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 20172018 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
Cash, Cash Equivalents 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.Restricted Cash

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

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

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

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

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

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

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

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

Under certain midstream service agreements, customers are required to provide a minimum volume over an agreed-upon period with a provision that allows the customer to make-up any volume shortfalls over an agreed-upon period (referred to as 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 $319.1 million was excluded from net cash used in investing activities for the six months ended June 30, 2017.

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 June 30, 2018March 31, 2019 consisted of initial margin requirements of $51.4$34.3 million andpartially offset by positive variation margin requirements of $232.2$26.1 million. The initial margin requirements will be returned to us as the related derivative instruments are settled.  See Note 1413 for information regarding our derivative instruments and hedging activities.

Recent Accounting Developments

Future Adoption of New Lease Accounting Standardaccounting standard
In February 2016, the FASBFinancial Accounting Standards Board (“FASB”) issued ASCAccounting Standards Codification (“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.sheet. We will adoptadopted the new standard on January 1, 2019 and applyapplied 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.2019. ASC 842 supersedes existing lease accounting guidance found under ASC 840, Leases.

The new standard introduces two leaselessee accounting models, which result in a lease being classified as either a “finance” or “operating” lease based 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 currentASC 840 lease accounting guidance.  By default, a lease that does not meet the criteria to be classified as a finance lease will be deemed an operating lease.  Regardless of classification, the initial measurement of both lease types will result in the balance sheet recognition of a ROUright-of-use (“ROU”) asset representing(representing a company’s right to use the underlying asset for a specified period of timetime) 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 aFor finance lease will be accounted for using the effective interest method.  Under this approach,leases, a lessee will amortize the ROU asset (generally on a straight-line basis in a manner similar to depreciation) and the discount onaccrete the lease liability (as a component of interest expense) using the effective interest methodLeases classified as an operating leaseOperating leases 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).basis.

We are in the process of reviewing our lease agreements in light of the new guidance.  We anticipate that ASC 842 will resultresulted 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 $430.0 million at June 30, 2018 (undiscounted). Upon adoption of ASC 842 on January 1, 2019, we expect to recognizerecognized a ROU asset and a corresponding lease liability based on the present value of suchthen existing long-term operating lease obligations. Based on current estimates,In addition, we expect that the totalelected to apply several practical expedients and made accounting policy elections upon adoption of ROU assets we would recognize under ASC 842 will account for less than 1% of total consolidated assets. Likewise, the correspondingincluding:

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

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

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

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

We issued $1.4 billion of short-term notes under EPO’s commercial paper program, partially offset by the repayment of $700 million principal amount of Senior Notes N during the first quarter of 2019.

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.

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

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
In March 2018, EPO redeemed all of the $682.7 million outstanding aggregate principal amount of its Junior Subordinated Notes B at a price equal to 100% of the principal amount of the notes being redeemed, plus all accrued and unpaid interest thereon to, but not including, the redemption date.

Distribution reinvestment planCommon unit repurchases under 2019 Buyback Program
In January 2019, we announced that the Board of Enterprise GP had approved a $2.0 billion multi-year unit buyback program (the “2019 Buyback Program”), which provides the partnership with an additional method to return capital to investors. The 2019 Buyback Program authorizes the partnership to repurchase its common units from time to time, including through open market purchases and negotiated transactions.  The timing and pace of buy backs under the program will be determined by a number of factors including (i) our financial performance and flexibility, (ii) organic growth and acquisition opportunities with higher potential returns on investment, (iii) our unit price and implied cash flow yield and (iv) maintaining targeted financial leverage with a debt-to-normalized adjusted EBITDA, or earnings before interest, taxes, depreciation and amortization, ratio in the 3.5 times area.  No time limit has been set for completion of the program, and it may be suspended or discontinued at any time.

We repurchased 1,852,392 common units under the 2019 Buyback Program during the three months ended March 31, 2019 for a total purchase price of $51.6 million, excluding commissions and fees. The repurchased units were cancelled immediately upon acquisition.  At March 31, 2019, the remaining available capacity under the 2019 Buyback Program was $1.95 billion.

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.

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

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

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

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

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 and Related Information

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 June 30,
  
For the Six Months
Ended June 30,
 
  2018  2017  2018  2017 
Operating income $986.4  $938.7  $2,124.9  $1,970.3 
Adjustments to reconcile operating income to total gross operating margin:                
   Add depreciation, amortization and accretion expense in operating costs and expenses  425.3   379.2   819.6   755.4 
   Add asset impairment and related charges in operating costs and expenses  15.9   14.0   16.8   25.2 
   Add net losses or subtract net gains attributable to asset sales in operating costs and expenses  (0.9)  0.3   (1.4)  -- 
   Add general and administrative costs  51.4   45.7   104.4   96.1 
Adjustments for make-up rights on certain new pipeline projects:                
   Add non-refundable payments received from shippers attributable to make-up rights (1)  5.6   8.3   8.3   21.6 
   Subtract the subsequent recognition of revenues attributable to make-up rights (2)  (22.0)  (6.8)  (36.2)  (15.9)
Total segment gross operating margin $1,461.7  $1,379.4  $3,036.4  $2,852.7 
                 
(1)   Since make-up rights entail a future performance obligation by the pipeline to the shipper, these receipts are recorded as deferred revenue for GAAP purposes; however, these receipts are included in gross operating margin in the period of receipt since they are nonrefundable to the shipper.
(2)   As deferred revenues attributable to make-up rights are subsequently recognized as revenue under GAAP, gross operating margin must be adjusted to remove such amounts to prevent duplication since the associated non-refundable payments were previously included in gross operating margin.
 
  
For the Three Months
Ended March 31,
 
  2019  2018 
Operating income $1,626.2  $1,138.5 
Adjustments to reconcile operating income to total segment gross operating margin

  2.2   2.7 
     Subsequent recognition of revenues attributable to make-up rights (2)  (7.5)  (14.2)
Total segment gross operating margin $2,128.4  $1,574.7 
         
(1) Since make-up rights entail a future performance obligation by the pipeline to the shipper, these receipts are recorded as deferred revenue for GAAP purposes; however, these receipts are included in gross operating margin in the period of receipt since they are nonrefundable to the shipper.
(2) As deferred revenues attributable to make-up rights are subsequently recognized as revenue under GAAP, gross operating margin must be adjusted to remove such amounts to prevent duplication since the associated non-refundable payments were previously included in gross operating margin.
 

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

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


Note 11.   Business Combinations

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

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

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

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

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

At June 30, 2018, all of the outstanding phantom unit awards were granted under the 2008 Plan.  The maximum number of common units authorized for issuance under the 2008 Plan was 45,000,000 at June 30, 2018.  This amount will automatically increase under the terms of the 2008 Plan by 5,000,000 common units on January 1, 2019 and will continue to automatically increase annually on each January 1 thereafter during the term of the 2008 Plan; provided, however, that in no event shall the maximum aggregate number exceed 70,000,000 common units.  After giving effect to awards granted under the 2008 Plan through June 30, 2018, a total of 18,864,940 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 June 30, 2018, substantially all of our phantom unit awards are expected to result in the issuance of common units upon vesting; therefore, the applicable awards are accounted for as equity-classified awards.  The grant date fair value of a phantom unit award is based on the market price per unit of our common units on the date of grant.  Compensation expense is recognized based on the grant date fair value, net of an allowance for estimated forfeitures, over the requisite service or vesting period.

Note 14.13.  Derivative Instruments, Hedging Activities and Fair Value Measurements

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

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 forward starting swaps at June 30, 2018:

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

In January 2018, weWe sold swaptions related to our interest rate hedging activities that resulted in the recognition of $7.2$9.8 million of cash gains that were reflected as a reduction in interest expense for the first quarter of 2018.  Likewise, in April 2018, we sold swaptions related to our interest rate hedging activities that resulted in the recognition2019.

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 June 30, 2018,March 31, 2019, our predominant commodity hedging strategies consisted of (i) hedging anticipated future purchases and sales of commodity products associated with transportation, storage and blending activities, (ii) hedging natural gas processing margins and (iii) hedging the fair value of commodity products held in inventory.

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.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

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

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

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

With respect to commodity derivatives, we believe forward commodity prices are the most significant unobservable inputs in determining our Level 3 recurring fair value measurements at June 30, 2018.March 31, 2019.  In general, changes in the price of the underlying commodity increases or decreases the fair value of a commodity derivative depending on whether the derivative was purchased or sold.  We generally expect changes in the fair value of our derivative instruments to be offset by corresponding changes in the fair value of our hedged exposures.

Of the total number of units held by EPCO and its privately held affiliates, 108,222,618 have been pledged as security under the credit facilities of EPCO and its privately held affiliates at June 30, 2018.March 31, 2019.  These credit facilities contain customary and other events of default, including defaults by us and other affiliates of EPCO.  An event of default, followed by a foreclosure on the pledged collateral, could ultimately result in a change in ownership of these units and affect the market price of our common units.

We and Enterprise GP are both separate legal entities apart from each other and apart from EPCO and its other affiliates, with assets and liabilities that are also separate from those of EPCO and its other affiliates.  EPCO and its privately held affiliates depend on the cash distributions they receive from us and other investments to fund their other activities and to meet their debt obligations.  During the sixthree months ended June 30,March 31, 2019 and 2018, and 2017, we paid EPCO and its privately held affiliates cash distributions totaling $576.3$296.0 million and $553.7$286.9 million, respectively.

From time-to-time, EPCO and its privately held affiliates elect to purchase additional common units under our DRIP and ATM program.  During the sixthree months ended June 30, 2018,March 31, 2019, privately held affiliates of EPCO reinvested $100$7 million through the DRIP.  See Note 8 for additional information regarding our DRIP.

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

Note 16.15.  Commitments and Contingencies

Litigation

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

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.
39

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

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 June 30, 2018March 31, 2019 and December 31, 2017,2018, our accruals for litigation contingencies were $4.5$0.5 million and $0.5 million, respectively, and recorded in our Unaudited Condensed Consolidated Balance Sheets as a component of “Other current liabilities.”  Our evaluation of litigation contingencies is based on the facts and circumstances of each case and predicting the outcome of these matters involves uncertainties.  In the event the assumptions we use to evaluate these matters change in future periods or new information becomes available, we may be required to record additional accruals.  In an effort to mitigate expenses associated with litigation, we may settle legal proceedings out of court.

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

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

We filed our Brief of the Appellant in the Court of Appeals for the Fifth District of Dallas, Texas on March 30, 2015 and ETP filed its Brief of Appellees on June 29, 2015.  We filed our Reply Brief of Appellant on September 18, 2015.  Oral argument was conducted on April 20, 2016, and the case was then submitted to the Court of Appeals for its consideration.  On July 18,July18, 2017, a panel of the Dallas Court of Appeals issued a unanimous opinion reversing the trial court’s judgment as to all of ETP’s claims against us, rendering judgment that ETP take nothing on those claims, and affirming our counterclaim against ETP of 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.   On June 8, 2018, the Supreme Court of Texas requested that the parties file briefs on the merits, and the parties are draftinghave filed their respective submittals.As of June 30, 2018, we

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

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

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

In total, operating lease expense was $27.0 million and 2017, respectively.  For$25.6 million for the sixthree months ended June 30,March 31, 2019 and 2018, respectively.  Operating lease expense represents less than 1% of “Operating costs and 2017,expenses” as presented on our consolidated statements of operations.  Fixed lease expense is charged to earnings on a straight-line basis over the contractual term, with any variable lease payments expensed as incurred.  Short-term lease expense is expensed as incurred.

We recognized $246.1 million in ROU assets and rental expenselease liabilities for long-term operating leases at January 1, 2019 in connection with the adoption of ASC 842.  These amounts represented less than 1% of our total consolidated assets and liabilities, respectively, at the adoption date. On an undiscounted basis, our long-term operating lease obligations aggregated to $314.4 million at January 1, 2019.

Under ASC 842, lessors classify leases as either operating, direct financing or sales-type.  We do not have any significant operating or direct financing leases.  Our operating lease income for the three months ended March 31, 2019 was $51.4$4.8 million, and $52.1 million, respectively.  which represented less than 1% of our consolidated revenues.  We do not have any sales-type leases.

Liquidity Option Agreement

We entered into a put option agreement (the “Liquidity Option Agreement” or “Liquidity Option”) with Oiltanking Holding Americas, Inc. (“OTA”) and Marquard & Bahls AG (“M&B”), a German corporation and the ultimate parent company of OTA, (“M&B”), in connection with the first step of the Oiltanking acquisition in 2014 (“Step 1”).  Under the Liquidity Option Agreement, we granted M&B the option to sell to us 100% of the issued and outstanding capital stock of OTA at any time within a 90-day period commencing on February 1, 2020.  If the Liquidity Option is exercised during this period, we would indirectly acquire anythe Enterprise common units then owned by OTA, currently 54,807,352 units,  and assume all future income tax obligations of OTA associated with (i) owning partnershipcommon units encumbered by the entity-level taxes of a U.S. corporation and (ii) OTA’sany associated net deferred tax liabilities.  To the extent that the sum of OTA’staxes.  If we assume net deferred tax liabilities exceedsthat exceed the then current book value of the Liquidity Option liability at the exercise date, we wouldwill 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 $350.3$447.8 million and $333.9$390.0 million at June 30, 2018March 31, 2019 and December 31, 2017,2018, respectively.  The fair value of the Liquidity Option, at any measurement date, represents the present value of estimated federal and state income tax payments that we believe a market participant would incur on the future taxable income of OTA. We expect that OTA’s taxable income would, in turn, be based on an allocation of our partnership’s taxable income to the common units then held by OTA and reflect anycertain tax planning strategies we believe could be employed.

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 June 30, 2018, we used ownership interests ranging from 1.8% to 2.5%;

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

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 50,00049,200 miles of pipelines; 260 MMBbls of storage capacity for NGLs, crude oil, petrochemicals and refined products; and 14 Bcf of natural gas storage capacity.    

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

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

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


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

Significant Recent Developments

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

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

In July 2018, we completed a second partial loadingApril 2019, our Midland-to-ECHO 2 Pipeline System, which provides us with approximately 200 MBPD of a VLCC tanker atincremental crude oil transportation capacity from the Seaway terminal. The Eagle Victoria loaded approximately 1.1 MMBbls at the terminal, with the balance completed using lightering vesselsPermian Basin to markets in the Gulf of Mexico.

Affiliate of Western Gas Acquires 20% Ownership InterestHouston area, was placed into full service.   The pipeline had been in limited commercial service since February 2019. The Midland-to-ECHO Pipeline
In June 2018, pursuant to an option agreement, an affiliate of Western Gas Partners, LP (“Western”) acquired a noncontrolling 20% equity interest in our subsidiary, Whitethorn2 Pipeline Company LLC (“Whitethorn”), for approximately $189.6 million in cash.  Whitethorn owns the Midland-to-ECHO Pipeline, whichSystem originates at our Midland Texas terminal and extends 416440 miles to our Sealy Texas facility. Volumesstorage terminal, with volumes arriving at Sealy are then transported to our ECHO terminal using ourthe Rancho II pipeline, which is a component of our South Texas Crude Oil Pipeline System.  Once all infrastructure is complete,We own and operate the Midland-to-ECHO 2 Pipeline will provide Permian Basin producersSystem.

We converted a portion of our Seminole NGL Pipeline system from NGL service to crude oil service to create the Midland-to-Sealy segment of the Midland-to-ECHO 2 Pipeline System. The conversion project was supported by a 10.75-year transportation contract with firm demand fees.  We have the ability to transport multiple gradesconvert this pipeline back to NGL service should market and physical takeaway conditions warrant.

Enterprise Begins Limited Service on the Shin Oak NGL Pipeline

In February 2019, the 24-inch diameter mainline segment of crude oil, including Westthe 658-mile Shin Oak NGL Pipeline from Orla, Texas Intermediate (“WTI”), Light WTI, West Texas Sour and condensate, to Gulf Coast markets. As a resultMont Belvieu was placed into limited commercial service with an initial transportation capacity of infrastructure completed in250 MBPD.  Completion of the related 20-inch diameter Waha lateral is scheduled for the second quarter of 2018 as well as operating enhancements, the pipeline’s transportation capacity is now approximately 575 MBPD.  We report the pipeline’s transportation volumes on a net basis that reflects our 80% interest.

Upon closing of the transaction whereby Western acquired its 20% equity interest in Whitethorn, we credited Western for 20% of the pipeline’s earnings since it was placed into service in November 2017.  We paid Western $45.7 million in June 2018 to settle this obligation.  In addition to Western’s ownership interest in Whitethorn, Western also shares (at a 20% level) in the results of our commercial activities associated with the pipeline.

Apache Dedicates Alpine High NGLs to Enterprise
In May 2018, Apache Corporation (“Apache”) executed a2019.  Supported by long-term supply agreement with us whereby Apache would sell all of its NGL production from the Alpine High discovery to us.  Alpine High is a major hydrocarbon resource located in the Delaware Basin that encompasses rich natural gas (i.e., gas that has a high NGL content), dry natural gas and oil-bearing horizons.  Apache holds approximately 336,000 net acres in the Alpine High discovery.  Enterprise has committed to purchase up to 205 MBPD of NGLs from Apache over the initial ten year term of the supply agreement, the term of which may be extended at the consent of the parties.



In conjunction with the long-term NGL supply agreement, we granted Apache an option to acquire up to a 33% equity interest in our subsidiary that ownscustomer commitments, the Shin Oak NGL Pipeline which is currently under construction and expectedwill ultimately provide up to be placed into service during the second quarter550 MBPD of 2019.  The option is exercisable once the pipeline is placed into commercial service. The Shin Oak NGL Pipeline is designed to transport growing NGL production from the Permian Basin,transportation capacity, which includes the Alpine High discovery, to our NGL fractionation and storage complex located in Mont Belvieu, Texas.  The Shin Oak NGL Pipeline is expected to have an initial design capacity of 550 MBPD.

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

Enterprise and Energy Transfer form Joint Venture to Restore Service on Old Ocean Pipeline
In May 2018, we announced the formation of a 50/50 joint venture with Energy Transfer Partners, L.P. (“Energy Transfer”) to resume full 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.  Energy Transfer serves as operator of the pipeline.Announces $2 Billion Unit Buyback Program

In January 2019, we announced that the Board of Enterprise GP had approved a $2.0 billion multi-year unit buyback program (the “2019 Buyback Program”), which provides the partnership with an additional method to return capital to investors. The Old Ocean Pipeline resumed limited service2019 Buyback Program authorizes the partnership to repurchase its common units from time to time, including through open market purchases and negotiated transactions.  The timing and pace of buy backs under the program will be determined by a number of factors including (i) our financial performance and flexibility, (ii) organic growth and acquisition opportunities with higher potential returns on investment, (iii) our unit price and implied cash flow yield and (iv) maintaining targeted financial leverage with a debt-to-normalized adjusted EBITDA, or earnings before interest, taxes, depreciation and amortization, ratio in the second quarter of 2018.  If fully reconstituted, the Old Ocean Pipeline is expected to provide natural gas transportation capacity of up to 160 MMcf/d by the end of 2018. In addition, both parties are expanding their jointly owned North Texas 36-inch diameter pipeline, which is a component of our Texas Intrastate System, to provide additional natural gas takeaway capacity of 150 MMcf/d from West Texas, including deliveries into the Old Ocean Pipeline.  The North Texas Pipeline expansion project is expected to be complete by late fourth quarter of 2018.

The resumption of full service on the Old Ocean Pipeline and expansion3.5 times area.  No time limit has been set for completion of the North Texas Pipeline are expected to provide producers with additional takeaway capacity to accommodate growing natural gas production from the Delawareprogram, and Midland Basins.

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

The expansions are designed to facilitate growing production of NGLs from domestic shale basins, including the Denver-Julesburg (“DJ”) Basin in Colorado, by providing DJ Basin producers with flow assurance and greater access to the Gulf Coast markets.  The expansions are expected to increase the transportation capacity of Front Range and Texas Express by 100 MBPD and 90 MBPD, respectively.  We anticipate the expansion projects willit may be placed into service during the third quarter of 2019.suspended or discontinued at any time.

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 ofProvides 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.Distribution Guidance

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

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

Enterprise to Expand Butane Isomerization Facility
In January 2018, we2019, management announced plans to expandrecommend to the Board an increase of $0.0025 per unit per quarter in our butane isomerization facility by upcash distribution rate with respect to 30 MBPD2019. The anticipated rate of incremental capacity.   This expansionincrease would result in distributions for 2019 of $1.7650 per unit, which would be 2.3% higher than those paid for 2018 of $1.7250 per unit.  The payment of any quarterly cash distribution is supported by new long-term agreements, including a 20-year, 35 MBPD fee-based, tolling arrangement,subject to provide butane isomerization, storageBoard approval and pipeline services.

(4) The “Indicative Gas Processing Spread” represents a generic estimate of the gross economic benefit from extracting NGLs from natural gas production based on certain pricing assumptions. Specifically, it is the amount by which the assumed economic value of a composite gallon of NGLs at Mont Belvieu, Texas exceeds the value of the equivalent amount of energy in natural gas at Henry Hub, Louisiana (as presented in the table above). The indicative spread does not consider the operating costs incurred by a natural gas processing plant to extract the NGLs nor the transportation and fractionation costs to deliver the NGLs to market. In addition, the actual gas processing spread earned at each plant is determined by regional pricing and extraction dynamics. As presented in the table above, the indicative spread assumes that a gallon of NGLs is comprised of 30% ethane, 35% propane, 12% normal butane, 8% isobutane and 15% natural gasoline. The value of an equivalent amount of energy in natural gas to one gallon of NGLs is assumed to be 8.9% of the price of a MMBtu of natural gas at Henry Hub.

Fluctuations in our consolidated revenues and cost of sales amounts are explained in large part by changes in energy commodity prices.  Energy commodity prices fluctuate for a variety of reasons, including supply and demand imbalances and geopolitical tensions.  The weighted-average indicative market price for NGLs was $0.83$0.66 per gallon in the secondfirst quarter of 20182019 versus $0.60$0.77 per gallon during the secondfirst quarter of 2017.  Likewise, the weighted-average indicative market price for NGLs was $0.80 per gallon during the six months ended June 30, 2018 compared to $0.63 per gallon during the same period in 2017.2018.

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 1413  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.

(1) Amount presented for three and six months ended June 30, 2018 includes $11.8 million and $19.0 million, respectively, of swaption premium income.
(2) We capitalize interest costs incurred on funds used to construct property, plant and equipment while the asset is in its construction phase. Capitalized interest amounts become part of the historical cost of an asset and are charged to earnings (as a component of depreciation expense) on a straight-line basis over the estimated useful life of the asset once the asset enters its intended service. When capitalized interest is recorded, it reduces interest expense from what it would be otherwise. Capitalized interest amounts fluctuate based on the timing of when projects are placed into service, our capital spending levels and the interest rates charged on borrowings.
(3) Primarily reflects facility commitment fees charged in connection with our revolving credit facilities and amortization of debt issuance costs.

Business Segment Highlights

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

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

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

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

Midland-to-ECHO Pipeline and related marketing activities
Gross operating margin from our Crude Oil Pipelines & Services segment for the first quarter of 2019 increased  $442.3 million when compared to the first quarter of 2018.

Gross operating margin from our Midland-to-ECHO 1 Pipeline System and related marketingbusiness activities wasincreased $221.0 million quarter-to-quarter primarily due to changes in non-cash mark-to-market earnings, which were a combined$67.2 million benefit in the first quarter of 2019 compared to a $114.0 million loss in the first quarter of $211.42018, and lower expenses, which accounted for a $28.9 million increase. Gross operating margin for the secondfirst quarter of 2018 was reduced by $24.2 million in connection with the expected allocation of pipeline earnings to Western Gas Partners, LP (“Western”) upon closing of their acquisition of a 20% ownership interest in Whitethorn Pipeline Company LLC (“Whitethorn”), which owns the majority of the Midland-to-ECHO 1 Pipeline System. Western acquired its interest in Whitethorn in June 2018.  Likewise, we recorded a $276.0 million combined loss from this business with respect to the six months ended June 30, 2018.  Transportation volumes for the Midland-to-ECHO 1 Pipeline which entered limited commercial service in November 2017 and full service in April 2018, averaged 436System increased 58 MBPD and 417 MBPD during the three and six months ended June 30, 2018, respectively (net to our interest).quarter-to-quarter.


Gross operating margin for this business forThe mark-to-market earnings attributable to the three and six months ended June 30, 2018 includes non-cash mark-to-market losses of $309.9 million and $423.9 million, respectively,Midland-to-ECHO 1 Pipeline System are associated with the hedging of crude oil commoditymarket price differentials (basis spreads) between the Midland and Houston area markets.  TheseAt March 31, 2019, these hedges, which were primarily entered into throughoutduring 2017, servedserve to lock in an average $2.62a $2.75 per barrel positive margin on our anticipated purchases of crude oil at Midland and subsequent anticipated sales to customers in the Houston area for periods extending predominantly into 2019 and minimally inthrough 2020. The mark-to-market losses recognized during the three and six months ended June 30, 2018 were due to the widening of the basis spreads between Midland and Houston to an average of $14.83 per barrel through 2020 (as of June 30, 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,year-to-year; however, the hedge levels generally correspond to pipeline capacity currently expected to be available to us duringon the first three years of the pipeline’s operationsMidland-to-ECHO 1 Pipeline System as customer commitment volumes ramp up to peak levels.

If  The mark-to-market gain for the first quarter of 2019 reflects a decrease in the basis spreads underlying these hedges widen further, we would be exposedspread between the Midland and Houston markets since December 31, 2018 to additional temporary non-cash mark-to-market losses.  Conversely, if basis spreads narrow in the future reverting back towards or below thean average $2.62of $4.51 per barrel spread we originally locked in, then we would recognize temporary non-cash mark-to-market gains in future periods.through 2020 relative to our average hedged amount of $2.75 per barrel across these same periods (as of March 31, 2019).  When the forecasted physical receipts and deliveries of crude oil ultimately occur in the future, we will realize a physical gross margin at then prevailingthen-prevailing commodity price spreads; however the realized settlement of the associated financial hedges shouldwould convert that physical margin to the average $2.62$2.75 per barrel spread of the financial hedges.  At that time, the unrealized mark-to-market losses recognized in the three and six months ended June 30, 2018 and in future periods until the physical deliveries occur will be reversed, thus eliminating their impact to cumulative earnings recognized over the entire life-to-date period of the hedge.

The basis spread between the Midland and Houston markets continues to fluctuate.  We also have uncommitted capacity on the pipeline that could provide us with potential upside to widening or downside to narrowing market spreads. 

For information regarding the impact of these spreads on our crude oil marketing hedging portfolio, see Item 3, Quantitative and Qualitative Disclosures about Market Risk, within this Part I, Item 2.  For general information regarding our derivative instruments andcommodity hedging activities, see Note 1413 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 three and six months ended June 30, 2018 was also reduced by $9.8 million and $33.9 million, respectively, in connection with the allocation of pipeline earnings to Western upon closing of their acquisition of a noncontrolling 20% equity interest in the pipeline on June 1, 2018.  For additional information regarding this transaction, see “Significant Recent Developments” within this Part I, Item 2.

Other crude oil pipelines, terminals and marketing results
Second Quarter of 2018 Compared to Second Quarter of 2017. Gross operating margin from our other crude oil pipelines, terminals and related marketing activities increased $132.5 million primarily due to higher average sales margins, which accounted for an $83.6 million increase, and higher non-cash mark-to-market earnings, which accounted for an additional $48.1 million increase.  Non-cash mark-to-market earnings for this business was a gain of $32.6 million during the secondfirst quarter of 2018 increased $27.5 million when2019 compared to a loss of $15.5 million during the secondfirst quarter of 2017.2018.  The higher crude oil marketing earnings relate to higher market price differentials for crude oil between the Permian Basin region, Cushing hub and Gulf Coast markets.

Gross operating margin from our SouthWest Texas Crude Oil Pipeline System increased a net $21.5 million quarter-to-quarter primarily due to higher transportation volumes, which accounted for $11.1 million of the increase, and higher firm capacity reservation fees associated with the Midland-to-ECHO Pipeline, which accounted for an additional $12.1 million of the increase, partially offset by lower average transportation fees, which accounted for a $9.2 million decrease.  Crude oil transportation volumes for this system increased 34 MBPD quarter-to-quarter.

Gross operating margin from our crude oil marketing activities, excluding those attributable to ourMidland-to-ECHO 2 Pipeline System, which was in limited commercial activities onservice during the Midland-to-ECHO Pipeline, decreased $25.6 million quarter-to-quarter primarily due to non-cash mark-to-market losses of $28.1 million in the secondfirst quarter of 2018 compared to non-cash mark-to-market gains2019, was $17.4 million on transportation volumes of $14.9 million in the second quarter of 2017. The mark-to-market losses recognized by this business in the second quarter of 2018 are related to the widening of crude oil commodity prices differentials between the Midland, Texas and Cushing, Oklahoma markets.

147 MBPD.  Gross operating margin from our equity investment in the Seaway Pipeline decreased $7.2increased $22.4 million quarter-to-quarter primarily due to a decrease in long-haul transportation revenues attributable to an increase in walk-up shipper volumes, which are charged a lower tariff.  Overall, transportation volumes on the Seaway Pipeline increased 47 MBPD quarter-to-quarter (net to our interest).   Crude oil exports from Seaway’s dock facilities increased 76 MBPD quarter-to-quarter (net to our interest), which includes the loading of a VLCC tanker at Seaway’s Texas City terminal in June 2018.  See “Significant Recent Developments” within this Part I, Item 2 for information regarding our recent operations and projects involving VLCC ships.

Six Months Ended June 30, 2018 Compared to Six Months Ended June 30, 2017.  Gross operating margin from our other crude oil pipelines, terminals and related marketing activities for the six months ended June 30, 2018 increased $47.5 million when compared to the six months ended June 30, 2017.

In September 2017, EPO entered into a 364-Day Credit Agreement that matures in September 2018 and allows EPO to borrow up to $1.5 billion in revolving loans at a variable interest rate for a term of 364 days.   EPO expects to renew its 364-Day Credit Agreement during the third quarter of 2018 to extend its maturity date to September 2019. At June 30, 2018, there were no principal amounts outstanding under the existing 364-Day Credit Agreement.

Expected Redemption of Junior Subordinated Notes A
In July 2018, EPO notified its trustee and paying agent to redeem all of the $521.1 million outstanding principal amount of EPO’s Junior Subordinated Notes A.  These notes are redeemable at EPO’s election at par (i.e., at a redemption price equal to the outstanding principal amount of such notes to be redeemed, plus accrued and unpaid interest thereon).   On a short term basis, the redemption of EPO’s Junior Subordinated Notes A is expected to be made using proceeds from the issuance of short term notes under EPO’s commercial paper program or borrowings under its revolving credit facilities. The average variable interest rate paid on the Junior Subordinated Notes A for the six months ended June 30, 2018 was 5.61%.  These notes bear a floating rate of three-month LIBOR plus approximately 3.7% and represent our highest cost variable-rate debt.


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

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.

Three months ended March 31, 2018:      
Common units issued in connection with DRIP and EUPP  6,642,286  $177.0 
Three months ended June 30, 2018:        
Common units issued in connection with DRIP and EUPP  3,234,804   84.0 
   Total common units issued during the six months ended June 30, 2018  9,877,090  $261.0 


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 June 30, 2018, we have the capacity to issue an additional 71,108,301 common units under this plan.

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

In addition to the DRIP, we have registration statements on file with the SEC in connection with our EUPP.  After taking into account the number of common units issued under the EUPP through June 30, 2018, we have the capacity to issue an additional 5,492,560 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 six months ended June 30, 2018.  After taking into account the aggregate sales price of common units sold under the ATM program in periods prior to fiscal 2018, we have the capacity to issue additional common units under the ATM program up to an aggregate sales price of $2.54 billion.

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

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

Restricted Cash

Restricted cash represents amounts held in segregated bank accounts by our clearing brokers as margin in support of our commodity derivative instruments portfolio and related physical purchases and sales of natural gas, NGLs, crude oil and refined products.  At June 30, 2018 and December 31, 2017, our restricted cash amounts were $283.6 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 August 1, 2018,At May 8, 2019, the investment-grade credit ratings of EPO’s long-term senior unsecured debt securities were BBB+ from Standard and Poor’s, Baa1 from Moody’s and BBB+ from Fitch Ratings.  In addition, the credit ratings of EPO’s short-term senior unsecured debt securities were A-2 from Standard and Poor’s, P-2 from Moody’s and F-2 from Fitch Ratings.

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

Issuance of Common Units under DRIP and EUPP

We issued a combined 1,516,779 common units in the first quarter of 2019 in connection with our distribution reinvestment plan (“DRIP”) and employee unit purchase plan (“EUPP”).  In total, the net cash proceeds we received from these issuances was $42.7 million.  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.

Non-GAAP Cash Distributions to Limited PartnersFlow Measures

Distributable Cash Flow
Our partnership agreement requires us to make quarterly distributions to our unitholders of all available cash, after any cash reserves established by Enterprise GP in its sole discretion.  Cash reserves include those for the proper conduct of our business, including for example, those for capital expenditures, debt service, working capital, operating expenses, common unit repurchases, 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 “distributabledistributable cash flow (“DCF”), which is a non-GAAP liquiditycash flow measure.  Distributable cash flowDCF 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 declared quarterly cash distributions.  Distributable cash flowDCF is also a quantitative standard used by the investment community with respect to publicly traded partnerships becausesince 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 flowDCF we generate to the cash distributions we expect to pay our partners.  Using this metric, management computes our distribution coverage ratio.  Our calculation of DCF may or may not be comparable to similarly titled measures used by other companies.

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

Our use of distributable cash flowDCF 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”Flow Statement Highlights” within this Part I, Item 2.

Free Cash Flow
Free Cash Flow (“FCF”), a non-GAAP financial measure, is a traditional cash flow metric that is widely used by a variety of investors and other participants in the financial community, as opposed to DCF, which is a cash flow measure primarily used by investors and others in evaluating master limited partnerships. In general, FCF is a measure of how much cash flow a business generates during a specified time period after accounting for all capital investments, including expenditures for growth and sustaining capital projects. By comparison, only sustaining capital expenditures are reflected in DCF.

We believe that FCF is important to traditional investors since it reflects the amount of cash available for reducing debt, investing in additional capital projects, paying distributions, common unit repurchases and similar matters.  Since business partners fund certain capital projects of our consolidated subsidiaries, our determination of FCF reflects the amount of cash we receive from noncontrolling interests, net of any distributions paid to such interests.  Our calculation of FCF may or may not be comparable to similarly titled measures used by other companies.

Our use of FCF for the limited purposes described above and in this report is not a substitute for net cash flows provided by operating activities, which is the most comparable GAAP measure.

FCF fluctuates based on our earnings, the level of investing activities we undertake each period, and the timing of operating cash receipts and payments.  In addition to providing the quarterly amounts presented below, we also provide a calculation of aggregate FCF over the twelve months ended March 31, 2019 in order to measure FCF over a longer term. The following table summarizes our calculation of FCF for the periods indicated (dollars in millions):

Capital SpendingInvestments

We currently have approximately $5.2$5.0 billion of growth capital projects scheduled to be completed by the end of 2019.  These projects include the:mid-2020 including:

§the completion of joint venture-owned dock infrastructure in Corpus Christi designed to accommodate crude oil volumes (third(second quarter of 2018);2019),

§completion of
the Shin Oak NGL Pipelinethird processing train at our Orla natural gas processing facility (second quarter of 2019);,


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

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

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

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

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


§our Mentone cryogenic natural gas processing plant (first quarter of 2020), and
Our PDH facility completed its commissioning (or start up) phase and was placed into full commercial service in the second quarter
60



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

Based on information currently available, we expect our total growth capital spendinginvestments for 20182019 to approximate $3.8 billion to $4.0$4.2 billion, which includes the $150.6reflects growth capital expenditures of $3.4 billion to $3.8 billion and $350 million we spent to acquire the remaining 50% equity interest in Delaware Processing.  We expect ourfor sustaining capital expenditures for 2018 to approximate $315 million, of which $140.4 million was spent in the six months ended June 30, 2018.expenditures.

Our forecast of capital spendinginvestments for 20182019 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 spendinginvestments due to factors beyond our control, such as adverse economic conditions, weather related issues and changes in supplier prices.  Furthermore, our forecast of capital spendinginvestments 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 venturespartnering with other companies to share costs and risks, continues to be a significant factor in determining how much capital we can invest.  We believe our access to capital resources is sufficient to meet the demands of our current and future growth needs and, although we expect to make the forecast capital expenditures noted above, we may adjust the timing and amounts of projected expenditures in response to changes in capital market conditions.

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 sixthree months ended June 30, 2018March 31, 2019 involved projects to support crude oil, natural gas and NGL production from the Permian Basin, export activities at our Gulf Coast terminalterminals and spending on our iBDH unit.  Fluctuations in spending for sustaining capital projects are explained in large part by the timing and cost of pipeline integrity and similar projects.

Critical Accounting Policies and Estimates

A discussion of our critical accounting policies and estimates is included in our 20172018 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.

ItemITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURESQuantitative and Qualitative Disclosures About Market Risk.
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 1413 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.

At June 30, 2018,March 31, 2019, our predominant commodity hedging strategies consisted of (i) hedging anticipated future purchases and sales of commodity products associated with transportation, storage and blending activities, (ii) hedging natural gas processing margins and (iii) hedging the fair value of commodity products held in inventory.  

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

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

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

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

The derivative liability for our crude oil marketing hedges increased from $65.5 million at Decemberdecreased since March 31, 2017 to $521.6 million at June 30, 2018, which resulted in a $456.1 million decrease in the fair value of the crude oil marketing portfolio for the six months ended June 30, 2018. The derivative liability for the portfolio improved to $477.5 million at July 16, 20182019 primarily due to the expiration of basis swap instruments since June 30, 2018.  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 thehigher crude oil commodity price differentials between the Midland and Houston markets and the Midland and Cushing markets.  The mark-to-market losses we recognized during the three and six months ended June 30, 2018 were primarily due to the widening of the basis spreads between the Midland and Houston and Cushing markets.

Assuming no changes subsequent to June 30, 2018 in the variables underlying the portfolio’s fair value, the derivative liability of $521.6 million at June 30, 2018 would be reversed upon cash settlement of the hedges, which would create unrealized mark-to-market gains and other comprehensive income as follows in the periods indicated (dollars in millions):

Third quarter of 2018 $158.8 
Fourth quarter of 2018  198.5 
Calendar year 2019  142.6 
Calendar year 2020  6.2 
Total mark-to-market gains $506.1 
Total other comprehensive income  15.5 
Total comprehensive income $521.6 


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

At June 30, 2018, approximately 50% of the Midland-to-ECHO Pipeline’s uncommitted capacity available to us through 2020 was not hedged, thus providing us with potential upside to widening or downside to narrowing market spreads.   The value of this unhedged capacity was approximately $363.8 million assuming that we hedged all such capacity at the prevailing crude oil commodity price differentials between Midland and Houston as of June 30, 2018.

The posting of additional cash may be required to maintain our commodity derivative instruments portfolio as prices fluctuate or margin requirements change.  Our restricted cash balance increased from $283.6 million at June 30, 2018 to $316.0 million at July 16, 2018.  In addition, we posted $238.3 million of cash and $85.0 million under stand-by letters of credit in connection with margin requirements on the Chicago Mercantile Exchange through July 16, 2018. The increase in restricted cash and other cash postings since June 30, 2018 is primarily due to changes in the initial margin requirements and fair value of our crude oil marketing transportation hedges.prices.

Interest Rate Hedging Activities

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

With respect to the tabular data below, the portfolio’s estimated economic value at a given date is based on a number of factors, including the number and types of derivatives We have no interest rate hedging instruments outstanding at that date, the notional valueas of the swaps and
associated interest rates.filing date of this quarterly report.


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

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

In January 2018, we sold swaptions related to our interest rate hedging activities that resulted in the recognition of $7.2 million of cash gains that were reflected as a reduction in interest expense for the first quarter of 2018.  Likewise, in April 2018, we sold swaptions related to our interest rate hedging activities that resulted in the recognition of $11.8 million of cash gains that were reflected as a reduction in interest expense for the second quarter of 2018.  The January 2018 swaptions expired in March 2018 and the April 2018 swaptions expired in June 2018.

PART II.  OTHER INFORMATION

Item 1. 
Legal ProceedingsITEM 1.  LEGAL PROCEEDINGS..

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

In February 2018, we received a Notice of Violation from the New Mexico Environment Department (“NMED”) for air permit violations at our South Eddy Cryo Plant in New Mexico. Based on subsequent discussions with the NMED, the eventual resolution of this matter may result in monetary sanctions in excess of $0.1 million. We do not expect such expenditures to be material to our consolidated financial statements.

For additional information regarding our litigation matters, see “Litigation” under Note 1615 of the Notes to Unaudited Condensed Consolidated Financial Statements included under Part I, Item 1 of this quarterly report, which subsection is incorporated by reference into this Part II, Item 1.
