Item 1. Business

Unless  the  context  otherwise  requires,  references  in  this  Annual  Report  on  Form  10-K  to  “we,”  “our,”  “us”  or  like  terms  refer  to  the  business  of

Boardwalk Pipeline Partners, LP and its consolidated subsidiaries.

Introduction

We are a Delaware limited partnership formed in 2005. Our business, which is conducted by our primary subsidiary, Boardwalk Pipelines, LP (Boardwalk
Pipelines)  and  its  operating  subsidiaries  (together,  the  operating  subsidiaries),  consists  of  integrated  natural  gas  and  natural  gas  liquids  and  other  hydrocarbons
(herein referred to together as NGLs) pipeline and storage systems. All of our operations are conducted by the operating subsidiaries. As of December 31, 2020,
Boardwalk Pipelines Holding Corp., a wholly-owned subsidiary of Loews Corporation (Loews), owned directly or indirectly, 100% of our capital.
Our Business

We  operate  in  the  midstream  portion  of  the  natural  gas  and  NGLs  industry,  providing  transportation  and  storage  for  those  commodities.  We  own
approximately 14,095 miles of natural gas and NGLs pipelines and underground storage caverns having aggregate capacity of approximately 213.0 billion cubic
feet (Bcf) of working natural gas and 32.1 million barrels (MMBbls) of NGLs. Our natural gas pipeline systems are located in the Gulf Coast region, Oklahoma,
Arkansas and the Midwestern states of Tennessee, Kentucky, Illinois, Indiana and Ohio, and our NGLs pipelines and storage facilities are located in Louisiana and
Texas.

We serve a broad mix of customers, including local distribution companies (LDCs), electric power generators, exporters of liquefied natural gas (LNG),
industrial  users,  producers  and  marketers  of  natural  gas,  and  interstate  and  intrastate  pipelines.  We  provide  a  significant  portion  of  our  natural  gas  pipeline
transportation  and storage services through firm contracts under which our customers pay monthly capacity reservation fees, which are fixed fees based on the
quantity  of  capacity  reserved,  regardless  of  use.  Other  fees  are  based  on  actual  utilization  of  the  capacity  under  firm  contracts  and  contracts  for  interruptible
services.  Contracts  for  our  NGLs  services  are  generally  fee-based  or  based  on  minimum  volume  requirements,  while  others  are  dependent  on  actual  volumes
transported  or  stored.  For  the  year  ended  December  31,  2020,  approximately  90%  of  our  revenues  were  derived  from  capacity  reservation  fees  under  firm
contracts, approximately 6% of our revenues were derived from fees based on utilization under firm contracts and approximately 4% of our revenues were derived
from interruptible transportation, interruptible storage, parking and lending (PAL) and other services.

The maximum rates we can charge for most of our natural gas transportation services, as well as the general terms and conditions of those services, are
established  by,  and  subject  to  review  and  revision  by,  the  Federal  Energy  Regulatory  Commission  (FERC).  These  rates  are  based  upon  certain  assumptions  to
allow us the opportunity to recover the cost of providing these services and earn a reasonable return on equity. However, it is possible that we may not recover all
of our costs or earn a return. We are authorized to charge market-based rates for the majority of our natural gas storage capacity pursuant to authority granted by
the  FERC.  The  Surface  Transportation  Board  (STB)  regulates  the  rates  we  charge  for  interstate  service  on  ethylene  pipelines.  The  Louisiana  Public  Service
Commission  (LPSC)  regulates  the  rates  we  charge  for  intrastate  service  within  the  state  of  Louisiana  on  our  petrochemical  and  NGLs  pipelines.  The  STB  and
LPSC require that our transportation rates are reasonable and that our practices cannot unreasonably discriminate among our shippers.

Our Pipeline and Storage Systems

We  own  and  operate  approximately  13,650  miles  of  interconnected  natural  gas  pipelines,  directly  serving  customers  in  thirteen  states  and  indirectly
serving customers throughout the northeastern and southeastern United States (U.S.) through numerous interconnections with unaffiliated pipelines. We also own
and operate approximately 445 miles of NGLs pipelines in Louisiana and Texas. In 2020, our pipeline systems transported approximately 3.2 trillion cubic feet
(Tcf) of natural gas and approximately 80.6 MMBbls of NGLs. Average daily throughput on our natural gas pipeline systems during 2020 was approximately 8.6
Bcf.  Our  natural  gas  storage  facilities  are  comprised  of  fourteen  underground  storage  fields  located  in  four  states  with  aggregate  working  gas  capacity  of
approximately  213.0  Bcf  and  our  NGLs  storage  facilities  consist  of  eleven  salt-dome  caverns  located  in  Louisiana  with  an  aggregate  storage  capacity  of
approximately 32.1 MMBbls. We also own seven salt-dome caverns and related brine infrastructure for use in providing brine supply services and to support the
NGLs storage operations.

The  principal  sources  of  supply  for  our  natural  gas  pipeline  systems  are  regional  supply  hubs  and  market  centers  located  in  the  Gulf  Coast  and  Mid-
Continent regions, including offshore Louisiana, the Perryville, Louisiana, area, the Henry Hub in Louisiana and the Carthage, Texas, area. Our pipelines in the
Carthage, Texas, area provide access to natural gas supplies from the Barnett and Haynesville Shales and other natural gas producing regions in eastern Texas and
northern Louisiana. The Henry Hub serves as the designated delivery point for natural gas futures contracts traded on the New York Mercantile Exchange. Our
pipeline systems also have access to supply basins such as the Woodford and Scoop/Stack Shales in Oklahoma, the Fayetteville Shale in Arkansas, the Eagle Ford
Shale in southern Texas and wellhead supplies in northern and southern Louisiana and Mississippi, and we also receive gas in the Lebanon, Ohio, area from the
Marcellus and Utica Shales located in the northeastern U.S. Our NGLs pipeline systems access the Gulf Coast petrochemical industry through our operations at our
Choctaw Hub in the Mississippi River corridor area of Louisiana and the Sulphur Hub in the Lake Charles, Louisiana, area. We also access ethylene supplies at
Port Neches, Texas, which we deliver to petrochemical-industry customers in Louisiana.

The following is a summary of each of our principal operating subsidiaries:

Gulf  South  Pipeline  Company,  LLC  (Gulf  South):  Effective  January  1,  2020,  Gulf  South  converted  from  a  limited  partnership  to  a  limited  liability
company. Immediately subsequent to the conversion, our Gulf Crossing Pipeline Company LLC, operating subsidiary was merged into Gulf South. Our merged
Gulf South pipeline system is located along the Gulf Coast in the states of Oklahoma, Texas, Louisiana, Mississippi, Alabama and Florida. The on-system markets
directly served by the Gulf South system are generally located in eastern Texas, Louisiana, southern Mississippi, southern Alabama and the Florida Panhandle.
Gulf South also services the Perryville Exchange. These markets include LNG export markets in the Freeport, Texas, area, power plants, LDCs and municipalities
located across the system, including New Orleans, Louisiana; Jackson, Mississippi; Mobile, Alabama; Houston, Texas; and Pensacola, Florida, and other end-users
located across the system, including the Baton Rouge to New Orleans industrial corridor and Lake Charles, Louisiana. Gulf South also has indirect access to off-
system  markets  through  numerous  interconnections  with  unaffiliated  interstate  and  intrastate  pipelines  and  storage  facilities.  These  pipeline  interconnections
provide access to markets throughout the northeastern, midwestern and southeastern U.S.

Gulf  South  has  ten  natural  gas  storage  facilities.  The  two  natural  gas  storage  facilities  located  in  Bistineau,  Louisiana,  and  Jackson,  Mississippi,  have
approximately 91.5 Bcf of working gas storage capacity from which Gulf South offers firm and interruptible storage service, including no-notice service (NNS),
and are used to support pipeline operations. Gulf South also owns and operates eight high deliverability salt-dome natural gas storage caverns in Forrest County,
Mississippi, having approximately 46.0 Bcf of total storage capacity, of which approximately 29.6 Bcf is working gas capacity, and owns undeveloped land which
is suitable for up to five additional storage caverns. 

Texas  Gas  Transmission,  LLC  (Texas  Gas):  Our  Texas  Gas  pipeline  system  is  a  bi-directional  pipeline  located  in  Louisiana,  East  Texas,  Arkansas,
Mississippi, Tennessee, Kentucky, Indiana and Ohio, with smaller diameter lines extending into Illinois. Texas Gas directly serves LDCs, municipalities and power
generators in its market area, which encompasses eight states in the South and Midwest and includes the Memphis, Tennessee; Louisville, Kentucky; Cincinnati
and  Dayton,  Ohio;  and  Evansville  and  Indianapolis,  Indiana,  metropolitan  areas.  Texas  Gas  also  has  indirect  market  access  to,  and  receives  supply  from,  the
Northeast through interconnections with unaffiliated pipelines. A large portion of the gas delivered by the Texas Gas system is used for heating during the winter
months, but Texas Gas also supplies gas for cooling needs during the summer months.

Texas  Gas  owns  nine  natural  gas  storage  fields,  of  which  it  owns  the  majority  of  the  working  and  base  gas.  Texas  Gas  uses  this  gas  to  meet  the
operational requirements of its transportation and storage customers and the requirements of its NNS customers. Texas Gas also uses its storage capacity to offer
firm and interruptible storage services.

Boardwalk Louisiana Midstream, LLC and Boardwalk Petrochemical Pipeline, LLC (collectively, Louisiana Midstream): Louisiana Midstream provides
transportation and storage services for natural gas, NGLs and ethylene, fractionation services for NGLs and brine supply services for producers and consumers of
petrochemicals through two hubs in southern Louisiana - the Choctaw Hub in the Mississippi River corridor area and the Sulphur Hub in the Lake Charles area.
These  assets  provide  approximately  48.8  MMBbls  of  salt-dome  storage  capacity,  including  approximately  7.6  Bcf  of  working  natural  gas  storage  capacity;
significant brine supply infrastructure; and approximately 285 miles of pipeline assets, including an extensive ethylene distribution system. Louisiana Midstream
also owns and operates the Evangeline Pipeline, an approximately 175-mile interstate ethylene pipeline that is capable of transporting approximately 4.2 billion
pounds of ethylene per year between Port Neches, Texas, and Baton Rouge, Louisiana, with interconnections with the ethylene distribution system and storage
facilities at the Sulphur and Choctaw Hubs. Throughput for Louisiana Midstream was 80.6 MMBbls for the year ended December 31, 2020.

Boardwalk  Texas  Intrastate,  LLC  (Boardwalk  Texas  Intrastate):  Boardwalk  Texas  Intrastate  provides  intrastate  natural  gas  transportation  services  on
pipelines located in South Texas extending on the west side from Bee County, near the Eagle Ford Shale, and Agua Dulce to the Corpus Christi area and to an
interconnect with Gulf South in Jackson County, Texas. Boardwalk Texas Intrastate is situated to provide access to industrial and power generation markets in the
Corpus Christi area as well as LNG export markets and third-party pipelines for exports to Mexico.

In  2020,  we  placed  into  service  approximately  $335.0  million  of  growth  projects  which  represents  approximately  1.5  Bcf/d  of  firm  natural  gas
transportation capacity and additional NGL infrastructure. Additionally, we expanded our natural gas storage capacity at our Forrest County, Mississippi, storage
facilities.  Collectively,  these  projects  were  completed  on-time  and  within  budget.  We  expect  to  spend  approximately  $380.0  million  on  our  growth  projects
currently under construction through 2024. Those projects are expected to serve increased natural gas demand from a power generation plant and liquids demand
from petrochemical facilities. All of our growth projects are secured by long-term firm contracts.

financing.

Nature of Contracts

We  contract  with  our  customers  to  provide  transportation  and  storage  services  on  both  a  firm  and  interruptible  basis.  We  also  provide  bundled  firm
transportation  and  storage  services,  such  as  NNS,  interruptible  PAL  services  for  our  customers,  brine  supply  services  for  certain  petrochemical  customers  and
fractionation services.

Transportation Services: We offer transportation services on both a firm and interruptible basis. Our customers choose, based upon their particular needs,
the applicable mix of services depending upon availability of pipeline capacity, the price of services and the volume and timing of customer requirements. Our firm
transportation customers reserve a specific amount of pipeline capacity at specified receipt and delivery points on our system. The transaction price for firm service
contracts is comprised of a fixed fee based on the quantity of capacity reserved, regardless of use (capacity reservation fee), plus variable fees in the form of a
usage fee paid on the volume of commodity actually transported or injected and withdrawn from storage. Capacity reservation revenues derived from a firm service
contract  are  generally  consistent  during  the  contract  term,  but  can  be  higher  in  winter  periods  than  the  rest  of  the  year,  especially  for  NNS  agreements.  Firm
transportation contracts can range from one to twenty years, although we may enter into shorter- or longer-term contracts. In providing interruptible services to
customers, we agree to transport natural gas or NGLs for a customer when capacity is available. Interruptible service customers pay a commodity charge only for
the volume of gas actually transported, plus a fuel charge. Interruptible transportation agreements have terms ranging from day-to-day to multiple years, with rates
that change on a daily, monthly or seasonal basis. Our NGLs transportation services are generally fee-based or based on minimum volume requirements.

Storage  and  Parking  and  Lending  Services: We  offer  natural  gas  and  NGLs  storage  services  on  both  a  firm  and  interruptible  basis.  Firm  storage
customers  reserve  a  specific  amount  of  storage  capacity,  including  injection  and  withdrawal  rights,  while  interruptible  customers  receive  storage  capacity  and
injection  and  withdrawal  rights  when  available.  Similar  to  firm  transportation  customers,  firm  storage  customers  generally  pay  fees  based  on  the  quantity  of
capacity reserved plus an injection and withdrawal fee. Firm storage contracts typically range in term from one to ten years. Interruptible storage customers pay for
the volume of gas actually stored plus injection and withdrawal fees. Generally, interruptible storage

5

 
agreements are for monthly terms. We are able to charge market-based rates for the majority of our natural gas storage capacity pursuant to authority granted by
the FERC. Our NGLs storage rates are market-based, and the contracts for NGLs services are typically fixed-price arrangements with escalation clauses. PAL is an
interruptible  service  offered  to  customers  providing  them  the  ability  to  park  (inject)  or  borrow  (withdraw)  natural  gas  into  or  out  of  our  pipeline  systems  at  a
specific location for a specific period of time. Customers pay for PAL services in advance or on a monthly basis depending on the terms of the agreement.

No-Notice Services: NNS  consist  of  a  combination  of  firm  natural  gas  transportation  and  storage  services  that  allow  customers  to  inject  or  withdraw
natural gas from storage with little or no notice. Customers pay a reservation charge based upon the capacity reserved plus a commodity and a fuel charge based on
the volume of gas actually transported. In accordance with its tariff, Texas Gas loans stored gas to certain of its no-notice customers who are obligated to repay the
gas in-kind.

Customers and Markets Served

We  contract  directly  with  end-use  customers,  including  LDCs,  electric  power  generators,  exporters  of  LNG  and  industrial  users,  with  producers  and
marketers of natural gas, and with interstate and intrastate pipelines, who, in turn, provide transportation and storage services for end-users. Based on our 2020
transportation, storage and PAL revenues, net of fuel, our customer mix was as follows: marketers (22%), power generators (22%), natural gas producers (19%),
LDCs (16%), industrial end-users (12%) and exporters of LNG (9%). Based upon our 2020 transportation, storage and PAL revenues, net of fuel, our deliveries
were as follows: pipeline interconnects (32%), LDCs (19%), power generators (16%), industrial end-users (14%), storage activities (9%), exporters of LNG (9%)
and others (1%). One customer comprised approximately 10% of our operating revenues in 2020.

Marketers: Natural gas marketing companies utilize our services to provide services to our other customer groups as well as to customer groups in off-
system  markets.  The  services  may  include  combined  gas  transportation  and  storage  services  to  support  the  needs  of  the  other  customer  groups.  Some  of  the
marketers are sponsored by LDCs or producers.

Power Generators: Our natural gas pipelines are directly connected to 45 natural-gas-fired power generation facilities in nine states. The demand of the
power generating customers generally peaks during the summer cooling season which is counter to the winter season peak demands of the LDCs, although demand
from power generators remains strong in the winter months as well, due to the overall increase in the use of natural gas over other sources, such as coal, to generate
electricity. Our power generating customers can use a combination of NNS, firm and interruptible transportation services.    

Natural Gas Producers: Producers of natural gas use our services to transport gas supplies from producing areas, including shale natural gas production
areas, to supply pools and to other customers on and off of our systems. Producers contract with us for storage services to store excess production and to optimize
the ultimate sales prices for their gas.

Local Distribution Companies: Most of our LDC customers use firm natural  gas transportation  services, including NNS. We serve approximately  175

LDCs at more than 300 delivery locations across our pipeline systems. The demand of these customers peaks during the winter heating season.

Industrial  End-Users: We  provide  approximately  186  industrial  facilities  with  a  combination  of  firm  and  interruptible  natural  gas  and  NGLs
transportation and storage services. Our pipeline systems are directly connected to industrial facilities in the Baton Rouge to New Orleans industrial corridor; Lake
Charles, Louisiana; Mobile, Alabama; and Pensacola, Florida. We can also access the Houston Ship Channel through third-party natural gas pipelines.

Exporters  of  LNG:  LNG  exporters  use  our  firm  transportation  services  to  reach  LNG  liquefaction  and  export  facilities.  We  provide  1.4  Bcf/d  of  firm

natural gas transportation service directly to the Freeport LNG liquefaction and export facility in Freeport, Texas.

Our  delivery  market  has  diversified  over  time,  with  increased  deliveries  to  our  end-use  customers,  whereas  historically,  our  delivery  markets  were
primarily  to  other  pipelines  who  then  delivered  to  the  end-use  customers.  As  of  December  31,  2020,  we  had  approximately  $9.5  billion  of  projected  operating
revenues  under  committed  firm  transportation  agreements,  of  which  our  deliveries  are  expected  to  be  as  follows:  power  generators  (30%),  exporters  of  LNG
(22%), pipeline interconnects (21%) industrial end-users (13%), LDCs (8%), storage activities (5%) and others (1%).

Government Regulation

Federal Energy Regulatory Commission: The FERC regulates our interstate natural gas transmission operating subsidiaries under the Natural Gas Act of
1938 (NGA) and the Natural Gas Policy Act of 1978 (NGPA). The FERC regulates, among other things, the rates and charges for the transportation and storage of
natural gas in interstate commerce and the construction, extension, enlargement or abandonment of facilities under its jurisdiction. Where required, our interstate
natural gas pipeline subsidiaries hold certificates of public convenience and necessity issued by the FERC covering certain of their facilities, activities and services.
The FERC also prescribes accounting treatment for our interstate natural gas pipeline subsidiaries which is separately reported pursuant to forms filed with the
FERC.  The  regulatory  books  and  records  and  other  activities  of  our  subsidiaries  that  operate  under  the  FERC's jurisdiction  may  be  periodically  audited  by  the
FERC.

The maximum rates that our FERC-regulated operating subsidiaries may charge for all aspects of the natural gas transportation services they provide are
established through the FERC's cost-based rate-making process. Key determinants in the FERC's cost-based rate-making process are the costs of providing service,
the volumes of gas being transported, the rate design, the allocation of costs between services, the capital structure and the rate of return a pipeline is permitted to
earn. The maximum rates that may be charged by us for storage services on Texas Gas, except for services associated with a portion of the working gas capacity on
that  system,  are  also  established  through  the  FERC's  cost-based  rate-making  process.  The  FERC  has  authorized  us  to  charge  market-based  rates  for  firm  and
interruptible storage services for the majority of our other natural gas storage facilities. None of our FERC-regulated entities currently have an obligation to file a
new rate case, and Gulf South is prohibited from filing a rate case until May 1, 2023, subject to certain exceptions.

Boardwalk Texas Intrastate transports natural gas in intrastate commerce under the rules and regulations established by the Texas Railroad Commission
and in interstate commerce that is subject to FERC jurisdiction under Section 311 of the NGPA. The maximum rates for services are established under Section 311
of the NGPA and are generally subject to review every five years by the FERC.

Surface Transportation Board and Louisiana Public Service Commission: The STB regulates the rates we charge for interstate service on our ethylene
pipelines. The LPSC regulates the rates we charge for intrastate service within the state of Louisiana on our petrochemical and NGL pipelines. The STB and LPSC
require that our transportation rates are reasonable and that our practices cannot unreasonably discriminate among our shippers.

U.S. Department of Transportation (DOT): We are regulated by the DOT, through the Pipeline and Hazardous Material Safety Administration (PHMSA),
under the Natural Gas Pipeline Safety Act of 1968, as amended (NGPSA), and the Hazardous Liquids Pipeline Safety Act of 1979, as amended (HLPSA). The
NGPSA and  HLPSA govern  the  design,  installation,  testing,  construction,  operation,  replacement  and  management  of  interstate  natural  gas  and  NGLs  pipeline
facilities. We have authority from PHMSA to operate certain natural gas pipeline assets under issued permits with specific conditions that allow us to operate those
pipeline assets at higher than normal operating pressures of up to 0.80 of the pipeline's Specified Minimum Yield Strength (SMYS). Operating at these pressures
allows us to transport all the existing natural gas volumes we have contracted for on those facilities with our customers. PHMSA retains discretion whether to grant
or maintain authority for us to operate our natural gas pipeline assets at higher pressures and, in the event that PHMSA should elect not to allow us to operate at
these higher pressures, it could affect our ability to transport all of our contracted quantities of natural gas on these pipeline assets, and we could incur significant
additional  costs  to  reinstate  this  authority  or  to  develop  alternate  ways  to  meet  our  contractual  obligations.  PHMSA's  regulations  also  require  transportation
pipeline operators to implement integrity management programs to comprehensively evaluate certain high risk areas, known as high consequence areas (HCAs),
high population areas (also known as moderate consequence areas (MCAs)), and Class 3 and Class 4 areas, which are determined by specific population densities
near our pipelines, as well as certain drinking water sources and unusually sensitive ecological areas, along our pipelines, and take additional safety measures to
protect people and property in these areas.

Legislation  in  the  past  decade  has  resulted  in  more  stringent  mandates  for  pipeline  safety  and  has  charged  PHMSA  with  developing  and  adopting
regulations that impose increased pipeline safety requirements on pipeline operators. In particular, the NGPSA and HLPSA were amended by the Pipeline Safety,
Regulatory Certainty, and Job Creation Act of 2011 (2011 Act) and the Protecting Our Infrastructure of Pipelines and Enhancing Safety Act of 2016 (2016 Act).
The 2011 Act increased the penalties for safety violations, established additional safety requirements for newly constructed pipelines and required studies of safety
issues that could result in the adoption of new regulatory requirements by PHMSA for existing pipelines. The 2016 Act, among other things, required PHMSA to
complete  its  outstanding  mandates  under  the  2011  Act  and  develop  new  safety  standards  for  natural  gas  storage  facilities.  Pursuant  to  the  2016  Act,  PHMSA
published  a  final  rule  in  February  2020  that  amended  the  minimum  safety  issues  related  to  natural  gas  storage  facilities,  including  wells,  wellbore  tubing  and
casing,  which  final  rule  was  amended  to  add  applicable  reporting  requirements  and  was  subsequently  published  in  July  2020.  Also,  in  October  2019,  PHMSA
published the first of three expected regulations relating to new or more stringent

7

requirements  for  certain  natural  gas  pipelines,  that  had  originally  been  proposed  in  2016  as  part  of  PHMSA's  “gas  Mega  Rule,”  which  first  final  rule  became
effective on July 1, 2020. This regulation imposed numerous requirements, including maximum allowable operating pressure (MAOP) reconfirmation through re-
verification  of  all  historical  records  for  pipelines  in  service,  which  re-certification  process  may  require  natural  gas  pipelines  installed  before  1970  (previously
excluded from certain pressure testing obligations) to be pressure tested, the periodic assessment of additional pipeline mileage outside of HCAs (in MCAs as well
as  Class  3  and  Class  4  areas),  the  reporting  of  exceedances  of  MAOP  and  the  consideration  of  seismicity  as  a  risk  factor  in  integrity  management.  Additional
amendments  to  this  October  2019  final  rule  relating  to  recordkeeping  for  gas  transmission  lines  were  published  by  PHMSA  in  July  2020.  We  are  currently
evaluating the operational and financial impact related to this final rule. The remaining rulemakings comprising the gas Mega Rule have not yet been published,
and we cannot predict when they will be finalized; however, they are expected to include revised pipeline repair criteria as well as more stringent corrosion control
requirements.

Also,  in  the  Fiscal  Year  2021  Omnibus  Appropriations  Bill  passed  by  Congress  and  made  effective  December  27,  2020,  the  Congress  reauthorized
PHMSA through fiscal year 2023 and directed the agency to move forward with several regulatory actions, including the “Pipeline Safety: Class Location Change
Requirements”  and  the  “Pipeline  Safety:  Safety  of  Gas  Transmission  and  Gathering  Pipelines”  proposed  rulemakings.  Congress  has  also  instructed  PHMSA  to
issue final regulations that will require operators of non-rural gas gathering lines and new and existing transmission and distribution pipeline facilities to conduct
certain leak detection and repair programs and to require facility inspection and maintenance plans to align with those regulations. New regulations adopted by
PHMSA may impose more stringent requirements applicable to integrity management programs and other pipeline safety aspects of our operations, which could
cause us to incur increased capital and operating costs and operational delays.

Other: Our operations are also subject to extensive federal, state and local laws and regulations relating to protection of the environment and occupational
health and safety. Such laws and regulations impose, among other things, restrictions, liabilities and obligations in connection with the generation, handling, use,
storage, transportation, treatment and disposal of various substances, including hazardous substances and waste and in connection with spills, releases, discharges
and  emissions  of  various  substances  into  the  environment.  Environmental  regulations  also  require  that  our  facilities,  sites  and  other  properties  be  operated,
maintained,  abandoned  and  reclaimed  to  the  satisfaction  of  applicable  regulatory  authorities.  Occupational  health  and  safety  regulations  establish  standards
protective of workers, both generally and within the pipeline industry. These laws, as amended from time to time, that our operations are subject to, include, for
example:

•

•

•

•

•

•

•

the Clean Air Act (CAA) and analogous state laws, which regulate air emission pollutants, greenhouse gas (GHG) emissions and reciprocating engines
subject to Maximum Achievable Control Technology standards;

the Federal Water Pollution Control Act, commonly referred to as the Clean Water Act, and analogous state laws, which establish the extent to which
waterways are subject to federal or state jurisdiction and serve to regulate the discharge of wastewater from our facilities into state and federal waters;

the Comprehensive Environmental Response, Compensation and Liability Act, commonly referred to as CERCLA, or the Superfund law, and analogous
state laws, which regulate the cleanup of hazardous substances that may have been released at properties currently or previously owned or operated by us
or locations to which we have sent hazardous substances for disposal;

the  Resource  Conservation  and  Recovery  Act  (RCRA)  and  analogous  state  laws,  which  impose  requirements  for  the  generation,  storage,  treatment,
transportation and disposal of solid and hazardous wastes at or from our facilities;

the Endangered Species Act (ESA), which restricts activities that may affect federally identified endangered and threatened species or their habitats by the
implementation of operating restrictions or a temporary, seasonal or permanent ban in affected areas;

the  National  Environmental  Policy  Act  (NEPA),  which  requires  federal  agencies  to  evaluate  major  agency  actions  having  the  potential  to  impact  the
environment and that may require the preparation of environmental assessments and more detailed environmental impact statements that may be made
available for public review and comment; and

the Occupational Safety and Health Act (OSHA) and analogous state laws, which establish workplace standards for the protection of the health and safety
of  employees,  including  the  implementation  of  hazard  communications  programs  designed  to  inform  employees  about  hazardous  substances  in  the
workplace, potential harmful effects of these substances and appropriate control measures.

Many states where we operate also have, or are developing, similar environmental or occupational health and safety legal requirements governing many
of the same types of activities, and those requirements can be more stringent than those adopted under federal laws and regulations. Failure to comply with these
federal, state and local laws and regulations may result

8

in the assessment of administrative, civil and criminal penalties, the imposition of corrective or remedial obligations, the incurrence of capital expenditures, the
occurrence of delays, denials or cancellations in permitting or the development or expansion of projects and the issuance of orders enjoining performance of some
or all of our operations in affected areas.

President Biden has indicated that he intends to pursue additional environmental regulations, whether by new legislation, executive actions or regulatory
initiatives, which may impact our operations. For example, in recent years, there have been conflicting interpretations of what waterways are subject to jurisdiction
under the Clean Water Act, with competing rulemakings being developed, and subsequently challenged in courts, by different presidential administrations. The
incoming Biden Administration may propose another interpretation of the extent of this jurisdiction, though we cannot predict the likelihood or effects of any such
proposal at this time. Similarly, President Biden has announced plans to take action with regards to climate change and signed executive orders to this effect on
January 20, 2021; for more information, see Item 1A. Risk Factors—Business Risks—Legislative and regulatory initiatives related to climate change make our
operations, as well as the operations of our fossil-fuel producer customers, subject to a series of regulatory, political, litigation and financial risks associated with
the production and processing of fossil fuels and emission of GHGs.

Historically, our environmental compliance costs have not had a material adverse effect on our results of operations, but there can be no assurance that
future  compliance  with  existing  requirements  will  not  materially  affect  us  or  that  the  current  regulatory  standards  will  not  become  more  onerous  in  the  future,
resulting in more significant costs to maintain compliance or increased exposure to significant liabilities. Note 5 in Part II, Item 8. of this Annual Report on Form
10-K contains information regarding environmental compliance.

Human Capital

At  December  31,  2020,  we  had  1,240  employees,  approximately  100  of  whom  were  included  under  collective  bargaining  agreements.  A  satisfactory

relationship exists between management and labor.

Hiring and retaining the right people is critical to our long-term strategic success. We have programs in place to help employees build their knowledge,
skills  and  experience,  as  well  as  to  guide  their  career  development.  A  cornerstone  of  our  human  capital  strategy  is  our  commitment  to  fostering  a  diverse  and
inclusive  work  environment,  where  all  people  are  respected  and  encouraged  to  contribute  their  ideas.  Employing  individuals  with  different  backgrounds  and
experiences helps meet the diverse needs of all our stakeholders.

We are part of a critical infrastructure industry whose customers and communities depend upon us to provide safe and reliable service. Our employees are
essential to ensuring we continue to meet these objectives, and we consider safety in our day-to-day activities to be our primary core value. Our emphasis on safety
extends to our approach to managing the risk of operational disruptions due to coronavirus disease 2019 (COVID-19), and we have maintained full, continuous
operations throughout the pandemic.

Item 1A. Risk Factors

Our business faces many risks and uncertainties. We have described below the material risks facing us. These risks and uncertainties could lead to events
or circumstances that may have a material adverse effect on our business, financial condition, results of operations or cash flows. There may be additional risks that
we do not yet know of or that we do not currently perceive to be as material that may also materially adversely affect our business, financial condition, results of
operations or cash flows.

All of the information included in this Annual Report on Form 10-K and any subsequent reports we may file with the SEC or make available to the public

should be carefully considered and evaluated before investing in any securities issued by us.

Business Risks

Our natural gas transportation and storage operations are subject to extensive regulation by the FERC, including rules and regulations related to the rates we
can charge for our services and our ability to construct or abandon facilities. We may not be able to recover the full cost of operating our pipelines, including
earning a reasonable return.

Our natural gas transportation and storage operations are subject to extensive regulation by the FERC, including the types, rates and terms of services we
may offer to our customers, construction of new facilities, creation, modification or abandonment of services or facilities and recordkeeping and relationships with
affiliated companies. An adverse FERC action in any of these areas could affect our ability to compete for business, construct new facilities, offer new services or
recover  the  full  cost  of  operating  our  pipelines.  This  regulatory  oversight  can  result  in  longer  lead  times  to  develop  and  complete  any  future  project  than
competitors that are not subject to the FERC's regulations. The FERC can also deny us the right to abandon certain facilities from service.

The  FERC  also  regulates  the  rates  we  can  charge  for  our  natural  gas  transportation  and  storage  operations.  For  our  cost-based  services,  the  FERC
establishes both the maximum and minimum rates we can charge. The basic elements that the FERC considers are the costs of providing service, the volumes of
gas being transported, the rate design, the allocation of costs between services, the capital structure and the rate of return a pipeline is permitted to earn. We may
not be able to recover our costs, including certain costs associated with pipeline integrity, through existing or future rates.

The FERC and/or our customers could challenge the maximum applicable rates that any of our regulated pipelines are allowed to charge in accordance
with  Section  5  of  the  NGA.  Potential  legislation  that  would  amend  Section  5  of  the  NGA  to  add  refund  provisions  could  increase  the  likelihood  of  such  a
challenge. If such a challenge is successful for any of our pipelines, the revenues associated with transportation and storage services the pipeline provides pursuant
to cost-of-service rates could materially decrease in the future, which would adversely affect the revenues on that pipeline going forward.

Legislative and regulatory initiatives relating to pipeline safety that require the use of new or more prescriptive compliance activities, substantial changes to
existing integrity management programs or withdrawal of regulatory waivers could subject us to increased capital and operating costs and operational delays.

Our interstate pipelines are subject to regulation by PHMSA which is part of the DOT. PHMSA regulates the design, installation, testing, construction,
operation and maintenance of existing interstate natural gas and NGLs pipeline facilities. PHMSA regulation currently requires pipeline operators to implement
integrity management programs, including frequent inspections, correction of certain identified anomalies and other measures to promote pipeline safety in HCAs,
MCAs,  and  Class  3  and  Class  4  areas,  as  well  as  in  areas  unusually  sensitive  to  environmental  damage  and  commercially  navigable  waterways.  States  have
jurisdiction  over  certain  of  our  intrastate  pipelines  and  have  adopted  regulations  similar  to  existing  PHMSA  regulations.  State  regulations  may  impose  more
stringent requirements than found under federal law that affect our intrastate operations. Compliance with these rules over time generally has resulted in an overall
increase in our maintenance costs. The imposition of new or more stringent pipeline safety rules applicable to natural gas or NGL pipelines, or any issuance or
reinterpretation of guidance from PHMSA or any state agencies with respect thereto, could cause us to install new or modified safety controls, pursue additional
capital projects or conduct maintenance programs on an accelerated basis, any or all of which tasks could result in us incurring increased capital and operating
costs, experiencing operational delays and suffering potential adverse impacts to our operations or our ability to reliably serve our customers. Requirements that
are imposed under the 2011 Act or the more recent 2016 Act may also increase our capital and operating costs or impact the operation of our pipelines. In the
Fiscal Year 2021 Omnibus Appropriations Bill, Congress reauthorized PHMSA through fiscal year 2023 and directed the agency to move forward with several
regulatory actions. See Part I, Item 1. Business—Government Regulation—U.S. Department of Transportation of this Annual Report on Form 10-K for further
discussion on pipeline safety matters. Any

10

 
new pipeline  safety legislation  or implementing  regulations could impose more stringent or costly compliance obligations on us and could require us to pursue
additional capital projects or conduct integrity or maintenance programs on an accelerated basis, any or all of which tasks could result in us incurring increased
operating costs that could have a material adverse effect on our costs of providing transportation services.

We have entered into certain firm transportation contracts with shippers on certain of our expansion projects that utilize the design capacity of certain of
our pipeline assets, based upon the authority we received from PHMSA to operate those pipelines at higher than normal operating pressures of up to 0.80 of the
pipeline's SMYS under issued permits with specific conditions. PHMSA retains discretion to withdraw or modify this authority. If PHMSA were to withdraw or
materially modify such authority, it could affect our ability to transport all of our contracted quantities of natural gas on these pipeline assets and we could incur
significant additional costs to reinstate this authority or to develop alternate ways to meet our contractual obligations.

Our actual construction and development costs could exceed our forecasts; our anticipated cash flow from construction and development projects will not be
immediate; and our construction and development projects may not be completed on time or at all.

We  are  and  have  been  engaged  in  several  construction  projects  involving  our  existing  assets  and  the  construction  of new facilities  for  which we have
expended or will expend significant capital. We expect to continue to engage in the construction of additional growth projects and modifications of our system.
When we build a new pipeline or expand or modify an existing facility, the design, construction and development occurs over an extended period of time, and we
will  not  receive  any  revenue  or  cash  flow  from  that  project  until  after  it  is  placed  into  commercial  service.  On  our  interstate  pipelines,  there  are  several  years
between when the project is announced and when customers begin using the new facilities. During this period we spend capital and incur costs without receiving
any  of  the  financial  benefits  associated  with  the  projects.  The  construction  of  new  assets  involves  regulatory  (federal,  state  and  local),  landowner  opposition,
environmental, activist, legal, political, materials and labor costs, as well as operational and other risks that are difficult to predict and some are beyond our control.
A project may not be completed on time or at all due to a variety of factors, may be impacted by significant cost overruns or may be materially changed prior to
completion as a result of developments or circumstances that we are not aware of when we commit to the project. Any of these events could result in material
unexpected costs or have a material adverse effect on our ability to realize the anticipated benefits from our growth projects.

Legislative and regulatory initiatives related to climate change make our operations, as well as the operations of our fossil-fuel producer customers, subject to
a series of regulatory, political, litigation and financial risks associated with the production and processing of fossil fuels and emission of GHGs.

The threat of climate change continues to attract considerable attention in the U.S. and in foreign countries. Numerous proposals have been made and
could continue to be made at the international, national, regional and state levels of government to monitor and limit existing emissions of GHGs as well as to
restrict  or  eliminate  such  future  emissions,  which  makes  our  operations  as  well  as  the  operations  of  our  fossil  fuel  producer  customers  subject  to  a  series  of
regulatory, political, litigation and financial risks associated with the production and processing of fossil fuels and emission of GHGs.

In  the  U.S.,  no  comprehensive  climate  change  legislation  has  been  implemented  at  the  federal  level.  With  the  U.S.  Supreme  Court  finding  that  GHG
emissions  constitute  a  pollutant  under  the  CAA,  the  Environmental  Protection  Agency  (EPA)  has  adopted  several  rules  that,  among  other  things,  establish
construction and operating permit reviews for GHG emissions from certain large stationary sources, require the monitoring and annual reporting of GHG emissions
from certain natural gas system sources in the U.S., implement New Source Performance Standards (NSPS) directing the reduction of methane from certain new,
modified or reconstructed facilities in the natural gas sector, and together with the DOT, implement GHG emissions limits on vehicles manufactured for operation
in the U.S. In recent  years, there  has been  considerable  uncertainty  surrounding  regulation  of methane  emissions,  as the EPA under the Obama Administration
published  final  regulations  under  the  CAA  establishing  new  performance  standards  for  methane  in  2016,  but  since  that  time  the  EPA  under  the  Trump
Administration has undertaken several measures, including publishing in September 2020 final rule policy and technical amendments to the NSPS, for stationary
sources of air emissions. The policy amendments, effective September 14, 2020, notably removed the transmission and storage sector from the regulated source
category and rescinded methane and volatile organic compound (VOC) requirements for the remaining sources that were established by former President Obama’s
Administration;  whereas  the  technical  amendments,  effective  November  16,  2020,  included  changes  to  fugitive  emissions  monitoring  and  repair  schedules  for
gathering  and  boosting  compressor  stations  and  low-production  wells,  and  recordkeeping  and  reporting  requirements.  Various  states  and  industry  and
environmental groups are separately challenging both the original 2016 standards and the EPA's September 2020 final rules, and on January 20, 2021, President
Biden issued an executive order, that directed the EPA to reconsider the technical amendments and issue a proposed rule suspending, revising or rescinding

11

    
those amendments by no later than September 2021. A reconsideration of the September 2020 policy amendments is expected to follow. The January 20, 2021,
executive  order  also  directed  the  establishment  of  new  methane  and  VOC  standards  applicable  to  existing  oil  and  gas  operations,  including  the  production,
transmission,  processing  and  storage  segments.  Various  states  and  groups  of  states  have  adopted  or  are  considering  adopting  legislation,  regulations  or  other
regulatory initiatives that are focused on such areas as GHG cap and trade programs, carbon taxes, reporting and tracking programs and restriction of emissions. At
the international level, the non-binding Paris Agreement requests that nations limit their GHG emissions through individually-determined reduction goals every
five years after 2020. Although the U.S. had withdrawn from the Paris Agreement, President Biden has issued executive orders recommitting the U.S. to the Paris
Agreement and calling for the federal government to begin formulating the U.S.’ nationally determined emissions reduction goal under the agreement. With the
U.S. recommitting to the Paris Agreement, additional executive orders may be issued or federal legislation or regulatory initiatives may be adopted to achieve the
Paris Agreement’s goals.

Governmental, scientific and public concern over the threat of climate change arising from GHG emissions has resulted in increasing political risks in the
U.S.  On  January  27,  2021,  President  Biden  issued  an  executive  order  that  commits  to  substantial  action  on  climate  change,  calling  for,  among  other  things,
suspending  the  issuance  of  new  leases  for  oil  and  gas  development  on  federal  lands,  pending  completion  of  a  review  of  leasing  and  permitting  practices  and
expanding on the Acting Secretary of the U.S. Department of the Interior's January 20, 2020, order, effective immediately, that suspends new oil and gas leases and
drilling permits on federal lands and waters for a period of 60 days. The executive order also called for the increased use of zero-emissions vehicles by the federal
government, the elimination of subsidies provided to the fossil fuel industry, and an increased emphasis on climate-related risks across government agencies and
economic sectors. Legal challenges to these suspensions are expected, with at least one industry group filing a lawsuit on January 27, 2021, in Wyoming federal
district  court  and  seeking  to  have  the  moratorium  declared  invalid.  The  new  presidential  administration  could  also  pursue  the  imposition  of  more  restrictive
requirements for the establishment of pipeline infrastructure or the permitting of LNG export facilities, as well as more restrictive GHG emissions limitations for
oil and gas facilities. Litigation risks are also increasing, as a number of cities and other local governments have sought to bring suit against fossil fuel producer
companies in state or federal court, alleging, that such companies created public nuisances by producing fuels that contributed to global warming effects, such as
rising sea levels, and are responsible for roadway and infrastructure damages as a result, or alleging that the companies have been aware of the adverse effects of
climate change for some time but defrauded their investors or customers by failing to adequately disclose those impacts.

There  are  also  increasing  financial  risks  for  fossil  fuel  energy  companies  as  investors  invested  in  fossil  fuel  energy  companies  become  increasingly
concerned  about  the  potential  effects  of  climate  change  and  may  elect  in  the  future  to  shift  some  or  all  of  their  investments  into  non-energy  related  sectors.
Institutional lenders who provide financing to fossil fuel energy companies also have become more attentive to sustainable lending practices and some of them may
elect not to provide funding for fossil fuel energy companies. Additionally, there is the possibility that financial institutions will be required to adopt policies that
limit  funding  for  fossil  fuel  energy  companies.  Recently,  the  Federal  Reserve  announced  that  it  has  joined  the  Network  for  Greening  the  Financial  System,  a
consortium  of  financial  regulators  focused  on  addressing  climate-related  risks  in  the  financial  sector.  This  could  make  it  more  difficult  to  secure  funding  for
exploration and production or midstream energy business activities.

The adoption and implementation of new or more stringent international, federal or state legislation, regulations or other regulatory initiatives that impose
more stringent standards for GHG emissions from the oil and gas sector or otherwise restrict the areas in which this sector may produce fossil fuels or generate
GHG emissions could result in increased costs of compliance or costs of consuming, and thereby reduce demand for fossil fuels, which could reduce demand for
our transportation and storage services. Political, litigation and financial risks may result in our fossil fuel producer customers restricting or canceling production
activities,  incurring  liability  for  infrastructure  damages  as  a  result  of  climatic  changes  or  impairing  their  ability  to  continue  to  operate  in  an  economic  manner,
which also could reduce demand for our services. Moreover, the increased competitiveness of alternative energy sources (such as wind, solar, geothermal, tidal and
biofuels) could reduce demand for hydrocarbons, and for our services. Finally, increasing concentrations of GHG in the earth's atmosphere may produce climate
changes that have significant physical effects, such as increased frequency and severity of storms, droughts, floods, rising sea levels and other climatic events.

The  outbreak  of  COVID-19  and  the  measures  to  mitigate  the  spread  of  COVID-19  could  materially  adversely  affect  our  business,  financial  condition  and
results of operations and those of our customers, suppliers and other business partners.

The  global  outbreak  of  COVID-19  has  materially  negatively  impacted  worldwide  economic  and  commercial  activity  and  financial  markets  and  has
impacted global demand for oil and petrochemical products. COVID-19 has also resulted in significant business and operational disruptions, including business
closures, supply chain disruptions, travel restrictions, stay-at-home orders and limitations on the availability of workforces. If significant portions of our workforce
are unable to work

12

effectively, including because of illness, quarantines, government actions, facility closures or other restrictions in connection with COVID-19, our business could
be materially adversely affected. We may also be unable to perform fully on our contracts, and our costs may increase as a result of the COVID-19 outbreak. These
cost increases may not be fully recoverable. It is possible that the continued spread of COVID-19 could also further cause disruption in our customers' business;
cause  delay,  or  limit  the  ability  of  our  customers  to  perform,  including  in  making  timely  payments  to  us;  and  cause  other  unpredictable  events.  The  impact  of
COVID-19 has impacted capital markets, which may impact our customers' financial position, and recoverability of our receivables from our customers may be at
risk.  The  full  impact  of  COVID-19  is  unknown  and  continues  to  evolve.  The  extent  to  which  COVID-19  negatively  impacts  our  business  and  operations  will
depend on the severity, location and duration of the effects and spread of COVID-19, the continued actions undertaken by national, regional and local governments
and health officials to contain the virus or treat its effects, and how quickly and to what extent economic conditions improve and normal business and operating
conditions resume. It might also have the effect of increasing several of the other risk factors contained herein.

Changes in energy prices, including natural gas, oil and NGLs, impact the supply of and demand for those commodities, which impact our business.

Our customers, especially producers and certain plant operators, are directly impacted by changes in commodity prices. The prices of natural gas, oil and
NGLs fluctuate in response to changes in both domestic and worldwide supply and demand, market uncertainty and a variety of additional factors, including for
natural gas the realization of potential LNG exports and demand growth within the power generation market. The recent volatility in the pricing levels of natural
gas, oil and NGLs has adversely  affected  the businesses of certain of our producer customers and could result in defaults  or the non-renewal  of our contracted
capacity when existing contracts expire. The current erosion in commodity prices could affect the operations of certain of our industrial customers, including the
temporary closure or reduction of plant operations, resulting in decreased deliveries to those customers. Future increases in the price of natural gas and NGLs could
make alternative energy and feedstock sources more competitive and decrease demand for natural gas and NGLs. A reduced level of demand for natural gas and
NGLs could diminish the utilization of capacity on our systems and reduce the demand for our services.

The price differentials between natural gas supplies and market demand for natural gas have reduced the transportation rates that we can charge on certain
portions of our pipeline systems.

Each year a portion of our firm natural gas transportation contracts expire and need to be replaced or renewed. Over the past several years, as a result of
market conditions, we have renewed some expiring contracts at lower rates or for shorter terms than in the past. The transportation rates we are able to charge
customers are heavily influenced by market trends (both short and longer term), including the available supply, geographical location of natural gas production, the
competition  between  producing  basins,  competition  with  other  pipelines  for  supply  and  markets,  the  demand  for  gas  by  end-users  such  as  power  plants,
petrochemical  facilities  and  LNG  export  facilities  and  the  price  differentials  between  the  gas  supplies  and  the  market  demand  for  the  gas  (basis  differentials).
Market conditions have resulted in a sustained narrowing of basis differentials on certain portions of our pipeline system, which has reduced transportation rates
that can be charged in the affected areas and adversely affected the contract terms we can secure from our customers for available transportation capacity and for
contracts being renewed or replaced. We expect these market conditions to continue.

A failure in our computer systems or a cybersecurity attack on any of our facilities, or those of third parties, could cause substantial damage and may affect
adversely our ability to operate our business.

We have become more reliant on technology to help increase efficiency in our business processes. Our businesses are dependent upon our operational and
financial computer systems to process the data necessary to conduct almost all aspects of our business, including the operation of our pipeline and storage facilities
and the recording and reporting of commercial and financial transactions. Any failure of our computer systems, or those of our customers, suppliers or others with
whom we do business, could materially disrupt our ability to operate our business.

At the same time, the U.S. government has issued public warnings that indicate that energy assets might be specific targets of cybersecurity threats. Our
technologies, systems and networks, and those of our vendors, suppliers and other business partners, may become the target of cyberattacks or information security
breaches that could result in the unauthorized release, gathering, monitoring, misuse, loss or destruction of proprietary and other information, significant damage to
property, personal injury or loss of life, substantial financial damage or other disruption of operations. In addition, certain cyber-incidents may remain undetected
for  an  extended  period.  As  cyber-incidents  continue  to  evolve,  legislation  could  be  enacted  to  mitigate  cyber-threats.  This  will  likely  require  us  to  expend
additional resources to continue to modify or enhance our protective measures or to investigate and remediate any vulnerability to cyber-incidents at significantly
increased  costs. Our insurance  coverage for cyberattacks  may not be sufficient to cover all the losses we may experience  as a result of such cyberattacks.  Any
cyberattacks

13

that affect our facilities, or those of our customers, suppliers or others with whom we do business could have a material adverse effect on our business, cause us a
financial loss and/or damage our reputation.

We are exposed to credit risk relating to default or bankruptcy by our customers.

Credit risk relates to the risk of loss resulting from the default by a customer of its contractual obligations or the customer filing bankruptcy. We have
credit  risk  with  both  our  existing  customers  and  those  supporting  our  growth  projects.  Credit  risk  exists  in  relation  to  our  growth  projects,  both  because  the
expansion customers make long-term firm capacity commitments to us for such projects and certain of those expansion customers agree to provide credit support
as construction for such projects progresses. If a customer fails to post the required credit support or defaults during the growth project process, overall returns on
the  project  may be  reduced  to the extent  an adjustment  to  the scope of the project  occurs  or  we are  unable  to replace  the  defaulting  customer  with a customer
willing to pay similar rates. In 2020 and 2019, two expansion customers declared bankruptcy for which we were able to use the credit support obtained during the
growth project process to cover a portion of their remaining long-term commitment. For more information, refer to Note 5 in Part II, Item 8. of this Annual Report
on Form 10-K.

Our credit exposure also includes receivables for services provided, future performance under firm agreements and volumes of gas owed by customers for

imbalances or gas loaned by us to them under certain NNS and PAL services.

We rely on a limited number of customers for a significant portion of revenues.

For 2020, one customer comprised approximately 10% of our 2020 operating revenues. Additionally, the top ten customers holding firm capacity under
firm  agreements  comprised  approximately  40%  of  our  total  projected  operating  revenues.  If  any  of  our  significant  customers  have  credit  or  financial  problems
which result in bankruptcy, a delay or failure to pay for services provided by us, to post the required credit support for construction associated with our growth
projects or existing contracts or to repay the gas they owe us, it could have a material adverse effect on our revenues.

Our revolving credit facility contains operating and financial covenants that restrict our business and financing activities.

Our revolving  credit  facility  contains  operating  and  financial  covenants  that  may  restrict  our  ability  to  finance  future  operations  or  capital  needs  or  to
expand or pursue business activities. Our credit agreement limits our ability to make loans or investments, make material changes to the nature of our business,
merge, consolidate or engage in asset sales, or grant liens or make negative pledges. This agreement also requires us to maintain a ratio of consolidated debt to
consolidated EBITDA (as defined in the agreement) of not more than 5.0 to 1.0, or up to 5.5 to 1.0 for the three quarters following a qualified acquisition or series
of acquisitions, where the purchase price exceeds $100.0 million over a rolling 12-month period, which limits the amount of additional indebtedness we can incur
to grow our business, and could require us to reduce indebtedness if our earnings before interest, income taxes, depreciation and amortization (EBITDA) decreases
to a level that would cause us to breach this covenant. Future financing agreements we may enter into could contain similar or more restrictive covenants or may
not be as favorable as those under our existing indebtedness.

Our  ability  to  comply  with  the  covenants  and  restrictions  contained  in  our  credit  agreement  may  be  affected  by  events  beyond  our  control,  including
economic, financial and market conditions. If market, economic conditions or our financial performance deteriorate, our ability to comply with these covenants
may be impaired. If we are not able to incur additional indebtedness, we may be required to seek other sources of funding that may be on less favorable terms. If
we default under our credit agreement or another financing agreement, significant additional restrictions may become applicable. In addition, a default could result
in a significant portion of our indebtedness becoming immediately due and payable, and our lenders could terminate their commitment to make further loans to us.
If such event occurs, we would not have, and may not be able to obtain, sufficient funds to make these accelerated payments.

Our substantial indebtedness could affect our ability to meet our obligations and may otherwise restrict our activities.

As of December 31, 2020, we had $3.5 billion in principal amount of long-term debt outstanding, including amounts borrowed under our revolving credit
facility. This level of debt requires significant interest payments. Our inability to generate sufficient cash flow to satisfy our debt obligations, or to refinance our
obligations  on  commercially  reasonable  terms,  would  have  a  material  adverse  effect  on  our  business.  Our  substantial  indebtedness  could  have  important
consequences. For example, it could:

•

limit our ability to borrow money for our working capital, capital expenditures, debt service requirements or other general partnership purposes;

14

 
•

•

•

impact the ratings received from credit rating agencies;

increase our vulnerability to general adverse economic and industry conditions; and

limit our ability to respond to business opportunities, including growing our business through acquisitions.

We are permitted, under our revolving credit facility and the indentures governing our notes, to incur additional debt, subject to certain limitations under
our revolving credit facility and, in the case of unsecured debt, under the indentures governing the notes. If we incur additional debt, our increased leverage could
also result in the consequences described above.

We have a holding company structure in which our subsidiaries conduct our operations and own our operating assets, which may affect our ability to fulfill
our debt obligations.

We  are  a  partnership  holding  company  and  our  operating  subsidiaries  conduct  all  of  our  operations  and  own  all  of  our  operating  assets.  We  have  no
significant assets other than the ownership interests in our subsidiaries. As a result, our ability to fulfill our debt obligations depends on the performance of our
subsidiaries  and  their  ability  to  distribute  funds  to  us.  The  ability  of  our  subsidiaries  to  make  distributions  to  us  may  be  restricted  by,  among  other  things,  the
provisions  of existing  and future  indebtedness,  applicable  state  partnership  and  limited  liability  company  laws and  other  laws and  regulations,  including  FERC
policies.

Limited access to the debt markets and increases in interest rates could adversely affect our business.

We  anticipate  funding  our  capital  spending  requirements  through  our  available  financing  options,  including  cash  generated  from  operations  and
borrowings under our revolving credit facility. Changes in the debt markets, including market disruptions, limited liquidity, and an increase in interest rates, may
increase the cost of financing as well as the risks of refinancing maturing debt. This may affect our ability to raise needed financing and reduce the amount of cash
available to fund our operations or growth projects. If the debt markets were not available, it is not certain if other adequate financing options would be available to
us on terms and conditions that we would find acceptable.

Any  disruption  in  the  debt  markets  could  require  us  to  take  additional  measures  to  conserve  cash  until  the  markets  stabilize  or  until  we  can  arrange
alternative  credit  arrangements  or  other  funding  for  our  business  needs.  Such  measures  could  include  reducing  or  delaying  business  activities,  reducing  our
operations to lower expenses and reducing other discretionary uses of cash. We may be unable to execute our growth strategy or take advantage of certain business
opportunities, any of which could negatively impact our business.

We do not own all of the land on which our pipelines, storage and other facilities are located, which could result in disruptions to our operations.

Substantial portions of our pipelines, storage and other facilities are constructed and maintained on property owned by others pursuant to rights-of-way,
easements, permits, licenses or consents, and we are subject to the possibility of more onerous terms and/or increased costs to retain necessary land use rights if we
do not have valid land use rights or if such land use rights lapse or terminate. Some of the rights to construct and operate our pipelines, storage or other facilities on
land owned by third parties and governmental agencies that we obtain are for specific periods of time. We cannot guarantee that we will always be able to renew,
when necessary, existing land use rights or obtain new land use rights without experiencing significant costs or experiencing landowner opposition. Any loss of
these land use rights with respect to the operation of our pipelines, storage and other facilities, through our inability to renew right-of-way or easement contracts or
permits, licenses, consents or otherwise, could have a material adverse effect on our operations.

Rising sea levels, subsidence and erosion could damage our pipelines and the facilities that serve our customers, particularly along coastal waters and offshore
in the Gulf of Mexico.

Our  pipeline  operations  along  coastal  waters  and  offshore  in  the  Gulf  of  Mexico  could  be  impacted  by  rising  sea  levels,  subsidence  and  erosion.
Subsidence  issues  are  also  a  concern  for  our  pipelines  at  major  river  crossings.  Rising  sea  levels,  subsidence  and  erosion  could  cause  serious  damage  to  our
pipelines,  which  could  affect  our  ability  to  provide  transportation  services  or  result  in  leakage,  migration,  releases  or  spills  from  our  operations  to  surface  or
subsurface soils, surface water, groundwater or offshore waters, which could result in liability, remedial obligations and/or otherwise have a negative impact on
continued operations. Such rising sea levels, subsidence and erosion processes could impact our customers who operate along coastal waters or offshore in the Gulf
of Mexico, and they may be unable to utilize our services. Rising sea levels, subsidence

15

    
and  erosion  could  also  expose  our  operations  to  increased  risks  associated  with  severe  weather  conditions  and  other  adverse  events  and  conditions,  such  as
hurricanes  and  flooding.  As  a  result,  we  may  incur  significant  costs  to  repair  and  preserve  our  pipeline  infrastructure.  In  recent  years,  local  governments  and
landowners have filed lawsuits in Louisiana against energy companies, alleging that their operations contributed to increased coastal rising seas and erosion and
seeking substantial damages.
We may not be successful in executing our strategy to grow and diversify our business.

We  rely  primarily  on  the  revenues  generated  from  our  natural  gas  transportation  and  storage  services.  Negative  developments  in  these  services  have
significantly  greater  impact  on  our  financial  condition  and  results  of  operations  than  if  we  maintained  more  diverse  assets.  Our  ability  to  grow,  diversify  and
increase cash flows will depend, in part, on our ability to expand our existing business lines and to close and execute on accretive acquisitions. We may not be
successful in acquiring or developing such assets or may do so on terms that ultimately are not profitable. Any such transactions involve potential risks that may
include, among other things:

•

•

•

•

•

•

•

the diversion of management's and employees' attention from other business concerns;

inaccurate assumptions about volume, revenues and project costs, including potential synergies;

a decrease in our liquidity as a result of our using available cash or borrowing capacity to finance the acquisition or project;

a significant increase in our interest expense or financial leverage if we incur additional debt to finance the acquisition or project or if we make inaccurate
assumptions about the overall costs of debt;

an inability to hire, train or retain qualified personnel to manage and operate the acquired business and assets or the developed assets;

unforeseen difficulties operating in new product areas or new geographic areas; and

changes in regulatory requirements or delays of regulatory approvals.

Additionally, acquisitions also contain the following risks:

•

•

•

•

an inability to integrate successfully the businesses we acquire;

the assumption of unknown liabilities for which we are not indemnified, for which our indemnity is inadequate or for which our insurance policies may
exclude from coverage;

limitations on rights to indemnity from the seller; and

customer or key employee losses of an acquired business.

Our ability to replace expiring gas storage contracts at attractive rates or on a long-term basis and to sell short-term services at attractive rates or at all are
subject to market conditions.

We own and operate substantial natural gas storage facilities. The market for the storage and PAL services that we offer is impacted by the factors and
market conditions discussed above for our transportation services, and is also impacted by natural gas price differentials between time periods, such as winter to
summer (time period price spreads), and the volatility in time period price spreads. When market conditions cause a narrowing of time period price spreads and a
decline in the price volatility of natural gas, these factors adversely impact the rates we can charge for our storage and PAL services.

Failure to comply with environmental or worker safety laws and regulations or an accidental release of pollutants into the environment may cause us to incur
significant costs and liabilities.

Our operations are subject to federal, state and local laws and regulations relating to protection of worker safety or the environment. These laws include,
for  example,  the  CAA,  the  Clean  Water  Act,  CERCLA,  the  RCRA,  ESA,  NEPA,  OSHA  and  analogous  state  laws.  These  laws  and  regulations  may  restrict  or
impact our business activities, including requiring the acquisition or renewal of permits or other approvals to conduct regulated activities, restricting the manner in
which we handle

16

or dispose of wastes, imposing remedial obligations to remove or mitigate contamination resulting from a spill or other release, requiring capital expenditures to
comply with pollution control requirements and imposing safety and health criteria addressing worker protection. Failure to comply with these laws and regulations
may  trigger  a  variety  of  administrative,  civil  and  criminal  enforcement  measures,  including  the  assessment  of  monetary  penalties,  the  imposition  of  remedial
requirements, the incurrence of capital expenditures, the occurrence of delays, denials or cancellations in the permitting or performance or expansion of projects
and the issuance of orders enjoining future operations in a particular area. Under certain of these environmental laws and regulations, we could be subject to joint
and several or strict liability for the removal or remediation of previously released pollutants or property contamination regardless of whether we were responsible
for the release or contamination or if our operations were not in compliance with all laws. We may not be able to recover some or any of the costs incurred from
insurance. Stricter environmental or worker safety laws, regulations or enforcement policies could significantly increase our operational or compliance costs and
compliance with new or more stringent environmental legal requirements could delay or prohibit our ability to obtain permits for operations or require us to install
additional pollution control equipment. For example, in April 2020, the federal district court for the District of Montana determined that the U.S. Army Corps of
Engineers (the Corps) Clean Water Act Section 404 Nationwide Permit 12 (NWP 12) failed to comply with consultation requirements under the federal ESA. The
district court vacated NWP 12 and enjoined the issuance of new authorizations for oil and gas pipeline projects. While the district court's order has subsequently
been limited pending appeal and NWP 12 authorizations remain available for certain oil and gas pipeline projects, we cannot predict the ultimate outcome of this
case  and  its  impacts  to  the  Nationwide  Permit  program.  Additionally,  in  response  to  the  vacatur,  on  January  13,  2021,  the  Corps  published  a  reissuance  of  a
restructured NWP 12 for oil and natural gas pipeline activities that separated certain utilities formerly covered under the permit into other NWPs. While the rule is
effective  March  15,  2021,  the  rule  may  be  subject  to  further  revisions  or  suspension  under  the  Biden  Administration.  While  the  full  extent  and  impact  of  the
vacatur is unclear at this time, any disruption in our ability to obtain coverage under NWP 12 or other general permits may result in increased costs and project
delays if we are forced to seek individual permits from the Corps. See Part I, Item 1. Business—Government Regulation—Other of this Annual Report on Form 10-
K for further discussion on environmental matters.

Our operations are subject to catastrophic losses, operational hazards and unforeseen interruptions for which we may not be adequately insured.

There  are  a  variety  of  operating  risks  inherent  in  transporting  and  storing  natural  gas,  ethylene  and  NGLs,  such  as  leaks  and  other  forms  of  releases,
explosions, fires, cyber-attacks and mechanical problems, which could have catastrophic consequences. Additionally, the nature and location of our business may
make  us  susceptible  to  catastrophic  losses  from  hurricanes  or  other  named  storms,  particularly  with  regard  to  our  assets  in  the  Gulf  Coast  region,  windstorms,
earthquakes,  hail,  and  other  severe  weather.  Any  of  these  or  other  similar  occurrences  could  result  in  the  disruption  of  our  operations,  substantial  repair  costs,
personal injury or loss of life, significant damage to property, environmental pollution, impairment of our operations and substantial financial losses. The location
of pipelines in HCAs, which includes populated areas, residential areas, commercial business centers and industrial sites, could significantly increase the level of
damages resulting from some of these risks.

We currently possess property, business interruption, cyber threat and general liability insurance, but proceeds from such insurance coverage may not be
adequate for all liabilities or expenses incurred or revenues lost. Moreover, such insurance may not be available in the future at commercially reasonable costs and
terms. The insurance coverage we do obtain may contain large deductibles or fail to cover certain events, hazards or all potential losses.

Our business requires the retention and recruitment of a skilled workforce and the loss of such workforce could result in the failure to implement our business
plans.

Our operations and management require the retention and recruitment of a skilled executive team and workforce including engineers, technical personnel
and  other  professionals.  In  addition,  many  of  our  current  employees  are  approaching  retirement  age  and  have  significant  institutional  knowledge  that  must  be
transferred to other employees. If we are unable to retain our current employees, successfully complete the knowledge transfer and/or recruit new employees of
comparable knowledge and experience, our business could be negatively impacted.

Our business is highly competitive.

The principal elements of competition among pipeline systems are availability of capacity, rates, terms of service, access to gas supplies, flexibility and
reliability of service. Additionally, the FERC's policies promote competition in natural gas markets by increasing the number of natural gas transportation options
available to our customer base. Increased competition could reduce the volumes of product we transport or store or, in instances where we do not have long-term
contracts with fixed rates, could cause us to decrease the transportation or storage rates we can charge our customers. Competition could intensify

17

the negative impact of factors that adversely affect the demand for our services, such as adverse economic conditions, weather, higher fuel costs and taxes or other
regulatory actions that increase the cost, or limit the use, of products we transport and store.

Possible terrorist activities or military actions could adversely affect our business.

The  continued  threat  of  terrorism  and  the  impact  of  retaliatory  military  and  other  action  by  the  U.S.  and  its  allies  might  lead  to  increased  political,
economic  and  financial  market  instability  and  volatility  in  prices  for  natural  gas,  which  could  affect  the  markets  for  our  natural  gas  transportation  and  storage
services. While we are taking steps that we believe are appropriate to increase the security of our assets, we may not be able to completely secure our assets or
completely protect them against a terrorist attack.

Item 2. Properties

We are headquartered in approximately 103,000 square feet of leased office space located in Houston, Texas. We also have approximately 60,000 square
feet  of  leased  office  space  in  Owensboro,  Kentucky.  Our  operating  subsidiaries  own  their  respective  pipeline  and  storage  systems  in  fee.  However,  substantial
portions of these systems are constructed and maintained on property owned by others pursuant to rights-of-way, easements, permits, licenses or consents. Our

Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations (MD&A)

Overview

We operate in the midstream portion of the natural gas and NGLs industry, providing transportation and storage for those commodities. Refer to Part I,
Item  1. Business,  of  this  Annual  Report  on Form  10-K  for  further  discussion  of  our  operations  and  business.  We  are  not  in  the  business  of  buying  and  selling
natural gas and NGLs other than for system management purposes, but changes in natural gas and NGLs prices may impact the volumes of natural gas or NGLs
transported  and  stored  by  customers  on  our  systems.  We  conduct  all  of  our  business  through  our  operating  subsidiaries  as  one  reportable  segment.  Due  to  the
capital-intensive nature of our business, our operating costs and expenses typically do not vary significantly based upon the amount of products transported, with
the exception of fuel consumed at our compressor stations and not included in a fuel tracker, which is netted with fuel retained on our Consolidated Statements of
Income. Please refer to Part I, Item 1. Business, for further discussion of the services that we offer and our customer mix.

Current Events

In 2020, the COVID-19 pandemic and measures to mitigate the spread of COVID-19 significantly impacted the world and the U.S. An excess supply of
energy products also led to disruptions in the energy sector and volatility in energy prices early in 2020, with a partial recovery of prices and demand occurring in
the latter half of 2020. Our operations are considered essential critical infrastructure under current Cybersecurity and Infrastructure Security Agency guidelines,
which allowed us to remain operating during the pandemic. As a result, the impacts from COVID-19 and the volatile energy prices have not been significant to our
business,  though  some  of  our  customers  have  been  and  continue  to  be  directly  impacted  by  COVID-19  and  the  volatility  in  commodity  prices.  In  2020,  we
transported approximately 3.2 Tcf of natural gas, or an 8% increase from 2019. Refer to Note 5 in Part II, Item 8. of this Annual Report on Form 10-K for further
information about a producer customer bankruptcy in 2020.

Firm Agreements

A  substantial  portion  of  our  transportation  and  storage  capacity  is  contracted  for  under  firm  agreements.  For  the  year  ended  December  31,  2020,
approximately 90% of our revenues were derived from capacity reservation fees under firm contracts. The table below shows a rollforward of operating revenues
under committed firm agreements in place as of December 31, 2019, to December 31, 2020, including agreements for transportation, storage and other services,
over the remaining term of those agreements (in millions):

(1) As of December 31, 2019, we expected our 2020 revenues from fixed fees under firm agreements to be approximately $1,065.0 million, including
agreements for transportation, storage and other services. Our actual 2020 revenues recognized from fixed fees under firm agreements were $1,155.5
million,  an  increase  of  $90.5  million  resulting  primarily  from  contract  renewals  that  occurred  in  2020  and  the  receipt  of  proceeds  related  to  a
customer bankruptcy, as discussed in Note 5 in Part II, Item 8. of this Annual Report on Form 10-K.

During 2020, we entered into approximately $1.3 billion of new firm agreements, of which approximately 55% were from new growth projects executed
in 2020, but will not be placed into commercial service until 2024 or later years. As of December 31, 2020, our top ten customers holding firm capacity under firm
agreements comprised approximately 40% of our total projected operating revenues. Additionally, the credit profile associated with our customers comprising the
total projected operating revenues under firm agreements as of December 31, 2020, was 75% rated as investment grade, 4% rated as non-investment grade and
21% not rated. Note 3 in Part II, Item 8. of this Annual Report on Form 10-K contains more information regarding the revenues we expect to earn from fixed fees
under committed firm agreements.

20

    
Contract Renewals

Each year a portion of our firm transportation and storage agreements expire. The rates we are able to charge customers are heavily influenced by market
trends  (both short  and longer  term),  including  the  available  supply,  geographical  location  of  natural  gas  production,  the competition  between  producing  basins,
competition with other pipelines for supply and markets, the demand for gas by end-users such as power plants, petrochemical facilities and LNG export facilities
and the price differentials between the gas supplies and the market demand for the gas (basis differentials). Our storage rates are additionally impacted by natural
gas price differentials between time periods, such as winter to summer (time period price spreads), and the volatility in time period price spreads. Demand for firm
service is primarily based on market conditions which can vary across our pipeline systems. While we did not see a decrease in the demand for our transportation
services as a result of the COVID-19 pandemic or the volatility in energy prices during 2020, if these conditions were to remain for an extended period of time or
worsen, we could see a decline in the demand for our services. We focus our marketing efforts on enhancing the value of the capacity that is up for renewal and
work with customers to match gas supplies from various basins to new and existing customers and markets, including aggregating supplies at key locations along
our pipelines to provide end-use customers with attractive and diverse supply options. If the market perceives the value of our available capacity to be lower than
our long-term view of the capacity, we may seek to shorten contract terms until market perception improves. 

Over the past several years, as a result of market conditions, we have renewed some expiring contracts at lower rates or for shorter terms than in the past.
In addition to normal contract expirations, in the 2018 to 2020 timeframe, transportation agreements associated with our significant pipeline expansion projects that
were  placed  into  service  in  the  2007-2009  timeframe,  have  expired.  A  substantial  portion  of  the  capacity  associated  with  the  pipeline  expansion  projects  was
renewed or the contracts were restructured, usually at lower rates or lower volumes, which has negatively impacted our operating revenues. The last of the contract
expirations  associated  with  the  2007-2009  pipeline  expansion  projects  have  occurred  and  the  associated  impacts  on  operating  revenues  have  been,  and  will
continue to be, realized. Historically, we had delivered the majority of production volumes from these pipeline expansion projects to other pipelines. Over the past
several years, we have focused on diversifying our deliveries to end-use markets through utilizing available capacity from contract expirations and the capacity
created from our growth projects. We have diversified our deliveries such that almost 75% of our projected future firm reservation revenues, from firm agreements
in place as of December 31, 2020, are for deliveries to end-use customers.
Pipeline System Maintenance

We  incur  substantial  costs  for  ongoing  maintenance  of  our  pipeline  systems  and  related  facilities,  including  those  incurred  for  pipeline  integrity
management activities, equipment overhauls, general upkeep and repairs. These costs are not dependent on the amount of revenues earned from our transportation
services.  PHMSA  has  developed  regulations  that  require  transportation  pipeline  operators  to  implement  integrity  management  programs  to  comprehensively
evaluate certain areas along pipelines and take additional measures to protect pipeline segments located in highly populated areas. These regulations have resulted
in an overall increase in our ongoing maintenance costs, including maintenance capital and maintenance expense. In 2019, PHMSA issued the first part of its gas
Mega Rule, which became effective on July 1, 2020. This regulation imposed numerous requirements, including MAOP reconfirmation through re-verification of
all  historical  records  for  pipelines  in  service,  which  re-certification  process  may  require  natural  gas  pipelines  installed  before  1970  (previously  excluded  from
certain pressure testing obligations) to be pressure tested, the periodic assessment of additional pipeline mileage outside of HCAs (in MCAs as well as Class 3 and
Class 4 areas), the reporting of exceedances of MAOP and the consideration of seismicity as a risk factor in integrity management. The remaining rulemakings
comprising  the  gas  Mega  Rule  have  not  been  published  yet  and  we  cannot  predict  when  they  will  be  finalized;  however,  they  are  expected  to  include  revised
pipeline  repair  criteria  as well  as more  stringent  corrosion  control  requirements.  It is expected  that  these  new rules  will cause  us to incur  increased  capital  and
operating costs, experience operational delays and result in potential adverse impacts to our ability to reliably serve our customers. See Part I, Item 1. Business and
Item 1A. Risk Factors of this Annual Report on Form 10-K for further information.

Maintenance costs may be capitalized or expensed, depending on the nature of the activities. For any given reporting period, the mix of projects that we
undertake will affect the amounts we record as property, plant and equipment on our Consolidated Balance Sheets or recognize as expenses, which impacts our
earnings. In 2021, we expect to spend approximately $370.0 million to maintain our pipeline systems, of which approximately $150.0 million is expected to be
maintenance  capital.  In  2020,  we  spent  $361.1  million,  of  which  $148.8  million  was  recorded  as  maintenance  capital.  Refer  to  Capital Expenditures for  more
information regarding certain of our maintenance costs.

Results of Operations

Note  2  in  Part  II,  Item  8.  of  this  Annual  Report  on  Form  10-K  contains  a  summary  of  our  revenues  and  the  related  revenue  recognition  policies.  A
significant  portion  of  our  revenues  are  fee-based,  being  derived  from  capacity  reservation  charges  under  firm  agreements  with  customers,  which  do  not  vary
significantly  period  to  period,  but  are  impacted  by  longer-term  trends  in  our  business  such  as  lower  pricing  on  contract  renewals  and  other  factors  discussed
elsewhere in this MD&A. Our operating costs and expenses do not vary significantly based upon the amount of products transported, with the exception of costs
recorded in Fuel and transportation expense, which are netted with fuel retained on our Consolidated Statements of Income.

Please refer to the disclosures in this Item 7. of this Annual Report on Form 10-K of items that have impacted, or could impact in the future, our results of

operations.

2020 Compared with 2019

Our net income for the year ended December 31, 2020, decreased $5.2 million, or 2%, to $290.5 million compared to $295.7 million for the year ended
December 31, 2019, primarily due to the factors discussed below. Excluding the impacts from the 2020 and 2019 customer bankruptcies, as discussed in Note 5 in
Part II, Item 8. of this Annual Report on Form 10-K, our net income for the year ended December 31, 2020, would have decreased $13.8 million, or 5%, compared
to the comparative period.

Operating revenues for the year ended December 31, 2020, increased $2.4 million, or less than 1%, to $1,297.6 million, compared to $1,295.2 million for
the year ended December 31, 2019. Including the effect of the items in fuel and transportation expense, and excluding the impact from the customer bankruptcies
as discussed in Note 5 in Part II, Item 8. of this Annual Report on Form 10-K, operating revenues decreased $10.7 million, or 1%. The decrease was driven by
contract  expirations  that  were  recontracted  at  overall  lower  average  rates  as  discussed  above,  mostly  offset  by  revenues  from  our  recently  completed  growth
projects and higher storage and PAL revenues due to favorable market conditions.

Operating costs and expenses for the year ended December 31, 2020, increased $21.5 million, or 3%, to $843.0 million, compared to $821.5 million for
the year ended December 31, 2019. Excluding items offset with operating revenues, operating costs and expenses increased $17.0 million, or 2%, when compared
to 2019. The operating expense increase was primarily due to an increased asset base from recently completed growth projects and the expiration of property tax
abatements, partially offset by lower maintenance project spending and employee-related costs.

Total other deductions for the year ended December 31, 2020, decreased $13.7 million, or 8%, to $163.8 million compared to $177.5 million for 2019

primarily due to lower interest rates and higher allowance for funds used for construction.

Liquidity and Capital Resources

We are a partnership holding company and derive all of our operating cash flow from our operating subsidiaries. Our principal sources of liquidity include
cash generated from operating activities, our revolving credit facility and debt issuances. Our operating subsidiaries use cash from their respective operations to
fund  their  operating  activities  and  maintenance  capital  requirements,  service  their  indebtedness  and  make  advances  or  distributions  to  Boardwalk  Pipelines.
Boardwalk  Pipelines  uses  cash  provided  from  the  operating  subsidiaries  and,  as  needed,  borrowings  under  our  revolving  credit  facility  to  service  outstanding
indebtedness and make distributions or advances to us. At December 31, 2020, we had no guarantees of off-balance sheet debt or other similar commitments to
third parties, no debt obligations that contain provisions requiring accelerated payment of the related obligations in the event of specified levels of declines in credit
ratings and no other off-balance sheet arrangements.

At  December  31,  2020,  we  had  $2.9  million  of  cash  on  hand  and  more  than  $1.3  billion  of  available  borrowing  capacity  under  our  $1.475  billion
revolving credit facility. We anticipate that our existing capital resources, including our revolving credit facility and our cash flows from operating activities, will
be adequate to fund our operations and capital expenditures for 2021. We may seek to access the debt markets to fund some or all capital expenditures for growth
projects, acquisitions or for general partnership purposes. During 2020 we utilized the remaining capacity under our effective shelf registration statement, and we
plan to file with the SEC and expect to have declared effective in the first quarter 2021, a $1.0 billion shelf registration statement under which we may publicly
issue  debt  securities,  warrants  or  rights  from  time  to  time.  As  of  December  31, 2020,  we  have  $4.6 billion  of  contractual  cash  payment  obligations  under  firm
agreements, of which $4.4 billion represents principal and interest payments related to our long-term debt. Note 11 in Part II, Item 8. of this Annual Report

on  Form  10-K  contains  more  information  regarding  our  long-term  debt  and  financing  activities  and  Notes  4  and  5  contain  more  information  about  our  other
commitments.

Credit Ratings

Most of our senior unsecured debt is rated by independent credit rating agencies. The credit ratings affect our ability to access the public and private debt
markets, as well as the terms and the cost of our borrowings. Our ability to satisfy financing requirements or fund planned growth capital expenditures will depend
upon  our  future  operating  performance  and  our  ability  to  access  the  capital  markets,  which  are  affected  by  economic  factors  in  our  industry  as  well  as  other
financial and business factors, some of which are beyond our control. As of February 8, 2021, our credit ratings for our senior unsecured notes and that of our
operating subsidiaries having outstanding rated debt were as follows:            

Rating agency
Standard and Poor's
Moody's Investor Services
Fitch Ratings, Inc.

Subsidiaries)
BBB-/BBB-
Baa3/Baa2

Credit ratings reflect the view of a rating agency and are not a recommendation to buy, sell or hold any security, and may be revised or withdrawn at any
time by the rating agency if it determines that the facts and circumstances warrant such a change. Each credit agency's rating should be evaluated independently of
any other credit agency's rating.

Guarantee of Securities of Subsidiaries

During the second quarter 2020, we early adopted the SEC's Financial Disclosures about Guarantors and Issuers of Guaranteed Securities and Affiliates
Whose  Securities  Collateralize  a  Registrant's  Securities rules,  which  simplify  the  disclosure  requirements  under  Rule  3-10  of  Regulation  S-X  related  to  our
registered securities and allow for the simplified disclosure to be included within this MD&A. Accordingly, the required disclosures are provided below.

Our debt is primarily  issued  at Boardwalk Pipelines,  a wholly owned subsidiary of us, although we have historically  also issued debt at our operating
subsidiaries. As of December 31, 2020, all of the outstanding notes issued by Boardwalk Pipelines (Subsidiary Issuer) and the full amount of the revolving credit
facility, are guaranteed by us (Parent Guarantor). The purpose of the guarantees is to help simplify our reporting and capital structure.

We guarantee the amounts borrowed under the revolving credit facility, but those amounts are not subject to the reporting requirements of Rule 13-01 of
Regulation S-X. The below table identifies our principal amounts outstanding for the debt that is subject to the disclosure rules of Rule 13-01 of Regulation S-X (in
millions):

and in Note 11 in Part II, Item 8. of this Annual Report on Form 10-K.

(2) This represents principal amounts of outstanding debt at Gulf South and Texas Gas, excluding any borrowings under the revolving credit facility.

(3)  As  of  December  31,  2020  and  2019,  this  represents  the  amounts  related  to  a  finance  lease,  unamortized  debt  discount  and  issuance  costs  and

outstanding borrowings under the revolving credit facility guaranteed by Boardwalk Pipeline Partners.

The Guaranteed Notes are fully and unconditionally guaranteed by the Parent Guarantor on a senior unsecured basis. The guarantees of the Guaranteed
Notes rank equally with all of our existing and future senior debt, including our guarantee of indebtedness under our revolving credit facility. The guarantees will
be effectively subordinated in right of payment to all of our future secured debt to the extent of the value of the assets securing such debt. There are no restrictions
on the Subsidiary Issuer's ability to pay dividends or make loans to the Parent Guarantor. The guarantee obligations will be terminated with respect to any series of
notes if that series has been discharged or defeased.

Our operating assets, operating liabilities, operating revenues, expenses and other comprehensive income either exist at or are generated by our operating
subsidiaries. The Parent Guarantor and the Subsidiary Issuer have no material assets, liabilities or operations independent of their respective financing activities,
including the Guaranteed Notes and advances to and from each other and the operating subsidiaries as a result of the cash management program described in Note
2 of Part II, Item 8. of this Annual Report on Form 10-K, and their investments in the operating subsidiaries. For these reasons, we meet the criteria in Rule 13-01
of Regulation S-X to omit the summarized financial information from our disclosures.

Capital Expenditures

Maintenance  capital  expenditures  for  the  years  ended  December  31,  2020,  2019  and  2018  were  $148.8  million,  $138.7  million  and  $108.4  million.
Growth  capital  expenditures  were  $270.6  million,  $277.7  million  and  $359.8  million  for  the  years  ended  December  31,  2020,  2019  and  2018.  During  the  year
ended December 31, 2020, we purchased the remaining undivided interest in the Bistineau storage facility that we did not previously own for $18.8 million. In
2019 and 2018, we purchased $12.6 million and $18.5 million of natural gas to be used as base gas for our integrated natural gas pipeline system.

We expect  total capital  expenditures  to be approximately  $340.0 million  in 2021, including approximately  $150.0 million  for maintenance  capital  and

$190.0 million related to growth projects.

Critical Accounting Estimates and Policies

Our significant accounting policies are described in Note 2 in Part II, Item 8. of this Annual Report on Form 10-K. The preparation of these consolidated
financial statements in accordance with accounting principles generally accepted in the U.S. requires us to make estimates and judgments that affect the reported
amounts of assets, liabilities, revenues and expenses, and related disclosures of contingent assets and liabilities. Estimates are based on historical experience and on
various other assumptions that are believed to be reasonable under the circumstances. The result of this process forms the basis for making judgments about the
carrying  amount  of  assets  and  liabilities  that  are  not  readily  apparent  from  other  sources.  We  review  our  estimates  and  judgments  on  a  regular,  ongoing  basis.
Changes  in  facts  and  circumstances  may  result  in  revised  estimates  and  actual  results  may  differ  materially  from  those  estimates.  Any  effects  on  our  business,
financial position or results of operations resulting from revisions to these estimates are recorded in the periods in which the facts that give rise to the revisions
become known.

The  following  accounting  policies  and  estimates  are  considered  critical  due  to  the  potentially  material  impact  that  the  estimates,  judgments  and

uncertainties affecting the application of these policies might have on our reported financial information.

Goodwill

Goodwill represents the excess of the cost of an acquisition over the fair value of the net identifiable assets acquired and liabilities assumed. Goodwill is
tested for impairment at the reporting unit level at least annually or more frequently when events occur and circumstances change that would more likely than not
reduce the fair value of a reporting unit below its carrying amount. Accounting requirements provide that a reporting entity may perform an optional qualitative
assessment on an annual basis to determine whether events occurred or circumstances changed that would more likely than not reduce the fair value of a reporting
unit below its carrying amount. If an initial qualitative  assessment identifies that it is more likely than not that the fair value of a reporting unit is less than its
carrying  amount,  or  the  optional  qualitative  assessment  is  not  performed,  a  quantitative  analysis  is  performed.  The  quantitative  goodwill  impairment  test  is
performed by calculating the fair value of the reporting unit and comparing it to the reporting unit's carrying amount. If the fair value of a reporting unit exceeds its
carrying amount, goodwill of the reporting unit is not impaired. However, if the carrying amount of a reporting unit exceeds its fair value, an impairment loss is
recognized in an amount equal to that excess, limited to the total amount of goodwill recorded on the reporting unit.

As of November 30, 2020, our annual goodwill testing date, we performed a quantitative analysis on our two reporting units to measure whether the fair

value of either of our reporting units was less than their carrying amounts. The fair value

24

measurement of the reporting units was derived based on judgments and assumptions we believe market participants would use in assessing the fair value of the
reporting  units.  These  judgments  and  assumptions  included  the  valuation  premise,  use  of  a  discounted  cash  flow  model  to estimate  fair  value  under an  income
approach and inputs to the valuation model. The inputs included our five-year financial plan operating results, the long-term outlook for growth in natural gas and
NGLs demand, measures of the risk-free rate, equity premium and systematic risk used in the calculation of the applied discount rate under the capital asset pricing
model and views regarding future market conditions, among others. The reasonableness of fair value estimates under the income approach were supported by a
market approach under which we applied EBITDA multiples derived from publicly-available information to each reporting unit's EBITDA. The use of alternate
judgments and assumptions could substantially change the results of our goodwill impairment analysis, including the recognition of an impairment charge in our
Consolidated Financial Statements.

The results of the quantitative goodwill impairment test for 2020 and 2019 indicated that the fair value of our two reporting units exceeded their carrying
amounts  and  no  goodwill  impairment  charges  were  recognized.  The  estimated  fair  values  of  our  reporting  units  fluctuate  from  year  to  year,  and  in  2020,  the
estimated fair values of the reporting units exceeded their carrying amounts by amounts that were lower than indicated in 2019, with the cushion of a reporting unit
that had goodwill of $73.9 million being approximately 15%. Although the prospects for our reporting units remain positive, including their strong base operating
cash flows and the markets in which they operate, significant changes in future estimated operating revenues or cash flows, or any other changes to the inputs to
the valuation model, such as those previously discussed, could result in the recognition of future impairment charges.

Impairment of Long-Lived Assets (including Tangible and Definite-Lived Intangible Assets)

We evaluate whether the carrying amounts of our long-lived and intangible assets have been impaired when circumstances indicate the carrying amount
of those assets may not be recoverable. The carrying amount is not recoverable if it exceeds the undiscounted sum of cash flows expected to result from the use and
eventual disposition of the asset. If the carrying amount is not recoverable, an impairment loss is measured as the excess of the asset's carrying amount over its fair
value. For the years ended December 31, 2020, 2019 and 2018, we recognized immaterial amounts related to asset impairment charges.

Forward-Looking Statements

Certain statements contained in this Annual Report on Form 10-K, as well as some statements in periodic press releases and some oral statements made
by our officials and our subsidiaries during presentations about us, are “forward-looking.” Forward-looking statements include, without limitation, any statement
that  may  project,  indicate  or  imply  future  results,  events,  performance,  intentions  or  achievements,  and  may  contain  the  words  “expect,”  “intend,”  “plan,”
“anticipate,” “estimate,” “believe,” “will likely result” and similar expressions. In addition, any statement made by our management concerning future financial
performance (including future revenues, earnings or growth rates), ongoing business strategies or prospects and possible actions by us or our subsidiaries, are also
forward-looking statements.

Forward-looking statements are based on current expectations and projections about future events and their potential impact on us. While management
believes  that  these  forward-looking  statements  are  reasonable  as  and  when  made,  there  is  no  assurance  that  future  events  affecting  us  will  be  those  that  we
anticipate. All forward-looking statements are inherently subject to a variety of risks and uncertainties, many of which are beyond our control which could cause
actual results to differ materially from those anticipated or projected. These include, among others, risks and uncertainties related to the impacts of recent volatility
in energy prices and the COVID-19 pandemic, the impacts of changes to laws and regulations or the implementation thereof, the costs of maintaining and ensuring
the  integrity  and  reliability  of  our  pipeline  systems,  our  ability  to  maintain  or  replace  expiring  gas  transportation  and  storage  contracts,  our  ability  to  complete
projects that we have commenced or will commence, successful negotiation, consummation and completion of contemplated transactions, projects and agreements,
and our ability to contract and sell short-term capacity on our pipelines. Developments in any of these areas could cause our results to differ materially from results
that have been or may be anticipated or projected. Forward-looking statements speak only as of the date they are made and we expressly disclaim any obligation or
undertaking  to  update  these  statements  to  reflect  any  change  in  our  expectations  or  beliefs  or  any  change  in  events,  conditions  or  circumstances  on  which  any
forward-looking statement is based.

Refer to Part I, Item 1A. of this Annual Report on Form 10-K for additional risks and uncertainties regarding our forward-looking statements.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

Interest Rate Risk:

With the exception of our revolving credit facility, for which the interest rates are periodically reset, our debt has been issued at fixed rates. For fixed-rate
debt, changes in interest rates affect the fair value of the debt instruments but do not directly affect our earnings or cash flows. The following table presents market
risk associated with our fixed-rate, long-term debt at December 31 (in millions, except interest rates):

At December 31, 2020, we had $130.0 million of variable-rate debt outstanding at a weighted-average interest rate of 1.39%. A 1.00% increase in interest
rates would increase our cash payments for interest on our variable-rate debt by $1.3 million on an annualized basis. At December 31, 2019, we had $295.0 million
outstanding under variable-rate agreements at a weighted-average interest rate of 3.00%.

Commodity Risk:

Our pipelines do not take title to the natural gas and NGLs which they transport and store, therefore, they do not assume the related commodity price risk

associated with the products.

Credit Risk:

Our credit exposure generally relates to receivables for services provided, as well as volumes owed by customers for imbalances or gas lent by us to them,
generally  under  PAL and certain  firm  services.  Natural  gas price  volatility  can  materially  increase  credit  risk related  to gas loaned  to customers.  We  also have
credit risk related to customers supporting some of our growth projects. If any significant customer of ours should have credit or financial problems resulting in a
delay or failure to pay for services provided by us or repay gas they owe to us, this could have a material adverse effect on our business, financial condition, results
of operations or cash flows.

As of December 31, 2020, the amount of gas owed to our operating subsidiaries due to gas imbalances and gas loaned under PAL and certain firm service
agreements was approximately 11.2 trillion British thermal units (TBtu). Assuming an average market price during December 2020 of $2.45 per million British
thermal  unit  (MMBtu),  the  market  value  of  that  gas  was  approximately  $27.4  million.  As  of  December  31,  2019,  the  amount  of  gas  owed  to  our  operating
subsidiaries due to gas imbalances and gas loaned under PAL and certain firm service agreements was approximately  12.8 TBtu. Assuming an average market
price during December 2019 of $2.08 per MMBtu, the market value of that gas at December 31, 2019, was approximately $26.6 million. As of December 31, 2020
and 2019, there were no outstanding NGL imbalances owed to our operating subsidiaries.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors of Boardwalk GP, LLC and the Partners of Boardwalk Pipeline Partners, LP

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Boardwalk Pipeline Partners, LP and subsidiaries (the "Company") as of December 31,
2020 and 2019, the related consolidated statements of income, comprehensive income, cash flows and changes in partners’ capital, for each of the three years in the
period  ended  December  31,  2020,  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 Company as of December 31, 2020 and 2019, and the results of its operations and its cash flows for each
of the three years in the period ended December 31, 2020, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial
statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and
are  required  to  be  independent  with  respect  to  the  Company  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. The Company is not required to have, nor were
we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control
over  financial  reporting  but  not  for  the  purpose  of  expressing  an  opinion  on  the  effectiveness  of  the  Company’s  internal  control  over  financial  reporting.
Accordingly, we express no such opinion.

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.

Critical Audit Matter

The  critical  audit  matter  communicated  below  is  a  matter  arising  from  the  current-period  audit  of  the  financial  statements  that  was  communicated  or
required to be communicated to the audit committee and that (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our
especially  challenging,  subjective,  or  complex  judgments.  The  communication  of  critical  audit  matters  does  not  alter  in  any  way  our  opinion  on  the  financial
statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the
accounts or disclosures to which it relates.

Goodwill – Refer to Notes 2 and 8 to the financial statements

Critical Audit Matter Description

The Company’s evaluation of goodwill for impairment involves a quantitative analysis to measure whether the fair value of either of the reporting units is
less than their carrying amounts, including goodwill. If the carrying amount of a reporting unit exceeds its fair value, an impairment loss shall be recognized in an
amount equal to that excess, limited to the total amount of goodwill recorded on the reporting unit.

The fair value measurement of the reporting units is derived based on judgments and assumptions including the use of a discounted cash flow model to
estimate fair value and inputs to the valuation model. The inputs included the long-term outlook for growth in natural gas and NGLs demand, the applied discount
rate,  and  the  five-year  financial  plan  operating  results.  The  use  of  alternate  judgments  and  assumptions  could  substantially  change  the  results  of  the  goodwill
impairment analysis, including the recognition of an impairment charge in the Consolidated Statement of Income. The results of the

27

quantitative goodwill impairment test indicated that the fair value of the Company’s reporting units exceeded their carrying amounts and no goodwill impairment
charges were recognized.

We  identified  goodwill  for  Boardwalk  Pipeline  Partners,  LP  as  a  critical  audit  matter  because  of  the  significant  judgments  made  by  management  to
estimate the fair value of each reporting unit. This required a high degree of auditor judgment and an increased extent of effort, including the need to involve fair
value specialists, when performing audit procedures to evaluate the reasonableness of management’s judgments and assumptions related to the applied discount
rate, the long-term outlook for growth in natural gas and NGLs demand, and the Company’s future estimated operating revenues within the five-year financial plan
operating results.

How the Critical Audit Matter Was Addressed in the Audit

Our  audit  procedures  related  to  management’s  assumptions  underlying  the applied  discount  rates,  the  long-term  outlook  for  growth in  natural  gas  and

NGLs demand, and the Company’s future estimated operating revenues within the five-year financial plan operating results included the following, among others:

• We  tested  the  effectiveness  of  controls  over  management’s  goodwill  impairment  test,  including  controls  over  management’s  estimate  of  the  applied
discount rate, the long-term outlook for growth in natural gas and NGLs demand, and the future estimated operating revenues for each reporting unit.

• We evaluated management’s ability to accurately forecast future operating revenues by comparing actual results to management’s historical forecasts for

each reporting unit.

• We  evaluated  the  reasonableness  of  the  future  estimated  operating  revenues  within  the  five-year  financial  plan  operating  results  by  comparing  the

forecasts to:

– Historical operating revenues of the Company’s similar or existing contracts with customers and average annual growth rates.

–

Forecasted information in analyst and industry reports for the Company and certain of its peer companies.

• With the assistance of our fair value specialists, we evaluated the reasonableness of the applied discount rate, and the long-term outlook for growth in

natural gas and NGLs demand used as inputs to management’s goodwill impairment test for each reporting unit by:

– Comparing the Company’s estimate  of the long-term outlook for growth in natural gas and NGLs demand for each reporting  unit to industry

reports and other market data.

– Developing a range of independent estimates of the applied discount rate for each reporting unit and comparing those to the applied discount

rates selected by management for each reporting unit.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1: Corporate Structure

Boardwalk  Pipeline  Partners,  LP  (the  Company)  is  a  Delaware  limited  partnership  formed  in  2005  to  own  and  operate  the  business  conducted  by  its
primary subsidiary Boardwalk Pipelines, LP (Boardwalk Pipelines) and its operating subsidiaries, Gulf South Pipeline Company, LLC (Gulf South), Texas Gas
Transmission, LLC (Texas Gas), Boardwalk Louisiana Midstream, LLC (Louisiana Midstream), Boardwalk Petrochemical Pipeline, LLC and Boardwalk Texas
Intrastate, LLC (together, the operating subsidiaries), which consists of integrated natural gas and natural gas liquids and other hydrocarbons (herein referred to
together  as  NGLs)  pipeline  and  storage  systems.  All  of  the  Company's  operations  are  conducted  by  the  operating  subsidiaries.  Effective  January  1,  2020,  Gulf
South converted from a limited partnership to a limited liability company. Immediately subsequent to the conversion, Gulf Crossing Pipeline Company LLC was
merged into Gulf South.

As of December 31, 2020, Boardwalk Pipelines Holding Corp. (BPHC), a wholly-owned subsidiary of Loews Corporation (Loews), owned directly or

indirectly, 100% of the Company's capital.

Note 2: Basis of Presentation and Accounting Policies

Basis of Presentation

The accompanying consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in

the United States of America (U.S.) (GAAP).

Principles of Consolidation

The  consolidated  financial  statements  include  the  Company's  accounts  and  those  of  its  wholly-owned  subsidiaries  after  elimination  of  intercompany

transactions.

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,  liabilities,  revenues,  expenses  and  disclosure  of  contingent  assets  and  liabilities  and  the  fair  values  of  certain  items.  The  Company  bases  its
estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, which form the basis for making
judgments about the carrying amounts of assets and liabilities that are not readily apparent from other sources. Actual results could differ from such estimates.

Segment Information

The Company operates in one reportable segment - the operation of interstate natural gas and NGLs pipeline systems and integrated storage facilities.
This  segment  consists  of  interstate  natural  gas  pipeline  systems  which  are  located  in  the  Gulf  Coast  region,  Oklahoma,  Arkansas  and  the  Midwestern  states  of
Tennessee, Kentucky, Illinois, Indiana and Ohio and integrated natural gas storage facilities  located in Indiana, Kentucky, Louisiana and Mississippi, and NGL
pipelines and storage facilities in Louisiana and Texas.

Regulatory Accounting

Most of the Company's natural gas pipeline subsidiaries are regulated by the Federal Energy Regulatory Commission (FERC). When certain criteria are
met,  GAAP requires  that  certain  rate-regulated  entities  account  for  and  report  assets  and  liabilities  consistent  with  the  economic  effect  of  the  manner  in  which
independent  third-party  regulators  establish  rates  (regulatory  accounting).  This  basis  of  accounting  is  applicable  to  operations  of  the  Company's  Texas  Gas
subsidiary,  which  records  certain  costs  and  benefits  as  regulatory  assets  and  liabilities  in  order  to  provide  for  recovery  from  or  refunds  to  customers  in  future
periods, but is not applicable to the operations associated with the Fayetteville and Greenville Laterals due to rates charged under negotiated rate agreements and a
portion of Texas Gas' storage capacity due to the regulatory treatment associated with the rates charged for that capacity.

35

The  Company  applies  regulatory  accounting  for  its  fuel  trackers  on  Gulf  South,  under  which  the  value  of  fuel  received  from  customers  paying  the
maximum tariff rate and the related value of fuel used in transportation are recorded to a regulatory asset or liability depending on whether Gulf South uses more
fuel than it collects from customers or collects more fuel than it uses. Other than as described for Texas Gas and for the fuel trackers on Gulf South, regulatory
accounting is not applicable to the Company's other FERC-regulated operations.

The  Company  monitors  the  regulatory  and  competitive  environment  in  which  it  operates  to  determine  whether  its  regulatory  assets  continue  to  be
probable of recovery. If the Company determines that all or a portion of its regulatory assets no longer meets the criteria for recognition as regulatory assets, that
portion which is not recoverable will be written off, net of any regulatory liabilities.

Note 10 contains more information regarding the Company's regulatory assets and liabilities.

Fair Value Measurements

Fair value refers to an exit price that would be received to sell an asset or paid to transfer a liability in an orderly transaction in the principal market in
which the reporting entity transacts based on the assumptions market participants would use when pricing the asset or liability assuming its highest and best use. A
fair value hierarchy has been established that prioritizes the information used to develop those assumptions giving priority, from highest to lowest, to quoted prices
in active markets for identical assets and liabilities (Level 1); observable inputs not included in Level 1, for example, quoted prices for similar assets and liabilities
(Level 2); and unobservable data (Level 3), for example, a reporting entity's own internal data based on the best information available in the circumstances. The
Company uses fair value measurements to account for asset retirement obligations (ARO) and any impairment charges.

Notes 6 and 12 contain more information regarding fair value measurements.

Cash and Cash Equivalents

Cash  equivalents  are  highly  liquid  investments  with  an  original  maturity  of  three  months  or  less  and  are  stated  at  cost  plus  accrued  interest,  which

approximates fair value. The Company had no restricted cash at December 31, 2020 and 2019.

Cash Management

The operating subsidiaries participate in an intercompany cash management program, with those that are FERC-regulated participating to the extent they
are permitted  under FERC regulations.  Under the cash management  program, depending on whether a participating  subsidiary has short-term  cash surpluses or
cash requirements, Boardwalk Pipelines either provides cash to them or they provide cash to Boardwalk Pipelines. The transactions are represented by demand
notes  and are  stated  at  historical  carrying  amounts.  Interest  income  and  expense  are  recognized  on an  accrual  basis when collection  is  reasonably  assured.  The
interest rate on intercompany demand notes is London Interbank Offered Rate (LIBOR) plus 1.00% and is adjusted every three months.

Trade and Other Receivables

Trade and other receivables are stated at their historical carrying amount, net of allowances for doubtful accounts. The Company establishes an allowance
for doubtful accounts under an expected credit loss model based on historical credit loss experience and specific facts and circumstances. Uncollectible receivables
are  written  off  when  a  settlement  is  reached  for  an  amount  that  is  less  than  the  outstanding  historical  balance  or  a  receivable  amount  is  deemed  otherwise
unrealizable.

Gas Stored Underground and Gas Receivables and Payables

Certain of the Company's operating subsidiaries have underground gas in storage which is utilized for system management and operational balancing, as
well as for  services  including  firm  and interruptible  storage  associated  with  certain  no-notice  and parking  and lending  (PAL) services.  Gas stored  underground
includes the historical cost of natural gas volumes owned by the operating subsidiaries, at times reduced by certain operational encroachments upon that gas.

The operating subsidiaries provide storage services whereby they store natural gas or NGLs on behalf of customers and also periodically hold customer

gas under PAL services. Since the customers retain title to the gas held by the Company in

36

providing these services, the Company does not record the related gas on its Consolidated Balance Sheets. Certain of the Company's operating subsidiaries also
periodically lend gas and NGLs to customers.

In  the  course  of  providing  transportation  and  storage  services  to  customers,  the  operating  subsidiaries  may  receive  different  quantities  of  gas  from
shippers  and  operators  than  the  quantities  delivered  on  behalf  of  those  shippers  and  operators.  This  results  in  transportation  and  exchange  gas  receivables  and
payables, commonly known as imbalances, which are primarily settled in cash or the receipt or delivery of gas in the future. Settlement of imbalances requires
agreement between the pipelines and shippers or operators as to allocations of volumes to specific transportation contracts and timing of delivery of gas based on
operational conditions. The receivables and payables are valued at market price for operations where regulatory accounting is not applicable and are valued at the
historical value of gas in storage for operations where regulatory accounting is applicable.

Materials and Supplies

Materials  and  supplies  are  carried  at  average  cost  and  are  included  in  Other  Assets on  the  Consolidated  Balance  Sheets.  The  Company  expects  its
materials and supplies to be used for projects related to its property, plant and equipment (PPE) and for future growth projects. At December 31, 2020 and 2019,
the Company held approximately $25.5 million and $21.8 million of materials and supplies.

Property, Plant and Equipment and Repair and Maintenance Costs

PPE  is  recorded  at  its  original  cost  of  construction  or  fair  value  of  assets  purchased.  Construction  costs  and  expenditures  for  major  renewals  and
improvements which extend the lives of the respective assets are capitalized. Construction work in progress is included in the financial statements as a component
of PPE. Repair and maintenance costs are expensed as incurred.

Depreciation of PPE related to operations for which regulatory accounting does not apply is provided for using the straight-line method of depreciation
over the estimated useful lives of the assets, which range from 3 to 35 years. The ordinary sale or retirement of PPE for these assets could result in a gain or loss
being recorded in the income statement. Depreciation of PPE related to operations for which regulatory accounting is applicable is provided for primarily on the
straight-line method at FERC-prescribed rates over estimated useful lives of 5 to 62 years. Reflecting the application of composite depreciation, gains and losses
from the ordinary sale or retirement of PPE for these assets are not recognized in earnings and generally do not impact PPE, net.

Note 7 contains more information regarding the Company's PPE.

Goodwill and Intangible Assets

Goodwill represents the excess of the cost of an acquisition over the fair value of the net identifiable assets acquired and liabilities assumed. Goodwill is
tested for impairment at the reporting unit level at least annually, as of November 30, or more frequently when events occur and circumstances change that would
more likely than not reduce the fair value of a reporting unit below its carrying amount. A reporting entity may perform an optional qualitative assessment on an
annual basis to determine whether events occurred or circumstances changed that would more likely than not reduce the fair value of a reporting unit below its
carrying amount. If an initial qualitative assessment identifies that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, or
the optional qualitative assessment is not performed, a quantitative analysis is performed. The quantitative goodwill impairment test is performed by calculating the
fair value of the reporting unit and comparing it to the reporting unit's carrying amount. If the fair value of a reporting unit exceeds its carrying amount, goodwill of
the reporting unit is not impaired. However, if the carrying amount of a reporting unit exceeds its fair value, an impairment loss is recognized in an amount equal to
that excess, limited to the total amount of goodwill recorded on the reporting unit.

Intangible  assets  are  those  assets  which  provide  future  economic  benefit  but  have  no  physical  substance.  The  Company  recorded  intangible  assets  for
customer relationships obtained through its acquisitions. The customer relationships, which are included in Other Assets on the Consolidated Balance Sheets, have
a finite life and are being amortized over their estimated useful lives.

Note 8 contains more information regarding the Company's goodwill and intangible assets.

37

    
Impairment of Long-lived Assets (including Tangible and Definite-lived Intangible Assets)

The Company evaluates its long-lived and intangible assets for impairment when, in management's judgment, events or changes in circumstances indicate
that the carrying amount of such assets may not be recoverable. When such a determination has been made, management's estimate of undiscounted future cash
flows attributable to the remaining economic useful life of the asset (or asset group) is compared to the carrying amount of the asset (or asset group) to determine
whether an impairment has occurred. If an impairment of the carrying amount has occurred, the amount of impairment recognized in the financial statements is
determined by estimating the fair value of the assets (or asset group) and recording a loss to the extent that the carrying amount exceeds the estimated fair value.

Capitalized Interest and Allowance for Funds Used During Construction (AFUDC)

The  Company  records  capitalized  interest,  which  represents  the  cost  of  borrowed  funds  used  to  finance  construction  activities  for  operations  where
regulatory accounting is not applicable. The Company records AFUDC, which represents the cost of funds, including equity funds, applicable to regulated natural
gas transmission plant under construction as permitted by FERC regulatory practices, in connection with the Company's operations where regulatory accounting is
applicable. Capitalized interest and the allowance for borrowed funds used during construction are recognized as a reduction to Interest expense and the allowance
for  equity  funds  used  during  construction  is  included  in  Miscellaneous  other  income,  net within  the  Consolidated  Statements  of  Income.  The  following  table
summarizes capitalized interest and the allowance for borrowed funds and allowance for equity funds used during construction (in millions):

The Company is not a taxable entity for federal income tax purposes. As such, it does not directly pay federal income tax. The Company's taxable income
or loss, which may vary substantially from the net income or loss reported in the Consolidated Statements of Income, is includable in the federal income tax returns
of each of its partners. The aggregate difference in the basis of the Company's net assets for financial and income tax purposes is $4.4 billion. The subsidiaries of
the Company directly incur some income-based state taxes which are presented in Income taxes on the Consolidated Statements of Income.

Note 13 contains more information regarding the Company's income taxes.

Asset Retirement Obligations

The  accounting  requirements  for  existing  legal  obligations  associated  with  the  future  retirement  of  long-lived  assets  require  entities  to  record  the  fair
value of a liability for an ARO in the period during which the liability is incurred. The liability is initially recognized at fair value and is increased with the passage
of time as accretion expense is recorded, until the liability is ultimately settled. The accretion expense is included within Operation and maintenance costs within
the Consolidated Statements of Income. An amount corresponding to the amount of the initial liability is capitalized as part of the carrying amount of the related
long-lived asset and depreciated over the useful life of that asset.

Note 9 contains more information regarding the Company's ARO.

Environmental Liabilities

The Company records environmental liabilities based on management's estimates of the undiscounted future obligation for probable costs associated with
environmental assessment and remediation of operating sites. These estimates are based on evaluations and discussions with counsel and operating personnel and
the current known facts and circumstances related to these environmental matters.

Note 5 contains more information regarding the Company's environmental liabilities.

38

 
 
Defined Benefit Plans

The Company maintains  postretirement  benefit  plans for certain  employees.  The Company funds these  plans through periodic  contributions  which are
invested  until  the  benefits  are  paid  out  to  the  participants,  and  records  an  asset  or  liability  based  on  the  overfunded  or  underfunded  status  of  the  plan.  The  net
benefit costs of the plans are recorded in the Consolidated Statements of Income. Any deferred amounts related to unrecognized gains and losses or changes in
actuarial assumptions are recorded as either a regulatory asset or liability or recorded as a component of accumulated other comprehensive income (AOCI) until
those gains or losses are recognized in the Consolidated Statements of Income.

Note 12 contains more information regarding the Company's pension and postretirement benefit obligations.

Long-Term Compensation

Prior to the purchase of the Company's issued and outstanding publicly-owned common units by the Company's general partner in the third quarter 2018
(Purchase Transaction), the Company provided awards of phantom common units (Phantom Common Units) to certain employees under its Long-Term Incentive
Plan  (LTIP).  The  Company  also  provides  to  certain  employees  awards  of  long-term  cash  bonuses  (Long-Term  Cash  Bonuses)  under  the  Boardwalk  Pipeline
Partners Unit Appreciation Rights (UAR) and Cash Bonus Plan. Since 2018, the Company has not granted awards in the form of Phantom Common Units and as of
December 31, 2020, all remaining Phantom Common Units had vested and were paid. Beginning in 2019, the Company provided awards of performance awards
(Performance Awards) to certain of its employees under its 2018 Long-Term Incentive Plan (2018 LTIP). A Performance Award is a long-term incentive award
with a stated target amount which is payable in cash, after certain adjustments, upon vesting based on certain specified performance criteria being met.

The  Company  measures  the  cost  of  an  award  issued  in exchange  for  employee  services  based  on the  grant-date  fair  value  of  the  award in  the  case  of
Phantom  Common  Units,  or  the  stated  amount  in  the  case  of  Long-Term  Cash  Bonuses  or  the  stated  target  amount  for  Performance  Awards.  All  outstanding
awards are required to be settled in cash and are classified as a liability until settlement. Prior to the Purchase Transaction, unit-based compensation awards were
remeasured each reporting period until the final amount of awards were determined. Outstanding phantom units after the Purchase Transaction were fair valued at
the $12.06 cash purchase price per common unit of the Purchase Transaction plus amounts credited under the distribution equivalent rights (DERs). The related
compensation  expense,  less  forfeitures,  is  recognized  over  the  period  that  employees  are  required  to  provide  services  in  exchange  for  the  awards,  usually  the
vesting period.

Note 12 contains more information regarding the Company's long-term compensation.

Partner Capital Accounts

For  purposes  of  maintaining  capital  accounts  prior  to  the  Purchase  Transaction,  items  of  income  and  loss  of  the  Company  are  allocated  among  the

partners each period, or portion thereof, in accordance with the partnership agreement, based on their respective ownership interests.

Lease Accounting

Operating lease right-of-use assets and lease liabilities are recognized at the lease commencement date based on the present value of lease payments over
the lease term. The discount rate used to determine the commencement date present value of lease payments is typically the Company's secured borrowing rate, as
most of the Company's leases do not provide an implicit rate.

Revenue Recognition

Nature of Contracts

The Company primarily earns revenues from contracts with customers by providing transportation and storage services for natural gas and NGLs on a
firm  and  interruptible  basis.  The  Company  also  provides  interruptible  natural  gas  PAL  services.  The  Company's  customers  choose,  based  upon  their  particular
needs, the applicable mix of services depending upon availability of pipeline and storage capacity, the price of services and the volume and timing of customer
requirements. The maximum rates that may be charged by the majority of the Company's operating subsidiaries are established through the FERC's cost-based rate-
making process; however, rates actually charged by those operating subsidiaries may be less than those allowed by the FERC. Under the FERC regulations, certain
revenues that the Company's subsidiaries collect may be subject to possible refunds to customers. Accordingly, during a rate case, estimated refund liabilities are
recorded considering regulatory proceedings,

39

advice  of  counsel  and  estimated  risk-adjusted  total  exposure,  as  well  as  other  factors.  The  Company's  service  contracts  can  range  from  one  to  twenty  years
although the Company may enter into shorter- or longer-term contracts, and services are invoiced monthly with payment from the customer generally expected
within ten to thirty days, depending on the terms of the contract.

Firm Service Contracts: The Company offers firm services to its customers. The Company's customers can reserve a specific amount of pipeline capacity
at specified receipt and delivery points on the Company's pipeline system (transportation service) or can reserve a specific amount of storage capacity at specified
injection and withdrawal points at the Company's storage facilities (storage service). The Company accounts for firm services as a single promise to stand ready
each month of the contract term to provide the committed capacity for either transportation or storage services when needed by the customer, which represents a
series of distinct monthly services that are substantially the same with the same pattern of transfer to the customer. Although several activities may be required to
provide the firm service, the individual activities do not represent distinct performance obligations because all of the activities must be performed in combination
in order for the Company to provide the firm service.

The  transaction  price  for  firm  service  contracts  is  comprised  of  a  fixed  fee  based  on  the  quantity  of  capacity  reserved,  regardless  of  use  (capacity
reservation fee), plus variable fees in the form of a usage fee paid on the volume of commodity actually transported or injected and withdrawn from storage. Both
the fixed and usage fees are allocated to the single performance obligation of providing transportation or storage service and recognized over time based upon the
output measure of time as the Company completes its stand-ready obligation to provide contracted capacity and the customer receives and consumes the benefit of
the reserved capacity, which corresponds with the transfer of control to the customer. The fixed fee is recognized ratably over the contract term, representative of
the proportion of the committed stand-ready capacity obligation that has been fulfilled to date, and the usage fee is recognized upon satisfaction of each distinct
monthly performance obligation, consistent with the allocation objective and based upon the level of effort required to satisfy the stand-ready obligation in a given
month. Capacity reservation revenues derived from a firm service contract are generally consistent during the contract term, but can be higher in winter periods
than the rest of the year based upon seasonal rates.

Interruptible  Service  Contracts:  In  providing  interruptible  services  to  customers,  the  Company  agrees  to  transport  or  store  natural  gas  or  NGLs  for  a
customer  when  capacity  is  available.  The  Company  does  not  account  for  interruptible  services  with  a  customer  as  a  contract  until  the  customer  nominates  for
service and the Company accepts the nomination based upon available pipeline or storage capacity because there are no enforceable rights and obligations until
that time. The nomination and acceptance process is a daily activity and acceptance is granted based upon priority of service and availability of capacity. Upon
acceptance, the Company accounts for interruptible services similarly to its firm services.

The transaction price for interruptible service contracts is comprised of a variable fee in the form of a usage fee paid on the volume of commodity actually
transported or injected and withdrawn from storage. The usage fee is allocated to the single performance obligation of providing interruptible service. Interruptible
service revenues are generally recognized over time based on the output measure of volume transported or stored when services are rendered upon the successful
allocation of the services provided to the customer's account, which best depicts the transfer of control to the customer and satisfaction of the promised service.
Interruptible  services  are  recognized  in  the  month  services  are  provided  because  the  Company  has  a  right  to  consideration  from  customers  in  amounts  that
correspond directly to the value that the customer receives from the Company's performance. The rates charged may vary on a daily, monthly or seasonal basis.

Minimum Volume Commitment (MVC) Contracts: Certain of the Company's transportation or storage contracts require customers to transport or store a
minimum volume of commodity over a specified time period. If a customer fails to meet its MVC for the specified time period, the customer is obligated to pay a
contractually-determined deficiency fee based upon the shortfall between the actual volumes transported or stored and the MVC for that period. MVC contracts are
similar in nature to a firm service contract where the performance obligation is a stand-ready obligation that is a series of distinct services that are substantially the
same with the same pattern of transfer to the customer. The transaction price for an MVC is a fee for the volume of commodity actually transported or stored,
which is allocated to each distinct monthly performance obligation, consistent with the allocation objective and based upon the level of effort required to satisfy the
obligation of the transacted service in a given month. Revenues are generally recognized over time based on the output measure of volume transported or stored,
with the recognition of the deficiency fee in the period when it is known the customer cannot make up the deficient volume in the specified period.

Other: Periodically, the Company may enter into contracts with customers for the sale of natural gas or NGLs. The Company recognizes revenues for
these transactions at the point in time of the physical sale of the commodity, which corresponds with the transfer of control of the commodity to the customer and
the consideration is measured as the stated sales price in the contract.

Contract Balances

The Company records contract assets primarily related to performance obligations completed but not billed, or partially billed, as of the reporting date.

The Company records contract liabilities, or deferred income, when payment is received in advance of satisfying its performance obligations.

Note 3: Revenues

The Company operates in one reportable segment and contracts directly with end-use customers, including local distribution companies, electric power
generators, exporters of liquefied natural gas and industrial users, with producers and marketers of natural gas, and with interstate and intrastate pipelines, who, in
turn, provide transportation and storage services for end-users. The following table presents the Company's revenues disaggregated by type of service for the years
ended December 31, 2020, 2019 and 2018 (in millions):

Performance Obligations

The  following  table  includes  estimated  operating  revenues  expected  to  be  recognized  in  the  future  related  to  agreements  that  contain  performance
obligations that were unsatisfied as of December 31, 2020. The amounts presented primarily consist of fixed fees or MVCs which are typically recognized over
time as the performance obligation is satisfied, as in accordance with firm service contracts. Additionally, for the Company's customers that are charged maximum
tariff rates related to its FERC-regulated operating subsidiaries, the amounts below reflect the current tariff rate for such services for the term of the agreements;
however,  the  tariff  rates  may  be  subject  to  future  adjustment.  The  Company  has  elected  to  exclude  the  following  from  the  table:  (a)  unsatisfied  performance
obligations from usage fees associated with its firm services because of the stand-ready nature of such services; (b) consideration in contracts that are recognized in
revenue  as  invoiced,  such  as  for  interruptible  services;  and  (c)  consideration  that  was  received  prior  to  December  31,  2020,  that  will  be  recognized  in  future
periods, such as recorded in contract liabilities. The estimated revenues reflected in the table may include estimated revenues that are anticipated under executed
precedent transportation agreements for projects that are subject to regulatory approvals.

Note 4: Leases

The Company has various operating lease commitments extending through 2050, generally covering office space and equipment rentals, some of which
contain options to renew or extend the lease term. The Company also has a finance lease related to the lease of an office building in Owensboro, Kentucky, that has
a fifteen-year term with two twenty-year renewal options.

Operating lease right-of-use assets and lease liabilities are recognized at the lease commencement date based on the present value of lease payments over
the lease term. The discount rate used to determine the commencement date present value of lease payments is typically the Company's secured borrowing rate, as
most of the Company's leases do not provide an implicit rate. The components of lease cost were as follows (in millions):

Legal Proceedings and Settlements

The Company and its subsidiaries are parties to various legal actions arising in the normal course of business. Management believes the disposition of
these  outstanding  legal  actions,  including  the  legal  actions  identified  below,  will  not  have  a  material  impact  on  the  Company's  financial  condition,  results  of
operations or cash flows.

Mishal and Berger Litigation

On  May  25,  2018,  plaintiffs  Tsemach  Mishal  and  Paul  Berger  (on  behalf  of  themselves  and  the  purported  class,  Plaintiffs)  initiated  a  purported  class
action  in  the  Court  of  Chancery  of  the  State  of  Delaware  (the  Court)  against  the  following  defendants:  the  Company,  Boardwalk  GP,  LP  (Boardwalk  GP),
Boardwalk  GP,  LLC  and  BPHC  (together,  Defendants),  regarding  the  potential  exercise  by  Boardwalk  GP  of  its  right  to  purchase  the  issued  and  outstanding
common units of the Company not already owned by Boardwalk GP or its affiliates (Purchase Right).

On June 25, 2018, Plaintiffs and Defendants entered into a Stipulation and Agreement of Compromise and Settlement, subject to the approval of the Court
(the  Proposed  Settlement).  Under  the  terms  of  the  Proposed  Settlement,  the  lawsuit  would  be  dismissed,  and  related  claims  against  the  Defendants  would  be
released by the Plaintiffs, if BPHC, the sole member of the general partner of Boardwalk GP, elected to cause Boardwalk GP to exercise its Purchase Right for a
cash  purchase  price,  as  determined  by  the  Company's  Third  Amended  and  Restated  Agreement  of  Limited  Partnership,  as  amended  (the  Limited  Partnership
Agreement), and gave notice of such election as provided in the Limited Partnership Agreement within a period specified by the Proposed Settlement. On June 29,
2018, Boardwalk GP elected to exercise the Purchase Right and gave notice within the period specified by the Proposed Settlement. On July 18, 2018, Boardwalk
GP completed the purchase of the Company's common units pursuant to the Purchase Right.

On September 28, 2018, the Court denied approval of the Proposed Settlement. On February 11, 2019, a substitute verified class action complaint was
filed in this proceeding. The Defendants filed a motion to dismiss, which was heard by the Court in July 2019. In October 2019, the Court ruled on the motion and
granted a partial dismissal, with certain aspects of the case proceeding to trial. The case is set for trial in February 2021.

City of New Orleans Litigation

Gulf South, along with several other energy companies operating in Southern Louisiana, has been named as a defendant in a petition for damages and
injunctive relief in state district court for Orleans Parish, Louisiana, (Case No. 19-3466) by the City of New Orleans. The case was filed on March 29, 2019. The
lawsuit claims include, among other things, negligence, strict liability, nuisance and breach of contract, alleging that the defendants' drilling, dredging, pipeline and
industrial operations since the 1930s have caused increased storm surge risk, increased flood protection costs and unspecified damages to the City of New Orleans.
th
In October 2020, this case was stayed pending the outcome of an appeal to the 5  Circuit Court of Appeals in a similar case.

Letter of Credit Proceeds

In the fourth quarter 2020 and the second quarter 2019, two customers of Texas Gas declared bankruptcy and rejected the transportation agreements they
had with Texas Gas as part of the bankruptcy proceedings. As a result, Texas Gas pursued and received proceeds from existing letters of credit provided to Texas
Gas as credit support of $37.7 million from the 2020 bankruptcy and $27.7 million from the 2019 bankruptcy. In both cases, the bankruptcy courts approved the
rejection of the transportation agreements, which relieved Texas Gas from providing further transportation services to those customers and allowed Texas Gas to
remarket that capacity to other customers. Texas Gas first applied the proceeds from the letters of credit to any outstanding receivables related to the applicable
customers  and  then  recognized  as  transportation  revenues  the  remaining  $34.4  million  of  proceeds  in  December  2020  related  to  the  2020  bankruptcy  and
$26.2 million of proceeds in June 2019 related to the 2019 bankruptcy, which represent a portion of the future performance obligations that were eliminated under
the transportation agreements.    

Environmental and Safety Matters

The  Company's  operating  subsidiaries  are  subject  to  federal,  state  and  local  environmental  laws  and  regulations  in  connection  with  the  operation  and
remediation of various operating sites. As of December 31, 2020 and 2019, the Company had an accrued liability of approximately $4.2 million and $3.8 million
related to assessment and/or remediation costs associated

44

with  the  historical  use  of  polychlorinated  biphenyls,  petroleum  hydrocarbons  and  mercury.  The  liability  represents  management's  estimate  of  the  undiscounted
future  obligations  based  on  evaluations  and  discussions  with  counsel  and  operating  personnel  and  the  current  known  facts  and  circumstances  related  to  these
matters. The related expenditures are expected to occur over the next thirty years. As of December 31, 2020 and 2019, approximately $1.0 million was recorded in
Other current liabilities and approximately $3.2 million and $2.8 million were recorded in Other Liabilities and Deferred Credits.

Clean Air Act and Climate Change

The Company's pipelines and associated facilities are subject to the Clean Air Act (CAA) and comparable state laws and regulations, which regulate the
emission  of  air  pollutants  from  many  sources  and  impose  various  compliance  monitoring  and  reporting  requirements.  Under  the  CAA,  the  Company  may  be
required  to  obtain  pre-approval  for  the  construction  or  modification  of  certain  projects  or  facilities  expected  to  produce  or  significantly  increase  air  emissions,
obtain and strictly comply with stringent air permit requirements or utilize specific equipment or technologies to control emissions. The need to obtain permits has
the potential to delay the development or expansion of the Company's projects. Over the next several years, the Company may be required to incur certain capital
expenditures for air pollution control equipment or other air emissions related issues. For example, in 2015, the Environmental Protection Agency (EPA) issued a
final rule under the CAA, lowering the National Ambient Air Quality Standard (NAAQS) for ground-level ozone to 70 parts per billion under both the primary and
secondary standards to provide requisite protection of public health and welfare, respectively. Since that time, the EPA issued area designations with respect to
ground-level ozone, issued final requirements that apply to state, local and tribal air agencies for implementing the 2015 NAAQS for ground-level ozone and, on
December 31, 2020, published notice of a final action to retain the 2015 ozone NAAQS without revision on a going-forward basis. However, several groups have
filed litigation over this December 2020 final action, and the NAAQS may be subject to further revision under the Biden Administration. States are expected to
implement more stringent regulations that could apply to the Company's operations. Compliance with this final rule could, among other things, require installation
of  new  emission  controls  on  some  of  the  Company's  equipment,  result  in  longer  permitting  timelines  and  significantly  increase  its  capital  expenditures  and
operating costs. Additionally, the threat of climate change continues to attract considerable attention in the U.S. and in foreign countries. Numerous proposals have
been  made  and  could  continue  to  be  made  at  the  international,  national,  regional  and  state  levels  of  government  to  monitor  and  limit  existing  emissions  of
greenhouse gases (GHGs) as well as to restrict or eliminate  future emissions through such efforts as GHG cap and trade programs, carbon taxes, reporting and
tracking programs and restriction of emissions, such as methane emissions, from certain sources. The EPA has determined that GHG emissions endanger public
health and the environment and, as a result, has adopted regulations under the CAA related to GHG emissions.

Commitments for Construction

The Company's future capital commitments are comprised of binding commitments under purchase orders for materials ordered but not received and firm
commitments under binding construction service agreements. The commitments as of December 31, 2020, were approximately $128.4 million, all of which are
expected to be settled within the next twelve months.

Pipeline Capacity Agreements

The Company's operating subsidiaries have entered into pipeline capacity agreements with third-party pipelines that allow the operating subsidiaries to
transport  gas  to  off-system  markets  on  behalf  of  customers.  The  Company  incurred  expenses  of  $4.2  million,  $3.8  million  and  $4.6  million  related  to  pipeline
capacity agreements for the years ended December 31, 2020, 2019 and 2018. The future commitments related to pipeline capacity agreements as of December 31,
2020, were $5.5 million in 2021 and $2.7 million in 2022, with no future commitments after 2022.

Note 6: Other Comprehensive Income and Fair Value Measurements

Other Comprehensive Income

The Company estimates that approximately  $0.9 million of net losses reported in AOCI as of December 31, 2020, are expected to be reclassified  into
earnings within the next twelve months related to cash flow hedges. The amounts related to cash flow hedges are from treasury rate locks used in hedging interest
payments associated with debt offerings that were settled in previous periods and are being amortized to earnings over the terms of the related interest payments,
generally the terms of the related debt.

45

Financial Assets and Liabilities

As of  December  31, 2020 and  2019,  the  Company  had  no  assets  and  liabilities  which  were  recorded  at  fair  value  on a  recurring  basis.  The  following

methods and assumptions were used in estimating the fair value amounts included in the disclosures for financial assets and liabilities:

Cash and Cash Equivalents: For cash and short-term financial assets, the carrying amount is a reasonable estimate of fair value due to the short maturity

of those instruments.

Long-Term Debt: The estimated fair value of the Company's publicly traded debt is based on quoted market prices at December 31, 2020 and 2019. The
fair  market value of the debt that is not publicly traded  is based on market  prices of similar  debt at December  31, 2020 and 2019. The carrying  amount of the
Company's variable-rate debt at December 31, 2020 and 2019, approximated fair value because the instruments bear a floating market-based interest rate.

The carrying amounts and estimated fair values of the Company's financial assets and liabilities which were not recorded at fair value on the Consolidated

Balance Sheets as of December 31, 2020 and 2019, were as follows (in millions):

The non-depreciable assets were not included in the calculation of the weighted-average useful lives. 

The Company holds undivided interests in certain assets, including the Mobile Bay Pipeline of which the Company owns 64% and offshore and other
assets, comprised of pipeline and gathering assets in which the Company holds various ownership interests. In addition, the Company owns 83% of two ethylene
wells and supporting surface facilities in Choctaw, Louisiana, and certain ethylene and propylene pipelines connecting Louisiana Midstream's storage facilities in
Choctaw to chemical manufacturing plants in Geismar, Louisiana.

The  proportionate  share  of  investment  associated  with  these  interests  has  been  recorded  as  PPE  on  the  Consolidated  Balance  Sheets.  The  Company

Note 8: Goodwill and Intangible Assets

Goodwill

As of December 31, 2020 and 2019, the Company had recorded on its Consolidated Balance Sheets $237.4 million of goodwill. The Company performed
its  annual  goodwill  impairment  test  for  its  two  reporting  units  as  of  November  30,  2020  and  2019.  The  results  of  the  quantitative  goodwill  impairment  test
indicated that the fair value of the Company's reporting units exceeded their carrying amounts and no impairment charges related to goodwill were recorded for
any  of  the  Company's  reporting  units  during  2020,  2019  or  2018.  The  fair  value  measurement  of  the  reporting  units  was  derived  based  on  judgments  and
assumptions the Company believes market participants would use in assessing the fair value of the reporting units. These judgments and assumptions included the
valuation premise, use of a discounted cash flow model to estimate fair value under an income approach and inputs to the valuation model. The inputs included the
Company’s five-year  financial  plan operating results,  the long-term outlook for growth in natural  gas and NGLs demand, measures of the risk-free  rate, equity
premium and systematic risk used in the calculation of the applied discount rate under the capital asset pricing model and views regarding future market conditions,
among  others.  The  reasonableness  of  fair  value  estimates  under  the  income  approach  were  supported  by  a  market  approach  under  which  the  Company  applied
EBITDA multiples derived from publicly-available information to each reporting unit's EBITDA.

Note 9: Asset Retirement Obligations

The Company has identified and recorded legal obligations associated with the abandonment of certain pipeline and storage assets, brine ponds, offshore
facilities  and  the  abatement  of  asbestos  consisting  of  removal,  transportation  and  disposal  when  removed  from  certain  compressor  stations  and  meter  station
buildings.  Legal  obligations  exist  for  the  main  pipeline  and  certain  other  Company  assets;  however,  the  fair  value  of  these  obligations  cannot  be  determined
because  the  lives  of  the  assets  are  indefinite.  As  a  result,  cash  flows  associated  with  retirement  of  the  assets  cannot  be  estimated  with  the  degree  of  accuracy
necessary to establish a liability for the obligations.

For the Company's operations where regulatory accounting is applicable, depreciation rates for PPE are comprised of two components. One component is
based on economic service life (capital recovery) and the other is based on estimated costs of removal (as a component of negative salvage) which is collected in
rates and does not represent an existing legal obligation. The Company has reflected $81.6 million and $75.1 million as of December 31, 2020 and 2019, on the
Consolidated Balance Sheets as Provision for other asset retirement related to the estimated cost of removal collected in rates.

Note 10: Regulatory Assets and Liabilities

The amounts recorded as regulatory assets and liabilities on the Consolidated Balance Sheets as of December 31, 2020 and 2019, are summarized in the
table below. The table also includes amounts related to unamortized debt expense and unamortized discount on long-term debt, which while not regulatory assets
and liabilities, are a critical component of the embedded cost of debt financing utilized in Texas Gas' rate proceedings. The tax effect of the equity component of
AFUDC represents amounts recoverable from rate payers for the tax recorded in regulatory accounting. Certain amounts in the table are reflected as a negative, or
a reduction, to be consistent with the regulatory books of account. The period of recovery for the regulatory assets included in rates varies from one to eighteen
years.  The  remaining  period  of  recovery  for regulatory  assets  not yet  included  in rates  would be determined  in future  rate  proceedings.  None of  the regulatory
assets shown below were earning a return as of December 31, 2020 and 2019 (in millions):

(1) The  net  proceeds  of  this  offering  were  used  to  retire  the  Texas  Gas  2021  Notes  on  November  3,  2020,  to  fund  growth  capital  expenditures  and  for

general partnership purposes. Initially, the Company used the net proceeds to reduce outstanding borrowings under its revolving credit facility.

(2) The net proceeds of this offering were used to retire the outstanding $350.0 million aggregate principal amount of Boardwalk Pipelines 5.75% notes due
2019  at  maturity  and  for  general  partnership  purposes.  Initially,  the  Company  used  the  net  proceeds  to  reduce  outstanding  borrowings  under  its
revolving credit facility.

The Company's notes and debentures are redeemable, in whole or in part, at the Company's option at any time, at a redemption price equal to the greater
of 100% of the principal amount of the notes to be redeemed or a “make whole” redemption price based on the remaining scheduled payments of principal and
interest discounted to the date of redemption at a rate equal to the Treasury rate plus 20 to 50 basis points depending upon the particular issue of notes, plus accrued
and unpaid interest, if any. Other customary covenants apply, including those concerning events of default.

The indentures governing the notes and debentures have restrictive covenants which provide that, with certain exceptions, neither the Company nor any of
its subsidiaries may create, assume or suffer to exist any lien upon any property to secure any indebtedness unless the debentures and notes shall be equally and
ratably  secured.  All  of  the  Company's  debt  obligations  are  unsecured.  As  of  December  31,  2020,  Boardwalk  Pipelines  and  its  operating  subsidiaries  were  in
compliance with their debt covenants.

Revolving Credit Facility

The  Company  has  a  revolving  credit  facility  that  includes  Boardwalk  Pipelines,  Texas  Gas  and  Gulf  South  as  borrowers  (Borrowers).  Interest  is
determined, at the Company's election, by reference to (a) the base rate which is the highest of (1) the prime rate, (2) the federal funds rate plus 0.50% and (3) the
one month Eurodollar Rate plus 1.00%, plus an applicable margin, or (b) the one-month LIBOR plus an applicable margin. The applicable margin ranges from
0.00% to 0.75% for loans bearing interest based on the base rate and ranges from 1.00% to 1.75% for loans bearing interest based on the LIBOR rate, in each case
determined based on the individual Borrower's credit rating from time to time. The Third Amended and Restated Revolving Credit Agreement (amended credit
agreement) provides for a quarterly commitment fee charged on the average daily unused amount of the revolving credit facility ranging from 0.10% to 0.275%
which is determined based on the individual Borrower's credit rating from time to time. The revolving credit facility has a borrowing capacity of $1.475 billion
through May 26, 2022.

The revolving credit facility contains various restrictive covenants and other usual and customary terms and conditions, including restrictions regarding
the incurrence of additional debt, the sale of assets and sale-leaseback transactions. The financial covenants under the revolving credit facility require the Company
and  its  subsidiaries  to  maintain,  among  other  things,  a  ratio  of  total  consolidated  debt  to  consolidated  EBITDA  (as  defined  in  the  amended  credit  agreement)
measured  for  the  previous  twelve  months  of  not  more  than  5.0  to  1.0,  or  up  to  5.5  to  1.0  for  the  three  quarters  following  a  qualified  acquisition  or  series  of
acquisitions,  where  the  purchase  price  exceeds  $100.0  million  over  a  rolling  12-month  period.  The  Company  and  its  subsidiaries  were  in  compliance  with  all
covenant requirements under the revolving credit facility as of December 31, 2020.

Outstanding borrowings under the Company's revolving credit facility as of December 31, 2020 and 2019, were $130.0 million and $295.0 million, with
weighted-average borrowing rates of 1.39% and 3.00%. As of February 8, 2021, the Company had $170.0 million outstanding borrowings and approximately $1.3
billion of available borrowing capacity under the revolving credit facility.

Cash Distributions    

For each of the years ended December 31, 2020, 2019 and 2018, the Company paid cash distributions of $102.2 million to its partners as determined by

Boardwalk GP.

Note 12: Employee Benefits

Retirement Plans

Defined Benefit Retirement Plans (Retirement Plans)

Texas Gas employees hired prior to November 1, 2006, are covered under a non-contributory, defined benefit pension plan (Pension Plan). The Texas Gas
Supplemental  Retirement  Plan  (SRP)  provides  pension  benefits  for  the  portion  of  an  eligible  employee's  pension  benefit  under  the  Pension  Plan  that  becomes
subject to compensation limitations under the Internal Revenue Code. Collectively, the Company refers to the Pension Plan and the SRP as Retirement Plans. The
Company uses a measurement date of December 31 for its Retirement Plans.

As a result of the Texas Gas rate case settlement in 2006, the Company is required to fund the amount of annual net periodic pension cost associated with
the  Pension  Plan,  including  a  minimum  of  $3.0  million,  which  is  the  amount  included  in  rates.  In  2020  and  2019,  the  Company  funded  $3.6  million  and  $4.7
million to the Pension Plan and expects to fund an additional $4.5 million to the plan in 2021. In 2020 and 2019, there were no payments made to the SRP.

The  Company  recognizes  in  expense  each  year  the  actuarially  determined  amount  of  net  periodic  pension  cost  associated  with  the  Retirement  Plans,
including a minimum amount of $3.0 million related to its Pension Plan, in accordance with the 2006 rate case settlement. Texas Gas is permitted to seek future
rate  recovery  for  amounts  of  annual  Pension  Plan  costs  in  excess  of  $6.0  million  and  is  precluded  from  seeking  future  recovery  of  annual  Pension  Plan  costs
between $3.0 million and $6.0 million. As a result, the Company would recognize a regulatory asset for amounts of annual Pension Plan costs in excess of $6.0
million  and  would  reduce  its  regulatory  asset  to  the  extent  that  annual  Pension  Plan  costs  are  less  than  $3.0  million.  Annual  Pension  Plan  costs  between  $3.0
million and $6.0 million will be charged to expense.

52

Postretirement Benefits Other Than Pension (PBOP)

Texas Gas provides postretirement medical benefits and life insurance to retired employees who were employed full time, hired prior to January 1, 1996,
and have met certain other requirements. In each of 2020 and 2019, the Company contributed $0.1 million to the PBOP plan. The PBOP plan is in an overfunded
status;  therefore,  the  Company  does  not  expect  to  make  any  contributions  to  the  plan  in  2021.  The  Company  does  not  anticipate  that  any  plan  assets  will  be
returned to the Company during 2021. The Company uses a measurement date of December 31 for its PBOP plan.

(1) Pension expense was remeasured quarterly in 2020, 2019 and 2018. The quarterly remeasurements for each quarter in 2020, 2019 and 2018 were as
follows:  Quarter  1: 2.95%, 3.80% and 3.75%; Quarter  2: 2.20%, 3.25% and 3.85%; Quarter 3: 1.85%, 2.60% and 3.95%; and Quarter  4: 1.70%,
2.70% and 4.00%.

In determining the discount rate assumption, current market and liability information is utilized, including a discounted cash flow analysis of the pension
and postretirement  obligations.  In particular,  the basis  for  the  discount  rate  selection  was the  yield  on indices  of highly rated  fixed  income  debt  securities  with
durations comparable to that of the Company's plan liabilities. The yield curve was applied to expected future retirement plan payments to adjust the discount rate
to  reflect  the  cash  flow  characteristics  of  the  plans.  The  yield  curves  and  indices  evaluated  in  the  selection  of  the  discount  rate  are  comprised  of  high-quality
corporate bonds that are rated AA by an accepted rating agency.

The expected long-term rate of return for plan assets was determined based on widely-accepted capital market principles, long-term return analysis for
global fixed income and equity markets as well as the active total return oriented portfolio management style. Long-term trends are evaluated relative to market
factors such as inflation, interest rates and fiscal and monetary policies, in order to assess the capital market assumptions as applied to the plan. Consideration of
diversification needs and rebalancing is maintained.

Pension Plan and PBOP Asset Allocation and Investment Strategy

Pension Plan

The  Pension  Plan  investments  are  held  in  a  trust  account  and  consist  of  an  undivided  interest  in  an  investment  account  of  the  Loews  Corporation
Employees Retirement Trust (Master Trust), established by Loews and its participating subsidiaries. Use of the Master Trust permits the co-investing of trust assets
of the Pension Plan with the assets of the Loews Corporation Cash Balance Retirement Plan for investment and administrative purposes. Although assets of all
plans are co-invested in the Master Trust, the custodian maintains supporting records for the purpose of allocating the net gain or loss of the investment account to
the participating plans. The net investment income of the investment assets is allocated by the custodian to each participating plan based on the relationship of the
interest of each plan to the total of the interests of the participating plans. The Master Trust assets are measured at fair value. The fair value of the interest in the
assets of the Master Trust associated with the Pension Plan as of December 31, 2020 and 2019, was $102.7 million (or 43.9%) and $101.7 million (or 48.1%), of
the total Master Trust assets.

Equity securities are publicly traded securities which are valued using quoted market prices and are considered a Level 1 investment under the fair value
hierarchy. Short-term investments that are actively traded or have quoted prices, such as money market funds, are considered Level 1 investments. Fixed income
mutual funds include highly liquid government securities and exchange traded bonds, valued using quoted market prices, and are considered a Level 1 investment.
The limited partnership investments held within the Master Trust are recorded at fair value, which represents the Master Trust's shares of the net asset value of each
partnership, as determined by the general partner. The limited partnership and other invested assets consist primarily of hedge fund strategies that generate returns
through investing in marketable securities in the public fixed income and equity markets.

The PBOP plan assets are held in a trust and are measured at fair value. Short-term investments that are actively traded or have quoted prices, such as
money market or mutual funds, are considered Level 1 investments. Fixed income mutual funds are actively traded and valued using quoted market prices and are
considered Level 1 investments. Tax exempt securities, consisting of municipal securities, corporate and other taxable bonds and asset-backed securities are valued
using a methodology based on information generated by market transactions involving identical or comparable assets, a discounted cash flow methodology or a
combination  of  both  when  necessary.  Common  inputs  for  tax  exempt  securities  include  pricing  for  similar  securities,  marketplace  quotes,  benchmark  yields,
spreads  off benchmark  yields,  interest  rates  and  U.S. Treasury  or swap curves  and  other  pricing  models  utilizing  observable  inputs  and  are  considered  Level  2
investments. Specifically for asset-backed securities, key inputs include prepayment and default projections based on past performance of the underlying collateral
and current market data.

Pension Plan: The Company employs a total-return approach using a mix of equities and fixed income securities to maximize the long-term return on plan
assets for a prudent level of risk and generate cash flows adequate to meet plan requirements. The intent of this strategy is to minimize plan expenses by generating
investment returns that exceed the growth of the plan liabilities over the long run. Risk tolerance is established through careful consideration of the plan liabilities,
plan  funded  status  and  corporate  financial  conditions.  The  target  allocation  of  plan  assets  is  40%  to  60%  of  the  investment  portfolio  to  equity  and  limited
partnerships, with the remainder primarily invested in fixed income securities. The investment portfolio contains a diversified blend of fixed income, equity and
short-term securities. Alternative investments, including limited partnerships, have been used to enhance risk adjusted long-term returns while improving portfolio
diversification. At December 31, 2020, the pension trust had committed $2.3 million to future capital calls from various third party limited partnership investments
in exchange for an ownership interest in the related partnerships. Investment risk is monitored through annual liability measurements, periodic asset and liability
studies and quarterly investment portfolio reviews.

PBOP:  The  investment  strategy  for  the  PBOP  assets  is  to  reduce  the  volatility  of  plan  investments  while  protecting  the  initial  investment  given  the

overfunded status of the plan. At December 31, 2020 and 2019, all of the PBOP investments were in fixed income securities.

Defined Contribution Plan

Texas  Gas  employees  hired  on  or  after  November  1,  2006,  and  all  other  employees  of  the  Company  are  provided  retirement  benefits  under  a  defined
contribution plan, which also provides 401(k) plan benefits to its participants. Costs related to the Company's defined contribution plan were $11.9 million, $11.5
million and $11.1 million for the years ended December 31, 2020, 2019 and 2018.

Long-Term Incentive Compensation Plans

The  Company  grants  to  selected  employees  long-term  compensation  awards  under  the  LTIP  (prior  to  2019),  the  UAR  and  Cash  Bonus  Plan  (prior  to
2019) and the 2018 LTIP. These awards are intended to align the interests of the employees with those of the Company, encourage superior performance, attract
and  retain  employees  who  are  essential  for  the  Company's  growth  and  profitability  and  to  encourage  employees  to  devote  their  best  efforts  to  advancing  the
Company's business over both long and short-term time horizons.

LTIP

Beginning in 2019, as a result of the Purchase Transaction, no further grants of Phantom Common Units have been or will be made under the LTIP. As of
December 31, 2020, all of the remaining Phantom Common Units had vested and were paid. A summary of the status of the outstanding Phantom Common Units
under the Company's LTIP as of December 31, 2020 and 2019, and changes during the years ended December 31, 2020 and 2019, is presented below:

Outstanding  phantom  units  after  the  Purchase  Transaction  were  fair  valued  at  the  $12.06  cash  purchase  price  per  common  unit  of  the  Purchase
Transaction plus amounts credited under the DERs. The fair value of the awards were recognized ratably over the vesting period until settlement in accordance
with the treatment of awards classified as liabilities, and taking into account the payment elections selected by the grantees. The Company recorded $1.1 million,
$4.6 million and $7.3 million in Administrative and general expenses during  2020, 2019 and 2018 for the Phantom Common Unit awards. The total  estimated
remaining unrecognized compensation expense related to the Phantom Common Units outstanding at December 31, 2019, was $1.0 million.

UAR and Cash Bonus Plan

The UAR and Cash Bonus Plan provided for grants of UARs and Long-Term Cash Bonuses to select employees of the Company. Beginning in 2019, as a
result of the Purchase Transaction, no further grants of UARs or Long-Term Cash Bonuses have been or will be made under the UAR and Cash Bonus Plan. In
2018, the Company granted to certain employees $2.9 million of Long-Term Cash Bonuses, which vested and were paid to the holders in cash equal to the amount
of the grant in 2020. The Company recorded compensation expense of $0.3 million, $1.6 million and $2.2 million for the years ended December 31, 2020, 2019
and 2018, related to the Long-Term Cash Bonuses. As of December 31, 2020, all of the remaining Long-Term Cash Bonuses had vested and were paid. As of
December 31, 2019, the Company had $0.4 million remaining unrecognized compensation expense related to the Long-Term Cash Bonuses.

2018 LTIP

The 2018 LTIP provides for grants of Performance Awards to selected employees of the Company. A Performance Award is a long-term incentive award
with a stated target amount which is payable in cash, after adjustments, upon vesting based on certain specified performance criteria being met. The stated target
can  be  adjusted  based  on  the  level  of  achievement  of  the  performance  goals  for  the  vesting  period,  but  not  to  be  below  90%  or  to  exceed  110%  of  the  target
amount. In the case of retirement, any outstanding and unvested awards would become fully vested upon retirement and the Performance Awards will be paid at
the original vesting date. In 2020 and 2019, the Company granted to certain employees $12.2 million and $12.0 million of Performance Awards. The Company
recorded  compensation  expense  of  $10.9 million  and  $6.1  million  for  the  years  ended  December  31,  2020 and  2019, and  had  $7.0 million  and  $5.6 million  of
remaining unrecognized compensation expense related to the Performance Awards as of December 31, 2020 and 2019.

Note 13: Income Taxes

The Company's tax years 2017 through 2020 remain subject to examination by the Internal Revenue Service and the states in which it operates. There
were no differences between the provision at the statutory rate to the income tax provision at December 31, 2020, 2019 and 2018. As of December 31, 2020 and
2019, there were no significant deferred income tax assets or liabilities.

Note 14: Credit Risk

Major Customers

For the year ended December 31, 2020, the Company earned $132.5 million of operating revenues from one customer which represented approximately

10% of total operating revenues. For the years ended December 31, 2019 and 2018, no customer comprised 10% or more of the Company's operating revenues.

Gas Loaned to Customers

Natural gas price volatility can cause changes in credit risk related to gas and NGLs loaned to customers. As of December 31, 2020, the amount of gas
owed  to  the  Company's  operating  subsidiaries  due  to  gas  imbalances  and  gas  loaned  under  PAL  and  certain  firm  service  agreements  was  approximately  11.2
trillion  British  thermal  units  (TBtu).  Assuming  an  average  market  price  during  December  2020  of  $2.45  per  million  British  thermal  unit  (MMBtu),  the  market
value  of  that  gas  was  approximately  $27.4  million.  As  of  December  31,  2019,  the  amount  of  gas  owed  to  the  Company's  operating  subsidiaries  due  to  gas
imbalances and gas loaned under PAL and certain firm service agreements was approximately 12.8 TBtu. Assuming an average market price during December
2019 of $2.08 per MMBtu, the market value of that gas was approximately $26.6 million. As of December 31, 2020 and 2019, there were no outstanding NGL
imbalances owed to the Company's operating subsidiaries. If any significant customer should have credit or financial problems resulting in a delay or failure to
repay the gas owed to the operating subsidiaries, it could have a material adverse effect on the Company's financial condition, results of operations or cash flows.

Note 15: Related Party Transactions

Loews  provides  a  variety  of  corporate  services  to  the  Company  under  services  agreements,  including  information  technology,  tax,  risk  management,
internal audit and corporate development services and also charges the Company for allocated overheads. The Company incurred charges related to these services
of $5.7 million, $5.7 million and $6.2 million for the years ended December 31, 2020, 2019 and 2018, which were recorded in Administrative and general on the
Consolidated Statements of Income.

Total distributions paid to BPHC and Boardwalk GP were $102.2 million, $102.2 million and $77.2 million for each of the years ended December 31,

2020, 2019 and 2018.

Item 9A. Controls and Procedures

Disclosure Controls and Procedures

As required by Rule 13a-15(b) of the Exchange Act, we have evaluated, under the supervision and with the participation of our management, including
our principal executive officer and principal financial officer, the effectiveness of the design and operation of our disclosure controls and procedures (as defined in
Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this Annual Report on Form 10-K. Our disclosure controls and
procedures are designed to allow timely decisions regarding required disclosure and to provide reasonable assurance that the information required to be disclosed
by us in reports that we file under the Exchange Act is accumulated and communicated to our management, including our principal executive officer and principal
financial officer, as appropriate, and is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC. Based
upon the evaluation, our principal executive officer and principal financial officer have concluded that our disclosure controls and procedures were effective as of
December 31, 2020, at the reasonable assurance level.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred
during  the  quarter  ended  December  31,  2020,  that  have  materially  affected  or  that  are  reasonably  likely  to  materially  affect  our  internal  control  over  financial
reporting. 

Management's Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting for us. Our internal control system was

designed to provide reasonable assurance regarding the preparation and fair presentation of our published financial statements.

There are inherent limitations to the effectiveness of any control system, however well designed, including the possibility of human error and the possible
circumvention or overriding of controls. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls
must  be  considered  relative  to  their  costs.  Management  must  make  judgments  with  respect  to  the  relative  cost  and  expected  benefits  of  any  specific  control
measure. The design of a control system also is based in part upon assumptions and judgments made by management about the likelihood of future events, and
there can be no assurance that a control will be effective under all potential future conditions. As a result, even an effective system of internal control over financial
reporting  can  provide  no  more  than  reasonable  assurance  with  respect  to  the  fair  presentation  of  financial  statements  and  the  processes  under  which  they  were
prepared.

Our  management  assessed  the  effectiveness  of  our  internal  control  over  financial  reporting  as  of  December  31,  2020.  In  making  this  assessment,
management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control – Integrated Framework
(2013). Based on this assessment, our management believes that, as of December 31, 2020, our internal control over financial reporting was effective.

Auditor Engagement Pre-Approval Policy

We are a wholly-owned indirect subsidiary of Loews and the Loews Audit Committee has responsibility for the appointment, compensation and oversight
of  the  independent  external  audit  firm  retained  to  audit  our  financial  statements  and  the  audit  fee  negotiations  associated  with  their  retention.  To  assure  the
continued independence of our independent auditor, Deloitte & Touche, the Loews Audit Committee has adopted a policy requiring its pre-approval of all audit
and non-audit services performed for us and our subsidiaries by the independent auditor. Under this policy, the Loews Audit Committee annually pre-approved
certain  limited,  specified  recurring  services  which  may  be  provided  by  Deloitte  &  Touche,  subject  to  maximum  dollar  limitations.  All  other  engagements  for
services to be performed by Deloitte & Touche were specifically pre-approved by the Loews Audit Committee, or a designated committee member to whom this
authority had been delegated.

Under that policy, the Loews Audit Committee, or a designated member, pre-approved all engagements by us and our subsidiaries for services of Deloitte
&  Touche,  including  the  terms  and  fees  thereof,  and  the  Loews  Audit  Committee  concluded  that  all  such  engagements  were  compatible  with  the  continued
independence of Deloitte & Touche in serving as our independent auditor.
