| SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies) | 12 Months Ended |
| Dec. 31, 2016 |
| Accounting Policies [Abstract] | |
| Basis of Presentation and Principles of Consolidation | Basis of Presentation and Principles of Consolidation The consolidated financial statements and the accompanying notes are prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and the rules of the U.S. Securities and Exchange Commission (“SEC”). The consolidated financial statements include the accounts of our subsidiaries controlled by us and variable interest entities (“VIEs”) of which we are the primary beneficiary. A VIE is required to be consolidated by its primary beneficiary which is generally defined as the party who has (i) the power to direct the activities of a VIE that most significantly impact the VIE’s economic performance and (ii) the obligation to absorb losses of the VIE or the right to receive benefits that could potentially be significant to the VIE. We evaluate our relationships with our VIEs on an ongoing basis to determine whether we continue to be the primary beneficiary. Third party or affiliate ownership interests in our subsidiaries and consolidated VIEs are presented as noncontrolling interests. All intercompany transactions are eliminated in consolidation. |
| Asset Retirement Obligations | Asset Retirement Obligations We regularly assess our legal obligations with respect to estimated retirements of certain of our long-lived assets to determine if an asset retirement obligation (“ARO”) exists. The fair value of a liability related to the retirement of long-lived assets is recorded at the time a regulatory or contractual obligation is incurred, including obligations to perform an asset retirement activity in which the timing or method of settlement are conditional on a future event that may or may not be within the control of the entity. If an ARO is identified and a liability is recorded, a corresponding asset is recorded concurrently and is depreciated over the remaining useful life of the asset. After the initial measurement, the liability is periodically adjusted for costs incurred or settled, accretion expense, and any revisions made to the assumptions related to the retirement costs. Generally, the fair value of the liability is determined based on estimates and assumptions related to: (i) future retirement costs; (ii) future inflation rates; and (iii) credit-adjusted risk-free interest rates. Our assets generally consist of terminals that we own and underground liquid petroleum products pipelines installed along rights-of-way acquired from land owners and related above-ground facilities. The significant majority of our rights-of-way agreements do not require the dismantling and removal of the pipelines and reclamation of the rights-of-way upon permanent removal of the pipelines from service. In addition, we assume substantially all of our common carrier properties operate indefinitely, as these assets generally serve in high-population and high-demand markets. Accordingly, other than with respect to facilities that are expected to be taken out of service, we have recorded no liabilities, or corresponding assets because the future dismantlement and removal dates of the majority of our assets, and the amount of any associated costs, are indeterminable. The ARO liability represents our best estimate of the costs to be incurred with information currently available and is based on certain assumptions, including: (i) timing of retirement of assets; (ii) methods of abandonment to be employed; and (iii) if applicable, our requirements under right-of-way agreements; therefore, it is likely that the ultimate costs to settle this liability will be different and such differences could be material. |
| Business Combinations | Business Combinations We allocate the total purchase price of a business combination to the assets acquired and the liabilities assumed based on their estimated fair values at the acquisition date, with the excess purchase price recorded as goodwill. For all material acquisitions, we engage an independent valuation specialist to assist us in determining the fair value of the assets acquired and liabilities assumed, including goodwill, based on recognized business valuation methodology. If the initial accounting for the business combination is incomplete by the end of the reporting period in which the acquisition occurs, an estimate will be recorded. Subsequent to the acquisition, and not later than one year from the acquisition date, we will record any material adjustments to the initial estimate in the reporting period in which the adjustment amounts are determined based on new information obtained about facts and circumstances that existed as of the acquisition date. An income, market or cost valuation method may be utilized to estimate the fair value of the assets acquired or liabilities assumed in a business combination. The income valuation method represents the present value of future cash flows over the life of the asset using: (i) discrete financial forecasts, which rely on management’s estimates of revenue and operating expenses; (ii) long-term growth rates; and (iii) appropriate discount rates. The market valuation method uses prices paid for a reasonably similar asset by other purchasers in the market, with adjustments relating to any differences between the assets. The cost valuation method is based on the replacement cost of a comparable asset at prices at the time of the acquisition reduced for depreciation of the asset. Also, we expense any acquisition-related costs as incurred in connection with each business combination. |
| Business Segments | Business Segments We operate and report in three business segments: (i) Domestic Pipelines & Terminals; (ii) Global Marine Terminals; and (iii) Merchant Services. See Note 25 for discussion of our business segments. |
| Capitalization of Interest | Capitalization of Interest Interest on borrowed funds is capitalized on projects during construction based on the approximate average interest rate of our debt. |
| Cash and Cash Equivalents | Cash and Cash Equivalents Cash equivalents represent all highly marketable securities with original maturities of three months or less. The carrying value of cash equivalents approximates fair value because of the short-term nature of these investments. |
| Comprehensive Income | Comprehensive Income Our comprehensive income is determined based on net income adjusted for unrealized gains and losses on derivative instruments for our cash flow hedging transactions, reclassification of derivative gains and losses to net income, recognition of costs related to our pension and post-retirement benefit plans and adjustments to the funded status of our pension and post-retirement benefit plans. |
| Concentration of Credit Risk and Trade Receivables | Concentration of Credit Risk and Trade Receivables Trade receivables of $228.5 million and $199.5 million as of December 31, 2016 and 2015 , respectively, are primarily due from major oil and natural gas companies, national oil companies, refiners, marketing and trading companies, and commercial airlines. These concentrations of customers may affect our overall credit risk as these customers may be similarly affected by changes in economic, regulatory or other factors. We extend credit to customers and manage our credit risks through credit analysis and monitoring procedures, including credit approvals, credit limits and right of offset. Also, we manage our risk using collateral, such as letters of credit, prepayments, liens on customer assets and guarantees. Trade receivables represent valid claims against non-affiliated customers and are recognized when products are sold or services are rendered. We record an allowance for doubtful accounts for estimated losses resulting from the inability of our customers to make required payments. We review the adequacy of the allowance for doubtful accounts monthly by making judgments regarding future events and trends based on the: (i) customers’ historical relationship with us; (ii) customers’ current financial condition; and (iii) current and projected economic conditions. |
| Construction and Pipeline Relocation Receivables | Construction and Pipeline Relocation Receivables Construction and pipeline relocation receivables represent valid claims against non-affiliated customers for services rendered in constructing or relocating pipelines and are recognized when services are rendered. |
| Contingencies | Contingencies Certain conditions may exist as of the date our consolidated financial statements are issued that may result in a loss to us, but which will only be resolved when one or more future events occur or fail to occur. Our management, with input from legal counsel, assesses such contingent liabilities, and such assessment inherently involves judgment. In assessing loss contingencies related to legal proceedings that are pending against us or unasserted claims that may result in proceedings, our management, with input from legal counsel, evaluates 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. If the assessment of a contingency indicates that it is probable that a loss has been incurred and the amount of liability can be estimated, then the estimated liability is accrued in our consolidated financial statements. If the assessment indicates that a potentially material loss contingency is not probable but is reasonably possible, or is probable but cannot be estimated, then the nature of the contingent liability, together with an estimate of the range of possible loss if determinable and material, is disclosed. Actual results could vary from these estimates and judgments. Loss contingencies considered remote are generally not disclosed unless they involve guarantees, in which case the guarantees would be disclosed. |
| Cost of Product Sales | Cost of Product Sales Cost of product sales relates to sales of refined petroleum products, consisting primarily of gasoline, propane, ethanol, biodiesel and middle distillates, such as heating oil, diesel fuel and kerosene, and fuel oil, as well as the effects of hedges of refined petroleum product acquisition costs and hedges of fixed-price contracts. |
| Debt Issuance Costs | Debt Issuance Costs Costs incurred upon the issuance of our debt instruments are capitalized and amortized over the life of the associated debt instrument on a straight-line basis, which approximates the effective interest method. If the debt instrument is retired before its scheduled maturity date, any remaining issuance costs associated with that debt instrument are expensed in the same period. |
| Derivative Instruments | Derivative Instruments Derivatives are financial and physical instruments whose fair value is determined by changes in a specified benchmark such as interest rates or commodity prices. We use derivative instruments such as forwards, futures, swaps and other contracts to manage market price risks associated with inventories, firm commitments, interest rates and certain forecasted transactions. We do not engage in speculative trading activities. We recognize these transactions on our consolidated balance sheets as assets and liabilities based on the instrument’s fair value. Changes in fair value of derivative instrument contracts are recognized in the current period in earnings unless specific hedge accounting criteria are met. If the derivative instrument is designated as a hedging instrument in a fair value hedge, gains and losses incurred on the instrument will be recorded in earnings to offset corresponding losses and gains on the hedged item. If the derivative instrument is designated as a hedging instrument in a cash flow hedge, gains and losses incurred on the instrument are recorded in other comprehensive income. Any gains or losses incurred on the derivative instrument that are not effective in offsetting changes in fair value or cash flows of the hedged item are recognized immediately in earnings. Gains and losses on cash flow hedges are reclassified from accumulated other comprehensive income (“AOCI”) to earnings when the forecasted transaction occurs and affects net income or, as appropriate, over the economic life of the underlying asset or liability. Gains and losses related to a derivative instrument designated as a hedge of a forecasted transaction that is no longer likely to occur is immediately recognized in earnings. Physical forward contracts and futures contracts that have not been designated in a hedge relationship are marked-to-market. To qualify as a hedge, the item to be hedged must expose us to risk and we must have an expectation that the related hedging instrument will be effective at reducing or mitigating that exposure. In accordance with the hedging requirements, we document all hedging relationships at inception and include a description of the risk management objective and strategy for undertaking the hedge, identification of the hedging instrument, the hedged item, the nature of the risk being hedged, the method for assessing effectiveness of the hedging instrument in offsetting the hedged risk and the method of measuring any ineffectiveness. We link all derivative instruments that are designated as fair value or cash flow hedges to specific assets and liabilities on our consolidated balance sheets or to specific firm commitments or forecasted transactions. When an event or transaction occurs, such as the sale of hedged fuel inventory or the expiration of derivative contracts, we discontinue hedge accounting. We also formally assess, both at the hedge’s inception and on an ongoing basis, whether the derivative instruments that are used in designated hedging relationships are highly effective in offsetting changes in fair values or cash flows of hedged items. If it is determined that a derivative instrument is not highly effective as a hedge or that it has ceased to be a highly effective hedge, we discontinue hedge accounting prospectively. We measure ineffectiveness by comparing the change in fair value of the hedge instrument to the change in fair value of the hedged item. The time value component is excluded from our hedge assessment and reported directly in earnings. |
| Discontinued Operations | Discontinued Operations In December 2013, the Board of Directors of Buckeye GP (the “Board”) approved a plan to divest the natural gas storage facility and related assets that our former subsidiary, Lodi Gas Storage, L.L.C. (“Lodi”), owned and operated in Northern California. We refer to this group of assets as our Natural Gas Storage disposal group. The results of operations for our Natural Gas Storage disposal group have been segregated and presented as discontinued operations for all periods presented in these financial statements. On December 31, 2014, we completed the sale of our Natural Gas Storage disposal group and have reported the final working capital adjustments as discontinued operations in the first quarter of 2015. See Note 4 and Note 5 for additional information. |
| Earnings per Unit | Earnings per Unit Basic earnings per unit from continuing operations, which includes LP Units, is determined by dividing our income from continuing operations, after deducting the amount allocated to noncontrolling interests, by the weighted average units outstanding for the period. Diluted earnings per unit from continuing operations is calculated using the same methodology, except the weighted average units outstanding includes any dilutive effect of LP Unit option grants or grants under the 2013 Long-Term Incentive Plan of Buckeye Partners, L.P. (the “LTIP”). A similar calculation is performed for basic and diluted earnings per unit from discontinued operations, except loss from discontinued operations is divided by the weighted average units outstanding for the period. |
| Environmental Expenditures | Environmental Expenditures We are subject to federal, state and local laws and regulations relating to the protection of the environment, which require us to remove or remedy the effect of the disposal or release of specified substances at our operating sites. We record environmental liabilities at a specific site when environmental assessments indicate remediation efforts are probable, and costs can be reasonably estimated based upon past experience, discussions with operating personnel, advice of outside engineering and consulting firms, discussion with legal counsel or current facts and circumstances. The estimates related to environmental matters are uncertain because: (i) estimated future expenditures are subject to cost fluctuations and change in estimated remediation period; (ii) unanticipated liabilities may arise; and (iii) changes in federal, state and local environmental laws and regulations may significantly change the extent of remediation. Our estimated environmental remediation liabilities are not discounted to present value since the ultimate amount and timing of cash payments for such liabilities are not readily determinable. Expenditures to mitigate or prevent future environmental contamination are capitalized. We monitor the environmental liabilities regularly and record adjustments to our initial estimates, from time to time, to reflect changing circumstances and estimates based upon additional developments or information obtained in subsequent periods. We maintain insurance which may cover certain environmental expenditures. Recoveries of environmental remediation expenses from other parties are recorded when their receipt is deemed probable. |
| Equity Investments | Equity Investments We account for investments in entities in which we do not exercise control, but have significant influence, using the equity method of accounting. Under this method, an investment is recorded at acquisition cost plus our equity in undistributed earnings or losses since acquisition, reduced by distributions received and amortization of excess net investment. Excess investment is the amount by which the total investment exceeds the proportionate share of the book value of the net assets of the investment. Such excess investment not related to any specific accounts of the investee are treated as goodwill and not amortized. Amounts associated with specific accounts of the investee are amortized. We evaluate equity method investments for impairment whenever events or changes in circumstances indicate that there is an “other than temporary” loss in value of the investment. In the event that the loss in value of an investment is “other than temporary”, we record a charge to earnings to adjust the carrying value to fair value. Estimates of future cash flows that would be used to determine fair value include: (i) discrete financial forecasts, which rely on management’s estimates of revenue and operating expenses; (ii) long-term growth rates; and (iii) probabilities assigned to different cash flow scenarios. A significant change in these underlying assumptions could result in an impairment charge. |
| Estimates | Estimates The preparation of consolidated financial statements in conformity with GAAP requires our management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses during the reporting period and disclosure of contingent assets and liabilities at the date of the consolidated financial statements. Estimates and assumptions about future events and their effects cannot be made with certainty. Estimates may change as new events occur, when additional information becomes available and if our operating environment changes. Actual results could differ from our estimates. |
| Fair Value Measurements | Fair Value Measurements Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at a specified measurement date. 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 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 characteristics of fair value amounts classified within each level of the hierarchy are described as follows: • Level 1 inputs — unadjusted quoted prices which are available in active markets for identical, unrestricted assets or liabilities as of the reporting date; • Level 2 inputs — quoted market prices in markets that are not considered to be active or financial instruments for which all significant inputs are observable, either directly or indirectly; and • Level 3 inputs — prices or valuations that require inputs that are both significant to the fair value measurement and unobservable. These inputs are typically used in connection with internally developed valuation methodologies where management makes its best estimate of an instrument’s fair value. We categorize our financial assets and liabilities using this hierarchy at each balance sheet reporting date. |
| Foreign Currency | Foreign Currency Puerto Rico is a commonwealth country under the U.S., and thus uses the U.S. dollar as its official currency. The functional currency of our operations in BBH and St. Lucia is the U.S. dollar. Foreign exchange gains and losses arising from transactions denominated in a currency other than the U.S. dollar relate to a nominal amount of supply purchases and are included in “Other income (expense)” within the consolidated statements of operations. |
| Goodwill | Goodwill Goodwill represents the excess of purchase price over fair value of net assets acquired. Our goodwill amounts are assessed for impairment: (i) on an annual basis on October 31st each year or (ii) on an interim basis if circumstances indicate it is more likely than not the fair value of a reporting unit is less than its fair value. Goodwill is tested for impairment at a level of reporting referred to as a reporting unit. A reporting unit is a business segment or one level below a business segment for which discrete financial information is available and regularly reviewed by segment management. Our reporting units are our business segments, with the exception of our Global Marine Terminals segment. Our reporting units to which goodwill has been allocated in our Global Marine Terminals segment consist of the following: (i) our operations in the Caribbean and New York Harbor; and (ii) our operations in Buckeye Texas. We may perform a qualitative assessment to determine whether the fair value of our reporting units are more likely than not less than the carrying amount. If we believe the fair value is less than the carrying amount, we will perform step one of the two-step goodwill impairment test. The first step of the goodwill impairment test determines whether an impairment exists by comparing the fair value of a reporting unit with its carrying amount, including goodwill. If the estimated fair value of the reporting unit exceeds its carrying amount, no impairment is indicated. If the carrying amount of a reporting unit exceeds its estimated fair value, an impairment is indicated and the second step of the test is performed to measure the amount of impairment by comparing the implied fair value of the reporting unit goodwill to the carrying amount of that goodwill. The fair value of the reporting unit is allocated to all of the assets and liabilities of that unit as if the reporting unit had been acquired in a business combination. The excess of the fair value of the reporting unit over the amounts assigned to its assets and liabilities is the implied fair value of goodwill. The estimate of the fair value of the reporting unit is determined using a combination of an expected present value of future cash flows and a market multiple valuation method. The present value of future cash flows is estimated using: (i) discrete financial forecasts, which rely on management’s estimates of revenue and operating expenses; (ii) long-term growth rates; and (iii) appropriate discount rates. The market multiple valuation method uses appropriate market multiples from comparable companies on the reporting unit’s earnings before interest, tax, depreciation and amortization. We evaluate industry and market conditions for purposes of weighting the income and market valuation approach. |
| Income Taxes | Income Taxes For U.S. federal income tax purposes, we and each of our subsidiaries, except for Buckeye Development & Logistics I LLC (“BDL”), are not taxable entities. Accordingly, our taxable income, except for BDL, is generally includable in the U.S. federal income tax returns of our individual partners and 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. In certain states in which we operate, our operating subsidiaries directly incur income-based state taxes, which are subject to examination by state taxing authorities. In addition, outside the continental U.S., our operations at BBH and St. Lucia are exempt from income taxes. Our operations at BBH are tax exempt by the Bahamian government pursuant to concessions granted under the Hawksbill Creek Agreement between the Government of The Bahamas and the Grand Bahama Port Authority. These concessions expired in May 2016 but have been extended through May 2036 by the Grand Bahama Investment Incentives Act, subject to an application process that must be completed by March 2017. Our operations in St. Lucia are exempt from income taxes and duties pursuant to concessions granted under the terms of a tax concession agreement effective in 2007 and in effect for a minimum of 50 years . Our operations at the Yabucoa terminal are subject to income taxes within the Commonwealth of Puerto Rico. Buckeye Caribbean Terminals LLC (“Buckeye Caribbean”) files annual income tax returns with the Puerto Rico Treasury Department and in 2002, was granted partial exemption under the Tax Incentives Act of 1998 (the “Act”). Under the current terms of the grant, Buckeye Caribbean is subject to an income tax rate of 4% to 7% on industrial development income. The grant also provides additional exemptions as follows: (i) 90% exempt from real and personal property taxes; (ii) 60% exempt from municipal taxes on industrial development income; and (iii) 100% exempt from excise taxes imposed under Subtitle C of the Puerto Rico Internal Revenue Code, to the extent provided in Section 6(c) of the Act. This favorable tax rate is scheduled to expire in 2022. We recognize deferred tax assets and liabilities for temporary differences between the amounts of assets and liabilities measured for financial reporting purposes and federal income tax purposes. Changes in tax legislation are included in the relevant computations in the period in which such changes are effective. We evaluate the need for a valuation allowance and consider all available positive and negative evidence, including projected operating income or losses for the foreseeable future, to determine the likelihood of realizing the benefits of deferred tax assets. If the value of the deferred tax assets exceeds the estimated future benefit, 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 the future, if the realization of the deferred tax assets should occur, a reduction to the valuation allowance related to the deferred tax assets would increase net income in the period such determination is made. |
| Intangible Assets | Intangible Assets Intangible assets with finite useful lives are reviewed for impairment when events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. Intangible assets that have finite useful lives are amortized over their useful lives. Intangible assets include contracts and customer relationships. The fair values of these intangibles are based on the present value of cash flows attributable to the customer relationship or contract, which includes management’s estimates of revenue and operating expenses and costs relating to utilization of other assets to fulfill such contracts. The customer contracts are being amortized over their contractual lives with a range of 1 to 10 years . For the customer relationships, we determine the recovery period based on historical customer attrition rates and management’s assumptions on future events, including customer demand, contract renewal, useful lives of related assets and market conditions. The customer relationships are being amortized over the estimated recovery period of 12 to 20 years . When necessary, intangible assets’ useful lives are revised and the impact on amortization is reflected on a prospective basis. |
| Inventories | Inventories We generally maintain two types of inventory. Our Merchant Services segment principally maintains refined petroleum products inventory, consisting of gasoline, propane, ethanol, biodiesel and middle distillates, such as heating oil, diesel fuel and kerosene. Inventory is valued at the lower of weighted average cost or net realizable value, unless such inventories are hedged. Net realizable value is defined as the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. Hedged inventory is adjusted for the effects of applying fair value hedge accounting. We also maintain, principally within our Domestic Pipelines & Terminals segment, an inventory of materials and supplies such as pipes, valves, pumps, electrical/electronic components, drag reducing agent and other miscellaneous items that are valued at the lower of weighted average cost or net realizable value. |
| Long-lived Assets | Long-Lived Assets We assess the recoverability of our long-lived assets whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. We determine the estimated undiscounted future cash flows expected to result from the use of the asset and its eventual disposal. If the sum of the estimated undiscounted future cash flows exceeds the carrying amount, no impairment is necessary. If the carrying amount exceeds the sum of the undiscounted cash flows, an impairment charge is recognized based on the amount by which the carrying amount of the assets exceeds the estimated fair value of the assets. Assets to be disposed of are reported at the lower of the carrying amount or estimated fair value less costs to sell. Estimates of undiscounted future cash flows include: (i) discrete financial forecasts, which rely on management’s estimates of revenue and operating expenses; (ii) long-term growth rates; and (iii) estimates of useful lives of the assets. Such estimates of future undiscounted net cash flows are highly subjective and are based on numerous assumptions about future operations and market conditions. |
| Net Income Allocation | Net Income Allocation We allocate the net income attributable to Buckeye to the LP Unitholders based on the weighted average LP Units outstanding during the period. |
| Noncontrolling Interests | Noncontrolling Interests The consolidated balance sheets and statements of operations include noncontrolling interests that relate primarily to Buckeye Texas, Buckeye Pipe Line Services Company (“Services Company”) and the Sabina crude butadiene pipeline (the “Sabina Pipeline”) that are not owned by Buckeye. |
| Pensions and Postretirement Benefits | Pensions and Postretirement Benefits Services Company sponsors a defined contribution plan, a defined benefit plan and the Employee Stock Ownership Plan (“ESOP”) that provide retirement benefits to certain regular full-time employees. Services Company also sponsors an unfunded post-retirement plan that provides health care and life insurance benefits for certain of its retirees. We develop pension and postretirement health care and life insurance benefits costs from actuarial valuations. The measurement of expenses and liabilities related to these plans is based on management’s assumptions related to future events, including discount rate, expected return on plan assets, rate of compensation increase, and health care cost trend rates. The actuarial assumptions that we use may differ from actual results due to changing market rates or other factors. These differences could affect the amount of pension and postretirement health care and life insurance benefit expense we have recorded or may record. |
| Property, Plant and Equipment | Property, Plant and Equipment We record property, plant and equipment at its original acquisition cost. Property, plant and equipment consist primarily of pipelines, terminals, storage and processing facilities, jetties, subsea pipelines and docks, and pumping and station equipment. Generally, we depreciate property, plant and equipment based on the straight-line method over the estimated useful lives, except for land. See Note 9 for the depreciation life of our assets. Additions to property, plant and equipment, including maintenance and expansion and cost reduction capital expenditures, are recorded at cost. Maintenance capital expenditures maintain and enhance the safety and integrity of our pipelines, terminals, storage and processing facilities, and related assets, and expansion and cost reduction capital expenditures expand the reach or capacity of those assets, to improve the efficiency of our operations and to pursue new business opportunities. We charge repairs to expense in the period incurred. The cost of property, plant and equipment sold or retired and the related depreciation, except for certain pipeline system assets, are removed from our consolidated balance sheet in the period of sale or disposition, and any resulting gain or loss is included in earnings. For our pipeline system assets, we generally charge the original cost of property sold or retired to accumulated depreciation and amortization, net of salvage and cost of removal. When a separately identifiable group of assets, such as a stand-alone pipeline system is sold, we will recognize a gain or loss in our consolidated statements of operations for the difference between the cash received and the net book value of the assets sold. |
| Recent Accounting Developments | Recent Accounting Developments Goodwill Impairment . In January 2017, the Financial Accounting Standards Board (“FASB”) issued guidance simplifying the test for goodwill impairment. The guidance eliminates Step 2 from the goodwill impairment test, which required entities to calculate the implied fair value of a reporting unit's goodwill by assigning the fair value of a reporting unit to all of its assets and liabilities as if that reporting unit had been acquired in a business combination. Under the new guidance, entities will recognize an impairment charge for the amount by which the fair value of a reporting unit exceeds its carrying amount. The guidance must be applied using a prospective approach and is effective for interim and annual goodwill impairment tests in fiscal years beginning after December 15, 2019, with early adoption permitted. We do not believe our adoption of this guidance will have a material impact on our consolidated financial statements or on our disclosures. Business Combinations . In January 2017, the FASB issued guidance clarifying the definition of a business in order to assist entities with evaluating whether transactions should be accounted for as acquisitions/disposals of assets or businesses. The guidance provides a screen to help entities determine when an integrated set of assets and activities is not a business. The screen requires that when substantially all of the fair value of the gross assets acquired (or disposed of) is concentrated in a single identifiable asset or a group of similar identifiable assets, the set of assets is not a business. If the threshold of the screen is not met, the guidance further clarifies that the set of assets is not a business unless it includes an input and a substantive process that together significantly contribute to the ability to create output. The guidance must be applied using a prospective approach and is effective for annual reporting periods beginning after December 15, 2017 and interim periods within those annual periods, with early adoption permitted for specific transactions. We are currently evaluating the impact the adoption of this guidance will have on our consolidated financial statements. Statement of Cash Flows . In August 2016, the FASB issued guidance to address how certain cash receipts and cash payments are presented and classified in the statement of cash flows, with the objective of reducing existing diversity in practice with respect to these items. The guidance must be applied retrospectively, and it is effective for annual reporting periods beginning after December 15, 2017 and interim periods within those annual periods, with early adoption permitted. We are currently evaluating the impact the adoption of this guidance will have on our consolidated financial statements. Equity-Based Compensation . In March 2016, the FASB issued guidance to simplify several aspects of the accounting for employee equity-based payment transactions, including the accounting for income taxes, forfeitures and statutory tax withholding requirements, as well as classification in the statement of cash flows and classification of awards as liabilities or equity. The guidance is effective for annual reporting periods beginning after December 15, 2016 and interim periods within those annual periods, with early adoption permitted. Amendments related to the timing of when excess tax benefits are recognized, statutory withholding requirements and forfeitures should be applied using a modified retrospective transition method by means of a cumulative-effect adjustment to equity as of the beginning of the period in which the guidance is adopted. Amendments related to the presentation of employee taxes paid on the statement of cash flows should be applied retrospectively. Amendments requiring recognition of excess tax benefits and tax deficiencies in the income statement should be applied prospectively. Amendments related to the presentation of excess tax benefits on the statement of cash flows may be applied using either a prospective transition method or a retrospective transition method. We do not believe our adoption of this guidance will have a material impact on our consolidated financial statements or on our disclosures. Leases . In February 2016, the FASB issued guidance requiring lessees to recognize assets and liabilities for leases with lease terms greater than twelve months in the statement of financial position. This update also requires enhanced disclosures regarding the amount, timing and uncertainty of cash flows arising from leases. The guidance must be applied using a modified retrospective approach and is effective for annual reporting periods beginning after December 15, 2018 and interim periods within those annual periods, with early adoption permitted. We are currently evaluating the impact the adoption of this guidance will have on our consolidated financial statements. Revenue from Contracts with Customers . In May 2014, the FASB issued Accounting Standards Update No. 2014-09, “Revenue from Contracts with Customers (Topic 606)” (“ASU 2014-09”), which amended existing accounting standards for revenue recognition, including industry-specific requirements, and provides entities with a single revenue recognition model for recognizing revenue from contracts with customers. The core principle of ASU 2014-09 is that an entity should recognize revenue from contracts with customers when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Furthermore, additional disclosures will be required to describe the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts. The two permitted transition methods under ASU 2014-09 are the full retrospective method, which would be applied to each prior reporting period presented and the cumulative effect of applying the standard would be recognized at the earliest period shown, or the modified retrospective method, in which the cumulative effect of applying the standard would be recognized at the date of initial application. In July 2015, the FASB deferred the effective date of ASU 2014-09 and is effective for annual and interim periods beginning after December 15, 2017, with early adoption permitted for annual and interim periods beginning after December 15, 2016. In 2016, the FASB issued accounting standards updates that amended several aspects of ASU 2014-09. We are currently evaluating the provisions of the standard and have formed an implementation work team consisting of representatives from across all of our business segments to evaluate and implement changes to business processes, systems and controls. In addition, we have implemented training on the new standard's revenue recognition model and are continuing our contract review and documentation. We expect to adopt this guidance on January 1, 2018, and we are currently evaluating the impact and the transition alternatives it will have on our consolidated financial statements. |
| Revenue Recognition | Revenue Recognition Domestic Pipelines & Terminals segment . Revenue from pipeline operations is comprised of tariffs and fees associated with the transportation of liquid petroleum products or crude oil at published tariffs as well as revenue associated with line leases for committed capacity on a particular system. Tariff revenue is recognized either at the point of delivery or at the point of receipt, pursuant to specifications outlined in the respective tariffs. Revenue associated with line leases is recognized ratably over the respective lease terms, regardless of whether the capacity is actually utilized, and is subject to take-or-pay arrangements. All pipeline tariff and fee revenue is based upon actual volumes and rates. As is common in the industry, our tariffs incorporate loss allocation or loss allowance factors that are intended to, among other things, offset losses due to evaporation, measurement and other product losses in transit. We value the variance of allowance volumes to actual losses at the estimated net realizable value at the time the variance occurred, and the result is recorded as either an increase or decrease to transportation and other service revenue. In addition, we have certain agreements that require counterparties to ship a minimum volume over an agreed-upon period. Revenue pursuant to such agreements is recognized at the earlier of when the volume is shipped or when the counterparty’s ability to meet the minimum volume commitment has expired. Revenue from terminalling and storage operations is recognized as services are performed. Storage and terminalling revenue include storage fees, which are generated when we provide storage capacity, and terminalling or throughput fees, which are generated when we receive liquid petroleum products from one connecting pipeline and redeliver such products to another connecting carrier or to customers through a truck-loading rack. We generate revenue through a combination of month-to-month and multi-year storage capacity and terminalling service arrangements. Storage fees resulting from short-term and long-term contracts are typically recognized in revenue ratably over the term of the contract, regardless of the actual storage capacity utilized. Terminalling fees are recognized as the refined petroleum product or crude oil exits the terminal and is delivered to a connecting carrier, third-party terminal or a customer through a truck-loading rack. In addition, we have certain agreements that require counterparties to throughput a minimum volume over an agreed-upon period. Revenue pursuant to such agreements is recognized at the earlier of when the volume exits the terminal or when the counterparty’s ability to meet the minimum volume commitment has expired. Butane blending revenues are recognized as blending activities are completed and include the change in the fair value of financial derivative instruments used to manage the commodity price risk associated with narrowing gasoline-to-butane pricing spreads. Revenue from contract operation and construction services of facilities and pipelines not directly owned by us is recognized as the services are performed. Contract and construction services revenue typically includes costs to be reimbursed by the customer plus an operator fee. Global Marine Terminals segment . Revenue from terminalling and storage operations is recognized as the services are performed. Storage and terminalling revenue includes storage fees, which are generated when we provide storage capacity, and terminalling or throughput fees, which are generated when we receive liquid petroleum products from sea going vessels, pipelines, trucks, or rail and redeliver such products to customers through marine applications, truck-loading racks, and pipelines. We generate revenue through a combination of storage capacity, terminalling and tolling service arrangements. Storage fees resulting from short-term and long-term contracts are typically recognized in revenue ratably over the term of the contract, regardless of the actual storage capacity utilized. Terminalling fees are recognized as the liquid petroleum product exits the terminal and is delivered to a connecting carrier, third-party terminal or a customer through a truck-loading rack or vessel. Tolling agreement fees are recognized ratably over the term of the contract and are based on minimum volume and product specification requirements. In addition, we have agreements that require counterparties to throughput a minimum volume over an agreed-upon period. Revenue pursuant to such agreements is recognized at the earlier of when the volume exits the terminal or when the counterparty’s ability to meet the minimum volume has expired. Revenue from other ancillary services is recognized in the accounting period in which the services are rendered. Merchant Services segment . Revenue from the sale of petroleum products, including fuel oil, which are sold on a wholesale basis, is recognized at the time title to the product sold transfers to the purchaser, which occurs upon delivery of the product to the purchaser or its designee. We enter into exchange contracts and matching buy/sell arrangements whereby we agree to deliver a particular quantity and quality of crude oil or refined products at a specified location and date to a particular counterparty and to receive from the same counterparty the same or similar commodity at a specified location on the same or another specified date. The exchange receipts and deliveries are nonmonetary transactions, with the exception of associated grade or location differentials that are settled in cash. The matching buy/sell purchase and sale transactions are settled in cash. Both exchange and matching buy/sell transactions are accounted for as exchanges of inventory, and pricing differentials are recorded in “Product sales” revenues. The exchange transactions are recognized at the carrying amount of the inventory transferred. |
| Unit-Based Compensation | Unit-Based Compensation We award unit-based compensation to employees and directors primarily under the LTIP. All unit-based payments to employees under the LTIP, including grants of phantom units and performance units, are recognized in our consolidated statements of operations based on their fair values. The fair values of both the performance unit and phantom unit grants are based on the average market price of our LP Units on the date of grant as adjusted for certain market-based conditions. Compensation expense equal to the fair value of those performance unit and phantom unit awards that are expected to vest is estimated and recorded over the period the grants are earned, which is the vesting period. Compensation expense estimates are updated periodically. The vesting of the performance unit awards is also contingent upon the attainment of predetermined performance goals. Depending on the estimated probability of attainment of those performance goals, the compensation expense recognized related to the awards could increase or decrease over the remaining vesting period. |
| Variable Interest Entities | Variable Interest Entities We evaluate our financial interests in business enterprises to determine if they represent VIEs of which we are the primary beneficiary. If such criteria are met (as discussed above in “Basis of Presentation and Principles of Consolidation”), we reflect these entities as consolidated subsidiaries. There were no changes to the entities consolidated for the year ended December 31, 2016 . Buckeye Texas and Sabina Pipeline are VIEs of which we are the primary beneficiary. We own an 80% interest in Buckeye Texas (see Note 3 for more information) and also own a 63% interest in Sabina Pipeline. Third party or affiliate ownership interests in our consolidated VIEs are presented as noncontrolling interests. |
