Below is a list of terms that are common to our industry and used throughout this document:
     
/d
  = per day
Bbl
  = barrels
BBtu
  = billion British thermal units
Bcf
  = billion cubic feet
GW
  = gigawatts
GWh
  = gigawatt hours
LNG
  = liquefied natural gas
MBbls
  = thousand barrels
Mcf
  = thousand cubic feet
Mcfe
  = thousand cubic feet of natural gas equivalents
MMBbls
  = million barrels
MMBtu
  = million British thermal units
MMcf
  = million cubic feet
MMcfe
  = million cubic feet of natural gas equivalents
NGL
  = natural gas liquids
TBtu
  = trillion British thermal units
     When we refer to oil and natural gas in “equivalents,” we are doing so to compare quantities of oil with quantities of natural gas or to express these different commodities in a common unit. In calculating equivalents, we use a generally recognized standard in which one Bbl of oil is equal to six Mcf of natural gas. Also, when we refer to cubic feet measurements, all measurements are at a pressure of 14.73 pounds per square inch.
     When we refer to “us”, “we”, “our”, “ours”, “the company” or “El Paso”, we are describing El Paso Corporation and/or our subsidiaries.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)
1. Basis of Presentation and Significant Accounting Policies
Basis of Presentation
     We prepared this Quarterly Report on Form 10-Q under the rules and regulations of the United States Securities and Exchange Commission (SEC). As an interim period filing presented using a condensed format, it does not include all of the disclosures required by U.S. generally accepted accounting principles (GAAP), and should be read along with our 2010 Annual Report on Form 10-K. The financial statements as of March 31, 2011, and for the quarters ended March 31, 2011 and 2010, are unaudited. The condensed consolidated balance sheet as of December 31, 2010, was derived from the audited balance sheet filed in our 2010 Annual Report on Form 10-K. In our opinion, we have made adjustments, all of which are of a normal, recurring nature to fairly present our interim period results. Our financial statements for prior periods include reclassifications that were made to conform to the current year presentation, none of which impacted our reported net income (loss) or stockholders’ equity. Additionally, our statement of cash flows for the quarter ended March 31, 2010, reflects a decrease in both net cash provided by operating activities and net cash used in investing activities related to the timing of certain capital expenditures which was considered immaterial to our 2010 consolidated financial statements. Due to the seasonal nature of our businesses, information for interim periods may not be indicative of our operating results for the entire year. Our disclosures in this Form 10-Q are an update to those provided in our 2010 Annual Report on Form 10-K.
Significant Accounting Policies
     There were no changes in the significant accounting policies described in our 2010 Annual Report on Form 10-K and no significant accounting pronouncements issued but not yet adopted as of March 31, 2011.
2. Other Income, Net
     The following are the components of other income and other expense for the quarters ended March 31:
                 
    2011     2010  
    (In millions)  
Other Income
               
Allowance for equity funds used during construction
  $ 97     $ 50  
Other
    7       14  
 
           
Total
    104       64  
 
           
 
               
Other Expense

    5       4  
 
           
Total
    5       4  
 
           
Other income, net
  $ 99     $ 60  
 
           
     Allowance for Equity Funds Used During Construction. As allowed by the Federal Energy Regulatory Commission (FERC), we capitalize a pre-tax carrying cost on equity funds related to the construction of long-lived assets in our FERC regulated business and reflect this amount as an increase in the cost of the asset on our balance sheet. We calculate this amount using the most recent FERC approved equity rate of return. These amounts are recovered over the depreciable lives of the long-lived assets to which they relate.

3. Income Taxes
     Income taxes for the quarters ended March 31 were as follows:
                 
    2011   2010
    (In millions, except rates)
Income tax expense
  $ 19     $ 186  
Effective tax rate
    12 %     31 %
     Effective Tax Rate. We compute interim period income taxes by applying an anticipated annual effective tax rate to our year-to-date income or loss, except for significant unusual or infrequently occurring items, which are recorded in the period the item occurs. Changes in tax laws or rates are recorded in the period of enactment. Our effective tax rate is affected by items such as income attributable to nontaxable noncontrolling interests, dividend exclusions on earnings from unconsolidated affiliates where we anticipate receiving dividends, the effect of state income taxes (net of federal income tax effects), and the effect of foreign income which can be taxed at different rates.
     During the first quarter of 2011, our effective tax rate was lower than the statutory rate primarily due to the benefit to our anticipated annual effective tax rate of income attributable to nontaxable noncontrolling interests and dividend exclusions on earnings from unconsolidated affiliates where we anticipate receiving dividends. In addition, our effective tax rate for the first quarter of 2011 was favorably impacted by the resolution of several tax matters and earned state tax credits. During the first quarter of 2010, our effective tax rate was lower than the statutory rate primarily due to income attributable to nontaxable noncontrolling interests partially offset by $18 million of additional deferred income tax expense from healthcare legislation enacted in March 2010 which reduces the tax deduction for retiree prescription drug expenses to the extent they are reimbursed under the Medicare subsidy program.
4. Earnings Per Share

     We exclude potentially dilutive securities from the determination of diluted earnings per share (as well as their related income statement impacts) when their impact on net income attributable to El Paso Corporation per common share is antidilutive. Our potentially dilutive securities for the periods presented consist of employee stock options, restricted stock, convertible preferred stock and trust preferred securities. In March 2011, we converted our preferred stock to common stock as further described in Note 9. For the quarters ended March 31, 2011 and 2010, certain of our employee stock options were antidilutive. Additionally, for the quarter ended March 31, 2011, our trust preferred securities were antidilutive.

     As of March 31, 2011 and December 31, 2010, the carrying amounts of cash and cash equivalents, accounts receivable, accounts payable and short-term financing obligations represent fair value because of the short-term nature of these instruments. The carrying amounts of our restricted cash and noncurrent receivables approximate their fair value based on the nature of their interest rates and our assessment of the ability to recover these amounts. We estimated the fair value of our long-term financing obligations based on quoted market prices for the same or similar issues, including consideration of our credit risk related to those instruments.
     Our derivative financial instruments are further described in our 2010 Annual Report on Form 10-K and below:
    Production-Related Commodity Based Derivatives. As of March 31, 2011 and December 31, 2010, we have production-related derivatives (oil and natural gas swaps, collars, basis swaps and option contracts) to mitigate a portion of our commodity price risk and stabilize cash flows associated with forecasted sales of natural gas and oil production on 253 TBtu and 283 TBtu of natural gas and 15,777 MBbl and 12,240 MBbl of oil. None of these contracts are designated as accounting hedges.
 
    Other Commodity-Based Derivatives. As of March 31, 2011 and December 31, 2010, in our Marketing segment we have forwards, swaps and options contracts related to long-term natural gas and power. These contracts, the longest of which extends into 2019, include (i) obligations to sell natural gas to power plants ranging from 12,550 MMBtu/d to 95,000 MMBtu/d and (ii) an obligation to swap locational differences in power prices between three power plants in the Pennsylvania-New Jersey-Maryland (PJM) eastern region with the PJM west hub on approximately 1,700 to 3,700 GWh, to provide annually approximately 1,700 GWh of power and approximately 71 GW of installed capacity in the PJM power pool. We have entered into contracts to economically mitigate our exposure to commodity price changes and locational price differences on substantially all of these natural gas and power volumes. None of these derivatives are designated as accounting hedges.
 
    Interest Rate Derivatives. We have long-term debt with variable interest rates that exposes us to changes in market-based interest rates. As of March 31, 2011 and December 31, 2010, we had interest rate swaps, that are designated as cash flow hedges that effectively convert the interest rate on approximately $1.3 billion of debt from a floating LIBOR interest rate to a fixed interest rate. Approximately $1.1 billion of the debt hedged as of March 31, 2011 relates to debt associated with our Ruby pipeline project that begin accruing interest on July 1, 2011 and have termination dates ranging from June 2013 to June 2017. These termination dates correspond to the estimated principal outstanding on the Ruby debt over the term of these swaps. For a further discussion of our Ruby financing, see Note 6.
     We also have long-term debt with fixed interest rates that exposes us to paying higher than market rates should interest rates decline. We use interest rate swaps designated as fair value hedges to protect the value of certain of these debt instruments by converting the fixed amounts of interest due under the debt agreements to variable interest payments. We record changes in the fair value of these derivatives in interest expense which is offset by changes in the fair value of the related hedged items. As of March 31, 2011 and December 31, 2010, these interest rate swaps converted the interest rate on approximately $184 million of debt from a fixed rate to a variable rate of LIBOR plus 4.18%.

     Fair Value Measurement. We separate the fair values of our financial instruments into three levels (Levels 1, 2 and 3) based on our assessment of the availability of observable market data and the significance of non-observable data used to determine fair value. Our assessment and classification of an instrument within a level can change over time based on the maturity or liquidity of the instrument. During the quarter ended March 31, 2011, there have been no changes to the inputs and valuation techniques used to measure fair value, the types of instruments, or the levels in which they are classified. Our marketable securities in non-qualified compensation plans and other are reflected at fair value on our balance sheets as other long-term assets, other current liabilities and other long-term liabilities. We net our derivative assets and liabilities for counterparties where we have a legal right of offset and classify our derivatives as either current or non-current assets or liabilities based on their anticipated settlement date. At March 31, 2011 and December 31, 2010, cash collateral held was not material. The following table presents the fair value of our financial instruments at March 31, 2011 and December 31, 2010 (in millions).

     On certain derivative contracts recorded as assets in the table above, we are exposed to the risk that our counterparties may not perform or post the required collateral. Based on our assessment of counterparty risk in light of the collateral our counterparties have posted with us (primarily in the form of letters of credit), we have determined that our exposure is primarily related to our production-related derivatives and is limited to nine financial institutions, each of which has a current Standard & Poor’s credit rating of A or better.

     Subsequent to March 31, 2011, our overall debt has increased by approximately $500 million due to incremental borrowings under our revolving credit facilities. This increase was partially offset by a reduction in letters of credit issued under these facilities related to our Ruby pipeline project.
     Repurchase of Senior Notes. In March 2011, we repurchased $148 million of notes and recorded a loss on debt extinguishment of approximately $41 million. In April 2011, we repurchased an additional $153 million of notes and will record a loss of approximately $19 million in the second quarter of 2011.
     Credit Facilities/Letters of Credit. We have various credit facilities in place which allow us to borrow funds or issue letters of credit. During the first quarter of 2011, we increased the total letter of credit capacity under certain existing letter of credit facilities by $125 million with a weighted average fixed facility fee of 1.95 percent and maturities ranging from March 2013 to September 2014. As of March 31, 2011, the aggregate amount outstanding under all of our credit facilities was $0.2 billion (excluding $0.4 billion outstanding on the EPPOC $750 million revolving credit facility) and $1.1 billion of letters of credit and surety bonds issued, including $0.4 billion related to our price risk management activities. Our total available capacity under all of our facilities was approximately $2.6 billion as of March 31, 2011 (not including capacity available under the EPPOC $750 million revolving credit facility and our Ruby project financing).
     The availability of borrowings under our credit agreements and our ability to incur additional debt is subject to various financial and non-financial covenants and restrictions. There have been no significant changes to our restrictive covenants, and as of March 31, 2011, we were in compliance with all of our debt covenants. For a further discussion of our credit facilities and restrictive covenants, see our 2010 Annual Report on Form 10-K.
     Ruby Pipeline Financing. During 2010, we entered into a seven-year amortizing $1.5 billion financing facility for our Ruby pipeline project (see Note 11) that requires principal payments at various dates through June 2017. As of March 31, 2011, we have utilized substantially all of the capacity under this facility. Our initial interest rate on amounts borrowed is LIBOR plus 3 percent which increases to LIBOR plus 3.25 percent for years three and four, and to LIBOR plus 3.75 percent for years five through seven assuming we refinance $700 million of the facility by the end of year four. If we do not refinance $700 million by the end of year four, the rate will be LIBOR plus 4.25 percent for years five through seven. In conjunction with entering into this facility, we entered into interest rate

swaps that begin in July 2011 and convert the floating LIBOR interest rate to fixed interest rates on approximately $1.1 billion of total borrowings under this agreement.
     We have provided a contingent completion and cost-overrun guarantee to the Ruby lenders; however, upon the Ruby pipeline project becoming operational and making certain permitting representations, the project financing will become non-recourse to us. Pursuant to the cost overrun guarantee to the Ruby lenders, as of March 31, 2011, we have $350 million outstanding in letters of credit to cover anticipated cost overruns. If additional cost overruns are forecasted and approved by the lender’s engineer in subsequent months, additional collateral may be required to be issued pursuant to the Ruby financing agreements.
7. Commitments and Contingencies
Legal Proceedings
     Cash Balance Plan Lawsuit. In December 2004, a purported class action lawsuit entitled Tomlinson, et al.v. El Paso Corporation and El Paso Corporation Pension Plan was filed in U.S. District Court for Denver, Colorado. The lawsuit alleges various violations of the Employee Retirement Income Security Act (ERISA) and the Age Discrimination in Employment Act as a result of our change from a final average earnings formula pension plan to a cash balance pension plan. In 2010, a trial court dismissed all of the claims in this matter. The dismissal of the case has been appealed.
     Price Reporting Litigation. Beginning in 2003, several lawsuits were filed against El Paso Marketing L.P. (EPM) alleging that El Paso, EPM and other energy companies conspired to manipulate the price of natural gas by providing false price information to industry trade publications that published gas indices. While some of the cases have been settled or dismissed, several of the cases are in various stages of pre-trial or appellate proceedings as further described in our 2010 Annual report on Form 10-K. Although damages in excess of $140 million have been alleged in total against all defendants in one of the remaining lawsuits where a damage number is provided, there remains significant uncertainty regarding the validity of the causes of action, the damages asserted and the level of damages, if any, that may be allocated to us. Therefore, our costs and legal exposure related to the remaining outstanding lawsuits and claims are not currently determinable.
     MTBE. Certain of our subsidiaries used, produced, sold or distributed methyl tertiary-butyl ether (MTBE) as a gasoline additive. Various lawsuits were filed throughout the U.S. regarding the potential impact of MTBE on water supplies. The lawsuits have been brought by different parties, including state attorney generals, water districts and individual water companies seeking different remedies against us and many other defendants, including remedial activities, damages, attorneys’ fees and costs. These cases were initially consolidated for pre-trial purposes in multi-district litigation (MDL) in the U.S. District Court for the Southern District of New York. Several cases were later remanded to state court. Eighty-seven of the cases have been settled or dismissed, with all of the settlements being substantially funded by insurance. We have twelve remaining lawsuits, which consist of ten cases that are pending in the MDL and two cases that are pending in state courts. Of these remaining lawsuits, it is likely that our insurers will assert denial of coverage on nine of the most-recently filed lawsuits. Although damages in excess of two billion dollars have been alleged in total against all defendants in some of the remaining cases, based upon discovery conducted to date, our share of the relevant markets upon which alleged damages have been historically allocated among individual defendants is relatively small. In addition, there remains significant uncertainty regarding the validity of the causes of action, the damages asserted and the level of damages, if any, that may be allocated to us as well as availability of insurance coverages. Therefore, our costs and legal exposure related to the remaining lawsuits are not currently determinable.
     In addition to the above proceedings, we and our subsidiaries and affiliates are named defendants in numerous lawsuits and governmental proceedings and claims that arise in the ordinary course of our business. For each of these matters, we evaluate the merits of the case or claim, our exposure to the matter, possible legal or settlement strategies and the likelihood of an unfavorable outcome. If we determine that an unfavorable outcome is probable and can be estimated, we establish the necessary accruals. While the outcome of these matters, including those discussed above, cannot be predicted with certainty, and there are still uncertainties related to the costs we may incur, based upon our evaluation and experience to date, we believe we have established appropriate reserves for these matters. It is possible, however, that new information or future developments could require us to reassess our potential exposure related to these matters and adjust our accruals accordingly, and these adjustments could be

material. As of March 31, 2011, we had approximately $50 million accrued, which has not been reduced by $3 million of related insurance receivables, for all of our outstanding legal proceedings.
Rates and Regulatory Matters
     EPNG Rate Case. In April 2010, the FERC approved an uncontested partial offer of settlement which increased EPNG’s base tariff rates, effective January 1, 2009. As part of the settlement, EPNG made refunds to its customers in 2010. The settlement resolved all but four issues in the proceeding. In January 2011, the Presiding Administrative Law Judge issued a decision that for the most part found against EPNG on the four issues. EPNG will appeal those decisions to the FERC and may also seek review of any of the FERC’s decisions to the U.S. Court of Appeals. Although the final outcome is not currently determinable, we believe our accruals established for this matter are adequate based on the expected final outcome.
     In September 2010, EPNG filed a new rate case with the FERC proposing an increase in its base tariff rates as permitted under the settlement of the previous rate case. In October 2010, the FERC issued an order accepting and suspending the effective date of the proposed rates to April 1, 2011, subject to refund, the outcome of a hearing and other proceedings. At this time, the outcome of this matter is not determinable.
     TGP Rate Case. In November 2010, TGP filed a rate case with the FERC proposing an increase in its base tariff rates, including a proposed change in its rate structure. In December 2010, the FERC issued an order accepting and suspending the effective date of the proposed rates to June 1, 2011, subject to refund, the outcome of a hearing and other proceedings. At this time, the outcome of this matter is not determinable.
     CIG Rate Case. In February 2011, the FERC approved an amendment of CIG’s 2006 rate case settlement allowing the effective date of a required new rate case to be moved to December 1, 2011. In April 2011, CIG filed a second petition to amend the effective date of a required new rate case to be moved to February 1, 2012 to allow CIG and its shippers the opportunity to reach a settlement of the rate proceeding before it is formally filed with the FERC. The FERC has not ruled on that petition. At this time, the outcome of the pre-filing settlement negotiations and the outcome of the upcoming general rate case, in the event pre-filing settlement cannot be reached, are uncertain.
Environmental Matters
     We are subject to federal, state and local laws and regulations governing environmental quality and pollution control. These laws and regulations require us to remove or remedy the effect of the disposal or release of specified substances at current and former operating sites. At March 31, 2011, our accrual was approximately $168 million for environmental matters, which has not been reduced by $19 million for amounts to be paid directly under government sponsored programs or through contractual arrangements with third parties. Our accrual includes approximately $165 million for expected remediation costs and associated onsite, offsite and groundwater technical studies and approximately $3 million for related environmental legal costs.
     Our estimates of potential liability range from approximately $168 million to approximately $352 million. Our recorded environmental liabilities reflect our current estimates of amounts we will expend on remediation projects in various stages of completion. However, depending on the stage of completion or assessment, the ultimate extent of contamination or remediation required may not be known. As additional assessments occur or remediation efforts continue, we may incur additional liabilities. By type of site, our reserves are based on the following estimates of reasonably possible outcomes:

     Superfund Matters. Included in our recorded environmental liabilities are projects where we have received notice that we have been designated or could be designated, as a Potentially Responsible Party (PRP) under the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA), commonly known as

14


Table of Contents

Superfund, or state equivalents for 30 active sites. Liability under the federal CERCLA statute may be joint and several, meaning that we could be required to pay in excess of our pro rata share of remediation costs. We consider the financial strength of other PRPs in estimating our liabilities. Accruals for these issues are included in the previously indicated estimates for Superfund sites.
     For 2011, we estimate that our total remediation expenditures will be approximately $40 million, most of which will be expended under government directed clean-up plans. In addition, we expect to make capital expenditures for environmental matters of approximately $27 million in the aggregate for the remainder of 2011 through 2015, including capital expenditures associated with the impact of the Environmental Protection Agency (EPA) rule on emissions of hazardous air pollutants from reciprocating internal combustion engines which are subject to regulations with which we have to be in compliance by October 2013.
     It is possible that new information or future developments could require us to reassess our potential exposure related to environmental matters. We may incur significant costs and liabilities in order to comply with existing environmental laws and regulations. It is also possible that other developments, such as increasingly strict environmental laws, regulations and orders of regulatory agencies, as well as claims for damages to property and the environment or injuries to employees and other persons resulting from our current or past operations, could result in substantial costs and liabilities in the future. As this information becomes available, or other relevant developments occur, we will adjust our accrual amounts accordingly. While there are still uncertainties related to the ultimate costs we may incur, based upon our evaluation and experience to date, we believe our reserves are adequate.
Guarantees and Other Contractual Commitments
     Guarantees and Indemnifications. We have guarantees and indemnifications with a maximum stated value of approximately $0.8 billion, primarily related to indemnification arrangements associated with the sale of ANR Pipeline Company in 2007 and certain legacy assets. These amounts exclude guarantees for which we have issued related letters of credit discussed in Note 6. We are unable to estimate a maximum exposure of our guarantee and indemnification agreements that do not provide for limits on the amount of future payments due to the uncertainty of these exposures.
     As of March 31, 2011, we have recorded obligations of $17 million related to our guarantee and indemnification arrangements. We believe that our guarantee and indemnification agreements for which we have not recorded a liability are not probable of resulting in future losses based on our assessment of the nature of the guarantee, the financial condition of the guaranteed party and the period of time that the guarantee has been outstanding, among other considerations.
     For a further discussion of our guarantees, indemnifications, purchase obligations, and other commercial commitments see our 2010 Annual Report on Form 10-K.

9. Equity and Preferred Stock of Subsidiaries
     Convertible Perpetual Preferred Stock. On March 11, 2011, we exercised our mandatory conversion right related to our $750 million of convertible perpetual preferred stock. Upon conversion, holders of our convertible preferred stock received approximately 57.9 million shares of common stock (approximately 77.2295 shares of El Paso common stock for each share of preferred stock converted).
     Common and Preferred Stock Dividends. The table below shows the amount of dividends paid and declared (in millions, except per share amount):
                 
    Common Stock   Convertible Preferred Stock
    ($0.01/Share)   (4.99%/Year)
Amount paid through March 31, 2011
  $ 7     $ 9  
Amount paid in April 2011
  $ 7        
Declared in April 2011:
               
Date of declaration
  April 1, 2011      
Payable to shareholders on record
  June 3, 2011      
Date payable
  July 1, 2011      
     Dividends on our common stock and convertible preferred stock are treated as a reduction of additional paid-in-capital since we currently have an accumulated deficit. We expect dividends paid in 2011 on our common stock and preferred stock will be taxable to our stockholders because we anticipate that these dividends will be paid out of current or accumulated earnings and profits for tax purposes. Our ability to pay dividends can be impacted by certain restrictions as further described in our 2010 Annual Report on Form 10-K.
     Noncontrolling Interest in EPB. We are the general partner of EPB, a master limited partnership (MLP) formed in 2007. As of March 31, 2011, we hold a 2 percent general partner interest and a 45 percent limited partner interest in the partnership. In accordance with its partnership agreement, EPB is obligated to make quarterly distributions of available cash to its unitholders. We receive our share of these cash distributions through our limited partner ownership interest, general partner interest, and incentive distribution rights (IDRs) we are entitled to as the general partner. Prior to February 15, 2011, we held subordinated units in EPB. Upon payment of the quarterly cash distribution for the fourth quarter of 2010, the financial tests required for the conversion of subordinated units into common units were satisfied. As a result, our subordinated units were converted on February 15, 2011 into common units on a one-for-one basis effective January 3, 2011.
     During the first quarter of 2011, EPB issued 13.8 million common units for $457 million in conjunction with the contribution of an additional 25 percent ownership interest in Southern Natural Gas (SNG). While we still control EPB, as a result of this unit issuance our total ownership percentage in EPB (including our general partner interest) decreased from approximately 51 percent to 47 percent. Our consolidated statement of equity for the quarter ended March 31, 2011 reflects the issuance of the EPB common units as an increase of $287 million to noncontrolling interests and $170 million to El Paso Corporation’s additional paid-in capital. Our net income attributable to El Paso Corporation, together with the increase in El Paso Corporation’s additional paid-in capital for the quarter ended March 31, 2011 totaled $232 million.
     To the extent that the consideration for the sales of assets to EPB is not in the form of additional equity in EPB, our interest in our assets becomes diluted over time. However our economic interest will benefit from the receipt of incentive distributions in accordance with the partnership agreement.
     Our IDRs provide for the receipt of an increasing portion of quarterly distributions based on the level of distribution to all unitholders. We can elect to relinquish the right to receive incentive distribution payments and reset, at higher levels, the minimum quarterly distribution amount and cash target distribution levels upon which the incentive distribution payments would be set. We are currently entitled to receive the maximum level of incentive distributions.

     Preferred Stock of Subsidiaries. During the quarter ended March 31, 2011, our partner on our Ruby pipeline project, Global Infrastructure Partners (GIP), contributed an additional $30 million and as of March 31, 2011 had contributed $700 million, including approximately $555 million for a convertible preferred interest in Ruby Pipeline Holding Company, L.L.C. (Ruby) and $145 million for a convertible preferred equity interest in Cheyenne Plains Gas Pipeline Company, L.L.C. (Cheyenne Plains). GIP earns a 15 percent dividend on its preferred interests in Cheyenne Plains. GIP will earn a 13 percent return on its convertible preferred interests in Ruby beginning on the earlier of the date the pipeline project is placed in service or August 2011. We paid preferred dividends of $5 million on GIP’s preferred interest in Cheyenne Plains for the quarters ended March 31, 2011 and 2010. Also, for the quarter ended March 31, 2011, we recorded $17 million related to the return on GIP’s preferred interest in Ruby. Both the preferred dividends and the return on GIP’s preferred interests are reflected in net income attributable to noncontrolling interests on our income statement. GIP’s preferred interests in Cheyenne Plains and Ruby are classified between liabilities and equity on our balance sheet. For a further discussion of the Ruby transaction, see Note 11.

10. Business Segment Information
     As of March 31, 2011, our business consists of the following segments: Pipelines, Exploration and Production, and Marketing. We also have other business and corporate activities. Our segments are strategic business units that provide a variety of energy products and services. They are managed separately as each segment requires different technology and marketing strategies. A further discussion of each segment follows.
     Pipelines. Our Pipelines segment provides natural gas transmission, storage, and related services, primarily in the U.S. As of March 31, 2011, we conducted our activities primarily through eight wholly or majority owned interstate pipeline systems and equity interests in two transmission systems. In addition to the storage capacity in our wholly and majority owned pipelines systems, we also own or have interests in three underground natural gas storage facilities and two LNG terminal facilities, one of which is under construction.
     Exploration and Production. Our Exploration and Production segment is engaged in the exploration for and the acquisition, development and production of oil, natural gas and NGL, in the U.S., Brazil and Egypt.
     Marketing. Our Marketing segment markets on behalf of our Exploration and Production segment and manages the price risks associated with our oil and natural gas production as well as manages our remaining legacy trading portfolio.
     Other. Our other activities include our corporate general and administrative functions, midstream operations and other miscellaneous businesses.
     Beginning January 1, 2011, we use segment earnings before interest expense and income taxes (Segment EBIT) as a measure to assess the operating results and effectiveness of our business segments. We believe Segment EBIT is useful to our investors because it allows them to use the same performance measure analyzed internally by our management to evaluate the performance of our businesses and investments without regard to the manner in which they are financed or our capital structure. Segment EBIT is defined as net income (loss) adjusted for interest and debt expense and income taxes. It does not reflect a reduction for any amounts attributable to noncontrolling interests. Segment EBIT may not be comparable to measurements used by other companies. Additionally, Segment EBIT should be considered in conjunction with net income (loss), income (loss) before income taxes and other performance measures such as operating income or operating cash flows. Our 2010 amounts have been conformed to reflect our current performance measure.
     Below is a reconciliation of our Segment EBIT to our net income for the periods ended March 31:

11. Variable Interest Entities and Accounts Receivable Sales Programs
     Ruby/Cheyenne Plains. As of March 31, 2011 GIP, our partner in the Ruby pipeline project, had contributed approximately $700 million in exchange for convertible preferred equity interests (see Note 9) in Ruby and Cheyenne Plains. We consolidate Ruby and Cheyenne Plains as variable interest entities as we are the primary beneficiary of these entities that own the Ruby pipeline project and the Cheyenne Plains pipeline. GIP’s contributions are classified between liabilities and equity on our balance sheet since the events that require redemption of the preferred interests are not entirely within our control and are not certain to occur. GIP will hold its interest in Cheyenne Plains until certain conditions are satisfied including placing the Ruby pipeline project in service by the end of November 2011. Should this not occur, GIP has the option to convert its Cheyenne Plains preferred interest to a common interest and/or be repaid in cash for its remaining investments in Cheyenne Plains and Ruby including a 15 percent return on its investments in Cheyenne Plains and Ruby. Our obligation to repay these amounts is secured by our equity interests in Ruby, Cheyenne Plains, and approximately 50 million common units we own in EPB. If all conditions to closing are satisfied or waived, GIP would own a 50 percent preferred equity interest in Ruby and all ownership in Cheyenne Plains would be transferred back to us. Additionally, GIP has the right to convert its preferred equity in Ruby to common equity in Ruby at any time.
     Accounts Receivable Sales Program. We participate in accounts receivable sales programs where several of our pipeline subsidiaries sell receivables in their entirety to a third-party financial institution (through wholly-owned special purpose entities). The sale of these accounts receivable (which are short-term assets that generally settle within 60 days) qualify for sale accounting. The third party financial institution involved in these accounts receivable sales programs acquires interests in various financial assets and issues commercial paper to fund those acquisitions. We do not consolidate the third party financial institution because we do not have the power to control, direct, or exert significant influence over its overall activities since our receivables do not comprise a significant portion of its operations.
     In connection with our accounts receivable sales, we receive a portion of the sales proceeds up front and receive an additional amount upon the collection of the underlying receivables (which we refer to as a deferred purchase price). Our ability to recover the deferred purchase price is based solely on the collection of the underlying receivables. The table below contains information related to our accounts receivable sales program.

     The deferred purchase price related to the accounts receivable sold is reflected as other accounts receivable on our balance sheet. Because the cash received up front and the deferred purchase price relate to the sale or ultimate collection of the underlying receivables, and are not subject to significant other risks given their short term nature, we reflect all cash flows under the accounts receivable sales programs as operating cash flows on our statement of cash flows. Under the accounts receivable sales programs, we service the underlying receivables for a fee. The fair value of these servicing agreements, as well as the fees earned, were not material to our financial statements for the quarters ended March 31, 2011 and 2010.

     We received distributions and dividends from our unconsolidated affiliates of approximately $12 million and $15 million for the quarters ended March 31, 2011 and 2010. Our transactions with unconsolidated affiliates were not material during the quarters ended March 31, 2011 and 2010.
     Other Investment-Related Matters. We currently have outstanding disputes and other matters related to an investment in two Brazilian power plant facilities (Manaus/Rio Negro) formerly owned by us. We have filed lawsuits to collect amounts due to us (approximately $71 million of Brazilian reais-denominated accounts receivable) by the plants’ power purchaser, which are also guaranteed by the purchaser’s parent, Eletrobras, Brazil’s state-owned utility. The power utility that purchased the power from these facilities and its parent have asserted counterclaims that would largely offset our accounts receivable. We have not established an allowance against the receivables owed and have accrued what we believe is an appropriate amount in relation to the asserted counterclaims.
     Our project companies that previously owned the Manaus and Rio Negro power plants have also been assessed approximately $82 million of Brazilian reais-denominated ICMS taxes by the Brazilian taxing authorities for payments received by the companies from the plants’ power purchaser from 1999 to 2001. By agreement, the power purchaser must indemnify our project companies for these ICMS taxes, along with related interest and penalties, and has therefore been defending the projects against this lawsuit. In order to prevent further collection efforts by the tax authorities for this matter, security must be provided for the potential tax liability to the court’s satisfaction. The tax authorities and court rejected certain assets pledged by the power purchaser, and during the third quarter of 2010 the tax courts blocked certain of El Paso’s bank accounts associated with the Rio Negro power plant in order to obtain this security. The power purchaser has appealed the court’s decision. The power purchaser’s parent subsequently offered to pledge other assets acceptable to the tax authorities and a decision by the court whether to approve these assets is pending. If the court approves, then the power purchaser will ask the court to vacate any orders encumbering our bank accounts and other assets. Until this tax matter is resolved, our ability to collect amounts due to us from the power purchaser could be impacted. Any potential taxes owed by the Manaus and Rio Negro project companies are also guaranteed by the purchaser’s parent. Based on our assessment, we have not established any accruals for this matter.

     The ultimate resolution of the matters discussed above is unknown at this time, and adverse developments related to either our ability to collect amounts due to us or related to these disputes and claims could require us to record additional losses in the future.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations
     The information contained in Item 2 updates, and should be read in conjunction with, information disclosed in our 2010 Annual Report on Form 10-K, and the financial statements and notes presented in Item 1 of this Quarterly Report on Form 10-Q.
Overview and Outlook
     During the quarter ended March 31, 2011, our Segment EBIT was $395 million, compared with $848 million for the same period in 2010. In 2011, Pipeline Segment EBIT increased slightly over 2010 to approximately $499 million for the quarter benefiting from expansion projects placed in service in 2010 and from the allowance for funds used during construction (AFUDC) related to pipeline expansion projects not yet in service (including Ruby); partially offset by lower reservation revenues on our EPNG system. Our Exploration and Production Segment EBIT decreased by approximately $421 million largely due to mark-to-market impacts on our financial derivatives, despite increases in production volumes quarter over quarter. During the first quarter of 2011, we also incurred approximately $41 million in losses associated with the repurchase of debt. We continue to work towards completion of our backlog of pipeline expansion projects, and in April, the Florida Gas Transmission (FGT) Phase VIII Expansion was placed in service on time and on budget. In our exploration and production business, our continued 2011 capital focus is in our Haynesville, Altamont, Eagle Ford, and Wolfcamp areas which provide us greater exposure to both oil and natural gas liquids opportunities. Finally, in our midstream business, we continue to seek out opportunities that focus on synergies with our pipeline and/or exploration and production businesses, funding these projects in a manner that is consistent with our long-term goal of improving our balance sheet, including the evaluation of additional partnership opportunities on our projects. For the remainder of 2011, we expect that our pipeline and exploration and production operations will provide a strong base of earnings and operating cash flow. Our operating and financial results and outlook are further discussed in the individual segment results that follow.
     From a liquidity perspective, as of March 31, 2011, we had approximately $2.8 billion of available liquidity (exclusive of cash and credit facility capacity of EPB and Ruby). During the first quarter of 2011, we generated operating cash flow of approximately $0.5 billion and have spent approximately $1.1 billion primarily on our pipeline and exploration and production capital programs. Our remaining 2011 capital expenditures are approximately $2.1 billion and remaining debt maturities are approximately $0.5 billion, which we will repay as they mature. Among other financing activities, during the first quarter our MLP also issued approximately $0.5 billion in common units. As further described in Liquidity and Capital Resources, we believe we are well positioned in 2011 to meet our obligations as well as continue with our efforts to strengthen our balance sheet. We will continue to assess and take further actions where prudent to meet our long-term objectives and capital requirements and to address any changes in the financial and commodity markets and our businesses.

Segment Results
     As of March 31, 2011, our business consists of the following segments: Pipelines, Exploration and Production, and Marketing. We also have other business and corporate activities that include midstream and other miscellaneous businesses. Our segments are managed separately, provide a variety of energy products and services, and require different technology and marketing strategies.
     Beginning January 1, 2011, we use segment earnings before interest expense and income taxes (Segment EBIT) as a measure to assess the operating results and effectiveness of our business segments. We believe Segment EBIT is useful to our investors because it allows them to use the same performance measure analyzed internally by our management to evaluate the performance of our businesses and investments without regard to the manner in which they are financed or our capital structure. Segment EBIT is defined as net income (loss) adjusted for interest and debt expense and income taxes. It does not reflect a reduction for any amounts attributable to noncontrolling interests. Segment EBIT may not be comparable to measurements used by other companies. Additionally, Segment EBIT should be considered in conjunction with net income (loss), income (loss) before income taxes and other performance measures such as operating income or operating cash flows. Our 2010 amounts have been conformed to reflect our current performance measure.

Our Pipelines Segment EBIT for the quarter ended March 31, 2011 increased 10 percent from the first quarter of 2010 benefiting primarily from several expansion projects placed in service in 2010 and an increase in AFUDC related to pipeline expansion projects not yet in service, including our Ruby project, offset by a decline in reservation revenues from our EPNG system due to lower demand and firm transportation commitments. Below are the operating results for our Pipelines segment as well as a discussion of factors impacting Segment EBIT for the quarters ended March 31, 2011 compared with 2010, or that could potentially impact Segment EBIT in future periods.

(1)   Consists of individually insignificant items on several of our pipeline systems.
     Expansions. During 2011, we benefited from increased reservation revenues due to placing the WIC System expansion, Phase A of both the SLNG Elba Expansion III and Elba Express Pipeline expansion, the CIG Raton 2010 expansion, and Phase I of the SNG South System III expansion in service. In April 2011, the FGT Phase VIII Expansion was placed in service on time and on budget. We own a 50 percent interest in Citrus, which owns the FGT system.
     Additionally, in the first quarter of 2011, we began construction on the TGP 300 Line pipeline and the remaining compressor facilities. We expect the project to be placed in service in November 2011.
     We capitalize a carrying cost (AFUDC) on funds related to our construction of long-lived assets. During the quarter ended March 31, 2011, we benefited from an increase in other income of approximately $49 million associated with the equity portion of AFUDC on our expansion projects. This increase was primarily due to our Ruby pipeline project. In April 2011, Ruby filed an amendment of its certificate requesting an increase in maximum initial recourse rates to reflect the new estimate of expected construction costs. Additionally, Ruby proposed in its filing to limit total AFUDC accruals to the total amounts included in the original certificate order. The FERC has not yet issued an order on the proposed amendment of the certificate.
     Until placed in service, our Ruby project will be consolidated in our financial results. We currently fund and reflect 100 percent of the capital cost of this project, including cost overruns, in our results which reflect higher AFUDC capitalized due to project delays. Shortly after completion of this project, subject to meeting certain conditions, we anticipate reflecting Ruby in our financial statements as an equity investment in which we own 50 percent. Once deconsolidated, we will be required to evaluate our investment in Ruby for impairment. Based on increased costs and delays in project completion which impact the net book value of our investment, depending on the fair value at the time of evaluation, we may be required to write-down a portion of our investment in Ruby. Additionally, we will reflect equity earnings from Ruby in Segment EBIT after the impact of interest expense and preferred interests. As such, our Segment EBIT contribution from Ruby will decline once the pipeline is placed in service. Our level of earnings will depend on the level of contracted customer capacity and our ability to market unsubscribed firm capacity. Currently, approximately 1.1 Bcf/d of the total design capacity of 1.5 Bcf/d on our Ruby pipeline project is subscribed. In the near term, based on current market conditions, we do not expect additional long-term firm capacity subscriptions.

     Reservation and Usage Revenues. During the quarter ended March 31, 2011, our reservation and usage revenues decreased primarily on our EPNG system due to the nonrenewal of expiring contracts as a result of reduced basis differentials and lower throughput volumes as a result of storage withdrawals in California and increased competition in its California and Arizona market areas. The impact of these items unfavorably impacted our Segment EBIT by $21 million when compared with the prior period.
     Gas Not Used in Operations and Revaluations. During the quarter ended March 31, 2011, our Segment EBIT, primarily on our TGP system, was favorably impacted by $16 million due to higher volumes and realized prices on operational and other gas sales, partially offset by lower retained fuel volumes in excess of fuel used in operations and lower prices of approximately $11 million, as compared with the same period in 2010. Our future earnings may be impacted positively or negatively depending on changes in throughput and fluctuations in natural gas prices. We continue to explore options to minimize the price volatility associated with these operational pipeline activities. As a result of the TGP rate case filed with the FERC which proposes a change in its rate structure. The percentage of our revenues on TGP derived from reservation charges may increase relative to revenues derived from excess fuel recoveries.
     Operating and General and Administrative Expenses. During the quarter ended March 31, 2011, our operating and general and administrative expenses were higher compared to the same period in 2010 primarily due to higher benefits, payroll, and contractor costs.
     Asset Write Downs. During the first quarter of 2010, we recorded an impairment of approximately $10 million primarily related to our decision not to continue with a storage project due to market conditions.
     Other Regulatory Matters. Our pipeline systems periodically file for changes in their rates, which are subject to approval by the FERC. Changes in rates and other tariff provisions resulting from these regulatory proceedings have the potential to positively or negatively impact our profitability. Currently, several of our pipelines have projected upcoming rate actions with anticipated effective dates in 2011 as further described in Item 1, Financial Statements, Note 7 and below.
     EPNG Rate Case. In September 2010, EPNG filed a new rate case proposing an increase in its base tariff rates which would increase revenue by approximately $100 million annually over previously effective tariff rates. In October 2010, the FERC issued an order accepting and suspending the effective date of the proposed rates to April 1, 2011, subject to refund, the outcome of a hearing and other proceedings. At this time, the outcome of this matter is not determinable.
     TGP Rate Case. In November 2010, TGP filed a rate case with the FERC proposing an increase in its base tariff rates which would increase reservation revenues by approximately $200 million annually over previously effective tariff rates. In December 2010, the FERC issued an order accepting and suspending the effective date of the proposed rates to June 1, 2011, subject to refund, the outcome of a hearing and other proceedings. At this time, the outcome of this matter is not determinable.
     CIG Rate Case. In February 2011, the FERC approved an amendment of CIG’s 2006 rate case settlement allowing the effective date of a required new rate case to be moved to December 1, 2011. In April 2011, CIG filed a second petition to amend the effective date of a required new rate case to be moved to February 1, 2012 to allow CIG and its shippers the opportunity to reach a settlement of the rate proceeding before it is formally filed with the FERC. The FERC has not ruled on that petition. At this time, the outcome of the pre-filing settlement negotiations and the outcome of the upcoming general rate case, in the event pre-filing settlement cannot be reached, are uncertain.

Exploration and Production Segment
Overview and Strategy
     Our Exploration and Production segment conducts our oil and natural gas exploration and production activities. The success of this segment is driven by the ability to locate and develop economic oil and natural gas reserves and extract those reserves at the lowest possible production and administrative costs. Accordingly, we manage this business with the goal of creating value through disciplined capital allocation, cost control and portfolio management. Our strategy focuses on building and applying competencies in assets with repeatable programs, executing to improve capital and expense efficiency, and maximizing returns by adding assets and inventory that match our competencies and divesting assets that do not. For a further discussion of our business strategy in our exploration and production business, see our 2010 Annual Report on Form 10-K.
     Our profitability and performance is impacted by, among other factors, changes in commodity prices and industry-wide changes in the cost of drilling and oilfield services which impact our daily production, operating and capital costs. Additionally we may be impacted by the effect of hurricanes and other weather events, or the effects of domestic or international regulatory or other actions in response to events outside of our control (e.g. oil spills). To the extent possible, we attempt to mitigate certain of these risks through actions, such as entering into contractual arrangements to control costs and entering into derivative contracts to reduce the financial impact of downward commodity price movements.
     In 2011, our Gulf Coast division was renamed the Southern division, and we made minor changes to the properties contained within our various domestic operating divisions. Divisional amounts for prior periods have been adjusted to reflect these changes. In March 2011, we also announced that we would develop our Eagle Ford program without a partner.
Significant Operational Factors Affecting the Quarter Ended March 31, 2011
     Production. Our average daily production for the three months ended March 31, 2011 was 821 MMcfe/d, including 63 MMcfe/d from our equity interest in the production of Four Star. Below is an analysis of our production by division for the quarters ended March 31:
                 
    2011   2010
    MMcfe/d
United States
               
Central
    406       331

Four Star
    63       64  
 
               
Total Combined
    821       781  
 
               
Central division — Our 2011 Central division production volumes continued to increase as a result of our successful drilling programs in the Haynesville shale. At March 31, 2011, we had 74 operated wells and our total production was approximately 258 MMcfe/d.
Western division — Our 2011 Western division production volumes increased primarily due to our successful drilling programs in Altamont offset by natural declines in the Rockies.
Southern division — Our 2011 Southern division production volumes decreased primarily due to natural declines and lower levels of drilling activity in the Texas Gulf Coast and Gulf of Mexico areas. In this division, we continue to focus on increasing our Eagle Ford shale activity, where in 2011 we have successfully drilled 10 additional wells, for a total of 31 wells. These wells are located principally in the liquids rich area. We also continue to assess our Wolfcamp shale area.

Brazil — Our 2011 production in Brazil increased due to production from our Camarupim Field. We continue to work with Petrobras in this field where a fourth well is expected to begin production in late second quarter of 2011. We also continue the process of obtaining regulatory and environmental approvals in the Pinauna Field in the Camamu Basin that are required in order to enter the next phase of development.
     Cash Operating Costs. We monitor cash operating costs required to produce our oil and natural gas production volumes. Cash operating costs is a non-GAAP measure calculated on a per Mcfe basis and includes total operating expenses less depreciation, depletion and amortization expense, ceiling test and other impairment charges, transportation costs and cost of products. Cash operating costs per unit is a valuable measure of operating performance and efficiency for our Exploration and Production segment. During the quarter ended March 31, 2011, cash operating costs per unit decreased to $1.85/Mcfe as compared to $1.88/Mcfe during the same period in 2010, due to higher production volumes.
     Capital Expenditures. Our total oil and natural gas capital expenditures were $352 million for the quarter ended March 31, 2011, of which $348 million were domestic capital expenditures.
     Outlook for 2011. Our guidance related to capital expenditures, production volumes, cash operating costs, and depreciation, depletion and amortization is consistent with those outlined in our 2010 Annual Report on Form 10-K. We continue to review our capital program in light of changes in commodity prices, our decision not to seek a partner for our Eagle Ford shale acreage, the results of our core programs, and potential acquisitions and divestitures.
Price Risk Management Activities
     We enter into derivative contracts on our oil and natural gas production to stabilize cash flows and reduce the risk and financial impact of downward commodity price movements on commodity sales. Because we apply mark-to-market accounting on our financial derivative contracts and because we do not hedge the entirety of our price risks, this strategy only partially reduces our commodity price exposure. Our reported results of operations, financial position and cash flows can be impacted significantly by commodity price movements from period to period. Adjustments to our strategy and the decision to enter into new positions or to alter existing positions are made based on the goals of the overall company. During the first quarter of 2011, approximately 80 percent of our natural gas production and 100 percent of our crude oil production were economically hedged at average floor prices of $5.81 per MMBtu and $85.99 per barrel, respectively.

     Physical sales. Physical sales represent accrual-based commodity sales transactions with customers. During the first quarter of 2011 our revenues from physical sales decreased compared to the same quarter of 2010. Natural gas prices continued to decline, although focus on our core programs in the Haynesville and Eagle Ford shale increased oil and natural gas production volumes in the first quarter of 2011.
     Realized and unrealized gains (losses) on financial derivatives. During the first quarter of 2011, we recognized net losses of $109 million compared to net gains of $253 million during the same period in 2010. Gains or losses each period are due to changes in the fair value of our derivative contracts based on forward commodity prices relative to the prices in the underlying contracts.
     Depreciation, depletion and amortization expense. During the first quarter of 2011, our depreciation, depletion and amortization expense increased as a result of a higher depletion rate and higher production volumes compared with the same quarter in 2010. In 2009, we recorded ceiling test charges which significantly lowered our depletion rate. We expect the upward trend in our depletion rate relative to prior periods to continue as we focus our capital on developing our core programs.
     General and administrative expenses. During the first quarter of 2011, our general and administrative expenses increased compared to the same period in 2010, due to severance costs related to an office closure, offset by lower labor-related costs. The impact of these severance costs was approximately $5 million, or $0.07 per Mcfe on total cash operating costs.
     Production costs. Our production costs increased during the first quarter of 2011 as compared to the same period in 2010 primarily due to higher lease operating expenses and higher production taxes as a result of higher production volumes. Production costs per unit were relatively flat when comparing these periods.

     Ceiling test charges. We are required to conduct quarterly impairment tests of our capitalized costs in each of our full cost pools. During the first quarter of 2010, we recorded a non-cash ceiling test charge in our Egyptian full cost pool of $2 million as a result of the relinquishment of approximately 30 percent of our acreage in the South Mariut block.
     Other. Our equity earnings from Four Star decreased by $2 million during the first quarter of 2011 as compared to the same period in 2010 primarily due to the impact of lower natural gas prices. Four Star’s results are more sensitive to changes in natural gas prices as production volumes are predominantly natural gas.

Marketing Segment
     Our Marketing segment’s primary focus is to market our Exploration and Production segment’s oil and natural gas production and to manage El Paso’s overall price risk. In addition, we continue to manage and liquidate certain legacy contracts. All of our remaining contracts are subject to counterparty credit and non-performance risks while our remaining mark-to-market contracts are also subject to interest rate exposure. Our contracts are described below and in further detail in our 2010 Annual Report on Form 10-K.
     Natural gas transportation-related contracts. The impact of these accrual-based contracts is based on our ability to use or remarket the contracted pipeline capacity and the amount of production from our Exploration and Production segment. As of March 31, 2011, these contracts require us to pay demand charges of $31 million for the remainder of 2011 and an average of $40 million per year between 2012 and 2015.
     Legacy natural gas and power contracts. As of March 31, 2011, these contracts include (i) long-term accrual based supply contracts, including transportation expenses, that obligate us to deliver natural gas to specified power plants and (ii) power contracts in the PJM region through 2016, which we mark-to-market in our results. These contracts are expected to have minimal future impact on our earnings as we have entered into offsetting positions that eliminate the price risks associated with our PJM power contracts and substantially offset the fixed price exposure related to our natural gas supply contracts.
Operating Results
     Overview. Our overall operating results and analysis for our Marketing segment during each of the quarters ended March 31 are as follows:

     Our first quarter 2011 results were primarily driven by a $15 million loss related to settlements on an affiliated fuel supply agreement. Our first quarter 2010 results were primarily driven by an $18 million mark-to-market gain on our legacy power contracts due to changes in the locational power prices used to value the contracts.

Other Activities
     Our other activities include our corporate general and administrative functions, our midstream operations and other miscellaneous businesses.
     Midstream. As of March 31, 2011, our midstream operations consist primarily of wholly-owned assets in the Haynesville area in north Louisiana and the Eagle Ford area in south Texas, in addition to an equity investment in a joint venture that owns the Altamont gathering and processing system and plant in the Uintah basin of Utah. The joint venture is currently working to expand the Altamont system, and we and our joint venture partner have each committed to make up to $500 million of future capital contributions to the joint venture for additional midstream projects to be acquired or developed by the joint venture. Our midstream business is also evaluating several larger scale projects in the Marcellus shale in Pennsylvania, the Eagle Ford area, and opportunities in emerging shale plays in the Rockies, west Texas and the northeast United States. For the full year 2011, we expect to make capital expenditures and equity investments totaling approximately $100 million related to the midstream projects discussed above.
     The following is a summary of significant items impacting the Segment EBIT in our other activities for the quarters ended March 31:
                 
Income (Loss)   2011     2010

Total Segment EBIT
  $ (59 )   $ (11 )
 
           
     Loss on Debt Extinguishment. During the first quarter of 2011, we recorded a total loss of $41 million in conjunction with repurchasing $148 million of our notes due in 2012 through 2025 for cash. In April 2011, we repurchased an additional $153 million of our notes which will result in recording a loss of approximately $19 million in the second quarter of 2011. We will continue to evaluate repurchasing debt as conditions warrant for the remainder of 2011 which may result in additional losses.
     Environmental, Legal and Other Reserves. We have a number of pending litigation and environmental matters and reserves related to our historical business operations that affect our results. Adverse rulings or unfavorable outcomes or settlements against us related to these matters may continue to impact our future results.
Interest and Debt Expense
     Our interest and debt expense decreased during the quarter ended March 31, 2011 as compared to the same period in 2010 primarily due to the exchange or repurchase of debt as described below. This decrease was offset by the 2010 issuance of approximately $1.3 billion of EPPOC notes having rates ranging from 4.1 percent to 7.5 percent and increases in Ruby pipeline project financing, net of higher capitalized AFUDC related to debt, primarily associated with the Ruby pipeline project.
     In 2010 and 2011, we exchanged or repurchased approximately $1.2 billion of debt having rates ranging from 7 percent to 12 percent as further described in our 2010 Annual Report on Form 10-K and in Note 6. Interest savings associated with these liability management transactions have been offset by interest costs on new borrowings.

Liquidity and Capital Resources
     Available Liquidity Update and Liquidity Outlook for 2011. As of March 31, 2011, we had approximately $2.8 billion of available liquidity (exclusive of cash and credit facility capacity of EPB and Ruby). The increase in our available liquidity during the first quarter of 2011 was primarily the result of issuing additional MLP common units in conjunction with contributing additional ownership interests in SNG to our MLP. During the first quarter of 2011, among other activities, we continued to repurchase notes and also borrowed the remaining amount under our seven-year amortizing $1.5 billion Ruby financing facility to support the construction of the Ruby pipeline project.
     Our planned 2011 capital expenditures will allow us to place a substantial portion of our pipeline backlog in service by the end of 2011 while continuing to support our exploration and production strategy. Our cash capital expenditures for the quarter ended March 31, 2011, and the amount of cash we expect to spend for the remainder of 2011 to grow and maintain our businesses are as follows:
                         
    Quarter Ended     2011

(1)   Our pipeline growth capital expenditures reflect 100 percent of capital related to our Ruby project. We have a partner on this project as described below.
 
(2)   Includes $100 million related to our midstream business.
     GIP, our 50 percent partner in the Ruby pipeline project, has provided approximately $700 million to support the Ruby project. Our obligation to repay these amounts, if required, is secured by our equity interests in Ruby, Cheyenne Plains, and approximately 50 million common units we own in our MLP. We have also provided a contingent completion and cost-overrun guarantee to Ruby lenders; however, upon the Ruby pipeline project becoming operational and making certain permitting representations, the project financing will become non-recourse to us. Pursuant to the cost overrun guarantee to the Ruby lenders, as of March 31, 2011, we have $350 million outstanding in letters of credit to cover anticipated cost overruns. If additional cost overruns are forecasted and approved by the lender’s engineer in subsequent months, additional collateral may be required to be issued pursuant to the Ruby financing agreements. For a further description of this project and our agreement with GIP, see our 2010 Annual Report on Form 10-K and Note 11.
     We expect our current liquidity sources and operating cash flow to be sufficient to fund our estimated 2011 capital program. For the remainder of 2011, we also have remaining debt maturities of approximately $500 million which we will repay as they mature. As a result of our current available liquidity, hedging program in place on our oil and natural gas production, and planned future actions (including continuing with our MLP drop down strategy as markets permit), we believe we are well positioned to meet our obligations as well as continue with our efforts to strengthen our balance sheet. We will continue to assess and take further actions where prudent to meet our long-term objectives and capital requirements as well as address further changes in the financial and commodity markets.
     There are a number of factors that could impact our plans, including our ability to access the financial markets to fund our long-term capital needs if the financial markets are restricted, or a further decline in commodity prices. If these events occur, additional adjustments to our plan and outlook may be required, including reductions in our discretionary capital program, reductions in operating and general and administrative expenses, obtaining secured financing arrangements, seeking additional partners for other growth projects or the sale of additional non-core assets, all of which could impact our financial and operating performance.
     Overview of Cash Flow Activities. During the first quarter of 2011, we generated operating cash flow of approximately $0.5 billion primarily from our pipeline and exploration and production operations. We also generated approximately $1.3 billion in the first quarter as a result of Ruby and other consolidated project financings, as well as the issuance of MLP common units. We used cash flow generated from these operating and financing activities to fund our capital programs and to make net repayments under our various credit facilities and other

Item 4. Controls and Procedures
Evaluation of Disclosure Controls and Procedures
     As of March 31, 2011, we carried out an evaluation under the supervision and with the participation of our management, including our Chief Executive Officer (CEO) and our Chief Financial Officer (CFO), as to the effectiveness, design and operation of our disclosure controls and procedures. This evaluation considered the various processes carried out under the direction of our disclosure committee in an effort to ensure that information required to be disclosed in the U.S. Securities and Exchange Commission reports we file or submit under the Securities Exchange Act of 1934, as amended (Exchange Act) is accurate, complete and timely. Our management, including our CEO and our CFO, does not expect that our disclosure controls and procedures or our internal controls will prevent and/or detect all errors and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within our company have been detected. Our disclosure controls and procedures are designed to provide reasonable assurance of achieving their objectives and our CEO and CFO concluded that our disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) were effective as of March 31, 2011.
Changes in Internal Control over Financial Reporting
     There were no changes in our internal control over financial reporting during the first quarter of 2011 that have materially affected or are reasonably likely to materially affect our internal control over financial reporting.

Item 1A. Risk Factors
CAUTIONARY STATEMENTS FOR PURPOSES OF THE “SAFE HARBOR” PROVISIONS
OF THE PRIVATE SECURITIES LITIGATION REFORM ACT OF 1995
     We have made statements in this document that constitute forward-looking statements, as that term is defined in the Private Securities Litigation Reform Act of 1995. Forward-looking statements include information concerning possible or assumed future results of operations. The words “believe,” “expect,” “estimate,” “anticipate” and similar expressions will generally identify forward-looking statements. These statements may relate to information or assumptions about:
    earnings per share;
 
    capital and other expenditures;
 
    dividends;
 
    financing plans;
 
    capital structure;
 
    liquidity and cash flow;
 
    pending legal proceedings, claims and governmental proceedings, including environmental matters;
 
    future economic and operating performance;
 
    operating income;
 
    management’s plans; and
 
    goals and objectives for future operations.
     Forward-looking statements are subject to risks and uncertainties. While we believe the assumptions or bases underlying the forward-looking statements are reasonable and are made in good faith, we caution that assumed facts or bases almost always vary from actual results, and these variances can be material, depending upon the circumstances. We cannot assure you that the statements of expectation or belief contained in our forward-looking statements will result or be achieved or accomplished. Important factors that could cause actual results to differ materially from estimates or projections contained in our forward-looking statements are described in our 2010 Annual Report on Form 10-K under Part I, Item 1A, Risk Factors. There have been no material changes in our risk factors since that report.
