Note 1.  Partnership Organization and Basis of Presentation

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

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

Our results of operations for the three months ended March 31, 2018 are not necessarily indicative of results expected for the full year of 2018.  In our opinion, the accompanying Unaudited Condensed Consolidated Financial Statements include all adjustments consisting of normal recurring accruals necessary for fair presentation.  Although we believe the disclosures in these financial statements are adequate and make the information presented not misleading, certain information and footnote disclosures normally included in annual financial statements prepared in accordance with United States (“U.S.”) generally accepted accounting principles (“GAAP”) have been condensed or omitted pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”).

ENTERPRISE PRODUCTS PARTNERS L.P.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

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, 2017  (the “2017 Form 10-K”) filed with the SEC on February 28, 2018.

Note 2.  Summary of Significant Accounting Policies

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

Adoption of New Revenue Recognition Policies on January 1, 2018

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

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

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

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

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

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

ENTERPRISE PRODUCTS PARTNERS L.P.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

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

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

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

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

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

See Note 9 regarding our new revenue disclosures.

Impact of ASU 2016-18 on Restricted Cash Disclosures

We adopted Accounting Standard Update (“ASU”) No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash, in the fourth quarter of 2017 and applied this ASU retrospectively to the periods presented in our Unaudited Condensed Statements of Consolidated Cash Flows.  As a result, the decrease in restricted cash of $309.8 million was excluded from net cash used in investing activities for the three months ended March 31, 2017.

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

	March 31, 2018		December 31, 2017
Cash and cash equivalents	$	102.1	$	5.1
Restricted cash		113.5		65.2
Total cash, cash equivalents and restricted cash shown in the   Unaudited Condensed Statements of Consolidated Cash Flows	$	215.6	$	70.3

ENTERPRISE PRODUCTS PARTNERS L.P.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

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, 2018 consisted of initial margin requirements of $28.2 million and variation margin requirements of $85.3 million.

In February 2016, the FASB issued ASC 842, Leases (“ASC 842”), which requires substantially all leases (with the exception of leases with a term of one year or less) to be recorded on the balance sheet using a method referred to as the right-of-use (“ROU”) asset approach. We will adopt the new standard on January 1, 2019 and apply it to (i) all new leases entered into after January 1, 2019 and (ii) all existing lease contracts as of January 1, 2019 through a cumulative adjustment to equity.  In accordance with this approach, our consolidated operating expenses for periods prior to January 1, 2019 will not be revised.

The new standard introduces two lease accounting models, which result in a lease being classified as either a “finance” or “operating” lease on the basis of whether the lessee effectively obtains control of the underlying asset during the lease term.  A lease would be classified as a finance lease if it meets one of five classification criteria, four of which are generally consistent with current lease accounting guidance.  By default, a lease that does not meet the criteria to be classified as a finance lease will be deemed an operating lease.  Regardless of classification, the initial measurement of both lease types will result in the balance sheet recognition of a 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.  Leases classified as a finance lease will be accounted for using the effective interest method.  Under this approach, a lessee will amortize the ROU asset (generally on a straight-line basis in a manner similar to depreciation) and the discount on the lease liability (as a component of interest expense).  Leases classified as an operating lease will result in the recognition of a single lease expense amount that is recorded on a straight-line basis (or another systematic basis, if more appropriate).

We are in the process of reviewing our lease agreements in light of the new guidance.  We anticipate that ASC 842 will result in changes to the way our operating leases are recorded, presented and disclosed in our consolidated financial statements.

Our minimum payment obligations under operating leases with terms in excess of one year totaled $431.9 million at March 31, 2018 (undiscounted). Upon adoption, we expect to recognize a ROU asset and a corresponding lease liability based on the present value of such obligations.  We currently do not have any capital lease obligations.

Parent-Subsidiary Guarantor Relationships

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

Issuance of $2.0 Billion of Senior Notes and $700 Million of Junior Subordinated Notes in February 2018

In February 2018, EPO issued $2.7 billion aggregate principal amount of notes comprised of (i) $750 million principal amount of senior notes due February 15, 2021 (“Senior Notes TT”), (ii) $1.25 billion principal amount of senior notes due February 15, 2048 (“Senior Notes UU”) and (iii) $700 million principal amount of junior subordinated notes due February 15, 2078 (“Junior Subordinated Notes F”).

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

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

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

Redemption of Junior Subordinated Notes B

On February 1, 2018, EPO notified its trustee and paying agent to redeem all of the $682.7 million outstanding aggregate principal amount of its Junior Subordinated Notes B.  The Junior Subordinated Notes B were redeemed on March 5, 2018 at a price equal to 100% of the principal amount of the notes being redeemed, plus all accrued and unpaid interest thereon to, but not including, the redemption date.

Note 8.  Equity and Distributions

Partners’ Equity

The following table summarizes changes in the number of our limited partner common units outstanding from January 1, 2018 to March 31, 2018:

Number of common units outstanding at January 1, 2018	2,161,089,479
Common units issued in connection with DRIP and EUPP	6,642,286
Common units issued in connection with the vesting of phantom unit awards	3,170,861
Cancellation of treasury units acquired in connection with the vesting of equity-based awards	(949,778	)
Common units issued in connection with employee compensation	1,443,586
Other	16,360
Number of common units outstanding at March 31, 2018	2,171,412,794

The net cash proceeds we received from the issuance of common units during the three months ended March 31, 2018 were used to temporarily reduce amounts outstanding under EPO’s commercial paper program and revolving credit facilities and for general company purposes.

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

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

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

During the three months ended March 31, 2018, we did not issue any common units under the ATM program.  During the three months ended March 31, 2017, we issued 12,865,371 common units under this program for aggregate gross cash proceeds of $359.7 million, resulting in total net cash proceeds of $356.0 million.

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

Distribution reinvestment plan.  We have a registration statement on file with the SEC in connection with our distribution reinvestment plan (“DRIP”).  The DRIP provides unitholders of record and beneficial owners of our common units a voluntary means by which they can increase the number of our common units they own by reinvesting the quarterly cash distributions they receive from us into the purchase of additional new common units.

Note 9.  Revenues

We classify our revenues into sales of products and midstream services.  Product sales relate primarily to our various marketing activities whereas midstream services represent our other integrated businesses (i.e., gathering, processing, transportation, fractionation, storage and terminaling).  The following table presents our revenues by business segment, and further by revenue type, for the periods indicated:

	For the Three Months Ended March 31,
	2018 (1)		2017 (2)
NGL Pipelines & Services:
Sales of NGLs and related products	$	2,815.4	$	2,887.2
Midstream services		597.9		458.6
Total		3,413.3		3,345.8

Sales of crude oil		3,341.7		1,618.6
Midstream services		229.2		188.6
Total		3,570.9		1,807.2
Natural Gas Pipelines & Services:
Sales of natural gas		560.0		544.0
Midstream services		244.8		217.2
Total		804.8		761.2
Petrochemical & Refined Products Services:
Sales of petrochemicals and refined products		1,289.3		1,211.1
Midstream services		220.2		195.1
Total		1,509.5		1,406.2
Total consolidated revenues	$	9,298.5	$	7,320.4
(1)   Revenues are accounted for under ASC 606 upon implementation at January 1, 2018. (2)   Revenues are accounted for under ASC 605 for historical periods prior to January 1, 2018.

Substantially all of our revenues are derived from contracts with customers as defined within ASC 606.  In total, product sales and midstream services accounted for 86% and 14%, respectively, of our consolidated revenues for the three months ended March 31, 2018 and 2017.

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

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

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

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

20

ENTERPRISE PRODUCTS PARTNERS L.P.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

The additional service revenue recognized for the non-cash consideration increased our total revenues by approximately 1% for the three months ended March 31, 2018 when compared to the amount of revenues we would have recognized under ASC 605 for the quarter.  Given the rapid turnover of our inventories of NGL products each month, we do not expect a significant change in our gross operating margin from natural gas processing and related NGL marketing activities as a result of the changes required by ASC 606.

Unbilled Revenue and Deferred Revenue

The following table provides information regarding our contract assets and contract liabilities as of March 31, 2018:

Contract Asset	Location	Balance
Unbilled revenue (current amount)	Prepaid and other current assets	$	64.4
Unbilled revenue (noncurrent)	Other assets		0.2
Total		$	64.6

Contract Liability	Location	Balance
Deferred revenue (current amount)	Other current liabilities	$	78.5
Deferred revenue (noncurrent)	Other long-term liabilities		140.6
Total		$	219.1

The following table presents significant changes in our unbilled revenue and deferred revenue balances during the three months ended March 31, 2018:

	Unbilled Revenue		Deferred Revenue
Balance at January 1, 2018 (upon adoption of ASC 606)	$	--	$	224.7
Amount included in opening balance transferred to other accounts during period (1)		--		(54.0	)
Amount recorded during period		62.4		86.0
Amounts recorded during period transferred to other accounts (1)		--		(37.6	)
Amount recorded in connection with business combination		2.2		--
Balance at March 31, 2018	$	64.6	$	219.1
(1)   Unbilled revenues are transferred to accounts receivable once we have an unconditional right to consideration from the customer. Deferred revenues are recognized as revenue upon satisfaction of our performance obligation to the customer.

Remaining Performance Obligations

The following table presents estimated fixed consideration from contracts with customers that contain minimum volume commitments, deficiency and similar fees and the term of the contracts exceeds one year. These amounts represent the revenues we expect to recognize in future periods from these contracts as of March 31, 2018.  For a significant portion of our revenue, we bill customers a contractual rate for the services provided multiplied by the amount of volume handled in a given period.  We have the right to invoice the customer in the amount that corresponds directly with the value of our performance completed to date.  Therefore, we are not required to disclose information about the variable consideration of remaining performance obligations as we recognize revenue equal to the amount that we have the right to invoice.

Impact of Change in Accounting Policy – ASC 606 Transition Disclosures

The following information and tables are provided to summarize the material impacts of adopting ASC 606 on our consolidated financial statements for the three months ended March 31, 2018.

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

Unbilled revenues have historically been presented as a component of accounts receivable on our consolidated balance sheets.  Upon implementation of ASC 606, we reclassified these amounts to “Prepaid and other current assets” since these amounts represent conditional rights to consideration.  Once we have an unconditional right to consideration, the amount is transferred to accounts receivable.

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

Note 10.  Business Segments

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

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

Segment Gross Operating Margin

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

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

	For the Three Months Ended March 31,
	2018			2017
Operating income	$	1,138.5		$	1,031.6
Adjustments to reconcile operating income to total gross operating margin:
Add depreciation, amortization and accretion expense in operating costs and expenses		394.3			376.2
Add asset impairment and related charges in operating costs and expenses		0.9			11.2
Subtract net gains attributable to asset sales in operating costs and expenses		(0.5	)		(0.3	)
Add general and administrative costs		53.0			50.4
Adjustments for make-up rights on certain new pipeline projects:
Add non-refundable payments received from shippers attributable to make-up rights (1)		2.7			13.3
Subtract the subsequent recognition of revenues attributable to make-up rights (2)		(14.2	)		(9.1	)
Total segment gross operating margin	$	1,574.7		$	1,473.3
(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.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

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

Note 11.   Business Combinations

On March 29, 2018, we acquired the remaining 50% member interest in our Delaware Processing joint venture for $153.6 million in cash.  As a result, Delaware Processing is now our wholly-owned consolidated subsidiary.  Delaware Processing owns a cryogenic natural gas processing facility having a capacity of 150 million cubic feet per day.  The facility is located in Reeves County, Texas and entered service in August 2016.  The acquired business serves growing production of NGL-rich natural gas from the Delaware Basin in West Texas and southern New Mexico.

The following table presents the preliminary fair value allocation of assets acquired and liabilities assumed in the acquisition at March 29, 2018. Due to the recent nature of this transaction, the allocation is provisional and subject to ongoing efforts to clarify the values assigned to tangible and identifiable intangible assets. We expect these open matters to be resolved by the end of the second quarter of 2018.

Cash paid for remaining 50% equity interest in Delaware Processing	$	153.6
Fair value of our 50% equity interest in Delaware Processing held before the acquisition		146.4
Total		300.0
Recognized amounts of identifiable assets acquired and liabilities assumed:
Assets acquired in business combination:
Current assets, including cash of $3.8 million	$	12.7
Property, plant and equipment		200.0
Contract-based intangible assets		78.8

Current liabilities	$	(1.3	)
Long-term liabilities		(0.6	)
Total liabilities assumed	$	(1.9	)
Total identifiable net assets	$	300.0
Goodwill	$	--

Prior to this acquisition, we accounted for our investment using the equity method.  On a historical pro forma basis, our revenues, costs and expenses, operating income, net income attributable to Enterprise Products Partners L.P. and earnings per unit amounts for the three months ended March 31, 2018 and 2017 would not have differed materially from those we actually reported had the acquisition been completed on January 1, 2017 rather than March 29, 2018.

At March 29, 2018, our 50% equity investment in Delaware Processing was $109.4 million.  Upon acquisition of the remaining 50% member interest, our existing equity investment was remeasured to fair value resulting in the recognition of a non-cash $37.0 million gain, which is presented within Other Income on our Unaudited Condensed Consolidated Statement of Operations for the three months ended March 31, 2018.

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

The following table presents our calculation of basic and diluted earnings per unit for the periods indicated:

	For the Three Months Ended March 31,
	2018			2017
BASIC EARNINGS PER UNIT
Net income attributable to limited partners	$	900.7		$	760.7
Undistributed earnings allocated and cash payments on phantom unit awards (1)		(4.7	)		(4.0	)
Net income available to common unitholders	$	896.0		$	756.7
Basic weighted-average number of common units outstanding		2,166.9			2,126.2
Basic earnings per unit	$	0.41		$	0.36
DILUTED EARNINGS PER UNIT
Net income attributable to limited partners	$	900.7		$	760.7
Diluted weighted-average number of units outstanding:
Distribution-bearing common units		2,166.9			2,126.2
Phantom units (1)		10.3			8.7
Total		2,177.2			2,134.9
Diluted earnings per unit	$	0.41		$	0.36
(1)   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. As a result, the phantom units are considered participating securities for purposes of computing basic earnings per unit.

Note 13.  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,
	2018		2017
Equity-classified awards:
Phantom unit awards	$	24.6	$	22.8
Restricted common unit awards		--		0.5
Profits interest awards		1.6		1.5
Liability-classified awards		0.1		0.2
Total	$	26.3	$	25.0

The fair value of equity-classified awards is amortized into 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.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

At March 31, 2018, all of the outstanding phantom unit awards were granted under the 2008 Plan.  The maximum number of common units authorized for issuance under the 2008 Plan was 45,000,000 at March 31, 2018.  This amount will automatically increase under the terms of the 2008 Plan by 5,000,000 common units on January 1, 2019 and will continue to automatically increase annually on each January 1 thereafter during the term of the 2008 Plan; provided, however, that in no event shall the maximum aggregate number exceed 70,000,000 common units.  After giving effect to awards granted under the 2008 Plan through March 31, 2018, a total of 18,717,222  additional common units were available for issuance under this plan.

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

Phantom Unit Awards

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

At March 31, 2018, substantially all of our phantom unit awards are expected to result in the issuance of common units upon vesting; therefore, the applicable awards are accounted for as equity-classified awards.  The grant date fair value of a phantom unit award is based on the market price per unit of our common units on the date of grant.  Compensation expense is recognized based on the grant date fair value, net of an allowance for estimated forfeitures, over the requisite service or vesting period.

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

	Number of Units			Weighted- Average Grant Date Fair Value per Unit (1)
Phantom unit awards at January 1, 2018		9,289,501		$	27.65
Granted (2)		4,940,081		$	26.81
Vested		(3,170,861	)	$	28.64
Forfeited		(74,656	)	$	26.98
Phantom unit awards at March 31, 2018		10,984,065		$	26.99
(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 2018 was $132.4 million based on a grant date market price of our common units ranging from $25.40 to $26.81 per unit. An estimated annual forfeiture rate of 3.2% was applied to these awards.

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

The following table presents supplemental information regarding phantom unit awards for the periods indicated:

	For the Three Months Ended March 31,
	2018		2017
Cash payments made in connection with DERs	$	3.9	$	3.2
Total intrinsic value of phantom unit awards that vested during period		82.0		63.2

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

For the EPCO group of companies, the unrecognized compensation cost associated with phantom unit awards was $187.5 million at March 31, 2018, of which our share of the cost is currently estimated to be $160.7 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

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

The following table summarizes key elements of each Employee Partnership as of March 31, 2018:

Employee Partnership	Enterprise Common Units contributed to Employee Partnership by EPCO Holdings	Class A Capital      Base (1)	Class A Preference Return (2)		Expected Vesting/ Liquidation Date	Estimated Grant Date Fair Value of Profits Interest   Awards (3)	Unrecognized Compensation   Cost (4)
PubCo I	2,723,052	$63.7 million	$	0.39	Feb. 2020	$13.2 million	$6.6 million
PubCo II	2,834,198	$66.3 million	$	0.39	Feb. 2021	$14.7 million	$8.6 million
PubCo III	105,000	$2.5 million	$	0.39	Apr. 2020	$0.5 million	$0.3 million
PrivCo I	1,111,438	$26.0 million	$	0.39	Feb. 2021	$5.8 million	$0.7 million
(1)   Represents fair market value of the Enterprise common units contributed to each Employee Partnership at the applicable contribution date. (2)   Each quarter, the Class A limited partner in each Employee Partnership is paid a cash distribution equal to the product of (i) the number of common units owned by the Employee Partnership and (ii) the Class A Preference Return of $0.39 per unit (subject to equitable adjustment in order to reflect any equity split, equity distribution or dividend, reverse split, combination, reclassification, recapitalization or other similar event affecting such common units). To the extent that the Employee Partnership has cash remaining after making this quarterly payment to the Class A limited partner, the residual cash is distributed to the Class B limited partners on a quarterly basis. (3)   Represents the total grant date fair value of the profits interest awards irrespective of how such costs will be allocated between us and EPCO and its privately held affiliates. (4)   Represents our expected share of the unrecognized compensation cost at March 31, 2018. We expect to recognize our share of the unrecognized compensation cost for PubCo I, PubCo II, PubCo III and PrivCo I over a weighted-average period of 1.9 years, 2.9 years, 2.0 years and 2.9 years, respectively.

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

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

	Expected	Risk-Free	Expected	Expected Unit
Employee	Life	Interest	Distribution	Price
Partnership	of Award	Rate	Yield	Volatility
PubCo I	4.0 years	0.9% to 2.2%	6.2% to 7.0%	24% to 40%
PubCo II	5.0 years	1.1% to 2.3%	6.1% to 7.0%	27% to 40%
PubCo III	4.0 years	1.0% to 2.2%	6.1% to 6.8%	27% to 40%
PrivCo I	5.0 years	1.2% to 1.6%	6.1% to 6.7%	28% to 40%

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

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

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

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

Interest Rate Hedging Activities

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

The following table summarizes our portfolio of interest rate swaps at March 31, 2018:

Hedged Transaction	Number and Type of Derivatives Outstanding	Notional Amount		Period of Hedge	Rate Swap	Accounting Treatment
Senior Notes OO	10 fixed-to-floating swaps	$	750.0	5/2015 to 5/2018	1.65% to 2.27%	Fair value hedge

The carrying amount of the Senior Notes OO was $749.4 million and $748.6 million at March 31, 2018 and December 31, 2017, respectively.  These carrying amounts, which are presented in “Current maturities of debt” on our Unaudited Condensed Consolidated Balance Sheets, are inclusive of cumulative fair value hedging adjustments of $0.6 million and $1.4 million at March 31, 2018 and December 31, 2017, respectively.

The following table summarizes our portfolio of forward starting swaps at March 31, 2018:

Hedged Transaction	Number and Type of Derivatives Outstanding	Notional Amount		Expected Settlement Date	Average Rate Locked	Accounting Treatment
Future long-term debt offering	2 forward starting swaps	$	175.0	2/2019	2.56%	Cash flow hedge

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

We sold swaptions related to our interest rate hedging activities during the first quarter of 2018, which resulted in the recognition of $7.2 million of cash gains that are reflected as a reduction in interest expense for the quarter. The swaptions expired in March 2018.

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

ENTERPRISE PRODUCTS PARTNERS L.P.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

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

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

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

The following table summarizes our portfolio of commodity derivative instruments outstanding at March 31, 2018 (volume measures as noted):

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

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

Our Level 3 financial liabilities at March 31, 2018 and December 31, 2017 primarily reflect the fair value assigned to the Liquidity Option Agreement (see Note 16) at each measurement date.  The carrying value of the Liquidity Option Agreement (a long-term liability) was $341.4 million and $333.9 million at March 31, 2018 and December 31, 2017, respectively.

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	2018			2017
Financial liability balance, net, January 1		$	(332.7	)	$	(268.2	)
Total gains (losses) included in:
Net income (1)	Revenue		(0.5	)		0.7
Net income	Other expense, net		(7.5	)		(5.5	)
Other comprehensive income (loss)	Commodity derivative instruments – changes in fair value of cash flow hedges		--			--
Settlements (1)	Revenue		(1.2	)		(1.4	)
Transfers out of Level 3			--			--
Financial liability balance, net, March 31		$	(341.9	)	$	(274.4	)
(1)   There were unrealized losses of $1.7 million and unrealized losses of $0.7 million included in these amounts for the three months ended March 31, 2018 and 2017, respectively.

The followingtable provides quantitative information regarding our recurring Level 3 fair value measurements for commodity derivatives at March 31, 2018:

	Fair Value
	Financial Assets		Financial Liabilities		Valuation Techniques	Unobservable Input	Range
Commodity derivatives – Crude oil	$	0.4	$	0.9	Discounted cash flow	Forward commodity prices	$63.78-$65.07/barrel
Total	$	0.4	$	0.9

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, 2018.  In general, changes in the price of the underlying commodity increases or decreases the fair value of a commodity derivative depending on whether the derivative was purchased or sold.  We generally expect changes in the fair value of our derivative instruments to be offset by corresponding changes in the fair value of our hedged exposures.

Nonrecurring Fair Value Measurements

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 $24.73  billion and $23.47 billion at March 31, 2018 and December 31, 2017, respectively.  The aggregate carrying value of these debt obligations was $23.50 billion and $21.48 billion at March 31, 2018 and December 31, 2017, respectively.  These values are based on quoted market prices for such debt or debt of similar terms and maturities (Level 2), our credit standing and the credit standing of our counterparties.  Changes in market rates of interest affect the fair value of our fixed-rate debt.  The amounts reported for fixed-rate debt obligations exclude those amounts hedged using fixed-to-floating interest rate swaps. See “Interest Rate Hedging Activities” within this Note 14 for additional information.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.

Total	$	83.0	$	127.3

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

Total Number  of Units	Percentage of Total Units Outstanding
693,530,754	32%

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, 81,346,154 have been pledged as security under the credit facilities of EPCO and its privately held affiliates at March 31, 2018.  These credit facilities contain customary and other events of default, including defaults by us and other affiliates of EPCO.  An event of default, followed by a foreclosure on the pledged collateral, could ultimately result in a change in ownership of these units and affect the market price of our common units.

We and Enterprise GP are both separate legal entities apart from each other and apart from EPCO and its other affiliates, with assets and liabilities that are also separate from those of EPCO and its other affiliates.  EPCO and its privately held affiliates depend on the cash distributions they receive from us and other investments to fund their other activities and to meet their debt obligations.  During the three months ended March 31, 2018 and 2017, we paid EPCO and its privately held affiliates cash distributions totaling $286.9  million and $275.2 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, 2018, privately held affiliates of EPCO reinvested $100 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,
	2018		2017
Operating costs and expenses	$	223.0	$	211.6
General and administrative expenses		29.2		26.8
Total costs and expenses	$	252.2	$	238.4

Note 16.  Commitments and Contingencies

Litigation

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

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

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

ENTERPRISE PRODUCTS PARTNERS L.P.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

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

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

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

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

On 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.  As of March 31, 2018, we have not recorded a provision for this matter as management continues to believe that payment of damages by us in this case is not probable. We continue to monitor developments involving this matter.

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

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

Contractual Obligations

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

Operating Lease Obligations.  Consolidated lease and rental expense was $25.6 million and $26.2 million during the three months ended March 31, 2018 and 2017, respectively.  Our operating lease commitments at March 31, 2018 did not differ materially from those reported in our 2017 Form 10-K.

Purchase Obligations.  Our consolidated purchase obligations at March 31, 2018 did not differ materially from those reported in our 2017 Form 10-K. 

Liquidity Option Agreement

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

The carrying value of the Liquidity Option Agreement, which is a component of “Other long-term liabilities” on our Unaudited Condensed Consolidated Balance Sheet, was $341.4 million and $333.9 million at March 31, 2018 and December 31, 2017, respectively.  The fair value of the Liquidity Option, at any measurement date, represents the present value of estimated federal and state income tax payments that we believe a market participant would incur on the future taxable income of OTA. We expect that OTA’s taxable income would, in turn, be based on an allocation of our partnership’s taxable income to the common units then held by OTA and reflect any tax planning we believe could be employed. Our valuation estimate for the Liquidity Option at March 31, 2018 is based on several inputs that are not observable in the market (i.e., Level 3 inputs) such as the following:

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

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

 OTA’s ownership interest in Enterprise common units is assumed to be diluted over time in connection with Enterprise’s issuance of equity for general company reasons.  For purposes of the valuation at March 31, 2018, we used ownership interests ranging from 1.8% to 2.5%;

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

 A discount rate of 7.6% based on our weighted-average cost of capital at March 31, 2018.

40

ENTERPRISE PRODUCTS PARTNERS L.P.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

Furthermore, our valuation estimate incorporates probability-weighted scenarios reflecting the likelihood that M&B may elect to divest a portion of the Enterprise common units held by OTA prior to exercise of the option.  At March 31, 2018, based on these scenarios, we expect that OTA would own approximately 90.5% 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 had 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, 2018 would have increased by $35.6 million.

Changes in the fair value of the Liquidity Option are recognized in earnings as a component of other income (expense) on our Unaudited Condensed Statements of Consolidated Operations.  Results for the three months ended March 31, 2018 and 2017 include $7.5 million and $5.5 million, respectively, of aggregate non-cash expense attributable to accretion and changes in management estimates regarding inputs to the valuation model.

Overview of Business

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

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

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

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

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

Significant Recent Developments

Enterprise and Energy Transfer form Joint Venture to Restore Service on Old Ocean Pipeline

In May 2018, we announced the formation of a 50/50 joint venture with Energy Transfer Partners, L.P. (“Energy Transfer”) to resume service on the Old Ocean natural gas pipeline owned by Energy Transfer.  The 24-inch diameter Old Ocean Pipeline originates in Maypearl, Texas in Ellis County and extends south approximately 240 miles to Sweeny, Texas in Brazoria County.  The Old Ocean Pipeline is expected to resume service in the second quarter of 2018 and provide natural gas transportation capacity of approximately 160 MMcf/d.  The resumption of service on the Old Ocean Pipeline will provide producers with additional takeaway capacity from the growing Delaware Basin and Midland Basin.

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

Proposed Expansions of our Front Range Pipeline and Texas Express Pipelines

In May 2018, we announced the start of a binding open commitment period to determine shipper interest in proposed expansions of our Front Range Pipeline (“Front Range”) and Texas Express Pipeline (“Texas Express”).  The binding open commitment periods extend to June 4, 2018.

The proposed expansions are designed to facilitate growing production of NGLs from domestic shale basins, including the Denver-Julesburg (“DJ”) Basin in Colorado, by providing DJ Basin producers with flow assurance and greater access to the Gulf Coast markets.  If constructed, the expansions would increase the transportation capacity of Front Range and Texas Express by 100 MBPD and 90 MBPD, respectively.  The expansion projects, which are subject to receiving sufficient commitments from shippers, would begin service during the second quarter of 2019.

Enterprise Begins Service at Orla Natural Gas Processing Plant in the Delaware Basin

In May 2018, we announced the start of commercial operations for the initial processing train (“Orla I”) at our new cryogenic natural gas processing facility located near Orla, Texas in Reeves County.  The Orla I plant has a nameplate natural gas processing capacity of 300 MMcf/d and is capable of extracting in excess of 40 MBPD of NGLs. We expect that the second and third processing trains at the facility (Orla II and Orla III) will be placed into service in the fourth quarter of 2018 and third quarter of 2019, respectively. Once Orla III is completed, the Orla facility is expected to have up to 1 Bcf/d of aggregate natural gas processing capacity and the ability to extract up to 150 MBPD of NGLs.  We own and operate the Orla facility.

In conjunction with the start-up of Orla I, we placed into service approximately 70 miles of natural gas pipelines that connect the Orla facility to our Texas Intrastate System.   We also placed into service a 30-mile extension of our NGL system that will provide producers at the Orla facility with NGL takeaway capacity and direct access to our integrated network of downstream NGL assets.

Enterprise Expands Marine Terminal on the Houston Ship Channel

In April 2018, we purchased a 65-acre waterfront site located on the Houston Ship Channel that will serve as the next phase of expansion at our Enterprise Hydrocarbons Terminal (“EHT”).  Located immediately to the east of EHT, the property features two existing docks, dredging infrastructure that will be utilized for maintenance and dock expansion at the site, and land that we plan to use for expanding our marine terminal capabilities at EHT.  Our future plans for the site include the construction of at least two additional deepwater docks capable of accommodating Suezmax vessels.

Expected Sale of 20% Ownership Interest in Midland-to-ECHO Pipeline

In April 2018, an affiliate of Western Gas Partners, LP (“Western”) exercised its option to acquire a noncontrolling 20% ownership interest in the Midland-to-ECHO crude oil pipeline and its related commercial activities for approximately $200 million. This transaction is expected to close in mid-2018 subject to the execution of definitive agreements.

At closing, Western will be credited for 20% of the pipeline’s earnings since it was placed into service in November 2017. Our expected obligation to Western related to the pipeline’s earnings totaled $35.9 million at March 31, 2018, which is a component of other current liabilities on our Unaudited Condensed Consolidated Balance Sheet.  As a result of this arrangement, we report the pipeline’s volumes on a net basis reflecting our expected 80% ownership.   Western is also expected to proportionately share in the results of our limited commercial activities attributable to the pipeline.

Enterprise Begins Full Service on Midland-to-ECHO Pipeline

In April 2018, we announced that the 416-mile Midland-to-Sealy segment of our Midland-to-ECHO Pipeline is now in full service with an expanded transportation capacity of 540 MBPD.  The completed pipeline provides Permian Basin producers with the ability to transport multiple grades of crude oil, including West Texas Intermediate (“WTI”), Light WTI, West Texas Sour and condensate, to Gulf Coast markets.

By the end of May 2018, we expect to increase the pipeline’s capacity to 575 MBPD with the completion of incremental tankage and additional infrastructure as well as operating enhancements.  In addition, we expect to complete a 143-mile pipeline system that will deliver more than 300 MBPD of crude oil and condensate from the Delaware Basin to our Midland Terminal.   This project is scheduled for completion in July 2018 and is supported by long-term commitments from shippers.

Acquisition of Remaining 50% Ownership Interest in Waha Gas Plant

In March 2018, we acquired the remaining 50% member interest in our Delaware Basin Gas Processing LLC (“Delaware Processing”) joint venture for $153.6 million in cash.  Delaware Processing owns a cryogenic natural gas processing facility (our “Waha” gas plant) having a capacity of 150 MMcf/d.  The Waha plant is located in Reeves County, Texas and entered service in August 2016. The acquired business serves growing production of NGL-rich natural gas from the Delaware Basin in West Texas and southern New Mexico. For information regarding this acquisition, see Note 11 of the Notes to Unaudited Condensed Consolidated Financial Statements included under Part I, Item 1 of this quarterly report.

Plans to Build Ethylene Export Dock and Related Projects

In January 2018, we announced the formation of a new 50/50 joint venture with Navigator Holdings Ltd. (“Navigator”) to construct, own and operate an ethylene export facility along the U.S. Gulf Coast.  The export facility is expected to have the capacity to export approximately one million tons of ethylene per year, with loading rates of approximately 1,000 tons per hour.  In addition, the facility is expected to include refrigerated storage for 30,000 tons of ethylene.   The project, which is underwritten by long-term contracts with customers, is expected to be completed in the fourth quarter of 2019.  The location and final investment decisions for the terminal are subject to reaching acceptable arrangements with local taxing authorities.

Enterprise to Expand Butane Isomerization Facility

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

Fluctuations in our consolidated revenues and cost of sales amounts are explained in large part by changes in energy commodity prices.  Energy commodity prices fluctuate for a variety of reasons, including supply and demand imbalances and geopolitical tensions.  The weighted-average indicative market price for NGLs was $0.77 per gallon in the first quarter of 2018 versus $0.66 per gallon during the first quarter of 2017.

53

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

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

Consolidated Income Statement Highlights

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

Revenues

Total revenues for the first quarter of 2018 increased $1.98 billion when compared to the first quarter of 2017 primarily due to a $1.75 billion increase in marketing revenues.  Revenues from the marketing of crude oil increased $1.72 billion quarter-to-quarter primarily due to higher sales volumes, which accounted for a $1.38 billion increase, and higher sales prices, which accounted for an additional $345.4 million increase. Crude oil marketing sales volumes increased quarter-to-quarter as we seek to optimize the utilization of our crude oil pipelines and related assets (e.g., the Midland-to-ECHO Pipeline) and capitalize on pricing opportunities attributable to significant increases in crude oil production in West Texas and the Permian Basin.  Revenues from the marketing of petrochemicals increased $70.3 million quarter-to-quarter primarily due to higher prices for propylene.  Revenues from the marketing of NGLs and related products decreased a net $71.8 million quarter-to-quarter primarily due to lower sales volumes, which accounted for a $556.5 million decrease, partially offset by a $484.7 million increase due to higher sales prices.

Revenues from midstream services for the first quarter of 2018 increased $232.6 million when compared to the first quarter of 2017.  As a result of adopting ASC 606, we recognized $113.8 million of revenues during the first quarter of 2018 in connection with the receipt of non-cash consideration (in the form of equity NGLs) for providing natural gas processing services. Midstream service revenues from our pipeline assets increased $101.3 million quarter-to-quarter primarily due to strong demand for transportation services in Texas and on the Appalachia-to-Texas Express (“ATEX”) pipeline. Propylene fractionation revenues increased $14.0 million quarter-to-quarter primarily due to higher fees.

Operating costs and expenses

Total operating costs and expenses for the first quarter of 2018 increased $1.89 billion when compared to the first quarter of 2017 primarily due to a $1.80 billion increase in cost of sales.  The cost of sales associated with our marketing of crude oil increased $1.76 billion quarter-to-quarter primarily due to higher sales volumes, which accounted for a $1.31 billion increase, and higher purchase prices, which accounted for an additional $447.4 million increase. The cost of sales associated with our NGL marketing activities increased $136.8 million quarter-to-quarter primarily due to the sale of NGLs received in connection with providing natural gas processing services (i.e., equity NGLs).

Other operating costs and expenses for the first quarter of 2018 increased a net $77.2 million when compared to the first quarter of 2017.  Employee compensation, power and maintenance costs increased a combined $38.4 million quarter-to-quarter. Depreciation, amortization and accretion expense increased $18.1 million quarter-to-quarter primarily due to assets we constructed and placed into service since the first quarter of 2017 (e.g., our Midland-to-ECHO pipeline and the assets we acquired from Azure Midstream Partners, LP and its operating subsidiaries (collectively, “Azure”)).  Non-cash asset impairment charges decreased $10.3 million quarter-to-quarter.  Our non-cash asset impairment charges for the first quarter of 2017 primarily related to the write-down of materials held as spare parts.

General and administrative costs

General and administrative costs for the first quarter of 2018 increased a net $2.6 million when compared to the first quarter of 2017.  Employee compensation and legal-related costs increased a combined $7.3 million quarter-to-quarter, partially offset by a $4.6 million quarter-to-quarter decrease in regulatory costs.

54

Equity in income of unconsolidated affiliates

Equity income from our unconsolidated affiliates for the first quarter of 2018 increased $20.9 million when compared to the same period in 2017 primarily due to an increase in earnings from our investments in crude oil pipelines.

Operating income

Operating income for the first quarter of 2018 increased $106.9 million 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

Interest expense for the first quarter of 2018 increased $2.8 million when compared to the first quarter of 2017.  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,
	2018			2017
Interest charged on debt principal outstanding	$	292.0		$	272.9
Impact of interest rate hedging program, including related amortization (1)		3.7			8.7
Interest costs capitalized in connection with construction projects (2)		(58.2	)		(39.6	)
Other (3)		14.6			7.3
Total	$	252.1		$	249.3
(1)   Amount presented for first quarter of 2018 includes $7.2 million of swaption premium income. (2)   We capitalize interest costs incurred on funds used to construct property, plant and equipment while the asset is in its construction phase. Capitalized interest amounts become part of the historical cost of an asset and are charged to earnings (as a component of depreciation expense) on a straight-line basis over the estimated useful life of the asset once the asset enters its intended service. When capitalized interest is recorded, it reduces interest expense from what it would be otherwise. Capitalized interest amounts fluctuate based on the timing of when projects are placed into service, our capital spending levels and the interest rates charged on borrowings. (3)   Primarily reflects facility commitment fees charged in connection with our revolving credit facilities and amortization 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 B.

Interest charged on debt principal outstanding, which is the primary driver of interest expense, increased $19.1 million quarter-to-quarter primarily due to increased debt principal amounts outstanding during the first quarter of 2018, which accounted for a $17.8 million increase, and the effect of higher overall interest rates during the first quarter of 2018, which accounted for a $1.3 million increase.  Our weighted-average debt principal balance for the first quarter of 2018 was $25.24 billion compared to $23.67 billion for the first quarter of 2017.

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

Gain on step acquisition of unconsolidated affiliate

We recognized a gain of $37.0 million related to the step acquisition of Delaware Processing.  For information regarding this acquisition, see Note 11 of the Notes to Unaudited Condensed Consolidated Financial Statements included under Part I, Item 1 of this quarterly report.

Income taxes

Income taxes primarily reflect our state tax obligations under the Revised Texas Franchise Tax.  Our provision for income taxes for the first quarter of 2018 decreased $0.9 million when compared to the same period in 2017.

55

Total Gross Operating Margin

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

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

	For the Three Months Ended March 31,
	2018		2017
Gross operating margin by segment:
NGL Pipelines & Services	$	884.9	$	856.0
Crude Oil Pipelines & Services		220.0		264.6
Natural Gas Pipelines & Services		197.9		170.9
Petrochemical & Refined Products Services		271.9		181.8
Total segment gross operating margin (1)		1,574.7		1,473.3
Net adjustment for shipper make-up rights		11.5		(4.2	)
Total gross operating margin (non-GAAP)	$	1,586.2	$	1,469.1
(1)   Within the context of this table, total segment gross operating margin represents a subtotal and corresponds to measures similarly titled within our business segment disclosures found in Note 10 of the Notes to Unaudited Condensed Consolidated Financial Statements included under Part I, Item 1 of this quarterly report.

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

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

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

	For the Three Months Ended March 31,
	2018			2017
Operating income (GAAP)	$	1,138.5		$	1,031.6
Adjustments to reconcile operating income to total gross operating margin:
Add depreciation, amortization and accretion expense in operating costs and expenses		394.3			376.2
Add asset impairment and related charges in operating costs and expenses		0.9			11.2
Subtract net gains attributable to asset sales in operating costs and expenses		(0.5	)		(0.3	)
Add general and administrative costs		53.0			50.4
Total gross operating margin (non-GAAP)	$	1,586.2		$	1,469.1

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.

56

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

Business Segment Highlights

The following discussions of gross operating margin by segment are based on amounts actually recognized in our Unaudited Condensed Statements of Consolidated Operations for the first quarters of 2018 and 2017.

NGL Pipelines & Services

The following table presents segment gross operating margin and selected volumetric data for the NGL Pipelines & Services segment for the periods indicated (dollars in millions, volumes as noted):

NGL fractionation volumes (MBPD)		824		799
(1)   Represents the NGL volumes we earn and take title to in connection with our processing activities. (2)   Volumes reported correspond to the revenue streams earned by our gas plants.

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 2018 decreased a net $29.4 million when compared to the first quarter of 2017.

Gross operating margin from our NGL marketing activities decreased a net $62.9 million quarter-to-quarter primarily due to lower sales volumes, which accounted for a $93.7 million decrease, partially offset by a $30.7 million increase due to higher sales margins.  The results from marketing strategies to optimize our storage and export dock assets decreased a combined $72.3 million quarter-to-quarter, partially offset by a $19.6 million increase in earnings from the optimization of our transportation assets.

Gross operating margin from our natural gas processing plants increased $33.5 million quarter-to-quarter primarily due to higher average processing margins (including the impact of hedging activities) in the first quarter of 2018 at our Rockies and South Texas plants.  In addition, higher equity NGL production in the first quarter of 2018 at our Meeker and Pioneer plants accounted for a $5.4 million quarter-to-quarter increase in gross operating margin. These increases were partially offset by the impact of lower fee-based processing volumes in the first quarter of 2018 at our Louisiana and South Texas plants, which accounted for a combined $4.5 million quarter-to-quarter decrease in gross operating margin.

NGL pipelines, storage and terminals.  Gross operating margin from NGL pipelines, storage and terminal assets for the first quarter of 2018 increased a net $54.4 million when compared to the first quarter of 2017.

Gross operating margin from our Seminole, Chaparral and affiliated pipelines increased a combined $22.6 million quarter-to-quarter primarily due to higher average transportation fees, which accounted for a $12.7 million increase, and higher transportation volumes, which accounted for an additional $8.3 million increase.  On a combined basis, NGL transportation volumes on these pipelines increased 37 MBPD quarter-to-quarter.

Gross operating margin from ATEX increased $18.6 million quarter-to-quarter primarily due to higher transportation volumes, which increased 32 MBPD in the first quarter of 2018.

57

Gross operating margin from our equity investment in the Texas Express Pipeline increased $3.2 million quarter-to-quarter primarily due to contractual increases in committed volumes from anchor shippers.

Gross operating margin from our Dixie Pipeline and related terminals increased a combined $1.5 million quarter-to-quarter primarily due to higher transportation volumes of 21 MBPD in the first quarter of 2018, which accounted for a $4.4 million increase, partially offset by higher operating costs, which accounted for a $3.1 million quarter-to-quarter decrease.

Gross operating margin from our South Texas NGL Pipeline System decreased $7.8 million quarter-to-quarter primarily due to lower transportation volumes, which accounted for a $4.7 million decrease, and lower storage revenues, which accounted for an additional $2.1 million decrease.  Transportation volumes for the South Texas NGL Pipeline System decreased 39 MBPD quarter-to-quarter.

Gross operating margin from our storage complexes in South Louisiana and Mont Belvieu increased a combined $8.9 million quarter-to-quarter primarily due to increased storage and storage-related activity revenues.

Gross operating margin from our Morgan’s Point Ethane Export Terminal increased $12.0 million quarter-to-quarter primarily due to higher ethane loading volumes of 75 MBPD.

Gross operating margin from EHT decreased $11.0 million quarter-to-quarter primarily due to lower marine terminal volumes of 68 MBPD, which accounted for a $9.7 million decrease, and higher maintenance and other operating costs, which accounted for an additional $1.6 million decrease.

NGL fractionation.  Gross operating margin from NGL fractionation for the first quarter of 2018 increased a net $3.9 million when compared to the first quarter of 2017 primarily due to higher product blending revenues at our Mont Belvieu and Hobbs NGL fractionators.   NGL fractionation volumes at our Mont Belvieu facility increased 25 MBPD, net to our interest.

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,
	2018		2017
Segment gross operating margin	$	220.0	$	264.6
Selected volumetric data:
Crude oil pipeline transportation volumes (MBPD)		2,034		1,356
Crude oil marine terminal volumes (MBPD)		634		475

Gross operating margin from our Crude Oil Pipelines & Services segment for the first quarter of 2018 decreased a net $44.6 million when compared to the first quarter of 2017.

Gross operating margin from our South Texas Crude Oil Pipeline System increased a net $39.8 million quarter-to-quarter primarily due to higher firm capacity reservation fees associated with the Midland-to-ECHO Pipeline, which accounted for a $24.0 million increase, and higher transportation volumes, which accounted for an additional $21.8 million increase, partially offset by lower average transportation fees, which accounted for a $7.2 million decrease. Crude oil transportation volumes for this system increased 65 MBPD quarter-to-quarter.  Gross operating margin from our West Texas System and equity investment in the Eagle Ford Crude Oil Pipeline System increased a combined $6.8 million quarter-to-quarter primarily due to higher crude oil transportation volumes from the Permian Basin.  Crude oil transportation volumes on the Eagle Ford Crude Oil Pipeline System increased 91 MBPD quarter-to-quarter (net to our interest) and 6 MBPD on the West Texas System.

58

Gross operating margin from our ECHO and Midland terminals increased a net $9.7 million quarter-to-quarter primarily due to higher terminaling volumes, which accounted for a $7.5 million increase, higher average terminaling fees, which accounted for an additional $3.1 million increase, partially offset by higher maintenance and other operating costs, which accounted for a $1.0 million decrease. Gross operating margin from our EHT increased $8.1 million quarter-to-quarter primarily due to higher volumes of 181 MBPD.

Gross operating margin from our crude oil marketing activities, excluding those attributable to our commercial activities on the Midland-to-ECHO Pipeline (see below), decreased $46.1 million quarter-to-quarter primarily due to mark-to-market losses in the first quarter of 2018 in connection with the widening of crude oil commodity price differentials between the Midland, Texas and Cushing, Oklahoma markets.

Midland-to-ECHO Pipeline and related marketing activities.  Gross operating margin from our Midland-to-ECHO Pipeline and related marketing activities was a combined loss of $60.2 million for the first quarter of 2018.  Transportation volumes on the pipeline, which entered into limited commercial service during the fourth quarter of 2017 and full service in April 2018, averaged 398 MBPD during the first quarter (net to our interest).

Gross operating margin for this business during the first quarter of 2018 includes $114.0 million of non-cash mark-to-market losses associated with the hedging of crude oil commodity price differentials (basis spreads) between the Midland and Houston area markets.  These hedges, which were entered into throughout 2017, served to lock in an average $2.59 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 in 2020.  The mark-to-market losses recognized during the first quarter of 2018 were due to the widening of the basis spreads between Midland and Houston to an average of $5.99 per barrel through 2020 (as of March 31, 2018).

Basis swaps, in all but very limited circumstances, do not qualify for cash flow hedge accounting despite being highly effective at hedging the price risk inherent in the underlying physical transactions.  The volume hedged throughout the remainder of 2018 through 2020 varies from quarter-to-quarter and year-to-year, however the hedge levels generally correspond to pipeline capacity currently expected to be available to us during the first three years of the pipeline’s operations as customer commitment volumes ramp up to peak levels.

If the basis spreads underlying these hedges widen further, we would be exposed to additional temporary non-cash mark-to-market losses.  Conversely, if basis spreads narrow in the future reverting back towards or below the average $2.59 per barrel spread we originally locked in, then we would recognize temporary non-cash mark-to-market gains in future periods.  When the forecasted physical receipts and deliveries of crude oil ultimately occur in the future, we will realize a physical gross margin at then prevailing commodity price spreads; however the realized settlement of the associated financial hedges will convert that physical margin to the average $2.59 per barrel spread of the financial hedges.  At that time, the unrealized mark-to-market losses recognized in the first quarter of 2018 and in future periods until the physical deliveries occur will be reversed, thus eliminating their impact to cumulative earnings recognized over the entire life-to-date period of the hedge.

At March 31, 2018, approximately 47% of the Midland-to-EHCO Pipeline’s uncommitted capacity available to us through 2020 remains unhedged, thus providing us with potential upside to widening or downside to narrowing market spreads.

The basis spread between the Midland and Houston markets has continued to widen during the second quarter of 2018.  For information regarding the impact of these higher spreads on our crude oil marketing hedging portfolio, see Item 3, Quantitative and Qualitative Disclosures about Market Risk, within this Part I, Item 2.  For general information regarding our derivative instruments and hedging activities, see Note 14 of the Notes to Unaudited Condensed Consolidated Financial Statements included under Part I, Item 1 of this quarterly report.

Gross operating margin from the Midland-to-ECHO Pipeline for the first quarter of 2018 was also reduced by $24.2 million in connection with the expected allocation of pipeline earnings to Western upon closing of their acquisition of a 20% ownership interest in the pipeline.  For additional information regarding this pending transaction, see “Significant Recent Developments” within this Part I, Item 2.

Issuance of $2.0 Billion of Senior Notes and $700 Million of Junior Subordinated Notes in February 2018

In February 2018, EPO issued $2.7 billion aggregate principal amount of notes comprised of (i) $750 million principal amount of senior notes due February 15, 2021 (“Senior Notes TT”), (ii) $1.25 billion principal amount of senior notes due February 15, 2048 (“Senior Notes UU”) and (iii) $700 million principal amount of junior subordinated notes due February 15, 2078 (“Junior Subordinated Notes F”).

Net proceeds from these offerings were used by EPO for the temporary repayment of amounts outstanding under its commercial paper program, general company purposes, and the redemption of all $682.7 million outstanding aggregate principal amount of its 7.034% Junior Subordinated Notes B.

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

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

Redemption of Junior Subordinated Notes B

On March 5, 2018, EPO redeemed all of the $682.7 million outstanding aggregate principal amount of its Junior Subordinated Notes B at a price equal to 100% of the principal amount of the notes being redeemed, plus all accrued and unpaid interest thereon to, but not including, the redemption date. The redemption of the 7.034% Junior Subordinated Notes B and the issuance of the 5.375% Junior Subordinated Notes F will result in annual interest savings to EPO of approximately $11.3 million.

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

Issuance of Common Units

The following table summarizes the issuance of common units in connection with our distribution reinvestment plan (“DRIP”) and employee unit purchase plan (“EUPP”) for the three months ended March 31, 2018 (dollars in millions, number of units issued as shown):

	Number of Common Units Issued		Net Cash Proceeds Received
Common units issued in connection with DRIP and EUPP		6,642,286	$	177.0

62

DRIP and EUPP

We have a registration statement on file with the SEC in connection with our DRIP.  The DRIP provides unitholders of record and beneficial owners of our common units a voluntary means by which they can increase the number of our common units they own by reinvesting the quarterly cash distributions they receive from us into the purchase of additional new common units.  After taking into account the number of common units issued under the DRIP through March 31, 2018, we have the capacity to issue an additional 74,207,487 common units under this plan.

Privately held affiliates of EPCO purchased $100 million of our common units through the DRIP in connection with the distribution paid on February 7, 2018.

In addition to the DRIP, we have registration statements on file with the SEC in connection with our EUPP.  After taking into account the number of common units issued under the EUPP through March 31, 2018, we have the capacity to issue an additional 5,628,178 common units under this plan.

ATM Program

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

Use of Proceeds

The net cash proceeds we received from the issuance of common units during the three months ended March 31, 2018 were used to temporarily reduce amounts outstanding under EPO’s commercial paper program and for general company purposes.

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

Restricted Cash

Restricted cash represents amounts held in segregated bank accounts by our clearing brokers as margin in support of our commodity derivative instruments portfolio and related physical purchases and sales of natural gas, NGLs, crude oil and refined products.  At March 31, 2018 and December 31, 2017, our restricted cash amounts were $113.5 million and $65.2 million, respectively.

Additional cash may be restricted to maintain our commodity derivative instruments portfolio as prices fluctuate or margin requirements change.  For information regarding our derivative instruments and hedging activities, see Note 14 of the Notes to Unaudited Condensed Consolidated Financial Statements included under Part I, Item 1 of this quarterly report.  In addition, see Item 3, Quantitative and Qualitative Disclosures about Market Risk, within this Part I, Item 2.

Credit Ratings

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

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

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,
	2018		2017
Net cash flows provided by operating activities	$	1,233.6	$	875.6
Cash used in investing activities		1,119.1		444.0
Cash provided by (used in) financing activities		30.8		(742.1	)

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

Comparison of Three Months Ended March 31, 2018 with Three Months Ended March 31, 2017

The following information highlights significant quarter-to-quarter fluctuations in our consolidated cash flow amounts:

Operating activities.  Net cash flows provided by operating activities for the first quarter of 2018 increased $358.0 million when compared to the first quarter of 2017.  The increase in cash provided by operating activities was primarily due to:

§ a $255.3 million increase in cash resulting from higher partnership earnings in the first quarter of 2018 compared to the same period in 2017 (after adjusting our $140.5 million quarter-to-quarter increase in net income for changes in the non-cash items identified on our Unaudited Condensed Statements of Consolidated Cash Flows);

§ a $17.0 million quarter-to-quarter increase in cash distributions received on earnings from unconsolidated affiliates primarily due to our investments in crude oil pipeline joint ventures; and

§ an $85.7 million quarter-to-quarter increase in cash primarily due to the timing of cash receipts and payments related to operations.

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

Investing activities.  Cash used for investing activities in the first quarter of 2018 increased $675.1 million when compared to the same period in 2017 primarily due to:

§ a $516.1 million quarter-to-quarter increase in capital spending for consolidated property, plant and equipment (see “Capital Spending” within this Part I, Item 2 for additional information regarding our capital spending program);

64

§ a $133.8 million quarter-to-quarter increase in cash used for business combinations, net of cash received.  During the first quarter of 2018, net cash used for business combinations was $149.8 million, which was related to the acquisition of the remaining member interest of Delaware Processing.  During the same period in 2017, a $16.0 million deposit was paid for the acquisition of Azure, which was completed in April 2017; and

§ a $24.2 million quarter-to-quarter increase in investments in unconsolidated affiliates.

Financing activities.  Cash provided by financing activities for the first quarter of 2018 was $30.8 million compared to cash used in financing activities of $742.1 million for the first quarter of 2017.  The $772.9 million quarter-to-quarter change in cash flow from financing activities was primarily due to:

§ a $2.02 billion net cash inflow attributable to the issuance of $2.7 billion in principal amount of senior and junior subordinated notes offset by the repayment of $682.7 million in principal amount of Junior Subordinated Notes B during the first quarter of 2018 compared to no such issuances or repayments during the first quarter of 2017.   Net repayments under EPO’s commercial paper program increased $894.7 million quarter-to-quarter; partially offset by

§ a $271.8 million quarter-to-quarter decrease in net cash proceeds from the issuance of common units.  We issued an aggregate 6,642,286 common units, which generated $177.0 million of net cash proceeds, in connection with our DRIP and EUPP during the first quarter of 2018.  This compares to an aggregate 16,305,930 common units we issued in connection with our ATM, DRIP and EUPP during the first quarter of 2017, which collectively generated $448.8 million of net cash proceeds; and

§ a $49.5 million quarter-to-quarter increase in cash distributions paid to limited partners during the first quarter of 2018 when compared to the first quarter of 2017.  The increase in cash distributions is due to increases in both the number of distribution-bearing common units outstanding and the quarterly cash distribution rates per unit.

Cash Distributions to Limited Partners

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

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

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

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

Capital Spending

We have approximately $5.3 billion of growth capital projects scheduled to be completed by the end of 2019.  These projects include:

§ our ninth NGL fractionator in Mont Belvieu, Texas (second quarter of 2018);

§ the completion of joint venture-owned dock infrastructure in Corpus Christi designed to accommodate crude oil volumes (third quarter of 2018);

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

§ expansions of our Front Range and Texas Express NGL pipelines (second and fourth quarters of 2019, respectively);

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

§ the ethylene export terminal (fourth quarter of 2019).

Our PDH facility recently completed its commissioning phase and was placed into service in April 2018.   In addition, the first processing train at our Orla natural gas processing facility (“Orla I”) entered service in May 2018.

Based on information currently available, we expect our total growth capital spending for 2018 to approximate $3.2 billion to $3.4 billion, which includes the approximate $150 million we spent in March 2018 to acquire the remaining equity interest in Delaware Processing.  Further, we expect our sustaining capital expenditures for 2018 to approximate $315 million, of which $73 million was spent in the first quarter of 2018.

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

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

67

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

	For the Three Months Ended March 31,
	2018		2017
Capital spending for property, plant and equipment: (1)
Growth capital projects (2)	$	873.3	$	379.6
Sustaining capital projects (3)		73.2		50.8
Total	$	946.5	$	430.4
Cash used for business combinations, net (4)	$	149.8	$	16.0
Investments in unconsolidated affiliates	$	37.9	$	13.7
(1)   Growth and sustaining capital amounts presented in the table above are presented on a cash basis. (2)   Growth capital projects either (a) result in new sources of cash flow due to enhancements of or additions to existing assets (e.g., additional revenue streams, cost savings resulting from debottlenecking of a facility, etc.) or (b) expand our asset base through construction of new facilities that will generate additional revenue streams and cash flows. (3)   Sustaining capital expenditures are capital expenditures (as defined by GAAP) resulting from improvements to existing assets. Such expenditures serve to maintain existing operations but do not generate additional revenues or result in significant cost savings. (4)   Amount presented for the first quarter of 2018 represents the acquisition of the remaining 50% ownership interest in our Delaware Processing joint venture, which closed on March 29, 2018.

Fluctuations in our spending for growth capital projects and investments in unconsolidated affiliates are explained in large part by increases or decreases in spending on major expansion projects.  Our most significant growth capital expenditures for the three months ended March 31, 2018 involved projects to support crude oil, natural gas and NGL production from the Permian Basin and export activities at our Gulf Coast terminal.  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, 2018 with Three Months Ended March 31, 2017

Total capital spending increased $674.1 million quarter-to-quarter primarily due to increased cash used for growth capital projects, which accounted for a $493.7 million increase, and higher cash used for business combinations, which accounted for an additional $133.8 million increase.  Of the quarter-to-quarter increase in capital spending, the significant elements are as follows:

§ Growth capital spending for projects to support Permian Basin production increased $252.5 million quarter-to-quarter.  We are in various stages of completion on multiple projects to support crude oil, natural gas and NGL production in the Permian Basin, including our Orla natural gas processing facility and related pipelines and the Shin Oak NGL Pipeline.

§ Growth capital spending for projects to expand and support export activities at EHT increased $154.3 million quarter-to-quarter.

§ Growth capital spending at our Mont Belvieu complex increased $68.0 million quarter-to-quarter primarily due to increased capital spending for our iBDH plant, which accounted for a $67.2 million increase, and our ninth NGL fractionator, which accounted for an additional $34.0 million increase, partially offset by lower growth capital spending at our PDH facility, which accounted for a $27.7 million decrease.  The ninth NGL fractionator, which resumed construction in March 2017 in anticipation of increased NGL production from the Permian Basin, is expected to be completed during the second quarter of 2018.

§ Net cash used for business combinations increased $133.8 million quarter-to-quarter primarily due to our acquisition of the remaining 50% member interest in Delaware Processing for $149.8 million in March 2018.

Pipeline Integrity Program

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

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

	For the Three Months Ended March 31,
	2018		2017
Recognized in operating costs and expenses	$	17.0	$	15.3
Reflected as a component of sustaining capital expenditures		7.7		8.2
Total	$	24.7	$	23.5

Critical Accounting Policies and Estimates

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

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

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

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

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

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

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

Other Items

Contractual Obligations

Our consolidated principal debt obligations at March 31, 2018 were approximately $25.62 billion compared to $24.78 billion at December 31, 2017.  For information regarding the scheduled maturities of such debt, see “Liquidity and Capital Resources – Consolidated Debt” within this Part I, Item 2.  See Note 7 of the Notes to Unaudited Condensed Consolidated Financial Statements under Part I, Item 1 of this quarterly report for additional information regarding our consolidated debt obligations.

Off-Balance Sheet Arrangements

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

Recent Accounting Developments

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

Related Party Transactions

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

Item 3.    Quantitative and Qualitative Disclosures About Market Risk.

General

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

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

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

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

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

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

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

Commodity Hedging Activities

The prices of natural gas, NGLs, crude oil, petrochemicals and refined products are subject to fluctuations in response to changes in supply and demand, market conditions and a variety of additional factors that are beyond our control.  In order to manage such price risks, we enter into commodity derivative instruments such as physical forward contracts, futures contracts, fixed-for-float swaps, basis swaps and option contracts.  The following table summarizes our portfolio of commodity derivative instruments outstanding at March 31, 2018 (volume measures as noted):

	Volume (1)		Accounting
Derivative Purpose	Current (2)	Long-Term (2)	Treatment
Derivatives designated as hedging instruments:
Natural gas processing:
Forecasted natural gas purchases for plant thermal reduction (Bcf)	2.1	n/a	Cash flow hedge

Crude oil marketing:
Forecasted purchases of crude oil (MMBbls)	4.0	6.5	Cash flow hedge
Forecasted sales of crude oil (MMBbls)	8.4	6.5	Cash flow hedge
Propylene marketing:
Forecasted purchases of NGLs for propylene marketing activities (MMBbls)	0.8	n/a	Cash flow hedge
Forecasted sales of NGLs for propylene marketing activities (MMBbls)	0.8	n/a	Cash flow hedge
Derivatives not designated as hedging instruments:
Natural gas risk management activities (Bcf) (3,4)	92.0	5.6	Mark-to-market
NGL risk management activities (MMBbls) (4)	0.2	n/a	Mark-to-market
Refined products risk management activities (MMBbls) (4)	2.3	n/a	Mark-to-market
Crude oil risk management activities (MMBbls) (4)	91.3	23.8	Mark-to-market
(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 2018 and December 2020, respectively. (3)   Current and long-term volumes include 42.4 Bcf and 3.0 Bcf, respectively, 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, 2018, our predominant commodity hedging strategies consisted of (i) hedging anticipated future purchases and sales of commodity products associated with transportation, storage and blending activities, (ii) hedging natural gas processing margins and (iii) hedging the fair value of commodity products held in inventory.  

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

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

71

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

As noted in our discussion of results for the Crude Oil Pipelines & Services segment (Midland-to-ECHO Pipeline and related commercial activities), we entered into hedges of the crude oil commodity price differentials between the Midland and Houston Texas areas. The mark-to-market derivative liability for these instruments increased from $42.4 million at December 31, 2017 to $156.4 million at March 31, 2018, which resulted in a $114.0 million decrease in the fair value of the crude oil marketing portfolio for the first quarter of 2018.  The mark-to-market derivative liability for these instruments increased to $481.3 million at May 3, 2018 primarily due to a further widening of the crude oil commodity price differentials (basis spreads) between the Midland and Houston markets since March 31, 2018.  Excluding those hedges that settle through June 30, 2018 and assuming no further change in the basis spreads between May 3, 2018 and June 30, 2018, the impact to earnings would be an approximate $309.6 million non-cash, mark-to-market loss recognized in the second quarter of 2018. These losses are temporary such that when the hedged transactions occur in the future, the unrealized mark-to-market losses will reverse and be realized against the expected gains on the physical transactions.

Additional cash may be posted to maintain our commodity derivative instruments portfolio as prices fluctuate or margin requirements change.  Our restricted cash balance increased from $113.5 million at March 31, 2018 to $253.2 million at May 3, 2018.  In addition, we have posted $221.7 million of cash and $52.9 million under stand-by letters of credit in connection with margin requirements on the Chicago Mercantile Exchange through May 3, 2018. The increase in restricted cash and other cash postings since March 31, 2018 is primarily due to changes in the fair value of our crude oil marketing transportation hedges.

72

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.

With respect to the tabular data below, each portfolio’s estimated economic value at a given date is based on a number of factors, including the number and types of derivatives outstanding at that date, the notional value of the swaps and associated interest rates.

Interest rate swaps exchange the stated interest rate paid on a notional amount of existing debt for the fixed or floating interest rate stipulated in the derivative instrument.  The following table summarizes our portfolio of interest rate swaps at March 31, 2018 (dollars in millions):

Hedged Transaction	Number and Type  of Derivatives Outstanding	Notional Amount		Period of Hedge	Rate Swap	Accounting Treatment
Senior Notes OO	10 fixed-to-floating swaps	$	750.0	5/2015 to 5/2018	1.65% to 2.27%	Fair value hedge

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

		Interest Rate Swap Portfolio Fair Value at
Scenario	Resulting Classification	December 31, 2017				March 31, 2018				April 16, 2018
Fair value assuming no change in underlying interest rates	Asset (Liability)		$	(1.5	)		$	(1.6	)		$	(1.6	)
Fair value assuming 10% increase in underlying interest rates	Asset (Liability)			(1.8	)			(1.6	)			(1.6	)
Fair value assuming 10% decrease in underlying interest rates	Asset (Liability)			(1.2	)			(1.6	)			(1.6	)

The following table summarizes our portfolio of 30-year forward starting swaps outstanding at March 31, 2018.  Forward starting swaps hedge the expected underlying benchmark interest rates related to future issuances of debt.

Hedged Transaction	Number and Type of Derivatives Outstanding	Notional Amount		Expected Settlement Date	Average Rate Locked	Accounting Treatment
Future long-term debt offering	2 forward starting swaps	$	175.0	2/2019	2.56%	Cash flow hedge

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

		Forward Starting Swap Portfolio Fair Value at
Scenario	Resulting Classification	December 31, 2017				March 31, 2018				April 16, 2018
Fair value assuming no change in underlying interest rates	Asset (Liability)		$	(0.1	)		$	9.5			$	11.8
Fair value assuming 10% increase in underlying interest rates	Asset (Liability)			13.8				18.7				21.0
Fair value assuming 10% decrease in underlying interest rates	Asset (Liability)			(15.1	)			(0.3	)			1.9

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

We sold swaptions related to our interest rate hedging activities during the first quarter of 2018, which resulted in the recognition of $7.2 million of cash gains that are reflected as a reduction in interest expense for the quarter.   These swaptions expired in March 2018.  In April 2018, we sold additional swaptions related to our interest rate hedging activities for which we received $11.8 million in premiums.   The April 2018 swaptions expire in June 2018.

Item 5.    Other Information.

Disclosure Under Section 13(r) of the Securities Exchange Act of 1934

Under Section 13(r) of the Securities Exchange Act of 1934, as amended by the Iran Threat Reduction and Syria Human Rights Act of 2012, issuers are required to include certain disclosures in their periodic reports if they or any of their “affiliates” (as defined in Rule 12b-2 thereunder) have knowingly engaged in certain specified activities relating to Iran.  Disclosure is required even where the activities are conducted outside the U.S. by non-U.S. affiliates in compliance with applicable law, and even if the activities are not covered or prohibited by U.S. law.

In October 2014, we acquired approximately 65.9% of the limited partner interests of Oiltanking Partners, L.P. (“Oiltanking”), all of the member interests of OTLP GP, LLC (the general partner of Oiltanking or “Oiltanking GP”), and the incentive distribution rights held by Oiltanking GP from Oiltanking Holdings Americas, Inc. as the first step of a two-step acquisition of Oiltanking.  In February 2015, we completed the second step of this transaction consisting of the acquisition of the noncontrolling interests in Oiltanking.  Collectively, the first and second steps of the acquisition of Oiltanking and Oiltanking GP are referred to as the “Oiltanking acquisition.”

Marquard & Bahls AG (“M&B”), a German corporation and the former parent company of Oiltanking, is entitled to designate a nominee for election to the Board (the “M&B Designee”) as long as M&B and its affiliates beneficially own at least 27,403,676 of the common units we issued to M&B and its affiliates in connection with step one of the Oiltanking acquisition.  In the event that the M&B Designee becomes unable or unwilling to, or for another reason ceases to, serve as a member of the Board while M&B is entitled to maintain the M&B Designee, M&B may designate another person reasonably acceptable to the Board as a replacement. The initial M&B Designee, Dr. F. Christian Flach, resigned from the Board in November 2017.  No replacement for Dr. Flach has been nominated by M&B as of the filing date of this quarterly report.

M&B owns and controls Oiltanking GmbH, which in turn owns a joint venture interest in the Exir Chemical Terminal (“ECT”) in Iran via its wholly owned affiliates Oiltanking ME Holding GmbH (formerly named Oiltanking Iran GmbH) and OMEA GmbH.  This interest results from an investment dating back to 2002.  Oiltanking GmbH currently has the contractual right to vote for the appointment of two members of ECT’s three-member board.  Oiltanking GmbH provides no goods, services, technology, information or support to ECT and plays no role in the management or day-to-day operations of ECT.

ECT stores chemicals and hydrocarbons, including naphtha, linear alkyl benzene and n-hexane, for distribution in Iran and for export to Asia and Europe.  To our knowledge, ECT’s activities are in compliance with applicable U.S., European Union or United Nations sanctions laws.  ECT pays routine and standard charges (i) to the Petrochemical Special Economic Zone Organization (“Petzone”) for the use of pipelines and (ii) to the National Petrochemical Company (“NPC”), which operates the berth.  Petzone is a subsidiary of NPC, which is owned and controlled by the Government of Iran. As Oiltanking GmbH has no direct involvement in the day-to-day operations of ECT, we have no information regarding ECT’s intent to continue or not continue making the payments described above.

Oiltanking GmbH maintains an internal compliance program to ensure compliance with all applicable sanctions regimes, including sanctions laws maintained by the U.S., European Union and United Nations.  Although the existence of the routine payments described above may be reportable under Section 13(r), Oiltanking GmbH has informed us that neither it, nor any of its subsidiaries or affiliates, has engaged in any conduct that would be sanctionable under any of these legal regimes.

These computations take into account our consolidated operations and the distributed income from our equity method investees.  For purposes of these calculations, “earnings” is the amount resulting from adding and subtracting the following items:

Add the following, as applicable:

· consolidated pre-tax income from continuing operations before adjustment for income or loss from equity investees;

· fixed charges;

· amortization of capitalized interest;

· distributed income of equity investees; and

· our share of pre-tax losses of equity investees for which charges arising from guarantees are included in fixed charges.

From the subtotal of the added items, subtract the following, as applicable:

· interest capitalized;

· preference security dividend requirements of consolidated subsidiaries; and

· the noncontrolling interests in pre-tax income of subsidiaries that have not incurred fixed charges.

The term “fixed charges” means the sum of the following:  interest expensed and capitalized; amortized premiums, discounts and capitalized expenses related to indebtedness; an estimate of the interest within rental expense; and preference security dividend requirements of consolidated subsidiaries.

Summary of Significant Accounting Policies

Note 2.  Summary of Significant Accounting Policies

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

Adoption of New Revenue Recognition Policies on January 1, 2018

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

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

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

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

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

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

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

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

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

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

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

See Note 9 regarding our new revenue disclosures.

Impact of ASU 2016-18 on Restricted Cash Disclosures

We adopted Accounting Standard Update (“ASU”) No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash, in the fourth quarter of 2017 and applied this ASU retrospectively to the periods presented in our Unaudited Condensed Statements of Consolidated Cash Flows.  As a result, the decrease in restricted cash of $309.8 million was excluded from net cash used in investing activities for the three months ended March 31, 2017.

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

	March 31, 2018		December 31, 2017
Cash and cash equivalents	$	102.1	$	5.1
Restricted cash		113.5		65.2
Total cash, cash equivalents and restricted cash shown in the   Unaudited Condensed Statements of Consolidated Cash Flows	$	215.6	$	70.3

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, 2018 consisted of initial margin requirements of $28.2 million and variation margin requirements of $85.3 million. The initial margin requirements will be returned to us as the related derivative instruments are settled.  See Note 14 for information regarding our derivative instruments and hedging activities.

Future Adoption of New Lease Accounting Standard

In February 2016, the FASB issued ASC 842, Leases (“ASC 842”), which requires substantially all leases (with the exception of leases with a term of one year or less) to be recorded on the balance sheet using a method referred to as the right-of-use (“ROU”) asset approach. We will adopt the new standard on January 1, 2019 and apply it to (i) all new leases entered into after January 1, 2019 and (ii) all existing lease contracts as of January 1, 2019 through a cumulative adjustment to equity.  In accordance with this approach, our consolidated operating expenses for periods prior to January 1, 2019 will not be revised.

The new standard introduces two lease accounting models, which result in a lease being classified as either a “finance” or “operating” lease on the basis of whether the lessee effectively obtains control of the underlying asset during the lease term.  A lease would be classified as a finance lease if it meets one of five classification criteria, four of which are generally consistent with current lease accounting guidance.  By default, a lease that does not meet the criteria to be classified as a finance lease will be deemed an operating lease.  Regardless of classification, the initial measurement of both lease types will result in the balance sheet recognition of a 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.  Leases classified as a finance lease will be accounted for using the effective interest method.  Under this approach, a lessee will amortize the ROU asset (generally on a straight-line basis in a manner similar to depreciation) and the discount on the lease liability (as a component of interest expense).  Leases classified as an operating lease will result in the recognition of a single lease expense amount that is recorded on a straight-line basis (or another systematic basis, if more appropriate).

We are in the process of reviewing our lease agreements in light of the new guidance.  We anticipate that ASC 842 will result in changes to the way our operating leases are recorded, presented and disclosed in our consolidated financial statements.

Our minimum payment obligations under operating leases with terms in excess of one year totaled $431.9 million at March 31, 2018 (undiscounted). Upon adoption, we expect to recognize a ROU asset and a corresponding lease liability based on the present value of such obligations.  We currently do not have any capital lease obligations.

Inventories

Note 3.  Inventories

Our inventory amounts by product type were as follows at the dates indicated:

	March 31, 2018		December 31, 2017
NGLs	$	922.4	$	917.4
Petrochemicals and refined products		195.7		161.5
Crude oil		571.1		516.3
Natural gas		10.7		14.6
Total	$	1,699.9	$	1,609.8

Due to fluctuating commodity prices, we recognize lower of cost or market 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,
	2018		2017
Cost of sales (1)	$	7,140.4	$	5,335.7
Lower of cost or net realizable value adjustments within cost of sales		1.9		3.4
(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.

Less accumulated depreciation			11,261.3		10,924.8
Property, plant and equipment, net		$	36,416.3	$	35,620.4
(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.

On March 29, 2018, we acquired the remaining 50% member interest of our Delaware Processing joint venture, which resulted in the consolidation of approximately $200 million of property, plant and equipment.  See Note 11 for information regarding this recent acquisition.

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

	For the Three Months Ended March 31,
	2018		2017
Depreciation expense (1)	$	331.8	$	317.5
Capitalized interest (2)		58.2		39.6
(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, 2018 and December 31, 2017 includes $39.3 million and $39.9 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, 2018:

ARO liability balance, January 1, 2018	$	86.7

Parent-Subsidiary Guarantor Relationships

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

Issuance of $2.0 Billion of Senior Notes and $700 Million of Junior Subordinated Notes in February 2018

In February 2018, EPO issued $2.7 billion aggregate principal amount of notes comprised of (i) $750 million principal amount of senior notes due February 15, 2021 (“Senior Notes TT”), (ii) $1.25 billion principal amount of senior notes due February 15, 2048 (“Senior Notes UU”) and (iii) $700 million principal amount of junior subordinated notes due February 15, 2078 (“Junior Subordinated Notes F”).

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

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

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

Redemption of Junior Subordinated Notes B

On February 1, 2018, EPO notified its trustee and paying agent to redeem all of the $682.7 million outstanding aggregate principal amount of its Junior Subordinated Notes B.  The Junior Subordinated Notes B were redeemed on March 5, 2018 at a price equal to 100% of the principal amount of the notes being redeemed, plus all accrued and unpaid interest thereon to, but not including, the redemption date.

Lender Financial Covenants

We were in compliance with the financial covenants of our consolidated debt agreements at March 31, 2018.

Letters of Credit

At March 31, 2018, EPO had $66.4 million of letters of credit outstanding primarily related to our commodity hedging activities.

Note 8.  Equity and Distributions

Partners’ Equity

The following table summarizes changes in the number of our limited partner common units outstanding from January 1, 2018 to March 31, 2018:

Number of common units outstanding at January 1, 2018	2,161,089,479
Common units issued in connection with DRIP and EUPP	6,642,286
Common units issued in connection with the vesting of phantom unit awards	3,170,861
Cancellation of treasury units acquired in connection with the vesting of equity-based awards	(949,778	)
Common units issued in connection with employee compensation	1,443,586
Other	16,360
Number of common units outstanding at March 31, 2018	2,171,412,794

The net cash proceeds we received from the issuance of common units during the three months ended March 31, 2018 were used to temporarily reduce amounts outstanding under EPO’s commercial paper program and revolving credit facilities and for general company purposes.

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

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

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

During the three months ended March 31, 2018, we did not issue any common units under the ATM program.  During the three months ended March 31, 2017, we issued 12,865,371 common units under this program for aggregate gross cash proceeds of $359.7 million, resulting in total net cash proceeds of $356.0 million.

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

Distribution reinvestment plan.  We have a registration statement on file with the SEC in connection with our distribution reinvestment plan (“DRIP”).  The DRIP provides unitholders of record and beneficial owners of our common units a voluntary means by which they can increase the number of our common units they own by reinvesting the quarterly cash distributions they receive from us into the purchase of additional new common units.

We issued a total of 6,509,653 common units under our DRIP during the three months ended March 31, 2018, which generated net cash proceeds of $173.3 million.  Privately held affiliates of EPCO reinvested $100 million through the DRIP during the three months ended March 31, 2018 (this amount being a component of the net cash proceeds presented).  During the three months ended March 31, 2017, we issued 3,325,798 common units under our DRIP, which generated net cash proceeds of $89.6 million. 

After taking into account the number of common units issued under the DRIP through March 31, 2018, we have the capacity to issue an additional 74,207,487 common units under this plan.

Employee unit purchase plan.  In addition to the DRIP, we have registration statements on file with the SEC in connection with our employee unit purchase plan (“EUPP”).  We issued 132,633 common units under our EUPP during the three months ended March 31, 2018, which generated net cash proceeds of $3.7 million.  During the three months ended March 31, 2017, we issued 114,761 common units under our EUPP, which generated net cash proceeds of $3.2 million.  After taking into account the number of common units issued under the EUPP through March 31, 2018, we may issue an additional 5,628,178 common units under this plan.

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

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

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

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

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

The additional service revenue recognized for the non-cash consideration increased our total revenues by approximately 1% for the three months ended March 31, 2018 when compared to the amount of revenues we would have recognized under ASC 605 for the quarter.  Given the rapid turnover of our inventories of NGL products each month, we do not expect a significant change in our gross operating margin from natural gas processing and related NGL marketing activities as a result of the changes required by ASC 606.

Unbilled Revenue and Deferred Revenue

The following table provides information regarding our contract assets and contract liabilities as of March 31, 2018:

Contract Asset	Location	Balance
Unbilled revenue (current amount)	Prepaid and other current assets	$	64.4
Unbilled revenue (noncurrent)	Other assets		0.2
Total		$	64.6

Contract Liability	Location	Balance
Deferred revenue (current amount)	Other current liabilities	$	78.5
Deferred revenue (noncurrent)	Other long-term liabilities		140.6
Total		$	219.1

The following table presents significant changes in our unbilled revenue and deferred revenue balances during the three months ended March 31, 2018:

	Unbilled Revenue		Deferred Revenue
Balance at January 1, 2018 (upon adoption of ASC 606)	$	--	$	224.7
Amount included in opening balance transferred to other accounts during period (1)		--		(54.0	)
Amount recorded during period		62.4		86.0
Amounts recorded during period transferred to other accounts (1)		--		(37.6	)
Amount recorded in connection with business combination		2.2		--
Balance at March 31, 2018	$	64.6	$	219.1
(1)   Unbilled revenues are transferred to accounts receivable once we have an unconditional right to consideration from the customer. Deferred revenues are recognized as revenue upon satisfaction of our performance obligation to the customer.

Remaining Performance Obligations

The following table presents estimated fixed consideration from contracts with customers that contain minimum volume commitments, deficiency and similar fees and the term of the contracts exceeds one year. These amounts represent the revenues we expect to recognize in future periods from these contracts as of March 31, 2018.  For a significant portion of our revenue, we bill customers a contractual rate for the services provided multiplied by the amount of volume handled in a given period.  We have the right to invoice the customer in the amount that corresponds directly with the value of our performance completed to date.  Therefore, we are not required to disclose information about the variable consideration of remaining performance obligations as we recognize revenue equal to the amount that we have the right to invoice.

	Remainder of 2018		2019		2020		2021		2022		Thereafter		Total
Midstream services	$	1,704.7	$	2,155.1	$	1,945.8	$	1,484.3	$	1,110.0	$	4,179.6	$	12,579.5

Impact of Change in Accounting Policy – ASC 606 Transition Disclosures

The following information and tables are provided to summarize the material impacts of adopting ASC 606 on our consolidated financial statements for the three months ended March 31, 2018.

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

Unbilled revenues have historically been presented as a component of accounts receivable on our consolidated balance sheets.  Upon implementation of ASC 606, we reclassified these amounts to “Prepaid and other current assets” since these amounts represent conditional rights to consideration.  Once we have an unconditional right to consideration, the amount is transferred to accounts receivable.

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

Business Segments [Abstract]

Business Segments

Note 10.  Business Segments

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

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

Segment Gross Operating Margin

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

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

	For the Three Months Ended March 31,
	2018			2017
Operating income	$	1,138.5		$	1,031.6
Adjustments to reconcile operating income to total gross operating margin:
Add depreciation, amortization and accretion expense in operating costs and expenses		394.3			376.2
Add asset impairment and related charges in operating costs and expenses		0.9			11.2
Subtract net gains attributable to asset sales in operating costs and expenses		(0.5	)		(0.3	)
Add general and administrative costs		53.0			50.4
Adjustments for make-up rights on certain new pipeline projects:
Add non-refundable payments received from shippers attributable to make-up rights (1)		2.7			13.3
Subtract the subsequent recognition of revenues attributable to make-up rights (2)		(14.2	)		(9.1	)
Total segment gross operating margin	$	1,574.7		$	1,473.3
(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,
	2018		2017
Gross operating margin by segment:
NGL Pipelines & Services	$	884.9	$	856.0
Crude Oil Pipelines & Services		220.0		264.6
Natural Gas Pipelines & Services		197.9		170.9
Petrochemical & Refined Products Services		271.9		181.8

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

Other Revenue and Expense Information

The following table presents additional information regarding our consolidated revenues and costs and expenses for the periods indicated:

	For the Three Months Ended March 31,

General and administrative costs		53.0			50.4
Total consolidated costs and expenses	$	8,275.7		$	6,383.6
(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.

Business Combinations [Abstract]

Business Combinations

Note 11.   Business Combinations

On March 29, 2018, we acquired the remaining 50% member interest in our Delaware Processing joint venture for $153.6 million in cash.  As a result, Delaware Processing is now our wholly-owned consolidated subsidiary.  Delaware Processing owns a cryogenic natural gas processing facility having a capacity of 150 million cubic feet per day.  The facility is located in Reeves County, Texas and entered service in August 2016.  The acquired business serves growing production of NGL-rich natural gas from the Delaware Basin in West Texas and southern New Mexico.

The following table presents the preliminary fair value allocation of assets acquired and liabilities assumed in the acquisition at March 29, 2018. Due to the recent nature of this transaction, the allocation is provisional and subject to ongoing efforts to clarify the values assigned to tangible and identifiable intangible assets. We expect these open matters to be resolved by the end of the second quarter of 2018.

Cash paid for remaining 50% equity interest in Delaware Processing	$	153.6
Fair value of our 50% equity interest in Delaware Processing held before the acquisition		146.4
Total		300.0
Recognized amounts of identifiable assets acquired and liabilities assumed:
Assets acquired in business combination:
Current assets, including cash of $3.8 million	$	12.7
Property, plant and equipment		200.0
Contract-based intangible assets		78.8
Customer relationship intangible assets		10.4
Total assets acquired	$	301.9
Liabilities assumed in business combination:
Current liabilities	$	(1.3	)
Long-term liabilities		(0.6	)
Total liabilities assumed	$	(1.9	)
Total identifiable net assets	$	300.0
Goodwill	$	--

Prior to this acquisition, we accounted for our investment using the equity method.  On a historical pro forma basis, our revenues, costs and expenses, operating income, net income attributable to Enterprise Products Partners L.P. and earnings per unit amounts for the three months ended March 31, 2018 and 2017 would not have differed materially from those we actually reported had the acquisition been completed on January 1, 2017 rather than March 29, 2018.

At March 29, 2018, our 50% equity investment in Delaware Processing was $109.4 million.  Upon acquisition of the remaining 50% member interest, our existing equity investment was remeasured to fair value resulting in the recognition of a non-cash $37.0 million gain, which is presented within Other Income on our Unaudited Condensed Consolidated Statement of Operations for the three months ended March 31, 2018.

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

Equity-based Awards [Abstract]

Equity-based Awards

Note 13.  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,
	2018		2017
Equity-classified awards:
Phantom unit awards	$	24.6	$	22.8
Restricted common unit awards		--		0.5
Profits interest awards		1.6		1.5
Liability-classified awards		0.1		0.2
Total	$	26.3	$	25.0

The fair value of equity-classified awards is amortized into 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.

At March 31, 2018, all of the outstanding phantom unit awards were granted under the 2008 Plan.  The maximum number of common units authorized for issuance under the 2008 Plan was 45,000,000 at March 31, 2018.  This amount will automatically increase under the terms of the 2008 Plan by 5,000,000 common units on January 1, 2019 and will continue to automatically increase annually on each January 1 thereafter during the term of the 2008 Plan; provided, however, that in no event shall the maximum aggregate number exceed 70,000,000 common units.  After giving effect to awards granted under the 2008 Plan through March 31, 2018, a total of 18,717,222  additional common units were available for issuance under this plan.

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

Phantom Unit Awards

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

At March 31, 2018, substantially all of our phantom unit awards are expected to result in the issuance of common units upon vesting; therefore, the applicable awards are accounted for as equity-classified awards.  The grant date fair value of a phantom unit award is based on the market price per unit of our common units on the date of grant.  Compensation expense is recognized based on the grant date fair value, net of an allowance for estimated forfeitures, over the requisite service or vesting period.

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

	Number of Units			Weighted- Average Grant Date Fair Value per Unit (1)
Phantom unit awards at January 1, 2018		9,289,501		$	27.65
Granted (2)		4,940,081		$	26.81
Vested		(3,170,861	)	$	28.64
Forfeited		(74,656	)	$	26.98
Phantom unit awards at March 31, 2018		10,984,065		$	26.99
(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 2018 was $132.4 million based on a grant date market price of our common units ranging from $25.40 to $26.81 per unit. An estimated annual forfeiture rate of 3.2% was applied to these awards.

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

The following table presents supplemental information regarding phantom unit awards for the periods indicated:

	For the Three Months Ended March 31,
	2018		2017
Cash payments made in connection with DERs	$	3.9	$	3.2
Total intrinsic value of phantom unit awards that vested during period		82.0		63.2

For the EPCO group of companies, the unrecognized compensation cost associated with phantom unit awards was $187.5 million at March 31, 2018, of which our share of the cost is currently estimated to be $160.7 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

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

The following table summarizes key elements of each Employee Partnership as of March 31, 2018:

Employee Partnership	Enterprise Common Units contributed to Employee Partnership by EPCO Holdings	Class A Capital      Base (1)	Class A Preference Return (2)		Expected Vesting/ Liquidation Date	Estimated Grant Date Fair Value of Profits Interest   Awards (3)	Unrecognized Compensation   Cost (4)
PubCo I	2,723,052	$63.7 million	$	0.39	Feb. 2020	$13.2 million	$6.6 million
PubCo II	2,834,198	$66.3 million	$	0.39	Feb. 2021	$14.7 million	$8.6 million
PubCo III	105,000	$2.5 million	$	0.39	Apr. 2020	$0.5 million	$0.3 million
PrivCo I	1,111,438	$26.0 million	$	0.39	Feb. 2021	$5.8 million	$0.7 million
(1)   Represents fair market value of the Enterprise common units contributed to each Employee Partnership at the applicable contribution date. (2)   Each quarter, the Class A limited partner in each Employee Partnership is paid a cash distribution equal to the product of (i) the number of common units owned by the Employee Partnership and (ii) the Class A Preference Return of $0.39 per unit (subject to equitable adjustment in order to reflect any equity split, equity distribution or dividend, reverse split, combination, reclassification, recapitalization or other similar event affecting such common units). To the extent that the Employee Partnership has cash remaining after making this quarterly payment to the Class A limited partner, the residual cash is distributed to the Class B limited partners on a quarterly basis. (3)   Represents the total grant date fair value of the profits interest awards irrespective of how such costs will be allocated between us and EPCO and its privately held affiliates. (4)   Represents our expected share of the unrecognized compensation cost at March 31, 2018. We expect to recognize our share of the unrecognized compensation cost for PubCo I, PubCo II, PubCo III and PrivCo I over a weighted-average period of 1.9 years, 2.9 years, 2.0 years and 2.9 years, respectively.

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

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

	Expected	Risk-Free	Expected	Expected Unit
Employee	Life	Interest	Distribution	Price
Partnership	of Award	Rate	Yield	Volatility
PubCo I	4.0 years	0.9% to 2.2%	6.2% to 7.0%	24% to 40%
PubCo II	5.0 years	1.1% to 2.3%	6.1% to 7.0%	27% to 40%
PubCo III	4.0 years	1.0% to 2.2%	6.1% to 6.8%	27% to 40%
PrivCo I	5.0 years	1.2% to 1.6%	6.1% to 6.7%	28% to 40%

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

Derivative Instruments, Hedging Activities and Fair Value Measurements [Abstract]

Derivative Instruments, Hedging Activities and Fair Value Measurements

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

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

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

Interest Rate Hedging Activities

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

The following table summarizes our portfolio of interest rate swaps at March 31, 2018:

Hedged Transaction	Number and Type of Derivatives Outstanding	Notional Amount		Period of Hedge	Rate Swap	Accounting Treatment
Senior Notes OO	10 fixed-to-floating swaps	$	750.0	5/2015 to 5/2018	1.65% to 2.27%	Fair value hedge

The carrying amount of the Senior Notes OO was $749.4 million and $748.6 million at March 31, 2018 and December 31, 2017, respectively.  These carrying amounts, which are presented in “Current maturities of debt” on our Unaudited Condensed Consolidated Balance Sheets, are inclusive of cumulative fair value hedging adjustments of $0.6 million and $1.4 million at March 31, 2018 and December 31, 2017, respectively.

The following table summarizes our portfolio of forward starting swaps at March 31, 2018:

Hedged Transaction	Number and Type of Derivatives Outstanding	Notional Amount		Expected Settlement Date	Average Rate Locked	Accounting Treatment
Future long-term debt offering	2 forward starting swaps	$	175.0	2/2019	2.56%	Cash flow hedge

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

We sold swaptions related to our interest rate hedging activities during the first quarter of 2018, which resulted in the recognition of $7.2 million of cash gains that are reflected as a reduction in interest expense for the quarter. The swaptions expired in March 2018.

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

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

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

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

The following table summarizes our portfolio of commodity derivative instruments outstanding at March 31, 2018 (volume measures as noted):

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

Refined products risk management activities (MMBbls) (4)	2.3	n/a	Mark-to-market
Crude oil risk management activities (MMBbls) (4)	91.3	23.8	Mark-to-market
(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 2018 and December 2020, respectively. (3)   Current and long-term volumes include 42.4 Bcf and 3.0 Bcf, respectively, 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.

The carrying amount of our inventories subject to fair value hedges was $62.4 million and $84.0 million at March 31, 2018 and December 31, 2017, respectively.  These amounts, which are presented in “Inventories” on our Unaudited Condensed Consolidated Balance Sheets, are inclusive of cumulative fair value hedging adjustments of $3.0 million and $7.0 million at March 31, 2018 and December 31, 2017, respectively.

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

The following tables present the effect of our derivative instruments designated as fair value hedges on our Unaudited Condensed Statements of Consolidated Operations for the periods indicated:

Derivatives in Fair Value Hedging Relationships	Location	Gain (Loss) Recognized in Income on Derivative
		For the Three Months Ended March 31,
		2018			2017
Interest rate derivatives	Interest expense	$	0.7		$	(0.9	)
Commodity derivatives	Revenue		(0.2	)		18.8
Total		$	0.5		$	17.9

Derivatives in Fair Value Hedging Relationships	Location	Gain (Loss) Recognized in Income on Hedged Item
		For the Three Months Ended March 31,

Interest rate derivatives	Interest expense	$	(0.8	)	$	0.9
Commodity derivatives	Revenue		3.1			(12.4	)
Total		$	2.3		$	(11.5	)

The gain of $2.8 million and $6.4 million of net gain recognized during the three months ended March 31, 2018 and 2017, respectively, was primarily related to prompt-to-forward month price differentials that were excluded from the assessment of hedge effectiveness.

The following tables present the effect of our derivative instruments designated as cash flow hedges on our Unaudited Condensed Statements of Consolidated Operations and Unaudited Condensed Statements of Consolidated Comprehensive Income for the periods indicated:

Derivatives in Cash Flow Hedging Relationships	Change in Value Recognized in Other Comprehensive Income (Loss) on Derivative
	For the Three Months Ended March 31,
	2018		2017
Interest rate derivatives	$	11.1	$	2.4
Commodity derivatives – Revenue (1)		3.0		147.6
Commodity derivatives – Operating costs and expenses (1)		0.4		(2.8	)
Total	$	14.5	$	147.2
(1)   The fair value of these derivative instruments will be reclassified to their respective locations on the Unaudited Condensed Statement of Consolidated Operations upon settlement of the underlying derivative transactions, as appropriate.

Derivatives in Cash Flow Hedging Relationships	Location	Gain (Loss) Reclassified from Accumulated Other Comprehensive Income (Loss) to Income
		For the Three Months Ended March 31,
		2018			2017
Interest rate derivatives	Interest expense	$	(10.5	)	$	(9.6	)
Commodity derivatives	Revenue		14.0			(7.5	)
Commodity derivatives	Operating costs and expenses		0.5			0.4
Total		$	4.0		$	(16.7	)

Over the next twelve months, we expect to reclassify $37.2 million of losses attributable to interest rate derivative instruments from accumulated other comprehensive loss to earnings as an increase in interest expense.  Likewise, we expect to reclassify $21.3 million of net losses attributable to commodity derivative instruments from accumulated other comprehensive loss to earnings, $20.8 million as a decrease in revenue and $0.5 million as an increase in operating costs and expenses.

The following table presents the effect of our derivative instruments not designated as hedging instruments on our Unaudited Condensed Statements of Consolidated Operations for the periods indicated:

Derivatives Not Designated as Hedging Instruments	Location	Gain (Loss) Recognized in Income on Derivative
		For the Three Months Ended March 31,
		2018			2017
Commodity derivatives	Revenue	$	(153.5	)	$	15.7
Commodity derivatives	Operating costs and expenses		(1.5	)		4.5
Total		$	(155.0	)	$	20.2

The $155.0 million loss recognized in first quarter of 2018 earnings from derivatives not designated as hedging instruments reflects $21.7 million of realized losses on such instruments.  It does not reflect the $7.2 million of unrealized losses from fair value hedges.  In the aggregate, our unrealized mark-to-market losses for the first quarter of 2018 were $140.5 million inclusive of all derivative instrument types.   The following table summarizes the impact of net unrealized, mark-to-market losses on our gross operating margin by segment for the three months ended March 31, 2018:

Unrealized mark-to-market gains (losses) by segment:
NGL Pipelines & Services	$	(3.5	)
Crude Oil Pipelines & Services		(129.6	)
Natural Gas Pipelines & Services		(5.8	)
Petrochemical & Refined Products Services		(1.6	)
Total	$	(140.5	)

Fair Value Measurements

The following tables set forth, by level within the Level 1, 2 and 3 fair value hierarchy, the carrying values of our financial assets and liabilities at the dates indicated.  These assets and liabilities are measured on a recurring basis and are classified based on the lowest level of input used to estimate their fair value.  Our assessment of the relative significance of such inputs requires judgment.

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

Total financial liabilities	$	--		$	176.9		$	335.6	$	512.5

Our Level 3 financial liabilities at March 31, 2018 and December 31, 2017 primarily reflect the fair value assigned to the Liquidity Option Agreement (see Note 16) at each measurement date.  The carrying value of the Liquidity Option Agreement (a long-term liability) was $341.4 million and $333.9 million at March 31, 2018 and December 31, 2017, respectively.

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	2018			2017
Financial liability balance, net, January 1		$	(332.7	)	$	(268.2	)
Total gains (losses) included in:
Net income (1)	Revenue		(0.5	)		0.7

Transfers out of Level 3			--			--
Financial liability balance, net, March 31		$	(341.9	)	$	(274.4	)
(1)   There were unrealized losses of $1.7 million and unrealized losses of $0.7 million included in these amounts for the three months ended March 31, 2018 and 2017, respectively.

The followingtable provides quantitative information regarding our recurring Level 3 fair value measurements for commodity derivatives at March 31, 2018:

	Fair Value
	Financial Assets		Financial Liabilities		Valuation Techniques	Unobservable Input	Range
Commodity derivatives – Crude oil	$	0.4	$	0.9	Discounted cash flow	Forward commodity prices	$63.78-$65.07/barrel
Total	$	0.4	$	0.9

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, 2018.  In general, changes in the price of the underlying commodity increases or decreases the fair value of a commodity derivative depending on whether the derivative was purchased or sold.  We generally expect changes in the fair value of our derivative instruments to be offset by corresponding changes in the fair value of our hedged exposures.

Nonrecurring Fair Value Measurements

The following table summarizes our non-cash asset impairment charges for long-lived assets by segment during each of the periods indicated:

	For the Three Months Ended March 31,
	2018		2017
NGL Pipelines & Services	$	--	$	0.2
Crude Oil Pipelines & Services		0.2		--
Natural Gas Pipelines & Services		0.7		0.2
Petrochemical & Refined Products Services		--		--
Total	$	0.9	$	0.4

Impairment charges are primarily 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 $24.73  billion and $23.47 billion at March 31, 2018 and December 31, 2017, respectively.  The aggregate carrying value of these debt obligations was $23.50 billion and $21.48 billion at March 31, 2018 and December 31, 2017, respectively.  These values are based on quoted market prices for such debt or debt of similar terms and maturities (Level 2), our credit standing and the credit standing of our counterparties.  Changes in market rates of interest affect the fair value of our fixed-rate debt.  The amounts reported for fixed-rate debt obligations exclude those amounts hedged using fixed-to-floating interest rate swaps. See “Interest Rate Hedging Activities” within this Note 14 for additional information.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.

Of the total number of units held by EPCO and its privately held affiliates, 81,346,154 have been pledged as security under the credit facilities of EPCO and its privately held affiliates at March 31, 2018.  These credit facilities contain customary and other events of default, including defaults by us and other affiliates of EPCO.  An event of default, followed by a foreclosure on the pledged collateral, could ultimately result in a change in ownership of these units and affect the market price of our common units.

We and Enterprise GP are both separate legal entities apart from each other and apart from EPCO and its other affiliates, with assets and liabilities that are also separate from those of EPCO and its other affiliates.  EPCO and its privately held affiliates depend on the cash distributions they receive from us and other investments to fund their other activities and to meet their debt obligations.  During the three months ended March 31, 2018 and 2017, we paid EPCO and its privately held affiliates cash distributions totaling $286.9  million and $275.2 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, 2018, privately held affiliates of EPCO reinvested $100 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:

Commitments and Contingencies [Abstract]

Commitments and Contingencies

Note 16.  Commitments and Contingencies

Litigation

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

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

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

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

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

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

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

On 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.  As of March 31, 2018, we have not recorded a provision for this matter as management continues to believe that payment of damages by us in this case is not probable. We continue to monitor developments involving this matter.

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

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

Contractual Obligations

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

Operating Lease Obligations.  Consolidated lease and rental expense was $25.6 million and $26.2 million during the three months ended March 31, 2018 and 2017, respectively.  Our operating lease commitments at March 31, 2018 did not differ materially from those reported in our 2017 Form 10-K.

Purchase Obligations.  Our consolidated purchase obligations at March 31, 2018 did not differ materially from those reported in our 2017 Form 10-K. 

Liquidity Option Agreement

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

The carrying value of the Liquidity Option Agreement, which is a component of “Other long-term liabilities” on our Unaudited Condensed Consolidated Balance Sheet, was $341.4 million and $333.9 million at March 31, 2018 and December 31, 2017, respectively.  The fair value of the Liquidity Option, at any measurement date, represents the present value of estimated federal and state income tax payments that we believe a market participant would incur on the future taxable income of OTA. We expect that OTA’s taxable income would, in turn, be based on an allocation of our partnership’s taxable income to the common units then held by OTA and reflect any tax planning we believe could be employed. Our valuation estimate for the Liquidity Option at March 31, 2018 is based on several inputs that are not observable in the market (i.e., Level 3 inputs) such as the following:

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

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

 OTA’s ownership interest in Enterprise common units is assumed to be diluted over time in connection with Enterprise’s issuance of equity for general company reasons.  For purposes of the valuation at March 31, 2018, we used ownership interests ranging from 1.8% to 2.5%;

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

 A discount rate of 7.6% based on our weighted-average cost of capital at March 31, 2018.

Furthermore, our valuation estimate incorporates probability-weighted scenarios reflecting the likelihood that M&B may elect to divest a portion of the Enterprise common units held by OTA prior to exercise of the option.  At March 31, 2018, based on these scenarios, we expect that OTA would own approximately 90.5% 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 had 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, 2018 would have increased by $35.6 million.

Changes in the fair value of the Liquidity Option are recognized in earnings as a component of other income (expense) on our Unaudited Condensed Statements of Consolidated Operations.  Results for the three months ended March 31, 2018 and 2017 include $7.5 million and $5.5 million, respectively, of aggregate non-cash expense attributable to accretion and changes in management estimates regarding inputs to the valuation model.

Summary of Significant Accounting Policies [Abstract]

Recent Accounting Developments

Adoption of New Revenue Recognition Policies on January 1, 2018

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

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

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

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

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

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

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

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

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

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

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

See Note 9 regarding our new revenue disclosures.

Impact of ASU 2016-18 on Restricted Cash Disclosures

We adopted Accounting Standard Update (“ASU”) No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash, in the fourth quarter of 2017 and applied this ASU retrospectively to the periods presented in our Unaudited Condensed Statements of Consolidated Cash Flows.  As a result, the decrease in restricted cash of $309.8 million was excluded from net cash used in investing activities for the three months ended March 31, 2017.

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

	March 31, 2018		December 31, 2017
Cash and cash equivalents	$	102.1	$	5.1
Restricted cash		113.5		65.2
Total cash, cash equivalents and restricted cash shown in the   Unaudited Condensed Statements of Consolidated Cash Flows	$	215.6	$	70.3

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, 2018 consisted of initial margin requirements of $28.2 million and variation margin requirements of $85.3 million. The initial margin requirements will be returned to us as the related derivative instruments are settled.  See Note 14 for information regarding our derivative instruments and hedging activities.

Future Adoption of New Lease Accounting Standard

In February 2016, the FASB issued ASC 842, Leases (“ASC 842”), which requires substantially all leases (with the exception of leases with a term of one year or less) to be recorded on the balance sheet using a method referred to as the right-of-use (“ROU”) asset approach. We will adopt the new standard on January 1, 2019 and apply it to (i) all new leases entered into after January 1, 2019 and (ii) all existing lease contracts as of January 1, 2019 through a cumulative adjustment to equity.  In accordance with this approach, our consolidated operating expenses for periods prior to January 1, 2019 will not be revised.

The new standard introduces two lease accounting models, which result in a lease being classified as either a “finance” or “operating” lease on the basis of whether the lessee effectively obtains control of the underlying asset during the lease term.  A lease would be classified as a finance lease if it meets one of five classification criteria, four of which are generally consistent with current lease accounting guidance.  By default, a lease that does not meet the criteria to be classified as a finance lease will be deemed an operating lease.  Regardless of classification, the initial measurement of both lease types will result in the balance sheet recognition of a 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.  Leases classified as a finance lease will be accounted for using the effective interest method.  Under this approach, a lessee will amortize the ROU asset (generally on a straight-line basis in a manner similar to depreciation) and the discount on the lease liability (as a component of interest expense).  Leases classified as an operating lease will result in the recognition of a single lease expense amount that is recorded on a straight-line basis (or another systematic basis, if more appropriate).

We are in the process of reviewing our lease agreements in light of the new guidance.  We anticipate that ASC 842 will result in changes to the way our operating leases are recorded, presented and disclosed in our consolidated financial statements.

Our minimum payment obligations under operating leases with terms in excess of one year totaled $431.9 million at March 31, 2018 (undiscounted). Upon adoption, we expect to recognize a ROU asset and a corresponding lease liability based on the present value of such obligations.  We currently do not have any capital lease obligations.

(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.

Depreciation Expense and Capitalized Interest

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

	For the Three Months Ended March 31,
	2018		2017
Depreciation expense (1)	$	331.8	$	317.5
Capitalized interest (2)		58.2		39.6
(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.

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

Unbilled Revenue and Deferred Revenue

The following table provides information regarding our contract assets and contract liabilities as of March 31, 2018:

Contract Asset	Location	Balance
Unbilled revenue (current amount)	Prepaid and other current assets	$	64.4
Unbilled revenue (noncurrent)	Other assets		0.2

Contract Liability	Location	Balance
Deferred revenue (current amount)	Other current liabilities	$	78.5
Deferred revenue (noncurrent)	Other long-term liabilities		140.6
Total		$	219.1

The following table presents significant changes in our unbilled revenue and deferred revenue balances during the three months ended March 31, 2018:

	Unbilled Revenue		Deferred Revenue
Balance at January 1, 2018 (upon adoption of ASC 606)	$	--	$	224.7
Amount included in opening balance transferred to other accounts during period (1)		--		(54.0	)

Amount recorded in connection with business combination		2.2		--
Balance at March 31, 2018	$	64.6	$	219.1
(1)   Unbilled revenues are transferred to accounts receivable once we have an unconditional right to consideration from the customer. Deferred revenues are recognized as revenue upon satisfaction of our performance obligation to the customer.

Remaining Performance Obligations

The following table presents estimated fixed consideration from contracts with customers that contain minimum volume commitments, deficiency and similar fees and the term of the contracts exceeds one year. These amounts represent the revenues we expect to recognize in future periods from these contracts as of March 31, 2018.  For a significant portion of our revenue, we bill customers a contractual rate for the services provided multiplied by the amount of volume handled in a given period.  We have the right to invoice the customer in the amount that corresponds directly with the value of our performance completed to date.  Therefore, we are not required to disclose information about the variable consideration of remaining performance obligations as we recognize revenue equal to the amount that we have the right to invoice.

Business Segments [Abstract]

Measurement of Total Segment Gross Operating Margin

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

	For the Three Months Ended March 31,
	2018			2017
Operating income	$	1,138.5		$	1,031.6
Adjustments to reconcile operating income to total gross operating margin:
Add depreciation, amortization and accretion expense in operating costs and expenses		394.3			376.2
Add asset impairment and related charges in operating costs and expenses		0.9			11.2
Subtract net gains attributable to asset sales in operating costs and expenses		(0.5	)		(0.3	)
Add general and administrative costs		53.0			50.4
Adjustments for make-up rights on certain new pipeline projects:
Add non-refundable payments received from shippers attributable to make-up rights (1)		2.7			13.3
Subtract the subsequent recognition of revenues attributable to make-up rights (2)		(14.2	)		(9.1	)
Total segment gross operating margin	$	1,574.7		$	1,473.3
(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)   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 2018 was $132.4 million based on a grant date market price of our common units ranging from $25.40 to $26.81 per unit. An estimated annual forfeiture rate of 3.2% was applied to these awards.

The following table summarizes key elements of each Employee Partnership as of March 31, 2018:

Employee Partnership	Enterprise Common Units contributed to Employee Partnership by EPCO Holdings	Class A Capital      Base (1)	Class A Preference Return (2)		Expected Vesting/ Liquidation Date	Estimated Grant Date Fair Value of Profits Interest   Awards (3)	Unrecognized Compensation   Cost (4)

PrivCo I	1,111,438	$26.0 million	$	0.39	Feb. 2021	$5.8 million	$0.7 million
(1)   Represents fair market value of the Enterprise common units contributed to each Employee Partnership at the applicable contribution date. (2)   Each quarter, the Class A limited partner in each Employee Partnership is paid a cash distribution equal to the product of (i) the number of common units owned by the Employee Partnership and (ii) the Class A Preference Return of $0.39 per unit (subject to equitable adjustment in order to reflect any equity split, equity distribution or dividend, reverse split, combination, reclassification, recapitalization or other similar event affecting such common units). To the extent that the Employee Partnership has cash remaining after making this quarterly payment to the Class A limited partner, the residual cash is distributed to the Class B limited partners on a quarterly basis. (3)   Represents the total grant date fair value of the profits interest awards irrespective of how such costs will be allocated between us and EPCO and its privately held affiliates. (4)   Represents our expected share of the unrecognized compensation cost at March 31, 2018. We expect to recognize our share of the unrecognized compensation cost for PubCo I, PubCo II, PubCo III and PrivCo I over a weighted-average period of 1.9 years, 2.9 years, 2.0 years and 2.9 years, respectively.

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

Fair Value Measurements of Financial Assets and Liabilities Measured on a Recurring Basis

The following tables set forth, by level within the Level 1, 2 and 3 fair value hierarchy, the carrying values of our financial assets and liabilities at the dates indicated.  These assets and liabilities are measured on a recurring basis and are classified based on the lowest level of input used to estimate their fair value.  Our assessment of the relative significance of such inputs requires judgment.

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

[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.

[3] 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.

[4] 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.

[5] Underground and other storage facilities include underground product storage caverns; above ground storage tanks; water wells and related assets.

[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.

[7] Transportation equipment includes tractor-trailer tank trucks and other vehicles and similar assets used in our operations.

[8] Marine vessels include tow boats, barges and related equipment used in our marine transportation business.

[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.

[1] Represents fair market value of the Enterprise common units contributed to each Employee Partnership at the applicable contribution date.

[2] Each quarter, the Class A limited partner in each Employee Partnership is paid a cash distribution equal to the product of (i) the number of common units owned by the Employee Partnership and (ii) the Class A Preference Return of $0.39 per unit (subject to equitable adjustment in order to reflect any equity split, equity distribution or dividend, reverse split, combination, reclassification, recapitalization or other similar event affecting such common units). To the extent that the Employee Partnership has cash remaining after making this quarterly payment to the Class A limited partner, the residual cash is distributed to the Class B limited partners on a quarterly basis.

[3] Represents the total grant date fair value of the profits interest awards irrespective of how such costs will be allocated between us and EPCO and its privately held affiliates.

[4] Represents our expected share of the unrecognized compensation cost at March 31, 2018. We expect to recognize our share of the unrecognized compensation cost for PubCo I, PubCo II, PubCo III and PrivCo I over a weighted-average period of 1.9 years, 2.9 years, 2.0 years and 2.9 years, respectively.
