PART I

Item 1 and 2. Business and Properties .

General

We are a publicly traded Delaware limited partnership, the common units of which are listed on the New York Stock Exchange (“NYSE”) under the ticker symbol “EPD.” We were formed in April 1998 to own and operate certain natural gas liquids (“NGLs”) related businesses of EPCO and are now a leading North American provider of midstream energy services to producers and consumers of natural gas, NGLs, crude oil, refined products and certain petrochemicals. Our 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 assets include approximately 50,600 miles of onshore and offshore pipelines; 190 MMBbls of storage capacity for NGLs, crude oil, refined products and certain petrochemicals; and 14 Bcf of natural gas storage capacity.

Our midstream energy operations include: natural gas gathering, treating, processing, transportation and storage; NGL transportation, fractionation, storage, and import and export terminaling; crude oil and refined products transportation, storage, and terminaling; offshore production platforms; petrochemical transportation and services; and a marine transportation business that operates primarily on the U.S. inland and Intracoastal Waterway systems and in the Gulf of Mexico. We have six reportable business segments: (i) NGL Pipelines & Services; (ii) Onshore Natural Gas Pipelines & Services; (iii) Onshore Crude Oil Pipelines & Services; (iv) Offshore Pipelines & Services; (v) Petrochemical & Refined Products Services; and (vi) Other Investments.

We conduct substantially all of our business through EPO and are owned 100% by our limited partners from an economic perspective. Enterprise GP owns a non-economic general partner interest in us. Our principal executive offices are located at 1100 Louisiana Street, 10 th Floor, Houston, Texas 77002, our telephone number is (713) 381-6500 and our website address is www.enterpriseproducts.com .

Business Strategy

We operate an integrated network of midstream energy assets. Our business strategies are to:

capitalize on expected increases in the production of natural gas, NGLs and crude oil from development activities in various producing basins including the Rocky Mountains, Midcontinent, Northeast and U.S. Gulf Coast regions, deepwater Gulf of Mexico and developing shale plays including the Barnett, Eagle Ford, Haynesville, Marcellus, Mancos and Utica Shales;

§	capitalize on expected demand growth for natural gas, NGLs, crude oil and petrochemical and refined products;

§	maintain a diversified portfolio of midstream energy assets and expand this asset base through growth capital projects and accretive acquisitions of complementary midstream energy assets;

§	enhance the stability of our cash flows by investing in pipelines and other fee-based businesses; and

§	share capital costs and risks through joint ventures or alliances with strategic partners, including those that will provide the raw materials for these growth capital projects or purchase the projects’ end products.

As noted above, part of our business strategy involves expansion through growth capital projects. We expect that these projects will enhance our existing asset base and provide us with additional growth opportunities in the future.

Duncan Merger

In September 2011, the Duncan Merger Agreement was approved by the unitholders of Duncan Energy Partners and the merger of Duncan MergerCo and Duncan Energy Partners and related transactions were completed, with Duncan Energy Partners surviving such merger as our wholly owned subsidiary. Each issued and outstanding common unit of Duncan Energy Partners was cancelled and converted into the right to receive our limited partner common units based on an exchange ratio of 1.01 Enterprise common units for each Duncan Energy Partners common unit. We issued 24,277,310 of our common units (net of fractional common units cashed out) to the former public unitholders of Duncan Energy Partners as consideration in the Duncan Merger. We did not issue any common units as merger consideration to our subsidiaries that owned limited partner interests in Duncan Energy Partners.

Holdings Merger

In November 2010, the Holdings Merger Agreement was approved by the unitholders of Holdings and the merger of Holdings with Holdings MergerCo and related transactions were completed, with Holdings MergerCo surviving such merger. At the effective time of the Holdings Merger, Enterprise GP succeeded as our general partner, and each issued and outstanding unit representing limited partner interests in Holdings was cancelled and converted into the right to receive our common units based on an exchange ratio of 1.5 Enterprise common units for each Holdings unit. We issued an aggregate of 208,813,454 of our common units (net of fractional common units cashed out) as consideration in the Holdings Merger and, immediately after the merger, cancelled 21,563,177 of our common units previously owned by Holdings.

In connection with the Holdings Merger, a privately held affiliate of EPCO agreed to temporarily waive the regular quarterly cash distributions it would otherwise receive from us with respect to a certain number of our common units (the “Designated Units”) it owned over a five-year period after the merger closing date of November 22, 2010. The number of Designated Units to which the temporary distribution waiver applies is as follows for distributions paid or to be paid, if any, during the following calendar years: 30,610,000 during 2011; 26,130,000 during 2012; 23,700,000 during 2013; 22,560,000 during 2014; and 17,690,000 during 2015. Distributions paid to partners during calendar year 2011 excluded the initial 30,610,000 Designated Units; however, distributions to be paid, as applicable, to partners in calendar year 2012 (beginning with the February 2012 distribution) will exclude 26,130,000 Designated Units. As a result, the number of our distribution-bearing units increased by 4,480,000 units

Table of Contents

beginning with the February 2012 distribution and will increase in subsequent years as the number of Designated Units declines.

Basis of Financial Statement Presentation

As a result of the Holdings Merger, Enterprise’s consolidated financial and operating results prior to November 22, 2010 have been presented as if Enterprise were Holdings from an accounting perspective (i.e., the financial statements of Holdings became the historical financial statements of Enterprise). See Note 1 of the Notes to Consolidated Financial Statements included under Item 8 of this annual report for information regarding the basis of presentation of our general purpose financial statements. Such information is incorporated by reference into this Item 1 and 2 discussion.

Since we historically consolidated Duncan Energy Partners for financial reporting purposes, the Duncan Merger did not change the basis of presentation of our historical financial statements.

Significant Growth Capital Projects

An integral 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 system of assets through the construction of new facilities and to capitalize on expected increases in the production of natural gas, NGLs and crude oil from development activities in various producing basins including the Rocky Mountains, Midcontinent, Northeast and U.S. Gulf Coast regions, deepwater Gulf of Mexico and developing shale plays including the Barnett, Eagle Ford, Haynesville, Marcellus, Mancos and Utica Shales. Our growth projects are typically supported by long-term producer and shipper dedications. We have a number of significant growth capital projects currently underway including the following:

In November 2011, we and Enbridge Inc. agreed to reverse the direction of crude oil flows on the Seaway pipeline to enable it to transport oil from the oversupplied Cushing hub to U.S. Gulf Coast refiners. The Seaway pipeline could operate in reversed service with an initial capacity of 150 MBPD during the second quarter of 2012. Following pump station additions and other modifications, which are anticipated to be completed in the first quarter of 2013, we anticipate the capacity of the reversed Seaway pipeline will be up to 400 MBPD (assuming a mix of light and heavy grades of crude oil). In addition, we are constructing related storage assets and connecting pipelines in the Houston, Texas area that are expected to be completed in mid-2012 and early 2014, respectively.

In November 2011, we announced several new construction projects, including an expansion of our new Yoakum natural gas processing facility, which would extend and expand our natural gas and NGL infrastructure in South Texas to accommodate expected production growth from the Eagle Ford Shale. We expect the Yoakum facility and related assets to commence operations in phases beginning in the second quarter of 2012 and continuing into the first quarter of 2013. In addition to the Yoakum expansion, we are constructing 62 miles of natural gas pipeline loops and increasing our pipeline compression to gather and transport additional quantities of liquids-rich gas from the Eagle Ford Shale. These pipeline expansion projects are also expected to begin service in the first quarter of 2013.

Table of Contents

In October 2011, we placed into service our fifth Mont Belvieu NGL fractionator, which has a nameplate capacity of 75 MBPD, and increased the total nameplate NGL fractionation capacity at our Mont Belvieu facility to 380 MBPD. In June 2011, we announced plans to construct a sixth NGL fractionator at our Mont Belvieu, Texas facility. The new fractionator will also have a nameplate capacity of 75 MBPD and accommodate NGLs from the continued growth of liquids-rich natural gas production from the Eagle Ford Shale and other producing areas. We have started construction of the new fractionator and we expect it to begin service in late 2012. Upon completion of the sixth NGL fractionator, we will have the capability to fractionate more than 450 MBPD of NGLs at our Mont Belvieu complex.

In May 2011, we announced plans to build an 80-mile extension (the second phase) of our South Texas Crude Oil Pipeline System, which would allow us to serve growing production areas in the southwestern portion of the Eagle Ford Shale supply basin. This extension is expected to be placed into service during the first quarter of 2013. The first phase of our South Texas Crude Oil Pipeline System expansion project comprises 140-miles of pipeline and is expected to begin service by the second quarter of 2012.

In May 2011, we announced plans to expand our Mont Belvieu polymer grade propylene (“PGP”) fractionation facility to accommodate increased PGP demand. When completed, the expansion project will increase our net capacity to produce PGP by more than 10% from 73 MBPD (approximately 4.9 billion pounds per year) to 80.5 MBPD (approximately 5.4 billion pounds per year). The expansion is expected to be in service in the first quarter of 2013.

In March 2011, we announced an expansion of our primary Houston Ship Channel import/export terminal. This expansion project is expected to nearly double the terminal’s fully refrigerated export loading capacity for propane and other NGLs to more than 10,000 barrels per hour, while enhancing the terminal’s ability to load multiple vessels simultaneously. We expect to complete this expansion project in the second half of 2012.

In March 2011, we announced an expansion project involving the Rocky Mountain segment of our Mid-America Pipeline System. The Rocky Mountain pipeline expansion involves looping the existing system with approximately 218 miles of 16-inch diameter pipeline, as well as pump station modifications. This expansion project is expected to add 62.5 MBPD of transportation capacity to the Rocky Mountain pipeline’s existing capacity of approximately 275 MBPD (after taking into account shipper commitments announced in January 2012). This expansion project is expected to begin service in the third quarter of 2014.

For additional information regarding these significant growth capital projects and other recent developments, see “Significant Recent Developments” under Item 7 of this annual report.

For the year ended December 31, 2011, we spent $3.55 billion on growth capital projects, of which approximately $867 million was for the Haynesville Extension and $1.59 billion for Eagle Ford Shale projects. Based on information currently available, we estimate our consolidated capital spending for 2012 will approximate $3.8 billion, which includes estimated expenditures of $3.5 billion for growth capital projects and $315 million for sustaining capital expenditures. For additional information regarding our capital spending program, see “Liquidity and Capital Resources—Capital Spending” under Item 7 of this annual report.

Business Segment Discussion

Our midstream energy asset network links producers of natural gas, NGLs and crude oil from some of the largest supply basins in the U.S., Canada and the Gulf of Mexico with domestic consumers and international markets. We have six reportable business segments: NGL Pipelines & Services; Onshore Natural Gas Pipelines & Services; Onshore Crude Oil Pipelines & Services; Offshore Pipelines & Services; Petrochemical & Refined Products Services; and Other Investments.

Our business segments are generally organized and managed according to the type of services rendered (or technologies employed) and products produced and/or sold.

The following sections present an overview of our business segments, including information regarding the principal products produced, services rendered, properties owned, seasonality and competition. Our results of operations and financial condition are subject to a variety of risks. For information regarding our risk factors, see Item 1A of this annual report.

Our business activities are subject to various federal, state and local laws and regulations governing a wide variety of topics, including commercial, operational, environmental, safety and other matters. For a discussion of the principal effects such laws and regulations have on our business, see “—Regulation” and “—Environmental and Safety Matters” included within this Item 1 and 2.

Our consolidated revenues are derived from a wide customer base. Our largest non-affiliated customer for 2011, 2010 and 2009 was Shell Oil Company and its affiliates, which accounted for 10.6%, 9.4% and 9.8% of our consolidated revenues, respectively.

For information regarding our results of operations, including significant measures of historical throughput, production and processing volumes, see Item 7 of this annual report. In addition, certain of our operations entail the use of derivative instruments. For information regarding our use of commodity derivative instruments, see Note 6 of the Notes to Consolidated Financial Statements included under Item 8 of this annual report.

Financial Information by Business Segment

For detailed financial information regarding our business segments, see Note 14 of the Notes to Consolidated Financial Statements included under Item 8 of this annual report. Such financial information is incorporated by reference into this Item 1 and 2 discussion.

NGL Pipelines & Services

Our NGL Pipelines & Services business segment includes our: (i) natural gas processing business and related NGL marketing activities; (ii) NGL pipelines aggregating approximately 16,650 miles; (iii) NGL and related product terminal and storage facilities with approximately 156 MMBbls of net usable storage capacity; and (iv) 13 NGL fractionators. This segment also includes our import and export terminal operations.

NGL products (ethane, propane, normal butane, isobutane and natural gasoline) are used as raw materials by the petrochemical industry, as feedstocks by refiners in the production of motor gasoline and by industrial and residential users as fuel. Ethane is primarily used in the petrochemical industry as a feedstock for ethylene production, one of the basic building blocks for a wide range of plastics and other chemical products. Propane is used both as a petrochemical feedstock in the production of ethylene and propylene and as a heating, engine and industrial fuel. Normal butane is used as a petrochemical feedstock in the production of ethylene and butadiene (a key ingredient of synthetic rubber), as a blendstock for motor gasoline and to produce isobutane through isomerization. Isobutane is fractionated from mixed butane (a mixed stream of normal butane and isobutane) or produced from normal butane through the process of isomerization, and is used in refinery alkylation to enhance the octane content of motor gasoline, in the production of isooctane and other octane additives and in the production of propylene oxide. Natural gasoline, a mixture of pentanes and heavier hydrocarbons, is primarily used as a blendstock for motor gasoline or as a petrochemical feedstock.

Table of Contents

Natural gas processing and related NGL marketing activities . At the core of our natural gas processing business are 24 processing plants located across Colorado, Louisiana, Mississippi, New Mexico, Texas and Wyoming. Natural gas produced at the wellhead (especially in association with crude oil) contains varying amounts of NGLs. This liquids-rich natural gas in its raw form is usually not acceptable for transportation in the nation’s natural gas pipeline systems or for commercial use as a fuel. Natural gas processing plants remove NGLs from the natural gas stream, which enables the natural gas to meet pipeline and commercial quality specifications. In addition, on an energy equivalent basis, NGLs generally have a greater economic value as a raw material for petrochemical and motor gasoline production than their value as components of a natural gas stream. After extraction by the processing plants, we typically transport the mixed NGLs to a centralized facility for fractionation into purity NGL products such as ethane, propane, normal butane, isobutane and natural gasoline. The purity NGL products can then be used in our NGL marketing activities to meet contractual requirements or sold on spot and forward markets. Also, we purchase natural gas from producers in connection with our natural gas processing activities. Once processed, this natural gas is available for sale through our natural gas marketing activities.

When operating and extraction costs of natural gas processing plants are higher than the incremental value of the NGL products that would be extracted, the recovery levels of certain NGL products, principally ethane, may be reduced or eliminated. This leads to a reduction in NGL volumes available for transportation and fractionation.

In our natural gas processing business, we enter into fee-based contracts, keepwhole and margin-band contracts, percent-of-liquids contracts, percent-of-proceeds contracts, and hybrid contracts (i.e., a combination of percent-of-liquids and fee-based contract terms). If a cash fee for natural gas processing services is stipulated by the contract, we record revenue when the natural gas has been processed and delivered to the producer. Under keepwhole and margin-band contracts, we take ownership of mixed NGLs extracted from the producer’s natural gas stream and recognize revenue when the extracted NGLs are delivered and sold to customers under NGL marketing sales contracts. Revenue under our percent-of-liquids contracts is recognized the same way, except that the volume of NGLs we take ownership of is less than the total amount of NGLs extracted from the producers’ natural gas. Under a percent-of-liquids contract, the producer retains title to a percentage of the mixed NGLs we extract and generally bears the cost of natural gas associated with shrinkage and plant fuel. The value of natural gas lost as a result of NGL extraction (i.e., shrinkage) and consumed as plant fuel is referred to as plant thermal reduction (“PTR”). Under a percent-of-proceeds contract, we share in the proceeds generated from the sale of the mixed NGLs we extract on the producer’s behalf. The NGL volumes we earn and take title to in connection with our processing activities are referred to as our equity NGL production.

In general, our percent-of-liquids, hybrid and keepwhole contracts give us the right (but not the obligation) to process natural gas for a producer; thus, we are protected from processing natural gas at an economic loss during times when the sum of our costs exceeds the value of the mixed NGLs in which we would take ownership. Generally, our natural gas processing agreements have terms ranging from month-to-month to life of the producing lease. Intermediate terms of one to ten years are also common.

To the extent that we are obligated under our keepwhole and margin-band contracts to compensate the producer for the natural gas equivalent energy value of mixed NGLs we extract from the natural gas stream, we are exposed to various risks, primarily commodity price fluctuations. However, our margin band contracts typically contain terms which limit our exposure to such risks. The prices of natural gas and NGLs are subject to fluctuations in response to changes in supply and demand and a variety of additional factors that are beyond our control. Periodically, we attempt to mitigate these risks through the use of commodity derivative instruments (e.g., fixed-price natural gas purchases and NGL sales contracts).

Our NGL marketing activities generate revenues from the sale and delivery of NGLs we take title to through our natural gas processing activities (i.e., our equity NGL production) and open market and contract purchases from third parties. Our NGL marketing sales contracts may also include forward product sales contracts. In general, sales prices referenced in the contracts utilized within our NGL marketing activities are market-based and may include pricing differentials for such factors as delivery location. The majority of our consolidated revenues and costs and expenses are generated from marketing activities, including those associated with NGLs. Changes in our consolidated revenues and operating costs and expenses period-to-period are explained in part by changes in market prices for the products we sell. The results of operations from our NGL marketing activities are generally dependent upon the volume of products sold and the sales prices charged to customers. The volume of

Table of Contents

products sold may fluctuate from period-to-period depending on market conditions, volumes produced and opportunities, which may be influenced by current and forward market prices for purity NGL products and our hedging activities.

For additional information regarding our inventories and consolidated segment revenues and expenses, see Notes 7 and 14, respectively, of the Notes to Consolidated Financial Statements included under Item 8 of this annual report.

NGL pipelines, storage and terminal facilities and import/export operations . Our NGL pipelines transport mixed NGLs and other hydrocarbons from natural gas processing facilities, refineries and import terminals to fractionation plants and storage facilities; distribute and collect purity NGL products to and from fractionation plants, storage and terminal facilities, petrochemical plants, export facilities and refineries; and deliver propane to customers along the Dixie Pipeline and certain sections of the Mid-America Pipeline System. Revenues from our NGL pipeline transportation agreements are generally based upon a fixed fee per gallon of liquids transported multiplied by the volume delivered. Accordingly, the results of operations for this business are generally dependent upon the volume of product transported and the level of fees charged to customers (including those charged internally, which are eliminated in the preparation of our Consolidated Financial Statements). Certain of our NGL pipelines offer firm capacity reservation services whereby the shipper pays a contractually stated fee based on the level of throughput capacity reserved in our pipelines whether or not the shipper actually utilizes such capacity. Fees charged for NGL transportation services are either contractual or regulated by governmental agencies, including the Federal Energy Regulatory Commission (“FERC”). Excluding inventories held in connection with our marketing activities, we typically do not take title to the products transported by our NGL pipelines; rather, the shipper retains title and the associated commodity price risk. However, we occasionally act as shipper for certain volumes being transported.

Our NGL and related product storage facilities are integral parts of our operations used for the storage of products owned by us and our customers. In general, our underground salt dome storage caverns (or wells) are used to store mixed NGLs and purity NGL, petrochemical and refined products. We collect storage revenues under our NGL and related product storage contracts based on the number of days a customer has volumes in storage multiplied by a storage fee (as defined in each contract). With respect to capacity reservation agreements, we collect a fee for reserving storage capacity for certain customers in our underground storage wells. Customers pay reservation fees based on the level of storage capacity reserved rather than the actual volumes stored. When a customer exceeds its reserved capacity, we charge those customers an excess storage fee. In addition, we generally charge customers throughput fees based on volumes delivered into and subsequently withdrawn from storage. Accordingly, the profitability of our storage operations is dependent upon the level of storage capacity reserved by customers, the volume of product delivered into and withdrawn from the underground caverns and the level of fees charged.

We operate NGL import and export facilities located on the Houston Ship Channel in southeast Texas and an NGL terminal in Providence, Rhode Island with ship unloading capabilities. In addition, we operate NGL terminal facilities in 22 states that are connected to our pipelines and/or support our NGL marketing activities. Our NGL import facility is primarily used to offload volumes for delivery to our storage and fractionation facilities located in Mont Belvieu, Texas. Our NGL export facility is used for loading refrigerated marine tankers for customers. Revenues from our terminal services are primarily based on fees per unit of volume loaded or unloaded and may also include demand payments if minimum volume commitments are not met or the terminaling contracts are cancelled. Accordingly, the profitability of our NGL terminal activities primarily depends on the available quantities of NGLs to be loaded and offloaded and the fees we charge for these services.

NGL fractionation . We own or have interests in 13 NGL fractionators located in Texas, Louisiana and Ohio. NGL fractionators separate mixed NGL streams into purity NGL products. The primary sources of mixed NGLs fractionated in the U.S. are domestic natural gas processing plants, crude oil refineries and imports of butane and propane mixtures. Mixed NGLs sourced from domestic natural gas processing plants and crude oil refineries are typically transported by NGL pipelines and, to a lesser extent, by railcar and truck to NGL fractionation facilities.

Table of Contents

Mixed NGLs extracted by domestic natural gas processing plants represent the largest source of volumes processed by our NGL fractionators. Based upon industry data, we believe that sufficient volumes of mixed NGLs, especially those originating from Gulf Coast, Rocky Mountain and Midcontinent natural gas processing plants, will be available for fractionation in commercially viable quantities for the foreseeable future. Significant volumes of mixed NGLs are contractually committed to be processed at our NGL fractionators by joint owners and third party customers.

Our NGL fractionation facilities process mixed NGL streams for third party customers and support our NGL marketing activities. We typically earn revenues from NGL fractionation under fee-based arrangements, including a significant level of demand-based fees. These fees (usually stated in cents per gallon) are contractually subject to adjustment for changes in certain fractionation expenses (e.g., natural gas fuel costs). At our Norco facility in Louisiana, we perform fractionation services for certain customers under percent-of-liquids contracts. The results of operations of our NGL fractionation business are generally dependent upon the volume of mixed NGLs fractionated and either the level of fractionation fees charged (under fee-based contracts) or the value of NGLs received (under percent-of-liquids arrangements). Our fee-based fractionation customers retain title to the NGLs that we process for them. To the extent we fractionate volumes for customers under percent-of-liquids contracts, we are exposed to fluctuations in NGL prices (i.e., commodity price risk). Periodically, we attempt to mitigate these risks through the use of commodity derivative instruments such as forward sales contracts.

Seasonality . Our natural gas processing and NGL fractionation operations typically exhibit little to no seasonal variation. Our NGL marketing activities rely on inventories of purity NGL products. Propane and normal butane inventories are typically at higher levels from March through November since these products are normally in higher demand and at higher price levels during the winter months. Ethane, isobutane and natural gasoline inventories are generally stable and less cyclical throughout the year.

NGL pipeline transportation volumes are generally higher from October through March due to higher demand for propane (for residential heating) and normal butane (for blending into motor gasoline). With respect to our NGL and related product storage facilities, we usually experience an increase in demand for storage services during the spring and summer months due to increased feedstock storage requirements for motor gasoline production and a decrease during the fall and winter months when propane inventories are being drawn down for heating needs. Likewise, the revenues we recognize from NGL marketing activities are predicated on the overall demand for such products, which may fluctuate due to seasonal needs for gasoline blending feedstocks, heating requirements and similar factors. In general, our import volumes peak during the spring and summer months and our export volumes are typically at their highest levels during the winter months. Lastly, our facilities located along the Gulf Coast of the U.S. may be affected by weather events such as hurricanes and tropical storms, which generally arise during the summer and fall months.

Competition . Within their respective market areas, our natural gas processing business activities and related NGL marketing activities encounter competition from fully integrated oil companies, intrastate pipeline companies, major interstate pipeline companies and their non-regulated affiliates, financial institutions with trading platforms and independent processors. Each of our marketing competitors has varying levels of financial and personnel resources, and competition generally revolves around price, quality of customer service and proximity to customers and other market hubs. In the markets served by our NGL pipelines, we compete with a number of intrastate and interstate pipeline companies (including those affiliated with major oil, petrochemical and natural gas companies) and barge, rail and truck fleet operations. In general, our NGL pipelines compete with these entities in terms of transportation fees and quality of customer service.

Our primary competitors in the NGL and related product storage businesses are integrated major oil companies, chemical companies and other storage and pipeline companies. We compete with other storage service providers primarily in terms of the fees charged, number of pipeline connections provided and operational dependability. Our import and export operations compete with those operated by major oil and chemical companies primarily in terms of loading and offloading throughput capacity.

We compete with a number of NGL fractionators in Texas, Louisiana, New Mexico and Kansas. Competition for such services is primarily based on the fractionation fee charged. However, the ability of an NGL

Table of Contents

fractionator to receive a customer’s mixed NGLs and store and distribute its purity NGL products is also an important competitive factor and is a function of having the necessary pipeline and storage infrastructure.

(1) The approximate net gas processing capacity does not necessarily correspond to our ownership interest in each facility. It is based on a variety of factors such as the level of volumes an owner processes at the facility and its ownership interest in the facility. (2) We proportionately consolidate our undivided interest in these operating assets. (3) Our ownership in the Venice plant is held indirectly through our equity method investment in Venice Energy Services Company, L.L.C. (“VESCO”).

Our natural gas processing facilities can be characterized as two distinct types: (i) straddle plants situated on mainline natural gas pipelines owned either by us or by third parties or (ii) field plants that process natural gas from gathering pipelines. We operate the Meeker, Pioneer, Toca, Chaco, North Terrebonne, Neptune, Burns Point, Carlsbad and Chaparral plants and all of the Texas facilities. On a weighted-average basis, utilization rates for these assets were 56.1%, 51.2% and 48.3% during the years ended December 31, 2011, 2010 and 2009, respectively. These rates reflect the periods in which we owned an interest in such facilities.

Our NGL marketing activities utilize a fleet of approximately 500 railcars, the majority of which are leased from third parties. These railcars are used to deliver feedstocks to our facilities and to distribute NGLs throughout the U.S. and parts of Canada. We have rail loading and unloading capabilities at certain of our terminal facilities in Alabama, Arizona, California, Kansas, Louisiana, Minnesota, Mississippi, Nevada, New York, North Carolina and Texas. These facilities service both our rail shipments and those of our customers.

(1) In December 2011, we acquired the remaining 10% ownership interest in Seminole Pipeline Company (“Seminole”). (2) Our ownership interest in the Skelly-Belvieu Pipeline is held indirectly through our equity method investment in Skelly-Belvieu Pipeline Company, L.L.C. (“Skelly-Belvieu”). (3) Our ownership interest in the Promix NGL Gathering System is held indirectly through our equity method investment in K/D/S Promix, L.L.C. (“Promix”). (4) We own a 70% consolidated interest in the Rio Grande Pipeline through our majority owned subsidiary, Rio Grande Pipeline Company. (5) We own an 83.3% consolidated interest in the Tri-States NGL Pipeline through our majority owned subsidiary, Tri-States NGL Pipeline, L.L.C. (6) Includes our Belle Rose and Wilprise pipelines located in the coastal regions of Louisiana and Mississippi; Port Arthur pipelines located in southeast Texas; and our Meeker pipeline in Colorado. (7) We own a 74.7% consolidated interest in the 30-mile Wilprise pipeline through our majority owned subsidiary, Wilprise Pipeline Company, LLC. We proportionately consolidate our 50% undivided interest in a 45-mile segment of the Port Arthur pipelines. The remainder of these NGL pipelines are wholly owned. (8) The amount shown for Texas includes 34 underground NGL, petrochemical and refined products storage caverns with an aggregate working capacity of approximately 100 MMBbls. These 34 caverns are located in Mont Belvieu, Texas. (9) Includes storage capacity at our facilities in Alabama, Arizona, California, Georgia, Illinois, Indiana, Iowa, Minnesota, Missouri, Nebraska, Nevada, New York, North Carolina, Ohio, Oklahoma, Pennsylvania, Rhode Island, South Carolina and Wisconsin. (10) Our underground storage caverns and above ground storage tanks have an aggregate 155.8 MMBbls of net usable storage capacity. Our aggregate net usable storage capacity includes 21.3 MMBbls held under long-term operating leases at facilities located in Indiana, Kansas, Louisiana and Texas. Approximately 2 MMBbls of our net usable storage capacity in Louisiana is held indirectly through our equity method investments in Promix and Baton Rouge Fractionators LLC (“BRF”). The remainder of our NGL underground storage caverns and above ground storage tanks are wholly owned.

The maximum number of barrels that our NGL pipelines can transport per day depends upon the operating balance achieved at a given point in time between various segments of the systems. Since the operating balance is dependent upon the mix of products being shipped and demand levels at various delivery points, the exact capacities of our NGL pipelines cannot be reliably determined. We measure the utilization rates of such pipelines in terms of net throughput, which is based on our ownership interest. Total net throughput volumes for these pipelines were 2,180 MBPD, 2,207 MBPD and 2,099 MBPD during the years ended December 31, 2011, 2010 and 2009, respectively.

The following information highlights the general use of each of our principal NGL pipelines. We operate our NGL pipelines with the exception of the Tri-States pipeline.

The Mid-America Pipeline System is a regulated NGL pipeline system consisting of four primary segments: the 2,932-mile Rocky Mountain pipeline, the 2,148-mile Conway North pipeline, the 621-mile Ethane-Propane Mix pipeline and the 2,222-mile Conway South pipeline. The Mid-America Pipeline System is present in 13 states: Colorado, Illinois, Iowa, Kansas, Minnesota, Missouri, Nebraska, New Mexico, Oklahoma, Texas, Utah, Wisconsin and Wyoming. The Rocky Mountain pipeline transports mixed NGLs from the Rocky Mountain Overthrust and San Juan Basin areas to the Hobbs hub located on the Texas-New Mexico border. The Conway North segment links the NGL hub at Conway, Kansas to refineries, petrochemical plants and propane markets in the upper Midwest. In addition, the Conway North segment has access to NGL supplies from Canada’s Western Sedimentary Basin through third party connections. Effective January 1, 2011, a separate tariff was filed for the Ethane-Propane Mix segment, which was formerly treated as part of the Conway North segment. The Ethane-Propane Mix segment transports ethane/propane mix primarily to petrochemical plants in Illinois from the NGL hub at Conway and other origin points in Illinois and Iowa. The Conway South pipeline connects the Conway hub with Kansas refineries and provides bi-directional transportation of NGLs between Conway, Kansas and the Hobbs hub. The Mid-America Pipeline System interconnects with our Seminole Pipeline and Hobbs NGL fractionation and storage facility at the Hobbs hub. This system includes 14 unregulated propane terminals.

During 2011, approximately 52% of the volumes transported on the Mid-America Pipeline System were mixed NGLs originating from natural gas processing plants. The remaining volumes consisted of purity NGL products originating from NGL fractionators located in Kansas, Oklahoma and Texas, as well as deliveries from Canada.

The Seminole Pipeline is a regulated pipeline that transports NGLs from the Hobbs hub and the Permian Basin area of West Texas to markets in southeast Texas including our NGL fractionation facility in Mont Belvieu, Texas. NGLs originating on the Mid-America Pipeline System are the primary source of throughput for the Seminole Pipeline.

The South Texas NGL System is a network of NGL gathering and transportation pipelines located in South Texas. The system gathers and transports mixed NGLs from our South Texas natural gas processing plants to our South Texas NGL fractionators. In turn, the system transports purity NGL products from our South Texas NGL fractionators to refineries and petrochemical plants located between Corpus Christi, Texas and Houston, Texas and within the Texas City-Houston area, as well as to interconnects with common carrier NGL pipelines. The South Texas NGL System also connects our South Texas NGL fractionators with our storage facility in Mont Belvieu, Texas.

The Dixie Pipeline is a regulated pipeline that extends from southeast Texas and Louisiana to markets in the southeastern U.S. and transports propane and other NGLs. Propane supplies transported on this system primarily originate from southeast Texas, south Louisiana and Mississippi. This system includes eight unregulated propane terminals and operates in seven states: Texas, Louisiana, Mississippi, Alabama, Georgia, South Carolina and North Carolina.

§	The Chaparral NGL System transports NGLs from natural gas processing plants in West Texas and New Mexico to Mont Belvieu, Texas. This system consists of the 831-mile regulated Chaparral pipeline and the 180-mile unregulated Quanah pipeline.

The Louisiana Pipeline System is a network of NGL pipelines located in southern Louisiana. This system transports NGLs originating in Louisiana and Texas to refineries and petrochemical plants located along the Mississippi River corridor in southern Louisiana. This system also provides transportation services for our natural gas processing plants, NGL fractionators and other assets located in Louisiana. Originating from a central point in Henry, Louisiana, pipelines extend westward to Lake Charles, Louisiana, northward to an interconnect with the Dixie Pipeline at Breaux Bridge, Louisiana and eastward in Louisiana, where our Promix, Norco and Tebone NGL fractionation and Sorrento storage facilities are located.

The Skelly-Belvieu Pipeline is a regulated pipeline that transports mixed NGLs from Skellytown, Texas to Mont Belvieu, Texas. The Skelly-Belvieu Pipeline receives NGLs through a pipeline interconnect with our Mid-America Pipeline System in Skellytown, Texas. We became operator of this pipeline in January 2011.

§	The Promix NGL Gathering System gathers mixed NGLs from natural gas processing plants in southern Louisiana for delivery to our Promix NGL fractionator.

§	The Houston Ship Channel pipeline system connects our Mont Belvieu, Texas facilities with our Houston Ship Channel import/export terminals and various third party petrochemical plants, refineries and other pipelines located along the Houston Ship Channel.

§	The Rio Grande Pipeline is a regulated pipeline originating near Odessa, Texas that transports mixed NGLs to a pipeline interconnect at the Mexican border south of El Paso, Texas.

§	The Lou-Tex NGL Pipeline system transports NGLs and refinery grade propylene between the Louisiana and Texas markets.

In January 2012, we announced the receipt of sufficient transportation commitments to support development of our 1,230-mile ATEX Express that will transport growing ethane production from the Marcellus and Utica Shale producing areas of Pennsylvania, West Virginia and Ohio to the U.S. Gulf Coast. We expect that the ATEX Express will begin commercial operations in the first quarter of 2014. For additional information regarding this growth capital project, see “Significant Recent Developments—Development of Our ATEX Express Long-Haul Ethane Pipeline” under Item 7 of this annual report.

Our NGL and related product storage and terminal facilities are integral components of our midstream energy infrastructure. We operate these storage and terminal facilities, with the exception of certain Louisiana storage locations, the leased Markham facility in Texas and a leased facility in Kansas that are operated for us by third parties.

Our largest underground storage facility is located in Mont Belvieu, Texas. This storage facility consists of 34 underground NGL, petrochemical and refined products salt dome storage caverns with an aggregate usable storage capacity of approximately 100 MMBbls, a brine system with approximately 20 MMBbls of above-ground brine storage pit capacity and two brine production wells. These assets store and deliver NGLs (such as ethane and propane) and certain petrochemical products for industrial customers located along the upper Texas Gulf Coast.

In February 2011, we experienced an NGL release and fire at the West Storage location of our Mont Belvieu, Texas underground storage facility. West Storage consists of ten underground salt dome storage caverns with a storage capacity of approximately 15 MMBbls. Through the reconfiguration of product receipt and delivery capabilities and other measures, we readily returned our Mont Belvieu plants and related assets to close to the same capabilities as we had prior to the incident; however, our West Storage location and associated underground storage wells remain partially inoperative at this time. Remaining repairs to this location are underway and are expected to be completed in stages by mid-2012.

(1) The approximate net plant capacity does not necessarily correspond to our ownership interest in each facility. It is based on a variety of factors such as the level of volumes an owner processes at the facility and its ownership interest in the facility. (2) There are five NGL fractionators located at our Mont Belvieu, Texas facility. Our fifth NGL fractionator commenced commercial operations at this facility in October 2011. (3) We proportionately consolidate our 75% undivided interest in four of the NGL fractionators located at our Mont Belvieu, Texas facility. The fifth NGL fractionator at this facility is wholly owned. (4) Our ownership interest in the Promix fractionator is held indirectly through our equity method investment in Promix. (5) Our ownership interest in the BRF fractionator is held indirectly through our equity method investment in BRF. (6) We proportionately consolidate our undivided interest in the Tebone fractionator.

In March 2011, we sold two small NGL fractionation facilities located in northeast Colorado for approximately $30.0 million in cash. These assets were not integrated with our other midstream energy assets.

The following information highlights the general use of each of our principal NGL fractionators. We operate all of our NGL fractionators.

Our Mont Belvieu NGL fractionation facility is located in Mont Belvieu, Texas, which is a key hub of the NGL industry. This facility fractionates mixed NGLs from several major NGL supply basins in North America, including the Mid-Continent, Permian Basin, San Juan Basin, Rocky Mountains, East Texas and the Gulf Coast.

In June 2011, we announced plans to construct a sixth NGL fractionator at our Mont Belvieu, Texas facility. The new fractionation facility will have a nameplate capacity of 75 MBPD and accommodate continued growth of liquids-rich natural gas production from the Eagle Ford Shale and other producing areas. We have obtained all necessary approvals and permits and have started construction of the new facility, which is projected to begin service in late 2012. Upon completion of the sixth NGL fractionator, we expect to have the capability to fractionate more than 450 MBPD of NGLs at our Mont Belvieu complex.

Our Shoup and Armstrong fractionators process mixed NGLs supplied by our South Texas natural gas processing plants. Purity NGL products from the Shoup and Armstrong fractionators are transported to local markets in the Corpus Christi area and also to Mont Belvieu, Texas using our South Texas NGL System.

Our Hobbs NGL fractionator is located in Gaines County, Texas, where it serves petrochemical plants and refineries in West Texas, New Mexico, California and northern Mexico. The Hobbs fractionator receives mixed NGLs from several major supply basins, including Mid-Continent, Permian Basin, San Juan Basin and the Rocky Mountains. The facility is located at the interconnect of our Mid-America Pipeline System and Seminole Pipeline, thus providing us the flexibility to supply the nation’s largest NGL hub at Mont Belvieu, Texas as well as access to the second-largest NGL hub at Conway, Kansas.

The Promix NGL fractionator receives mixed NGLs via pipeline from natural gas processing plants located in southern Louisiana and along the Mississippi Gulf Coast, including from our Neptune, Burns Point and Pascagoula facilities. In addition to the Promix NGL Gathering System (described previously), Promix owns three NGL storage caverns and a barge loading facility that are integral to its operations. Promix leases a fourth NGL storage cavern.

§	The BRF fractionator receives mixed NGLs from natural gas processing plants located in Alabama, Mississippi and southern Louisiana.

On a weighted-average basis, utilization rates for our NGL fractionators were 90.2%, 90.7% and 88.8% during the years ended December 31, 2011, 2010 and 2009, respectively. These rates reflect the periods in which we owned an interest in such facilities or, for recently constructed facilities, since the dates such assets were placed into service.

Our NGL operations include import and export facilities located on the Houston Ship Channel in southeast Texas. We own an import and export facility located on land we lease from Oiltanking Houston LP. Our import facility can offload NGLs from tanker vessels at rates up to 14,000 barrels per hour depending on the product. Our export facility can load cargoes of refrigerated propane and butane onto tanker vessels at rates up to 6,700 barrels per hour. In addition to these facilities, we own a barge dock also located on the Houston Ship Channel that can load or offload two barges of NGLs or refinery-grade propylene simultaneously at rates up to 5,000 barrels per hour. We also own an NGL terminal in Providence, Rhode Island that includes 0.4 MMBbls of refrigerated tank storage capacity and ship unloading capabilities at rates of up to 11,800 barrels per hour. Our average combined NGL import and export volumes were 103 MBPD, 114 MBPD and 98 MBPD for the years ended December 31, 2011, 2010 and 2009, respectively.

In March 2011, we announced an expansion of our primary Houston Ship Channel import/export terminal. This expansion project is expected to nearly double the terminal’s fully refrigerated export loading capacity for propane and other NGLs to more than 10,000 barrels per hour, while also enhancing the terminal’s ability to load multiple vessels simultaneously. We expect to complete this project in the second half of 2012.

Onshore Natural Gas Pipelines & Services

Our Onshore Natural Gas Pipelines & Services business segment includes approximately 20,200 miles of onshore natural gas pipeline systems that provide for the gathering and transportation of natural gas in Colorado, Louisiana, New Mexico, Texas and Wyoming. We lease salt dome natural gas storage facilities located in Texas and Louisiana and own a salt dome storage cavern in Texas that are integral to our pipeline operations. This segment also includes our related natural gas marketing activities.

Onshore natural gas pipelines and related natural gas storage and marketing activities . Our onshore natural gas pipeline systems and storage facilities provide for the gathering and transportation of natural gas from major producing regions such as the San Juan, Barnett Shale, Permian, Piceance, Greater Green River, Haynesville Shale and Eagle Ford Shale supply basins in the western U.S. In addition, certain of these systems receive natural gas production from the Gulf of Mexico through coastal pipeline interconnects with offshore pipelines. Our onshore natural gas pipelines receive natural gas from producers, other pipelines or shippers at the wellhead or through system interconnects and redeliver the natural gas to processing facilities, local gas distribution companies, industrial or municipal customers, storage facilities or to other onshore pipelines.

reserved in our pipelines whether or not the shipper actually utilizes such capacity. Under our natural gas storage contracts, there are typically two components of revenues: (i) monthly demand payments, which are associated with a customer’s storage capacity reservation and paid regardless of actual usage, and (ii) storage fees per unit of volume stored at our facilities. In connection with our natural gas transportation services and marketing activities, intrastate natural gas pipelines (such as our Acadian Gas System) may also purchase natural gas from producers and other suppliers for transport and resale to customers such as electric utility companies, local natural gas distribution companies, industrial users and other natural gas marketing companies.

Our natural gas marketing activities generate revenues from the sale and delivery of natural gas obtained from third party well-head purchases, regional natural gas processing plants and the open market. In general, sales prices referenced in the contracts utilized within our natural gas marketing activities are market-based and may include pricing differentials for such factors as delivery location. The results of operations for our onshore natural gas pipelines and related storage and marketing activities are generally dependent upon the volume of natural gas transported, stored and/or sold, the level of firm capacity reservations made by customers and amounts charged to customers (including those charged internally, which are eliminated in the preparation of our Consolidated Financial Statements).

We are exposed to commodity price risk to the extent that we take title to natural gas volumes in connection with certain intrastate natural gas transportation contracts and our natural gas marketing activities. In addition, we purchase and resell natural gas for certain producers that use our San Juan, Carlsbad and Jonah Gathering Systems and certain segments of our Texas Intrastate System. Also, several of our gathering systems, while not providing marketing services, have some exposure to risks related to fluctuations in commodity prices through transportation arrangements with shippers. For example, nearly all of the transportation revenues generated by our San Juan Gathering System are based on a percentage of a regional price index for natural gas. This index is subject to change based on a variety of factors including natural gas supply and consumer demand. We use derivative instruments to mitigate our exposure to commodity price risks associated with our natural gas pipelines and services business.

Seasonality . Typically, our onshore natural gas pipelines experience higher throughput rates during the summer months as natural gas-fired power generation utilities increase their output to meet residential and commercial demand for electricity used for air conditioning. Higher throughput rates are also experienced in the winter months as natural gas is used to meet residential and commercial heating requirements. Our facilities located along the Gulf Coast of the U.S. may be affected by weather events such as hurricanes and tropical storms, which generally arise during the summer and fall months.

Competition . Within their market areas, our onshore natural gas pipelines compete with other natural gas pipelines on the basis of price (in terms of transportation fees), quality of customer service and operational flexibility. Our natural gas marketing activities compete primarily with other natural gas pipeline companies and their marketing affiliates and financial institutions with trading platforms. Competition in the natural gas marketing business is based primarily on quality of customer service, competitive pricing and proximity to customers and market hubs.

The remainder of our Texas Intrastate System is wholly owned. (2) The Acadian Gas System is wholly owned except for the 27-mile Evangeline pipeline and a 1.3 Bcf storage facility we hold under an operating lease that expires in December 2012. Our ownership interest in the Evangeline pipeline is held indirectly through our aggregate 49.5% equity method investment in Evangeline Gas Pipeline Company, L.P. and Evangeline Gas Corp (collectively “Evangeline”). (3) In 2011, we completed the integration of the Val Verde Gas Gathering System we acquired in the TEPPCO Merger into our legacy San Juan Gathering System. The combined natural gas gathering system retained the San Juan Gathering System name. (4) Our ownership interest in the White River Hub facility is held indirectly through our equity method investment in White River Hub, LLC (“White River Hub”). (5) Our Haynesville Gathering Systems consist of the State Line gathering system that we acquired in May 2010 and the South East Mansfield gathering system and South East Stanley gathering system that we constructed and placed into service during 2010 and 2011, respectively. (6) We acquired the Fairplay Gathering System in May 2010. (7) We proportionately consolidate our undivided interest in the Indian Springs Gathering System.

In December 2011, we sold our natural gas storage facilities in Petal and Hattiesburg, Mississippi that were owned by Crystal Holding L.L.C. (“Crystal”) for $550.0 million in cash, before working capital adjustments. For more information regarding the sale of our Mississippi natural gas storage facilities, see “Significant Recent Developments—Sale of Our Mississippi Natural Gas Storage Facilities” included under Item 7 of this annual report. In August 2011, we sold our Alabama Intrastate System for $21.8 million in cash, before working capital adjustments. The Alabama system was not integrated with our other midstream energy assets.

On a weighted-average basis, aggregate utilization rates for our onshore natural gas pipelines were approximately 64.6%, 64.2% and 64.4% during the years ended December 31, 2011, 2010 and 2009, respectively. Such utilization rates represent actual natural gas volumes delivered as a percentage of our nominal delivery capacity and do not reflect firm capacity reservation agreements where throughput capacity is reserved whether or not the shipper actually utilizes such capacity. Our utilization rates reflect the periods in which we owned an interest in such assets or, for recently constructed assets, since the dates such assets were placed into service.

The following information highlights the general use of each of our principal onshore natural gas pipelines. With the exception of the White River Hub and certain minor segments of the Texas Intrastate System, we operate our onshore natural gas pipelines and storage facilities.

generation and industrial and municipal consumers as well as to connections with intrastate and interstate pipelines. The Texas Intrastate System is comprised of the 6,917-mile Enterprise Texas pipeline system, the 634-mile Channel pipeline system, the 708-mile Waha gathering system and the 152-mile TPC Offshore gathering system. The Enterprise Texas pipeline system includes a 265-mile pipeline we lease from an affiliate of Energy Transfer Equity, L.P. (“Energy Transfer Equity”). The Wilson natural gas storage facility located in Wharton County, Texas is an integral part of the Texas Intrastate System. Collectively, the Texas Intrastate System serves important natural gas producing regions and commercial markets in Texas, including Corpus Christi, the San Antonio/Austin area, the Beaumont/Orange area and the Houston area, including the Houston Ship Channel industrial market.

The 173-mile Sherman Extension pipeline, which is part of our Enterprise Texas pipeline system, was completed in late February 2009 and is capable of transporting up to 1.2 Bcf/d of natural gas from the Barnett Shale supply basin in North Texas. The Sherman Extension provides producers with connections to third party interstate pipelines having access to markets outside of Texas. An aggregate of 1.0 Bcf/d of the Sherman Extension’s throughput capacity has been contracted for by customers, including EPO, under long-term contracts.

In July 2010, we completed and placed the final segment of our Trinity River Lateral natural gas pipeline into service. The Trinity River Lateral pipeline, which is part of our Enterprise Texas pipeline system, extends approximately 42 miles from the Trinity River Basin north of Arlington, Texas to an interconnect with our Sherman Extension pipeline near Justin, Texas. The Trinity River Lateral provides producers in Tarrant and Denton Counties in North Texas with up to 1.0 Bcf/d of production takeaway capacity.

In April 2011, we completed and placed a fifth storage cavern at the Wilson natural gas storage facility into service. We own and operate this new cavern, which provides us with an additional 6.1 Bcf of usable natural gas storage capacity.

The Acadian Gas System purchases, transports, stores and resells natural gas in Louisiana. The Acadian Gas System is comprised of the 590-mile Cypress pipeline, 442-mile Acadian pipeline, 270-mile Haynesville Extension and 27-mile Evangeline pipeline. The Acadian Gas System includes a leased natural gas storage facility at Napoleonville, Louisiana that is an integral part of its pipeline operations. The Acadian Gas pipeline system links natural gas supplies from onshore Gulf Coast (including the Haynesville Shale supply basin) and offshore Gulf of Mexico developments with local gas distribution companies, electric generation plants and industrial customers, located primarily in the natural gas market area of the Baton Rouge – New Orleans – Mississippi River corridor.

In November 2011, commercial operations on the Haynesville Extension of our Acadian Gas System commenced. As a result of completing the Haynesville Extension project, we have provided producers in Louisiana’s Haynesville and Bossier Shale plays with access to 1.8 Bcf/d of incremental natural gas takeaway capacity. As an extension of our Acadian Gas System, the Haynesville Extension offers producers access to more than 150 end-user customer service locations along the Mississippi River industrial corridor between Baton Rouge and New Orleans, as well as the Henry Hub. The Haynesville Extension features interconnects with twelve interstate pipeline systems and is the only southerly option that avoids potential natural gas supply bottlenecks at the Perryville Hub and offers producers flow assurance and market choice to assist in maximizing the value of their natural gas.

The Jonah Gathering System is located in the Greater Green River Basin of southwest Wyoming. This system gathers natural gas from the Jonah and Pinedale supply fields for delivery to regional natural gas processing plants, including our Pioneer facilities, for ultimate delivery into major interstate pipelines.

The San Juan Gathering System serves producers in the San Juan Basin of northern New Mexico and southern Colorado. This system gathers natural gas from production wells located in the San Juan Basin and delivers the natural gas either directly into major interstate pipelines or to regional processing and treating plants, including our Chaco processing facility and Val Verde treating plant located in New Mexico, for ultimate delivery into major interstate pipelines.

The Piceance Basin Gathering System consists of a network of gathering pipelines located in the Piceance Basin of northwestern Colorado. The Piceance Creek Gathering System gathers natural gas throughout the Piceance Basin to our Meeker natural gas processing complex for ultimate delivery into the White River Hub and other major interstate pipelines.

§	The White River Hub is a regulated interstate natural gas transportation hub facility. The White River Hub connects to six interstate natural gas pipelines in northwest Colorado and has a gross capacity of 3 Bcf/d of natural gas (1.5 Bcf/d net to our 50% ownership interest).

The Haynesville Gathering Systems consist of the 203-mile State Line gathering system, the 56-mile South East Mansfield gathering system and the 36-mile South East Stanley gathering system. Our Haynesville Gathering Systems gather natural gas produced from the Haynesville and Bossier Shale supply basins and the Cotton Valley and Taylor Sand formations in Louisiana and eastern Texas for delivery to several downstream markets including the Haynesville Extension of our Acadian Gas System.

The Fairplay Gathering System gathers natural gas produced from the Haynesville and Bossier Shale supply basins and the Cotton Valley and Taylor Sand formations within Panola and Rusk Counties in East Texas. This system is expected to extend our asset base through potential future interconnects with our Texas Intrastate System, support deliveries of NGLs into our Panola liquids pipeline and further to our fractionation, storage and distribution complex in Mont Belvieu, Texas.

§	The C arlsbad Gathering System gathers natural gas from the Permian Basin region of Texas and New Mexico for delivery to natural gas processing plants, including our Chaparral and Carlsbad plants, as well as delivery into the El Paso Natural Gas and Transwestern pipelines.

Onshore Crude Oil Pipelines & Services

Our Onshore Crude Oil Pipelines & Services business segment includes approximately 5,250 miles of onshore crude oil pipelines and 12 MMBbls of above-ground storage tank capacity. This segment also includes our crude oil marketing activities.

Onshore crude oil pipelines, terminals and related marketing activities . Our onshore crude oil pipeline systems gather and transport crude oil primarily in New Mexico, Oklahoma and Texas to refineries, centralized storage terminals and connecting pipelines. Revenue from crude oil transportation is generally based upon a fixed fee per barrel transported multiplied by the volume delivered. Accordingly, the results of operations for this business are generally dependent upon the volume of crude oil transported and the level of fees charged to customers (including those charged internally, which are eliminated in the preparation of our Consolidated Financial Statements). The transportation fees charged under these arrangements are either contractual or regulated by governmental agencies, including the FERC.

We own crude oil terminal facilities in Cushing, Oklahoma and Midland, Texas that are used to store crude oil volumes for us and our customers. Under our crude oil terminaling agreements, we charge customers for crude oil storage based on the number of days a customer has volumes in storage multiplied by a contractual storage fee. With respect to storage capacity reservation agreements, we collect a fee for reserving storage capacity for customers at our terminals. The customers pay reservation fees based on the level of storage capacity reserved rather than the actual volumes stored. In addition, we charge our customers throughput (or “pumpover”) fees based on volumes withdrawn from our terminals. Lastly, we provide fee-based trade documentation services whereby we document the transfer of title for crude oil volumes transacted between buyers and sellers at our terminals. In general, the profitability of our crude oil terminaling operations is dependent upon the level of storage capacity reserved by our customers, the volume of product withdrawn from our terminals and the level of fees charged (including those charged internally, which are eliminated in the preparation of our Consolidated Financial Statements).

Our crude oil marketing activities generate revenues from the sale and delivery of crude oil obtained from producers or on the open market. In general, the sales prices referenced in these contracts are market-based and may include pricing differentials for such factors as delivery location or crude oil composition. To limit the exposure of

Table of Contents

our crude oil marketing activities to commodity price risk, our purchases and sales of crude oil are generally contracted to occur within the same calendar month. We also use derivative instruments to mitigate our exposure to commodity price risks associated with our crude oil marketing business.

Seasonality . Our onshore crude oil pipelines and related activities typically exhibit little to no effects of seasonality. However, our onshore pipelines situated along the Texas Gulf Coast may be affected by weather events such as hurricanes and tropical storms, which generally arise during the summer and fall months.

Competition . Within their respective market areas, our onshore crude oil pipelines, terminals and related marketing activities compete with other crude oil pipeline companies, major integrated oil companies and their marketing affiliates, financial institutions with trading platforms and independent crude oil gathering and marketing companies. The onshore crude oil business can be characterized by thin operating margins and strong competition for supplies of crude oil. Competition is based primarily on quality of customer service, competitive pricing and proximity to customers and other market hubs.

Properties . The following table summarizes the significant crude oil pipelines and related terminal assets included in our Onshore Crude Oil Pipelines & Services business segment at February 1, 2012:

(1) Our ownership interest in the Seaway Crude Pipeline System is held indirectly through our equity method investment in Seaway Crude Pipeline Company (“Seaway”). Storage capacity presented for Seaway Crude Pipeline System consists of our Jones Creek and Texas City facilities. (2) We proportionately consolidate our undivided interest in the Basin Pipeline System. (3) Includes our Azelea, Mesquite and Sharon Ridge crude oil gathering systems located in Oklahoma and Texas.

The maximum number of barrels that our crude oil pipelines can transport per day depends upon the operating balance achieved at a given point in time between various segments of the systems. Since the operating balance is dependent upon product composition and demand levels at various delivery points, the exact capacities of our crude oil pipelines cannot be reliably determined. We measure the utilization rates of such pipelines in terms of net throughput, which is based on our ownership interest. Total net throughput volumes for these pipelines were 678 MBPD, 670 MBPD and 680 MBPD during the years ended December 31, 2011, 2010 and 2009, respectively.

Our crude oil marketing activities utilize a fleet of approximately 400 tractor-trailer tank trucks, the majority of which are leased from third parties. In addition, we operate 17 crude oil truck terminal facilities in Texas, Oklahoma and North Dakota.

Table of Contents

The following information highlights the general use of each of our principal crude oil pipelines and terminals, all of which we operate with the exception of the Basin Pipeline System.

§	The Seaway Crude Pipeline System is a regulated system that consists of a 503-mile long-haul pipeline connecting markets in Freeport, Texas and Cushing, Oklahoma, 43 miles of gathering and delivery pipelines in Texas and a terminal facility at Texas City, Texas.

§	The Red River System is a regulated pipeline that transports crude oil from North Texas to southern Oklahoma for delivery to either two local refineries or pipeline interconnects for further transportation to Cushing, Oklahoma.

The South Texas Crude Oil Pipeline System transports crude oil originating in South Texas including production from the Eagle Ford Shale supply basin to refineries in the Houston, Texas area. In May 2011, we announced plans to build an 80-mile extension of the South Texas Crude Oil Pipeline System (the “Phase II project”), which would allow us to serve growing production areas in the southwestern portion of the Eagle Ford Shale supply basin. The Phase II project, which is being designed with a crude oil transportation capacity of 200 MBPD, will originate at Lyssy, Texas in Karnes County (at the terminus of our previously announced 140-mile Phase I segment) and extend to Gardendale, Texas in La Salle County, where a new central delivery point is planned for construction that will feature 0.5 MMBbls of crude oil storage. The system’s Phase I pipeline expansion project, which is expected to have a crude oil transportation capacity of 350 MBPD, originates at Sealy, Texas in Austin County and extends to Lyssy, Texas. Phase I of the expansion project includes construction of an aggregate 2.4 MMBbls of crude oil storage capacity along the new pipeline, including 0.6 MMBbls at Lyssy, Texas, 0.2 MMBbls at Milton, Texas, 0.4 MMBbls at Marshall, Texas, and 1.2 MMBbls at Sealy, Texas. Phase I of the project is forecast to begin service by the second quarter of 2012, with Phase II set to commence operations in the first quarter of 2013. For additional information regarding this project, see “Significant Recent Developments—Expansion of Our South Texas Crude Oil Pipeline System” under Item 7 of this annual report.

§	The West Texas System connects crude oil gathering systems in West Texas and southeast New Mexico to our terminal facility in Midland, Texas.

§	The Basin Pipeline System transports crude oil from the Permian Basin in West Texas and southern New Mexico to Cushing, Oklahoma.

The Cushing and Midland terminals provide crude oil storage, pumpover and trade documentation services. Our terminal in Cushing, Oklahoma has 19 above-ground storage tanks with aggregate crude oil storage capacity of 3.1 MMBbls. The Midland terminal has a storage capacity of 1.5 MMBbls through the use of 12 above-ground storage tanks.

We are constructing a new crude oil terminal, our Enterprise Crude Houston (“ECHO”) facility, southeast of Houston in connection with the expansion of our South Texas System and the planned reversal of the Seaway pipeline. The ECHO terminal will provide shippers with access to major refiners located in the Houston and Texas City, Texas refining hub representing more than 2 MMBPD of refining capacity. The ECHO terminal will also have connections to marine facilities which will provide connectivity to any refinery on the U.S. Gulf Coast. The ECHO facility is scheduled to begin service in mid-2012 and will initially have 0.8 MMBbls of crude oil storage capacity.

Table of Contents

We will own and operate the ECHO terminal. In February 2012, we announced an expansion of our ECHO facility, which will provide capability to increase its crude oil storage capacity to approximately 6 MMBbls.

Seaway plans to build a 45-mile pipeline that will link its pipeline to our ECHO terminal. Completion of this pipeline segment is expected in the first quarter of 2013. In addition, Seaway plans to build an 85-mile pipeline from our ECHO facility to the Port Arthur/Beaumont, Texas refining center that would provide shippers access to the region’s heavy oil refining capabilities. Completion of this pipeline segment is expected in early 2014.

Offshore Pipelines & Services

Our Offshore Pipelines & Services business segment serves some of the most active drilling and development regions, including deepwater production fields, in the northern Gulf of Mexico offshore Texas, Louisiana, Mississippi and Alabama. This segment includes approximately 1,330 miles of offshore natural gas pipelines, approximately 980 miles of offshore crude oil pipelines and six offshore hub platforms.

Our offshore Gulf of Mexico pipelines provide for the gathering and transportation of natural gas or crude oil. In general, revenue from our offshore pipelines is derived from fee-based agreements whereby the customer is charged a fee per unit of volume gathered or transported (typically per MMBtu of natural gas or per barrel of crude oil) multiplied by the volume delivered. These agreements tend to be long-term, often involving life-of-reserve commitments with both firm and interruptible components.

Poseidon Oil Pipeline Company, L.L.C. (“Poseidon”), in which we have a 36% equity method investment, purchases crude oil from producers and shippers at a receipt point (at a fixed or index-based price less a location differential) and then sells like quantities of crude oil at onshore Louisiana locations (at the same fixed or index-based price, as applicable). When these transactions are completed with the same counterparty, Poseidon recognizes net revenues from such arrangements based on the location differential, which represents the fee charged for providing transportation services on the Poseidon Oil Pipeline System. If Poseidon purchases and sells like crude oil volumes with different counterparties, Poseidon recognizes revenues based on the crude oil sales price multiplied by the volume sold.

Our offshore platforms are integral components of our pipeline operations. In general, platforms are critical components of the energy-related infrastructure in the Gulf of Mexico, supporting drilling and producing operations, and therefore play a key role in the overall development of offshore crude oil and natural gas reserves. Platforms are used to: interconnect the offshore pipeline network; provide an efficient means to perform pipeline maintenance; locate compression, separation and production handling equipment and similar assets; and conduct drilling operations during the initial development phase of an oil and natural gas property. Revenues from offshore platform services generally consist of demand fees and commodity charges. Demand fees are similar to firm capacity reservation agreements for a pipeline in that they are charged to a customer regardless of the volume the customer actually delivers to the platform. Revenue from commodity charges is based on a fixed-fee per unit of volume delivered to the platform (typically per MMcf of natural gas or per barrel of crude oil) multiplied by the total volume of each product delivered. Contracts for platform services often include both demand fees and commodity charges, but demand fees generally expire after a contractually fixed period of time and in some instances may be subject to cancellation by customers. For example, the producers connected to our Independence Hub platform paid us approximately $54.6 million of demand fees annually from March 2007 through February 2012. These demand fees are in addition to commodity charges they pay us based on volumes delivered to the platform.

In April 2010, in an event unrelated to Enterprise’s operations, the Deepwater Horizon drilling rig caught fire and sank in the Gulf of Mexico, resulting in an oil spill. As a result, governmental agencies took actions to halt most drilling operations in the Gulf of Mexico for a period of time extending into October 2010. The moratorium has impacted the timing of exploration and production activities in the Gulf of Mexico. For additional information regarding the Deepwater Horizon incident and its effects on Gulf of Mexico exploration and production activities, see “—Additional regulations that cause delays or deter new offshore oil and gas drilling could have a material adverse effect on our financial position, results of operations and cash flows” on page 55 under Item 1A of this annual report.

Table of Contents

Seasonality . Our offshore operations exhibit little to no effects of seasonality; however, they may be affected by weather events such as hurricanes and tropical storms in the Gulf of Mexico that generally arise during the summer and fall months. See Note 19 of the Notes to Consolidated Financial Statements included under Item 8 of this annual report for information regarding weather-related risks and insurance matters.

Competition . Within their respective market areas, our offshore pipelines compete with other offshore pipelines primarily on the basis of fees charged, available throughput capacity, connections to downstream markets and proximity and access to existing reserves. Our competitors may have access to greater capital resources than we do, which could enable them to address business opportunities in the Gulf of Mexico more quickly than we can.

Petrochemical & Refined Products Services

Our Petrochemical & Refined Products Services business segment consists of (i) propylene fractionation plants, pipelines and related marketing activities; (ii) a butane isomerization facility and related pipeline system; (iii) octane enhancement and high purity isobutylene production facilities; (iv) refined products pipelines, including our Products Pipeline System (as defined below), and related marketing activities; and (v) marine transportation and other services.

Propylene fractionation and related activities . Our propylene fractionation and related activities primarily consist of seven propylene fractionation plants (six located in Mont Belvieu, Texas and a seventh in Baton Rouge, Louisiana), propylene pipeline systems aggregating approximately 680 miles in length and related petrochemical marketing activities. This business includes an export facility and associated above-ground polymer grade propylene storage spheres located in Seabrook, Texas.

In general, propylene fractionation plants separate refinery grade propylene, which is a mixture of propane and propylene, into either polymer grade propylene or chemical grade propylene along with by-products of propane and mixed butane. Polymer grade and chemical grade propylene can also be produced as a by-product of ethylene production. The demand for polymer grade propylene primarily relates to the manufacture of polypropylene, which has a variety of end uses including packaging film, fiber for carpets and upholstery and molded plastic parts for appliances and automotive, houseware and medical products. Chemical grade propylene is a basic petrochemical used in the manufacturing of plastics, synthetic fibers and foams.

Results of operations for our polymer grade propylene plants are generally dependent upon toll processing arrangements and petrochemical marketing activities. The toll processing arrangements typically include a base-processing fee per gallon (or other unit of measurement) subject to adjustment for changes in natural gas, electricity and labor costs, which are the primary costs of propylene fractionation. Our petrochemical marketing activities include the purchase and fractionation of refinery grade propylene obtained in the open market and generate revenues from the sale and delivery of products obtained through propylene fractionation. In general, we sell our petrochemical products at market-based prices, which may include pricing differentials for such factors as delivery location. The majority of revenues from our propylene pipelines are based upon a transportation fee per unit of volume multiplied by the volume delivered to the customer. Propylene transportation agreements may include deficiency fee provisions whereby the customer pays us a fee if certain volume thresholds are not met over a contractual term.

As part of our petrochemical marketing activities, we have several long-term refinery grade propylene purchase and polymer grade propylene sales agreements. To limit the exposure of our petrochemical marketing activities to commodity price risk, we attempt to match the timing and price of our feedstock purchases with those of the sales of end products.

Butane isomerization . Our butane isomerization business includes three butamer reactor units and eight associated deisobutanizer units located in Mont Belvieu, Texas, which comprise the largest commercial

Table of Contents

isomerization facility in the U.S. In addition, this business includes a 70-mile pipeline system used to transport high-purity isobutane from Mont Belvieu, Texas to Port Neches, Texas.

Our commercial isomerization units convert normal butane into mixed butane, which is subsequently fractionated into isobutane, high-purity isobutane and residual normal butane. The primary uses of isobutane are for the production of propylene oxide, isooctane, isobutylene and alkylate for motor gasoline. The demand for commercial isomerization services depends upon the industry’s requirements for isobutane and high-purity isobutane in excess of the isobutane produced through the process of NGL fractionation and refinery operations.

The results of operation of this business are generally dependent upon the volume of normal and mixed butanes processed and the level of toll processing fees charged to customers. These processing arrangements typically include a base-processing fee per gallon (or other unit of measurement) subject to adjustment for changes in natural gas, electricity and labor costs, which are the primary costs of isomerization. Our isomerization facility provides processing services to meet the needs of third party customers and our other businesses, including our NGL marketing activities and octane enhancement production facility. Our isomerization business also generates revenues from the sale of natural gasoline created as a by-product of the isomerization process.

Octane enhancement and high purity isobutylene . We own and operate an octane enhancement production facility located in Mont Belvieu, Texas that is designed to produce isooctane, isobutylene and methyl tertiary butyl ether (“MTBE”). The products produced by this facility are used in reformulated motor gasoline blends to increase octane values. The high-purity isobutane feedstocks consumed in the production of these products are supplied by our isomerization units. To the extent that MTBE is produced at our Mont Belvieu facility, it is strictly sold into the export market.

The results of operations of this business are generally dependent upon the sale and delivery of products produced. In general, we sell our octane enhancement products at market-based prices, which may include pricing differentials for such factors as delivery location. We attempt to mitigate price risk by entering into certain commodity hedging transactions.

We own a facility located on the Houston Ship Channel that produces high purity isobutylene (“HPIB”). The primary feedstock for this plant is produced by our octane enhancement facility located at our Mont Belvieu complex. HPIB is used in the production of alkylated phenols used as antioxidants, lube oil additives, butyl rubber and resins. The results of operations of this business are generally dependent upon the sale and delivery of products produced. In general, we sell HPIB at market-based prices, which may include pricing differentials for such factors as delivery location.

Refined products pipelines and related activities . Refined products pipelines and related activities primarily consist of our (i) Products Pipeline System, (ii) equity method investment in Centennial Pipeline LLC (“Centennial”) and (iii) refined products marketing activities. Our Products Pipeline System consists of (i) a regulated 4,313-mile interstate pipeline system that generally extends in a northeasterly direction from the upper Texas Gulf Coast to the northeast U.S., (ii) 326 miles of intrastate pipelines in Texas and (iii) related terminal operations.

The Products Pipeline System transports refined products, and to a lesser extent, petrochemicals such as ethylene and propylene and NGLs such as propane and normal butane. These refined products are produced by refineries and include gasoline, diesel fuel, aviation fuel, kerosene, distillates and heating oil. Refined products also include blend stocks such as raffinate and naphtha. Blend stocks are primarily used to produce gasoline or as a feedstock for certain petrochemicals. The Centennial Pipeline intersects our Products Pipeline System near Creal Springs, Illinois, and effectively loops the Products Pipeline System between Beaumont, Texas and south Illinois. Looping the Products Pipeline System permits effective supply of products to points south of Illinois as well as incremental product supply capacity to other Midcontinent markets.

Our refined products pipelines and related activities include six refined products truck terminals and 13 storage terminals located along the Products Pipeline System. In addition, we have refined products terminals located at Aberdeen, Mississippi and Boligee, Alabama adjacent to the Tombigbee River and on the Houston Ship Channel in Pasadena, Texas.

Table of Contents

The results of operations of our refined products pipelines are primarily dependent on the tariffs charged to customers to transport products and the volume delivered. The tariffs charged for such services are either contractual or regulated by governmental agencies, including the FERC. The results of our storage and terminal assets are primarily dependent on the volume and associated fees charged to customers (including those charged internally, which are eliminated in the preparation of our Consolidated Financial Statements). Our related marketing activities generate revenues from the sale and delivery of refined products obtained from third parties on the open market. In general, we sell our refined products at market-based prices, which may include pricing differentials for such factors as delivery location. Our refined products marketing sales contracts may also include forward product sales contracts.

Marine transportation and other services . Our marine transportation business consists of tow boats and tank barges that are primarily used to transport refined products, crude oil, asphalt, condensate, heavy fuel oil, liquefied petroleum gas and other petroleum products along key inland and intracoastal U.S. waterways. Our marine transportation assets service refinery and storage terminal customers along the Mississippi River, the intracoastal waterway between Texas and Florida and the Tennessee-Tombigbee Waterway system. We own a shipyard and repair facility located in Houma, Louisiana and marine fleeting facilities in Bourg, Louisiana and Channelview, Texas.

The results of operations of our marine transportation business are generally dependent upon the level of fees charged to transport cargo. These transportation services are typically provided under term contracts (also referred to as affreightment contracts), which are agreements with specific customers to transport cargo from within designated operating areas at set day rates or a set fee per cargo movement.

Other services consist of the distribution of lubrication oils and specialty chemicals and the bulk transportation of fuels by truck, principally in Oklahoma, Texas, New Mexico, Kansas and the Rocky Mountain region of the U.S. In addition, our wholly owned subsidiary, Enterprise Products Transportation Company LLC (“ETC”), utilizes a fleet of approximately 775 tractor-trailer tank trucks to transport NGLs and petrochemicals. ETC’s fleet is supported by 26 truck terminals that we operate in various locations throughout the U.S.

The results of operations from other non-marine services are dependent on the sales price or transportation fees that we charge our customers and the volume sold or transported.

Seasonality . Overall, the propylene fractionation business exhibits little seasonality. Our isomerization operations experience slightly higher levels of demand in the spring and summer months due to increased demand for isobutane-based fuel additives used in the production of motor gasoline. Likewise, octane additive prices have been stronger during the April to September period of each year, which corresponds with the summer driving season, when motor gasoline demand increases.

Our refined products pipelines and related activities exhibit seasonality based upon the mix of products delivered and the weather and economic conditions in the geographic areas being served. Refined products volumes are generally higher during the second and third quarters of each year because of greater demand for motor gasoline during the spring and summer driving seasons. NGL transportation volumes on the Products Pipeline System are generally higher from October through March due to higher demand for propane (for residential heating) and normal butane (for blending in motor gasoline).

Our marine transportation business exhibits some seasonal variation. Demand for motor gasoline and asphalt is generally stronger in the spring and summer months due to the summer driving season and when weather allows for more efficient road construction. Weather events, such as hurricanes and tropical storms in the Gulf of Mexico, can adversely impact both the offshore and inland businesses. Generally during the winter months, cold weather and ice can negatively impact the inland operations on the upper Mississippi and Illinois rivers.

Competition . We compete with numerous producers of polymer grade propylene, which include many of the major refiners and petrochemical companies located along the Gulf Coast. Generally, our propylene fractionation business competes in terms of the level of toll processing fees charged and access to pipeline and storage infrastructure. Our petrochemical marketing activities encounter competition from fully integrated oil companies and various petrochemical companies. Our petrochemical marketing competitors have varying levels of

Table of Contents

financial and personnel resources and competition generally revolves around price, quality of customer service, logistics and location.

With respect to our isomerization operations, we compete primarily with facilities located in Kansas, Louisiana and New Mexico. Competitive factors affecting this business include the level of toll processing fees charged, the quality of isobutane that can be produced and access to pipeline and storage supporting infrastructure. We compete with other octane additive manufacturing companies primarily on the basis of price.

The Products Pipeline System’s most significant competitors are third party pipelines in the areas where it delivers products. Competition among common carrier pipelines is based primarily on transportation fees, quality of customer service and proximity to end users. Trucks, barges and railroads competitively deliver products into some of the areas served by our Products Pipeline System and river terminals. The Products Pipeline System faces competition from rail and pipeline movements of NGLs from Canada and waterborne imports into terminals located along the upper East Coast.

Our marine transportation business competes with other inland marine transportation companies as well as providers of other modes of transportation, such as rail tank cars, tractor-trailer tank trucks and, to a limited extent, pipelines. Competition within the marine transportation business is largely based on price.

(7) We acquired our HPIB facility located on the Houston Ship Channel in November 2010. On a weighted average basis, utilization rates for our HPIB facility were 31.5% during the year ended December 31, 2011.

We produce polymer grade propylene at our Mont Belvieu, Texas propylene fractionation facility and chemical grade propylene at our BRPC facility located in Baton Rouge, Louisiana. The primary purpose of the BRPC unit is to fractionate refinery grade propylene produced by an affiliate of Exxon Mobil Corporation into chemical grade propylene. The polymer grade propylene produced by our Mont Belvieu facility is primarily for the benefit of our tolling customers and used in our petrochemical marketing activities to service long-term third party contracts. On a weighted-average basis, aggregate utilization rates of our propylene fractionation facilities were approximately 90.2%, 95.3% and 85% during the years ended December 31, 2011, 2010 and 2009, respectively. As noted previously, this business includes an export facility and above-ground polymer grade propylene storage spheres.

The Lou-Tex Propylene pipeline is used to transport chemical grade propylene from Sorrento, Louisiana to Mont Belvieu, Texas. The Sabine pipeline is used to transport polymer grade propylene from Port Arthur, Texas to a third party pipeline interconnect located in Cameron Parish, Louisiana. The North Dean Pipeline System transports refinery grade propylene from Mont Belvieu, Texas, to Point Comfort, Texas. The Port Neches Pipeline transports high purity isobutane between Mont Belvieu, Texas and Port Neches, Texas. The remainder of our

Table of Contents

petrochemical pipelines primarily transport refinery grade propylene or polymer grade propylene for customers in southeast Texas and southwest Louisiana.

The maximum number of barrels that our petrochemical pipelines can transport per day depends upon the operating balance achieved at a given point in time between various segments of the systems. Since the operating balance is dependent upon the mix of products to be shipped and demand levels at various delivery points, the exact capacities of our petrochemical pipelines cannot be reliably determined. We measure the utilization rates of such pipelines in terms of net throughput, which is based on our ownership interest. Total net throughput volumes for these pipelines were 117 MBPD, 135 MBPD and 124 MBPD during the years ended December 31, 2011, 2010 and 2009, respectively.

The following table summarizes the significant refined products pipelines and related terminal and storage assets included in our Petrochemical & Refined Products Services business segment at February 1, 2012:

In January 2012, we announced the development of our ATEX Express long-haul ethane pipeline. This project would utilize a combination of new and existing infrastructure. The southern portion of ATEX Express would utilize a significant portion of our existing Products Pipeline System, which would be reversed to accommodate southbound delivery of ethane to the U.S. Gulf Coast. We expect that the ATEX Express will begin commercial operations in the first quarter of 2014.

The Centennial Pipeline is a regulated refined products pipeline system that extends from Texas to Illinois. The Centennial Pipeline extends from an origination facility located on our Products Pipeline System in Beaumont, Texas, to Bourbon, Illinois. Centennial owns a refined products storage terminal located near Creal Springs, Illinois with a gross storage capacity of 2.3 MMBbls.

The following table summarizes the significant marine transportation assets included in our Petrochemical & Refined Products Services business segment at February 1, 2012:

Energy Transfer Equity electronically files reports with the U.S. Securities and Exchange Commission (“SEC”) , including annual reports on Form 10-K and quarterly reports on Form 10-Q.

At December 31, 2011, we owned 29,303,514 limited partner common units of Energy Transfer Equity. Our limited partner interests in Energy Transfer Equity were originally acquired by Holdings in May 2007. Equity investments are part of our business strategy; however, we may from time-to-time elect to divest all or a portion of

Table of Contents

our equity investments in order to redeploy capital. During 2011, we sold a total of 9,672,576 Energy Transfer Equity common units for net cash proceeds of $375.2 million and recorded aggregate gains of $27.2 million on such sales.

In January 2012, we sold 22,762,636 million common units of Energy Transfer Equity in a private transaction, which generated cash proceeds of approximately $825.1 million. Proceeds from this sale were used for general company purposes, including funding capital expenditures. As of the date of this report, we own approximately 6 million common units of Energy Transfer Equity, which represent less than 3% of its common units outstanding at February 15, 2012.

Title to Properties

Our real property holdings fall into two basic categories: (i) parcels that we and our unconsolidated affiliates own in fee (e.g., we own the land upon which our Mont Belvieu NGL fractionators are constructed) and (ii) parcels in which our interests and those of our affiliates are derived from leases, easements, rights-of-way, permits or licenses from landowners or governmental authorities permitting the use of such land for our operations. The fee sites upon which our significant facilities are located have been owned by us or our predecessors in title for many years without any material challenge known to us relating to title to the land upon which the assets are located, and we believe that we have satisfactory title to such fee sites. We and our affiliates have no knowledge of any challenge to the underlying fee title of any material lease, easement, right-of-way, permit or license held by us or to our rights pursuant to any material lease, easement, right-of-way, permit or license, and we believe that we have satisfactory rights pursuant to all of our material leases, easements, rights-of-way, permits and licenses.

Regulation

The following sections describe the general impact of regulation on our business. Additional information regarding regulatory risks are described under Item 1A of this annual report.

Interstate Pipelines

Liquids Pipelines . Certain of our refined products, crude oil and NGL pipeline systems (collectively referred to as “liquids pipelines”) are interstate common carrier pipelines subject to regulation by the FERC under the Interstate Commerce Act (“ICA”) and the Energy Policy Act of 1992 (“Energy Policy Act”). The ICA prescribes that interstate tariffs must be just and reasonable and must not be unduly discriminatory or confer any undue preference upon any shipper. FERC regulations require that interstate oil pipeline transportation rates and terms of service be filed with the FERC and posted publicly.

The ICA permits interested persons to challenge proposed new or changed rates or rules and authorizes the FERC to investigate such changes and to suspend their effectiveness for a period of up to seven months. If, upon completion of an investigation, the FERC finds that the new or changed rate is unlawful, it may require the carrier to refund the revenues together with interest in excess of the prior tariff during the term of the investigation. The FERC may also investigate, upon complaint or on its own motion, rates and related rules that are already in effect and may order a carrier to change them prospectively. Upon an appropriate showing, a shipper may obtain reparations for damages sustained for a period of up to two years prior to the filing of its complaint.

The Energy Policy Act deems just and reasonable (i.e., deems “grandfathered”) liquids pipeline rates that (i) were in effect for the 12 months preceding enactment and (ii) that had not been subject to complaint, protest or investigation. Some, but not all, of our interstate liquids pipeline rates are considered grandfathered under the Energy Policy Act. Certain other rates for our interstate liquids pipeline services are charged pursuant to a FERC-approved indexing methodology, which allows a pipeline to charge rates up to a prescribed ceiling that changes annually based on the change from year-to-year in the Producer Price Index for finished goods (“PPI”). A rate increase within the indexed rate ceiling is presumed to be just and reasonable unless a protesting party can demonstrate that the rate increase is substantially in excess of the pipeline’s costs. During the five-year period commencing July 1, 2006 and ending June 30, 2011, liquids pipelines charging indexed rates were permitted to adjust their indexed ceilings annually by the PPI plus 1.3%. During the five-year period commencing July 1, 2011

Table of Contents

and ending June 30, 2016, liquids pipelines charging indexed rates are permitted to adjust their indexed ceilings annually by the PPI plus 2.65%.

As an alternative to using the indexing methodology, interstate liquids pipelines may elect to support rate filings by using a cost-of-service methodology, competitive market showings (“Market-Based Rates”) or agreements with all of the pipeline’s shippers that the rate is acceptable. Our Products Pipeline System has been granted permission by the FERC to utilize Market-Based Rates for all of its refined products movements other than movements to the Little Rock, Arkansas; Jonesboro, Arkansas; and Arcadia, Louisiana destination markets, which are currently subject to the PPI. However, as discussed below, movements to these three destination markets are the subject of a pending market-based rate application filed by Enterprise TE Products Pipeline Company LLC (“Enterprise TEPPCO”), an indirect wholly owned subsidiary of EPO.

Due to the complexity of ratemaking, the lawfulness of any rate is never assured. Prescribed rate methodologies for approving regulated tariff rates may limit our ability to set rates based on our actual costs or may delay the use of rates reflecting higher costs. Changes in the FERC’s methodology for approving rates could adversely affect us. In addition, challenges to our tariff rates could be filed with the FERC and decisions by the FERC in approving our regulated rates could adversely affect our cash flow. We believe the transportation rates currently charged by our interstate common carrier liquids pipelines are in accordance with the ICA. However, we cannot predict the rates we will be allowed to charge in the future for transportation services by such pipelines.

In October 2009, the FERC approved an uncontested settlement related to a Mid-America Pipeline Company, LLC (“Mid-America”) and Seminole rate case before the FERC. The case primarily involved shipper protests of rate increases on Mid-America’s Conway North pipeline in FERC Docket Nos. IS05-216-000, IS06-238-000 and IS09-364-000, and challenges to Seminole’s interstate rates and certain joint rates between the Seminole Pipeline and Mid-America’s Rocky Mountain pipeline in FERC Docket Nos. OR06-5-000 and IS06-520-000. The settlement agreement resolved all matters involving Mid-America’s Conway North pipeline at issue in Docket Nos. IS05-216-000, IS06-238-000 and IS09-364-000. Pursuant to the settlement agreement, Mid-America filed new rates for certain propane movements on its Conway North pipeline, which took effect January 1, 2010. Mid-America also paid refunds to propane shippers, as provided by the settlement agreement. In March 2010, Mid-America filed a refund report with the FERC describing the refunds paid. The FERC accepted the refund report in July 2010.

The settlement agreement did not cover the challenges to the Seminole Pipeline and Mid-America Rocky Mountain pipeline rates at issue in Docket Nos. OR06-5-000 and IS06-520-000. In February 2010, the FERC ruled on those issues. The FERC’s order also clarified that Mid-America’s capacity allocation provisions were not subject to challenge in the case but that the changes to Mid-America’s rates contained in FERC Tariff No. 45 were properly at issue. In March 2010, Mid-America and Seminole filed a compliance filing calculating rates consistent with the FERC’s February 2010 order. Two parties protested the revised rates. The FERC has not ruled on those protests and we are unable to predict the outcome of that proceeding.

In April 2010, Enterprise TEPPCO filed tariffs in FERC Docket No. IS10-203-000, making certain revisions to its propane inventory policy. A protest was filed by a group of propane shippers (the “Propane Group”). Various other parties later intervened. On May 13, 2010, the FERC accepted Enterprise TEPPCO’s tariff subject to the condition that the pipeline submit its prorationing and propane inventory policies to the FERC for review. On May 19, 2010, Enterprise TEPPCO submitted its policies to the FERC as requested. In June 2010, the Propane Group and Texas Liquids Partners, LLC sought rehearing of the FERC’s order accepting the tariff. In October 2010, the FERC ruled on the rehearing request and established a hearing to determine whether the propane inventory policy is just and reasonable. In October 2011, the FERC approved a settlement agreement that resolves all matters at issue. Pursuant to the settlement agreement, Enterprise TEPPCO filed a tariff containing a new propane inventory policy, which took effect January 1, 2012. Pursuant to the settlement agreement, Enterprise TEPPCO also calculated certain credits to shippers to offset certain future excess inventory penalties, and certified those calculations to the FERC. Upon certification of the calculations to the FERC, the protests were withdrawn and the proceeding terminated.

In March 2011, Enterprise TEPPCO filed an application in FERC Docket No. OR11-6-000, seeking authorization to charge market-based rates for the interstate transportation of refined petroleum products to the following three delivery locations: Arcadia, Louisiana; Little Rock, Arkansas; and Jonesboro, Arkansas. Protests

Table of Contents

were filed in April 2011 by Lion Oil Company and Chevron Products Company. In October 2011, the FERC set Enterprise TEPPCO’s application for hearing before an administrative law judge (“ALJ”). Under the current procedural schedule, the hearing is set to begin August 1, 2012, and the ALJ’s decision is due December 21, 2012. We are unable to predict the outcome of that proceeding.

In September 2011, Mid-America filed a tariff in FERC Docket No. IS11-604-000, establishing new rates for interstate transportation on a pipeline segment that moves refined petroleum products from Coffeyville, Kansas to El Dorado, Kansas. Coffeyville Resources Refining & Marketing, LLC protested the rate filing. In October 2011, FERC accepted the tariff subject to refund and hearing. The FERC held the hearing in abeyance pending required settlement judge procedures and settlement discussions are ongoing. In December 2011, Mid-America filed a tariff change in FERC Docket No. IS12-97-000, requiring shippers on the Coffeyville to El Dorado pipeline segment to provide certain information necessary to determine whether shippers’ movements are in interstate or intrastate commerce. In January 2012, Coffeyville Resources Refining & Marketing, LLC protested the tariff filing. In January 2012, the FERC accepted the tariff change in FERC Docket No. IS12-97-000, subject to certain modifications. As noted below, Mid-America is also involved in an ongoing matter before the Kansas Corporation Commission (Docket No. 12-MDAP-068-RTS), concerning Mid-America’s intrastate rates for certain movements within the state of Kansas, including the intrastate rate for movements on the Coffeyville to El Dorado pipeline segment. We are unable to predict the outcome of these proceedings.

In December 2011, we and Enbridge Inc., which together own the Seaway Crude Pipeline System, filed an application in FERC Docket No. OR12-4-000, seeking authority to charge market-based rates in connection with the planned reversal of the system. Specifically, the application seeks authority to charge market-based rates for the transportation of crude oil at both its proposed Cushing, Oklahoma origin and Gulf Coast area destination markets after the pipeline reverses its current south-to-north direction of service. Protests have been filed by several parties. We are unable to predict the outcome of this proceeding.

In December 2011, Skelly-Belvieu filed a petition for declaratory order in FERC Docket No. OR12-6-000 seeking FERC approval for the overall tariff, rate and priority service structure for a proposed expansion of its existing pipeline system. The only intervenor filed comments in support of the petition for declaratory order. We are unable to predict the outcome of this proceeding.

In December 2011, Dixie Pipeline Company (which changed its name on December 31, 2011, to Dixie Pipeline Company LLC) filed a tariff in FERC Docket No. IS12-88-000 making certain changes to its prorationing rules. Dow Hydrocarbons and Resources LLC protested the tariff filing, and in January 2012, FERC suspended the tariff for the statutory maximum seven months subject to a technical conference. We are unable to predict the outcome of this proceeding.

In January 2012, Dixie Pipeline Company LLC (“Dixie”) filed a tariff in FERC Docket No. IS12-120 indicating that as of January 1, 2013, propane shippers will no longer be permitted to inject propane into refinery grade propylene batches as the refinery grade propylene moves by the propane shippers’ origin points. Instead, propane shippers will be required to store propane during those periods and make their own arrangements for such storage. Protests were filed by CITGO Petroleum Corporation, Targa Midstream Services LLC, Crosstex Energy Services, L.P., Crosstex NGL Marketing, L.P., and Crosstex Processing Services, LLC. ConocoPhillips Company and Dow Hydrocarbons and Resources LLC moved to intervene. On February 10, 2012, the FERC rejected Dixie’s tariff as premature, since the proposed change was not intended to take effect until January 1, 2013.

In February 2012, Enterprise TEPPCO filed a tariff in FERC Docket No. IS12-160-000, establishing new cost-of-service rates for refined petroleum products and NGL movements. As of this report, the deadline for interventions and protests has not yet expired. We are unable to predict the outcome of this proceeding.

The Lou-Tex and Sabine Propylene pipelines are interstate common carrier pipelines regulated under the ICA by the Surface Transportation Board (“STB”). If the STB finds that a carrier’s rates are not just and reasonable or are unduly discriminatory or preferential, it may prescribe a reasonable rate. In determining a reasonable rate, the STB will consider, among other factors, the effect of the rate on the volumes transported by that carrier, the carrier’s revenue needs and the availability of other economic transportation alternatives.

Table of Contents

The STB does not need to provide rate relief unless shippers lack effective competitive alternatives. If the STB determines that effective competitive alternatives are not available and a pipeline holds market power, then we may be required to show that our rates are reasonable.

Natural Gas Pipelines . Our interstate natural gas pipelines that provide services in interstate commerce are regulated by the FERC under the Natural Gas Act of 1938 (“NGA”). Under the NGA, the rates for service on these interstate facilities must be just and reasonable and not unduly discriminatory. We operate these interstate facilities pursuant to tariffs which set forth rates and terms and conditions of service. These tariffs must be filed with and approved by the FERC pursuant to its regulations and orders. Our tariff rates may be lowered on a prospective basis only by the FERC if it finds, on its own initiative or as a result of challenges to the rates by third parties, that they are unjust, unreasonable or otherwise unlawful. Unless the FERC grants specific authority to charge market-based rates, our rates are derived and charged based on a cost-of-service methodology.

The FERC’s authority over companies that provide natural gas pipeline transportation or storage services in interstate commerce also extends to: (i) the construction and operation of certain new facilities; (ii) the acquisition, extension, disposition or abandonment of such facilities; (iii) the maintenance of accounts and records; (iv) the initiation, extension and termination of regulated services; and (v) various other matters. The FERC’s rules require interstate pipelines and their affiliates to adhere to Standards of Conduct that, among other things, require that transportation and marketing employees function independently of each other. The Energy Policy Act of 2005 amended the NGA to add an anti-manipulation provision. Pursuant to that act, the FERC established rules prohibiting energy market manipulation. A violation of these rules may subject us to civil penalties, disgorgement of unjust profits, or appropriate non-monetary remedies imposed by the FERC. In addition, the Energy Policy Act of 2005 amended the NGA and the Natural Gas Policy Act of 1978 (“NGPA”) to increase civil and criminal penalties for any violation of the NGA, NGPA and any rules, regulations or orders of the FERC up to $1 million per day per violation.

In March 2009, High Island Offshore System, L.L.C. (“HIOS LLC,” which owns HIOS) filed with the FERC a general rate change application under Section 4 of the NGA proposing, among other things, an increase in HIOS’ firm and interruptible transportation rates. Pursuant to the FERC’s order issued in April 2009, the rates went into effect, subject to refund, in October 2009. In March 2009, HIOS LLC also filed a petition requesting the FERC to declare that all facilities at and upstream of the High Island Area (“HIA”) Block 264 platform perform a non-jurisdictional gathering service. In September 2009, the FERC issued an order generally approving the petition. Finally, in January 2010, as a result of a platform fire at HIA Block 264, HIOS LLC filed an application seeking approval to remove three compressor units on the platform and to reduce the certificated capacity of HIOS. In April 2011, the FERC approved a settlement agreement resolving all outstanding issues in these three FERC proceedings, other than one “reserved issue” related to the rate proceeding that remains pending as of this report. We are unable to predict the outcome of that reserved issue.

Offshore Pipelines . Our offshore natural gas gathering pipelines and crude oil pipeline systems are subject to federal regulation under the Outer Continental Shelf Lands Act (“OCSLA”), which requires that all pipelines operating on or across the outer continental shelf provide nondiscriminatory transportation service.

Intrastate Pipelines

Liquids Pipelines . Certain of our pipeline systems operate within a single state and provide intrastate pipeline transportation services. These pipeline systems are subject to various regulations and statutes mandated by state regulatory authorities. Although the applicable state statutes and regulations vary widely, they generally require that intrastate pipelines publish tariffs setting forth all rates, rules and regulations applying to intrastate service, and generally require that pipeline rates and practices be reasonable and nondiscriminatory. Shippers may challenge our intrastate tariff rates and practices on our pipelines. Our intrastate liquids pipelines are subject to regulation in many states, including Alabama, Colorado, Illinois, Kansas, Louisiana, Minnesota, Mississippi, New Mexico, Oklahoma and Texas.

As noted above, Mid-America is currently involved in a rate case before the Kansas Corporation Commission (Docket No. 12-MDAP-068-RTS), involving Mid-America’s intrastate rates for certain movements within the state of Kansas. We are unable to predict the outcome of that proceeding.

Table of Contents

Natural Gas Pipelines . Our intrastate natural gas pipelines are subject to regulation in many states, including Colorado, Louisiana, New Mexico, Texas and Wyoming. Certain of our intrastate natural gas pipelines are also subject to limited regulation by the FERC under the NGPA because they provide transportation and storage service pursuant to Section 311 of the NGPA and Part 284 of the FERC’s regulations. Under Section 311 of the NGPA, an intrastate pipeline may transport gas on behalf of an interstate pipeline company or any local distribution company served by an interstate pipeline without becoming subject to the FERC’s jurisdiction under the NGA. However, such a pipeline is required to provide these services on an open and nondiscriminatory basis, to post certain transactional information on its website, and to make certain rate and other filings and reports in compliance with the FERC’s regulations. The rates for Section 311 services may be established by the FERC or the respective state agency, but such rates may not exceed a fair and equitable rate. The Texas Railroad Commission has the authority to regulate the rates and terms of service for our intrastate transportation service in Texas.

Under the terms of an uncontested settlement approved by the FERC in December 2010 in the last Section 311 rate proceeding for Enterprise Texas Pipeline LLC, we are required to justify the applicable settlement rates or establish new rates for NGPA Section 311 service on or before March 31, 2015.

Under the terms of an uncontested settlement that was approved by the FERC in July 2010 in the last Section 311 rate proceedings for the Acadian Gas System and Cypress pipelines, the pipelines are required to justify the applicable settlement rates or establish new rates for NGPA Section 311 service on or before July 13, 2014.

In September 2011, Acadian Gas LLC (“Acadian Gas”) filed a petition in FERC Docket No. PR11-129-000, seeking approval for new rates for NGPA Section 311 service on its new Haynesville Extension pipeline. As part of the petition for rate approval, Acadian Gas also filed changes to the Statement of Operating Conditions to reflect the new service. One party protested the changes to the Statement of Operating Conditions, but not the proposed new rates. We are unable to predict the outcome of that proceeding.

Natural Gas Sales

We are engaged in natural gas marketing activities. The resale of natural gas in interstate commerce is subject to FERC jurisdiction. However, under current federal rules the price at which we sell natural gas is not regulated insofar as the interstate market is concerned and, for the most part, is not subject to state regulation. Our affiliates that engage in natural gas marketing may be considered marketing affiliates of certain of our interstate natural gas pipelines. The FERC’s rules require pipelines and their marketing affiliates who sell natural gas in interstate commerce subject to the FERC’s jurisdiction to adhere to standards of conduct that, among other things, require that their transportation and marketing employees function independently of each other. Pursuant to the Energy Policy Act of 2005, the FERC has also established rules prohibiting energy market manipulation. A violation of these rules by us or our employees or agents may subject us to civil penalties, suspension or loss of authorization to perform such sales, disgorgement of unjust profits or other appropriate non-monetary remedies imposed by the FERC. The Federal Trade Commission and the Commodity Futures Trading Commission also have issued rules and regulations prohibiting market manipulation.

The FERC is continually proposing and implementing new rules and regulations affecting segments of the natural gas industry. For example, the FERC has adopted market monitoring and annual reporting regulations which are applicable to many intrastate pipelines and other entities that are otherwise not subject to the FERC’s NGA jurisdiction. The FERC also has established rules requiring the annual reporting of gas sales information, in order to increase transparency in natural gas markets. We cannot predict the ultimate impact of these regulatory changes on our natural gas marketing activities; however, we believe that any new regulations will also be applied to other natural gas marketers with whom we compete.

Marine Operations

Maritime Law . The operation of tow boats, barges and marine equipment create maritime obligations involving property, personnel and cargo under General Maritime Law. These obligations can create risks which are varied and include, among other things, the risk of collision and allision, which may precipitate claims for personal injury, cargo, contract, pollution, third party claims and property damages to vessels and facilities. Routine towage

Table of Contents

operations can also create risk of personal injury under the Jones Act and General Maritime Law, cargo claims involving the quality of a product and delivery, terminal claims, contractual claims and regulatory issues.

Jones Act . We are subject to the Jones Act and other federal laws that restrict maritime transportation between points in the U.S. to vessels built and registered in the U.S. and owned and manned by U.S. citizens. We are responsible for monitoring the ownership of our common units and other partnership interests. If we do not comply with these restrictions, we would be prohibited from operating our vessels in U.S. coastwise trade, and under certain circumstances we would be deemed to have undertaken an unapproved foreign transfer, resulting in severe penalties, including permanent loss of U.S. coastwise trading rights for our vessels, fines or forfeiture of the vessels.

In addition, the USCG and American Bureau of Shipping (“ABS”) maintain the most stringent regime of vessel inspection in the world, which tends to result in higher regulatory compliance costs for U.S.-flag operators than for owners of vessels registered under foreign flags of convenience. The Jones Act and General Maritime Law also provide damage remedies for crew members injured in the service of the vessel arising from employer negligence or vessel unseaworthiness. In certain circumstances, a Jones Act seaman can have dual employers under the borrowed servant doctrine.

Merchant Marine Act of 1936 . The Merchant Marine Act of 1936 is a federal law that provides that, upon proclamation by the U.S. President of a national emergency or a threat to the national security, the U.S. Secretary of Transportation (the “Transportation Secretary”) may requisition or purchase any vessel or other watercraft owned by U.S. citizens (including us, provided that we are considered a U.S. citizen for this purpose). If one of our tow boats or barges were purchased or requisitioned by the U.S. government under this law, we would be entitled to be paid the fair market value of the vessel in the case of a purchase or, in the case of a requisition, the fair market value of charter hire. However, if one of our tow boats is requisitioned or purchased and its associated barge or barges are left idle, we would not be entitled to receive any compensation for the lost revenues resulting from the idled barges. We also would not be entitled to be compensated for any consequential damages we suffer as a result of the requisition or purchase of any of our tow boats or barges.

Environmental and Safety Matters

The following sections describe the general impact of environmental and safety matters on our business. Additional information regarding environmental and safety risks are described under Item 1A of this annual report.

Our operations are subject to various environmental and safety requirements and potential liabilities under extensive federal, state and local laws and regulations. These include, without limitation: the Comprehensive Environmental Response, Compensation, and Liability Act (“CERCLA”); the Resource Conservation and Recovery Act (“RCRA”); the Federal Clean Air Act (“CAA”); the Federal Water Pollution Control Act of 1972, renamed and amended as the Clean Water Act (“CWA”); the Oil Pollution Act of 1990 (“OPA”); the Federal Occupational Safety and Health Act, as amended (“OSHA”); the Emergency Planning and Community Right to Know Act; and comparable or analogous state and local laws and regulations. Such laws and regulations affect many aspects of our present and future operations, and generally require us to obtain and comply with a wide variety of environmental registrations, licenses, permits, inspections and other approvals, with respect to air emissions, water quality, wastewater discharges and solid and hazardous waste management. Failure to comply with these requirements may expose us to fines, penalties and/or interruptions in our operations that could have a material adverse effect on our financial position, results of operations and cash flows. If a leak, spill or release of hazardous substances occurs at any facilities that we own, operate or otherwise use, or where we send materials for treatment or disposal, we could be held liable for all resulting liabilities, including investigation, remedial and clean-up costs. Likewise, we could be required to remove or remediate previously disposed wastes or property contamination, including groundwater contamination. Any or all of this could have a material adverse effect on our financial position, results of operations and cash flows.

We believe our operations are in material compliance with applicable environmental and safety laws and regulations and that compliance with existing environmental and safety laws and regulations are not expected to have a material adverse effect on our financial position, results of operations and cash flows. Environmental and safety laws and regulations are subject to change. The trend in environmental regulation has been to place more restrictions and limitations on activities that may be perceived to affect the environment, and thus there can be no

Table of Contents

assurance as to the amount or timing of future expenditures for environmental regulation compliance or remediation, and actual future expenditures may be different from the amounts we currently anticipate. Revised or additional regulations that result in increased compliance costs or additional operating restrictions, particularly if those costs are not fully recoverable from our customers, could have a material adverse effect on our financial position, results of operations and cash flows.

On occasion, we are assessed monetary sanctions by governmental authorities related to administrative or judicial proceedings involving environmental matters. See Item 3 of this annual report for a discussion of such matters where the amount of monetary sanctions sought is in excess of $100,000.

Air Emissions

Our operations are associated with emissions of air pollution and are subject to the CAA and comparable state laws and regulations including state implementation plans. These laws and regulations regulate emissions of air pollutants from various industrial sources, including certain of our facilities, and also impose various monitoring and reporting requirements. Such laws and regulations may require that we obtain pre-approval for the construction or modification of certain projects or facilities expected to produce air emissions or result in the increase of existing air emissions, obtain and strictly comply with air permits containing various emissions and operational limitations, or utilize specific emission control technologies to limit emissions.

Our failure to comply with these requirements could subject us to monetary penalties, injunctions, conditions or restrictions on operations, and enforcement actions. We may be required to incur certain capital expenditures in the future for air pollution control equipment in connection with obtaining and maintaining operating permits and approvals for air emissions, as well as to comply with pending regulations (e.g., Oil and Gas New Source Performance Standards). We believe, however, that such requirements will not have a material adverse effect on our operations, and the requirements are not expected to be any more burdensome to us than any other similarly situated company.

Climate Change Regulations

In the 111th Congress, numerous legislative measures were introduced that would have imposed restrictions or costs on greenhouse gas emissions, including from the oil and gas industry. Conversely, the 112th Congress, which convened in January 2011, slowed the federal efforts to implement greenhouse gas regulations, which resulted in certain states and regional partnerships taking the initiative. While the state efforts seem less burdensome, any such legislation may have the potential to affect our business, customers or the energy sector generally.

On an international level, the U.S. has been involved in negotiations regarding greenhouse gas reductions under the United Nations Framework Convention on Climate Change (“UNFCCC”). Other nations have already agreed to regulate emissions of greenhouse gases, pursuant to the UNFCCC and a subsidiary agreement known as the “Kyoto Protocol,” an international treaty pursuant to which participating countries have agreed to reduce their emissions of greenhouse gases to below 1990 levels by 2012. The U.S. is a party to the UNFCCC but did not ratify the Kyoto Protocol. Such negotiations have not thus far resulted in substantive changes that would affect domestic industrial sources in the U.S. and it is uncertain whether an international agreement will be reached or what the terms of any such agreement would be.

Following the U.S. Supreme Court’s decision in Massachusetts, et al. v. EPA , 549 U.S. 497 (2007), finding that greenhouse gases fall within the CAA definition of “air pollutant,” the EPA determined that greenhouse gases

Table of Contents

from certain sources “endanger” public health or welfare. As a result, the EPA has taken the position that existing CAA provisions require an assessment of greenhouse gas emissions within the permitting process for certain large new or modified stationary sources under the EPA’s Prevention of Significant Deterioration (“PSD”) and Title V permit programs beginning in 2011. Facilities triggering permit requirements may be required to reduce greenhouse gas emissions consistent with “best available control technology” standards if deemed to be cost-effective. Such changes will also affect state air permitting programs in states that administer the CAA under a delegation of authority, including states in which we have operations. Additionally, in November 2010, the EPA finalized rules expanding its Mandatory Greenhouse Gas Reporting Rule, originally promulgated in October 2009, to be applicable to the oil and natural gas industry. The expansion requires annual, on-site monitoring and additional inventory and reporting of greenhouse gas emissions and affects many of our existing operations and must be considered for future operations. Although subject to legal challenge, the EPA rules promulgated thus far are currently final and effective, and will remain so unless the regulations are overturned by a court ruling, or Congress adopts legislation altering the EPA’s regulatory authority.

A number of states, individually or in regional cooperation, have also imposed restrictions on greenhouse gas emissions under various policies and approaches, including establishing a cap on emissions, requiring efficiency measures, or providing incentives for pollution reduction, use of renewable energy, or use of fuels with lower carbon content. These initiatives include the following:

Ten states in the Northeast and Mid-Atlantic region signed a compact and have implemented rules to limit carbon dioxide emissions from power plants under the Regional Greenhouse Gas Initiative (“RGGI”), which requires electric generating facilities to purchase emissions allowances corresponding to their respective emissions under a cap-and-trade system. RGGI started its second compliance period (from 2012-2014) under the cap-and-trade program and is currently conducting a state by state evaluation of the efficiency, impacts and economic feasibility of the program.

The California Air Resources Board (“CARB”) has issued a series of rules under that state’s Global Warming Solutions Act, including restrictions on greenhouse gas emissions from industrial sources and regulating the carbon content of fuels. In December 2010, the CARB approved a resolution to develop a multi-year, comprehensive program designed to reduce greenhouse gas emissions to be in place by January 2012. On October 20, 2011, the requirements of this program were finalized and registration for covered entities must be completed by January 31, 2012.

§	In November 2010, the New Mexico Environmental Improvement Board adopted new regulations pursuant to state law establishing a greenhouse gas cap-and-trade system to be implemented by the New Mexico Environment Department. However, the cap-and-trade program was repealed in February 2012.

There have also been several court cases implicating greenhouse gas emissions and climate change issues that could have established a regulatory precedent. First, in September 2009, the U.S. Court of Appeals for the Second Circuit issued its decision in Connecticut v. American Electric Power Co. , 582 F.3d 309 (2d Cir. Sept. 21, 2009). With this case, the Second Circuit held that certain state and private plaintiffs could sue energy companies on the asserted basis that greenhouse gas emissions created a “public nuisance.” However, in June 2011, the U.S. Supreme Court held that the CAA and EPA actions displace the right to seek abatement of emissions under federal common law but left open whether state law tort actions were pre-empted. Second, a three-judge panel of the U.S. Court of Appeals for the Fifth Circuit initially upheld claims in Comer v. Murphy Oil USA , 585 F.3d 855 (5th Cir. Oct. 16, 2009), by property owners who suffered casualty losses in Hurricane Katrina alleging that certain energy, fossil fuel and chemical industries emitted greenhouse gases that contributed to global warming and ultimately exacerbated property damage from the hurricane. The Fifth Circuit subsequently vacated the panel decision and, because of a procedural issue, was unable to review the merits of the claims. In May 2011, the case was refiled in the Southern District of Mississippi with a focus on state law causes of action. A similar case, Native Village of Kivalina v. ExxonMobil Corp. , 663 F. Supp. 2d 863 (N.D. Cal. Sept. 30, 2009), dismissed similar claims for lack of subject matter jurisdiction, and this decision was appealed to the U.S. Court of Appeals for the Ninth Circuit where oral argument was heard in November 2011. While these cases expose other significant emission sources of greenhouse gases to similar litigation risk, there seems to be limited support for this type of legal action.

These federal, regional and state measures generally apply to industrial sources, including facilities in the oil and gas sector, and could increase the operating and compliance costs of our pipelines, natural gas processing plants, fractionation plants and other facilities. These regulations could also adversely affect market demand or pricing for our products or products served by our midstream infrastructure, by affecting the price of, or reducing the demand for, fossil fuels or providing competitive advantages to competing fuels and energy sources. The potential increase in the costs of our operations could include costs to operate and maintain our facilities, install new emission controls on our facilities, acquire allowances to authorize our greenhouse gas emissions, pay any taxes related to our greenhouse gas emissions, or administer and manage a greenhouse gas emissions program. While we may be able to include some or all of such increased costs in the rates charged by our pipelines or other facilities, such recovery of costs is uncertain and may depend on events beyond our control, including the outcome of future rate proceedings before the FERC and the provisions of any final regulations. In addition, changes in regulatory policies that result in a reduction in the demand for hydrocarbon products that are deemed to contribute to greenhouse gases, or restrictions on their use, may reduce volumes available to us for processing, transportation, marketing and storage.

Physical Impacts of Climate Change

There is considerable debate over global warming and the environmental effects of greenhouse gas emissions and associated consequences affecting global climate, oceans and ecosystems. As a commercial enterprise, we are not in a position to validate or repudiate the existence of global warming or various aspects of the scientific debate. However, if global warming is occurring, it could have an impact on our operations. For example, our facilities that are located in low lying areas such as the coastal regions of Louisiana and Texas may be at increased risk due to flooding, rising sea levels, or disruption of operations from more frequent and severe weather events. Facilities in areas with limited water availability may be impacted if droughts become more frequent or severe. Changes in climate or weather may hinder exploration and production activities or increase the cost of production of oil and gas resources and consequently affect the volume of hydrocarbon products entering our system. Changes in climate or weather may also affect consumer demand for energy or alter the overall energy mix. However, we are not in a position to predict the precise effects of global warming. We are providing this disclosure based on publicly available information on the matter.

Water

The CWA and comparable state laws impose strict controls on the discharge of oil and its derivatives into regulated waters. The CWA provides penalties for any discharges of petroleum products in reportable quantities and imposes substantial potential liability for the costs of removing petroleum or other hazardous substances. State laws for the control of water pollution also provide varying civil and criminal penalties and liabilities in the case of a release of petroleum or its derivatives in navigable waters or into groundwater. Spill prevention control and countermeasure requirements of federal laws require appropriate containment berms and similar structures to help prevent a petroleum tank release from impacting regulated waters. The EPA has also adopted regulations that require us to have permits in order to discharge certain storm water run-off. Storm water discharge permits may also be required by certain states in which we operate and may impose certain monitoring and other requirements. The CWA further prohibit discharges of dredged and fill material in wetlands and other waters of the U.S. unless authorized by an appropriately issued permit. We believe that our costs of compliance with these CWA requirements will not have a material adverse effect on our financial position, results of operations and cash flows.

The primary federal law for oil spill liability is the OPA, which addresses three principal areas of oil pollution: prevention, containment and clean-up and liability. The OPA applies to vessels, offshore platforms and onshore facilities, including terminals, pipelines and transfer facilities. In order to handle, store or transport oil above certain thresholds, shore facilities are required to file oil spill response plans with the USCG, the DOT’s Office of Pipeline Safety (“OPS”) or the EPA, as appropriate. Numerous states have enacted laws similar to the OPA. Under the OPA and similar state laws, responsible parties for a regulated facility from which oil is discharged may be liable for removal costs and natural resource damages. Any unpermitted release of petroleum or other pollutants from our pipelines or facilities could result in fines or penalties as well as significant remedial obligations.

Contamination resulting from spills or releases of petroleum products is an inherent risk within the petroleum pipeline industry. To the extent that groundwater contamination requiring remediation exists along our pipeline systems or other facilities as a result of past operations, we believe any such contamination could be

Table of Contents

controlled or remedied without having a material adverse effect on our financial position, results of operations and cash flows, but such costs are site specific, and there is no assurance that the effect will not be material in the aggregate.

Solid Waste

In our normal operations, we generate hazardous and non-hazardous solid wastes that are subject to requirements of the federal RCRA and comparable state statutes, which impose detailed requirements for the handling, storage, treatment and disposal of hazardous and solid waste. We also utilize waste minimization and recycling processes to reduce the volumes of our waste.

Endangered Species

The federal Endangered Species Act, as amended, and comparable state laws, may restrict activities that affect endangered and threatened species or their habitats. Some of our current or future planned facilities may be located in areas that are designated as a habitat for endangered or threatened species, and if so may limit or impose increased costs on facility construction or operation. In addition, the designation of previously unidentified endangered or threatened species could cause us to incur additional costs or become subject to operating restrictions or bans in the affected areas.

Environmental Remediation

CERCLA, also known as “Superfund,” imposes liability, often without regard to fault or the legality of the original act, on certain classes of persons who contributed to the release of a “hazardous substance” into the environment. These persons include the owner or operator of a facility where a release occurred and companies that disposed or arranged for the disposal of the hazardous substances found at a facility. Under CERCLA, responsible parties may be subject to joint and several liability for the costs of cleaning up the hazardous substances that have been released into the environment, for damages to natural resources and for the costs of certain health studies. CERCLA and RCRA also authorize the EPA and, in some instances, third parties to take actions in response to threats to the public health or the environment and to seek to recover the costs they incur from the responsible classes of persons. It is not uncommon for neighboring landowners and other third parties to file claims for personal injury and property damage allegedly caused by hazardous substances or other pollutants released into the environment. In the course of our ordinary operations, our pipeline systems and other facilities generate wastes that may fall within CERCLA’s definition of a “hazardous substance” or be subject to CERCLA and RCRA remediation requirements. It is possible that we could incur liability for remediation or reimbursement of remediation costs under CERCLA or RCRA for remediation at sites we currently own or operate, whether as a result of our or our predecessors’ operations, at sites that we previously owned or operated, or at disposal facilities previously used by us, even if such disposal was legal at the time it was undertaken.

In the fourth quarter of 2011, certain of our subsidiaries were named by the EPA as potentially responsible parties in connection with the U.S. Oil Recovery Superfund Site located in Pasadena, Texas. We believe that the eventual resolution of these matters will result in penalties and other costs exceeding $0.1 million.

Pipeline Safety Matters

We are subject to regulation by the DOT under the Accountable Pipeline and Safety Partnership Act of 1996, sometimes referred to as the Hazardous Liquid Pipeline Safety Act (“HLPSA”), and comparable state statutes relating to the design, installation, testing, construction, operation, replacement and management of our pipeline facilities. The HLPSA covers petroleum and petroleum products and requires any entity that owns or operates pipeline facilities to (i) comply with such regulations, (ii) permit access to and copying of records, (iii) file certain reports and (iv) provide information as required by the Transportation Secretary. In addition, our natural gas pipeline assets are subject to the DOT’s OPS under the Natural Gas Pipeline Safety Act (“NGPSA”). We believe we are in material compliance with these DOT regulations.

We are also subject to the DOT regulation requiring qualification of pipeline personnel. The regulation requires pipeline operators to develop and maintain a written qualification program for individuals performing

Table of Contents

covered tasks on pipeline facilities. The intent of this regulation is to ensure a qualified work force and to reduce the probability and consequence of incidents caused by human error. The regulation establishes qualification requirements for individuals performing covered tasks. In addition, we are subject to the DOT regulation that requires pipeline operators to institute certain control room procedures. These procedures were implemented in October 2011 and we believe we are in material compliance with these DOT regulations.

In addition, we are subject to the DOT pipeline integrity management regulations in 49 CFR Parts 192 and 195, which specify how companies should assess, evaluate, validate and maintain the integrity of pipeline segments that, in the event of a release, could impact High Consequence Areas (“HCAs”). HCAs are defined to include populated areas, unusually sensitive environmental areas and commercially navigable waterways. The regulation requires the development and implementation of an integrity management program that utilizes internal pipeline inspection, pressure testing or other equally effective means to assess the integrity of HCA pipeline segments. The regulation also requires periodic review of HCA pipeline segments to ensure that adequate preventative and mitigative measures exist and that companies take prompt action to address integrity issues raised by the assessment and analysis. In June 2008, the DOT extended its pipeline safety regulations, including integrity management requirements, to certain rural onshore hazardous liquid gathering lines and certain rural onshore low-stress hazardous liquid pipelines within a one-half mile buffer zone around “unusually sensitive areas.” In May 2011, the DOT amended the pipeline safety regulations to apply the regulations to rural low-stress hazardous liquid pipelines that are not covered by the regulations in 49 CFR Part 195. Therefore, effective October 1, 2011, the pipeline safety regulations apply to all small-diameter (less than 8 5/8 inches) rural low-stress pipelines located within a one-half mile buffer zone of an unusually sensitive area and to all rural low-stress pipelines of any diameter located outside such one-half mile buffer zones. We have identified our HCA pipeline segments and developed an appropriate integrity management program.

The DOT also issued an Advance Notice of Proposed Rulemaking in October 2010 in which it is considering whether to remove or modify regulatory exemptions that currently exist in the pipeline safety regulations for the gathering of hazardous liquids by pipelines in rural areas. The comment period for this notice ended in February 2011; however, we cannot predict the ultimate impact of the proposed changes on our operations at this time.

In January 2012, President Obama signed the Pipeline Safety, Regulatory Certainty, and Job Creation Act of 2011 into law. This legislation provides stronger oversight of the nation’s pipelines, increases the penalties for violations of pipeline safety rules, and complements the DOT’s other initiatives. This legislation increases the maximum fine for the most serious pipeline safety violations involving deaths, injuries or major environmental harm from $1 million to $2 million. In addition, the legislation improves pipeline transportation and safety by: (i) improving pipeline damage prevention measures and cracking down on third party pipeline damage; (ii) allowing the Transportation Secretary to require automatic and remote-controlled shut-off valves on new pipelines; (iii) requiring the Transportation Secretary to evaluate the effectiveness of expanding pipeline integrity management and leak detection requirements; (iv) improving the way the DOT and pipeline operators provide information to the public and emergency responders; and (v) reforming the process by which pipeline operators notify federal, state and local officials of pipeline accidents.

Risk Management Plans

We are subject to the EPA’s Risk Management Plan regulations at certain facilities. These regulations are intended to work with the OSHA Process Safety Management (“PSM”) regulations (see “ — Other Safety Matters” below) to minimize the offsite consequences of catastrophic releases. The regulations require us to develop and implement a risk management program that includes a five-year accident history, an offsite consequence analysis process, a prevention program and an emergency response program. We believe we are operating in material compliance with our risk management program.

Other Safety Matters

Certain of our facilities are also subject to the requirements of the federal OSHA and comparable state statutes. We believe we are in material compliance with OSHA and state requirements, including general industry standards, record keeping requirements and monitoring of occupational exposures.

Table of Contents

Certain of our facilities are subject to OSHA PSM regulations, which are designed to prevent or minimize the consequences of catastrophic releases of toxic, reactive, flammable or explosive chemicals. These regulations apply to any process which involves a chemical at or above the specified thresholds or any process which involves certain flammable liquid or gas. We believe we are in material compliance with the OSHA PSM regulations.

The OSHA hazard communication standard, the community right-to-know regulations under Title III of the federal Superfund Amendment and Reauthorization Act and comparable state statutes require us to organize and disclose information about the hazardous materials used in our operations. Certain parts of this information must be reported to federal, state and local governmental authorities and local citizens upon request. These laws and provisions of CERCLA require reporting of spills and releases of hazardous chemicals in certain situations.

Employees

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. As of December 31, 2011, there were approximately 6,900 EPCO personnel who spend all or a portion of their time engaged in our business. Approximately 6,600 of these individuals devote substantially all of their time to our affairs. For additional information regarding the ASA, see “—EPCO Administrative Services Agreement” under Note 15 of the Notes to Consolidated Financial Statements included under Item 8 of this annual report.

Available Information

As a publicly traded partnership, we electronically file certain documents with the SEC. We file annual reports on Form 10-K; quarterly reports on Form 10-Q; and current reports on Form 8-K (as appropriate); along with any related amendments and supplements thereto. Occasionally, we may also file registration statements and related documents in connection with equity or debt offerings.

We do not intend to incorporate the information on our website into this annual report.

Item 1A. Risk Factors .

An investment in our common units or debt securities involves certain risks. If any of the following key risks were to occur, it could have a material adverse effect on our financial position, results of operations and cash flows, as well as our ability to maintain or increase distribution levels. In any such circumstance and others described below, the trading price of our securities could decline and you could lose part or all of your investment.

Risks Relating to Our Business

Our standalone operating cash flow is derived primarily from cash distributions we receive from EPO .

The quarterly cash distributions paid by Enterprise Products Partners L.P. are derived from the cash distributions it receives from EPO. The amount of cash EPO can distribute principally depends upon the cash flow generated from its operations, which will fluctuate from quarter-to-quarter based on, among other things, the: (i) volume of hydrocarbon products transported on its gathering and transmission pipelines; (ii) throughput volumes in its processing and treating operations; (iii) fees charged and the margins realized for its various storage, terminaling, processing and transportation services; (iv) price of natural gas, crude oil and NGLs; (v) relationships among natural gas, crude oil and NGL prices, including differentials between regional markets; (vi) fluctuations in its working

Table of Contents

capital needs; (vii) level of its operating costs; (viii) prevailing economic conditions; and (ix) level of competition encountered by its businesses. In addition, the actual amount of cash EPO will have available for distribution will depend on factors such as: (i) the level of sustaining capital expenditures incurred; (ii) its cash outlays for expansion (or growth) capital projects and acquisitions; and (iii) its debt service requirements and restrictive covenants. Because of these factors, we may not have sufficient available cash each quarter to continue paying distributions at our current levels.

Furthermore, the amount of cash we have available for distribution is not solely a function of profitability, which will be affected by non-cash items such as depreciation, amortization and provisions for asset impairments. Our cash flows are also impacted by borrowings under credit agreements and similar arrangements. As a result, we may be able to make cash distributions during periods when we record losses and may not be able to make cash distributions during periods when we record net income. An inability on our part to pay cash distributions to partners at our current levels or projected levels could have an adverse effect on our financial position, results of operations and cash flows.

Changes in demand for and production of hydrocarbon products could have a material adverse effect on our financial position, results of operations and cash flows.

We operate predominantly in the midstream energy industry, which includes gathering, transporting, processing, fractionating and storing natural gas, NGLs, crude oil 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. 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.

Historically, the price of natural gas has been extremely volatile, and we expect this volatility to continue. The New York Mercantile Exchange (“NYMEX”) daily settlement price for natural gas for the prompt month contract in 2010 ranged from a high of $6.01 per MMBtu to a low of $3.29 per MMBtu. In 2011, the same index ranged from a high of $4.85 per MMBtu to a low of $2.99 per MMBtu.

Generally, prices of hydrocarbon products are subject to fluctuations in response to changes in supply, demand, market uncertainty and a variety of other uncontrollable factors, such as: (i) the level of domestic production and consumer product demand; (ii) the availability of imported oil and natural gas and actions taken by foreign oil and natural gas producing nations; (iii) the availability of transportation systems with adequate capacity; (iv) the availability of competitive fuels; (v) fluctuating and seasonal demand for oil, natural gas, NGLs and other hydrocarbon products; (vi) the impact of conservation efforts; (vii) governmental regulation and taxation of production; and (viii) prevailing economic conditions.

We are exposed to natural gas and NGL commodity price risk under certain of our natural gas processing and gathering and NGL fractionation contracts that provide for our fees to be calculated based on a regional natural gas or NGL price index or to be paid in-kind by taking title to natural gas or NGLs. A decrease in natural gas and NGL prices can result in lower margins from these contracts, which could have a material adverse effect on our financial position, results of operations and cash flows. Volatility in commodity prices may also have an impact on many of our customers, which in turn could have a negative impact on their ability to fulfill their obligations to us.

The crude oil, natural gas and NGLs currently transported, gathered or processed at our facilities originate from existing domestic and international resource basins, which naturally deplete over time. To offset this natural decline, our facilities will need access to production from newly discovered properties. Many economic and business factors beyond our control can adversely affect the decision by producers to explore for and develop new reserves. These factors could include relatively low oil and natural gas prices, cost and availability of equipment and labor, regulatory changes, capital budget limitations, the lack of available capital or the probability of success in finding hydrocarbons. A decrease in exploration and development activities in the regions where our facilities and other energy logistic assets are located could result in a decrease in volumes to our natural gas processing plants, natural gas, crude oil and NGL pipelines, NGL fractionators and offshore platforms, which could have a material adverse effect on our financial position, results of operations and cash flows.

Table of Contents

A decrease in demand for NGL products by the petrochemical, refining or heating industries could have a material adverse effect on our financial position, results of operations and cash flows.

Decreases in demand may be caused by prevailing economic conditions, reduced demand by consumers for the end products made with NGL products, increased competition from petroleum-based products due to pricing differences, adverse weather conditions, government regulations affecting prices and production levels of natural gas, the content of motor gasoline, or other reasons. For example:

Ethane is primarily used in the petrochemical industry as feedstock in the production of ethylene, one of the basic building blocks for a wide range of plastics and other chemical products. If natural gas prices increase significantly in relation to NGL product prices or if the demand for ethylene falls (and, therefore, the demand for ethane decreases), it may be more profitable for natural gas producers to leave the ethane in a mixed natural gas stream to be burned as fuel than to extract it for sale as an ethylene feedstock.

§	The demand for propane as a heating fuel is significantly affected by weather conditions. Unusually warm winters could cause the demand for propane to decline significantly and could cause a significant decline in the volumes of propane that we transport.

§	A reduction in demand for motor gasoline additives may reduce demand for isobutane, which could adversely impact the price of isobutane and reduce our operating margin from selling isobutane.

Propylene is sold to petrochemical companies for a variety of uses, principally for the production of polypropylene. Propylene is subject to rapid and material price fluctuations. Any downturn in the domestic or international economy could cause reduced demand for, and an oversupply of propylene, which could cause a reduction in the volumes of propylene that we sell and transport.

We face competition from third parties in our midstream energy businesses .

Even if crude oil and natural gas reserves exist in the areas served by our assets, we may not be chosen by producers in these areas to gather, transport, process, fractionate, store or otherwise handle the hydrocarbons extracted. We compete with other companies, including producers of oil and natural gas, for any such production on the basis of many factors, including but not limited to geographic proximity to the production, costs of connection, available capacity, rates and access to markets.

Our refined products, NGL and marine transportation businesses may compete with other pipelines and marine transportation companies in the areas they serve. We also compete with railroads and third party trucking operations in certain of the areas we serve. Competitive pressures may adversely affect our tariff rates or volumes shipped. Also, substantial new construction of inland marine vessels could create an oversupply and intensify competition for our marine transportation business.

The crude oil gathering and marketing business can be characterized by thin operating margins and intense competition for supplies of crude oil at the wellhead. A decline in domestic crude oil production could intensify this competition among gatherers and marketers. Our crude oil transportation business competes with common carriers and proprietary pipelines owned and operated by major oil companies, large independent pipeline companies, financial institutions with trading platforms and other companies in the areas where such pipeline systems deliver crude oil.

In our natural gas gathering business, we encounter competition in obtaining contracts to gather natural gas supplies, particularly new supplies. Competition in natural gas gathering is based in large part on reputation, efficiency, system reliability, gathering system capacity and pricing arrangements. Our key competitors in the gas gathering segment include independent gas gatherers and major integrated energy companies. Alternate gathering facilities are available to producers we serve, and those producers may also elect to construct proprietary gas gathering systems.

A significant increase in competition in the midstream energy industry could have a material adverse effect on our financial position, results of operations and cash flows.

Table of Contents

Our debt level may limit our future financial and operating flexibility.

As of December 31, 2011, we had approximately $12.95 billion in principal amount of consolidated senior long-term debt outstanding and approximately $1.53 billion in principal amount of junior subordinated debt outstanding. The amount of our future debt could have significant effects on our operations, including, among other things:

§	a substantial portion of our cash flow could be dedicated to the payment of principal and interest on our future debt and may not be available for other purposes, including the payment of distributions on our common units and capital expenditures;

§	credit rating agencies may take a negative view of our consolidated debt level;

§	covenants contained in our existing and future credit and debt agreements will require us to continue to meet financial tests that may adversely affect our flexibility in planning for and reacting to changes in our business, including possible acquisition opportunities;

§	our ability to obtain additional financing, if necessary, for working capital, capital expenditures, acquisitions or other purposes may be impaired or such financing may not be available on favorable terms;

§	we may be at a competitive disadvantage relative to similar companies that have less debt; and

§	we may be more vulnerable to adverse economic and industry conditions as a result of our significant debt level.

Our public debt indentures currently do not limit the amount of future indebtedness that we can incur, assume or guarantee. Although our credit agreements restrict our ability to incur additional debt above certain levels, any debt we may incur in compliance with these restrictions may still be substantial. For information regarding our long-term debt, see Note 12 of the Notes to Consolidated Financial Statements included under Item 8 of this annual report.

Our credit agreements and each of the indentures related to our public debt instruments include traditional financial covenants and other restrictions. For example, we are prohibited from making distributions to our partners if such distributions would cause an event of default or otherwise violate a covenant under our credit agreements. A breach of any of these restrictions by us could permit our lenders or noteholders, as applicable, to declare all amounts outstanding under these debt agreements to be immediately due and payable and, in the case of our credit agreements, to terminate all commitments to extend further credit.

Our ability to access capital markets to raise capital on favorable terms could be affected by our debt level, when such debt matures, and by prevailing market conditions. Moreover, if the rating agencies were to downgrade our credit ratings, we could experience an increase in our borrowing costs, difficulty assessing capital markets and/or a reduction in the market price of our securities. Such a development could adversely affect our ability to obtain financing for working capital, capital expenditures or acquisitions, or to refinance existing indebtedness. If we are unable to access the capital markets on favorable terms in the future, we might be forced to seek extensions for some of our short-term debt obligations or to refinance some of our debt obligations through bank credit, as opposed to long-term public debt securities or equity securities. The price and terms upon which we might receive such extensions or additional bank credit, if at all, could be more onerous than those contained in existing debt agreements. Any such arrangements could, in turn, increase the risk that our leverage may adversely affect our future financial and operating flexibility and thereby impact our ability to pay cash distributions at expected levels.

We may not be able to fully execute our growth strategy if we encounter illiquid capital markets or increased competition for investment opportunities.

Our growth strategy contemplates the development and acquisition of a wide range of midstream and other energy infrastructure assets while maintaining a strong balance sheet. This strategy includes constructing and acquiring additional assets and businesses that enhance our ability to compete effectively and to diversify our asset

Table of Contents

portfolio, thereby providing us with more stable cash flows. We consider and pursue potential joint ventures, standalone projects and other transactions that we believe may present opportunities to expand our business, increase our market position and realize operational synergies.

We will require substantial new capital to finance the future development and acquisition of assets and businesses. For example, for the year ended December 31, 2011, we spent $3.55 billion on growth capital projects, of which approximately $867 million was for the Haynesville Extension and $1.59 billion for Eagle Ford Shale projects. Based on information currently available, we estimate our consolidated capital spending for 2012 will approximate $3.8 billion, which includes estimated expenditures of $3.5 billion for growth capital projects and $315 million for sustaining capital expenditures. Any limitations on our access to capital may impair our ability to execute this growth strategy. If our cost of debt or equity capital becomes too expensive, our ability to develop or acquire accretive assets will be limited. We also may not be able to raise the necessary funds on satisfactory terms, if at all.

Any future tightening of the credit markets may have a material adverse effect on us by, among other things, decreasing our ability to finance growth capital projects or business acquisitions on favorable terms and by the imposition of increasingly restrictive borrowing covenants. In addition, the distribution yields of any new equity we may issue may be higher than historical levels, making additional equity issuances more expensive.

We also may compete with third parties in the acquisition of energy infrastructure assets that complement our existing asset base. Increased competition for a limited pool of assets could result in our losing to other bidders more often than in the past or acquiring assets at less attractive prices. Either occurrence could limit our ability to fully execute our growth strategy. Our inability to execute our growth strategy may materially adversely affect our ability to maintain or pay higher cash distributions in the future.

Our variable-rate debt and future maturities of fixed-rate, long-term debt make us vulnerable to increases in interest rates, which could have a material adverse effect on our financial position, results of operation and cash flows.

As of December 31, 2011, we had $14.48 billion in principal amount of consolidated long-term debt outstanding, including current maturities thereof. Of this amount, approximately $1.1 billion, or 7.6%, was subject to variable interest rates, either as long-term variable-rate debt obligations or as long-term fixed-rate debt converted to variable rates through the use of interest rate swaps. As of the date of this report, we have $500.0 million, $1.2 billion, $1.15 billion, $650.0 million and $750.0 million of senior notes maturing in 2012, 2013, 2014, 2015 and 2016, respectively. In addition, our $3.5 billion variable-rate revolving credit facility matures in 2016.

Should interest rates increase significantly, the amount of cash required to service our debt (including any future refinancing of our fixed-rate debt instruments) would increase. Additionally, from time to time, we may enter into additional interest rate swap arrangements, which could increase our exposure to variable interest rates. As a result, significant increases in interest rates could have a material adverse effect on our financial position, results of operations and cash flows.

An increase in interest rates may also cause a corresponding decline in demand for equity securities in general, and in particular, for yield-based equity securities such as our common units. A reduction in demand for our common units may cause their trading price to decline.

Operating cash flows from our capital projects may not be immediate.

We have announced and are engaged in multiple significant construction projects involving existing and new assets for which we have expended or will expend significant capital. Once construction of an asset is completed, there may be a period of time before it is placed into commercial service and begins generating operating cash flow. For example, if we build a new pipeline or expand an existing facility, the design, construction, development and installation of the new asset may occur over an extended period of time, and we may not receive any material increase in operating cash flow from the project until a period of time after it is placed in-service. If we experience any unanticipated or extended delays in generating operating cash flow from these projects, we may be

Table of Contents

required to reduce or reprioritize our capital budget, sell non-core assets, access the capital markets or decrease or limit distributions to unitholders in order to meet our capital requirements.

Our growth strategy may adversely affect our results of operations if we do not successfully integrate and manage the businesses that we acquire or if we substantially increase our indebtedness and contingent liabilities to make acquisitions.

Our growth strategy includes making accretive acquisitions. As a result, from time to time, we will evaluate and acquire assets and businesses that we believe complement our existing operations. We may be unable to successfully integrate and manage the businesses we acquire in the future. We may incur substantial expenses or encounter delays or other problems in connection with our growth strategy that could have a material adverse effect on our financial position, results of operations and cash flows. Moreover, acquisitions and business expansions involve numerous risks, such as:

§	difficulties in the assimilation of the operations, technologies, services and products of the acquired assets or businesses;

§	establishing the internal controls and procedures we are required to maintain under the Sarbanes-Oxley Act of 2002;

§	managing relationships with new joint venture partners with whom we have not previously partnered;

§	experiencing unforeseen operational interruptions or the loss of key employees, customers or suppliers;

§	inefficiencies and complexities that can arise because of unfamiliarity with new assets and the businesses associated with them, including with their markets; and

§	diversion of the attention of management and other personnel from day-to-day business to the development or acquisition of new businesses and other business opportunities.

If consummated, any acquisition or investment would also likely result in the incurrence of indebtedness and contingent liabilities and an increase in interest expense and depreciation, amortization and accretion expenses. As a result, our capitalization and results of operations may change significantly following a material acquisition. A substantial increase in our indebtedness and contingent liabilities could have a material adverse effect on our financial position, results of operations and cash flows. In addition, any anticipated benefits of a material acquisition, such as expected cost savings or other synergies, may not be fully realized, if at all.

Acquisitions that appear to increase our operating cash flows may nevertheless reduce our operating cash flows on a per unit basis.

Even if we make acquisitions that we believe will increase our operating cash flows, these acquisitions may ultimately result in a reduction of operating cash flow on a per unit basis, such as if our assumptions regarding a newly acquired asset or business did not materialize or unforeseen risks occurred. As a result, an acquisition initially deemed accretive based on information available at the time could turn out not to be. Examples of risks that could cause an acquisition to ultimately not be accretive include our inability to achieve anticipated operating and financial projections or to integrate an acquired business successfully, the assumption of unknown liabilities for which we become liable, and the loss of key employees or key customers. If we consummate any future acquisitions, our capitalization and results of operations may change significantly, and our unitholders will not have the opportunity to evaluate the economic, financial and other relevant information that we will in making such decisions. As a result of the risks noted above, we may not realize the full benefits we expect from a material acquisition, which could have a material adverse effect on our financial position, results of operations and cash flows.

Our actual construction, development and acquisition costs could materially exceed forecasted amounts.

We have announced and are engaged in multiple significant construction projects involving existing and new assets for which we have expended or will expend significant capital. These projects entail significant logistical, technological and staffing challenges. We may not be able to complete our projects at the costs we estimated at the time of each project’s initiation or that we currently estimate. For example, material and labor costs associated with our past projects in the Rocky Mountains region increased over time due to factors such as higher transportation costs and the availability of construction personnel. Similarly, force majeure events such as hurricanes along the U.S. Gulf Coast may cause delays, shortages of skilled labor and additional expenses for these construction and development projects, such as were experienced with Hurricanes Gustav and Ike in 2008.

If capital expenditures materially exceed expected amounts, then our future cash flows could be reduced, which, in turn, could reduce the amount of cash we expect to have available for distribution. In addition, a material increase in project costs could result in decreased overall profitability of the newly constructed asset once it is placed into commercial service.

Our construction of new assets is subject to regulatory, environmental, political, legal and economic risks, which may result in delays, increased costs or decreased cash flows.

One of the ways we intend to grow our business is through the construction of new midstream energy infrastructure assets. The construction of new assets involves numerous operational, regulatory, environmental, political and legal risks beyond our control and may require the expenditure of significant amounts of capital. These potential risks include, among other things, the following:

§	we may be unable to complete construction projects on schedule or at the budgeted cost due to the unavailability of required construction personnel or materials, accidents, weather conditions or an inability to obtain necessary permits;

§	we will not receive any material increase in operating cash flows until the project is completed, even though we may have expended considerable funds during the construction phase, which may be prolonged;

§	we may construct facilities to capture anticipated future production growth in a region in which such growth does not materialize;

since we are not engaged in the exploration for and development of natural gas reserves, we may not have access to third party estimates of reserves in an area prior to our constructing facilities in the area. As a result, we may construct facilities in an area where the reserves are materially lower than we anticipate;

§	in those situations where we do rely on third party reserve estimates in making a decision to construct assets, these estimates may prove inaccurate;

§	the completion or success of our construction project may depend on the completion of a third party construction project (e.g., a downstream crude oil refinery expansion) that we do not control and that may be subject to numerous of its own potential risks, delays and complexities; and

§	we may be unable to obtain rights-of-way to construct additional pipelines or the cost to do so may be uneconomical.

A materialization of any of these risks could adversely affect our ability to achieve growth in the level of our cash flows or realize benefits from expansion opportunities or construction projects, which could impact the level of cash distributions we pay to partners.

An indirect subsidiary of EPCO has pledged 65,000,000 of our common units as security under the credit facility of another privately held affiliate of EPCO. Upon an event of default under this credit facility, a change in ownership of these units could ultimately result.

Duncan Family Interests, Inc. has pledged 65,000,000 of our common units that it owns as security under the credit facility of another privately held affiliate of EPCO. This credit facility contains customary and other events of default of the borrower and certain of its affiliates, including us. An event of default, followed by a foreclosure on the pledged collateral, could ultimately result in a change in ownership of these units. A development of this nature could affect the market price of our common units.

The credit and risk profile of owners of our general partner and their privately held affiliates could adversely affect our risk profile, which could increase our borrowing costs, hinder our ability to raise capital or impact future credit ratings.

The credit and business risk profiles of the owners of our general partner and their privately held affiliates may factor into the credit evaluations of our partnership. This is because the general partner can exercise significant influence over the business activities of our partnership, including its cash distribution policy, acquisition strategy and business risk profile. Another factor that may be considered is the financial condition of owners of our general partner and their privately held affiliates, including the degree of their financial leverage and their dependence on cash flow from our partnership to service their indebtedness.

Affiliates of the entities controlling the owner of our general partner have significant indebtedness outstanding and are dependent principally on the cash distributions from their limited partner equity interests in us to service such indebtedness. Any distributions by us to such entities will be made only after satisfying our then current obligations to creditors.

Although we have taken certain steps in our organizational structure, financial reporting and contractual relationships to reflect the separateness of us and our general partner from the entities that control our general partner, our credit ratings and business risk profile could be adversely affected if the ratings and risk profiles of EPCO or the entities that control our general partner were viewed as substantially lower or more risky than ours. A development of this nature could affect the market price of our common units.

The interruption of cash distributions to us from our subsidiaries and joint ventures may affect our ability to satisfy our obligations and to make cash distributions to our partners.

On a standalone basis, Enterprise Products Partners L.P. is a holding company with no business operations and conducts all of its business through its wholly owned subsidiary, EPO. As a result, we depend upon the earnings and cash flows of EPO and its subsidiaries and joint ventures, and the distribution of that cash to us in order to meet our obligations and to allow us to make cash distributions to our partners. The ability of EPO and its subsidiaries and joint ventures to make cash distributions to us may be restricted by, among other things, the provisions of existing and future indebtedness, applicable state partnership and limited liability company laws and other laws and regulations, including FERC policies. In addition, the charter documents governing EPO’s joint ventures typically allow their respective joint venture management committees sole discretion regarding the occurrence and amount of distributions. Two of the joint ventures in which EPO participates have separate credit agreements that contain various restrictive covenants. Among other things, those covenants may limit or restrict the joint venture's ability to make cash distributions to us under certain circumstances. Accordingly, EPO’s joint ventures may be unable to make cash distributions to us at current levels, if at all. A material reduction in the cash distributions we receive from EPO (including those of its joint ventures) would impair our ability to pay cash distributions to our partners.

We may be unable to cause our joint ventures to take or not to take certain actions unless some or all of our joint venture participants agree.

We participate in several joint ventures. Due to the nature of some of these arrangements, each participant in these joint ventures has made substantial investments in the joint venture and, accordingly, has required that the relevant charter documents contain certain features designed to provide each participant with the opportunity to

Table of Contents

participate in the management of the joint venture and to protect its investment, as well as any other assets which may be substantially dependent on or otherwise affected by the activities of the joint venture. These participatory and protective features customarily include a governance structure that requires at least a majority-in-interest vote to authorize many basic activities of the joint venture and requires a greater voting interest (sometimes up to 100%) to authorize more significant activities. Examples of these more significant activities are large expenditures or contractual commitments, the construction or acquisition of assets, borrowing money or otherwise raising capital, transactions with affiliates of a joint venture participant, litigation matters, and transactions not in the ordinary course of the joint venture’s business, among others. Thus, without the concurrence of joint venture participants with enough voting interests, we may be unable to cause any of our joint ventures to take or not to take certain actions, even though those actions may be in the best interest of us or the particular joint venture.

Moreover, any joint venture owner may sell, transfer or otherwise modify its ownership interest in a joint venture, whether in a transaction involving third parties or the other joint venture owners. Any such transaction could result in us being required to partner with different or additional parties with whom we have not had a previous relationship.

If we are unable to agree with our joint venture partners on a significant matter, it could result in a material adverse effect on that joint venture’s financial condition, results of operation or cash flows. If the matter was significant to us on a consolidated basis, it could result in a material adverse effect on our financial condition, results of operation or cash flows.

A natural disaster, catastrophe, terrorist attack or other event could result in severe personal injury, property damage and environmental damage, which could curtail our operations and have a material adverse effect on our financial position, results of operations and cash flows.

Some of our operations involve risks of personal injury, property damage and environmental damage, which could curtail our operations and otherwise materially adversely affect our cash flow. For example, natural gas facilities operate at high pressures, sometimes in excess of 1,100 pounds per square inch. We also operate crude oil and natural gas facilities located underwater in the Gulf of Mexico, which can involve complexities, such as extreme water pressure. In addition, our marine transportation business is subject to additional risks, including the possibility of marine accidents and spill events. From time to time, our octane enhancement facility may produce MTBE for export, which could expose us to additional risks from spill events. Virtually all of our operations are exposed to potential natural disasters, including hurricanes, tornadoes, storms, floods and/or earthquakes. The location of our assets and our customers’ assets in the U.S. Gulf Coast region makes them particularly vulnerable to hurricane or tropical storm risk. In addition, terrorists may target our physical facilities and hackers may attack our electronic systems.

If one or more facilities or electronic systems that we own or that deliver products to us or that supply our facilities are damaged by severe weather or any other disaster, accident, catastrophe, terrorist attack or event, our operations could be significantly interrupted. These interruptions could involve significant damage to people, property or the environment, and repairs could take from a week or less for a minor incident to six months or more for a major interruption. Additionally, some of the storage contracts that we are a party to obligate us to indemnify our customers for any damage or injury occurring during the period in which the customers’ product is in our possession. Any event that interrupts the revenues generated by our operations, or which causes us to make significant expenditures not covered by insurance, could reduce our cash available for paying distributions and, accordingly, adversely affect the market price of our securities.

We believe that EPCO maintains adequate insurance coverage on our behalf, although insurance will not cover many types of interruptions that might occur, will not cover amounts up to applicable deductibles and will not cover all risks associated with certain of our products. As a result of market conditions, premiums and deductibles for certain insurance policies can increase substantially, and in some instances, certain insurance may become unavailable or available only for reduced amounts of coverage. For example, following the hurricanes in 2005 and 2008, certain types of insurance coverage for our Gulf of Mexico assets have become more expensive. In the future, circumstances may arise whereby EPCO may not be able to renew existing insurance policies on our behalf or procure other desirable insurance on commercially reasonable terms, if at all. If we were to incur a significant liability for which we were not fully insured, it could have a material adverse effect on our financial position, results

Table of Contents

of operations and cash flows. In addition, the proceeds of any such insurance may not be paid in a timely manner and may be insufficient if such an event were to occur.

An impairment of goodwill and intangible assets could reduce our earnings.

At December 31, 2011, our consolidated balance sheet reflected $2.09 billion of goodwill and $1.66 billion of intangible assets. Goodwill represents the excess of the purchase price of an acquired business over the amounts assigned to assets acquired and liabilities assumed in the transaction. Generally accepted accounting principles (“GAAP”) in the U.S. require us to test goodwill for impairment on an annual basis or when events or circumstances occur indicating that goodwill might be impaired. Long-lived assets such as intangible assets with finite useful lives are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. If we determine that any of our goodwill or intangible assets were impaired, we would be required to take an immediate non-cash charge to earnings with a correlative effect on partners’ equity and balance sheet leverage as measured by debt to total capitalization. For information regarding our Critical Accounting Policies and Estimates, see Item 7 of this annual report.

The use of derivative financial instruments could result in material financial losses by us.

Historically, we have sought to limit a portion of the adverse effects resulting from changes in energy commodity prices and interest rates by using derivative instruments. Derivative instruments typically include futures, forward contracts, swaps, options and other instruments with similar characteristics. Substantially all of our derivatives are used for non-trading activities.

To the extent that we hedge our commodity price and interest rate exposures, we will forego the benefits we would otherwise experience if commodity prices or interest rates were to change in our favor. In addition, even though monitored by management, hedging activities can result in losses that might be material to our financial condition, results of operations and cash flows. Such losses could occur under various circumstances, including those situations where a counterparty does not perform its obligations under a hedge arrangement, the hedge is not effective in mitigating the underlying risk, or our risk management policies and procedures are not followed. Adverse economic conditions, such as the financial crisis that developed in the fourth quarter of 2008 and continued into 2009, increase the risk of nonpayment or performance by our hedging counterparties.

See Note 6 of the Notes to Consolidated Financial Statements included under Item 8 of this annual report for a discussion of our derivative instruments and related hedging activities.

Our business requires extensive credit risk management that may not be adequate to protect against customer nonpayment.

Risks of nonpayment and nonperformance by customers are a major consideration in our businesses, and our credit procedures and policies may not be adequate to sufficiently eliminate customer credit risk. Further, adverse economic conditions, such as the credit crisis that developed in the fourth quarter of 2008 and continued into 2009, increase the risk of nonpayment and nonperformance by customers, particularly customers that are smaller companies. We manage our exposure to credit risk through credit analysis, credit approvals, credit limits and monitoring procedures, and for certain transactions may utilize letters of credit, prepayments, net out agreements and guarantees. However, these procedures and policies do not fully eliminate customer credit risk.

Our primary market areas are located in the Gulf Coast, Southwest, Rocky Mountain, Northeast and Midwest regions of the U.S. We have a concentration of trade receivable balances due from major integrated oil companies, independent oil companies and other pipelines and wholesalers. These concentrations of market areas may affect our overall credit risk in that the customers may be similarly affected by changes in economic, regulatory or other factors.

Table of Contents

See Note 2 of the Notes to Consolidated Financial Statements included under Item 8 of this annual report for a discussion of our allowance for doubtful accounts.

Our risk management policies cannot eliminate all commodity price risks. In addition, any non-compliance with our risk management policies could result in significant financial losses.

When engaged in marketing activities, it is our policy to maintain physical commodity positions that are substantially balanced between purchases, on the one hand, and sales or future delivery obligations, on the other hand. Through these transactions, we seek to earn a margin for the commodity purchased by selling the same commodity for physical delivery to third party users, such as producers, wholesalers, independent refiners, marketing companies or major oil companies. These policies and practices cannot, however, eliminate all price risks. For example, any event that disrupts our anticipated physical supply could expose us to risk of loss resulting from price changes if we are required to obtain alternative supplies to cover these transactions. We are also exposed to basis risks when a commodity is purchased against one pricing index and sold against a different index. Moreover, we are exposed to some risks that are not hedged, including price risks on product inventory, such as pipeline linefill, which must be maintained in order to facilitate transportation of the commodity on our pipelines. In addition, our marketing operations involve the risk of non-compliance with our risk management policies. We cannot assure you that our processes and procedures will detect and prevent all violations of our risk management policies, particularly if deception or other intentional misconduct is involved. If we were to incur a material loss related to commodity price risks, including non-compliance with our risk management policies, it could have a material adverse effect on our financial position, results of operations and cash flows.

Our pipeline integrity program as well as compliance with proposed pipeline safety legislation and periodic tank maintenance requirements may impose significant costs and liabilities on us.

The DOT requires pipeline operators to develop integrity management programs to comprehensively evaluate their pipelines, and take measures to protect pipeline segments located in HCAs. The majority of the costs to comply with this integrity management rule are associated with pipeline integrity testing and any repairs found to be necessary as a result of such testing. Changes such as advances of in-line inspection tools, identification of additional threats to a pipeline’s integrity and changes to the amount of pipe determined to be located in HCAs can have a significant impact on the costs to perform integrity testing and repairs. We will continue our pipeline integrity testing programs to assess and maintain the integrity of our pipelines. The results of these tests could cause us to incur significant and unanticipated capital and operating expenditures for repairs or upgrades deemed necessary to ensure the continued safe and reliable operation of our pipelines.

The DOT has extended its pipeline safety regulations, including integrity management requirements, to certain rural onshore hazardous liquid gathering lines and certain rural onshore low-stress hazardous liquid pipelines within a buffer area around “unusually sensitive areas.” In May 2011, the DOT issued the second phase of the Final Rule applying pipeline safety regulations to all remaining rural low stress pipelines. The issuance of these gathering and low-stress pipeline safety regulations, including requirements for integrity management of those pipelines, is likely to increase the operating costs of our pipelines subject to such new requirements.

The American Petroleum Institute Standard 653 (“API 653”) is an industry standard for the inspection, repair, alteration and reconstruction of existing storage tanks. API 653 requires regularly scheduled inspection and

Table of Contents

repair of tanks remaining in service. Periodic tank maintenance requirements could cause us to incur significant and unanticipated capital and operating expenditures for repairs or upgrades deemed necessary to ensure the continued safe and reliable operation of our storage tanks.

If we were to incur material costs in connection with our pipeline integrity program or new pipeline safety legislation or periodic tank maintenance requirements, it could have a material adverse effect on our financial condition, results of operations and cash flows.

Additional regulations that cause delays or deter new offshore oil and gas drilling could have a material adverse effect on our financial position, results of operations and cash flows.

In April 2010, in an event unrelated to Enterprise’s operations, the Deepwater Horizon drilling rig caught fire and sank in the Gulf of Mexico, resulting in an oil spill. As a result, in May 2010, the U.S. Department of the Interior (“Interior Department”) issued a six-month moratorium that halted drilling of uncompleted and new oil and gas wells (in water deeper than 500 feet) in the Gulf of Mexico with certain limited exceptions and halted consideration of drilling permits for deepwater wells. In addition to the moratorium, the Interior Department also canceled or delayed offshore oil and gas lease sales off the Mid-Atlantic coast and in Alaska. The Secretary of the Interior (“Interior Secretary”) withdrew the moratorium and replaced it in July 2010 with a suspension of certain offshore drilling activities that was to be effective through October 2010.

The drilling suspension was finally lifted by the Interior Secretary on October 12, 2010. However, the timing and process for approving applications for new permits to drill and the cost associated with compliance with various new and enhanced safety and environmental requirements (as discussed below) imposed following the Deepwater Horizon incident remains uncertain. The Interior Department has indicated that it will not issue drilling permits until well operators demonstrate that safety and environmental protection requirements for offshore exploration and production can be met. In general, and as discussed in greater detail below, well operators have been required to show that containment resources are available promptly in the event of another blowout and to certify that they have complied with all applicable regulations, including new drilling safety rules. At the end of February 2011, the Bureau of Ocean Energy Management, Regulation and Enforcement (“BOEMRE”), an office of the Interior Department which is charged with oversight of the United States’ oil, natural gas and other mineral resources on the Outer Continental Shelf, approved the first drilling permit that would have been subject to the drilling suspension.

In 2010, the BOEMRE issued a series of rules that increased regulatory requirements for offshore oil and gas operations. In June 2010, the BOEMRE issued a notice to holders of offshore oil and gas leases requiring compliance certifications and third party verification of certain inspection and design matters. Subsequently, the BOEMRE issued a notice to lessees that called for enhanced information regarding planning scenarios relating to blowouts, discharges of pollutants and prevention of accidents. In August 2010, another notice to lessees revised the environmental review process for offshore oil and gas development. In October 2010, the BOEMRE published an emergency drilling safety rule that imposed additional requirements for well bore integrity and well control equipment and procedures, including provisions addressing blowout preventers and the use of drilling fluids. This interim final rule became effective immediately, but is subject to future changes that may be made by the regulatory agency in response to public comments. In October 2010, the BOEMRE also published a final rule requiring safety and environmental management systems for all oil and gas operations on the Outer Continental Shelf. In November 2010, the BOEMRE issued a notice to lessees requiring certifications and a demonstration that the well operator has access to and can deploy containment resources adequate to respond to a blowout or other loss of well control. Effective October 2011, the BOEMRE was reorganized and replaced by the Bureau of Ocean Energy Management (the “BOEM”) and the Bureau of Safety and Environment Enforcement.

In addition to federal regulatory activity, at least one state has ordered enhanced inspections of oil and gas rigs and required more stringent disaster preparedness plans, and it is possible that other state-level requirements will be imposed on offshore energy production activities.

The effect of new regulatory requirements on offshore energy development in the Gulf of Mexico following the Deepwater Horizon incident, including the prospects and timing of securing permits for offshore energy production activities, are evolving and uncertain. Such uncertainty may cause companies to curtail or delay

Table of Contents

oil and gas drilling activities, or to redirect resources to other areas such as West Africa, the Caribbean or South America, which may further delay the resumption of drilling activity in the Gulf of Mexico. It is uncertain at this time how and to what extent oil and natural gas supplies from the Gulf of Mexico and other offshore drilling areas will be affected.

In addition to federal regulatory actions, numerous legislative proposals were introduced in the 111th U.S. Congress in reaction to the Deepwater Horizon incident, some of which may be considered in the current legislative session. However, it is unclear and cannot be predicted whether and when Congress may pass legislation. Bills that have received attention include measures to: (i) modify or revoke liability limits and caps under the Oil Spill Liability Trust Fund, the OPA and certain other statutes; (ii) revise federal liability regimes to include health effects, personal injuries, and other tort claims; (iii) mandate more stringent safety measures and inspections under the OPA and OCSLA; (iv) expand environmental reviews and lengthen review timelines; (v) impose fees, increase taxes or remove tax exemptions; (vi) modify financial responsibility and insurance requirements for offshore energy activities; and (vii) require U.S. registration of oil rigs.

Given the scope and effect of the Deepwater Horizon incident to date, as well as statements made by the Interior Secretary, it is expected that additional regulatory compliance and agency review will be required prior to permitting new wells or continued drilling of existing wells, which may affect the cost and timing of oil and gas drilling in the Gulf of Mexico and other offshore areas. A decline in, or failure to achieve anticipated volumes of oil and natural gas supplies due to any of the foregoing factors could have a material adverse effect on our financial position, results of operations and cash flows through reduced gathering and transportation volumes, processing activities, or other midstream services.

Environmental costs and liabilities and changing environmental regulation, including climate change regulation, could have a material adverse effect on our financial position, results of operations and cash flows.

Our operations are subject to various environmental and safety requirements and potential liabilities under extensive federal, state and local laws and regulations. Further, we cannot ensure that existing environmental regulations will not be revised or that new regulations, such as regulations designed to reduce the emissions of greenhouse gases, will not be adopted or become applicable to us. Governmental authorities have the power to enforce compliance with applicable regulations and permits and to subject violators to civil and criminal penalties, including substantial fines, injunctions or both. Certain environmental laws, including CERCLA and analogous state laws and regulations, may impose strict, joint and several liability for costs required to clean-up and restore sites where hazardous substances or hydrocarbons have been disposed or otherwise released. Moreover, third parties, including neighboring landowners, may also have the right to pursue legal actions to enforce compliance or to recover for personal injury and property damage allegedly caused by the release of hazardous substances, hydrocarbons or other waste products into the environment. Future environmental law developments, such as stricter laws, regulations, permits or enforcement policies, could significantly increase some costs of our operations, including those incurred in connection with the handling, manufacture, use, emission or disposal of substances and wastes.

Climate Change Risks

Climate change regulation is one area of potential future environmental law development. Responding to scientific reports regarding threats posed by global warming, the U.S. Congress has considered legislation to reduce emissions of greenhouse gases. In addition, some states, including states in which our facilities or operations are located, have individually or in regional cooperation, imposed restrictions on greenhouse gas emissions under various policies and approaches, including establishing a cap on emissions, requiring efficiency measures, or providing incentives for pollution reduction, use of renewable energy sources, or use of replacement fuels with lower carbon content. Among these, ten states in the Northeast and Mid-Atlantic region signed a compact and have implemented rules to limit carbon dioxide emissions from power plants under the RGGI, which requires electric generation facilities to purchase emissions allowances corresponding to their respective emissions under a cap-and-trade system. The CARB has issued a series of rules under that state’s Global Warming Solutions Act, including restrictions on greenhouse gas emissions from industrial sources and regulating the carbon content of fuels. Beginning in January 2012, the CARB requires certain emission sources in California to acquire allowances for

Table of Contents

greenhouse gas emissions under its cap-and-trade system. In addition, in November 2010, the New Mexico Environmental Improvement Board adopted new regulations pursuant to state laws establishing a greenhouse gas cap-and-trade system to be implemented by the New Mexico Environment Department; however, this program was repealed in February 2012.

The EPA has also taken action under the CAA to regulate greenhouse gas emissions. In November 2010, the EPA finalized rules expanding its Mandatory Greenhouse Gas Reporting Rule, originally promulgated in October 2009, to be applicable to the oil and natural gas industry, which may affect certain of our existing or future operations and require us to inventory and report our emissions. In addition, the EPA has taken the position that existing CAA provisions require an assessment of greenhouse gas emissions within the permitting process for certain large new or modified stationary sources under the EPA’s PSD and Title V permit programs. Facilities triggering permit requirements may be required to reduce greenhouse gas emissions consistent with “best available control technology” standards if deemed to be cost-effective. Such changes will also affect state air permitting programs in states that administer the CAA under a delegation of authority, including states in which we have operations. The EPA has also announced its intention to promulgate additional regulations restricting greenhouse gas emissions, including rules applicable to the power generation sector and oil refining sector.

The adoption and implementation of any regulations imposing reporting obligations on, or limiting emissions of greenhouse gases from, our equipment and operations could require us to incur significant costs to reduce emissions of greenhouse gases associated with our operations or could adversely affect demand for the crude oil, natural gas or other hydrocarbon products that we transport, store or otherwise handle in connection with our midstream services. The potential increase in our operating costs could include costs to operate and maintain our facilities, install new emission controls on our facilities, acquire allowances to authorize our greenhouse gas emissions, pay any taxes related to our greenhouse gas emissions, and administer and manage a greenhouse gas emissions program. We may not be able to recover such increased costs through customer prices or rates. In addition, changes in regulatory policies that result in a reduction in the demand for hydrocarbon products that are deemed to contribute to greenhouse gases, or restrictions on their use, may reduce volumes available to us for processing, transportation, marketing and storage.

Moreover, there have been several court cases implicating greenhouse gas emissions and climate change issues that could establish precedent that may indirectly affect our business, customers or the energy sector in general. First, in September 2009, the U.S. Court of Appeals for the Second Circuit issued its decision in Connecticut v. American Electric Power Co. , 582 F.3d 309 (2d Cir. Sept. 21, 2009). With this case, the Second Circuit held that certain state and private plaintiffs could sue energy companies on the asserted basis that greenhouse gas emissions created a “public nuisance.” However, in June 2011, the U.S. Supreme Court held that the CAA and EPA actions displace the right to seek abatement of emissions under federal common law but left open whether state law tort actions were pre-empted. Second, a three-judge panel of the U.S. Court of Appeals for the Fifth Circuit initially upheld claims in Comer v. Murphy Oil USA , 585 F.3d 855 (5th Cir. Oct. 16, 2009), by property owners who suffered casualty losses in Hurricane Katrina alleging that certain energy, fossil fuel and chemical industries emitted greenhouse gases that contribute to global warming and ultimately exacerbated property damage from the hurricane. The Fifth Circuit subsequently vacated the panel decision, and because of a procedural issue, was unable to review the merits of the claims. In May 2011, the case was refiled in the Southern District of Mississippi with a focus on state law causes of action. A similar case, Native Village of Kivalina v. ExxonMobil Corp. , 663 F. Supp. 2d 863 (N.D. Cal. Sept. 30, 2009), dismissed similar claims for lack of subject matter jurisdiction, and this decision was appealed to U.S. Court of Appeals for the Ninth Circuit where oral argument was heard in November 2011. These cases could establish legal precedent that may expose other significant emission sources of greenhouse gases to similar litigation risk.

These developments, or any future actions, could have a material adverse effect on our financial position, results of operations and cash flows. While we may be able to include some or all of such increased costs in the rates charged by our pipelines or other facilities, such recovery of costs is uncertain and may depend on events beyond our control, including the outcome of future rate proceedings before the FERC and the provisions of any final legislation.

In addition, global warming could have an impact on our physical operations and energy markets. For example, our facilities that are located in low lying areas such as the coastal regions of Louisiana and Texas may be

Table of Contents

at increased risk due to flooding, rising sea levels, or disruption of operations from more frequent and severe weather events. Facilities in areas with limited water availability may be impacted if droughts become more frequent or severe. Changes in climate or weather may hinder exploration and production activities or increase or decrease the cost of production of oil and gas resources and consequently affect the volume of hydrocarbon products entering our system. Changes in climate or weather may also affect consumer demand for energy or alter the overall energy mix.

Hydraulic Fracturing Risks

Certain of our customers employ hydraulic fracturing techniques to stimulate natural gas production from unconventional geological formations (including shale formations), which entails the injection of pressurized fracturing fluids (consisting of water, sand and certain chemicals) into a well bore. The federal Energy Policy Act of 2005 amended the Underground Injection Control provisions of the federal Safe Drinking Water Act (“SDWA”) to exclude hydraulic fracturing from the definition of “underground injection” under certain circumstances. However, the repeal of this exclusion has been advocated by certain advocacy organizations and others in the public. Legislation to amend the SDWA to repeal this exemption and require federal permitting and regulatory control of hydraulic fracturing, as well as legislative proposals to require disclosure of the chemical components of the fluids used in the fracturing process, were proposed in recent sessions of Congress. Similar legislation could be introduced in the future.

The EPA has commenced a study of the potential environmental impact of hydraulic fracturing, the results of which are anticipated to be available in late 2012. A recent EPA report related to hydraulic fracturing in a production field in Wyoming suggested that there may be a connection between hydraulic fracturing and water quality at the site, although the data remains in dispute. In addition, in October 2011, the EPA announced its intention to propose regulations by 2014 under the CWA to regulate wastewater discharges from hydraulic fracturing and other natural gas production activities. Last year, a committee of the U.S. House of Representatives commenced investigations into hydraulic fracturing practices. The Interior Department has announced that it will consider regulations relating to the use of hydraulic fracturing techniques on public lands and disclosure of fracturing fluid components.

Some states and localities have adopted, and others are considering adopting, regulations or ordinances that could restrict hydraulic fracturing in certain circumstances, or that would impose higher taxes, fees or royalties on natural gas production. For example, New York has imposed a de facto moratorium on the issuance of permits for certain hydraulic fracturing practices until an environmental review and potential new regulations are finalized. Significant controversy has surrounded hydraulic fracturing operations in the Marcellus Shale in Pennsylvania. Wyoming has also adopted legislation requiring drilling operators conducting hydraulic fracturing activities in that state to publicly disclose the chemicals used in the fracturing process. Lastly, Colorado and Texas now require recordkeeping and disclosure of fracturing fluid components to state officials under certain circumstances.

Increased regulation and attention given to the hydraulic fracturing process could lead to greater opposition to oil and gas drilling activities using hydraulic fracturing techniques, including increased litigation. Additional legislation or regulation could also lead to operational delays and/or increased operating costs in the production of oil and natural gas (including natural gas produced from shale plays like the Eagle Ford Shale, Haynesville Shale, Barnett Shale and Marcellus and Utica Shales) incurred by our customers or could make it more difficult to perform hydraulic fracturing. If these legislative and regulatory initiatives cause a material decrease in the drilling of new wells and related servicing activities, it may affect the volume of hydrocarbon projects available to our midstream business and have a material adverse effect on our financial position, results of operations and cash flows.

Recently proposed rules regulating air emissions from oil and natural gas operations could cause us to incur increased capital expenditures and operating costs, which may be significant.

In July 2011, the EPA proposed rules that would establish new air emission controls for oil and natural gas production and natural gas processing operations. Specifically, the EPA’s proposed rule package includes New Source Performance Standards to address emissions of sulfur dioxide and volatile organic compounds (“VOCs”), and a separate set of emission standards to address hazardous air pollutants frequently associated with oil and natural gas production and processing activities. The EPA’s proposal would require the reduction of VOC emissions from

Table of Contents

oil and natural gas production facilities by mandating the use of “green completions” for hydraulic fracturing, which requires the operator to recover rather than vent the gas and NGLs that come to the surface during completion of the fracturing process. The proposed rules also would establish specific requirements regarding emissions from compressors, dehydrators, storage tanks and other production equipment. In addition, the rules would establish new leak detection requirements for natural gas processing plants. The EPA will receive public comment and hold hearings regarding the proposed rules and must take final action on them during the first quarter of 2012. If finalized, these rules could require a number of modifications to our operations including the installation of new leak detection and related equipment. Compliance with such rules could result in significant costs, including increased capital expenditures and operating costs, which may adversely impact our business.

Federal, state or local regulatory measures could have a material adverse effect on our financial position, results of operations and cash flows.

The FERC regulates our interstate natural gas pipelines and natural gas storage facilities under the NGA, and our interstate NGL and petrochemical pipelines under the ICA. The STB regulates our interstate propylene pipelines. State regulatory agencies regulate our intrastate natural gas and NGL pipelines, intrastate storage facilities and gathering lines.

Under the NGA, the FERC has authority to regulate natural gas companies that provide natural gas pipeline transportation services in interstate commerce. Its authority to regulate those services is comprehensive and includes the rates charged for such services, terms and conditions of service, and certification and construction of new natural gas facilities for transportation service in interstate commerce. The FERC requires that our services are provided on a nondiscriminatory basis so that all shippers have open access to our interstate pipelines. Pursuant to the FERC’s jurisdiction over interstate natural gas pipeline rates, existing pipeline rates may be challenged by customer complaint or by the FERC, and proposed rate increases may be challenged by protest.

We have ownership interests in natural gas and crude oil pipeline facilities located in the Gulf of Mexico offshore Texas and Louisiana. These facilities are subject to regulation by the FERC and other federal agencies, including the Interior Department, under the OCSLA, and by the DOT’s OPS under the NGPSA.

Our intrastate NGL and natural gas pipelines are subject to regulation in many states, including Colorado, Louisiana, New Mexico, Texas and Wyoming. To the extent our intrastate pipelines engage in interstate transportation, they are also subject to regulation by the FERC pursuant to Section 311 of the NGPA. We also have natural gas underground storage facilities in Louisiana and Texas. Although state regulation is typically less onerous than regulation by the FERC, our provision of services on a nondiscriminatory basis are also subject to challenge by protest and complaint, respectively.

Although our natural gas gathering systems are generally exempt from FERC regulation under the NGA, our natural gas gathering operations could be adversely affected should they become subject to federal regulation of rates and services, or, if the states in which we operate adopt policies imposing more onerous regulation on gas gathering operations. Additional rules and legislation pertaining to these matters are considered and adopted from time to time at both state and federal levels. We cannot predict what effect, if any, such regulatory changes and legislation might have on our operations, but we could be required to incur additional capital expenditures.

Increasingly stringent federal, state and local laws and regulations governing worker health and safety and the construction and operation of marine vessels may significantly affect our marine transportation operations. Many aspects of the marine transportation industry are subject to extensive governmental regulation by the USCG, the DOT, the Department of Homeland Security, the National Transportation Safety Board (“NTSB”) and the U.S. Customs and Border Protection, and to regulation by private industry organizations such as the ABS. The USCG and the NTSB set safety standards and are authorized to investigate vessel accidents and recommend improved safety standards. The USCG is authorized to inspect vessels at will.

For a general overview of federal, state and local regulation applicable to our assets, see “Regulation” included within Item 1 and 2 of this annual report. This regulatory oversight can affect certain aspects of our business and the market for our products and could materially adversely affect our cash flows.

Table of Contents

We are subject to strict regulations at many of our facilities regarding employee safety, and failure to comply with these regulations could adversely affect our ability to make distributions to unitholders.

The workplaces associated with our facilities are subject to the requirements of OSHA, and comparable state statutes that regulate the protection of the health and safety of workers. In addition, the OSHA hazard communication standard requires that we maintain information about hazardous materials used or produced in our operations and that we provide this information to employees, state and local governmental authorities and local residents. The failure to comply with OSHA requirements or general industry standards, keep adequate records or monitor occupational exposure to regulated substances could expose us to liability, enforcement, and fines and penalties, and could have a material adverse effect on our financial position, results of operations and cash flows.

The rates of our regulated assets are subject to review and possible adjustment by federal and state regulators, which could adversely affect our revenues.

The FERC, pursuant to the ICA (as amended), the Energy Policy Act and rules and orders promulgated thereunder, regulates the tariff rates for our interstate common carrier pipeline operations. To be lawful under the ICA, interstate tariff rates, terms and conditions of service must be just and reasonable and not unduly discriminatory, and must be on file with the FERC. In addition, pipelines may not confer any undue preference upon any shipper. Shippers may protest (and the FERC may investigate) the lawfulness of new or changed tariff rates. The FERC can suspend those tariff rates for up to seven months. It can also require refunds of amounts collected pursuant to rates that are ultimately found to be unlawful and prescribe new rates prospectively. The FERC and interested parties can also challenge tariff rates that have become final and effective. The FERC also can order new rates to take effect prospectively and order reparations for past rates that exceed the just and reasonable level up to two years prior to the date of a complaint. Due to the complexity of rate making, the lawfulness of any rate is never assured. A successful challenge of our rates could adversely affect our revenues.

The FERC uses prescribed rate methodologies for approving regulated tariff rates for interstate liquids pipelines. The FERC’s indexing methodology currently allows a pipeline to increase its rates by a percentage linked to the PPI. As an alternative to using the indexing methodology, interstate liquids pipelines may elect to support rate filings by using a cost-of-service methodology, market-based rates or agreements with all of the pipeline’s shippers that the rate is acceptable. These methodologies may limit our ability to set rates based on our actual costs or may delay the use of rates reflecting increased costs. Changes in the FERC’s approved methodology for approving rates, or challenges to our application of that methodology, could adversely affect us. Adverse decisions by the FERC in approving our regulated rates could adversely affect our cash flow.

The intrastate liquids pipeline transportation services we provide are subject to various state laws and regulations that apply to the rates we charge and the terms and conditions of the services we offer. Although state regulation typically is less onerous than FERC regulation, the rates we charge and the provision of our services may be subject to challenge.

Our partnership status may be a disadvantage to us in calculating our cost of service for rate-making purposes.

In May 2005, the FERC issued a policy statement permitting the inclusion of an income tax allowance in the cost of service-based rates of a pipeline organized as a tax pass through partnership entity to reflect actual or potential income tax liability on public utility income, if the pipeline proves that the ultimate owners of its partnership interests have an actual or potential income tax liability on such income. The policy statement also provides that whether a pipeline’s owners have such actual or potential income tax liability will be reviewed by the FERC on a case-by-case basis. In December 2005, the FERC issued its first significant case-specific review of the income tax allowance issue in another pipeline partnership’s rate case. The FERC reaffirmed its new income tax allowance policy and directed the subject pipeline to provide certain evidence necessary for the pipeline to determine its income tax allowance. The new tax allowance policy and the December 2005 order were appealed to the U.S. Court of Appeals for the District of Columbia Circuit (“D.C. Circuit”). The D.C. Circuit denied these appeals in May 2007 and fully upheld the FERC’s new tax allowance policy and the application of that policy in the December 2005 order.

Table of Contents

In December 2006, the FERC issued a new order addressing rates on another pipeline. In the new order, the FERC refined its income tax allowance policy, and notably raised a new issue regarding the implication of the policy statement for publicly traded partnerships. It noted that the tax deferral features of a publicly traded partnership may cause some investors to receive, for some indeterminate duration, cash distributions in excess of their taxable income, which the FERC characterized as a “tax savings.” The FERC stated that it is concerned that this created an opportunity for those investors to earn an additional return, funded by ratepayers. Responding to this concern, the FERC chose to adjust the pipeline’s equity rate of return downward based on the percentage by which the publicly traded partnership’s cash flow exceeded taxable income.

In April 2008, the FERC issued a policy statement in which it declared that it would permit master limited partnerships (“MLPs”), such as us, to be included in rate of return proxy groups for determining rates for services by natural gas and crude oil pipelines. It also addressed the application to limited partnership pipelines of the FERC’s discounted cash flow methodology for determining rates of return on equity. The FERC applied the new policy to several ongoing proceedings involving other pipelines. The FERC’s rate of return policy remains subject to change.

In February 2011 and December 2011, the FERC issued an order and rehearing order in a pipeline proceeding addressing issues related to the inclusion of an income tax allowance for partnerships, particularly MLPs.

In each order, the FERC, among other things, reaffirmed its tax allowance policy, MLP Policy Statement, and the findings of the D. C. Circuit’s May 2007 opinion regarding the income tax allowance and related issues, and rejected arguments that challenged its current income tax policy (i.e., certain parties claimed that granting an MLP an income tax allowance results in a double recovery of the partner’s income taxes and claimed that an MLP’s regulatory return should be adjusted to reflect the benefit of tax deferrals from owning a partnership interest).

However, the FERC’s current income tax allowance policy and related issues continue to be contested issues and the FERC’s policy remains subject to change. Future challenges to the FERC’s treatment of income tax allowances in cost of service, particularly with respect to pipelines organized as partnerships, could result in changes to the FERC’s current policy and could adversely affect our revenues for any of our rates that are calculated using cost of service rate methodologies.

The adoption and implementation of new statutory and regulatory requirements for derivative transactions could have an adverse impact on our ability to hedge risks associated with our business and increase the working capital requirements to conduct these activities.

The Dodd-Frank Wall Street Reform and Consumer Protection Act enacted in 2010 (the “Dodd-Frank Act”) provides for new statutory and regulatory requirements for swaps and other financial derivative transactions, including oil and gas hedging transactions. Under the Dodd-Frank Act, we will be required to transact “clearable” derivatives on a Designated Contract Market (“DCM”) or a Swap Execution Facility (“SEF”) such as a futures exchange or board of trade registered with the Commodity Futures Trading Commission (“CFTC”). All derivative transactions including those that are not clearable on such a platform and are therefore executed on an over-the-counter, bi-lateral basis may be subject to new requirements that involve recordkeeping and reporting requirements, position limits and additional cash collateral or margin requirements. The Dodd-Frank Act requires the CFTC, federal regulators of banks and other financial institutions, or the prudential regulators, and the SEC to promulgate rules implementing the new law.

On October 18, 2011, the CFTC issued its final position limits rules under the Dodd-Frank Act. The position limit rules enumerated certain energy futures contracts as referenced contracts including NYMEX Light Sweet Crude Oil, New York Harbor Gasoline Blendstock, New York Harbor Heating Oil and Henry Hub Natural Gas. Any referenced contract or associated contracts directly or indirectly linked to a referenced contract will be subject to the new position limits rules. These rules include spot month limits and non-spot month limits which can only be exceeded by positions that meet certain criteria to qualify as a Bona Fide Hedge. Invoking Bona Fide Hedges will require new reporting requirements including the reporting of anticipatory transactions, transactions relying on pass through hedge exemptions and reporting where certain visibility levels are met or exceeded. The position limit rules will go into effect 60 days after the term “swap” is defined by the CFTC. While there is still

Table of Contents

some uncertainty with respect to how the enumerated bona fide hedging qualifications will be interpreted, we anticipate that substantially all of our derivative transactions would qualify as Bona Fide Hedges.

On July 14, 2011, the CFTC granted temporary exemptive relief from certain provisions of the Commodity Exchange Act that otherwise would have taken effect on July 16, 2011, the general effective date of title VII of the Dodd-Frank Act. On October 25, 2011, the CFTC proposed to extend the exemptive relief beyond the December 31, 2011 expiration date. On December 19, 2011, the CFTC issued a Final Order regarding the effective date for swap regulation, which addressed the comments received on the October 25, 2011, Notice of Proposed Amendment, and extended the potential latest expiration date of the exemptive relief to July 16, 2012. The CFTC continues to make progress on its rulemaking efforts and has not yet indicated an earlier expiration date for the exemptive relief granted.

On December 20, 2011, the CFTC approved two final rules that addressed how swap data will be reported to regulators and separately to the public. One rule established recordkeeping requirements and a regulatory reporting regime for swap markets. The other rule established a reporting regime for the public dissemination of swap transaction data in real-time. Both rules affect swap dealers, major swap participants, swap counterparties that are neither swap dealers or major swap participants including end-users, swap data repositories, swap execution facilities, designated contract markets and derivatives clearing organizations. While we do not believe the internal costs of reporting will be material to us, we have not been able to assess the full impact of these rules on our counterparties and our marketing and hedging activities. Costs of compliance by our counterparties, particularly with the use of pass through hedge exemptions, will likely be passed on to customers such as ourselves, thus decreasing the benefits to us of hedging transactions and reducing our profitability. In addition, the new recordkeeping and reporting rules expose us to the risk of financial penalties or disqualifications of transactions as Bona Fide Hedges due to potential failures in compliance with the documentation requirements.

The CFTC has not yet released final rules on margin or collateral requirements; however, it is possible that any new rules will increase the amount of cash required to support exchange and over-the-counter derivative transactions. The majority of our financial derivative transactions used for hedging purposes are currently executed and cleared over exchanges that already require the posting of margins or letters of credit based on initial and variation margin requirements. Depending on the rules and definitions adopted by the CFTC, we might in the future be required to provide additional cash margin or new cash collateral for our commodities hedging transactions whether cleared over an exchange or over-the-counter. Furthermore, it is possible that letters of credit issued by banks on our behalf will no longer be considered an acceptable form of margin support which would increase overall cash margin requirements.

Posting of additional cash margin or collateral could affect our liquidity (defined as unrestricted cash on hand plus available credit under our revolving credit facility) and reduce our ability to use cash for capital expenditures or other partnership purposes. A requirement to post additional cash margin or collateral could therefore reduce our ability to execute hedges necessary to reduce commodity price exposures thus protecting cash flows. We are at risk for reduced liquidity unless and until the CFTC adopts rules and definitions that relieve companies such as ourselves from requirements to post additional cash margins or collateral for our exchange or over-the-counter derivative hedging activities. Even if we ourselves are not required to post additional cash margin or collateral for our derivative contracts, the banks and other derivatives dealers who are our contractual counterparties will be required to comply with other new requirements under the Dodd-Frank Act and related rules, and the costs of their compliance will likely be passed on to customers such as ourselves, thus decreasing the benefits to us of hedging transactions and reducing our profitability.

EPCO’s employees may be subjected to conflicts in managing our business and the allocation of their time and compensation costs between our business and the business of EPCO and its other affiliates.

We have no officers or employees and rely solely on officers of our general partner and employees of EPCO. Certain of our general partner’s officers are also officers of EPCO and other affiliates of EPCO. These relationships may create conflicts of interest regarding business opportunities and other matters, and the resolution of any such conflicts may not always be in our or our unitholders’ best interests. In addition, these overlapping officers and employees allocate their time among us, EPCO and other privately held affiliates of EPCO. These

Table of Contents

officers and employees face potential conflicts regarding the allocation of their time, which could have a material adverse effect on our financial position, results of operations and cash flows.

We do not have a separate compensation committee, and certain elements of the compensation of our executive officers and other key employees (other than our CEO), including base salary, are not reviewed or approved by our independent directors. The Audit Committee of our general partner approves grants of equity awards under EPCO’s long-term incentive plans, including those granted to our CEO. The determination of executive officer and key employee compensation could involve conflicts of interest resulting in economically unfavorable arrangements for us. For a discussion of our executive compensation policies and procedures, see Item 11 of this annual report.

Risks Relating to Our Partnership Structure

We may issue additional securities without the approval of our common unitholders.

At any time, we may issue an unlimited number of limited partner interests of any type (to parties other than our affiliates) without the approval of our unitholders. Our partnership agreement does not give our common unitholders the right to approve the issuance of equity securities, including equity securities ranking senior to our common units. The issuance of additional common units or other equity securities of equal or senior rank will have the following effects: (i) the ownership interest of a unitholder immediately prior to the issuance will decrease; (ii) the amount of cash available for distribution on each common unit may decrease; (iii) the ratio of taxable income to distributions may increase; (iv) the relative voting strength of each previously outstanding common unit may be diminished; and (v) the market price of our common units may decline.

We may not have sufficient operating cash flows to pay cash distributions at the current level following establishment of cash reserves and payments of fees and expenses.

Because cash distributions on our common units are dependent on the amount of cash we generate, distributions may fluctuate based on our performance and capital needs. We cannot guarantee that we will continue to pay distributions at the current level each quarter. The actual amount of cash that is available to be distributed each quarter will depend upon numerous factors, some of which are beyond our control and the control of our general partner. These factors include, but are not limited to: (i) the volume of the products that we handle and the prices we receive for our services; (ii) the level of our operating costs; (iii) the level of competition in our business; (iv) prevailing economic conditions, including the price of and demand for oil, natural gas and other products we transport, store and market; (v) the level of capital expenditures we make; (vi) the amount and cost of capital we can raise compared to the amount of our capital expenditures and debt service requirements; (vii) restrictions contained in our debt agreements; (viii) fluctuations in our working capital needs; (ix) weather volatility; (x) cash outlays for acquisitions, if any; and (xi) the amount, if any, of cash reserves required by our general partner in its sole discretion.

Furthermore, the amount of cash that we have available for distribution is not solely a function of profitability, which will be affected by non-cash items such as depreciation, amortization and provisions for asset impairments. Our cash flows are also impacted by borrowings under credit agreements and similar arrangements. As a result, we may be able to make cash distributions during periods when we record losses and may not be able to make cash distributions during periods when we record net income. An inability on our part to pay cash distributions to partners could have a material adverse effect on our financial position, results of operations and cash flows.

We do not have the same flexibility as other types of organizations to accumulate cash and equity to protect against illiquidity in the future.

Unlike a corporation, our partnership agreement requires us to make quarterly distributions to our unitholders of all available cash, after taking into account reserves for commitments and contingencies, including capital and operating costs and debt service requirements. The value of our common units and other limited partner interests may decrease in correlation with any reduction in our cash distributions per unit. Accordingly, if we experience a liquidity problem in the future, we may not be able to issue more equity to recapitalize.

Table of Contents

Cost reimbursements and fees payable to EPCO and its affiliates, including our general partner, may be substantial and will reduce cash available for distribution to our unitholders.

Prior to making any distribution on our common units, we will reimburse EPCO and its affiliates, including officers and directors of our general partner, for all expenses they incur on our behalf, including allocated overhead. These amounts include all costs incurred in managing and operating our business, including costs for providing administrative staff and other support services to us, and overhead allocated to us by EPCO. Payment of these amounts could adversely affect our ability to pay cash distributions to our unitholders. EPCO has sole discretion to determine the amount of these expenses. In addition, EPCO and its affiliates may provide other services to us for which we will be charged fees as determined by EPCO.

Our general partner and its affiliates have limited fiduciary responsibilities to, and conflicts of interest with respect to, our partnership, which may permit it to favor its own interests to your detriment.

The directors and officers of our general partner and its affiliates have duties to manage our general partner in a manner that is beneficial to its members. At the same time, our general partner has duties to manage our partnership in a manner that is beneficial to us. Therefore, our general partner’s duties to us may conflict with the duties of its officers and directors to its members. Such conflicts may include, among others, the following:

§	neither our partnership agreement nor any other agreement requires our general partner or EPCO to pursue a business strategy that favors us;

decisions of our general partner regarding the amount and timing of asset purchases and sales, cash expenditures, borrowings, issuances of additional units, and the establishment of additional reserves in any quarter may affect the level of cash available to pay quarterly distributions to our unitholders;

§	under our partnership agreement, our general partner determines which costs incurred by it and its affiliates are reimbursable by us;

our general partner is allowed to resolve any conflicts of interest involving us and our general partner and its affiliates, and may take into account the interests of parties other than us, such as EPCO, in resolving conflicts of interest, which has the effect of limiting its fiduciary duty to our unitholders;

§	any resolution of a conflict of interest by our general partner not made in bad faith and that is fair and reasonable to us is binding on the partners and is not a breach of our partnership agreement;

§	affiliates of our general partner may compete with us in certain circumstances;

our general partner has limited its liability and reduced its fiduciary duties and has also restricted the remedies available to our unitholders for actions that might, without the limitations, constitute breaches of fiduciary duty. As a result of purchasing our units, you are deemed to consent to some actions and conflicts of interest that might otherwise constitute a breach of fiduciary or other duties under applicable law;

§	we do not have any employees and we rely solely on employees of EPCO and its affiliates;

§	in some instances, our general partner may cause us to borrow funds in order to permit the payment of distributions;

§	our general partner may cause us to pay it or its affiliates for any services rendered to us or entering into additional contractual arrangements with any of these entities on our behalf;

§	our general partner intends to limit its liability regarding our contractual and other obligations and, in some circumstances, may be entitled to be indemnified by us;

§	our general partner controls the enforcement of obligations owed to us by our general partner and its affiliates; and

Table of Contents

§	our general partner decides whether to retain separate counsel, accountants or others to perform services for us.

We have significant business relationships with entities controlled by EPCO and Dan Duncan LLC. For information regarding these relationships and related party transactions with EPCO and its affiliates, see Note 15 of the Notes to Consolidated Financial Statements included under Item 8 of this annual report. Additional information regarding our relationship with EPCO and its affiliates can be found under Item 13 of this annual report.

Unitholders have limited voting rights and are not entitled to elect our general partner or its directors. In addition, even if unitholders are dissatisfied, they cannot easily remove our general partner.

Unlike the holders of common stock in a corporation, unitholders have only limited voting rights on matters affecting our business and, therefore, limited ability to influence management’s decisions regarding our business. Unitholders did not elect our general partner or its directors and will have no right to elect our general partner or its directors on an annual or other continuing basis. The owners of our general partner choose the directors of our general partner.

Furthermore, if unitholders are dissatisfied with the performance of our general partner, they currently have no practical ability to remove our general partner or its officers or directors. Our general partner may not be removed except upon the vote of the holders of at least 60% of our outstanding units voting together as a single class. Since affiliates of our general partner currently own approximately 37.9% of our outstanding common units and 100% of our Class B Units, the removal of Enterprise GP as our general partner is highly unlikely without the consent of both our general partner and its affiliates. As a result of this provision, the trading price of our common units may be lower than other forms of equity ownership because of the absence of a takeover premium in the trading price.

Our partnership agreement restricts the voting rights of unitholders owning 20% or more of our common units.

Unitholders’ voting rights are further restricted by a provision in our partnership agreement stating that any units held by a person that owns 20% or more of any class of our common units then outstanding, other than our general partner and its affiliates, cannot be voted on any matter. In addition, our partnership agreement contains provisions limiting the ability of unitholders to call meetings or to acquire information about our operations, as well as other provisions limiting our unitholders’ ability to influence our management. As a result of this provision, the trading price of our common units may be lower than other forms of equity ownership because of the absence of a takeover premium in the trading price.

Our general partner has a limited call right that may require common unitholders to sell their common units at an undesirable time or price.

If at any time our general partner and its affiliates own 85% or more of the common units then outstanding, our general partner will have the right, but not the obligation, which it may assign to any of its affiliates or to us, to acquire all, but not less than all, of the remaining common units held by unaffiliated persons at a price not less than the then current market price. As a result, common unitholders may be required to sell their common units at an undesirable time or price and may therefore not receive any return on their investment. They may also incur a tax liability upon the sale of their common units.

Our common unitholders may not have limited liability if a court finds that limited partner actions constitute control of our business.

Under Delaware law, common unitholders could be held liable for our obligations to the same extent as a general partner if a court determined that the right of limited partners to remove our general partner or to take other action under our partnership agreement constituted participation in the “control” of our business. Under Delaware law, our general partner generally has unlimited liability for our obligations, such as our debts and environmental liabilities, except for those of our contractual obligations that are expressly made without recourse to our general partner.

Table of Contents

The limitations on the liability of holders of limited partner interests for the obligations of a limited partnership have not been clearly established in some of the states in which we do business. You could have unlimited liability for our obligations if a court or government agency determined that (i) we were conducting business in a state, but had not complied with that particular state’s partnership statute; or (ii) your right to act with other unitholders to remove or replace our general partner, to approve some amendments to our partnership agreement or to take other actions under our partnership agreement constituted “control” of our business.

Unitholders may have liability to repay distributions.

Under certain circumstances, our unitholders may have to repay amounts wrongfully returned or distributed to them. Under Section 17-607 of the Delaware Revised Uniform Limited Partnership Act, we may not make a distribution to our unitholders if the distribution would cause our liabilities to exceed the fair value of our assets. Liabilities to partners on account of their partnership interests and liabilities that are non-recourse to the partnership are not counted for purposes of determining whether a distribution is permitted. Delaware law provides that for a period of three years from the date of an impermissible distribution, limited partners who received the distribution and who knew at the time of the distribution that it violated Delaware law will be liable to the limited partnership for the distribution amount. A purchaser of common units who becomes a limited partner is liable for the obligations of the transferring limited partner to make contributions to the partnership that are known to such purchaser of common units at the time it became a limited partner and for unknown obligations if the liabilities could be determined from our partnership agreement.

Our general partner’s interest in us and the control of our general partner may be transferred to a third party without unitholder consent.

Our general partner, in accordance with our partnership agreement, may transfer its general partner interest without the consent of unitholders. In addition, our general partner may transfer its general partner interest to a third party in a merger or consolidation or in a sale of all or substantially all of its assets without the consent of our unitholders. Furthermore, there is no restriction in our partnership agreement on the ability of the sole member of our general partner, currently Dan Duncan LLC, to transfer its equity interests in our general partner to a third party. The new equity owner of our general partner would then be in a position to replace the Board of Directors and officers of our general partner with their own choices and to influence the decisions taken by the Board of Directors and officers of our general partner.

Tax Risks to Common Unitholders

Our tax treatment depends on our status as a partnership for federal income tax purposes, as well as our not being subject to a material amount of entity-level taxation by individual states. If the Internal Revenue Service were to treat us as a corporation for federal income tax purposes or if we were to become subject to a material amount of entity-level taxation for state tax purposes, then cash available for distribution to our unitholders would be substantially reduced.

The anticipated after-tax economic benefit of an investment in our common units depends, to an extent, on our being treated as a partnership for federal income tax purposes. We have not requested, and do not plan to request, a ruling from the Internal Revenue Service (“IRS”) on this matter.

If we were treated as a corporation for federal income tax purposes, we would pay federal income tax on our taxable income at the corporate tax rate (which is currently at a maximum of 35%) and we would also likely pay additional state income taxes at varying rates. Distributions to our unitholders would generally be taxed again as corporate dividends, and no income, gains, losses, deductions or credits would flow through to our unitholders. Because a tax would be imposed upon us as a corporation, the cash available for distribution to our unitholders would be substantially reduced. Thus, treatment of us as a corporation would result in a material reduction in the after-tax return to our unitholders, likely causing a substantial reduction in the value of our common units.

Current law may change, causing us to be treated as a corporation for federal income tax purposes or otherwise subjecting us to a material amount of entity level taxation. In addition, because of widespread state

Table of Contents

budget deficits and other reasons, several states are evaluating ways to enhance state-tax collections. If any additional state were to impose an entity-level tax upon us or our operating subsidiaries, the cash available for distribution to our unitholders would be reduced.

The tax treatment of publicly traded partnerships or an investment in our common units could be subject to potential legislative, judicial or administrative changes and differing interpretations, possibly on a retroactive basis.

The present federal income tax treatment of publicly traded partnerships, including us, may be modified by administrative, legislative or judicial interpretation at any time. Any modification to federal income tax laws and interpretations thereof may or may not be applied retroactively and could make it more difficult or impossible to meet the qualifying income exception in order for us to be treated as a partnership for federal income tax purposes (i.e., not taxable as a corporation). In addition, such changes may affect or cause us to change our business activities, affect the tax considerations of an investment in us, change the character or treatment of portions of our income, or otherwise adversely affect an investment in our common units. The Obama Administration and certain members of Congress have recently considered substantive changes to existing federal income tax laws that would adversely affect the tax treatment of certain types of publicly traded partnerships. We are unable to predict whether any of these changes or any other proposals will ultimately be enacted. Any such changes could negatively impact the value of an investment in our common units and the amount of cash available for distribution to our unitholders.

We prorate our items of income, gain, loss and deduction between transferors and transferees of our common units each month based upon the ownership of our common units on the first day of each month, instead of on the basis of the date a particular common unit is transferred.

We prorate items of income, gain, loss and deduction between transferors and transferees of our common units each month based upon the ownership of the units on the first day of each month, instead of on the basis of the date a particular unit is transferred. The use of this proration method may not be permitted under existing Treasury Regulations, and, accordingly, our counsel is unable to opine as to the validity of this method. If the IRS were to challenge this method or new Treasury Regulations were issued, we may be required to change the allocation of items of income, gain, loss and deduction among our unitholders.

A successful IRS contest of the federal income tax positions we take may adversely impact the market for our common units and the cost of any IRS contest will reduce our cash available for distribution to unitholders.

The IRS may adopt positions that differ from the positions we take, even positions taken with advice of counsel. It may be necessary to resort to administrative or court proceedings to sustain some or all of the positions we take. A court may not agree with some or all of the positions we take. Any contest with the IRS may adversely impact the taxable income reported to our unitholders and the income taxes they are required to pay. As a result, any such contest with the IRS may materially and adversely impact the market for our common units and the price at which our common units trade. In addition, the costs of any contest with the IRS, principally legal, accounting and related fees, will result in a reduction in cash available for distribution to our unitholders.

Even if our common unitholders do not receive any cash distributions from us, they will be required to pay taxes on their share of our taxable income.

Because our unitholders will be treated as partners to whom we will allocate taxable income (which could be different in amount from the cash that we distribute), our unitholders will be required to pay federal income taxes and, in some cases, state and local income taxes on their share of our taxable income, whether or not they receive any cash distributions from us. Our common unitholders may not receive cash distributions from us equal to their share of our taxable income or even equal to the actual tax liability resulting from their share of our taxable income.

Tax gain or loss on the disposition of our common units could be different than expected .

If a common unitholder sells common units, the unitholder will recognize a gain or loss equal to the difference between the amount realized in the sale and the unitholder’s tax basis in those common units. Prior distributions to a unitholder in excess of the total net taxable income a unitholder is allocated for a common unit,

Table of Contents

which decreased the unitholder’s tax basis in that common unit, will, in effect, become taxable income to the unitholder if the common unit is sold at a price greater than the unitholder’s tax basis in that common unit, even if the price the unitholder receives is less than the unitholder’s original cost. A substantial portion of the amount realized, whether or not representing gain, may be ordinary income to a unitholder. In addition, because the amount realized may include a unitholder’s share of our nonrecourse liabilities, a unitholder that sells common units may incur a tax liability in excess of the amount of the cash received from the sale.

Tax-exempt entities and non-U.S. persons face unique tax issues from owning our common units that may result in adverse tax consequences to them.

Investments in our common units by tax-exempt entities, such as individual retirement accounts (“IRAs”), other retirement plans and non-U.S. persons, raise issues unique to them. For example, virtually all of our income allocated to unitholders who are organizations exempt from federal income tax, including IRAs and other retirement plans, will be unrelated business taxable income and will be taxable to them. Distributions to non-U.S. persons will be reduced by withholding taxes at the highest applicable effective tax rate, and non-U.S. persons will be required to file U.S. federal income tax returns and pay tax on their share of our taxable income.

We will treat each purchaser of our common units as having the same tax benefits without regard to the common units purchased. The IRS may challenge this treatment, which could adversely affect the value of our common units.

Because we cannot match transferors and transferees of common units, we adopt depreciation and amortization positions that may not conform to all aspects of existing Treasury Regulations. A successful IRS challenge to those positions could adversely affect the amount of tax benefits available to a common unitholder. It also could affect the timing of these tax benefits or the amount of gain from a sale of common units and could have a negative impact on the value of our common units or result in audit adjustments to the unitholder’s tax returns.

Our common unitholders will likely be subject to state and local taxes and return filing requirements in states where they do not live as a result of an investment in our common units.

In addition to federal income taxes, our common unitholders will likely be subject to other taxes, such as state and local income taxes, unincorporated business taxes and estate, inheritance or intangible taxes that are imposed by the various jurisdictions in which we do business or own property even if the unitholder does not live in any of those jurisdictions. Our common unitholders will likely be required to file state and local income tax returns and pay state and local income taxes in some or all of these various jurisdictions. Further, they may be subject to penalties for failure to comply with those requirements. We may own property or conduct business in other states or foreign countries in the future. It is the responsibility of each unitholder to file its own federal, state and local tax returns.

The sale or exchange of 50% or more of the total interests in our capital and profits within any twelve-month period will result in the termination of our partnership for federal income tax purposes.

We will be considered to have technically terminated our partnership for federal income tax purposes if there is a sale or exchange of 50% or more of the total interests in our capital and profits within a twelve-month period. Our technical termination would, among other things, result in the closing of our taxable year for all unitholders, which could result in us filing two tax returns (and our unitholders could receive two Schedule K-1s) for one fiscal year. A technical termination could also result in the deferral of depreciation deductions allowable in computing our taxable income.

The IRS has recently announced a relief procedure whereby if a publicly traded partnership that has technically terminated requests and the IRS grants special relief, among other things, the partnership will be required to provide only a single Schedule K-1 to unitholders for the tax year in which the technical termination occurs.

Table of Contents

A unitholder whose common units are loaned to a “short seller” to cover a short sale of common units may be considered as having disposed of those common units. If so, the unitholder would no longer be treated for tax purposes as a partner with respect to those common units during the period of the loan and may recognize gain or loss from the disposition.

Because a common unitholder whose common units are loaned to a “short seller” to cover a short sale of common units may be considered as having disposed of the loaned units, the unitholder may no longer be treated for tax purposes as a partner with respect to those common units during the period of the loan to the short seller and the unitholder may recognize gain or loss from such disposition. Moreover, during the period of the loan to the short seller, any of our income, gain, loss or deduction with respect to those common units may not be reportable by the unitholder and any cash distributions received by the unitholder as to those common units could be fully taxable as ordinary income. Our counsel has not rendered an opinion regarding the treatment of a unitholder whose common units are loaned to a short seller to cover a short sale of common units; therefore, unitholders desiring to assure their status as partners and avoid the risk of gain recognition from a loan to a short seller are urged to modify any applicable brokerage account agreements to prohibit their brokers from borrowing their common units.

Item 3. Legal Proceedings .

As part of our normal business activities, we may be named as defendants in litigation and legal proceedings, including those arising from regulatory and environmental matters. Although we are insured against various risks to the extent we believe it is prudent, there is no assurance that the nature and amount of such insurance will be adequate, in every case, to indemnify us against liabilities arising from future legal proceedings. Except as described below, as of February 29, 2012, we are not aware of any material pending legal proceedings, other than routine litigation incidental to our business, to which we are a party. For more information regarding our litigation matters, see “—Litigation Matters” under Note 18 of the Notes to Consolidated Financial Statements included under Item 8 of this annual report, which subsection is incorporated by reference into this Item 3.

On occasion, we are assessed monetary sanctions by governmental authorities related to administrative or judicial proceedings involving environmental matters. The following is a discussion of such matters where the amount of monetary sanctions sought is in excess of $100,000. We do not believe that any expenditures related to such matters will be material to our financial statements.

In March 2007, a segment of our Mid-America Pipeline System was struck by a third party in Nebraska causing a release of 1,725 barrels of natural gasoline. In April 2010, another segment of our Mid-America Pipeline System ruptured as a result of historical damage to the pipeline, which resulted in the release of 1,669 barrels of natural gasoline. Furthermore, in August 2011, flooding on the Missouri river caused the release of 818 barrels of natural gasoline from a segment of the Mid-America Pipeline System. We are in contact with various federal and state governmental authorities regarding these releases, including the U.S. Department of Justice and EPA. We believe that the eventual resolution of these matters will result in penalties and other costs exceeding $0.1 million.

After concluding an internal audit in 2011, we contacted the New Mexico Environment Department to self-disclose possible air emission and permit compliance violations at our facilities located in New Mexico. We believe that the eventual resolution of these matters will result in penalties and other costs exceeding $0.1 million.

In the third quarter of 2011, we received three compliance orders from the Colorado Department of Public Health and Environment in connection with alleged violations of air pollution regulations and related permit requirements in 2008, 2009 and 2010 at our facilities located in Colorado. We believe that the

eventual resolution of these Colorado matters will result in penalties and other costs approximating $1.1 million.

In the fourth quarter of 2011, certain of our subsidiaries were named by the EPA as a potentially responsible party in connection with the U.S. Oil Recovery Superfund Site located in Pasadena, Texas. We believe that the eventual resolution of these matters will result in penalties and other costs exceeding $0.1 million.

We expect to fund our quarterly cash distributions primarily with cash provided by operating activities. Although the payment of cash distributions is not guaranteed, we expect to continue to pay comparable cash distributions in the future as those presented in the preceding table.

As discussed under “Noncontrolling Interests” within Note 13 of the Notes to Consolidated Financial Statements included under Item 8 of this annual report, the cash distributions paid by Enterprise to its limited partners other than Holdings prior to the Holdings Merger in November 2010 are a component of noncontrolling interests. For additional information regarding our cash flows from operating activities, see “Liquidity and Capital Resources” included under Item 7 of this annual report.

Common Units Authorized for Issuance Under Equity Compensation Plan

See “Securities Authorized for Issuance Under Equity Compensation Plans” under Item 12 of this annual report, which is incorporated by reference into this Item 5.

Issuer Purchases of Equity Securities

In December 1998, we announced a common unit repurchase program whereby we, together with certain affiliates, intended to repurchase up to 2,000,000 of our common units for the purpose of granting options to management and key employees (amount adjusted for the 2-for-1 unit split in May 2002). We have not repurchased any of our common units under this program since 2002. As of February 1, 2012, we and our affiliates could repurchase up to 618,400 additional common units under this repurchase program.

During the year ended December 31, 2011, 936,608 restricted common unit and similar unit awards granted to employees of EPCO vested and were converted to common units. Of this amount, 255,276 were sold back to us by the employees to cover their related withholding tax requirements. The total cost of these treasury units was approximately $10.7 million. We cancelled such treasury units immediately upon acquisition. The following table summarizes our repurchase activity during 2011 in connection with these vesting transactions:

Significant Recent Developments

Development of Our ATEX Express Long-Haul Ethane Pipeline

In January 2012, we announced the receipt of sufficient transportation commitments to support development of our 1,230-mile Appalachia to Texas pipeline (the “ATEX Express”) that will transport growing ethane production from the Marcellus and Utica Shale producing areas of Pennsylvania, West Virginia and Ohio to the U.S. Gulf Coast. Demand for ethane feedstock over more expensive crude oil-based derivatives within the Gulf Coast petrochemical market has reached over 1 MMBPD and continues to increase given current pricing differentials. Several petrochemical companies have made announcements to modify, expand or build new facilities that would use ethane as a feedstock. As currently designed, the ATEX Express will have the capacity to transport up to 190 MBPD of ethane from the Appalachian production areas to our storage and distribution assets in southeast Texas.

The project would utilize a combination of new and existing infrastructure. The northern portion of the ATEX Express involves construction of a pipeline that would originate in Pennsylvania and extend west, then southwest, to Indiana following existing pipeline corridors in order to minimize the footprint of the project. The southern portion of ATEX Express would utilize a significant portion of our existing Products Pipeline System, which would be reversed to accommodate southbound delivery of ethane to the U.S. Gulf Coast. At the southern terminus of the ATEX Express in Beaumont, we plan to construct a 55-mile pipeline to provide shippers with access to our NGL storage complex at Mont Belvieu, which would provide them with direct and indirect access to every ethylene plant in the U.S. We expect that the ATEX Express will begin commercial operations in the first quarter of 2014.

Plans to Construct a Crude Oil Pipeline in the Gulf of Mexico with Genesis

In January 2012, we announced the execution of crude oil transportation agreements with a consortium of six Gulf of Mexico producers that will provide the necessary support for construction of a crude oil gathering pipeline serving the Lucius oil and gas field located in the southern Keathley Canyon area of the deepwater central Gulf of Mexico. The pipeline will be constructed and owned by Southeast Keathley Canyon Pipeline Company, L.L.C. (“SEKCO”), which is a 50/50 joint venture owned by us and Genesis Energy, L.P. (“Genesis”). We will serve as construction manager and operator of the new deepwater pipeline (the “SEKCO Oil Pipeline”).

The 149-mile, 18-inch diameter SEKCO Oil Pipeline is being designed with a crude oil transportation capacity of 115 MBPD and would connect the third party owned Lucius-truss spar floating production platform to an existing junction platform at South Marsh Island 205 that is part of our Poseidon Oil Pipeline System. The Lucius production area is estimated to have more than 300 MMBbls of oil equivalent, with relatively shallow and highly productive reservoirs, primarily comprised of crude oil. The SEKCO Oil Pipeline is expected to begin service by mid-2014.

Sale of 22.8 Million Common Units of Energy Transfer Equity

In January 2012, we sold 22,762,636 common units of Energy Transfer Equity, L.P. (“Energy Transfer Equity”) in a private transaction, which generated cash proceeds of approximately $825.1 million. Proceeds from this sale were used for general company purposes, including funding capital expenditures. Our Other Investments business segment consists of our investment in the common units of Energy Transfer Equity. As of the date of this report, we own approximately 6 million common units of Energy Transfer Equity, which represent less than 3% of its common units outstanding at February 15, 2012.

Plans with Enbridge to Reverse the Seaway Pipeline

In November 2011, ConocoPhillips agreed to sell its 50% partnership interest in Seaway Crude Pipeline Company (“Seaway”) to Enbridge Inc. (“Enbridge”). This transaction closed in December 2011. We own the remaining 50% partnership interest in Seaway, which owns the Seaway crude oil pipeline system (the “Seaway pipeline”), and operate the Seaway pipeline. Historically, the 546-mile Seaway pipeline transported imported crude oil from Freeport, Texas to the Cushing, Oklahoma hub. The increase in crude oil production from Canada’s tar

Table of Contents

sands and U.S. fields like the Bakken in North Dakota and Niobrara in Kansas, Wyoming and Colorado, has led to an oversupply of oil at the Cushing hub. This oversupply at Cushing led to depressed prices for domestic crude oil production versus international and U.S. Gulf Coast benchmarks, which, in turn, created feedstock cost disadvantages for domestic refiners that rely primarily on imported crude oil. As a result of the change in ownership in Seaway, we and Enbridge Inc. agreed to reverse the direction of crude oil flows on the Seaway pipeline to enable it to transport oil from the oversupplied Cushing hub to U.S. Gulf Coast refiners.

Pending regulatory approval, the Seaway pipeline could operate in reversed service with an initial capacity of 150 MBPD during the second quarter of 2012. Following pump station additions and other modifications, which are anticipated to be completed in the first quarter of 2013, we anticipate the capacity of the reversed Seaway pipeline will be up to 400 MBPD (assuming a mix of light and heavy grades of crude oil). We expect that this capacity will be fully contracted by shippers. In anticipation of additional shipper demand, we launched an open season in January 2012 to support a further expansion of the Seaway pipeline’s transportation capacity.

The reversed Seaway pipeline will deliver crude oil from Cushing into the Houston, Texas market by utilizing affiliate and third party pipelines. Seaway plans to build a 45-mile pipeline that will link its pipeline to our Enterprise Crude Houston (“ECHO”) crude oil storage terminal, which is being constructed southeast of Houston. Completion of this pipeline segment is expected in the first quarter of 2013. In addition, Seaway plans to build an 85-mile pipeline from our ECHO facility to the Port Arthur/Beaumont, Texas refining center that would provide shippers access to the region’s heavy oil refining capabilities. Completion of this pipeline segment is expected in early 2014.

Expansion of Our Natural Gas Pipeline and Processing Infrastructure in the Eagle Ford Shale

In November 2011, we announced several new construction projects that would extend and expand our natural gas and NGL infrastructure in South Texas to accommodate expected production growth from the Eagle Ford Shale. As a result of additional demand from our Eagle Ford Shale producing customers, along with the execution of new gathering and processing agreements, we plan to expand natural gas processing capacity at our Yoakum facility (which is currently under construction) by an additional 300 MMcf/d. Once the expansion is completed, we expect our Yoakum facility will have total gas processing capacity of 900 MMcf/d. We also plan to increase the size of the NGL takeaway pipelines originating at the Yoakum plant to handle the expected increase in NGL production. We expect the Yoakum facility to commence operations in phases with the first 300 MMcf/d to be available by May 2012, the second 300 MMcf/d coming online in July 2012, and the third 300 MMcf/d to be available by February 2013. The new Yoakum plant will complement our seven existing natural gas processing plants in South Texas, which currently have the capacity to process approximately 1.5 Bcf/d.

In addition to the Yoakum expansion, we are constructing 62 miles of natural gas pipeline loops and increasing compression to gather and transport an additional 300 MMcf/d of liquids-rich Eagle Ford Shale natural gas. These pipeline expansion projects are also expected to begin service in the first quarter of 2013.

Sale of Our Mississippi Natural Gas Storage Facilities

In October 2011, we announced the execution of definitive agreements to sell our ownership interests in Crystal Holding L.L.C. (“Crystal”) to Boardwalk HP Storage Company, LLC for $550 million in cash, before

Table of Contents

working capital adjustments of $2.2 million. The transaction closed in December 2011 and we recorded a gain of $129.1 million on the sale. Crystal owns two underground salt dome natural gas storage facilities located near Petal and Hattiesburg, Mississippi having approximately 29 Bcf of total storage capacity and related pipelines. Proceeds from this sale were used for general company purposes, including the funding of capital expenditures.

Crystal’s operations were a component of our Onshore Natural Gas Pipelines & Services business segment. We have determined that Crystal’s operations do not meet the criteria to be classified as discontinued operations. Following the sale, we continue to have significant commercial contracts and operational arrangements at the Petal and Hattiesburg facilities, which are adjacent to and currently share operating assets with our retained Petal, Mississippi NGL storage facility.

Completion of the Duncan Merger

Development of the Texas Express Pipeline with Enbridge and Anadarko

In September 2011, we, along with Enbridge Energy Partners, L.P. (“Enbridge”) and Anadarko Petroleum Corporation (“Anadarko”), announced an agreement to design and construct a new NGL pipeline (the “Texas Express Pipeline”) that would originate in Skellytown, Texas and extend approximately 580 miles to NGL fractionation and storage facilities in Mont Belvieu, Texas. NGL volumes from the Rocky Mountains, Permian Basin and Mid-continent regions will be delivered to the Texas Express Pipeline through an interconnect with the Conway South segment of our Mid-America Pipeline System. The Texas Express Pipeline will help producers in West and Central Texas, the Rocky Mountains, Southern Oklahoma and the Mid-continent to maximize the value of their NGL production by providing additional takeaway capacity and enhanced access to the U.S. Gulf Coast NGL market. Initial transportation capacity on the Texas Express Pipeline is expected to be approximately 250 MBPD, which could be expanded to approximately 400 MBPD. The new pipeline will be constructed and owned by Texas Express Pipeline LLC, the membership interests of which are held by us (45% share), Enbridge (35% share) and Anadarko (20% share). We will serve as construction manager and operator of the Texas Express Pipeline.

In addition, the joint venture plans to construct and own two new NGL gathering systems. The first NGL gathering system will connect the Texas Express Pipeline to natural gas processing plants in the Anadarko/Granite Wash production area located in the Texas Panhandle and Western Oklahoma. The second NGL gathering system will connect the new pipeline to Barnett Shale gas processing plants located in Central Texas. Enbridge will serve as construction manager and operator of these NGL gathering systems. Subject to regulatory approvals, the Texas Express Pipeline and related NGL gathering systems are expected to begin service in the second quarter of 2013.

Plans to Build a Sixth NGL Fractionator at Our Mont Belvieu Complex

In October 2011, commercial operations at our fifth NGL fractionator at Mont Belvieu commenced. This new fractionator increases the total nameplate NGL fractionation capacity at our Mont Belvieu facility to 380 MBPD. When our sixth Mont Belvieu NGL fractionator is completed, we will have the capability to fractionate

Table of Contents

more than 450 MBPD of NGLs at our Mont Belvieu complex and our system-wide net fractionation capacity will increase to approximately 770 MBPD.

Expansion of Our South Texas Crude Oil Pipeline System

In May 2011, we announced plans to build an 80-mile extension of our South Texas Crude Oil Pipeline System (the “Phase II project”), which would allow us to serve growing production areas in the southwestern portion of the Eagle Ford Shale supply basin. The Phase II project, which is being designed with a crude oil transportation capacity of 200 MBPD, will originate at Lyssy, Texas (at the terminus of our previously announced 140-mile Phase I segment) and extend to Gardendale, Texas, where a new central delivery point is planned for construction that will feature 0.5 MMBbls of crude oil storage. The system’s Phase I pipeline expansion project, which is expected to have a crude oil transportation capacity of 350 MBPD, originates at Sealy, Texas and extends to Lyssy, Texas. Phase I of the expansion project includes construction of 2.4 MMBbls of crude oil storage along the new pipeline, including 0.6 MMBbls at Lyssy, Texas, 0.2 MMBbls at Milton, Texas, 0.4 MMBbls at Marshall, Texas, and 1.2 MMBbls at Sealy, Texas.

Phase I of the project is forecast to begin service by the second quarter of 2012, with Phase II set to commence operations in the first quarter of 2013. When completed, the approximately 220-miles of additional crude oil pipelines are expected to provide Eagle Ford Shale producers with access to the Texas Gulf Coast refining complex through our integrated midstream asset network, including our ECHO crude oil terminal which is under construction. The ECHO terminal will provide shippers with access to major refiners located in the Houston and Texas City, Texas refining hub representing more than 2 MMBPD of refining capacity. The ECHO terminal will also have connections to marine facilities which will provide connectivity to any refinery on the U.S. Gulf Coast. The ECHO facility is scheduled to begin service in mid-2012 and will initially have 0.8 MMBbls of crude oil storage capacity. In February 2012, we announced an expansion of our ECHO facility, which will provide capability to increase its crude oil storage capacity to approximately 6 MMBbls.

Expansion of Our Propylene Fractionation Capacity at Mont Belvieu

To produce PGP, which is approximately 99.5% pure propylene, we fractionate refinery grade propylene (“RGP”), which is approximately 60% to 65% propylene, with the remainder being propane and butane. The demand for PGP primarily relates to the manufacture of polypropylene, which has a variety of end uses including packaging film, fiber for carpets and upholstery, and molded plastic parts for appliances, automotive, houseware and medical products. Since 2000, demand for PGP has increased by 20%; however, the supply of PGP produced as a co-product from the cracking of crude oil derivatives in the production of ethylene has declined approximately 40%. This decline is attributable to ethylene producers using more NGLs, such as ethane and propane, as feedstocks instead of more costly crude oil derivatives.

We have an extensive integrated propylene infrastructure system that complements the expansion project. Through our Texas City RGP Gathering System, which connects to 13 refineries in the Houston, Texas area, as well as marine, rail and truck transportation capabilities at our Mont Belvieu complex, we can receive supplies of RGP from approximately 60 facilities across North America. On the delivery side, we connect to 17 consumers of PGP. We also have the only operating PGP export terminal in the U.S. located in Seabrook, Texas. This export facility enables us to provide PGP to growing international markets.

Expansion of Our Houston Ship Channel Import/Export Terminal

propane and other NGLs to more than 10,000 barrels per hour, while enhancing the terminal’s ability to load multiple vessels simultaneously. We expect to complete this expansion project in the second half of 2012.

Expansion of Our Mid-America Pipeline System in the Rocky Mountains

In March 2011, we announced an expansion project involving the Rocky Mountain segment of our Mid-America Pipeline System. The 2,932-mile Rocky Mountain pipeline transports mixed NGLs from the Rocky Mountain Overthrust and San Juan Basin areas to our Hobbs NGL fractionation facility located in Gaines County, Texas. At the Hobbs facility, the Mid-America Pipeline System links to our Seminole Pipeline, which enables shippers access to the world’s largest NGL fractionation complex at Mont Belvieu, Texas, including facilities owned and operated by us.

The Rocky Mountain pipeline expansion involves looping the existing system with approximately 218 miles of 16-inch diameter pipeline, as well as pump station modifications. This expansion project is expected to add 62.5 MBPD of transportation capacity to the Rocky Mountain pipeline’s existing capacity of approximately 275 MBPD (after taking into account shipper commitments announced in January 2012). The additional capacity is designed to handle growing natural gas and NGL production from major supply basins in Utah, Colorado, Wyoming and New Mexico. Several new natural gas processing plants are being constructed in the Uinta, Piceance and Greater Green River basins that will fill the expansion, which is expected to begin service in the third quarter of 2014. Additionally, the Rocky Mountain expansion project complements our Texas Express Pipeline joint venture, and enhances the growth opportunities of our integrated processing, pipeline, storage, fractionation and distribution network.

Incident at Our Mont Belvieu West Storage Facility

General Outlook for 2012

Commercial Outlook

We provide midstream energy services to producers and consumers of natural gas, NGLs, crude oil, refined products and certain petrochemicals. Factors that can affect the demand for our products and services include global and U.S. economic conditions, the market price and demand for energy, the cost to develop natural gas and crude oil reserves in the U.S., and the cost and availability of capital to energy companies to invest in exploration and production activities.

The global economic expansion that began in late 2009 continued in 2011, with all of the twenty largest developed economies (“G20”), except for Japan, reporting year-over-year growth in real gross domestic product (“GDP”) for 2011. This growth appears to be continuing in early 2012. The U.S. reported modest year-over-year real GDP growth of 1.7% for 2011 compared to 2010. By comparison, the U.S. reported year-over-year real GDP growth of 3.0% for 2010 compared to 2009.

Global demand for petroleum products continues to increase at a rate, similar to that of global economic growth, which continues to benefit from the rate of growth in developing economies. However, in the U.S. and other Organization for Economic Co-operation and Development (“OECD”) countries, demand for petroleum products has declined slightly responding to higher prices, increased regulation, and improved technology. According to the U.S. Energy Information Administration, consumption of natural gas increased 3.7% for the first eleven months of 2011 versus the same period in 2010 primarily due to power generation requirements. Conversely, U.S. demand for petroleum products used for transportation purposes (e.g., motor gasoline, distillate and jet fuel) for the first eleven months of 2011 decreased by 1.7% compared to the same period of 2010.

As a result of increased global demand and geopolitical concerns, crude oil prices have continued to increase. The average prices of West Texas Intermediate (“WTI”) crude oil for 2009, 2010 and 2011 were $61.88, $79.53 and $95.12 per barrel, respectively. Crude oil futures for calendar year 2012 as quoted on the New York Mercantile Exchange (“NYMEX”) are currently $106.83 per barrel. In contrast, natural gas prices decreased from 2010 to 2011 primarily due to increasing shale gas production in the U.S., which has led to excess domestic natural gas supplies. For example, Henry Hub natural gas prices for 2009, 2010 and 2011 averaged $3.99, $4.39 and $4.04 per MMBtu, respectively. Henry Hub natural gas futures for calendar year 2012 as quoted on the NYMEX are currently $2.97 per MMBtu. Notably, the substantial change in the price relationship between natural gas and crude oil that began in 2009 has continued into 2012. In 2009, natural gas was priced at 37% of crude oil on an energy equivalent basis compared to 31% in 2010 and 24% in 2011. Based on NYMEX futures for 2012, natural gas is currently priced at approximately 16% relative to the price of crude oil on an energy equivalent basis.

As a result of the current relative prices of crude oil and NGLs compared to the price of natural gas, exploration and production companies are reallocating capital to increase drilling activities in shale and other non-conventional resource plays that produce crude oil and liquids-rich natural gas. Generally, producers are decreasing drilling activity in onshore areas that produce dry natural gas. This same trend is also occurring in the Gulf of Mexico, with producers investing capital to develop new sources of crude oil production rather than natural gas.

Natural gas and NGLs have had a significant feedstock price advantage over more costly crude oil derivatives (such as naphtha) and this trend is expected to continue based on prices currently quoted on the futures markets. This trend is primarily due to the following factors: (i) a decline in global crude oil excess production capacity; (ii) more government-held acreage being off limits to non-sovereign energy companies; (iii) geopolitical risk; (iv) growing demand for crude oil by China, India and other developing economies; (v) the globalization of international natural gas markets with more foreign-based liquefied natural gas liquefaction facilities becoming operational; (vi) technological breakthroughs in connection with shale resource plays in the U.S. that have decreased finding and development costs for natural gas, NGLs and crude oil; and (vii) the general inability to export natural gas from the U.S. Domestic energy producers and petrochemical companies are strategically repositioning their companies accordingly.

We believe this new trend in domestic energy production has led to a long-term structural change in feedstock selection by the domestic petrochemical industry, which is the largest consumer of NGLs. Lower feedstock costs have provided U.S. ethylene producers with a competitive global cost advantage, as ethylene crackers in Europe and Asia are mostly limited to using higher-priced naphtha feedstocks (which are priced more closely to crude oil). For 2009 through 2011, ethane and propane have been the most consistently profitable feedstocks in the production of ethylene, and are forecasted to remain so in 2012.

The production cost advantage enjoyed by U.S. petrochemical companies has led them to maximize their consumption of NGLs in the production of ethylene. Since 2009, many of these companies have expanded their operations in the U.S. and are continuing to build flexibility into their existing operations in order to increase their consumption of NGLs (as economically warranted). Even non-U.S. based ethylene crackers have responded to the NGL feedstock cost advantage by importing propane, including propane produced in the U.S., to displace crude oil derivatives such as naphtha as feedstock.

Per industry publications, domestic production of ethylene increased approximately 3.1% from 2010 to 2011. In 2011, the average ethane consumption of U.S. ethylene producers was approximately 934 MBPD, which represents an increase of 53 MBPD over 2010 levels, and we expect the trend to continue upward. According to

Table of Contents

recent industry publications, ethane demand by the domestic ethylene industry approximated 1 million barrels per day in December 2011. We believe the U.S. ethylene industry could consume approximately 250 MBPD of incremental ethane feedstocks over the next three years through modifications, expansions and debottlenecks of existing facilities. In addition, petrochemical companies have announced plans to construct additional world-scale ethylene plants in the U.S. in the coming years.

Strong end-user demand for NGLs and increases in liquids-rich natural gas production from developing shale plays such as the Eagle Ford, Uinta, Granite Wash, Marcellus and Utica Shales are expected to: (i) keep certain of our natural gas pipelines and processing plants and our NGL fractionators, pipelines, storage and export facilities operating at high utilization rates; (ii) provide attractive natural gas processing margins for our equity NGL production; and (iii) provide us with additional opportunities to invest capital to build new natural gas pipelines and processing facilities, NGL fractionation and pipeline facilities, and crude oil pipelines.

Henry Hub natural gas prices have significantly declined from a peak of over $13.00 per MMBtu in mid-2008 to less than $2.68 per MMBtu in February 2012. This price decrease has generally resulted in energy companies reallocating and, in some cases, reducing their drilling capital expenditure budgets. Natural gas drilling rig counts generally respond to changes in price and have moved down from a peak of 1,606 gas-directed rigs in 2008 to 919 at year end 2010, 809 at year end 2011 and approximately 720 in February 2012. Even though the total natural gas rig count has dropped from peak levels, the substantial efficiencies of horizontal drilling in the non-conventional and shale resource basins have allowed producers to maintain overall natural gas deliverability. As a result, rig count is not necessarily a reliable indicator of the level of future natural gas production or reserves. Because of the market prices of crude oil and NGLs, drilling activity is especially robust in shale plays containing crude oil, condensate and liquids-rich natural gas production such as the Eagle Ford, Granite Wash, Bakken and Marcellus Shales. Drilling activity in shale plays with dry natural gas production, such as the Haynesville/Bossier and Fayetteville, is down from peak levels, but remains active as certain producers are drilling to hold recently executed leases or have entered into joint ventures whereby their new joint venture partners are providing the capital to fund the development of the area for a certain period of time and for a certain dollar amount. In areas with conventional natural gas reserves, where producers typically have higher finding costs and leases are usually already held by production, rig counts generally remain significantly below peak levels.

Based on forecasted new drilling activity, the number of drilled wells waiting to be connected to our pipeline systems, and natural depletion of the associated resource basins, we believe the aggregate natural gas pipeline volumes transported on our Jonah Gathering System, Piceance Basin Gathering System and San Juan Gathering System for 2012 could range from an increase of 5% to a decrease of 5% compared to volumes transported in 2011. These areas have substantial, undeveloped non-conventional natural gas reserves (e.g., prospects to develop additional production horizons in these basins such as the Mancos and Niobrara Shales) with some of the lowest finding costs in the U.S. and are supported by existing pipeline infrastructure to transport the natural gas to market. We believe that as U.S. natural gas supply and demand becomes more balanced and natural gas prices become less volatile, these areas could experience an increase in drilling activity to support, and potentially increase, current production levels.

In the Eagle Ford Shale, which runs parallel to the Texas Gulf Coast and adjacent to our Texas Intrastate System, we have completed several pipeline projects that enable us to gather, transport and process approximately 900 MMcf/d of new natural gas production from the area. Generally, energy companies are continuing to have success in the Eagle Ford Shale and have indicated plans to accelerate their associated drilling programs. Production from this region includes crude oil, condensate, liquids-rich natural gas and dry natural gas. In 2010, we announced expansions of our natural gas pipeline, storage and processing facilities; NGL pipeline and fractionation facilities; and crude oil pipeline and storage facilities to facilitate production growth from this region. These projects represent approximately $3.0 to $3.5 billion of capital expenditures in the aggregate from 2010 through 2013.

Natural gas production from the Haynesville/Bossier Shale area of northern Louisiana has grown rapidly over the last three years and has the potential to grow even more over the next several years if natural gas prices show some recovery from their recent low levels. In November 2011, we completed construction and began commercial operations on our $1.5 billion Haynesville Extension of our Acadian Gas System. The Haynesville

Table of Contents

Extension is a 270-mile, 42-inch/36-inch pipeline designed to transport up to 1.8 Bcf/d of natural gas and is backed by 10-year firm fixed fee commitments from producers.

We estimate that natural gas and crude oil volumes handled by our offshore Gulf of Mexico assets will be slightly lower in 2012 compared to 2011 due to lower exploration and production activities that began in the second half of 2010 caused by federal regulatory uncertainty in the aftermath of the Deepwater Horizon oil spill. We believe crude oil volumes on our systems will increase from 2011 levels once drilling and development activities resume. Natural gas pipeline volumes may be slower to return to historical levels due to producers’ allocating their capital to develop crude oil plays rather than natural gas plays due to the relative prices of these commodities. We estimate average volumes on our largest offshore asset, the Independence Hub platform and Trail pipeline will range between 350 BBtus/d and 450 BBtus/d in 2012 compared to an average of 500 BBtus/d in 2011. For the first 60 months after the Independence Hub platform went into service in March 2007, the platform has been earning a monthly demand charge of $4.6 million. This 60-month period will expire in March 2012, and this monthly demand charge will terminate. Enterprise owns 80% of the Independence Hub platform.

Our refined products pipeline systems generally serve Petroleum Administration for Defense District (“PADD”) 2 of the U.S. Refinery production in PADD 2 increased by 66 MBPD in 2011 compared to 2010 due to the profit margin advantage that refiners in PADD 2 had relative to refiners on the U.S. Gulf Coast. This advantage resulted from PADD 2 refiners having the ability to utilize WTI-priced crude oil, which was priced at a substantial discount to crude oil used by refiners on the Gulf Coast (i.e., crude oil prices paid by Gulf Coast refiners are primarily based on international prices for crude oil).

Demand for refined products in PADD 2 for 2011 was approximately 4.4 MMBbls/d, which was a decrease of 1.9% compared to 2010. Our Products Pipeline System and Centennial Pipeline transport refined products produced by refineries on the Gulf Coast to be consumed in the PADD 2 region. As a result of the increased refinery production in PADD 2, demand to transport refined products to PADD 2 on our pipelines decreased. Throughput volumes to PADD 2 in 2011 on our refined products pipelines decreased by 116 MBPD to 301 MBPD. We do not expect a significant increase in demand for our refined products transportation services from the Gulf Coast to PADD 2 in 2012.

Price differentials between WTI and Brent crude oil were much wider than normal in 2011, as oil production from sources north of the Cushing hub in Oklahoma, including the Bakken Shale in North Dakota and the Canadian Oil Sands increased without adequate incremental pipeline capacity to transport them southward to markets along the Gulf Coast. These spreads reached as high as $27 per barrel in October 2011, but tightened after we and Enbridge announced their plans to reverse and expand the Seaway pipeline in November 2011 in order to move crude oil from the Midwest to the Gulf Coast. In addition to the planned Seaway pipeline reversal, a significant amount of rail capacity was added in 2011 in order to move crude southward from the producing areas and Cushing hub to refining centers. For additional information regarding the planned reversal of the Seaway pipeline, see “ — Significant Recent Developments—Plans with Enbridge to Reverse the Seaway Pipeline” within this Item 7 discussion.

Liquidity Outlook

The corporate debt and equity capital markets were generally accessible in 2011. Sovereign credit markets, however, continue to be volatile due to large budget deficits being incurred by the United States, United Kingdom and many developed European countries. The cost of our term debt and equity capital generally declined and the availability of term debt and equity capital improved. Likewise, the general availability of credit commitments from most banks also improved from a year ago, except for certain investment banks and European banks, which are being impacted by their cost of capital and sovereign debt concerns.

At December 31, 2011, we had $3.37 billion of consolidated liquidity, which is defined as unrestricted cash on hand plus borrowing capacity available under our $3.5 Billion Multi-Year Revolving Credit Facility. In January 2012, we sold 22,762,636 common units of Energy Transfer Equity in a private transaction, which generated cash proceeds of approximately $825.1 million. In February 2012, we paid a quarterly cash distribution of $530.4 million to unitholders with respect to the fourth quarter of 2011. Also in February 2012, EPO issued $750.0 million in principal amount of 30-year unsecured Senior Notes EE. Net proceeds from the issuance of Senior Notes EE were

Table of Contents

used to temporarily reduce borrowings outstanding under EPO’s $3.5 Billion Multi-Year Revolving Credit Facility (which was used to repay at maturity its $490.5 million principal amount of Senior Notes S due February 2012 and $9.5 million principal amount of TEPPCO Senior Notes due February 2012 prior to the delivery of Senior Notes EE) and for general company purposes. We currently estimate that our capital expenditures for 2011 will approximate $3.8 billion, which includes approximately $3.5 billion for growth capital projects and $315 million for sustaining capital expenditures. Based on current market conditions, 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.

In January 2012, Standard & Poor’s upgraded its corporate credit rating of EPO from BBB- to BBB, while maintaining its outlook for EPO’s business as “positive.” Moody’s Investor Services (“Moody’s”) did likewise, upgrading its credit rating of EPO from Baa3 to Baa2 and reaffirming that its outlook for EPO’s business remained “positive.” In February 2012, Fitch Ratings upgraded its corporate credit rating of EPO to BBB while maintaining its outlook for EPO’s business as “stable.” Based on information currently available to us, we believe we will maintain the aforementioned credit ratings and meet our loan covenant obligations in 2012.

As of the date of this report, we have approximately $2.85 billion of senior notes maturing in the period beginning 2012 through the end of 2014. The U.S. government is expected to run substantial annual budget deficits (exceeding a trillion dollars each year) that will require a corresponding issuance of debt by the U.S. Treasury from 2012 through 2014. The interest rate on U.S. Treasury debt has a direct impact on the cost of our debt. At this time, we are uncertain what the impact of the expected large issuances of U.S. Treasury debt and the prevailing economic and capital market conditions during these future periods will have on the cost and availability of capital. We have executed approximately $1.35 billion of interest rate swaps to hedge a portion of our expected future debt issuances in connection with the refinancing of our debt that matures during the 2012 through 2013 time period. We will continue to monitor and evaluate the condition of the capital markets and interest rate risk with respect to refinancing these maturities and funding our capital expenditures.

Basis of Financial Statement Presentation

In accordance with rules and regulations of the Securities and Exchange Commission (“SEC”) and various other accounting standard-setting organizations, our general purpose financial statements reflect the consolidation of financial information of businesses that we control. Our general purpose Consolidated Financial Statements present those investments over which we do not have control as unconsolidated affiliates (e.g., our equity method

Table of Contents

investment in Energy Transfer Equity). Noncontrolling interest reflects third party and related party ownership of our consolidated subsidiaries.

Prior to the Holdings Merger, Enterprise was a consolidated subsidiary of Holdings, which was Enterprise’s parent. Upon completion of the Holdings Merger, Holdings merged with and into a wholly owned subsidiary of Enterprise. The Holdings Merger resulted in Holdings being considered the surviving consolidated entity for accounting purposes, while Enterprise Products Partners L.P. is the surviving consolidated entity for legal and reporting purposes. For accounting purposes, Holdings is deemed the acquirer of the noncontrolling interests in Enterprise that were previously recognized in Holdings’ consolidated financial statements (i.e., the acquisition of Enterprise’s limited partner interests that were owned by parties other than Holdings).

As a result of the Holdings Merger, Enterprise’s consolidated financial and operating results prior to November 22, 2010 have been presented as if Enterprise were Holdings from an accounting perspective (i.e., the financial statements of Holdings became the historical financial statements of Enterprise). While it was a publicly traded partnership, Holdings (NYSE, ticker symbol “EPE”) electronically filed its annual and quarterly consolidated financial statements with the SEC. You can access this information at www.sec.gov .

The primary differences between Holdings’ and Enterprise’s consolidated results of operations were (i) general and administrative costs incurred by Holdings and EPGP (our former general partner); (ii) equity in income of Holdings’ noncontrolling ownership interests in Energy Transfer Equity; and (iii) interest expense associated with Holdings’ debt. In addition, for periods prior to November 22, 2010, the net assets, income, cash distributions and contributions and other amounts attributable to Enterprise’s limited partner interests that were owned by third parties and related parties other than Holdings are presented as a component of noncontrolling interests. See Note 13 of the Notes to Consolidated Financial Statements included under Item 8 of this annual report for additional information regarding our noncontrolling interests.

Historical limited partner units outstanding and earnings per unit amounts presented in our financial statements have been retroactively presented in connection with the 1.5 to one unit-for-unit exchange that occurred under the Holdings Merger. See Note 17 of the Notes to Consolidated Financial Statements included under Item 8 of this annual report for additional information regarding earnings per unit.

Since we historically consolidated Duncan Energy Partners for financial reporting purposes, the Duncan Merger did not change the basis of presentation of our historical financial statements.

Comparison of 2011 with 2010

Revenues for 2011 were $44.31 billion compared to $33.74 billion for 2010, a $10.57 billion year-to-year increase. Consolidated revenues from sales of NGLs and related products increased $3.28 billion year-to-year primarily due to higher sales prices in 2011 compared to 2010. Revenues from sales of natural gas decreased $62.4 million year-to-year due to lower sales prices. Crude oil sales revenues increased $5.25 billion year-to-year due to higher sales prices and volumes. Consolidated revenues from sales of petrochemicals and refined products increased $1.99 billion year-to-year primarily due to higher propylene and refined products sales prices in 2011 compared to 2010. Consolidated revenues from other midstream services increased $117.3 million year-to-year primarily due to positive variances of $171.2 million related to the timing of the State Line and Fairplay acquisitions in May 2010 and our acquisition of a trucking business from EPCO in September 2010 (i.e., 2010 includes only a partial year of revenues from these acquired businesses) and $64.9 million related to the start of commercial operations on newly constructed assets such as the Haynesville Extension of our Acadian Gas System in November 2011. Collectively, the remainder of our consolidated revenues from other midstream services decreased $118.8 million year-to-year largely due to a decrease in throughput volumes on our Products Pipeline System and pipeline and platform assets offshore in the Gulf of Mexico.

Operating costs and expenses were $41.32 billion for 2011 compared to $31.45 billion for 2010, a $9.87 billion year-to-year increase. Cost of sales related to our marketing activities increased $8.20 billion year-to-year primarily due to higher crude oil sales volumes and, with the exception of natural gas, higher energy commodity prices. The operating costs and expenses of our natural gas processing plants increased $1.38 billion year-to-year primarily due to (i) an increase in plant thermal reduction (“PTR”) costs attributable to higher natural gas processing volumes and (ii) higher NGL prices during 2011 relative to 2010. In general, higher NGL prices result in increased operating costs associated with percent-of-proceeds and margin band types of natural gas processing contracts.

Table of Contents

Consolidated operating costs and expenses also increased $160.6 million year-to-year due to the timing of the State Line and Fairplay acquisitions in May 2010 and our acquisition of a trucking business from EPCO in September 2010 (i.e., 2010 includes only a partial year of operating costs from these acquired businesses). Operating costs and expenses for the remainder of our midstream services increased $195.0 million year-to-year primarily due to higher maintenance and pipeline integrity expenses we incurred in 2011 compared to 2010 and operating costs associated with assets we constructed and placed into service in 2011, including our Haynesville Extension and new Mont Belvieu NGL fractionator.

Depreciation, amortization and accretion expenses included in operating costs and expenses increased $22.4 million year-to-year primarily due to depreciation expense recorded in connection with newly constructed assets being placed into service in mid-year 2010 and in 2011 and depreciation and amortization expense recorded in connection with assets acquired as a result of business combinations in mid-2010. We recorded $27.8 million of non-cash asset impairment charges in 2011 compared to $8.4 million of such charges during 2010. The $19.4 million increase in impairment charges primarily relates to write-downs of spare parts inventory and certain storage cavern assets. Gains from asset sales and related transactions included in operating costs and expenses increased $111.6 million year-to-year primarily due to a $129.1 million gain we recorded as a result of the sale of Crystal to Boardwalk that closed in December 2011.

Changes in our revenues and operating costs and expenses year-to-year are explained in part by changes in energy commodity prices. The weighted-average indicative market price for NGLs was $1.46 per gallon during 2011 versus $1.16 per gallon during 2010 – a 26% year-to-year increase. Our determination of the weighted-average indicative market price for NGLs is based on U.S. Gulf Coast prices for such products at Mont Belvieu, Texas, which is the primary industry hub for domestic NGL production. The market price of natural gas (as measured at Henry Hub in Louisiana) averaged $4.04 per MMBtu during 2011 versus $4.39 per MMBtu during 2010. The market price of crude oil (as measured on the NYMEX) averaged $95.12 per barrel during 2011 compared to $79.53 per barrel during 2010 – a 20% year-to-year increase. See “Selected Price and Volumetric Data” included within this Item 7 for additional historical energy commodity pricing information.

General and administrative costs were $181.8 million for 2011 compared to $204.8 million for 2010, a $23.0 million year-to-year decrease. General and administrative costs for 2011 include transaction expenses of $12.0 million related to the Duncan Merger and $2.9 million related to the sale of Crystal. General and administrative costs for 2010 include $20.2 million of expenses related to the Employee Partnership liquidations and $24.5 million of transaction expenses related to the Holdings Merger. Collectively, the remainder of our general and administrative costs increased $6.8 million year-to-year primarily due to higher employee compensation, office rent and depreciation expenses in 2011 compared to 2010.

Equity income from our unconsolidated affiliates was $46.4 million for 2011 compared to $62.0 million for 2010, a $15.6 million year-to-year decrease. Collectively, equity earnings from Seaway, Centennial Pipeline LLC (“Centennial”) and our investees operating in the Gulf of Mexico decreased $38.1 million year-to-year primarily due to lower pipeline throughput volumes in 2011 compared to 2010. Equity earnings from Energy Transfer Equity increased $17.6 million year-to-year. Equity earnings from our investment in Venice Energy Service Company, L.L.C. (“VESCO”) increased $6.7 million year-to-year primarily due to higher natural gas processing volumes and margins in 2011 compared to 2010. Collectively, equity earnings from our other equity method investees decreased $1.8 million year-to-year.

Operating income for 2011 was $2.86 billion compared to $2.15 billion for 2010. Collectively, the changes in revenues, costs and expenses and equity income described above resulted in the $711.9 million year-to-year increase in operating income.

Consolidated interest expense increased $2.2 million year-to-year to $744.1 million in 2011 compared to $741.9 million in 2010. In general, interest expense represents that portion of borrowing costs (e.g., interest payments) that are not capitalized in connection with the funding of capital expenditures. Borrowing costs attributable to the funding of construction projects are capitalized until the related asset is placed in service, at which time the associated interest costs are then reflected as interest expense. Any borrowing costs that had been capitalized are expensed as a component of depreciation when the related fixed asset is placed into service. Interest expense also includes the amortization of debt issuance costs and the effects of interest rate hedging activities.

Table of Contents

Although our average debt principal balances increased from $13.23 billion in 2010 to $14.59 billion in 2011, a substantial portion of the costs associated with the new borrowings were capitalized in connection with our capital spending program. Capitalized interest increased $59.5 million year-to-year to $106.7 million for 2011 from $47.2 million for 2010. Our consolidated interest expense amounts are directly impacted by changes in the weighted-average fixed and variable interest rates charged under our debt agreements. On average, interest rates continued to decrease over the last year. For example, as we refinanced the maturities of our fixed rate senior notes, the rates we obtained on the new debt issuances were lower than those associated with the debt being refinanced. However, as interest rates declined certain of our interest rate hedges partially mitigated the benefit of lower rates on the higher debt balances.

Consolidated net income increased $704.6 million year-to-year to $2.09 billion for 2011 from $1.38 billion for 2010. Net income attributable to noncontrolling interests was $41.4 million for 2011 compared to $1.06 billion for 2010, which included $1.0 billion attributable to the limited partners of Enterprise other than Holdings. For periods prior to the Holdings Merger, that portion of Enterprise’s net income attributable to its limited partner interests owned by third parties and related parties other than Holdings is presented as a component of net income attributable to noncontrolling interests. See Note 13 of the Notes to Consolidated Financial Statements included under Item 8 of this annual report for additional information regarding our net income attributable to noncontrolling interests. Net income attributable to partners increased $1.73 billion year-to-year to $2.05 billion for 2011 from $320.8 million for 2010.

The following information highlights significant year-to-year variances in gross operating margin by business segment:

NGL Pipelines & Services . Gross operating margin from this business segment was $2.18 billion for 2011 compared to $1.73 billion for 2010, a $451.6 million year-to-year increase. Gross operating margin for 2011 includes $4.3 million of gains related to cash proceeds from business interruption insurance claims. The following paragraphs provide a discussion of segment results excluding gains from business interruption insurance claims.

Gross operating margin from our natural gas processing and related NGL marketing business was $1.32 billion for 2011 compared to $989.9 million for 2010, a $331.6 million year-to-year increase. Gross operating margin from our NGL marketing activities increased $210.6 million year-to-year due to higher sales margins. Gross operating margin from our natural gas processing plants located in the Rocky Mountains increased $71.7 million year-to-year primarily due to higher natural gas processing margins and higher equity NGL production and fee-based processing volumes during 2011 compared to 2010. Collectively, gross operating margin from our natural gas processing facilities in southern Louisiana and the San Juan and Permian Basins increased $42.4 million year-to-year primarily due to higher natural gas processing margins during 2011 compared to 2010. Results from our facilities in southern Louisiana include a $6.7 million year-to-year increase in equity earnings from our investment in VESCO. Natural gas processing activities on the Fairplay gathering system, which we acquired in May 2010, contributed $8.9 million of the year-to-year increase in gross operating margin.

Gross operating margin from our NGL pipelines and related storage business was $638.4 million for 2011 compared to $604.8 million for 2010, a $33.6 million year-to-year increase. Total NGL transportation volumes decreased to 2,284 MBPD during 2011 from 2,322 MBPD during 2010. Gross operating margin from our Mid-America Pipeline System, Seminole Pipeline and related NGL terminals increased $53.0 million year-to-year primarily due to an increase in revenues attributable to changes in the mix of transportation services provided to customers (e.g., increased long-haul delivery volumes and changes in delivery destinations) during 2011 compared to 2010 and an increase in system-wide tariffs in July 2011. Gross operating margin from our NGL storage activities increased $14.9 million year-to-year primarily due to an increase in storage and terminaling fees charged at our NGL terminals in the northeastern U.S. Gross operating margin from our South Texas NGL System increased $5.0 million year-to-year primarily due to a $6.8 million charge we recorded during 2010 related to a dispute involving a pipeline segment on this system.

Collectively, gross operating margin from our NGL pipelines in southern Louisiana decreased $18.5 million year-to-year primarily due to a 25 MBPD decrease in transportation volumes. The year-to-year decrease in NGL transportation volumes on our pipelines in southern Louisiana is primarily due to reduced supplies of NGLs during 2011 compared to 2010 from offshore production in the Gulf of Mexico and reduced volumes of mixed

Table of Contents

NGLs transported from our facility in Mont Belvieu, Texas to NGL fractionators in southern Louisiana. Gross operating margin from our Dixie Pipeline and related NGL terminals decreased $13.7 million year-to-year primarily due to a 20 MBPD decrease in transportation volumes and higher pipeline integrity expenses during 2011. Downtime in connection with pipeline integrity projects we completed on the Dixie Pipeline during 2011 and warmer weather during the winter months of 2011 compared to the same period in 2010 both contributed to the year-to-year decrease in transportation volumes. Gross operating margin from our Houston Ship Channel import/export terminal and a related pipeline decreased $9.2 million year-to-year primarily due to higher operating expenses during 2011 compared to 2010.

Gross operating margin from our NGL fractionation business was $220.0 million for 2011 compared to $137.9 million for 2010, an $82.1 million year-to-year increase. Our NGL fractionation volumes were 575 MBPD during 2011 compared to 485 MBPD during 2010. Gross operating margin from our Mont Belvieu NGL fractionators increased $62.9 million year-to-year primarily due to higher NGL fractionation volumes and fees. During the fourth quarter of 2010, we placed into service a fourth NGL fractionator at our complex in Mont Belvieu, Texas. We completed a fifth NGL fractionator at our Mont Belvieu complex and placed it into service during the fourth quarter of 2011. Collectively, our new NGL fractionators in Mont Belvieu added more than 150 MBPD of NGL fractionation capacity at this key industry hub. Gross operating margin from our Norco NGL fractionator increased $17.3 million year-to-year primarily due to higher NGL prices, which resulted in higher revenues associated with percent-of-liquids contracts and product blending activities during 2011 compared to 2010. Gross operating margin from our Hobbs NGL fractionator increased $8.4 million year-to-year primarily due to higher NGL fractionation volumes and fees. Gross operating margin from our Colorado NGL fractionators, which we sold during March 2011, decreased $4.9 million year-to-year.

Onshore Natural Gas Pipelines & Services . Gross operating margin from this business segment was $675.3 million for 2011 compared to $527.2 million for 2010, a $148.1 million year-to-year increase. Onshore natural gas transportation volumes were 13.23 TBtus/d during 2011 compared to 11.48 TBtus/d during 2010.

Gross operating margin from our onshore natural gas pipelines and related marketing business was $633.1 million for 2011 compared to $471.7 million for 2010, a $161.4 million year-to-year increase. Gross operating margin from our natural gas marketing activities increased $50.7 million year-to-year primarily due to higher sales volumes and margins. Gross operating margin from our Texas Intrastate System increased $62.9 million year-to-year primarily due to higher firm capacity reservation revenues and a 280 BBtus/d year-to-year increase in natural gas throughput volumes. Increased natural gas production volumes from the Eagle Ford Shale supply basin resulted in stronger demand for our natural gas transportation services during 2011 compared to 2010. The year-to-year increase in transportation volumes on our Texas Intrastate System was also due to greater demand from gas-fired electric generation utilities as a result of record heat in Texas during the summer months of 2011. Gross operating margin from our Acadian Gas System increased $29.3 million year-to-year primarily due to revenues earned by our Haynesville Extension pipeline. The Haynesville Extension of our Acadian Gas System commenced operations in November 2011 and transported 1.22 TBtus/d of natural gas during the fourth quarter of 2011. Our State Line and Fairplay natural gas gathering systems, which we acquired in May 2010, contributed $26.5 million of the year-to-year increase in gross operating margin. Gross operating margin from our Piceance Basin Gathering System increased $6.7 million year-to-year primarily due to a 195 BBtu/d increase in transportation volumes. Gross operating margin from our Jonah Gathering System decreased $14.4 million year-to-year on a 137 BBtu/d decrease in transportation volumes.

Gross operating margin from our natural gas storage business was $42.2 million for 2011 compared to $55.5 million for 2010, a $13.3 million year-to-year decrease. In December 2011, we sold our natural gas storage facilities located near Petal and Hattiesburg, Mississippi. For additional information regarding the sale of these facilities, see “Significant Recent Developments—Sale of Our Mississippi Natural Gas Storage Facilities” within this Item 7.

Onshore Crude Oil Pipelines & Services . Gross operating margin from this business segment was $234.0 million for 2011 compared to $113.7 million for 2010, a $120.3 million year-to-year increase. Our onshore crude oil transportation volumes increased to 678 MBPD during 2011 from 670 MBPD during 2010. Gross operating margin from our crude oil marketing and related activities increased $96.2 million year-to-year primarily due to higher sales volumes and margins. Our crude oil marketing activities benefited from increased crude oil production

Table of Contents

volumes from supply basins in the Eagle Ford Shale, Barnett Shale, West Texas and Rocky Mountains. Collectively, gross operating margin from our South Texas System, West Texas System, Red River System and Basin Pipeline System increased $34.1 million year-to-year primarily due to a 46 MBPD increase in throughput volumes and higher average fees during 2011.

Equity earnings from our investment in Seaway decreased $10.8 million year-to-year primarily due to lower volumes delivered to the Cushing hub from the Texas Gulf Coast during 2011 compared to 2010. Net to our interest, throughput volumes on the Seaway pipeline system decreased 37 MBPD year-to-year. As a result of an oversupply of crude oil at the Cushing hub, crude oil in Cushing, Oklahoma is priced at a substantial discount to oil markets on the Gulf Coast. This has led refiners in the Midwest to source a significant amount of their crude oil feedstocks from the Cushing hub rather than shipping such volumes northward from the Gulf Coast (e.g., by using the Seaway pipeline). See “Significant Recent Developments—Plans with Enbridge to Reverse the Seaway Pipeline” within this Item 7, for information regarding a project to reverse the direction of crude oil flows on the Seaway pipeline to enable it to transport oil from the oversupplied Cushing hub to U.S. Gulf Coast refiners.

Offshore Pipelines & Services . Gross operating margin from this business segment was $228.2 million for 2011 compared to $297.8 million for 2010, a $69.6 million year-to-year decrease. Results for 2010 include $27.5 million of gains related to insurance proceeds. Excluding gains from insurance proceeds, gross operating margin from this business segment decreased $42.1 million year-to-year primarily due to the effects of last year’s federal offshore drilling moratorium and the ongoing deliberations of federal authorities to approve drilling and well workover permits. Although crude oil and natural gas drilling activity has resumed on a limited basis since last year’s drilling moratorium (which was in effect from May 2010 to October 2010), certain of our offshore pipeline and platform assets continue to experience reduced throughput volumes as existing wells experience natural production declines. We expect that drilling activity in the Gulf of Mexico will increase in the future as federal agencies allow exploration and production companies to proceed with the drilling of new wells. For additional information regarding the federal offshore drilling moratorium, see “—Additional regulations that cause delays or deter new offshore oil and gas drilling could have a material adverse effect on our financial position, results of operations and cash flows” on page 55 under Item 1A of this annual report.

Gross operating margin from our offshore crude oil pipeline business was $77.4 million for 2011 compared to $97.9 million for 2010, a $20.5 million year-to-year decrease. Our offshore crude oil transportation volumes averaged 279 MBPD during 2011 compared to 320 MBPD during 2010. Collectively, equity earnings from our investments in Poseidon Oil Pipeline Company, L.L.C. (“Poseidon”) and Cameron Highway Oil Pipeline Company (“Cameron Highway”) decreased $16.3 million year-to-year primarily due to lower throughput volumes. Net to our interest, crude oil throughput volumes on the Poseidon and Cameron Highway pipelines decreased 39 MBPD year-to-year. Collectively, gross operating margin from our Shenzi and Constitution Oil Pipelines decreased $4.9 million year-to-year on a 13 MBPD decrease in throughput volumes.

Gross operating margin from our offshore natural gas pipeline business was $40.8 million for 2011 compared to $45.5 million for 2010, a $4.7 million year-to-year decrease. Our offshore natural gas transportation volumes were 1,065 BBtus/d during 2011 versus 1,242 BBtus/d during 2010. Gross operating margin from our Independence Trail pipeline decreased $12.0 million year-to-year primarily due to lower transportation volumes. Natural gas transportation volumes on our Independence Trail pipeline decreased to 461 BBtus/d during 2011 from 576 BBtus/d during 2010 as a result of lower volumes from the Independence Hub platform (see below). Gross operating margin from our High Island Offshore System decreased $4.8 million year-to-year primarily due to a decrease in volumes and 2010 included $4.2 million of revenues attributable to a rate case settlement. Gross operating margin from our Anaconda system increased $6.8 million year-to-year primarily due to a system extension we completed and placed into service during the third quarter of 2011. Collectively, gross operating margin from the remainder of our offshore natural gas pipeline business increased $5.3 million year-to-year primarily due to lower operating expenses on our Viosca Knoll Gathering System during 2011 compared to 2010.

Gross operating margin from our offshore platform services business was $110.0 million for 2011 compared to $126.9 million for 2010, a $16.9 million year-to-year decrease. On a net basis to our interest, platform natural gas processing volumes were 405 MMcf/d during 2011 compared to 513 MMcf/d during 2010. Gross operating margin from our Independence Hub platform decreased $10.0 million year-to-year primarily due to lower natural gas processing volumes as a result of depletion at existing production wells, the watering-out of certain wells

Table of Contents

and the lingering impact of the federal offshore drilling moratorium which has slowed the drilling of new wells. Gross operating margin from the remainder of our offshore platforms decreased $6.9 million year-to-year primarily due to lower natural gas processing volumes and higher maintenance expenses at our offshore platforms in the Garden Banks area of the Gulf of Mexico.

Petrochemical & Refined Products Services . Gross operating margin from this business segment was $535.2 million for 2011 compared to $584.5 million for 2010, a $49.3 million year-to-year decrease.

Gross operating margin from propylene fractionation and related activities was $161.2 million for 2011 compared to $212.4 million for 2010, a $51.2 million year-to-year decrease. Propylene fractionation volumes were 73 MBPD during 2011 compared to 77 MBPD during 2010. The year-to-year decrease in gross operating margin is primarily due to lower propylene fractionation volumes and sales margins during 2011 compared to 2010. Results for 2010 benefited from the combined effects of high demand for propylene and reduced propylene production from third party petrochemical facilities.

Gross operating margin from butane isomerization was $124.9 million for 2011 compared to $84.9 million for 2010, a $40.0 million year-to-year increase. Butane isomerization volumes increased to 101 MBPD during 2011 from 89 MBPD during 2010. The year-to-year increase in gross operating margin is primarily due to higher isomerization volumes and increased by-product production and associated sales margins.

Gross operating margin from octane enhancement and HPIB production was $109.1 million for 2011 compared to $47.0 million for 2010, a $62.1 million year-to-year increase. Gross operating margin from our octane enhancement facility in Mont Belvieu, Texas increased $54.7 million year-to-year primarily due to higher motor gasoline additive sales volumes and margins during 2011 compared to 2010. The remainder of the year-to-year increase is attributable to the addition of gross operating margin from recently acquired assets.

Gross operating margin from refined products pipelines and related activities was $79.6 million for 2011 compared to $170.8 million for 2010, a $91.2 million year-to-year decrease. Pipeline transportation volumes for the refined products business decreased to 642 MBPD during 2011 from 734 MBPD during 2010. Gross operating margin from our Products Pipeline System decreased $69.8 million year-to-year primarily due to lower throughput volumes and higher operating expenses during 2011 compared to 2010. Equity earnings from our investment in Centennial decreased $9.6 million year-to-year primarily due to lower transportation volumes. Net to our interest, transportation volumes on the Centennial pipeline decreased 22 MBPD year-to-year. Structural shifts in population, reduced demand and increased refinery production in the Midwest have contributed to a decline in demand for the transportation of refined products from the Gulf Coast to the Midwest. Gross operating margin from the marketing of refined products decreased $12.3 million year-to-year primarily due to lower sales margins associated with forward sales contracts.

Of the total year-to-year decrease in gross operating margin from the Products Pipeline System, we estimate that $13.7 million is due to higher operating expenses attributable to the impact of a pipeline leak that occurred in New York State in the third quarter of 2010. Following our repair of the leak, the affected segment of pipe was tested and returned to service in February 2011. In addition, results from our Products Pipeline System for 2011 include $9.1 million of operating expenses related to environmental remediation efforts and pipeline repairs following pipeline leaks that occurred in Texas and Louisiana. The remaining $47.0 million year-to-year decrease in gross operating margin from our Products Pipeline System is primarily due to lower volumes delivered to Northeast U.S. markets and higher operating costs such as expenses for maintenance and pipeline integrity projects.

Gross operating margin from marine transportation and other segment services was $60.4 million for 2011 compared to $69.4 million for 2010, a $9.0 million year-to-year decrease. Gross operating margin from marine transportation decreased $14.4 million year-to-year primarily due to lower revenues resulting from our sale of marine transportation vessels in February 2011 that comprised our former bunker fuel transportation fleet. Gross operating margin from other services increased $5.4 million year-to-year primarily due to our acquisition of truck transport operations from EPCO in September 2010.

Comparison of 2010 with 2009

Revenues for 2010 were $33.74 billion compared to $25.51 billion for 2009, an $8.23 billion year-to-year increase. Higher energy commodity sales prices and volumes during 2010 compared to 2009 resulted in a $7.99 billion year-to-year increase in consolidated revenues from the sale of NGLs, natural gas, crude oil and petrochemical and refined products. Consolidated revenues from sales of NGLs and related products increased $1.85 billion year-to-year primarily due to higher sales prices in 2010 compared to 2009. Revenues from sales of natural gas increased $518.3 million year-to-year due to higher sales prices and volumes. Crude oil sales revenues increased $3.6 billion year-to-year primarily due to higher sales prices. Consolidated revenues from sales of other petrochemical and refined products increased $2.02 billion year-to-year primarily due to (i) higher petrochemical and refined products sales volumes and (ii) higher propylene sales prices during 2010 compared to 2009. Collectively, the remainder of our consolidated revenues increased $240.1 million year-to-year primarily due to revenues generated from businesses we acquired or assets we constructed, principally the State Line and Fairplay natural gas gathering systems we acquired in May 2010 and a trucking business we acquired from EPCO in September 2010.

Operating costs and expenses were $31.45 billion for 2010 compared to $23.57 billion for 2009, a $7.88 billion year-to-year increase. The cost of sales related to our marketing activities increased $7.23 billion year-to-year primarily due to higher energy commodity prices and sales volumes. The operating costs and expenses of our natural gas processing plants increased $493.6 million year-to-year primarily due to higher PTR costs attributable to an increase in natural gas prices and processing volumes. Operating costs and expenses for 2010 include approximately $174.3 million attributable to business acquisitions and the placing in service of newly constructed assets during the year. Operating costs and expenses for 2009 include aggregate charges of $135.3 million related to our dissociation from the Texas Offshore Port System partnership (“TOPS”) and $28.7 million of expenses incurred by TEPPCO in connection with its river terminal business.

Depreciation, amortization and accretion expenses included in operating costs and expenses increased $127.0 million year-to-year primarily due to an increase in depreciation and amortization expense attributable to assets acquired in connection with business acquisitions in 2010 and the placing in service of newly constructed assets during 2010. We recorded $8.4 million of non-cash asset impairment charges during 2010 compared to $33.5 million of charges during 2009, a $25.1 million year-to-year decrease. Non-cash impairment charges recorded in 2009 include $22.8 million of expense incurred by TEPPCO related to its refined products terminals. Gains from asset sales and related transactions included in operating costs and expenses increased $44.4 million year-to-year primarily due to $56.6 million gains recorded in connection with our disposition of certain offshore assets in 2010.

General and administrative costs were $204.8 million for 2010 compared to $182.8 million for 2009, a $22.0 million year-to-year increase. General and administrative costs for 2010 include $20.2 million of expense related to the Employee Partnership liquidations and $24.5 million of transaction expenses related to the Holdings Merger. General and administrative costs for 2009 include $31.0 million of transaction expenses related to the TEPPCO Merger. Collectively, the remainder of our general and administrative costs increased $8.3 million year-to-year primarily due to higher expenses for director compensation and legal and tax professional services.

Table of Contents

Equity income from our unconsolidated affiliates was $62.0 million for 2010 compared to $92.3 million for 2009. The $30.3 million year-to-year decrease is primarily due to a $43.9 million decrease in equity earnings from Energy Transfer Equity, partially offset by improved results from our investments in midstream energy companies operating in Gulf of Mexico and higher earnings from K/D/S Promix, L.L.C. (“Promix”) and Centennial.

Operating income for 2010 was $2.15 billion compared to $1.85 billion for 2009. Collectively, the changes in revenues, costs and expenses and equity income described above resulted in the $292.6 million year-to-year increase in operating income.

Interest expense increased to $741.9 million for 2010 from $687.3 million for 2009, a $54.6 million year-to-year increase. Interest expense for 2010 includes $31.0 million of charges related to Holdings’ interest rate swaps and the write-off of Holdings’ unamortized debt issuance costs. The remainder of the increase in interest expense is primarily due to EPO’s issuance of Senior Notes Q and R during October 2009 and Senior Notes X, Y and Z in May 2010. Our average debt principal balance increased to $13.23 billion during 2010 from $13.0 billion during 2009.

As a result of items noted in the previous paragraphs, our consolidated net income increased $243.4 million year-to-year to $1.38 billion for 2010 compared to $1.14 billion for 2009. Net income attributable to noncontrolling interests was $1.06 billion for 2010 compared to $936.2 million for 2009. See Note 13 of the Notes to Consolidated Financial Statements included under Item 8 of this annual report for additional information regarding our net income attributable to noncontrolling interests. Net income attributable to partners increased $116.7 million year-to-year to $320.8 million for 2010 compared to $204.1 million for 2009.

The following information highlights significant year-to-year variances in gross operating margin by business segment:

NGL Pipelines & Services . Gross operating margin from this business segment was $1.73 billion for 2010 compared to $1.63 billion for 2009, a $103.9 million year-to-year increase. Gross operating margin for 2009 includes $5.9 million of gains related to insurance proceeds. The following paragraphs provide a discussion of segment results excluding gains from insurance proceeds.

Gross operating margin from our natural gas processing and related NGL marketing business was $989.9 million for 2010 compared to $947.9 million for 2009, a $42.0 million year-to-year increase. Equity NGL production increased to 121 MBPD during 2010 from 117 MBPD during 2009. Our Rocky Mountains natural gas processing plants contributed $31.6 million of the year-to-year increase in gross operating margin primarily due to increased equity NGL production. Gross operating margin from our natural gas processing activities in Texas increased $16.4 million year-to-year due to higher volumes and processing margins, which includes $9.8 million of gross operating margin attributable to natural gas processing activities on the Fairplay system that we acquired in May 2010. Gross operating margin from our NGL marketing activities increased $4.5 million year-to-year due to higher sales volumes and margins. Collectively, gross operating margin from the remainder of our natural gas processing activities decreased $10.5 million year-to-year primarily due to lower natural gas processing margins and fee-based processing volumes in at our plants in southern Louisiana and the San Juan and Permian Basins.

Gross operating margin from our NGL pipelines and related storage business was $604.8 million for 2010 compared to $538.9 million for 2009, a $65.9 million year-to-year increase. Total NGL transportation volumes increased to 2,322 MBPD during 2010 from 2,196 MBPD during 2009. Collectively, gross operating margin from our Louisiana NGL pipelines and Dixie Pipeline increased $55.7 million year-to-year primarily due to a 50 MBPD increase in throughput volumes and an increase in certain fees. Gross operating margin from our Houston Ship Channel import/export terminal and a related pipeline increased $17.6 million year-to-year primarily due to a 46 MBPD year-to-year increase in volumes. Gross operating margin from our storage and related terminal businesses increased $29.1 million year-to-year primarily due to higher storage volumes and fees, with our Mont Belvieu storage facility contributing $12.7 million of this increase. In addition, gross operating margin from our Rio Grande pipeline, which we acquired in the fourth quarter of 2009, increased $5.3 million year-to-year. Improved results from these assets were partially offset by a combined $39.2 million decrease in gross operating margin from our Mid-America Pipeline System, Seminole Pipeline and related terminals attributable to a $29.2 million benefit recorded for the Mid-America Pipeline System in 2009 related to a rate case settlement, a combined 16 MBPD decrease in throughput volumes on these systems and higher operating expenses. Gross operating margin from our

Table of Contents

remaining NGL pipelines decreased $2.6 million year-to-year primarily due to a $6.8 million charge we recorded during the third quarter of 2010 for a dispute involving a pipeline in South Texas.

Gross operating margin from our NGL fractionation business was $137.9 million for 2010 compared to $136.0 million for 2009, a $1.9 million increase year-to-year. Our NGL fractionation volumes were 485 MBPD during 2010 compared to 461 MBPD during 2009. Gross operating margin from our Mont Belvieu and Promix NGL fractionation facilities increased $15.1 million year-to-year primarily due to higher NGL fractionation volumes and fees. During the fourth quarter of 2010, we added 75 MBPD of NGL fractionation capacity by completing and placing into service a fourth NGL fractionator at our complex in Mont Belvieu, Texas. Gross operating margin from the remainder of our NGL fractionators decreased $13.2 million year-to-year, primarily due to a $12.6 million year-to-year decrease in gross operating margin from our Norco fractionator related to hedging and operating gains recorded during 2009 that did not repeat in 2010.

Onshore Natural Gas Pipelines & Services . Gross operating margin from this business segment was $527.2 million for 2010 compared to $501.5 million for 2009, a $25.7 million year-to-year increase. Our onshore natural gas transportation volumes were 11.48 TBtus/d during 2010 compared to 10.44 TBtus/d during 2009.

Gross operating margin from our onshore natural gas pipelines and related marketing business was $471.7 million for 2010 compared to $448.5 million for 2009, a $23.2 million year-to-year increase. Gross operating margin for 2010 includes $33.0 million from the State Line and Fairplay natural gas gathering systems, which we acquired in May 2010. Gross operating margin from our Texas Intrastate System increased $22.0 million year-to-year primarily due to higher firm capacity reservation fees on the Sherman Extension pipeline. Gross operating margin from our San Juan Gathering System increased $21.1 million year-to-year primarily due to higher average gathering fees and lower operating expenses during 2010 compared to 2009. Our Central Treating Facility in the Rocky Mountains, which commenced operations in March 2009, contributed $11.5 million of the year-to-year increase in segment gross operating margin. Collectively, gross operating margin from our Jonah and Carlsbad gathering systems decreased $16.0 million year-to-year primarily due to lower natural gas gathering volumes. Collectively, gross operating margin from the remainder of our onshore natural gas pipelines and related marketing activities decreased $48.4 million year-to-year primarily due to lower sales margins and higher transportation and storage expenses associated with our natural gas marketing activities.

Natural gas basis differentials in Texas (specifically, the difference in natural gas prices between markets in West Texas and East Texas) were significantly lower during 2010 relative to 2009. The year-to-year decrease in basis differentials resulted in lower sales margins associated with our natural gas marketing activities during 2010 and a decrease in interruptible transportation volumes on our Texas Intrastate System.

Gross operating margin from our natural gas storage business was $55.5 million for 2010 compared to $53.0 million for 2009. The $2.5 million year-to-year increase in gross operating margin is primarily due to higher revenues and lower operating expenses at our Petal natural gas storage facility during 2010 compared to 2009.

Onshore Crude Oil Pipelines & Services . Gross operating margin from this business segment was $113.7 million for 2010 compared to $164.4 million for 2009, a $50.7 million year-to-year decrease. Total onshore crude oil transportation volumes decreased to 670 MBPD during 2010 compared to 680 MBPD during 2009. Gross operating margin from our crude oil marketing and related activities decreased $53.9 million year-to-year primarily due to lower sales margins resulting from a competitive crude oil marketing environment (i.e., lower basis differentials year-to-year) and higher pipeline and truck transportation costs. Basis differentials represent the difference in crude oil prices between two locations or price differences for various qualities of crude oil (e.g., “sweet” crude versus “sour” crude). Gross operating margin from our crude oil terminal operations in Midland, Texas and Cushing, Oklahoma decreased $3.6 million year-to-year primarily due to higher operating expenses. Collectively, gross operations from the remainder of our onshore crude oil businesses increased $6.8 million year-to-year primarily due to higher throughput volumes on our West Texas pipeline system and higher volumes and fees on our Red River pipeline system.

Offshore Pipelines & Services . Gross operating margin from this business segment was $297.8 million for 2010 compared to $180.5 million for 2009, a $117.3 million year-to-year increase.

Table of Contents

include $135.3 million of charges related to our dissociation from TOPS. Gross operating margin from this business segment decreased $5.8 million year-to-year excluding the effects of insurance proceeds and charges related to TOPS.

In August 2008, we, including TEPPCO, together with Oiltanking Holding Americas, Inc. (“Oiltanking”) formed TOPS. In April 2009, we and TEPPCO dissociated from TOPS and recorded a $68.4 million charge to write-off our investment in the joint venture. In September 2009, we entered into a settlement agreement with certain affiliates of Oiltanking that resolved all disputes between the parties related to the business and affairs of the TOPS project. We recognized approximately $66.9 million of expense during the third quarter of 2009 in connection with the payment of this cash settlement.

The following paragraphs provide a discussion of segment results excluding insurance-related gains and the charges associated with TOPS.

In general, natural gas and crude oil drilling activity in the Gulf of Mexico ceased as a result of the federal offshore drilling moratorium, which went into effect in May 2010. This resulted in lower throughput volumes available to certain of our offshore pipeline and platform assets. The moratorium was lifted in October 2010.

Gross operating margin from our offshore crude oil pipeline business was $97.9 million for 2010 compared to $79.3 million for 2009, an $18.6 million year-to-year increase. Equity earnings from Poseidon increased $5.7 million year-to-year primarily due to higher transportation volumes and lower operating expenses. In addition, gross operating margin from our Shenzi crude oil pipeline, which commenced operations in April 2009, increased $4.0 million year-to-year. Collectively, gross operating margin from the remainder of our crude oil pipelines increased $8.9 million year-to-year primarily due to increased transportation volumes. Certain of these pipelines were either in limited service or out-of-service completely during 2009 due to the lingering effects of Hurricanes Gustav and Ike on energy infrastructure in the Gulf of Mexico. Despite the effects of the federal offshore drilling moratorium, our offshore crude oil transportation volumes averaged 320 MBPD during 2010 compared to 308 MBPD during 2009.

Gross operating margin from our offshore natural gas pipeline business was $45.5 million for 2010 compared to $54.2 million for 2009, an $8.7 million year-to-year decrease. Our offshore natural gas transportation volumes were 1,242 BBtus/d during 2010 versus 1,420 BBtus/d during 2009. Gross operating margin from our Independence Trail pipeline decreased $31.2 million year-to-year primarily due to lower transportation volumes. Natural gas transportation volumes on our Independence Trail pipeline decreased to 576 BBtus/d during 2010 from 805 BBtus/d during 2009 as a result of well depletion and lost production (i.e., wells that were shut-in or watered-out) and indirect impacts of the federal offshore drilling moratorium. Collectively, gross operating margin from the remainder of our offshore natural gas pipelines increased $22.5 million year-to-year primarily due to a year-to-year decrease in operating expenses as a result of property damage repair expenses we recorded during 2009 and revenue increases on our High Island Offshore System in 2010.

Gross operating margin from our offshore platform services business was $126.9 million for 2010 compared to $142.6 million for 2009, a $15.7 million year-to-year decrease. Our net platform natural gas processing volumes were 513 MMcf/d during 2010 compared to 700 MMcf/d during 2009. The year-to-year decrease in gross operating margin is primarily due to lower natural gas processing volumes at our Independence Hub platform as a result of well depletion and lost production (i.e., wells that were shut-in or watered-out) and indirect impacts of the federal offshore drilling moratorium.

Petrochemical & Refined Products Services . Gross operating margin from this business segment was $584.5 million for 2010 compared to $364.7 million for 2009, a $219.8 million year-to-year increase.

Gross operating margin from propylene fractionation and related activities was $212.4 million for 2010 compared to $89.6 million for 2009, a $122.8 million year-to-year increase. Propylene fractionation volumes increased to 77 MBPD during 2010 from 68 MBPD during 2009. The year-to-year increase in gross operating margin is primarily due to higher propylene fractionation volumes and sales margins during 2010. Propylene sales margins increased year-to-year as a result of improved consumer demand for propylene derivative products and lower propylene production from third party petrochemical facilities (which impacted supply) during 2010 compared to 2009.

Table of Contents

Gross operating margin from octane enhancement and HPIB production was $47.0 million for 2010 compared to $11.5 million for 2009, a $35.5 million year-to-year increase. Octane enhancement production volumes were 16 MBPD during 2010 compared to 10 MBPD during 2009. The year-to-year increase in gross operating margin is primarily due to higher sales volumes and margins from motor gasoline additives and revenues from by-product sales.

Gross operating margin from butane isomerization was $84.9 million for 2010 compared to $76.2 million for 2009, an $8.7 million year-to-year increase. Butane isomerization volumes decreased to 89 MBPD during 2010 from 97 MBPD during 2009. The year-to-year increase in gross operating margin is primarily due to higher commodity prices, which resulted in increased revenues from by-product sales and more than offset the effect of lower isomerization volumes.

Gross operating margin from refined products pipelines and related activities was $170.8 million for 2010 compared to $124.7 million for 2009, a $46.1 million year-to-year increase. Pipeline transportation volumes for the refined products business were 734 MBPD during 2010 compared to 682 MBPD during 2009. Gross operating margin for 2009 includes a $28.7 million charge recognized by TEPPCO in the third quarter of 2009 in connection with its river terminal business. Collectively, gross operating margin from the remainder of our refined products pipelines and related activities increased $17.4 million year-to-year primarily due to the expansion of our refined products marketing activities and the completion of our 5.3 million barrel refined products terminal in Port Arthur, Texas, which generated $7.4 million of gross operating margin for 2010.

Gross operating margin from marine transportation and other segment services was $69.4 million for 2010 compared to $62.7 million for 2009, a $6.7 million year-to-year increase. An increase in gross operating margin attributable to earnings from acquired and constructed marine vessels was partially offset by higher operating expenses during 2010 as compared to 2009.

Other Investments . Our equity earnings from Energy Transfer Equity were a loss of $2.8 million for 2010 compared to income of $41.1 million for 2009, a $43.9 million year-to-year decrease. Our equity income from this investment was reduced by $36.3 million and $36.6 million of excess cost amortization during 2010 and 2009, respectively. According to financial statements filed with the SEC, Energy Transfer Equity’s net income attributable to partners was $192.8 million and $442.5 million for 2010 and 2009, respectively. Energy Transfer Equity’s net income attributable to partners for 2010 included $66.4 million of charges in connection with the termination of interest rate swaps and a $52.6 million non-cash impairment charge to write-down the carrying value of its investment in Midcontinent Express Pipeline, LLC. In addition, Energy Transfer Equity’s net income for 2010 included losses of $52.4 million associated with the change in fair value of non-hedged interest rate derivatives compared to gains of $33.6 million for 2009.

Liquidity and Capital Resources

At December 31, 2011, we had $3.37 billion of consolidated liquidity, which is defined as unrestricted cash on hand plus borrowing capacity available under our $3.5 Billion Multi-Year Revolving Credit Facility. Our primary cash requirements are for routine operating expenses, debt service, working capital, capital expenditures, business combinations and distributions to partners. We expect to fund our short-term cash requirements for operating expenses and sustaining capital expenditures using operating cash flows and borrowings under our revolving credit facility. Our expenditures for long-term productive assets (e.g., business expansion projects and acquisitions) are expected to be funded through a variety of sources (either separately or in combination) including the use of operating cash flows, borrowings under our revolving credit facility, proceeds from divestitures and the issuance of additional equity and debt securities. We expect to fund cash distributions to partners primarily with operating cash flows. Our debt service requirements are expected to be funded by operating cash flows and/or refinancing arrangements. Based on current market conditions, 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.

Long-Term Debt

In September 2011, EPO entered into a new $3.5 Billion Multi-Year Revolving Credit Facility that matures in September 2016. Initial borrowings under this variable-rate credit facility were used to refinance and terminate

Table of Contents

EPO’s prior $1.75 Billion Multi-Year Revolving Credit Facility. Future borrowings under the new $3.5 billion revolving credit facility may be used for working capital, capital expenditures, acquisitions and general company purposes. EPO’s borrowings under the revolving credit facility are unsecured general obligations that are guaranteed by Enterprise and are non-recourse to Enterprise GP.

As defined by the credit agreement, variable interest rates charged under this facility bear interest at a London Interbank Offer Rate (“LIBOR”) plus an applicable margin. In addition, EPO is required to pay a quarterly facility fee on each lender’s commitment irrespective of commitment usage. This revolving credit facility allows us to request up to two one-year extensions of the maturity date, subject to lender approval. The total amount of the bank commitments may be increased, without the consent of the lenders, by an amount not exceeding $500 million by adding one or more lenders to the facility and/or requesting that the commitments of existing lenders be increased.

We had approximately $14.48 billion of principal amounts outstanding under consolidated debt agreements at December 31, 2011. In January 2011, EPO issued $750.0 million in principal amount of 5-year unsecured notes (“Senior Notes AA”) and $750.0 million in principal amount of 30-year unsecured notes (“Senior Notes BB”). Senior Notes AA were issued at 99.901% of their principal amount, have a fixed interest rate of 3.20%, and mature in February 2016. Senior Notes BB were issued at 99.317% of their principal amount, have a fixed interest rate of 5.95%, and mature in February 2041. Net proceeds from the issuance of Senior Notes AA and BB were used to repay $450.0 million in aggregate principal amount of Senior Notes B that matured in February 2011, to temporarily reduce borrowings outstanding under EPO’s $1.75 Billion Multi-Year Revolving Credit Facility and for general company purposes.

In August 2011, EPO issued $650.0 million in principal amount of 10-year unsecured notes (“Senior Notes CC”) and $600.0 million in principal amount of 30-year unsecured notes (“Senior Notes DD”). Senior Notes CC were issued at 99.790% of their principal amount, have a fixed interest rate of 4.05%, and mature in February 2022. Senior Notes DD were issued at 99.887% of their principal amount, have a fixed interest rate of 5.70%, and mature in February 2042. Net proceeds from the issuance of Senior Notes CC and DD were used to temporarily reduce borrowings outstanding under EPO’s $1.75 Billion Multi-Year Revolving Credit Facility and for general company purposes.

In February 2012, EPO issued $750.0 million in principal amount of 30-year unsecured Senior Notes EE. These notes were issued at 99.542% of their principal amount, have a fixed-rate of interest of 4.85% and mature on August 15, 2042. Net proceeds from the issuance of Senior Notes EE were used to temporarily reduce borrowings outstanding under EPO’s $3.5 Billion Multi-Year Revolving Credit Facility (which was used to repay at maturity its $490.5 million principal amount of Senior Notes S due February 2012 and $9.5 million principal amount of TEPPCO Senior Notes due February 2012 prior to the delivery of Senior Notes EE) and for general company purposes.

Our $3.5 Billion Multi-Year Revolving Credit Facility and each of our indentures for our public debt contain conventional financial covenants and other restrictions. For example, EPO’s ability to make distributions to Enterprise Products Partners L.P., and our ability to make distributions to our partners, would be restricted if an event of default exists or if such distributions would cause an event of default or otherwise violate a covenant under the revolving credit facility. Our revolving credit facility also restricts our ability to incur additional debt above certain levels. Our public debt indentures currently do not limit the amount of future indebtedness that we can create, incur, assume or guarantee.

We were in compliance with the financial covenants of our consolidated debt agreements at December 31, 2011. For additional information regarding our consolidated debt obligations, see Note 12 of the Notes to Consolidated Financial Statements included under Item 8 of this annual report.

Registration Statements

We may issue additional equity or debt securities to assist us in meeting our future liquidity and capital spending requirements. In July 2010, Enterprise, including EPO, filed a universal shelf registration statement (the “2010 Shelf”) with the SEC. The 2010 Shelf allows Enterprise and EPO (on a standalone basis) to issue an

Table of Contents

unlimited amount of equity and debt securities, respectively. EPO utilized the 2010 Shelf to issue its Senior Notes AA and BB in January 2011, Senior Notes CC and DD in August 2011 and Senior Notes EE in February 2012.

In December 2011, Enterprise utilized the 2010 Shelf to issue 10,350,000 of its common units, including the exercise of an over-allotment option for 1,350,000 common units, at $44.68 per unit in an underwritten public offering. Total net cash proceeds from the December 2011 equity offering, including the exercise of the over-allotment option, were approximately $448.5 million after deducting underwriting discounts, commissions and offering expenses.

Enterprise also has a registration statement on file with the SEC in connection with its distribution reinvestment plan (“DRIP”). Enterprise issued 2,241,589 common units in total under its DRIP plan during 2011, which generated net cash proceeds of $90.4 million. After taking into account the number of common units issued under this registration statement through December 31, 2011, Enterprise may issue an additional 26,173,283 common units under its DRIP.

In May 2011, Enterprise’s original employee unit purchase plan (“EUPP”) reached the maximum 1,200,000 common units permitted under the plan and was terminated. In September 2011, in connection with the Duncan Merger, the Duncan Energy Partners EUPP was assumed by Enterprise and converted into a new Enterprise EUPP. Enterprise filed a registration statement with the SEC authorizing the issuance of 440,879 common units under the assumed plan. Enterprise issued 96,315 common units in total under its EUPP plans during 2011, which generated net cash proceeds of $4.0 million.

The net cash proceeds received in 2011 from Enterprise’s DRIP and EUPP were used to temporarily reduce borrowings outstanding under EPO’s revolving credit facilities and for general company purposes.

Credit Ratings

As of February 29, 2012, the investment-grade credit ratings of EPO’s senior unsecured debt securities were: BBB from Standard and Poor’s; Baa2 from Moody’s; and BBB from Fitch Ratings. In January 2012, Standard & Poor’s upgraded its corporate credit rating of EPO from BBB- to BBB, while maintaining its outlook for EPO’s business as “positive.” Moody’s did likewise, upgrading its credit rating of EPO from Baa3 to Baa2 and reaffirming that its outlook for EPO’s business remained “positive.” In February 2012, Fitch Ratings upgraded its corporate credit rating of EPO to BBB while maintaining its outlook for EPO’s business as “stable.” 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.

A potential downgrade of EPO’s credit ratings could result in us posting financial collateral in connection with our guaranty of Centennial’s debt, which was $51.0 million at December 31, 2011. Furthermore, we may enter into contracts in connection with our commodity and interest rate hedging activities that may require the posting of financial collateral if EPO’s credit ratings were downgraded below investment grade.

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 Statements of Consolidated Cash Flows included under Item 8 of this annual report.

	For Year Ended December 31,
	2011			2010		2009
Net cash flows provided by operating activities	$	3,330.5		$	2,300.0	$	2,410.3
Cash used in investing activities		2,777.6			3,251.6		1,547.7

Table of Contents

Net cash flows provided by operating activities are largely dependent on earnings from our consolidated business activities. As a result, these cash flows are exposed to certain risks. We operate predominantly in the midstream energy industry. We provide products and services to producers and consumers of natural gas, NGLs, crude oil, refined products and certain petrochemicals. The products that we process, sell, transport or store are principally used as fuel for residential, agricultural and commercial heating; as feedstocks in petrochemical manufacturing; and in the production of motor gasoline. Reduced demand for our services or products by industrial customers, whether because of a decline in general economic conditions, reduced demand for the end products made with our products, or increased competition from other service providers or producers due to pricing differences or other reasons, could have a negative impact on our earnings and operating cash flows. For a more complete discussion of these and other risk factors pertinent to our business, see Item 1A of this annual report.

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

Comparison of 2011 with 2010

Operating Activities . The $1.03 billion increase in net cash flows provided by operating activities was primarily due to increased profitability (e.g., our gross operating margin increased $618.7 million year-to-year) and the timing of related cash receipts and disbursements.

Investing Activities . The $474.0 million decrease in cash used for investing activities was primarily due to the following:

§	Cash used for business combinations decreased $1.31 billion year-to-year, primarily due to the acquisition of the State Line and Fairplay natural gas gathering systems for approximately $1.2 billion in May 2010.

§	Proceeds from asset sales and related transactions increased $927.9 million year-to-year primarily due to the sale of 9,672,576 Energy Transfer Equity common units for $375.2 million and the sale of certain natural gas storage facilities for $547.8 million during 2011.

§	Restricted cash related to our hedging activities decreased $60.2 million (a cash inflow) during 2011 due to changes in the margin requirements of our commodity hedging positions. For 2010, restricted cash related to our hedging activities increased $35.0 million (a cash outflow).

Capital spending for property, plant and equipment, net of contributions in aid of construction costs, increased $1.84 billion year-to-year primarily due to our Eagle Ford Shale and Haynesville Shale growth capital projects. For additional information regarding our capital spending program, see “Liquidity and Capital Resources – Capital Spending” included within this Item 7.

Financing Activities . As discussed under “Basis of Financial Statement Presentation” within this Item 7, the financial statements of Enterprise prior to the Holdings Merger were those of Holdings. As a result, cash distributions paid to partners during 2010 represent payments to the former unitholders of Holdings whereas cash distributions paid to partners during 2011 represent payments to the unitholders of Enterprise. Also, cash distributions paid to noncontrolling interests during 2010 include cash payments to the unitholders of Enterprise (other than Holdings). Cash contributions from noncontrolling interests during 2010 primarily represent proceeds from Enterprise’s equity offerings (other than purchases by Holdings).

Cash used in financing activities was $598.6 million during 2011 compared to cash provided by financing activities of $961.1 million during 2010. The $1.56 billion decrease in cash flows from financing activities was primarily due to the following:

On a combined basis, cash contributions from noncontrolling interests and net cash proceeds from the issuance of common units decreased $1.08 billion year-to-year. Substantially all of the cash contributions from noncontrolling interests during 2010 relate to net cash proceeds generated from the issuance of common units by Enterprise prior to the completion of the Holdings Merger. In total, Enterprise issued

100

Table of Contents

12,687,904 common units and 46,328,053 common units during 2011 and 2010, respectively, in connection with underwritten offerings and its DRIP and EUPP.

Cash distributions to partners and noncontrolling interests were a combined $2.04 billion during 2011 compared to $1.79 billion during 2010. The increase in cash distributions is primarily due to increases in the number of Enterprise’s distribution-bearing common units outstanding (including common units issued in connection with the Holdings Merger and Duncan Merger) and in its quarterly distribution rates.

Net borrowings under our consolidated debt agreements decreased $191.7 million year-to-year. EPO issued $2.75 billion of new senior notes and repaid $450.0 million in senior notes during 2011 compared to the issuance of $2.0 billion in senior notes and repayment of $500.0 million in senior notes and $54.0 million of other long-term debt during 2010. In addition, net repayments under consolidated revolving credit facilities and term loans increased approximately $988.3 million year-to-year. For additional information regarding our consolidated debt obligations, see Note 12 of the Notes to Consolidated Financial Statements included under Item 8 of this annual report.

Comparison of 2010 with 2009

Operating Activities . The $110.3 million decrease in net cash flows provided by operating activities was primarily due to the following:

Net cash flows from consolidated operations (excluding cash payments for interest, distributions received from unconsolidated affiliates and cash payments for income taxes) decreased $69.5 million year-to-year. The decrease in cash flows from operating activities is generally due to the timing of cash receipts and disbursements in our operating accounts, partially offset by increased profitability (e.g., our gross operating margin increased $372.1 million year-to-year).

§	Cash payments for interest increased approximately $77.3 million year-to-year primarily due to an increase in fixed-rate debt obligations with higher interest rates. Our average consolidated debt principal outstanding was $13.23 billion during 2010 compared to $13.0 billion during 2009.

§	Distributions received from unconsolidated affiliates increased $22.6 million year-to-year primarily due to higher distributions received from Poseidon and Promix. In February 2010, we also began receiving distributions from Skelly-Belvieu Pipeline Company, L.L.C.

§	Cash payments for income taxes decreased $13.9 million year-to-year primarily due to higher payments made in 2009 attributable to the Texas Margin Tax and a taxable gain arising from the sale of certain Dixie assets.

Investing Activities . The $1.7 billion increase in cash used for investing activities was primarily due to the following:

Cash used for business combinations increased $1.21 billion year-to-year, primarily due to the May 2010 acquisition of the State Line and Fairplay natural gas gathering systems for approximately $1.2 billion. For additional information regarding this transaction, see Note 10 of the Notes to Consolidated Financial Statements included under Item 8 of this annual report.

§	Capital spending for property, plant and equipment, net of contributions in aid of construction costs, increased $435.6 million year-to-year primarily due to our Eagle Ford Shale and Haynesville Shale growth capital projects.

§	Restricted cash related to our hedging activities increased $35.0 million (a cash outflow) during 2010 due to changes in the margin requirements of our commodity hedging positions. For 2009, restricted cash related to our hedging activities decreased $140.2 million (a cash inflow).

101

Table of Contents

Proceeds from asset sales and related transactions increased $102.3 million year-to-year primarily due to insurance proceeds received during 2010 related to the disposal of certain offshore pipeline and platform assets and the sale of our membership interest in the general partner of Energy Transfer Equity.

Financing Activities . Cash provided by financing activities was $961.1 million during 2010 compared to cash used in financing activities of $863.9 million during 2009. The $1.83 billion year-to-year change in financing activities was primarily due to the following:

Net borrowings under our consolidated debt agreements increased $1.41 billion year-to-year. EPO issued $2.0 billion in senior notes during 2010 compared to $1.6 billion in senior notes and during 2009. In addition, net repayments under consolidated revolving credit facilities decreased approximately $1.07 billion year-to-year.

Cash contributions from noncontrolling interests increased $89.5 million year-to-year primarily due to an increase in the offering prices of Enterprise’s common units in connection with its underwritten equity offerings in 2010 compared to those in 2009. In addition, Duncan Energy Partners issued common units in 2009, which generated $137.4 million in proceeds. Net cash proceeds from the issuance of Enterprise common units in December 2010, following the Holdings Merger, were $528.5 million.

§	Cash distributions paid to partners (i.e., the unitholders of Holdings prior to the Holdings Merger) increased $41.0 million year-to-year due to increases in Holdings’ quarterly distribution rates and in the number of its distribution-bearing units outstanding.

Cash distributions paid to noncontrolling interests increased $156.3 million year-to-year primarily due to increases in the number of Enterprise’s distribution-bearing common units outstanding and in its quarterly distribution rates, partially offset by the cessation of cash distributions to the former owners of TEPPCO in connection with the TEPPCO Merger.

Capital Spending

An integral 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 system 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, Midcontinent, Northeast and U.S. Gulf Coast regions, including the Barnett, Eagle Ford, Haynesville, Marcellus and Utica Shale plays and deepwater Gulf of Mexico producing regions. See “Significant Recent Developments” within this Item 7 for information regarding our current and proposed major capital projects, including the development of our ATEX Express long-haul ethane pipeline, SEKCO crude oil pipeline and multiple projects in the Eagle Ford Shale.

Although our current focus is on expansion through growth capital projects, management continues to analyze potential business combinations, joint ventures and similar transactions with businesses that operate in complementary markets or geographic regions. In past years, major oil and gas companies have sold non-strategic assets in the midstream energy sector in which we operate. We believe this trend will continue and expect independent oil and natural gas companies to consider similar divestitures.

Table of Contents

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

	For Year Ended December 31,
	2011		2010		2009
Capital spending for property, plant and equipment, net: (1)
Growth capital projects (2)	$	3,552.3	$	1,766.2	$	1,373.9
Sustaining capital projects (3)		290.3		235.9		192.6
Capital spending for business combinations		--		1,313.9		107.3
Investments in unconsolidated affiliates		30.0		8.0		19.6
Other investing activities		22.4		--		1.4
Total capital spending	$	3,895.0	$	3,324.0	$	1,694.8

(1) 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 and production well tie-ins. Contributions in aid of construction costs were $24.9 million, $38.7 million and $17.8 million for the years ended December 31, 2011, 2010 and 2009, respectively. Growth and sustaining capital amounts presented in the table are presented net of related contributions in aid of construction costs. (2) Growth capital projects either result in additional revenue streams from existing assets or expand our asset base through construction of new facilities that will generate additional revenue streams. (3) Sustaining capital expenditures are capital expenditures (as defined by GAAP) resulting from improvements to and major renewals of existing assets. Such expenditures serve to maintain existing operations but do not generate additional revenues.

Based on information currently available, we estimate our consolidated capital spending for 2012 will approximate $3.8 billion, which includes estimated expenditures of $3.5 billion for growth capital projects and $315 million for sustaining capital expenditures. Our forecast of consolidated capital expenditures for 2012 is based on our announced strategic operating and growth plans, which are dependent upon our ability to generate the required funds from either operating cash flows or other means, including borrowings under debt agreements, issuance of additional debt and equity securities, and potential divestitures. We may revise our forecast of capital spending due to factors beyond our control, such as weather related issues, changes in supplier prices or adverse economic conditions. Furthermore, our forecast of capital spending may change as a result of decisions made by management at a later date, which may include the addition of costs associated with unforeseen acquisition opportunities.

Our success in raising capital, including the formation of joint ventures to share costs and risks, continues to be a principal 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 currently intend to make the forecast capital expenditures noted above, we may adjust the timing and amounts of projected expenditures in response to changes in capital markets.

At December 31, 2011, we had approximately $1.31 billion in purchase commitments outstanding that relate to our capital spending for property, plant and equipment. These commitments primarily relate to construction projects in Texas, including those in the Eagle Ford Shale and at our Mont Belvieu facility.

Pipeline Integrity Costs

Our pipelines are subject to safety programs administered by the U.S. Department of Transportation (“DOT”). This federal agency has issued safety regulations containing requirements for the development of integrity management programs for hazardous liquid pipelines (e.g., NGL, crude oil, refined products and petrochemical pipelines) and natural gas pipelines. In general, these regulations require companies to assess the condition of their pipelines in certain high consequence areas (as defined by the regulation) and to perform any necessary repairs. The following table summarizes our pipeline integrity costs, including those attributable to DOT regulations, for the periods presented (dollars in millions):

	For Year Ended December 31,
	2011		2010		2009
Expensed	$	64.7	$	39.4	$	44.9
Capitalized		52.6		40.4		37.7
Total	$	117.3	$	79.8	$	82.6

We expect the cost of our pipeline integrity program, irrespective of whether such costs are capitalized or expensed, to approximate $101.0 million in 2012.

Critical Accounting Policies and Estimates

In our financial reporting processes, we employ methods, estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of our financial statements. These methods, estimates and assumptions also affect the reported amounts of revenues and expenses for each reporting period. Investors should be aware that actual results could differ from these estimates if the underlying assumptions prove to be incorrect. The following describes the estimation risk currently underlying our most significant financial statement items:

Depreciation Methods and Estimated Useful Lives of Property, Plant and Equipment

In general, depreciation is the systematic and rational allocation of an asset’s cost, less its residual value (if any), to the periods it benefits. The majority of our property, plant and equipment is depreciated using the straight-line method, which results in depreciation expense being incurred evenly over the life of an asset. Our estimate of depreciation expense incorporates management assumptions regarding the useful economic lives and residual values of our assets. At the time we place our assets in service, we believe such assumptions are reasonable; however, circumstances may develop that would cause us to change these assumptions, which would change our depreciation amounts prospectively. Examples of such circumstances include (i) changes in laws and regulations that limit the estimated economic life of an asset, (ii) changes in technology that render an asset obsolete, (iii) changes in expected salvage values, or (iv) significant changes in the forecast life of proved reserves of applicable resource basins, if any.

104

Table of Contents

At December 31, 2011 and 2010, the net carrying value of our property, plant and equipment was $22.19 billion and $19.33 billion, respectively. We recorded $776.6 million, $745.7 million and $678.1 million in depreciation expense for the years ended December 31, 2011, 2010 and 2009, respectively.

Measuring Recoverability of Long-Lived Assets and Equity Method Investments

Long-lived assets, which include property, plant and equipment and intangible assets with finite useful lives, are reviewed for impairment whenever events or changes in circumstances indicate that their carrying amount may not be recoverable. Examples of such events or changes might be production declines that are not replaced by new discoveries or long-term decreases in the demand or price of natural gas, NGLs, crude oil or refined products. The carrying value of a long-lived asset is not recoverable if it exceeds the sum of undiscounted estimated cash flows expected to result from the use and eventual disposition of the asset. Estimates of undiscounted cash flows are based on a number of assumptions including anticipated operating margins and volumes; estimated useful life of the asset or asset group; and estimated salvage values. If the carrying value of a long-lived asset is not recoverable, an impairment charge would be recorded for the excess of a long-lived asset’s carrying value over its estimated fair value, which is derived from an analysis of the asset’s estimated future cash flows, the market value of similar assets and replacement cost of the asset less any applicable depreciation or amortization. In addition, fair value estimates also include usage of probabilities for a range of possible outcomes.

An equity method investment is evaluated for impairment whenever events or changes in circumstances indicate that there is a possible permanent loss in value of the investment (i.e., other than a temporary decline). Examples of such events include sustained operating losses of the investee or long-term negative changes in the investee’s industry. The carrying value of an equity method investment is not recoverable if it exceeds the sum of discounted estimated cash flows expected to be derived from the investment. Estimates of discounted cash flows are based on a number of assumptions including discount rates; probabilities assigned to different cash flow scenarios; anticipated margins and volumes and estimated useful life of the investment’s underlying assets.

A significant change in the assumptions we use to measure recoverability of long-lived assets and equity method investments could result in our recording a non-cash impairment charge. Any such write-down of the value of such assets would increase operating costs and expenses at that time. During 2011, 2010 and 2009, we recognized non-cash asset impairment charges related to property, plant and equipment of $16.7 million, $8.0 million and $29.3 million, respectively, which are a component of operating costs and expenses. For additional information regarding these impairment charges, see Note 6 of the Notes to Consolidated Financial Statements included under Item 8 of this annual report. We did not record any non-cash impairment charges related to our equity method investments in 2011, 2010 or 2009.

Amortization Methods and Estimated Useful Lives of Qualifying Intangible Assets

The specific, identifiable intangible assets of a business depend largely upon the nature of its operations. Potential identifiable intangible assets include items such as intellectual property, customer contracts and relationships, and non-compete agreements. The method used to value each intangible asset will vary depending upon a number of factors, including the nature of the asset and the economic returns it is generating or is expected to generate.

Customer relationship intangible assets represent the estimated economic value we assigned to information about customers and the ability to have regular contact with them as a result of business combinations and assets purchases. These relationships may arise from formal contractual arrangements or through routine contact by sales or service representatives. The value we assign to customer relationships is amortized to earnings using methods that closely resemble the pattern in which the economic benefits of the associated oil and natural gas resource basins from which the customers produce are estimated to be depleted. Our estimate of the useful life of each resource basin is predicated on a number of factors, including reserve estimates and the economic viability of production and exploration activities.

Our contract-based intangible assets represent rights we own arising from discrete contractual agreements, such as the long-term rights we possess under the Shell natural gas processing agreement and the Jonah natural gas transportation contracts. A contract-based intangible asset with a finite life is amortized over its estimated useful

105

Table of Contents

life (or term), which is the period over which the asset is expected to contribute directly or indirectly to our cash flows. Our estimates of useful life are based on a number of factors, including (i) the expected useful life of the related tangible assets (e.g., a fractionation facility, pipeline or other asset), (ii) any legal or regulatory developments that would impact such contractual rights, and (iii) any contractual provisions that enable us to renew or extend such agreements.

If our assumptions regarding the estimated useful life of an intangible asset were to change, then the amortization period for such asset would be adjusted accordingly. Changes in the estimated useful life of an intangible asset would impact operating costs and expenses prospectively from the date of change. If we determine that an intangible asset’s unamortized cost is not recoverable due to impairment, we would be required to reduce the asset’s carrying value to its estimated fair value. Any such write-down of the value of an intangible asset would increase operating costs and expenses at that time.

At December 31, 2011 and 2010, the carrying value of our intangible asset portfolio was $1.66 billion and $1.84 billion, respectively. We recorded $147.0 million, $137.6 million and $119.9 million in amortization expense associated with our intangible assets for the years ended December 31, 2011, 2010 and 2009, respectively.

For additional information regarding our intangible assets, see Note 11 of the Notes to Consolidated Financial Statements included under Item 8 of this annual report.

Methods We Employ to Measure the Fair Value of Goodwill

Goodwill represents the excess of the purchase price of an acquired business over the amounts assigned to assets acquired and liabilities assumed in the transaction. Goodwill is not amortized; however, it is subject to annual impairment testing at the end of each fiscal year, and more frequently, if circumstances indicate it is probable that the fair value of goodwill is below its carrying amount. Goodwill impairment testing involves determining the fair value of the associated reporting unit. These fair value amounts are based on assumptions regarding the future economic prospects of the businesses that make up the reporting unit. Such assumptions include (i) discrete financial forecasts for the businesses contained within the reporting unit, which rely on management’s estimates of operating margins, throughput volumes and similar factors; (ii) long-term growth rates for cash flows beyond the discrete forecast period; and (iii) appropriate discount rates.

If the fair value of a reporting unit (including its inherent goodwill) is less than its carrying value, a charge to operating costs and expenses is required to reduce the carrying value of the goodwill to its implied fair value. Based on our most recent goodwill impairment test, the estimated fair value of each of our reporting units was substantially in excess of its carrying value (i.e., by at least 10%).

At December 31, 2011 and 2010, the carrying value of our goodwill was $2.09 billion and $2.11 billion, respectively. We did not record any goodwill impairment charges in 2011 or 2010; however, we did recognize a $1.3 million goodwill impairment charge in 2009. For additional information regarding our goodwill, see Note 11 of the Notes to Consolidated Financial Statements included under Item 8 of this annual report.

Revenue Recognition Policies and Use of Estimates for Revenues and Expenses

In general, we recognize revenue from customers when all of the following criteria are met: (i) persuasive evidence of an exchange arrangement exists; (ii) delivery has occurred or services have been rendered; (iii) the buyer’s price is fixed or determinable; and (iv) collectibility is reasonably assured. We record revenue when sales contracts are settled (i.e., either physical delivery of product has taken place or the services designated in the contract have been performed). For additional information regarding our revenue recognition policies, see Note 4 of the Notes to Consolidated Financial Statements included under Item 8 of this annual report. We record any necessary allowance for doubtful accounts as required by our established policy.

Our use of estimates for certain revenues and expenses has increased as a result of SEC regulations that require us to submit financial information on accelerated time frames. Such estimates are necessary due to the time required to compile actual billing information and receive third party data needed to record transactions for financial reporting purposes. One example of our use of estimates is the accrual of an estimate of processing plant revenue

106

Table of Contents

and the cost of natural gas for a given month (prior to receiving actual customer and vendor-related plant operating information for a specific period). These estimates reverse in the following month and are offset by the corresponding actual customer billing and vendor-invoiced amounts. Accordingly, we include one month of certain estimated data in our results of operations. Such estimates are generally based on actual volume and price data through the first part of the month and estimated for the remainder of the month.

Changes in facts and circumstances may result in revised estimates and could affect our reported financial statements and accompanying disclosures. If the assumptions underlying our revenue and expense estimates prove to be substantially incorrect, it could result in material adjustments in results of operations between periods. We review our estimates based on currently available information.

(1) Represents contractually scheduled future maturities of our consolidated debt principal obligations after taking into consideration the long-term refinancing of Senior Notes S and the TEPPCO Senior Notes due February 2012 using proceeds from the issuance of Senior Notes EE on February 15, 2012. For information regarding our consolidated debt obligations, see Notes 12 and 23 of the Notes to Consolidated Financial Statements included under Item 8 of this annual report. (2) Estimated cash payments for interest are based on the principal amount of our consolidated debt obligations outstanding at December 31, 2011, the scheduled maturities of such balances (after taking into account the issuance of Senior Notes EE and related refinancing activities as noted above), and the applicable fixed or variable interest rates paid during 2011. With respect to our variable-rate debt obligations, we applied the weighted-average interest rate paid during 2011 to determine the estimated cash payments. See Note 12 of the Notes to Consolidated Financial Statements included under Item 8 of this annual report for the weighted-average variable interest rates charged in 2011 under our credit agreements. In addition, our estimate of cash payments for interest gives effect to interest rate swap agreements that were in place at December 31, 2011. See Note 6 of the Notes to Consolidated Financial Statements included under Item 8 of this annual report for information regarding these derivative instruments. Our estimated cash payments for interest are significantly influenced by the long-term maturities of our junior subordinated notes (due August 2066 through January 2068). Our estimated cash payments for interest with respect to each junior subordinated note are based on the current fixed interest rate for each note applied to the entire remaining term through the respective maturity date. (3) Primarily represents leases of underground salt dome caverns for the storage of natural gas and NGLs, office space with affiliates of EPCO and land held pursuant to right-of-way agreements. (4) Represents enforceable and legally binding agreements to purchase goods or services as of December 31, 2011. The estimated payment obligations are based on contractual prices in effect at December 31, 2011 applied to all future volume commitments. Actual future payment obligations may vary depending on prices at the time of delivery. (5) Primarily represents our unconditional payment obligations under firm pipeline transportation contracts. (6) Represents unconditional payment obligations for services to be rendered or products to be delivered in connection with our capital spending program, including our share of the capital spending commitments of our unconsolidated affiliates. (7) As reflected on our consolidated balance sheet at December 31, 2011, other long-term liabilities primarily represent the noncurrent portion of asset retirement obligations, deferred revenues and accrued obligations for pipeline transportation deficiency fees and interest rate derivative instruments.

For additional information regarding our significant contractual obligations, see Note 18 of the Notes to Consolidated Financial Statements included under Item 8 of this annual report.

Non-GAAP Reconciliations

The following table presents a reconciliation of total segment gross operating margin to operating income and further to income before provision for income taxes for the periods indicated (dollars in millions):

	For Year Ended December 31,
	2011			2010			2009
Total segment gross operating margin	$	3,871.7		$	3,253.0		$	2,880.9
Adjustments to reconcile total segment gross operating margin to operating income:
Depreciation, amortization and accretion in operating costs and expenses		(958.7	)		(936.3	)		(809.3	)
Non-cash asset impairment charges		(27.8	)		(8.4	)		(33.5	)
Operating lease expenses paid by EPCO		(0.3	)		(0.7	)		(0.7	)
Gains from asset sales and related transactions in operating costs and expenses		156.0			44.4			--
General and administrative costs		(181.8	)		(204.8	)		(182.8	)
Operating income		2,859.1			2,147.2			1,854.6
Other expense, net		(743.6	)		(737.4	)		(689.0	)
Income before provision for income taxes	$	2,115.5		$	1,409.8		$	1,165.6

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 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. Our non-GAAP financial measure of total segment gross operating margin should not be considered an alternative to GAAP operating income.

We define total segment gross operating margin as operating income before: (i) depreciation, amortization and accretion expenses; (ii) non-cash asset impairment charges; (iii) operating lease expenses for which we did not have the payment obligation; (iv) gains and losses from asset sales and related transactions; and (v) general and administrative costs. 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 the preparation of our Consolidated Financial Statements. Gross operating margin is exclusive of other income and expense transactions, provision for 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.

Recent Accounting Developments

Accounting standard setting organizations have been very active in recent years. Recently, they issued new and revised accounting guidance on a number of topics, including fair value measurements, presentation of comprehensive income, testing goodwill for impairment and balance sheet offsetting. We do not believe that adoption of this new guidance will have a material impact on our future Consolidated Financial Statements. For information regarding these recent accounting developments, see Note 3 of the Notes to Consolidated Financial Statements included under Item 8 of this annual report.

Income Tax Matter

Provision for income taxes primarily relates to our state tax obligations under the Revised Texas Franchise Tax and the federal and state tax obligations of our consolidated subsidiaries taxed as corporations. In January 2012, we submitted applications to the Internal Revenue Service for the conversion of certain of our entities taxed as corporations into pass-through entities. If these conversions are approved, we expect to recognize an income tax benefit during the first quarter of 2012 of approximately $46.5 million, which is attributable to the difference between the deferred taxes accrued by these entities as of the date of conversion and any current income tax due in connection with the conversion.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk.

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 certain anticipated future transactions, we use derivative instruments. Derivatives are financial instruments whose fair values are determined by changes in specified benchmarks such as interest rates or commodity prices. Fair value is defined as the price that would be received to sell an asset or be paid to transfer a liability in an orderly transaction between market participants at a specified measurement date. Derivative instruments typically include futures, forward contracts, swaps, options and other instruments with similar characteristics. Substantially all of our derivatives are used for non-trading activities.

We assess the risk of each of our derivative instrument portfolios using a sensitivity analysis model. The sensitivity analysis applied to each portfolio measures the potential income or loss (i.e., the change in fair value of the derivative instrument portfolio) based upon a hypothetical 10% movement in the underlying interest rates or quoted market prices (as applicable) at the dates indicated. In addition to these variables, the fair value of each portfolio is influenced by fluctuations in the notional amounts of the instruments and the discount rates used to determine the present values.

The calculated results of the sensitivity analysis model do 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: (i) the derivative instrument functions effectively as a hedge of the underlying risk; (ii) the derivative instrument is not closed out in advance of its expected term; and (iii) the hedged forecasted transaction occurs within the expected time period. When considering that the majority of our derivative portfolios are designated as hedges, the sensitivities presented in the quantitative disclosures would most often be expected to have corresponding offsets.

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

Interest Rate Derivative Instruments

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 is a component in controlling our overall cost of capital associated with such borrowings. 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. Forward starting swaps perform a similar function except that they are associated with interest rates underlying anticipated future issuances of debt. The composition of our derivative instrument portfolios may change from period-to-period depending on our hedging requirements.

The following table summarizes our portfolio of interest rate swaps at December 31, 2011 (dollars in millions):

Hedged Transaction	Number and Type of Derivative(s) Outstanding	Notional Amount	Period of Hedge	Rate Swap	Accounting Treatment
Senior Notes C	1 fixed-to-floating swap	$100.0	1/04 to 2/13	6.4% to 2.3%	Fair value hedge
Senior Notes G	3 fixed-to-floating swaps	$300.0	10/04 to 10/14	5.6% to 1.5%	Fair value hedge
Senior Notes P	7 fixed-to-floating swaps	$400.0	6/09 to 8/12	4.6% to 2.7%	Fair value hedge
Senior Notes AA	10 fixed-to-floating swaps	$750.0	1/11 to 2/16	3.2% to 1.3%	Fair value hedge
Undesignated swaps	6 floating-to-fixed swaps	$600.0	5/10 to 7/14	0.4% to 2.0%	Mark-to-market

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

		Interest Rate Swap Portfolio Aggregate Fair Value at (1)
	Resulting	December 31,		December 31,		January 31,
Scenario	Classification	2010		2011		2012
FV assuming no change in underlying interest rates	Asset	$	35.3	$	67.2	$	76.8
FV assuming 10% increase in underlying interest rates	Asset		36.1		64.4		74.8
FV assuming 10% decrease in underlying interest rates	Asset		34.6		70.0		78.8
(1) The portfolio’s aggregate fair value at a given date is based on a variety of factors, including the number and types of derivatives outstanding at that date, the notional value of the swaps and associated interest rates.

In February 2012, we settled eleven fixed-to-floating interest rate swaps having an aggregate notional amount of $800.0 million, resulting in gains totaling $41.7 million. These gains will be amortized to earnings (as a decrease in interest expense) using the effective interest method over the forecasted hedged period.

The following table summarizes our portfolio of forward starting swaps at December 31, 2011 (dollars in millions):

Hedged Transaction	Number and Type of Derivatives Employed	Notional Amount	Expected Termination Date	Average Rate Locked	Accounting Treatment
Future debt offering	10 forward starting swaps (1)	$500.0	2/12	4.5%	Cash flow hedge
Future debt offering	7 forward starting swaps	$350.0	8/12	3.7%	Cash flow hedge
Future debt offering	16 forward starting swaps	$1,000.0	3/13	3.7%	Cash flow hedge
(1) These swaps were settled in February 2012 in connection with the issuance of Senior Notes EE (see below).

FV assuming 10% decrease in underlying interest rates	Liability		(44.3	)		(330.6	)		(354.4	)
(1) The portfolio’s aggregate fair value at a given date is based on a variety of factors, including the number and types of derivatives outstanding at that date, the notional value of the swaps and associated interest rates.

Due to a decrease in forward London Interbank Offered Rates (“LIBOR”) in 2011, the fair value of our forward starting swap portfolio was a liability of $290.7 million at December 31, 2011 and $316.6 million at January 31, 2012. In connection with the issuance of Senior Notes EE in February 2012, we settled ten forward starting swaps having an aggregate notional value of $500.0 million, resulting in losses totaling $115.3 million. These losses will be reflected in other comprehensive income for the first quarter of 2012 and amortized to earnings (as an increase in interest expense) using the effective interest method over the forecasted hedge period of ten years. Any gain or loss ultimately recognized upon settlement of the remaining forward starting swaps would be amortized into earnings as a reduction or increase, respectively, in interest expense over the forecasted hedge period.

Commodity Derivative Instruments

The prices of natural gas, NGLs, crude oil, refined products and certain petrochemical 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 agreements, futures contracts, fixed-for-float swaps, basis swaps and options contracts.

Our predominant hedging strategies are: (i) hedging natural gas processing margins; (ii) hedging anticipated future contracted sales of NGLs, refined products and crude oil associated with volumes held in inventory and (iii) hedging the fair value of natural gas in inventory. The following information summarizes these hedging strategies:

The objective of our natural gas processing strategy is to hedge an amount of gross margin associated with our natural gas processing activities. We achieve this objective by using physical and financial instruments to lock in the purchase prices of natural gas consumed as PTR and the sales prices of the related NGL products. This program consists of (i) the forward sale of a portion of our expected equity NGL production at fixed prices through June 2012, which is achieved through the use of forward physical sales contracts and commodity derivative instruments and (ii) the purchase of commodity derivative instruments having a notional amount based on the volume of natural gas expected to be consumed as PTR in the production of such equity NGL production.

At December 31, 2011, this program had hedged future remaining estimated gross margins (before plant operating expenses) of $108.6 million on 4.2 MMBbls of forecasted NGL forward sales transactions and equivalent PTR volumes extending through June 2012. At January 31, 2012, this program had hedged future estimated gross margins (before plant operating expenses) of $311.6 million on 7.7 MMBbls of forecasted NGL forward sales transactions and equivalent PTR volumes extending through December 2012. Our estimates of future gross margins are subject to various business risks, including unforeseen production outages or declines, counterparty risk, or similar events or developments that are outside of our control.

§	The objective of our NGL, refined products and crude oil sales hedging program is to hedge the margins of anticipated future sales of inventory by locking in sales prices through the use of forward physical sales contracts and commodity derivative instruments.

112

Table of Contents

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

Certain basis swaps, basis spread options and other derivative instruments not designated as hedging instruments are used to manage market risks associated with anticipated purchases and sales of natural gas necessary to optimize our owned and contractually committed transportation and storage capacity.

There is some uncertainty involved in the timing of these transactions often due to the development of more favorable profit opportunities or when spreads are insufficient to cover variable costs thus reducing the likelihood that the transactions will occur as originally forecasted. As a result of this timing uncertainty, these derivative instruments do not qualify for hedge accounting even though they are effective at managing the risk exposures of these assets.

The earnings volatility caused by fluctuations in non-cash, mark-to-market earnings cannot be predicted and the impact to earnings could be material.

The following table summarizes our commodity derivative instruments outstanding at December 31, 2011:

	Volume (1)		Accounting
Derivative Purpose	Current (2)	Long-Term (2)	Treatment
Derivatives designated as hedging instruments:
Natural gas processing:

(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 2013, May 2012 and December 2013, respectively. (3) PTR represents the British thermal unit equivalent of the NGLs extracted from natural gas by a processing plant, and includes the natural gas used as plant fuel to extract those liquids, plant flare and other shortages. (4) Forecasted sales of NGL volumes under natural gas processing exclude 2.2 MMBbls of additional hedges executed under contracts that have been designated as normal sales agreements. (5) Current volumes include approximately 87.8 Bcf of physical derivative instruments that are predominantly priced at an index plus a premium or minus a discount related to location differences. (6) Reflects the use of derivative instruments to manage risks associated with transportation, processing and storage assets.

MANAGEMENT’S ANNUAL REPORT ON INTERNAL CONTROL

OVER FINANCIAL REPORTING AS OF DECEMBER 31, 2011

The management of Enterprise Products Partners L.P. and its consolidated subsidiaries, including its chief executive officer and chief financial officer, is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Rules 13a-15(f) and 15d-15(f) of the Securities Exchange Act of 1934, as amended. Our internal control system was designed to provide reasonable assurance to the management of Enterprise Products Partners L.P. and the Board of Directors of its general partner regarding the preparation and fair presentation of Enterprise Products Partners L.P.’s published financial statements.

Our management assessed the effectiveness of Enterprise Products Partners L.P.’s internal control over financial reporting as of December 31, 2011. In making this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) in Internal Control—Integrated Framework . This assessment included a review of the design and operating effectiveness of internal controls over financial reporting as well as the safeguarding of assets. Based on our assessment, we believe that, as of December 31, 2011, Enterprise Products Partners L.P.’s internal control over financial reporting is effective based on those criteria.

Our Audit and Conflicts Committee is composed of independent directors who are not officers or employees of our general partner. This committee meets regularly with members of management, Internal Audit and representatives of Deloitte & Touche LLP, our independent registered public accounting firm, to discuss the adequacy of Enterprise Products Partners L.P.’s internal controls over financial reporting, financial statements and the nature, extent and results of the audit effort. Management reviews all of Enterprise Products Partners L.P.’s significant accounting policies and assumptions affecting the results of operations with the Audit and Conflicts Committee. Both the independent registered public accounting firm and internal auditors have direct access to the Audit and Conflicts Committee without the presence of management.

Deloitte & Touche LLP has issued its attestation report (the “Report of Independent Registered Public Accounting Firm”) regarding our internal control over financial reporting. That report is included within this Item 9A .

Pursuant to the requirements of Rules 13a-15(f) and 15d-15(f) of the Securities Exchange Act of 1934, as amended, this annual report on Internal Control Over Financial Reporting has been signed below by the following persons on behalf of the registrant and in the capacities indicated below on February 29, 2012.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors of Enterprise Products Holdings LLC and the

Unitholders of Enterprise Products Partners L.P.

Houston, Texas

We have audited the internal control over financial reporting of Enterprise Products Partners L.P. and subsidiaries (the “Company”) as of December 31, 2011, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Annual Report on Internal Control over Financial Reporting as of December 31, 2011. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company’s internal control over financial reporting is a process designed by, or under the supervision of, the company’s principal executive and principal financial officers, or persons performing similar functions, and effected by the company’s Board of Directors, management, and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of the inherent limitations of internal control over financial reporting, including the possibility of collusion or improper management override of controls, material misstatements due to error or fraud may not be prevented or detected on a timely basis. Also, projections of any evaluation of the effectiveness of the internal control over financial reporting to future periods are subject to the risk that the controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2011, based on the criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.

PART III

Item 10. Directors, Executive Officers and Corporate Governance .

Partnership Management

As is commonly the case with publicly traded limited partnerships, we do not directly employ any of the persons responsible for our management, administrative or operating functions. Pursuant to the ASA, these roles are performed by employees of EPCO, which are under the direction of the Board of Directors (the “Board”) and executive officers of Enterprise GP. For a description of the ASA, see “Relationship with EPCO and Affiliates — EPCO ASA” under Note 15 of the Notes to Consolidated Financial Statements included under Item 8 of this annual report.

The executive officers of Enterprise GP are elected for one-year terms and may be removed, with or without cause, only by the Board. Our unitholders do not elect the officers or directors of Enterprise GP. The DD LLC Trustees, through their control of Enterprise GP, have the ability to elect, remove and replace at any time, all of the officers and directors of our general partner. Each member of the Board of Enterprise GP serves until such member’s death, resignation or removal. The employees of EPCO who served as directors of our general partner during 2011 were Messrs. Bachmann, Creel, Cunningham, Fowler and Teague and Ms. Williams.

Notwithstanding any contractual limitation on its obligations or duties, Enterprise GP is liable for all debts we incur (to the extent not paid by us), except to the extent that such indebtedness or other obligations are non-recourse to Enterprise GP. Whenever possible, Enterprise GP intends to make any such indebtedness or other obligations non-recourse to itself.

Under our limited partnership agreement and subject to specified limitations, we will indemnify to the fullest extent permitted by Delaware law, from and against all losses, claims, damages or similar events, any director or officer, or while serving as director or officer, any person who is or was serving as a tax matters member or as a director, officer, tax matters member, employee, partner, manager, fiduciary or trustee of our partnership or any of our affiliates. Additionally, we will indemnify to the fullest extent permitted by law, from and against all losses, claims, damages or similar events, any person who is or was an employee (other than an officer) or agent of our general partner.

Corporate Governance

We are committed to sound principles of governance. Such principles are critical for us to achieve our performance goals and maintain the trust and confidence of investors, employees, suppliers, business partners and stakeholders.

A key element for strong governance is independent members of the Board. Pursuant to the NYSE listing standards, a director will be considered independent if the Board determines that he or she does not have a material relationship with Enterprise GP or us (either directly or as a partner, unitholder or officer of an organization that has a material relationship with Enterprise GP or us). Based on the foregoing, the Board has affirmatively determined that Messrs. Andress, Barnett, Casey, McMahen, Ross, Smith and Snell are “independent” directors under the NYSE rules.

Because we are a limited partnership and meet the definition of a “controlled company” under the listing standards of the NYSE, we are not required to comply with certain requirements of the NYSE. In particular, we are not required to comply with Section 303A.01 of the NYSE Listed Company Manual, which would require that the Board of our general partner be comprised of a majority of independent directors. In addition, we have elected to not comply with Sections 303A.04 and 303A.05 of the NYSE Listed Company Manual, which would require that the Board of Enterprise GP maintain a Nominating Committee and a Compensation Committee, each consisting entirely of independent directors.

Code of Conduct and Ethics and Corporate Governance Guidelines

Enterprise GP has adopted a “Code of Conduct” that applies to its directors, officers and employees. This code sets out our requirements for compliance with legal and ethical standards in the conduct of our business, including general business principles, legal and ethical obligations, compliance policies for specific subjects, obtaining guidance on complying with the code, the reporting of compliance issues, and discipline for violations of the code. The Code of Conduct also establishes policies applicable to our CEO, CFO, principal accounting officer and senior financial and other managers to prevent wrongdoing and to promote honest and ethical conduct, including ethical handling of actual and apparent conflicts of interest, compliance with applicable laws, rules and regulations, full, fair, accurate, timely and understandable disclosure in public communications, and prompt internal reporting of violations of the code (and thus accountability for adherence to the code). Employees are required to periodically certify their understanding and compliance with the Code of Conduct.

Governance guidelines, together with applicable committee charters, provide the framework for effective governance. The Board has adopted the “Governance Guidelines of Enterprise Products Partners,” which address several matters, including qualifications for directors, responsibilities of directors, retirement of directors, the composition and responsibilities of the Audit and Conflicts Committee (the “Audit Committee”) and the Governance Committee, the conduct and frequency of Board and committee meetings, management succession plans, director access to management and outside advisors, director compensation, director and executive officer equity ownership, director orientation and continuing education, and annual self-evaluation of the Board. The Board recognizes that effective governance is an on-going process, and thus, it will review the Governance Guidelines of Enterprise Products Partners annually or more often as deemed necessary.

Audit Committee

The purpose of the Board’s Audit Committee is to address audit and conflicts-related matters. In accordance with NYSE rules and the Securities Exchange Act of 1934, the Board has named three of its members to serve on its Audit Committee. The members of the Audit Committee must have a basic understanding of finance and accounting matters and be able to read and understand fundamental financial statements, and at least one member of the Audit Committee shall have accounting or related financial management expertise. The current members of the Audit Committee are Messrs. McMahen (chairman), Ross and Snell, all of whom are independent directors, free from any relationship with us or any of our subsidiaries that would interfere with the exercise of independent judgment. The Board has affirmatively determined that Mr. McMahen satisfies the definition of “audit committee financial expert” as defined in Item 407(d) of Regulation S-K promulgated by the SEC.

119

Table of Contents

The primary responsibilities of the Audit Committee include (i) reviewing potential conflicts of interest, including related party transactions, (ii) monitoring the integrity of our financial reporting process and related systems of internal control, (iii) ensuring our legal and regulatory compliance and that of Enterprise GP, (iv) overseeing the independence and performance of our independent public accountant, (v) approving all services performed by our independent public accountant, (vi) providing for an avenue of communication among the independent public accountant, management, internal audit function and the Board, (vii) encouraging adherence to and continuous improvement of our policies, procedures and practices at all levels, (viii) reviewing areas of potential significant financial risk to our businesses and (ix) approving awards granted under our long-term incentive plans.

If the Board believes that a particular matter presents a conflict of interest and proposes a resolution, the Audit Committee has the authority to review such matter to determine if the proposed resolution is fair and reasonable to us. Any matters approved by the Audit Committee are conclusively deemed to be fair and reasonable to our business, approved by all of our partners and not a breach by Enterprise GP or the Board of any duties they may owe us or our unitholders.

Pursuant to its formal written charter, the Audit Committee has the authority to conduct any investigation appropriate to fulfilling its responsibilities, and it has direct access to our independent public accountants as well as any EPCO personnel whom it deems necessary in fulfilling its responsibilities. The Audit Committee has the ability to retain, at our expense, special legal, accounting or other consultants or experts it deems necessary in the performance of its duties.

Governance Committee

The Governance Committee was established by the Board in May 2011. In accordance with its charter, the Governance Committee shall be composed of not less than three members, at least a majority of whom shall be independent directors. Currently, the Governance Committee is comprised of four independent directors: Messrs. Andress, Barnett (chairman), Casey and Smith. The primary purpose of the Board’s Governance Committee is to develop and recommend to the Board a set of governance guidelines applicable to our partnership, to review such guidelines from time to time and to oversee governance matters related to our business, including Board and Committee composition, qualifications of Board candidates, director independence, succession planning and other related matters. Prior to the establishment of the Governance Committee, these responsibilities were generally handled by the Audit Committee, which was then known as the Audit, Conflicts and Governance Committee.

The Governance Committee was also established to assist in Board oversight of management’s establishment and administration of our environmental, health and safety policies, procedures, programs and initiatives, and other related matters.

Like the Audit Committee, the Governance Committee has the authority to conduct any investigation appropriate to fulfilling its responsibilities, and it has direct access to our independent public accountants as well as any EPCO personnel whom it deems necessary in fulfilling its responsibilities. In addition, the Governance Committee has the ability to retain, at our expense, special legal, accounting or other consultants or experts it deems necessary in the performance of its duties.

NYSE Corporate Governance Listing Standards

On March 8, 2011, Mr. Creel, our CEO, certified to the NYSE (as required by Section 303A.12(a) of the NYSE Listed Company Manual) that he was not aware of any violation by us of the NYSE’s Corporate Governance listing standards as of March 8, 2011.

Executive Sessions of Non-Management Directors

The Board holds regular executive sessions in which non-management directors meet without any members of management present. The purpose of these executive sessions is to promote open and candid discussion among the non-management directors. During such executive sessions, one director is designated as the “presiding director,” who is responsible for leading and facilitating such executive sessions. Currently, the presiding director is Mr. McMahen.

In accordance with NYSE rules, we have established a toll-free, confidential telephone hotline (the “Hotline”) so that interested parties may communicate with the presiding director or with all the non-management directors as a group. All calls to this Hotline are reported to the chairman of the Audit Committee, who is responsible for communicating any necessary information to the other non-management directors. The number of our confidential Hotline is (877) 888-0002.

Compensation Discussion and Analysis

With respect to our named executive officers, compensation paid or awarded by us for the last three fiscal years reflects only that portion of compensation paid by EPCO and allocated to us pursuant to the ASA, including an allocation of a portion of the cost of equity-based long-term incentive plans of EPCO. The EPCO Trustees control EPCO and provide recommendations with respect to the compensation of our CEO. As discussed further below, the Audit Committee of our general partner was given ultimate decision-making authority with respect to 2011 compensation to be paid to our CEO, and our CEO was given ultimate decision-making authority with respect to 2011 compensation to be paid to our other named executive officers. The following elements of compensation, and EPCO’s decisions with respect to determination of payments, are not subject to approvals by the Board or the Audit Committee of our general partner, except in the case of compensation paid to our CEO (as described below). Neither EPCO nor our general partner has a separate compensation committee; however, equity awards granted under EPCO’s long-term incentive plans are approved by the Audit Committee.

As discussed below, the elements of EPCO’s compensation program, along with EPCO’s other incentives (e.g., benefits, work environment and career development), are intended to provide a total rewards package to employees. The objectives of EPCO’s compensation program are to provide competitive compensation opportunities that will align and drive employee performance toward the creation of sustained long-term unitholder value. Our compensation program allows us to attract, motivate and retain high quality talent with the skills and competencies we require. The compensation package is designed to reward contributions by employees in support of the business strategies of EPCO and its affiliates at both our partnership and individual levels. With respect to the three years ended December 31, 2011, EPCO’s compensation package for named executive officers did not include any elements based on targeted performance-related criteria.

129

Table of Contents

The primary elements of EPCO’s compensation program are a combination of annual cash and long-term equity-based incentive compensation. For the three years ended December 31, 2011, the elements of compensation for the named executive officers consisted of annual cash base salary, discretionary annual cash bonus awards, awards under long-term incentive arrangements and other compensation, including very limited perquisites.

In order to assist our CEO, EPCO and the Audit Committee with compensation decisions, EPCO’s senior vice president of Human Resources formulates preliminary compensation recommendations for each of the named executive officers, including our CEO. With respect to compensation to be paid to our CEO, the EPCO Trustees consider such preliminary recommendation and make revisions, if appropriate. Afterwards, the EPCO Trustees and EPCO’s senior vice president of Human Resources present the revised CEO compensation recommendation to the members of the Audit Committee, which consider the recommendation and then make a final determination regarding compensation of our CEO. In making their final determination, the Audit Committee may discuss the recommendation with EPCO’s senior vice president of Human Resources, request to discuss the recommendations with EPCO’s compensation consultant, if any, and/or retain its own compensation consultant.

With respect to compensation to be paid to named executive officers other than our CEO, the CEO considers the preliminary recommendations of EPCO’s senior vice president of Human Resources and makes revisions, if appropriate. The CEO makes a final determination regarding compensation of each named executive officer (other than the CEO himself).

In making these compensation decisions, EPCO considers market data for determining relevant compensation levels and compensation program elements through the review of and, in certain cases, participation in, relevant compensation surveys and reports. These surveys and reports are conducted and prepared by a third-party compensation consultant.

In 2011, EPCO engaged Meridian Compensation Partners, LLC (the “Consultant”) to review executive compensation relative to our industry. The Consultant provided comparative market data on compensation practices and programs for executive level positions based on an analysis of industry competitors and other large companies. The market data for industry competitors included information from Atmos Energy Corporation; CenterPoint Energy, Inc.; CMS Energy Corporation; Constellation Energy Group, Inc.; Dominion Resources, Inc.; El Paso Corporation; Enbridge Energy Partners, L.P.; Energy Transfer Partners, L.P.; NiSource Inc.; NuStar Energy L.P.; ONEOK, Inc.; Plains All American Pipeline, L.P.; Spectra Energy Corp.; The Williams Companies, Inc.; and TransCanada Corporation. The market data for other large companies included 51 entities across multiple industries ranging in revenue size from $80 billion to $15 billion, including well known companies such as The Procter & Gamble Company; The Home Depot, Inc.; Archer Daniels Midland Company; Target Corporation; and The Boeing Company, among others.

Neither we, nor EPCO, which engages the Consultant, are aware of the specific data of the companies included in the Consultant’s proprietary database for specific positions. EPCO uses the information provided in the Consultant’s analysis to gauge whether compensation levels reported by the Consultant and the general ranges of compensation for EPCO employees in similar positions are comparable, but that comparison is only a factor taken into consideration and may or may not impact compensation of our named executive officers, for which our Audit Committee (in the case of our CEO’s compensation) or our CEO (in the case of compensation to be paid to our other named executive officers) has the ultimate decision-making authority. EPCO does not otherwise engage in benchmarking for the named executive officers’ positions.

The Audit Committee, our CEO and EPCO do not use any formula or specific performance-based criteria in determining the compensation of our named executive officers for services they perform for us; rather, the Audit Committee or our CEO (as applicable) and EPCO determine an appropriate level and mix of compensation on a case-by-case basis. Further, there is no established policy or target for the allocation between either cash and non-cash or short-term and long-term incentive compensation. However, some considerations that the Audit Committee or our CEO (as applicable) may take into account in making the case-by-case compensation determinations include total value of all elements of compensation and the appropriate balance of internal pay equity among executive officers. The Audit Committee, our CEO and EPCO also consider individual performance, levels of responsibility and value to the organization. All compensation determinations are subjective and discretionary and, as noted above, subject to the ultimate decision-making authority of the Audit Committee or the CEO (as applicable), except

130

Table of Contents

for equity awards under EPCO’s long-term incentive plans, as discussed below.

We believe that the absence of specific performance-based criteria associated with our cash compensation and equity awards, and the long-term nature of our equity awards, has the effect of discouraging excessive risk taking by our executive officers in order to reach certain targets. Further, the practice of making compensation decisions on a case-by-case basis permits consideration of flexible criteria, including current overall market conditions.

Base salaries of our named executive officers prior to 2010 were previously determined by Mr. Duncan without consultation with the Audit Committee. During 2010 and 2011, changes in the base salaries of our named executive officers were largely budget-driven and made consistent relative to increases in the base salaries of our other executive officers.

The discretionary cash bonus awards paid to each of our named executive officers with respect to 2010 and 2011 were determined by consultation, as appropriate, among the EPCO Trustees, our CEO and EPCO’s senior vice president of Human Resources, subject to final determination by the Audit Committee (in the case of our CEO’s cash bonus awards) and our CEO (in the case of cash bonus awards to be paid to our other named executive officers). These cash bonus awards, in combination with annual base salaries, are intended to yield competitive total cash compensation levels for the named executive officers and drive performance in support of our business strategies, as well as the performance of other EPCO affiliates for which the named executive officers may perform services. It is EPCO’s general policy to pay these awards in February of the following year. For 2010 and 2011, the discretionary cash bonuses reflected the Audit Committee’s (with respect to our CEO) and our CEO’s (with respect to the other named executive officers) general consideration of our financial performance for those periods, without any weight or formula given to any specific financial performance measures, as well as their subjective judgment of each named executive officer’s general contributions in connection with our performance, again without any weight or formula given to any specific individual contribution or accomplishments. The levels of cash bonuses were also based on the level and position of such named executive officers and the relative compensation paid to our other executive officers.

The awards granted under EPCO’s long-term incentive plans to our named executive officers during 2010 and 2011 were determined by consultation among the EPCO Trustees, our CEO and EPCO’s senior vice president of Human Resources, and were approved by the Audit Committee. The levels of EPCO’s long-term incentive plan awards to our named executive officers during 2010 and 2011 also reflected the Audit Committee’s and our CEO’s (with respect to the other named executive officers) general consideration of our financial performance for those periods, without any weight or formula given to any specific financial performance measures, as well as their subjective judgment of each named executive officer’s general contributions in connection with our performance, again without any weight or formula given to any specific individual contribution or accomplishments. The levels of long-term incentive awards were also based on the level and position of such named executive officers and the relative compensation paid to our other executive officers.

EPCO expects to continue its policy of paying for limited perquisites attributable to our named executive officers. EPCO also makes matching contributions under its defined contribution plans for the benefit of our named executive officers in the same manner as it does for other EPCO employees.

EPCO does not offer our named executive officers a defined benefit pension plan. Also, none of our named executive officers had nonqualified deferred compensation during the three years ended December 31, 2011.

In August 2010, the Employee Partnerships were liquidated with the consent of EPCO (in its capacity as the general partner of each Employee Partnership) and the Class A and Class B limited partners thereof, in accordance with the terms of each Employee Partnership's partnership agreement. Upon the liquidation of each Employee Partnership, the assets of such Employee Partnership were distributed to the Class A and B limited partners thereof. As a result, the Class B limited partners of each Employee Partnership, which included our named executive officers, received a liquidating distribution in 2010 of partnership assets consisting of limited partner interests in either us or Holdings.

In the fourth quarter of 2010, EPCO entered into retention agreements with each of the named executive

131

Table of Contents

officers to reinforce and encourage the continued dedication of such officers to EPCO and us as a member of our executive management team and to assure that we and EPCO will have the services of the executives in the foreseeable future. Pursuant to the retention agreements, Messrs. Creel, Fowler, Teague, Ordemann and Bourdon will be entitled to a cash retention payment of $10 million, $5 million, $10 million, $2.5 million and $2.5 million, respectively, less applicable withholding taxes (as applicable to each person, the “Retention Payment”) following the completion of 48 months of continuous employment with EPCO from the effective date of each retention agreement (the “Retention Period”). We record an allocated portion of such costs based on the approximate amount of time each officer spends on our consolidated business activities. The effective date of the retention agreements for Mr. Creel, Mr. Fowler and Mr. Teague was December 1, 2010. The effective date of the retention agreements for Mr. Ordemann and Mr. Bourdon was October 1, 2010.

Notwithstanding the required Retention Period, if at any time between 24 months and 48 months after December 1, 2010 (i.e., the period of continuous employment from December 1, 2010 until such time being referred to as the “Performance Period”), Mr. Teague designates a candidate to serve as Chief Operating Officer of Enterprise GP and such candidate is determined by the Audit Committee to be satisfactory and is hired by EPCO, then Mr. Teague will be entitled to a cash performance payment of the greater of (a) $6 million or (b) $10 million times (i) the number of months of Mr. Teague’s Performance Period, divided by (ii) 48 (the “Performance Payment”). Pursuant to his retention agreement, Mr. Teague is eligible to earn and receive either the Performance Payment or the Retention Payment, but not both.

Notwithstanding the Retention Period described above, each of the named executive officers will receive, or in the event of his death, his designated beneficiary will receive, unless otherwise required by law, his applicable Retention Payment in the event of an involuntary termination of his employment prior to the end of his Retention Period for specified reasons, including death, disability or termination of his employment by EPCO other than for “cause” (as defined in the applicable retention agreement) in connection with his job elimination, a business reorganization, or a sale of EPCO or us. The Retention Payment is payable in full within 30 days of such qualifying termination. In the event the named executive officer is paid his Retention Payment in connection with an involuntary termination as described above, he agrees that, for a period equal to the lesser of (i) 18 months after the date of the event which gives rise to the Retention Payment or (ii) the remainder of the Retention Period (as if the retention agreement were in full force and effect for the full Retention Period), he will not solicit or induce, either directly or indirectly, any of our employees to cease employment with EPCO.

Any Retention Payment or Performance Payment (with respect to Mr. Teague) is in addition to any discretionary incentive compensation that EPCO or any of its affiliates may, in its sole discretion, grant or have in place from time to time.

Although the retention agreements, restricted common unit awards and unit option awards are entered into with EPCO, all or a portion of the compensation related to these agreements may be allocated to us in accordance with the ASA by and among EPCO, us and the other parties thereto.

We believe that each of the base salary, discretionary cash bonus awards, long-term incentive awards and retention agreements, as applicable, fit the overall compensation objectives of us and of EPCO and are designed to avoid risks that are likely to conflict with our risk management policies.

Grants of Plan-Based Awards in Fiscal Year 2011

The following table presents information concerning each grant of a plan-based award made to a named executive officer in 2011 for which we will be allocated by EPCO our pro rata share of the related expense under the ASA. The restricted common unit awards granted during 2011 were under EPCO’s long-term incentive plans. No option awards were granted during 2011. See the following section, “Summary of Long-Term Incentive Arrangements Underlying 2011 Award Grants,” for information regarding the long-term incentive plans under which these awards were granted.

(1) Amounts presented reflect that portion of grant date fair value allocable to us based on the average percentage of time each named executive officer spent on our consolidated businesses during 2011. Based on current allocations, we estimate that the consolidated compensation expense we record for each named executive officer with respect to these awards will approximate these amounts over the vesting period. The closing price of our common units on February 22, 2011 was $43.70 per unit. (2) Awards granted to the named executive officers during 2011 were made under either the Amended and Restated 2008 Enterprise Products Long-Term Incentive Plan (“2008 Plan”) or the Enterprise Products 1998 Long-Term Incentive Plan (“1998 Plan”).

The grant date fair value amounts presented in the table are based on certain assumptions and considerations made by management. See Note 5 of the Notes to Consolidated Financial Statements included under Item 8 of this annual report for additional information regarding our fair value assumptions made in connection with equity-based compensation.

Summary of Long-Term Incentive Arrangements Underlying 2011 Award Grants

The following information summarizes the principal types of awards granted to our named executive officers under EPCO’s long-term incentive plans during 2011. These plans provide for incentive awards to EPCO’s key employees who perform management, administrative or operational functions for us or our affiliates.

Awards granted under the 1998 Plan may be in the form of unit options, restricted common units, phantom units and distribution equivalent rights (“DERs”). Awards granted under the 2008 Plan may be in the form of unit options, restricted common units, phantom units, unit appreciation rights (“UARs”) and DERs. As of December 31, 2011, no phantom unit awards, UARs or associated DERs have been granted under the EPCO plans to the named executive officers.

Restricted common unit awards . Restricted common unit awards allow recipients to acquire our common units (at no cost to the recipient apart from service or other conditions) once a defined vesting period expires, subject to customary forfeiture provisions. For awards granted prior to 2010, the restrictions on such awards generally lapse four years from the date of grant. Beginning in 2010, new restricted common unit grants generally vest at a rate of 25% per year beginning one year after the grant date. The fair value of restricted common units is based on the market price per unit of our common units on the date of grant. For financial statement purposes, compensation expense is recognized based on the grant date fair value, net of an allowance for estimated forfeitures. Each recipient is also entitled to quarterly cash distributions equal to the product of the number of restricted common units outstanding for the participant and the quarterly cash distribution per common unit paid by us.

133

Table of Contents

Unit option awards . Non-qualified incentive options to purchase a fixed number of our common units may be granted to key employees of EPCO. When issued, the exercise price of each option grant may be no less than the market price of our common units on the date of grant. In general, options granted under the EPCO plans have a vesting period of four years from the date of grant and expire at the end of the calendar year following the year of vesting (e.g., an option that vested on May 29, 2011 will expire on December 31, 2012). However, unit options only become exercisable at certain times (typically February, May, August and November) during the calendar year following the year in which they vest.

The fair value of each unit option is estimated on the date of grant using the Black-Scholes option pricing model, which incorporates various assumptions including expected life of the option, risk-free interest rates, expected distribution yield on our common units, and expected price volatility of our common units. In general, our assumption of expected life of the options represents the period of time that the options are expected to be outstanding based on an analysis of our historical option activity. Our selection of the risk-free interest rate is based on published yields for U.S. government securities with comparable terms. The expected distribution yield and unit price volatility is estimated based on several factors, which include an analysis of historical price volatility and distribution yield over a period equal to the expected life of the option.

Potential Payments Upon Termination or Change-in-Control

Our named executive officers do not have any employment agreements that call for payment of termination or severance benefits or that provide for any payments in the event of a change in control of our general partner, Enterprise GP.

EPCO has entered into retention agreements with each of the named executive officers, which are described under “Compensation Discussion and Analysis” within this Item 11. Under these agreements, each such person will receive, or in the event of his death, his designated beneficiary will receive, unless otherwise required by law, his applicable Retention Payment (set forth previously) in the event of an involuntary termination of his employment prior to the end of his Retention Period for specified reasons, including death, disability or termination of his employment by EPCO other than for "cause" (as defined in each retention agreement) in connection with his job elimination, a business reorganization or a sale of EPCO or us.

Vesting of restricted unit awards and option awards under the 1998 Plan and the 2008 Plan are subject to acceleration upon a qualifying termination, including termination after a change of control of our general partner. Qualifying termination under such awards generally means a termination as an employee of EPCO or an affiliated group member (i) upon death, (ii) a qualifying long-term disability, (iii) a qualifying retirement, or (iv) within one year after a change of control (as defined), other than a termination for cause (as defined) or termination by such person that is not a qualifying termination for good reason (as defined). A change of control under these award agreements is generally defined to mean that Dan L. Duncan, his wife, descendants, heirs and/or legatees and/or distributees of Dan L. Duncan’s estate, and/or trusts (including, without limitation, one or more voting trusts) established for the benefit of his wife, descendants, heirs and/or legatees and/or distributees, collectively, cease, directly or indirectly, to control Enterprise GP.

136

Table of Contents

As of December 31, 2011, the estimated market value of unvested unit option awards that could be realized in connection with an accelerated vesting for a qualifying termination (calculated as the difference between the exercise prices of the underlying options and closing price of our common units on December 30, 2011 of $46.38 per unit, but without reflecting any allocation of compensation to other entities under the ASA), would have been the following for each of the named executive officers:


	Accelerated Option Value
Named Executive Officer:
Michael A. Creel (CEO)	$	6,415,800
W. Randall Fowler (CFO)		4,338,000
A. James Teague		4,520,400
William Ordemann		4,155,600
Lynn L. Bourdon, III		2,260,200

Although the retention agreements, restricted unit awards and unit option awards are entered into with EPCO, all or an allocated portion of the compensation related to these agreements may be charged to us in accordance with the ASA.

Compensation Committee Report

We do not have a separate compensation committee. In addition, we do not directly employ or compensate our named executive officers. Rather, under the ASA, we reimburse EPCO for the compensation of our executive officers. As described in Compensation Discussion and Analysis, decisions regarding the compensation of our named executive officers are made, as applicable, by EPCO, our CEO and the Audit Committee of our general partner.

In light of the foregoing, the Board has reviewed and discussed with management the Compensation Discussion and Analysis set forth above and determined that it be included in this annual report for the year ended December 31, 2011.

Compensation Committee Interlocks and Insider Participation

None of the directors or executive officers of our general partner served as members of the compensation committee of another entity that has or had an executive officer who served as a member of our Board during 2011. As previously noted, we do not have a separate compensation committee. As described in Compensation Discussion

and Analysis, decisions regarding the compensation of our named executive officers are made, as applicable, by EPCO, our CEO and the Audit Committee of our general partner.

Director Compensation

Neither we nor our general partner provide any additional compensation to employees of EPCO who serve as directors of our general partner. The independent directors of our general partner are compensated as follows: (i) each will receive a $75,000 annual cash retainer; (ii) if the individual serves as chairman of a committee of the Board, then he will receive an additional $15,000 in cash annually; (iii) each will receive a meeting fee of $1,500 in cash for each meeting of the Board attended; (iv) each will receive a meeting fee of $1,500 in cash for each meeting of a duly appointed committee of the Board attended, provided that he is duly elected or appointed to the committee; and (v) each will receive an annual grant of our common units having a fair market value, based on the closing price of such securities on the trading day immediately preceding the date of grant, of approximately $75,000.

The following table presents information regarding compensation paid to the independent directors of our general partner, including amounts paid to Messrs. Casey and Snell in connection with their service as independent directors of DEP GP prior to the Duncan Merger, during the year ended December 31, 2011.

(1) Mr. Barnett became chairman of our new Governance Committee on October 1, 2011. (2) The value of unit awards received by Messrs. Casey and Snell in 2011 was based on the annual director compensation arrangements of DEP GP, which provided for annual grants valued at approximately $40,000 per director. Messrs. Casey and Snell were elected directors of our general partner in September 2011. (3) Mr. McMahen serves as chairman of the Audit Committee. (4) Mr. McMahen received a one-time payment of $819,000 in January 2011 in recognition of his extraordinary efforts during 2010 and in connection with his surrender of certain UARs issued to him under a long-term incentive plan of Holdings. The underlying UARs were assumed by us in connection with the Holdings Merger and subsequently cancelled when Mr. McMahen surrendered the awards. (5) Mr. Rampacek resigned from the Board in September 2011.

As an honorary director, O.S. Andras receives $20,000 in cash annually for his services.

Duncan Family Interests, Inc. has pledged 65,000,000 of our common units that it owns as security under the credit facility of another affiliate of EPCO. This credit facility includes customary and other events of default relating to EPCO and certain of its affiliates, including us. Upon an event of default under this credit facility, a change in ownership of these units could ultimately result.

Equity Ownership Guidelines

In order to further align the interests and actions of our general partner’s directors and executive officers with our long-term interests and those of our general partner and other unitholders, the Board has adopted and approved certain equity ownership guidelines for our general partner’s directors and executive officers. Under these guidelines:

each non-management director of our general partner is required to own our common units having an aggregate value (as defined in the guidelines) of three times the dollar amount of such non-management director’s aggregate annual cash retainer for service on the Board paid for the most recently completed calendar year; and

§	each executive officer of our general partner is required to own our common units having an aggregate value (as defined in the guidelines) of three times the dollar amount of such executive officer’s aggregate annual base salary for the most recently completed calendar year.

Item 13 . Certain Relationships and Related Transactions, and Director Independence .

Certain Relationships and Related Transactions

We believe that the terms and provisions of our related party agreements are fair to us; however, such agreements and transactions may not be as favorable to us as we could have obtained from unaffiliated third parties. Additional information regarding our related party transactions is set forth in Note 15 of the Notes to Consolidated Financial Statements included under Item 8 of this annual report and incorporated by reference into this Item 13.

Review and Approval of Transactions with Related Parties

We consider transactions between us and our subsidiaries and unconsolidated affiliates, on the one hand, and our executive officers and directors (or their immediate family members), our general partner or its affiliates (including other companies owned or controlled by the DD LLC Trustees or the EPCO Trustees), on the other hand, to be related party transactions. As further described below, our Partnership Agreement sets forth procedures by which related party transactions and conflicts of interest may be approved or resolved by Enterprise GP or its Audit Committee. In addition, the Audit Committee charter, Enterprise GP’s written internal review and approval policies and procedures (or “management authorization policy”) and the amended and restated ASA with EPCO govern specified related party transactions, as further described below.

In accordance with its charter, the Audit Committee reviews and approves related party transactions:

§	pursuant to our Partnership Agreement or the limited liability company agreement of Enterprise GP, as such agreements may be amended from time to time;

§	in which an officer or director of Enterprise GP or any of our subsidiaries, or an immediate family member of such an officer or director, has a material financial interest or is otherwise a party;

§	when requested to do so by management or the Board;

§	with a value of $5 million or more (unless such transaction is equivalent to an arm’s length or third party transaction); or

§	that it may otherwise deem appropriate from time to time.

As discussed in more detail in “Directors, Executive Officers and Corporate Governance —Partnership Management,” “—Corporate Governance” and “—Audit Committee” within Item 10 of this annual report, at December 31, 2011, the Audit Committee was comprised of three directors: Charles E. McMahen, Rex C. Ross and Richard S. Snell. For the year ended December 31, 2011, the Audit Committee reviewed and approved only one related party transaction, namely the amendment and restatement of the ASA in September 2011.

Our management authorization policy generally requires Board approval for asset purchase or sales transactions and capital expenditures to the extent such transactions have a value in excess of $250 million. Any such transaction would typically also require Audit Committee review under its charter if such transaction is also a related party transaction.

142

Table of Contents

The ASA governs numerous day-to-day transactions between us, Enterprise GP and EPCO and its affiliates, including the provision by EPCO of administrative and other services to us and our reimbursement to EPCO of costs, without markup or discount, for those services. The ASA was reviewed, approved and recommended to the Board by our Audit Committee, and the Board also approved it upon receiving such recommendation. For a summary of the ASA, see Note 15 of the Notes to Consolidated Financial Statements included under Item 8 of this annual report.

Related party transactions that do not occur under the ASA and that are not reviewed by the Audit Committee, as described above, are subject to the management authorization policy. This policy, which applies to related party transactions as well as transactions with unrelated parties, specifies thresholds for our general partner’s officers and chairman of the Board to authorize various categories of transactions, including purchases and sales of assets, expenditures, commercial and financial transactions and legal agreements.

Partnership Agreement Standards for Audit Committee Review

Under our Partnership Agreement, whenever a potential conflict of interest exists or arises between our general partner or any of its affiliates, on the one hand, and us, any of our subsidiaries or any partner, on the other hand, any resolution or course of action by our general partner or its affiliates in respect of such conflict of interest is permitted and deemed approved by all of our partners, and will not constitute a breach of our Partnership Agreement or any agreement contemplated by such agreement, or of any duty stated or implied by law or equity, if the resolution or course of action is or, by operation of the Partnership Agreement is deemed to be, fair and reasonable to us; provided that, any conflict of interest and any resolution of such conflict of interest will be conclusively deemed fair and reasonable to us if such conflict of interest or resolution is (i) approved by a majority of the members of Enterprise GP’s Audit Committee (i.e., a “Special Approval” is granted) or (ii) on terms objectively demonstrable to be no less favorable to us than those generally being provided to or available from third parties.

The Audit Committee (in connection with its Special Approval process) is authorized in connection with its resolution of any conflict of interest to consider:

§	the relative interests of any party to such conflict, agreement, transaction or situation and the benefits and burdens relating to such interest;

§	the totality of the relationships between the parties involved (including other transactions that may be particularly favorable or advantageous to us);

§	any customary or accepted industry practices and any customary or historical dealings with a particular party;

§	any applicable generally accepted accounting or engineering practices or principles;

§	the relative cost of capital of the parties involved and the consequent rates of return to the equity holders of such parties; and

§	such additional factors as the Audit Committee determines in its sole discretion to be relevant, reasonable or appropriate under the circumstances.

The review and approval process of the Audit Committee, including factual matters that may be considered in determining whether a transaction is fair and reasonable to us, is generally governed by Section 7.9 of our Partnership Agreement. As discussed above, the Audit Committee’s Special Approval is conclusively deemed fair and reasonable to us under our Partnership Agreement.

143

Table of Contents

The level of review and work performed by the Audit Committee with respect to a given transaction varies depending upon the nature of the transaction and the scope of the Audit Committee’s obligation. Examples of functions the Audit Committee may, as it deems appropriate, perform in the course of reviewing a transaction include, but are not limited to:

§	assessing the business rationale for the transaction;

§	reviewing the terms and conditions of the proposed transaction, including consideration and financing requirements, if any;

§	assessing the effect of the transaction on our results of operations, financial condition, distributable cash flow, properties or prospects;

§	conducting due diligence, including interviews and discussions with management and other representatives and reviewing transaction materials and findings of management and other representatives;

§	considering the relative advantages and disadvantages of the transactions to the parties involved;

§	engaging third party financial advisors to provide financial advice and assistance, including fairness opinions if requested;

§	engaging legal advisors; and

§	evaluating and negotiating the transaction and recommending for approval or approving the transaction, as the case may be.

Nothing contained in our Partnership Agreement requires the Audit Committee to consider the interests of any party other than us. In the absence of the Audit Committee or our general partner acting in bad faith, the resolution, action or terms so made, taken or provided (including granting Special Approval) by the Audit Committee or our general partner with respect to such matter are deemed conclusive and binding on all persons (including all of our partners) and do not constitute a breach of Partnership Agreement, or any other agreement contemplated thereby, or a breach of any standard of care or duty imposed in our Partnership Agreement or under the Delaware Revised Uniform Limited Partnership Act or any other law, rule or regulation. Our Partnership Agreement provides that it is presumed that the resolution, action or terms made, taken or provided by the Audit Committee or our general partner were not made, taken or provided in bad faith, and in any proceeding brought by any limited partner or by or on behalf of such limited partner or any other limited partner or us challenging such resolution, action or terms, the person bringing or prosecuting such proceeding will have the burden of overcoming such presumption.

Director Independence

Each of the members of the Audit Committee, namely Messrs. McMahen, Ross and Snell, and each of the members of the Governance Committee, namely Messrs. Andress, Barnett, Casey and Smith, have been determined to be independent under the applicable NYSE listing standards and are independent under the rules of the SEC applicable to audit committees. For a discussion of independence standards applicable to the Board and factors considered by the Board in making its independence determinations, please refer to “—Corporate Governance” under Item 10 of this annual report.

Item 14 . Principal Accountant Fees and Services .

We have engaged Deloitte & Touche LLP, the member firms of Deloitte Touche Tohmatsu, and their respective affiliates (collectively, “Deloitte & Touche”) as our independent registered public accounting firm and principal accountants. The following table summarizes fees we paid Deloitte & Touche for independent auditing, tax and related services for each of the last two fiscal years (dollars in thousands):

	For Year Ended December 31,
	2011		2010
Audit Fees (1)	$	3,841	$	5,366
Audit-Related Fees (2)		5		6
Tax Fees (3)		--		--
All Other Fees (4)		--		20
(1) Audit fees represent amounts billed for each of the years presented for (i) the audit of our annual financial statements and internal controls over financial reporting, (ii) the review of our quarterly financial statements filed on Form 10-Q and (iii) those services normally provided by Deloitte & Touche in connection with our statutory and regulatory filings or engagements, including comfort letters, consents and other services related to SEC matters. This information is presented as of the latest practicable date for this annual report. (2) Audit-related fees represent amounts we were billed in each of the years presented for assurance and related services that are reasonably related to the performance of the annual audit or quarterly reviews and are not reported under the section labeled “Audit Fees.” We engaged Deloitte & Touche to perform certain assurance work related to the amendment of an environmental permit during the years ended December 31, 2011 and 2010. (3) Tax fees represent amounts we were billed in each of the years presented for professional services rendered in connection with tax compliance, tax advice and tax planning. No such services were rendered by Deloitte & Touche during the last two years. (4) All other fees represent amounts we were billed in each of the years presented for services not classifiable under the other categories listed in the table above. We engaged Deloitte & Touche to perform certain software consulting services during the year ended December 31, 2010.

The Audit Committee of our general partner has approved the use of Deloitte & Touche as our independent principal accountant. In connection with its oversight responsibilities, the Audit Committee has adopted a pre-approval policy regarding any services proposed to be performed by Deloitte & Touche. The pre-approval policy includes four primary service categories: Audit, Audit-related, Tax and Other.

In general, as services are required, management and Deloitte & Touche submit a detailed proposal to the Audit Committee discussing the reasons for the request, the scope of work to be performed, and an estimate of the fee to be charged by Deloitte & Touche for such work. The Audit Committee discusses the request with management and Deloitte & Touche, and if the work is deemed necessary and appropriate for Deloitte & Touche to perform, approves the request subject to the fee amount presented (the initial “pre-approved” fee amount). As part of these discussions, the Audit Committee must determine whether or not the proposed services are permitted under the rules and regulations concerning auditor independence under the Sarbanes-Oxley Act of 2002 as well as rules of the American Institute of Certified Public Accountants. If at a later date, it appears that the initial pre-approved fee amount may be insufficient to complete the work, then management and Deloitte & Touche must present a request to the Audit Committee to increase the approved amount and the reasons for the increase.

Under the pre-approval policy, management cannot act upon its own to authorize an expenditure for services outside of the pre-approved amounts. On a quarterly basis, the Audit Committee is provided a schedule showing Deloitte & Touche’s pre-approved amounts compared to actual fees billed for each of the primary service categories. The Audit Committee’s pre-approval process helps to ensure the independence of our principal accountant from management.

In order for Deloitte & Touche to maintain its independence, we are prohibited from using them to perform general bookkeeping, management or human resource functions, and any other service not permitted by the Public Company Accounting Oversight Board. The Audit Committee’s pre-approval policy also precludes Deloitte & Touche from performing any of these services for us.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors of Enterprise Products Holdings LLC and

Unitholders of Enterprise Products Partners L.P.

Houston, Texas

We have audited the accompanying consolidated balance sheets of Enterprise Products Partners L.P. and subsidiaries (the “Company”) as of December 31, 2011 and 2010, and the related statements of consolidated operations, comprehensive income, cash flows, and equity for each of the three years in the period ended December 31, 2011. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, such consolidated financial statements present fairly, in all material respects, the financial position of Enterprise Products Partners L.P. and subsidiaries at December 31, 2011 and 2010, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2011, in conformity with accounting principles generally accepted in the United States of America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the Company's internal control over financial reporting as of December 31, 2011, based on the criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 29, 2012 expressed an unqualified opinion on the Company's internal control over financial reporting.

The consolidated financial statements give effect to the merger of Enterprise GP Holdings L.P. with the Company on November 22, 2010, which has been accounted for as an equity transaction as described in Note 1.

On September 3, 2010, Enterprise GP Holdings L.P. (“Holdings”), Enterprise, Enterprise GP, Enterprise Products GP, LLC (“EPGP,” the former general partner of Enterprise) and Enterprise ETE LLC (“Holdings MergerCo,” a Delaware limited liability company and a wholly owned subsidiary of Enterprise) entered into a merger agreement (the “Holdings Merger Agreement”). On November 22, 2010, the Holdings Merger Agreement was approved by the unitholders of Holdings and the merger of Holdings with and into Holdings MergerCo and related transactions were completed, with Holdings MergerCo surviving such merger (collectively, we refer to these transactions as the “Holdings Merger”). Enterprise’s membership interests in Holdings MergerCo were subsequently contributed to EPO. As a result of completing the Holdings Merger, Enterprise GP, which had previously been the general partner of Holdings (“Holdings GP”), became Enterprise’s general partner. See Note 1 for additional information regarding the Holdings Merger.

On April 28, 2011, we, our general partner, EPD MergerCo LLC (“Duncan MergerCo,” a Delaware limited liability company and our wholly owned subsidiary), Duncan Energy Partners L.P. (“Duncan Energy Partners”) and DEP Holdings, LLC (“DEP GP,” the general partner of Duncan Energy Partners) entered into a definitive merger agreement (the “Duncan Merger Agreement”). On September 7, 2011, the Duncan Merger Agreement was approved by the unitholders of Duncan Energy Partners and the merger of Duncan MergerCo with and into Duncan Energy Partners and related transactions were completed, with Duncan Energy Partners surviving such merger as our wholly owned subsidiary (collectively, we refer to these transactions as the “Duncan Merger”). See Note 1 for additional information regarding the Duncan Merger.

Note 1 . Partnership Operations, Organization and Basis of Presentation

General

We are a publicly traded Delaware limited partnership, the common units of which are listed on the New York Stock Exchange (“NYSE”) under the ticker symbol “EPD.” We were formed in April 1998 to own and operate certain natural gas liquids (“NGLs”) related businesses of EPCO and are now a leading North American provider of midstream energy services to producers and consumers of natural gas, NGLs, crude oil, refined products and certain petrochemicals. Our 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 assets include approximately 50,600 miles of onshore and offshore pipelines; 190 MMBbls of storage capacity for NGLs, refined products and crude oil; and 14 Bcf of natural gas storage capacity.

We are 100% owned by our limited partners from an economic perspective. We are managed and controlled by Enterprise GP, which has a non-economic general partner interest in us. We, Enterprise GP, EPCO and Dan Duncan LLC are affiliates and under the collective common control of the DD LLC Trustees and the EPCO Trustees. We have no employees. All of our operating functions and general and administrative support services are provided by employees of EPCO pursuant to an administrative services agreement (the “ASA”) or by other service providers. See Note 15 for information regarding the ASA and other related party matters.

Completion of Duncan Merger

On September 7, 2011, the Duncan Merger Agreement was approved by the unitholders of Duncan Energy Partners and the merger of Duncan MergerCo and Duncan Energy Partners and related transactions were completed, with Duncan Energy Partners surviving such merger as our wholly owned subsidiary. Each issued and outstanding common unit of Duncan Energy Partners was cancelled and converted into the right to receive common units representing limited partner interests in Enterprise based on an exchange ratio of 1.01 Enterprise common units for each Duncan Energy Partners common unit. Enterprise issued 24,277,310 of its common units (net of fractional common units cashed out) as consideration in the Duncan Merger. No Enterprise common units were issued to Enterprise or its subsidiaries as merger consideration. Since we historically consolidated Duncan Energy Partners for financial reporting purposes, the Duncan Merger did not change the basis of presentation of our historical financial statements.

Impact of the Holdings Merger on the Basis of Presentation of Our

Consolidated Financial Statements

On November 22, 2010, the Holdings Merger Agreement was approved by the unitholders of Holdings and the merger of Holdings with Holdings MergerCo and related transactions were completed, with Holdings MergerCo surviving such merger. At the effective time of the Holdings Merger, Enterprise GP succeeded as Enterprise’s general partner, and each issued and outstanding unit representing limited partner interests in Holdings was cancelled and converted into the right to receive Enterprise common units based on an exchange ratio of 1.5 Enterprise common units for each Holdings unit. Enterprise issued an aggregate of 208,813,454 of its common units (net of fractional common units cashed out) as consideration in the Holdings Merger and, immediately after the merger, cancelled 21,563,177 of its common units previously owned by Holdings.

In connection with the Holdings Merger, Enterprise’s partnership agreement was amended and restated to provide for the cancellation of its general partner’s 2% economic interest and incentive distribution rights in Enterprise. In addition, a privately held affiliate of EPCO agreed to temporarily waive the regular quarterly cash distributions it would otherwise receive from us with respect to a certain number of our common units (the “Designated Units”) it owned over a five-year period after the merger closing date of November 22, 2010. The number of Designated Units to which the temporary distribution waiver applies is as follows for distributions paid or to be paid, if any, during the following calendar years: 30,610,000 during 2011; 26,130,000 during 2012; 23,700,000 during 2013; 22,560,000 during 2014; and 17,690,000 during 2015. Distributions paid to partners during calendar year 2011 excluded the initial 30,610,000 Designated Units; however, distributions to be paid, as applicable, to partners in calendar year 2012 (beginning with the February 2012 distribution) will exclude 26,130,000 Designated Units. As a result, the number of our distribution-bearing units increased by 4,480,000 units beginning with the February 2012 distribution and will increase in subsequent years as the number of Designated Units declines.

Prior to the Holdings Merger, Enterprise was a consolidated subsidiary of Holdings, which was Enterprise’s parent. Upon completion of the Holdings Merger, Holdings merged with and into a wholly owned subsidiary of Enterprise. The Holdings Merger resulted in Holdings being considered the surviving consolidated entity for accounting purposes, while Enterprise is the surviving consolidated entity for legal and reporting purposes. For accounting purposes, Holdings is deemed the acquirer of the noncontrolling interests in Enterprise that were previously recognized in Holdings’ consolidated financial statements (i.e., the acquisition of Enterprise’s limited partner interests that were owned by parties other than Holdings). While it was a publicly traded partnership, Holdings (NYSE, ticker symbol “EPE”) electronically filed its annual and quarterly consolidated financial statements with the SEC. You can access this information at www.sec.gov .

As a result of the Holdings Merger, Enterprise’s consolidated financial and operating results prior to November 22, 2010 have been presented as if it were Holdings from an accounting perspective (i.e., the financial statements of Holdings became the historical financial statements of Enterprise). The primary differences between Holdings’ and Enterprise’s consolidated results of operations were: (i) general and administrative costs incurred by Holdings and EPGP (Enterprise’s former general partner); (ii) equity in income of Holdings’ noncontrolling ownership interests in Energy Transfer Equity; and (iii) interest expense associated with Holdings’ debt. In addition, for periods prior to November 22, 2010, the net assets, income, cash distributions and contributions and other amounts attributable to Enterprise’s limited partner interests that were owned by third parties and related parties other than Holdings are presented as a component of noncontrolling interests. See Note 13 for additional information regarding noncontrolling interests.

Limited partner units outstanding and earnings per unit amounts presented in these consolidated financial statements for periods prior to the Holdings Merger have been retroactively adjusted to reflect the 1.5 to one unit-for-unit exchange that occurred in connection with the Holdings Merger. See Note 17 for additional information regarding our earnings per unit amounts.

Impact of the TEPPCO Merger on the Basis of Presentation of Our

Consolidated Financial Statements

On October 26, 2009, the related mergers of Enterprise and its wholly owned subsidiaries with TEPPCO and TEPPCO GP were completed. Under terms of the merger agreements, TEPPCO and TEPPCO GP became wholly owned subsidiaries of Enterprise, and each of TEPPCO’s unitholders, except for a privately held affiliate of EPCO, received 1.24 of our common units for each TEPPCO unit they owned. In total, we issued an aggregate of 126,932,318 common units and 4,520,431 Class B units (described below) as consideration in the TEPPCO Merger for both TEPPCO units and the TEPPCO GP membership interests. On October 27, 2009, our TEPPCO and TEPPCO GP equity interests were contributed to EPO, and TEPPCO and TEPPCO GP became wholly owned subsidiaries of EPO.

A privately held affiliate of EPCO exchanged a portion of its TEPPCO units, based on the 1.24 exchange ratio, for 4,520,431 of our Class B units in lieu of common units. The Class B units are not entitled to receive regular quarterly cash distributions for the first sixteen quarters following the closing date of the merger. The Class B units automatically convert into the same number of common units on the date immediately following the payment date for the sixteenth regular quarterly distribution following the closing date of the merger. The Class B units are entitled to vote together with the common units as a single class on partnership matters and, except for the payment of distributions, have the same rights and privileges as our common units.

Under the terms of the TEPPCO Merger agreements, Holdings received 1,331,681 of our common units and an increase in the capital account of EPGP to maintain its 2% general partner interest in us as consideration for 100% of the membership interests of TEPPCO GP.

For periods prior to the TEPPCO Merger, the former owners’ share of the income of TEPPCO and TEPPCO GP is a component of net income attributable to noncontrolling interests as reflected on our Statements of Consolidated Operations. Additionally, cash distributions paid to and cash contributions received from the limited partners of TEPPCO are reflected as a component of cash distributions paid to and cash contributions received from noncontrolling interests.

Impact of the Deconsolidation of Texas Offshore Port System on Our

Consolidated Financial Statements

In August 2008, we, including TEPPCO, together with Oiltanking Holding Americas, Inc. (“Oiltanking”) formed the Texas Offshore Port System partnership (“TOPS”). In April 2009, we and TEPPCO dissociated from TOPS. As a result, our operating costs and expenses and net income for the year ended December 31, 2009 include a non-cash charge of $68.4 million. This loss represents the forfeiture of our cumulative investment, including that of TEPPCO, in TOPS through the date of dissociation. Additionally, Oiltanking’s noncontrolling interests of $33.4 million were removed from our consolidated books and records. The impact on net income attributable to partners was approximately $8.7 million, as nearly all of this loss was absorbed by noncontrolling interests in consolidation.

In September 2009, we entered into a settlement agreement with certain affiliates of Oiltanking that resolved all disputes between the parties related to the business and affairs of the TOPS project. Our consolidated financial statements for the year ended December 31, 2009 include approximately $66.9 million of expense in connection with the payment of this cash settlement.

Note 2. Summary of Significant Accounting Policies

Allowance for Doubtful Accounts

Our allowance for doubtful accounts is determined based on specific identification and estimates of future uncollectible accounts, including those related to natural gas imbalances. Our procedure for estimating the allowance for doubtful accounts is based on: (i) historical experience with customers, (ii) the

F-11

Table of Contents

ENTERPRISE PRODUCTS PARTNERS L.P.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

perceived financial stability of customers based on our research and (iii) the levels of credit we grant to customers. In addition, we may increase the allowance for doubtful accounts in response to the specific identification of customers involved in bankruptcy proceedings and similar financial difficulties. On a routine basis, we review estimates associated with the allowance for doubtful accounts to ensure that we have recorded sufficient reserves to cover potential losses.

The following table presents our allowance for doubtful accounts activity for the periods presented:

	For Year Ended December 31,
	2011			2010			2009
Balance at beginning of period	$	18.4		$	16.8		$	17.7
Charged to costs and expenses		0.8			2.6			0.1
Acquisition-related additions and other		--			1.1			--
Deductions (1)		(5.8	)		(2.1	)		(1.0	)
Balance at end of period	$	13.4		$	18.4		$	16.8

(1) The 2011 deduction amount is primarily due to our reassessment of the allowance for doubtful accounts as a result of improved credit ratings of a significant customer, which reduced our exposure to potential uncollectibility.

See “Credit Risk Due to Industry Concentrations” in Note 19 for additional information.

Cash and Cash Equivalents

Cash and cash equivalents represent unrestricted cash on hand and highly liquid investments with original maturities of less than three months from the date of purchase.

Consolidation Policy

Our consolidated financial statements include our accounts and those of our majority-owned subsidiaries in which we have a controlling interest, after the elimination of all intercompany accounts and transactions. We also consolidate other entities and ventures in which we possess a controlling financial interest as well as partnership interests where we are the sole general partner of the partnership. We evaluate our financial interests in business enterprises to determine if they represent variable interest entities where we are the primary beneficiary. If such criteria are met, we consolidate the financial statements of such businesses with those of our own. Third party or affiliate ownership interests in our controlled subsidiaries are presented as noncontrolling interests. See Note 13 for information regarding noncontrolling interests.

If the entity is organized as a limited partnership or limited liability company and maintains separate ownership accounts, we account for our investment using the equity method if our ownership interest is between 3% and 50%, unless our interest is so minor that we have virtually no influence over the investee’s operating and financial policies. For all other types of investments, we apply the equity method of accounting if our ownership interest is between 20% and 50% and we exercise significant influence over the investee’s operating and financial policies. In consolidation, we eliminate our proportionate share of profits and losses from transactions with equity method unconsolidated affiliates to the extent such amounts remain on our Consolidated Balance Sheets (or those of our equity method investments) in inventory or similar accounts.

We account for investments using the cost method when our ownership interest in an entity does not provide us with significant influence or when we have virtually no influence over the investee’s operating and financial policies. At December 31, 2011, we did not have any investments accounted for using the cost method.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

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 it is believed to be only reasonably possible or remote.

For contingencies where an unfavorable outcome is reasonably possible and the impact would be material, we disclose the nature of the contingency and, if 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 18 for additional information regarding our contingencies.

Current Assets and Current Liabilities

We present, as individual captions in our Consolidated Balance Sheets, all components of current assets and current liabilities that exceed 5% of total current assets and liabilities, respectively.

Deferred Revenues

Amounts billed in advance of the period in which the service is rendered or product delivered are recorded as deferred revenue. At December 31, 2011 and 2010, deferred revenues totaled $122.7 million and $113.9 million, respectively, and were recorded as a component of other current and long-term liabilities, as appropriate, on our Consolidated Balance Sheets. See Note 4 for information regarding our revenue recognition policies.

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, foreign currencies and certain anticipated future transactions. To qualify for hedge accounting, the hedged item must expose us to risk and the related derivative instrument must reduce that exposure 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 or quarterly 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 of our physical forward derivative instruments, we apply the normal purchase/normal sale exception, whereby changes in the mark-to-market values of such derivatives are not recognized in income. As a result, the revenues and expenses associated with the physical derivative transactions are recognized during the period when volumes are physically delivered or received. Physical derivative instruments are evaluated for the probability of future delivery and are periodically back-tested once the

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

forecasted period has passed to determine whether similar contracts are probable of physically delivering in the future.

See Note 6 for additional information regarding our derivative instruments and related interest rate and commodity hedging activities.

Earnings Per Unit

Earnings per unit is based on the amount of net income attributable to limited partners and the weighted-average number of limited partner units outstanding during a period. See Note 17 for additional information regarding our earnings per unit amounts.

Environmental Costs

Environmental costs for remediation are accrued based on estimates of known remediation requirements. Such accruals are based on management’s best estimate of the ultimate cost to remediate a site and are adjusted as further information and circumstances develop. Those estimates may change substantially depending on information about the nature and extent of contamination, appropriate remediation technologies and regulatory approvals. Expenditures to mitigate or prevent future environmental contamination are capitalized. Ongoing environmental compliance costs are charged to expense as incurred. In accruing for environmental remediation liabilities, costs of future expenditures for environmental remediation are not discounted to their present value, unless the amount and timing of the expenditures are fixed or reliably determinable. At December 31, 2011, none of our estimated environmental remediation liabilities were discounted to present value since the ultimate amount and timing of cash payments for such liabilities were not readily determinable.

The following table presents the activity of our environmental reserves for the periods presented:

	For Year Ended December 31,
	2011			2010			2009
Balance at beginning of period	$	12.4		$	16.7		$	22.3
Charged to costs and expenses		9.3			2.8			1.9
Acquisition-related additions and other		1.0			0.9			--
Deductions		(10.4	)		(8.0	)		(7.5	)
Balance at end of period	$	12.3		$	12.4		$	16.7

At December 31, 2011 and 2010, $4.5 million and $3.7 million, respectively, of our environmental reserves were classified as current liabilities.

Equity-based Awards

See Note 5 for information regarding our accounting for equity-based awards.

Estimates

Preparing our consolidated financial statements in conformity with U.S. generally accepted accounting principles (“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.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Fair Value Information

The carrying amounts of cash and cash equivalents (including restricted cash), accounts receivable and accounts payable approximate their fair values based on their short-term nature. See Note 6 for fair value information associated with our derivative instruments.

The estimated total fair value of our fixed-rate long-term debt obligations, including current maturities, was approximately $15.76 billion and $12.91 billion at December 31, 2011 and 2010, respectively. The aggregate carrying value of these debt obligations was $14.33 billion and $12.03 billion at December 31, 2011 and 2010, respectively. These values are based on quoted market prices for such debt or debt of similar terms and maturities. 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. See Note 9 for summarized financial information of our investments accounted for using the equity method.

Impairment Testing for Goodwill

Our goodwill amounts are assessed for impairment (i) on a routine annual basis or (ii) when impairment indicators are present. If such indicators occur (e.g., the loss of a significant customer, technological obsolescence of assets, etc.), the estimated fair value of the reporting unit to which the goodwill is assigned is determined and compared to its carrying value. If the fair value of the reporting unit is less than its carrying value including associated goodwill amounts, a charge to earnings is recorded to reduce the carrying value of the goodwill to its implied fair value. See Note 6 for information regarding impairment charges related to goodwill during 2009.

Impairment Testing for Long-Lived Assets

Long-lived assets (including intangible assets with finite useful lives and property, plant and equipment) are reviewed for impairment when events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable.

Long-lived assets with carrying values that are not expected to be recovered through future cash flows are written-down to their estimated fair values. The carrying value of a long-lived asset is deemed not recoverable if it exceeds the sum of undiscounted cash flows expected to result from the use and eventual disposition of the asset. If the asset’s carrying value exceeds the sum of its undiscounted cash flows, a non-cash asset impairment charge equal to the excess of the asset’s carrying value over its estimated fair value is recorded. Fair value is defined as the price that would be received to sell an asset or be paid to transfer a liability in an orderly transaction between market participants at a specified measurement date. We measure fair value using market price indicators or, in the absence of such data, appropriate valuation techniques. See Note 6 for information regarding impairment charges related to long-lived assets during 2011, 2010 and 2009.

Impairment Testing for Unconsolidated Affiliates

We evaluate our equity method investments for impairment when events or changes in circumstances indicate that there is a loss in value of the investment attributable to an other than temporary decline. Examples of such events or changes in circumstances include continuing operating losses of the entity and/or long-term negative changes in the entity’s industry. In the event we determine that the loss in value of an investment is other than a temporary decline, we record a charge to equity earnings to adjust the carrying value of the investment to its estimated fair value. We had no such impairment charges during the periods presented.

Income Taxes

Publicly traded partnerships like ours are treated as corporations unless they have 90% or more in qualifying income (as that term is defined in the IRS Internal Revenue Code) and for the years ended December 31, 2011, 2010 and 2009, we had 90% or more of qualifying income. As a result, we are not subject to federal income tax. However, our partners are individually responsible for paying federal income taxes on their share of our taxable income. Net earnings for financial statement purposes may differ significantly from taxable income reportable to our unitholders as a result of differences between the tax basis and financial reporting basis of certain assets and liabilities and other factors. We do not have access to information regarding each partner’s individual tax basis in our limited partner interests.

See Note 16 for additional information regarding our provision for income taxes.

Inventories

Inventories primarily consist of NGLs, petrochemicals and refined products, crude oil and natural gas volumes that are valued at the lower of average cost or market. We capitalize, as a cost of inventory, shipping and handling charges (e.g., pipeline transportation and storage fees) and other related costs associated with purchased volumes. As volumes are sold and delivered out of inventory, the cost of these volumes (including freight-in charges that have been capitalized as part of inventory cost) are charged to operating costs and expenses. Shipping and handling fees associated with products we sell and deliver to customers are charged to operating costs and expenses as incurred. See Note 7 for additional information regarding our inventories.

Liquids Exchange Contracts

In total, our liquids exchange balances were payables of $301.7 million and $144.1 million December 31, 2011 and 2010, respectively. The most significant liquids exchange transactions recorded on our Consolidated Balance Sheets relate to those involving petrochemical volumes. Petrochemical transactions accounted for approximately 76% and 85% of our liquids exchange transactions recorded at December 31, 2011 and 2010, respectively. Under these agreements, we physically receive volumes of propane/propylene mix (an unprocessed stream), including the risk of loss and legal title to such volumes, from the exchange counterparty. In turn, we deliver segregated polymer grade propylene and propane (processed streams) back to the customer and charge them a processing or similar fee. The intent of these exchange transactions is the earning of fee revenue for processing and transporting the propane/propylene mix using our assets. This arrangement satisfies the commercial, logistical and timing needs of the customer and allows us to operate our plants more effectively.

To the extent that the aggregate volumes we receive under such exchange agreements exceed those we deliver under the agreements during a period (measured as of the end of each reporting period), we recognize a net exchange payable position with the counterparties. With respect to the petrochemical transactions discussed above, we are typically in a net exchange payable position with our counterparties. In those limited situations where the aggregate volumes we deliver exceed those we receive during a period (measured as of the end of each reporting period), we recognize a net exchange receivable position with the counterparties. From an income statement perspective, the only revenue recognized from such exchange agreements is fee revenue. From a balance sheet perspective, net exchange payables arising from these transactions are valued at market-based prices. To the extent that we recognize net exchange receivables arising from liquids exchange transactions, such balances are valued at average cost.

Volumetric receivables and payables arising from liquids exchange contracts are typically balanced with movements of products rather than with cash. When payment or receipt of monetary consideration is required for product differentials and service costs with a counterparty, such items are recognized in our Consolidated Financial Statements on a net basis as either operating revenues or expense, as appropriate.

Natural Gas Imbalances

In the natural gas pipeline transportation business, volumetric imbalances frequently result from differences in natural gas received from and delivered to customers. Such differences occur when a customer delivers more or less gas into our pipelines than is physically redelivered back to them during a particular time period. We have various fee-based agreements with customers to transport their natural gas through our pipelines. Our customers retain ownership of their natural gas shipped through our pipelines. As such, our pipeline transportation activities are not intended to create physical volume differences that would result in significant accounting or economic events for either our customers or us during the course of the agreement.

We settle pipeline gas imbalances with our customers through either (i) physical delivery of in-kind gas or (ii) in cash. These settlements follow contractual guidelines or common industry practices, including negotiated settlements. As imbalances occur, they may be settled: (i) on a monthly basis, (ii) at the end of the underlying transportation agreement or (iii) at other times in accordance with industry practice. The majority of such settlements are through in-kind arrangements whereby an imbalance volume is incrementally delivered to or received from a customer over several periods. However, certain of our natural gas pipelines have a regulated tariff rate mechanism requiring customer imbalance settlements each month at current market prices. In some cases, settlements of imbalances that built up over a period of time are ultimately cashed out at negotiated values which approximate average market prices over a period of time.

For natural gas imbalances to be settled over the next twelve months, we estimate the value of such current assets and liabilities (as applicable) using average market prices, which we believe are representative of the value of the imbalances upon final settlement. Changes in natural gas prices may impact our estimates. The following table presents our natural gas imbalance receivables and payables at the dates indicated:

	December 31,
	2011		2010
Natural gas imbalance receivables (1)	$	17.2	$	22.8
Natural gas imbalance payables (2)		24.0		31.9
(1) Reflected as a component of “Accounts receivable – trade” on our Consolidated Balance Sheets. (2) Reflected as a component of “Accrued product payables” on our Consolidated Balance Sheets.

Property, Plant and Equipment

Property, plant and equipment is recorded at cost. Expenditures for additions, improvements and other enhancements to property, plant and equipment are capitalized, and minor replacements, maintenance, and repairs that do not extend asset life or add value are charged to expense as incurred. When property, plant and equipment assets are retired or otherwise disposed of, the related cost and accumulated depreciation is removed from the accounts and any resulting gain or loss is included in results of operations for the respective period.

In general, depreciation is the systematic and rational allocation of an asset’s cost, less its residual value (if any), to the periods it benefits. The majority of our property, plant and equipment is depreciated using the straight-line method, which results in depreciation expense being incurred evenly over the life of an asset. Our estimate of depreciation expense incorporates management assumptions regarding the useful economic lives and residual values of our assets. With respect to midstream energy assets such as natural gas gathering systems that are reliant upon a specific natural resource basin for throughput volumes, the anticipated useful economic life of such assets may be limited by the estimated life of the associated natural resource basin from which the assets derive benefit. Our forecast of the remaining life for the applicable resource basins is based on several factors, including information published by the U.S. Energy Information Administration. Where appropriate, we use other depreciation methods (generally accelerated) for tax purposes.

F-17

Table of Contents

ENTERPRISE PRODUCTS PARTNERS L.P.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Leasehold improvements are recorded as a component of property, plant and equipment. The cost of leasehold improvements is charged to earnings using the straight-line method over the shorter of (i) the remaining lease term or (ii) the estimated useful lives of the improvements. We consider renewal terms that are deemed reasonably assured when estimating remaining lease terms.

Our assumptions regarding the useful economic lives and residual values of our assets may change in response to new facts and circumstances, which would prospectively impact our depreciation expense amounts. Examples of such circumstances include, but are not limited to: (i) changes in laws and regulations that limit the estimated economic life of an asset; (ii) changes in technology that render an asset obsolete; (iii) changes in expected salvage values or (iv) significant changes in the forecast life of the applicable resource basins, if any. See Note 8 for additional information regarding our property, plant and equipment.

Certain of our plant operations entail periodic planned outages for major maintenance activities. These planned shutdowns typically result in significant expenditures, which are principally comprised of amounts paid to third parties for materials, contract services and related items. We use the expense-as-incurred method for our planned major maintenance activities for plant operations; however, the cost of annual planned major maintenance projects are deferred and recognized ratably until the next planned outage. With regard to the planned major maintenance activities on our marine transportation assets, we use the deferral method to account for such costs. Under this method, major maintenance costs are capitalized and amortized over the period until the next major overhaul.

Asset retirement obligations (“AROs”) are legal obligations associated with the retirement of tangible long-lived assets that result from their acquisition, construction, development and/or normal operation. When an ARO is incurred, we record a liability for the ARO and capitalize an equal amount as an increase in the carrying value of the related long-lived asset. ARO amounts are measured at their estimated fair value using expected present value techniques. Over time, the ARO liability is accreted to its present value (accretion expense) and the capitalized amount is depreciated over the remaining useful life of the related long-lived asset. We will incur a gain or loss to the extent that our ARO liabilities are not settled at their recorded amounts.

Restricted Cash

Restricted cash represents amounts held in connection with our commodity derivative instruments portfolio and related physical natural gas, crude oil and NGL purchases. Additional cash may be restricted to maintain this portfolio as commodity prices fluctuate or deposit requirements change. At December 31, 2011 and 2010, our restricted cash amounts were $38.5 million and $98.7 million, respectively. See Note 6 for information regarding derivative instruments and hedging activities.

Revenue Recognition

In general, we recognize revenue from our customers when all of the following criteria are met: (i) persuasive evidence of an exchange arrangement exists, (ii) delivery has occurred or services have been rendered, (iii) the buyer’s price is fixed or determinable and (iv) collectibility is reasonably assured. See Note 4 for additional information regarding our revenue recognition policies.

Note 3. Recent Accounting Developments

Accounting standard setting organizations have been very active in recent years. Recently, they issued new and revised accounting guidance on a number of topics, including fair value measurements, presentation of comprehensive income, testing goodwill for impairment and balance sheet offsetting. We do not believe that adoption of this new guidance will have a material impact on our future Consolidated Financial Statements. The following paragraphs summarize these recent accounting developments:

Fair Value Measurements . In May 2011, the Financial Accounting Standards Board (or “FASB”) issued an accounting standard update that amended previous fair value measurement and disclosure guidance. These amendments generally involve clarifications on how to measure and disclose fair value amounts recognized in the financial statements. They also expand the disclosure requirements, particularly for Level 3 fair value measurements, to include a description of the valuation processes used and an analysis of the sensitivity of the fair value measurements to changes in unobservable inputs and the interrelationships between those unobservable inputs, if any. We adopted this guidance on January 1, 2012 and applied its requirements prospectively at that time.

Presentation of Comprehensive Income . In June 2011, the FASB issued an accounting standard update that revised the financial statement presentation of comprehensive income. The amended guidance requires entities to present components of comprehensive income in either (i) a single continuous statement of comprehensive income or (ii) two separate but consecutive statements (i.e., a statement of income and a statement of comprehensive income, which is our current format). Although the amended guidance does not change the items that must be reported in other comprehensive income, reclassification adjustments for each component of other comprehensive income would be displayed separately on the statement of income and in other comprehensive income. In December 2011, the FASB issued an accounting standard update to defer the requirement related to the separate presentation of reclassification adjustments.

Testing for Goodwill Impairment . In September 2011, the FASB issued an accounting standard update that provides entities with an option to perform a qualitative assessment to determine whether further impairment testing is necessary. We adopted this guidance on January 1, 2012.

Balance Sheet Offsetting . In December 2011, the FASB issued an accounting standard update enhancing the disclosure of financial instruments and derivative instruments that have been offset on the balance sheet or are subject to a master netting arrangement or similar agreement, regardless of whether they offset on the balance sheet. We will adopt this guidance on January 1, 2013 and apply its requirements retrospectively at that time.

Note 4. Revenue Recognition

The following information provides a general description of our underlying revenue recognition policies by business segment:

NGL Pipelines & Services

The NGL Pipelines & Services business segment includes our (i) natural gas processing business and related NGL marketing activities; (ii) NGL pipelines aggregating approximately 16,650 miles; (iii) NGL and related product terminal and storage facilities with approximately 156 million barrels (“MMBbls”) of net usable storage capacity; and (iv) 13 NGL fractionators. This segment also includes our import and export terminal operations.

delivered to the producer. Under keepwhole and margin-band contracts, we take ownership of mixed NGLs extracted from the producer’s natural gas stream and recognize revenue when the extracted NGLs are delivered and sold to customers under NGL marketing sales contracts. Revenue under our percent-of-liquids contracts is recognized the same way, except that the volume of NGLs we take ownership of is less than the total amount of NGLs extracted from the producers’ natural gas. Under a percent-of-liquids contract, the producer retains title to a percentage of the mixed NGLs we extract. Under a percent-of-proceeds contract, we share in the proceeds generated from the sale of the mixed NGLs we extract on the producer’s behalf.

Our NGL marketing activities generate revenue from the sale and delivery of NGLs we take title to through our natural gas processing activities and open market and contract purchases from third parties. Revenue from these sales contracts is recognized when the NGLs are delivered to customers. In general, sales prices referenced in these contracts are market-based and may include pricing differentials for factors such as delivery location.

Revenues from our NGL pipeline transportation contracts and tariffs are generally based upon a fixed fee per gallon of liquids transported multiplied by the volume delivered. Certain of our NGL pipelines offer firm capacity reservation services whereby the shipper pays a contractually stated fee based on the level of throughput capacity reserved in our pipelines whether or not the shipper actually utilizes such capacity. Revenues are recognized when volumes have been delivered to customers or in the period we provide firm capacity reservation services. Fees charged for NGL transportation services are either contractual or regulated by governmental agencies such as the Federal Energy Regulatory Commission (“FERC”).

We collect storage revenue under our NGL and related product storage contracts based on the number of days a customer has volumes in storage multiplied by a storage fee (as defined in each contract). Under these contracts, revenue is recognized ratably over the length of the storage period. With respect to capacity reservation agreements, we collect a fee for reserving storage capacity for certain customers in our underground storage wells. Under these agreements, revenue is recognized ratably over the specified reservation period. Excess storage fees are collected when customers exceed their reservation amounts and are recognized in the period of occurrence. We may also charge customers throughput fees based on volumes delivered into and subsequently withdrawn from storage, which are recognized as the service is provided.

We enter into fee-based arrangements (including a significant level of demand-based fees) and percent-of-liquids contracts for the NGL fractionation services we provide to customers. Under fee-based arrangements, revenue is recognized in the period services are provided. Such fee-based arrangements typically include a base-processing fee (usually stated in cents per gallon) that is contractually subject to adjustment for changes in certain fractionation expenses (e.g., natural gas fuel costs). Certain of our NGL fractionation facilities generate revenue using percent-of-liquids contracts. Such contracts allow us to retain a contractually determined percentage of the customer’s fractionated NGLs as payment for services rendered. Revenue is recognized from such arrangements when we sell and deliver the retained NGLs to customers.

Revenue from import and export terminaling activities is recorded in the period services are provided. Customers are typically billed a fee per unit of volume loaded or unloaded. With respect to our export terminal operations, revenue may also include demand payments charged to customers who reserve capacity at our export facilities and later fail to use such capacity. Demand fee revenue is recognized when the customer fails to utilize the specified export capacity as required by contract.

Onshore Natural Gas Pipelines & Services

The Onshore Natural Gas Pipelines & Services business segment includes approximately 20,200 miles of onshore natural gas pipeline systems that provide for the gathering and transportation of natural gas in Colorado, Louisiana, New Mexico, Texas and Wyoming. We lease salt dome natural gas storage

facilities located in Texas and Louisiana and own a salt dome storage cavern in Texas. This segment also includes our related natural gas marketing activities.

Our onshore natural gas pipelines typically generate revenues from transportation agreements under which shippers are billed a fee per unit of volume transported (typically per million British thermal units, or “MMBtus”) multiplied by the volume gathered or delivered. The transportation fees charged under these arrangements are either contractual or regulated by governmental agencies, including the FERC. Certain of our onshore natural gas pipelines offer firm capacity reservation services whereby the shipper pays a contractually stated fee based on the level of throughput capacity reserved in our pipelines whether or not the shipper actually utilizes such capacity. Revenues are recognized when volumes have been delivered to customers or in the period we provide firm capacity reservation services.

Under our natural gas storage contracts, there are typically two components of revenue: (i) monthly demand payments, which are associated with a customer’s storage capacity reservations and paid regardless of actual usage; and (ii) storage fees per unit of volume stored at our facilities. Revenue from demand payments is recognized during the period the customer reserves capacity. Revenue from storage fees is recognized in the period the services are provided.

Our natural gas marketing activities generate revenue from the sale and delivery of natural gas obtained from third party well-head purchases, regional natural gas processing plants and the open market. Revenue from these sales contracts is recognized when the natural gas is delivered to customers. In general, sales prices referenced in these contracts are market-based and may include pricing differentials for such factors as delivery location.

Onshore Crude Oil Pipelines & Services

The Onshore Crude Oil Pipelines & Services business segment includes approximately 5,250 miles of onshore crude oil pipelines and 12 MMBbls of above-ground storage tank capacity. This segment includes our crude oil marketing activities.

Revenue from crude oil transportation is generally based upon a fixed fee per barrel transported multiplied by the volume delivered. The transportation fees charged under these arrangements are either contractual or regulated by governmental agencies, including the FERC. Revenue associated with these arrangements is recognized when volumes have been delivered.

Under our crude oil terminaling agreements, we charge customers for crude oil storage based on the number of days a customer has volumes in storage multiplied by a contractual storage fee. Under these contracts, revenue is recognized ratably over the length of the storage period. With respect to storage capacity reservation agreements, we collect a fee for reserving storage capacity for customers at our terminals. Under these agreements, revenue is recognized ratably over the specified reservation period. In addition, we charge our customers throughput (or “pumpover”) fees based on volumes withdrawn from our terminals. Revenue is also generated from fee-based trade documentation services and is recognized as services are completed.

Our crude oil marketing activities generate revenue from the sale and delivery of crude oil obtained from producers or on the open market. These sales contracts generally settle with the physical delivery of crude oil to customers. In general, the sales prices referenced in these contracts are market-based and may include pricing differentials for such factors as delivery location or crude oil composition.

Offshore Pipelines & Services

The Offshore Pipelines & Services business segment serves some of the most active drilling and development regions, including deepwater production fields, in the northern Gulf of Mexico offshore Texas, Louisiana, Mississippi and Alabama. This segment includes approximately 1,330 miles of offshore natural gas pipelines, approximately 980 miles of offshore crude oil pipelines and six multi-purpose offshore hub platforms.

ENTERPRISE PRODUCTS PARTNERS L.P.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Revenue from our offshore pipelines is derived from fee-based agreements whereby the customer is charged a fee per unit of volume gathered or transported (typically per MMBtu of natural gas or per barrel of crude oil) multiplied by the volume delivered. Revenue associated with these fee-based contracts and tariffs is recognized when volumes have been delivered.

Revenues from offshore platform services generally consist of demand fees and commodity charges. Revenue from platform services is recognized in the period the services are provided. Demand fees represent charges to customers served by our offshore platforms regardless of the volume the customer actually delivers to the platform. Revenue from commodity charges is based on a fixed-fee per unit of volume delivered to the platform (typically per million cubic feet of natural gas or per barrel of crude oil) multiplied by the total volume of each product delivered. Contracts for platform services often include both demand fees and commodity charges, but demand fees generally expire after a contractually fixed period of time and in some instances may be subject to cancellation by customers. For example, the producers connected to our Independence Hub platform paid us approximately $54.6 million of demand fees annually from March 2007 through February 2012. These demand fees are in addition to commodity charges they pay us based on volumes delivered to the platform.

Petrochemical & Refined Products Services

The Petrochemical & Refined Products Services business segment includes (i) propylene fractionation plants, pipelines and related marketing activities; (ii) a butane isomerization facility and related pipeline system; (iii) octane enhancement and high purity isobutylene production facilities; (iv) refined products pipelines, including our Products Pipeline System, and related marketing activities; and (v) marine transportation assets and other services.

Our propylene fractionation and butane isomerization facilities generate revenue through fee-based arrangements, which typically include a base-processing fee per gallon (or other unit of measurement) subject to adjustment for changes in natural gas, electricity and labor costs, which are the primary costs of propylene fractionation and butane isomerization. Revenue resulting from such agreements is recognized in the period the services are provided.

Our petrochemical marketing activities include the purchase and fractionation of refinery grade propylene obtained in the open market and generate revenues from the sale and delivery of products obtained through propylene fractionation. Revenue from these sales contracts is recognized when such products are delivered to customers. In general, we sell our petrochemical products at market-based prices, which may include pricing differentials for such factors as delivery location.

Our refined products pipelines, including our Products Pipeline System, generate revenues through tariffs as customers are billed a fixed fee per barrel of liquids transported multiplied by the volume delivered. The fees charged under these arrangements are either contractual or regulated by governmental agencies, including the FERC. Revenue associated with these fee-based contracts and tariffs is recognized when volumes have been delivered. Revenue from our refined products storage facilities is based on the number of days a customer has volumes in storage multiplied by a contractual storage rate. Under these contracts, revenue is recognized ratably over the length of the storage period. Revenue from product terminaling activities is recorded in the period such services are provided. Customers are typically billed a fee per unit of volume loaded.

Revenue is also generated from the provision of inland and offshore marine transportation of refined products, crude oil, condensate, asphalt, heavy fuel oil, liquefied petroleum gas and other petroleum products via tow boats and tank barges. Under our marine services transportation contracts, revenue is recognized over the transit time of individual tows as determined on an individual contract basis, which is generally less than ten days in duration. Revenue from these contracts is typically based on set day rates or a set fee per cargo movement. Most of the marine services transportation contracts include escalation provisions to recover increased operating costs such as incremental increases in labor. The costs of fuel, substantially all of which is a pass through expense, and other specified operational fees and costs are directly reimbursed by the customer under most of the contracts.

The results of operations from the distribution of lubrication oils and specialty chemicals and the transportation of products by truck are dependent on the sales price or transportation fees that we charge our customers and the volume sold or transported. Likewise, revenue from the production and sale of octane additives and high purity isobutylene is dependent on the sales price and volume of such commodities sold to customers. Revenue is recognized for sales transactions when the product is delivered.

Note 5. 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 the expense we recognized in connection with equity-based awards for the periods presented:

	For Year Ended December 31,
	2011		2010		2009
Restricted common unit awards (1)	$	47.5	$	31.5	$	13.6
Unit option awards		3.1		3.4		2.0
Other (2)		0.3		35.5		9.4
Total compensation expense	$	50.9	$	70.4	$	25.0

(1) The increase in expense for restricted unit awards between periods is primarily due to a change in vesting provisions beginning with restricted common unit awards granted in 2010 (see below). (2) Primarily consists of unit appreciation rights (“UARs”), phantom units and similar awards. Also, the amounts presented for 2010 and 2009 include compensation expense for awards related to limited partnership interests in the Employee Partnerships, which were liquidated in August 2010.

The fair value of equity-classified awards (e.g., restricted common unit and unit option awards) is amortized to earnings over the requisite service or vesting period. Compensation expense for liability-classified awards (e.g., UARs and phantom units) is recognized over the requisite service or vesting period based on the fair value of the award remeasured at each reporting period. Liability-classified awards are settled in cash upon vesting.

At December 31, 2011, EPCO’s significant long-term incentive plans applicable to us were the Enterprise Products 1998 Long-Term Incentive Plan (“1998 Plan”) and the Amended and Restated 2008 Enterprise Products Long-Term Incentive Plan (“2008 Plan”). In addition, there were unvested awards outstanding under an inactive plan, the Enterprise Products 2006 TPP Long-Term Incentive Plan (“2006 Plan”).

The 1998 Plan provides for awards of our common units and other rights to our non-employee directors and to employees of EPCO and its affiliates providing services to us. Awards under the 1998 Plan may be granted in the form of unit options, restricted common units, phantom units and distribution equivalent rights (“DERs”). Up to 7,000,000 of our common units may be issued as awards under the 1998 Plan. After giving effect to awards granted under the plan through December 31, 2011, a total of 1,484,801 additional common units could be issued.

The 2008 Plan provides for awards of our common units and other rights to our non-employee directors and to consultants and employees of EPCO and its affiliates providing services to us. Awards under the 2008 Plan may be granted in the form of unit options, restricted common units, phantom units, UARs and DERs. Up to 10,000,000 of our common units may be issued as awards under the 2008 Plan. After giving effect to awards granted under the plan through December 31, 2011, a total of 4,760,524 additional common units could be issued.

The 2006 Plan provided for awards of our common units (formerly of TEPPCO units) and other rights to our non-employee directors and to employees of EPCO and its affiliates providing services to us. Awards under the 2006 Plan were granted in the form of unit options, restricted common units, phantom units, UARs and DERs. Effective upon the consummation of the TEPPCO Merger (see Note 1), we assumed the vested and unvested options, restricted common units and UARs outstanding on October 26,

2009 under the 2006 Plan and converted them into our options, restricted common units and UARs based on the TEPPCO Merger exchange ratio. The vesting terms of each award and other provisions of the plan remain unchanged.

In connection with the Duncan Merger, the 2010 Duncan Energy Partners L.P. Long-Term Incentive Plan (“2010 Plan”) was terminated. The 2010 Plan provided for awards to employees, directors or consultants providing services to Duncan Energy Partners. Awards under the 2010 Plan were granted in the form of restricted common units. There were no awards outstanding under the 2010 Plan at September 6, 2011 (i.e., immediately prior to the Duncan Merger). See Note 1 for information regarding the Duncan Merger.

Restricted Common Unit Awards

Restricted common unit awards allow recipients to acquire our common units (at no cost to the recipient apart from service or other conditions) once a defined vesting period expires, subject to customary forfeiture provisions. For awards granted prior to 2010, the restrictions on such awards generally lapse four years from the date of grant. Beginning in 2010, new restricted common unit awards generally vest at a rate of 25% per year beginning one year after the grant date. As used in the context of EPCO’s long-term incentive plans, the term “restricted common unit” represents a time-vested unit. Such awards are non-vested until the required service period expires. Restricted common units are included in the number of common units presented on our Consolidated Balance Sheets.

The fair value of a restricted common unit award is based on the market price per unit of the underlying security 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.

(1) Determined by dividing the aggregate grant date fair value of awards before an allowance for forfeitures by the number of awards issued. With respect to restricted common unit awards assumed in connection with the TEPPCO Merger, the weighted-average grant date fair value per unit was determined by dividing the aggregate grant date fair value of the assumed awards before an allowance for forfeitures by the number of awards assumed. (2) Aggregate grant date fair value of restricted common unit awards issued during 2009 was $25.5 million based on grant date market prices of our common units ranging from $20.08 to $28.73 per unit. An estimated annual forfeiture rate of 4.6% was applied to these awards. (3) Aggregate grant date fair value of restricted common unit awards issued during 2010 was $45.4 million based on grant date market prices of our common units ranging from $32.00 to $43.18 per unit. An estimated annual forfeiture rate of 4.6% was applied to these awards. (4) Aggregate grant date fair value of restricted common unit awards issued during 2011 was $61.8 million based on a grant date market price of our common units ranging from $40.54 to $44.67 per unit. An estimated annual forfeiture rate of 4.6% was applied to these awards. (5) Includes awards granted to the independent directors of the boards of directors of EPGP, DEP GP and Holdings GP as part of their annual compensation for 2010. A total of 6,960, 6,348 and 3,424 restricted common unit awards were issued in February 2010 to the independent directors of EPGP, DEP GP and Holdings GP, respectively, that immediately vested upon issuance. (6) Includes awards granted to the independent directors of the boards of directors of Enterprise GP and DEP GP as part of their annual compensation for 2011. A total of 10,230 and 3,666 restricted common unit awards were issued in February 2011 to the independent directors of Enterprise GP and DEP GP, respectively, that immediately vested upon issuance. (7) Aggregate grant date fair value of restricted common unit awards issued during 2010 denominated in Duncan Energy Partners’ common units was $0.2 million based on a grant date market price of Duncan Energy Partners’ common units of $25.26 per unit. (8) Aggregate grant date fair value of restricted common unit awards issued during 2011 denominated in Duncan Energy Partners’ common units was $0.1 million based on a grant date market price of Duncan Energy Partners’ common units of $32.56 per unit.

Typically, each recipient is also 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 by the respective issuer. Since these restricted common units are participating securities, such distributions are included in cash distributions paid to partners (post-Holdings Merger) and cash distributions paid to noncontrolling interests (pre-Holdings Merger) as presented on our Statements of Consolidated Cash Flows.

The following table presents supplemental information regarding our restricted common unit awards for the periods presented:

	For Year Ended December 31,
	2011		2010		2009
Cash distributions paid to restricted common unit holders	$	9.6	$	8.0	$	5.2
Total intrinsic value of our restricted common unit awards vesting during year	$	39.1	$	13.9	$	7.8

For the EPCO group of companies, the unrecognized compensation cost associated with restricted common unit awards was an aggregate $49.3 million at December 31, 2011, of which our allocated share of the cost is currently estimated to be $46.7 million. We expect to recognize our share of the unrecognized compensation cost for these awards over a weighted-average period of 1.8 years.

Unit Option Awards

EPCO’s long-term incentive plans provide for the issuance of non-qualified incentive options. These unit option awards are denominated in our common units. When issued, the exercise price of each unit option grant may be no less than the market price of our common units on the date of grant. In general, option grants have a vesting period of four years from the date of grant and expire at the end of the calendar year following the year of vesting (e.g., an option vesting on May 29, 2011 will expire on December 31, 2012). However, unit options only become exercisable at certain times (typically the months of February, May, August and November) during the calendar year following the year in which they vest.

The fair value of each unit option is estimated on the date of grant using a Black-Scholes option pricing model, which incorporates various assumptions including expected life of the option, risk-free interest rates, expected distribution yield of our common units, and expected price volatility of our common units. In general, our assumption of expected life of the options represents the period of time that the options are expected to be outstanding based on an analysis of our historical option activity. Our selection of risk-free interest rates is based on published yields for U.S. government securities with terms comparable to the expected life of the option. The expected distribution yield and unit price volatility assumptions are estimated based on several factors, which include an analysis of historical price volatility and distribution yield over a period of time equal to the expected life of the option. Compensation expense recorded in connection with unit options is based on the grant date fair value of such awards, net of an allowance for estimated forfeitures, over the requisite service or vesting period.

(1) Aggregate intrinsic value reflects fully vested unit options at the date indicated. (2) Aggregate grant date fair value of these unit options issued during 2009 was $8.1 million based on the following assumptions: (i) a weighted-average grant date market price of our common units of $23.46 per unit; (ii) weighted-average expected life of options of 4.8 years; (iii) weighted-average risk-free interest rate of 2.1%; (iv) weighted-average expected distribution yield on our common units of 9.4% and (v) weighted-average expected unit price volatility on our common units of 57.4%. An estimated annual forfeiture rate of 4.6% was applied to awards granted during 2009. (3) Aggregate grant date fair value of these unit options issued during 2010 was $2.3 million based on the following assumptions: (i) a weighted-average grant date market price of our common units of $32.26 per unit; (ii) weighted-average expected life of options of 4.9 years; (iii) weighted-average risk-free interest rate of 2.5%; (iv) weighted-average expected distribution yield on our common units of 6.9%; and (v) weighted-average expected unit price volatility on our common units of 23.3%. An estimated annual forfeiture rate of 4.6% was applied to awards granted during 2010. (4) At December 31, 2011 and 2010, we were committed to issue 3,753,420 of our common units if all outstanding unit options awarded were exercised. Option awards outstanding at December 31, 2011 include 712,280 awards that vested during 2011 and became exercisable beginning in February 2012. Of the remaining outstanding option awards at December 31, 2011, 736,000, 1,520,140 and 785,000 will vest in 2012, 2013, and 2014, respectively. These unit option awards become exercisable in the calendar year following the year in which they vest.

In order to fund its unit option-related obligations, EPCO may purchase common units at fair value either in the open market or directly from us. When employees exercise unit options, 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.

(1) Prior to the Holdings Merger, the non-employee directors of DEP GP, the general partner of Duncan Energy Partners, were granted 90,000 UARs denominated in Holdings units in connection with certain letter agreements. The compensation expense and associated liability for these UARs was recognized by Enterprise since it owned DEP GP. At the effective date of the Holdings Merger in November 2010, these UARs were settled and $2.5 million in cash was paid to award recipients. (2) At the effective date of the Holdings Merger, Enterprise assumed 90,000 UARs that had been issued by Holdings GP to its non-employee directors. Since these UARs were denominated in Holdings units, they converted into 135,000 Enterprise UARs based on the 1.5:1 merger exchange ratio.

At December 31, 2011, there were 107,328 UARs outstanding that had been granted under the 2006 Plan. These awards are subject to five-year cliff vesting requirements and are expected to settle in 2012. The grant date fair value with respect to these UARs is based on a unit price of $37.00 for our common units. If the employee resigns prior to vesting, the UARs are forfeited. Compensation expense associated with UARs during the years ended December 31, 2011 and 2010 was a benefit of $0.4 million and an expense of $3.1 million, respectively. Compensation expense associated with UARs was minimal during the year ended December 31, 2009. The accrued liability for UARs at December 31, 2011 and 2010 was $0.5 million and $1.0 million.

Employee Partnerships

EPCO granted its key employees who perform services on behalf of us, EPCO and other affiliated companies, limited partnership interests in the Employee Partnerships, which were privately held affiliates of EPCO. These partnerships were liquidated in August 2010. Prior to liquidation, the limited partnership interests entitled each holder to participate in the expected long-term appreciation in value of the equity securities owned by each Employee Partnership. Each Employee Partnership owned either Enterprise common units or Holdings’ units or a combination of both. Equity-based compensation expense for the years ended December 31, 2010 and 2009 includes $31.3 million and $9.2 million, respectively, of expense associated with these limited partnership interests.

We recognized $26.8 million of expense in connection with the liquidation of the Employee Partnerships, of which $21.7 million was attributed to noncontrolling interests. Of this expense amount, $18.9 million was non-cash.

The grant date fair value of each Employee Partnership was based on (i) the estimated value of the assets, as determined using a Black-Scholes option pricing model, forecast to be distributed to the Class B limited partners upon dissolution of the Employee Partnerships plus (ii) the estimated value, based on a discounted cash flow analysis using appropriate discount rates, of the quarterly cash distributions that the

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Class B limited partners were forecast to receive (if any) over the assumed life of the Employee Partnership.

On an unallocated basis to the EPCO family of companies, the aggregate grant date fair value of the Employee Partnerships was $51.3 million at the time of liquidation, of which $40.4 million was attributable to the estimated value of the assets forecast to be distributed to the Class B limited partners upon dissolution of the Employee Partnerships. The following table presents changes in the aggregate grant date fair value (on an unallocated basis) of the Employee Partnerships for the periods shown:

	For Year Ended December 31,
	2010			2009
Aggregate grant date fair values at beginning of period	$	79.3		$	64.6
Modifications (1)		--			19.5
Other, including forfeiture and regrant activity (2,3)		(28.0	)		(4.8	)
Liquidation of partnerships		(51.3	)		--
Aggregate grant date fair values at end of period	$	--		$	79.3

(1) In December 2009, the expected liquidation date for each Employee Partnership was extended to February 2016. These modifications were intended to align the interests of the Class B partners with the long-term interests of EPCO and other unitholders in the relevant underlying publicly traded partnerships. (2) Amount presented for 2009 primarily reflects adjustments due to the dissolution of TEPPCO Unit L.P. and TEPPCO Unit II L.P. (3) Amount presented for 2010 reflects the decrease in fair value attributable to changes in the service period from February 2016 to August 2010 (the liquidation date) for all of the Employee Partnerships. The reduction is attributable to the cash distributions that the Class B limited partners would not receive from each Employee Partnership as a result of the August 2010 liquidations.

As noted previously, we used a Black-Scholes option pricing model to estimate the grant date fair value of the assets forecast to be distributed to the Class B limited partners upon dissolution of the Employee Partnerships. The following table summarizes the assumptions we used in determining the Black-Scholes values for each Employee Partnership:

Employee Partnership	Expected Life of Award	Risk-Free Interest Rate	Expected Distribution Yield	Expected Unit Price Volatility
EPE Unit I	3 to 6 years	1.2% to 5.0%	3.0% to 6.7%	16.6% to 35.0%
EPE Unit II	4 to 6 years	1.6% to 4.4%	3.8% to 6.4%	18.7% to 31.7%
EPE Unit III	4 to 6 years	1.4% to 4.9%	4.0% to 6.4%	16.6% to 32.2%
Enterprise Unit	4 to 6 years	1.4% to 3.9%	4.5% to 8.4%	15.3% to 31.7%
EPCO Unit	4 to 6 years	1.6% to 2.4%	8.1% to 11.1%	27.0% to 50.0%

Note 6. Derivative Instruments, Hedging Activities and Fair Value Measurements

We are required to recognize derivative instruments at fair value as either assets or liabilities on our balance sheet unless such instruments meet certain normal purchase/normal sale criteria. While all derivatives are required to be reported at fair value on the balance sheet, changes in fair value of the derivative instruments are reported in different ways, depending on the nature and effectiveness of the

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

hedging activities to which they relate. After meeting specified conditions, a qualified derivative may be designated as a total or partial hedge of:

§	Changes in the fair value of a recognized asset or liability, or an unrecognized firm commitment – In a fair value hedge, gains and losses for both the derivative instrument and the hedged item are recognized in income during the period of change.

§	Variable cash flows of a forecasted transaction – In a cash flow hedge, the effective portion of the hedge is reported in other comprehensive income (loss) and is reclassified into earnings when the forecasted transaction affects earnings.

An effective hedge relationship is one in which the change in fair value of a derivative instrument can be expected to offset 80% to 125% of the changes in fair value of a hedged item at inception and throughout the life of the hedging relationship. The effective portion of a hedge relationship is the amount by which the derivative instrument exactly offsets the change in fair value of the hedged item during the reporting period. Conversely, ineffectiveness represents the change in the fair value of the derivative instrument that does not exactly offset the change in the fair value of the hedged item. Any ineffectiveness associated with a hedge relationship is recognized in earnings immediately. Ineffectiveness can be caused by, among other things, changes in the timing of forecasted transactions or a mismatch of terms between the derivative instrument and the hedged item.

A contract designated as a cash flow hedge of an anticipated transaction that is probable of not occurring is immediately recognized in earnings.

Certain of our derivative instruments do not qualify for hedge accounting treatment; therefore, they are accounted for using mark-to-market accounting.

Interest Rate Derivative Instruments

The following table summarizes our portfolio of interest rate swaps at December 31, 2011:

Hedged Transaction	Number and Type of Derivative(s) Outstanding	Notional Amount	Period of Hedge	Rate Swap	Accounting Treatment
Senior Notes C	1 fixed-to-floating swap	$100.0	1/04 to 2/13	6.4% to 2.3%	Fair value hedge
Senior Notes G	3 fixed-to-floating swaps	$300.0	10/04 to 10/14	5.6% to 1.5%	Fair value hedge
Senior Notes P	7 fixed-to-floating swaps	$400.0	6/09 to 8/12	4.6% to 2.7%	Fair value hedge
Senior Notes AA	10 fixed-to-floating swaps	$750.0	1/11 to 2/16	3.2% to 1.3%	Fair value hedge
Undesignated swaps	6 floating-to-fixed swaps	$600.0	5/10 to 7/14	0.4% to 2.0%	Mark-to-market

Interest expense for the years ended December 31, 2011, 2010 and 2009 reflects a benefit of $19.6 million, and expenses of $16.5 million and $16.2 million, respectively, attributable to interest rate swaps.

In February 2012, we settled 11 fixed-to-floating interest rate swaps having an aggregate notional amount of $800.0 million, resulting in gains totaling $41.7 million. These gains will be amortized to earnings (as a decrease in interest expense) using the effective interest method over the forecasted hedged period.

The following table summarizes our portfolio of forward starting swaps outstanding at December 31, 2011. Forward starting swaps hedge the expected underlying benchmark interest rates related to future issuances of debt.

Hedged Transaction	Number and Type of Derivative(s) Outstanding	Notional Amount	Expected Termination Date	Average Rate Locked	Accounting Treatment
Future debt offering	10 forward starting swaps (1)	$500.0	2/12	4.5%	Cash flow hedge

Future debt offering	16 forward starting swaps	$1,000.0	3/13	3.7%	Cash flow hedge
(1) These swaps were settled in February 2012 in connection with the issuance of Senior Notes EE (see below).

In connection with the issuance of Senior Notes during the year ended December 31, 2011 (see Note 12), we settled three forward starting swaps and two treasury locks having an aggregate notional amount of $1.47 billion, resulting in losses totaling $23.2 million. These losses will be amortized to earnings (as an increase in interest expense) using the effective interest method over the forecasted hedge period.

In connection with the issuance of Senior Notes during the year ended December 31, 2010, we settled a forward starting swap having a notional amount of $50.0 million, resulting in a gain of $1.3 million, which will be amortized to earnings (as a decrease in interest expense) using the effective interest method over the forecasted hedge period.

In connection with the issuance of Senior Notes EE in February 2012 (see Note 23), we settled ten forward starting swaps having an aggregate notional value of $500.0 million, resulting in losses totaling $115.3 million. These losses will be reflected in other comprehensive income for the first quarter of 2012 and amortized to earnings (as an increase in interest expense) using the effective interest method over the forecasted hedge period of 10 years.

through the use of forward physical sales contracts and commodity derivative instruments and (ii) the purchase of commodity derivative instruments having a notional amount based on the volume of natural gas expected to be consumed as PTR in the production of such equity NGL production.

§	The objective of our NGL, refined products and crude oil sales hedging program is to hedge the margins of anticipated future sales of inventory by locking in sales prices through the use of forward physical sales contracts and commodity derivative instruments.

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

The earnings volatility caused by fluctuations in non-cash, mark-to-market earnings cannot be predicted and the impact to earnings could be material.

Credit-Risk Related Contingent Features in Derivative Instruments

A limited number of our commodity derivative instruments include provisions related to credit ratings and/or adequate assurance clauses. A credit rating provision provides for a counterparty to demand immediate full or partial payment to cover a net liability position upon the loss of a stipulated credit rating. An adequate assurance clause provides for a counterparty to demand immediate full or partial payment to cover a net liability position should reasonable grounds for insecurity arise with respect to contractual performance by either party. At December 31, 2011 , we did not have any over-the-counter derivative instruments with an aggregate fair value in a net liability position. The maximum potential cash payment under the contracts containing a credit rating contingent feature is $1.1 million. The potential for derivatives with contingent features to enter a net liability position may change in the future as commodity positions and prices fluctuate.

(1) The other comprehensive loss recognized for interest rate derivatives during 2011 is primarily due to the impact of decreases in forward London Interbank Offered Rates (“LIBOR”) on our forward starting interest rate swap portfolio. The change in fair value of this portfolio during 2011 accounted for $315.5 million of the other comprehensive loss. Any gain or loss ultimately recognized upon settlement of these cash flow hedges would be amortized into earnings as a reduction or increase, respectively, in interest expense over the forecasted hedge period. In February 2012, we settled ten of these forward starting swaps having an aggregate notional amount of $500.0 million, resulting in losses totaling $115.3 million. (2) The increase in other comprehensive loss during 2011 is primarily due to the impact of rising prices on our crude oil, refined products and NGL derivative instruments designated as cash flow hedges of future physical sales transactions.

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. Recognized valuation techniques employ inputs such as product prices, 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 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 or disclosed 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.

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

The characteristics of fair value amounts classified within each level of the hierarchy are described as follows:

Level 1 fair values are based on quoted prices, which are available in active markets for identical assets or liabilities as of the measurement date. Active markets are defined as those in which transactions for identical assets or liabilities occur with sufficient frequency so as to provide pricing information on an ongoing basis (e.g., the New York Mercantile Exchange). Our Level 1 fair values consist of financial assets and liabilities such as exchange-traded commodity derivative instruments.

Level 2 fair values are based on pricing inputs other than quoted prices in active markets (as reflected in Level 1 fair values) and are either directly or indirectly observable as of the measurement date. Level 2 fair values include instruments that are valued using financial models or other appropriate valuation methodologies. Such financial models are primarily industry-standard models that consider various assumptions, including quoted forward prices for commodities, the time value of money, volatility factors, current market and contractual prices for the underlying instruments and other relevant economic measures. Substantially all of these assumptions (i) are observable in the marketplace throughout the full term of the instrument; (ii) can be derived from observable data; or (iii) are validated by inputs other than quoted prices (e.g., interest rate and yield curves at commonly quoted intervals). Our Level 2 fair values primarily consist of commodity derivative instruments such as forwards, swaps and other instruments transacted on an exchange or over-the-counter and interest rate derivative instruments. The fair values of these derivative instruments are based on observable price quotes for similar products and locations. The fair value of our interest rate derivatives are determined using financial models that incorporate the implied forward LIBOR yield curve for the same period as the future interest rate swap settlements.

Level 3 fair values are based on unobservable inputs. Unobservable inputs are used to measure fair value to the extent that observable inputs are not available, thereby allowing for situations in which there is little, if any, market activity for the asset or liability at the measurement date. Unobservable inputs reflect management’s ideas about the assumptions that market participants would use in pricing an asset or liability (including assumptions about risk). Unobservable inputs are based on the best information available to us in the circumstances, which might include our internally developed data. Level 3 inputs are typically used in connection with internally developed valuation methodologies where we make our best estimate of an instrument’s fair value. Our Level 3 fair values primarily consist of ethane, normal butane and natural gasoline-based contracts with terms greater than one year and certain options used to hedge natural gas storage inventory and transportation capacities. In addition, we often rely on price quotes from reputable

F-37

Table of Contents

ENTERPRISE PRODUCTS PARTNERS L.P.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

brokers who publish price quotes on certain products and compare these prices to other reputable brokers for the same products in the same markets whenever possible. These prices, when combined with data from our commodity derivative instruments, are used in our models to determine the fair value of such instruments.

Transfers within the fair value hierarchy routinely occur for certain term contracts as prices and other inputs used for the valuation of future delivery periods become more observable with the passage of time. Other transfers are made periodically in response to changing market conditions that affect liquidity, price observability and other inputs used in determining valuations. Based on an assessment completed during the first quarter of 2011, we transferred ethane, normal butane and natural gasoline-based contracts with terms ranging from two months to one year from Level 3 to Level 2. These transfers were made after a sustained increase in the observability of forward prices for these energy commodity products relative to the date range stated above as demonstrated by narrowing bid/offer spreads, higher transaction volumes and more activity and liquidity for these types of contracts. With the exception of the transfers noted above, no other significant transfers were made between fair value levels during the periods presented.

The following table sets forth a reconciliation of changes in the overall fair values of our Level 3 financial assets and liabilities for the periods presented:

(1) There were unrealized gains of $2.6 million and $10.3 million included in these amounts for the years ended December 31, 2011 and 2010, respectively. (2) Transfers out of Level 3 into Level 2 during 2011 were primarily due to the change in observability of forward NGL prices as described above.

Nonfinancial Assets and Liabilities

Certain nonfinancial assets and liabilities are measured at fair value on a nonrecurring basis (e.g., property, plant and equipment) and are subject to fair value adjustments under certain circumstances.

Using appropriate valuation techniques, we reduced the carrying value of certain assets recorded as property, plant and equipment to an estimated fair value of $0.4 million based on the present value of expected future cash flows (Level 3), resulting in nonrecurring fair value adjustments (i.e., non-cash asset impairment charges) totaling $16.7 million during the year ended December 31, 2011. These impairment charges recorded during 2011 resulted from the abandonment of certain pipeline laterals on our TPC Offshore gathering system and certain storage caverns. Also during 2011, we reduced the carrying value of certain spare parts inventories to their estimated fair value of $2.7 million using fair market value (Level 2), resulting in nonrecurring fair value adjustments of $11.1 million. These non-cash impairment charges were recorded to reflect obsolescence or the value of what we can expect to receive from anticipated sales.

During the year ended December 31, 2010, we reduced the carrying value of certain assets recorded as property, plant and equipment and other current assets to an estimated fair value of $0.7 million during the year ended December 31, 2010. This resulted in non-cash asset impairment charges of $8.4 million. These impairment charges resulted primarily from the anticipated abandonment of certain pipeline laterals on our TPC Offshore gathering system, the cancellation of a compressor station project on our Texas Intrastate System and the determination that three of our underground NGL storage caverns would not be returned to service due to integrity concerns. Our fair value estimates were based primarily on an evaluation of the future cash flows associated with each asset (Level 3).

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

During the year ended December 31, 2009, we reduced the carrying value of certain assets recorded as property, plant and equipment, intangible assets and other current assets to an estimated fair value of $31.4 million based on an evaluation of future cash flows (Level 3). These adjustments resulted in non-cash asset impairment charges totaling $32.2 million. In addition, we recorded a goodwill impairment charge of $1.3 million during 2009. Impairment charges recorded during 2009 resulted from reduced levels of throughput at certain river terminals, the indefinite suspension of certain river terminal expansion projects, and the determination that an underground natural gas storage cavern and certain marine transportation assets were obsolete. The affected river terminals were also subject to a throughput contract with a third party, which resulted in a $28.7 million charge recorded in 2009 for deficiency fees.

The non-cash impairment charges we recorded during the years ended December 31, 2011, 2010 and 2009 are a component of operating costs and expenses. The following table summarizes our non-cash impairment charges by segment during each of the last three years:

	For Year Ended December 31,
	2011		2010		2009
NGL Pipelines & Services	$	11.3	$	2.8	$	4.1
Onshore Natural Gas Pipelines & Services		10.4		5.2		4.3
Offshore Pipelines & Services		5.5		--		--
Petrochemical & Refined Products Services		0.6		0.4		25.1
Total non-cash impairment charges	$	27.8	$	8.4	$	33.5

Note 7. Inventories

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

	December 31,
	2011		2010
NGLs	$	563.6	$	548.3
Petrochemicals and refined products		443.4		399.7
Crude oil		39.2		121.1
Natural gas		65.5		64.7
Other		--		0.2
Total	$	1,111.7	$	1,134.0

In those instances where we take ownership of inventory volumes through percent-of-liquids contracts and similar arrangements (as opposed to actually purchasing volumes for cash from third parties), these volumes are valued at market-based prices during the month in which they are acquired.

Due to fluctuating commodity prices, we recognize lower of cost or market adjustments when the carrying value of our inventories exceeds their net realizable value. These non-cash charges are a component of cost of sales in the period they are recognized. To the extent our commodity hedging strategies address inventory-related price risks and are successful, these inventory valuation adjustments are mitigated or offset. See Note 6 for a description of our commodity hedging activities. The following table summarizes our cost of sales and lower of cost or market adjustments for the periods presented:

	For Year Ended December 31,
	2011		2010		2009
Cost of sales (1)	$	38,292.6	$	28,761.6	$	20,921.8
Lower of cost or market adjustments		9.5		7.9		6.3
(1) Cost of sales is a component of “Operating costs and expenses,” as presented on our Statements of Consolidated Operations. Year-to-year fluctuations in these amounts are primarily due to changes in energy commodity prices and sales volumes associated with our marketing activities.

(1) Plants and pipelines include processing plants; NGL, natural gas, crude oil and petrochemical and refined products pipelines; terminal loading and unloading facilities; office furniture and equipment; buildings; 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) Platforms and facilities include offshore platforms and related facilities and other associated assets located in the Gulf of Mexico. (4) Transportation equipment includes tractor-trailer tank trucks and other vehicles and similar assets used in our operations. (5) Marine vessels include tow boats, barges and related equipment used in our marine transportation business. (6) 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; office furniture and equipment, 3-20 years; buildings, 20-40 years; and laboratory and shop equipment, 5-35 years. (7) In general, the estimated useful lives of assets within this category are: underground storage facilities, 5-35 years; storage tanks, 10-40 years; and water wells, 5-35 years.

In October 2011, we announced the execution of definitive agreements to sell the equity interests of a wholly owned subsidiary, Crystal Holding L.L.C. (“Crystal”), which owns two underground salt dome natural gas storage facilities and associated pipelines located near Petal and Hattiesburg, Mississippi. The facilities have a combined 28.8 Bcf of total storage capacity (of which 18.6 Bcf is total working gas capacity) and are owned by Petal Gas Storage, L.L.C. (“Petal”) and Hattiesburg Gas Storage Company (“Hattiesburg”). We completed the sale of Crystal on December 1, 2011 and received $547.8 million in cash, net of working capital adjustments. We recorded a $129.1 million gain on the sale of Crystal. At December 1, 2011, the net carrying value of our investment in Crystal was approximately $411.9 million , of which $356.2 million was the total net carrying value of Crystal’s property, plant and equipment.

We determined that the financial results of Crystal did not meet the criteria to be classified as discontinued operations. Following the sale, we continue to have significant commercial contracts and operational arrangements at the Petal and Hattiesburg facilities, which are adjacent to and currently share operating assets with our retained Petal, Mississippi NGL storage facility.

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

	For Year Ended December 31,
	2011		2010		2009
Depreciation expense (1)	$	776.6	$	745.7	$	678.1
Capitalized interest (2)		106.7		47.2		53.1
(1) Depreciation expense is a component of “Costs and expenses” as presented in our Statements of Consolidated Operations. (2) Capitalized interest reduces interest expense during the period it is recorded and increases the carrying value of the associated asset, which will subsequently increase depreciation expense once the asset is placed in service. See Note 20 for information regarding cash payments for interest during the years ended December 31, 2011, 2010 and 2009.

Our consolidated results of operations for the years ended December 31, 2011, 2010 and 2009 included $19.7 million, $30.5 million and $33.4 million of depreciation, amortization and accretion expense related to the Crystal assets.

Asset Retirement Obligations

We record AROs related to legal requirements to perform retirement activities as specified in contractual arrangements and/or governmental regulations. In general, our contractual AROs primarily result from right-of-way agreements associated with our pipeline operations and leases of plant sites. In addition, we have recorded AROs based on government regulations triggered by the abandonment or retirement of (i) certain underground storage facilities and related above-ground brine storage pits, (ii) offshore Gulf of Mexico assets and (iii) certain marine vessels. Our AROs may also result from regulatory requirements associated with the renovation or demolition of certain assets containing hazardous substances such as asbestos. We fund our ARO obligations using cash flow from operations, borrowings under credit agreements, or a combination thereof.

The following table presents information regarding our AROs since December 31, 2009:

ARO liability balance, December 31, 2009	$	54.8
Liabilities incurred		0.1
Liabilities settled		(7.6	)
Revisions in estimated cash flows		45.6
Accretion expense		4.2
ARO liability balance, December 31, 2010		97.1
Liabilities incurred		0.7
Liabilities settled		(7.3	)
Revisions in estimated cash flows		15.0
Accretion expense		6.5
ARO liability balance, December 31, 2011	$	112.0

The increase in our ARO liability during 2010 and 2011 primarily reflects revised cost estimates and/or settlement date assumptions for pipeline and platform abandonment projects in the Gulf of Mexico and certain onshore natural gas gathering systems. Revised estimates of the cost to comply with regulatory abandonment obligations associated with above-ground brine storage pits also contributed to the increase in our ARO liability balance during 2010.

Property, plant and equipment at December 31, 2011 and 2010 includes $37.7 million and $34.1 million, respectively, of asset retirement costs capitalized as an increase in the associated long-lived asset. The following table presents our accretion expense forecasts for AROs for the periods presented:

2012				2013				2014				2015				2016

Other Investments

This segment reflects our noncontrolling ownership interest in Energy Transfer Equity, which was accounted for using the equity method as of December 31, 2011. In May 2007, Holdings paid $1.65 billion to acquire 38,976,090 limited partner common units of Energy Transfer Equity and approximately 34.9% of the membership interests of LE GP, which is the general partner of Energy Transfer Equity. In January 2009, Holdings acquired an additional 5.7% membership interest in LE GP for $0.8 million. In December 2010, we sold our entire membership interest in LE GP and recorded a nominal gain on the transaction.

Energy Transfer Equity is a publicly traded partnership, which currently owns the general partner of Energy Transfer Partners, L.P. (“ETP”) and approximately 50.2 million ETP limited partner units, as well as the general partner of Regency Energy Partners LP (“Regency”) and approximately 26.3 million Regency limited partner units. Energy Transfer Equity and its affiliates are part of the midstream energy industry.

At December 31, 2011, we owned 29,303,514 common units of Energy Transfer Equity. Equity investments are part of our business strategy; however, we may from time-to-time elect to divest all or a portion of our equity investments in order to redeploy capital. During 2011, we sold a total of 9,672,576 Energy Transfer Equity common units for net cash proceeds of $375.2 million and recorded aggregate gains of $27.2 million on the sales. Proceeds from these transactions were used for general company purposes, including funding capital expenditures.

(1) Holdings’ investment in Energy Transfer Equity exceeded its share of the historical cost of the underlying net assets of such investee by $1.66 billion in May 2007. At December 31, 2011, this basis differential decreased to $1.12 billion (after taking into account related amortization amounts and the sale of 9.67 million Energy Transfer Equity common units during 2011) and consisted of the following: $348.7 million attributed to fixed assets; $383.1 million attributed to the incentive distribution rights (an indefinite-life intangible asset) held by Energy Transfer Equity in the cash flows of ETP; $136.7 million attributed to amortizable intangible assets and $250.5 million attributed to equity method goodwill. These unamortized excess cost amounts are being amortized over their estimated economic lives of 20-27 years, as applicable.

We amortize such excess cost amounts as a reduction in equity earnings in a manner similar to depreciation. The following table presents our amortization of such excess cost amounts by business segment for the periods presented:

Aside from the State Line and Fairplay natural gas gathering systems acquisition in May 2010, on a pro forma consolidated basis, our revenues, costs and expenses, operating income, net income attributable to partners and earnings per unit amounts would not have differed materially from those we actually reported for 2010 and 2009 due to the immaterial nature of our business combination transactions for those respective periods.

2010 Transactions

State Line and Fairplay Natural Gas Gathering Systems . In May 2010, we acquired 100% ownership of the State Line and Fairplay natural gas gathering systems and related assets from M2 Midstream LLC for approximately $1.2 billion in cash. These systems are located in northwest Louisiana and East Texas and gather and treat natural gas produced from the Haynesville/Bossier Shales and the Cotton Valley and Taylor Sand formations. We used a portion of the net proceeds from our April 2010 equity offering, together with borrowings under EPO’s $1.75 Billion Multi-Year Revolving Credit Facility, to fund this acquisition.

On a combined basis, our revenues and net income from the State Line and Fairplay systems were $119.8 million and $14.4 million, respectively, for the eight months we owned these assets during 2010.

Pro Forma Financial Information . Since the effective date of the State Line and Fairplay acquisitions was May 1, 2010, our Statements of Consolidated Operations do not include earnings from these businesses prior to this date. The following table presents selected unaudited pro forma earnings information for the periods presented as if the acquisitions had been completed on January 1 of each year presented.

Cenac Acquisition . In November 2010, we acquired certain assets from Cenac Towing Co., L.L.C., Cenac Offshore, L.L.C., CTCO Marine Services, LLC, and CTCO Shipyard of Louisiana, LLC relating to their shipyard operations in Louisiana and certain membership interests in CTCO of Texas, L.L.C. and Channelview Fleeting Services, LLC relating to shipyard operations in Texas. Since entering into the marine transportation business in 2008, we paid the above entities for services to support our marine transportation business, including construction, repairs and maintenance, drydock and provisioning services. We expect these acquired assets will result in significant future cost savings for our marine fleet.

This transaction was valued at $141.9 million and the consideration consists of $42.2 million in cash and $99.7 million of our common units (represented by approximately 2.3 million common units). This business is part of our Petrochemical & Refined Products Services business segment.

Bigler Acquisition . In November 2010, we acquired a facility located on the Houston Ship Channel for $38.5 million in cash that produces high-purity isobutylene and provides terminal services for refined products and petrochemicals. This business is part of our Petrochemical & Refined Products Services business segment.

Other Transactions . In June 2010, we acquired a marine transportation business located in south Louisiana for $12.0 million in cash. This business is engaged in crude oil gathering and included three tug boats and five barges that are part of our Petrochemical & Refined Products Services business segment. In August 2010, we acquired a crude oil trucking business located in North Dakota for $4.0 million. This business is part of our Onshore Crude Oil Pipelines & Services business segment.

See Note 15 for information regarding a September 2010 drop down transaction whereby we acquired ownership interests in EPCO’s trucking business.

$	123.3			$	109.3			$	106.7			$	106.2			$	107.6

In general, our intangible assets fall within two categories – customer relationship and contract-based intangible assets. The values assigned to such intangible assets are amortized to earnings using either (i) a straight-line approach or (ii) other methods that closely resemble the pattern in which the economic benefits of associated resource bases are estimated to be consumed or otherwise used, as appropriate.

Customer relationship intangible assets . Customer relationship intangible assets represent the estimated economic value assigned to certain relationships acquired in connection with business combinations and asset purchases whereby (i) we acquired information about or access to customers and now have the ability to provide services to them and (ii) the customers now have the ability to make direct contact with us. Customer relationships may arise from contractual arrangements (such as service contracts) and through means other than contracts, such as through regular contact by sales or service representatives.

At December 31, 2011, the carrying value of our customer relationship intangible assets was $1.32 billion. The following information summarizes the significant components of this category of intangible assets:

§	State Line and Fairplay customer relationships – We acquired these customer relationships in connection with our acquisition of the State Line and Fairplay natural gas gathering systems in May 2010. The acquired customer relationships as of December 31, 2011 are presented in the following table:

	Gross Value		Accum. Amort.			Carrying Value
State Line natural gas gathering customer relationships (1)	$	675.0	$	(36.1	)	$	638.9
Fairplay natural gas gathering customer relationships (1)		116.6		(11.6	)		105.0
Fairplay natural gas processing customer relationships (2)		103.4		(10.3	)		93.1
Total acquired customer relationships	$	895.0	$	(58.0	)	$	837.0

(1) These natural gas gathering customer relationship intangible assets are a component of our Onshore Natural Gas Pipelines & Services business segment. (2) The Fairplay natural gas processing customer relationship intangible assets are a component of our NGL Pipelines & Services business segment.

In this context, a customer relationship is broadly defined as a relationship between the natural gas gathering system and the production fields from which it gathers natural gas. Natural gas gathering systems require a significant investment, both in terms of initial construction costs and ongoing maintenance. Investing the capital to construct a natural gas gathering system establishes access to producers in a particular field and represents a significant economic barrier effectively limiting competition (i.e., akin to a franchise). The low risk of competition ensures a long commercial relationship with existing customers as well as a high probability of commercial

F-50

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

relationships with new producers in the field. As such, the relationship with producers is generally limited by the quantity and production life of the underlying natural gas resource base.

The economic value we attribute to customer relationships acquired with the State Line and Fairplay systems was estimated using recognized business valuation techniques based on several key assumptions, which include assumptions regarding the renewal of existing contracts and natural gas resource bases. In general, natural gas is gathered on the State Line and Fairplay systems under long-term contracts, which include acreage dedications of approximately 110,000 acres and 100,000 acres, respectively, as well as volumetric commitments from certain natural gas producers on both systems. In addition, certain contracts related to the Fairplay system include natural gas processing services. Based on our experience as a provider of natural gas gathering and processing services, we anticipate the acquired customer relationships to extend well beyond the discrete term of existing contracts.

Customer relationship intangibles related to the State Line system have an estimated economic useful life of 27 years. The natural gas gathering and processing customer relationships associated with the Fairplay system have an estimated economic useful life of 23 years. Amortization expense is recorded using the units-of-production method based on gathering volumes. This method of amortization allows for expense to be recorded in a manner that closely resembles the pattern in which we benefit from natural gas gathering and processing services provided to customers. See Note 10 for additional information regarding this business combination.

San Juan Gathering System customer relationships – We acquired these customer relationships in connection with the GulfTerra Merger, which was completed in September 2004. At December 31, 2011, the carrying value of this group of intangible assets was $188.1 million. These intangible assets are being amortized to earnings over their estimated economic life of 35 years through 2039. Amortization expense is recorded using a method that closely resembles the pattern in which the economic benefits of the underlying natural gas resource bases are expected to be consumed or otherwise used.

Offshore Pipeline & Platform customer relationships – We acquired these customer relationships in connection with the GulfTerra Merger. At December 31, 2011, the carrying value of this group of intangible assets was $76.6 million. These intangible assets are being amortized to earnings over their estimated economic lives, which range from 18 to 33 years (i.e., through 2022 to 2037). Amortization expense is recorded using a method that closely resembles the pattern in which the economic benefits of the underlying crude oil and natural gas resource bases are expected to be consumed or otherwise used.

Encinal natural gas processing customer relationship – We acquired this customer relationship in connection with our acquisition of certain South Texas midstream energy assets in 2006. At December 31, 2011, the carrying value of this intangible asset was $71.8 million. This intangible asset is being amortized to earnings over its estimated economic life of 20 years through 2026. Amortization expense is recorded using a method that closely resembles the pattern in which the economic benefit of the underlying natural gas resource bases are expected to be consumed or otherwise used.

Contract-based intangible assets . Contract-based intangible assets represent specific commercial rights we acquired in connection with business combinations or asset purchases. At December 31, 2011, the carrying value of our contract-based intangible assets was $331.6 million. The following information summarizes the significant components of this category of intangible assets:

Enterprise Jonah Gas Gathering Company LLC (“Jonah”) natural gas gathering agreements – These intangible assets represent the value attributed to certain of Jonah’s natural gas gathering contracts that were originally acquired by TEPPCO in 2001. At December 31, 2011, the carrying value of this group of intangible assets was $104.0 million. These intangible assets are being

amortized to earnings using a units-of-production method based on gathering volumes on the Jonah system, which is estimated to extend through 2041.

Shell Processing Agreement – This margin-band/keepwhole processing agreement grants us the right to process Shell Oil Company’s (or its assignee’s) current and future natural gas production within the state and federal waters of the Gulf of Mexico. We acquired the Shell Processing Agreement in connection with our 1999 purchase of certain of Shell’s midstream energy assets located along the U.S. Gulf Coast. At December 31, 2011, the carrying value of this intangible asset was $83.8 million. This intangible asset is being amortized to earnings on a straight-line basis over its estimated economic life of 20 years through 2019.

San Juan basin natural gas gathering agreements – These intangible assets represent the value attributed to certain natural gas gathering contracts with producers in the San Juan basin that were originally acquired by TEPPCO in 2002. At December 31, 2011, the carrying value of these intangible assets was $69.3 million. These intangible assets are being amortized to earnings using a units-of-production method based on gathering volumes on the San Juan Gathering System, which is estimated to extend through 2021.

Goodwill impairment testing involves determining the fair value of the associated reporting unit. These fair value amounts are based on assumptions regarding the future economic prospects of the businesses that make up the reporting unit. Such assumptions include (i) discrete financial forecasts for the businesses contained within the reporting unit, which rely on management’s estimates of operating margins, throughput volumes and similar factors; (ii) long-term growth rates for cash flows beyond the discrete forecast period; and (iii) appropriate discount rates. Based on our most recent goodwill impairment tests, each reporting unit’s fair value was substantially in excess of its carrying value (i.e., by at least 10%).

Letters of Credit

At December 31, 2011, EPO had $77.5 million in letters of credit outstanding related to its commodity derivative instruments. These letters of credit do not reduce the amount available for borrowing under EPO’s $3.5 Billion Multi-Year Revolving Credit Facility.

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 repayment of that obligation.

EPO’s Debt Obligations

$3.5 Billion Multi-Year Revolving Credit Facility . In September 2011, EPO entered into a new $3.5 billion variable-rate multi-year revolving credit facility that matures in September 2016. Initial borrowings under this credit facility were used to refinance and terminate EPO’s prior $1.75 billion multi-year revolving credit facility. Future borrowings under the new credit facility may be used for working capital, capital expenditures, acquisitions and general company purposes.

As defined by the credit agreement, variable interest rates charged under this facility bear interest at LIBOR plus an applicable margin. In addition, EPO is required to pay a quarterly facility fee on each lender’s commitment irrespective of commitment usage. This revolving credit facility allows us to request up to two one-year extensions of the maturity date, subject to lender approval. The total amount of the bank commitments may be increased, without the consent of the lenders, by an amount not exceeding $500 million by adding one or more lenders to the facility and/or requesting that the commitments of existing lenders be increased.

The revolving credit facility contains certain financial and other customary affirmative and negative covenants. The credit agreement also restricts EPO’s ability to pay cash distributions to Enterprise Products Partners L.P. if a default or an event of default (as defined in the credit agreement) has occurred and is continuing at the time such distribution is scheduled to be paid. EPO’s borrowings under this agreement are unsecured general obligations that are guaranteed by Enterprise Products Partners L.P. and are non-recourse to Enterprise GP.

Petal GO Zone Bonds and MBFC Loan . As a condition to the sale of our equity interests in Crystal to Boardwalk, the Petal GO Zone bonds and MBFC Loan were repaid in December 2011. See Note 8 for additional information regarding this transaction.

Senior Notes . EPO’s senior fixed-rate notes are unsecured obligations of EPO and rank equal with its existing and future unsecured and unsubordinated indebtedness. They are senior to any existing and future subordinated indebtedness of EPO. EPO’s senior notes are subject to make-whole redemption rights and were issued under indentures containing certain covenants, which generally restrict its ability, with certain exceptions, to incur debt secured by liens and engage in sale and leaseback transactions.

In August 2011, EPO issued $650.0 million in principal amount of 10-year unsecured Senior Notes CC and $600.0 million in principal amount of 30-year unsecured Senior Notes DD. Senior Notes CC were issued at 99.790% of their principal amount, have a fixed interest rate of 4.05% and mature on February 15, 2022. Senior Notes DD were issued at 99.887% of their principal amount, have a fixed interest rate of 5.70% and mature on February 15, 2042. Net proceeds from the issuance of Senior Notes CC and DD were used (i) to temporarily reduce borrowings outstanding under EPO’s $1.75 Billion Multi-Year Revolving Credit Facility and (ii) for general company purposes.

In January 2011, EPO issued $750.0 million in principal amount of 5-year unsecured Senior Notes AA and $750.0 million in principal amount of 30-year unsecured Senior Notes BB. Senior Notes AA were

issued at 99.901% of their principal amount, have a fixed interest rate of 3.20% and mature on February 1, 2016. Senior Notes BB were issued at 99.317% of their principal amount, have a fixed interest rate of 5.95% and mature on February 1, 2041. Net proceeds from the issuance of Senior Notes AA and BB were used (i) to repay $450.0 million in aggregate principal amount of Senior Notes B that matured in February 2011, (ii) to temporarily reduce borrowings outstanding under EPO’s $1.75 Billion Multi-Year Revolving Credit Facility and (iii) for general company purposes.

In February 2012, EPO issued $750.0 million in principal amount of 30-year unsecured Senior Notes EE. See Note 23 for information regarding this subsequent event.

Junior Subordinated Notes. EPO’s payment obligations under its junior notes are subordinated to all of its current and future senior indebtedness (as defined in the related indenture agreement). We have guaranteed repayment of amounts due under these notes through an unsecured and subordinated guarantee. The indenture agreement governing these notes allows EPO to defer interest payments on one or more occasions for up to ten consecutive years subject to certain conditions. During any period in which interest payments are deferred and subject to certain exceptions, neither we nor EPO can declare or make any distributions to any of our respective equity securities or make any payments on indebtedness or other obligations that rank equal with or are subordinate to our junior notes. Each series of our subordinated junior notes are ranked equally with each other. Generally, each series of junior subordinated notes are not redeemable by EPO without payment of a make-whole premium while the notes bear interest at a fixed annual rate.

In connection with the issuance of each series of junior subordinated notes, EPO entered into separate Replacement Capital Covenants in favor of covered debt holders (as defined in the underlying documents) pursuant to which EPO agreed for the benefit of such debt holders that it would not redeem or repurchase such junior notes unless such redemption or repurchase is made using proceeds from the issuance of certain securities.

The following table summarizes the interest rate terms of our junior subordinated notes:

Series	Fixed Annual Interest Rate	Variable Annual Interest Rate Thereafter
Junior Subordinated Notes A	8.375% through August 2016 (1)	3-month LIBOR rate + 3.708% (4)
Junior Subordinated Notes B	7.034% through January 2018 (2)	Greater of: (i) 3-month LIBOR rate + 2.68% or (ii) 7.034% (5)
Junior Subordinated Notes C	7.00% through June 2017 (3)	3-month LIBOR rate + 2.778% (6)
(1) Interest is payable semi-annually in arrears in February and August of each year, which commenced in February 2007. (2) Interest is payable semi-annually in arrears in January and July of each year, which commenced in January 2008. (3) Interest is payable semi-annually in arrears in June and December of each year, which commenced in December 2009. (4) Interest is payable quarterly in arrears in February, May, August and November of each year commencing in November 2016. (5) Interest is payable quarterly in arrears in January, April, July and October of each year commencing in April 2018. (6) Interest is payable quarterly in arrears in March, June, September and December of each year commencing in June 2017.

TEPPCO’s Debt Obligations

TEPPCO Senior Notes . On October 27, 2009, $1.66 billion of the TEPPCO Senior Notes were exchanged for an equal amount of new EPO Senior Notes. In addition to the debt exchange, substantially all of the restrictive covenants and reporting requirements associated with the remaining TEPPCO Senior Notes were eliminated through amendments that became effective on October 26, 2009.

TEPPCO Junior Subordinated Notes . On October 27, 2009, $285.8 million of the TEPPCO Junior Subordinated Notes were exchanged for an equal amount of new EPO Junior Subordinated Notes. In addition to the debt exchange, substantially all of the restrictive covenants and reporting requirements associated with the remaining TEPPCO Junior Subordinated Notes were eliminated through amendments that became effective on October 26, 2009.

The terms and provisions of the TEPPCO’s Junior Subordinated Notes are similar to each series of EPO’s Junior Subordinated Notes. For example, they: (i) are general unsecured subordinated obligations,

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(ii) allow interest payments to be deferred for multiple periods of up to ten consecutive years and (iii) are subordinated in right of payment to all existing and future senior indebtedness. The maturity date, the interest rate and the interest payment due dates are the identical to EPO’s Junior Subordinated Notes C as discussed above.

In connection with the issuance of the TEPPCO Junior Subordinated Notes, TEPPCO, and TE Products Pipeline Company, LLC, TCTM, L.P., TEPPCO Midstream Companies, LLC and Val Verde Gas Gathering Company, L.P. entered into a Replacement Capital Covenant in favor of the covered debt holders (as defined in the underlying documents) pursuant to which TEPPCO agreed for the benefit of such debt holders that it would not redeem or repurchase such junior notes unless such redemption or repurchase is made using proceeds from the issuance of certain securities. The Replacement Capital Covenant is not a term of the governing indenture or the junior subordinated notes.

Duncan Energy Partners’ Debt Obligations

Prior to the Duncan Merger, we consolidated the debt of Duncan Energy Partners with that of our own; however, we did not have the obligation to make interest payments or debt payments with respect to the debt of Duncan Energy Partners. In September 2011, in connection with the Duncan Merger, all of Duncan Energy Partners’ outstanding debt obligations were repaid and terminated.

Covenants

We were in compliance with the financial covenants of our consolidated debt agreements at December 31, 2011.

Note 13 . Equity and Distributions

Partners Equity

Pre-Holdings Merger . As discussed in Note 1, the historical comparative financial statements presented herein are the financial statements of Holdings for periods prior to the effective date of the Holdings Merger. The following table summarizes changes in the number of Holdings’ limited partner units outstanding during the periods presented. Changes in Holdings’ limited partners’ equity for these periods are presented on our Statements of Consolidated Equity.

			Class C
	Units		Units
Balance, December 31, 2008		123,191,640		16,000,000
Conversion of Class C units to units		16,000,000		(16,000,000	)
Balance, December 31, 2009		139,191,640		--
Restricted common units granted and immediately vested		3,424		--
Balance, November 21, 2010		139,195,064		--

Holdings’ units represented limited partner interests, which gave the holders thereof the right to participate in cash distributions and to exercise the other rights or privileges available to them under Holdings’ partnership agreement (the “Holdings Partnership Agreement”). In accordance with Holdings Partnership Agreement, capital accounts were maintained for Holdings’ general partner and limited partners. Earnings and cash distributions were allocated to holders of Holdings units in accordance with their respective percentage interests.

In May 2007, Holdings issued 16,000,000 Class C units to private company affiliates of EPCO in connection with their contribution of 4,400,000 common units representing limited partner interests of TEPPCO and 100% of the general partner interest of TEPPCO GP. In February 2009, all of the Holdings Class C units were converted to Holdings units on a one-to-one basis. For financial accounting purposes, the Class C units were not allocated any portion of net income until their conversion into Holdings units (the Class C units were non-participating in current and undistributed earnings prior to conversion). The Holdings units into which the Class C units converted were eligible to receive cash distributions beginning with the distribution paid in May 2009.

Post-Holdings Merger . On November 22, 2010, the 139,195,064 Holdings units outstanding at the effective date of the Holdings Merger were converted into Enterprise common units at a ratio of 1.5 Enterprise common units to each Holdings unit and, as a result, Holdings’ unitholders received 208,813,454 Enterprise common units (net of fractional Enterprise common units that were cashed out).

In addition, the historical noncontrolling interests of Holdings related to limited partner interests in Enterprise that were owned by third parties and related parties other than Holdings was reclassified to limited partners’ equity at the effective date of the Holdings Merger. See “Noncontrolling Interests” below for information regarding our noncontrolling interest holders. Following the Holdings Merger, our partners’ equity reflects the various classes of limited partner interests of Enterprise (e.g., common units (including restricted common units) and Class B units).

Post-Duncan Merger . On September 7, 2011, the 24,036,950 Duncan Energy Partners common units outstanding, other than those beneficially owned by EPO, at the effective date of the Duncan Merger were converted into Enterprise common units at a ratio of 1.01 Enterprise common units to each Duncan common unit and, as a result, Duncan Energy Partners’ unitholders received 24,277,310 Enterprise common units (net of fractional Enterprise common units that were cashed out) as consideration in the Duncan Merger. No Enterprise common units were issued to Enterprise or its subsidiaries as merger consideration.

Our common units represent limited partner interests, which give the holders thereof the right to participate in distributions and to exercise the other rights or privileges available to them under our Sixth Amended and Restated Agreement of Limited Partnership (as amended from time to time, the “Partnership Agreement”). We are managed by our general partner, Enterprise GP.

In accordance with our Partnership Agreement, capital accounts are maintained for our general partner and limited partners. The capital account provisions of our Partnership Agreement incorporate principles established for U.S. Federal income tax purposes and are not comparable to the GAAP-based equity amounts presented in our consolidated financial statements. Earnings and cash distributions are allocated to holders of our common units in accordance with their respective percentage interests.

We have filed registration statements with the SEC authorizing the issuance of up to an aggregate of 70,000,000 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 common units they own by reinvesting the quarterly cash distributions they would otherwise receive into the purchase of additional common units. After taking into account the number of common units issued under this registration statement through December 31, 2011, Enterprise may issue an additional 26,173,283 common units under its DRIP. A total of 2,241,589

F-59

Table of Contents

ENTERPRISE PRODUCTS PARTNERS L.P.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

common units were issued during 2011 under our DRIP, which generated net cash proceeds of $90.4 million.

In May 2011, Enterprise’s original employee unit purchase plan (“EUPP”) reached the maximum 1,200,000 common units permitted under the plan and was terminated. In September 2011, in connection with the Duncan Merger, the Duncan Energy Partners EUPP was assumed by Enterprise and converted into a new Enterprise EUPP. Enterprise filed a registration statement with the SEC authorizing the issuance of 440,879 common units under the assumed plan. During 2011, Enterprise issued 96,315 common units in total under its EUPP plans, which generated net cash proceeds of $4.0 million.

Amounts received under the DRIP and EUPP prior to the Holdings Merger are a component of noncontrolling interests on our consolidated financial statements.

In August 2007, we filed a universal shelf registration statement (the “2007 Shelf”) with the SEC that allowed us to issue an unlimited amount of debt and equity securities. We issued 43,652,500 common units in underwritten equity offerings under this registration statement generating $1.27 billion of net cash proceeds and $5.2 billion of senior notes. Net cash proceeds from equity offerings under the 2007 Shelf are a component of noncontrolling interests.

In July 2010, we filed a new universal shelf registration statement (the “2010 Shelf”) with the SEC that replaced the 2007 Shelf, which was set to expire in August 2010. Like the 2007 Shelf, the 2010 Shelf allows us to issue an unlimited amount of debt and equity securities. In December 2010, we utilized the 2010 Shelf to issue 13,225,000 common units (including an over-allotment of 1,725,000 common units) to the public at an offering price of $41.25 per unit generating total net cash proceeds of $528.5 million.

We utilized the 2010 Shelf to issue $2.75 billion of unsecured senior notes during 2011 (see Note 12 for information regarding these debt issuances). In December 2011, we utilized the 2010 Shelf to issue 10,350,000 common units (including an over-allotment of 1,350,000 common units) to the public at an offering price of $44.68 per unit, which generated total net cash proceeds of approximately $448.5 million.

Net cash proceeds received from these offerings were used to temporarily reduce borrowings outstanding under EPO’s revolving credit facilities and for general company purposes.

Class B Units . In October 2009, in connection with the TEPPCO Merger (see Note 1), a privately held affiliate of EPCO exchanged a portion of its TEPPCO units, based on the 1.24 exchange ratio, for 4,520,431 of our Class B units in lieu of common units. The Class B units are not entitled to receive regular quarterly cash distributions for the first sixteen quarters following the closing date of the TEPPCO Merger in October 2009. The Class B units automatically convert into the same number of common units on the date immediately following the payment date for the sixteenth regular quarterly distribution following the closing date of the merger. The Class B units are entitled to vote together with the common units as a single class on partnership matters and, except for the payment of distributions, have the same rights and privileges as our common units.

Treasury Units . In 2000, we and a consolidated trust (the “1999 Trust”) were authorized to repurchase up to 2,000,000 publicly-held common units under an announced buy-back program. The repurchases would be made during periods of temporary market weakness at price levels that would be accretive to our remaining unitholders. After deducting for repurchases under the program in prior periods, we and the 1999 Trust could repurchase up to 618,400 common units at December 31, 2011.

During the year ended December 31, 2011, 936,608 restricted common unit and similar unit awards vested and converted to common units. Of this amount, 255,276 were sold back to us by employees

to cover related withholding tax requirements. We cancelled such treasury units immediately upon acquisition.

Accumulated Other Comprehensive Income (Loss)

Our accumulated other comprehensive income (loss) amounts primarily include the effective portion of the gain or loss on derivative instruments designated and qualified as cash flow hedges. Amounts accumulated in other comprehensive income (loss) related to cash flow hedges are reclassified into earnings in the same period(s) in which the underlying hedged forecasted transactions affect earnings. If it becomes probable that a forecasted transaction will not occur, the related net gain or loss in accumulated other comprehensive income (loss) must be immediately reclassified into earnings.

The following table presents the components of accumulated other comprehensive income (loss) as reported on our Consolidated Balance Sheets at the dates indicated:

Noncontrolling Interests

For periods prior to the TEPPCO Merger and Holdings Merger, the portion of the income of TEPPCO and Enterprise attributable to their respective limited partner interests that were owned by third parties and related parties other than Holdings (collectively referred to as the former owners of TEPPCO and Holdings, respectively) is included in net income attributable to noncontrolling interests as reflected on our Statements of Consolidated Operations. Prior to the completion of the Duncan Merger, effective September 6, 2011, we accounted for the former owners’ interest in Duncan Energy Partners as noncontrolling interest. Under this method of presentation, all pre-Duncan Merger revenues and expenses of Duncan Energy Partners are included in net income, and the former owners’ share of the income of Duncan Energy Partners is a component of net income attributable to noncontrolling interests as reflected on our Statements of Consolidated Operations.

Additionally, cash distributions paid to and cash contributions received from the former owners of TEPPCO, Holdings and Duncan Energy Partners are reflected as a component of cash distributions paid to and cash contributions received from noncontrolling interests.

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 the preparation of our consolidated financial statements. Gross operating margin is exclusive of other income and expense transactions, provision for 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 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. Our largest non-affiliated customer for 2011, 2010 and 2009 was Shell Oil Company and its affiliates, which accounted for 10.6%, 9.4% and 9.8% of our consolidated revenues, respectively.

We include equity in income of unconsolidated affiliates in our measurement of segment gross operating margin and operating income. Our equity investments with industry partners are a vital component of our business strategy. They are a means by which we conduct our operations to align our interests with those of our customers and/or suppliers. This method of operation enables us to achieve favorable economies of scale relative to the level of investment and business risk assumed versus what we could accomplish on a standalone basis. Many of these businesses perform supporting or complementary roles to our other business operations.

Our integrated midstream energy asset system (including the midstream energy assets of our equity method investees) provides services to producers and consumers of natural gas, NGLs, crude oil, refined products and certain petrochemicals. In general, hydrocarbons enter our asset system in a number of ways, such as an offshore natural gas or crude oil pipeline, an offshore platform, a natural gas processing plant, an onshore natural gas gathering pipeline, an onshore crude oil pipeline or terminal, an NGL fractionator, an NGL storage facility or an NGL transportation or distribution pipeline. Many of our equity investees are included within our integrated midstream asset system. For example, we have ownership interests in several offshore Gulf of Mexico natural gas, refined products and crude oil pipelines. Other examples include our use of the Promix NGL fractionator to process mixed NGLs extracted by our gas plants and our use of the Centennial pipeline to loop the Products Pipeline System. Given the integral nature of our equity method investees to our operations, we believe the presentation of equity earnings from such investees as a component of gross operating margin and operating income is meaningful and appropriate.

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 they 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.

Total consolidated costs and expenses	$	41,500.3		$	31,654.1		$	23,748.6

Changes in our revenues and operating costs and expenses year-to-year are explained in part by changes in energy commodity prices. In general, higher energy commodity prices result in an increase in our revenues attributable to the sale of NGLs, natural gas, crude oil, petrochemicals and refined products; however, these higher commodity prices also increase the associated cost of sales as purchase costs rise.

We have an extensive and ongoing relationship with EPCO and its affiliates, which include the following significant entities that are not a part of our consolidated group of companies:

§	EPCO and its privately held affiliates; and

§	Enterprise GP, our sole general partner.

EPCO is a privately held company controlled collectively by the EPCO Trustees. At December 31, 2011, EPCO and its affiliates (including Dan Duncan LLC and two Duncan family trusts, the beneficiaries of which include the estate of Mr. Duncan) beneficially owned the following limited partner interests in us:

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Dan Duncan LLC owns 100% of our general partner, Enterprise GP.

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 separate from those of EPCO and its other affiliates. EPCO and its privately held affiliates depend on the cash distributions they receive from us (including Holdings prior to the Holdings Merger) and other investments to fund their other operations and to meet their debt obligations. The following table presents cash distributions received by EPCO and its privately held affiliates from us and Holdings for the periods presented:

	For Year Ended December 31,
	2011		2010		2009
Enterprise	$	701.5	$	344.1	$	314.5
Holdings		--		237.4		205.2
Total distributions	$	701.5	$	581.5	$	519.7

We lease office space in various buildings from affiliates of EPCO. The rental rates in these lease agreements approximate market rates.

EPCO ASA . 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. We and our general partner are parties to the ASA. The significant terms of the ASA are as follows:

EPCO will provide selling, general and administrative services and management and operating services as may be necessary to manage and operate our businesses, properties and assets (all in accordance with prudent industry practices). EPCO will employ or otherwise retain the services of such personnel.

We are required to reimburse EPCO for its services in an amount equal to the sum of all costs and expenses incurred by EPCO which are directly or indirectly related to our business or activities (including expenses reasonably allocated to us by EPCO). In addition, we have agreed to pay all sales, use, excise, value added or similar taxes, if any, that may be applicable from time to time with respect to the services provided to us by EPCO.

§	EPCO will allow us to participate as a named insured in its overall insurance program, with the associated premiums and other costs being allocated to us. See Note 19 for additional information regarding our insurance programs.

Under the ASA, EPCO subleased to us (for $1 per year) certain equipment it held pursuant to operating leases. EPCO was liable for the cash payments associated with these lease agreements. In June 2011, we paid $5.4 million to purchase the assets from the lessor and the lease agreements were terminated. While these lease agreements were in effect, we recorded the full value of the lease payments made by EPCO on our behalf as a non-cash related party operating expense, with the offset to equity accounted for as a general contribution to our partnership.

Our operating costs and expenses include amounts paid to EPCO for the costs it incurs to operate our facilities, including the compensation of its employees. We reimburse EPCO for actual direct and indirect expenses it incurs related to the operation of our assets. Likewise, our general and administrative costs include amounts paid to EPCO for administrative services, including the compensation of its employees. In general, our reimbursement to EPCO for administrative services is either (i) on an actual

F-69

ENTERPRISE PRODUCTS PARTNERS L.P.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

basis for direct expenses it may incur on our behalf (e.g., the purchase of office supplies) or (ii) based on an allocation of such charges between the various parties to the ASA based on the estimated use of such services by each party (e.g., the allocation of legal or accounting salaries based on estimates of time spent on each entity’s business and affairs). The following table presents a breakout of costs and expenses related to the ASA and other EPCO transactions for the periods presented:

	For Year Ended December 31,
	2011		2010		2009
Operating costs and expenses	$	611.6	$	588.5	$	495.3
General and administrative expenses		111.1		124.0		97.2
Total costs and expenses	$	722.7	$	712.5	$	592.5

Since the vast majority of such expenses are charged to us on an actual basis (i.e., no mark-up or subsidy is charged or received by EPCO), we believe that such expenses are representative of what the amounts would have been on a standalone basis. With respect to allocated costs, we believe that the proportional direct allocation method employed by EPCO is reasonable and reflective of the estimated level of costs we would have incurred on a standalone basis.

Acquisition of EPCO’s Trucking Business . Historically, EPCO has provided us with tank truck services for the transportation of NGLs and other products. In September 2010, we acquired EPCO’s ownership interests in its trucking business, or “ETC,” in exchange for 523,306 of our common units. Since we and EPCO are under common control, we recorded the net assets of ETC based on EPCO’s historical basis of $37.8 million. The equity consideration we issued was based on the average closing price of our common units over a 20-day period ending September 28, 2010.

Relationships with Unconsolidated Affiliates

Many of our unconsolidated affiliates perform supporting or complementary roles to our other business operations. The following information summarizes significant related party transactions with our current unconsolidated affiliates:

§	We sell natural gas to Evangeline, which, in turn, uses the natural gas to satisfy supply commitments it has with a major Louisiana utility. Revenues from Evangeline were $166.1 million, $174.5 million and $155.5 million for the years ended December 31, 2011, 2010 and 2009, respectively.

We pay Promix for the transportation, storage and fractionation of NGLs. In addition, we sell natural gas to Promix for its plant fuel requirements. Revenues from Promix were $18.3 million, $13.1 million and $11.0 million for the years ended December 31, 2011, 2010 and 2009, respectively. Expenses with Promix were $44.9 million, $35.6 million and $26.0 million for the years ended December 31, 2011, 2010 and 2009, respectively.

§	For the years ended December 31, 2011, 2010 and 2009, we paid $2.8 million, $8.9 million and $6.7 million, respectively, to Centennial for other pipeline transportation services.

§	For the years ended December 31, 2011, 2010 and 2009, we paid Seaway $1.4 million, $4.5 million and $3.4 million, respectively, for pipeline transportation and tank rentals in connection with our crude oil marketing activities.

§	For the year ended December 31, 2011, 2010 and 2009, we paid White River Hub $6.7 million, $6.0 million and $6.5 million, respectively, primarily for firm capacity reservation fees.

§	We perform management services for certain of our unconsolidated affiliates. We charged such affiliates $13.0 million, $11.5 million and $10.7 million for the years ended December 31, 2011, 2010 and 2009, respectively.

We have a long-term sales contract with a subsidiary of Energy Transfer Equity. In addition, we and another subsidiary of ETP transport natural gas on each other’s systems and share operating expenses on certain pipelines. A subsidiary of ETP also sells natural gas to us. See previous table for related party revenue and expense amounts recorded by us in connection with our equity method investment in Energy Transfer Equity.

In January 2012, we sold 22,762,636 common units of Energy Transfer Equity in a private transaction (see Note 23). As a result of this sale, we own approximately 6 million common units of Energy Transfer Equity, which represent less than 3% of its common units outstanding at February 15, 2012. Effective with the first quarter of 2012, we will no longer report Energy Transfer Equity and its subsidiaries as related parties.

Note 16 . Provision for Income Taxes

Provision for income taxes primarily relates to our state tax obligations under the Revised Texas Franchise Tax (the “Texas Margin Tax”) and the federal and state tax obligations of our consolidated subsidiaries taxed as corporations. Deferred income tax assets and liabilities are recognized for temporary differences between the assets and liabilities of our tax paying entities for financial reporting and tax purposes.

We must recognize the tax effects of any uncertain tax positions we may adopt, if the position taken by us is more likely than not sustainable based on its technical merits. If a tax position meets such criteria, the tax effect that would be recognized by us would be the largest amount of benefit with more than a 50% chance of being realized.

Our federal and state income tax provision is summarized below:

	For Year Ended December 31,
	2011			2010			2009
Current:
Federal	$	(4.0	)	$	2.2		$	7.9

(1) These losses expire in various years between 2012 and 2028 and are subject to limitations on their utilization. (2) We record a valuation allowance to reduce our deferred tax assets to the amount of future benefit that is more likely than not to be realized.

In January 2012, we submitted applications to the Internal Revenue Service for the conversion of certain of our entities taxed as corporations into pass-through entities. If these conversions are approved, we expect to recognize an income tax benefit during the first quarter of 2012 of approximately $46.5 million, which is attributable to the difference between the deferred taxes accrued by these entities through the date of conversion and any current income tax due in connection with the conversion.

Note 17. Earnings Per Unit

As described below, the earnings per unit amounts presented in these consolidated financial statements have been retroactively adjusted to reflect the unit-for-unit exchange that occurred in connection with the Holdings Merger.

Basic and diluted earnings per unit amounts for periods prior to the Holdings Merger are based on net income attributable to partners divided by the weighted-average number of Holdings’ units outstanding for the period multiplied by the merger exchange ratio of 1.5 Enterprise common units for each Holdings unit. Net income attributable to partners prior to the Holdings Merger represents the net income allocated to the former owners of Holdings, which excluded amounts allocated to noncontrolling interests. As described in Note 13, net income attributable to noncontrolling interests prior to the Holdings Merger included net income amounts allocated to Enterprise’s limited partner interests that were owned by third parties and related parties other than Holdings.

Following the Holdings Merger, basic earnings per unit is computed by dividing net income or loss attributable to our limited partner interests by the weighted-average number of our distribution-bearing units outstanding during a period, which excludes the Designated Units (see Note 1) to the extent that such units do not participate in the distributions to be paid with respect to such period.

Diluted earnings per unit is computed by dividing net income or loss attributable to our limited partner interests by the sum of (i) the weighted-average number of our distribution-bearing units outstanding during a period (as used in determining basic earnings per unit), (ii) the weighted-average number of our Class B units (see Note 13) outstanding during a period, (iii) the weighted-average number of Designated Units outstanding during a period and (iv) the number of incremental common units resulting from the assumed exercise of dilutive unit options outstanding during a period (the “incremental option units”).

In a period of net losses, the Class B units, Designated Units and incremental option units are excluded from the calculation of diluted earnings per unit due to their antidilutive effect. The dilutive incremental option units are calculated using the treasury stock method, which assumes that proceeds from the exercise of all in-the-money options at the end of each period are used to repurchase common units at an average market price during the period. The amount of common units remaining after the proceeds are exhausted represents the potentially dilutive effect of the securities.

Note 18. 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 amounts can be reasonably estimated and no amount within the range is a better estimate than any other amount, then the minimum amount in the range is accrued.

We do not record a contingent liability when the likelihood of loss is probable but the amount cannot be reasonably estimated or when the likelihood of loss is believed to be only reasonably possible or remote. For contingencies where an unfavorable outcome is reasonably possible and the impact would be material, 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 (including the

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

availability of insurance coverage), we do not believe the ultimate outcome of any currently pending lawsuit against us will have a material impact on our financial statements individually or in the aggregate. See Note 19 for information regarding our insurance program.

At December 31, 2011 and 2010, litigation accruals on an undiscounted basis of $16.5 million and $8.6 million, respectively, were recorded in our 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 substantial 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.

Redelivery Commitments

We store natural gas, crude oil, NGLs and certain petrochemical products owned by third parties under various agreements. Under the terms of these agreements, we are generally required to redeliver volumes to the owner on demand. At December 31, 2011, we had approximately 7.0 trillion British thermal units of natural gas, 8.2 MMBbls of crude oil, and 27.5 MMBbls of NGL and petrochemical products in our custody that were owned by third parties. We maintain insurance coverage related to such volumes that we believe is consistent with our exposure. See Note 19 for information regarding insurance matters.

Contractual Obligations

Scheduled Maturities of Long-Term Debt . We have long-term and short-term payment obligations under debt agreements. Amounts shown in the preceding table represent our contractually scheduled future maturities of debt principal for the periods presented after taking into consideration the long-term refinancing of Senior Notes S and the TEPPCO Senior Notes due February 2012 using proceeds from the issuance of Senior Notes EE on February 15, 2012. See Notes 12 and 23 for additional information regarding our consolidated debt obligations.

ENTERPRISE PRODUCTS PARTNERS L.P.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Estimated Cash Interest Payments. Our estimated cash payments for interest are based on the principal amount of our consolidated debt obligations outstanding at December 31, 2011 and the scheduled maturities of such balances (after taking into account the issuance of Senior Notes EE and related refinancing activities noted above). With respect to our variable-rate debt obligations, we applied the weighted-average interest rate paid during 2011 to determine the estimated cash payments. See Note 12 for the weighted-average variable interest rates charged in 2011 under our credit agreements. In addition, our estimate of cash payments for interest gives effect to interest rate swap agreements that were in place at December 31, 2011. See Note 6 for information regarding these derivative instruments. Our estimated cash payments for interest are significantly influenced by the long-term maturities of our $550.0 million Junior Subordinated Notes A (due August 2066), $682.7 million Junior Subordinated Notes B (due January 2068), $285.8 million Junior Subordinated Notes C (due June 2067) and TEPPCO Junior Subordinated Notes (due June 2067). Our estimated cash payments for interest assume that these subordinated notes are not called prior to their respective maturity dates. We applied the current fixed interest rate through the respective maturity date for each junior subordinated note to determine the estimated cash payments for interest.

Operating Lease Obligations . We lease certain property, plant and equipment under noncancelable and cancelable operating leases. Amounts shown in the preceding table represent minimum cash lease payment obligations under our operating leases with terms in excess of one year.

Our significant lease agreements consist of (i) the lease of underground storage caverns for natural gas and NGLs, (ii) leased office space with affiliates of EPCO and (iii) land held pursuant to right-of-way agreements. In general, our material lease agreements have current terms that range from 14 to 20 years. The agreements for leased office space with affiliates of EPCO and underground NGL storage caverns we lease from a third party include renewal options that could extend these contracts for up to an additional 20 years. The remainder of our material lease agreements do not provide for additional renewal terms.

Lease expense is charged to operating costs and expenses on a straight-line basis over the period of expected economic benefit. Contingent rental payments are expensed as incurred. We are generally required to perform routine maintenance on the underlying leased assets. In addition, certain leases give us the option to make leasehold improvements. Maintenance and repairs of leased assets resulting from our operations are charged to expense as incurred. We did not make any significant leasehold improvements during the years ended December 31, 2011, 2010 or 2009.

Consolidated costs and expenses include lease and rental expense amounts of $86.2 million, $72.9 million and $60.7 million during the years ended December 31, 2011, 2010 and 2009, respectively.

Purchase Obligations . We define a purchase obligation as an agreement to purchase goods or services that is enforceable and legally binding (unconditional) on us that specifies all significant terms, including: fixed or minimum quantities to be purchased; fixed, minimum or variable price provisions; and the approximate timing of the transactions. We have classified our unconditional purchase obligations into the following categories:

We have long and short-term product purchase obligations for natural gas, NGLs, crude oil, refined products and certain petrochemicals with third party suppliers. The prices that we are obligated to pay under these contracts approximate market prices at the time we take delivery of the volumes. The preceding table shows our volume commitments and estimated payment obligations under these contracts for the periods presented. Our estimated future payment obligations are based on the contractual price in each agreement at December 31, 2011 applied to all future volume commitments. Actual future payment obligations may vary depending on prices at the time of delivery. At December 31, 2011, we did not have any significant product purchase commitments with fixed or minimum pricing provisions with remaining terms in excess of one year.

§	We have long and short-term commitments to pay service providers. Our contractual service payment commitments as shown in the preceding table primarily represent our obligations under

F-76

Table of Contents

ENTERPRISE PRODUCTS PARTNERS L.P.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

firm pipeline transportation contracts on pipelines owned by third parties and White River Hub. Payment obligations vary by contract, but generally represent a price per unit of volume multiplied by a firm transportation volume commitment.

We have short-term payment obligations relating to our capital spending program and those of our unconsolidated affiliates. These commitments represent unconditional payment obligations for services to be rendered or products to be delivered in connection with our capital projects. The preceding table presents our share of such commitments, including our share of those of our unconsolidated affiliates, for the periods presented.

Other Long-Term Liabilities

As reflected on our consolidated balance sheet at December 31, 2011, other long-term liabilities primarily represent the noncurrent portion of asset retirement obligations, deferred revenues and accrued pipeline transportation deficiency fees and interest rate derivative instruments.

Commitments Under Equity Compensation Plans of EPCO

In accordance with our agreements with EPCO, we reimburse EPCO for our share of its compensation expense associated with certain employees who perform management, administrative and operating functions for us (see Note 15). See Note 5 for additional information regarding our accounting for equity-based awards.

Other Claims

As part of our normal business activities with joint venture partners and certain customers and suppliers, we occasionally make claims against such parties or have claims made against us as a result of disputes related to contractual agreements or similar arrangements. As of December 31, 2011, our contingent claims against such parties were approximately $38.5 million and claims against us were approximately $46.1 million. These matters are in various stages of assessment and the ultimate outcome of such disputes cannot be reasonably estimated at this time; however, in our opinion, the likelihood of a material impact on our Consolidated Financial Statements from such disputes is remote. Accordingly, accruals for loss contingencies related to these matters have not been reflected in our Consolidated Financial Statements.

Centennial Guarantees

At December 31, 2011, Centennial’s debt obligations consisted of $101.9 million borrowed under a master shelf loan agreement. Borrowings under the master shelf agreement mature in May 2024 and are collateralized by substantially all of Centennial’s assets and severally guaranteed 50% by us and 50% by our joint venture partner in Centennial. If Centennial were to default on its debt obligations, we and our joint venture partner would each be required to make an approximate $51.0 million payment to Centennial’s lenders in connection with the guarantee agreements (based on Centennial’s debt principal outstanding at December 31, 2011). We recognized a liability of $7.2 million for our share of the Centennial debt guaranty at December 31, 2011.

In lieu of Centennial procuring insurance to satisfy third party claims arising from a catastrophic event, we and Centennial’s other joint venture partner have entered a limited cash call agreement. We are obligated to contribute up to a maximum of $50.0 million (in proportion to our 50% ownership interest in Centennial) in the event of a catastrophic event. At December 31, 2011, we have a recorded liability of $3.1 million representing the estimated fair value of our cash call guaranty. Our cash contributions to Centennial under the agreement may be covered by our other insurance policies depending on the nature of the catastrophic event.

Note 19 . Significant Risks and Uncertainties

Nature of Operations in Midstream Energy Industry

Our operations are within the midstream energy industry, which includes gathering, transporting, processing, fractionating and storing natural gas, NGLs, crude oil, refined products and certain petrochemicals. We also market natural gas, NGLs, crude oil and other hydrocarbon products. A reduction in demand for natural gas, NGLs, crude oil, refined products, petrochemicals and other hydrocarbon products by the petrochemical, refining or heating industries, whether because of general economic conditions; reduced demand by customers; increased competition from other products due to pricing differences; adverse weather conditions; government regulations affecting energy commodity prices, production levels of hydrocarbons or the content of motor gasoline; or other reasons, could adversely affect our financial position, results of operations and cash flows.

In April 2010, in an event unrelated to Enterprise’s operations, the Deepwater Horizon drilling rig caught fire and sank in the Gulf of Mexico, resulting in an oil spill. As a result, in May 2010, a federal offshore drilling moratorium went into effect which halted drilling of uncompleted and new oil and gas wells (in water deeper than 500 feet) in the Gulf of Mexico with certain limited exceptions and halted consideration of drilling permits for deepwater wells. The moratorium was lifted in October 2010; however, it is uncertain at this time how and to what extent oil and natural gas supplies from the Gulf of Mexico and other offshore drilling areas will be affected. A continued decline in oil and natural gas production volumes and/or a failure to achieve anticipated future production due to limitations instituted by governmental authorities (e.g., the federal offshore drilling moratorium) could have a material adverse effect on our financial position, results of operations or cash flows.

Credit Risk Due to Industry Concentrations

A substantial portion of our revenues are derived from companies in the domestic natural gas, NGL and petrochemical industries. This concentration could affect our overall exposure to credit risk since these customers may be affected by similar economic or other conditions. We generally do not require collateral for our accounts receivable; however, we do attempt to negotiate offset, prepayment, or automatic debit agreements with customers that are deemed to be credit risks in order to minimize our potential exposure to any defaults. See Note 14 for information regarding our largest customer.

Counterparty Risk with Respect to Derivative Instruments

In those situations where we are exposed to credit risk in our derivative instrument transactions, we analyze the counterparty’s financial condition prior to entering into an agreement, establish credit and/or margin limits and monitor the appropriateness of these limits on an ongoing basis. Generally, we do not require collateral nor do we anticipate nonperformance by our counterparties.

F-78

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Insurance-Related Risks

We participate as a named insured in EPCO’s insurance program, which provides us with property damage, business interruption and other insurance coverage, the scope and amounts of which we believe are customary and prudent for the nature and extent of our operations. While we believe EPCO maintains adequate insurance coverage on our behalf, insurance may not fully cover every type of damage, interruption or other loss that might occur. If we were to incur a significant loss for which we were not fully insured, it could have a material impact on our financial position, results of operations and cash flows. In addition, there may be a timing difference between amounts we recognize as expense and are required to pay in connection with a loss and the amounts we subsequently receive from insurance as reimbursement. Any event that materially interrupts the revenues generated by our consolidated operations, or other losses that require us to make material expenditures not reimbursed by insurance, could reduce our ability to pay distributions to our unitholders and, accordingly, adversely affect the market price of our common units.

Involuntary conversions result from the loss of an asset because of some uncontrollable event (e.g., destruction because of fire, government condemnation, and expropriation). Some of these events are insurable, thus resulting in a property damage insurance recovery. Amounts we receive from insurance are net of any deductibles related to the covered event. Currently, EPCO’s deductibles range from $5.0 million to $75.0 million depending on the nature of the loss (windstorm or non-windstorm) and the assets involved (onshore or offshore). We recognize an insurance receivable when realization of the claim for recovery of a loss recognized in the financial statements (e.g., an impairment charge related to destroyed assets) is deemed probable. To the extent that any of our claims are later judged not probable of recovery due to new information, such amounts are expensed. If no recovery is received, or the recovery is less than the net book value of the asset, a loss results. We recognize gains on involuntary conversions when the receipt of an insurance recovery is in excess of the net book value of the retired asset. In addition, we do not recognize gains related to insurance recoveries until all contingencies related to such proceeds have been resolved, that is, a non-refundable cash payment is received from the insurance carrier or we have a binding settlement agreement with the carrier that clearly states that a non-refundable payment will be made. To the extent that an asset is rebuilt, the associated expenditures are capitalized, as appropriate, on our Consolidated Balance Sheets and presented as capital expenditures on our Statements of Consolidated Cash Flows.

With respect to business interruption insurance claims, we recognize income only when we receive non-refundable cash proceeds from insurers, which are presented on the Statements of Consolidated Operations as a component of “Revenues.” The following table summarizes gains we recognized in connection with business interruption proceeds by segment during the years indicated:

	For Year Ended December 31,
	2011		2010		2009
NGL Pipelines & Services	$	4.3	$	--	$	4.3
Offshore Pipelines & Services (1)		--		1.1		28.9
Total gains recognized	$	4.3	$	1.1	$	33.2

(1) Gains recognized within this segment pertain to business interruption proceeds from hurricane claims in 2005 and 2008.

We received $64.8 million of insurance recoveries in 2010 related to the disposal of a segment of an offshore natural gas pipeline and certain components of an offshore platform. The $64.8 million of cash proceeds represents the negotiated insurance value of the covered assets and is a component of proceeds from asset sales and related transactions as presented on our Statements of Consolidated Cash Flows for the year ended December 31, 2010. Operating income for the year ended December 31, 2010 includes $56.6 million of net gains related to the disposition of these offshore assets.

product receipt and delivery capabilities and other measures, we readily returned our Mont Belvieu plants and related assets to close to the same capabilities as we had prior to the incident; however, our West Storage location and associated underground storage wells remain partially inoperative at this time. Remaining repairs to this location are underway and are expected to be completed in stages by mid-2012. We remain in negotiation with our insurance carriers regarding the overall claim, which is currently projected to be at least $150 million. As non-refundable insurance proceeds are received, we expect to record gains related to this incident.

In December 2011, we experienced a fire at our Falcon compressor station on the Jonah Gathering System. Following the incident, we rerouted natural gas production from the Pinedale Field, which had been compressed at the Falcon station, to other compressor stations on the Jonah system. As a result of piping modifications since the incident, we have restored the Jonah system to its full capabilities. As of December 31, 2011, we have recorded $5.3 million of losses related to this involuntary conversion event based on the difference between the net book value of the affected assets and our insurance claim receivable of approximately $15 million.

Operating income and gross operating margin for the years ended December 31, 2010 and 2009 include $26.4 million and $12.4 million of gains related to insurance recoveries due to property damage claims related to hurricane damages incurred in 2008 and 2005.

Regulatory Risks Involving Climate Change

Responding to scientific studies suggesting that emissions of gases, commonly referred to as “greenhouse gases,” including gases associated with oil and gas production such as carbon dioxide, methane and nitrous oxide among others, may be contributing to a warming of the earth’s atmosphere and other adverse environmental effects, the U.S. Congress has considered legislation to reduce emissions of greenhouse gases. The U.S. Environmental Protection Agency (“EPA”) has also taken action under the Federal Clean Air Act to regulate greenhouse gas emissions. In addition, some states, including states in which our facilities or operations are located, have taken or proposed legal measures to reduce emissions of greenhouse gases. There is considerable debate over global warming and the environmental effects of greenhouse gas emissions and associated consequences affecting global climate, oceans and ecosystems. As a commercial enterprise, we are not in a position to validate or repudiate the existence of global warming or various aspects of the scientific debate.

advantages to competing fuels and energy sources. The potential increase in the costs of our operations could include costs to operate and maintain our facilities, install new emission controls on our facilities, acquire allowances to authorize our greenhouse gas emissions, pay any taxes related to our greenhouse gas emissions, or administer and manage a greenhouse gas emissions program. While we may be able to include some or all of such increased costs in the rates charged by our pipelines or other facilities, such recovery of costs is uncertain and may depend on events beyond our control, including the provisions of any final regulations. In addition, changes in regulatory policies that result in a reduction in the demand for hydrocarbon products that are deemed to contribute to greenhouse gases, or restrictions on their use, may reduce volumes available to us for processing, transportation, marketing and storage.

Any of these climate change legislative or judicial initiatives or developments could have a material impact on our financial statements; however, we are unable to provide a range of estimated future costs due to the extreme uncertainty of such matters.

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 and production well tie-ins. These cash receipts are presented as “Contributions in aid of construction costs” within the investing activities section of our Statements of Consolidated Cash Flows.

In December 2011, we acquired the remaining noncontrolling 10% interest in Seminole for $15.0 million in cash. This acquisition was accounted for as an equity transaction.

Sale of 22.8 Million Common Units of Energy Transfer Equity

In January 2012, we sold 22,762,636 common units of Energy Transfer Equity in a private transaction, which generated cash proceeds of $825.1 million. Proceeds from this sale were used for general company purposes, including funding capital expenditures. Our Other Investments business segment consists of our investment in the common units of Energy Transfer Equity. As of the date of this report, we own approximately 6 million common units of Energy Transfer Equity, which represent less than 3% of its common units outstanding at February 15, 2012.

February 2012 Issuance of Senior Notes

On February 15, 2012, EPO issued $750.0 million in principal amount of 30-year unsecured Senior Notes EE at 99.542% of their principal amount. Senior Notes EE have a fixed interest rate of 4.85% and mature on August 15, 2042. Enterprise guaranteed the notes through an unconditional guarantee on an unsecured and unsubordinated basis. Net proceeds from the issuance of Senior Notes EE were used to temporarily reduce borrowings under our $3.5 Billion Multi-Year Revolving Credit Facility (which we used to repay outstanding amounts on the maturity of our $490.5 million principal amount of Senior Notes S due February 2012 and our $9.5 million principal amount of TEPPCO Senior Notes due February 2012 prior to the expected delivery of the notes) and for general company purposes.

Senior Notes EE rank equal with EPO’s existing and future unsecured and unsubordinated indebtedness. They are senior to any existing and future subordinated indebtedness of EPO. Senior Notes EE are subject to make-whole redemption rights and were issued under indentures 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.
