CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING INFORMATION

From time to time we make statements concerning our expectations, beliefs, plans, objectives, goals, strategies, future events or performance and underlying assumptions and other statements that are not historical facts. These statements are “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Actual results may differ materially from those expressed or implied by these statements.

Therefore, we cannot assure you that actual results will not differ materially from those expressed or implied by our forward-looking statements.

The following are some of the factors that could cause actual results to differ from those expressed or implied by our forward-looking statements:

iv

the impact of unplanned facility outages;

any direct or indirect effects on our facilities, operations and financial condition resulting from terrorism, cyber-attacks, data security breaches or other attempts to disrupt our businesses or the businesses of third parties, or other catastrophic events such as fires, earthquakes, explosions, leaks, floods, droughts, hurricanes, pandemic health events or other occurrences;

acquisition and merger activities involving us or our competitors;

our or Enable’s ability to recruit, effectively transition and retain management and key employees and maintain good labor relations;

CENTERPOINT ENERGY, INC. AND SUBSIDIARIES

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(1) Background and Basis of Presentation

General. Included in this Form 10-Q are the Interim Condensed Financial Statements of CenterPoint Energy. The Interim Condensed Financial Statements are unaudited, omit certain financial statement disclosures and should be read with the 2016 Form 10-K.

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

Houston Electric, which engages in the electric transmission and distribution business in the Texas Gulf Coast area that includes the city of Houston;

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

CES, which obtains and offers competitive variable and fixed-price physical natural gas supplies and services primarily to commercial and industrial customers and electric and natural gas utilities in 33 states.

As of March 31,September 30, 2017, CenterPoint Energy also owned an aggregate of 14,520,000 Series A Preferred Units in Enable, which owns, operates and develops natural gas and crude oil infrastructure assets, and CERC Corp. owned approximately 54.1% of the common and subordinated units representing limited partner interests in Enable.

As of March 31,September 30, 2017, CenterPoint Energy had VIEs consisting of the Bond Companies, which it consolidates. The consolidated VIEs are wholly-owned, bankruptcy-remote, special purpose entities that were formed specifically for the purpose of securitizing transition and system restoration-related property. Creditors of CenterPoint Energy have no recourse to any assets or revenues of the Bond Companies. The bonds issued by these VIEs are payable only from and secured by transition and system restoration property, and the bondholders have no recourse to the general credit of CenterPoint Energy.

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.

CenterPoint Energy’s 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 CenterPoint Energy’s 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 (d) acquisitions and dispositions of businesses, assets and other interests.

For a description of CenterPoint Energy’s reportable business segments, see Note 15.

(2) New Accounting Pronouncements

In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments-Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities (ASU 2016-01). ASU 2016-01 requires equity investments that do not result in consolidation and are not accounted for under the equity method to be measured at fair value and to recognize any changes in fair value in net income unless the investments qualify for the new practicability exception. It does not change the guidance for classifying and measuring investments in debt securities and loans. ASU 2016-01 also changes certain disclosure requirements and other aspects related to recognition and measurement of financial assets and financial liabilities. ASU 2016-01 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017. As of the first reporting period in which the guidance is adopted, a cumulative-effect adjustment to beginning retained earnings will be made, with two features that will be adopted prospectively. CenterPoint Energy does not believe this standard will have a material impact on its financial position, results of operations, cash flows and disclosures.


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

In March 2016, the FASB issued ASU No. 2016-09, Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting (ASU 2016-09).  The new guidance simplifies several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. CenterPoint Energy adopted this standard as of January 1, 2017. The adoption did not have a material impact on CenterPoint Energy’s financial position or results of operations.  However, CenterPoint Energy’s statement of cash flows reflects a decrease in financing activity and a corresponding increase in operating activity of $4 million and $3 million as of March 31,September 30, 2017 and March 31, 2016, respectively, due to the retrospective application of the requirement that cash paid to a tax authority when shares are withheld to satisfy statutory income tax withholding obligations should be presented as a financing rather than as an operating activity.

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

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

In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash (ASU 2016-18). ASU 2016-18 requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, restricted cash and restricted cash equivalents. As a result, the statement of cash flows will no longer present transfers between cash and cash equivalents and restricted cash and restricted cash equivalents. When cash, cash equivalents, restricted cash and restricted cash equivalents are presented in more than one line item on the balance sheet, the new guidance requires a reconciliation of the totals in the statement of cash flows to the related captions in the balance sheet. ASU 2016-18 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017, with early adoption permitted. A retrospective adoption approach is required. CenterPoint Energy is currently assessing the impact that thisThis standard will not have an impact on itsCenterPoint Energy’s financial position, results of operations, and disclosures, but it will have an impact on the presentation of the statement of cash flows and disclosures.flows.

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

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


In February 2017, the FASB issued ASU No. 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 (ASU 2017-05). ASU 2017-05 clarifies when and how to apply ASC 610-20 Gains and Losses from the Derecognition of Nonfinancial Assets, which was issued as part of ASU 2014-09 Revenue from Contracts with Customers (Topic 606). ASU 2017-05 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017, with early adoption permitted. Companies can elect a retrospective or modified retrospective approach to adoption. CenterPoint Energy is currently assessing the impact thatdoes not believe this standard will have a material impact on its financial position, results of operations, cash flows and disclosures.

In March 2017, the FASB issued ASU No. 2017-07, Compensation-Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost (ASU 2017-07). ASU 2017-07 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. ASU 2017-07 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017, with early adoption permitted. ASU 2017-07 should be applied retrospectively for the presentation of the service cost component and the other components and prospectively for the capitalization of the service cost component. The adoption of this guidance is expected to result in an increase to operating income and a decrease to other income. Prospectively, other components previously capitalized in assets will be recorded as regulatory assets in CenterPoint Energy’s rate-regulated businesses. CenterPoint Energy does not believe this standard will have a material impact on its financial position, results of operations, cash flows and disclosures.

In May 2017, the FASB issued ASU No. 2017-09, Compensation-Stock Compensation (Topic 718): Scope of Modification Accounting (ASU 2017-09). ASU 2017-09 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. ASU 2017-09 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017, with early adoption permitted. ASU 2017-09 should be applied prospectively for awards modified on or after the adoption date. This standard will have an impact on CenterPoint Energy’s future treatment of changes to share-based payment awards.

In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities (ASU 2017-12). ASU 2017-12 expands an entity’s ability to hedge nonfinancial and financial risk components and reduce complexity in fair value hedges of interest rate risk. The guidance eliminates the requirement to separately measure and report hedge ineffectiveness, eases certain documentation and assessment requirements, and updates the presentation and disclosure requirements. ASU 2017-12 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018, with early adoption permitted. A cumulative-effect adjustment to eliminate the separate measurement of ineffectiveness upon adoption is required for existing cash flow and net investment hedges. Presentation and disclosure guidance should be applied prospectively. CenterPoint Energy is currently assessing the impact that this standard will have on its financial position, results of operations, cash flows and disclosures.

Management believes that other recently issued standards, which are not yet effective, will not have a material impact on CenterPoint Energy’s consolidated financial position, results of operations or cash flows upon adoption.

(3) Acquisition

On January 3, 2017, CES, an indirect, wholly-owned subsidiary of CenterPoint Energy, closed the previously announced agreement to acquirecompleted its acquisition of AEM. After working capital adjustments, the final purchase price was $147 million and was allocated to identifiable assets acquired and liabilities assumed based on their estimated fair values on the acquisition date.


The following table summarizes the final purchase price allocation and the fair value amounts recognized for the assets acquired and liabilities assumed related to the acquisition:
  (in millions)
Total purchase price consideration $147
Cash $15
Receivables 140
Natural gas inventory 78
Derivative assets 35
Prepaid expenses and other current assets 5
Property and equipment 8
Identifiable intangibles 25
Total assets acquired 306
Accounts payable 113
Derivative liabilities 43
Other current liabilities 7
Other liabilities 1
Total liabilities assumed 164
Identifiable net assets acquired 142
Goodwill 5
Net assets acquired $147

The goodwill of $5 million resulting from the acquisition reflects the excess of the purchase price over the fair value of the net identifiable assets acquired. The goodwill recorded as part of the acquisition primarily reflects the value of the complementary operational and geographic footprints, scale and expanded capabilities provided by the acquisition.


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

The estimated fair value of the identifiable intangible assets and related useful lives as included in the final purchase price allocation include:
  Estimate Fair Value Estimate Useful Life
  (in millions) (in years)
Customer relationships $25
 15

Amortization expense related to the above identifiable intangible assets was less than$-0- and $1 million for the three and nine months ended March 31, 2017.September 30, 2017, respectively.

Revenues of approximately $359$311 million and $989 million, respectively, and operating income of approximately $17$3 million and $28 million, respectively, attributable to the AEM acquisition are reported in the Energy Services business segment and included in CenterPoint Energy’s Condensed Statements of Consolidated Income for the three and nine months ended March 31,September 30, 2017.

The following unaudited pro forma financial information reflects the consolidated results of operations of CenterPoint Energy, assuming the AEM acquisition had taken place on January 1, 2016. Adjustments to pro forma net income include intercompany sales, amortization of intangible assets, depreciation of fixed assets, interest expense associated with debt financing to fund the acquisition, and related income tax effects. The pro forma information does not include the mark-to-market impact of financial instruments designated as cash flow hedges of anticipated purchases and sales at index prices. The effective portion of these hedges are excluded from earnings and reported as changes in Other Comprehensive Income. Additionally, the pro forma information does not include the mark-to-market impact of physical forward transactions that were previously accounted for as normal purchase and sale transactions.

The unaudited pro forma financial information has been presented for illustrative purposes only and is not necessarily indicative of the consolidated results of operations that would have been achieved had the acquisition taken place on the dates indicated or the future consolidated results of operations of the combined company.

(1)A curtailment gain or loss is required when the expected future services of a significant number of current employees are reduced or eliminated for the accrual of benefits. In May 2016, Houston Electric entered into a renegotiated collective bargaining agreement with the IBEW Local Union 66 that provides that for Houston Electric union employees covered under the agreement who retire on or after January 1, 2017, retiree medical and prescription drug coverage will be provided exclusively through the NECA/IBEW Family Medical Care Plan in exchange for the payment of monthly premiums as determined under the agreement. As a result, the accrued postretirement benefits related to such future Houston Electric union retirees were eliminated. In 2016, Houston Electric recognized a curtailment gain of $3 million as an accelerated recognition of the prior service credit that would otherwise be recognized in future periods.

(2)Net periodic cost in this table is before considering amounts subject to overhead allocations for capital expenditure projects or for amounts subject to deferral for regulatory purposes.  


CenterPoint Energy’s changes in accumulated comprehensive loss related to defined benefit and postretirement plans are as follows:

CenterPoint Energy expects to contribute a minimum of approximately $46 million to its pension plans in 2017, of which approximately $2$28 million wasand $46 million were contributed during the three and nine months ended March 31, 2017.September 30, 2017, respectively.

CenterPoint Energy expects to contribute a total of approximately $16 million to its postretirement benefit plan in 2017, of which approximately $4 million wasand $12 million were contributed during the three and nine months ended March 31, 2017.September 30, 2017, respectively.

(5) Regulatory Accounting

Equity Return.As of March 31,September 30, 2017, Houston Electric has not recognized an allowed equity return of $322$299 million because such return will be recognized as it is recovered in rates. During the three months ended March 31,September 30, 2017 and 2016, Houston Electric recognized approximately $7$13 million and $13$22 million, respectively, of the allowed equity return not previously recognized. During the nine months ended September 30, 2017 and 2016, Houston Electric recognized approximately $30 million and $52 million, respectively, of the allowed equity return not previously recognized.

Hurricane Harvey. Houston Electric’s electric delivery system and CERC Corp.’s NGD suffered damage as a result of Hurricane Harvey, a major storm classified as a Category 4 hurricane on the Saffir-Simpson Hurricane Wind Scale, that first struck the Texas coast on Friday, August 25, 2017 and remained over the Houston area for the next several days. The unprecedented flooding from torrential amounts of rainfall accompanying the storm caused significant damage to or destruction of residences and businesses served by Houston Electric and NGD.

Currently, Houston Electric estimates that total costs to restore the electric delivery facilities damaged as a result of Hurricane Harvey will range from $110 million to $120 million and estimates that the total restoration costs covered by insurance will be approximately $35 million. Houston Electric will defer the uninsured storm restoration costs as management believes it is probable that such costs will be recovered through traditional rate adjustment mechanisms for capital costs and through the next rate proceeding for operation and maintenance expenses. As of September 30, 2017, Houston Electric recorded an increase of $4 million in property, plant and equipment and $73 million in regulatory assets, net of $23 million in insurance receivables recorded, for restoration costs incurred.  As a result, storm restoration costs should not materially affect Houston Electric’s reported net income for 2017.

Currently, NGD estimates that total costs to restore natural gas distribution facilities damaged as a result of Hurricane Harvey will range from $25 million to $30 million and estimates that the total restoration costs covered by insurance will be approximately $17 million.  NGD will defer the uninsured storm restoration costs as management believes it is probable that such costs will be recovered through traditional rate adjustment mechanisms for capital costs and through the next rate proceeding for operation and maintenance expenses. As of September 30, 2017, NGD has recorded approximately $7 million in regulatory assets, net of $2

million of insurance receivables recorded, for restoration costs incurred. As a result, storm restoration costs should not materially affect CERC’s reported net income for 2017.

(6) Derivative Instruments

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

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

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

(a)Non-Trading Activities

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

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

CenterPoint Energy entered into heating-degree day swaps for certain NGD Texas jurisdictions to mitigate the effect of fluctuations from normal weather on its results of operations and cash flows for the 2017–2018 winter heating season, which contained a bilateral dollar cap of $8 million. However, CenterPoint Energy did not enter into heating-degree day swaps for NGD jurisdictions for the 2015–2016 or 2016–2017 winter heating seasons. CenterPoint Energy entered into weather hedges for the Houston Electric service territory to mitigate the effect of fluctuations from normal weather on its results of operations and cash flows, which contained bilateral dollar caps of $7 million, $9 million and $9 million for the 2015–2016, 2016–2017 and 2016–20172017–2018 winter seasons, respectively. The swaps are based on cooling degree days and heating degree days at 10-year normal weather. During both the three months ended March 31,September 30, 2017 and 2016, CenterPoint Energy recognized no gains or losses related to these swaps. During the nine months ended September 30, 2017 and 2016, CenterPoint Energy recognized gains of $1 million and $3 million, respectively, related to these swaps. Weather hedge gains and losses are included in revenues in the Condensed Statements of Consolidated Income.

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

In March and April 2017, CenterPoint Energy entered into forward interest rate agreements with several counterparties, having an aggregate notional amount of $250$350 million. These agreements were executed to hedge, in part, volatility in the 5-year U.S. treasury rate by reducing CenterPoint Energy’s exposure to variability in cash flows relating to interest payments on a forecastedof CenterPoint Energy’s $500 million issuance of fixed rate debt in August 2017. These forward interest rate agreements were designated as cash flow hedges. As of March 31, 2017, an approximately $1 million current non-trading derivative liability was recorded on the Condensed Consolidated Balance Sheets related to these agreements.

Accordingly, the effective portion of unrealized gains andrealized losses associated with the forward interest rate agreements, will be recorded aswhich totaled approximately $2.9 million, is a component of accumulated other comprehensive income in 2017 and the ineffective portion will be recordedamortized over the life of the notes.

In August 2017, CERC Corp. entered into forward interest rate agreements with several counterparties, having an aggregate notional amount of $150 million. These agreements were executed to hedge, in income.part, volatility in the 30-year U.S. treasury rate by reducing CERC Corp.’s exposure to variability in cash flows related to interest payments of CERC Corp.’s $300 million issuance of fixed rate debt in August 2017. These forward interest rate agreements were designated as cash flow hedges. Accordingly, the effective portion of realized losses associated with the agreements, which totaled approximately $1.5 million, is a component of accumulated other comprehensive income in 2017 and will be amortized over the life of the notes.

Realized and unrealized gains and losses on natural gas derivatives are recognized in the Condensed Statements of Consolidated Income as revenue for retailphysical sales derivative contracts and as natural gas expense for financial natural gas derivatives and non-retail related physical purchase natural gas derivatives. Realized and unrealized gains and losses on indexed debt securities are recorded as Other Income (Expense) in the Condensed Statements of Consolidated Income.

Hedge ineffectiveness is recorded as a component of natural gas expense and primarily results from differences in the location of the derivative instrument and the hedged item. Basis ineffectiveness arises from natural gas market price differences between the locations of the hedged inventory and the delivery location specified in the hedge instruments. The impact of natural gas derivatives designated as fair value hedges, the related hedged item, and natural gas derivatives not designated as hedging instruments are presented in the table below.

(1)Hedge ineffectiveness results from the basis ineffectiveness discussed above, and excludes the impact to natural gas expense from timing ineffectiveness.  Timing ineffectiveness arises due to changes in the 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.  As the commodity contract nears the settlement date, spot-to-forward price differences should converge, which should reduce or eliminate the impact of this ineffectiveness on natural gas expense.


(c)Credit Risk Contingent Features

CenterPoint Energy enters into financial derivative contracts containing material adverse change provisions.  These provisions could require CenterPoint Energy to post additional collateral if the S&P or Moody’s credit ratings of CenterPoint Energy, Inc. or

its subsidiaries are downgraded.  The total fair value of the derivative instruments that contain credit risk contingent features that are in a net liability position as of March 31,both September 30, 2017 and December 31, 2016 was $2 million and $1 million, respectively.million.  CenterPoint Energy posted no assets as collateral towardstoward derivative instruments that contain credit risk contingent features as of either March 31,September 30, 2017 or December 31, 2016.  If all derivative contracts (in a net liability position) containing credit risk contingent features were triggered as of March 31,September 30, 2017 and December 31, 2016, $1 million and $-0-, respectively, of additional assets would be required to be posted as collateral.

(7) Fair Value Measurements

Assets and liabilities that are recorded at fair value in the 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 exchange-traded derivatives and equity securities, as well as natural gas inventory that has been designated as the hedged item in 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. Fair value assets and liabilities that are generally included in this category are derivatives with fair values based on inputs from actively quoted markets.  A market approach is utilized to value CenterPoint Energy’s Level 2 assets or liabilities.

Level 3: Inputs are unobservable for the asset or liability, and include situations where there is little, if any, market activity for the asset or liability. Unobservable inputs reflect CenterPoint Energy’s judgments about the assumptions market participants would use in pricing the asset or liability since limited market data exists. CenterPoint Energy develops these inputs based on the best information available, including CenterPoint Energy’s own data. A market approach is utilized to value CenterPoint Energy’s Level 3 assets or liabilities. As of March 31,September 30, 2017, CenterPoint Energy’s Level 3 assets and liabilities are comprised of physical natural gas forward contracts and options and its indexed debt securities. Level 3 physical natural gas forward contracts are valued using a discounted cash flow model which includes illiquid forward price curve locations (ranging from $1.90$1.08 to $6.05$5.83 per MMBtu) as an unobservable input. Level 3 options are valued through Black-Scholes (including forward start) option models which include option volatilities (all zero volatility options as of March 31, 2017)(ranging from 0% to 87%) as an unobservable input.  CenterPoint Energy’s Level 3 physical natural gas forward contracts and options derivative assets and liabilities consist of both long and short positions (forwards and options) and their fair value is sensitive to forward prices and volatilities. If forward prices decrease, CenterPoint Energy’s long forwards lose value whereas its short forwards gain in value.  If volatility decreases, CenterPoint Energy’s long options lose value whereas its short options gain in value. CenterPoint Energy’s Level 3 indexed debt securities are valued using a Black-Scholes option model and a discounted cash flow model, which use option volatility (16%(11.4%) and a projected dividend growth rate (7%) as unobservable inputs. An increase in either volatilities or projected dividends will increase the value of the indexed debt securities, and a decrease in either the volatilities or projected dividends will decrease the value of the indexed debt securities.

CenterPoint Energy determines the appropriate level for each financial asset and liability on a quarterly basis and recognizes transfers between levels at the end of the reporting period.  For the threenine months ended March 31,September 30, 2017, there were no transfers between Level 1 and 2. CenterPoint Energy also recognizes purchases of Level 3 financial assets and liabilities at their fair market value at the end of the reporting period.


The following tables present information about CenterPoint Energy’s assets and liabilities (including derivatives that are presented net) measured at fair value on a recurring basis as of March 31,September 30, 2017 and December 31, 2016, and indicate the fair value hierarchy of the valuation techniques utilized by CenterPoint Energy to determine such fair value.

(3)
During 2016, CenterPoint Energy transferred its indexed debt securities from Level 2 to Level 3 to reflect changes in the significance of the unobservable inputs used in the valuation. As of March 31,September 30, 2017, the indexed debt securities liability was $727$776 million. During the three and nine months ended March 31,September 30, 2017, there was a loss of $10$36 million and $59 million, respectively, on the indexed debt securities.

Estimated Fair Value of Financial Instruments

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

As of March 31,September 30, 2017, CERC Corp. and OGE also own 40% and 60%, respectively, of the incentive distribution rights held by the general partner of Enable. Enable is expected to pay a minimum quarterly distribution of $0.2875 per common unit on its outstanding common units (other than the Series A Preferred Units) to the extent it has sufficient cash from operations after establishment of cash reserves and payment of fees and expenses, including payments to its general partner and its affiliates, within 60 days after the end of each quarter. If cash distributions to Enable’s unitholders exceed $0.330625 per common unit (other than the Series A Preferred Units) in any quarter, the general partner will receive increasing percentages or incentive distributions rights, up to 50%, of the cash Enable distributes in excess of that amount. In certain circumstances the general partner of Enable will have the right to reset the minimum quarterly distribution and the target

distribution levels at which the incentive distributions receive increasing percentages to higher

levels based on Enable’s cash distributions at the time of the exercise of this reset election. To date, no incentive distributions have been made.

CenterPoint Energy performs its goodwill impairment tests at least annually and evaluates goodwill when events or changes in circumstances indicate that its carrying value may not be recoverable. The impairment evaluation for goodwill is performed using a two-step process. In the first step, the fair value of each reporting unit is compared with the carrying amount of the reporting unit, including goodwill. The estimated fair value of the reporting unit is generally determined on the basis of discounted cash flows. If the estimated fair value of the reporting unit is less than the carrying amount of the reporting unit, then a second step must be completed to determine the amount of the goodwill impairment that should be recorded. In the second step, the implied fair value of the reporting unit’s goodwill is determined by allocating the reporting unit’s fair value to all of its assets and liabilities other than goodwill (including any unrecognized intangible assets) in a manner similar to a purchase price allocation. The resulting implied fair value of the goodwill that results from the application of this second step is then compared to the carrying amount of the goodwill and an impairment charge is recorded for the difference.
CenterPoint Energy performed its annual impairment test in the third quarter of 2017 and determined, based on the results of the first step, that no impairment charge was required for any reportable segment.

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

(a) Investment in Securities Related to ZENS

In 1995, CenterPoint Energy sold a cable television subsidiary to TW and received TW securities as partial consideration. A subsidiary of CenterPoint Energy now holds 7.1 million shares of TW Common, 0.9 million shares of Time Common and 0.9 million shares of Charter Common, which are classified as trading securities and are expected to be held to facilitate CenterPoint Energy’s ability to meet its obligation under the ZENS. Unrealized gains and losses resulting from changes in the market value of the TW Securities are recorded in CenterPoint Energy’s 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 March 31,September 30, 2017. 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. As of March 31,September 30, 2017, the reference shares for each ZENS consisted of 0.5 share of TW Common, 0.0625 share of Time Common and 0.061382 share of Charter Common, and the contingent principal balance was $512$507 million.

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. Pursuant to the merger agreement, upon closing of the merger, TW shareholders would receive for each of their shares of TW Common an estimated implied value of $107.50, comprised of $53.75 per share in cash and $53.75 per share in AT&T Common. The stock portion will be subject to a collar such that TW shareholders will receive 1.437 shares of AT&T Common if AT&T Common’s average stock price is below $37.411 at closing and 1.3 shares of AT&T Common if AT&T Common’s average stock price is above $41.349 at

closing. Cash received for the TW Common reference shares would subsequently be distributed to ZENS holders, which is expected to reduce the contingent principal balance, and reference shares would consist of Charter Common, Time Common and AT&T Common. AT&T has publicly announced that the merger is expected to close by the end of 2017.

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

(a)Short-term Borrowings

Inventory Financing. NGD currently has AMAs associated with its utility distribution service in Arkansas, north Louisiana and Oklahoma that extend through 2020. Pursuant to the provisions of the agreements, NGD sells natural gas and agrees to repurchase an equivalent amount of natural gas during the winter heating seasons at the same cost, plus a financing charge. These transactions are accounted for as an inventory financing and had an associated principal obligation of $-0-$48 million and $35 million as of March 31,September 30, 2017 and December 31, 2016, respectively.


(b)Long-term Debt

Debt Retirements.  In February 2017, CenterPoint Energy retired $250 million aggregate principal amount of its 5.95% senior notes at their maturity. The retirement of senior notes was financed by the issuance of commercial paper.

Debt Issuances. During the threenine months ended March 31,September 30, 2017, CenterPoint Energy, Houston Electric and CERC Corp. issued the following general mortgage bonds:debt instruments:
Issuance Date Aggregate Principal Amount Interest Rate Maturity Date
  (in millions)    
January 2017 $300

The proceeds from the issuance of these bondsissuances were used to repay short-term debt and for general limited liability company purposes.and corporate purposes, as applicable, including to repay portions of outstanding commercial paper.

Credit Facilities. In June 2017, CenterPoint Energy, Houston Electric and CERC Corp. each entered into amendments to their respective revolving credit facilities to extend the termination date thereof from March 3, 2021 to March 3, 2022 and to terminate the swingline loan subfacility thereunder. The amendments to the CenterPoint Energy and CERC Corp. revolving credit facilities also increased the aggregate commitments by $100 million and $300 million, respectively, to $1.7 billion and $900 million under their respective revolving credit facilities. No changes were made to the aggregate commitments under the Houston Electric revolving credit facility. In connection with the amendments to increase the aggregate commitments under their respective revolving credit facilities, CenterPoint Energy and CERC Corp. each increased the size of their respective commercial paper programs to permit the issuance of commercial paper notes in an aggregate principal amount not to exceed $1.7 billion and $900 million, respectively, at any time outstanding.

As of March 31,September 30, 2017 and December 31, 2016, CenterPoint Energy, Houston Electric and CERC Corp. had the following revolving credit facilities and utilization of such facilities:

Such temporary increase in the financial covenant would be in effect from the date CenterPoint Energy delivers its certification until the earliest to occur of (i) the completion of the securitization financing, (ii) the first anniversary of CenterPoint Energy’s certification or (iii) the revocation of such certification.

(5)Amended on June 16, 2017 to extend the termination date as noted above.

CenterPoint Energy, Houston Electric and CERC Corp. were in compliance with all financial debt covenants as of March 31,September 30, 2017.

(12) Income Taxes

The effective tax rate reported for both the three months ended March 31,September 30, 2017 and 2016was 37% compared to 35% for the same period in 2016. The higher effective tax rate for the three months ended September 30, 2017 was primarily due to the tax effects of receiving less nontaxable income in the period. The effective tax rate reported for the nine months ended September 30, 2017 was 36%. compared to 37% for the same period in 2016.

CenterPoint Energy reported no uncertain tax liability as of March 31,September 30, 2017 and expects no significant change to the uncertain tax liability over the next twelve months. Tax years through 20142015 have been audited and settled with the IRS. For the 2015-20172016 and 2017 tax years, CenterPoint Energy is a participant in the IRS’s Compliance Assurance Process.

(13) Commitments and Contingencies

(a)Natural Gas Supply Commitments

Natural gas supply commitments include natural gas contracts related to CenterPoint Energy’s Natural Gas Distribution and Energy Services business segments, which have various quantity requirements and durations, that are not classified as non-trading derivative assets and liabilities in CenterPoint Energy’s Condensed Consolidated Balance Sheets as of March 31,September 30, 2017 and December 31, 2016 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 March 31,September 30, 2017, minimum payment obligations for natural gas supply commitments are approximately:

(b)Legal, Environmental and Other Matters

Legal Matters

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

A large number of lawsuits were filed against numerous gas market participants in a number of federal and western state courts in connection with the operation of the natural gas markets in 2000–2002. CenterPoint Energy and its affiliates have since been released or dismissed from all such cases. CES, a subsidiary of CERC Corp., was a defendant in a case now pending in federal court in Nevada alleging a conspiracy to inflate Wisconsin natural gas prices in 2000–2002. On May 24, 2016, the district court granted CES’s motion for summary judgment, dismissing CES from the case. The plaintiffs have appealed that ruling. CenterPoint Energy and CES intend to continue vigorously defending against the plaintiffs’ claims. CenterPoint Energy does not expect the ultimate outcome of this matter to have a material adverse effect on its financial condition, results of operations or cash flows.

In June 2017, GenOn has publicly disclosed that it may be unable to continue as a going concern and is exploring various options, including negotiations with creditors and lessors, refinancing, potential sale of assets, as well as the possibility of filingaffiliates filed for protection under Chapter 11 of the U.S. Bankruptcy Code. CenterPoint Energy, CERC, and CES submitted proofs of claim in the bankruptcy proceedings to protect their indemnity rights. If GenOn were unable to meet its indemnity obligations or satisfy a liability that has been assumed in the gas market manipulation litigation, then CenterPoint Energy, Houston Electric or CERC could incur liability and be responsible for satisfying the liability. CenterPoint Energy does not expect the ultimate outcome of the case against CES to have a material adverse effect on its financial condition, results of operations or cash flows.

Minnehaha Academy.  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, and the contractor company working in the school have been named in litigation arising out of this incident.  Additionally, CenterPoint Energy is cooperating with ongoing investigations conducted by the National Transportation Safety Board, the Minnesota Occupational Safety and Health Administration and the Minnesota Office of Pipeline Safety.  CenterPoint Energy’s general and excess liability insurance policies provide coverage for third party bodily injury and property damage claims. 

Environmental Matters

MGP Sites. CERC and its predecessors operated MGPs in the past.  With respect to certain Minnesota MGP sites, CERC has completed state-ordered remediation and continues state-ordered monitoring and water treatment. As of March 31,September 30, 2017, CERC had a recorded liability of $7 million for continued monitoring and any future remediation required by regulators in Minnesota. The estimated range of possible remediation costs for the sites for which CERC believes it may have responsibility was $5$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 Environmental Protection Agency and other regulators have investigated MGP sites that were owned or operated by CERC or may have been owned by one of its former affiliates. CenterPoint Energy does not expect the ultimate outcome of these matters to have a material adverse effect on the financial condition, results of operations or cash flows of either CenterPoint Energy or CERC.

Asbestos. Some facilities owned by CenterPoint Energy or its predecessors contain or have contained asbestos insulation and other asbestos-containing materials. CenterPoint Energy and its subsidiaries are from time to time named, along with numerous others, as defendants in lawsuits filed by a number of individuals who claim injury due to exposure to asbestos, and CenterPoint Energy anticipates that additional claims may be asserted in the future.  Although their ultimate outcome cannot be predicted at this time, CenterPoint Energy does not expect these matters, either individually or in the aggregate, to have a material adverse effect on CenterPoint Energy’s financial condition, results of operations or cash flows.

Other Environmental. From time to time, CenterPoint Energy identifies the presence of environmental contaminants during its operations or on property where its predecessor companies have conducted operations.  Other such sites involving contaminants may be identified in the future.  CenterPoint Energy has and expects to continue to remediate identified sites consistent with its legal obligations.  From time to time CenterPoint Energy has received notices from regulatory authorities or others regarding its status as a PRP in connection with sites found to require remediation due to the presence of environmental contaminants. In addition, CenterPoint Energy has been named from time to time as a defendant in litigation related to such sites. Although the ultimate outcome of such matters cannot be predicted at this time, CenterPoint Energy does not expect these matters, either individually or in the aggregate, to have a material adverse effect on CenterPoint Energy’s financial condition, results of operations or cash flows.

Other Proceedings

CenterPoint Energy is involved in other legal, environmental, tax and regulatory proceedings before various courts, regulatory commissions and governmental agencies regarding matters arising in the ordinary course of business. From time to time, CenterPoint Energy is also a defendant in legal proceedings with respect to claims brought by various plaintiffs against broad groups of participants in the energy industry. Some of these proceedings involve substantial amounts. CenterPoint Energy regularly analyzes current information and, as necessary, provides accruals for probable and reasonably estimable liabilities on the eventual disposition of these matters. CenterPoint Energy does not expect the disposition of these matters to have a material adverse effect on CenterPoint Energy’s financial condition, results of operations or cash flows.

Three months ended March 31,September 30, 2017 compared to three months ended March 31,September 30, 2016

We reported net income of $169 million ($0.39 per diluted share) for the three months ended September 30, 2017 compared to net income of $179 million ($0.41 per diluted share) for the three months ended September 30, 2016.

The decrease in net income of $10 million was primarily due to the following key factors:

a $40 million decrease in the gain on marketable securities included in Other Income, net shown above;

a $5 million decrease in operating income discussed below by segment;

a $5 million decrease in equity earnings from our investment in Enable, discussed further in Note 8 to our Interim Condensed Financial Statements; and

a $3 million decrease in miscellaneous other non-operating income included in Other Income, net shown above.


These decreases in net income were partially offset by the following:

a $36 million decrease in the loss on the underlying value of the indexed debt securities related to the ZENS included in Other Income, net shown above;

a $5 million decrease in interest expense related to lower outstanding balances of our Securitization Bonds; and

a $3 million decrease in interest expense due to lower weighted average interest rates on outstanding debt.

Nine months ended September 30, 2017 compared to nine months ended September 30, 2016

We reported net income of $192$496 million ($0.441.14 per diluted share) for the threenine months ended March 31,September 30, 2017 compared to net income of $154$331 million ($0.360.76 per diluted share) for the same period innine months ended September 30, 2016.

The increase in net income of $38$165 million was primarily due to the following key factors:

a $24$199 million decrease in the loss on indexed debt securities related to the ZENS included in Other Income, net shown above, resulting from decreased losses of $82 million in the underlying value of the indexed debt securities and a loss of $117 million from the Charter merger in 2016;

a $60 million increase in operating income discussed below by segment;

a $12$35 million increase in equity earnings from our investment in Enable, discussed further in Note 8 to our Interim Condensed Financial Statements;

a $9 million increase in cash distributions on Series A Preferred Units included in Other Income, net shown above;

a $9$21 million decrease in interest expense due to lower weighted average interest rates on outstanding debt;

a $4$14 million increase in cash distributions on Series A Preferred Units included in Other Income, net shown above; and

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

These increases in net income were partially offset by the following:

an $88 million increase in income tax expense due to higher net income;

an $83 million decrease in the gain on marketable securities included in Other Income, net shown above; and

a $1$5 million increasedecrease in miscellaneous other non-operating income included in Other Income, net shown above.

These increases in net income were partially offset by a $21 million increase in income tax expense due to higher net income.

Income Tax Expense

Our effective tax rate reported for both the three months ended March 31,September 30, 2017 and 2016was 37% compared to 35% for the same period in 2016. The higher effective tax rate for the three months ended September 30, 2017 was primarily due to the tax effects of receiving less nontaxable income in the period. The effective tax rate reported for the nine months ended September 30, 2017 was 36%. compared to 37% for the same period in 2016. We expect our annual effective tax rate for the fiscal year ending December 31, 2017 to be approximately 36%.

Three months ended March 31,September 30, 2017 compared to three months ended March 31,September 30, 2016

Our Electric Transmission & Distribution business segment reported operating income of $78$247 million for the three months ended March 31,September 30, 2017, consisting of $58$229 million from the TDU and $20$18 million related to the Bond Companies. For the three months ended March 31,September 30, 2016, operating income totaled $83$257 million, consisting of $59$234 million from the TDU and $24$23 million related to the Bond Companies.

TDU operating income decreased $1$5 million, primarily due to the following key factors:

lower usage of $12 million, largely due to a return to more normal weather in 2017;

lower equity return of $9 million, primarily related to the annual true-up of transition charges correcting for over-collections that occurred during 2016; and

lower miscellaneous revenues, including right-of-way, of $7 million.

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

rate increases of $12 million related to distribution capital investments;
lower operation and maintenance expenses of $4 million; and

customer growth of $9 million from the addition of over 46,000 new customers.

Nine months ended September 30, 2017 compared to nine months ended September 30, 2016

Our Electric Transmission & Distribution business segment reported operating income of $489 million for the nine months ended September 30, 2017, consisting of $431 million from the TDU and $58 million related to the Bond Companies. For the nine months ended September 30, 2016, operating income totaled $498 million, consisting of $428 million from the TDU and $70 million related to the Bond Companies.

TDU operating income increased $3 million, primarily due to the following key factors:

rate increases of $39 million related to distribution capital investments; and

customer growth of $26 million from the addition of over 46,000 new customers.

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

lower equity return of $22 million, primarily related to the annual true-up of transition charges correcting for over-collections that occurred during 2016;

higher depreciation and amortization expense, primarily because of ongoing additions to plant in service, and other taxes of $9$14 million;

lower equity return of $6 million, primarily related to the annual true-up of transition charges correcting for over-collections that occurred during the preceding 12 months;

lower usage of $4 million, primarily due to milder weather;$14 million;

lower miscellaneous revenues, including right-of-way, of $9 million;

higher operation and maintenance expenses of $2 million; and

higherincreased transmission costs billed by transmission providers of $18$47 million, which were partially offset by increasedhigher transmission-related revenues of $16$46 million.

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

rate increases of $16 million related to distribution capital investments; and

customer growth of $8 million from the addition of over 49,000 new customers.

Decreased depreciation and amortization expense of $5 million and operation and maintenance expense of $1 million were offset by a corresponding decrease in related revenues.

Natural Gas Distribution

Three months ended March 31,September 30, 2017 compared to three months ended March 31,September 30, 2016

Our Natural Gas Distribution business segment reported operating income of $19 million for the three months ended September 30, 2017 compared to $22 million for the three months ended September 30, 2016.

Operating income decreased $3 million as a result of the following key factors:

increased depreciation and amortization expense, primarily due to ongoing additions to plant-in-service, and other taxes of $6 million;

lower usage of $4 million, primarily due to the timing of a decoupling normalization adjustment; and

higher operation and maintenance expenses of $3 million.

These decreases were partially offset by the following:

rate relief increased $5 million, primarily from Texas jurisdictions of $2 million, Arkansas rate case filing of $1 million and Mississippi RRA of $1 million; and

customer growth of $2 million associated with the addition of approximately 38,000 new customers.

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


Nine months ended September 30, 2017 compared to nine months ended September 30, 2016

Our Natural Gas Distribution business segment reported operating income of $164$220 million for the threenine months ended March 31,September 30, 2017 compared to $160$202 million for the threenine months ended March 31,September 30, 2016.

Operating income increased $4$18 million as a result of the following key factors:

rate increases of $13$25 million, primarily from the Texas GRIP filingjurisdictions of $5$12 million, and the Arkansas rate case filing of $6$10 million and Mississippi RRA of $3 million;

Minnesota property tax refundlabor and benefits were favorable by $11 million resulting primarily from the recording of $9 million;a regulatory asset (and a corresponding reduction in expense) to recover $16 million of prior postretirement expenses in future rates established in the Texas Gulf rate order; and

customer growth of $2$3 million fromassociated with the addition of over 28,000approximately 38,000 new customers.

These increases were partially offset by the following:

increased depreciation and amortization expense, primarily due to ongoing additions to plant-in-service, and other taxes of $10 million;

higher operation and maintenance expenses of $9 million partially resulting from an adjustment associated with the Texas Gulf rate order of $4 million, which is timing related; and

lower usage of $15$7 million primarily due to milder weather effects, partially mitigated by decoupling and weather normalization adjustments and weather-related decoupling; and

higher depreciation and amortization expense of $4 million primarily due to ongoing additions to plant in service.adjustments.

Increased expenseoperation and maintenance expenses related to energy efficiency programs of $4$7 million and increased gross receipts taxes of $2 million were offset by a corresponding increaseincreases in the related revenues. Decreased expense related to rate case amortization of $1 million was offset by a corresponding decrease in the related revenues.

Operating income in the first nine months of 2017 also included $3 million of expenses related to the acquisition and integration of AEM. The remaining increase in operating income was primarily due to the increased throughput related to the acquisition of AEM in 2017.

Cash Provided by Operating Activities

Net cash provided by operating activities in the first threenine months of 2017 decreased $318$424 million compared to the same period infirst nine months of 2016 due to changes in working capital ($333301 million), partially offset by higherlower net income after adjusting for non-cash and non-operating items ($12 million) (primarily116 million; primarily depreciation and amortizationamortization) and deferred income taxes) and increaseddecreased cash from other non-current items ($37 million). The changes in working capital items in the first threenine months of 2017 primarily related to decreased cash provided by taxes receivable; margin deposits, net; net regulatory assets and liabilities; non-trading derivatives, net; and inventory; partially offset by increased

cash provided by net accounts receivable/payable; interest and taxes accrued; net other current assets and liabilities; inventory; and non-trading derivatives, net.fuel cost recovery.

Cash Used in Investing Activities

Net cash used in investing activities in the first threenine months of 2017 increased $101$153 million compared to the same period infirst nine months of 2016 primarily due to decreased cash received for the repayment of notes receivable from Enable ($363 million), decreased proceeds from the sale of marketable securities associated with the Charter merger ($178 million) and increased cash used for the AEM acquisitionacquisitions ($13230 million), which were partially offset by decreased cash used for the purchase of Series A Preferred Units ($363 million), decreased capital expenditures ($2053 million) and decreased restricted cash ($810 million). In 2017, we acquired AEM for $132 million in cash and, in 2016, we acquired Continuum for $102 million in cash.
 
Cash Used in Financing Activities

Net cash used in financing activities in the first threenine months of 2017 decreased $378$431 million compared to the same period infirst nine months of 2016 due to increased net proceeds from commercial paperlong-term debt ($338496 million), increased proceeds from the issuance of general mortgage bonds ($298 million), decreased short-term borrowings ($5 million) and decreased debt issuance costs ($2 million), which were offset by increased payments of long-term debt ($258 million), decreased distributions to ZENS holders ($178 million) and increased paymentshort-term borrowings ($10 million), which were partially offset by increased payments of commercial paper ($491 million), increased payments of common stock dividends ($514 million) and increased debt issuance costs ($4 million).

Future Sources and Uses of Cash

Our liquidity and capital requirements are affected primarily by our results of operations, capital expenditures, debt service requirements, tax payments, working capital needs and various regulatory actions. Our capital expenditures are expected to be used for investment in infrastructure for our electric transmission and distribution operations and our natural gas distribution operations.  These capital expenditures are anticipated to maintain reliability and safety as well as expand our systems through value-added projects. Our principal anticipated cash requirements for the remaining ninethree months of 2017 include the following:

capital expenditures of approximately $1.2 billion;$473 million;

maturing senior notes of $250 million;

scheduled principal payments on Securitization Bonds of $256$64 million;

restoration costs associated with Hurricane Harvey;

dividend payments on CenterPoint Energy, Inc. common stock; and

interest payments on debt.

We expect that borrowings under our credit facilities, proceeds from commercial paper and anticipated cash flows from operations and distributions on our investments in common and subordinated units and Series A Preferred Units from Enable will be sufficient to meet our anticipated cash needs for the remaining ninethree months of 2017. Discretionary financing or refinancing may result in the issuance of equity or debt securities in the capital markets or the arrangement of additional credit facilities. Issuances of equity or debt in the capital markets, funds raised in the commercial paper markets and additional credit facilities may not, however, be available to us on acceptable terms.
 
Off-Balance Sheet Arrangements

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

Regulatory Matters

Brazos Valley Connection Project

Construction began on the Brazos Valley Connection in February 2017, and is proceeding as scheduled. Houston Electric filed its updated capital costs estimates withexpects to complete construction and energize the PUCTBrazos Valley Connection in February 2017, projecting the first quarter of 2018, ahead of the original June 1, 2018 energization date.  Houston Electric continues to anticipate that the final capital costs of the project will be $310 million, in line withwithin the estimated range of approximately $270-$310 million in the PUCT’s original order. The actual capital costs of the

project will depend on final land acquisition costs, construction costs, and other factors. Houston Electric expects to complete construction and energize the Brazos Valley Connection by June 2018. Houston Electric is ableeligible to filecontinue making filings for the recovery of land acquisition costs through interim TCOS updates in advance of project completion.

Freeport Project

In April 2017, Houston Electric submitted a proposal to ERCOT requesting its endorsement of Houston Electric’s approximately $250 million transmission project in the Freeport, Texas area, which includes enhancements to two existing substations and the construction of a new 345 kv double-circuit transmission line. Capital expenditures for the project will be incremental to its previously disclosed five-year capital plan. Houston Electric anticipates a decision from ERCOT later in the fourth quarter of 2017, and if approved, will make the necessary filings with the PUCT.

PHMSA Matters

On December 14, 2016, PHMSA announced an interim final rule to impose industry-developed recommendations as enforceable safety standards for downhole (underground) equipment, including wells, wellbore tubing, and casing, at both interstate and intrastate underground natural gas storage facilities. Both CERC and Enable own and operate underground storage facilities that are subject to this rule’s provisions, which include procedures and practices for operations, maintenance, threat identification, monitoring, assessment, site security, emergency response and preparedness, training and recordkeeping. This rule went into effect on January 18, 2017, with an announced compliance deadline of January 18, 2018. PHMSA determined, however, that it will not issue enforcement citations to any operators for violations of provisions of the interim final rule that had previously been non-mandatory provisions of American Petroleum Institute Recommended Practices 1170 and 1171 until one year after PHMSA issues a final rule, which it expects to publish in January of 2018. On October 19, 2017, PHMSA formally reopened the comment period on the interim final rule in response to a petition for reconsideration. This matter remains ongoing and subject to future PHMSA determinations. CERC and Enable will continue to monitor developments and assess the potential impact of any modifications to this rule.

Rate Change Applications

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

Other Matters

Credit Facilities

Our revolving credit facilities may be drawn on by the companies from time to time to provide funds used for general corporate purposes, including to backstop the companies’ commercial paper programs. The facilities may also be utilized to obtain letters of credit. For further details related to our revolving credit facilities and the 2017 amendments, please see Note 11 to our Interim Condensed Financial Statements.

For further details related to our revolving credit facilities, please see Note 11 to our Interim Condensed Financial Statements.

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

Debt Financing Transactions

In January 2017, Houston Electric issued $300 million aggregate principal amount of general mortgage bonds. In February 2017, CenterPoint Energy retired $250 million aggregate principal amount of its 5.95% senior notes at their maturity. In August 2017, CenterPoint Energy issued $500 million aggregate principal amount of unsecured senior notes. In August 2017, CERC Corp. issued $300 million aggregate principal amount of unsecured senior notes. For further information about our 2017 debt transactions, see Note 11 to our Interim Condensed Financial Statements.

Securities Registered with the SEC

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

Temporary Investments

As of April 21,October 26, 2017, we had no temporary external investments.


Money Pool

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

Impact on Liquidity of a Downgrade in Credit Ratings

The interest on borrowings under our credit facilities is based on our credit rating. On August 4, 2017, S&P revised its rating outlooks on senior debt of CenterPoint Energy, Houston Electric and CERC Corp. to positive from developing and affirmed its ratings. On September 24, 2017, Fitch upgraded Houston Electric’s senior secured debt rating to A+ and maintained its rating outlook of stable. In addition, Fitch revised its rating outlooks on senior debt of CenterPoint Energy and CERC Corp. to positive from stable and affirmed its ratings.

As of April 21,October 26, 2017, Moody’s, S&P and Fitch had assigned the following credit ratings to senior debt of CenterPoint Energy and certain subsidiaries: 
  Moody’s S&P Fitch
Company/Instrument Rating Outlook (1) Rating Outlook (2) Rating Outlook (3)

 Baa2 Stable A- DevelopingPositive BBB StablePositive
   
(1)A Moody’s rating outlook is an opinion regarding the likely direction of an issuer’s rating over the medium term.

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

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

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

A decline in credit ratings could increase borrowing costs under our revolving credit facilities. If our credit ratings or those of Houston Electric or CERC Corp. had been downgraded one notch by each of the three principal credit rating agencies from the ratings that existed at March 31,as of September 30, 2017, the impact on the borrowing costs under the three revolving credit facilities would have been immaterial. A decline in credit ratings would also increase the interest rate on long-term debt to be issued in the capital markets and could negatively impact our ability to complete capital market transactions and to access the commercial paper market. Additionally, a decline in credit ratings could increase cash collateral requirements and reduce earnings of our Natural Gas Distribution and Energy Services business segments.

CES, a wholly-owned subsidiary of CERC Corp. operating in our Energy Services business segment, provides natural gas sales and services primarily to commercial and industrial customers and electric and natural gas utilities throughout the 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 or settled-to-market by CES. As of March 31,September 30, 2017, the amounts posted as collateral and settled-to-market aggregated approximately $29$35 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 March 31,September 30, 2017, unsecured credit limits extended to CES by counterparties aggregated $367$358 million, and $1 million of such amount was utilized.


Pipeline tariffs and contracts typically provide that if the credit ratings of a shipper or the shipper’s guarantor drop below a threshold level, which is generally investment grade ratings from both Moody’s and S&P, cash or other collateral may be demanded from the shipper in an amount equal to the sum of three months’ charges for pipeline services plus the unrecouped cost of any lateral built for such shipper. If the credit ratings of CERC Corp. decline below the applicable threshold levels, CERC Corp. might need to provide cash or other collateral of as much as $180$197 million as of March 31,September 30, 2017. The amount of collateral will depend on seasonal variations in transportation levels.

ZENS and Securities Related to ZENS

If our creditworthiness were to drop such that ZENS holders thought our liquidity was adversely affected or the market for the ZENS were to become illiquid, some ZENS holders might decide to exchange their ZENS for cash. Funds for the payment of cash upon exchange could be obtained from the sale of the shares of TW Securities that we own or from other sources. We own shares of TW Securities equal to approximately 100% of the reference shares used to calculate our obligation to the holders of the ZENS. ZENS exchanges result in a cash outflow because tax deferrals related to the ZENS and TW Securities shares would typically cease when ZENS are exchanged or otherwise retired and TW Securities shares are sold. The ultimate tax liability related to the ZENS continues to increase by the amount of the tax benefit realized each year, and there could be a significant cash outflow when the taxes are paid as a result of the retirement of the ZENS. If all ZENS had been exchanged for cash on March 31,September 30, 2017, deferred taxes of approximately $461$472 million would have been payable in 2017. If all the TW Securities had been sold on March 31,September 30, 2017, capital gains taxes of approximately $310$331 million would have been payable in 2017.

For additional information about ZENS, see Note 10 to our Interim Condensed Financial Statements.

Cross Defaults

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

Possible Acquisitions, Divestitures and Joint Ventures

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

In February 2016, we announced that we were evaluating strategic alternatives for our investment in Enable, including a sale or spin-off qualifying under Section 355 of the U.S. Internal Revenue Code, andCode. We have determined that we continuewill no longer pursue a spin option. Should the sale option not be viable, we intend to evaluatereduce our alternatives, including retaining our investment.ownership in Enable over time through a sale of the common units we hold in the public equity markets, subject to market conditions. There can be no assurances that these evaluations will result in any specific action, and we do not intend to disclose further developments on these initiatives unless and until our board of directors approves a specific action or as otherwise required.

Enable Midstream Partners

We receive quarterly cash distributions from Enable on its common and subordinated units we own. We also receive quarterly cash distributions from Enable on theand Series A Preferred Units we own. A reduction in the cash distributions we receive from Enable could significantly impact our liquidity. For additional information about cash distributions from Enable, see Notes 8 and 16 to our Interim Condensed Financial Statements.

Hedging of Interest Expense for Future Debt Issuances

During the first quarterthree quarters of 2017, we entered into forward interest rate agreements to hedge, in part, volatility in the U.S. treasury rates by reducing variability in cash flows related to interest payments. For further information, see Note 6(a) to our Interim Condensed Financial Statements.


Weather Hedge

We have historically entered into partial weather hedges for certain NGD jurisdictions and Houston Electric’s service territory to mitigate the impact of fluctuations from normal weather. We remain exposed to some weather risk as a result of the partial hedges. For more information about our weather hedges, see Note 6(a) to our Interim Condensed Financial Statements.

Other Factors that Could Affect Cash Requirements

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

cash collateral requirements that could exist in connection with certain contracts, including our weather hedging arrangements, and gas purchases, gas price and gas storage activities of our Natural Gas Distribution and Energy Services business segments;
 
acceleration of payment dates on certain gas supply contracts, under certain circumstances, as a result of increased gas prices and concentration of natural gas suppliers;
 
increased costs related to the acquisition of natural gas;
 
increases in interest expense in connection with debt refinancings and borrowings under credit facilities;
 
various legislative or regulatory actions;
 
incremental collateral, if any, that may be required due to regulation of derivatives;
 
the ability of GenOn and its subsidiaries, currently the subject of bankruptcy proceedings, to satisfy their obligations in respect of GenOn’s indemnity obligations to us and our subsidiaries;

the ability of REPs, including REP affiliates of NRG and Vistra Energy Future HoldingsCorp., formerly known as TCEH Corp., to satisfy their obligations to us and our subsidiaries;

slower customer payments and increased write-offs of receivables due to higher gas prices or changing economic conditions;
 
the outcome of litigation brought by or against us;
 
contributions to pension and postretirement benefit plans;
 
restoration costs and revenue losses resulting from future natural disasters such as hurricanes and the timing of recovery of such restoration costs; and

various other risks identified in “Risk Factors” in Item 1A of Part I of our 2016 Form 10-K.

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

Houston Electric has contractually agreed that it will not issue additional first mortgage bonds, subject to certain exceptions. For information about the total debt to capitalization financial covenants in our revolving credit facilities, see Note 11 to our Interim Condensed Financial Statements.

Item 3.QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest Rate Risk

As of March 31,September 30, 2017, we had outstanding long-term debt, lease obligations and obligations under our ZENS that subject us to the risk of loss associated with movements in market interest rates.

Our floating rate obligations aggregated $1.6 billion$976 million and $1.4 billion as of March 31,September 30, 2017 and December 31, 2016, respectively. If the floating interest rates were to increase by 10% from March 31,September 30, 2017 rates, our combined interest expense would increase by approximately $2$1.4 million annually.

As of March 31,September 30, 2017 and December 31, 2016, we had outstanding fixed-rate debt (excluding indexed debt securities) aggregating $7.0$7.6 billion and $7.1 billion, respectively, in principal amount and having a fair value of $7.48.1 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 $208$223 million if interest rates were to decline by 10% from levels at March 31,September 30, 2017. In general, such an increase in fair value would impact earnings and cash flows only if we were to reacquire all or a portion of these instruments in the open market prior to their maturity.

The ZENS obligation is bifurcated into a debt component and a derivative component. The debt component of $116120 million as of March 31,September 30, 2017 was a fixed-rate obligation and, therefore, did not expose us to the risk of loss in earnings due to changes in market interest rates. However, the fair value of the debt component would increase by approximately $18 million if interest rates were to decline by 10% from levels at March 31,September 30, 2017. Changes in the fair value of the derivative component, a $727$776 million recorded liability at March 31,September 30, 2017, 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 March 31,September 30, 2017 levels, the fair value of the derivative component liability would increase by approximately $5 million, which would be recorded as an unrealized loss in our Condensed Statements of Consolidated Income.

Equity Market Value Risk

We are exposed to equity market value risk through our ownership of 7.1 million shares of TW Common, 0.9 million shares of Time Common and 0.9 million shares of Charter Common, which we hold to facilitate our ability to meet our obligations under the ZENS. A decrease of 10% from the March 31,September 30, 2017 aggregate market value of these shares would result in a net loss of approximately $21 million, which would be recorded as an unrealized loss in our Condensed Statements of Consolidated Income.

Commodity Price Risk From Non-Trading Activities

We use derivative instruments as economic hedges to offset the commodity price exposure inherent in our businesses. The 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 March 31,September 30, 2017, the recorded fair value of our non-trading energy derivatives was a net asset of $62$80 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 approximately $2$3 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-marketmark 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-valuefair value hedges.

Item 4.CONTROLS AND PROCEDURES

In accordance with Exchange Act Rules 13a-15 and 15d-15, we carried out an evaluation, under the supervision and with the participation of management, including our principal executive officer and principal financial officer, of the effectiveness of our disclosure controls and procedures as of the end of the period covered by this report. Based on that evaluation, our principal executive officer and principal financial officer concluded that our disclosure controls and procedures were effective as of March 31,September 30, 2017 to provide assurance that information required to be disclosed in our reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and such information

such information is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding disclosure.

There has been no change in our internal controls over financial reporting that occurred during the three months ended March 31,September 30, 2017 that has materially affected, or is reasonably likely to materially affect, our internal controls over financial reporting.
