# Our POINT of VIEW



From top:

MILTON CARROLL

Chairman of the Board

SCOTT M. PROCHAZKA

President & CEO

Dear Fellow Shareholders,

The year 2013 marked the beginning of an important transition period for your company. On May 1, we combined our interstate pipeline and field services businesses with the midstream operations of OGE Energy and ArcLight Capital to create a new master limited partnership: Enable Midstream Partners. With this move, we hope to provide greater transparency for a significant part of our asset portfolio and thereby maximize shareholder value. We also believe that the larger combined business can grow at a faster pace and compete on a stronger footing than was possible for two smaller, separate companies.

Through our investment in Enable Midstream, we will continue to participate in the build-out of our nation’s oil, natural gas and natural gas liquids transportation infrastructure. Over the coming years, we believe this investment will create great value for our shareholders by providing significant cash distributions to CenterPoint Energy.

The creation of Enable Midstream provides another important benefit: It allows us to sharpen our focus on our core businesses, our electric and natural gas utilities. With strong customer growth in our service territories, generally supportive regulatory environments and significant capital investment opportunities, we believe we are well positioned for ongoing success.

Finally, we have reviewed our dividend policy due to the creation of Enable Midstream. We will target a dividend payout that reflects 60-70 percent of the sustainable earnings from our regulated utility operations and 90-100 percent of the net after-tax cash distributions from Enable Midstream. As a result, we increased our quarterly dividend by 14.5 percent to $0.2375 per share. This was our ninth consecutive year of dividend increases.

## 2013 Overview

Our utilities turned in solid performances last year and helped us earn $311 million in net income. Due in large part to the accounting complexities stemming from the creation of Enable Midstream, it is difficult to compare these results with the $417 million in net income we reported in 2012. The creation of Enable Midstream triggered an unusual, one-time increase in our income tax expense and changed the way we account for midstream earnings. A description of these changes and a detailed comparison of our 2013 and 2012 net income results can be found on page 47 of our form 10-K. We encourage you to read it.

As we review and manage our utilities, we have found that core operating income, which excludes the effects of transition and system restoration bonds, is the most meaningful guide to our underlying business performance. By this measure, 2013 was a good year, and we once again saw the benefits of our diversified portfolio. Our natural gas business had another record year, more than offsetting a slight decline in operating income at our electric utility that was caused primarily by cooler summer weather. Combined, core operating income from our natural gas operations, competitive energy services business



## SHAREHOLDER LETTER (cont)

and electric operations was $750 million, an increase of $30 million compared with 2012. This excludes a $252 million non-cash goodwill impairment charge recorded in 2012 associated with the competitive energy services business.

Total shareholder returns last year were excellent as well. Including stock price appreciation and annual dividends, CenterPoint Energy stock returned 24.7 percent and outperformed our peers, as measured by the S&P 500 Utilities Index, which returned 8.8 percent. However, we lagged the broader market S&P 500 Index, which returned 32.4 percent. Over the longer-term our three-year, five-year and 10-year total shareholder returns have exceeded those of our peers and the market as a whole.

## Business Segment Results

We saw continued growth in our electric transmission and distribution business last year. We added more than 44,000 new customers and recorded approximately $30 million in right-of-way revenues, which is substantially above historical levels of $2 million to $3 million per year. However, a milder summer and higher property taxes reduced core operating income to $474 million, compared with $492 million in 2012.

Our customers and company are seeing the benefits of our smart meter and intelligent grid deployments. Smart meters provide faster, more accurate meter readings and enable us to start, stop and transfer service without ever rolling a truck. Where intelligent grid technology is in place, automated switches with line-sensing capabilities have led to a 25 percent reduction in customer outage minutes. Our smart meter deployment is already complete, and we hope to have our intelligent grid technologies fully deployed in the next 10 years.

In 2013, our natural gas distribution business set another record. Core operating income for the year was $263 million, compared with $226 million in 2012. Rate relief, growth, cost management efforts and a return to more normal weather, were key drivers. Our competitive energy services business contributed an additional $13 million in operating income last year.

Effective rate designs across our service territories are providing us greater opportunity for timely cost recovery and to earn our authorized rates of return. Over the past several years, we have made significant investments in system integrity in Minnesota, and as a result we are requesting a $44.3 million increase in our base rates there. Interim rates went into effect Oct. 1, and we expect a final decision in mid-2014.

Across the rest of our service territory, we continue to make substantial investments in automation and pipeline integrity projects. Over the past decade, we have replaced half of the cast iron pipe in our system and nearly a third of the bare steel pipe. In addition, we are well on our way toward deploying advanced, drive-by meter reading technology in all our jurisdictions. On average, this will allow a single employee to take 10,000 meter readings per day, compared with 500 per day on foot.

Prior to the formation of Enable Midstream Partners on May 1, our midstream business contributed $145 million in operating income and $7 million in equity income from our investment in the Southeast Supply Header (SESH). Following the creation of the limited partnership, our investment in Enable Midstream yielded $173 million in equity earnings, with an additional $8 million from SESH. The partnership continues to do well in a challenging operating environment characterized by low commodity prices and compressed geographic price differentials. Earnings from processing and wet gas gathering continue to grow, although these are partially offset by reduced demand for ancillary pipeline services and significantly reduced drilling activity in dry gas basins. In January 2014, Enable Midstream announced it had hired Lynn L. Bourdon III to be its president and CEO. Enable Midstream remains on track for an initial public offering in the first half of 2014.

## 2013 Highlights

Our natural gas distribution business had a record year with $263 million in operating income.

We installed intelligent grid equipment that serves 13 percent of consumers, resulting in a 25 percent improvement in power outage restoration.

CenterPoint Energy owns a 58.3 percent limited partner interest in Enable Midstream Partners, one of the largest midstream companies in America.

Safety, while always our number one priority, was added to our core values of integrity, accountability, initiative and respect. These values reflect the basic ethical principles that guide our conduct every day.

Commitment to our communities goes beyond delivering energy. In 2013, our employees, retirees, family members and friends dedicated 223,000 volunteer hours, valued conservatively at $5 million.

CenterPoint Energy was recognized by the Edison Electric Institute, Women’s Enterprise magazine and Minority Business News USA for our supplier diversity efforts.



“Today,
CenterPoint
Energy is
stronger
and more
financially
secure than
we have
ever been.”

## Refining Our Vision For The Next Decade

Since becoming a stand-alone company more than 10 years ago, CenterPoint Energy has been guided by a corporate vision “to be recognized as America’s leading energy delivery company ... and more.” This vision has served us well, helping us focus our efforts and guiding us through a decade that included the collapse of energy credit markets, multiple hurricane strikes, extreme natural gas price volatility and a protracted electric true-up case that slowed our ability to reduce debt and improve our balance sheet. Today, CenterPoint Energy is stronger and more financially secure than we have ever been.

But where do we go from here? With the creation of Enable Midstream and the transition to our next generation of leadership, we felt the time was right to step back and re-examine our vision, values and corporate strategy. Were they the right ones to guide us through the next decade? We examined market trends, studied the performance of our peers and evaluated our own core competencies – all with the goal of making sure we had the right strategy in place to provide our investors with a secure, competitive dividend and earnings growth.

In summary, we found CenterPoint Energy occupies an almost unique position within the utility industry. Thanks in part to strong growth in Minneapolis and Houston, we believe we are one of only a handful of utilities in the country with significant, organic growth prospects. By combining growing electric demand, our intelligent grid deployment and reliability infrastructure investments in our natural gas distribution system, we will have the opportunity to significantly grow the rate base of our utilities.

While our core strategy is to invest in the infrastructure needs of our existing utilities, we will continue to selectively evaluate merger and acquisition opportunities. We do not believe a significant merger and acquisition transaction is required for us to meet our business objectives, but will continue to look for strategic opportunities that will enhance value for our shareholders. This should allow us to achieve our financial goals while maintaining our low-risk investment profile.

In addition to revising our strategy, we sharpened our company vision and values. Our new vision is to Lead the Nation in Delivering Energy, Service and Value. It emphasizes that delivering energy remains our core business and reflects our desire to continue performing at industry-leading levels. It also signifies our enduring commitment to deliver value to all our stakeholders. For our customers, our vision promises reliable, affordable and innovative service. For our employees, it represents our commitment to maintain an attractive, dynamic work environment. For the communities we serve, it means we will continue to be responsible corporate citizens and good environmental stewards. And for our shareholders, it means we intend to deliver a secure dividend, low-risk growth and peer-leading returns.

We are proud of the way we do our work, and after reviewing our company’s values of integrity, accountability, initiative and respect, we determined they were on point, with one exception. Safety has always been an important part of our company’s culture. To reinforce our commitment to operate a safe system and perform our jobs safely at all times, we added safety as a core value.

## The Road Ahead

Before looking ahead to the next steps on our company’s journey, we would like to take a moment to look back at the road just traveled, and in particular, at the man who led CenterPoint Energy on that journey: former CEO David McClanahan.

David navigated CenterPoint Energy from its inception through some of the most difficult challenges any company will ever face. The theme of this year’s annual report, “On Point” not only reflects our belief that we have the right vision, strategy and values for the future, but it also acknowledges the successes that brought us to this point. Since our inception in 2002, our cumulative shareholder return is an astonishing 367 percent, exceeding that of the S&P Utilities Index by 147 percent. David’s vision, integrity and disciplined approach



## SHAREHOLDER LETTER (cont)

to decision-making were vital in creating the strong financial and cultural foundation we enjoy today. We thank David for everything he has done to make CenterPoint Energy a truly remarkable company.

Our challenge now is to build on this legacy of success. In the short to medium term, we believe the development of energy from shale is going to keep natural gas and electricity prices low. This should drive robust commercial and industrial growth and require additional capital investments to serve this growing demand. Investments to modernize and expand our existing natural gas and electric infrastructure should continue to provide growth in our rate base. As a result, we anticipate investing approximately $6 billion in natural gas and electric capital projects over the next five years.

The nature of utility service itself is undergoing a fundamental transformation. Increasingly, utility customers will have the ability to choose when they consume energy and where they will get it – it could be from a traditional supplier or from a customer’s own sources, such as rooftop solar panels or gas-fired distributed generation. In this environment, utilities will become the advanced networks that connect these sources, and successful utilities will be those that become trusted partners working with customers and providing the complementary services that make it all work.

To prepare for this future, we are making strategic investments in technology now. In addition to our intelligent electric grid, we are investing in an advanced distribution management system and a Power Alert Service. This service automatically notifies customers by SMS text, email or phone when they have an outage and provides an estimate of when service will be restored. On the natural gas side of our business, we're deploying a new customer relationship management system that will allow us to provide faster, more personalized service. We plan to roll out a new, mobile-friendly website in 2014 as well. Taken together, we are committed to providing innovative products and services that complement our existing offerings and demonstrate to our customers that we are more than just their utility – we are their trusted energy advisers.

We’re excited about our long-term prospects. We have the right vision, strategy and values as well as a balanced portfolio of assets. We have the right leaders and capable employees needed to deliver a unique combination of low-risk growth and competitive dividends. We appreciate your confidence and investment in CenterPoint Energy, and we look forward to working for you.

# Our POINT of PROGRESS



## Dear Shareholders,

It has been an honor and a privilege to serve as CenterPoint Energy’s president and CEO the past 12 years. When I started at Houston Lighting & Power Company in 1972, I never expected to spend my entire career with one company, nor did I dream that I might someday be CEO of a Fortune 500 company. It was my good fortune that both of those possibilities became realities.

When I was named CenterPoint Energy’s first CEO in 2002, the company faced some stiff challenges and an uncertain future. The electricity market in Texas had just been completely restructured, and the rules were still being developed. The capital markets were challenging and wary of all energy companies following the Enron debacle. At the same time, we were highly leveraged and needed access to the capital markets to refinance debt and finance necessary infrastructure investments. The company’s future was less than clear.

However, we had a lot going for us. Our workforce was second to none. We had a plan to recapitalize the company by selling our electric generating plants and, through the regulatory process, recovering our capital investments that had been “stranded” by the restructuring of the Texas electric market. Just as important, we had a vision to create America’s leading energy delivery company based on a foundation of core values and key strategies. It was a vision that would keep us focused and striving for excellence.

Although deleveraging the company took longer than we expected, we ultimately accomplished this goal, and the company is now in sound financial shape. Our senior leadership team embraced the company’s vision and never wavered despite a number of significant challenges along the way. Our employees pulled together to get us through the early days, redesigned internal processes and systems to achieve top-tier operating performance and led the industry in implementing new technology. We also invested in new infrastructure to assure that energy was reliably and safely delivered to our customers. The CenterPoint Energy of today was truly created through a great team effort. I could not be more proud of this accomplishment.

As I begin my retirement there is not a better person to lead the company than Scott Prochazka. I’ve worked with Scott during my entire tenure as CEO. He knows and understands the company’s businesses well. He is bright, articulate, passionate about our company, and he has strong values and a great internal compass. I’m excited about the future of CenterPoint Energy with Scott at the helm.

Let me close by first thanking you, our shareholders, for your support over the years. Most of all, however, I would like to thank my fellow employees. Through their hard work and commitment we have accomplished a lot. They are the reason I stayed with the company for 42 years. Together we have created a very special company.

# POINT
SERVICE



## POINT OF SERVICE

## ELECTRIC TRANSMISSION
& DISTRIBUTION

2013 was a solid year for our electric transmission and distribution business. Steady growth in our service territory continued, with the addition of more than 44,000 metered customers. Operating income was $607 million, consisting of $474 million from the electric utility and $133 million related to transition and system restoration bonds. This compares with operating income of $639 million in 2012, with $492 million coming from the electric utility and $147 million from transition and system restoration bonds.

Last year, we completed installation of intelligent grid infrastructure that serves approximately 280,000 of our 2.2 million customers. The intelligent grid is a collection of sensors and switches installed on power lines, controlled by computers that automatically monitor and manage the flow of electricity on a distribution network. In areas where the new infrastructure is in place, we have reduced overall customer outage minutes by 25 percent. We plan to deploy this technology throughout our system, and we estimate completion within the next 10 years.

We’re continuing to make substantial investments in response to robust economic growth in the Houston area. We began construction of several new substations, most notably, one near the Houston Ship Channel that will support significant industrial load growth. We anticipate completion by mid-2014. In 2015, we expect to place in service a major transmission system upgrade in the Freeport, Texas, area. It will enhance reliability and provide storm-hardening benefits, which are important given Freeport’s close proximity to the Gulf of Mexico.

We currently have nine high-voltage transmission lines importing electricity to the region, and last year we submitted a proposal to the Electric Reliability Council of Texas to increase our import capacity to meet growing demand. Based on our load forecast, this additional capacity will be needed no later than the summer of 2018.

The company is also preparing for changes in the workforce, investing in hiring and employee development. National labor forecasts suggest that 30–50 percent of the utility workforce will be eligible for retirement within the next two to five years. In 2013, we increased hiring by more than 25 percent in many critical job areas, and we are creating new training programs to develop and enhance employees' skillsets and foster knowledge transfer.

## 1 Industry Leadership

We won industry excellence awards from the Southeastern Electric Exchange and the Electric Power Research Institute for our industry-leading role in a prototype extra-high voltage transformer installation drill. A typical substation transformer of this type takes 12-24 months to replace, but the prototype was transported and operational in only five days. Functioning for over a year, the prototype demonstrates the potential for rapid recovery from large-scale outages.

## 2 Electric Infrastructure Investment

To meet growing electric demand, we continue to make substantial investments in electric infrastructure including high-voltage transmission power lines and substations. A new substation near the Houston Ship Channel will support significant industrial load growth, and new equipment in north Houston will serve the planned Exxon Mobil campus and surrounding development.

## 3 Emergency Preparedness

The annual Hurricane Workshop, presented in partnership with Harris County and the city of Houston, prepares residents for hurricane season through presentations, interactive exhibits, hurricane forecasting and more. The free workshop is the largest of its kind in the nation with more than 2,500 attendees each year.

## 4 Energy Insight Center

At our Energy Insight Center, we demonstrate intelligent grid technology and the future of electricity. We’ve hosted elected officials, regulators and other utility companies from every continent except Antarctica. Visitors see demonstrations of the intelligent grid rerouting power during an outage, our Power Alert Service, smart appliances and more.

## 5 Intelligent Grid

In conjunction with smart meters, the intelligent grid more accurately identifies outage locations and improves service restoration. In areas where grid automation is in place, we have seen a 25 percent decrease in customer outage minutes.

## 6 Smart Meters

Smart meters have enabled us to complete nearly 8 million service orders electronically, saving 770,000 gallons of fuel, avoiding 7,000 metric tons of  \( CO_{2} \)  emissions and saving customers more than 24 million in fees formerly associated with manually carrying out those orders.



## 2013 Highlights

Added more than 44,000 new customers, growth of 2 percent

Enhanced vegetation management and equipment inspection programs to improve reliability
Increased hiring by more than 25 percent in many critical job areas, and we are creating new training programs to develop and enhance employee skillsets and foster knowledge transfer

Continued construction of a redundant transmission control center to ensure compliance with applicable federal reliability standards
Recognized as a leading utility in the adoption of intelligent grid technology by electric industry trade associations, technology partners and global research firms






## Natural Gas Distribution

“Our natural gas distribution business is benefiting from continued growth in key parts of our service territory and is well positioned for long-term success. We have increased base rates and implemented rate recovery mechanisms that ensure timely and full recovery of our investments. As a result, we’re earning our authorized rates of return. We’re also operating more efficiently than ever and investing in system safety and reliability for the benefit of our customers, our communities and our employees.”

JOE McGOLDRICK
President, Natural Gas Division

## POINT of EFFICIENCY







## POINT OF EFFICIENCY

## NATURAL GAS DISTRIBUTION

Our natural gas distribution business had a record year financially, thanks to rate relief, growth, cost management efforts and a return to more normal weather. Operating income for the year was $263 million, far exceeding the previous high of $231 million, set in 2010.

Capturing operational efficiencies continued to be a focal point of our efforts, and we saw significant progress in this area. We completed deployment of our advanced meter reading technology in Oklahoma and in parts of our territory in Louisiana, Minnesota and Texas; we are on schedule to complete deployment to our entire system by the end of 2015. Drive-by meter reading enables us to read 10,000 meters per day per vehicle, as opposed to 500 meters per person. We’re also able to read meters more accurately, without accessing our customers’ premises.

Economic growth across our footprint helped us add more than 33,000 customers, led by the greater Houston area and Minneapolis. An initiative in our Oklahoma service territory has, for the first time, given us access to provide natural gas services to developers of multi-family residences, which we expect to help fuel growth in that market as well.

Increased focus on the safety of the nation’s pipeline infrastructure will result in ongoing capital investment for system modernization. In 2013, we continued to replace remaining cast iron and bare steel pipe across our entire gas distribution system. In Minneapolis, we completed the first phase of a 72-mile pipeline rehabilitation project. This project, which includes pipe replacement and refurbishment, is part of our Minnesota distribution system. Capital expenditures for 2014 are forecast to exceed $520 million, as we continue to enhance our system’s safety and reliability.

We are investing in ways to improve our customers' experience when doing business with us by launching new self-service tools, such as a new website, optimized for both desktop and mobile devices, and an enhanced automated phone system. We will also provide call center agents with enabling technologies that maximize their performance, even in the face of more complex interactions.

Our ongoing efforts to provide our customers with the best possible service were validated by placing second among the largest South Region utilities, and a top-quartile finish among Midwest utilities, in the J.D. Power and Associates 2013 Gas Utility Residential Customer Satisfaction Study. \( ^{SM} \) 

## 1 Pipeline Safety and Integrity

In the past 10 years, we have replaced 49 percent of 728 miles of cast iron pipe and 31 percent of the 3,450 miles of bare steel pipe. In 2014, we plan to invest more than $300 million in system safety and integrity.

## 2 Energy-Efficiency Programs

By offering rebates to both residential and business customers, our conservation improvement programs in Arkansas, Minnesota and Oklahoma encourage the purchase of energy-efficient equipment. In 2013, the programs saved approximately 1.92 billion cubic feet of natural gas, the amount used annually by more than 16,000 homes. These programs also reduced total carbon footprint by 102,700 metric tons, or enough to remove 17,100 cars from roads for one year.

## 3 Compressed Natural Gas Fueling Stations

We support the growth of compressed natural gas as a vehicle fuel. In addition to CNG fueling stations for our own vehicles, we are providing fuel at public and other private stations. Natural gas vehicles have been shown to achieve dramatically lower levels of carbon emissions compared with those using gasoline.

## 4 Community Partnership Grants

In 2013, our Community Partnership Grant Program surpassed $1 million in donations, funding safety-related equipment and projects. Over the previous decade, the program has funded more than 500 projects for local first responders and emergency personnel.

## 5 Meter Reading Technology

Our advanced meter reading technology allows for accurate data collection, enhances customer satisfaction by eliminating the need to enter yards and improves productivity by allowing a single employee in a vehicle to read up to 10,000 meters per day.

## 6 Technology-Driven Initiatives

We will use technology to give customers more choices and personalized services. Solutions will include a new website, automated phone system and enhanced tools for call center agents, all designed to give customers the best possible experience each time they interact with us.



## 2013 Highlights

Added 33,000 customers primarily in the Minneapolis area and several parts of Texas

Replaced half of the cast iron pipe in our system and nearly a third of the bare steel pipe since 2003
Finished in the top quartile of the South and Midwest regions in the J.D. Power and Associates 2013 Gas Utility Residential Customer Satisfaction Study \( ^{SM} \) 

Recorded more than $11 million in conservation improvement program rebates
Grew sales volumes in Energy Services to more than 600 Bcf

Plan to invest more than $520 million in capital in 2014 on system integrity, growth and technology to improve customer service

## Electric Transmission & Distribution

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

## Electric Transmission

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



## Electric Distribution

In the Electric Reliability Council of Texas, Inc. (ERCOT), end users purchase their electricity directly from certificated REPs. CenterPoint Houston delivers electricity for REPs in its certificated service area by carrying lower-voltage power from the substation to the retail electric customer. CenterPoint Houston's distribution network receives electricity from the transmission grid through power distribution substations and delivers electricity to end users through distribution feeders. CenterPoint Houston's operations include construction and maintenance of distribution facilities, metering services, outage response services and call center operations. CenterPoint Houston provides distribution services under tariffs approved by the Texas Utility Commission. Texas Utility Commission 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 Texas Utility Commission.

## ERCOT Market Framework

CenterPoint Houston 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 CenterPoint Houston, are regulated by the Texas Utility Commission. 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 85% 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 74,000 megawatts (MW) at December 31, 2013. 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 North American Electric Reliability Corporation (NERC) and approved by the Federal Energy Regulatory Commission (FERC). These reliability standards are administered by the Texas Regional Entity (TRE), a functionally independent division of ERCOT. The Texas Utility Commission 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 independent system operator (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. Unlike certain other regional power markets, the ERCOT market is not a centrally dispatched power pool, and the ERCOT ISO does not procure energy on behalf of its members other than to maintain the reliable operations of the transmission system. Members who sell and purchase power are responsible for contracting sales and purchases of power bilaterally. The ERCOT ISO also serves as agent for procuring ancillary services for those members who elect not to provide their own ancillary services.

CenterPoint Houston’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. CenterPoint Houston 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 Texas Utility Commission either through the issuance of securitization bonds or through the implementation of a competition transition charge as a rider to the utility's tariff. CenterPoint Houston's integrated utility business was restructured in accordance with the Texas electric restructuring law and its generating stations were sold to third parties. Ultimately CenterPoint Houston 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 CenterPoint Houston. The transition bonds are repaid through charges imposed on customers in CenterPoint Houston's service territory. As of December 31, 2013, approximately $2.9 billion aggregate principal amount of transition bonds were outstanding.



CenterPoint Houston serves nearly all of the Houston/Galveston metropolitan area. At December 31, 2013, CenterPoint Houston’s customers consisted of approximately 70 REPs, which sell electricity to over two million metered customers in CenterPoint Houston’s certificated service area, and municipalities, electric cooperatives and other distribution companies located outside CenterPoint Houston’s certificated service area. Each REP is licensed by, and must meet minimum creditworthiness criteria established by, the Texas Utility Commission.

Sales to REPs that are affiliates of NRG Energy, Inc. (NRG) represented approximately 38%, 39% and 36% of CenterPoint Houston's transmission and distribution revenues in 2013, 2012 and 2011, respectively. Sales to REPs that are affiliates of Energy Future Holdings Corp. (Energy Future Holdings) represented approximately 10%, 10% and 11% of CenterPoint Houston's transmission and distribution revenues in 2013, 2012 and 2011, respectively. CenterPoint Houston's aggregate billed receivables balance from REPs as of December 31, 2013 was $172 million. Approximately 38%, 8% and 8% of this amount was owed by affiliates of NRG, Just Energy Group, Inc. and Energy Future Holdings, respectively. CenterPoint Houston 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.

## Advanced Metering System and Distribution Grid Automation (Intelligent Grid)

In May 2012, CenterPoint Houston substantially completed the deployment of an advanced metering system (AMS), having installed approximately 2.2 million smart meters. This technology should encourage greater energy conservation by giving Houston-area electric consumers the ability to better monitor and manage their electric use and its cost in near real time. To recover the cost of the AMS, the Texas Utility Commission approved a monthly surcharge payable by REPs, initially over 12 years. For the first 24 months, which began in February 2009, the surcharge for residential customers was $3.24 per month. Beginning in February 2011, the surcharge was reduced to $3.05 per month. In September 2011, the surcharge duration was reduced from 12 years to approximately six years for residential customers and approximately eight years for commercial 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. Please read “– Management’s Discussion and Analysis of Financial Condition and Results of Operations – Liquidity and Capital Resources – Regulatory Matters – CenterPoint Houston.”

CenterPoint Houston is also pursuing deployment of an electric distribution grid automation strategy that involves the implementation of an “Intelligent Grid” (IG) which would provide on-demand data and information about the status of facilities on its system. Although this technology is still in the developmental stage, CenterPoint Houston believes it has the potential to provide an improvement in grid planning, operations, maintenance and customer service for the CenterPoint Houston distribution system. These improvements are expected to result in fewer and shorter outages, better customer service, improved operations costs, improved security and more effective use of our workforce. We expect to include the costs of the deployment in future rate proceedings before the Texas Utility Commission.

In October 2009, the U.S. Department of Energy (DOE) selected CenterPoint Houston for a $200 million grant to help fund its AMS and IG projects. CenterPoint Houston received substantially all of the $200 million of grant funding from the DOE by 2011 and used $150 million of it to accelerate completion of its deployment of advanced meters to 2012, instead of 2014 as originally scheduled. CenterPoint Houston estimates that capital expenditures of approximately $660 million for the installation of the advanced meters and corresponding communication and data management systems were incurred over the advanced meter deployment period. CenterPoint Houston is using the other $50 million from the grant for an initial deployment of an IG that covers approximately 12% of its service territory. This initial deployment is expected to be completed in 2014. It is expected that the capital portion of the IG project subject to partial funding by the DOE will cost approximately $140 million.

## Competition

There are no other electric transmission and distribution utilities in CenterPoint Houston’s service area. In order for another provider of transmission and distribution services to provide such services in CenterPoint Houston’s territory, it would be required to obtain a certificate of convenience and necessity from the Texas Utility Commission 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 CenterPoint Houston’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 CenterPoint Houston’s electric distribution services but has not been a significant factor to date.



## Seasonality

A significant portion of CenterPoint Houston’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, CenterPoint Houston’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 CenterPoint Houston’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 CenterPoint Houston’s transmission and distribution lines have been constructed over lands of others pursuant to easements or along public highways and streets as permitted by law.

All real and tangible properties of CenterPoint Houston, 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, 2013, CenterPoint Houston had approximately $1.9 billion aggregate principal amount of general mortgage bonds outstanding under the General Mortgage, including (a) $290 million held in trust to secure pollution control bonds that are not reflected in our consolidated financial statements because we are both the obligor on the bonds and the current owner of the bonds, (b) approximately $118 million held in trust to secure pollution control bonds for which we are obligated and (c) approximately $183 million held in trust to secure pollution control bonds for which CenterPoint Houston is obligated. Additionally, as of December 31, 2013, CenterPoint Houston had approximately $102 million aggregate principal amount of first mortgage bonds outstanding under the Mortgage. CenterPoint Houston may issue additional general mortgage bonds on the basis of retired bonds, 70% of property additions or cash deposited with the trustee. Approximately $3.9 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, 2013. However, CenterPoint Houston has contractually agreed that it will not issue additional first mortgage bonds, subject to certain exceptions.

Electric Lines - Overhead. As of December 31, 2013, CenterPoint Houston owned 28,113 pole miles of overhead distribution lines and 3,703 circuit miles of overhead transmission lines, including 355 circuit miles operated at 69,000 volts, 2,132 circuit miles operated at 138,000 volts and 1,216 circuit miles operated at 345,000 volts.

Electric Lines - Underground. As of December 31, 2013, CenterPoint Houston owned 21,763 circuit miles of underground distribution lines and 26 circuit miles of underground transmission lines, including 2 circuit miles operated at 69,000 volts and 24 circuit miles operated at 138,000 volts.

Substations. As of December 31, 2013, CenterPoint Houston owned 234 major substation sites having a total installed rated transformer capacity of 54,931 megavolt amperes.

Service Centers. CenterPoint Houston operates 14 regional service centers located on a total of 291 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

CenterPoint Houston holds non-exclusive franchises from the incorporated municipalities in its service territory. In exchange for the payment of fees, these franchises give CenterPoint Houston 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.



CERC Corp.’s natural gas distribution business (Gas Operations) engages in regulated intrastate natural gas sales to, and natural gas transportation for, approximately 3.3 million residential, commercial and industrial customers in Arkansas, Louisiana, Minnesota, Mississippi, Oklahoma and Texas. The largest metropolitan areas served in each state by Gas Operations are Houston, Texas; Minneapolis, Minnesota; Little Rock, Arkansas; Shreveport, Louisiana; Biloxi, Mississippi; and Lawton, Oklahoma. In 2013, approximately 41% of Gas Operations’ total throughput was to residential customers and approximately 59% was to commercial and industrial customers.

The table below reflects the number of natural gas distribution customers by state as of December 31, 2013:

<table><tr><td></td><td>Residential</td><td>Commercial/ Industrial</td><td>Total Customers</td></tr><tr><td>Arkansas</td><td>383,454</td><td>48,323</td><td>431,777</td></tr><tr><td>Louisiana</td><td>231,508</td><td>17,182</td><td>248,690</td></tr><tr><td>Minnesota</td><td>754,575</td><td>68,498</td><td>823,073</td></tr><tr><td>Mississippi</td><td>111,016</td><td>12,585</td><td>123,601</td></tr><tr><td>Oklahoma</td><td>91,582</td><td>10,798</td><td>102,380</td></tr><tr><td>Texas</td><td>1,518,831</td><td>89,714</td><td>1,608,545</td></tr><tr><td>Total Gas Operations</td><td>3,090,966</td><td>247,100</td><td>3,338,066</td></tr></table>

Gas Operations also provides unregulated services in Minnesota consisting of residential appliance repair and maintenance services along with heating, ventilating and air conditioning (HVAC) equipment sales.

The demand for intrastate natural gas sales to residential customers and natural gas sales and transportation for commercial and industrial customers is seasonal. In 2013, approximately 68% of the total throughput of Gas Operations’ business occurred in the first and fourth quarters. These patterns reflect the higher demand for natural gas for heating purposes during those periods.

Supply and Transportation. In 2013, Gas Operations 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 2013 included BP Energy Company/BP Canada Energy Marketing (16.2% of supply volumes), Cargill, Inc. (13.2%), Tenaska Marketing Ventures (10.5%), Kinder Morgan Tejas Pipeline/Kinder Morgan Texas Pipeline (8.1%), Shell Energy North America (7.8%), Sequent Energy Management (4.5%), Conoco Inc. (4.0%), Mieco Inc. (3.4%), Renaissance (2.7%), and Laclede Energy Resources (2.5%). Numerous other suppliers provided the remaining 27.1% of Gas Operations’ natural gas supply requirements. Gas Operations transports its natural gas supplies through various intrastate and interstate pipelines, including those owned by our other subsidiaries, under contracts with remaining terms, including extensions, varying from one to ten years. Gas Operations anticipates that these gas supply and transportation contracts will be renewed or replaced prior to their expiration.

Gas Operations 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 Gas Operations 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.

Gas Operations 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 and may also supplement contracted supplies and storage from time to time with stored liquefied natural gas and propane-air plant production.

Gas Operations owns and operates an underground natural gas storage facility with a capacity of 7.0 billion cubic feet (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 million cubic feet (MMcf). It also owns eight propane-air plants with a total production rate of 180,000 Dekatherms (DTH) per day and on-site storage facilities for 12 million gallons of propane (1.0 Bcf natural gas equivalent). It owns a liquefied natural gas plant



facility with a 12 million-gallon liquefied natural gas storage tank (1.0 Bcf natural gas equivalent) and a production rate of 72,000 DTH per day.

On an ongoing basis, Gas Operations 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.

Gas Operations has entered into various asset management agreements associated with its utility distribution service in Arkansas, Louisiana, Mississippi, Oklahoma and Texas. Generally, these asset management agreements are contracts between Gas Operations and an asset manager that are intended to transfer the working capital obligation and maximize the utilization of the assets. In these agreements, Gas Operations agreed to release transportation and storage capacity to other parties to manage gas storage, supply and delivery arrangements for Gas Operations and to use the released capacity for other purposes when it is not needed for Gas Operations. Gas Operations 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. Gas Operations has received approval from the state regulatory commissions in Arkansas, Louisiana, Mississippi and Oklahoma to retain a share of the asset management agreement proceeds. The agreements have varying terms, the longest of which expires in 2016.

## Assets

As of December 31, 2013, Gas Operations owned approximately 73,000 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 Gas Operations, 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 Gas Operations 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

Gas Operations 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 Gas Operations' facilities and market and sell and/or transport natural gas directly to commercial and industrial customers.

## Energy Services

CERC offers variable and fixed-priced physical natural gas supplies primarily to commercial and industrial customers and electric and gas utilities through CenterPoint Energy Services, Inc. (CES) and its subsidiary, CenterPoint Energy Intrastate Pipelines, LLC (CEIP).

In 2013, CES marketed approximately 600 Bcf of natural gas, related energy services and transportation to approximately 17,500 customers (including approximately 6 Bcf to affiliates) in 21 states. Not included in the 2013 customer count are approximately 8,800 natural gas customers that are served under residential and small commercial choice programs invoiced by their host utility. CES customers vary in size from small commercial customers to large utility companies in the central and eastern regions of the United States.

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 and financial products 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 currently transports natural gas on 47 interstate and intrastate pipelines within states located throughout the central and eastern United States. 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 Value at Risk (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. The CES business optimizes its use of these various tools to minimize its supply costs and does not engage in proprietary or speculative commodity trading. The VaR limit within which CES currently operates, a $4 million maximum, 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 2013, CES' VaR averaged $0.2 million with a high of $0.7 million.

## Assets

CEIP owns and operates approximately 235 miles of intrastate pipeline in Louisiana and Texas and contracts out approximately 2.3 Bcf of storage at its Pierce Junction facility in Texas under long-term leases. 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

On March 14, 2013, CenterPoint Energy entered into a Master Formation Agreement (MFA) with OGE Energy Corp. (OGE) and affiliates of ArcLight Capital Partners, LLC (ArcLight), pursuant to which CenterPoint Energy, OGE and ArcLight agreed to form Enable as a private limited partnership. On May 1, 2013, the parties closed on the formation of Enable pursuant to which Enable became the owner of substantially all of CERC Corp.'s former Interstate Pipelines and Field Services businesses.

As of December 31, 2013, CERC Corp., OGE and ArcLight held approximately 58.3%, 28.5% and 13.2%, respectively, of the limited partner interests in Enable. Enable is equally controlled by CERC Corp. and OGE; each own 50% of the management rights in the general partner of Enable. CERC Corp. and OGE also own a 40% and 60% interest, respectively, in the incentive distribution rights held by the general partner of Enable.

Our investment in Enable is accounted for on an equity basis. Equity earnings associated with CenterPoint Energy’s interest in Enable and equity earnings associated with CenterPoint Energy’s 25.05% interest in Southeast Supply Header, LLC (SESH) are reported under the Midstream Investments segment.

Enable. Enable’s assets and operations are organized into two business 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 service to natural gas producers, utilities and industrial customers.

Enable’s natural gas gathering and processing assets are located in four states and serve natural gas production from shale developments in the Anadarko, Arkoma and Ark-La-Tex basins. Enable also owns an emerging crude oil gathering business in the Bakken shale formation that commenced initial operations in November 2013. Enable’s natural gas transportation and storage assets extend from western Oklahoma and the Texas Panhandle to Alabama and from Louisiana to Illinois.



As of December 31, 2013, Enable’s assets included approximately 11,000 miles of gathering pipelines, 12 major processing plants with approximately 2.1 Bcf/d of processing capacity, approximately 7,900 miles of interstate pipelines (including SESH), approximately 2,300 miles of intrastate pipelines and eight storage facilities comprising 86.5 Bcf of storage capacity.

Enable’s Gathering and Processing segment. Enable provides gathering, processing, treating, compression, dehydration and natural gas liquids (NGL) fractionation for natural gas producers. Six of Enable’s processing plants in the Anadarko basin are interconnected via its large-diameter, rich gas gathering system in western Oklahoma, which spans 18 counties and has approximately 1.2 Bcf/d of processing capacity. Enable refers to this system as its “super-header” system. Enable has configured this system to optimize the flow of natural gas and the utilization of the processing plants connected to it. Enable has made investments to expand the super-header system, including its newest plant located in Custer County, Oklahoma (the McClure Plant) that was placed in service in December 2013. The McClure Plant increased Enable’s natural gas processing capacity in the basin by over 15%, providing an additional 200 MMcf/d of natural gas processing capacity. Enable expects to continue to grow the capacity of the super-header system through the planned addition of another new cryogenic processing plant and related gathering pipelines. The new plant, which will be located in Grady County, Oklahoma (the Bradley plant), will provide an additional 200 MMcf/d of processing capacity and is expected to be completed in the first quarter of 2015.

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. Enable’s primary competitors are master limited partnerships who are active in the regions where it operates. In the process of selling NGLs, Enable competes against other natural gas processors extracting and selling NGLs.

Enable’s Transportation and Storage segment. Enable’s natural gas transportation and storage business segment consists of its interstate pipelines, its intrastate pipelines and its storage assets. Enable provides pipeline takeaway capacity for natural gas producers from supply basins to market hubs and critical natural gas supply for industrial end users and utilities, such as local distribution companies (LDCs) and power generators. Enable’s interstate pipeline system, including SESH, includes approximately 7,900 miles of transportation pipelines and extends from western Oklahoma and the Texas Panhandle to Alabama and from Louisiana to Illinois. Enable’s eight storage facilities in Oklahoma, Louisiana and Illinois have 86.5 Bcf of storage capacity.

Enable generates revenue primarily by charging demand fees pursuant to applicable tariffs for the transportation and storage of natural gas on its system.

Enable’s interstate pipelines compete with other interstate and intrastate pipelines. The principal elements of competition among pipelines are rates, terms of service, and flexibility and reliability of service.

SESH. CenterPoint Southeastern Pipelines Holding, LLC, a wholly owned subsidiary of CERC, owned a 25.05% interest in SESH as of December 31, 2013. SESH owns a 1.0 Bcf per day, 274-mile interstate pipeline that runs from the Perryville Hub in Louisiana to Coden, Alabama. The pipeline was placed into service in the third quarter of 2008. The rates charged by SESH for interstate transportation services are regulated by the FERC.

On May 1, 2013, CenterPoint Energy contributed a 24.95% interest in SESH to Enable. CERC has certain put rights, and Enable has certain call rights, exercisable with respect to the 25.05% interest in SESH retained by CERC, under which CERC would contribute its retained interest in SESH, in exchange for a specified number of limited partner units in Enable and a cash payment, payable either from CERC to Enable or from Enable to CERC, for changes in the value of SESH. Affiliates of Spectra Energy Corp own the remaining 50% interest in SESH.

## REGULATION

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

## Federal Energy Regulatory Commission

The FERC has jurisdiction under the Natural Gas Act and the Natural Gas Policy Act of 1978, 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.

CenterPoint Houston 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 CenterPoint Houston and other utilities within ERCOT. The FERC has designated the NERC as the Electric Reliability Organization (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. CenterPoint Houston 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 CenterPoint Houston is required to make additional expenditures to comply with these standards, it is anticipated that CenterPoint Houston 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 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

CenterPoint Houston conducts its operations pursuant to a certificate of convenience and necessity issued by the Texas Utility Commission that covers its present service area and facilities. The Texas Utility Commission and municipalities have the authority to set the rates and terms of service provided by CenterPoint Houston under cost-of-service rate regulation. CenterPoint Houston holds non-exclusive franchises from the incorporated municipalities in its service territory. In exchange for payment of fees, these franchises give CenterPoint Houston 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.

CenterPoint Houston’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 CenterPoint Houston’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 nuclear decommissioning charge associated with decommissioning the South Texas nuclear generating facility, an energy efficiency cost recovery 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 CenterPoint Houston the same rates and other charges for transmission services.

For a discussion of certain of CenterPoint Houston’s ongoing regulatory proceedings, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Liquidity and Capital Resources — Regulatory Matters — CenterPoint Houston” in Item 7 of Part II of this report, which discussion is incorporated herein by reference.



## State and Local Regulation – Natural Gas Distribution

In almost all communities in which Gas Operations 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. Gas Operations expects to be able to renew expiring franchises. In most cases, franchises to provide natural gas utility services are not exclusive.

Substantially all of Gas Operations is subject to cost-of-service rate regulation by the relevant state public utility commissions and, in Texas, by the Railroad Commission of Texas (Railroad Commission) and those municipalities served by Gas Operations that have retained original jurisdiction. In certain of its jurisdictions, Gas Operations 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.

For a discussion of certain of Gas Operations’ ongoing regulatory proceedings, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Liquidity and Capital Resources — Regulatory Matters — Gas Operations” 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 Pipeline Inspection, Protection, Enforcement and Safety Act of 2006 (2006 Act), which reauthorized the programs adopted under the Pipeline Safety Improvement Act of 2002 (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, the Pipeline and Hazardous Materials Safety Administration (PHMSA) at the Department of Transportation (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 Pipeline Safety, Regulatory Certainty, and Job Creation Act of 2011 (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.

We anticipate that compliance with PHMSA’s regulations, performance of the remediation activities by CERC’s natural gas distribution companies and verification of records on maximum allowable operating pressure will 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 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 Act 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 DOT’s enforcement actions and penalties if we fail to comply with pipeline regulations. Please also see the discussion under “— Midstream Investments — Safety and Health Regulation” below.



## Midstream Investments - Rate and Other Regulation

Federal, state, and local regulation of pipeline gathering and transportation services may affect certain aspects of Enable’s business and the market for its products and services.

## Interstate Natural Gas Pipeline Regulation

Enable’s interstate pipeline systems — EGT, MRT and SESH — are subject to regulation by FERC under the Natural Gas Act of 1938 (NGA) and are considered natural gas companies. Natural gas companies may not charge rates that have been determined to be unjust or unreasonable by the FERC. In addition, the FERC prohibits natural gas companies from unduly preferring or unreasonably discriminating against any person with respect to pipeline rates or terms and conditions of service. Under the NGA, the rates for service on Enable’s interstate facilities must be just and reasonable and not unduly discriminatory. Generally, the maximum filed recourse rates for interstate pipelines are based on the pipeline’s cost of service including recovery of and a return on the pipeline’s actual prudent investment cost. Key determinants in the ratemaking process are costs of providing service, allowed rate of return, volume throughput and contractual capacity commitment assumptions. 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. Tariff changes can only be implemented upon approval by the FERC.

## Market Behavior Rules; Posting and Reporting Requirements

On August 8, 2005, Congress enacted the Energy Policy Act of 2005 (EPAct of 2005). Among other matters, the EPAct of 2005 amended the NGA to add an anti-manipulation provision that makes it unlawful for any entity to engage in prohibited behavior in contravention of rules and regulation to be prescribed by the FERC and, furthermore, provides the FERC with additional civil penalty authority. On January 19, 2006, the FERC issued Order No. 670, a rule implementing the anti-manipulation provisions of the EPAct of 2005. The rules make it unlawful for any entity, directly or indirectly in connection with the purchase or sale of natural gas subject to the jurisdiction of the FERC or the purchase or sale of transportation services subject to the jurisdiction of the FERC, to (1) use or employ any device, scheme or artifice to defraud; (2) to make any untrue statement of material fact or omit to make any such statement necessary to make the statements not misleading; or (3) to engage in any act or practice that operates as a fraud or deceit upon any person. The EPAct of 2005 also amends the NGA and the Natural Gas Policy Act of 1978 (NGPA) to give the FERC authority to impose civil penalties for violations of these statutes and FERC’s regulations, rules, and orders, up to $1 million per day per violation for violations occurring after August 8, 2005. 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 Commodity Futures Trading Commission (CFTC) is directed under the Commodities Exchange Act (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.

## Intrastate Natural Gas Pipeline and Storage Regulation

Enable’s transmission lines are subject to state regulation of rates and terms of service. In Oklahoma, its intrastate pipeline system is subject to regulation by the Oklahoma Corporation Commission. Oklahoma has a non-discriminatory access requirement, which is subject to a complaint-based review. In Illinois, Enable’s intrastate pipeline system is subject to regulation by the Illinois Commerce Commission.

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

Failure to observe the service limitations applicable to transportation services provided under Section 311, failure to comply with the rates approved by FERC for Section 311 service, or failure to comply with the terms and conditions of service established in the pipeline’s FERC-approved Statement of Operating Conditions could result in the assertion of federal NGA jurisdiction by



FERC and/or the imposition of administrative, civil and criminal penalties, as described 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, it 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 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 results of operations and cash flows. In addition, if any of Enable's facilities were found to have provided services or otherwise operated in violation of the NGA or NGPA, this could result in the imposition of civil penalties as well as a requirement to disgorge charges collected for such service in excess of the rate established by the FERC.

States may regulate gathering pipelines. State regulation of gathering facilities generally includes various safety, environmental and, in some circumstances, requirements prohibiting undue discrimination, and in some instances complaint-based rate regulation. Enable’s gathering operations may be subject to ratable take and common purchaser statutes in the states in which they operate. These statutes are designed to prohibit discrimination in favor of one producer over another producer or one source of supply over another source of supply and have the effect of restricting Enable’s right as an owner of gathering facilities to decide with whom it contracts to purchase or transport natural gas.

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. Additional rules and legislation pertaining to these matters are considered or adopted from time to time. We cannot predict what effect, if any, such changes might have on Enable’s operations, but the industry could be required to incur additional capital expenditures and increased costs depending on future legislative and regulatory changes.

## 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 Interstate Commerce Act (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 are to be non-discriminatory or not confer any undue preference upon any shipper. FERC regulations also require interstate common carrier petroleum pipelines to file with the FERC and publicly post tariffs stating their interstate transportation rates and terms and conditions of service. Under the ICA, the FERC or interested persons may challenge existing or changed rates or services. The FERC is authorized to investigate such charges and may suspend the effectiveness of a new rate for up to seven months. A successful rate challenge could result in a common carrier paying refunds together with interest for the period that the rate was in effect. The FERC may also order a pipeline to change its rates, and may require a common carrier to pay shippers reparations for damages sustained for a period up to two years prior to the filing of a complaint.

For some time now, the FERC has been issuing regulatory assurances that necessarily balance the anti-discrimination and undue preference requirements of common carriage with the expectations of investors in new and expanding petroleum pipelines. There is an inherent tension between the requirements imposed upon a common carrier and the need for owners of petroleum pipelines to be able to enter into long-term, firm contracts with shippers willing to make the commitments which underpin such large capital investments. The FERC’s solution has been to allow carriers to hold an “open season” prior to the in-service date of pipeline, during which time interested shippers can make commitments to the proposed pipeline project. Throughout commitments from interested shippers during an open season can be for firm service or for non-firm service. Typically, such an open season is for a 30-day period, must be publicly announced, and culminates in interested parties entering into transportation agreements with the carrier. Under FERC precedent, a carrier typically may reserve up to 90% of available capacity for the provision of firm service to shippers making a commitment. At least 10% of capacity ordinarily is reserved for “walk-up” shippers.



## Midstream Investments - 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 pipeline safety regulations, but natural gas gathering pipelines are subject to the pipeline safety regulations 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 Natural Gas Pipeline Safety Act of 1968 (NGPSA) the DOT, through PHMSA, regulates pipeline safety and integrity. NGL and crude oil pipelines are subject to regulation by PHMSA under the HLPSA 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. PHMSA has developed regulations that require natural gas pipeline operators to implement integrity management programs, including more frequent inspections and other measures to ensure pipeline safety in high consequence areas (HCAs). Although many of Enable’s pipeline facilities fall within a class that is currently not subject to these integrity management requirements, Enable may incur significant costs and liabilities associated with repair, remediation, preventive or mitigating measures associated with its non-exempt pipelines. Additionally, should Enable fail to comply with DOT or comparable state regulations, it could be subject to penalties and fines. If future DOT pipeline integrity management regulations were to require that Enable expand its integrity managements program to currently unregulated pipelines, including gathering lines, its 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 health, safety and the environment. As an owner or operator of natural gas distribution systems, and electric transmission and distribution 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 deemed in non-compliance 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.

In order 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 equipment;

• acquire permits for facility operations;

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

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

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 up and restore sites where hazardous substances have been disposed or otherwise 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 affect 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 different from the amounts we currently anticipate. We try to anticipate future regulatory requirements that might be imposed and plan accordingly to remain in 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, however, 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 all material current environmental and safety laws and regulations that relate to our operations. We believe that we are in substantial compliance with all of these environmental laws and regulations.

## Global Climate Change

In recent years, there has been increasing public debate regarding the potential impact on global climate change by various “greenhouse gases” (GHGs) such as carbon dioxide, a byproduct of burning fossil fuels, and methane, the principal component of the natural gas that we transport and deliver to customers. The United States Congress has, from time to time, considered adopting legislation to reduce emissions of GHGs, and there has been a wide-ranging policy debate, both nationally and internationally, regarding the impact of these gases and possible means for their regulation. Some of the proposals would require industrial sources to meet stringent new standards that would require substantial reductions in carbon emissions. In addition, efforts have been made and continue to be made in the international community toward the adoption of international treaties or protocols that would address global climate change issues. Following a finding by the U.S. Environmental Protection Agency (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 requires a reduction in emissions of GHGs from motor vehicles beginning January 2, 2011. The other regulates emissions of GHGs from certain large stationary sources under the Clean Air Act’s Prevention of Significant Deterioration and Title V programs, commencing when the motor vehicle standards took effect on January 2, 2011. Also, the EPA adopted its “Mandatory Reporting of Greenhouse Gases Rule” that requires the annual calculation and reporting of GHG emissions from natural gas transmission, gathering, processing and distribution systems and electric distribution systems that emit 25,000 metric tons or more of  \( CO_{2} \)  equivalent per year. These additional reporting requirements began in 2012 and we are currently in compliance. These permitting and reporting requirements could lead to further regulation of GHGs by the EPA.

Although the adoption of new legislation is uncertain, action by the EPA to impose new standards and reporting requirements regarding GHG emissions continues. In addition, many states and regions of the United States have begun to regulate GHGs. 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, CenterPoint Houston’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 businesses could be adversely affected through lower gas sales, and Enable’s businesses could experience lower revenues. 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 effect 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 and the operations of Enable 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, 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 continues to adopt amendments to its regulations regarding maximum achievable control technology for stationary internal combustion engines (sometimes referred to as the RICE MACT rule), the most recent being January 14, 2013. On August 29, 2013, the EPA announced that it was reconsidering three issues related to the RICE MACT rule, but the agency has not subsequently issued a rule proposal. Compressors and back up electrical generators used by our Natural Gas Distribution segment are generally compliant. Additional rules are expected to be proposed by the EPA this year for compliance by 2016. We believe, however, that our operations will not be materially adversely affected by such requirements.

In addition, on August 16, 2012, the EPA published final rules that establish new air emission control requirements for natural gas and NGL production, processing and transportation activities, including New Source Performance Standards to address emissions of sulfur dioxide and volatile organic compounds, and National Emission Standards for Hazardous Air Pollutants (NESHAPS) to address hazardous air pollutants frequently associated with gas production and processing activities. The finalized regulations establish specific new requirements for emissions from compressors, controllers, dehydrators, storage tanks, gas processing plants and certain other equipment. The final rules under NESHAPS include maximum achievable control technology standards for “small” glycol dehydrators that are located at major sources of hazardous air pollutants and modifications to the leak detection standards for valves. Compliance with such rules is not expected to result in significant costs that would adversely impact our results of operations.

## Water Discharges

Our operations and the operations of Enable 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 and the operations of Enable generate wastes, including some hazardous wastes, that are subject to the federal Resource Conservation and Recovery Act (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

The Comprehensive Environmental Response, Compensation and Liability Act of 1980, as amended (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

Manufactured Gas Plant Sites. CERC and its predecessors operated manufactured gas plants (MGPs) in the past. In Minnesota, CERC has completed remediation on two sites, other than ongoing monitoring and water treatment. There are five remaining sites in CERC’s Minnesota service territory. CERC believes that it has no liability with respect to two of these sites.

As of December 31, 2013, CERC had recorded a liability of $14 million for remediation of these Minnesota sites. The estimated range of possible remediation costs for the sites CERC believes it has responsibility for was $6 million to $41 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 be dependent upon the number of sites to be remediated, the participation of other potentially responsible parties (PRPs), if any, and the remediation methods used. The Minnesota Public Utilities Commission includes approximately $285,000 annually in rates to fund normal on-going remediation costs. As of December 31, 2013, CERC had collected $6.3 million from insurance companies to be used for future environmental remediation.

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. We and CERC do not expect the ultimate outcome of these investigations will have a material adverse impact on the financial condition, results of operations or cash flows of either us or CERC.

Asbestos. Some facilities owned by us contain or have contained asbestos insulation and other asbestos-containing materials. We or our subsidiaries have been named, along with numerous others, as defendants in lawsuits filed by a number of individuals who claim injury due to exposure to asbestos. Some of the claimants have worked at locations owned by us, but most existing claims relate to facilities previously owned by our subsidiaries. We anticipate that additional claims like those received may be asserted in the future. In 2004, we sold our generating business, to which most of these claims relate, to a company which is now an affiliate of NRG. Under the terms of the arrangements regarding separation of the generating business from us and our sale of that business, ultimate financial responsibility for uninsured losses from claims relating to the generating business has been assumed by the NRG affiliate, but 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 the NRG affiliate. Although their ultimate outcome cannot be predicted at this time, we intend to continue vigorously contesting claims that we do not consider to have merit and do not expect, based on our experience to date, these matters, either individually or in the aggregate, to have a material adverse effect on our financial condition, results of operations or cash flows.

Other Environmental. From time to time we identify the presence of environmental contaminants on property where we conduct or have conducted operations. Other such sites involving contaminants may be identified in the future. We have remediated and expect to continue to remediate identified sites consistent with our legal obligations. From time to time we have received notices from regulatory authorities or others regarding our status as a PRP in connection with sites found to require remediation due to the presence of environmental contaminants. In addition, we have 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, we do not expect, based on our experience to date, these matters, either individually or in the aggregate, to have a material adverse effect on our financial condition, results of operations or cash flows.

## Item 1A. Risk Factors

We are a holding company that conducts all of our business operations through subsidiaries, primarily CenterPoint Houston and CERC. We also own interests in Enable Midstream Partners, LP (Enable), a midstream partnership jointly controlled by CERC Corp. and OGE. 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 Affecting Our Electric Transmission & Distribution Business

A substantial portion of CenterPoint Houston’s receivables is concentrated in a small number of REPs, and any delay or default in payment could adversely affect CenterPoint Houston’s cash flows, financial condition and results of operations.

CenterPoint Houston’s receivables from the distribution of electricity are collected from REPs that supply the electricity CenterPoint Houston distributes to their customers. As of December 31, 2013, CenterPoint Houston did business with approximately 70 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 CenterPoint Houston’s services or could cause them to delay such payments. CenterPoint Houston 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 Texas Utility Commission regulations significantly limit the extent to which CenterPoint Houston can apply normal commercial terms or otherwise seek credit protection from firms desiring to provide retail electric service in its service territory, and CenterPoint Houston thus remains at risk for payments not made prior to the shift to another REP or the provider of last resort. The Texas Utility Commission 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 CenterPoint Houston’s billed receivables from REPs are from affiliates of NRG, Just Energy Group, Inc. (Just Energy Group) and Energy Future Holdings. CenterPoint Houston’s aggregate billed receivables balance from REPs as of December 31, 2013 was $172 million. Approximately 38%, 8% and 8% of this amount was owed by affiliates of NRG, Just Energy Group and Energy Future Holdings, respectively. In the fourth quarter of 2013, Energy Future Holdings publicly disclosed that it had engaged in discussions with certain of its creditors with respect to the capital structure of Energy Future Holdings and its affiliates, including the possibility of a restructuring transaction in bankruptcy. The disclosures do not make clear whether those discussions included or addressed the capital structure of affiliates of Energy Future Holdings that are REPs. Any delay or default in payment by REPs could adversely affect CenterPoint Houston’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 CenterPoint Houston had received from such REP.



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

CenterPoint Houston’s rates are regulated by certain municipalities and the Texas Utility Commission based on an analysis of its invested capital and its expenses in a test year. Thus, the rates that CenterPoint Houston is allowed to charge may not match its expenses at any given time. The regulatory process by which rates are determined may not always result in rates that will produce full recovery of CenterPoint Houston’s costs and enable CenterPoint Houston to earn a reasonable return on its invested capital.

Disruptions at power generation facilities owned by third parties could interrupt CenterPoint Houston’s sales of transmission and distribution services.

CenterPoint Houston transmits and distributes to customers of REPs electric power that the REPs obtain from power generation facilities owned by third parties. CenterPoint Houston does not own or operate any power generation facilities. If power generation is disrupted or if power generation capacity is inadequate, CenterPoint Houston’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.

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

A significant portion of CenterPoint Houston’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, CenterPoint Houston’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.

CenterPoint Houston 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 CenterPoint Houston 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 CenterPoint Houston to higher operating costs and may result in increased capital expenditures. In addition, if CenterPoint Houston were to be found to be in noncompliance with applicable mandatory reliability standards, it could be subject to sanctions, including substantial monetary penalties.

The AMS deployed throughout CenterPoint Houston’s service territory may experience unexpected problems with respect to the timely receipt of accurate metering data.

CenterPoint Houston 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 CenterPoint Houston over a bi-directional communications system installed for that purpose. The AMS integrates equipment and computer software from various vendors in order 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 CenterPoint Houston, 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 CenterPoint Houston's results of operations, financial condition and cash flows.

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 Gas Operations are regulated by certain municipalities and state commissions based on an analysis of its invested capital and its expenses in a test year. Thus, the rates that CERC is allowed to charge may not match its expenses at any given time. The regulatory process in which rates are determined may not always result in rates that will produce full recovery of CERC’s costs and enable CERC to earn a reasonable return on its invested capital.



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.

CERC’s natural gas distribution and energy services businesses 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 Gas Operations, 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) apply downward demand pressure on natural gas consumption 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’s having to provide collateral under its shipping or hedging arrangements or in order 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 in order 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.

The states in which CERC provides regulated local 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.

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 recordkeeping, 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.



## Risk Factors Associated with Our Consolidated Financial Condition

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

As of December 31, 2013, we had $8.4 billion of outstanding indebtedness on a consolidated basis, which includes $3.4 billion of non-recourse transition and system restoration bonds. As of December 31, 2013, approximately $593 million principal amount of this debt is required to be paid through 2016. This amount excludes principal repayments of approximately $1.1 billion on transition and system restoration 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;

• 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;

• market perceptions of our ability to access capital markets on reasonable terms;

- our exposure to GenOn Energy, Inc. (GenOn) (formerly known as RRI Energy, Inc., Reliant Energy, Inc. and Reliant Resources, Inc. (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, 2013, CenterPoint Houston had approximately $1.9 billion aggregate principal amount of general mortgage bonds outstanding under the General Mortgage, including (a) $290 million held in trust to secure pollution control bonds that are not reflected in our consolidated financial statements because we are both the obligor on the bonds and the current owner of the bonds, (b) approximately $118 million held in trust to secure pollution control bonds for which we are obligated and (c) approximately $183 million held in trust to secure pollution control bonds for which CenterPoint Houston is obligated. Additionally, as of December 31, 2013, CenterPoint Houston had approximately $102 million aggregate principal amount of first mortgage bonds outstanding under the Mortgage. CenterPoint Houston may issue additional general mortgage bonds on the basis of retired bonds, 70% of property additions or cash deposited with the trustee. Approximately $3.9 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, 2013. However, CenterPoint Houston 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.

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 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, including Enable, in order to meet our payment obligations. 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 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.

Poor investment performance of the pension plan and factors adversely affecting the calculation of pension liabilities could unfavorably impact our liquidity and results of operations.

We maintain a qualified defined benefit pension plan covering 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 as a result 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 and financial position.

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 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.

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 are subject to stringent and complex laws and regulations pertaining to health, safety and the environment. As an owner or operator of natural gas pipelines and distribution systems, and electric transmission and distribution 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 deemed in non-compliance 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.

In order 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 equipment;

• acquire permits for facility operations;



• modify or replace existing and proposed equipment; and

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

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 up and restore sites where hazardous substances have been disposed or otherwise 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 affect 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, CenterPoint Houston does not have insurance covering its transmission and distribution system, other than substations, because CenterPoint Houston believes it to be cost prohibitive. In the future, CenterPoint Houston may not be able to recover the costs incurred in restoring its transmission and distribution properties following hurricanes or other natural 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, CenterPoint Houston 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.

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

Under some circumstances, we, CenterPoint Houston and CERC could incur liabilities associated with assets and businesses we, CenterPoint Houston and CERC no longer own. These assets and businesses were previously owned by Reliant Energy, Incorporated (Reliant Energy), a predecessor of CenterPoint Houston, 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 Holdings, Inc. (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), that company and its subsidiaries assumed liabilities associated with various assets and businesses Reliant Energy transferred to them. RRI also agreed to indemnify, and cause the applicable transferee subsidiaries to indemnify, us and our subsidiaries, including CenterPoint Houston and CERC, with respect to liabilities associated with the transferred assets and businesses. These indemnity provisions were intended to place sole financial responsibility on RRI and its subsidiaries for all liabilities associated with the current and historical businesses and operations of RRI, regardless of the time those liabilities arose. If RRI (now GenOn) were unable to satisfy a liability that has been so assumed in circumstances in which Reliant Energy and its subsidiaries were not released from the liability in connection with the transfer, we, CenterPoint Houston or CERC could be responsible for satisfying the liability.

Prior to the distribution of our ownership in RRI to our shareholders, CERC had guaranteed certain contractual obligations of what became RRI’s trading subsidiary. When the companies separated, RRI agreed to secure CERC against obligations under the guarantees RRI had been unable to extinguish by the time of separation. Pursuant to such agreement, as amended in December 2007, RRI (now GenOn) agreed to provide to CERC cash or letters of credit as security against CERC’s obligations under its



remaining guarantees for demand charges under certain gas transportation agreements if and to the extent changes in market conditions expose CERC to a risk of loss on those guarantees based on an annual calculation, with any required collateral to be posted each December. The undiscounted maximum potential payout of the demand charges under these transportation contracts, which will be in effect until 2018, was approximately $58 million as of December 31, 2013. Based on market conditions in the fourth quarter of 2013 at the time the most recent annual calculation was made under the agreement, GenOn was not obligated to post any security. If GenOn should fail to perform the contractual obligations, CERC could have to honor its guarantee and, in such event, any collateral then provided as security may be insufficient to satisfy CERC’s obligations.

If GenOn were unable to meet its obligations, it could consider, among various options, restructuring under the bankruptcy laws, in which event GenOn might not honor its indemnification obligations and claims by GenOn’s creditors might be made against us as its former owner.

Reliant Energy and RRI (GenOn’s predecessor) are named as defendants in a number of lawsuits arising out of sales of natural gas in California and other markets. Although these matters relate to the business and operations of GenOn, claims against Reliant Energy have been made on grounds that include liability of Reliant Energy as a controlling shareholder of GenOn’s predecessor. We, CenterPoint Houston or CERC could incur liability if claims in one or more of these lawsuits were successfully asserted against us, CenterPoint Houston or CERC and indemnification from GenOn were determined to be unavailable or if GenOn were unable to satisfy indemnification obligations owed with respect to those claims.

In connection with the organization and capitalization of Texas Genco (now an affiliate of NRG), Reliant Energy and Texas Genco entered into a separation agreement in which Texas Genco assumed liabilities associated with the electric generation assets Reliant Energy transferred to it. Texas Genco also agreed to indemnify, and cause the applicable transferee subsidiaries to indemnify, us and our subsidiaries, including CenterPoint Houston, with respect to liabilities associated with the transferred assets and businesses. In many cases the liabilities assumed were obligations of CenterPoint Houston, and CenterPoint Houston was not released by third parties from these liabilities. The indemnity provisions were intended generally to place sole financial responsibility on Texas Genco and its subsidiaries for all liabilities associated with the current and historical businesses and operations of Texas Genco, regardless of the time those liabilities arose. If Texas Genco (now an affiliate of NRG) were unable to satisfy a liability that had been so assumed or indemnified against, and provided we or Reliant Energy had not been released from the liability in connection with the transfer, CenterPoint Houston could 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.

We or our subsidiaries have been named, along with numerous others, as a defendant in lawsuits filed by a number of individuals who claim injury due to exposure to asbestos. Some of the claimants have worked at locations owned by us, but most existing claims relate to facilities previously owned by our subsidiaries. We anticipate that additional claims like those received may be asserted in the future. Under the terms of the arrangements regarding separation of the generating business from us and our sale of that business to an affiliate of NRG, ultimate financial responsibility for uninsured losses from claims relating to the generating business has been assumed by the NRG affiliate, but 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 the NRG affiliate.

Cyber-attacks, acts of terrorism or other disruptions could adversely impact our results of operations, financial condition and cash flows or the results of operations, financial condition and cash flows of Enable.

We and Enable are subject to cyber-security risks related to breaches in the systems and technology used (i) to manage operations and other business processes and (ii) to 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. As we deploy smart meters and the intelligent grid, reliance on communication between and among those components increases. Similarly, the distribution of natural gas to our customers and the gathering, processing and transportation of natural gas or other commodities from Enable's gathering, processing and pipeline facilities, are dependent on communications among Enable's facilities and with third-party systems that may be delivering natural gas or other commodities into or receiving natural gas 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 ability or Enable's ability to conduct operations and control assets. Cyber-attacks could also result in the loss of confidential or proprietary data or security breaches of other information technology systems that could disrupt operations and critical business functions, adversely affect reputation, 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, electrical distribution and transmission facilities and gas distribution and pipeline systems may be targets of terrorist activities that could disrupt either our or Enable’s ability to conduct our respective businesses and have a material adverse effect on either our or Enable’s results of operations, financial condition and cash flows.

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 system failures; and

- catastrophic events such as fires, earthquakes, explosions, floods, droughts, hurricanes, 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 merger and acquisition activities may not be successful or may result in completed acquisitions that do not perform as anticipated.

From time to time, we have made and may continue to make acquisitions of businesses and assets. However, suitable acquisition candidates may not continue to be available on terms and conditions we find acceptable. In addition, 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 may assume liabilities that were not disclosed to us, that exceed our estimates, or for which our rights to indemnification from the seller are limited;

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

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

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 for contractors to replace employees, productivity costs and safety costs, may rise. Failure to hire and adequately train replacement employees, including the transfer of significant internal historical knowledge and expertise to the new employees, or the future availability and cost of contract labor may adversely affect 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.

The United States Congress has from time to time considered adopting legislation to reduce emissions of GHGs, and there has been a wide-ranging policy debate, both nationally and internationally, regarding the impact of these gases and possible means for their regulation. In addition, efforts have been made and continue to be made in the international community toward the adoption of international treaties or protocols that would address global climate change issues, such as the United Nations Climate Change Conference in Doha, Qatar in 2012. 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. In addition, the EPA expanded its existing GHG emissions reporting requirements to include upstream petroleum and natural gas systems that emit 25,000 metric tons or more of  \( CO_{2} \)  equivalent per year. 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, CenterPoint Houston’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 our gas transmission and field services businesses could experience lower revenues. Another possible 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.

## Additional Risk Factors Affecting Our Interests in Enable Midstream Partners, LP

We hold a substantial limited partnership interest in Enable (58.3% of Enable’s outstanding limited partnership interests as of December 31, 2013), 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. 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 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.

Prior to an initial public offering of Enable, Enable is obligated to distribute 100% of its distributable cash (as such term is defined in its partnership agreement) to its limited partners each fiscal quarter within 45 days following the end of the applicable quarter. Following an initial public offering of Enable, (i) we expect that both CERC Corp. and OGE will hold their limited partnership interests in Enable in the form of both common units and subordinated units, and (ii) Enable is expected to pay a specified minimum quarterly distribution 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 (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 following is initial public offering, 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. The amount of cash Enable can distribute on its 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 and crude oil that it handles;

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

- the volume of natural gas 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;

• 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; and

• other business risks affecting its cash levels.

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

Enable is controlled equally by CERC Corp. and OGE, who each own 50% of the management rights in the general partner of Enable. The general partner of Enable is currently governed by a board made up of an equal number of representatives designated by each of us and OGE and an independent director. In addition, until the completion of Enable's initial public offering, ArcLight will have approval rights over certain material activities of Enable, including material increases in capital expenditures and certain equity issuances, entering into transactions with related parties, and acquiring, pledging or disposing of certain material assets. Following completion of Enable's initial public offering, the board of directors of Enable's general partner is expected to be 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 up to three directors who are independent as defined under the independence standards established by the New York Stock Exchange. Accordingly, we are not able to exercise control over Enable.



## We may not realize the benefits we expect from our interests in Enable.

Enable may under-perform, causing our financial results to differ from our own or the investment community’s expectations. In addition, Enable may not be able to achieve anticipated operational and commercial synergies or realize expected growth opportunities. The success of Enable will in part depend on its ability to integrate the operations of the businesses we contributed to Enable with those contributed by OGE and ArcLight. The integration process may be complex, costly and time-consuming. The potential difficulties of integrating the operations include, among others:

• implementing our business plan for the combined business;

• changes in applicable laws and regulations or conditions imposed by regulators;

• retaining key employees;

• operating risks inherent in the contributed businesses;

• realizing growth, revenue and expense targets; and

• unanticipated issues, costs, obligations and liabilities.

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. Conflicts of interest may arise between us and Enable and its unitholders. 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.

Enable generates a substantial portion of its gross margins under long-term, fee-based agreements. As these and other contracts expire, Enable may have to negotiate extensions or renewals with existing suppliers and customers or enter into new contracts with other suppliers and customers. Enable may be unable to obtain new contracts on favorable commercial terms, if at all. It also may be unable to maintain the economic structure of a particular contract with an existing customer or the overall mix of its contract portfolio. For example, depending on prevailing market conditions at the time of a contract renewal, gathering and processing customers with fixed-fee or fixed-margin contracts may desire to enter into contracts under different fee arrangements. To the extent Enable is unable to renew its existing contracts on terms that are favorable to it, if at all, or successfully manage its overall contract mix over time, its revenue, results of operations and distributable cash flow could be adversely affected.

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

Enable provides firm transportation and storage services to certain key customers on its system. Its major transportation customers are affiliates of CenterPoint Energy, Laclede Group (Laclede), OGE, American Electric Power Company, Inc. (AEP) and Exxon Mobil Corporation (Exxon). Enable’s interstate transportation and storage assets were designed and built to serve affiliates of CenterPoint Energy, Laclede, OGE and AEP.

Enable-Mississippi River Transmission, LLC’s (MRT) firm transportation and storage contracts with Laclede are scheduled to expire in 2015 and 2016. The primary terms of Enable Gas Transmission, LLC’s (EGT) firm transportation and storage contracts with CERC’s natural gas distribution business will expire in 2018.

Enable’s firm transportation contract with an affiliate of AEP expires January 1, 2015 and will remain in effect from year to year thereafter unless either party provides written notice of termination to the other party at least 180 days prior to the commencement of the succeeding annual period. The stated term of the OG&E transportation and storage contract expired April 30, 2009, but the contract remained in effect from year to year thereafter. On January 31, 2014, OG&E provided written notice of termination of the contract, effective April 30, 2014. Negotiations regarding the new contract are ongoing, and there can be no



assurance that the new contract will be agreed upon, or, if agreed upon, that the terms of the new contract will be as favorable to Enable as the expiring contract.

The loss of all or even a portion of the interstate or intrastate 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 consolidated financial position, results of operations and its 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 continued availability of natural gas and crude oil production. Enable has no control over the level of drilling activity in its areas of operation, the amount of reserves associated with wells connected to its systems or the rate at which production from a well declines. In addition, Enable’s cash flows associated with wells currently connected to its systems will decline over time. 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 and crude oil supplies. The primary factors affecting Enable’s ability to obtain new supplies of natural gas and crude oil and attract new customers to its assets are the level of successful drilling activity near these systems, its ability to compete for volumes from successful new wells and its ability to expand capacity as needed. If Enable is not able to obtain new supplies of natural gas 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 have a material adverse effect on its results of operations and distributable cash flow. 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 and crude oil reserves. Drilling and production activity generally decreases as commodity prices decrease. In general terms, the prices of natural gas, 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 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 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. A sustained decline 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 have a material adverse effect on its business, financial condition, results of operations and ability to make cash distributions.

In addition, it may be more difficult to maintain or increase the current volumes on Enable’s gathering systems, as several of the formations in the unconventional resource basins 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 have a material adverse effect on its results of operations and distributable cash flow.



Enable’s industry is highly competitive, and increased competitive pressure could adversely affect its results of operations and distributable cash flow.

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 crude oil, natural gas and petrochemical 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 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 transportation services. All of these competitive pressures could adversely affect Enable’s results of operations and distributable cash flow.

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 extensive investment in capital improvements and additions. 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 results of operations and its ability to make cash distributions.

In connection with Enable’s capital investments, Enable may 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 results of operations and its 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 results of operations and its 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 results of operations and its ability to make cash distributions.

Enable’s results of operations and its 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 its 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.

Enable’s keep-whole natural gas processing arrangements expose it to fluctuations in the pricing spreads between NGL prices and natural gas prices. Under these arrangements, the processor processes raw natural gas to extract NGLs and pays to the producer the natural gas equivalent Btu value of raw natural gas received from the producer in the form of either processed natural gas or its cash equivalent. The processor is generally entitled to retain the processed NGLs and to sell them for its own account. Accordingly, the processor’s margin is a function of the difference between the value of the NGLs produced and the cost of the processed natural gas used to replace the natural gas equivalent Btu value of those NGLs. Therefore, if natural gas prices increase and NGL prices do not increase by a corresponding amount, the processor has to replace the Btu of natural gas at higher prices and processing margins are negatively affected.

Under Enable’s percent-of-proceeds and percent-of-liquids natural gas processing agreements, the processor generally gathers raw natural gas from producers at the wellhead, transports the natural gas through its gathering system, processes the natural gas and sells the processed natural gas and/or NGLs at prices based on published index prices. The price paid to producers is based on an agreed percentage of the actual proceeds of the sale of processed natural gas, NGLs or both, or the expected proceeds based on an index price. These arrangements expose Enable to risks associated with the price of natural gas and NGLs.

At any given time, Enable’s overall portfolio of processing contracts may reflect a net short position in natural gas (meaning that it is a net buyer of natural gas) and a net long position in NGLs (meaning that it 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 has limited experience in the crude oil gathering business.

In November 2013, Enable commenced initial operations on a new crude oil gathering pipeline system in North Dakota’s Bakken shale formation, and Enable expects to place additional related assets in service in 2014. The gathering system, located in Dunn and McKenzie Counties in North Dakota, has a planned capacity of up to 19,500 barrels per day. These facilities are the first crude oil gathering system that Enable has built and operated. Other operators of gathering systems in the Bakken shale formation may have more experience in the construction, operation and maintenance of crude oil gathering systems than Enable. This relative lack of experience may hinder Enable’s ability to fully implement its business plan in a timely and cost efficient manner, which, in turn, may adversely affect its results of operations and its ability to make cash distributions.

Enable provides certain transportation and storage services under long-term, 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.

“Negotiated rate” 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 results of operations and its ability to make cash distributions could be adversely affected.

Enable depends upon third-party natural gas pipelines to deliver natural gas to, and take natural gas from, its transportation systems. Enable also depends on third-party facilities to transport and fractionate NGLs that are delivered to the third party at the tailgates of the 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 a prolonged outage or disruption could ultimately result in a reduction in the volume of NGLs Enable 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 results of operations and its ability to make cash distributions to unitholders 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 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 have a material adverse effect on the success of these operations and Enable’s financial position and results of operations.

Enable conducts a portion of its operations through joint ventures with third parties, including affiliates of Spectra Energy Corp, 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. For example, Enable’s joint venture partners may share certain approval rights over major decisions or be in a position to take actions contrary to Enable’s instructions or requests or contrary to its policies or objectives.

These risks or the failure to continue Enable’s joint ventures or to resolve disagreements with Enable’s joint venture partners could adversely affect Enable’s ability to transact the business that is the subject of such joint venture, which would in turn negatively affect Enable’s financial condition and results of operations.

Enable’s business involves many hazards and operational risks, some of which may not be fully covered by insurance. Insufficient insurance coverage and increased insurance costs could adversely impact its results of operations and its ability to make cash distributions.

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

• ruptures, fires and explosions; and

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

These risks could result in substantial losses due to personal injury 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 its operations. Enable is not fully insured against all risks inherent in its business. We and OGE currently have general liability and property insurance in place to cover certain of Enable’s facilities in amounts that we consider appropriate. Such policies are subject to certain limits and deductibles. 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.

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 following its initial public offering. 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.

If Enable does not make acquisitions or is unable to make acquisitions on economically acceptable terms, its future growth will be limited.

Enable’s ability to grow depends, in part, on its ability to make acquisitions that result in an increase in its cash generated from operations. If Enable is unable to make accretive acquisitions either because: (i) it is unable to identify attractive acquisition targets or it is unable to negotiate purchase contracts on acceptable terms, (ii) it is unable to obtain acquisition financing on economically acceptable terms, or (iii) it is outbid by competitors, then its future growth and ability to increase distributions will be limited.

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

As of December 31, 2013, Enable had approximately $1.9 billion of long-term debt outstanding and $200 million of short-term debt outstanding, excluding the premiums on senior notes. Enable has $363 million of long-term notes payable-affiliated companies due to CenterPoint Energy. Enable has a $1.4 billion revolving credit facility for working capital, capital expenditures and other partnership purposes, including acquisitions, of which $1.1 billion was available as of December 31, 2013. As of January 2014, Enable has the ability to issue up to $1.4 billion in commercial paper, subject to available borrowing capacity under its revolving credit facility and market conditions. 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;

- 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 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 business, financial condition, results of operations and ability to make quarterly 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.

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 results of operations and its 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. There are significant capital, operating and other costs associated with compliance with these environmental statutes, rules and regulations and those costs may be even more significant in the future.

There is inherent risk of the incurrence of environmental costs and liabilities in Enable’s operations due to its handling of natural gas, NGLs and crude oil, air emissions related to its operations and historical industry operations and waste disposal practices. These activities 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 results of operations and ability to make cash distributions.

Hydraulic fracturing is an important and common practice that is used to stimulate production of natural gas and/or 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. Many of Enable's customers commonly use hydraulic fracturing techniques in their drilling and completion programs. Hydraulic fracturing typically is regulated by state oil and natural gas commissions. In addition, Congress from time to time has considered the adoption of legislation to provide for federal regulation of hydraulic fracturing under the Safe Drinking Water Act (SDWA) and to require disclosure of the chemicals used in the hydraulic fracturing process. 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. 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.

In addition, certain governmental reviews have been conducted or are underway that focus on environmental aspects of hydraulic fracturing practices. The EPA has commenced a study of the potential environmental effects of hydraulic fracturing on drinking water and groundwater. A draft final report drawing conclusions about the potential impacts of hydraulic fracturing on drinking water resources is currently expected to be available for public comment and peer review in 2014. Moreover, the EPA has announced that it will develop effluent limitations for the treatment and discharge of wastewater resulting from hydraulic fracturing activities by 2014. Other governmental agencies, including the U.S. Department of Energy and the U.S. Department of the Interior, have evaluated or are evaluating various other aspects of hydraulic fracturing. President Obama created the Interagency Working Group on Unconventional Natural Gas and Oil by Executive Order on April 13, 2012, which is charged with coordinating and aligning federal agency research and scientific studies on unconventional natural gas and oil resources, including hydraulic fracturing. These ongoing or proposed studies, depending on their degree of pursuit and any meaningful results obtained, could spur initiatives to further regulate hydraulic fracturing under the SDWA or other regulatory mechanisms.

Enable’s operations are subject to extensive regulation by federal regulatory authorities. Changes or additional regulatory measures adopted by such authorities could have a material adverse effect on Enable’s 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. 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 condition, results of operations and cash flows and its ability to make cash distributions.

Enable’s natural gas interstate pipelines are regulated by the FERC under the Natural Gas Act of 1938, or NGA, the Natural Gas Policy Act of 1978, or the NGPA, and the Energy Policy Act of 2005, or EPAct of 2005. Generally, the FERC’s authority over interstate natural gas transportation extends to:

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

• certification and construction of new facilities;

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

• maintenance of accounts and records;

• acquisition and disposition of facilities;



• initiation and discontinuation of services;

• depreciation and amortization policies;

• conduct and relationship with certain affiliates;

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

• various other matters.

The FERC’s jurisdiction extends to the certification and construction of interstate transportation and storage facilities, including, but not limited to expansions, lateral and other facilities and abandonment of facilities and services. Prior to commencing construction of significant new interstate transportation and storage facilities, an interstate pipeline must obtain a certificate authorizing the construction, or an order amending its existing certificate, from the FERC. Certain minor expansions are authorized by blanket certificates that the FERC has issued by rule. Typically, a significant expansion project requires review by a number of governmental agencies, including state and local agencies, whose cooperation is important in completing the regulatory process on schedule. Any failure by an agency to issue sufficient authorizations or permits in a timely manner for one or more of these projects may mean that Enable will not be able to pursue these projects or that they will be constructed in a manner or with capital requirements that Enable did not anticipate. Enable’s inability to obtain sufficient permits and authorizations in a timely manner could materially and negatively impact the additional revenues expected from these projects.

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

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

Enable’s crude oil gathering pipelines are subject to common carrier regulation by the FERC under the Interstate Commerce Act, or ICA. The ICA requires that Enable maintain tariffs on file with the FERC setting forth the rates it charges for providing transportation services, as well as the rules and regulations governing such services. The ICA requires, among other things, that Enable’s rates must be “just and reasonable” and that it provides service in a manner that is nondiscriminatory.

Enable’s operations may also be subject to regulation by state and local regulatory authorities. Changes or additional regulatory measures adopted by such authorities could adversely affect its results of operations and its ability to make cash distributions.

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. State and local regulations generally focus on safety, environmental and, in some circumstances, prohibition of undue discrimination among shippers. Additional rules and legislation pertaining to these matters are considered and, in some instances, adopted from time to time. We cannot predict what effect, if any, such changes might have on Enable’s operations, but Enable could be required to incur additional capital expenditures and increased costs depending on future legislative and regulatory changes. Other state and local regulations also may affect Enable’s business. Any such state or local regulation could have an adverse effect on its business and the results of its operations.

Enable’s gathering lines may be subject to ratable take and common purchaser statutes. Ratable take statutes generally require gatherers to take, without undue discrimination, oil or natural gas production that may be tendered to the gatherer for handling. Similarly, common purchaser statutes generally require gatherers to purchase without undue discrimination as to source of supply or producer. These statutes restrict Enable’s right as an owner of gathering facilities to decide with whom it contracts to purchase or transport oil or natural gas. Federal law leaves economic regulation of natural gas gathering to the states. The states in which



Enable operates have adopted complaint-based regulation of oil and natural gas gathering activities, which allows oil and natural gas producers and shippers to file complaints with state regulators in an effort to resolve grievances relating to access to oil and natural gas gathering pipelines and rate discrimination.

Other state regulations may not directly regulate Enable’s business, but may nonetheless affect the availability of natural gas for processing, including state regulation of production rates and maximum daily production allowable from gas wells. While Enable’s gathering lines are currently subject to limited state regulation, there is a risk that state laws will be changed, which may give producers a stronger basis to challenge the regulatory status of a line, or the rates, terms and conditions of a gathering line providing transportation service.

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 believe 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 cash flows and its 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 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.

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 operators, including Enable, to, among other things:

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

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

• improve data collection, integration, and analysis;

• repair and remediate pipelines as necessary; and

• implement preventive and mitigating action.



Although many of Enable’s pipelines fall within a class that is currently not subject to these requirements, it may incur significant cost and liabilities associated with repair, remediation, preventive or mitigation measures associated with its non-exempt pipelines. Should Enable fail to comply with DOT or comparable state regulations, it could be subject to penalties and fines. Also, the scope of the integrity management program and other related pipeline safety programs could be expanded in the future.

## Item 7. 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.

## OVERVIEW

## Background

We are a public utility holding company. Our operating subsidiaries own and operate electric transmission and distribution facilities and natural gas distribution facilities and own interests in Enable Midstream Partners, LP (Enable) as described below. Our indirect wholly owned subsidiaries include:

- CenterPoint Energy Houston Electric, LLC (CenterPoint Houston), which engages in the electric transmission and distribution business in a 5,000-square mile area of the Texas Gulf Coast that includes the city of Houston; and

- CenterPoint Energy Resources Corp. (CERC Corp. and, together with its subsidiaries, CERC), which owns and operates natural gas distribution systems in six states (Gas Operations). A wholly owned subsidiary of CERC Corp. offers variable and fixed-price physical natural gas supplies primarily to commercial and industrial customers and electric and gas utilities. As of December 31, 2013, CERC Corp. also owned approximately 58.3% of the limited partner interests in Enable, an unconsolidated partnership jointly controlled with OGE Energy Corp., which owns, operates and develops natural gas and crude oil infrastructure assets.

## 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 certain 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. Our natural gas distribution services are also subject to rate regulation and are reported in the Natural Gas Distribution business 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 that Enable gathers, processes and transports across its systems and other factors as discussed below under “- Factors Influencing Our Midstream Investments Segment.” A summary of our reportable business segments as of December 31, 2013 is set forth below:

## Electric Transmission & Distribution

Our electric transmission and distribution operations provide electric transmission and distribution services to retail electric providers (REPs) serving over two million metered customers in a 5,000-square-mile area of the Texas Gulf Coast that has a population of approximately six million people and includes the city of Houston.

On behalf of REPs, CenterPoint Houston delivers electricity from power plants to substations, from one substation to another and to retail electric customers in locations throughout CenterPoint Houston’s certificated service territory. The Electric Reliability Council of Texas, Inc. (ERCOT) serves as the regional reliability coordinating council for member electric power systems in 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 represents approximately 85% of the demand for power in Texas and is one of the nation’s largest power markets. Transmission and distribution services are provided under tariffs approved by the Public Utility Commission of Texas (Texas Utility Commission).

## Natural Gas Distribution

CERC owns and operates our regulated natural gas distribution business (Gas Operations), which engages in intrastate natural gas sales to, and natural gas transportation for, approximately 3.3 million residential, commercial and industrial customers in Arkansas, Louisiana, Minnesota, Mississippi, Oklahoma and Texas.



CERC’s operations also include non-rate regulated natural gas sales to, and transportation services for, commercial and industrial customers in 21 states in the central and eastern regions of the United States.

## Midstream Investments

We have a significant equity investment in Enable, an unconsolidated subsidiary that owns, operates and develops natural gas and crude oil assets. Our Midstream Investments segment includes equity earnings associated with the operations of Enable and a 25.05% interest in SESH currently owned by CERC.

## Other Operations

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.

## EXECUTIVE SUMMARY

## Factors Influencing Our Businesses

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, 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. Reduced demand and lower energy prices could lead to financial pressure on some of our customers who operate within the energy industry. 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.

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. The Houston area experienced extremely hot and dry weather during 2011. In 2012, we experienced a return to more normal weather in the summer months. However, every state in which we distribute natural gas had the warmest winter on record. In 2013, we experienced a colder than normal spring and very cold weather in November and December in Houston and all of the states in which we have gas customers. In recent years, customers have typically 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 addition, in many of our service areas, particularly in the Houston area and in Minnesota, we have benefited from a growth in the number of customers that also tends to mitigate the effects of reduced consumption. We anticipate that this trend will continue as the regions' economies resume typical growth. 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 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 in the central and eastern regions of the 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 hedge its exposure to price movements, it does not engage in speculative or proprietary trading and maintains a low value at risk level, or VaR, to avoid significant financial exposures. Lower geographic and seasonal price differentials during 2013, 2012 and 2011 adversely affected results for this business segment.

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 in order 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.

We expect to make contributions to our pension plan aggregating approximately $87 million in 2014 and 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 our Gas Operations in Texas.

## Factors Influencing Our Midstream Investments Segment

The results of our Midstream Investments segment are primarily dependent upon the results of Enable, which are driven primarily by the volume of natural gas that Enable gathers, processes and transports across its systems, which depends significantly on the level of production from natural gas wells connected to its systems. Aggregate production volumes are affected by the overall amount of drilling and completion activity, as production must be maintained or increased by new drilling or other activity, because the production rate of a natural gas well declines over time. Producers' willingness to engage in new drilling is determined by a number of factors, the most important of which are the prevailing and projected prices of natural gas and NGLs, the cost to drill and operate a well, the availability and cost of capital and environmental and government regulations. The level of drilling is expected to positively correlate with long-term trends in commodity prices. Similarly, production levels nationally and regionally generally tend to positively correlate with drilling activity.

To maintain and increase gathering throughput volumes on its systems, Enable must continue to contract its capacity to shippers, including producers and marketers. Enable’s transportation and storage systems compete for customers based on the type of service a customer needs, operating flexibility, receipt and delivery points and geographic flexibility and available capacity and price. To maintain and increase Enable’s transportation and storage volumes, it must continue to contract its capacity to shippers, including producers, marketers, LDCs, power generators and end-users.

Enable’s operation and maintenance expenses are comprised primarily of labor expenses, lease costs, utility costs, insurance premiums and repairs and maintenance expenses. These expenses generally remain relatively stable across broad ranges of throughput volumes but can fluctuate from period to period depending on the mix of activities performed during that period and the timing of these expenses. The current high levels of crude oil exploration, development and production activities are increasing competition for personnel and equipment. This increased competition is placing upward pressure on the prices Enable pays for labor, supplies and miscellaneous equipment. To the extent Enable is unable to procure necessary services or offset higher costs, its operating results will be negatively affected.

Our Midstream Investments segment currently includes a 25.05% interest in SESH owned by CERC that may be contributed by CERC to Enable in the future, upon exercise of certain put or call rights under which CERC would contribute to Enable CERC’s retained interest in SESH at a price equal to the fair market value of such interest at the time the put right or call right is exercised (which may be no earlier than May 2014 and May 2015 for a 24.95% and a 0.1% interest, respectively). If CERC were to exercise such put right or Enable were to exercise such call right, CERC’s retained interest in SESH would be contributed to Enable in exchange for consideration consisting of a certain number of limited partnership units in Enable (subject to certain antidilution adjustments) for a 24.95% and a 0.1% interest in SESH, respectively, and, subject to certain restrictions, a cash payment, payable either from CERC to Enable or from Enable to CERC for changes in the value of SESH.

## Significant Events

Enable Midstream Partners. On March 14, 2013, we entered into a Master Formation Agreement (MFA) with OGE Energy Corp. (OGE) and affiliates of ArcLight Capital Partners, LLC (ArcLight), pursuant to which we, OGE and ArcLight agreed to form Enable Midstream Partners, LP (Enable) as a private limited partnership. On May 1, 2013, the parties closed on the formation of Enable pursuant to the terms of the MFA. In connection with the closing (i) CenterPoint Energy Resources Corp. (CERC Corp. and, together with its subsidiaries, CERC) converted its direct wholly owned subsidiary, CenterPoint Energy Field Services, LLC, a Delaware limited liability company (CEFS), into a Delaware limited partnership that became Enable, (ii) CERC Corp. contributed to Enable its equity interests in each of CenterPoint Energy Gas Transmission Company, LLC, which has been subsequently renamed Enable Gas Transmission, LLC (EGT), CenterPoint Energy - Mississippi River Transmission, LLC, which has been subsequently renamed Enable Mississippi River Transmission, LLC (MRT), certain of its other midstream subsidiaries, and a 24.95% interest in Southeast Supply Header, LLC (SESH), and (iii) OGE and ArcLight indirectly contributed 100% of the equity interests in Enogex LLC, which has been subsequently renamed Enable Oklahoma Intrastate Transmission, LLC, to Enable. Enable



owns substantially all of our former Interstate Pipelines and Field Services business segments, except for our retained 25.05% interest in SESH.

As of December 31, 2013, CERC Corp., OGE and ArcLight held approximately 58.3%, 28.5% and 13.2%, respectively, of the limited partner interests in Enable. Enable is equally controlled by CERC Corp. and OGE; each own 50% of the management rights in the general partner of Enable. CERC Corp. and OGE also own a 40% and 60% interest, respectively, in the incentive distribution rights held by the general partner of Enable.

On May 1, 2013, Enable (i) entered into a $1.05 billion three-year senior unsecured term loan facility, (ii) repaid $1.05 billion of indebtedness owed to CERC, and (iii) entered into a $1.4 billion senior unsecured revolving credit facility.

As a result of the formation of Enable, we no longer have Interstate Pipelines or Field Services business segments. Enable is an unconsolidated subsidiary which we account for on an equity basis. Equity earnings associated with our interest in Enable and our retained 25.05% interest in SESH are reported under our Midstream Investments segment. For a further description of our reportable business segments, see Note 17 to our consolidated financial statements.

Debt Matters. In March 2013, CenterPoint Energy Houston Electric, LLC (CenterPoint Houston) retired $450 million aggregate principal amount of its 5.70% general mortgage bonds at their maturity.

In April 2013, CERC Corp. retired approximately $365 million aggregate principal amount of its 7.875% senior notes at their maturity. The retirement of senior notes was financed by CERC Corp. with the issuance of commercial paper.

In May 2013, CERC Corp. applied proceeds from Enable’s May 1, 2013 debt repayment of $1.05 billion to the repayment of $357 million aggregate principal amount of its commercial paper and to the May 31, 2013 redemption of $160 million aggregate principal amount of its 5.95% senior notes due January 15, 2014 at 103.419% of their aggregate principal amount.

On August 1, 2013, approximately $92 million aggregate principal amount of pollution control bonds issued on our behalf were redeemed at 101% of their aggregate principal amount. These bonds had an interest rate of 4%, a maturity date of August 1, 2015 and were collateralized by first mortgage bonds of CenterPoint Houston.

On September 9, 2013, our revolving credit facility and the revolving credit facilities of CenterPoint Houston and CERC Corp. were amended to, among other things, (i) reduce the size of the CERC Corp. facility from $950 million to $600 million, (ii) extend the scheduled termination dates of the three facilities from September 9, 2016 to September 9, 2018, and (iii) change the financial covenant in our facility to a covenant that limits our consolidated debt (excluding transition and system restoration bonds) to an amount not to exceed 65% of our consolidated capitalization (subject to a temporary increase to 70% of our consolidated capitalization under certain circumstances described therein).

On October 15, 2013, approximately $59 million aggregate principal amount of pollution control bonds issued on our behalf were redeemed at 101% of their aggregate principal amount. These bonds had an interest rate of 4%, a maturity date of October 15, 2015 and were collateralized by first mortgage bonds of CenterPoint Houston.

In January 2014, approximately $44 million aggregate principal amount of pollution control bonds issued on behalf of CenterPoint Houston were called for redemption on March 3, 2014 at 101% of their principal amount plus accrued interest. The bonds have an interest rate of 4.25%, mature in 2017 and are collateralized by general mortgage bonds of CenterPoint Houston.

In February 2014, notice was given that approximately $56 million aggregate principal amount of pollution control bonds issued on behalf of CenterPoint Houston must be tendered for purchase by CenterPoint Houston on March 3, 2014 at 101% of their principal amount plus accrued interest pursuant to the mandatory tender provisions of the bonds. The bonds have an interest rate of 5.60%, mature in 2027 and are collateralized by general mortgage bonds of CenterPoint Houston. The purchased pollution control bonds will remain outstanding and may be remarketed.

## 2013 Compared to 2012

Net Income. We reported net income of $311 million ($0.72 per diluted share) for 2013 compared to $417 million ($0.97 per diluted share) for the same period in 2012. The decrease in net income of $106 million was primarily due to a $136 million non-cash step acquisition gain related to the acquisition of an additional 50% interest in Waskom in 2012, a $130 million increase in income tax expense discussed below, a $122 million increase in the loss on our indexed debt securities and a $28 million decrease in operating income (discussed below by segment). Operating income in 2012 included a $252 million non-cash goodwill impairment charge. These decreases were partially offset by a $157 million increase in equity earnings of unconsolidated affiliates, a $85 million decrease in interest expense and a $82 million increase in the gain on our marketable securities.

Income Tax Expense. We reported an effective tax rate of 60.2% for 2013 compared to 44.9% for the same period in 2012. Our effective tax rate for 2013 increased by 15.3% primarily as a result of the formation of Enable with deferred tax expense of $225 million related to the book-to-tax basis difference for contributed non-tax deductible goodwill and a tax benefit of $29 million associated with the remeasurement of state deferred taxes at formation. In addition, we recognized a tax benefit of $8 million based on the settlement with the Internal Revenue Service (IRS) of outstanding tax claims for the 2002 and 2003 audit cycles. Our effective tax rate for 2013 was approximately 36.2% excluding the tax effects from the adjustments described above.



Our effective tax rate for 2012 of 44.9% was primarily impacted by an increase in tax expense of $88 million related to the non-tax deductible impairment of goodwill of $252 million and a reduction in tax expense of $28 million for the release of tax reserves settled with the IRS. Our effective tax rate for 2012 was approximately 37% excluding the tax effects from the adjustments described above.

## 2012 Compared to 2011

Net Income. We reported net income of $417 million ($0.97 per diluted share) for 2012 compared to $1.357 billion ($3.17 per diluted share) for the same period in 2011. The decrease in net income of $940 million was primarily due to the resolution in 2011 of the true-up appeal resulting in an after-tax extraordinary gain of $587 million and a $352 million return on the true-up balance, a $260 million decrease in operating income (discussed by segment below), including a $252 million non-cash goodwill impairment charge, and a $106 million increase in the loss on our indexed debt securities, which were partially offset by a $136 million non-cash step acquisition gain related to the acquisition of an additional 50% interest in Waskom, a $135 million increase in the gain on our marketable securities, a $64 million decrease in income tax expense and a $14 million decrease in interest expense due to lower levels of debt.

Income Tax Expense. We reported an effective tax rate of 44.9% for 2012 compared to 34.4% for the same period in 2011. The increase in the effective tax rate of 10.5% is due to goodwill impairment of $252 million which is non-deductible for tax purposes. It is partially offset by favorable tax adjustments, including the re-measurement of certain unrecognized tax benefits of $28 million related to the Internal Revenue Service (IRS) settlement of tax years 2006 through 2009.

2013 Compared to 2012. Our Electric Transmission & Distribution business segment reported operating income of $607 million for 2013, consisting of $474 million from our regulated electric transmission and distribution utility operations (TDU) and $133 million related to transition and system restoration bond companies. For 2012, operating income totaled $639 million, consisting of $492 million from the TDU and $147 million related to transition and system restoration bond companies. TDU operating income decreased $18 million due to decreased usage ($13 million), primarily due to unfavorable weather, increased taxes other than income taxes ($11 million), increased depreciation ($10 million, excluding $8 million from increased investment in AMS offset by the related revenues), increased labor and benefits costs ($7 million), increased contracts and services ($4 million), increased support services ($4 million) and increased insurance costs ($3 million), partially offset by customer growth ($26 million) from the addition of over 44,000 new customers and higher transmission-related revenues net of the costs billed by transmission providers ($9 million).

2012 Compared to 2011. Our Electric Transmission & Distribution business segment reported operating income of $639 million for 2012, consisting of $492 million from the TDU and $147 million related to transition and system restoration bond companies. For 2011, operating income totaled $623 million, consisting of $496 million from the TDU and $127 million related to transition and system restoration bond companies. TDU operating income decreased $4 million due to decreased usage ($54 million), primarily due to a return to more normal summer weather when compared to the previous year, and the impact of the 2010 rate case implemented in September 2011 ($34 million), partially offset by higher equity returns ($28 million) primarily related to true-up proceeds, increased miscellaneous revenues ($24 million), primarily from right-of-way easement grants, customer growth ($24 million) from the addition of over 44,000 new customers and decreased labor and benefits costs ($6 million).



## Natural Gas Distribution

The following table provides summary data of our Natural Gas Distribution business segment for 2013, 2012 and 2011 (in millions, except throughput and customer data):

2013 Compared to 2012. Our Natural Gas Distribution business segment reported operating income of $263 million for 2013 compared to $226 million for 2012. Operating income increased $37 million primarily due to increased usage as a result of colder weather compared to the prior year, partially mitigated by weather hedges and weather normalization adjustments ($29 million), rate increases ($29 million), and increased economic activity across our footprint including the addition of approximately 33,000 residential customers ($7 million). These increases were partially offset by increased operating expenses ($6 million), higher bad debt expense ($5 million), higher depreciation and amortization expense ($12 million) and an increase in taxes ($5 million), primarily attributable to property taxes. Increased expense related to energy efficiency programs ($17 million) and increased expense related to higher gross receipt taxes ($26 million) were offset by a corresponding increase in the related revenues.

2012 Compared to 2011. Our Natural Gas Distribution business segment reported operating income of $226 million for each of 2012 and 2011. Operating income was unchanged despite substantially reduced revenues from near record mild temperatures in the first quarter of 2012 that were partially mitigated by weather hedges and weather normalization adjustments ($21 million), increased depreciation and amortization expense ($7 million) and increased property taxes ($4 million). These adverse impacts were offset by certain reduced operation and maintenance expenses ($5 million), lower bad debt expense ($7 million), the addition of over 22,000 customers ($6 million) and rate increases ($12 million). Decreased expense related to energy efficiency programs ($4 million) and decreased expense related to lower gross receipts taxes ($12 million) were offset by a corresponding reduction in the related revenues.

(1) These numbers do not include approximately 8,800 and 12,700 natural gas customers as of December 31, 2013 and 2012, respectively, that are under residential and small commercial choice programs invoiced by their host utility.

2013 Compared to 2012. Our Energy Services business segment reported operating income of $13 million compared to $2 million for 2012, excluding the goodwill impairment charge discussed below. The increase in operating income of $11 million was primarily due to a $14 million positive impact from mark-to-market accounting for derivatives associated with certain natural gas purchases and sales used to lock in economic margins. A $2 million mark-to-market charge was incurred in 2013 compared to a charge of $16 million for 2012. Energy Services grew both volume and customers in 2013 offsetting the impact of the lower unit margin environment.

2012 Compared to 2011. Our Energy Services business segment reported operating income, excluding the goodwill impairment discussed below, of $2 million for 2012 compared to $6 million for 2011. The decrease in operating income of $4 million was primarily due to a $24 million negative impact of mark-to-market accounting for derivatives associated with certain forward natural gas purchases and sales used to lock in economic margins. 2012 included mark-to-market charges of $16 million compared to an $8 million benefit for the same period of 2011. Substantially offsetting this decrease was a $20 million improvement in operating margins primarily as a result of the termination of uneconomic transportation contracts and an increase in retail sales customers and volumes.

## Goodwill Impairment

A non-cash goodwill impairment charge of $252 million for our Energy Services business segment was recorded in 2012. The adverse wholesale market conditions facing our energy services business, specifically the prospects for continued low geographic and seasonal price differentials for natural gas, led to a reduction in our estimate of the fair value of goodwill associated with this reporting unit.

2013 Compared to 2012. Our Interstate Pipeline business segment reported operating income of $72 million for 2013 compared to $207 million for 2012. Substantially all of this segment was contributed to Enable on May 1, 2013. As a result, 2013 is not comparable to the prior year. Effective May 1, 2013, our equity method investment and related equity income in Enable are included in our Midstream Investments segment.

2012 Compared to 2011. Our Interstate Pipeline business segment reported operating income of $207 million for 2012 compared to $248 million for 2011. Operating income decreased $41 million primarily due to lower margins resulting from a backhaul contract that expired in 2011 ($16 million), as well as the associated reduction in compressor efficiency ($8 million) on the Carthage to Perryville pipeline due to lower volumes, lower off-system transportation revenues ($8 million), lower seasonal and market-sensitive transportation contracts ($7 million) and ancillary services ($7 million). These margin decreases were partially offset by the effects of the 10-year agreement with our natural gas distribution affiliate ($5 million) which we restructured in 2010. Operating income decreases due to higher operations and maintenance expenses ($1 million) and higher depreciation and amortization expenses ($2 million) due to asset additions were offset by lower taxes other than income taxes ($3 million).

Equity Earnings. This business segment recorded equity income of $7 million, $26 million and $21 million for the years ended December 31, 2013, 2012 and 2011, respectively, from its interest in Southeast Supply Header, LLC (SESH), a jointly-owned pipeline. The decrease from the year ended December 31, 2012 to the year ended December 31, 2013 was primarily due to the contribution of a 24.95% interest in SESH to Enable on May 1, 2013. Beginning May 1, 2013, equity earnings related to the interest in SESH contributed to Enable, as well as our remaining 25.05% interest in SESH, are reported as components of equity income in our Midstream Investments segment.

2013 Compared to 2012. Our Field Services business segment reported operating income of $73 million for 2013 compared to $214 million for 2012. Substantially all of this segment was contributed to Enable on May 1, 2013. As a result, 2013 is not comparable to the prior year. Effective May 1, 2013, our equity method investment and related equity income in Enable are included in our Midstream Investments segment.

2012 Compared to 2011. Our Field Services business segment reported operating income of $214 million for 2012 compared to $189 million for 2011. Operating income increased $25 million primarily from increased margins ($36 million) due to gathering projects in the Haynesville shale, including revenues from throughput guarantees, growth in gathering services and retained natural gas volumes, and acquisitions completed during 2012 ($13 million), partially offset by lower commodity prices ($28 million) on sales of retained natural gas. Operating income also increased ($3 million) due to the classification of earnings from the 50% partnership interest in Waskom which we already owned as operating income beginning in August 2012 instead of equity earnings as reported for prior periods, due to our July 31, 2012 purchase of the 50% interest in Waskom that we did not already own. Lower operation and maintenance expenses ($7 million) were partially offset by higher depreciation expense ($6 million).

Equity Earnings. This business segment recorded equity income of $0-, $5 million and $9 million for the years ended December 31, 2013, 2012 and 2011, respectively, from its interest in Waskom. These amounts are included in Equity in earnings of unconsolidated affiliates under the Other Income (Expense) caption in the Statements of Consolidated Income. From August 1, 2012 through April 30, 2013, financial results for Waskom are included in operating income. On May 1, 2013, our 100% investment in Waskom was contributed to Enable.

## Midstream Investments

During the eight months ended December 31, 2013, we reported pre-tax equity income of $173 million from our 58.3% limited partner interest in Enable and $8 million of pre-tax equity income from our 25.05% interest in SESH. Enable’s gathering and processing operations in 2013 were positively impacted by increases in gross margin resulting from acquisitions, higher gathering and processing fixed-fee volumes, higher natural gas prices and increased processing margins, partially offset by a decline in customer volumes, a decline in NGL price spreads between Conway and Mont Belvieu, and the conversion of a processing contract from keep-whole to fixed-fee. Enable’s transportation and storage operations in 2013 were adversely impacted by a decline in gross margins attributable to lower volumes, primarily due to lower price differentials, which negatively impacted margins on ancillary services, a reduction in liquid sales, a reduction to margins on off-system transportation revenues, a decline in interruptible transportation fees, and a reduction to storage demand fees.



Cash distributions received from Enable and SESH were approximately $106 million and $6 million, respectively, during the eight months ended December 31, 2013.

2013 Compared to 2012. Our Other Operations business segment reported an operating loss of $18 million for 2013 compared to operating income of $2 million for 2012. The decrease in operating income of $20 million is primarily related to the costs associated with the formation of Enable ($13 million), higher depreciation expense ($3 million) and higher property taxes ($2 million).

## LIQUIDITY AND CAPITAL RESOURCES

## Historical Cash Flows

The net cash provided by (used in) operating, investing and financing activities for 2013, 2012 and 2011 is as follows (in millions):

<table><tr><td rowspan="2"></td><td colspan="3">Year Ended December 31,</td></tr><tr><td>2013</td><td>2012</td><td>2011</td></tr><tr><td>Cash provided by (used in):</td><td></td><td></td><td></td></tr><tr><td>Operating activities</td><td>$     1,613</td><td>$     1,860</td><td>$     1,888</td></tr><tr><td>Investing activities</td><td>(1,300)</td><td>(1,603)</td><td>(1,206)</td></tr><tr><td>Financing activities</td><td>(751)</td><td>169</td><td>(661)</td></tr></table>

## Cash Provided by Operating Activities

Net cash provided by operating activities decreased $247 million in 2013 compared to 2012 primarily due to decreased operating income ($280 million), excluding the non-cash goodwill impairment charge of $252 million, decreased cash provided by net accounts receivable/payable ($108 million), cash related to gas storage inventory ($43 million), decreased net margin deposits ($37 million), decreased cash from non-trading derivatives ($16 million), increased pension contributions ($9 million) and decreased cash provided by net regulatory assets and liabilities ($5 million), which was partially offset by increased cash provided by fuel cost recovery ($160 million), increased distributions from equity method investments ($91 million) and decreased net tax payments ($11 million).

Net cash provided by operating activities decreased $28 million in 2012 compared to 2011 primarily due to increased net tax payments ($251 million), which was partially offset by increased cash provided by net accounts receivable/payable ($45 million), increased cash provided by net regulatory assets and liabilities ($35 million), increased cash from non-trading derivative ($33 million).



million), increased cash related to gas storage inventory ($25 million), decreased net margin deposits ($19 million) and increased cash provided by fuel cost recovery ($18 million).

## Cash Used in Investing Activities

Net cash used in investing activities decreased $303 million in 2013 compared to 2012 due to decreased cash paid for acquisitions ($360 million) and decreased restricted cash ($30 million) and increased proceeds from sale of marketable securities ($9 million), which were partially offset by increased capital expenditures ($74 million) and cash contributed to Enable ($38 million).

Net cash used in investing activities increased $397 million in 2012 compared to 2011 due to increased cash paid for acquisitions ($360 million) and decreased cash received from the DOE grant ($110 million), which were partially offset by decreased capital expenditures ($91 million).

## Cash Provided by (Used in) Financing Activities

Net cash used in financing activities increased $920 million in 2013 compared to 2012 primarily due to decreased proceeds from long-term debt ($1,445 million) and increased payments of common stock dividends ($9 million), which were partially offset by increased proceeds from commercial paper ($403 million), decreased cash paid for debt retirement ($62 million), increased short-term borrowings ($29 million), decreased payments of long-term debt ($17 million) and decreased debt issuance costs ($13 million).

Net cash provided by financing activities increased $830 million in 2012 compared to 2011 primarily due to increased proceeds from long-term debt ($1,945 million) and decreased debt issuance costs ($8 million), which were partially offset by increased payments of long-term debt ($681 million), increased payments of commercial paper ($387 million), decreased short-term borrowings ($33 million), increased cash paid for debt retirement ($11 million) and increased payments of common stock dividends ($9 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 2014 include the following:

• capital expenditures of approximately $1.4 billion;

• scheduled principal payments on transition and system restoration bonds of $354 million;

- the expected March 2014 purchase and redemption of pollution control bonds aggregating approximately $100 million at 101% of their principal amount;

• pension contributions aggregating approximately $87 million; and

• dividend payments on CenterPoint Energy common stock and interest payments on debt.

We expect that anticipated 2014 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 and additional credit facilities may not, however, be available to us on acceptable terms.



The following table sets forth our capital expenditures for 2013 and estimates of our capital expenditures for currently identified or planned projects for 2014 through 2018 (in millions):

(1) Following the formation of Enable on May 1, 2013, substantially all of the assets of CenterPoint Energy’s former Interstate Pipelines and Field Services business segments are owned by Enable.

Our capital expenditures are expected to be used for investment in infrastructure for our electric transmission and distribution operations and our natural gas distribution operations. These capital expenditures are anticipated to maintain reliability and safety as well as expand our systems through value-added projects.

The following table sets forth estimates of our contractual obligations, including payments due by period (in millions):

(1) 2.0% Zero-Premium Exchangeable Subordinated Notes due 2029 (ZENS) obligations are included in the 2019 and thereafter column at their contingent principal amount as of December 31, 2013 of $763 million. These obligations are exchangeable for cash at any time at the option of the holders for 95% of the current value of the reference shares attributable to each ZENS ($767 million at December 31, 2013), as discussed in Note 10 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, 2013. 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 14(c) to our consolidated financial statements.

(4) In 2014, we expect to make contributions to our qualified pension plan aggregating approximately $87 million. We expect to contribute approximately $9 million and $17 million, respectively, to our non-qualified pension and postretirement benefits plans in 2014.

(5) For a discussion of other commodity commitments, please read Note 14(a) to our consolidated financial statements.



(6) This table does not include estimated future payments for expected future asset retirement obligations. These payments are primarily estimated to be incurred after 2019. We record a separate liability for the fair value of these asset retirement obligations which totaled $134 million as of December 31, 2013. See Note 3(c), Asset Retirement Obligation in our consolidated financial statements.

## Off-Balance Sheet Arrangements

Prior to the distribution of our ownership in Reliant Resources, Inc. (RRI) to our shareholders, CERC had guaranteed certain contractual obligations of what became RRI’s trading subsidiary. When the companies separated, RRI agreed to secure CERC against obligations under the guarantees RRI had been unable to extinguish by the time of separation. Pursuant to such agreement, as amended in December 2007, RRI (now GenOn Energy, Inc. (GenOn)) agreed to provide to CERC cash or letters of credit as security against CERC’s obligations under its remaining guarantees for demand charges under certain gas transportation agreements if and to the extent changes in market conditions expose CERC to a risk of loss on those guarantees based on an annual calculation, with any required collateral to be posted each December. The undiscounted maximum potential payout of the demand charges under these transportation contracts, which will be in effect until 2018, was approximately $58 million as of December 31, 2013. Based on market conditions in the fourth quarter of 2013 at the time the most recent annual calculation was made under the agreement, GenOn was not obligated to post any security. If GenOn should fail to perform the contractual obligations, CERC could have to honor its guarantee and, in such event, any collateral provided as security may be insufficient to satisfy CERC’s obligations.

CenterPoint Energy, Inc. has provided guarantees (CenterPoint Midstream Guarantees) with respect to the performance of certain obligations of Enable under long-term gas gathering and treating agreements with an indirect wholly owned subsidiary of Encana Corporation and an indirect wholly owned subsidiary of Royal Dutch Shell plc. As of December 31, 2013, CenterPoint Energy, Inc. had guaranteed Enable’s obligations up to an aggregate amount of $100 million under these agreements. Under the terms of the omnibus agreement entered into in connection with the closing of the formation of Enable, Enable and CenterPoint Energy, Inc. have agreed to use commercially reasonable efforts and cooperate with each other to terminate the CenterPoint Midstream Guarantees, and to release CenterPoint Energy, Inc. from such guarantees by causing Enable or one of its subsidiaries to enter into substitute guarantees or to assume the CenterPoint Midstream Guarantees as applicable. CERC Corp. has also provided a guarantee of collection of Enable’s obligations under its $1.05 billion three-year unsecured term loan facility, which guarantee is subordinated to all senior debt of CERC Corp.

As of December 31, 2013, no amounts have been recorded related to the guarantees discussed above in the Consolidated Balance Sheets. Other than the guarantees discussed above and operating leases, we have no off-balance sheet arrangements.

## Regulatory Matters

## CenterPoint Houston

In October 2009, the Public Utility Commission of Texas (Texas Utility Commission) issued an order disallowing recovery of a performance bonus of $2 million on approximately $10 million in 2008 energy efficiency costs expended pursuant to the terms of a settlement agreement in a prior rate case. CenterPoint Houston appealed the denial of the full 2008 performance bonus. Similar orders by the Texas Utility Commission providing for the partial disallowance of performance bonuses totaling approximately $5.5 million relating to CenterPoint Houston’s 2009, 2010 and 2011 (only through August 2011) energy efficiency programs were also appealed. These subsequent cases were abated pending the final outcome of the 2008 bonus appeal. In August 2013, the court of appeals reversed the Texas Utility Commission’s decision disallowing such bonuses and the Texas Utility Commission appealed that decision to the Texas Supreme Court in October 2013. In January 2014, the Texas Supreme Court denied the Texas Utility Commission’s appeal. CenterPoint Houston’s energy efficiency programs are no longer funded pursuant to the terms of the prior settlement, and no additional performance bonus disallowances are expected.

In December 2013, CenterPoint Houston filed an application at the Texas Utility Commission seeking (i) to reconcile approximately $473 million in Advanced Metering System costs incurred during the time period April 1, 2010 through September 30, 2013 and currently in rates, and (ii) approval to amend the surcharge recovery period to account for the reconciled costs through September 30, 2013 as well as to recover costs expected to be incurred after September 30, 2013. A decision by the Texas Utility Commission is expected later this year.



## Gas Operations

City of Houston Settlement. In January 2013, the City of Houston initiated a rate proceeding against Gas Operations claiming regulatory disclosures indicated that Gas Operations was earning more on an annual basis than authorized. In February 2014, Gas Operations and City of Houston agreed (i) to terminate the rate proceeding, and (ii) that Gas Operations would not seek a base rate increase before Fall 2016.

Houston and South Texas Gas Reliability Infrastructure Programs (GRIP). The natural gas distribution business of CERC’s (Gas Operations) Houston and South Texas Divisions each submitted annual GRIP filings on March 28, 2013. For the Houston Division, the filing was to recover costs related to $55.8 million in incremental capital expenditures that were incurred in 2012. The increase in revenue requirements for this filing period is $10.7 million annually based on an authorized rate of return of 8.65%. For the South Texas Division, the filing was to recover costs related to $17.5 million in incremental capital expenditures that were incurred in 2012. The increase in revenue requirements for this filing period is $2.9 million annually based on an authorized rate of return of 8.75%. Rates were completely implemented by July 2013.

Arkansas Billing Determinant Rate Adjustment Tariff (BDA) Filing. Gas Operations’ Arkansas Division made its annual BDA filing with the Arkansas Public Service Commission (APSC) on March 27, 2013 to request recovery of a calendar year 2012 shortfall of $6.8 million. No exceptions were noted by the APSC staff and the revised rates went into effect on June 1, 2013.

Mississippi Rate Regulation Adjustment Rider (RRA). Gas Operations’ Mississippi Division submitted an annual RRA filing with the Mississippi Public Service Commission (MPSC) on May 1, 2013 to request recovery of a calendar year 2012 earnings shortfall of approximately $3.2 million. The MPSC approved approximately $2.9 million, and the revised rates went into effect in July 2013.

Cost of Service Adjustment (COSA) Rate Adjustments. In March 2008, Gas Operations filed a request to change its rates with the Railroad Commission of Texas (Railroad Commission) and the 47 cities in its Texas Coast service territory, including a request for an annual cost of service adjustment mechanism, or COSA, that adjusts rates annually for changes in invested capital as well as certain operating expenses. In 2008, the Railroad Commission approved the implementation of rates increasing annual revenues from the Texas Coast service territory by approximately $3.5 million. The approved rates were contested by a coalition of nine cities in an appeal to the 353rd district court in Travis County, Texas. In 2010, the district court ruled that the Railroad Commission lacked authority to impose the approved COSA mechanism both in those nine cities and in those areas in which the Railroad Commission has original jurisdiction. The decision by the District Court placed at risk certain revenues collected pursuant to COSA mechanisms. The Railroad Commission and Gas Operations appealed the court's ruling on the COSA mechanism. In January 2014, the Texas Supreme Court confirmed that the Railroad Commission had authority to approve the COSA rate adjustments utilized by Gas Operations and remanded the case back to state district court.

Minneapolis Franchise. Gas Operations currently provides natural gas distribution services to approximately 124,000 customers in Minneapolis, Minnesota under a franchise that is due to expire at the end of 2014. In June 2013, the Minneapolis City Council (City Council) voted to hold public hearings on August 1, 2013 to consider (i) authorizing the establishment of a municipal electric utility and authorizing the city to own, operate, construct and extend electric facilities and acquire the property of any existing electric public utility operating within Minneapolis, and (ii) authorizing the establishment of a municipal gas utility and authorizing the city to own, operate, construct and extend gas and similar facilities and acquire the property of any existing gas public utility operating within Minneapolis. On August 16, 2013, the City Council voted not to conduct a special election on the question of whether the city should be authorized to establish a municipal utility. Additionally, the City Council directed city staff to begin negotiations with Gas Operations on a franchise renewal and to work to complete the franchise agreement by June 2014.

Minnesota Rate Proceeding. On August 2, 2013, Gas Operations filed a general rate case in Minnesota to increase overall revenue $44.3 million annually, based on a rate base of $700 million and return on equity (ROE) of 10.3%. In compliance with state law, Gas Operations implemented interim rates reflecting $42.9 million dollars of the requested increase for gas used on and after October 1, 2013. Evidentiary hearings were held before an Administrative Law Judge in January 2014, and Gas Operations expects a final decision from the Minnesota Public Utilities Commission in its rate proceeding in mid-summer 2014. This rate filing is intended to recover significant capital expenditures Gas Operations is making in Minnesota and includes moving $15.0 million of energy efficiency expenditures into base rates.



## Enable Midstream Partners

In August 2012, MRT, a subsidiary of Enable and an interstate pipeline that provides natural gas transportation, natural gas storage and pipeline services to customers principally in Arkansas, Illinois and Missouri, made a rate filing with the Federal Energy Regulatory Commission (FERC) pursuant to Section 4 of the Natural Gas Act. In its filing, MRT requested an annual cost of service of $104 million (an increase of approximately $48 million above the annual cost of service underlying the current FERC approved maximum rates for MRT's pipeline), new depreciation rates, an overall rate of return of 10.813% (based on a ROE of 13.62%), a regulatory compliance cost (RCC) surcharge with a true-up mechanism to recover safety, environmental, and security costs associated with mandated requirements and billing determinants reflecting no adjustments for MRT's conversion of a portion of EGT's firm capacity to a lease. On July 30, 2013, MRT filed with the FERC an uncontested Stipulation and Agreement and Offer of Settlement, resolving all issues in the rate case. In particular, MRT withdrew its proposed RCC surcharge. The settlement specifies few particulars, other than setting an annual overall cost-of-service for MRT of $84.0 million and increasing the depreciation rates for certain asset classes. In September 2013, the FERC approved the settlement. Although the settlement became effective November 1, 2013, the settlement rates are effective as of March 1, 2013. As a result, in the fourth quarter of 2013, MRT made refunds to certain of its customers totaling approximately $5.9 million, which had previously been reserved.

## Other Matters

## Credit Facilities

As of February 14, 2014, we had the following facilities (in millions):

<table><tr><td>Date Executed</td><td>Company</td><td>Size of Facility</td><td>Amount Utilized at February 14, 2014 (1)</td><td>Termination Date</td></tr><tr><td>September 9, 2011</td><td>CenterPoint Energy</td><td>$ 1,200</td><td>$ 6</td><td>September 9, 2018</td></tr><tr><td>September 9, 2011</td><td>CenterPoint Houston</td><td>300</td><td>4</td><td>September 9, 2018</td></tr><tr><td>September 9, 2012</td><td>CERC Corp.</td><td>600</td><td>—</td><td>September 9, 2018</td></tr></table>

(1) Based on the consolidated debt to capitalization covenant in our revolving credit facility and the revolving credit facility of each of CenterPoint Houston and CERC Corp., we would have been permitted to utilize the full capacity of such revolving credit facilities, which aggregated $2.1 billion at December 31, 2013.

(2) Represents outstanding letters of credit.

Our $1.2 billion revolving credit facility can be drawn at the London Interbank Offered Rate (LIBOR) plus 125 basis points based on our current credit ratings. The revolving credit facility contains a financial covenant which limits our consolidated debt (excluding transition and system restoration bonds) to an amount not to exceed 65% of our consolidated capitalization. The financial covenant limit will temporarily increase from 65% to 70% if CenterPoint Houston experiences damage from a natural disaster in its service territory and we certify to the administrative agent that CenterPoint Houston has incurred system restoration costs reasonably likely to exceed $100 million in a consecutive twelve-month period, all or part of which CenterPoint Houston intends to seek to recover through securitization financing. Such temporary increase in the financial covenant would be in effect from the date we deliver our certification until the earliest to occur of (i) the completion of the securitization financing, (ii) the first anniversary of our certification or (iii) the revocation of such certification.

CenterPoint Houston’s $300 million revolving credit facility can be drawn at LIBOR plus 112.5 basis points based on CenterPoint Houston’s current credit ratings. The revolving credit facility contains a financial covenant which limits CenterPoint Houston’s consolidated debt (excluding transition and system restoration bonds) to an amount not to exceed 65% of CenterPoint Houston’s consolidated capitalization.

CERC Corp.’s $600 million revolving credit facility can be drawn at LIBOR plus 150 basis points based on CERC Corp.’s current credit ratings. The revolving credit facility contains a financial covenant which limits CERC’s consolidated debt to an amount not to exceed 65% of CERC’s consolidated capitalization.

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.

On April 11, 2013, we amended our revolving credit facility and CERC Corp. amended its revolving credit facility to add exceptions to each borrower’s covenants which restrict (i) the consolidation, merger or disposal of assets and (ii) the sale of stock in certain significant subsidiaries, in each case to permit the transactions contemplated in the formation of Enable.

On September 9, 2013, our revolving credit facility and the revolving credit facilities of CenterPoint Houston and CERC Corp. were amended to, among other things, (i) reduce the size of the CERC Corp. facility from $950 million to $600 million, (ii) extend the scheduled termination dates of the three facilities from September 9, 2016 to September 9, 2018, and (iii) change the financial covenant in our facility to a covenant that limits our consolidated debt (excluding transition and system restoration bonds) to an amount not to exceed 65% of our consolidated capitalization (subject to a temporary increase to 70% of our consolidated capitalization under certain circumstances described therein).

Our $1.2 billion revolving credit facility backstops our $1.0 billion commercial paper program. CERC Corp.'s $600 million revolving credit facility backstops its $600 million commercial paper program. As of December 31, 2013, CERC Corp had $118 million of outstanding commercial paper.

## Securities Registered with the SEC

CenterPoint Energy, CenterPoint Houston and CERC Corp. have filed a joint shelf registration statement with the SEC registering indeterminate principal amounts of CenterPoint Houston’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.

## Temporary Investments

As of February 14, 2014, CERC Corp. had temporary investments in a money market fund of $104 million.

## 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 14, 2014, Moody’s Investors Service, Inc. (Moody’s), Standard & Poor’s Rating Services (S&P), a division of The McGraw-Hill Companies, and Fitch, Inc. (Fitch) had assigned the following credit ratings to senior debt of CenterPoint Energy and certain subsidiaries:

<table><tr><td rowspan="2">Company/Instrument</td><td colspan="2">Moody’s</td><td colspan="2">S&amp;P</td><td colspan="2">Fitch</td></tr><tr><td>Rating</td><td>Outlook (1)</td><td>Rating</td><td>Outlook (2)</td><td>Rating</td><td>Outlook (3)</td></tr><tr><td>CenterPoint Energy Senior Unsecured Debt</td><td>Baa1</td><td>Stable</td><td>BBB+</td><td>Stable</td><td>BBB</td><td>Stable</td></tr><tr><td>CenterPoint Houston Senior Secured Debt</td><td>A1</td><td>Stable</td><td>A</td><td>Stable</td><td>A</td><td>Stable</td></tr><tr><td>CERC Corp. Senior Unsecured Debt</td><td>Baa2</td><td>Stable</td><td>A-</td><td>Stable</td><td>BBB</td><td>Stable</td></tr></table>

(1) A Moody’s rating outlook is an opinion regarding the likely direction of a 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 encompasses a one- to two-year horizon as to the likely ratings direction.



We cannot assure you 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 $1.2 billion revolving credit facility, CenterPoint Houston’s $300 million revolving credit facility and CERC Corp.’s $600 million revolving credit facility. If our credit ratings or those of CenterPoint Houston 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, 2013, 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.

CERC Corp. and its subsidiaries purchase natural gas from one of their suppliers under supply agreements that contain an aggregate credit threshold of $140 million based on CERC Corp.'s S&P senior unsecured long-term debt rating of A-. Under these agreements, CERC may need to provide collateral if the aggregate threshold is exceeded or if the S&P senior unsecured long-term debt rating is downgraded below BBB+.

CenterPoint Energy Services, Inc. (CES), a wholly owned subsidiary of CERC Corp. operating in our Energy Services business segment, provides comprehensive natural gas sales and services primarily to commercial and industrial customers and electric and gas utilities throughout the central and eastern United States. In order 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-to-market exposure in excess of the credit threshold is routinely collateralized by CES. As of December 31, 2013, the amount posted as collateral aggregated approximately $5 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, 2013, unsecured credit limits extended to CES by counterparties aggregate $308 million and $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 $180 million as of December 31, 2013. The amount of collateral will depend on seasonal variations in transportation levels.

In September 1999, we issued Zero-Premium Exchangeable Subordinated Notes due 2029 (ZENS) having an original principal amount of $1.0 billion of which $828 million remains outstanding at December 31, 2013. Each ZENS note 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 Time Warner Inc. common stock (TW Common) attributable to such note. The number and identity of the reference shares attributable to each ZENS note are adjusted for certain corporate events. As of December 31, 2013, the reference shares for each ZENS note consisted of 0.5 share of TW Common, 0.125505 share of Time Warner Cable Inc. (TWC) common stock (TWC Common) and 0.045455 share of AOL Inc. common stock (AOL Common). On February 13, 2014, TWC announced that it had agreed to merge with Comcast Corporation (Comcast). In the merger, each share of TWC Common would be exchanged for 2.875 shares of Comcast common stock (Comcast Common). Upon the closing of the merger (assuming no change in the merger consideration), the reference shares for each ZENS note would include 0.360827 share of Comcast Common in place of the current 0.125505 share of TWC Common. If our creditworthiness were to drop such that ZENS note holders thought our liquidity was adversely affected or the market for the ZENS notes were to become illiquid, some ZENS note holders might decide to exchange their ZENS notes for cash. Funds for the payment of cash upon exchange could be obtained from the sale of the shares of TW Common, TWC Common and AOL Common that we own or from other sources. We own shares of TW Common, TWC Common and AOL Common equal to approximately 100% of the reference shares used to calculate our obligation to the holders of the ZENS notes. ZENS note exchanges result in a cash outflow because tax deferrals related to the ZENS notes and TW Common, TWC Common and AOL Common shares would typically cease when ZENS notes are exchanged or otherwise retired and TW Common, TWC Common and AOL Common shares are sold. The ultimate tax liability related to the ZENS notes 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 notes. If all ZENS notes had been exchanged for cash on December 31, 2013, deferred taxes of approximately $364 million would have been payable in 2013.

## Cross Defaults

Under our revolving credit facility, a payment default on, or a non-payment default that permits acceleration of, any indebtedness exceeding $75 million by us or any of our significant subsidiaries will cause a default. In addition, three outstanding series of our senior notes, aggregating $750 million in principal amount as of December 31, 2013, provide that a payment default by us, CERC Corp. or CenterPoint Houston in respect of, or an acceleration of, borrowed money and certain other specified types of obligations, in the aggregate principal amount of $50 million, 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 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.

## Enable Midstream Partners

In connection with its formation on May 1, 2013, Enable (i) entered into a $1.05 billion 3-year senior unsecured term loan facility, (ii) repaid $1.05 billion of indebtedness owed to CERC Corp., and (iii) entered into a $1.4 billion senior unsecured revolving credit facility. Enable's $1.4 billion senior unsecured revolving credit facility backstops its $1.4 billion commercial paper program. As of January 31, 2014, Enable had no outstanding commercial paper and $318 million borrowed under its revolving credit facility. Any reduction in Enable's credit ratings could prevent it from accessing the commercial paper markets.

The sponsors of Enable, including us, may from time to time provide funds to Enable through loans and/or capital contributions in addition to funds that Enable may obtain from time to time under its revolving credit facility, commercial paper program or from other sources, which loans or capital contributions could be substantial.

Certain of the entities contributed to Enable by CERC Corp. are obligated on approximately $363 million of indebtedness owed to a wholly owned subsidiary of CERC Corp. that is scheduled to mature in 2017.

Prior to an initial public offering of Enable, Enable is obligated to distribute 100% of its distributable cash (as such term is defined in its partnership agreement) to its limited partners each fiscal quarter within 45 days following the end of the applicable quarter. In July 2013, CERC Corp. received a cash distribution of approximately $36 million from Enable made with respect to CERC Corp.'s limited partner interest in Enable for the months of May and June 2013 (the two months in the second quarter following the formation of Enable on May 1, 2013). In November 2013, CERC Corp. received a cash distribution of approximately $70 million from Enable made with respect to CERC Corp.'s limited partner interest in Enable for the third quarter of 2013. CERC Corp. received a cash distribution of approximately $67 million from Enable in February 2014 made with respect to CERC Corp.'s limited partner interest in Enable for the fourth quarter of 2013.

Under the terms of an omnibus agreement entered into in connection with the formation of Enable, CenterPoint Energy and OGE Energy are obligated to indemnify Enable for specified breaches of representations and warranties in the master formation agreement pursuant to which Enable was formed related to: (i) their respective authority to enter into the transactions that formed Enable and the capitalization of the entities contributed to Enable; (ii) permits related to the operation of the assets contributed to Enable; (iii) compliance with environmental laws; (iv) title to properties and rights of way; (v) the tax classification of the entities contributed to Enable; (vi) indemnified taxes; and (vii) events and conditions associated with CenterPoint Energy and OGE's respective ownership and operation of the assets contributed to Enable. Pursuant to the terms of the omnibus agreement, each of CenterPoint Energy's and OGE's respective maximum liability for this indemnification obligation with respect to permit, environmental and title representations will not exceed $250 million, and neither OGE Energy nor CenterPoint Energy will have any obligation under this indemnification until Enable's aggregate indemnifiable losses exceed $25 million, respectively. CenterPoint Energy's and OGE Energy's indemnification obligations under the omnibus agreement will survive (i) for permit matters until May 1, 2014, (ii) for environmental and title and rights of way matters until May 1, 2016 and (iii) for tax classification



matters and indemnified taxes until 30 days following the expiration of the applicable statute of limitations. Indemnification obligations for authority and capitalization matters survive indefinitely.

## Dodd-Frank Swaps Regulation

We use derivative instruments such as physical forward contracts, swaps and options to mitigate the impact of changes in commodity prices and weather on our operating results and cash flows. In addition, Enable may also use such instruments from time to time to manage its commodity and financial market risk. Following enactment of the Dodd-Frank Wall Street Reform and Consumer Protection Act (Dodd-Frank) in July 2010, the Commodity Futures Trading Commission (CFTC) has promulgated regulations to implement Dodd-Frank's changes to the Commodity Exchange Act, including the definition of commodity-based swaps subject to those regulations. The CFTC regulations are intended to implement new reporting and record keeping requirements related to their swap transactions and a mandatory clearing and exchange-execution regime for various types, categories or classes of swaps, subject to certain exemptions, including the trade-option and end-user exemptions. Although we anticipate that most, if not all, of our swap transactions should qualify for an exemption to the clearing and exchange-execution requirements, we will still be subject to record keeping and reporting requirements. Other changes to the Commodity Exchange Act made as a result of Dodd-Frank and the CFTC's implementing regulations could significantly increase the cost of entering into new swaps.

## Collection of Receivables from REPs

CenterPoint Houston’s receivables from the distribution of electricity are collected from REPs that supply the electricity CenterPoint Houston 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 CenterPoint Houston’s services or could cause them to delay such payments. CenterPoint Houston depends on these REPs to remit payments on a timely basis, and any delay or default in payment by REPs could adversely affect CenterPoint Houston’s cash flows. In the event of a REP’s default, CenterPoint Houston’s tariff provides a number of remedies, including the option of CenterPoint Houston to request that the Texas Utility Commission 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, CenterPoint Houston remains at risk for payments not made 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 CenterPoint Houston involving payments it had received from such REP. If a REP were to file for bankruptcy, CenterPoint Houston 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, Texas Utility Commission 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;



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

• the outcome of litigation brought by and 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

CenterPoint Houston’s revolving credit facility limits CenterPoint Houston’s consolidated debt (excluding transition and system restoration bonds) to an amount not to exceed 65% of its consolidated capitalization. CERC Corp.’s revolving credit facility limits CERC’s consolidated debt to an amount not to exceed 65% of its consolidated capitalization. Our revolving credit facility limits our consolidated debt (excluding transition and system restoration bonds) to an amount not to exceed 65% of our consolidated capitalization. The financial covenant limit in our revolving credit facility will temporarily increase from 65% to 70% if CenterPoint Houston experiences damage from a natural disaster in its service territory that meets certain criteria. Additionally, CenterPoint Houston has contractually agreed that it will not issue additional first mortgage bonds, subject to certain exceptions.

## 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. At December 31, 2013, we had recorded regulatory assets of $3.7 billion and regulatory liabilities of $1.2 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. A loss in value of an equity method investment is recognized when the decline is deemed to be other than temporary. Unforeseen events and changes in market conditions could have a material effect on the value of long-lived assets, including intangibles, goodwill and equity method investments due to changes in estimates of future cash flows, interest rate and regulatory matters and could result in an impairment charge. We recorded goodwill impairment of $0-, $252 million and $0-\) during 2013, 2012 and 2011. We did not record material impairments to long-lived assets, including intangibles, or equity method investments during 2013, 2012, and 2011.

We performed our annual goodwill impairment test in the third quarter of 2013 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 value of our Natural Gas Distribution and Energy Services reporting units exceeded the carrying value by approximately $2.3 billion and $259 million, respectively, or approximately 80% and 50%, excess fair value over the carrying values for each reporting unit, respectively. A key assumption in the income approach was the weighted average cost of capital of 5.1% and 6.0% applied in the valuation for Natural Gas Distributions and Energy Services, respectively.

Although there was not a goodwill asset impairment in our 2013 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 2013 annual test.

## 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 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 for a discussion of new accounting pronouncements that affect us.

## OTHER SIGNIFICANT MATTERS

Pension Plans. As discussed in Note 6(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 the Employee Retirement Income Security Act of 1974 (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 $83 million, $73 million and $35 million for 2013, 2012 and 2011, respectively. We made contributions of $83 million, $73 million and $65 million in 2013, 2012 and 2011 for the respective years. We expect to make contributions aggregating approximately $87 million in 2014.

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 $8 million, $9 million and $10 million in 2013, 2012 and 2011, respectively.

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.

As of December 31, 2013, the projected benefit obligation exceeded the market value of plan assets of our pension plans by $350 million. Changes in interest rates or the market values of the securities held by the plan during 2014 could materially, positively or negatively, change our funded status and affect the level of pension expense and required contributions.

Pension cost was $72 million, $82 million and $78 million for 2013, 2012 and 2011, respectively, of which $64 million, $67 million and $49 million impacted pre-tax earnings.

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, 2013, our qualified pension plan had an expected long-term rate of return on plan assets of 7.00%, which is a 1.00% decrease from the rate assumed as of December 31, 2012 due to the increase in the allocation to fixed income investments in our targeted asset allocation. The expected rate of return assumption was developed by a weighted-average return analysis of the targeted asset allocation for CenterPoint Energy’s plans and the expected real return for each asset class, based on the long-



term capital market assumptions, adjusted for investment fees and diversification effects, in addition to expected inflation. 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, 2013, the projected benefit obligation was calculated assuming a discount rate of 4.80%, which is a 0.80% increase from the 4.00% discount rate assumed in 2012. 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 2014, including the benefit restoration plan, is estimated to be $71 million, of which we expect $63 million to impact pre-tax earnings, based on an expected return on plan assets of 7.00% and a discount rate of 4.80% as of December 31, 2013. If the expected return assumption were lowered by 0.50% from 7.00% to 6.50%, 2014 pension cost would increase by approximately $9 million.

As of December 31, 2013, the pension plan projected benefit obligation, including the unfunded benefit restoration plan, exceeded plan assets by $350 million. If the discount rate were lowered by 0.50% from 4.80% to 4.30%, the assumption change would increase our projected benefit obligation and 2014 pension expense by approximately $103 million and $5 million, respectively. In addition, the assumption change would impact our Consolidated Balance Sheet by increasing the regulatory asset recorded as of December 31, 2013 by $84 million and would result in a charge to comprehensive income in 2013 of $12 million, net of tax.

Future changes in plan asset returns, assumed discount rates and various other factors related to the pension plan will impact our future pension expense and liabilities. We cannot predict with certainty what these factors will be.

## Item 7A. Quantitative and Qualitative Disclosures About Market Risk

## Impact of Changes in Interest Rates 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:

- Commodity price risk results from exposures to changes in spot prices, forward prices and price volatilities of commodities, such as natural gas, natural gas liquids and other energy commodities.

• 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.

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

## Interest Rate Risk

As of December 31, 2013, 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 $118 million and $0- at December 31, 2013 and 2012, respectively.

As of December 31, 2013 and 2012, we had outstanding fixed-rate debt (excluding indexed debt securities) aggregating $8.1 billion and $9.7 billion, respectively, in principal amount and having a fair value of $8.6 billion and $10.9 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 (please read Note 12 to our consolidated financial statements). However, the fair value of these instruments would increase by approximately $222 million if interest rates were to decline by 10% from their levels at December 31, 2013. 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 10 to our consolidated financial statements, the ZENS obligation is bifurcated into a debt component and a derivative component. The debt component of $143 million at December 31, 2013 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 $24 million if interest rates were to decline by 10% from levels at December 31, 2013. Changes in the fair value of the derivative component, a $455 million recorded liability at December 31, 2013, 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, 2013 levels, the fair value of the derivative component liability would increase by approximately $12 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, 1.8 million shares of TWC Common and 0.6 million shares of AOL Common, which we hold to facilitate our ability to meet our obligations under the ZENS. Please read Note 10 to our consolidated financial statements for a discussion of our ZENS obligation. A decrease of 10% from the December 31, 2013 aggregate market value of these shares would result in a net loss of approximately $12 million, which would be recorded as an unrealized loss in our Statements of Consolidated Income.

## Commodity Price Risk From Non-Trading Activities

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, 2013, the recorded fair value of our non-trading energy derivatives was a net asset of $13 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, 2013 levels would have decreased the fair value of our non-trading energy derivatives net asset by $4 million.

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.

# 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, 2013, based on criteria established in Internal Control—Integrated Framework (1992) 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, 2013, based on the criteria established in Internal Control—Integrated Framework (1992) 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 and financial statement schedules as of and for the year ended December 31, 2013 of the Company and our report dated February 26, 2014 expressed an unqualified opinion on those financial statements.

# 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 (1992) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on our evaluation under the framework in Internal Control — Integrated Framework (1992), our management has concluded that our internal control over financial reporting was effective as of December 31, 2013.

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, 2013 which is included herein on page 70.

# 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 facilities and natural gas distribution facilities and own interests in Enable Midstream Partners, LP (Enable) as described below. As of December 31, 2013, CenterPoint Energy’s indirect wholly owned subsidiaries included:

- CenterPoint Energy Houston Electric, LLC (CenterPoint Houston), which engages in the electric transmission and distribution business in the Texas Gulf Coast area that includes the city of Houston; and

- CenterPoint Energy Resources Corp. (CERC Corp. and, together with its subsidiaries, CERC), which owns and operates natural gas distribution systems in six states (Gas Operations). A wholly owned subsidiary of CERC Corp. offers variable and fixed-price physical natural gas supplies primarily to commercial and industrial customers and electric and gas utilities in 21 states. As of December 31, 2013, CERC Corp. also owned approximately 58.3% of the limited partner interests in Enable, an unconsolidated partnership jointly controlled with OGE Energy Corp., which owns, operates and develops natural gas and crude oil infrastructure assets.

For a description of CenterPoint Energy’s reportable business segments, see Note 17.

## (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.

On March 14, 2013, CenterPoint Energy entered into a Master Formation Agreement (MFA) with OGE Energy Corp. (OGE) and affiliates of ArcLight Capital Partners, LLC (ArcLight), pursuant to which CenterPoint Energy, OGE and ArcLight agreed to form Enable as a private limited partnership. On May 1, 2013, the parties closed on the formation of Enable. In connection with the closing (i) CERC Corp. converted its direct wholly owned subsidiary, CenterPoint Energy Field Services, LLC, a Delaware limited liability company (CEFS), into a Delaware limited partnership that became Enable, (ii) CERC Corp. contributed to Enable its equity interests in each of CenterPoint Energy Gas Transmission Company, LLC, which has been subsequently renamed Enable Gas Transmission, LLC (EGT), CenterPoint Energy - Mississippi River Transmission, LLC, which has been subsequently renamed Enable Mississippi River Transmission, LLC (MRT), certain of its other midstream subsidiaries (Other CNP Midstream Subsidiaries), and a 24.95% interest in Southeast Supply Header, LLC (SESH and, collectively with CEFS, EGT, MRT and Other CNP Midstream Subsidiaries, CenterPoint Midstream), and (iii) OGE and ArcLight indirectly contributed 100% of the equity interests in Enogex LLC, which has been subsequently renamed Enable Oklahoma Intrastate Transmission, LLC (Enogex), to Enable.

As of December 31, 2013, CERC Corp., OGE and ArcLight held approximately 58.3%, 28.5% and 13.2%, respectively, of the limited partner interests in Enable. Enable is equally controlled by CERC Corp. and OGE; each own 50% of the management rights in the general partner of Enable. CERC Corp. and OGE also own a 40% and 60% interest, respectively, in the incentive distribution rights held by the general partner of Enable. The general partner of Enable is currently governed by a board of directors made up of an equal number of representatives designated by each of CERC Corp. and OGE. See Note 9 for further discussion on the formation of Enable. The investment in Enable is accounted for utilizing the equity method of accounting. As of December 31,



2013, CenterPoint Energy determined that Enable was a variable interest entity (VIE); however, CenterPoint Energy is not the primary beneficiary and as such, this entity is not consolidated. See Notes 9 and 17 below.

Prior to July 2012, CenterPoint Energy owned a 50% interest in Waskom Gas Processing Company (Waskom), a Texas general partnership, which owns and operates a natural gas processing plant and natural gas gathering assets. On July 31, 2012, CenterPoint Energy purchased the 50% interest that it did not already own in Waskom, as well as other gathering and related assets from a third-party for approximately $273 million. The amount of the purchase price allocated to the acquisition of the 50% interest in Waskom was approximately $201 million, with the remaining purchase price allocated to the other gathering assets, based on a discounted cash flow methodology. The $273 million purchase price was allocated as follows: $253 million to property, plant and equipment; $16 million to goodwill; and the remaining balance to other assets and liabilities. The purchase of the 50% interest in Waskom was determined to be a business combination achieved in stages, and as such CenterPoint Energy recorded a pre-tax gain of approximately $136 million on July 31, 2012, which is the result of remeasuring its original 50% interest in Waskom to fair value. As a result of the purchase, CenterPoint Energy recorded goodwill of $24 million, which includes $17 million related to Waskom (including the re-measurement of its existing 50% interest) and $7 million related to the other gathering and related assets.

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

As of December 31, 2013, CenterPoint Energy had four VIEs consisting of transition and system restoration 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 transition and system restoration 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 advanced metering system 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’s rate-regulated businesses recognize removal costs as a component of depreciation expense in accordance with regulatory treatment. As of December 31, 2013 and 2012, these removal costs of $941 million and $919 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 asset retirement obligations has been reclassified from a regulatory liability to an asset retirement liability in accordance with accounting guidance for asset retirement obligations.

## (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 Allowance for Funds Used During Construction

Interest and allowance for funds used during construction (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. During 2013, 2012 and 2011, CenterPoint Energy capitalized interest and AFUDC of $11 million, $9 million and $4 million, respectively. During 2013, 2012 and 2011, CenterPoint Energy recorded AFUDC equity of $8 million, $6 million and $5 million, respectively, which is included in Other Income in its Statements of Consolidated Income.

## (h) Income Taxes

CenterPoint Energy files a consolidated federal income tax return and follows a policy of comprehensive interperiod tax allocation. 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.

## (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. Accounts receivable are net of an allowance for doubtful accounts of $28 million and $25 million at December 31, 2013 and 2012, respectively. The provision for doubtful accounts in CenterPoint Energy’s Statements of Consolidated Income for 2013, 2012 and 2011 was $21 million, $16 million and $26 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 also primarily 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 2013, 2012 and 2011, CenterPoint Energy recorded $4 million, $4 million and $11 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 and weather 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 all 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.

## (I) 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.

## (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 transition bonds and system restoration 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 $41 million and $54 million at December 31, 2013 and 2012, respectively, are included in other current assets in CenterPoint Energy's Consolidated Balance Sheets. Cash and cash equivalents included $207 million and $266 million at December 31, 2013 and 2012, respectively, that was held by CenterPoint Energy's transition and system restoration bond subsidiaries solely to support servicing the transition and system restoration bonds.

## (o) New Accounting Pronouncements

In February 2013, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update No. 2013-02, "Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income" (ASU 2013-02). The objective of ASU 2013-02 is to improve the transparency of changes in other comprehensive income and items reclassified out of Accumulated Other Comprehensive Income in financial statements. This new guidance is effective for a reporting entity's first reporting period beginning after December 15, 2012 and should be applied prospectively. CenterPoint Energy's adoption of this new guidance on January 1, 2013 did not have a material impact on its financial position, results of operations or cash flows.

In December 2011 and January 2013, the FASB issued Accounting Standards Update No. 2011-11, “Disclosures About Offsetting Assets and Liabilities” (ASU 2011-11) and No. 2013-01, “Clarifying the Scope of Disclosures About Offsetting Assets and Liabilities” (ASU 2013-01), respectively. The objective of ASU 2011-11 is to enhance disclosures about the nature of an entity’s rights of setoff and related arrangements associated with its financial instruments and derivative instruments. The objective of ASU 2013-01 is to clarify which instruments and transactions are subject to ASU 2011-11. Both ASU 2011-11 and ASU 2013-01 are effective for a reporting entity’s first reporting period beginning on or after January 1, 2013 and should be applied retrospectively. CenterPoint Energy’s adoption of this new guidance on January 1, 2013 did not have a material impact on its financial position, results of operations or cash flows.

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.



## (3) Property, Plant and Equipment

## (a) Property, Plant and Equipment

Property, plant and equipment includes the following:

(1) Following the formation of Enable on May 1, 2013, substantially all of the assets of CenterPoint Energy’s former Interstate Pipelines and Field Services business segments are owned by Enable.

## (b) Depreciation and Amortization

The following table presents depreciation and amortization expense for 2013, 2012 and 2011 (in millions).

<table><tr><td></td><td>2013</td><td>2012</td><td>2011</td></tr><tr><td>Depreciation expense</td><td>$ 531</td><td>$ 562</td><td>$ 529</td></tr><tr><td>Amortization expense</td><td>423</td><td>488</td><td>357</td></tr><tr><td>Total depreciation and amortization expense</td><td>$ 954</td><td>$ 1,050</td><td>$ 886</td></tr></table>

## (c) Asset Retirement Obligations

A reconciliation of the changes in the asset retirement obligation (ARO) liability is as follows (in millions):

<table><tr><td rowspan="2"></td><td colspan="3">December 31,</td></tr><tr><td>2013</td><td>2012</td><td></td></tr><tr><td>Beginning balance</td><td>$     164</td><td>$     156</td><td></td></tr><tr><td>Accretion expense</td><td>5</td><td>7</td><td></td></tr><tr><td>Revisions in estimates of cash flows</td><td>(35)</td><td>1</td><td></td></tr><tr><td>Ending balance</td><td>$     134</td><td>$     164</td><td></td></tr></table>

The decrease of $35 million in the ARO from the revision of estimate in 2013 is primarily attributable to a decrease in the future expected cash flows associated with the retirement of steel pipe. There were no material additions or settlements during the year ended December 31, 2012.



## (4) Goodwill

Goodwill by reportable business segment as of December 31, 2012 and changes in the carrying amount of goodwill as of December 31, 2013 are as follows (in millions):

<table><tr><td></td><td>December 31, 2011</td><td>Impairment Charge</td><td>Waskom Acquisition (1)</td><td>December 31, 2012</td><td>Contributed to Enable (1)</td><td>December 31, 2013</td></tr><tr><td>Natural Gas Distribution</td><td>$ 746</td><td>$ —</td><td>$ —</td><td>$ 746</td><td>$ —</td><td>$ 746</td></tr><tr><td>Interstate Pipelines</td><td>579</td><td>—</td><td>—</td><td>579</td><td>579</td><td>—</td></tr><tr><td>Energy Services</td><td>335</td><td>252</td><td>—</td><td>83</td><td>—</td><td>83</td></tr><tr><td>Field Services</td><td>25</td><td>—</td><td>24</td><td>49</td><td>49</td><td>—</td></tr><tr><td>Other</td><td>11</td><td>—</td><td>—</td><td>11</td><td>—</td><td>11</td></tr><tr><td>Total</td><td>$ 1,696</td><td>$ 252</td><td>$ 24</td><td>$ 1,468</td><td>$ 628</td><td>$ 840</td></tr></table>

(1) See Note 2(b).

CenterPoint Energy performs its 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 in order to determine the amount of the goodwill impairment that should be recorded. In the second step, the implied fair value of the reporting unit's goodwill is determined by allocating the reporting unit's fair value to all of its assets and liabilities other than goodwill (including any unrecognized intangible assets) in a manner similar to a purchase price allocation. The resulting implied fair value of the goodwill that results from the application of this second step is then compared to the carrying amount of the goodwill and an impairment charge is recorded for the difference.

CenterPoint Energy performed its annual impairment test in the third quarter of 2013 and determined, based on the results of the first step, that no impairment charge was required for any reportable segment. Other intangibles were not material as of December 31, 2013 and 2012.

CenterPoint Energy performed its annual impairment test in the third quarter of 2012 and determined that a non-cash goodwill impairment charge in the amount of $252 million was required for the Energy Services reportable segment.

CenterPoint Energy estimated the value of the Energy Services reporting unit using an income approach. Under this approach, the fair value of the reporting unit is determined by using the present value of future expected cash flows, which are based on management projections of revenue growth, gross margin, and overall market conditions. These estimated future cash flows are then discounted using a rate that approximates the weighted average cost of capital of a market participant.

The Energy Services reporting unit fair value analysis resulted in an implied fair value of goodwill of $83 million for this reporting unit, and as a result, a non-cash impairment charge in the amount of $252 million was recorded in the third quarter of 2012. The adverse wholesale market conditions facing CenterPoint Energy’s energy services business, specifically the prospects for continued low geographic and seasonal price differentials for natural gas, led to a reduction in the estimate of the fair value of goodwill associated with this reporting unit.



## (5) Regulatory Accounting

## (a) Regulatory Assets and Liabilities

The following is a list of regulatory assets/liabilities reflected on CenterPoint Energy’s Consolidated Balance Sheets as of December 31, 2013 and 2012:

<table><tr><td rowspan="3"></td><td colspan="3">December 31,</td></tr><tr><td>2013</td><td colspan="2">2012</td></tr><tr><td colspan="3">(in millions)</td></tr><tr><td>Securitized regulatory assets</td><td>$ 3,179</td><td>$ 3,545</td><td></td></tr><tr><td>Unrecognized equity return (1)</td><td>(508)</td><td>(553)</td><td></td></tr><tr><td>Unamortized loss on reacquired debt</td><td>111</td><td>119</td><td></td></tr><tr><td>Pension and postretirement-related regulatory asset (2)</td><td>732</td><td>1,021</td><td></td></tr><tr><td>Other long-term regulatory assets (3)</td><td>212</td><td>192</td><td></td></tr><tr><td>Total regulatory assets</td><td>3,726</td><td>4,324</td><td></td></tr><tr><td>Estimated removal costs</td><td>941</td><td>919</td><td></td></tr><tr><td>Other long-term regulatory liabilities</td><td>211</td><td>174</td><td></td></tr><tr><td>Total regulatory liabilities</td><td>1,152</td><td>1,093</td><td></td></tr><tr><td>Total regulatory assets and liabilities, net</td><td>$ 2,574</td><td>$ 3,231</td><td></td></tr></table>

(1) As of December 31, 2013, CenterPoint Energy has not recognized an allowed equity return of $508 million because such return will be recognized as it is recovered in rates. During the years ended December 31, 2013, 2012 and 2011, CenterPoint Houston recognized approximately $45 million, $47 million and $21 million, respectively, of the allowed equity return.

(2) CenterPoint Houston’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 $5 million and $14 million as of December 31, 2013 and 2012, respectively, were not earning a return.

(3) Other regulatory assets that are not earning a return were not material as of December 31, 2013 and 2012.

## (b) Resolution of True-Up Appeal

In March 2004, CenterPoint Houston filed a true-up application with the Public Utility Commission of Texas (Texas Utility Commission) requesting recovery of $3.7 billion, excluding interest, as allowed under the Texas Electric Choice Plan. The legislation provided for a transition period to move to a 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. In December 2004, the Texas Utility Commission issued a final order (True-Up Order) allowing CenterPoint Houston to recover a true-up balance of approximately $2.3 billion. To reflect the impact of the True-Up Order, in 2004 and 2005, CenterPoint Energy recorded a net after-tax extraordinary loss of $947 million.

Various parties, including CenterPoint Houston, appealed the True-Up Order. In March 2011, the Texas Supreme Court issued a unanimous ruling on such appeals in which it affirmed in part and reversed in part the decision of the Texas Utility Commission. The case was remanded to the Texas Utility Commission, and in October 2011, the Texas Utility Commission approved a final order (the Remand Order) which provided that (i) CenterPoint Houston was entitled to recover an additional true-up balance of $1.695 billion (the Recoverable True-Up Balance), (ii) no further interest would accrue on the Recoverable True-Up Balance, and (iii) CenterPoint Houston would reimburse certain parties for their reasonable rate case expenses.

In January 2012, CenterPoint Energy Transition Bond Company IV, LLC (Bond Company IV), a new special purpose subsidiary of CenterPoint Houston, issued $1.695 billion of transition bonds to securitize the Recoverable True-Up Balance.

As a result of the Remand Order, in 2011 CenterPoint Houston recorded a pre-tax extraordinary gain of $921 million ($587 million after taxes of $334 million) and $352 million ($224 million after-tax) of Other Income related to a portion of interest on the appealed amount. An additional $405 million ($258 million after-tax) will be recorded as an equity return over the life of the transition bonds.



## (6) Stock-Based Incentive Compensation Plans and Employee Benefit Plans

## (a) Stock-Based Incentive Compensation Plans

CenterPoint Energy has long-term incentive plans (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 2013, 2012 and 2011 are distributed based upon the achievement of certain objectives over a three-year performance cycle. The stock awards granted in 2013, 2012 and 2011 are subject to the performance condition that total common dividends declared during the three-year vesting period must be at least $2.49, $2.43 and $2.37 per share, respectively. 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 in order to satisfy stock-based payments related to LTIPs.

CenterPoint Energy recorded LTIP compensation expense of $19 million, $18 million and $19 million for the years ended December 31, 2013, 2012 and 2011, 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, $7 million and $7 million for the years ended December 31, 2013, 2012 and 2011, respectively. No compensation cost related to LTIPs was capitalized as a part of inventory or fixed assets in 2013, 2012 or 2011. The actual tax benefit realized for tax deductions related to LTIPs totaled $13 million, $14 million and $8 million for 2013, 2012 and 2011, respectively.

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.

The following tables summarize CenterPoint Energy’s LTIP activity for 2013:

As of December 31, 2013, there was $18 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 1.6 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. Under plan amendments, effective in early 1999, healthcare benefits for future retirees were changed to limit employer contributions for medical coverage.

Such benefit costs are accrued over the active service period of employees. The net unrecognized transition obligation is being amortized over approximately 20 years.

CenterPoint Energy’s net periodic cost includes the following components relating to pension, including the benefit restoration plan, and postretirement benefits:

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

Year Ended December 31,

<table><tr><td rowspan="3"></td><td colspan="3">2013</td><td colspan="3">2012</td><td colspan="2">2011</td></tr><tr><td rowspan="2">Pension Benefits</td><td rowspan="2">Post-retirement Benefits</td><td rowspan="2">Pension Benefits</td><td rowspan="2">Post-retirementBenefits</td><td rowspan="2">Pension Benefits</td><td rowspan="2">Post-retirements</td><td rowspan="2">Pension Benefits</td><td rowspan="2">Post-retirement Benefits</td></tr><tr></tr><tr><td>Discount rate</td><td>4.00%</td><td>3.90%</td><td>4.90%</td><td>4.80%</td><td>5.25%</td><td>5.20%</td><td></td><td></td></tr><tr><td>Expected return on plan assets</td><td>8.00</td><td>5.50</td><td>8.00</td><td>5.50</td><td>8.00</td><td>7.05</td><td></td><td></td></tr><tr><td>Rate of increase in compensation levels</td><td>4.00</td><td>—</td><td>4.20</td><td>—</td><td>4.60</td><td>—</td><td></td><td></td></tr></table>

In determining net periodic benefits cost, CenterPoint Energy uses fair value, as of the beginning of the year, as its basis for determining expected return on plan assets.



The following table summarizes changes in the benefit obligation, plan assets, the amounts recognized in consolidated balance sheets and the key assumptions of CenterPoint Energy’s pension, including benefit restoration, and postretirement plans. The measurement dates for plan assets and obligations were December 31, 2013 and 2012.

The accumulated benefit obligation for all defined benefit pension plans was $2,123 million and $2,283 million as of December 31, 2013 and 2012, respectively.

The expected rate of return assumption was developed by a weighted-average return analysis of the targeted asset allocation of CenterPoint Energy’s plans and the expected real return for each asset class, based on the long-term capital market assumptions, adjusted for investment fees and diversification effects, in addition to expected inflation.

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 7.00% and 7.50% for the pre-65 and post-65 retirees, respectively, and the prescription cost is assumed to increase 7.00% during 2014, after which this rate decreases until reaching the ultimate trend rate of 5.50% in 2018.

CenterPoint Energy’s changes in accumulated comprehensive loss related to defined benefit, postretirement and other postemployment plans are as follows (in millions):

<table><tr><td></td><td>Year Ended December 31, 2013</td></tr><tr><td>Beginning Balance</td><td>$ (132)</td></tr><tr><td>Other comprehensive income before reclassifications (1)</td><td>52</td></tr><tr><td>Amounts reclassified from accumulated other comprehensive income:</td><td></td></tr><tr><td>Prior service cost (2)</td><td>3</td></tr><tr><td>Actuarial losses (2)</td><td>14</td></tr><tr><td>Total reclassifications from accumulated other comprehensive income</td><td>17</td></tr><tr><td>Tax expense</td><td>(25)</td></tr><tr><td>Net current period other comprehensive income</td><td>44</td></tr><tr><td>Ending Balance</td><td>$ (88)</td></tr></table>

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.

As part of the investment strategy discussed above, CenterPoint Energy has adopted and maintains the following weighted average allocation targets for its benefit plans:

<table><tr><td></td><td>Pension Benefits</td><td>Postretirement Benefits</td></tr><tr><td>U.S. equity</td><td>15 - 31%</td><td>14 - 24%</td></tr><tr><td>International developed market equity</td><td>8 - 18%</td><td>3 - 13%</td></tr><tr><td>Emerging market equity</td><td>4 - 14%</td><td>—</td></tr><tr><td>Fixed income</td><td>49 - 61%</td><td>68 - 78%</td></tr><tr><td>Cash</td><td>0 - 2%</td><td>0 - 2%</td></tr></table>

## (c) Savings Plan

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 (ESOP) 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. The Company 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 or a portion of their contributions to the plan in CenterPoint Energy common stock, to have dividends reinvested in additional shares or to receive dividend payments in cash on any investment in CenterPoint Energy common stock, and to transfer all or part of their investment in CenterPoint Energy common stock to other investment options offered by the plan.

The savings plan has significant holdings of CenterPoint Energy common stock. As of December 31, 2013, 18,029,972 shares of CenterPoint Energy’s common stock were held by the savings plan, which represented approximately 21% of its investments. Given the concentration of the investments in CenterPoint Energy’s 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, $36 million and $35 million in 2013, 2012 and 2011, respectively.

## (d) Postemployment Benefits

CenterPoint Energy provides postemployment benefits for 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). The Company recorded postemployment expenses of $4 million, $8 million and $7 million in 2013, 2012 and 2011, respectively.



Included in “Benefit Obligations” in the accompanying Consolidated Balance Sheets at December 31, 2013 and 2012 was $30 million and $32 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, 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 $5 million for each of the years in 2013, 2012 and 2011. Included in “Benefit Obligations” in the accompanying Consolidated Balance Sheets at December 31, 2013 and 2012 was $64 million and $71 million, respectively, relating to deferred compensation plans.

Included in Benefit Obligations in CenterPoint Energy’s Consolidated Balance Sheets at December 31, 2013 and 2012 was $28 million and $29 million, respectively, relating to split-dollar life insurance arrangements.

## (f) Change in Control Agreements and Other Employee Matters

CenterPoint Energy has agreements with certain of its officers that generally provide, 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. These agreements are for a one-year term with automatic renewal unless action is taken by CenterPoint Energy’s board of directors prior to the renewal.

As of December 31, 2013, approximately 30% of CenterPoint Energy’s employees were subject to collective bargaining agreements.

## (7) 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 and weather on its operating results and cash flows.

## (a) Non-Trading Activities

Derivative Instruments. CenterPoint Energy enters into certain derivative instruments to manage physical commodity price risks and does not engage in proprietary or speculative commodity trading. 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 its gas operations in Arkansas, Louisiana, Mississippi and Oklahoma. Gas operations in Texas and Minnesota and electric operations in Texas do not have such mechanisms. As a result, fluctuations from normal weather may have a significant positive or negative effect on Gas Operations’ results in Texas and Minnesota and on CenterPoint Houston’s results in its service territory.

In 2013 and 2012, CenterPoint Energy entered into heating-degree day swaps for certain Gas Operations jurisdictions to mitigate the effect of fluctuations from normal weather on its results of operations and cash flows for the winter heating season. In 2013, CenterPoint Energy also entered into a similar winter weather hedge for the CenterPoint Houston service territory. The swaps are based on ten-year normal weather. During the years ended December 31, 2013, 2012 and 2011, CenterPoint Energy recognized losses of $22 million, gains of $8 million and losses of less than $1 million, respectively, related to these swaps. Weather hedge gains and losses are included in revenues in the Statements of Consolidated Income.



## (b) Derivative Fair Values and Income Statement Impacts

The following tables present information about CenterPoint Energy’s derivative instruments and hedging activities. The first two tables provide a balance sheet overview of CenterPoint Energy’s Derivative Assets and Liabilities as of December 31, 2013 and 2012, while the last table provides a breakdown of the related income statement impacts for the years ending December 31, 2013 and 2012.

(1) The fair value shown for natural gas contracts is comprised of derivative gross volumes totaling 607 Bcf or a net 46 Bcf long position. Of the net long position, basis swaps constitute 99 Bcf.

(2) The $28 million Derivative Current Asset includes $1 million related to physical forwards purchased from Enable.

(3) Natural gas contracts are presented on a net basis in the Consolidated Balance Sheets. Natural gas contracts are subject to master netting arrangements. This netting applies to all undisputed amounts due or past due and causes derivative assets (liabilities) to be ultimately presented net in a liability (asset) account within the Consolidated Balance Sheets. The net of total non-trading derivative assets and liabilities was a $13 million asset as shown on CenterPoint Energy’s Consolidated Balance Sheets (and as detailed in the table below), and was comprised of the natural gas contracts derivative assets and liabilities separately shown above offset by collateral netting of less than $1 million.

(2) Natural gas contracts are presented on a net basis in the Consolidated Balance Sheets. Natural gas contracts are subject to master netting arrangements. This netting applies to all undisputed amounts due or past due and causes derivative assets (liabilities) to be ultimately presented net in a liability (asset) account within the Consolidated Balance Sheets. The net of total non-trading derivative assets and liabilities was a $26 million asset as shown on CenterPoint Energy’s Consolidated Balance Sheets (and as detailed in the table below), and was comprised of the natural gas contracts derivative assets and liabilities separately shown above offset by collateral netting of $9 million.

(1) Gross amounts recognized include some derivative assets and liabilities that are not subject to master netting arrangements.

(2) The derivative assets and liabilities on the Consolidated Balance Sheets exclude accounts receivable or accounts payable that, should they exist, could be used as offsets to these balances in the event of a default.

For CenterPoint Energy’s price stabilization activities of the Natural Gas Distribution business segment, the settled costs of derivatives are ultimately recovered through purchased gas adjustments. Accordingly, the net unrealized gains and losses associated with these contracts are recorded as net regulatory assets. Realized and unrealized gains and losses on other derivatives are recognized in the Statements of Consolidated Income as revenue for retail sales derivative contracts and as natural gas expense for financial natural gas derivatives and non-retail related physical natural gas derivatives. Unrealized gains and losses on indexed debt securities are recorded as Other Income (Expense) in the Statements of Consolidated Income.



<table><tr><td rowspan="2">Total derivatives not designated as hedging instruments</td><td rowspan="2">Income Statement Location</td><td colspan="4">Year Ended December 31,</td></tr><tr><td>2013</td><td colspan="2">2012</td><td>2011</td></tr><tr><td></td><td></td><td colspan="4">(in millions)</td></tr><tr><td>Natural gas derivatives</td><td>Gains (Losses) in Revenue</td><td>$ 11</td><td>$ 43</td><td>$ 102</td><td></td></tr><tr><td>Natural gas derivatives (1) (2)</td><td>Gains (Losses) in Expense: Natural Gas</td><td>10</td><td>(63)</td><td>(144)</td><td></td></tr><tr><td>Indexed debt securities derivative</td><td>Gains (Losses) in Other Income (Expense)</td><td>(193)</td><td>(71)</td><td>35</td><td></td></tr><tr><td>Total</td><td></td><td>$ (172)</td><td>$ (91)</td><td>$ (7)</td><td></td></tr></table>

(1) The Gains (Losses) in Expense: Natural Gas includes $(2) million during the year ended December 31, 2013 related to physical forwards purchased from Enable.

(2) The Gains (Losses) in Expense: Natural Gas includes $0-, $(38) million and (107) million of costs in 2013, 2012 and 2011, respectively, associated with price stabilization activities of the Natural Gas Distribution business segment that will be ultimately recovered through purchased gas adjustments.

## (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 Standard & Poor’s Ratings Services or Moody’s Investors Service, Inc. 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 at December 31, 2013 and 2012 was $1 million and $5 million, respectively. The aggregate fair value of assets that are already posted as collateral was less than $1 million at both December 31, 2013 and 2012. If all derivative contracts (in a net liability position) containing credit risk contingent features were triggered at December 31, 2013 and 2012, $1 million and $5 million, respectively, of additional assets would be required to be posted as collateral.

## (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, 2013 and 2012 (in millions):

<table><tr><td rowspan="2"></td><td colspan="3">December 31, 2013</td><td colspan="3">December 31, 2012</td></tr><tr><td>Investment Grade(1)</td><td colspan="2">Total</td><td>Investment Grade(1)</td><td colspan="2">Total</td></tr><tr><td>Energy marketers</td><td>$ 1</td><td>$ 4</td><td>$ 1</td><td>$ 1</td><td>$ 1</td><td></td></tr><tr><td>Financial institutions</td><td>1</td><td>9</td><td>—</td><td>—</td><td>—</td><td></td></tr><tr><td>Retail end users (2)</td><td>1</td><td>21</td><td>—</td><td>—</td><td>41</td><td></td></tr><tr><td>Total</td><td>$ 3</td><td>$ 34</td><td>$ 1</td><td>$ 42</td><td></td><td></td></tr></table>

(1) “Investment grade” is primarily determined using publicly available credit ratings and considering 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 considering contractual rights and restrictions and collateral.

(2) Retail end users represent customers who have contracted to fix the price of a portion of their physical gas requirements for future periods.



## (8) 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, 2013, CenterPoint Energy’s Level 3 assets and liabilities are comprised of physical forward contracts and options. Level 3 physical forward contracts are valued using a discounted cash flow model which includes illiquid forward price curve locations (ranging from $3.79 to $4.94 per one million British thermal units (Btu)) 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 53%) as an unobservable input. CenterPoint Energy’s Level 3 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 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, 2013, 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 as of December 31, 2013 and 2012, and indicate the fair value hierarchy of the valuation techniques utilized by CenterPoint Energy to determine such fair value.

(1) During 2013, 2012 and 2011, CenterPoint Energy did not have Level 3 unrealized gains (losses) or settlements related to price stabilization activities of the Natural Gas Distribution business segment.

(2) During 2013, 2012 and 2011, CenterPoint Energy did not have significant Level 3 sales.



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 fair values of non-trading derivative assets and liabilities and CenterPoint Energy’s 2.0% Zero-Premium Exchangeable Subordinated Notes due 2029 (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 using market interest rates on the applicable dates. 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 in the fair value hierarchy.

## (9) Unconsolidated Affiliates

As discussed in Note 2, on May 1, 2013 (the Closing Date) CERC Corp., OGE and ArcLight closed on the formation of Enable. Enable owns CenterPoint Midstream, which consists of substantially all of CERC Corp.'s former Interstate Pipelines and Field Services business segments. As a result, CenterPoint Energy no longer has Interstate Pipelines or Field Services business segments. Equity earnings associated with CenterPoint Energy's interest in Enable and equity earnings associated with its retained 25.05% interest in SESH are now reported under the Midstream Investments segment. For a further description of CenterPoint Energy's reportable business segments, see Note 17.

The formation of Enable by CenterPoint Energy has been considered a contribution of in-substance real estate to a limited partnership as the businesses are composed of, and reliant upon, substantial real estate assets and integral equipment. Real estate assets and integral equipment primarily includes gas transmission pipelines, compressor station equipment, rights of way, storage and processing assets and long-term customer contracts. Accordingly, CenterPoint Energy did not recognize a gain or loss upon contribution and recorded its investment in Enable using the equity method of accounting based on the historical cost of the contributed assets and liabilities as of the Closing Date. Approximately $5.8 billion of assets (which includes $4.7 billion in property, plant and equipment, net, $629 million in goodwill and $197 million for the 24.95% investment in SESH) and $1.5 billion of liabilities (which includes the Term Loan and the indebtedness owed to CERC, both discussed below, of $1.05 billion and $363 million, respectively) were contributed by CERC Corp. CenterPoint Energy has the ability to significantly influence the operating and financial policies of Enable and, accordingly, recorded an equity method investment, at the historical costs of net assets contributed, of $4.3 billion in Enable on the Closing Date. Pursuant to the MFA, CenterPoint Energy retained certain assets and liabilities historically held by CenterPoint Midstream such as balances relating to federal income taxes and benefit plan obligations.

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. Under the equity method, CenterPoint Energy’s investment will be adjusted each period for contributions made, distributions received, CenterPoint Energy’s share of Enable’s comprehensive income and accretion of any basis difference. CenterPoint Energy’s maximum exposure to loss related to Enable is limited to its equity investment as presented in the Consolidated Balance Sheet at December 31, 2013 and its guarantee of Enable’s $1.05 billion Term Loan and certain other guarantees as discussed in Note 14. 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. See Note 1 for further discussion on Enable’s ownership structure.

Effective on the Closing Date, CenterPoint Energy and Enable entered into a Services Agreement, Employee Transition Agreement, Transitional Services Agreement and other agreements (collectively, Transition Agreements) whereby CenterPoint Energy agreed to provide certain support services to Enable such as accounting, legal, risk management and treasury functions for an initial term ending on April 30, 2016. The support services automatically extend year-to-year at the end of the initial term, unless terminated by Enable with at least 90 days' notice. Enable may terminate these support services at any time with 180 days'



notice if approved by the board of Enable’s general partner. Additionally, CenterPoint Energy agreed to provide seconded employees to Enable to support its operations for an initial term ending on December 31, 2014, unless revised by mutual agreement with CenterPoint Energy, OGE and Enable prior to that date. CenterPoint Energy did not transfer any employees to Enable at formation of the partnership or at any time during the year ended December 31, 2013. CenterPoint Energy billed Enable for reimbursement of transitional services, including the costs of seconded employees, of $119 million during the year ended December 31, 2013 under the Transition Agreements. Actual transitional services costs are recorded net of reimbursements received from Enable. CenterPoint Energy had accounts receivable from Enable of $24 million at December 31, 2013 for amounts billed for transitional services, including the cost of seconded employees.

Enable, at its discretion, has the right to select and offer employment to seconded employees from CenterPoint Energy. As of December 31, 2013, CenterPoint Energy determined it cannot reasonably estimate the impact of the costs associated with the termination of employees related to the formation of Enable or transfer of employees from CenterPoint Energy to Enable, including the impact of the changes to the actuarial determination of employee benefit plan obligations. Pursuant to the Transition Agreements, Enable has agreed to reimburse CenterPoint Energy for severance and termination costs related to the termination of CenterPoint Energy’s seconded employees, including any potential benefit-related costs, regardless of whether such seconded employees are offered employment by Enable.

On the Closing Date, Enable entered into a $1.05 billion three-year senior unsecured term loan facility (the Term Loan) with third parties and repaid $1.05 billion of affiliated notes payable (Affiliated Notes Payable) owed to CERC. CERC provided a guarantee of collection of Enable’s obligations under the Term Loan. The guarantee is subordinated to all senior debt of CERC. Certain of the entities contributed to Enable by CERC are obligated on approximately $363 million of indebtedness owed to CERC bearing interest at an annual rate of 2.10% to 2.45% and scheduled to mature in 2017. CenterPoint Energy recognized interest income of $5 million for the period May 1, 2013 to December 31, 2013 on its notes receivable of $363 million due from Enable.

CERC has certain put rights, and Enable has certain call rights, exercisable with respect to the 25.05% interest in SESH retained by CERC, under which CERC would contribute its retained interest in SESH, in exchange for a specified number of limited partnership units in Enable and a cash payment, payable either from CERC to Enable or from Enable to CERC, for changes in the value of SESH. CERC can exercise its first put right in May 2014 pursuant to which CERC would contribute an additional 24.95% interest in SESH to Enable.

For the period May 1, 2013 to December 31, 2013, CenterPoint Energy incurred natural gas expenses, including transportation and storage costs, of $123 million for transactions with Enable. CenterPoint Energy had accounts payable to Enable of $22 million at December 31, 2013 from such transactions.

As of December 31, 2013, CenterPoint Energy held an approximate 58.3% limited partner interest in Enable and a 25.05% interest in SESH.

(1) This difference related to CenterPoint Energy’s proportionate share of Enable’s goodwill arising from its acquisition of Enogex, and therefore will not be recognized by CenterPoint Energy.

Enable concluded that the formation of Enable is considered a business combination, and CenterPoint Midstream is the acquirer for accounting purposes. Under this method, the fair value of the consideration paid by CenterPoint Midstream for Enogex is allocated to the assets acquired and liabilities assumed on the Closing Date based on their fair value. Enogex’s assets, liabilities and equity were accordingly adjusted to estimated fair value as of May 1, 2013. Determining the fair value of assets and liabilities is judgmental in nature and often involves the use of significant estimates and assumptions. Enable used appraisers to assist in the determination of the estimated fair value of certain assets and liabilities contributed by Enogex.

Cash distributions received from Enable and SESH were approximately $106 million and $23 million, respectively, during the year ended December 31, 2013.

## (10) Indexed Debt Securities (ZENS) and Time Warner Securities

## (a) Investment in Time Warner Securities

In 1995, CenterPoint Energy sold a cable television subsidiary to Time Warner, Inc. (TW) and received TW securities as partial consideration. A subsidiary of CenterPoint Energy now holds 7.1 million shares of TW common stock (TW Common), 1.8 million shares of Time Warner Cable Inc. (TWC) common stock (TWC Common) and 0.6 million shares of AOL, Inc. (AOL) common stock (AOL Common) (together with the TW Common and TWC Common, the TW Securities) 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.

## (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, 2013. Each ZENS note 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 note are adjusted for certain corporate events. As of December 31, 2013, the reference shares for each ZENS note consisted of 0.5 share of TW Common, 0.125505 share of TWC Common and 0.045455 share of AOL Common. On February 13, 2014, TWC announced that it had agreed to merge with Comcast Corporation (Comcast). In the merger, each share of TWC Common would be exchanged for 2.875 shares of Comcast common stock (Comcast Common). Upon the closing of the merger (assuming no change in the merger consideration), the reference shares for each ZENS note would include 0.360827 share of Comcast Common in place of the current 0.125505 share of TWC Common. 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, 2013, ZENS having an original principal amount of $828 million and a contingent principal amount of $763 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. At December 31, 2013, the market value of such shares was approximately $767 million, which would provide an exchange amount of $880 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 17.3% 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.

The following table sets forth summarized financial information regarding CenterPoint Energy’s investment in TW Securities and each component of CenterPoint Energy’s ZENS obligation (in millions).

## (a) Short-term Borrowings

Inventory Financing. Gas Operations has asset management agreements associated with its utility distribution service in Arkansas, north Louisiana and Oklahoma that extend through 2015. Pursuant to the provisions of the agreements, Gas Operations 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 a financing and they had an associated principal obligation of $43 million and $38 million as of December 31, 2013 and 2012, respectively.

## (b) Long-term Debt

Debt Repayments. In March 2013, CenterPoint Energy Houston Electric, LLC (CenterPoint Houston) retired $450 million aggregate principal amount of its 5.70% general mortgage bonds at their maturity.

In April 2013, CERC Corp. retired approximately $365 million aggregate principal amount of its 7.875% senior notes at their maturity. The retirement of senior notes was financed by CERC Corp. with the issuance of commercial paper. In May 2013, CERC Corp. applied proceeds from Enable's May 1, 2013 debt repayment of $1.05 billion to the repayment of $357 million aggregate principal amount of its commercial paper and to the May 31, 2013 redemption of $160 million aggregate principal amount of its 5.95% senior notes due January 15, 2014 at 103.419% of their aggregate principal amount.

On August 1, 2013, approximately $92 million aggregate principal amount of pollution control bonds issued on CenterPoint Energy’s behalf were redeemed at 101% of their aggregate principal amount. These bonds had an interest rate of 4%, a maturity date of August 1, 2015 and were collateralized by first mortgage bonds of CenterPoint Houston.

On October 15, 2013, approximately $59 million aggregate principal amount of pollution control bonds issued on CenterPoint Energy’s behalf were redeemed at 101% of their aggregate principal amount. These bonds had an interest rate of 4%, a maturity date of October 15, 2015 and were collateralized by first mortgage bonds of CenterPoint Houston.

In January 2014, approximately $44 million aggregate principal amount of pollution control bonds issued on behalf of CenterPoint Houston were called for redemption on March 3, 2014 at 101% of their principal amount plus accrued interest. The bonds have an interest rate of 4.25%, mature in 2017 and are collateralized by general mortgage bonds of CenterPoint Houston.

In February 2014, notice was given that approximately $56 million aggregate principal amount of pollution control bonds issued on behalf of CenterPoint Houston must be tendered for purchase by CenterPoint Houston on March 3, 2014 at 101% of their principal amount plus accrued interest pursuant to the mandatory tender provisions of the bonds. The bonds have an interest rate of 5.60%, mature in 2027 and are collateralized by general mortgage bonds of CenterPoint Houston. The purchased pollution control bonds may be remarketed.

Transition and System Restoration Bonds. As of December 31, 2013, CenterPoint Houston had four special purpose subsidiaries consisting of transition and system restoration 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 transition bonds and system restoration 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 payable by most of CenterPoint Houston’s retail electric customers in order to provide recovery of authorized qualified costs. CenterPoint Houston has no payment obligations in respect of the transition and system restoration 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 CenterPoint Houston have no recourse to any assets or revenues of the transition and system restoration bond companies (including the transition and system restoration charges), and the holders of transition bonds or system restoration bonds have no recourse to the assets or revenues of CenterPoint Energy or CenterPoint Houston.



Credit Facilities. As of December 31, 2013 and 2012, CenterPoint Energy, CenterPoint Houston and CERC Corp. had the following revolving credit facilities and utilization of such facilities (in millions):

<table><tr><td rowspan="2"></td><td colspan="6">December 31, 2013</td><td colspan="6">December 31, 2012</td></tr><tr><td>Size of Facility</td><td>Loans</td><td>Letters of Credit</td><td>Commercial Paper</td><td>Size of Facility</td><td>Loans</td><td>Letters of Credit</td><td>Commercial Paper</td><td></td><td></td><td></td><td></td></tr><tr><td>CenterPoint Energy.....</td><td>$ 1,200</td><td>$ —</td><td>$ 6</td><td>$ —</td><td>$ 1,200</td><td>$ —</td><td>$ 7</td><td>$ —</td><td></td><td></td><td></td><td></td></tr><tr><td>CenterPoint Houston...</td><td>300</td><td>—</td><td>4</td><td>—</td><td>300</td><td>—</td><td>4</td><td>—</td><td></td><td></td><td></td><td></td></tr><tr><td>CERC Corp.</td><td>600</td><td>—</td><td>—</td><td>118</td><td>950</td><td>—</td><td>—</td><td>—</td><td></td><td></td><td></td><td></td></tr><tr><td>Total</td><td>$ 2,100</td><td>$ —</td><td>$ 10</td><td>$ 118</td><td>$ 2,450</td><td>$ —</td><td>$ 11</td><td>$ —</td><td></td><td></td><td></td><td></td></tr></table>

CenterPoint Energy’s $1.2 billion revolving credit facility, which is scheduled to terminate on September 9, 2018, can be drawn at the London Interbank Offered Rate (LIBOR) plus 125 basis points based on CenterPoint Energy’s current credit ratings. The revolving credit facility contains a financial covenant which limits CenterPoint Energy’s consolidated debt (excluding transition and system restoration bonds) to an amount not to exceed 65% of CenterPoint Energy’s consolidated capitalization. The financial covenant limit will temporarily increase from 65% to 70% if CenterPoint Houston experiences damage from a natural disaster in its service territory and CenterPoint Energy certifies to the administrative agent that CenterPoint Houston has incurred system restoration costs reasonably likely to exceed $100 million in a consecutive twelve-month period, all or part of which CenterPoint Houston 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 Houston’s $300 million revolving credit facility, which is scheduled to terminate on September 9, 2018, can be drawn at LIBOR plus 112.5 basis points based on CenterPoint Houston’s current credit ratings. The revolving credit facility contains a financial covenant which limits CenterPoint Houston’s consolidated debt (excluding transition and system restoration bonds) to an amount not to exceed 65% of CenterPoint Houston’s consolidated capitalization.

CERC Corp.’s $600 million revolving credit facility, which is scheduled to terminate on September 9, 2018, can be drawn at LIBOR plus 150 basis points based on CERC Corp.’s current credit ratings. The revolving credit facility contains a financial covenant which limits CERC’s consolidated debt to an amount not to exceed 65% of CERC’s consolidated capitalization.

CenterPoint Energy, CenterPoint Houston and CERC Corp. were in compliance with all financial debt covenants as of December 31, 2013.

Maturities. CenterPoint Energy’s maturities of long-term debt, capital leases and sinking fund requirements, excluding the ZENS obligation, are $354 million in 2014, $640 million in 2015, $716 million in 2016, $1.0 billion in 2017 and $1.2 billion in 2018. These maturities include transition and system restoration bond principal repayments on scheduled payment dates aggregating $354 million in 2014, $372 million in 2015, $391 million in 2016, $411 million in 2017 and $434 million in 2018.

Liens. As of December 31, 2013, CenterPoint Houston’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 2013, 2012 and 2011 have been satisfied by certification of property additions. The replacement fund requirement to be satisfied in 2014 is approximately $198 million, and the sinking fund requirement to be satisfied in 2014 is approximately $1.6 million. CenterPoint Energy expects CenterPoint Houston to meet these 2014 obligations by certification of property additions. As of December 31, 2013, CenterPoint Houston’s assets were also subject to liens securing approximately $1.9 billion of general mortgage bonds which are junior to the liens of the first mortgage bonds.



## (13) Income Taxes

The components of CenterPoint Energy’s income tax expense were as follows:

<table><tr><td rowspan="3"></td><td colspan="4">Year Ended December 31,</td></tr><tr><td>2013</td><td colspan="2">2012</td><td>2011</td></tr><tr><td colspan="4">(in millions)</td></tr><tr><td>Current income tax expense (benefit):</td><td></td><td></td><td></td><td></td></tr><tr><td>Federal</td><td>$ 91</td><td>$ —</td><td>$ (63)</td><td></td></tr><tr><td>State</td><td>23</td><td>12</td><td>24</td><td></td></tr><tr><td>Total current expense (benefit)</td><td>114</td><td>12</td><td>(39)</td><td></td></tr><tr><td>Deferred income tax expense (benefit):</td><td></td><td></td><td></td><td></td></tr><tr><td>Federal</td><td>370</td><td>280</td><td>432</td><td></td></tr><tr><td>State</td><td>(14)</td><td>48</td><td>11</td><td></td></tr><tr><td>Total deferred expense</td><td>356</td><td>328</td><td>443</td><td></td></tr><tr><td>Total income tax expense</td><td>$ 470</td><td>$ 340</td><td>$ 404</td><td></td></tr></table>

A reconciliation of the expected federal income tax expense using the federal statutory income tax rate to the actual income tax expense and resulting effective income tax rate is as follows:

<table><tr><td rowspan="3"></td><td colspan="4">Year Ended December 31,</td></tr><tr><td>2013</td><td colspan="2">2012</td><td>2011</td></tr><tr><td colspan="4">(in millions)</td></tr><tr><td>Income before income taxes and extraordinary item</td><td>$ 781</td><td>$ 757</td><td>$ 1,174</td><td></td></tr><tr><td>Federal statutory income tax rate</td><td>35.0%</td><td>35.0%</td><td>35.0%</td><td></td></tr><tr><td>Expected federal income tax expense</td><td>273</td><td>265</td><td>411</td><td></td></tr><tr><td>Increase (decrease) in tax expense resulting from:</td><td></td><td></td><td></td><td></td></tr><tr><td>State income tax expense, net of federal income tax</td><td>21</td><td>39</td><td>22</td><td></td></tr><tr><td>Amortization of investment tax credit</td><td>—</td><td>(2)</td><td>(6)</td><td></td></tr><tr><td>Tax effect related to the formation of Enable</td><td>196</td><td>—</td><td>—</td><td></td></tr><tr><td>Increase (decrease) in settled and uncertain income tax positions</td><td>(9)</td><td>(33)</td><td>(5)</td><td></td></tr><tr><td>Goodwill impairment</td><td>—</td><td>88</td><td>—</td><td></td></tr><tr><td>Other, net</td><td>(11)</td><td>(17)</td><td>(18)</td><td></td></tr><tr><td>Total</td><td>197</td><td>75</td><td>(7)</td><td></td></tr><tr><td>Total income tax expense</td><td>$ 470</td><td>$ 340</td><td>$ 404</td><td></td></tr><tr><td>Effective tax rate</td><td>60.2%</td><td>44.9%</td><td>34.4%</td><td></td></tr></table>

CenterPoint Energy recorded a deferred tax expense of $225 million at formation of Enable related to the book-to-tax basis difference for contributed non-tax deductible goodwill and recognized a tax benefit of $29 million associated with the remeasurement of state deferred taxes at formation. In addition, CenterPoint Energy recognized a tax benefit of $8 million based on the settlement with the Internal Revenue Service (IRS) of outstanding tax claims for the 2002 and 2003 audit cycles.

CenterPoint Energy recorded a non-tax deductible impairment of goodwill of $252 million in September 2012. CenterPoint Energy recorded a net decrease in income tax expense of $28 million in 2012 related to the release of certain income tax reserves due to its settlements with the IRS.

CenterPoint Energy recorded a $9 million decrease in tax expense in 2011 related to the release of income tax reserves on the tax normalization issue discussed below, which resulted in a net decrease in tax expense of $5 million for all uncertain tax positions. CenterPoint Energy recorded a net reduction in state income tax expense of approximately $17 million related to lower blended state tax rates and a reduction of the deferred tax liability recorded in December 2011.



In September 2013, the U.S. Treasury issued final regulations addressing the tax consequences associated with the acquisition, production and improvement of tangible property. CenterPoint Energy does not expect the adoption of the regulations to have a material impact on its financial position, results of operations or cash flows.

The tax effects of temporary differences that give rise to significant portions of deferred tax assets and liabilities were as follows:

<table><tr><td rowspan="3"></td><td colspan="3">December 31,</td></tr><tr><td>2013</td><td colspan="2">2012</td></tr><tr><td colspan="3">(in millions)</td></tr><tr><td>Deferred tax assets:</td><td></td><td></td><td></td></tr><tr><td>Current:</td><td></td><td></td><td></td></tr><tr><td>Allowance for doubtful accounts</td><td>$ 11</td><td>$ 10</td><td></td></tr><tr><td>Deferred gas costs</td><td>7</td><td>—</td><td></td></tr><tr><td>Other</td><td>12</td><td>1</td><td></td></tr><tr><td>Total current deferred tax assets</td><td>30</td><td>11</td><td></td></tr><tr><td>Non-current:</td><td></td><td></td><td></td></tr><tr><td>Loss and credit carryforwards</td><td>51</td><td>90</td><td></td></tr><tr><td>Employee benefits</td><td>258</td><td>383</td><td></td></tr><tr><td>Other</td><td>76</td><td>64</td><td></td></tr><tr><td>Total non-current deferred tax assets before valuation allowance</td><td>385</td><td>537</td><td></td></tr><tr><td>Valuation allowance</td><td>(2)</td><td>(2)</td><td></td></tr><tr><td>Total non-current deferred tax assets, net of valuation allowance</td><td>383</td><td>535</td><td></td></tr><tr><td>Total deferred tax assets, net of valuation allowance</td><td>413</td><td>546</td><td></td></tr><tr><td>Deferred tax liabilities:</td><td></td><td></td><td></td></tr><tr><td>Current:</td><td></td><td></td><td></td></tr><tr><td>Unrealized gain on indexed debt securities</td><td>541</td><td>439</td><td></td></tr><tr><td>Unrealized gain on TW securities</td><td>97</td><td>151</td><td></td></tr><tr><td>Deferred gas costs</td><td>—</td><td>25</td><td></td></tr><tr><td>Total current deferred tax liabilities</td><td>638</td><td>615</td><td></td></tr><tr><td>Non-current:</td><td></td><td></td><td></td></tr><tr><td>Depreciation</td><td>1,908</td><td>3,279</td><td></td></tr><tr><td>Regulatory assets, net</td><td>1,308</td><td>1,278</td><td></td></tr><tr><td>Investment in unconsolidated affiliates</td><td>1,590</td><td>—</td><td></td></tr><tr><td>Other</td><td>119</td><td>131</td><td></td></tr><tr><td>Total non-current deferred tax liabilities</td><td>4,925</td><td>4,688</td><td></td></tr><tr><td>Total deferred tax liabilities</td><td>5,563</td><td>5,303</td><td></td></tr><tr><td>Accumulated deferred income taxes, net</td><td>$ 5,150</td><td>$ 4,757</td><td></td></tr></table>

Tax Attribute Carryforwards and Valuation Allowance. At December 31, 2013, CenterPoint Energy has approximately $387 million of state net operating loss carryforwards which expire in various years between 2015 and 2033. In addition, CenterPoint Energy has carryforward of approximately $2 million of Oklahoma State Investment Tax Credits which do not expire.

CenterPoint Energy has approximately $244 million of state capital loss carryforwards which expire in 2017 for which management established a full valuation allowance of $3 million state tax effect ($2 million net of federal tax). The valuation allowance was established based upon management’s evaluation that loss carryforwards may not be fully realized.



Uncertain Income Tax Positions. The following table reconciles the beginning and ending balance of CenterPoint Energy’s unrecognized tax benefits (expenses):

<table><tr><td rowspan="3"></td><td colspan="4">December 31,</td></tr><tr><td>2013</td><td colspan="2">2012</td><td>2011</td></tr><tr><td colspan="4">(in millions)</td></tr><tr><td>Balance, beginning of year</td><td>$ (23)</td><td>$ 51</td><td>$ 252</td><td></td></tr><tr><td>Tax Positions related to prior years:</td><td></td><td></td><td></td><td></td></tr><tr><td>Additions</td><td>—</td><td>—</td><td>(1)</td><td></td></tr><tr><td>Reductions</td><td>(1)</td><td>(75)</td><td>(203)</td><td></td></tr><tr><td>Tax Positions related to current year:</td><td></td><td></td><td></td><td></td></tr><tr><td>Additions</td><td>—</td><td>—</td><td>5</td><td></td></tr><tr><td>Settlements</td><td>24</td><td>1</td><td>(1)</td><td></td></tr><tr><td>Lapse of statute of limitations</td><td>—</td><td>—</td><td>(1)</td><td></td></tr><tr><td>Balance, end of year</td><td>$ —</td><td>$ (23)</td><td>$ 51</td><td></td></tr></table>

The net decrease in the total amount of unrecognized tax benefits during 2013 is primarily related to CenterPoint Energy’s IRS settlements related to open claims for tax years 2002 and 2003. During 2013, the IRS completed the examination cycle and settlement of tax years 2010 and 2011. CenterPoint Energy does not expect the change to the amount of unrecognized tax benefits over the twelve months ending December 31, 2014 to have a material impact on financial position, results of operations and cash flows.

CenterPoint Energy has approximately $0-, $(3) million and $21 million of unrecognized tax benefits (expenses) that, if recognized, would affect the effective income tax rate for 2013, 2012 and 2011, respectively. CenterPoint Energy recognizes interest and penalties as a component of income tax expense. CenterPoint Energy recognized approximately $3 million of income tax benefit, $7 million of income tax benefit and $13 million of income tax expense related to interest on uncertain income tax positions during 2013, 2012 and 2011, respectively. CenterPoint Energy had approximately $5 million and $8 million of interest receivable on uncertain income tax positions accrued at December 31, 2013 and 2012, respectively.

Tax Audits and Settlements. CenterPoint Energy’s consolidated federal income tax returns have been audited and settled through tax year 2011. CenterPoint Energy is currently in the early stages of examination by the IRS for tax year 2012. CenterPoint Energy has considered the effects of these examinations in its accrual for settled issues and liability for uncertain income tax positions as of December 31, 2013.

## (14) 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, 2013 and 2012 as these contracts meet the exception to be classified 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, 2013, minimum payment obligations for natural gas supply commitments are approximately $408 million in 2014, $391 million in 2015, $310 million in 2016, $250 million in 2017, $244 million in 2018 and $120 million after 2018.

## (b) Asset Management Agreements

Gas Operations has asset management agreements (AMAs) associated with its utility distribution service in Arkansas, Louisiana, Mississippi, Oklahoma and Texas. Generally, these AMAs are contracts between Gas Operations and an asset manager that are intended to transfer the working capital obligation and maximize the utilization of the assets. In these AMAs, Gas Operations agreed to release transportation and storage capacity to other parties to manage gas storage, supply and delivery arrangements for Gas Operations and to use the released capacity for other purposes when it is not needed for Gas Operations. Gas Operations 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. Gas Operations has an obligation to purchase its winter storage requirements that have been released to the asset manager under these AMAs. The AMAs have varying terms, the longest of which expires in 2016.



## (c) Lease Commitments

The following table sets forth information concerning CenterPoint Energy’s obligations under non-cancelable long-term operating leases at December 31, 2013, which primarily consist of rental agreements for building space, data processing equipment, compression equipment and rights of way (in millions):

<table><tr><td>2014</td><td>$ 6</td></tr><tr><td>2015</td><td>4</td></tr><tr><td>2016</td><td>4</td></tr><tr><td>2017</td><td>2</td></tr><tr><td>2018</td><td>2</td></tr><tr><td>2019 and beyond</td><td>3</td></tr><tr><td>Total</td><td>$ 21</td></tr></table>

Total lease expense for all operating leases was $21 million, $27 million and $43 million during 2013, 2012 and 2011, respectively.

## (d) Legal, Environmental and Other Regulatory Matters

## Legal Matters

Gas Market Manipulation Cases. CenterPoint Energy, CenterPoint Houston or their predecessor, Reliant Energy, Incorporated (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, Reliant Resources, Inc. (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 Energy, Inc. (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 Energy, Inc. (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 CenterPoint Houston, for certain liabilities, including their indemnification obligations regarding the gas market manipulation litigation, nor does it affect the terms of existing guarantee arrangements for certain GenOn gas transportation contracts discussed below.

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’s former affiliate, RRI, was a participant in gas trading in the California and Western markets. These lawsuits, many of which were filed as class actions, allege violations of state and federal antitrust laws. Plaintiffs in these lawsuits are seeking a variety of forms of relief, including, among others, recovery of compensatory damages (in some cases in excess of $1 billion), a trebling of compensatory damages, full consideration damages and attorneys’ fees. CenterPoint Energy and/or Reliant Energy were named in approximately 30 of these lawsuits, which were instituted between 2003 and 2009. CenterPoint Energy and its affiliates have since been released or dismissed from all but one such case. CenterPoint Energy Services, Inc. (CES), a subsidiary of CERC Corp., is a defendant in a case now pending in federal court in Nevada alleging a conspiracy to inflate Wisconsin natural gas prices in 2000-2002. In July 2011, the court issued an order dismissing the plaintiffs’ claims against other defendants in the case, each of whom had demonstrated FERC jurisdictional sales for resale during the relevant period, based on federal preemption. The plaintiffs appealed this ruling to the United States Court of Appeals for the Ninth Circuit, which reversed the trial court’s dismissal of the plaintiffs’ claims. In August 2013, the other defendants filed a petition for review with the U.S. Supreme Court. CenterPoint Energy believes that CES is not a proper defendant in this case and will continue to pursue a dismissal. CenterPoint Energy does not expect the ultimate outcome of this matter to have a material impact on its financial condition, results of operations or cash flows.

## Environmental Matters

Manufactured Gas Plant Sites. CERC and its predecessors operated manufactured gas plants (MGPs) in the past. In Minnesota, CERC has completed remediation on two sites, other than ongoing monitoring and water treatment. There are five remaining sites in CERC’s Minnesota service territory. CERC believes that it has no liability with respect to two of these sites.

As of December 31, 2013, CERC had recorded a liability of $14 million for remediation of these Minnesota sites. The estimated range of possible remediation costs for the sites for which CERC believes it may have responsibility was $6 million to



$41 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 be dependent upon the number of sites to be remediated, the participation of other potentially responsible parties (PRPs), if any, and the remediation methods used. The Minnesota Public Utilities Commission includes approximately $285,000 annually in rates to fund normal ongoing remediation costs. As of December 31, 2013, CERC had collected $6.3 million from insurance companies to be used for future environmental remediation.

In addition to the Minnesota sites, the United States Environmental Protection Agency 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. CERC and CenterPoint Energy do not expect the ultimate outcome of these investigations will have a material adverse impact on the financial condition, results of operations or cash flows of either CenterPoint Energy or CERC.

Asbestos. Some facilities owned by CenterPoint Energy contain or have contained asbestos insulation and other asbestos-containing materials. CenterPoint Energy or its subsidiaries have been named, along with numerous others, as a defendant in lawsuits filed by a number of individuals who claim injury due to exposure to asbestos. Some of the claimants have worked at locations owned by subsidiaries of CenterPoint Energy, but most existing claims relate to facilities previously owned by CenterPoint Energy's subsidiaries. CenterPoint Energy anticipates that additional claims like those received may be asserted in the future. In 2004 and early 2005, CenterPoint Energy sold its generating business, to which most of these claims relate, to a company which is now an affiliate of NRG. Under the terms of the arrangements regarding separation of the generating business from CenterPoint Energy and its sale of that business, ultimate financial responsibility for uninsured losses from claims relating to the generating business has been assumed by the NRG affiliate, but CenterPoint Energy has agreed to continue to defend such claims to the extent they are covered by insurance maintained by CenterPoint Energy, subject to reimbursement of the costs of such defense by the NRG affiliate. Although their ultimate outcome cannot be predicted at this time, CenterPoint Energy intends to continue vigorously contesting claims that it does not consider to have merit and, based on its experience to date, 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 on property where its subsidiaries conduct or 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, based on its experience to date, 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 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.

## (e) Guarantees

Prior to the distribution of CenterPoint Energy’s ownership in RRI to its shareholders, CERC had guaranteed certain contractual obligations of what became RRI’s trading subsidiary. When the companies separated, RRI agreed to secure CERC against obligations under the guarantees RRI had been unable to extinguish by the time of separation. Pursuant to such agreement, as amended in December 2007, RRI (now GenOn) agreed to provide to CERC cash or letters of credit as security against CERC’s obligations under its remaining guarantees for demand charges under certain gas transportation agreements if and to the extent changes in market conditions expose CERC to a risk of loss on those guarantees based on an annual calculation, with any required collateral to be posted each December. The undiscounted maximum potential payout of the demand charges under these transportation contracts, which will be in effect until 2018, was approximately $58 million as of December 31, 2013. Based on market conditions in the fourth quarter of 2013 at the time the most recent annual calculation was made under the agreement,



GenOn was not obligated to post any security. If GenOn should fail to perform the contractual obligations, CERC could have to honor its guarantee and, in such event, any collateral then provided as security may be insufficient to satisfy CERC’s obligations.

CenterPoint Energy, Inc. has provided guarantees (CenterPoint Midstream Guarantees) with respect to the performance of certain obligations of Enable under long-term gas gathering and treating agreements with an indirect wholly owned subsidiary of Encana Corporation and an indirect wholly owned subsidiary of Royal Dutch Shell plc. As of December 31, 2013, CenterPoint Energy, Inc. had guaranteed Enable's obligations up to an aggregate amount of $100 million under these agreements. Under the terms of the omnibus agreement entered into in connection with the closing of the formation of Enable, Enable and CenterPoint Energy, Inc. have agreed to use commercially reasonable efforts and cooperate with each other to terminate the CenterPoint Midstream Guarantees and to release CenterPoint Energy, Inc. from such guarantees by causing Enable or one of its subsidiaries to enter into substitute guarantees or to assume the CenterPoint Midstream Guarantees as applicable. CERC Corp. has also provided a guarantee of collection of Enable's obligations under its $1.05 billion three-year unsecured term loan facility, which guarantee is subordinated to all senior debt of CERC Corp.

As of December 31, 2013, no amounts have been recorded related to the guarantees described above in the Consolidated Balance Sheets.

## (17) 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. The accounting policies of the business segments are the same as those described in the summary of significant accounting policies except that some executive benefit costs have not been allocated to business segments. CenterPoint Energy uses operating income as the measure of profit or loss for its business segments.

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 (CenterPoint Houston) 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 primarily of CenterPoint Energy’s investment in Enable and its retained interest in SESH. Other Operations consists primarily of other corporate operations which support all of CenterPoint Energy’s business operations.

Prior to May 1, 2013, CenterPoint Energy also reported an Interstate Pipelines business segment, which included CenterPoint Energy’s interstate natural gas pipeline operations, and a Field Services business segment, which included CenterPoint Energy’s non-rate regulated natural gas gathering, processing and treating operations. As previously disclosed, the formation of Enable



closed on May 1, 2013. Enable now owns substantially all of CenterPoint Energy’s former Interstate Pipelines and Field Services business segments, except for the retained interest in SESH. As a result, effective May 1, 2013, CenterPoint Energy reports equity earnings associated with its interest in Enable and equity earnings associated with its retained interest in SESH under a new Midstream Investments segment, and no longer has Interstate Pipelines and Field Services reporting segments prospectively. See Note 9 for further discussion on Enable formation.

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.

Financial data for business segments and products and services are as follows (in millions):

(1) Sales to affiliates of NRG in 2013, 2012 and 2011 represented approximately $658 million, $648 million and $594 million, respectively, of CenterPoint Houston's transmission and distribution revenues. Sales to affiliates of Energy Future Holdings Corp. in 2013, 2012 and 2011 represented approximately $167 million, $162 million and $182 million, respectively, of CenterPoint Houston's transmission and distribution revenues.

Interstate Pipelines' investment in SESH was $404 million and $409 million as of December 31, 2012 and 2011 and is included in Investment in unconsolidated affiliates. As discussed above, effective May 1, 2013, CenterPoint Energy reports equity earnings



associated with its interest in Enable and equity earnings associated with its retained interest in SESH under a new Midstream Investments segment, and no longer has an Interstate Pipelines reporting segment prospectively.

(3) Field Services recorded equity income of $5 million and $9 million for the years ended December 31, 2012 and 2011, respectively, from its interest in Waskom. These amounts are included in Equity in earnings of unconsolidated affiliates under the Other Income (Expense) caption. Field Services' investment in the jointly-owned gas processing plant was $63 million as of December 31, 2011 and is included in Investment in unconsolidated affiliates. Beginning on August 1, 2012, financial results for Waskom are included in operating income due to the July 31, 2012 purchase of the 50% interest in Waskom that CenterPoint Energy did not already own. CenterPoint Energy contributed 100% interest in Waskom to Enable on May 1, 2013. Effective May 1, 2013, CenterPoint Energy reports equity earnings associated with its interest in Enable under a new Midstream Investments segment, and no longer has a Field Services reporting segment prospectively.

# CENTERPOINT ENERGY, INC.
SCHEDULE I — NOTES TO CONDENSED FINANCIAL INFORMATION (PARENT COMPANY)

(1) Background. The condensed parent company financial statements and notes of CenterPoint Energy, Inc. (CenterPoint Energy) should be read in conjunction with the consolidated financial statements and notes of CenterPoint Energy, Inc. and subsidiaries appearing in the Annual Report on Form 10-K. Credit facilities at CenterPoint Energy Houston Electric, LLC (CenterPoint Houston) and CenterPoint Energy Resources Corp., indirect wholly owned subsidiaries of CenterPoint Energy, limit debt, excluding transition and system restoration bonds, as a percentage of their consolidated capitalization to 65%. These covenants could restrict the ability of these subsidiaries to distribute dividends to CenterPoint Energy.

(2) New Accounting Pronouncements. In February 2013, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update No. 2013-02, “Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income” (ASU 2013-02). The objective of ASU 2013-02 is to improve the transparency of changes in other comprehensive income and items reclassified out of Accumulated Other Comprehensive Income in financial statements. This new guidance is effective for a reporting entity’s first reporting period beginning after December 15, 2012 and should be applied prospectively. CenterPoint Energy’s adoption of this new guidance on January 1, 2013 did not have a material impact on its financial position, results of operations or cash flows.

In December 2011 and January 2013, the FASB issued Accounting Standards Update No. 2011-11, “Disclosures About Offsetting Assets and Liabilities” (ASU 2011-11) and No. 2013-01, “Clarifying the Scope of Disclosures About Offsetting Assets and Liabilities” (ASU 2013-01), respectively. The objective of ASU 2011-11 is to enhance disclosures about the nature of an entity’s rights of setoff and related arrangements associated with its financial instruments and derivative instruments. The objective of ASU 2013-01 is to clarify which instruments and transactions are subject to ASU 2011-11. Both ASU 2011-11 and ASU 2013-01 are effective for a reporting entity’s first reporting period beginning on or after January 1, 2013 and should be applied retrospectively. CenterPoint Energy’s adoption of this new guidance on January 1, 2013 did not have a material impact on its financial position, results of operations or cash flows.

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.

(3) Long-term Debt. As of December 31, 2013 and 2012, CenterPoint Energy had no borrowings and approximately $6 million and $7 million, respectively, of outstanding letters of credit under its $1.2 billion credit facility. There was no commercial paper outstanding that would have been backstopped by CenterPoint Energy’s $1.2 billion credit facility as of December 31, 2013 and 2012. CenterPoint Energy was in compliance with all financial debt covenants as of December 31, 2013.

CenterPoint Energy’s $1.2 billion revolving credit facility, which is scheduled to terminate on September 9, 2018, can be drawn at the London Interbank Offered Rate (LIBOR) plus 125 basis points based on CenterPoint Energy’s current credit ratings. The revolving credit facility contains a financial covenant which limits CenterPoint Energy’s consolidated debt (excluding transition and system restoration bonds) to an amount not to exceed 65% of CenterPoint Energy’s consolidated capitalization. The financial covenant limit will temporarily increase from 65% to 70% if CenterPoint Houston experiences damage from a natural disaster in its service territory and CenterPoint Energy certifies to the administrative agent that CenterPoint Houston has incurred system restoration costs reasonably likely to exceed $100 million in a consecutive twelve-month period, all or part of which CenterPoint Houston 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’s maturities of long-term debt, excluding the indexed debt securities obligation, are $269 million in 2015, $250 million in 2017 and $350 million in 2018. There are no maturities of long-term debt in 2014 or 2016.

(4) Guarantees. CenterPoint Energy, Inc. has provided guarantees (CenterPoint Midstream Guarantees) with respect to the performance of certain obligations of Enable under long-term gas gathering and treating agreements with an indirect wholly owned subsidiary of Encana Corporation and an indirect wholly owned subsidiary of Royal Dutch Shell plc. As of December 31, 2013, CenterPoint Energy, Inc. had guaranteed Enable’s obligations up to an aggregate amount of $100 million under these agreements. Under the terms of the omnibus agreement entered into in connection with the closing of the formation of Enable, Enable and CenterPoint Energy, Inc. have agreed to use commercially reasonable efforts and cooperate with each other to terminate the CenterPoint Midstream Guarantees, and to release CenterPoint Energy, Inc. from such guarantees by causing Enable or one of its subsidiaries to enter into substitute guarantees or to assume the CenterPoint Midstream Guarantees as applicable.
