“We continue to collaborate with our customers to deliver 

safe, reliable and more efficient ways to provide the 

services our customers value.”

President and Chief Executive Officer
Alan S. Armstrong

Dear Fellow Stockholders,

Our consistent, natural gas-focused
strategy delivered solid and
predictable growth in 2018, allowing 
us to once again post financial
metrics at the top end of our guidance
range. We achieved an all-time record
for Adjusted EBITDA, and $4.6 billion 
in asset sales over the past two and 
a half years has dramatically reduced 
commodity exposure and improved
leverage metrics for Williams. We 
also successfully executed the 
Williams Partners roll-up transaction, 
re-establishing the company as a
simplified C-Corp with investment-
grade credit.

I’m extremely pleased with our 
teams’ strong execution in 2018.
We continue to collaborate with our
customers to deliver safe, reliable
and more efficient ways to provide
the services our customers value.
This includes making great progress
in overcoming a highly challenging 
regulatory and permitting environment
to place critical new Transco projects, 
like Atlantic Sunrise, into full service.
Backed by long-term shipper
commitments, this historic project, 
brought into service in October, made 
the largest-volume pipeline system in
the country an even bigger network, 
adding an additional 1.7 billion 
cubic feet per day (approximately  
12 percent) to the Transco system.  
In 2019, Williams will benefit from 
a full year of revenue from Atlantic 

Sunrise — a project that is significant 
for our customers in Pennsylvania and 
our fast-growing demand markets.

Atlantic Sunrise has helped alleviate 
infrastructure bottlenecks and
extended the bi-directional flow
of the Transco system, directly 
connecting Marcellus gas supplies
with markets as far south as Alabama. 
Atlantic Sunrise’s impact on the 
debottlenecking of the Northeast
has helped spur the beginnings of 
what we believe will be accelerated
growth in that region for many years 
to come. In our Northeast G&P
segment, for example, fourth-quarter 
2018 gathering volumes increased by
13 percent over fourth-quarter 2017 
— increasing fourth-quarter 2018
Northeast G&P segment EBITDA by 
nearly 30 percent. We expect the 
increasing trend for gathered volumes 
to persist in 2019.

Our robust capital investment 
program continues to provide much 
higher than the industry average 
returns because our projects take 
advantage of our powerful network
of existing assets. These investments
further strengthen our competitive 
advantage and connect our 
customers to the best markets and 
long-term reliable supplies. 

We also exercised capital discipline in
2018 by funding much of these high

return projects via the sale of less 
strategic assets with lower growth. 
This includes opportunities like our
growth in the DJ Basin, which was 
funded through our exit from our 
legacy Four Corners Area position. 

The quality and predictability of
our cash flows, combined with the 
accelerating demand for natural gas, 
point to continued growth in 2019. 
In fact, after setting Transco delivery
records in 2018 and establishing 
the annual throughput record for 
Northwest Pipeline in 2018, we’ve 
already eclipsed Transco’s one-day 
and three-day delivery records in
2019. We’ve also placed the Gulf
Connector project into service to
serve two global LNG export facilities
and continue to explore value-
creating transactions to optimize 
our portfolio and strengthen our 
balance sheet.

We are committed to delivering
results in a way that also meets the 
needs of our stakeholders, and 
we remain engaged in the critical 
discussions on key issues shaping 
our industry. In 2018, we expanded 
our Environmental, Social and 
Governance (ESG) disclosures 
on our website and will further 
expand these disclosures in  
2019. We also strengthened our 
exceptional Board of Directors 
with two new appointments.

2018 Annual Report

The Williams Companies, Inc.

1

Our execution and results over the 
past year highlight why we are so 
bullish on the future. Williams has 
positioned itself as the leading 
natural gas infrastructure company 
in the United States, now operating 
as a simplified and focused C-Corp, 
with an attractive suite of assets, 
investment-grade credit ratings and
strong, steady, growing earnings 
and EBITDA. 

On behalf of the Board of Directors 
and our employees across the 
country, thank you for your continued 
trust in Williams.

Sincerely,

Alan S. Armstrong 
President and Chief Executive Officer

GENERAL

We are an energy infrastructure company focused on connecting North America’s significant hydrocarbon resource 

plays to markets for natural gas and NGLs. Our operations are located in the United States.

We were founded in 1908, originally incorporated under the laws of the state of Nevada in 1949 and reincorporated 
under the laws of the state of Delaware in 1987. Williams’ headquarters are located in Tulsa, Oklahoma, with other 
major  offices  in  Salt  Lake  City,  Utah;  Houston,  Texas;  and  Pittsburgh,  Pennsylvania. Our  telephone  number  is 
918-573-2000.

On August 10, 2018, we completed our merger with Williams Partners L.P. (WPZ), our previously consolidated 
master limited partnership, pursuant to which we acquired all of the approximately 256 million publicly held outstanding 
common units of WPZ in exchange for 382 million shares of our common stock in a noncash equity transaction.

WPZ MERGER

BUSINESS SEGMENTS

Prior to our merger with WPZ, we had one reportable segment, Williams Partners. Beginning in the third-quarter 
2018, consistent with the manner in which our chief operating decision maker evaluates performance and allocates 
resources, our operations are now presented within the following reportable segments: Northeast G&P, Atlantic-Gulf, 
and West. Prior period segment disclosures have been recast for the new segment presentation. Our reportable segments 
are comprised of the following businesses:

•  Northeast G&P is comprised of our midstream gathering and processing businesses in the Marcellus Shale 
region primarily in Pennsylvania, New York, and West Virginia and the Utica Shale region of eastern Ohio, 
as well as a 66 percent interest in Cardinal (a consolidated entity), a 62 percent equity-method investment in 
UEOM, a 69 percent equity-method investment in Laurel Mountain, a 58 percent equity-method investment 
in Caiman II, and Appalachia Midstream Services, LLC, which owns equity-method investments with an 
approximate average 66 percent interest in multiple gas gathering systems in the Marcellus Shale (Appalachia 
Midstream Investments).

4

•  Atlantic-Gulf is comprised of our interstate natural gas pipeline, Transco, and significant natural gas gathering 
and processing and crude oil production handling and transportation assets in the Gulf Coast region, including 
a 51 percent interest in Gulfstar One (a consolidated entity), which is a proprietary floating production system,  
and various petrochemical and feedstock pipelines in the Gulf Coast region, as well as a 50 percent equity-
method investment in Gulfstream, a 60 percent equity-method investment in Discovery, and a 41 percent 
interest in Constitution (a consolidated entity), which is developing a pipeline project (see Note 4 – Variable 
Interest Entities of Notes to Consolidated Financial Statements).

•  West is comprised of our interstate natural gas pipeline, Northwest Pipeline, and our gathering, processing,

We own a 69 percent interest in a joint venture, Laurel Mountain, that includes a 2,053-mile gathering system that 
we operate in western Pennsylvania with the capacity to gather 0.6 Bcf/d of natural gas. Laurel Mountain has a long-
term, dedicated, volumetric-based fee agreement, with exposure to natural gas prices, to gather the anchor customer’s 
production in the western Pennsylvania area of the Marcellus Shale.  

Caiman II

We own a 58 percent interest in Caiman II, which owns a 50 percent interest in Blue Racer, a joint project to own, 
operate, develop and acquire midstream assets in the Utica Shale and certain adjacent areas in the Marcellus Shale. 
Blue  Racer’s  assets  include  723  miles  of  gathering  pipelines,  and  the  Natrium  complex  in  Marshall  County, West 
Virginia, with a cryogenic processing capacity of 400 MMcf/d and fractionation capacity of approximately 134 Mbbls/
d. Blue Racer also owns the Berne complex in Monroe County, Ohio, with a cryogenic processing capacity of 400 
MMcf/d, and NGL and condensate pipelines connecting Natrium to Berne.  Blue Racer provides gathering, processing, 
and marketing service primarily under percentage of liquids and fixed fee agreements.

Utica East Ohio Midstream

We own a 62 percent interest in UEOM, which includes infrastructure for the gathering, processing, and fractionation 
of natural gas and NGLs in the Utica Shale play in eastern Ohio. Our partner operates a natural gas gathering pipeline,  
inlet compression, two processing plants with a total capacity of 800 MMcf/d, 36 Mbbls/d of condensate stabilization

capacity, a 135 Mbbls/d  NGL fractionation facility, approximately 950,000 barrels of NGL storage capacity, and other 
ancillary assets, including loading and terminal facilities. These assets earn a fixed fee that escalates annually within 
a specified range.  

Appalachia Midstream Investments 

Through our Appalachia Midstream Investments, we operate 100 percent of and own an approximate average 66 
percent interest in the Bradford Supply Hub gathering system and own an approximate average 68 percent interest in 
the Marcellus South gathering system, together which consist of approximately 1,028 miles of gathering pipeline in 
the Marcellus Shale region with the capacity to gather 4,623 MMcf/d of natural gas. The majority of our volumes in 
the region are gathered from northern Pennsylvania, southwestern Pennsylvania, and the northwestern panhandle of 
West Virginia  in  core  areas  of  the  Marcellus  Shale. We  operate  the  assets  under  long-term,  100  percent  fixed-fee 
gathering agreements that include significant acreage dedications and, in the Bradford Supply Hub, a cost of service 
mechanism.

During the first quarter of 2017, we exchanged all of our 50 percent interest in the Delaware basin gas gathering 
system, previously reported within the West segment, for an increased interest in the Bradford Supply Hub natural gas 
gathering  system  that  is  part  of  the Appalachia  Midstream  Investments  and  $155  million  in  cash.  Following  this 
exchange, we have an approximate average 66 percent interest in the Appalachia Midstream Investments. We continue 
to account for this investment under the equity-method due to the significant participatory rights of our partners such 
that we do not exercise control. (See Note 6 – Investing Activities of Notes to Consolidated Financial Statements.)

Aux Sable

We also own a 15 percent interest in Aux Sable and its Channahon, Illinois, gas processing and NGL fractionation 
facility near Chicago. The facility is capable of processing up to 2.1 Bcf/d of natural gas from the Alliance Pipeline 
system and fractionating approximately 132 Mbbls/d of extracted liquids into NGL products. Additionally, Aux Sable
owns an 80 MMcf/d gas conditioning plant and a 12-inch, 83-mile gas pipeline infrastructure in North Dakota that 
provides additional NGLs to Channahon from the Bakken Shale in the Williston basin.

the New York City metropolitan area. The system serves customers in Texas and 12 southeast and Atlantic seaboard 
states, including major metropolitan areas in Georgia, North Carolina, Washington, D.C., Maryland, New York, New 
Jersey, and Pennsylvania. 

At December 31, 2018, Transco’s system, which extends from Texas to New York, had a system-wide delivery 
capacity  totaling  approximately  16.7  MMdth  of  natural  gas  per  day.  During  2018,  Transco  completed  two  fully-
contracted expansions, which added more than 1.75 MMdth of firm transportation capacity per day to the existing 
pipeline system. Transco’s system includes 55 compressor stations, four underground storage fields, and one LNG 
storage facility. Compression facilities at sea level-rated capacity total approximately 2.2 million horsepower.

Transco has natural gas storage capacity in four underground storage fields located on or near its pipeline system 
or market areas and operates two of these storage fields. Transco also has storage capacity in an LNG storage facility 
that it owns and operates. The total usable gas storage capacity available to Transco and its customers in such underground 
storage fields and LNG storage facility and through storage service contracts is approximately 200 Bcf of natural gas.

our existing Delaware basin assets. This partnership consists of 725 miles of gas gathering pipelines, 260 MMcf/d of 
natural gas processing inlet capacity, and 75 miles of crude oil gathering pipelines.

Rocky Mountain Midstream

During the third quarter of 2018, our joint venture, RMM, purchased a natural gas and oil gathering and natural 
gas processing business in Colorado’s Denver-Julesburg basin. As of December 31, 2018, we own 50 percent of RMM. 
RMM consists of 60 MMcf/d of gas processing capacity, an approximate 105-mile natural gas gathering system, and 
an approximate 70-mile oil gathering system. There are two additional processing plants currently under construction 
that are expected to increase natural gas processing capacity to 480 MMcf/d by the end of 2019.

Delaware basin gas gathering system

We previously owned a non-operated 50 percent interest in the Delaware basin gas gathering system in the Permian 
basin, which was sold in February 2017.  The system was comprised of more than 450 miles of gathering pipeline, 
located in west Texas.

Overland Pass Pipeline

We also operate and own a 50 percent interest in OPPL. OPPL is capable of transporting 255 Mbbls/d and includes 
approximately 1,035 miles of NGL pipeline extending from Opal, Wyoming, to the Mid-Continent NGL market center 
near Conway, Kansas, along with extensions into the Piceance and Denver-Julesberg basins in Colorado and the Bakken 
Shale in the Williston basin in North Dakota. Our equity NGL volumes from two of our three Wyoming plants and our 
Willow Creek facility in Colorado are dedicated for transport on OPPL under a long-term transportation agreement. 
NGL volumes from our RMM equity-method investment are also expected to be transported on OPPL. 

Other

Other includes our previously owned operations, minor business activities that are not operating segments, as well 

as corporate operations.

Geismar Interest

In July 2017, we completed the sale of Williams Olefins, L.L.C, a wholly owned subsidiary which owned our 88.5 
percent undivided interest in the Geismar, Louisiana, olefins plant (Geismar Interest). Upon closing the sale, we entered 
into a long-term supply and transportation agreement with the purchaser to provide feedstock to the plant via our Bayou 
Ethane pipeline system.

Canadian Operations

We completed the sale of our Canadian operations in September 2016. This business included an oil sands offgas 
processing plant located near Fort McMurray, Alberta, and an NGL/olefin fractionation facility located at Redwater, 
Alberta, which is near Edmonton, Alberta, and the Boreal Pipeline which transported NGLs and associated olefins from 
the Fort McMurray plant to the Redwater fractionation facility. This business allowed us to extract, fractionate, treat, 
store,  terminal,  and  sell  the  ethane/ethylene,  propane,  propylene,  normal  butane,  iso-butane,  alky  feedstock,  and 
condensate recovered from a third-party oil sands bitumen upgrader.

Service Assets, Customers, and Contracts

Interstate Natural Gas Pipeline Assets

Our interstate natural gas pipelines are subject to regulation by the FERC and as such, our rates and charges for 
the transportation of natural gas in interstate commerce are subject to regulation. The rates are established through the 
FERC’s ratemaking process.    

12

Our interstate natural gas pipelines transport and store natural gas for a broad mix of customers, including local 
natural gas distribution companies, public utilities, municipalities, direct industrial users, electric power generators, 
and natural gas marketers and producers. We have firm transportation and storage contracts that are generally long-
term contracts with various expiration dates and account for the major portion of our regulated businesses. Additionally, 
we offer storage services and interruptible transportation services under shorter-term agreements.

On August 31, 2018, Transco filed a general rate case with the FERC for an overall increase in rates. In September 
2018, with the exception of certain rates that reflected a rate decrease, the FERC accepted and suspended our general 
rate filing to be effective March 1, 2019, subject to refund and the outcome of a hearing. The specific rates that reflected 
a rate decrease were accepted, without suspension, to be effective October 1, 2018, as requested by Transco, and will 
not be subject to refund. 

Gathering, Processing and Treating Assets

Our gathering systems receive natural gas from producers’ oil and natural gas wells and gather these volumes to 
gas processing, treating or redelivery facilities. Typically, natural gas, in its raw form, is not acceptable for transportation 
in major interstate natural gas pipelines or for commercial use as a fuel. Our treating facilities remove water vapor, 
carbon dioxide and other contaminants and collect condensate, but do not extract NGLs.  We are generally paid a fee 
based on the volume of natural gas gathered and/or treated, generally measured in the Btu heating value.

In addition, natural gas contains various amounts of NGLs, which generally have a higher value when separated 
from the natural gas stream. Our processing plants extract the NGLs in addition to removing water vapor, carbon 
dioxide, and other contaminants. NGL products include: 

•  Ethane, primarily used in the petrochemical industry as a feedstock for ethylene production, one of the basic 

building blocks for plastics;

•  Propane, used for heating, fuel and as a petrochemical feedstock in the production of ethylene and propylene, 
another building block for petrochemical-based products such as carpets, packing materials, and molded plastic 
parts;

•  Normal butane, isobutane, and natural gasoline, primarily used by the refining industry as blending stocks for 

motor gasoline or as a petrochemical feedstock.

Our gas processing services generate revenues primarily from the following types of contracts:

•  Fee-based: We are paid a fee based on the volume of natural gas processed, generally measured in the Btu 
heating value. Our customers are entitled to the NGLs produced in connection with this type of processing 
agreement. A  portion  of  our  fee-based  processing  revenue  includes  a  share  of  the  margins  on  the  NGLs 
produced. For the year ended December 31, 2018, 74 percent of our NGL production volumes were under 
fee-based contracts.

•  Noncash commodity-based:  We also process gas under two types of commodity-based contracts, keep-whole 
and percent-of-liquids, where we receive consideration for our services in the form of NGLs. Under these 
contracts, we retain some or all of the extracted NGLs as compensation for our services. For a keep-whole 
arrangement we replace the Btu content of the retained NGLs that were extracted during processing with 
natural gas purchases, also known as shrink replacement gas. For a percent-of-liquids arrangement, we deliver 
to customers an agreed-upon percentage of the extracted NGLs and retain the remainder. NGLs we retain in 
connection with these types of processing agreements are referred to as our equity NGL production. Under 
keep-whole agreements, we have commodity price exposure on the difference between NGL and natural gas 
prices. For the year ended December 31, 2018, 26 percent of our NGL production volumes were under noncash 
commodity-based contracts.

13

Our gathering and processing agreements have terms ranging from month-to-month to the life of the producing 
lease.  Generally,  our  gathering  and  processing  agreements  are  long-term  agreements.  Some  contracts  have  price 
escalators which annually increase our gathering rates. In addition, certain contracts include fee redetermination or cost 
of service mechanisms that are designed to support a return on invested capital and allow our gathering rates to be 
adjusted, subject to specified caps in certain cases, to account for variability in volume, capital expenditures, commodity 
price fluctuations, compression and other expenses. Certain of our gas gathering agreements include MVCs. If a customer 
under such an agreement fails to meet its MVC for a specified period, it is obligated to pay a contractually determined 
fee based upon the shortfall between the actual gathered or processed volumes and the MVC for the period contained 
in the contract. When we conclude it is probable that the customer will not exercise all or a portion of its remaining 
rights, we recognize revenue in an amount in proportion to the pattern of exercised rights within the respective MVC 
period.

Demand for gas gathering and processing services is dependent on producers’ drilling activities, which is impacted 
by the strength of the economy, natural gas prices, and the resulting demand for natural gas by manufacturing and 
industrial companies and consumers.  Our gas gathering and processing customers are generally natural gas producers 
who have proved and/or producing natural gas fields in the areas surrounding our infrastructure. During 2018, our 
facilities gathered and processed gas and crude oil for approximately 260 customers. Our top ten customers accounted 
for  approximately  70  percent  of  our  gathering  and  processing  fee  revenues  and  NGL  margins  from  our  noncash 
commodity-based agreements. 

Demand for our equity NGLs is affected by economic conditions and the resulting demand from industries using 
these commodities to produce petrochemical-based products such as plastics, carpets, packing materials, and blending 
stocks for motor gasoline and the demand from consumers using these commodities for heating and fuel.  NGL products 
are currently the preferred feedstock for ethylene and propylene production, which has shifted away from the more 
expensive crude-based feedstocks.

Key variables for our business will continue to be: 

•  Producer drilling activities impacting natural gas supplies supporting our gathering and processing volumes;

•  Prices impacting our commodity-based activities;

•  Retaining and attracting customers by continuing to provide reliable services;

•  Revenue growth associated with additional infrastructure either completed or currently under construction;

•  Disciplined growth in our service areas.

Crude Oil Transportation and Production Handling Assets

Our crude oil transportation revenues are typically volumetric-based fee arrangements. Crude oil marketing activity 
is now presented on a net basis within Product costs in the Consolidated Statement of Operations in 2018 in conjunction 
with the adoption of ASC 606. (See Note 1 – General, Description of Business, Basis of Presentation, and Summary 
of Significant Accounting Policies of Notes to Consolidated Financial Statements.) Revenue sources have historically 
included a combination of fixed-fee, volumetric-based fee, and cost reimbursement arrangements. Fixed fees associated 
with the resident production at our Devils Tower facility are recognized on a units-of-production basis. Fixed fees 
associated with the resident production at our Gulfstar One facility are recognized as the guaranteed capacity is made 
available. 

Additional Business Segment Information

We perform certain management, legal, financial, tax, consultation, information technology, administrative, and 

other services for our subsidiaries.

Our principal sources of cash are from dividends and advances from our subsidiaries, investments, payments by 
subsidiaries for services rendered, and, if needed, external financings, and net proceeds from asset sales. The terms of 

14

our credit agreement, which also govern certain subsidiaries’ borrowing arrangements, may limit the transfer of funds 
to us under certain conditions.

We believe that we have adequate sources and availability of raw materials and commodities for existing and 
anticipated business needs. Our interstate pipeline systems are all regulated in various ways resulting in the financial 
return on the investments made in the systems being limited to standards permitted by the regulatory agencies. Each 
of the pipeline systems has ongoing capital requirements for efficiency and mandatory improvements, with expansion 
opportunities also necessitating periodic capital outlays.

FERC

REGULATORY MATTERS 

Our gas pipeline interstate transmission and storage activities are subject to FERC regulation under the Natural 
Gas Act of 1938 (NGA) and under the Natural Gas Policy Act of 1978, and, as such, our rates and charges for the 
transportation of natural gas in interstate commerce, accounting, and the extension, enlargement, or abandonment of 
our jurisdictional facilities, among other things, are subject to regulation. Each of our gas pipeline companies holds 
certificates of public convenience and necessity issued by the FERC authorizing ownership and operation of all pipelines, 
facilities, and properties for which certificates are required under the NGA. FERC Standards of Conduct govern how 
our interstate pipelines communicate and do business with gas marketing employees. Among other things, the Standards 
of Conduct require that interstate gas pipelines not operate their systems to preferentially benefit gas marketing functions.

FERC regulation requires all terms and conditions of service, including the rates charged, to be filed with and 
approved by the FERC before any changes can go into effect. Our interstate gas pipeline companies establish rates 
through  the  FERC’s  ratemaking  process.  In  addition,  our  interstate  gas  pipelines  may  enter  into  negotiated  rate 
agreements where cost-based recourse rates are made available. Key determinants in the FERC ratemaking process 
include:

•  Costs of providing service, including depreciation expense;

•  Allowed rate of return, including the equity component of the capital structure and related income taxes;

•  Contract and volume throughput assumptions.

The allowed rate of return is determined in each rate case. Rate design and the allocation of costs between the 
reservation and commodity rates also impact profitability. As a result of these proceedings, certain revenues previously 
collected may be subject to refund.

We also own interests in and operate two offshore transmission pipelines that are regulated by the FERC because 
they are deemed to transport gas in interstate commerce. Black Marlin Pipeline Company provides transportation service 
for offshore Texas production in the High Island area and redelivers that gas to intrastate pipeline interconnects near 
Texas City. Discovery provides transportation service for offshore Louisiana production from the South Timbalier, 
Grand  Isle,  Ewing  Bank,  and  Green  Canyon  (deepwater)  areas  to  an  onshore  processing  facility  and  downstream 
interconnect points with major interstate pipelines. In addition, we own a 50 percent equity-method investment in and 
are the operator of OPPL, which is an interstate natural gas liquids pipeline regulated by the FERC pursuant to the 
Interstate Commerce Act. OPPL provides transportation service pursuant to tariffs filed with the FERC. We also own 
an ethane pipeline in West Virginia and Pennsylvania (Williams Ohio Valley Pipeline LLC) and an ethane pipeline in 
Texas and Louisiana (Williams Bayou Ethane Pipeline) each of which provides interstate service subject to FERC 
jurisdiction under the Interstate Commerce Act.

Pipeline Safety

Our gas pipelines are subject to the Natural Gas Pipeline Safety Act of 1968, as amended, the Pipeline Safety 
Improvement Act of 2002, the Pipeline Safety, Regulatory Certainty, and Jobs Creation Act of 2011 (Pipeline Safety 
Act),  and  the  Protecting  Our  Infrastructure  of  Pipelines  and  Enhancing  Safety Act  of  2016,  which  regulate  safety 
requirements in the design, construction, operation, and maintenance of interstate natural gas transmission facilities. 

15

The United States Department of Transportation Pipeline and Hazardous Materials Safety Administration (PHMSA) 
administers federal pipeline safety laws.

Federal pipeline safety laws authorize PHMSA to establish minimum safety standards for pipeline facilities and 
persons engaged in the transportation of gas or hazardous liquids by pipeline. These safety standards apply to the design, 
construction, testing, operation, and maintenance of gas and hazardous liquids pipeline facilities affecting interstate or 
foreign  commerce.  PHMSA  has  also  established  reporting  requirements  for  operators  of  gas  and  hazardous  liquid 
pipeline facilities, as well as provisions for establishing the qualification of pipeline personnel and requirements for 
managing the integrity of gas transmission and distribution lines and certain hazardous liquid pipelines. To ensure 
compliance  with  these  provisions,  PHMSA  performs  pipeline  safety  inspections  and  has  the  authority  to  initiate 
enforcement actions.

Federal pipeline safety regulations contain an exemption that applies to gathering lines in certain rural locations. 
A substantial portion of our gathering lines qualify for that exemption and are currently not regulated under federal 
law.

States are largely preempted by federal law from regulating pipeline safety for interstate pipelines but most are 
certified by PHMSA to assume responsibility for enforcing intrastate pipeline safety regulations and inspecting intrastate 
pipelines. In practice, because states can adopt stricter standards for intrastate pipelines than those imposed by the 
federal government for interstate lines, they vary considerably in their authority and capacity to address pipeline safety. 

Pipeline Integrity Regulations

We have an enterprise-wide Gas Integrity Management Plan that we believe meets the PHMSA final rule that was 
issued pursuant to the requirements of the Pipeline Safety Improvement Act of 2002. The rule requires gas pipeline 
operators to develop an integrity management program for gas transmission pipelines that could affect high-consequence 
areas in the event of pipeline failure. The integrity management program includes a baseline assessment plan along 
with periodic reassessments to be completed within required time frames. In meeting the integrity regulations, we have 
identified high-consequence areas and developed baseline assessment plans. Ongoing periodic reassessments and initial 
assessments of any new high-consequence areas have been completed. We estimate that the cost to be incurred in 2019
associated with this program to be approximately $86 million. Management considers costs associated with compliance 
with the rule to be prudent costs incurred in the ordinary course of business and, therefore, recoverable through Northwest 
Pipeline’s and Transco’s rates.

We have an enterprise-wide Liquid Integrity Management Plan that we believe meets the PHMSA final rule that 
was issued pursuant to the requirements of the Pipeline Safety Improvement Act of 2002.  The rule requires liquid 
pipeline operators to develop an integrity management program for liquid transmission pipelines that could affect high-
consequence areas in the event of pipeline failure. The integrity management program includes a baseline assessment 
plan along with periodic reassessments expected to be completed within required time frames.  In meeting the integrity 
regulations, we utilized government defined high-consequence areas and developed baseline assessment plans. We 
completed assessments within the required time frames. We estimate that the cost to be incurred in 2019 associated 
with this program will be approximately $3 million. Ongoing periodic reassessments and initial assessments of any 
new high-consequence areas are expected to be completed within the time frames required by the rule. Management 
considers the costs associated with compliance with the rule to be prudent costs incurred in the ordinary course of 
business.

State Gathering Regulations

Our onshore midstream gathering operations are subject to laws and regulations in the various states in which we 
operate. For example, the Texas Railroad Commission has the authority to regulate the terms of service for our intrastate 
natural gas gathering business in Texas. Although the applicable state regulations vary widely, they generally require 
that pipeline rates and practices be reasonable and nondiscriminatory, and may include provisions covering marketing, 
pricing, pollution, environment, and human health and safety. Some states, such as New York, have specific regulations 
pertaining to the design, construction, and operations of gathering lines within such state. 

16

Intrastate Liquids Pipelines in the Gulf Coast

Our intrastate liquids pipelines in the Gulf Coast are regulated by the Louisiana Public Service Commission, the 
Texas Railroad Commission, and various other state and federal agencies. These pipelines are also subject to the liquid 
pipeline safety and integrity regulations discussed above since both Louisiana and Texas have adopted the integrity 
management regulations defined in PHMSA.

OCSLA

Our offshore gas and liquids pipelines located on the outer continental shelf are subject to the Outer Continental 
Shelf Lands Act, which provides in part that outer continental shelf pipelines “must provide open and nondiscriminatory 
access to both owner and nonowner shippers.”

See  Part  II,  Item  8.  Financial  Statements  and  Supplementary  Data —  Note  18  –  Contingent  Liabilities  and 
Commitments of  Notes to Consolidated Financial Statements for further details on our regulatory matters. For additional 
information regarding regulatory matters, please also refer to Part 1, Item 1A. “Risk Factors” — “The operation of our 
businesses  might  be  adversely  affected  by  regulatory  proceedings,  changes  in  government  regulations  or  in  their 
interpretation or implementation, or the introduction of new laws or regulations applicable to our businesses or our 
customers,” and “The natural gas sales, transportation, and storage operations of our gas pipelines are subject to 
regulation by the FERC, which could have an adverse impact on their ability to establish transportation and storage 
rates that would allow them to recover the full cost of operating their respective pipelines, including a reasonable rate 
of return.”

ENVIRONMENTAL MATTERS 

Our operations are subject to federal environmental laws and regulations as well as the state, local, and tribal laws 
and regulations adopted by the jurisdictions in which we operate. We could incur liability to governments or third 
parties for any unlawful discharge of pollutants into the air, soil, or water, as well as liability for cleanup costs. Materials 
could be released into the environment in several ways including, but not limited to:

•  Leakage from gathering systems, underground gas storage caverns, pipelines, processing or treating facilities, 

transportation facilities, and storage tanks;

•  Damage to facilities resulting from accidents during normal operations;

•  Damages to onshore and offshore equipment and facilities resulting from storm events or natural disasters;

•  Blowouts, cratering, and explosions.

In addition, we may be liable for environmental damage caused by former owners or operators of our properties.

We believe compliance with current environmental laws and regulations will not have a material adverse effect 
on our capital expenditures, earnings, or current competitive position. However, environmental laws and regulations 
could affect our business in various ways from time to time, including incurring capital and maintenance expenditures, 
fines and penalties, and creating the need to seek relief from the FERC for rate increases to recover the costs of certain 
capital expenditures and operation and maintenance expenses.

For additional information regarding the potential impact of federal, state, tribal, or local regulatory measures on 
our business and specific environmental issues, please refer to Part 1, Item 1A. “Risk Factors” — “Our operations are 
subject to environmental laws and regulations, including laws and regulations relating to climate change and greenhouse 
gas emissions, which may expose us to significant costs, liabilities, and expenditures that could exceed our expectations,”
and  Part  II,  Item  7  “Management’s  Discussion  and Analysis  of  Financial  Condition  and  Results  of  Operations  — 
Environmental” and “Environmental Matters” in  Part II, Item 8. Financial Statements and Supplementary Data —

Gas Pipeline Business

COMPETITION

The market for supplying natural gas is highly competitive and new pipelines, storage facilities, and other related 
services are expanding to service the growing demand for natural gas. Additionally, pipeline capacity in many growing 
natural gas supply basins is constrained causing competition to increase among pipeline companies as they strive to 
connect those basins to major natural gas demand centers.  

In our business, we compete with major intrastate and interstate natural gas pipelines. In the last few years, local 
distribution  companies  have  also  started  entering  into  the  long-haul  transportation  business  through  joint  venture 
pipelines. The  principle  elements  of  competition  in  the  interstate  natural  gas  pipeline  business  are  based  on  rates, 
reliability, quality of customer service, diversity of supply, and proximity to customers and market hubs. 

Significant entrance barriers to build new pipelines exist, including federal and growing state regulations and public 
opposition against new pipeline builds, and these factors will continue to impact potential competition for the foreseeable 
future. However, we believe the position of our existing infrastructure, established strategic long-term contracts, and 
the  fact  that  our  pipelines  have  numerous  receipt  and  delivery  points  along  our  systems  provide  us  a  competitive 
advantage, especially along the eastern seaboard and northwestern United States.

Midstream Business

Competition  for  natural  gas  gathering,  processing,  treating,  transporting,  and  storing  natural  gas  continues  to 
increase as production from shales and other resource areas continues to grow. Our midstream services compete with 
similar facilities that are in the same proximity as our assets.

We face competition from major and independent natural gas midstream providers, private equity firms, and major 
integrated oil and natural gas companies that gather, transport, process, fractionate, store, and market natural gas and 
NGLs, as well as some larger exploration and production companies that are choosing to develop midstream services 
to handle their own natural gas.

Our gathering and processing agreements are generally long-term agreements that may include acreage dedication. 
We primarily face competition to the extent these agreements approach renewal and new volume opportunities arise.  
Competition for natural gas volumes is primarily based on reputation, commercial terms (products retained or fees 
charged), array of services provided, efficiency and reliability of services, location of gathering facilities, available 
capacity,  downstream  interconnects,  and  latent  capacity. We  believe  our  significant  presence  in  traditional  prolific 
supply basins, our solid positions in growing shale plays, our reputation as a reliable operator, and our ability to offer 
integrated packages of services position us well against our competition.

For additional information regarding competition for our services or otherwise affecting our business, please refer 
to Part 1, Item 1A. “Risk Factors” - “The financial condition of our natural gas transportation and midstream businesses 
is dependent on the continued availability of natural gas supplies in the supply basins that we access and demand for 
those supplies in the markets we serve,” “Our industry is highly competitive and increased competitive pressure could 
adversely affect our business and operating results,” and “We may not be able to replace, extend, or add additional 
customer contracts or contracted volumes on favorable terms, or at all, which could affect our financial condition, the 
amount of cash available to pay dividends, and our ability to grow.”

At February 1, 2019, we had 5,322 full-time employees.

terms;

•  Development and rate of adoption of alternative energy sources;

•  The impact of operational and developmental hazards and unforeseen interruptions;

•  The impact of existing and future laws and regulations (including but not limited to the Tax Cuts and Jobs Act 
of 2017), the regulatory environment, environmental liabilities, and litigation, as well as our ability to obtain 
necessary permits and approvals, and achieve favorable rate proceeding outcomes;

•  Our costs and funding obligations for defined benefit pension plans and other postretirement benefit plans;

•  Changes in maintenance and construction costs, as well as our ability to obtain sufficient construction related 

inputs including skilled labor;

•  Changes in the current geopolitical situation;

•  Our exposure to the credit risk of our customers and counterparties;

•  Risks related to financing, including restrictions stemming from debt agreements, future changes in credit 
ratings as determined by nationally recognized credit rating agencies, and the availability and cost of capital;

•  The amount of cash distributions from and capital requirements of our investments and joint ventures in which 

we participate;

•  Risks associated with weather and natural phenomena, including climate conditions and physical damage to 

our facilities;

•  Acts of terrorism, cybersecurity incidents, and related disruptions; 

•  Additional risks described in our filings with the Securities and Exchange Commission.

Given the uncertainties and risk factors that could cause our actual results to differ materially from those contained 
in any forward-looking statement, we caution investors not to unduly rely on our forward-looking statements. We 
disclaim any obligations to and do not intend to update the above list or announce publicly the result of any revisions 
to any of the forward-looking statements to reflect future events or developments.

20

In addition to causing our actual results to differ, the factors listed above and referred to below may cause our 
intentions to change from those statements of intention set forth in this report. Such changes in our intentions may also 
cause our results to differ. We may change our intentions, at any time and without notice, based upon changes in such 
factors, our assumptions, or otherwise.

Because forward-looking statements involve risks and uncertainties, we caution that there are important factors, 
in addition to those listed above, that may cause actual results to differ materially from those contained in the forward-
looking statements. These factors are described in the following section.

RISK FACTORS 

You should carefully consider the following risk factors in addition to the other information in this report. Each 
of these factors could adversely affect our business, prospects, financial condition, results of operations, cash flows, 
and, in some cases our reputation. The occurrence of any of such risks could also adversely affect the value of an 
investment in our securities.

Risks Related to Our Business

The financial condition of our natural gas transportation and midstream businesses is dependent on the continued 
availability of natural gas supplies in the supply basins that we access and demand for those supplies in the markets 
we serve.

Our ability to maintain and expand our natural gas transportation and midstream businesses depends on the level 
of drilling and production by third parties in our supply basins. Production from existing wells and natural gas supply 
basins with access to our pipeline and gathering systems will naturally decline over time. The amount of natural gas 
reserves underlying these existing wells may also be less than anticipated, and the rate at which production from these 
reserves declines may be greater than anticipated. We do not obtain independent evaluations of natural gas reserves 
connected to our systems and processing facilities. Accordingly, we do not have independent estimates of total reserves 
dedicated to our systems or the anticipated life of such reserves. In addition, low prices for natural gas, regulatory 
limitations, or the lack of available capital could adversely affect the development and production of additional natural 
gas reserves, the installation of gathering, storage, and pipeline transportation facilities and the import and export of 
natural gas supplies. Localized low natural gas prices in one or more of our existing supply basins, whether caused by 
a lack of infrastructure or otherwise, could also result in depressed natural gas production in such basins and limit the 
supply of natural gas made available to us. The competition for natural gas supplies to serve other markets could also 
reduce the amount of natural gas supply for our customers. A failure to obtain access to sufficient natural gas supplies 
will adversely impact our ability to maximize the capacities of our gathering, transportation, and processing facilities.

Demand for our services is dependent on the demand for gas in the markets we serve. Alternative fuel sources 
such as electricity, coal, fuel oils, or nuclear energy, as well as technological advances and renewable sources of energy, 
could reduce demand for natural gas in our markets and have an adverse effect on our business.

A failure to obtain access to sufficient natural gas supplies or a reduction in demand for our services in the markets 
we serve could result in impairments of our assets and have a material adverse effect on our business, financial condition, 
results of operations, and cash flows.

Prices for natural gas, NGLs, oil, and other commodities, are volatile and this volatility has and could continue to 
adversely affect our financial results, cash flows, access to capital, and ability to maintain our existing businesses.

Our revenues, operating results, future rate of growth, and the value of certain components of our businesses 
depend primarily upon the prices of natural gas, NGLs, oil, or other commodities, and the differences between prices 
of these commodities and could be materially adversely affected by an extended period of low commodity prices, or 
a decline in commodity prices. Price volatility has and could continue to impact both the amount we receive for our 
products and services and the volume of products and services we sell. Prices affect the amount of cash flow available 

21

for capital expenditures and our ability to borrow money or raise additional capital. Price volatility has and could 
continue to have an adverse effect on our business, results of operations, financial condition, and cash flows.

The markets for natural gas, NGLs, oil, and other commodities are likely to continue to be volatile. Wide fluctuations 

in prices might result from one or more factors beyond our control, including:

•  Worldwide and domestic supplies of and demand for natural gas, NGLs, oil, and related commodities;

•  Turmoil in the Middle East and other producing regions;

•  The activities of the Organization of Petroleum Exporting Countries;

•  The level of consumer demand;

•  The price and availability of other types of fuels or feedstocks;

•  The availability of pipeline capacity;

•  Supply disruptions, including plant outages and transportation disruptions;

•  The price and quantity of foreign imports and domestic exports of natural gas and oil;

•  Domestic and foreign governmental regulations and taxes;

•  The credit of participants in the markets where products are bought and sold.

We are exposed to the credit risk of our customers and counterparties, and our credit risk management will not be 
able to completely eliminate such risk.

We  are  subject  to  the  risk  of  loss  resulting  from  nonpayment  and/or  nonperformance  by  our  customers  and 
counterparties in the ordinary course of our business. Generally, our customers are rated investment grade, are otherwise 
considered creditworthy, or are required to make prepayments or provide security to satisfy credit concerns. However, 
our credit procedures and policies cannot completely eliminate customer and counterparty credit risk. Our customers 
and counterparties include industrial customers, local distribution companies, natural gas producers, and marketers 
whose creditworthiness may be suddenly and disparately impacted by, among other factors, commodity price volatility, 
deteriorating energy market conditions, and public and regulatory opposition to energy producing activities. In a low 
commodity price environment certain of our customers could be negatively impacted, causing them significant economic 
stress including, in some cases, to file for bankruptcy protection or to renegotiate contracts. To the extent one or more 
of our key customers commences bankruptcy proceedings, our contracts with the customers may be subject to rejection 
under applicable provisions of the United States Bankruptcy Code, or may be renegotiated. Further, during any such 
bankruptcy proceeding, prior to assumption, rejection or renegotiation of such contracts, the bankruptcy court may 
temporarily authorize the payment of value for our services less than contractually required, which could have a material 
adverse effect on our business, financial condition, results of operations, and cash flows. If we fail to adequately assess 
the creditworthiness of existing or future customers and counterparties or otherwise do not take or are unable to take 
sufficient mitigating actions, including obtaining sufficient collateral, deterioration in their creditworthiness, and any 
resulting increase in nonpayment and/or nonperformance by them could cause us to write down or write off accounts 
receivable. Such write-downs or write-offs could negatively affect our operating results in the periods in which they 
occur, and, if significant, could have a material adverse effect on our business, financial condition, results of operations, 
and cash flows.

22

We face opposition to operation and expansion of our pipelines and facilities from various individuals and groups.

We have experienced, and we anticipate that we will continue to face, opposition to the operation and expansion 
of our pipelines and facilities from governmental officials, environmental groups, landowners, tribal groups, local 
groups and other advocates. In some instances, we encounter opposition which disfavors hydrocarbon-based energy 
supplies regardless of practical implementation or financial considerations. Opposition to our operation and expansion 
can take many forms, including the delay or denial of required governmental permits, organized protests, attempts to 
block or sabotage our operations, intervention in regulatory or administrative proceedings involving our assets, or 
lawsuits or other actions designed to prevent, disrupt or delay the operation or expansion of our assets and business. 
In  addition,  acts  of  sabotage  or  eco-terrorism  could  cause  significant  damage  or  injury  to  people,  property  or  the 
environment or lead to extended interruptions of our operations. Any such event that delays or prevents the expansion 
of  our  business,  that  interrupts  the  revenues  generated  by  our  operations,  or  which  causes  us  to  make  significant 
expenditures not covered by insurance, could adversely affect our financial condition and results of operations.

We may not be able to grow or effectively manage our growth.

As part of our growth strategy, we consider acquisition opportunities and engage in significant capital projects. 
We have both a project lifecycle process and an investment evaluation process. These are processes we use to identify, 
evaluate, and execute on acquisition opportunities and capital projects. We may not always have sufficient and accurate 
information  to  identify  and  value  potential  opportunities  and  risks  or  our  investment  evaluation  process  may  be 
incomplete or flawed. Regarding potential acquisitions, suitable acquisition candidates or assets may not be available 
on terms and conditions we find acceptable or, where multiple parties are trying to acquire an acquisition candidate or 
assets, we may not be chosen as the acquirer. If we are able to acquire a targeted business, we may not be able to 
successfully integrate the acquired businesses and realize anticipated benefits in a timely manner. 

Our growth may also be dependent upon the construction of new natural gas gathering, transportation, compression, 
processing or treating pipelines, and facilities, NGL transportation, or fractionation or storage facilities as well as the 
expansion of existing facilities. Additional risks associated with construction may include the inability to obtain rights-
of-way, skilled labor, equipment, materials, and other required inputs in a timely manner such that projects are completed, 
on time or at all, and the risk that construction cost overruns could cause total project costs to exceed budgeted costs. 
Additional risks associated with growing our business include, among others, that:

•  Changing circumstances and deviations in variables could negatively impact our investment analysis, including 
our  projections  of  revenues,  earnings,  and  cash  flow  relating  to  potential  investment  targets,  resulting  in 
outcomes which are materially different than anticipated;

•  We could be required to contribute additional capital to support acquired businesses or assets;

•  We may assume liabilities that were not disclosed to us, that exceed our estimates and for which contractual 

protections are either unavailable or prove inadequate;

•  Acquisitions  could  disrupt  our  ongoing  business,  distract  management,  divert  financial  and  operational 
resources from existing operations and make it difficult to maintain our current business standards, controls, 
and procedures;

•  Acquisitions and capital projects may require substantial new capital, including proceeds from the issuance 

of debt or equity, and we may not be able to access capital markets or obtain acceptable terms.

If  realized,  any  of  these  risks  could  have  an  adverse  impact  on  our  financial  condition,  results  of  operations, 

including the possible impairment of our assets, or cash flows.

23

Holders of our common stock may not receive dividends in the amount expected or any dividends.

We may not have sufficient cash each quarter to pay dividends or maintain current or expected levels of dividends. 
The actual amount of cash we dividend may fluctuate from quarter to quarter and will depend on various factors, some 
of which are beyond our control, including:

•  The amount of cash that our subsidiaries distribute to us;

•  The  amount  of  cash  we  generate  from  our  operations,  our  working  capital  needs,  our  level  of  capital 

expenditures, and our ability to borrow;

•  The restrictions contained in our indentures and credit facility and our debt service requirements;

•  The cost of acquisitions, if any.

A failure either to pay dividends or to pay dividends at expected levels could result in a loss of investor confidence, 

reputational damage, and a decrease in the value of our stock price.

Our  industry  is  highly  competitive  and  increased  competitive  pressure  could  adversely  affect  our  business  and 
operating results.

We have numerous competitors in all aspects of our businesses, and additional competitors may enter our markets. 
Any current or future competitor that delivers natural gas, NGLs, or other commodities into the areas that we operate 
could offer transportation services that are more desirable to shippers than those we provide because of price, location, 
facilities or other factors.  In addition, current or potential competitors may make strategic acquisitions or have greater 
financial  resources  than  we  do,  which  could  affect  our  ability  to  make  strategic  investments  or  acquisitions.  Our 
competitors may be able to respond more quickly to new laws or regulations or emerging technologies or to devote 
greater resources to the construction, expansion, or refurbishment of their facilities than we can. Failure to successfully 
compete against current and future competitors could have a material adverse effect on our business, results of operations, 
financial condition, and cash flows.

We do not own 100 percent of the equity interests of certain subsidiaries, including the Partially Owned Entities, 
which may limit our ability to operate and control these subsidiaries. Certain operations, including the Partially 
Owned  Entities,  are  conducted  through  arrangements  that  may  limit  our  ability  to  operate  and  control  these 
operations.

The operations of our current non-wholly-owned subsidiaries, including the Partially Owned Entities, are conducted 
in accordance with their organizational documents. We anticipate that we will enter into more such arrangements, 
including through new joint venture structures or new Partially Owned Entities. We may have limited operational 
flexibility in such current and future arrangements and we may not be able to control the timing or amount of cash 
distributions received. In certain cases:

•  We cannot control the amount of cash reserves determined to be necessary to operate the business, which 

reduces cash available for distributions;

•  We cannot control the amount of capital expenditures that we are required to fund and we are dependent on 

third parties to fund their required share of capital expenditures;

•  We may be subject to restrictions or limitations on our ability to sell or transfer our interests in the jointly 

owned assets;

•  We may be forced to offer rights of participation to other joint venture participants in the area of mutual interest;

24

•  We have limited ability to influence or control certain day to day activities affecting the operations;

•  We may have additional obligations, such as required capital contributions, that are important to the success 

of the operations.

In addition, conflicts of interest may arise between us, on the one hand, and other interest owners, on the other 
hand. If such conflicts of interest arise, we may not have the ability to control the outcome with respect to the matter 
in question. Disputes between us and other interest owners may also result in delays, litigation or operational impasses.

The risks described above or the failure to continue such arrangements could adversely affect our ability to conduct 
the operations that are the subject of such arrangements which could, in turn, negatively affect our business, growth 
strategy, financial condition and results of operations.

We may not be able to replace, extend, or add additional customer contracts or contracted volumes on favorable 
terms, or at all, which could affect our financial condition, the amount of cash available to pay dividends, and our 
ability to grow.

We rely on a limited number of customers and producers for a significant portion of our revenues and supply of 
natural gas and NGLs. Although many of our customers and suppliers are subject to long-term contracts, if we are 
unable to replace or extend such contracts, add additional customers, or otherwise increase the contracted volumes of 
natural gas provided to us by current producers, in each case on favorable terms, if at all, our financial condition, growth 
plans, and the amount of cash available to pay dividends could be adversely affected. Our ability to replace, extend, or 
add additional customer or supplier contracts, or increase contracted volumes of natural gas from current producers, 
on favorable terms, or at all, is subject to a number of factors, some of which are beyond our control, including:

•  The level of existing and new competition in our businesses or from alternative sources, such as electricity, 

renewable resources, coal, fuel oils, or nuclear energy;

•  Natural  gas  and  NGL  prices,  demand,  availability,  and  margins  in  our  markets.  Higher  prices  for  energy 
commodities related to our businesses could result in a decline in the demand for those commodities and, 
therefore, in customer contracts or throughput on our pipeline systems. Also, lower energy commodity prices 
could negatively impact our ability to maintain or achieve favorable contractual terms, including pricing, and 
could also result in a decline in the production of energy commodities resulting in reduced customer contracts, 
supply contracts, and throughput on our pipeline systems;

•  General economic, financial markets, and industry conditions;

•  The effects of regulation on us, our customers, and our contracting practices;

•  Our ability to understand our customers’ expectations, efficiently and reliably deliver high quality services 
and effectively manage customer relationships. The results of these efforts will impact our reputation and 
positioning in the market.

Certain of our gas pipeline services are subject to long-term, fixed-price contracts that are not subject to adjustment, 
even if our cost to perform such services exceeds the revenues received from such contracts.

Our gas pipelines provide some services pursuant to long-term, fixed-price contracts. It is possible that costs to 
perform services under such contracts will exceed the revenues our pipelines collect for their services. Although most 
of the services are priced at cost-based rates that are subject to adjustment in rate cases, under FERC policy, a regulated 
service provider and a customer may mutually agree to sign a contract for service at a “negotiated rate” that may be 
above or below the FERC regulated cost-based rate for that service. These “negotiated rate” contracts are not generally 
subject to adjustment for increased costs that could be produced by inflation or other factors relating to the specific 
facilities being used to perform the services.

25

Some of our businesses are exposed to supplier concentration risks arising from dependence on a single or a limited 
number of suppliers.

Some of our businesses may be dependent on a small number of suppliers for delivery of critical goods or services. 
If a supplier on which one of our businesses depends were to fail to timely supply required goods and services, such 
business may not be able to replace such goods and services in a timely manner or otherwise on favorable terms or at 
all. If our business is unable to adequately diversify or otherwise mitigate such supplier concentration risks and such 
risks were realized, such businesses could be subject to reduced revenues and increased expenses, which could have a 
material adverse effect on our financial condition, results of operation, and cash flows.

Failure of our service providers or disruptions to our outsourcing relationships might negatively impact our ability 
to conduct our business.

Certain of our accounting and information technology services are currently provided by third-party vendors, and 
sometimes from service centers outside of the United States. Services provided pursuant to these agreements could be 
disrupted. Similarly, the expiration of such agreements or the transition of services between providers could lead to 
loss of institutional knowledge or service disruptions. Our reliance on others as service providers could have a material 
adverse effect on our business, financial condition, results of operations, and cash flows.

An impairment of our assets, including property, plant, and equipment, intangible assets, and/or equity-method 
investments, could reduce our earnings.

GAAP requires us to test certain assets for impairment on either an annual basis or when events or circumstances 
occur which indicate that the carrying value of such assets might be impaired. The outcome of such testing could result 
in impairments of our assets including our property, plant, and equipment, intangible assets, and/or equity-method 
investments. Additionally,  any  asset  monetizations  could  result  in  impairments  if  any  assets  are  sold  or  otherwise 
exchanged for amounts less than their carrying value. If we determine that an impairment has occurred, we would be 
required to take an immediate noncash charge to earnings.

Our operations are subject to operational hazards and unforeseen interruptions.

There are operational risks associated with the gathering, transporting, storage, processing, and treating of natural 
gas,  the  fractionation,  transportation,  and  storage  of  NGLs,  and  crude  oil  transportation  and  production  handling, 
including:

•  Aging infrastructure and mechanical problems;

•  Damages to pipelines and pipeline blockages or other pipeline interruptions;

•  Uncontrolled releases of natural gas (including sour gas), NGLs, crude oil, or other products;

•  Collapse or failure of storage caverns;

•  Operator error;

•  Damage caused by third-party activity, such as operation of construction equipment;

•  Pollution and other environmental risks;

•  Fires, explosions, craterings, and blowouts;

•  Security risks, including cybersecurity;

26

•  Operating in a marine environment.

Any of these risks could result in loss of human life, personal injuries, significant damage to property, environmental 
pollution, impairment of our operations, loss of services to our customers, reputational damage, and substantial losses 
to us. The location of certain segments of our facilities in or near populated areas, including residential areas, commercial 
business centers, and industrial sites, could increase the level of damages resulting from these risks. An event such as 
those  described  above  could  have  a  material  adverse  effect  on  our  financial  condition  and  results  of  operations, 
particularly if the event is not fully covered by insurance.

We do not insure against all potential risks and losses and could be seriously harmed by unexpected liabilities or by 
the inability of our insurers to satisfy our claims.

In accordance with customary industry practice, we maintain insurance against some, but not all, risks and losses, 
and only at levels we believe to be appropriate. The occurrence of any risks not fully covered by our insurance could 
have a material adverse effect on our business, financial condition, results of operations, and cash flows and our ability 
to repay our debt.

Our assets and operations, as well as our customers’ assets and operations, can be adversely affected by weather 
and other natural phenomena.

Our assets and operations, especially those located offshore, and our customers’ assets and operations can be 
adversely affected by hurricanes, floods, earthquakes, landslides, tornadoes, fires, and other natural phenomena and 
weather conditions, including extreme or unseasonable temperatures, making it more difficult for us to realize the 
historic rates of return associated with our assets and operations. A significant disruption in our or our customers’ 
operations or a significant liability for which we are not fully insured could have a material adverse effect on our 
business, financial condition, results of operations, and cash flows.

Our business could be negatively impacted by acts of terrorism and related disruptions.

Given the volatile nature of the commodities we transport, process, store, and sell, our assets and the assets of our 
customers and others in our industry may be targets of terrorist activities. A terrorist attack could create significant 
price volatility, disrupt our business, limit our access to capital markets, or cause significant harm to our operations, 
such as full or partial disruption to our ability to produce, process, transport, or distribute natural gas, NGLs, or other 
commodities. Acts of terrorism, as well as events occurring in response to or in connection with acts of terrorism, could 
cause environmental repercussions that could result in a significant decrease in revenues or significant reconstruction 
or  remediation  costs,  which  could  have  a  material  adverse  effect  on  our  business,  financial  condition,  results  of 
operations, and cash flows.

A breach of our information technology infrastructure, including a breach caused by a cybersecurity attack on us 
or third parties with whom we are interconnected, may interfere with the safe operation of our assets, result in the 
disclosure of personal or proprietary information, and harm our reputation.

We  rely  on  our  information  technology  infrastructure  to  process,  transmit,  and  store  electronic  information, 
including information we use to safely operate our assets. Our Board of Directors has oversight responsibility with 
regard to assessment of the major risks inherent in our business, including cybersecurity risks, and reviews management’s 
efforts  to  address  and  mitigate  such  risks,  including  the  establishment  and  implementation  of  policies  to  address 
cybersecurity threats. We have invested, and expect to continue to invest, significant time, manpower and capital in 
our information technology infrastructure. However, the age, operating systems, or condition of our current information 
technology infrastructure and software assets and our ability to maintain and upgrade such assets could affect our ability 
to resist cybersecurity threats. While we believe that we maintain appropriate information security policies, practices, 
and protocols, we regularly face cybersecurity and other security threats to our information technology infrastructure, 
which could include threats to our operational industrial control systems that are used to operate our pipelines, plants, 
and assets. We face unlawful attempts to gain access to our information technology infrastructure, including coordinated 

27

attacks from hackers, whether state-sponsored groups, “hacktivists”, or private individuals. We face the threat of theft 
and misuse of sensitive data and information, including customer and employee information. We also face attempts to 
gain access to information related to our assets through attempts to obtain unauthorized access by targeting acts of 
deception  against  individuals  with  legitimate  access  to  physical  locations  or  information.  We  also  are  subject  to 
cybersecurity risks arising from the fact that our business operations are interconnected with third parties, including 
third-party pipelines, other facilities and our contractors and vendors. In addition, the breach of certain business systems 
could  affect  our  ability  to  correctly  record,  process  and  report  financial  information.  Breaches  in  our  information 
technology infrastructure or physical facilities, or other disruptions including those arising from theft, vandalism, fraud, 
or unethical conduct, could result in damage to or destruction of our assets, unnecessary waste, safety incidents, damage 
to the environment, reputational damage, potential liability, the loss of contracts, the imposition of significant costs 
associated with remediation and litigation, heightened regulatory scrutiny, increased insurance costs, and a material 
adverse effect on our operations, financial condition, results of operations, and cash flows.

If  third-party  pipelines  and  other  facilities  interconnected  to  our  pipelines  and  facilities  become  unavailable  to 
transport natural gas and NGLs or to treat natural gas, our revenues could be adversely affected.

We depend upon third-party pipelines and other facilities that provide delivery options to and from our pipelines 
and facilities for the benefit of our customers. Because we do not own these third-party pipelines or other facilities, 
their  continuing  operation  is  not  within  our  control.  If  these  pipelines  or  facilities  were  to  become  temporarily  or 
permanently unavailable for any reason, or if throughput were reduced because of testing, line repair, damage to pipelines 
or  facilities,  reduced  operating  pressures,  lack  of  capacity,  increased  credit  requirements  or  rates  charged  by  such 
pipelines or facilities or other causes, we and our customers would have reduced capacity to transport, store or deliver 
natural gas or NGL products to end use markets or to receive deliveries of mixed NGLs, thereby reducing our revenues. 
Any temporary or permanent interruption at any key pipeline interconnect or in operations on third-party pipelines or 
facilities that would cause a material reduction in volumes transported on our pipelines or our gathering systems or 
processed, fractionated, treated, or stored at our facilities could have a material adverse effect on our business, financial 
condition, results of operations, and cash flows.

Our operating results for certain components of our business might fluctuate on a seasonal basis.

Revenues from certain components of our business can have seasonal characteristics. In many parts of the country, 
demand for natural gas and other fuels peaks during the winter. As a result, our overall operating results in the future 
might fluctuate substantially on a seasonal basis. Demand for natural gas and other fuels could vary significantly from 
our expectations depending on the nature and location of our facilities and pipeline systems and the terms of our natural 
gas transportation arrangements relative to demand created by unusual weather patterns.

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

We do not own all of the land on which our pipelines and facilities have been constructed. As such, we are subject 
to the possibility of increased costs to retain necessary land use. In those instances in which we do not own the land 
on which our facilities are located, we obtain the rights to construct and operate our pipelines and gathering systems 
on land owned by third parties and governmental agencies for a specific period of time. In addition, some of our facilities 
cross Native American lands pursuant to rights-of-way of limited terms. We may not have the right of eminent domain 
over  land  owned  by  Native American  tribes.  Our  loss  of  these  rights,  through  our  inability  to  renew  right-of-way 
contracts or otherwise, could have a material adverse effect on our business, financial condition, results of operations, 
and cash flows.

Our business could be negatively impacted as a result of stockholder activism.

In recent years, stockholder activism, including threatened or actual proxy contests, has been directed against 
numerous public companies, including ours. During the latter part of fiscal year 2016, we were the target of a proxy 
contest from a stockholder activist, which resulted in our incurring significant costs. If stockholder activists were to 
again take or threaten to take actions against the Company or seek to involve themselves in the governance, strategic 
direction or operations of the Company, we could incur significant costs as well as the distraction of management, 

28

which could have an adverse effect on our business or financial results. In addition, actions of activist stockholders 
may cause significant fluctuations in our stock price based on temporary or speculative market perceptions or other 
factors that do not necessarily reflect the underlying fundamentals and prospects of our business.

Our costs and funding obligations for our defined benefit pension plans and costs for our other postretirement 
benefit plans are affected by factors beyond our control.

We have defined benefit pension plans covering substantially all of our U.S. employees and other postretirement 
benefit plans covering certain eligible participants. The timing and amount of our funding requirements under the 
defined benefit pension plans depend upon a number of factors that we control, including changes to pension plan 
benefits, as well as factors outside of our control, such as asset returns, interest rates, and changes in pension laws. 
Changes to these and other factors that can significantly increase our funding requirements could have a significant 
adverse effect on our financial condition and results of operations.

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

Events such as an aging workforce without appropriate replacements, mismatch of skill sets to future needs, or 
unavailability of contract labor may lead to operating challenges such as lack of resources, loss of knowledge, and a 
lengthy time period associated with skill development, including with the workforce needs associated with projects 
and ongoing operations. Failure to hire and adequately obtain replacement employees, including the ability to transfer 
significant internal historical knowledge and expertise to the new employees, or the future availability and cost of 
contract labor may adversely affect our ability to manage and operate the businesses. If we are unable to successfully 
attract and retain an appropriately qualified workforce, results of operations could be negatively impacted.

If there is a determination that the spin-off of WPX Energy, Inc. (WPX) stock to our stockholders is taxable for U.S. 
federal income tax purposes because the facts, representations or undertakings underlying a U.S. Internal Revenue 
Service private letter ruling or a tax opinion are incorrect or for any other reason, then we and our stockholders 
could incur significant income tax liabilities.

In connection with our original separation plan that called for an initial public offering (IPO) of stock of WPX and 
a subsequent spin-off of our remaining shares of WPX to our stockholders, we obtained a private letter ruling from the 
IRS and an opinion of our outside tax advisor, to the effect that the distribution by us of WPX shares to our stockholders, 
and any related restructuring transaction undertaken by us, would not result in recognition for U.S. federal income tax 
purposes, of income, gain or loss to us or our stockholders under section 355 and section 368(a)(1)(D) of the U.S. 
Internal Revenue Code of 1986, as amended (Code), except for cash payments made to our stockholders in lieu of 
fractional shares of WPX common stock. In addition, we received an opinion from our outside tax advisor to the effect 
that the spin-off pursuant to our revised separation plan which was ultimately consummated on December 31, 2011, 
which did not involve an IPO of WPX shares, would not result in the recognition, for federal income tax purposes, of 
income, gain, or loss to us or our stockholders under section 355 and section 368(a)(1)(D) of the Code, except for cash 
payments made to our stockholders in lieu of fractional shares of WPX. The private letter ruling and opinion have relied 
on or will rely on certain facts, representations, and undertakings from us and WPX regarding the past and future 
conduct of the companies’ respective businesses and other matters. If any of these facts, representations, or undertakings 
are, or become, incorrect or are not otherwise satisfied, including as a result of certain significant changes in the stock 
ownership of us or WPX after the spin-off, or if the IRS disagrees with any such facts and representations upon audit, 
we and our stockholders may not be able to rely on the private letter ruling or the opinion of our tax advisor and could 
be subject to significant income tax liabilities.

Risks Related to Financing Our Business

Downgrades of our credit ratings, which are determined outside of our control by independent third parties, impact 
our liquidity, access to capital, and our costs of doing business.

Downgrades of our credit ratings increase our cost of borrowing and could require us to provide collateral to our 
counterparties, negatively impacting our available liquidity. In addition, our ability to access capital markets could 
continue to be limited by the downgrading of our credit ratings.

29

Credit rating agencies perform independent analysis when assigning credit ratings. This analysis includes a number 
of criteria such as, business composition, market, and operational risks, as well as various financial tests. Credit rating 
agencies continue to review the criteria for industry sectors and various debt ratings and may make changes to those 
criteria from time to time. Credit ratings are subject to revision or withdrawal at any time by the ratings agencies. As 
of the date of the filing of this report, we have been assigned an investment-grade credit rating by each of the three 
credit ratings agencies.

Difficult conditions in the global financial markets and the economy in general could negatively affect our business 
and results of operations.

Our businesses may be negatively impacted by adverse economic conditions or future disruptions in global financial 
markets. Included among these potential negative impacts are industrial or economic contraction leading to reduced 
energy demand and lower prices for our products and services and increased difficulty in collecting amounts owed to 
us by our customers. If financing is not available when needed, or is available only on unfavorable terms, we may be 
unable to implement our business plans or otherwise take advantage of business opportunities or respond to competitive 
pressures. In addition, financial markets have periodically been affected by concerns over U.S. fiscal and monetary 
policies. These concerns, as well as actions taken by the U.S. federal government in response to these concerns, could 
significantly and adversely impact the global and U.S. economies and financial markets, which could negatively impact 
us in the manner described above.

Restrictions in our debt agreements and the amount of our indebtedness may affect our future financial and operating 
flexibility.

Our total outstanding long-term debt (including current portion) as of December 31, 2018, was $22.4 billion.

The agreements governing our indebtedness contain covenants that restrict our and our material subsidiaries’ ability 
to incur certain liens to support indebtedness and our ability to merge or consolidate or sell all or substantially all of 
our assets in certain circumstances. In addition, certain of our debt agreements contain various covenants that restrict 
or limit, among other things, our ability to make certain distributions during the continuation of an event of default, 
the ability of our subsidiaries to incur additional debt, and our, and our material subsidiaries’, ability to enter into certain 
affiliate transactions and certain restrictive agreements. Certain of our debt agreements also contain, and those we enter 
into in the future may contain, financial covenants, and other limitations with which we will need to comply.

Our debt service obligations and the covenants described above could have important consequences. For example, 

they could:

•  Make it more difficult for us to satisfy our obligations with respect to our indebtedness, which could in turn 

result in an event of default on such indebtedness;

• 

Impair  our  ability  to  obtain  additional  financing  in  the  future  for  working  capital,  capital  expenditures, 
acquisitions, general corporate purposes, or other purposes;

•  Diminish our ability to withstand a continued or future downturn in our business or the economy generally;

•  Require us to dedicate a substantial portion of our cash flow from operations to debt service payments, thereby 
reducing  the  availability  of  cash  for  working  capital,  capital  expenditures,  acquisitions,  the  payments  of 
dividends, general corporate purposes, or other purposes;

•  Limit our flexibility in planning for, or reacting to, changes in our business and the industry in which we 
operate, including limiting our ability to expand or pursue our business activities and preventing us from 
engaging in certain transactions that might otherwise be considered beneficial to us.

30

Our ability to comply with our debt covenants, to repay, extend, or refinance our existing debt obligations and to 
obtain future credit will depend primarily on our operating performance. Our ability to refinance existing debt obligations 
or obtain future credit will also depend upon the current conditions in the credit markets and the availability of credit 
generally. If we are unable to comply with these covenants, meet our debt service obligations, or obtain future credit 
on favorable terms, or at all, we could be forced to restructure or refinance our indebtedness, seek additional equity 
capital or sell assets. We may be unable to obtain financing or sell assets on satisfactory terms, or at all.

Our failure to comply with the covenants in the documents governing our indebtedness could result in events of 
default, which could render such indebtedness due and payable. We may not have sufficient liquidity to repay our 
indebtedness in such circumstances. In addition, cross-default or cross-acceleration provisions in our debt agreements 
could cause a default or acceleration to have a wider impact on our liquidity than might otherwise arise from a default 
or acceleration of a single debt instrument. For more information regarding our debt agreements, please read Note 14 
– Debt, Banking Arrangements, and Leases of Notes to Consolidated Financial Statements.

Increases  in  interest  rates  could  adversely  impact  our  share  price,  our  ability  to  issue  equity  or  incur  debt  for 
acquisitions or other purposes, and our ability to make cash dividends at our intended levels.

Interest rates may increase in the future. As a result, interest rates on future credit facilities and debt offerings could 
be higher than current levels, causing our financing costs to increase accordingly. As with other yield-oriented securities, 
our share price will be impacted by the level of our dividends and implied dividend yield. The dividend yield is often 
used by investors to compare and rank yield-oriented securities for investment decision-making purposes. Therefore, 
changes in interest rates, either positive or negative, may affect the yield requirements of investors who invest in our 
shares, and a rising interest rate environment could have an adverse impact on our share price and our ability to issue 
equity or incur debt for acquisitions or other purposes and to pay cash dividends at our intended levels.

Our hedging activities might not be effective and could increase the volatility of our results.

In an effort to manage our financial exposure related to commodity price and market fluctuations, we have entered, 
and may in the future enter into contracts to hedge certain risks associated with our assets and operations. In these 
hedging activities, we have used, and may in the future use, fixed-price, forward, physical purchase, and sales contracts, 
futures, financial swaps, and option contracts traded in the over-the-counter markets or on exchanges. Nevertheless, 
no single hedging arrangement can adequately address all risks present in a given contract. For example, a forward 
contract that would be effective in hedging commodity price volatility risks would not hedge the contract’s counterparty 
credit  or  performance  risk. Therefore,  unhedged  risks  will  always  continue  to  exist. While  we  attempt  to  manage 
counterparty credit risk within guidelines established by our credit policy, we may not be able to successfully manage 
all credit risk and as such, future cash flows and results of operations could be impacted by counterparty default.

Risks Related to Regulations

The natural gas sales, transportation, and storage operations of our gas pipelines are subject to regulation by the 
FERC, which could have an adverse impact on their ability to establish transportation and storage rates that would 
allow them to recover the full cost of operating their respective pipelines, including a reasonable rate of return.

In addition to regulation by other federal, state, and local regulatory authorities, interstate pipeline transportation 

and storage service is subject to regulation by the FERC. Federal regulation extends to such matters as:

•  Transportation and sale for resale of natural gas in interstate commerce;

•  Rates, operating terms, types of services, and conditions of service;

•  Certification and construction of new interstate pipelines and storage facilities;

•  Acquisition, extension, disposition, or abandonment of existing interstate pipelines and storage facilities;

31

•  Accounts and records;

•  Depreciation and amortization policies;

•  Relationships with affiliated companies who are involved in marketing functions of the natural gas 

business;

•  Market manipulation in connection with interstate sales, purchases, or transportation of natural gas.

Regulatory or administrative actions in these areas, including successful complaints or protests against the rates 
of the gas pipelines, can affect our business in many ways, including decreasing tariff rates and revenues, decreasing 
volumes in our pipelines, increasing our costs, and otherwise altering the profitability of our pipeline business.

The operation of our businesses might be adversely affected by regulatory proceedings, changes in government 
regulations or in their interpretation or implementation, or the introduction of new laws or regulations applicable 
to our businesses or our customers.

Public and regulatory scrutiny of the energy industry has resulted in the proposal and/or implementation of increased 
regulations.  Such  scrutiny  has  also  resulted  in  various  inquiries,  investigations,  and  court  proceedings,  including 
litigation of energy industry matters. Both the shippers on our pipelines and regulators have rights to challenge the rates 
we charge under certain circumstances. Any successful challenge could materially affect our results of operations.

Certain inquiries, investigations, and court proceedings are ongoing. Adverse effects may continue as a result of 
the uncertainty of ongoing inquiries, investigations, and court proceedings, or additional inquiries and proceedings by 
federal or state regulatory agencies or private plaintiffs. In addition, we cannot predict the outcome of any of these 
inquiries or whether these inquiries will lead to additional legal proceedings against us, civil or criminal fines and/or 
penalties, or other regulatory action, including legislation, which might be materially adverse to the operation of our 
business and our results of operations or increase our operating costs in other ways. Current legal proceedings or other 
matters, including environmental matters, suits, regulatory appeals, and similar matters might result in adverse decisions 
against us which, among other outcomes, could result in the imposition of substantial penalties and fines and could 
damage our reputation. The result of such adverse decisions, either individually or in the aggregate, could be material 
and may not be covered fully or at all by insurance.

In addition, existing regulations, including those pertaining to financial assurances to be provided by our businesses 
in respect of potential asset decommissioning and abandonment activities, might be revised, reinterpreted, or otherwise 
enforced in a manner which differs from prior regulatory action. New laws and regulations, including those pertaining 
to oil and gas hedging and cash collateral requirements, might also be adopted or become applicable to us, our customers, 
or our business activities. If new laws or regulations are imposed relating to oil and gas extraction, or if additional or 
revised levels of reporting, regulation, or permitting moratoria are required or imposed, including those related to 
hydraulic fracturing, the volumes of natural gas and other products that we transport, gather, process, and treat could 
decline, our compliance costs could increase, and our results of operations could be adversely affected.

Our operations are subject to environmental laws and regulations, including laws and regulations relating to climate 
change and greenhouse gas emissions, which may expose us to significant costs, liabilities, and expenditures that 
could exceed our expectations.

Our operations are subject to extensive federal, state, tribal, and local laws and regulations governing environmental 
protection, endangered and threatened species, the discharge of materials into the environment, and the security of 
industrial facilities. Substantial costs, liabilities, delays, and other significant issues related to environmental laws and 
regulations are inherent in the gathering, transportation, storage, processing, and treating of natural gas, fractionation, 
transportation, and storage of NGLs, and crude oil transportation and production handling as well as waste disposal 
practices and construction activities. Failure to comply with these laws, regulations, and permits may result in the 
assessment of administrative, civil and/or criminal penalties, the imposition of remedial obligations, the imposition of 

32

stricter conditions on or revocation of permits, the issuance of injunctions limiting or preventing some or all of our 
operations, and delays or denials in granting permits.

Joint and several, strict liability may be incurred without regard to fault under certain environmental laws and 
regulations, for the remediation of contaminated areas and in connection with spills or releases of materials associated 
with natural gas, oil, and wastes on, under or from our properties and facilities. Private parties, including the owners 
of properties through which our pipeline and gathering systems pass and facilities where our wastes are taken for 
reclamation or disposal, may have the right to pursue legal actions to enforce compliance as well as to seek damages 
for noncompliance with environmental laws and regulations or for personal injury or property damage arising from 
our operations. Some sites at which we operate are located near current or former third-party hydrocarbon storage and 
processing or oil and natural gas operations or facilities, and there is a risk that contamination has migrated from those 
sites to ours.

We are generally responsible for all liabilities associated with the environmental condition of our facilities and 
assets, whether acquired or developed, regardless of when the liabilities arose and whether they are known or unknown. 
In connection with certain acquisitions and divestitures, we could acquire, or be required to provide indemnification 
against, environmental liabilities that could expose us to material losses, which may not be covered by insurance. In 
addition,  the  steps  we  could  be  required  to  take  to  bring  certain  facilities  into  compliance  could  be  prohibitively 
expensive, and we might be required to shut down, divest or alter the operation of those facilities, which might cause 
us to incur losses.

In addition, climate change regulations and the costs associated with the regulation of emissions of greenhouse 
gases (GHGs) have the potential to affect our business. Regulatory actions by the Environmental Protection Agency 
or the passage of new climate change laws or regulations could result in increased costs to operate and maintain our 
facilities, install new emission controls on our facilities, or administer and manage our GHG compliance program. If 
we are unable to recover or pass through a significant level of our costs related to complying with climate change 
regulatory requirements imposed on us, it could have a material adverse effect on our results of operations and financial 
condition. To  the  extent  financial  markets  view  climate  change  and  GHG  emissions  as  a  financial  risk,  this  could 
negatively impact our cost of and access to capital. Climate change and GHG regulation could also reduce demand for 
our services.

We expect that certain aspects of the Tax Cuts and Jobs Act signed into law on December 22, 2017 (Tax Reform), 
including regulatory liabilities relating to reduced corporate federal income tax rates, could adversely impact our 
financial condition and our future financial results. 

Tax Reform made significant changes to the U.S. federal income tax rules applicable to both individuals and 
entities, including among other things, a reduction in corporate federal income tax rates.  The rates we charge to our 
customers are subject to the rate-making policies of the FERC.  These policies permit us to include in our cost-of-
service an income tax allowance that includes a deferred income tax component.  Although we expect the decreased 
federal income tax rates will require us to return amounts to certain customers through future rates and have recognized 
a regulatory liability, the details of any regulatory implementation guidance remain uncertain. 

Item 1B.  Unresolved Staff Comments  

Not applicable.

Item 2.  Properties

Please read “Business” for a description of the location and general character of our principal physical properties. 
We generally own our facilities, although a substantial portion of our pipeline and gathering facilities is constructed 
and maintained pursuant to rights-of-way, easements, permits, licenses, or consents on and across properties owned by 
others.

Item 3.  Legal Proceedings 

Environmental

Certain  reportable  legal  proceedings  involving  governmental  authorities  under  federal,  state,  and  local  laws 
regulating the discharge of materials into the environment are described below. While it is not possible for us to predict 
the final outcome of the proceedings which are still pending, we do not anticipate a material effect on our consolidated 
financial position if we receive an unfavorable outcome in any one or more of such proceedings.

On June 13, 2013, an explosion and fire occurred at our formerly owned Geismar olefins plant and rendered the 
facility temporarily inoperable (Geismar Incident). On October 21, 2013, the EPA, Region 6, issued an Inspection 
Report pursuant to the Clean Air Act’s Risk Management Program following its inspection of the facility on June 24 
through  June  28,  2013. The  report  notes  the  EPA’s  preliminary  determinations  about  the  facility’s  documentation 
regarding process safety, process hazard analysis, as well as operating procedures, employee training, and other matters. 
On June 16, 2014, we received a request for information related to the Geismar Incident from the EPA under Section 
114 of the Clean Air Act to which we responded on August 13, 2014. The EPA could issue penalties pertaining to final 
determinations.

On February 21, 2017, we received notice from the Environmental Enforcement Section of the United States 
Department of Justice (DOJ) regarding certain alleged violations of the Clean Air Act at our Moundsville facility as 
set forth in a Notice of Noncompliance issued by the EPA on January 14, 2016. The notice includes an offer to avoid 
further legal action on the alleged violations by paying $2 million. In discussion with the DOJ and the EPA, the EPA 
has indicated its belief that additional similar violations have occurred at our Oak Grove facility and has expressed 
interest in pursuing a global settlement. On July 23, 2018, we received an offer from the DOJ to globally settle the 
government’s claim for civil penalties associated with the alleged violations at both the Moundsville and the Oak Grove 
facilities for $1.6 million. We are continuing to work with the agencies to resolve this matter.

On May 5, 2017, we entered into a Consent Order with the Georgia Department of Natural Resources, Environmental 
Protection Division (GADNR) pertaining to alleged violations of the Georgia Water Quality Control Act and associated 
rules arising from a permit issued by GADNR for construction of Transco’s Dalton expansion project. Pursuant to the 
Consent Order, we paid a fine of $168,750 and agreed to perform a Corrective Action Plan, the completion of which 
is pending.

On March 19, 2018, we received a Notice of Violation from the EPA, Region 8, regarding certain alleged violations 
of the Clean Air Act at our Ignacio Gas Plant in Durango, Colorado, following a previous on-site inspection of the 
facility. We were subsequently informed that this matter has been referred to the DOJ for handling. The Notice of 
Violation does not contain an initial penalty assessment. We have responded to the alleged violations and continue to 
work with the agencies to resolve this matter.

On March 20, 2018, we also received a Notice of Violation from the EPA, Region 8, regarding certain alleged 
violations of the Clean Air Act at our Parachute Creek Gas Plant in Parachute, Colorado, following a previous on-site 
inspection of the facility. We were informed that this matter has been referred to the DOJ for handling. The Notice of 
Violation does not contain an initial penalty assessment. We have responded to the alleged violations and continue to 
work with the agencies to resolve this matter.

On August 27, 2018, Northwest Pipeline LLC received a Notice of Violation/Cease and Desist Order from the 
Colorado Department of Public Health & Environment regarding certain alleged violations of the Colorado Water 
Quality Control Act and its General Permit under the Colorado Discharge Permit System related to its stormwater 
management practices at two construction sites. The Notice of Violation does not contain an initial penalty assessment. 
We have responded to the alleged violations and continue to work with the agency to resolve this matter.

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

General

We are an energy infrastructure company focused on connecting North America’s significant hydrocarbon resource 
plays to growing markets for natural gas and NGLs through our gas pipeline and midstream business. Our operations 
are located in the United States.

Our interstate natural gas pipeline strategy is to create value by maximizing the utilization of our pipeline capacity 
by  providing  high  quality,  low  cost  transportation  of  natural  gas  to  large  and  growing  markets.  Our  gas  pipeline 
businesses’ interstate transmission and storage activities are subject to regulation by the FERC and as such, our rates 
and charges for the transportation of natural gas in interstate commerce, and the extension, expansion or abandonment 
of jurisdictional facilities and accounting, among other things, are subject to regulation. The rates are established through 
the FERC’s ratemaking process. Changes in commodity prices and volumes transported have limited near-term impact 
on these revenues because the majority of cost of service is recovered through firm capacity reservation charges in 
transportation rates.

The  ongoing  strategy  of  our  midstream  operations  is  to  safely  and  reliably  operate  large-scale  midstream 
infrastructure where our assets can be fully utilized and drive low per-unit costs. We focus on consistently attracting 
new  business  by  providing  highly  reliable  service  to  our  customers. These  services  include  natural  gas  gathering, 
processing,  treating,  and  compression,  NGL  fractionation  and  transportation,  crude  oil  production  handling  and 
transportation, marketing services for NGL, oil and natural gas, as well as storage facilities.

Prior to our merger with Williams Partners L.P., our previously consolidated master limited partnership, in August 
2018,  we  had  one  reportable  segment, Williams  Partners.  Beginning  in  the  third-quarter  2018,  consistent  with  the 
manner in which our chief operating decision maker evaluates performance and allocates resources, our operations are 
now presented within the following reportable segments: Northeast G&P, Atlantic-Gulf, and West. Prior period segment 
disclosures have been recast for the new segment presentation. Our reportable segments are comprised of the following 
businesses:

•  Northeast G&P is comprised of our midstream gathering and processing businesses in the Marcellus Shale 
region primarily in Pennsylvania, New York, and West Virginia and the Utica Shale region of eastern Ohio, 
as well as a 66 percent interest in Cardinal (a consolidated entity), a 62 percent equity-method investment in 
UEOM, a 69 percent equity-method investment in Laurel Mountain, a 58 percent equity-method investment 
in Caiman II, and Appalachia Midstream Services, LLC, which owns equity-method investments with an 
approximate average 66 percent interest in multiple gas gathering systems in the Marcellus Shale (Appalachia 
Midstream Investments).

•  Atlantic-Gulf is comprised of our interstate natural gas pipeline, Transco, and significant natural gas gathering 
and processing and crude oil production handling and transportation assets in the Gulf Coast region, including 
a 51 percent interest in Gulfstar One (a consolidated entity), which is a proprietary floating production system,  
and various petrochemical and feedstock pipelines in the Gulf Coast region, as well as a 50 percent equity-
method investment in Gulfstream, a 60 percent equity-method investment in Discovery, and a 41 percent 
interest in Constitution (a consolidated entity), which is developing a pipeline project (see Note 4 – Variable 
Interest Entities of Notes to Consolidated Financial Statements).

•  West is comprised of our interstate natural gas pipeline, Northwest Pipeline, and our gathering, processing, 
and treating operations in Colorado, Wyoming, and the Barnett Shale region of north-central Texas, the Eagle 
Ford Shale region of south Texas, the Haynesville Shale region of northwest Louisiana, and the Mid-Continent 
region which includes the Anadarko, Arkoma, Delaware, and Permian basins. This segment also includes our 
NGL  and  natural  gas  marketing  business,  storage  facilities,  an  undivided  50  percent  interest  in  an  NGL 
fractionator near Conway, Kansas, and a 50 percent equity-method investment in OPPL, a 50 percent interest 
in Jackalope (an equity-method investment following deconsolidation as of June 30, 2018), a 50 percent equity-
method investment in RMM, a 15 percent equity-method investment in Brazos Permian II, and our previously 
owned 50 percent equity-method investment in the Delaware basin gas gathering system (DBJV) in the Mid-

40

Continent region (see Note 6 – Investing Activities of Notes to Consolidated Financial Statements). West also 
included our former natural gas gathering and processing assets in the Four Corners area of New Mexico and 
Colorado (see Note 3 – Divestitures of Notes to Consolidated Financial Statements).

•  Other includes our previously owned operations, including an 88.5 percent undivided interest in an olefins 
production facility in Geismar, Louisiana, which was sold in July 2017 (see Note 3 – Divestitures of Notes to 
Consolidated Financial Statements), and a refinery grade propylene splitter in the Gulf region, which was sold 
in June 2017. This segment also included our previously owned Canadian assets, which included an oil sands 
offgas processing plant near Fort McMurray, Alberta, and an NGL/olefin fractionation facility at Redwater, 
Alberta. In September 2016, these Canadian operations were sold. Other also includes minor business activities 
that are not operating segments, as well as corporate operations.

Unless indicated otherwise, the following discussion and analysis of results of operations and financial condition 
and  liquidity  relates  to  our  current  continuing  operations  and  should  be  read  in  conjunction  with  the  consolidated 
financial statements and notes thereto included in Part II, Item 8 of this report.

Dividends

In December 2018, we paid a regular quarterly dividend of $0.34 per share. On February 20, 2019, our board of 

directors approved a regular quarterly dividend of $0.38 per share payable on March 25, 2019.

Overview

Net income (loss) attributable to The Williams Companies, Inc., for the year ended December 31, 2018, decreased 
by $2.329 billion compared to the year ended December 31, 2017, reflecting a $2.112 billion increase to the provision 
for income taxes driven by the absence of a 2017 benefit resulting from Tax Reform and a $159 million decrease in 
operating income. The decrease in operating income reflects an increase of $667 million in Impairment of certain assets 
and $403 million in lower gains from the sale of certain assets. These unfavorable changes were partially offset by the 
absence of $674 million in regulatory charges resulting from Tax Reform in 2017, and a $190 million increase in service 
revenues primarily resulting from expansion projects placed into service in 2017 and 2018.

WPZ Merger

On August 10, 2018, we completed our merger with Williams Partners L.P. (WPZ), pursuant to which we acquired 
all of the approximately 256 million publicly held outstanding common units of WPZ in exchange for 382 million shares 
of our common stock in a noncash equity transaction. Williams continued as the surviving entity. (See Note 1 – General, 
Description  of  Business,  Basis  of  Presentation,  and  Summary  of  Significant  Accounting  Policies  of  Notes  to 
Consolidated Financial Statements.)

FERC Income Tax Policy Revision

On  March  15,  2018,  the  FERC  issued  a  revised  policy  statement  (the  revised  policy  statement)  regarding  the 
recovery of income tax costs in rates of natural gas pipelines.  The FERC found that an impermissible double recovery 
results from granting a Master Limited Partnership (MLP) pipeline both an income tax allowance and a return on equity 
pursuant to the discounted cash flow methodology. As a result, the FERC will no longer permit an MLP pipeline to 
recover an income tax allowance in its cost of service.  The FERC further stated it will address the application of this 
policy to non-MLP partnership forms as those issues arise in subsequent proceedings. One of the benefits of the recent 
WPZ Merger is to allow our FERC-regulated pipelines to continue to recover an income tax allowance in their cost of 
service rates.

On July 18, 2018, the FERC issued an order dismissing the requests for rehearing and clarification of the revised 
policy statement. In addition, the FERC provided guidance that an MLP pipeline (or other pass-through entity) no 
longer recovering an income tax allowance pursuant to the revised policy may eliminate previously accumulated deferred 
income taxes (ADIT) from its cost of service instead of flowing these ADIT balances to ratepayers.  This guidance, if 
implemented, would significantly mitigate the impact of the revised policy statement.  However, the FERC stated that 
the revised policy statement and such guidance do not establish a binding rule but are instead expressions of general 

41

policy intent designed to provide guidance by notifying entities of the course of action the FERC intends to follow in 
future adjudications.  To the extent the FERC addresses these issues in future proceedings, it will consider any arguments 
regarding not only the application of the revised policy to the facts of the case, but also any arguments regarding the 
underlying validity of the policy itself.  The FERC’s guidance on ADIT likely will be challenged by customers and 
state commissions, which would result in a long period of revenue uncertainty for pipelines eliminating ADIT from 
their cost of service.  The WPZ Merger has the additional benefit of eliminating this uncertainty.

On March 15, 2018, the FERC also issued a Notice of Proposed Rulemaking proposing a filing process that will 
allow it to determine which natural gas pipelines may be collecting unjust and unreasonable rates in light of the recent 
reduction in the corporate income tax rate in the Tax Cuts and Jobs Act (Tax Reform) and the revised policy statement. 
On July 18, 2018, the FERC issued a Final Rule, retaining the filing requirement and reaffirming the options that 
pipelines have to either reflect the reduced tax rate or explain why no rate change is necessary. The FERC also clarified 
that a natural gas company organized as a pass-through entity and all of whose income or losses are consolidated on 
the federal income tax return of its corporate parent is considered to be subject to the federal corporate income tax and 
is thus eligible for a tax allowance. We believe this Final Rule and the previously discussed WPZ Merger allow for the 
continued recovery of income tax allowances in Transco’s and Northwest Pipeline’s rates. Transco’s August 31, 2018, 
general rate case filing reflects a tax allowance based on this clarification, and the FERC’s September 28, 2018, order 
in that rate case proceeding finds that Transco is exempt from the Final Rule’s Form 501-G filing requirement. In 
addition, on October 19, 2018, Northwest Pipeline filed a petition requesting that the FERC waive its Form 501-G 
filing requirement under this Final Rule because (i) the reduction in the corporate income tax is already addressed in 
Northwest  Pipeline’s  2017  rate  settlement,  and  (ii)  as  discussed  above,  the WPZ  Merger  allows  for  the  continued 
recovery of income tax allowances in Northwest Pipeline’s rates. The FERC agreed and granted Northwest Pipeline’s 
petition for waiver on November 19, 2018. On October 11, 2018 and December 6, 2018, Discovery Gas Transmission, 
LLC and Pine Needle LNG Company, LLC, respectively, filed their Form 501-Gs, including explanations as to why 
no adjustments to rates are needed.

On March 15, 2018, the FERC also issued a Notice of Inquiry seeking comments on the additional impacts of Tax 
Reform on jurisdictional rates, particularly whether, and if so how, the FERC should address changes relating to ADIT 
amounts after the corporate income tax rate reduction and bonus depreciation rules, as well as whether other features 
of Tax Reform require FERC action. We are evaluating the impact of these developments on our interstate natural gas 
pipelines and currently expect any associated impacts would be prospective and determined through subsequent rate 
proceedings. We also continue to monitor developments that may impact our regulatory liabilities resulting from Tax 
Reform. It is reasonably possible that future tariff-based rates collected by our interstate natural gas pipelines may be 
adversely impacted.

Revenue Recognition

As a result of the adoption of Accounting Standards Update 2014-09, Revenues from Contracts with Customers 
(ASC 606) in January 2018, we now record revenues for transactions where we receive noncash consideration, primarily 
in certain of our gas processing contracts that provide commodities as full or partial consideration for services provided. 
These revenues are reflected as Service revenues - commodity consideration in the Consolidated Statement of Operations. 
The costs associated with these revenues, primarily related to natural gas shrink replacement, are reported as Processing 
commodity  expenses. The  revenues  and  costs  associated  with  the  subsequent  sale  of  the  commodity  consideration 
received is reflected within Product sales and Product costs in the Consolidated Statement of Operations. Service 
revenues -  commodity  consideration  plus  Product  sales,  less  Product  costs  and  Processing  commodity  expenses
represents the margin that we have historically characterized as commodity margin. This presentation is being reflected 
prospectively in the Consolidated Statement of Operations. (See Note 1 – General, Description of Business, Basis of 
Presentation, and Summary of Significant Accounting Policies of Notes to Consolidated Financial Statements.)

Additionally, future revenues are impacted by application of the new accounting standard to certain contracts for 
which  we  received  prepayments  for  services  and  have  recorded  deferred  revenue  (contract  liabilities).    For  these 
contracts, which underwent modifications in periods prior to January 1, 2018, the modification is treated as a termination 
of the existing contract and the creation of a new contract.  The new accounting guidance requires that the transaction 
price, including any remaining deferred revenue from the old contract, be allocated to the performance obligations over 

42

the term of the new contract.  As a result, we will recognize the deferred revenue over longer periods than application 
of revenue recognition under accounting guidance prior to January 1, 2018.

Filing of Rate Case

On August 31, 2018, Transco filed a general rate case with the FERC for an overall increase in rates. In September 
2018, with the exception of certain rates that reflected a rate decrease, the FERC accepted and suspended our general 
rate filing to be effective March 1, 2019, subject to refund and the outcome of a hearing. The specific rates that reflected 
a rate decrease were accepted, without suspension, to be effective October 1, 2018, as requested by Transco, and will 
not be subject to refund. The impact of these specific new rates is expected to reduce revenues by approximately $2 
million per month beginning October 1, 2018.

RMM Equity-Method Investment

During the third quarter of 2018, our joint venture, RMM, purchased a natural gas and oil gathering and natural 
gas processing business in Colorado’s Denver-Julesburg basin. Our initial economic ownership was 40 percent, which 
has since increased to 50 percent at December 31, 2018, based on additional capital contributions made since the initial 
purchase. This investment is reported in the West segment.

Sale of Four Corners Assets

In October 2018, we completed the sale of our natural gas gathering and processing assets in the Four Corners 
area  of  New  Mexico  and  Colorado  for  total  consideration  of  $1.125  billion,  subject  to  customary  working  capital 
adjustments. These assets were designated as held for sale during the third quarter of 2018. As a result of this sale, we 
recorded a gain of approximately $591 million within the West segment in the fourth quarter of 2018  (see Note 3 – 
Divestitures of Notes to Consolidated Financial Statements).

Sale of Gulf Coast Pipeline Systems

In November 2018, we completed the sale of certain assets and operations located in the Gulf Coast area for $177 
million in cash. These assets were designated as held for sale during the third quarter of 2018. As a result of this sale, 
we recorded a gain of approximately $101 million in the fourth quarter of 2018, consisting of $81 million in our Atlantic-
Gulf segment and $20 million in Other (see Note 3 – Divestitures of Notes to Consolidated Financial Statements).

Brazos Permian II Equity-Method Investment

In December 2018, we entered into a joint venture partnership in the Delaware basin. Under the terms of the 
agreement, we contributed the majority of our existing Delaware basin assets in the West segment and $27 million in 
cash to the partnership in exchange for a 15 percent interest. Our partner operates the partnership, which consists of 
approximately  725  miles  of  gas  gathering  pipelines,  260  MMcf/d  of  natural  gas  processing,  75  miles  of  crude  oil 
gathering  pipelines,  and  75  thousand  barrels  of  oil  storage. The  partnership  anticipates  processing  capacity  in  the 
Delaware basin to reach 460 MMcf/d and will be supported by over 500,000 acres of long-term dedications from major 
and independent oil and gas producers. We recorded our interest in the partnership as an equity-method investment and 
recognized a gain on the deconsolidation of our contributed assets of $141 million (see Note 6 – Investing Activities
of Notes to Consolidated Financial Statements).

Expansion Project Updates

Significant expansion project updates for the period, including projects placed into service are described below. 

Ongoing major expansion projects are discussed later in Company Outlook.

Northeast G&P

Susquehanna Supply Hub

During the first quarter of 2018, the remaining facilities that comprise the Susquehanna Supply Hub Expansion 
were fully commissioned. The project added two new compression facilities with an additional 49,000 horsepower 

43

and 59 miles of 12-  to 24-inch pipeline, and increased gathering capacity, allowing a certain producer to fulfill its 
commitment to deliver 850 Mdth/d to our Atlantic Sunrise development.

Atlantic-Gulf

Gulf Connector

In January 2019, the Gulf Connector project was placed into service. This project expanded Transco’s existing 
natural gas transmission system to provide incremental firm transportation capacity from Station 65 in Louisiana 
to delivery points in Wharton and San Patricio Counties, Texas. The project increased capacity by 475 Mdth/d.

Atlantic Sunrise

In October 2018, the Atlantic Sunrise project was placed into service. This project expanded Transco’s existing 
natural gas transmission system along with greenfield facilities to provide incremental firm transportation capacity 
from the northeastern Marcellus producing area to markets along Transco’s mainline as far south as Station 85 in 
west central Alabama.  We placed a portion of the mainline project facilities into service in September 2017, which 
increased  capacity  by  400  Mdth/d.  We  placed  additional  mainline  facilities  into  service  in  June  2018,  which 
increased  capacity  by  an  additional  150  Mdth/d.  In  total,  the  project  increased  Transco’s  capacity  by                          
1,700 Mdth/d.

Garden State

In March 2018, Phase 2 of the Garden State Expansion project was placed into service. This project expanded 
Transco’s  existing  natural  gas  transmission  system  to  provide  incremental  firm  transportation  capacity  from 
Station 210 in New Jersey to a new interconnection on our Trenton Woodbury Lateral in New Jersey. Phase 1 of 
the  project  was  placed  into  service  in  September  2017,  and  together  Phases  1  and  2  increased  capacity  by          
180 Mdth/d.

Commodity Prices

NGL per-unit margins were approximately 19 percent higher in 2018 compared to 2017 primarily due to a 22 
percent increase in realized per-unit non-ethane prices and an approximate 9 percent decrease in per-unit natural gas 
feedstock prices.

NGL margins are defined as NGL revenues less any applicable Btu replacement cost, plant fuel, and third-party 
transportation and fractionation. Per-unit NGL margins are calculated based on sales of our own equity volumes at the 
processing plants. Our equity volumes include NGLs where we own the rights to the value from NGLs recovered at 
our plants under both “keep-whole” processing agreements, where we have the obligation to replace the lost heating 
value with natural gas, and “percent-of-liquids” agreements whereby we receive a portion of the extracted liquids with 
no obligation to replace the lost heating value. 

The potential impact of commodity prices on our business is further discussed in the following Company Outlook.

Company Outlook

Our strategy is to provide large-scale energy infrastructure designed to maximize the opportunities created by the 
vast supply of natural gas and natural gas products that exists in the United States. We accomplish this by connecting 
the growing demand for cleaner fuels and feedstocks with our major positions in the premier natural gas and natural 
gas  products  supply  basins.   We  continue  to  maintain  a  strong  commitment  to  safety,  environmental  stewardship, 
operational excellence, and customer satisfaction. We believe that accomplishing these goals will position us to deliver 
safe and reliable service to our customers and an attractive return to our shareholders.

Our business plan for 2019 includes a continued focus on growing our fee-based businesses, executing growth 
projects, including through joint ventures, and accomplishing cost discipline initiatives to ensure operations support 
our  strategy.    We  anticipate  operating  results  will  increase  through  organic  business  growth  driven  by  continued 
expansion in the Northeast region and Transco expansion projects. 

44

Our growth capital and investment expenditures in 2019 are expected to be in a range from $2.7 billion to $2.9 
billion.  Growth capital spending in 2019 includes Transco expansions, all of which are fully contracted with firm 
transportation agreements, and continuing to develop our gathering and processing infrastructure in the Northeast G&P 
and West segments.  In addition to growth capital and investment expenditures, we also remain committed to projects 
that maintain our assets for safe and reliable operations, as well as projects that meet legal, regulatory, and/or contractual 
commitments.

As a result of our significant continued capital and investment expenditures on Transco expansion projects and 
fee-based gathering and processing projects, fee-based businesses are a significant component of our portfolio and 
serve to reduce the influence of commodity price fluctuations on our operating results and cash flows.  We expect to 
benefit as continued growth in demand for low-cost natural gas is driven by increases in LNG exports, industrial demand 
and power generation.  For 2019, current forward market prices indicate oil, natural gas, and NGL prices are expected 
to be lower compared to 2018.  We continue to address certain pricing risks through the utilization of commodity 
hedging strategies.

 In 2019, our operating results are expected to include increases from our regulated Transco fee-based business,  
primarily related to projects recently placed in-service.  For our non-regulated businesses, we anticipate increases in 
fee-based revenue in the Northeast G&P segment associated with recent expansion projects, partially offset with a 
decrease in the West segment primarily due to recent asset divestitures.  We expect overall gathering and processing 
volumes to grow in 2019 for our continuing businesses and anticipate an increase in our equity earnings primarily 
associated with new investments.  Additionally, we believe general and administrative expenses will be slightly lower 
due to recent asset divestitures and the effect of the WPZ merger.

Potential risks and obstacles that could impact the execution of our plan include:

•  Opposition to, and legal regulations affecting, our infrastructure projects, including the risk of delay or denial 

in permits and approvals needed for our projects;

•  Unexpected significant increases in capital expenditures or delays in capital project execution;

•  Counterparty credit and performance risk;

•  Unexpected changes in customer drilling and production activities, which could negatively impact gathering 

and processing volumes;

•  Lower than anticipated demand for natural gas and natural gas products which could result in lower than 

expected volumes, energy commodity prices, and margins;

•  General economic, financial markets, or further industry downturn, including increased interest rates;

•  Physical damages to facilities, including damage to offshore facilities by named windstorms;

•  Other risks set forth under Part I, Item 1A. Risk Factors in this report.  

We seek to maintain a strong financial position and liquidity, as well as manage a diversified portfolio of energy 

infrastructure assets which continue to serve key growth markets and supply basins in the United States.

45

Expansion Projects

Our ongoing major expansion projects include the following: 

Northeast G&P

Ohio River Supply Hub Expansion

We agreed to expand our services for certain customers to provide additional rich gas processing capacity in 
the Marcellus and Upper Devonian Shale in West Virginia and Pennsylvania. Associated with these agreements, 
we plan to further expand the processing capacity of our Oak Grove facility up to 400 MMcf/d. With one of these 
customers, we secured a gathering dedication agreement to gather dry gas in this same region.  Additionally, we 
will be constructing a new NGL pipeline from Moundsville to the Harrison Hub fractionation facility to provide 
a new outlet for NGLs. These expansions will be supported by long-term, fee-based agreements and volumetric 
commitments.

Susquehanna Supply Hub Expansion

We continue to expand the gathering systems in the Susquehanna Supply Hub that are needed to meet our 
customers’ production plans by 2020.  This next expansion of the gathering infrastructure includes an additional 
40,000 horsepower of new compression and gathering pipelines to bring the capacity to approximately 4.5 Bcf/d.

Atlantic-Gulf 

Constitution Pipeline

We currently own 41 percent of Constitution with three other parties holding 25 percent, 24 percent, and 10 
percent, respectively. We are the operator of Constitution. The 126-mile Constitution pipeline is proposed to connect 
our gathering system in Susquehanna County, Pennsylvania, to the Iroquois Gas Transmission and Tennessee Gas 
Pipeline systems in New York, as well as to a local distribution company serving New York and Pennsylvania. 

In  December  2014,  Constitution  received  approval  from  the  FERC  to  construct  and  operate  its  proposed 
pipeline,  which  will  have  an  expected  capacity  of  650  Mdth/d.  However,  in April  2016,  the  New York  State 
Department of Environmental Conservation (NYSDEC) denied the necessary water quality certification under 
Section 401 of the Clean Water Act for the New York portion of the pipeline. In May 2016, Constitution appealed 
the NYSDEC’s denial of the Section 401 certification to the United States Court of Appeals for the Second Circuit 
and in August 2017, the court issued a decision denying in part and dismissing in part Constitution’s appeal. The 
court  expressly  declined  to  rule  on  Constitution’s  argument  that  the  delay  in  the  NYSDEC’s  decision  on 
Constitution’s Section 401 application constitutes a waiver of the certification requirement. The court determined 
that it lacked jurisdiction to address that contention and found that jurisdiction over the waiver issue lies exclusively 
with the United States Court of Appeals for the District of Columbia Circuit (D.C. Circuit). As to the denial itself, 
the  court  determined  that  NYSDEC’s  action  was  not  arbitrary  or  capricious.  Constitution  filed  a  petition  for 
rehearing with the Second Circuit Court of Appeals, but in October 2017 the court denied our petition. 

In October 2017, we filed a petition for declaratory order requesting the FERC to find that, by operation of 
law, the Section 401 certification requirement for the New York State portion of Constitution’s pipeline project 
was waived due to the failure by the NYSDEC to act on Constitution’s Section 401 application within a reasonable 
period of time as required by the express terms of such statute.  In January 2018, the FERC denied our petition, 
finding that Section 401 provides that a state waives certification only when it does not act on an application within 
one year from the date of the application. We filed a request for rehearing of the FERC’s decision, but in July 2018 
the FERC denied our request.

The project’s sponsors remain committed to the project.  On November 5, 2018, the FERC granted our request 
for an extension of time to December 2, 2020, to construct and place into service the Constitution pipeline.  And, 
in September 2018,  we filed a petition with the D.C. Circuit for review of the FERC’s denial of our petition for 
declaratory order.  (See Note 4 – Variable Interest Entities of Notes to Consolidated Financial Statements.)  

46

Gateway

In December 2018, we received approval from the FERC to expand Transco’s existing natural gas transmission 
system  to  provide  incremental  firm  transportation  capacity  from  PennEast  Pipeline  Company's  proposed 
interconnection with Transco’s mainline south of Station 205 in New Jersey to other existing Transco meter stations 
within New Jersey.  We plan to place the project into service in the first quarter of 2021, assuming timely receipt 
of all necessary regulatory approvals.  The project is expected to increase capacity by 65 Mdth/d.

Hillabee

In February 2016, the FERC issued a certificate order for the initial phases of Transco’s Hillabee Expansion 
Project. The project involves an expansion of Transco’s existing natural gas transmission system from Station 85 
in west central Alabama to a new interconnection with the Sabal Trail pipeline in Alabama.  The project is being 
constructed in phases, and all of the project expansion capacity is dedicated to Sabal Trail pursuant to a capacity 
lease agreement. We placed a portion of Phase I into service in June of 2017 and the remainder of Phase I into 
service in July of 2017.  Phase I increased capacity by 818 Mdth/d.  The in-service date of Phase II is planned for 
the second quarter of 2020, and together Phases I and II are expected to increase capacity by 1,025 Mdth/d.

Norphlet Project

In March 2016, we announced that we have reached an agreement to provide deepwater gas gathering services 
to the Appomattox development in the Gulf of Mexico. The project will provide offshore gas gathering services 
to our existing Transco lateral, which will provide transmission services onshore to our Mobile Bay processing 
facility. We completed modifications to our Main Pass 261 Platform to install an alternate delivery route from the 
platform, as well as modifications to our Mobile Bay processing facility. The project is scheduled to go into service 
during the second quarter of 2019.

Northeast Supply Enhancement 

In March 2017, we filed an application with the FERC to expand Transco’s existing natural gas transmission 
system to provide incremental firm transportation capacity from Station 195 in Pennsylvania to the Rockaway 
Delivery Lateral transfer point in New York.  On April 20, 2018, the NYSDEC denied, without prejudice, Transco’s 
application for certain permits required for the project. We addressed the technical issues identified by NYSDEC 
and in May 2018, we refiled our application for the permits.  We plan to place the project into service in the fourth 
quarter of 2020, assuming timely receipt of all necessary regulatory approvals.  The project is expected to increase 
capacity by 400 Mdth/d.

Rivervale South to Market

In August 2018, we received approval from the FERC to expand Transco’s existing natural gas transmission 
system  to  provide  incremental  firm  transportation  capacity  from  the  existing  Rivervale  interconnection  with 
Tennessee Gas Pipeline on Transco’s North New Jersey Extension to other existing Transco locations within New 
Jersey.  We plan to place the project into service as early as the fourth quarter of 2019, assuming timely receipt of 
all necessary regulatory approvals. The project is expected to increase capacity by 190 Mdth/d.

Southeastern Trail

In April 2018, we filed an application with the FERC to expand Transco’s existing natural gas transmission 
system to provide incremental firm transportation capacity from the Pleasant Valley interconnect with Dominion’s 
Cove Point Pipeline in Virginia to the Station 65 pooling point in Louisiana.  We plan to place the project into 
service in late 2020, assuming timely receipt of all necessary regulatory approvals.  The project is expected to 
increase capacity by 296 Mdth/d.

47

West

North Seattle Lateral Upgrade

In July 2018, we received approval from the FERC to expand delivery capabilities on Northwest Pipeline’s  
North Seattle Lateral.  The project consists of the removal and replacement of approximately 5.9 miles of 8-inch 
diameter pipeline with new 20-inch diameter pipeline.  We plan to place the project into service as early as the 
fourth quarter of 2019, assuming timely receipt of all necessary regulatory approvals.  The project is expected to 
increase delivery capacity by approximately 159 Mdth/d.

Wamsutter Expansion

We are expanding our gathering and processing infrastructure in the Wamsutter region of Wyoming in order 
to  meet  our  customers’  production  plans.   The  expansion  includes  the  addition  of  approximately  60  miles  of 
gathering pipelines and compression, and modifications to existing treating and processing facilities.  We plan to 
place the first phase of the project into service during the first quarter of 2019.

Project Bluestem

We are expanding our presence in the Mid-Continent region through building a 188-mile pipeline from our 
fractionator in Conway,  Kansas to an interconnect with a third-party NGL pipeline system in Oklahoma, providing 
us with firm access to Mt. Belvieu pricing.  As part of the project, the third-party intends to construct a 110-mile 
pipeline extension of their existing NGL pipeline system that will have an initial capacity of 120 Mbbls/d.  Further, 
we will have an option to purchase a 20 percent equity interest in a Mt. Belvieu fractionation train developed by 
the third party.  The pipeline and extension projects are expected to be placed into service during the first quarter 
of 2021.

Critical Accounting Estimates

The  preparation  of  financial  statements  in  conformity  with  generally  accepted  accounting  principles  requires 
management to make estimates and assumptions.  We believe that the nature of these estimates and assumptions is 
material due to the subjectivity and judgment necessary, or the susceptibility of such matters to change, and the impact 
of these on our financial condition or results of operations.

Pension and Postretirement Obligations 

We have employee benefit plans that include pension and other postretirement benefits. Net periodic benefit cost 
and obligations for these plans are impacted by various estimates and assumptions. These estimates and assumptions 
include the expected long-term rates of return on plan assets, discount rates, cash balance interest crediting rate, expected 
rate of compensation increase, and employee demographics, including retirement age and mortality. These assumptions 
are reviewed annually and adjustments are made as needed. The assumptions utilized to compute cost and the benefit 
obligations are shown in Note 10 – Employee Benefit Plans of Notes to Consolidated Financial Statements.

48

The following table presents the estimated increase (decrease) in net periodic benefit cost and obligations resulting 

from a one-percentage-point change in the specific assumption.

Our expected long-term rates of return on plan assets, as determined at the beginning of each fiscal year, are based 
on the average rate of return expected on the funds invested in the plans. We determine our long-term expected rates 
of return on plan assets using our expectations of capital market results, which include an analysis of historical results 
as well as forward-looking projections. These capital market expectations are based on a period of at least 10 years and 
take into account our investment strategy and mix of assets. We develop our expectations using input from our third-
party independent investment consultant. The forward-looking capital market projections start with current conditions 
of interest rates, equity pricing, economic growth, and inflation and those are overlaid with forward looking projections 
of normal inflation, growth, and interest rates to determine expected returns. The capital market return projections for 
specific asset classes in the investment portfolio are then applied to the relative weightings of the asset classes in the 
investment portfolio. The resulting rates are an estimate of future results and, thus, likely to be different than actual 
results.

Our expected long-term rate of return on plan assets used for our pension plans was 5.34 percent in 2018. The 
2018 actual return on plan assets for our pension plans was a loss of approximately 3.6 percent. The 10-year average 
rate of return on pension plan assets through December 2018 was approximately 8.3 percent. While the 2018 investment 
performance was less than our expected rates of return, the expected rates of return on plan assets are long-term in 
nature and are not significantly impacted by short-term market performance. Changes to our asset allocation would 
also impact the expected rates of return.

The discount rates are used to measure the benefit obligations of our pension and other postretirement benefit 
plans. The objective of the discount rates is to determine the amount, if invested at the December 31 measurement date 
in a portfolio of high-quality debt securities, that will provide the necessary cash flows when benefit payments are due. 
Increases in the discount rates decrease the obligation and, generally, decrease the related cost. The discount rates for 
our pension and other postretirement benefit plans are determined separately based on an approach specific to our plans 
and their respective expected benefit cash flows as described in Note 1 – General, Description of Business, Basis of 
Presentation, and Summary of Significant Accounting Policies and Note 10 – Employee Benefit Plans of Notes to 
Consolidated Financial Statements. Our discount rate assumptions are impacted by changes in general economic and 
market conditions that affect interest rates on long-term, high-quality debt securities as well as by the duration of our 
plans’ liabilities. 

The cash balance interest crediting rate assumption represents the average long-term rate by which the pension 
plans’ cash balance accounts are expected to grow. Interest on the cash balance accounts is based on the 30-year U.S. 
Treasury securities rate and is credited to the accounts quarterly. An increase in this rate causes the pension obligation 
and cost to increase.

The expected rate of compensation increase represents average long-term salary increases. An increase in this rate 

causes the pension obligation and cost to increase.

Property, Plant, and Equipment and Other Identifiable Intangible Assets

We evaluate our property, plant, and equipment and other identifiable intangible assets for impairment when events 
or changes in circumstances indicate, in our judgment, that the carrying value of such assets may not be recoverable. 
When an indicator of impairment has occurred, we compare our estimate of undiscounted future cash flows attributable 
to the assets to the carrying value of the assets to determine whether an impairment has occurred, and we may apply a 
probability-weighted approach to consider the likelihood of different cash flow assumptions and possible outcomes 
including selling in the near term or holding for the remaining estimated useful life. If an impairment of the carrying 
value has occurred, we determine the amount of the impairment recognized by estimating the fair value of the assets 
and recording a loss for the amount that the carrying value exceeds the estimated fair value. This evaluation is performed 
at the lowest level for which separately identifiable cash flows exist.

Certain of our contractual gathering rates, primarily those in the Barnett Shale, are based on a percentage of the 
New York Mercantile Exchange (NYMEX) natural gas prices. During the fourth quarter of 2018, we determined there 
was a sustained decline in the forward price curves for natural gas. During this same period, a large producer customer 
in the Barnett Shale removed their remaining drilling rig.  These factors gave rise to an impairment evaluation of these 
assets. The historical carrying value of our Barnett assets was initially recorded based on the estimated fair value during 
the third quarter of 2014 in conjunction with the acquisition of ACMP.

Our evaluation incorporated management’s projections of future drilling levels and gathering rates, taking into 
consideration the information noted above as well as recently available information regarding producer drilling cost 
assumptions in this basin. The resulting estimate of future undiscounted cash flows was less than our carrying value, 
necessitating the estimation of the fair value of these assets. In arriving at the fair value, we utilized an income approach 
with a discount rate of 8.5 percent, reflecting an estimated cost of capital and risks associated with the underlying assets. 
As a result, we recorded an impairment charge of $1.849 billion to reduce the carrying value to our estimate of fair 
value. A one-percentage-point increase in the discount rate would decrease our estimate of fair value by approximately 
$37 million.  

Judgments  and  assumptions  are  inherent  in  estimating  undiscounted  future  cash  flows,  fair  values,  and  the 
probability-weighting of possible outcomes. The use of alternate judgments and assumptions could result in a different 
determination affecting the consolidated financial statements.

Constitution Pipeline Capitalized Project Costs

As  of  December  31,  2018,  Property,  plant,  and  equipment  –  net  in  our  Consolidated  Balance  Sheet  includes 
approximately $377 million of capitalized project costs for Constitution, for which we are the construction manager 
and own a 41 percent consolidated interest. As a result of the events discussed in Company Outlook, we evaluated the 
capitalized project costs for impairment at December 31, 2017, and determined that no impairment was necessary. Our 
evaluation  considered  probability-weighted  scenarios  of  undiscounted  future  net  cash  flows,  including  scenarios 
assuming construction of the pipeline, as well as a scenario where the project does not proceed. These scenarios included 
our most recent estimate of total construction costs. Subsequently, there have been no events or changes in circumstances 
that impact our conclusion. It is reasonably possible that future unfavorable developments, such as a reduced likelihood 
of success, increased estimates of construction costs, or further significant delays, could result in a future impairment.  

Regulatory Liabilities resulting from Tax Reform

In December 2017, Tax Reform was enacted, which, among other things, reduced the corporate income tax rate 
from 35 percent to 21 percent. Rates charged to customers of our regulated natural gas pipelines are subject to the rate-
making policies of the FERC, which have historically permitted the recovery of an income tax allowance that includes 
a deferred income tax component. Due to the reduced income tax rate from Tax Reform and the collection of historical 
rates that reflected historical federal income tax rates, we expect that our regulated natural gas pipelines will be required 
to return amounts to certain customers through future rates. As a result, we established regulatory liabilities during 
2017 and at December 31, 2018, these liabilities total $657 million. The timing and actual amount of such return will 
be subject to future negotiations regarding this matter and many other elements of cost-of-service rate proceedings, 
including other costs of providing service.

2018 vs. 2017

Service revenues increased primarily due to higher transportation fee revenues at Transco associated with expansion 
projects placed in-service in 2017 and 2018, as well as higher gathering volumes at the Susquehanna Supply Hub and 

51

 
 
 
Ohio River Supply Hub. These increases are partially offset by a change in the rate of deferred revenue recognition 
resulting from implementing ASC 606, reduced revenues from our Four Corners area operations that were sold in 
October 2018, a reduction of rates resulting from a Northwest Pipeline rate case settlement, and a decrease following 
the Jackalope deconsolidation.

Service revenues - commodity consideration increased as the result of implementing ASC 606 using a modified 
retrospective approach, effective January 1, 2018. Therefore, prior periods have not been recast under the new guidance. 
These revenues represent consideration we receive in the form of commodities as full or partial payment for gathering 
and processing services provided. (See Note 1 – General, Description of Business, Basis of Presentation, and Summary 
of Significant Accounting Policies of Notes to Consolidated Financial Statements.) Most of these NGL volumes are 
sold within the month processed and therefore are offset in Product costs below.

Product sales increased primarily due to higher marketing revenues and higher system management gas sales, 
which are offset in Product costs, and higher sales from the production of our equity NGLs, reflecting higher NGL 
prices. These increases are partially offset by the absence of $269 million in olefin sales revenue associated with our 
former Gulf Olefins operations in 2017.

The increase in Product costs is primarily due to the impact of ASC 606 in which costs reflected in this line item 
for 2018 include volumes acquired as commodity consideration for NGL processing services, as well as higher marketing 
and system management gas costs. This increase is partially offset by the absence of $147 million of olefin feedstock 
costs due to the sale of our former Gulf Olefins operations, as well as the absence of natural gas purchases associated 
with the production of equity NGLs, which are now reported in Processing commodity expenses in conjunction with 
the implementation of ASC 606.

Processing commodity expenses presents the natural gas purchases associated with the production of equity NGLs 

as previously described in conjunction with the implementation of ASC 606.

Operating and maintenance expenses decreased primarily due to the absence of $80 million of costs associated 

with our former Gulf Olefins and Four Corners area operations. 

Depreciation and amortization expenses decreased primarily due to the absence of our former Gulf Olefins and 

Four Corners area operations, partially offset by new assets placed in-service.

Selling,  general,  and  administrative  expenses  decreased  primarily  due  to  the  absence  of  severance-related, 
organizational realignment, and Financial Repositioning costs incurred in 2017, $25 million in reduced costs associated 
with our former Gulf Olefins and Four Corners area operations, and ongoing cost containment efforts. These decreases 
are partially offset by a charitable contribution of preferred stock to The Williams Companies Foundation, Inc. (see 
Note 15 – Stockholders' Equity of Notes to Consolidated Financial Statements) and fees associated with the WPZ 
Merger.

The unfavorable change in  Impairment of certain assets includes 2018 impairments on certain assets in the Barnett 
Shale region and certain idle pipelines, partially offset by the absence of 2017 impairments associated with certain 
assets in the Mid-Continent, Marcellus South, and Houston Ship Channel areas (see Note 17 – Fair Value Measurements, 
Guarantees, and Concentration of Credit Risk of Notes to Consolidated Financial Statements).

The unfavorable change in Gain on sale of certain assets reflects the absence of a gain recognized on the sale of 
our Geismar Interest in July 2017, partially offset by gains recognized on the sales of our Four Corners area in October 
2018 and our Gulf Coast pipeline systems in December 2018 (see Note 3 – Divestitures of Notes to Consolidated 
Financial Statements).

Regulatory  charges  resulting  from  Tax  Reform  relates  to  the  2017  recognition  of  regulatory  liabilities  for  the 
probable return to customers through future rates of the future decrease in income taxes payable associated with Tax 
Reform. (See Note 1 – General, Description of Business, Basis of Presentation, and Summary of Significant Accounting 
Policies of Notes to Consolidated Financial Statements).

52

The  favorable  change  in  Other  (income)  expense  –  net  within  Operating  income  (loss)  includes  the  benefit  of 
establishing a regulatory asset associated with an increase in Transco’s estimated deferred state income tax rate following 
the WPZ Merger, substantially offset by the absence of gains from certain contract settlements and terminations in 
2017, the absence of a gain on the sale of our RGP Splitter in 2017, and 2018 charges establishing a regulatory liability 
associated with a decrease in Northwest Pipeline's estimated deferred state income tax rate following the WPZ Merger.

Operating income (loss) changed unfavorably primarily due to higher impairments of assets, lower gains on sales 
of assets, and the absence of operating income associated with our former Gulf Olefins and Four Corners area operations, 
partially offset by the absence of regulatory charges resulting from Tax Reform, higher Service revenues primarily from 
expansion projects, and an increase in NGL margins.

The unfavorable change in  Equity earnings (losses) is primarily due to a decrease in volumes at Discovery, partially 
offset by improved results at our Appalachia Midstream Investments and the deconsolidation of our Jackalope interest, 
which is now accounted for as an equity-method investment beginning in the second quarter of 2018.

The Impairment of equity-method investments in 2018 reflects an impairment related to our investment in UEOM.

Other investing income (loss) – net reflects the absence of the gain on disposition of our investments in DBJV and 
Ranch Westex JV LLC in 2017, partially offset by gains on the 2018 deconsolidations of certain Permian basin assets 
and of our interest in Jackalope. (See Note 6 – Investing Activities of Notes to Consolidated Financial Statements.)

Interest expense increased primarily due to an increase in other financing obligations associated with Transco's 
Dalton and Atlantic Sunrise projects, as well as expense related to the deemed financing component of certain contract 
liabilities resulting from our implementation of  ASC 606 in 2018, offset by lower interest rates on our outstanding 
debt in 2018 and lower borrowings on our credit facilities in 2018. (See Note 14 – Debt, Banking Arrangements, and 
Leases of Notes to Consolidated Financial Statements.)

Other income (expense) – net below Operating income (loss) changed favorably primarily due to a decrease in 
charges  reducing  regulatory  assets  related  to  deferred  taxes  on  the  allowance  for  funds  used  during  construction 
(AFUDC) resulting from Tax Reform, an increase in equity AFUDC, and a lower settlement charge from the pension 
early payout program, partially offset by a decrease due to the absence of a net gain on early retirement of debt in 2017 
and a loss on early retirement of debt in 2018. (See Note 7 – Other Income and Expenses of Notes to Consolidated 
Financial Statements.)

Provision (benefit) for income taxes changed unfavorably primarily due to the absence of a $1.923 billion tax 
provision benefit associated with Tax Reform and releasing a $127 million valuation allowance in 2017. The unfavorable 
change also reflects a $105 million valuation allowance in 2018 associated with certain foreign tax credits. See Note 
8 – Provision (Benefit) for Income Taxes of Notes to Consolidated Financial Statements for a discussion of the effective 
tax rate compared to the federal statutory rate for both periods.

The unfavorable change in Net income (loss) attributable to noncontrolling interests is primarily related to WPZ, 
reflective of both our acquisition of the publicly held interests in WPZ associated with the WPZ Merger and a fourth 
quarter 2017 net loss incurred by WPZ, partially offset by lower operating results at Gulfstar.

2017 vs. 2016

Service revenues increased due to higher transportation fee revenues at Transco and in the eastern Gulf reflecting 
expansion projects placed in-service in 2016 and 2017; partially offset by a decrease in gathering, processing, and 
fractionation revenue including lower rates, primarily in the Barnett Shale region associated with the restructuring of 
contracts in the fourth quarter of 2016; lower volumes in the western regions, driven by natural declines and extreme 
weather conditions in the Rocky Mountains in 2017; and the sale of our former Canadian and Gulf Olefins operations.

Product  sales  increased  primarily  due  to  higher  marketing  revenues  reflecting  significantly  higher  prices  and 
volumes. Revenues from the sale of our equity NGLs increased primarily due to higher non-ethane NGL prices, partially 
offset by lower volumes. These increases were partially offset by lower olefin production sales due to lower volumes 
resulting from the sale of our former Gulf Olefins and Canadian operations.

53

The increase in Product costs is primarily due to the same factors that increased marketing sales, partially offset 

by lower olefin feedstock purchases associated with the sale of our Gulf Olefins and Canadian operations.

Operating and maintenance expenses decreased primarily due to the absence of costs associated with our former 
Canadian  and  Gulf  Olefins  operations  and  lower  labor-related  costs  resulting  from  our  workforce  reductions  that 
occurred late in first-quarter 2016, and ongoing cost containment efforts, partially offset by higher pipeline integrity 
testing and general maintenance at Transco.

Depreciation and amortization expenses decreased primarily due to the absence of our former Canadian and Gulf 

Olefins operations, partially offset by new assets placed in-service.

Selling, general, and administrative expenses decreased primarily due to the absence of certain project development 
costs associated with the Canadian PDH facility that were expensed in 2016, lower labor-related costs resulting from 
our workforce reductions that occurred late in first-quarter 2016, ongoing cost containment efforts, lower strategic 
development costs, and the absence of costs associated with our former Canadian and Gulf Olefins operations. These 
decreases were partially offset by higher severance and organizational realignment costs in 2017 (see Note 7 – Other 
Income and Expenses of Notes to Consolidated Financial Statements).

The unfavorable change in  Impairment of certain assets reflects 2017 impairments of certain gathering operations 
in the Mid-Continent and Marcellus South regions, certain NGL pipeline assets, and an olefins pipeline project in the 
Gulf coast region. These 2017 impairments are partially offset by the absence of 2016 impairments of our former 
Canadian  operations  and  certain  Mid-Continent  assets  (see  Note  17  –  Fair Value  Measurements,  Guarantees,  and 
Concentration of Credit Risk of Notes to Consolidated Financial Statements).

The Gain on sale of certain assets reflects the gain recognized on the sale of our Geismar Interest in July 2017. 

(See Note 3 – Divestitures of Notes to Consolidated Financial Statements.)

Regulatory charges resulting from Tax Reform relates to the recognition of regulatory liabilities for the probable 
return to customers through future rates of the future decrease in income taxes payable associated with Tax Reform. 
(See Note 1 – General, Description of Business, Basis of Presentation, and Summary of Significant Accounting Policies
of Notes to Consolidated Financial Statements.)

The favorable change in Other (income) expense – net within Operating income (loss) includes the absence of the 
2016 loss on the sale of our Canadian operations, gains from certain contract settlements and terminations in 2017, a 
gain on the sale of our RGP Splitter in 2017, and the absence of an unfavorable change in foreign currency exchange 
associated with our former Canadian operations. These favorable changes are partially offset by additional expense 
associated with an annual revision to the ARO liability, accrual of additional expenses in 2017 related to the Geismar 
Incident, as well as the absence of a gain in first-quarter 2016 associated with the sale of unused pipe.

Operating income (loss) changed favorably primarily due to the Gain on sale of certain assets, the absence of the 
2016  impairments  of  certain  Mid-Continent  assets  and  our  former  Canadian  operations,  higher  service  revenues 
primarily from expansion projects placed in-service in 2016 and 2017, the absence of expensed Canadian PDH facility 
project development costs in 2016, as well as ongoing cost containment efforts, including workforce reductions in first-
quarter 2016. Operating income (loss) also improved due to the absence of a 2016 loss on the sale of our Canadian 
operations, the absence of an operating loss associated with our former Canadian operations, gains from certain contract 
settlements and the sale of our RGP Splitter. These favorable changes were partially offset by 2017 impairments of 
certain gathering operations in the Mid-Continent and Marcellus South regions and certain NGL pipeline assets, and 
regulatory charges resulting from Tax Reform, as well as the absence of operating income associated with our former 
Gulf Olefins operations. 

The favorable change in  Equity earnings (losses) is due to an increase in ownership of our Appalachia Midstream 
Investments and improved results at Aux Sable due to favorable pricing and higher volumes, partially offset by lower 
UEOM results driven by lower processing volumes from the Utica gathering system and lower Discovery results due 
to lower volumes. 

54

The  decrease  in  Impairment  of  equity-method  investments  reflects  the  absence  of  2016  impairment  charges 
associated with our Appalachia Midstream Investments, DBJV, Laurel Mountain, and Ranch Westex equity-method 
investments.  (See  Note  17  –  Fair Value  Measurements,  Guarantees,  and  Concentration  of  Credit  Risk  of  Notes  to 
Consolidated Financial Statements.) 

Other investing income (loss) – net reflects the gain on disposition of our investments in DBJV and Ranch Westex 
JV LLC in 2017, partially offset by the absence of interest income received in 2016 associated with a receivable related 
to the sale of certain former Venezuelan assets and the absence of a 2016 gain on the sale of an equity-method investment 
interest in a gathering system that was part of our Appalachia Midstream Investments. (See Note 6 – Investing Activities
of Notes to Consolidated Financial Statements.)

Interest expense decreased primarily due to lower Interest incurred primarily attributable to debt retirements in 
2017 and lower borrowings on our credit facilities in 2017. (See Note 14 – Debt, Banking Arrangements, and Leases
of Notes to Consolidated Financial Statements.)

Other income (expense) – net below Operating income (loss) changed unfavorably primarily due to charges reducing 
regulatory assets related to deferred taxes on equity funds used during construction (AFUDC) resulting from Tax Reform 
and a settlement charge from a pension early payout program (see Note 10 – Employee Benefit Plans of Notes to 
Consolidated Financial Statements), partially offset by a net gain on early debt retirements in 2017, and other favorable 
changes related to AFUDC. (See Note 7 – Other Income and Expenses of Notes to Consolidated Financial Statements.)

Provision (benefit) for income taxes changed favorably primarily due to a reduction in the federal statutory rate 
from 35 percent to 21 percent with the enactment of Tax Reform. The remeasurement of our existing deferred tax assets 
and liabilities at the reduced rate resulted in the recognition of a net income tax provision benefit of $1.923 billion. 
Adjustments within this provision benefit are considered provisional and are potentially subject to change in the future. 
See Note 8 – Provision (Benefit) for Income Taxes of Notes to Consolidated Financial Statements for a discussion of 
the effective tax rate compared to the federal statutory rate for both periods.

The unfavorable change in Net income (loss) attributable to noncontrolling interests is primarily due to the impact 
of decreased income allocated to us driven by the permanent waiver of IDRs and higher operating results at WPZ, 
partially offset by a decrease in the ownership of the noncontrolling interests. Both the permanent waiver of IDRs and 
the change in ownership are associated with the first-quarter 2017 Financial Repositioning (see Note 1 – General, 
Description of Business, and Basis of Presentation  of Notes to Consolidated Financial Statements). In addition, improved 
results in our Gulfstar operations also contributed to the increase in Net income (loss) attributable to noncontrolling 
interests, partially offset by lower results for our Cardinal gathering system.

Year-Over-Year Operating Results – Segments

We evaluate segment operating performance based upon Modified EBITDA. Note 19 – Segment Disclosures of 
Notes to Consolidated Financial Statements includes a reconciliation of this non-GAAP measure to Net income (loss). 
Management uses Modified EBITDA because it is an accepted financial indicator used by investors to compare company 
performance.  In addition, management believes that this measure provides investors an enhanced perspective of the 
operating performance of our assets. Modified EBITDA should not be considered in isolation or as a substitute for a 
measure of performance prepared in accordance with GAAP.

Northeast G&P Modified EBITDA increased primarily due to the absence of Impairment of certain assets in 2017, 

and higher Service revenues and Proportional Modified EBITDA of equity-method investments.

Service revenues increased due to: 

•  A $65 million increase in gathering fee revenues at Susquehanna Supply Hub due to 13 percent higher gathering 

volumes reflecting increased customer production;

•  A $24 million increase at Ohio River Supply Hub reflecting higher gathering volumes due to increased customer 

production; 

•  An $11 million increase in Utica gathering fee revenues reflecting higher rates and volumes.

Service revenues - commodity consideration increased as a result of implementing ASC 606 using a modified 
retrospective approach. These revenues represent consideration we receive in the form of commodities as full or partial 
payment for gathering and processing services provided. Most of these NGL volumes are sold within the month processed 
and therefore are offset in Processing commodity expenses below.

Product sales decreased primarily due to $31 million lower marketing sales, driven by lower non-ethane volumes 
and prices. The changes in marketing revenues are offset by similar changes in marketing purchases, reflected above 
as Product costs. The decrease in Product sales is partially offset by $21 million in higher system management gas 
sales. System management gas sales are offset in Product costs and therefore have no impact on Modified EBITDA.

Impairment of certain assets reflects the absence of a $115 million impairment of certain gathering operations in 

the Marcellus South region in 2017.

Proportional Modified EBITDA of equity-method investments increased primarily due to a $33 million increase at 
Appalachia Midstream Investments reflecting our increased ownership acquired in late first-quarter 2017 and higher 
volumes. Improvements at Aux Sable and Caiman II also contributed to the increase.

2017 vs. 2016 

Northeast  G&P  Modified  EBITDA  decreased  primarily  due  to  higher  Impairment  of  certain  assets  and  Other 
segment costs and expenses, partially offset by higher Proportional Modified EBITDA of equity-method investments.

56

Service revenues increased slightly reflecting:

•  A $38 million increase in gathering fee revenue at Susquehanna Supply Hub driven by 11 percent higher 

gathered volumes reflecting increased customer production; 

•  A $23 million increase in fee revenue at Ohio Valley Midstream reflecting the absence of shut-in volumes 

from the first half of 2016, as well as new production coming online;

•  A $56 million decrease in Utica gathering fee revenues primarily due to 14 percent lower gathered volumes 
driven by natural declines in the wet gas areas, partially offset by higher volumes from new development in 
the dry gas areas.

Product sales increased primarily due to higher non-ethane and ethane prices and higher non-ethane volumes 
within our marketing activities. The changes in marketing revenues are offset by similar changes in marketing purchases, 
reflected above as Product costs.

Other segment costs and expenses  increased due to a $31 million increase in operating and maintenance expenses 
primarily resulting from higher costs related to various maintenance expenses and ad valorem taxes, and $7 million 
related to a settlement charge from a pension early payout program (see Note 10 – Employee Benefit Plans of Notes 
to  Consolidated  Financial  Statements).  These  increases  are  partially  offset  by  $16  million  lower  general  and 
administrative expenses primarily due to a reduced share of allocated support costs, ongoing cost containment efforts, 
and 2016 workforce reductions.

Impairment of certain assets increased primarily due to a $115 million impairment of certain gathering operations 

in the Marcellus South region.

Proportional Modified EBITDA of equity-method investments changed favorably primarily due to a $100 million 
increase at Appalachia Midstream Investments reflecting our increased ownership acquired late in the first quarter of 
2017  and  higher  gathering  volumes  reflecting  the  absence  of  shut-in  volumes  from  2016  and  increased  customer 
production, a $20 million increase at Aux Sable due to increased customer production and the absence of the $9 million 
impairment in 2016, an $8 million increase at Laurel Mountain Midstream associated with higher gathering revenue 
due to higher rates reflecting higher natural gas prices, partially offset by a $34 million decrease at UEOM driven by 
lower processing volumes from the wet gas areas of the Utica gathering system as noted above.

2018 vs. 2017

Atlantic-Gulf Modified EBITDA increased primarily due to the absence of regulatory charges associated with the 
impact of Tax Reform at Transco, higher Service revenues, and a 2018 Gain on sale of certain assets; partially offset 
by lower Proportional Modified EBITDA of equity-method investments.

Service revenues increased primarily due to a $253 million increase in Transco’s natural gas transportation fee 
revenues primarily due to a $241 million increase associated with expansion projects placed in-service in 2017 and 
2018.

Service revenues – commodity consideration increased as a result of implementing ASC 606 using a modified 
retrospective approach. These revenues represent consideration we receive in the form of commodities as full or partial 
payment for gathering and processing services provided. Most of these NGL volumes are sold within the month processed 
and therefore are offset in Product costs below.

The decrease in Product sales includes:

•  A $90 million decrease in commodity marketing revenues driven by a $149 million decrease in crude oil 
revenues as this activity is now presented on a net basis within Product costs in conjunction with the adoption 
of ASC 606, partially offset by a $59 million increase in NGL marketing revenues primarily reflecting 20 
percent higher non-ethane prices;

•  A  $14 million decrease in revenues associated with our equity NGLs, as further described below as part of 

our commodity product margins;

•  A $57 million increase in system management gas sales. System management gas sales are offset in Product 

costs and therefore have little impact to Modified EBITDA.

Product  costs  slightly  increased  primarily  due  to  a  $59  million  increase  in  system  management  gas  costs 
(substantially offset in Product sales) and the impact of ASC 606 in which costs reflected in this line item for 2018 
include volumes acquired as commodity consideration for NGL processing services. This increase was partially offset 
by an $87 million decrease in marketing purchases (more than offset in Product sales) and the absence of natural gas 

58

purchases associated with the production of equity NGLs, which are now reported in Processing commodity expenses
in conjunction with the implementation of ASC 606.

Processing commodity expenses presents the natural gas purchases associated with the production of equity NGLs 

as previously described in conjunction with the implementation of ASC 606.

The  net  sum  of  Service  revenues  –  commodity  consideration,  Product  sales,  Product  costs,  and  Processing 

commodity expenses comprise our commodity product margins. 

Other segment costs and expenses decreased primarily due to a $17 million increase in Transco’s equity AFUDC 

as a result of projects placed in service in 2018.

Gain on sale of certain assets reflects an $81 million gain from the sale of our Gulf Coast pipeline system assets 

in fourth quarter 2018.

The decrease in Regulatory charges resulting from Tax Reform reflects the absence of $493 million of regulatory 
charges in 2017 associated with the impact of Tax Reform at Transco (See Note 1 – General, Description of Business, 
Basis of Presentation, and Summary of Significant Accounting Policies of Notes to Consolidated Financial Statements).

The decrease in Proportional Modified EBITDA of equity-method investments is due to an $89 million decrease 

at Discovery, primarily related to a $76 million decrease associated with production ending on certain wells.

2017 vs. 2016 

Atlantic-Gulf Modified EBITDA decreased primarily due to regulatory charges associated with the impact of Tax 
Reform at  our regulated entities, higher Other segment costs and expenses, and lower Proportional Modified EBITDA 
from Discovery,  partially offset by higher Service revenues.

Service revenues increased primarily due to:

•  A $135 million increase in Transco’s natural gas transportation fee revenues primarily due to a $150 million 
increase  associated  with  expansion  projects  placed  in-service  in  2016  and  2017,  partially  offset  by  lower 
volume-based transportation services revenues;

•  A $103 million increase in eastern Gulf Coast region fee revenues primarily related to the impact of new 
volumes at Gulfstar One related to the Gunflint expansion placed in-service in the third quarter of 2016, the 
absence of the temporary shut-down and subsequent ramp-up of Gulfstar One in the second and third quarters 
of 2016 to tie-in Gunflint, and the absence of producers’ operational issues in the Tubular Bells field during 
the first quarter of 2016, partially offset by lower volumes as a result of a temporary increase in 2016 due to 
disrupted operations of a competitor;

•  A $15 million increase in Transco’s storage revenue primarily related to the absence of an accrual for potential 

refunds associated with a ruling received in certain rate case litigation in 2016;

•  A $15 million decrease in western Gulf Coast region fee revenues due to lower volumes primarily associated 

with producer maintenance. 

Product sales increased primarily due to:

•  A $31 million increase in NGL and crude oil marketing revenues primarily due to a $72 million increase driven 
by higher prices, partially offset by a $41 million decrease driven by lower volumes. Average realized non-
ethane prices were 47 percent higher and average realized crude prices were 18 percent higher. Non-ethane 
volumes were 16 percent lower and crude volumes were 13 percent lower driven by shut-ins of certain wells 
behind Devils Tower as a result of production issues and temporary hurricane-related shut-ins. (Increases in 
marketing revenues are substantially offset by higher Product costs);

59

•  A $12 million increase in system management gas sales from Transco. System management gas sales are offset 

in Product costs and, therefore, have no impact on Modified EBITDA;

•  A $5 million decrease in revenues associated with our equity NGLs due to a $19 million decrease driven by 
lower volumes, partially offset by a $14 million increase driven by higher prices. Realized non-ethane prices 
increased by 32 percent. Non-ethane volumes decreased by 31 percent primarily as a result of a temporary 
increase in 2016 due to disrupted operations of a competitor.

Product costs increased primarily due to:

•  A $28 million increase in marketing purchases (more than offset in Product sales);

•  A $12 million increase in system management gas costs (offset in Product sales);

•  An $8 million decrease in natural gas purchases associated with the production of equity NGLs primarily due 

to lower volumes.

Other  segment  costs  and  expenses  increased  primarily  due  to  $89  million  higher  operating  costs,  primarily 
associated with Transco pipeline integrity testing and general maintenance, a $17 million increase in expense associated 
with an annual revision to the ARO liability, $9 million of higher general and administrative costs due to an increased 
share of allocated support costs, and a $15 million expense in 2017 related to a settlement charge from a pension early 
payout program (see Note 10 – Employee Benefit Plans of Notes to Consolidated Financial Statements). These increases 
are partially offset by a $14 million favorable change in equity AFUDC associated with an increase in Transco’s capital 
spending, which is offset by an $8 million decrease in Constitution’s equity AFUDC. Other favorable changes include 
$12 million lower project development costs at Constitution and favorable impacts related to gains on asset retirements.

Regulatory charges resulting from Tax Reform reflects $493 million of regulatory charges associated with the 
impact of Tax Reform at Transco (See Note 1 – General, Description of Business, Basis of Presentation, and Summary 
of Significant Accounting Policies of Notes to Consolidated Financial Statements).

The decrease in Proportional Modified EBITDA of equity-method investments includes a $12 million decrease 
from Discovery, a $7 million decrease in Cardinal Pipeline Company, LLC and a $5 million decrease in Pine Needle 
LNG Company, LLC.  The decrease in Discovery is primarily associated with lower fee revenue driven by significant 
production issues at certain wells, higher turbine maintenance expenses, temporary hurricane-related shut-ins, and 
maintenance on the Keathley Canyon connector pipeline. The decrease in Cardinal Pipeline Company, LLC and Pine 
Needle LNG Company, LLC is primarily due to $11 million of regulatory charges associated with the impact of Tax 
Reform.

2018 vs. 2017

West Modified EBITDA decreased primarily due to the increase in Impairment of certain assets and lower Service 
revenues. These decreases were partially offset by the  Gain on sale of certain assets in 2018, the absence of regulatory 
charges associated with the impact of Tax Reform, and higher NGL margins driven by higher NGL prices and lower 
realized natural gas prices, partially offset by lower NGL volumes.

Service revenues decreased primarily due to:

•  A $64 million decrease primarily associated with implementing the new revenue guidance under ASC 606 
including a $118 million decrease related to lower amortization of deferred revenue associated with the up-
front cash payments received in conjunction with the fourth quarter 2016 Barnett Shale and Mid-Continent 
contract restructurings, partially offset by a $54 million increase related to other deferred revenue amortization 
primarily in the Permian basin;

•  A $42 million decrease associated with the sale of our Four Corners area assets in October 2018;

•  A $30 million decrease at Northwest Pipeline primarily due to the reduction of its rates as a result of a rate 

case settlement that became effective January 1, 2018;

•  A $29 million decrease following the Jackalope deconsolidation in second quarter 2018;

•  A $15 million decrease driven by lower gathering volumes primarily in the Eagle Ford Shale, Barnett Shale,  
and  Mid-Continent  regions,  partially  offset  by  higher  volumes  in  the  Niobrara  (prior  to  the  Jackalope 
deconsolidation), Piceance, and Permian regions;

•  A $21 million increase associated with higher gathering and processing rates in the Piceance region  driven 
by higher NGL prices as well as higher average gathering and processing rates across most other areas, partially 
offset by lower contract rates primarily in the Haynesville Shale region.

Service revenues – commodity consideration increased as a result of implementing ASC 606 using a modified 
retrospective approach. These revenues represent consideration we receive in the form of commodities as full or partial 

61

payment for gathering and processing services provided. Most of these NGL volumes are sold within the month processed 
and therefore are offset in Product costs below.

The increase in Product sales includes:

•  A $373 million increase in marketing revenues primarily due to increases in realized NGL prices including a 
14 percent increase in average non-ethane per-unit sales prices and a 25 percent increase in ethane prices, in 
addition to a 15 percent increase in ethane volumes (more than offset by higher Product costs);

•  A $47 million increase associated with sales of our equity NGLs, as further described below as part of our 

commodity product margins;

•  An $18 million increase in system management gas sales due to a change in presentation in accordance with 
ASC 606, which are more than offset in Product costs and, therefore, have little impact on Modified EBITDA.

The increase in Product costs includes the impact of ASC 606 in which costs reflected in this line item for 2018 
include volumes acquired as commodity consideration for NGL processing services, a $381 million increase in marketing 
purchases (substantially offset in Product sales), a $19 million increase in system management gas costs (substantially 
offset in Product sales), partially offset by the absence of natural gas purchases associated with the production of equity 
NGLs, which are now reported in Processing commodity expenses in conjunction with the implementation of ASC 606.

Processing commodity expenses presents the natural gas purchases associated with the production of equity NGLs 

as previously described in conjunction with the implementation of ASC 606.

The  net  sum  of  Service  revenues  –  commodity  consideration,  Product  sales,  Product  costs,  and  Processing 
commodity expenses comprise our commodity product margins. Our commodity product margins increased primarily 
due to a $40 million increase in NGL product margins partially offset by an $8 million decrease in marketing margins. 
NGL margins are driven by $56 million in higher ethane and non-ethane per-unit prices, reflecting 19 percent higher 
realized non-ethane per-unit sales prices and 50 percent higher realized ethane per-unit sales prices. These increases 
were partially offset by $18 million in lower volumes primarily due to the sale of our Four Corners area assets in October 
2018.

Other segment costs and expenses decreased primarily due to $57 million lower operating and maintenance and 
general and administrative costs. This reduction in costs is due primarily to the Four Corners area sale in October 2018, 
ongoing cost containment efforts, and the deconsolidation of our Jackalope interest in second quarter 2018. These 
reductions are partially offset by a $24 million regulatory charge associated with Northwest Pipeline’s approved rates 
related to Tax Reform, the absence of a $15 million gain from contract settlements and terminations in 2017, and a $12 
million charge for a regulatory liability associated with a decrease in Northwest Pipeline’s estimated deferred state 
income tax rate following the WPZ Merger.

Impairment of certain assets increased primarily due to the $1.849 billion impairment of certain assets in the 
Barnett Shale region in 2018, partially offset by the absence of a $1.019 billion impairment of certain gathering operations 
in the Mid-Continent region in 2017 (see Note 17 – Fair Value Measurements, Guarantees, and Concentration of Credit 
Risk of Notes to Consolidated Financial Statements).

Gain on sale of certain assets reflects a gain from the sale of our Four Corners area assets in fourth quarter 2018.

Regulatory charges resulting from Tax Reform decreased primarily due to the absence of the $220 million initial 
regulatory charge associated with the impact of Tax Reform at Northwest Pipeline (see Note 1 – General, Description 
of Business, Basis of Presentation, and Summary of Significant Accounting Policies of Notes to Consolidated Financial 
Statements).

Proportional Modified EBITDA of equity-method investments increased primarily due to the deconsolidation of 
our Jackalope interest, which is accounted for as an equity-method investment beginning in the second quarter of 2018.

62

2017 vs. 2016

West  Modified  EBITDA  decreased  primarily  due  to  higher  Impairment  of  certain  assets,  regulatory  charges 
associated with the impact of Tax Reform at Northwest Pipeline, lower gathering rates, and lower volumes as a result 
of natural declines, partially offset by lower segment costs and expenses, higher per-unit NGL margins, and higher 
amortization of deferred revenue associated with the up-front cash payment received in conjunction with the fourth 
quarter 2016 Barnett Shale contract restructuring.

Service revenues decreased primarily due to:

•  A $79 million decrease related to net lower gathering rates, primarily in the Barnett Shale area primarily due 
to the fourth quarter 2016 contract restructuring, as well as lower rates recognized in the Niobrara, Eagle Ford 
Shale, and Haynesville Shale regions. These rate decreases are offset by higher commodity-based fee revenues 
in the Piceance area primarily due to higher per-unit NGL margins and higher rates in the Wamsutter area as 
a result of renegotiated rates in conjunction with infrastructure expansions. Rates recognized in the Niobrara 
region represent a portion of the total contractual rate that is received, with the difference reflected as deferred 
revenue;

•  A $34 million decrease driven by lower volumes in most gathering and processing regions primarily as a result 
of natural declines and more extreme weather conditions in the Rocky Mountains in the first quarter of 2017, 
partially offset by higher volumes in the Haynesville Shale region as a result of increased drilling in certain 
areas;

•  A $39 million increase related to the rate of amortization of deferred revenue associated with the up-front cash 

payment received in conjunction with the fourth quarter 2016 Barnett Shale contract restructuring.

Product sales increased primarily due to:

•  A $532 million increase in marketing revenues primarily due to a $450 million increase driven by higher prices 
and an $82 million increase driven by higher volumes. The average non-ethane per-unit sales price increased 
by 43 percent, the average ethane per-unit sales prices increased by 30 percent, and the average natural gas 
per-unit sales price increased by 13 percent. Ethane and non-ethane sales volumes were 28 percent and six 
percent higher, respectively, partially offset by 17 percent lower natural gas sales volumes.  (Higher marketing 
sales revenues are substantially offset by higher Product costs);

•  A $72 million increase in revenues associated with our equity NGLs primarily due to an $80 million increase 
driven by higher prices, partially offset by an $8 million decrease driven by lower volumes. Realized non-
ethane prices increased by 42 percent and realized ethane prices increased by 46 percent. Non-ethane volumes 
decreased by six percent primarily due to natural declines and to severe winter conditions in the first quarter 
of 2017;

•  A $24 million increase in other product sales related to certain fabricated equipment sales to affiliates (more 

than offset by higher other Product costs).

Product costs increased primarily due to:

•  A $529 million increase in marketing purchases (more than offset in Product sales);

•  A $30 million increase in natural gas purchases associated with the production of equity NGLs primarily due 

to a 26 percent increase in per-unit natural gas prices;

•  A $25 million increase in other product costs related to certain fabricated equipment sales to affiliates (offset 

by higher other Product sales).

63

The decrease in Other segment costs and expenses reflects a $56 million decline in operating expenses, a $27 
million  reduction  in  general  and  administrative  expenses,  and  $15  million  of  gains  from  contract  settlements  and 
terminations in Other (income) expense – net within Operating income (loss). The reductions in operating and general 
and administrative expenses are primarily due to the 2016 workforce reductions, ongoing cost containment efforts, 
lower compression expenses, favorable system gains and gas imbalance revaluations, and a reduced share of allocated 
support costs. These items are partially offset by a $13 million expense in 2017 related to a settlement charge from a 
pension early payout program (See Note 10 – Employee Benefit Plans of Notes to Consolidated Financial Statements).

Impairment of certain assets increased primarily due to the $1.032 billion impairment of certain gathering operations 
primarily in the Mid-Continent region in 2017, partially offset by the absence of $100 million in impairments of certain 
Mid-Continent gathering assets and impairments or write-downs of other certain assets that may no longer be in use 
or are surplus in nature in 2016.

Regulatory charges resulting from Tax Reform reflects $220 million of regulatory charges associated with the 
impact of Tax Reform at Northwest Pipeline (See Note 1 – General, Description of Business, Basis of Presentation, 
and Summary of Significant Accounting Policies of Notes to Consolidated Financial Statements).

Proportional Modified EBITDA of equity-method investments decreased primarily due to the divestiture of our 

interests of DBJV and Ranch Westex LLC late in the first quarter of 2017.

2018 vs. 2017

Modified EBITDA changed unfavorably primarily due to:

•  The absence of a $1.095 billion gain on the sale of our Geismar Interest in 2017 (see Note 3 – Divestitures of 

Notes to Consolidated Financial Statements);

•  The absence of $54 million of Modified EBITDA associated with the results of our former Geismar Olefins 

and RGP Splitter plants subsequent to their sale in July 2017;

•  A $35 million charge in 2018 associated with a charitable contribution of preferred stock to The Williams 
Companies Foundation, Inc. (a not-for-profit corporation) (see Note 15 – Stockholders' Equity of Notes to 
Consolidated Financial Statements);

•  A $34 million decrease due to the absence of a net gain on early retirement of debt in 2017 and a loss on early 
retirement of debt in 2018 (see Note 7 – Other Income and Expenses of Notes to Consolidated Financial 
Statements);

•  A $26 million decrease in income associated with a regulatory asset related to deferred taxes on equity funds 

used during construction;

• 

$20 million in costs in 2018 associated with the WPZ Merger (see Note 1 – General, Description of Business, 
Basis of Presentation, and Summary of Significant Accounting Policies of Notes to Consolidated Financial

•  The absence of a $12 million gain on the sale of the Refinery Grade Propylene Splitter in 2017 (see Note 7 – 

Other Income and Expenses of Notes to Consolidated Financial Statements).

64

 
 
 
These decreases were partially offset by:

•  The absence of a $68 million impairment for a certain NGL pipeline asset in the third quarter of 2017 and a
$23 million impairment of an olefins pipeline project in the Gulf Coast region in the second quarter of 2017, 
partially offset by a $66 million impairment of certain idle pipelines in the second quarter of 2018  (see Note 
17  –  Fair  Value  Measurements,  Guarantees,  and  Concentration  of  Credit  Risk  of  Notes  to  Consolidated 
Financial Statements);

•  A decrease of $62 million for charges reducing regulatory assets related to deferred taxes on AFUDC resulting 
from Tax Reform (see Note 7 – Other Income and Expenses of Notes to Consolidated Financial Statements); 

• 

$40 million of lower costs, driven by the absence of expenses associated with severance and related costs, 
Financial Repositioning, and strategic alternative costs (see Note 1 – General, Description of Business, Basis 
of  Presentation,  and  Summary  of  Significant  Accounting  Policies  of  Notes  to  Consolidated  Financial 
Statements);

•  A $37 million increase associated with the benefit of establishing a regulatory asset associated with an increase 

in Transco’s estimated deferred state income tax rate following the WPZ Merger;

•  A $30 million favorable change in the settlement charge expense related to the program to pay out certain 
deferred vested pension benefits of employees associated with former operations (see Note 10 – Employee 
Benefit Plans of Notes to Consolidated Financial Statements);

•  A $20 million gain on the sale of certain assets and operations located in the Gulf Coast area (see Note 3 – 

Divestitures of Notes to Consolidated Financial Statements).

2017 vs. 2016 

The favorable change in Modified EBITDA is primarily due to:

•  A $1.095 billion gain recognized on the sale of our Geismar Interest in July 2017. (See Note 3 – Divestitures

of Notes to Consolidated Financial Statements);

•  The absence of the $747 million 2016 impairment of our Canadian operations, partially offset by the $23 
million impairment of an olefins pipeline project in the Gulf Coast region in the second quarter of 2017 and 
the $68 million impairment of a certain NGL pipeline asset in the third quarter of 2017 (see Note 17 – Fair 
Value  Measurements,  Guarantees,  and  Concentration  of  Credit  Risk  of  Notes  to  Consolidated  Financial 
Statements);

•  The absence of $61 million of certain project development costs associated with the Canadian PDH facility 

that we expensed in 2016; 

•  A $65 million favorable change in the loss on the sale of our Canadian operations in September 2016;

•  A $38 million decrease in costs related to our evaluation of strategic alternatives;

•  The absence of $32 million of transportation and fractionation fees incurred in 2016 related to the Redwater 

fractionation facility, which was included in the sale of our Canadian operations in September 2016;

•  A $29 million increase in income associated with an increase in a regulatory asset primarily driven by our 

increased ownership in WPZ.

65

These favorable changes are partially offset by:

•  A $164 million decrease due to the absence of results from our former Geismar Olefins and RGP Splitter 

plants subsequent to their sale in July 2017;

•  A $63 million charge reducing regulatory assets related to deferred taxes on AFUDC resulting from Tax Reform 

(see Note 7 – Other Income and Expenses of Notes to Consolidated Financial Statements);

•  A $35 million settlement charge expense related to the program to pay out certain deferred vested pension 
benefits of employees associated with former operations. (See Note 10 – Employee Benefit Plans of Notes to 
Consolidated Financial Statements);

•  A reduction in revenues associated with an NGL pipeline near the Houston Ship Channel region;

•  The absence of a $10 million gain on the sale of unused pipe in 2016.

Management’s Discussion and Analysis of Financial Condition and Liquidity

Overview

In 2018, through the WPZ Merger, we streamlined our corporate structure and governance while improving our 
credit ratings to investment-grade. Additionally, we monetized assets, through sales of the Four Corners area assets and 
certain Gulf Coast pipeline systems which were not core to our business strategy, into a source for growth capital for 
acquisitions such as our RMM equity-method investment and a driver for improving credit metrics while continuing 
to reduce our direct commodity exposure.

Outlook

Fee-based businesses are a significant component of our portfolio and serve to reduce the influence of commodity 
price fluctuations on our cash flows. We expect to benefit as continued growth in demand for low-cost natural gas is 
driven by increases in LNG exports, industrial demand, and power generation.

As previously discussed in Company Outlook, our consolidated growth capital and investment expenditures in 
2019 are currently expected to be in a range from $2.7 billion to $2.9 billion. Growth capital spending in 2019 includes 
Transco expansions, all of which are fully contracted with firm transportation agreements, and continuing to develop 
our gathering and processing infrastructure in the Northeast G&P and West segments. In addition to growth capital and 
investment expenditures, we also remain committed to projects that maintain our assets for safe and reliable operations, 
as well as projects that meet legal, regulatory, and/or contractual commitments. We intend to fund our planned 2019 
growth capital with retained cash flow and certain sources of available liquidity described below. We retain the flexibility 
to adjust planned levels of growth capital and investment expenditures in response to changes in economic conditions 
or business opportunities.

Liquidity

Based on our forecasted levels of cash flow from operations and other sources of liquidity, we expect to have 
sufficient liquidity to manage our businesses in 2019. Our potential material internal and external sources and uses of 
consolidated liquidity for 2019 are as follows:

Sources:

Uses:

Cash and cash equivalents on hand
Cash generated from operations
Distributions from our equity-method investees
Utilization of our credit facility and/or commercial paper program
Cash proceeds from issuance of debt and/or equity securities
Proceeds from asset monetizations

Working capital requirements
Capital and investment expenditures
Quarterly dividends to our shareholders
Debt service payments, including payments of long-term debt

Potential risks associated with our planned levels of liquidity discussed above include those previously discussed 

in Company Outlook.

67

As of December 31, 2018, we had a working capital deficit of $347 million, including cash and cash equivalents. 

Our available liquidity is as follows:

__________
(1)  In managing our available liquidity, we do not expect a maximum outstanding amount in excess of the capacity 
of  our  credit  facility  inclusive  of  any  outstanding  amounts  under  our  commercial  paper  program.  Through 
completion  of  the WPZ  Merger  on August  10,  2018,  the  highest  combined  amount  outstanding  under WPZ’s 
commercial paper program and credit facility and our former credit facility during 2018 was $1.325 billion. In 
July 2018, we along with Transco and Northwest Pipeline entered into a new unsecured revolving credit agreement 
with  aggregate  commitments  available  of  $4.5  billion  under  the  credit  facility,  which  became  effective  upon 
completion of the WPZ Merger. The highest amount outstanding under our current commercial paper program and 
credit facility during 2018 was $886 million. At December 31, 2018, we were in compliance with the financial 
covenants associated with our credit facility. See Note 14 – Debt, Banking Arrangements, and Leases of Notes to 
Consolidated Financial Statements for additional information on our credit facility and commercial paper program. 
Borrowing capacity available under our credit facility as of February 19, 2019, was $4.5 billion.

Dividends

We increased our regular quarterly cash dividend by approximately 13 percent from the previous quarterly cash 
dividends of $0.30 per share paid in each quarter of 2017, to $0.34 per share for the quarterly cash dividends paid in 
each quarter of 2018.

Registrations

In February 2018, we filed a shelf registration statement, as a well-known seasoned issuer. In August 2018, we 
filed a prospectus supplement for the offer and sale from time to time of shares of our common stock having an aggregate 
offering price of up to $1 billion. These sales are to be made over a period of time and from time to time in transactions 
at then-current prices. Such sales are to be made pursuant to an equity distribution agreement between us and certain 
entities who may act as sales agents or purchase for their own accounts as principals at a price agreed upon at the time 
of the sale. There was no activity during 2018.

Distributions from Equity-Method Investees

The  organizational  documents  of  entities  in  which  we  have  an  equity-method  investment  generally  require 
distribution of their available cash to their members on a quarterly basis. In each case, available cash is reduced, in 
part, by reserves appropriate for operating their respective businesses. (See Note 6 – Investing Activities of Notes to 
Consolidated Financial Statements for our more significant equity-method investees.)

Credit Ratings

The interest rates at which we are able to borrow money is impacted by our credit ratings. The current ratings are 

as follows:

Rating Agency

S&P Global Ratings
Moody’s Investors Service
Fitch Ratings

Outlook
Negative
Stable
Positive

Senior Unsecured
Debt Rating
BBB
Baa3
BBB-

Corporate
Credit Rating

68

 
These credit ratings are included for informational purposes and are not recommendations to buy, sell, or hold our 
securities, and each rating should be evaluated independently of any other rating. No assurance can be given that the 
credit rating agencies will continue to assign us investment-grade ratings even if we meet or exceed their current criteria 
for investment-grade ratios. A downgrade of our credit ratings might increase our future cost of borrowing and would 
require us to provide additional collateral to third parties, negatively impacting our available liquidity.

Operating activities

The factors that determine operating activities are largely the same as those that affect Net income (loss), with the 
exception of noncash items such as Depreciation and amortization, Provision (benefit) for deferred income taxes, Equity 
(earnings) losses, Net (gain) loss on disposition of equity-method investments, Impairment of equity-method investments, 
Gain on sale of certain assets, Impairment of and net (gain) loss on sale of other assets and businesses, Gain on 
deconsolidation of businesses, and Regulatory charges resulting from Tax Reform.

Our Net cash provided (used) by operating activities in 2018 increased from 2017 primarily due to higher operating 
income  (excluding  noncash  items  as  previously  discussed)  in  2018,  partially  offset  by  the  impact  of  decreased 
distributions from unconsolidated affiliates in 2018.

Our Net cash provided (used) by operating activities in 2017 decreased from 2016 primarily due to the absence in 
2017  of  receipts  from  2016  contract  restructurings,  partially  offset  by  higher  operating  income  and  increased 
distributions from unconsolidated affiliates in 2017.

Off-Balance Sheet Arrangements and Guarantees of Debt or Other Commitments

We have various other guarantees and commitments which are disclosed in Note 4 – Variable Interest Entities, 
Note 11 – Property, Plant, and Equipment, Note 14 – Debt, Banking Arrangements, and Leases, Note 17 – Fair Value 
Measurements, Guarantees, and Concentration of Credit Risk, and Note 18 – Contingent Liabilities and Commitments
of Notes to Consolidated Financial Statements. We do not believe these guarantees and commitments or the possible 
fulfillment of them will prevent us from meeting our liquidity needs.

______________
(1)  Includes the borrowings outstanding under credit facilities, but does not include any related variable-rate interest 

payments.

(2)  Includes approximately $480 million in open property, plant, and equipment purchase orders. Includes an estimated 
$329 million long-term ethane purchase obligation with index-based pricing terms that is reflected in this table at 
December 31, 2018 prices. This obligation is part of an overall exchange agreement whereby volumes we transport 
on OPPL are sold at a third-party fractionator near Conway, Kansas, and we are subsequently obligated to purchase 
ethane volumes at Mont Belvieu. The purchased ethane volumes may be utilized or sold at comparable prices in 
the Mont Belvieu market. Includes an estimated $453 million long-term ethane purchase obligation with index-
based pricing terms that primarily supplies third parties at their plants and is reflected in this table at a value 
calculated using December 31, 2018 prices. Any excess purchased volumes may be sold at comparable market 
prices. Includes an estimated $211 million long-term mixed NGLs purchase obligation with index-based pricing 
terms that is reflected in this table at December 31, 2018 prices. Includes an estimated $312 million long-term 
ethane purchase obligation with index-based pricing terms that primarily supplies a third party for consumption 
at their plant and is reflected in this table at a value calculated using December 31, 2018 prices. Any excess purchased 
volumes may be sold at comparable market prices. Includes an estimated $332 million long-term mixed NGLs 
purchase obligation with index-based pricing terms that is reflected in this table at December 31, 2018 prices. In 
addition,  we  have  not  included  certain  natural  gas  life-of-lease  contracts  for  which  the  future  volumes  are 
indeterminable. We have not included commitments, beyond purchase orders, for the acquisition or construction 
of  property,  plant,  and  equipment  or  expected  contributions  to  our  jointly  owned  investments.  (See  Company 
Outlook — Expansion Projects.)

(3)  Does  not  include  estimated  contributions  to  our  pension  and  other  postretirement  benefit  plans.  We  made 
contributions to our pension and other postretirement benefit plans of $93 million in 2018 and $90 million in 2017. 
In 2019, we expect to contribute approximately $69 million to these plans (see Note 10 – Employee Benefit Plans
of  Notes  to  Consolidated  Financial  Statements).  Tax-qualified  pension  plans  are  required  to  meet  minimum 
contribution requirements. In the past, we have contributed amounts to our tax-qualified pension plans in excess 
of the minimum required contribution. These excess amounts can be used to offset future minimum contribution 
requirements. During 2018, we contributed $80 million to our tax-qualified pension plans. In addition to these 
contributions, a portion of the excess contributions was used to meet the minimum contribution requirements. 
During 2019, we expect to contribute approximately $60 million to our tax-qualified pension plans and use excess 
amounts to satisfy minimum contribution requirements, if needed. Additionally, estimated future minimum funding 
requirements may vary significantly from historical requirements if actual results differ significantly from estimated 

70

 
 
 
 
 
results for assumptions such as returns on plan assets, interest rates, retirement rates, mortality, and other significant 
assumptions or by changes to current legislation and regulations.

(4)  We have not included income tax liabilities in the table above. See Note 8 – Provision (Benefit) for Income Taxes 
of  Notes  to  Consolidated  Financial  Statements  for  a  discussion  of  income  taxes,  including  our  contingent  tax 
liability reserves.

Effects of Inflation

Our operations have historically not been materially affected by inflation. Approximately 50 percent of our gross 
property, plant, and equipment is comprised of our interstate natural gas pipeline assets. They are subject to regulation, 
which limits recovery to historical cost. While amounts in excess of historical cost are not recoverable under current 
FERC practices, we anticipate being allowed to recover and earn a return based on increased actual cost incurred to 
replace existing assets. Cost-based regulations, along with competition and other market factors, may limit our ability 
to recover such increased costs. For our gathering and processing assets, operating costs are influenced to a greater 
extent by both competition for specialized services and specific price changes in crude oil and natural gas and related 
commodities than by changes in general inflation. Crude oil, natural gas, and NGL prices are particularly sensitive to 
the market perceptions concerning the supply and demand balance in the near future, as well as general economic 
conditions. However, our exposure to certain of these price changes is reduced through the fee-based nature of certain 
of our services and the use of hedging instruments.

Environmental

We are a participant in certain environmental activities in various stages including assessment studies, cleanup 
operations, and/or remedial processes at certain sites, some of which we currently do not own (see Note 18 – Contingent 
Liabilities  and  Commitments  of  Notes  to  Consolidated  Financial  Statements).  We  are  monitoring  these  sites  in  a 
coordinated effort with other potentially responsible parties, the EPA, or other governmental authorities. We are jointly 
and severally liable along with unrelated third parties in some of these activities and solely responsible in others. Current 
estimates of the most likely costs of such activities are approximately $35 million, all of which are included in Accrued 
liabilities and Regulatory liabilities, deferred income, and other in the Consolidated Balance Sheet at December 31, 
2018. We will seek recovery of the accrued costs related to remediation activities by our interstate gas pipelines totaling 
approximately $6 million through future natural gas transmission rates. The remainder of these costs will be funded 
from  operations.  During  2018,  we  paid  approximately  $4  million  for  cleanup  and/or  remediation  and  monitoring 
activities. We expect to pay approximately $11 million in 2019 for these activities. Estimates of the most likely costs 
of cleanup are generally based on completed assessment studies, preliminary results of studies, or our experience with 
other similar cleanup operations. At December 31, 2018, certain assessment studies were still in process for which the 
ultimate outcome may yield different estimates of most likely costs. Therefore, the actual costs incurred will depend 
on the final amount, type, and extent of contamination discovered at these sites, the final cleanup standards mandated 
by the EPA or other governmental authorities, and other factors.

The EPA and various state regulatory agencies routinely promulgate and propose new rules and issue updated 
guidance to existing rules. These rulemakings include, but are not limited to, rules for reciprocating internal combustion 
engine maximum achievable control technology, air quality standards for one-hour nitrogen dioxide emissions, and 
volatile organic compound and methane new source performance standards impacting design and operation of storage 
vessels, pressure valves, and compressors. The EPA previously issued its rule regarding National Ambient Air Quality 
Standards for ground-level ozone. We are monitoring the rule's implementation as it will trigger additional federal and 
state regulatory actions that may impact our operations. Implementation of the regulations is expected to result in 
impacts to our operations and increase the cost of additions to Property, plant, and equipment – net in the Consolidated 
Balance Sheet for both new and existing facilities in affected areas. We are unable to reasonably estimate the cost of 
additions that may be required to meet the regulations at this time due to uncertainty created by various legal challenges 
to these regulations and the need for further specific regulatory guidance.

Our interstate natural gas pipelines consider prudently incurred environmental assessment and remediation costs 

and the costs associated with compliance with environmental standards to be recoverable through rates.

Item 7A.  Quantitative and Qualitative Disclosures About Market Risk

Interest Rate Risk

Our current interest rate risk exposure is related primarily to our debt portfolio. Our debt portfolio is primarily 
comprised of fixed rate debt, which mitigates the impact of fluctuations in interest rates. Any borrowings under our 
credit facility and any issuances under our commercial paper program could be at a variable interest rate and could 
expose us to the risk of increasing interest rates. The maturity of our long-term debt portfolio is partially influenced by 
the  expected  lives  of  our  operating  assets.  (See  Note  14  –  Debt,  Banking Arrangements,  and  Leases  of  Notes  to 
Consolidated Financial Statements.)

The tables below provide information by maturity date about our interest rate risk-sensitive instruments as of 
December 31, 2018 and 2017. See Note 17 – Fair Value Measurements, Guarantees, and Concentration of Credit Risk
of Notes to Consolidated Financial Statements for the methods used in determining the fair value of our long-term debt.

Commodity Price Risk

We are exposed to the impact of fluctuations in the market price of NGLs and natural gas, as well as other market 
factors, such as market volatility and energy commodity price correlations. We are exposed to these risks in connection 
with our owned energy-related assets, our long-term energy-related contracts, and limited proprietary trading activities. 
Our management of the risks associated with these market fluctuations includes maintaining sufficient liquidity, as well 
as using various derivatives and nonderivative energy-related contracts. The fair value of derivative contracts is subject 
to many factors, including changes in energy commodity market prices, the liquidity and volatility of the markets in 
which the contracts are transacted, and changes in interest rates. At December 31, 2018 and 2017, our derivative activity 
was not material. (See Note 17 – Fair Value Measurements, Guarantees, and Concentration of Credit Risk of Notes to 
Consolidated Financial Statements.)

Item 8.  Financial Statements and Supplementary Data 

Report of Independent Registered Public Accounting Firm

The Stockholders and the Board of Directors of
The Williams Companies, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheet of The Williams Companies, Inc. (the Company) as of 
December 31, 2018 and 2017, the related consolidated statements of operations, comprehensive income (loss), changes 
in equity and cash flows for each of the three years in the period ended December 31, 2018, and the related notes and 
the financial statement schedule listed in the index at Item 15(a) (collectively referred to as the “consolidated financial 
statements”).  In our opinion, based on our audits and the reports of other auditors, the consolidated financial statements 
present fairly, in all material respects, the consolidated financial position of the Company at December 31, 2018 and 
2017, and the consolidated results of its operations and its cash flows for each of the three years in the period ended 
December 31, 2018, in conformity with U.S. generally accepted accounting principles. 

We did not audit the financial statements of Gulfstream Natural Gas System, L.L.C. (Gulfstream), a limited liability 
corporation in which the Company has a 50 percent interest. In the consolidated financial statements, the Company’s 
investment in Gulfstream was $225 million and $244 million as of December 31, 2018 and 2017, respectively, and the 
Company’s equity earnings in the net income of Gulfstream were $75 million in 2018, $75 million in 2017 and $69 
million in 2016.  Gulfstream’s financial statements were audited by other auditors whose reports have been furnished 
to us, and our opinion, insofar as it relates to the amounts included for Gulfstream, is based solely on the reports of the 
other auditors.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United 
States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2018, based on criteria 
established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the 
Treadway Commission (2013 framework) and our report dated February 21, 2019 expressed an unqualified opinion 
thereon.

Adoption of New Accounting Standards

As discussed in Note 1 and Note 2 to the consolidated financial statements, the Company changed its method for 
accounting for revenue in 2018.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company's management. Our responsibility is to 
express an opinion on the Company’s consolidated financial statements based on our audits. We are a public accounting 
firm registered with the PCAOB and are required to be independent with respect to the 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 consolidated financial statements are free of material 
misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material 
misstatement of the consolidated 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 consolidated 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  consolidated 
financial statements. We believe that our audits and the reports of other auditors provide a reasonable basis for our 
opinion.

Report of Independent Registered Public Accounting Firm

To the Members of Gulfstream Natural Gas System, L.L.C.   

We have audited the statement of operations, comprehensive income, cash flows, and members’ equity of Gulfstream 
Natural Gas System, L.L.C. (the "Company") for the period ended December 31, 2016. These financial statements are 
the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements 
based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United 
States) and in accordance with auditing standards generally accepted in the United States of America. Those standards 
require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are 
free of material misstatement. The Company is not required to have, nor were we engaged to perform, an audit of its 
internal control over financial reporting. Our audit included consideration of internal control over financial reporting 
as a basis for designing audit procedures that are appropriate in the circumstances, 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. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in 
the financial statements, assessing the accounting principles used and significant estimates made by management, as 
well as evaluating the overall financial statement presentation. We believe that our audit provides a reasonable basis 
for our opinion.

In our opinion, such financial statements present fairly, in all material respects, the results of operations of Gulfstream 
Natural Gas System, L.L.C. and its cash flows for the period ended December 31, 2016, in conformity with accounting 
principles generally accepted in the United States of America.

The Williams Companies, Inc.
Notes to Consolidated Financial Statements

Note 1 – General, Description of Business, Basis of Presentation, and Summary of Significant Accounting Policies

General

Unless the context clearly indicates otherwise, references in this report to “Williams,” “we,” “our,” “us,” or like 
terms  refer  to  The  Williams  Companies,  Inc.  and  its  subsidiaries.  Unless  the  context  clearly  indicates  otherwise, 
references to “Williams,” “we,” “our,” and “us” include the operations in which we own interests accounted for as 
equity-method investments that are not consolidated in our financial statements. When we refer to our equity investees 
by name, we are referring exclusively to their businesses and operations.

WPZ Merger

On August 10, 2018, we completed our merger with Williams Partners L.P. (WPZ), our previously consolidated 
master limited partnership, pursuant to which we acquired all of the approximately 256 million publicly held outstanding 
common units of WPZ in exchange for 382 million shares of our common stock (WPZ Merger). Williams continued 
as the surviving entity. The WPZ Merger was accounted for as a noncash equity transaction resulting in increases to 
Common stock of $382 million, Capital in excess of par value of $6.112 billion, and Regulatory assets, deferred charges, 
and other of $33 million and decreases to Accumulated other comprehensive income (loss) (AOCI) of $3 million, 
Noncontrolling interests in consolidated subsidiaries of $4.629 billion, and Deferred income tax liabilities of $1.829 
billion in the Consolidated Balance Sheet. Prior to the completion of the WPZ Merger and pursuant to its distribution 
reinvestment program, WPZ had issued common units to the public in 2018, 2017, and 2016 associated with reinvested 
distributions of $46 million, $61 million, and $10 million, respectively.

Financial Repositioning

In January 2017, we entered into agreements with WPZ, wherein we permanently waived the general partner’s 
incentive distribution rights and converted our 2 percent general partner interest in WPZ to a noneconomic interest in 
exchange  for  289  million  newly  issued  WPZ  common  units.  Pursuant  to  this  agreement,  we  also  purchased 
approximately 277 thousand WPZ common units for $10 million. Additionally, we purchased approximately 59 million
common units of WPZ at a price of $36.08586 per unit in a private placement transaction, funded with proceeds from 
our equity offering (see Note 15 – Stockholders' Equity). According to the terms of this agreement, concurrent with 
WPZ’s quarterly distributions in February 2017 and May 2017, we paid additional consideration totaling $56 million 
to WPZ for these units.

Description of Business

We are a Delaware corporation whose common stock is listed and traded on the New York Stock Exchange. Our 
operations are located in the United States. Prior to the WPZ Merger, we had one reportable segment, Williams Partners. 
Beginning in the third-quarter 2018, consistent with the manner in which our chief operating decision maker evaluates 
performance  and  allocates  resources,  our  operations  are  now  presented  within  the  following  reportable  segments: 
Northeast  G&P, Atlantic-Gulf,  and  West.  Prior  period  segment  disclosures  have  been  recast  for  the  new  segment 
presentation.

Northeast G&P is comprised of our midstream gathering and processing businesses in the Marcellus Shale region 
primarily in Pennsylvania, New York, and West Virginia and the Utica Shale region of eastern Ohio, as well as a 66 
percent  interest  in  Cardinal  Gas  Services,  L.L.C.  (Cardinal)  (a  consolidated  entity),  a  62  percent  equity-method 
investment in Utica East Ohio Midstream, LLC (UEOM), a 69 percent equity-method investment in Laurel Mountain 
Midstream, LLC (Laurel Mountain), a 58 percent equity-method investment in Caiman Energy II, LLC (Caiman II), 
and Appalachia Midstream Services, LLC, which owns equity-method investments with an approximate average 66 
percent interest in multiple gas gathering systems in the Marcellus Shale (Appalachia Midstream Investments).

Atlantic-Gulf is comprised of our interstate natural gas pipeline, Transcontinental Gas Pipe Line Company, LLC 
(Transco), and significant natural gas gathering and processing and crude oil production handling and transportation 

81

The Williams Companies, Inc.
Notes to Consolidated Financial Statements – (Continued)

assets in the Gulf Coast region, including a 51 percent interest in Gulfstar One LLC (Gulfstar One) (a consolidated 
entity), which is a proprietary floating production system, and various petrochemical and feedstock pipelines in the 
Gulf  Coast  region,  as  well  as  a  50  percent  equity-method  investment  in  Gulfstream  Natural  Gas  System,  L.L.C. 
(Gulfstream), a 60 percent equity-method investment in Discovery Producer Services LLC (Discovery), and a 41 percent
interest in Constitution Pipeline Company, LLC (Constitution) (a consolidated entity), which is developing a pipeline 
project (see Note 4 – Variable Interest Entities).

West is comprised of our interstate natural gas pipeline, Northwest Pipeline LLC (Northwest Pipeline), and our 
gathering, processing, and treating operations in Colorado, Wyoming, and the Barnett Shale region of north-central 
Texas, the Eagle Ford Shale region of south Texas, the Haynesville Shale region of northwest Louisiana, and the Mid-
Continent region which includes the Anadarko, Arkoma, Delaware, and Permian basins. This segment also includes 
our natural gas liquid (NGL) and natural gas marketing business, storage facilities, an undivided 50 percent interest in 
an NGL fractionator near Conway, Kansas, and a 50 percent equity-method investment in Overland Pass Pipeline, LLC 
(OPPL), a 50 percent interest in Jackalope Gas Gathering Services, L.L.C. (Jackalope) (an equity-method investment 
following deconsolidation as of June 30, 2018), a 50 percent equity-method investment in Rocky Mountain Midstream 
Holdings LLC (RMM), a 15 percent equity-method investment in Brazos Permian II, LLC (Brazos Permian II), and 
our previously owned 50 percent equity-method investment in the Delaware basin gas gathering system (DBJV) in the 
Mid-Continent region (see Note 6 – Investing Activities). West also included our former natural gas gathering and 
processing assets in the Four Corners area of New Mexico and Colorado (see Note 3 – Divestitures).

Other includes our previously owned operations, including our former Williams Olefins, L.L.C., a wholly owned 
subsidiary which owned our 88.5 percent undivided interest in the Geismar, Louisiana, olefins plant (Geismar Interest), 
which was sold in July 2017 (see Note 3 – Divestitures), and a refinery grade propylene splitter in the Gulf region, 
which was sold in June 2017. This segment also included our previously owned Canadian assets, which included an 
oil sands offgas processing plant near Fort McMurray, Alberta, and an NGL/olefin fractionation facility at Redwater, 
Alberta. In September 2016, these Canadian operations were sold. Other also includes minor business activities that 
are not operating segments, as well as corporate operations.

Basis of Presentation

Significant risks and uncertainties

We believe that the carrying value of certain of our property, plant, and equipment and other identifiable intangible 
assets, notably certain acquired assets accounted for as business combinations between 2012 and 2014, may be in excess 
of current fair value.  However, the carrying value of these assets, in our judgment, continues to be recoverable based 
on our evaluation of undiscounted future cash flows.  It is reasonably possible that future strategic decisions, including 
transactions such as monetizing non-core assets or contributing assets to new ventures with third parties, as well as 
unfavorable changes in expected producer activities could impact our assumptions and ultimately result in impairments 
of these assets.  Such transactions or developments may also indicate that certain of our equity-method investments 
have experienced other-than-temporary declines in value, which could also result in impairment.

On March 15, 2018, the Federal Energy Regulatory Commission (FERC) issued a revised policy statement (the 
revised policy statement) regarding the recovery of income tax costs in rates of natural gas pipelines. The FERC found 
that an impermissible double recovery results from granting a Master Limited Partnership (MLP) pipeline both an 
income tax allowance and a return on equity pursuant to the discounted cash flow methodology. As a result, the FERC 
will no longer permit an MLP pipeline to recover an income tax allowance in its cost of service. The FERC further 
stated it will address the application of this policy to non-MLP partnership forms as those issues arise in subsequent 
proceedings. One of the benefits of the recent WPZ Merger is to allow our FERC-regulated pipelines to continue to 
recover an income tax allowance in their cost of service rates.

On July 18, 2018, the FERC issued an order dismissing the requests for rehearing and clarification of the revised 
policy statement. In addition, the FERC provided guidance that an MLP pipeline (or other pass-through entity) no 
longer recovering an income tax allowance pursuant to the revised policy may eliminate previously accumulated deferred 

82

The Williams Companies, Inc.
Notes to Consolidated Financial Statements – (Continued)

income taxes (ADIT) from its cost of service instead of flowing these ADIT balances to ratepayers. This guidance, if 
implemented, would significantly mitigate the impact of the revised policy statement. However, the FERC stated that 
the revised policy statement and such guidance do not establish a binding rule but are instead expressions of general 
policy intent designed to provide guidance by notifying entities of the course of action the FERC intends to follow in 
future adjudications. To the extent the FERC addresses these issues in future proceedings, it will consider any arguments 
regarding not only the application of the revised policy to the facts of the case, but also any arguments regarding the 
underlying validity of the policy itself. The FERC’s guidance on ADIT likely will be challenged by customers and state 
commissions, which would result in a long period of revenue uncertainty for pipelines eliminating ADIT from their 
cost of service. The WPZ Merger has the additional benefit of eliminating this uncertainty.

On March 15, 2018, the FERC also issued a Notice of Proposed Rulemaking proposing a filing process that will 
allow it to determine which natural gas pipelines may be collecting unjust and unreasonable rates in light of the recent 
reduction in the corporate income tax rate in the Tax Cuts and Jobs Act (Tax Reform) and the revised policy statement. 
On July 18, 2018, the FERC issued a Final Rule, retaining the filing requirement and reaffirming the options that 
pipelines have to either reflect the reduced tax rate or explain why no rate change is necessary. The FERC also clarified 
that a natural gas company organized as a pass-through entity and all of whose income or losses are consolidated on 
the federal income tax return of its corporate parent is considered to be subject to the federal corporate income tax and 
is thus eligible for a tax allowance. We believe this Final Rule and the previously discussed WPZ Merger allow for the 
continued recovery of income tax allowances in Transco’s and Northwest Pipeline’s rates. Transco’s August 31, 2018 
general rate case filing reflects a tax allowance based on this clarification, and the FERC’s September 28, 2018 order 
in that rate case proceeding finds that Transco is exempt from the Final Rule’s Form 501-G filing requirement. In 
addition, on October 19, 2018, Northwest Pipeline filed a petition requesting that the FERC waive its Form 501-G 
filing requirement under this Final Rule because (i) the reduction in the corporate income tax is already addressed in 
Northwest  Pipeline’s  2017  rate  settlement,  and  (ii)  as  discussed  above,  the WPZ  Merger  allows  for  the  continued 
recovery of income tax allowances in Northwest Pipeline’s rates. The FERC agreed and granted Northwest Pipeline’s 
petition for waiver on November 19, 2018. On October 11, 2018 and December 6, 2018, Discovery Gas Transmission, 
LLC and Pine Needle LNG Company, LLC, respectively, filed their Form 501-Gs, including explanations as to why 
no adjustments to rates are needed.

On March 15, 2018, the FERC also issued a Notice of Inquiry seeking comments on the additional impacts of Tax 
Reform on jurisdictional rates, particularly whether, and if so how, the FERC should address changes relating to ADIT 
amounts after the corporate income tax rate reduction and bonus depreciation rules, as well as whether other features 
of Tax Reform require FERC action. We are evaluating the impact of these developments on our interstate natural gas 
pipelines and currently expect any associated impacts would be prospective and determined through subsequent rate 
proceedings. We also continue to monitor developments that may impact our regulatory liabilities resulting from Tax 
Reform. It is reasonably possible that future tariff-based rates collected by our interstate natural gas pipelines may be 
adversely impacted.

Summary of Significant Accounting Policies

Principles of consolidation

The consolidated financial statements include the accounts of all entities that we control and our proportionate 
interest in the accounts of certain ventures in which we own an undivided interest. Our judgment is required to evaluate 
whether we control an entity. Key areas of that evaluation include:

•  Determining whether an entity is a variable interest entity (VIE);

•  Determining whether we are the primary beneficiary of a VIE, including evaluating which activities of the 
VIE most significantly impact its economic performance and the degree of power that we and our related 
parties have over those activities through our variable interests;

83

The Williams Companies, Inc.
Notes to Consolidated Financial Statements – (Continued)

• 

Identifying events that require reconsideration of whether  an  entity  is a VIE  and  continuously evaluating 
whether we are a VIE’s primary beneficiary;

•  Evaluating whether other owners in entities that are not VIEs are able to effectively participate in significant 
decisions that would be expected to be made in the ordinary course of business such that we do not have the 
power to control such entities.

We apply the equity method of accounting to investments over which we exercise significant influence but do not 

control.

Equity-method investment basis differences

Differences between the cost of our equity-method investments and our underlying equity in the net assets of 
investees  are  accounted  for  as  if  the  investees  were  consolidated  subsidiaries.  Equity  earnings  (losses)  in  the 
Consolidated Statement of Operations includes our allocable share of net income (loss) of investees adjusted for any 
depreciation and amortization, as applicable, associated with basis differences.

Use of estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United 
States requires us to make estimates and assumptions that affect the amounts reported in the consolidated financial 
statements and accompanying notes. Actual results could differ from those estimates.

Significant estimates and assumptions include:

• 

Impairment  assessments  of  investments,  property,  plant,  and  equipment,  and  other  identifiable  intangible 
assets;

•  Litigation-related contingencies;

•  Environmental remediation obligations;

•  Depreciation and/or amortization of long-lived assets;

•  Depreciation and/or amortization of equity-method investment basis differences;

•  Asset retirement obligations (AROs);

•  Pension and postretirement valuation variables;

•  Measurement of regulatory liabilities;

•  Measurement of deferred income tax assets and liabilities, including assumptions related to the realization of 

deferred income tax assets.

These estimates are discussed further throughout these notes.

Regulatory accounting

Transco and Northwest Pipeline are regulated by the FERC. Their rates, which are established by the FERC, are 
designed to recover the costs of providing the regulated services, and their competitive environment makes it probable 
that such rates can be charged and collected. Therefore, we have determined that it is appropriate under Accounting 
Standards Codification (ASC) Topic 980, “Regulated Operations,” (ASC 980) to account for and report regulatory 
assets and liabilities related to these operations consistent with the economic effect of the way in which their rates are 

84

The Williams Companies, Inc.
Notes to Consolidated Financial Statements – (Continued)

established. Accounting  for  these  operations  that  are  regulated  can  differ  from  the  accounting  requirements  for 
nonregulated operations. For example, for regulated operations, allowance for funds used during construction (AFUDC) 
represents the estimated cost of debt and equity funds applicable to utility plant in the process of construction and is 
capitalized  as  a  cost  of  property,  plant,  and  equipment  because  it  constitutes  an  actual  cost  of  construction  under 
established regulatory practices; nonregulated operations are only allowed to capitalize the cost of debt funds related 
to construction activities, while a component for equity is prohibited. The components of our regulatory assets and 
liabilities relate to the effects of deferred taxes on equity funds used during construction, asset retirement obligations, 
fuel cost differentials, levelized incremental depreciation, negative salvage, pension and other postretirement benefits, 
and rate allowances for deferred income taxes at a historically higher federal income tax rate.

In December 2017, Tax Reform was enacted, which, among other things, reduced the federal corporate income 
tax rate from 35 percent to 21 percent (see Note 8 – Provision (Benefit) for Income Taxes). In accordance with ASC 
980-740-25-2, Transco and Northwest Pipeline have recognized regulatory liabilities to reflect the probable return to 
customers through future rates of the future decrease in income taxes payable associated with Tax Reform. These 
liabilities represent an obligation to return amounts directly to our customers. While a majority of our customers have 
entered into tariff rates based on our cost-of-service proceedings and related rate base therein, certain other contracts 
with  customers  reflect  contractually-based  rates  that  are  designed  to  recover  the  cost  of  providing  those  services, 
including an allowance for income taxes, with no expected future rate adjustment for the term of those contracts. This 
relative mix of contracts for services was considered in determining the probable amount to be returned to customers 
through future rates. The regulatory liabilities were recorded in December 2017 through regulatory charges to operating 
income totaling $674 million. As of December 31, 2018, the balance of these regulatory liabilities totaled $657 million. 
The timing and actual amount of such return will be subject to future negotiations regarding this matter and many other 
elements of cost-of-service rate proceedings, including other costs of providing service.

Certain of our equity-method investees recorded similar regulatory liabilities, for which our Equity earnings (losses)
in the Consolidated Statement of Operations for 2017 were reduced by $11 million related to our proportionate share 
of the associated regulatory charges. 

Our regulatory assets associated with the effects of deferred taxes on equity funds used during construction were 
also impacted by Tax Reform and were reduced by $102 million in December 2017 through a charge to Other income 
(expense) – net below Operating income (loss) in the Consolidated Statement of Operations (see Note 7 – Other Income 
and Expenses). This amount, along with the previously described charges for establishing the regulatory liabilities 
resulting from Tax Reform, is reported within Regulatory charges resulting from Tax Reform within the Consolidated 
Statement of Cash Flows.

Our current and noncurrent regulatory asset and liability balances for the years ended December 31, 2018 and 2017 

are as follows:

Cash and cash equivalents

Cash and cash equivalents consist of highly liquid investments with original maturities of three months or less 

when acquired.

Accounts receivable

Accounts receivable are carried on a gross basis, with no discounting, less an allowance for doubtful accounts. We 
estimate the allowance for doubtful accounts based on existing economic conditions, the financial condition of our 
customers, and the amount and age of past due accounts. We do not offer extended payment terms and typically receive 
payment within one month. We consider receivables past due if full payment is not received by the contractual due 
date. Interest income related to past due accounts receivable is generally recognized at the time full payment is received 
or collectability is assured. Past due accounts are generally written off against the allowance for doubtful accounts only 
after all collection attempts have been exhausted.

Inventories

Inventories in the Consolidated Balance Sheet primarily consist of NGLs, natural gas in underground storage, and 
materials and supplies and are stated at the lower of cost or net realizable value. The cost of inventories is primarily 
determined using the average-cost method.

Property, plant, and equipment

Property, plant, and equipment is initially recorded at cost. We base the carrying value of these assets on estimates, 

assumptions, and judgments relative to capitalized costs, useful lives, and salvage values.

As regulated entities, Northwest Pipeline and Transco provide for depreciation using the straight-line method at 
FERC-prescribed rates. Depreciation for nonregulated entities is provided primarily on the straight-line method over 
estimated useful lives, except for certain offshore facilities that apply an accelerated depreciation method.

Gains or losses from the ordinary sale or retirement of property, plant, and equipment for regulated pipelines are 
credited or charged to accumulated depreciation. Other gains or losses are recorded in Other (income) expense – net
included in Operating income (loss) in the Consolidated Statement of Operations.

Ordinary  maintenance  and  repair  costs  are  generally  expensed  as  incurred.  Costs  of  major  renewals  and 

replacements are capitalized as property, plant, and equipment.

We record a liability and increase the basis in the underlying asset for the present value of each expected future 
ARO at the time the liability is initially incurred, typically when the asset is acquired or constructed. As regulated 
entities, Northwest Pipeline and Transco offset the depreciation of the underlying asset that is attributable to capitalized 
ARO cost to a regulatory asset as we expect to recover these amounts in future rates. We measure changes in the liability 
due to passage of time by applying an interest rate to the liability balance. This amount is recognized as an increase in 
the carrying amount of the liability and as a corresponding accretion expense included in Operating and maintenance 
expenses in the Consolidated Statement of Operations, except for regulated entities, for which the liability is offset by 
a regulatory asset. The regulatory asset is amortized commensurate with our collection of those costs in rates.

Measurements of AROs include, as a component of future expected costs, an estimate of the price that a third party 
would demand, and could expect to receive, for bearing the uncertainties inherent in the obligations, sometimes referred 
to as a market-risk premium.

Other intangible assets

Our  identifiable  intangible  assets  included  within  Intangible  assets  –  net  of  accumulated  amortization  in  the 
Consolidated Balance Sheet are primarily related to gas gathering, processing, and fractionation contractual customer 

86

The Williams Companies, Inc.
Notes to Consolidated Financial Statements – (Continued)

relationships. Our intangible assets are amortized on a straight-line basis over the period in which these assets contribute 
to our cash flows. We evaluate these assets for changes in the expected remaining useful lives and would reflect any 
changes prospectively through amortization over the revised remaining useful life.

Impairment of property, plant, and equipment, other identifiable intangible assets, and investments

We evaluate our property, plant, and equipment and other identifiable intangible assets for impairment when events 
or changes in circumstances indicate, in our judgment, that the carrying value of such assets may not be recoverable. 
When an indicator of impairment has occurred, we compare our estimate of undiscounted future cash flows attributable 
to the assets to the carrying value of the assets to determine whether an impairment has occurred and we may apply a 
probability-weighted approach to consider the likelihood of different cash flow assumptions and possible outcomes 
including selling in the near term or holding for the remaining estimated useful life. If an impairment of the carrying 
value has occurred, we determine the amount of the impairment recognized in the financial statements by estimating 
the fair value of the assets and recording a loss for the amount that the carrying value exceeds the estimated fair value. 
This evaluation is performed at the lowest level for which separately identifiable cash flows exist.

For assets identified to be disposed of in the future and considered held for sale, we compare the carrying value 
to the estimated fair value less the cost to sell to determine if recognition of an impairment is required. Until the assets 
are disposed of, the estimated fair value, which includes estimated cash flows from operations until the assumed date 
of sale, is recalculated when related events or circumstances change.

We evaluate our investments for impairment when events or changes in circumstances indicate, in our judgment, 
that the carrying value of such investments may have experienced an other-than-temporary decline in value. When 
evidence of loss in value has occurred, we compare our estimate of fair value of the investment to the carrying value 
of the investment to determine whether an impairment has occurred. If the estimated fair value is less than the carrying 
value and we consider the decline in value to be other-than-temporary, the excess of the carrying value over the fair 
value is recognized in the consolidated financial statements as an impairment charge.

Judgments  and  assumptions  are  inherent  in  our  estimate  of  undiscounted  future  cash  flows  and  an  asset’s  or 
investment’s  fair  value. Additionally,  judgment  is  used  to  determine  the  probability  of  sale  with  respect  to  assets 
considered for disposal.

Contingent liabilities

We record liabilities for estimated loss contingencies, including environmental matters, when we assess that a loss 
is probable, and the amount of the loss can be reasonably estimated. These liabilities are calculated based upon our 
assumptions and estimates with respect to the likelihood or amount of loss and upon advice of legal counsel, engineers, 
or other third parties regarding the probable outcomes of the matters. These calculations are made without consideration 
of any potential recovery from third parties. We recognize insurance recoveries or reimbursements from others when 
realizable. Revisions to these liabilities are generally reflected in income when new or different facts or information 
become known or circumstances change that affect the previous assumptions or estimates.

Cash flows from revolving credit facilities and commercial paper program

Proceeds and payments related to borrowings under our credit facilities are reflected in the financing activities in 
the Consolidated Statement of Cash Flows on a gross basis. Proceeds and payments related to borrowings under our 
commercial paper program are reflected in the financing activities in the Consolidated Statement of Cash Flows on a 
net basis, as the outstanding notes generally have maturity dates less than three months from the date of issuance. (See 
Note 14 – Debt, Banking Arrangements, and Leases.)

Treasury stock

Treasury stock purchases are accounted for under the cost method whereby the entire cost of the acquired stock is 
recorded as Treasury stock in the Consolidated Balance Sheet. Gains and losses on the subsequent reissuance of shares 

87

The Williams Companies, Inc.
Notes to Consolidated Financial Statements – (Continued)

are credited or charged to Capital in excess of par value in the Consolidated Balance Sheet using the average-cost 
method.

Derivative instruments and hedging activities

We may utilize derivatives to manage a portion of our commodity price risk. These instruments consist primarily 
of swaps, futures, and forward contracts involving short-  and long-term purchases and sales of energy commodities. 
We report the fair value of derivatives, except those for which the normal purchases and normal sales exception has 
been elected, in Other current assets and deferred charges; Regulatory assets, deferred charges, and other; Accrued 
liabilities; or Regulatory liabilities, deferred income, and other in the Consolidated Balance Sheet. We determine the 
current and noncurrent classification based on the timing of expected future cash flows of individual trades. We report 
these amounts on a gross basis. Additionally, we report cash collateral receivables and payables with our counterparties 
on a gross basis. (See Note 17 – Fair Value Measurements, Guarantees, and Concentration of Credit Risk.)

The accounting for the changes in fair value of a commodity derivative can be summarized as follows:

Derivative Treatment

Accounting Method

Normal purchases and normal sales exception

  Accrual accounting

Designated in a qualifying hedging relationship

  Hedge accounting

All other derivatives

  Mark-to-market accounting

We may elect the normal purchases and normal sales exception for certain short- and long-term purchases and 
sales of physical energy commodities. Under accrual accounting, any change in the fair value of these derivatives is 
not reflected on the balance sheet after the initial election of the exception.

We may also designate a hedging relationship for certain commodity derivatives. For a derivative to qualify for 
designation in a hedging relationship, it must meet specific criteria and we must maintain appropriate documentation. 
We establish hedging relationships pursuant to our risk management policies. We evaluate the hedging relationships 
at the inception of the hedge and on an ongoing basis to determine whether the hedging relationship is, and is expected 
to remain, highly effective in achieving offsetting changes in fair value or cash flows attributable to the underlying risk 
being hedged. We also regularly assess whether the hedged forecasted transaction is probable of occurring. If a derivative 
ceases to be or is no longer expected to be highly effective, or if we believe the likelihood of occurrence of the hedged 
forecasted transaction is no longer probable, hedge accounting is discontinued prospectively, and future changes in the 
fair value of the derivative are recognized currently in Product sales or Product costs in the Consolidated Statement 
of Operations.

For commodity derivatives designated as a cash flow hedge, the change in fair value of the derivative is reported 
in  AOCI in the Consolidated Balance Sheet and reclassified into earnings in the period in which the hedged item affects 
earnings. Gains or losses deferred in AOCI associated with terminated derivatives, derivatives that cease to be highly 
effective hedges, derivatives for which the forecasted transaction is reasonably possible but no longer probable of 
occurring, and cash flow hedges that have been otherwise discontinued remain in AOCI until the hedged item affects 
earnings. If it becomes probable that the forecasted transaction designated as the hedged item in a cash flow hedge will 
not  occur,  any  gain  or  loss  deferred  in AOCI  is  recognized  in  Product  sales  or  Product  costs  in  the  Consolidated 
Statement of Operations at that time. The change in likelihood of a forecasted transaction is a judgmental decision that 
includes qualitative assessments made by us.

For commodity derivatives that are not designated in a hedging relationship, and for which we have not elected 
the normal purchases and normal sales exception, we report changes in fair value currently in Product sales or Product 
costs in the Consolidated Statement of Operations.

Certain gains and losses on derivative instruments included in the Consolidated Statement of Operations are netted 
together to a single net gain or loss, while other gains and losses are reported on a gross basis. Gains and losses recorded 

88

 
The Williams Companies, Inc.
Notes to Consolidated Financial Statements – (Continued)

on a net basis include unrealized gains and losses on all derivatives that are not designated as hedges and for which we 
have not elected the normal purchases and normal sales exception.

Realized gains and losses on derivatives that require physical delivery, as well as natural gas derivatives for NGL 
processing activities and which are not held for trading purposes nor were entered into as a pre-contemplated buy/sell 
arrangement, are recorded on a gross basis.

Revenue recognition (subsequent to the adoption of ASC 606)

Customers  in  our  gas  pipeline  businesses  are  comprised  of  public  utilities,  municipalities,  gas  marketers  and 
producers, intrastate pipelines, direct industrial users, and electrical generators. Customers in our midstream businesses 
are comprised of oil and natural gas producer counterparties. Customers for our product sales are comprised of public 
utilities, gas marketers, and direct industrial users.

A performance obligation is a promise in a contract to transfer a distinct good or service (or integrated package of 
goods or services) to the customer. A contract’s transaction price is allocated to each distinct performance obligation 
and recognized as revenue, when, or as, the performance obligation is satisfied. A performance obligation is distinct if 
the service is separately identifiable from other items in the integrated package of services and if a customer can benefit 
from it on its own or with other resources that are readily available to the customer. An integrated package of services 
typically represents a single performance obligation if the services are contained within the same contract or within 
multiple contracts entered into in contemplation with one another that are highly interdependent or highly interrelated, 
meaning each of the services is significantly affected by one or more of the other services in the contract. Service 
revenue contracts from our gas pipeline and midstream businesses contain a series of distinct services, with the majority 
of our contracts having a single performance obligation that is satisfied over time as the customer simultaneously 
receives and consumes the benefits provided by our performance. Most of our product sales contracts have a single 
performance obligation with revenue recognized at a point in time when the products have been sold and delivered to 
the customer.

Certain customers reimburse us for costs we incur associated with construction of property, plant, and equipment 
utilized in our operations. For our rate-regulated gas pipeline businesses that apply ASC 980, we follow FERC guidelines 
with respect to reimbursement of construction costs. FERC tariffs only allow for cost reimbursement and are non-
negotiable in nature; thus, the construction activities do not represent an ongoing major and central operation of our 
gas pipeline businesses and are not within the scope of ASC Topic 606, “Revenue from Contracts with Customers” (ASC 
606). Accordingly, cost reimbursements are treated as a reduction to the cost of the constructed asset. For our midstream 
businesses, reimbursement and service contracts with customers are viewed together as providing the same commercial 
objective, as we have the ability to negotiate the mix of consideration between reimbursements and amounts billed 
over time. Accordingly, we generally recognize reimbursements of construction costs from customers on a gross basis 
as a contract liability separate from the associated costs included within property, plant, and equipment. The contract 
liability is recognized into service revenues as the underlying performance obligations are satisfied.

Service Revenues

Gas pipeline businesses: Revenues from our regulated interstate natural gas pipeline businesses, which are subject 
to  regulation  by  certain  state  and  federal  authorities,  including  the  FERC,  include  both  firm  and  interruptible 
transportation and storage contracts. Firm transportation and storage agreements provide for a fixed reservation 
charge based on the pipeline or storage capacity reserved, and a commodity charge based on the volume of natural 
gas delivered/stored, each at rates specified in our FERC tariffs or based on negotiated contractual rates, with 
contract terms that are generally long-term in nature. Most of our long-term contracts contain an evergreen provision, 
which allows the contracts to be extended for periods primarily up to one year in length an indefinite number of 
times following the specified contract term and until terminated generally by either us or the customer. Interruptible 
transportation and storage agreements provide for a volumetric charge based on actual commodity transportation 
or storage utilized in the period in which those services are provided, and the contracts are generally limited to 

89

The Williams Companies, Inc.
Notes to Consolidated Financial Statements – (Continued)

one-month periods or less. Our performance obligations related to our interstate natural gas pipeline businesses 
include the following:

•  Firm  transportation  or  storage  under  firm  transportation  and  storage  contracts—an  integrated  package  of 
services typically constituting a single performance obligation, which includes standing ready to provide such 
services and receiving, transporting or storing (as applicable), and redelivering commodities;

• 

Interruptible transportation and storage under interruptible transportation and storage contracts—an integrated 
package of services typically constituting a single performance obligation once scheduled, which includes 
receiving, transporting or storing (as applicable), and redelivering commodities.

In situations where, in our judgment, we consider the integrated package of services as a single performance 
obligation, which represents a majority of our interstate natural gas pipeline contracts with customers, we do not 
consider there to be multiple performance obligations because the nature of the overall promise in the contract is 
to stand ready (with regard to firm transportation and storage contracts), receive, transport or store, and redeliver 
natural gas to the customer; therefore, revenue is recognized over time upon satisfaction of our daily stand ready 
performance obligation.

We recognize revenues for reservation charges over the performance obligation period, which is the contract 
term, regardless of the volume of natural gas that is transported or stored. Revenues for commodity charges from 
both firm and interruptible transportation services and storage services are recognized when natural gas is delivered 
at the agreed upon delivery point or when natural gas is injected or withdrawn from the storage facility because 
they  specifically  relate  to  our  efforts  to  provide  these  distinct  services.  Generally,  reservation  charges  and 
commodity charges in our interstate natural gas pipeline businesses are recognized as revenue in the same period 
they are invoiced to our customers. As a result of the ratemaking process, certain amounts collected by us may be 
subject to refund upon the issuance of final orders by the FERC in pending rate proceedings. We use judgment to 
record estimates of rate refund liabilities considering our and other third-party regulatory proceedings, advice of 
counsel, and other risks.

Midstream  businesses:  Revenues  from  our  non-regulated  gathering,  processing,  transportation,  and  storage 
midstream businesses include contracts for natural gas gathering, processing, treating, compression, transportation, 
and other related services with contract terms that are generally long-term in nature and may extend up to the 
production life of the associated reservoir. Additionally, our midstream businesses generate revenues from fees 
charged for storing customers’ natural gas and NGLs, generally under prepaid contracted storage capacity contracts. 
In  situations  where,  in  our  judgment,  we  provide  an  integrated  package  of  services  combined  into  a  single 
performance obligation, which represents a majority of this class of contracts with customers, we do not consider 
there to be multiple performance obligations because the nature of the overall promise in the contract is to provide 
gathering, processing, transportation, storage, and related services resulting in the delivery, or redelivery in the 
context of storage services, of pipeline-quality natural gas and NGLs to the customer. As such, revenue is recognized 
at  the  daily  completion  of  the  integrated  package  of  services  as  the  integrated  package  represents  a  single 
performance  obligation. Additionally,  certain  contracts  in  our  midstream  businesses  contain  fixed  or  upfront 
payment terms that result in the deferral of revenues until such services have been performed or such capacity has 
been made available.

We  also  earn  revenues  from  offshore  crude  oil  and  natural  gas  gathering  and  transportation  and  offshore 
production handling. These services represent an integrated package of services and are considered a single distinct 
performance obligation for which we recognize revenues as the services are provided to the customer.

We generally earn a contractually stated fee per unit for the volume of product transported, gathered, processed, 
or stored. The rate is generally fixed; however, certain contracts contain variable rates that are subject to change 
based on commodity prices, levels of throughput, or an annual adjustment based on a formulaic cost of service 
calculation. In addition, we have contracts with contractually stated fees that decline over the contract term, such 
as declines based on the passage of time periods or achievement of cumulative throughput amounts. For all of our 

90

The Williams Companies, Inc.
Notes to Consolidated Financial Statements – (Continued)

contracts, we allocate the transaction price to each performance obligation based on the judgmentally determined 
relative  standalone  selling  price. The  excess  of  consideration  received  over  revenue  recognized  results  in  the 
deferral of those amounts until future periods based on a units of production or straight-line methodology as these 
methods  appropriately  match  the  consumption  of  services  provided  to  the  customer.  The  units  of  production 
methodology requires the use of production estimates that are uncertain and the use of judgment when developing 
estimates of future production volumes, thus impacting the rate of revenue recognition.  Production estimates are 
monitored as circumstances and events warrant. Certain of our gas gathering and processing agreements have 
minimum volume commitments (MVC). If a customer under such an agreement fails to meet its MVC for a specified 
period (thus not exercising all the contractual rights to gathering and processing services within the specified period, 
herein referred to as “breakage”), it is obligated to pay a contractually determined fee based upon the shortfall 
between the actual gathered or processed volumes and the MVC for the period contained in the contract. When 
we conclude, based on management’s judgment, it is probable that the customer will not exercise all or a portion 
of its remaining rights, we recognize revenue associated with such breakage amount in proportion to the pattern 
of exercised rights within the respective MVC period.

Under keep-whole and percent-of-liquids processing contracts, we receive commodity consideration in the 
form of NGLs and take title to the NGLs at the tailgate of the plant. We recognize such commodity consideration 
as service revenue based on the market value of the NGLs retained at the time the processing is provided. The 
current market value, as opposed to the market value at the contract inception date, is used due to a combination 
of factors, including the fact that the volume, mix, and market price of NGL consideration to be received is unknown 
at the time of contract execution and is not specified in our contracts with customers. Additionally, product sales 
revenue (discussed below) is recognized upon the sale of the NGLs to a third party based on the sales price at the 
time of sale. As a result, revenue is recognized both at the time the processing service is provided in Service revenues 
– commodity consideration and at the time the NGLs retained as part of the processing service are sold in Product 
sales. The recognition of revenue related to commodity consideration has the impact of increasing the book value 
of NGL inventory, resulting in higher cost of goods sold at the time of sale. Given that most inventory is sold in 
the same period that it is generated, the impact of these transactions is expected to have little impact to operating 
income.

Product Sales

In the course of providing transportation services to customers of our gas pipeline businesses and gathering 
and processing services to customers of our midstream businesses, we may receive different quantities of natural 
gas  from  customers  than  the  quantities  delivered  on  behalf  of  those  customers. The  resulting  imbalances  are 
primarily settled through the purchase or sale of natural gas with each customer under terms provided for in our 
FERC tariffs or gathering and processing agreements, respectively. Revenue is recognized from the sale of natural 
gas upon settlement of imbalances.

In certain instances, we purchase NGLs, crude oil, and natural gas from our oil and natural gas producer 
customers. In addition, we retain NGLs as consideration in certain processing arrangements, as discussed above 
in the Service Revenues - Midstream businesses section. We recognize revenue from the sale of these commodities 
when the products have been sold and delivered. Our product sales contracts are primarily short-term contracts 
based on prevailing market rates at the time of the transaction.

Contract Assets

Our contract assets primarily consist of revenue recognized under contracts containing MVC features whereby 
management has concluded it is probable there will be a short-fall payment at the end of the current MVC period, 
which typically follows the calendar year, and that a significant reversal of revenue recognized currently for the 
future MVC payment will not occur. As a result, our contract assets related to our future MVC payments are 
generally expected to be collected within the next 12 months and are included within Other current assets and 
deferred charges in our Consolidated Balance Sheet until such time as the MVC short-fall payments are invoiced 
to the customer.

Contract Liabilities

Our  contract  liabilities  consist  of  advance  payments  primarily  from  midstream  business  customers  which 
include construction reimbursements, prepayments, and other billings for which future services are to be provided 
under  the  contract. These  amounts  are  deferred  until  recognized  in  revenue  when  the  associated  performance 
obligation has been satisfied, which is primarily based on a units of production methodology over the remaining 
contractual service periods, and are classified as current or noncurrent according to when such amounts are expected 
to be recognized. Current and noncurrent contract liabilities are included within Accrued liabilities and Regulatory 
liabilities, deferred income, and other, respectively, in our Consolidated Balance Sheet.

Contracts requiring advance payments and the recognition of contract liabilities are evaluated to determine 
whether the advance payments provide us with a significant financing benefit. This determination is based on the 
combined effect of the expected length of time between when we transfer the promised good or service to the 
customer, when the customer pays for those goods or services, and the prevailing interest rates. We have assessed 
our contracts for significant financing components and determined, in our judgment, that one group of contracts 
entered into in contemplation of one another for certain capital reimbursements contains a significant financing 
component. As a result, we recognize noncash interest expense based on the effective interest method and revenue 
(noncash) is recognized when the underlying asset is placed into service utilizing a units of production or straight-
line methodology over the life of the corresponding customer contract.

Revenue recognition (prior to the adoption of ASC 606)

Revenues

As a result of the ratemaking process, certain revenues collected by us may be subject to refunds upon the 
issuance of final orders by the FERC in pending rate proceedings. We record estimates of rate refund liabilities 
considering our and other third-party regulatory proceedings, advice of counsel, and other risks.

Service revenues

Revenues  from  our  interstate  natural  gas  pipeline  businesses  include  services  pursuant  to  long-term  firm 
transportation and storage agreements. These agreements provide for a reservation charge based on the volume of 
contracted capacity and a commodity charge based on the volume of gas delivered, both at rates specified in our 
FERC tariffs. We recognize revenues for reservation charges ratably over the contract period regardless of the 
volume of natural gas that is transported or stored. Revenues for commodity charges, from both firm and interruptible 
transportation services and storage injection and withdrawal services, are recognized when natural gas is delivered 
at the agreed upon delivery point or when natural gas is injected or withdrawn from the storage facility.

Certain revenues from our midstream operations include those derived from natural gas gathering, processing, 
treating, and compression services and are performed under volumetric-based fee contracts. These revenues are 
recorded when services have been performed.

Certain of our gas gathering and processing agreements have minimum volume commitments. If a customer 
under such an agreement fails to meet its minimum volume commitment for a specified period, generally measured 
on an annual basis, it is obligated to pay a contractually determined fee based upon the shortfall between actual 
production volumes and the minimum volume commitment for that period. The revenue associated with minimum 
volume commitments is recognized in the period that the actual shortfall is determined and is no longer subject to 
future reduction or offset, which is generally at the end of the annual period or fourth quarter.

Crude oil gathering and transportation revenues and offshore production handling fees are recognized when 
the services have been performed. Certain offshore production handling contracts contain fixed payment terms 
that result in the deferral of revenues until such services have been performed or such capacity has been made 
available.

92

The Williams Companies, Inc.
Notes to Consolidated Financial Statements – (Continued)

Storage revenues from our midstream operations associated with prepaid contracted storage capacity contracts 

are recognized on a straight-line basis over the life of the contract as services are provided.

Product sales

In the course of providing transportation services to customers of our interstate natural gas pipeline businesses, 
we may receive different quantities of gas from shippers than the quantities delivered on behalf of those shippers. 
The resulting imbalances are primarily settled through the purchase and sale of gas with our customers under terms 
provided for in our FERC tariffs. Revenue is recognized from the sale of gas upon settlement of the transportation 
and exchange imbalances.

We market NGLs, crude oil, and natural gas that we purchase from our producer customers as part of the 
overall service provided to producers. Revenues from marketing activities are recognized when the products have 
been sold and delivered.

Under our keep-whole and percent-of-liquids processing contracts, we retain the rights to all or a portion of 
the NGLs extracted from the producers’ natural gas stream and recognize revenues when the extracted NGLs are 
sold and delivered.

Our  former  domestic  olefins  business  produced  olefins  from  purchased  or  produced  feedstock  and  we 

recognized revenues when the olefins were sold and delivered.

Our Canadian businesses that were sold in September 2016 had processing and fractionation operations where 
we retained certain NGLs and olefins from an upgrader’s offgas stream and we recognized revenues when the 
fractionated products were sold and delivered.

Interest capitalized

We capitalize interest during construction on major projects with construction periods of at least 3 months and a 
total project cost in excess of $1 million. Interest is capitalized on borrowed funds and, where regulation by the FERC 
exists, on internally generated funds (equity AFUDC). The latter is included in Other income (expense) – net below 
Operating  income  (loss)  in  the  Consolidated  Statement  of  Operations. The  rates  used  by  regulated  companies  are 
calculated in accordance with FERC rules. Rates used by nonregulated companies are based on our average interest 
rate on debt.

Employee stock-based awards

We  recognize  compensation  expense  on  employee  stock-based  awards  on  a  straight-line  basis;  forfeitures  are 

recognized when they occur. (See Note 16 – Equity-Based Compensation.)

Pension and other postretirement benefits

The funded status of each of the pension and other postretirement benefit plans is recognized separately in the 
Consolidated Balance Sheet as either an asset or liability. The funded status is the difference between the fair value of 
plan assets and the plan’s benefit obligation. The plans’ benefit obligations and net periodic benefit costs (credits) are 
actuarially determined and impacted by various assumptions and estimates. (See Note 10 – Employee Benefit Plans.)

The discount rates are determined separately for each of our pension and other postretirement benefit plans based 
on an approach specific to our plans. The year-end discount rates are determined considering a yield curve comprised 
of high-quality corporate bonds and the timing of the expected benefit cash flows of each plan.

The expected long-term rates of return on plan assets are determined by combining a review of the historical returns 
within the portfolio, the investment strategy included in the plans’ investment policy statement, and capital market 
projections for the asset classes in which the portfolio is invested, as well as the weighting of each asset class.

93

The Williams Companies, Inc.
Notes to Consolidated Financial Statements – (Continued)

Unrecognized actuarial gains and losses and unrecognized prior service costs and credits are deferred and recorded 
in AOCI or, for Transco and Northwest Pipeline, as a regulatory asset or liability, until amortized as a component of 
net periodic benefit cost (credit). Unrecognized actuarial gains and losses in excess of 10 percent of the greater of the 
benefit obligation or the market-related value of plan assets are amortized over the participants’ average remaining 
future years of service, which is approximately 13 years for our pension plans and approximately 7 years for our other 
postretirement benefit plans.

The expected return on plan assets component of net periodic benefit cost (credit) is calculated using the market-
related value of plan assets. For our pension plans, the market-related value of plan assets is equal to the fair value of 
plan assets adjusted to reflect the amortization of gains or losses associated with the difference between the expected 
and actual return on plan assets over a 5-year period. Additionally, the market-related value of assets may be no more 
than 110 percent or less than 90 percent of the fair value of plan assets at the beginning of the year. The market-related 
value of plan assets for our other postretirement benefit plans is equal to the unadjusted fair value of plan assets at the 
beginning of the year.

Income taxes

We include the operations of our domestic corporate subsidiaries and income from our subsidiary partnerships in 
our consolidated federal income tax return and also file tax returns in various foreign and state jurisdictions as required. 
Deferred income taxes are computed using the liability method and are provided on all temporary differences between 
the financial basis and the tax basis of our assets and liabilities. Our judgment and income tax assumptions are used to 
determine the levels, if any, of valuation allowances associated with deferred tax assets.

Earnings (loss) per common share

Basic earnings (loss) per common share in the Consolidated Statement of Operations is based on the sum of the 
weighted-average number of common shares outstanding and vested restricted stock units. Diluted earnings (loss) per 
common share in the Consolidated Statement of Operations includes any dilutive effect of stock options, nonvested 
restricted stock units, and convertible debt, unless otherwise noted. Diluted earnings (loss) per common share are 
calculated using the treasury-stock method.

Accounting standards issued and adopted

During  the  first  quarter  of  2018,  we  early  adopted Accounting  Standards  Update  (ASU)  2018-02  “Income 
Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated 
Other Comprehensive Income” (ASU 2018-02). As a result of Tax Reform lowering the federal income tax rate and 
prior to adopting this standard, the tax effects of items within accumulated other comprehensive income may not have 
reflected the appropriate tax rate. ASU 2018-02 allows for the reclassification from accumulated other comprehensive 
income to retained earnings for stranded tax effects resulting from Tax Reform. The adoption of ASU 2018-02 resulted 
in the reclassification of $61 million from Accumulated other comprehensive income (loss) to Retained deficit on our 
Consolidated Balance Sheet.

Effective  January  1,  2018,  we  adopted  ASU  2017-12  “Derivatives  and  Hedging  (Topic  815):  Targeted 
Improvements to Accounting for Hedging Activities” (ASU 2017-12). ASU 2017-12 applies to entities that elect hedge 
accounting in accordance with ASC 815. The ASU affects both the designation and measurement guidance for hedging 
relationships and the presentation of hedging results.  ASU 2017-12 was applied using a modified retrospective approach 
for cash flow and net investment hedges existing at the date of adoption and prospectively for the presentation and 
disclosure guidance. The adoption of ASU 2017-12 did not have a significant impact on our consolidated financial 
statements.

In May 2014, the Financial Accounting Standards Board (FASB) issued ASU 2014-09 establishing ASC 606. ASC 
606 establishes a comprehensive new revenue recognition model designed to depict the transfer of goods or services 
to a customer in an amount that reflects the consideration the entity expects to be entitled to receive in exchange for 
those goods or services and requires significantly enhanced revenue disclosures. In August 2015, the FASB issued ASU 

94

The Williams Companies, Inc.
Notes to Consolidated Financial Statements – (Continued)

2015-14 “Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date” (ASU 2015-14). Per 
ASU 2015-14, the standard became effective for interim and annual reporting periods beginning after December 15, 
2017.

We adopted the provisions of ASC 606 effective January 1, 2018, utilizing the modified retrospective transition 
method for all contracts with customers, which included applying the provisions of ASC 606 beginning January 1, 
2018, to all contracts not completed as of that date with the cumulative effect of applying the standard for periods prior 
to January 1, 2018, as an adjustment to Total equity, net of tax, upon adoption. As a result of our adoption, the cumulative 
impact to our Total equity, net of tax, at January 1, 2018, was a decrease of $121 million in the Consolidated Balance 
Sheet.

For each revenue contract type, we conducted a formal contract review process to evaluate the impact of ASC 606. 
The adjustment to Total equity upon adoption of ASC 606 is primarily comprised of the impact to the timing of recognition 
of deferred revenue (contract liabilities) associated with certain contracts which underwent modifications in periods 
prior to January 1, 2018. Under the provisions of ASC 606, when a contract modification does not increase both the 
scope and price of the contract, and the remaining goods and services are distinct from the goods and services transferred 
prior to the modification, the modification is treated as a termination of the existing contract and the creation of a new 
contract. ASC 606 requires that the transaction price, including any remaining contract liabilities from the old contract, 
be allocated to the performance obligations over the term of the new contract. The contract modification adjustments 
are partially offset by the impact of changes to the timing of recognizing revenue which is subject to the constraint on 
estimates  of  variable  consideration  of  certain  contracts. The  constraint  of  variable  consideration  will  result  in  the 
acceleration of revenue recognition and corresponding de-recognition of contract liabilities for certain contracts (as 
compared to the previous revenue recognition model) as a result of our assessment that it is probable such recognition 
would not result in a significant revenue reversal in the future. Additionally, under ASC 606, our revenues will increase 
in situations where we receive noncash consideration, which exists primarily in certain of our gas processing contracts 
where we receive commodities as full or partial consideration for services provided. This increase in revenues will be 
offset by a similar increase in costs and expenses when the commodities received are subsequently sold. Financial 
systems and internal controls necessary for adoption were implemented effective January 1, 2018. (See Note 2 – Revenue 
Recognition.)

Accounting standards issued but not yet adopted

In June 2016, the FASB issued ASU 2016-13 “Financial Instruments - Credit Losses (Topic 326): Measurement 
of Credit Losses on Financial Instruments” (ASU 2016-13). ASU 2016-13 changes the impairment model for most 
financial assets and certain other instruments. For trade and other receivables, held-to-maturity debt securities, loans, 
and other instruments, entities will be required to use a new forward-looking “expected loss” model that generally will 
result in the earlier recognition of allowances for losses. The guidance also requires increased disclosures. ASU 2016-13 
is effective for interim and annual periods beginning after December 15, 2019. Early adoption is permitted. The standard 
requires varying transition methods for the different categories of amendments. Although we do not expect ASU 2016-13 
to have a significant impact, it could impact our trade receivables as the related allowance for credit losses will be 
recognized earlier under the expected loss model.

In February 2016, the FASB issued ASU 2016-02 “Leases (Topic 842)” (ASU 2016-02). ASU 2016-02 establishes 
a comprehensive new lease accounting model. ASU 2016-02 modifies the definition of a lease, requires a dual approach 
to lease classification similar to current lease accounting, and causes lessees to recognize operating leases on the balance 
sheet as a lease liability measured as the present value of the future lease payments with a corresponding right-of-use 
asset, with an exception for leases with a term of one year or less. Additional disclosures will also be required regarding 
the amount, timing, and uncertainty of cash flows arising from leases. In January 2018, the FASB issued ASU 2018-01 
“Leases (Topic 842): Land Easement Practical Expedient for Transition to Topic 842” (ASU 2018-01). Per ASU 2018-01, 
land easements and rights-of-way are required to be assessed under ASU 2016-02 to determine whether the arrangements 
are or contain a lease. ASU 2018-01 permits an entity to elect a transition practical expedient to not apply ASU 2016-02 
to land easements that exist or expired before the effective date of ASU 2016-02 and that were not previously assessed 
under the previous lease guidance in ASC Topic 840 “Leases.”

95

The Williams Companies, Inc.
Notes to Consolidated Financial Statements – (Continued)

In July 2018, the FASB issued ASU 2018-11 “Leases (Topic 842): Targeted Improvements” (ASU 2018-11). Prior 
to ASU 2018-11, a modified retrospective transition was required for financing or operating leases existing at or entered 
into after the beginning of the earliest comparative period presented in the financial statements. ASU 2018-11 allows 
entities an additional transition method to the existing requirements whereby an entity could adopt the provisions of 
ASU 2016-02 by recognizing a cumulative-effect adjustment to the opening balance of retained earnings in the period 
of adoption without adjustment to the financial statements for periods prior to adoption. ASU 2018-11 also allows a 
practical expedient that permits lessors to not separate non-lease components from the associated lease component if 
certain conditions are present. ASU 2016-02 is effective for interim and annual periods beginning after December 15, 
2018. Early adoption is permitted. We are adopting ASU 2016-02 effective January 1, 2019.

We are substantially complete with our review of contracts to identify leases based on the modified definition of 
a lease and implementing changes to our internal controls to support management in the accounting for and disclosure 
of leasing activities upon adoption of ASU 2016-02. We implemented a financial lease accounting system to assist 
management in the accounting for leases upon adoption. We are substantially complete with the implementation of 
ASU 2016-02 and believe the most significant changes to our financial statements relate to the recognition of a lease 
liability and offsetting right-of-use asset in our Consolidated Balance Sheet for operating leases, which we estimate to 
be less than 1 percent of total liabilities and total assets, respectively. We have also evaluated ASU 2016-02’s available 
practical expedients on adoption. We generally elected to adopt the practical expedients, which includes the practical 
expedient to not separate lease and non-lease components by both lessees and lessors by class of underlying assets and 
the land easements practical expedient.

Remaining Performance Obligations

The following table presents the transaction price allocated to the remaining performance obligations under certain

midstream  businesses,  fixed  payments  associated  with  offshore  production  handling,  and  reservation  charges  on 
contracted  capacity  on  our  gas  pipeline  firm  transportation  contracts  with  customers,  as  well  as  storage  capacity 
contracts. Amounts included in the table below for our interstate natural gas pipeline businesses reflect the rates for 
such services in our current FERC tariffs for the life of the related contracts; however, these rates may change based 
on future tariffs approved by the FERC and the amount and timing of these changes is not currently known. As a 
practical expedient permitted by ASC 606, this table excludes variable consideration as well as consideration in contracts 
that is recognized in revenue as billed.  It also excludes consideration received prior to December 31, 2018, that will 
be recognized in future periods (see above for Contract Liabilities and the expected recognition of those amounts within 
revenue).  Certain of our contracts contain evergreen and other renewal provisions for periods beyond the initial term 
of the contract. The remaining performance obligation amounts as of December 31, 2018, do not consider potential 
future performance obligations for which the renewal has not been exercised.

Impact of Adoption of ASC 606

The following table depicts the impact of the adoption of ASC 606 on our 2018 financial statements.  The adjustment 
to Intangible assets – net of accumulated amortization in the table below relates to the recognition under ASC 606 of 
contract assets for MVC-related contracts associated with a 2014 acquisition. The recognition of these contract assets 
resulted in a lower purchase price allocation to intangible assets.  The adoption of ASC 606 did not result in adjustments 
to total operating, investing, or financing cash flows.

Note 3 – Divestitures 

Sale of Gulf Coast Pipeline Systems

In November 2018, we completed the sale of certain assets and operations located in the Gulf Coast area for $177 
million in cash. These assets were designated as held for sale during the third quarter of 2018. As a result of this sale, 
we recorded a gain of approximately $101 million in the fourth quarter of 2018, consisting of $81 million in our Atlantic-
Gulf segment and $20 million in Other.

Previous impairments made to a portion of these assets and operations include $66 million related to certain idle 
pipelines in the second quarter of 2018, as well as $68 million and $23 million related to an NGL pipeline near the 
Houston Ship Channel region and project development costs associated with an olefins pipeline project, respectively, 
in 2017. These impairments are reflected in Impairment of certain assets in the Consolidated Statement of Operations. 
(See Note 17 – Fair Value Measurements, Guarantees, and Concentration of Credit Risk.) The results of operations for 
this disposal group, excluding the impairments and gains noted, were not significant for the reporting periods.

Sale of Four Corners Assets

In October 2018, we completed the sale of our natural gas gathering and processing assets in the Four Corners 
area  of  New  Mexico  and  Colorado  for  total  consideration  of  $1.125  billion,  subject  to  customary  working  capital 
adjustments. These assets were designated as held for sale during the third quarter of 2018. As a result of this sale, we 
recorded a gain of approximately $591 million within the West segment in the fourth quarter of 2018. 

The following table presents the results of operations for the Four Corners area, excluding the gain noted above:

Sale of Geismar Interest

In July 2017, we completed the sale of Williams Olefins, L.L.C., a wholly owned subsidiary which owned our 
Geismar Interest for total consideration of $2.084 billion in cash. We received a final working capital adjustment of 
$12 million in October 2017. Upon closing of the sale, we entered into a long-term supply and transportation agreement 
with the purchaser to provide feedstock to the plant via its Bayou Ethane pipeline system. As a result of this sale, we 
recorded a gain of $1.095 billion in the third quarter of 2017 in our Other segment. Following this sale, the cash proceeds 
were used to repay our $850 million term loan.

Sale of Canadian Operations

In September 2016, we completed the sale of subsidiaries conducting Canadian operations (such subsidiaries, the 
Canadian disposal group). Consideration received totaled $1.020 billion, net of $31 million of cash divested and subject 
to customary working capital adjustments.

During 2016, we designated these operations as held for sale. As a result, we measured the fair value of the disposal 
group, resulting in an impairment charge of $747 million, reflected in Impairment of certain assets in the Consolidated 
Statement of Operations. (See Note 17 – Fair Value Measurements, Guarantees, and Concentration of Credit Risk.) 
Upon completion of the sale, we also recorded a loss of $66 million in Other, primarily reflecting revisions to the sales 
price and estimated contingent consideration. This included a $15 million benefit related to transactions to hedge our 
foreign currency exchange risk on the Canadian proceeds, reflected in Other (income) expense – net within Costs and 
expenses in the Consolidated Statement of Operations. 

For the year ended December 31, 2016, the results of operations for the Canadian disposal group, excluding the 
impairment and loss noted, were a loss before income taxes of $98 million, and a loss before income taxes attributable 
to The Williams Companies, Inc. of $95 million, in Other. 

Note 4 – Variable Interest Entities

Consolidated VIEs

As of December 31, 2018, we consolidate the following VIEs:

Gulfstar One

We own a 51 percent interest in Gulfstar One, a subsidiary that, due to certain risk-sharing provisions in its customer 
contracts,  is  a VIE.  Gulfstar  One  includes  a  proprietary  floating-production  system,  Gulfstar  FPS,  and  associated 
pipelines which provide production handling and gathering services in the eastern deepwater Gulf of Mexico. We are 
the primary beneficiary because we have the power to direct the activities that most significantly impact Gulfstar One’s 
economic performance.

Constitution

We own a 41 percent interest in Constitution, a subsidiary that, due to shipper fixed-payment commitments under 
its long-term firm transportation contracts, is a VIE. We are the primary beneficiary because we have the power to 
direct the activities that most significantly impact Constitution’s economic performance. We, as operator of Constitution, 
are  responsible  for  constructing  the  proposed  pipeline  connecting  its  gathering  system  in  Susquehanna  County, 
Pennsylvania, to the Iroquois Gas Transmission and the Tennessee Gas Pipeline systems. The total remaining cost of 
the project is estimated to be approximately $740 million, which would be funded with capital contributions from us 
and the other equity partners on a proportional basis.

In December 2014, Constitution received approval from the FERC to construct and operate its proposed pipeline. 
However,  in April  2016,  the  New York  State  Department  of  Environmental  Conservation  (NYSDEC)  denied  the 
necessary water quality certification under Section 401 of the Clean Water Act for the New York portion of the pipeline. 
In May 2016, Constitution appealed the NYSDEC’s denial of the Section 401 certification to the United States Court 
of Appeals for the Second Circuit and in August 2017, the court issued a decision denying in part and dismissing in 
part  Constitution’s  appeal.  The  court  expressly  declined  to  rule  on  Constitution’s  argument  that  the  delay  in  the 
NYSDEC’s decision on Constitution’s Section 401 application constitutes a waiver of the certification requirement. 
The court determined that it lacked jurisdiction to address that contention and found that jurisdiction over the waiver 
issue lies exclusively with the United States Court of Appeals for the District of Columbia Circuit (D.C. Circuit). As 
to the denial itself, the court determined that NYSDEC’s action was not arbitrary or capricious. Constitution filed a 
petition for rehearing with the Second Circuit Court of Appeals, but in October 2017 the court denied our petition.

102

The Williams Companies, Inc.
Notes to Consolidated Financial Statements – (Continued)

In October 2017, we filed a petition for declaratory order requesting the FERC to find that, by operation of law, 
the Section 401 certification requirement for the New York State portion of Constitution’s pipeline project was waived 
due to the failure by the NYSDEC to act on Constitution’s Section 401 application within a reasonable period of time 
as required by the express terms of such statute. In January 2018, the FERC denied our petition, finding that Section 
401 provides that a state waives certification only when it does not act on an application within one year from the date 
of the application. We filed a request for rehearing of the FERC’s decision, but in July 2018 the FERC denied our 
request.

The project’s sponsors remain committed to the project. On November 5, 2018, the FERC granted our request for 
an extension of time to December 2, 2020, to construct and place into service the Constitution pipeline. And, in September 
2018, we filed a petition with the D.C. Circuit for review of the FERC’s denial of our petition for declaratory order. 
An unfavorable resolution of that appeal could result in the impairment of a significant portion of the capitalized project 
costs, which total $377 million on a consolidated basis at December 31, 2018, and are included within Property, plant, 
and equipment – net in the Consolidated Balance Sheet. Beginning in April 2016, we discontinued capitalization of 
development costs related to this project. It is also possible that we could incur certain supplier-related costs in the 
event of a continued prolonged delay or termination of the project.  

Cardinal

We own a 66 percent interest in Cardinal, a subsidiary that provides gathering services for the Utica Shale region 
and is a VIE due to certain risks shared with customers. We are the primary beneficiary because we have the power to 
direct  the  activities  that  most  significantly  impact  Cardinal’s  economic  performance.  Future  expansion  activity  is 
expected to be funded with capital contributions from us and the other equity partner on a proportional basis.

Nonconsolidated VIEs

Jackalope

We own a 50 percent interest in Jackalope, which provides gathering and processing services for the Powder River 
basin and is a VIE due to certain risks shared with customers. Prior to the second quarter of 2018 we were the primary 
beneficiary of Jackalope. During the second quarter of 2018, the scope of Jackalope’s planned future activities changed, 
resulting in a VIE reconsideration event. Upon evaluation, we determined that we are no longer the primary beneficiary, 
most notably due to changes in the activities that most significantly impact Jackalope’s economic performance and our 
determination that we do not control the power to direct such activities. These activities are primarily related to the 
capital decision making process.  As a result, we deconsolidated Jackalope on June 30, 2018 and now account for our 
interest using the equity method of accounting as we exert significant influence over the financial and operational 
policies of Jackalope (see Note 6 – Investing Activities). At December 31, 2018, the carrying value of our investment 
in Jackalope was $343 million. Our maximum exposure to loss is limited to the carrying value of our investment. 
Jackalope is currently undertaking an expansion project with a remaining cost up to approximately $350 million as of 
December 31, 2018, which will be funded on a proportional basis.

Notes to Consolidated Financial Statements – (Continued)

Brazos Permian II

We own a 15 percent interest in Brazos Permian II (see Note 6 – Investing Activities), which provides gathering 
and processing services in the Delaware basin and is a VIE due primarily to our limited participating rights as the 
minority equity holder.  At December 31, 2018, the carrying value of our investment in Brazos Permian II was $191 
million. Our maximum exposure to loss is limited to the carrying value of our investment.

Note 5 – Related Party Transactions

Transactions with Equity-Method Investees

We have purchases from our equity-method investees included in Product costs in the Consolidated Statement of 
Operations of $236 million, $226 million, and $180 million for the years ended 2018, 2017, and 2016, respectively. 
We have $18 million and $20 million included in Accounts payable in the Consolidated Balance Sheet with our equity-
method investees at December 31, 2018 and 2017, respectively.

We have operating agreements with certain equity-method investees. These operating agreements typically provide 
for reimbursement or payment to us for certain direct operational payroll and employee benefit costs, materials, supplies, 
and other charges and also for management services. The total charges to equity-method investees for these fees are 
$75 million, $67 million, and $66 million for the years ended 2018, 2017, and 2016, respectively.

Board of Directors

A former member of our Board of Directors, who was elected in 2013 and resigned during 2016, is also the current 
chairman, president, and chief executive officer of an energy services company that is a customer of ours. We recorded  
$144 million in Service revenues in the Consolidated Statement of Operations from this company for transportation 
and storage of natural gas for the year ended December 31, 2016. 

Note 6 – Investing Activities

Brazos Permian II Equity-Method Investment

During the fourth quarter of 2018, we contributed the majority of our existing Delaware basin assets and $27 
million in cash in exchange for a 15 percent interest in the Brazos Permian II, which consists of  gas and crude oil 
gathering pipelines, natural gas processing, and oil storage facilities. We recorded a deconsolidation gain of $141 million
reflected in Other investing income (loss) – net in the Consolidated Statement of Operations reflecting the excess of the 
fair value of our acquired interest over the carrying value of the assets contributed. We estimated the fair value of our 
interest to be $192 million primarily using a market approach (a Level 3 measurement within the fair value hierarchy). 
This approach involved the observation of recent transaction multiples in the Permian basin, including recent acquisitions 
consummated during 2018. Our interest in Brazos Permian II is considered an equity-method investment due to the 
fact that we are able to exert significant influence over its operating and financial policies.

RMM Equity-Method Investment

During the third quarter of 2018, our joint venture, RMM, purchased a natural gas and oil gathering and natural 
gas processing business in Colorado’s Denver-Julesburg basin. Our initial economic ownership was 40 percent, which 
has since increased to 50 percent at December 31, 2018, based on additional capital contributions made since the initial 
purchase.

Jackalope Deconsolidation

During the second quarter of 2018, we deconsolidated our interest in Jackalope (see Note 4 – Variable Interest 
Entities). We recorded our interest in Jackalope as an equity-method investment at its estimated fair value, resulting in 
a deconsolidation gain of $62 million reflected in Other investing income (loss) – net in the Consolidated Statement of 
Operations. We estimated the fair value of our interest to be $310 million using an income approach based on expected 

105

The Williams Companies, Inc.
Notes to Consolidated Financial Statements – (Continued)

future  cash  flows  and  an  appropriate  discount  rate  (a  Level  3  measurement  within  the  fair  value  hierarchy).  The 
determination  of  expected  future  cash  flows  involved  significant  assumptions  regarding  gathering  and  processing 
volumes and related capital spending. A 10.9 percent discount rate was utilized and reflected our estimate of the cost 
of capital as impacted by market conditions and risks associated with the underlying business. The deconsolidated 
carrying value of the net assets of Jackalope included $47 million of goodwill.

Acquisition of Additional Interests in Appalachia Midstream Investments

During the first quarter of 2017, we exchanged all of our 50 percent interest in DBJV for an increased interest in 
two natural gas gathering systems that are part of the Appalachia Midstream Investments and $155 million in cash. 
This transaction was recorded based on our estimate of the fair value of the interests received as we have more insight 
to this value as we operate the underlying assets. Following this exchange, we have an approximate average 66 percent 
interest in the Appalachia Midstream Investments. We continue to account for this investment under the equity method 
of accounting due to the significant participatory rights of our partners such that we do not exercise control. We also 
sold all of our interest in Ranch Westex JV LLC (Ranch Westex) for $45 million. These transactions resulted in a total 
gain of $269 million reflected in Other investing income (loss) – net in the Consolidated Statement of Operations. 

The fair value of the increased interests in the Appalachia Midstream Investments received as consideration was 
estimated to be $1.1 billion using an income approach based on expected cash flows and an appropriate discount rate 
(a Level 3 measurement within the fair value hierarchy). The determination of estimated future cash flows involved 
significant assumptions regarding gathering volumes, rates, and related capital spending. A 9.5 percent discount rate 
was utilized and reflected our estimate of the cost of capital as impacted by market conditions and risks associated with 
the underlying business.

Other investing income (loss) – net

In 2016, we recognized a $27 million gain from the sale of an equity-method investment interest in a gathering 

system that was part of the Appalachia Midstream Investments.

Other investing income (loss) – net also includes $36 million of interest income for 2016 associated with a receivable 
related to the sale of certain former Venezuela assets. Due to changes in circumstances that led to late payments and 
increased uncertainty regarding the recovery of the receivable, we began accounting for the receivable under a cost 
recovery model in first quarter 2015. Subsequently, we received payments greater than the remaining carrying amount 
of the receivable, which resulted in the recognition of interest income.

Income (loss) before income taxes includes $3 million, $7 million, and $885 million of foreign loss in 2018, 2017, 

and 2016, respectively.

Foreign operations – net (including tax effect of Canadian Sale) in 2016 reflects a valuation allowance associated 
with impairments and losses on the sale of our Canadian operations (see Note 3 – Divestitures) and the reversal of 
anticipatory  foreign  tax  credits,  partially  offset  by  the  tax  effect  of  the  impairments  associated  with  our  Canadian 
disposition. 2017 reflects the release of this valuation allowance.

On December 22, 2017, Tax Reform was enacted. Most of the provisions of Tax Reform were effective after 
January 1, 2018.  However, the deferred tax impact of reducing the U.S. corporate tax rate from 35 percent to 21 percent
was recognized in the period of enactment.  This remeasurement resulted in a reduction of our deferred tax liabilities 
of approximately $1.9 billion, with a corresponding net adjustment to Provision (benefit) for income taxes in 2017.

During the course of audits of our business by domestic and foreign tax authorities, we frequently face challenges 
regarding the amount of taxes due. These challenges include questions regarding the timing and amount of deductions 
and the allocation of income among various tax jurisdictions. In evaluating the liability associated with our various 

111

 
 
 
The Williams Companies, Inc.
Notes to Consolidated Financial Statements – (Continued)

filing positions, we apply the two-step process of recognition and measurement. In association with this liability, we 
record an estimate of related interest and tax exposure as a component of our tax provision. The impact of this accrual 
is included within Other – net in our reconciliation of the Provision (benefit) at statutory rate to recorded Provision 
(benefit) for income taxes.

Significant components of Deferred income tax liabilities and Deferred income tax assets are as follows. Following 

the WPZ Merger, the attributes below are presented based on the underlying assets.

The valuation allowance at December 31, 2018 and 2017 serves to reduce the available deferred income tax assets 
to an amount that will, more likely than not, be realized. We consider all available positive and negative evidence, 
including projected future taxable income, which incorporates available tax planning strategies, and management’s 
estimate of future reversals of existing taxable temporary differences, and have determined that a portion of our deferred 
income tax assets related to the Foreign tax credit and State losses and credits may not be realized. The Valuation 
allowance change from 2017 is primarily due to a $105 million valuation allowance associated with foreign tax credits, 
that expire between 2024 and 2028. The completion of the WPZ Merger (see Note 1 – General, Description of Business, 
Basis  of  Presentation,  and  Summary  of  Significant Accounting  Policies)  was  a  taxable  exchange  to  the WPZ  unit 
holders, which resulted in an adjustment to the tax basis in the underlying assets deemed acquired. A reduction to the 
deferred tax liability of  $1.829 billion related to the book-tax basis difference in this investment has been recorded.  
Increased tax depreciation from the additional tax basis will reduce future taxable income, which serves to impact our 
expected realization of the Foreign tax credit. The amounts presented in the table above are, with respect to state items, 
before any federal benefit. The change from prior year for the State losses and credits reflects increases in losses and 
credits generated in the current and prior years less losses and/or credits utilized in the current year. We have loss and 
credit carryovers in multiple state taxing jurisdictions. Additionally, valuation allowances on state net operating losses 
decreased by $31 million after the completion of the WPZ Merger. These attributes generally expire between 2019 and 
2038 with some carryovers having indefinite carryforward periods. The remaining federal Minimum tax credit of $71 
million will be refunded/utilized no later than 2021. 

Federal loss carryovers includes deferred tax assets of $5 million at the end of 2018 that are expected to be utilized 
by us prior to expiration between 2019 and 2023. Deferred tax assets on net operating loss carryovers of $142 million
have no expiration date.

Cash payments for income taxes (net of refunds) were $11 million, $28 million, and $5 million in 2018, 2017, and 

2016, respectively. 

As of December 31, 2018, we had approximately $51 million of unrecognized tax benefits. If recognized, income 
tax expense would be reduced by $51 million and $50 million for 2018 and 2017, respectively, including the effect of 
these changes on other tax attributes, with state income tax amounts included net of federal tax effect. A reconciliation 
of the beginning and ending amount of unrecognized tax benefits is as follows:

We recognize related interest and penalties as a component of Provision (benefit) for income taxes. Total interest 
and penalties recognized as part of income tax provision were expenses of $800 thousand and $300 thousand for 2018 
and 2016, respectively, and a benefit of $400 thousand for 2017. Approximately $3 million and $2 million of interest 
and  penalties  primarily  relating  to  uncertain  tax  positions  have  been  accrued  as  of  December 31,  2018  and  2017, 
respectively. 

During the next 12 months, we do not expect ultimate resolution of any unrecognized tax benefit associated with 

domestic or international matters to have a material impact on our unrecognized tax benefit position.

Consolidated U.S. Federal income tax returns are open to Internal Revenue Service (IRS) examination for years 
after 2010. As of December 31, 2018, examinations of tax returns for 2011 through 2013 are currently in process. We 
do not expect material changes in our financial position resulting from these examinations. The statute of limitations 
for most states expires one year after expiration of the IRS statute. Generally, tax returns for our previously owned 
Canadian entities are open to audit for tax years after 2013. Tax years 2013 through 2016 are currently under examination. 
We have indemnified the purchaser for any adjustments to Canadian tax returns for periods prior to the sale of our 
Canadian operations in September 2016.

Note 10 – Employee Benefit Plans

We have noncontributory defined benefit pension plans in which all eligible employees participate. Currently, 
eligible employees earn benefits primarily based on a cash balance formula. At the time of retirement, participants may 
elect, to the extent they are eligible for the various options, to receive annuity payments, a lump-sum payment, or a 
combination of annuity and lump-sum payments. In addition to our pension plans, we currently provide subsidized 
retiree medical and life insurance benefits (other postretirement benefits) to certain eligible participants. Generally, 
employees  hired  after  December 31,  1991,  are  not  eligible  for  the  subsidized  retiree  medical  benefits,  except  for 
participants that were employees or retirees of Transco Energy Company on December 31, 1995. Subsidized retiree 
medical benefits for eligible participants age 65 and older are paid through contributions to health reimbursement 
accounts. Subsidized retiree medical benefits for eligible participants under age 65 are provided through a self-insured 
medical plan sponsored by us. The self-insured retiree medical plan provides for retiree contributions and contains 
other cost-sharing features such as deductibles, co-payments, and co-insurance. The accounting for this plan anticipates 
estimated future increases to our contribution levels to the health reimbursement accounts for participants age 65 and 
older, as well as future cost-sharing that is consistent with our expressed intent to increase the retiree contribution level 
generally in line with health care cost increases for participants under age 65. 

In November 2018, we announced changes to our defined benefit pension plans and our defined contribution plan. 
Eligible employees hired or rehired on or after January 1, 2019, will not be eligible to participate in the pension plan, 
but will be eligible for an additional fixed annual contribution made by us to the defined contribution plan. Additionally, 
as of January 1, 2020, certain active eligible employees will no longer receive future compensation credits under the 
defined benefit pension plan, but will be eligible for an additional fixed annual contribution made by us to the defined 
contribution plan. Also as of January 1, 2020, certain active eligible employees will continue to receive compensation 
credits under the defined benefit pension plans and these employees will not be eligible to receive the fixed annual 
contribution under the defined contribution plan. As a result of this amendment, a curtailment gain and a prior service 
credit were recorded to Accumulated other comprehensive income (loss). The amounts of the curtailment gain and prior 
service credit were not significant and are reported in Net actuarial gain (loss) within the subsequent tables of changes 
in benefit obligations, amounts included in Accumulated other comprehensive income (loss), and other changes in plan 
assets and benefit obligations recognized in other comprehensive income (loss) before taxes.  

In September 2017, we initiated a program to pay out certain deferred vested pension benefits to reduce investment 
risk, cash funding volatility, and administrative costs. In December 2017 and August 2018, lump-sum payments were 
made, and annuity payments commenced in relation to this program. As a result of these lump-sum payments, as well 
as lump-sum benefit payments made throughout 2017 and 2018, settlement accounting was required. We settled $103 
million in liabilities of our pension plans in 2018 and $261 million in 2017 and recognized pre-tax, noncash settlement 
charges of $23 million in 2018 and $71 million in 2017, which are substantially reported in Other income (expense) –
 net below Operating income (loss) in the Consolidated Statement of Operations (see Note 7 – Other Income and 
Expenses). These amounts are included within the subsequent tables of changes in benefit obligations and plan assets, 
net  periodic  benefit  cost  (credit),  and  other  changes  in  plan  assets  and  benefit  obligations  recognized  in  other 
comprehensive income (loss) before taxes.

The pension plans’ benefit obligation Net actuarial loss (gain) of $(90) million in 2018 is primarily due to the 
impact  of  an  increase  in  the  discount  rates  utilized  to  calculate  the  benefit  obligation. The  pension  plans’  benefit 
obligation Net actuarial loss (gain) of $40 million in 2017 is primarily due to the impact of a decrease in the discount 
rates utilized to calculate the benefit obligation.

The 2018 benefit obligation Net actuarial loss (gain) of $(17) million for our other postretirement benefit plan is 
primarily due to an increase in the discount rate used to calculate the benefit obligation. The 2017 benefit obligation 
Net actuarial loss (gain) of $11 million for our other postretirement benefit plan is primarily due to a decrease in the 
discount rate used to calculate the benefit obligation.

At December 31, 2018, one of our pension plans had plan assets in excess of its accumulated benefit obligation. 
For our other pension plans, the accumulated benefit obligation of $367 million exceeded plan assets of $326 million. 
All  of  our  pension  plans  had  a  projected  benefit  obligation  in  excess  of  plan  assets  at  December 31,  2018. At 
December 31, 2017, all of our pension plans had a projected benefit obligation and accumulated benefit obligation in 
excess of plan assets.

In addition to the regulatory liabilities included in the previous table, differences in the amount of actuarially 
determined Net periodic benefit cost (credit) for our other postretirement benefit plan and the other postretirement 
benefit costs recovered in rates for Transco and Northwest Pipeline are deferred as a regulatory asset or liability. We 
have regulatory liabilities of $116 million at December 31, 2018 and $108 million at December 31, 2017, related to 
these deferrals. Additionally, Transco recognizes a regulatory liability for rate collections in excess of its amount funded 
to the tax-qualified pension plans. At December 31, 2018 and 2017, these regulatory liabilities were $49 million and 
$33 million, respectively. These pension and other postretirement plans amounts will be reflected in future rates based 
on the rate structures of these gas pipelines.

The mortality assumptions used to determine the benefit obligations for our pension and other postretirement 

benefit plans reflect generational projection mortality tables. 

The assumed health care cost trend rate for 2019 is 7.5 percent. This rate decreases to 4.5 percent by 2026. 

Plan Assets

Plan assets for our pension and other postretirement benefit plans consist primarily of equity and fixed income 
securities including mutual funds and commingled investment funds invested in equity and fixed income securities. 
The plans’ investment policy provides for a strategy in accordance with the Employee Retirement Income Security Act 
(ERISA), which governs the investment of the assets in a diversified portfolio. The plans follow a policy of diversifying 
the  investments  across  various  asset  classes  and  investment  managers.  Additionally,  the  investment  returns  on 
approximately 38 percent of the other postretirement benefit plan assets are subject to income tax; therefore, certain 
investments are managed in a tax efficient manner.

The investment policy for the pension plans includes a general target asset allocation at December 31, 2018, of 25 
percent equity securities and 75 percent fixed income securities. The target allocation includes the investments in equity 
and fixed income mutual funds and commingled investment funds. The investment policy allows for a broad range of 
asset allocations that permit the plans to de-risk in response to changes in the plans’ funded status. 

Equity securities may include U.S. equities and non-U.S. equities. Investment in Williams’ securities or an entity 
in which Williams has a majority ownership is prohibited except where these securities may be owned in a commingled 
investment fund in which the plans’ trusts invest. No more than 5 percent of the total stock portfolio valued at market 
may be invested in the common stock of any one corporation.

Fixed income securities may consist of U.S. as well as international instruments, including emerging markets.  The 
fixed income strategies may invest in government, corporate, asset-backed securities, and mortgage-backed obligations.  
The weighted-average credit rating of the fixed income strategies must be at least “investment grade” including ratings 
by Moody’s and/or Standard & Poor’s.  No more than 5 percent of the total fixed income portfolio may be invested in 

118

 
 
 
 
The Williams Companies, Inc.
Notes to Consolidated Financial Statements – (Continued)

the fixed income securities of any one issuer with the exception of bond index funds and U.S. government guaranteed 
and agency securities.  

The following securities and transactions are not authorized: unregistered securities, commodities or commodity 
contracts,  short  sales  or  margin  transactions,  or  other  leveraging  strategies.  Investment  strategies  using  direct 
investments in derivative securities require approval and, historically, have not been used; however, these instruments 
may be used in mutual funds and commingled investment funds held by the plans’ trusts. Additionally, real estate equity, 
natural resource property, venture capital, leveraged buyouts, and other high-return, high-risk investments are generally 
restricted.

There are no significant concentrations of risk within the plans’ investment securities because of the diversity of 
the types of investments, diversity of the various industries, and the diversity of the fund managers and investment 
strategies. Generally, the investments held in the plans are publicly traded, therefore, minimizing liquidity risk in the 
portfolio.

(1)  The  weighted-average  credit  quality  rating  of  the  fixed  income  security  portfolio  is  investment  grade  with  a 

weighted-average duration of approximately 13 years for 2018 and 12 years for 2017.

(2)  The stated intents of the funds vary based on each commingled fund’s investment objective. These objectives 
generally  include  strategies  to  replicate  or  outperform  various  market  indices.  Certain  standard  withdrawal 
restrictions generally apply, which may include redemption notification period restrictions ranging from 10 days
to 30 days. Additionally, the fund managers retain the right to restrict withdrawals from and/or purchases into the 
funds so as not to disadvantage other investors in the funds. Generally, the funds also reserve the right to make all 
or a portion of the redemption in-kind rather than in cash or a combination of cash and in-kind.

The fair value measurement level within the fair value hierarchy is based on the lowest level of any input that is 

significant to the fair value measurement of an asset.

Shares of the cash management funds and mutual funds are valued at fair value based on published market prices 
as of the close of business on the last business day of the year, which represents the net asset values of the shares held.

The fair values of equity securities traded on U.S. exchanges are derived from quoted market prices as of the close 
of business on the last business day of the year. The fair values of equity securities traded on foreign exchanges are 
also derived from quoted market prices as of the close of business on an active foreign exchange on the last business 
day of the year. However, the valuation requires translation of the foreign currency to U.S. dollars and this translation 
is considered an observable input to the valuation.

122

 
 
 
The Williams Companies, Inc.
Notes to Consolidated Financial Statements – (Continued)

The fair values of all commingled investment funds are determined based on the net asset values per unit of each 
of the funds. The net asset values per unit represent the aggregate values of the funds’ assets at fair value less liabilities, 
divided by the number of units outstanding.

The fair values of fixed income securities, except U.S. Treasury securities, are determined using pricing models. 
These pricing models incorporate observable inputs such as benchmark yields, reported trades, broker/dealer quotes, 
and issuer spreads for similar securities to determine fair value. The U.S. Treasury securities are valued at fair value 
based on closing prices on the last business day of the year reported in the active market in which the security is traded.

There have been no significant changes in the preceding valuation methodologies used at December 31, 2018 and 
2017. Additionally,  there  were  no  transfers  or  reclassifications  of  investments  between  Level  1  and  Level  2  from 
December 2017 to December 2018. If transfers between levels had occurred, the transfers would have been recognized 
as of the end of the period.

Plan Benefit Payments and Employer Contributions

Following are the expected benefits to be paid by the plans. These estimates are based on the same assumptions 
previously  discussed  and  reflect  future  service  as  appropriate.  The  actuarial  assumptions  are  based  on  long-term 
expectations and include, but are not limited to, assumptions as to average expected retirement age and form of benefit 
payment. Actual benefit payments could differ significantly from expected benefit payments if near-term participant 
behaviors differ significantly from the actuarial assumptions.

In 2019, we expect to contribute approximately $60 million to our tax-qualified pension plans and approximately 
$3 million to our nonqualified pension plans, for a total of approximately $63 million, and approximately $6 million
to our other postretirement benefit plans.

Defined Contribution Plan

We also maintain a defined contribution plan for the benefit of substantially all of our employees. Generally, plan 
participants may contribute a portion of their compensation on a pre-tax and after-tax basis in accordance with the 
plan’s  guidelines. We  match  employees’  contributions  up  to  certain  limits.  Our  matching  contributions  charged  to 
expense were $35 million in 2018, $34 million in 2017, and $36 million in 2016.

(1)  Estimated useful life and depreciation rates are presented as of December 31, 2018.  Depreciation rates and estimated 

useful lives for regulated assets are prescribed by the FERC.

Depreciation and amortization expense for Property, plant, and equipment – net was $1.392 billion, $1.389 billion, 

and $1.407 billion in 2018, 2017, and 2016, respectively.

Regulated  Property,  plant,  and  equipment  –  net  includes  approximately  $586  million  and  $626  million  at 
December 31, 2018 and 2017, respectively, related to amounts in excess of the original cost of the regulated facilities 
within our gas pipeline businesses as a result of our prior acquisitions. This amount is being amortized over 40 years
using the straight-line amortization method. Current FERC policy does not permit recovery through rates for amounts 
in excess of original cost of construction.

Asset Retirement Obligations

Our accrued obligations relate to underground storage caverns, offshore platforms and pipelines, fractionation and 
compression facilities, gas gathering well connections and pipelines, and gas transmission pipelines and facilities. At 
the end of the useful life of each respective asset, we are legally obligated to plug storage caverns and remove any 
related  surface  equipment,  to  restore  land  and  remove  surface  equipment  at  gas  processing,  fractionation,  and 
compression facilities, to dismantle offshore platforms and appropriately abandon offshore pipelines, to cap certain 
gathering  pipelines  at  the  wellhead  connection  and  remove  any  related  surface  equipment,  and  to  remove  certain 
components of gas transmission facilities from the ground.

obligations identified from certain Transco land agreements.

(2)  Several factors are considered in the annual review process, including inflation rates, current estimates for removal 
cost, market risk premiums, discount rates, and the estimated remaining useful life of the assets. The 2018 revisions 
reflect changes in removal cost estimates, decreases in the estimated remaining useful life of certain assets and 
increases in the discount rates used in the annual review process. The 2017 revisions reflect changes in removal 
cost estimates and decreases in the estimated remaining useful life of certain assets and discount rates used in the 
annual review process.

The funds Transco collects through a portion of its rates to fund its ARO are deposited into an external trust account 
dedicated to funding its ARO (ARO Trust). (See Note 17 – Fair Value Measurements, Guarantees, and Concentration 
of Credit Risk.) Under its current rate settlement, Transco’s annual funding obligation is approximately $36 million, 
with installments to be deposited monthly.

Other  intangible  assets  primarily  relate  to  gas  gathering,  processing,  and  fractionation  contractual  customer 
relationships recognized in acquisitions. The decrease in the gross carrying amount of other intangible assets during 
2018 is primarily related to the impairment of certain assets located in the Barnett Shale and the deconsolidation of our 
interest in Jackalope (see Note 17 – Fair Value Measurements, Guarantees, and Concentration of Credit Risk and Note 
6 – Investing Activities, respectively). These decreases are the primary reasons for the difference between the change 
in accumulated amortization during 2018 indicated above and the amortization expense for 2018 noted below. Other 
intangible assets are being amortized on a straight-line basis over an initial period of 30 years which represents a portion 
of the term over which the contractual customer relationships are expected to contribute to our cash flows.

We expense costs incurred to renew or extend the terms of our gas gathering, processing, and fractionation contracts 
with customers based on the estimated future revenues during the contract periods (the weighted-average periods prior 
to the next renewal or extension of the associated contractual customer relationships as estimated at the time of the 

125

 
 
 
The Williams Companies, Inc.

acquisition). Although a significant portion of the expected future cash flows associated with these contractual customer 
relationships are dependent on our ability to renew or extend the arrangements beyond the initial contract periods, these 
expected  future  cash  flows  are  significantly  influenced  by  the  scope  and  pace  of  our  producer  customers’  drilling 
programs. Once producer customers’ wells are connected to our gathering infrastructure, their likelihood of switching 
to another provider before the wells are abandoned is reduced due to the significant capital investment required.

The amortization expense related to other intangible assets was $333 million, $347 million, and $356 million in 
2018, 2017, and 2016, respectively. The estimated amortization expense for each of the next five succeeding fiscal 
years is approximately $312 million.

Issuances and retirements

On August 24, 2018, Northwest Pipeline issued $250 million of 4 percent senior unsecured notes to investors in

Other financing obligations

During  the  construction  of  the  Dalton  expansion  project,  Transco  received  funding  from  a  partner  for  its 
proportionate share of construction costs related to its undivided ownership interest in the project. Amounts received 
were recorded within noncurrent liabilities and 100 percent of the costs associated with construction were capitalized 
in our Consolidated Balance Sheet. Upon placing the project in service during the third quarter of 2017, Transco began 
utilizing this partner’s undivided interest in the lateral, including the associated pipeline capacity, and reclassified the 
funding previously received from its partner from noncurrent liabilities to debt to reflect the financing obligation payable 
to its partner over an expected term of 35 years. Amounts related to this financing obligation included in debt within 
our Consolidated Balance Sheet were $260 million and $231 million at December 31, 2018 and 2017, respectively.

During the construction of the Atlantic Sunrise project, Transco received funding from a partner for its proportionate 
share of construction costs related to an undivided ownership interest in certain parts of the project. Amounts received 
were recorded within noncurrent liabilities and 100 percent of the costs associated with construction were capitalized  
in our Consolidated Balance Sheet. Upon placing the project in service during the fourth quarter of 2018, Transco began 
utilizing this partner’s undivided interest in the lateral, including the associated pipeline capacity, and reclassified the 
funding previously received from its partner from noncurrent liabilities to debt to reflect the financing obligation payable 
to its partner over an expected term of 20 years. At December 31, 2018, $807 million related to this financing obligation 
was included in debt within our Consolidated Balance Sheet.

Revolving credit facility

On July 13, 2018, we along with Transco and Northwest Pipeline, the lenders named therein, and an administrative 
agent entered into a new credit agreement (Credit Agreement) with aggregate commitments available of $4.5 billion, 
with up to an additional $500 million increase in aggregate commitments available under certain circumstances. On 
August  10,  2018,  following  the  completion  of  the  WPZ  Merger,  the  Credit Agreement  became  effective  and  we 
terminated both our and WPZ’s existing credit facilities. The maturity date of the new credit facility is August 10, 2023. 
However, the co-borrowers may request up to two extensions of the maturity date each for an additional one-year period 
to allow a maturity date as late as August 10, 2025, under certain circumstances. The Credit Agreement allows for 
swing line loans up to an aggregate of $200 million, subject to available capacity under the new credit facility, and 
letters of credit commitments of $1 billion. Transco and Northwest Pipeline are each able to borrow up to $500 million
under this credit facility to the extent not otherwise utilized by the other co-borrowers. 

The Credit Agreement contains the following terms and conditions:

•  Various covenants may limit, among other things, a borrower’s and its material subsidiaries’ ability to grant 
certain liens supporting indebtedness, merge or consolidate, sell all or substantially all of its assets, make 
certain distributions during an event of default, and enter into certain restrictive agreements.

• 

If an event of default with respect to a borrower occurs under the credit facility, the lenders will be able to 
terminate the commitments and accelerate the maturity of the loans and exercise other rights and remedies.

129

The Williams Companies, Inc.
Notes to Consolidated Financial Statements – (Continued)

•  Other than swing line loans, each time funds are borrowed, the applicable borrower may choose from two 
methods of calculating interest: a fluctuating base rate equal to Citibank N.A.'s alternate base rate plus an 
applicable margin or a periodic fixed rate equal to the London Interbank Offered Rate plus an applicable 
margin. We  are  required  to  pay  a  commitment  fee based  on  the  unused  portion  of  the  credit  facility. The 
applicable margin and the commitment fee are determined by reference to a pricing schedule based on the 
applicable borrower’s senior unsecured long-term debt ratings.

Significant financial covenants under the Credit Agreement require the ratio of debt to EBITDA (earnings before 

interest, taxes, depreciation, and amortization), each as defined in the credit facility, to be no greater than:

• 

• 

• 

5.75 to 1 for each fiscal quarter end through June 30, 2019; 

5.5 to 1 for the fiscal quarters ending September 30, 2019, and December 31, 2019; 

5.0 to 1 for the fiscal quarter ending March 31, 2020, and each subsequent fiscal quarter end, except for the 
fiscal quarter and the two following fiscal quarters in which one or more acquisitions with a total aggregate 
purchase price of $25 million or more has been executed, in which case the ratio of debt to EBITDA is to be 
no greater than 5.5 to 1.

The ratio of debt to capitalization (defined as net worth plus debt) must be no greater than 65 percent for each of 

Transco and Northwest Pipeline.

At December 31, 2018, we are in compliance with these covenants.

Commercial Paper Program

On August 10, 2018, following the consummation of the WPZ Merger, WPZ’s $3 billion commercial paper program 
was discontinued and we entered into a new $4 billion commercial paper program. The maturities of the commercial 
paper notes vary but may not exceed 397 days from the date of issuance. The commercial paper notes are sold under 
customary terms in the commercial paper market and are issued at a discount from par, or, alternatively, are sold at par 
and bear varying interest rates on a fixed or floating basis. The net proceeds of issuances of the commercial paper notes 
are expected to be used to fund planned capital expenditures and for other general corporate purposes. At December 31, 
2018 and 2017, no Commercial paper was outstanding.  At February 19, 2019, no commercial paper was outstanding.

Cash Payments for Interest (Net of Amounts Capitalized)

Cash payments for interest (net of amounts capitalized) were $1.064 billion in 2018, $1.110 billion in 2017, and  

$1.152 billion in 2016.

Note 15 – Stockholders' Equity 

On February 20, 2019, our board of directors approved a regular quarterly dividend of $0.38 per share payable on 

March 25, 2019.

In July 2018, through a wholly owned subsidiary, we contributed 35,000 shares of newly issued Series B Non-
Voting  Perpetual  Preferred  Stock  (Preferred  Stock)  to The Williams  Companies  Foundation,  Inc.  (a  not-for-profit 
corporation)  for  use  in  future  charitable  and  nonprofit  causes. The  charitable  contribution  of  Preferred  Stock  was 
recorded as an expense in the third quarter of 2018. The Preferred Stock was issued for an aggregate value of $35 
million and pays non-cumulative quarterly cash dividends when, as and if declared, at a rate of 7.25 percent per year. 
We paid dividends totaling $1.1 million on the shares of Preferred Stock in 2018. Our certificate of incorporation 
authorizes 30 million shares of Preferred Stock, $1 par value per share.

In January 2017, we issued 65 million shares of common stock in a public offering at a price of $29.00 per share. 
In February 2017, we issued 9.75 million shares of common stock pursuant to the full exercise of the underwriter’s 
option to purchase additional shares. The net proceeds of approximately $2.1 billion were used to purchase newly 
issued common units in WPZ as part of our Financial Repositioning. (See Note 1 – General, Description of Business,

Williams’ Plan Information

On May 17, 2007, our stockholders approved The Williams Companies, Inc. 2007 Incentive Plan (the Plan) that 
provides common-stock-based awards to both employees and nonmanagement directors and reserved 19 million new 
shares for issuance. On May 20, 2010 and May 22, 2014, our stockholders approved amendments and restatements of 
the Plan to increase by 11 million and 10 million, respectively, the number of new shares authorized for making awards 
under the Plan, among other changes. The Plan permits the granting of various types of awards including, but not limited 
to, restricted stock units and stock options. At December 31, 2018, 24 million shares of our common stock were reserved 
for issuance pursuant to existing and future stock awards, of which 12 million shares were available for future grants.

Additionally,  on  May  17, 2007,  our  stockholders  approved  an  Employee  Stock  Purchase  Plan  (ESPP)  which 
authorized up to 2 million new shares of our common stock to be available for sale under the ESPP. On May 22, 2014, 
our stockholders approved an amendment and restatement of the ESPP to increase by 1.6 million the number of new 
shares authorized for sale under the ESPP. Employees purchased 338 thousand shares at an average price of $20.70 
per share during 2018. Approximately 746 thousand shares were available for purchase under the ESPP at December 31, 
2018. 

Operating  and  maintenance  expenses  and  Selling,  general,  and  administrative  expenses  include  equity-based 
compensation expense for the years ended December 31, 2018, 2017, and 2016 of $54 million, $70 million, and $53 
million, respectively. Income tax benefit recognized related to the stock-based compensation expense for the years 
ended December 31, 2018, 2017, and 2016 was $14 million, $17 million, and $20 million, respectively. Measured but 
unrecognized stock-based compensation expense at December 31, 2018, was $56 million, comprised of $4 million
related to stock options and $52 million related to restricted stock units. These amounts are expected to be recognized 
over a weighted-average period of 1.8 years.

The 2018 expected dividend yield is based on the 2018 dividend forecast and the grant-date market price of our 
stock. Our expected future volatility is determined using the historical volatility of our stock and implied volatility on 
our traded options.  Historical volatility is based on the blended 10-year historical volatility of our stock and certain 
peer companies.  The risk-free interest rate is based on the U.S. Treasury Constant Maturity rates as of the grant date. 
The expected life of the option is based on historical exercise behavior and expected future experience.

Performance-based restricted stock units granted under the Plan represent 34 percent of nonvested restricted stock 
units outstanding at December 31, 2018. These grants may be earned at the end of the vesting period based on actual 
performance against a performance target. Based on the extent to which certain financial targets are achieved, vested 
shares may range from zero percent to 200 percent of the original grant amount.

WPZ’s Plan Information

During  2014,  certain  employees  of  the  general  partner  of Access  Midstream  Partners,  L.P.  (ACMP)  received 
equity-based compensation through ACMP’s equity-based compensation program. These awards were converted to 
WPZ equity-based awards in accordance with the terms of the February 2, 2015 merger of Williams Partners L.P. with 
and into Access Midstream Partners, L.P (which was subsequently renamed Williams Partners L.P.). During 2018, no
additional grants of restricted common units were awarded through WPZ’s equity-based compensation programs, and 
all outstanding shares were vested and exercised. Equity-based compensation expense of less than $1 million, $8 
million,  and  $20  million  related  to  WPZ’s  equity-based  compensation  program  is  included  in  Operating  and 
maintenance expenses and Selling, general, and administrative expenses for the years ended December 31, 2018, 2017, 
and 2016, respectively. The total fair value of the restricted common units vested during 2018, 2017, and 2016 was $5 
million, $24 million, and $34 million, respectively. This plan is no longer active.

We use the following methods and assumptions in estimating the fair value of our financial instruments:

Assets and liabilities measured at fair value on a recurring basis

ARO Trust investments: Transco deposits a portion of its collected rates, pursuant to its rate case settlement, into 
an external trust that is specifically designated to fund future asset retirement obligations. The ARO Trust invests in a 
portfolio of actively traded mutual funds that are measured at fair value on a recurring basis based on quoted prices in 
an active market and is reported in Regulatory assets, deferred charges, and other in the Consolidated Balance Sheet. 
Both realized and unrealized gains and losses are ultimately recorded as regulatory assets or liabilities.

Energy derivatives: Energy derivatives include commodity-based exchange-traded contracts and over-the-counter  
contracts, which consist of physical forwards, futures, and swaps that are measured at fair value on a recurring basis. 
The fair value amounts are presented on a gross basis and do not reflect the netting of asset and liability positions 
permitted under the terms of our master netting arrangements. Further, the amounts do not include cash held on deposit 
in margin accounts that we have received or remitted to collateralize certain derivative positions. Energy derivatives 
assets are reported in Other current assets and deferred charges and Regulatory assets, deferred charges, and other in 
the  Consolidated  Balance  Sheet.  Energy  derivatives  liabilities  are  reported  in  Accrued  liabilities  and  Regulatory 
liabilities, deferred income, and other in the Consolidated Balance Sheet.

Notes to Consolidated Financial Statements – (Continued)

Reclassifications of fair value between Level 1, Level 2, and Level 3 of the fair value hierarchy, if applicable, are 
made at the end of each quarter. No transfers between Level 1 and Level 2 occurred during the years ended December 31, 
2018 or 2017. 

Additional fair value disclosures

Long-term debt, including current portion: The disclosed fair value of our long-term debt is determined primarily 
by a market approach using broker quoted indicative period-end bond prices. The quoted prices are based on observable 
transactions in less active markets for our debt or similar instruments.  The fair values of the financing obligations 
associated  with  our  Dalton  lateral  and Atlantic  Sunrise  projects,  which  are  included  within  long-term  debt,  were 
determined using an income approach (see Note 14 – Debt, Banking Arrangements, and Leases).

Guarantees: Guarantees primarily consist of a guarantee we have provided in the event of nonpayment by our 
previously  owned  communications  subsidiary, Williams  Communications  Group  (WilTel),  on  a  lease  performance 
obligation that extends through 2042. Guarantees also include an indemnification related to a disposed operation. 

To estimate the fair value of the WilTel guarantee, an estimated default rate is applied to the sum of the future 
contractual lease payments using an income approach. The estimated default rate is determined by obtaining the average 
cumulative issuer-weighted corporate default rate based on the credit rating of WilTel’s current owner and the term of 
the underlying obligation. The default rate is published by Moody’s Investors Service. The carrying value of the WilTel 
guarantee is reported in Accrued liabilities in the Consolidated Balance Sheet. The maximum potential undiscounted 
exposure  is  approximately  $29  million  at  December 31,  2018.  Our  exposure  declines  systematically  through  the 
remaining term of WilTel’s obligation.

The fair value of the guarantee associated with the indemnification related to a disposed operation was estimated 
using an income approach that considered probability-weighted scenarios of potential levels of future performance.  
The terms of the indemnification do not limit the maximum potential future payments associated with the guarantee. 
The carrying value of this guarantee is reported in Regulatory liabilities, deferred income, and other in the Consolidated 
Balance Sheet. 

We are required by our revolving credit agreement to indemnify lenders for certain taxes required to be withheld 
from payments due to the lenders and for certain tax payments made by the lenders. The maximum potential amount 
of future payments under these indemnifications is based on the related borrowings and such future payments cannot 
currently be determined. These indemnifications generally continue indefinitely unless limited by the underlying tax 
regulations and have no carrying value. We have never been called upon to perform under these indemnifications and 
have no current expectation of a future claim.

______________
(1)  Relates to our gathering operations in the Barnett Shale.  Certain of our contractual gathering rates, primarily 
those in the Barnett Shale, are based on a percentage of the New York Mercantile Exchange (NYMEX) natural 
gas prices.  During the fourth quarter of 2018, we determined there was a sustained decline in the forward price 
curves for natural gas.  During this same period, a large producer customer in the Barnett Shale removed their 
remaining drilling rig.  These factors gave rise to an impairment evaluation of these assets, which incorporated 
management’s projections of future drilling activity and gathering rates, taking into consideration the information 
previously noted as well as recently available information regarding producer drilling cost assumptions in the 
basin.  The resulting estimate of future undiscounted cash flows was less than our carrying value, necessitating 
the estimation of the fair value of these assets.  To arrive at the fair value, we utilized an income approach with 
a discount rate of 8.5 percent, reflecting an estimated cost of capital and risks associated with the underlying 
assets.

(2)  Relates to certain idle pipelines.  The estimated fair value was determined by a market approach incorporating 
information derived from bids received for these assets, which we marketed for sale together with certain other 
assets.  These inputs resulted in a fair value measurement within Level 2 of the fair value hierarchy.  We sold 
these assets in the fourth quarter of 2018.   (See Note 3 – Divestitures.)   

(3)  Relates to certain gathering operations in the Mid-Continent region. During the third quarter of 2017, we received 
solicitations  and  engaged  in  negotiations  for  the  sale  of  certain  of  these  assets  which  led  to  our  impairment 
evaluation. The estimated fair value was determined using an income approach and incorporated market inputs 
based on ongoing negotiations for a potential sale of a portion of the underlying assets.  For the income approach, 
we utilized a discount rate of 10.2 percent, reflecting an estimated cost of capital and risks associated with the 
underlying assets.

(4)  Relates to certain gathering operations in the Marcellus South region resulting from an anticipated decline in 
future volumes following a third-quarter 2017 shut-in by the primary producer.  The estimated fair value was 
determined by the income approach utilizing a discount rate of 11.1 percent, reflecting an estimated cost of capital 
and risks associated with the underlying assets.

(5)  Relates to an NGL pipeline near the Houston Ship Channel region which we anticipated would be underutilized 
for the foreseeable future.  The estimated fair value was primarily determined by using a market approach based 
on our analysis of observable inputs in the principal market.  We sold these assets in the fourth quarter of 2018.  
(See Note 3 – Divestitures.)

(6)  Relates primarily to project development costs associated with an olefins pipeline project in the Gulf Coast region, 
the likelihood of completion we considered remote.  The estimated fair value of the remaining pipe and equipment 
considered a market approach based on our analysis of observable inputs in the principal market, as well as an 
estimate of replacement cost.  We sold these assets in the fourth quarter of 2018.  (See Note 3 – Divestitures.)

138

The Williams Companies, Inc.
Notes to Consolidated Financial Statements – (Continued)

(7)  Relates to our Canadian operations. We designated these operations as held for sale as of June 30, 2016. As a 
result, we measured the fair value of the disposal group, resulting in an impairment charge. The estimated fair 
value was determined by a market approach based primarily on inputs received in the marketing process and 
reflected our estimate of the potential assumed proceeds. We disposed of our Canadian operations through a sale 
during the third quarter of 2016.   (See Note 3 – Divestitures.)

(8)  Relates to certain gathering assets within the Mid-Continent region. The estimated fair value was determined by 

a market approach based on our analysis of observable inputs in the principal market. 

(9)  Reflects multiple individually insignificant impairments and write-downs of other certain assets that may no 
longer be in use or are surplus in nature for which the fair value was determined to be lower than the carrying 
value. 

(10)  Relates to Northeast G&P’s equity-method investment in UEOM.  The estimated fair value was determined by 

a market approach based on our analysis of inputs in the principal market.

(11)  Relates to West’s previously held interest in Ranch Westex and multiple, currently held Appalachia Midstream 
Investments at Northeast G&P. The historical carrying value of these equity-method investments was initially 
recorded based on estimated fair value during the third quarter of 2014 in conjunction with the acquisition of 
ACMP. We estimated the fair value of these Appalachia Midstream Investments using an income approach based 
on expected future cash flows and appropriate discount rates. The determination of estimated future cash flows 
involved significant assumptions regarding gathering volumes, rates, and related capital spending. The discount 
rate utilized for the Appalachia Midstream Investments evaluation was 10.2 percent and reflected an estimated 
cost of capital as impacted by market conditions and risks associated with the underlying businesses. In addition 
to  utilizing  an  income  approach,  we  also  considered  a  market  approach  for  certain Appalachia  Midstream 
Investments and Ranch Westex based on an agreement reached in February 2017 to exchange our interests in 
DBJV and Ranch Westex for additional interests in certain Appalachia Midstream Investments and cash. (See 
Note 6 – Investing Activities.)

(12)  Relates to West’s previously held interest in DBJV and Northeast G&P’s currently held equity-method investment 
in Laurel Mountain. Our carrying values in these equity-method investments had been written down to fair value 
at December 31, 2015. Our first-quarter 2016 analysis reflected higher discount rates for both of these equity-
method investments, along with lower natural gas prices for Laurel Mountain. We estimated the fair value of 
these equity-method investments using an income approach based on expected future cash flows and appropriate 
discount  rates. The  determination  of  estimated  future  cash  flows  involved  significant  assumptions  regarding 
gathering volumes and related capital spending. Discount rates utilized ranged from 13.0 percent to 13.3 percent
and reflected increases in the estimated cost of capital, revised estimates of expected future cash flows, and risks 
associated with the underlying businesses.

Notes to Consolidated Financial Statements – (Continued)

Customers  include  producers,  distribution  companies,  industrial  users,  gas  marketers,  and  pipelines  primarily 
located in the continental United States. As a general policy, collateral is not required for receivables, but customers’ 
financial condition and credit worthiness are evaluated regularly. Based upon this evaluation, we may obtain collateral 
to  support  receivables.  As  of  December 31,  2018  and  2017,  Chesapeake  Energy  Corporation,  and  its  affiliates 
(Chesapeake), a customer primarily within our Northeast G&P and West segments, accounted for $65 million and $176 
million,  respectively,  of  the  consolidated Trade  accounts  and  other  receivables  balances. The  increase  in  Other  is 
primarily due to an increase in our federal income tax receivable.

Revenues

In 2018, 2017, and 2016, Chesapeake accounted for 8 percent, 10 percent, and 14 percent, respectively, of our 

consolidated revenues. 

Note 18 – Contingent Liabilities and Commitments

Reporting of Natural Gas-Related Information to Trade Publications

Direct and indirect purchasers of natural gas in various states filed individual and class actions against us, our 
former affiliate WPX Energy, Inc. (WPX) and its subsidiaries, and others alleging the manipulation of published gas 
price indices and seeking unspecified amounts of damages. Such actions were transferred to the Nevada federal district 
court for consolidation of discovery and pre-trial issues. We have agreed to indemnify WPX and its subsidiaries related 
to this matter.

In the individual action, filed by Farmland Industries Inc. (Farmland), the court issued an order on May 24, 2016, 
granting one of our co-defendant’s motion for summary judgment as to Farmland’s claims. On January 5, 2017, the 
court extended such ruling to us, entering final judgment in our favor. Farmland appealed. On March 27, 2018, the 
appellate court reversed the district court’s grant of summary judgment, and on April 10, 2018, the defendants filed a 
petition for rehearing with the appellate court, which was denied on May 9, 2018. The case has been remanded to the 
Nevada federal district court.

In the putative class actions, on March 30, 2017, the court issued an order denying the plaintiffs’ motions for class 
certification. On June 13, 2017, the United States Court of Appeals for the Ninth Circuit granted the plaintiffs’ petition 
for permission to appeal the order. On August 6, 2018, the Ninth Circuit reversed the order denying class certification 
and remanded the case to the Nevada federal district court.

Because of the uncertainty around the remaining pending unresolved issues, we cannot reasonably estimate a range 
of potential exposure at this time. However, it is reasonably possible that the ultimate resolution of these actions and 
our related indemnification obligation could result in a potential loss that may be material to our results of operations. 
In connection with this indemnification, we have an accrued liability balance associated with this matter, and as a result, 
have exposure to future developments.

Alaska Refinery Contamination Litigation

We are involved in litigation arising from our ownership and operation of the North Pole Refinery in North Pole, 
Alaska, from 1980 until 2004, through our wholly owned subsidiaries, Williams Alaska Petroleum Inc. (WAPI) and 
MAPCO Inc. We sold the refinery to Flint Hills Resources Alaska, LLC (FHRA), a subsidiary of Koch Industries, Inc., 
in 2004. The litigation involves three cases, with filing dates ranging from 2010 to 2014. The actions arise from sulfolane 
contamination allegedly emanating from the refinery. A putative class action lawsuit was filed by James West in 2010 
naming us, WAPI, and FHRA as defendants. We and FHRA filed claims against each other seeking, among other things, 
contractual indemnification alleging that the other party caused the sulfolane contamination. In 2011, we and FHRA 
settled the claim with James West. Certain claims by FHRA against us were resolved by the Alaska Supreme Court in 
our favor. FHRA’s claims against us for contractual indemnification and statutory claims for damages related to off-
site sulfolane remain pending. The State of Alaska filed its action in March 2014, seeking damages. The City of North 
Pole (North Pole) filed its lawsuit in November 2014, seeking past and future damages, as well as punitive damages. 

140

The Williams Companies, Inc.
Notes to Consolidated Financial Statements – (Continued)

Both we and WAPI asserted counterclaims against the State of Alaska and North Pole, and cross-claims against FHRA. 
FHRA has also filed cross-claims against us.

The underlying factual basis and claims in the cases are similar and may duplicate exposure. As such, in February 
2017, the three cases were consolidated into one action in state court containing the remaining claims from the James 
West case and those of the State of Alaska and North Pole. Several trial dates encompassing all three cases have been 
scheduled and stricken; we are awaiting a new trial date. Due to the ongoing assessment of the level and extent of 
sulfolane contamination, the lack of an articulated cleanup level for sulfolane, and the lack of a concrete remedial 
proposal and cost estimate, we are unable to estimate a range of exposure to the State of Alaska or North Pole at this 
time. We currently estimate that our reasonably possible loss exposure to FHRA could range from an insignificant 
amount up to $32 million, although uncertainties inherent in the litigation process, expert evaluations, and jury dynamics 
might cause our exposure to exceed that amount.

Independent of the litigation matter described in the preceding paragraphs, in 2013, the Alaska Department of 
Environmental Conservation indicated that it views FHRA and us as responsible parties, and that it intends to enter a 
compliance order to address the environmental remediation of sulfolane and other possible contaminants including 
cleanup work outside the refinery’s boundaries. To date, no compliance order has been issued. Due to the ongoing 
assessment of the level and extent of sulfolane contamination, the ultimate cost of remediation and division of costs 
among the potentially responsible parties, and the previously described separate litigation, we are unable to estimate a 
range of exposure at this time.

Royalty Matters

Certain  of  our  customers,  including  one  major  customer,  have  been  named  in  various  lawsuits  alleging 
underpayment of royalties and claiming, among other things, violations of anti-trust laws and the Racketeer Influenced 
and Corrupt Organizations Act. We have also been named as a defendant in certain of these cases filed in Pennsylvania 
based  on  allegations  that  we  improperly  participated  with  that  major  customer  in  causing  the  alleged  royalty 
underpayments. We believe that the claims asserted are subject to indemnity obligations owed to us by that major 
customer. That  customer  has  reached  a  tentative  settlement  to  resolve  substantially  all  Pennsylvania  royalty  cases 
pending, which settlement would apply to both the customer and us. The settlement as reported would not require any 
contribution from us.

Litigation Against Energy Transfer and Related Parties

On April 6, 2016, we filed suit in Delaware Chancery Court against Energy Transfer Equity, L.P. (Energy Transfer) 
and LE GP, LLC (the general partner for Energy Transfer) alleging willful and material breaches of the Agreement and 
Plan of Merger (ETE Merger Agreement) with Energy Transfer resulting from the private offering by Energy Transfer 
on March 8, 2016, of Series A Convertible Preferred Units (Special Offering) to certain Energy Transfer insiders and 
other accredited investors. The suit seeks, among other things, an injunction ordering the defendants to unwind the 
Special Offering and to specifically perform their obligations under the ETE Merger Agreement. On April 19, 2016, 
we filed an amended complaint seeking the same relief. On May 3, 2016, Energy Transfer and LE GP, LLC filed an 
answer and counterclaims.

On May 13, 2016, we filed a separate complaint in Delaware Chancery Court against Energy Transfer, LE GP, 
LLC, and the other Energy Transfer affiliates that are parties to the ETE Merger Agreement, alleging material breaches 
of the ETE Merger Agreement for failing to cooperate and use necessary efforts to obtain a tax opinion required under 
the ETE Merger Agreement (Tax Opinion) and for otherwise failing to use necessary efforts to consummate the merger 
under the ETE Merger Agreement wherein we would be merged with and into the newly formed Energy Transfer Corp 
LP (ETC) (ETC Merger). The suit sought, among other things, a declaratory judgment and injunction preventing Energy 
Transfer from terminating or otherwise avoiding its obligations under the ETE Merger Agreement due to any failure 
to obtain the Tax Opinion.

141

The Williams Companies, Inc.
Notes to Consolidated Financial Statements – (Continued)

The Court of Chancery coordinated the Special Offering and Tax Opinion suits. On May 20, 2016, the Energy 
Transfer defendants filed amended affirmative defenses and verified counterclaims in the Special Offering and Tax 
Opinion  suits,  alleging  certain  breaches  of  the  ETE  Merger Agreement  by  us  and  seeking,  among  other  things,  a 
declaration that we were not entitled to specific performance, that Energy Transfer could terminate the ETC Merger, 
and that Energy Transfer is entitled to a $1.48 billion termination fee. On June 24, 2016, following a two-day trial, the 
court issued a Memorandum Opinion and Order denying our requested relief in the Tax Opinion suit. The court did not 
rule on the substance of our claims related to the Special Offering or on the substance of Energy Transfer’s counterclaims. 
On June 27, 2016, we filed an appeal of the court’s decision with the Supreme Court of Delaware, seeking reversal and 
remand to pursue damages. On March 23, 2017, the Supreme Court of Delaware affirmed the Court of Chancery’s 
ruling. On March 30, 2017, we filed a motion for reargument with the Supreme Court of Delaware, which was denied 
on April 5, 2017.

On September 16, 2016, we filed an amended complaint with the Court of Chancery seeking damages for breaches 
of the ETE Merger Agreement by defendants.  On September 23, 2016, Energy Transfer filed a second amended and 
supplemental affirmative defenses and verified counterclaim with the Court of Chancery seeking, among other things, 
payment of the $1.48 billion termination fee due to our alleged breaches of the ETE Merger Agreement. On December 1, 
2017, the court granted our motion to dismiss certain of Energy Transfer’s counterclaims, including its claim seeking 
payment of the $1.48 billion termination fee. On December 8, 2017, Energy Transfer filed a motion for reargument, 
which the Court of Chancery denied on April 16, 2018. Although the Court of Chancery scheduled trial for May 20 
through May 24, 2019, the parties anticipate trial will be re-scheduled for a later date.

Environmental Matters

We are a participant in certain environmental activities in various stages including assessment studies, cleanup 
operations, and/or remedial processes at certain sites, some of which we currently do not own. We are monitoring these 
sites in a coordinated effort with other potentially responsible parties, the U.S. Environmental Protection Agency (EPA), 
or other governmental authorities. We are jointly and severally liable along with unrelated third parties in some of these 
activities and solely responsible in others. Certain of our subsidiaries have been identified as potentially responsible 
parties at various Superfund and state waste disposal sites. In addition, these subsidiaries have incurred, or are alleged 
to have incurred, various other hazardous materials removal or remediation obligations under environmental laws. As 
of December 31, 2018, we have accrued liabilities totaling $35 million for these matters, as discussed below. Estimates 
of the most likely costs of cleanup are generally based on completed assessment studies, preliminary results of studies, 
or our experience with other similar cleanup operations. At December 31, 2018, certain assessment studies were still 
in process for which the ultimate outcome may yield different estimates of most likely costs. Therefore, the actual costs 
incurred will depend on the final amount, type, and extent of contamination discovered at these sites, the final cleanup 
standards mandated by the EPA or other governmental authorities, and other factors.

The EPA and various state regulatory agencies routinely promulgate and propose new rules and issue updated 
guidance to existing rules. These rulemakings include, but are not limited to, rules for reciprocating internal combustion 
engine maximum achievable control technology, air quality standards for one-hour nitrogen dioxide emissions, and 
volatile organic compound and methane new source performance standards impacting design and operation of storage 
vessels, pressure valves, and compressors. The EPA previously issued its rule regarding National Ambient Air Quality 
Standards for ground-level ozone. We are monitoring the rule’s implementation as it will trigger additional federal and 
state regulatory actions that may impact our operations. Implementation of the regulations is expected to result in 
impacts to our operations and increase the cost of additions to Property, plant, and equipment – net in the Consolidated 
Balance Sheet for both new and existing facilities in affected areas. We are unable to reasonably estimate the cost of 
additions that may be required to meet the regulations at this time due to uncertainty created by various legal challenges 
to these regulations and the need for further specific regulatory guidance.

Continuing operations

Our interstate gas pipelines are involved in remediation activities related to certain facilities and locations for 
polychlorinated biphenyls, mercury, and other hazardous substances. These activities have involved the EPA and various 

142

The Williams Companies, Inc.
Notes to Consolidated Financial Statements – (Continued)

state environmental authorities, resulting in our identification as a potentially responsible party at various Superfund 
waste sites. At December 31, 2018, we have accrued liabilities of $6 million for these costs. We expect that these costs 
will be recoverable through rates.

We also accrue environmental remediation costs for natural gas underground storage facilities, primarily related 
to soil and groundwater contamination. At December 31, 2018, we have accrued liabilities totaling $7 million for these 
costs.

Former operations

We have potential obligations in connection with assets and businesses we no longer operate. These potential 
obligations  include  remediation  activities  at  the  direction  of  federal  and  state  environmental  authorities  and  the 
indemnification of the purchasers of certain of these assets and businesses for environmental and other liabilities existing 
at the time the sale was consummated. Our responsibilities relate to the operations of the assets and businesses described 
below.

•  Former agricultural fertilizer and chemical operations and former retail petroleum and refining operations;

•  Former petroleum products and natural gas pipelines;

•  Former petroleum refining facilities;

•  Former exploration and production and mining operations;

•  Former electricity and natural gas marketing and trading operations.

At December 31, 2018, we have accrued environmental liabilities of $22 million related to these matters.

Other Divestiture Indemnifications

Pursuant to various purchase and sale agreements relating to divested businesses and assets, we have indemnified 
certain purchasers against liabilities that they may incur with respect to the businesses and assets acquired from us. 
The indemnities provided to the purchasers are customary in sale transactions and are contingent upon the purchasers 
incurring liabilities that are not otherwise recoverable from third parties. The indemnities generally relate to breach of 
warranties, tax, historic litigation, personal injury, property damage, environmental matters, right of way, and other 
representations that we have provided.

At December 31, 2018, other than as previously disclosed, we are not aware of any material claims against us 
involving the indemnities; thus, we do not expect any of the indemnities provided pursuant to the sales agreements to 
have a material impact on our future financial position. Any claim for indemnity brought against us in the future may 
have a material adverse effect on our results of operations in the period in which the claim is made.

In addition to the foregoing, various other proceedings are pending against us which are incidental to our operations, 
none of which are expected to be material to our expected future annual results of operations, liquidity, and financial 
position.

Summary

We  have  disclosed  our  estimated  range  of  reasonably  possible  losses  for  certain  matters  above,  as  well  as  all 
significant matters for which we are unable to reasonably estimate a range of possible loss. We estimate that for all 
other matters for which we are able to reasonably estimate a range of loss, our aggregate reasonably possible losses 
beyond amounts accrued are immaterial to our expected future annual results of operations, liquidity, and financial 
position. These calculations have been made without consideration of any potential recovery from third parties.

Commitments

Commitments for construction and acquisition of property, plant, and equipment are approximately $480 million

at December 31, 2018.

 Note 19 – Segment Disclosures 

Our reportable segments are Northeast G&P, Atlantic-Gulf, and West. All remaining business activities are included 
in Other. (See Note 1 – General, Description of Business, Basis of Presentation, and Summary of Significant Accounting 
Policies.)

Performance Measurement

We  evaluate  segment  operating  performance  based  upon  Modified  EBITDA  (earnings  before  interest,  taxes, 
depreciation, and amortization). This measure represents the basis of our internal financial reporting and is the primary 
performance measure used by our chief operating decision maker in measuring performance and allocating resources 
among our reportable segments. Intersegment revenues primarily represent the sale of NGLs from our natural gas 
processing plants to our marketing business.

We define Modified EBITDA as follows:

•  Net income (loss) before:

  Provision (benefit) for income taxes;

Interest incurred, net of interest capitalized;

  Equity earnings (losses);

  Gain on remeasurement of equity-method investment;

Impairment of equity-method investments; 

  Other investing income (loss) – net;

  Depreciation and amortization expenses;

  Accretion expense associated with asset retirement obligations for nonregulated operations.

•  This measure is further adjusted to include our proportionate share (based on ownership interest) of Modified 
EBITDA from our equity-method investments calculated consistently with the definition described above.

Item 9A.  Controls and Procedures

Disclosure Controls and Procedures

Our management, including our Chief Executive Officer and Chief Financial Officer, does not expect that our 
disclosure controls and procedures (as defined in Rules 13a - 15(e) and 15d - 15(e) of the Securities Exchange Act) 
(Disclosure Controls) will prevent all errors and all fraud. A control system, no matter how well conceived and operated, 
can provide only reasonable, not absolute, assurance that the objectives of the control system are met. 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. Because of the inherent limitations in all control systems, no evaluation of controls 
can provide absolute assurance that all control issues and instances of fraud, if any, within the company have been 
detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that 
breakdowns can occur because of simple error or mistake. Additionally, controls can be circumvented by the individual 
acts of some persons, by collusion of two or more people, or by management override of the control. The design of 
any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there 
can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. 
Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur 
and not be detected. We monitor our Disclosure Controls and make modifications as necessary; our intent in this regard 
is that the Disclosure Controls will be modified as systems change and conditions warrant.

Evaluation of Disclosure Controls and Procedures

An evaluation of the effectiveness of the design and operation of our Disclosure Controls was performed as of the 
end of the period covered by this report. This evaluation was performed under the supervision and with the participation 
of our management, including our Chief Executive Officer and Chief Financial Officer. Based upon that evaluation, 
our Chief Executive Officer and Chief Financial Officer concluded that these Disclosure Controls are effective at a 
reasonable assurance level.

Changes in Internal Control Over Financial Reporting

There have been no changes during the fourth quarter of 2018 that have materially affected, or are reasonably 

likely to materially affect, our Internal Control over Financial Reporting.

Management’s Annual Report on Internal Control over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting (as 
defined in Rules 13a - 15(f) and 15d - 15(f) under the Securities Exchange Act of 1934). Our internal control over 
financial reporting is designed to provide reasonable assurance to our management and board of directors regarding 
the preparation and fair presentation of financial statements in accordance with accounting principles generally accepted 
in the United States. Our internal control over financial reporting includes those policies and procedures that (i) pertain 
to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions 
of our assets; (ii) provide reasonable assurance that transactions are recorded as to permit preparation of financial 
statements in accordance with generally accepted accounting principles, and that our receipts and expenditures are 
being made only in accordance with authorization of our management and board of directors; and (iii) provide reasonable 
assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that 
could have a material effect on our financial statements.

All internal control systems, no matter how well designed, have inherent limitations including the possibility of 
human error and the circumvention or overriding of controls. Therefore, even those systems determined to be effective 
can provide only reasonable assurance with respect to financial statement preparation and presentation.

150

Under the supervision and with the participation of our management, including our Chief Executive Officer and 
Chief Financial Officer, we assessed the effectiveness of our internal control over financial reporting as of December 31, 
2018, based on the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission 
(COSO)  in  Internal  Control — Integrated  Framework  (2013).  Based  on  our  assessment,  we  concluded  that,  as  of 
December 31, 2018, our internal control over financial reporting was effective.

Ernst & Young  LLP,  our  independent  registered  public  accounting  firm,  has  audited  our  internal  control  over 

financial reporting, as stated in their report which is included in this Annual Report on Form 10-K.

Report of Independent Registered Public Accounting Firm 

The Stockholders and the Board of Directors of
The Williams Companies, Inc.

Opinion on Internal Control Over Financial Reporting
We have audited The Williams Companies, Inc.’s internal control over financial reporting as of December 31, 2018, 
based  on  criteria  established  in  Internal  Control-Integrated  Framework  issued  by  the  Committee  of  Sponsoring 
Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, The Williams 
Companies, Inc. (the Company) maintained, in all material respects, effective internal control over financial reporting 
as of December 31, 2018, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United 
States) (PCAOB), the consolidated balance sheet of the Company as of December 31, 2018 and 2017, and the related 
consolidated statements of operations, comprehensive income (loss), changes in equity and cash flows for each of the 
three years in the period ended December 31, 2018, and the related notes and the financial statement schedule listed 
in the index at Item 15(a) and our report dated February 21, 2019 expressed an unqualified opinion thereon.

Basis for Opinion
The Company’s management is responsible for maintaining effective internal control over financial reporting and for 
its  assessment  of  the  effectiveness  of  internal  control  over  financial  reporting  included  in  the  accompanying 
Management’s Annual Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion 
on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered 
with the PCAOB and are required to be independent with respect to the 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 audit in accordance with the standards of the PCAOB. Those standards require that we plan and 
perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was 
maintained in all material respects. 

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a 
material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the 
assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that 
our audit provides a reasonable basis for our opinion.

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

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