition
to CenterPoint Energy’s LDCs, EGT’s other major customers include Continental and AEP.

Contracts. Although EGT has established maximum rates for interstate transportation and storage services as required by FERC, EGT is authorized to enter
into  negotiated  rate  and  discounted  rate  agreements  with  its  customers.  EGT’s  services  are  typically  provided  under  firm,  fee-based  transportation  and  storage
agreements. For the year ended December 31, 2018 , approximately 54% of our transportation and storage gross margin was derived from EGT’s firm contracts,
72% of EGT’s transportation capacity was under firm contracts with a volume-weighted average remaining contract life of 3.0 years, and 81% of EGT’s storage
capacity was under firm contracts with a volume-weighted average remaining contract life of 2.3 years. All of EGT’s firm transportation and storage contracts for
CenterPoint  Energy’s  LDCs  are  scheduled  to  expire  in  March  2021.  CenterPoint’s  LDCs  have  initiated  proceedings  before  the  state  utility  commissions  in
Arkansas and Oklahoma to consider whether contracts extending transportation and storage services with EGT would be more favorable than the expected results
of  competitive  bidding  for  the  same  services.  If  the  proposed  contracts  are  approved,  then  the  term  for  the  transportation  and  storage  services  provided  to
CenterPoint  Energy’s  LDCs  in  Arkansas,  Louisiana,  Oklahoma  and  Northeast  Texas  will  be  extended  beyond  March  31,  2021,  pursuant  to  the  terms  of  the
approved contracts.

Seasonality.  Customer  demand  for  natural  gas  from  EGT  is  usually  greater  during  the  winter,  primarily  due  to  LDC  demand  to  serve  residential  and
commercial natural gas requirements. In addition, EGT experiences seasonal impacts associated with storage spreads and basis spreads on interconnected pipelines,
as well as power plant demand.

Competition. EGT competes with a variety of other interstate and intrastate pipelines across Texas, Oklahoma, Arkansas and Louisiana. Our management
views  the  principal  elements  of  competition  among  pipelines  as  rates,  terms  of  service,  flexibility  and  reliability  of  service.  EGT  provides  both  flexibility  and
reliability of service with access to multiple sources of supply in the Anadarko, Arkoma and Ark-La-Tex Basins and access to multiple markets in the Midwest,
Northeast and Southeast through interconnections with other pipelines.

MRT

MRT provides natural gas transportation and storage services principally in Texas, Arkansas, Louisiana, Missouri and Illinois. In addition to 1,600 miles of
interstate pipelines with capacity of 1.7 Bcf/d, MRT has one underground natural gas storage facility in Louisiana, which includes the East Unionville and West
Unionville fields, and one underground natural gas storage facility in Illinois, which, as of December 31, 2018 , operate at a combined capacity of 31.5 Bcf with
590 MMcf/d of aggregate maximum withdrawal capacity.

Interconnections  and  Delivery  Points.  MRT  receives  natural  gas  from  a  variety  of  interstate  and  intrastate  pipelines  through  its  interconnections  and  delivers
natural gas primarily to the St. Louis market. Those interconnections include EGT, Gulf South, NGPL, Ozark Gas Transmission, Texas Eastern, Texas Gas and
Trunkline . From MRT’s west line, we provide our customers with access to supply from East Texas and North Louisiana, including the Haynesville Shale. From
MRT’s  mainline,  we  provide  our  customers  with  access  to  supply  from  the  Anadarko,  Arkoma  and  Ark-La-Tex  Basins.  Supply  from  the  Fayetteville  Shale  is
transported though our interconnection with EGT, Texas Gas and Ozark Gas Transmission. From MRT’s east line, we provide our customers with access to supply
from the Mid-continent and the Marcellus Shale through our interconnections  with NGPL and Trunkline. As a result, MRT provides the St. Louis market with
access to natural gas from a variety of major producing basins across the U.S.

Customers  .  MRT  primarily  serves  the  St.  Louis  LDC  owned  by  Spire.  For  the  year  ended  December  31,  2018  ,  70%  of  MRT’s  service  revenue  was
attributable  to  Spire  under  contracts  with  a  volume-weighted  average  contract  life  of  1.0  year  for  transportation  contracts  and  1.1  years  for  storage  contracts.
MRT’s other customers include utilities and industrial end users. MRT’s customers are primarily located in Arkansas, Missouri and Illinois.

Contracts . MRT’s services are typically provided under firm, fee-based transportation and storage agreements, with rates and terms of service regulated by
FERC. For the year ended December 31, 2018 , approximately 13% of our transportation and storage gross margin was derived from MRT’s firm contracts, 89%
of  MRT’s  transportation  capacity  was  under  firm  contracts  with  a  volume-weighted  average  remaining  contract  life  of  1.5  years  and  96%  of  MRT’s  storage
capacity was under firm contracts with a volume-weighted average remaining contract life of 1.2 years. MRT’s firm transportation contracts representing 63% of
Spire’s firm transportation capacity are scheduled to expire in July 2019 and 37% of Spire’s firm transportation capacity are scheduled to expire in July 2020. 32%
of Spire’s firm storage contracts are scheduled to expire in May 2019 and 68% of Spire’s firm storage contracts are schedule to expire in May 2020.

On August 3, 2018, the FERC approved a Certificate of Public Convenience and Necessity for the Spire STL Pipeline. The Spire STL Pipeline will be an
additional interstate pipeline serving Spire’s affiliates in the St. Louis market. Spire has indicated that it is targeting a 2019 in-service date for this pipeline. When
the pipeline is placed in-service, we anticipate that Spire’s LDC’s need for firm transportation and storage capacity on MRT will decrease.

Seasonality.  Customer  demand  for  natural  gas  on  MRT  is  usually  greater  during  the  winter,  primarily  due  to  LDC  demand  to  serve  residential  and
commercial natural gas requirements. In addition, MRT experiences seasonal impacts associated with storage spreads and basis spreads on market-based pipelines.

Competition. MRT competes with various intrastate pipelines providing natural gas to the St. Louis market. In addition, Spire’s LDC is expected to switch an
undetermined amount of demand to its affiliate, the interstate Spire STL Pipeline, when constructed. Our management views the principal elements of competition
among  pipelines  as  rates,  terms  of  service,  flexibility  and  reliability  of  service.  MRT,  through  its  interconnections  with  a  variety  of  interstate  and  intrastate
pipelines and its access to supply from a variety of producing basins, provides our customers with access to a variety of natural gas supply sources.

Intrastate Transportation and Storage

Our intrastate natural gas transportation and storage assets consist primarily of EOIT. EOIT provides transportation and storage services in Oklahoma. Our
EOIT system delivers natural gas from the Anadarko and Arkoma Basins, including the SCOOP, STACK, Cana Woodford, Granite Wash, Cleveland, Tonkawa,
and  Mississippi  Lime  Shale  plays  in  western  Oklahoma  and  the  Texas  Panhandle,  to  utilities  and  industrial  end  users  connected  to  EOIT  and  to  interstate  and
intrastate pipelines interconnected with EOIT. EOIT had 2.08 TBtu/d of average daily throughput for the year ended December 31, 2018 . In addition to 2,300
miles of intrastate pipelines, EOIT has two underground natural gas storage facilities in Oklahoma, which, as of December 31, 2018 operate at a combined capacity
of 24 Bcf with 605 MMcf/d of aggregate max imum withdrawal capacity.

Interconnections  and  Delivery  Points.  EOIT  has  79  interconnections,  which  include  interconnects  with  EGT  and  12  third-party  interstate  and  intrastate
natural  gas  pipelines,  including  ANR  Pipeline,  El  Paso  Natural  Gas  Pipeline,  Gulf  Crossing  Pipeline  Company  LLC,  MEP,  Natural  Gas  Pipeline  Company  of
America,  Northern  Natural  Gas  Company,  ONEOK Gas  Transmission,  Ozark  Gas  Transmission,  L.L.C.,  Panhandle  Eastern  Pipe  Line,  Postrock  KPC Pipeline,
LLC, Southern Star Central Gas Pipeline

Table of Contents

and ONEOK Western Trails Pipeline, L.L.C. In addition, EOIT connects to 44 end-user customers, including 14 natural gas-fired electric generation facilities in
Oklahoma.

Customers.  EOIT’s  customers  include  Oklahoma’s  two  largest  electric  utilities,  OG&E,  an  affiliate  of  OGE  Energy  and  Public  Service  Company  of
Oklahoma  (PSO),  an  affiliate  of  AEP.  For  the  year  ended  December  31,  2018  ,  approximately  7%  of  our  total  transportation  and  storage  gross  margin  was
attributable to firm contracts with OG&E, and approximately 3% of our transportation and storage gross margin was attributable to a firm contract with PSO. Our
no-notice  load-following  transportation  agreement  with  OG&E  for  three  of  its  generating  facilities  was  scheduled  to  terminate  on  April  1,  2019  and  has  been
recontracted to extend through May 1, 2024 and will remain in effect year to year thereafter unless either party provides notice of termination to the other party at
least  180  days  prior  to  the  commencement  of  the  succeeding  annual  period.  Our  firm  transportation  agreement  with  OG&E,  for  one  of  its  generating  facilities
began on December 1, 2018 and extends through December 1, 2038. Our transportation agreement with PSO extends through December 31, 2020 and includes the
option for a one-year extension. EOIT’s customers also include other electric generators, LDCs, Arkoma and Anadarko Basin producers and industrial end users.

Contracts. EOIT provides fee-based firm and interruptible transportation and storage services on both an intrastate basis and, pursuant to Section 311 of the
NGPA, on an interstate basis. For the year ended December 31, 2018 , approximately 21% of our transportation and storage gross margin was derived from EOIT’s
firm contracts. EOIT’s transportation capacity was under firm contracts with a volume-weighted average remaining contract life of 6.0 years and EOIT’s storage
capacity was under firm contracts with a volume-weighted average remaining contract life of 1.0 years.

Seasonality. EOIT provides gas transmission delivery services to the majority of OG&E’s and all of PSO’s natural gas-fired electric generation facilities in
Oklahoma. Customer demand for natural gas transportation and storage services on EOIT is usually greater during the summer, primarily due to demand by natural
gas-fired power plants to serve residential and commercial electricity requirements.

Competition .  EOIT competes  with  a  variety  of  interstate  and  intrastate  pipelines  in  providing  transportation  and  storage  services  in  Oklahoma,  including
competing against several pipelines with which EOIT interconnects. We view competition in the transportation and storage market as primarily a function of rates,
terms of services, flexibility and reliability of service. EOIT’s integrated transportation and storage system allows us to provide load following service to natural
gas-fired power plants to allow the power plants the ability to regulate generation and meet the instantaneous changes in customer demand for electricity.

Our Investment in SESH

SESH is an approximately 290 -mile interstate pipeline that provides transportation services in Louisiana, Mississippi and Alabama. We own a 50% interest
in SESH and provide field operations for the pipeline. Enbridge Inc. owns the remaining 50% interest in SESH and provides gas control and commercial operations
for the pipeline. As of December 31, 2018 , SESH had 1.09 Bcf/d of transportation capacity from Perryville, Louisiana to its endpoint in Mobile County, Alabama.

18

 
 
 
Table of Contents

Interconnections and Delivery Points . SESH runs from the Perryville Hub in northeastern Louisiana to southwestern Alabama near the Gulf Coast. SESH
has  20  interconnects  with  third-party  natural  gas  pipelines  and  provides  access  to  major  Southeast  and  Northeast  markets.  Natural  gas  transported  by  SESH  is
primarily transported by the interconnecting pipelines to companies generating electricity for the Florida power market. SESH also interconnects with three high-
deliverability storage facilities, Mississippi Hub Storage, Petal Gas Storage and Southern Pines Energy Center.

Customers and Contracts . SESH’s customers are primarily companies that generate electricity for the Florida power market. The rates charged by SESH for
interstate transportation services are regulated by FERC. SESH’s transportation services are typically provided under firm, fee-based negotiated rate agreements.
SESH’s transportation contracts have a volume-weighted average remaining contract life of 3.8 years.

Seasonality . SESH is generally not impacted by seasonality. SESH’s load factor generally remains constant throughout the year.

Competition. SESH  competes  with  other  interstate  and  intrastate  pipelines  providing  access  to  the  Southeast  power  generation  market.  Our  management

views the principal elements of competition among pipelines as rates and terms, flexibility and reliability of service.

Rate and Other Regulation

Federal, state and local regulation of pipeline gathering and transportation services may affect certain aspects of our business and the market for our products

and services.

Interstate
Natural
Gas
Pipeline
Regulation

EGT, MRT and SESH are subject to regulation by FERC and are considered “natural gas companies” under the Natural Gas Act (NGA). The NGA prohibits
natural gas companies from granting any undue preference or advantage, or unduly discriminating against any person with respect to pipeline rates or terms and
conditions of service, including unduly discriminatory or preferential access to information. FERC authority over natural gas companies that provide natural gas
pipeline transportation services in interstate commerce includes:

•

•

•

rates, terms and conditions of service and service contracts;

certification and construction of new facilities or expansion of existing facilities;

abandonment of facilities;

• maintenance of accounts and records;

•

•

•

•

acquisition and disposition of facilities;

initiation, extension or abandonment of services;

accounting, depreciation and amortization policies;

conduct and relationship with certain affiliates;

• market manipulation in connection with the purchase or sale of natural gas or transportation in interstate commerce; and

•

various other matters.

Under the NGA, the rates for service on interstate facilities must be just and reasonable and not unduly discriminatory. Generally, the maximum recourse
rates for interstate pipelines are based on the pipeline’s cost of service including recovery of and a return on the pipeline’s actual prudent investment cost. Key
determinants in the ratemaking process are the total costs of providing service, allowed rate of return and throughput projections. Our interstate pipeline operations
may be affected by changes in the demand for natural gas, the available supply and relative price of natural gas in the Mid-continent and Gulf Coast natural gas
supply regions and general economic conditions.

Rate and tariff changes can only be implemented upon approval by FERC. Two primary methods are available for changing the rates, terms and conditions
of service of an interstate natural gas pipeline. Under the first method, the pipeline voluntarily seeks a rate or tariff change by making a filing with FERC justifying
the  proposed  change.  FERC  provides  notice  of  the  proposed  change  to  the  public  through  publication  on  its  website  and  in  the  Federal  Register  .  If  FERC
determines that a proposed change is just and reasonable, FERC grants approval of and allows the pipeline to implement the change. If FERC determines that a
proposed change may not be just and reasonable, FERC may suspend the proposed change for up to five months. Subsequent to any suspension period ordered by
FERC, the proposed change may be placed into effect by the company, pending final FERC approval. In most cases, a proposed rate change is placed into effect
before a final FERC determination on such rate change, and the pipeline is permitted to collect the proposed rate subject to refund (plus interest). Under the second
method, FERC may, on its own motion or based on a complaint filed by a third party, initiate a proceeding seeking to compel the company to change its rates,
terms and/or conditions of service. If FERC determines that the existing rates, terms and/or conditions of service are unjust, unreasonable, unduly discriminatory or
preferential, then any rate reduction or change that it orders generally will be effective prospectively from the date of the FERC order requiring this change.

Effective December 22, 2017, the Tax Cuts and Jobs Act of 2017 (Tax Cuts and Jobs Act) changed several provisions of the federal tax code, including a
reduction in the maximum corporate tax rate. On March 15, 2018, in a set of related issuances, FERC addressed treatment of federal income tax allowances in
regulated entity rates. FERC issued a Revised Policy Statement on Treatment of Income Taxes stating that it will no longer permit pipelines organized as master
limited partnerships to recover an income tax allowance in their cost-of-service rates. FERC issued the Revised Policy Statement in response to a remand from the
U.S. Court of Appeals for the D.C. Circuit in United Airlines v. FERC, in which the court determined that FERC had not justified its conclusion that a pipeline
organized as a master limited partnership would not “double recover” its taxes under the current policy by both including an income-tax allowance in its cost-of-
service  and  earning  a  return  on  equity  calculated  using  the  discounted  cash  flow  methodology.  On  July  18,  2018,  FERC  issued  an  order  denying  requests  for
rehearing of its Revised Policy Statement because it is a non-binding policy and parties will have the opportunity to address the policy as applied in future cases. In
the  rehearing  order,  FERC  clarified  that  a  pipeline  organized  as  a  master  limited  partnership  will  not  be  precluded  in  a  future  proceeding  from  arguing  and
providing evidentiary support that it is entitled to an income tax allowance and demonstrating that its recovery of an income tax allowance does not result in a
double-recovery of investors’ income tax costs. FERC also provided guidance that when a master limited partnership pipeline’s income tax allowance is eliminated
from cost of service, previously accumulated deferred income taxes (ADIT) may also be eliminated as ADIT is not a true-up or tracker of money owed shippers.

20

 
 
Table of Contents

FERC also issued a Notice of Inquiry (NOI) requesting comments on the effect of the Tax Cuts and Jobs Act on FERC-jurisdictional rates. The NOI states
that of particular interest to FERC is whether, and if so how, FERC should address changes relating to ADIT and bonus depreciation. Comments in response to the
NOI were due on or before May 21, 2018. Actions FERC will take, if any, following receipt of responses to the NOI and any potential impacts from final rules or
policy statements issued following the NOI on the rates the Partnership can charge for transportation services are unknown at this time, but could impact rates the
Partnership is permitted to charge its customers.

Included  in  the  issuances  on  March  15,  2018,  is  a  Notice  of  Proposed  Rulemaking  (NOPR)  proposing  rules  for  implementation  of  the  Revised  Policy
Statement and the corporate income tax rate reduction with respect to natural gas pipeline rates. On July 18, 2018, FERC issued a Final Rule adopting procedures
that  are  generally  the  same  as  proposed  in  the  NOPR  with  a  few  clarifications  and  modifications.  With  limited  exceptions,  the  Final  Rule  requires  all  FERC-
regulated natural gas pipelines that have cost-based rates for service to make a one-time Form No. 501-G filing providing certain financial information. The Final
Rule states that this information will allow FERC and other stakeholders to evaluate the impacts of the Tax Cuts and Jobs Act and the Revised Policy Statement on
each  individual  pipeline’s  rates.  The  Final  Rule  also  requires  that  each  FERC-regulated  natural  gas  pipeline  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 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. For the limited NGA
Section  4  option,  FERC  clarified  that,  notwithstanding  the  Revised  Policy  Statement,  a  pipeline  organized  as  a  master  limited  partnership  does  not  need  to
eliminate its income tax allowance but, instead, can reduce its rates to reflect the reduction in the maximum corporate tax rate. At this time, we cannot predict the
outcome of the Final Rule, but FERC’s adoption of the regulation could impact the rates the Partnership’s FERC-regulated entities are permitted to charge their
customers. EGT filed its Form No. 501-G on October 11, 2018. On November 8, 2018, SESH filed its Form No. 501-G and a limited Section 4 rate reduction
filing. As MRT had already filed a rate proceeding under NGA Section 4 pursuant to a schedule agreed upon in the settlement of MRT’s last rate case, MRT was
not required to make any filing on the FERC’s Form No. 501-G.

Even without action on the NOI or as contemplated in the Final Rule, the FERC or our shippers may challenge the cost‑of‑service rates we charge. FERC’s
establishment of a just and reasonable rate is based on many components, and tax-related changes will affect tax-related accounts, such as the annual allowance for
income taxes and the balance sheet amounts for accumulated deferred income taxes and related regulatory assets and liabilities, while other pipeline costs also will
continue to affect FERC’s determination of just and reasonable cost-of-service rates. Although changes in these tax-related accounts may vary, other components
in the cost-of-service rate calculation may also change and result in a newly calculated cost-of-service rate that is the same as or greater than the prior cost-of-
service rate. Moreover, pipelines receive revenues from cost-of-service rates, negotiated rates, discounted rates, and market-based rates, or a combination thereof.
As of December 31, 2018 , approximately 59% of our aggregate contracted firm transportation capacity on EGT was subscribed under negotiated rate contracts and
approximately  100%  of  our  aggregate  contracted  firm  storage  capacity  on  EGT  was  subscribed  under  negotiated  rate  contracts.  As  of  December  31,  2018  ,
approximately 2% of our aggregate contracted firm transportation capacity on MRT was subscribed under negotiated rate contracts and our aggregated contracted
firm  storage  capacity  on  MRT  was  not  subscribed  under  negotiated  rate  contracts.  As  of  December  31, 2018  ,  approximately  28%  and  36%  of  our  aggregate
contracted  firm  transportation  capacity  on  EGT  and  MRT,  respectively,  was  subscribed  under  discounted  rate  contracts.  We  do  not  expect  rates  subject  to
negotiated rates that are not tied to the cost-of-service rates to be affected by the Revised Policy Statement or any final regulations that may result from the March
15, 2018 issuances. Nor will discounted rates which are below the level of any new maximum rate be affected. With respect to the cost-of-service rates, depending
on a detailed review of all of the Partnership’s cost-of-service components and the outcomes of any challenges to our rates by the FERC or our shippers, the NOI,
the  Final  Rule,  and  the  Revised  Policy  Statement,  combined  with  the  reduced  corporate  federal  income  tax  rate  established  in  the  Tax  Cuts  and  Jobs  Act,  the
revenues associated with natural gas transportation services we provide pursuant to cost-of-service based rates may decrease in the future.

The FERC issued a Notice of Inquiry on April 19, 2018 (April 2018 NOI), thereby initiating a review of its policies on certification of natural gas pipelines,
including an examination of its long-standing Policy Statement on Certification of New Interstate Natural Gas Pipeline Facilities, issued in 1999, that is used to
determine whether to grant certificates for new pipeline projects. We are unable to predict what, if any, changes may be proposed as a result of the April 2018 NOI
that will affect our natural gas pipeline business or when such proposals, if any, might become effective. We do not expect that any change in this policy would
materially affect our plans and operations.

MRT Rate Case

On June 29, 2018, MRT filed a general rate case with the FERC pursuant to Section 4 of the Natural Gas Act. 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,  and  changes  to  the  Small  Customer  service  rate  schedule.  Consistent  with  the  previously  mentioned  order  on
rehearing of the FERC’s Revised

21

Table of Contents

Policy Statement, as a pipeline owned by an MLP, MRT also filed to recover an income tax allowance, arguing and providing evidentiary support that it is entitled
to  an  income  tax  allowance.  A  number  of  customers  filed  notices  of  intervention  and  protests,  and  on  July  31,  2018,  FERC  issued  an  Order  Accepting  and
Suspending  Tariff  Records  Subject  to  Refund  and  Condition  and  Establishing  Hearing  and  Settlement  Judge  Procedures  and  a  Technical  Conference  (July  31
Order).  In  the  July  31  Order,  FERC  ordered  MRT  to  refile  its  rate  case  within  30  days  of  the  date  of  the  July  31  Order  to  reflect,  among  other  things,  the
elimination of an income tax allowance from its costs used to calculate MRT’s rates pursuant to the Revised Policy Statement. On August 30, 2018, MRT made its
filing to comply with the FERC’s July 31 Order and also sought rehearing of certain aspects of the July 31, Order, and FERC accepted the filing on December 7,
2018. The elimination of the income tax allowance as mandated by FERC, when coupled with the corresponding elimination of ADIT, had a de minimis impact on
MRT’s overall  cost  of service.  MRT has, nevertheless,  requested  rehearing  of the July 31 Order, and on September  14, 2018, MRT also filed an appeal  of the
Revised Policy statement with the United States Court of Appeals for the District of Columbia Circuit, on the grounds that the Revised Policy Statement was, in
fact, not being applied as a policy subject to individual pipelines being able to argue and provide evidentiary support for an income tax allowance, but, rather, was
being applied as a rule and as an absolute bar to pipelines organized or owned by MLPs being able to recover an income tax allowance.

Market
Behavior
Rules;
Posting
and
Reporting
Requirements

On August 8, 2005, Congress enacted the EPAct of 2005. Among other matters, the EPAct of 2005 amended the NGA to add an anti-manipulation provision
that makes it unlawful for any entity to engage in prohibited behavior in contravention of rules and regulation to be prescribed by FERC and, furthermore, provides
FERC  with  additional  civil  penalty  authority.  On  January  19,  2006,  FERC  issued  Order  No.  670,  a  rule  implementing  the  anti-manipulation  provisions  of  the
EPAct of 2005. The rules make it unlawful for any entity, directly or indirectly in connection with the purchase or sale of natural gas subject to the jurisdiction of
FERC or the purchase or sale of transportation services subject to the jurisdiction of FERC, to (1) use or employ any device, scheme or artifice to defraud; (2) to
make any untrue statement of material fact or omit to make any such statement necessary to make the statements not misleading; or (3) to engage in any act or
practice that operates as a fraud or deceit upon any person. The anti-manipulation rules apply to interstate gas pipelines and storage companies and intrastate gas
pipelines  and  storage  companies  that  provide  interstate  services,  such  as  Section  311  service,  as  well  as  otherwise  non-jurisdictional  entities  to  the  extent  the
activities  are  conducted  “in  connection  with”  gas  sales,  purchases  or  transportation  subject  to  FERC  jurisdiction.  The  anti-manipulation  rules  do  not  apply  to
activities  that  relate  only  to  intrastate  or  other  non-jurisdictional  sales  or  gathering  to  the  extent  such  transactions  do  not  have  a  “nexus”  to  jurisdictional
transactions. The EPAct of 2005 also amends the NGA and the NGPA to give FERC authority to impose civil penalties for violations of these statutes and FERC’s
regulations,  rules  and  orders,  up  to  approximately  $1.27  million  per  day  per  violation  for  violations  occurring  after  August  8,  2005.  This  maximum  penalty
authority  established  by  statute  will  continue  to  be  adjusted  periodically  for  inflation.  In  connection  with  this  enhanced  civil  penalty  authority,  FERC  issued  a
revised  policy  statement  on  enforcement  to  provide  guidance  regarding  the  enforcement  of  the  statutes,  orders,  rules  and  regulations  it  administers,  including
factors to be considered in determining the appropriate enforcement action to be taken. If we fail to comply with all applicable FERC-administered statutes, rules,
regulations and orders, we could be subject to substantial penalties and fines. In addition, the CFTC is directed under the Commodities Exchange Act, or CEA, to
prevent price manipulations for the commodity and futures markets, including the energy futures markets. Pursuant to the Dodd-Frank Act and other authority, the
CFTC  has  adopted  anti-market  manipulation  regulations  that  prohibit  fraud  and  price  manipulation  in  the  commodity  and  futures  markets.  The  CFTC  also  has
statutory  authority  to  seek  civil  penalties  of  up  to  the  greater  of  $1.2  million  or  triple  the  monetary  gain  to  the  violator  for  violations  of  the  anti-market
manipulation sections of the CEA.

The EPAct of 2005 also added Section 23 to the NGA, authorizing FERC to facilitate price transparency in markets for the sale or transportation of physical
natural  gas  in  interstate  commerce.  In  2007,  FERC  took  steps  to  enhance  its  market  oversight  and  monitoring  of  the  natural  gas  industry  by  issuing  several
rulemaking orders designed to promote gas price transparency and to prevent market manipulation. In December 2007, FERC issued a final rule on the annual
natural  gas  transaction  reporting  requirements,  as  amended  by  subsequent  order  on  rehearing,  or  Order  No.  704.  Order  No.  704  requires  buyers  and  sellers  of
annual quantities of natural gas of 2,200,000 MMBtu or more, including entities not otherwise subject to FERC’s jurisdiction, to provide by May 1 of each year an
annual report to FERC describing their aggregate volumes of natural gas purchased or sold at wholesale in the prior calendar year to the extent such transactions
utilize, contribute to or may contribute to the formation of price indices. Order No. 704 also requires market participants to indicate whether they report prices to
any index publishers and, if so, whether their reporting complies with FERC’s policy statement on price reporting. In June 2010, FERC issued the last of its three
orders on rehearing and clarification further clarifying its requirements.

Intrastate

Gas
Pipeline
and
Storage
Regulation

In Oklahoma, our intrastate  pipeline  system (EOIT) is subject to limited  regulation  by the OCC. Oklahoma has a non-discriminatory  access requirement,

which is subject to a complaint-based review. EOIT’s rates and terms of service are not subject to regulation by the OCC.

Intrastate natural gas transportation is largely regulated by the state in which the transportation takes place. An intrastate natural gas pipeline system may
transport  natural gas in interstate  commerce  provided that the rates, terms and conditions of such transportation  service  comply with FERC’s regulations  under
Section 311 of the NGPA and Part 284 of the FERC’s regulations. The NGPA regulates, among other things, the provision of transportation and storage services
by an intrastate natural gas pipeline on behalf of an interstate natural gas pipeline or a LDC served by an interstate natural gas pipeline. Under Section 311, rates
charged for transportation must be fair and equitable, and amounts collected in excess of fair and equitable rates are subject to refund with interest. The rates under
Section 311 are maximum rates and an intrastate pipeline may agree to discount contractual rates at or below such maximum rates. Rates for service pursuant to
Section 311 of the NGPA are generally subject to review and approval by FERC at least once every five years. Should the FERC determine not to authorize rates
equal to or greater than our currently approved Section 311 rates, our business may be adversely affected.

Failure  to  observe  the  service  limitations  applicable  to  transportation  services  provided  under  Section  311,  failure  to  comply  with  the  rates  approved  by
FERC for Section 311 service, or failure to comply with the terms and conditions of service established in the pipeline’s FERC-approved Statement of Operating
Conditions could result in the assertion of federal NGA jurisdiction by FERC and/or the imposition of administrative, civil and criminal penalties, as described in
the “—Interstate Natural Gas Pipeline Regulation” section above.

EOIT currently has two zones under its Section 311 transportation rate structure—an East Zone and a West Zone. For Section 311 service, EOIT may charge
up to its maximum established zonal East and West interruptible transportation rates for interruptible transportation in one zone or cumulative maximum rates for
transportation in both zones. Finally, EOIT may charge the applicable fixed zonal fuel percentage(s) for the fuel used in transporting natural gas under Section 311
on our system. The fixed zonal fuel percentages are the same for firm and interruptible Section 311 services.

Under FERC Order No. 735, intrastate pipelines providing transportation services under Section 311 of the NGPA are required to report on a quarterly basis
via  FERC  Form  549D  more  detailed  information  and  storage  transaction  information,  including:  rates  charged  by  the  pipeline  under  each  contract;  receipt  and
delivery points and zones or segments covered by each contract; the quantity of natural gas the shipper is entitled to transport, store, or deliver; the duration of the
contract; and whether there is an affiliate relationship between the pipeline and the shipper. Order No. 735 further requires that such information must be supplied
through an electronic reporting system and will be posted on FERC’s website, and that such quarterly reports may not contain information redacted as privileged.
FERC  promulgated  this  rule  after  determining  that  such  transactional  information  would  help  shippers  make  more  informed  purchasing  decisions  and  would
improve the ability of both shippers and FERC to monitor actual transactions for evidence of market power or undue discrimination. Order No. 735 also extends
FERC’s periodic  review  of the rates  charged  by the  subject  pipelines  from  three  to five  years.  In Order No. 735-A, FERC generally  reaffirmed  Order No. 735
requiring  Section  311  to  report  on  a  quarterly  basis  storage  and  transportation  transactions  containing  specific  information  for  each  transaction,  aggregated  by
contract. Our intrastate storage assets at the Wetumka Storage Field offer both fee-based firm and interruptible storage services under Section 311 of the NGPA
pursuant  to  terms  and  conditions  specified  in  our  statement  of  operating  conditions  for  gas  storage  at  market-based  rates.  Our  intrastate  Stuart  Storage  Field
currently is used exclusively to provide intrastate storage service, even though FERC previously authorized the use of that storage facility for Section 311 interstate
service.

Natural
Gas
Gathering
and
Processing
Regulation

Section 1(b) of the NGA exempts natural gas gathering and processing facilities from the jurisdiction of the FERC. Although the FERC has not made formal
determinations  with respect to all of our facilities  we consider to be gathering facilities,  management believes that our natural gas gathering pipelines meet the
traditional tests that the FERC has used to determine that a pipeline is a gathering pipeline and is therefore not subject to FERC’s NGA jurisdiction. The distinction
between FERC-regulated transmission services and federally unregulated gathering services, however, has been the subject of substantial litigation, and the FERC
determines  whether  facilities  are  gathering  facilities  on  a  case-by-case  basis,  so  the  classification  and  regulation  of  our  gathering  facilities  is  subject  to  change
based on future determinations by the FERC, the courts or Congress. If the FERC were to consider the status of an individual facility and determine that the facility
and/or services provided by it are not exempt from FERC regulation under the NGA and that the facility provides interstate service, the rates for, and terms and
conditions  of,  services  provided  by  such  facility  would  be  subject  to  regulation  by  the  FERC  under  the  NGA  or  the  NGPA.  Such  regulation  could  decrease
revenue, increase operating costs, and, depending upon the facility in question, could adversely affect our results of operations and cash flows. In addition, if any of
our facilities were found to have provided services or otherwise operated in violation of the NGA or NGPA, this could result in the imposition of civil penalties as
well as a requirement to disgorge charges collected for such service in excess of the rate established by the FERC.

Table of Contents

States may regulate gathering pipelines. State regulation of gathering facilities generally includes various safety, environmental and, in some circumstances,
requirements prohibiting undue discrimination, and in some instances complaint-based rate regulation. Our gathering operations may be subject to ratable take and
common purchaser statutes in the states in which they operate. The ratable take statutes generally require gatherers to take, without undue discrimination, natural
gas  production  that  may  be  tendered  to  the  gatherer  for  handling.  Similarly,  common  purchaser  statutes  generally  require  gatherers  to  purchase  without  undue
discrimination as to source of supply or producer. These statutes are designed to prohibit discrimination in favor of one producer over another producer or one
source of supply over another source of supply. These statutes have the effect of restricting our right as an owner of gathering facilities to decide with whom we
contract to purchase or transport natural gas.

Our gathering operations could be adversely affected should they be subject in the future to the application of state or federal regulation of rates and services.
Our gathering operations could also be subject to additional safety and operational regulations relating to the design, construction, testing, operation, replacement
and maintenance of gathering facilities. Additional rules and legislation pertaining to these matters are considered or adopted from time to time. We cannot predict
what  effect,  if  any,  such  changes  might  have  on  its  operations,  but  the  industry  could  be  required  to  incur  additional  capital  expenditures  and  increased  costs
depending on future legislative and regulatory changes.

Sales
of
Natural
Gas

The price at which we buy and sell natural gas currently is not subject to federal regulation and, for the most part, is not subject to state regulation. However,
as noted above, with regard to our physical purchases and sales of these energy commodities, and any related hedging activities that we undertake, we are required
to observe anti-market manipulation laws and related regulations enforced by FERC and/or the CFTC. Should we violate the anti-market manipulation laws and
regulations, we could also be subject to related third-party damage claims by, among others, market participants, sellers, royalty owners and taxing authorities.

Our sales of natural gas are affected by the availability, terms and cost of pipeline transportation. As noted above, the price and terms of access to pipeline
transportation  are  subject  to  extensive  federal  and  state  regulation.  FERC  is  continually  proposing  and  implementing  new  rules  and  regulations  affecting  those
segments of the natural gas industry, most notably interstate natural gas transmission companies that remain subject to FERC jurisdiction. These initiatives also
may  affect  the  intrastate  transportation  of  natural  gas  under  certain  circumstances.  The  stated  purpose  of  many  of  these  regulatory  changes  is  to  promote
competition among the various sectors of the natural gas industry. We cannot predict the ultimate impact of these regulatory changes on our natural gas marketing
operations.

Interstate
Crude
Oil
Gathering
Regulation

Crude  oil  gathering  pipelines  that  transport  crude  oil  in  interstate  commerce  may  be  regulated  as  common  carriers  by  FERC  under  the  ICA,  the  Energy
Policy  Act  of  1992  and  the  rules  and  regulations  promulgated  under  those  laws.  Our  crude  oil  gathering  systems  in  the  Williston  Basin  transport  crude  oil  in
interstate  commerce.  The  ICA  and  FERC  regulations  require  that  rates  for  interstate  service  pipelines  that  transport  crude  oil  and  refined  petroleum  products
(collectively  referred  to  as  “petroleum  pipelines”)  and  certain  other  liquids,  be  just  and  reasonable  and  are  to  be  non-discriminatory  or  not  confer  any  undue
preference upon any shipper. FERC regulations also require interstate common carrier petroleum pipelines to file with FERC and publicly post tariffs stating their
interstate transportation rates and terms and conditions of service. Under the ICA, FERC or interested persons may challenge existing or changed rates or services.
The FERC is authorized to investigate such charges and may suspend the effectiveness of a new rate for up to seven months. A successful rate challenge could
result in a common carrier paying refunds together with interest for the period that the rate was in effect. FERC may also order a pipeline to change its rates and
may require a common carrier to pay shippers reparations for damages sustained for a period up to two years prior to the filing of a complaint.

If our rate levels were investigated by FERC, the inquiry could result in a comparison of our rates to those charged by others or to an investigation of our

costs, including:

•

•

•

•

•

•

•

the overall cost of service, including operating costs and overhead;

the allocation of overhead and other administrative and general expenses to the regulated entity;

the appropriate capital structure to be utilized in calculating rates;

the appropriate rate of return on equity and interest rates on debt;

the rate base, including the proper starting rate base;

the throughput underlying the rate; and

the proper allowance for federal and state income taxes.

For  some  time  now,  FERC  has  been  issuing  regulatory  assurances  that  necessarily  balance  the  anti-discrimination  and  undue  preference  requirements  of
common carriage with the expectations of investors in new and expanding petroleum pipelines. There is an inherent tension between the requirements imposed
upon  a  common  carrier  and  the  need  for  owners  of  petroleum  pipelines  to  be  able  to  enter  into  long-term,  firm  contracts  with  shippers  willing  to  make  the
commitments which underpin such large capital investments. For example, FERC has found that shipper contract rates are not per se violations of the duty of non-
discrimination, provided that such rates are available to all similarly-situated shippers. In the same vein, FERC has approved varying term commitments with tiered
rate discounts on the basis that committed shippers were not similarly situated with uncommitted shippers and further that different types of committed shippers
were not similarly situated with each other if their commitment level materially differed. FERC has also found that shippers making certain capacity commitments
to  the  pipeline  can  take  advantage  of  priority  or  firm  service,  which  is  service  that  is  not  subject  to  typical  capacity  allocation  requirements,  so  long  as  any
interested shipper has an equal opportunity to make such a commitment to the carrier. FERC’s solution has been to allow carriers to hold an “open season” prior to
the in-service date of a pipeline, during which time interested shippers can make commitments to the proposed pipeline project. Throughput commitments from
interested shippers during an open season can be for firm service or for non-firm service. Typically, such an open season is for a 30-day period, must be publicly
announced, and culminates in interested parties entering into transportation agreements with the carrier. Under FERC precedent, a carrier typically may reserve up
to 90% of available capacity for the provision of firm or priority service to shippers making a commitment. At least 10% of capacity ordinarily is reserved for
uncommitted shippers, i.e., “walk-up” shippers.

Under the ICA, FERC does not have authority over the siting of oil transportation assets nor over the abandonment of facilities or services. Accordingly, no
approval from FERC is necessary prior to placing a new petroleum pipeline project in operation. However, FERC highly encourages carriers to file a Petition for
Declaratory Order to seek regulatory assurances for key terms of service offered during an open season. As long as the shippers on our Bakken crude oil gathering
system move oil in interstate commerce, our crude oil gathering system will not be regulated by the North Dakota Public Service Commission.

FERC utilizes an indexing rate methodology which, as currently in effect, allows common carriers to change their rates within prescribed ceiling levels that
are  tied  to  changes  in  the  Producer  Price  Index.  The  indexing  methodology  is  applicable  to  existing  rates,  with  the  exclusion  of  market-based  rates.  FERC’s
indexing methodology is subject to review every five years. During the five-year period commencing July 1, 2016 and ending June 30, 2021, common carriers
charging  indexed  rates  are  permitted  to  adjust  their  indexed  ceilings  annually  by  the  Producer  Price  Index  plus  1.23%.  Many  existing  pipelines,  including  our
Williston  Basin  crude  oil  gathering  systems,  utilize  the  FERC  oil  index  to  change  transportation  rates  annually  every  July  1.  With  respect  to  oil  and  refined
products pipelines subject to FERC jurisdiction, the Revised Policy Statement requires the pipeline to reflect the impacts to its cost of service from the Revised
Policy Statement and the Tax Cuts and Jobs Act on the Page 700 of FERC Form No. 6. This information will be used by FERC in its next five-year review of the
oil pipeline index to generate the index level to be effective July 1, 2021, thereby including the effect of the Revised Policy Statement and the Tax Cuts and Jobs
Act in the determination of indexed rates prospectively, effective July 1, 2021. FERC’s establishment of a just and reasonable rate, including the determination of
the appropriate oil pipeline index, is based on many components, and tax-related changes will affect two such components, the allowance for income taxes and the
amount  for  ADIT,  while  other  pipeline  costs  also  will  continue  to  affect  FERC’s  determination  of  the  appropriate  pipeline  index.  Accordingly,  depending  on
FERC’s application of its indexing rate methodology for the next five-year term of index rates, the Revised Policy Statement and tax effects related to the Tax Cuts
and Jobs Act may impact our revenues associated with any transportation services we may provide pursuant to cost-of-service based rates, including indexed rates,
beginning July 1, 2021.

Intrastate
Crude
Oil
and
Condensate
Gathering
Regulation

Our crude oil and condensate gathering system in the Anadarko Basin is located in Oklahoma and is subject to limited regulation by the OCC. Crude oil and
condensate gathering systems are common carriers under Oklahoma law and are prohibited from unjust or unlawful discrimination in favor of one customer over
another. Additional rules and legislation pertaining to these matters are considered or adopted from time to time. Our crude oil and condensate gathering operations
could be adversely affected should they be subject in the future to the application of state or federal regulation of rates and services.

Safety and Health Regulation

Pipeline
Safety

Our pipeline facilities are subject to regulation under federal pipeline safety statutes and comparable state statutes. Federal pipeline safety statutes include the
Natural Gas Pipeline Safety Act of 1968 (NGPSA), which provides for safety requirements in the design, construction, operation and maintenance of natural gas
pipeline facilities, and the Hazardous Liquid Pipeline Safety

25

 
Table of Contents

Act of 1979 (HLPSA), which provides for safety requirements  for the design, construction, operation and maintenance of hazardous liquids pipelines facilities,
including NGL and crude oil pipelines. The NGPSA and the HLPSA have been subject to a number of amendments and supplements including the Pipeline Safety
Act  of  1992,  the  Accountable  Pipeline  Safety  and  Partnership  Act  of  1996,  the  Pipeline  Safety  Improvement  Act  of  2002,  the  Pipeline  Inspection,  Protection,
Enforcement and Safety Act of 2006 (the PIPES Act), the Pipeline Safety, Regulatory Certainty, Job Creation Act of 2011 (the 2011 Pipeline Safety Act), and the
Securing America’s Future Energy Protecting our Infrastructure of Pipelines and Enhancing Safety Act.

We are regulated under federal pipeline safety statutes by DOT through the Pipeline and Hazardous Materials Safety Administration (PHMSA). PHMSA sets
and  enforces  pipeline  safety  regulations  and  standards.  PHMSA’s  enforcement  authority  includes  the  ability  to  assess  civil  penalties  for  violations  of  pipeline
safety regulations. PHMSA has civil penalty authority of up to $209,002 per day per violation, with a maximum of $2,090,022 million for any related series of
violations.  In  addition  to  governing  the  design,  construction,  operation  and  maintenance  of  natural  gas  and  hazardous  liquids  pipeline  facilities,  PHMSA’s
regulations require the following for certain pipelines: an inspection and maintenance plan; an integrity management program, which includes the determination of
pipeline  integrity  risks and  periodic  assessments  of pipeline  segments  in high  consequence  areas;  a drug and alcohol  testing  program;  an operator  qualification
program,  which  includes  training  for  personnel  performing  tasks  covered  by  pipeline  safety  rules;  a  public  awareness  program,  which  provides  relevant
information to residents, public officials and emergency responders; and a control room management plan.

As part of regulating pipeline safety, PHMSA periodically promulgates pipeline safety regulations. For example, in December 2016, PHMSA published an
interim final rule providing pipeline safety regulations for underground natural gas storage. PHMSA also periodically publishes advisory bulletins. For example, in
January 2011, PHMSA published an advisory bulletin stating that operators of natural gas and hazardous liquid pipeline facilities should perform detailed threat
and risk analyses that integrate accurate data and information from their entire pipeline system and to utilize these risk analyses in the identification of appropriate
assessment methods and preventive and mitigative measures and, in May 2012, PHMSA published an advisory bulletin stating that operators of gas and hazardous
liquid  pipeline  facilities  should  verify  records  relating  to  operating  specifications  for  maximum  allowable  operating  pressure  (MAOP)  for  gas  pipelines  and
maximum operating pressure (MOP) for hazardous liquid pipelines. PHMSA has implemented an enhanced inspection program related to these new standards, and
PHMSA has announced that it intends to issue a final rule in 2019 that may impose additional requirements.

Federal pipeline safety regulations contain an exemption that applies to gathering lines in certain rural locations. A substantial portion of our gathering lines
qualify for that exemption and are currently not regulated under federal law. However, in May 2016, PHMSA proposed rules that would, if adopted, impose more
stringent requirements for certain gas lines. Among other things, the proposed rulemaking would extend certain of PHMSA’s current regulatory safety programs
for  gas  pipelines  beyond  “high  consequence  areas”  to  cover  gas  pipelines  found  in  newly  defined  “moderate  consequence  areas”  that  contain  as  few  as  five
dwellings  within  the  potential  impact  area  and  would  also  require  gas  pipelines  installed  before  1970  that  are  currently  exempted  from  certain  pressure  testing
obligations  to  be  tested  to  determine  their  maximum  allowable  operating  pressures  (MAOP).  Other  new  requirements  proposed  by  PHMSA  under  rulemaking
would  require  pipeline  operators  to:  report  to  PHMSA  in  the  event  of  certain  MAOP  exceedances;  strengthen  PHMSA  integrity  management  requirements;
consider seismicity in evaluating threats to a pipeline; conduct hydrostatic testing for all pipeline segments manufactured using longitudinal seam welds; and use
more  detailed  guidance  from  PHMSA in the  selection  of  assessment  methods  to  inspect  pipelines.  The  proposed  rulemaking  also seeks  to  impose  a number  of
requirements  on  natural  gas  gathering  lines.  PHMSA  has  announced  its  intention  to  divide  the  proposed  rule  into  three  parts  and  issue  three  separate  final
rulemakings in 2019. Part I is expected to address the expansion of risk assessment and MAOP requirements (expected issuance in March 2019); Part II is expected
to address the expansion of integrity management program regulations (expected issuance in June 2019); and Part III is expected to expand the regulation of gas
gathering  lines  (expected  issuance  in  August  2019).  We  cannot  predict  whether  PHMSA  will  meet  these  deadlines  or  what  form  these  final  rules  may  take.
Separately,  in  January  2017,  PHMSA  finalized  regulations  for  hazardous  liquid  pipelines  that  significantly  extend  and  expand  the  reach  of  certain  PHMSA
integrity management requirements (i.e., periodic assessments, leak detection and repairs), regardless of the pipeline’s proximity to a high consequence area. The
final rule would also impose new reporting requirements for certain unregulated pipelines, including all hazardous liquid gathering lines. However, implementation
of this rule has been delayed as a result of the change in presidential administrations, and the final rule is not expected to be published by the Federal Register until
some time in the first half of 2019.

States are largely preempted by federal law from regulating pipeline safety but may assume responsibility for administering and enforcing intrastate pipeline
regulations  at  least  as  stringent  as  the  federal  standards.  For  example,  the  OCC  administers  the  intrastate  pipeline  safety  program  in  Oklahoma,  and  the  Texas
Railroad Commission administers the intrastate pipeline safety program in Texas. In practice, states vary in their authority and capacity to address pipeline safety.

We incur significant costs in complying with federal and state pipeline safety laws and regulations and otherwise administering our pipeline safety program.

In 2018 , we incurred maintenance capital expenditures and operation and maintenance expenses of

26

 
Table of Contents

$54 million under our pipeline safety program, including costs related to integrity assessments and repairs, threat and risk analyses, implementing preventative and
mitigative measures, and conducting activities to support MAOP or MOP. We currently estimate that we will incur maintenance capital expenditures and operation
and  maintenance  expenses  of  up  to  $65  million  in  2019  under  our  pipeline  safety  program.  While  we  cannot  predict  the  outcome  of  legislative  or  regulatory
initiatives, we anticipate that pipeline safety requirements will continue to become more stringent over time. As a result, we may incur significant additional costs
to comply with any new pipeline safety laws and regulations associated with our pipeline facilities.

Occupational
Health
and
Safety

In addition to these pipeline safety requirements, we are subject to a number of federal and state laws and regulations, including the Occupational Safety and
Health Act of 1970 (OSHA) and comparable state statutes, whose purpose is to protect the safety and health of workers, both generally and within the pipeline
industry.  In  addition,  the  OSHA  hazard  communication  standard,  the  EPA  community  right-to-know  regulations  under  Title  III  of  the  Federal  Superfund
Amendment and Reauthorization Act and comparable state statutes require that information be maintained concerning hazardous materials used or produced in our
operations and that this information be provided to employees, state and local government authorities and citizens. We are also subject to OSHA Process Safety
Management  regulations,  which  are  designed  to  prevent  or  minimize  the  consequences  of  catastrophic  releases  of  toxic,  reactive,  flammable  or  explosive
chemicals. These regulations apply to any process which involves a chemical at or above the specified thresholds or any process which involves flammable liquid
or gas, pressurized tanks, caverns and wells in excess of 10,000 pounds at various locations. We have an internal program of inspection designed to monitor and
enforce  compliance  with  worker  safety  and  health  requirements.  We  are  also  subject  to  EPA  Risk  Management  Program  (RMP)  regulations.  In  2017,  EPA
published a final rule to amend the Accidental Release Prevention Requirements for RMPs. However, this has been subject to both attempted regulatory rollback
and litigation. The final status of these rules remains uncertain.

Physical
Security

The Department of Homeland Security Appropriation Act of 2007 requires the Department of Homeland Security (DHS) to issue regulations establishing
risk-based performance standards for the security of chemical and industrial facilities, including oil and gas facilities that are deemed to present “high levels of
security  risk.”  The  DHS  issued  an  interim  final  rule  in  April  2007  regarding  risk-based  performance  standards  to  be  attained  pursuant  to  this  act  and,  on
November 20, 2007, further issued an Appendix A to the interim rules that establish chemicals of interest and their respective threshold quantities that will trigger
compliance with these interim rules. Covered facilities  that are determined by DHS to pose a high level of security risk will be required to prepare and submit
Security Vulnerability Assessments and Site Security Plans as well as comply with other regulatory requirements, including those regarding inspections, audits,
recordkeeping, and protection of chemical-terrorism vulnerability information. Congress reauthorized this program in January 2019, and both Congress and DHS
have indicated that they intend to propose revisions to the program’s implementation. We cannot predict what action, if any, Congress or DHS may take at this
time.

Cybersecurity

We have become increasingly dependent on the systems, networks and technology that we use to conduct almost all aspects of our business, including the
operation of our gathering, processing, transportation and storage assets, the recording of commercial transactions, and the reporting of financial information. We
depend on both our own systems, networks, and technology as well as the systems, networks and technology of our vendors, customers and other business partners.
We  have  existing,  and  continue  to  develop,  systems  in  place  to  monitor  and  address  the  risk  of  cybersecurity  breaches  in  our  business,  operations  and  control
environments. We routinely review and update those systems as the nature of that risk requires. Although we have not experienced any cybersecurity incidents that
have significantly impacted any of our business, operations or control environments, a significant cybersecurity incident could have a material effect on our results
of operations.

Environmental Regulation

General

Our operations  are subject to extensive  federal, state and local environmental  laws and regulations. These laws and regulations can restrict or impact our
business activities in many ways, such as requiring permits to conduct our activities, limiting our emissions of materials into the environment, requiring emissions
control  equipment,  regulating  our  construction  to  mitigate  harm  to  protected  species,  restricting  the  way  we  can  handle  or  dispose  of  waste,  and  requiring
remediation  to  mitigate  the  impact  of  materials  discharged  into  the  environment  in  connection  with  our  current  operations  or  attributable  to  former  operation.
Compliance with these laws and regulations increases our capital expenditures and operating expenses, and any failure to comply with these laws

27

 
 
 
 
 
Table of Contents

and regulations could result in the assessment of significant administrative, civil and criminal liabilities, injunctions or other penalties.

We have adopted policies, procedures, and practices to comply with environmental laws and regulations, and we incur significant costs in connection with
compliance.  In  2018  ,  we  incurred  approximately  $1  million  in  maintenance  capital  expenditures  in  connection  with  routine  environmental  compliance  with
existing  laws  and  regulations,  such  as  environmental  controls,  monitoring,  testing  and  permit  compliance.  We  expect  to  incur  expenditures  for  routine
environmental compliance with existing laws and regulations of $2 million in 2019 . We also incur, and expect to continue to incur, additional costs in connection
with  spill  response  and construction.  With  respect  to  construction,  existing  environmental  laws and  regulations  impact  the  cost of  planning,  design,  permitting,
installation, and start-up. While we cannot predict the outcome of legislative or regulatory initiatives, we anticipate that environmental requirements will continue
to become more restrictive over time. As a result, we may incur significant additional costs to comply with any new environmental laws and regulations applicable
to our operations. For more information, please read Item 1A. “Risk Factors–Costs of compliance with existing environmental laws and regulations are significant,
and the cost of compliance with future environmental laws and regulations may adversely affect our financial position, results of operations and ability to make
cash distributions to unitholders.”

Air

Our operations are subject to the federal Clean Air Act (CAA), as amended, and comparable state laws and regulations. These laws and regulations regulate
emissions of air pollutants from various industrial sources, including natural gas processing plants and compressor stations, and impose various monitoring and
reporting  requirements.  Such  laws  and  regulations  may  require  that  we  obtain  pre-approval  for  the  construction  or  modification  of  certain  projects  or  facilities
expected to produce air emissions or result in the increase of existing air emissions (including greenhouse gas emissions as discussed below), obtain and strictly
comply with air permits containing various emissions and operational limitations or install emission control equipment. For example, in October 2015, the EPA
lowered  the  National  Ambient  Air  Quality  Standard  (NAAQS) for  ozone  from  75  to  70  parts  per  billion,  and  the  agency  completed  attainment/non-attainment
designations in July 2018. Some of our facilities are located in designated non-attainment areas. State implementation of the revised NAAQS could result in stricter
permitting requirements, delay or prohibit our ability to obtain such permits and result in increased expenditures for pollution control equipment, the costs of which
could be significant. We likely will be required to incur certain capital expenditures in the future for air pollution control equipment and technology in connection
with obtaining and maintaining operating permits and approvals for air emissions.

Climate
Change

There has been a wide-ranging policy debate, both nationally and internationally, regarding climate change, greenhouse gas (GHG) emissions, and possible
means for the regulation of GHG emissions. Examples of GHGs include methane, which is a primary component of natural gas, and carbon dioxide, which is a
byproduct of the combustion of natural gas as well as the treatment of raw gas before it is delivered to pipelines in a merchantable state of quality. Various laws
and regulations exist or are under development to regulate the emission of GHGs, including EPA programs to control GHGs and state actions to develop statewide
or regional programs to control GHGs. In addition, the United States Congress has, from time to time, considered adopting legislation to reduce GHG emissions.

The EPA has published findings that certain GHGs may endanger human health, and the EPA has adopted regulations requiring the reporting and permitting
of GHG emissions under the CAA. Our operations are subject to those regulations. Those regulations require monitoring and annual reporting of GHG emissions
from  certain  petroleum  and  natural  gas  system  sources  in  the  U.S.,  including,  among  others,  gathering  and  processing  facilities  which  include  certain  of  our
operations, and the permitting of large stationary sources of GHG under the CAA’s Prevention of Significant Deterioration and Title V programs. Moreover, in
June  2016,  the  EPA  published  New  Source  Performance  Standards  (NSPS),  known  as  Subpart  OOOOa,  that  requires  certain  new,  modified  or  reconstructed
facilities in the oil and natural gas sector to reduce these methane gas and volatile organic compound emissions through a combination of emission control devices
and implementation of enhanced leak detection and repair practices. Following the change in presidential administrations, there have been attempts to modify these
regulations, and litigation concerning the regulations is ongoing. As a result, we cannot predict the scope of any final methane regulatory requirements or the cost
to comply with such requirements. However, given the historical trend towards stricter regulation of GHG emissions, it is possible that new federal methane rules
may be proposed or finalized in the future.

Several states have adopted laws and regulations intended to reduce the emission of GHGs, including through the planned development of GHG emission
inventories and/or regional GHG cap and trade programs. The states where our operations are currently located (Alabama, Arkansas, Illinois, Kansas, Louisiana,
Mississippi, Missouri, Oklahoma, North Dakota, Tennessee, and Texas) are not among them; however, they may choose to promulgate such rules in the future.

While we cannot predict the outcome of legislative or regulatory initiatives, we anticipate that initiatives to reduce GHG emissions will continue to develop.
The adoption of state or federal legislation or regulatory programs to reduce emissions of GHGs, including methane and carbon dioxide, could require us to incur
increased operating costs, such as costs to purchase and operate emissions monitoring and control systems, to acquire emissions allowances or comply with new
regulatory or reporting requirements. Any such legislation or regulatory programs could also increase the cost of consuming natural gas and other hydrocarbons,
and thereby reduce demand for, the natural gas we gather, treat and transport. Consequently, legislation and regulatory programs to reduce emissions of GHGs
could  have  an  adverse  effect  on  our  business,  financial  condition  and  results  of  operations.  Notwithstanding  potential  risks  related  to  climate  change,  the
International Energy Agency estimates that oil and gas will continue to represent a major share of global energy use through 2040, and other private sector studies
project  continued growth in demand for the next two decades. However, recent activism  directed  at shifting funding away from companies with energy-related
assets could result in limitations or restrictions on certain sources of funding for the energy sector.

National
Environmental
Policy
Act
(NEPA)

NEPA provides for an environmental impact assessment process in connection with certain projects that involve federal lands or require approvals by federal
agencies. The NEPA process implicates a number of other environmental laws and regulations, including the Endangered Species Act, Migratory Bird Treaty Act,
Rivers  and  Harbors  Act,  Clean  Water  Act,  Bald  and  Golden  Eagle  Protection  Act,  Fish  and  Wildlife  Coordination  Act,  Marine  Mammal  Protection  Act  and
National Historic Preservation Act. The NEPA review process can be lengthy and subjective and can cause delays in projects. Our projects that are subject to the
NEPA  can  include  pipeline  construction  and  pipeline  integrity  projects  that  involve  federal  lands  or  require  approvals  by  federal  agencies.  Ineffective
implementation of the NEPA process could cause significant impacts to such projects in the form of delays or significant compliance costs.

Protected
Species

Certain federal laws, including the Bald and Golden Eagle Protection Act, the Migratory Bird Treaty Act and the Endangered Species Act, provide special
protection  to  certain  designated  species.  These  laws  and  any  state  equivalents  provide  for  significant  civil  and  criminal  penalties  for  unpermitted  activities  that
result  in  harm  to  or  harassment  of  certain  protected  animals  and  plants,  including  damage  to  their  habitats.  If  such  species  are  located  in  an  area  in  which  we
conduct operations, or if additional species in those areas become subject to protection, our operations and development projects, particularly  pipeline projects,
could be restricted or delayed, or we could be required to implement expensive mitigation measures. The designation of previously unprotected species, such as the
Lesser  Prairie  Chicken,  as  threatened  or  endangered  in  areas  where  our  operations  are  conducted  could  cause  us  to  incur  increased  costs  arising  from  species
protection measures or could result in limitations on our customer’s exploration and production activities that could have an adverse impact on demand for our
services. Portions of the basins we serve are designated as critical or suitable habitat for threatened and endangered species. If additional portions of the basins we
serve  were  designated  as  critical  or  suitable  habitat  for  threatened  and  endangered  species,  it  could  adversely  impact  the  cost  of  operating  our  systems  and  of
constructing new facilities. Management believes that we are in material compliance with all applicable laws providing special protection to designated species.

Hazardous
Substances
and
Waste

Our operations are subject to federal and state environmental laws and regulations relating to the management and release of hazardous substances, solid and
hazardous  wastes,  and  petroleum  hydrocarbons.  For  instance,  our  operations  are  subject  to  the  Comprehensive  Environmental  Response,  Compensation  and
Liability Act of 1980 (CERCLA or Superfund), as amended, and comparable state cleanup laws that impose liability, without regard to the legality of the original
conduct, on certain classes of persons responsible for the release of hazardous substances into the environment. These persons include current and prior owners or
operators  of  the  site  where  the  release  occurred  and  companies  that  disposed  or  arranged  for  the  disposal  of  the  hazardous  substances  found  at  the  site.  Under
CERCLA, these persons may, jointly and severally, be subject to strict liability for the costs of cleaning up the hazardous substances that have been released into
the environment, for damages to natural resources and for the costs of certain health studies. CERCLA also authorizes the EPA and, in some instances, third parties
to act in response to threats to the public health or the environment and to seek to recover the costs they incur from the responsible classes of persons. It is not
uncommon for neighboring landowners and other third parties to file claims for personal injury and property damage allegedly caused by hazardous substances or
other pollutants released into the environment. Because we utilize various products and generate wastes that are considered hazardous substances for purposes of
CERCLA, we could be subject to liability for the costs of cleaning up and restoring sites where those substances have been released to the environment.

Our operations also generate solid and hazardous wastes that are subject to the federal Resource Conservation and Recovery Act of 1976 (RCRA) as well as
comparable state laws. While RCRA regulates both solid and hazardous wastes, it imposes detailed requirements for the handling, storage, treatment and disposal
of hazardous waste. RCRA currently exempts many natural gas

29

 
 
 
 
 
 
 
Table of Contents

gathering  and  field  processing  wastes  from  classification  as  hazardous  waste.  However,  it  is  possible  that  these  wastes,  which  could  include  wastes  currently
generated during our operations, will in the future be designated as “hazardous wastes” and therefore be subject to more rigorous and costly disposal requirements.
Such changes to the law could have an impact on our capital expenditures and operating expenses. For example, in December 2016, the EPA and environmental
groups entered into a consent decree to address the EPA’s alleged failure to timely assess its RCRA Subtitle D criteria regulations exempting certain exploration
and  production  related  oil,  natural  gas  and  NGL  wastes  from  regulation  as  hazardous  wastes  under  RCRA.  The  consent  decree  requires  the  EPA  to  propose  a
rulemaking  no  later  than  March  15,  2019  for  revision  of  certain  Subtitle  D  criteria  regulations  pertaining  to  oil,  natural  gas  and  NGL  wastes  or  to  sign  a
determination that revision of the regulations is not necessary. We cannot predict whether the EPA will meet this deadline. If the EPA proposes rulemaking for
revised oil and natural gas regulations, the consent decree requires that the EPA take final action following notice and comment rulemaking no later than July 15,
2021.  Any  such  change  could  result  in  an  increase  in  the  costs  to  manage  and  dispose  of  wastes,  which  could  increase  the  costs  of  our  operators’  operations.
Further, these currently RCRA-exempt oil and gas exploration and production wastes may still be regulated under state law or RCRA’s less stringent solid waste
requirements. The transportation of natural gas in pipelines may also generate some hazardous wastes that are subject to RCRA or a comparable state law regime.

Water

Our  operations  are  subject  to  the  federal  Clean  Water  Act  (CWA)  and  analogous  state  laws  and  regulations.  These  laws  and  regulations  impose  detailed
requirements and strict controls regarding the discharge of pollutants into state and federal waters. The discharge of pollutants, including discharges resulting from
a spill or leak, is prohibited unless authorized by a permit or other agency approval. In addition, the CWA and analogous state laws require individual permits or
coverage under general permits for discharges of storm water runoff from certain types of facilities. These permits may require us to monitor and sample the storm
water runoff from some of our facilities. The CWA and regulations implemented thereunder also prohibit discharges of dredged and fill material in wetlands and
other waters of the United States unless authorized by an appropriately  issued permit.  In June 2015, the EPA and United States Army Corps of Engineers  (the
“Corps”)  published  a  final  rule  attempting  to  clarify  the  federal  jurisdictional  reach  over  WOTUS.  Several  legal  challenges  to  the  rule  followed,  along  with
attempts to stay implementation following the change in presidential administrations. Currently, the WOTUS rule is active in 22 states and enjoined in 28 states.
However,  in  December  2018,  the  EPA  and  the  Corps  proposed  changes  to  regulations  under  the  CWA  that  would  provide  discrete  categories  of  jurisdictional
waters  and  tests  for  determining  whether  a  particular  waterbody  meets  any  of  those  classifications.  Several  groups  have  already  announced  their  intentions  to
challenge the proposed WOTUS replacement rule. Therefore, the scope of jurisdiction under the CWA is uncertain at this time. Separately, spill prevention, control
and  countermeasure  requirements  of  federal  laws  require  appropriate  containment  berms  and  similar  structures  to  help  prevent  the  contamination  of  regulated
waters in the event of a hydrocarbon tank spill, rupture or leak. Federal and state regulatory agencies can impose administrative, civil and criminal penalties for
non-compliance with many of these requirements.

Certain of our operations are also subject to the Oil Pollution Act (the OPA) which amends and augments oil spill provisions of the Clean Water Act and
imposes certain duties and liabilities on certain “responsible parties” related to the prevention of oil spills and damages resulting from such spills in or threatening
United States waters or adjoining shorelines. A liable “responsible party” includes the owner or operator of a facility, vessel or pipeline that is a source of an oil
discharge or that poses the substantial threat of discharge, or in the case of offshore facilities, the lessee or permittee of the area in which a discharging facility is
located.  Under  OPA,  joint  and  several  liability,  without  regard  to  fault,  may  be  assigned  for  oil  removal  costs  and  a  variety  of  public  and  private  damages.
Although defenses exist to the liability imposed by OPA, they are limited. In the event of an oil discharge or substantial threat of discharge, we may be liable for
costs and damages.

Hydraulic
Fracturing

Hydraulic fracturing is an important and common practice that is used to stimulate production of hydrocarbons from tight formations. The process involves
the injection of water, sand and chemicals under pressure into the formation to fracture the surrounding rock and stimulate production. The process is regulated by
state agencies, typically the state’s commission that regulates oil and gas production. A number of federal agencies, including the EPA and the U.S. Department of
Energy, have analyzed, or have been requested to review, a variety of environmental issues associated with hydraulic fracturing. For example, the EPA finalized
regulations under the CWA in June 2016 prohibiting wastewater discharges from hydraulic fracturing and certain other natural gas operations to publicly owned
wastewater  treatment  plants.  In  addition,  some  states  have  adopted,  and  other  states  are  considering  adopting,  regulations  that  could  impose  more  stringent
disclosure and/or well construction requirements on hydraulic fracturing operations.

State and federal regulatory agencies also recently focused on a possible connection between the operation of injection wells used for oil and gas wastewater
disposal and seismic activity. Similar concerns have been raised that hydraulic fracturing may also contribute to seismic activity. When caused by human activity,
such events are called induced seismicity. In March 2016, the

30

 
 
Table of Contents

United  States  Geological  Survey  identified  six  states  with  the  most  significant  hazards  from  induced  seismicity:  Oklahoma,  Kansas,  Texas,  Colorado,  New
Mexico, and Arkansas. In light of these concerns, some state regulatory agencies have modified their regulations or issued orders to address induced seismicity
through restrictions on disposal wells or enhanced well construction and monitoring requirements. Certain environmental and other groups have also suggested that
additional federal, state and local laws and regulations may be needed to more closely regulate the wastewater disposal process.

If new laws or regulations that significantly restrict hydraulic fracturing or wastewater disposal wells are adopted, such laws could lead to greater opposition
to, and litigation concerning, related oil and gas producing activities and to operational delays or increased operating costs for our customers, which in turn could
reduce  the  demand  for  our  services.  For  more  information,  please  read  Item  1A.  “Risk  Factors–Increased  regulation  of  hydraulic  fracturing  and  waste  water
injection  wells  could  result  in  reductions  or  delays  in  natural  gas  production  by  our  customers,  which  could  adversely  affect  our  financial  position,  results  of
operations and ability to make cash distributions to unitholders.”

Our Employees

As of December 31, 2018 , we employ approximately 1,705 employees with an additional 89 individuals providing services to us as seconded employees of
OGE Energy. Personnel remain seconded to the Partnership, subject to certain termination rights of the Partnership and OGE Energy, in order to continue their
participation  in  OGE  Energy’s  defined  benefit  and  retiree  medical  plans.  Please  read  Item  13.  “Certain  Relationships  and  Related  Transactions,  and  Director
Independence—Employee Secondment” for a description of the agreements governing these relationships.

Item 1A. Risk Factors

You should carefully consider each of the following risks and all of the other information contained in this Annual Report on Form 10-K in evaluating us and
our  common  units.  Some  of  these  risks  relate  principally  to  our  business  and  the  industry  in  which  we  operate,  while  others  relate  principally  to  tax  matters,
ownership of our common units, our preferred units and securities markets generally. If any of the following risks were actually to occur, our business, financial
position  or  results  of  operations  could  be  materially  adversely  affected.  In  that  case,  we  might  not  be  able  to  pay  the  minimum  quarterly  distribution  on  our
common units, or the trading price of our common units could decline.

Risks Related to Our Business

We 
may 
not 
have 
sufficient 
cash 
from 
operations 
following 
the 
establishment 
of 
cash 
reserves 
and 
payment 
of 
fees 
and 
expenses, 
including 
cost
reimbursements
to
our
general
partner
and
its
affiliates,
to
enable
us
to
maintain
or
increase
the
distributions
to
holders
of
our
common
units.

We may not have sufficient available cash each quarter to enable us to maintain or increase the distributions to holders of our common units. The amount of
cash we can distribute on our units principally depends upon the amount of cash we generate from our operations, which will fluctuate from quarter to quarter
based on, among other things:

•

•

•

•

•

the fees and gross margins we realize with respect to the volume of natural gas, NGLs and crude oil that we handle;

the prices of, levels of production of, and demand for natural gas, NGLs and crude oil;

the volume of natural gas, NGLs and crude oil we gather, compress, treat, dehydrate, process, fractionate, transport and store;

the relationship among prices for natural gas, NGLs and crude oil;

cash calls and settlements of hedging positions;

• margin requirements on open price risk management assets and liabilities;

•

•

•

•

the level of competition from other companies offering midstream services;

adverse effects of governmental and environmental regulation;

the level of our operation and maintenance expenses and general and administrative costs; and

prevailing economic conditions.

In addition, the actual amount of cash we will have available for distribution will depend on other factors, including:

•

•

•

•

•

•

•

•

•

the level and timing of capital expenditures we make;

the cost of acquisitions;

our debt service requirements and other liabilities;

fluctuations in working capital needs;

our ability to borrow funds and access capital markets;

restrictions contained in our debt agreements;

the amount of cash reserves established by our general partner;

distributions paid on our Series A Preferred Units; and

other business risks affecting our cash levels.

Our
contracts
are
subject
to
renewal
risks.

As contracts with our existing suppliers and customers expire, we negotiate extensions or renewals of those contracts or enter into new contracts with other
suppliers and customers. We may be unable to extend or renew existing contracts or enter into new contracts on favorable commercial terms, if at all. Depending
on  prevailing  market  conditions  at  the  time  of  an  extension  or  renewal,  gathering  and  processing  customers  with  fee-based  contracts  may  desire  to  enter  into
contracts under different fee arrangements, and gathering and processing customers with contracts that contain minimum volume commitments may desire to enter
into contracts without minimum volume commitments. Likewise, our transportation and storage customers may choose not to extend or renew expiring contracts
based on the economics of the related areas of production. To the extent we are unable to renew or replace our expiring contracts on terms that are favorable to us,
if at all, or successfully manage our overall contract mix

32

 
 
 
 
Table of Contents

over time, our financial position, results of operations and ability to make cash distributions to unitholders could be adversely affected.

We
depend
on
a
small
number
of
customers
for
a
significant
portion
of
our
gathering
and
processing
revenues
and
our
transportation
and
storage
revenues.
The
loss
of,
or
reduction
in
volumes
from,
these
customers
could
result
in
a
decline
in
sales
of
our
gathering
and
processing
or
transportation
and
storage
services
and
adversely
affect
our
financial
position,
results
of
operations
and
ability
to
make
cash
distributions
to
our
unitholders.

For the year ended December 31, 2018 , 61% of our natural gas gathered volumes were attributable to the affiliates of Continental, Vine, GeoSouthern, XTO
and Tapstone and 51% of our transportation and storage service revenues were attributable to affiliates of CenterPoint Energy, Spire, Continental, AEP and OGE
Energy. The loss of all or even a portion of the gathering and processing or transportation and storage services for any of these customers, the failure to extend or
replace these contracts or the extension or replacement of these contracts on less favorable terms, as a result of competition or otherwise, could adversely affect our
financial position, results of operations and ability to make cash distributions to unitholders.

Our
businesses
are
dependent,
in
part,
on
the
drilling
and
production
decisions
of
others.

Our businesses are dependent on the drilling and production of natural gas and crude oil. We have no control over the level of drilling activity in our areas of
operation, or the amount of natural gas, NGL and crude oil reserves associated with wells connected to our systems. In addition, as the rate at which production
from wells currently connected to our system naturally declines over time, our gross margin associated with those wells will also decline. To maintain or increase
throughput levels on our gathering and transportation systems and the asset utilization rates at our natural gas processing plants, our customers must continually
obtain new natural gas, NGL and crude oil supplies. The primary factors affecting our ability to obtain new supplies of natural gas, NGLs and crude oil and attract
new customers to our assets are the level of successful drilling activity near our systems, our ability to compete for volumes from successful new wells and our
ability to expand our capacity as needed. If we are not able to obtain new supplies of natural gas, NGLs and crude oil to replace the natural decline in volumes from
existing  wells,  throughput  on our  gathering,  processing,  transportation  and  storage  facilities  would decline,  which  could  adversely  affect  our  financial  position,
results of operations and ability to make cash distributions to unitholders. We have no control over producers or their drilling and production decisions, which are
affected by, among other things: 

•

•

•

•

•

•

•

the availability and cost of capital;

prevailing and projected commodity prices, including the prices of natural gas, NGLs and crude oil;

demand for natural gas, NGLs and crude oil;

levels of reserves;

geological considerations;

environmental or other governmental regulations, including the availability of drilling permits, the regulation of hydraulic fracturing, and the regulation
of air emissions; and

the availability of drilling rigs and other costs of production and equipment.

Fluctuations  in  energy  prices  can  also  greatly  affect  the  development  of  new  natural  gas,  NGL  and  crude  oil  reserves.  Drilling  and  production  activity
generally  decreases  as  commodity  prices  decrease.  In  general  terms,  the  prices  of  natural  gas,  NGLs,  crude  oil  and  other  hydrocarbon  products  fluctuate  in
response to changes in supply and demand, market uncertainty and a variety of additional factors that are beyond our control. Because of these and other factors,
even if new reserves are known to exist in areas served by our assets, producers may choose not to develop those reserves. Declines in natural gas, NGL or crude
oil prices can have a negative impact on exploration, development and production activity and, if sustained, could lead to decreases in such activity. Sustained low
natural gas, NGL or crude oil prices could also lead producers to shut in production from their existing wells. Sustained reductions in exploration or production
activity in our areas of operation could lead to further reductions in the utilization of our systems, which could adversely affect our financial position, results of
operations and ability to make cash distributions to unitholders.

In addition, it may be more difficult to maintain or increase the current volumes on our gathering systems and in our processing plants, as several of the
formations in the unconventional resource plays in which we operate generally have higher initial production rates and steeper production decline curves than wells
in more conventional basins. Should we determine that the economics of our gathering assets do not justify the capital expenditures needed to grow or maintain
volumes associated therewith, we may reduce such capital expenditures, which could cause revenues associated with these assets to decline over time.

Our
industry
is
highly
competitive
and
increased
competitive
pressure
could
adversely
affect
our
financial
position,
results
of
operations
and
ability
to
make
cash
distributions
to
unitholders.

We compete with similar enterprises in our respective areas of operation. The principal elements of competition are rates, terms of service and flexibility and
reliability of service. Our competitors include large energy companies that have greater financial resources and access to supplies of natural gas, NGLs and crude
oil than us. Some of these competitors may expand or construct gathering, processing, transportation and storage systems that would create additional competition
for  the  services  we  provide  to  our  customers.  Excess  pipeline  capacity  in  the  regions  served  by  our  interstate  pipelines  could  also  increase  competition  and
adversely impact our ability to renew or enter into new contracts with respect to our available capacity when existing contracts expire. In addition, our customers
that are significant producers of natural gas or crude oil may develop their own gathering, processing, transportation and storage systems in lieu of using ours. Our
ability to renew or replace existing contracts with our customers at rates sufficient to maintain current revenues and cash flows could be adversely affected by the
activities of our competitors and customers. Further, natural gas utilized as a fuel competes with other forms of energy available to end-users, including electricity,
coal  and  liquid  fuels.  Increased  demand  for  such  forms  of  energy  at  the  expense  of  natural  gas  could  lead  to  a  reduction  in  demand  for  natural  gas  gathering,
processing, transportation and storage services. All of these competitive pressures could adversely affect our financial position, results of operations and ability to
make cash distributions to unitholders.

We
derive
a
substantial
portion
of
our
gross
margin
from
subsidiaries
through
which
we
hold
a
substantial
portion
of
our
assets.

We derive a substantial portion of our gross margin from, and hold a substantial portion of our assets through, our subsidiaries. As a result, we depend on
distributions  from  our  subsidiaries  in  order  to  meet  our  payment  obligations.  In  general,  these  subsidiaries  are  separate  and  distinct  legal  entities  and  have  no
obligation to provide us with funds for our payment obligations, whether by dividends, distributions, loans or otherwise. In addition, provisions of applicable law,
such as those limiting the legal sources of dividends, limit our subsidiaries’ ability to make payments or other distributions to us, and our subsidiaries could agree
to contractual restrictions on their ability to make distributions.

Our right to receive any assets of any subsidiary, and therefore the right of our creditors to participate in those assets, will be effectively subordinated to the
claims  of  that  subsidiary’s  creditors,  including  trade  creditors.  In  addition,  even  if  we  were  a  creditor  of  any  subsidiary,  our  rights  as  a  creditor  would  be
subordinated to any security interest in the assets of that subsidiary and any indebtedness of the subsidiary senior to that held by us.

The
amount
of
cash
we
have
available
for
distribution
to
our
limited
partners
depends
primarily
on
our
cash
flow
rather
than
on
our
profitability,
which
may
prevent
us
from
making
distributions,
even
during
periods
in
which
we
record
net
income.

The amount of cash we have available for distribution depends primarily upon our cash flow rather than on profitability. Profitability is affected by non-cash
items but cash flow is not. As a result, we may make cash distributions during periods when we record losses for financial accounting purposes and may not make
cash distributions during periods when we record net earnings for financial accounting purposes.

We
may
not
be
able
to
recover
the
costs
of
our
substantial
planned
investment
in
capital
improvements
and
additions,
and
the
actual
cost
of
such
improvements
and
additions
may
be
significantly
higher
than
we
anticipate.

Our business plan calls for investment in capital improvements and additions. For the year ending December 31, 2019, we estimate that expansion capital

could range from approximately $325 million to $425 million and our maintenance capital could range from approximately $105 million to $125 million.

The  construction  of  additions  or  modifications  to  our  existing  systems,  and  the  construction  of  new  midstream  assets,  involves  numerous  regulatory,
environmental, political and legal uncertainties, many of which are beyond our control and may require the expenditure of significant amounts of capital, which
may exceed our estimates. These projects may not be completed at the planned cost, on schedule or at all. The construction of new pipeline, gathering, treating,
processing, compression  or other facilities  is subject to construction  cost overruns  due to labor costs, costs and availability  of equipment  and materials  such as
steel,  labor  shortages  or  weather  or  other  delays,  inflation  or  other  factors,  which  could  be  material.  In  addition,  the  construction  of  these  facilities  is  typically
subject to the receipt of approvals and permits from various regulatory agencies. Those agencies may not approve the projects in a timely manner, if at all, or may
impose  restrictions  or  conditions  on  the  projects  that  could  potentially  prevent  a  project  from  proceeding,  lengthen  its  expected  completion  schedule  and/or
increase  its  anticipated  cost.  Moreover,  our  revenues  and  cash  flows  may  not  increase  immediately  upon  the  expenditure  of  funds  on  a  particular  project.  For
instance, if we expand an existing pipeline or construct a new pipeline, the construction may occur over an extended period of time, and we may not receive any
material increases in revenues or cash flows until the project is completed. In addition, we may construct facilities

34

 
 
 
 
 
 
 
 
Table of Contents

to capture anticipated future growth in production in a region in which such growth does not materialize. As a result, the new facilities may not be able to achieve
our expected investment return, which could adversely affect our financial position, results of operations and ability to make cash distributions to unitholders.

In  connection  with  our  capital  investments,  we  may  estimate,  or  engage  a  third  party  to  estimate,  potential  reserves  in  areas  to  be  developed  prior  to
constructing facilities in those areas. To the extent we rely on estimates of future production in deciding to construct additions to our systems, those estimates may
prove to be inaccurate either in volume or timing due to numerous uncertainties inherent in estimating future production. To the extent estimates of the volume of
new production are inaccurate, new facilities may not be able to attract sufficient throughput to achieve expected investment return, which could adversely affect
our  financial  position,  results  of  operations  and  ability  to  make  cash  distributions  to  unitholders.  To  the  extent  estimates  in  the  timing  of  new  production  are
inaccurate, new facilities may be constructed in advance of the actual need for capacity or may not be constructed in time to accommodate volume flows, which
could adversely affect our financial position, results of operations and ability to make cash distributions to unitholders. In addition, the construction of additions to
existing  gathering  and  transportation  assets  may  require  new  rights-of-way  prior  to  construction.  Those  rights-of-way  to  connect  new  natural  gas  supplies  to
existing  gathering  lines  may  be  unavailable  and  we  may  not  be  able  to  capitalize  on  attractive  expansion  opportunities.  Additionally,  it  may  become  more
expensive to obtain new rights-of-way or to renew existing rights-of-way. If the cost of renewing or obtaining new rights-of-way increases, our financial position,
results of operations and ability to make cash distributions to unitholders could be adversely affected.

Our  financial  position,  results  of  operations  and  ability  to  make  cash  distributions  to  unitholders  could  be  negatively  affected  by  adverse  changes  in  the
prices of natural gas, NGLs and crude oil depending on factors that are beyond our control. These factors include demand for these commodities, which fluctuates
with  changes  in  market  and  economic  conditions  and  other  factors,  including  the  impact  of  seasonality  and  weather,  general  economic  conditions,  the  level  of
domestic and offshore natural gas production and consumption, the availability of imported natural gas, LNG, NGLs and crude oil, actions taken by foreign natural
gas  and  oil  producing  nations,  the  availability  of  local,  intrastate  and  interstate  transportation  systems,  the  availability  and  marketing  of  competitive  fuels,  the
impact of energy conservation efforts, technological advances affecting energy consumption and the extent of governmental regulation and taxation.

Our natural gas processing arrangements expose us to commodity price fluctuations. In 2018 , 6% , 27% , and 67% of our processing plant inlet volumes

consisted of keep-whole arrangements, percent-of-proceeds or percent-of-liquids, and fee-based, respectively. If the price at which we sell natural gas or NGLs is
less than the cost at which we purchase natural gas or NGLs under these arrangements, then our financial position, results of operations and ability to make cash
distributions to unitholders could be adversely affected.

At any given time, our overall portfolio of processing contracts may reflect a net short position in natural gas (meaning that we are a net buyer of natural gas)
and  a  net  long  position  in  NGLs (meaning  that  we  are  a  net  seller  of  NGLs). As a  result,  our  financial  position,  results  of  operations  and  ability  to  make  cash
distributions to unitholders could be adversely affected to the extent the price of NGLs decreases in relation to the price of natural gas.

We 
are 
exposed 
to 
credit 
risks 
of 
our 
customers, 
and 
any 
material 
nonpayment 
or 
nonperformance 
by 
our 
customers 
could 
adversely 
affect 
our 
financial
position,
results
of
operations
and
ability
to
make
cash
distributions
to
unitholders.

Some  of  our  customers  may  experience  financial  problems  that  could  have  a  significant  effect  on  their  creditworthiness.  Severe  financial  problems
encountered by our customers could limit our ability to collect amounts owed to us, or to enforce performance of obligations under contractual arrangements. In
addition, many of our customers finance their activities through cash flow from operations, the incurrence of debt or the issuance of equity. The combination of
reduction of cash flow resulting from declines in commodity prices, a reduction in borrowing bases under reserve-based credit facilities and the lack of availability
of debt or equity financing may result in a significant reduction of our customers’ liquidity and limit their ability to make payment or perform on their obligations
to us. Furthermore, some of our customers may be highly leveraged and subject to their own operating and regulatory risks, which increases the risk that they may
default on their obligations to us. Financial problems experienced by our customers could result in the impairment of our assets, reduction of our operating cash
flows and may also reduce or curtail their future use of our products and services, which could reduce our revenues.

We 
provide 
certain 
transportation 
and 
storage 
services 
under 
fixed-price 
“negotiated 
rate” 
contracts 
that 
are 
not 
subject 
to 
adjustment, 
even 
if 
our 
cost 
to
perform
such
services
exceeds
the
revenues
received
from
such
contracts,
and,
as
a
result,
our
costs
could
exceed
our
revenues
received
under
such
contracts.

We  have  been  authorized  by  the  Federal  Energy  Regulatory  Commission,  or  FERC,  to  provide  transportation  and  storage  services  at  our  facilities  at
negotiated  rates.  As  of  December  31,  2018  ,  approximately  44%  of  our  aggregate  contracted  firm  transportation  capacity  on  EGT  and  MRT  and  45%  of  our
aggregate  contracted  firm  storage  capacity  on  EGT  and  MRT,  was  subscribed  under  such  “negotiated  rate”  contracts.  These  contracts  generally  do not  include
provisions  allowing  for  adjustment  for  increased  costs  due  to  inflation,  pipeline  safety  activities  or  other  factors  that  are  not  tied  to  an  applicable  tracking
mechanism authorized by FERC. Successful recovery of any shortfall of revenue, representing the difference between “recourse rates” (if higher) and negotiated
rates, is not assured under current FERC policies. If our costs increase and we are not able to recover any shortfall of revenue associated with our negotiated rate
contracts, the cash flow realized by our systems could decrease and, therefore, the cash we have available for distribution to our unitholders could also decrease.

If
third-party
pipelines
and
other
facilities
interconnected
to
our
gathering,
processing
or
transportation
facilities
become
partially
or
fully
unavailable
to
us
for
any
reason
,
our
financial
position,
results
of
operations
and
ability
to
make
cash
distributions
to
unitholders
could
be
adversely
affected.

We depend upon (i) third-party pipelines to deliver natural gas to, and take natural gas from, our natural gas transportation systems, (ii) third-party pipelines
and other facilities to take crude oil from our crude oil gathering systems, and, in some cases, (iii) third-party facilities to process natural gas from our gathering
systems. We also depend on third-party facilities to transport and fractionate NGLs that are delivered to the third party at the tailgates of our processing plants.
Fractionation is the separation of the heterogeneous mixture of extracted NGLs into individual components for end-use sale. For example, an outage or disruption
on  certain  pipelines  or  fractionators  operated  by  a  third  party  could  result  in  the  shutdown  of  certain  of  our  processing  plants  and  gathering  systems,  and  a
prolonged outage or disruption could ultimately result in a reduction in the volume of natural gas we gather and NGLs we are able to produce. Additionally, we
depend on third parties to provide electricity for compression at many of our facilities. Since we do not own or operate any of these third-party pipelines or other
facilities, their continuing operation is not within our control. If any of these third-party pipelines or other facilities become partially or fully unavailable to us for
any reason , our financial position, results of operations and ability to make cash distributions to unitholders could be adversely affected.

We
do
not
own
all
of
the
land
on
which
our
pipelines
and
facilities
are
located,
which
could
disrupt
our
operations.

We do not own all of the land on which our pipelines and facilities have been constructed, and we are therefore subject to the possibility of more onerous
terms and/or increased costs to retain necessary land use if we do not have valid rights-of-way or if such rights-of-way lapse or terminate. We may obtain the rights
to  construct  and  operate  our  pipelines  for  a  specific  period  of  time  on  lands  owned  by  governmental  agencies,  American  Indian  tribes,  or  other  third  parties,
including on American Indian allotments, title to which is held in trust by the United States. A loss of these rights, through our inability to renew right-of-way
contracts or otherwise, could cause us to cease operations temporarily or permanently on the affected land, increase costs related to the construction and continuing
operations elsewhere, and adversely affect our financial position, results of operations and ability to make cash distributions to unitholders.

We
conduct
a
portion
of
our
operations
through
joint
ventures,
which
subject
us
to
additional
risks
that
could
adversely
affect
the
success
of
these
operations
and
our
financial
position,
results
of
operations
and
ability
to
make
cash
distributions
to
unitholders.

We conduct a portion of our operations through joint ventures with third parties, including Enbridge Inc., DCP Midstream Partners, LP, CVR Refining, LP,
Trans Louisiana Gas Pipeline, Inc. and Pablo Gathering LLC. We may also enter into other joint venture arrangements in the future. These third parties may have
obligations  that  are  important  to  the  success  of  the  joint  venture,  such  as  the  obligation  to  pay  their  share  of  capital  and  other  costs  of  the  joint  venture.  The
performance of these third-party obligations, including the ability of the third parties to satisfy their obligations under these arrangements, is outside our control. If
these parties do not satisfy their obligations under these arrangements, our business may be adversely affected.

Our joint venture arrangements may involve risks not otherwise present when operating assets directly, including, for example:

•

•

our joint venture partners may share certain approval rights over major decisions;

our joint venture partners may not pay their share of the joint venture’s obligations, leaving us liable for their shares of joint venture liabilities;

36

 
 
 
 
 
 
 
 
Table of Contents

•

•

•

•

•

•

we may be unable to control the amount of cash we will receive from the joint venture;

we may incur liabilities as a result of an action taken by our joint venture partners;

we may be required to devote significant management time to the requirements of and matters relating to the joint ventures;

our insurance policies may not fully cover loss or damage incurred by both us and our joint venture partners in certain circumstances;

our joint venture partners may be in a position to take actions contrary to our instructions or requests or contrary to our policies or objectives; and

disputes between us and our joint venture partners may result in delays, litigation or operational impasses.

The risks described above or the failure to continue our joint ventures or to resolve disagreements with our joint venture partners could adversely affect our
ability to transact the business that is the subject of such joint venture, which would in turn adversely affect our financial position, results of operations and ability
to make cash distributions to unitholders. The agreements under which we formed certain joint ventures may subject us to various risks, limit the actions we may
take with respect to the assets subject to the joint venture and require us to grant rights to our joint venture partners that could limit our ability to benefit fully from
future  positive  developments.  Some  joint  ventures  require  us  to  make  significant  capital  expenditures.  If  we  do  not  timely  meet  our  financial  commitments  or
otherwise  do  not  comply  with  our  joint  venture  agreements,  our  rights  to  participate,  exercise  operator  rights  or  otherwise  influence  or  benefit  from  the  joint
venture may be adversely affected. Certain of our joint venture partners may have substantially greater financial resources than we have, and we may not be able to
secure the funding necessary to participate in operations our joint venture partners propose, thereby reducing our ability to benefit from the joint venture.

Under
certain
circumstances,
Enbridge
Inc.
could
have
the
right
to
purchase
an
ownership
interest
in
SESH
at
fair
market
value.

We  own  a  50% ownership  interest  in  SESH.  The  remaining  50%  ownership  interests  are  held  by  Enbridge  Inc.  As  of  December  31, 2018  , CenterPoint
Energy owns 54.0% of our common units, 100% of our Series A Preferred Units and a 40% economic interest in our general partner. Pursuant to the terms of the
limited liability company agreement of SESH, as amended (the SESH LLC Agreement), if, at any time, CenterPoint Energy has a right to receive less than 50% of
our distributions through its interests in us and in our general partner, or does not have the ability to exercise certain control rights, Enbridge Inc. could have the
right to purchase our interest in SESH at fair market value, subject to certain exceptions.

An
impairment
of
long-lived
assets,
including
intangible
assets,
equity
method
investments
or
goodwill
could
reduce
our
earnings.

Long-lived assets, including intangible assets with finite useful lives and property, plant and equipment, are evaluated for impairment when events or changes
in  circumstances  indicate  that  the  carrying  amount  may  not  be  recoverable.  An  impairment  of  long-lived  assets  is  recognized  if  the  carrying  amount  is  not
recoverable and exceeds fair value.

Equity  method  investments  are  evaluated  for  impairment  when  events  or  circumstances  indicate  that  the  carrying  value  of  the  investment  might  not  be
recoverable. An impairment of an equity method investment is recognized if the fair value of the investment as a whole, and not the underlying assets, has declined
and the decline is other than temporary. An example of an investment that we account for under the equity method is our investment in SESH. If we enter into
additional joint ventures, we could have additional equity method investments.

Goodwill is evaluated for impairment on an annual basis as well as when events or circumstances change that would more likely than not reduce the fair
value of a reporting unit to below its carrying amount. An impairment of goodwill is recognized if the carrying value of a reporting unit exceeds its fair value and
the carrying amount of that reporting unit’s goodwill exceeds the implied value of that goodwill. As of December 31, 2018 , we have goodwill of $98 million as a
result of the acquisition of Velocity Holdings, LLC in the fourth quarter of 2018 and Align Midstream, LLC in the fourth quarter of 2017.

We could experience future events or circumstances that result in an impairment of long-lived assets, including intangible assets, equity method investments,
or  goodwill.  If  we  recognize  an  impairment,  we  would  take  an  immediate  non-cash  charge  to  earnings  with  a  correlative  effect  on  equity  and  balance  sheet
leverage as measured by debt to total capitalization. As a result, an impairment could have an adverse effect on our results of operations and our ability to satisfy
the financial ratios or other covenants under our existing or future debt agreements.

Our 
business 
involves 
many 
hazards 
and 
operational 
risks, 
some 
of 
which 
may 
not 
be 
fully 
covered 
by 
insurance. 
Insufficient 
insurance 
coverage 
and
increased
insurance
costs
could
adversely
affect
our
financial
position,
results
of
operations
and
our
ability
to
make
cash
distributions
to
unitholders.

Our  operations  are  subject  to  all  of  the  risks  and  hazards  inherent  in  the  gathering,  processing,  transportation  and  storage  of  natural  gas  and  crude  oil,

including:

•

•

•

•

•

damage  to  pipelines  and  plants,  related  equipment  and  surrounding  properties  caused  by  hurricanes,  tornadoes,  floods,  fires,  earthquakes  and  other
natural disasters, acts of terrorism and actions by third parties;

inadvertent damage from construction, vehicles and farm and utility equipment;

leaks of natural gas, NGLs, crude oil and other hydrocarbons or losses of natural gas, NGLs and crude oil as a result of the malfunction of equipment or
facilities;

ruptures, fires and explosions; and

other hazards that could also result in personal injury and loss of life, pollution and suspension of operations.

These risks could result in substantial losses due to personal injury or loss of life, severe damage to and destruction of property, plant and equipment and
pollution or other environmental damage. These risks may also result in curtailment or suspension of our operations. A natural disaster or other hazard affecting the
areas in which we operate could adversely affect our results of operations. We are not fully insured against all risks inherent in our business. We currently have
general liability and property insurance in place to cover certain of our facilities in amounts that we consider appropriate. Such policies are subject to certain limits
and deductibles. We have business interruption insurance coverage for some but not all of our operations. Insurance coverage may not be available in the future at
current costs or on commercially reasonable terms, and the insurance proceeds received for any loss of, or any damage to, any of our facilities may not be sufficient
to restore the loss or damage without adversely affecting our financial position, results of operations and our ability to make cash distributions to unitholders.

The 
use 
of 
derivative 
contracts 
by 
us 
and 
our 
subsidiaries 
in 
the 
normal 
course 
of 
business 
could 
result 
in 
financial 
losses 
that 
could 
adversely 
affect 
our
financial
position,
results
of
operations
and
our
ability
to
make
cash
distributions
to
unitholders.

We  and  our  subsidiaries  periodically  use  derivative  instruments,  such  as  swaps,  options,  futures  and  forwards,  to  manage  our  commodity  and  financial
market risks. We and our subsidiaries could recognize financial losses as a result of volatility in the market values of these contracts, or should a counterparty fail
to perform. In the absence of actively quoted market prices and pricing information from external sources, the valuation of these financial instruments can involve
management’s judgment or use of estimates. As a result, changes in the underlying assumptions or use of alternative valuation methods could affect the reported
fair value of these contracts.

Failure
to
attract
and
retain
an
appropriately
qualified
workforce
could
adversely
impact
our
results
of
operations.

Our business is dependent on our ability to recruit, retain and motivate employees. Certain circumstances, such as an aging workforce without appropriate
replacements,  a  mismatch  of  existing  skill  sets  to  future  needs,  competition  for  skilled  labor  or  the  unavailability  of  contract  resources  may  lead  to  operating
challenges such as a lack of resources, loss of knowledge or a lengthy time period associated with skill development. Our costs, including costs for contractors to
replace employees, productivity costs and safety costs, may rise. Failure to hire and adequately train replacement employees, including the transfer of significant
internal historical knowledge and expertise to the new employees, or the future availability and cost of contract labor may adversely affect our ability to manage
and  operate  our  business.  If  we are  unable  to  successfully  attract  and  retain  an appropriately  qualified  workforce,  our results  of  operations  could be  negatively
affected.

As of December 31, 2018 , we have 89 employees who are participants under OGE Energy’s defined benefit and retiree medical plans, who are seconded to
the Partnership, subject to certain termination rights of the Partnership and OGE Energy. If seconding is terminated, employees of OGE Energy that we determine
to hire are under no obligation to accept our offer of employment on the terms we provide, or at all.

Our
ability
to
grow
is
dependent
in
part
on
our
ability
to
access
external
financing
sources
on
acceptable
terms.

Our operating subsidiaries distribute all of their available cash to us, and we distribute all of our available cash to our unitholders. As a result, we and our
operating subsidiaries rely significantly upon external financing sources, including commercial bank borrowings and the issuance of debt and equity securities, to
fund acquisitions and expansion capital expenditures. To the extent we or our operating subsidiaries are unable to finance growth externally or through internally
generated cash flows, our

38

 
 
 
 
 
 
Table of Contents

and our operating subsidiaries’ cash distribution policy may significantly impair our and our operating subsidiaries’ ability to grow. In addition, because we and
our operating subsidiaries distribute all available cash, our and our operating subsidiaries’ growth may not be as fast as businesses that reinvest their available cash
to  expand  ongoing  operations.  For  further  information  related  to  distributions  of  available  cash,  please  see  Item  7. “Management’s  Discussion  and  Analysis  of
Financial Condition and Results of Operations.”

To the extent we issue additional units in connection with any acquisitions or expansion capital expenditures, the payment of distributions on those additional
units may increase the risk that we will be unable to maintain or increase our per unit distribution level, which in turn may impact the available cash that we have
to  distribute  on  each  unit.  There  are  no  limitations  in  our  Partnership  Agreement  on  our  ability  to  issue  additional  units,  including  units  ranking  senior  to  the
common units. The incurrence of additional commercial borrowings or other debt by us or our operating subsidiaries to finance our growth strategy would result in
increased  interest  expense,  which  in  turn  may  negatively  impact  the  available  cash  that  our  operating  subsidiaries  have  to  distribute  to  us, and  that  we have  to
distribute to our unitholders.

We depend in part on access to the capital markets and other external financing sources to fund our expansion capital expenditures, although we have also
increasingly relied on cash flow generated from our operations to fund our expansion capital expenditures. Historically, unit prices of midstream master limited
partnerships have experienced periods of volatility. In addition, because our common units are yield-based securities, rising market interest rates could impact the
relative attractiveness of our common units to investors. As a result of capital market volatility, we may be unable to issue equity or debt on satisfactory terms, or
at all, which may limit our ability to expand our operations or make future acquisitions.

I n the first quarter of 2016, CenterPoint Energy announced that it was evaluating strategic alternatives for its investment in Enable. In the first quarter of
2018, CenterPoint Energy disclosed that it had decided not to pursue a sale or spin-off qualifying under Section 355 of the U.S. Internal Revenue Code at that time
and that, while a transaction for all of its interests in the Partnership was not viable at that time, it may pursue such a transaction if it becomes viable in the future.
CenterPoint Energy also disclosed that it may reduce its investment in the Partnership through a sale of all or a portion of the Partnership common units it owns in
the public equity markets or otherwise, subject to certain limitations. CenterPoint Energy’s disclosure, as well as any sales by CenterPoint Energy of the common
units it holds in the public equity markets, could have an adverse impact on the market for our common units, including our ability to issue equity on favorable
terms to fund our capital needs or at all.

Our
merger
and
acquisition
activities
may
not
be
successful
or
may
result
in
completed
acquisitions
that
do
not
perform
as
anticipated,
which
could
adversely
affect
our
financial
position,
results
of
operations
or
future
growth.

From  time  to  time,  we  have  made,  and  we  intend  to  continue  to  make,  acquisitions  of  businesses  and  assets.  Such  acquisitions  involve  substantial  risks,

including the following:

•
•
•
•

•

acquired businesses or assets may not produce revenues, earnings or cash flow at anticipated levels;
acquired businesses or assets could have environmental, permitting or other problems for which contractual protections prove inadequate;
we may assume liabilities that were not disclosed to us, that exceed our estimates, or for which our rights to indemnification from the seller are limited;
we may be unable to integrate acquired businesses successfully and realize anticipated economic, operational and other benefits in a timely manner,
which could result in substantial costs and delays or other operational, technical or financial problems; and
acquisitions, or the pursuit of acquisitions, could disrupt our ongoing businesses, distract management, divert resources and make it difficult to maintain
our current business standards, controls and procedures.

In addition, our growth strategy includes, in part, the ability to make acquisitions on economically acceptable terms. If we are unable to make acquisitions or if our
acquisitions do not perform as anticipated, our future growth may be adversely affected.

Our 
and 
our 
operating 
subsidiaries’ 
debt 
levels 
may 
limit 
our 
and 
their 
flexibility 
in 
obtaining 
additional 
financing 
and 
in 
pursuing 
other 
business
opportunities.

As  of  December  31,  2018  ,  we  had  approximately  $2.9  billion  of  long-term  debt  outstanding,  excluding  the  premiums,  discounts  and  unamortized  debt
expense  on  senior  notes.  In  addition,  as  of  December  31,  2018  ,  we  had  $649  million  outstanding  under  our  commercial  paper  program  and  $500  million
outstanding  under  our  2019  Notes,  excluding  unamortized  debt  expense.  We  have  a  $1.75  billion  Revolving  Credit  Facility  for  working  capital,  capital
expenditures  and  other  partnership  purposes,  including  acquisitions,  with  approximately  $250  million  in  borrowings  outstanding  and  $848  million  remaining
available as of February 1,

39

 
 
 
 
Table of Contents

2019 . We  have  the  ability  to  incur  additional  debt,  subject  to  limitations  in  our  credit  facilities.  The  levels  of  our  debt  could  have  important  consequences,
including the following:

•

•

•

•

the ability to obtain additional financing, if necessary, for working capital, capital expenditures, acquisitions or other purposes may be impaired or the
financing may not be available on favorable terms, if at all;

a portion of cash flows will be required to make interest payments on the debt, reducing the funds that would otherwise be available for operations,
future business opportunities and distributions;

our debt level will make us more vulnerable to competitive pressures or a downturn in our business or the economy generally; and

our debt level may limit our flexibility in responding to changing business and economic conditions.

Our  and  our  operating  subsidiaries’  ability  to  service  our  and  their  debt  will  depend  upon,  among  other  things,  their  future  financial  and  operating
performance, which will be affected by prevailing economic conditions, commodity prices and financial, business, regulatory and other factors, some of which are
beyond our and their control. If operating results are not sufficient to service our or our operating subsidiaries’ current or future indebtedness, we and they may be
forced  to  take  actions  such  as  reducing  distributions,  reducing  or  delaying  business  activities,  acquisitions,  investments  or  capital  expenditures,  selling  assets,
restructuring  or  refinancing  debt,  or  seeking  additional  equity  capital.  These  actions  may  not  be  effected  on  satisfactory  terms,  or  at  all.  Please  see  Item  7.
“Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources.”

Our
credit
facilities
contain
operating
and
financial
restrictions,
including
covenants
and
restrictions
that
may
be
affected
by
events
beyond
our
control,
which
could
adversely
affect
our
financial
condition,
results
of
operations
and
ability
to
make
cash
distributions
to
our
unitholders.

Our credit facilities contain customary covenants that, among other things, limit our ability to:

•

•

•

permit our subsidiaries to incur or guarantee additional debt;

incur or permit to exist certain liens on assets;

dispose of assets;

• merge or consolidate with another company or engage in a change of control;

•

•

enter into transactions with affiliates on non-arm’s length terms; and

change the nature of our business.

Our credit facilities also require us to maintain certain financial ratios. Our ability to meet those financial ratios can be affected by events beyond our control,

and we cannot assure you that we will meet those ratios. In addition, our credit facilities contain events of default customary for agreements of this nature.

Our ability to comply with the covenants and restrictions contained in our credit facilities may be affected by events beyond our control, including prevailing
economic, financial and industry conditions. If market or other economic conditions deteriorate, our ability to comply with these covenants may be impaired. If we
violate any of the restrictions, covenants, ratios or tests in our credit facilities, a significant portion of our indebtedness may become immediately due and payable.
In addition, our lenders’ commitments to make further loans to us under the Revolving Credit Facility may be suspended or terminated. We might not have, or be
able to obtain, sufficient funds to make these accelerated payments. Please see Item 7. “Management’s Discussion and Analysis of Financial Condition and Results
of Operations—Liquidity and Capital Resources.”

Affiliates
of
our
general
partner,
including
CenterPoint
Energy
and
OGE
Energy,
may
compete
with
us,
and
neither
our
general
partner
nor
its
affiliates
have
any
obligation
to
present
business
opportunities
to
us.

Under  our  omnibus  agreement,  both  CenterPoint  Energy  and  OGE  Energy  are  prohibited  from,  directly  or  indirectly,  owning,  operating,  acquiring  or
investing in any business engaged in midstream operations located within the United States, other than through us. This requirement applies to both CenterPoint
Energy and OGE Energy for so long as either CenterPoint Energy or OGE Energy holds any interest in our general partner or at least 20% of our common units.
However, if CenterPoint Energy or OGE Energy acquires any business with midstream operations assets that have a value in excess of $50 million (or $100 million
in the aggregate with such party’s other acquired midstream operations assets that have not been offered to us), the acquiring party will be required to offer to us
such assets for such value. If we do not purchase such assets, the acquiring party will be free to retain and operate such midstream assets, so long as the value of the
assets does not reach certain thresholds.

As  a  result,  under  the  circumstances  described  above,  CenterPoint  Energy  and  OGE  Energy  have  the  ability  to  construct  or  acquire  assets  that  directly
compete with our assets. Pursuant to the terms of our Partnership Agreement, the doctrine of corporate opportunity, or any analogous doctrine, does not apply to
our general partner or any of its affiliates, including its executive officers and directors and CenterPoint Energy and OGE Energy. Any such person or entity that
becomes aware of a potential transaction, agreement, arrangement or other matter that may be an opportunity for us will not have any duty to communicate or offer
such opportunity to us. Any such person or entity will not be liable to us or to any limited partner for breach of any fiduciary duty or other duty by reason of the
fact that such person or entity pursues or acquires such opportunity for itself, directs such opportunity to another person or entity or does not communicate such
opportunity or information to us. This may create actual and potential conflicts of interest between us and affiliates of our general partner and result in less than
favorable treatment of us and our common unitholders.

If
we
fail
to
maintain
an
effective
system
of
internal
controls,
then
we
may
not
be
able
to
accurately
report
our
financial
results
or
prevent
fraud.
As
a
result,
current
and
potential
unitholders
could
lose
confidence
in
our
financial
reporting,
which
would
harm
our
business
and
the
trading
price
of
our
common
units.

Effective internal controls are necessary for us to provide reliable financial reports, prevent fraud and operate successfully as a public company. If our efforts
to maintain an effective system of internal controls are not successful, we are unable to maintain adequate controls over our financial processes and reporting in the
future or we are unable to comply with our obligations under Section 404 of the Sarbanes-Oxley Act of 2002, our operating results could be harmed or we may fail
to meet our reporting obligations. Ineffective  internal controls also could cause investors to lose confidence in our reported financial information, which would
likely have a negative effect on the trading price of our common units.

Cybersecurity
attacks
or
other

of
our
systems,
networks
and
technology
could
adversely
impact
our
financial
position,
results
of
operations
and
ability

to
unitholders.

We have become increasingly dependent on the systems, networks and technology that we use to conduct almost all aspects of our business, including the
operation of our gathering, processing, transportation and storage assets, the recording of commercial transactions, and the reporting of financial information. We
depend on both our own systems, networks, and technology as well as the systems, networks and technology of our vendors, customers and other business partners.
Any disruption of these systems, networks and technology could disrupt the operation of our business. Disruptions can result from a variety of causes, including
natural disasters, the failure of software or equipment, and manmade events, such as cybersecurity attacks or information security breaches. Cybersecurity attacks
and information security breaches could result in the unauthorized use of confidential, proprietary or other information and in the disruption of our critical business
functions and operations, adversely affecting our reputation, and subjecting us to possible legal claims and liability. In addition, we are not fully insured against all
cybersecurity risks .

As cybersecurity attacks continue to evolve, we may be required to expend significant additional resources to continue to modify or enhance our protective
measures  or  to  investigate  and  remediate  any  vulnerabilities  to  cybersecurity  attacks.  In  particular,  our  implementation  of  various  procedures  and  controls  to
monitor  and  mitigate  security  threats  and  to  increase  security  for  our  personnel,  information,  facilities  and  infrastructure  may  result  in  increased  capital  and
operating costs. To date we have not experienced any material losses relating to cybersecurity attacks; however, there can be no assurance that we will not suffer
such losses in the future. Consequently, it is possible that any of these occurrences, or a combination of them, could adversely affect our financial position, results
of operations and ability to make cash distributions to unitholders.

Terrorist
attacks
or
other
physical
security
threats
could
adversely
affect
our
business.

Our  gathering,  processing,  transportation  and  storage  assets  may  be  targets  of  terrorist  activities  or  other  physical  security  threats  that  could  disrupt  our
ability  to  conduct  our  business.  It  is  possible  that  any  of  these  occurrences,  or  a  combination  of  them,  could  adversely  affect  our  financial  position,  results  of
operations, and ability to make cash distributions to unitholders. In addition, any physical damage to our assets resulting from acts of terrorism may not be fully
covered by our insurance.

We
may
be
unable
to
obtain
or
renew
permits
necessary
for
our
operations,
which
could
inhibit
our
ability
to
do
business.

Performance of our operations require that we obtain and maintain a number of federal and state permits, licenses and approvals with terms and conditions
containing a significant number of prescriptive limits and performance standards in order to operate. All of these permits, licenses, approval limits and standards
require a significant amount of monitoring, record keeping and reporting in order to demonstrate compliance with the underlying permit, license, approval limit or
standard. Noncompliance or incomplete documentation of our compliance status may result in the imposition of fines, penalties and injunctive relief. A decision by
a government agency to deny or delay the issuance of a new or existing material permit or other approval, or to revoke or substantially modify an existing permit or
other approval, could adversely affect our ability to initiate or continue operations

41

at the affected location or facility and on our financial condition, results of operations and ability to make cash distributions to unitholders.

Additionally,  in  order  to  obtain  permits  and  renewals  of  permits  and  other  approvals  in  the  future,  we  may  be  required  to  prepare  and  present  data  to
governmental  authorities  pertaining  to  the  potential  adverse  impact  that  any  proposed  pipeline  or  processing-related  activities  may  have  on  the  environment,
individually  or  in  the  aggregate,  including  on  public  and  American  Indian  tribal  lands.  Certain  approval  procedures  may  require  preparation  of  archaeological
surveys,  wetland  delineations,  endangered  species  surveys  and  other  studies  to  assess  the  environmental  impact  of  new  sites  or  the  expansion  of  existing  sites.
Compliance  with  these  regulatory  requirements  may  be  expensive  and  may  significantly  lengthen  the  time  required  to  prepare  applications  and  to  receive
authorizations and consequently could disrupt our project construction schedules.

Costs 
of 
compliance 
with 
existing 
environmental 
laws 
and 
regulations 
are 
significant, 
and 
the 
cost 
of 
compliance

We are subject to extensive federal, state and local environmental statutes, rules and regulations relating to air quality, water quality, waste management,
wildlife conservation, natural resources and health and safety that could, among other things, delay or increase our costs of construction, restrict or limit the output
of  certain  facilities  and/or  require  additional  pollution  control  equipment  and  otherwise  increase  costs.  For  instance,  in  May  2016, the  EPA  issued  final  NSPS,
known  as  subpart  OOOOa,  governing  methane  emissions  imposing  more  stringent  controls  on  methane  and  volatile  organic  compounds  emissions  at  new  and
modified  oil  and  natural  gas  production,  processing,  storage,  and  transmission  facilities.  These  rules  have  required  changes  to  our  operations,  including  the
installation of new equipment to control emissions. Following the change in presidential administrations, there have been attempts to modify these regulations, and
litigation concerning the regulations is ongoing. As a result, we cannot predict the scope of any final methane regulatory requirements or the cost to comply with
such requirements. However, several states are pursuing similar measures to regulate emissions of methane from new and existing sources. There are significant
capital, operating and other costs associated with compliance with these environmental statutes, rules and regulations. Future federal and state regulations relating
to  our  gathering  and  processing,  transmission,  and  storage  operations  remain  a  possibility  and  could  result  in  increased  compliance  costs  on  our  operations.
Furthermore,  if  new  or  more  stringent  federal,  state  or  local  legal  restrictions  are  adopted  in  areas  where  our  oil  and  natural  gas  exploration  and  production
customers  operate,  they  could  incur  potentially  significant  added  costs  to  comply  with  such  requirements,  experience  delays  or  curtailment  in  the  pursuit  of
exploration, development, or production activities, and perhaps even be precluded from drilling wells, some or all of which could adversely affect demand for our
services to those customers.

There  is  inherent  risk  of  the  incurrence  of  environmental  costs  and  liabilities  in  our  operations  due  to  our  handling  of  natural  gas,  NGLs,  crude  oil,  and
produced  water,  as  well  as  air  emissions  related  to  our  operations  and  historical  industry  operations  and  waste  disposal  practices.  These  matters  are  subject  to
stringent and complex federal, state and local laws and regulations governing environmental protection, including the discharge of materials into the environment
and the protection of plants, wildlife, and natural and cultural resources. These laws and regulations can restrict or impact our business activities in many ways,
such as restricting the way we can handle or dispose of wastes or requiring remedial action to mitigate pollution conditions that may be caused by our operations or
that are attributable to former operators. Joint and several strict liability may be incurred, without regard to fault, under certain of these environmental laws and
regulations  in  connection  with  discharges  or  releases  of  wastes  on,  under  or  from  our  properties  and  facilities,  many  of  which  have  been  used  for  midstream
activities  for  a  number  of  years,  oftentimes  by  third  parties  not  under  our  control.  Private  parties,  including  the  owners  of  the  properties  through  which  our
gathering and transportation systems pass and facilities where our wastes are taken for reclamation or disposal, may also have the right to pursue legal actions to
enforce  compliance,  as  well  as  to  seek  damages  for  non-compliance,  with  environmental  laws  and  regulations  or  for  personal  injury  or  property  damage.  For
example, an accidental release from one of our pipelines could subject us to substantial liabilities arising from environmental cleanup and restoration costs, claims
made by neighboring landowners and other third parties for personal injury and property damage and fines or penalties for related violations of environmental laws
or  regulations.  We  may  be  unable  to  recover  these  costs  from  insurance.  Moreover,  the  possibility  exists  that  stricter  laws,  regulations  or  enforcement  policies
could significantly increase compliance costs and the cost of any remediation that may become necessary. Further, stricter requirements could negatively impact
our customers’ production and operations, resulting in less demand for our services.

Hydraulic fracturing is a common practice that is used by many of our customers to stimulate production of natural gas and crude oil from dense subsurface
rock  formations.  The  hydraulic  fracturing  process  involves  the  injection  of  water,  sand,  and  chemicals  under  pressure  into  targeted  subsurface  formations  to
fracture the surrounding rock and stimulate production. Hydraulic

42

 
 
 
 
 
 
Table of Contents

fracturing typically is regulated by state oil and natural gas commissions. In addition, certain federal agencies have proposed additional laws and regulations to
more closely regulate the hydraulic fracturing process. In past sessions, Congress has considered, but not passed, legislation to provide for federal regulation of
hydraulic fracturing under the Safe Drinking Water Act (SDWA) and to require disclosure of the chemicals used in the hydraulic fracturing process. The EPA has
issued regulations and guidance for hydraulic fracturing operations under several statutes.

Some states have adopted, and other states have considered adopting, legal requirements that could impose more stringent permitting, public disclosure or
well  construction  requirements  on  hydraulic  fracturing  activities.  Local  government  also  may  seek  to  adopt  ordinances  within  their  jurisdictions  regulating  the
time, place and manner of drilling activities in general or hydraulic fracturing activities in particular, in some cases banning hydraulic fracturing entirely. If new or
more stringent federal, state or local legal restrictions relating to the hydraulic fracturing process are adopted in areas where our oil and natural gas exploration and
production  customers  operate,  they  could  incur  potentially  significant  added  costs  to  comply  with  such  requirements,  experience  delays  or  curtailment  in  the
pursuit of exploration, development, or production activities, and perhaps even be precluded from drilling wells, some or all of which activities could adversely
affect demand for our services to those customers.

State and federal regulatory agencies have also focused on a possible connection between the operation of injection wells used for oil and gas waste disposal
and seismic  activity. Similar concerns have been raised that hydraulic  fracturing may also contribute to seismic activity.  When caused by human activity, such
events  are  called  induced  seismicity.  In  March  2016,  the  United  States  Geological  Survey  identified  six  states  with  the  most  significant  hazards  from  induced
seismicity, including Oklahoma, Kansas, Texas, Colorado, New Mexico, and Arkansas. In March 2017, the United States Geological Survey produced an updated
seismic hazard survey that forecasted lower earthquake rates in regions of induced activity, but still showed significantly elevated hazards in the central and eastern
United  States.  In  light  of  these  concerns,  some  state  regulatory  agencies  have  modified  their  regulations  or  issued  orders  to  address  induced  seismicity.  For
example, the OCC has implemented volume reduction plans, and at times required shut-ins, for disposal wells injecting wastewater from oil and gas operations into
the Arbuckle formation. In February 2018, the OCC revised well completion seismicity guidelines for operators in the SCOOP and STACK to reduce the threshold
of seismic readings required to suspend hydraulic fracturing operations in some circumstances. Certain environmental and other groups have also suggested that
additional  federal,  state  and  local  laws  and  regulations  may  be  needed  to  more  closely  regulate  the  hydraulic  fracturing  process.  We  cannot  predict  whether
additional  federal,  state  or  local  laws  or  regulations  applicable  to  hydraulic  fracturing  will  be  enacted  in  the  future  and,  if  so,  what  actions  any  such  laws  or
regulations would require or prohibit. Increased regulation and attention given to induced seismicity could lead to greater opposition to, and litigation concerning,
oil and gas activities utilizing hydraulic fracturing or injection wells for waste disposal. Additional legislation or regulation could also lead to operational delays or
increased operating costs for our customers, which in turn could reduce the demand for our services.

Other governmental agencies, including the U.S. Department of Energy, have evaluated or are evaluating various other aspects of hydraulic fracturing. These
ongoing  or  proposed  studies,  depending  on  their  degree  of  pursuit  and  any  meaningful  results  obtained,  could  spur  initiatives  to  further  regulate  hydraulic
fracturing under the SDWA or other regulatory mechanisms.

Our
operations
may
incur
substantial
liabilities
to
comply
with
climate
change
legislation
and
regulatory
initiatives.

Because  our  operations  emit  various  types  of  greenhouse  gases,  legislation  and  regulations  governing  greenhouse  gas  emissions  could  increase  our  costs
related to operating and maintaining our facilities and could delay future permitting. At the federal level, the EPA has adopted regulations under existing provisions
of the federal Clean Air Act that, among other things, require the monitoring and reporting of GHG emissions from specified onshore and offshore oil and natural
gas production sources in the United States on an annual basis, which include certain of our operations. Additional rules, such as the updates to the oil and gas
NSPS requirements finalized by the EPA in May 2016 could affect our ability to obtain air permits for new or modified facilities or require our operations to incur
additional  expenses  to  control  air  emissions  by  installing  emissions  control  technologies  and  adhering  to  a  variety  of  work  practice  and  other  requirements.
Following the change in presidential administrations, there have been attempts to modify these regulations, and litigation concerning the regulations is ongoing. As
a result, we cannot predict the scope of any final methane regulatory requirements  or the cost to comply with such requirements.  If upheld, these requirements
could  increase  the  costs  of  development  and  production,  reducing  the  profits  available  to  us  and  potentially  impairing  our  operator’s  ability  to  economically
develop our properties.

In addition, the U.S. Congress has in the past and may in the future consider legislation to reduce emissions of greenhouse gases, and there has been a wide-
ranging policy debate, both nationally and internationally, regarding the impact of these gases and possible means for their regulation. Efforts have been made and
continue  to  be  made  in  the  international  community  toward  the  adoption  of  international  treaties  or  protocols  that  would  address  global  climate  change  issues.
From  time  to  time,  the  United  States  Congress  has  considered  adopting  legislation  to  limit  GHG  emissions.  A  number  of  state  and  regional  efforts  have  also
emerged that are aimed at tracking and/or reducing GHG emissions by means of cap and trade programs. These programs typically

43

 
 
Table of Contents

require major sources of GHG emissions to acquire and surrender emission allowances in return for emitting those GHGs. Any such future laws and regulations
imposing reporting obligations on, or limiting emissions of, GHGs could require us to incur costs to reduce emissions of GHGs. Substantial limitations on GHG
emissions could also adversely affect demand for oil and natural gas. Depending on the particular program, we could in the future be required to purchase and
surrender emission allowances or otherwise undertake measures to reduce greenhouse gas emissions. Any additional costs or operating restrictions associated with
new  legislation  or  regulations  regarding  greenhouse  gas  emissions  could  adversely  affect  the  demand  for  our  services  and  our  financial  position,  results  of
operations and ability to make cash distributions to unitholders.

Increased regulatory-imposed costs may also increase the cost of consuming, and thereby reduce demand for, the products that we gather, treat and transport.
Notwithstanding potential risks related to climate change, the International Energy Agency estimates that oil and gas will continue to represent a major share of
global energy use through 2040, and other private sector studies project continued growth in demand for the next two decades.

Finally, some scientists have concluded that increasing concentrations of GHGs in the Earth’s atmosphere may produce climate changes that have significant
physical effects, such as increased frequency and severity of storms, floods and other climatic events. If any such effects were to occur, they could adversely affect
our results of operations.

The rates charged by several of our pipeline systems, including for interstate gas transportation service provided by our intrastate pipelines, are regulated by
FERC. FERC and state regulatory agencies also regulate other terms and conditions of the services we may offer. If one of these regulatory agencies, on its own
initiative  or  due  to  challenges  by  third  parties,  were  to  lower  our  tariff  rates  or  deny  any  rate  increase  or  other  material  changes  to  the  types,  or  terms  and
conditions,  of  service  we  might  propose  or  offer,  the  profitability  of  our  pipeline  businesses  could  suffer.  If  we  were  permitted  to  raise  our  tariff  rates  for  a
particular pipeline, there might be significant delay between the time the tariff rate increase is approved and the time that the rate increase actually goes into effect,
which  could  also  limit  our  profitability.  Furthermore,  competition  from  other  pipeline  systems  may  prevent  us  from  raising  our  tariff  rates  even  if  regulatory
agencies permit us to do so. The regulatory agencies that regulate our systems periodically implement new rules, regulations and terms and conditions of services
subject to their jurisdiction. New initiatives or orders may adversely affect the rates charged for our services or otherwise adversely affect our financial position,
results of operations and ability to make cash distributions to our unitholders.

Our natural gas interstate pipelines are regulated by FERC under the Natural Gas Act of 1938, or NGA, the Natural Gas Policy Act of 1978, or NGPA, and

the Energy Policy Act of 2005, or EPAct of 2005. Generally, FERC’s authority over interstate natural gas transportation extends to:

•

•

•

rates, operating terms, conditions of service and service contracts;

certification and construction of new facilities;

extension or abandonment of services and facilities or expansion of existing facilities;

• maintenance of accounts and records;

•

•

•

•

acquisition and disposition of facilities;

initiation and discontinuation of services;

depreciation and amortization policies;

conduct and relationship with certain affiliates;

• market manipulation in connection with interstate sales, purchases or natural gas transportation; and

•

various other matters.

Should we fail to comply with all applicable FERC-administered statutes, rules, regulations and orders, we could be subject to substantial penalties and fines.
Under the EPAct of 2005, FERC has civil penalty authority under the NGA and the NGPA to impose penalties for current violations of up to approximately $1.27
million per day for each violation and possible criminal penalties of up to approximately $1.27 million per violation.

FERC’s jurisdiction extends to the certification and construction of interstate transportation and storage facilities, including, but not limited to expansions,
lateral and other facilities  and abandonment of facilities and services. Prior to commencing construction of significant new interstate transportation  and storage
facilities, an interstate pipeline must obtain a certificate

44

 
 
Table of Contents

authorizing the construction, or an order amending its existing certificate, from FERC. Certain minor expansions are authorized by blanket certificates that FERC
has issued by rule. Typically, a significant  expansion project requires  review by a number of governmental agencies,  including state and local agencies, whose
cooperation  is  important  in  completing  the  regulatory  process  on  schedule.  Any  failure  by  an  agency  to  issue  sufficient  authorizations  or  permits  in  a  timely
manner for one or more of these projects may mean that we will not be able to pursue these projects or that they will be constructed in a manner or with capital
requirements that we did not anticipate. Our inability to obtain sufficient permits and authorizations in a timely manner could materially and negatively impact the
additional revenues expected from these projects.

FERC  conducts  audits  to  verify  compliance  with  FERC’s  regulations  and  the  terms  of  its  orders,  including  whether  the  websites  of  interstate  pipelines
accurately provide information on the operations and availability of services. FERC’s regulations require uniform terms and conditions for service, as set forth in
agreements for transportation and storage services executed between interstate pipelines and their customers. These service agreements are required to conform, in
all  material  respects,  with  the  standard  form  of  service  agreements  set  forth  in  the  pipeline’s  FERC-approved  tariff.  Non-conforming  agreements  must  be  filed
with, and accepted by, the FERC. In the event that FERC finds that an agreement, in whole or part, is materially non-conforming, it could reject the agreement or
require us to seek modification, or alternatively require us to modify our tariff so that the non-conforming provisions are generally available to all customers.

The rates, terms and conditions for transporting natural gas in interstate commerce on certain of our intrastate pipelines and for services offered at certain of
our storage facilities are subject to the jurisdiction of FERC under Section 311 of the NGPA. Rates to provide such interstate transportation service must be “fair
and equitable” under the NGPA and are subject to review, refund with interest if found not to be fair and equitable, and approval by FERC at least once every five
years.

Our crude oil gathering systems in the Williston Basin are subject to common carrier regulation by FERC under the Interstate Commerce Act, or ICA. The
ICA requires that we maintain tariffs on file with FERC setting forth the rates we charge for providing transportation services, as well as the rules and regulations
governing such services. The ICA also requires, among other things, that our rates must be “just and reasonable” and that we provide service in a manner that is
nondiscriminatory. Shippers on our FERC-regulated crude oil gathering systems may protest our tariff filings, file complaints against our existing rates, or FERC
can investigate our rates on its own initiative. If FERC finds that our existing or proposed rates are unjust and unreasonable, it could deny requested rate increases
or could order us to reduce our rates and could require the payment of reparations to complaining shippers for up to two years prior to the complaint.

On December 22, 2017, the Tax Cuts and Jobs Act was enacted, which reduced the highest marginal United States federal corporate income tax rate from
35% to 21% for tax years beginning after December 31, 2017. In a series of related issuances on March 15, 2018, the FERC issued a Revised Policy Statement
stating that it will no longer permit pipelines organized as master limited partnerships to recover an income tax allowance in their cost-of-service rates. On July 18,
2018,  FERC  issued  a  Final  Rule  adopting  procedures  that  are  generally  the  same  as  proposed  in  a  March  15,  2018  NOPR  implementing  the  Revised  Policy
Statement and the corporate income tax rate reduction with certain clarifications and modifications. For more information, please read Item 1, “Business-Rate and
Other Regulation.”

If FERC requires us to establish new tariff rates for either our natural gas or crude oil pipelines that reflect a lower federal corporate income tax rate, it is
possible  the  rates  would  be  reduced,  which  could  adversely  affect  our  financial  position,  results  of  operations  and  ability  to  make  cash  distributions  to  our
unitholders.

Our 
operations 
may 
also 
be 
subject

Our  pipeline  operations  that  are  not  regulated  by  FERC  may  be  subject  to  state  and  local  regulation  applicable  to  intrastate  natural  and  transportation
services.  State  and local  regulations  generally  focus on safety,  environmental  and, in some circumstances,  prohibition  of undue discrimination  among shippers.
Additional rules and legislation pertaining to these matters are considered and, in some instances, adopted from time to time. We cannot predict what effect, if any,
such changes might have on our operations, but we could be required to incur additional capital expenditures and increased costs depending on future legislative
and  regulatory  changes.  Other  state  and  local  regulations  also  may  affect  our  business.  Any  such  state  or  local  regulation  could  have  an  adverse  effect  on  our
business and our financial position, results of operations and ability to make cash distributions to unitholders. For more information, please read Item 1, “Business-
Rate and Other Regulation.”

A

Our  natural  gas  gathering  and  intrastate  transportation  systems  are  generally  exempt  from  the  jurisdiction  of  FERC  under  the  NGA,  and  our  crude  oil
gathering system in the Anadarko Basin is generally exempt from the jurisdiction of FERC under the ICA. Nevertheless, FERC regulation may indirectly impact
these businesses and the markets for products derived from these businesses. FERC’s policies and practices across the range of its oil and natural gas regulatory
activities, including, for example, its policies on interstate open access transportation, ratemaking, capacity release, and market center promotion may indirectly
affect  intrastate  markets.  In  recent  years,  FERC  has  pursued  pro-competitive  policies  in  its  regulation  of  interstate  oil  and  natural  gas  pipelines.  However,  we
cannot assure you that FERC will continue to pursue this approach as it considers matters such as pipeline rates and rules and policies that may indirectly affect the
intrastate natural gas transportation business. Although FERC has not made a formal determination with respect to all of our facilities we consider to be engaged in
natural gas gathering or a formal determination with respect to our facilities that we consider to be engaged in intrastate crude oil gathering, management believes
that  our  natural  gas  gathering  facilities  meet  the  traditional  tests  that  FERC  has  used  to  determine  that  a  pipeline  is  a  natural  gas  gathering  pipeline  and  our
intrastate crude oil gathering facilities meet the traditional tests that FERC has used to determine that a pipeline is not engaged in interstate crude oil transportation.
The distinction between FERC-regulated facilities, however, has been the subject of substantial litigation, and FERC determines whether facilities are subject to
regulation  under  the  NGA  or  the  ICA  on  a  case-by-case  basis,  so  the  classification  and  regulation  of  our  facilities  is  subject  to  change  based  on  future
determinations  by  FERC,  the  courts  or  Congress.  If  FERC  were  to  consider  the  status  of  an  individual  facility  and  determine  that  the  facility  and/or  services
provided by it are not exempt from FERC regulation, the rates for, and terms and conditions of, services provided by such facility would be subject to regulation by
FERC.  Such  regulation  could  decrease  revenue,  increase  operating  costs,  and,  depending  upon  the  facility  in  question,  could  adversely  affect  our  financial
condition, results of operations and ability to make cash distributions to our unitholders. In addition, if any of our facilities were found to have provided services or
otherwise operated in violation of the NGA, NGPA or ICA, this could result in the imposition of substantial civil penalties, as well as a requirement to disgorge
revenues collected for such services in excess of the maximum rates established by FERC.

Natural  gas  gathering  and  intrastate  crude  oil  gathering  may  receive  greater  regulatory  scrutiny  at  the  state  level;  therefore,  these  operations  could  be
adversely affected should they become subject to the application of state regulation of rates and services. Our gathering operations could also be subject to safety
and operational  regulations  relating  to the design, construction,  testing,  operation,  replacement  and maintenance  of gathering  facilities.  We cannot  predict  what
effect, if any, such changes might have on our operations, but we could be required to incur additional capital expenditures and increased costs depending on future
legislative and regulatory changes.

We 
may 
incur 
significant 
costs 
and 
liabilities 
resulting 
from 
compliance 
with 
pipeline 
safety 
laws 
and 
regulations, 
pipeline 
integrity 
and 
other 
similar
programs
and
related

Certain  of our  pipeline  operations  are  subject  to  pipeline  safety  laws  and regulations.  PHMSA regulates  safety  requirements  for  the design,  construction,
maintenance  and  operation  of  jurisdictional  natural  gas  and  hazardous  liquids  pipeline  facilities.  All  of  our  interstate  and  intrastate  natural  gas  transportation
pipeline facilities are PHMSA jurisdictional and certain of our natural gas gathering, NGL, and crude oil pipeline facilities are PHMSA jurisdictional. Among other
things, these laws and regulations require pipeline operators to develop integrity management programs, including more frequent inspections and other measures
for pipelines located in “high consequence areas.” The regulations require operators, including us, to, among other things:

•

•

•

•

•

perform ongoing assessments of pipeline integrity;

develop a baseline plan to prioritize the assessment of a covered pipeline segment;

identify and characterize applicable threats that could impact a high consequence area;

improve data collection, integration, and analysis;

repair and remediate pipelines as necessary; and

implement preventive and mitigating action.

Failure to comply with PHMSA or comparable state pipeline safety regulations could result in a number of consequences which may have an adverse effect
on  our  operations.  We  incur  significant  costs  associated  with  our  compliance  with  existing  PHMSA  and  comparable  state  pipeline  regulations.  We  incurred
maintenance capital expenditures and operation and maintenance expenses of $54 million in 2018 and currently estimate that we will incur maintenance capital
expenditures  and  operation  and  maintenance  expenses  of  up  to  $65  million  in  2019  under  our  pipeline  safety  program,  including  costs  related  to  integrity
assessments and repairs, threat and risk analyses, implementing preventative and mitigative measures, and conducting activities to support

MAOP or MOP. We may incur significant cost associated with repair, remediation, preventive and mitigation measures associated with our integrity management
programs for pipelines that are not currently subject to regulation by PHMSA.

Changes  to  pipeline  safety  regulations  occur  frequently.  For  example,  PHMSA  is  expected  to  publish  finalized  regulations  in  2019,  for  both  gas  and
hazardous liquids pipelines, that will significantly extend and expand the reach of certain PHMSA integrity management requirements ( e.g. , period assessments,
leak detection and repairs) regardless of proximity to a high consequence area. The final rules will also impose new requirements for certain unregulated pipelines,
including gathering lines. The adoption of new regulations requiring more comprehensive or stringent safety standards could require us to install new or modified
safety  controls,  pursue  new  capital  projects,  or  conduct  maintenance  programs  on  an  accelerated  basis,  all  of  which  could  require  us  to  incur  increased  and
potentially significant operational costs.

Financial 
reform 
regulations 
under 
the 
Dodd-Frank 
Act 
could 
adversely 
affect 
our 
ability 
to 
use 
derivative 
instruments 
to 
hedge 
risks 
associated 
with 
our
business.

At  times,  we  may  hedge  all  or  a  portion  of  our  commodity  risk  and  our  interest  rate  risk.  The  federal  government  regulates  the  derivatives  markets  and
entities, including businesses like ours, that participate in those markets through the Dodd-Frank Wall Street Reform and Consumer Protection Act, or the Dodd-
Frank  Act,  which  requires  the  Commodity  Futures  Trading  Commission,  or  the  CFTC,  and  the  SEC  to  promulgate  rules  and  regulations  implementing  the
legislation. Under the CFTC’s regulations, we are subject to reporting and recordkeeping obligations for transactions involving non-financial swap transactions.
The  CFTC  initially  adopted  regulations  to  set  position  limits  for  certain  futures  and  option  contracts  in  the  major  energy  markets  and  for  swaps  that  are  their
economic  equivalents,  but  these  rules  were  successfully  challenged  in  federal  district  court  by  the  Securities  Industry  Financial  Markets  Association  and  the
International  Swaps  and  Derivatives  Association  and  largely  vacated  by  the  court.  In  December  2013,  the  CFTC  published  a  Notice  of  Proposed  Rulemaking
designed to implement new position limits regulation and in December 2016, the CFTC re-proposal position limits regulations. The ultimate form and timing of the
implementation of the regulatory regime affecting commodity derivatives remains uncertain.

The CFTC has imposed mandatory clearing requirements on certain categories of swaps, including certain interest rate swaps, but has exempted derivatives
intended  to  hedge  or  mitigate  commercial  risk  from  the  mandatory  swap  clearing  requirement,  where  a  counterparty  such  as  us  has  a  required  identification
number, is not a financial  entity  as defined  by the regulations,  and meets a minimum  asset test. Management  believes  our hedging transactions  qualify for this
“commercial  end-user”  exception.  The  Dodd-Frank  Act  may  also  require  us  to  comply  with  margin  requirements  in  connection  with  our  hedging  activities,
although the application of those provisions to us is uncertain at this time. The Dodd-Frank Act may also require the counterparties to our derivative instruments to
spin off some of their hedging activities to a separate entity, which may not be as creditworthy as the current counterparty.

The Dodd-Frank Act and related regulations could significantly increase the cost of derivatives contracts for our industry (including requirements  to post
collateral which could adversely affect our available liquidity), materially alter the terms of derivatives contracts, reduce the availability of derivatives to protect
against  risks  we  encounter,  reduce  our  ability  to  monetize  or  restructure  our  existing  derivatives  contracts,  and  increase  our  exposure  to  less  creditworthy
counterparties, particularly if we are unable to utilize the commercial end user exception with respect to certain of our hedging transactions. If we reduce our use of
hedging as a result of the legislation and regulations, our results of operations may become more volatile and our cash flows may be less predictable, which could
adversely affect our ability to plan for and fund capital expenditures and fund unitholder distributions. Finally, the legislation was intended, in part, to reduce the
volatility of crude oil and natural gas prices, which some legislators attributed to speculative trading in derivatives and commodity instruments related to crude oil
and natural gas. Our revenues could therefore be adversely affected if a consequence of the legislation and regulations is to lower commodity prices. Any of these
consequences could adversely affect our financial position, results of operations and our ability to make cash distributions to unitholders.

Risks Related to an Investment in Us

Our 
general 
partner 
and 
its 
affiliates, 
including 
CenterPoint 
Energy 
and 
OGE 
Energy, 
have 
conflicts 
of 
interest 
with 
us 
and 
limited 
duties 
to 
us 
and 
our
unitholders,
and
they
may
favor
their
own
interests
to
the
detriment
of
us
and
our
other
common
unitholders.

Affiliates of CenterPoint Energy and OGE Energy own and control our general partner and appoint all of the directors of our general partner. Some of the
directors of our general partner are appointed to represent CenterPoint Energy or OGE Energy and are also officers and/or directors of CenterPoint Energy or OGE
Energy, respectively. Although our general partner has a duty to manage us in a manner that is beneficial to us and our unitholders, the directors of our general
partner who are appointed to

47

 
 
 
Table of Contents

represent CenterPoint Energy or OGE Energy have a fiduciary duty to perform their obligations as directors in a manner that is beneficial to CenterPoint Energy or
OGE Energy,  respectively.  Conflicts  of  interest  will arise  between  CenterPoint  Energy,  OGE Energy and  our general  partner,  on the  one  hand, and us  and our
unitholders, on the other hand. In resolving these conflicts of interest, our general partner may favor its own interests and the interests of CenterPoint Energy and
OGE Energy over our interests and the interests of our unitholders. These conflicts include the following situations, among others:

• Neither the Partnership Agreement nor any other agreement requires CenterPoint Energy or OGE Energy to pursue a business strategy that favors us. The
directors and officers of CenterPoint Energy and OGE Energy have a fiduciary duty to make decisions in the best interests of the stockholders of their
respective companies, which may be contrary to our interests. CenterPoint Energy and OGE Energy may choose to shift the focus of their investment and
growth to areas not served by our assets. In addition, CenterPoint Energy is the holder of our Series A Preferred Units and may favor its interests in voting
in favor of actions relating to such units, including voting in favor of making distributions on such Series A Preferred Units even if no distributions are
made on the common units.

• Our  general  partner  is  allowed  to  take  into  account  the  interests  of  parties  other  than  us,  such  as  CenterPoint  Energy  and  OGE  Energy,  in  resolving

conflicts of interest.

• Some of the directors of our general partner are also officers and/or directors of CenterPoint Energy or OGE Energy and will owe fiduciary duties to their

respective companies. These individuals may also devote significant time to the business of CenterPoint Energy or OGE Energy, respectively.

• The Partnership Agreement replaces the fiduciary duties that would otherwise be owed to us by our general partner with contractual standards governing
its duties, limits  our general  partner’s  liabilities  and restricts  the remedies  available to our unitholders for actions that, without such limitations,  might
constitute breaches of fiduciary duty.

• Except in limited circumstances, our general partner has the power and authority to conduct our business without unitholder approval.

• Disputes may arise under our commercial agreements with CenterPoint Energy and OGE Energy.

• Our general partner determines the amount and timing of asset purchases and sales, borrowings, issuances of additional partnership units and the creation,

reduction or increase of cash reserves, each of which can affect the amount of distributable cash flow.

• Our general partner determines the amount and timing of any capital expenditures and whether a capital expenditure is classified as a maintenance capital
expenditure,  which  reduces  operating  surplus,  or  an  expansion  or  investment  capital  expenditure,  which  does  not  reduce  operating  surplus.  This
determination can affect the amount of cash that is distributed to our unitholders.

• Our general partner determines which costs incurred by it and its affiliates are reimbursable by us.

• Our general partner may cause us to borrow funds in order to permit the payment of cash distributions, even if the purpose or effect of the borrowing is to

make incentive distributions.

• The Partnership Agreement permits us to classify up to $300 million as operating surplus, even if it is generated from asset sales, non-working capital
borrowings or other sources that would otherwise constitute capital surplus. This cash may be used to fund distributions to our general partner in respect
of the incentive distribution rights.

• The Partnership Agreement does not prohibit our general partner from causing us to pay it or its affiliates for any services rendered to us or entering into

additional contractual arrangements with any of these entities on our behalf.

• Our general partner intends to limit its liability regarding our contractual and other obligations.

• Our general partner may exercise its right to call and purchase all of the common units not owned by it and its affiliates if they own more than 90% of the
common units. If our general partner and its affiliates reduce their ownership percentage to below 70% of the outstanding units, the ownership threshold
to exercise the call right will be permanently reduced to 80% .

• Our general partner controls the enforcement of the obligations that it and its affiliates owe to us.

• Our general partner decides whether to retain separate counsel, accountants or others to perform services for us.

• Our general partner may transfer its incentive distribution rights without unitholder approval.

• Our general partner may elect to cause us to issue common units to it in connection with a resetting of the target distribution levels related to our general
partner’s  incentive  distribution  rights  without  the  approval  of  the  conflicts  committee  of  the  Board  of  Directors  or  our  unitholders.  This  election  may
result in lower distributions to our common unitholders in certain situations.

If
a
unitholder
is
not
an
Eligible
Holder,
the
unitholder’s
common
units
may
be
subject
to
redemption.

Our  Partnership  Agreement  includes  certain  requirements  regarding  those  investors  who  may  own  our  common  and  preferred  units.  Eligible  Holders  are
limited partners whose (i) federal income tax status is not reasonably likely to have a material adverse effect on the rates that can be charged by us on assets that
are subject to regulation by FERC or an analogous regulatory body and (ii) nationality, citizenship or other related status would not create a substantial risk of
cancellation  or  forfeiture  of  any  property  in  which  we  have  an  interest,  in  each  case  as  determined  by  our  general  partner  with  the  advice  of  counsel.  If  the
unitholder is not an Eligible Holder, in certain circumstances as set forth in our Partnership Agreement, the unitholder’s units may be redeemed by us at the then-
current market price. The redemption price will be paid in cash or by delivery of a promissory note, as determined by our general partner.

Our
Partnership
Agreement
requires
that
we
distribute
all
of
our
available
cash,
which
could
limit
our
ability
to
grow
and
make
acquisitions.

Our Partnership Agreement requires that we distribute all of our available cash to our unitholders and will rely primarily upon external financing sources,
including commercial borrowings and the issuance of debt and equity securities, to fund our acquisitions and expansion capital expenditures. As a result, to the
extent  we  are  unable  to  finance  growth  externally,  our  cash  distribution  policy  will  significantly  impair  our  ability  to  grow.  For  further  information  related  to
distributions of available cash, please see Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

In addition, because we are required to distribute all of our available cash, our growth may not be as fast as that of businesses that reinvest their available
cash to expand ongoing operations. To the extent we issue additional units in connection with any acquisitions or expansion capital expenditures, the payment of
distributions on those additional units may increase the risk that we will be unable to maintain or increase our per unit distribution level. There are no limitations in
our  Partnership  Agreement  or  in  our  credit  facility  that  limit  our  ability  to  issue  additional  units,  including  units  ranking  senior  to  the  common  units.  The
incurrence of additional commercial borrowings or other debt to finance our growth strategy would result in increased interest expense, which in turn may impact
the available cash that we have to distribute to our unitholders.

Any
reductions
in
our
credit
ratings
could
increase
our
financing
costs
and
the
cost
of
maintaining
certain
contractual
relationships.

We cannot assure you that our credit ratings will remain in effect for any given period of time or that a rating will not be lowered or withdrawn entirely by a
rating agency if, in its judgment, circumstances warrant. If any of our credit ratings are below investment grade, we may have higher future borrowing costs and we
or our subsidiaries may be required to post cash collateral or letters of credit under certain contractual agreements. If cash collateral requirements were to occur at a
time when we were experiencing significant working capital requirements or otherwise lacked liquidity, our financial position, results of operations and ability to
make cash distributions to unitholders could be adversely affected.

The
credit
and
business
risk
profiles
and
the
business
plans
of
our
sponsors
could
adversely
affect
our
credit
ratings
and
profile.

The  credit  and  business  risk  profiles  and  the  business  plans  of  our  sponsors  may  be  factors  in  credit  evaluations  of  us  because,  through  their  indirect
ownership of our general partner, they can influence our business activities, including our cash distribution strategy, acquisition strategy, and business risk profile.
The financial conditions of CenterPoint Energy and OGE Energy, including the degree of their financial leverage and their dependence on cash flows from us, as
well as their business plans with respect to their investment in us, may be considered by credit rating agencies in their assessment of our credit ratings and profile.

CenterPoint  Energy  and  OGE  Energy,  which  indirectly  own  our  general  partner,  have  indebtedness  outstanding  and  are  partially  dependent  on  the  cash
distributions from their general partner and limited partner interests in us to service such indebtedness and pay dividends on their common stock. Any distributions
by us to such entities will be made only after satisfying our then-current obligations to our creditors. Our credit ratings and business risk profile could be adversely
affected if the ratings and risk profiles of the entities that control our general partner were viewed as substantially lower or riskier than ours.

Our
Partnership
Agreement
replaces
our
general
partner’s
fiduciary
duties
to
holders
of
our
common
units
with
contractual
standards
governing
its
duties.

Our Partnership Agreement contains provisions that eliminate the fiduciary standards to which our general partner would otherwise be held by state fiduciary
duty law and replaces  those duties with several  different  contractual  standards.  For example,  our Partnership  Agreement  permits  our general  partner  to make  a
number  of  decisions  in  its  individual  capacity,  as  opposed  to  in  its  capacity  as  our  general  partner,  free  of  any  duties  to  us  and  our  unitholders  other  than  the
implied contractual covenant of good

49

 
 
 
 
 
 
 
 
Table of Contents

faith and fair dealing, which means that a court will enforce the reasonable expectations of the partners where the language in the Partnership Agreement does not
provide for a clear course of action. This provision entitles our general partner to consider only the interests and factors that it desires and relieves it of any duty or
obligation to give any consideration to any interest of, or factors affecting, us, our affiliates or our limited partners. Examples of decisions that our general partner
may make in its individual capacity include:

•

•

•

•

•

•

how to allocate corporate opportunities among us and its other affiliates;

whether to exercise its limited call right;

whether to seek approval of the resolution of a conflict of interest by the conflicts committee of the Board of Directors;

whether to elect to reset target distribution levels;

whether to transfer the incentive distribution rights to a third party; and

whether or not to consent to any merger or consolidation of the Partnership or amendment to the Partnership Agreement.

By  purchasing  a  common  unit,  a  common  unitholder  agrees  to  become  bound  by  the  provisions  in  the  Partnership  Agreement,  including  the  provisions

discussed above.

Our 
Partnership 
Agreement 
restricts 
the 
remedies 
available 
to 
holders 
of 
our 
common 
units 
for 
actions 
taken 
by 
our 
general 
partner 
that 
might 
otherwise
constitute
breaches
of
fiduciary
duty.

Our  Partnership  Agreement  contains  provisions  that  restrict  the  remedies  available  to  unitholders  for  actions  taken  by  our  general  partner  that  might

otherwise constitute breaches of fiduciary duty under state fiduciary duty law. For example, our Partnership Agreement provides that:

•

•

•

•

whenever our general partner, the Board of Directors or any committee thereof (including the conflicts committee) makes a determination or takes, or
declines to take, any other action in their respective capacities, our general partner, the Board of Directors and any committee thereof (including the
conflicts committee), as applicable, is required to make such determination, or take or decline to take such other action, in good faith, meaning that it
subjectively believed that the decision was in the best interests of the Partnership, and, except as specifically provided by our Partnership Agreement,
will not be subject to any other or different standard imposed by our Partnership Agreement, Delaware law, or any other law, rule or regulation, or at
equity;

our general partner will not have any liability to us or our unitholders for decisions made in its capacity as a general partner so long as such decisions
are made in good faith;

our general partner and its officers and directors will not be liable for monetary damages to us or our limited partners resulting from any act or omission
unless  there  has  been  a  final  and  non-appealable  judgment  entered  by  a  court  of  competent  jurisdiction  determining  that  our  general  partner  or  its
officers and directors, as the case may be, acted in bad faith or engaged in fraud or willful misconduct or, in the case of a criminal matter, acted with
knowledge that the conduct was criminal; and

our  general  partner  will  not  be  in  breach  of  its  obligations  under  the  Partnership  Agreement  (including  any  duties  to  us  or  our  unitholders)  if  a
transaction with an affiliate or the resolution of a conflict of interest is:

•

•

•

•

approved by the conflicts committee of the Board of Directors, although our general partner is not obligated to seek such approval;

approved  by  the  vote  of  a  majority  of  the  outstanding  common  units,  excluding  any  common  units  owned  by  our  general  partner  and  its
affiliates;

determined by the Board of Directors to be on terms no less favorable to us than those generally being provided to or available from unrelated
third parties; or

determined  by  the  Board  of  Directors  to  be  fair  and  reasonable  to  us,  taking  into  account  the  totality  of  the  relationships  among  the  parties
involved, including other transactions that may be particularly favorable or advantageous to us.

In  connection  with  a  situation  involving  a  transaction  with  an  affiliate  or  a  conflict  of  interest,  any  determination  by  our  general  partner  or  the  conflicts
committee  must  be  made  in  good  faith.  If  an  affiliate  transaction  or  the  resolution  of  a  conflict  of  interest  is  not  approved  by  our  common  unitholders  or  the
conflicts committee and the Board of Directors determines that the resolution or course of action taken with respect to the affiliate transaction or conflict of interest
satisfies either of the standards set forth in the third and fourth sub-bullets above, then it will be presumed that, in making its decision, the Board of Directors

50

 
Table of Contents

acted in good faith, and in any proceeding brought by or on behalf of any limited partner or the Partnership challenging such determination, the person bringing or
prosecuting such proceeding will have the burden of overcoming such presumption.

Our
general 
partner 
may
elect 
to 
cause 
us
to 
issue
common 
units
to 
it 
in 
connection 
with
a
resetting 
of 
the 
minimum 
quarterly 
distribution 
and
the 
target
distribution
levels
related
to
our
general
partner’s
incentive
distribution
rights
without
the
approval
of
the
conflicts
committee
of
our
general
partner
or
our
unitholders.
This
may
result
in
lower
distributions
to
our
common
unitholders
in
certain
situations.

Our  general  partner  has  the  right,  if  it  has  received  incentive  distributions  at  the  highest  level  to  which  it  is  entitled  (50%)  for  each  of  the  prior  four
consecutive fiscal quarters and the amount of each such distribution did not exceed the adjusted operating surplus for such quarter, respectively, to reset the initial
minimum  quarterly  distribution  and  cash  target  distribution  levels  at  higher  levels  based  on  the  average  cash  distribution  amount  per  common  unit  for  the  two
fiscal quarters prior to the exercise of the reset election. Following a reset election by our general partner, the minimum quarterly distribution amount will be reset
to an amount equal to the average cash distribution amount per common unit for the two fiscal quarters immediately preceding the reset election (such amount is
referred  to  as  the  reset  minimum  quarterly  distribution)  and  the  target  distribution  levels  will  be  reset  to  correspondingly  higher  levels  based  on  percentage
increases above the reset minimum quarterly distribution amount.

We  anticipate  that  our  general  partner  would  exercise  this  reset  right  in  order  to  facilitate  acquisitions  or  internal  growth  projects  that  would  not  be
sufficiently  accretive  to  cash  distributions  per  common  unit  without  such  conversion;  however,  it  is  possible  that  our  general  partner  could  exercise  this  reset
election  at a time when we are experiencing  declines  in our aggregate  cash distributions  or at a time  when our general  partner  expects that  we will experience
declines  in  our  aggregate  cash  distributions  in  the  foreseeable  future.  In  such  situations,  our  general  partner  may  be  experiencing,  or  may  be  expected  to
experience, declines in the cash distributions it receives related to its incentive distribution rights and may therefore desire to be issued our common units, which
are entitled to specified priorities with respect to our distributions and which therefore may be more advantageous for the general partner to own in lieu of the right
to receive incentive distribution payments based on target distribution levels that are less certain to be achieved in the then-current business environment. This risk
could be elevated if our incentive distribution rights have been transferred to a third party. Our general partner has the right to transfer the incentive distribution
rights at any time, in whole or in part, and any transferee holding a majority of the incentive distribution rights shall have the same rights as our general partner
with  respect  to  resetting  target  distributions.  As  a  result,  a  reset  election  may  cause  our  common  unitholders  to  experience  dilution  in  the  amount  of  cash
distributions  that  they  would  have  otherwise  received  had  we  not  issued  new  common  units  to  our  general  partner  in  connection  with  resetting  the  target
distribution levels related to our general partner incentive distribution rights.

Holders
of
our
common
units
have
limited
voting
rights
and
are
not
entitled
to
elect
our
general
partner
or
its
directors.

Unlike the holders of common stock in a corporation, unitholders have only limited voting rights on matters affecting our business and, therefore, limited
ability to influence management’s decisions regarding our business. Unitholders have no right to elect our general partner or its Board of Directors on an annual or
other continuing basis. Because CenterPoint Energy and OGE Energy collectively indirectly own 100% of our general partner, the Board of Directors has been,
and,  as  long  as  CenterPoint  Energy  and  OGE  Energy  own  100%  of  our  general  partner,  will  continue  to  be,  chosen  by  CenterPoint  Energy  and  OGE  Energy.
Furthermore, if the unitholders were dissatisfied with the performance of our general partner, they will have little ability to remove our general partner. Please see
“—Even if holders of our common units are dissatisfied, they will not be able to remove our general partner without its consent.” As a result of these limitations,
the price at which the common units will trade could be diminished because of the absence or reduction of a takeover premium in the trading price. Our Partnership
Agreement also contains provisions limiting the ability of unitholders to call meetings or to acquire information about our operations, as well as other provisions
limiting the unitholders’ ability to influence the manner or direction of management.

Even
if
holders
of
our
common
units
are
dissatisfied,
they
will
not
be
able
to
remove
our
general
partner
without
its
consent.

The  unitholders  are  unable  to  remove  our  general  partner  without  its  consent  because  affiliates  of  our  general  partner  own  sufficient  units  to  be  able  to
prevent its removal. The vote of the holders of at least 75% of all outstanding units voting together as a single class is required to remove our general partner. As of
February 1, 2019 , affiliates of our general partner owned 79.6% of our aggregate outstanding common units.

Our
Partnership
Agreement
restricts
the
voting
rights
of
unitholders
owning
20%
or
more
of
our
common
units.

Unitholders’ voting rights are further restricted  by a provision of our Partnership Agreement providing that any units held by a person that owns 20% or
more  of  any  class  of  units  then  outstanding,  other  than  our  general  partner,  its  affiliates,  their  transferees  and  persons  who  acquired  such  units  with  the  prior
approval of the Board of Directors, cannot vote on any matter.

Our
general
partner’s
interest
in
us
and
control
of
our
general
partner
may
be
transferred
to
a
third
party
without
unitholder
consent.

Our general partner may transfer its general partner interest to a third party in a merger or in a sale of all or substantially all of its assets without the consent
of our unitholders. Our Partnership Agreement does not restrict the ability of the owners of our general partner from transferring all or a portion of their respective
limited liability company interest in our general partner to a third party. The new owners of our general partner would then be in a position to replace the Board of
Directors and officers of our general partner with its own choices and thereby influence the decisions taken by the Board of Directors and officers.

The
incentive
distribution
rights
of
our
general
partner
may
be
transferred
to
a
third
party
without
unitholder
consent.

Our general partner may transfer its incentive distribution rights to a third party at any time without the consent of our unitholders. If our general partner
transfers its incentive distribution rights to a third party but retains its general partner interest, our general partner may not have the same incentive to grow the
Partnership and increase quarterly distributions to unitholders over time as it would if it had retained ownership of its incentive distribution rights.

We
may
issue
additional
units
without
your
approval,
which
would
dilute
your
existing
ownership
interests.

The  Partnership  Agreement  does  not  limit  the  number  of  additional  limited  partner  interests,  including  limited  partner  interests  that  rank  senior  to  the
common units, that we may issue at any time without the approval of our unitholders. The issuance by us of additional common units or other equity securities of
equal or senior rank will have the following effects:

•

•

•

•

•

•

our existing unitholders’ proportionate ownership interest in us will decrease;

the amount of distributable cash flow on each unit may decrease;

because the amount payable to holders of incentive distribution rights is based on a percentage of the total distributable cash flow, the distributions to
holders of incentive distribution rights will increase even if the per unit distribution on common units remains the same;

the ratio of taxable income to distributions may increase;

the relative voting strength of each previously outstanding unit may be diminished; and

the market price of the common units may decline.

In addition, upon a change of control or certain fundamental transactions, our Series A Preferred Units are convertible into common units at the option of the
holders of such units. If a substantial portion of the Series A Preferred Units were converted into common units, common unitholders could experience significant
dilution. In addition, if holders of such converted Series A Preferred Units were to dispose of a substantial portion of these common units in the public market,
whether in a single transaction or series of transactions, it could adversely affect the market price for our common units. In addition, these sales, or the possibility
that these sales may occur, could make it more difficult for us to sell our common units in the future.

Affiliates 
of 
our 
general 
partner 
may 
sell 
common 
units 
in 
the 
public 
or 
private 
markets, 
which 
could 
have

direction.

As of February 1, 2019 , CenterPoint Energy held 233,856,623 common units and 14,520,000 Series A Preferred Units, and OGE Energy held 110,982,805
common units. Our Series A Preferred Units are convertible into common units upon a change of control or certain fundamental transactions at the option of the
holders of such units. Both our common units held by CenterPoint Energy and OGE Energy, as well as our Series A Preferred Units held by CenterPoint Energy,
are subject to certain registration rights. In addition, i n the first quarter of 2016, CenterPoint Energy announced that it was evaluating strategic alternatives for its
investment in Enable. In the first quarter of 2018, CenterPoint Energy disclosed that it had decided not to pursue a sale or spin-off qualifying under Section 355 of
the U.S. Internal Revenue Code at that time and that, while a transaction for all of its interests in the Partnership was not viable at that time, it may pursue such a
transaction  if  it  becomes  viable  in  the  future.  CenterPoint  Energy  also  disclosed  that  it  may  reduce  its  investment  in  the  Partnership  through  a  sale  of  all  or  a
portion of the Partnership common units it owns in the public equity markets or otherwise, subject to certain limitations. While there can be no assurances that
these evaluations will result in any specific action, CenterPoint Energy’s disclosure, as well as any sales by CenterPoint Energy of the common units it holds in the
public  equity  markets,  could  have  an  adverse  impact  on  the  market  for  our  common  units,  including  our  ability  to  issue  equity  on  favorable  terms  to  fund  our
capital needs or at all. Any sale of our general partner by CenterPoint Energy or OGE Energy may impact our strategic direction, business or results of operations.

Our
general
partner
has
a
limited
call
right
that
may
require
our
unitholders
to
sell
their
units
at
an
undesirable
time
or
price.

If at any time our general partner and its affiliates own more than 90% of our common units, our general partner will have the right, which it may assign to
any of its affiliates or to us, but not the obligation, to acquire all, but not less than all, of the common units held by unaffiliated persons at a price not less than their
then-current  market  price,  as  calculated  pursuant  to  the  terms  of  the  Partnership  Agreement  .  If  our  general  partner  and  its  affiliates  reduce  their  ownership
percentage  to  below  70%  of  the  outstanding  units,  the  ownership  threshold  to  exercise  the  call  right  will  be  permanently  reduced  to  80%.  As  a  result,  our
unitholders may be required to sell their common units at an undesirable time or price and may not receive any positive return on their investment. Our unitholders
may  also  incur  a  tax  liability  upon  any  such  sale  of  their  units.  As  of  February  1,  2019  ,  affiliates  of  our  general  partner  owned  approximately  79.6% of our
outstanding common units. If we assume the conversion of our Series A Preferred Units using the closing price of our units as of February 1, 2019 , affiliates of our
general partner will then own 80.7% of our aggregate outstanding common units. Affiliates of our general partner may acquire additional common units from us in
connection with future transactions or through open-market or negotiated purchases.

Our
unitholders’
liability
may
not
be
limited
if
a
court
finds
that
unitholder
action
constitutes
control
of
our
business.

A  general  partner  of  a  partnership  generally  has  unlimited  liability  for  the  obligations  of  the  partnership,  except  for  those  contractual  obligations  of  the
partnership  that  are  expressly  made  without  recourse  to  the  general  partner.  The  Partnership  is  organized  under  Delaware  law,  and  we  conduct  business  in  a
number  of  other  states.  The  limitations  on  the  liability  of  holders  of  limited  partner  interests  for  the  obligations  of  a  limited  partnership  have  not  been  clearly
established in some of the other states in which we may do business. Our unitholders could be held liable for any and all of our obligations as if they were general
partners if a court or government agency were to determine that:

•

•

we were conducting business in a state but had not complied with that particular state’s partnership statute; or

a unitholder’s right to act with other unitholders to remove or replace our general partner, to approve some amendments to our Partnership Agreement
or to take other actions under our Partnership Agreement constitutes “control” of our business.

Our
Partnership
Agreement
designates
the
Court
of
Chancery
of
the
State
of
Delaware
as
the
exclusive
forum
for
certain
types
of
actions
and
proceedings
that
may
be
initiated
by
our
unitholders,
which
limits
our
unitholders’
ability
to
choose
the
judicial
forum
for
disputes
with
us
or
our
general
partner’s
directors,
officers
or
other
employees.

Our Partnership Agreement provides, that, with certain limited exceptions, the Court of Chancery of the State of Delaware is the exclusive forum for any
claims, suits, actions or proceedings (1) arising out of or relating in any way to our Partnership Agreement (including any claims, suits or actions to interpret, apply
or enforce the provisions of our Partnership Agreement or the duties, obligations or liabilities among our partners, or obligations or liabilities of our partners to us,
or  the  rights  or  powers  of,  or  restrictions  on,  our  partners  or  us),  (2)  brought  in  a  derivative  manner  on  our  behalf,  (3)  asserting  a  claim  of  breach  of  a  duty
(including  a  fiduciary  duty)  owed  by  any  of  our,  or  our  general  partner’s,  directors,  officers,  or  other  employees,  or  owed  by  our  general  partner,  to  us  or  our
partners,  (4)  asserting  a  claim  against  us  arising  pursuant  to  any  provision  of  the  Delaware  Revised  Uniform  Limited  Partnership  Act  or  (5)  asserting  a  claim
against us governed by the internal affairs doctrine. Any person or entity purchasing or otherwise acquiring any interest in our common units is deemed to have
received notice of and consented to the foregoing provisions. Although management believes this choice of forum provision benefits us by providing increased
consistency in the application of Delaware law in the types of lawsuits to which it applies, the provision may have the effect of discouraging lawsuits against us
and our general partner’s directors and officers. The enforceability of similar choice of forum provisions in other companies’ certificates of incorporation or similar
governing  documents  has  been  challenged  in  legal  proceedings  and  it  is  possible  that  in  connection  with  any  action  a  court  could  find  the  choice  of  forum
provisions  contained  in  our  Partnership  Agreement  to  be  inapplicable  or  unenforceable  in  such  action.  If  a  court  were  to  find  this  choice  of  forum  provision
inapplicable  to,  or  unenforceable  in  respect  of,  one  or  more  of  the  specified  types  of  actions  or  proceedings,  we  may  incur  additional  costs  associated  with
resolving such matters in other jurisdictions, which could adversely affect our financial position, results of operations and ability to make cash distributions to our
unitholders.

The
NYSE
does
not
require
a
publicly
traded
limited
partnership
like
us
to
comply
with
certain
of
its
corporate
governance
requirements.

Our common units are listed on the NYSE. Because we are a publicly traded limited partnership, the NYSE does not require us to have, and we do not intend
to have, a majority of independent directors on our Board of Directors, to establish a nominating and corporate governance committee, or to have a compensation
committee composed entirely of independent directors.

53

 
 
 
Table of Contents

Accordingly, unitholders will not have the same protections afforded to certain corporations that are subject to all of the NYSE corporate governance requirements.

Unitholders
may
have
liability
to
repay
distributions
that
were
wrongfully
distributed
to
them.

Under  certain  circumstances,  unitholders  may  have  to  repay  amounts  wrongfully  returned  or  distributed  to  them.  Under  Section  17-607  of  the  Delaware
Revised Uniform Limited Partnership Act, we may not make a distribution to our unitholders if the distribution would cause our liabilities to exceed the fair value
of our assets. Delaware law provides that for a period of three years from the date of the impermissible distribution, limited partners who received the distribution
and  who  knew  at  the  time  of  the  distribution  that  it  violated  Delaware  law  will  be  liable  to  the  limited  partnership  for  the  distribution  amount.  Transferees  of
common units are liable for both the obligations of the transferor to make contributions to the Partnership that are known to the transferee at the time of transfer
and  for  unknown  obligations  if  the  liabilities  could  have  been  determined  from  the  Partnership  Agreement.  Neither  liabilities  to  partners  on  account  of  their
partnership interest nor liabilities that are non-recourse to the Partnership are counted for purposes of determining whether a distribution is permitted.

Our
general
partner
intends
to
limit
its
liability
regarding
our
obligations.

Our general partner intends to limit its liability under contractual arrangements so that the counterparties to such arrangements have recourse only against our
assets and not against our general partner or its assets. Our general partner may therefore cause us to incur indebtedness or other obligations that are non-recourse
to our general partner. Our Partnership Agreement permits our general partner to limit its liability, even if we could have obtained more favorable terms without
the limitation on liability. In addition, we are obligated to reimburse or indemnify our general partner to the extent that it incurs obligations on our behalf. Any
such reimbursement or indemnification payments would reduce the amount of cash otherwise available for distribution to our unitholders.

An
increase
in
interest
rates
could
adversely
impact
the
price
of
our
common
units,
our
ability
to
issue
equity
or
incur
debt
for
acquisitions
or
other
purposes
and
our
ability
to
make
cash
distributions
at
our
intended
levels.

Interest rates on future credit facilities and debt offerings could be higher than current levels, causing our financing costs to increase accordingly. As with
other  yield-oriented  securities,  the  market  price  of  our  common  units  is  impacted  by  the  level  of  our  cash  distributions  and  implied  distribution  yield.  The
distribution yield is often used by investors to compare and rank related yield-oriented securities for investment decision purposes. Therefore, changes in interest
rates may affect the yield requirements of investors who invest in our units, and a rising interest rate environment could have an adverse impact on the price of our
common units, our ability to issue additional equity to make acquisitions or for other purposes, our financial position, results of operations and our ability to make
cash distributions at our intended levels.

Our
Series
A
Preferred
Units
have
rights,
preferences
and
privileges
that
are
not
held
by,
and
are
preferential
to
the
rights
of,
holders
of
our
common
units.

Our Series A Preferred Units rank senior to all of our other classes or series of equity securities with respect to distribution rights and rights upon liquidation.
We cannot declare or pay a distribution to our common unitholders for any quarter unless full distributions have been or contemporaneously are being paid on all
outstanding  Series  A  Preferred  Units  for  such  quarter.  These  preferences  could  adversely  affect  the  market  price  for  our  common  units  or  could  make  it  more
difficult for us to sell our common units in the future.

Holders of the Series A Preferred Units will receive, on a non-cumulative basis and if and when declared by our general partner, a quarterly cash distribution,
subject to certain adjustments, equal to an annual rate of 10% on the stated liquidation preference from the date of original issue to, but not including, the five year
anniversary of the original issue date, and an annual rate of LIBOR plus a spread of 850 bps on the stated liquidation preference thereafter. In connection with
certain transfers of the Series A Preferred Units, the Series A Preferred Units will automatically convert into one or more new series of preferred units (the “other
preferred units”) on the later of the date of transfer or the second anniversary of the date of issue. The other preferred units will have the same terms as our Series A
Preferred Units except that unpaid distributions on the other preferred units will accrue from the date of their issuance on a cumulative basis until paid. Our Series
A  Preferred  Units  are  convertible  into  common  units  by  the  holders  of  such  units  in  certain  circumstances.  Payment  of  distributions  on  our  Series  A  Preferred
Units, or on the common units issued following the conversion of such Series A Preferred Units, could impact our liquidity and reduce the amount of cash flow
available for working capital, capital expenditures, growth opportunities, acquisitions, and other general partnership purposes. Our obligations to the holders of
Series  A Preferred  Units  could  also  limit  our  ability  to  obtain  additional  financing  or  increase  our  borrowing  costs,  which  could  have  an  adverse  effect  on our
financial condition.

Our
Series
A
Preferred
Units
contain
covenants
that
may
limit
our
business
flexibility.

Our Series A Preferred  Units contain covenants preventing us from taking certain  actions without the approval of the holders of 66 2⁄3% of the Series A
Preferred Units. The need to obtain the approval of holders of the Series A Preferred Units before taking these actions could impede our ability to take certain
actions that management or our board of directors may consider to be in the best interests of our unitholders. The affirmative vote of 66 2⁄3% of the outstanding
Series A Preferred Units, voting as a single class, is necessary to amend the Partnership Agreement in any manner that would or could reasonably be expected to
have  a  material  adverse  effect  on  the  rights,  preferences,  obligations  or  privileges  of  the  Series  A  Preferred  Units.  The  affirmative  vote  of  66  2⁄3%  of  the
outstanding Series A Preferred Units and any outstanding series of other preferred units, voting as a single class, is necessary to (A) create or issue certain party
securities with proceeds in an aggregate amount in excess of $700 million or create or issue any senior securities or (B) subject to our right to redeem the Series A
Preferred Units, approve certain fundamental transactions.

Our
Series
A
Preferred

are
required
to
be
redeemed
in
certain
circumstances
if
they
are
not

and
we
may
not
have
sufficient
funds
to
redeem
our
Series
A
Preferred
Units
if
we
are
required
to
do
so.

The holders of our Series A Preferred Units may request that we list those units for trading on the NYSE. If we are unable to list the Series A Preferred Units
in certain circumstances, we will be required to redeem the Series A Preferred Units. There can be no assurance that we would have sufficient financial resources
available to satisfy our obligation to redeem the Series A Preferred Units. In addition, mandatory redemption of our Series A Preferred Units could adversely affect
our financial position, results of operations and ability to make cash distributions to unitholders.

Tax Risks to Common Unitholders

Our
tax
treatment
depends
on
our
status
as
a
partnership
for
federal
income
tax
purposes.
If
the
IRS
were
to
treat
us
as
a
corporation
for
federal
income
tax
purposes,
which
would
subject
us
to
entity-level
taxation,
then
our
distributable
cash
flow
to
our
unitholders
would
be
substantially
reduced.

The anticipated after-tax economic benefit of an investment in the common units depends largely on our being treated as a partnership for federal income tax

purposes. We have not requested a ruling from the Internal Revenue Service, or IRS, regarding our qualification as a partnership for tax purposes.

Despite the fact that we are a limited partnership under Delaware law, it is possible in certain circumstances for a partnership such as ours to be treated as a
corporation for federal income tax purposes. A change in our business or a change in current law could cause us to be treated as a corporation for federal income
tax purposes or otherwise subject us to taxation as an entity.

If we were treated as a corporation for federal income tax purposes, we would pay federal income tax on our taxable income at the corporate tax rate, which
changed from 35% to 21% for tax years beginning after December 31, 2017 and would likely pay state and local income tax at varying rates. Distributions to our
unitholders would generally be taxed again as corporate dividends (to the extent of our current and accumulated earnings and profits), and no income, gains, losses,
deductions,  or  credits  would  flow  through  to  such  unitholders.  Because  a  tax  would  be  imposed  upon  us  as  a  corporation,  our  distributable  cash  flow  to  our
unitholders would be substantially reduced. Therefore, if we were treated as a corporation for federal income tax purposes there would be material reductions in the
anticipated cash flow and after-tax return to our unitholders, likely causing a substantial reduction in the value of our common units. This could adversely affect
our financial position, results of operations and ability to make cash distributions to unitholders.

Our  Partnership  Agreement  provides  that,  if  a  law  is  enacted  or  existing  law  is  modified  or  interpreted  in  a  manner  that  subjects  us  to  taxation  as  a
corporation  or  otherwise  subjects  us to  entity-level  taxation  for  federal,  state  or  local  income  tax  purposes,  the  minimum  quarterly  distribution  amount  and  the
target distribution amounts may be adjusted to reflect the impact of that law on us.

If
we
were
subjected
to
a
material
amount
of
additional
entity-level
taxation
by
individual
states,
it
would
reduce
our
distributable
cash
flow
to
our
unitholders.

Changes in current state law may subject us to additional entity-level taxation by individual states. Because of widespread state budget deficits and other
reasons,  several  states  are  evaluating  ways  to  subject  partnerships  to  entity-level  taxation  through  the  imposition  of  state  income,  franchise  and  other  forms  of
taxation. Imposition of such additional tax on us by a state will reduce

55

 
 
 
Table of Contents

the distributable cash flow. Our Partnership Agreement provides that, if a law is enacted or an existing law is modified or interpreted in a manner that subjects us to
entity-level taxation, the minimum quarterly distribution amount and the target distribution amounts may be adjusted to reflect the impact of that law on us.

The 
tax 
treatment 
of 
publicly 
traded 
partnerships 
or 
an 
investment 
in 
our 
common 
units 
could 
be 
subject 
to 
potential 
legislative, 
judicial 
or 
administrative
changes
and
differing
interpretations
of
applicable
law,
possibly
on
a
retroactive
basis.

The  present  federal  income  tax  treatment  of  publicly  traded  partnerships,  including  us,  or  an  investment  in  our  common  units  may  be  modified  by
administrative, legislative or judicial interpretation at any time. From time to time, members of the U.S. Congress propose and consider substantive changes to the
existing federal income tax laws that affect publicly traded partnerships. Although there is no current legislative proposal, a prior legislative proposal would have
eliminated  the  qualifying  income  exception  to  the  treatment  of  all  publicly-traded  partnerships  as  corporations  upon  which  we  rely  for  our  treatment  as  a
partnership for federal income tax purposes.

Any modification to the federal income tax laws and interpretations thereof could make it more difficult or impossible to meet the exception for us to be
treated as a partnership for U.S. federal income tax purposes. We are unable to predict whether any such changes will ultimately be enacted, but it is possible that a
change in law could affect us and may, if enacted, be applied retroactively. Any such changes could negatively impact the value of an investment in our common
units. You are urged to consult with your own tax advisor with respect to the status of regulatory or administrative developments and proposals and their potential
effect of your investment in our common units.

Our 
unitholders 
are 
required 
to 
pay 
income 
taxes 
on 
their 
share 
of 
our 
taxable 
income 
even 
if 
they 
do 
not 
receive 
any 
cash 
distributions 
from 
us. 
A
unitholder’s
share
of
our
taxable
income,
and
its
relationship
to
any
distributions
we
make,
may
be
affected
by
a
variety
of
factors,
including
our
economic
performance, 
transactions 
in 
which 
we
engage 
or 
changes 
in 
law 
and
may 
be 
substantially 
different 
from 
any
estimate 
we 
make 
in 
connection 
with
a 
unit
offering.

A unitholder’s allocable share of our taxable income will be taxable to the unitholder, which may require the unitholder to pay federal income taxes and, in
some cases, state and local income taxes, even if the unitholder receives cash distributions from us that are less than the actual tax liability that results from that
income or no cash distributions at all.

A unitholder’s share of our taxable income, and its relationship to any distributions we make, may be affected by a variety of factors, including our economic
performance,  which  may  be  affected  by  numerous  business,  economic,  regulatory,  legislative,  competitive  and  political  uncertainties  beyond  our  control,  and
certain transactions in which we might engage. For example, we may engage in transactions that produce substantial taxable income allocations to some or all of
our unitholders without a corresponding increase in cash distributions to our unitholders, such as a sale or exchange of assets, the proceeds of which are reinvested
in our business or used to reduce our debt, or an actual or deemed satisfaction of our indebtedness for an amount less than the adjusted issue price of the debt. The
ratio of a unitholder’s share of taxable income to the cash received by it may also be affected by changes in law. For instance, under the Tax Cuts and Jobs Act, for
taxable  years  beginning  after  2017  the  net  interest  expense  deductions  of  certain  business  entities,  including  us,  are  limited  to  30%  of  such  entity’s  “adjusted
taxable income,” which is generally taxable income with certain modifications. If the limit applies, a unitholder’s taxable income allocations will be more (or its
net loss allocations will be less) than would have been the case absent the limitation.

From time to time, in connection with an offering of our units, we may state an estimate of the ratio of federal taxable income to cash distributions that a
purchaser of units in that offering may receive in a given period. These estimates depend in part on factors that are unique to the offering with respect to which the
estimate is stated, so the expected ratio applicable to other units will be different, and in many cases less favorable, than these estimates. Moreover, even in the
case of units purchased in the offering to which the estimate relates, the estimate may be incorrect, due to the uncertainties described above, challenges by the IRS
to tax reporting positions which we adopt, or other factors. The actual ratio of taxable income to cash distributions could be higher or lower than expected, and any
differences could be material and could materially affect the value of the common units.

If
the
IRS
contests
the
federal
income
tax
positions
we
take,
the
market
for
our
common
units
may
be
adversely
impacted
and
the
cost
of
any
IRS
contest
would
likely
reduce
our
distributable
cash
flow
to
unitholders.

We have not requested a ruling from the IRS with respect to our treatment as a partnership for federal income tax purposes. The IRS may adopt positions that
differ from the conclusions of our counsel expressed in a prospectus or from the positions we take, and the IRS’s positions may ultimately be sustained. It may be
necessary to resort to administrative or court proceedings to sustain some or all of our counsel’s conclusions or the positions we take and such positions may not
ultimately be sustained. A court may not agree with some or all of our counsel’s conclusions or the positions we take. Any contest with the IRS, and the outcome
of any IRS contest, may have a materially adverse effect on the market for our common units and the price at which they

56

 
 
 
Table of Contents

trade. In addition, our costs of any contest with the IRS would be borne indirectly by our unitholders and our general partner because the costs would likely reduce
our distributable cash flow to our unitholders.

If
the
IRS
makes
audit
adjustments
to
our
income
tax
returns
for
tax
years
beginning
after
2017,
the
IRS
(and
some
states)
may
collect
any
resulting
taxes
(including
any
applicable
penalties
and
interest)
directly
from
us,
in
which
case
we
may
require
our
unitholders
and
former
unitholders
to
reimburse
us
for
such
taxes
(including
any
applicable
penalties
or
interest)
or,
if
we
are
required
to
bear
such
payment,
our
cash
available
for
distribution
to
our
unitholders
might
be
substantially
reduced.

Pursuant to the Bipartisan Budget Act of 2015, if the IRS makes audit adjustments to our income tax returns for tax years beginning after 2017, it may collect
any resulting taxes (including any applicable penalties and interest) directly from us. We will generally have the ability to shift any such tax liability to our general
partner and our unitholders in accordance with their interests in us during the year under audit, but there can be no assurance that such election will be practical,
permissible or effective under all circumstances, or that we will be able to (or choose to) effect corresponding shifts in state income or similar tax liability resulting
from the IRS adjustment in states in which we do business in the year under audit or in the adjustment year. If we make payments of taxes, penalties and interest
resulting  from  audit  adjustments,  we  may  require  our  unitholders  and  former  unitholders  to  reimburse  us  for  such  taxes  (including  any  applicable  penalties  or
interest)  or,  if we are  required  to bear  such payment,  our  cash  available  for  distribution  to our  unitholders  might  be  substantially  reduced.  In  addition,  because
payment would be due during the year in which the audit is completed, unitholders during that year would bear the burden of the adjustment even if they were not
unitholders during the audited taxable year.

In the event the IRS makes an audit adjustment to our income tax returns and we do not or cannot shift the liability to our unitholders in accordance with their
interests in us during the year under audit, we will generally have the ability to request that the IRS reduce the determined underpayment by the amount of any
suspended passive loss carryovers of specified unitholders (without any compensation from us to such unitholders). Such reduction, if approved by the IRS, will be
binding on any affected unitholders.

Tax
gain
or
loss
on
the
disposition
of
our
common
units
could
be
more
or
less
than
expected.

If any of our unitholders sells their common units, such unitholders must recognize a gain or loss for federal income tax purposes equal to the difference
between the amount realized and such unitholder’s tax basis in those common units. Because distributions in excess of such unitholder’s allocable share of our net
taxable income decrease such unitholder’s tax basis in such unitholder’s common units, the amount, if any, of such prior excess distributions with respect to the
common units such unitholder sells will, in effect, become taxable income if such unitholder sells such common units at a price greater than its tax basis in those
common units, even if the price such unitholder receives is less than its original cost. Furthermore, a substantial portion of the amount realized on any sale or other
disposition  of  such  unitholder’s  common  units,  whether  or  not  representing  gain,  may  be  taxed  as  ordinary  income  due  to  potential  recapture  items,  including
depreciation recapture. In addition, because the amount realized includes a unitholder’s share of our nonrecourse liabilities, if a unitholder sells its common units, it
may incur a tax liability in excess of the amount of cash it receives from the sale. Thus, a unitholder may recognize both ordinary income and capital loss from the
sale of units if the amount realized on a sale of such units is less than the unitholder's adjusted basis in the units. Net capital loss may only offset capital gains and,
in  the  case  of  individuals,  up  to  $3,000  of  ordinary  income  per  year.  In  the  taxable  period  in  which  a  unitholder  sells  its  common  units,  such  unitholder  may
recognize ordinary income from our allocations of income and gain to such unitholder prior to the sale and from recapture items that generally cannot be offset by
any capital loss recognized upon the sale of units.

issues
from
owning
our
common
units
that
may
result
in
adverse
tax
consequences
to
them.

Investment in our common units by tax-exempt entities, such as employee benefit plans and individual retirement accounts (known as IRAs), and non-U.S.
persons raises issues unique to them. For example, virtually all of our income allocated to organizations that are exempt from federal income tax, including IRAs
and other retirement plans, will be unrelated business taxable income (UBTI) and will be taxable to the exempt organization as UBTI on the exempt organization’s
tax return  in the year  the exempt  organization  is allocated  the  income.  Further,  with  respect  to taxable  years  beginning  after  December  31, 2017, a tax-exempt
entity with more than one unrelated trade or business (including by attribution from investment in a partnership such as ours) is required to compute the UBTI of
such tax-exempt entity separately with respect to each trade or business (including for purposes of determining any net operating loss deduction). As a result, for
years beginning after December 31, 2017, it may not be possible for tax-exempt entities to utilize losses from an investment in our partnership to offset unrelated
business taxable income from another unrelated trade or business and vice versa. Tax-exempt entities should consult a tax advisor before investing in our common
units.

Distributions to non-U.S. persons will be reduced by withholding taxes at the highest applicable effective tax rate, and non-U.S. persons will be required to

file U.S. federal income tax returns and pay tax on their share of our taxable income.

Under the Tax Cuts and Jobs Act, if a unitholder sells or otherwise disposes of a common unit, the transferee is required to withhold 10.0% of the amount
realized by the transferor unless the transferor certifies that it is not a foreign person, and we are required to deduct and withhold from the transferee amounts that
should have been withheld by the transferee but were not withheld. However, the Department of the Treasury and the IRS have determined that this withholding
requirement should not apply to any disposition of a publicly traded interest in a publicly traded partnership (such as us) until regulations or other guidance have
been  issued  clarifying  the  application  of  this  withholding  requirement  to  dispositions  of  interests  in  publicly  traded  partnerships.  Accordingly,  while  this  new
withholding requirement does not currently apply to interests in us, there can be no assurance that such requirement will not apply in the future.

If you are a tax-exempt entity or a non-U.S. person, you should consult a tax advisor before investing in our common units.

We 
treat 
each 
holder 
of 
our 
common 
units 
as 
having 
the 
same 
tax 
benefits 
without 
regard 
to 
the 
actual 
common 
units 
held. 
The 
IRS 
may 
challenge 
this
treatment,
which
could
adversely
affect
the
value
of
the
common
units.

Because  we  cannot  match  transferors  and  transferees  of  common  units  and  because  of  other  reasons,  we  have  adopted  depreciation  and  amortization
positions that may not conform to all aspects of existing Treasury Regulations. A successful IRS challenge to those positions could adversely affect the amount of
tax benefits available to our unitholders. A successful IRS challenge also could affect the timing of these tax benefits or the amount of gain from a unitholder’s sale
of common units and could have a negative impact on the value of our common units or result in audit adjustments to such unitholder’s tax returns.

We
generally
prorate
our
items
of
income,
gain,
loss
and
deduction
for
U.S.
federal
income
tax
purposes
between
transferors
and
transferees
of
our
units
each
month
based
upon
the
ownership
of
our
units
on
the
first
day
of
each
month,
instead
of
on
the
basis
of
the
date
a
particular
unit
is
transferred.
The
IRS
may
challenge
this
treatment,
which
could
change
the
allocation
of
items
of
income,
gain,
loss
and
deduction
among
our
unitholders.

We generally prorate our items of income, gain, loss and deduction for U.S. federal income tax purposes between transferors and transferees of our units
each  month  based  upon  the  ownership  of  our  units  on  the  first  day  of  each  month,  instead  of  on  the  basis  of  the  date  a  particular  unit  is  transferred.  The  U.S.
Department of the Treasury adopted final Treasury Regulations allowing a similar monthly simplifying convention for taxable years beginning on or after August
3, 2015. However, such final regulations do not specifically authorize the use of the proration method we have adopted. If the IRS were to challenge our proration
method or new Treasury regulations were issued, we may be required to change the allocation of items of income, gain, loss and deduction among our unitholders.

A
unitholder
whose
common
units
are
loaned
to
a
“short
seller”
to
cover
a
short
sale
of
common
units
may
be
considered
as
having
disposed
of
those
common
units.
If
so,
such
unitholder
would
no
longer
be
treated
for
federal
income
tax
purposes
as
a
partner
with
respect
to
those
common
units
during
the
period
of
the
loan
and
may
recognize
gain
or
loss
from
the
disposition.

Because a unitholder whose common units are loaned to a “short seller” to cover a short sale of common units may be considered as having disposed of the
loaned common units, such unitholder may no longer be treated for federal income tax purposes as a partner with respect to those common units during the period
of the loan to the short seller and may recognize gain or loss from such disposition. Moreover, during the period of the loan to the short seller, any of our income,
gain, loss or deduction with respect to those common units may not be reportable by the unitholder and any cash distributions received by the unitholder as to those
common units could be fully taxable as ordinary income. Therefore, our unitholders desiring to assure their status as partners and avoid the risk of gain recognition
from a loan to a short seller are urged to consult a tax advisor to discuss whether it is advisable to modify any applicable brokerage account agreements to prohibit
their brokers from loaning their common units.

We
have
adopted
certain
valuation
methodologies
and
monthly
conventions
for
U.S.
federal
income
tax
purposes
that
may
result
in
a
shift
of
income,
gain,
loss
and
deduction
between
our
general
partner
and
our
unitholders.
The
IRS
may
challenge
this
treatment,
which
could
adversely
affect
the
value
of
the
common
units.

When we issue additional units, or engage in certain other transactions, we will determine the fair market value of our assets and allocate any unrealized gain
or loss attributable to our assets to the capital accounts of our unitholders and our general partner. Our methodology may be viewed as understating the value of our
assets. In that case, there may be a shift of income, gain, loss and deduction between certain unitholders and our general partner, which may be unfavorable to such
unitholders.  Moreover,  under  our  valuation  methods,  subsequent  purchasers  of  common  units  may  have  a  greater  portion  of  their  Internal  Revenue  Code
Section 743(b) adjustment allocated to our tangible assets and a lesser portion allocated to our intangible assets. The IRS may

58

 
 
 
 
 
 
Table of Contents

challenge our valuation methods, or our allocation of the Section 743(b) adjustment attributable to our tangible and intangible assets, and allocations of taxable
income, gain, loss and deduction between our general partner and certain of our unitholders.

A successful IRS challenge to these methods or allocations could adversely affect the amount of taxable income or loss being allocated to our unitholders. It
also could affect the amount of taxable gain from our unitholders’ sale of common units and could have a negative impact on the value of the common units or
result in audit adjustments to our unitholders’ tax returns without the benefit of additional deductions.

As
a
result
of
investing
in
our
common
units,
our
unitholders
will
likely
be
subject
to
state
and
local
taxes
and
return
filing
requirements
in
jurisdictions
where
we
operate
or
own
or
acquire
properties.

In addition to federal income taxes, our unitholders will likely be subject to other taxes, including state and local taxes, unincorporated business taxes and
estate, inheritance or intangible taxes that are imposed by the various jurisdictions in which we conduct business or own property now or in the future, even if they
do not live in any of those jurisdictions. Our unitholders will likely be required to file state and local income tax returns and pay state and local income taxes in
some or all of these various jurisdictions. Further, our unitholders may be subject to penalties for failure to comply with those requirements. We currently own
property  and conduct  business in a number of states,  most of which currently  impose  a personal  income tax on individuals,  and most of which also impose  an
income or similar tax on corporations and certain other entities. As we make acquisitions or expand our business, we may own property or conduct business in
additional  states  that  impose  an  income  tax  or  similar  tax.  In  certain  states,  tax  losses  may  not  produce  a  tax  benefit  in  the  year  incurred  and  also  may  not  be
available to offset income in subsequent tax years. Some states may require us, or we may elect, to withhold a percentage of income from amounts to be distributed
to a unitholder who is not a resident of the state. Withholding, the amount of which may be greater or less than a particular unitholders’ income tax liability to the
state, generally does not relieve a nonresident unitholder from the obligation to file an income tax return. Amounts withheld may be treated as if distributed to
unitholders for purposes of determining the amounts distributed by us.

Compliance
with
and
changes
in
tax
laws
could
adversely
affect
our
performance.

We  are  subject  to  extensive  tax  laws  and  regulations,  including  federal  and  state  income  taxes  and  transactional  taxes  such  as  excise,  sales/use,  payroll,
franchise and ad valorem taxes. New tax laws and regulations and changes in existing tax laws and regulations are continuously being enacted that could result in
increased tax expenditures in the future. Many of these tax liabilities are subject to audits by the respective taxing authority. These audits may result in additional
taxes as well as interest and penalties.

Item 1B. Unresolved Staff Comments.

None.

Item 2. Properties

Our  material  properties  consist  of  our  principal  executive  offices,  gathering  systems,  processing  plants,  transportation  systems  and  storage  facilities.  Our
principal executive offices are located in approximately 162,053 square feet of leased office space at One Leadership Square, 211 North Robinson Avenue, Suite
150, Oklahoma City, Oklahoma 73102. For descriptions of the location and general character of our other material properties, please see Item 1. “Business—Our
Assets and Operations.”

Our processing plants are located on fee property, except for our Roger Mills plant which is located on leased property. Our other gathering, processing,
transportation,  and  storage  assets  are  located  on  property  that  we  have  the  right  to  use  under  easements,  leases,  licenses,  or  permits  granted  by  governmental
agencies, American Indian tribes, railroads, utilities, and other third parties. In some cases, title to our properties or other land rights may be subject to renewals,
require periodic payments, or be subject to revocation at the option of the grantor. For example, certain easements granted across American Indian allotted land to
which title is held in trust by the United States are subject to renewal, and certain licenses and permits granted by governmental agencies are subject to revocation
at the option of the grantor. In other cases, title to our property or other land rights may be subject to encumbrances, restrictions, or imperfections. For example, our
title in certain instances may be subject to liens that are not subordinated to our rights, and our title in certain locations may reflect names of predecessors until we
have made the appropriate  filings. We believe  that we generally  have sufficient  title  to our properties  and other land rights necessary to operate  our assets and
conduct  our  business,  subject  to  such  renewals,  period  payments,  revocation  rights,  restrictions,  encumbrances  and  imperfections  that  do  not  materially  either
detract from the value of our assets or interfere with the conduct of our business.

Item 3. Legal Proceedings

In the normal course of business, we are confronted with issues or events that may result in a contingent liability. These generally relate to lawsuits or claims
made by third parties, including governmental agencies. When appropriate, management consults with legal counsel and other appropriate experts to assess the
claim. If, in management’s opinion, we have incurred a probable loss as set forth by GAAP, an estimate is made of the loss and the appropriate accounting entries
are reflected in our Consolidated Financial Statements. At the present time, based on currently available information, management believes that any reasonably
possible losses in excess of accrued amounts arising out of pending or threatened lawsuits or claims would not be quantitatively material to our financial statements
and would not have a material adverse effect on our consolidated financial position, results of operations or cash flows.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The  following  discussion  and  analysis  of  our  financial  condition  and  results  of  operations  should  be  read  in  conjunction  with  our  consolidated  financial

statements and notes included in this report.

Overview

We are a Delaware limited partnership formed in May 2013 to own, operate and develop strategically located midstream assets. We completed our IPO in
April 2014, and we are traded on the NYSE under the symbol “ENBL.” We were formed by CenterPoint Energy, OGE Energy and ArcLight. Our general partner
is owned by CenterPoint Energy and OGE Energy.

Our Operations

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  gathering  and  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  gathering  and  processing  assets  include  approximately  13,400  miles  of  natural  gas  gathering  pipelines,  15  natural  gas  processing  plants  with
approximately 2.6 Bcf/d of processing capacity and approximately 1,160,900 horsepower of compression as of December 31, 2018 in the Anadarko, Arkoma and
Ark-La-Tex Basins. In addition, our gathering and processing assets include approximately 150 miles of crude oil and condensate gathering pipelines (including
VPP) serving the Anadarko Basin, 175 miles of crude oil gathering pipelines and 150 miles of produced water gathering pipelines serving the Williston Basin.

Our transportation and storage assets include approximately 10,090 miles of natural gas intrastate and interstate transportation pipelines across nine states,
eight  natural  gas  storage  facilities  with  approximately  84.5  Bcf  of  storage  capacity  and  approximately  837,600  horsepower  of  compression.  As  part  of  these
transportation and storage assets, we own a 50% interest in, and provide field operations for, SESH, an approximately 290-mile interstate pipeline providing access
to the Southeast power generation market.

Items Affecting the Comparability of Our Financial Results

The  comparability  of  our  current  financial  condition  and  results  of  operations  with  our  historical  financial  conditions  and  results  of  operations  may  be

affected by the items described below.

Capitalization

On February 18, 2016, the Partnership completed the private placement of 14,520,000 Series A Preferred Units 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 accounted for 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. In connection with the private placement, Enable GP
adopted  the  Partnership’s  Third  Amended  and  Restated  Agreement  of  Limited  Partnership  on  February  18,  2016,  which,  among  other  things,  authorized  the
issuance of Series A Preferred Units. The Series A Preferred Units rank senior to the Partnership’s common units with respect to the payment of distributions and
the 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;  receive  on  a  non-
cumulative basis if and when declared by the general partner, a quarterly cash distribution, subject to certain adjustments, equal to an annual rate of 10% on the
stated liquidation preference from the date of original issue to, but not including, the five year anniversary of the original issue date and an annual rate of LIBOR
plus 850 bps on the stated liquidation preference thereafter.

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

63

 
Table of Contents

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.

On  May  12,  2017,  the  Partnership  entered  into  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. For the year ended  December 31, 2018 , the Partnership
issued 140,920 common units under the ATM Program, which generated proceeds of approximately $2 million (net of approximately $25,000 of commissions).
The proceeds were used for general partnership purposes. For the year ended December 31, 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 commissions).  The  Partnership  incurred  approximately
$345,000 of expenses associated with the filing of the registration statements for the ATM Program. The proceeds were used for general partnership purposes. As
of December 31, 2018 , $197 million of common units remained available for issuance through the ATM Program.

Financing

On July 31, 2015, the Partnership entered into a term loan agreement providing for an unsecured, three -year $450 million term loan agreement (2015 Term
Loan Agreement). In May 2018, the Partnership used a portion of the proceeds from the issuance of the 2028 Notes to repay all amounts outstanding under the
2015 Term Loan Agreement.

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.

On  April  6,  2018,  the  Partnership  amended  and  restated  its  Revolving  Credit  Facility.  As  amended  and  restated,  the  Revolving  Credit  Facility  is  a  $1.75
billion , 5-year senior unsecured revolving credit facility, which under certain circumstances may be increased from time to time up to an additional $875 million,
in aggregate. The Revolving Credit Facility is scheduled to mature on April 6, 2023.

On May 10, 2018, the Partnership  completed  the  public  offering  of  $800 million aggregate principal amount of its 4.950% Senior  Notes  due 2028 (2028
Notes). The Partnership received net proceeds of approximately $787 million . The proceeds were used for general partnership purposes, including to repay all
amounts outstanding under the 2015 Term Loan Agreement, as well as amounts outstanding under the commercial paper program.

Trends and Outlook

We  expect  our  business  to  continue  to  be  impacted  by  the  trends  affecting  our  industry  that  are  discussed  below.  Our  outlook  is  based  on  assumptions
regarding  the  impact  of  these  trends  that  we  have  developed  by  interpreting  the  information  currently  available  to  us.  If  our  assumptions  or  interpretation  of
available information prove to be incorrect, our future financial condition and results of operations may differ materially from our expectations.

Commodity
Price
Environment

Our  business  is  impacted  by  commodity  prices  which  have  declined  and  otherwise  experienced  significant  volatility  in  recent  years.  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  negatively  impacted  if
producers decrease drilling and production in those areas served. Both our gathering and processing segment and our transportation and storage segment can be
impacted by drilling and production. Our gathering and processing segment primarily serve producers, and many producers utilize the services provided by our
transportation and storage segment. A decrease in volumes will decrease the cash flows from our systems. In addition, our processing arrangements expose us to
commodity price fluctuations. 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.”

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 Risk — Commodity Price Risk.”

Commodity
Supply
and
Demand
Dynamics

Our long-term view is that natural gas and crude oil production in the United States will increase. There has been a fundamental shift in the United States
natural  gas  and  crude  oil  production  towards  tight  gas  formations  and  shale  plays.  Advancements  in  technology  have  allowed  producers  to  efficiently  extract
natural  gas  and  crude  oil  from  these  formations  and  plays.  As  a  result,  the  proven  reserves  of  natural  gas  and  crude  oil  in  the  United  States  have  significantly
increased.

Natural  gas  continues  to  be  a  critical  component  of  energy  demand  in  the  United  States.  Over  the  long  term,  management  believes  that  the  prospects  for
continued  natural  gas  demand  are  favorable  and  will  be  driven  by population  and  economic  growth,  as  well  as the  continued  displacement  of coal-fired  power
plants by natural gas-fired power plants due to the price of natural gas and stricter government environmental regulations on the mining and burning of coal. We
believe  that  increasing  consumption  of  natural  gas  over  the  long  term  in  these  sectors  will  continue  to  drive  demand  for  our  natural  gas  gathering,  processing,
transportation and storage services.

Capital
Market
Volatility

We  may  access  the  capital  markets  to  fund  our  expansion  capital  expenditures.  Historically,  unit  prices  of  midstream  master  limited  partnerships  have
experienced  periods  of  volatility.  In  addition,  because  our  common  units  are  yield-based  securities,  rising  market  interest  rates  could  impact  the  relative
attractiveness of our common units to investors. Further, fluctuations in energy and commodity prices can create volatility in our common unit prices, which could
impact  investor  appetite  for  our  common  units.  Volatility  in  energy  and  commodity  prices,  as  well  as  other  macro-economic  factors  could  impact  the  relative
attractiveness of our debt securities to investors. As a result of capital market volatility, we may be unable to issue equity securities or debt on satisfactory terms, or
at all, which may limit our ability to expand our operations or make future acquisitions. See Part I, Item 1A. “Risk Factors—Risks Related to Our Business.”

Regulatory
Compliance

The regulation of gathering and transmission pipelines, storage and related facilities by FERC and other federal and state regulatory agencies, including the
DOT,  has  a  significant  impact  on  our  business.  For  example,  the  DOT’s  Pipeline  and  Hazardous  Materials  Safety  Administration,  or  PHMSA,  has  established
pipeline  integrity  management  programs  that  require  more  frequent  inspections  of  pipeline  facilities  and  other  preventative  measures,  which  may  increase  our
compliance costs and increase the time it takes to obtain required permits. Additionally, increased regulation of oil and natural gas producers, including regulation
associated with hydraulic fracturing, could reduce regional supply of oil and natural gas and therefore throughput on our gathering systems. For more information,
see Item 1. “Business — Rate and Other Regulation.”

Measures We Use to Evaluate Results of Operations

We use a variety  of operational  and financial  measures  to evaluate  our results of operations  and our financial  condition and to manage our business. The
measures that we use to analyze our business include: (i) throughput volumes, (ii) operation and maintenance and general and administrative expenses, (iii) Gross
margin, (iv) Adjusted EBITDA, (v) Adjusted interest expense, (vi) DCF and (vii) Distribution coverage ratio.

Throughput
Volumes

Throughput  volume  is  operating  data.  The  volumes  of  natural  gas,  crude  oil,  condensate  and  produced  water  on  our  gathering  and  processing  and
transportation and storage systems depends significantly on the level of production from the basins served by our systems and the wells connected to our systems.
G athering and processing as well as transportation and storage can be impacted by the wells connected to our system because the customers for our gathering and
processing services are primarily producers, and many producers utilize our transportation and storage services. Aggregate production volumes are impacted by the
overall amount of drilling and completion activity, as production must be maintained or increased by new drilling or other activity, because the production rates of
wells decline over time. Producers’ willingness to engage in new drilling is determined by a number of factors, which include: the prevailing and projected prices
of  natural  gas,  NGLs  and  crude  oil;  the  cost  to  drill  and  operate  a  well;  the  availability  and  cost  of  capital;  technological  advances  in  drilling  and  production
techniques;  and  environmental  and  other  government  regulations.  We  generally  expect  the  level  of  drilling  to  positively  correlate  with  long-term  trends  in
commodity prices. Similarly, we generally expect the level of production to positively correlate with drilling activity.

To maintain and increase throughput volumes on our gathering and processing systems, we must compete to connect to new

65

Table of Contents

wells as production from existing wells declines. We actively monitor drilling activity in the areas served by our gathering and processing systems to pursue new
customers  and  new  wells.  To  maintain  and  increase  the  throughput  volumes  on  our  transportation  and  storage  systems,  we  must  compete  for  the  business  of
producers and other customers who have existing and new sources of supply in the basins served by our systems, and we must compete for the business of power
plants, LDCs, industrial end users and other customers who have existing and new sources of demand in the markets served by our systems.

We  actively  monitor  customer  activity  in  the  basins  and  markets  served  by  our  transportation  and  storage  systems  to  pursue  new  supply  and  demand
opportunities. In both gathering and processing and transportation and storage, we compete for customers based on service offerings, operating flexibility, receipt
and delivery points, available capacity and price.

Operation
and
Maintenance
and
General
and
Administrative
Expenses

Operation and Maintenance and General and Administrative Expenses is a GAAP financial measure. We seek to maximize the profitability of our operations
by  effectively  managing  operation  and  maintenance  and  general  and  administrative  expenses.  These  expenses  are  comprised  primarily  of  labor  expenses,  lease
costs, utility costs, insurance premiums, repair expenses and maintenance expenses. These labor expenses, lease costs, utility costs and insurance premiums have
remained relatively stable across periods in the current low inflation environment, but repair and maintenance expense can fluctuate from period to period based on
the activities performed and the timing of expenses. The level of drilling activity impacts competition for personnel, supplies and equipment. Increased competition
could place upward pressure on the cost of labor, supplies and miscellaneous equipment.

Use
of
Non-GAAP
Financial
Measures

Gross margin, Adjusted EBITDA, Adjusted interest expense, DCF and Distribution coverage ratio are not financial measures presented in accordance with
GAAP. These financial measures are subject to adjustments that have the effect of excluding amounts that are included in the most directly comparable measure
calculated  and  presented  in  accordance  with  GAAP.  Because  these  non-GAAP  financial  measures  exclude  amounts  that  are  included  in  the  most  directly
comparable  GAAP  financial  measures,  they  have  important  limitations  as  an  analytical  tool.  We  nevertheless  believe  that  the  presentation  of  these  non-GAAP
financial measures provides useful information to investors regarding our financial condition and results of operations because they are the financial measures used
by management to evaluate and manage our business.

We have provided definitions  for Gross margin,  Adjusted EBITDA, Adjusted interest  expense, DCF and Distribution  coverage  ratio. Although the use of
non-GAAP financial measures with the same or similar titles is common in our industry, comparability may vary from one company to another. Because Gross
margin, Adjusted EBITDA, Adjusted interest expense, DCF and Distribution coverage ratio may be defined differently by other companies in our industry, our
presentation of these non-GAAP financial measures may not be directly comparable to non-GAAP financial measures of other companies with the same or similar
titles.

Gross margin is most directly comparable to the GAAP financial measure revenue. When used as a financial measure, Adjusted EBITDA is most directly
comparable  to  the  GAAP  financial  measure  net  income  attributable  to  limited  partners.  When  used  as  a  liquidity  measure,  Adjusted  EBITDA  is  most  directly
comparable to the GAAP liquidity measure net cash provided by operating activities. Adjusted interest expense is most directly comparable to the GAAP financial
measure interest expense. DCF is most directly comparable to the GAAP financial measure net income attributable to limited partners. Distribution coverage ratio
is  computed  utilizing  DCF,  which  is  most  directly  comparable  to  the  GAAP  financial  measure  net  income  attributable  to  limited  partners.  These  non-GAAP
financial  measures  should  not  be  considered  a  substitute  for  the  most  directly  comparable  financial  measures.  Reconciliations  of  these  non-GAAP  financial
measures to their most directly comparable GAAP financial measures are provided in “—Reconciliations of non-GAAP Financial Measures” below.

Gross Margin

We define gross margin as total revenues minus costs of natural gas and natural gas liquids, excluding depreciation and amortization. Total revenues consist
of the fees that we charge our customers and the sales price of natural gas and natural liquids that we sell. The cost of natural gas and natural gas liquids consists of
the purchase price of natural gas and natural gas liquids that we purchase. We deduct the cost of natural gas and natural gas liquids from total revenue to arrive at a
measure of the core profitability of our mix of fee-based and commodity-based customer arrangements. We use gross margin as a performance measure to analyze
the core profitability of our customer arrangements. Please read “—Results of Operations” and “—Use of Non-GAAP Financial Measures.”

66

Table of Contents

Adjusted EBITDA

We define Adjusted EBITDA as net income (loss) attributable to limited partners plus depreciation and amortization expense, interest expense, income tax
expense, distributions received from equity method affiliate in excess of equity earnings, non-cash equity-based compensation, impairments, changes in the fair
value  of  derivatives  and  certain  other  non-cash  losses  (including  losses  on  sales  of  assets  and  write-downs  of  materials  and  supplies),  less  the  noncontrolling
interests  share  of  Adjusted  EBITDA.  We  use  Adjusted  EBITDA  to  evaluate  our  operating  profitability  unburdened  by  our  capital  structure.  Because  Adjusted
EBITDA adds back to net income the non-cash accounting charges of depreciation and amortization  and disregards interest paid on debt financing and income
taxes on earnings, we believe that it is useful for measuring our operating cash flow. However, Adjusted EBITDA does not measure, and should not be confused
with, our actual cash flow which accounts for interest paid on debt financing, income taxes and other cash charges.

Adjusted Interest Expense

We define adjusted interest expense as interest expense plus amortization of premium on long-term debt and capitalized interest, less amortization of debt

costs and discount on long-term debt. We use adjusted interest expense to assess the Partnership’s ability to incur and service debt and fund capital expenditures.

DCF

We  define  DCF  as  Adjusted  EBITDA,  as  further  adjusted  for  Series  A  Preferred  Unit  distributions,  Adjusted  interest  expense,  maintenance  capital
expenditures, compensation expense for distribution equivalent rights of phantom and performance units and current income taxes. We use DCF as a proxy for
measuring  cash  available  for  distributions.  However,  DCF  does  not  reflect  the  cash  reserves  set  aside  for  our  operations  by  our  Board  of  Directors  prior  to
determining  the  amount  of  our  distributions  to  our  limited  partners,  and  should  not  be  confused  with  our  actual  cash  available  for  distribution.  For  more
information on the determination of our distributions by our Board of Directors see “Liquidity and Capital Resources—Distributions of Available Cash” below.

Distribution Coverage Ratio

We define Distribution coverage ratio as DCF divided by distributions related to common and subordinated unitholders. DCF is most directly comparable to
net  income  attributable  to  limited  partners,  which  is  reconciled  below.  We  use  Distribution  coverage  ratio  to  assess  the  ability  of  the  Partnership’s  assets  to
generate sufficient cash flow to make distributions to its partners.

Gathering
and
Processing

2018 compared to 2017 . Our gathering and processing segment reported operating income of $464 million for 2018 compared to $327 million for 2017 .
The difference of $137 million in operating income between periods was primarily due to a $192 million increase in gross margin. This was partially offset by a
$31  million  increase in  depreciation  and  amortization,  a  $23  million  increase in  operation  and  maintenance  and  general  and  administrative  expenses  and  a  $1
million increase in taxes other than income tax in 2018 .

Our gathering and processing segment revenues increase d $648 million in 2018 . The increase was primarily due to the following:

Product Sales:
•

revenues from NGL sales increased $459 million resulting from higher average NGL prices, higher processed volumes and increased recoveries
of ethane in the Anadarko and Ark-La-Tex Basins, inclusive of a $29 million decrease due to the implementation of ASC 606, and
changes in the fair value of natural gas, condensate and NGL derivatives increased $23 million.

Table of Contents

These increases were partially offset by:
•

revenues from natural gas sales decreased $4 million due to a $44 million decrease related to the implementation of ASC 606, partially offset by
a $40 million increase due to higher sales volumes offset by a lower average price.

Service Revenues:

•

•

•

processing service revenues increased $128 million resulting from higher processed volumes primarily under fixed processing arrangements in
the Anadarko and Ark-La-Tex Basins, inclusive of a $70 million increase due to the implementation of ASC 606,
natural gas gathering revenues increased $37 million due to higher fees and gathered volumes in the Anadarko and Ark-La-Tex Basins, inclusive
of a $46 million decrease due to the implementation of ASC 606, and
crude oil, condensate and produced water gathering revenues increased $9 million driven by a $5 million increase in the Anadarko Basin due to
the  acquisition  of  EOCS  and  a  $4  million  increase  in  the  Williston  Basin  due  to  higher  gathered  volumes,  partially  offset  by  a  reduction  in
average rates.

These increases were partially offset by a $4 million decrease in intercompany management fees.

Our gathering and processing segment gross margin increase d $192 million in 2018 . The increase was primarily due to the following:

•

•

•
•

•

processing service fees increased $128 million resulting from higher processed volumes primarily under fixed processing arrangements in the
Anadarko and Ark-La-Tex Basins, inclusive of a $70 million increase due to the implementation of ASC 606,
natural gas gathering fees increased $37 million due to higher fees and gathered volumes in the Anadarko and Ark-La-Tex Basins, inclusive of a
$46 million decrease due to the implementation of ASC 606,
changes in the fair value of natural gas, condensate and NGL derivatives increased $23 million,
revenues from NGL sales less the cost of NGLs increased $10 million inclusive of a $64 million decrease due to the implementation of ASC
606, partially offset by higher average NGL prices and higher processed volumes in the Anadarko and Ark-La-Tex Basins, and
crude oil, condensate and produced water gathering revenues increased $9 million driven by a $5 million increase in the Anadarko Basin due to
the  acquisition  of  EOCS  and  a  $4  million  increase  in  the  Williston  Basin  due  to  higher  gathered  volumes,  partially  offset  by  a  reduction  in
average rates.

These increases were partially offset by:
•

revenues from natural gas sales less the cost of natural gas decreased $11 million primarily due to a $36 million decrease due to lower average
prices  partially  offset  by  higher  sales  volumes  and  a  $15  million  increase  in  fuel  costs,  inclusive  of  a  $40  million  increase  due  to  the
implementation of ASC 606, and
a $4 million decrease in intercompany management fees.

•

Our gathering and processing segment operation and maintenance and general and administrative expenses increase d $23 million in 2018 . The increase was
primarily due to an $11 million increase related to maintenance on treating plants as a result of increased activity on our Ark-La-Tex assets, an $8 million increase
in compressor rental expenses due to increased rental units, an $8 million increase in materials and supplies and contract services as a result of additional assets in
service, a $5 million increase in payroll-related costs and a $4 million increase in acquisition costs. These were partially offset by a $7 million decrease due to a
loss on the disposal of assets in 2017, for which there were no comparable items in 2018, a $5 million decrease due to an increase in capitalized overhead costs as a
result of increased capital projects in 2018 and a $2 million change in the allowance for doubtful accounts due to the collection of accounts receivable in the year
ended December 31, 2018 that were previously included in the allowance for doubtful accounts.

Our gathering and processing segment depreciation and amortization expense increase d $31 million in 2018 due to additional assets placed in service.

Our gathering and processing segment taxes other than income tax increase d $1 million in 2018 due to higher accrued ad valorem taxes due to additional

assets placed in service.

2017 compared to 2016 . Our gathering and processing segment reported operating income of $327 million for 2017 compared to $196 million for 2016 .
The difference of $131 million in operating income between periods was primarily due to a $160 million increase in gross margin and no impairments recognized
in 2017 as compared to $9 million of impairments recognized in 2016 .

This  was  partially  offset  by  a  $20  million  increase  in  depreciation  and  amortization,  a  $13  million  increase  in  operation  and  maintenance  and  general  and
administrative expenses and a $5 million increase in taxes other than income tax in 2017 .

Our gathering and processing segment revenues increase d $530 million in 2017 . The increase was primarily due to a $315 million increase in revenues
from NGL sales resulting from higher average NGL prices and higher processed volumes in the Anadarko Basin, a $116 million increase in revenues from sales of
natural gas as a result of higher average natural gas prices and higher gathering volumes in the Anadarko and Ark-La-Tex Basins, a $39 million increase in natural
gas  gathering  revenues  due  to  higher  fees  and  gathering  volumes  in  the  Anadarko  and  Ark-La-Tex  Basins  and  increased  billings  under  minimum  volume
commitments  in  the  Arkoma  Basin,  a  $28  million  increase  in  processing  revenues  resulting  from  higher  processed  volumes  and  from  a  percent-of-proceeds
contract that was converted to a fee-based contract in the fourth quarter of 2016, a $27 million increase in revenues from changes in the fair value of condensate
and NGL derivatives, a $3 million increase due to increased water transportation revenues, a $2 million increase due to crude oil transportation revenues in the
Williston Basin and a $2 million increase due to an increase in intercompany management fees. These increases were partially offset by a $4 million decrease in
revenues due to a wind-down of third-party measurement and communication services in 2017.

Our gathering  and processing  segment  gross margin  increase d $160 million in 2017 . The increase  was primarily  due to a $62 million  increase  in gross

increase in processing margins resulting from higher average NGL prices and higher processed volumes in the Anadarko Basin, a $32 million increase in gathering
margin due to increased gathering volumes in the Anadarko and Ark-La-Tex Basins and increased billings under minimum volume commitments in the Arkoma
Basin,  a  $27  million  increase  in  gross  margin  from  changes  in  the  fair  value  of  condensate  and  NGL  derivatives,  a  $3  million  increase  due  to  increased  water
transportation  services,  a  $2  million  increase  due  to  crude  oil  transportation  services  in  the  Williston  Basin  and  a  $2  million  increase  due  to  an  increase  in
intercompany management fees. These increases were partially offset by a $6 million decrease in gross margin associated with our annual fuel rate determination
and a $4 million decrease in gross margin due to a wind-down of third-party measurement and communication services in 2017 .

Our gathering and processing segment operation and maintenance and general and administrative expenses increase d $13 million in 2017 . The increase was

Net Income attributable to limited partners. We reported net income attributable to limited partners of $521 million in 2018 compared to $436 million in
2017 .  The  increase in  net  income  attributable  to  limited  partners  was  primarily  due  to  an  increase in  operating  income  of  $120  million  partially  offset  by  an
increase in interest expense of $32 million .

Interest Expense. Interest expense increase d by $32 million in 2018 due to an increase in the amount of debt outstanding as well as higher interest rates on
the  Partnership’s  outstanding  debt  as  a  result  of  a  long-term  debt  issuance  in  May  2018  that  resulted  in  the  repayment  of  all  amounts  outstanding  under  the
Partnership’s 2015 Term Loan Agreement, as well as amounts outstanding under our commercial paper program.

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  Consolidated  Financial  Statements.  Gross  margin,  Adjusted  EBITDA,  Adjusted  interest  expense,  DCF  and
Distribution coverage ratio are part of the performance measures that we

73

 
 
 
 
 
 
 
   
   
 
 
   
   
Table of Contents

use to manage the Partnership. For definitions and a description of management’s use of Gross margin, Adjusted EBITDA, Adjusted interest expense, DCF and
Distribution coverage ratio, see “—Measures We Use to Evaluate Results of Operations” above.

Provided below are reconciliations of Gross margin to total revenues, Adjusted EBITDA and DCF to net income attributable to limited partners, 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  financial  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.

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, 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 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. As of December 31, 2018
, we had a working capital deficit of $1,166 million . The deficit is primarily due to the $500 million 2019 Notes in short-term debt as well as $649 million

of commercial paper outstanding as of  December 31, 2018 . We utilize our commercial paper program and revolving credit facility to manage the timing of cash
flows and fund short-term working capital deficits.

The increase of $90 million , or 11% , in net cash provided by operating activities for the year ended December 31, 2018 as compared to the year ended
December 31, 2017 is primarily due to an increase in net income of $86 million as a result of an increase in gathering and processing revenues, partially offset by
an increase in cost of natural gas and natural gas liquids.

The increase of $113 million , or 16% , in net cash provided by operating activities for the year ended December 31, 2017 as compared to the year ended

December 31, 2016 is primarily due to an increase in net income of $124 million as a result of an increase in gathering and processing revenues, partially offset by
an increase in cost of natural gas and natural gas liquids.

The increase of $448  million  ,  or  63% ,  in  net  cash  used  in  investing  activities  for  the  year  ended  December  31,  2018  as  compared  to  the  year ended
December 31, 2017 was primarily due to higher capital expenditures of $457 million, including the $443 million acquisition of EOCS, net of cash received, in the
fourth quarter of 2018. This increase is partially offset by an increase in proceeds from the sale of assets of $7 million and an increase in the return of investment in
equity method affiliates of $2 million.

The increase of $339  million  ,  or  92% ,  in  net  cash  used  in  investing  activities  for  the  year  ended  December  31,  2017  as  compared  to  the  year ended
December 31, 2016 was primarily due to higher capital expenditures of $331 million, including the $298 million acquisition of Align Midstream, LLC in 2017, as
well as a decrease in return of investment of equity method affiliate of $10 million. These increases are partially offset by $2 million of proceeds received in 2017
from an insurance settlement.

As of December 31, 2018 , our sources of liquidity included:

•

•

•

•

cash on hand;

cash generated from operations;

proceeds from commercial paper issuances and borrowings under our Revolving Credit facility; and

capital raised through debt and equity markets.

Please see Note 6. “Enable Midstream Partners, LP Partners’ Equity” and Note 11. “Debt” in the Notes to the Consolidated Financial Statements under Item
8.  “Financial  Statements  and  Supplementary  Data”  for  cash  distributions  to  common  and  subordinated  unitholders  and  a  description  of  the  Partnership’s  debt
agreements.

ATM Program

On  May  12,  2017,  the  Partnership  entered  into  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. For the year ended  December 31, 2018 , the Partnership
issued 140,920 common units under the ATM Program, which generated proceeds of approximately $2 million (net of approximately $25,000 of commissions).
For  the  year  ended  December  31,  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 commissions). The Partnership incurred approximately $345,000 of expenses associated with the filing of
the registration statements for the ATM Program. The proceeds were used for general partnership purposes. As of December 31, 2018 , $197 million of common
units remained available for issuance through the ATM Program.

Distribution Reinvestment Plan

In June 2016, the Partnership implemented a Distribution Reinvestment Plan (DRIP), which, beginning with the quarterly distribution for the quarter ended
September 30, 2016, offers owners of our common units the ability to purchase additional common units by reinvesting all or a portion of the cash distributions
paid to them on their common units. The Partnership will have the sole discretion to determine whether common units purchased under the DRIP will come from
our newly issued common units or from common units purchased on 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

78

 
 
 
 
 
 
   
   
 
Table of Contents

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.
The Partnership has had minimal participation in the DRIP since its inception in June 2016 and, on July 31, 2018, the Partnership suspended the DRIP.

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.

For  the  year  ending  December  31,  2019,  we  estimate  that  expansion  capital  could  range  from  approximately  $325  million  to  $425  million  and  our
maintenance capital could range from approximately $105 million to $125 million. 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, issuances of commercial paper, 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
of
Available
Cash

General

Our Partnership Agreement requires that, within 60 days after the end of each quarter, we distribute all of our Available Cash (defined below) to unitholders

of record on the applicable record date.

Definition of Available Cash

Available cash is defined in our Partnership Agreement, which is an exhibit to this Annual Report on Form 10-K. Available cash generally means, for any

quarter, all cash and cash equivalents on hand at the end of that quarter:

•

less , the amount of cash reserves established by our general partner to:

•

•

•

provide for the proper conduct of our business (including cash reserves for our future capital expenditures, future acquisitions and anticipated
future debt service requirements and refunds of collected rates reasonably likely to be refunded as a result of a settlement or hearing related to
FERC rate proceedings or rate proceedings under applicable law subsequent to that quarter);

comply with applicable law, any of our debt instruments or other agreements;

provide  funds  for  distributions  to  our  unitholders  and  to  our  general  partner  for  any  one  or  more  of  the  next  four  quarters  (provided  that  our
general  partner  may  not  establish  cash  reserves  for  distributions  if  the  effect  of  the  establishment  of  such  reserves  will  prevent  us  from
distributing  the  minimum  quarterly  distribution  on  all  common  units  and  any  cumulative  arrearages  on  such  common  units  for  the  current
quarter); or

•

provide funds for distributions on our preferred units;

•

plus , if our general partner so determines, all or any portion of the cash on hand on the date of determination of available cash for the quarter resulting
from working capital borrowings made subsequent to the end of such quarter.

Minimum Quarterly Distribution

The Minimum Quarterly Distribution, as set forth in the Partnership Agreement, is $0.2875 per unit per quarter, or $1.15 per unit on an annualized basis to
the extent we have sufficient cash from our operations after the establishment of cash reserves and the payment of costs and expenses, including reimbursements of
expenses to our general partner. Our current quarterly distribution is $0.318 per unit, or $ 1.272 per unit annualized. However, there is no guarantee that we will
pay the minimum quarterly distribution on our units in any quarter. Even if our cash distribution policy is not modified or revoked, the amount of distributions paid
under

79

 
Table of Contents

our policy and the decision to make any distribution is determined by our general partner, taking into consideration the terms of our Partnership Agreement. Please
read “—Liquidity and Capital Resources” for a discussion of the restrictions included in our credit agreement that may restrict our ability to make distributions.

Percentage Allocations of Available Cash from Operating Surplus

The following table illustrates the percentage allocations of available cash from operating surplus between the unitholders and our general partner (through
the incentive distribution rights) based on the specified target distribution levels. The amounts set forth under “Marginal Percentage Interest in Distributions” are
the percentage interests of our general partner and the unitholders in any available cash from operating surplus we distribute up to and including the corresponding
amount  in  the  column  “Total  Quarterly  Distribution  Per  Unit  Target  Amount.”  The  percentage  interests  shown  for  our  unitholders  for  the  minimum  quarterly
distribution are also applicable to quarterly distribution amounts that are less than the minimum quarterly distribution. The percentage interests set forth below for
our general partner assume that our general partner has not transferred its incentive distribution rights and that there are no arrearages on common units.

In determining the amount of available cash for distributions to holders of common units, the Board of Directors determines the amount of cash reserves to
set aside for our operations, including reserves for future working capital, maintenance capital expenditures, expansion capital expenditures, acquisitions and other
matters, which will impact the amount of cash we are able to distribute to our unitholders. However, we expect that we will rely primarily upon external financing
sources,  including  borrowings  under  our  Revolving  Credit  Facility  and  issuances  of  debt  and  equity  securities,  as  well  as  cash  reserves,  to  fund  our  expansion
capital expenditures including acquisitions. To the extent we are unable to finance growth externally and are unwilling to establish cash reserves to fund future
expansions, our available cash for distributions will not significantly  increase. In addition, because we distribute all of our available cash, we may not grow as
quickly as businesses that reinvest their available cash to expand ongoing operations. To the extent we issue additional units in connection with any expansion
capital expenditures including acquisitions, or to the extent we issue additional units ranking senior to our common units, the payment of distributions on those
additional  units  may  increase  the  risk  that  we  will  be  unable  to  maintain  or  increase  our  per  unit  distribution  level.  There  are  no  limitations  in  our  Partnership
Agreement or in the terms of our Revolving Credit Facility on our ability to issue additional units, including units ranking senior to the common units.

(1) The board of directors of Enable GP declared this $0.318 per common unit cash distribution on February 8, 2019 , to be paid on February 26, 2019 , to unitholders of

record at the close of business on February 19, 2019 .

On  February  18,  2016,  we  completed  the  private  placement  of  14,520,000  Series  A  Preferred  Units.  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%. The Series A Preferred Units rank senior to the
Partnership’s common units with respect to the payment of distributions and, unless full distributions are paid on the Series A Preferred Units with respect to a
quarter, we cannot declare or pay a distribution on common units with respect to that quarter. We intend to pay full distributions on Series A Preferred Units each
quarter, however these distributions are not mandatory, and we do not have a legal obligation to pay these distributions. For more information on our Series A
Preferred Units, see Note 6. “Enable Midstream Partners, LP Partners’ Equity” included in Item 8. “Financial Statements and Supplementary Data—Notes to the
Consolidated Financial Statements.”

Critical Accounting Policies and Estimates

Our  financial  statements  and  the  related  notes  thereto  contain  information  that  is  pertinent  to  Management’s  Discussion  and  Analysis.  In  preparing  our
financial  statements,  management  is  required  to  make  estimates  and  assumptions  that  affect  the  reported  amounts  of  assets  and  liabilities  and  disclosure  of
contingent assets and contingent liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period.
Changes to these assumptions and estimates could have a material effect on the Partnership’s financial statements. However, the Partnership believes it has taken
reasonable, but conservative, positions where assumptions and estimates are used in order to minimize the negative financial impact to the Partnership that could
result  if  actual  results  vary  from  the  assumptions  and  estimates.  In  management’s  opinion,  the  areas  of  the  Partnership  where  the  most  significant  judgment  is
exercised for all Partnership segments includes the determination of impairment estimates of long-lived assets (including intangible assets) and goodwill, revenue
recognition, valuation of assets and depreciable lives of property, plant and equipment and amortization methodologies related to intangible assets. The selection,
application and disclosure of the following critical accounting estimates have been discussed with the Partnership’s board of directors. The Partnership discusses its
significant accounting policies, including those that do not require management to make difficult, subjective, or complex judgments or estimates, in Note 1 of the
Notes to the Consolidated Financial Statements.

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 the
year  ended  December  31,  2016,  the  Partnership  recorded  an  impairment  of  $9  million  on  the  Service  Star  business  line,  a  component  of  our  gathering  and
processing segment. The Partnership recorded no other material impairments to long-lived assets in the years ended December 31, 2018 , 2017 or 2016 . Based
upon  review  of  forecasted  undiscounted  cash  flows  as  of  December  31,  2018  ,  all  of  the  asset  groups  were  considered  recoverable.  Future  price  declines,
throughput declines, contracted capacity declines, cost increases, regulatory or political environment changes and other changes in market conditions could reduce
forecasted undiscounted cash flows.

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. If
the estimated fair value of the reporting unit is less than the carrying amount of the reporting unit, then a second step must be completed in order to determine the
amount of the goodwill impairment that should be recorded. In the second step, the implied fair value of the reporting unit’s goodwill is determined by allocating
the reporting unit’s fair value to all of its assets and liabilities other than goodwill (including any unrecognized intangible assets) in a manner similar to a purchase
price allocation. The resulting implied fair value of the goodwill that results from the application of this second step is then compared to the carrying amount of the
goodwill and an impairment charge is recorded for the difference. The Partnership performs its goodwill impairment testing one level below the transportation and
storage and gathering and processing reportable segment level.

Because  quoted  market  prices  for  the  Partnership’s  reporting  units  are  not  available,  management  must  apply  judgment  in  determining  the  estimated  fair
value of reporting units for purposes of performing the goodwill impairment test, when necessary. Management considered observable transactions in the market,
as well as trading multiples and cost of capital for peers, to determine appropriate multiples and discount rates to apply against historical and forecasted cash flows.
A lower fair value estimate in the future for any of the Partnership’s reporting units could result in a goodwill impairment. Factors that could trigger a lower fair
value estimate include sustained price declines, throughput declines, contracted capacity declines, cost increases, regulatory or political environment changes and
other changes in market conditions such as decreased prices in market-based transactions for similar assets.

As  of  December  31,  2016,  the  Partnership  had  no  goodwill  recognized  on  its  Consolidated  Balance  Sheet.  During  the  fourth  quarter  of  the  year  ended
December 31, 2017, the Partnership recognized $12 million of goodwill related to the acquisition of Align. During the fourth quarter of 2018, as a result of the
acquisition of EOCS, the Partnership recorded $86 million of goodwill. All goodwill is included in the gathering and processing reportable segment.

Revenue
Recognition

The  Partnership  generates  the  majority  of  its  revenues  from  midstream  energy  services,  including  natural  gas  gathering,  processing,  transportation  and
storage and crude oil, condensate and produced water gathering. The Partnership performs these services under various contractual arrangements, which include
fee-based contract arrangements and arrangements pursuant to which it purchases and resells commodities in connection with providing the related service and
earns a net margin for its fee. The Partnership reflects revenue as Product sales and Service revenue on the Consolidated Statements of Income as follows:

Product sales: Product sales represent the sale of natural gas, NGLs, crude oil and condensate where the product is purchased and used in connection with

providing the Partnership’s midstream services.

Service revenue: Service revenue represents all other revenue generated as a result of performing the Partnership’s midstream services.

The Partnership recognizes revenue from natural gas gathering, processing, transportation and storage and crude oil, condensate and water gathering services
to  third  parties  in  accordance  with  ASU  No.  2014-09  “Revenue  from  Contracts  with  Customers”  (Topic  606)  upon  its  adoption  on  January  1,  2018.  As  the
Partnership  adopted  using  the  modified  retrospective  method,  revenue  for  all  periods  prior  to  January  1,  2018  were  recognized  in  accordance  with  “Revenue
Recognition”  (Topic  605).  Please  see  Note  3.  “Revenues”  in  the  Notes  to  the  Consolidated  Financial  Statements  under  Item  8.  “Financial  Statements  and
Supplementary Data” for a description of the impact of adoption. Under Topic 606, revenue is recognized at an amount that reflects the consideration to which the
entity expects to be entitled in exchange for transferring goods or services. The determination of that amount and the timing of recognition is based on identifying
the  contracts  with  customers,  identifying  the  performance  obligations  in  the  contract,  determining  the  transaction  price,  allocating  the  transaction  price  to  the
performance obligations in the contract, and ultimately recognizing revenue when (or as) the entity satisfies the performance obligation.

Service revenues for gathering, processing, transportation and storage services for the Partnership are recorded each month as services have been completed
and performance obligations are met. Product revenues are recognized when control is transferred. Monthly revenues are based on the current month’s estimated
volumes, contracted prices (considering current commodity prices), historical seasonal fluctuations and any known adjustments. The estimates are reversed in the
following month and customers are billed on actual volumes and contracted prices. Gas sales are calculated on current-month nominations and contracted prices.
Revenues associated with the production of NGLs are estimated based on current-month estimated production and contracted prices. These amounts are reversed in
the  following  month  and  the  customers  are  billed  on  actual  production  and  contracted  prices.  Estimated  revenues  are  reflected  in  Accounts  receivable,  net  or
Accounts receivable—affiliated companies, as appropriate, on the Consolidated Balance Sheets and in Total revenues on the Consolidated Statements of Income.

The Partnership records deferred revenue when it receives consideration from a third party before achieving certain criteria that must be met for revenue to be
recognized in accordance with GAAP. The Partnership had $48 million and $34 million of deferred revenues, including deferred revenue—affiliated companies,
included in Other current liabilities and Other long-term liabilities on the Consolidated Balance Sheets at each of December 31, 2018 and 2017 , respectively.

Please see Note 3. “Revenues” in the Notes to the Consolidated Financial Statements under Item 8. “Financial Statements and Supplementary Data” for a

description of ASU No. 2014-09, “Revenue from Contracts with Customers (Topic 606).

Valuation
of
Assets

The application of business combination and impairment accounting requires the Partnership to use significant estimates and assumptions in determining the
fair  value  of  assets  and  liabilities.  The  acquisition  method  of  accounting  for  business  combinations  requires  the  Partnership  to  estimate  the  fair  value  of  assets
acquired  and  liabilities  assumed  to  allocate  the  proper  amount  of  the  purchase  price  consideration  between  goodwill  and  the  assets  that  are  depreciated  and
amortized. The Partnership records intangible assets separately from goodwill and amortizes intangible assets with finite lives over their estimated useful life as
determined by management. The Partnership does not amortize goodwill but instead annually assesses goodwill for impairment.

In the years ended December 31, 2018 and 2017, the Partnership completed acquisitions accounted for as business combinations as discussed in Note 4 of the
Notes to the Consolidated Financial Statements. As part of these acquisitions, the Partnership engaged the services of third-party valuation specialists to assist it in
determining the fair value of the acquired assets and liabilities, including goodwill; however, the ultimate determination of those values is the responsibility of the
Partnership’s  management.  The  Partnership  bases  its  estimates  on  assumptions  believed  to  be  reasonable,  but  which  are  inherently  uncertain.  These  valuations
require the use of management’s assumptions, which would not reflect unanticipated events and circumstances that may occur.

Assets

The computation of depreciation expense requires judgment regarding the estimated useful lives and salvage value of assets at the time the assets are placed
in service. As circumstances warrant, useful lives are adjusted when changes in planned use, changes in estimated production lives of affiliated natural gas basins
or other factors indicate that a different life would be more appropriate. Such changes could materially impact future depreciation expense. Changes in useful lives
that  do  not  result  in  the  impairment  of  an  asset  are  recognized  prospectively.  The  computation  of  amortization  expense  on  intangible  assets  requires  judgment
regarding the amortization method used. Intangible assets are amortized on a straight-line basis over their useful lives using a method of amortization that reflects
the pattern in which the economic benefits of the intangible asset are consumed.

Item 7A. 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 12 of the Notes to Consolidated Financial Statements in Part II, Item 8. “Financial Statements and Supplementary Data.”

Based  on  our  forecasted  volumes,  prices  and  contractual  arrangements,  we  estimate  approximately  12%  of  our  total  gross  margin  for  the  twelve  months
ending December 31, 2019 will be directly exposed to changes in commodity prices, excluding the impact of hedges and contractual floors related to commodity
prices in certain agreements. Since December 31, 2018 , we have entered into additional derivative contracts to further manage our exposure to commodity price
risk for the twelve 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 12 months. Based on a
sensitivity analysis, a 10% decrease in prices from forecasted levels would decrease net income by approximately $15 million for natural gas and ethane and $9
million for NGLs (other than ethane) and condensate, excluding the impact of hedges for the twelve months ending December 31, 2019 .

Interest
Rate
Risk

Our current interest rate risk exposure is related primarily to our debt portfolio. The majority of our debt portfolio is comprised of fixed rate debt, 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 and any issuances under our commercial paper program could be at a variable interest rate
and  could  expose  us  to  the  risk  of  increasing  interest  rates.  Based  upon  the  $899  million  outstanding  borrowings  under  the  Revolving  Credit  Facility  and
commercial paper program as of December 31, 2018 , and holding all other variables constant, a 100 basis-point, or 1%, increase in interest rates would increase
our annual interest expense by approximately $9 million.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors of Enable GP, LLC and
Unitholders of Enable Midstream Partners, LP
Oklahoma City, Oklahoma

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Enable Midstream Partners, LP and subsidiaries (the "Partnership") as of December 31, 2018
and 2017, the related consolidated statements of income, cash flows, and partners’ equity for each of the three years in the period ended December 31, 2018, and
the related notes (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the financial
position of the Partnership as of December 31, 2018 and 2017, and the results of its operations and its cash flows for each of the three years in the period ended
December 31, 2018 in conformity with accounting principles generally accepted in the United States of America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Partnership's internal
control over financial reporting as of December 31, 2018, based on criteria established in Internal Control—Integrated Framework (2013) issued by the Committee
of Sponsoring Organizations of the Treadway Commission and our report dated February 19, 2019, expressed an unqualified opinion on the Partnership's internal
control over financial reporting.

Basis for Opinion

These  financial  statements  are  the  responsibility  of  the  Partnership's  management.  Our  responsibility  is  to  express  an  opinion  on  the  Partnership's  financial
statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Partnership in
accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We  conducted  our  audits  in  accordance  with  the  standards  of  the  PCAOB.  Those  standards  require  that  we  plan  and  perform  the  audit  to  obtain  reasonable
assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to
assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such
procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the
accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe
that our audits provide a reasonable basis for our opinion.

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

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

At  December  31,  2018  ,  CenterPoint  Energy  held  approximately  54.0%  or  233,856,623  of  the  Partnership’s  common  units,  and  OGE  Energy  held
approximately 25.6% or 110,982,805 of the Partnership’s common units. Additionally, CenterPoint Energy holds 14,520,000 Series A Preferred Units. See Note 6
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) on an annual or continuing basis and may not remove

For the years ended December 31, 2018 , 2017 and 2016 , the Partnership owned a 50% interest in SESH. See Note 10 for further discussion of SESH. For
the years ended December 31, 2018 , 2017 and 2016 , the Partnership held a 50% ownership interest in Atoka and consolidated Atoka in its Consolidated Financial
Statements as EOIT acted as the managing member of Atoka and had control over the operations of Atoka. In addition, for the period November 1, 2018 through
December 31, 2018 , the Partnership owned a 60% interest in VPP, which is consolidated in its Consolidated Financial Statements as EOCS acted as the managing
member of VPP and had control over the operations of VPP.

Basis
of
Presentation

The accompanying consolidated financial statements and related notes of the Partnership have been prepared pursuant to the rules and regulations of the SEC

and GAAP.

 For a description of the Partnership’s reportable segments, see Note 19.

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.

Revenue
Recognition

The  Partnership  generates  the  majority  of  its  revenues  from  midstream  energy  services,  including  natural  gas  gathering,  processing,  transportation  and
storage and crude oil, condensate and produced water gathering. The Partnership performs these services under various contractual arrangements, which include
fee-based contract arrangements and arrangements pursuant to which it purchases and resells commodities in connection with providing the related service and
earns a net margin for its fee. The Partnership reflects revenue as Product sales and Service revenue on the Consolidated Statements of Income as follows:

Product sales: Product sales represent the sale of natural gas, NGLs, crude oil and condensate where the product is purchased and used in connection with

providing the Partnership’s midstream services.

Service revenue: Service revenue represents all other revenue generated as a result of performing the Partnership’s midstream services.

The Partnership recognizes revenue from natural gas gathering, processing, transportation and storage and crude oil, condensate and water gathering services
to  third  parties  in  accordance  with  ASU  No.  2014-09  “Revenue  from  Contracts  with  Customers”  (Topic  606)  upon  its  adoption  on  January  1,  2018.  As  the
Partnership  adopted  using  the  modified  retrospective  method,  revenue  for  all  periods  prior  to  January  1,  2018  were  recognized  in  accordance  with  “Revenue
Recognition”  (Topic  605).  Please  see  Note  3.  “Revenues”  in  the  Notes  to  the  Consolidated  Financial  Statements  under  Item  8.  “Financial  Statements  and
Supplementary Data” for a description of the impact of adoption. Under Topic 606, revenue is recognized at an amount that reflects the consideration to which the
entity expects to be entitled in exchange for transferring goods or services. The determination of that amount and the timing of recognition is based on identifying
the  contracts  with  customers,  identifying  the  performance  obligations  in  the  contract,  determining  the  transaction  price,  allocating  the  transaction  price  to  the
performance obligations in the contract, and ultimately recognizing revenue when (or as) the entity satisfies the performance obligation.

Service revenues for gathering, processing, transportation and storage services for the Partnership are recorded each month as services have been completed
and performance obligations are met. Product revenues are recognized when control is transferred. Monthly revenues are based on the current month’s estimated
volumes, contracted prices (considering current commodity prices), historical seasonal fluctuations and any known adjustments. The estimates are reversed in the
following month and customers are billed on actual volumes and contracted prices. Gas sales are calculated on current-month nominations and contracted prices.
Revenues associated with the production of NGLs are estimated based on current-month estimated production and contracted prices. These amounts are reversed in
the  following  month  and  the  customers  are  billed  on  actual  production  and  contracted  prices.  Estimated  revenues  are  reflected  in  Accounts  receivable,  net  or
Accounts receivable—affiliated companies, as appropriate, on the Consolidated Balance Sheets and in Total revenues on the Consolidated Statements of Income.

The Partnership records deferred revenue when it receives consideration from a third party before achieving certain criteria that must be met for revenue to be
recognized in accordance with GAAP. The Partnership had $48 million and $34 million of deferred revenues, including deferred revenue—affiliated companies,
included in Other current liabilities and Other long-term liabilities on the Consolidated Balance Sheets at December 31, 2018 and 2017 , respectively.

The  Partnership  relies  on  certain  key  natural  gas  producer  customers  for  a  significant  portion  of  natural  gas  and  NGLs  supply.  The  Partnership  relies  on
certain  key utilities  for  a significant  portion  of transportation  and storage  demand.  The Partnership  depends on third-party  facilities  to transport  and fractionate
NGLs that it delivers to third parties at the inlet of their facilities. Additionally, for the years ended December 31, 2018 , 2017 and 2016 , one third party purchased
approximately 12% , 13% and 22% , respectively, of the NGLs delivered off our system, which accounted for approximately $214 million , $140 million and $129
million , or 6% , 5% and 6% , respectively, of total revenues. Additionally, in the year ended December 31, 2018 and 2017 , another third party purchased 8% and
12% , respectively, of the NGLs delivered off our system, which accounted for $152 million and $127 million , respectively, or 4% and 4% , respectively, of total
revenues.  Other  than  revenues  from  affiliates  discussed  in  Note  15,  there  are  no  other  revenue  concentrations  with  individual  customers  in  the  years  ended
December 31, 2018 , 2017 and 2016 .

Natural
Gas
and
Natural
Gas
Liquids
Purchases

Cost  of  natural  gas  and  natural  gas  liquids  represents  cost  of  our  natural  gas  and  natural  gas  liquids  purchased  exclusive  of  depreciation,  Operation  and
maintenance and General and administrative expenses and consists primarily of product and fuel costs. Estimates for gas purchases are based on estimated volumes
and  contracted  purchase  prices.  Estimated  gas  purchases  are  included  in  Accounts  Payable  or  Accounts  Payable-affiliated  companies,  as  appropriate,  on  the
Consolidated  Balance  Sheets  and  in  Cost  of  natural  gas  and  natural  gas  liquids,  excluding  Depreciation  and  amortization  on  the  Consolidated  Statements  of
Income.

92

Table of Contents

Operation
and
Maintenance
and
General
and
Administrative
Expense

Operation  and maintenance  expense  represents  the cost  of our service  related  revenues  and consists  primarily  of labor  expenses,  lease  costs, utility  costs,
insurance  premiums  and  repairs  and  maintenance  expenses  directly  related  with  the  operations  of  assets.  General  and  administrative  expense  represents  cost
incurred to manage the business. This expense includes cost of general corporate services, such as treasury, accounting, legal, information technology and human
resources  and  all  other  expenses  necessary  or  appropriate  to  the  conduct  of  business.  Any  Operation  and  maintenance  expense  and  General  and  administrative
expense associated with product sales is immaterial.

Environmental
Costs

The Partnership expenses or capitalizes environmental expenditures, as appropriate, depending on their future economic benefit. The Partnership expenses
amounts that relate to an existing condition caused by past operations that do not have future economic benefit. The Partnership records undiscounted liabilities
related to these future costs when environmental assessments and/or remediation activities are probable and the costs can be reasonably estimated. There are no
material amounts accrued at December 31, 2018 or 2017 .

Depreciation
and
Amortization
Expense

Depreciation is computed using the straight-line method based on economic lives or a regulatory-mandated recovery period. Amortization of intangible assets

is computed using the straight-line method over the respective lives of the intangible assets.

The computation of depreciation expense requires judgment regarding the estimated useful lives and salvage value of assets at the time the assets are placed
in service. As circumstances warrant, useful lives are adjusted when changes in planned use, changes in estimated production lives of affiliated natural gas basins
or other factors indicate that a different life would be more appropriate. Such changes could materially impact future depreciation expense. Changes in useful lives
that  do  not  result  in  the  impairment  of  an  asset  are  recognized  prospectively.  The  computation  of  amortization  expense  on  intangible  assets  requires  judgment
regarding the amortization method used. Intangible assets are amortized on a straight-line basis over their useful lives using a method of amortization that reflects
the pattern in which the economic benefits of the intangible asset are consumed.

Income
Taxes

The Partnership’s earnings are not subject to income tax ( other than Texas state margin taxes and taxes associated with the Partnership’s corporate subsidiary

Enable Midstream Services) and are taxable at the individual partner level. For more information, see Note 17.

We account for deferred income taxes related to the federal and state jurisdictions using the asset and liability method. Under this method, deferred tax assets
and  liabilities  are  recognized  for  the  future  taxes  attributable  to  the  difference  between  financial  statement  carrying  amounts  of  assets  and  liabilities  and  their
respective  tax  basis.  Deferred  tax  assets  are  also  recognized  for  the  future  tax  benefits  attributable  to  the  expected  utilization  of  tax  net  operating  loss
carryforwards. In the event future utilization is determined to be unlikely, a valuation allowance is provided to reduce the tax benefits from such assets. Deferred
tax  assets  and  liabilities  are  measured  using  enacted  tax  rates  in  effect  for  the  period  in  which  the  temporary  differences  and  carryforwards  are  expected  to  be
recovered  or settled.  The effect  of a change in tax rates  is recognized  in the period which includes the enactment date. The Partnership  recognizes  interest  and
penalties as a component of income tax expense.

Cash
and
Cash
Equivalents

The Partnership considers cash equivalents to be short-term, highly liquid investments with maturities of three months or less from the date of purchase. The

Consolidated Balance Sheets have $8 million and $5 million of cash and cash equivalents as of December 31, 2018 and 2017 , respectively.

Restricted
Cash

Restricted cash consists of cash which is restricted by agreements with third parties. The Consolidated Balance Sheets have $14 million and $14 million of

restricted cash as of December 31, 2018 and 2017 , respectively.

Table of Contents

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,  we  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, the aging of receivables and specific customer circumstances that may impact their ability to pay the amounts due. Based on this
review, management determined that a $2 million and $3 million allowance for doubtful accounts was required at December 31, 2018 and 2017 , respectively.

Inventory

Materials and supplies inventory is valued at cost and is subsequently recorded at the lower of cost or net realizable value. The Partnership recorded no write-
downs to net realizable value related to materials and supplies inventory disposed or identified as excess or obsolete for the year ended December 31, 2018 and $1
million  for  each  of  the  years  ended  December  31,  2017  and  2016  .  Materials  and  supplies  are  recorded  to  inventory  when  purchased  and,  as  appropriate,
subsequently  charged  to  operation  and  maintenance  expense  on  the  Consolidated  Statements  of  Income  or  capitalized  to  property,  plant  and  equipment  on  the
Consolidated Balance Sheets when installed.

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. During the years ended December 31, 2018 , 2017 and 2016 , the Partnership recorded write-
downs  to  net  realizable  value  related  to  natural  gas  and  natural  gas  liquids  inventory  of  $4  million  , $2  million  and $3  million  ,  respectively.  The  cost  of  gas
associated  with  sales  of  natural  gas  and  natural  gas  liquids  inventory  is  presented  in  Cost  of  natural  gas  and  natural  gas  liquids,  excluding  depreciation  and
amortization on the Consolidated Statements of Income.

Gas  imbalances  occur  when  the  actual  amounts  of  natural  gas  delivered  from  or  received  by  the  Partnership’s  pipeline  systems  differ  from  the  amounts
scheduled to be delivered or received. Imbalances are due to or due from shippers and operators and can be settled in cash or natural gas depending on contractual
terms. The Partnership values all imbalances at individual, or where appropriate an average of, current market indices applicable to the Partnership’s operations,
not to exceed net realizable value.

Long-Lived
Assets
(including
Intangible
Assets)

The  Partnership  records  property,  plant  and  equipment  and  intangible  assets  at  historical  cost.  Newly  constructed  plant  is  added  to  plant  balances  at  cost
which includes contracted services, direct labor, materials, overhead, transportation costs and capitalized interest. Replacements of units of property are capitalized
as plant. For assets that belong to a common plant account, the replaced plant is removed from plant balances and charged to Accumulated depreciation. For assets
that do not belong to a common plant account, the replaced  plant is removed  from plant balances  with the related  accumulated  depreciation  and the remaining
balance  net  of  any  salvage  proceeds  is  recorded  as  a  loss  in  the  Consolidated  Statements  of  Income  as  Operation  and  maintenance  expense.  The  Partnership
expenses repair and maintenance costs as incurred. Repair, removal and maintenance costs are included in the Consolidated Statements of Income as Operation and
maintenance expense.

Assessing
Impairment
of
Long-lived
Assets
(including
Intangible
Assets)
and
Goodwill

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 13.

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. If
the estimated fair value of the reporting unit is less than the carrying amount of the reporting unit, then a second step must be completed in order to determine the
amount of the goodwill impairment that should be recorded. In the second step, the implied fair value of the reporting unit’s goodwill is determined by allocating
the reporting unit’s fair value to all of its assets and liabilities other than goodwill (including any unrecognized intangible assets) in a manner similar to a purchase
price allocation. The resulting implied fair value of the goodwill that results from the application of this second step is then compared to the carrying amount of the
goodwill and an impairment charge is recorded for the difference. The Partnership performs its goodwill impairment testing one level below the transportation and
storage and gathering and processing reportable segment level. For more information, see Note 9.

Regulatory
Assets
and
Liabilities

The Partnership applies the guidance for accounting for regulated operations to portions of the transportation and storage segment. The Partnership’s rate-
regulated businesses recognize removal costs as a component of depreciation expense in accordance with regulatory treatment. As of each of December 31, 2018
and 2017 , these removal costs of $23 million and $21 million , respectively, are classified as Regulatory liabilities in the Consolidated Balance Sheets.

Capitalization
of
Interest
and
Allowance
for
Funds
Used
During
Construction

Allowance for funds used during construction (AFUDC) represents the approximate net composite interest cost of borrowed funds and a reasonable return on
the equity funds used for construction. Although AFUDC increases both utility plant and earnings, it is realized in cash when the assets are included in rates for
entities that apply guidance for accounting for regulated operations. Capitalized interest represents the approximate net composite interest cost of borrowed funds
used for construction. Interest and AFUDC are capitalized as a component of projects under construction and will be amortized over the assets’ estimated useful
lives.  For  the  years  ended  December  31,  2018  , 2017 and 2016 ,  the  Partnership  capitalized  interest  and  AFUDC  of  $6  million  , $1  million  and $4  million  ,
respectively.

Derivative
Instruments

The Partnership is exposed to various market risks. These risks arise from transactions entered into in the normal course of business. At times, the Partnership
utilizes  derivative  instruments  such  as  physical  forward  contracts,  financial  futures  and  swaps  to  mitigate  the  impact  of  changes  in  commodity  prices  on  its
operating results and cash flows. Such derivatives are recognized in the Partnership’s Consolidated Balance Sheets at their fair value unless the Partnership elects
hedge accounting or the normal purchase and sales exemption for qualified physical transactions. For derivative instruments not designated as hedging instruments,
the gain or loss on the derivative is recognized in Product sales in the Consolidated Statements of Income. A derivative may be designated as a normal purchase or
normal sale if the intent is to physically receive or deliver the product for use or sale in the normal course of business.

The Partnership’s policies prohibit the use of leveraged financial instruments. A leveraged financial instrument, for this purpose, is a transaction involving a

derivative whose financial impact will be based on an amount other than the notional amount or volume of the instrument.

Fair
Value
Measurements

The  Partnership  determines  fair  value  as  the  price  that  would  be  received  to  sell  an  asset  or  paid  to  transfer  a  liability  in  an  orderly  transaction  between

market participants at the measurement date. As required, the Partnership utilizes valuation techniques

95

Table of Contents

that maximize the use of observable inputs (levels 1 and 2) and minimize the use of unobservable inputs (level 3) within the fair value hierarchy included in current
accounting guidance. The Partnership generally applies the market approach to determine fair value. This method uses pricing and other information generated by
market transactions for identical or comparable assets and liabilities. Assets and liabilities are classified within the fair value hierarchy based on the lowest level
(least observable) input that is significant to the measurement in its entirety.

Equity-Based
Compensation

The  Partnership  awards  equity-based  compensation  to  officers,  directors  and  employees  under  the  Long-Term  Incentive  Plan.  All  equity-based  awards  to
officers, directors and employees under the Long-Term Incentive Plan, including grants of performance units, time-based phantom units (phantom units) and time-
based restricted units (restricted units) are recognized in the Consolidated Statements of Income based on their fair values. The fair value of the phantom units and
restricted units are based on the closing market price of the Partnership’s common unit on the grant date. The fair value of the performance units is estimated on the
grant date using a lattice-based valuation model that factors in information, including the expected distribution yield, expected price volatility, risk-free interest rate
and the probable outcome of the market condition, over the expected life of the performance units. Compensation expense for the phantom unit and restricted unit
awards is a fixed amount determined at the grant date fair value and is recognized as services are rendered by employees over a vesting period. The vesting of the
performance  unit awards is also contingent  upon the probable  outcome of the market  condition. Depending on forfeitures  and actual  vesting, the compensation
expense recognized related to the awards could increase or decrease.

Employee
Benefit
Plans

On January 1, 2015, the Partnership adopted the 401(k) Savings Plan, covering all full-time employees. Participant contributions are discretionary, and can be
up to 70% of compensation, as pre-tax, Roth, and /or after-tax contributions, subject to certain limits. We match 100% of employee contributions up to 6% of each
participant’s eligible annual compensation, subject to certain limits. Matching contributions provided by the Partnership are immediately vested. The Partnership
may also make discretionary profit sharing contributions. Allocations of such profit sharing contributions are based on the proportion of each participant's eligible
compensation of the plan year to the total of all participants' eligible compensation, as defined. A participant must be employed on the last day of the Plan year in
order to receive an allocation of profit sharing contributions. Profit sharing contributions must be approved by the Board of Directors annually. For the years ended
December 31, 2018 , 2017 and 2016 , the Partnership contributed $19 million , $18 million and $16 million , respectively.

During  the  years  ended  December  31, 2018  , 2017 and 2016 ,  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. For the
years ended December 31, 2018 , 2017 and 2016 , the Partnership reimbursed OGE Energy $3 million , $5 million and $7 million , respectively, for these benefits.
See Note 15 for further information related to our related party transactions.

On November  14, 2017, the  General  Partner  adopted  the Fifth  Amended  and Restated  Agreement  of  Limited  Partnership  (the  Partnership  Agreement),  to
implement certain changes to the Internal Revenue Code enacted by the Bipartisan Budget Act of 2015 relating to partnership audit and adjustment procedures.
The Partnership Agreement also removed references to the subordinated units (all of which previously converted into common units) and related provisions.

(2) New Accounting Pronouncements

Accounting
Standards
to
be
Adopted
in
Future
Periods

Leases

In February 2016, the FASB issued ASU 2016-02, “Leases (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.

96

Table of Contents

In January 2018, the FASB issued ASU 2018-01, “Land Easement Practical Expedient for Transition to Topic 842.” This standard permits an entity to elect
an  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 intends to elect this transition provision.

In July 2018, the FASB issued ASU No. 2018-10, “Codification Improvements to Topic 842, Leases” to address implementation issues that could arise as

organizations comply with ASC 842.

In July 2018, the FASB issued ASU No. 2018-11, “Leases (Topic 842) - Targeted Improvements” to assist stakeholders with implementation questions and
issues as organizations prepare to adopt ASC 842. These questions and issues relate primarily to (1) comparative reporting requirements for initial adoption; and
(2) for lessors only, separating lease and non-lease components in a contract and allocating the consideration in the contract to the separate components.

In December 2018, the FASB issued ASU No. 2018-20, “Leases (Topic 842) - Narrow-Scope Improvements for Lessors” to address stakeholders’ concerns
regarding: (1) sales taxes and similar taxes collected from lessees; (2) certain lessor costs paid directly by lessees; and (3) recognition of variable payments for
contracts with lease and non-lease components.

Based upon the Partnership’s continuing assessment of contracts and easements relative to the provisions of the ASU No. 2016-02 lease standard, the ASU
No. 2018-01 easement standard, the ASU No. 2018-10 codification improvements standard, the ASU No. 2018-11 targeted improvements standard and ASU No.
2018-20  improvements  for  lessors  standard,  the  Partnership  anticipates  the  adoption  of  ASC  No.  842  will  increase  our  asset  and  liability  balances  on  the
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 are currently classified as operating leases. We continue to develop the underlying reports, internal controls and disclosures to record activity under
Topic 842 upon adoption. The Partnership adopted Topic 842 on January 1, 2019 on a retrospective basis as of that date. Upon adoption, the Partnership did not
recognize a material cumulative adjustment to the Consolidated Statement of Partners’ Equity and we do not expect any material changes in the timing of expense
recognition or our accounting policies.

Financial Instruments—Credit Losses

In  June  2016,  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, 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  standard  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 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 Consolidated
Financial Statements and related disclosures.

Compensation—Stock Compensation

In June 2018, the FASB issued ASU No. 2018-07, “Compensation-Stock Compensation (Topic 718): Improvements to Non-employee Share-Based Payment
Accounting.” This standard requires entities to include share-based payment transactions for acquiring goods and services from non-employees. The standard is
effective  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 Consolidated Financial Statements and related disclosures.

Fair Value Measurement—Disclosure Framework-Changes to the 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

97

Table of Contents

notes to the financial statements by facilitating clear communication of the information required by GAAP that is most important to users of each entity’s financial
statements.  The  standard  is  effective  for  interim  and  annual  reporting  periods  beginning  after  December  15,  2019,  although  early  adoption  is  permitted.  The
Partnership  expects  to  adopt  these  standards  in  the  first  quarter  of  2020  and  continues  to  evaluate  the  other  impacts  of  the  new  standards  on  our  Consolidated
Financial Statements and related disclosures.

Intangibles—Goodwill and Other—Internal-Use Software

In  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 Consolidated Financial Statements and related disclosures.

Derivatives and Hedging

In October 2018, the FASB issued ASU No. 2018-16, “Derivatives and Hedging (Topic 815): Inclusion of the Secured Overnight Financing Rate (SOFR)
Overnight  Index  Swap  (OIS)  Rate  as  a  Benchmark  Interest  Rate  for  Hedge  Accounting  Purposes,”  which  expands  the  list  of  United  States  (U.S.)  benchmark
interest  rates  permitted  in  the  application  of  hedge  accounting.  This  standard  allows  the  use  of  the  Overnight  Index  Swap  (OIS)  Rate  based  on  the  Secured
Overnight  Financing  Rate  (SOFR)  as  a  U.S.  benchmark  interest  rate  for  hedge  accounting  purposes.  The  standard  is  effective  for  interim  and  annual  periods
beginning  after  December  15,  2018.  The  Partnership  does  not  expect  the  adoption  of  this  standard  to  have  material  impact  on  our  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 Consolidated Financial Statements and related disclosures.

(3) Revenues

The  Partnership  adopted  ASU  No.  2014-09,  “Revenue  from  Contracts  with  Customers”  (ASC  606)  on  January  1,  2018  using  the  modified  retrospective
method. Upon adoption, the Partnership did not recognize a material cumulative adjustment to Partners’ Equity and there were no material changes in the timing of
revenue recognition or our accounting policies. The Partnership has applied the standard to only contracts that were not expired as of January 1, 2018.

Natural Gas, NGLs or Condensate

We deliver natural gas, NGLs and condensate to purchasers at contractually agreed-upon delivery points at which the purchaser takes custody, title, and risk
of  loss  of  the  commodity.  We  recognize  revenue  when  control  transfers  to  the  purchaser  at  the  delivery  point  based  on  the  contractually  agreed  upon  fixed  or
index-based price received.

Gain (Loss) on Derivative Activity

Included  in  Product  sales  are  gains  and  losses  on  natural  gas,  natural  gas  liquids,  and  crude  oil  (for  condensate)  derivatives  that  are  accounted  for  under

guidance in ASC 815. See Note 12 for further discussion of our derivative and hedging activity.

Service
Revenues

Service revenues include demand revenues and volume-dependent revenues, both of which include contracts with customers that may contain performance
obligations that are settled over time. For these types of contracts with customers, service revenue is recognized when the right to invoice has been met, which is in
accordance with our election to use the right to invoice practical expedient.

Demand revenues

Our demand revenue arrangements are generally structured in one of the following ways:

•

•

Under  a  firm  arrangement,  a  customer  agrees  to  pay  a  fixed  fee  for  a  contractually  agreed  upon  pipeline  or  storage  capacity,  which  results  in
performance obligations for each individual period of reservation. Once the services have been completed, or the customer no longer has access to
the contracted capacity, revenue is recognized.

Under a minimum volume commitment arrangement, a customer agrees to pay the contractually agreed upon gathering, compressing and treating
fees for a minimum volume of natural gas or crude oil irrespective of whether or not the minimum volume of natural gas or crude oil is delivered,
which results in performance obligations for each individual unit of volume. If the actual volumes exceed the minimum volume of natural gas or
crude oil, the customer pays the contractually agreed upon gathering, compressing and treating fees for the excess volumes in

Table of Contents

addition to the fees paid for the minimum volume of natural gas or crude oil. Certain of our contracts provide our customers the option to elect to
pay  a  higher  gathering  fee  over  the  remaining  term  of  the  contract  in  lieu  of  making  a  contractually  agreed  upon  shortfall  payment.  Once  the
services have been completed, or the customer no longer has the ability to utilize the services, the performance obligation is met, and revenue is
recognized.  In  addition,  when  certain  minimum  volume  commitment  fee  arrangements  include  commitments  of  one  year  or  more,  significant
judgment  is  used  in  interim  commitment  periods  in  which  a  customer’s  actual  volumes  are  deficient  in  relation  to  the  minimum  volume
commitment.  Revenue  is  recognized  in  proportion  to  the  pattern  of  past  performance  exercised  by  the  customer  or  when  the  likelihood  of  the
customer meeting the minimum volume commitment becomes remote.

Volume-dependent revenues

Our volume-dependent  revenues  primarily  consist  of gathering,  compressing,  treating,  processing,  transportation  or storage  services  fees  on contracts  that
exceed  their  contractually  committed  volume  or  do  not  have  firm  arrangements  or  minimum  volume  commitment  arrangements.  These  fees  are  dependent  on
throughput  by  third  party  customers,  which  results  in  performance  obligations  for  each  individual  unit  of  volume  and  revenue  is  recognized  as  the  service  is
performed.  Our  other  fee  revenue  arrangements  have  pricing  terms  that  are  generally  structured  in  one  of  the  following  ways:  (1)  Contractually  agreed  upon
monetary fee for service or (2) contractually agreed upon consideration received in the form of natural gas or natural gas liquids, which are valued at the current
month index-based price, which approximates fair value.

Accounts Receivable

Payments for all types of revenues are typically received within 30 days of invoice. Invoices for all revenue types are sent on at least a monthly basis, except
for  the  shortfall  provisions  under  certain  minimum  volume  commitment  arrangements,  which  are  typically  invoiced  annually.  Accounts  receivable  includes
accrued revenues associated with certain minimum volume commitments that will be invoiced at the conclusion of the measurement period specified under the
respective contracts.

(1) Contract assets reflected in Total Accounts Receivable include accrued minimum volume commitments. Contract assets decreased $21 million compared to January 1,
2018 due to increased throughput on certain minimum volume commitment arrangements resulting in lower recognized contract assets as of December 31, 2018 . Total
Accounts Receivable does not include $3 million of contract assets related to firm transportation contracts with tiered rates, which are reflected in Other Assets.

(2) Total Accounts Receivable includes Accounts receivables, net of allowance for doubtful accounts and Accounts receivable—affiliated companies.

Contract Liabilities

Our contract liabilities primarily consist of the following prepayments received from customers for which the good or service has not yet been provided in

connection with the prepayment:

•

•

Under  certain  firm  arrangements,  customers  pay  their  demand  fee  prior  to  the  month  of  contracted  capacity.  These  fees  are  applied  to  the
subsequent month’s activity and are included in other current liabilities on the Consolidated Balance Sheets.

Under certain demand and volume dependent arrangements, customers make contributions of aid in construction payments. For payments that are
related to contracts under ASC 606, the payment is deferred and amortized over the life of the associated contract and the unamortized balance is
included in other current or long-term liabilities on the Consolidated Balance Sheets.

Impact of Adoption

Upon adoption of ASC 606, the recognition of revenues for certain contractual arrangements was impacted as follows:

•

•

•

•

Natural gas and natural gas liquids purchase arrangements - For certain arrangements within our gathering and processing segment, the Partnership
purchases and controls the entire hydrocarbon stream at the point of receipt. As of January 1, 2018, these arrangements are considered supplier
contracts rather than contracts with customers. Therefore, beginning January 1, 2018, the gathering and processing fees for these arrangements that
were previously recognized as Service revenues under ASC 605 are recognized as reductions to Cost of natural gas and natural gas liquids.

Percent-of-proceeds and percent-of-liquids processing arrangements - Under percent-of-proceeds and percent-of-liquids arrangements within our
gathering  and  processing  segment,  the  Partnership  has  previously  recognized  the  value  of  natural  gas  and  natural  gas  liquids  received  in  our
purchase cost within Cost of natural gas and natural gas liquids. As of January 1, 2018, the Partnership recognizes the value of the natural gas and
NGLs received as Service revenues and as an increase to Cost of natural gas and natural gas liquids when the natural gas or NGLs are sold and
Product sales are recognized.

Keep-whole  arrangements  -  Under  keep-whole  arrangements  within  our  gathering  and  processing  segment,  the  Partnership  has  previously
recognized the value of NGLs received in Product sales and the value of the thermally equivalent quantity of natural gas provided in our purchase
cost within Cost of natural gas and natural gas liquids. As of January 1, 2018, the Partnership recognizes the value of the NGLs received less the
value  of  the  thermally  equivalent  volume  of natural  gas provided  as  Service  revenues  and  as an increase  to Cost of  natural  gas and  natural  gas
liquids when the NGLs are sold and Product sales are recognized.

Fixed  fuel  arrangements  -  Under  certain  gathering  arrangements  within  our  gathering  and  processing  segment  as  well  as  under  certain
transportation  arrangements  within  our  transportation  and  storage  segment  we  receive  a  fixed  amount  of  fuel  regardless  of  actual  fuel  usage.
Previously, revenue for fuel in excess of actual usage was recognized when such fuel was received, and additional revenue was recognized when
such fuel was sold. As of January 1, 2018, fuel in excess of actual usage is treated as a byproduct obtained through the fulfillment of a contract, and

101

 
 
 
 
 
   
   
 
 
 
 
 
 
 
 
   
   
   
   
 
 
 
 
 
 
 
 
   
   
   
   
 
Table of Contents

the Partnership will recognize revenue at the time the excess fuel is sold. This results in a reduction of Product sales and a corresponding reduction
in Cost of natural gas and natural gas liquids.

•

Natural gas and natural gas liquids sales arrangements  - For certain arrangements  within our gathering and processing segment, the Partnership
sells  the  entire  hydrocarbon  stream  at  the  point  of  delivery  to  a  third-party  processing  facility.  As  of  January  1,  2018,  these  arrangements  are
considered  sales  once  control  has  transferred  to the  third-party  processing  facility.  Therefore,  beginning  January  1, 2018, the costs  and fees  for
these  arrangements  that  were  previously  recognized  as  a  component  of  cost  of  gas  and  natural  gas  liquids,  are  recognized  as  reductions  to  the
transaction price under ASC 606.

(4) Acquisitions

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 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 are included in General and administrative expense in the Consolidated Statements of Income. The Partnership determined not to include pro
forma consolidated financial statements for the periods presented as the impact would not be material.

Align Midstream, LLC Acquisition

On October  4, 2017, the Partnership  acquired  all  of the equity  interests  in Align Midstream,  LLC, now Enable Texola  Gathering and Processing,  LLC, a
midstream  service  provider  with  natural  gas  gathering  and  processing  facilities  in  the  Cotton  Valley  and  Haynesville  plays  of  the  Ark-La-Tex  Basin,  for
approximately $298 million in cash. The acquisition was accounted for as a business combination and funded with borrowings under the Revolving Credit Facility.
During the fourth quarter of 2017, the Partnership finalized the purchase price allocation as of October 4, 2017.

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

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 10 years. Goodwill recognized from the acquisition primarily relates to greater operating leverage in the Ark-
La-Tex Basin and is allocated to the gathering and processing segment. The Partnership incurred approximately $2 million of acquisition costs associated with this
transaction, which are included in General and administrative expense in the Consolidated Statements of Income. The Partnership determined not to include pro

(5) Earnings Per Limited Partner Unit

Basic and diluted earnings per limited partner unit is calculated by dividing net income allocable to common and subordinated unitholders by the weighted
average number of common and subordinated units outstanding during the period. Any common units issued during the period are included on a weighted average
basis  for the days  in which they were  outstanding.  The dilutive  effect  of the unit-based  awards discussed  in  Note 18 was  $0.01 per unit during the year ended
December 31, 2018 and less than $0.01 per unit during the years ended December 31, 2017 and 2016 .

(1) The board of directors of Enable GP declared this $0.625 per Series A Preferred Unit cash distribution on February 8, 2019 , which was paid on February 14, 2019 to

Series A Preferred unitholders of record at the close of business on February 8, 2019 .

(2) The  prorated  quarterly  distribution  for  the  Series  A  Preferred  Units  is  for  a  partial  period  beginning  on  February  18,  2016,  and  ending  on  March  31,  2016,  which

equates to $0.625 per unit on a full-quarter basis or $2.50 per unit on an annualized basis.

General
Partner
Interest
and
Incentive
Distribution
Rights

Enable GP owns a non-economic general partner interest in the Partnership and, except as provided below with respect to incentive distribution rights, 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

Prior to the expiration of the subordination period, CenterPoint Energy and OGE Energy held 139,704,916 and 68,150,514 subordinated units, respectively.
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;

Table of Contents

•
•

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.

ATM
Program

On  May  12,  2017,  the  Partnership  entered  into  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. For the year ended  December 31, 2018 , the Partnership
issued 140,920 common units under the ATM Program, which generated proceeds of approximately $2 million (net of approximately $25,000 of commissions).
For the year ended December 31, 2017 , the Partnership issued 18,500 units under the ATM Program, which generated proceeds of approximately $303,000 (net of
approximately $3,000 of  commissions).  The  proceeds  were  used  for  general  partnership  purposes.  As  of  December  31,  2018  , $197  million  of  common  units
remained available for issuance through the ATM Program.

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.

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 for the years ended December 31, 2018 and 2017 . 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 limited partner 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 our 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.  During  the  years  ended
December  31,  2018  ,  2017  and  2016  ,  the  Partnership  billed  SESH  $18  million  ,  $17  million  and  $13  million  ,  respectively,  associated  with  these  service
agreements.

Commercial
Paper

The  Partnership  has  a  commercial  paper  program,  pursuant  to  which  the  Partnership  is  authorized  to  issue  up  to  $1.4  billion  of  commercial  paper.  The
commercial  paper  program  is  supported  by  our  Revolving  Credit  Facility,  and  outstanding  commercial  paper  effectively  reduces  our  borrowing  capacity
thereunder.  There  were  $649  million  and  $405  million  outstanding  under  our  commercial  paper  program  at  December  31,  2018  and  December  31,  2017  ,
respectively. The weighted average interest rate for the outstanding commercial paper was 3.40% as of December 31, 2018 .

Revolving
Credit
Facility

On April  6,  2018,  the  Partnership  amended  and  restated  its  Revolving  Credit  Facility.  As amended  and  restated,  the 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 , in aggregate. The Revolving Credit Facility is scheduled to mature

on  April  6,  2023,  subject  to  an  extension  option,  which  may  be  exercised    two  times  to  extend  the  term  of  the  Revolving  Credit  facility,  in  each  case,  for  an
additional  one -year term. As of December 31, 2018 , there were $250 million principal advances and $3 million in letters of credit outstanding under the restated
Revolving Credit Facility.

The Revolving Credit Facility provides that outstanding borrowings bear interest at 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 applicable credit ratings. As of December 31, 2018 , 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  applicable  credit  rating  from  the  rating  agencies.  As  of
December 31, 2018 , the commitment fee under the 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 Consolidated Statements of Income.

The Revolving Credit Facility contains a financial covenant requiring us to maintain a ratio of consolidated funded debt to consolidated EBITDA as defined
under  the  Revolving  Credit  Facility  as  of  the  last  day  of  each  fiscal  quarter  of  less  than  or  equal  to  5.00 to  1.00;  provided  that,  for  any  three  fiscal  quarters
including and following any fiscal quarter in which the aggregate value of one or more acquisitions by us or certain of our subsidiaries with a purchase price of at
least $25 million in the aggregate, the consolidated funded debt to consolidated EBITDA ratio as of the last day of each such fiscal quarter during such period
would be permitted to be up to 5.50 to 1.00.

The Revolving Credit Facility also contains covenants that restrict us and certain subsidiaries in respect of, among other things, mergers and consolidations,
sales of all or substantially all assets, incurrence of subsidiary indebtedness, incurrence of liens, transactions with affiliates, designation of subsidiaries as Excluded
Subsidiaries  (as  defined  in  the  Revolving  Credit  Facility),  restricted  payments,  changes  in  the  nature  of  their  respective  businesses  and  entering  into  certain
restrictive agreements. Borrowings under the Revolving Credit Facility are subject to acceleration upon the occurrence of certain defaults, including, among others,
payment defaults on such facility,  breach of representations,  warranties and covenants, acceleration  of indebtedness  (other than intercompany and non-recourse
indebtedness)  of  $100  million  or  more  in  the  aggregate,  change  of  control,  nonpayment  of  uninsured  money  judgments  in  excess  of  $100  million  and  the
occurrence of certain ERISA and bankruptcy events, subject where applicable to specified cure periods.

2015
Term
Loan
Agreement

On  July  31,  2015,  the  Partnership  entered  into  a  term  loan  facility,  providing  for  an  unsecured  three -year $450 million term loan agreement,  which was
scheduled to mature on July 31, 2018. The 2015 Term Loan Agreement is included as Current portion of long-term debt in the Partnership’s Consolidated Balance
Sheets as of December 31, 2017. In May 2018, we used a portion of the proceeds from the issuance of the 2028 Notes to repay all amounts outstanding under the
2015 Term Loan Agreement.

Senior
Notes

On  May  10,  2018,  the  Partnership  completed  the  public  offering  of  $800  million  aggregate  principal  amount  of  its  4.95% Senior  Notes  due  2028.  The
Partnership  received  net  proceeds  of  approximately  $787  million  .  The  proceeds  were  used  for  general  partnership  purposes,  including  to  repay  all  amounts
outstanding  under the 2015 Term  Loan Agreement,  as well as amounts  outstanding  under the  commercial  paper  program. The 2028 Notes had an unamortized
discount of $6 million and unamortized debt expense of $7 million at December 31, 2018 , resulting in an effective interest rate of 5.21% during the year ended
December 31, 2018 .

In addition to the 2028 Notes, as of December 31, 2018 , the Partnership’s debt included the 2019 Notes, 2024 Notes, 2027 Notes and 2044 Notes, which had
$2 million of unamortized discount and $13 million of unamortized debt expense at December 31, 2018 , resulting in effective interest rates of 2.57% , 4.02% ,
4.58% and 5.08% , respectively, during the year ended December 31, 2018 .

The  indenture  governing  the  2019  Notes,  2024  Notes,  2027  Notes,  2028  Notes  and  2044  Notes  contains  certain  restrictions,  including,  among  others,

(12) 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 swaptions are used to manage the Partnership’s NGL and condensate
exposure associated with its processing agreements;
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  assets,  contracts  and  asset  management
activities.

Normal purchases and normal sales contracts are not recorded in Other Assets or Liabilities in the 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 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 are recorded as Other Assets or Liabilities in the Consolidated Balance Sheets at fair value on a net basis with such
amounts classified as current or long-term based on their anticipated settlement.

As of December 31, 2018 and 2017 , the Partnership had no derivative instruments that were designated as cash flow or fair value hedges for accounting

purposes.

Credit
Risk

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
as
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.

In  the  event  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 which could include letters or 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  December 31, 2018 , under these
obligations, the Partnership has posted no cash collateral related to NGL swaps and crude oil swaps and swaptions and no 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.

(13) Fair Value Measurements

Certain assets and liabilities are recorded at fair value in the 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  NYMEX  or  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 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
December 31, 2018 , 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 period ended December 31, 2018 , all instruments previously classified as Level 3 were transferred to Level 2 as the inputs for these
liabilities became observable for classification in Level 2.

Table of Contents

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.

was outstanding as of December 31, 2018 and 2017 , respectively.

The fair value of the Partnership’s Revolving Credit Facility, 2015 Term Loan Agreement, 2019 Notes, 2024 Notes, 2027 Notes, 2028 Notes, 2044 Notes,
and EOIT Senior Notes, is based on quoted market prices and estimates of current rates available for similar issues with similar maturities and is classified as Level

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).

During the year ended December 31, 2016, the Partnership remeasured the Service Star assets at fair v alue and reassessed the carrying value of the Service
Star business line, a component of the gathering and processing segment that provides measurement and communication services to third parties. The impairment,
which  impaired  substantially  all  of  the  remaining  net  book  value  of  the  Service  Star  business  line,  was  primarily  driven  by  the  impact  of  planned  technology
changes affecting Service Star. Based on forecasted future undiscounted cash flows management determined that the carrying value of the Service Star assets were
not fully recoverable. The Partnership utilized the income approach (generally accepted valuation approach) to estimate the fair value of these assets. The primary
inputs are forecasted cash flows and the discount rate. The fair value measurement is based on inputs that are not observable in the market and thus represent level
3 inputs. Applying a discounted cash flow model to the property, plant and equipment and reviewing the associated materials and supplies inventory, during the
year ended December 31, 2016, the Partnership recognized a $9 million impairment. The impairment consisted of an $8 million write-down of property, plant and
equipment and a $1 million write-down of materials and supplies inventory considered either excess or obsolete.

Based  upon  review  of  forecasted  undiscounted  cash  flows  as  of  December  31,  2018  ,  all  of  the  asset  groups  were  considered  recoverable.  Future  price
declines,  throughput  declines,  contracted  capacity  declines,  cost  increases,  regulatory  or  political  environment  changes  and  other  changes  in  market  conditions
could reduce forecasted undiscounted cash flows.

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  Consolidated  Balance
Sheets. The Partnership has presented the fair values of its derivative contracts under master netting agreements using a net fair value presentation.

(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. There were no netting adjustments as of December 31, 2018 and 2017 .

(2) Gas imbalance assets exclude fuel reserves for under retained fuel due from shippers of $11 million and $10 million at December 31, 2018 and 2017 , 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 $5 million and none at December 31, 2018 and 2017 , respectively, which fuel

services are in effect through May 15, 2023 and will remain in effect unless and until terminated by either party upon twelve months’ prior written notice.

The Partnership may agree to reimburse the costs that its customers incur to make required modifications for the repair and maintenance of pipelines that
impact customer delivery points. For the year ended December 31, 2018 , we reimbursed CenterPoint Energy’s LDCs $1 million in connection with receipt facility
modifications that were necessitated by the repair and maintenance of our pipelines and in connection with a reimbursement associated with an unplanned pipeline
outage. For the year ended December 31, 2017 , we reimbursed CenterPoint Energy’s LDCs $1 million in connection with receipt facility modifications that were
necessitated by the repair and maintenance of our pipelines.

Transportation and Storage Agreement with OGE Energy

EOIT  provides  no-notice  load-following  transportation  and  storage  services  to  OGE  Energy.  On  March  17,  2014,  EOIT  entered  into  a  transportation
agreement with OGE Energy for four of its generating facilities, with a primary term of May 1, 2014 through April 30, 2019. On October 24, 2018, EOIT entered

The Partnership receives services and support functions from each of CenterPoint Energy and OGE Energy under service agreements for an initial term that
ended on April 30, 2016. The service 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  these  service  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 2018 are $4
million and $1 million , respectively.

The Partnership leases office and data center space from an affiliate of CenterPoint Energy in Shreveport, Louisiana. The term of the lease was effective on
October  1,  2016  and  extends  through  December  31,  2019.  As  of  December  31,  2018  ,  the  Partnership  expects  to  incur  approximately  $1  million  in  rent  and
maintenance expenses under the lease during the remaining term of the lease.

During  the  years  ended  December  31, 2018  , 2017 and 2016 ,  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 a cap of $5 million in 2018 and thereafter, unless and until secondment is terminated.

Amounts  charged  to  the  Partnership  by  affiliates  for  seconded  employees,  an  operating  lease  and  corporate  services,  included  primarily  in  Operation  and

Total rental expense for all operating leases was $35 million , $27 million and $27 million during the years ended December 31, 2018 , 2017 and 2016 ,

respectively.

The Partnership currently occupies 162,053 square feet of office space at its principle executive offices under a lease that expires June 30, 2019 . The lease
payments  are  $19  million  over  the  lease  term,  which  began  April  1,  2012.  These  lease  expenses  are  included  in  General  and  administrative  expense  in  the
Consolidated Statements of Income.

During 2017 , the Partnership entered into a lease to occupy 48,642 square feet of office space in Houston, Texas, which ends December 31, 2025. The lease
payments  are  $4  million  over  the  lease  term,  as  well  as  a  proportionate  percentage  of  facility  expenses.  These  lease  expenses  are  included  in  General  and
administrative expense in the Consolidated Statements of Income.

On  August  28,  2018,  the  Partnership  entered  into  the  Bank  of  Oklahoma  Park  Plaza  lease  to  occupy  154,584  feet  of  office  space  in  Oklahoma  City,
Oklahoma,  which  ends  June  30, 2029  .  The  lease  payments  commence  on  July  1,  2019,  and  total  $  25  million  over  the  lease  term,  as  well  as  a  proportionate
percentage of facility expenses. The Partnership will relocate its headquarters to the new location during the third quarter of 2019. Minimum lease payments are
expected to be $1 million in 2019 and $2 million per year from 2020 through 2023 .

The Partnership  currently  has 110 compression service agreements, of which 46 agreements are on a month-to-month basis, 60 agreements will expire in
2019 and four agreements 2020 . The Partnership also has seven gas treating lease agreements, all of which are on a month-to-month basis. These lease expenses
are reflected in Operation and maintenance expense in the Consolidated Statements of Income.

Commercial Obligations

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,  LP  for  400 MMcf/d  of  deliveries  to  the  Godley  Plant  in  Johnson  County,  Texas.  As  of  December  31,  2018  ,  the  Partnership  estimates  the
remaining associated 10 -year minimum volume commitment fee to be $215 million in the aggregate. Minimum volume commitment fees are expected to be $23
million per year from 2019 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 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.

Legal,
Regulatory
and
Other
Matters

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.

(17) Income Taxes

The Partnership’s earnings are generally not subject to income tax ( other than Texas state margin taxes and taxes associated with the Partnership’s corporate
subsidiary Enable Midstream Services) and are taxable at the individual partner level. The Partnership and its non-corporate subsidiaries are pass-through entities
for federal income tax purposes. For these entities, all income, expenses, gains, losses and tax credits generated flow through to their owners and, accordingly, do
not result in a provision for income taxes in the consolidated financial statements. Consequently, the Consolidated Statements of Income do not include an income
tax provision (other than Texas state margin taxes and taxes associated with the Partnership’s corporate subsidiary). On December 22, 2017, the act known as the
“Tax Cuts and Jobs Act,” was signed into law which lowered the corporate tax rate from 35% to 21% for tax years beginning after December 31, 2017. As a result
of  this  new  law,  the  Partnership’s  corporate  subsidiaries  re-valued  their  deferred  income  tax  assets  and  liabilities  as  of  December  31,  2017,  which  resulted  in
recording a federal deferred income tax benefit of $1 million for the year ended December 31, 2017.

The items comprising income tax expense are as follows:

(18) Equity-Based Compensation

Enable GP has adopted the Enable Midstream Partners, LP Long Term Incentive Plan (LTIP) for officers, directors and employees of the Partnership and its
affiliates,  including  any  individual  who  provides  services  to  the  Partnership  as  a  seconded  employee  .  The  LTIP  provides  for  the  following  types  of  awards:
restricted units, phantom units, appreciations rights, option rights,

Table of Contents

cash incentive awards, performance units, distribution equivalent rights, and other awards denominated in, payable in, valued in or otherwise based on or related to
common units.

The LTIP is administered by the Compensation Committee of the Board of Directors. With respect to any grant of equity as long-term incentive awards to
our independent directors and our officers subject to reporting under Section 16 of the Exchange Act, the Compensation Committee makes recommendations to the
Board  of  Directors  and  any  such  awards  will  only  be  effective  upon  the  approval  of  the  Board  of  Directors.  The  LTIP  limits  the  number  of  units  that  may  be
delivered pursuant to vested awards to 13,100,000 common units, subject to proportionate adjustment in the event of unit splits and similar events. Common units
cancelled, forfeited, expired or cash settled are available for delivery pursuant to other awards.

The Board of Directors may terminate or amend the long-term incentive plan at any time with respect to any units for which a grant has not yet been made,
including amending the long-term incentive plan to increase the number of units that may be granted subject to the requirements of the exchange upon which the
common units are listed at that time. However, no change in any outstanding grant may be made that would be adverse to the participant without the consent of the
participant.

Performance  unit,  restricted  unit  and  phantom  unit  awards  are  classified  as  equity  on  the  Partnership’s  Consolidated  Balance  Sheet.  The  following  table
summarizes the Partnership’s equity-based compensation expense for the years ended December 31, 2018 , 2017 and 2016 related to performance units, restricted
units and phantom units for the Partnership’s employees and independent directors:

Awards of performance based phantom units (performance units) have been made under the LTIP in 2018 , 2017 and 2016 to certain officers and employees
providing services to the Partnership. Subject to the achievement of performance goals, the performance unit awards cliff vest three years from the grant date, with
distribution equivalent rights paid at vesting. The performance goals for 2018 , 2017 and 2016 awards are based on total unitholder return over a three -calendar
year performance cycle. Total unitholder return is based on the relative performance of the Partnership’s common units against a peer group. The performance unit
awards have a payout from zero to 200% of the target based on the level of achievement of the performance goal. Performance unit awards are paid out in common
units,  with  distribution  equivalent  rights  paid  in  cash  at  vesting.  Any  unearned  performance  units  are  cancelled.  Pay  out  requires  the  confirmation  of  the
achievement of the performance level by the Compensation Committee. Prior to vesting, performance units are subject to forfeiture if the recipient’s employment
with the Partnership is terminated for any reason other than death, disability, retirement or termination other than for cause within two years of a change in control.
In the event of retirement, a participant will receive a prorated payment based on the target performance, rather than actual performance, of the performance goals
during the award cycle.

The fair value of each performance unit award was estimated on the grant date using a lattice-based valuation model. The valuation information factored into
the  model  includes  the  expected  distribution  yield,  expected  price  volatility,  risk-free  interest  rate  and  the  probable  outcome  of  the  market  condition  over  the
expected life of the performance units. Equity-based compensation expense for each performance unit award is a fixed amount determined at the grant date fair
value  and  is  recognized  over  the  three -year  award  cycle  regardless  of  whether  performance  units  are  awarded  at  the  end  of  the  award  cycle.  Distributions  are
accumulated and paid at vesting and, therefore, are included in the fair value calculation of the performance unit award. The expected price volatility for the awards
granted in 2018 and 2017 is based on three years of daily stock price observations, to determine the total unitholder return ranking. The expected price volatility for
the awards granted in 2016 is based on two years of daily stock price observations, combined with the average of the one -year volatility of the applicable peer
group companies used to determine the total unitholder return ranking. The risk-free interest rate for the performance unit grants is based on the three -year U.S.
Treasury yield curve in effect at the time of the grant. There are no post-vesting restrictions related to the Partnership’s performance units.

Awards of phantom units have been made under the LTIP in 2018 , 2017 and 2016 to certain officers and employees providing services to the Partnership
and certain directors of Enable GP. Phantom units vest on the first, second or third anniversary of the grant date with distribution equivalent rights paid during the
vesting  period.  Phantom  unit  awards  are  paid  out  in  common  units,  with  distributions  equivalent  rights  paid  in  cash.  Phantom  units  cliff-vest  at  the  end  of  the
vesting  period.  Any  unearned  phantom  units  are  cancelled.  Prior  to  vesting,  phantom  units  are  subject  to  forfeiture  if  the  recipient’s  employment  with  the
Partnership is terminated for any reason other than death, disability, retirement or termination other than for cause within two years of a change in control.

The fair value of the phantom units was based on the closing market price of the Partnership’s common unit on the grant date. Equity-based compensation
expense for the phantom unit is a fixed amount determined at the grant date fair value and is recognized as services are rendered by employees over the vesting
period. Distributions on phantom units are paid during the vesting period and, therefore, are included in the fair value calculation. The expected life of the phantom
unit is based on the applicable vesting period. The number of phantom units granted and the grant date fair value are shown in the following table.

(19) 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  wholesale  or  retail  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  described  in Note 1. 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.  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.

Financial data for reportable segments are as follows:

(21) Subsequent Event

On January 29, 2019, the Partnership entered into a term loan facility, providing for an unsecured three -year $1 billion term loan agreement. As of January
31, 2019, there is a principal advance of $200 million outstanding under the 2019 Term Loan Agreement, and a delayed-draw feature permits the Partnership to
borrow up to an additional $800 million within 180 days of the closing date, subject to the terms and conditions of the 2019 Term Loan Agreement. 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 designated ratings from Standard & Poor’s Rating Services,

Moody’s Investor Services and Fitch Ratings. As of January 31, 2019, the applicable margin for LIBOR-based advances under the 2019 Term Loan Facility was
1.25% based on the Partnership’s credit ratings. The 2019 Term Loan Agreement contains substantially the same covenants as the Revolving Credit Facility.

The 2019 Term Loan Agreement requires the Partnership to, starting April 29, 2019 and continuing until the date on which all commitments have expired or
been terminated or the amount available to be drawn is zero, pay a ticking fee on each lender’s unused commitment amount. The ticking fee shall equal 0.125% on
the actual daily amount of such lender’s portion of the unused commitments.

Advances  under  the  2019  Term  Loan  Agreement  are  subject  to  certain  conditions  precedent,  including  the  accuracy  in  all  material  respects  of  certain
representations  and  warranties  and  the  absence  of  any  default  or  event  of  default.  Advances  under  the  2019  Term  Loan  Agreement  may  be  used  to  refinance
indebtedness  outstanding  from  time  to  time  and  for  other  general  corporate  purposes,  including  to  fund  acquisitions,  investments  and  capital  expenditures.
Advances  under the 2019 Term  Loan Agreement  can be prepaid, in whole or in part, at any time  without premium  or penalty,  other than usual and customary
LIBOR breakage costs, if applicable.

The  2019  Term  Loan  Agreement  contains  a  financial  covenant  requiring  the  Partnership  to  maintain  a  ratio  of  consolidated  funded  debt  to  consolidated
EBITDA  as  of  the  last  day  of  each  fiscal  quarter  of  less  than  or  equal  to  5.00 to  1.00;  provided  that,  for  a  certain  period  time  following  an  acquisition  by  the
Partnership or certain of its subsidiaries with a purchase price that when combined with the aggregate purchase price for all other such acquisitions in any rolling
12-month period, is equal to or greater than $25 million , the consolidated funded debt to consolidated EBITDA ratio as of the last day of each such fiscal quarter
during such period would be permitted to be up to 5.50 to 1.00.

The  2019  Term  Loan  Agreement  also  contains  covenant  s  that  restrict  the  Partnership  and  certain  of  its  subsidiaries  in  respect  of,  amoung  other  things,
mergers  and  consolidations,  sales  of  all  or  substantially  all  assets,  incurrenece  of  subisdary  indebtedness,  incurrence  of  liens,  transactions  with  affiliates,
designation of subsidiaries as Excluded Subsidiaries (as defined in the 2019 Term Loan Agreement), restricted payments, changes in the nature of their respective
business  and  entering  into  certain  restrictive  agreements.  The  2019  Term  Loan  Agreement  is  subject  to  acceleration  upon  the  occurrence  of  certain  defaults,
including,  amoung  others,  payment  defaults  on  such  facility,  breach  of  representations,  warranties  and  covenants,  acceleration  of  indebtedness  (  other  than
intercompany and non-recourse indebtedness) of $100 million or more in the aggregate, change of control, nonpayment of uninsured judgements in excess of $100
million , and the occurrence of certain ERISA and bankruptcy events, subject where applicable to specified cure periods.

Item 9A. 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)  or  15d-15(e)  under  the  Securities  Exchange  Act  of  1934,  as  amended  (the  “Exchange  Act”))  as  of
December  31,  2018  .  Based  on  such  evaluation,  our  management  has  concluded  that,  as  of  December  31,  2018  ,  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.

Management’s
Report
on
Internal
Control
Over
Financial
Reporting

Management of the Partnership is responsible for establishing and maintaining adequate internal control over financial reporting (as such term is defined in
Exchange Act Rule 13a-15(f) or 15d-15(f)). The Partnership’s internal control over financial reporting is a process designed under the supervision and with the
participation  of  our  principal  executive  and  principal  financial  officers,  and  effected  by  the  board  of  directors,  management  and  other  personnel,  to  provide
reasonable  assurance  regarding  the  reliability  of  financial  reporting  and  the  preparation  of  the  consolidated  financial  statements  in  accordance  with  generally
accepted accounting principles.

The Partnership’s internal control over financial reporting includes policies and procedures that ( 1) pertain to the maintenance of records that, in reasonable
detail, accurately and fairly reflect the Partnership’s transactions and dispositions of the Partnership’s assets; (2) provide reasonable assurance that transactions are
recorded as necessary to permit preparation of the consolidated financial statements in accordance with generally accepted accounting principles, and that receipts
and  expenditures  of  the  Partnership  are  being  made  only  in  accordance  with  authorization  of  the  Partnership’s  management  and  directors;  and  (3)  provide
reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Partnership’s assets that could have a material
effect on the consolidated financial statements.

Because of its inherent limitations, the Partnership’s internal control over financial reporting may not prevent or detect misstatements. Also, projections of
any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of
compliance with our policies or procedures may deteriorate.

Management assessed the effectiveness of the Partnership’s internal control over financial reporting as of December 31, 2018 , with the participation of our
principal  executive  and  principal  financial  officers,  based  on  the  framework  established  in  Internal  Control—Integrated  Framework  (2013)  issued  by  the
Committee  of  Sponsoring  Organizations  of  the  Treadway  Commission,  or  COSO.  Based  on  this  assessment,  management  concluded  that  the  Partnership
maintained effective internal control over financial reporting as of December 31, 2018 .

Our  independently  registered  public  accounting  firm  that  audited  our  financial  statements  has  issued  an  attestation  report  on  the  effectiveness  of  the

Partnership’s internal control over financial reporting.

Changes
in
Internal
Controls

There were no changes in our internal controls over financial reporting during the quarter ended December 31, 2018 , that have materially affected, or that are

reasonably likely to materially affect, our internal control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors of Enable GP, LLC and
Unitholders of Enable Midstream Partners, LP
Oklahoma City, Oklahoma

Opinion on Internal Control over Financial Reporting

We have audited the internal control over financial reporting of Enable Midstream Partners, LP and subsidiaries (the “Partnership”)
as of December 31, 2018, based on criteria established in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of
the Treadway Commission (COSO). In our opinion, the Partnership maintained, in all material respects, effective internal control over financial reporting as of
December 31, 2018, based on criteria established in Internal Control - Integrated Framework (2013) issued by COSO .

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated financial
statements as of and for the year ended December 31, 2018, of the Partnership and our report dated February 19, 2019, expressed an unqualified opinion on those
financial statements.

Basis for Opinion

The  Partnership’s  management  is  responsible  for  maintaining  effective  internal  control  over  financial  reporting  and  for  its  assessment  of  the  effectiveness  of
internal control over financial reporting, included in the accompanying Management’s Report on Internal Control Over Financial Reporting . Our responsibility is
to express an opinion on the Partnership’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB
and are required to be independent with respect to the Partnership in accordance with the U.S. federal securities laws and the applicable rules and regulations of the
Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance
about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal
control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control
based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable
basis for our opinion.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the
preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial
reporting  includes  those  policies  and  procedures  that  (1)  pertain  to  the  maintenance  of  records  that,  in  reasonable  detail,  accurately  and  fairly  reflect  the
transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of
financial  statements  in  accordance  with  generally  accepted  accounting  principles,  and  that  receipts  and  expenditures  of  the  company  are  being  made  only  in
accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of
unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because  of  its  inherent  limitations,  internal  control  over  financial  reporting  may  not  prevent  or  detect  misstatements.  Also,  projections  of  any  evaluation  of
effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with
the policies or procedures may deteriorate.

from  our  assets),  except  for  indebtedness  or  other  obligations  that  are  made  expressly  non-recourse  to  it.  Our  general  partner  may  therefore  cause  us  to  incur

Directors is comprised of eight directors. CenterPoint Energy and OGE Energy have each appointed two of the directors, have jointly appointed three independent
directors, and have jointly appointed our President and Chief Executive Officer as a director. The NYSE does not require us to have a majority of independent
directors on the Board of Directors. 

In identifying and evaluating both incumbent and new directors of the Board of Directors, CenterPoint Energy and OGE Energy assess their experience and

personal characteristics against the following individual qualifications, which CenterPoint Energy and OGE Energy may modify from time to time:

Advisor  to  the  Chairman,  President  and  Chief  Executive  Officer  of  Spectra  Energy  Corp.  In  his  role,  Mr.  A.  Harris  provided  oversight  and  focus  for  Spectra
Energy Corp’s project execution efforts. From 2009 through 2013, Mr. A. Harris served as Chief Development and Operations Officer of Spectra Energy Corp. In
that dual role, Mr. A. Harris oversaw the company’s strategy, business development, and mergers and acquisitions, as well as project execution, the operations of

Board of Directors

Chairmanship

Under the limited liability company agreement of our general partner, the right to appoint the chairman of the Board of Directors rotates between CenterPoint
Energy and OGE Energy every two years. Sean Trauschke currently serves as chairman of the Board of Directors and was appointed by OGE Energy Corp. to
serve as chairman on May 29, 2017. Mr. Trauschke’s term will expire on May 29, 2019, at which time CenterPoint Energy will have the right to appoint the next
chairman. Although the Board of Directors has no policy with respect to the separation of the offices of chairman of the board and chief executive officer, we do
not  expect  these  positions  to  be  occupied  by  the  same  individual  due  to  the  rotating  chairmanship  provision  in  the  general  partner’s  limited  liability  company
agreement.

Board
Membership

Members of the Board of Directors are appointed by CenterPoint Energy and OGE Energy. Accordingly, unlike holders of common stock in a corporation,
our unitholders have only limited voting rights on matters affecting our business or governance, subject in all cases to any specific unitholder rights contained in
our partnership agreement. CenterPoint Energy and OGE Energy are each entitled to appoint two directors and up to two alternate directors. Directors Scott M.
Prochazka  and  Williams  D.  Rogers  were  appointed  by  CenterPoint  Energy.  Directors  Stephen  E.  Merrill  and  Sean  Trauschke  were  appointed  by OGE  Energy.
Currently, neither CenterPoint Energy nor OGE Energy has appointed any alternate directors.

Each independent director, who is required to meet the independence standards for audit committee members established by the NYSE and the Exchange Act,
and any other directors are appointed by the unanimous agreement of CenterPoint Energy and OGE Energy. Directors Alan N. Harris, Ronnie K. Irani, and Peter
H. Kind are independent directors.

Board
Role
in
Risk
Oversight

Our governance guidelines provide that the Board of Directors is responsible for reviewing the process for assessing the major risks facing us and the options
for their mitigation. This responsibility is largely satisfied by the audit committee, which is responsible for reviewing and discussing with management and our
registered public accounting firm our major risk exposures and the policies management has implemented to monitor such exposures, including our financial risk
exposures and risk management policies.

Committees
of
the
Board
of
Directors

Audit Committee. Peter H. Kind, Alan N. Harris and Ronnie K. Irani serve as the members of the audit committee. Mr. Kind is the current chairman of the

audit committee. The Board of Directors is required to have an audit committee of at least three

136

 
 
Table of Contents

members who meet the independence and experience standards established by the NYSE and the Exchange Act. All of our members of the audit committee meet
these independence and experience standards. In addition, Mr. Kind and Mr. Harris meet the Exchange Act definition of an audit committee financial expert. The
audit  committee  assists  the  Board  of  Directors  in  its  oversight  of  the  integrity  of  our  financial  statements  and  our  compliance  with  legal  and  regulatory
requirements and corporate policies and controls. The audit committee has the sole authority to retain and terminate our independent registered public accounting
firm,  approve  all  auditing  services  and  related  fees  and  the  terms  thereof  and  pre-approve  any  non-audit  services  to  be  rendered  by  our  independent  registered
public accounting firm. The audit committee is also responsible for confirming the independence and objectivity of our independent registered public accounting
firm. Our independent registered public accounting firm has been given unrestricted access to the audit committee.

Conflicts Committee. Peter H. Kind, Alan N. Harris and Ronnie K. Irani serve as the members of the conflicts committee. Mr. Kind is the current chairman of
the conflicts committee. The members of our conflicts committee may not be officers or employees of our general partner or directors, officers or employees of its
affiliates, may not hold an ownership interest in our general partner or its affiliates other than common units or awards under any long-term incentive plan, equity
compensation plan, or similar plan implemented by our general partner or the Partnership, and must meet the independence and experience standards established
by the NYSE and the Exchange Act for audit committee members . All of the members of the conflicts committee meet these standards. The conflicts committee
determines if the resolution of any conflict of interest referred to it by our general partner is in our best interests. There is no requirement that our general partner
seek the approval of the conflicts committee for the resolution of any conflict. Any matters approved by the conflicts committee in good faith are deemed to be
approved by all of our partners and not a breach by our general partner of any duties it may owe us or our unitholders. Any unitholder challenging any matter
approved by the conflicts committee has the burden of proving that the members of the conflicts committee did not believe that the matter was in the best interests
of the Partnership. Moreover, any acts taken or omitted to be taken in reliance upon the advice or opinions of experts such as legal counsel, accountants, appraisers,
management  consultants  and  investment  bankers,  where  our  general  partner  (or  any  members  of  the  Board  of  Directors  including  any  member  of  the  conflicts
committee) reasonably believes the advice or opinion to be within such person’s professional or expert competence, are conclusively presumed to have been done
or omitted in good faith.

Compensation Committee. Alan N. Harris, Scott M. Prochazka and Sean Trauschke serve as the members of the compensation committee. The members of
our compensation committee are not required to meet the independence standards established by the NYSE for compensation committee members. Mr. Harris is
the current chairman of the compensation committee. The Board of Directors has delegated responsibility and authority to the board’s Compensation Committee
for  the  compensation  of  our  named  executive  officers  and  independent  directors.  For  more  information  on  the  role  of  the  Compensation  Committee  and
compensation program for our named executive officers and independent directors, see Item 11. “Executive Compensation”.

Governance
Guidelines

We have adopted Governance Guidelines to assist the Board in the exercise of its responsibilities. To promote open discussion among the non-management
directors  of  our  Board  and  among  the  independent  directors  of  our  Board,  our  Governance  Guidelines  provide  that  the  non-management  directors  will  meet
separately  in  executive  session  periodically  and  that  the  independent  directors  will  meet  separately  in  executive  session  at  least  once  a  year.  Currently,  the
chairman of the Board of Directors presides at the executive sessions of the non-management directors and the chairman of the audit committee presides at the
executive sessions of the independent directors. The Partnership’s definitions of independence are provided in the Partnership’s Governance Guidelines, which are
available under the “Governance” subsection of the “Investors” section of our website at www.enablemidstream.com .

Communications
with
the
Board

Unitholders and other interested parties that wish to communicate with members of our Board of Directors, including the Chairman of the Board, the non-
management directors individually or as a group, or the independent directors individually or as a group, may send correspondence to them in care of the General
Counsel by mail to PO Box 24300, Oklahoma City, Oklahoma 73124-0300 or by email to gc@enablemidstream.com.

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Exchange Act requires our directors, certain officers, persons who own more than 10 percent of a registered class of our equity securities
to file reports with the SEC concerning their holdings of, and certain transactions in, our equity and derivative securities ( e.g. , options, convertible securities and
other securities that derive their value from equity securities). Based solely upon our review of copies of filings from reporting persons, we do not believe that any
of our directors or officers or any persons who own more than 10 percent of a registered class of our equity securities failed to file on a timely basis all of the report
required under Section 16(a) of the Exchange Act, except as follows: Mr. C. Harris inadvertently failed to timely report a grant of 16,078 time vesting phantom
units and the withholding for taxes of 2,829 common units.

Code of Ethics

Our general partner has adopted a Code of Business Conduct and Ethics that applies to the directors, officers of our general partner, the Partnership, and our
subsidiaries. Our general partner has also adopted a Code of Ethics for Senior Financial Officers that applies to our chief executive officer, chief financial officer,
chief accounting officer, treasurer and other persons performing similar functions. We make available free of charge our Code of Business Conduct and Ethics, and
Code  of  Ethics  for  Senior  Financial  Officers,  as  well  as  our  Governance  Guidelines,  related  party  transactions  policy,  audit  committee  charter,  compensation
committee charter and insider trading policy under the “Governance” subsection of the “Investors” section of our website at www.enablemidstream.com .

Item 11. Executive Compensation

Compensation Discussion and Analysis

Overview

In this section, we describe and discuss the principles and policies used in setting the compensation of our named executive officers. Our named executive

officers for the fiscal year ended December 31, 2018 were:

• 

• 

Rodney J. Sailor, President and Chief Executive Officer,

John P. Laws, Executive Vice President, Chief Financial Officer and Treasurer,

•  Deanna J. Farmer, Executive Vice President and Chief Administrative Officer,

• 

Craig S. Harris, Executive Vice President and Chief Operating Officer and

•  Mark C. Schroeder, Executive Vice President and General Counsel.

Objective
and
Design
of
Executive
Compensation
Program

We  strive  to  provide  compensation  that  is  competitive,  both  on  a  total  level  and  in  individual  components,  both  with  our  peers  and  with  other  likely
competitors  for  executive  talent.  By  competitive,  we  mean  that  total  compensation  and  each  element  of  compensation  is  within  what  we  believe  to  be  an
appropriate range of the market level of compensation for similarly situated roles.

Our Compensation Committee bases compensation decisions on principles designed to align the interests of our named executive officers with those of our
unitholders. Our overall compensation philosophy is pay for performance. We seek to motivate our named executive officers to achieve individual and business
performance objectives by designing their compensation packages to align with our values, strategy, and financial results. We believe that our named executive
officers should be rewarded for both the short-term and long-term success of the Partnership and, conversely, be subject to a degree of downside risk in the event
that the Partnership does not achieve its performance objectives. As a result, actual compensation in a given year will vary based on our performance, and to a
lesser  extent,  on qualitative  appraisals  of individual  performance.  We  design  the  compensation  packages  for our named  executive  officers  to have a significant
percentage of their total compensation at risk, thus aligning each of our named executive officers with the short-term and long-term performance objectives of the
Partnership and with the interests of our unitholders.

We maintain benefit programs for our employees, including our named executive officers, with the objective of retaining their services. Our benefits reflect

competitive practices at the time the benefit programs were implemented and, in some cases,

138

Table of Contents

reflect  our  desire  to  maintain  similar  benefits  treatment  for  all  employees  in  similar  positions.  To  the  extent  possible,  we  structure  these  programs  to  deliver
benefits in a manner that is tax efficient to both the recipient and the Partnership. The Compensation Committee intends for its compensation design principles to
protect and promote our unitholders’ interests. We believe our compensation programs are consistent with best practices for sound governance.

Our Executive Compensation Program. The Compensation Committee of our Board of Directors oversees the compensation of our named executive officers,
including base salary and short-term and long-term incentive awards. In addition, the Compensation Committee makes any remaining determinations with respect
to compensation based upon the previous year’s performance. With respect to any grant of equity as long-term incentive awards to our named executive officers,
the Compensation Committee makes recommendations to the Board of Directors, but any such equity grants require the approval of the Board of Directors.

Role of Consultant . To provide advice on the form and amount of compensation for our named executive officers in 2018 , our Compensation Committee
engaged Mercer (US) Inc. (“Mercer”), an independent compensation consulting firm. Mercer’s services included a compensation risk assessment and an analysis
of 2018 base salaries, short-term incentive award targets, and long-term incentive award targets. In order to assist with the assessment of the competitiveness of our
2018 named executive officer compensation, Mercer provided market data from the following peer group companies:

The Compensation Committee reviews and assesses the independence and performance of its consultant in accordance with applicable SEC and NYSE rules
on an annual basis in order to confirm that the consultant is independent and meets all applicable regulatory requirements. Prior to its engagement for 2018 , the
Compensation Committee reviewed the independence of Mercer and determined that it meets all applicable regulatory requirements for independence.

Role of Executive Officers. Of our executive officers, our Chief Executive Officer, Chief Financial Officer and Chief Administrative Officer have roles in
determining  executive  compensation  policies  and  programs.  Our  Chief  Executive  Officer,  Chief  Financial  Officer  and  Chief  Administrative  Officer  work  with
business unit and functional leaders along with our internal compensation staff to provide information to the Board of Directors and the Compensation Committee
to help ensure that our compensation programs support our business strategy and goals. Our Chief Executive Officer also makes preliminary recommendations for
base salary adjustments and short-term and long-term incentive levels for the named executive officers other than himself.

Our Chief Executive Officer and our Chief Administrative Officer also periodically review and recommend specific Partnership performance metrics to be
used  in  awards  under  our  short-term  and  long-term  incentive  plans.  Our  Chief  Executive  Officer  and  our  Chief  Administrative  Officer  work  with  the  various
business units and functional departments to develop these metrics, which are then presented to the Compensation Committee. As noted above, the Compensation
Committee makes final decisions regarding executive compensation, except with respect to awards to our executive officers under our long-term incentive plan.
With  respect  to  such  awards,  the  Compensation  Committee  makes  recommendations  to  the  Board  of  Directors,  and  the  Board  of  Directors  makes  final  award
decisions.

Table of Contents

Elements
of
Compensation

The total annual direct compensation program for our named executive officers consists of three components: (1) base salary; (2) a short-term cash incentive
under our short-term incentive plan, which is based on a percentage of annual base salary; and (3) equity-based grants under our long-term incentive plan, which
are  based  on  a  percentage  of  annual  base  salary.  Under  our  compensation  structure,  the  allocation  between  base  salary,  short-term  incentive  and  long-term
incentive  varies  depending  upon  job  title  and  responsibility  levels.  We  consider  it  generally  appropriate  for  officers  with  more  responsibility  to  have  a  larger
portion of their compensation at risk.

Base Salary. We view base salary as the foundation of total compensation. Base salary recognizes the job being performed and the value of that job in the
competitive market. We design base salaries to attract and retain the executive talent necessary for our continued success and provide an element of compensation
that is not at risk in order to avoid fluctuations in compensation that could distract our named executive officers from the performance of their responsibilities. Any
annual  adjustments  to  the  base  salaries  of  our  named  executive  officers  are  primarily  intended  to  reflect  changes  in  market  data  or  increased  experience and
individual  contribution  of  the  executive.  We  set  and  adjust  base  salaries  using  market  data  from  the  Compensation  Committee’s  consultant,  and  we  target  a
reasonable range around the market median for each position, depending on the circumstances of the incumbent and the position.

Short-Term Incentives . The Enable Midstream Partners, LP Short-Term Incentive Plan applies to our officers and employees. Under our short-term incentive
plan,  we  seek  to  encourage  a  high  level  of  performance  from  our  named  executive  officers  through  the  establishment  of  predetermined  Partnership  goals,  the
attainment of which will require a high degree of competence and diligence on the part of those employees selected to participate, and which will be beneficial to
us and our unitholders . We also seek to encourage a high level of performance from our named executive officers by providing for discretionary awards under our
short-term incentive plan for individual performance.

The  short-term  incentive  plan  is  administered  by  the  Compensation  Committee.  The  Compensation  Committee  approves  the  employees  who  will  be
participants for each plan year, determines the terms and conditions of awards for such participants, including any goals, determines whether goals are achieved,
and whether any awards are paid. The Compensation Committee determines each named executive officer’s short-term incentive target and whether each named
executive  officer  receives  any  discretionary  award.  Determinations  regarding  who  will  be  participants,  the  terms  and  conditions  of  awards,  and  each  named
executive officer’s short-term incentive target are made using market data from the Compensation Committee’s consultant. Payment is made in cash no later than
March 15 of the year following the plan year and may be subject to any restrictions the Compensation Committee may determine. If eligible, a participant may
defer all or a portion of the payment under the deferred compensation plan.

The Compensation Committee may amend, modify, suspend or terminate the short-term incentive plan for the purpose of meeting or addressing any changes
in legal requirements or for any other purpose permitted by law, except that no amendment or alteration that would adversely affect the rights of any participant
under any award previously granted to such participant may be made without the consent of such participant.

Long-Term Incentives . The  Enable  Midstream  Partners,  LP  Long-Term  Incentive  Plan  applies  to  our  officers,  independent  directors  and  employees.  The
purpose of awards to our named executive officers under our long-term incentive plan is to compensate the named executive officers based on the performance of
our common units and their continued employment during the vesting period in order to align their long-term interests with those of our unitholders. Compensating
our  named  executive  officers  for  the  long-term  performance  of  our  common  units  supports  our  pay  for  performance  philosophy.  The  long-term  incentive  plan
provides  for  the  following  types  of  awards:  restricted  units,  phantom  units,  appreciations  rights,  option  rights,  cash  incentive  awards,  performance  units,
distribution equivalent rights, and other awards denominated in, payable in, valued in or otherwise based on or related to common units.

The  long-term  incentive  plan  is  administered  by  the  Compensation  Committee.  Generally,  the  Compensation  Committee  approves  the  participants,
determines  the  award  types  and  amounts,  sets  the  terms  and  conditions  for  awards,  including  performance  goals,  and  determines  whether  awards  are  paid,
including determining whether performance goals have been met. With respect to any grant of equity as long-term incentive awards to our independent directors
and  our  executive  officers  subject  to  reporting  under  Section  16  of  the  Exchange  Act,  the  Compensation  Committee  makes  recommendations  to  the  Board  of
Directors and any such awards will only be effective upon the approval of the Board of Directors. The compensation consultant provides market data to assist the
Compensation Committee in making decisions related to the administration of the long-term incentive plan, including determinations regarding the award types,
amounts, terms and conditions and goals for our named executive officers. The long-term incentive plan limits the number of units that may be delivered pursuant
to vested awards to 13,100,000 common

140

 
Table of Contents

units, subject to proportionate adjustment in the event of unit splits and similar events. Common units cancelled, forfeited, expired or cash settled are available for
delivery pursuant to other awards.

The Board of Directors may terminate or amend the long-term incentive plan at any time with respect to any units for which a grant has not yet been made,
including amending the long-term incentive plan to increase the number of units that may be granted subject to the requirements of the exchange upon which the
common units are listed at that time. However, no change in any outstanding grant may be made that would be adverse to the participant without the consent of the
participant.

Upon  completion  of  the  IPO,  Mr.  Sailor  received  an  award  of  25,000  restricted  units,  which  vested  on  April  16,  2018.  In  order  to  compensate  him  for
forfeiting compensation from his previous employer, Mr. C. Harris received an award of 19,276 phantom units and a performance unit award with an award target
of 26,986 performance units upon his employment with us. For Mr. C. Harris’ phantom unit award, 9,638 units vested on September 6, 2017 and 9,638 units vested
on September 6, 2018. Mr. C. Harris’ performance unit award is subject to the same terms and conditions as the performance unit awards made to our other named
executive officers in 2016, and any performance units earned under this award will vest on September 6, 2019.

Other Compensation and Benefits. Our named executive officers were also eligible to participate in our employee benefit plans and programs, including a

medical benefits plan, a 401(k) plan and a non-qualified deferred compensation plan .

Clawback Policy. In May 2016, our Compensation Committee adopted a Clawback Policy for our executive officers. The policy provides that, in the event of
an  accounting  restatement,  the  Compensation  Committee  may,  within  12  months  after  the  date  the  Partnership  is  required  to  prepare  the  restatement,  require  a
current or former executive officer to forfeit or return incentive-based compensation they would not have received based on the restatement if the Compensation
Committee  determines  that  the  restatement  was  caused,  in  whole  or  in  part,  by  a  willful  act  or  omission  of  the  current  or  former  executive  officer.  The  policy
applies to incentive-based compensation under our short-term incentive plan and long-term incentive plan, and to any other incentive-based compensation, granted
on or after January 1, 2016.

Unit Ownership Guidelines. In August 2015, our Compensation Committee adopted Unit Ownership Guidelines for our independent directors and officers.
We believe that our Unit Ownership Guidelines align the interests of our independent directors and named executive officers with the interests of our unitholders.
The guidelines provide that our Chief Executive Officer should own common units of the Partnership having a market value of five times base salary, the other
named executive officers should own common units of the Partnership having a market value of three times their respective base salaries, and that our independent
directors  should  own  common  units  of  the  Partnership  equal  to  their  respective  annual  base  retainers.  Our  Compensation  Committee  reviews  common  unit
ownership annually, based on the officer’s current base salary or the independent director’s current base retainer, and the average closing price for our common
units for the previous calendar year. The guidelines were established with advice from the Compensation Committee’s consultant.

In addition to units owned directly by our independent directors and officers, units owned indirectly (such as by a spouse or a trust), as well as phantom units
granted under our long-term incentive plan, may be used to satisfy the ownership levels under the guidelines. The guidelines provide that our existing independent
directors and officers should achieve and maintain the minimum ownership levels no later than five years from the adoption of the guidelines. The guidelines also
provide that newly appointed independent directors and newly appointed or promoted officers should achieve and maintain the minimum ownership levels no later
than five years from the date of appointment, hire or promotion.

Hedging  Policy.  As  part  of  the  Insider  Trading  Policy  adopted  by  our  Board  of  Directors,  our  directors,  officers  and  certain  designated  employees  are
prohibited from engaging in forms of hedging or monetization transactions with respect to the Partnership’s securities, such as prepaid variable forward contracts,
equity swaps, collars and exchange funds, that allow an owner of securities to lock in much of the value of her or his holdings, often in exchange for all or part of
the potential for upside appreciation in the security. These types transactions allow insiders to continue to own the securities without the full risks and rewards of
the securities. When that occurs, the owner may not have the same objectives as the Partnership’s other unit holders. Therefore, we have prohibited our directors,
officers and certain designated employees from engaging in these types of transactions.

Base Salary . In February 2018, Mr. Sailor, Mr. Laws, Ms. Farmer and Mr. Schroeder received base salary increases of 6.92%, 18.00%, 4.00%, and 10.00%
respectively. These base salary increases were intended to better align the named executive officers with the market data for their roles. In August 2018, Mr. C.
Harris received a base salary increase of 6.91% in connection with his appointment as Executive Vice President and Chief Operating Officer. Although Mr. C.
Harris’ appointment to Executive Vice President and Chief Operating Officer was not effective until January 1, 2019, his base salary increased in connection with
his appointment and was effective as of August 13, 2018.

Short-Term Incentives . For 2018 , the  target  amount  of the short-term  incentive  award for each  named executive  officer  was a percentage  of actual  base
salary  paid  during  2018  ,  with  a  payout  ranging  from  0%  to  150%  of  the  target,  subject  to  straight-line  interpolation  based  on  the  level  of  achievement  of
performance goals established by the Compensation Committee. The award may be increased or decreased at the discretion of the Compensation Committee based
on the performance of the named executive officer, but the award may not exceed 200% of the named executive officer’s target.

For the 2018 award, the performance goals were based 80% on financial targets and 20% on safety targets. The financial targets consisted of: (i) 30% on
operation  and  maintenance  (O&M)  and  general  and  administrative  (G&A)  expense  targets,  and  (ii)  50%  on  a  distributable  cash  flow  (DCF)  target.  The  safety
targets consisted of (i) 2.5% per quarter, for an overall 10% total recordable incident rate (TRIR) targets, which is derived from the Federal Occupational Safety
and Health Act of 1970 standards for recordable injuries and illnesses (excluding hearing shifts and any recordable injury resulting from a non-preventable vehicle
incident),  and  (ii)  2.5%  per  quarter,  for  an  overall  10%  preventable  vehicle  incident  rate  (PVIR)  targets,  which  is  defined  as  one  in  which  the  driver  failed  to
exercise  every  reasonable  precaution  to  prevent  the  accident.  For  each  performance  goal,  the  Compensation  Committee  established  a  minimum  level  of
performance (at which a 50% payout would be made and below which no payout would be made), a target level of performance (at which a 100% payout would be
made), and a maximum level of performance (at or above which a 150% payout would be made). The level of payout may range from 0% to 150%, subject to
straight-line interpolation based on the actual performance achieved.

For  the  purpose  of  determining  the  level  of  performance  achieved,  the  Compensation  Committee  reserved  the  right  to  adjust  DCF  for  (1)  increases  or
decreases resulting from changes in accounting principles that become effective after December 31, 2017 ; (2) any increases or decreases in DCF attributable to
any new federal or state laws or regulations enacted after December 31, 2017 ; and (3) adjustments to reflect the effect of any acquisitions or divestitures occurring
during the 2018 plan year as permitted under the plan. The Committee also reserved the right to adjust O&M and G&A for (1) increases or decreases in O&M and
G&A attributable to a change in accounting principles effective after December 31, 2017 ; (2) any increases or decreases in O&M and G&A attributable to any
new  federal  or  state  laws  or  regulations  enacted  after  December  31,  2017 ;  (3)  any  increases  or  decreases  in  O&M  and  G&A  attributable  to  gains,  losses,  or
impairments, except those attributable to the write down, abandonment or disposition of any assets never placed in service; (4) any other adjustments in O&M and
G&A  expenses  occurring  during  the  2018 plan  year  approved  by  the  Committee;  and  (5)  adjustments  to  reflect  the  effect  of  any  acquisitions  or  divestitures
occurring during the 2018 plan year as permitted under the plan.

The  DCF  actual  performance  is  the  amount  reported  in  our  2018 financial  statements,  as  adjusted  for  (1)  any  increases  or  decreases  in  O&M  and  G&A
attributable  to  any  new  federal  or  state  laws  or  regulations  enacted  after  December  31,  2017  and  (2)  adjustments  to  reflect  the  effect  of  any  acquisitions  or
divestitures occurring during the 2018 plan year as permitted under the short-term incentive plan. The O&M and G&A actual performance is the amount of O&M
and G&A reported in our 2018 financial statements, as adjusted for: (1) any increases or decreases in O&M and G&A attributable to any new federal or state laws
or  regulations  enacted  after  December  31,  2017 ;  (2)  any  increases  or  decreases  in  O&M  and  G&A  attributable  to  gains,  losses,  or  impairments,  except  those
attributable to the write down, abandonment or disposition of any assets never placed in service; and (3) adjustments to reflect the effect of any acquisitions or
divestitures occurring during the 2018 plan year as permitted under the short-term incentive plan.

Long-Term  Incentives  .  For  2018 ,  each  named  executive  officer  received  a  long-term  incentive  award,  allocated  65%  to  performance  units  and  35%  to
phantom units, in each case with distribution equivalent rights under the long-term incentive plan that will vest on March 1, 2021 , subject to the satisfaction of
vesting criteria. Our named executive officers received the following 2018 performance unit and phantom unit awards:

The  performance  units  awarded  in  2018 have  a  payout  ranging  from  0%  to  200%  of  the  target  based  on  the  level  of  achievement  of  a  performance  goal
established by the Board of Directors over a performance period of January 1, 2018 through December 31, 2020 . Performance units earned will be paid in the
Partnership’s common units, and distribution equivalent rights will be paid in cash at vesting to the extent earned.

For the awards in 2018 , the performance goal was based on the relative total unitholder return (TUR) of our common units over the performance period
compared to a peer group. The peer group consists of the following companies, which were in the Alerian Natural Gas Index at the time of selection, which may be
adjusted by the Compensation Committee, as necessary, from time to time:

If our ranking falls between these percentages, vesting will be determined by straight-line interpolation.

Phantom  units  will  be  paid  in  the  Partnership’s  common  units,  and  distribution  equivalent  rights  will  be  paid  in  cash  during  the  term  of  the  award.  The
vesting of both the performance unit and phantom unit awards is contingent upon the executive’s employment with us on the vesting date. Notwithstanding the
foregoing:  (i)  in  the  event  the  executive’s  employment  is  terminated  due  to  death  or  disability,  we  terminate  the  executive’s  employment  other  than  for  cause
within two years following a change in control, or the executive terminates his employment with us for good reason within two years following a change in control,
the awards will vest; and (ii) in the event the executive’s employment is terminated due to retirement, a portion of the awards will vest upon their retirement based
on the number of days during the three-year vesting period that they are employed by us.

For both the performance  unit and phantom unit awards to our named executive officers: (i) “good reason” means a material  reduction in the executive’s
authority, duties or responsibilities, a decrease in the executive’s base salary by more than 10%, a decrease in the executive’s target award opportunities under our
short-term  incentive  plan  or  long-term  incentive  plan  by  more  than  10%;  or  a  relocation  of  the  executive’s  primary  office  by  more  than  50  miles,  and  (ii)
termination  “for  cause”  means  a  material  act  or  willful  misconduct  that  is materially  detrimental  to the  Partnership,  an act  of  dishonesty  in the  performance  of
duties, habitual unexcused absence(s) from work, willful failure to perform duties in any material respect, gross negligence in the performance of duties resulting
in material damage or injury to the Partnership or any affiliate, any felony conviction, or any other conviction involving dishonesty, fraud or breach of trust.

(1) Amounts in this column reflect the aggregate grant date fair value amount of the Partnership equity-based unit awards granted to each named executive officer. The grant date fair
value amount of performance unit awards is computed in accordance with FASB ASC Topic 718 based on the probable achievement level of the underlying performance conditions
as  of  the  grant  date.  Please  refer  to  the  Grants  of  Plan-Based  Awards  table  for  2018 and  the  accompanying  footnotes.  Assuming  achievement  of  the  performance  goals  at  the
maximum  level,  the  grant  date  fair  value  of  the  performance  units  granted  in  2018 and  included  in  this  column  would  be  $3,318,502  for  Mr.  Sailor,  $1,295,888  for  Mr.  Laws,
$749,524 for Ms. Farmer, $1,057,009 for Mr. C. Harris, and $748,852 for Mr. Schroeder. Assuming achievement of the performance goals at the maximum level, the grant date fair
value of the performance units granted in 2017 and included in this column would be $2,969,584 for Mr. Sailor, $1,020,578 for Mr. Laws, $698,191 for Ms. Farmer, $668,129 for Mr.
C. Harris, and $696,572 for Mr. Schroeder. Assuming achievement of the performance goals at the maximum level, the grant date fair value of the performance units granted in 2016
and included in this column would be $4,324,134 for Mr. Sailor, $1,324,256 for Mr. Laws, $975,938 for Ms. Farmer, $1,498,802 for Mr. C. Harris, and $975,938 for Mr. Schroeder.
The grant date  fair value amount  of phantom  unit  awards is computed  in accordance  with FASB ASC Topic 718. See Note 18 to the financial statements  for a discussion  of the
valuation assumptions used for these awards.

(1) Amounts in columns (c), (d) and (e) of the Grants of Plan-Based Awards Table for 2018 above represent the threshold, target and maximum amounts that would be payable to named
executive  officers  pursuant  to  the  2018 annual  incentive  awards  made  under  the  Enable  Midstream  Partners,  LP  Short-Term  Incentive  Plan.  The  Short-Term  Incentive  Plan  was
designed with a funding trigger that requires threshold performance for the plan to payout. If threshold performance is not met, no payments will be made. For each performance
measure, established thresholds were set (at which 50% payout would be made), a target level of performance (at which a 100% payout would be made) and a maximum level of
performance (at or above which a 150% payout would be made) based on eligible earnings. The award may be increased or decreased at the Compensation Committee’s discretion
based on the performance of the named executive officer, but the award may not exceed 200% of the named executive officer’s target. As discussed in the Compensation Discussion
and  Analysis  above,  the  amount  that  each  executive  officer  will  receive  is  dependent  upon  Partnership  performance  against  a  distributable  cash  flow  target  (50%),  operations  &
maintenance and general & administrative expense (30%) and an aggregate safety target (20%).

(2) Amounts in columns (f), (g) and (h) above represent awards of performance units under Enable Midstream Partners, LP Long-Term Incentive Plan. All payouts of such performance
units  will  be  made  in  units  and  any  accumulated  distribution  equivalent  rights  will  be  paid  in  cash  to  the  extent  earned.  Due  to  their  variable  nature,  accumulated  distribution
equivalent rights are not disclosed in the table above. The conditions of the 2018 award provide that the executive officer will receive from 0% to 200% of the performance units
awarded depending upon the Partnership’s total unitholder return of a group of 16 peer companies over a performance period from January 1, 2018 through December 31, 2020 .
Total unit holder return includes both price appreciation and cash distributions over the performance period. Price appreciation is determined by comparing the average closing price
of units of the Partnership or any company in the peer group for the 20 trading days preceding the performance period and for the last 20 trading days during the performance period.
Cash distributions for the Partnership or any company in the peer group are assumed to have been reinvested in additional units on the date two days prior to the distribution record
date.  At  the  end  of  the  performance  period,  the  terms  of  these  performance  units  provide  for  payout  of  100%  of  the  performance  units  initially  granted  if  the  Partnership’s  total
unitholder  return  is  at  the  50th  percentile  of  the  peer  group,  with  higher  payouts  for  performance  above  the  50th  percentile  up  to  200%  of  the  performance  units  granted  if  total
unitholder return is at or above the 90th percentile of the peer group. The terms of these performance units provide for payouts of less than 100% of the performance units granted if
the Partnership’s total unitholder return is below the 50th percentile of the peer group, with no payout for performance below the 30th percentile.

(3) Amounts in column (i) above represent the number of phantom unit awards granted to each of our named executive officers under the Enable Midstream Partners, LP Long-Term

Incentive Plan.

(4) Amounts reflect the grant date fair value based on a probable value of these awards or target value, of 100% payout. See Note 18 to the financial statements for further information.

The Enable Midstream Partners Deferred Compensation Plan, a nonqualified deferred compensation plan, was adopted in 2014 and, beginning in 2015,
provides a tax-deferred savings plan for certain highly-compensated employees, including our named executive officers, who are selected by the Partnership and
whose participation in the partnership sponsored 401(k) plan is restricted due to compensation and contribution limitations of the Internal Revenue Code. Eligible
employees may voluntarily defer up to 70% of their base salary and 100% of their bonus earned under the Enable Midstream Partners, LP Short Term Incentive
Plan,  and  nonemployee  directors  may  voluntarily  defer  up  to  100%  of  their  cash  director  fees.  In  addition,  the  Partnership  may  make  company  matching  and
annual contributions on behalf of employees whose compensation is above the Internal Revenue Code’s compensation limitation for 401(k) plans. Participating
employees have full discretion over how their contributions to the Deferred Compensation Plan are invested among the offered investment options, and earnings on
amounts  contributed  to  the  Deferred  Compensation  Plan  are  calculated  in  the  same  manner  and  at  the  same  rate  as  earnings  on  actual  investments.  Investment
options under the deferred compensation plan mirror those of the Partnership’s 401(k) plan. Distributions under the deferred compensation plan are payable upon a
separation of service or a “change in control” in either a lump sum or annual installment payments payable over five or ten years at the election of the applicable
participant.  All  amounts  in  a  participant’s  account  are  recorded  in  a  notional  account.  The  Partnership  has  established  a  “rabbi”  trust  to  hold  amounts  that  are
contributed under the deferred compensation plan; however, such amounts contributed to the trust remain assets of the Partnership and subject to the claims of its
creditors. For purposes of the Deferred Compensation Plan, a “change in control” is defined as a change in the

ownership of the employer, a change in effective control of the employer, or a change in the ownership of a substantial portion of the assets of the employer.

Potential Payments Upon Termination or Change-in-Control

Change
of
Control
Plan

On August 1, 2016, the Compensation Committee of the Board adopted the Enable Midstream Partners, LP Change of Control Plan to help recruit and retain
executives. The change of control benefits are “double trigger,” meaning the executive must experience a covered termination during the two years after a change
of control. The plan provides that a covered termination occurs if an executive’s employment is terminated for any reason other than death, disability, cause or
resignation by the executive other than for good reason. The plan also provides that a change of control occurs if: (i) anyone, other than an affiliate of Enable GP,
becomes  the  beneficial  owner  of  more  than  50%  of  the  general  partner  interest  in  the  Partnership;  (ii)  a  plan  of  complete  liquidation  of  Enable  GP  or  the
Partnership is approved; (iii) Enable GP or the Partnership sell or otherwise dispose of all or substantially all of its assets in one or more transactions to anyone
other than an affiliate of Enable GP unless either CenterPoint and its affiliates or OGE Energy and its affiliates own at least 50% of the voting securities of the
acquirer; or (iv) anyone other than Enable GP or an affiliate of Enable GP becomes the general partner of the Partnership.

The plan provides the following change of control benefits for each of our named executive officers:

•

•

•

for  the  President  and  Chief  Executive  Officer,  a  lump-sum  cash  payment  of  2.99  times  his  annual  base  salary  and  short-term  incentive  plan  award
target;

for each Executive Vice President, a lump-sum cash payment of 2.0 times his or her annual base salary and short-term incentive plan award target; and

for  any  other  officer  who  is  not  an  Executive  Vice  President,  a  lump-sum  cash  payment  of  1.5  times  his  or  her  annual  base  salary  and  short-term
incentive plan award target.

For each of our officers, the plan also provides for a lump-sum cash payment in an amount equal to his or her target bonus under the short-term incentive plan
based on eligible earnings through the date of termination and cash payments for certain health and welfare and outplacement benefits. The payment of change of
control  benefits  are  subject  to  the  executive’s  execution,  without  revocation,  of  a  general  waiver  and  release  of  claims.  The  plan  also  contains  standard
confidentiality, non-disparagement and non-solicitation provisions.

Long
Term
Incentives

Awards to our named executive officers under our long-term incentive plan include change of control benefits. The change of control benefits are “double
trigger,” meaning the executive must experience a covered termination during the two years after a change of control for accelerated vesting to occur. Awards to
our named executive officers under Long-Term Incentive Plan will vest in the event: (i) we terminate the executive’s employment other than for cause within two
years following a change in control; or (ii) the executive terminates his or her employment for good reason within two years following a change in control. In the
event  of  a  qualifying  termination  following  a  change  in  control,  performance  unit  awards  will  vest  at  the  greater  of  target  or  actual  performance.  For  more
information regarding the awards to our named executive officers under our long-term incentive plan, see “Executive Compensation Tables” above.

The following table reflects the potential payments that would be made to our named executive officers under our change of control plan and our long-term
incentive plan awards, assuming a termination date of December 31, 2018 and using the closing price of the Partnership’s common units of $ 13.53 as reported on
the NYSE at December 31, 2018 .

Pay Ratio Disclosure

As mandated by the Dodd-Frank Act, Item 402(u) of Regulation S-K requires us to disclose the ratio of the compensation of our Chief Executive Officer to
the total compensation of our median employee. Mr. Sailor, our Chief Executive Officer, had 2018 annual total compensation of $4,500,812. Our median employee
had 2018 annual total compensation of $104,750. As a result, the ratio of Mr. Sailor’s 2018 annual total compensation to our median employee’s 2018 annual total
compensation was approximately 43 to 1.

Mr. Sailor’s 2018 annual total compensation is reported in the Summary Compensation Table provided in this Form 10-K and includes the dollar value of Mr.

Sailor’s base salary and bonus (cash and non-cash). Consistent with the calculation of Mr.

Table of Contents

Sailor’s 2018 annual total compensation, our median employee’s 2018 annual total compensation includes the dollar value of her or his wages plus overtime and
bonus (cash and non-cash).

We chose December  31,  2018  as  the  date  to  identify  our  median  employee,  and  we  identified  our  median  employee  using  a  cash  compensation  measure
consistently applied to all employees, which included each employee’s cash base salary or wages plus overtime and cash bonus paid under our short-term incentive
plan.  This  measure  consistently  excluded  non-cash  compensation,  such  as  non-cash  bonus,  and  also  consistently  excluded  certain  cash  compensation,  such  as
401(k) matching contributions. In identifying our median employee, we included both our direct employees and employees of OGE Energy that are seconded to the
Partnership because OGE is an affiliated third party. The cash compensation for our direct employees was derived from our payroll records and for employees of
OGE that are seconded to the Partnership was derived from OGE Energy’s payroll records, in each case for the period from January 1, 2018 through December 31,
2018 .

Compensation Committee Report

The Compensation Committee reviewed and discussed the Compensation Discussion and Analysis with management. Based upon this review and discussion,
the Compensation Committee recommended that the Compensation Discussion and Analysis be included in the Partnership’s Annual Report on Form 10-K for the
fiscal year ended December 31, 2018 , as filed with the Securities and Exchange Commission.

Transactions with CenterPoint Energy, OGE Energy and ArcLight

Registration
Rights
Related
to
Common
Units

In connection with our IPO, the Partnership entered into a registration rights agreement with affiliates of CenterPoint Energy, OGE Energy and ArcLight.
Affiliates of CenterPoint Energy, OGE Energy and ArcLight each have certain rights to require the Partnership to file and maintain a registration statement with
respect to the resale of their common units. We are not obligated to effect more than (i) three such demand registrations for CenterPoint Energy and OGE Energy
combined, or (ii) two such demand registrations (and no more than one in any twelve-month period) for ArcLight. Affiliates of CenterPoint Energy, OGE Energy
and ArcLight also each have certain rights to request to “piggyback” onto any registration statement filed by the partnership for the sale of common units by the
Partnership  (other  than  pursuant  to  a  demand  registration  discussed  above,  or  other  than  for  an  employee  benefit  plan)  to  resell  their  common  units.  We  have
agreed to pay certain expenses in connection with such demand and piggyback registrations and associated resales of common units, excluding any underwriting
discounts, selling commissions, transfer taxes applicable to the sale of any common units and any fees and disbursements of the selling unitholder’s counsel or any
other advisor of the selling unitholder.

Registration

the resale of the Series A Preferred Units and any other series of preferred units or common units representing limited partnership interests in the Partnership that
are issuable upon conversion of the Series A Preferred Units.

Services
Agreements

In  connection  with  our  formation,  we  entered  into  services  agreements  with  each  of  CenterPoint  Energy  and  OGE  Energy  pursuant  to  which  they  have
provided certain administrative services to us that are generally consistent with the level and type of services they provided to each of their respective businesses
prior to our formation. The initial term of the services agreements ended April 30, 2016, and the services agreements now continue on a year-to-year basis unless
terminated by us at the end of any annual period with at least 90 days’ notice. We may also terminate each services agreement, or the provision of any services
thereunder, with the approval of our Board of Directors with at least 180 days’ notice; provided, however, that the services agreement with OGE Energy, and the
provision of payroll and benefit administration services thereunder, may not be terminated until the transitional seconding agreement between the Partnership and
OGE Energy is terminated.

Originally,  the  services  provided  by  CenterPoint  Energy  and  OGE  Energy  included  accounting,  finance,  legal,  risk  management,  information  technology,
human resources, and other administrative services. Over time, we have reduced our reliance on administrative services provided by CenterPoint Energy and OGE
Energy and, as a result, exercised our option to terminate most of the services provided under the services agreements. As of December 31, 2018 , the services
provided  by  CenterPoint  Energy  primarily  consisted  of  the  provision  of  certain  office  space  and  data  center  space,  and  the  services  provided  by  OGE  Energy
primarily consisted of payroll and benefit administration services related to the transitional seconding agreement between the Partnership and OGE Energy.

We are required to reimburse CenterPoint Energy and OGE Energy for their direct expenses or, where the direct expenses cannot reasonably be determined,
an allocated cost as set forth in the agreements. Unless otherwise approved by the Board of Directors, our reimbursement obligations are capped at amounts set
forth in our annual budget. Under the services agreement, we reimbursed $1 million and $1 million to CenterPoint Energy and OGE Energy, respectively, for the
year ended December 31,

2018 .

Employee
Secondment

In connection with our formation, we entered into an employee transition agreement with CenterPoint Energy and OGE Energy and a transitional seconding
agreement  with  each  of  CenterPoint  Energy  and  OGE  Energy  in  May  2013  ,  pursuant  to  which  they  agreed  to  second  certain  of  their  employees  to  us.  The
Partnership transitioned seconded employees from CenterPoint Energy and OGE Energy to the Partnership effective January 1, 2015, except for certain employees
who are participants under OGE Energy’s defined benefit and retiree medical plans, who remain seconded to the Partnership, subject to certain termination rights
of the Partnership and OGE Energy. Each of the seconded employees works full time for us and our subsidiaries but remains employed by OGE Energy . We are
required to reimburse OGE Energy for certain employment-related costs, including base salary and short and long-term compensation costs and OGE Energy’s
share of costs related to taxes, insurance and other benefit matters under the agreements. 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 a cap of $5 million in 2018 and thereafter, unless and
until secondment is terminated.

Shreveport
Lease

The Partnership leases office and data center space from an affiliate of CenterPoint Energy in Shreveport, Louisiana. The term of the lease was effective on
October 1, 2016 and extends through December 31, 2019. The Partnership incurred approximately $1 million in rent and maintenance expenses under the lease
during the year ended December 31, 2018 .

Omnibus
Agreement

In connection with our formation, we entered into an omnibus agreement that primarily addresses competition restrictions on CenterPoint Energy and OGE
Energy. The omnibus agreement provides that both CenterPoint Energy and OGE Energy are prohibited from, directly or indirectly, owning, operating, acquiring
or investing in any business engaged in midstream operations located within the United States, other than through us. This requirement applies to both CenterPoint
Energy and OGE Energy for so long as either CenterPoint Energy or OGE Energy holds any interest in our general partner or at least 20% of our common units.
“Midstream  operations”  generally  means,  subject  to  certain  exceptions,  the  gathering,  compression,  treatment,  processing,  blending,  transportation,  storage,
isomerization  and  fractionation  of  crude  oil  and  natural  gas,  its  associated  production  water  and  enhanced  recovery  materials  such  as  carbon  dioxide,  and  its
respective  constituents  and the following products:  methane,  NGLs (Y-grade,  ethane,  propane,  normal  butane,  isobutane and natural  gasoline),  condensate,  and
refined products and distillates (gasoline, refined product blendstocks, olefins, naphtha, aviation fuels, diesel, heating oil, kerosene, jet fuels, fuel oil, residual fuel
oil, heavy oil, bunker fuel, cokes, and asphalts).

The prohibition on CenterPoint Energy and OGE Energy either directly or indirectly, owning, operating, acquiring or investing in any business engaged in
midstream  operations,  other  than  through  us,  is  subject  to  the  following  exceptions.  CenterPoint  Energy  or  OGE  Energy  may  acquire  a  business  engaged  in
midstream operations if:

• Such party intends to cease using the midstream operations assets of the business within 12 months of the acquisition of such business; or

•

Such party acquires a business with midstream operations having a value in excess of $50 million (or $100 million in the aggregate with any of such
party’s other midstream operations assets), and it offers to us the opportunity to acquire the midstream operations assets of such business.

Tax
Sharing
Agreement

In connection with our formation, we entered into a tax sharing agreement with CenterPoint Energy, OGE Energy and Enable GP on May 1, 2013 pursuant
to  which  we  agreed  to  reimburse  them  for  state  income  and  franchise  taxes  attributable  to  our  activities  (including  the  activities  of  our  direct  and  indirect
subsidiaries) that is reported on their state income or franchise tax returns filed on a combined or unitary basis. Our general partner is responsible for determining
whether CenterPoint Energy and OGE Energy is required to include our activities on a consolidated, combined or unitary tax return. Reimbursements under the
agreement equal the amount of tax that we and our subsidiaries would be required to pay if we were to file a consolidated, combined or unitary tax return separate
from CenterPoint Energy or OGE Energy . We are required to pay the reimbursement within 90 days of CenterPoint Energy or OGE Energy filing the combined or
unitary tax return on which our activity is included, subject to certain prepayment provisions.

Reimbursement of Expenses of Our General Partner

Our  general  partner  does  not  receive  any  management  fee  or  other  compensation  for  its  management  of  our  partnership;  however,  our  general  partner  is
reimbursed by us for (i) all salary, bonus, incentive compensation and other amounts paid to any employee of the general partner that manages our business and (ii)
all overhead and general and administrative expenses allocable to us that are incurred by the general partner. Our Partnership Agreement provides that our general
partner determines the expenses that are allocable to us.

Transportation, Storage and Commodity Transactions with Affiliates of CenterPoint Energy and OGE Energy

Transportation
and
Storage
Agreements
with
CenterPoint
Energy

EGT provides natural gas transportation and storage services to CenterPoint Energy's LDCs in Arkansas, Louisiana, Oklahoma and Notheast Texas under a
combination  of  contracts  that  include  the  following  types  of  services:  firm  transportation,  firm  transportation  with  seasonal  demand,  firm  storage,  no-notice
transportation  with  storage  and  maximum  rate  firm  transportation.  These  contracts  are  in  effect  through  March  31,  2021.  CenterPoint’s  LDCs  have  initiated
proceedings before the state utility commissions in Arkansas and Oklahoma to consider whether contracts extending transportation and storage services with EGT
would  be  more  favorable  than  the  expected  results  of  competitive  bidding  for  the  same  services.  If  the  proposed  contracts  are  approved,  then  the  term  for  the
transportation  and  storage  services  provided  to  CenterPoint  Energy’s  LDCs  in  Arkansas,  Louisiana,  Oklahoma  and  Northeast  Texas  will  be  extended  beyond
March 31, 2021, pursuant to the terms of the approved contracts. For the year ended December 31, 2018 , we recorded revenues from CenterPoint Energy's LDCs
of $111 million for natural gas transportation and storage services.

We repair and maintain our transportation systems as necessary to continue the safe and reliable operations of our pipelines. From time to time, the repair and
maintenance  of our pipelines  impacts  the  delivery  points  where our customers  receive  natural  gas from  our transportation  systems.  On occasion,  those impacts
require our customers to modify their receipt facilities in order to continue to receive natural gas from our pipelines. Under those circumstances, we may agree to
reimburse the costs that our customers incur to make the required modifications. For the year ended December 31, 2018 , we reimbursed CenterPoint Energy’s
LDCs $1 million in connection with receipt facility modifications that were necessitated by the repair and maintenance of our pipelines and in connection with a
reimbursement associated with an unplanned pipeline outage.

Transportation
and
Storage
Agreements
with
OGE
Energy

EOIT  provides  no-notice  load-following  transportation  and  storage  services  to  OGE  Energy.  On  March  17,  2014,  EOIT  entered  into  a  transportation
agreement with OGE Energy for four of its generating facilities, with a primary term of May 1, 2014 through April 30, 2019. On October 24, 2018, EOIT entered
into a no-notice load-following transportation agreement with OGE Energy, with a primary term of April 1, 2019 through May 1, 2024. Following the primary
term, the agreement will remain in effect from year to year thereafter unless and until either party provides notice of termination to the other party at least 180 days
prior  to  the  commencement  of  the  succeeding  annual  period.  On  December  6,  2016,  EOIT  entered  into  an  additional  firm  transportation  agreement  with  OGE
Energy, for one of its generating facilities with a primary term that began on December 1, 2018 through December 1, 2038. For the year ended December 31, 2018
, we recorded revenues from OGE Energy of $37 million for natural gas transportation and storage services.

From  time  to  time,  we  sell  natural  gas  volumes  to  affiliates  of  CenterPoint  Energy  and  OGE  Energy  or  purchase  natural  gas  volumes  from  affiliates  of
CenterPoint Energy through a combination of forward, monthly and daily transactions. We enter into these physical natural gas transactions in the normal course of
business based upon relevant market prices. In the year ended December 31, 2018 , we recorded revenues of $11 million from gas sales to CenterPoint Energy and
revenues of $4 million from gas sales to OGE Energy. In addition, we recorded $3 million and $23 million for costs of natural gas purchases from CenterPoint
Energy and OGE Energy in the year ended December 31, 2018 respectively.

Review, Approval or Ratification of Transactions with Related Persons

The Board of Directors has adopted a related party transactions policy providing that the Board of Directors or its authorized committee will review on at
least a quarterly basis all related person transactions that are required to be disclosed under SEC rules and, when appropriate, initially authorize or ratify all such
transactions.  In the event that the Board of Directors  or its authorized  committee  considers  ratification  of a related  person transaction  and determines  not to so
ratify, the related party transactions policy will provide that our management will make all reasonable efforts to cancel or annul the transaction.

The  related  party  transactions  policy  provides  that,  in  determining  whether  or  not  to  recommend  the  initial  approval  or  ratification  of  a  related  person
transaction, the Board of Directors or its authorized committee should consider all of the relevant facts and circumstances available, including (if applicable) but
not limited to: (1) whether there is an appropriate business justification for the transaction; (2) the benefits that accrue to us as a result of the transaction; (3) the
terms available to unrelated third parties entering into similar transactions; (4) the impact of the transaction on a director’s independence (in the event the related
person  is  a  director,  an  immediate  family  member  of  a  director  or  an  entity  in  which  a  director  or  an  immediate  family  member  of  a  director  is  a  partner,
shareholder, member or executive officer); (5) the availability of other sources for comparable products or services; (6) whether it is a single transaction or a series
of ongoing, related transactions; and (7) whether entering into the transaction would be consistent with the code of business conduct and ethics.

Pursuant to our related party transactions policy, the Board of Directors has authorized natural gas transportation and storage agreements with CenterPoint
Energy and OGE Energy and their respective affiliates as well as natural gas sale and purchase transactions with CenterPoint Energy and OGE Energy and their
respective affiliates. With respect to natural gas transportation and storage agreements, the Board of Directors has determined that because the rates, charges, and
other  terms  for  transportation  and  storage  services  are  subject  to  regulation,  the  terms  available  to  CenterPoint  Energy  and  OGE  Energy  are  on  terms  no  less
favorable to us than those generally provided to or available from unrelated third parties entering into similar transactions. With respect to natural gas sale and
purchase transactions, the Board of Directors has determined that because there is a robust, liquid market for natural gas, with transparent price determination by
market conditions with reference to indexes, the terms available to CenterPoint Energy and OGE Energy are on terms no less favorable to us than those generally
provided to or available from unrelated third parties entering into similar transactions.

Many of the other related party transactions  policy described above were entered  into prior to the closing of our IPO and, as a result, were not reviewed
under  our  related  party  transactions  policy.  These  transactions  were  entered  into  by  and  among  affiliated  entities  and,  consequently,  may  not  reflect  terms  that
would  result  from  arm’s-length  negotiations.  Because  some  of  these  agreements  relate  to  our  formation  and,  by  their  nature,  would  not  occur  in  a  third-party
situation,  it  is  not  possible  to  determine  what  the  differences  would  be  in  the  terms  of  these  transactions  when  compared  to  the  terms  of  transactions  with  an
unaffiliated third party. We believe the terms of these agreements to be comparable to the terms of agreements used in similarly structured transactions.

Director Independence

Because we are a publicly traded partnership, the NYSE does not require our Board of Directors to have a majority of independent directors. For a discussion

of the independence of our Board of Directors, please see “Item 10. Directors, Executive Officers and Corporate Governance—Management of the Partnership.”

Item 14. Principal Accountant Fees and Services

We  have  engaged  Deloitte  &  Touche  LLP  as  our  independent  registered  public  accounting  firm.  The  following  table  summarizes  the  fees  we  have  paid

Form 10-Qs.

Audit-related  fees  for  the  years  ended  December  31, 2018  and 2017 ,  include  fees  associated  with  comfort  letters  issued  in  connection  with  registration

statements filed by the Partnership or its affiliates.

Tax fees represent amounts we were billed in each of the years presented for professional services rendered in connection with tax compliance, tax advice
and tax planning. This category primarily includes services relating to the preparation of unitholder annual K-1 statements and the preparation of U.S. federal and
state income tax returns for Enable Midstream Partners, LP. These services primarily relate to the two tax years ended December 31, 2018 and 2017 .

Audit
Committee
Approval
of
Audit
and
Non-Audit
Services

The Audit Committee of the Enable GP Board of Directors is responsible for pre-approving audit and non-audit services performed by Deloitte & Touche
LLP . In addition to its approval of the audit engagement, the Audit Committee takes action at least annually to authorize the independent auditor’s performance of
several specific types of services within the categories of audit-related services and tax services. Audit-related services include assurance and related services that
are  reasonably  related  to  the  performance  of  the  audit  or  review  of  the  financial  statements  or  that  are  traditionally  performed  by  the  independent  auditor.  Tax
services include compliance-related services such as services involving tax filings, as well as consulting services such as tax planning, transaction analysis and
opinions. Additional services are subject to preapproval if they are outside the specific types of services included in the periodic approvals or if they are in excess
of the fee limitations in the periodic approvals. The Audit Committee may delegate preapproval authority to one or more members, provided that the delegated
decision must be presented to the Audit Committee at its next scheduled meeting.

The Audit Committee has approved the appointment of Deloitte & Touche LLP as our independent registered public accounting firm to conduct the audit of

the Partnership’s consolidated financial statements for the year ended December 31, 2018 .

LONG TERM INCENTIVE PLAN

ANNUAL PERFORMANCE UNIT AWARD AGREEMENT FOR OFFICERS

Enable  Midstream  Partners,  LP  (the  “  Partnership
 ”)  is  pleased  to  inform  you,  [Participant  Name]  ,  that,  subject  to
