ENTERPRISE PRODUCTS PARTNERS L.P.
NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
Our integrated midstream energy asset network links producers of natural gas, NGLs and crude oil from some of the largest supply basins in the United States ("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 import and export terminals (including liquefied petroleum gas or "LPG"); crude oil gathering, transportation, storage and terminals; petrochemical and refined products transportation, storage and terminals, and related services; and a marine transportation business that operates primarily on the U.S. inland and Intracoastal Waterway systems. Our assets currently include approximately 49,000 miles of pipelines; 250 million barrels ("MMBbls") of storage capacity for NGLs, crude oil, petrochemicals and refined products; and 14 billion cubic feet ("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. See Note 13 for information regarding the ASA and other related party matters.
Our historical operations are reported under five business segments: (i) NGL Pipelines & Services, (ii) Crude Oil Pipelines & Services, (iii) Natural Gas Pipelines & Services, (iv) Petrochemical & Refined Products Services and (v) Offshore Pipelines & Services. On July 24, 2015, we completed the sale of our Offshore Business, which primarily consisted of our Offshore Pipelines & Services segment. Our consolidated financial statements reflect ownership of the Offshore Business through July 24, 2015. See Note 9 for additional information regarding our business segments.
As a result of our acquisition of the member interests of EFS Midstream effective July 1, 2015, we began consolidating the financial statements of EFS Midstream as of that date.
Effective January 1, 2016, we applied the provisions of Accounting Standard Update ("ASU") 2015-03, Simplifying the Presentation of Debt Issuance Costs, which requires bond issuance costs to be presented on the balance sheet as a deduction from the carrying value of the associated debt. The guidance was applied on a retrospective basis; therefore, we adjusted our December 31, 2015 consolidated balance sheet to reflect the reclassification of $14.7 million of bond issuance costs from prepaid and other current assets and $135.1 million from other assets to reduce the carrying amount of long-term debt by an aggregate $149.8 million. See Note 7 for additional information regarding our long-term debt.
Note 2. General Accounting and Disclosure Matters
Our results of operations for the three months ended March 31, 2016 are not necessarily indicative of results expected for the full year of 2016. In our opinion, the accompanying Unaudited Condensed Consolidated Financial Statements include all adjustments consisting of normal recurring accruals necessary for fair presentation. Although we believe the disclosures in these financial statements are adequate and make the information presented not misleading, certain information and footnote disclosures normally included in annual financial statements prepared in accordance with U.S. generally accepted accounting principles ("GAAP") have been condensed or omitted pursuant to the rules and regulations of the U.S. Securities and Exchange Commission ("SEC").
These Unaudited Condensed Consolidated Financial Statements and Notes thereto should be read in conjunction with the Audited Consolidated Financial Statements and Notes thereto included in our annual report on Form 10-K for the year ended December 31, 2015 (the "2015 Form 10-K") filed with the SEC on February 26, 2016.

Contingencies
Certain conditions may exist as of the date our consolidated financial statements are issued, which may result in a loss to us but which will only be resolved when one or more future events occur or fail to occur. Management has regular quarterly litigation reviews, including updates from legal counsel, to assess the need for accounting recognition or disclosure of these contingencies, and such assessment inherently involves an exercise in judgment. In assessing loss contingencies related to legal proceedings that are pending against us or unasserted claims that may result in such proceedings, our management and legal counsel evaluate the perceived merits of any legal proceedings or unasserted claims as well as the perceived merits of the amount of relief sought or expected to be sought therein.
We accrue an undiscounted liability for those contingencies where the incurrence of a loss is probable and the amount can be reasonably estimated. If a range of amounts can be reasonably estimated and no amount within the range is a better estimate than any other amount, then the minimum of the range is accrued. We do not record a contingent liability when the likelihood of loss is probable but the amount cannot be reasonably estimated or when the likelihood of loss is believed to be only reasonably possible or remote. For contingencies where an unfavorable outcome is reasonably possible and the impact would be material to our consolidated financial statements, we disclose the nature of the contingency and, where feasible, an estimate of the possible loss or range of loss.
Loss contingencies considered remote are generally not disclosed unless they involve guarantees, in which case the guarantees would be disclosed. See Note 14 for additional information regarding our contingencies.
Derivative Instruments
We use derivative instruments such as futures, swaps, options, forward contracts and other arrangements to manage price risks associated with inventories, firm commitments, interest rates and certain anticipated future commodity transactions. To qualify for hedge accounting, the hedged item must expose us to risk and the related derivative instrument must reduce the exposure to that risk and meet specific hedge documentation requirements related to designation dates, expectations for hedge effectiveness and the probability that hedged future transactions will occur as forecasted. We formally designate derivative instruments as hedges and document and assess their effectiveness at inception of the hedge and on a monthly basis thereafter. Forecasted transactions are evaluated for the probability of occurrence and are periodically back-tested once the forecasted period has passed to determine whether similarly forecasted transactions are probable of occurring in the future.
For certain physical forward commodity derivative contracts, we apply the normal purchase/normal sale exception, whereby changes in the mark-to-market values of such contracts are not recognized in income. As a result, the revenues and expenses associated with such physical transactions are recognized during the period when volumes are physically delivered or received. Physical forward commodity contracts subject to this exception are evaluated for the probability of future delivery and are periodically back-tested once the forecasted period has passed to determine whether similar forward contracts are probable of physical delivery in the future. See Note 12 for additional information regarding our derivative instruments.
Estimates
Preparing our consolidated financial statements in conformity with U.S. GAAP requires us to make estimates that affect amounts presented in the financial statements. Our most significant estimates relate to (i) the useful lives and depreciation/amortization methods used for fixed and identifiable intangible assets; (ii) measurement of fair value and projections used in impairment testing of fixed and intangible assets (including goodwill); (iii) contingencies; and (iv) revenue and expense accruals.
Actual results could differ materially from our estimates. On an ongoing basis, we review our estimates based on currently available information. Any changes in the facts and circumstances underlying our estimates may require us to update such estimates, which could have a material impact on our consolidated financial statements.

Fair Value Measurements
Our fair value estimates are based on either (i) actual market data or (ii) assumptions that other market participants would use in pricing an asset or liability, including estimates of risk, in the principal market of the asset or liability at a specified measurement date. Recognized valuation techniques employ inputs such as contractual prices, quoted market prices or rates, operating costs, discount factors and business growth rates. These inputs may be either readily observable, corroborated by market data or generally unobservable. In developing our estimates of fair value, we endeavor to utilize the best information available and apply market-based data to the highest extent possible. Accordingly, we utilize valuation techniques (such as the market approach) that maximize the use of observable inputs and minimize the use of unobservable inputs.
A three-tier hierarchy has been established that classifies fair value amounts recognized in the financial statements based on the observability of inputs used to estimate such fair values. The hierarchy considers fair value amounts based on observable inputs (Levels 1 and 2) to be more reliable and predictable than those based primarily on unobservable inputs (Level 3). At each balance sheet reporting date, we categorize our financial assets and liabilities using this hierarchy.
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. Additional cash may be restricted to maintain our commodity derivative instruments portfolio as prices fluctuate or deposit requirements change. At March 31, 2016 and December 31, 2015, our restricted cash amounts were $136.9 million and $15.9 million, respectively. See Note 12 for information regarding our derivative instruments and hedging activities.
Note 3. Inventories
Our inventory amounts by product type were as follows at the dates indicated:

|  | March 31, 2016 |  |  | December 31, 2015 |
NGLs |  | $ | 625.8 |  |  | $ | 639.9 |
Petrochemicals and refined products |  |  | 335.7 |  |  |  | 148.0 |
Crude oil |  |  | 248.7 |  |  |  | 222.1 |
Natural gas |  |  | 21.9 |  |  |  | 28.1 |
Total |  | $ | 1,232.1 |  |  | $ | 1,038.1 |

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

|  | For the Three Months Ended March 31, |
|  | 2016 |  |  | 2015 |
Cost of sales (1) |  | $ | 3,208.3 |  |  | $ | 5,678.1 |
Lower of cost or market adjustments |  |  | 5.3 |  |  |  | 3.5 |
(1) Cost of sales is a component of "Operating costs and expenses" as presented on our Unaudited Condensed Statements of Consolidated Operations. Fluctuations in these amounts are primarily due to changes in energy commodity prices and sales volumes associated with our marketing activities. |

Property, plant and equipment, net |  |  |  |  |  | $ | 32,673.3 |  |  | $ | 32,034.7 |
(1) Plants, pipelines and facilities include processing plants; NGL, natural gas, crude oil and petrochemical and refined products pipelines; terminal loading and unloading facilities; buildings; office furniture and equipment; laboratory and shop equipment and related assets. (2) Underground and other storage facilities include underground product storage caverns; above ground storage tanks; water wells and related assets. (3) Transportation equipment includes tractor-trailer tank trucks and other vehicles and similar assets used in our operations. (4) Marine vessels include tow boats, barges and related equipment used in our marine transportation business. (5) In general, the estimated useful lives of major assets within this category are: processing plants, 20-35 years; pipelines and related equipment, 5-45 years; terminal facilities, 10-35 years; buildings, 20-40 years; office furniture and equipment, 3-20 years; and laboratory and shop equipment, 5-35 years.

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

|  | For the Three Months Ended March 31, |
|  | 2016 |  |  | 2015 |
Depreciation expense (1) |  | $ | 295.9 |  |  | $ | 291.3 |
Capitalized interest (2) |  |  | 42.5 |  |  |  | 29.6 |
(1) Depreciation expense is a component of "Costs and expenses" as presented on our Unaudited Condensed Statements of Consolidated Operations. (2) We capitalize interest costs incurred on funds used to construct property, plant and equipment while the asset is in its construction phase. The capitalized interest is recorded as part of the asset to which it relates and is amortized over the asset's estimated useful life as a component of depreciation expense. When capitalized interest is recorded, it reduces interest expense from what it would be otherwise. |

Asset Retirement Obligations
We record asset retirement obligations ("AROs") in connection with legal requirements to perform specified retirement activities under contractual arrangements and/or governmental regulations. Our contractual AROs primarily result from right-of-way agreements associated with our pipeline operations and real estate leases associated with our plant sites. In addition, we record AROs in connection with governmental regulations associated with the abandonment or retirement of above-ground brine storage pits and certain marine vessels. We also record AROs in connection with regulatory requirements associated with the renovation or demolition of certain assets containing hazardous substances such as asbestos. We typically fund our AROs using cash flow from operations.
Property, plant and equipment at March 31, 2016 and December 31, 2015 includes $17.5 million and $17.6 million, respectively, of asset retirement costs capitalized as an increase in the associated long-lived asset.

Parent-Subsidiary Guarantor Relationships
Enterprise Products Partners L.P. acts as guarantor of the consolidated debt obligations of EPO, with the exception of the remaining debt obligations of TEPPCO. If EPO were to default on any of its guaranteed debt, Enterprise Products Partners L.P. would be responsible for full and unconditional repayment of that obligation.
Issuance of $1.25 Billion of Senior Notes in April 2016
In April 2016, EPO issued $575 million in principal amount of 2.85% senior notes due April 2021 ("Senior Notes RR"), $575 million in principal amount of 3.95% senior notes due February 2027 ("Senior Notes SS") and $100 million in principal amount of 4.90% reopened senior notes due May 2046 ("Senior Notes QQ"). Senior Notes RR, SS and QQ were issued at 99.898%, 99.760% and 95.516% of their principal amounts, respectively. We issued these senior notes using our 2013 Shelf (see Note 8).
Net proceeds from the issuance of these senior notes were used as follows: (i) the repayment of amounts then outstanding under EPO's commercial paper program, which included amounts we used to repay $750 million in principal amount of Senior Notes AA that matured in February 2016, and (ii) for general company purposes.
Enterprise Products Partners L.P. has unconditionally guaranteed these senior notes on an unsecured and unsubordinated basis. These senior notes rank equal with EPO's existing and future unsecured and unsubordinated indebtedness and are senior to any existing and future subordinated indebtedness of EPO. These senior notes are subject to make-whole redemption rights and were issued under an indenture containing certain covenants, which generally restrict EPO's ability (with certain exceptions) to incur debt secured by liens and engage in sale and leaseback transactions.
Letters of Credit
At March 31, 2016, EPO had $2.5 million of letters of credit outstanding related to operations at our facilities and motor fuel tax obligations.
Lender Financial Covenants
We were in compliance with the financial covenants of our consolidated debt agreements at March 31, 2016.
Information Regarding Variable Interest Rates Paid
The following table presents the range of interest rates and weighted-average interest rates paid on our consolidated variable-rate debt during the three months ended March 31, 2016:

| Range of Interest Rates Paid | Weighted-Average Interest Rate Paid
Commercial Paper Notes | 0.56% to 1.18% | 0.89%
Multi-Year Revolving Credit Facility | 1.43% to 1.43% | 1.43%

Note 8. Equity and Distributions
Partners Equity
Partners' equity reflects the limited partner interests (i.e., common units, including restricted common units) that we have outstanding. The following table summarizes changes in the number of our outstanding units from December 31, 2015 to March 31, 2016:

|  | Common Units (Unrestricted) |  |  | Restricted Common Units |  |  | Total Common Units |
Number of units outstanding at December 31, 2015 |  |  | 2,010,592,504 |  |  |  | 1,960,520 |  |  |  | 2,012,553,024 |

Common units issued in connection with DRIP and EUPP |  |  | 7,282,006 |  |  |  | -- |  |  |  | 7,282,006 |
Common units issued in connection with the vesting of phantom unit awards |  |  | 1,053,117 |  |  |  | -- |  |  |  | 1,053,117 |
Common units issued in connection with the vesting of restricted common unit awards |  |  | 1,167,578 |  |  |  | (1,167,578 | ) |  |  | -- |
Forfeiture of restricted common unit awards |  |  | -- |  |  |  | (9,350 | ) |  |  | (9,350 | )

The net cash proceeds we received from the issuance of common units during the three months ended March 31, 2016 were used to temporarily reduce amounts outstanding under EPO's commercial paper program and revolving credit facilities and for general company purposes.
Universal shelf registration statement
We expect to issue additional equity and debt securities to assist us in meeting our future liquidity requirements, including those related to capital spending. We have a universal shelf registration statement (the "2013 Shelf") on file with the SEC. The 2013 Shelf allows Enterprise Products Partners L.P. and EPO (each on a standalone basis) to issue an unlimited amount of equity and debt securities, respectively. See Note 7 for information regarding an offering of senior notes we completed in April 2016 using the 2013 Shelf.
The 2013 Shelf will expire in June 2016, at which time we expect to file a replacement universal shelf registration statement.
ATM program
We have a registration statement on file with the SEC in connection with our "at-the-market" program (or "ATM program"). Pursuant to this program, we may sell common units under an equity distribution agreement between Enterprise Products Partners L.P. and certain broker-dealers from time-to-time by means of ordinary brokers' transactions through the NYSE at market prices, in block transactions or as otherwise agreed to with the broker-dealer parties to the agreement.
During the three months ended March 31, 2016, we sold 35,396,147 common units under the ATM program for aggregate gross proceeds of $856.5 million. This includes 3,830,256 common units sold in January 2016 to privately held affiliates of EPCO, which generated gross proceeds of $100 million. After taking into account applicable costs, our transactions under the ATM program resulted in aggregate net cash proceeds of $849.0 million during the three months ended March 31, 2016. During the three months ended March 31, 2015, we issued 12,350,761 common units under this program for aggregate gross cash proceeds of $407.8 million, resulting in total net cash proceeds of $404.2 million.
During the period April 1, 2016 through April 8, 2016, we sold an additional 25,550,931 common units under the ATM program for aggregate gross proceeds of $594.1 million, resulting in net cash proceeds of $592.0 million. After taking into account the aggregate sales price of common units sold under our ATM program through April 8, 2016, our capacity under the applicable registration statement was reduced to $415.7 million. On April 22, 2016, we filed a registration statement with the SEC that (when declared effective) will replace our existing registration statement with respect to the ATM program and increase the available capacity under the ATM program to allow us to issue up to an aggregate $2.17 billion of additional common units, inclusive of the remaining capacity under such existing registration statement.

Distribution reinvestment plan
We also have registration statements on file with the SEC collectively authorizing the issuance of up to 140,000,000 of our common units in connection with a distribution reinvestment plan ("DRIP"). The DRIP provides unitholders of record and beneficial owners of our common units a voluntary means by which they can increase the number of our common units they own by reinvesting the quarterly cash distributions they receive from us into the purchase of additional new common units. We issued a total of 7,162,744 common units under our DRIP during the three months ended March 31, 2016, which generated net cash proceeds of $159.8 million. During the three months ended March 31, 2015, we issued 1,869,079 common units under our DRIP, which generated net cash proceeds of $61.7 million. Privately held affiliates of EPCO reinvested $100 million through the DRIP during the three months ended March 31, 2016 (this amount being a component of the net cash proceeds presented). After taking into account the number of common units issued under the DRIP through March 31, 2016, we have the capacity to issue an additional 7,905,254 common units under this plan. We expect to file a new registration statement during the second quarter of 2016 to increase the number of common units available for issuance under the DRIP.
Employee unit purchase plan
In addition to the DRIP, we have registration statements on file with the SEC authorizing the issuance of up to 8,000,000 of our common units in connection with our employee unit purchase plan ("EUPP"). We issued 119,262 common units under our EUPP during the three months ended March 31, 2016, which generated net cash proceeds of $2.7 million. During the three months ended March 31, 2015, we issued 71,753 common units under our EUPP, which generated net cash proceeds of $2.5 million. After taking into account the number of common units issued under the EUPP through March 31, 2016, we may issue an additional 6,653,244 common units under this plan.
Noncontrolling Interests
Noncontrolling interests represent third party equity ownership interests in our consolidated subsidiaries.

2016: |  |  |  |  |  |
1st Quarter |  | $ | 0.3950 |  | 4/29/2016 | 5/6/2016

In November 2010, we completed our merger with Enterprise GP Holdings L.P. (the "Holdings Merger"). In connection with the Holdings Merger, a privately held affiliate of EPCO agreed to temporarily waive the regular cash distributions it would otherwise receive from us with respect to a certain number of our common units it owns (the "Designated Units"). Distributions paid to partners during 2015 excluded 35,380,000 Designated Units. The temporary distribution waiver expired in November 2015; therefore, distributions to be paid, if any, during calendar year 2016 will include all common units owned by the privately held affiliates of EPCO.
Note 9. Business Segments
Our historical operations are reported under five business segments: (i) NGL Pipelines & Services, (ii) Crude Oil Pipelines & Services, (iii) Natural Gas Pipelines & Services, (iv) Petrochemical & Refined Products Services and (v) Offshore Pipelines & 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.
Our consolidated financial statements reflect ownership of the Offshore Business through July 24, 2015, which was the closing date of the sales transaction.
Segment revenues include intersegment and intrasegment transactions, which are generally based on transactions made at market-based rates. Our consolidated revenues reflect the elimination of intercompany transactions. Substantially all of our consolidated revenues are earned in the U.S. and derived from a wide customer base.
We evaluate segment performance based on the non-GAAP financial measure of gross operating margin. Gross operating margin (either in total or by individual segment) is an important performance measure of the core profitability of our operations. This measure forms the basis of our internal financial reporting and is used by our executive management in deciding how to allocate capital resources among business segments. We believe that investors benefit from having access to the same financial measures that our management uses in evaluating segment results. The GAAP financial measure most directly comparable to total segment gross operating margin is operating income.

Table of Contents
ENTERPRISE PRODUCTS PARTNERS L.P.
NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
In total, gross operating margin represents operating income exclusive of (1) depreciation, amortization and accretion expenses, (2) impairment charges, (3) gains and losses attributable to asset sales and (4) general and administrative costs. Gross operating margin includes equity in income of unconsolidated affiliates and non-refundable deferred transportation revenues relating to the make-up rights of committed shippers associated with certain pipelines. Gross operating margin by segment is calculated by subtracting segment operating costs and expenses (net of the adjustments noted above) from segment revenues, with both segment totals before the elimination of intercompany transactions. In accordance with GAAP, intercompany accounts and transactions are eliminated in consolidation. 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.
Segment assets consist of property, plant and equipment, investments in unconsolidated affiliates, intangible assets and goodwill. The carrying values of such amounts are assigned to each segment based on each asset's or investment's principal operations and contribution to the gross operating margin of that particular segment. Since construction-in-progress amounts (a component of property, plant and equipment) generally do not contribute to segment gross operating margin, such amounts are excluded from segment asset totals until the underlying assets are placed in service. Intangible assets and goodwill are assigned to each segment based on the classification of the assets to which they relate. Substantially all of our plants, pipelines and other fixed assets are located in the U.S. The remainder of our consolidated total assets, which consist primarily of working capital assets, are excluded from segment assets since these amounts are not attributable to one specific segment (e.g. cash).

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

Diluted earnings per unit |  | $ | 0.32 |  |  | $ | 0.32 |
(1) Each phantom unit award includes a DER, which entitles the recipient to receive cash payments equal to the product of the number of phantom unit awards and the cash distribution per unit paid to our common unitholders. Cash payments made in connection with DERs are nonforfeitable. As a result, the phantom units are considered participating securities for purposes of computing basic earnings per unit. |

Note 11. Equity-Based Awards
An allocated portion of the fair value of EPCO's equity-based awards is charged to us under the ASA. The following table summarizes compensation expense we recognized in connection with equity-based awards for the periods indicated:

|  | For the Three Months Ended March 31, |
|  | 2016 |  |  | 2015 |
Equity-classified awards: |  |  |  |  |  |
Phantom unit awards |  | $ | 19.4 |  |  | $ | 17.2 |
Restricted common unit awards |  |  | 2.2 |  |  |  | 6.1 |

Liability-classified awards |  |  | 0.1 |  |  |  | 0.1 |
Total |  | $ | 22.4 |  |  | $ | 23.4 |

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

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
At March 31, 2016, EPCO's significant long-term incentive plans applicable to us were the Enterprise Products 1998 Long-Term Incentive Plan ("1998 Plan") and the 2008 Enterprise Products Long-Term Incentive Plan (Third Amendment and Restatement) ("2008 Plan"). Up to 14,000,000 of our common units may be issued as awards under the 1998 Plan. The maximum number of common units available for issuance under the 2008 Plan was 35,000,000 at March 31, 2016. This amount will automatically increase under the terms of the 2008 Plan by 5,000,000 common units on January 1, 2017 and will continue to automatically increase annually on 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 1998 Plan and 2008 Plan through March 31, 2016, a total of 3,245,652 and 17,981,493 additional common units were available for issuance under these plans, respectively.
In addition, in February 2016, EPCO formed three limited partnerships (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. ("EPD PubCo I"), EPD PubCo Unit II L.P. ("EPD PubCo II") and EPD PrivCo Unit I L.P. ("EPD PrivCo I"). The Employee Partnerships are discussed later in this note.
Phantom Unit Awards
Phantom unit awards allow recipients to acquire our common units (at no cost to the recipient apart from fulfilling service and other conditions) once a defined vesting period expires, subject to customary forfeiture provisions. Phantom unit awards generally vest at a rate of 25% per year beginning one year after the grant date and are non-vested until the required service periods expire.
At March 31, 2016, substantially all of our phantom unit awards are expected to result in the issuance of common units upon vesting; therefore, the applicable awards are accounted for as equity-classified awards. The grant date fair value of a phantom unit award is based on the market price per unit of our common units on the date of grant. Compensation expense is recognized based on the grant date fair value, net of an allowance for estimated forfeitures, over the requisite service or vesting period.
The following table presents phantom unit award activity for the period indicated:

|  | Number of Units |  |  | Weighted- Average Grant Date Fair Value per Unit (1) |
Phantom unit awards at December 31, 2015 |  |  | 5,426,949 |  |  | $ | 33.63 |
Granted (2) |  |  | 4,467,730 |  |  | $ | 21.86 |
Vested |  |  | (1,586,493 | ) |  | $ | 33.56 |
Forfeited |  |  | (41,673 | ) |  | $ | 31.11 |
Phantom unit awards at March 31, 2016 |  |  | 8,266,513 |  |  | $ | 27.29 |
(1) Determined by dividing the aggregate grant date fair value of awards (before an allowance for forfeitures) by the number of awards issued. (2) The aggregate grant date fair value of phantom unit awards issued during 2016 was $97.7 million based on a grant date market price of our common units of $21.86 per unit. An estimated annual forfeiture rate of 3.9% was applied to these awards. |

Our long-term incentive plans provide for the issuance of distribution equivalent rights ("DERs") in connection with phantom unit awards. A DER entitles the participant to nonforfeitable cash payments equal to the product of the number of phantom unit awards outstanding for the participant and the cash distribution per common unit paid to our common unitholders. Cash payments made in connection with DERs are charged to partners' equity when the phantom unit award is expected to result in the issuance of common units; otherwise, such amounts are expensed.
The following table presents supplemental information regarding phantom unit awards for the periods indicated:

|  | For the Three Months Ended March 31, |
|  | 2016 |  |  | 2015 |
Cash payments made in connection with DERs |  | $ | 2.0 |  |  | $ | 1.2 |
Total intrinsic value of phantom unit awards that vested during period |  | $ | 36.3 |  |  | $ | 26.6 |

For the EPCO group of companies, the unrecognized compensation cost associated with phantom unit awards was $145.2 million at March 31, 2016, of which our share of the cost is currently estimated to be $133.1 million. Due to the graded vesting provisions of these awards, we expect to recognize our share of the unrecognized compensation cost for these awards over a weighted-average period of 2.2 years.
Restricted Common Unit Awards
Restricted common 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. Restricted common 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. Restricted common units are included in the number of common units outstanding as presented on our Unaudited Condensed Consolidated Balance Sheets.
The fair value of a restricted common unit award is based on the market price per unit of our common units on the date of grant. Compensation expense is recognized based on the grant date fair value, net of an allowance for estimated forfeitures, over the requisite service or vesting period.
The following table presents restricted common unit award activity for the period indicated:

|  | Number of Units |  |  | Weighted- Average Grant Date Fair Value per Unit (1) |
Restricted common units at December 31, 2015 |  |  | 1,960,520 |  |  | $ | 27.88 |
Vested |  |  | (1,167,578 | ) |  | $ | 27.39 |
Forfeited |  |  | (9,350 | ) |  | $ | 28.32 |
Restricted common units at March 31, 2016 |  |  | 783,592 |  |  | $ | 28.60 |
(1) Determined by dividing the aggregate grant date fair value of awards (before an allowance for forfeitures) by the number of awards issued. |

Each recipient of a restricted common unit award is entitled to nonforfeitable cash distributions equal to the product of the number of restricted common units outstanding for the participant and the cash distribution per unit paid to our common unitholders. These distributions are included in "Cash distributions paid to limited partners" as presented on our Unaudited Condensed Statements of Consolidated Cash Flows.
The following table presents supplemental information regarding restricted common unit awards for the periods indicated:

| For the Three Months Ended March 31, |
| 2016 |  | 2015 |
Cash distributions paid to restricted common unitholders |  | $ | 0.8 |  |  | $ | 1.5 |
Total intrinsic value of restricted common unit awards that vested during period |  | $ | 26.8 |  |  | $ | 62.4 |

For the EPCO group of companies, the unrecognized compensation cost associated with restricted common unit awards was an aggregate $4.7 million at March 31, 2016, of which our share of the cost is currently estimated to be $3.5 million. Due to the graded vesting provisions of these awards, we expect to recognize our share of the unrecognized compensation cost for these awards over a weighted-average period of approximately one year.
Unit Option Awards
EPCO's long-term incentive plans provide for the issuance of non-qualified incentive options denominated in our common units. All of our unit option awards had been exercised as of December 31, 2015 and no new unit option awards were granted during the three months ended March 31, 2016.
In order to fund its unit option award-related obligations, EPCO purchased our common units at fair value directly from us. When employees exercise unit option awards, we reimburse EPCO for the cash difference between the strike price paid by the employee and the actual purchase price paid by EPCO for the units issued to the employee.

Profits Interest Awards
On February 22, 2016, EPCO Holdings Inc. ("EPCO Holdings"), a privately held affiliate of EPCO, contributed the following Enterprise common units it owned to the Employee Partnerships: (i) 2,723,052 units to EPD PubCo I, (ii) 2,834,198 units to EPD PubCo II and (iii) 1,111,438 units to EPD PrivCo I. In exchange for these contributions, EPCO Holdings was admitted as the Class A limited partner of each Employee Partnership. Also on the contribution date, certain key EPCO employees were issued Class B limited partner interests (i.e., profits interest awards) and admitted as Class B limited partners of each Employee Partnership, all without any capital contribution by such employees. EPCO serves as the general partner of each Employee Partnership.
In general, the Class A limited partner earns a preferred return (the "Class A Preference Return," as described below) on its investment (or "Capital Base") in each Employee Partnership, with any residual cash amounts being paid to the Class B limited partners of such Employee Partnership on a quarterly basis. Upon liquidation of an Employee Partnership, assets having a then current fair market value equal to the Class A limited partner's Capital Base in such Employee Partnership, plus any preferred return for the period in which liquidation occurs, will be distributed to the Class A limited partner. Any remaining assets of such Employee Partnership will be distributed to the Class B limited partners of such Employee Partnership as a residual profits interest, which represents the appreciation in value of the Employee Partnership's assets since the date of EPCO Holdings' contribution to it, as described above.
Unless otherwise agreed to by EPCO and a majority in interest of the limited partners of each Employee Partnership, such Employee Partnership will terminate at the earliest to occur of (i) 30 days following its vesting date, (ii) a change of control or (iii) a dissolution of the Employee Partnership. Class B limited partner interests in EPD PubCo I vest four years from February 22, 2016, and Class B limited partner interests in EPD PubCo II and EPD PrivCo I vest five years from that date.
Individually, each Class B limited partner interest is subject to forfeiture if the participating employee's employment with EPCO is terminated prior to vesting, with customary exceptions for death, disability and certain retirements. The risk of forfeiture will also lapse upon certain change of control events. Forfeited individual Class B limited partner interests are allocated to the remaining Class B limited partners.

The following table summarizes key elements of each Employee Partnership:

Employee Partnership | Enterprise Common Units owned by Employee Partnership | Class A Capital Base (1) |  | Class A Partner Preferred Return Rate (2) |  | Expected Liquidation Date | Estimated Grant Date Fair Value of Profits Interest Awards (3) | Unrecognized Compensation Cost (4)
EPD PubCo I | 2,723,052 units | $63.5 million |  |  | 6.6638 | % | Feb. 2020 | $13.2 million | $12.7 million
EPD PubCo II | 2,834,198 units | $66.1 million |  |  | 6.6638 | % | Feb. 2021 | $14.8 million | $14.3 million
EPD PrivCo I | 1,111,438 units | $25.9 million |  |  | 6.6638 | % | Feb. 2021 | $5.8 million | $1.2 million
(1) Represents the fair market value of the Enterprise common units contributed at the contribution date. (2) For each period, the Class A Preference Return equals the Class A Capital Base, after adjusting for certain retained cash distributions and other amounts as defined in the underlying agreements, multiplied by 6.6638% divided by 365 or 366 days, as the case may be during such calendar year, multiplied by the number of days in the applicable period. (3) Represents the total grant date fair value of the profits interest awards irrespective of how such costs will be allocated between us and EPCO and its privately held affiliates. (4) Represents our expected share of the unrecognized compensation cost at March 31, 2016. We expect to recognize our share of the unrecognized compensation cost for EPD PubCo I, EPD PubCo II and EPD PrivCo I over a weighted-average period of 3.9 years, 4.9 years and 4.9 years, respectively.

The grant date fair value of each Employee Partnership is based on (i) the estimated value (as determined using a Black-Scholes option pricing model) of such Employee Partnership's assets that would be distributed to the Class B limited partners thereof upon liquidation and (ii) the value, based on a discounted cash flow analysis, of the residual quarterly cash amounts that such Class B limited partners are expected to receive over the life of the Employee Partnership.
The following table summarizes the assumptions we used in applying a Black-Scholes option pricing model to derive that portion of the estimated grant date fair value of the profits interest awards for each Employee Partnership:

| Expected | Risk-Free | Expected | Expected Unit
Employee | Life | Interest | Distribution | Price
Partnership | of Award | Rate | Yield | Volatility
EPD PubCo I | 4.0 years | 1.09% | 6.68% | 40%
EPD PubCo II | 5.0 years | 1.25% | 6.68% | 40%
EPD PrivCo I | 5.0 years | 1.25% | 6.68% | 40%

Compensation expense attributable to the profits interest awards is based on the estimated grant date fair value of each award. A portion of the fair value of these equity-based awards is allocated to us under the ASA as a non-cash expense. We are not responsible for reimbursing EPCO for any expenses of the Employee Partnerships, including the value of any contributions of units made by EPCO Holdings.
Note 12. Derivative Instruments, Hedging Activities and Fair Value Measurements
In the normal course of our business operations, we are exposed to certain risks, including changes in interest rates and commodity prices. In order to manage risks associated with assets, liabilities and certain anticipated future transactions, we use derivative instruments such as futures, forward contracts, swaps, options and other instruments with similar characteristics. Substantially all of our derivatives are used for non-trading activities.

Interest Rate Hedging Activities
We may utilize interest rate swaps, forward starting swaps and similar derivative instruments to manage our exposure to changes in interest rates charged on borrowings under certain consolidated debt agreements. This strategy may be used in controlling our overall cost of capital associated with such borrowings. The following table summarizes our portfolio of interest rate swaps at March 31, 2016:

Hedged Transaction | Number and Type of Derivatives Outstanding |  | Notional Amount |  | Period of Hedge | Rate Swap | Accounting Treatment
Senior Notes OO | 10 fixed-to-floating swaps |  | $ | 750.0 |  | 5/2015 to 5/2018 | 1.65% to 1.10% | Fair value hedge

Commodity Hedging Activities
The prices of natural gas, NGLs, crude oil, petrochemicals and refined products are subject to fluctuations in response to changes in supply and demand, market conditions and a variety of additional factors that are beyond our control. In order to manage such price risks, we enter into commodity derivative instruments such as physical forward contracts, futures contracts, fixed-for-float swaps, basis swaps and option contracts. The following table summarizes our portfolio of commodity derivative instruments outstanding at March 31, 2016 (volume measures as noted):

| Volume (1) | Accounting

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
At March 31, 2016, 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 forward contracts and derivative instruments.

§ | The objective of our natural gas processing hedging program is to hedge an amount of gross margin associated with these activities. We achieve this objective by executing forward fixed-price sales of a portion of our expected equity NGL production using forward contracts and commodity derivative instruments. 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 by executing forward fixed-price purchases using forward contracts and derivative instruments.

§ | 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 forward contracts and derivative instruments.

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

The following table provides quantitative information regarding our recurring Level 3 fair value measurements for commodity derivatives at March 31, 2016:

|  | Fair Value |  |  |  |

Commodity derivatives – Crude oil |  | $ | 1.6 |  |  | $ | 1.4 |  | Discounted cash flow | Forward commodity prices | $36.30-$43.03/barrel
Commodity derivatives – Propane |  |  | -- |  |  |  | 0.3 |  | Discounted cash flow | Forward commodity prices | $0.91-$0.93/gallon

Total |  | $ | 2.3 |  |  | $ | 1.7 |  |  |  |

With respect to commodity derivatives, we believe forward commodity prices are the most significant unobservable inputs in determining our Level 3 recurring fair value measurements at March 31, 2016. 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.

Other Fair Value Information
The carrying amounts of cash and cash equivalents (including restricted cash balances), accounts receivable, commercial paper notes and accounts payable approximate their fair values based on their short-term nature. The estimated total fair value of our fixed-rate debt obligations was $20.27 billion and $19.51 billion at March 31, 2016 and December 31, 2015, respectively. The aggregate carrying value of these debt obligations was $20.12 billion and $20.87 billion at March 31, 2016 and December 31, 2015, respectively. These values are based on quoted market prices for such debt or debt of similar terms and maturities (Level 2), our credit standing and the credit standing of our counterparties. Changes in market rates of interest affect the fair value of our fixed-rate debt. The amounts reported for fixed-rate debt obligations exclude those amounts hedged using fixed-to-floating interest rate swaps. See "Interest Rate Hedging Activities" within this Note 12 for additional information. The carrying values of our variable-rate long-term debt obligations approximate their fair values since the associated interest rates are market-based. We do not have any long-term investments in debt or equity securities recorded at fair value.

Relationship with EPCO and Affiliates
We have an extensive and ongoing relationship with EPCO and its privately held affiliates (including Enterprise GP, our general partner), which are not a part of our consolidated group of companies.
At March 31, 2016, EPCO and its privately held affiliates (including Dan Duncan LLC and certain Duncan family trusts) beneficially owned the following limited partner interests in us:

Total Number of Units | Percentage of Total Units Outstanding
685,481,428 | 33.3%

Of the total number of units held by EPCO and its privately held affiliates, 118,000,000 have been pledged as security under the credit facilities of certain of the privately held affiliates at March 31, 2016. These credit facilities contain customary and other events of default, including defaults by us and other affiliates of EPCO. An event of default, followed by a foreclosure on the pledged collateral, could ultimately result in a change in ownership of these units and affect the market price of our common units.
We and Enterprise GP are both separate legal entities apart from each other and apart from EPCO and its other affiliates, with assets and liabilities that are also separate from those of EPCO and its other affiliates. EPCO and its privately held affiliates depend on the cash distributions they receive from us and other investments to fund their other activities and to meet their debt obligations. During the three months ended March 31, 2016 and 2015, we paid EPCO and its privately held affiliates cash distributions totaling $260.1 million and $231.2 million, respectively. Distributions paid during 2015 excluded 35,380,000 Designated Units (see Note 8).
In January 2016, privately held affiliates of EPCO purchased 3,830,256 common units from us under our ATM program, generating gross proceeds of $100 million. In February 2016, privately held affiliates of EPCO reinvested $100 million through our DRIP, resulting in the issuance of an additional 4,481,504 of our common units. See Note 8 for additional information regarding our ATM program and DRIP.
We have no employees. All of our operating functions and general and administrative support services are provided by employees of EPCO pursuant to the ASA or by other service providers. The following table presents our related party costs and expenses attributable to the ASA with EPCO for the periods indicated:

|  | For the Three Months Ended March 31, |
|  | 2016 |  |  | 2015 |
Operating costs and expenses |  | $ | 205.4 |  |  | $ | 191.0 |
General and administrative expenses |  |  | 27.3 |  |  |  | 26.6 |
Total costs and expenses |  | $ | 232.7 |  |  | $ | 217.6 |

Note 14. 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.
35

Table of Contents
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 March 31, 2016 and December 31, 2015, our accruals for litigation contingencies were $2.6 million and $4.6 million, respectively, and were recorded in our Unaudited Condensed Consolidated Balance Sheets as a component of "Other current liabilities." Our evaluation of litigation contingencies is based on the facts and circumstances of each case and predicting the outcome of these matters involves uncertainties. In the event the assumptions we use to evaluate these matters change in future periods or new information becomes available, we may be required to record additional accruals. In an effort to mitigate expenses associated with litigation, we may settle legal proceedings out of court.
ETP Matter
In connection with a proposed pipeline project, we and Energy Transfer Partners, L.P. ("ETP") signed a non-binding letter of intent in April 2011 that disclaimed any partnership or joint venture related to such project absent executed definitive documents and board approvals of the respective companies. Definitive agreements were never executed and board approval was never obtained for the potential pipeline project. In August 2011, the proposed pipeline project was cancelled due to a lack of customer support.
In September 2011, ETP filed suit against us and a third party in connection with the cancelled project alleging, among other things, that we and ETP had formed a "partnership." The case was tried in the District Court of Dallas County, Texas, 298th Judicial District. While we firmly believe, and argued during our defense, that no agreement was ever executed forming a legal joint venture or partnership between the parties, the jury found that the actions of the two companies, nevertheless, constituted a legal partnership. As a result, the jury found that ETP was wrongfully excluded from a subsequent pipeline project involving a third party, and awarded ETP $319.4 million in actual damages on March 4, 2014. On July 29, 2014, the court entered judgment against us in an aggregate amount of $535.8 million, which includes (i) $319.4 million as the amount of actual damages awarded by the jury, (ii) an additional $150.0 million in disgorgement for the alleged benefit we received due to a breach of fiduciary duties by us against ETP and (iii) prejudgment interest in the amount of $66.4 million. The court also awarded post-judgment interest on such aggregate amount, to accrue at a rate of 5%, compounded annually.
We do not believe that the verdict or the judgment entered against us is supported by the evidence or the law. 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 has now been submitted to the Court of Appeals for its consideration. We intend to vigorously oppose the judgment through the appeals process. As of March 31, 2016, we have not recorded a provision for this matter as management believes payment of damages in this case is not probable.
FTC Inquiry regarding Oiltanking Acquisition
On February 23, 2015, we received a Civil Investigative Demand and a related Subpoena Duces Tecum from the FTC requesting specified information relating to the Oiltanking acquisition and our operations. On April 13, 2015, we received a Civil Investigative Demand issued by the Attorney General of the State of Texas requesting copies of the same information and any correspondence with the FTC. We are in the process of complying with the requests and are cooperating with the investigations. Based on the limited information that we have at this time, we are unable to predict the outcome of the investigations.
Contractual Obligations
Scheduled Maturities of Debt
We have long-term and short-term payment obligations under debt agreements. See Note 7 for additional information regarding our scheduled future maturities of debt principal.

Operating Lease Obligations
Consolidated lease and rental expense was $28.5 million and $22.4 million during the three months ended March 31, 2016 and 2015, respectively. Our operating lease commitments at March 31, 2016 did not differ materially from those reported in our 2015 Form 10-K.
Purchase Obligations
Our consolidated purchase obligations at March 31, 2016 did not differ materially from those reported in our 2015 Form 10-K.
Liquidity Option Agreement
We entered into a put option agreement (the "Liquidity Option Agreement") with OTA and Marquard & Bahls ("M&B") in connection with the Oiltanking acquisition. 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. At that time, OTA's only significant asset is expected to be the Enterprise common units it received in Step 1 of the Oiltanking acquisition, to the extent that such common units are not sold by M&B prior to the option exercise date pursuant to a related registration rights agreement.
If the Liquidity Option is exercised, we would indirectly acquire any Enterprise common units owned by OTA and assume all future income tax obligations of OTA associated with (i) owning common units encumbered by the entity-level taxes of a U.S. corporation and (ii) OTA's tax liabilities resulting from differences in the book and tax basis of such common units at the time of exercise.
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 $242.9 million and $245.1 million at March 31, 2016 and December 31, 2015, respectively. Results for the three months ended March 31, 2016 reflect a $2.2 million benefit, which is a component of "Other, net" on our Unaudited Condensed Consolidated Statements of Operations, attributable to the Liquidity Option Agreement.

Such amounts are not included under the caption "Capital expenditures" on the Unaudited Condensed Statements of Consolidated Cash Flows.
On certain of our capital projects, third parties are obligated to reimburse us for all or a portion of project expenditures. The majority of such arrangements are associated with projects related to pipeline construction activities and production well tie-ins.

Cautionary Statement Regarding Forward-Looking Information
This quarterly report on Form 10-Q contains various forward-looking statements and information that are based on our beliefs and those of our general partner, as well as assumptions made by us and information currently available to us.

Although we and our general partner believe that our expectations reflected in such forward-looking statements are reasonable, neither we nor our general partner can give any assurances that such expectations will prove to be correct. Forward-looking statements are subject to a variety of risks, uncertainties and assumptions as described in more detail under "Risk Factors" within Part I, Item 1A included in our 2015 Form 10-K and within Part II, Item 1A of this quarterly report. If one or more of these risks or uncertainties materialize, or if underlying assumptions prove incorrect, our actual results may vary materially from those anticipated, estimated, projected or expected. You should not put undue reliance on any forward-looking statements. The forward-looking statements in this quarterly report speak only as of the filing date hereof. Except as required by federal and state securities laws, we undertake no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or any other reason.
Overview of Business
We are a publicly traded Delaware limited partnership, the common units of which are listed on the New York Stock Exchange ("NYSE") under the ticker symbol "EPD." We were formed in April 1998 to own and operate certain natural gas liquid ("NGL") 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 midstream energy operations currently include: natural gas gathering, treating, processing, transportation and storage; NGL transportation, fractionation, storage, and import and export terminals (including liquefied petroleum gas or "LPG"); crude oil gathering, transportation, storage and terminals; petrochemical and refined products transportation, storage and terminals, and related services; and a marine transportation business that operates primarily on the U.S. inland and Intracoastal Waterway systems. Our assets currently include approximately 49,000 miles of pipelines; 250 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. 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 ("ASA") or by other service providers.
Our historical operations are reported under five business segments: (i) NGL Pipelines & Services, (ii) Crude Oil Pipelines & Services, (iii) Natural Gas Pipelines & Services, (iv) Petrochemical & Refined Products Services and (v) Offshore Pipelines & Services. On July 24, 2015, we completed the sale of our Offshore Business, which primarily consisted of our Offshore Pipelines & Services segment. Our consolidated financial statements reflect ownership of the Offshore Business through July 24, 2015. See Note 9 of the Notes to Unaudited Condensed Consolidated Financial Statements for additional information regarding our business segments.
As a result of our acquisition of the member interests of EFS Midstream effective July 1, 2015, we began consolidating the financial statements of EFS Midstream as of that date.
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
Start-Up of South Eddy Natural Gas Processing Plant in May 2016
In May 2016, we announced that our new cryogenic natural gas processing plant located in Eddy County, New Mexico (the "South Eddy" plant) had been placed into service. We constructed the South Eddy plant to serve producers in the Delaware Basin region. The South Eddy plant has a nameplate natural gas processing capacity of 200 MMcf/d and is capable of extracting up to 25 MBPD of NGLs. We also completed construction of approximately 90 miles of natural gas gathering pipelines to supply the new plant.
In addition to the South Eddy plant and its related natural gas gathering infrastructure, we also completed a 71-mile extension of our Mid-America Pipeline System. This extension provides producers in the Delaware Basin with NGL takeaway capacity and direct access to our integrated network of NGL assets.
Issuance of Common Units under our ATM Program and DRIP
For the period January 1, 2016 through April 8, 2016, we sold 60,947,078 common units under our "at-the-market" ("ATM") program for aggregate gross proceeds of $1.45 billion. This includes 3,830,256 common units sold in January 2016 to privately held affiliates of EPCO, which generated gross proceeds of $100 million. After taking into account applicable costs, our transactions under the ATM program during this period resulted in aggregate net cash proceeds of $1.44 billion.
In addition, we issued a total of 7,162,744 common units under our distribution reinvestment plan ("DRIP") during the three months ended March 31, 2016, which generated net cash proceeds of $159.8 million. This includes $100 million reinvested under the DRIP by privately held affiliates of EPCO in February 2016.
We used the proceeds from these sales for the repayment of debt and general company purposes.
Issuance of $1.25 Billion of Senior Notes
In April 2016, EPO issued $575 million in principal amount of 2.85% senior notes due April 2021 ("Senior Notes RR"), $575 million in principal amount of 3.95% senior notes due February 2027 ("Senior Notes SS") and $100 million in principal amount of 4.90% reopened senior notes due May 2046 ("Senior Notes QQ"). Senior Notes RR, SS and QQ were issued at 99.898%, 99.760% and 95.516% of their principal amounts, respectively. Net proceeds from the issuance of these senior notes were used as follows: (i) the repayment of amounts then outstanding under EPO's commercial paper program, which included amounts we used to repay $750 million in principal amount of Senior Notes AA that matured in February 2016, and (ii) for general company purposes.
Enterprise Management to Recommend 5.2% Distribution Growth for 2016
In January 2016, our management announced plans to recommend to the Board of Enterprise GP cash distributions totaling $1.61 per unit with respect to 2016, which, if approved by the Board, would represent a 5.2% increase compared to a total of $1.53 per unit of cash distributions declared with respect to calendar year 2015. In April 2016, our management recommended, and the Board of Enterprise GP declared, cash distributions of $0.395 per unit with respect to the first quarter of 2016. Historically, it has been our practice to not provide guidance with respect to distribution growth; however, due to actions by some of our midstream peers to reduce or freeze their dividends/distributions, we believed it was important to provide our investors with visibility into management's expected recommendations for our distribution growth in 2016 based on our view of future business conditions at the time of announcement.

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. Crude oil, natural gas and NGL prices have been depressed since the fourth quarter of 2014 primarily due to an oversupply of these commodities on world markets. The weighted-average indicative market price for NGLs was $0.40 per gallon in the first quarter of 2016 versus $0.54 per gallon during the first quarter of 2015.
A decrease in our consolidated marketing revenues due to lower energy commodity sales prices may not result in a decrease in gross operating margin or cash available for distribution, since our consolidated cost of sales amounts would also be lower due to comparable decreases in the purchase prices of the underlying energy commodities. The same correlation would be true in the case of higher energy commodity sales prices and purchase costs.
We attempt to mitigate any commodity price exposure through our hedging activities as well as through converting keepwhole and similar contracts to fee-based arrangements. See Note 12 of the Notes to Unaudited Condensed Consolidated Financial Statements included under Part I, Item 1 of this quarterly report for information regarding our commodity hedging activities.

Consolidated Income Statement Highlights
The following information highlights significant changes in our comparative income statement amounts and the primary drivers of such changes.
Revenues
Total revenues for the first quarter of 2016 decreased $2.47 billion when compared to total revenues for the first quarter of 2015. Revenues from the marketing of crude oil, natural gas and refined products decreased $1.95 billion quarter-to-quarter primarily due to lower sales prices and volumes, which accounted for a $1.68 billion decrease and a $275.0 million decrease, respectively. Revenues from the marketing of NGLs and petrochemicals decreased a net $517.3 million quarter-to-quarter primarily due to lower sales prices, which accounted for a $958.6 million decrease, partially offset by a $441.3 million increase due to higher sales volumes. Revenues from midstream services increased a net $41.3 million quarter-to-quarter primarily due to contributions from recently acquired assets, which were partially offset by a decrease due to the sale of our Offshore Business. Revenues for the first quarter of 2016 include $65.0 million from the assets we acquired effective July 1, 2015 in connection with the EFS Midstream acquisition. Revenues from midstream services decreased $34.4 million quarter-to-quarter due to the sale of our Offshore Business effective July 24, 2015.
Operating costs and expenses
Total operating costs and expenses for the first quarter of 2016 decreased $2.47 billion when compared to total operating costs and expenses for the first quarter of 2015. The cost of sales associated with our marketing of crude oil, natural gas and refined products decreased $1.8 billion quarter-to-quarter primarily due to lower purchase prices, which accounted for a $1.53 billion decrease, and lower sales volumes, which accounted for an additional $268.3 million decrease. The cost of sales associated with our marketing of NGLs and petrochemicals decreased a net $662.1 million quarter-to-quarter primarily due to lower purchase prices, which accounted for a $978.4 million decrease, partially offset by a $316.3 million increase due to higher sales volumes.
Other operating costs and expenses increased a net $14.0 million quarter-to-quarter. The inclusion of assets attributable to the EFS Midstream acquisition accounted for an $11.9 million increase. Other operating costs and expenses also decreased $8.9 million quarter-to-quarter due to the sale of our Offshore Business.
Depreciation, amortization and accretion expense in operating costs and expenses for the first quarter of 2016 increased a net $12.9 million when compared to the first quarter of 2015 primarily due to a $35.9 million increase attributable to assets we constructed and placed into service or acquired since the first quarter of 2015, partially offset by a $23.0 million quarter-to-quarter decrease attributable to the sale of our Offshore Business.
Operating costs and expenses also include $1.7 million and $33.3 million of non-cash asset impairment charges for the first quarters of 2016 and 2015, respectively. Our non-cash asset impairment charges for the first quarter of 2015 primarily relate to crude oil and natural gas pipeline assets in Texas.
General and administrative costs
General and administrative costs for the first quarter of 2016 decreased $5.4 million when compared to the first quarter of 2015 primarily due to lower costs for professional services.
Equity in income of unconsolidated affiliates
Equity income from our unconsolidated affiliates for the first quarter of 2016 increased a net $11.9 million when compared to the same period in 2015 primarily due to a $32.7 million increase in earnings from our investments in crude oil and NGL pipelines, partially offset by a $20.2 million reduction in equity earnings attributable to the sale of our Offshore Business.

Interest expense
Interest expense for the first quarter of 2016 increased $1.5 million when compared to the same period in 2015. The following table presents the components of our consolidated interest expense for the periods indicated (dollars in millions):

|  | For the Three Months Ended March 31, |
|  | 2016 |  |  | 2015 |
Interest charged on debt principal outstanding |  | $ | 268.3 |  |  | $ | 257.1 |
Impact of interest rate hedging program, including related amortization |  |  | 6.4 |  |  |  | 4.7 |
Interest costs capitalized in connection with construction projects (1) |  |  | (42.5 | ) |  |  | (29.6 | )
Other (2) |  |  | 8.4 |  |  |  | 6.9 |
Total |  | $ | 240.6 |  |  | $ | 239.1 |
(1) 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) ratably 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. (2) Primarily reflects facility commitment fees charged in connection with our revolving credit facilities and amortization of debt issuance costs. |

Interest charged on debt principal outstanding, which is the primary driver of interest expense, increased a net $11.2 million quarter-to-quarter primarily due to increased debt principal amounts outstanding during the first quarter of 2016, which accounted for a $14.2 million increase, partially offset by the effect of lower overall interest rates in the first quarter of 2016, which accounted for a $3.0 million decrease. Our weighted-average debt principal balance for the first quarter of 2016 was $22.96 billion compared to $21.67 billion for the first quarter of 2015. In general, our debt principal balances have increased over time due to the partial debt financing of our capital spending program. For a discussion of our consolidated debt obligations and capital spending program, see "Liquidity and Capital Resources" within this Part I, Item 2.

Natural gas processing and related NGL marketing activities. Gross operating margin from natural gas processing and related NGL marketing activities for the first quarter of 2016 decreased $6.3 million when compared to the first quarter of 2015. Gross operating margin from our natural gas processing plants decreased $43.5 million quarter-to-quarter primarily due to lower processing margins. Gross operating margin from our NGL marketing activities for the first quarter of 2016 increased a net $37.2 million when compared to the first quarter of 2015 primarily due to higher sales volumes, which accounted for a $75.0 million increase, partially offset by a $37.8 million decrease due to lower sales margins. NGL marketing sales volumes were higher during the first quarter of 2016 when compared to the first quarter of 2015 primarily due to expansion projects we completed during 2015 at our Houston Ship Channel marine terminal.
NGL pipelines, storage and terminals. Gross operating margin from NGL pipelines, storage and terminal assets for the first quarter of 2016 increased $98.5 million when compared to the first quarter of 2015. Gross operating margin from our Houston Ship Channel marine terminal and related pipeline increased $34.2 million quarter-to-quarter primarily due to higher marine terminal and pipeline transportation volumes of 196 MBPD and 164 MBPD, respectively. In April 2015, we completed an expansion project at our Houston Ship Channel marine terminal that increased our ability to load cargos of LPGs from 7.5 MMBbls per month to approximately 9.0 MMBbls per month. In December 2015, we completed a second expansion project at the terminal further increasing our ability to load cargos of LPGs to approximately 16.0 MMBbls per month.
Gross operating margin from our ATEX and Aegis Ethane Pipelines increased a combined $28.6 million quarter-to-quarter primarily due to a combined 148 MBPD increase in transportation volumes. The second segment of our Aegis Ethane Pipeline was placed into service in September 2015. The third and final segment of our Aegis Ethane Pipeline was placed into service in December 2015.
Gross operating margin from the Mid-America Pipeline System, Seminole Pipeline and related terminals increased $13.2 million quarter-to-quarter primarily due to higher transportation volumes of 86 MBPD. NGL volumes transported on these pipelines for delivery to Mont Belvieu, Texas were higher during the first quarter of 2016 when compared to the first quarter of 2015 primarily due to commodity price differences between Conway, Kansas and Mont Belvieu. Gross operating margin from our South Texas NGL Pipeline System increased $6.3 million quarter-to-quarter attributable to a 36 MBPD increase in transportation volumes. The South Texas NGL Pipeline System benefited from a quarter-to-quarter increase in production from the Eagle Ford Shale region and an increase in mixed NGLs received from our Seminole Pipeline for delivery to our storage and fractionation complex in Mont Belvieu, Texas.

Table of Contents
Gross operating margin from our Tri-States NGL Pipeline increased $4.7 million quarter-to-quarter due to a $2.1 million increase from higher transportation volumes of 7 MBPD (net to our interest), higher tariffs, which accounted for a $2.0 million increase, and a $0.6 million decrease in operating expenses. Lastly, gross operating margin from our investments in the Front Range Pipeline, Texas Express Pipeline and Texas Express Gathering System for the first quarter of 2016 increased $3.7 million primarily due to a combined 17 MBPD increase in transportation volumes (net to our interest) when compared to the first quarter of 2015.
NGL fractionation. Gross operating margin from NGL fractionation for the first quarter of 2016 decreased $3.7 million when compared to the first quarter of 2015. Gross operating margin from our Mont Belvieu NGL fractionators decreased a net $6.1 million quarter-to-quarter primarily due to a combined $10.2 million decrease in product blending and other fee revenues, partially offset by a $4.5 million increase due to higher fractionation volumes of 11 MBPD (net to our interest). Certain of the product blending and other fee revenues are influenced by energy commodity prices, which have generally declined since the beginning of 2014.
Crude Oil Pipelines & Services
The following table presents segment gross operating margin and selected volumetric data for the Crude Oil Pipelines & Services segment for the periods indicated (dollars in millions, volumes as noted):

|  | For the Three Months Ended March 31, |
|  | 2016 |  |  | 2015 |
Segment gross operating margin |  | $ | 202.3 |  |  | $ | 214.0 |
Selected volumetric data: |  |  |  |  |  |  |  |

Crude oil marine terminal volumes (MBPD) |  |  | 479 |  |  |  | 644 |

Gross operating margin from our Crude Oil Pipelines & Services segment for the first quarter of 2016 decreased $11.7 million when compared to the first quarter of 2015. Gross operating margin from our crude oil marketing and related trucking activities decreased $70.5 million quarter-to-quarter primarily due to lower crude oil sales margins, which includes the impact of approximately $13.3 million of non-cash mark-to-market losses in the first quarter of 2016 on financial instruments related to blending activities. As a result of lower crude oil prices, regional price spreads were less than the costs incurred by our marketing business, such as transportation costs on the Seaway Pipeline. Our crude oil marketing business has contracted for 75 MBPD of firm capacity on the Seaway Pipeline of which 25 MBPD of capacity terminates June 1, 2017 and the remaining 50 MBPD terminates February 1, 2018. Sales margins on Seaway Pipeline-related capacity were $31.1 million lower in the first quarter of 2016 compared to the first quarter of 2015.
Gross operating margin from our South Texas Crude Oil Pipeline System decreased $23.8 million quarter-to-quarter primarily due to a 76 MBPD decrease in volumes, which accounted for a $17.9 million decrease, and a $4.0 million decrease due to lower average transportation fees. The decrease in crude oil transportation volumes was primarily due to lower Eagle Ford Shale production attributable to reduced drilling activity.
The EFS Midstream system, which we acquired effective July 1, 2015, contributed $53.3 million of gross operating margin and 63 MBPD of throughput volumes for the first quarter of 2016. Gross operating margin from crude oil terminaling services at our Houston Ship Channel, Beaumont Marine West and Enterprise Crude Houston ("ECHO") facilities increased a combined $19.5 million quarter-to-quarter primarily due to expansion projects (e.g., the construction of new storage tanks) we completed at these facilities since the first quarter of 2015. Our crude oil marine terminal volumes decreased 165 MBPD quarter-to-quarter primarily due to lower crude oil volumes unloaded from marine vessels (i.e., crude oil imports) at our Houston Ship Channel and Beaumont Marine West facilities.

Gross operating margin from our equity investment in the Seaway Pipeline increased $11.0 million quarter-to-quarter. In February 2016, the Federal Energy Regulatory Commission ("FERC") issued its decision regarding the various challenges to Seaway's committed and uncommitted rates in FERC Docket No. IS12-226-000. The FERC upheld the committed rates and rejected the claim that the committed rates should be reduced to cost-based levels. The FERC's rulings regarding the uncommitted rates were also largely favorable to Seaway. Seaway submitted a compliance filing on March 17, 2016 calculating revised uncommitted rates consistent with the FERC's order. The compliance filing was not challenged. As a result of the FERC ruling, Seaway recognized $22.2 million of revenues (on a 100% basis) in the first quarter of 2016 that had previously been deferred.
Natural Gas Pipelines & Services
The following table presents segment gross operating margin and selected volumetric data for the Natural Gas Pipelines & Services segment for the periods indicated (dollars in millions, volumes as noted):

Gross operating margin from our Natural Gas Pipelines & Services segment for the first quarter of 2016 decreased $26.8 million when compared to the first quarter of 2015. Gross operating margin from our Texas Intrastate System decreased $9.4 million quarter-to-quarter primarily due to lower firm capacity reservation revenues attributable to decreased producer activity in the Eagle Ford Shale. Gross operating margin from our Acadian Gas and Piceance Basin Systems decreased a combined $7.1 million quarter-to-quarter primarily due to reduced transportation fees. Gross operating margin from our San Juan Gathering System decreased $5.5 million quarter-to-quarter primarily due to lower gathering volumes of 98 BBtus/d, which accounted for a $2.2 million decrease, and a $1.8 million decrease in gathering fee revenues. Gathering fees on the San Juan Gathering System, which are indexed to regional natural gas prices, decreased quarter-to-quarter due to lower natural gas prices in the first quarter of 2016 when compared to the first quarter of 2015.

Butane isomerization and deisobutanizer operations. Gross operating margin from butane isomerization and deisobutanizer ("DIB") operations for the first quarter of 2016 increased $9.2 million when compared to the first quarter of 2015. This increase is primarily due to higher butane isomerization and standalone DIB processing volumes of 48 MBPD and 31 MBPD, respectively.
Octane enhancement and HPIB plant operations. Gross operating margin from our octane enhancement facility and high purity isobutylene ("HPIB") plant for the first quarter of 2016 decreased $11.3 million when compared to the first quarter of 2015. This decrease is primarily due to lower sales volumes, which accounted for a $6.7 million decrease, lower sales margins, which accounted for an additional $1.5 million decrease, and a $2.6 million quarter-to-quarter increase in operating expenses. Our octane enhancement facility was out of service for extended periods during the first quarters of 2016 and 2015 for major maintenance activities.
Refined products pipelines and related activities. Gross operating margin from refined products pipelines and related marketing activities for the first quarter of 2016 increased $0.7 million when compared to the first quarter of 2015. Gross operating margin from refined products terminaling services at our facilities in Beaumont, Texas increased a net $5.2 million quarter-to-quarter due to a $9.1 million increase in revenues, the primary driver of which was an 18 MBPD increase in marine terminal volumes, partially offset by a $3.9 million increase in operating expenses. Gross operating margin from our refined products marketing activities decreased $4.3 million quarter-to-quarter primarily due to lower sales margins, which includes a $1.2 million decrease attributable to non-cash mark-to-market losses.
Gross operating margin for the TE Products Pipeline and related terminals increased $0.9 million quarter-to-quarter. Interstate pipeline transportation volumes on our TE Products Pipeline increased a net 16 MBPD quarter-to-quarter primarily due to a 26 MBPD increase in refined products transportation volumes, which was partially offset by a 10 MBPD decrease in NGL transportation volumes resulting from warmer weather and reduced terminal demand in the Northeast U.S. Intrastate refined products and petrochemical pipeline transportation volumes on our TE Products Pipeline increased a combined 69 MBPD quarter-to-quarter.
Other. Gross operating margin from these activities decreased $6.1 million quarter-to-quarter primarily due to lower demand for marine transportation services attributable to the lower commodity pricing environment.
Offshore Pipelines & Services
We sold our Offshore Business to Genesis on July 24, 2015. The following table presents segment gross operating margin and selected volumetric data for the Offshore Pipelines & Services segment for three months ended March 31, 2015 (dollars in millions, volumes as noted):

Liquidity and Capital Resources
Based on current market conditions (as of the filing date of this quarterly report), we believe we will have sufficient liquidity, cash flow from operations and access to capital markets to fund our capital expenditures and working capital needs for the reasonably foreseeable future. At March 31, 2016, we had $3.6 billion of consolidated liquidity, which was comprised of $3.43 billion of available borrowing capacity under EPO's revolving credit facilities and $160.6 million of unrestricted cash on hand.
We expect to issue additional equity and debt securities to assist us in meeting our future liquidity requirements, including those related to capital spending. We have a universal shelf registration statement (the "2013 Shelf") on file with the SEC. The 2013 Shelf allows Enterprise Products Partners L.P. and EPO (each on a standalone basis) to issue an unlimited amount of equity and debt securities, respectively. The 2013 Shelf will expire in June 2016, at which time we expect to file a replacement universal shelf registration statement.

As discussed under "Significant Recent Developments" within this Item 2, we sold 60,947,078 common units under our ATM program, which generated aggregate gross proceeds of $1.45 billion, from January 1, 2016 through April 8, 2016. Pursuant to this program, we may sell common units under an equity distribution agreement between Enterprise Products Partners L.P. and certain broker-dealers from time-to-time by means of ordinary brokers' transactions through the NYSE at market prices, in block transactions or as otherwise agreed to with the broker-dealer parties to the agreement. After taking into account the aggregate sales price of common units sold under our ATM program through April 8, 2016, our capacity under the applicable registration statement was reduced to $415.7 million. On April 22, 2016, we filed a registration statement with the SEC that (when declared effective) will replace our existing registration statement with respect to the ATM program and increase the available capacity under the ATM program to allow us to issue up to an aggregate $2.17 billion of additional common units, inclusive of the remaining capacity under such existing registration statement.

For additional information regarding our debt agreements, see Note 7 of the Notes to Unaudited Condensed Consolidated Financial Statements included under Part I, Item 1 of this quarterly report.
As discussed under "Significant Recent Developments" within this Item 2, we issued $1.25 billion of senior notes in April 2016. These notes were issued under the 2013 Shelf. Enterprise Products Partners L.P. has unconditionally guaranteed these senior notes on an unsecured and unsubordinated basis. These senior notes rank equal with EPO's existing and future unsecured and unsubordinated indebtedness and are senior to any existing and future subordinated indebtedness of EPO. These senior notes are subject to make-whole redemption rights and were issued under an indenture containing certain covenants, which generally restrict EPO's ability (with certain exceptions) to incur debt secured by liens and engage in sale and leaseback transactions.
Issuance of Common Units
The following table summarizes the issuance of common units in connection with our underwritten equity offerings, ATM program, distribution reinvestment plan ("DRIP") and employee unit purchase plan ("EUPP") for the period January 1, 2016 through April 8, 2016 (dollars in millions, number of units issued as shown):

|  | Number of Common Units Issued |  |  | Net Cash Proceeds Received |
Common units issued in connection with ATM program: |  |  |  |  |  |
January 1, 2016 through March 31, 2016 |  |  | 35,396,147 |  |  | $ | 849.0 |
April 1, 2016 through April 8, 2016 |  |  | 25,550,931 |  |  |  | 592.0 |
Common units issued in connection with DRIP and EUPP |  |  | 7,282,006 |  |  |  | 162.5 |
Total |  |  | 68,229,084 |  |  | $ | 1,603.5 |

Privately held affiliates of EPCO invested an aggregate $200 million in us through our ATM program and the DRIP during the three months ended March 31, 2016 (this amount being a component of the net cash proceeds presented in the preceding table).
After taking into account the number of common units issued under the DRIP through March 31, 2016, we have the capacity to issue an additional 7,905,254 common units under this plan. We expect to file a new registration statement during the second quarter of 2016 to increase the number of common units available for issuance under the DRIP.

Credit Ratings
As of April 30, 2016, the investment-grade credit ratings of EPO's long-term senior unsecured debt securities were BBB+ from Standard and Poor's and Baa1 from Moody's. In addition, the credit ratings of EPO's short-term senior unsecured debt securities were A-2 from Standard and Poor's and P-2 from Moody's. Fitch Ratings issued non-solicited ratings of BBB+ and F-2 for EPO's long-term senior unsecured debt securities and short-term senior unsecured debt securities, respectively.
EPO's credit ratings reflect only the view of a rating agency and should not be interpreted as a recommendation to buy, sell or hold any of our securities. A credit rating can be revised upward or downward or withdrawn at any time by a rating agency, if it determines that circumstances warrant such a change. A credit rating from one rating agency should be evaluated independently of credit ratings from other rating agencies.
Cash Flows from Operating, Investing and Financing Activities
The following table summarizes our consolidated cash flows from operating, investing and financing activities for the periods indicated (dollars in millions). For additional information regarding our cash flow amounts, please refer to the Unaudited Condensed Statements of Consolidated Cash Flows included under Part I, Item 1 of this quarterly report.

|  | For the Three Months Ended March 31, |
|  | 2016 |  |  | 2015 |
Net cash flows provided by operating activities |  | $ | 899.7 |  |  | $ | 954.0 |
Cash used in investing activities |  |  | 1,163.9 |  |  |  | 889.1 |
Cash provided by (used in) financing activities |  |  | 405.8 |  |  |  | (58.2 | )

Net cash flows provided by operating activities are largely dependent on earnings from our consolidated business activities. We operate in the midstream energy industry, which includes gathering, transporting, processing, fractionating and storing natural gas, NGLs, crude oil, petrochemicals and refined products. As such, changes in the prices of hydrocarbon products and in the relative price levels among hydrocarbon products could have a material adverse effect on our financial position, results of operations and cash flows. Changes in prices may impact demand for hydrocarbon products, which in turn may impact production, demand and the volumes of products for which we provide services. In addition, decreases in demand may be caused by other factors, including prevailing economic conditions, reduced demand by consumers for the end products made with hydrocarbon products, increased competition, adverse weather conditions and government regulations affecting prices and production levels. We may also incur credit and price risk to the extent counterparties do not fulfill their obligations to us in connection with our marketing of natural gas, NGLs, propylene, refined products and/or crude oil and long-term take-or-pay agreements. For a more complete discussion of these and other risk factors pertinent to our business, see "Risk Factors" under Part I, Item 1A of our 2015 Form 10-K and under Part II, Item 1A of this quarterly report.
Comparison of Three Months Ended March 31, 2016 with Three Months Ended March 31, 2015
The following information highlights significant quarter-to-quarter fluctuations in our consolidated cash flow amounts:
Operating Activities. Net cash flows provided by operating activities for the three months ended March 31, 2016 decreased $54.3 million when compared to the same period in 2015. The decrease in cash provided by operating activities was primarily due to:

§ | a $47.4 million quarter-to-quarter decrease in cash primarily due to the timing of cash receipts and payments related to operations; and

§ | a $27.7 million quarter-to-quarter decrease in cash distributions received from unconsolidated affiliates primarily due to the sale of our Offshore Business in July 2015; partially offset by

57

Table of Contents

§ | a $20.8 million increase in cash attributable to higher partnership income in the three months ended March 31, 2016 compared to the same period in 2015 (after adjusting our $19.6 million quarter-to-quarter increase in net income for changes in the non-cash items identified on our Unaudited Condensed Statements of Consolidated Cash Flows).

For information regarding significant quarter-to-quarter changes in our consolidated net income and underlying segment results, see "Results of Operations" within this Part I, Item 2.
Investing Activities. Cash used in investing activities for the three months ended March 31, 2016 increased $274.8 million when compared to the same period in 2015 primarily due to:

§ | a $201.8 million quarter-to-quarter increase in capital spending for consolidated property, plant and equipment, net of contributions in aid of construction costs; and

§ | a $92.8 million quarter-to-quarter increase in restricted cash requirements; partially offset by

§ | a $12.9 million quarter-to-quarter increase in proceeds from asset sales.

Financing Activities. Net cash provided by financing activities for the three months ended March 31, 2016 was $405.8 million compared to net cash used in financing activities of $58.2 million for the same period in 2015. The $464.0 million quarter-to-quarter change in cash flow from financing activities was primarily due to:

§ | a $543.1 million quarter-to-quarter increase in net cash proceeds from the issuance of common units. We issued an aggregate 42,678,153 common units in connection with our ATM program, DRIP and EUPP during the three months ended March 31, 2016, which generated $1.01 billion of net cash proceeds. This compares to an aggregate 14,291,593 common units we issued in connection with our ATM program, DRIP and EUPP during the same period in 2015, which collectively generated $468.4 million of net cash proceeds; partially offset by

§ | an $84.5 million quarter-to-quarter increase in cash distributions paid to limited partners during the three months ended March 31, 2016 when compared to the same period in 2015. The increase in cash distributions is due to increases in both the number of distribution-bearing common units outstanding and the quarterly cash distribution rates per unit; and

§ | a $26.1 million quarter-to-quarter decrease in net borrowings under our consolidated debt agreements. Net issuances under EPO's commercial paper program were $953.3 million during the three months ended March 31, 2016 compared $479.3 million during the same period in 2015. In addition, EPO repaid $750.0 million in principal amount of debt obligations during the three months ended March 31, 2016 compared to the repayment of $250.0 million in principal amount of senior notes during the same period in 2015.

Cash Distributions to Limited Partners
Our partnership agreement requires us to make quarterly distributions to our unitholders of all available cash, after any cash reserves established by Enterprise GP in its sole discretion. Cash reserves include those for the proper conduct of our business including, for example, those for capital expenditures, debt service, working capital, operating expenses, commitments and contingencies and other significant amounts. The retention of cash by the partnership allows us to reinvest in our growth and reduce our future reliance on the equity and debt capital markets.
Based on the level of available cash, management proposes a quarterly cash distribution rate to the Board of Enterprise GP, which has sole authority in approving such matters. Unlike most 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 IDRs or other equity interests. See "Significant Recent Developments" within this Item 2 for additional information regarding cash distributions with respect to 2016.

(6) At the sole discretion of Enterprise GP, cash retained by the partnership with respect to each of these periods was primarily reinvested in our growth capital spending program, which substantially reduced our reliance on the equity and debt capital markets to fund such major expenditures. (7) Distribution coverage ratio is determined by dividing distributable cash flow by total cash distributions paid to limited partners and in connection with distribution equivalent rights with respect to the period. |

For additional information regarding non-GAAP distributable cash flow, see "Other Items – Use of Non-GAAP Financial Measures" within this Part I, Item 2. Our use of distributable cash flow for the limited purposes described above and in this report is not a substitute for net cash flows provided by operating activities, the most comparable GAAP measure.

Designated Units Issued in Connection with Holdings Merger
In November 2010, we completed our merger with Enterprise GP Holdings L.P. (the "Holdings Merger"). In connection with the Holdings Merger, a privately held affiliate of EPCO agreed to temporarily waive the regular cash distributions it would otherwise receive from us with respect to a certain number of our common units it owns (the "Designated Units"). Distributions paid by us to this privately held affiliate of EPCO during 2015 excluded 35,380,000 Designated Units. The temporary distribution waiver expired at the end of calendar year 2015; therefore, distributions to be paid, if any, during calendar year 2016 will include all common units owned by the privately held affiliates of EPCO.
Capital Spending
An important part of our business strategy involves expansion through growth capital projects, business combinations and investments in joint ventures. We believe that we are positioned to continue to expand our network of assets through the construction of new facilities and to capitalize on expected increases in natural gas, NGL and crude oil production resulting from development activities in the Rocky Mountains, Mid-Continent, Northeast and U.S. Gulf Coast regions, including the Niobrara, Barnett, Eagle Ford, Permian, Haynesville, Marcellus and Utica Shale plays. Although our focus in recent years has been on expansion through growth capital projects, management continues to analyze potential business combinations, asset acquisitions, joint ventures and similar transactions with businesses that operate in complementary markets or geographic regions. In light of current business conditions, we expect that these opportunities will increase.
We completed approximately $300 million of growth capital projects in the first quarter of 2016 and are on schedule to complete and begin commercial service on another $2.2 billion of growth capital projects during the remainder of 2016. These projects include two natural gas processing plants and related infrastructure serving the Permian Basin (including our South Eddy facility which was commissioned in early May 2016); our ethane export terminal on the Houston Ship Channel; and additional crude oil storage infrastructure in the Houston and Beaumont areas. We have a total of $4.2 billion of growth projects scheduled to be completed in 2017 and 2018, with our two largest projects being the PDH facility and Midland-to-Sealy Pipeline.
We currently expect our total capital spending for the remainder of 2016 to approximate $3.1 billion, which includes the $1.0 billion final installment for EFS Midstream and approximately $215 million for sustaining capital expenditures. Our forecast of capital spending for the remainder of 2016 is based on our announced strategic operating and growth plans (through the filing date of this quarterly report), which are dependent upon our ability to generate the required funds from either operating cash flows or other means, including borrowings under debt agreements, the issuance of additional equity and debt securities, and potential divestitures. We may revise our forecast of capital spending due to factors beyond our control, such as adverse economic conditions, weather related issues and changes in supplier prices. Furthermore, our forecast of capital spending may change as a result of decisions made by management at a later date, which may include unforeseen acquisition opportunities.
Our success in raising capital, including the formation of joint ventures to share costs and risks, continues to be a significant factor in determining how much capital we can invest. We believe our access to capital resources is sufficient to meet the demands of our current and future growth needs and, although we expect to make the forecast capital expenditures noted above, we may adjust the timing and amounts of projected expenditures in response to changes in capital market conditions.

(1) Amount represents non-cash equity consideration we issued to complete Step 2 of the Oiltanking acquisition. (2) On certain of our capital projects, third parties are obligated to reimburse us for all or a portion of project expenditures. The majority of such arrangements are associated with pipeline construction projects and production well tie-ins. Contributions in aid of construction costs were $12.2 million and $19.6 million for the three months ended March 31, 2016 and 2015, respectively. Growth and sustaining capital amounts presented in the table above are presented net of related contributions in aid of construction costs. (3) Growth capital projects either (a) result in new sources of cash flow due to enhancements of or additions to existing assets (e.g., additional revenue streams, cost savings resulting from debottlenecking of a facility, etc.) or (b) expand our asset base through construction of new facilities that will generate additional revenue streams and cash flows. (4) Sustaining capital expenditures are capital expenditures (as defined by GAAP) resulting from improvements to existing assets. Such expenditures serve to maintain existing operations but do not generate additional revenues or result in significant cost savings. |

Fluctuations in our spending for growth capital projects and investments in unconsolidated affiliates are explained in large part by increases or decreases in spending on major expansion projects. Our most significant growth capital expenditures for the three months ended March 31, 2016 involved projects at our Mont Belvieu complex. Fluctuations in spending for sustaining capital projects are explained in large part by the timing and cost of pipeline integrity and similar projects.
Comparison of First Quarter of 2016 with First Quarter of 2015
In total, capital spending for property, plant and equipment increased $201.8 million quarter-to-quarter primarily due to higher growth capital spending during the three months ended March 31, 2016. Growth capital spending at our Mont Belvieu complex increased $91.5 million quarter-to-quarter primarily due to ongoing construction of our PDH facility. Currently, we expect construction of the PDH facility to be completed in the first quarter of 2017 with commercial operations expected to begin in the second quarter of 2017. Growth capital spending on our natural gas processing and related pipeline projects in the Delaware Basin increased a combined $50.8 million quarter-to-quarter. Our South Eddy natural gas processing plant and related pipeline infrastructure began operations in May 2016. Growth capital spending at our natural gas processing plants in South Louisiana increased $34.5 million quarter-to-quarter.
Growth capital spending on our Midland-to-Sealy and Rancho II pipelines increased a net $43.5 million quarter-to-quarter. With completion expected in mid-2018, the Midland-to-Sealy Pipeline will transport crude oil from Midland, Texas to our storage facility in Sealy, Texas. Volumes arriving in Sealy would then be transported to our ECHO terminal using our Rancho II pipeline. The Rancho II pipeline, a component of our South Texas Crude Oil Pipeline System, was completed and entered commercial service in September 2015. Lastly, growth capital spending for the expansion of crude oil terminal assets at our ECHO, Houston Ship Channel and Beaumont Marine West terminals increased a net $31.3 million quarter-to-quarter.
Growth capital spending at our Houston Ship Channel LPG and ethane export facilities decreased a combined $88.5 million quarter-to-quarter. We completed two expansion projects during 2015 at our Houston Ship Channel LPG export facility that increased our ability to load cargos of fully refrigerated, low-ethane propane to approximately 16.0 MMBbls per month. Work also continues at our Houston Ship Channel ethane export facility, which we expect to begin operations in the third quarter of 2016.

Critical Accounting Policies and Estimates
A discussion of our critical accounting policies and estimates is included in our 2015 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.

Use of Non-GAAP Financial Measures
Gross operating margin
We evaluate segment performance based on the non-GAAP financial measure of gross operating margin. Gross operating margin (either in total or by individual segment) is an important performance measure of the core profitability of our operations. This measure forms the basis of our internal financial reporting and is used by our executive management in deciding how to allocate capital resources among business segments. We believe that investors benefit from having access to the same financial measures that our management uses in evaluating segment results. The GAAP financial measure most directly comparable to total segment gross operating margin is operating income. For additional information regarding gross operating margin, see Note 9 of the Notes to Unaudited Condensed Consolidated Financial Statements under Part I, Item 1 of this quarterly report.
The following table presents a reconciliation of non-GAAP total segment gross operating margin to GAAP operating income for the periods indicated (dollars in millions):

Distributable cash flow
Our management compares the distributable cash flow we generate to the cash distributions we expect to pay our partners. Using this metric, management computes our distribution coverage ratio. Distributable cash flow is an important non-GAAP financial measure for our limited partners since it serves as an indicator of our success in providing a cash return on investment. Specifically, this financial measure indicates to investors whether or not we are generating cash flows at a level that can sustain or support an increase in our quarterly cash distributions. Distributable cash flow is also a quantitative standard used by the investment community with respect to publicly traded partnerships because the value of a partnership unit is, in part, measured by its yield, which is based on the amount of cash distributions a partnership can pay to a unitholder. The GAAP measure most directly comparable to distributable cash flow is net cash flows provided by operating activities.
The following table presents a reconciliation of non-GAAP distributable cash flow to GAAP net cash flows provided by operating activities for the periods indicated (dollars in millions):

|  | For the Three Months Ended March 31, |

Contractual Obligations
Our consolidated principal debt obligations at March 31, 2016 were approximately $22.95 billion compared to $22.74 billion at December 31, 2015. For information regarding the scheduled maturities of such debt, see "Liquidity and Capital Resources – Consolidated Debt" within this Part I, Item 2. See Note 7 of the Notes to Unaudited Condensed Consolidated Financial Statements under Part I, Item 1 of this quarterly report for additional information regarding our consolidated debt obligations.
Off-Balance Sheet Arrangements
We have no off-balance sheet arrangements that have or are reasonably expected to have a material current or future effect on our financial position, results of operations and cash flows.
Related Party Transactions
For information regarding our related party transactions, see Note 13 of the Notes to Unaudited Condensed Consolidated Financial Statements included under Part I, Item 1 of this quarterly report.
Item 3. Quantitative and Qualitative Disclosures About Market Risk.
General
In the normal course of our business operations, we are exposed to certain risks, including changes in interest rates and commodity prices. In order to manage risks associated with assets, liabilities and certain anticipated future transactions, we use derivative instruments such as futures, forward contracts, swaps, options and other instruments with similar characteristics. Substantially all of our derivatives are used for non-trading activities.
Our exposures to market risk have not changed materially since those reported under Part II, Item 7A, "Quantitative and Qualitative Disclosures About Market Risk," included in our 2015 Form 10-K.
63

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

Commodity Hedging Activities
The prices of natural gas, NGLs, crude oil, petrochemicals and refined products are subject to fluctuations in response to changes in supply and demand, market conditions and a variety of additional factors that are beyond our control. In order to manage such price risks, we enter into commodity derivative instruments such as physical forward contracts, futures contracts, fixed-for-float swaps, basis swaps and option contracts. The following table summarizes our portfolio of commodity derivative instruments outstanding at March 31, 2016 (volume measures as noted):

(1) Volume for derivatives designated as hedging instruments reflects the total amount of volumes hedged whereas volume for derivatives not designated as hedging instruments reflects the absolute value of derivative notional volumes. (2) The maximum term for derivatives designated as cash flow hedges, derivatives designated as fair value hedges and derivatives not designated as hedging instruments is December 2017, December 2016 and March 2019, respectively. (3) Forecasted sales of NGL volumes under natural gas processing exclude 0.3 MMBbls of additional hedges executed under contracts that have been designated as normal sales agreements. (4) Current and long-term volumes include 51.0 Bcf and 2.1 Bcf, respectively, of physical derivative instruments that are predominantly priced at a marked-based index plus a premium or minus a discount related to location differences. (5) Reflects the use of derivative instruments to manage risks associated with transportation, processing and storage assets.

At March 31, 2016, 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 forward contracts and derivative instruments.

§ | The objective of our natural gas processing hedging program is to hedge an amount of gross margin associated with these activities. We achieve this objective by executing forward fixed-price sales of a portion of our expected equity NGL production using forward contracts and commodity derivative instruments. 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 by executing forward fixed-price purchases using forward contracts and derivative instruments.

Interest Rate Hedging Activities
We may utilize interest rate swaps, forward starting swaps and similar derivative instruments to manage our exposure to changes in interest rates charged on borrowings under certain consolidated debt agreements. This strategy may be used in controlling our overall cost of capital associated with such borrowings. The composition of our derivative instrument portfolios may change depending on our hedging requirements.
With respect to the tabular data below, each portfolio's estimated fair value at a given date is based on a number of factors, including the number and types of derivatives outstanding at that date, the notional value of the swaps and associated interest rates.
Interest rate swaps exchange the stated interest rate paid on a notional amount of existing debt for the fixed or floating interest rate stipulated in the derivative instrument. The following table summarizes our portfolio of interest rate swaps at March 31, 2016 (dollars in millions):

Hedged Transaction | Number and Type of Derivatives Outstanding |  | Notional Amount |  | Period of Hedge | Rate Swap | Accounting Treatment
Senior Notes OO | 10 fixed-to-floating swaps |  | $ | 750.0 |  | 5/2015 to 5/2018 | 1.65% to 1.10% | Fair value hedge

Item 5. | Other Information.

Disclosure Under Section 13(r) of the Securities Exchange Act of 1934
Under Section 13(r) of the Securities Exchange Act of 1934, as amended by the Iran Threat Reduction and Syria Human Rights Act of 2012, issuers are required to include certain disclosures in their periodic reports if they or any of their "affiliates" (as defined in Rule 12b-2 thereunder) have knowingly engaged in certain specified activities relating to Iran. Disclosure is required even where the activities are conducted outside the U.S. by non-U.S. affiliates in compliance with applicable law, and even if the activities are not covered or prohibited by U.S. law.
Dr. F. Christian Flach was named a director of our general partner in October 2014 in connection with the acquisition of Oiltanking. Dr. Flach is also a managing director of Oiltanking GmbH, which maintains a joint venture interest in Oiltanking Odfjell GmbH, which in turn owns a joint venture interest in the Exir Chemical Terminal ("ECT") in Iran. This interest results from an investment dating back to 2002. Oiltanking GmbH currently has the contractual right to vote for the appointment of one member of ECT's three-member board. Oiltanking GmbH provides no goods, services, technology, information or support to ECT and plays no role in the management or day-to-day operations of ECT.
Among other activities, ECT provides transit storage for naphtha originating in Iraq en route to Oman for a customer in the United Arab Emirates. ECT does not import or handle any products originated from Iran that are regulated under U.S., European Union or United Nations sanctions laws. ECT pays routine and standard charges (i) to the Petrochemical Special Economic Zone Organization ("Petzone") for the use of pipelines and (ii) to Terminals and Tanks Petrochemical Co. ("TTPC"), which operates the berth. Petzone and TTPC are subsidiaries of the National Petrochemical Company, which is owned and controlled by the Government of Iran. As Oiltanking GmbH has no direct involvement in the day-to-day operations of ECT, we have no information regarding ECT's intent to continue or not continue making the payments described above.
Oiltanking GmbH maintains an internal compliance program to ensure compliance with all applicable sanctions regimes, including sanctions laws maintained by the U.S., European Union and United Nations. Although the existence of the routine payments described above may be reportable under Section 13(r), Oiltanking GmbH has informed us that neither it, nor any of its subsidiaries or affiliates, has engaged in any conduct that would be sanctionable under any of these legal regimes.
