Bachmann, who is also a director and Vice Chairman of the Board of Enterprise GP; and (iii) Dr. Ralph S. Cunningham, who is also an advisory director of Enterprise GP. Ms. Duncan Williams and Mr. Bachmann also currently serve as managers of Dan Duncan LLC along with W.

Note 1. Partnership Organization and Basis of Presentation
We are a publicly traded Delaware limited partnership, the common units of which are listed on the New York Stock Exchange (“NYSE”) under the ticker symbol “EPD.” We were formed in April 1998 to own and operate certain natural gas liquids (“NGLs”) related businesses of EPCO and are a leading North American provider of midstream energy services to producers and consumers of natural gas, NGLs, crude oil, petrochemicals and refined products.
We conduct substantially all of our business through EPO and are owned 100% by our limited partners from an economic perspective. Enterprise GP manages our partnership and owns a non-economic general partner interest in us. We, Enterprise GP, EPCO and Dan Duncan LLC are affiliates under the collective common control of the DD LLC Trustees and the EPCO Trustees. Like many publicly traded partnerships, we have no employees. All of our management, administrative and operating functions are performed by employees of EPCO pursuant to an administrative services agreement (the “ASA”) or by other service providers. See Note 14 for information regarding related party matters.
Our results of operations for the three months ended March 31, 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”).

These Unaudited Condensed Consolidated Financial Statements and Notes thereto should be read in conjunction with the Audited Consolidated Financial Statements and Notes thereto included in our annual report on Form 10-K for the year ended December 31, 2018 (the “2018 Form 10-K”) filed with the SEC on March 1, 2019.
Note 2. Summary of Significant Accounting Policies
Apart from those matters noted below, there have been no changes in our significant accounting policies since those reported under Note 2 of the 2018 Form 10-K.
Cash, Cash Equivalents and Restricted Cash
The following table provides a reconciliation of cash and cash equivalents, and restricted cash reported within the Unaudited Condensed Consolidated Balance Sheets that sum to the total of the amounts shown in the Unaudited Condensed Statements of Consolidated Cash Flows.

|  | March 31, 2019 |  |  | December 31, 2018 |
Cash and cash equivalents |  | $ | 99.3 |  |  | $ | 344.8 |
Restricted cash |  |  | 8.2 |  |  |  | 65.3 |
Total cash, cash equivalents and restricted cash shown in the Unaudited Condensed Statements of Consolidated Cash Flows |  | $ | 107.5 |  |  | $ | 410.1 |

Restricted cash represents amounts held in segregated bank accounts by our clearing brokers as margin in support of our commodity derivative instruments portfolio and related physical purchases and sales of natural gas, NGLs, crude oil and refined products. Additional cash may be restricted to maintain our commodity derivative instruments portfolio as prices fluctuate or margin requirements change. The balance of restricted cash at March 31, 2019 consisted of initial margin requirements of $34.3 million partially offset by positive variation margin requirements of $26.1 million. The initial margin requirements will be returned to us as the related derivative instruments are settled. 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.

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

|  | March 31, 2019 |  |  | December 31, 2018 |
NGLs |  | $ | 849.7 |  |  | $ | 647.7 |
Petrochemicals and refined products |  |  | 287.6 |  |  |  | 264.7 |
Crude oil |  |  | 533.8 |  |  |  | 593.4 |
Natural gas |  |  | 9.4 |  |  |  | 16.3 |
Total |  | $ | 1,680.5 |  |  | $ | 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 March 31, |
|  | 2019 |  |  | 2018 |
Cost of sales (1) |  | $ | 5,835.6 |  |  | $ | 7,140.4 |
Lower of cost or net realizable value adjustments within cost of sales |  |  | 5.4 |  |  |  | 1.9 |
(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. |

Property, plant and equipment, net |  |  |  |  |  | $ | 39,347.5 |  |  | $ | 38,737.6 |
(1) Plants, pipelines and facilities include processing plants; NGL, natural gas, crude oil and petrochemical and refined products pipelines; terminal loading and unloading facilities; buildings; office furniture and equipment; laboratory and shop equipment and related assets. (2) Underground and other storage facilities include underground product storage caverns; above ground storage tanks; water wells and related assets. (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 March 31, |
|  | 2019 |  |  | 2018 |
Depreciation expense (1) |  | $ | 380.6 |  |  | $ | 331.8 |
Capitalized interest (2) |  |  | 36.2 |  |  |  | 58.2 |
(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 March 31, 2019 and December 31, 2018 includes $72.1 million and $72.5 million, respectively, of asset retirement costs capitalized as an increase in the associated long-lived asset. The following table presents information regarding our asset retirement obligations, or AROs, since January 1, 2019:

ARO liability balance, December 31, 2018 |  | $ | 126.3 |

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
The net cash proceeds we received from the issuance of common units during the three months ended March 31, 2019 were used to temporarily reduce amounts outstanding under EPO’s commercial paper program and for general company purposes, including for growth capital expenditures.
We may issue additional equity and debt securities to assist us in meeting our future liquidity requirements, including those related to capital investments. We have a universal shelf registration statement (the “2019 Shelf”) on file with the SEC which allows Enterprise Products Partners L.P. and EPO (each on a standalone basis) to issue an unlimited amount of equity and debt securities, respectively. The 2019 Shelf replaced our prior universal shelf registration statement, which was set to expire in May 2019.
We also have a registration statement on file with the SEC covering the issuance of up to $2.54 billion of our common units in amounts, at prices and on terms to be determined by market conditions and other factors at the time of such offerings in connection with our at-the-market (“ATM”) program. During the three months ended March 31, 2019 and 2018, we did not issue any common units under the ATM program. After taking into account the aggregate sales price of common units sold under the ATM program through March 31, 2019, we have the capacity to issue additional common units under the ATM program up to an aggregate sales price of $2.54 billion.
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 the partnership with an additional method to return capital to investors. The 2019 Buyback Program authorizes the partnership 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) our unit price and implied cash flow yield and (iv) maintaining targeted financial leverage with a debt-to-normalized adjusted EBITDA, or earnings before interest, taxes, depreciation and amortization, ratio in the 3.5 times area. No time limit has been set for completion of the program, and it may be suspended or discontinued at any time.
We repurchased 1,852,392 common units under the 2019 Buyback Program during the three months ended March 31, 2019 for a total purchase price of $51.6 million, excluding commissions and fees. The repurchased units were cancelled immediately upon acquisition. At March 31, 2019, the remaining available capacity under the 2019 Buyback Program was $1.95 billion.
Common units issued in connection with DRIP and EUPP
We have registration statements on file with the SEC in connection with our distribution reinvestment plan (“DRIP”) and employee unit purchase plan (“EUPP”). We issued a total of 1,368,145 common units under the DRIP during the three months ended March 31, 2019, which generated net cash proceeds of $38.5 million. During the three months ended March 31, 2018, we issued 6,509,653 common units under our DRIP, which generated net cash proceeds of $173.3 million. After taking into account the number of common units issued under the DRIP through March 31, 2019, we have the capacity to issue an additional 60,032,214 common units under this plan.
We issued 148,634 common units under the EUPP during the three months ended March 31, 2019, which generated net cash proceeds of $4.2 million. During the three months ended March 31, 2018, we issued 132,633 common units under our EUPP, which generated net cash proceeds of $3.7 million. After taking into account the number of common units issued under the EUPP through March 31, 2019, we may issue an additional 5,067,007 common units under this plan.
Common Units Issued in Connection With Employee Compensation
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 with respect 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 Enterprise common units under EPCO’s 2008 Enterprise Products Long-Term Incentive Plan (Third Amendment and Restatement) (“2008 Plan”). In February 2019, we 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.

Cash Distributions
In January 2019, management announced its 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 April 8, 2019, we announced that the Board declared a cash distribution of $0.4375 per common unit with respect to the first quarter of 2019, which represents a 2.3% increase over the $0.4275 per common unit declared and paid with respect to the first quarter of 2018. The distribution with respect to the first quarter of 2019 will be paid on May 13, 2019 to unitholders of record as of the close of business on April 30, 2019.

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.
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.

|  | 2019 |  |  | 2018 |
Operating income |  | $ | 1,626.2 |  |  | $ | 1,138.5 |

Depreciation, amortization and accretion expense in operating costs and expenses |  |  | 450.9 |  |  |  | 394.3 |
Asset impairment and related charges in operating costs and expenses |  |  | 4.8 |  |  |  | 0.9 |

Non-refundable payments received from shippers attributable to make-up rights (1) |  |  | 2.2 |  |  |  | 2.7 |
Subsequent recognition of revenues attributable to make-up rights (2) |  |  | (7.5 | ) |  |  | (14.2 | )
Total segment gross operating margin |  | $ | 2,128.4 |  |  | $ | 1,574.7 |
(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:

|  | For the Three Months Ended March 31, |

(1) Represents the cost of operating our plants, pipelines and other fixed assets excluding: depreciation, amortization and accretion charges; asset impairment and related charges; and net losses (or gains) attributable to asset sales. |

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

Diluted earnings per unit |  | $ | 0.57 |  |  | $ | 0.41 |
(1) Each phantom unit award includes a distribution equivalent right (“DERs”), 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 our common unitholders. 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 March 31, |
|  | 2019 |  |  | 2018 |
Equity-classified awards: |  |  |  |  |  |
Phantom unit awards |  | $ | 29.4 |  |  | $ | 24.6 |
Profits interest awards |  |  | 2.6 |  |  |  | 1.6 |
Liability-classified awards |  |  | -- |  |  |  | 0.1 |
Total |  | $ | 32.0 |  |  | $ | 26.3 |

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 our common units (at no cost to the recipient apart from fulfilling service and other conditions) once a defined vesting period expires, subject to customary forfeiture provisions. 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) |  |  | 6,831,820 |  |  | $ | 27.75 |
Vested |  |  | (3,398,583 | ) |  | $ | 27.59 |
Forfeited |  |  | (77,627 | ) |  | $ | 27.09 |
Phantom unit awards at March 31, 2019 |  |  | 13,688,887 |  |  | $ | 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 $189.6 million based on a grant date market price of our common units of $27.75 per unit. An estimated annual forfeiture rate of 3.0% was applied to these awards. |

Each phantom unit award includes a distribution equivalent right (“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 our 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 March 31, |
|  | 2019 |  |  | 2018 |
Cash payments made in connection with DERs |  | $ | 4.5 |  |  | $ | 3.9 |
Total intrinsic value of phantom unit awards that vested during period |  |  | 97.0 |  |  |  | 82.0 |

The unrecognized compensation cost associated with phantom unit awards was $247.6 million at March 31, 2019, of which our share of the cost is currently estimated to be $213.6 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 2.4 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 March 31, 2019, our share of the total unrecognized compensation cost related to the Employee Partnerships was $33.0 million, which we expect to recognize over a weighted-average period of 3.7 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 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.
We sold swaptions related to our interest rate hedging activities that resulted in the recognition of $9.8 million of cash gains that were reflected as a reduction in interest expense for the first quarter of 2019.

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 March 31, 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 March 31, 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.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
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.

Total |  | $ | 3.9 |  |  | $ | 3.0 |  |  |  |

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 March 31, 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:

|  |  | For the Three Months Ended March 31, |
| Location |  | 2019 |  |  | 2018 |
Financial liability balance, net, December 31, 2018 |  |  | $ | (395.9 | ) |  | $ | (332.7 | )

(1) There were unrealized gains of $3.0 million and unrealized losses of $1.7 million included in these amounts for the three months ended March 31, 2019 and 2018, respectively. |

Nonrecurring Fair Value Measurements
Non-cash asset impairment charges for the three months ended March 31, 2019 were $4.8 million compared to $0.9 million for the three months ended March 31, 2018. Charges for the first quarter of 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 $26.82 billion and $25.97 billion at March 31, 2019 and December 31, 2018, respectively. The aggregate carrying value of these debt obligations was $25.45 billion and $26.15 billion at March 31, 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.
Note 14. Related Party Transactions
The following table summarizes our related party transactions for the periods indicated:

|  | For the Three Months Ended March 31, |

We believe that the terms and provisions of our related party agreements are fair to us; however, such agreements and transactions may not be as favorable to us as we could have obtained from unaffiliated third parties.
Relationship with EPCO and Affiliates
We have an extensive and ongoing relationship with EPCO and its privately held affiliates (including Enterprise GP, our general partner), which are not a part of our consolidated group of companies.
At March 31, 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
697,786,410 | 31.9%

Table of Contents
ENTERPRISE PRODUCTS PARTNERS L.P.
NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
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 March 31, 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 our common units.
We and Enterprise GP are both separate legal entities apart from each other and apart from EPCO and its other affiliates, with assets and liabilities that are also separate from those of EPCO and its other affiliates. EPCO and its privately held affiliates depend on the cash distributions they receive from us and other investments to fund their other activities and to meet their debt obligations. During the three months ended March 31, 2019 and 2018, we paid EPCO and its privately held affiliates cash distributions totaling $296.0 million and $286.9 million, respectively.
From time-to-time, EPCO and its privately held affiliates elect to purchase additional common units under our DRIP and ATM program. During the three months ended March 31, 2019, privately held affiliates of EPCO reinvested $7 million through the DRIP. See Note 8 for additional information regarding our DRIP.
We have no employees. All of our operating functions and general and administrative support services are provided by employees of EPCO pursuant to the ASA or by other service providers. The following table presents our related party costs and expenses attributable to the ASA with EPCO for the periods indicated:

|  | For the Three Months Ended March 31, |
|  | 2019 |  |  | 2018 |
Operating costs and expenses |  | $ | 239.1 |  |  | $ | 223.0 |

Total costs and expenses |  | $ | 268.4 |  |  | $ | 252.2 |

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.
At March 31, 2019 and December 31, 2018, our accruals for litigation contingencies were $0.5 million and $0.5 million, respectively, 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.

ENTERPRISE PRODUCTS PARTNERS L.P.
NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
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 July18, 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 have filed their respective submittals.
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 $27.12 billion and $26.42 billion at March 31, 2019 and December 31, 2018, respectively. See Note 7 for additional information regarding our scheduled future maturities of debt principal.

Total |  | $ | 236.3 |  |  | $ | 238.0 |  |  |  |  |  |
(1) ROU asset amounts are a component of “Other assets” on our consolidated balance sheet. (2) At March 31, 2019, lease liabilities of $38.2 million and $199.8 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 three months ended March 31, 2019:

Long-term operating leases: |  |  |
Fixed lease expense |  | $ | 13.4 |
Variable lease expense |  |  | 1.8 |
Subtotal operating lease expense |  |  | 15.2 |
Short-term lease expense |  |  | 11.8 |
Total operating lease expense |  | $ | 27.0 |

In total, operating lease expense was $27.0 million and $25.6 million for the three months ended March 31, 2019 and 2018, 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 months ended March 31, 2019 was $4.8 million, which represented less than 1% of our consolidated revenues. We do not have any sales-type leases.
Our operating lease commitments at March 31, 2019 did not differ materially from those reported in our 2018 Form 10-K.
Purchase Obligations
During the first quarter of 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 $3.2 billion, with $1.1 billion committed over the next five years and $2.1 billion thereafter. At March 31, 2019, our estimated long-term purchase obligations totaled $13.5 billion after reflecting the agreements added in the first quarter of 2019 and those commitments that expired during the quarter. 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 Enterprise 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 Consolidated Balance Sheet, was $447.8 million and $390.0 million at March 31, 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 Statements of Consolidated Operations. Results for the three months ended March 31, 2019 and 2018 include $57.8 million and $7.5 million, respectively, of aggregate non-cash expense attributable to accretion and changes in management estimates regarding inputs to the valuation model. Expense recognized for the first quarter of 2019 is primarily due to an approximate 1% decrease in the 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 changed since those reported under Note 17 of the 2018 Form 10-K.
Our valuation estimate incorporates probability-weighted scenarios reflecting the likelihood that M&B may elect to divest a portion of the Enterprise common units held by OTA prior to exercise of the option (see Note 8 for information regarding the Registration Rights Agreement granted to OTA). At March 31, 2019, based on these scenarios, we expect that OTA would own approximately 96% of the 54,807,352 Enterprise common units it received in Step 1 when the option period begins in February 2020. If our valuation estimate assumed that OTA owned all of the Enterprise common units it received in Step 1 at the time of exercise (and all other inputs remained the same), the estimated fair value of the Liquidity Option liability at March 31, 2019 would increase by $20.1 million.

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 49,200 miles of pipelines; 260 MMBbls of storage capacity for NGLs, crude oil, petrochemicals and refined products; and 14 Bcf of natural gas storage capacity.
We conduct substantially all of our business through EPO and are owned 100% by our limited partners from an economic perspective. Enterprise GP manages our partnership and owns a non-economic general partner interest in us. We, Enterprise GP, EPCO and Dan Duncan LLC are affiliates under the collective common control of the DD LLC Trustees and the EPCO Trustees. Like many publicly traded partnerships, we have no employees. All of our management, administrative and operating functions are performed by employees of EPCO pursuant to an administrative services agreement (the “ASA”) or by other service providers.
Our operations are reported under four business segments: (i) NGL Pipelines & Services, (ii) Crude Oil Pipelines & Services, (iii) Natural Gas Pipelines & Services, and (iv) Petrochemical & Refined Products Services. Our business segments are generally organized and managed according to the types of services rendered (or technologies employed) and products produced and/or sold.
Each of our business segments benefits from the supporting role of our related marketing activities. The main purpose of our marketing activities is to support the utilization and expansion of assets across our midstream energy asset network by increasing the volumes handled by such assets, which results in additional fee-based earnings for each business segment. In performing these support roles, our marketing activities also seek to participate in supply and demand opportunities as a supplemental source of gross operating margin, a non-generally accepted accounting principle (“non-GAAP”) financial measure, for the partnership. The financial results of our marketing efforts fluctuate due to changes in volumes handled and overall market conditions, which are influenced by current and forward market prices for the products bought and sold.

Significant Recent Developments
Enterprise Begins Full Service on Midland-to-ECHO 2 Pipeline System
In April 2019, our Midland-to-ECHO 2 Pipeline System, which provides us with approximately 200 MBPD of incremental crude oil transportation capacity from the Permian Basin to markets in the Houston area, was placed into full service. The pipeline had been in limited commercial service since February 2019. The Midland-to-ECHO 2 Pipeline System originates at our Midland terminal and extends 440 miles to our Sealy storage terminal, with volumes arriving at Sealy transported to our ECHO terminal using the Rancho II pipeline, which is a component of our South Texas Crude Oil Pipeline System. We own and operate the Midland-to-ECHO 2 Pipeline System.
We converted a portion of our Seminole NGL Pipeline system from NGL service to crude oil service to create the Midland-to-Sealy segment of the Midland-to-ECHO 2 Pipeline System. The conversion project was supported by a 10.75-year transportation contract with firm demand fees. We have the ability to convert this pipeline back to NGL service should market and physical takeaway conditions warrant.
Enterprise Begins Limited Service on the Shin Oak NGL Pipeline
In February 2019, the 24-inch diameter mainline segment of the 658-mile Shin Oak NGL Pipeline from Orla, Texas to Mont Belvieu was placed into limited commercial service with an initial transportation capacity of 250 MBPD. Completion of the related 20-inch diameter Waha lateral is scheduled for the second quarter of 2019. Supported by long-term customer commitments, the Shin Oak NGL Pipeline will ultimately provide up to 550 MBPD of transportation capacity, which is expected to be available 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 the partnership with an additional method to return capital to investors. The 2019 Buyback Program authorizes the partnership 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) our unit price and implied cash flow yield and (iv) maintaining targeted financial leverage with a debt-to-normalized adjusted EBITDA, or earnings before interest, taxes, depreciation and amortization, ratio in the 3.5 times area. No time limit has been set for completion of the program, and it may be suspended or discontinued at any time.
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 April 8, 2019, we announced that the Board declared a cash distribution of $0.4375 per common unit with respect to the first quarter of 2019. This distribution will be paid on May 13, 2019 to unitholders of record as of the close of business on April 30, 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 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 30% ethane, 35% propane, 12% normal butane, 8% isobutane and 15% natural gasoline. The value of an equivalent amount of energy in natural gas to one gallon of NGLs is assumed to be 8.9% 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. Energy commodity prices fluctuate for a variety of reasons, including supply and demand imbalances and geopolitical tensions. The weighted-average indicative market price for NGLs was $0.66 per gallon in the first quarter of 2019 versus $0.77 per gallon during the first quarter of 2018.

Table of Contents
An increase in our consolidated marketing revenues due to higher energy commodity sales prices may not result in an increase in gross operating margin or cash available for distribution, since our consolidated cost of sales amounts would also be higher due to comparable increases in the purchase prices of the underlying energy commodities. The same correlation would be true in the case of lower energy commodity sales prices and purchase costs.
We attempt to mitigate commodity price exposure through our hedging activities and the use of fee-based arrangements. See Note 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.

Total consolidated revenues |  | $ | 8,543.5 |  |  | $ | 9,298.5 |

Total revenues for the first quarter of 2019 decreased $755.0 million when compared to the first quarter of 2018 primarily due to a net $870.5 million decrease in marketing revenues. Revenues from the marketing of crude oil decreased $1.01 billion quarter-to-quarter primarily due to lower sales volumes. Revenues from the marketing of petrochemicals increased a net $191.3 million quarter-to-quarter primarily due to higher sales volumes, which accounted for a $393.9 million increase, partially offset by lower sales margins, which resulted in a $202.6 million decrease.
Revenues from midstream services for the first quarter of 2019 increased $115.5 million when compared to the first quarter of 2018. Midstream service revenues from our pipeline assets increased $88.8 million quarter-to-quarter primarily due to strong demand for transportation services in Texas and on the Appalachia-to-Texas Express (“ATEX”) pipeline. NGL fractionation revenues increased $23.2 million quarter-to-quarter primarily due to higher fractionation volumes at our Mont Belvieu NGL fractionation complex.
Operating costs and expenses
Total operating costs and expenses for the first quarter of 2019 decreased $1.20 billion when compared to the first quarter of 2018 primarily due to lower cost of sales attributable to our crude oil marketing activities. The cost of sales associated with our marketing of crude oil decreased $1.34 billion quarter-to-quarter primarily due to lower sales volumes, which accounted for an $809.4 million decrease, and lower purchase prices, which accounted for an additional $534.3 million decrease.
Other operating costs and expenses for the first quarter of 2019 increased a net $41.2 million when compared to the first quarter of 2018 attributable to higher maintenance and employee compensation costs. Depreciation, amortization and accretion expense increased $56.6 million quarter-to-quarter primarily due to assets we constructed and placed into full or limited service since the first quarter of 2018 (e.g., the propane dehydrogenation (“PDH”) facility, Shin Oak NGL Pipeline and Midland-to-ECHO 2 Pipeline System). Non-cash asset impairment charges increased $3.9 million quarter-to-quarter.
General and administrative costs
General and administrative costs for the first quarter of 2019 decreased a net $0.8 million when compared to the first quarter of 2018 primarily due to higher legal and employee compensation costs.

Table of Contents
Equity in income of unconsolidated affiliates
Equity income from our unconsolidated affiliates for the first quarter of 2019 increased $38.9 million when compared to the first quarter of 2018 primarily due to an increase in earnings from our investments in crude oil pipelines.
Operating income
Operating income for the first quarter of 2019 increased $487.7 million when compared the first quarter of 2018 due to the previously described quarter-to-quarter 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 March 31, |
|  | 2019 |  |  | 2018 |
Interest charged on debt principal outstanding |  | $ | 307.5 |  |  | $ | 292.0 |
Impact of interest rate hedging program, including related amortization (1) |  |  | (1.1 | ) |  |  | 3.7 |
Interest costs capitalized in connection with construction projects (2) |  |  | (36.2 | ) |  |  | (58.2 | )
Other (3) |  |  | 7.0 |  |  |  | 14.6 |
Total |  | $ | 277.2 |  |  | $ | 252.1 |
(1) Amount presented for the three months ended March 31, 2019 and 2018 include $9.8 million and $7.2 million, respectively, of benefit from swaption premiums. (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 fluctuate period-to-period 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 the amortization of debt issuance costs. Amount presented for the first quarter of 2018 includes $7.8 million of debt issuance costs that were written off in March 2018 in connection with the redemption of junior subordinated notes. |

Interest charged on debt principal outstanding, which is the primary driver of interest expense, increased a net $15.5 million quarter-to-quarter primarily due to increased debt principal amounts outstanding during the first quarter of 2019, which accounted for a $17.8 million increase, partially offset by the effect of lower overall interest rates during the first quarter of 2019, which accounted for a $2.3 million decrease. Our weighted-average debt principal balance for the first quarter of 2019 was $26.76 billion when compared to $25.24 billion for the first quarter of 2018.
In general, our debt principal balances have increased over time due to the partial debt financing of our capital investments. For additional information regarding our debt obligations, see Note 7 of the Notes to Unaudited Condensed Consolidated Financial Statements included under Part I, Item 1 of this quarterly report. For a discussion of our capital projects, see “Capital Investments” within this Part I, Item 2.
Change in fair value of Liquidity Option Agreement
Results for the three months ended March 31, 2019 and 2018 include $57.8 million and $7.5 million, respectively, of aggregate non-cash expense attributable to accretion and changes in management estimates regarding inputs to the valuation model. Expense recognized for the first quarter of 2019 is primarily due to an approximate 1% decrease in the weighted-average cost of capital, which is used as the discount factor in determining the present value of the liability, since December 31, 2018. For additional information regarding our 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 $37.0 million gain.
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 first quarter of 2019 increased $7.2 million when compared to the first quarter of 2018 primarily due to increases in taxable margin and the Texas apportionment factor. 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.

(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. Segment gross operating margin for NGL Pipelines & Services and Crude Oil Pipelines & Services reflect adjustments for shipper make-up rights that are included in management’s evaluation of segment results. However, these adjustments are excluded from non-GAAP total gross operating margin.

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.
Estimated Impact of Temporary Closure of and Traffic Restrictions on
the Houston Ship Channel in First Quarter of 2019
On March 17, 2019, a fire occurred at a tank farm owned by a third party, Intercontinental Terminals Company (“ITC”), that is located on the Houston Ship Channel. The resulting fire lasted for several days and the channel was temporarily closed to regular ship and barge traffic for more than one week due to fire-related contamination of the waterway. Once the issues were mitigated, traffic on the Houston Ship Channel returned to normal levels in early April 2019. The Houston Ship Channel also experienced several periods of delays and restrictions due to fog in the first quarter of 2019. We estimate that gross operating margin for the first quarter of 2019 was reduced by approximately $40 million related to the impact of these events; however, we expect to recognize substantially all of this gross operating margin in the second quarter of 2019 as delayed ships and barges are rescheduled.

Natural gas processing and related NGL marketing activities
Gross operating margin from natural gas processing and related NGL marketing activities for the first quarter of 2019 increased $44.2 million when compared to the first quarter of 2018. Gross operating margin from our NGL marketing activities increased a net $24.7 million quarter-to-quarter primarily due to higher average sales margins. Results from our marketing strategies that optimize our transportation and export activities increased $30.3 million and $6.5 million, respectively, quarter-to-quarter, partially offset by a $15.9 million decrease in earnings related to the optimization of our storage assets.
Gross operating margin from our Permian Basin natural gas processing plants increased $19.2 million quarter-to-quarter primarily due to higher fee-based processing volumes, which accounted for a $16.8 million increase, and higher average sales margins, which accounted for an additional $3.9 million increase. Fee-based processing volumes at our Permian Basin natural gas processing plants increased 517 MMcf/d quarter-to-quarter primarily due to our Orla Gas Processing Plant, which commenced operations in May 2018. Gross operating margin from our South Texas natural gas processing plants increased $12.6 million quarter-to-quarter primarily due to higher average processing margins (including the impact of hedging activities), which accounted for a $7.0 million increase, and higher deficiency and processing fees, which accounted for an additional $5.0 million increase. Fee-based natural gas processing volumes and equity NGL production at our South Texas plants decreased 174 MMcf/d and 12 MBPD, respectively.
On a combined basis, gross operating margin from our natural gas processing plants in Louisiana and Mississippi increased a net $4.2 million quarter-to-quarter primarily due to higher equity NGL production volumes, which accounted for a $6.2 million increase, higher processing volumes, which accounted for an additional $5.7 million increase, partially offset by lower average processing margins, which accounted for a $4.9 million decrease. Equity NGL production volumes and natural gas fee-based processing volumes for these plants increased a combined 21 MBPD and 464 MMcf/d, respectively, quarter-to-quarter.
Gross operating margin from our Meeker, Pioneer and Chaco natural gas processing plants decreased $17.1 million quarter-to-quarter primarily due to lower equity NGL production, which accounted for a $9.0 million decrease, lower deficiency fee revenues, which accounted for a $4.6 million decrease, and lower average processing margins (including the impact of hedging activities), which accounted for an additional $3.2 million decrease. On a combined basis, fee-based natural gas processing volumes at these plants increased 140 MMcf/d and equity NGL production volumes decreased 22 MBPD quarter-to-quarter.
NGL pipelines, storage and terminals
Gross operating margin from our NGL pipelines, storage and terminal assets during the first quarter of 2019 increased $48.0 million when compared to the first quarter of 2018. Gross operating margin from our underground facilities at the Mont Belvieu hub increased $28.6 million quarter-to-quarter primarily due to higher storage fee revenues, which accounted for a $22.1 million increase, and higher product handling fee revenues, which accounted for an additional $9.4 million increase.
The Shin Oak NGL Pipeline, which was placed into limited commercial service in February 2019, contributed $8.3 million to gross operating margin for the first quarter of 2019. The Shin Oak NGL pipeline has been operating at near its current transportation capacity of 250 MBPD, which includes offloads from affiliate pipelines and 79 MBPD of direct tariff movements. Gross operating margin from our ATEX pipeline increased $4.4 million quarter-to-quarter primarily due to a 14 MBPD increase in transportation volumes. Gross operating margin from terminals connected to our Mid-America Pipeline System increased $4.4 million quarter-to-quarter due to increased demand for terminal services. Gross operating margin from our Morgan’s Point Ethane Export Terminal increased $3.9 million primarily due to higher loading volumes of 18 MBPD. Gross operating margin from our South Louisiana NGL Pipeline System increased $3.2 million quarter-to-quarter primarily due to a 68 MBPD increase in transportation volumes.
Gross operating margin from EHT decreased $5.4 million quarter-to-quarter primarily due to lower LPG exports, which decreased 49 MBPD. Ship and barge traffic scheduled at EHT was adversely impacted by temporary closures and restrictions impacting the Houston Ship Channel during the first quarter of 2019.

NGL fractionation
Gross operating margin from NGL fractionation for the first quarter of 2019 decreased $17.9 million when compared to the first quarter of 2018. Gross operating margin at our Hobbs NGL fractionator decreased $21.0 million quarter-to-quarter primarily due to major maintenance activities completed in February 2019. NGL fractionation volumes at Hobbs decreased 20 MBPD.
Gross operating margin from our Mont Belvieu NGL fractionation complex increased a net $4.1 million quarter-to-quarter primarily due to higher fractionation volumes, which accounted for a $16.7 million increase, partially offset by higher operating costs, which accounted for a $12.3 million decrease. NGL fractionation volumes at our Mont Belvieu NGL fractionation complex increased 120 MBPD (net to our interest), primarily due to the start-up of our ninth NGL fractionator in May 2018. Gross operating margin from our equity investment in Promix increased $1.7 million quarter-to-quarter primarily due to higher fractionation volumes of 15 MBPD. Our Tebone NGL fractionator, which was restarted in February 2019 in light of regional demand for fractionation services, contributed 18 MBPD of fractionation volumes to the first quarter of 2019 results. Gross operating margin from Tebone for the first quarter of 2019 was a loss of $2.7 million due to start-up expenses.
Crude Oil Pipelines & Services
The following table presents segment gross operating margin and selected volumetric data for the Crude Oil Pipelines & Services segment for the periods indicated (dollars in millions, volumes as noted):

|  | For the Three Months Ended March 31, |
|  | 2019 |  |  | 2018 |
Segment gross operating margin |  | $ | 662.3 |  |  | $ | 220.0 |
Selected volumetric data: |  |  |  |  |  |  |  |
Crude oil pipeline transportation volumes (MBPD) |  |  | 2,227 |  |  |  | 1,997 |
Crude oil marine terminal volumes (MBPD) |  |  | 886 |  |  |  | 634 |

Gross operating margin from our Crude Oil Pipelines & Services segment for the first quarter of 2019 increased $442.3 million when compared to the first quarter of 2018.
Gross operating margin from our Midland-to-ECHO 1 Pipeline System and related business activities increased $221.0 million quarter-to-quarter primarily due to changes in non-cash mark-to-market earnings, which were a $67.2 million benefit in the first quarter of 2019 compared to a $114.0 million loss in the first quarter of 2018, and lower expenses, which accounted for a $28.9 million increase. Gross operating margin for the first quarter of 2018 was reduced by $24.2 million in connection with the expected allocation of pipeline earnings to Western Gas Partners, LP (“Western”) upon closing of their acquisition of a 20% ownership interest in Whitethorn Pipeline Company LLC (“Whitethorn”), which owns the majority of the Midland-to-ECHO 1 Pipeline System. Western acquired its interest in Whitethorn in June 2018. Transportation volumes for the Midland-to-ECHO 1 Pipeline System increased 58 MBPD quarter-to-quarter.
The mark-to-market earnings attributable to the Midland-to-ECHO 1 Pipeline System are associated with the hedging of crude oil market price differentials (basis spreads) between the Midland and Houston area markets. At March 31, 2019, these hedges, which were primarily entered into during 2017, serve to lock in a $2.75 per barrel positive margin on our anticipated purchases of crude oil at Midland and subsequent anticipated sales to customers in the Houston area for periods extending predominantly into 2019 and minimally through 2020. The volume hedged through 2020 varies from quarter-to-quarter and year-to-year; however, the hedge levels generally correspond to pipeline capacity currently expected to be available to us on the Midland-to-ECHO 1 Pipeline System as customer commitment volumes ramp up to peak levels. The mark-to-market gain for the first quarter of 2019 reflects a decrease in the basis spread between the Midland and Houston markets since December 31, 2018 to an average of $4.51 per barrel through 2020 relative to our average hedged amount of $2.75 per barrel across these same periods (as of March 31, 2019). When the forecasted physical receipts and deliveries of crude oil ultimately occur in the future, we will realize a physical gross margin at then-prevailing commodity price spreads; however the realized settlement of the associated financial hedges would convert that physical margin to the average $2.75 per barrel spread of the financial hedges. The basis spread between the Midland and Houston markets continues to fluctuate.

Gross operating margin from other crude oil marketing activities increased $132.5 million primarily due to higher average sales margins, which accounted for an $83.6 million increase, and higher non-cash mark-to-market earnings, which accounted for an additional $48.1 million increase. Non-cash mark-to-market earnings for this business was a gain of $32.6 million during the first quarter of 2019 compared to a loss of $15.5 million during the first quarter of 2018. The higher crude oil marketing earnings relate to higher market price differentials for crude oil between the Permian Basin region, Cushing hub and Gulf Coast markets.
Gross operating margin from our West Texas System and equity investment in the Eagle Ford Crude Oil Pipeline System increased a combined $27.4 million quarter-to-quarter primarily due to higher transportation volumes of 52 MBPD (net to our interest). Gross operating margin from our Midland-to-ECHO 2 Pipeline System, which was in limited commercial service during the first quarter of 2019, was $17.4 million on transportation volumes of 147 MBPD.

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 Three Months Ended March 31, |
|  | 2019 |  |  | 2018 |
Net cash flows provided by operating activities |  | $ | 1,160.4 |  |  | $ | 1,233.6 |
Cash used in investing activities |  |  | 1,174.5 |  |  |  | 1,119.1 |
Cash provided by (used in) financing activities |  |  | (288.5 | ) |  |  | 30.8 |

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 quarter-to-quarter fluctuations in our consolidated cash flow amounts:
Operating activities
Net cash flows provided by operating activities for the first quarter of 2019 decreased a net $73.2 million when compared to the first quarter of 2018 primarily due to:

§ | a $356.7 million decrease quarter-to-quarter primarily due to the timing of cash receipts and payments related to operations; partially offset by

§ | a $252.0 million increase quarter-to-quarter resulting from higher partnership earnings in the first quarter of 2019 when compared to the first quarter of 2018 (after adjusting our $368.9 million increase in net income quarter-to-quarter for changes in the non-cash items identified on our Unaudited Condensed Statements of Consolidated Cash Flows); and

§ | a $31.5 million increase quarter-to-quarter in cash distributions received on earnings from unconsolidated affiliates attributable to our investments in NGL and crude oil pipeline joint ventures.

§ | a $149.8 million decrease quarter-to-quarter in net cash used for business combinations. We used $149.8 million in the first quarter of 2018 to acquire the remaining 50% equity interest in Delaware Processing.

Financing activities
Cash used in financing activities for the first quarter of 2019 increased a net $319.3 million when compared to the first quarter of 2018 primarily due to:

§ | a net $145.9 million decrease quarter-to-quarter in net cash inflows from debt. In the first quarter of 2019, we issued $1.4 billion principal amount of short-term notes under EPO’s commercial paper program, partially offset by the repayment of $700 million principal amount of Senior Notes N. In the first quarter of 2018, we issued $2.7 billion aggregate principal amount of senior notes and junior subordinated notes, partially offset by the repayment of $1.18 billion principal amount of short-term notes under EPO’s commercial paper program and the redemption of all $682.7 million outstanding aggregate principal amount of its Junior Subordinated Notes B;

§ | a $134.3 million decrease quarter-to-quarter in net cash proceeds from the issuance of common units in connection with our DRIP and EUPP;

§ | the use of $51.6 million in the first quarter of 2019 to acquire 1,852,392 common units under the 2019 Buyback Program; and

§ | a $31.9 million increase quarter-to-quarter in cash distributions paid to limited partners primarily due to an increase in the quarterly cash distribution rate per unit; partially offset by,

§ | a $34.7 million increase quarter-to-quarter in cash contributions from noncontrolling interests.

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 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.

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 we receive from noncontrolling interests, net of any distributions paid to such 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 March 31, 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):

|  | For the Three Months Ended March 31, |  |  | For the Twelve Months Ended March 31, |
|  | 2019 |  |  | 2018 |  |  | 2019 |

Capital Investments
We currently have $5.0 billion of growth capital projects scheduled to be completed by mid-2020 including:

§ | the completion of joint venture-owned dock infrastructure in Corpus Christi designed to accommodate crude oil volumes (second quarter of 2019),

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

§ | expansion of our Front Range and Texas Express NGL pipelines (third quarter of 2019),

§ | increase in LPG loading capacity at EHT (third quarter of 2019),

§ | our isobutane dehydrogenation (“ iBDH”) facility (fourth quarter of 2019),

§ | the Shin Oak NGL pipeline (full service expected in fourth quarter of 2019),

§ | our ethylene export terminal (fourth quarter of 2019 through the fourth quarter of 2020),

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

60

Table of Contents

§ | 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).

Based on information currently available, we expect our total capital investments for 2019 to approximate $3.8 billion to $4.2 billion, which reflects growth capital expenditures of $3.4 billion to $3.8 billion and $350 million for sustaining capital expenditures.
Our forecast of capital investments for 2019 is based on our announced strategic operating and growth plans (through the filing date of this quarterly report), which are dependent upon our ability to generate the required funds from either operating cash flows or other means, including borrowings under debt agreements, the issuance of additional equity and debt securities, and potential divestitures. We may revise our forecast of capital 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 as a result of 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 costs and risks, continues to be a significant factor in determining how much capital we can invest. We believe our access to capital resources is sufficient to meet the demands of our current and future growth needs and, although we expect to make the forecast capital expenditures noted above, we may adjust the timing and amounts of projected expenditures in response to changes in capital market conditions.
The following table summarizes the primary elements of our capital investments for the periods indicated (dollars in millions):

|  | For the Three Months Ended March 31, |
|  | 2019 |  |  | 2018 |
Capital investments for property, plant and equipment: (1) |  |  |  |  |  |
Growth capital projects (2) |  | $ | 1,077.4 |  |  | $ | 873.3 |
Sustaining capital projects (3) |  |  | 71.5 |  |  |  | 73.2 |
Total |  | $ | 1,148.9 |  |  | $ | 946.5 |
Cash used for business combinations, net |  | $ | -- |  |  | $ | 149.8 |
Investments in unconsolidated affiliates |  | $ | 29.1 |  |  | $ | 37.9 |
(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 spending for growth capital projects and investments in unconsolidated affiliates are explained in large part by increases or decreases in spending on major expansion projects. Our most significant growth capital expenditures for the three months ended March 31, 2019 involved projects to support crude oil, natural gas and NGL production from the Permian Basin, export activities at our Gulf Coast terminals and spending on our iBDH unit. Fluctuations in spending for sustaining capital projects are explained in large part by the timing and cost of pipeline integrity and similar projects.
Comparison of Three Months Ended March 31, 2019 with Three Months Ended March 31, 2018
Investments in growth capital projects at our Mont Belvieu complex increased $149.7 million quarter-to-quarter primarily due to increased expenditures at our iBDH unit, which accounted for a $126.4 million increase, and Frac X and Frac XI, which accounted for an additional $118.0 million increase, partially offset by lower expenditures at our PDH facility and ninth Mont Belvieu area NGL fractionator (“Frac IX”), which accounted for a combined $115.8 million decrease. Our PDH facility and Frac IX were placed into service during the second quarter of 2018.
61

Table of Contents
Our growth capital investments in support of Permian Basin production increased $70.4 million quarter-to-quarter primarily due to increased expenditures for our Shin Oak NGL Pipeline, which accounted for a $109.5 million increase, and the conversion of a portion of our Seminole NGL Pipeline system to crude oil service (the Midland-to-ECHO 2 Pipeline System), which accounted for an additional $62.1 million increase, partially offset by lower expenditures at our Orla natural gas processing facility, which accounted for a $100.8 million decrease.
Investments in our ethylene export terminal and related assets increased $63.1 million quarter-to-quarter.
Net cash used for business combinations in the first quarter of 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 $27.12 billion at March 31, 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.
During the first quarter of 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 $3.2 billion, with $1.1 billion committed over the next five years and $2.1 billion thereafter. At March 31, 2019, our estimated long-term purchase obligations totaled $13.5 billion after reflecting the agreements added in the first quarter of 2019 and those commitments that expired during the quarter. 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 March 31, 2019 (volume measures as noted):

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

(1) Volume for derivatives designated as hedging instruments reflects the total amount of volumes hedged whereas volume for derivatives not designated as hedging instruments reflects the absolute value of derivative notional volumes. (2) The maximum term for derivatives designated as cash flow hedges, derivatives designated as fair value hedges and derivatives not designated as hedging instruments is December 2020, December 2019 and December 2020, respectively. (3) Current volumes include 14.0 Bcf of physical derivative instruments that are predominantly priced at a market-based index plus a premium or minus a discount related to location differences. (4) Reflects the use of derivative instruments to manage risks associated with transportation, processing and storage assets.

At March 31, 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.

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.

The fair value of our crude oil marketing portfolio decreased since March 31, 2019 primarily due to higher crude oil prices.
Interest Rate Hedging Activities
We may utilize interest rate swaps, forward starting swaps and similar derivative instruments to manage our exposure to changes in interest rates charged on borrowings under certain consolidated debt agreements. This strategy may be used in controlling our overall cost of capital associated with such borrowings. The composition of our derivative instrument portfolios may change depending on our hedging requirements. We have no interest rate hedging instruments outstanding as of the filing date of this quarterly report.

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 first 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.
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.
ITEM 1A. RISK FACTORS.
An investment in our securities involves certain risks. Security holders and potential investors in our securities should carefully consider the risks described under “Risk Factors” set forth in Part I, Item 1A of our 2018 Form 10-K, in addition to other information in such annual report. The risk factors set forth in our 2018 Form 10-K are important factors that could cause our actual results to differ materially from those contained in any written or oral forward-looking statements made by us or on our behalf.
