Dear Fellow  
Stakeholder,

Energy for You summarizes why our business is centered on our 
customers and communities. Our employees give their best each 
day to deliver the energy that makes lives more comfortable, 
productive, and enjoyable. 

We have a commitment to be Always There – providing reliable 
electricity and natural gas to our customers. We make significant 
investments for safety, reliability, and the growing energy 
demands of our service territory. Over the next five years, we 
plan to spend nearly $7 billion in capital. 

To put customers in control, we’ve made significant investments 
in technology. In 2017, customers will be introduced to our new 
online preference center, which will give them even more options 
for when and how we contact them regarding their billing 
options, program promotions, and usage. 

To make life better, we endeavor to ensure the safety and 
reliability of our systems. By keeping the lights on and the 
natural gas flowing, we help our customers enjoy their lives. For 
example, we invested in drive-by leak detection tools, which 
enable us to check more miles of pipe than ever before to help 
maintain the safety of our natural gas delivery system. 

To build stronger communities, we volunteer our time and give 
our support to make a positive difference in our communities.  
In 2016, our employees donated nearly 5,000 units of blood, 
which is enough to impact more than 14,000 lives. Giving back  
is core to who we are as a company. 

2016: A year of strong growth

We had a strong year in 2016, marked by a dividend increase,  
growth in earnings, and acquisitions. Our results were driven  
by a number of factors, including solid customer growth  
in both our electric and natural gas utilities with more than  
90,000 additional meters. 

“ We had a strong year  
in 2016, marked by a  
dividend increase,  
growth in earnings,  
and acquisitions.”

Total shareholder return for the company in 2016 was  
40.88 percent, outperforming the S&P 500 Utilities Index  
of 16.29 percent and the S&P 500 Index of 11.96 percent. 

In early 2017, we raised our dividend for the 12th consecutive 
year when our board declared a regular quarterly cash dividend 
of 26.75 cents per share. This represents a 4 percent increase 
from the previous quarterly dividend and, when annualized, 
equates to $1.07 per share. 

CenterPoint Energy reported 2016 net income of $432 million,  
or $1.00 per diluted share. Our annual adjusted earnings, using 
the same basis as our guidance, were $501 million, or $1.16 per 
diluted share(1). The majority of earnings, $380 million, were  
from utility operations, while $121 million were related to our 
investments in Enable Midstream, a publicly traded master 
limited partnership that owns, operates, and develops strategically 
located natural gas and crude oil infrastructure assets. 

We continue to look for additional opportunities to grow 
earnings. CenterPoint Energy Services (CES), our unregulated 
energy services business, completed the purchase of Continuum 
Retail Energy Services last year and closed on the Atmos Energy 
Marketing transaction in January 2017. These acquisitions provide 
CES with the kind of scale, geographic reach, and expanded 
capabilities that will enable it to grow. Accessing more markets 
and efficiently increasing our customer base, our retail energy 
business now operates in 33 states and serves approximately 
100,000 customers. 

The strength of our utilities

CenterPoint Energy’s long-term success is driven by the 
disciplined execution of our strategy to Operate, Serve and 
Grow. By addressing the needs of our growing service territories 
through capital investment, we are increasing our rate base, 
which helps drive our financial performance. 

The electric transmission & distribution segment had an 
excellent year. Earnings growth was driven primarily through 
rate relief from investments needed to serve our increasing 
customer base, customer growth, and higher equity return. 

Building the infrastructure to serve the energy needs of today 
and tomorrow remains a priority. Scheduled to be in service  
by summer 2018, the Brazos Valley Connection is a 60-mile,  
345-kilovolt electric transmission line in Texas that will run from 
Harris County to Grimes County, where it connects to the 
northern portion of a similar project.

Our continuing investment in intelligent grid technology 
increases reliability, reduces average restoration time, saves 
consumers money, and drives innovation. In 2016, we improved 
electric reliability 34 percent on intelligent grid circuits. Through 
the intelligent grid, customers have avoided nearly 200 million 
outage minutes since 2011. Smart meters save consumers more 
than $20 million per year in eliminated fees through service 
automation. This technology has also saved more than 1.6 million 
gallons of fuel, preventing nearly 15,000 tons of CO2 emissions.

The natural gas distribution segment also had a strong year. 
Earnings growth was driven by rate relief and customer growth. 

Last year, we filed with municipal and state regulatory authorities 
to change natural gas distribution rates for Houston-area cus- 
tomers. Our objective in this filing is for customers throughout 
Houston and surrounding areas to pay a uniform rate for the cost 
of service and the cost of gas. We also implemented new rates in 
Arkansas and Minnesota. The purpose of these rate proceedings 
is to allow us to earn a reasonable return for the hundreds of 
million dollars spent each year in our service territories to 
accommodate growth and make our system safe and reliable. 

Continued future growth 

Through the leadership of our board of directors, we remain 
dedicated to delivering long-term value to our shareholders by 
growing earnings and providing a competitive dividend. 

In 2017, we expect increased earnings from continued utility 
customer growth, rate relief, our competitive retail business,  
and our investment in Enable Midstream. We also expect lower 
interest expense. We expect these items collectively to result  
in solid growth year over year. 

Together, our electric and natural gas utilities are expected to 
invest $1.5 billion in capital in 2017. Our electric business anticipates 
capital spending of $922 million to support sustained customer 
growth. Our natural gas distribution business plans to invest  
$534 million of capital to accommodate ongoing growth and 
pipeline replacement needs.

Our dedicated employees 

At the heart of CenterPoint Energy are our employees, who 
demonstrate our values of safety, integrity, accountability, 
initiative and respect.

We also received several environmental awards in 2016, 
including the Climate Leadership Award and ENERGY STAR 
Partners of the Year award, both from the U.S. Environmental 
Protection Agency. 

Our energy-efficiency efforts span across commercial, residential, 
and low-income programs for both electric and natural gas 
consumers. In 2016, approximately 170,000 megawatt hours of 
energy were saved. Rebates from our conservation improvements 
led to customers saving nearly $18 million – the equivalent of the 
annual energy usage of about 27,000 homes.

Last year, we conducted an employee survey, which reflected 
high levels of pride, commitment, and employee engagement. 
Studies have demonstrated that an engaged workforce can have 
a significant effect on financial and operational results as well  
as higher customer satisfaction.

Our successes and awards reflect the commitment and talent  
of our dedicated workforce.

Our Energy for You

Your investment in CenterPoint Energy supports our company, 
our employees, our communities and, ultimately, energy for you. 
Thank you for your confidence in our company, leadership, and 
vision to lead the nation in delivering energy, service, and value.

Sincerely,

MILTON CARROLL  

Executive Chairman 
of the Board

Safety of our employees, delivery systems and the public is  
our priority. CenterPoint Energy was placed in the top quartile 
for Edison Electric Institute and American Gas Association 
safety rankings in 2016. However, we also had several serious 
safety incidents that reinforced our commitment to working 
safely and continuing to improve our safety programs and 
performance. Our overall approach to safety performance is 
focused on behavior-based safety programs and a commitment 
to sustaining a strong safety culture.  

We have been honored with several prestigious awards thanks 
to the efforts of our employees. For example, we received the 
Emergency Recovery Award from the Edison Electric Institute 
for our power restoration efforts after severe flooding hit 
Houston in April 2016. Our crews devoted nearly 16,000 hours  
to this recovery, and our intelligent grid saved 26 million outage 
minutes during this event. 

Additionally, we’re proud to have been recognized for our 
customer service. In 2016, we were named the top Texas Electric 
Transmission and Distribution Service Provider (TDSP) in 
customer satisfaction by Cogent Energy Reports in the Texas 
TDSP Trusted Brand & Customer Engagement Study.

Business

Overview

PART I

OUR BUSINESS

We are a public utility holding company. Our operating subsidiaries own and operate electric transmission and distribution 
and natural gas distribution facilities, supply natural gas to commercial and industrial customers and electric and natural gas utilities 
and own interests in Enable as described below. Our indirect, wholly-owned subsidiaries include:

•  Houston Electric, which engages in the electric transmission and distribution business in the Texas Gulf Coast area that 

includes the city of Houston; 

•  CERC Corp., which owns and operates natural gas distribution systems in six states; and

•  CES, which obtains and offers competitive variable and fixed-price physical natural gas supplies and services primarily 

to commercial and industrial customers and electric and natural gas utilities in 31 states. 

As of December 31, 2016, we also owned an aggregate of 14,520,000 Series A Preferred Units in Enable, which owns, operates 
and develops natural gas and crude oil infrastructure assets, and CERC Corp. owned approximately 54.1% of the limited partner 
interests in Enable.

Our  reportable  business  segments  are  Electric  Transmission  &  Distribution,  Natural  Gas  Distribution,  Energy  Services,

Electric Transmission & Distribution

Houston Electric is a transmission and distribution electric utility that operates wholly within the state of Texas. Neither 
Houston Electric nor any other subsidiary of CenterPoint Energy makes direct retail or wholesale sales of electric energy or owns 
or operates any electric generating facilities.

1

 
Electric Transmission

On behalf of REPs, Houston Electric delivers electricity from power plants to substations, from one substation to another and 
to retail electric customers taking power at or above 69 kilovolts in locations throughout Houston Electric’s certificated service 
territory. Houston Electric constructs and maintains transmission facilities and provides transmission services under tariffs approved 
by the PUCT.

Electric Distribution

In ERCOT, end users purchase their electricity directly from certificated REPs. Houston Electric delivers electricity for REPs 
in its certificated service area by carrying lower-voltage power from the substation to the retail electric customer. Houston Electric’s 
distribution network receives electricity from the transmission grid through power distribution substations and delivers electricity 
to end  users through  distribution feeders.  Houston Electric’s  operations  include construction and  maintenance of  distribution 
facilities, metering services, outage response services and call center operations. Houston Electric provides distribution services 
under tariffs approved by the PUCT. PUCT rules and market protocols govern the commercial operations of distribution companies 
and other market participants. Rates for these existing services are established pursuant to rate proceedings conducted before 
municipalities that have original jurisdiction and the PUCT.

ERCOT Market Framework

Houston  Electric  is  a  member  of  ERCOT.   Within  ERCOT,  prices  for  wholesale  generation  and  retail  electric  sales  are 
unregulated, but services provided by transmission and distribution companies, such as Houston Electric, are regulated by the 
PUCT.  ERCOT serves as the regional reliability coordinating council for member electric power systems in most of Texas. ERCOT 
membership is open to consumer groups, investor and municipally-owned electric utilities, rural electric cooperatives, independent 
generators, power marketers, river authorities and REPs. The ERCOT market includes most of the State of Texas, other than a 
portion of the panhandle, portions of the eastern part of the state bordering Arkansas and Louisiana and the area in and around 
El Paso. The ERCOT market represents approximately 90% of the demand for power in Texas and is one of the nation’s largest 
power markets. The ERCOT market included available generating capacity of over 78,000 megawatts as of December 31, 2016. 
Currently, there are only limited direct current interconnections between the ERCOT market and other power markets in the 
United States and Mexico.

The ERCOT market operates under the reliability standards set by the NERC and approved by the FERC. Within ERCOT, 
these reliability standards are administered by the TRE. The PUCT has primary jurisdiction over the ERCOT market to ensure 
the adequacy and reliability of electricity supply across the state’s main interconnected power transmission grid. The ERCOT ISO 
is responsible for operating the bulk electric power supply system in the ERCOT market. Its responsibilities include ensuring that 
electricity production and delivery are accurately accounted for among the generation resources and wholesale buyers and sellers. 

Houston Electric’s electric transmission business, along with those of other owners of transmission facilities in Texas, supports 
the  operation  of  the  ERCOT  ISO. The  transmission  business  has  planning,  design,  construction,  operation  and  maintenance 
responsibility for the portion of the transmission grid and for the load-serving substations it owns, primarily within its certificated 
area. Houston Electric participates with the ERCOT ISO and other ERCOT utilities to plan, design, obtain regulatory approval 
for and construct new transmission lines necessary to increase bulk power transfer capability and to remove existing constraints 
on the ERCOT transmission grid.

Restructuring of the Texas Electric Market

In 1999, the Texas legislature adopted the Texas Electric Choice Plan (Texas electric restructuring law). Pursuant to that 
legislation, integrated electric utilities operating within ERCOT were required to unbundle their integrated operations into separate 
retail sales, power generation and transmission and distribution companies.  The legislation provided for a transition period to 
move to the new market structure and provided a mechanism for the formerly integrated electric utilities to recover stranded and 
certain other costs resulting from the transition to competition. Those costs were recoverable after approval by the PUCT either 
through the issuance of securitization bonds or through the implementation of a competition transition charge as a rider to the 
utility’s tariff.  Houston Electric’s integrated utility business was restructured in accordance with the Texas electric restructuring 
law  and  its  generating  stations  were  sold  to  third  parties.    Ultimately  Houston  Electric  was  authorized  to  recover  a  total  of 
approximately $5 billion in stranded costs, other charges and related interest.  Most of that amount was recovered through the 
issuance of transition bonds by special purpose subsidiaries of Houston Electric.  The transition bonds are repaid through charges 
imposed on customers in Houston Electric’s service territory.  As of December 31, 2016, approximately $1.9 billion aggregate 
principal amount of transition bonds were outstanding.

Customers

Houston Electric serves nearly all of the Houston/Galveston metropolitan area. At December 31, 2016, Houston Electric’s 
customers consisted of approximately 64 REPs, which sell electricity to more than 2.4 million metered customers in Houston 
Electric’s  certificated  service  area,  and  municipalities,  electric  cooperatives  and  other  distribution  companies  located  outside 
Houston Electric’s certificated service area. Each REP is licensed by, and must meet minimum creditworthiness criteria established 
by, the PUCT.

Sales to REPs that are affiliates of NRG represented approximately 34%, 35% and 37% of Houston Electric’s transmission 
and  distribution  revenues  in  2016,  2015  and  2014,  respectively.  Sales  to  REPs  that  are  affiliates  of  Energy  Future  Holdings 
represented approximately 11%, 10% and 10% of Houston Electric’s transmission and distribution revenues in 2016, 2015 and 
2014,  respectively.  Houston  Electric’s  aggregate  billed  receivables  balance  from  REPs  as  of  December 31,  2016  was  $193 
million.  Approximately 33% and 12% of this amount was owed by affiliates of NRG and Energy Future Holdings, respectively. 
Houston Electric does not have long-term contracts with any of its customers. It operates using a continuous billing cycle, with 
meter readings being conducted and invoices being distributed to REPs each business day.

AMS 

In May 2012, Houston Electric substantially completed the deployment of an AMS, having installed approximately 2.2 million 
smart meters. To recover the cost of the AMS, the PUCT approved a monthly surcharge payable by REPs, initially over 12 years 
and later reduced to six years as a result of DOE grant funds.  The surcharge expired in 2015 and 2016 for residential customers 
and certain non-residential customers, respectively, and is set to expire in 2017 for the remaining non-residential customers.  The 
surcharge amounts and duration are subject to adjustment in future proceedings to reflect actual costs incurred and to address 
required changes in scope.  

Competition

There are no other electric transmission and distribution utilities in Houston Electric’s service area. For another provider of 
transmission and distribution services to provide such services in Houston Electric’s territory, it would be required to obtain a 
certificate of convenience and necessity from the PUCT and, depending on the location of the facilities, may also be required to 
obtain franchises from one or more municipalities. We know of no other party intending to enter this business in Houston Electric’s 
service area at this time. Distributed generation (i.e., power generation located at or near the point of consumption) could result 
in a reduction of demand for Houston Electric’s electric distribution services but has not been a significant factor to date.

Seasonality

A significant portion of Houston Electric’s revenues is derived from rates that it collects from each REP based on the amount 
of electricity it delivers on behalf of that REP. Thus, Houston Electric’s revenues and results of operations are subject to seasonality, 
weather conditions and other changes in electricity usage, with revenues generally being higher during the warmer months.

Properties

All of Houston Electric’s properties are located in Texas. Its properties consist primarily of high-voltage electric transmission 
lines and poles, distribution lines, substations, service centers, service wires and meters. Most of Houston Electric’s transmission 
and distribution lines have been constructed over lands of others pursuant to easements or along public highways and streets under 
franchise agreements and as permitted by law.

All real and tangible properties of Houston Electric, subject to certain exclusions, are currently subject to:

• 

• 

the lien of a Mortgage and Deed of Trust (the Mortgage) dated November 1, 1944, as supplemented; and

the lien of a General Mortgage (the General Mortgage) dated October 10, 2002, as supplemented, which is junior to the 
lien of the Mortgage.

As of December 31, 2016, Houston Electric had approximately $2.6 billion aggregate principal amount of general mortgage 
bonds outstanding under the General Mortgage, including approximately $118 million held in trust to secure pollution control 
bonds  for  which  we  are  obligated. Additionally,  as  of  December 31,  2016,  Houston  Electric  had  approximately  $102 million 
aggregate principal amount of first mortgage bonds outstanding under the Mortgage. Houston Electric may issue additional general 
3

mortgage  bonds  on  the  basis  of  retired  bonds,  70%  of  property  additions  or  cash  deposited  with  the  trustee. Approximately 
$4.1 billion of additional first mortgage bonds and general mortgage bonds in the aggregate could be issued on the basis of retired 
bonds and 70% of property additions as of December 31, 2016. However, Houston Electric has contractually agreed that it will 
not issue additional first mortgage bonds, subject to certain exceptions.

Electric Lines - Overhead.  As of December 31, 2016, Houston Electric owned 28,702 pole miles of overhead distribution 
lines and 3,692 circuit miles of overhead transmission lines, including 287 circuit miles operated at 69,000 volts, 2,188 circuit 
miles operated at 138,000 volts and 1,217 circuit miles operated at 345,000 volts.

Electric  Lines -  Underground.  As  of  December 31,  2016,  Houston  Electric  owned  23,937  circuit  miles  of  underground 
distribution lines and 26 circuit miles of underground transmission lines, including two circuit miles operated at 69,000 volts and 
24 circuit miles operated at 138,000 volts.

Substations.  As of December 31, 2016, Houston Electric owned 232 major substation sites having a total installed rated 

transformer capacity of 60,854 megavolt amperes.

Service Centers.  Houston Electric operates 14 regional service centers located on a total of 292 acres of land. These service 
centers consist of office buildings, warehouses and repair facilities that are used in the business of transmitting and distributing 
electricity.

Franchises

Houston Electric holds non-exclusive franchises from certain incorporated municipalities in its service territory. In exchange 
for  the  payment  of  fees,  these  franchises  give  Houston  Electric  the  right  to  use  the  streets  and  public  rights-of-way  of  these 
municipalities to construct, operate and maintain its transmission and distribution system and to use that system to conduct its 
electric delivery business and for other purposes that the franchises permit. The terms of the franchises, with various expiration 
dates, typically range from 20 to 40 years.

Natural Gas Distribution

CERC  Corp.’s  NGD  engages  in  regulated  intrastate  natural  gas  sales  to,  and  natural  gas  transportation  and  storage  for, 
approximately 3.4 million residential, commercial, industrial and transportation customers in Arkansas, Louisiana, Minnesota, 
Mississippi, Oklahoma and Texas. The largest metropolitan areas served in each state by NGD are Houston, Texas; Minneapolis, 
Minnesota; Little Rock, Arkansas; Shreveport, Louisiana; Biloxi, Mississippi; and Lawton, Oklahoma. In 2016, approximately 
37%  of  NGD’s  total  throughput  was  to  residential  customers  and  approximately  63%  was  to  commercial  and  industrial  and 
transportation customers.

The table below reflects the number of NGD customers by state as of December 31, 2016:

NGD also provides unregulated services in Minnesota consisting of residential appliance repair and maintenance services 

along with HVAC equipment sales.

Seasonality

The demand for intrastate natural gas sales to residential customers and natural gas sales and transportation for commercial 
and industrial customers is seasonal. In 2016, approximately 66% of NGD’s total throughput occurred in the first and fourth 
quarters. These patterns reflect the higher demand for natural gas for heating purposes during the colder months.

4

Supply and Transportation.  In 2016, NGD purchased virtually all of its natural gas supply pursuant to contracts with remaining 

terms varying from a few months to four years. Major suppliers in 2016 included the following:

 Numerous other suppliers provided the remaining 23.4% of NGD’s natural gas supply requirements. NGD transports its 
natural gas supplies through various intrastate and interstate pipelines under contracts with remaining terms, including extensions, 
varying from one to fifteen years. NGD anticipates that these gas supply and transportation contracts will be renewed or replaced 
prior to their expiration.

NGD actively engages in commodity price stabilization pursuant to annual gas supply plans presented to and/or filed with 
each of its state regulatory authorities. These price stabilization activities include use of storage gas and contractually establishing 
structured prices (e.g., fixed price, costless collars and caps) with our physical gas suppliers. Its gas supply plans generally call 
for 50–75% of winter supplies to be stabilized in some fashion.

The regulations of the states in which NGD operates allow it to pass through changes in the cost of natural gas, including 
savings and costs of financial derivatives associated with the index-priced physical supply, to its customers under purchased gas 
adjustment provisions in its tariffs. Depending upon the jurisdiction, the purchased gas adjustment factors are updated periodically, 
ranging from monthly to semi-annually. The changes in the cost of gas billed to customers are subject to review by the applicable 
regulatory bodies.

NGD uses various third-party storage services or owned natural gas storage facilities to meet peak-day requirements and to 
manage the daily changes in demand due to changes in weather.  NGD may also supplement contracted supplies and storage from 
time to time with stored LNG and propane-air plant production.

NGD owns and operates an underground natural gas storage facility with a capacity of 7.0 Bcf. It has a working capacity of 
2.0 Bcf available for use during the heating season and a maximum daily withdrawal rate of 50 MMcf. It also owns eight propane-
air plants with a total production rate of 180,000 Dth per day and on-site storage facilities for 12 million gallons of propane (1.0 Bcf 
natural gas equivalent). It owns a LNG plant facility with a 12 million-gallon LNG storage tank (1.0 Bcf natural gas equivalent) 
and a production rate of 72,000 Dth per day. 

On an ongoing basis, NGD enters into contracts to provide sufficient supplies and pipeline capacity to meet its customer 
requirements.  However,  it  is  possible  for  limited  service  disruptions  to  occur  from  time  to  time  due  to  weather  conditions, 
transportation constraints and other events. As a result of these factors, supplies of natural gas may become unavailable from time 
to time, or prices may increase rapidly in response to temporary supply constraints or other factors.

NGD has had AMAs associated with its utility distribution service in Arkansas, Louisiana, Mississippi, Oklahoma and Texas.  
Generally, AMAs are contracts between NGD and an asset manager that are intended to transfer the working capital obligation 
and maximize the utilization of the assets. In these agreements, NGD agrees to release transportation and storage capacity to other 
parties to manage natural gas storage, supply and delivery arrangements for NGD and to use the released capacity for other purposes 
when it is not needed for NGD. NGD is compensated by the asset manager through payments made over the life of the agreements 
based in part on the results of the asset optimization.  NGD has an obligation to purchase its winter storage requirements that have 
been released to the asset manager under these AMAs. NGD has received approval from the state regulatory commissions in 
Arkansas, Louisiana, Mississippi and Oklahoma to retain a share of the AMA proceeds. NGD currently has AMAs in Arkansas, 
north Louisiana and Oklahoma that extend through 2020.

5

Assets

As of December 31, 2016, NGD owned approximately 74,000 linear miles of natural gas distribution mains, varying in size 
from one-half inch to 24 inches in diameter. Generally, in each of the cities, towns and rural areas served by NGD, it owns the 
underground gas mains and service lines, metering and regulating equipment located on customers’ premises and the district 
regulating equipment necessary for pressure maintenance. With a few exceptions, the measuring stations at which NGD receives 
gas are owned, operated and maintained by others, and its distribution facilities begin at the outlet of the measuring equipment. 
These facilities, including odorizing equipment, are usually located on land owned by suppliers. 

Competition

NGD competes primarily with alternate energy sources such as electricity and other fuel sources. In some areas, intrastate 
pipelines, other gas distributors and marketers also compete directly for gas sales to end users. In addition, as a result of federal 
regulations affecting interstate pipelines, natural gas marketers operating on these pipelines may be able to bypass NGD’s facilities 
and market and sell and/or transport natural gas directly to commercial and industrial customers.

Energy Services

CERC  offers  competitive  variable  and  fixed-priced  physical  natural  gas  supplies  primarily  to  commercial  and  industrial 

customers and electric and natural gas utilities through CES and its subsidiary, CEIP.

In 2016, CES marketed approximately 777 Bcf of natural gas, related energy services and transportation to approximately 
31,000 customers (including approximately 8 Bcf to affiliates) in 31 states.  These totals include approximately 13,000 customers 
and 175 Bcf of natural gas related to the acquisition of Continuum, which closed in April 2016, and was fully integrated into CES 
by the end of 2016.  CES customers vary in size from small commercial customers to large utility companies.  Not included in 
the 2016 customer count are approximately 60,000 natural gas customers that are served under residential and small commercial 
choice programs invoiced by their host utility.  These customers are not included in customer count so as not to distort the significant 
margin impact from the remaining customer base.

In January 2017, CES completed the acquisition of AEM.  For information related to this acquisition, see Note 19 to our 

consolidated financial statements.  

CES offers a variety of natural gas management services to gas utilities, large industrial customers, electric generators, smaller 
commercial and industrial customers, municipalities, educational institutions and hospitals. These services include load forecasting, 
supply acquisition, daily swing volume management, invoice consolidation, storage asset management, firm and interruptible 
transportation administration and forward price management. CES also offers a portfolio of physical delivery services designed 
to meet customers’ supply and price risk management needs. These customers are served directly, through interconnects with 
various interstate and intrastate pipeline companies, and portably, through our mobile energy solutions business.

In addition to offering natural gas management services, CES procures and optimizes transportation and storage assets. CES 
maintains  a  portfolio  of  natural  gas  supply  contracts  and  firm  transportation  and  storage  agreements  to  meet  the  natural  gas 
requirements of its customers. CES aggregates supply from various producing regions and offers contracts to buy natural gas with 
terms ranging from one month to over five years. In addition, CES actively participates in the spot natural gas markets in an effort 
to balance daily and monthly purchases and sales obligations. Natural gas supply and transportation capabilities are leveraged 
through contracts for ancillary services including physical storage and other balancing arrangements.

As described above, CES offers its customers a variety of load following services. In providing these services, CES uses its 
customers’ purchase commitments to forecast and arrange its own supply purchases, storage and transportation services to serve 
customers’ natural gas requirements. As a result of the variance between this forecast activity and the actual monthly activity, CES 
will either have too much supply or too little supply relative to its customers’ purchase commitments. These supply imbalances 
arise each month as customers’ natural gas requirements are scheduled and corresponding natural gas supplies are nominated by 
CES for delivery to those customers. CES’ processes and risk control environment are designed to measure and value imbalances 
on a real-time basis to ensure that CES’ exposure to commodity price risk is kept to a minimum. The value assigned to these 
imbalances is calculated daily and is known as the aggregate VaR.

Our  risk  control  policy,  which  is  overseen  by  our  Risk  Oversight  Committee,  defines  authorized  and  prohibited  trading 
instruments and trading limits. CES is a physical marketer of natural gas and uses a variety of tools, including pipeline and storage 
capacity, financial instruments and physical commodity purchase contracts, to support its sales. CES optimizes its use of these 

6

various tools to minimize its supply costs and does not engage in speculative commodity trading.  The VaR limit within which 
CES currently operates, a $4 million maximum set by the board of directors, is consistent with CES’ operational objective of 
matching its aggregate sales obligations (including the swing associated with load following services) with its supply portfolio in 
a manner that minimizes its total cost of supply. In 2016, CES’ VaR averaged $0.2 million with a high of $1.0 million.

Assets 

CEIP owns and operates over 200 miles of intrastate pipeline in Louisiana and Texas. In addition, CES leases transportation 

capacity on various interstate and intrastate pipelines and storage to service its shippers and end users.

Competition

CES competes with regional and national wholesale and retail gas marketers, including the marketing divisions of natural gas 

producers and utilities. In addition, CES competes with intrastate pipelines for customers and services in its market areas.

Midstream Investments

Our Midstream Investments business segment consists of CERC Corp.’s equity method investment in Enable. Enable is a 

publicly traded MLP, jointly controlled by CERC Corp. and OGE.  

Enable.  Enable was formed to own, operate and develop strategically located natural gas and crude oil infrastructure assets.   

Enable serves current and emerging production areas in the United States, including several unconventional shale resource plays 
and local and regional end-user markets in the United States. Enable’s assets and operations are organized into two reportable 
segments: (i) gathering and processing, which primarily provides natural gas gathering, processing and fractionation services and 
crude oil gathering for its producer customers, and (ii) transportation and storage, which provides interstate and intrastate natural 
gas pipeline transportation and storage services primarily to natural gas producers, utilities and industrial customers.

Enable’s natural gas gathering and processing assets are located in Oklahoma,Texas, Arkansas, Louisiana and Mississippi 
and serve natural gas production in the Anadarko, Arkoma and Ark-La-Tex basins. Enable also owns a crude oil gathering business 
located in North Dakota that commenced initial operations in November 2013 to serve shale development in the Bakken Shale 
formation of the Williston Basin. Enable’s natural gas transportation and storage assets extend from western Oklahoma and the 
Texas Panhandle to Alabama and from Louisiana to Illinois.

Enable’s Gathering and Processing segment. Enable provides gathering, compression, treating, dehydration, processing and 
NGLs fractionation for producers who are active in the areas in which Enable operates. Enable’s super-header system is intended 
to optimize the economics of its natural gas processing and to improve system utilization and reliability.

Enable’s gathering and processing systems compete with gatherers and processors of all types and sizes, including those 
affiliated with various producers, other major pipeline companies and various independent midstream entities. In the process of 
selling NGLs, Enable competes against other natural gas processors extracting and selling NGLs. Enable’s primary competitors 
are master limited partnerships who are active in the regions where it operates. 

Enable’s Transportation and Storage segment. Enable provides fee-based interstate and intrastate transportation and storage 
services across nine states.  Enable’s transportation and storage assets were designed and built to serve large natural gas and electric 
utility companies in its areas of operation. 

Enable’s interstate pipelines compete with other interstate and intrastate pipelines. Enable’s intrastate pipeline system competes 
with numerous interstate and intrastate pipelines, including several of the interconnected pipelines discussed above, as well as 
other natural gas storage facilities. The principal elements of competition among pipelines are rates, terms of service, and flexibility 
and reliability of service.

For information related to CERC Corp.’s equity method investment in Enable, see Notes 2(b), 10 and 19 to our consolidated 

financial statements.

Other Operations

Our Other Operations business segment includes office buildings and other real estate used in our business operations and 

other corporate operations that support all of our business operations.

Financial Information About Segments

For financial information about our segments, see Note 18 to our consolidated financial statements, which note is incorporated 

herein by reference.

We are subject to regulation by various federal, state and local governmental agencies, including the regulations described 

REGULATION

below.

Federal Energy Regulatory Commission

The FERC has jurisdiction under the NGA and the NGPA, as amended, to regulate the transportation of natural gas in interstate 
commerce and natural gas sales for resale in interstate commerce that are not first sales. The FERC regulates, among other things, 
the construction of pipeline and related facilities used in the transportation and storage of natural gas in interstate commerce, 
including the extension, expansion or abandonment of these facilities. The FERC has authority to prohibit market manipulation 
in connection with FERC-regulated transactions and to impose significant civil and criminal penalties for statutory violations and 
violations of the FERC’s rules or orders. Our Energy Services business segment markets natural gas in interstate commerce pursuant 
to blanket authority granted by the FERC.

Houston Electric is not a “public utility” under the Federal Power Act and, therefore, is not generally regulated by the FERC, 
although certain of its transactions are subject to limited FERC jurisdiction. The FERC has certain responsibilities with respect 
to ensuring the reliability of electric transmission service, including transmission facilities owned by Houston Electric and other 
utilities within ERCOT. The FERC has designated the NERC as the ERO to promulgate standards, under FERC oversight, for all 
owners, operators and users of the bulk power system (Electric Entities). The ERO and the FERC have authority to (a) impose 
fines and other sanctions on Electric Entities that fail to comply with approved standards and (b) audit compliance with approved 
standards. The FERC has approved the delegation by the NERC of authority for reliability in ERCOT to the TRE. Houston Electric 
does not anticipate that the reliability standards proposed by the NERC and approved by the FERC will have a material adverse 
impact on its operations. To the extent that Houston Electric is required to make additional expenditures to comply with these 
standards, it is anticipated that Houston Electric will seek to recover those costs through the transmission charges that are imposed 
on all distribution service providers within ERCOT for electric transmission provided.

As  a  public  utility  holding  company,  under  the  Public  Utility  Holding  Company Act  of  2005,  we  and  our  consolidated 
subsidiaries are subject to reporting and accounting requirements and are required to maintain certain books and records and make 
them available for review by the FERC and state regulatory authorities in certain circumstances.

State and Local Regulation – Electric Transmission & Distribution

Houston Electric conducts its operations pursuant to a certificate of convenience and necessity issued by the PUCT that covers 
its present service area and facilities. The PUCT and certain municipalities have the authority to set the rates and terms of service 
provided by Houston Electric under cost-of-service rate regulation. Houston Electric holds non-exclusive franchises from certain 
incorporated municipalities in its service territory. In exchange for payment of fees, these franchises give Houston Electric the 
right to use the streets and public rights-of-way of these municipalities to construct, operate and maintain its transmission and 
distribution system and to use that system to conduct its electric delivery business and for other purposes that the franchises permit. 
The terms of the franchises, with various expiration dates, typically range from 20 to 40 years.

Houston Electric’s distribution rates charged to REPs for residential customers are primarily based on amounts of energy 
delivered, whereas distribution rates for a majority of commercial and industrial customers are primarily based on peak demand. 
All REPs in Houston Electric’s service area pay the same rates and other charges for transmission and distribution services. This 
regulated delivery charge includes the transmission and distribution rate (which includes municipal franchise fees), a distribution 
recovery mechanism for recovery of incremental distribution-invested capital above that which is already reflected in the base 
distribution rate, a nuclear decommissioning charge associated with decommissioning the South Texas nuclear generating facility, 
an EECR charge, a surcharge related to the implementation of AMS and charges associated with securitization of regulatory assets, 
stranded costs and restoration costs relating to Hurricane Ike. Transmission rates charged to distribution companies are based on 
amounts of energy transmitted under “postage stamp” rates that do not vary with the distance the energy is being transmitted. All 
distribution companies in ERCOT pay Houston Electric the same rates and other charges for transmission services.

State and Local Regulation – Natural Gas Distribution

In almost all communities in which NGD provides natural gas distribution services, it operates under franchises, certificates 
or licenses obtained from state and local authorities. The original terms of the franchises, with various expiration dates, typically 
range from 10 to 30 years, although franchises in Arkansas are perpetual. NGD expects to be able to renew expiring franchises. 
In most cases, franchises to provide natural gas utility services are not exclusive.

Substantially all of NGD is subject to cost-of-service rate regulation by the relevant state public utility commissions and, in 
Texas, by the Railroad Commission and those municipalities served by NGD that have retained original jurisdiction.  In certain 
of its jurisdictions, NGD has in effect annual rate adjustment mechanisms that provide for changes in rates dependent upon certain 
changes in invested capital, earned returns on equity or actual margins realized.

Condition and Results of Operations — Liquidity and Capital Resources — Regulatory Matters” in Item 7 of Part II of this report, 
which discussion is incorporated herein by reference.

Department of Transportation

In December 2006, Congress enacted the 2006 Act, which reauthorized the programs adopted under the 2002 Act.  These 
programs included several requirements related to ensuring pipeline safety, and a requirement to assess the integrity of pipeline 
transmission facilities in areas of high population concentration. 

Pursuant to the 2006 Act, PHMSA at the DOT issued regulations, effective February 12, 2010, requiring operators of gas 
distribution pipelines to develop and implement integrity management programs similar to those required for gas transmission 
pipelines, but tailored to reflect the differences in distribution pipelines. Operators of natural gas distribution systems were required 
to write and implement their integrity management programs by August 2, 2011.  Our natural gas distribution systems met this 
deadline.

Pursuant  to  the  2002 Act  and  the  2006 Act,  PHMSA  has  adopted  a  number  of  rules  concerning,  among  other  things, 
distinguishing between gathering lines and transmission facilities, requiring certain design and construction features in new and 
replaced lines to reduce corrosion and requiring pipeline operators to amend existing written operations and maintenance procedures 
and operator qualification programs.  PHMSA also updated its reporting requirements for natural gas pipelines effective January 
1, 2011. 

In  December  2011,  Congress  passed  the  2011 Act.  This  act  increases  the  maximum  civil  penalties  for  pipeline  safety 
administrative enforcement actions; requires the DOT to study and report on the expansion of integrity management requirements 
and the sufficiency of existing gathering line regulations to ensure safety; requires pipeline operators to verify their records on 
maximum allowable operating pressure; and imposes new emergency response and incident notification requirements. In 2016, 
the 2016 Act reauthorized PHMSA’s pipeline safety programs through 2019 and provided limited new authority, including the 
ability to issue emergency orders, to set inspection requirements for certain underwater pipelines and to promulgate minimum 
safety standards for natural gas storage facilities, as well as to provide increased transparency into the status of as-yet-incomplete 
PHMSA actions required by the 2011 Act.

We anticipate that compliance with PHMSA’s regulations, performance of the remediation activities by CERC’s natural gas 
distribution companies and intrastate pipelines and verification of records on maximum allowable operating pressure will continue 
to require increases in both capital expenditures and operating costs. The level of expenditures will depend upon several factors, 
including age, location and operating pressures of the facilities. In particular, the cost of compliance with the DOT’s integrity 
management rules will depend on integrity testing and the repairs found to be necessary by such testing. Changes to the amount 
of pipe subject to integrity management, whether by expansion of the definition of the type of areas subject to integrity management 
procedures  or  of  the  applicability  of  such  procedures  outside  of  those  defined  areas,  may  also  affect  the  costs  we  incur. 
Implementation of the 2011 and 2016 Acts by PHMSA may result in other regulations or the reinterpretation of existing regulations 
that could impact our compliance costs. In addition, we may be subject to the DOT’s enforcement actions and penalties if we fail 
to comply with pipeline regulations.

Midstream Investments – Rate and Other Regulation 

Federal, state, and local regulation may affect certain aspects of Enable’s business.

Interstate Natural Gas Pipeline Regulation

Enable’s interstate pipeline systems—EGT, MRT and SESH—are subject to regulation by the FERC under the NGA and are 
considered natural gas companies. Under the NGA, the rates for service on Enable’s interstate facilities must be just and reasonable 
and not unduly discriminatory. Tariff changes for these facilities can only be implemented upon approval by the FERC. Enable’s 
interstate pipelines business operations may be affected by changes in the demand for natural gas, the available supply and relative 
price of natural gas in the Mid-continent and Gulf Coast natural gas supply regions and general economic conditions. 

Market Behavior Rules; Posting and Reporting Requirements

The EPAct of 2005 amended the NGA to add an anti-manipulation provision that makes it unlawful for any entity to engage 
in prohibited behavior as prescribed in FERC rules, which were subsequently issued in FERC Order No. 670. The EPAct of 2005 
also amends the NGA and the NGPA to give the FERC authority to impose civil penalties for violations of these statutes and 
FERC’s regulations, rules, and orders, of up to $1 million per day per violation, subject to periodic adjustment to account for 
inflation. Should Enable fail to comply with all applicable FERC-administered statutes, rules, regulations and orders, it could be 
subject to substantial penalties and fines. In addition, the CFTC is directed under the CEA to prevent price manipulations for the 
commodity and futures markets, including the energy futures markets. Pursuant to the Dodd-Frank Act and other authority, the 
CFTC has adopted anti-market manipulation regulations that prohibit fraud and price manipulation in the commodity and futures 
markets. The CFTC also has statutory authority to seek civil penalties of up to the greater of $1 million or triple the monetary gain 
to the violator for violations of the anti-market manipulation sections of the CEA. These maximum penalty levels are also subject 
to periodic adjustment to account for inflation.

Intrastate Natural Gas Pipeline and Storage Regulation

Intrastate natural gas transportation is largely regulated by the state in which the transportation takes place. However, an 
intrastate natural gas pipeline system may transport natural gas in interstate commerce provided that the rates, terms, and conditions 
of such transportation service comply with FERC regulation and Section 311 of the NGPA and Part 284 of the FERC’s regulations. 
Rates for service pursuant to Section 311 of the NGPA are generally subject to review and approval by the FERC at least once 
every five years. Failure to observe the service limitations applicable to transportation services provided under Section 311, failure 
to comply with the rates approved by the FERC for Section 311 service, or failure to comply with the terms and conditions of 
service established in the pipeline’s FERC-approved Statement of Operating Conditions could result in the assertion of federal 
NGA jurisdiction by the FERC and/or the imposition of administrative, civil and criminal penalties, as described under  “—
Interstate Natural Gas Pipeline Regulation” above.

Natural Gas Gathering Pipeline Regulation

Section 1(b) of the NGA exempts natural gas gathering facilities from the jurisdiction of the FERC. Although the FERC has 
not made formal determinations with respect to all of the facilities Enable considers to be gathering facilities, Enable believes that 
its natural gas pipelines meet the traditional tests that the FERC has used to determine that a pipeline is a gathering pipeline and 
is therefore not subject to FERC jurisdiction. The distinction, however, has been the subject of substantial litigation, and the FERC 
determines  whether  facilities  are  gathering  facilities  on  a  case-by-case  basis,  so  the  classification  and  regulation  of  Enable’s 
gathering facilities is subject to change based on future determinations. 

States  may  regulate  gathering  pipelines.  State  regulation  generally  includes  various  safety,  environmental  and,  in  some 
circumstances,  anti-discrimination  requirements,  and  in  some  instances  complaint-based  rate  regulation.  Enable’s  gathering 
operations may be subject to ratable take and common purchaser statutes in the states in which they operate.

Enable’s gathering operations could be adversely affected should they be subject in the future to the application of state or 
federal regulation of rates and services. Enable’s gathering operations could also be subject to additional safety and operational 
regulations relating to the design, construction, testing, operation, replacement and maintenance of gathering facilities. We cannot 
predict what effect, if any, such changes might have on Enable’s operations, but the industry could be required to incur additional 
capital expenditures and increased costs depending on future legislative and regulatory changes.

10

Crude Oil Gathering Regulation

Enable provides interstate transportation on its crude oil gathering system in North Dakota pursuant to a public tariff in 
accordance with FERC regulatory requirements.  Crude oil gathering pipelines that provide interstate transportation service may 
be regulated as a common carrier by the FERC under the ICA, the Energy Policy Act of 1992, and the rules and regulations 
promulgated under those laws. The ICA and FERC regulations require that rates for interstate service pipelines that transport crude 
oil and refined petroleum products (collectively referred to as “petroleum pipelines”) and certain other liquids, be just and reasonable 
and non-discriminatory or not conferring any undue preference upon any shipper. FERC regulations also require interstate common 
carrier petroleum pipelines to file with the FERC and publicly post tariffs stating their interstate transportation rates and terms 
and conditions of service.

Safety and Health Regulation

Certain of Enable’s facilities are subject to pipeline safety regulations. PHMSA regulates safety requirements in the design, 
construction,  operation  and  maintenance  of  jurisdictional  natural  gas  and  hazardous  liquid  pipeline  facilities. All  natural  gas 
transmission  facilities,  such  as  Enable’s  interstate  natural  gas  pipelines,  are  subject  to  PHMSA’s  regulations,  but  natural  gas 
gathering pipelines are subject only to the extent they are classified as regulated gathering pipelines. In addition, several NGL 
pipeline facilities and crude oil pipeline facilities are regulated as hazardous liquids pipelines. 

Pursuant to various federal statutes, including the NGPSA, the DOT, through PHMSA, regulates pipeline safety and integrity. 
NGL and crude oil pipelines are subject to regulation by PHMSA under the Hazardous Liquid Pipeline Safety Act which requires 
PHMSA to develop, prescribe, and enforce minimum federal safety standards for the transportation of hazardous liquids by pipeline, 
and comparable state statutes with respect to design, installation, testing, construction, operation, replacement and management 
of pipeline facilities. Should Enable fail to comply with DOT or comparable state regulations, it could be subject to penalties and 
fines.  If  future  DOT  pipeline  regulations  were  to  require  that  Enable  expand  its  integrity  management  program  to  currently 
unregulated pipelines, costs associated with compliance may have a material effect on its operations.

ENVIRONMENTAL MATTERS

Our operations and the operations of Enable are subject to stringent and complex laws and regulations pertaining to the 
environment. As  an  owner  or  operator  of  natural  gas  pipelines,  distribution  systems  and  storage,  electric  transmission  and 
distribution systems, and the facilities that support these systems, we must comply with these laws and regulations at the federal, 
state and local levels. These laws and regulations can restrict or impact our business activities in many ways, such as:

• 

• 

• 

• 

• 

restricting the way we can handle or dispose of wastes;

limiting or prohibiting construction activities in sensitive areas such as wetlands, coastal regions or areas inhabited by 
endangered species;

requiring  remedial  action  to  mitigate  environmental  conditions  caused  by  our  operations  or  attributable  to  former 
operations;

enjoining the operations of facilities with permits issued pursuant to such environmental laws and regulations; and

impacting the demand for our services by directly or indirectly affecting the use or price of natural gas.

To comply with these requirements, we may need to spend substantial amounts and devote other resources from time to time 

to, among other activities:

• 

• 

construct or acquire new facilities and equipment;

acquire permits for facility operations;

•  modify, upgrade or replace existing and proposed equipment; and

• 

clean or decommission waste management areas, fuel storage facilities and other locations.

Failure to comply with these laws and regulations may trigger a variety of administrative, civil and criminal enforcement 
measures, including the assessment of monetary penalties, the imposition of remedial actions and the issuance of orders enjoining 
11

future operations. Certain environmental statutes impose strict, joint and several liability for costs required to clean up and restore 
sites where hazardous substances have been stored, disposed or released. Moreover, it is not uncommon for neighboring landowners 
and other third parties to file claims for personal injury and property damage allegedly caused by the release of hazardous substances 
or other waste products into the environment.

The recent trend in environmental regulation has been to place more restrictions and limitations on activities that may impact 
the environment.  For example, the EPA has established air emission control requirements for natural gas and NGL production, 
processing and transportation activities, which may affect Enable’s midstream operations. These include New Source Performance 
Standards to address emissions of sulfur dioxide and volatile organic compounds, and the NESHAPS to address hazardous air 
pollutants frequently associated with natural gas production and processing activities. There can be no assurance as to the amount 
or timing of future expenditures for environmental compliance or remediation, and actual future expenditures may be different 
from the amounts we currently anticipate. We try to anticipate future regulatory requirements that might be imposed and plan 
accordingly to maintain compliance with changing environmental laws and regulations and to ensure the costs of such compliance 
are reasonable. 

Based on current regulatory requirements and interpretations, we do not believe that compliance with federal, state or local 
environmental laws and regulations will have a material adverse effect on our business, financial position, results of operations 
or cash flows. In addition, we believe that our current environmental remediation activities will not materially interrupt or diminish 
our operational ability. We cannot assure you that future events, such as changes in existing laws, the promulgation of new laws, 
or the development or discovery of new facts or conditions will not cause us to incur significant costs. The following is a discussion 
of material current environmental and safety laws and regulations that relate to our operations. We believe that we are in substantial 
compliance with these environmental laws and regulations.

Global Climate Change

There is increasing attention being paid in the United States and worldwide to the issue of climate change. As a result, from 
time to time, regulatory agencies have considered the modification of existing laws or regulations or the adoption of new laws or 
regulations addressing the emissions of GHG on the state, federal, or international level. Some of the proposals would require 
industrial sources to meet stringent new standards that would require substantial reductions in GHG emissions. CERC’s revenues, 
operating  costs  and  capital  requirements  could  be  adversely  affected  as  a  result  of  any  regulatory  action  that  would  require 
installation of new control technologies or a modification of its operations or would have the effect of reducing the consumption 
of natural gas. Our electric transmission and distribution business, in contrast to some electric utilities, does not generate electricity 
and thus is not directly exposed to the risk of high capital costs and regulatory uncertainties that face electric utilities that burn 
fossil fuels to generate electricity.  Nevertheless, Houston Electric’s revenues could be adversely affected to the extent any resulting 
regulatory action has the effect of reducing consumption of electricity by ultimate consumers within its service territory. Likewise, 
incentives  to  conserve  energy  or  use  energy  sources  other  than  natural  gas  could  result  in  a  decrease  in  demand  for  our 
services.  Conversely, regulatory actions that effectively promote the consumption of natural gas because of its lower emissions 
characteristics would be expected to beneficially affect CERC and its natural gas-related businesses.  At this point in time, however, 
it would be speculative to try to quantify the magnitude of the impacts from possible new regulatory actions related to GHG 
emissions, either positive or negative, on our businesses.

To the extent climate changes occur, our businesses may be adversely impacted, though we believe any such impacts are 
likely to occur very gradually and hence would be difficult to quantify.  To the extent global climate change results in warmer 
temperatures in our service territories, financial results from our natural gas distribution business could be adversely affected 
through lower gas sales. On the other hand, warmer temperatures in our electric service territory may increase our revenues from 
transmission and distribution through increased demand for electricity for cooling.  Another possible result of climate change is 
more frequent and more severe weather events, such as hurricanes or tornadoes.  Since many of our facilities are located along or 
near the Gulf Coast, increased or more severe hurricanes or tornadoes could increase our costs to repair damaged facilities and 
restore service to our customers. When we cannot deliver electricity or natural gas to customers, or our customers cannot receive 
our services, our financial results can be impacted by lost revenues, and we generally must seek approval from regulators to recover 
restoration costs.  To the extent we are unable to recover those costs, or if higher rates resulting from our recovery of such costs 
result in reduced demand for our services, our future financial results may be adversely impacted.

Air Emissions

Our operations are subject to the federal Clean Air Act and comparable state laws and regulations. These laws and regulations 
regulate emissions of air pollutants from various industrial sources, including processing plants and compressor stations, and also 
impose various monitoring and reporting requirements. Such laws and regulations may require pre-approval for the construction 
or modification of certain projects or facilities expected to produce air emissions or result in the increase of existing air emissions.  
12

We may be required to obtain and strictly comply with air permits containing various emissions and operational limitations, or 
utilize specific emission control technologies to limit emissions. Failure to comply with these requirements could result in monetary 
penalties, injunctions, conditions or restrictions on operations, and potentially criminal enforcement actions. We may be required 
to incur certain capital expenditures in the future for air pollution control equipment in connection with obtaining and maintaining 
operating permits and approvals for air emissions.

The  EPA  has  established  new  air  emission  control  requirements  for  natural  gas  and  NGLs  production,  processing  and 
transportation activities. Under the NESHAPS, the EPA established maximum achievable control technology for stationary internal 
combustion engines (sometimes referred to as the RICE MACT rule). Compressors and back up electrical generators used by our 
Natural Gas Distribution business segment, and back up electrical generators used by our Electric Transmission & Distribution 
business segment, are substantially compliant with these laws and regulations.

Water Discharges

Our operations are subject to the Federal Water Pollution Control Act of 1972, as amended, also known as the Clean Water 
Act, and analogous state laws and regulations. These laws and regulations impose detailed requirements and strict controls regarding 
the discharge of pollutants into waters of the United States. The unpermitted discharge of pollutants, including discharges resulting 
from a spill or leak incident, is prohibited. The Clean Water Act and regulations implemented thereunder also prohibit discharges 
of dredged and fill material in wetlands and other waters of the United States unless authorized by an appropriately issued permit. 
Any unpermitted release of petroleum or other pollutants from our pipelines or facilities could result in fines or penalties as well 
as significant remedial obligations.

Hazardous Waste

Our operations generate wastes, including some hazardous wastes, that are subject to the federal RCRA, and comparable state 
laws, which impose detailed requirements for the handling, storage, treatment, transport and disposal of hazardous and solid waste. 
RCRA  currently  exempts  many  natural  gas  gathering  and  field  processing  wastes  from  classification  as  hazardous  waste. 
Specifically,  RCRA  excludes  from  the  definition  of  hazardous  waste  waters  produced  and  other  wastes  associated  with  the 
exploration, development or production of crude oil and natural gas. However, these oil and gas exploration and production wastes 
are still regulated under state law and the less stringent non-hazardous waste requirements of RCRA. Moreover, ordinary industrial 
wastes such as paint wastes, waste solvents, laboratory wastes and waste compressor oils may be regulated as hazardous waste. 
The  transportation  of  natural  gas  in  pipelines  may  also  generate  some  hazardous  wastes  that  would  be  subject  to  RCRA  or 
comparable state law requirements.

Liability for Remediation

CERCLA, also known as “Superfund,” and comparable state laws impose liability, without regard to fault or the legality of 
the original conduct, on certain classes of persons responsible for the release of hazardous substances into the environment. Such 
classes of persons include the current and past owners or operators of sites where a hazardous substance was released and companies 
that disposed or arranged for the disposal of hazardous substances at offsite locations such as landfills. Although petroleum, as 
well as natural gas, is excluded from CERCLA’s definition of a “hazardous substance,” in the course of our ordinary operations 
we generate wastes that may fall within the definition of a “hazardous substance.” CERCLA authorizes the EPA and, in some 
cases, third parties to take action in response to threats to the public health or the environment and to seek to recover from the 
responsible classes of persons the costs they incur. Under CERCLA, we could be subject to joint and several liability for the costs 
of cleaning up and restoring sites where hazardous substances have been released, for damages to natural resources, and for the 
costs of certain health studies.

Liability for Preexisting Conditions

Item 1A. 

Risk Factors  

We are a holding company that conducts all of our business operations through subsidiaries, primarily Houston Electric and 
CERC. We also own interests in Enable. The following, along with any additional legal proceedings identified or incorporated by 
reference in Item 3 of this report, summarizes the principal risk factors associated with the businesses conducted by our subsidiaries 
and our interests in Enable:

Risk Factors Associated with Our Consolidated Financial Condition

As a holding company with no operations of our own, we will depend on distributions from our subsidiaries and from Enable 
to meet our payment obligations and to pay dividends on our common stock, and provisions of applicable law or contractual 
restrictions could limit the amount of those distributions.

We derive all of our operating income from, and hold all of our assets through, our subsidiaries, including our interests in 
Enable. As a result, we depend on distributions from our subsidiaries and Enable to meet our payment obligations and to pay 
dividends on our common stock. In general, our subsidiaries are separate and distinct legal entities and have no obligation to 
provide us with funds for our payment obligations, whether by dividends, distributions, loans or otherwise. In addition, provisions 
of applicable law, such as those limiting the legal sources of dividends, limit our subsidiaries’ ability to make payments or other 
distributions to us, and our subsidiaries could agree to contractual restrictions on their ability to make distributions.  For a discussion 
15

of risks that may impact the amount of cash distributions we receive with respect to our interests in Enable, please read “ — 
Additional Risk Factors Affecting Our Interests in Enable Midstream Partners, LP — Our cash flows will be adversely impacted 
if we receive less cash distributions from Enable than we currently expect.”

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

If we are unable to arrange future financings on acceptable terms, our ability to refinance existing indebtedness could be 

limited.

Our businesses are capital intensive in nature. We depend on long-term debt to finance a portion of our capital expenditures 
and refinance our existing debt and on short-term borrowings through our revolving credit facilities and commercial paper programs 
to satisfy liquidity needs to the extent not satisfied by cash flow from our business operations. As of December 31, 2016, we had 
$8.6 billion of outstanding indebtedness on a consolidated basis, which includes $2.3 billion of non-recourse Securitization Bonds. 
As of December 31, 2016, approximately $850 million principal amount of this debt is required to be paid through 2019. This 
amount excludes principal repayments of approximately $1.3 billion on Securitization Bonds, for which dedicated revenue streams 
exist. Our future financing activities may be significantly affected by, among other things:

• 

• 

• 

• 

general economic and capital market conditions;

credit availability from financial institutions and other lenders;

volatility or fluctuations in distributions from Enable’s units or volatility in Enable’s unit price;

investor confidence in us and the markets in which we operate;

•  maintenance of acceptable credit ratings;

•  market expectations regarding our future earnings and cash flows;

• 

• 

• 

• 

our ability to access capital markets on reasonable terms;

our exposure to GenOn (formerly known as RRI Energy, Inc., Reliant Energy and RRI), a wholly-owned subsidiary of 
NRG, in connection with certain indemnification obligations;

incremental collateral that may be required due to regulation of derivatives; and

provisions of relevant tax and securities laws.

As of December 31, 2016, Houston Electric had approximately $2.6 billion aggregate principal amount of general mortgage 
bonds outstanding under the General Mortgage, including approximately $118 million held in trust to secure pollution control 
bonds for which we are obligated.  Additionally, as of December 31, 2016, Houston Electric had approximately $102 million 
aggregate principal amount of first mortgage bonds outstanding under the Mortgage. Houston Electric may issue additional general 
mortgage  bonds  on  the  basis  of  retired  bonds,  70%  of  property  additions  or  cash  deposited  with  the  trustee. Approximately 
$4.1 billion of additional first mortgage bonds and general mortgage bonds in the aggregate could be issued on the basis of retired 
bonds and 70% of property additions as of December 31, 2016. However, Houston Electric has contractually agreed that it will 
not issue additional first mortgage bonds, subject to certain exceptions.

Our current credit ratings are discussed in “Management’s Discussion and Analysis of Financial Condition and Results of 
Operations — Liquidity and Capital Resources — Other Matters — Impact on Liquidity of a Downgrade in Credit Ratings” in 
Item 7 of Part II of this report. These credit ratings may not remain in effect for any given period of time and one or more of these 
ratings may be lowered or withdrawn entirely by a rating agency. We note that these credit ratings are not recommendations to 
buy, sell or hold our securities. Each rating should be evaluated independently of any other rating. Any future reduction or withdrawal 
of one or more of our credit ratings could have a material adverse impact on our ability to access capital on acceptable terms.

An impairment of goodwill, long-lived assets, including intangible assets, and equity and cost method investments could 

reduce our earnings. 

Goodwill is recorded when the purchase price of a business exceeds the fair market value of the tangible and separately 
measurable intangible net assets. Accounting principles generally accepted in the United States of America require us to test 
goodwill for impairment on an annual basis or when events or circumstances occur indicating that goodwill might be impaired.  
Long-lived assets, including intangible assets with finite useful lives, are reviewed for impairment whenever events or changes 
in circumstances indicate that the carrying amount may not be recoverable.

For investments we account for under the equity or cost method, the impairment test considers whether the fair value of such 
investment as a whole, not the underlying net assets, has declined and whether that decline is other than temporary. For example, 
during the year ended December 31, 2015, we determined that an other than temporary decrease in the value of our equity investment 
in Enable had occurred.  This determination was based on the sustained low Enable common unit price and further declines in 
such price during the year, as well as the market outlook for continued depressed crude oil and natural gas prices impacting the 
midstream oil and gas industry.  We wrote down the value of our investment in Enable to its estimated fair value which resulted 
in impairment charges of $1,225 million for the year ended December 31, 2015. Additionally, we recorded our share, $621 million, 
of impairment charges Enable recorded for goodwill and long-lived assets, for a total impairment charge of $1,846 million. 

If Enable’s unit price, distributions or earnings were to decline to levels below those used in our impairment tests in 2015, 
and that decline is deemed to be other than temporary, we could determine that we are unable to recover the carrying value of our 
equity investment in Enable. Considerable judgment is used in determining if an impairment loss is other than temporary and the 
amount of any impairment. A sustained low Enable common unit price could result in our recording further impairment charges 
in the future. If we determine that an impairment is indicated, we would be required to take an immediate non-cash charge to 
earnings with a correlative effect on equity and balance sheet leverage as measured by debt to total capitalization. 

Poor  investment  performance  of  the  pension  plan,  factors  adversely  affecting  the  calculation  of  pension  liabilities  and 

increasing health care costs could unfavorably impact our results of operations, liquidity and financial position. 

We maintain a qualified defined benefit pension plan covering substantially all employees. Our costs of providing this plan 
are dependent upon a number of factors including the investment returns on plan assets, the level of interest rates used to calculate 
the funded status of the plan, our contributions to the plan and government regulations with respect to funding requirements and 
the calculation of plan liabilities. Funding requirements may increase and we may be required to make unplanned contributions 
in the event of a decline in the market value of plan assets, a decline in the interest rates used to calculate the present value of 
future plan obligations or government regulations that increase minimum funding requirements or the pension liability. In addition 
to affecting our funding requirements, each of these factors could adversely affect our results of operations, liquidity and financial 
position. Further, increasing health care costs and the effects of health care reform or any future legislative changes could also 
materially affect our benefit programs and costs. Our costs of providing employee benefits and related funding requirements could 
also increase materially in the future should there be a material reduction in the amount of the recovery of these costs through our 
rates or should significant delays develop in the timing of the recovery of such costs, which could adversely affect our financial 
results. 

The use of derivative contracts in the normal course of business by us, our subsidiaries or Enable could result in financial 

losses that could negatively impact our results of operations and those of our subsidiaries or Enable.

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

Risk Factors Affecting Our Electric Transmission & Distribution Business

Rate regulation of Houston Electric’s business may delay or deny Houston Electric’s ability to earn a reasonable return and 

fully recover its costs. 

Houston Electric’s rates are regulated by certain municipalities and the PUCT based on an analysis of its invested capital, its 
expenses and other factors in a test year in comprehensive base rate proceedings, subject to periodic review and adjustment using 
17

mechanisms like those discussed below. Each of these rate proceedings is subject to third-party intervention and appeal, and the 
timing of a general base rate proceeding may be out of Houston Electric’s control. The rates that Houston Electric is allowed to 
charge may not match its costs at any given time, which is referred to as “regulatory lag.”

Though several interim adjustment mechanisms have been implemented to reduce the effects of regulatory lag, such adjustment 
mechanisms  are  subject  to  the  applicable  regulatory  body’s  approval  and  are  subject  to  limitations  that  may  reduce  Houston 
Electric’s ability to adjust rates. For example, the DCRF mechanism adjusts an electric utility’s rates for increases in net distribution-
invested capital (e.g., distribution plant and intangible plant and communication equipment) since its last comprehensive base rate 
proceeding, but Houston Electric may make a DCRF filing only once per year and up to four times between comprehensive rate 
proceedings. The TCOS mechanism allows a transmission service provider to update its wholesale transmission rates to reflect 
changes in transmission-related invested capital, but is only available twice a year. 

Houston Electric can make no assurance that filings for such mechanisms will result in favorable adjustments to rates.  Further, 
the regulatory process by which rates are determined is subject to change as a result of the legislative process or rulemaking, as 
the case may be, and may not always be available or result in rates that will produce recovery of Houston Electric’s costs or enable 
Houston Electric to earn a reasonable return. In addition, changes to the interim adjustment mechanisms could result in an increase 
in regulatory lag or otherwise impact Houston Electric’s ability to recover its costs in a timely manner. To the extent the regulatory 
process does not allow Houston Electric to make a full and timely recovery of appropriate costs, its results of operations, financial 
condition and cash flows could be adversely affected.

Disruptions at power generation facilities owned by third parties could interrupt Houston Electric’s sales of transmission 

and distribution services.

Houston Electric transmits and distributes to customers of REPs electric power that the REPs obtain from power generation 
facilities owned by third parties. Houston Electric does not own or operate any power generation facilities. If power generation 
is disrupted or if power generation capacity is inadequate, Houston Electric’s sales of transmission and distribution services may 
be diminished or interrupted, and its results of operations, financial condition and cash flows could be adversely affected.

Houston Electric’s revenues and results of operations are seasonal.

A significant portion of Houston Electric’s revenues is derived from rates that it collects from each REP based on the amount 
of electricity it delivers on behalf of such REP. Thus, Houston Electric’s revenues and results of operations are subject to seasonality, 
weather  conditions  and  other  changes  in  electricity  usage,  with  revenues  generally  being  higher  during  the  warmer  months. 
Unusually mild weather in the warmer months could diminish our results of operations and harm our financial condition. Conversely, 
extreme warm weather conditions could increase our results of operations in a manner that would not likely be annually recurring.

The AMS deployed throughout Houston Electric’s service territory may experience unexpected problems with respect to the 

timely receipt of accurate metering data. 

Houston Electric has deployed an AMS throughout its service territory.  The deployment consisted, among other elements, 
of replacing existing meters with new electronic meters that record metering data at 15-minute intervals and wirelessly communicate 
that information to Houston Electric over a bi-directional communications system installed for that purpose. The AMS integrates 
equipment and computer software from various vendors to eliminate the need for physical meter readings to be taken at consumers’ 
premises, such as monthly readings for billing purposes and special readings associated with a customer’s change in REPs or the 
connection or disconnection of electric service.  Unanticipated difficulties could be encountered during the operation of the AMS, 
including failures or inadequacy of equipment or software, difficulties in integrating the various components of the AMS, changes 
in technology, cyber-security issues and factors outside the control of Houston Electric, which could result in delayed or inaccurate 
metering data that might lead to delays or inaccuracies in the calculation and imposition of delivery or other charges, which could 
have a material adverse effect on Houston Electric’s results of operations, financial condition and cash flows.

Houston Electric could be subject to higher costs and fines or other sanctions as a result of mandatory reliability standards.

The FERC has jurisdiction with respect to ensuring the reliability of electric transmission service, including transmission 
facilities  owned  by  Houston  Electric  and  other  utilities  within  ERCOT. The  FERC  has  designated  the  NERC  as  the  ERO  to 
promulgate standards, under FERC oversight, for all owners, operators and users of the bulk power system. The FERC has approved 
the delegation by the NERC of authority for reliability in ERCOT to the TRE, a functionally independent division of ERCOT.  
Compliance with the mandatory reliability standards may subject Houston Electric to higher operating costs and may result in 
increased capital expenditures.  In addition, if Houston Electric were to be found to be in noncompliance with applicable mandatory 
reliability standards, it could be subject to sanctions, including substantial monetary penalties.

18

A substantial portion of Houston Electric’s receivables is concentrated in a small number of REPs, and any delay or default 

in payment could adversely affect Houston Electric’s cash flows, financial condition and results of operations.

Houston Electric’s receivables from the distribution of electricity are collected from REPs that supply the electricity Houston 
Electric distributes to their customers. As of December 31, 2016, Houston Electric did business with approximately 64 REPs. 
Adverse economic conditions, structural problems in the market served by ERCOT or financial difficulties of one or more REPs 
could impair the ability of these REPs to pay for Houston Electric’s services or could cause them to delay such payments. Houston 
Electric depends on these REPs to remit payments on a timely basis. Applicable regulatory provisions require that customers be 
shifted to another REP or a provider of last resort if a REP cannot make timely payments. Applicable PUCT regulations significantly 
limit the extent to which Houston Electric can apply normal commercial terms or otherwise seek credit protection from firms 
desiring to provide retail electric service in its service territory, and Houston Electric thus remains at risk for payments related to 
services provided prior to the shift to another REP or the provider of last resort. The PUCT revised its regulations in 2009 to (i) 
increase the financial qualifications required of REPs that began selling power after January 1, 2009, and (ii) authorize utilities 
to defer bad debts resulting from defaults by REPs for recovery in a future rate case. A significant portion of Houston Electric’s 
billed  receivables  from  REPs  are  from  affiliates  of  NRG  and  Energy  Future  Holdings.  Houston  Electric’s  aggregate  billed 
receivables balance from REPs as of December 31, 2016 was $193 million. Approximately 33% and 12% of this amount was 
owed by affiliates of NRG and Energy Future Holdings, respectively.  In April 2014, Energy Future Holdings publicly disclosed 
that it and the substantial majority of its direct and indirect subsidiaries, excluding Oncor Electric Delivery Company LLC and 
its subsidiaries, filed voluntary petitions for relief under Chapter 11 of the United States Bankruptcy Code in the United States 
Bankruptcy Court for the District of Delaware. Any delay or default in payment by REPs could adversely affect Houston Electric’s 
cash flows, financial condition and results of operations. If a REP were unable to meet its obligations, it could consider, among 
various options, restructuring under the bankruptcy laws, in which event such REP might seek to avoid honoring its obligations, 
and claims might be made by creditors involving payments Houston Electric had received from such REP.

Risk Factors Affecting Our Natural Gas Distribution and Energy Services Businesses

Rate regulation of CERC’s business may delay or deny CERC’s ability to earn a reasonable return and fully recover its costs. 

CERC’s  rates  for  NGD  are  regulated  by  certain  municipalities  (in Texas  only)  and  state  commissions  in  the  context  of 
comprehensive base rate proceedings, i.e., general rate cases, based on an analysis of NGD’s invested capital, expenses and other 
factors in a test year (often either fully or partially historic), subject to periodic review and adjustment. A general rate case is also 
a very complex and resource intensive proceeding with a relatively long timeline for completion. Thus, the rates that CERC is 
allowed to charge may not match its costs at any given time, resulting in what is referred to as “regulatory lag.” 

Though  several  interim  rate  adjustment  mechanisms  have  been  approved  by  jurisdictional  regulatory  authorities  and 
implemented by NGD to reduce the effects of regulatory lag, such adjustment mechanisms are subject to the applicable regulatory 
body’s approval and are subject to certain limitations that may reduce NGD’s ability to adjust its rates. 

Arkansas enacted legislation in 2015 allowing public utilities to elect to have their rates regulated pursuant to a FRP, but such 
legislation provides for a utility’s base rates to be adjusted once a year.  In each of Louisiana, Mississippi and Oklahoma, NGD 
makes annual filings utilizing various formula rate mechanisms that adjust rates based on a comparison of authorized return to 
actual return to achieve the allowed return rates in those jurisdictions.  Additionally, in Minnesota, the MPUC implemented a full 
revenue decoupling pilot program in 2015, which separates approved revenues from the amount of natural gas used by its customers. 
The effectiveness of these filings and programs depends on the approval of the applicable state regulatory body.

In Texas, NGD’s Houston, South Texas, Beaumont/East Texas and Texas Coast divisions each submit annual GRIP filings to 
recover the incremental capital investments made in the preceding year. NGD must file a general rate case no later than five years 
after the initial GRIP implementation date. 

NGD can make no assurances that such filings will result in favorable adjustments to its rates.  Notwithstanding the application 
of the rate mechanisms discussed above, the regulatory process in which rates are determined may not always result in rates that 
will produce full recovery of NGD’s costs and enable NGD to earn a reasonable return on its invested capital.   Additionally, 
inherent in the regulatory process is some level of risk that jurisdictional regulatory authorities may initiate investigations of the 
prudence of operating expenses incurred or capital investments made by NGD and deny the full recovery of NGD’s cost of service 
or the full recovery of incurred natural gas costs in rates. To the extent the regulatory process does not allow NGD to make a full 
and timely recovery of appropriate costs, its results of operations, financial condition and cash flows could be adversely affected.

19

CERC’s  natural  gas  distribution  and  energy  services  businesses,  including  transportation  and  storage,  are  subject  to 
fluctuations in notional natural gas prices as well as geographic and seasonal natural gas price differentials, which could 
affect the ability of CERC’s suppliers and customers to meet their obligations or otherwise adversely affect CERC’s liquidity 
and results of operations and financial condition.

CERC is subject to risk associated with changes in the notional price of natural gas as well as geographic and seasonal natural 
gas price differentials. Increases in natural gas prices might affect CERC’s ability to collect balances due from its customers and, 
for NGD, could create the potential for uncollectible accounts expense to exceed the recoverable levels built into CERC’s tariff 
rates. In addition, a sustained period of high natural gas prices could (i) decrease demand for natural gas in the areas in which 
CERC operates, thereby resulting in decreased sales and revenues and (ii) increase the risk that CERC’s suppliers or customers 
fail  or  are  unable  to  meet  their  obligations. An  increase  in  natural  gas  prices  would  also  increase  CERC’s  working  capital 
requirements by increasing the investment that must be made in order to maintain natural gas inventory levels. Additionally, a 
decrease in natural gas prices could increase the amount of collateral that CERC must provide under its hedging arrangements.

A  decline  in  CERC’s  credit  rating  could  result  in  CERC  having  to  provide  collateral  under  its  shipping  or  hedging 

arrangements or to purchase natural gas.

If CERC’s credit rating were to decline, it might be required to post cash collateral under its shipping or hedging arrangements 
or to purchase natural gas. If a credit rating downgrade and the resultant cash collateral requirement were to occur at a time when 
CERC was experiencing significant working capital requirements or otherwise lacked liquidity, CERC’s results of operations, 
financial condition and cash flows could be adversely affected.

CERC’s revenues and results of operations are seasonal.

A substantial portion of CERC’s revenues is derived from natural gas sales. Thus, CERC’s revenues and results of operations 
are subject to seasonality, weather conditions and other changes in natural gas usage, with revenues being higher during the winter 
months.  Unusually mild weather in the winter months could diminish our results of operations and harm our financial condition.  
Conversely, extreme cold weather conditions could increase our results of operations in a manner that would not likely be annually 
recurring.

The states in which CERC provides regulated local natural gas distribution may, either through legislation or rules, adopt 
restrictions regarding organization, financing and affiliate transactions that could have significant adverse impacts on CERC’s 
ability to operate.

From time to time, proposals have been put forth in some of the states in which CERC does business to give state regulatory 
authorities increased jurisdiction and scrutiny over organization, capital structure, intracompany relationships and lines of business 
that could be pursued by registered holding companies and their affiliates that operate in those states. Some of these frameworks 
attempt to regulate financing activities, acquisitions and divestitures, and arrangements between the utilities and their affiliates, 
and to restrict the level of non-utility business that can be conducted within the holding company structure. Additionally, they may 
impose record-keeping, record access, employee training and reporting requirements related to affiliate transactions and reporting 
in the event of certain downgrading of the utility’s credit rating.

These regulatory frameworks could have adverse effects on CERC’s ability to conduct its utility operations, to finance its 
business and to provide cost-effective utility service. In addition, if more than one state adopts restrictions on similar activities, it 
may be difficult for CERC and us to comply with competing regulatory requirements.

CERC’s businesses must compete with alternate energy sources, which could result in CERC marketing less natural gas, 

which could have an adverse impact on CERC’s results of operations, financial condition and cash flows.

CERC competes primarily with alternate energy sources such as electricity and other fuel sources. In some areas, intrastate 
pipelines, other natural gas distributors and marketers also compete directly with CERC for natural gas sales to end users. In 
addition, as a result of federal regulatory changes affecting interstate pipelines, natural gas marketers operating on these pipelines 
may be able to bypass CERC’s facilities and market, sell and/or transport natural gas directly to commercial and industrial customers. 
Any reduction in the amount of natural gas marketed, sold or transported by CERC as a result of competition may have an adverse 
impact on CERC’s results of operations, financial condition and cash flows.

Risk Factors Affecting Our Interests in Enable Midstream Partners, LP 

We hold a substantial limited partnership interest in Enable (54.1% of Enable’s outstanding limited partnership interests as 
of December 31, 2016), as well as 50% of the management rights in Enable’s general partner and a 40% interest in the incentive 
distribution rights held by Enable’s general partner. As of December 31, 2016, we owned an aggregate of 14,520,000 Series A 
Preferred Units in Enable. Accordingly, our future earnings, results of operations, cash flows and financial condition will be affected 
by the performance of Enable, the amount of cash distributions we receive from Enable and the value of our interests in Enable.  
Factors that may have a material impact on Enable’s performance and cash distributions, and, hence, the value of our interests in 
Enable, include the risk factors outlined below, as well as the risks described elsewhere under “Risk Factors” that are applicable 
to Enable.

Our cash flows will be adversely impacted if we receive less cash distributions from Enable than we currently expect.

Both CERC Corp. and OGE hold their limited partnership interests in Enable in the form of both common units and subordinated 
units. We also hold Series A Preferred Units in Enable.  For its Series A Preferred Units, Enable is expected to pay $0.625 per 
Series A Preferred Unit, or $2.50 per Series A Preferred Unit on an annualized basis. However, distributions on each Series A 
Preferred Unit are not mandatory and are non-cumulative in the event distributions are not declared on the Series A Preferred 
Units.  Enable is expected to pay a minimum quarterly distribution of $0.2875 per unit, or $1.15 per unit on an annualized basis, 
on its outstanding common and subordinated units to the extent it has sufficient cash from operations after establishment of cash 
reserves and payment of fees and expenses, including payments to its general partner and its affiliates (referred to as “available 
cash”).  The principal difference between Enable’s common units and subordinated units is that in any quarter during the applicable 
subordination period, holders of the subordinated units are not entitled to receive any  distribution of available cash until the 
common units have received the minimum quarterly distribution plus any arrearages in the payment of the minimum quarterly 
distribution on common units from prior quarters. If Enable does not pay distributions on its subordinated units, its subordinated 
units will not accrue arrearages for those unpaid distributions. Accordingly, if Enable is unable to pay its minimum quarterly 
distribution, the amount of cash distributions we receive from Enable may be adversely affected.  Enable may not have sufficient 
available cash each quarter to enable it to pay the minimum quarterly distribution or to pay distributions on the Series A Preferred 
Units.  Additionally, distributions on the Series A Preferred Units reduce the amount of available cash Enable has to pay distributions 
on its common and subordinated units. The amount of cash Enable can distribute on its common and subordinated units and its 
Series A Preferred Units will principally depend upon the amount of cash it generates from its operations, which will fluctuate 
from quarter to quarter based on, among other things:

• 

• 

• 

• 

• 

the fees and gross margins it realizes with respect to the volume of natural gas, NGLs and crude oil that it handles;

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

the volume of natural gas, NGLs and crude oil it gathers, compresses, treats, dehydrates, processes, fractionates, transports 
and stores;

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

cash calls and settlements of hedging positions;

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

• 

• 

• 

• 

the level of competition from other midstream energy companies;

adverse effects of governmental and environmental regulation;

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

prevailing economic conditions.

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

• 

• 

the level and timing of its capital expenditures;

the cost of acquisitions;

21

• 

• 

• 

• 

• 

• 

• 

its debt service requirements and other liabilities;

fluctuations in its working capital needs;

its ability to borrow funds and access capital markets;

restrictions contained in its debt agreements;

the amount of cash reserves established by its general partner; 

distributions paid on its Series A Preferred Units; and

other business risks affecting its cash levels. 

The amount of cash Enable has available for distribution to us on its common and subordinated units and Series A Preferred 
Units depends primarily on its cash flow rather than on its profitability, which may prevent Enable from making distributions, 
even during periods in which Enable records net income.

The amount of cash Enable has available for distribution on its common and subordinated units and Series A Preferred Units, 
depends primarily upon its cash flows and not solely on profitability, which will be affected by non-cash items. As a result, Enable 
may make cash distributions during periods when it records losses for financial accounting purposes and may not make cash 
distributions during periods when it records net earnings for financial accounting purposes.

Enable’s Series A Preferred Units are required to be redeemed in certain circumstances if they are not eligible for trading 

on the NYSE, and Enable may not have sufficient funds to redeem its Series A Preferred Units if required to do so.

As a holder of Enable’s Series A Preferred Units, we may request that Enable list those units for trading on the NYSE. If 
Enable is unable to list the Series A Preferred Units in certain circumstances, it will be required to redeem the Series A Preferred 
Units. There can be no assurance that Enable would have sufficient financial resources available to satisfy its obligation to redeem 
the Series A Preferred Units. In addition, mandatory redemption of the Series A Preferred Units could have a material adverse 
effect on Enable’s business, financial position, results of operations and ability to make quarterly cash distributions to its unitholders.

We are not able to exercise control over Enable, which entails certain risks.

Enable is controlled jointly by CERC Corp. and OGE, who each own 50% of the management rights in the general partner 
of Enable.  The board of directors of Enable’s general partner is composed of an equal number of directors appointed by OGE and 
by us, the president and chief executive officer of Enable’s general partner and three directors who are independent as defined 
under the independence standards established by the NYSE.  Accordingly, we are not able to exercise control over Enable.

Although we jointly control Enable with OGE, we may have conflicts of interest with Enable that could subject us to claims 

that we have breached our fiduciary duty to Enable and its unitholders.

CERC Corp. and OGE each own 50% of the management rights in Enable’s general partner, as well as limited partnership 
interests in Enable, and interests in the incentive distribution rights held by Enable’s general partner.  We also hold Series A 
Preferred Units in Enable.  Conflicts of interest may arise between us and Enable and its unitholders. Our joint control of the 
general partner of Enable may increase the possibility of claims of breach of fiduciary duties including claims of conflicts of 
interest related to Enable. In resolving these conflicts, we may favor our own interests and the interests of our affiliates over the 
interests of Enable and its unitholders as long as the resolution does not conflict with Enable’s partnership agreement. These 
circumstances could subject us to claims that, in favoring our own interests and those of our affiliates, we breached a fiduciary 
duty to Enable or its unitholders.

Enable’s contracts are subject to renewal risks.

As contracts with its existing suppliers and customers expire, Enable may have to negotiate extensions or renewals of those 
contracts or enter into new contracts with other suppliers and customers. Enable may be unable to extend or renew existing contracts 
or enter into new contracts on favorable commercial terms, if at all. Depending on prevailing market conditions at the time of an 
extension or renewal, gathering and processing customers with fee based contracts may desire to enter into contracts under different 
fee arrangements. Approximately 87% of Enable’s gross margin was generated from fee-based contracts during the year ended 
December 31, 2016. Likewise, Enable’s transportation and storage customers may choose not to extend or renew expiring contracts 
22

based on the economics of the related areas of production. To the extent Enable is unable to renew or replace its expiring contracts 
on terms that are favorable, if at all, or successfully manage its overall contract mix over time, its financial position, results of 
operations and ability to make cash distributions could be adversely affected.

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

For the year ended December 31, 2016, 49% of Enable’s gathered natural gas volumes were attributable to the affiliates of 
Continental, Vine,  GeoSouthern,  XTO  Energy  and Apache  and  51%  of  its  transportation  and  storage  service  revenues  were 
attributable to affiliates of CenterPoint Energy, Spire, XTO Energy, American Electric Power Company and OGE.

The  loss  of  all  or  even  a  portion  of  the  gathering  and  processing  or  transportation  and  storage  services  for  any  of  these 
customers, the failure to extend or replace these contracts or the extension or replacement of these contracts on less favorable 
terms, as a result of competition or otherwise, could adversely affect Enable’s financial position, results of operations and ability 
to make cash distributions.

Enable’s businesses are dependent, in part, on the drilling and production decisions of others.

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

• 

• 

• 

• 

• 

• 

the availability and cost of capital; 

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

demand for natural gas, NGLs and crude oil; 

levels of reserves; 

geological considerations; 

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

• 

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

Fluctuations in energy prices can also greatly affect the development of new natural gas, NGL and crude oil reserves. Drilling 
and production activity generally decreases as commodity prices decrease. In general terms, the prices of natural gas, NGLs, crude 
oil and other hydrocarbon products fluctuate in response to changes in supply and demand, market uncertainty and a variety of 
additional factors that are beyond Enable’s control. Because of these factors, even if new natural gas, NGL or crude oil reserves 
are known to exist in areas served by Enable’s assets, producers may choose not to develop those reserves. Declines in natural 
gas, NGL or crude oil prices can have a negative impact on exploration, development and production activity and, if sustained, 
could lead to decreases in such activity.  In early 2016, natural gas and crude oil prices dropped to their lowest levels in over 10 
years. Both natural gas and crude oil prices increased moderately in the second half of 2016. Sustained low natural gas, NGL or 
crude oil prices could also lead producers to shut in production from their existing wells. Sustained reductions in exploration or 
production activity in Enable’s areas of operation could lead to further reductions in the utilization of its systems, which could 
adversely affect Enable’s financial position, results of operations and ability to make cash distributions.

23

In addition, it may be more difficult to maintain or increase the current volumes on Enable’s gathering systems and processing 
plants, as several of the formations in the unconventional resource plays in which it operates generally have higher initial production 
rates and steeper production decline curves than wells in more conventional basins. Should Enable determine that the economics 
of its gathering assets do not justify the capital expenditures needed to grow or maintain volumes associated therewith, Enable 
may reduce such capital expenditures, which could cause revenues associated with these assets to decline over time. In addition 
to capital expenditures to support growth, the steeper production decline curves associated with unconventional resource plays 
may  require  Enable  to  incur  higher  maintenance  capital  expenditures  relative  to  throughput  over  time,  which  will  reduce  its 
distributable cash flow.

Because of these and other factors, even if new reserves are known to exist in areas served by Enable’s assets, producers may 
choose not to develop those reserves. Reductions in drilling activity would result in Enable’s inability to maintain the current 
levels of throughput on its systems and could adversely affect its financial position, results of operations and ability to make cash 
distributions.

Enable’s industry is highly competitive, and increased competitive pressure could adversely affect its financial position, 

results of operations and ability to make cash distributions.

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

Enable may not be able to recover the costs of its substantial planned investment in capital improvements and additions, and 

the actual cost of such improvements and additions may be significantly higher than it anticipates.

Enable’s business plan calls for investment in capital improvements and additions. In Enable’s Form 10-K for the year ended 
December 31, 2016, Enable stated that it expects that its expansion capital could range from approximately $455 million to $575 
million and its maintenance capital could range from approximately $95 million to $125 million for the year ending December 
31, 2017. In the second quarter of 2016, Enable delayed the completion of the Wildhorse Plant, a cryogenic processing facility 
that it plans to connect to its super-header system in Garvin County, Oklahoma. Enable also plans to construct natural gas gathering 
and compression infrastructure to support producer activity.

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

24

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

Natural gas, NGL and crude oil prices are volatile, and changes in these prices could adversely affect Enable’s financial 

position, results of operations and ability to make cash distributions.

Enable’s financial position, results of operations and ability to make cash distributions could be negatively affected by adverse 
movements in the prices of natural gas, NGLs and crude oil depending on factors that are beyond Enable’s control. These factors 
include demand for  these commodities, which fluctuates with changes in  market and  economic  conditions and other factors, 
including the impact of seasonality and weather, general economic conditions, the level of domestic and offshore natural gas 
production and consumption, the availability of imported natural gas, LNG, NGLs and crude oil, actions taken by foreign natural 
gas and oil producing nations, the availability of local, intrastate and interstate transportation systems, the availability and marketing 
of competitive fuels, the impact of energy conservation efforts, technological advances affecting energy consumption and the 
extent of governmental regulation and taxation.  In early 2016, natural gas and crude oil prices dropped to their lowest levels in 
over 10 years. Both natural gas and crude oil prices increased moderately in the second half of 2016.

Enable’s natural gas processing arrangements expose it to commodity price fluctuations. In 2016, 8%, 46%, and 46% of 
Enable’s processing plant inlet volumes consisted of keep-whole arrangements, percent-of-proceeds or percent-of-liquids and fee-
based, respectively. Under a typical keep-whole arrangement, Enable processes raw natural gas, extracts the NGLs, replaces the 
extracted NGLs with a Btu equivalent amount of natural gas, delivers the processed and replacement natural gas to the producer, 
retains the NGLs and sells the NGLs for its own account. If Enable is unable to sell the NGLs extracted for more than the cost of 
the replacement natural gas, the margins on its sale of goods will be negatively affected. 

Under a typical percent-of-proceeds processing arrangement, Enable purchases raw natural gas at a cost that is based on the 
amount of natural gas and NGLs contained in the raw natural gas. Enable then processes the raw natural gas, extracts the NGLs 
and sells the processed natural gas and NGLs for its own account. If Enable is unable to sell the processed natural gas and NGLs 
for more than the cost of the raw natural gas, the margins on its sale of goods will be negatively affected.

Under a typical percent-of-liquids processing arrangement and a typical fee-based arrangement, Enable purchases a portion 
of the raw natural gas that is equivalent to the amount of NGLs it contains, processes the raw natural gas, extracts the NGLs, 
returns the processed natural gas to the producer and sells the NGLs for its own account. If Enable is unable to sell the processed 
natural gas and NGLs for more than the cost of raw natural gas, the margins on its sale of goods will be negatively affected.

At any given time, Enable’s overall portfolio of processing contracts may reflect a net short position in natural gas (meaning 
that Enable is a net buyer of natural gas) and a net long position in NGLs (meaning that Enable is a net seller of NGLs). As a 
result, Enable’s gross margin could be adversely impacted to the extent the price of NGLs decreases in relation to the price of 
natural gas.

Enable is exposed to credit risks of its customers, and any material nonpayment or nonperformance by its key customers 

could adversely affect its financial position, results of operations and ability to make cash distributions.

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

25

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

Enable has been authorized by the FERC to provide transportation and storage services at its facilities at negotiated rates. 
Generally, negotiated rates are in excess of the maximum recourse rates allowed by the FERC, but it is possible that costs to 
perform services under “negotiated rate” contracts will exceed the revenues obtained under these agreements. If this occurs, it 
could decrease the cash flow realized by Enable’s systems and, therefore, decrease the cash it has available for distribution.

 As of December 31, 2016, approximately 54% of Enable’s contracted firm transportation capacity and 44% of its contracted 
firm storage capacity was subscribed under such “negotiated rate” contracts.  These contracts generally do not include provisions 
allowing for adjustment for increased costs due to inflation, pipeline safety activities or other factors that are not tied to an applicable 
tracking mechanism authorized by the FERC. Successful recovery of any shortfall of revenue, representing the difference between 
“recourse rates” (if higher) and negotiated rates, is not assured under current FERC policies.

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

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

Enable does not own all of the land on which its pipelines and facilities are located, which could disrupt its operations.

Enable does not own all of the land on which its pipelines and facilities have been constructed, and it is therefore subject to 
the possibility of more onerous terms and/or increased costs to retain necessary land use if it does not have valid rights-of-way or 
if such rights-of-way lapse or terminate. Enable may obtain the rights to construct and operate its pipelines on land owned by third 
parties and governmental agencies for a specific period of time. A loss of these rights, through Enable’s inability to renew right-
of-way contracts or otherwise, could cause it to cease operations temporarily or permanently on the affected land, increase costs 
related to the construction and continuing operations elsewhere and adversely affect its financial position, results of operations 
and ability to make cash distributions.

Enable conducts a portion of its operations through joint ventures, which subject it to additional risks that could adversely 
affect the success of these operations and Enable’s financial position, results of operations and ability to make cash distributions.

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

Enable’s joint venture arrangements may involve risks not otherwise present when operating assets directly, including, for 

example:

•  Enable’s joint venture partners may share certain approval rights over major decisions;

•  Enable’s joint venture partners may not pay their share of the joint venture’s obligations, leaving Enable liable for their 

shares of joint venture liabilities;

26

•  Enable may be unable to control the amount of cash it will receive from the joint venture;

•  Enable may incur liabilities as a result of an action taken by its joint venture partners;

•  Enable may be required to devote significant management time to the requirements of and matters relating to the joint 

ventures;

•  Enable’s insurance policies may not fully cover loss or damage incurred by both Enable and its joint venture partners in 

certain circumstances;

•  Enable’s joint venture partners may be in a position to take actions contrary to its instructions or requests or contrary to 

its policies or objectives; and

• 

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

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

Enable’s ability to grow is dependent on its ability to access external financing sources.

Enable expects that it will distribute all of its “available cash” to its unitholders.  As a result, Enable is expected to rely 
primarily upon external financing sources, including commercial bank borrowings and the issuance of debt and equity securities, 
to fund acquisitions and expansion capital expenditures. As a result, to the extent Enable is unable to finance growth externally, 
Enable’s cash distribution policy will significantly impair its ability to grow. In addition, because Enable is expected to distribute 
all of its available cash, its growth may not be as fast as businesses that reinvest their available cash to expand ongoing operations.

To the extent Enable issues additional units in connection with any acquisitions or expansion capital expenditures, the payment 
of distributions on those additional units may increase the risk that Enable will be unable to maintain or increase its per unit 
distribution level, which in turn may impact the available cash that it has to distribute on each unit. There are no limitations in 
Enable’s partnership agreement on its ability to issue additional units, including units ranking senior to the common units. The 
incurrence of additional commercial borrowings or other debt by Enable to finance its growth strategy would result in increased 
interest expense, which in turn may negatively impact the available cash that Enable has to distribute to its unitholders.

Enable depends on access to the capital markets to fund its expansion capital expenditures. Historically, unit prices of midstream 
master limited partnerships have experienced periods of volatility. In addition, because Enable’s common units are yield-based 
securities, rising market interest rates could impact the relative attractiveness of its common units to investors. As a result of capital 
market volatility, Enable may be unable to issue equity or debt on satisfactory terms, or at all, which may limit its ability to expand 
its operations or make future acquisitions.

Enable’s debt levels may limit its flexibility in obtaining additional financing and in pursuing other business opportunities.

As of December 31, 2016, Enable had approximately $3.0 billion of long-term debt outstanding, excluding the premiums on 
their senior notes. Enable has a $1.75 billion revolving credit facility for working capital, capital expenditures and other partnership 
purposes, including acquisitions, of which $1.1 billion was available as of February 1, 2017. Enable will continue to have the 
ability to incur additional debt, subject to limitations in its credit facilities. The levels of Enable’s debt could have important 
consequences, including the following:

• 

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

27

• 

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

•  Enable’s debt level will make it more vulnerable to competitive pressures or a downturn in its business or the economy 

generally; and

•  Enable’s debt level may limit its flexibility in responding to changing business and economic conditions.

Enable’s ability to service its debt will depend upon, among other things, its future financial and operating performance, which 
will be affected by prevailing economic conditions, commodity prices and financial, business, regulatory and other factors, some 
of which are beyond Enable’s control. If operating results are not sufficient to service current or future indebtedness, Enable may 
be forced to take actions such as reducing distributions, reducing or delaying business activities, acquisitions, investments or 
capital expenditures, selling assets, restructuring or refinancing debt, or seeking additional equity capital. These actions may not 
be effected on satisfactory terms, or at all.

Enable’s  credit  facilities  contain  operating  and  financial  restrictions,  including  covenants  and  restrictions  that  may  be 
affected by events beyond Enable’s control, which could adversely affect its financial condition, results of operations and ability 
to make distributions.

Enable’s credit facilities contain customary covenants that, among other things, limit its ability to:

• 

• 

• 

permit its subsidiaries to incur or guarantee additional debt;

incur or permit to exist certain liens on assets;

dispose of assets;

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

• 

• 

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

change the nature of its business.

Enable’s credit facilities also require it to maintain certain financial ratios. Enable’s ability to meet those financial ratios can 
be affected by events beyond its control, and we cannot assure you that it will meet those ratios. In addition, Enable’s credit 
facilities contain events of default customary for agreements of this nature.

Enable’s ability to comply with the covenants and restrictions contained in its credit facilities may be affected by events 
beyond its control, including prevailing economic, financial and industry conditions. If market or other economic conditions 
deteriorate, Enable’s ability to comply with these covenants may be impaired. If Enable violates any of the restrictions, covenants, 
ratios or tests in its credit facilities, a significant portion of its indebtedness may become immediately due and payable. In addition, 
Enable’s lenders’ commitments to make further loans to it under the revolving credit facility may be suspended or terminated. 
Enable might not have, or be able to obtain, sufficient funds to make these accelerated payments.

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

Performance of Enable’s operations require that Enable obtains and maintains a number of federal and state permits, licenses 
and approvals with terms and conditions containing a significant number of prescriptive limits and performance standards in order 
to operate. All of these permits, licenses, approval limits and standards require a significant amount of monitoring, record keeping 
and reporting in order to demonstrate compliance with the underlying permit, license, approval limit or standard. Noncompliance 
or incomplete documentation of Enable’s compliance status may result in the imposition of fines, penalties and injunctive relief. 
A decision by a government agency to deny or delay the issuance of a new or existing material permit or other approval, or to 
revoke or substantially modify an existing permit or other approval, could adversely affect Enable’s ability to initiate or continue 
operations at the affected location or facility and on its financial condition, results of operations and ability to make cash distributions.

Additionally, in order to obtain permits and renewals of permits and other approvals in the future, Enable may be required to 
prepare and present data to governmental authorities pertaining to the potential adverse impact that any proposed pipeline or 
processing-related activities may have on the environment, individually or in the aggregate, including on public and Indian lands. 
28

Certain approval procedures may require preparation of archaeological surveys, endangered species studies and other studies to 
assess the environmental impact of new sites or the expansion of existing sites. Compliance with these regulatory requirements 
is expensive and significantly lengthens the time required to prepare applications and to receive authorizations.

Costs of compliance with existing environmental laws and regulations are significant, and the cost of compliance with future 
environmental laws and regulations may adversely affect Enable’s financial position, results of operations and ability to make 
cash distributions.

Enable is subject to extensive federal, state and local environmental statutes, rules and regulations relating to air quality, water 
quality, waste management, wildlife conservation, natural resources and health and safety that could, among other things, delay 
or increase its costs of construction, restrict or limit the output of certain facilities and/or require additional pollution control 
equipment and otherwise increase costs. For instance, in May 2016, the EPA issued final New Source Performance Standards 
governing methane emissions imposing more stringent controls on methane and volatile organic compounds emissions at new 
and modified oil and natural gas production, processing, storage and transmission facilities. These rules have required changes to 
Enable’s operations, including the installation of new equipment to control emissions. The EPA has also announced that it intends 
to impose methane emission standards for existing sources and has issued information collection requests to companies with 
production, gathering and boosting, gas processing, storage, and transmission facilities. Additionally, several states are pursuing 
similar measures to regulate emissions of methane from new and existing sources. There are significant capital, operating and 
other costs associated with compliance with these environmental statutes, rules and regulations. As a result of this continued 
regulatory focus, future federal and state regulations relating to Enable’s gathering and processing, transmission, and storage 
operations remain a possibility and could result in increased compliance costs on its operations. Furthermore, if new or more 
stringent federal, state or local legal restrictions are adopted in areas where Enable’s oil and natural gas exploration and production 
customers operate, they could incur potentially significant added costs to comply with such requirements, experience delays or 
curtailment in the pursuit of exploration, development, or production activities, and perhaps even be precluded from drilling wells, 
some or all of which could adversely affect demand for Enable’s services to those customers.

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

Increased regulation of hydraulic fracturing could result in reductions or delays in natural gas production by Enable’s 

customers, which could adversely affect its financial position, results of operations and ability to make cash distributions.

Hydraulic fracturing is common practice that is used by many of Enable’s customers to stimulate production of natural gas 
and crude oil from dense subsurface rock formations. The hydraulic fracturing process involves the injection of water, sand, and 
chemicals under pressure into targeted subsurface formations to fracture the surrounding rock and stimulate production. Hydraulic 
fracturing typically is regulated by state oil and natural gas commissions. In addition, certain federal agencies have proposed 
additional laws and regulations to more closely regulate the hydraulic fracturing process. For example, in May 2016, the EPA 
issued final new source performance standard requirements that impose more stringent controls on methane and volatile organic 
compounds emissions from oil and gas development and production operations, including hydraulic fracturing and other well 
completion activity.  The EPA also released the final results of its comprehensive research study on the potential adverse impacts 
that hydraulic fracturing may have on drinking water resources in December 2016. The EPA concluded that hydraulic fracturing 
activities can impact drinking water resources under some circumstances, including large volume spills and inadequate mechanical 
29

integrity of wells. The results of EPA’s study could spur action towards federal legislation and regulation of hydraulic fracturing 
or similar production operations. In past sessions, Congress has considered, but not passed, legislation to provide for federal 
regulation of hydraulic fracturing under the Safe Drinking Water Act and to require disclosure of the chemicals used in the hydraulic 
fracturing  process. The  EPA  has  issued  the  Safe Water  Drinking Act  permitting  guidance  for  hydraulic  fracturing  operations 
involving the use of diesel fuel in fracturing fluids in those states where the EPA is the permitting authority. Additionally, the 
Bureau of Land Management issued final rules to regulate hydraulic fracturing on federal lands in March 2015. Although these 
rules were struck down by a federal court in Wyoming in June 2016, an appeal of the decision is still pending. 

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

State and federal regulatory agencies recently have focused on a possible connection between the operation of injection wells 
used for oil and gas waste disposal and seismic activity. Similar concerns have been raised that hydraulic fracturing may also 
contribute to seismic activity. When caused by human activity, such events are called induced seismicity. In March 2016, the 
United  States  Geological  Survey  identified  six  states  with  the  most  significant  hazards  from  induced  seismicity,  including 
Oklahoma, Kansas, Texas, Colorado, New Mexico and Arkansas. In light of these concerns, some state regulatory agencies have 
modified their regulations or issued orders to address induced seismicity. For example, the OCC has implemented volume reduction 
plans, and at times required shut-ins, for disposal wells injecting wastewater from oil and gas operations into the Arbuckle formation. 
The OCC also recently released well completion seismicity guidelines for operators in the South Central Oklahoma Oil Province 
and  the  Sooner  Trend Anadarko  Basin  Canadian  and  Kingfisher  Counties  that  call  for  hydraulic  fracturing  operations  to  be 
suspended following earthquakes of certain magnitudes in the vicinity. Certain environmental and other groups have also suggested 
that additional federal, state and local laws and regulations may be needed to more closely regulate the hydraulic fracturing process. 
Enable cannot predict whether additional federal, state or local laws or regulations applicable to hydraulic fracturing will be enacted 
in the future and, if so, what actions any such laws or regulations would require or prohibit. Increased regulation and attention 
given to induced seismicity could lead to greater opposition to, and litigation concerning, oil and gas activities utilizing hydraulic 
fracturing or injection wells for waste disposal. Additional legislation or regulation could also lead to operational delays or increased 
operating costs for Enable’s customers, which in turn could reduce the demand for Enable’s services.

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

Enable’s operations are subject to extensive regulation by federal, state and local regulatory authorities. Changes or additional 
regulatory measures adopted by such authorities could adversely affect Enable’s financial position, results of operations and 
ability to make cash distributions.

The rates charged by several of Enable’s pipeline systems, including for interstate gas transportation service provided by its 
intrastate pipelines, are regulated by the FERC. Enable’s pipeline operations that are not regulated by the FERC may be subject 
to state and local regulation applicable to intrastate natural and transportation services. The relevant states in which Enable operates 
include North Dakota, Oklahoma, Arkansas, Louisiana, Texas, Missouri, Kansas, Mississippi, Tennessee and Illinois.

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

A change in the jurisdictional characterization of some of Enable’s assets by federal, state or local regulatory agencies or a 
change in policy by those agencies may result in increased regulation of its assets, which may cause its revenues to decline 
and operating expenses to increase.

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

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

Other Risk Factors Affecting Our Businesses or Our Interests in Enable Midstream Partners, LP

We are subject to operational and financial risks and liabilities arising from environmental laws and regulations. 

Our operations and the operations of Enable are subject to stringent and complex laws and regulations pertaining to the 
environment. As  an  owner  or  operator  of  natural  gas  pipelines,  distribution  systems  and  storage,  electric  transmission  and 
distribution systems, and the facilities that support these systems, we must comply with these laws and regulations at the federal, 
state and local levels. These laws and regulations can restrict or impact our business activities in many ways, such as:

• 

• 

• 

• 

• 

restricting the way we can handle or dispose of wastes;

limiting or prohibiting construction activities in sensitive areas such as wetlands, coastal regions, or areas inhabited by 
endangered species;

requiring  remedial  action  to  mitigate  environmental  conditions  caused  by  our  operations,  or  attributable  to  former 
operations;

enjoining the operations of facilities with permits issued pursuant to such environmental laws and regulations; and

impacting the demand for our services by directly or indirectly affecting the use or price of natural gas.

To comply with these requirements, we may need to spend substantial amounts and devote other resources from time to time 

to:

• 

• 

construct or acquire new facilities and equipment;

acquire permits for facility operations;

31

•  modify or replace existing and proposed equipment; and

• 

clean or decommission waste management areas, fuel storage facilities and other locations.

Failure to comply with these laws and regulations may trigger a variety of administrative, civil and criminal enforcement 
measures, including the assessment of monetary penalties, the imposition of remedial actions, and the issuance of orders enjoining 
future operations. Certain environmental statutes impose strict, joint and several liability for costs required to clean and restore 
sites where hazardous substances have been stored, disposed or released. Moreover, it is not uncommon for neighboring landowners 
and other third parties to file claims for personal injury and property damage allegedly caused by the release of hazardous substances 
or other waste products into the environment.

The recent trend in environmental regulation has been to place more restrictions and limitations on activities that may impact 
the environment, and thus there can be no assurance as to the amount or timing of future expenditures for environmental compliance 
or remediation, and actual future expenditures may be greater than the amounts we currently anticipate.

Our insurance coverage may not be sufficient. Insufficient insurance coverage and increased insurance costs could adversely 

impact our results of operations, financial condition and cash flows.

We currently have general liability and property insurance in place to cover certain of our facilities in amounts that we consider 
appropriate. Such policies are subject to certain limits and deductibles and do not include business interruption coverage. Insurance 
coverage may not be available in the future at current costs or on commercially reasonable terms, and the insurance proceeds 
received for any loss of, or any damage to, any of our facilities may not be sufficient to restore the loss or damage without negative 
impact on our results of operations, financial condition and cash flows.

In common with other companies in its line of business that serve coastal regions, Houston Electric does not have insurance 
covering its transmission and distribution system, other than substations, because Houston Electric believes it to be cost prohibitive. 
In the future, Houston Electric may not be able to recover the costs incurred in restoring its transmission and distribution properties 
following hurricanes or other disasters through issuance of storm restoration bonds or a change in its regulated rates or otherwise, 
or any such recovery may not be timely granted. Therefore, Houston Electric may not be able to restore any loss of, or damage 
to, any of its transmission and distribution properties without negative impact on its results of operations, financial condition and 
cash flows.

Our  operations  and  Enable’s  operations  are  subject  to  all  of  the  risks  and  hazards  inherent  in  the  gathering,  processing, 

transportation and storage of natural gas and crude oil, including:

• 

• 

• 

• 

• 

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

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

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

ruptures, fires and explosions; and 

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

Enable currently has general liability and property insurance in place to cover certain of its facilities in amounts that Enable 
considers appropriate. Such policies are subject to certain limits and deductibles.  Enable is not fully insured against all risks 
inherent in its business. These risks could result in substantial losses due to personal injury and/or loss of life, severe damage to 
and destruction of property, plant and equipment and pollution or other environmental damage. These risks may also result in 
curtailment or suspension of Enable’s operations. A natural disaster or other hazard affecting the areas in which Enable operates 
could have a material adverse effect on Enable’s operations. Enable does not have business interruption insurance coverage for 
all of its operations. Insurance coverage may not be available in the future at current costs or on commercially reasonable terms, 
and the insurance proceeds received for any loss of, or any damage to, any of Enable’s facilities may not be sufficient to restore 
the loss or damage without negative impact on its results of operations and its ability to make cash distributions.

32

We, Houston Electric and CERC could incur liabilities associated with businesses and assets that we have transferred to 

others. 

Under some circumstances, we, Houston Electric and CERC could incur liabilities associated with assets and businesses we, 
Houston Electric and CERC no longer own. These assets and businesses were previously owned by Reliant Energy, a predecessor 
of Houston Electric, directly or through subsidiaries and include:

•  merchant  energy,  energy  trading  and  REP  businesses  transferred  to  RRI  or  its  subsidiaries  in  connection  with  the 
organization and capitalization of RRI prior to its initial public offering in 2001 and now owned by affiliates of NRG; 
and

•  Texas electric generating facilities transferred to a subsidiary of Texas Genco in 2002, later sold to a third party and now 

owned by an affiliate of NRG.

In connection with the organization and capitalization of RRI (now GenOn) and Texas Genco (now an affiliate of NRG), 
those companies and/or their subsidiaries assumed liabilities associated with various assets and businesses transferred to them and 
agreed to certain indemnity agreements of CenterPoint Energy entities. Such indemnities have applied in cases such as the litigation 
arising out of sales of natural gas in California and other markets (the last remaining case involving CenterPoint Energy is now 
on appeal, following the district court’s summary judgment in favor of CES, a subsidiary of CERC Corp.) and various asbestos 
and other environmental matters that arise from time to time. GenOn has publicly disclosed that it may be unable to continue as 
a going concern and is exploring various options, including negotiations with creditors and lessors, refinancing, potential sale of 
assets, as well as the possibility of filing for protection under Chapter 11 of the U.S. Bankruptcy Code. If any of the indemnifying 
entities were unable to meet their indemnity obligations or satisfy a liability that has been assumed or if claims in one or more of 
these lawsuits were successfully asserted against us, we, Houston Electric or CERC could incur liability and be responsible for 
satisfying the liability. 

In connection with our sale of Texas Genco, the separation agreement was amended to provide that Texas Genco would no 
longer be liable for, and we would assume and agree to indemnify Texas Genco against, liabilities that Texas Genco originally 
assumed in connection with its organization to the extent, and only to the extent, that such liabilities are covered by certain insurance 
policies held by us, and in certain of the asbestos lawsuits we have agreed to continue to defend such claims to the extent they are 
covered by insurance maintained by us, subject to reimbursement of the costs of such defense by an NRG affiliate.

Cyber-attacks, physical security breaches, acts of terrorism or other disruptions could adversely impact our or Enable’s 

results of operations, financial condition and/or cash flows. 

We and Enable are subject to cyber and physical security risks related to adversaries attacking information technology systems, 
network infrastructure and facilities used to (i) manage operations and other business processes and (ii) protect sensitive information 
maintained in the normal course of business. The operation of our electric transmission and distribution system is dependent on 
not only physical interconnection of our facilities but also on communications among the various components of our system. Such 
reliance on information and communication between and among those components has increased since deployment of smart meters 
and the intelligent grid.  Similarly, our and Enable’s business operations are interconnected with external networks and facilities. 
The distribution of natural gas to our customers requires communications with Enable’s pipeline facilities and third-party systems. 
The gathering, processing and transportation of natural gas from Enable’s gathering, processing and pipeline facilities and crude 
oil gathering pipeline systems also rely on communications among its facilities and with third-party systems that may be delivering 
natural gas or crude oil into or receiving natural gas or crude oil and other products from Enable’s facilities. Disruption of those 
communications, whether caused by physical disruption such as storms or other natural phenomena, by failure of equipment or 
technology or by manmade events, such as cyber-attacks or acts of terrorism, may disrupt our or Enable’s ability to conduct 
operations and control assets. 

Cyber-attacks and unauthorized access could also result in the loss of confidential, proprietary or critical infrastructure data 
or security breaches of other information technology systems that could disrupt operations and critical business functions, adversely 
affect reputation, increase costs and subject us or Enable to possible legal claims and liability. Neither we nor Enable is fully 
insured against all cyber-security risks, any of which could have a material adverse effect on either our, or Enable’s, results of 
operations, financial condition and cash flows. 

In addition, our and Enable’s critical energy infrastructure may be targets of terrorist activities that could disrupt our respective 
business operations. Any such disruptions could result in significant costs to repair damaged facilities and implement increased 
security measures, which could have a material adverse effect on either our or Enable’s results of operations, financial condition 
and cash flows.

33

Failure to maintain the security of personally identifiable information could adversely affect us. 

In connection with our business we collect and retain personally identifiable information of our customers, shareholders and 
employees. Our customers, shareholders and employees expect that we will adequately protect their personal information, and the 
United States regulatory environment surrounding information security and privacy is increasingly demanding. A significant theft, 
loss or fraudulent use of customer, shareholder, employee or CenterPoint Energy data by cyber-crime or otherwise could adversely 
impact our reputation and could result in significant costs, fines and litigation.

Our results of operations, financial condition and cash flows may be adversely affected if we are unable to successfully 

operate our facilities or perform certain corporate functions.

Our performance depends on the successful operation of our facilities. Operating these facilities involves many risks, including:

• 

• 

• 

• 

• 

• 

operator error or failure of equipment or processes;

operating limitations that may be imposed by environmental or other regulatory requirements;

labor disputes; 

information  technology  or  financial  system  failures  that  impair  our  information  technology  infrastructure,  reporting 
systems or disrupt normal business operations;

information technology failure that affects our ability to access customer information or causes us to lose confidential or 
proprietary data that materially and adversely affects our reputation or exposes us to legal claims; and

catastrophic events such as fires, earthquakes, explosions, leaks, floods, droughts, hurricanes, terrorism, pandemic health 
events or other similar occurrences.

Such events may result in a decrease or elimination of revenue from our facilities, an increase in the cost of operating our 
facilities or delays in cash collections, any of which could have a material adverse effect on our results of operations, financial 
condition and/or cash flows.

Our success depends upon our ability to attract, effectively transition and retain key employees and identify and develop 

talent to succeed senior management.

We depend on our senior executive officers and other key personnel. Our success depends on our ability to attract, effectively 
transition and retain key personnel. The inability to recruit and retain or effectively transition key personnel or the unexpected 
loss of key personnel may adversely affect our operations. In addition, because of the reliance on our management team, our future 
success depends in part on our ability to identify and develop talent to succeed senior management. The retention of key personnel 
and appropriate senior management succession planning will continue to be critically important to the successful implementation 
of our strategies.

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

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

Climate change legislation and regulatory initiatives could result in increased operating costs and reduced demand for our 

services or Enable’s services. 

Regulatory agencies have from time to time considered adopting legislation, including modification of existing laws and 
regulations,  to  reduce  GHGs,  and  there  continues  to  be  a  wide-ranging  policy  and  regulatory  debate,  both  nationally  and 
34

internationally, regarding the potential impact of GHGs and possible means for their regulation.  Following a finding by the EPA 
that certain GHGs represent an endangerment to human health, the EPA adopted two sets of rules regulating GHG emissions under 
the Clean Air Act, one that requires a reduction in emissions of GHGs from motor vehicles and another that regulates emissions 
of GHGs from certain large stationary sources. The EPA has also expanded its existing GHG emissions reporting requirements. 
These permitting and reporting requirements could lead to further regulation of GHGs by the EPA. As a distributor and transporter 
of natural gas, or a consumer of natural gas in its pipeline and gathering businesses, CERC’s or Enable’s revenues, operating costs 
and capital requirements, as applicable, could be adversely affected as a result of any regulatory action that would require installation 
of new control technologies or a modification of its operations or would have the effect of reducing the consumption of natural 
gas.  Our electric transmission and distribution business, in contrast to some electric utilities, does not generate electricity and 
thus is not directly exposed to the risk of high capital costs and regulatory uncertainties that face electric utilities that burn fossil 
fuels to generate electricity.  Nevertheless, Houston Electric’s revenues could be adversely affected to the extent any resulting 
regulatory action has the effect of reducing consumption of electricity by ultimate consumers within its service territory. Likewise, 
incentives to conserve energy or use energy sources other than natural gas could result in a decrease in demand for our services.

Climate changes could result in more frequent and more severe weather events which could adversely affect the results of 

operations of our businesses. 

To the extent climate changes occur, our businesses may be adversely impacted, though we believe any such impacts are 
likely to occur very gradually and hence would be difficult to quantify with specificity.  To the extent global climate change results 
in warmer temperatures in our service territories, financial results from our natural gas distribution businesses could be adversely 
affected  through  lower  gas  sales,  and  Enable’s  natural  gas  gathering,  processing  and  transportation  and  crude  oil  gathering 
businesses could experience lower revenues.  Another possible result of climate change is more frequent and more severe weather 
events, such as hurricanes or tornadoes.  Since many of our facilities are located along or near the Gulf Coast, increased or more 
severe hurricanes or tornadoes could increase our costs to repair damaged facilities and restore service to our customers.  When 
we cannot deliver electricity or natural gas to customers or our customers cannot receive our services, our financial results can be 
impacted by lost revenues, and we generally must seek approval from regulators to recover restoration costs.  To the extent we 
are unable to recover those costs, or if higher rates resulting from our recovery of such costs result in reduced demand for our 
services, our future financial results may be adversely impacted.

We may be negatively impacted by changes in federal income tax policy.

The Executive and Legislative Branches of the United States Federal government have made public statements in support of 
comprehensive tax reform plans, including significant changes to corporate income tax laws. We are currently unable to predict 
whether these reform discussions will result in any significant changes to existing tax laws, or if any such changes would have a 
cumulative positive or negative impact on us or our regulatory activities.  It is possible that changes in the United States federal 
income tax laws could have an adverse effect on our or Enable’s results of operations, financial condition, and cash flows. 

CERC and Enable may incur significant costs and liabilities resulting from pipeline integrity and other similar programs 

and related repairs. 

The DOT has adopted regulations requiring pipeline operators to develop integrity management programs for transportation 
pipelines located in “high consequence areas,” which are those areas where a leak or rupture could do the most harm. The regulations 
require pipeline operators, including CERC and Enable, to, among other things:

• 

• 

• 

• 

• 

• 

• 

perform ongoing assessments of pipeline integrity;

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

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

improve data collection, integration, and analysis;

develop processes  for performance management, record keeping, management of change and communication; 

repair and remediate pipelines as necessary; and 

implement preventive and mitigating action. 

35

Recent regulatory proposals from PHMSA would expand the scope of its safety, reporting and recordkeeping requirements 
for both natural gas and hazardous liquids (including crude oil and NGLs) pipelines, as well as underground natural gas storage 
facilities.  These proposals, if finalized, would impose additional costs on us and Enable.

In March 2016, PHMSA issued a notice of proposed rulemaking detailing proposed revisions to the safety standards applicable 
to natural gas transmission and gathering pipelines. The proposed rules include significant modifications which, if adopted, will 
result in significant operational and integrity management changes.  These include requiring reconfirmation of the Maximum 
Allowable Operating Pressures in pipelines without reliable records, creating new material verification procedures, adding a new 
moderate consequence area, and tightening repair criteria for pipelines in both high and moderate consequence areas.  Other 
modifications include adding record-keeping and data collection obligations, and new requirements for monitoring gas quality 
and managing corrosion.  The proposed rules also would expand the scope of gas gathering lines subject to PHMSA regulation, 
including imposing minimum safety standards on certain larger, currently exempt, gathering lines, while subjecting all gathering-
line operators to recordkeeping and annual reporting requirements from which they are currently exempt.  Other proposed changes, 
such as the modification to the definition of a transmission line, some record-keeping requirements, and some material verification 
obligations also may impact distribution pipelines although PHMSA states that such far-reaching applicability is not its intent. 
PHMSA is currently reviewing thousands of public comments submitted in July 2016. Because the impact of these proposed rules 
remains uncertain, we are still monitoring and evaluating the effect of these proposed requirements on operations.

PHMSA also issued a similar notice of proposed rulemaking for hazardous liquid pipelines in October 2015. Both of these 
notices of proposed rulemaking would require inspections of pipeline areas affected by severe weather, natural disasters or similar 
events. In addition, the proposed hazardous liquid rule would extend PHMSA reporting requirements to all gathering lines, require 
periodic inline inspections of pipelines outside of high consequence areas, require use of leak detection systems on all hazardous 
liquid pipelines, modify applicable repair criteria and set a timeline for pipelines subject to integrity management requirements 
to be capable of accommodating inline inspection tools.  PHMSA issued the final rule for hazardous liquid pipelines on January 
13, 2017, but the rule’s eventual implementation and effectiveness are uncertain as a result of a January 20, 2017 regulatory freeze.  
We will continue to monitor the status of this rulemaking and the effect of these proposed requirements on operations.

On  December  14,  2016,  PHMSA  announced  an  interim  final  rule  to  impose  industry-developed  recommendations  as 
enforceable safety standards for downhole (underground) equipment, including wells, wellbore tubing, and casing, at both interstate 
and intrastate underground natural gas storage facilities. This rule went into effect on January 18, 2017, with a compliance deadline 
of January 18, 2018. Both CERC and Enable own and operate underground storage facilities that will be subject to this rule’s 
provisions, which include procedures and practices for operations, maintenance, threat identification, monitoring, assessment, site 
security, emergency response and preparedness, training and recordkeeping. States may also impose more stringent standards on 
intrastate storage facilities. CERC and Enable continue to assess the potential impact of this newly announced rule.

Although many of CERC’s and Enable’s  pipelines fall within a class that is currently not subject to the requirements in 
PHMSA’s  recent  proposals,  they  may  nonetheless  incur  significant  cost  and  liabilities  associated  with  repair,  remediation, 
prevention or mitigation measures associated with their non-exempt pipelines, which are subject to existing requirements.  Work 
associated with PHMSA requirements is part of CERC’s and Enable’s normal integrity management program and neither expect 
to  incur  any  extraordinary  costs  during  2017  to  complete  the  testing  required  by  existing  DOT  regulations  and  their  state 
counterparts. CERC and Enable have not estimated the costs for any repair, remediation, preventive or mitigation actions that may 
be determined to be necessary as a result of the testing program, which could be substantial, or any lost cash flows resulting from 
shutting down their pipelines during the pendency of such repairs. Should CERC or Enable fail to comply with DOT or comparable 
state regulations, they could be subject to penalties and fines. 

Aging infrastructure may lead to increased costs and disruptions in operations that could negatively impact our financial 

results.

CenterPoint Energy has risks associated with aging infrastructure assets.  The age of certain of our assets may result in a need 
for replacement, or higher level of maintenance costs as a result of our risk based federal and state compliant integrity management 
programs.  Failure to achieve timely recovery of these expenses could adversely impact revenues and could result in increased 
capital expenditures or expenses.

The operation of our facilities depends on good labor relations with our employees. 

Several of our businesses have entered into and have in place collective bargaining agreements with different labor unions. 
There are seven separate bargaining units in CenterPoint Energy, each with a unique collective bargaining agreement.  In 2016, 
Houston Electric entered into a renegotiated collective bargaining agreement with the IBEW Local 66, which is scheduled to 
expire  in  2020,  and  CERC  entered  into  two  renegotiated  collective  bargaining  agreements  with  Professional  Employees 
36

International  Union  Local  12,  which  are  scheduled  to  expire  in  2021.  Two  collective  bargaining  agreements  with  United 
Steelworkers Local 227 and United Steelworkers Local 13-1 are scheduled to expire in June and July of 2017, respectively.  The 
collective bargaining agreements with Gas Workers Union, Local 340 and the IBEW Local 949 are scheduled to expire in April 
and December of 2020, respectively. Any failure to reach an agreement on new labor contracts or to negotiate these labor contracts 
might result in strikes, boycotts or other labor disruptions. These potential labor disruptions could have a material adverse effect 
on our businesses, results of operations and/or cash flows. Labor disruptions, strikes or significant negotiated wage and benefit 
increases, whether due to union activities, employee turnover or otherwise, could have a material adverse effect on our businesses, 
results of operations and/or cash flows.

Our businesses will continue to have to adapt to technological change and may not be successful or may have to incur 

significant expenditures to adapt to technological change. 

We operate in businesses that require sophisticated data collection, processing systems, software and other technology. Some 
of the technologies supporting the industries we serve are changing rapidly. We expect that new technologies will emerge or grow 
that may be superior to, or may not be compatible with, some of our existing technologies, and may require us to make significant 
expenditures so that we can continue to provide cost-effective and reliable methods of energy delivery.  Among such technological 
advances are distributed generation resources (e.g., rooftop solar), energy storage devices and more energy-efficient buildings and 
products  designed  to  reduce  consumption. As  these  technologies  become  a  more  cost-competitive  option  over  time,  certain 
customers may choose to meet their own energy needs and subsequently decrease usage of our systems and services. 

Our future success will depend, in part, on our ability to anticipate and adapt to these technological changes in a cost-effective 
manner and to offer, on a timely basis, reliable services that meet customer demands and evolving industry standards. If we fail 
to adapt successfully to any technological change or obsolescence, or fail to obtain access to important technologies or incur 
significant expenditures in adapting to technological change, our businesses, operating results, financial condition and cash flows 
could be materially and adversely affected.

Our or Enable’s potential business strategies and strategic initiatives, including merger and acquisition activities and the 

disposition of assets or businesses, may not be completed or perform as expected.

From time to time, we and Enable have made and may continue to make acquisitions or divestitures of businesses and assets, 
form joint ventures or undertake restructurings.  However, suitable acquisition candidates or potential buyers may not continue 
to be available on terms and conditions we or Enable, as the case may be, find acceptable, or the expected benefits of completed 
acquisitions may not be realized fully or at all, or may not be realized in the anticipated timeframe. If we or Enable are unable to 
make acquisitions or if those acquisitions do not perform as anticipated, our and Enable’s future growth may be adversely affected.

Any completed or future acquisitions involve substantial risks, including the following:

• 

• 

acquired businesses or assets may not produce revenues, earnings or cash flow at anticipated levels;

acquired businesses or assets could have environmental, permitting or other problems for which contractual protections 
prove inadequate; 

•  we or Enable may assume liabilities that were not disclosed to us, that exceed our estimates, or for which our rights to 

indemnification from the seller are limited; 

•  we or Enable may be unable to integrate acquired businesses successfully and realize anticipated economic, operational 
and other benefits in a timely manner, which could result in substantial costs and delays or other operational, technical 
or financial problems; and 

• 

acquisitions, or the pursuit of acquisitions, could disrupt ongoing businesses, distract management, divert resources and 
make it difficult to maintain current business standards, controls and procedures. 

For example, the success of CERC’s acquisitions of Continuum and AEM will depend, in part, on its ability to realize the 
expected benefits, including operating efficiencies, cost savings and customer retention, from integrating Continuum and AEM 
with its existing energy services business. The integration process could be costly and time consuming and may result in the 
following challenges, among others:  

• 

unanticipated disruptions, issues or costs in integrating financial and accounting, information technology, communications 
and other systems; 

37

• 

• 

• 

potential inconsistencies in procedures, practices, policies, controls, and standards;  

possible differences in compensation arrangements, management perspectives and corporate culture; and 

loss of or difficulties retaining valuable employees or third-party relationships.    

Even with the successful integration of the businesses, CERC may not achieve the expected results. CERC anticipates that 
its acquisitions of Continuum and AEM will be accretive to earnings in 2017. Any of the factors addressed above could decrease 
or delay the projected accretive effect of the transaction. Failure to fully realize the expected benefits could adversely affect CERC’s 
results of operations, financial condition and cash flows.       

In  February  2016,  we  announced  that  we  were  exploring  the  use  of  a  REIT  business  model  for  all  or  part  of  our  utility 
businesses.  We have completed our evaluation and have decided not to pursue forming a REIT structure for our utility business 
or any part thereof at this time.  We also announced that we were evaluating strategic alternatives for our investment in Enable, 
including a sale or spin-off qualifying under Section 355 of the U.S. Internal Revenue Code, and we continue to evaluate our 
alternatives, including retaining our investment. There can be no assurances that these evaluations will result in any specific action, 
and we do not intend to disclose further developments on these initiatives unless and until our board of directors approves a specific 
action or as otherwise required.

Our business could be negatively affected as a result of the actions of activist shareholders.

Publicly traded companies have increasingly become subject to campaigns by activist investors advocating corporate actions 
such as financial restructuring, increased borrowing, special dividends, stock repurchases or even sales of assets or the entire 
company. It is possible that activist shareholders may attempt to effect such changes or acquire control over us. Responding to 
proxy contests and other actions by activist shareholders can be costly and time-consuming, disrupt our operations and divert the 
attention of our board of directors and senior management from the pursuit of business strategies, which could adversely affect 
our results of operations and financial condition. Additionally, perceived uncertainties as to our future direction as a result of 
shareholder activism or changes to the composition of the board of directors may lead to the perception of a change in the direction 
of the business, instability or lack of continuity.  This may be exploited by our competitors, cause concern to our current or potential 
customers, and make it more difficult to attract and retain qualified personnel.

Our bylaws designate the United States District Court for the Southern District of Texas or, if such court lacks jurisdiction, 
the state district court of Harris County, Texas as the sole and exclusive forum for certain types of actions and proceedings 
that may be initiated by our shareholders, which could limit our shareholders’ flexibility in obtaining a judicial forum for 
disputes with us or our directors, officers or employees.

Our bylaws provide that, unless we consent in writing to the selection of an alternative forum, the United States District Court 
for the Southern District of Texas or, if such court lacks jurisdiction, the state district court of Harris County, Texas will be the 
sole and exclusive forum for (i) any derivative action or proceeding brought on our behalf, (ii) any action asserting a claim of 
breach of a fiduciary duty owed by any director, officer or other employee of ours to us or our shareholders, (iii) any action asserting 
a claim against us or any director, officer or other employee of ours pursuant to any provision of our articles of incorporation or 
bylaws (as either may be amended from time to time) or the Texas Business Organizations Code, and (iv) any action asserting a 
claim against us or any director, officer or other employee of ours governed by the internal affairs doctrine. These exclusive forum 
provisions may limit a shareholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our 
directors,  officers  or  other  employees  or  agents,  which  may  discourage  such  lawsuits  against  us  and  our  directors,  officers, 
employees or agents. Alternatively, if a court were to find these provisions of our bylaws inapplicable to, or unenforceable in 
respect of, one or more of the specified types of actions or proceedings, we may incur additional costs associated with resolving 
such matters in other jurisdictions, which could adversely affect our business and financial condition.

We are involved in numerous legal proceedings, the outcome of which are uncertain, and resolutions adverse to us could 

negatively affect our financial results.

We are subject to numerous legal proceedings, the most significant of which are summarized in Note14 of the consolidated 
financial statements.  Litigation is subject to many uncertainties, and we cannot predict the outcome of individual matters with 
assurance. Final resolution of these matters may require additional expenditures over an extended period of time that may be in 
excess of established reserves and may have a material adverse effect on our financial results.

We are exposed to risks related to reduction in energy consumption due to factors including unfavorable economic conditions 

in our service territories, energy efficiency initiatives and use of alternative technologies.

Our businesses are affected by reduction in energy consumption due to factors including economic climate in our service 
territories, energy efficiency initiatives and use of alternative technologies, which could impact our ability to grow our customer 
base and our rate of growth. Declines in demand for electricity as a result of economic downturns in our regulated electric service 
territories will reduce overall sales and lessen cash flows, especially as industrial customers reduce production and, therefore, 
consumption of electricity. Although Houston Electric is subject to regulated allowable rates of return and recovery of certain 
costs under periodic adjustment clauses, overall declines in electricity sold as a result of economic downturn or recession could 
reduce revenues and cash flows, thereby diminishing results of operations. Additionally, prolonged economic downturns that 
negatively impact our results of operations and cash flows could result in future material impairment charges to write-down the 
carrying value of certain assets, including goodwill, to their respective fair values.

For example, our electric business is largely concentrated in Houston, Texas, where a higher percentage of employment is 
tied to the energy sector relative to other regions of the country.  Given the significant decline in energy and commodity prices in 
2015 and 2016, and resulting low commodity prices which we expect to continue in 2017, the rate of growth in employment in 
Houston has declined. In the event economic conditions further decline, the rate of growth in Houston and the other areas in which 
we operate may also deteriorate. Increases in customer defaults or delays in payment due to liquidity constraints could negatively 
impact our cash flows and financial condition.

Growth in customer accounts and growth of customer usage each directly influence demand for electricity and the need for 
additional delivery facilities. Customer growth and customer usage are affected by a number of factors outside our control, such 
as mandated energy efficiency measures, demand-side management goals, distributed generation resources and economic and 
demographic conditions, such as population changes, job and income growth, housing starts, new business formation and the 
overall level of economic activity.

Certain regulatory and legislative bodies have introduced or are considering requirements and/or incentives to reduce energy 
consumption  by  certain  dates. Additionally,  technological  advances  driven  by  federal  laws  mandating  new  levels  of  energy 
efficiency in end-use electric devices or other improvements in or applications of technology could lead to declines in per capita 
energy consumption.

Some or all of these factors, could result in a lack of growth or decline in customer demand for electricity or number of 
customers, and may result in our failure to fully realize anticipated benefits from significant capital investments and expenditures 
which could have a material adverse effect on their financial position, results of operations and cash flows.

Furthermore, we currently have energy efficiency riders in place to recover the cost of energy efficiency programs. Should 
we be required to invest in conservation measures that result in reduced sales from effective conservation, regulatory lag in adjusting 
rates for the impact of these measures could have a negative financial impact.

If we fail to maintain an effective system of internal controls, our ability to accurately report our financial condition, results 
of operations or cash flows or prevent fraud may be adversely affected. As a result, investors could lose confidence in our 
financial reporting, which could impact our businesses and the trading price of our securities.

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

Our businesses may be adversely affected by the intentional misconduct of our employees.

We are committed to living our core values of safety, integrity, accountability, initiative and respect and complying with all 
applicable laws and regulations. Despite that commitment and our efforts to prevent misconduct, it is possible for employees to 
engage in intentional misconduct, fail to uphold our core values, and violate laws and regulations for individual gain through 
contract or procurement fraud, misappropriation, bribery or corruption, fraudulent related-party transactions and serious breaches 
of our Ethics and Compliance Code and Standards of Conduct/Business Ethics policy, among other policies. If such intentional 
misconduct by employees should occur, it could result in substantial liability, higher costs, increased regulatory scrutiny and 
negative public perceptions.

Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis should be read in combination with our consolidated financial statements included in 

Item 8 herein.

Background

OVERVIEW

We are a public utility holding company. Our operating subsidiaries own and operate electric transmission and distribution 
and natural gas distribution facilities, supply natural gas to commercial and industrial customers and electric and natural gas utilities 
and own interests in Enable as described below. Our indirect, wholly-owned subsidiaries include:

•  Houston Electric, which engages in the electric transmission and distribution business in the Texas Gulf Coast area that 

includes the city of Houston; 

•  CERC Corp., which owns and operates natural gas distribution systems in six states; and

•  CES, which obtains and offers competitive variable and fixed-price physical natural gas supplies and services primarily 

to commercial and industrial customers and electric and natural gas utilities in 31 states. 

As of December 31, 2016, we also owned an aggregate of 14,520,000 Series A Preferred Units in Enable, which owns, operates 
and develops natural gas and crude oil infrastructure assets, and CERC Corp. owned approximately 54.1% of the limited partner 
interests in Enable.

Business Segments

In this Management’s Discussion and Analysis, we discuss our results from continuing operations on a consolidated basis and 
individually for each of our business segments. We also discuss our liquidity, capital resources and critical accounting policies. 
We are first and foremost an energy delivery company and it is our intention to remain focused on these segments of the energy 
business. The results of our business operations are significantly impacted by weather, customer growth, economic conditions, 
cost management, competition, rate proceedings before regulatory agencies and other actions of the various regulatory agencies 
to whose jurisdiction we are subject. Our electric transmission and distribution services are subject to rate regulation and are 
reported in the Electric Transmission & Distribution business segment, as are impacts of generation-related stranded costs and 
other true-up balances recoverable by the regulated electric utility. For further information about our Electric Transmission & 
Distribution business segment, see “Business — Our Business — Electric Transmission & Distribution” in Item 1 of Part I of this 
report.  Our natural gas distribution services are also subject to rate regulation and are reported in the Natural Gas Distribution 
business segment.  For further information about our Natural Gas Distribution business segment, see “Business — Our Business 
— Natural Gas Distribution” in Item 1 of Part I of this report.  Our Energy Services business segment includes non-rate regulated 
natural gas sales to, and transportation and storage services, for commercial and industrial customers.  For further information 
about our Energy Services business segment, see “Business — Our Business — Energy Services” in Item 1 of Part I of this report.
The results of our Midstream Investments business segment are dependent upon the results of Enable, which are driven primarily 
by the volume of natural gas, NGLs and crude oil that Enable gathers, processes and transports across its systems and other factors 
as discussed below under “— Factors Influencing Our Midstream Investments Segment.” Our Other Operations business segment 
includes office buildings and other real estate used in our business operations and other corporate operations which support all of 
our business operations.

Factors Influencing Our Businesses and Industry Trends

EXECUTIVE SUMMARY

We expect our and Enable’s businesses to continue to be affected by the key factors and trends discussed below. Our expectations 
are based on assumptions made by us and information currently available to us. To the extent our underlying assumptions about, 
or interpretations of, available information prove to be incorrect, our actual results may vary materially from our expected results. 

We are an energy delivery company. The majority of our revenues are generated from the sale of natural gas and the transmission 
and delivery of electricity by our subsidiaries. We do not own or operate electric generating facilities or make retail sales to end-
use electric customers. To assess our financial performance, our management primarily monitors operating income and cash flows 
from our business segments. Within these broader financial measures, we monitor margins, operation and maintenance expense, 
43

 
interest expense, capital spending and working capital requirements. In addition to these financial measures, we also monitor a 
number of variables that management considers important to the operation of our business segments, including the number of 
customers, throughput, use per customer, commodity prices and heating and cooling degree days. We also monitor system reliability, 
safety factors and customer satisfaction to gauge our performance.

To the extent adverse economic conditions affect our suppliers and customers, results from our energy delivery businesses 
may suffer. For example, our electric business is largely concentrated in Houston, Texas, where a higher percentage of employment 
is tied to the energy sector relative to other regions of the country.  Although Houston, Texas has a diverse economy, employment 
in the energy industry remains important. To the extent population growth is affected by lower energy prices and there is financial 
pressure on some of our customers who operate within the energy industry, there may be an impact on the growth rate of our 
customer base and overall demand.  Given the significant decline in energy and commodity prices in 2015, the rate of growth in 
employment in Houston, which had been greater than the national average, has declined and is now more in line with the national 
average.  We expect this trend to continue in the foreseeable future. Also, adverse economic conditions, coupled with concerns 
for protecting the environment, may cause consumers to use less energy or avoid expansions of their facilities, resulting in less 
demand for our services. Reviewing recent years, year-over-year meter growth for Houston Electric hit a high in 2014 at 2.4%.  
This growth slowed to 2.1% for 2015, largely as a result of the performance of the energy sector.  With some stabilization of the 
energy section in 2016, Houston Electric meter growth experienced an uptick to 2.3%.  We anticipate that this growth will continue 
at roughly 2%, in line with recent years.

Performance of our Electric Transmission & Distribution and Natural Gas Distribution business segments is significantly 
influenced by the number of customers and energy usage per customer. Weather conditions can have a significant impact on energy 
usage, and we compare our results on a weather adjusted basis. In 2016, our Houston service area experienced above normal 
warmth with episodes of flooding. Houston’s average temperature of 71.4 degrees Fahrenheit was the seventh highest (record 
2012) going back to 1889. In 2015, our Houston service area experienced some of the mildest temperatures on record during 
November and December. Every state in which we distribute natural gas had a warmer than normal winter in 2016 and 2015.  Both 
the TDU and NGD have utilized weather hedges in the past to help reduce the impact of mild weather on its financial results.  
However, only the TDU entered a weather hedge for the 2015-2016 and 2016-2017 heating seasons. NGD did not enter a weather 
hedge for the last two winter seasons as a result of NGD’s Minnesota division implementing a full decoupling pilot in July 2015.  
We also have various rate mechanisms in place that help to mitigate the impact of abnormal weather on our financial results.  Our 
long-term national trends indicate customers have reduced their energy consumption, and reduced consumption can adversely 
affect our results. However, due to more affordable energy prices and continued economic improvement in the areas we serve, the 
trend toward lower usage has slowed in some of the areas we serve. In Minnesota and Arkansas, rate adjustment mechanisms 
counter the impact of declining usage from energy efficiency improvements. In addition, in many of our service areas, particularly 
in the Houston area and Minnesota, we have benefited from growth in the number of customers.  This growth also tends to mitigate 
the effects of reduced consumption.  We anticipate that this trend will continue as the regions’ economies continue to grow.  The 
profitability of our businesses is influenced significantly by the regulatory treatment we receive from the various state and local 
regulators who set our electric and natural gas distribution rates.

Our Energy Services business segment contracts with customers for transportation, storage and sales of natural gas on an 
unregulated basis.  Its operations serve customers primarily in the central United States.  The segment benefits from favorable 
price differentials, either on a geographic basis or on a seasonal basis. While this business utilizes financial derivatives to mitigate 
the effects of price movements, it does not enter into risk management contracts for speculative purposes and maintains a low VaR 
to avoid significant financial exposures.  In 2016, CES acquired Continuum, which included approximately 13,000 customers and 
175 Bcf of gas sales.  The customer base was comprised of a mix similar to our existing business.  This acquisition helped drive 
the overall operating income increase for Energy Services in 2016 as compared to 2015, excluding mark-to-market accounting 
for derivatives. In 2015 and 2014, Energy Services exhibited strong commercial and industrial customer results while capitalizing 
on asset optimization opportunities created by basis volatility. Extreme cold weather in 2014 also increased throughput and margin 
from our weather sensitive customers. In January 2017, CES acquired AEM. For more information regarding this acquisition, see 
Note 19 to our consolidated financial statements.

The nature of our businesses requires significant amounts of capital investment, and we rely on internally generated cash, 
borrowings under our credit facilities, proceeds from commercial paper and issuances of debt and equity in the capital markets to 
satisfy these capital needs. We strive to maintain investment grade ratings for our securities to access the capital markets on terms 
we consider reasonable.  A reduction in our ratings generally would increase our borrowing costs for new issuances of debt, as 
well as borrowing costs under our existing revolving credit facilities, and may prevent us from accessing the commercial paper 
markets. Disruptions in the financial markets can also affect the availability of new capital on terms we consider attractive. In 
those circumstances, companies like us may not be able to obtain certain types of external financing or may be required to accept 
terms less favorable than they would otherwise accept. For that reason, we seek to maintain adequate liquidity for our businesses 
through existing credit facilities and prudent refinancing of existing debt. 

44

The regulation of natural gas pipelines and related facilities by federal and state regulatory agencies affects our business. In 
accordance with natural gas pipeline safety and integrity regulations, we are making, and will continue to make, significant capital 
investments in our service territories, which are necessary to help operate and maintain a safe, reliable and growing natural gas 
system.  Our  compliance  expenses  may  also  increase  as  a  result  of  preventative  measures  required  under  these  regulations. 
Consequently, new rates in the areas we serve are necessary to recover these increasing costs.

We expect to make contributions to our pension plans aggregating approximately $46 million in 2017 but may need to make 
larger contributions in subsequent years. Consistent with the regulatory treatment of such costs, we can defer the amount of pension 
expense that differs from the level of pension expense included in our base rates for our Electric Transmission & Distribution 
business segment and Natural Gas Distribution business segment in Texas. 

Factors Influencing Our Midstream Investments Segment

The results of our Midstream Investments segment are dependent upon the results of Enable, which are driven primarily by 
the volume of natural gas, NGLs and crude oil that Enable gathers, processes and transports across its systems. These volumes 
depend significantly on the level of production from natural gas wells connected to Enable’s systems across a number of U.S. mid-
continent markets. Aggregate production volumes are affected by the overall amount of oil and gas drilling and completion activities.  
Production must be maintained or increased by new drilling or other activity, because the production rate of oil and gas wells 
declines over time.

Enable expects its business to continue to be impacted by the trends affecting the midstream industry, discussed below. Enable’s 
outlook is based on its management’s assumptions regarding the impact of these trends that it has developed by interpreting the 
information currently available to them. If Enable management’s assumptions or interpretation of available information prove to 
be incorrect, Enable’s future financial condition and results of operations may differ materially from its expectations.

Enable’s business is impacted by commodity prices, which have declined and otherwise experienced significant volatility in 
recent years. In early 2016, natural gas and crude oil prices dropped to their lowest levels in over 10 years. Both natural gas and 
crude oil prices increased moderately in the second half of 2016. If current commodity prices levels persist, or if commodity price 
levels decline, Enable’s future volumes and cash flows may be negatively impacted. Commodity prices impact the drilling and 
production of natural gas and crude oil in the areas served by Enable’s systems, and the volumes on Enable’s systems are negatively 
impacted if producers decrease drilling and production in those areas served. Both Enable’s gathering and processing segment and 
its transportation and storage segment can be impacted by drilling and production. Enable’s gathering and processing segment 
primarily serves producers, and many producers utilize the services provided by its transportation and storage segment. A decrease 
in volumes will decrease cash flows from Enable’s systems. In addition, Enable’s processing arrangements expose it to commodity 
price fluctuations. Enable has attempted to mitigate the impact of commodity prices on its business by entering into hedges, 
focusing on contracting fee-based business and converting existing commodity-based contracts to fee-based contracts. 

Despite recent low commodity prices, Enable’s long-term view is that natural gas and crude oil production in the U.S. will 
increase. Over the past several years, there has been a fundamental shift in U.S. natural gas and crude oil production towards tight 
gas formations and shale plays. Advancements in technology have allowed producers to efficiently extract natural gas and crude 
oil from these formations and plays. As a result, the proven reserves of natural gas and crude oil in the U.S. have significantly 
increased and the price of natural gas and crude oil has decreased compared to historical periods.

Natural gas continues to be a critical component of energy demand in the U.S. Over the long term, Enable’s management 
believes that the prospects for continued natural gas demand are favorable and will be driven by population and economic growth, 
as well as the continued displacement of coal-fired power plants by natural gas-fired power plants due to the price of natural gas 
and stricter government environmental regulations on the mining and burning of coal. The EIA projects that the majority of domestic 
consumption growth will be in the electric power, industrial and liquefaction for export sectors where the aggregate natural gas 
demand of these sectors is expected to grow from approximately 17.8 trillion cubic feet of natural gas in 2016 to approximately 
21.0 trillion cubic feet of natural in 2040. Enable’s management believes that increasing consumption of natural gas over the long 
term in these sectors will continue to drive demand for Enable’s natural gas gathering, processing, transportation and storage 
services.

Enable may access the capital markets to fund its expansion capital expenditures. Historically, unit prices of midstream master 
limited partnerships have experienced periods of volatility. In addition, because Enable’s common units are yield-based securities, 
rising market interest rates could impact the relative attractiveness of Enable’s common units to investors. Further, fluctuations in 
energy and commodity prices can create volatility in Enable’s common unit prices, which could impact investor appetite for its 
common units. Volatility in energy and commodity prices, as well as other macro-economic factors could impact the relative 

45

attractiveness of Enable’s debt securities to investors.  As a result of capital market volatility, Enable may be unable to issue equity 
securities or debt on satisfactory terms, or at all, which may limit its ability to expand its operations or make future acquisitions.

The regulation of gathering and transmission pipelines, storage and related facilities by FERC and other federal and state 
regulatory agencies, including the DOT, has a significant impact on Enable’s business. For example, the DOT’s PHMSA has 
established  pipeline  integrity  management  programs  that  require  more  frequent  inspections  of  pipeline  facilities  and  other 
preventative  measures,  which  may  increase  its  compliance  costs  and  increase  the  time  it  takes  to  obtain  required  permits. 
Additionally, increased regulation of oil and natural gas producers, including regulation associated with hydraulic fracturing, could 
reduce regional supply of oil and natural gas and therefore throughput on Enable’s gathering systems. 

Enable relies on certain key natural gas producer customers for a significant portion of its natural gas and NGLs supply. For 
the year ended December 31, 2016, Enable’s top ten natural gas producer customers accounted for approximately 66% of its 
gathered  volumes.  These  customers  include  affiliates  of  Continental,  Vine,  GeoSouthern,  XTO  Energy,  Apache,  Tapstone, 
Chesapeake, BP Energy Company, Covey Park and Marathon. Further, Enable relies on certain key utilities and producers for a 
significant portion of its transportation and storage demand. For the year ended December 31, 2016, Enable’s top transportation 
and storage customers by revenue were affiliates of CenterPoint Energy, Spire, XTO Energy, American Electric Power Company, 
OGE, Continental, Chesapeake, Midcoast Energy Partners, EOG Resources and Entergy. 

Enable  is  exposed  to  certain  credit  risks  relating  to  its  ongoing  business  operations.  Credit  risk  includes  the  risk  that 
counterparties that owe Enable money or energy will breach their obligations. If the counterparties to these arrangements fail to 
perform, Enable may be forced to enter into alternative arrangements. In that event, Enable’s financial results could be adversely 
affected, and Enable could incur losses. Enable examines the creditworthiness of third-party customers to whom it extends credit 
and manages its exposure to credit risk through credit analysis, credit approval, credit limits and monitoring procedures, and for 
certain transactions, Enable may request letters of credit, prepayments or guarantees or seek to renegotiate its contract to reduce 
credit exposure.

Net Income.  We reported net income of $432 million ($1.00 per diluted share) for 2016 compared to a net loss of $692 million

($(1.61) per diluted share) for the same period in 2015. 

The increase in net income of $1,124 million was due to the following key factors:

•  a $1,841 million increase in equity earnings from our investment in Enable, as 2015 results included impairment charges 

of $1,846 million, discussed further in Note 10 to our consolidated financial statements;

•  a $419 million increase in the gain on our marketable securities;

•  a $26 million increase in operating income discussed below by segment; 

•  a $22 million increase in cash distributions on Series A Preferred Units included in Other Income, net shown above; 

•  a $14 million decrease in interest expense due to lower weighted average interest rates on outstanding debt; and

•  a $14 million decrease in interest expense related to lower outstanding balances of our Securitization Bonds.

These increases were partially offset by:

•  a $692 million increase in income tax expense due to higher income before tax; 

•  a $487 million increase in the loss on indexed debt securities related to the ZENS resulting from a loss of $117 million 
from the Charter merger in 2016 compared to a loss of $7 million from Verizon’s acquisition of AOL in 2015 and increased 
losses of $377 million in the underlying value of the indexed debt securities;

•  a $22 million loss on early redemption of our $300 million 6.5% senior notes otherwise due 2018 included in Other 

Income, net shown above;

49

•  a $6 million decrease in interest income due primarily to Enable’s repayment of $363 million note payable to us included 

in Other Income, net shown above; and

•  a $5 million decrease in miscellaneous other non-operating income include in Other Income, net shown above.

Income Tax Expense.  We reported an effective tax rate of 37% and 39% for the years ended December 31, 2016 and 2015, 
respectively. The effective tax rate of 39% is primarily due to lower earnings from the impairment of our investment in Enable.  
The impairment loss reduced the deferred tax liability on our investment in Enable.

2015 Compared to 2014 

Net Income.  We reported a net loss of $692 million ($(1.61) per diluted share) for 2015 compared to net income of $611 

million ($1.42 per diluted share) for the same period in 2014. 

The decrease in net income of $1,303 million was due to the following key factors:

•  a $1,941 million decrease in equity earnings of unconsolidated affiliates, which included impairment charges of $1,846 

million, discussed further in Note 10 to our consolidated financial statements; and

•  a $256 million increase in the loss on our marketable securities.

These decreases were partially offset by:

•  a $712 million decrease in income tax expense; 

•  a $160 million increase in the gain on our indexed debt securities related to the ZENS resulting from a loss of $7 million 
from Verizon’s acquisition of AOL in 2015 and increased gains of $167 million in the underlying value of the indexed 
debt securities;

•  a $13 million decrease in interest expense related to lower outstanding balances of our Securitization Bonds; 

•  a $9 million increase in proceeds received from the settlement of corporate-owned life insurance policies included in 

Other Income, net shown above; and

•  a $1 million increase in miscellaneous other non-operating income included in Other Income, net shown above.

Income Tax Expense.  We reported an effective tax rate of 39% and 31% for the years ended December 31, 2015 and 2014, 
respectively. The higher effective tax rate of 39% is primarily due to lower earnings from the impairment of our equity method 
investment in Enable. The impairment loss reduced the deferred tax liability on our investment in Enable. The effective tax rate 
of 31% for 2014 is primarily due to a $29 million tax benefit recognized upon completion of a tax basis balance sheet review and 
a $13 million reversal of previously accrued taxes as a result of final positions taken in the 2013 tax returns.  We determined the 
impact of the $29 million adjustment was not material to any prior period or the year ended December 31, 2014.

2016 Compared to 2015.  Our Electric Transmission & Distribution business segment reported operating income of $628 
million for 2016, consisting of $537 million from the TDU and $91 million related to the Bond Companies. For 2015, operating 
income totaled $607 million, consisting of $502 million from the TDU and $105 million related to the Bond Companies.  

51

 
 
 
 
TDU operating income increased $35 million due to the following key factors:

•  customer growth of $31 million from the addition of over 54,000 customers;

•  higher transmission-related revenues of $82 million, partially offset by transmission costs billed by transmission 

providers of $55 million;

•  higher equity return of $17 million, primarily due to the annual true-up of transition charges correcting for under-

collections that occurred during the preceding 12 months; and

•  rate increases of $13 million related to distribution capital investments.

These increases to operating income were partially offset by the following:

•  higher depreciation, primarily because of ongoing additions to plant in service, and other taxes of $45 million;

•  higher operating and maintenance expenses of $3 million; and

•  lower right-of-way revenues of $3 million.

2015 Compared to 2014.  Our Electric Transmission & Distribution business segment reported operating income of $607 
million for 2015, consisting of $502 million from the TDU and $105 million related to the Bond Companies. For 2014, operating 
income totaled $595 million, consisting of $477 million from the TDU and $118 million related to the Bond Companies.  

TDU operating income increased $25 million due to the following key factors:

•  higher transmission-related revenues of $81 million, which were partially offset by increased transmission costs billed 

by transmission providers of $47 million;

•  customer growth of $25 million from the addition of nearly 50,000 new customers;

•  higher usage of $17 million, primarily due to a return to normal weather; and 

•  rate increases of $5 million associated with distribution capital investments.

These increases to operating income were partially offset by the following:

•  lower equity return of $20 million, primarily related to the annual true-up of transition charges correcting for over-

collections that occurred during the preceding 12 months;

•  lower revenues from energy efficiency bonuses of $15 million, including a one-time energy efficiency remand bonus 

in 2014 of $8 million;

•  higher depreciation of $13 million; and

•  lower right-of-way revenues of $7 million.

2016 Compared to 2015.  Our Natural Gas Distribution business segment reported operating income of $303 million for 2016

compared to $273 million for 2015. 

Operating income increased $30 million primarily as a result of the following key factors:

•  rate increases of $55 million, primarily from the 2015 Minnesota rate case, including the decoupling rider, and the 

Texas GRIP filing;

•  lower bad debt expense of $12 million resulting from lower customer bills due to warmer than normal weather as well 

as credit and collections process improvements that have reduced write-offs;

•  an increase of $26 million from weather normalization adjustments, including weather-related decoupling and hedging 

activities, partially offset by $19 million of milder weather effects; and

•  customer growth of $5 million from the addition of over 35,000 new customers. 

These increases were partially offset by:

•  increased depreciation and amortization of $20 million, primarily due to ongoing additions to plant in service;

•  higher labor and benefits expenses of $11 million, primarily driven by increased pension costs; 

•  higher contract services expenses of $10 million, primarily for increased pipeline integrity, leak surveying and repair 

activities; and

•  increased operations and maintenance expenses of $8 million related to higher support services costs and other 

miscellaneous expenses.

Increased expense related to energy efficiency programs of $1 million and decreased expense related to gross receipt taxes 

of $3 million were offset by a corresponding increase/decrease in the related revenues.

53

 
 
2015 Compared to 2014.  Our Natural Gas Distribution business segment reported operating income of $273 million for 2015

compared to $287 million for 2014. 

Operating income decreased $14 million primarily as a result of the following key factors:

•  decreased usage of $25 million as a result of warmer weather compared to the prior year, partially mitigated by 

weather hedges and weather normalization adjustments;

•  higher depreciation and amortization of $22 million; and

•  increase in taxes of $2 million.

These decreases were partially offset by:

•  rate increases of $23 million;

•  increased economic activity across our footprint of $7 million, including the addition of approximately 30,000 

customers; and

•  increased other revenue of $5 million.

Decreased expense related to energy efficiency programs of $4 million and decreased expense related to gross receipt taxes 

of $10 million were offset by a corresponding decrease in the related revenues.

(1)  These numbers do not include approximately 60,100 and 9,700 natural gas customers as of December 31, 2016 and 2014, 

respectively, that are under residential and small commercial choice programs invoiced by their host utility.

2016 Compared to 2015. Our Energy Services business segment reported operating income of $20 million for 2016 compared 
to $42 million for 2015.  The decrease in operating income of $22 million was due to a $25 million decrease from mark-to-market 
accounting for derivatives associated with certain natural gas purchases and sales used to lock in economic margins. Partially 
offsetting this decrease was an increase in operating income for 2016 as compared to 2015 attributable to increased throughput 
and number of customers due to the Continuum acquisition. Operating income in 2016 also included $3 million of operation and 
maintenance expenses and $3 million of amortization expenses specifically related to the acquisition and integration of Continuum. 

54

2015 Compared to 2014. Our Energy Services business segment reported operating income of $42 million for 2015 compared 
to $52 million for 2014.  The decrease in operating income of $10 million was due to a $25 million decrease from mark-to-market 
accounting for derivatives associated with certain natural gas purchases and sales used to lock in economic margins. Offsetting 
this decrease was a $5 million reduction in operation and maintenance expenses and a $4 million benefit related to a lower inventory 
write down in 2015.  The remaining increase in operating income was primarily due to improved margins resulting from reduced 
fixed costs.

(1)  These amounts include impairment charges totaling $1,846 million composed of the impairment of our investment in 
Enable of $1,225 million and our share, $621 million, of impairment charges Enable recorded for goodwill and long-
lived assets for the year ended December 31, 2015.  This impairment is offset by $213 million of earnings for the year 
ended December 31, 2015.

(2)  We contributed our remaining 0.1% interest in SESH to Enable on June 30, 2015.

(3)  On April 16, 2014, Enable completed its initial public offering and, as a result, our limited partner interest in Enable was 
reduced from approximately 58.3% to approximately 54.7%.  On May 30, 2014, we contributed to Enable our 24.95%
interest in SESH, which increased our limited partner interest in Enable from approximately 54.7% to approximately 
55.4% and reduced our interest in SESH to 0.1%.

2016 Compared to 2015.  Our Other Operations business segment reported operating income of $8 million for 2016 compared 
to  $11  million  for  2015.   The  decrease  in  operating  income  of  $3  million  is  primarily  related  to  increased  depreciation  and 
amortization.

2015 Compared to 2014.  Our Other Operations business segment reported operating income of $11 million for 2015 compared 
to $1 million for 2014.  The increase in operating income of $10 million is primarily related to decreased administrative and 
benefits costs ($8 million), decreased depreciation and amortization ($1 million) and decreased property taxes ($1 million).

Cash Provided by Operating Activities 

Net cash provided by operating activities increased $63 million in 2016 compared to 2015 primarily due to higher net income 
after adjusting for non-cash and non-operating items ($40 million) and increased cash from other non-current items ($34 million), 
partially offset by changes in working capital ($11 million). The changes in working capital items in 2016 primarily related to 
decreased cash provided by net regulatory assets and liabilities, fuel cost under recovery and net accounts receivable/payable, 
partially offset by increased cash provided by taxes receivable, net margin deposits, non-trading derivatives and net current assets 
and liabilities.

Net cash provided by operating activities increased $468 million in 2015 compared to 2014 primarily due to changes in 
working capital ($642 million), partially offset by lower net income after adjusting for non-cash and non-operating items ($136 
million) and decreased cash from other non-current items ($38 million).  The changes in working capital items in 2015 primarily 
related to increased taxes receivable, gas storage inventory, net accounts receivable/payable, net margin deposits, net regulatory 
assets and liabilities and non-trading derivatives, partially offset by decreased net current assets and liabilities.

Cash Used in Investing Activities 

Net cash used in investing activities decreased $341 million in 2016 compared to 2015 primarily due to increased cash received 
for the repayment of notes receivable from Enable ($363 million), increased return of capital from Enable ($149 million), proceeds 
from the sale of marketable securities associated with the Charter merger ($146 million) and decreased capital expenditures ($170 
million), which were partially offset by cash used for the purchase of Series A Preferred Units ($363 million), cash used for the 
Continuum acquisition ($102 million) and increased restricted cash ($17 million).

Net  cash  used  in  investing  activities  increased  $3  million  in  2015  compared  to  2014  primarily  due  to  increased  capital 
expenditures  ($212  million),  which  were  partially  offset  by  a  return  of  capital  from  unconsolidated  affiliates  ($148  million), 
increased proceeds from sale of marketable securities ($32 million) and decreased restricted cash ($19 million).

Cash Used in Financing Activities 

Net cash used in financing activities increased $293 million in 2016 compared to 2015 primarily due to increased payments 
of long-term debt ($574 million), increased distributions to ZENS holders ($146 million), loss on reacquired debt ($22 million), 
increased payments of common stock dividends ($17 million) and debt issuance costs ($9 million), which were partially offset by 
increased proceeds from long-term debt ($400 million), increased proceeds from commercial paper ($66 million) and increased 
short-term borrowings ($8 million). 

Net cash used in financing activities increased $589 million in 2015 compared to 2014 primarily due to decreased proceeds 
from long-term debt ($600 million), increased payments of long-term debt ($107 million), increased distributions to ZENS holders 
($32 million), decreased short-term borrowings ($23 million), increased payments of common stock dividends ($18 million) and 
decreased proceeds from commercial paper ($11 million), which were partially offset by increased borrowings under our revolving 
credit facility ($200 million).

Future Sources and Uses of Cash

Our liquidity and capital requirements are affected primarily by our results of operations, capital expenditures, debt service 
requirements, tax payments, working capital needs and various regulatory actions. Our principal anticipated cash requirements 
for 2017 include the following:

• 

capital expenditures of approximately $1.5 billion;

•  maturing senior notes of $500 million;

• 

• 

• 

scheduled principal payments on Securitization Bonds of $411 million;

acquisition of AEM for approximately $140 million, including estimated working capital of $100 million; and

dividend payments on our common stock and interest payments on debt.

We expect that anticipated 2017 cash needs will be met with borrowings under our credit facilities, proceeds from commercial 
paper, proceeds from the issuance of general mortgage bonds, anticipated cash flows from operations and distributions from Enable. 
Discretionary financing or refinancing may result in the issuance of equity or debt securities in the capital markets or the arrangement 
of additional credit facilities. Issuances of equity or debt in the capital markets, funds raised in the commercial paper markets and 
additional credit facilities may not, however, be available to us on acceptable terms.

The following table sets forth our actual capital expenditures for 2016 and estimates of our capital expenditures for currently 

planned projects for 2017 through 2021:

(1)  ZENS obligations are included in the 2022 and thereafter column at their contingent principal amount as of December 31, 
2016 of $514 million.  These obligations are exchangeable for cash at any time at the option of the holders for 95% of 

57

the current value of the reference shares attributable to each ZENS ($953 million as of December 31, 2016), as discussed 
in Note 11 to our consolidated financial statements.  

(2)  We calculated estimated interest payments for long-term debt as follows: for fixed-rate debt and term debt, we calculated 
interest based on the applicable rates and payment dates; for variable-rate debt and/or non-term debt, we used interest 
rates in place as of December 31, 2016. We typically expect to settle such interest payments with cash flows from operations 
and short-term borrowings.  

(3)  For a discussion of operating leases, please read Note 15(c) to our consolidated financial statements.

(4)  In 2017, we are required to contribute approximately $39 million to our qualified pension plan. We expect to contribute 
approximately $7 million and $16 million, respectively, to our non-qualified pension and postretirement benefits plans 
in 2017. 

(5)  For a discussion of other commodity commitments, please read Note 15(a) to our consolidated financial statements.

(6)  This table does not include estimated future payments for expected future AROs. These payments are primarily estimated 
to be incurred after 2022. We record a separate liability for the fair value of AROs which totaled $205 million as of 
December 31, 2016. See Note 3(c) to our consolidated financial statements.

Off-Balance Sheet Arrangements 

Other than operating leases, we have no off-balance sheet arrangements.

Regulatory Matters 

Brazos Valley Connection Project

 Construction began in February 2017 and is proceeding as scheduled.  Houston Electric filed its updated capital costs estimates 
with the PUCT in February 2017, projecting the capital costs of the project will be $310 million, in line with the estimated range 
of approximately $270-$310 million in the PUCT’s original order.  The actual capital costs of the project will depend on final land 
acquisition costs, construction costs, and other factors.  Houston Electric expects to complete construction and energize the Brazos 
Valley Connection by June 2018.  Houston Electric is able to file for recovery of land acquisition costs through interim TCOS 
updates in advance of project completion.

Rate Change Applications

Houston Electric and CERC are routinely involved in rate change applications before state regulatory authorities.  Those 
applications include general rate cases, where the entire cost of service of the utility is assessed and reset.  In addition, Houston 
Electric is periodically involved in proceedings to adjust its capital tracking mechanisms (TCOS and DCRF) and annually files to 
adjust its EECRF.  CERC is periodically involved in proceedings to adjust its capital tracking mechanisms in Texas (GRIP), its 
cost  of  service  adjustments  in Arkansas,  Louisiana,  Mississippi,  and  Oklahoma  (FRP,  RSP,  RRA  and  PBRC),  its  decoupling 
mechanism in Minnesota, and its energy efficiency cost trackers in Arkansas, Minnesota, Mississippi and Oklahoma (EECR, CIP, 
EECR and EECR). The table below reflects significant applications pending or completed during 2016.

Other Matters

Credit Facilities

On March 4, 2016, we announced that we had refinanced our existing $2.1 billion revolving credit facilities, which would 
have expired in 2019, with new revolving credit facilities totaling an aggregate of $2.5 billion. The credit agreements evidencing 
the new revolving credit facilities provide for five-year senior unsecured revolving credit facilities in amounts of $1.6 billion for 
us, $300 million for Houston Electric and $600 million for CERC Corp. These revolving credit facilities may be drawn on by the 
companies from time to time to provide funds used for general corporate purposes and to backstop the companies’ commercial 
paper programs. The facilities may also be utilized to obtain letters of credit.

  On April 4, 2016, in connection with the refinancing of our revolving credit facilities discussed above, we increased the size 
of our commercial paper program to permit the issuance of commercial paper notes in an aggregate principal amount not to exceed 
the unused portion of our $1.6 billion facility. Our revolving credit facility backstops our commercial paper program. CERC Corp.’s 
revolving credit facility backstops its commercial paper program. 

As of February 10, 2017, we had the following facilities and outstanding balances:

credit facilities, which aggregated $2.5 billion at December 31, 2016.

(3)  Represents outstanding letters of credit of $4 million.

(4)  Represents outstanding commercial paper of $587 million and outstanding letters of credit of $4 million.

For further details related to our revolving credit facilities, please see Note 13 to our consolidated financial statements.

Borrowings under each of the three revolving credit facilities are subject to customary terms and conditions. However, there 
is no requirement that the borrower make representations prior to borrowings as to the absence of material adverse changes or 
litigation that could be expected to have a material adverse effect. Borrowings under each of the revolving credit facilities are 
subject to acceleration upon the occurrence of events of default that we consider customary.  The revolving credit facilities also 
provide for customary fees, including commitment fees, administrative agent fees, fees in respect of letters of credit and other 
fees. In each of the three revolving credit facilities, the spread to LIBOR and the commitment fees fluctuate based on the borrower’s 
credit rating.  The borrowers are currently in compliance with the various business and financial covenants in the three revolving 
credit facilities.

Long-term Debt

In 2016, we and CERC retired a combined $625 million aggregate principal amount of senior notes, Houston Electric issued 
$600 million aggregate principal amount of general mortgage bonds, and as of February 10, 2017, Houston Electric had issued 
$300 million aggregate principal amount of general mortgage bonds in 2017. For further information about our 2016 and 2017 
debt transactions, see Note 13 to our consolidated financial statements.

60

 
Securities Registered with the SEC

On January 31, 2017, CenterPoint Energy, Houston Electric and CERC Corp. filed a joint shelf registration statement with 
the SEC registering indeterminate principal amounts of Houston Electric’s general mortgage bonds, CERC Corp.’s senior debt 
securities and CenterPoint Energy’s senior debt securities and junior subordinated debt securities and an indeterminate number of 
CenterPoint Energy’s shares of common stock, shares of preferred stock, as well as stock purchase contracts and equity units. The 
joint shelf registration statement will expire on January 31, 2020.

Temporary Investments

As of February 10, 2017, we had no temporary investments.

Money Pool

We have a money pool through which the holding company and participating subsidiaries can borrow or invest on a short-
term basis. Funding needs are aggregated and external borrowing or investing is based on the net cash position. The net funding 
requirements of the money pool are expected to be met with borrowings under our revolving credit facility or the sale of our 
commercial paper.

Impact on Liquidity of a Downgrade in Credit Ratings

The interest on borrowings under our credit facilities is based on our credit rating. As of February 10, 2017, Moody’s, S&P 

and Fitch had assigned the following credit ratings to senior debt of CenterPoint Energy and certain subsidiaries:

(1)  A Moody’s rating outlook is an opinion regarding the likely direction of an issuer’s rating over the medium term.

(2)  An S&P rating outlook assesses the potential direction of a long-term credit rating over the intermediate to longer term.

(3)  A Fitch rating outlook indicates the direction a rating is likely to move over a one- to two-year period.

We cannot assure that the ratings set forth above will remain in effect for any given period of time or that one or more of these 
ratings will not be lowered or withdrawn entirely by a rating agency. We note that these credit ratings are included for informational 
purposes and are not recommendations to buy, sell or hold our securities and may be revised or withdrawn at any time by the rating 
agency. Each rating should be evaluated independently of any other rating. Any future reduction or withdrawal of one or more of 
our credit ratings could have a material adverse impact on our ability to obtain short- and long-term financing, the cost of such 
financings and the execution of our commercial strategies.

A decline in credit ratings could increase borrowing costs under our revolving credit facilities. If our credit ratings or those 
of Houston Electric or CERC Corp. had been downgraded one notch by each of the three principal credit rating agencies from the 
ratings that existed at December 31, 2016, the impact on the borrowing costs under the three revolving credit facilities would have 
been immaterial. A decline in credit ratings would also increase the interest rate on long-term debt to be issued in the capital markets 
and  could  negatively  impact  our  ability  to  complete  capital  market  transactions  and  to  access  the  commercial  paper  market.  
Additionally,  a  decline  in  credit  ratings  could  increase  cash  collateral  requirements  and  reduce  earnings  of  our  Natural  Gas 
Distribution and Energy Services business segments.

CES, a wholly-owned subsidiary of CERC Corp. operating in our  Energy Services business segment, provides natural gas 
sales and services primarily to commercial and industrial customers and electric and natural gas utilities throughout the central 
and eastern United States. To economically hedge its exposure to natural gas prices, CES uses derivatives with provisions standard 
for the industry, including those pertaining to credit thresholds. Typically, the credit threshold negotiated with each counterparty 
defines the amount of unsecured credit that such counterparty will extend to CES. To the extent that the credit exposure that a 
counterparty has to CES at a particular time does not exceed that credit threshold, CES is not obligated to provide collateral. Mark-

61

 
to-market  exposure  in  excess  of  the  credit  threshold  is  routinely  collateralized  by  CES.    Similarly,  mark-to-market  exposure 
offsetting and exceeding the credit threshold may cause the counterparty to provide collateral to CES.  As of December 31, 2016, 
the amount held by CES as collateral aggregated approximately $14 million. Should the credit ratings of CERC Corp. (as the credit 
support provider for CES) fall below certain levels, CES would be required to provide additional collateral up to the amount of 
its previously unsecured credit limit. We estimate that as of December 31, 2016, unsecured credit limits extended to CES by 
counterparties aggregated $367 million, and less than $1 million of such amount was utilized.

Pipeline tariffs and contracts typically provide that if the credit ratings of a shipper or the shipper’s guarantor drop below a 
threshold level, which is generally investment grade ratings from both Moody’s and S&P, cash or other collateral may be demanded 
from the shipper in an amount equal to the sum of three months’ charges for pipeline services plus the unrecouped cost of any 
lateral built for such shipper. If the credit ratings of CERC Corp. decline below the applicable threshold levels, CERC Corp. might 
need to provide cash or other collateral of as much as $167 million as of December 31, 2016. The amount of collateral will depend 
on seasonal variations in transportation levels.

ZENS and Securities Related to ZENS

If our creditworthiness were to drop such that ZENS holders thought our liquidity was adversely affected or the market for 
the ZENS were to become illiquid, some ZENS holders might decide to exchange their ZENS for cash. Funds for the payment of 
cash upon exchange could be obtained from the sale of the shares of TW Securities that we own or from other sources. We own 
shares of TW Securities equal to approximately 100% of the reference shares used to calculate our obligation to the holders of the 
ZENS. ZENS exchanges result in a cash outflow because tax deferrals related to the ZENS and TW Securities shares would 
typically cease when ZENS are exchanged or otherwise retired and TW Securities shares are sold. The ultimate tax liability related 
to the ZENS continues to increase by the amount of the tax benefit realized each year, and there could be a significant cash outflow 
when the taxes are paid as a result of the retirement of the ZENS.  If all ZENS had been exchanged for cash on December 31, 
2016, deferred taxes of approximately $459 million would have been payable in 2016.  If all the TW Securities had been sold on 
December 31, 2016, capital gains taxes of approximately $295 million would have been payable in 2016. 

For additional information about ZENS, see Note 11 to our consolidated financial statements.

Cross Defaults

Under our revolving credit facility, a payment default on, or a non-payment default that permits acceleration of, any indebtedness 
for borrowed money and certain other specified types of obligations (including guarantees) exceeding $125 million by us or any 
of our significant subsidiaries will cause a default.  A default by CenterPoint Energy would not trigger a default under our subsidiaries’ 
debt instruments or revolving credit facilities. 

Possible Acquisitions, Divestitures and Joint Ventures

From time to time, we consider the acquisition or the disposition of assets or businesses or possible joint ventures, strategic 
initiatives or other joint ownership arrangements with respect to assets or businesses. Any determination to take action in this 
regard will be based on market conditions and opportunities existing at the time, and accordingly, the timing, size or success of 
any efforts and the associated potential capital commitments are unpredictable. We may seek to fund all or part of any such efforts 
with proceeds from debt and/or equity issuances. Debt or equity financing may not, however, be available to us at that time due 
to a variety of events, including, among others, maintenance of our credit ratings, industry conditions, general economic conditions, 
market conditions and market perceptions.

In February 2016, we announced that we were exploring the use of a REIT business model for all or part of our utility businesses.  
We have completed our evaluation and have decided not to pursue forming a REIT structure for our utility business or any part 
thereof at this time.  We also announced that we were evaluating strategic alternatives for our investment in Enable, including a 
sale or spin-off qualifying under Section 355 of the U.S. Internal Revenue Code, and we continue to evaluate our alternatives, 
including retaining our investment. There can be no assurances that these evaluations will result in any specific action, and we do 
not intend to disclose further developments on these initiatives unless and until our board of directors approves a specific action 
or as otherwise required.

Enable Midstream Partners 

We receive quarterly cash distributions from Enable on its common and subordinated units we own.  We also receive quarterly 
cash distributions from Enable on the Series A Preferred Units we own.  A reduction in the cash distributions we receive from 

62

Enable could significantly impact our liquidity.  For additional information about cash distributions from Enable, see Notes 10 
and 19 to our consolidated financial statements.

Hedging of Interest Expense for Future Debt Issuances

During 2016 and 2017, we entered into forward interest rate agreements to hedge, in part, volatility in the U.S. treasury rates 
by reducing variability in cash flows related to interest payments.  For further information, see Note 8(a) to our consolidated 
financial statements. 

Weather Hedge

We have historically entered into partial weather hedges for certain NGD jurisdictions and Houston Electric’s service territory 
to mitigate the impact of fluctuations from normal weather.  We remain exposed to some weather risk as a result of the partial 
hedges. For more information about our weather hedges, see Note 8(a) to our consolidated financial statements. 

Collection of Receivables from REPs

Houston Electric’s receivables from the distribution of electricity are collected from REPs that supply the electricity Houston 
Electric distributes to their customers. Adverse economic conditions, structural problems in the market served by ERCOT or 
financial difficulties of one or more REPs could impair the ability of these REPs to pay for Houston Electric’s services or could 
cause them to delay such payments. Houston Electric depends on these REPs to remit payments on a timely basis, and any delay 
or default in payment by REPs could adversely affect Houston Electric’s cash flows.  In the event of a REP’s default, Houston 
Electric’s tariff provides a number of remedies, including the option for Houston Electric to request that the PUCT suspend or 
revoke the certification of the REP.  Applicable regulatory provisions require that customers be shifted to another REP or a provider 
of last resort if a REP cannot make timely payments. However, Houston Electric remains at risk for payments related to services 
provided prior to the shift to the replacement REP or the provider of last resort. If a REP were unable to meet its obligations, it 
could consider, among various options, restructuring under the bankruptcy laws, in which event such REP might seek to avoid 
honoring its obligations, and claims might be made against Houston Electric involving payments it had received from such REP.  
If a REP were to file for bankruptcy, Houston Electric may not be successful in recovering accrued receivables owed by such REP 
that are unpaid as of the date the REP filed for bankruptcy.  However, PUCT regulations authorize utilities, such as CEHE, to defer 
bad debts resulting from defaults by REPs for recovery in future rate cases, subject to a review of reasonableness and necessity.   

Other Factors that Could Affect Cash Requirements

In addition to the above factors, our liquidity and capital resources could be affected by:

• 

• 

• 

• 

• 

• 

• 

• 

cash  collateral  requirements  that  could  exist  in  connection  with  certain  contracts,  including  our  weather  hedging 
arrangements, and gas purchases, gas price and gas storage activities of our Natural Gas Distribution and Energy Services 
business segments;

acceleration of payment dates on certain gas supply contracts, under certain circumstances, as a result of increased gas 
prices and concentration of natural gas suppliers;

increased costs related to the acquisition of natural gas;

increases in interest expense in connection with debt refinancings and borrowings under credit facilities;

various legislative or regulatory actions;

incremental collateral, if any, that may be required due to regulation of derivatives;

the ability of GenOn and its subsidiaries to satisfy their obligations in respect of GenOn’s indemnity obligations to us 
and our subsidiaries;

the ability of REPs, including REP affiliates of NRG and Energy Future Holdings, to satisfy their obligations to us and 
our subsidiaries; 

63

 
 
 
 
 
 
• 

• 

• 

• 

slower  customer  payments  and  increased  write-offs  of  receivables  due  to  higher  gas  prices  or  changing  economic 
conditions;

the outcome of litigation brought by or against us;

contributions to pension and postretirement benefit plans;

restoration costs and revenue losses resulting from future natural disasters such as hurricanes and the timing of recovery 
of such restoration costs; and

• 

various other risks identified in “Risk Factors” in Item 1A of Part I of this report. 

Certain Contractual Limits on Our Ability to Issue Securities and Borrow Money

 Houston Electric has contractually agreed that it will not issue additional first mortgage bonds, subject to certain exceptions.  
For information about the total debt to capitalization financial covenants in our revolving credit facilities see Note 13 to our 
consolidated financial statements.

CRITICAL ACCOUNTING POLICIES

A critical accounting policy is one that is both important to the presentation of our financial condition and results of operations 
and  requires  management  to  make  difficult,  subjective  or  complex  accounting  estimates.  An  accounting  estimate  is  an 
approximation made by management of a financial statement element, item or account in the financial statements. Accounting 
estimates in our historical consolidated financial statements measure the effects of past business transactions or events, or the 
present status of an asset or liability. The accounting estimates described below require us to make assumptions about matters that 
are highly uncertain at the time the estimate is made. Additionally, different estimates that we could have used or changes in an 
accounting estimate that are reasonably likely to occur could have a material impact on the presentation of our financial condition, 
results of operations or cash flows. The circumstances that make these judgments difficult, subjective and/or complex have to do 
with the need to make estimates about the effect of matters that are inherently uncertain. Estimates and assumptions about future 
events and their effects cannot be predicted with certainty. We base our estimates on historical experience and on various other 
assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments. 
These estimates may change as new events occur, as more experience is acquired, as additional information is obtained and as our 
operating environment changes. Our significant accounting policies are discussed in Note 2 to our consolidated financial statements. 
We believe the following accounting policies involve the application of critical accounting estimates. Accordingly, these accounting 
estimates have been reviewed and discussed with the audit committee of the board of directors.

Accounting for Rate Regulation

Accounting guidance for regulated operations provides that rate-regulated entities account for and report assets and liabilities 
consistent with the recovery of those incurred costs in rates if the rates established are designed to recover the costs of providing 
the regulated service and if the competitive environment makes it probable that such rates can be charged and collected. Our 
Electric Transmission & Distribution business segment and our Natural Gas Distribution business segment apply this accounting 
guidance. Certain expenses and revenues subject to utility regulation or rate determination normally reflected in income are deferred 
on the balance sheet as regulatory assets or liabilities and are recognized in income as the related amounts are included in service 
rates and recovered from or refunded to customers.  Regulatory assets and liabilities are recorded when it is probable that these 
items  will  be  recovered  or  reflected  in  future  rates.  Determining  probability  requires  significant  judgment  on  the  part  of 
management and includes, but is not limited to, consideration of testimony presented in regulatory hearings, proposed regulatory 
decisions, final regulatory orders and the strength or status of applications for rehearing or state court appeals.  If events were to 
occur that would make the recovery of these assets and liabilities no longer probable, we would be required to write off or write 
down these regulatory assets and liabilities.  As of December 31, 2016, we had recorded regulatory assets of $2.7 billion and 
regulatory liabilities of $1.3 billion.

Impairment of Long-Lived Assets, Including Identifiable Intangibles, Goodwill and Equity Method Investments

We  review  the  carrying  value  of  our  long-lived  assets,  including  identifiable  intangibles,  goodwill  and  equity  method 
investments whenever events or changes in circumstances indicate that such carrying values may not be recoverable, and at least 
annually for goodwill as required by accounting guidance for goodwill and other intangible assets.  Unforeseen events and changes 
in market conditions could have a material effect on the value of long-lived assets, including intangibles, goodwill and equity 

64

 
 
 
method investments due to changes in estimates of future cash flows, interest rate and regulatory matters and could result in an 
impairment charge. A loss in value of an equity method investment is recognized when the decline is deemed to be other than 
temporary. We recorded no goodwill impairments during 2016, 2015 and 2014.  We did not record material impairments to long-
lived assets, including intangibles during 2016, 2015, and 2014.  We recorded impairments totaling $1,225 million to our equity 
method investments during 2015 and no impairment during 2016 and 2014.  See Notes 9 and 10 to our consolidated financial 
statements for further discussion of the impairments recorded to our equity method investment in 2015.

We performed our annual goodwill impairment test in the third quarter of 2016 and determined, based on the results of the 
first step, using the income approach, no impairment charge was required for any reporting unit.  Our reporting units approximate 
our reportable segments.

Fair value is the amount at which the asset could be bought or sold in a current transaction between willing parties and may 
be estimated using a number of techniques, including quoted market prices or valuations by third parties, present value techniques 
based on estimates of cash flows, or multiples of earnings or revenue performance measures. The fair value of the asset could be 
different using different estimates and assumptions in these valuation techniques.

The determination of fair value requires significant assumptions by management which are subjective and forward-looking 
in nature. To assist in making these assumptions, we utilized a third-party valuation specialist in both determining and testing key 
assumptions used in the valuation of each of our reporting units. We based our assumptions on projected financial information 
that we believe is reasonable; however, actual results may differ materially from those projections. These projected cash flows 
factor in planned growth initiatives, and for our Natural Gas Distribution reporting unit, the regulatory environment. The fair 
values of our Natural Gas Distribution and Energy Services reporting units significantly exceeded the carrying values. 

Although there was not a goodwill asset impairment in our 2016 annual test, an interim impairment test could be triggered 
by the following: actual earnings results that are materially lower than expected, significant adverse changes in the operating 
environment, an increase in the discount rate, changes in other key assumptions which require judgment and are forward looking 
in nature, or if our market capitalization falls below book value for an extended period of time. No impairment triggers were 
identified subsequent to our 2016 annual test.

During the year ended December 31, 2015, we determined  that an other than temporary decrease in the value of our investment 
in Enable had occurred. The impairment analysis compared the estimated fair value of our investment in Enable to its carrying 
value. The fair value of the investment was determined using multiple valuation methodologies under both the market and income 
approaches.

Key assumptions in the market approach include recent market transactions of comparable companies and EBITDA to total 
enterprise multiples for comparable companies. Due to volatility of the quoted price of Enable’s common units, a volume weighted 
average price was used under the market approach to best approximate fair value at the measurement date. Key assumptions in 
the income approach include Enable’s forecasted cash distributions, projected cash flows of incentive distribution rights, forecasted 
growth rate of Enable’s cash distributions beyond 2020, and the discount rate used to determine the present value of the estimated 
future cash flows. A weighing of the different approaches was utilized to determine the estimated fair value of our investment in 
Enable.

As a result of the analysis, we recorded other than temporary impairments on our equity method investment in Enable of 
$1,225 million during the year ended December 31, 2015. We based our assumptions on projected financial information that we 
believe is reasonable; however, actual results may differ materially from those projections. It is reasonably possible that the estimate 
of the impairment of our equity method investment in Enable will change in the near term due to the following: actual Enable 
cash distribution is materially lower than expected, significant adverse changes in Enable’s operating environment, increase in 
the discount rate, and changes in other key assumptions which require judgment and are forward-looking in nature.  

Unbilled Energy Revenues

Revenues related to electricity delivery and natural gas sales and services are generally recognized upon delivery to customers. 
However, the determination of deliveries to individual customers is based on the reading of their meters, which is performed on 
a systematic basis throughout the month either electronically through AMS meter communications or manual readings. At the end 
of each month, deliveries to non-AMS customers since the date of the last meter reading are estimated and the corresponding 
unbilled revenue is estimated. Information regarding deliveries to AMS customers after the last billing is obtained from actual 
AMS meter usage data. Unbilled electricity delivery revenue is estimated each month based on actual AMS meter data, daily 
supply volumes and applicable rates.  Unbilled natural gas sales are estimated based on estimated purchased gas volumes, estimated 
lost and unaccounted for gas and tariffed rates in effect. As additional information becomes available, or actual amounts are 
65

determinable, the recorded estimates are revised. Consequently, operating results can be affected by revisions to prior accounting 
estimates.

Pension and Other Retirement Plans

We sponsor pension and other retirement plans in various forms covering all employees who meet eligibility requirements. 
We use several statistical and other factors that attempt to anticipate future events in calculating the expense and liability related 
to  our  plans.  These  factors  include  assumptions  about  the  discount  rate,  expected  return  on  plan  assets  and  rate  of  future 
compensation increases as estimated by management, within certain guidelines. In addition, our actuarial consultants use subjective 
factors such as withdrawal and mortality rates. The actuarial assumptions used may differ materially from actual results due to 
changing market and economic conditions, higher or lower withdrawal rates or longer or shorter life spans of participants. These 
differences  may  result  in  a  significant  impact  to  the  amount  of  pension  expense  recorded.  Please  read  “— Other  Significant 
Matters — Pension Plans” for further discussion.

NEW ACCOUNTING PRONOUNCEMENTS

See Note 2(o) to our consolidated financial statements , incorporated herein by reference, for a discussion of new accounting 

pronouncements that affect us.

OTHER SIGNIFICANT MATTERS

Pension Plans.  As discussed in Note 7(b) to our consolidated financial statements, we maintain a non-contributory qualified 
defined benefit pension plan covering substantially all employees. Employer contributions for the qualified plan are based on 
actuarial computations that establish the minimum contribution required under ERISA and the maximum deductible contribution 
for income tax purposes.

Under the terms of our pension plan, we reserve the right to change, modify or terminate the plan. Our funding policy is to 

review amounts annually and contribute an amount at least equal to the minimum contribution required under ERISA.

The minimum funding requirements for the qualified pension plan were $-0-, $-0- and $87 million for 2016, 2015 and 2014, 
respectively. We made contributions of $-0-, $35 million and $87 million in 2016, 2015 and 2014 for the respective years.  We 
are expected to make contributions aggregating approximately $39 million in 2017.

Additionally, we maintain an unfunded non-qualified benefit restoration plan that allows participants to receive the benefits 
to which they would have been entitled under our non-contributory pension plan except for the federally mandated limits on 
qualified plan benefits or on the level of compensation on which qualified plan benefits may be calculated. Employer contributions 
for the non-qualified benefit restoration plan represent benefit payments made to participants and totaled $9 million, $31 million 
and $10 million in 2016, 2015 and 2014, respectively.  We expect to make contributions aggregating approximately $7 million in 
2017.

Changes in pension obligations and assets may not be immediately recognized as pension expense in the income statement, 
but generally are recognized in future years over the remaining average service period of plan participants. As such, significant 
portions of pension expense recorded in any period may not reflect the actual level of benefit payments provided to plan participants.

As the sponsor of a plan, we are required to (a) recognize on our balance sheet as an asset a plan’s over-funded status or as a 
liability such plan’s under-funded status, (b) measure a plan’s assets and obligations as of the end of our fiscal year and (c) recognize 
changes in the funded status of our plans in the year that changes occur through adjustments to other comprehensive income and 
regulatory assets.

The projected benefit obligation for all defined benefit pension plans was $2,197 million and $2,193 million as of December 31, 

2016 and 2015, respectively. 

As of December 31, 2016, the projected benefit obligation exceeded the market value of plan assets of our pension plans by 
$541 million. Changes in interest rates or the market values of the securities held by the plan during 2017 could materially, positively 
or negatively, change our funded status and affect the level of pension expense and required contributions.

Pension cost was $102 million, $90 million and $77 million for 2016, 2015 and 2014, respectively, of which $67 million, 
$59 million and $71 million impacted pre-tax earnings, respectively. Included in the 2015 and 2014 pension costs were a $10 
million settlement charge and a $6 million curtailment loss, respectively, as discussed below. 

66

A one-time, non-cash settlement charge is required when lump sum distributions or other settlements of plan benefit obligations 
during the year exceed the service cost and interest cost components of net periodic cost for the year. Due to the amount of lump 
sum payment distributions from the non-qualified pension plan during the year ended December 31, 2015, CenterPoint Energy 
recognized a non-cash settlement charge of $10 million.  This charge is an acceleration of costs that would otherwise be recognized 
in future periods. 

The calculation of pension expense and related liabilities requires the use of assumptions. Changes in these assumptions can 
result in different expense and liability amounts, and future actual experience can differ from the assumptions. Two of the most 
critical assumptions are the expected long-term rate of return on plan assets and the assumed discount rate.

As of December 31, 2016, our qualified pension plan had an expected long-term rate of return on plan assets of 6.0%, which 
is a 0.25% decrease from the rate assumed as of December 31, 2015 due to lower expected capital market return rates. The expected 
rate of return assumption was developed using the targeted asset allocation of our plans and the expected return for each asset 
class. We regularly review our actual asset allocation and periodically rebalance plan assets to reduce volatility and better match 
plan assets and liabilities.

As of December 31, 2016, the projected benefit obligation was calculated assuming a discount rate of 4.15%, which is 0.25% 
lower than the 4.40% discount rate assumed as of December 31, 2015. The discount rate was determined by reviewing yields on 
high-quality bonds that receive one of the two highest ratings given by a recognized rating agency and the expected duration of 
pension obligations specific to the characteristics of our plan.

Pension cost for 2017, including the benefit restoration plan, is estimated to be $95 million, of which we expect approximately
$65 million to impact pre-tax earnings, based on an expected return on plan assets of 6.0% and a discount rate of 4.15% as of 
December 31, 2016. If the expected return assumption were lowered by 0.50% from 6.00% to 5.50%, 2017 pension cost would 
increase by approximately $8 million. 

As of December 31, 2016, the pension plan projected benefit obligation, including the unfunded benefit restoration plan, 
exceeded plan assets by $541 million.  If the discount rate were lowered by 0.50% from 4.15% to 3.65%, the assumption change 
would  increase  our  projected  benefit  obligation  by  approximately  $120 million  and  decrease  our  2017  pension  expense  by 
approximately $2 million. The expected reduction in pension expense due to the decrease in discount rate is a result of the expected 
correlation between the reduced interest rate and appreciation of fixed income assets in pension plans with significantly more 
fixed income instruments than equity instruments. In addition, the assumption change would impact our Consolidated Balance 
Sheet  by  increasing  the  regulatory  asset  recorded  as  of  December 31,  2016  by  $106 million  and  would  result  in  a  charge  to 
comprehensive income in 2016 of $9 million, net of tax. 

Future changes in plan asset returns, assumed discount rates and various other factors related to the pension plans will impact 

our future pension expense and liabilities. We cannot predict with certainty what these factors will be in the future.

Item 7A.     Quantitative and Qualitative Disclosures About Market Risk

Impact of Changes in Interest Rates, Equity Prices and Energy Commodity Prices

We are exposed to various market risks. These risks arise from transactions entered into in the normal course of business and 
are inherent in our consolidated financial statements. Most of the revenues and income from our business activities are affected 
by market risks. Categories of market risk include exposure to commodity prices through non-trading activities, interest rates and 
equity prices. A description of each market risk is set forth below:

• 

Interest rate risk primarily results from exposures to changes in the level of borrowings and changes in interest rates.

•  Equity price risk results from exposures to changes in prices of individual equity securities.

•  Commodity price risk results from exposures to changes in spot prices, forward prices and price volatilities of commodities, 

such as natural gas, NGLs and other energy commodities.

Management has established comprehensive risk management policies to monitor and manage these market risks. 

67

Interest Rate Risk

 As of December 31, 2016, we had outstanding long-term debt, lease obligations and obligations under our ZENS that subject 

us to the risk of loss associated with movements in market interest rates.  

Our floating rate obligations aggregated $1.4 billion and $1.1 billion as of December 31, 2016 and 2015, respectively.  If the 
floating interest rates were to increase by 10% from December 31, 2016 rates, our combined interest expense would increase by 
$1 million annually.

As of December 31, 2016 and 2015, we had outstanding fixed-rate debt (excluding indexed debt securities) aggregating $7.1 
billion and $7.5 billion, respectively, in principal amount and having a fair value of $7.5 billion and $8.0 billion, respectively. 
Because these instruments are fixed-rate, they do not expose us to the risk of loss in earnings due to changes in market interest 
rates (see  Note  13 to  our  consolidated financial statements).  However,  the  fair  value of  these instruments  would increase by 
approximately $207 million if interest rates were to decline by 10% from their levels at December 31, 2016. In general, such an 
increase in fair value would impact earnings and cash flows only if we were to reacquire all or a portion of these instruments in 
the open market prior to their maturity.

As discussed in Note 11 to our consolidated financial statements, the ZENS obligation is bifurcated into a debt component 
and a derivative component. The debt component of $114 million at December 31, 2016 was a fixed-rate obligation and, therefore, 
did not expose us to the risk of loss in earnings due to changes in market interest rates. However, the fair value of the debt component 
would increase by approximately $18 million if interest rates were to decline by 10% from levels at December 31, 2016. Changes 
in the fair value of the derivative component, a $717 million recorded liability at December 31, 2016, are recorded in our Statements 
of Consolidated Income and, therefore, we are exposed to changes in the fair value of the derivative component as a result of 
changes in the underlying risk-free interest rate. If the risk-free interest rate were to increase by 10% from December 31, 2016
levels, the fair value of the derivative component liability would increase by approximately $4 million, which would be recorded 
as an unrealized loss in our Statements of Consolidated Income.

Equity Market Value Risk

We are exposed to equity market value risk through our ownership of 7.1 million shares of TW Common, 0.9 million shares 
of Time Common and 0.9 million shares of Charter Common, which we hold to facilitate our ability to meet our obligations under 
the ZENS. See Note 11 to our consolidated financial statements for a discussion of our ZENS obligation. Changes in the fair value 
of the TW Securities held by CenterPoint Energy are expected to substantially offset changes in the fair value of the derivative 
component of the ZENS. A decrease of 10% from the December 31, 2016 aggregate market value of these shares would result in 
a net loss of approximately $2 million, which would be recorded as an unrealized loss in our Statements of Consolidated Income.

Commodity Price Risk From Non-Trading Activities

We manage these risk exposures through the implementation of our risk management policies and framework. We manage 
our commodity price risk exposures through the use of derivative financial instruments and derivative commodity instrument 
contracts. During the normal course of business, we review our hedging strategies and determine the hedging approach we deem 
appropriate based upon the circumstances of each situation.

Derivative instruments such as futures, forward contracts, swaps and options derive their value from underlying assets, indices, 
reference rates or a combination of these factors. These derivative instruments include negotiated contracts, which are referred to 
as over-the-counter derivatives, and instruments that are listed and traded on an exchange.

Derivative transactions are entered into in our non-trading operations to manage and hedge certain exposures, such as exposure 
to changes in natural gas prices. We believe that the associated market risk of these instruments can best be understood relative 
to the underlying assets or risk being hedged.

We use derivative instruments as economic hedges to offset the commodity price exposure inherent in our businesses. The 
stand-alone commodity risk created by these instruments, without regard to the offsetting effect of the underlying exposure these 
instruments are intended to hedge, is described below. We measure the commodity risk of our non-trading energy derivatives using 
a sensitivity analysis. The sensitivity analysis performed on our non-trading energy derivatives measures the potential loss in fair 
value based on a hypothetical 10% movement in energy prices. At December 31, 2016, the recorded fair value of our non-trading 
energy derivatives was a net asset of $38 million (before collateral), all of which is related to our Energy Services business segment.  
An increase of 10% in the market prices of energy commodities from their December 31, 2016 levels would have decreased the 
fair value of our non-trading energy derivatives net asset by $7 million. 

68

The above analysis of the non-trading energy derivatives utilized for commodity price risk management purposes does not 
include the favorable impact that the same hypothetical price movement would have on our non-derivative physical purchases 
and  sales  of  natural  gas  to  which  the  hedges  relate.  Furthermore,  the  non-trading  energy  derivative  portfolio  is  managed  to 
complement the physical transaction portfolio, reducing overall risks within limits. Therefore, the adverse impact to the fair value 
of the portfolio of non-trading energy derivatives held for hedging purposes associated with the hypothetical changes in commodity 
prices referenced above is expected to be substantially offset by a favorable impact on the underlying hedged physical transactions.

Item 8.        Financial Statements and Supplementary Data

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders of
CenterPoint Energy, Inc.
Houston, Texas

We have audited the accompanying consolidated balance sheets of CenterPoint Energy, Inc. and subsidiaries (the “Company”) 
as of December 31, 2016 and 2015, and the related statements of consolidated income, comprehensive income, shareholders’ 
equity, and cash flows for each of the three years in 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 audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States).  
Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements 
are free of material misstatement.  An audit includes examining, on a test basis, evidence supporting the amounts and disclosures 
in the financial statements.  An audit also includes assessing the accounting principles used and significant estimates made by 
management, as well as evaluating the overall financial statement presentation.  We believe that our audits provide a reasonable 
basis for our opinion.

CENTERPOINT ENERGY, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(1)          Background 

CenterPoint Energy, Inc. is a public utility holding company. CenterPoint Energy’s operating subsidiaries own and operate 
electric  transmission  and  distribution  and  natural  gas  distribution  facilities,  supply  natural  gas  to  commercial  and  industrial 
customers and electric and natural gas utilities and own interests in Enable as described below. CenterPoint Energy’s indirect, 
wholly-owned subsidiaries include:

•  Houston Electric, which engages in the electric transmission and distribution business in the Texas Gulf Coast area that 

includes the city of Houston; 

•  CERC Corp., which owns and operates natural gas distribution systems in six states; and

•  CES, which obtains and offers competitive variable and fixed-price physical natural gas supplies and services primarily 

to commercial and industrial customers and electric and natural gas utilities in 31 states. 

As of December 31, 2016, CenterPoint Energy also owned an aggregate of 14,520,000 Series A Preferred Units in Enable, 
which owns, operates and develops natural gas and crude oil infrastructure assets, and CERC Corp. owned approximately 54.1%
of the limited partner interests in Enable.

For a description of CenterPoint Energy’s reportable business segments, see Note 18.

(2)          Summary of Significant Accounting Policies  

(a) Use of Estimates

The preparation of financial statements in conformity with generally accepted accounting principles requires management to 
make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and 
liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. 
Actual results could differ from those estimates.

(b) Principles of Consolidation

The accounts of CenterPoint Energy and its wholly-owned and majority owned subsidiaries are included in the consolidated 
financial statements. All intercompany transactions and balances are eliminated in consolidation. CenterPoint Energy generally 
uses the equity method of accounting for investments in entities in which CenterPoint Energy has an ownership interest between 
20% and 50% and exercises significant influence. CenterPoint Energy also uses the equity method for investments in which it has 
ownership percentages greater than 50%, when it exercises significant influence, does not have control and is not considered the 
primary beneficiary, if applicable. 

In 2013, CenterPoint Energy, OGE and affiliates of ArcLight, formed Enable as a private limited partnership. CenterPoint 
Energy  has  the  ability  to  significantly  influence  the  operating  and  financial  policies  of,  but  not  solely  control,  Enable  and, 
accordingly, recorded an equity method investment, at the historical costs of net assets contributed.

Under the equity method, CenterPoint Energy adjusts its investment in Enable each period for contributions made, distributions 
received, CenterPoint Energy’s share of Enable’s comprehensive income and amortization of basis differences, as appropriate.  
CenterPoint Energy evaluates its equity method investments for impairment when events or changes in circumstances indicate 
there is a loss in value of the investment that is other than a temporary decline.  

CenterPoint Energy’s investment in Enable is considered to be a VIE because the power to direct the activities that most 
significantly impact Enable’s economic performance does not reside with the holders of equity investment at risk.  However, 
CenterPoint Energy is not considered the primary beneficiary of Enable since it does not have the power to direct the activities of 
Enable that are considered most significant to the economic performance of Enable.  

Other investments, excluding marketable securities, are carried at cost.  

78

As  of  December 31,  2016,  CenterPoint  Energy  had VIEs  consisting  of  the  Bond  Companies,  which  it  consolidates. The 
consolidated VIEs are wholly-owned, bankruptcy remote special purpose entities that were formed specifically for the purpose 
of securitizing transition and system restoration related property. Creditors of CenterPoint Energy have no recourse to any assets 
or revenues of the Bond Companies. The bonds issued by these VIEs are payable only from and secured by transition and system 
restoration property and the bondholders have no recourse to the general credit of CenterPoint Energy.

(c) Revenues

CenterPoint Energy records revenue for electricity delivery and natural gas sales and services under the accrual method and 
these revenues are recognized upon delivery to customers. Electricity deliveries not billed by month-end are accrued based on 
actual AMS data, daily supply volumes and applicable rates. Natural gas sales not billed by month-end are accrued based upon 
estimated purchased gas volumes, estimated lost and unaccounted for gas and currently effective tariff rates. 

(d) Long-lived Assets and Intangibles

CenterPoint  Energy  records  property,  plant  and  equipment  at  historical  cost.  CenterPoint  Energy  expenses  repair  and 

maintenance costs as incurred.

CenterPoint  Energy  periodically  evaluates  long-lived  assets,  including  property,  plant  and  equipment,  and  specifically 
identifiable intangibles, when events or changes in circumstances indicate that the carrying value of these assets may not be 
recoverable. The  determination  of  whether  an  impairment  has  occurred  is  based  on  an  estimate  of  undiscounted  cash  flows 
attributable to the assets compared to the carrying value of the assets.

(e) Regulatory Assets and Liabilities

CenterPoint Energy applies the guidance for accounting for regulated operations to the Electric Transmission & Distribution 
business segment and the Natural Gas Distribution business segment.  CenterPoint Energy’s rate-regulated subsidiaries may collect 
revenues subject to refund pending final determination in rate proceedings. In connection with such revenues, estimated rate refund 
liabilities are recorded which reflect management’s current judgment of the ultimate outcomes of the proceedings. 

CenterPoint  Energy  had  current  regulatory  assets  of  $70  million  and  $21  million  as  of  December  31,  2016  and  2015, 
respectively,  included  in  other  current  assets  in  its  Consolidated  Balance  Sheets.    CenterPoint  Energy  had  current  regulatory 
liabilities of $18 million and $57 million as of December 31, 2016 and 2015, respectively, included in other current liabilities in 
its Consolidated Balance Sheets.

CenterPoint Energy’s rate-regulated businesses recognize removal costs as a component of depreciation expense in accordance 
with regulatory treatment. As of December 31, 2016 and 2015, these removal costs of  $1,010 million and $980 million, respectively, 
are classified as regulatory liabilities in CenterPoint Energy’s Consolidated Balance Sheets. In addition, a portion of the amount 
of removal costs that relate to AROs has been reclassified from a regulatory liability to an asset retirement liability in accordance 
with accounting guidance for AROs.

(f) Depreciation and Amortization Expense

Depreciation and amortization is computed using the straight-line method based on economic lives or regulatory-mandated 

recovery periods. Amortization expense includes amortization of regulatory assets and other intangibles.

(g) Capitalization of Interest and AFUDC

Interest and AFUDC are capitalized as a component of projects under construction and are amortized over the assets’ estimated 
useful lives once the assets are placed in service. AFUDC represents the composite interest cost of borrowed funds and a reasonable 
return on the equity funds used for construction for subsidiaries that apply the guidance for accounting for regulated operations. 
Although AFUDC increases both utility plant and earnings, it is realized in cash when the assets are included in rates.  During 
2016, 2015 and 2014, CenterPoint Energy capitalized interest and AFUDC of $8 million, $10 million and $11 million, respectively.  
During 2016, 2015 and 2014, CenterPoint Energy recorded AFUDC equity of $7 million, $12 million and $14 million, respectively, 
which is included in Other Income in its Statements of Consolidated Income.

79

(h) Income Taxes

CenterPoint Energy uses the asset and liability method of accounting for deferred income taxes. Deferred income tax assets 
and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying 
amounts of existing assets and liabilities and their respective tax bases. A valuation allowance is established against deferred tax 
assets for which management believes realization is not considered to be more likely than not. CenterPoint Energy recognizes 
interest and penalties as a component of income tax expense.  CenterPoint Energy reports the income tax provision associated 
with its interest in Enable in Income tax expense (benefit) in its Statements of Consolidated Income.

(i) Accounts Receivable and Allowance for Doubtful Accounts

Accounts receivable are recorded at the invoiced amount and do not bear interest.  It is the policy of management to review 
the outstanding accounts receivable monthly, as well as the bad debt write-offs experienced in the past, and establish an allowance 
for doubtful accounts.  Account balances are charged off against the allowance when management determines it is probable the 
receivable will not be recovered.  The provision for doubtful accounts in CenterPoint Energy’s Statements of Consolidated Income 
for 2016, 2015 and 2014 was $7 million, $19 million and $22 million, respectively.

(j) Inventory

Inventory consists principally of materials and supplies and natural gas. Materials and supplies are valued at the lower of 
average cost or market.  Materials and supplies are recorded to inventory when purchased and subsequently charged to expense 
or capitalized to plant when installed. Natural gas inventories of CenterPoint Energy’s Energy Services business segment are 
valued at the lower of average cost or market. Natural gas inventories of CenterPoint Energy’s Natural Gas Distribution business 
segment are primarily valued at weighted average cost. During 2016, 2015 and 2014, CenterPoint Energy recorded $1 million, 
$4 million and $8 million, respectively, in write-downs of natural gas inventory to the lower of average cost or market.

(k) Derivative Instruments

CenterPoint Energy is exposed to various market risks. These risks arise from transactions entered into in the normal course 
of business.  CenterPoint Energy utilizes derivative instruments such as physical forward contracts, swaps and options to mitigate 
the impact of changes in commodity prices, weather and interest rates on its operating results and cash flows. Such derivatives 
are recognized in CenterPoint Energy’s Consolidated Balance Sheets at their fair value unless CenterPoint Energy elects the normal 
purchase and sales exemption for qualified physical transactions. A derivative may be designated as a normal purchase or normal 
sale if the intent is to physically receive or deliver the product for use or sale in the normal course of business.

CenterPoint Energy has a Risk Oversight Committee composed of corporate and business segment officers that oversees 
commodity price, weather and credit risk activities, including CenterPoint Energy’s marketing, risk management services and 
hedging activities. The committee’s duties are to establish CenterPoint Energy’s commodity risk policies, allocate board-approved 
commercial  risk  limits,  approve  the  use  of  new  products  and  commodities,  monitor  positions  and  ensure  compliance  with 
CenterPoint Energy’s risk management policies and procedures and limits established by CenterPoint Energy’s board of directors.

CenterPoint Energy’s policies prohibit the use of leveraged financial instruments. A leveraged financial instrument, for this 
purpose, is a transaction involving a derivative whose financial impact will be based on an amount other than the notional amount 
or volume of the instrument.

(l) Investments in Other Debt and Equity Securities

CenterPoint Energy reports securities classified as trading at estimated fair value in its Consolidated Balance Sheets, and any 

unrealized holding gains and losses are recorded as other income (expense) in its Statements of Consolidated Income.

(m) Environmental Costs

CenterPoint Energy expenses or capitalizes environmental expenditures, as appropriate, depending on their future economic 
benefit. CenterPoint Energy expenses amounts that relate to an existing condition caused by past operations that do not have future 
economic benefit. CenterPoint Energy records undiscounted liabilities related to these future costs when environmental assessments 
and/or remediation activities are probable and the costs can be reasonably estimated.

80

(n) Statements of Consolidated Cash Flows

For  purposes  of  reporting  cash  flows,  CenterPoint  Energy  considers  cash  equivalents  to  be  short-term,  highly-liquid 
investments with maturities of three months or less from the date of purchase. In connection with the issuance of securitization 
bonds, CenterPoint Energy was required to establish restricted cash accounts to collateralize the bonds that were issued in these 
financing transactions. These restricted cash accounts are not available for withdrawal until the maturity of the bonds and are not 
included in cash and cash equivalents. These restricted cash accounts of $40 million and $35 million as of December 31, 2016
and 2015, respectively, are included in other current assets in CenterPoint Energy’s Consolidated Balance Sheets.  Cash and cash 
equivalents included $340 million and $264 million as of December 31, 2016 and 2015, respectively, that was held by the Bond 
Companies solely to support servicing the securitization bonds.

CenterPoint Energy considers distributions received from equity method investments which do not exceed cumulative equity 
in earnings subsequent to the date of investment to be a return on investment and classifies these distributions as operating activities 
in the Statements of Consolidated Cash Flows. CenterPoint Energy considers distributions received from equity method investments 
in excess of cumulative equity in earnings subsequent to the date of investment to be a return of investment and classifies these 
distributions as investing activities in the Statements of Consolidated Cash Flows.

(o) New Accounting Pronouncements

In February 2015, the FASB issued ASU No. 2015-02, Consolidation (Topic 810): Amendments to the Consolidation Analysis
(ASU 2015-02). ASU 2015-02 changes the analysis that reporting organizations must perform to evaluate whether they should 
consolidate certain legal entities, such as limited partnerships. The changes include, among others, modification of the evaluation 
of whether limited partnerships and similar legal entities are VIEs or voting interest entities and elimination of the presumption 
that  a  general  partner  should  consolidate  a  limited  partnership. ASU  2015-02  does  not  amend  the  related  party  guidance  for 
situations in which power is shared between two or more entities that hold interests in a VIE. CenterPoint Energy adopted ASU 
2015-02 on January 1, 2016, which did not have a material impact on its financial position, results of operations, cash flows and 
disclosures.

In April  2015,  the  FASB  issued ASU  No.  2015-03,  Interest-Imputation  of  Interest  (Subtopic  835-30):  Simplifying  the 
Presentation of Debt Issuance Cost (ASU 2015-03).  ASU 2015-03 requires that debt issuance costs related to a recognized debt 
liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt 
discounts. The recognition and measurement guidance for debt issuance costs are not affected by ASU 2015-03. CenterPoint 
Energy adopted ASU 2015-03 retrospectively on January 1, 2016, which resulted in a reduction of other long-term assets, indexed 
debt and total long-term debt on its Consolidated Balance Sheets. CenterPoint Energy had debt issuance costs, excluding amounts 
related to credit facility arrangements, of $42 million and $44 million as a reduction to long-term debt on its Consolidated Balance 
Sheets as of December 31, 2016 and 2015, respectively. 

In May 2015, the FASB issued ASU No. 2015-07, Fair Value Measurement (Topic 820): Disclosures for Investments in Certain 
Entities That Calculate Net Asset Value per Share (or Its Equivalent) (ASU 2015-07). ASU 2015-07 removes the requirement to 
categorize within the fair value hierarchy investments for which fair values are measured at NAV using the practical expedient. 
Entities will be required to disclose the fair value of investments measured using the NAV practical expedient so that financial 
statement users can reconcile amounts reported in the fair value hierarchy table to amounts reported on the balance sheet. CenterPoint 
Energy retrospectively adopted ASU 2015-07 on January 1, 2016, which impacts its employee benefit plan disclosures. See Note 
7 for the impacts on the employee benefit plan disclosures. This standard did not have an impact on CenterPoint Energy’s financial 
position, results of operations or cash flows.

In September 2015, the FASB issued ASU No. 2015-16, Business Combinations (Topic 805): Simplifying the Accounting for 
Measurement-Period  Adjustments  (ASU  2015-16).   ASU  2015-16  eliminates  the  requirement  for  an  acquirer  in  a  business 
combination to account for measurement-period adjustments retrospectively. Instead, an acquirer would recognize a measurement-
period adjustment during the period in which the amount of the adjustment is determined. CenterPoint Energy prospectively 
adopted ASU 2015-16 on January 1, 2016, which did not have an impact on its financial position, results of operations or cash 
flows.

In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments-Overall (Subtopic 825-10): Recognition and 
Measurement of Financial Assets and Financial Liabilities (ASU 2016-01). ASU 2016-01 requires equity investments that do not 
result in consolidation and are not accounted for under the equity method to be measured at fair value and to recognize any changes 
in fair value in net income unless the investments qualify for the new practicability exception. It does not change the guidance for 
classifying and measuring investments in debt securities and loans. ASU 2016-01 also changes certain disclosure requirements 
81

and other aspects related to recognition and measurement of financial assets and financial liabilities. ASU 2016-01 is effective for 
fiscal years, and interim periods within those years, beginning after December 15, 2017. As of the first reporting period in which 
the guidance is adopted, a cumulative-effect adjustment to beginning retained earnings will be made, with two features that will 
be adopted prospectively. CenterPoint Energy is currently assessing the impact that this standard will have on its financial position, 
results of operations, cash flows and disclosures.

In  February  2016,  the  FASB  issued ASU  No.  2016-02,  Leases  (Topic  842)  (ASU  2016-02). ASU  2016-02  provides  a 
comprehensive new lease model that requires lessees to recognize assets and liabilities for most leases and would change certain 
aspects of lessor accounting. ASU 2016-02 is effective for fiscal years, and interim periods within those fiscal years, beginning 
after December 15, 2018, with early adoption permitted. A modified retrospective adoption approach is required. CenterPoint 
Energy is currently assessing the impact that this standard will have on its financial position, results of operations, cash flows and 
disclosures.

In 2016, the FASB issued ASUs which amended ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606). 
ASU 2014-09, as amended, provides a comprehensive new revenue recognition model that requires revenue to be recognized in 
a manner that depicts the transfer of goods or services to a customer at an amount that reflects the consideration expected to be 
received in exchange for those goods or services. Early adoption is not permitted, and entities have the option of using either a 
full retrospective or a modified retrospective adoption approach. CenterPoint Energy is currently evaluating its revenue streams 
under these ASUs and has not yet identified any significant changes as the result of these new standards. A substantial amount of 
CenterPoint  Energy’s  revenues  are  tariff  based,  which  we  do  not  anticipate  will  be  significantly  impacted  by  these ASUs. 
CenterPoint Energy is considering the impacts of the new guidance on its ability to recognize revenue for certain contracts when 
collectability is uncertain and its accounting for contributions in aid of construction. CenterPoint Energy expects to adopt these 
ASUs on January 1, 2018 and is evaluating the method of adoption.

In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash 
Receipts and Cash Payments (ASU 2016-15). ASU 2016-15 provides clarifying guidance on the classification of certain cash 
receipts and payments in the statement of cash flows and eliminates the variation in practice related to such classifications. ASU 
2016-15 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017, with early 
adoption permitted. A retrospective adoption approach is required. CenterPoint Energy is currently assessing the impact that this 
standard will have on its statement of cash flows.

In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash (ASU 2016-18). 
ASU 2016-18 requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, 
restricted cash and restricted cash equivalents. As a result, the statement of cash flows will no longer present transfers between 
cash and cash equivalents and restricted cash and restricted cash equivalents. When cash, cash equivalents, restricted cash and 
restricted cash equivalents are presented in more than one line item on the balance sheet, the new guidance requires a reconciliation 
of the totals in the statement of cash flows to the related captions in the balance sheet. ASU 2016-18 is effective for fiscal years, 
and interim periods within those fiscal years, beginning after December 15, 2017, with early adoption permitted. A retrospective 
adoption approach is required. CenterPoint Energy is currently assessing the impact that this standard will have on its statement 
of cash flows and disclosures. 

In January 2017, the FASB issued ASU No. 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a 
Business (ASU 2017-01). ASU 2017-01 revises the definition of a business. If substantially all of the fair value of the gross assets 
acquired is concentrated in a single identifiable asset or a group of similar identifiable assets, then under ASU 2017-01, the asset 
or group of assets is not a business. The guidance also requires a business to include at least one substantive process and narrows 
the definition of outputs to be more closely aligned with how outputs are described in ASC 606. ASU 2017-01 is effective for 
fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017, with early adoption permitted in 
certain circumstances. A prospective adoption approach is required. ASU 2017-01 could have a potential impact on CenterPoint 
Energy’s accounting for future acquisitions.

In January 2017, the FASB issued ASU No. 2017-04, Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for 
Goodwill  Impairment  (ASU  2017-04). ASU  2017-04  eliminates  Step  2  of  the  goodwill  impairment  test,  which  requires  a 
hypothetical purchase price allocation. A goodwill impairment will now be the amount by which a reporting unit’s carrying value 
exceeds its fair value, not to exceed the carrying amount of goodwill. ASU 2017-04 is effective for fiscal years, and interim periods 
within those fiscal years, beginning after December 15, 2019, with early adoption permitted. A prospective adoption approach is 
required. ASU 2017-04 will have an impact on CenterPoint Energy’s future calculation of goodwill impairments if an impairment 
is identified.

82

Management believes that other recently issued standards, which are not yet effective, will not have a material impact on 

CenterPoint Energy’s consolidated financial position, results of operations or cash flows upon adoption.

CenterPoint Energy recorded AROs associated with the removal of asbestos and asbestos-containing material in its buildings, 
including substation building structures. CenterPoint Energy also recorded AROs relating to gas pipelines abandoned in place, 
treated wood poles for electric distribution, distribution transformers containing PCB (also known as Polychlorinated Biphenyl), 
and underground fuel storage tanks. The estimates of future liabilities were developed using historical information, and where 
available, quoted prices from outside contractors.

83

 
 
 
 
 
 
The increase of $13 million in the ARO from the revision in estimates in 2015 is primarily attributable to an increase in 

estimated disposal costs. 

(4)          Acquisition 

On April 1,  2016, CES,  an  indirect,  wholly-owned  subsidiary  of  CenterPoint  Energy,  closed  the  previously  announced 
agreement to acquire the retail energy services business and natural gas wholesale assets of Continuum. After working capital 
adjustments, the final purchase price was $102 million and allocated to identifiable assets acquired and liabilities assumed based 
on their estimated fair values on the acquisition date.

The  following  table  summarizes  the  final  purchase  price  allocation  and  the  fair  value  amounts  recognized  for  the  assets 

acquired and liabilities assumed related to the acquisition:

The goodwill of $22 million resulting from the acquisition reflects the excess of the purchase price over the fair value of the 
net identifiable assets acquired. The goodwill recorded as part of the acquisition primarily reflects the value of the complementary 
operational and geographic footprints, along with the scale, geographic reach and expanded capabilities.

Identifiable  intangible  assets  were  recorded  at  estimated  fair  value  as  determined  by  management  based  on  available 
information, which includes a valuation prepared by an independent third party. The significant assumptions used in arriving at 
the estimated identifiable intangible asset values included management’s estimates of future cash flows, the discount rate which 
is based on the weighted average cost of capital for comparable publicly traded guideline companies and projected customer 
attrition rates. The useful lives for the identifiable intangible assets were determined using methods that approximate the pattern 
of economic benefit provided by the utilization of the assets.

allocation include:

Amortization expense related to the above identifiable intangible assets was $3 million for the year ended December 31, 2016.

Revenues of approximately $466 million and operating income of approximately $1 million attributable to the acquisition 

are included in CenterPoint Energy’s Statements of Consolidated Income for the year ended December 31, 2016.  

84

As Continuum was a non-public company that did not prepare interim financial information and the acquisition included the 
purchase of both businesses and assets, the historical financial information for the businesses and assets acquired was impracticable 
to obtain. As a result, pro forma results of the acquired businesses and assets are not presented.

(2) Amount presented is net of the accumulated goodwill impairment charge of $252 million.

CenterPoint Energy performs goodwill impairment tests at least annually and evaluates goodwill when events or changes in 
circumstances indicate that its carrying value may not be recoverable. The impairment evaluation for goodwill is performed by 
using a two-step process. In the first step, the fair value of each reporting unit is compared with the carrying amount of the reporting 
unit, including goodwill. The estimated fair value of the reporting unit is generally determined on the basis of discounted cash 
flows. If the estimated fair value of the reporting unit is less than the carrying amount of the reporting unit, then a second step 
must be completed to determine the amount of the goodwill impairment that should be recorded. In the second step, the implied 
fair value of the reporting unit’s goodwill is determined by allocating the reporting unit’s fair value to all of its assets and liabilities 
other than goodwill (including any unrecognized intangible assets) in a manner similar to a purchase price allocation. The resulting 
implied fair value of the goodwill that results from the application of this second step is then compared to the carrying amount of 
the goodwill and an impairment charge is recorded for the difference.

CenterPoint Energy performed its annual goodwill impairment test in the third quarter of each of  2016 and 2015 and determined, 
based on the results of the first step, that no goodwill impairment charge was required for any reportable segment.  Other intangibles 
were not material as of December 31, 2016 and 2015.

(1)  The unrecognized allowed equity return will be recognized as it is recovered in rates through 2024. During the years 
ended December 31, 2016, 2015 and 2014, Houston Electric recognized approximately $64 million, $49 million and $68 
million, respectively, of the allowed equity return. The timing of CenterPoint Energy’s recognition of the allowed equity 
return will vary each period based on amounts actually collected during the period. The actual amounts recovered for the 
allowed equity return are reviewed and adjusted at least annually by the PUCT to correct any over-collections or under-
collections during the preceding 12 months and to provide for the full and timely recovery of the allowed equity return.  

(2)  NGD’s  actuarially  determined  pension  and  other  postemployment  expense  in  excess  of  the  amount  being  recovered 
through rates is being deferred for rate making purposes. Deferred pension and other postemployment expenses of $6 
million and $5 million as of December 31, 2016 and 2015, respectively, were not earning a return. 

(3)  Other regulatory assets that are not earning a return were not material as of December 31, 2016 and 2015. 

(7)          Stock-Based Incentive Compensation Plans and Employee Benefit Plans 

(a) Stock-Based Incentive Compensation Plans 

CenterPoint Energy has LTIPs that provide for the issuance of stock-based incentives, including stock options, performance 
awards, restricted stock unit awards and restricted and unrestricted stock awards to officers, employees and non-employee directors.  
Approximately 14 million shares of CenterPoint Energy common stock are authorized under these plans for awards.

Equity awards are granted to employees without cost to the participants. The performance awards granted in 2016, 2015 and 
2014 are distributed based upon the achievement of certain objectives over a three-year performance cycle. The stock awards 
granted in 2016, 2015 and 2014 are service based.  The stock awards generally vest at the end of a three-year period. Upon vesting, 
both the performance and stock awards are issued to the participants along with the value of dividend equivalents earned over the 
performance cycle or vesting period. CenterPoint Energy issues new shares to satisfy stock-based payments related to LTIPs.

CenterPoint Energy recorded LTIP compensation expense of $19 million, $17 million and $18 million for the years ended 
December 31,  2016,  2015  and  2014,  respectively.  This  expense  is  included  in  Operation  and  Maintenance  Expense  in  the 
Statements of Consolidated Income.

The  total  income  tax  benefit  recognized  related  to  LTIPs  was  $7  million,  $6  million  and  $7  million  for  the  years  ended 
December 31, 2016, 2015 and 2014, respectively.  No compensation cost related to LTIPs was capitalized as a part of inventory 
or fixed assets in 2016, 2015 or 2014. The actual tax benefit realized for tax deductions related to LTIPs totaled $5 million, $6 
million and $13 million for 2016, 2015 and 2014, respectively.

86

Compensation costs for the performance and stock awards granted under LTIPs are measured using fair value and expected 
achievement levels on the grant date.  For performance awards with operational goals, the achievement levels are revised as goals 
are evaluated.  The fair value of awards granted to employees is based on the closing stock price of CenterPoint Energy’s common 
stock on the grant date.  The compensation expense is recorded on a straight-line basis over the vesting period.  Forfeitures are 
estimated on the date of grant based on historical averages, and estimates are updated periodically throughout the vesting period.  

The following tables summarize CenterPoint Energy’s LTIP activity for 2016:  

Stock Options

CenterPoint Energy has not issued stock options since 2004.  There were no outstanding stock options at either December 

31, 2016 or 2015.

Cash received from stock options exercised was $1 million for 2014.

The total grant date fair value of performance and stock awards which vested during the years ended December 31, 2016, 
2015 and 2014 was $13 million, $13 million and $21 million, respectively.  As of December 31, 2016, there was $21 million of 
total unrecognized compensation cost related to non-vested performance and stock awards which is expected to be recognized 
over a weighted-average period of 1.7 years.

(b) Pension and Postretirement Benefits

CenterPoint Energy maintains a non-contributory qualified defined benefit pension plan covering substantially all employees, 
with benefits determined using a cash balance formula. Under the cash balance formula, participants accumulate a retirement 
benefit based upon 5% of eligible earnings and accrued interest. Participants are 100% vested in their benefit after completing 
three years  of service. In addition to the non-contributory qualified defined benefit pension plan, CenterPoint Energy maintains 
unfunded non-qualified benefit restoration plans which allow participants to receive the benefits to which they would have been 
entitled under CenterPoint Energy’s non-contributory pension plan except for federally mandated limits on qualified plan benefits 
or on the level of compensation on which qualified plan benefits may be calculated.

CenterPoint Energy provides certain healthcare and life insurance benefits for retired employees on both a contributory and 
non-contributory basis. Employees become eligible for these benefits if they have met certain age and service requirements at 
retirement, as defined in the plans. Such benefit costs are accrued over the active service period of employees. The net unrecognized 
transition obligation is being amortized over approximately 20 years. Effective January 1, 2017, members of the IBEW Local 
Union 66 who retire on or after January 1, 2017, and their dependents, will receive any retiree medical and prescription drug 
benefits exclusively through the NECA/IBEW Family Medical Care Plan pursuant to the terms of the renegotiated collective 
bargaining agreement entered into in May 2016.   

CenterPoint Energy’s net periodic cost includes the following components relating to pension, including the benefit restoration 

plan, and postretirement benefits:

(1)  A curtailment gain or loss is required when the expected future services of a significant number of current employees are 
reduced or eliminated for the accrual of benefits. During the fourth quarter of 2014, CenterPoint Energy recognized a 
curtailment  pension  loss  of  $6  million  related  to  employees  seconded  to  Enable.  Substantially  all  of  the  seconded 
employees became employees of Enable effective January 1, 2015. Also, postretirement healthcare benefits were amended 
during 2016 resulting in a net curtailment gain of $5 million.  In May 2016, Houston Electric entered into a renegotiated 

88

 
collective bargaining agreement with the IBEW Local Union 66 that provides that for Houston Electric union employees 
covered under the agreement who retire on or after January 1, 2017, retiree medical and prescription drug coverage will 
be provided exclusively through the NECA/IBEW Family Medical Care Plan in exchange for the payment of monthly 
premiums as determined under the agreement.  As a result, the accrued postretirement benefits related to such future 
Houston Electric union retirees were eliminated. Houston Electric recognized a curtailment gain of $3 million as an 
accelerated recognition of the prior service credit that would otherwise be recognized in future periods for the post-
retirement plan. CenterPoint Energy also recognized an additional curtailment gain of $2 million in October 2016 related 
to other amendments in the post-retirement plan. As a result of these amendments, the 2016 post-retirement expense was 
significantly lower than expenses reported for previous years.

(2)  A one-time, non-cash settlement charge is required when lump sum distributions or other settlements of plan benefit 
obligations during a plan year exceed the service cost and interest cost components of net periodic cost for that year.  Due 
to the amount of lump sum payment distributions from the non-qualified pension plan during the year ended December 
31, 2015, CenterPoint Energy recognized a non-cash settlement charge of $10 million.  This charge is an acceleration of 
costs that would otherwise be recognized in future periods.  

CenterPoint Energy used the following assumptions to determine net periodic cost relating to pension and postretirement 

benefits:

(1)  The Postretirement plan was amended during 2016 to change retiree medical coverage, effective January 1, 2017, as 
follows: (i) members of the IBEW Local Union 66 who retire on or after January 1, 2017, and their dependents, will 
receive any retiree medical and prescription drug coverage exclusively through the NECA/IBEW Family Medical Care 
Plan pursuant to the terms of the renegotiated collective bargaining agreement entered into in May 2016; and (ii)  Medicare 
eligible post-65 retirees will receive coverage through a Medicare Advantage Program, an insured benefit, in lieu of the 
previous self-insured benefit.  These changes resulted in a reduction in our Postretirement Plan liability of $56 million
as of December 31, 2016.

(2)  In May 2016, Houston Electric entered into a renegotiated collective bargaining agreement with the IBEW Local Union 
66 and amended the Houston Electric Union Postretirement Trust.  The amendment resulted in a split of the trust into 
two segregated and restricted accounts, one holds assets for the benefit of current, retired on or before December 31, 
2016, union retirees and one holds assets for the benefit of post-2016 union retirees who are now covered exclusively by 
the NECA/IBEW Family Medical Care Plan. Accordingly, $20 million was transferred to the account for post-2016 union 
retirees.

The  accumulated  benefit  obligation  for  all  defined  benefit  pension  plans  was  $2,168  million  and  $2,157  million  as  of 

December 31, 2016 and 2015, respectively.

The expected rate of return assumption was developed using the targeted asset allocation of CenterPoint Energy’s plans and 

the expected return for each asset class.

The discount rate assumption was determined by matching the projected cash flows of CenterPoint Energy’s plans against a 
hypothetical yield curve of high-quality corporate bonds represented by a series of annualized individual discount rates from one-
half to 99 years. 

For measurement purposes, medical costs are assumed to increase to 5.75%  and 10.65% for the pre-65 and post-65 retirees 
during 2017, respectively, and the prescription cost is assumed to increase to 10.75% during 2017, after which these rates decrease 
until reaching the ultimate trend rate of 4.50% in 2024.

CenterPoint  Energy’s  changes  in  accumulated  comprehensive  loss  related  to  defined  benefit,  postretirement  and  other 

postemployment plans are as follows:

In managing the investments associated with the benefit plans, CenterPoint Energy’s objective is to achieve and maintain a 
fully funded plan.  This objective is expected to be achieved through an investment strategy that manages liquidity requirements 
while maintaining a long-term horizon in making investment decisions and efficient and effective management of plan assets.

CenterPoint Energy has a tax-qualified employee savings plan that includes a cash or deferred arrangement under Section 401
(k) of the Internal Revenue Code of 1986, as amended (the Code), and an employee stock ownership plan under Section 4975(e)
(7) of the Code. Under the plan, participating employees may contribute a portion of their compensation, on a pre-tax or after-tax 
basis, generally up to a maximum of 50% of eligible compensation. CenterPoint Energy matches 100% of the first 6% of each 
employee’s compensation contributed. The matching contributions are fully vested at all times.

Participating employees may elect to invest all (prior to January 1, 2016) or a portion of their contributions to the plan in 
CenterPoint Energy, Inc. common stock, to have dividends reinvested in additional shares or to receive dividend payments in cash 
on any investment in CenterPoint Energy, Inc. common stock, and to transfer all or part of their investment in CenterPoint Energy, 
Inc. common stock to other investment options offered by the plan.

Effective January 1, 2016, the savings plan was amended to limit the percentage of future contributions that could be invested 
in CenterPoint Energy, Inc. common stock to 25% and to prohibit transfers of account balances where the transfer would result 
in more than 25% of a participant’s total account balance invested in CenterPoint Energy, Inc. common stock.

The savings plan has significant holdings of CenterPoint Energy, Inc. common stock. As of December 31, 2016, 14,216,986
shares of CenterPoint Energy, Inc. common stock were held by the savings plan, which represented approximately 17% of its 
investments. Given the concentration of the investments in CenterPoint Energy, Inc. common stock, the savings plan and its 
participants have market risk related to this investment.

CenterPoint Energy’s savings plan benefit expenses were $38 million, $35 million and $39 million in 2016, 2015 and 2014, 

respectively.

95

(d) Postemployment Benefits

CenterPoint Energy provides postemployment benefits for certain former or inactive employees, their beneficiaries and covered 
dependents, after employment but before retirement (primarily healthcare and life insurance benefits for participants in the long-
term disability plan). CenterPoint Energy recorded postemployment expenses of $5 million, $2 million and $3 million in 2016, 
2015 and 2014, respectively.

Included in Benefit Obligations in the accompanying Consolidated Balance Sheets as of December 31, 2016 and 2015 was 

$22 million and $23 million, respectively, relating to postemployment obligations.

(e) Other Non-Qualified Plans

CenterPoint Energy has non-qualified deferred compensation plans that provide benefits payable to directors, officers and 
certain key employees or their designated beneficiaries at specified future dates or upon termination, retirement or death. Benefit 
payments are made from the general assets of CenterPoint Energy. CenterPoint Energy recorded benefit expense relating to these 
plans of $3 million, $3 million and $5 million for the years in 2016, 2015 and 2014, respectively.  Included in Benefit Obligations 
in the accompanying Consolidated Balance Sheets as of December 31, 2016 and 2015 was $47 million and $51 million, respectively, 
relating to deferred compensation plans.

Included in Benefit Obligations in CenterPoint Energy’s Consolidated Balance Sheets as of December 31, 2016 and 2015

was $40 million and $32 million, respectively, relating to split-dollar life insurance arrangements.

(f) Change in Control Agreements and Other Employee Matters

CenterPoint Energy had change in control agreements with certain of its officers, which expired December 31, 2014.  In lieu 
of these agreements, our Board of Directors approved a new change in control plan, which was effective January 1, 2015.  The 
plan, like the expired agreements, generally provides, to the extent applicable, in the case of a change in control of CenterPoint 
Energy and termination of employment, for severance benefits of up to three times annual base salary plus bonus, and other 
benefits.  Our officers, including our Executive Chairman, are participants under the plan.

As of December 31, 2016, approximately 35% of CenterPoint Energy’s employees were covered by collective bargaining 
agreements. The collective bargaining agreement with the IBEW Local 66 and the two collective bargaining agreements with 
Professional  Employees  International  Union  Local  12,  which  collectively  cover  approximately  21%  of  CenterPoint  Energy’s 
employees,  expired  in  March  and  May  of  2016,  respectively.  CenterPoint  Energy  successfully  negotiated  all  three  follow-on 
agreements in 2016. The new collective bargaining agreement with the IBEW Local 66 expires in May of 2020, and the two new 
collective bargaining agreements with Professional Employees International Union Local 12 expire in March and May of 2021, 
respectively. 

The collective bargaining agreements with Gas Workers Union, Local 340 and the IBEW, Local 949, covering approximately 
8% of CenterPoint Energy’s employees, will expire in April and December of 2020, respectively. These two agreements were last 
negotiated in 2015. 

The  two  collective  bargaining  agreements  with  the  United  Steelworkers  Union,  Locals  13-227  and  13-1,  which  cover 
approximately 6% of CenterPoint Energy’s employees, are scheduled to expire in June and July of 2017, respectively. CenterPoint 
Energy believes it has good relationships with these bargaining units and expect to negotiate new agreements in 2017.

(8)          Derivative Instruments 

CenterPoint Energy is exposed to various market risks. These risks arise from transactions entered into in the normal course 
of business.  CenterPoint Energy utilizes derivative instruments such as physical forward contracts, swaps and options to mitigate 
the impact of changes in commodity prices, weather and interest rates on its operating results and cash flows. 

(a) Non-Trading Activities

Derivative Instruments. CenterPoint Energy enters into certain derivative instruments to mitigate the effects of commodity 

price movements. These financial instruments do not qualify or are not designated as cash flow or fair value hedges.

Weather Hedges.  CenterPoint Energy has weather normalization or other rate mechanisms that mitigate the impact of weather 
on NGD in Arkansas, Louisiana, Mississippi, Minnesota and Oklahoma. NGD and electric operations in Texas do not have such 
96

mechanisms, although fixed customer charges are historically higher in Texas for NGD compared to CenterPoint Energy’s other 
jurisdictions.   As a result, fluctuations from normal weather may have a positive or negative effect on NGD’s results in Texas and 
on Houston Electric’s results in its service territory.

CenterPoint Energy has historically entered into heating-degree day swaps for certain NGD jurisdictions to mitigate the effect 
of fluctuations from normal weather on its results of operations and cash flows for the winter heating season, which contained a 
bilateral dollar cap of $16 million in 2014–2015.  However, NGD did not enter into heating-degree day swaps for the 2015–2016 
winter season as a result of NGD’s Minnesota division implementing a full decoupling pilot in July 2015. CenterPoint Energy  
entered into weather hedges for the Houston Electric service territory, which contained bilateral dollar caps of $8 million, $7 
million and $9 million for the 2014–2015, 2015–2016 and 2016–2017 winter seasons, respectively.  The swaps are based on 10-
year  normal  weather.  During  the  years  ended  December 31,  2016,  2015  and  2014,  CenterPoint  Energy  recognized  a  gain  of 
$1 million, and losses of $6 million and $11 million, respectively, related to these swaps.  Weather hedge gains and losses are 
included in revenues in the Statements of Consolidated Income.

Hedging of Interest Expense for Future Debt Issuances. In April 2016, Houston Electric entered into forward interest rate 
agreements with several counterparties, having an aggregate notional amount of $150 million. These agreements were executed 
to hedge, in part, volatility in the 5-year U.S. treasury rate by reducing Houston Electric’s exposure to variability in cash flows 
related to interest payments of Houston Electric’s $300 million issuance of fixed rate debt in May 2016. These forward interest 
rate agreements were designated as cash flow hedges. The realized gains and losses associated with the agreements were immaterial.

In June and July 2016, Houston Electric entered into forward interest rate agreements with several counterparties, having an 
aggregate notional amount of $300 million. These agreements were executed to hedge, in part, volatility in the 10-year U.S. treasury 
rate by reducing Houston Electric’s exposure to variability in cash flows related to interest payments of Houston Electric’s $300 
million issuance of fixed rate debt in August 2016.  These forward interest rate agreements were designated as cash flow hedges.  
Accordingly, the effective portion of realized gains associated with the agreements, which totaled $1.1 million, is a component of 
accumulated other comprehensive income and will be amortized over the life of the bonds.  The ineffective portion of the gains 
and losses was recorded in income and was immaterial.

In  January  2017,  Houston  Electric  entered  into  forward  interest  rate  agreements  with  several  counterparties,  having  an 
aggregate notional amount of $150 million. These agreements were executed to hedge, in part, volatility in the 10-year U.S. treasury 
rate by reducing Houston Electric’s exposure to variability in cash flows related to interest payments of Houston Electric’s $300 
million issuance of fixed rate debt in January 2017. These forward interest rate agreements were designated as cash flow hedges. 
Accordingly, the effective portion of unrealized losses associated with the agreements, which totaled approximately $0.5 million, 
will be a component of accumulated other comprehensive income in 2017 and will be amortized over the life of the bonds.

(c) Credit Risk Contingent Features

CenterPoint Energy enters into financial derivative contracts containing material adverse change provisions.  These provisions 
could require CenterPoint Energy to post additional collateral if the S&P or Moody’s credit ratings of CenterPoint Energy, Inc. or 
its subsidiaries are downgraded.  The total fair value of the derivative instruments that contain credit risk contingent features that 
are in a net liability position as of December 31, 2016 and 2015 was $1 million and $3 million, respectively.  CenterPoint Energy 
posted no assets as collateral towards derivative instruments that contain credit risk contingent features as of either December 31, 
2016 or 2015.  If all derivative contracts (in a net liability position) containing credit risk contingent features were triggered at 
December 31, 2016 and 2015, $-0- and $2 million, respectively, of additional assets would be required to be posted as collateral.

99

(d) Credit Quality of Counterparties

In addition to the risk  associated with price  movements, credit risk is also  inherent in CenterPoint  Energy’s  non-trading 
derivative  activities.  Credit  risk  relates  to  the  risk  of  loss  resulting  from  non-performance  of  contractual  obligations  by  a 
counterparty. The following table shows the composition of counterparties to the non-trading derivative assets of CenterPoint 
Energy as of December 31, 2016 and 2015:

(1)  “Investment grade” is primarily determined using publicly available credit ratings and considers credit support (including 
parent company guarantees) and collateral (including cash and standby letters of credit). For unrated counterparties, 
CenterPoint  Energy  determines  a  synthetic  credit  rating  by  performing  financial  statement  analysis  and  considers 
contractual rights and restrictions and collateral.

(2)  End users are comprised primarily of customers who have contracted to fix the price of a portion of their physical gas 

requirements for future periods.

(3)  The net of total non-trading natural gas derivative assets was $70 million and $125 million as of December 31, 2016 and 
2015, respectively, as shown on CenterPoint Energy’s Consolidated Balance Sheets, and was comprised of the natural 
gas contracts derivatives assets separately shown above, impacted by collateral netting of $14 million and $-0- as of 
December 31, 2016 and 2015, respectively.

(9)          Fair Value Measurements 

Assets and liabilities that are recorded at fair value in the Consolidated Balance Sheets are categorized based upon the level 
of judgment associated with the inputs used to measure their value. Hierarchical levels, as defined below and directly related to 
the amount of subjectivity associated with the inputs to fair valuations of these assets and liabilities, are as follows:

Level 1: Inputs are unadjusted quoted prices in active markets for identical assets or liabilities at the measurement date. The 
types of assets carried at Level 1 fair value generally are exchange-traded derivatives and equity securities.

Level 2: Inputs, other than quoted prices included in Level 1, are observable for the asset or liability, either directly or indirectly. 
Level 2 inputs include quoted prices for similar instruments in active markets, and inputs other than quoted prices that are 
observable for the asset or liability. Fair value assets and liabilities that are generally included in this category are derivatives 
with fair values based on inputs from actively quoted markets.  A market approach is utilized to value CenterPoint Energy’s 
Level 2 assets or liabilities.

Level 3: Inputs are unobservable for the asset or liability, and include situations where there is little, if any, market activity 
for the asset or liability.  Unobservable inputs reflect CenterPoint Energy’s judgments about the assumptions market participants 
would use in pricing the asset or liability since limited market data exists. CenterPoint Energy develops these inputs based 
on the best information available, including CenterPoint Energy’s own data. A market approach is utilized to value CenterPoint 
Energy’s Level 3 assets or liabilities. At December 31, 2016, CenterPoint Energy’s Level 3 assets and liabilities are comprised 
of physical forward contracts and options and its indexed debt securities derivative.  Level 3 physical forward contracts are 
valued using a discounted cash flow model which includes illiquid forward price curve locations (ranging from $2.24 to $7.01
per MMBtu) as an unobservable input. Level 3 options are valued through Black-Scholes (including forward start) option 
models which include option volatilities (ranging from 0% to 86%) as an unobservable input.  CenterPoint Energy’s Level 3 
physical forward contracts and options derivative assets and liabilities consist of both long and short positions (forwards and 
options) and their fair value is sensitive to forward prices and volatilities.  If forward prices decrease, CenterPoint Energy’s 
long forwards lose value whereas its short forwards gain in value.  If volatility decreases, CenterPoint Energy’s long options 
lose value whereas its short options gain in value. CenterPoint Energy’s Level 3 indexed debt securities are valued using a 
Black-Scholes option model and a discounted cash flow model, which use option volatility (19%) and a projected dividend 

100

growth rate (8%) as unobservable inputs. An increase in either volatilities or projected dividends will increase the value of 
the indexed debt securities, and a decrease in either volatilities or projected dividends will decrease the value of the indexed 
debt securities.                                               

CenterPoint Energy determines the appropriate level for each financial asset and liability on a quarterly basis and recognizes 
transfers between levels at the end of the reporting period.  For the year ended December 31, 2016, there were no transfers between 
Level 1 and 2.  CenterPoint Energy also recognizes purchases of Level 3 financial assets and liabilities at their fair market value 
at the end of the reporting period. 

The following tables present information about CenterPoint Energy’s assets and liabilities (including derivatives that are 
presented net) measured at fair value on a recurring basis, and indicate the fair value hierarchy of the valuation techniques utilized 
by CenterPoint Energy to determine such fair value.

(1)  During 2016, CenterPoint Energy transferred its indexed debt securities from Level 2 to Level 3 to reflect changes in the 
significance of the unobservable inputs used in the valuation.  As of December 31, 2016, the indexed debt securities 
liability was $717 million.  During 2016, there was a loss of $413 million on the indexed debt securities.

(2)  During 2016, 2015 and 2014, CenterPoint Energy did not have significant Level 3 sales.

Items Measured at Fair Value on a Nonrecurring Basis 

In 2015, CenterPoint Energy determined that an other than temporary decrease in the value of its investment in Enable had 
occurred and, using multiple valuation methodologies under both the market and income approaches, recorded an impairment on 
its  investment  in  Enable  of  $1,225  million.  Key  assumptions  in  the  market  approach  included  recent  market  transactions  of 
comparable companies and EBITDA to total enterprise multiples for comparable companies. Due to volatility of the quoted price 
of Enable’s units at the valuation date, a volume weighted average price was used under the market approach to best approximate 
fair value at the measurement date. Key assumptions in the income approach included Enable’s forecasted cash distributions, 
projected cash flows of incentive distribution rights, forecasted growth rate of Enable’s cash distributions beyond 2020, and the 
discount rate used to determine the present value of the estimated future cash flows. A weighing of the different approaches was 
utilized to determine the estimated fair value of our investment in Enable. Based on the significant unobservable estimates and 
assumptions required, CenterPoint Energy concluded that the fair value estimate should be classified as a Level 3 measurement 
within the fair value hierarchy. See Note 10 for further discussion of the impairments. As of December 31, 2016, there were no 
significant assets or liabilities measured at fair value on a nonrecurring basis.

Estimated Fair Value of Financial Instruments

The fair values of cash and cash equivalents, investments in debt and equity securities classified as “trading” and short-term 
borrowings are estimated to be approximately equivalent to carrying amounts and have been excluded from the table below. The 
carrying amounts of non-trading derivative assets and liabilities and CenterPoint Energy’s ZENS indexed debt securities derivative 
are stated at fair value and are excluded from the table below.  The fair value of each debt instrument is determined by multiplying 
the principal amount of each debt instrument by the market price.  These assets and liabilities, which are not measured at fair value 
in the Consolidated Balance Sheets but for which the fair value is disclosed, would be classified as Level 1 or Level 2 in the fair 
value hierarchy.

(10)          Unconsolidated Affiliates 

  CenterPoint Energy has the ability to significantly influence the operating and financial policies of Enable, a publicly traded 
MLP,  and,  accordingly,  accounts  for  its  investment  in  Enable’s  common  and  subordinated  units  using  the  equity  method  of 
accounting. See Note 2 for information on the formation of Enable.

CenterPoint Energy’s maximum exposure to loss related to Enable, a VIE in which CenterPoint Energy is not the primary 
beneficiary, is limited to its equity investment and Series A Preferred Unit investment as presented in the Consolidated Balance 
Sheet as of December 31, 2016  and outstanding current accounts receivable from Enable. On February 18, 2016, CenterPoint 
Energy purchased an aggregate of 14,520,000 Series A Preferred Units from Enable for a total purchase price of $363 million, 
which is accounted for as a cost method investment.  In connection with the purchase, Enable redeemed $363 million of notes 
owed to a wholly-owned subsidiary of CERC Corp., which bore interest at an annual rate of 2.10% to 2.45%. 

Effective on the Formation Date, CenterPoint Energy and Enable entered into the Transition Agreements. Under the Services 
Agreement, CenterPoint Energy agreed to provide certain support services to Enable such as accounting, legal, risk management 
and treasury functions for an initial term, which ended on April 30, 2016.  CenterPoint Energy is providing certain services to 
Enable on a year-to-year basis. Enable may terminate (i) the entire Services Agreement with at least 90 days’ notice prior to the 
end of any extension term, or (ii) either any service provided under the Services Agreement, or the entire Services Agreement, at 
any time upon approval by its board of directors and with at least 180 days’ notice.

CenterPoint Energy provided seconded employees to Enable to support its operations for a term ending on December 31, 
2014.  Enable, at its discretion, had the right to select and offer employment to seconded employees from CenterPoint Energy. 
During  the  fourth  quarter  of  2014,  Enable  notified  CenterPoint  Energy  that  it  selected  seconded  employees  and  provided 
employment offers to substantially all of the seconded employees from CenterPoint Energy. Substantially all of the seconded 
employees became employees of Enable effective January 1, 2015. 

In accordance with the Enable formation agreements, CenterPoint Energy had certain put rights, and Enable had certain call 
rights, exercisable with respect to the 25.05% interest in SESH retained by CenterPoint Energy. As of June 30, 2015, CenterPoint 
Energy’s remaining interest in SESH was transferred to Enable.

CenterPoint Energy evaluates its equity method investments for impairment when factors indicate that a decrease in the value 
of its investment has occurred and the carrying amount of its investment may not be recoverable. An impairment loss, based on 
the excess of the carrying value over estimated fair value of the investment, is recognized in earnings when an impairment is 
deemed to be other than temporary. Considerable judgment is used in determining if an impairment loss is other than temporary 
and the amount of any impairment.  Based on the sustained low Enable common unit price and further declines in such price 
during the year ended December 31, 2015, as well as the market outlook for continued depressed crude oil and natural gas prices 
impacting the midstream oil and gas industry, CenterPoint Energy determined that an other than temporary decrease in the value 
of its equity method investment in Enable had occurred.  CenterPoint Energy wrote down the value of its equity method investment 
in Enable to its estimated fair value which resulted in impairment charges of $1,225 million for the year ended December 31, 
2015.  Both  the  income  approach  and  market  approach  were  utilized  to  estimate  the  fair  value  of  CenterPoint  Energy’s  total 
investment in Enable, which includes the limited partner common and subordinated units, general partner interest and incentive 
distribution rights held by CenterPoint Energy. The determination of fair value considered a number of relevant factors including 
Enable’s common unit price and forecasted results, recent comparable transactions and the limited float of Enable’s publicly traded 
common units. See Note 9 for further discussion of the determination of fair value of CenterPoint Energy’s equity method investment 
in Enable in 2015. 

As of December 31, 2016, the carrying value of CenterPoint Energy’s equity method investment in Enable was $10.71 per 
unit, which includes limited partner common and subordinated units, a general partner interest and incentive distribution rights. 
On December 31, 2016, Enable’s common unit price closed at $15.73. There was no impairment indicated in 2016.

As there were no identified events or changes in circumstances that may have a significant adverse effect on the fair value of 
CenterPoint Energy’s cost method investment in Enable’s Series A Preferred Units as of December 31, 2016, and the investment’s 
fair value is not readily determinable, an estimate of the fair value of the cost method investment was not performed.

(2)  CenterPoint Energy contributed a 24.95% interest in SESH to Enable on May 30, 2014 and its remaining 0.1% interest 

in SESH to Enable on June 30, 2015.

As of December 31, 2016, CERC Corp. and OGE also own 40% and 60%, respectively, of the incentive distribution rights 
held by the general partner of Enable.  Enable is expected to pay a minimum quarterly distribution of $0.2875 per unit on its 
outstanding units to the extent it has sufficient cash from operations after establishment of cash reserves and payment of fees and 
expenses, including payments to its general partner and its affiliates, within 60 days after the end of each quarter. If cash distributions 
to Enable’s unitholders exceed $0.330625 per unit in any quarter, the general partner will receive increasing percentages or incentive 
distributions rights, up to 50%, of the cash Enable distributes in excess of that amount.  In certain circumstances the general partner 
of Enable will have the right to reset the minimum quarterly distribution and the target distribution levels at which the incentive 
distributions receive increasing percentages to higher levels based on Enable’s cash distributions at the time of the exercise of this 
reset election.  To date, no incentive distributions have been made.

(11)        Indexed Debt Securities (ZENS) and Securities Related to ZENS 

(a) Investment in Securities Related to ZENS

In 1995, CenterPoint Energy sold a cable television subsidiary to TW and received TW securities as partial consideration. A 
subsidiary of CenterPoint Energy now holds 7.1 million shares of TW Common, 0.9 million shares of Time Common and 0.9 
million shares of Charter Common, which are classified as trading securities and are expected to be held to facilitate CenterPoint 
Energy’s ability to meet its obligation under the ZENS. Unrealized gains and losses resulting from changes in the market value 
of the TW Securities are recorded in CenterPoint Energy’s Statements of Consolidated Income.

106

(b) ZENS

In September 1999, CenterPoint Energy issued ZENS having an original principal amount of $1 billion of which $828 million
remain outstanding at December 31, 2016. Each ZENS was originally exchangeable at the holder’s option at any time for an 
amount of cash equal to 95% of the market value of the reference shares of TW Common attributable to such note. The number 
and identity of the reference shares attributable to each ZENS are adjusted for certain corporate events.   Prior to the closing of 
the transactions discussed below, the reference shares for each ZENS consisted of 0.5 share of TW Common, 0.125505 share of 
TWC Common and 0.0625 share of Time Common.  

On May 26, 2015, Charter announced that it had entered into a definitive merger agreement with TWC. On September 21, 
2015, Charter shareholders approved the announced transaction with TWC. Pursuant to the merger agreement, upon closing of 
the merger, TWC Common would be exchanged for cash and Charter Common and as a result, reference shares for the ZENS 
would consist of Charter Common, TW Common and Time Common. The merger closed on May 18, 2016. CenterPoint Energy 
received $100 and 0.4891 shares of Charter Common for each share of TWC Common held, resulting in cash proceeds of $178 
million and 872,531 shares of Charter Common. In accordance with the terms of the ZENS, CenterPoint Energy remitted $178 
million to ZENS holders in June 2016, which reduced contingent principal.  

As a result, CenterPoint Energy recorded the following:

Cash payment to ZENS holders..................................... $
Indexed debt – reduction................................................
Indexed debt securities derivative – reduction...............
     Loss on indexed debt securities ................................ $

(in millions)

178
(40)
(21)
117

As of December 31, 2016, the reference shares for each ZENS consisted of 0.5 share of TW Common, 0.0625 share of Time 

Common and 0.061382 share of Charter Common.

On October 22, 2016, AT&T announced that it had entered into a definitive agreement to acquire TW in a stock and cash 
transaction.  Pursuant to the agreement, TW Common would be exchanged for cash and AT&T Common, and as a result, reference 
shares would consist of Charter Common, Time Common and AT&T Common. AT&T announced that the merger is expected to 
close by the end of 2017.

CenterPoint Energy pays interest on the ZENS at an annual rate of 2% plus the amount of any quarterly cash dividends paid 
in respect of the reference shares attributable to the ZENS. The principal amount of ZENS is subject to being increased or decreased 
to the extent that the annual yield from interest and cash dividends on the reference shares is less than or more than 2.309%. The 
adjusted principal amount is defined in the ZENS instrument as “contingent principal.” At December 31, 2016, ZENS having an 
original  principal  amount  of  $828  million  and  a  contingent  principal  amount  of  $514  million  were  outstanding  and  were 
exchangeable, at the option of the holders, for cash equal to 95% of the market value of reference shares deemed to be attributable 
to the ZENS. As of December 31, 2016, the market value of such shares was approximately $953 million, which would provide 
an exchange amount of $1,094 for each $1,000 original principal amount of ZENS. At maturity of the ZENS in 2029, CenterPoint 
Energy will be obligated to pay in cash the higher of the contingent principal amount of the ZENS or an amount based on the then-
current market value of the reference shares, which will include any additional publicly-traded securities distributed with respect 
to the current reference shares prior to maturity. 

The ZENS obligation is bifurcated into a debt component and a derivative component (the holder’s option to receive the 
appreciated value of the reference shares at maturity). The bifurcated debt component accretes through interest charges at 19.5%
annually up to the contingent principal amount of the ZENS in 2029. Such accretion will be reduced by annual cash interest 
payments, as described above. The derivative component is recorded at fair value and changes in the fair value of the derivative 
component are recorded in CenterPoint Energy’s Statements of Consolidated Income. Changes in the fair value of the TW Securities 
held by CenterPoint Energy are expected to substantially offset changes in the fair value of the derivative component of the ZENS.

(3)  NGD currently has AMAs associated with its utility distribution service in Arkansas, north Louisiana and Oklahoma that 
extend through 2020. Pursuant to the provisions of the agreements, NGD sells natural gas and agrees to repurchase an 
equivalent amount of natural gas during the winter heating seasons at the same cost, plus a financing charge. These 
transactions are accounted for as an inventory financing.

(4)  CenterPoint Energy’s ZENS obligation is bifurcated into a debt component and an embedded derivative component. For 
additional information regarding ZENS, see Note 11(b). As ZENS are exchangeable for cash at any time at the option of 
the holders, these notes are classified as a current portion of long-term debt.

(5)  $118 million of these series of debt were secured by general mortgage bonds of Houston Electric as of both December 31, 

2016 and 2015.

(6)  Classified as long-term debt because the termination date of the facility that backstops the commercial paper is more than 

one year from the date noted.

Long-term Debt

Debt Retirements.  In May 2016, CERC retired approximately $325 million aggregate principal amount of its 6.15% senior 

notes at their maturity.  The retirement of senior notes was financed by the issuance of commercial paper.  

In December, 2016, CenterPoint Energy redeemed $300 million aggregate principal amount of its outstanding 6.50% senior 
notes due 2018 at a redemption price equal to 100% of the principal amount thereof, plus accrued and unpaid interest thereon to 
but excluding the redemption date, plus the make-whole premium.  The make-whole premium associated with the redemption 
was approximately $22 million and was included in Other Income, net on the Statements of Consolidated Income.

In December 2016, Houston Electric retired $56 million of collateralized pollution control bonds that had been held for 
remarketing.  These bonds were not reflected on our consolidated financial statements because Houston Electric was both the 
obligor on the bonds and the current owner of the bonds.

Debt Issuances.  Houston Electric issued the following general mortgage bonds during 2016 and as of February 10, 2017 in 

2017.

The proceeds from the issuance of these bonds were used to repay short-term debt and for general corporate purposes.

Securitization Bonds.  As of December 31, 2016, Houston Electric had special purpose subsidiaries consisting of the Bond 
Companies, which it consolidates. The consolidated special purpose subsidiaries are wholly-owned, bankruptcy remote entities 
that were formed solely for the purpose of purchasing and owning transition or system restoration property through the issuance 
of transition bonds or system restoration bonds and activities incidental thereto.  These Securitization Bonds are payable only 
through  the  imposition  and  collection  of  “transition”  or  “system  restoration”  charges,  as  defined  in  the Texas  Public  Utility 
Regulatory Act, which are irrevocable, non-bypassable charges to provide recovery of authorized qualified costs.  Houston Electric 
has no payment obligations in respect of the Securitization Bonds other than to remit the applicable transition or system restoration 
charges it collects.  Each special purpose entity is the sole owner of the right to impose, collect and receive the applicable transition 
or system restoration charges securing the bonds issued by that entity.  Creditors of CenterPoint Energy or Houston Electric have 
no recourse to any assets or revenues of the Bond Companies (including the transition and system restoration charges), and the 
holders of Securitization Bonds have no recourse to the assets or revenues of CenterPoint Energy or Houston Electric.

(1)  Based on current credit ratings.

(2)  As defined in the revolving credit facility agreement, excluding Securitization Bonds.

(3)  The financial covenant limit will temporarily increase from 65% to 70% if Houston Electric experiences damage from 
a natural disaster in its service territory and CenterPoint Energy certifies to the administrative agent that Houston Electric 
has incurred system restoration costs reasonably likely to exceed $100 million in a consecutive twelve-month period, all 
or part of which Houston Electric intends to seek to recover through securitization financing. Such temporary increase 
in the financial covenant would be in effect from the date CenterPoint Energy delivers its certification until the earliest 
to occur of (i) the completion of the securitization financing, (ii) the first anniversary of CenterPoint Energy’s certification 
or (iii) the revocation of such certification.

CenterPoint Energy, Houston Electric and CERC Corp. were in compliance with all financial debt covenants as of December 31, 

2016.

Liens.  As of December 31, 2016, Houston Electric’s assets were subject to liens securing approximately $102 million of first 
mortgage bonds. Sinking or improvement fund and replacement fund requirements on the first mortgage bonds may be satisfied 
by certification of property additions. Sinking fund and replacement fund requirements for 2016, 2015 and 2014 have been satisfied 
by certification of property additions. The replacement fund requirement to be satisfied in 2017 is approximately $240 million,  
and the sinking fund requirement to be satisfied in 2017 is approximately $1.6 million. CenterPoint Energy expects Houston 
Electric to meet these 2017 obligations by certification of property additions. As of December 31, 2016, Houston Electric’s assets 
were also subject to liens securing approximately $2.6 billion of general mortgage bonds, which are junior to the liens of the first 
mortgage bonds.

In 2016, CenterPoint Energy recognized a $6 million deferred tax expense due to Louisiana state law change and recorded 

an additional $3 million valuation allowance on certain state carryforwards.

In 2015, CenterPoint Energy’s effective tax rate was higher than the statutory rate primarily due to lower earnings from the 
impairment of CenterPoint Energy’s equity method investment in Enable. The impairment loss reduced the deferred tax liability 
on CenterPoint Energy’s equity method investment in Enable.

In 2014, CenterPoint Energy recognized a $29 million deferred income tax benefit upon completion of its tax basis balance 
sheet review.  The adjustment resulted in a decrease to deferred tax liabilities of $32 million, a decrease to income taxes payable 
of $5 million and a decrease to income tax regulatory assets of $8 million.  CenterPoint Energy determined the impact of the $29 
million adjustment was not material to any prior period or the year ended December 31, 2014.

Tax Attribute  Carryforwards  and  Valuation Allowance.  CenterPoint  Energy  has  no  remaining  federal  net  operating  loss 
carryforward or federal tax credits as of December 31, 2016. CenterPoint Energy has $962 million of state net operating loss 
carryforwards that expire between 2017 and 2036, $11 million of state tax credits that do not expire and $244 million of state 
capital loss carryforwards that expire in 2017.  CenterPoint Energy reported a tax-effected valuation allowance of $5 million
because it is more likely than not that the benefit from certain state carryforwards will not be realized.

Uncertain Income Tax Positions.  CenterPoint Energy reported no uncertain tax liability as of December 31, 2016, 2015 and 

2014.  We expect no significant change to the uncertain tax liability over the next twelve months ending December 31, 2017. 

Tax Audits and Settlements.   Tax years through 2014 have been audited and settled with the IRS. For the 2015, 2016 and 

2017 tax years, CenterPoint Energy is a participant in the IRS’s Compliance Assurance Process. 

(15)        Commitments and Contingencies 

(a) Natural Gas Supply Commitments

Natural gas supply commitments include natural gas contracts related to CenterPoint Energy’s Natural Gas Distribution and 
Energy Services business segments, which have various quantity requirements and durations, that are not classified as non-trading 
derivative assets and liabilities in CenterPoint Energy’s Consolidated Balance Sheets as of December 31, 2016 and 2015 as these 
contracts meet an exception as “normal purchases contracts” or do not meet the definition of a derivative. Natural gas supply 
commitments also include natural gas transportation contracts that do not meet the definition of a derivative. As of December 31, 
2016, minimum payment obligations for natural gas supply commitments are approximately:

(b) AMAs

NGD has had AMAs associated with its utility distribution service in Arkansas, Louisiana, Mississippi, Oklahoma and Texas. 
Generally, AMAs are contracts between NGD and an asset manager that are intended to transfer the working capital obligation 
and maximize the utilization of the assets.  In these AMAs, NGD agrees to release transportation and storage capacity to other 
parties to manage natural gas storage, supply and delivery arrangements for NGD and to use the released capacity for other purposes 
when it is not needed for NGD. NGD is compensated by the asset manager through payments made over the life of the AMAs 
based in part on the results of the asset optimization. NGD has an obligation to purchase its winter storage requirements that have 
been released to the asset manager under these AMAs. NGD has received approval from the state regulatory commissions in 
Arkansas, Louisiana, Mississippi and Oklahoma to retain a share of the AMA proceeds. NGD currently has AMAs in Arkansas, 
north Louisiana and Oklahoma that extend through 2020.

(c) Lease Commitments

The  following  table  sets  forth  information  concerning  CenterPoint  Energy’s  obligations  under  non-cancelable  long-term 
operating  leases  as  of  December 31,  2016,  which  primarily  consist  of  rental  agreements  for  building  space,  data  processing 
equipment, compression equipment and rights-of-way:

respectively.

(d) Legal, Environmental and Other Matters

Legal Matters

Gas Market Manipulation Cases.  CenterPoint Energy, Houston Electric or their predecessor, Reliant Energy, and certain of 
their former subsidiaries have been named as defendants in certain lawsuits described below.  Under a master separation agreement 
between CenterPoint Energy and a former subsidiary, RRI, CenterPoint Energy and its subsidiaries are entitled to be indemnified 
by RRI and its successors for any losses, including certain attorneys’ fees and other costs, arising out of these lawsuits.  In May 
2009, RRI sold its Texas retail business to a subsidiary of NRG and RRI changed its name to RRI Energy, Inc.  In December 2010, 
Mirant Corporation merged with and became a wholly-owned subsidiary of RRI, and RRI changed its name to GenOn. In December 
2012, NRG acquired GenOn through a merger in which GenOn became a wholly-owned subsidiary of NRG.  None of the sale of 
the retail business, the merger with Mirant Corporation, or the acquisition of GenOn by NRG alters RRI’s (now GenOn’s) contractual 
obligations to indemnify CenterPoint Energy and its subsidiaries, including Houston Electric, for certain liabilities, including their 
indemnification obligations regarding the gas market manipulation litigation.

A large number of lawsuits were filed against numerous gas market participants in a number of federal and western state 
courts in connection with the operation of the natural gas markets in 2000–2002.  CenterPoint Energy and its affiliates have since 
been released or dismissed from all such cases.  CES, a subsidiary of CERC Corp., was a defendant in a case now pending in 
federal court in Nevada alleging a conspiracy to inflate Wisconsin natural gas prices in 2000–2002.  On May 24, 2016, the district 
court granted CES’s motion for summary judgment, dismissing CES from the case.  The plaintiffs have appealed that ruling.  
CenterPoint Energy and CES intend to continue vigorously defending against the plaintiffs’ claims.  CenterPoint Energy does not 
expect the ultimate outcome of this matter to have a material adverse effect on its financial condition, results of operations or cash 
flows. 

114

Environmental Matters

MGP Sites. CERC and its predecessors operated MGPs in the past.  With respect to certain Minnesota MGP sites, CERC has 
completed state-ordered remediation and continues state-ordered monitoring and water treatment.  As of December 31, 2016, 
CERC  had  a  recorded  liability  of  $7  million  for  continued  monitoring  and  any  future  remediation  required  by  regulators  in 
Minnesota.  The estimated range of possible remediation costs for the sites for which CERC believes it may have responsibility 
was $5 million to $30 million based on remediation continuing for 30 to 50 years. The cost estimates are based on studies of a 
site or industry average costs for remediation of sites of similar size.  The actual remediation costs will depend on the number of 
sites to be remediated, the participation of other PRPs, if any, and the remediation methods used.  

In addition to the Minnesota sites, the EPA and other regulators have investigated MGP sites that were owned or operated by 
CERC or may have been owned by one of its former affiliates.  CenterPoint Energy does not expect the ultimate outcome of these 
matters to have a material adverse effect on the financial condition, results of operations or cash flows of either CenterPoint Energy 
or CERC.

Asbestos. Some facilities owned by CenterPoint Energy or its predecessors contain or have contained asbestos insulation and 
other asbestos-containing materials.  CenterPoint Energy and its subsidiaries are from time to time named, along with numerous 
others, as defendants in lawsuits filed by a number of individuals who claim injury due to exposure to asbestos, and CenterPoint 
Energy anticipates that additional claims may be asserted in the future.  Although their ultimate outcome cannot be predicted at 
this time, CenterPoint Energy does not expect these matters, either individually or in the aggregate, to have a material adverse 
effect on CenterPoint Energy’s financial condition, results of operations or cash flows.

Other Environmental. From time to time CenterPoint Energy identifies the presence of environmental contaminants during 
its operations or on property where its predecessor companies have conducted operations.  Other such sites involving contaminants 
may be identified in the future.  CenterPoint Energy has and expects to continue to remediate identified sites consistent with its 
legal obligations.  From time to time CenterPoint Energy has received notices from regulatory authorities or others regarding its 
status as a PRP in connection with sites found to require remediation due to the presence of environmental contaminants.  In 
addition, CenterPoint Energy has been named from time to time as a defendant in litigation related to such sites.  Although the 
ultimate  outcome  of  such  matters  cannot  be  predicted  at  this  time,  CenterPoint  Energy  does  not  expect  these  matters,  either 
individually or in the aggregate, to have a material adverse effect on CenterPoint Energy’s financial condition, results of operations 
or cash flows.

Other Proceedings

CenterPoint Energy is involved in other legal, environmental, tax and regulatory proceedings before various courts, regulatory 
commissions  and  governmental  agencies  regarding  matters  arising  in  the  ordinary  course  of  business.    From  time  to  time, 
CenterPoint Energy is also a defendant in legal proceedings with respect to claims brought by various plaintiffs against broad 
groups of participants in the energy industry.  Some of these proceedings involve substantial amounts.  CenterPoint Energy regularly 
analyzes current information and, as necessary, provides accruals for probable and reasonably estimable liabilities on the eventual 
disposition of these matters.  CenterPoint Energy does not expect the disposition of these matters to have a material adverse effect 
on CenterPoint Energy’s financial condition, results of operations or cash flows.

(18)        Reportable Business Segments 

CenterPoint  Energy’s  determination  of  reportable  business  segments  considers  the  strategic  operating  units  under  which 
CenterPoint Energy manages sales, allocates resources and assesses performance of various products and services to wholesale 
or retail customers in differing regulatory environments. CenterPoint Energy uses operating income as the measure of profit or 
loss for its business segments other than Midstream Investments, where it uses equity in earnings.

CenterPoint Energy’s reportable business segments include the following: Electric Transmission & Distribution, Natural Gas 
Distribution, Energy Services, Midstream Investments and Other Operations. The electric transmission and distribution function 
(Houston Electric) is reported in the Electric Transmission & Distribution business segment. Natural Gas Distribution consists of 
intrastate natural gas sales to, and natural gas transportation and distribution for, residential, commercial, industrial and institutional 
customers. Energy Services represents CenterPoint Energy’s non-rate regulated gas sales and services operations. Midstream 
Investments consists of CenterPoint Energy’s equity investment in Enable. Other Operations consists primarily of other corporate 
operations which support all of CenterPoint Energy’s business operations.

Long-lived  assets  include  net  property,  plant  and  equipment,  goodwill  and  other  intangibles  and  equity  investments  in 

unconsolidated subsidiaries. Intersegment sales are eliminated in consolidation.

(19)        Subsequent Events 

On January 5, 2017, CenterPoint Energy’s board of directors declared a regular quarterly cash dividend of $0.2675 per share 

of common stock payable on March 10, 2017, to shareholders of record as of the close of business on February 16, 2017.

On January 3, 2017, CES, an indirect, wholly-owned subsidiary of CenterPoint Energy, closed the previously announced 
agreement to acquire AEM for approximately $140 million, including estimated working capital of $100 million. With the addition 
of this business, CES now operates in a total of 33 states, including seven states where CES previously had no commercial or 
industrial natural gas sales customers though CES did have other operations in five of those states. CES has begun to integrate 
AEM into its existing business.  Due to the limited amount of time since the acquisition, the initial accounting for the acquisition 
is incomplete, principally with regard to the valuation of derivatives, property, plant and equipment, intangible assets and goodwill. 
CenterPoint Energy intends to provide additional business combination disclosures, if material, in its Form 10-Q for the first 
quarter of 2017.

On February 10, 2017, Enable declared a quarterly cash distribution of $0.318 per unit on all of its outstanding common and 
subordinated units for the quarter ended December 31, 2016.  Accordingly, CERC Corp. expects to receive a cash distribution of 
approximately $74 million from Enable in the first quarter of 2017 to be made with respect to CERC Corp.’s limited partner interest 
in Enable for the fourth quarter of 2016.  

118

On February 10, 2017, Enable declared a quarterly cash distribution of $0.625 per Series A Preferred Unit for the quarter 
ended December 31, 2016.  Accordingly, CenterPoint Energy expects to receive a cash distribution of approximately $9 million
from Enable in the first quarter of 2017 to be made with respect to CenterPoint Energy’s investment in Series A Preferred Units 
of Enable for the fourth quarter of 2016.

Item 9A.  Controls and Procedures

Disclosure Controls And Procedures

In accordance with Exchange Act Rules 13a-15 and 15d-15, we carried out an evaluation, under the supervision and with the 
participation of management, including our principal executive officer and principal financial officer, of the effectiveness of our 
disclosure controls and procedures as of the end of the period covered by this report. Based on that evaluation, our principal 
executive  officer  and  principal  financial  officer  concluded  that  our  disclosure  controls  and  procedures  were  effective  as  of 
December 31, 2016 to provide assurance that information required to be disclosed in our reports filed or submitted under the 
Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange 
Commission’s rules and forms and such information is accumulated and communicated to our management, including our principal 
executive officer and principal financial officer, as appropriate to allow timely decisions regarding disclosure.

There  has  been  no  change  in  our  internal  controls  over  financial  reporting  that  occurred  during  the  three  months  ended 
December 31, 2016 that has materially affected, or is reasonably likely to materially affect, our internal controls over financial 
reporting.

Management’s Annual Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Internal 
control over financial reporting is defined in Rule 13a-15(f) or 15d-15(f) promulgated under the Securities Exchange Act of 1934 
as a process designed by, or under the supervision of, the company’s principal executive and principal financial officers and effected 
by the company’s board of directors, management and other personnel, 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 and includes those policies and procedures that:

• 

• 

• 

Pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions 
of the assets of the company;

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

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.

Management has designed its internal control over financial reporting to provide reasonable assurance regarding the reliability 
of financial reporting and the preparation of financial statements in accordance with accounting principles generally accepted in 
the United States of America. Management’s assessment included review and testing of both the design effectiveness and operating 
effectiveness of controls over all relevant assertions related to all significant accounts and disclosures in the financial statements.

All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined 
to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation. 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.

Under the supervision and with the participation of our management, including our principal executive officer and principal 
financial officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting based on the 
framework in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the 
119

Treadway Commission. Based on our evaluation under the framework in Internal Control — Integrated Framework (2013), our 
management has concluded that our internal control over financial reporting was effective as of December 31, 2016.

Deloitte & Touche LLP, the Company’s independent registered public accounting firm, has issued an attestation report on the 

effectiveness of our internal control over financial reporting as of December 31, 2016 which is set forth below.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders of
CenterPoint Energy, Inc.
Houston, Texas

We have audited the internal control over financial reporting of CenterPoint Energy, Inc. and subsidiaries (the “Company”) 
as of December 31, 2016, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee 
of Sponsoring Organizations of the Treadway Commission.  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 conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States).  
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.

A company’s internal control over financial reporting is a process designed by, or under the supervision of, the company’s 
principal executive and principal financial officers, or persons performing similar functions, and effected by the company’s board 
of directors, management, and other personnel 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 the inherent limitations of internal control over financial reporting, including the possibility of collusion or improper 
management override of controls, material misstatements due to error or fraud may not be prevented or detected on a timely basis.  
Also, projections of any evaluation of the effectiveness of the internal control over financial reporting to future periods are subject 
to the risk that the controls may become inadequate because of changes in conditions, or that the degree of compliance with the 
policies or procedures may deteriorate.

In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of 
December 31, 2016, based on the criteria established in Internal Control — Integrated Framework (2013) issued by the Committee 
of Sponsoring Organizations of the Treadway Commission.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), 
the  consolidated  financial  statements  as  of  and  for  the  year  ended  December 31,  2016  of  the  Company  and  our  report  dated 
February 28, 2017 expressed an unqualified opinion on those financial statements.
