Subsequent to the ETE Merger, the Company amended certain of its OPEB plans to prospectively restrict participation in the plans for certain active employees. The plan amendments resulted in the plans becoming currently over-funded and, accordingly, the Company recorded a gross pre-tax curtailment gain of $70 million, $59 million of which is subject to refund to customers; thus, the net curtailment gain recognition was $11 million.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Description of the Business

OPERATIONS AND ORGANIZATION:

Business Operations

Panhandle Eastern Pipe Line Company, LP (“we,” “us,” the “Company” and “Panhandle”) is primarily engaged in the interstate transportation and storage of natural gas and also provides LNG terminalling and regasification services and is subject to the rules and regulations of the FERC. The Company’s entities include the following:


•	PEPL, an indirect wholly-owned subsidiary of Southern Union, which is an indirect wholly-owned subsidiary of ETP;


•	Trunkline, a direct wholly-owned subsidiary of PEPL;


•	Sea Robin, an indirect wholly-owned subsidiary of PEPL;


•	LNG Holdings, an indirect wholly-owned subsidiary of PEPL;


•	Trunkline LNG, a direct wholly-owned subsidiary of LNG Holdings; and


•	Southwest Gas, a direct wholly-owned subsidiary of PEPL.

The Company’s operations consist of interstate pipelines that transport natural gas from the Gulf of Mexico, South Texas and the panhandle regions of Texas and Oklahoma to major U.S. markets in the Midwest and Great Lakes region, as well as owned underground storage capacity. The Company also owns and operates an LNG import terminal located on Louisiana’s Gulf Coast, as well as an above ground LNG storage facility.

Southern Union Panhandle LLC serves as the general partner of PEPL and owns a 1% general partnership interest in PEPL. PEPL Holdings, a wholly-owned subsidiary of Southern Union, owns a 99% limited partnership interest in PEPL and a 100% membership interest in Southern Union Panhandle LLC.

See Note 2 for information related to the completion of the Holdco Transaction.

Preparation of Interim Financial Statements

The accompanying condensed consolidated balance sheet as of December 31, 2012, which has been derived from audited financial statements, and the unaudited interim condensed consolidated financial statements and notes thereto of the Company as of September 30, 2013 and for the three and nine month periods ended September 30, 2013 and 2012, have been prepared in accordance with GAAP for interim condensed consolidated financial information and pursuant to the rules and regulations of the SEC. Accordingly, they do not include all of the information and footnotes required by GAAP for complete consolidated financial statements. However, management believes that the disclosures made are adequate to make the information not misleading. The results of operations for interim periods are not necessarily indicative of the results to be expected for a full year due to the seasonal nature of the Company’s operations.

The accompanying unaudited interim condensed consolidated financial statements reflect adjustments that are, in the opinion of management, necessary for a fair statement of results for the interim period. The unaudited interim condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto of Panhandle Eastern Pipe Line Company, LP presented in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012, as filed with the SEC on March 1, 2013.

Holdco Transaction	9 Months Ended
Holdco Transaction	Sep. 30, 2013
Business Combinations [Abstract]
ETE Merger and ETP Merger	HOLDCO TRANSACTION: On April 30, 2013, ETP acquired ETE’s 60% interest in Holdco, the entity formed by ETP and ETE in 2012 to own the equity interests in Southern Union and Sunoco. As a result of this transaction, ETP now owns 100% of Holdco. ETP controlled Holdco prior to this transaction; therefore, the transaction did not constitute a change of control.

- Definition

The entire disclosure for a business combination (or series of individually immaterial business combinations) completed during the period, including background, timing, and recognized assets and liabilities. The disclosure may include leverage buyout transactions (as applicable).

Related Party Transactions

RELATED PARTY TRANSACTIONS:

Accounts receivable from related companies reflected on the condensed consolidated balance sheets primarily related to services provided for Southern Union, ETE, ETP and other affiliates. Accounts payable to related companies reflected on the condensed consolidated balance sheets primarily related to payroll funding and overhead allocation provided by ETP and other affiliates.

Pursuant to a demand note with Southern Union under a cash management program, the Company loans excess cash, net of repayments, to Southern Union. The Company is credited with interest on the note at a one-month LIBOR rate. Given the uncertainties regarding the timing of the Company’s cash flows, including financings, capital expenditures and operating cash flows, the Company has reported the note receivable as a non-current asset. The Company has access to the funds via advances from Southern Union and expects repayment to ultimately occur to primarily fund capital expenditures or debt retirements.

The following table provides a summary of the related party activity included in our condensed consolidated statements of operations:

Derivative Instruments and Hedging Activities	9 Months Ended
Derivative Instruments and Hedging Activities	Sep. 30, 2013
Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities	DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES: The Company is exposed to certain risks in its ongoing business operations. The primary risk managed by using derivative instruments is interest rate risk. Interest rate swaps and treasury rate locks are the principal derivative instruments used by the Company to manage interest rate risk associated with its long-term borrowings, although other interest rate derivative contracts may also be used from time to time. The Company recognizes all derivative assets and liabilities at fair value on the condensed consolidated balance sheets. Interest Rate Contracts. The Company may enter into interest rate swaps to manage its exposure to changes in interest payments on long-term debt attributable to movements in market interest rates, and may enter into treasury rate locks to manage its exposure to changes in future interest payments attributable to changes in treasury rates prior to the issuance of new long-term debt instruments. Treasury Rate Locks. As of September 30, 2013, the Company had no outstanding treasury rate locks. However, certain of its treasury rate locks that settled in prior periods were associated with interest payments on outstanding long-term debt. During the predecessor periods, these treasury rate locks were accounted for as cash flow hedges, with the effective portion of their settled value recorded in accumulated other comprehensive income and reclassified into interest expense in the same periods during which the related interest payments on long-term debt impact earnings. The Company had no derivative instruments at September 30, 2013 and December 31, 2012. No derivative instrument gains and losses were reported in the Company’s condensed consolidated financial statements for the three and nine months ended September 30, 2013, except for $4 million of unrealized losses reclassified from accumulated other comprehensive income into interest expense during the period from January 1, 2012 to March 25, 2012.

- Definition

The entire disclosure for the entity's entire derivative instruments and hedging activities. Describes an entity's risk management strategies, derivatives in hedging activities and non-hedging derivative instruments, the assets, obligations, liabilities, revenues and expenses arising therefrom, and the amounts of and methodologies and assumptions used in determining the amounts of such items.

Commitments and Contingencies [Abstract]

Commitments and Contingencies Disclosure

COMMITMENTS, CONTINGENCIES AND ENVIRONMENTAL LIABILITIES:

Trunkline Transfer Application

On July 26, 2012, Trunkline filed an application with the FERC for approval to transfer approximately 770 miles of underutilized loop piping facilities by sale to an affiliate; such facilities are contemplated to be converted to crude oil transportation service. This sale is subject to FERC approval. Several parties have intervened, commented, or protested this filing. The Company has responded to all information requests from the Commission and is awaiting a final order in this proceeding.

FERC Audit

The FERC recently completed an audit of PEPL to evaluate its compliance with the Uniform System of Accounts as prescribed by the FERC, annual and quarterly financial reporting to the FERC, reservation charge crediting policy and record retention. The audit related to the period from January 1, 2010 through December 31, 2011. An audit report was received in August 2013 noting no issues that would have a material impact on the Company’s historical financial position or results of operations.

PEPL Holdings Guarantee of Collection

On April 30, 2013, Southern Union completed its contribution to Regency Energy Partners LP (“Regency”) of all the membership interest in Southern Union Gathering Company, LLC, and its subsidiaries, including Southern Union Gas Services (the “SUGS Contribution”). In connection with the SUGS Contribution, Regency issued $600 million of 4.50% Senior Notes due 2023 (the “Regency Debt”), the proceeds of which were used by Regency to fund the cash portion of the consideration, as adjusted, and pay certain other expenses or disbursements directly related to the closing of the SUGS Contribution. In connection with the closing of the SUGS Contribution, Regency entered into an agreement with PEPL Holdings, a wholly-owned subsidiary of Southern Union, pursuant to which PEPL Holdings provided a guarantee of collection (on a nonrecourse basis to Southern Union) to Regency and Regency Energy Finance Corp. with respect to the payment of the principal amount of the Regency Debt through maturity in 2023.

Environmental Matters

The Company’s operations are subject to federal, state and local laws, rules and regulations regarding water quality, hazardous and solid waste management, air quality control and other environmental matters. These laws, rules and regulations require the Company to conduct its operations in a specified manner and to obtain and comply with a wide variety of environmental registrations, licenses, permits, inspections and other approvals. Failure to comply with environmental laws, rules and regulations may expose the Company to significant fines, penalties and/or interruptions in operations. The Company’s environmental policies and procedures are designed to achieve compliance with such applicable laws and regulations. These evolving laws and regulations and claims for damages to property, employees, other persons and the environment resulting from current or past operations may result in significant expenditures and liabilities in the future. The Company engages in a process of updating and revising its procedures for the ongoing evaluation of its operations to identify potential environmental exposures and enhance compliance with regulatory requirements.

Environmental Remediation

The Company is responsible for environmental remediation at certain sites on its natural gas transmission systems for contamination resulting from the past use of lubricants containing PCBs in compressed air systems; the past use of paints containing PCBs; and the prior use of wastewater collection facilities and other on-site disposal areas. The Company has implemented a program to remediate such contamination. The primary remaining remediation activity on the Panhandle systems is associated with past use of paints containing PCBs or PCB impacts to equipment surfaces and to a building at one location. The PCB assessments are ongoing and the related estimated remediation costs are subject to further change. Other remediation typically involves the management of contaminated soils and may involve remediation of groundwater. Activities vary with site conditions and locations, the extent and nature of the contamination, remedial requirements, complexity and sharing of responsibility. The ultimate liability and total costs associated with these sites will depend upon many factors. If remediation activities involve statutory joint and several liability provisions, strict liability, or cost recovery or contribution actions, the Company could potentially be held responsible for contamination caused by other parties. In some instances, the Company may share liability associated with contamination with other potentially responsible parties. The Company may also benefit from contractual indemnities that cover some or all of the cleanup costs. These sites are generally managed in the normal course of business or operations.

The Company’s environmental remediation activities are undertaken in cooperation with and under the oversight of appropriate regulatory agencies, enabling the Company under certain circumstances to take advantage of various voluntary cleanup programs in order to perform the remediation in the most effective and efficient manner.

Environmental Remediation Liabilities

The table below reflects the amount of accrued liabilities recorded on the condensed consolidated balance sheets at the dates indicated to cover environmental remediation actions where management believes a loss is probable and reasonably estimable. The Company does not have any material environmental remediation matters assessed as reasonably possible.

Current	$	—	$	1
Non-current	3		5
Total environmental liabilities	$	3	$	6

Litigation and Other Claims

The Company is involved in legal, tax and regulatory proceedings before various courts, regulatory commissions and governmental agencies regarding matters arising in the ordinary course of business.

Liabilities for Litigation and Other Claims

The Company records accrued liabilities for litigation and other claim costs when management believes a loss is probable and reasonably estimable. When management believes there is at least a reasonable possibility that a material loss or an additional material loss may have been incurred, the Company discloses (i) an estimate of the possible loss or range of loss in excess of the amount accrued; or (ii) a statement that such an estimate cannot be made. As of September 30, 2013 and December 31, 2012, the Company recorded litigation and other claim-related accrued liabilities of $6 million and $6 million, respectively. The Company does not have any material litigation or other claim contingency matters assessed as probable or reasonably possible that would require disclosure in the financial statements.

Other Commitments and Contingencies

Controlled Group Pension Liabilities. Southern Union (including certain of its divisions) sponsors a number of defined benefit pension plans for employees. Under applicable pension and tax laws, upon being acquired by Southern Union, the Company became a member of Southern Union’s “controlled group” with respect to those plans and, along with Southern Union and any other members of that group, is jointly and severally liable for any failure by Southern Union (along with any other persons that may be or become a sponsor of any such plan) to fund any of these pension plans or to pay any unfunded liabilities that these plans may have if they are ever terminated. In addition, if any of the obligations of any of these pension plans is not paid when due, a lien in favor of that plan or the Pension Benefit Guaranty Corporation may be created against the assets of each member of Southern Union’s controlled group, including the Company and each of its subsidiaries. Based on the latest actuarial information available, the aggregate amount of the projected benefit obligations of these pension plans was approximately $243 million and the estimated fair value of all of the assets of these plans was approximately $155 million.

Unclaimed Property Audits. The Company is subject to the laws and regulations of states and other jurisdictions concerning the identification, reporting and escheatment (the transfer of property to the state) of unclaimed or abandoned funds, and is subject to audit and examination for compliance with these requirements. The Company is currently being examined by a third party auditor on behalf of nine states for compliance with unclaimed property laws.

Future Regulatory Compliance Commitments

Air Quality Control. On April 17, 2012 the EPA issued the Oil and Natural Gas Sector New Source Performance Standards and National Emission Standards for Hazardous Air Pollutants (“HAPs”). The standards revise the new source performance standards for volatile organic compounds from leaking components at onshore natural gas processing plants and new source performance standards for sulfur dioxide emissions from natural gas processing plants. The EPA also established standards for certain oil and gas operations not covered by the existing standards. In addition to the operations covered by the existing standards, the newly established standards regulate volatile organic compound emissions from gas wells, centrifugal compressors, reciprocating compressors, pneumatic controllers and storage vessels.

In August 2010, the EPA finalized a rule that requires reductions in a number of pollutants, including formaldehyde and carbon monoxide, for certain engines regardless of size at Area Sources (sources that emit less than 10 tons per year of any one HAP or 25 tons per year of all HAPs) and engines less than 500 horsepower at Major Sources (sources that emit 10 tons per year or more of any one HAP or 25 tons per year of all HAPs). In January 2013, the EPA issued a final reconsideration rule that exempted Area Source engines located in remote areas from the emission limits and monitoring requirements. Compliance was required by October 2013, and the Company believes it is in compliance.

Nitrogen oxides are the primary air pollutant from natural gas-fired engines. Nitrogen oxide emissions may form ozone in the atmosphere. In 2008, the EPA lowered the ozone standard to 75 ppb with compliance anticipated in 2013 to 2015. In January 2010, the EPA proposed lowering the standard to 60 to 70 ppb in lieu of the 75 ppb standard, with compliance required in 2014 or later. In September 2011, the EPA decided to rescind the proposed lower ozone standard and begin the process to implement the 75 ppb ozone standard established in 2008.

In January 2010, the EPA finalized a 100 ppb one-hour nitrogen dioxide standard. The rule requires the installation of new nitrogen dioxide monitors in urban communities and roadways by 2013. This new monitoring may result in additional nitrogen dioxide non-attainment areas. In addition, ambient air quality modeling may be required to demonstrate compliance with the new standard.

The Company has reviewed the potential impacts of the August 2010 Area Source National Emissions Standards for Hazardous Air Pollutants rule, implementation of the 2008 ozone standard and the new nitrogen dioxide standard on its operations and the potential costs associated with the installation of emission control systems on its existing engines. The ultimate costs associated with these activities cannot be estimated with any certainty at this time, but the Company believes, based on the current understanding of the current and proposed rules, such costs will not have a material adverse effect on its consolidated financial position, results of operations or cash flows.

- Definition

Assets, usually stocks, bonds, and other investments, that have been segregated and restricted (usually in a trust) to provide benefits, at their fair value as of the measurement date. Plan assets include amounts contributed by the employer (and by employees for a contributory plan) and amounts earned from investing the contributions, less benefits paid. If a plan has liabilities other than for benefits, those non-benefit obligations may be considered as reductions of plan assets.
