Basis of Presentation
Our results of operations for the three and six months ended June 30, 2007 are not necessarily indicative of results expected for the full year.
Except per unit amounts, or as noted within the context of each footnote disclosure, the dollar amounts presented in the tabular data within these footnote disclosures are stated in thousands of dollars.
Essentially all of our assets, liabilities, revenues and expenses are recorded at EPOs level in our consolidated financial statements. We act as guarantor of certain of EPOs debt obligations. See Note 17 for condensed consolidated financial information of EPO.
In our opinion, the accompanying Unaudited Condensed Consolidated Financial Statements include all adjustments consisting of normal recurring accruals necessary for fair presentation. Although we believe the disclosures in these financial statements are adequate to make the information presented not misleading, certain information and footnote disclosures normally included in annual financial statements prepared in accordance with generally accepted accounting principles in the United States of America (GAAP) have been condensed or omitted pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (SEC). These Unaudited Condensed Consolidated Financial Statements should be read in conjunction with our annual report on Form 10-K for the year ended December 31, 2006 (Commission File No. 1-14323).
Note 2. General Accounting Policies and Related Matters
Accounting for Employee Benefit Plans
Dixie Pipeline Company (Dixie), a consolidated subsidiary, employs the personnel that operate its pipeline system and certain of these employees are eligible to participate in a defined contribution plan and pension and postretirement benefit plans. Due to the immaterial nature of Dixies employee benefit plans to our consolidated financial position, results of operations and cash flows, our discussion is limited to the following:
Defined Contribution Plan. Dixie contributed $0.1 million to its company-sponsored defined contribution plan during each of the three month periods ended June 30, 2007 and 2006. During each of the six month periods ended June 30, 2007 and 2006, Dixie contributed $0.2 million to its company-sponsored defined contribution plan.
Pension and Postretirement Benefit Plans. Dixies net pension benefit costs were $0.1 million and $0.2 million for the three months ended June 30, 2007 and 2006, respectively. For each of the six month periods ended June 30, 2007 and 2006, Dixies net pension benefit costs were $0.3 million. Dixies net postretirement benefit costs were $0.1 million for each of the three month periods ended June 30, 2007 and 2006. For the six months ended June 30, 2007 and 2006, Dixies net postretirement benefit costs were $0.2 million and $0.1 million, respectively. During the remainder of 2007, Dixie expects to contribute approximately $1.2 million to its postretirement benefit plan and approximately $0.2 million to its pension plan.
We evaluate our financial interests in business enterprises to determine if they represent variable interest entities where we are the primary beneficiary. If such criteria are met, we consolidate the financial statements of such businesses with those of our own. Our consolidated financial statements include our accounts and those of our majority-owned subsidiaries in which we have a controlling interest, after the elimination of intercompany accounts and transactions. We also consolidate other entities and ventures in which we possess a controlling financial interest as well as partnership interests where we are the sole general partner of the partnership.
If the investee is organized as a limited partnership or limited liability company and maintains separate ownership accounts, we account for our investment using the equity method if our ownership interest is between 3% and 50% and we exercise significant influence over the investees operating and financial policies. For all other types of investments, we apply the equity method of accounting if our ownership interest is between 20% and 50% and we exercise significant influence over the investees operating and financial policies. Our proportionate share of profits and losses from transactions with equity method unconsolidated affiliates are eliminated in consolidation to the extent such amounts remain on our balance sheet (or those of our equity method investees) in inventory or similar accounts.
If our ownership interest in an investee does not provide us with either control or significant influence over the investee, we account for the investment using the cost method.
Cumulative Effect of Change in Accounting Principle
In January 2006, we adopted the provisions of Statement of Financial Accounting Standards (SFAS) 123(R), Share-Based Payment. Upon adoption of this accounting standard, we recognized, as a benefit, a cumulative effect of change in accounting principle of $1.5 million.
Environmental costs for remediation are accrued based on estimates of known remediation requirements. Such accruals are based on managements best estimate of the ultimate cost to remediate a site and are adjusted as further information and circumstances develop. Those estimates may change substantially depending on information about the nature and extent of contamination, appropriate remediation technologies, and regulatory approvals. Ongoing environmental compliance costs are charged to expense as incurred. In accruing for environmental remediation liabilities, costs of future expenditures for environmental remediation are not discounted to their present value, unless the amount and timing of the expenditures are fixed or reliably determinable. Expenditures to mitigate or prevent future environmental contamination are capitalized.
At June 30, 2007 and December 31, 2006, our accrued liabilities for environmental remediation projects totaled $28.6 million and $24.2 million, respectively. These amounts were derived from a range of reasonable estimates based upon studies and site surveys. Unanticipated changes in circumstances and/or legal requirements could result in expenses being incurred in future periods in addition to an increase in actual cash required to remediate contamination for which we are responsible.
In February 2007, we reserved $6.5 million in cash received from a third party to fund anticipated future environmental remediation costs associated with certain assets that we had acquired from the third party. Previously, the third party had been obligated to indemnify us for such costs. As a result of the settlement, this indemnification was terminated.
Preparing our Unaudited Condensed Consolidated Financial Statements in conformity with GAAP requires management to make estimates and assumptions that affect reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Our actual results could differ from these estimates. On an ongoing basis, management reviews its estimates based on currently available information. Changes in facts and circumstances may result in revised estimates.
We are organized as a pass-through entity for income tax purposes. As a result, our partners are responsible for federal income taxes on their share of our taxable income. For the three and six months ended June 30, 2007 and 2006, our provision for income taxes is applicable to state tax obligations under
the Texas Margin Tax and certain federal and state tax obligations of Seminole Pipeline Company (Seminole) and Dixie.
In accordance with Financial Accounting Standards Board Interpretation (FIN) 48, Accounting for Uncertainty in Income Taxes, we must recognize the tax effects of any uncertain tax positions we may adopt, if the position taken by us is more likely than not sustainable. If a tax position meets such criteria, the tax effect to be recognized by us would be the largest amount of benefit with more than a 50% chance of being realized upon settlement. This guidance was effective January 1, 2007, and our adoption of this guidance had no material impact on our financial position, results of operations or cash flows.
As presented in our Unaudited Condensed Consolidated Balance Sheets, minority interest represents third-party ownership interests in the net assets of our consolidated subsidiaries. For financial reporting purposes, the assets and liabilities of our majority owned subsidiaries are consolidated with those of our own, with any third-party ownership interests in such amounts presented as minority interest. Effective February 1, 2007, the public owners of Duncan Energy Partners common units are presented as a minority interest in our consolidated financial statements.
Minority interest, as reflected on our June 30, 2007 balance sheet, consists of $293.5 million attributable to third party owners of Duncan Energy Partners and the remainder to our other consolidated affiliates.
Minority interest expense for the three and six months ended June 30, 2007 includes $3.3 million and $6.1 million, respectively, attributable to third party owners of Duncan Energy Partners. The remaining minority interest expense amounts for these periods in 2007 and likewise those for 2006 are attributable to our other consolidated affiliates.
Contributions from minority interests for the six months ended June 30, 2007 includes $291.0 million received from third parties in connection with the initial public offering of Duncan Energy Partners in February 2007.
Recent Accounting Developments
SFAS 157, Fair Value Measurements, defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles, and expands disclosures about fair value measurements. SFAS 157 is effective for fiscal years beginning after November 15, 2007 and we will be required to adopt SFAS 157 on January 1, 2008. We do not believe SFAS 157 will have a material impact on our financial position, results of operations, and cash flows since we already apply its basic concepts in measuring fair values used to record various transactions such as business combinations and asset acquisitions.
SFAS 159, Fair Value Option for Financial Assets and Financial Liabilities Including an amendment of FASB Statement No. 115, permits entities to choose to measure many financial assets and financial liabilities at fair value. Unrealized gains and losses on items for which the fair value option has been elected would be reported in net income. SFAS 159 also establishes presentation and disclosure requirements designed to draw comparisons between the different measurement attributes the company elects for similar types of assets and liabilities. SFAS 159 is effective for fiscal years beginning after November 15, 2007. We do not believe SFAS 159 will have a material impact on our financial position, results of operations, and cash flows.
Note 3. Accounting for Unit-Based Awards
We account for unit-based awards in accordance with SFAS 123(R). SFAS 123(R) requires us to recognize compensation expense related to equity awards based on the fair value of the award at grant date. The fair value of restricted unit awards is based on the market price of the underlying common units on the date of grant. The fair value of other unit-based awards is estimated using the Black-Scholes option pricing model. Under SFAS 123(R), the fair value of an equity-classified award is amortized to earnings on a straight-line basis over the requisite service or vesting period. Compensation expense for liability-classified awards is recognized over the requisite service or vesting period of an award based on the fair value of the award remeasured at each reporting period.
Unit Options and Restricted Units
Under EPCOs 1998 Long-Term Incentive Plan (the 1998 Plan), non-qualified incentive options to purchase a fixed number of our common units may be granted to EPCOs key employees who perform management, administrative or operational functions for us.
The information in the following table presents unit option activity under the 1998 Plan for the periods indicated:
The total intrinsic value of unit options exercised during the three and six months ended June 30, 2007 was $1.2 million and $2.8 million, respectively. We recognized $3.9 million and $0.2 million of compensation expense associated with unit options during the three month periods ended June 30, 2007 and 2006, respectively. We recognized $4.1 million and $0.3 million of compensation expense associated with unit options during the six months ended June 30, 2007 and 2006, respectively. Compensation expense for the three and six months ended June 30 ,2007 includes $3.7 million associated with the resignation of our former chief executive officer.
As of June 30, 2007, there was an estimated $3.2 million of total unrecognized compensation cost related to non-vested unit options granted under the 1998 Plan. We expect to recognize our share of this cost over a weighted-average period of 3.25 years in accordance with the EPCO administrative services agreement.
During the six months ended June 30, 2007 and 2006, we received cash of $7.3 million and $1.6 million, respectively, from the exercise of unit options, and our option-related reimbursements to EPCO were $2.8 million and $0.7 million, respectively.
Under the 1998 Plan, we may also issue restricted common units to key employees of EPCO and directors of our general partner. The following table summarizes information regarding our restricted common units for the periods indicated:
During the three months ended June 30, 2007 and 2006, we recognized $2.3 million and $1.8 million, respectively, of compensation expense in connection with restricted common units. We recognized $3.7 million and $2.7 million of compensation expense in connection with restricted common units during the six months ended June 30, 2007 and 2006, respectively. No restricted units vested during the three and six months ended June 30, 2007. Compensation expense for the three and six months ended June 30 ,2007 includes $0.9 million associated with the resignation of our former chief executive officer.
As of June 30, 2007, there was $27.8 million of total unrecognized compensation cost related to restricted common units. We will recognize our share of such costs in accordance with the EPCO administrative services agreement. At June 30, 2007, these costs are expected to be recognized over a weighted-average period of 2.8 years.
The 1998 Plan provides for the issuance of up to 7,000,000 common units. As of June 30, 2007, 1,689,500 common units had been issued in connection with the exercise of unit options. After giving effect to outstanding unit options at June 30, 2007 and the issuance and forfeiture of restricted common units through June 30, 2007, a total of 3,606,303 additional common units could be issued under the 1998 Plan.
For the three months ended June 30, 2007 and 2006, we recorded $0.7 million and $0.6 million, respectively, of compensation expense associated with EPE Unit I, EPE Unit II and EPE Unit III (the Employee Partnerships). We recorded $1.2 million and $1.1 million of compensation expense associated with the Employee Partnerships during the six months ended June 30, 2007 and 2006, respectively. As of June 30, 2007, there was $8.2 million of total unrecognized compensation cost related to EPE Unit I and EPE Unit II, of which we will recognize our share in accordance with the EPCO administrative services agreement.
EPE Unit III. EPE Unit III was formed on May 7, 2007 and owns 4,421,326 units of Enterprise GP Holdings contributed to it by a private company affiliate of EPCO, which, in turn, was made the Class A limited partner of EPE Unit III. On the date of contribution, the fair market value of the units contributed by the Class A limited partner was $170.0 million (the Class A limited partner capital base). Certain EPCO employees were issued Class B limited partner interests and admitted as Class B limited partners of EPE Unit III without any capital contribution. The profits interest awards (i.e., Class B limited partner interests) in EPE Unit III entitle the holder to participate in the appreciation in value of units of Enterprise GP Holdings owned by EPE Unit III.
Unless otherwise agreed to by EPCO, the Class A limited partner and a majority in interest of the Class B limited partners of EPE Unit III, EPE Unit III will be liquidated upon the earlier of: (i) May 7, 2012 or (ii) a change in control of Enterprise GP Holdings or its general partner. EPE Unit III has the following material terms regarding its quarterly cash distribution to partners:
The Class B limited partner interests in EPE Unit III that are owned by EPCO employees are subject to forfeiture if the participating employees employment with EPCO and its affiliates is terminated prior to May 7, 2012, with customary exceptions for death, disability and certain retirements. The risk of forfeiture associated with the Class B limited partner interests in EPE Unit III will also lapse upon certain change of control events.
As of June 30, 2007, there was $22.4 million of total unrecognized compensation cost related to these awards, of which we will recognize our share in accordance with the EPCO administrative services agreement.
Note 4. Financial Instruments
We are exposed to financial market risks, including changes in commodity prices and interest rates. In addition, we are exposed to fluctuations in exchange rates between the U.S. dollar and Canadian dollar. We may use financial instruments (i.e., futures, forwards, swaps, options and other financial instruments with similar characteristics) to mitigate the risks of certain identifiable and anticipated transactions. In general, the type of risks we attempt to hedge are those related to (i) variability of future earnings, (ii) fair values of certain debt instruments and (iii) cash flows resulting from changes in applicable interest rates, commodity prices or exchange rates. As a matter of policy, we do not use financial instruments for speculative (or trading) purposes.
Interest Rate Risk Hedging Program
Our interest rate exposure results from variable and fixed interest rate borrowings under various debt agreements. We manage a portion of our interest rate exposure by utilizing interest rate swaps and similar arrangements, which allow us to convert a portion of fixed rate debt into variable rate debt or a portion of variable rate debt into fixed rate debt.
Fair Value Hedges Interest Rate Swaps. As summarized in the following table, we had eleven interest rate swap agreements outstanding at June 30, 2007 that were accounted for as fair value hedges.
The total fair value of these eleven interest rate swaps at June 30, 2007 and December 31, 2006, was a liability of $49.7 million and $29.1 million, respectively, with an offsetting decrease in the fair value of the underlying debt. Interest expense for the three months ended June 30, 2007 and 2006 includes a $2.3 million and $1.1 million loss from these swap agreements, respectively. For the six months ended June 30, 2007 and 2006, interest expense reflects a loss of $4.6 million and $0.9 million from these swap agreements, respectively.
Cash Flow Hedges Treasury Locks. During the fourth quarter of 2006, EPO entered into treasury lock transactions having a notional value of $562.5 million. EPO entered into these transactions to hedge the underlying U.S. treasury rates related to its anticipated issuances of debt during the second and fourth quarters of 2007. On February 27, 2007, EPO entered into additional treasury lock transactions having a notional value of $437.5 million. EPO entered into these transactions to hedge the underlying U.S. treasury rates related to its anticipated issuances of debt during 2007. Each of the treasury lock transactions was designated as a cash flow hedge under SFAS 133, Accounting for Derivative Instruments and Hedging Activities, as amended and interpreted.
During the second quarter of 2007, treasury locks having a notional amount of $875.0 million were terminated. Treasury locks having a notional amount of $500.0 million were terminated concurrent with the issuance of EPOs Junior Notes B (see Note 9). An additional $375.0 million notional amount of treasury locks related to the anticipated issuance of debt in the fourth quarter of 2007 were also terminated. The termination of the treasury locks resulted in gains of $42.3 million of which $10.6 million is related to EPOs Junior Notes B and the remaining $31.7 million is related to a future debt issuance. The $10.6 million gain is being amortized into income using the effective interest method as reductions to future interest expense over the fixed rate term of the Junior Notes B, which is ten years. The remaining $31.7 million gain will be amortized into income over the life of the future debt issuance using the effective interest rate method.
At June 30, 2007, there was one treasury lock outstanding which has a notional amount of $125.0 million and a fair value of $9.3 million.
Commodity Risk Hedging Program
The prices of natural gas, NGLs and certain petrochemical products are subject to fluctuations in response to changes in supply, market uncertainty and a variety of additional factors that are beyond our control. In order to manage the price risks associated with such products, we may enter into commodity financial instruments.
The primary purpose of our commodity risk management activities is to hedge our exposure to price risks associated with (i) natural gas purchases, (ii) the value of NGL production and inventories, (iii) related firm commitments, (iv) fluctuations in transportation revenues where the underlying fees are based on natural gas index prices and (v) certain anticipated transactions involving either natural gas, NGLs or certain petrochemical products. From time to time, we inject natural gas into storage and utilize hedging instruments to lock in the value of our inventory positions. The commodity financial instruments we utilize may be settled in cash or with another financial instrument.
At June 30, 2007 and December 31, 2006, we had a limited number of commodity financial instruments in our portfolio, which primarily consisted of cash flow hedges. The fair value of our commodity financial instrument portfolio at June 30, 2007 and December 31, 2006 was a liability of $1.0 million and $3.2 million, respectively. During the three and six months ended June 30, 2007, we recorded income of $1.1 million and expense of $1.3 million, respectively, related to our commodity financial instruments. During the three and six months ended June 30, 2006 we recorded $5.9 million and $5.5 million, respectively, of expense related to our commodity financial instruments.
Foreign Currency Hedging Program
We own an NGL marketing business located in Canada and have entered into construction agreements where payments are indexed to the Canadian dollar. As a result, we could be adversely affected by fluctuations in the foreign currency exchange rate between the U.S. dollar and the Canadian dollar. We attempt to hedge this risk using foreign exchange purchase contracts to fix the exchange rate. Due to the limited duration of these contracts, we utilize mark-to-market accounting for these transactions, the effect of which has had a minimal impact on our earnings. We had $3.1 million of such contracts outstanding at June 30, 2007 that settled in July 2007.
Note 5. Inventories
Our regular trade (or working) inventory is comprised of inventories of natural gas, NGLs, and certain petrochemical products that are available-for-sale or used by us in the provision of services. Our forward sales inventory consists of segregated NGL and natural gas volumes dedicated to the fulfillment of forward-sales contracts. Our inventory values reflect payments for product purchases, freight charges associated with such purchase volumes, terminal and storage fees, vessel inspection costs, demurrage charges and other related costs. We value our inventories at the lower of average cost or market.
Operating costs and expenses, as presented on our Unaudited Condensed Statements of Consolidated Operations, include cost of sales amounts related to the sale of inventories. Our cost of sales was $3.6 billion and $3.0 billion for the three months ended June 30, 2007 and 2006, respectively. For the six months ended June 30, 2007 and 2006, our cost of sales was $6.4 billion and $5.7 billion, respectively.
Due to fluctuating commodity prices in the NGL, natural gas and petrochemical industry, we recognize lower of cost or market (LCM) adjustments when the carrying value of our inventories exceed their net realizable value. These non-cash charges are a component of cost of sales in the period they are recognized. For the three months ended June 30, 2007 and 2006, we recognized LCM adjustments of approximately $2.1 million and $0.3 million, respectively. We recognized LCM adjustments of $13.1 million and $12.0 million for the six months ended June 30, 2007 and 2006, respectively.
Note 6. Property, Plant and Equipment
Our property, plant and equipment values and accumulated depreciation balances were as follows at the dates indicated:
Depreciation expense for the three months ended June 30, 2007 and 2006 was $99.1 million and $86.9 million, respectively. For the six months ended June 30, 2007 and 2006, depreciation expense was $194.1 million and $170.4 million, respectively. We capitalized $20.4 million and $12.4 million of interest in connection with capital projects during the three months ended June 30, 2007 and 2006, respectively. During the six months ended June 30, 2007 and 2006, we capitalized $41.1 million and $21.6 million, respectively, in connection with capital projects.
Note 7. Investments In and Advances to Unconsolidated Affiliates
We own interests in a number of related businesses that are accounted for using the equity method of accounting. Our investments in and advances to unconsolidated affiliates are grouped according to the business segment to which they relate. See Note 11 for a general discussion of our business segments.
The following table presents our investments in and advances to unconsolidated affiliates at the dates indicated:
On occasion, the price we pay to acquire an ownership interest in a company exceeds the underlying book value of the capital accounts we acquire. Such excess cost amounts are included within the carrying values of our investments in and advances to unconsolidated affiliates. At June 30, 2007 and December 31, 2006, our investments in Promix, La Porte, Neptune, Poseidon, Cameron Highway, Nemo and Jonah included excess cost amounts totaling $42.9 million and $38.7 million, respectively. These amounts are attributable to the excess of the fair value of each entitys tangible assets over their respective book carrying values at the time we acquired an interest in each entity. We amortize such excess cost amounts as a reduction in equity earnings. Amortization of such excess cost amounts was $0.5 million and $0.6 million during the three months ended June 30, 2007 and 2006, respectively. For the six months ended June 30, 2007 and 2006, amortization of such amounts was $1.0 million and $1.1 million, respectively.
The following table presents our equity in income (loss) of unconsolidated affiliates by business segment for the periods indicated:
Summarized Financial Information of Unconsolidated Affiliates
The following tables present unaudited income statement data for our current unconsolidated affiliates, aggregated by business segment, for the periods indicated (on a 100% basis).
We own a 50.0% interest in Cameron Highway, which owns a crude oil pipeline that gathers production from deepwater areas of the Gulf of Mexico, primarily the South Green Canyon area, for delivery to refineries and terminals in southeast Texas. In May 2007, we made an approximate $191.0 million cash contribution to Cameron Highway. This capital contribution, along with an equal amount contributed by our joint venture partner in Cameron Highway, was used by Cameron Highway to repay $365.0 million outstanding under its Senior Notes A and $14.1 million of related make-whole premiums and accrued interest. In June 2007, we and our joint venture partner in Cameron Highway, made an additional capital contribution of approximately $25.5 million each. These capital contributions were used by Cameron Highway to repay its Series B notes on June 7, 2007. The amount of the repayment was $50.9 million, which included $0.9 million of related make-whole premiums and accrued interest. As of June 30, 2007, Cameron Highway no longer has any outstanding debt.
Nemo was formed in 1999 to construct, own and operate the Nemo Gathering System, a 24-mile natural gas gathering system in the Gulf of Mexico offshore Louisiana. The Nemo Gathering System, which began operations in 2001, gathers natural gas from certain developments in the Green Canyon area of the Gulf of Mexico to a pipeline interconnect with the Manta Ray Gathering System. Due to a recent decrease in throughput volumes on the Nemo Gathering System, we evaluated our 33.9% investment in Nemo for impairment during the second quarter of 2007. The decrease in throughput volumes is primarily due to underperformance of certain fields and natural depletion.
At December 31, 2006, the carrying value of our investment in Nemo was $11.2 million, which included $0.6 million of excess cost related to its original acquisition in 2001. Our review of Nemos estimated future cash flows during the second quarter of 2007 indicated that the carrying value of our investment exceeded its fair value, which resulted in a non-cash charge of $7.0 million. This loss is recorded as a component of Equity in income of unconsolidated affiliates in our Unaudited Condensed Statements of Consolidated Operations for the three and six months ended June 30, 2007. Equity earnings from our investment in Nemo are classified under our Offshore Pipelines & Services business segment.
After recording this impairment charge, the carrying value of our investment in Nemo at June 30, 2007 was $2.6 million, which reflects $0.5 million in losses and $2.0 million of distributions we recorded during the first six months of 2007.
Our investment in Nemo was written down to fair value, which management prepared using recognized business valuation techniques. The fair value analysis is based upon managements expectation of future cash flows. Such expectation of future cash flows incorporates industry information and assumptions made by management. For example, the review of Nemo included management estimates regarding the remaining natural gas reserves of producers served by the Nemo Gathering System. If the assumptions underlying our fair value analysis change and expected cash flows are reduced, additional impairment charges may result.

Note 9. Debt Obligations
Our consolidated debt obligations consisted of the following at the dates indicated:
Parent-Subsidiary guarantor relationships
We act as guarantor of the debt obligations of EPO with the exception of the Dixie revolving credit facility and the senior subordinated notes we assumed in connection with the GulfTerra Merger. If EPO were to default on any debt we guarantee, we would be responsible for full repayment of that obligation. We do not act as guarantor of the debt obligations of Duncan Energy Partners.
EPOs debt obligations
Apart from that discussed below, there have been no significant changes in the terms of EPOs debt obligations since those reported in our annual report on Form 10-K for the year ended December 31, 2006.
Junior Notes B. EPO sold $700 million in principal amount of fixed/floating, unsecured, long-term subordinated notes due January 2068 (Junior Notes B) during the second quarter of 2007. EPO used the proceeds from this subordinated debt to temporarily reduce borrowings outstanding under its Multi-Year Revolving Credit Facility and for general partnership purposes. EPOs payment obligations under Junior Notes B are subordinated to all of its current and future senior indebtedness (as defined in the
Indenture Agreement). We have guaranteed repayment of amounts due under Junior Notes B through an unsecured and subordinated guarantee.
The indenture agreement governing Junior Notes B allows EPO to defer interest payments on one or more occasions for up to ten consecutive years subject to certain conditions. During any period in which interest payments are deferred and subject to certain exceptions, neither we nor EPO can declare or make any distributions to any of our respective equity securities or make any payments on indebtedness or other obligations that rank pari passu with or are subordinate to Junior Notes B. Junior Notes B rank pari passu with the Junior Subordinated Notes A, due August 2066 (Junior Notes A), which were issued during the third quarter of 2006.
The Junior Notes B will bear interest at a fixed annual rate of 7.034% through January 15, 2018, payable semi-annually in arrears in January and July of each year, commencing in January 2008. After January 2018, the Junior Notes B will bear variable rate interest at the greater of (1) the sum of the 3-month London Interbank Offered Rate (LIBOR) for the related interest period plus a spread of 268 basis points or (2) 7.034% per annum, payable quarterly in arrears in January, April, July and October of each year commencing in April 2018. Interest payments may be deferred on a cumulative basis for up to ten consecutive years, subject to the certain provisions. The Junior Notes B mature in January 2068 and are not redeemable by EPO prior to January 2018 without payment of a make-whole premium.
In connection with the issuance of Junior Notes B, we and EPO entered into a Replacement Capital Covenant in favor of the covered debt holders (as named therein) pursuant to which we and EPO agreed for the benefit of such debt holders that we nor EPO would not redeem or repurchase such junior notes on or before January 15, 2038, unless such redemption or repurchase is made from the proceeds of issuance of certain securities.
Duncan Energy Partners debt obligation
We consolidate the debt of Duncan Energy Partners with that of our own; however, we do not have the obligation to make interest payments or debt payments with respect to the debt of Duncan Energy Partners.
Duncan Energy Partners entered into a $300.0 million revolving credit facility, all of which may be used for letters of credit, with a $30.0 million sublimit for Swingline loans. Letters of credit outstanding under this facility reduce the amount available for borrowings. At the closing of its initial public offering, Duncan Energy Partners made its initial borrowing of $200.0 million under the facility to fund the $198.9 million cash distribution to EPO and the remainder to pay debt issuance costs. At June 30, 2007, the balance outstanding under this facility was $190.0 million.
This credit facility matures in February 2011 and will be used by Duncan Energy Partners in the future to fund working capital and other capital requirements and for general partnership purposes. Duncan Energy Partners may make up to two requests for one-year extensions of the maturity date (subject to certain restrictions). The revolving credit facility is available to pay distributions upon the initial contribution of assets to Duncan Energy Partners, fund working capital, make acquisitions and provide payment for general purposes. Duncan Energy Partners can increase the revolving credit facility, without consent of the lenders, by an amount not to exceed $150.0 million by adding to the facility one or more new lenders and/or increasing the commitments of existing lenders. No existing lender is required to increase its commitment, unless it agrees to do so in its sole discretion.
This revolving credit facility offers the following unsecured loans, each having different interest requirements: (i) LIBOR loans bear interest at a rate per annum equal to LIBOR plus the applicable LIBOR margin (as defined in the credit agreement), (ii) Base Rate loans bear interest at a rate per annum equal to the higher of (a) the rate of interest publicly announced by the administrative agent, Wachovia Bank, National Association, as its Base Rate and (b) 0.5% per annum above the Federal Funds Rate in effect on such date and (iii) Swingline loans bear interest at a rate per annum equal to LIBOR plus an applicable LIBOR margin.
The revolving credit facility requires Duncan Energy Partners to maintain a leverage ratio for the prior four fiscal quarters of not more than 4.75 to 1.00 at the last day of each fiscal quarter commencing June 30, 2007; provided that, upon the closing of a permitted acquisition, such ratio shall not exceed (a) 5.25 to 1.00 at the last day of the fiscal quarter in which such specified acquisition occurred and at the last day of each of the two fiscal quarters following the fiscal quarter in which such specified acquisition occurred, and (b) 4.75 to 1.00 at the last day of each fiscal quarter thereafter. In addition, prior to obtaining an investment-grade rating by Standard & Poors Ratings Services, Moodys Investors Service or Fitch Ratings, Duncan Energy Partners interest coverage ratio, for the prior four fiscal quarters shall not be less than 2.75 to 1.00 at the last day of each fiscal quarter commencing June 30, 2007.
The Duncan Energy Partners credit facility contains other customary covenants. Also, if an event of default exists under the credit agreement, the lenders will be able to accelerate the maturity date of amounts borrowed under the credit agreement and exercise other rights and remedies.
Canadian Debt Obligations
In May 2007, Canadian Enterprise Gas Products, Ltd. (Canadian Enterprise), a wholly-owned subsidiary of EPO, entered into a $30.0 million Canadian revolving credit facility with The Bank of Nova Scotia. The credit facility, which includes the issuance of letters of credit, matures in October 2011. Letters of credit outstanding under this facility reduce the amount available for borrowings.
Borrowings may be made in Canadian or U.S. dollars. Canadian denominated borrowings may be comprised of Canadian Prime Rate (CPR) loans or Bankers Acceptances and U.S denominated borrowings may be comprised of Alternative Base Rate (ABR) or Eurodollar loans, each having different interest rate requirements. CPR loans bear interest at a rate determined by reference to the Canadian Prime Rate. ABR loans bear interest at a rate determined by reference to an alternative base rate as defined in the credit agreement. Eurodollar loans bear interest at a rate determined by the LIBOR plus an applicable rate as defined in the credit agreement. Bankers Acceptances carry interest at the rate for Canadian bankers acceptances plus an applicable rate as defined in the credit agreement.
The credit facility contains customary covenants and events of default. The restrictive covenants limit Canadian Enterprise from materially changing the nature of its business or operations, dissolving, or completing mergers. A continuing event of default would accelerate the maturity of amounts borrowed under the credit facility. The obligations under the credit facility are guaranteed by EPO.
We are in compliance with the covenants of our consolidated debt agreements at June 30, 2007 and December 31, 2006.
Information regarding variable interest rates paid
The following table presents the range of interest rates paid and weighted-average interest rate paid on our consolidated variable-rate debt obligations during the six months ended June 30, 2007.
Consolidated debt maturity table
The following table presents the scheduled maturities of principal amounts of our debt obligations for the next five years and in total thereafter.
In accordance with SFAS 6, long-term and current maturities of debt reflect the classification of such obligations at June 30, 2007 and December 31, 2006. With respect to the $500.0 million in principal due under Senior Notes E in October 2007, EPO has the ability to use cash and available credit capacity under its Multi-Year Revolving Credit Facility to fund the repayment of this debt. The preceding table and our Unaudited Condensed Consolidated Balance Sheets at June 30, 2007 and December 31, 2006 reflect this ability to refinance.
Debt Obligations of Unconsolidated Affiliates
We have two unconsolidated affiliates with long-term debt obligations. The following table shows (i) our ownership interest in each entity at June 30, 2007, (ii) total debt of each unconsolidated affiliate at June 30, 2007 (on a 100% basis to the affiliate) and (iii) the corresponding scheduled maturities of such debt.
Previously, Cameron Highways debt consisted of $365.0 million of Series A notes and $50.0 million of Series B notes. Cameron Highway repaid its Series A notes on May 23, 2007 using proceeds from capital contributions from its partners. The total amount of the repayment was $379.1 million, which included an $11.0 million make-whole premium and $3.1 million of accrued interest. Our share of the capital contribution was funded by borrowings under EPOs Multi-Year Revolving Credit Facility. With another capital contribution from its partners, Cameron Highway also repaid its Series B notes on June 7, 2007. The amount of the repayment was $50.9 million, which included a $0.3 million make-whole premium and $0.6 million of accrued interest. As of June 30, 2007, Cameron Highway no longer has any outstanding debt.
The credit agreements of our unconsolidated affiliates contain various affirmative and negative covenants, including financial covenants. These businesses were in compliance with such covenants at June 30, 2007. The credit agreements of our unconsolidated affiliates restrict their ability to pay cash dividends if a default or an event of default (as defined in each credit agreement) has occurred and is continuing at the time such dividend is scheduled to be paid.
Apart from the repayment of Cameron Highways Series A and Series B notes, there have been no significant changes in the terms of the debt obligations of our unconsolidated affiliates since those reported in our annual report on Form 10-K for the year ended December 31, 2006.
Note 10. Partners Equity and Distributions
Our common units represent limited partner interests, which give the holders thereof the right to participate in distributions and to exercise the other rights or privileges available to them under our Fifth Amended and Restated Agreement of Limited Partnership (together with all amendments thereto, the Partnership Agreement). We are managed by our general partner, Enterprise Products GP.
In accordance with the Partnership Agreement, capital accounts are maintained for our general partner and limited partners. The capital account provisions of our Partnership Agreement incorporate principles established for U.S. Federal income tax purposes and are not comparable to the equity accounts reflected under GAAP in our consolidated financial statements.
Our Partnership Agreement sets forth the calculation to be used in determining the amount and priority of cash distributions that our limited partners and general partner will receive. The Partnership Agreement also contains provisions for the allocation of net earnings and losses to our limited partners and general partner. For purposes of maintaining partner capital accounts, the Partnership Agreement specifies that items of income and loss shall be allocated among the partners in accordance with their respective percentage interests. Normal income and loss allocations according to percentage interests are done only after giving effect to priority earnings allocations in an amount equal to incentive cash distributions allocated to our general partner.
Equity Offerings and Registration Statements
In general, the Partnership Agreement authorizes us to issue an unlimited number of additional limited partner interests and other equity securities for such consideration and on such terms and conditions as may be established by Enterprise Products GP in its sole discretion (subject, under certain circumstances, to the approval of our unitholders).
We have a universal shelf registration statement on file with the SEC registering the issuance of up to $4 billion of equity and debt securities. After taking into account past issuance of securities under this registration statement, we have the ability to issue approximately $1.4 billion of additional securities under this registration statement as of June 30, 2007.
In April 2007, we filed a registration statement with the SEC authorizing the issuance of up to 25,000,000 common units in connection with our distribution reinvestment plan (DRIP). The DRIP provides unitholders of record and beneficial owners of our common units a voluntary means by which they can increase the number of common units they own by reinvesting the quarterly cash distributions they would otherwise receive into the purchase of additional common units. A total of 932,800 of our common units were issued in February 2007 and May 2007 in connection with the DRIP and the employee unit purchase plan (EUPP). The issuance of these units generated $28.6 million in net proceeds.
In May 2007, EPO sold $700 million in principal amount of Junior Notes B under our universal shelf registration statement. For additional information regarding this debt offering, see Note 9.
The following table reflects the number of common units issued and the net proceeds received from underwritten and other common unit offerings completed during the six months ended June 30, 2007:
Summary of Changes in Outstanding Units
The following table summarizes changes in our outstanding units since December 31, 2006:
Summary of Changes in Limited Partners Equity
The following table details the changes in limited partners equity since December 31, 2006:
Distributions to Partners
The percentage interest of Enterprise Products GP in our quarterly cash distributions is increased after certain specified target levels of quarterly distribution rates are met. At current distribution rates, we are in the highest tier of such incentive targets. Enterprise Products GPs quarterly incentive distribution thresholds are as follows:
We paid incentive distributions of $26.3 million and $21.0 million to Enterprise Products GP during the three months ended June 30, 2007 and 2006, respectively. During the six months ended June 30, 2007 and 2006, we paid incentive distributions of $51.6 million and $40.1 million, respectively, to Enterprise Products GP.
Our quarterly cash distributions for 2007 are presented in the following table:
Note 11. Business Segments
We have four reportable business segments: NGL Pipelines & Services; Onshore Natural Gas Pipelines & Services; Offshore Pipelines & Services; and Petrochemical Services. Our business segments are generally organized and managed according to the type of services rendered (or technologies employed) and products produced and/or sold.
We evaluate segment performance based on the non-GAAP financial measure of gross operating margin. Gross operating margin (either in total or by individual segment) is an important performance measure of the core profitability of our operations. This measure forms the basis of our internal financial reporting and is used by senior management in deciding how to allocate capital resources among business segments. We believe that investors benefit from having access to the same financial measures that our management uses in evaluating segment results. The GAAP financial measure most directly comparable to total segment gross operating margin is operating income. Our non-GAAP financial measure of total segment gross operating margin should not be considered an alternative to GAAP operating income.
We define total segment gross operating margin as consolidated operating income before: (i) depreciation, amortization and accretion expense; (ii) operating lease expenses for which we do not have the payment obligation; (iii) gains and losses on the sale of assets; and (iv) general and administrative costs. Gross operating margin is exclusive of other income and expense transactions, provision for income taxes, minority interest, extraordinary charges and the cumulative effect of change in accounting principle. Gross operating margin by segment is calculated by subtracting segment operating costs and expenses (net of the adjustments noted above) from segment revenues, with both segment totals before the elimination of intersegment and intrasegment transactions.
Segment revenues include intersegment and intrasegment transactions, which are generally based on transactions made at market-related rates. Our consolidated revenues reflect the elimination of intercompany (both intersegment and intrasegment) transactions.
We include equity earnings from unconsolidated affiliates in our measurement of segment gross operating margin and operating income. Our equity investments with industry partners are a vital component of our business strategy. They are a means by which we conduct our operations to align our interests with those of our customers and/or suppliers. This method of operation enables us to achieve favorable economies of scale relative to the level of investment and business risk assumed versus what we could accomplish on a stand-alone basis. Many of these businesses perform supporting or complementary roles to our other business operations.
Our integrated midstream energy asset system (including the midstream energy assets of our equity method investees) provides services to producers and consumers of natural gas, NGLs, crude oil and certain petrochemicals. In general, hydrocarbons enter our asset system in a number of ways, such as an offshore natural gas or crude oil pipeline, an offshore platform, a natural gas processing plant, an onshore natural gas gathering pipeline, an NGL fractionator, an NGL storage facility, or an NGL transportation or distribution pipeline.
Many of our equity investees are included within our integrated midstream asset system. For example, we have ownership interests in several offshore natural gas and crude oil pipelines. Other examples include our use of the Promix NGL fractionator to process mixed NGLs extracted by our gas plants. The fractionated NGLs we receive from Promix can then be sold in our NGL marketing activities. Given the integral nature of our equity method investees to our operations, we believe the presentation of earnings from such investees as a component of gross operating margin and operating income is meaningful and appropriate.
Historically, substantially all of our consolidated revenues were earned in the United States and derived from a wide customer base. The majority of our plant-based operations are located in Texas, Louisiana, Mississippi, New Mexico and Wyoming. Our natural gas, NGL and crude oil pipelines are located in a number of regions of the United States including (i) the Gulf of Mexico offshore Texas and
Louisiana; (ii) the south and southeastern United States (primarily in Texas, Louisiana, Mississippi and Alabama); and (iii) certain regions of the central and western United States, including the Rocky Mountains. Our marketing activities are headquartered in Houston, Texas and serve customers in a number of regions of the United States including the Gulf Coast, West Coast and Mid-Continent areas.
Consolidated property, plant and equipment and investments in and advances to unconsolidated affiliates are assigned to each segment on the basis of each assets or investments principal operations. The principal reconciling difference between consolidated property, plant and equipment and the total value of segment assets is construction-in-progress. Segment assets represent the net book carrying value of facilities and other assets that contribute to gross operating margin of that particular segment. Since assets under construction generally do not contribute to segment gross operating margin, such assets are excluded from segment asset totals until they are placed in service. Consolidated intangible assets and goodwill are assigned to each segment based on the classification of the assets to which they relate.
We consolidate the financial statements of Duncan Energy Partners with those of our own. As a result, our consolidated gross operating margin amounts include the gross operating margin amounts of Duncan Energy Partners on a 100% basis.
The following table presents our measurement of total segment gross operating margin for the periods indicated:
A reconciliation of our total segment gross operating margin to operating income and income before provision for income taxes, minority interest and the cumulative effect of change in accounting principle follows:
Information by segment, together with reconciliations to our consolidated totals, is presented in the following table:
