COMBINED NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(1) Background and Basis of Presentation

No Registrant makes any representations as to the information related solely to CenterPoint Energy or the subsidiaries of CenterPoint Energy other than itself.

General.Included in this combined Form 10-Q are the Interim Condensed Financial Statements of CenterPoint Energy, Houston Electric.Electric and CERC, which are referred to collectively as the Registrants. The Combined Notes to the Unaudited Condensed Consolidated Financial Statements apply to all Registrants unless otherwise indicated. The Interim Condensed Financial Statements are unaudited, omit certain financial statement disclosures and should be read with each of the Registrants’ 2017 Form 10-K.

Background.Houston Electric is an indirect, wholly-owned subsidiary of CenterPoint Energy, Inc., is a public utility holding company.company and owns interests in Enable as described below. CenterPoint Energy’s operating subsidiaries, Houston Electric providesand CERC, own and operate electric transmission and distribution servicesand natural gas distribution facilities and supply natural gas to REPs serving over 2.4 million meteredcommercial and industrial customers and electric and natural gas utilities.

Houston Electric engages in the electric transmission and distribution business in the Texas Gulf Coast area that includes the city of Houston. As of March 31, 2018, Houston Electric had the following subsidiaries: Bond Company II, Bond Company III, Restoration Bond CompanyHouston; and Bond Company IV.  

CERC Corp. (i) owns and operates natural gas distribution systems in six states and (ii) obtains and offers competitive variable and fixed-price physical natural gas supplies and services primarily to commercial and industrial customers and electric and natural gas utilities in 33 states through its wholly-owned subsidiary, CES.

As of March 31,September 30, 2018, CenterPoint Energy, indirectly through CNP Midstream, owned approximately 54.0% of the common units representing limited partner interests in Enable, 50% of the management rights and 40% of the incentive distribution rights in Enable GP and also directly owned an aggregate of 14,520,000 Enable Series A Preferred Units. Enable owns, operates and develops natural gas and crude oil infrastructure assets.

On September 4, 2018, CERC entered into a Contribution Agreement, by and between CERC and CNP Midstream, a new subsidiary formed by CERC in June 2018, pursuant to which CERC contributed its equity investment in Enable consisting of Enable common units and its interests in Enable GP, to CNP Midstream (collectively, the Enable Contribution). Immediately following the Enable Contribution, CERC distributed all of its interest in CNP Midstream to Utility Holding, CERC’s sole stockholder and a wholly-owned subsidiary of CenterPoint Energy. Utility Holding then distributed all of its interest in CNP Midstream to CenterPoint Energy, its sole member (collectively with the Enable Contribution, the Internal Spin). CERC executed the Internal Spin to, among other things, enhance the access of CERC and CenterPoint Energy to low cost debt and equity through increased transparency and understandability of the financial statements, improve CERC’s credit quality by eliminating the exposure to Enable’s midstream business and provide clarity of internal reporting and performance metrics to enhance management’s decision making for CERC and CNP Midstream.

As a result of the Internal Spin, CERC’s equity in earnings in Enable and related income taxes have been classified as discontinued operations in CERC’s Interim Condensed Financial Statements. For further information regarding the Internal Spin and CERC’s presentation of discontinued operations, see Note 9.

As of September 30, 2018, CenterPoint Energy and Houston Electric had VIEs consisting of the Bond Companies, which it consolidates.are consolidated. 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 and Houston Electric have no recourse to any assets or revenues of the Bond Companies. The bonds issued by these VIEs are only payable only from and secured by transition and system restoration property, and the bondholders have no recourse to the general credit of CenterPoint Energy or Houston Electric.

Basis of Presentation.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.

Houston Electric’sThe Interim Condensed Financial Statements reflect all normal recurring adjustments that are, in the opinion of management, necessary to present fairly the financial position, results of operations and cash flows for the respective periods. Amounts reported in Houston Electric’sthe Condensed Statements of Consolidated Income are not necessarily indicative of amounts expected for a full-year period due to the effects of, among other things, (a) seasonal fluctuations in demand for energy and energy services, (b) changes in energy commodity prices, (c) timing of maintenance and other expenditures and (c)(d) acquisitions and dispositions of businesses, assets and other interests. Certain prior year amounts have been reclassified to conform to the current year presentation. See Notes 2 and 9 for further discussion.

ASU 2014-09- Revenue from Contracts with Customers (Topic 606) and related amendments 
This standard provides a comprehensive new revenue recognition model that requires revenue to be recognized in a manner that depicts the transfer of goods or services to a customer at an amount that reflects the consideration expected to be received in exchange for those goods or services.
Transition method: modified retrospective

 January 1, 2018 Houston Electric added a revenue recognition footnote (Note 3) to addressNote 4 addresses the disclosure requirements, and itrequirements. Adoption of the standard did not identifyresult in significant changes to revenue recognition. A substantial amount of Houston Electric’sthe Registrants’ revenues are tariff and/or derivative based, which were not significantly impacted by these ASUs.
ASU 2017-05- Other Income-Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20): Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets 
This standard clarifies when and how to apply ASC 610-20, which was issued as part of ASU 2014-09. It amends or supersedes the guidance in ASC 350 and ASC 360 on determining a gain or loss recognized upon the derecognition of nonfinancial assets.

ASU 2018-03-Technical Corrections and Improvements to Financial Instruments-Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities
 
This standard requires equity investments that do not result in consolidation and are not accounted for under the equity method to be measured at fair value and to recognize any changes in fair value in net income unless the investments qualify for the new practicability exception. It does not change the guidance for classifying and measuring investments in debt securities and loans. It also changes certain disclosure requirements and other aspects related to recognition and measurement of financial assets and financial liabilities.

The Registrants elected the practicability exception for investments without a readily determinable fair value to be measured at cost. This includes the Enable Series A Preferred Units owned by CenterPoint Energy, which were previously accounted for under the cost method. See Note 9 for further discussion.
ASU 2016-15- Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments 
This standard provides clarifying guidance on the classification of certain cash receipts and payments in the statement of cash flows and eliminates the variation in practice related to such classifications.

ASU 2016-18- Statement of Cash Flows (Topic 230): Restricted Cash 
This standard requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, restricted cash and restricted cash equivalents. As a result, the statement of cash flows will no longer present transfers between cash and cash equivalents and restricted cash and restricted cash equivalents. When cash, cash equivalents, restricted cash and restricted cash equivalents are presented in more than one line item on the balance sheet, the new guidance requires a reconciliation of the totals in the statement of cash flows to the related captions in the balance sheet.
Transition method: retrospective
 January 1, 2018 The adoption of this standard did not have an impact on Houston Electric’sthe Registrants’ financial position, results of operations or disclosures. However, the statementCenterPoint Energy’s and Houston Electric’s Condensed Statements of cash flows isConsolidated Cash Flows are reconciled to cash, cash equivalents and restricted cash, resulting in a decrease in investing activities of $2 million and an increase in investing activities of $4$8 million for the threenine months ended March 31,September 30, 2018 and 2017, respectively. See Note 17 for further discussion.
ASU 2017-01- Business Combinations (Topic 805): Clarifying the Definition of a Business 
This standard revises the definition of a business. If substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets, then under ASU 2017-01, the asset or group of assets is not a business. The guidance also requires a business to include at least one substantive process and narrows the definition of outputs to be more closely aligned with how outputs are described in ASC 606.
Transition method: prospective
 January 1, 2018 The adoption of this revised definition will reduce the number of transactions that are accounted for as a business combination, and therefore may have a potential impact on Houston Electric’sthe Registrants’ accounting for future acquisitions.
ASU 2017-04- Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment
This standard eliminates Step 2 of the goodwill impairment test, which required a hypothetical purchase price allocation. A goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill.
Transition method: prospective
January 1, 2018The adoption of this standard will have an impact on CenterPoint Energy’s and CERC’s future calculation of goodwill impairments if an impairment is identified.
ASU 2017-07- Compensation-Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost 
This standard requires an employer to report the service cost component of the net periodic pension cost and postretirement benefit cost in the same line item(s) as other employee compensation costs arising from services rendered during the period; all other components will be presented separately from the line item(s) that includes the service cost and outside of any subtotal of operating income. In addition, only the service cost component will be eligible for capitalization in assets.

Other components previously capitalized in assets will be recorded as regulatory assets in the Registrants’ rate-regulated businesses, prospectively.
ASU 2017-09- Compensation-Stock Compensation (Topic 718): Scope of Modification Accounting
This standard clarifies when changes to the terms or conditions of a share-based payment award must be accounted for as a modification. Entities will apply the modification accounting guidance if the value, vesting conditions or classification of the award changes.
Transition method: prospective
January 1, 2018The adoption of this standard will have an impact on CenterPoint Energy’s accounting for future changes to share-based payment awards.
ASU 2017-12- Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities
This standard expands an entity’s ability to hedge and account for risk components, reduces the complexity of applying certain aspects of hedge accounting and updates the presentation and disclosure requirements. The guidance eliminates the requirement to separately measure and report hedge ineffectiveness.
Transition method: cumulative-effect adjustment for elimination of the separate measurement of ineffectiveness; prospective for presentation and disclosure
July 1, 2018
Applicable January 1, 2018
The adoption of this standard did not have a material impact on the Registrants’ financial position, results of operations or cash flows. As a result of the adoption, the Registrants will no longer recognize ineffectiveness for derivatives designated as cash flow hedges; all changes in fair value will flow through other comprehensive income. As the Registrants did not have existing cash flow hedges as of the initial application date and the adoption date, no cumulative effective adjustment was recorded. Note 7 reflects disclosures modified upon adoption.
ASU 2018-13- Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement
This standard eliminates, modifies and adds certain disclosure requirements for fair value measurements.
Transition method: prospective for additions and one modification and retrospective for all other amendments
Adoption of eliminations and modifications as of September 30, 2018; Additions will be adopted January 1, 2020The adoption of this standard did not impact the Registrants’ financial position, results of operations or cash flows. Note 8 reflects the disclosures modified upon adoption.

(3) Pending Merger with Vectren (CenterPoint Energy)

On April 21, 2018, CenterPoint Energy entered into the Merger Agreement. Under the terms of the Merger Agreement, CenterPoint Energy will acquire Vectren for approximately $6 billion in cash. Upon closing, Vectren will become a wholly-owned subsidiary of CenterPoint Energy.

Pursuant to the Merger Agreement, upon the closing of the Merger, each share of Vectren common stock issued and outstanding immediately prior to the closing will be converted automatically into the right to receive $72.00 in cash per share. During August and October 2018, CenterPoint Energy completed its permanent financing for the Merger through offerings of the Series A Preferred Stock, depositary shares, each representing a 1/20th interest in a share of Series B Preferred Stock, Common Stock and unsecured senior notes. See Notes 12 and 19 for further details regarding the Merger financings. As of September 30, 2018, Vectren and its subsidiaries had outstanding $325 million of short-term debt and $2.0 billion of long-term debt, including current maturities. It is anticipated that Vectren and its subsidiaries will have approximately $2.5 billion of outstanding short-term and long-term debt as of December 31, 2018.

Consummation of the Merger is conditioned upon approval by federal regulatory commissions, orders from state regulatory commissions, expiration or termination of the applicable HSR waiting period and approval of the Merger by Vectren shareholders. In June 2018, CenterPoint Energy and Vectren (i) submitted their filings with the FERC and the FCC, (ii) submitted their filings with the FTC pursuant to the HSR Act and (iii) initiated informational proceedings with regulators in Indiana and Ohio. On June 26, 2018, CenterPoint Energy and Vectren received notice from the FTC granting early termination of the waiting period under the HSR Act in connection with the Merger. On August 28, 2018, shareholders of Vectren, during a special shareholders’ meeting, approved the Merger. The FCC granted approvals on July 20 and 24, 2018, and on October 5, 2018, the FERC authorized the Merger. A hearing before the Indiana Utility Regulatory Commission was held on October 17, 2018 with respect to the Merger. CenterPoint Energy has requested a final order for this proceeding by the end of January or early February 2019.

The Merger Agreement contains termination rights for both CenterPoint Energy and Vectren, and provides that, upon termination of the Merger Agreement under specified circumstances, CenterPoint Energy would be required to pay a termination fee of $210 million to Vectren or Vectren would be required to pay CenterPoint Energy a termination fee of $150 million.

Subject to receipt of required regulatory and statutory approvals and satisfaction and/or waiver of the closing conditions, CenterPoint Energy continues to anticipate closing the Merger in the first quarter of 2019.

(4) Revenue Recognition

Houston ElectricThe Registrants adopted ASC 606 and all related amendments on January 1, 2018 using the modified retrospective method for those contracts that were not completed as of the date of adoption. Application of the new revenue standard did not result in a cumulative effect adjustment to the opening balance of retained earnings. The comparative information has not been restated and

continues to be reported under the accounting standards in effect for those periods. The adoption of the new standard did not have a material impact on Houston Electric’sthe Registrants’ financial position, results of operations or cash flows.

In accordance with ASC 606, revenue is recognized when a customer obtains control of promised goods or services. The amount of revenue recognized reflects the consideration to which Houston Electric expectsthe Registrants expect to be entitled to receive in exchange for these goods or services. Contract assets and liabilities are not material.

Houston Electric recognizesThe Registrants recognize ARP revenue as other revenues when the PUCT-specifiedregulator-specified conditions for recognition have been met. Upon recovery of ARP revenue through incorporation in rates charged for utility service to customers, ARP revenue is reversed and recorded as revenue from contracts with customers. The recognition of ARP revenues and the reversal of ARP revenues upon recovery through rates charged for utility service may not occur in the same period.

for utility service to customers, ARP revenue is reversed and recorded as revenue from contracts with customers. The recognition of ARP revenues and the reversal of ARP revenues upon recovery through rates charged for utility service may not occur in the same period.

Revenues from Contracts with Customers

Electric Transmission & Distribution. Houston Electric distributes electricity to customers over time and customers consume the electricity when delivered. Revenue, consisting of both volumetric and fixed tariff rates set by the PUCT, is recognized as electricity is delivered and represents amounts both billed and unbilled. Discretionary services requested by customers are provided at a point in time with control transferring upon the completion of the service. Revenue for discretionary services is recognized upon completion of service based on the tariff rates set by the PUCT. Payments for electricity distribution and discretionary services are aggregated and received on a monthly basis. Houston Electric performs transmission services over time as a stand-ready obligation to provide a reliable network of transmission systems. Revenue is recognized upon time elapsed, and the monthly tariff rate set by the PUCT. Payments are received on a monthly basis.

Natural Gas Distribution. CERC distributes and transports natural gas to customers over time, and customers consume the natural gas when delivered. Revenue, consisting of both volumetric and fixed tariff rates set by the state governing agency for that service area, is recognized as natural gas is delivered and represents amounts both billed and unbilled. Discretionary services requested by the customer are satisfied at a point in time and revenue is recognized upon completion of service and the tariff rates set by the applicable state regulator. Payments of natural gas distribution, transportation and discretionary services are aggregated and received on a monthly basis.

Energy Services. The majority of CES natural gas sales contracts are considered a derivative, as the contracts typically have a stated minimum or contractual volume of delivery.

For contracts in which CES delivers the full requirement of the natural gas needed by the customer and a volume is not stated, a contract as defined under ASC 606 is created upon the customer’s exercise of its option to take natural gas. CES supplies natural

gas to retail customers over time as customers consume the natural gas when delivered. For wholesale customers, CES supplies natural gas at a point in time because the wholesale customer is presumed to have storage capabilities. Control is transferred to both types of customers upon delivery of natural gas. Revenue is recognized on a monthly basis based on the estimated volume of natural gas delivered and the price agreed upon with the customer. Payments are received on a monthly basis.

AMAs are natural gas sales contracts under which CES also assumes management of a customer’s physical storage and/or transportation capacity. AMAs have two distinct performance obligations, which consist of natural gas sales and natural gas delivery because delivery could occur separate from the sale of natural gas (e.g., from storage to customer premises). Most AMAs’ natural gas sales performance obligations are accounted for as embedded derivatives. The transaction price is allocated between the sale of natural gas and the delivery based on the stand-alone selling price as stated in the contract. CES performs natural gas delivery over time as customers take delivery of the natural gas and recognizes revenue on an aggregated monthly basis based on the volume of natural gas delivered and the fees stated within the contract. Payments are received on a monthly basis.

Practical Expedients and Exemption. Sales taxes and other similar taxes collected from customers are excluded from the transaction price.

(1)Current regulatory assets are included in Prepaid expenses and other current assets in the Registrants’ Condensed Consolidated Balance Sheets.

(2)The unrecognized equity return will be recognized as it is recovered in rates through 2024. During the three months ended March 31,September 30, 2018 and 2017, CenterPoint Energy and Houston Electric recognized approximately $21$17 million and $7$13 million, respectively, of the allowed equity return. During the nine months ended September 30, 2018 and 2017, CenterPoint Energy and Houston Electric recognized approximately $62 million and $30 million, respectively, of the allowed equity return. The timing of CenterPoint Energy’s and Houston Electric’s recognition of the equity return will vary each period based on amounts actually collected during the period. The actual amounts recognized are adjusted at least annually to correct any over-collections or under-collections during the preceding 12 months.

(2)(3)Houston ElectricIncludes a portion of NGD’s actuarially determined pension and other postemployment expense in excess of the amount being recovered through rates that is being deferred for rate making purposes, of which $4 million and $7 million as of September 30, 2018 and December 31, 2017, respectively, were not earning a return.

(4)The Registrants are not earning a return on its Hurricane Harvey restoration costs.

(3)(5)The EDIT and deferred revenues will be recovered or refunded to customers as required by tax and regulatory authorities.

(4)(6)Other long-term regulatory assets that are not earning a return were not material as of March 31,September 30, 2018 and December 31, 2017.

(5)(7)Current regulatory liabilities are included in Other current liabilities in Houston Electric’seach of the Registrants’ respective Condensed Consolidated Balance Sheets.


(6)(7) Derivative Instruments

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

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

The Registrants’ 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.

(a)Non-Trading Activities

Commodity Derivative Instruments. CenterPoint Energy and CERC, through CES, enter into certain derivative instruments to mitigate the effects of commodity price movements. Certain financial instruments used to hedge portions of the natural gas inventory of the Energy Services business segment are designated as fair value hedges for accounting purposes. All other financial instruments do not qualify or are not designated as cash flow or fair value hedges.

Weather Hedges. CenterPoint Energy and CERC have weather normalization or other rate mechanisms that mitigate the impact of weather on NGD in Arkansas, Louisiana, Mississippi, Minnesota and Oklahoma. NGD and electric operations in Texas do not have such mechanisms, although fixed customer charges are historically higher in Texas for NGD compared to its other jurisdictions. As a result, fluctuations from normal weather may have a positive or negative effect on NGD’s results in Texas and on electric operations’ results in its service territory.

CenterPoint Energy and CERC, as applicable, enter into winter season weather hedges from time to time for certain NGD jurisdictions and electric operations’ service territory to mitigate the effect of fluctuations from normal weather on results of operations and cash flows. These weather hedges are based on heating degree days at 10-year normal weather. Houston Electric does not enter into weather hedges.

The table below summarizes CenterPoint Energy’s and CERC’s current weather hedge gain (loss) activity:

(1)Weather hedge gains (losses) are recorded in Revenues in the Condensed Statements of Consolidated Income.

Cash Flow Hedging of Interest Expense. From time to time, the Registrants enter into forward interest rate agreements with certain counterparties designated as cash flow hedges. The objective of these cash flow hedges is to reduce exposure to variability in cash flows related to interest payments on anticipated future fixed rate debt offerings or other exposure to variable rate debt. In October 2018, Houston Electric entered into an additional $100 million of notional amount on forward interest rate agreements

classified as cash flow hedges. As of September 30, 2018 and December 31, 2017, the total outstanding notional amount of Houston Electric’s forward interest rate agreements related to cash flow hedges was $100 million and $-0-, respectively. The maximum length of time over which Houston Electric is exposed to the variability in future cash flows of the forecasted debt offerings is less than 12 months.

Economic Hedging of Interest Rate Risk. From time to time, the Registrants may enter into forward interest rate agreements with certain counterparties designated as economic hedges. The objective of these economic hedges is to offset any interest rate risk borne by one or more of the Registrants in connection with an anticipated future fixed rate debt offering or other exposure to variable rate debt. As of September 30, 2018 and December 31, 2017, the total outstanding notional amount of CenterPoint Energy’s forward interest rate agreements related to economic hedges in connection with the permanent financing for the Merger was $200 million and $-0-, respectively. As of September 30, 2018 and December 31, 2017, the fair value of interest rate derivatives was less than $1 million and therefore was not included in the tabular presentation below.

(1)The fair value shown for natural gas contracts is comprised of derivative gross volumes totaling 1,865 Bcf or a net 310 Bcf long position and 1,795 Bcf or a net 224 Bcf long position as of September 30, 2018 and December 31, 2017, respectively.  Certain natural gas contracts hedge basis risk only and lack a fixed price exposure.

(2)Natural gas contracts are presented on a net basis in the Condensed Consolidated Balance Sheets as they 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 Condensed Consolidated Balance Sheets. The net of total non-trading natural gas derivative assets and liabilities was a $72 million asset and a $130 million asset as of September 30, 2018 and December 31, 2017, respectively, as shown on CenterPoint Energy’s and CERC’s Condensed Consolidated Balance Sheets (and as detailed in the Offsetting of Natural Gas Derivative Assets and Liabilities table below), and was comprised of the natural gas contracts derivative assets and liabilities separately shown above, impacted by collateral netting of $21 million and $19 million, respectively.

(3)Derivative Assets and Derivative Liabilities include no material amounts related to physical forward transactions with Enable.

(1)As a result of the adoption of ASU 2017-12 effective January 1, 2018 (see Note 2 for additional information), CenterPoint Energy and CERC exclude from their assessment of hedge effectiveness the natural gas market price difference between locations of the hedged inventory and the delivery location specified in the hedge instruments. Prior to the adoption of this accounting guidance, the timing difference between the spot price and the futures price, as well as the difference between the timing of the settlement of the futures and the valuation of the underlying physical commodity, was excluded from the assessment of effectiveness for CenterPoint Energy’s and CERC’s existing fair value hedges and will continue to be excluded from the assessment of hedge effectiveness. CenterPoint Energy and CERC elected to continue to

immediately recognize amounts excluded from hedge effectiveness in their respective Condensed Statements of Consolidated Income.

(2)Income statement impact associated with cash flow hedge activity is related to gains and losses reclassified from accumulated other comprehensive income into income. Amounts are immaterial for the Registrants for both the three and nine months ended September 30, 2018 and 2017, respectively.

(1)Gains and losses are reclassified from accumulated other comprehensive income into income when the hedged transactions affect earnings. The reclassification amounts are included in Interest and other finance charges in the Condensed Statements of Consolidated Income. Amounts are less than $1 million for each of the three and nine months ended September 30, 2018 and 2017. Over the next twelve months, estimated amortization of accumulated other comprehensive income into related income is expected to be immaterial.

(c)Credit Risk Contingent Features

CenterPoint Energy and CERC enter into financial derivative contracts containing material adverse change provisions.  These provisions could require CenterPoint Energy or CERC to post additional collateral if the S&P or Moody’s credit ratings of CenterPoint Energy, Inc. or its subsidiaries, including CERC Corp., are downgraded.

(8) Fair Value Measurements

Assets and liabilities that are recorded at fair value in the Registrants’ Condensed 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 investments listedexchange-traded derivatives and equity securities, as well as natural gas inventory that has been designated as the hedged item in active markets.  As of March 31, 2018 and December 31, 2017, Houston Electric held Level 1 investments of $53 million and $51 million, respectively, which were primarily investments in money market funds and are included in other current assets and other assets in the Condensed Consolidated Balance Sheets.

a fair value hedge.

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. Houston Electric had noFair 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 the Registrants’ Level 2 natural gas derivative assets or liabilitiesliabilities. CenterPoint Energy’s Level 2 indexed debt securities derivative is valued using an option model and a discounted cash flow model, which uses projected dividends on the ZENS-Related Securities and a discount rate as of either March 31, 2018 or December 31, 2017.observable inputs.

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 Houston Electric’sthe Registrants’ judgments about the assumptions market participants would use in determining fair value.  Houston Electric had nopricing the asset or liability since limited market data exists. The Registrants develop these inputs based on the best information available, including the Registrants’ own data. A market approach is utilized to value the Registrants’ Level 3 assets or liabilities. As of September 30, 2018, CenterPoint Energy’s and CERC’s Level 3 assets and liabilities are comprised of physical natural gas forward contracts and options. Level 3 physical natural gas forward contracts and options include illiquid forward price curve locations (ranging from $1.28 to $6.88 per MMBtu) as an unobservable input. CenterPoint Energy’s and CERC’s Level 3 physical natural gas forward contracts and options derivative assets and liabilities consist of both long and short positions (forwards and options). Forward price decreases (increases) as of either March 31,September 30, 2018 or December 31, 2017. would have resulted in lower (higher) values, respectively, for long forwards and options and higher (lower) values, respectively, for short forwards and options.

Houston Electric determinesThe Registrants determine the appropriate level for each financial asset and liability on a quarterly basisbasis. The Registrants also recognize purchases of Level 3 financial assets and recognizes transfers between levelsliabilities at their fair market value at the end of the reporting period. For the three months ended March 31, 2018, there were no transfers between levels.

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

Estimated Fair Value of Financial Instruments

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

Upon the adoption of ASU 2014-09 and ASU 2017-05 on January 1, 2018, CenterPoint Energy evaluated transactions in the investment in Enable that occurred prior to Houston Electric using methods that management believes are reasonable. These methods include negotiated usage rates, dedicated asset assignmentJanuary 1, 2018 (the effective date) and proportionate corporate formulas based on operating expenses, assets, gross margin, employees andconcluded a compositecumulative effect adjustment to the opening balance of assets, gross margin and employees. CERC provides certain services to Houston Electric. These services are billed at actual cost, either directly or as an allocation and include line locating and other miscellaneous services. Additionally, Houston Electric provides a number of services to CERC.

CenterPoint Energy’s maximum exposure to loss related to Enable, a VIE in which CenterPoint Energy is not the primary beneficiary, is limited to the equity investment, the Series A Preferred Unit investment and outstanding current accounts receivable from Enable.

Amounts chargedOn September 4, 2018, CERC completed the Internal Spin of its equity investment in Enable and Enable GP. The Internal Spin has been accounted for under the guidance for transactions between entities under common control. As of September 4, 2018, CERC derecognized its investment in Enable at carrying value on the date of distribution of $2.4 billion, net of deferred income taxes of $974 million, and CNP Midstream recorded the net asset contribution from CERC at CERC’s carrying value. Neither CERC nor CNP Midstream recognized a gain or loss upon the distribution or contribution, respectively, of net assets involved in the Internal Spin. In connection with the Internal Spin, CenterPoint Energy, through Utility Holding, made a $600 million capital contribution to CERC, which was used by CERC to repay outstanding indebtedness that historically supported CERC’s legacy midstream assets. See Note 18 for further discussion.

Discontinued Operations (CERC):

The Internal Spin represents a significant strategic shift that has a material effect on CERC’s operations and financial results and, as a result, CERC’s distribution of its equity investment in Enable met the criteria for discontinued operations classification. CERC has no continuing involvement in the equity investment of Enable. Therefore, CERC’s equity in earnings and related income taxes have been classified as Income from discontinued operations, net of tax, in CERC’s Condensed Statements of Consolidated Income for the periods presented. CERC’s equity method investment and related deferred income tax liabilities have been classified as Investment in unconsolidated affiliate - discontinued operations and Deferred income taxes, net - discontinued operations, respectively, in CERC’s Condensed Consolidated Balance Sheets for the periods presented. The following table presents amounts included in Income from discontinued operations, net of tax in CERC’s Condensed Statements of Consolidated Income.

(8)(10) Goodwill and Other Intangibles (CenterPoint Energy and CERC)

CenterPoint Energy’s and CERC’s goodwill by reportable business segment as of both September 30, 2018 and December 31, 2017 is as follows:
 (in millions)
Natural Gas Distribution$746
Energy Services (1)110
Other Operations11
Total$867
(1) Amount presented is net of the accumulated goodwill impairment charge of $252 million recorded in 2012.

CenterPoint Energy and CERC perform goodwill impairment tests at least annually and evaluate goodwill when events or changes in circumstances indicate that its carrying value may not be recoverable. The impairment evaluation for goodwill is performed by comparing the fair value of each reporting unit with the carrying amount of the reporting unit, including goodwill. The estimated fair value of the reporting unit is primarily determined on the basis of discounted cash flows. If the carrying amount is in excess of the estimated fair value of the reporting unit, then the excess amount is the impairment charge that should be recorded, not to exceed the carrying amount of goodwill. See Note 2 for further discussion.

CenterPoint Energy and CERC performed the annual goodwill impairment test in the third quarter of 2018 and determined that no goodwill impairment charge was required for any reporting unit, which approximate the reportable segments.

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

(a) Investment in Securities Related to ZENS

In 1995, CenterPoint Energy sold a cable television subsidiary to TW and received certain TW securities as partial consideration. A subsidiary of CenterPoint Energy holds shares of certain securities detailed in the table below, 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 ZENS-Related Securities are recorded in CenterPoint Energy’s Condensed 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 as of September 30, 2018. Each ZENS was originally exchangeable at the holder’s option at any time for an amount of cash equal to 95% of the market value of the reference shares of TW Common attributable to such note. The number and identity of the reference shares attributable to each ZENS are adjusted for certain corporate events.

On October 22, 2016, AT&T announced that it had entered into a definitive agreement to acquire TW in a stock and cash transaction. On February 15, 2017, TW shareholders approved the announced transaction with AT&T. The merger closed on June 14, 2018. CenterPoint Energy received $53.75 and 1.437 shares of AT&T Common for each share of TW Common held, resulting in cash proceeds of $382 million and 10,212,945 shares of AT&T Common. In accordance with the terms of the ZENS, CenterPoint Energy remitted $382 million to ZENS note holders in July 2018, which reduced the contingent principal amount. 

On November 26, 2017, Meredith announced that it had entered into a definitive merger agreement with Time. Pursuant to the merger agreement, upon closing of the merger, a subsidiary of Meredith would purchase for cash all outstanding Time Common shares for $18.50 per share. The transaction was consummated on January 31, 2018. CenterPoint Energy elected to make a reference share offer adjustment and distribute additional interest, if any, in accordance with the terms of its ZENS rather than electing to increase the early exchange ratio to 100%. CenterPoint Energy’s distribution of additional interest in connection with the reference share offer was proportionate to the percentage of eligible shares that were validly tendered by Time stockholders in Meredith’s tender offer. CenterPoint Energy received $18.50 for each share of Time Common held, resulting in cash proceeds of approximately $16 million. In accordance with the terms of the ZENS, CenterPoint Energy distributed additional interest of approximately $16 million to ZENS holders on March 6, 2018, which reduced the contingent principal amount.

As a result, CenterPoint Energy recorded the following during the nine months ended September 30, 2018:

As of September 30, 2018, the contingent principal amount of the ZENS was $98 million.

(12) Short-term Borrowings and Long-term Debt

(a)Short-term Borrowings (CenterPoint Energy and CERC)

Inventory Financing. NGD has AMAs associated with its utility distribution service in Arkansas, Louisiana, Mississippi, Oklahoma and Texas. In March 2018, NGD’s third party AMAs in Arkansas, Louisiana and Oklahoma expired, and NGD entered into new AMAs with CES effective April 1, 2018 in these states. The AMAs have varying terms, the longest of which expires in 2021. Pursuant to the provisions of the agreements, NGD sells natural gas and agrees to repurchase an equivalent amount of natural gas during the winter heating seasons at the same cost. These transactions are accounted for as an inventory financing and had an associated principal obligation of $ -0- and $39 million as of September 30, 2018 and December 31, 2017, respectively.

(b)Long-term Debt

CenterPoint Energy Unsecured senior notes   500
 3.85% 2024
CenterPoint Energy Unsecured senior notes   500
 4.25% 2028

CenterPoint Energy intends to use the net proceeds from these debt issuances to fund a portion of the pending Merger and to pay related fees and expenses.

If CenterPoint Energy does not consummate the Merger on or prior to October 31, 2019, or if, on or prior to such date, the Merger Agreement is terminated, CenterPoint Energy will be required to redeem all of the outstanding notes at a redemption price equal to 101% of the principal amount of the notes plus accrued and unpaid interest, if any, to, but excluding, the date of such special mandatory redemption.  The notes may also be redeemed at CenterPoint Energy’s option, in whole but not in part, at any time before October 31, 2019, at a redemption price equal to 101% of the aggregate principal amount thereof plus accrued and unpaid interest thereon to, but excluding, the date of such redemption, if CenterPoint Energy determines, in its reasonable judgment, that the Merger will not be consummated on or before close of business on October 31, 2019.


Credit Facility. In May 2018, CenterPoint Energy entered into an amendment to its revolving credit facility to increase the aggregate commitments from $1.7 billion to $3.3 billion effective the earlier of (i) the termination of all commitments by certain lenders to provide the Bridge Facility and (ii) the payment in full of all obligations (other than contingent obligations) under the Bridge Facility and termination of all commitments to advance additional credit thereunder, and in each case, so long as the Merger Agreement has not been terminated pursuant to the terms thereof without consummation of the Merger. This increase to CenterPoint Energy’s revolving credit facility will automatically expire on the earlier of the (a) termination date of the revolving credit facility and (b) if the Merger Agreement is terminated without consummation of the Merger, the date that is 90 days after such termination. In addition, the amendment provides for a temporary increase on the maximum ratio of debt for borrowed money to capital from 65% to 75% until the earlier of (i) June 30, 2019 and (ii) the termination of all commitments in respect of the Bridge Facility without any borrowing thereunder. On October 5, 2018, CenterPoint Energy terminated all remaining commitments by lenders to provide the Bridge Facility. As a result, the aggregate commitments under the revolving credit facility automatically increased from $1.7 billion to $3.3 billion and the maximum ratio of debt for borrowed money to capital reverted to 65%.Houston Electric

Houston Electric wassecuritization financing, (ii) the first anniversary of CenterPoint Energy’s certification or (iii) the revocation of such certification.

The Registrants were in compliance with all financial debt covenants as of March 31,September 30, 2018.

Hedging of Interest Expense for Future Debt Issuances. In January and February 2018, Houston Electric entered into forward interest rate agreements with multiple counterparties, having an aggregate notional amount of $200 million. These agreements were executed to hedge, in part, volatility in the 30-year U.S. treasury rate by reducing Houston Electric’s exposure to variability in cash flows related to interest payments of Houston Electric’s $400 million issuance of fixed rate debt in February 2018. These forward interest rate agreements were designated as cash flow hedges. Accordingly, the effective portion of realized gains associated with the forward interest rate agreements, which totaled approximately $5 million, is a component of accumulated other comprehensive income in 2018 and will be amortized over the life of the fixed rate debt.

Other. As of both March 31,September 30, 2018 and December 31, 2017, Houston Electric had issued $118 million of general mortgage bonds as collateral for long-term debt of CenterPoint Energy. These bonds are not reflected in theHouston Electric’s consolidated financial statements because of the contingent nature of the obligations.

(1)CenterPoint Energy’s lower effective tax rate for the three and nine months ended September 30, 2018 compared to the same periods for 2017 was primarily due to the reduction in the federal corporate income tax rate from 35% to 21% effective January 1, 2018 as prescribed by the TCJA. The effective tax rate decreased by 5% and 4%, respectively, for the three and nine months ended September 30, 2018 due to the amortization of EDIT. These decreases were partially offset by an increase to the effective tax rate of 5% for the three-month period ended September 30, 2018 as a result of the establishment of a state valuation allowance on certain net operating loss deferred tax assets that are no longer expected to be utilized prior to expiration after the Internal Spin. The effective tax rate increased by 7% for the nine-month period ended September 30, 2018 due to state law changes and the state valuation allowance. See Note 9 for further discussion on the Internal Spin.

(2)Houston Electric’s lower effective tax rate for the three and nine months ended September 30, 2018 compared to the same periods for 2017 was primarily due to the reduction in the federal corporate income tax rate from 35% to 21% effective January 1, 2018 as prescribed by the TCJA. The effective tax rate was further reduced by 2% for both periods due to the amortization of EDIT.

(3)CERC’s lower effective tax rate on the loss from continuing operations for the three months ended September 30, 2018 compared to the same period in 2017 was primarily due to the reduction in the federal corporate income tax rate from 35% to 21% effective January 1, 2018 as prescribed by the TCJA. The effective tax rate decreased by 18% due to state taxes as a result of the establishment of a state valuation allowance on certain net operating loss deferred tax assets that are no longer expected to be utilized prior to expiration after the Internal Spin. These decreases were partially offset by an increase to the effective tax rate of 15% due to the amortization of EDIT. See Note 9 for further discussion on the Internal Spin.

(4)CERC’s lower effective tax rate on income from continuing operations for the nine months ended September 30, 2018 compared to the same period in 2017 was primarily due to the reduction in the federal corporate income tax rate from 35% to 21% effective January 1, 2018 as prescribed by the TCJA. The effective tax rate decreased by 20% due to the amortization of EDIT. These decreases were partially offset by an increase to the effective tax rate of 22% as a result of an increase in state tax rates and the establishment of a state valuation allowance on certain net operating loss deferred tax assets that are no longer expected to be utilized prior to expiration after the Internal Spin. See Note 9 for further discussion on the Internal Spin.

(5)CERC’s lower effective tax rate on income from discontinued operations for the three and nine months ended September 30, 2018 compared to the same periods in 2017 was primarily due to the reduction in the federal corporate income tax rate from 35% to 21% effective January 1, 2018 as prescribed by the TCJA. See Note 9 for further discussion on the Internal Spin and the associated discontinued operations presentation.

The Registrants reported no uncertain tax liability as of September 30, 2018 and expect no significant changes to the uncertain tax liability over the next twelve months. Tax years through 2016 have been audited and settled with the IRS, however, during the

three months ended September 30, 2018, CenterPoint Energy filed an amended 2014 tax return to claim additional tax credits that is currently under review by the IRS. For the 2017 and 2018 tax years, CenterPoint Energy is a participant in the IRS’s Compliance Assurance Process.

(14) Commitments and Contingencies

(a)Natural Gas Supply Commitments (CenterPoint Energy and CERC)

Natural gas supply commitments include natural gas contracts related to CenterPoint Energy’s and CERC’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 and CERC’s Condensed Consolidated Balance Sheets as of September 30, 2018 and December 31, 2017 as these contracts meet an exception as “normal purchases contracts” or do not meet the definition of a derivative. Natural gas supply commitments also include natural gas transportation contracts that do not meet the definition of a derivative.

As of September 30, 2018, minimum payment obligations for natural gas supply commitments are approximately:

(b)Legal, Environmental and Other Matters

Legal Matters

Gas Market Manipulation Cases (CenterPoint Energy and CERC).  CenterPoint Energy, Houston Electric or theirits predecessor, Reliant Energy, and certain of their former subsidiaries have beenwere named as defendants in certaina large number of lawsuits described below. filed against numerous gas market participants in a number of federal and western state courts in connection with the operation of the natural gas markets in 2000-2002. CenterPoint Energy and its affiliates were released or dismissed from all such cases, except for one case pending in federal court in Nevada in which CES, a subsidiary of CERC Corp., is a defendant. Plaintiffs in that case allege a conspiracy to inflate Wisconsin natural gas prices in 2000-2002. In May 2016, the district court granted CES’s motion for summary judgment, dismissing CES from the case. In August 2018, the Ninth Circuit Court of Appeals reversed that ruling, and CES requested further appellate review of that decision.

Under a master separation agreement between CenterPoint Energy and a former subsidiary, RRI, CenterPoint Energy and its subsidiaries are entitled to be indemnified by RRI and its successors for any losses, including certain attorneys’ fees and other costs, arising out of these lawsuits.  In May 2009,Through a series of transactions, RRI sold its Texas retail business to a subsidiary of NRGbecame known as GenOn and RRI changed its name to RRI Energy, Inc. In December 2010, Mirant Corporation merged with and became a wholly-owned subsidiary of RRI, and RRI changed its name to GenOn. In December 2012, NRG acquired GenOn through a merger in which GenOn became a wholly-owned subsidiary of NRG. None of the sale of the retail business, the merger with Mirant Corporation, or the acquisition of GenOn by NRGthose transactions alters RRI’s (now GenOn’s)GenOn’s contractual obligations to indemnify CenterPoint Energy and its subsidiaries including Houston Electric, for certain liabilities, including their indemnification obligations regarding the gas market manipulation litigation.

A large number of lawsuits were filed against numerous gas market participants in a number of federal and western state courts in connection with the operation of the natural gas markets in 2000–2002. CenterPoint Energy and its affiliates have since been released or dismissed from all such cases. CES, a subsidiary of CERC Corp., was a defendant in a case now pending in federal court in Nevada alleging a conspiracy to inflate Wisconsin natural gas prices in 2000–2002.  On May 24, 2016, the district court granted CES’s motion for summary judgment, dismissing CES from the case. The plaintiffs have appealed that ruling. CenterPoint Energy and CES intend to continue vigorously defending against the plaintiffs’ claims. In June 2017, however, GenOn and various affiliates filed for protection under Chapter 11 of the U.S. Bankruptcy Code. In December 2017, GenOn received court approval of a restructuring planCode and isare expected to emerge from Chapter 11 in mid-2018.2018. CenterPoint Energy, CERC, and CES submitted proofs of claim in the bankruptcy proceedings to protect their indemnity rights.

In October 2018, CES, GenOn, and the plaintiffs reached an agreement to settle all claims against CES and CES’s indemnity claims against GenOn, subject to approvals by the bankruptcy court and the federal district court. If GenOn were unablethe settlement agreement is not approved and if GenOn’s bankruptcy proceedings result in it not being required to meetfulfill its indemnity obligations, or satisfy a liability that has been assumed in the gas market manipulation litigation, then Houston Electric, CenterPoint Energy or CERCCES could incur liability and be responsible for satisfying the liability. Houston Electricit. CenterPoint Energy does not expect the ultimate outcome of the case against CESthis matter to have a material adverse effect on its financial condition, results of operations or cash flows.

Minnehaha Academy (CenterPoint Energy and CERC).  On August 2, 2017, a natural gas explosion occurred at the Minnehaha Academy in Minneapolis, Minnesota, resulting in the deaths of two school employees, serious injuries to others and significant property damage to the school.  CenterPoint Energy, certain of its subsidiaries, including CERC, and the contractor company working in the school have been named in litigation arising out of this incident.  CenterPoint Energy has reached confidential settlement agreements with some claimants. Additionally, CenterPoint Energy is cooperating with the ongoing investigation conducted by the National Transportation Safety Board. Further, CenterPoint Energy is contesting approximately $200,000 in

fines imposed by the Minnesota Office of Pipeline Safety.  In early 2018, the Minnesota Occupational Safety and Health Administration concluded its investigation without any adverse findings against CenterPoint Energy. CenterPoint Energy’s general and excess liability insurance policies provide coverage for third party bodily injury and property damage claims. 

Environmental Matters

Asbestos.MGP Sites (CenterPoint Energy and CERC). CERC and its predecessors operated MGPs in the past.  With respect to certain Minnesota MGP sites, CERC has completed state-ordered remediation and continues state-ordered monitoring and water treatment. As of September 30, 2018, CERC had a recorded liability of $7 million for continued monitoring and any future remediation required by regulators in Minnesota. The estimated range of possible remediation costs for the sites for which CERC believes it may have responsibility was $4 million to $30 million based on remediation continuing for 30 to 50 years. The cost estimates are based on studies of a site or industry average costs for remediation of sites of similar size. The actual remediation costs will depend on the number of sites to be remediated, the participation of other PRPs, if any, and the remediation methods used. 

In addition to the Minnesota sites, the EPA and other regulators have investigated MGP sites that were owned or operated by CERC or may have been owned by one of its former affiliates. CenterPoint Energy and CERC do not expect the ultimate outcome of these matters to have a material adverse effect on the financial condition, results of operations or cash flows of either CenterPoint Energy or CERC.

Asbestos.Some facilities owned by Houston Electricthe Registrants or their predecessors in interest contain or have contained asbestos insulation and other asbestos-containing materials. CenterPoint Energy and its subsidiaries, including Houston Electric,The Registrants are from time to time named, along with numerous others, as defendants in lawsuits filed by a number of individuals who claim injury due to exposure to asbestos, and CenterPoint Energy anticipatesthe Registrants anticipate that additional claims may be asserted in the future.  Although their ultimate outcome cannot be predicted at this

time, Houston Electric doesthe Registrants do not expect these matters, either individually or in the aggregate, to have a material adverse effect on Houston Electric’stheir financial condition, results of operations or cash flows.

Other Environmental.From time to time, Houston Electric identifiesthe Registrants identify the presence of environmental contaminants during its operations or on property where its predecessor companies have conducted operations.  Other such sites involving contaminants may be identified in the future.  Houston Electric hasThe Registrants have and expectsexpect to continue to remediate any identified sites consistent with its state and federal legal obligations.  From time to time, Houston Electric hasthe Registrants have received notices, and may receive notices in the future, 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, Houston Electric hasthe Registrants have been, or may be, named from time to time as a defendantdefendants in litigation related to such sites. Although the ultimate outcome of such matters cannot be predicted at this time, Houston Electric doesthe Registrants do not expect these matters, either individually or in the aggregate, to have a material adverse effect on itstheir financial condition, results of operations or cash flows.

(11)(16) Reportable Business Segments

The Registrants’ determination of reportable business segments considers the strategic operating units under which the Registrants manage sales, allocate resources and assess performance of various products and services to wholesale or retail customers in differing regulatory environments. The Registrants use operating income as the measure of profit or loss for the business segments other than Midstream Investments, where equity in earnings is used.

As of September 30, 2018, reportable business segments by Registrant are as follows:
Electric Transmission & DistributionNatural Gas Distribution
Energy
 Services
Midstream InvestmentsOther Operations
CenterPoint EnergyXXXXX
Houston ElectricX
CERCXX(1)X

(1)In the three months ended September 30, 2018, CERC completed the Internal Spin. Previously, CERC’s equity method investment in Enable was included in the Midstream Investments segment. CERC’s equity in earnings in Enable, net of basis difference amortization and income tax, has been classified as discontinued operations for all periods presented. See Note 9 for further discussion on the Internal Spin and the associated discontinued operations presentation.

Electric Transmission & Distribution consists of the electric transmission and distribution function. 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 consists of non-rate regulated natural gas sales and services operations. Midstream Investments consists of the equity investment in Enable (excluding the Enable Series A Preferred Units). Other Operations consists primarily of other corporate operations which support all of the business operations.

Houston Electric consists of a single reportable business segment and therefore is not included in the tabular business segment presentation below. Operating income (loss) amounts for 2017 have been recast to reflect the adoption of ASU 2017-07 (see Note 2 for further information).

Series A Preferred Stock

On August 22, 2018, CenterPoint Energy completed the issuance of 800,000 shares of its Series A Preferred Stock, at a price of $1,000 per share, resulting in net proceeds of $790 million after issuance costs. The aggregate liquidation value of the Series A Preferred Stock is $800 million with a per share liquidation value of $1,000.

CenterPoint Energy intends to use the net proceeds from the Series A Preferred Stock offering to fund a portion of the pending Merger and to pay related fees and expenses.

Dividends. S NARRATIVE ANALYSIS OF RESULTS OF OPERATIONSThe Series A Preferred Stock accrue cumulative dividends, calculated as a percentage of the stated amount per share, at a fixed annual rate of 6.125% per annum to, but excluding, September 1, 2023, and at an annual rate of three-month LIBOR plus a spread of 3.270% thereafter to be paid in cash if, when and as declared. If declared, prior to September 1, 2023, dividends are payable semi-annually in arrears on each March 1 and September 1, beginning on March 1, 2019, and, for the period commencing on September 1, 2023, dividends are payable quarterly in arrears each March 1, June 1, September 1 and December 1, beginning on December 1, 2023. Cumulative dividends accrued during the applicable periods are presented on CenterPoint Energy’s Condensed Statements of Consolidated Income as Series A Preferred Stock dividend requirement.

Optional Redemption. On or after September 1, 2023, CenterPoint Energy may, at its option, redeem the Series A Preferred Stock, in whole or in part, at any time or from time to time, for cash at a redemption price of $1,000 per share, plus any accumulated and unpaid dividends thereon to, but excluding, the redemption date.

At any time within 120 days after the conclusion of any review or appeal process instituted by CenterPoint Energy, if any, following the occurrence of a ratings event, CenterPoint Energy may, at its option, redeem the Series A Preferred Stock in whole, but not in part, at a redemption price in cash per share equal to $1,020 (102% of the liquidation value of $1,000) plus an amount equal to all accumulated and unpaid dividends thereon to, but excluding, the redemption date, whether or not declared.

Ranking. The Series A Preferred Stock, with respect to anticipated dividends and distributions upon CenterPoint Energy’s liquidation or dissolution, or winding-up of CenterPoint Energy’s affairs, ranks or will rank:

senior to Common Stock and to each other class or series of capital stock established after the initial issue date of the Series A Preferred Stock that is expressly made subordinated to the Series A Preferred Stock;

on a parity with any class or series of capital stock established after the initial issue date of the Series A Preferred Stock that is not expressly made senior or subordinated to the Series A Preferred Stock, including the Series B Preferred Stock;

junior to any class or series of capital stock established after the initial issue date of the Series A Preferred Stock that is expressly made senior to the Series A Preferred Stock;

junior to all existing and future indebtedness (including indebtedness outstanding under CenterPoint Energy’s credit facilities, senior notes and commercial paper) and other liabilities with respect to assets available to satisfy claims against CenterPoint Energy; and

structurally subordinated to any existing and future indebtedness and other liabilities of CenterPoint Energy’s subsidiaries and capital stock of CenterPoint Energy’s subsidiaries held by third parties.

Voting Rights. Holders of the Series A Preferred Stock generally will not have voting rights. Whenever dividends on shares of Series A Preferred Stock have not been declared and paid for the equivalent of three or more semi-annual or six or more quarterly dividend periods (including, for the avoidance of doubt, the dividend period beginning on, and including, the original issue date and ending on, but excluding, March 1, 2019), whether or not consecutive, the holders of such shares of Series A Preferred Stock, voting together as a single class with holders of any and all other series of voting preferred stock (as defined in the Statement of Resolution for the Series A Preferred Stock) then outstanding, will be entitled at CenterPoint Energy’s next annual or special meeting of shareholders to vote for the election of a total of two additional members of CenterPoint Energy’s Board of Directors, subject to certain limitations. This right will terminate if and when all accumulated dividends have been paid in full and, upon such termination, the term of office of each director so elected will terminate at such time and the number of directors on CenterPoint Energy’s Board of Directors will automatically decrease by two, subject to the revesting of such rights in the event of each subsequent nonpayment.


Series B Preferred Stock

On October 1, 2018, CenterPoint Energy completed the issuance of 19,550,000 depositary shares, each representing a 1/20th interest in a share of its Series B Preferred Stock, at a price of $50 per depositary share, resulting in net proceeds of $950 million after issuance costs. The aggregate liquidation value of Series B Preferred Stock is $978 million with a per share liquidation value of $1,000. The amount issued included 2,550,000 depositary shares issued pursuant to the exercise in full of the option granted to the underwriters to purchase additional depositary shares.

CenterPoint Energy intends to use the net proceeds from the offering of depositary shares, each representing a 1/20th interest in a share of Series B Preferred Stock, to fund a portion of the pending Merger and to pay related fees and expenses.

Dividends. Dividends on the Series B Preferred Stock will be payable on a cumulative basis when, as and if declared at an annual rate of 7.00% on the liquidation value of $1,000 per share. CenterPoint Energy may pay declared dividends in cash or, subject to certain limitations, in shares of Common Stock, or in any combination of cash and shares of Common Stock on March 1, June 1, September 1 and December 1 of each year, commencing on December 1, 2018 and ending on, and including, September 1, 2021.

Acquisition Termination Redemption. If the pending Merger has not closed at or prior to close of business on April 21, 2019 or if an acquisition termination event occurs, CenterPoint Energy may, at its option, give notice of an acquisition termination redemption to the holders of the Series B Preferred Stock. If CenterPoint Energy provides such notice, then, on the acquisition termination redemption date, CenterPoint Energy will be required to redeem the Series B Preferred Stock, in whole but not in part, at a redemption amount per share of the Series B Preferred Stock equal to the acquisition termination redemption amount. CenterPoint Energy will pay the acquisition termination redemption amount in cash unless the acquisition termination share price is greater than the initial price, in which case CenterPoint Energy will instead pay the acquisition termination redemption amount by delivering shares of Common Stock and cash; provided, that CenterPoint Energy may elect, subject to certain limitations, to pay cash or deliver shares of Common Stock in lieu of these amounts. If CenterPoint Energy redeems shares of the Series B Preferred Stock held by the depositary, the depositary will redeem, on the same acquisition termination redemption date, the number of the depositary shares representing the shares of the Series B Preferred Stock so redeemed.

Mandatory Conversion. Unless earlier converted or redeemed, each share of the Series B Preferred Stock will automatically convert on the mandatory conversion date, which is expected to be September 1, 2021, into not less than 30.5820 and not more than 36.6980 shares of Common Stock, subject to certain anti-dilution adjustments. Correspondingly, the conversion rate per depositary share will be not less than 1.5291 and not more than 1.8349 shares of Common Stock, subject to certain anti-dilution adjustments. The conversion rate will be determined based on a preceding 20-day volume-weighted-average-price of Common Stock.

The following narrativetable illustrates the conversion rate per share of the Series B Preferred Stock, subject to certain anti-dilution adjustments:
Applicable Market Value of the Common StockConversion Rate per Share of Series B Preferred Stock
Greater than $32.6990 (threshold appreciation price)30.5820 shares of Common Stock
Equal to or less than $32.6990 but greater than or equal to $27.2494Between 30.5820 and 36.6980 shares of Common Stock, determined by dividing $1,000 by the applicable market value
Less than $27.2494 (initial price)36.6980 shares of Common Stock

The following table illustrates the conversion rate per depositary share, subject to certain anti-dilution adjustments:
Applicable Market Value of the Common StockConversion Rate per Depository Share
Greater than $32.6990 (threshold appreciation price)1.5291 shares of Common Stock
Equal to or less than $32.6990 but greater than or equal to $27.2494Between 1.5291 and 1.8349 shares of Common Stock, determined by dividing $50 by the applicable market value
Less than $27.2494 (initial price)1.8349 shares of Common Stock

Optional Conversion of the Holder. Other than during a fundamental change conversion period, and unless CenterPoint Energy has redeemed the Series B Preferred Stock, a holder of the Series B Preferred Stock may, at any time prior to September 1, 2021, elect to convert such holder’s shares of the Series B Preferred Stock, in whole or in part, at the minimum conversion rate of 30.5820 shares of Common Stock per share of the Series B Preferred Stock (equivalent to 1.5291 shares of Common Stock per depositary share), subject to certain anti-dilution and other adjustments. Because each depositary share represents a 1/20th fractional interest

in a share of the Series B Preferred Stock, a holder of depositary shares may convert its depositary shares only in lots of 20 depositary shares.

Fundamental Change Conversion. If a fundamental change occurs on or prior to September 1, 2021, holders of the Series B Preferred Stock will have the right to convert their shares of the Series B Preferred Stock, in whole or in part, into shares of Common Stock at the fundamental change conversion rate during the period beginning on, and including, the effective date of such fundamental change and ending on, and including, the date that is 20 calendar days after such effective date (or, if later, the date that is 20 calendar days after holders receive notice of such fundamental change, but in no event later than September 1, 2021). Holders who convert shares of the Series B Preferred Stock during that period will also receive a make-whole dividend amount comprised of a fundamental change dividend make-whole amount, and to the extent there is any, the accumulated dividend amount. Because each depositary share represents a 1/20th fractional interest in a share of the Series B Preferred Stock, a holder of depositary shares may convert its depositary shares upon a fundamental change only in lots of 20 depositary shares.

Ranking. The Series B Preferred Stock, with respect to anticipated dividends and distributions upon CenterPoint Energy’s liquidation or dissolution, or winding-up of CenterPoint Energy’s affairs, ranks or will rank:

senior to Common Stock and to each other class or series of capital stock established after the initial issue date of the Series B Preferred Stock that is expressly made subordinated to the Series B Preferred Stock;

on a parity with the Series A Preferred Stock and any class or series of capital stock established after the initial issue date that is not expressly made senior or subordinated to the Series B Preferred Stock;

junior to any class or series of capital stock established after the initial issue date that is expressly made senior to the Series B Preferred Stock;

junior to all existing and future indebtedness (including indebtedness outstanding under CenterPoint Energy’s credit facilities, senior notes and commercial paper) and other liabilities with respect to assets available to satisfy claims against CenterPoint Energy; and

structurally subordinated to any existing and future indebtedness and other liabilities of CenterPoint Energy’s subsidiaries and capital stock of CenterPoint Energy’s subsidiaries held by third parties.

Voting Rights. Holders of the Series B Preferred Stock generally will not have voting rights. Whenever dividends on shares of the Series B Preferred Stock have not been declared and paid for six or more dividend periods (including, for the avoidance of doubt, the dividend period beginning on, and including, the initial issue date and ending on, but excluding, December 1, 2018), whether or not consecutive, the holders of such shares of Series B Preferred Stock, voting together as a single class with holders of any and all other series of voting preferred stock then outstanding (as defined in the Statement of Resolution for the Series B Preferred Stock), will be entitled at CenterPoint Energy’s next annual or special meeting of shareholders to vote for the election of a total of two additional members of CenterPoint Energy’s Board of Directors, subject to certain limitations. This right will terminate if and when all accumulated and unpaid dividends have been paid in full and, upon such termination, the term of office of each director so elected will terminate at such time and the number of directors on CenterPoint Energy’s Board of Directors will automatically decrease by two, subject to the revesting of such rights in the event of each subsequent nonpayment.

Three months ended September 30, 2018 compared to three months ended September 30, 2017

We reported income available to common shareholders of $153 million ($0.35 per diluted share) for the three months ended September 30, 2018 compared to $169 million ($0.39 per diluted share) for the same period in 2017.

The decrease of $16 million in income available to common shareholders was primarily due to the following key factors:

a $71 million decrease in operating income discussed below by segment in Results of Operations by Business Segment;

a $10 million increase in interest expense primarily due to the amortization of Bridge Facility fees;

an $8 million increase in losses on the underlying value of the indexed debt securities related to the ZENS included in Other Income (Expense), net shown above; and

a $5 million increase in preferred dividend requirements on our Series A Preferred Stock.

These decreases in income available to common shareholders were partially offset by the following:

a $47 million decrease in income tax expense due to lower net income and a reduction in the corporate income tax rate resulting from the TCJA;

a $13 million increase in equity earnings from our investment in Enable, discussed further in Note 9 to the Interim Condensed Financial Statements;

a $9 million decrease in non-service cost components of net periodic pension and post-retirement costs included in Other Income (Expense), net shown above;

a $6 million increase in gains on marketable securities included in Other Income (Expense), net shown above;

a $2 million decrease in interest expense related to lower outstanding balances of our Securitization Bonds; and

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

Nine months ended September 30, 2018 compared to nine months ended September 30, 2017

We reported income available to common shareholders of $243 million ($0.56 per diluted share) for the nine months ended September 30, 2018 compared to $496 million ($1.14 per diluted share) for the nine months ended September 30, 2017.

The decrease of $253 million in income available to common shareholders was primarily due to the following key factors:

a $257 million increase in losses on indexed debt securities related to the ZENS included in Other Income (Expense), net shown above, resulting from a loss of $11 million from Meredith’s acquisition of Time in March 2018, a loss of $242 million from AT&T’s acquisition of TW in June 2018 and increased losses of $4 million in the underlying value of the indexed debt securities;

a $164 million decrease in operating income discussed below by segment in Results of Operations by Business Segment;

a $38 million decrease in gains on marketable securities included in Other Income (Expense), net shown above;

a $24 million increase in interest expense due to higher outstanding other long-term debt and the amortization of Bridge Facility fees of $17 million; and

a $5 million increase in preferred dividend requirements on our Series A Preferred Stock.

These decreases in income available to common shareholders were partially offset by the following:

a $196 million decrease in income tax expense due to lower net income and a reduction in the corporate income tax rate resulting from the TCJA;

a $14 million decrease in non-service cost components of net periodic pension and post-retirement costs included in Other Income (Expense), net shown above;

a $12 million decrease in interest expense related to lower outstanding balances of our Securitization Bonds;

a $9 million increase in equity earnings from our investment in Enable, discussed further in Note 9 to the Interim Condensed Financial Statements; and

a $4 million increase in miscellaneous other non-operating income included in Other Income (Expense), net shown above.

Income Tax Expense

Our effective tax rate reported for the three months ended September 30, 2018 was 24% compared to 37% for the same period in 2017. The effective tax rate reported for the nine months ended September 30, 2018 was 26% compared to 36% for the same period in 2017. The lower effective tax rates for the three and nine months ended September 30, 2018 were primarily due to the reduction in the federal corporate income tax rate from 35% to 21% effective January 1, 2018 as prescribed by the TCJA. The effective tax rate also decreased by 5% and 4%, respectively, for the three and nine months ended September 30, 2018 due to the amortization of EDIT. These decreases were partially offset by an increase to the effective tax rate of 5% for the three-month period ended September 30, 2018 as a result of the establishment of a state valuation allowance on certain net operating loss deferred tax assets that are no longer expected to be utilized prior to expiration after the Internal Spin. The effective tax rate was increased by 7% for the nine-month period ended September 30, 2018 due to state law changes and the state valuation allowance. See Note 9 to the Interim Condensed Financial Statements for further discussion on the Internal Spin. We expect our annual effective tax rate for the fiscal year ending December 31, 2018 to be approximately 24%.

Three months ended March 31,September 30, 2018 compared to three months ended March 31,September 30, 2017

Houston Electric reported net income of $143 million for the three months ended September 30, 2018 compared to net income of $130 million for the same period in 2017.  

The increase of $13 million in net income was primarily due to a $35 million decrease in income tax expense due to lower net income and a reduction in the corporate income tax rate resulting from the TCJA.

This increase in net income was partially offset by a $22 million decrease in TDU operating income as discussed below in Results of Operations by Business Segment.

Nine months ended September 30, 2018 compared to nine months ended September 30, 2017

Houston Electric reported net income of $296 million for the nine months ended September 30, 2018 compared to net income of $223 million for the nine months ended September 30, 2017.  

The increase of $73 million in net income was primarily due to the following key factors:

a $45 million decrease in income tax expense due to lower net income and a reduction in the corporate income tax rate resulting from the TCJA; and

a $32 million increase in TDU operating income resulting from a $27 million increase discussed below in Results of Operations by Business Segment and increased usage of $5 million, primarily due to a return to more normal weather, which was not offset by the weather hedge loss recorded on CenterPoint Energy.

These increases in net income were partially offset by a $4 million increase in interest expense due to higher outstanding other long-term debt.

Income Tax Expense

Houston Electric’s effective tax rate reported for the three months ended September 30, 2018 was 20% compared to 35% for the same period in 2017. The effective tax rate reported for the nine months ended September 30, 2018 was 21% compared to 36% for the same period in 2017. The lower effective tax rate for the three and nine months ended September 30, 2018 was primarily

due to the reduction in the federal corporate income tax rate from 35% to 21% effective January 1, 2018 as prescribed by the TCJA. The effective tax rate also decreased by 2% for both periods due to the amortization of EDIT.

CERC’S MANAGEMENT’S NARRATIVE ANALYSIS OF CONSOLIDATED RESULTS OF OPERATIONS

CERC’s results of operations are affected by seasonal fluctuations in the demand for natural gas and price movements of energy commodities as well as natural gas basis differentials. CERC’s results of operations are also affected by, among other things, the actions of various federal, state and local governmental authorities having jurisdiction over rates CERC charges, competition in CERC’s various business operations, the effectiveness of CERC’s risk management activities, debt service costs and income tax expense. For more information regarding factors that may affect the future results of operations for CERC’s business, please read “Risk Factors” in Item 1A of Part I of CERC’s 2017 Form 10-K.

Three months ended September 30, 2018 compared to three months ended September 30, 2017

CERC reported net income of $9 million for the three months ended September 30, 2018 compared to net income of $38 million for the same period in 2017.  

The decrease of $29 million in net income was primarily due to a $38 million decrease in operating income discussed below by segment in Results of Operations by Business Segment.

The decrease to net income was partially offset by the following:

a $4 million increase in miscellaneous other non-operating income included in Other expense, net shown above, primarily due to lower non-service cost components of net periodic postretirement costs;

a $2 million decrease in interest expense due to lower outstanding long-term debt;

a $2 million increase in income from discontinued operations, net of tax, discussed further in Notes 9 and 13 to the Interim Condensed Financial Statements; and

a $1 million decrease in income tax expense due to lower income from continuing operations and a reduction in the corporate income tax rate resulting from the TCJA, partially offset by an increase in the state tax valuation allowance.

Nine months ended September 30, 2018 compared to nine months ended September 30, 2017

CERC reported net income of $175 million for the nine months ended September 30, 2018 compared to net income of $239 million for the nine months ended September 30, 2017.  

The decrease of $64 million in net income was primarily due to a $143 million decrease in operating income discussed below by segment in Results of Operations by Business Segment.


The decrease to net income was partially offset by the following:

a $55 million decrease in income tax expense due to lower income from continuing operations and a reduction in the corporate income tax rate resulting from the TCJA, partially offset by an increase in the state tax valuation allowance;

a $16 million increase in income from discontinued operations, net of tax, discussed further in Notes 9 and 13 to the Interim Condensed Financial Statements; and

an $8 million increase in miscellaneous other non-operating income included in Other expense, net shown above, primarily due to lower non-service cost components of net periodic postretirement costs.

Income Tax Expense - Continuing Operations

CERC’s effective tax rate on the loss from continuing operations for the three months ended September 30, 2018 was 5% compared to 20% for the same period in 2017. The lower effective tax rate on the loss from continuing operations for the three months ended September 30, 2018 compared to the same period in 2017 was primarily due to the reduction in the federal corporate income tax rate from 35% to 21% effective January 1, 2018 as prescribed by the TCJA. The effective tax rate decreased by 18% due to state taxes as a result of the establishment of a state valuation allowance on certain net operating loss deferred tax assets that are no longer expected to be utilized prior to expiration after the Internal Spin. These decreases were partially offset by an increase to the effective tax rate of 15% due to the amortization of EDIT. See Note 9 to the Interim Condensed Financial Statements for further discussion on the Internal Spin.

CERC’s effective tax rate reported on income from continuing operations for the nine months ended September 30, 2018 was 29% compared to 38% for the same period in 2017. The lower effective tax rate on income from continuing operations for the nine months ended September 30, 2018 compared to the same period in 2017 was primarily due to the reduction in the federal corporate income tax rate from 35% to 21% effective January 1, 2018 as prescribed by the TCJA. The effective tax rate also decreased by 20% due to the amortization of EDIT. These decreases were partially offset by an increase to the effective tax rate of 22% as a result of an increase in state tax rates and the establishment of a state valuation allowance on certain net operating loss deferred tax assets that are no longer expected to be utilized prior to expiration after the Internal Spin. See Note 9 to the Interim Condensed Financial Statements for further discussion on the Internal Spin.

WeThree months ended September 30, 2018 compared to three months ended September 30, 2017

Our Electric Transmission & Distribution business segment reported operating income of $119$227 million for the three months ended March 31,September 30, 2018, consisting of $103$214 million from the TDU and $16$13 million related to the Bond Companies. For the three months ended March 31,September 30, 2017, operating income totaled $85$254 million, consisting of $65$236 million from the TDU and $20$18 million related to the Bond Companies.

TDU operating income increased $38decreased $22 million, primarily due to the following key factors:

higher equity return of $14 million, primarily related to the annual true-up of transition charges correcting for under-collections that occurred during the preceding 12 months;

higher usage of $13 million, primarily due to a return to more normal weather;

rate increases of $9 million related to distribution capital investments;


higher transmission-related revenues of $8 millionincreased operation and lowermaintenance expenses, excluding transmission costs billed by transmission providers, of $6 million; and$38 million primarily due to the following:

customer growth of $6 million from the addition of almost 40,000 customers.
contract services of $10 million, largely due to increased vegetation management and preventative maintenance resiliency spend;

support services of $9 million, primarily related to technology projects;
These increases to operating income were partially offset by the following:
other miscellaneous operation and maintenance expenses of $9 million;

labor and benefits costs of $6 million; and

damage claims from third parties of $4 million;

lower revenues of $12$22 million due to the recording of a regulatory liability and a corresponding decrease to revenue of $6 million reflecting the difference in revenues collected under existing customer rates and the revenues that would have been collected had existing rates been set using the lower corporate tax rate from the TCJA and lower revenues of $16 million due to lower transmission and distribution rate filings as a result of the TCJA; and

higher depreciation and amortization expense, primarily because of ongoing additions to plant in service, and other taxes of $5 million.

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

higher transmission-related revenues of $14 million, exclusive of the TCJA impact discussed above, and lower transmission costs billed by transmission providers of $8 million;

customer growth of $9 million from the addition of over 39,000 customers;

rate increases of $8 million related to distribution capital investments, exclusive of the TCJA impact discussed above; and

higher equity return of $4 million, primarily related to the annual true-up of transition charges correcting for under-collections that occurred during the preceding 12 months.

Lower depreciation and amortization expenses related to AMS of $7 million were offset by a corresponding decrease in related revenues.

Nine months ended September 30, 2018 compared to nine months ended September 30, 2017

Our Electric Transmission & Distribution business segment reported operating income of $523 million for the nine months ended September 30, 2018, consisting of $480 million from the TDU and $43 million related to the Bond Companies. For the nine months ended September 30, 2017, operating income totaled $511 million, consisting of $453 million from the TDU and $58 million related to the Bond Companies.

TDU operating income increased $27 million, primarily due to the following key factors:

higher equity return of $33 million, primarily related to the annual true-up of transition charges correcting for under-collections that occurred during the preceding 12 months;

rate increases of $29 million related to distribution capital investments, exclusive of the TCJA impact discussed below;

higher transmission-related revenues of $28 million, exclusive of the TCJA impact discussed below, and lower transmission costs billed by transmission providers of $22 million;

customer growth of $23 million from the addition of over 39,000 customers;

higher usage of $12 million, primarily due to a return to more normal weather; and

increased miscellaneous revenues, including right-of-way, of $5 million.

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

increased operation and maintenance expenses, excluding transmission costs billed by transmission providers, of $60 million primarily due to the following:

support services of $17 million, primarily related to technology projects;


other miscellaneous operation and maintenance expenses of $14 million;

contract services of $15 million, largely due to increase in vegetation management and preventative maintenance resiliency spend;

labor and benefits costs of $10 million; and

damage claims from third parties of $4 million;

lower revenues of $53 million due to the recording of a regulatory liability and a corresponding decrease to revenue of $30 million reflecting the difference in revenues collected under existing customer rates and the revenues that would have been collected had existing rates been set using the lower corporate tax rate from the TCJA and lower revenues of $23 million due to lower transmission and distribution rate filings as a result of the TCJA; and

higher depreciation and amortization expense, primarily because of ongoing additions to plant in service, and other taxes of $11 million.

Lower depreciation and amortization expenses related to AMS of $11 million were offset by a corresponding decrease in related revenues.

Three months ended September 30, 2018 compared to three months ended September 30, 2017

Our Natural Gas Distribution business segment reported operating income of $3 million for the three months ended September 30, 2018 compared to $25 million for the three months ended September 30, 2017.


Operating income decreased $22 million primarily as a result of the following key factors:

higher operation and maintenance expenses of $25 million, primarily consisting of:

support services expense of $7 million, primarily related to technology projects;

contracts and services, materials and supplies and damage claims from third parties of $6 million;

labor and benefits costs of $6 million; and

other miscellaneous operation and maintenance expenses of $6 million;

increased depreciation and amortization expenses of $7 million, due to ongoing additions to plant-in-service; and

lower revenue of $6 million related to the lower corporate tax rate from the TCJA.

These decreases were partially offset by the following:

a $6 million increase from weather and usage, driven by the timing of the decoupling mechanism in Minnesota;

a $5 million increase in rate relief, primarily in the Texas, Arkansas, Mississippi and Minnesota jurisdictions, exclusive of the TCJA impact discussed above; and

a $2 million increase associated with customer growth from the addition of almost 29,000 customers.

Increased operation and maintenance expenses related to energy efficiency programs of $1 million and increased gross receipts taxes of $1 million were offset by corresponding increases in the related revenues.

Nine months ended September 30, 2018 compared to nine months ended September 30, 2017

Our Natural Gas Distribution business segment reported operating income of $166 million for the nine months ended September 30, 2018 compared to $235 million for the nine months ended September 30, 2017.

Operating income decreased $69 million as a result of the following key factors:

higher operation and maintenance expenses of $35 million, primarily consisting of:

contracts and services, materials and supplies, bad debt and damage claims from third parties of $19 million;

support services expenses of $12 million, primarily related to technology projects; and

other miscellaneous operation and maintenance expenses of $10 million;

which decreases were partially offset by a timing-related adjustment associated with the Texas Gulf rate order of $6 million;

higher labor and benefits costs of $28 million, resulting primarily from the recording of regulatory assets (and a corresponding reduction in expense) to recover $16 million of prior post-retirement expenses in future rates established in the Texas Gulf rate order in 2017;

lower revenue of $26 million, associated with the recording of a regulatory liability and a corresponding decrease to revenue in certain jurisdictions of $15 million reflecting the difference in revenues collected under existing customer rates and the revenues that would have been collected had existing rates been set using the lower corporate tax rate from the TCJA and lower filing amounts in Minnesota and south Texas of $11 million associated with the lower corporate tax rate as a result of the TCJA;

increased depreciation and amortization expense of $16 million, primarily due to ongoing additions to plant-in-service; and

higher other taxes of $9 million, primarily due to the 2017 Minnesota property tax refund.

These decreases were partially offset by the following:

rate increases of $35 million, primarily in the Texas, Minnesota and Arkansas jurisdictions, exclusive of the TCJA impact discussed above;

an increase in non-volumetric revenues of $8 million; and

a $6 million increase associated with customer growth from the addition of almost 29,000 customers.

Increased operation and maintenance expenses related to energy efficiency programs of $13 million and increased gross receipts taxes of $6 million were offset by corresponding increases in the related revenues.

Three months ended September 30, 2018 compared to three months ended September 30, 2017

Our Energy Services business segment reported an operating loss of $9 million for the three months ended September 30, 2018 compared to operating income of $7 million for the three months ended September 30, 2017.

Operating income decreased $16 million as a result of the following key factors:

a $9 million decrease in margin due to reduced opportunities to optimize natural gas supply costs and timing impacts related to natural gas storage activity, which offset favorable margins from incremental sales volumes.  Lower storage balances resulting from first quarter storage activity reduced opportunities to optimize natural gas supply costs in the third quarter;


a $6 million increase in operation and maintenance expenses, primarily due to higher legal, technology and support services expenses; and

a $1 million decrease from mark-to-market accounting for derivatives associated with certain natural gas purchases and sales used to lock in economic margins.

Nine months ended September 30, 2018 compared to nine months ended September 30, 2017

Our Energy Services business segment reported an operating loss of $20 million for the nine months ended September 30, 2018 compared to operating income of $58 million for the nine months ended September 30, 2017. 

Operating income decreased $78 million as a result of the following key factors:

a $94 million decrease from mark-to-market accounting for derivatives associated with certain natural gas purchases and sales used to lock in economic margins; and

a $9 million increase in operation and maintenance expenses, attributable to increased technology expenses, higher contract and services expense related to pipeline integrity testing, higher support services and legal expenses.

These decreases were partially offset by a $25 million increase in margin due to increased opportunities to optimize natural gas supply costs through storage and transportation capacity, primarily in the first quarter of 2018, and incremental volumes from customers. Realized commercial opportunities attributable to the Continuum and AEM acquisitions and colder than normal weather in several regions of the United States, primarily in the first quarter of 2018, drove incremental sales volumes.

Future Sources and Uses of Cash

The liquidity and capital requirements of the Registrants, other than in connection with the pending Merger with Vectren (see Note 3 to the Interim Condensed Financial Statements), are affected primarily by our results of operations, capital expenditures, debt service requirements, tax payments, working capital needs dividends to parent and various regulatory actions. Our capitalCapital expenditures are expected to be used for investment in infrastructure for electric transmission and distribution operations and natural gas distribution operations.  These capital expenditures are anticipated to maintain reliability and safety, increase resiliency and increase resiliency. Ourexpand our systems through value-added projects. In addition to dividend payments on CenterPoint Energy’s Series A Preferred Stock, Series B Preferred Stock and Common Stock, and in addition to interest payments on debt, the Registrants’ principal anticipated cash requirements for the remaining ninethree months of 2018 include the following:

Off-Balance Sheet Arrangements

Other than Houston Electric’s first mortgage bonds and general mortgage bonds issued as collateral for tax-exempt long-term debt of CenterPoint Energy as discussed below and operating leases, we have no off-balance sheet arrangements.

Regulatory Matters

Brazos Valley Connection Project (CenterPoint Energy and Houston Electric)

WeHouston Electric completed construction on and energized the Brazos Valley Connection in March 2018, ahead of the original June 1, 2018 energization date. The final capital costs of the project were approximately $285 million, which was within the estimated range of approximately $270-$310 million in the PUCT’s original order. We plan to seekHouston Electric applied for interim recovery of the project costs through July 31, 2018 not already included in rates in a filing with the PUCT in the second quarter ofSeptember 2018 and is expected to receive approval for interim recovery in November 2018. Final approval by the PUCT of the project costs will occur in ourHouston Electric’s next base rate case.


Bailey-Jones CreekFreeport Master Plan Project (CenterPoint Energy and Houston Electric)

In April 2017, weHouston Electric submitted a proposal to ERCOT requesting its endorsement of our approximately $250 milliona transmission project in the greater Freeport, Texas area, which includes enhancements to two existing substations and the construction of a new 345 kV double-circuit transmission line.line to be located in the counties of Brazoria, Matagorda and Wharton. On December 12, 2017, weHouston Electric received approval from ERCOT.  In September 2018, Houston Electric filed a certificate of convenience and necessity application with the PUCT that included capital cost estimates for the project that ranged from approximately $482-$695 million, which were higher than the initial cost estimates.  The revised project cost estimates include additional costs associated with the routing of the line to mitigate environmental and other land use impacts and structure design to address soil and coastal wind conditions.  The actual capital costs of the project will depend on those factors as well as other factors, including land acquisition costs, construction costs and the ultimate route approved by the PUCT.  On the request of the PUCT, ERCOT has intervened in the proceeding and anticipateis in the process of reviewing the cost-effectiveness of the proposed project. Houston Electric anticipates that the PUCT will provideissue a final decision in 2019 regardingon the designcertificate of convenience and routenecessity application as early as the third quarter of the project.2019.

Rate Change Applications

WeHouston Electric and CERC are routinely involved in rate change applications before the PUCT.state regulatory authorities.  Those applications include general rate cases, where the entire cost of service of the utility is assessed and reset.  In addition, we areHouston Electric is periodically involved in proceedings to adjust ourits capital tracking mechanisms (TCOS and DCRF) and annually filefiles to adjust ourits EECRF.  CERC is periodically involved in proceedings to adjust its capital tracking mechanisms in Texas (GRIP), its cost of service adjustments in Arkansas, Louisiana, Mississippi and Oklahoma (FRP, RSP, RRA and PBRC, respectively), its decoupling mechanism in Minnesota, and its energy efficiency cost trackers in Arkansas, Minnesota, Mississippi and Oklahoma (EECR, CIP, EECR and EECR, respectively).

Tax Reform

OurFor Houston Electric and CERC’s NGD, federal income tax expense is included in the rates approved by the PUCTstate commissions and local municipalities and charged by those utilities to consumers. As we haveHouston Electric and NGD file general rate cases and other periodic rate adjustments, the impacts of the TCJA (including the lower tax rate and the calculation and amortization of EDIT), along with other increases and decreases in our revenue requirements, will be incorporated into ourHouston Electric’s and NGD’s future rates as allowed by IRS rules. The effect of any potential return of tax savings resulting from the TCJA to consumers may differ depending on how each regulatory body requires us to return such savings. Regulatory commissions across most of Houston Electric’s and NGD’s jurisdictions have issued accounting orders to track or record a regulatory liability for (1) the difference between revenues collected under existing rates and revenues that would have been collected had the existing rates been set using the recently approved federal income tax rates and (2) the balance of EDIT that now exists because of the reduction in federal income tax rates.

On January 25, 2018, the PUCT issued an accounting order in Project No. 47945 directing electric utilities, including us,Houston Electric, to record as a regulatory liability (1) the difference between revenues collected under existing rates and revenues that would have been collected had the existing rates been set using the recently approved federal income tax rates and (2) the balance of EDIT that now exists because of the reduction in federal income tax rates. On February 13, 2018, weHouston Electric and other likely parties to a future rate case announced a settlement that requires usHouston Electric to make (i) a TCOS filing by February 20, 2018 to reflect the change in the federal income tax rate for ourHouston Electric’s transmission rate base through July 31, 2017 and account for certain EDIT (and such filing was timely submitted), (ii) a DCRF filing in April 2018 to reflect the change in the federal income tax rate for ourHouston Electric’s distribution rate base through December 31, 2017 (and such filing was timely submitted) and (iii) a full rate case filing by April 30, 2019. The settlement was presented to the PUCT during its open meeting on February 15, 2018. In response to the settlement, the PUCT did not proceed with a prior proposal to require usHouston Electric to file a rate case in the summer of 2018. The PUCT also amended its prior accounting order to remove the requirement that utilities include carrying costs in the new regulatory liability. Additional information related to tax reform for Houston Electric is described in the table above.

On January 12, 2018, the APSC issued an order in Docket No. 18-006-U opening an investigatory docket into the TCJA and directing utilities, including CERC, to record as a regulatory liability the current and deferred impacts of the TCJA. On July 26, 2018, the APSC issued an order in the investigatory docket requiring CERC to (1) include the reduction in tax expense due to the

January 1, 2018 change in the tax rate from 35% to 21% in the utility’s FRP as a reduction to the revenue requirement; this reduction will be reflected in the utility’s historical year netting process in the 2019 FRP filing;  (2)  file and include all unprotected EDIT, including plant-related unprotected EDIT, in a separate rider within 30 days and refund the entire balance before December 31, 2019; (3) include protected EDIT in the FRP and amortize such amount using the ARAM method; and (4) adjust all other riders impacted by the TCJA changes and apply carrying charges calculated using the pre-tax cost of capital of 6.44% for the amounts related to the TCJA within 30 days of the July 26, 2018 order. On August 24, 2018 CERC filed Rider TCJA in Docket No. 18-050-TF. This rider returns the entire unprotected excess ADIT of approximately $19 million over five months from October 2018 through February 2019. The GMES Rider, which is not currently in effect, was revised to reflect the effects of the TCJA. No other riders were impacted. On September 21, 2018, the APSC approved Rider TCJA as filed, with an effective date of October 1, 2018.

On October 5, 2018, the LPSC Staff filed its Final Report and Recommended Proposed Rule in Docket No. R-34754, which addresses the TCJA. The proposed rule recommends that CERC (1) adjust rates prospectively to reflect the new 21% federal corporate income tax rate; (2) refund to ratepayers 100% of federal corporate income taxes collected that are in excess of the new lower applicable tax rate plus carrying cost at the utility’s WACC over a 12-month period or other period approved by the LPSC; (3) accrue carrying charges on EDIT balances at the utility’s WACC until fully amortized, except to the extent ratepayers are receiving benefits of EDIT as a reduction to rate base; (4) amortize protected EDIT over ARAM and implement through an outside-the-band reduction in rates attributable to the annual amortization; and (5) amortize unprotected EDIT over 24 months or other period approved by the LPSC and implement through an outside-the-band reduction in rates or special tax rider. The LPSC Staff presented this proposed rule to the LPSC for vote at the October 26, 2018 Business & Executive Session. The anticipated implementation date for these TCJA related changes begins December 26, 2018, concurrent with the RSP implementation, with the time frame of the return of unprotected EDIT still to be determined.

On November 6, 2018, within the order approving the 2018 Mississippi RRA, the MPSC ruled that protected EDIT will be amortized over ARAM beginning with the 2019 RRA, unprotected EDIT will be amortized over a three-year period beginning December 1, 2018, and the refund due to the change in tax rate for 2018 billings prior to the 2018 RRA implementation will be a component of the 2019 RRA filing for the 2018 calendar year.

FERC Revised Policy Statement and NOPR (CenterPoint Energy and CERC)

On March 15, 2018, the FERC addressed treatment of federal income tax allowances in FERC-regulated pipeline rates. The FERC issued a Revised Policy Statement stating that it will no longer permit pipelines organized as MLPs to recover an income tax allowance in their cost-of-service rates. The FERC issued the Revised Policy Statement in response to a remand from the U.S. Court of Appeals for the D.C. Circuit in United Airlines v. FERC. On July 18, 2018, the FERC issued an order denying requests for rehearing of its Revised Policy Statement because it is a non-binding policy and parties will have the opportunity to address the policy as applied in future cases. Accordingly, the impacts that such changes may have on the rates Enable can charge for transportation services are unknown at this time.

On March 15, 2018, the FERC also proposed, in a NOPR, the method by which it would apply the Revised Policy Statement to FERC-jurisdictional natural gas pipeline rates, as well as account for the corporate income tax rate reduction in the TCJA. On July 18, 2018, the FERC issued a final rule requiring FERC-regulated natural gas pipelines that have cost-based rates to make a filing providing certain cost and revenue information and then either propose to reduce or support current cost-based rates, or take no further action. The final rule is currently subject to requests for rehearing. Enable Gas Transmission, LLC, an Enable subsidiary and owner of a FERC-regulated interstate natural gas pipeline, made its required filing on October 11, 2018, in which it asserted that no rate reduction is warranted. That filing remains subject to FERC review. Enable’s other interstate pipeline subsidiary, Enable Mississippi River Transmission, LLC, is not required to make such a filing as it is engaged in an ongoing rate case. At this time, we cannot predict the outcome of the final rule on Enable, but it could adversely impact the rates Enable is permitted to charge its customers.

In March 2018, CERC Corp. issued $600 million aggregate principal amount of unsecured senior notes. In October 2018, CenterPoint Energy issued $1.5 billion aggregate principal amount of unsecured senior notes. For further information about our 2018 debt issuances, see Note 812 to ourthe Interim Condensed Financial Statements.

As of March 31,September 30, 2018, ourHouston Electric’s outstanding first mortgage bonds and general mortgage bonds aggregated approximately $3.4 billion, of which $118 million is not reflected in ourits consolidated financial statements because of the contingent nature of the obligation.

The lien of the general mortgage indenture is junior to that of the mortgage pursuant to which the first mortgage bonds are issued. WeHouston Electric may issue additional general mortgage bonds on the basis of retired bonds, 70% of property additions or cash deposited with the trustee.  Approximately $4.0$4.2 billion of additional first mortgage bonds and general mortgage bonds could be issued on the basis of retired bonds and 70% of property additions as of March 31,September 30, 2018.

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

(2)An S&P CreditWatch assesses the potential direction of a short-term or long-term credit rating.

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

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

A decline in credit ratings could increase borrowing costs under ourthe Registrants’ revolving credit facility.facilities. If ourthe Registrants’ credit ratings had been downgraded one notch by each of the three principal credit rating agencies from the ratings that existed as of March 31,September 30, 2018, the impact on the borrowing costs under ourthe three revolving credit facilityfacilities 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 ourthe Registrants’ ability to complete capital market transactions.transactions and to access the commercial paper market. Additionally, a decline in credit ratings could increase cash collateral requirements and reduce earnings of CenterPoint Energy’s and CERC’s Natural Gas Distribution and Energy Services business segments.

CES, a wholly-owned subsidiary of CERC Corp. operating in our Energy Services business segment, provides natural gas sales and services primarily to commercial and industrial customers and electric and natural gas utilities throughout the United States. To economically hedge its exposure to natural gas prices, CES uses derivatives with provisions standard for the industry, including those pertaining to credit thresholds. Typically, the credit threshold negotiated with each counterparty defines the amount of unsecured credit that such counterparty will extend to CES. To the extent that the credit exposure that a counterparty has to CES at a particular time does not exceed that credit threshold, CES is not obligated to provide collateral. Mark-to-market exposure in excess of the credit threshold is routinely collateralized by CES. Similarly, mark-to-market exposure offsetting and exceeding the credit threshold may cause the counterparty to provide collateral to CES. As of September 30, 2018, the amount posted by CES as collateral aggregated approximately $41 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 September 30, 2018, unsecured credit limits extended to CES by counterparties aggregated $268 million, and none 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 $185 million as of September 30, 2018. The amount of collateral will depend on seasonal variations in transportation levels.

ZENS and Securities Related to ZENS (CenterPoint Energy)

If our creditworthiness were to drop such that ZENS holders thought our liquidity was adversely affected or the market for the ZENS were to become illiquid, some ZENS holders might decide to exchange their ZENS for cash. Funds for the payment of cash upon exchange could be obtained from the sale of the shares of ZENS-Related Securities that we own or from other sources. We own shares of ZENS-Related Securities equal to approximately 100% of the reference shares used to calculate our obligation to the holders of the ZENS. ZENS exchanges result in a cash outflow because tax deferrals related to the ZENS and ZENS-Related Securities shares would typically cease when ZENS are exchanged or otherwise retired and ZENS-Related Securities shares are sold. The ultimate tax liability related to the ZENS continues to increase by the amount of the tax benefit realized each year, and there could be a significant cash outflow when the taxes are paid as a result of the retirement of the ZENS. If all ZENS had been exchanged for cash on September 30, 2018, deferred taxes of approximately $410 million would have been payable in 2018. If all the ZENS-Related Securities had been sold on September 30, 2018, capital gains taxes of approximately $109 million would have been payable in 2018. For additional information about ZENS, see Note 11 to the Interim Condensed Financial Statements.

Cross Defaults

Under CenterPoint Energy’s revolving credit facility, a payment default on, or a non-payment default that permits acceleration of, any indebtedness for borrowed money and certain other specified types of obligations (including guarantees) exceeding $125

$125 million by usit or any of its significant subsidiaries will cause a default. A default by CenterPoint Energy would not trigger a default under ourits subsidiaries’ debt instruments or revolving credit facility.

facilities.

Possible Acquisitions, Divestitures and Joint Ventures or Dispositions

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

Enable Midstream Partners (CenterPoint Energy and CERC)

In September 2018, CERC completed the Internal Spin, after which CERC’s equity investment in Enable met the criteria for discontinued operations classification. As a result, the operations have been classified as Income from discontinued operations, net of tax, in CERC’s Condensed Statements of Consolidated Income for the periods presented. For further information, see Note 9 to the Interim Condensed Financial Statements.

CenterPoint Energy receives quarterly cash distributions from Enable on its common units and Enable Series A Preferred Units. A reduction in the cash distributions CenterPoint Energy receives from Enable could significantly impact CenterPoint Energy’s liquidity. For additional information about cash distributions from Enable, see Notes 9 and 20 to the Interim Condensed Financial Statements.

Hedging of Interest Expense for Future Debt Issuances

During the first quarter of 2018,From time to time, we enteredmay enter into forward interest rate agreements to hedge, in part, volatility in the U.S. treasury rates by reducing variability in cash flows related to interest payments. For further information, see Note 87(a) to the Interim Condensed Financial Statements.

Weather Hedge (CenterPoint Energy and CERC)

We have historically entered into partial weather hedges for certain NGD jurisdictions and electric operations’ service territory to mitigate the impact of fluctuations from normal weather. We remain exposed to some weather risk as a result of the partial hedges. For more information about our weather hedges, see Note 7(a) to the Interim Condensed Financial Statements.

Collection of Receivables from REPs (CenterPoint Energy and Houston Electric)

OurHouston Electric’s receivables from the distribution of electricity are collected from REPs that supply the electricity we distributeHouston Electric distributes to their customers. Before conducting business, a REP must register with the PUCT and must meet certain financial qualifications. Nevertheless, 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 ourHouston Electric’s services or could cause them to delay such payments. We dependHouston Electric depends on these REPs to remit payments on a timely basis, and any delay or default in payment by REPs could adversely affect ourHouston Electric’s cash flows. In the event of a REP’s default, ourHouston Electric’s tariff provides a number of remedies, including ourthe option for Houston Electric to request that the PUCT suspend or revoke the certification of the REP. Applicable regulatory provisions require that customers be shifted to another REP or a provider of last resort if a REP cannot make timely payments. However, we remainHouston Electric remains at risk for payments related to services provided prior to the shift to the replacement REP or the provider of last resort. If a REP were unable to meet its obligations, it could consider, among various options, restructuring under the bankruptcy laws, in which event such REP might seek to avoid honoring its obligations and claims might be made against usHouston Electric involving payments weit had received from such REP. If a REP were to file for bankruptcy, weHouston Electric may not be successful in recovering accrued receivables owed by such REP that are unpaid as of the date the REP filed for bankruptcy. However, PUCT regulations authorize utilities, such as us,Houston Electric, 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 weather hedging arrangements, and natural gas purchases, natural gas price and natural gas storage activities of the 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 natural 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 our credit facility;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, currently the subject of bankruptcy proceedings, to satisfy their obligations in respect of GenOn’sto us, including indemnity obligations, to us;which may be contested by GenOn;

the ability of REPs, including REP affiliates of NRG and Vistra Energy Corp., formerly known as TCEH Corp., to satisfy their obligations to us;CenterPoint Energy and Houston Electric;

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

the outcome of litigation brought by or against us;litigation; 

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 oureach of the Registrants’ 2017 Form 10-K.

10-K and Item 1A of Part II of CenterPoint Energy’s First Quarter 2018 Form 10-Q.

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

For information about the total debt to capitalization financial covenants in our revolving credit facility,facilities, see Note 812 to ourthe Interim Condensed Financial Statements.

Relationship with CenterPoint Energy

We are an indirect, wholly-owned subsidiary of CenterPoint Energy. As a result of this relationship, the financial condition and liquidity of our parent company could affect our access to capital, our credit standing and our financial condition.

NEW ACCOUNTING PRONOUNCEMENTS

See Note 2 to ourthe Interim Condensed Financial Statements, incorporated herein by reference, for a discussion of new accounting pronouncements that affect us.

Item 3.QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest Rate Risk (CenterPoint Energy)

As of September 30, 2018, 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 $202 million and $1.8 billion as of September 30, 2018 and December 31, 2017, respectively. If the floating interest rates were to increase by 10% from September 30, 2018 rates, our combined interest expense would increase by less than $1 million annually.


As of September 30, 2018 and December 31, 2017, we had outstanding fixed-rate debt (excluding indexed debt securities) aggregating $7.6 billion and $7.0 billion, respectively, in principal amount and having a fair value of $7.8 billion and $7.5 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. However, the fair value of these instruments would increase by approximately $263 million if interest rates were to decline by 10% from levels at September 30, 2018. 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 prior to their maturity.

The ZENS obligation is bifurcated into a debt component and a derivative component. The debt component of $25 million as of September 30, 2018 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 $8 million if interest rates were to decline by 10% from levels at September 30, 2018. Changes in the fair value of the derivative component, a $685 million recorded liability at September 30, 2018, are recorded in our Condensed 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 September 30, 2018 levels, the fair value of the derivative component liability would decrease by approximately $2 million, which would be recorded as an unrealized gain in our Condensed Statements of Consolidated Income.

Equity Market Value Risk (CenterPoint Energy)

We are exposed to equity market value risk through our ownership of 10.2 million shares of AT&T Common and 0.9 million shares of Charter Common, which we hold to facilitate our ability to meet our obligations under the ZENS. Changes in the fair value of the ZENS-Related Securities held by CenterPoint Energy are expected to substantially offset changes in the fair value of the derivative component of the ZENS. A decrease of 10% from the September 30, 2018 aggregate market value of these shares would result in a net loss of approximately less than $1 million, which would be recorded as an unrealized loss in our Condensed Statements of Consolidated Income.

Commodity Price Risk From Non-Trading Activities (CenterPoint Energy and CERC)

We use derivative instruments as economic hedges to offset the commodity price exposure inherent in our businesses. The commodity risk created by these instruments, including the offsetting impact on the market value of natural gas inventory, is described below. We measure this commodity risk using a sensitivity analysis. For purposes of this analysis, we estimate commodity price risk by applying a $0.50 change in the forward NYMEX price to our net open fixed price position (including forward fixed price physical contracts, natural gas inventory and fixed price financial contracts) at the end of each period. As of September 30, 2018, the recorded fair value of our non-trading energy derivatives was a net asset of $51 million (before collateral), all of which is related to our Energy Services business segment. A $0.50 change in the forward NYMEX price would have had a combined impact of $7 million on our non-trading energy derivatives net asset and the market value of natural gas inventory.

Commodity price risk is not limited to changes in forward NYMEX prices. Variation of commodity pricing between the different indices used to mark to market portions of our natural gas inventory (Gas Daily) and the related fair value hedge (NYMEX) can result in volatility to our net income. Over time, any gains or losses on the sale of storage gas inventory would be offset by gains or losses on the fair value hedges.

Item 4.CONTROLS AND PROCEDURES

In accordance with Exchange Act Rules 13a-15 and 15d-15, wethe Registrants carried out an evaluation,separate evaluations, under the supervision and with the participation of each company’s management, including ourthe principal executive officer and principal financial officer, of the effectiveness of ourthe disclosure controls and procedures as of the end of the period covered by this report. Based on that evaluation, ourthose evaluations, the principal executive officer and principal financial officer, in each case, concluded that ourthe disclosure controls and procedures were effective as of March 31,September 30, 2018 to provide assurance that information required to be disclosed in ourthe reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and such information is accumulated and communicated to our management, including ourthe principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding disclosure.

There has been no change in ourthe Registrants’ internal controlcontrols over financial reporting that occurred during the three months ended March 31,September 30, 2018 that has materially affected, or is reasonably likely to materially affect, ourthe Registrants’ internal controlcontrols over financial reporting.
