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 EPD’s 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 14 for information regarding related party matters.
Our results of operations for the nine months ended September 30, 2019 are not necessarily indicative of results expected for the full year of 2019. 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”).

See Note 13 for information regarding our derivative instruments and hedging activities.
Recent Accounting Developments
Lease accounting standard
In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Codification (“ASC”) 842, Leases, which requires substantially all leases be recorded on the balance sheet. We adopted the new standard on January 1, 2019 and applied 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 supersedes existing lease accounting guidance found under ASC 840, Leases.
The new standard introduces two lessee accounting models, which result in a lease being classified as either a “finance” or “operating” lease based on 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 ASC 840 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. For finance leases, a lessee will amortize the ROU asset (generally on a straight-line basis in a manner similar to depreciation) and accrete the lease liability (as a component of interest expense) using the effective interest method. Operating leases will result in the recognition of a single lease expense amount that is recorded on a straight-line basis.

ENTERPRISE PRODUCTS PARTNERS L.P.
NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
ASC 842 resulted 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 recognized a ROU asset and a corresponding lease liability based on the present value of then existing long-term operating lease obligations. In addition, we elected to apply several practical expedients and made accounting policy elections 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 reassess whether any expired or existing contracts contain leases or the lease classification for any existing or expired leases.

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

| • | We will combine lease and nonlease components relating to our office and warehouse leases, as applicable.

See Note 15 for our disclosures regarding operating lease obligations.
Note 3. Inventories
Our inventory amounts by product type were as follows at the dates indicated:

|  | September 30, 2019 |  |  | December 31, 2018 |
NGLs |  | $ | 928.2 |  |  | $ | 647.7 |
Petrochemicals and refined products |  |  | 183.2 |  |  |  | 264.7 |
Crude oil |  |  | 520.1 |  |  |  | 593.4 |
Natural gas |  |  | 13.2 |  |  |  | 16.3 |
Total |  | $ | 1,644.7 |  |  | $ | 1,522.1 |

Due to fluctuating commodity prices, we recognize lower of cost or net realizable value adjustments when the carrying value of our available-for-sale inventories exceeds their net realizable value. The following table presents our total cost of sales amounts and lower of cost or net realizable value adjustments for the periods indicated:

| For the Three Months Ended September 30, |  | For the Nine Months Ended September 30, |
| 2019 |  | 2018 |  | 2019 |  | 2018 |
Cost of sales (1) |  | $ | 5,276.5 |  |  | $ | 6,838.9 |  |  | $ | 16,721.5 |  |  | $ | 20,371.2 |
Lower of cost or net realizable value adjustments recognized within cost of sales |  |  | 6.8 |  |  |  | 1.7 |  |  |  | 17.1 |  |  |  | 4.3 |

(1) | Cost of sales is a component of “Operating costs and expenses” as presented on our Unaudited Condensed Statements of Consolidated Operations. Fluctuations in these amounts are primarily due to changes in energy commodity prices and sales volumes associated with our marketing activities.

(3) | Transportation equipment includes tractor-trailer tank trucks and other vehicles and similar assets used in our operations.
(4) | Marine vessels include tow boats, barges and related equipment used in our marine transportation business.
(5) | In general, the estimated useful lives of major assets within this category are: processing plants, 20-35 years; pipelines and related equipment, 5-45 years; terminal facilities, 10-35 years; buildings, 20-40 years; office furniture and equipment, 3-20 years; and laboratory and shop equipment, 5-35 years.
(6) | In general, the estimated useful lives of assets within this category are: underground storage facilities, 5-35 years; storage tanks, 10-40 years; and water wells, 5-35 years.

The following table summarizes our depreciation expense and capitalized interest amounts for the periods indicated:

| For the Three Months Ended September 30, |  | For the Nine Months Ended September 30, |
| 2019 |  | 2018 |  | 2019 |  | 2018 |
Depreciation expense (1) |  | $ | 394.7 |  |  | $ | 368.3 |  |  | $ | 1,164.6 |  |  | $ | 1,061.1 |
Capitalized interest (2) |  |  | 33.9 |  |  |  | 28.1 |  |  |  | 102.9 |  |  |  | 113.4 |

(1) | Depreciation expense is a component of “Costs and expenses” as presented on our Unaudited Condensed Statements of Consolidated Operations.
(2) | We capitalize interest costs incurred on funds used to construct property, plant and equipment while the asset is in its construction phase. The capitalized interest is recorded as part of the asset to which it relates and is amortized over the asset’s estimated useful life as a component of depreciation expense. When capitalized interest is recorded, it reduces interest expense from what it would be otherwise.

Asset Retirement Obligations
Property, plant and equipment at September 30, 2019 and December 31, 2018 includes $66.4 million and $72.5 million, respectively, of asset retirement costs capitalized as an increase in the associated long-lived asset.

The following table presents the range of interest rates and weighted-average interest rates paid on our consolidated variable-rate debt during the nine months ended September 30, 2019:

| Range of Interest Rates Paid | Weighted-Average Interest Rate Paid
Commercial Paper Notes | 2.58% to 2.80% | 2.72%
EPO Junior Subordinated Notes C and TEPPCO Junior Subordinated Notes | 4.91% to 5.52% | 5.34%

Amounts borrowed under our 364-Day and Multi-Year Revolving Credit Agreements bear interest, at our election, equal to: (i) LIBOR, plus an additional variable spread; or (ii) an alternate base rate, which is the greater of (a) the Prime Rate in effect on such day, (b) the Federal Funds Effective Rate in effect on such day plus 0.5%, or (c) the LIBO Market Index Rate in effect on such day plus 1% and a variable spread. The applicable spreads are determined based on our debt ratings.
The following table presents the scheduled contractual maturities of principal amounts of our consolidated debt obligations at September 30, 2019 for the next five years and in total thereafter:

In October 2019, we repaid $800.0 million principal amount of EPO’s Senior Notes LL at their maturity using unrestricted cash on hand.
Parent-Subsidiary Guarantor Relationships
EPD 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, EPD would be responsible for full and unconditional repayment of that obligation.
Amendment to Multi-Year Revolving Credit Agreement
In September 2019, EPO entered into an amendment (the “First Amendment”) to its revolving credit agreement dated September 13, 2017 (the “Multi-Year Revolving Credit Agreement”). The First Amendment reduces the borrowing capacity under the Multi-Year Revolving Credit Agreement from $4.0 billion to $3.5 billion (which may be increased by up to $500 million to $4.0 billion at EPO’s election provided certain conditions are met) and extends the maturity date to September 10, 2024, although the maturity date may be extended further at EPO’s request by up to two years, with the consent of required lenders as set forth under the credit agreement. Borrowings under this revolving credit agreement may be used for working capital, capital expenditures, acquisitions and general company purposes.
The Multi-Year 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 Multi-Year Revolving 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 Multi-Year Revolving Credit Agreement are not secured by any collateral; however, they are guaranteed by Enterprise Products Partners L.P.

Renewal of 364-Day Revolving Credit Agreement
In September 2019, EPO entered into a new 364-Day Revolving Credit Agreement that replaced its prior 364-day credit facility. The new 364-Day Revolving Credit Agreement matures in September 2020. 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 $1.5 billion (which may be increased by up to $200 million to $1.7 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 non-revolving term loans for a period of one additional year, payable in September 2021. 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.

Issuance of $2.5 Billion of Senior Notes in July 2019
In July 2019, EPO issued $2.5 billion aggregate principal amount of senior notes comprised of $1.25 billion principal amount of senior notes due July 2029 (“Senior Notes YY”) and $1.25 billion principal amount of senior notes due January 2050 (“Senior Notes ZZ”). Net proceeds from this offering were used by EPO for the repayment of debt and for general company purposes, including for growth capital expenditures.
Senior Notes YY were issued at 99.955% of their principal amount and have a fixed interest rate of 3.125% per year. Senior Notes ZZ were issued at 99.792% of their principal amount and have a fixed interest rate of 4.20% per year. EPD has guaranteed the senior notes through an unconditional guarantee on an unsecured and unsubordinated basis.
Partial Retirement of Junior Subordinated Notes During Second Quarter of 2019
During the second quarter of 2019, EPO repurchased and retired $24.2 million in principal amount of its Junior Subordinated Notes C. A $1.5 million gain on the extinguishment of these debt obligations is included in “Other, net” on our Unaudited Condensed Statements of Consolidated Operations with respect to the nine months ended September 30, 2019.
Lender Financial Covenants
We were in compliance with the financial covenants of our consolidated debt agreements at September 30, 2019.
Letters of Credit
At September 30, 2019, EPO had $101.4 million of letters of credit outstanding primarily related to our commodity hedging activities.

We have a universal shelf registration statement (the “2019 Shelf”) on file with the SEC which allows EPD and EPO (each on a standalone basis) to issue an unlimited amount of equity and debt securities, respectively. The 2019 Shelf replaced our prior universal shelf registration statement, which expired in May 2019. EPO issued $2.5 billion of senior notes in July 2019 using the 2019 Shelf (see Note 7).
In addition, EPD has a registration statement on file with the SEC covering the issuance of up to $2.54 billion of its 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 its at-the-market (“ATM”) program. During the nine months ended September 30, 2019 and 2018, EPD did not issue any common units under its ATM program. After taking into account the aggregate sales price of common units sold under the ATM program through September 30, 2019, EPD has the capacity to issue additional common units under its ATM program up to an aggregate sales price of $2.54 billion.
We may issue additional equity and debt securities to assist us in meeting our future liquidity requirements, including those related to capital investments.
Common unit repurchases under 2019 Buyback Program
In January 2019, we announced that the Board of Enterprise GP had approved a $2.0 billion multi-year unit buyback program (the “2019 Buyback Program”), which provides EPD with an additional method to return capital to investors. The 2019 Buyback Program authorizes EPD to repurchase its common units from time to time, including through open market purchases and negotiated transactions. The timing and pace of buy backs under the program will be determined by a number of factors including (i) our financial performance and flexibility, (ii) organic growth and acquisition opportunities with higher potential returns on investment, (iii) EPD’s unit price and implied cash flow yield and (iv) maintaining targeted financial leverage with a debt-to-normalized adjusted EBITDA (earnings before interest, taxes, depreciation and amortization) ratio of approximately 3.5 times. No time limit has been set for completion of the program, and it may be suspended or discontinued at any time.
EPD repurchased 2,909,128 common units under the 2019 Buyback Program through open market purchases during the nine months ended September 30, 2019 (no repurchases were made during the third quarter of 2019). The total purchase price of these repurchases was $81.1 million, excluding commissions and fees. The repurchased units were cancelled immediately upon acquisition. At September 30, 2019, the remaining available capacity under the 2019 Buyback Program was $1.92 billion.

Common units issued in connection with DRIP and EUPP
EPD has registration statements on file with the SEC in connection with its distribution reinvestment plan (“DRIP”) and employee unit purchase plan (“EUPP”). EPD issued and delivered a total of 2,601,727 new common units under the DRIP during the nine months ended September 30, 2019, which generated net cash proceeds of $73.7 million. During the nine months ended September 30, 2018, EPD issued and delivered 16,073,974 new common units under the DRIP, which generated net cash proceeds of $438.1 million. After taking into account the number of common units delivered under the DRIP through September 30, 2019, EPD has the capacity to deliver an additional 57,544,841 common units under this plan. The period-to-period decrease in net cash proceeds from the DRIP is primarily due to (i) lower reinvestments by privately held affiliates of EPCO in 2019, (ii) a reduction in the discount applicable to common unit purchases made under the DRIP from 2.5% to 0% beginning with the distribution paid in February 2019 and (iii) the election to satisfy delivery obligations under the DRIP using common units purchased on the open market, rather than issuing new common units, beginning with the distribution paid in August 2019.
EPD issued and delivered 296,263 new common units under the EUPP during the nine months ended September 30, 2019, which generated net cash proceeds of $8.5 million. During the nine months ended September 30, 2018, EPD issued and delivered 403,602 new common units under its EUPP, which generated net cash proceeds of $11.3 million. After taking into account the number of common units delivered under the EUPP through September 30, 2019, EPD may deliver an additional 4,763,149 common units under this plan.
Net cash proceeds from the issuance of new common units under the DRIP and EUPP during the nine months ended September 30, 2019 were used to temporarily reduce amounts outstanding under EPO’s commercial paper program and for general company purposes, including for growth capital expenditures.
In July 2019, EPD announced that, beginning with the quarterly distribution payment paid in August 2019, it would use common units purchased on the open market, rather than issuing new common units, to satisfy its delivery obligations under the DRIP and EUPP. This election is subject to change in future quarters depending on the partnership’s need for equity capital. In August 2019, a total of 1,410,020 common units were purchased on the open market and delivered to participants in connection with the DRIP and EUPP. Apart from $0.5 million attributable to the plan discount available to all participants in the EUPP, the funds used to effect these purchases were sourced from the DRIP and EUPP participants. No other partnership funds were used to satisfy these obligations. We plan to use open market purchases to satisfy DRIP and EUPP reinvestments in connection with the distribution expected to be paid on November 12, 2019.

In February 2019, certain employees of EPCO received discretionary bonus payments, less any retirement plan deductions and applicable withholding taxes, for work performed on our behalf during the prior fiscal year (e.g., the February 2019 bonus amount was applicable to the year ended December 31, 2018). The net dollar value of the bonus amounts was remitted through the issuance of an equivalent value of newly issued EPD common units under EPCO’s 2008 Enterprise Products Long-Term Incentive Plan (Third Amendment and Restatement) (“2008 Plan”). In February 2019, EPD issued 1,626,041 common units, which had a value of $45.6 million, in connection with the employee bonus awards. The compensation expense associated with each bonus award was recognized during the year in which the work was performed.
Common Units Issued in Connection With the Vesting of Phantom Unit Awards
During the nine months ended September 30, 2019, after taking into account tax withholding requirements, EPD issued a net 2,664,001 new common units to employees in connection with the vesting of phantom unit awards. See Note 12 for information regarding our phantom unit awards.

Cash Distributions
In January 2019, management announced its plans to recommend to the Board an increase of $0.0025 per unit per quarter in EPD’s cash distribution rate with respect to 2019. The anticipated rate of increase would result in distributions for 2019 of $1.7650 per unit, which would be 2.3% higher than those paid by EPD for 2018 of $1.7250 per unit. 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.
On October 9, 2019, EPD announced that the Board declared a cash distribution of $0.4425 per common unit with respect to the third quarter of 2019, which represents a 2.3% increase over the $0.4325 per common unit EPD declared and paid with respect to the third quarter of 2018. The distribution with respect to the third quarter of 2019 will be paid on November 12, 2019 to unitholders of record as of the close of business on October 31, 2019.

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 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.

Gross operating margin by segment is calculated by subtracting segment operating costs and expenses from segment revenues, with both segment totals reflecting the adjustments noted in the preceding table, as applicable, and before the elimination of intercompany transactions. The following table presents gross operating margin by segment for the periods indicated:

Fluctuations in our product sales revenues and related cost of sales amounts are explained in part by changes in energy commodity prices. In general, lower energy commodity prices result in a decrease in our revenues attributable to product sales; however, these lower commodity prices also decrease the associated cost of sales as purchase costs are lower. The same type of correlation would be true in the case of higher energy commodity sales prices and purchase costs.

Cash payments made in connection with DERs are nonforfeitable. As a result, the phantom units are considered participating securities for purposes of computing basic earnings per unit.

Note 12. Equity-Based Awards
An allocated portion of the fair value of EPCO’s equity-based awards is charged to us under the ASA. The following table summarizes compensation expense we recognized in connection with equity-based awards for the periods indicated:

|  | For the Three Months Ended September 30, |  |  | For the Nine Months Ended September 30, |

Total |  | $ | 37.3 |  |  | $ | 25.5 |  |  | $ | 107.8 |  |  | $ | 78.8 |

The fair value of equity-classified awards is amortized to earnings over the requisite service or vesting period. Equity-classified awards are expected to result in the issuance of common units upon vesting. Compensation expense for liability-classified awards is recognized over the requisite service or vesting period based on the fair value of the award remeasured at each reporting date. Liability-classified awards are settled in cash upon vesting.

Phantom Unit Awards
Phantom unit awards allow recipients to acquire EPD 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. The following table presents phantom unit award activity for the period indicated:

|  | Number of Units |  |  | Weighted- Average Grant Date Fair Value per Unit (1) |
Phantom unit awards at December 31, 2018 |  |  | 10,333,277 |  |  | $ | 26.97 |
Granted (2) |  |  | 6,851,920 |  |  | $ | 27.75 |
Vested |  |  | (3,810,666 | ) |  | $ | 27.54 |
Forfeited |  |  | (268,621 | ) |  | $ | 27.21 |
Phantom unit awards at September 30, 2019 |  |  | 13,105,910 |  |  | $ | 27.21 |

(1) | Determined by dividing the aggregate grant date fair value of awards (before an allowance for forfeitures) by the number of awards issued.
(2) | The aggregate grant date fair value of phantom unit awards issued during 2019 was $190.2 million based on a grant date market price of EPD common units ranging from $27.75 to $29.29 per unit. An estimated annual forfeiture rate of 3.0% was applied to these awards.

Each phantom unit award includes a DER, which entitles the recipient to receive cash payments equal to the product of the number of phantom unit awards and the cash distribution per unit paid to EPD’s common unitholders. Cash payments made in connection with DERs are nonforfeitable and charged to partners’ equity when the phantom unit award is expected to result in the issuance of common units; otherwise, such amounts are expensed.
The following table presents supplemental information regarding phantom unit awards for the periods indicated:

|  | For the Three Months Ended September 30, |  |  | For the Nine Months Ended September 30, |
|  | 2019 |  |  | 2018 |  |  | 2019 |  |  | 2018 |
Cash payments made in connection with DERs |  | $ | 5.9 |  |  | $ | 4.6 |  |  | $ | 16.4 |  |  | $ | 13.2 |
Total intrinsic value of phantom unit awards that vested during period |  |  | 7.2 |  |  |  | 4.5 |  |  |  | 108.9 |  |  |  | 89.6 |

The unrecognized compensation cost associated with phantom unit awards was $172.5 million at September 30, 2019, of which our share of the cost is currently estimated to be $144.2 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
EPCO has established five limited partnerships (referred to as “Employee Partnerships”) that serve as long-term incentive arrangements for key employees of EPCO by providing them a profits interest in one or more of the Employee Partnerships. At September 30, 2019, our share of the total unrecognized compensation cost related to the Employee Partnerships was $27.3 million, which we expect to recognize over a weighted-average period of 3.4 years.

Note 13. 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.
Interest Rate Hedging Activities
We may utilize interest rate swaps, forward-starting swaps, options to enter into forward-starting swaps (“swaptions”), 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.
Swaptions
In January and July 2019, we sold options to be put into forward-starting swaps, or swaptions, if the market rate of interest fell below the strike rate of the option upon expiration of the derivative instrument. The premiums we realized upon sale of the swaptions are reflected as a $13.3 million and $23.1 million reduction in interest expense for the three and nine months ended September 30, 2019, respectively.
Due to declining interest rates, the counterparties to the swaptions sold in July 2019 exercised their right to put us into ten forward-starting swaps on September 30, 2019 having an aggregate notional value of $1.0 billion on September 30, 2019. Forward-starting swaps hedge the risk of an increase in underlying benchmark interest rates during the period of time between the inception date of the swap agreement and the future date of debt issuance. Under the terms of the forward-starting swaps, we will pay to the counterparties (at the expected settlement dates of the instruments) amounts based on a 30-year fixed interest rate applied to the notional amount and receive from the counterparties an amount equal to a 30-year variable interest rate on the same notional amount. On September 30, 2019, the weighted-average fixed interest rate of the ten forward-starting swaps was 2.12%, which was 0.41% higher than the then applicable variable interest rate. As a result, we incurred an unrealized, mark-to-market loss at inception totaling $94.9 million that is reflected as an increase in interest expense for the three and nine months ended September 30, 2019. Prospectively, we will account for the forward-starting swaps as cash flow hedges, with any subsequent gains or losses on these derivative instruments reflected as a component of other comprehensive income and amortized to earnings (through interest expense) over the 30-year period of the associated future debt issuance.
Although we incurred a loss upon the exercise of these derivative instruments, we believe that the fixed interest rates that we will pay in connection with these forward-starting swaps are very favorable when compared to historical 30-year rates. Settlement of amounts accrued under the ten forward-starting swaps, including any gains or losses incurred from changes in interest rates between now and the contractual settlement dates, will occur at their respective expiration dates in September 2020 and April 2021.
Forward-Starting Swaps
The following table summarizes our portfolio of 30-year forward-starting swaps at September 30, 2019, all of which are associated with the expected future issuance of senior notes.

Hedged Transaction | Number and Type of Derivatives Outstanding | Notional Amount | Expected Settlement Date | Weighted-Average Fixed Rate Locked | Accounting Treatment
Future long-term debt offering | 1 forward-starting swap (1) | $75.0 | 9/2020 | 2.39% | Cash flow hedge
Future long-term debt offering | 1 forward-starting swap (1) | $75.0 | 4/2021 | 2.41% | Cash flow hedge
Future long-term debt offering | 5 forward-starting swaps (2) | $500.0 | 9/2020 | 2.12% | Cash flow hedge
Future long-term debt offering | 5 forward-starting swaps (2) | $500.0 | 4/2021 | 2.13% | Cash flow hedge

(1) | These swaps were entered into in May 2019.
(2) | These swaps were entered into in September 2019 as a result of the swaption exercise.

In total, the notional amount of forward-starting swaps outstanding at September 30, 2019 was $1.15 billion. The weighted-average fixed interest rate of these derivative instruments is 2.16%.

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, 2019, 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 following table summarizes our portfolio of commodity derivative instruments outstanding at September 30, 2019 (volume measures as noted):

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.

The $4.5 million loss recognized for the nine months ended September 30, 2019 (as noted in the preceding table) from designated as hedging instruments consists of (i) $0.7 million of realized losses and $91.1 million of net unrealized mark-to-market gains attributable to commodity derivatives and (ii) $94.9 million of unrealized mark-to-market losses attributable to interest rate derivatives.
In total and inclusive of both fair value hedges and derivatives not designated as hedging instruments, we recognized a net $2.0 million mark-to-market loss for the nine months ended September 30, 2019 consisting of (i) $92.9 million of net unrealized mark-to-market gains attributable to commodity derivatives and (ii) $94.9 million of unrealized mark-to-market losses attributable to interest rate derivatives.
Fair Value Measurements
The following tables set forth, by level within the Level 1, 2 and 3 fair value hierarchy, the carrying values of our financial assets and liabilities at the dates indicated. These assets and liabilities are measured on a recurring basis and are classified based on the lowest level of input used to estimate their fair value. Our assessment of the relative significance of such inputs requires judgment.

The values for commodity derivatives are presented before and after the application of Chicago Mercantile Exchange (“CME”) Rule 814, 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, 2019. 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.
The following table sets forth a reconciliation of changes in the fair values of our recurring Level 3 financial assets and liabilities on a combined basis for the periods indicated:

Nonrecurring Fair Value Measurements
Non-cash asset impairment charges for the nine months ended September 30, 2019 were $51.3 million compared to $21.4 million for the nine months ended September 30, 2018. Charges for 2019 primarily relate to assets retired during the quarter whose operations have ceased. Impairment charges are a component of “Operating costs and expenses” on our Unaudited Condensed Statements of Consolidated Operations.
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 $31.01 billion and $25.97 billion at September 30, 2019 and December 31, 2018, respectively. The aggregate carrying value of these debt obligations was $27.95 billion and $26.15 billion at September 30, 2019 and December 31, 2018, respectively. These values are primarily based on quoted market prices for such debt or debt of similar terms and maturities (Level 2) and our credit standing. 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.

At September 30, 2019, EPCO and its privately held affiliates (including Dan Duncan LLC and certain Duncan family trusts) beneficially owned the following limited partner interests in us:

Total Number of Units | Percentage of Total Units Outstanding
698,313,137 | 31.9%

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, 2019. 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 EPD’s 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, 2019 and 2018, we paid EPCO and its privately held affiliates cash distributions totaling $893.1 million and $867.4 million, respectively.
From time-to-time, EPCO and its privately held affiliates elect to purchase additional common units under EPD’s DRIP and ATM program. During the nine months ended September 30, 2019, privately held affiliates of EPCO reinvested $21.6 million through the DRIP. See Note 8 for additional information regarding the 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:

|  | For the Three Months Ended September 30, |  |  | For the Nine Months Ended September 30, |
|  | 2019 |  |  | 2018 |  |  | 2019 |  |  | 2018 |
Operating costs and expenses |  | $ | 259.3 |  |  | $ | 246.6 |  |  | $ | 732.0 |  |  | $ | 697.6 |
General and administrative expenses |  |  | 34.2 |  |  |  | 35.0 |  |  |  | 92.9 |  |  |  | 92.6 |
Total costs and expenses |  | $ | 293.5 |  |  | $ | 281.6 |  |  | $ | 824.9 |  |  | $ | 790.2 |

We lease office space from privately held affiliates of EPCO. The rental rates in these lease agreements approximate market rates. For the three and nine months ended September 30, 2019, we recognized $3.8 million and $11.1 million, respectively, of related party operating lease expense in connection with these office space leases. For the three and nine months ended September 30, 2018, we recognized $3.8 million and $10.7 million, respectively, of related party operating lease expense for these leases.
Note 15. 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.
Our accruals for litigation contingencies were $0.5 million at September 30, 2019 and December 31, 2018 and recorded in our Unaudited Condensed Consolidated Balance Sheets as a component of “Other current liabilities.”

Energy Transfer 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 trial 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 trial 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 Dallas 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 $0.8 million, plus interest. On August 31, 2017, ETP filed a motion for rehearing before the Dallas Court of Appeals, which was denied on September 13, 2017. 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 filed their respective submittals. On June 28, 2019, the Supreme Court of Texas requested oral argument, which was held on October 8, 2019.
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 (“OPD”), 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. In total, the principal amount of our consolidated debt obligations were $28.20 billion and $26.42 billion at September 30, 2019 and December 31, 2018, respectively. See Note 7 for additional information regarding our scheduled future maturities of debt principal.
Lease Accounting Matters
The following table presents information regarding our operating leases where we are the lessee at September 30, 2019:

Asset Category | ROU Asset Carrying Value (1) |  | Lease Liability Carrying Value (2) |  | Weighted- Average Remaining Term |  | Weighted- Average Discount Rate (3)
Storage and pipeline facilities | $ | 141.0 |  | $ | 141.6 |  | 16 years |  | 4.3%
Transportation equipment |  | 54.2 |  |  | 56.6 |  | 4 years |  | 3.4%
Office and warehouse space |  | 24.3 |  |  | 22.9 |  | 2 years |  | 3.5%
Total | $ | 219.5 |  | $ | 221.1 |  |  |  |

(1) | ROU asset amounts are a component of “Other assets” on our consolidated balance sheet.
(2) | At September 30, 2019, lease liabilities of $39.2 million and $181.9 million were included within “Other current liabilities” and “Other liabilities,” respectively.
(3) | The discount rate for each category of assets represents the weighted average of either (i) the implicit rate applicable to the underlying leases (where determinable) or (ii) our incremental borrowing rate adjusted for collateralization (if the implicit rate is not determinable). In general, the discount rates are based on either (i) information available at the lease commencement date or (ii) January 1, 2019 for leases existing at the adoption date for ASC 842.

The following table disaggregates our operating lease expense for the periods indicated:

|  | For the Three Months Ended September 30, 2019 |  |  | For the Nine Months Ended September 30, 2019 |
Long-term operating leases: |  |  |  |  |  |
Fixed lease expense |  | $ | 12.8 |  |  | $ | 39.3 |
Variable lease expense |  |  | 1.6 |  |  |  | 4.5 |
Subtotal operating lease expense |  |  | 14.4 |  |  |  | 43.8 |
Short-term lease expense |  |  | 12.4 |  |  |  | 35.9 |
Total operating lease expense |  | $ | 26.8 |  |  | $ | 79.7 |

In total, operating lease expense was $26.8 million and $27.6 million for the three months ended September 30, 2019 and 2018, respectively. During the nine months ended September 30, 2019 and 2018 operating lease expense was $79.7 million and $79.0 million, respectively. Operating lease expense represents less than 1% of “Operating costs and expenses” as presented on our consolidated statements of operations. Fixed lease expense is charged to earnings on a straight-line basis over the contractual term, with any variable lease payments expensed as incurred. Short-term lease expense is expensed as incurred.
We recognized $246.1 million in ROU assets and lease liabilities for long-term operating leases at January 1, 2019 in connection with the adoption of ASC 842. These amounts represented less than 1% of our total consolidated assets and liabilities, respectively, at the adoption date. On an undiscounted basis, our long-term operating lease obligations aggregated to $314.4 million at January 1, 2019.

Under ASC 842, lessors classify leases as either operating, direct financing or sales-type. We do not have any significant operating or direct financing leases. Our operating lease income for the three and nine months ended September 30, 2019 was $3.5 million and $10.7 million, respectively, which represented less than 1% of our consolidated revenues. We do not have any sales-type leases.
Our operating lease commitments at September 30, 2019 did not differ materially from those reported in our 2018 Form 10-K.
Purchase Obligations
During the nine months ended September 30, 2019, we entered into additional long-term purchase commitments for NGLs with third-party suppliers. On a combined basis, these new agreements increased our estimated long-term purchase obligations by $3.6 billion, with $1.3 billion committed over the next five years and $2.3 billion thereafter. At September 30, 2019, our estimated long-term purchase obligations totaled $12.7 billion after reflecting the agreements added during the first nine months of 2019 and those commitments that expired during the year. At December 31, 2018, our estimated long-term purchase obligations totaled $10.8 billion.
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 (“M&B”), a German corporation and the ultimate parent company of OTA, in connection with the first step of the Oiltanking acquisition in 2014 (“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 EPD common units then owned by OTA, currently 54,807,352 units, and assume all future income tax obligations of OTA associated with (i) owning common units encumbered by the 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.
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 $513.1 million and $390.0 million at September 30, 2019 and December 31, 2018, 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 held by OTA and reflect certain tax planning strategies we believe could be employed.
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. Results for the three and nine months ended September 30, 2019 include $38.7 million and $123.1 million, respectively, of non-cash expense attributable to the Liquidity Option. Expense recognized during 2019 is primarily due to a decrease in the applicable midstream industry weighted-average cost of capital, which is used as the discount factor in determining the present value of the liability, since December 31, 2018. The remainder of the inputs to the valuation model have not materially changed since those reported under Note 17 of the 2018 Form 10-K.

Acquisition of 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. As a result, Delaware Processing became our wholly-owned consolidated subsidiary. 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 during 2018.

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 EPD’s 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.

Significant Recent Developments
Enterprise to Expand Appalachia-to-Texas (“ATEX”) Pipeline
In October 2019, we announced an expansion of our ATEX ethane pipeline based on customer commitments received during a recent 30-day binding open season. The 1,192-mile ATEX pipeline transports ethane from the Marcellus/Utica Basin of Pennsylvania, West Virginia and Ohio to our NGL storage complex in Mont Belvieu, Texas. The current capacity of ATEX is approximately 145 MBPD, which would be expanded to 190 MBPD in connection with this expansion project. The incremental capacity is expected to be achieved through improvements and modifications to existing infrastructure. We anticipate that this expansion project will be completed in 2022.
Enterprise to Build Midland-to-ECHO 4 Pipeline; Conversion of Crude Oil Pipeline back to NGL Service
In October 2019, we announced long-term agreements that support a further expansion of our Midland-to-ECHO crude oil pipeline network. As part of such expansion, we plan to construct a fourth pipeline (the “Midland-to-ECHO 4” pipeline) that will connect our Midland terminal in Midland, Texas with our ECHO terminal in Houston, Texas utilizing both new construction and segments of our existing crude oil pipelines in South Texas. The Midland-to-ECHO 4 pipeline is expected to have an initial transportation capacity of 450 MBPD and can be expanded up to 540 MBPD.
When placed into service, the Midland-to-ECHO 4 pipeline will allow our shippers with crude oil and condensate production in both the Permian Basin and the Eagle Ford shale to maximize the value of their contracted pipeline capacity by allowing shippers to source barrels from the Permian Basin and/or the Eagle Ford shale. This unmatched flexibility will allow shippers and producers to dynamically match their pipeline capacity to their allocation of capital and respective production profiles between the two basins. Their production will be delivered into our integrated storage, pipeline, distribution and marine terminal system that has access to both domestic and international markets.
The Midland-to-ECHO 4 pipeline complements our Midland-to-ECHO 1 and 2 pipelines, which entered service in the second quarter of 2018 and first quarter of 2019, respectively, as well as an expansion project we announced in July 2019 (which we refer to as the “Midland-to-ECHO 3” project). The Midland-to-ECHO 3 and Midland-to-ECHO 4 projects are expected to begin service during the third quarter of 2020 and first half of 2021, respectively. Similar to the Midland-to-ECHO 4 project, the Midland-to-ECHO 3 pipeline is expected to add an incremental 450 MBPD of transportation capacity. Together, these four projects (Midland-to-ECHO 1, 2, 3 and 4) comprise our Midland-to-ECHO crude oil pipeline network, which supports crude oil production growth from the Permian Basin (and Eagle Ford shale, as applicable) by providing producers and other shippers with transportation solutions that are both cost-efficient and operationally flexible. The Midland-to-ECHO network is expected to include 6 MMBbls of storage at our Midland terminal and access to more than 45 MMBbls of storage and approximately 4 MMBPD of export capacity at partnership assets along the Texas Gulf Coast. The network connects to every refinery in the Houston, Texas City and Beaumont/Port Arthur area, representing approximately 4.5 MMBPD of refining capacity.
In January 2019, we converted the Midland-to-Sealy segment of one of our two Seminole NGL pipelines from NGL service to crude oil service, thus creating the major segment of the Midland-to-ECHO 2 pipeline. In April 2019, our Midland-to-ECHO 2 pipeline, which provides us with approximately 200 MBPD of incremental crude oil transportation capacity, was placed into full service after being in limited service since February 2019. Following the in-service date of the Midland-to-ECHO 4 pipeline, we plan to convert the Midland-to-Sealy segment of the Midland-to-ECHO 2 pipeline back to NGL service (as part of our Seminole NGL Pipeline) based upon our expectation that NGL production from the Permian Basin will increase by over 50 percent by 2025. The reconversion project is expected to take less than sixty days and be completed during the second half of 2021. We will retain the flexibility to convert the Midland-to-Sealy segment back into crude oil service should market conditions support the need for additional crude oil transportation capacity in the future.

Enterprise to Build Second Propane Dehydrogenation (“PDH”) Plant
In September 2019, we announced the execution of long-term contracts with affiliates of LyondellBasell Industries N.V. (“LyondellBasell”) that support construction of our second propane dehydrogenation plant (referred to as “PDH 2”). The new plant is expected to have the capacity to consume up to 35 MBPD of propane and produce up to 1.65 billion pounds per year of polymer grade propylene (“PGP”). PDH 2 will be located at our complex in the Mont Belvieu, Texas area. PDH 2 is scheduled to begin service in the first half of 2023.
The anchor contracts with LyondellBasell provide for us to process LyondellBasell-provided propane into PGP for a fixed fee. This fee-based model leverages our integrated value chain by providing sourcing and storage from our NGL storage facilities in Mont Belvieu, and delivers PGP into our storage hub and network of PGP pipeline infrastructure. Our network of PGP assets includes more than 300 miles of delivery pipelines, 5 MMBbls of storage capacity, and an export facility at our Enterprise Hydrocarbons Terminal (“EHT”) located on the Houston Ship Channel. We are currently expanding our PGP refrigeration facilities at EHT, which will enable us to load more than 5,000 barrels per hour of PGP, as well as co-load PGP and LPG on very large gas carriers.
Our Mont Belvieu NGL fractionation and storage system supporting PDH 2 currently has 760 MBPD of NGL fractionation capacity, with another 300 MBPD under construction. In addition, our Mont Belvieu complex has more than 100 million barrels of NGL and petrochemical storage, which provides our customers with unparalleled reliability and flexibility. The integration of our PDH 1 and PDH 2 plants with our legacy propylene fractionation facilities provides us with significant operational flexibility, and a combined PGP supply of more than nine billion pounds per year.
Enterprise to Expand and Extend Acadian Gas System
In September 2019, we announced plans to expand and extend our Acadian Gas System in order to deliver growing natural gas production from the Haynesville Shale to the liquefied natural gas (“LNG”) market in South Louisiana. The Haynesville region currently produces approximately 11 Bcf/d of natural gas, which is expected to grow to approximately 14 Bcf/d by 2025.
The expansion project will include construction of an approximately 80-mile natural gas pipeline (the “Gillis Lateral”) extending from near Cheneyville, Louisiana to third-party pipeline interconnects near Gillis, Louisiana, including multiple pipelines serving regional LNG export facilities. The LNG market in South Louisiana and Southeast Texas includes facilities, including those under construction, featuring an aggregate 15 Bcf/d of export capacity. The Gillis Lateral will have a transportation capacity of approximately 1 Bcf/d. In addition to construction of the Gillis Lateral, we plan to increase the transportation capacity of the Haynesville Extension from 1.8 Bcf/d to 2.1 Bcf/d by adding horsepower at our compressor station in Mansfield, Louisiana.
The Mansfield project and construction of the Gillis Lateral are supported by long-term customer contracts and are expected to begin service in mid-2021. Once the expansion project is completed, we expect that our Acadian Gas System will be able to deliver up to 2.1 Bcf/d of Haynesville production into the LNG market, South Louisiana industrial complex and other pipeline interconnects that serve attractive southeastern U.S. markets.
Enterprise Announces Final Investment Decision Regarding Sea Port Oil Terminal
In July 2019, we announced long-term agreements with Chevron U.S.A Inc. (“Chevron”) that support the development of our Sea Port Oil Terminal (“SPOT”) in the Gulf of Mexico. Construction of SPOT remains subject to obtaining the required approvals and licenses from the federal Maritime Administration, which is currently reviewing our SPOT application. The long-term agreements with Chevron support our final investment decision in SPOT, subject to receiving the requisite governmental permits.
50

Table of Contents
The SPOT project consists of onshore and offshore facilities, including a fixed platform located approximately 30 nautical miles off the Brazoria County, Texas coast in approximately 115 feet of water. SPOT is designed to load Very Large Crude Carriers (“VLCCs”) at rates of approximately 85,000 barrels per hour. We believe that SPOT’s design meets or exceeds federal requirements for such facilities and, unlike existing and other proposed offshore terminals, is designed with a vapor control system to minimize emissions. SPOT would provide customers with an integrated export solution that leverages our extensive supply, storage and distribution network along the Gulf Coast, with access to approximately 6 MMBbls of crude oil supply and more than 300 MMBbls of storage.
We expect that U.S. crude oil exports will increase from approximately 3 MMBPD currently to more than 8 MMBPD by 2025, as production from domestic shale basins continues to increase. SPOT would initially provide up to 2 MMBPD of this capacity and be essential to balancing the market and meeting global demand for U.S. crude oil production.
Altus Acquires 33% Equity Interest in Shin Oak NGL Pipeline from Enterprise
In May 2018, in conjunction with a long-term NGL supply agreement, we granted Apache Midstream LLC (“Apache”) an option to acquire up to a 33% equity interest in our consolidated subsidiary that owns the Shin Oak NGL Pipeline (“Shin Oak”). In November 2018, Apache contributed this option to Altus Midstream Processing LP (“Altus”), which is a consolidated subsidiary of Apache. In July 2019, Altus exercised the option and acquired a 33% equity interest (effective July 31, 2019). As a result, we received a $440.7 million cash payment from Altus, which is included in contributions from noncontrolling interests as presented on our Unaudited Condensed Statements of Consolidated Cash Flows for the nine months ended September 30, 2019.
Shin Oak is a 658-mile pipeline that transports NGLs from the Permian Basin to our Mont Belvieu NGL fractionation and storage complex. In February 2019, the 24-inch diameter mainline segment of Shin Oak from Orla, Texas to Mont Belvieu was placed into limited commercial service with an initial transportation capacity of 250 MBPD. In June 2019, an additional pipeline segment, the 20-inch diameter Waha lateral, was placed into service. Shin Oak’s transportation capacity by the end of the third quarter of 2019 was 350 MBPD. When fully complete in the fourth quarter of 2019, Shin Oak is expected to have up to 550 MBPD of transportation capacity.
Enterprise Begins Service at Orla III; Update on Mentone Plant
In July 2019, we announced that the third processing train (“Orla III”) at our Orla cryogenic natural gas processing plant had commenced operations. Completion of Orla III increased our natural gas processing capacity at Orla to 900 MMcf/d and our equity NGL production rate in excess of 140 MBPD. Overall, we now have the capability to process up to 1.3 Bcf/d of natural gas and produce approximately 200 MBPD of NGLs in the Delaware Basin.
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 more than 40 MBPD of NGLs. The project is on schedule for completion in the first quarter of 2020 and is supported by a long-term acreage dedication agreement. In addition, we are actively negotiating contracts with producers to underwrite additional capacity at Mentone. When the Mentone plant is completed and placed into service, we expect to have an aggregate 1.6 Bcf/d of natural gas processing capacity and approximately 250 MBPD of NGL production from our processing plants in the Delaware Basin.
Expansion Projects at EHT
We estimate that exports of U.S. crude oil will increase from 3 MMBPD to 8 MMBPD and that LPG exports will double from 1.4 MMBPD to 2.8 MMBPD by 2025. Much of this growth is being driven by increasing production from the Permian Basin. In response to these trends, we announced in July 2019 three new expansion projects at EHT, located on the Houston Ship Channel, that will increase our capacity to load LPG, PGP and crude oil at the terminal.
51

Table of Contents
We are adding an eighth deep-water ship dock at EHT that is expected to increase our crude oil loading capacity by 840 MBPD, thereby increasing our overall nameplate crude oil loading capacity at EHT to 2.75 MMBPD, or nearly 83 MMBbls per month. The new dock is designed to accommodate a Suezmax vessel, which is the largest ship class that can navigate the Houston Ship Channel, and is scheduled to be placed into service during the fourth quarter of 2020.
Our current nameplate loading capacity for LPG at EHT is approximately 835 MBPD, with 175 MBPD of this loading capacity placed into service during the third quarter of 2019. The expansion project announced in July 2019 is expected to increase our LPG loading capacity at EHT by an additional 260 MBPD and be placed into service during the fourth quarter of 2020. When this latest expansion project is completed, EHT will have a nameplate LPG loading capacity of approximately 1.1 MMBPD, or 33 MMBbls per month.
Our current loading capacity at EHT for PGP is approximately 2,500 barrels per hour, or 60 MBPD, of semi-refrigerated product. In response to record international demand for PGP, we will expand our export capabilities at EHT to accommodate an incremental 2,800 barrels per hour, or approximately 67 MBPD, of semi- or fully-refrigerated PGP. With the addition of fully refrigerated volumes, this expansion project will enable EHT to co-load fully refrigerated PGP and LPG volumes onto the same vessel. Our PGP export expansion project is expected to be placed into service during the fourth quarter of 2020.
Enterprise to Extend Ethylene Pipeline Network
In May 2019, we announced plans to expand our ethylene pipeline and logistics system by constructing the Baymark ethylene pipeline in South Texas, which is a leading growth area for new ethylene crackers and related facilities. The Baymark pipeline will originate in the Bayport, Texas area of southeast Harris County and extend approximately 90 miles to Markham, Texas in Matagorda County. The pipeline is supported by long-term customer commitments and is scheduled to begin service in the fourth quarter of 2020. We will be the majority owner and operator of the new pipeline.
The Baymark pipeline will feature access to a high-capacity ethylene storage well that is under development at our Mont Belvieu complex, along with connectivity to our ethylene export terminal currently under construction at Morgan’s Point. The storage well is expected to be completed in the fourth quarter of 2019 and have a capacity of 600 million pounds of ethylene. Our ethylene export terminal at Morgan’s Point will have the capacity to export approximately 2.2 billion pounds of ethylene per year and is expected to begin service in the fourth quarter of 2019.
Enterprise Announces $2 Billion Unit Buyback Program
In January 2019, we announced that the Board of Enterprise GP had approved a $2.0 billion multi-year unit buyback program (the “2019 Buyback Program”), which provides EPD with an additional method to return capital to investors. The 2019 Buyback Program authorizes EPD to repurchase its common units from time to time, including through open market purchases and negotiated transactions. The timing and pace of buy backs under the program will be determined by a number of factors including (i) our financial performance and flexibility, (ii) organic growth and acquisition opportunities with higher potential returns on investment, (iii) EPD’s unit price and implied cash flow yield and (iv) maintaining targeted financial leverage with a debt-to-normalized adjusted EBITDA (earnings before interest, taxes, depreciation and amortization) ratio of approximately 3.5 times. No time limit has been set for completion of the program, and it may be suspended or discontinued at any time.
EPD repurchased 2,909,128 common units under the 2019 Buyback Program through open market purchases during the nine months ended September 30, 2019 (no repurchases were made during the third quarter of 2019). The total purchase price of these repurchases was $81.1 million, excluding commissions and fees. The repurchased units were cancelled immediately upon acquisition. At September 30, 2019, the remaining available capacity under the 2019 Buyback Program was $1.92 billion.

Enterprise Provides 2019 Distribution Guidance
In January 2019, management announced plans to recommend to the Board an increase of $0.0025 per unit per quarter in our cash distribution rate with respect to 2019. The anticipated rate of increase would result in distributions for 2019 of $1.7650 per unit, which would be 2.3% higher than those paid for 2018 of $1.7250 per unit. 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.
On October 9, 2019, we announced that the Board declared a cash distribution of $0.4425 per common unit with respect to the third quarter of 2019. This distribution will be paid on November 12, 2019 to unitholders of record as of the close of business on October 31, 2019.

(1) | Natural gas prices are based on Henry-Hub Inside FERC commercial index prices as reported by Platts, which is a division of McGraw Hill Financial, Inc.
(2) | NGL prices for ethane, propane, normal butane, isobutane and natural gasoline are based on Mont Belvieu Non-TET commercial index prices as reported by Oil Price Information Service.
(3) | Polymer grade propylene prices represent average contract pricing for such product as reported by IHS Chemical, a division of IHS Inc. (“IHS Chemical”). Refinery grade propylene prices represent weighted-average spot prices for such product as reported by IHS Chemical.
(4) | The “Indicative Gas Processing Gross Spread” represents a generic estimate of the gross economic benefit from extracting NGLs from natural gas production based on certain pricing assumptions. Specifically, it is the amount by which the assumed economic value of a composite gallon of NGLs at Mont Belvieu, Texas exceeds the value of the equivalent amount of energy in natural gas at Henry Hub, Louisiana (as presented in the table above). The indicative spread does not consider the operating costs incurred by a natural gas processing plant to extract the NGLs nor the transportation and fractionation costs to deliver the NGLs to market. In addition, the actual gas processing spread earned at each plant is determined by regional pricing and extraction dynamics. As presented in the table above, the indicative spread assumes that a gallon of NGLs is comprised of 47% ethane, 28% propane, 9% normal butane, 6% isobutane and 10% natural gasoline. The value of an equivalent amount of energy in natural gas to one gallon of NGLs is assumed to be 8.4% of the price of a MMBtu of natural gas at Henry Hub.

Fluctuations in our consolidated revenues and cost of sales amounts are explained in large part by changes in energy commodity prices, which fluctuate for a variety of reasons including supply and demand imbalances and geopolitical tensions. The weighted-average indicative market price for NGLs was $0.39 per gallon in the third quarter of 2019 versus $0.82 per gallon during the third quarter of 2018. Likewise, the weighted-average indicative market price for NGLs was $0.48 per gallon during the nine months ended September 30, 2019 compared to $0.72 per gallon during the same period in 2018.
A decrease in our consolidated marketing revenues due to lower energy commodity sales prices may not result in a decrease in gross operating margin or cash available for distribution, since our consolidated cost of sales amounts would also decrease due to comparable decreases in the purchase prices of the underlying energy commodities. The same type of correlation would be true in the case of higher 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 13 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.

Third Quarter of 2019 Compared to Third Quarter of 2018. Total revenues for the third quarter of 2019 decreased $1.62 billion when compared to the third quarter of 2018 primarily due to a net $1.61 billion decrease in marketing revenues. Revenues from the marketing of NGLs, petrochemicals and refined products decreased a combined net $1.38 billion quarter-to-quarter primarily due to lower sales prices, which accounted for a $2.04 billion decrease, partially offset by the effects of higher sales volumes, which resulted in a $657.3 million increase. Revenues from the marketing of natural gas decreased $149.0 million quarter-to-quarter primarily due to lower sales prices. Revenues from the marketing of crude oil decreased a net $79.0 million quarter-to-quarter primarily due to lower sales prices, which accounted for a $429.9 million decrease, partially offset by higher sales volumes, which resulted in a $350.9 million increase.
Revenues from midstream services for the third quarter of 2019 decreased $10.6 million when compared to the third quarter of 2018. Revenues from our natural gas processing plants decreased $125.5 million quarter-to-quarter primarily due to lower market values for the equity NGLs we receive as non-cash consideration for providing processing services to certain customers, which accounted for a $151.1 million decrease, partially offset by contributions from our recently completed Orla facility, which accounted for a $22.7 million increase. We recognize revenues related to the equity NGLs we receive under commodity-based contracts (once the processing service has been performed and we are entitled to such volumes) at market value.
Midstream service revenues from our pipeline assets increased $48.5 million quarter-to-quarter primarily due to contributions from our Midland-to-ECHO 2 pipeline, which commenced operations in February 2019. Revenues from our terminal assets increased $39.5 million quarter-to-quarter primarily due to an increase in loading volumes at EHT.
Lastly, revenues from our Mont Belvieu storage complex increased a combined $27.7 million quarter-to-quarter primarily due to higher storage, throughput and other fees.
Nine Months Ended September 30, 2019 Compared to Nine Months Ended September 30, 2018. Total revenues for the nine months ended September 30, 2019 decreased $2.57 billion when compared to the nine months ended September 30, 2018 primarily due to a $2.76 billion decrease in marketing revenues. Revenues from the marketing of NGLs, petrochemicals and refined products decreased a combined net $1.61 billion period-to-period primarily due to lower sales prices, which accounted for a $3.15 billion decrease, partially offset by higher sales volumes, which resulted in a $1.54 billion increase. Revenues from the marketing of crude oil decreased $1.09 billion period-to-period primarily due to lower sales volumes, which accounted for a $906.0 million decrease, and lower sales prices, which resulted in an additional $186.8 million decrease.
Revenues from midstream services for the nine months ended September 30, 2019 increased $192.5 million when compared to the nine months ended September 30, 2018. Revenues from our pipeline assets increased $234.9 million period-to-period primarily due to strong demand for transportation services in Texas. Our Midland-to-ECHO 1 and 2 pipelines accounted for a combined $160.2 million of this increase. Revenues from our Mont Belvieu storage complex increased a combined $76.2 million period-to-period primarily due to higher storage, throughput and other fees. In addition, revenues from our terminal assets increased $56.6 million period-to-period primarily due to an increase in loading volumes at EHT. These increases were partially offset by lower revenues from our natural gas processing plants of $188.3 million period-to-period primarily due to lower market values for the equity NGLs we receive as non-cash consideration, which accounted for a $275.3 million decrease, partially offset by contributions from our recently completed Orla facility, which accounted for a $131.8 million increase.
Operating costs and expenses
Third Quarter of 2019 Compared to Third Quarter of 2018. Total operating costs and expenses for the third quarter of 2019 decreased $1.43 billion when compared to the third quarter of 2018 primarily due to lower cost of sales. The cost of sales associated with our marketing of NGLs, petrochemicals and refined products decreased a combined $1.47 billion quarter-to-quarter primarily due to lower purchase prices, which accounted for a $2.06 billion decrease, partially offset by higher sales volumes, which accounted for a $590.4 million increase. Other operating costs and expenses increased a net $55.1 million quarter-to-quarter primarily due to higher maintenance, power, chemical and employee compensation costs, which accounted for a combined $50.9 million increase.
56

Table of Contents
Depreciation, amortization and accretion expense increased $37.7 million quarter-to-quarter primarily due to assets placed into service since the third quarter of 2018 (e.g., the Shin Oak and Midland-to-ECHO 2 pipelines). Non-cash asset impairment charges increased $34.8 million quarter-to-quarter primarily due to the planned shutdown of certain natural gas processing plant and pipeline assets in South Texas and South Louisiana.
Nine Months Ended September 30, 2019 Compared to Nine Months Ended September 30, 2018. Total operating costs and expenses for the nine months ended September 30, 2019 decreased $3.38 billion when compared to the nine months ended September 30, 2018 primarily due to lower cost of sales. The cost of sales associated with our marketing of NGLs, petrochemicals and refined products decreased a combined net $1.77 billion period-to-period primarily due to lower purchase prices, which accounted for a $3.25 billion decrease, partially offset by higher sales volumes, which accounted for a $1.48 billion increase. The cost of sales associated with our marketing of crude oil decreased $1.69 billion period-to-period primarily due to lower purchase prices, which accounted for a $947.3 million decrease, and lower sales volumes, which accounted for an additional $744.7 million decrease.
Other operating costs and expenses for the nine months ended September 30, 2019 increased a net $100.3 million period-to-period primarily due to higher maintenance and chemical expenses, ad valorem taxes, and employee compensation costs, which accounted for a combined $124.0 million increase. These costs were partially offset by $33.9 million of expense recognized in the nine months ended September 30, 2018 in connection with our earnings allocation arrangement with an affiliate of Western Midstream Partners, LP (“Western”) involving the Midland-to-ECHO 1 pipeline.
Depreciation, amortization and accretion expense increased $131.8 million period-to-period primarily due to assets placed into full or limited service since the third quarter of 2018. Non-cash asset impairment charges increased $29.8 million period-to-period primarily due to the planned shutdown of certain natural gas processing assets in Texas and Louisiana (as noted previously).
General and administrative costs
General and administrative costs for the three and nine months ended September 30, 2019 increased $2.8 million and $3.1 million, respectively, when compared to the same periods in 2018 primarily due to higher employee-related costs.
Equity in income of unconsolidated affiliates
Equity income from our unconsolidated affiliates for the three and nine months ended September 30, 2019 increased $27.3 million and $81.3 million, respectively, when compared to the same periods in 2018 primarily due to increases in earnings from our investments in crude oil pipelines.
Operating income
Operating income for the three and nine months ended September 30, 2019 decreased $169.1 million and increased $892.5 million, respectively, when compared to the same periods in 2018 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
The following table presents the components of our consolidated interest expense for the periods indicated (dollars in millions):

|  | For the Three Months Ended September 30, |  |  | For the Nine Months Ended September 30, |
|  | 2019 |  |  | 2018 |  |  | 2019 |  |  | 2018 |
Interest charged on debt principal outstanding |  | $ | 319.3 |  |  | $ | 296.5 |  |  | $ | 934.2 |  |  | $ | 886.3 |
Impact of interest rate hedging program, including related amortization (1) |  |  | 90.3 |  |  |  | (1.7 | ) |  |  | 97.9 |  |  |  | (0.5 | )
Interest costs capitalized in connection with construction projects (2) |  |  | (33.9 | ) |  |  | (28.1 | ) |  |  | (102.9 | ) |  |  | (113.4 | )

Total |  | $ | 382.9 |  |  | $ | 279.5 |  |  | $ | 950.2 |  |  | $ | 806.2 |

(1) | Amount presented for the three and nine months ended September 30, 2019 includes $13.3 million and $23.1 million, respectively, of swaption premium income. Amount presented for the three and nine months ended September 30, 2018 includes $10.4 million and $29.4 million, respectively, of swaption premium income. See discussion below for information regarding an unrealized $94.9 million loss related to forward-starting interest rate swaps recorded.
(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 investment levels and the interest rates charged on borrowings.
(3) | Primarily reflects facility commitment fees charged in connection with our revolving credit facilities and amortization 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 2018 in connection with the redemption of junior subordinated notes.

Interest charged on debt principal outstanding, which is a key driver of interest expense, increased a net $22.8 million quarter-to-quarter primarily due to increased debt principal amounts outstanding during the third quarter of 2019, which accounted for a $24.1 million increase, partially offset by the effect of lower overall interest rates during the third quarter of 2019, which accounted for a $1.3 million decrease. Our weighted-average debt principal balance for the third quarter of 2019 was $27.93 billion compared to $26.08 billion for the third quarter of 2018. For the nine months ended September 30, 2019, interest charged on debt principal outstanding increased a net $47.9 million period-to-period primarily due to increased debt principal amounts outstanding during the nine months ended September 30, 2019, which accounted for a $53.8 million increase, partially offset by the effect of lower overall interest rates during the nine months ended September 30, 2019, which accounted for a $5.9 million decrease. Our weighted-average debt principal balance for the nine months ended September 30, 2019 was $27.29 billion compared to $25.76 billion for the nine months ended September 30, 2018. In general, our debt principal balances have increased over time due to the partial debt financing of our capital investments.
In July 2019, we sold options to be put into forward-starting swaps (referred to as “swaptions”) if the market rate of interest fell below the strike rate of the option upon expiration of the derivative instrument. The premium we realized upon sale of the swaptions is reflected as a $13.3 million reduction in interest expense for the three and nine months ended September 30, 2019, respectively.
Due to declining interest rates, the counterparties to the swaptions sold in July 2019 exercised their right to put us into ten forward-starting swaps on September 30, 2019 having an aggregate notional value of $1.0 billion. Forward-starting swaps hedge the risk of an increase in underlying benchmark interest rates during the period of time between the inception date of the swap agreement and the future date of debt issuance. Under the terms of the forward-starting swaps, we will pay to the counterparties (at the expected settlement dates of the instruments) amounts based on a 30-year fixed interest rate applied to the notional amount and receive from the counterparties an amount equal to a 30-year variable interest rate on the same notional amount. On September 30, 2019, the weighted-average fixed interest rate of the ten forward-starting swaps was 2.12%, which was 0.41% higher than the then applicable variable interest rate. As a result, we incurred an unrealized, mark-to-market loss at inception totaling $94.9 million that is reflected as an increase in interest expense for the three and nine months ended September 30, 2019. Prospectively, we will account for the forward-starting swaps as cash flow hedges, with any subsequent gains or losses on these derivative instruments reflected as a component of other comprehensive income and be amortized to earnings (through interest expense) over the 30-year period of the associated future debt issuance.

Table of Contents
Although we incurred a loss upon the exercise of these derivative instruments, we believe that the fixed interest rates that we will pay in connection with these forward-starting swaps are very favorable when compared to historical 30-year rates. Settlement of amounts accrued under the ten forward-starting swaps, including any gains or losses incurred from changes in interest rates between now and the contractual settlement dates, will occur at their respective expiration dates in September 2020 and April 2021.
Change in fair value of Liquidity Option Agreement
We recognize non-cash expense associated with accretion and changes in management estimates that affect our valuation of the Liquidity Option Agreement. For the three and nine months ended September 30, 2019, expense attributable to increases in the fair value of the Liquidity Option Agreement increased $20.2 million and $88.2 million, respectively, when compared to the same periods in 2018. Expense recognized during the three and nine months ending September 30, 2019 is primarily due to decreases in the applicable midstream industry weighted-average cost of capital, which is used as a discount factor in determining the present value of the liability, since June 30, 2019 and December 31, 2018, respectively. For additional information regarding the Liquidity Option Agreement, see Note 15 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
Upon our acquisition of the remaining 50% member interest in Delaware Basin Gas Processing LLC (“Delaware Processing”) in March 2018, our existing equity investment in Delaware Processing was remeasured to fair value resulting in the recognition of a non-cash gain of $39.4 million for the nine months ended September 30, 2018.
Income taxes
Provision for income taxes primarily reflects our state tax obligations under the Revised Texas Franchise Tax (the “Texas Margin Tax”). Our provision for income taxes for the three and nine months ended September 30, 2019 increased $4.4 million and $2.9 million, respectively, when compared to the same periods in 2018. Our partnership is not subject to U.S. federal income tax; however, our partners are individually responsible for paying federal income tax on their share of our taxable income.

Business Segment Highlights
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.
The following table presents gross operating margin by segment and non-GAAP total gross operating margin for the periods indicated (dollars in millions):

|  | For the Three Months Ended September 30, |  |  | For the Nine Months Ended September 30, |
|  | 2019 |  |  | 2018 |  |  | 2019 |  |  | 2018 |

Total gross operating margin (non-GAAP) |  | $ | 2,036.1 |  |  | $ | 2,123.3 |  |  | $ | 6,250.3 |  |  | $ | 5,187.6 |

(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. Our calculation of gross operating margin may or may not be comparable to similarly titled measures used by other companies.

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.

Gross operating margin from our Mont Belvieu propylene splitters increased $20.6 million quarter-to-quarter primarily due to higher propylene sales volumes. Gross operating margin from our PDH facility increased $17.2 million primarily due to higher propylene and associated by-product sales volumes. Propylene production volumes from our splitter units and PDH facility increased a combined 12 MBPD quarter-to-quarter.
Nine Months Ended September 30, 2019 Compared to Nine Months Ended September 30, 2018. Gross operating margin from propylene production and related marketing activities for the nine months ended September 30, 2019 increased $16.6 million when compared to the nine months ended September 30, 2018. Gross operating margin from our PDH facility, which commenced commercial operations in April 2018, increased $39.0 million period-to-period primarily due to higher propylene and associated by-product sales volumes. Plant production for the PDH facility, which includes by-products, increased 5 MBPD period-to-period. Gross operating margin from our Mont Belvieu propylene splitters decreased $23.9 million period-to-period primarily due to lower average propylene fractionation fees, which accounted for a $14.4 million decrease, and lower propylene production volumes, which accounted for an additional $8.0 million decrease. Propylene production volumes from our splitter units decreased 3 MBPD (net to our interest).
Butane isomerization and related DIB operations

Marine transportation and other
Third Quarter of 2019 Compared to Third Quarter of 2018. Gross operating margin from marine transportation for the third quarter of 2019 increased $5.8 million when compared to the third quarter of 2018 primarily due to higher barge fees quarter-to-quarter.
Nine Months Ended September 30, 2019 Compared to Nine Months Ended September 30, 2018. Gross operating margin from marine transportation for the nine months ended September 30, 2019 increased $16.0 million when compared to the nine months ended September 30, 2018 primarily due to higher barge fees period-to-period, which accounted for $23.5 million of the increase, partially offset by higher operating costs, which accounted for an $8.0 million decrease.
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, 2019, we had $6.21 billion of consolidated liquidity, which was comprised of $5.0 billion of available borrowing capacity under EPO’s revolving credit facilities and $1.21 billion of unrestricted cash on hand. On October 15, 2019, we repaid $800.0 million principal amount of EPO’s Senior Notes LL at their maturity using unrestricted cash.
We may issue equity and debt securities to assist us in meeting our future funding and liquidity requirements, including those related to capital investments. We have a universal shelf registration statement (the “2019 Shelf”) on file with the SEC which allows EPD and EPO (each on a standalone basis) to issue an unlimited amount of equity and debt securities, respectively. The 2019 Shelf replaced our prior universal shelf registration statement, which expired in May 2019.
Common Unit Repurchases under 2019 Buyback Program
In January 2019, the Board approved the 2019 Buyback Program, which authorized the partnership to repurchase up to $2.0 billion of EPD’s common units. For additional information regarding the 2019 Buyback Program, see “Significant Recent Developments” within this Part I, Item 2. No repurchases of common units were made under this program during the third quarter of 2019.
Consolidated Debt
The following table presents scheduled maturities of our consolidated debt obligations outstanding at September 30, 2019 for the years indicated (dollars in millions):

|  |  |  |  | Scheduled Maturities of Debt |

Amendment to Multi-Year Revolving Credit Agreement
In September 2019, EPO entered into an amendment (the “First Amendment”) to its revolving credit agreement dated September 13, 2017 (the “Multi-Year Revolving Credit Agreement”). The First Amendment reduces the borrowing capacity under the Multi-Year Revolving Credit Agreement from $4.0 billion to $3.5 billion (which may be increased by up to $500 million to $4.0 billion at EPO’s election provided certain conditions are met) and extends the maturity date to September 10, 2024, although the maturity date may be extended further at EPO’s request by up to two years, with the consent of required lenders as set forth under the credit agreement. Borrowings under this revolving credit agreement may be used for working capital, capital expenditures, acquisitions and general company purposes. There are currently no principal amounts outstanding under this revolving credit agreement.
Renewal of 364-Day Revolving Credit Agreement
In September 2019, 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 2020. Under the terms of the new 364-Day Revolving Credit Agreement, EPO may borrow up to $1.5 billion (which may be increased by up to $200 million to $1.7 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 non-revolving term loans for a period of one additional year, payable in September 2021. Borrowings under this revolving credit agreement may be used for working capital, capital expenditures, acquisitions and general company purposes. There are currently no principal amounts outstanding under this revolving credit agreement.
Issuance of $2.5 Billion of Senior Notes in July 2019
In July 2019, EPO issued $2.5 billion aggregate principal amount of senior notes comprised of $1.25 billion principal amount of senior notes due July 2029 (“Senior Notes YY”) and $1.25 billion principal amount of senior notes due January 2050 (“Senior Notes ZZ”). Net proceeds from this offering were used by EPO for the repayment of debt and for general company purposes, including for growth capital expenditures.
Senior Notes YY were issued at 99.955% of their principal amount and have a fixed interest rate of 3.125% per year. Senior Notes ZZ were issued at 99.792% of their principal amount and have a fixed interest rate of 4.20% per year.
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 8, 2019, 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 under DRIP and EUPP
EPD issued and delivered a combined 2,897,990 common units in the six months ended June 30, 2019 in connection with its distribution reinvestment plan (“DRIP”) and employee unit purchase plan (“EUPP”). In total, the net cash proceeds EPD received from these issuances was $82.2 million.
69

Table of Contents
In July 2019, EPD announced that, beginning with the quarterly distribution payment paid in August 2019, it would use common units purchased on the open market, rather than issuing new common units, to satisfy its delivery obligations under the DRIP and EUPP. This election is subject to change in future quarters depending on the partnership’s need for equity capital. In August 2019, a total of 1,410,020 common units were purchased on the open market and delivered to participants in connection with the DRIP and EUPP. Other than amounts tied to the plan discount available to all participants in the EUPP, the funds used to effect these purchases were sourced entirely from the DRIP and EUPP participants. No other partnership funds were used to satisfy these obligations. We plan to use open market purchases to satisfy DRIP and EUPP reinvestments in connection with the distribution expected to be paid on November 12, 2019.
For additional information regarding EPD’s issuance of common units under the DRIP and EUPP registration statements, see Note 8 of the Notes to Unaudited Condensed Consolidated Financial Statements included under Part I, Item 1 of this quarterly report.
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.

|  | For the Nine Months Ended September 30, |
|  | 2019 |  |  | 2018 |
Net cash flows provided by operating activities |  | $ | 4,826.2 |  |  | $ | 4,275.3 |
Cash used in investing activities |  |  | 3,372.8 |  |  |  | 3,182.8 |
Cash used in financing activities |  |  | 655.7 |  |  |  | 883.7 |

Net cash flows provided by operating activities are largely dependent on earnings from our consolidated business activities. Changes in energy commodity prices may impact the demand for natural gas, NGLs, crude oil, petrochemical and refined products, which could impact sales of our products and the demand for our midstream services. Changes in demand for our products and services 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 activities and long-term take-or-pay agreements. For a more complete discussion of these and other risk factors pertinent to our business, see Part I, Item 1A of the 2018 Form 10-K.
The following information highlights primary drivers of the 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, 2019 increased a net $550.9 million when compared to the nine months ended September 30, 2018 primarily due to:

| • | a $612.5 million period-to-period increase resulting from higher year-to-date partnership earnings in 2019 when compared to the same nine month period in 2018 (determined by adjusting our $628.4 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); and

| • | an $85.5 million period-to-period increase in cash distributions received on earnings from unconsolidated affiliates primarily due to investments in crude oil pipeline businesses; partially offset by

| • | a $147.1 million period-to-period decrease primarily due to the timing of cash receipts and payments related to operations.

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

Investing activities
Cash used in investing activities for the nine months ended September 30, 2019 increased a net $190.0 million when compared to the nine months ended September 30, 2018 primarily due to:

| • | a $297.9 million period-to-period increase in expenditures for consolidated property, plant and equipment (see “Capital Investments” within this Part I, Item 2 for additional information); partially offset by

| • | a $150.6 million decrease period-to-period in net cash used for business combinations. In March 2018, we paid $150.6 million to acquire a 50% equity interest in Delaware Processing.

Financing activities
Cash used in financing activities for the nine months ended September 30, 2019 decreased $228.0 million when compared to the nine months ended September 30, 2018 primarily due to:

| • | a net $430.1 million period-to-period increase in net cash inflows from debt. In the nine months ended September 30, 2019, we issued $2.5 billion aggregate principal amount of senior notes, partially offset by the repayment or repurchase of $724.2 million principal amount of senior and junior subordinated notes. In the nine months ended September 30, 2018, we issued $2.7 billion aggregate principal amount of senior notes and junior subordinated notes and $950.2 million of short-term notes under EPO’s commercial paper program, partially offset by the repayment of $2.3 billion in principal amount of senior and junior subordinated notes; and

| • | a $368.8 million period-to-period increase in cash contributions from noncontrolling interests. In July 2019, Altus acquired a noncontrolling 33% equity interest in our consolidated subsidiary that owns the Shin Oak pipeline for an initial payment of $440.7 million. In June 2019, an affiliate of American Midstream, LP acquired a noncontrolling 25% equity interest in our consolidated subsidiary that owns the Pascagoula natural gas processing plant for $36.0 million in cash. In June 2018, Western acquired a noncontrolling 20% equity interest in our consolidated subsidiary that owns the Midland-to-ECHO 1 pipeline for $189.6 million in cash. In addition, cash contributions from noncontrolling interests in connection with the construction of our ethylene export facility increased $47.0 million period-to-period; partially offset by

| • | a $367.2 million period-to-period decrease in net cash proceeds from the issuance of common units in connection with our DRIP and EUPP. As noted previously, EPD announced in July 2019 that, beginning with the quarterly distribution payment paid in August 2019, it would use common units purchased on the open market, rather than issuing new common units, to satisfy its delivery obligations under the DRIP and EUPP;

| • | an $88.2 million period-to-period increase in cash distributions paid to limited partners primarily due to an increase in the quarterly cash distribution rate per unit; and

| • | the use of $81.1 million in the nine months ended September 30, 2019 to acquire 2,909,128 common units under the 2019 Buyback Program.

Non-GAAP Cash Flow Measures
Distributable Cash Flow
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 those for capital expenditures, debt service, working capital, operating expenses, common unit repurchases, commitments and contingencies and other 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 (“DCF”), which is a non-GAAP cash flow measure. DCF is an important 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 our declared quarterly cash distributions. DCF is also a
71

Table of Contents
quantitative standard used by the investment community with respect to publicly traded partnerships since 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 DCF we generate to the cash distributions we expect to pay our partners. Using this metric, management computes our distribution coverage ratio. Our calculation of DCF may or may not be comparable to similarly titled measures used by other companies.
Based on the level of available cash each quarter, 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 DCF 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.
The following table summarizes our calculation of DCF for the periods indicated (dollars in millions):

Free Cash Flow
Free Cash Flow (“FCF”), a non-GAAP financial measure, is a traditional cash flow metric that is widely used by a variety of investors and other participants in the financial community, as opposed to DCF, which is a cash flow measure primarily used by investors and others in evaluating master limited partnerships. In general, FCF is a measure of how much cash flow a business generates during a specified time period after accounting for all capital investments, including expenditures for growth and sustaining capital projects. By comparison, only sustaining capital expenditures are reflected in DCF.
We believe that FCF is important to traditional investors since it reflects the amount of cash available for reducing debt, investing in additional capital projects, paying distributions, common unit repurchases and similar matters. Since business partners fund certain capital projects of our consolidated subsidiaries, our determination of FCF reflects the amount of cash contributed from and distributed to noncontrolling interests. Our calculation of FCF may or may not be comparable to similarly titled measures used by other companies.
Our use of FCF 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.
FCF fluctuates based on our earnings, the level of investing activities we undertake each period, and the timing of operating cash receipts and payments. In addition to providing the quarterly amounts presented below, we also provide a calculation of aggregate FCF over the twelve months ended September 30, 2019 in order to measure FCF over a longer term. The following table summarizes our calculation of FCF for the periods indicated (dollars in millions):

Capital Investments
We currently have $9.1 billion of growth capital projects scheduled to be completed by the end of 2023 including the following major projects:

• | our iBDH facility (fourth quarter of 2019),

• | the Shin Oak NGL pipeline (full service capacity expected to be available in fourth quarter of 2019),

• | our ethylene export terminal and related infrastructure (fourth quarter of 2019 through the fourth quarter of 2020),

• | two new NGL fractionators in Chambers County, Texas (“Frac X” in the fourth quarter of 2019 and “Frac XI” in the first half of 2020),

• | our Mentone cryogenic natural gas processing plant and related infrastructure (first quarter of 2020),

• | increase in LPG loading capacity at EHT (fourth quarter of 2020),

• | expansion projects involving our crude oil system between the Permian Basin and our ECHO terminal (third quarter of 2020),

• | our Midland-to-ECHO 3 and 4 pipelines (third quarter of 2020 and first half of 2021, respectively),

• | expansion of our PGP export capabilities and an eighth deep-water ship dock at EHT for loading crude oil (both projects scheduled for fourth quarter of 2020),

• | expansion and extension of Acadian Gas System (Gillis Lateral and related projects) (mid-2021),

• | expansion of our ATEX pipeline (fiscal 2022), and

• | construction of our PDH 2 facility (first half of 2023).

Based on information currently available, we expect our total capital investments for 2019 to approximate a net $4.3 billion, which reflects growth capital expenditures of $4.5 billion, $350 million for sustaining capital expenditures and $0.6 billion of cash contributions from noncontrolling interests. We currently expect growth capital investments to approximate $3.0 billion to $4.0 billion in 2020.
Our forecast of capital investments for 2019 and 2020 is based on 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 investments due to factors beyond our control, such as adverse economic conditions, weather-related issues and changes in supplier prices. Furthermore, our forecast of capital investments may change due to decisions made by management at a later date, which may include unforeseen acquisition opportunities.
Our success in raising capital, including partnering with other companies to share project 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 investments noted above, we may adjust the timing and amounts of projected expenditures in response to changes in capital market conditions.

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

|  | For the Nine Months Ended September 30, |
|  | 2019 |  |  | 2018 |
Capital investments for property, plant and equipment: (1) |  |  |  |  |  |
Growth capital projects (2) |  | $ | 3,072.4 |  |  | $ | 2,782.7 |
Sustaining capital projects (3) |  |  | 229.7 |  |  |  | 221.5 |
Total |  | $ | 3,302.1 |  |  | $ | 3,004.2 |
Cash used for business combinations, net |  | $ | – |  |  | $ | 150.6 |
Investments in unconsolidated affiliates |  | $ | 100.1 |  |  | $ | 95.1 |

(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.

Fluctuations in our investments in growth capital projects and investments in unconsolidated affiliates are explained in large part by increases or decreases in expenditures for major expansion projects. Our most significant growth capital investments for the nine months ended September 30, 2019 involve projects at our Mont Belvieu complex, crude oil pipelines in Texas and expansion projects involving our Gulf Coast export terminals. Fluctuations in investments in 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, 2019 with Nine Months Ended September 30, 2018
Investments in growth capital projects at our Mont Belvieu complex increased $403.1 million period-to-period primarily due to construction activities surrounding Frac X and Frac XI, which accounted for a combined $425.5 million increase, our iBDH facility, which accounted for a $68.9 million increase, and expansion projects involving our DIBs, which accounted for an additional $62.9 million increase, partially offset by lower expenditures attributable to our PDH facility and ninth Mont Belvieu-area NGL fractionator (“Frac IX”), which accounted for a combined $182.8 million decrease. Our PDH facility and Frac IX were both placed into service during the second quarter of 2018.
Investments in growth capital projects for ethylene-related pipelines, storage facilities and export assets increased $199.8 million period-to-period.
Investments in growth capital projects in support of Permian Basin production decreased $315.2 million period-to-period primarily due to lower expenditures at our Orla natural gas processing facility, which accounted for a $314.3 million decrease, and for our Shin Oak NGL Pipeline, which accounted for an additional $235.5 million decrease, partially offset by increased expenditures at our Mentone natural gas processing plant, which accounted for a $194.4 million increase. The third processing train at our Orla natural gas processing facility was placed into service in July 2019.
Net cash used for business combinations during the nine months ended September 30, 2018 reflects our acquisition of the remaining 50% member interest in Delaware Processing in March 2018.

Critical Accounting Policies and Estimates
A discussion of our critical accounting policies and estimates is included in our 2018 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
The principal amount of our consolidated debt obligations were $28.2 billion at September 30, 2019 compared to $26.42 billion at December 31, 2018. 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 information regarding our consolidated debt obligations.
Since December 31, 2018, we have entered into additional long-term purchase commitments for NGLs with third-party suppliers. On a combined basis, these new agreements increased our estimated long-term purchase obligations by $3.6 billion, with $1.3 billion committed over the next five years and $2.3 billion thereafter. At September 30, 2019, our estimated long-term purchase obligations totaled $12.7 billion after reflecting the agreements added during the first nine months of 2019 and those commitments that expired during the year. At December 31, 2018, our estimated long-term purchase obligations totaled $10.8 billion.
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.

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 13 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, 2019 (volume measures as noted):

| Volume (1) | Accounting
Derivative Purpose | Current (2) | Long-Term (2) | Treatment

Sensitivity Analysis
The following tables show the effect of hypothetical price movements on the estimated fair values of our principal commodity derivative instrument portfolios at the dates indicated (dollars in millions).
The fair value information presented in the sensitivity analysis tables excludes the impact of applying Chicago Mercantile Exchange (“CME”) Rule 814, 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.

Interest Rate Hedging Activities
We may utilize interest rate swaps, forward-starting swaps, options to enter into forward-starting swaps (“swaptions”), 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.
Sensitivity Analysis
With respect to the tabular data below, the portfolio’s estimated economic value at a given date is based on a number of factors, including the number and types of derivatives outstanding at that date, the notional value of the swaps and
associated interest rates.
At September 30, 2019, our interest rate hedging portfolio consisted of 12 forward-starting swaps, which hedge the expected underlying benchmark interest rates related to future issuances of debt. The following table summarizes our portfolio of these swaps at September 30, 2019 (dollars in millions).

Hedged Transaction | Number and Type of Derivatives Outstanding | Notional Amount | Expected Settlement Date | Weighted-Average Fixed Rate Locked | Accounting Treatment
Future long-term debt offering | 1 forward-starting swap (1) | $75.0 | 9/2020 | 2.39% | Cash flow hedge
Future long-term debt offering | 1 forward-starting swap (1) | $75.0 | 4/2021 | 2.41% | Cash flow hedge
Future long-term debt offering | 5 forward-starting swaps (2) | $500.0 | 9/2020 | 2.12% | Cash flow hedge
Future long-term debt offering | 5 forward-starting swaps (2) | $500.0 | 4/2021 | 2.13% | Cash flow hedge

(1) | These swaps were entered into in May 2019.
(2) | These swaps were entered into in September 2019 as a result of a swaption exercise. See “Interest Rate Hedging Activities” under Note 13 of the Unaudited Condensed Consolidated Financial Statements included under Part I, Item 1 of this quarterly report for additional information regarding the swaption exercise and related loss at inception.

The following table shows the effect of hypothetical price movements (a sensitivity analysis) on the estimated economic value of our forward-starting swap portfolio at the dates indicated (dollars in millions):

|  | Forward-Starting Swap Portfolio Fair Value at |
Scenario | Resulting Classification | December 31, 2018 |  | September 30, 2019 |  | November 7, 2019 |
Fair value assuming no change in underlying interest rates | Asset (Liability) |  | $ | – |  |  | $ | (118.6 | ) |  | $ | (37.1 | )
Fair value assuming 10% increase in underlying interest rates | Asset (Liability) |  |  | – |  |  |  | (71.7 | ) |  |  | 5.0 |
Fair value assuming 10% decrease in underlying interest rates | Asset (Liability) |  |  | – |  |  |  | (168.0 | ) |  |  | (79.2 | )

The $81.5 million change in the fair value of this portfolio from September 30, 2019 to November 7, 2019 was due to an increase in the underlying 30-year variable interest rates relative to the fixed interest rates stated in the associated swap agreements.

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 2019, 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.
In June 2019, we received a Notice of Violation from the U.S. Environmental Protection Agency in connection with regulatory requirements applicable to facilities that we operate in Baton Rouge, Louisiana. The eventual resolution of this matter may result in monetary sanctions in excess of $0.1 million; however, we do not expect such expenditures to be material to our consolidated financial statements.
For additional information regarding our litigation matters, see “Litigation” under Note 15 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.
