CENTERPOINT ENERGY, INC. AND SUBSIDIARIES

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(1)       Background and Basis of Presentation

General. Included in this Quarterly Report on Form 10-Q (Form 10-Q) of CenterPoint Energy, Inc. are the condensed consolidated interim financial statements and notes (Interim Condensed Financial Statements) of CenterPoint Energy, Inc. and its subsidiaries (collectively, CenterPoint Energy). The Interim Condensed Financial Statements are unaudited, omit certain financial statement disclosures and should be read with the Annual Report on Form 10-K of CenterPoint Energy for the year ended December 31, 2010 (CenterPoint Energy 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 facilities, natural gas distribution facilities, interstate pipelines and natural gas gathering, processing and treating facilities. As of March 31, 2011, CenterPoint Energy’s indirect wholly owned subsidiaries included:

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

• CenterPoint Energy Resources Corp. (CERC Corp. and, together with its subsidiaries, CERC), which owns and operates natural gas distribution systems. Subsidiaries of CERC Corp. own interstate natural gas pipelines and gas gathering systems and provide various ancillary services. A wholly owned subsidiary of CERC Corp. offers variable and fixed-price physical natural gas supplies primarily to commercial and industrial customers and electric and gas utilities.

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 14.

(2)       New Accounting Pronouncements

In January 2010, the Financial Accounting Standards Board issued new accounting guidance to require additional fair value related disclosures. It also clarified existing fair value disclosure guidance about the level of disaggregation, inputs and valuation techniques. This new guidance was effective for the first reporting period beginning after December 15, 2009 except for certain disclosure requirements effective for the first reporting period beginning after December 15, 2010. CenterPoint Energy's adoption of this new guidance did not have a material impact on its financial position, results of operations or cash flows. See Note 6 for the required disclosures.

Management believes the impact of 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)       Employee Benefit Plans

CenterPoint Energy’s net periodic cost includes the following components relating to pension and postretirement benefits:

	Three Months Ended March 31,
	2010						2011
	Pension Benefits (1)			Postretirement Benefits			Pension Benefits (1)			Postretirement Benefits
	(in millions)
Service cost	$	8		$	—		$	8		$	—
Interest cost		25			6			25			6
Expected return on plan assets		(27	)		(2	)		(29	)		(2	)
Amortization of prior service credit		1			1			1			1
Amortization of net loss		15			—			14			—
Amortization of transition obligation		—			2			—			2
Net periodic cost	$	22		$	7		$	19		$	7

(1) Net periodic cost in these tables is before considering amounts subject to overhead allocations for capital expenditure projects or for amounts subject to deferral for regulatory purposes.  CenterPoint Houston’s actuarially determined pension expense for 2011 in excess of the 2007 base year amount is being deferred for rate making purposes. CenterPoint Houston deferred as a regulatory asset $6 million in pension expense during both the three months ended March 31, 2010 and 2011.

CenterPoint Energy expects to contribute approximately $64 million to its pension plans in 2011, of which approximately $3 million was contributed during the three months ended March 31, 2011.

CenterPoint Energy expects to contribute approximately $18 million to its postretirement benefits plan in 2011, of which approximately $6 million was contributed during the three months ended March 31, 2011.

(4)       Regulatory Matters

(a) Recovery of True-Up Balance

In March 2004, CenterPoint Houston filed its true-up application with the Public Utility Commission of Texas (Texas Utility Commission), requesting recovery of $3.7 billion, excluding interest, as allowed under the Texas Electric Choice Plan (Texas electric restructuring law). In December 2004, the Texas Utility Commission issued its final order (True-Up Order) allowing CenterPoint Houston to recover a true-up balance of approximately $2.3 billion, which included interest through August 31, 2004, and provided for adjustment of the amount to be recovered to include interest on the balance until recovery, along with the principal portion of additional excess mitigation credits (EMCs) returned to customers after August 31, 2004 and certain other adjustments.  To reflect the impact of the True-Up Order, in 2004 and 2005, CenterPoint Energy recorded a net after-tax extraordinary loss of $947 million.

Various parties, including CenterPoint Houston, appealed the True-Up Order.  These appeals were heard first by a district court in Travis County, Texas, then by the Texas Third Court of Appeals and finally by the Texas Supreme Court.  On March 18, 2011, the Texas Supreme Court issued a unanimous ruling on such appeals in which it affirmed in part and reversed in part the decision of the Texas Utility Commission and remanded the matter to the Texas Utility Commission for further proceedings. The impact of the Texas Supreme Court’s decision regarding the matters on appeal is summarized as follows:

• The method used by the Texas Utility Commission to calculate the market value of CenterPoint Energy’s former generating assets was overturned. In its decision, the Texas Utility Commission had rejected the partial stock valuation method CenterPoint Houston utilized to establish the market value of the generating assets, and the Texas Utility Commission had fashioned its own valuation. The Texas Supreme Court ruled that the Texas Utility Commission had no authority to craft an alternative valuation methodology but instead should have valued the generating assets at the value established when CenterPoint Energy later sold its Texas Genco subsidiary. This portion of the decision requires that the valuation question be remanded to the Texas Utility Commission for a determination. CenterPoint Energy currently estimates that

6

application of the sale of assets methodology would reduce stranded costs by approximately $252 million, less selling costs, with the amount ultimately determined (plus interest) subtracted from the amounts eligible for recovery in the remand proceeding. This portion of the decision is unfavorable to CenterPoint Energy.

• The Texas Utility Commission’s order denying recovery of approximately $440 million in capacity auction true-up amounts was reversed. This portion of the decision is favorable to CenterPoint Energy. These sums plus interest are eligible for recovery in the remand proceeding.

• The Texas Utility Commission’s refusal to include approximately $378 million related to depreciation in the calculation of stranded costs was reversed. This portion of the decision is favorable to CenterPoint Energy. These sums plus interest are eligible for recovery in the remand proceeding.

• The Texas Utility Commission’s order allowing recovery of excess mitigation credits (EMCs) that CenterPoint Energy had been ordered to pay its former affiliate was upheld. This portion of the decision is favorable to CenterPoint Energy. These sums have already been recovered and will not be addressed in the remand proceeding.

• The Texas Utility Commission decisions allowing recovery of construction work in progress balances and interest on the capacity auction true-up amounts were upheld. These decisions are favorable to CenterPoint Energy. These sums have already been recovered and will not be addressed in the remand proceeding.

The Texas Supreme Court did not address the court of appeals’ decision allowing CenterPoint Houston to recover approximately $210 million representing the interest component of the EMCs. This decision, which was favorable to CenterPoint Energy, was not appealed to the Texas Supreme Court. These sums plus interest are eligible for recovery in the remand proceeding.

Among the issues to be taken up by the Texas Utility Commission on the remand from the Texas Supreme Court is the proper regulatory treatment of certain deferred tax benefits.  In the True-Up Order, the Texas Utility Commission reduced CenterPoint Houston’s true-up balance by approximately $146 million, which was included in the extraordinary loss discussed above, to reflect the present value of certain deferred tax benefits associated with its former electric generation assets. CenterPoint Energy believes that the Texas Utility Commission based its order on proposed regulations issued by the Internal Revenue Service (IRS) in March 2003 that would have allowed utilities owning assets that were deregulated before March 4, 2003 to make a retroactive election to pass the benefits of Accumulated Deferred Investment Tax Credits (ADITC) and Excess Deferred Federal Income Taxes (EDFIT) back to customers. However, the IRS subsequently withdrew those proposed normalization regulations and, in March 2008, adopted final regulations that would not permit utilities like CenterPoint Houston to pass the tax benefits back to customers without creating normalization violations. In addition, CenterPoint Energy received a Private Letter Ruling (PLR) from the IRS in August 2007, prior to adoption of the final regulations, that confirmed that the Texas Utility Commission’s order reducing CenterPoint Houston’s stranded cost recovery by $146 million for ADITC and EDFIT would cause normalization violations with respect to the ADITC and EDFIT. The Texas Utility Commission thereafter requested that this issue be remanded to that commission for further consideration, and that request was granted by the court of appeals.  CenterPoint Houston plans to seek to recover $146 million plus interest related to this issue in the remand proceedings.

If the Texas Utility Commission’s order relating to the ADITC reduction is not reversed or otherwise modified on remand so as to eliminate the normalization violation, the IRS could require CenterPoint Energy to pay an amount equal to CenterPoint Houston’s unamortized ADITC balance as of the date that the normalization violation is deemed to have occurred. In addition, the IRS could deny CenterPoint Houston the ability to elect accelerated tax depreciation benefits beginning in the taxable year that the normalization violation is deemed to have occurred. Such treatment, if required by the IRS, could have a material adverse impact on CenterPoint Energy’s results of operations, financial condition and cash flows.

A number of parties have asked the Texas Supreme Court to reconsider its decision.  The court has 180 days from the filing of a motion for rehearing to rule on that request.  The remand to the Texas Utility Commission for further proceedings will not occur until after the court has acted on the motions for rehearing.  There is no statutory deadline by which the Texas Utility Commission must act once the case has been remanded to it; but, in accordance with the rules of the Texas Utility Commission, interest on the unsecuritized true-up balance will continue to accrue until such time as the unrecovered true-up balance is securitized or is otherwise reflected in rates.

7

The Texas electric restructuring law allowed the amounts awarded to CenterPoint Houston in the Texas Utility Commission’s True-Up Order to be recovered either through securitization or through implementation of a competition transition charge (CTC) or both. Pursuant to a financing order issued by the Texas Utility Commission in March 2005, in December 2005, a new special purpose subsidiary of CenterPoint Houston issued $1.85 billion in transition bonds with interest rates ranging from 4.84% to 5.30% and final maturity dates ranging from February 2011 to August 2020. Through issuance of the transition bonds, CenterPoint Houston recovered approximately $1.7 billion of the true-up balance determined in the True-Up Order plus interest through the date on which the bonds were issued.

In July 2005, CenterPoint Houston received an order from the Texas Utility Commission allowing it to implement a CTC designed to collect the remaining $596 million from the True-Up Order over 14 years plus interest at an annual rate of 11.075% (CTC Order). The CTC Order authorized CenterPoint Houston to impose a charge on REPs to recover the portion of the true-up balance not recovered through a financing order. The CTC Order also allowed CenterPoint Houston to collect approximately $24 million of rate case expenses over three years without a return through a separate tariff rider (Rider RCE). CenterPoint Houston implemented the CTC and Rider RCE effective September 13, 2005 and began recovering approximately $620 million. The return on the CTC portion of the true-up balance was included in CenterPoint Houston’s tariff-based revenues beginning September 13, 2005. Effective August 1, 2006, the interest rate on the unrecovered true-up balance was reduced from 11.075% to 8.06% pursuant to a revised rule adopted by the Texas Utility Commission in June 2006. Recovery of rate case expenses under Rider RCE was completed in September 2008.

During the 2007 legislative session, the Texas legislature amended statutes prescribing the types of true-up balances that can be securitized by utilities and authorized the issuance of transition bonds to recover the balance of the CTC. In February 2008, pursuant to the financing order, a new special purpose subsidiary of CenterPoint Houston issued approximately $488 million of transition bonds in two tranches with interest rates of 4.192% and 5.234% and final maturity dates of February 2020 and February 2023, respectively. Contemporaneously with the issuance of those bonds, the CTC was terminated and a transition charge was implemented.

As of March 31, 2011, CenterPoint Energy has not recognized an allowed equity return of $175 million on CenterPoint Houston’s true-up balance because such return will be recognized as it is recovered in rates. During both the three months ended March 31, 2010 and 2011, CenterPoint Houston recognized approximately $3 million of the allowed equity return.

If the Texas Supreme Court’s decision is not modified as a result of the motions for rehearing and becomes final, CenterPoint Houston expects to seek recovery of approximately $1.85 billion, which includes interest through September 30, 2011. Interest on the true up balance would continue to accrue at approximately 8% if securitization bonds are not issued on or before September 30, 2011.  CenterPoint Energy expects to record the effects of the Texas Supreme Court’s decision once a final resolution of these matters is reached.

The final resolution of the true-up proceedings and the ultimate amount and timing of recovery of the additional amounts authorized will depend upon the outcome of requests to the Texas Supreme Court for rehearing, future actions by the Texas Utility Commission in response to rulings by the Texas Supreme Court and the court of appeals, and any future appeals thereof.  CenterPoint Houston intends to file an application with the Texas Utility Commission for approval of a financing order authorizing the issuance of transition bonds by one or more new special purpose subsidiaries of CenterPoint Houston to securitize the recoverable amounts and certain qualified costs.

(b) Rate Proceedings

CenterPoint Houston

 June 2010 Rate Proceeding. As required under a final order in its 2006 rate proceeding, in June 2010 CenterPoint Houston filed an application to change rates with the Texas Utility Commission and the cities in its service area.  The filing included cost data and other information supporting an annual increase of $106 million for delivery charges to the REPs that sell electricity to end-use customers in CenterPoint Houston’s service territory

8

partially offset by a reduction of other utility revenues, resulting in a $92 million requested annual revenue increase. The rate filing package also supported an annual increase of $18 million for wholesale transmission customers.

In the filing, CenterPoint Houston also requested reconciliation of its Advanced Metering System (AMS) costs incurred as of March 31, 2010, and revision of the estimated costs to complete the AMS project in order to reflect $150 million in funds from the $200 million Department of Energy (DOE) stimulus grant awarded to CenterPoint Houston and updated cost information. The reconciliation plan also requested that the duration of the residential AMS surcharge be shortened by six years from the original 12-year plan.

CenterPoint Houston’s filing sought a return on equity of 11.25% and proposed that rates be based on a capital structure of 50% equity and 50% long-term debt.

Hearings concerning the rate filing concluded in October 2010, and a Proposal for Decision was issued by the presiding Administrative Law Judges.  On February 3, 2011 the Texas Utility Commission voted on the various contested issues presented by the rate filing, and on April 29, 2011, the Texas Utility Commission voted to approve a draft final order conforming to its prior deliberations, subject to certain administrative revisions. CenterPoint Houston expects that order to be issued in the next several weeks but that revised rates based on that order would not be implemented before the third quarter.  The final order will be subject to revision based on motions for rehearing filed by the parties to the proceeding and could be appealed to the Texas courts.

The order of the Texas Utility Commission will provide for a base rate increase for CenterPoint Houston of approximately $14.7 million per year for delivery charges to the REPs and a decrease to charges to wholesale transmission customers of $12.3 million per year.  Further, the order will adopt a mechanism to track amounts for uncertain tax positions and provide for ultimate recovery of those costs.

The order will be based on an authorized return on equity for CenterPoint Houston of 10%, a cost of debt of ­6.74­%, a capital structure comprised of 55% debt and 45% common equity, and an overall rate of return of 8.21%.  The decision also will implement CenterPoint Houston’s request to reconcile costs incurred for the AMS project and to shorten the period for collecting the AMS surcharge from twelve to six years for residential customers in order to reflect the funds received from the DOE.

Based on CenterPoint Houston’s understanding of the Texas Utility Commission’s draft order, CenterPoint Houston anticipates that normalized annual operating income will be reduced by approximately $30 million from 2010 levels as a result of the Texas Utility Commission’s decision.

Other.  In May 2009, CenterPoint Houston filed an application at the Texas Utility Commission seeking approval of certain estimated 2010 energy efficiency program costs, an energy efficiency performance bonus for 2008 programs, and carrying costs totaling approximately $10 million. The application sought to begin recovery of these costs through a surcharge effective July 1, 2010. In October 2009, the Texas Utility Commission issued its order approving recovery of the 2010 energy efficiency program costs and a partial performance bonus of approximately $8 million, plus carrying costs, but disallowed a recovery of a performance bonus of $2 million on approximately $10 million in 2008 energy efficiency costs expended pursuant to the terms of a settlement agreement in a prior rate case.  CenterPoint Houston began collecting the approved amounts in July 2010. CenterPoint Houston appealed the denial of the full 2008 performance bonus to the 98th district court in Travis County, Texas. In October 2010, the district court upheld the Texas Utility Commission’s decision.  In February 2011, CenterPoint Houston appealed the district court’s judgment to the Texas Third Court of Appeals at Austin, Texas, where the case remains pending.

In April 2010, CenterPoint Houston filed an application with the Texas Utility Commission seeking approval of the recovery of $14.4 million related to estimated 2011 energy efficiency programs, an energy efficiency performance bonus for 2009 programs, and recovery of revenue losses related to the implementation of the 2009 energy efficiency program. The application sought to begin recovery of these costs through a surcharge beginning in January 2011.  In November 2010, the Texas Utility Commission issued its order approving recovery of approximately $11 million of the 2011 energy efficiency program costs and a performance bonus, but disallowed a recovery of a performance bonus of $2 million on the 2009 energy efficiency costs expended pursuant to the terms of the settlement agreement referenced above. The Texas Utility Commission further concluded that it does not have statutory authority to permit recovery of the approximately $1.4 million in lost revenue associated with 2009 energy efficiency programs. CenterPoint Houston began collecting the approved amounts in January 2011, but has appealed

9

the denial of the full 2009 performance bonus and lost revenue to the 201st district court in Travis County, Texas, where the case remains pending.

In April 2011, CenterPoint Houston filed an application with the Texas Utility Commission seeking approval of the recovery of a total of approximately $44.3 million in 2012 consisting of: (1) estimated 2012 energy efficiency program costs of approximately $35.8 million; (2) an energy efficiency performance bonus based on CenterPoint Houston’s 2010 program achievements of approximately $5.8 million; (3) the amount of lost revenues due to verified and reported 2010 energy savings of approximately $2.2 million; and (4) approximately $0.5 million for under-recovery of 2010 program costs.  The proposed adjustments are expected to take effect with the commencement of CenterPoint Houston’s January 2012 billing month.

Gas Operations

Texas. In March 2008, the natural gas distribution business of CERC (Gas Operations) filed a request to change its rates with the Railroad Commission of Texas (Railroad Commission) and the 47 cities in its Texas Coast service territory, an area consisting of approximately 230,000 customers in cities and communities on the outskirts of Houston. In 2008, the Railroad Commission approved the implementation of rates increasing annual revenues by approximately $3.5 million.  The approved rates were contested by a coalition of nine cities in an appeal to the 353rd district court in Travis County, Texas. In January 2010, that court reversed the Railroad Commission’s order in part and remanded the matter to the Railroad Commission.  In its final judgment, the court ruled that the Railroad Commission lacked authority to impose the approved cost of service adjustment mechanism in both those nine cities and in those areas in which the Railroad Commission has original jurisdiction.  The Railroad Commission and Gas Operations have appealed the court’s ruling on the cost of service adjustment mechanism to the Texas Third Court of Appeals at Austin, Texas. Oral arguments were held in February 2011. CenterPoint Energy does not expect the outcome of this matter to have a material adverse impact on its financial condition, results of operations or cash flows. The cost of service adjustment was initially effective for three successive years ending in calendar year 2010, but would automatically renew for successive three-year periods unless Gas Operations or the regulatory authority having original jurisdiction gave written notice to discontinue the adjustment mechanism by February 1, 2011. Certain cities that agreed to the initial implementation notified Gas Operations by February 1, 2011 of their desire to discontinue the adjustment mechanism. Gas Operations will continue the cost of service adjustments for the remaining areas.

In July 2009, Gas Operations filed a request to change its rates with the Railroad Commission and the 29 cities in its Houston service territory, consisting of approximately 940,000 customers in and around Houston. The request sought to establish uniform rates, charges and terms and conditions of service for the cities and environs of the Houston service territory. As finally submitted to the Railroad Commission and the cities, the proposed new rates would have resulted in an overall increase in annual revenue of $20.4 million, excluding carrying costs of approximately $2 million on its gas inventory, and would be subject to an annual cost of service adjustment. In January 2010, Gas Operations withdrew its request for an annual cost of service adjustment mechanism due to the uncertainty caused by the court’s ruling in the above-mentioned Texas Coast appeal. In February 2010, the Railroad Commission issued its decision authorizing a revenue increase of $5.1 million annually, reflecting reduced depreciation rates as well as adjustments to pension and other employee benefits, accumulated deferred income taxes and other items. The Railroad Commission also approved a surcharge of $0.9 million per year to recover costs associated with damage caused by Hurricane Ike over three years.  These rates went into effect in March 2010. Gas Operations and other parties are seeking judicial review of the Railroad Commission’s decision in the 261st District Court in Travis County, Texas.

In December 2010, Gas Operations filed a request to change its rates with the Railroad Commission and the 66 cities in its South Texas service territory, consisting of approximately 137,000 customers. As finally submitted to the Railroad Commission and the cities, the proposed new rates would have resulted in an overall increase in annual revenue of approximately $6.1 million.  The parties reached a settlement resulting in increased revenues of $4.6 million, which was approved by the Railroad Commission in April 2011.  Gas Operations expects to implement the new rates effective May 2011.

Other. Gas Operations has various periodic rate adjustment mechanisms available for use in certain of the jurisdictions in which it operates. In March 2011, Gas Operations made its Annual Billing Determinant Adjustment filing with the Arkansas Public Service Commission (APSC) requesting an annual increase in base rates of $5.9 million to collect the amounts accrued in 2010 for recovery of declines in revenues as a result of lower volumes and number of customers.  The request is subject to approval by the APSC and the increase is expected to become effective in the second quarter of 2011.  Additionally, in March 2011, Gas Operations made annual rate filings in Oklahoma and for certain portions of Texas that, subject to approval by the applicable regulatory bodies, would result in increased annual base rates of $1.3 million.

(5)       Derivative Instruments

CenterPoint Energy is exposed to various market risks. These risks arise from transactions entered into in the normal course of business.  CenterPoint Energy utilizes derivative instruments such as physical forward contracts, swaps and options to mitigate the impact of changes in commodity prices and weather on its operating results and cash flows. Such derivatives are recognized in CenterPoint Energy’s 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 all commodity price, weather and credit risk activities, including CenterPoint Energy’s marketing, risk management services and hedging activities. The committee’s duties are to establish CenterPoint Energy’s commodity risk policies, allocate board-approved commercial risk limits, approve the use of new products and commodities, monitor positions and ensure compliance with CenterPoint Energy’s risk management policies and procedures and limits established by CenterPoint Energy’s board of directors.

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

(a) Non-Trading Activities

Derivative Instruments. CenterPoint Energy enters into certain derivative instruments to manage physical commodity price risks and does not engage in proprietary or speculative commodity trading.  These financial instruments do not qualify or are not designated as cash flow or fair value hedges.

During the three months ended March 31, 2010, CenterPoint Energy recorded increased natural gas revenues from unrealized net gains of $30 million and increased natural gas expense from unrealized net losses of $27 million, resulting in a net unrealized gain of $3 million.  During the three months ended March 31, 2011, CenterPoint Energy recorded decreased natural gas revenues from unrealized net losses of $17 million and decreased natural gas expense from unrealized net gains of $15 million, resulting in a net unrealized loss of $2 million.

Weather Hedges. CenterPoint Energy has weather normalization or other rate mechanisms that mitigate the impact of weather on its gas operations in Arkansas, Louisiana, Oklahoma and a portion of Texas. The remaining Gas Operations jurisdictions do not have such mechanisms. As a result, fluctuations from normal weather may have a significant positive or negative effect on Gas Operations’ results in the remaining jurisdictions and in CenterPoint Houston’s service territory.

CenterPoint Energy enters into heating-degree day swaps to mitigate the effect of fluctuations from normal weather on its results of operations and cash flows for the winter heating season.  The swaps are based on ten-year normal weather. During the three months ended March 31, 2010 and 2011, CenterPoint Energy recognized losses of $7 million and $5 million, respectively related to these swaps. The losses were substantially offset by increased revenues due to colder than normal weather. Weather hedge losses are included in revenues in the Condensed Statements of Consolidated Income.

Total		$	80	$	411

(1) Natural gas contracts are subject to master netting arrangements and are presented on a net basis in the Condensed Consolidated Balance Sheets. This netting causes derivative assets (liabilities) to be ultimately presented net in a liability (asset) account within the Condensed Consolidated Balance Sheets.

(2) The fair value shown for natural gas contracts is comprised of derivative gross volumes totaling 626 billion cubic feet (Bcf) or a net 72 Bcf long position.  Of the net long position, basis swaps constitute 63 Bcf and volumes associated with price stabilization activities of the Natural Gas Distribution business segment comprise 26 Bcf.

(3) The net of total non-trading derivative assets and liabilities is a $15 million liability as shown on CenterPoint Energy’s Condensed Consolidated Balance Sheets, and is comprised of the natural gas contracts derivative assets and liabilities separately shown above offset by collateral netting of $84 million.

(1) Natural gas contracts are subject to master netting arrangements and are presented on a net basis in the Condensed Consolidated Balance Sheets. This netting causes derivative assets (liabilities) to be ultimately presented net in a liability (asset) account within the Condensed Consolidated Balance Sheets.

(2) The fair value shown for natural gas contracts is comprised of derivative gross volumes totaling 624 Bcf or a net 139 Bcf long position.  Of the net long position, basis swaps constitute 79 Bcf and volumes associated with price stabilization activities of the Natural Gas Distribution business segment comprise 17 Bcf.

(3) The net of total non-trading derivative assets and liabilities is a $4 million liability as shown on CenterPoint Energy’s Condensed Consolidated Balance Sheets, and is comprised of the natural gas contracts derivative assets and liabilities separately shown above offset by collateral netting of $55 million.

For CenterPoint Energy’s price stabilization activities of the Natural Gas Distribution business segment, the settled costs of derivatives are ultimately recovered through purchased gas adjustments. Accordingly, the net unrealized gains and losses associated with these contracts are recorded as net regulatory assets. Realized and

12

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

Income Statement Impact of Derivative Activity

(1) The Gains (Losses) in Expense: Natural Gas includes $(25) million and $(45) million of costs in 2010 and 2011, respectively, associated with price stabilization activities of the Natural Gas Distribution business segment that will be ultimately recovered through purchased gas adjustments.

(c) Credit Risk Contingent Features

CenterPoint Energy enters into financial derivative contracts containing material adverse change provisions.  These provisions could require CenterPoint Energy to post additional collateral if the Standard & Poor’s Ratings Services or Moody’s Investors Service, Inc. credit ratings of CenterPoint Energy, Inc. or its subsidiaries are downgraded.  The total fair value of the derivative instruments that contain credit risk contingent features that are in a net liability position at December 31, 2010 and March 31, 2011 was $107 million and $68 million, respectively.  The aggregate fair value of assets that are already posted as collateral was $31 million and $19 million, respectively, at December 31, 2010 and March 31, 2011.  If all derivative contracts (in a net liability position) containing credit risk contingent features were triggered at December 31, 2010 and March 31, 2011, $76 million and $48 million, respectively, of additional assets would be required to be posted as collateral.

(6)       Fair Value Measurements

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

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

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

Level 3: Inputs are unobservable for the asset or liability, and include situations where there is little, if any, market activity for the asset or liability. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, the level in the fair value hierarchy within which the fair value measurement in its entirety falls has been determined based on the lowest level input that is significant to the fair value measurement in its entirety. 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.

13

CenterPoint Energy determines the appropriate level for each financial asset and liability on a quarterly basis and recognizes any transfers at the end of the reporting period.  For the quarter ended March 31, 2011, there were no significant transfers between levels.

The following tables present information about CenterPoint Energy’s assets and liabilities (including derivatives that are presented net) measured at fair value on a recurring basis as of December 31, 2010 and March 31, 2011, and indicate the fair value hierarchy of the valuation techniques utilized by CenterPoint Energy to determine such fair value.

CenterPoint Energy has 1,020,000,000 authorized shares of capital stock, comprised of 1,000,000,000 shares of $0.01 par value common stock and 20,000,000 shares of $0.01 par value preferred stock. At December 31, 2010, 424,746,343 shares of CenterPoint Energy common stock were issued and 424,746,177 shares were outstanding. At March 31, 2011, 425,377,423 shares of CenterPoint Energy common stock were issued and 425,377,257 shares were outstanding. Outstanding common shares exclude 166 treasury shares at both December 31, 2010 and March 31, 2011.

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

(a) Short-term Borrowings

Receivables Facility. On September 15, 2010, CERC amended its receivables facility to extend the termination date to September 14, 2011. Availability under CERC’s receivables facility ranges from $160 million to $375 million, reflecting seasonal changes in receivables balances.  As of December 31, 2010 and March 31, 2011, the facility size was $160 million and $375 million, respectively. As of both December 31, 2010 and March 31, 2011, there were no advances under the receivables facility.

Inventory Financing. In October 2009, Gas Operations entered into asset management agreements associated with its utility distribution service in Arkansas, north Louisiana and Oklahoma that extend through March 31, 2012. Pursuant to the provisions of the agreements, Gas Operations sells natural gas and agrees to repurchase an equivalent amount of natural gas during the winter heating seasons at the same cost, plus a financing charge. These transactions are accounted for as a financing and they had an associated principal obligation of $53 million and $-0- as of December 31, 2010 and March 31, 2011, respectively.

(b) Long-term Debt

CERC Corp. Senior Notes.  In January 2011, CERC Corp. issued $250 million aggregate principal amount of senior notes due 2021 with an interest rate of 4.50% and $300 million aggregate principal amount of senior notes due 2041 with an interest rate of 5.85%.  The proceeds from the issuance of the notes were used for the repayment of $550 million of CERC Corp.’s 7.75% senior notes at their maturity in February 2011. Accordingly, the $550 million senior notes due in February 2011 are reflected as long-term debt as of December 31, 2010.

16

CERC Corp. Exchange Offer. Also in January 2011, CERC Corp. issued an additional $343 million aggregate principal amount of 4.50% senior notes due 2021 and provided cash consideration of $114 million in exchange for $397 million aggregate principal amount of its 7.875% senior notes due 2013.  The premium of $58 million paid on exchanged notes has been deferred and will be amortized to interest expense over the life of the 4.50% senior notes due 2021.

Revolving Credit Facilities. As of both December 31, 2010 and March 31, 2011, there were no outstanding borrowings under CenterPoint Energy’s, CenterPoint Houston’s or CERC Corp.’s long-term revolving credit facilities.

As of December 31, 2010 and March 31, 2011, CenterPoint Energy had approximately $20 million and $17 million, respectively, of outstanding letters of credit under its $1.2 billion credit facility. As of both December 31, 2010 and March 31, 2011, CenterPoint Houston had approximately $4 million of outstanding letters of credit under its $289 million credit facility. There was no commercial paper outstanding that would have been backstopped by CenterPoint Energy’s $1.2 billion credit facility as of December 31, 2010 or March 31, 2011.  As of December 31, 2010 and March 31, 2011, CERC Corp. had commercial paper outstanding of $183 million and $178 million, respectively, which was backstopped by its credit facility. CenterPoint Energy, CenterPoint Houston and CERC Corp. were in compliance with all debt covenants as of March 31, 2011.

CenterPoint Energy’s $1.2 billion credit facility has a first drawn cost of the London Interbank Offered Rate (LIBOR) plus 55 basis points based on CenterPoint Energy’s current credit ratings. The facility contains a debt (excluding transition and system restoration bonds) to earnings before interest, taxes, depreciation and amortization (EBITDA) covenant (as those terms are defined in the facility).  In February 2010, CenterPoint Energy amended its credit facility to modify the covenant to allow for a temporary increase of the permitted ratio from 5 times to 5.5 times if CenterPoint Houston experiences damage from a natural disaster in its service territory and CenterPoint Energy certifies to the administrative agent that CenterPoint Houston has incurred system restoration costs reasonably likely to exceed $100 million in a calendar year, all or part of which CenterPoint Houston intends to seek to recover through securitization financing. Such temporary increase in the financial ratio covenant would be in effect from the date CenterPoint Energy delivers its certification until the earliest to occur of (i) the completion of the securitization financing, (ii) the first anniversary of CenterPoint Energy’s certification or (iii) the revocation of such certification.

CenterPoint Houston’s $289 million credit facility contains a debt (excluding transition and system restoration bonds) to total capitalization covenant, limiting debt to 65% of its total capitalization. The facility’s first drawn cost is LIBOR plus 45 basis points based on CenterPoint Houston’s current credit ratings.

CERC Corp.’s $915 million credit facility’s first drawn cost is LIBOR plus 45 basis points based on CERC Corp.’s current credit ratings. The facility contains a debt to total capitalization covenant, limiting debt to 65% of its total capitalization.

Under CenterPoint Energy’s $1.2 billion credit facility, CenterPoint Houston’s $289 million credit facility and CERC Corp.’s $915 million credit facility, an additional utilization fee of 5 basis points applies to borrowings any time more than 50% of the facility is utilized. The spread to LIBOR and the utilization fee fluctuate based on the borrower’s credit rating.

(11)           Income Taxes

During the three months ended March 31, 2010 and 2011, the effective tax rate was 47% and 37%, respectively. The most significant item affecting the comparability of the effective tax rate is a non-cash, $21 million increase in the 2010 income tax expense as a result of a change in tax law upon the enactment in March 2010 of the Patient Protection and Affordable Care Act and the related Health Care and Education Reconciliation Act of 2010.

The change in tax law, which becomes effective for tax years beginning after December 31, 2012, eliminates the tax deductibility of the portion of retiree health care costs that are reimbursed by Medicare Part D subsidies. Based upon the actuarially determined net present value of lost future retiree health care deductions related to the subsidies, CenterPoint Energy reduced its deferred tax asset by approximately $32 million as of March 31, 2010.  The portion of the reduction that CenterPoint Energy believed would be recovered through the regulatory process, or

17

approximately $11 million, was recorded as an adjustment to regulatory assets.  The remaining $21 million of the reduction in CenterPoint Energy’s deferred tax asset was reflected as a charge to income tax expense.

On March 29, 2011, the IRS issued Revenue Procedure 2011-26 which provides guidance with respect to bonus depreciation as amended by the Tax Relief, Unemployment Insurance Reauthorization, and Job Creation Act of 2010 and the Small Business Jobs Act of 2010 (collectively, the “Acts”).  CenterPoint Energy has not finalized its evaluation of the revenue procedure or the associated tax implications.  However, CenterPoint Energy has incorporated in its quarterly results a reasonable estimate of the additional depreciation deductions it believes are supported by the IRS’s guidance.  Additionally, CenterPoint Energy believes the guidance will support additional depreciation deductions that can be claimed in its 2010 income tax returns.  As a result of the enactment of the Acts and the IRS’s guidance, CenterPoint Energy estimates it will have a tax net operating loss in each of 2010 and 2011.

The following table summarizes CenterPoint Energy’s unrecognized tax benefits at December 31, 2010 and March 31, 2011:

	December 31, 2010		March 31, 2011
	(in millions)
Unrecognized tax benefits	$	252	$	295
Portion of unrecognized tax benefits that, if recognized, would reduce the effective income tax rate		17		18
Interest accrued on unrecognized tax benefits		12		14

It is reasonably possible that the total amount of unrecognized tax benefits could decrease by as much as $266 million or increase by as much as $16 million over the next 12 months primarily as a result of the tax normalization issue described in Note 4(a) and the anticipated resolution of CenterPoint Energy’s administrative appeal relating to the IRS’s disallowance of CenterPoint Energy’s casualty loss deduction associated with the damage caused by Hurricane Ike.  Additionally, the tax normalization issue and the casualty loss deduction are temporary differences and, therefore, any increase or decrease in the balance of unrecognized tax benefits related thereto would not affect the effective tax rate.

In January 2011, the IRS commenced its examination of CenterPoint Energy’s 2008 and 2009 consolidated federal income tax returns.

(12)           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 Competitive Natural Gas Sales and 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 December 31, 2010 and March 31, 2011 as these contracts meet the exception to be classified as “normal purchases contracts” or do not meet the definition of a derivative. Natural gas supply commitments also include natural gas transportation contracts that do not meet the definition of a derivative. As of March 31, 2011, minimum payment obligations for natural gas supply commitments are approximately $250 million for the remaining nine months in 2011, $444 million in 2012, $442 million in 2013, $318 million in 2014, $200 million in 2015 and $413 million after 2015.

(b) Capital Commitments

Long-Term Gas Gathering and Treating Agreements

Magnolia Gathering System.  In September 2009, CenterPoint Energy Field Services, LLC (CEFS) entered into long-term agreements with an indirect wholly-owned subsidiary of Encana Corporation (Encana) and an indirect wholly-owned subsidiary of Royal Dutch Shell plc (Shell) to provide gathering and treating services for their natural gas production from certain Haynesville Shale and Bossier Shale formations in Louisiana.  Pursuant to these agreements, CEFS acquired jointly-owned gathering facilities (the Magnolia Gathering System) from Encana and

18

Shell in northwest Louisiana.  Each of the agreements includes acreage dedication and volume commitments for which CEFS has exclusive rights to gather Shell’s and Encana’s natural gas production.

During the fourth quarter of 2010, CEFS substantially completed the construction and initial expansion of the Magnolia Gathering System in order to permit the system to gather and treat up to 700 million cubic feet (MMcf) per day of natural gas, with only well connects remaining.  As of March 31, 2011, CEFS had spent approximately $320 million on the original project scope, including the purchase of the original facilities and is in the second year of the 10-year, 700 MMcf per day volume commitment made by Shell and Encana which commenced in September 2009.

Pursuant to an expansion election made by Encana and Shell in March 2010, CEFS expanded the Magnolia Gathering System to increase its gathering and treating capacity by an additional 200 MMcf per day, increasing the aggregate capacity of the system to 900 MMcf per day. The expansion was completed and placed into service in February 2011 at a total cost of approximately $52 million. The 200 MMcf per day incremental volume commitment made by Shell and Encana began contemporaneously with the completion of the expansion.

Under the long-term agreements, Encana or Shell may elect to require CEFS to expand the capacity of the Magnolia Gathering System by up to an additional 800 MMcf per day, bringing the total system capacity to 1.7 Bcf per day.  CEFS estimates that the cost to expand the capacity of the Magnolia Gathering System by an additional 800 MMcf per day would be as much as $240 million.  Encana and Shell would provide incremental volume commitments in connection with an election to expand the system’s capacity.

Olympia Gathering System.  In April 2010, CEFS entered into additional long-term agreements with Encana and Shell to provide gathering and treating services for their natural gas production from certain Haynesville Shale and Bossier Shale formations in Texas and Louisiana. Pursuant to these agreements, CEFS acquired jointly-owned gathering facilities (the Olympia Gathering System) from Encana and Shell in northwest Louisiana.

Under the terms of the agreements, CEFS is expanding the Olympia Gathering System in order to permit the system to gather and treat up to 600 MMcf per day of natural gas. As of March 31, 2011, CEFS had spent approximately $360 million on the 600 MMcf per day project, including the purchase of the original facilities, and expects to incur up to an additional $65 million to complete the remaining contractual milestones and well connects for this expansion.  CEFS is in the second year of the 10-year, 600 MMcf per day volume commitment made by Shell and Encana which commenced in April 2010.

Under the long-term agreements, Encana and Shell may elect to require CEFS to expand the capacity of the Olympia Gathering System by up to an additional 520 MMcf per day, bringing the total system capacity to 1.1 Bcf per day.  CEFS estimates that the cost to expand the capacity of the Olympia Gathering System by an additional 520 MMcf per day would be as much as $200 million. Encana and Shell would provide incremental volume commitments in connection with an election to expand the system’s capacity.

(c) Legal, Environmental and Other Regulatory Matters

Legal Matters

Gas Market Manipulation Cases.  CenterPoint Energy, CenterPoint Houston or their predecessor, Reliant Energy, Incorporated (Reliant Energy), and certain of their former subsidiaries are named as defendants in certain lawsuits described below. Under a master separation agreement between CenterPoint Energy and a former subsidiary, RRI Energy, Inc. (RRI), CenterPoint Energy and its subsidiaries are entitled to be indemnified by RRI and its successors for any losses, including attorneys’ fees and other costs, arising out of these lawsuits.  In May 2009, RRI sold its Texas retail business to NRG Retail LLC, a subsidiary of NRG Energy, Inc. and changed its name to RRI Energy, Inc. In December 2010, Mirant Corporation merged with and became a wholly owned subsidiary of RRI Energy, Inc., and RRI Energy, Inc. changed its name to GenOn Energy, Inc. (GenOn). Neither the sale of the retail business nor the merger with Mirant Corporation alters RRI’s (now GenOn’s) contractual obligations to indemnify CenterPoint Energy and its subsidiaries, including CenterPoint Houston, for certain liabilities, including their indemnification obligations regarding the gas market manipulation litigation, nor does it affect the terms of existing guaranty arrangements for certain GenOn gas transportation contracts discussed below.

19

A large number of lawsuits were filed against numerous gas market participants in a number of federal and western state courts in connection with the operation of the natural gas markets in 2000-2002. CenterPoint Energy’s former affiliate, RRI, was a participant in gas trading in the California and Western markets. These lawsuits, many of which have been filed as class actions, allege violations of state and federal antitrust laws. Plaintiffs in these lawsuits are seeking a variety of forms of relief, including, among others, recovery of compensatory damages (in some cases in excess of $1 billion), a trebling of compensatory damages, full consideration damages and attorneys’ fees. CenterPoint Energy and/or Reliant Energy were named in approximately 30 of these lawsuits, which were instituted between 2003 and 2009. CenterPoint Energy and its affiliates have been released or dismissed from all but two of such cases. CenterPoint Energy Services, Inc. (CES), a subsidiary of CERC Corp., is a defendant in a case now pending in federal court in Nevada alleging a conspiracy to inflate Wisconsin natural gas prices in 2000-2002.  Additionally, CenterPoint Energy was a defendant in a lawsuit filed in state court in Nevada that was dismissed in 2007, but in March 2010 the plaintiffs appealed the dismissal to the Nevada Supreme Court. CenterPoint Energy believes that neither it nor CES is a proper defendant in these remaining cases and will continue to pursue dismissal from those cases.  CenterPoint Energy does not expect the ultimate outcome of these remaining matters to have a material impact on its financial condition, results of operations or cash flows.

Natural Gas Measurement Lawsuits. CERC Corp. and certain of its subsidiaries are defendants in two mismeasurement lawsuits brought against approximately 245 pipeline companies and their affiliates pending in state court in Stevens County, Kansas.  In one case (originally filed in May 1999 and amended four times), the plaintiffs purport to represent a class of royalty owners who allege that the defendants have engaged in systematic mismeasurement of the volume of natural gas for more than 25 years. The plaintiffs amended their petition in this suit in July 2003 in response to an order from the judge denying certification of the plaintiffs’ alleged class. In the amendment, the plaintiffs dismissed their claims against certain defendants (including two CERC Corp. subsidiaries), limited the scope of the class of plaintiffs they purport to represent and eliminated previously asserted claims based on mismeasurement of the British thermal unit (Btu) content of the gas. The same plaintiffs then filed a second lawsuit, again as representatives of a putative class of royalty owners in which they assert their claims that the defendants have engaged in systematic mismeasurement of the Btu content of natural gas for more than 25 years. In both lawsuits, the plaintiffs seek compensatory damages, along with statutory penalties, treble damages, interest, costs and fees.  In September 2009, the district court in Stevens County, Kansas, denied plaintiffs’ request for class certification of their case and, in March 2010, denied the plaintiffs’ request for reconsideration of that order. The time for seeking further review of the district court’s decision has now passed.

CERC believes that there has been no systematic mismeasurement of gas and that these lawsuits are without merit. CERC and CenterPoint Energy do not expect the ultimate outcome of the lawsuits to have a material impact on the financial condition, results of operations or cash flows of either CenterPoint Energy or CERC.

Environmental Matters

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

At March 31, 2011, CERC had accrued $14 million for remediation of these Minnesota sites and the estimated range of possible remediation costs for these sites was $4 million to $35 million based on remediation continuing for 30 to 50 years. The cost estimates are based on studies of a site or industry average costs for remediation of sites of similar size. The actual remediation costs will be dependent upon the number of sites to be remediated, the participation of other potentially responsible parties (PRPs), if any, and the remediation methods used. The MPUC has provided for the inclusion in rates of approximately $285,000 annually to fund normal on-going remediation costs.  As of March 31, 2011, CERC had collected $5.2 million from insurance companies to be used for future environmental remediation.

In addition to the Minnesota sites, the United States Environmental Protection Agency and other regulators have investigated MGP sites that were owned or operated by CERC or may have been owned by one of its former affiliates. CERC has been named as a defendant in a lawsuit filed in the United States District Court, District of Maine, under which contribution is sought by private parties for the cost to remediate former MGP sites based on the previous ownership of such sites by former affiliates of CERC or its divisions. CERC has also been identified as a PRP by the State of Maine for a site that is a subject of the lawsuit. In June 2006, the federal district court in Maine

20

ruled that the current owner of the site is responsible for site remediation but that an additional evidentiary hearing would be required to determine if other potentially responsible parties, including CERC, would have to contribute to that remediation. In September 2009, the federal district court granted CERC’s motion for summary judgment in the proceeding.  Although it is likely that the plaintiff will pursue an appeal from that dismissal, further action will not be taken until the district court disposes of claims against other defendants in the case. CERC believes it is not liable as a former owner or operator of the site under the Comprehensive Environmental, Response, Compensation and Liability Act of 1980, as amended, and applicable state statutes, and is vigorously contesting the suit and its designation as a PRP. CERC and CenterPoint Energy do not expect the ultimate outcome to have a material adverse impact on the financial condition, results of operations or cash flows of either CenterPoint Energy or CERC.

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

Other Environmental. From time to time CenterPoint Energy has received notices from regulatory authorities or others regarding its status as a PRP in connection with sites found to require remediation due to the presence of environmental contaminants. In addition, CenterPoint Energy has been named from time to time as a defendant in litigation related to such sites. Although the ultimate outcome of such matters cannot be predicted at this time, CenterPoint Energy does not expect, based on its experience to date, these matters, either individually or in the aggregate, to have a material adverse effect on CenterPoint Energy’s financial condition, results of operations or cash flows.

Other Proceedings

CenterPoint Energy is involved in other legal, environmental, tax and regulatory proceedings before various courts, regulatory commissions and governmental agencies regarding matters arising in the ordinary course of business. Some of these proceedings involve substantial amounts. CenterPoint Energy regularly analyzes current information and, as necessary, provides accruals for probable liabilities on the eventual disposition of these matters. CenterPoint Energy does not expect the disposition of these matters to have a material adverse effect on CenterPoint Energy’s financial condition, results of operations or cash flows.

(d) Guaranties

Prior to the distribution of CenterPoint Energy’s ownership in RRI to its shareholders, CERC had guaranteed certain contractual obligations of what became RRI’s trading subsidiary.  When the companies separated, RRI agreed to secure CERC against obligations under the guaranties RRI had been unable to extinguish by the time of separation.  Pursuant to such agreement, as amended in December 2007, RRI (now GenOn) agreed to provide to CERC cash or letters of credit as security against CERC’s obligations under its remaining guaranties for demand charges under certain gas transportation agreements if and to the extent changes in market conditions expose CERC to a risk of loss on those guaranties based on an annual calculation, with any required collateral to be posted each December.  The undiscounted maximum potential payout of the demand charges under these transportation contracts, which will be in effect until 2018, was approximately $109 million as of March 31, 2011. Market conditions in the fourth quarter of 2010 required posting of security under the agreement, and GenOn posted approximately $7 million in collateral in December 2010.  If GenOn should fail to perform the contractual obligations, CERC could have to honor its guarantee and, in such event, collateral provided as security may be insufficient to satisfy CERC’s obligations.

(14)           Reportable Business Segments

CenterPoint Energy’s determination of reportable business segments considers the strategic operating units under which CenterPoint Energy manages sales, allocates resources and assesses performance of various products and services to wholesale or retail customers in differing regulatory environments. CenterPoint Energy uses operating income as the measure of profit or loss for its business segments.

CenterPoint Energy’s reportable business segments include the following: Electric Transmission & Distribution, Natural Gas Distribution, Competitive Natural Gas Sales and Services, Interstate Pipelines, Field Services and Other Operations. The electric transmission and distribution function (CenterPoint Houston) is reported in the Electric Transmission & Distribution business segment. Natural Gas Distribution consists of intrastate natural gas sales to, and natural gas transportation and distribution for, residential, commercial, industrial and institutional customers. Competitive Natural Gas Sales and Services represents CenterPoint Energy’s non-rate regulated gas sales and services operations, which consist of the following operational functions: wholesale, retail and intrastate pipelines. The Interstate Pipelines business segment includes the interstate natural gas pipeline operations. The Field Services business segment includes the non-rate regulated natural gas gathering, processing and treating operations. Other Operations consists primarily of other corporate operations which support all of CenterPoint Energy’s business operations.

Item 2.          MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS OF CENTERPOINT ENERGY, INC. AND SUBSIDIARIES

The following discussion and analysis should be read in combination with our Interim Condensed Financial Statements contained in this Form 10-Q and our Annual Report on Form 10-K for the year ended December 31, 2010 (2010 Form 10-K).

EXECUTIVE SUMMARY

Recent Events

Texas Supreme Court Ruling on True-Up Appeal

On March 18, 2011, the Texas Supreme Court issued a unanimous ruling on the appeals of the final order (True-Up Order) issued in 2004 by the Public Utility Commission of Texas (Texas Utility Commission) in connection with CenterPoint Energy Houston Electric, LLC’s (CenterPoint Houston) stranded cost and true-up application. The Texas Supreme Court affirmed in part and reversed in part the decision of the Texas Utility Commission and remanded the matter to the Texas Utility Commission for further proceedings.

CenterPoint Houston originally filed its True-Up Application with the Texas Utility Commission requesting recovery of $3.7 billion, excluding interest, as allowed under the Texas Electric Choice Plan (Texas electric restructuring law). In December 2004, the Texas Utility Commission issued its True-Up Order allowing us to recover a true-up balance of approximately $2.3 billion, which included interest through August 31, 2004, and provided for certain other adjustments. To reflect the impact of the True-Up Order, in 2004 and 2005, we recorded a net after-tax extraordinary loss of $947 million.  CenterPoint Houston and a number of other parties appealed the Texas Utility Commission’s decision to a district court in Travis County, Texas, the Texas Third Court of Appeals (court of appeals) and, ultimately, to the Texas Supreme Court.

The impact of the Texas Supreme Court’s decision regarding the matters on appeal with respect to the True-Up Order is summarized as follows:

• The method used by the Texas Utility Commission to calculate the market value of our former generating assets was overturned. In its decision, the Texas Utility Commission had rejected the partial stock valuation method CenterPoint Houston utilized to establish the market value of the generating assets, and the Texas Utility Commission had fashioned its own valuation. The Texas Supreme Court ruled that the Texas Utility Commission had no authority to craft an alternative valuation methodology but instead should have valued the generating assets at the value established when we later sold our Texas Genco subsidiary. This portion of the decision requires that the valuation question be remanded to the Texas Utility Commission for a determination. We currently estimate that application of the sale of assets methodology would reduce stranded costs by approximately $252 million, less selling costs, with the amount ultimately determined (plus interest) subtracted from the amounts eligible for recovery in the remand proceeding.  This portion of the decision is unfavorable to us.

• The Texas Utility Commission’s order denying recovery of approximately $440 million in capacity auction true-up amounts was reversed. This portion of the decision is favorable to us. These sums plus interest are eligible for recovery in the remand proceeding.

• The Texas Utility Commission’s refusal to include approximately $378 million related to depreciation in the calculation of stranded costs was reversed. This portion of the decision is favorable to us. These sums plus interest are eligible for recovery in the remand proceeding.

• The Texas Utility Commission’s order allowing recovery of excess mitigation credits (EMCs) that we had been ordered to pay our former affiliate was upheld. This portion of the decision is favorable to us. These sums have already been recovered and will not be addressed in the remand proceeding.

• The Texas Utility Commission decisions allowing recovery of construction work in progress balances and interest on the capacity auction true-up amounts were upheld. These decisions are favorable to us. These sums have already been recovered and will not be addressed in the remand proceeding.

24

The Texas Supreme Court did not address the court of appeals’ decision allowing CenterPoint Houston to recover approximately $210 million representing the interest component of the EMCs. This decision, which was favorable to us, was not appealed to the Texas Supreme Court. These sums plus interest are eligible for recovery in the remand proceeding.

Among the issues to be taken up by the Texas Utility Commission on the remand from the Texas Supreme Court is the proper regulatory treatment of certain deferred tax benefits.  In the True-Up Order, the Texas Utility Commission reduced CenterPoint Houston’s true-up balance by approximately $146 million, which was included in the extraordinary loss discussed above, to reflect the present value of certain deferred tax benefits associated with our former electric generation assets. We believe that the Texas Utility Commission based its order on proposed regulations issued by the Internal Revenue Service (IRS) in March 2003 that would have allowed utilities owning assets that were deregulated before March 4, 2003 to make a retroactive election to pass the benefits of Accumulated Deferred Investment Tax Credits (ADITC) and Excess Deferred Federal Income Taxes (EDFIT) back to customers. However, the IRS subsequently withdrew those proposed normalization regulations and, in March 2008, adopted final regulations that would not permit utilities like CenterPoint Houston to pass the tax benefits back to customers without creating normalization violations. In addition, we received a Private Letter Ruling (PLR) from the IRS in August 2007, prior to adoption of the final regulations, that confirmed that the Texas Utility Commission’s order reducing CenterPoint Houston’s stranded cost recovery by $146 million for ADITC and EDFIT would cause normalization violations with respect to the ADITC and EDFIT. The Texas Utility Commission thereafter requested that this issue be remanded to that commission for further consideration, and that request was granted by the court of appeals.  CenterPoint Houston plans to seek to recover $146 million plus interest related to this issue in the remand proceedings.

If the Texas Utility Commission’s order relating to the ADITC reduction is not reversed or otherwise modified on remand so as to eliminate the normalization violation, the IRS could require us to pay an amount equal to CenterPoint Houston’s unamortized ADITC balance as of the date that the normalization violation is deemed to have occurred. In addition, the IRS could deny CenterPoint Houston the ability to elect accelerated tax depreciation benefits beginning in the taxable year that the normalization violation is deemed to have occurred. Such treatment, if required by the IRS, could have a material adverse impact on our results of operations, financial condition and cash flows.

A number of parties have asked the Texas Supreme Court to reconsider its decision.  The court has 180 days from the filing of a motion for rehearing to rule on that request.  The remand to the Texas Utility Commission for further proceedings will not occur until after the court has acted on the motions for rehearing.  There is no statutory deadline by which the Texas Utility Commission must act once the case has been remanded to it; but, in accordance with the rules of the Texas Utility Commission, interest on the unsecuritized true-up balance will continue to accrue until such time as the unrecovered true-up balance is securitized or is otherwise reflected in rates.

If the Texas Supreme Court’s decision is not modified as a result of the motions for rehearing and becomes final, CenterPoint Houston expects to seek recovery of approximately $1.85 billion, which includes interest through September 30, 2011. Interest on the true up balance would continue to accrue at approximately 8% if securitization bonds are not issued on or before September 30, 2011.  We expect to record the effects of the Texas Supreme Court’s decision once a final resolution of these matters is reached.

The final resolution of the true-up proceedings and the ultimate amount and timing of recovery of the additional amount authorized will depend upon the outcome of requests to the Texas Supreme Court for rehearing, future actions by the Texas Utility Commission in response to rulings by the Texas Supreme Court and the court of appeals, and any future appeals thereof.  CenterPoint Houston intends to file an application with the Texas Utility Commission for approval of a financing order authorizing the issuance of transition bonds by one or more new special purpose subsidiaries of CenterPoint Houston to securitize the recoverable amounts and certain qualified costs.

Long-Term Gas Gathering and Treating Agreements

Magnolia Gathering System.  In September 2009, CenterPoint Energy Field Services, LLC (CEFS) entered into long-term agreements with an indirect wholly-owned subsidiary of Encana Corporation (Encana) and an indirect wholly-owned subsidiary of Royal Dutch Shell plc (Shell) to provide gathering and treating services for their natural gas production from certain Haynesville Shale and Bossier Shale formations in Louisiana.  Pursuant to these agreements, CEFS acquired jointly-owned gathering facilities (the Magnolia Gathering System) from Encana and Shell in northwest Louisiana.  Each of the agreements includes acreage dedication and volume commitments for which CEFS has exclusive rights to gather Shell’s and Encana’s natural gas production.

During the fourth quarter of 2010, CEFS substantially completed the construction and initial expansion of the Magnolia Gathering System in order to permit the system to gather and treat up to 700 million cubic feet (MMcf) per day of natural gas, with only well connects remaining.  As of March 31, 2011, CEFS had spent approximately $320 million on the original project scope, including the purchase of the original facilities and is in the second year of the 10-year, 700 MMcf per day volume commitment made by Shell and Encana which commenced in September 2009.

Pursuant to an expansion election made by Encana and Shell in March 2010, CEFS expanded the Magnolia Gathering System to increase its gathering and treating capacity by an additional 200 MMcf per day, increasing the aggregate capacity of the system to 900 MMcf per day. The expansion was completed and placed into service in February 2011 at a total cost of approximately $52 million. The 200 MMcf per day incremental volume commitment made by Shell and Encana began contemporaneously with the completion of the expansion.

Under the long-term agreements, Encana or Shell may elect to require CEFS to expand the capacity of the Magnolia Gathering System by up to an additional 800 MMcf per day, bringing the total system capacity to 1.7 billion cubic feet (Bcf) per day.  CEFS estimates that the cost to expand the capacity of the Magnolia Gathering System by an additional 800 MMcf per day would be as much as $240 million.  Encana and Shell would provide incremental volume commitments in connection with an election to expand the system’s capacity.

Olympia Gathering System.  In April 2010, CEFS entered into additional long-term agreements with Encana and Shell to provide gathering and treating services for their natural gas production from certain Haynesville Shale and Bossier Shale formations in Texas and Louisiana. Pursuant to these agreements, CEFS acquired jointly-owned gathering facilities (the Olympia Gathering System) from Encana and Shell in northwest Louisiana.

Under the terms of the agreements, CEFS is expanding the Olympia Gathering System in order to permit the system to gather and treat up to 600 MMcf per day of natural gas. As of March 31, 2011, CEFS had spent approximately $360 million on the 600 MMcf per day project, including the purchase of the original facilities, and expects to incur up to an additional $65 million to complete the remaining contractual milestones and well connects for this expansion.  CEFS is in the second year of the 10-year, 600 MMcf per day volume commitment made by Shell and Encana which commenced in April 2010.

Under the long-term agreements, Encana and Shell may elect to require CEFS to expand the capacity of the Olympia Gathering System by up to an additional 520 MMcf per day, bringing the total system capacity to 1.1 Bcf per day.  CEFS estimates that the cost to expand the capacity of the Olympia Gathering System by an additional 520 MMcf per day would be as much as $200 million. Encana and Shell would provide incremental volume commitments in connection with an election to expand the system’s capacity.

Advanced Metering System and Distribution Grid Automation (Intelligent Grid)

In October 2009, the U.S. Department of Energy (DOE) notified CenterPoint Energy Houston that it had been selected for a $200 million grant for its advanced metering system (AMS) and intelligent grid (IG) projects.  In March 2010, CenterPoint Houston and the DOE completed negotiations and finalized the agreement. Under the terms of agreement, the DOE has agreed to reimburse CenterPoint Houston for 50% of its eligible costs until the total amount of the grant has been paid.  Through March 31, 2011, CenterPoint Houston has requested $135 million of grant funding from the DOE, of which $122 million had been received. CenterPoint Houston estimates that capital expenditures of approximately $645 million for the installation of the advanced meters and corresponding communication and data management systems will be incurred over the deployment period. CenterPoint Houston is using $150 million of the grant funding to accelerate completion of its current deployment of advanced meters to

26

2012, instead of 2014 as originally scheduled.  CenterPoint Houston will use the other $50 million from the grant for an initial deployment of an IG in a portion of its service territory to be completed in 2013.  It is expected that the portion of the IG project subject to funding by the DOE will cost approximately $115 million.  CenterPoint Houston believes the IG has the potential to provide an improvement in grid planning, operations, maintenance and customer service for its distribution system.

In March 2010, the Internal Revenue Service (IRS) announced through the issuance of Revenue Procedure 2010-20 that it was providing a safe harbor to corporations that receive a Smart Grid Investment Grant. The IRS stated that it would not challenge a corporation’s treatment of the grant as a non-taxable non-shareholder contribution to capital as long as the corporation properly reduced the tax basis of specified property acquired.

CenterPoint Houston 2010 Rate Case

As required under a final order in its 2006 rate proceeding, in June 2010 CenterPoint Houston filed an application to change rates with the Texas Utility Commission and the cities in its service area.  The filing included cost data and other information supporting an annual increase of $106 million for delivery charges to the retail electric providers (REPs) that sell electricity to end-use customers in CenterPoint Houston’s service territory partially offset by a reduction of other utility revenues, resulting in a $92 million requested annual revenue increase. The rate filing package also supported an annual increase of $18 million for wholesale transmission customers.

In the filing, CenterPoint Houston also requested reconciliation of its AMS costs incurred as of March 31, 2010, and revision of the estimated costs to complete the AMS project in order to reflect $150 million in funds from the $200 million DOE stimulus grant awarded to CenterPoint Houston and updated cost information. The reconciliation plan also requested that the duration of the residential AMS surcharge be shortened by six years from the original 12-year plan.

CenterPoint Houston’s filing sought a return on equity of 11.25% and proposed that rates be based on a capital structure of 50% equity and 50% long-term debt.

Hearings concerning the rate filing concluded in October 2010, and a Proposal for Decision was issued by the presiding Administrative Law Judges.  On February 3, 2011 the Texas Utility Commission voted on the various contested issues presented by the rate filing, and on April 29, 2011, the Texas Utility Commission voted to approve a draft final order conforming to its prior deliberations, subject to certain administrative revisions. CenterPoint Houston expects that order to be issued in the next several weeks but that revised rates based on that order would not be implemented before the third quarter.  The final order will be subject to revision based on motions for rehearing filed by the parties to the proceeding and could be appealed to the Texas courts.

The order of the Texas Utility Commission will provide for a base rate increase for CenterPoint Houston of approximately $14.7 million per year for delivery charges to the REPs and a decrease to charges to wholesale transmission customers of $12.3 million per year.  Further, the order will adopt a mechanism to track amounts for uncertain tax positions and provide for ultimate recovery of those costs.

The order will be based on an authorized return on equity for CenterPoint Houston of 10%, a cost of debt of ­6.74­%, a capital structure comprised of 55% debt and 45% common equity, and an overall rate of return of 8.21%.  The decision also will implement CenterPoint Houston’s request to reconcile costs incurred for the AMS project and to shorten the period for collecting the AMS surcharge from twelve to six years for residential customers in order to reflect the funds received from the DOE.

Based on CenterPoint Houston’s understanding of the Texas Utility Commission’s draft order, CenterPoint Houston anticipates that normalized annual operating income will be reduced by approximately $30 million from 2010 levels as a result of the Texas Utility Commission’s decision.

Debt Financing Transactions

In January 2011, CERC Corp. issued $250 million aggregate principal amount of senior notes due 2021 with an interest rate of 4.50% and $300 million aggregate principal amount of senior notes due 2041 with an interest rate of 5.85%.  The proceeds from the issuance of the notes were used for the repayment of $550 million of CERC Corp.’s 7.75% senior notes at their maturity in February 2011.

27

Also in January 2011, CERC Corp. issued an additional $343 million aggregate principal amount of 4.50% senior notes due 2021 and provided cash consideration of $114 million in exchange for $397 million aggregate principal amount of its 7.875% senior notes due 2013.  The premium of $58 million paid on exchanged notes has been deferred and will be amortized to interest expense over the life of the 4.50% senior notes due 2021.

Financial Reform Legislation

On July 21, 2010, the President signed into law the Dodd-Frank Wall Street Reform and Consumer Protection Act (Dodd-Frank), which makes substantial changes to regulatory oversight regarding banks and financial institutions.  Many provisions of Dodd-Frank will also affect non-financial businesses such as those conducted by us and our subsidiaries. It is not possible at this time to predict the ultimate impacts this legislation may have on us and our subsidiaries since most of the provisions in the law will require extensive rulemaking by various regulatory agencies and authorities, including, among others, the Securities and Exchange Commission (SEC), the Commodities Futures Trading Commission (CFTC) and the New York Stock Exchange (NYSE). Nevertheless, in a number of areas, the resulting rules are expected to have direct or indirect impacts on our businesses.

Dodd-Frank provisions will increase required disclosures regarding executive compensation, and rules adopted by the SEC in January 2011 required an advisory vote at our 2011 annual meeting by shareholders on executive compensation (“say-on-pay”) and required an advisory vote by shareholders on the frequency that such say-on-pay votes will be submitted in future years. New rules adopted by the SEC, which would not apply to us until 2012, are intended to provide shareholders with access to the director nomination process, but those rules have been stayed by the SEC in light of pending legal challenges.

Although Dodd-Frank includes significant new provisions regarding the regulation of derivatives, the impact of those requirements will not be known definitively until regulations have been adopted by the SEC and the CFTC. The SEC is charged with adopting new regulations regarding securitization transactions such as the asset-backed securitizations CenterPoint Houston has sponsored for recovery of transition and storm restoration costs.  Dodd-Frank also includes new whistleblower provisions.

Dodd-Frank also makes substantial changes to the regulatory oversight of the credit rating agencies that are typically engaged to rate our securities and those of our subsidiaries.  It is presently unknown what effect implementation of these new provisions ultimately will have on the activities or costs associated with the credit rating process.

Three months ended March 31, 2011 compared to three months ended March 31, 2010

We reported consolidated net income of $148 million ($0.35 per diluted share) for the three months ended March 31, 2011 compared to $114 million ($0.29 per diluted share) for the same period in 2010. The increase in net income of $34 million was primarily due to a $15 million decrease in income tax expense, a $7 million increase in operating income (discussed by segment below), a $6 million decrease in interest expense due to lower levels of debt, excluding transition and system restoration bond-related interest expense and a $4 million decrease in the loss on our indexed debt securities, which were partially offset by a $6 million decrease in the gain on our marketable securities.

Income Tax Expense

During the three months ended March 31, 2010 and 2011, our effective tax rate was 47% and 37%, respectively. The most significant item affecting the comparability of our effective tax rate is a non-cash, $21 million increase in the 2010 income tax expense as a result of a change in tax law upon the enactment in March 2010 of the Patient Protection and Affordable Care Act and the related Health Care and Education Reconciliation Act of 2010.

The change in tax law, which becomes effective for tax years beginning after December 31, 2012, eliminates the tax deductibility of the portion of retiree health care costs that are reimbursed by Medicare Part D subsidies. Based upon the actuarially determined net present value of lost future retiree health care deductions related to the subsidies, we reduced our deferred tax asset by approximately $32 million as of March 31, 2010.  The portion of the reduction that we believed would be recovered through the regulatory process, or approximately $11 million, was recorded as an adjustment to regulatory assets.  The remaining $21 million of the reduction in our deferred tax asset was reflected as a charge to income tax expense.

On March 29, 2011, the IRS issued Revenue Procedure 2011-26 which provides guidance with respect to bonus depreciation as amended by the Tax Relief, Unemployment Insurance Reauthorization, and Job Creation Act of 2010 and the Small Business Jobs Act of 2010 (collectively, the “Acts”).  We have not finalized our evaluation of the revenue procedure or the associated tax implications.  However, we have incorporated in our quarterly results a reasonable estimate of the additional depreciation deductions we believe are supported by the IRS’s guidance.  Additionally, we believe the guidance will support additional depreciation deductions that can be claimed in our 2010 income tax returns.  As a result of the enactment of the Acts and the IRS’s guidance, we estimate we will have a tax net operating loss in each of 2010 and 2011.

Three months ended March 31, 2011 compared to three months ended March 31, 2010

Our Electric Transmission & Distribution business segment reported operating income of $101 million for the three months ended March 31, 2011, consisting of $68 million from the regulated electric transmission and distribution utility (TDU) and $33 million related to transition and system restoration bond companies. For the three months ended March 31, 2010, operating income totaled $107 million, consisting of $71 million from the TDU and $36 million related to transition and system restoration bond companies. TDU revenues increased $14 million primarily due to higher transmission-related revenues ($12 million), revenues from implementation of the AMS ($6 million) and higher revenues due to customer growth ($3 million) from the addition of over 29,000 new customers, partially offset by the timing of energy efficiency spending ($4 million).  Operation and maintenance expenses increased due to higher transmission costs billed by transmission providers ($11 million), increased AMS project expenses ($3 million) and other operating expense increases ($4 million).

Three months ended March 31, 2011 compared to three months ended March 31, 2010

Our Natural Gas Distribution business segment reported operating income of $142 million for the three months ended March 31, 2011 compared to $139 million for the three months ended March 31, 2010.  Operating income increased $3 million primarily as a result of lower bad debt expense ($6 million) related to improved collection efforts, partially offset by increased other expenses ($2 million).  The revenue impacts of warmer weather were mitigated by weather hedges, weather normalization adjustments and increased throughput to large-volume customers.  Expenses related to both energy efficiency programs and gross receipts taxes are substantially offset by the related revenues.

Competitive Natural Gas Sales and Services

Three months ended March 31, 2011 compared to three months ended March 31, 2010

Our Competitive Natural Gas Sales and Services business segment reported operating income of $10 million for the three months ended March 31, 2011 compared to $15 million for the three months ended March 31, 2010.  The decrease in operating income of $5 million is primarily due to the unfavorable impact of the mark-to-market valuation for non-trading financial derivatives in 2011 of $2 million versus a favorable impact of $3 million for the same period in 2010. Reduced basis spreads on pipeline transport opportunities and decreased winter storage spreads continued to impact this segment in the first quarter of 2011 as they did in 2010. Throughput volumes and the number of customers increased in the first quarter of 2011 compared to the first quarter of 2010 as a result of growth in this segment’s retail business.

Three months ended March 31, 2011 compared to three months ended March 31, 2010

Our Interstate Pipeline business segment reported operating income of $76 million for the three months ended March 31, 2011 compared to $72 million for the three months ended March 31, 2010.  Margins (revenues less natural gas costs) increased $1 million primarily due to the Carthage to Perryville pipeline ($4 million) and new power plant transportation contracts ($2 million), partially offset by reduced other transportation margins and ancillary services ($5 million).  Operation and maintenance expenses were lower ($4 million) primarily due to an insurance settlement related to a damaged compressor station, which was partially offset by higher taxes other than income ($1 million).

Equity Earnings.  In addition, this business segment recorded equity income of $3 million and $4 million for the three months ended March 31, 2010 and 2011, respectively, from its 50% interest in the Southeast Supply Header, a jointly-owned pipeline.  These amounts are included in Equity in Earnings of Unconsolidated Affiliates under the Other Income (Expense) caption.

Our Field Services business segment reported operating income of $36 million for the three months ended March 31, 2011 compared to $23 million for the three months ended March 31, 2010.  Margins increased primarily from the Magnolia and Olympia Gathering Systems in the North Louisiana Haynesville Shale ($26 million), partially offset by the effects of lower natural gas prices for retained volumes on the system ($3 million). Increases in operating expenses ($8 million) and depreciation and amortization ($3 million) were primarily due to the projects in the Haynesville Shale.

Equity Earnings.  In addition, this business segment recorded equity income of $2 million in both the three months ended March 31, 2010 and 2011 from its 50% general partnership interest in Waskom Gas Processing Company.  These amounts are included in Equity in Earnings of Unconsolidated Affiliates under the Other Income (Expense) caption.

Net cash provided by operating activities in the first three months of 2011 increased $192 million compared to the same period in 2010 due to increased tax refunds ($152 million), decreased net margin deposits ($103 million) and increased net income ($34 million), which were partially offset by decreased cash provided by fuel cost recovery ($113 million).

Cash Used in Investing Activities

Net cash used in investing activities in the first three months of 2011 increased $5 million compared to the same period in 2010 due to increased capital expenditures ($75 million), primarily related to Field Services projects, which were partially offset by decreased investment in unconsolidated affiliates ($17 million) and cash received from the DOE grant ($32 million).

Cash Used in Financing Activities

Net cash used in financing activities in the first three months of 2011 decreased $120 million compared to the same period in 2010 due to increased proceeds from long-term debt ($550 million), which were partially offset by increased payments of long-term debt ($325 million), increased cash paid for debt exchange ($58 million), decreased proceeds from the issuance of common stock ($27 million), increased common stock dividend payments ($7 million) and increased debt issuance costs ($7 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, various regulatory actions and appeals relating to such regulatory actions. Our principal cash requirements for the remaining nine months of 2011 include the following:

• capital expenditures of approximately $1.1 billion;

• $143 million of scheduled principal payments on transition and system restoration bonds; and

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

We expect that proceeds from sales of commercial paper, borrowings under our credit facilities and anticipated cash flows from operations will be sufficient to meet our anticipated cash needs for the remaining nine months of 2011. Cash needs or 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 the guaranties described below and operating leases, we have no off-balance sheet arrangements.

Prior to the distribution of our ownership in RRI Energy, Inc. (RRI) to our shareholders, CERC had guaranteed certain contractual obligations of what became RRI’s trading subsidiary.  When the companies separated, RRI agreed to secure CERC against obligations under the guaranties RRI had been unable to extinguish by the time of separation.  Pursuant to such agreement, as amended in December 2007, RRI (now named GenOn Energy, Inc. (GenOn)) agreed to provide to CERC cash or letters of credit as security against CERC’s obligations under its remaining guaranties for demand charges under certain gas transportation agreements if and to the extent changes in market conditions expose CERC to a risk of loss on those guaranties based on an annual calculation, with any required collateral to be posted each December.  The undiscounted maximum potential payout of the demand charges under these transportation contracts, which will be in effect until 2018, was approximately $109 million as of March 31, 2011.  Market conditions in the fourth quarter of 2010 required posting of security under the agreement, and GenOn posted approximately $7 million in collateral in December 2010. If GenOn should fail to perform the contractual obligations, CERC could have to honor its guarantee and, in such event, collateral provided as security may be insufficient to satisfy CERC’s obligations.

In May 2009, RRI sold its Texas retail business to NRG Retail LLC, a subsidiary of NRG Energy, Inc. In December 2010, Mirant Corporation merged with and became a wholly owned subsidiary of RRI and RRI changed its name from RRI Energy, Inc. to GenOn Energy, Inc. Neither the sale of the retail business nor the merger with Mirant Corporation alters GenOn’s contractual obligations to indemnify us and our subsidiaries, including CenterPoint Houston, for certain liabilities, including their indemnification obligations regarding certain litigation, nor does it affect the terms of existing guaranty arrangements for certain GenOn gas transportation contracts.

Debt Financing Transactions.  In January 2011, CERC Corp. issued $250 million aggregate principal amount of senior notes due 2021 with an interest rate of 4.50% and $300 million aggregate principal amount of senior notes due 2041 with an interest rate of 5.85%.  The proceeds from the issuance of the notes were used for the repayment of $550 million of CERC Corp.’s 7.75% senior notes at their maturity in February 2011.

Also in January 2011, CERC Corp. issued an additional $343 million aggregate principal amount of 4.50% senior notes due 2021 and provided cash consideration of $114 million in exchange for $397 million aggregate principal amount of its 7.875% senior notes due 2013.  The premium of $58 million paid on exchanged notes has been deferred and will be amortized to interest expense over the life of the 4.50% senior notes due 2021.

Credit and Receivables Facilities. As of April 15, 2011, we had the following facilities (in millions):

Date Executed	Company	Type of Facility	Size of Facility		Amount Utilized at April 15, 2011 (1)			Termination Date
June 29, 2007	CenterPoint Energy	Revolver	$	1,156	$	17	(2)	June 29, 2012
June 29, 2007	CenterPoint Houston	Revolver		289		4	(2)	June 29, 2012
June 29, 2007	CERC Corp.	Revolver		915		52	(3)	June 29, 2012
September 15, 2010	CERC	Receivables		375		—		September 14, 2011

(1) Based on the debt (excluding transition and system restoration bonds) to earnings before interest, taxes, depreciation and amortization (EBITDA) covenant contained in our $1.2 billion credit facility, we would have been permitted to utilize the full capacity of our credit facilities of $2.4 billion at March 31, 2011. Amounts advanced under CERC’s receivables facility are not treated as outstanding indebtedness in the debt to EBITDA covenant calculation.

(2) Represents outstanding letters of credit.

(3) Represents commercial paper that is backstopped by CERC Corp.’s revolving credit facility.

Our $1.2 billion credit facility has a first drawn cost of London Interbank Offered Rate (LIBOR) plus 55 basis points based on our current credit ratings. The facility contains a debt (excluding transition and system restoration bonds) to EBITDA covenant (as those terms are defined in the facility).  In February 2010, we amended our credit facility to modify the covenant to allow for a temporary increase of the permitted ratio from 5 times to 5.5 times if

35

CenterPoint Houston experiences damage from a natural disaster in its service territory and we certify to the administrative agent that CenterPoint Houston has incurred system restoration costs reasonably likely to exceed $100 million in a calendar year, all or part of which CenterPoint Houston intends to seek to recover through securitization financing. Such temporary increase in the financial ratio covenant would be in effect from the date we deliver our certification until the earliest to occur of (i) the completion of the securitization financing, (ii) the first anniversary of our certification or (iii) the revocation of such certification.

CenterPoint Houston’s $289 million credit facility contains a debt (excluding transition and system restoration bonds) to total capitalization covenant, limiting debt to 65% of its total capitalization. The facility’s first drawn cost is LIBOR plus 45 basis points based on CenterPoint Houston’s current credit ratings.

CERC Corp.’s $915 million credit facility’s first drawn cost is LIBOR plus 45 basis points based on CERC Corp.’s current credit ratings. The facility contains a debt to total capitalization covenant, limiting debt to 65% of its total capitalization.

Under our $1.2 billion credit facility, CenterPoint Houston’s $289 million credit facility and CERC Corp’s $915 million credit facility, an additional utilization fee of 5 basis points applies to borrowings any time more than 50% of the facility is utilized. The spread to LIBOR and the utilization fee fluctuate based on the borrower’s credit rating.

Borrowings under each of the facilities are subject to customary terms and conditions. However, there is no requirement that we, CenterPoint Houston or CERC Corp. 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 credit facilities are subject to acceleration upon the occurrence of events of default that we, CenterPoint Houston or CERC Corp. consider customary.

We, CenterPoint Houston and CERC Corp. are currently in compliance with the various business and financial covenants contained in the respective credit facilities as disclosed above.

Our $1.2 billion credit facility backstops a $1.0 billion CenterPoint Energy commercial paper program under which we began issuing commercial paper in June 2005. The $915 million CERC Corp. credit facility backstops a $915 million commercial paper program under which CERC Corp. began issuing commercial paper in February 2008. As of March 31, 2011, CERC Corp. had $178 million of outstanding commercial paper. As a result of the credit ratings on the two commercial paper programs, we do not expect to be able to rely on the sale of commercial paper to fund all of our short-term borrowing requirements.

During the first quarter of 2011, CERC met a portion of its liquidity requirements with commercial paper proceeds.  We currently expect that CERC may be required to continue to access financing sources, in addition to money pool borrowings, in order to satisfy its liquidity requirements in 2011.  These sources could include commercial paper proceeds or borrowings under CERC Corp.’s revolving credit or receivables facilities.

Securities Registered with the SEC. CenterPoint Energy, CenterPoint Houston and CERC Corp. have filed a joint shelf registration statement with the SEC registering indeterminate principal amounts of CenterPoint Houston’s general mortgage bonds, CERC Corp.’s senior debt securities and CenterPoint Energy’s senior debt securities and junior subordinated debt securities and an indeterminate number of CenterPoint Energy’s shares of common stock, shares of preferred stock, as well as stock purchase contracts and equity units.

Temporary Investments. As of April 15, 2011, we had no external temporary investments.

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

36

Impact on Liquidity of a Downgrade in Credit Ratings. The interest on borrowings under our credit facilities is based on our credit rating. As of April 28, 2011, Moody’s Investors Service, Inc. (Moody’s), Standard & Poor’s Ratings Services (S&P), a division of The McGraw-Hill Companies, and Fitch, Inc. (Fitch) had assigned the following credit ratings to senior debt of CenterPoint Energy and certain subsidiaries:

	Moody’s		S&P		Fitch
Company/Instrument	Rating	Review (1)	Rating	Outlook(2)	Rating	Outlook(3)
CenterPoint Energy Senior Unsecured Debt	Ba1	Upgrade Review	BBB-	Positive	BBB-	Stable
CenterPoint Houston Senior Secured Debt	A3	Upgrade Review	BBB+	Positive	A-	Stable
CERC Corp. Senior Unsecured Debt	Baa3	Upgrade Review	BBB	Positive	BBB	Stable

(1) A Moody’s review for possible upgrade indicates the rating is under review for possible change in the short term, usually within 90 days.

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

(3) A “stable” outlook from Fitch encompasses a one- to two-year horizon as to the likely ratings direction.

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

A decline in credit ratings could increase borrowing costs under our $1.2 billion credit facility, CenterPoint Houston’s $289 million credit facility and CERC Corp.’s $915 million credit facility. If our credit ratings or those of CenterPoint Houston or CERC Corp. had been downgraded one notch by each of the three principal credit rating agencies from the ratings that existed at March 31, 2011, the impact on the borrowing costs under our bank 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 markets.

CERC Corp. and its subsidiaries purchase natural gas from one of their suppliers under supply agreements that contain an aggregate credit threshold of $120 million based on CERC Corp.’s S&P senior unsecured long-term debt rating of BBB. Under these agreements, CERC may need to provide collateral if the aggregate threshold is exceeded. Upgrades and downgrades from this BBB rating will increase and decrease the aggregate credit threshold accordingly.

CenterPoint Energy Services, Inc. (CES), a wholly owned subsidiary of CERC Corp. operating in our  Competitive Natural Gas Sales and Services business segment, provides comprehensive natural gas sales and services primarily to commercial and industrial customers and electric and gas utilities throughout the central and eastern United States. In order to economically hedge its exposure to natural gas prices, CES uses derivatives with provisions standard for the industry, including those pertaining to credit thresholds. Typically, the credit threshold negotiated with each counterparty defines the amount of unsecured credit that such counterparty will extend to CES. To the extent that the credit exposure that a counterparty has to CES at a particular time does not exceed that credit threshold, CES is not obligated to provide collateral. Mark-to-market exposure in excess of the credit threshold is routinely collateralized by CES. As of March 31, 2011, the amount posted as collateral aggregated approximately $72 million ($42 million of which is associated with price stabilization activities of our Natural Gas Distribution business segment). 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, 2011, unsecured credit limits extended to CES by counterparties aggregate $253 million; however, utilized credit capacity was $48 million.

37

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 $182 million as of March 31, 2011. The amount of collateral will depend on seasonal variations in transportation levels.

In September 1999, we issued Zero-Premium Exchangeable Subordinated Notes due 2029 (ZENS) having an original principal amount of $1.0 billion of which $840 million remains outstanding at March 31, 2011. Each ZENS note was originally exchangeable at the holder’s option at any time for an amount of cash equal to 95% of the market value of the reference shares of Time Warner Inc. common stock (TW Common) attributable to such note.  The number and identity of the reference shares attributable to each ZENS note are adjusted for certain corporate events. As of March 31, 2011, the reference shares for each ZENS note consisted of 0.5 share of TW Common, 0.125505 share of Time Warner Cable Inc. common stock (TWC Common) and 0.045455 share of AOL Inc. common stock (AOL Common).  If our creditworthiness were to drop such that ZENS note holders thought our liquidity was adversely affected or the market for the ZENS notes were to become illiquid, some ZENS note holders might decide to exchange their ZENS notes for cash. Funds for the payment of cash upon exchange could be obtained from the sale of the shares of TW Common, TWC Common and AOL Common that we own or from other sources. We own shares of TW Common, TWC Common and AOL Common equal to approximately 100% of the reference shares used to calculate our obligation to the holders of the ZENS notes. ZENS note exchanges result in a cash outflow because tax deferrals related to the ZENS notes and TW Common, TWC Common and AOL Common shares would typically cease when ZENS notes are exchanged or otherwise retired and TW Common, TWC Common and AOL Common shares are sold. The ultimate tax liability related to the ZENS notes continues to increase by the amount of the tax benefit realized each year, and there could be a significant cash outflow when the taxes are paid as a result of the retirement of the ZENS notes.

Cross Defaults. Under our revolving credit facility, a payment default on, or a non-payment default that permits acceleration of, any indebtedness exceeding $50 million by us or any of our significant subsidiaries will cause a default. In addition, three outstanding series of our senior notes, aggregating $750 million in principal amount as of March 31, 2011, provide that a payment default by us, CERC Corp. or CenterPoint Houston in respect of, or an acceleration of, borrowed money and certain other specified types of obligations, in the aggregate principal amount of $50 million, will cause a default. A default by CenterPoint Energy would not trigger a default under our subsidiaries’ debt instruments or bank credit facilities.

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

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 Competitive Natural Gas Sales and 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;

38

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

• the ability of GenOn and its subsidiaries to satisfy their obligations in respect of GenOn’s indemnity obligations to us and our subsidiaries or in connection with the contractual obligations to a third party pursuant to which CERC is a guarantor;

• the ability of retail electric providers (REPs), including REP subsidiaries of NRG Retail LLC and REP subsidiaries of TXU Energy Retail Company LLC, which are CenterPoint Houston’s two largest customers, 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 and against us;

• contributions to pension and postretirement benefit plans;

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

• various other risks identified in “Risk Factors” in Item 1A of Part I of our 2010 Form 10-K.

Certain Contractual Limits on Our Ability to Issue Securities and Borrow Money. CenterPoint Houston’s credit facilities limit CenterPoint Houston’s debt (excluding transition and system restoration bonds) as a percentage of its total capitalization to 65%. CERC Corp.’s bank facility and its receivables facility limit CERC’s debt as a percentage of its total capitalization to 65%. Our $1.2 billion credit facility contains a debt, excluding transition and system restoration bonds, to EBITDA covenant.  In February 2010, we amended our $1.2 billion credit facility to modify this covenant to allow for a temporary increase in debt capacity if CenterPoint Houston experiences damage from a natural disaster in its service territory that meets certain criteria. Additionally, CenterPoint Houston has contractually agreed that it will not issue additional first mortgage bonds, subject to certain exceptions.

NEW ACCOUNTING PRONOUNCEMENTS

See Note 2 to our Interim Condensed Consolidated Financial Statements for a discussion of new accounting pronouncements that affect us.

Item 3.          QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Commodity Price Risk From Non-Trading Activities

We use derivative instruments as economic hedges to offset the commodity price exposure inherent in our businesses. The stand-alone commodity risk created by these instruments, without regard to the offsetting effect of the underlying exposure these instruments are intended to hedge, is described below. We measure the commodity risk of our non-trading energy derivatives using a sensitivity analysis. The sensitivity analysis performed on our non-trading energy derivatives measures the potential loss in fair value based on a hypothetical 10% movement in energy prices. At March 31, 2011, the recorded fair value of our non-trading energy derivatives was a net liability of $59 million (before collateral). The net liability consisted of a net liability of $80 million associated with price stabilization activities of our Natural Gas Distribution business segment and a net asset of $21 million related to our Competitive Natural Gas Sales and Services business segment. Net assets or liabilities related to the price stabilization activities correspond directly with net over/under recovered gas cost liabilities or assets on the balance sheet. An increase of 10% in the market prices of energy commodities from their March 31, 2011 levels would have increased the fair value of our non-trading energy derivatives net liability by $2 million. This increase in net liabilities consists of an $8 million decrease to net liabilities associated with price stabilization activities of our Natural Gas Distribution business segment and a $10 million increase to net liabilities related to our Competitive Natural Gas Sales and Services business segment.

The above analysis of the non-trading energy derivatives utilized for commodity price risk management purposes does not include the favorable impact that the same hypothetical price movement would have on our non-derivative

39

physical purchases and sales of natural gas to which the hedges relate. Furthermore, the non-trading energy derivative portfolio is managed to complement the physical transaction portfolio, reducing overall risks within limits. Therefore, the adverse impact to the fair value of the portfolio of non-trading energy derivatives held for hedging purposes associated with the hypothetical changes in commodity prices referenced above is expected to be substantially offset by a favorable impact on the underlying hedged physical transactions.

Interest Rate Risk

As of March 31, 2011, we had outstanding long-term debt, bank loans, lease obligations and obligations under our ZENS that subject us to the risk of loss associated with movements in market interest rates.

We have no material floating-rate obligations.

At December 31, 2010 and March 31, 2011, we had outstanding fixed-rate debt (excluding indexed debt securities) aggregating $9.1 billion and $8.8 billion, respectively, in carrying amount and having a fair value of $9.9 billion and $9.5 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 (please read Note 6 to our consolidated financial statements). However, the fair value of these instruments would increase by approximately $248 million if interest rates were to decline by 10% from their levels at March 31, 2011. 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 $127 million at March 31, 2011 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 $21 million if interest rates were to decline by 10% from levels at March 31, 2011. Changes in the fair value of the derivative component, a $255 million recorded liability at March 31, 2011, 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, 2011 levels, the fair value of the derivative component liability would increase by approximately $6 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 7.2 million shares of TW Common, 1.8 million shares of TWC Common and 0.7 million shares of AOL Common, which we hold to facilitate our ability to meet our obligations under the ZENS. A decrease of 10% from the March 31, 2011 aggregate market value of these shares would result in a net loss of approximately $7 million, which would be recorded as an unrealized loss in our Condensed Statements of Consolidated Income.

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, 2011 to provide assurance that information required to be disclosed in our reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms and such information is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding disclosure.

There has been no change in our internal controls over financial reporting that occurred during the three months ended March 31, 2011 that has materially affected, or is reasonably likely to materially affect, our internal controls over financial reporting.

PART II. OTHER INFORMATION

Item 1.          LEGAL PROCEEDINGS

For a description of certain legal and regulatory proceedings affecting CenterPoint Energy, please read Notes 4 and 12(c) to our Interim Condensed Financial Statements, each of which is incorporated herein by reference. See also “Business ─ Regulation” and “─ Environmental Matters” in Item 1 and “Legal Proceedings” in Item 3 of our 2010 Form 10-K.

Item 1A.       RISK FACTORS

Other than with respect to the updated risk factor set forth below, there have been no material changes from the risk factors disclosed in our 2010 Form 10-K.

The remaining amount CenterPoint Houston will be entitled to recover in its true-up proceeding, and the timing of such recovery, will not be determined with certainty until (i) the Texas Supreme Court has acted upon various parties’ motions for rehearing of the court’s recent ruling on the appeals of the True-Up Order, (ii) the resolution of the subsequent remand proceedings before the Texas Utility Commission, and (iii) the resolution of any appeals from these proceedings.  In addition, the Texas Utility Commission’s treatment of certain deferred tax benefits in the True-Up Order has been remanded to the Texas Utility Commission at its request.  If the prior unfavorable treatment of these tax benefits is not reversed or otherwise modified in the remand proceeding, CenterPoint Energy’s results of operations, financial condition and cash flows would be adversely affected.

In March 2004, CenterPoint Houston filed its true-up application with the Texas Utility Commission, requesting recovery of $3.7 billion, excluding interest, as allowed under the Texas electric restructuring law. In December 2004, the Texas Utility Commission issued its True-Up Order allowing CenterPoint Houston to recover a true-up balance of approximately $2.3 billion, which included interest through August 31, 2004, and provided for adjustment of the amount to be recovered to include interest on the balance until recovery, along with the principal portion of additional EMCs returned to customers after August 31, 2004 and certain other adjustments.  To reflect the impact of the True-Up Order, in 2004 and 2005, CenterPoint Energy recorded a net after-tax extraordinary loss of $947 million.

Various parties, including CenterPoint Houston, appealed the True-Up Order.  These appeals were heard first by a district court in Travis County, Texas, then by the Texas Third Court of Appeals and finally by the Texas Supreme Court.  On March 18, 2011, the Texas Supreme Court issued a unanimous ruling on such appeals in which it affirmed in part and reversed in part the decision of the Texas Utility Commission and remanded the matter to the Texas Utility Commission for further proceedings.  For additional information regarding the Texas Supreme Court’s ruling, please read “Management’s Discussion and Analysis of Financial Condition and Results of Operations of CenterPoint Energy, Inc. and Subsidiaries – Executive Summary – Recent Events – Texas Supreme Court Ruling on True-Up Appeal.”

A number of parties have asked the Texas Supreme Court to reconsider its decision.  The court has 180 days from the filing of a motion for rehearing to rule on that request.  The remand to the Texas Utility Commission for further proceedings will not occur until after the court has acted on the motions for rehearing.  There is no statutory deadline by which the Texas Utility Commission must act once the case has been remanded to it; but, in accordance with the rules of the Texas Utility Commission, interest on the unsecuritized true-up balance will continue to accrue until such time as the unrecovered true-up balance is securitized or is otherwise reflected in rates.

Among the issues to be taken up by the Texas Utility Commission on the remand from the Texas Supreme Court is the proper regulatory treatment of certain deferred tax benefits.  In the True-Up Order, the Texas Utility Commission reduced CenterPoint Houston’s true-up balance by approximately $146 million, which was included in the extraordinary loss discussed above, to reflect the present value of certain deferred tax benefits associated with its former electric generation assets.  We believe that the Texas Utility Commission based its order on proposed regulations issued by the IRS in March 2003 that would have allowed utilities owning assets that were deregulated before March 4, 2003 to make a retroactive election to pass the benefits of Accumulated Deferred Investment Tax Credits (ADITC) and Excess Deferred Federal Income Taxes (EDFIT) back to customers. However, the IRS subsequently withdrew those proposed normalization regulations and, in March 2008, adopted final regulations that would not permit utilities like CenterPoint Houston to pass the tax benefits back to customers without creating

41

normalization violations. In addition, we received a Private Letter Ruling from the IRS in August 2007, prior to adoption of the final regulations, that confirmed that the Texas Utility Commission’s order reducing CenterPoint Houston’s stranded cost recovery by $146 million for ADITC and EDFIT would cause normalization violations with respect to the ADITC and EDFIT.  The Texas Utility Commission thereafter requested that this issue be remanded to that commission for further consideration, and that request was granted by the court of appeals.  CenterPoint Houston plans to seek to recover $146 million plus interest related to this issue in the remand proceedings.

If the Texas Utility Commission’s order relating to the ADITC reduction is not reversed or otherwise modified on remand so as to eliminate the normalization violation, the IRS could require CenterPoint Energy to pay an amount equal to CenterPoint Houston’s unamortized ADITC balance as of the date that the normalization violation is deemed to have occurred. In addition, the IRS could deny CenterPoint Houston the ability to elect accelerated tax depreciation benefits beginning in the taxable year that the normalization violation is deemed to have occurred. Such treatment, if required by the IRS, could have a material adverse impact on CenterPoint Energy’s results of operations, financial condition and cash flows.

The final resolution of the true-up proceedings and the ultimate amount and timing of recovery of the additional amounts authorized will depend upon the outcome of requests to the Texas Supreme Court for rehearing, future actions by the Texas Utility Commission in response to rulings by the Texas Supreme Court and the court of appeals, and any future appeals thereof.  CenterPoint Houston intends to file an application with the Texas Utility Commission for approval of a financing order authorizing the issuance of transition bonds by one or more new special purpose subsidiaries of CenterPoint Houston to securitize the recoverable amounts and certain qualified costs.  However, the timing for, and actual completion of, any transition bond offering will ultimately depend on a number of factors, including the final resolution of the true-up proceedings, the timing for the approval of a financing order and future market conditions.

Item 5.          OTHER INFORMATION

The ratio of earnings to fixed charges for the three months ended March 31, 2010 and 2011 was 2.33 and 2.48, respectively. We do not believe that the ratios for these three-month periods are necessarily indicative of the ratios for the twelve-month periods due to the seasonal nature of our business. The ratios were calculated pursuant to applicable rules of the Securities and Exchange Commission.

Exhibit 10.3

CENTERPOINT ENERGY, INC.

1991 BENEFIT RESTORATION PLAN

As Amended and Restated Effective February 25, 2011

CENTERPOINT ENERGY, INC.

1991 BENEFIT RESTORATION PLAN

(As Amended and Restated Effective February 25, 2011)

WHEREAS, CenterPoint Energy, Inc. (the “Company”), maintains the frozen CenterPoint Energy, Inc. Benefit Restoration Plan, effective as of July 1, 1991, and as thereafter amended (the “Plan”), in order to provide benefits to its eligible employees;

WHEREAS, the Plan is a “grandfathered plan” for purposes of Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”), and thus all Plan benefits were earned and vested as of December 31, 2004, along with the earnings attributable thereto (“Grandfathered Benefits”); and

WHEREAS, at all times on and after January 1, 2005, the Grandfathered Benefits, along with all earnings attributable thereto, have been (and continue to be) subject to the terms and provisions of the Plan as in effect on October 3, 2004, and no material modifications, within the meaning of Code Section 409A, have been made (in form or operation) to the Plan with respect to such benefits; and

WHEREAS, the Company desires to amend the Plan to (i) reflect that the Benefits Committee is the plan administrator and (ii) revise the Plan’s administrative claims procedures (and neither of such changes is a material modification of the Plan);

NOW, THEREFORE, the Company, having reserved the right under Paragraph 8 thereof to amend the Plan, does hereby amend and restate the Plan, effective as of February 25, 2011, to reflect the prior amendment to the Plan and the changes desired above, as follows:

-1-

CENTERPOINT ENERGY, INC.

1991 BENEFIT RESTORATION PLAN

(As Amended and Restated Effective February 25, 2011)

1.           Name.  The name of the Plan is the “CenterPoint Energy, Inc. 1991 Benefit Restoration Plan” (the “Plan”), as amended and restated effective February 25, 2011, as set forth herein, and as the same may hereafter be amended from time to time.  As of January 1, 2008, the Plan is frozen and (i) no new participants shall be permitted, and (ii) no benefits shall be earned or vested (other than earnings on benefits that were earned and vested as of December 31, 2004) under the Plan after December 31, 2007; unvested benefit accruals as of December 31, 2004 (along with earnings attributable thereto) were spun-off from the Plan, effective as of January 1, 2008, into, and shall be provided under, the CenterPoint Energy Benefit Restoration Plan (and the Plan shall have no contractual, legal or other obligation with respect to such spun-off benefits on and after January 1, 2008).

2.           Purpose. Section 415 of the Internal Revenue Code of 1986, as amended ("Section 415"), imposes limitations on the amount of retirement benefits which may be paid to certain Employees of the Company and its participating Subsidiaries under the Retirement Plan.  Effective January 1, 1989, Section 401(a)(17) of the Internal Revenue Code of 1986, as amended ("Section 401(a)(17)"), limits to $200,000 (indexed annually) the annual compensation of each participating Employee which may be taken into account in computing benefits under the Retirement Plan for any Plan Year.  In addition, the Retirement Plan excludes from the definition of "Compensation" for purposes of computing benefits (a) any salary deferrals under the CenterPoint Energy, Inc. Deferred Compensation Plan (the "Deferred Compensation Plan") and (b) any annual awards earned under the CenterPoint Energy, Inc. Executive Incentive Compensation Plan (the "EICP").  The principal purposes of the Plan are to provide additional benefits to those Employees whose retirement benefits under the Retirement Plan are reduced, curtailed or otherwise limited as a result of the limitations imposed by Section 415 and Section 401(a)(17), and to provide supplemental retirement benefits to those Employees selected by the Committee whose retirement benefits under the Retirement Plan are affected by the exclusion of certain amounts under the Deferred Compensation Plan and EICP.

3.           Participants.

a.           Retirement Plan Restoration Benefits. All full-time, salaried officers or highly-compensated Employees of the Company or any of its adopting Subsidiaries shall

-2-

be eligible to participate in the "Retirement Plan Restoration Benefit" described in Paragraph 4.  Each eligible Employee shall become a Restoration Participant from and after June 1, 1985 if as of such date one of the limitations imposed by Section 415 or Section 401(a)(17) applies to his benefits under the Retirement Plan.  Each other eligible Employee shall become a Restoration Participant from and after the first January lst after June 1, 1985 as of which one of the limitations imposed by Section 415 or Section 401(a)(17) applies to his benefits under the Retirement Plan.

b.           Supplemental Retirement Benefits. The Committee shall select Employees eligible to participate in the "Supplemental Retirement Benefit" described in Paragraph 5 from full-time, salaried officers or other highly-compensated Employees of the Company or any adopting Subsidiary.  Once selected as a Supplemental Participant, an Employee shall continue to be a Supplemental Participant as long as he continues to be an Employee of the Company or of a participating Subsidiary unless the Committee determines that his participation shall cease as of the end of any calendar year in which notice of such discontinuance of participation is delivered in writing to the Supplemental Participant by the Committee.

4.           Retirement Plan Restoration Benefit. When a Restoration Participant's retirement benefit commences or a death benefit payable with respect to a Restoration Participant commences under the Retirement Plan, the Company will calculate a benefit equal to the excess of the amount of the retirement benefit or death benefit, as the case may be, which would have been payable under the Retirement Plan but for the limitations imposed by Section 415 and Section 401(a)(17) over the amount of the retirement benefit or death benefit actually payable under the Retirement Plan, which excess is referred to herein as the "Retirement Plan Restoration Benefit."  The Company shall pay a Retirement Plan Restoration Benefit to such Restoration Participant or such other persons, at such times and in such manner as the Retirement Plan benefit is payable pursuant to the terms of the Retirement Plan; provided, however, that (i) the commencement of payment of any Retirement Plan Restoration Benefit attributable to an Early Pension or a Deferred Vested Pension under the Retirement Plan may be delayed beyond the earliest date the Restoration Participant could elect to commence receiving any such benefit under the Retirement Plan only if the Committee approves such delayed commencement date of such Retirement Plan Restoration Benefit, and (ii) the Company may in its sole discretion determine to convert the payment of the Retirement Plan Restoration Benefit into an actuarially equivalent lump sum payment, as determined by the Committee, with the advice of the actuary

-3-

for the Retirement Plan, employing those actuarial assumptions as are then employed in converting Retirement Plan benefits from one form to another.

5.           Supplemental Retirement Benefit. When a Supplemental Participant's retirement benefit commences or a death benefit payable in respect of the Supplemental Participant commences under the Retirement Plan, the Company will calculate a benefit under the Plan equal to the amount that would have been payable under the Retirement Plan (without the limitations of Section 415 and Section 401(a)(17)) if the definition of "Compensation" under the Retirement Plan was amended to include (i) any amounts deferred under the Deferred Compensation Plan at the time of deferral and (ii) any annual awards earned by the Supplemental Participant under EICP in the December of the calendar year for which the award was earned. For purposes of clause (ii) above, if the Supplemental Participant is awarded an annual EICP award after his termination of Service, such award shall be considered as Compensation in the December immediately preceding his termination if and only if it results in a greater benefit payable to the Supplemental Participant under the Plan; any increase in benefits shall be retroactive to the initial commencement of benefits.  The excess of the amount of such benefit over the total amount actually payable under the Retirement Plan and any Retirement Plan Restoration Benefit payable under the Plan is referred to herein as the "Supplemental Retirement Benefit."  The Company shall pay a Supplemental Retirement Benefit to such Supplemental Participant or such other persons at such times and in such manner as the Retirement Plan benefit is payable pursuant to the terms of the Retirement Plan; provided, however, that (i) the commencement of payment of any Supplemental Retirement Benefit attributable to an Early Pension or a Deferred Vested Pension under the Retirement Plan may be delayed beyond the earliest date the Supplemental Participant could elect to commence receiving any such benefit under the Retirement Plan only if the Committee approves such delayed commencement date of such Supplemental Retirement Benefit, and (ii) the Company may in its sole discretion determine to convert the payment of the Supplemental Retirement Benefit into an actuarially equivalent lump sum payment, as determined by the Committee, with the advice of the actuary for the Retirement Plan, employing those actuarial assumptions as are then employed in converting Retirement Plan benefits from one form to another.

6.           Contractual Obligation of Company. The benefits described in the Plan are contractual obligations of the Company to pay compensation for services, and shall constitute a liability to the Participants and/or their beneficiaries in accordance with the terms hereof. The payment of such benefits shall be made from the general funds of the Company.  No special or

-4-

separate fund need be established and no segregation of assets need be made to assure the payment of such benefits.  No Participant shall have any interest in any particular asset of the Company by virtue of his rights under the Plan. To the extent that any person acquires a right to receive payments from the Company under the Plan, such right shall be no greater than the right of an unsecured general creditor of the Company.

7.           Administration. The Plan shall be administered, construed and interpreted by the Committee.  The determinations by the Committee of the Employees who are eligible to be Participants in the Plan, the selection of Participants from eligible Employees, the amounts of their benefits under the Plan, and the construction and interpretation by the Committee of any provision of the Plan, shall be final, conclusive and binding upon all parties including the Company, its shareholders and its employees.  No member of the Committee shall be liable for any act done or determination made in good faith.  All expenses of administering the Plan shall be borne by the Company.

8.           Amendment or Termination of the Plan. The Board of Directors may terminate the Plan at any time.  The Board of Directors may amend or modify the Plan from time to time in any respect.  No such termination or amendment by the Board of Directors shall divest a Participant of any benefit which had previously accrued to him or which had previously become payable to him under the Plan unless the Participant agrees in writing to such divestment.

9.           Non-Alienation of Benefits. Except by mutual agreement between the Company and the Participant, any benefit which shall be payable under the Plan shall not be subject in any manner to anticipation, alienation, sale, transfer, assignment, pledge, encumbrance, or charge, and any attempt at such shall be void, and any such benefit shall not in any way be subject to the debts, contract, liabilities, engagements, or torts of the person who shall be entitled to such benefit, nor shall it be subject to attachment or legal process for or against such person.

10.           No Employment Rights. The receipt of benefits under the Plan shall not give a Participant any right to continued employment by the Company and its Subsidiaries; the right to terminate employment of any Participant, with or without cause, is specifically reserved by the Company.

11.           Definitions. For purposes of the Plan, the following definitions shall be applicable:

-5-

a.           "Board of Directors" shall mean the Board of Directors of CenterPoint Energy, Inc.

b.           "Committee" shall mean the Benefits Committee of the Company or such other committee designated as such by the Board of Directors.

c.           "Company" shall mean CenterPoint Energy, Inc., any successor thereto, and/or any subsidiaries adopting the Plan with approval of the Board of Directors.

d.           "Employee" shall mean any person who is regularly employed on a salary basis by the Company or by a Subsidiary, including, but not limited to, any employee who is also an officer or director of the Company or of a Subsidiary.

e.           "Participant" shall mean any Employee who is entitled to a benefit under the provisions of Paragraph 4 and/or Paragraph 5 of the Plan.

f.           "Restoration Participant" shall mean any Employee who is entitled to a benefit under the provisions of Paragraph 4 of the Plan.

g.           "Retirement Plan" shall mean the CenterPoint Energy, Inc. Retirement Plan, as amended from time to time.

h.           "Subsidiary" shall mean a company 50 percent or more of whose voting stock is owned (directly or through another Subsidiary) by the Company and which is an Employer under the Retirement Plan.

i.           "Supplemental Participant" shall mean any Employee who is entitled to a benefit under the provisions of Paragraph 5 of the Plan.

12.           Effective Date. The effective date of this amended and restated Plan shall be February 25, 2011. Any benefits payable under the Plan to a Participant whose employment terminated prior to July 1, 1991 shall be governed by the terms of the Plan as in effect on the date of his termination.  The Plan shall continue until terminated by the Board of Directors as provided in paragraph 8.

13.           Applicable Law.  The Plan shall be construed, administered and governed in all respects in accordance with ERISA and other applicable federal law and, to the extent not preempted by federal law, in accordance with the laws of the State of Texas.

14.           Claims and Review Procedures.

a.           Claims Procedure.  If any person believes he is entitled to any rights or benefits under the Plan, such person may file a claim in writing with the Committee.  If any such claim is wholly or partially denied, the Committee will notify such person of its decision in writing.  Such notification will contain (i) specific reasons for the denial, (ii)

-6-

specific reference to pertinent Plan provisions, (iii) a description of any additional material or information necessary for such person to perfect such claim and an explanation of why such material or information is necessary, and (iv) information as to the steps to be taken if the person wishes to submit a request for review, the time limits applicable to such procedures, and a statement of the person’s rights following an adverse benefit determination on review, including a statement of his right to file a lawsuit under ERISA if the claim is denied on appeal.  Such notification will be given within 90 days after the claim is received by the Committee (or within 180 days, if special circumstances require an extension of time for processing the claim, and if written notice of such extension and circumstances is given to such person within the initial 90-day period).

b.           Claim Review Procedure.  Within 60 days after the date on which a person receives a notice of denial, such person or his duly authorized representative (“Applicant”) may (i) file a written request with the Committee for a review of his denied claim; (ii) review pertinent documents; and (iii) submit issues and comments in writing.  The Committee shall render a decision no later than the date of its regularly scheduled meeting next following receipt of a request for review, except that a decision may be rendered no later than the second such meeting if the request is received within 30 days of the first meeting.  The Applicant may request a formal hearing before the Committee which the Committee may grant in its discretion.  Notwithstanding the foregoing, under special circumstances that require an extension of time for rendering a decision (including, but not limited to, the need to hold a hearing), the decision may be rendered not later than the date of the third regularly scheduled Committee meeting following the receipt of the request for review.  If such an extension is required, the Applicant will be advised in writing before the extension begins.  If the claim is denied in whole or part, such notice, which shall be in a manner calculated to be understood by the person receiving such notice, shall include (i) the specific reasons for the decision, (ii) the specific references to the pertinent Plan provisions on which the decision is based, (iii) that the Applicant is entitled to receive, upon request and free of charge, reasonable access to, and copies of, all documents, records, and other information relevant to the claim for benefits, and (iv) a statement of the Applicant’s right to file a lawsuit under ERISA.  Benefits under the Plan will only be paid if the Committee decides, in its discretion, that an Applicant is entitled to them.

-7-

c.           Exhaustion of Administrative Remedies.  The decision of the Committee on review of the claim denial shall be binding on all parties when the Applicant has exhausted the claims procedure under this Section.  Moreover, no action at law or in equity shall be brought to recover benefits under the Plan prior to the date the Applicant has exhausted the administrative remedies under this Section.  Applicants must submit all claims within two years beginning on the later of 1) the date a payment was made, 2) the date of the first in a series of periodic payments, or 3) the date on which a claim is incurred.
