Note 1.  Partnership Organization and Basis of Presentation

We are a publicly traded Delaware limited partnership, the common units of which are listed on the New York Stock Exchange (“NYSE”) under the ticker symbol “EPD.”  We were formed in April 1998 to own and operate certain natural gas liquids (“NGLs”) related businesses of EPCO and are a leading North American provider of midstream energy services to producers and consumers of natural gas, NGLs, crude oil, petrochemicals and refined products. 

We conduct substantially all of our business through EPO and are owned 100% by our limited partners from an economic perspective.  Enterprise GP manages our partnership and owns a non-economic general partner interest in us.  We, Enterprise GP, EPCO and Dan Duncan LLC are affiliates under the collective common control of the DD LLC Trustees and the EPCO Trustees.  Like many publicly traded partnerships, we have no employees.  All of our management, administrative and operating functions are performed by employees of EPCO pursuant to an administrative services agreement (the “ASA”) or by other service providers.  See Note 15 for information regarding related party matters.

Our results of operations for the nine months ended September 30, 2018 are not necessarily indicative of results expected for the full year of 2018.  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 and make the information presented not misleading, certain information and footnote disclosures normally included in annual financial statements prepared in accordance with United States (“U.S.”) generally accepted accounting principles (“GAAP”) have been condensed or omitted pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”).

Note 2.  Summary of Significant Accounting Policies

Apart from those matters noted below, there have been no changes in our significant accounting policies since those reported under Note 2 of the 2017 Form 10-K.

Adoption of New Revenue Recognition Policies on January 1, 2018
For periods through December 31, 2017, we accounted for our revenue streams using Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 605, Revenue Recognition.  Under ASC 605, we recognized revenue when all of the following criteria were met: (i) persuasive evidence of an exchange arrangement existed between us and the counterparty (e.g., published tariffs), (ii) delivery of products or the rendering of services had occurred, (iii) the price of the products or the fee for services was fixed or determinable and (iv) collectibility of the amount owed by the counterparty was reasonably assured.

Effective January 1, 2018, we adopted FASB ASC 606, Revenue from Contracts with Customers, using a modified retrospective approach that applied the new revenue recognition standard to existing contracts at the implementation date and any future revenue contracts.   As such, our consolidated revenues and related financial information for periods prior to January 1, 2018 were not adjusted and continue to be reported in accordance with ASC 605.   We did not record a cumulative effect adjustment upon initially applying ASC 606 since there was no impact on partners’ equity upon adoption; however, the extent of our revenue-related disclosures has increased under the new standard.

Due to the large number of individual contracts that were in effect at the implementation date of ASC 606, we evaluated our contracts using a portfolio approach based on the types of products sold or services rendered within our business segments.  There are no material differences in the amount or timing of revenues recognized under ASC 606 when compared to ASC 605.

The core principle of ASC 606 is that a company should recognize revenue in a manner that fairly depicts the transfer of goods or services to customers in amounts that reflect the consideration the company expects to receive for those goods or services.  We apply this core principle by following five key steps outlined in ASC 606: (i) identify the contract; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the performance obligation is satisfied. Each of these steps involves management judgment and an analysis of the contract’s material terms and conditions.

Substantially all of our revenues are accounted for under ASC 606; however, to a limited extent, some revenues are accounted for under other guidance such as ASC 840, Leases, ASC 845, Nonmonetary Transactions or ASC 815, Derivatives and Hedging Activities.

Under ASC 606, we recognize revenue when or as we satisfy our performance obligation to the customer.  In situations where we have recognized revenue, but have a conditional right to consideration (based on something other than the passage of time) from the customer, we recognize unbilled revenue (a contract asset) on our consolidated balance sheet.  Unbilled revenue is reclassified to accounts receivable when we have an unconditional right of payment from the customer. Payments received from customers in advance of the period in which we satisfy a performance obligation are recorded as deferred revenue (a contract liability) on our consolidated balance sheet.

ENTERPRISE PRODUCTS PARTNERS L.P.
NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

Our revenue streams are derived from the sale of products and providing midstream services.  Revenues from the sale of products are recognized at a point in time, which represents the transfer of control (and the satisfaction of our performance obligation under the contract) to the customer.  From that point forward, the customer is able to direct the use of, and obtain substantially all the benefits from, its use of the products.  With respect to midstream services (e.g., interruptible transportation), we satisfy our performance obligations over time and recognize revenues when the services are provided and the customer receives the benefits based on an output measure of volumes redelivered.  We believe this measure is a faithful depiction of the transfer of control for midstream services since there is (i) an insignificant period of time between the receipt of customers’ volumes and their subsequent redelivery, and (ii) it is not possible to individually track and differentiate customers’ inventories as they traverse our facilities.  For stand-ready performance obligations (e.g., a storage capacity reservation contract), we recognize revenues over time on a straight-line basis as time elapses over the term of the contract. We believe that these approaches accurately depict the transfer of benefits to the customer.

Customers are invoiced for product purchases or services rendered when we have an unconditional right to consideration under the associated contract. The consideration we are entitled to invoice may be either fixed, variable or a combination of both.  Examples of fixed consideration would be fixed payments from customers under take-or-pay arrangements, storage capacity reservation agreements and firm transportation contracts. Variable consideration represents payments from customers that are based on factors that fluctuate (or vary) based on volumes, prices or both. Examples of variable consideration include interruptible transportation agreements, market-indexed product sales contracts and the value of NGLs we retain under natural gas processing agreements.  The terms of our billings are typical of the industry for the products we sell.

Under certain midstream service agreements, customers are required to provide a minimum volume over an agreed-upon period with a provision that allows the customer to make-up any volume shortfalls over an agreed-upon period (referred to as “make-up rights”).  Revenue pursuant to such agreements is initially deferred and subsequently recognized when either the make-up rights are exercised, the likelihood of the customer exercising the rights becomes remote, or we are otherwise released from the performance obligation.

Customers may contribute funds to us to help offset the construction costs related to pipeline construction activities and production well tie-ins.   Under ASC 605, these amounts were accounted for as contributions in aid of construction costs (“CIACs”) and netted against property, plant and equipment.   Under ASC 606, these receipts are recognized as additional service revenues over the term of the associated midstream services provided to the customer.

As a practical expedient, for those contracts under which we have the ability to invoice the customer in an amount that corresponds directly with the value of the performance obligation completed to date, we recognize revenue as we have the right to invoice.

See Note 9 regarding our new revenue disclosures.

Impact of ASU 2016-18 on Restricted Cash Disclosures
We adopted Accounting Standard Update (“ASU”) No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash, in the fourth quarter of 2017 and applied this ASU retrospectively to the periods presented in our Unaudited Condensed Statements of Consolidated Cash Flows.  As a result, the decrease in restricted cash of $287.7 million was excluded from net cash used in investing activities for the nine months ended September 30, 2017.

The following table provides a reconciliation of cash and cash equivalents, and restricted cash reported within the Unaudited Condensed Consolidated Balance Sheets that sum to the total of the amounts shown in the Unaudited Condensed Statements of Consolidated Cash Flows.

Restricted cash represents amounts held in segregated bank accounts by our clearing brokers as margin in support of our commodity derivative instruments portfolio and related physical purchases and sales of natural gas, NGLs, crude oil and refined products.  Additional cash may be restricted to maintain our commodity derivative instruments portfolio as prices fluctuate or margin requirements change.  The balance of restricted cash at September 30, 2018 consisted of initial margin requirements of $58.9 million and variation margin requirements of $190.0 million. The initial margin requirements will be returned to us as the related derivative instruments are settled.  See Note 14 for information regarding our derivative instruments and hedging activities.

Other Recent Accounting Developments
Lease accounting standard.  In February 2016, the FASB issued ASC 842, Leases (“ASC 842”), which requires substantially all leases to be recorded on the balance sheet. We will adopt the new standard on January 1, 2019 and apply it to (i) all new leases entered into after January 1, 2019 and (ii) all existing lease contracts as of January 1, 2019.  ASC 842 will supersede existing lease accounting guidance found under ASC 840, Leases (“ASC 840”).

The new standard introduces two lease accounting models, which result in a lease being classified as either a “finance” or “operating” lease on the basis of whether the lessee effectively obtains control of the underlying asset during the lease term.  A lease would be classified as a finance lease if it meets one of five classification criteria, four of which are generally consistent with current lease accounting guidance.  By default, a lease that does not meet the criteria to be classified as a finance lease will be deemed an operating lease.  Regardless of classification, the initial measurement of both lease types will result in the balance sheet recognition of a right-of-use (“ROU”) asset (representing a company’s right to use the underlying asset for a specified period of time) and a corresponding lease liability.  The lease liability will be recognized at the present value of the future lease payments, and the ROU asset will equal the lease liability adjusted for any prepaid rent, lease incentives provided by the lessor, and any indirect costs.

The subsequent measurement of each type of lease varies. Finance leases will be accounted for using the effective interest method.  Under this approach, a lessee will amortize the ROU asset (generally on a straight-line basis in a manner similar to depreciation) and the discount on the lease liability (as a component of interest expense).  Operating leases will result in the recognition of a single lease expense amount that is recorded on a straight-line basis (or another systematic basis, as appropriate).

ASC 842 will result in changes to the way our operating leases are recorded, presented and disclosed in our consolidated financial statements. Upon adoption of ASC 842 on January 1, 2019, we expect to recognize a ROU asset and a corresponding lease liability based on the present value of then existing operating lease obligations. In addition, there are several key accounting policy elections that we will make upon adoption of ASC 842 including:

We will not recognize ROU assets and lease liabilities for short-term leases and instead record them in a manner similar to operating leases under legacy lease accounting guidelines.  A short term lease is one with a maximum lease term of 12 months or less and does not include a purchase option the lessee is reasonably certain to exercise.

We will not assess whether any expired or existing contracts are or contain leases or the lease classification for any existing or expired leases.

The impact of adopting ASC 842 will be prospective beginning January 1, 2019.  We will not recast prior periods presented in our consolidated financial statements to reflect the new lease accounting guidance.

Based on current information, we forecast that our total remaining payment obligations under then existing operating leases will approximate $310 million (undiscounted) at January 1, 2019.   As a result, we expect to recognize an estimated $250 million ROU asset and a $250 million lease liability on our consolidated balance sheet based on discounted amounts.  These amounts would represent less than 1% of our total consolidated assets and liabilities, respectively.

Fair value measurements.  In August 2018, the FASB issued ASU 2018-13, Fair Value Measurements (Topic 820): Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement, which amends certain disclosure requirements related to fair value measurements.   The amendments will require incremental disclosures regarding uncertainties surrounding fair value measurements, including discussions of any interrelationships between significant unobservable inputs used to estimate Level 3 fair value measurements, and changes in unrealized gains and losses.  The amendments in this ASU are effective January 1, 2020, which is when we expect to apply the new requirements.  We are currently reviewing the effect of this ASU on our consolidated financial statements.

Credit losses.  In June 2016, the FASB issued ASU 2016-13, “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.”  This ASU modifies the impairment model to utilize an expected loss methodology in place of the currently used incurred loss methodology.   These changes are expected to result in the more timely recognition of losses.  The amendments in this ASU are effective January 1, 2020, which is when we expect to apply the new requirements to how the allowance for doubtful accounts is determined.  We are currently reviewing the effect of this ASU on our consolidated financial statements.

Parent-Subsidiary Guarantor Relationships
Enterprise Products Partners L.P. acts as guarantor of the consolidated debt obligations of EPO, with the exception of the remaining debt obligations of TEPPCO.  If EPO were to default on any of its guaranteed debt, Enterprise Products Partners L.P. would be responsible for full and unconditional repayment of that obligation.

Issuance of $3.0 Billion of Senior Notes in October 2018
In October 2018, EPO issued $3.0 billion aggregate principal amount of senior notes comprised of (i) $750 million principal amount of senior notes due February 2022, (ii) $1.0 billion principal amount of senior notes due October 2028 and (iii) $1.25 billion principal amount of senior notes due February 2049.  See Note 19 for information regarding this subsequent event and related use of proceeds.

Issuance of $2.0 Billion of Senior Notes and $700 Million of Junior Subordinated Notes in February 2018
In February 2018, EPO issued $2.7 billion aggregate principal amount of notes comprised of (i) $750 million principal amount of senior notes due February 2021 (“Senior Notes TT”), (ii) $1.25 billion principal amount of senior notes due February 2048 (“Senior Notes UU”) and (iii) $700 million principal amount of junior subordinated notes due February 2078 (“Junior Subordinated Notes F”).

Net proceeds from the February 2018 offerings were used by EPO for the temporary repayment of amounts outstanding under its commercial paper program, general company purposes, and the redemption of all $682.7 million outstanding aggregate principal amount of its Junior Subordinated Notes B.

Senior Notes TT were issued at 99.946% of their principal amount and have a fixed-rate interest rate of 2.80% per year.  Senior Notes UU were issued at 99.865% of their principal amount and have a fixed-rate interest rate of 4.25% per year.  Enterprise Products Partners L.P. has guaranteed the senior notes through an unconditional guarantee on an unsecured and unsubordinated basis.

The Junior Subordinated Notes F are redeemable at EPO’s option, in whole or in part, on one or more occasions, on or after February 15, 2028 at 100% of their principal amount, plus any accrued and unpaid interest thereon, and bear interest at a fixed rate of 5.375% per year through February 14, 2028.  Beginning February 15, 2028, the Junior Subordinated Notes F will bear interest at a floating rate based on a three-month LIBOR plus 2.57%, reset quarterly.  Enterprise Products Partners L.P. has guaranteed the Junior Subordinated Notes F through an unconditional guarantee on an unsecured and subordinated basis.

ENTERPRISE PRODUCTS PARTNERS L.P.
NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

Redemption of Junior Subordinated Notes
In March 2018, EPO redeemed all of the $682.7 million outstanding aggregate principal amount of its Junior Subordinated Notes B at a price equal to 100% of the principal amount of the notes being redeemed, plus all accrued and unpaid interest thereon to, but not including, the redemption date.  This redemption was funded by EPO’s issuance of senior notes and junior subordinated notes in February 2018.

In August 2018, EPO redeemed all of the $521.1 million outstanding aggregate principal amount of its Junior Subordinated Notes A at a price equal to 100% of the principal amount of the notes being redeemed, plus all accrued and unpaid interest thereon to, but not including, the redemption date.  This redemption was funded by the issuance of short-term notes under EPO’s commercial paper program.

364-Day Revolving Credit Agreement
In September 2018, EPO entered into a 364-Day Revolving Credit Agreement that replaced its prior 364-day credit facility.  The new 364-Day Revolving Credit Agreement matures in September 2019. There are currently no principal amounts outstanding under this revolving credit agreement.

Under the terms of the new 364-Day Revolving Credit Agreement, EPO may borrow up to $2.0 billion (which may be increased by up to $200 million to $2.2 billion at EPO’s election, provided certain conditions are met) at a variable interest rate for a term of up to 364 days, subject to the terms and conditions set forth therein.  To the extent that principal amounts are outstanding at the maturity date, EPO may elect to have the entire principal balance then outstanding continued as a non-revolving term loan for a period of one additional year, payable in September 2020. Borrowings under this revolving credit agreement may be used for working capital, capital expenditures, acquisitions and general company purposes.

The new 364-Day Revolving Credit Agreement contains customary representations, warranties, covenants (affirmative and negative) and events of default, the occurrence of which would permit the lenders to accelerate the maturity date of any amounts borrowed under this credit agreement.  The credit agreement also restricts EPO’s ability to pay cash distributions to its parent, Enterprise Products Partners L.P., if an event of default (as defined in the credit agreement) has occurred and is continuing at the time such distribution is scheduled to be paid or would result therefrom.

EPO’s obligations under the new 364-Day Revolving Credit Agreement are not secured by any collateral; however, they are guaranteed by Enterprise Products Partners L.P.

Increase in Amount Authorized under Commercial Paper Program
In June 2018, EPO increased the aggregate principal amount of short-term notes that it could issue (and have outstanding at any time) under its commercial paper program from $2.5 billion to $3.0 billion.  All commercial paper notes issued under the program are senior unsecured obligations of EPO that are unconditionally guaranteed by Enterprise Products Partners L.P.

Lender Financial Covenants
We were in compliance with the financial covenants of our consolidated debt agreements at September 30, 2018.

Letters of Credit
At September 30, 2018, EPO had $101.4 million of letters of credit outstanding primarily related to our commodity hedging activities.

The net cash proceeds we received from the issuance of common units during the nine months ended September 30, 2018 were used to temporarily reduce amounts outstanding under EPO’s commercial paper program and revolving credit facilities and for general company purposes, including for growth capital expenditures.

We may issue additional equity and debt securities to assist us in meeting our future liquidity requirements, including those related to capital spending.

Active Registration Statements
Universal shelf registration statement.  We have a universal shelf registration statement (the “2016 Shelf”) on file with the SEC which allows Enterprise Products Partners L.P. and EPO (each on a standalone basis) to issue an unlimited amount of equity and debt securities, respectively.  EPO issued $2.7 billion of senior and junior subordinated notes in February 2018 using the 2016 Shelf (see Note 7).  In addition, EPO issued $3.0 billion of senior notes in October 2018 using this registration statement (see Note 19).

At-the-Market (“ATM”) program.  We have a registration statement on file with the SEC covering the issuance of up to $2.54 billion of our common units in amounts, at prices and on terms to be determined by market conditions and other factors at the time of such offerings in connection with our ATM program.  Pursuant to this program, we may sell common units under an equity distribution agreement between Enterprise Products Partners L.P. and certain broker-dealers from time-to-time by means of ordinary brokers’ transactions through the NYSE at market prices, in block transactions or as otherwise agreed to with the broker-dealer parties to the agreement.  

During the nine months ended September 30, 2018, we did not issue any common units under the ATM program.  During the nine months ended September 30, 2017, we issued 21,807,726 common units under this program for aggregate gross cash proceeds of $603.1 million, resulting in total net cash proceeds of $597.3 million.

After taking into account the aggregate sales price of common units sold under the ATM program in periods prior to fiscal 2018, we have the capacity to issue additional common units under the ATM program up to an aggregate sales price of $2.54 billion.

Distribution reinvestment plan.  We have a registration statement on file with the SEC 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 our common units they own by reinvesting the quarterly cash distributions they receive from us into the purchase of additional new common units.

We issued a total of 16,073,974 common units under our DRIP during the nine months ended September 30, 2018, which generated net cash proceeds of $438.1 million.  Privately held affiliates of EPCO reinvested $206 million through the DRIP during the nine months ended September 30, 2018 (this amount being a component of the net cash proceeds presented).  During the nine months ended September 30, 2017, we issued 10,345,655 common units under our DRIP, which generated net cash proceeds of $269.9 million.  After taking into account the number of common units issued under the DRIP through September 30, 2018, we have the capacity to issue an additional 64,643,166 common units under this plan.

Employee unit purchase plan.  In addition to the DRIP, we have registration statements on file with the SEC in connection with our employee unit purchase plan (“EUPP”).  We issued 403,602 common units under our EUPP during the nine months ended September 30, 2018, which generated net cash proceeds of $11.3 million.  During the nine months ended September 30, 2017, we issued 364,934 common units under our EUPP, which generated net cash proceeds of $10.0 million.  After taking into account the number of common units issued under the EUPP through September 30, 2018, we may issue an additional 5,357,209 common units under this plan.

Common Units Issued in Connection With Employee Compensation
In February 2018, the dollar value of  discretionary employee bonus payments with respect to the year ended December 31, 2017 (less any retirement plan deductions and withholding taxes) was remitted through the issuance of an equivalent value of newly issued Enterprise common units under EPCO’s 2008 Enterprise Products Long-Term Incentive Plan (Third Amendment and Restatement) (“2008 Plan”).  We issued 1,443,586 common units, which had a value of $39.1 million, in connection with the employee bonus payments.  The compensation expense associated with this issuance of common units was recognized during the year ended December 31, 2017.

The payment of any quarterly cash distribution is subject to Board approval and management’s evaluation of our financial condition, results of operations and cash flows in connection with such payment.  Management currently expects to recommend to the Board a quarterly cash distribution of $0.4350 with respect to the fourth quarter of 2018.

Noncontrolling Interests
In June 2018, pursuant to an option agreement, an affiliate of Western Gas Partners, LP (“Western”) acquired a noncontrolling 20% equity interest in our subsidiary, Whitethorn Pipeline Company LLC (“Whitethorn”), for approximately $189.6 million in cash.  Whitethorn owns the Midland-to-ECHO pipeline, which originates at our Midland, Texas terminal and extends 416 miles to our Sealy, Texas facility. This amount is a component of contributions from noncontrolling interests as presented on our Unaudited Condensed Statement of Consolidated Cash Flows for the nine months ended September 30, 2018.

In January 2018, we announced a project to construct, own and operate an ethylene export facility, the location of which was subsequently determined to be at our Morgan’s Point facility on the Houston Ship Channel. Navigator Ethylene Terminals LLC holds a noncontrolling 50% equity interest in our consolidated subsidiary, Enterprise Navigator Ethylene Terminal LLC, that owns the export facility, which is expected to be completed in the fourth quarter of 2019.

Other
In May 2018, Apache Corporation (“Apache”) executed a long-term supply agreement with us whereby Apache would sell all of its NGL production from the Alpine High discovery to Enterprise.  Alpine High is a major hydrocarbon resource located in the Delaware Basin that encompasses rich natural gas (i.e., gas that has a high NGL content), dry natural gas and oil-bearing horizons.  In conjunction with the long-term NGL supply agreement, we granted Apache an option to acquire up to a 33% equity interest in our subsidiary that owns the Shin Oak NGL Pipeline, which is currently under construction and expected to be placed into service during the second quarter of 2019.  The option is exercisable once the pipeline is placed into commercial service and contingent upon the execution of associated definitive agreements.  In August 2018, Apache announced its intent to contribute the Shin Oak option to Altus Midstream Company, which would be majority-owned by Apache.

(1)   Revenues are accounted for under ASC 606 upon implementation at January 1, 2018.
(2)   Revenues are accounted for under ASC 605 for historical periods prior to January 1, 2018.
  

Substantially all of our revenues are derived from contracts with customers as defined within ASC 606.  In total, product sales and midstream services accounted for 85% and 15%, respectively, of our consolidated revenues for the three and nine months ended September 30, 2018.  During the three and nine months ended September 30, 2017, product sales and midstream services accounted for 84% and 16%, respectively, of our consolidated revenues.

Apart from the following information regarding natural gas processing, the description of our significant revenue streams by business segment found under Note 3 of the 2017 Form 10-K have not changed in connection with the adoption of ASC 606.

Natural gas processing utilizes service contracts that are either fee-based, commodity-based or a combination of the two. Our commodity-based contracts include keepwhole, margin-band, percent-of-liquids, percent-of-proceeds and contracts featuring a combination of commodity and fee-based terms.  When a cash fee for natural gas processing services is stipulated by a contract, we record revenue as a producer’s natural gas has been processed.

Under ASC 605, our natural gas processing business did not recognize revenue in connection with non-cash consideration (the “equity NGL volumes”) it received under percent-of-liquids and similar arrangements. We recognized revenue when the associated NGLs were delivered and sold to downstream customers under NGL marketing product sales contracts.

Under ASC 606, our natural gas processing business recognizes the value of the equity NGL volumes it receives from customers as a form of midstream service revenue. The value assigned to this non-cash consideration and related inventory is based on the market value of the equity NGLs we are entitled to when the services are performed.  We also recognize revenue, along with a corresponding cost of sales, when the NGLs are delivered and sold to downstream customers under NGL marketing product sales contracts.
23
Table of Contents
ENTERPRISE PRODUCTS PARTNERS L.P.
NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

The additional service revenue recognized for the non-cash consideration increased our total revenues by approximately 2% for the nine months ended September 30, 2018 when compared to the amount of revenues we would have recognized under ASC 605 for the quarter.  Given the rapid turnover of our inventories of NGL products each month, we do not expect a significant change in our gross operating margin from natural gas processing and related NGL marketing activities as a result of the changes required by ASC 606.

Remaining Performance Obligations
The following table presents estimated fixed consideration from contracts with customers that contain minimum volume commitments, deficiency and similar fees and the term of the contracts exceeds one year. These amounts represent the revenues we expect to recognize in future periods from these contracts at September 30, 2018.  For a significant portion of our revenue, we bill customers a contractual rate for the services provided multiplied by the amount of volume handled in a given period.  We have the right to invoice the customer in the amount that corresponds directly with the value of our performance completed to date.  Therefore, we are not required to disclose information about the variable consideration of remaining performance obligations as we recognize revenue equal to the amount that we have the right to invoice.

Impact of Change in Accounting Policy – ASC 606 Transition Disclosures
The following information and tables are provided to summarize the material impacts of adopting ASC 606 on our consolidated financial statements for the three and nine months ended September 30, 2018.

As noted previously, additional service revenue and related inventory is now recognized in connection with the equity NGL volumes (a form of non-cash consideration) we receive under natural gas processing agreements.  When the inventory is sold through our NGL marketing activities, we reflect additional cost of sales amounts within our operating costs and expenses.

Table of Contents
ENTERPRISE PRODUCTS PARTNERS L.P.
NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
Unbilled revenues have historically been presented as a component of accounts receivable on our consolidated balance sheets.  Upon implementation of ASC 606, we reclassified these amounts to “Prepaid and other current assets” since these amounts represent conditional rights to consideration.  Once we have an unconditional right to consideration, the amount is transferred to accounts receivable.

Historically, amounts received from customers as CIACs related to pipeline construction activities and production well tie-ins have been netted against property, plant and equipment on our consolidated balance sheets and presented as a cash inflow within the investing activities section of our statements of consolidated cash flows. Upon implementation of ASC 606, these amounts are now recognized as a component of midstream service revenue on our statement of operations and are a component of cash provided by operating activities as presented on our statements of consolidated cash flows.

Our operations are reported under four business segments: (i) NGL Pipelines & Services, (ii) Crude Oil Pipelines & Services, (iii) Natural Gas Pipelines & Services and (iv) Petrochemical & Refined Products Services.

Our business segments are generally organized and managed according to the types of services rendered (or technologies employed) and products produced and/or sold.  Financial information regarding these segments is evaluated regularly by our chief operating decision makers in deciding how to allocate resources and in assessing operating and financial performance.

Segment Gross Operating Margin
We evaluate segment performance based on our financial measure of gross operating margin.  Gross operating margin is an important performance measure of the core profitability of our operations and forms the basis of our internal financial reporting.  We believe that investors benefit from having access to the same financial measures that our management uses in evaluating segment results.  Gross operating margin is exclusive of other income and expense transactions, income taxes, the cumulative effect of changes in accounting principles and extraordinary charges.  Gross operating margin is presented on a 100% basis before any allocation of earnings to noncontrolling interests.

The following table presents our measurement of total segment gross operating margin for the periods presented.  The GAAP financial measure most directly comparable to total segment gross operating margin is operating income.

(1)   Since make-up rights entail a future performance obligation by the pipeline to the shipper, these receipts are recorded as deferred revenue for GAAP purposes; however, these receipts are included in gross operating margin in the period of receipt since they are nonrefundable to the shipper.
(2)   As deferred revenues attributable to make-up rights are subsequently recognized as revenue under GAAP, gross operating margin must be adjusted to remove such amounts to prevent duplication since the associated non-refundable payments were previously included in gross operating margin.

Segment assets consist of property, plant and equipment, investments in unconsolidated affiliates, intangible assets and goodwill.  The carrying values of such amounts are assigned to each segment based on each asset’s or investment’s principal operations and contribution to the gross operating margin of that particular segment.  Since construction-in-progress amounts (a component of property, plant and equipment) generally do not contribute to segment gross operating margin, such amounts are excluded from segment asset totals until the underlying assets are placed in service.  Intangible assets and goodwill are assigned to each segment based on the classification of the assets to which they relate.  The remainder of our consolidated total assets, which consist primarily of working capital assets, are excluded from segment assets since these amounts are not attributable to one specific segment (e.g. cash).

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
 
Fluctuations in our product sales revenues and related cost of sales amounts are explained in part by changes in energy commodity prices.  In general, higher energy commodity prices result in an increase in our revenues attributable to product sales; however, these higher commodity prices also increase the associated cost of sales as purchase costs rise.  The same correlation would be true in the case of lower energy commodity sales prices and purchase costs.


Note 11.   Business Combinations

On March 29, 2018, we acquired the remaining 50% member interest in our Delaware Processing joint venture for $150.6 million in cash, net of $3.9 million of cash held by the former joint venture.  As a result, Delaware Processing is now our wholly-owned consolidated subsidiary.  Delaware Processing owns a cryogenic natural gas processing facility having a capacity of 150 million cubic feet per day.  The facility is located in Reeves County, Texas and entered service in August 2016.  The acquired business serves growing production of NGL-rich natural gas from the Delaware Basin in West Texas and southern New Mexico.

The following table presents the final fair value allocation of assets acquired and liabilities assumed in the acquisition at March 29, 2018.

Prior to this acquisition, we accounted for our investment using the equity method.  On a historical pro forma basis, our revenues, costs and expenses, operating income, net income attributable to Enterprise Products Partners L.P. and earnings per unit amounts for the three and nine months ended September 30, 2018 and 2017 would not have differed materially from those we actually reported had the acquisition been completed on January 1, 2017 rather than March 29, 2018.

At March 29, 2018, our 50% equity investment in Delaware Processing was recorded at $107.0 million.  Upon acquisition of the remaining 50% member interest, our existing equity investment was remeasured to fair value resulting in the recognition of a non-cash $39.4 million gain, which is presented within Other Income on our Unaudited Condensed Consolidated Statement of Operations for the nine months ended September 30, 2018.

The results for this business will continue to be reported under the NGL Pipelines & Services business segment.

At September 30, 2018, all of the outstanding phantom unit awards were granted under the 2008 Plan.  The maximum number of common units authorized for issuance under the 2008 Plan was 45,000,000 at September 30, 2018.  This amount will automatically increase under the terms of the 2008 Plan by 5,000,000 common units on January 1, 2019 and will continue to automatically increase annually on each January 1 thereafter during the term of the 2008 Plan; provided, however, that in no event shall the maximum aggregate number exceed 70,000,000 common units.  After giving effect to awards granted under the 2008 Plan through September 30, 2018, a total of 19,103,563 additional common units were available for issuance under this plan.

EPCO serves as the general partner of four limited partnerships that were formed in 2016 (generally referred to as “Employee Partnerships”) to serve as incentive arrangements for key employees of EPCO by providing them a “profits interest” in an Employee Partnership.  The names of the Employee Partnerships are EPD PubCo Unit I L.P. (“PubCo I”), EPD PubCo Unit II L.P. (“PubCo II”), EPD PubCo Unit III L.P. (“PubCo III”) and EPD PrivCo Unit I L.P. (“PrivCo I”).

Phantom Unit Awards
Phantom unit awards allow recipients to acquire our common units (at no cost to the recipient apart from fulfilling service and other conditions) once a defined vesting period expires, subject to customary forfeiture provisions.  Phantom unit awards generally vest at a rate of 25% per year beginning one year after the grant date and are non-vested until the required service periods expire.

At September 30, 2018, substantially all of our phantom unit awards are expected to result in the issuance of common units upon vesting; therefore, the applicable awards are accounted for as equity-classified awards.  The grant date fair value of a phantom unit award is based on the market price per unit of our common units on the date of grant.  Compensation expense is recognized based on the grant date fair value, net of an allowance for estimated forfeitures, over the requisite service or vesting period.

The following table presents phantom unit award activity for the period indicated:

The 2008 Plan provides for the issuance of DERs in connection with phantom unit awards.  A DER entitles the participant to nonforfeitable cash payments equal to the product of the number of phantom unit awards outstanding for the participant and the cash distribution per common unit paid to our common unitholders.  Cash payments made in connection with DERs are charged to partners’ equity when the phantom unit award is expected to result in the issuance of common units; otherwise, such amounts are expensed.

For the EPCO group of companies, the unrecognized compensation cost associated with phantom unit awards was $130.3 million at September 30, 2018, of which our share of the cost is currently estimated to be $108.3 million.  Due to the graded vesting provisions of these awards, we expect to recognize our share of the unrecognized compensation cost for these awards over a weighted-average period of 2.1 years.

Profits Interest Awards
In 2016, EPCO Holdings Inc. (“EPCO Holdings”), a privately held affiliate of EPCO, contributed a portion of the Enterprise common units it owned to each of the Employee Partnerships.  In exchange for these contributions, EPCO Holdings was admitted as the Class A limited partner of each Employee Partnership.  Also on the applicable contribution date, certain key EPCO employees were issued Class B limited partner interests (i.e., profits interest awards) and admitted as Class B limited partners of each Employee Partnership, all without any capital contribution by such employees.  EPCO serves as the general partner of each Employee Partnership.

(1)   Represents fair market value of the Enterprise common units contributed to each Employee Partnership at the applicable contribution date.
(2)   Each quarter, the Class A limited partner in each Employee Partnership is paid a cash distribution equal to the product of (i) the number of common units owned by the Employee Partnership and (ii) the Class A Preference Return of $0.39 per unit (subject to equitable adjustment in order to reflect any equity split, equity distribution or dividend, reverse split, combination, reclassification, recapitalization or other similar event affecting such common units). To the extent that the Employee Partnership has cash remaining after making this quarterly payment to the Class A limited partner, the residual cash is distributed to the Class B limited partners on a quarterly basis.
(3)   Represents the total grant date fair value of the profits interest awards irrespective of how such costs will be allocated between us and EPCO and its privately held affiliates.
(4)   Represents our expected share of the unrecognized compensation cost at September 30, 2018. We expect to recognize our share of the unrecognized compensation cost for PubCo I, PubCo II, PubCo III and PrivCo I over a weighted-average period of 1.4 years, 2.4 years, 1.5 years and 2.4 years, respectively.

The grant date fair value of each Employee Partnership is based on (i) the estimated value (as determined using a Black-Scholes option pricing model) of such Employee Partnership’s assets that would be distributed to the Class B limited partners thereof upon liquidation and (ii) the value, based on a discounted cash flow analysis, of the residual quarterly cash amounts that such Class B limited partners are expected to receive over the life of the Employee Partnership.

The following table summarizes the assumptions we used in applying a Black-Scholes option pricing model to derive that portion of the estimated grant date fair value of the profits interest awards for each Employee Partnership:

Compensation expense attributable to the profits interest awards is based on the estimated grant date fair value of each award.  A portion of the fair value of these equity-based awards is allocated to us under the ASA as a non-cash expense.  We are not responsible for reimbursing EPCO for any expenses of the Employee Partnerships, including the value of any contributions of units made by EPCO Holdings.

Note 14.  Derivative Instruments, Hedging Activities and Fair Value Measurements

In the normal course of our business operations, we are exposed to certain risks, including changes in interest rates and commodity prices.  In order to manage risks associated with assets, liabilities and certain anticipated future transactions, we use derivative instruments such as futures, forward contracts, swaps, options and other instruments with similar characteristics.  Substantially all of our derivatives are used for non-trading activities.

On January 1, 2018, we early adopted ASU 2017-12, Derivatives and Hedging (Topic 815):  Targeted Improvements to Accounting for Hedging Activities.  Since the impact of the new guidance was not material to our consolidated financial statements, no transition adjustments were recorded. In accordance with ASU 2017-12 both the effective and ineffective portion of a cash flow hedge are initially reported as a component of accumulated other comprehensive income (loss) and reclassified into earnings when the forecasted transaction affects earnings.

Interest Rate Hedging Activities
We may utilize interest rate swaps, forward starting swaps and similar derivative instruments to manage our exposure to changes in interest rates charged on borrowings under certain consolidated debt agreements.  This strategy may be used in controlling our overall cost of capital associated with such borrowings.

The following table summarizes our portfolio of forward starting swaps at September 30, 2018:

Cash flow hedge

As a result of market conditions in January 2018, we elected to terminate $100 million notional amount of the forward starting swaps that were outstanding at December 31, 2017, which resulted in cash proceeds totaling $1.5 million for the first quarter of 2018.

In October 2018, we elected to terminate the remaining $175 million notional amount of forward starting swaps outstanding at September 30, 2018 in connection with the issuance of $3.0 billion aggregate principal amount of senior notes (see Note 19). We received cash proceeds totaling $20.6 million in connection with these terminations.

We sold swaptions related to our interest rate hedging activities that resulted in the recognition of $7.2 million, $11.8 million and $10.4 million of cash gains that were reflected as a reduction in interest expense for the first, second and third quarters of 2018, respectively.

Commodity Hedging Activities
The prices of natural gas, NGLs, crude oil, petrochemicals and refined products are subject to fluctuations in response to changes in supply and demand, market conditions and a variety of additional factors that are beyond our control.  In order to manage such price risks, we enter into commodity derivative instruments such as physical forward contracts, futures contracts, fixed-for-float swaps and basis swaps.  

At September 30, 2018, our predominant commodity hedging strategies consisted of (i) hedging anticipated future purchases and sales of commodity products associated with transportation, storage and blending activities, (ii) hedging natural gas processing margins and (iii) hedging the fair value of commodity products held in inventory.

ENTERPRISE PRODUCTS PARTNERS L.P.
NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
 
The objective of our anticipated future commodity purchases and sales hedging program is to hedge the margins of certain transportation, storage, blending and operational activities by locking in purchase and sale prices through the use of derivative instruments and related contracts.

The objective of our natural gas processing hedging program is to hedge an amount of earnings associated with these activities.  We achieve this objective by executing fixed-price sales for a portion of our expected equity NGL production using derivative instruments and related contracts.  For certain natural gas processing contracts, the hedging of expected equity NGL production also involves the purchase of natural gas for plant thermal reduction, which is hedged using derivative instruments and related contracts.

The objective of our inventory hedging program is to hedge the fair value of commodity products currently held in inventory by locking in the sales price of the inventory through the use of derivative instruments and related contracts.

Derivative assets and liabilities recorded on our Unaudited Condensed Consolidated Balance Sheets are presented on a gross-basis and determined at the individual transaction level.  The tabular presentation above provides a means for comparing the gross amount of derivative assets and liabilities, excluding associated accounts payable and receivable, to the net amount that would likely be receivable or payable under a default scenario based on the existence of rights of offset in the respective derivative agreements.  Any cash collateral paid or received is reflected in these tables, but only to the extent that it represents variation margins.  Any amounts associated with derivative prepayments or initial margins that are not influenced by the derivative asset or liability amounts or those that are determined solely on their volumetric notional amounts are excluded from these tables.

Over the next twelve months, we expect to reclassify $37.4 million of losses attributable to interest rate derivative instruments from accumulated other comprehensive loss to earnings as an increase in interest expense.  Likewise, we expect to reclassify $194.5 million of losses attributable to commodity derivative instruments from accumulated other comprehensive loss to earnings, $192.4 million as a decrease in revenue and $2.1 million as an increase in operating costs and expenses.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

The values for commodity derivatives are presented before and after the application of Rule 814 of the Chicago Mercantile Exchange (“CME”), which deems that financial instruments cleared by the CME are settled daily in connection with variation margin payments.  As a result of this exchange rule, CME-related derivatives are considered to have no fair value at the balance sheet date for financial reporting purposes; however, the derivatives remain outstanding and subject to future commodity price fluctuations until they are settled in accordance with their contractual terms.  Derivative transactions cleared on exchanges other than the CME (e.g., the Intercontinental Exchange or ICE) continue to be reported on a gross basis.

With respect to commodity derivatives, we believe forward commodity prices are the most significant unobservable inputs in determining our Level 3 recurring fair value measurements at September 30, 2018.  In general, changes in the price of the underlying commodity increases or decreases the fair value of a commodity derivative depending on whether the derivative was purchased or sold.  We generally expect changes in the fair value of our derivative instruments to be offset by corresponding changes in the fair value of our hedged exposures.

Impairment charges are primarily a component of “Operating costs and expenses” on our Unaudited Condensed Statements of Consolidated Operations.

Total asset impairment and related charges during the nine months ended September 30, 2018 and 2017 include impairment charges attributable to the write-down of spare parts classified as current assets of $0.8 million and $12.0 million, respectively.

Other Fair Value Information
The carrying amounts of cash and cash equivalents (including restricted cash balances), accounts receivable, commercial paper notes and accounts payable approximate their fair values based on their short-term nature.  The estimated total fair value of our fixed-rate debt obligations was $23.84 billion and $23.47 billion at September 30, 2018 and December 31, 2017, respectively.  The aggregate carrying value of these debt obligations was $23.15 billion and $21.48 billion at September 30, 2018 and December 31, 2017, respectively.  These values are based on quoted market prices for such debt or debt of similar terms and maturities (Level 2), our credit standing and the credit standing of our counterparties.  Changes in market rates of interest affect the fair value of our fixed-rate debt.  The carrying values of our variable-rate long-term debt obligations approximate their fair values since the associated interest rates are market-based.  We do not have any long-term investments in debt or equity securities recorded at fair value.

Relationship with EPCO and Affiliates
We have an extensive and ongoing relationship with EPCO and its privately held affiliates (including Enterprise GP, our general partner), which are not a part of our consolidated group of companies.  

At September 30, 2018, EPCO and its privately held affiliates (including Dan Duncan LLC and certain Duncan family trusts) beneficially owned the following limited partner interests in us:

 of Units
Percentage of
Total Units
Outstanding
697,260,378

Of the total number of units held by EPCO and its privately held affiliates, 108,222,618 have been pledged as security under the credit facilities of EPCO and its privately held affiliates at September 30, 2018.  These credit facilities contain customary and other events of default, including defaults by us and other affiliates of EPCO.  An event of default, followed by a foreclosure on the pledged collateral, could ultimately result in a change in ownership of these units and affect the market price of our common units.

We and Enterprise GP are both separate legal entities apart from each other and apart from EPCO and its other affiliates, with assets and liabilities that are also separate from those of EPCO and its other affiliates.  EPCO and its privately held affiliates depend on the cash distributions they receive from us and other investments to fund their other activities and to meet their debt obligations.  During the nine months ended September 30, 2018 and 2017, we paid EPCO and its privately held affiliates cash distributions totaling $867.4 million and $835.5 million, respectively.

From time-to-time, EPCO and its privately held affiliates elect to purchase additional common units under our DRIP and ATM program.  During the nine months ended September 30, 2018, privately held affiliates of EPCO reinvested $206 million through the DRIP.  See Note 8 for additional information regarding our DRIP.

We have no employees.  All of our operating functions and general and administrative support services are provided by employees of EPCO pursuant to the ASA or by other service providers.  The following table presents our related party costs and expenses attributable to the ASA with EPCO for the periods indicated:

Note 16.  Commitments and Contingencies

Litigation
As part of our normal business activities, we may be named as defendants in legal proceedings, including those arising from regulatory and environmental matters.  Although we are insured against various risks to the extent we believe it is prudent, there is no assurance that the nature and amount of such insurance will be adequate, in every case, to fully indemnify us against losses arising from future legal proceedings.  We will vigorously defend the partnership in litigation matters.

Management has regular quarterly litigation reviews, including updates from legal counsel, to assess the possible need for accounting recognition and disclosure of these contingencies.  We accrue an undiscounted liability for those contingencies where the loss is probable and the amount can be reasonably estimated.  If a range of probable loss amounts can be reasonably estimated and no amount within the range is a better estimate than any other amount, then the minimum amount in the range is accrued.

We do not record a contingent liability when the likelihood of loss is probable but the amount cannot be reasonably estimated or when the likelihood of loss is believed to be only reasonably possible or remote.  For contingencies where an unfavorable outcome is reasonably possible and the impact would be material to our consolidated financial statements, we disclose the nature of the contingency and, where feasible, an estimate of the possible loss or range of loss.  Based on a consideration of all relevant known facts and circumstances, we do not believe that the ultimate outcome of any currently pending litigation directed against us will have a material impact on our consolidated financial statements either individually at the claim level or in the aggregate.

At September 30, 2018 and December 31, 2017, our accruals for litigation contingencies were $0.5 million and $4.5 million, respectively, and recorded in our Unaudited Condensed Consolidated Balance Sheets as a component of “Other current liabilities.”  Our evaluation of litigation contingencies is based on the facts and circumstances of each case and predicting the outcome of these matters involves uncertainties.  In the event the assumptions we use to evaluate these matters change in future periods or new information becomes available, we may be required to record additional accruals.  In an effort to mitigate expenses associated with litigation, we may settle legal proceedings out of court.

ETP Matter.  In connection with a proposed pipeline project, we and ETP signed a non-binding letter of intent in April 2011 that disclaimed any partnership or joint venture related to such project absent executed definitive documents and board approvals of the respective companies.  Definitive agreements were never executed and board approval was never obtained for the potential pipeline project.  In August 2011, the proposed pipeline project was cancelled due to a lack of customer support.

In September 2011, ETP filed suit against us and a third party in connection with the cancelled project alleging, among other things, that we and ETP had formed a “partnership.”  The case was tried in the District Court of Dallas County, Texas, 298th Judicial District.  While we firmly believe, and argued during our defense, that no agreement was ever executed forming a legal joint venture or partnership between the parties, the jury found that the actions of the two companies, nevertheless, constituted a legal partnership.  As a result, the jury found that ETP was wrongfully excluded from a subsequent pipeline project involving a third party, and awarded ETP $319.4 million in actual damages on March 4, 2014.  On July 29, 2014, the court entered judgment against us in an aggregate amount of $535.8 million, which included (i) $319.4 million as the amount of actual damages awarded by the jury, (ii) an additional $150.0 million in disgorgement for the alleged benefit we received due to a breach of fiduciary duties by us against ETP and (iii) prejudgment interest in the amount of $66.4 million.  The court also awarded post-judgment interest on such aggregate amount, to accrue at a rate of 5%, compounded annually.

We filed our Brief of the Appellant in the Court of Appeals for the Fifth District of Dallas, Texas on March 30, 2015 and ETP filed its Brief of Appellees on June 29, 2015.  We filed our Reply Brief of Appellant on September 18, 2015.  Oral argument was conducted on April 20, 2016, and the case was then submitted to the Court of Appeals for its consideration.  On July 18, 2017, a panel of the Court of Appeals issued a unanimous opinion reversing the trial court’s judgment as to all of ETP’s claims against us, rendering judgment that ETP take nothing on those claims, and affirming our counterclaim against ETP of approximately $0.8 million, plus interest.

On December 27, 2017, ETP filed its Petition for Review with the Supreme Court of Texas and we filed our Response to the Petition for Review on February 26, 2018.  On June 8, 2018, the Supreme Court of Texas requested that the parties file briefs on the merits, and the parties are drafting their respective submittals.  As of September 30, 2018, we have not recorded a provision for this matter as management continues to believe that payment of damages by us in this case is not probable. We continue to monitor developments involving this matter.

PDH Litigation.  In July 2013, we executed a contract with Foster Wheeler USA Corporation (“Foster Wheeler”) pursuant to which Foster Wheeler was to serve as the general contractor responsible for the engineering, procurement, construction and installation of our propane dehydrogenation (“PDH”) facility.  In November 2014, Foster Wheeler was acquired by an affiliate of AMEC plc to form Amec Foster Wheeler plc, and Foster Wheeler is now known as Amec Foster Wheeler USA Corporation (“AFW”).  In December 2015, Enterprise and AFW entered into a transition services agreement under which AFW was partially terminated from the PDH project.  In December 2015, Enterprise engaged a second contractor, Optimized Process Designs LLC, to complete the construction and installation of the PDH facility.

On September 2, 2016, we terminated AFW for cause and filed a lawsuit in the 151st Judicial Civil District Court of Harris County, Texas against AFW and its parent company, Amec Foster Wheeler plc, asserting claims for breach of contract, breach of warranty, fraudulent inducement, string-along fraud, gross negligence, professional negligence, negligent misrepresentation and attorneys’ fees.  We intend to diligently prosecute these claims and seek all direct, consequential, and exemplary damages to which we may be entitled.

Contractual Obligations
Scheduled Maturities of Debt.  We have long-term and short-term payment obligations under debt agreements.  See Note 7 for additional information regarding our scheduled future maturities of debt principal.

Operating Lease Obligations.  Consolidated lease and rental expense was $27.6 million and $26.0 million during the three months ended September 30, 2018 and 2017, respectively.  For the nine months ended September 30, 2018 and 2017, consolidated lease and rental expense was $79.0 million and $78.1 million, respectively.  Our operating lease commitments at September 30, 2018 did not differ materially from those reported in our 2017 Form 10-K.

Purchase Obligations.  During the first nine months of 2018, we entered into long-term product purchase commitments for crude oil with third party suppliers in order to meet future physical delivery obligations on our various systems.  On a combined basis, these agreements increased our estimated long-term purchase obligations by approximately $1.2 billion over the next five years and $1.8 billion overall.  Apart from these new agreements, there have been no other material changes in our consolidated purchase obligations since those reported in our 2017 Form 10-K. 

Liquidity Option Agreement
We entered into a put option agreement (the “Liquidity Option Agreement” or “Liquidity Option”) with Oiltanking Holding Americas, Inc. (“OTA”) and Marquard & Bahls AG, a German corporation and the ultimate parent company of OTA (“M&B”), in connection with the first step of the Oiltanking acquisition (“Step 1”). Under the Liquidity Option Agreement, we granted M&B the option to sell to us 100% of the issued and outstanding capital stock of OTA at any time within a 90-day period commencing on February 1, 2020.  If the Liquidity Option is exercised during this period, we would indirectly acquire the Enterprise common units then owned by OTA, currently 54,807,352 units, and assume all future income tax obligations associated with (i) owning common units encumbered by entity-level taxes of a U.S. corporation and (ii) any associated  net deferred taxes.  If we assume net deferred tax liabilities that exceed the then current book value of the Liquidity Option liability at the exercise date, we will recognize expense for the difference.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

The carrying value of the Liquidity Option Agreement, which is a component of “Other long-term liabilities” on our Unaudited Condensed Consolidated Balance Sheet, was $368.8 million and $333.9 million at September 30, 2018 and December 31, 2017, respectively.  The fair value of the Liquidity Option, at any measurement date, represents the present value of estimated federal and state income tax payments that we believe a market participant would incur on the future taxable income of OTA. We expect that OTA’s taxable income would, in turn, be based on an allocation of our partnership’s taxable income to the common units then held by OTA and reflect any tax planning we believe could be employed.

Our valuation estimate for the Liquidity Option at September 30, 2018 is based on several inputs that are not observable in the market (i.e., Level 3 inputs) such as the following:

OTA remains in existence (i.e., is not dissolved and its assets sold) between one and 30 years following exercise of the Liquidity Option, depending on the liquidity preference of its owner. An equal probability that OTA would be dissolved was assigned to each year in the 30-year forecast period;

Forecasted annual growth rates of Enterprise’s taxable earnings before interest, taxes, depreciation and amortization ranging from 2.1% to 7.2%;

OTA’s ownership interest in Enterprise common units is assumed to be diluted over time in connection with Enterprise’s issuance of equity for general company reasons.  For purposes of the valuation at September 30, 2018, we used ownership interests ranging from 1.8% to 2.5%;

OTA pays an aggregate federal and state income tax rate of 24% on its taxable income; and

A discount rate of 7.9% based on our weighted-average cost of capital at September 30, 2018.

Furthermore, our valuation estimate incorporates probability-weighted scenarios reflecting the likelihood that M&B may elect to divest a portion of the Enterprise common units held by OTA prior to exercise of the option.  At September 30, 2018, based on these scenarios, we expect that OTA would own approximately 93% of the 54,807,352 Enterprise common units it received in Step 1 when the option period begins in February 2020.  If our valuation estimate assumed that OTA owned all of the Enterprise common units it received in Step 1 at the time of exercise (and all other inputs remained the same), the estimated fair value of the Liquidity Option liability at September 30, 2018 would have increased by $27.2 million.

Changes in the fair value of the Liquidity Option are recognized in earnings as a component of other income (expense) on our Unaudited Condensed Statements of Consolidated Operations.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

Note 19.  Subsequent Events

Issuance of $3.0 Billion of Senior Notes in October 2018
In October 2018, EPO issued $3.0 billion aggregate principal amount of senior notes comprised of (i) $750 million principal amount of senior notes due February 2022 (“Senior Notes VV”), (ii) $1.00 billion principal amount of senior notes due October 2028 (“Senior Notes WW”) and (iii) $1.25 billion principal amount of senior notes due February 2049 (“Senior Notes XX”).  Net proceeds from this offering were used by EPO for the temporary repayment of amounts outstanding under its commercial paper program and for general company purposes, including for growth capital expenditures.

Senior Notes VV were issued at 99.985% of their principal amount and have a fixed-rate interest rate of 3.50% per year.  Senior Notes WW were issued at 99.764% of their principal amount and have a fixed-rate interest rate of 4.15% per year.  Senior Notes XX were issued at 99.390% of their principal amount and have a fixed-rate interest rate of 4.80% per year.  Enterprise Products Partners L.P. has guaranteed the senior notes through an unconditional guarantee on an unsecured and unsubordinated basis.

Sale of Red River System in October 2018
On October 1, 2018, we closed on the sale of our Red River System and associated crude oil linefill for approximately $135 million, of which $10.5 million was received as a deposit in the third quarter of 2018.   The Red River System gathers and transports crude oil from North Texas and southern Oklahoma for delivery to local refineries and pipeline interconnects for further transportation to the Cushing hub and Gulf Coast.   As of September 30, 2018, the carrying value of these assets totaled $109.6 million, which was classified as held-for-sale primarily within other current assets on our Unaudited Consolidated Balance Sheet.

The following information should be read in conjunction with our Unaudited Condensed Consolidated Financial Statements and accompanying Notes included in this quarterly report on Form 10-Q and the Audited Consolidated Financial Statements and related Notes, together with our discussion and analysis of financial position and results of operations, included in our annual report on Form 10-K for the year ended December 31, 2017 (the “2017 Form 10-K”), as filed on February 28, 2018 with the U.S. Securities and Exchange Commission (“SEC”).  Our financial statements have been prepared in accordance with generally accepted accounting principles (“GAAP”) in the United States (“U.S.”).

Key References Used in this Management’s Discussion and Analysis

Unless the context requires otherwise, references to “we,” “us,” “our,” “Enterprise” or “Enterprise Products Partners” are intended to mean the business and operations of Enterprise Products Partners L.P. and its consolidated subsidiaries.  References to “EPO” mean Enterprise Products Operating LLC, which is a wholly owned subsidiary of Enterprise, and its consolidated subsidiaries, through which Enterprise Products Partners L.P. conducts its business.  Enterprise is managed by its general partner, Enterprise Products Holdings LLC (“Enterprise GP”), which is a wholly owned subsidiary of Dan Duncan LLC, a privately held Texas limited liability company.

The membership interests of Dan Duncan LLC are owned by a voting trust, the current trustees (“DD LLC Trustees”) of which are: (i) Randa Duncan Williams, who is also a director and Chairman of the Board of Directors (the “Board”) of Enterprise GP; (ii) Richard H.

Cautionary Statement Regarding Forward-Looking Information

This quarterly report on Form 10-Q contains various forward-looking statements and information that are based on our beliefs and those of our general partner, as well as assumptions made by us and information currently available to us.  When used in this document, words such as “anticipate,” “project,” “expect,” “plan,” “seek,” “goal,” “estimate,” “forecast,” “intend,” “could,” “should,” “would,” “will,” “believe,” “may,” “potential” and similar expressions and statements regarding our plans and objectives for future operations are intended to identify forward-looking statements.  Although we and our general partner believe that our expectations reflected in such forward-looking statements are reasonable, neither we nor our general partner can give any assurances that such expectations will prove to be correct.  Forward-looking statements are subject to a variety of risks, uncertainties and assumptions as described in more detail under Part I, Item 1A of our 2017 Form 10-K and within Part II, Item 1A of this quarterly report.  If one or more of these risks or uncertainties materialize, or if underlying assumptions prove incorrect, our actual results may vary materially from those anticipated, estimated, projected or expected.  You should not put undue reliance on any forward-looking statements.  The forward-looking statements in this quarterly report speak only as of the date hereof.  Except as required by federal and state securities laws, we undertake no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or any other reason.

Overview of Business

We are a publicly traded Delaware limited partnership, the common units of which are listed on the New York Stock Exchange (“NYSE”) under the ticker symbol “EPD.”  We were formed in April 1998 to own and operate certain natural gas liquids (“NGLs”) related businesses of EPCO and are a leading North American provider of midstream energy services to producers and consumers of natural gas, NGLs, crude oil, petrochemicals and refined products. 

Our integrated midstream energy asset network links producers of natural gas, NGLs and crude oil from some of the largest supply basins in the U.S., Canada and the Gulf of Mexico with domestic consumers and international markets.  Our midstream energy operations currently include: natural gas gathering, treating, processing, transportation and storage; NGL transportation, fractionation, storage, and export and import terminals (including those used to export liquefied petroleum gases, or “LPG,” and ethane); crude oil gathering, transportation, storage, and export and import terminals; petrochemical and refined products transportation, storage, export and import terminals, and related services; and a marine transportation business that operates primarily on the U.S. inland and Intracoastal Waterway systems.  Our assets currently include approximately 50,000 miles of pipelines; 260 MMBbls of storage capacity for NGLs, crude oil, petrochemicals and refined products; and 14 Bcf of natural gas storage capacity.  

We conduct substantially all of our business through EPO and are owned 100% by our limited partners from an economic perspective.  Enterprise GP manages our partnership and owns a non-economic general partner interest in us.  We, Enterprise GP, EPCO and Dan Duncan LLC are affiliates under the collective common control of the DD LLC Trustees and the EPCO Trustees.  Like many publicly traded partnerships, we have no employees.  All of our management, administrative and operating functions are performed by employees of EPCO pursuant to an administrative services agreement (the “ASA”) or by other service providers.

Our operations are reported under four business segments:  (i) NGL Pipelines & Services, (ii) Crude Oil Pipelines & Services, (iii) Natural Gas Pipelines & Services and (iv) Petrochemical & Refined Products Services.  Our business segments are generally organized and managed according to the types of services rendered (or technologies employed) and products produced and/or sold.

Each of our business segments benefits from the supporting role of our related marketing activities.  The main purpose of our marketing activities is to support the utilization and expansion of assets across our midstream energy asset network by increasing the volumes handled by such assets, which results in additional fee-based earnings for each business segment.  In performing these support roles, our marketing activities also seek to participate in supply and demand opportunities as a supplemental source of gross operating margin, a non-generally accepted accounting principle (“non-GAAP”) financial measure, for the partnership.  The financial results of our marketing efforts fluctuate due to changes in volumes handled and overall market conditions, which are influenced by current and forward market prices for the products bought and sold.

We provide investors access to additional information regarding our partnership, including information relating to our governance procedures and principles, through our website, www.enterpriseproducts.com.

Significant Recent Commercial Developments

Enterprise Increasing NGL Fractionation Capacity in Texas and Louisiana
The demand for NGL fractionation capacity continues to expand as producers in domestic shale plays like the Permian Basin, the Eagle Ford and Denver-Julesburg (“DJ”) Basin seek market access and end users require supply assurance.

In light of this ongoing trend, we will construct a new NGL fractionation facility located adjacent to our existing NGL fractionation complex at Mont Belvieu, Texas.  The new facility will consist of two fractionation trains capable of processing 300 MBPD of NGLs.  The first of the two fractionation trains will have a nameplate capacity of 150 MBPD and is scheduled to be completed and begin service in the first quarter of 2020. The second of these fractionation trains will also have a nameplate capacity of 150 MBPD and is scheduled to be completed and begin service in the second quarter of 2020.

In November 2018, we announced a series of projects designed to provide us with an additional 55 MBPD of NGL fractionation capacity in Texas and Louisiana.  As part of this initiative, we plan to optimize our Shoup NGL fractionator located in Nueces County, Texas by expanding and repurposing a portion of our South Texas pipelines.  This project would entail the construction of approximately 21 miles of new pipeline along with the conversion of approximately 65 miles of existing natural gas pipeline to NGL service, which will allow us to supply Shoup with an additional 25 MBPD of NGL volumes.  The expanded pipeline capacity is expected to be available in the third quarter of 2019.

In Louisiana, we plan to restart our Tebone NGL fractionator located in Ascension Parish. Tebone has a fractionation capacity of 30 MBPD and is connected by pipeline to each of our Louisiana natural gas processing plants, as well as our NGL fractionation and storage hub in Mont Belvieu.  The resumption of service at Tebone, which is expected in the first quarter of 2019, will complement our Norco and Promix NGL fractionators and provide another option for NGLs delivered to Mont Belvieu.

The construction of our new 300 MBPD NGL fractionation facility at Mont Belvieu, the optimization of our Shoup facility and restart of our Tebone fractionator highlights the flexibility of our integrated midstream network and provides a timely, efficient and cost-effective solution for accommodating growing production from domestic shale basins.  Once these projects are complete and service begins, our NGL fractionation capacity would increase to an aggregate 1 MMBPD in the Mont Belvieu area, and approximately 1.5 MMBPD company-wide.

Enterprise Begins Construction of Seventh Natural Gas Processing Plant in Delaware Basin;
   Second Train at Orla Natural Gas Processing Plant Begins Service
In October 2018, we announced that construction of our Mentone cryogenic natural gas processing plant had commenced.  The Mentone plant, which is located in Loving County, Texas, is expected to have the capacity to process 300 MMcf/d of natural gas and extract in excess of 40 MBPD of NGLs.  The project is scheduled to be completed in the first quarter of 2020 and is supported by a long-term acreage dedication agreement.  The Mentone plant further extends our presence in the growing Delaware Basin and provides access to our fully integrated midstream asset network serving domestic and international markets. To support the development of Mentone, we are constructing approximately 70 miles of gathering and residue pipelines and expanding compression capabilities.  These projects will allow the Mentone plant to link to our NGL system, including the Shin Oak pipeline scheduled for completion in the second quarter of 2019, as well as our Texas Intrastate natural gas pipeline network.  We will own and operate the Mentone facility and related infrastructure.

The Mentone plant will complement our existing cryogenic natural gas processing plant located near Orla, Texas in Reeves County.   In May 2018 and October 2018, we commenced operations of the first and second processing trains (Orla I and Orla II), respectively, at the facility.  A third processing train (Orla III) is scheduled to be completed in the third quarter of 2019.  We own and operate the Orla facility.  In conjunction with the start-up of Orla I, we placed into service approximately 70 miles of natural gas pipelines that connect the Orla facility to our Texas Intrastate System.   We also placed into service a 30-mile extension of our NGL system that provides producers at the Orla facility with NGL takeaway capacity and direct access to our integrated network of downstream NGL assets.

When fully completed, the Orla and Mentone plants will provide us with an aggregate 1.3 Bcf/d of natural gas processing capacity and 195 MBPD of NGL production in the Delaware Basin.

CME Group Launches Physical West Texas Intermediate (“WTI”) Houston Crude Oil Futures Contract
In September 2018, the CME Group, a leading derivatives marketplace, announced that suppliers, refiners and end users of U.S. crude oil have a new way to price and hedge WTI light sweet crude oil (“WTI Light”) in Houston, Texas.  Participants will have the flexibility to make or take delivery of WTI Light at our ECHO terminal, Enterprise Hydrocarbons Terminal (“EHT”) or pipeline interconnect at Genoa Junction. The new futures contracts received regulatory approval in October 2018 and are listed with and subject to the rules of the New York Mercantile Exchange (“NYMEX”), beginning with the January 2019 contract month.

Enterprise Expanding LPG Capacity at Houston Ship Channel Terminal
In September 2018, we announced a project to increase LPG loading capacity at EHT by 175 MBPD, or approximately 5 MMBbls per month.  The expansion will bring our total LPG export capacity at EHT to 720 MBPD, or approximately 21 MMBbls per month. Upon completion of this expansion project, EHT will have the capability to load up to six Very Large Gas Carrier (“VLGC”) vessels simultaneously, while maintaining the option to switch between loading propane and butane. Once operational, the expansion will allow EHT to load a single VLGC in less than 24 hours, creating greater efficiencies and cost savings for our customers. The incremental loading capacity is expected to be available in the third quarter of 2019.

Enterprise to Develop Offshore Texas Crude Oil Export Terminal
In July 2018, management announced that we are in the planning stage to develop a crude oil export terminal located offshore along the Texas Gulf Coast.  The terminal would be capable of fully loading Very Large Crude Carrier (“VLCC”) marine tankers, which have capacities of approximately 2 MMBbls and provide the most efficient and cost-effective solution to export crude oil to the largest international markets in Asia and Europe.   We have started front-end engineering and design work for the terminal and preparing applications for regulatory permitting.   Based on initial designs, the project could include approximately 80 miles of 42-inch diameter pipeline extending from onshore facilities to an offshore terminal loading crude oil for export at approximately 85 thousand barrels per hour.   A final investment decision for the project will be subject to receiving state and federal permits and customer demand.

Seaway Commences Loading Services for VLCC Tankers
In June 2018, we commenced the loading of VLCC tankers using a combination of our jointly owned Seaway marine terminal located in Texas City, Texas and lightering operations in the Gulf of Mexico.  Approximately 1.1 MMBbls of crude oil were loaded onto the FPMC C Melody at the Texas City marine terminal and the remainder of the crude oil shipment was loaded on the VLCC in a lightering zone in the Gulf of Mexico.  The FPMC C Melody, chartered by Vitol, Inc., was the first VLCC to be loaded at a Texas port.  The Seaway marine terminal features two docks, a 45-foot draft, an overall length of 1,125 feet, a 220-foot beam (width) and the capacity to load crude oil at a rate of 35 thousand barrels per hour.

In July 2018, we completed a second partial loading of a VLCC tanker at the Seaway terminal. The Eagle Victoria loaded approximately 1.1 MMBbls at the terminal, with the balance completed using lightering vessels in the Gulf of Mexico.  Additional VLCC tankers are expected to be loaded during the fourth quarter of 2018.

Affiliate of Western Gas Acquires 20% Ownership Interest in Midland-to-ECHO Pipeline
In June 2018, pursuant to an option agreement, an affiliate of Western Gas Partners, LP (“Western”) acquired a noncontrolling 20% equity interest in our subsidiary, Whitethorn Pipeline Company LLC (“Whitethorn”), for approximately $189.6 million in cash.  Whitethorn owns the Midland-to-ECHO Pipeline, which originates at our Midland, Texas terminal and extends 416 miles to our Sealy, Texas facility. Volumes arriving at Sealy are then transported to our ECHO terminal using our Rancho II pipeline, which is a component of our South Texas Crude Oil Pipeline System. Once all infrastructure is complete, the Midland-to-ECHO Pipeline will provide Permian Basin producers with the ability to transport multiple grades of crude oil, including WTI, Light WTI, West Texas Sour and condensate, to Gulf Coast markets. As a result of infrastructure completed in the second quarter of 2018 as well as operating enhancements, the pipeline’s transportation capacity is now approximately 575 MBPD.  We report the pipeline’s transportation volumes on a net basis that reflects our 80% interest.

Upon closing of the transaction whereby Western acquired its 20% equity interest in Whitethorn, we credited Western for 20% of the pipeline’s earnings since it was placed into service in November 2017.  We paid Western $45.7 million in June 2018 to settle this obligation.

Apache Dedicates Alpine High NGLs to Enterprise
In May 2018, Apache Corporation (“Apache”) executed a long-term supply agreement with us whereby Apache would sell all of its NGL production from the Alpine High discovery to us.  Alpine High is a major hydrocarbon resource located in the Delaware Basin that encompasses rich natural gas (i.e., gas that has a high NGL content), dry natural gas and oil-bearing horizons.  Apache holds approximately 336,000 net acres in the Alpine High discovery.  Enterprise has committed to purchase up to 205 MBPD of NGLs from Apache over the initial ten year term of the supply agreement, the term of which may be extended at the consent of the parties.

In conjunction with the long-term NGL supply agreement, we granted Apache an option to acquire up to a 33% equity interest in our subsidiary that owns the Shin Oak NGL Pipeline, which is currently under construction and expected to be placed into service during the second quarter of 2019.  The option is exercisable once the pipeline is placed into commercial service. The Shin Oak NGL Pipeline is designed to transport growing NGL production from the Permian Basin, which includes the Alpine High discovery, to our NGL fractionation and storage complex located in Mont Belvieu, Texas.  The Shin Oak NGL Pipeline is expected to have an initial design capacity of 550 MBPD.  In August 2018, Apache announced its intent to contribute the Shin Oak option to Altus Midstream Company, which would be majority-owned by Apache.

Construction Begins on Ethylene Export Dock
In May 2018, we announced that construction of our ethylene export terminal located at Morgan’s Point on the Houston Ship Channel had commenced.  The terminal will have the capacity to export approximately 2.2 billion pounds of ethylene per year. Refrigerated storage for 66 million pounds of ethylene is being constructed on-site and will provide the capability to load ethylene at rates of 2.2 million pounds per hour. The project, which is underwritten by long-term contracts with customers, is expected to be completed in the fourth quarter of 2019.

Enterprise and Energy Transfer form Joint Venture to Restore Service on Old Ocean Pipeline
In May 2018, we announced the formation of a 50/50 joint venture with Energy Transfer Partners, L.P. (“Energy Transfer” or “ETP”) to resume full service on the Old Ocean natural gas pipeline owned by ETP.  The 24-inch diameter Old Ocean Pipeline originates in Maypearl, Texas in Ellis County and extends south approximately 240 miles to Sweeny, Texas in Brazoria County.  ETP serves as operator of the pipeline.

The Old Ocean Pipeline resumed limited service in the second quarter of 2018.  If fully reconstituted, the Old Ocean Pipeline is expected to provide natural gas transportation capacity of up to 160 MMcf/d by the end of 2018. In addition, both parties are expanding their jointly owned North Texas 36-inch diameter pipeline, which is a component of our Texas Intrastate System, to provide additional natural gas takeaway capacity of 150 MMcf/d from West Texas, including deliveries into the Old Ocean Pipeline.  The North Texas Pipeline expansion project is expected to be complete by late fourth quarter of 2018.

The resumption of full service on the Old Ocean Pipeline and expansion of the North Texas Pipeline are expected to provide producers with additional takeaway capacity to accommodate growing natural gas production from the Delaware and Midland Basins.

Expansions of our Front Range and Texas Express Pipelines
In May 2018, we conducted open commitment periods to determine shipper interest in expansions of the Front Range Pipeline (“Front Range”) and Texas Express Pipeline (“Texas Express”).  Given the positive responses we received from shippers, we will proceed with the proposed expansions.   We own a 33.3% equity interest in Front Range and a 35.0% equity interest in Texas Express.   We operate both pipelines.

The expansions are designed to facilitate growing production of NGLs from domestic shale basins, including the DJ Basin in Colorado, by providing DJ Basin producers with flow assurance and greater access to the Gulf Coast markets.  The expansions are expected to increase the transportation capacity of Front Range and Texas Express by 100 MBPD and 90 MBPD, respectively.  We anticipate the expansion projects will be placed into service during the third quarter of 2019.

Enterprise Expands Marine Terminal on the Houston Ship Channel
In April 2018, we acquired 65-acres of waterfront property on the Houston Ship Channel for approximately $85.2 million, all of which was recorded as land.  The purchase price consisted of $55.2 million in cash with the remaining balance funded through 1,223,242 newly-issued Enterprise common units.  The land is located immediately to the east of EHT and is expected to facilitate future expansion projects at the terminal.

Acquisition of Remaining 50% Ownership Interest in Delaware Processing
In March 2018, we acquired the remaining 50% member interest in our Delaware Basin Gas Processing LLC (“Delaware Processing”) joint venture for $150.6 million in cash, net of $3.9 million of cash held by the former joint venture.  Delaware Processing owns a cryogenic natural gas processing facility (our “Waha” gas plant) having a capacity of 150 MMcf/d.  The Waha plant is located in Reeves County, Texas and entered service in August 2016. The acquired business serves growing production of NGL-rich natural gas from the Delaware Basin in West Texas and southern New Mexico. For information regarding this acquisition, see Note 11 of the Notes to Unaudited Condensed Consolidated Financial Statements included under Part I, Item 1 of this quarterly report.

Enterprise to Expand Butane Isomerization Facility
In January 2018, we announced plans to expand our butane isomerization facility by up to 30 MBPD of incremental capacity.   This expansion is supported by new long-term agreements, including a 20-year, 35 MBPD fee-based, tolling arrangement, to provide butane isomerization, storage and pipeline services.

Fluctuations in our consolidated revenues and cost of sales amounts are explained in large part by changes in energy commodity prices.  Energy commodity prices fluctuate for a variety of reasons, including supply and demand imbalances and geopolitical tensions.  The weighted-average indicative market price for NGLs was $0.94 per gallon in the third quarter of 2018 versus $0.68 per gallon during the third quarter of 2017.  Likewise, the weighted-average indicative market price for NGLs was $0.84 per gallon during the nine months ended September 30, 2018 compared to $0.65 per gallon during the same period in 2017.

An increase in our consolidated marketing revenues due to higher energy commodity sales prices may not result in an increase in gross operating margin or cash available for distribution, since our consolidated cost of sales amounts would also be higher due to comparable increases in the purchase prices of the underlying energy commodities.  The same correlation would be true in the case of lower energy commodity sales prices and purchase costs.

We attempt to mitigate commodity price exposure through our hedging activities and the use of fee-based arrangements.  See Note 14 of the Notes to Unaudited Condensed Consolidated Financial Statements included under Part I, Item 1 of this quarterly report for information regarding our commodity hedging activities.

Consolidated Income Statement Highlights
The following information highlights significant changes in our comparative income statement amounts and the primary drivers of such changes.

Revenues
Third Quarter of 2018 Compared to Third Quarter of 2017.  Total revenues for the third quarter of 2018 increased $2.7 billion when compared to the third quarter of 2017 primarily due to a $2.34 billion increase in marketing revenues. Revenues from the marketing of NGLs increased $1.48 billion quarter-to-quarter primarily due to higher sales prices, which accounted for a $760.8 million increase, and higher sales volumes, which accounted for an additional $722.1 million increase. Revenues from the marketing of crude oil, petrochemicals and refined products increased a net $834.7 million quarter-to-quarter primarily due to higher sales prices, which accounted for a $1.4 billion increase, partially offset by a $570.0 million decrease due to lower sales volumes.

Revenues from midstream services for the third quarter of 2018 increased $361.3 million when compared to the third quarter of 2017.  As a result of adopting ASC 606 on January 1, 2018, we recognized $215.8 million of revenues during the third quarter of 2018 in connection with the receipt of non-cash consideration (in the form of equity NGLs) for providing natural gas processing services. Midstream service revenues from our pipeline assets increased $118.1 million quarter-to-quarter primarily due to strong demand for transportation services in Texas and on the Appalachia-to-Texas Express (“ATEX”) pipeline.

Nine Months Ended September 30, 2018 Compared to Nine Months Ended September 30, 2017.  Total revenues for the nine months ended September 30, 2018 increased $6.54 billion when compared to the nine months ended September 30, 2017 primarily due to a $5.63 billion increase in marketing revenues.  Revenues from the marketing of crude oil increased $3.17 billion period-to-period primarily due to higher sales volumes, which accounted for a $1.63 billion increase, and higher sales prices, which accounted for an additional $1.54 billion increase.  Revenues from the marketing of NGLs, petrochemicals and refined products increased a net $2.46 billion period-to-period primarily due to higher sales prices, which accounted for a $2.9 billion increase, partially offset by a $441.5 million decrease due to lower sales volumes.

Revenues from midstream services for the nine months ended September 30, 2018 increased $902.6 million when compared to the nine months ended September 30, 2017.  As a result of adopting ASC 606, we recognized $491.4 million in connection with the receipt of non-cash consideration for providing natural gas processing services during the nine months ended September 30, 2018.  Midstream service revenues from our pipeline assets increased $312.1 million period-to-period primarily due to strong demand for transportation services in Texas and on the ATEX Pipeline.

For additional information regarding our consolidated revenues, including the adoption of ASC 606, see Note 9 of the Notes to Unaudited Condensed Consolidated Financial Statements included under Part I, Item 1 of this quarterly report.


Operating costs and expenses
Third Quarter of 2018 Compared to Third Quarter of 2017.  Total operating costs and expenses for the third quarter of 2018 increased $1.92 billion when compared to the third quarter of 2017 primarily due to a $1.79 billion increase in cost of sales.  The cost of sales associated with our NGL marketing activities increased $1.54 billion quarter-to-quarter primarily due to higher sales volumes, which accounted for a $785.6 million increase, and higher purchase prices, which accounted for an additional $538.1 million increase. In addition, cost of sales attributable to our NGL marketing activities for the third quarter of 2018 includes $215.8 million resulting from the adoption of ASC 606 and attributable to the sale and delivery of equity NGL products to customers.  The cost of sales associated with our marketing of crude oil increased a net $225.7 million quarter-to-quarter primarily due to higher purchase prices, which accounted for a $494.0 million increase, partially offset by lower sales volumes, which accounted for a $268.3 million decrease.

Other operating costs and expenses for the third quarter of 2018 increased $98.3 million when compared to the third quarter of 2017 primarily due to higher maintenance, power and employee compensation costs. Depreciation, amortization and accretion expense increased $45.5 million quarter-to-quarter primarily due to assets we constructed and placed into service since the third quarter of 2017 (e.g., our Midland-to-ECHO Pipeline and propane dehydrogenation (“PDH”) facility).

Nine Months Ended September 30, 2018 Compared to Nine Months Ended September 30, 2017.  Total operating costs and expenses for the nine months ended September 30, 2018 increased $5.63 billion when compared to the nine months ended September 30, 2017 primarily due to a $5.25 billion increase in cost of sales.  The cost of sales associated with our marketing of crude oil increased $3.05 billion period-to-period primarily due to higher purchase prices, which accounted for a $1.54 billion increase, and higher sales volumes, which accounted for an additional $1.5 billion increase. The cost of sales associated with our NGL marketing activities increased $2.27 billion period-to-period primarily due to higher sales price, which accounted for a $4.31 billion increase, partially offset by lower sales volumes, which accounted for a $2.53 billion decrease. In addition, cost of sales attributable to our NGL marketing activities for 2018 includes $491.4 million resulting from the adoption of ASC 606 and attributable to the sale and delivery of equity NGL products to customers.

Other operating costs and expenses for the nine months ended September 30, 2018 increased $289.7 million when compared to the nine months ended September 30, 2017 primarily due to higher maintenance, power and employee compensation costs.  In addition, we recorded $33.9 million of expense in 2018 in connection with the earnings allocation arrangement with Western, which ended May 31, 2018, involving our Midland-to-ECHO crude oil pipeline.  Depreciation, amortization and accretion expense increased $109.7 million period-to-period primarily due to assets we constructed and placed into service since the third quarter of 2017.

General and administrative costs
General and administrative costs for the three and nine months ended September 30, 2018 increased $11.4 million and $19.7 million, respectively, when compared to the same periods in 2017 primarily due to higher employee compensation and legal costs.

Equity in income of unconsolidated affiliates
Equity income from our unconsolidated affiliates for the third quarter of 2018 decreased $1.4 million quarter-to-quarter primarily due to lower earnings from our investments in crude oil pipelines, which accounted for a combined $12.2 million decrease, partially offset by higher earnings from investments in NGL pipelines, which increased a combined $9.4 million.  Equity income from our unconsolidated affiliates for the nine months ended September 30, 2018 increased $34.8 million when compared to the same period in 2017 primarily due to an increase in earnings from our investments in NGL pipelines.

Operating income
Operating income for the three and nine months ended September 30, 2018 increased $764.1 million and $918.7 million, respectively, when compared to the same periods in 2017 due to the previously described quarter-to-quarter and period-to-period changes in revenues, operating costs and expenses, general and administrative costs and equity in income of unconsolidated affiliates.

Interest expense
Interest expense for the three and nine months ended September 30, 2018 increased $35.6 million and $67.2 million, respectively, when compared to the same periods in 2017.  The following table presents the components of our consolidated interest expense for the periods indicated (dollars in millions):

(1)   Amount presented for three and nine months ended September 30, 2018 includes $10.4 million and $29.4 million, respectively, of swaption premium income.
(2)   We capitalize interest costs incurred on funds used to construct property, plant and equipment while the asset is in its construction phase. Capitalized interest amounts become part of the historical cost of an asset and are charged to earnings (as a component of depreciation expense) on a straight-line basis over the estimated useful life of the asset once the asset enters its intended service. When capitalized interest is recorded, it reduces interest expense from what it would be otherwise. Capitalized interest amounts fluctuate based on the timing of when projects are placed into service, our capital spending levels and the interest rates charged on borrowings.
(3)   Primarily reflects facility commitment fees charged in connection with our revolving credit facilities and amortization and write-off of debt issuance costs. Amount presented for the three and nine months ended September 30, 2018 includes $6.4 million and $14.2 million, respectively, of debt issuance costs that were written off in connection with the redemption of junior subordinated notes.
  

Interest charged on debt principal outstanding, which is the primary driver of interest expense, increased a net $15.5 million quarter-to-quarter primarily due to increased debt principal amounts outstanding during the third quarter of 2018, which accounted for a $21.2 million increase, partially offset by the effect of lower overall interest rates during the third quarter of 2018, which accounted for a $5.7 million decrease.  Our weighted-average debt principal balance for the third quarter of 2018 was $26.08 billion compared to $24.20 billion for the third quarter of 2017.

For the nine months ended September 30, 2018, interest charged on debt principal outstanding increased a net $59.6 million period-to-period primarily due to increased debt principal amounts outstanding during the nine months ended September 30, 2018, which accounted for a $67.3 million increase, partially offset by the effect of lower overall interest rates during the nine months ended September 30, 2018, which accounted for a $7.7 million decrease.  Our weighted-average debt principal balance for the nine months ended September 30, 2018 was $25.76 billion compared to $23.87 billion for the nine months ended September 30, 2017.

Our debt principal balances have increased over time due to the partial debt financing of our capital spending program.  For a discussion of our consolidated debt obligations and capital spending program, see “Liquidity and Capital Resources” and “Capital Spending” within this Part I, Item 2.

Change in fair value of Liquidity Option Agreement
The change in fair value of the Liquidity Option Agreement reflects non-cash expense attributable to accretion and changes in management estimates regarding inputs to the valuation model.  For the three and nine months ended September 30, 2018, expense resulting from changes in fair value of the Liquidity Option Agreement increased $9.6 million and $1.9 million, respectively, when compared to the same periods in 2017.   For information regarding the Liquidity Option Agreement, see Note 16 of the Notes to Unaudited Condensed Consolidated Financial Statements included under Part I, Item 1 of this quarterly report.

Gain on step acquisition of unconsolidated affiliate
We recognized a gain of $39.4 million during the nine months ended September 30, 2018 related to the step acquisition of Delaware Processing.  For information regarding this acquisition, see Note 11 of the Notes to Unaudited Condensed Consolidated Financial Statements included under Part I, Item 1 of this quarterly report.


Income taxes
Income taxes primarily reflect our state tax obligations under the Revised Texas Franchise Tax.  Our provision for income taxes for the three and nine months ended September 30, 2018 increased $5.6 million and $14.4 million, respectively, when compared to the same periods in 2017.
 
Business Segment Highlights

The following information highlights significant changes in our quarter-to-quarter and period-to-period segment results (i.e., our gross operating margin by segment amounts) and the primary drivers of such changes. The volume statistics presented for each segment are reported on a net basis, taking into account our ownership interests, and reflect the periods in which we owned an interest in such operations.

Total Gross Operating Margin
We evaluate segment performance based on our financial measure of gross operating margin.  Gross operating margin is an important performance measure of the core profitability of our operations and forms the basis of our internal financial reporting.  We believe that investors benefit from having access to the same financial measures that our management uses in evaluating segment results.

(1)   Within the context of this table, total segment gross operating margin represents a subtotal and corresponds to measures similarly titled within our business segment disclosures found in Note 10 of the Notes to Unaudited Condensed Consolidated Financial Statements included under Part I, Item 1 of this quarterly report.
  

Total gross operating margin includes equity in the earnings of unconsolidated affiliates, but is exclusive of other income and expense transactions, income taxes, the cumulative effect of changes in accounting principles and extraordinary charges.  Total gross operating margin is presented on a 100% basis before any allocation of earnings to noncontrolling interests.

Gross operating margin by segment for NGL Pipelines & Services and Crude Oil Pipelines & Services reflect adjustments for shipper make-up rights that are included in management’s evaluation of segment results.  However, these adjustments are excluded from non-GAAP total gross operating margin.
 
In late August and early September 2017, the Gulf Coast region of Texas, including its critical energy infrastructure, was impacted by the cumulative effects of Hurricane Harvey.  Impacts on the energy industry included, but were not limited to, severe flooding and limited access to facilities, disruptions to energy demand from area refineries and petrochemical facilities and the closure of all ports on the Texas Gulf Coast, which limited access to export markets.  Although operating at reduced rates, many of our plant, pipeline and storage assets along the Texas Gulf Coast remained operational during the storm.  We estimate that Hurricane Harvey reduced our gross operating margin for the third quarter of 2017 by approximately $35 million, of which $25 million was attributable to our Petrochemical & Refined Products Services business segment and $7 million to our NGL Pipelines & Services business segment.

 

The GAAP financial measure most directly comparable to total gross operating margin is operating income.  For a discussion of operating income and its components, see the previous section titled “Consolidated Income Statement Highlights” within this Part I, Item 2.  The following table presents a reconciliation of operating income to total gross operating margin for the periods indicated (dollars in millions):

Each of our business segments benefits from the supporting role of our marketing activities.  The main purpose of our marketing activities is to support the utilization and expansion of assets across our midstream energy asset network by increasing the volumes handled by such assets, which results in additional fee-based earnings for each business segment.  In performing these support roles, our marketing activities also seek to participate in supply and demand opportunities as a supplemental source of gross operating margin for the partnership.  The financial results of our marketing efforts fluctuate due to changes in volumes handled and overall market conditions, which are influenced by current and forward market prices for the products bought and sold.

Natural gas processing and related NGL marketing activities
Third Quarter of 2018 Compared to Third Quarter of 2017. Gross operating margin from natural gas processing and related NGL marketing activities for the third quarter of 2018 increased $193.6 million when compared to the third quarter of 2017.

Gross operating margin from our NGL marketing activities increased $86.9 million quarter-to-quarter primarily due to higher average sales margins.  The results from marketing strategies that optimize our transportation and plant assets increased a combined $92.7 million quarter-to-quarter primarily due to higher basis spreads during the third quarter of 2018, partially offset by an $8.0 million decrease in earnings from export-related strategies.

Results from our NGL marketing strategies for the third quarter of 2018 benefited from strong commodity prices and wide basis spreads resulting from constrained takeaway pipeline capacity due to increased production from major producing areas such as the Permian Basin and Midcontinent regions and tightness in downstream NGL fractionation capacity.  Ethane demand from ethylene crackers is currently at peak levels of 1.5 MMBPD (a 37% increase versus one year ago) as several new large ethylene plants along the U.S. Gulf Coast have commenced operations during 2018. From a pricing perspective, average ethane prices increased 48% quarter-to-quarter from $0.29 per gallon in the second quarter of 2018 to $0.43 per gallon in the third quarter of 2018, with daily highs of approximately $0.60 per gallon in late September 2018.  Based on current trends, we expect basis differentials and overall commodity prices to be lower in the fourth quarter of 2018.

Gross operating margin from our Meeker, Pioneer and Chaco natural gas processing plants increased a net $58.7 million quarter-to-quarter primarily due to higher average processing margins (including the impact of hedging activities), which accounted for an increase of $87.3 million, partially offset by the effects of lower equity NGL production volumes of 19 MBPD, which accounted for a $31.0 million decrease.  On a combined basis for these plants, fee-based natural gas processing volumes increased 164 MMcf/d quarter-to-quarter.  Likewise, gross operating margin from our South Texas natural gas processing plants increased a net $18.4 million quarter-to-quarter primarily due to higher average processing margins (including the impact of hedging activities), which accounted for a $40.2 million increase, partially offset by lower equity NGL production volumes of 25 MBPD, which accounted for a $23.5 million decrease.  Fee-based natural gas processing volumes at our South Texas plants decreased 103 MMcf/d quarter-to-quarter. We elected to reduce our overall equity NGL production volumes during the third quarter of 2018 to help alleviate takeaway pipeline capacity constraints, which allowed us to optimize our midstream asset network.

Gross operating margin from our Permian Basin natural gas processing plants (South Eddy, Orla and Waha) increased a net $19.4 million quarter-to-quarter.  Our Orla gas plant, which commenced commercial operations during the second quarter of 2018, contributed gross operating margin of $11.3 million and fee-based natural gas processing volumes of 198 MMcf/d for the quarter.  Gross operating margin from our Waha gas plant increased $10.8 million quarter-to-quarter and fee-based natural gas processing volumes increased 111 MMcf/d quarter-to-quarter primarily due to our acquisition of the remaining 50% equity interest in the Delaware Basin joint venture in March 2018.  Gross operating margin from our South Eddy gas plant decreased $2.7 million quarter-to-quarter primarily due to lower natural gas processing volumes of 62 MMcf/d.

Gross operating margin from our natural gas processing plants in Louisiana and Mississippi increased $10.1 million quarter-to-quarter primarily due to higher equity NGL production volumes of 15 MBPD, which accounted for a $7.5 million increase, and higher average processing margins, which accounted for an additional $3.6 million increase.   Fee-based natural gas processing volumes for these plants decreased 21 MMcf/d quarter-to-quarter.

Nine Months Ended September 30, 2018 Compared to Nine Months Ended September 30, 2017.  Gross operating margin from natural gas processing and related NGL marketing activities for the nine months ended September 30, 2018 increased $269.2 million when compared to the nine months ended September 30, 2017.

Midland-to-ECHO Pipeline and related business activities
Gross operating margin from our Midland-to-ECHO Pipeline and related business activities was a combined $281.5 million for the third quarter of 2018 and $5.4 million for the nine months ended September 30, 2018. Transportation volumes for the Midland-to-ECHO Pipeline, which entered limited service in November 2017 and full service in April 2018, averaged 453 MBPD and 429 MBPD during the three and nine months ended September 30, 2018, respectively (net to our interest).

Gross operating margin for this business for the three and nine months ended September 30, 2018 reflects a non-cash mark-to-market gain of $186.7 million and loss of $237.3 million, respectively, associated with the hedging of crude oil commodity price differentials (basis spreads) between the Midland and Houston area markets.  These hedges, which were primarily entered into throughout 2017, serve to lock in a positive margin on our anticipated purchases of crude oil at Midland and subsequent anticipated sales to customers in the Houston area for periods extending predominantly into 2019 and minimally through 2020. At September 30, 2018, these hedges represented a weighted average of approximately 32% of the pipeline’s expected uncommitted capacity through 2020 at an average positive margin of $2.66 per barrel. The year-to-date mark-to-market loss of $237.3 million reflects a widening of the basis spread between the Midland and Houston markets to an average of $13.13 per barrel through 2020 relative to our average hedged amount of $2.66 per barrel across these same periods as of September 30, 2018. The mark-to-market gain recognized for the third quarter of 2018 reflects the reversal of previously recognized mark-to-market losses for these hedges upon cash settlement of the underlying instruments as well as a narrowing of the basis spreads between the Midland and Houston markets during the quarter.

Basis swaps, in all but very limited circumstances, do not qualify for cash flow hedge accounting despite being highly effective at hedging the price risk inherent in the underlying physical transactions.  The volume hedged through 2020 varies from quarter-to-quarter and year-to-year, however the hedge levels generally correspond to pipeline capacity currently expected to be available to us during the first three years of the pipeline’s operations as customer commitment volumes ramp up to peak levels.

If the basis spreads underlying these hedges widen from the levels at September 30, 2018, we would be exposed to additional temporary non-cash mark-to-market losses.  Conversely, if basis spreads narrow in the future reverting back towards or below the average $2.66 per barrel spread we have locked in at September 30, 2018, then we would recognize temporary non-cash mark-to-market gains in future periods.  When the forecasted physical receipts and deliveries of crude oil ultimately occur in the future, we will realize a physical gross margin at then prevailing commodity price spreads; however the realized settlement of the associated financial hedges would convert that physical margin to the average $2.66 per barrel spread of the financial hedges.  At that time, the unrealized mark-to-market loss recognized for the nine months ended September 30, 2018 and in future periods until the physical deliveries occur will be reversed, thus eliminating their impact to cumulative earnings recognized over the entire life-to-date period of the hedge.

The basis spread between the Midland and Houston markets continues to fluctuate.  We also have uncommitted capacity on the pipeline that could provide us with potential upside to widening or downside to narrowing market spreads.  For information regarding the impact of these spreads on our crude oil marketing hedging portfolio, see Part I, Item 3, Quantitative and Qualitative Disclosures about Market Risk.  For general information regarding our derivative instruments and hedging activities, see Note 14 of the Notes to Unaudited Condensed Consolidated Financial Statements included under Part I, Item 1 of this quarterly report.

Gross operating margin from the Midland-to-ECHO Pipeline for the nine months ended September 30, 2018 was also reduced by $33.9 million in connection with the allocation of pipeline earnings to Western upon closing of their acquisition of a noncontrolling 20% equity interest in the pipeline on June 1, 2018.  For additional information regarding this transaction, see “Significant Recent Developments” within this Part I, Item 2.

Nine Months Ended September 30, 2018 Compared to Nine Months Ended September 30, 2017.  Gross operating margin from butane isomerization and DIB operations for the nine months ended September 30, 2018 increased $30.5 million when compared to the nine months ended September 30, 2017. The increase in gross operating margin period-to-period is primarily due to higher average by-product sales prices, which accounted for a $16.5 million increase, higher production and sales volumes, which accounted for an $8.7 million increase, and higher DIB processing fees, which accounted for an additional $4.5 million increase.

Octane enhancement and related operations
Third Quarter of 2018 Compared to Third Quarter of 2017.  Gross operating margin from our octane enhancement facility and high purity isobutylene plant for the third quarter of 2018 increased a combined $5.2 million when compared to the third quarter of 2017 primarily due to higher sales volumes, which accounted for a $6.9 million increase, partially offset by higher maintenance and other operating costs, which accounted for a $2.5 million decrease.

Nine Months Ended September 30, 2018 Compared to Nine Months Ended September 30, 2017.  Gross operating margin from our octane enhancement facility and high purity isobutylene plant for the nine months ended September 30, 2018 increased a combined $29.6 million when compared to the nine months ended September 30, 2017 primarily due to higher sales volumes.

Refined products pipelines and related activities
Third Quarter of 2018 Compared to Third Quarter of 2017.  Gross operating margin from refined products pipelines and related marketing activities for the third quarter of 2018 increased $10.5 million when compared to the third quarter of 2017.  Gross operating margin from our TE Products Pipeline and related refined products terminals increased $10.4 million quarter-to-quarter primarily due to higher average transportation and other fees, which accounted for a $7.5 million increase, and higher NGL transportation volumes, which accounted for an additional $5.7 million increase.  NGL and refined product transportation volumes on our TE Products Pipeline increased a combined 18 MBPD, while petrochemical transportation volumes decreased 12 MBPD quarter-to-quarter.

Nine Months Ended September 30, 2018 Compared to Nine Months Ended September 30, 2017.  Gross operating margin from refined products pipelines and related marketing activities for the nine months ended September 30, 2018 increased $17.3 million when compared to the nine months ended September 30, 2017.

Gross operating margin from our TE Products Pipeline and related refined products terminals increased a net $23.4 million period-to-period primarily due to higher average transportation and other fees, which accounted for a $21.0 increase, and higher NGL transportation volumes, which accounted for an additional $17.6 million increase, partially offset by higher maintenance and other operating costs, which accounted for a $15.2 million decrease.  NGL transportation volumes on our TE Products Pipeline increased 16 MBPD, while refined product and petrochemical transportation volumes decreased a combined 33 MBPD period-to-period.

Gross operating margin from our Houston Ship Channel and Beaumont refined products marine terminals decreased a combined $8.9 million period-to-period primarily due to lower storage revenues.

Marine transportation and other
Third Quarter of 2018 Compared to Third Quarter of 2017.  Gross operating margin from marine transportation for the third quarter of 2018 increased $2.7 million when compared to the third quarter of 2017 primarily due to higher marine vessel utilization.

Nine Months Ended September 30, 2018 Compared to Nine Months Ended September 30, 2017.  Gross operating margin from marine transportation and other services for the nine months ended September 30, 2018 increased $8.0 million when compared to the nine months ended September 30, 2017 primarily due to higher marine vessel utilization period-to-period, which accounted for a $4.1 million increase, and lower costs, which accounted for an additional $4.0 million increase.

Liquidity and Capital Resources

Based on current market conditions (as of the filing date of this quarterly report), we believe we will have sufficient liquidity, cash flow from operations and access to capital markets to fund our capital expenditures and working capital needs for the reasonably foreseeable future.  At September 30, 2018, we had $3.32 billion of consolidated liquidity, which was comprised of $3.29 billion of available borrowing capacity under EPO’s revolving credit facilities and $30.2 million of unrestricted cash on hand.

We may issue additional equity and debt securities to assist us in meeting our future funding and liquidity requirements, including those related to capital spending.

Issuance of $3.0 Billion of Senior Notes in October 2018
In October 2018, EPO issued $3.0 billion aggregate principal amount of senior notes comprised of (i) $750 million principal amount of senior notes due February 2022 (“Senior Notes VV”), (ii) $1.0 billion principal amount of senior notes due October 2028 (“Senior Notes WW”) and (iii) $1.25 billion principal amount of senior notes due February 2049 (“Senior Notes XX”).  Net proceeds from this offering were used by EPO for the temporary repayment of amounts outstanding under its commercial paper program and general company purposes, including for growth capital expenditures.

Senior Notes VV were issued at 99.985% of their principal amount and have a fixed-rate interest rate of 3.50% per year.  Senior Notes WW were issued at 99.764% of their principal amount and have a fixed-rate interest rate of 4.15% per year.  Senior Notes XX were issued at 99.390% of their principal amount and have a fixed-rate interest rate of 4.80% per year.  Enterprise Products Partners L.P. has guaranteed the senior notes through an unconditional guarantee on an unsecured and unsubordinated basis.

Issuance of $2.0 Billion of Senior Notes and $700 Million of Junior Subordinated Notes in February 2018
In February 2018, EPO issued $2.7 billion aggregate principal amount of notes comprised of (i) $750 million principal amount of senior notes due February 2021 (“Senior Notes TT”), (ii) $1.25 billion principal amount of senior notes due February 2048 (“Senior Notes UU”) and (iii) $700 million principal amount of junior subordinated notes due February  2078 (“Junior Subordinated Notes F”).  Net proceeds from these offerings were used by EPO for the temporary repayment of amounts outstanding under its commercial paper program, general company purposes, and the redemption of all $682.7 million outstanding aggregate principal amount of its Junior Subordinated Notes B.

Senior Notes TT were issued at 99.946% of their principal amount and have a fixed-rate interest rate of 2.80% per year.  Senior Notes UU were issued at 99.865% of their principal amount and have a fixed-rate interest rate of 4.25% per year.  Enterprise Products Partners L.P. has guaranteed the senior notes through an unconditional guarantee on an unsecured and unsubordinated basis.

The Junior Subordinated Notes F are redeemable at EPO’s option, in whole or in part, on one or more occasions, on or after February 15, 2028 at 100% of their principal amount, plus any accrued and unpaid interest thereon, and bear interest at a fixed rate of 5.375% per year through February 14, 2028.  Beginning February 15, 2028, the Junior Subordinated Notes F will bear interest at a floating rate based on a three-month LIBOR plus 2.57%, reset quarterly.  Enterprise Products Partners L.P. has guaranteed the Junior Subordinated Notes F through an unconditional guarantee on an unsecured and subordinated basis.

Redemption of Junior Subordinated Notes
In March 2018, EPO redeemed all of the $682.7 million outstanding aggregate principal amount of its Junior Subordinated Notes B at a price equal to 100% of the principal amount of the notes being redeemed, plus all accrued and unpaid interest thereon to, but not including, the redemption date.  This redemption was funded by EPO’s issuance of senior notes and junior subordinated notes in February 2018.

In August 2018, EPO redeemed all of the $521.1 million outstanding aggregate principal amount of its Junior Subordinated Notes A at a price equal to 100% of the principal amount of the notes being redeemed, plus all accrued and unpaid interest thereon to, but not including, the redemption date.  This redemption was funded by the issuance of short-term notes under EPO’s commercial paper program.

364-Day Revolving Credit Agreement
In September 2018, EPO entered into a 364-Day Revolving Credit Agreement that replaced its prior 364-day credit facility.  The new 364-Day Revolving Credit Agreement matures in September 2019. There are currently no principal amounts outstanding under this revolving credit agreement.

Under the terms of the new 364-Day Revolving Credit Agreement, EPO may borrow up to $2.0 billion (which may be increased by up to $200 million to $2.2 billion at EPO’s election, provided certain conditions are met) at a variable interest rate for a term of up to 364 days, subject to the terms and conditions set forth therein.  To the extent that principal amounts are outstanding at the maturity date, EPO may elect to have the entire principal balance then outstanding continued as a non-revolving term loan for a period of one additional year, payable in September 2020. Borrowings under this revolving credit agreement may be used for working capital, capital expenditures, acquisitions and general company purposes.

The new 364-Day Revolving Credit Agreement contains customary representations, warranties, covenants (affirmative and negative) and events of default, the occurrence of which would permit the lenders to accelerate the maturity date of any amounts borrowed under this credit agreement.  The credit agreement also restricts EPO’s ability to pay cash distributions to its parent, Enterprise Products Partners L.P., if an event of default (as defined in the credit agreement) has occurred and is continuing at the time such distribution is scheduled to be paid or would result therefrom.

EPO’s obligations under the new 364-Day Revolving Credit Agreement are not secured by any collateral; however, they are guaranteed by Enterprise Products Partners L.P.

Increase in Amount Authorized under Commercial Paper Program
In June 2018, EPO increased the aggregate principal amount of short-term notes that it could issue (and have outstanding at any time) under its commercial paper program from $2.5 billion to $3.0 billion.  The commercial paper program enables us to access typically lower short-term interest rates, which allows us to manage working capital and our overall cost of capital. As a back-stop to the commercial paper program, we intend to maintain a minimum available borrowing capacity under EPO’s Multi-Year Revolving Credit Facility equal to the outstanding aggregate principal amount of EPO’s commercial paper notes.  All commercial paper notes issued under the program are senior unsecured obligations of EPO that are unconditionally guaranteed by Enterprise Products Partners L.P.

For additional information regarding our debt agreements, see Note 7 of the Notes to Unaudited Condensed Consolidated Financial Statements included under Part I, Item 1 of this quarterly report.

Credit Ratings

At November 1, 2018, the investment-grade credit ratings of EPO’s long-term senior unsecured debt securities were BBB+ from Standard and Poor’s, Baa1 from Moody’s and BBB+ from Fitch Ratings.  In addition, the credit ratings of EPO’s short-term senior unsecured debt securities were A-2 from Standard and Poor’s, P-2 from Moody’s and F-2 from Fitch Ratings.

EPO’s credit ratings reflect only the view of a rating agency and should not be interpreted as a recommendation to buy, sell or hold any of our securities.  A credit rating can be revised upward or downward or withdrawn at any time by a rating agency, if it determines that circumstances warrant such a change.  A credit rating from one rating agency should be evaluated independently of credit ratings from other rating agencies.

Issuance of Common Units

DRIP and EUPP
We have a registration statement on file with the SEC in connection with our 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 our common units they own by reinvesting the quarterly cash distributions they receive from us into the purchase of additional new common units.  After taking into account the number of common units issued under the DRIP through September 30, 2018, we have the capacity to issue an additional 64,643,166 common units under this plan.

Pursuant to the DRIP, privately held affiliates of EPCO purchased $100 million of our common units in connection with the distribution paid in February 2018 and an additional $106 million of our common units in connection with the distribution paid on August 8, 2018.

In addition to the DRIP, we have registration statements on file with the SEC in connection with our EUPP.  After taking into account the number of common units issued under the EUPP through September 30, 2018, we have the capacity to issue an additional 5,357,209 common units under this plan.

ATM Program
We have a registration statement on file with the SEC covering the issuance of up to $2.54 billion of our common units in amounts, at prices and on terms to be determined by market conditions and other factors at the time of such offerings in connection with our at-the-market (“ATM”) program.  No sales were made under this program during the nine months ended September 30, 2018.  After taking into account the aggregate sales price of common units sold under the ATM program in periods prior to fiscal 2018, we have the capacity to issue additional common units under the ATM program up to an aggregate sales price of $2.54 billion.

Use of Proceeds
The net cash proceeds we received from the issuance of common units during the nine months ended September 30, 2018 were used to temporarily reduce amounts outstanding under EPO’s commercial paper program and for general company purposes.

For additional information regarding our issuance of common units and related registration statements, see Note 8 of the Notes to Unaudited Condensed Consolidated Financial Statements included under Part I, Item 1 of this quarterly report.

Restricted Cash

Restricted cash represents amounts held in segregated bank accounts by our clearing brokers as margin in support of our commodity derivative instruments portfolio and related physical purchases and sales of natural gas, NGLs, crude oil and refined products.  At September 30, 2018 and December 31, 2017, our restricted cash amounts were $248.9 million and $65.2 million, respectively.

Additional cash may be restricted to maintain our commodity derivative instruments portfolio as prices fluctuate or margin requirements change.  For information regarding our derivative instruments and hedging activities, see Note 14 of the Notes to Unaudited Condensed Consolidated Financial Statements included under Part I, Item 1 of this quarterly report.  In addition, see Part I, Item 3, Quantitative and Qualitative Disclosures about Market Risk.
 
Cash Flows from Operating, Investing and Financing Activities

The following table summarizes our consolidated cash flows from operating, investing and financing activities for the periods indicated (dollars in millions).  For additional information regarding our cash flow amounts, please refer to the Unaudited Condensed Statements of Consolidated Cash Flows included under Part I, Item 1 of this quarterly report.

Net cash flows provided by operating activities are largely dependent on earnings from our consolidated business activities.  We operate in the midstream energy industry, which includes gathering, transporting, processing, fractionating and storing natural gas, NGLs, crude oil, petrochemical and refined products.  As such, changes in the prices of hydrocarbon products and in the relative price levels among hydrocarbon products could have a material adverse effect on our financial position, results of operations and cash flows.  Changes in prices may impact demand for hydrocarbon products, which in turn may impact production, demand and the volumes of products for which we provide services.  In addition, decreases in demand may be caused by other factors, including prevailing economic conditions, reduced demand by consumers for the end products made with hydrocarbon products, increased competition, adverse weather conditions and government regulations affecting prices and production levels.  We may also incur credit and price risk to the extent customers do not fulfill their obligations to us in connection with our marketing of natural gas, NGLs, propylene, refined products and/or crude oil and long-term take-or-pay agreements.  For a more complete discussion of these and other risk factors pertinent to our business, see “Risk Factors” under Part I, Item 1A of our 2017 Form 10-K.

Comparison of Nine Months Ended September 30, 2018 with Nine Months Ended September 30, 2017
The following information highlights significant period-to-period fluctuations in our consolidated cash flow amounts:

Operating activities.  Net cash flows provided by operating activities for the nine months ended September 30, 2018 increased $1.46 billion when compared to the same period in 2017.  The increase in cash provided by operating activities was primarily due to:

§
a $1.18 billion increase in cash resulting from higher partnership earnings in the nine months ended September 30, 2018 compared to the same period in 2017 (after adjusting our $875.0 million period-to-period increase in net income for changes in the non-cash items identified on our Unaudited Condensed Statements of Consolidated Cash Flows);

§
a $250.2 million period-to-period increase in cash primarily due to the timing of cash receipts and payments related to operations; and

§
a $29.5 million period-to-period increase in cash distributions received on earnings from unconsolidated affiliates primarily due to our investments in NGL pipeline joint ventures.

For information regarding significant period-to-period changes in our consolidated net income and underlying segment results, see “Results of Operations” within this Part I, Item 2.

Investing activities.  Cash used for investing activities in the nine months ended September 30, 2018 increased $878.9 million when compared to the same period in 2017 primarily due to:

§
an $886.0 million period-to-period increase in spending for consolidated property, plant and equipment (see “Capital Spending” within this Part I, Item 2 for additional information regarding our capital spending program); and

§
a $62.3 million period-to-period increase in investments in unconsolidated affiliates primarily related to our NGL pipeline and crude oil joint ventures; partially offset by

§
a $48.1 million period-to-period decrease in net cash used for business combinations.  During the nine months ended September 30, 2018, we used $150.6 million to acquire the remaining 50% equity interest in Delaware Processing.   For the same period in 2017, we used $191.4 million to acquire the BTA Gathering System and related assets.

Financing activities.  Cash used in financing activities for the nine months ended September 30, 2018 increased $49.8 million when compared to the same period in 2017 primarily due to:

§
a $427.8 million period-to-period decrease in net cash proceeds from the issuance of common units.  We issued an aggregate 16,477,576 common units, which generated $449.4 million of net cash proceeds, in connection with our DRIP and EUPP during the nine months ended September 30, 2018.  This compares to an aggregate 32,518,315 common units we issued in connection with our ATM, DRIP and EUPP during the nine months ended September 30, 2017, which collectively generated $877.2 million of net cash proceeds; and

§
a $122.5 million period-to-period increase in cash distributions paid to limited partners during the nine months ended September 30, 2018 when compared to the nine months ended September 30, 2017.  The increase in cash distributions is due to increases in both the number of distribution-bearing common units outstanding and the quarterly cash distribution rates per unit; partially offset by

§
a net $327.0 million increase in net cash inflows attributable to debt issuances, which was comprised of an $832.9 million increase in net issuances of short-term notes under EPO’s commercial paper program, partially offset by a  $505.9 million period-to-period decrease in net cash inflows due to the issuance of $2.7 billion in principal amount of senior and junior subordinated notes offset by the repayment or redemption of $2.3 billion in principal amount of senior and junior subordinated notes during the nine months ended September 30, 2018 compared to the issuance of $1.7 billion in principal amount of junior subordinated notes and repayment of $800.0 million in principal amount of senior notes during the nine months ended September 30, 2017; and

§
a $221.6 million period-to-period increase in contributions from noncontrolling interests. In June 2018, an affiliate of Western acquired a noncontrolling 20% equity interest in our consolidated subsidiary that owns the Midland-to-ECHO Pipeline for $189.6 million in cash.

Sale of Red River System in October 2018
 
On October 1, 2018, we closed on the sale of our Red River System and associated crude oil linefill for approximately $135 million, of which $10.5 million was received as a deposit in the third quarter of 2018.   The Red River System gathers and transports crude oil from North Texas and southern Oklahoma for delivery to local refineries and pipeline interconnects for further transportation to the Cushing hub and Gulf Coast.   As of September 30, 2018, the carrying value of these assets totaled $109.6 million, which was classified as held-for-sale primarily within other current assets on our Unaudited Consolidated Balance Sheet.

Cash Distributions to Limited Partners

Our partnership agreement requires us to make quarterly distributions to our unitholders of all available cash, after any cash reserves established by Enterprise GP in its sole discretion.  Cash reserves include those for the proper conduct of our business including, for example, those for capital expenditures, debt service, working capital, operating expenses, commitments and contingencies and other significant amounts.  The retention of cash by the partnership allows us to reinvest in our growth and reduce our future reliance on the equity and debt capital markets.  

We measure available cash by reference to “distributable cash flow,” which is a non-GAAP liquidity measure.  Distributable cash flow is an important non-GAAP financial measure for our limited partners since it serves as an indicator of our success in providing a cash return on investment.  Specifically, this financial measure indicates to investors whether or not we are generating cash flows at a level that can sustain or support an increase in our quarterly cash distributions.  Distributable cash flow is also a quantitative standard used by the investment community with respect to publicly traded partnerships because the value of a partnership unit is, in part, measured by its yield, which is based on the amount of cash distributions a partnership can pay to a unitholder.  Our management compares the distributable cash flow we generate to the cash distributions we expect to pay our partners.  Using this metric, management computes our distribution coverage ratio.  


Based on the level of available cash, management proposes a quarterly cash distribution rate to the Board of Enterprise GP, which has sole authority in approving such matters.  Unlike several other master limited partnerships, our general partner has a non-economic ownership interest in us and is not entitled to receive any cash distributions from us based on incentive distribution rights or other equity interests.

Our use of distributable cash flow for the limited purposes described above and in this report is not a substitute for net cash flows provided by operating activities, which is the most comparable GAAP measure. For a discussion of net cash flows provided by operating activities, see the previous section titled “Cash Flows from Operating, Investing and Financing Activities” within this Part I, Item 2.

Capital Spending

We currently have approximately $6.0 billion of growth capital projects scheduled to be completed by mid-2020 including:

§
joint venture-owned dock infrastructure in Corpus Christi designed to accommodate crude oil volumes (first quarter of 2019);

§
the Shin Oak NGL Pipeline (second quarter of 2019);

§
the third processing train at our Orla natural gas processing facility (second quarter of 2019);

§
expansions of our Front Range and Texas Express NGL pipelines (third quarter of 2019);

§
our isobutane dehydrogenation (“iBDH”) unit (fourth quarter of 2019);

§
our ethylene export terminal (fourth quarter of 2019);

§
a new NGL fractionation facility at Mont Belvieu (first half of 2020);

§
our Mentone cryogenic natural gas processing plant (first quarter of 2020); and

§
a 150 MBPD expansion of NGL fractionation capacity at our Mont Belvieu complex (second quarter of 2020).

Based on information currently available, we expect our total growth capital spending for 2018 to approximate $4.2 billion, which includes the $150.6 million we invested to acquire the remaining 50% equity interest in Delaware Processing.  We expect our sustaining capital expenditures for 2018 to approximate $315 million, of which $221.5 million was spent in the nine months ended September 30, 2018.

Our forecast of capital spending for 2018 is based on our announced strategic operating and growth plans (through the filing date of this quarterly report), which are dependent upon our ability to generate the required funds from either operating cash flows or other means, including borrowings under debt agreements, the issuance of additional equity and debt securities, and potential divestitures.  We may revise our forecast of capital spending due to factors beyond our control, such as adverse economic conditions, weather related issues and changes in supplier prices.  Furthermore, our forecast of capital spending may change as a result of decisions made by management at a later date, which may include unforeseen acquisition opportunities.

Our success in raising capital, including the formation of joint ventures to share costs and risks, continues to be a significant factor in determining how much capital we can invest.  We believe our access to capital resources is sufficient to meet the demands of our current and future growth needs and, although we expect to make the forecast capital expenditures noted above, we may adjust the timing and amounts of projected expenditures in response to changes in capital market conditions.

The following table summarizes the primary elements of our capital spending for the periods indicated (dollars in millions):

(1)   Growth and sustaining capital amounts presented in the table above are presented on a cash basis.
(2)   Growth capital projects either (a) result in new sources of cash flow due to enhancements of or additions to existing assets (e.g., additional revenue streams, cost savings resulting from debottlenecking of a facility, etc.) or (b) expand our asset base through construction of new facilities that will generate additional revenue streams and cash flows.
(3)   Sustaining capital expenditures are capital expenditures (as defined by GAAP) resulting from improvements to existing assets. Such expenditures serve to maintain existing operations but do not generate additional revenues or result in significant cost savings.
(4)   Amount presented for the nine months ended September 30, 2018 represents the acquisition of the remaining 50% ownership interest in our Delaware Processing joint venture, which closed on March 29, 2018.
  

Fluctuations in our spending for growth capital projects and investments in unconsolidated affiliates are explained in large part by increases or decreases in spending on major expansion projects.  Our most significant growth capital expenditures for the nine months ended September 30, 2018 involved projects to support crude oil, natural gas and NGL production from the Permian Basin, export activities at our Gulf Coast terminal and spending on our iBDH unit.  Fluctuations in spending for sustaining capital projects are explained in large part by the timing and cost of pipeline integrity and similar projects.

Comparison of Nine Months Ended September 30, 2018 with Nine Months Ended September 30, 2017
Total capital spending increased a net $900.2 million period-to-period primarily due to the following:

§
Growth capital spending for projects to support Permian Basin production increased $585.6 million period-to-period.  We are in various stages of completion on multiple projects to support crude oil, natural gas and NGL production in the Permian Basin, including our Orla natural gas processing facility and related pipelines and the Shin Oak NGL Pipeline.

§
Growth capital spending on our iBDH unit increased $241.8 million period-to-period.

§
Growth capital spending for projects to expand and support export activities at EHT increased $210.3 million period-to-period.  This amount includes $55.2 million of cash paid in April 2018 to acquire a 65-acre waterfront site located on the Houston Ship Channel that will serve as the next phase of expansion at EHT.

§
Growth capital spending to expand refined products capabilities at our Beaumont terminal increased $68.6 million period-to-period.

§
Investments in unconsolidated affiliates increased $62.3 million period-to-period primarily due to spending on our Front Range and Texas Express expansion projects, which accounted for $33.7 million of the increase, and our joint venture dock infrastructure at Corpus Christi, which accounted for an additional $15.3 million increase.

§
Growth capital spending at our Mont Belvieu complex for the PDH facility and ninth NGL fractionator decreased $314.3 million period-to-period.

§
Net cash used for business combinations decreased $48.1 million period-to-period.  During the nine months ended September 30, 2018, we invested $150.6 million to acquire the remaining 50% equity interest in Delaware Processing.  For the same period in 2017, we used $191.4 million to acquire the BTA Gathering System and related assets.

 
Pipeline Integrity Program

Our pipelines operate under safety regulations administered by the U.S. Department of Transportation (“DOT”) that require pipeline integrity management programs for hazardous liquid and natural gas pipelines.  In general, these regulations require companies to assess the condition of their pipelines in certain high consequence areas (as defined by the regulation) and to perform any necessary repairs.

The following table summarizes our pipeline integrity costs, including those attributable to DOT regulations, for the periods presented (dollars in millions):

Critical Accounting Policies and Estimates

A discussion of our critical accounting policies and estimates is included in our 2017 Form 10-K.  The following types of estimates, in our opinion, are subjective in nature, require the exercise of professional judgment and involve complex analysis:

§
depreciation methods and estimated useful lives of property, plant and equipment;

§
measuring recoverability of long-lived assets and equity method investments;

§
amortization methods and estimated useful lives of qualifying intangible assets;

§
methods we employ to measure the fair value of goodwill; and

§
revenue recognition policies and the use of estimates for revenue and expenses.

When used to prepare our Unaudited Condensed Consolidated Financial Statements, the foregoing types of estimates are based on our current knowledge and understanding of the underlying facts and circumstances.  Such estimates may be revised as a result of changes in the underlying facts and circumstances.  Subsequent changes in these estimates may have a significant impact on our consolidated financial position, results of operations and cash flows.



Other Items

Contractual Obligations

Our consolidated principal debt obligations at September 30, 2018 were approximately $26.13 billion compared to $24.78 billion at December 31, 2017.  For information regarding the scheduled maturities of such debt, see “Liquidity and Capital Resources – Consolidated Debt” within this Part I, Item 2.  See Note 7 of the Notes to Unaudited Condensed Consolidated Financial Statements under Part I, Item 1 of this quarterly report for additional information regarding our consolidated debt obligations.

During the first nine months of 2018, we entered into long-term product purchase commitments for crude oil with third party suppliers in order to meet future physical delivery obligations on our various systems.  On a combined basis, these agreements increased our estimated long-term purchase obligations by approximately $1.2 billion over the next five years and $1.8 billion overall.  Apart from these new agreements, there have been no other material changes in our consolidated purchase obligations since those reported in our 2017 Form 10-K.

Off-Balance Sheet Arrangements

We have no off-balance sheet arrangements that have or are reasonably expected to have a material current or future effect on our financial position, results of operations and cash flows.

Recent Accounting Developments

For information regarding recent developments involving changes in our accounting policies for revenue recognition, the presentation of restricted cash on the cash flow statement, and our work involving the new lease accounting standard, see Note 2 of the Notes to Unaudited Condensed Consolidated Financial Statements included under Part I, Item 1 of this quarterly report.

Related Party Transactions

For information regarding our related party transactions, see Note 15 of the Notes to Unaudited Condensed Consolidated Financial Statements included under Part I, Item 1 of this quarterly report.


Item 3.                  Quantitative and Qualitative Disclosures About Market Risk.

General

In the normal course of our business operations, we are exposed to certain risks, including changes in interest rates and commodity prices.  In order to manage risks associated with assets, liabilities and certain anticipated future transactions, we use derivative instruments such as futures, forward contracts, swaps and other instruments with similar characteristics.  Substantially all of our derivatives are used for non-trading activities.

We assess the risk associated with each of our derivative instrument portfolios using a sensitivity analysis model.  This approach measures the change in fair value of the derivative instrument portfolio based on a hypothetical 10% change in the underlying interest rates or quoted market prices on a particular day.  In addition to these variables, the fair value of each portfolio is influenced by changes in the notional amounts of the instruments outstanding and the discount rates used to determine the present values.  The sensitivity analysis approach does not reflect the impact that the same hypothetical price movement would have on the hedged exposures to which they relate.  Therefore, the impact on the fair value of a derivative instrument resulting from a change in interest rates or quoted market prices (as applicable) would normally be offset by a corresponding gain or loss on the hedged debt instrument, inventory value or forecasted transaction assuming:

§
the derivative instrument functions effectively as a hedge of the underlying risk;

§
the derivative instrument is not closed out in advance of its expected term; and

§
the hedged forecasted transaction occurs within the expected time period.

We routinely review the effectiveness of our derivative instrument portfolios in light of current market conditions.  Accordingly, the nature and volume of our derivative instruments may change depending on the specific exposure being managed.

See Note 14 of the Notes to Unaudited Condensed Consolidated Financial Statements included under Part I, Item 1 of this quarterly report for additional information regarding our derivative instruments and hedging activities.

Commodity Hedging Activities

The prices of natural gas, NGLs, crude oil, petrochemicals and refined products are subject to fluctuations in response to changes in supply and demand, market conditions and a variety of additional factors that are beyond our control.  In order to manage such price risks, we enter into commodity derivative instruments such as physical forward contracts, futures contracts, fixed-for-float swaps, basis swaps and option contracts.  The following table summarizes our portfolio of commodity derivative instruments outstanding at September 30, 2018 (volume measures as noted):

(4)   Reflects the use of derivative instruments to manage risks associated with transportation, processing and storage assets.

At September 30, 2018, our predominant commodity hedging strategies consisted of (i) hedging anticipated future purchases and sales of commodity products associated with transportation, storage and blending activities, (ii) hedging natural gas processing margins and (iii) hedging the fair value of commodity products held in inventory.  

§
The objective of our anticipated future commodity purchases and sales hedging program is to hedge the margins of certain transportation, storage, blending and operational activities by locking in purchase and sale prices through the use of derivative instruments and related contracts.

§
The objective of our natural gas processing hedging program is to hedge an amount of earnings associated with these activities.  We achieve this objective by executing fixed-price sales for a portion of our expected equity NGL production using derivative instruments and related contracts.  For certain natural gas processing contracts, the hedging of expected equity NGL production also involves the purchase of natural gas for shrinkage, which is hedged using derivative instruments and related contracts.

§
The objective of our inventory hedging program is to hedge the fair value of commodity products currently held in inventory by locking in the sales price of the inventory through the use of derivative instruments and related contracts.

The derivative liability for our crude oil marketing hedges increased from $65.5 million at December 31, 2017 to $336.2 million at September 30, 2018, which resulted in a $270.7 million decrease in the fair value of the crude oil marketing portfolio for the nine months ended September 30, 2018. The derivative liability for the portfolio improved to $323.4 million at October 15, 2018 primarily due to lower crude oil futures prices as well as a narrowing of the crude oil basis spreads since September 30, 2018.  As noted in our discussion of results for the Crude Oil Pipelines & Services segment within Part I, Item 2 of this quarterly report, we entered into hedges of the crude oil commodity price differentials between the Midland and Houston markets and the Midland and Cushing markets.

Assuming no changes subsequent to September 30, 2018 in the variables used to determine the portfolio’s fair value, the derivative liability of $336.2 million at September 30, 2018 would be reversed upon cash settlement of the underlying hedges, which would create unrealized mark-to-market gains in net income and other comprehensive income as follows for the periods indicated (dollars in millions):

As the non-cash, mark-to-market gains attributable to the financial hedges are recognized in earnings, the corresponding actual losses on the financial hedges and related gains on the physical transactions will be simultaneously realized.

At September 30, 2018, approximately 68% of the Midland-to-ECHO Pipeline’s uncommitted capacity available to us through 2020 was not hedged, thereby providing us with potential upside to widening or downside to narrowing market spreads.   The value of this unhedged capacity was approximately $439.8 million assuming that we hedged all such capacity at the prevailing crude oil commodity price differentials between Midland and Houston as of September 30, 2018.

The posting of additional cash may be required to maintain our commodity derivative instruments portfolio as prices fluctuate or margin requirements change.  Our restricted cash balance decreased from $248.9 million at September 30, 2018 to $235.0 million at October 15, 2018.  In addition, we posted $211.7 million of cash and $100.0 million under stand-by letters of credit in connection with margin requirements on the Chicago Mercantile Exchange through October 15, 2018. The decrease in restricted cash and other cash postings since September 30, 2018 is primarily due to changes in the initial margin requirements and fair value of our crude oil marketing transportation hedges.

Interest Rate Hedging Activities

We may utilize interest rate swaps, forward starting swaps and similar derivative instruments to manage our exposure to changes in interest rates charged on borrowings under certain consolidated debt agreements.  This strategy may be used in controlling our overall cost of capital associated with such borrowings.  The composition of our derivative instrument portfolios may change depending on our hedging requirements. We have no interest rate hedging instruments outstanding as of the filing date of this quarterly report.


Item 4.               Controls and Procedures.

Disclosure Controls and Procedures

As of the end of the period covered by this quarterly report, our management carried out an evaluation, with the participation of (i) A. James Teague, our general partner’s Chief Executive Officer and (ii) W. Randall Fowler, our general partner’s President and Chief Financial Officer, of the effectiveness of our disclosure controls and procedures pursuant to Rule 13a-15 of the Securities Exchange Act of 1934.  Mr. Teague is our principal executive officer and Mr. Fowler is our principal financial officer.  Based on this evaluation, as of the end of the period covered by this quarterly report, Messrs. Teague and Fowler concluded:

(i)
that our disclosure controls and procedures are designed to ensure that information required to be disclosed by us in the reports that we file or submit under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our principal executive and financial officers, as appropriate to allow for timely decisions regarding required disclosures; and

(ii)
that our disclosure controls and procedures are effective.

Changes in Internal Control over Financial Reporting

There were no changes in our internal controls over financial reporting (as defined in Rule 13a-15(f) under the Securities Exchange Act of 1934) during the third quarter of 2018, that have materially affected, or are reasonably likely to materially affect, our internal controls over financial reporting. 

Section 302 and 906 Certifications

The required certifications of Messrs. Teague and Fowler under Sections 302 and 906 of the Sarbanes-Oxley Act of 2002 are included as exhibits to this quarterly report (see Exhibits 31 and 32 under Part II, Item 6 of this quarterly report).

PART II.  OTHER INFORMATION

Item 1. 
Legal Proceedings.

As part of our normal business activities, we may be named as defendants in litigation and legal proceedings, including those arising from regulatory and environmental matters.  Although we are insured against various risks to the extent we believe it is prudent, there is no assurance that the nature and amount of such insurance will be adequate, in every case, to indemnify us against liabilities arising from future legal proceedings.  We will vigorously defend the partnership in litigation matters.

For additional information regarding our litigation matters, see “Litigation” under Note 16 of the Notes to Unaudited Condensed Consolidated Financial Statements included under Part I, Item 1 of this quarterly report, which subsection is incorporated by reference into this Part II, Item 1.


Item 1A.                 Risk Factors.

An investment in our securities involves certain risks. Security holders and potential investors in our securities should carefully consider the risks described under “Risk Factors” set forth in Part I, Item 1A of our 2017 Form 10-K, in addition to other information in such annual report.  The risk factors set forth in our 2017 Form 10-K are important factors that could cause our actual results to differ materially from those contained in any written or oral forward-looking statements made by us or on our behalf.
