Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
General | 1. General Description of Business SunCoke Energy Partners, L.P., (the "Partnership," "we," "our" and "us"), primarily produces coke used in the blast furnace production of steel. Coke is a principal raw material in the blast furnace steelmaking process and is produced by heating metallurgical coal in a refractory oven, which releases certain volatile components from the coal, thus transforming the coal into coke. We also provide handling and/or mixing services of coal and other aggregates at our logistics terminals. At December 31, 2017 , we owned a 98 percent interest in Haverhill Coke Company LLC ("Haverhill"), Middletown Coke Company, LLC ("Middletown") and Gateway Energy and Coke Company, LLC ("Granite City") and SunCoke Energy, Inc. ("SunCoke") owned the remaining 2 percent interest in each of Haverhill, Middletown, and Granite City. The Partnership also owns a 100 percent interest in all of its logistics terminals. Through its subsidiary, SunCoke owned a 59.9 percent limited partnership interest in us and indirectly owned and controls our general partner, which holds a 2 percent general partner interest in us and all of our incentive distribution rights ("IDRs"). Our cokemaking ovens have collective capacity to produce 2.3 million tons of coke annually and utilize efficient, modern heat recovery technology designed to combust the coal’s volatile components liberated during the cokemaking process and use the resulting heat to create steam or electricity for sale. This differs from by-product cokemaking, which seeks to repurpose the coal’s liberated volatile components for other uses. We have constructed the only greenfield cokemaking facilities in the United States ("U.S.") in approximately 30 years and are the only North American coke producer that utilizes heat recovery technology in the cokemaking process. We provide steam pursuant to steam supply and purchase agreements with our customers. Electricity is sold into the regional power market or pursuant to energy sales agreements. Our logistics business provides coal handling and/or mixing services to steel, coke (including some of our domestic cokemaking facilities), electric utility and coal mining customers. The logistics business has terminals in Indiana, West Virginia, and Louisiana with the collective capacity to mix and/or transload more than 40 million tons of coal annually and has total storage capacity of approximately 3 million tons. We were organized in Delaware in 2012 and are headquartered in Lisle, Illinois. We became a publicly-traded partnership in 2013, and our stock is listed on the New York Stock Exchange (“NYSE”) under the symbol “SXCP.” Consolidation and Basis of Presentation The combined and consolidated financial statements of the Partnership and its subsidiaries were prepared in accordance with accounting principles generally accepted in the U.S. ("GAAP") and include the assets, liabilities, revenues and expenses of the Partnership and all subsidiaries where we have a controlling financial interest. Intercompany transactions and balances have been eliminated in consolidation. Net income attributable to noncontrolling interest represents SunCoke's respective ownership interest in Haverhill, Middletown and Granite City during years ended December 31, 2017 , 2016 and 2015 . During 2015, we acquired a 98 percent interest in Granite City, 75 percent of which was acquired on January 13, 2015 ("Granite City Dropdown") and 23 percent of which was acquired on August 12, 2015 ("Granite City Supplemental Dropdown"). The Granite City Dropdown was a transfer of businesses between entities under common control. Accordingly, our historical financial information has been retrospectively adjusted to include the historical consolidated results and financial position of the Partnership combined with SunCoke’s historical results and financial position of Granite City, (the “Previous Owner”), after the elimination of all intercompany accounts and transactions. The Granite City historical results before the Granite City Dropdown are referred to as income attributable to Previous Owner on the Combined and Consolidated Statements of Operations. The Granite City Dropdown did not impact historical earnings per unit as pre-acquisition earnings were allocated to our general partner. |

Accounting Policies [Abstract] | |
Significant of Significant Accounting Policies | 2. Summary of Significant Accounting Policies Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the combined and consolidated financial statements and accompanying notes. Actual amounts could differ from these estimates. Revenue Recognition The Partnership sells coke as well as steam and electricity and also provides mixing and handling services of coal and other aggregates. Revenues related to the sale of products are recognized when title passes, generally when products are shipped or delivered in accordance with the terms of the respective sales agreements. Service revenues are recognized when services are provided as defined by customer contracts. Revenues are not recognized until sales prices are fixed or determinable and collectability is reasonably assured. Substantially all of the coke produced by the Partnership is sold pursuant to long-term contracts with its customers. The Partnership evaluates each of its contracts to determine whether the arrangement contains a lease under the applicable accounting standards. If the specific facts and circumstances indicate that it is remote that parties other than the contracted customer will take more than a minor amount of the coke that will be produced by the property, plant and equipment during the term of the coke supply agreement, and the price that the customer is paying for the coke is neither contractually fixed per unit nor equal to the current market price per unit at the time of delivery, then the long-term contract is deemed to contain a lease. The lease component of the price of coke represents the rental payment for the use of the property, plant and equipment, and all such payments are accounted for as contingent rentals as they are only earned by the Partnership when the coke is delivered and title passes to the customer. The total amount of revenue recognized by the Partnership for these contingent rentals represents less than 10 percent of sales and other operating revenues for each of the years ended December 31, 2017 , 2016 and 2015 . The Partnership receives payment for shortfall obligations on certain logistics take-or-pay contracts. The payments in excess of service performed is recorded in deferred revenue on the Consolidated Balance Sheets. Deferred revenue on take-or-pay contracts is generally billed quarterly and recognized as income at the earlier of when service is provided or annually based on the terms of the contract. Cash Equivalents The Partnership considers all highly liquid investments with a remaining maturity of three months or less at the time of purchase to be cash equivalents. These cash equivalents consist principally of money market investments. Inventories Inventories are valued at the lower of cost or net realizable value. Cost is determined using the first-in, first-out method, except for the Partnership’s materials and supplies inventory, which are determined using the average-cost method. The Partnership utilizes the selling prices under its long-term coke supply contracts to record lower of cost or net realizable value inventory adjustments. Properties, Plants and Equipment Plants and equipment are depreciated on a straight-line basis over their estimated useful lives. Coke and energy plant, machinery and equipment are generally depreciated over 25 to 30 years . Logistics plant and equipment are generally depreciated over 15 to 35 years . Depreciation and amortization is excluded from cost of products sold and operating expenses and is presented separately in the Combined and Consolidated Statements of Operations. Gains and losses on the disposal or retirement of fixed assets are reflected in earnings when the assets are sold or retired. Amounts incurred that extend an asset’s useful life, increase its productivity or add production capacity are capitalized. The Partnership capitalized interest of $1.1 million , $5.0 million and $3.7 million in 2017, 2016 and 2015 , respectively. Direct costs, such as outside labor, materials, internal payroll and benefits costs, incurred during capital projects are capitalized; indirect costs are not capitalized. Normal repairs and maintenance costs are expensed as incurred. Impairment of Long-Lived Assets Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. A long-lived asset, or group of assets, is considered to be impaired when the undiscounted net cash flows expected to be generated by the asset are less than its carrying amount. Such estimated future cash flows are highly subjective and are based on numerous assumptions about future operations and market conditions. The impairment recognized is the amount by which the carrying amount exceeds the fair market value of the impaired asset, or group of assets. It is also difficult to precisely estimate fair market value because quoted market prices for our long-lived assets may not be readily available. Therefore, fair market value is generally based on the present values of estimated future cash flows using discount rates commensurate with the risks associated with the assets being reviewed for impairment. We have had no significant asset impairments during the years ended December 31, 2017 , 2016 and 2015 . Goodwill and Other Intangibles Goodwill, which represents the excess of the purchase price over the fair value of net assets acquired, is tested for impairment as of October 1 of each year, or when events occur or circumstances change that would, more likely than not, reduce the fair value of a reporting unit to below its carrying value. The Partnership performs its annual goodwill impairment test by comparing the fair value of the reporting unit with its carrying amount. The Partnership would recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value. Intangible assets are primarily comprised of permits, customer contracts and customer relationships. Intangible assets are amortized over their useful lives in a manner that reflects the pattern in which the economic benefit of the intangible asset is consumed. Intangible assets are assessed for impairment when a triggering event occurs. There were no impairments of goodwill or other intangible assets during the periods presented. See Note 10 for further discussion on the Logistics goodwill impairment test. Asset Retirement Obligations The fair value of a liability for an asset retirement obligation is recognized in the period in which it is incurred if a reasonable estimate of fair value can be made. The associated asset retirement costs are capitalized as part of the carrying amount of the asset and depreciated over its remaining estimated useful life. At December 31, 2017 and 2016 , Granite City had asset retirement obligations of $6.5 million and $6.1 million , respectively, primarily related to costs associated with restoring land to its original state, which are included in other deferred credits and liabilities on the Consolidated Balance Sheets. Shipping and Handling Costs Shipping and handling costs are included in cost of products sold and operating expenses and are generally passed through to our customers. Income Taxes Deferred tax asset and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those differences are projected to be recovered or settled. See Note 7 for discussion of the impacts of the Tax Cuts and Jobs Act (“Tax Legislation”), which was enacted on December 22, 2017. The Partnership recognizes uncertain tax positions in its financial statements when minimum recognition threshold and measurement attributes are met in accordance with current accounting guidance. There were no uncertain tax positions at December 31, 2017 , and 2016 . See Note 7 . Fair Value Measurements The Partnership determines fair value 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 the measurement date. As required, the Partnership utilizes valuation techniques that maximize the use of observable inputs (levels 1 and 2) and minimize the use of unobservable inputs (level 3) within the fair value hierarchy included in current accounting guidance. Assets and liabilities are classified within the fair value hierarchy based on the lowest level (least observable) input that is significant to the measurement in its entirety. See Note 15 . Recently Issued Pronouncements In May 2014, Financial Accounting Standards Board ("FASB") issued ASU 2014-09, “Revenue from Contracts with Customers (Topic 606),” which supersedes the revenue recognition requirements in “Revenue Recognition (Topic 605),” and requires entities to recognize revenue to depict the transfer of 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. Subsequently, the FASB has issued various ASUs to provide further clarification around certain aspects of ASC 606. This standard will be effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period, and early adoption was permitted on a limited basis. We have substantially completed our analysis of the new standard and do not expect a material change in our revenue recognition model on an annual basis. Deferred revenue at CMT may be recognized on a more accelerated basis during quarterly periods within the year based on facts and circumstances considered at each quarter under the new guidance. The Partnership will adopt this standard on January 1, 2018 using the modified retrospective method. In February 2016, the FASB issued ASU 2016-02, "Leases (Topic 842)." ASU 2016-02 requires lessees to recognize assets and liabilities on the balance sheet for the rights and obligations created by all leases with terms of more than 12 months. It is effective for annual and interim periods in fiscal years beginning after December 15, 2018, with early adoption permitted. A multi-disciplined implementation team has gained an understanding of the accounting and disclosure provisions of the standard and is in the process of analyzing the impacts to our business, including the development of new accounting processes to account for our leases and support the required disclosures. While we are still evaluating the impact of adopting this standard, we expect that upon adoption the right-of-use assets and lease liabilities, such as various plant equipment rentals and the lease of our corporate office space, will increase the reported assets and liabilities on our Consolidated Balance Sheets. We are currently evaluating technology tools to assist with the accounting and reporting requirements of this standard. The Partnership expects to adopt this standard on January 1, 2019 and is currently evaluating our transition method options. Labor Concentrations We are managed and operated by the officers of our general partner. Our operating personnel are employees of our operating subsidiaries. Our operating subsidiaries had approximately 565 employees at December 31, 2017. Approximately 41 percent of our operating subsidiaries' employees are represented by the United Steelworkers union. Additionally, approximately 4 percent are represented by the International Union of Operating Engineers. In 2017, we reached a new three-year agreement for our Granite City location, which will expire on August 31, 2020. |

Acquisitions | 3. Acquisitions Convent Marine Terminal Acquisition On August 12, 2015 , the Partnership completed the acquisition of a 100 percent ownership interest in Raven Energy LLC, which owns Convent Marine Terminal ("CMT"), for a total transaction value of $403.1 million . The transaction value included $191.7 million in cash paid, $75.0 million of common units issued to The Cline Group, $114.9 million of debt assumed and $21.5 million of cash withheld to fund capital expenditures. The results of CMT have been included in the combined and consolidated financial statements since the date of acquisition and are included in the Logistics segment. CMT contributed revenues of $71.1 million , $62.7 million and $28.6 million and operating income of $42.3 million , $46.5 million and $18.4 million during 2017 , 2016 and 2015, respectively. The following combined and consolidated results of operations were prepared using historical financial information of CMT and assumes that the acquisition of CMT occurred on January 1, 2015 : Years Ended December 31, 2017 2016 2015 (Audited) (Unaudited pro forma) (Dollars in millions) Sales and other operating revenue $ 845.6 $ 779.7 $ 871.2 Net income $ (17.5 ) $ 121.4 $ 91.6 Net income per common unit (basic and diluted) $ (0.54 ) $ 2.07 $ 1.90 Net income per subordinated unit (basic and diluted) $ — $ — $ 1.70 The unaudited pro forma combined results of operations reflect historical results adjusted for interest expense, depreciation adjustments based on the fair value of acquired property, plant and equipment, amortization of acquired identifiable intangible assets, and income tax expense. The pro forma combined results do not include acquisition costs or new contracts. The unaudited pro forma combined and consolidated financial statements are presented for informational purposes only and do not necessarily reflect future results given the timing of new customer contracts, revenue recognition related to take-or-pay shortfalls, and other effects of integration, nor do they purport to be indicative of the results of operations that actually would have resulted had the acquisition of CMT occurred on January 1, 2015 or future results. Granite City Dropdown On January 13, 2015, the Partnership acquired a 75 percent interest in SunCoke's Granite City cokemaking facility for a total transaction value of $244.4 million . The transaction value included $148.3 million of debt and other liabilities assumed, $50.1 million of common units issued to SunCoke, $1.0 million of general partner interest issued to the general partner and $45.0 million of cash withheld to pre-fund an environmental remediation project at Granite City. The Partnership accounted for the Granite City Dropdown as an equity transaction, with SunCoke's interest in Granite City reflected in parent net equity until the date of the transaction. On the date of the Granite City Dropdown, the historical cost of the Granite City assets acquired of $203.6 million was allocated to the general partner and limited partners based on their ownership interest in the Partnership immediately following the transaction, and $67.9 million was allocated to noncontrolling interest for the 25 percent of Granite City retained by SunCoke. The net impact on Partnership equity of the $203.6 million book value acquired, net of the transaction value recorded through equity of $188.5 million was $15.1 million . On August 12, 2015 , the Partnership acquired an additional 23 percent interest in SunCoke's Granite City cokemaking facility for a total transaction value of $65.2 million . The transaction value included $46.9 million of debt and other liabilities assumed, $17.9 million of common units issued to SunCoke and $0.4 million of general partner interest issued to the general partner. The Partnership accounted for the Granite City Supplemental Dropdown as an equity transaction. On the date of the Granite City Supplemental Dropdown, the historical cost of the Granite City assets acquired was $66.0 million , which was allocated to the general partner and limited partners based on their ownership of the Partnership immediately following the transaction with an equal and offsetting decrease in noncontrolling interest. The net impact on Partnership equity of the $66.0 million book value acquired, net of the transaction value recorded through equity of $62.3 million was $3.7 million . Subsequent to the Granite City Supplemental Dropdown and the acquisition of CMT, SunCoke, through a subsidiary, owned a 53.4 percent partnership interest in us and all of our IDRs and indirectly owned and controlled our general partner, which holds a 2 percent general partner interest in us. The table below summarizes the effects of the changes in the Partnership’s ownership interest in Granite City on the Partnership’s equity: Year Ended December 31, 2015 (Dollars in millions) Net income attributable to SunCoke Energy Partners, L.P. $ 85.4 Change in SunCoke Energy Partners, L.P. partnership equity for the purchase of 75.0 percent interest in Granite City 15.1 Change in SunCoke Energy Partners, L.P. partnership equity for the purchase of an additional 23.0 percent interest in Granite City 3.7 Change from net income attributable to SunCoke Energy Partners, L.P. and transfers to noncontrolling interest $ 104.2 |

Related Party Transactions [Abstract] | |
Related Party Transactions | 4. Related Party Transactions Transactions with Affiliate Logistics provides coal handling and mixing services to certain SunCoke cokemaking operations. During 2017 , 2016 , and 2015 , Logistics recorded $17.3 million , $17.1 million and $13.9 million , respectively, in revenues derived from services provided to SunCoke’s cokemaking operations. The Partnership also purchased coal and other services from SunCoke and its affiliates totaling $4.8 million and $6.8 million during 2016 , and 2015 , respectively . Allocated Expenses We were allocated expenses of $27.6 million , $27.9 million and $26.4 million in 2017 , 2016 and 2015 , respectively, for services provided to us by SunCoke. SunCoke centrally provides engineering, operations, procurement and information technology support to its facilities. In addition, allocated costs include legal, accounting, tax, treasury, insurance, employee benefit costs, communications and human resources. Corporate allocations are recorded based upon the omnibus agreement under which SunCoke will continue to provide us with certain support services. SunCoke will charge us for all direct costs and expenses incurred on our behalf and a fee associated with support services provided to our operations . In the first half of 2016 , SunCoke took certain actions to support the Partnership's strategy to de-lever its balance sheet and maintain a solid liquidity position. During the first quarter of 2016 , SunCoke provided a "reimbursement holiday" on the $7.0 million of corporate costs allocated to the Partnership and also returned its $1.4 million IDR cash distribution to the Partnership ("IDR giveback"), resulting in capital contributions of $8.4 million . During the second quarter of 2016 , SunCoke provided the Partnership with deferred payment terms until April 2017 on the reimbursement of the $7.0 million of allocated corporate costs to the Partnership and the $1.4 million IDR cash distribution, resulting in an outstanding payable to SunCoke of $8.4 million included in payable to affiliate, net on the Consolidated Balance Sheets as of December 31, 2016. During 2017, the Partnership paid the amounts due to SunCoke. Omnibus Agreement In connection with the closing of our initial public offering ("IPO"), we entered into an omnibus agreement with SunCoke and our general partner that addresses certain aspects of our relationship with them, including: Business Opportunities. We have preferential rights to invest in, acquire and construct cokemaking facilities in the U.S. and Canada. SunCoke has preferential rights to all other business opportunities. Environmental Indemnity. SunCoke will indemnify us to the full extent of any remediation at the Haverhill, Middletown and Granite City cokemaking facilities arising from any known environmental matter discovered and identified as requiring remediation prior to the closing of the IPO and the Granite City Dropdown, respectively. In connection with the IPO and subsequent asset dropdowns, SunCoke has contributed $119 million in partial satisfaction of this obligation and will reimburse us for additional spending in excess of $119 million as required for such known remediation obligations. Other Indemnification. SunCoke will fully indemnify us with respect to any additional tax liability related to periods prior to or in connection with the closing of the IPO or the Granite City Dropdown to the extent not currently presented on the Consolidated Balance Sheets. Additionally, SunCoke will either cure or fully indemnify us for losses resulting from any material title defects at the properties owned by the entities acquired in connection with the closing of the IPO or the Granite City Dropdown to the extent that those defects interfere with or could reasonably be expected to interfere with the operations of the related cokemaking facilities. We will indemnify SunCoke for events relating to our operations except to the extent that we are entitled to indemnification by SunCoke. License. SunCoke has granted us a royalty-free license to use the name “SunCoke” and related marks. Additionally, SunCoke has granted us a non-exclusive right to use all of SunCoke's current and future cokemaking and related technology. We have not paid and will not pay a separate license fee for the rights we receive under the license. Expenses and Reimbursement. SunCoke will continue to provide us with certain corporate and other services, and we will reimburse SunCoke for all direct costs and expenses incurred on our behalf and a portion of corporate and other costs and expenses attributable to our operations. SunCoke may consider providing additional support to the Partnership in the future by providing a corporate cost reimbursement holiday, whereby the Partnership would not be required to reimburse SunCoke for costs. Additionally, we paid all fees in connection with our senior notes offering and our revolving credit facility and have agreed to pay all additional fees in connection with any future financing arrangement entered into for the purpose of replacing the credit facility or the senior notes. So long as SunCoke controls our general partner, the omnibus agreement will remain in full force and effect unless mutually terminated by the parties. If SunCoke ceases to control our general partner, the omnibus agreement will terminate, but our rights to indemnification and use of SunCoke's existing cokemaking and related technology will survive. The omnibus agreement can be amended by written agreement of all parties to the agreement, but we may not agree to any amendment that would, in the reasonable discretion of our general partner, be adverse in any material respect to the holders of our common units without prior approval of the conflicts committee. |

Customer Concentrations | 5. Customer Concentrations In 2017 , the Partnership sold approximately 2.3 million tons of coke under long-term take-or-pay contracts to its three primary customers: AK Steel Corporation ("AK Steel"), ArcelorMittal USA LLC and/or its affiliates (“AM USA”) and United States Steel Corporation ("U.S. Steel"). The table below shows sales to the Partnership's significant customers for the years ended December 31, 2017, 2016 and 2015: Years ended December 31, 2017 2016 2015 Sales and other operating revenue Percent of Partnership sales and other operating revenue Sales and other operating revenue Percent of Partnership sales and other operating revenue Sales and other operating revenue Percent of Partnership sales and other operating revenue (Dollars in millions) AM USA (1) $ 182.4 21.6 % $ 142.5 18.3 % $ 150.3 17.9 % AK Steel (1) $ 331.3 39.2 % $ 350.0 44.9 % $ 395.4 47.2 % U.S. Steel (2) $ 214.1 25.3 % $ 185.3 23.8 % $ 213.1 25.4 % (1) Represents revenues included in our Domestic Coke segment. (2) Represents revenues included in our Domestic Coke and Logistics segments. Since 2015, AK Steel has kept its Ashland Kentucky Works facility idled and U.S. Steel has kept portions of its Granite City Works facility idled. These temporary idlings do not change any obligations that AK Steel and/or U.S. Steel have under their long-term, take-or-pay contracts with us. The Partnership generally does not require any collateral with respect to its receivables. At December 31, 2017 , the Partnership’s receivables balances were primarily due from AM USA, AK Steel and U.S. Steel. As a result, the Partnership experiences concentrations of credit risk in its receivables with these three customers. These concentrations of credit risk may be affected by changes in economic or other conditions affecting the steel industry. The table below shows receivables due from the Partnership's three significant customers as of December 31, 2017 and 2016 : December 31, 2017 2016 (Dollars in millions) AM USA $ 7.0 $ 7.4 AK Steel $ 13.2 $ 10.7 US Steel $ 5.6 $ 5.7 Our Logistics business provides coal handling and storage services to Murray Energy Corporation, Inc. ("Murray") and Foresight Energy LLC ("Foresight"), who are the two primary customers in the Logistics segment and related parties of The Cline Group, a beneficial owner of the Partnership. Sales to Murray and Foresight accounted for $57.8 million , or 6.8 percent , $53.5 million , or 6.9 percent and $22.0 million , or 2.6 percent of the Partnership's sales and other operating revenue and were recorded in the Logistics segment for the years ended December 31, 2017 , 2016 and 2015 , respectively, representing 51.4 percent , 51.4 percent and 27.1 percent of Logistics revenue, including intersegment sales, in 2017 , 2016 and 2015 , respectively. Receivables from Murray and Foresight were $9.7 million and $8.0 million and were recorded in receivables on the Consolidated Balance Sheets at December 31, 2017 and 2016 , respectively. |

Earnings Per Share [Abstract] | |
Net Income Per Unit and Cash Distribution | 6. Net Income Per Unit and Cash Distribution Cash Distributions The Partnership distributes available cash on or about the first day of each of March, June, September and December to the holders of record of common units on or about the 15th day of each such month. Available cash is generally all cash on hand, less reserves established by the general partner in its discretion. Our general partner has broad discretion to establish cash reserves that it determines are necessary or appropriate for the proper conduct of Partnership’s business. The Partnership intends to make quarterly distributions, to the extent there is sufficient cash from operations after establishment of cash reserves and payment of fees and expenses, including payments to the general partner. Our general partner's board of directors will evaluate the appropriate level of cash distributions on a quarterly basis. There is no guarantee that the Partnership will pay a quarterly distribution on the common units in any quarter. Additionally, the Partnership will be prohibited from making any distributions to unitholders if it would cause an event of default, or an event of default exists, under the credit facility or the senior notes. See Note 12 . In general, the Partnership, pays cash distributions each quarter in the following manner: • first , 98 percent to the holders of common units and 2 percent to our general partner, until each common unit has received the minimum quarterly distribution of $0.412500 plus any arrearages from prior quarters; • second, 98 percent to all unitholders, pro rata, and 2 percent to our general partner, until each unit has received a distribution of $0.474375 . If cash distributions to our unitholders exceed $0.474375 per unit in any quarter, our unitholders and our general partner will receive distributions according to the following percentage allocations: Total Quarterly Distribution Per Unit Amount Marginal Percentage Unitholders General Partner Minimum Quarterly Distribution $0.412500 98 % 2 % First Target Distribution above $0.412500 up to $0.474375 98 % 2 % Second Target Distribution above $0.474375 up to $0.515625 85 % 15 % Third Target Distribution above $0.515625 up to $0.618750 75 % 25 % Thereafter above $0.618750 50 % 50 % Our distributions are declared subsequent to quarter end. The table below represents total cash distributions applicable to the period in which the distributions were earned: Earned in Quarter Ended Total Quarterly Distribution Per Unit Total Cash Distribution, including general partner's IDRs Date of Distribution Unitholders Record Date (Dollars in millions) December 31, 2016 $ 0.5940 $ 29.5 March 1, 2017 February 15, 2017 March 31, 2017 $ 0.5940 $ 29.5 June, 1, 2017 May 15, 2017 June 30, 2017 $ 0.5940 $ 29.5 September 1, 2017 August 15, 2017 September 30, 2017 $ 0.5940 $ 29.5 December 1, 2017 November 15, 2017 December 31, 2017 (1) $ 0.5940 $ 29.5 March 1, 2018 February 15, 2018 (1) On January 22, 2018 , our Board of Directors declared a cash distribution of $0.5940 per unit. The distribution will be paid on March 1, 2018 , to unitholders of record on February 15, 2018 . Allocation of Net Income Our partnership agreement contains provisions for the allocation of net income to the unitholders and the general partner. For purposes of maintaining partner capital accounts, the partnership agreement specifies that items of income and loss shall be allocated among the partners in accordance with their respective percentage interest. Normal allocations according to percentage interests are made after giving effect, if any, to priority income allocations in an amount equal to incentive cash distributions allocated 100 percent to the general partner. Prior to the Granite City Dropdown, the allocation of net income from Granite City’s operations is allocated to the general partner. Upon payment of the cash distribution for the fourth quarter of 2015, the financial requirements for the conversion of all subordinated units were satisfied. As a result, the 15,709,697 subordinated units converted into common units on a one-for-one basis. For purpose of calculating net income per unit, the conversion of the subordinated units is deemed to have occurred on January 1, 2016. The conversion did not impact the amount of the cash distribution paid or the total number of the Partnership's outstanding units representing limited partner interest. The calculation of net income allocated to the general and limited partners was as follows: Years Ended December 31, 2017 2016 2015 (Dollars in millions) Net income attributable to SunCoke Energy Partners L.P./Previous Owners $ (18.1 ) $ 119.1 $ 86.0 Less: Expense allocated to Common - SunCoke (1) — (7.0 ) — Less: Allocation of net income attributable to Predecessors to the general partner — — 0.6 Net income attributable to partners (18.1 ) 126.1 85.4 General partner's incentive distribution rights 7.5 21.0 6.4 Net income attributable to partners, excluding incentive distribution rights (25.6 ) 105.1 79.0 General partner's ownership interest 2.0 % ` 2.0 % 2.0 % General partner's allocated interest in net income (2) (0.4 ) 2.6 1.6 General partner's incentive distribution rights 7.5 21.0 6.4 Net income attributable to Previous Owners — — 0.6 Total general partner's interest in net income $ 7.1 $ 23.6 $ 8.6 Common - public unitholder's interest in net income $ (13.5 ) $ 46.1 $ 34.0 Common - SunCoke interest in net income: Common - SunCoke interest in net income (11.7 ) 56.4 14.9 Expenses allocated to Common - SunCoke (1) — (7.0 ) — Total common - SunCoke interest in net income (11.7 ) 49.4 14.9 Subordinated - SunCoke interest in net income — — 28.5 Total limited partners' interest in net income $ (25.2 ) $ 95.5 $ 77.4 (1) Per the amended partnership agreement, expenses paid on behalf of the Partnership are to be allocated entirely to the partner who paid them. During the first quarter of 2016 , SunCoke paid $7.0 million of allocated corporate costs on behalf of the Partnership and will not seek reimbursement for those costs. See Note 4 . These expenses are recorded as a direct reduction to SunCoke's interest in net income for the year ended December 31, 2016 . (2) Our net income is allocated to the general partner and limited partners in accordance with their respective partnership percentages, after giving effect to priority income allocations for incentive distributions, if any, to our general partner, pursuant to our partnership agreement. The table above represents a simplified presentation of the calculation, and therefore, amounts may not recalculate precisely. Earnings Per Unit Our net income is allocated to the general partner and limited partners in accordance with their respective partnership percentages, after giving effect to priority income allocations for incentive distributions, if any, to our general partner, pursuant to our partnership agreement. Distributions less than or greater than earnings are allocated in accordance with our partnership agreement. Payments made to our unitholders are determined in relation to actual distributions declared and are not based on the net income allocations used in the calculation of net income per unit. In addition to the common and subordinated units, we have also IDRs as participating securities and use the two-class method when calculating the net income per unit applicable to limited partners, which is based on the weighted-average number of common units outstanding during the period. Basic and diluted net income per unit applicable to limited partners are the same because we do not have any potentially dilutive units outstanding. In 2015, the Partnership early adopted ASU 2015-06-Earnings Per Share (Topic 260): Effects on Historical Earnings per Unit of Master Limited Partnership Dropdown Transactions (a consensus of the Emerging Issues Task Force)." Therefore, the Granite City Dropdown does not impact historical earnings per limited partner unit as earnings prior to the dropdown were allocated to our general partner. The calculation of earnings per unit is as follows: Years Ended December 31, 2017 2016 2015 (Dollars in millions, except per unit amounts) Net income attributable to SunCoke Energy Partners L.P./Previous Owner $ (18.1 ) $ 119.1 $ 86.0 Less: Expense allocated to Common - SunCoke (1) — (7.0 ) — Less: Allocation of net income attributable to Previous Owner to the general partner — — 0.6 Net income attributable to all partners (18.1 ) 126.1 85.4 General partner's distributions (including $5.6 million, $5.6 million and $4.7 million of cash incentive distribution rights declared, respectively) 8.0 8.0 7.2 Limited partners' distributions on common units 109.8 109.8 67.7 Limited partners' distributions on subordinated units — — 36.9 Distributions (greater than) less than earnings (135.9 ) 8.3 (26.4 ) General partner's earnings: Distributions (including $5.6 million, $5.6 million and $4.7 million of cash incentive distribution rights declared, respectively) 8.0 8.0 7.2 Allocation of distributions (greater than) less than earnings (0.9 ) 15.6 0.8 Net income attributable to Previous Owner — — 0.6 Total general partner's earnings 7.1 23.6 8.6 Limited partners' earnings on common units: Distributions 109.8 109.8 67.7 Expenses allocated to Common - SunCoke — (7.0 ) — Allocation of distributions (greater than) less than earnings (135.0 ) (7.3 ) (17.3 ) Total limited partners' earnings on common units (25.2 ) 95.5 50.4 Limited partners' earnings on subordinated units: Distributions — — 36.9 Allocation of distributions (greater than) less than earnings — — (9.9 ) Total limited partners' earnings on subordinated units $ — $ — $ 27.0 Weighted average limited partner units outstanding: Common - basic and diluted 46.2 46.2 26.2 Subordinated - basic and diluted — — 15.7 Net income per limited partner unit: Common - basic and diluted $ (0.54 ) $ 2.07 $ 1.92 Subordinated - basic and diluted $ — $ — $ 1.71 (1) Per the amended partnership agreement, expenses paid on behalf of the Partnership are to be allocated entirely to the partner who paid them. During the first quarter of 2016 , SunCoke paid $7.0 million of allocated corporate costs on behalf of the Partnership and will not seek reimbursement for those costs. See Note 4 . These expenses are recorded as a direct reduction to SunCoke's interest in net income for the year ended December 31, 2016 .

During 2015, the Partnership repurchased 856,000 common units, in the open market, for $12.8 million at an average price of $14.91 per unit. As of December 31, 2017 , the Partnership had $37.2 million available under the authorized unit repurchase program. (2) Upon payment of the cash distribution for the fourth quarter of 2015, the financial requirements for the conversion of all subordinated units were satisfied. As a result, the 15,709,697 subordinated units converted into common units on a one-for-one basis. |

Income Taxes | 7. Income Taxes The Partnership is a limited partnership and generally is not subject to federal or state income taxes. In January 2017, the IRS announced its decision to exclude cokemaking as a qualifying income generating activity in its final regulations (the "Final Regulations") issued under section 7704(d)(1)(E) of the Internal Revenue Code relating to the qualifying income exception for publicly traded partnerships. Subsequent to the 10-year transition period, certain cokemaking entities in the Partnership will become taxable as corporations. As part of the Granite City Dropdown in the first quarter of 2015, the Partnership acquired an interest in Gateway Cogeneration Company, LLC, which is subject to income taxes for federal and state purposes. In addition, the Granite City and Middletown operations in the Partnership are subject to state and local income taxes. The components of income tax expense (benefit) are as follows: Years Ended December 31, 2017 2016 2015 (Dollars in millions) Income taxes currently payable: U.S. federal $ 1.7 $ 2.1 $ — U.S. state and local 0.9 — — Total taxes currently payable 2.6 2.1 — Deferred tax expense (benefit): U.S. federal 72.5 (1.1 ) 1.7 U.S. state and local 8.8 1.0 (4.2 ) Total deferred tax expense (benefit) 81.3 (0.1 ) (2.5 ) Total $ 83.9 $ 2.0 $ (2.5 ) The reconciliation of Partnership income tax expense (benefit) at the U.S. statutory rate is as follows: Years Ended December 31, 2017 2016 2015 (Dollars in millions) Income tax expense at U.S. statutory rate of 35 percent $ 23.3 35.0 % $ 43.2 35.0 % $ 31.0 35.0 % (Reduction) increase in income taxes resulting from: Impact of Final Regulations (1) 148.6 223.5 % — — % — — % Impact of Tax Legislation (2) (68.8 ) (103.1 )% — — % — — % Partnership income not subject to tax (21.8 ) (32.8 )% (42.2 ) (34.1 )% (30.2 ) (34.0 )% State and local tax for Middletown and Granite City operations 2.6 3.7 % 1.2 0.9 % (2.3 ) (2.6 )% Other — — % (0.2 ) (0.2 )% (1.0 ) (1.0 )% Total tax provision $ 83.9 126.3 % $ 2.0 1.6 % $ (2.5 ) (2.6 )% (1) As a result of the Final Regulation discussed above, the Partnership recorded deferred income tax expense of $148.6 million related to the future tax obligation expected to be owed for the projected book to tax differences at the end of the 10-year transition period. (2) On December 22, 2017, the Tax Legislation was enacted. The Tax Legislation significantly revises the U.S. corporate income tax structure, including lowering corporate income tax rates. As a result, the Partnership recorded an income tax benefit of $68.8 million for the remeasurement of its U.S. deferred income tax liabilities, reversing a portion of the deferred income tax expense recorded from the Final Regulations in the first quarter of 2017. The tax effects of temporary differences that comprise the net deferred income tax (liability) asset are as follows: December 31, 2017 2016 (Dollars in millions) Deferred tax assets: State and local net operating loss $ — $ 0.5 Other liabilities not yet deductible — 0.1 Total deferred tax assets — 0.6 Less valuation allowance — (0.2 ) Deferred tax asset, net — 0.4 Deferred tax liabilities: Properties, plants and equipment (1) (118.4 ) (37.5 ) Other liabilities (0.8 ) (0.8 ) Total deferred tax liabilities (119.2 ) (38.3 ) Net deferred tax liability $ (119.2 ) $ (37.9 ) (1) The increase in the deferred tax liabilities associated with properties, plants and equipment is a result of the Final Regulations discussed above. The Partnership is currently open to examination by the IRS for the tax years ended December 31, 2014 and forward. State and local income tax returns are generally subject to examination for a period of three years after filing of the respective returns. Pursuant to the omnibus agreement, SunCoke will fully indemnify us with respect to any tax liability arising prior to or in connection with the closing of our IPO. There are no uncertain tax positions recorded at December 31, 2017 or 2016 and there were no interest or penalties recognized related to uncertain tax positions for the years ended December 31, 2017 , 2016 or 2015 . |

Goodwill and Other Intangible Assets | 10. Goodwill and Other Intangible Assets Goodwill allocated to the Partnership's reportable segments as of December 31, 2017 and 2016 and changes in the carrying amount of goodwill during the fiscal years ended December 31, 2016 are shown below. There were no changes in the carrying amount of goodwill during the fiscal year ended December 31, 2017 : Logistics (Dollars in millions) Net balance at December 31, 2015 $ 67.7 Adjustments (1) 5.8 Net balance at December 31, 2016 and 2017 $ 73.5 (1) During 2016, the Partnership recorded an adjustment to correct an error in the acquisition date fair value of the contingent consideration liability, which increased the contingent consideration liability and goodwill balance by $6.4 million . Additionally, a working capital adjustment to the acquisition date fair value of the acquired net assets decreased the amount of the purchase price allocated to goodwill by $0.6 million . The Partnership performed its annual goodwill impairment test as of October 1, 2017, with no indication of impairment. The fair value of the Logistics reporting unit, which was determined based on a discounted cash flow analysis, exceeded carrying value of the reporting unit by approximately 25 percent . A significant portion of our logistics business holds long-term, take-or-pay contracts with Murray and Foresight. Key assumptions in our goodwill impairment test include continued customer performance against long-term, take-or-pay contracts, renewal of future long-term, take-or-pay contracts, incremental merchant business and a 14 percent discount rate representing the estimated weighted average cost of capital for this business line. The use of different assumptions, estimates or judgments, such as the estimated future cash flows of Logistics and the discount rate used to discount such cash flows, could significantly impact the estimated fair value of a reporting unit, and therefore, impact the excess fair value above carrying value of the reporting unit. A 100 basis point change in the discount rate would not have reduced the fair value of the reporting unit below its carrying value. To the extent changes in factors or circumstances occur that impact our future cash flow projections, such as a loss of either Murray or Foresight as customers, significant reductions in volume or pricing beyond our existing contract term or lower incremental merchant business, future assessments of goodwill and intangible assets may result in material impairment charges. The following table summarizes the components of gross and net intangible asset balances as of December 31, 2017 and December 31, 2016 (dollars in millions): December 31, 2017 December 31, 2016 Weighted - Average Remaining Amortization Years Gross Carrying Amount Accumulated Amortization Net Gross Carrying Amount Accumulated Amortization Net (Dollars in millions) Customer contracts 5 $ 24.0 $ 7.8 $ 16.2 $ 24.0 $ 4.5 $ 19.5 Customer relationships 14 28.7 5.7 23.0 28.7 3.8 24.9 Permits 25 139.0 12.2 126.8 139.0 7.1 131.9 Trade name 1 1.2 1.0 0.2 1.2 0.8 0.4 Total $ 192.9 $ 26.7 $ 166.2 $ 192.9 $ 16.2 $ 176.7 The permits above represent the environmental and operational permits required to operate a coal export terminal in accordance with the United States Environmental Protection Agency and other regulatory bodies. Intangible assets are amortized over their useful lives in a manner that reflects the pattern in which the economic benefit of the asset is consumed. The permits’ useful lives were estimated to be 27 years at acquisition based on the expected useful life of the significant operating equipment at the facility. We have historical experience of renewing and extending similar arrangements at our other facilities and intend to continue to renew our permits as they come up for renewal for the foreseeable future. The permits were renewed regularly prior to our acquisition of CMT. These permits have an average remaining renewal term of approximately 3.4 years. Total amortization expense for intangible assets subject to amortization was $10.5 million , $10.7 million and $4.5 million for the years ended December 31, 2017 , 2016 and 2015 , respectively. Based on the carrying value of finite-lived intangible assets as of December 31, 2017 , we estimate amortization expense for each of the next five years as follows: (Dollars in Millions) 2017 $ 10.4 2018 10.3 2019 10.3 2020 10.3 2021 10.2 Thereafter 114.7 Total $ 166.2 |

Retirement and Other Post-Employment Benefits Plans | 11. Retirement and Other Post-Employment Benefits Plans Certain employees of the Partnership's operating subsidiaries participate in defined contribution and postretirement health care and life insurance plans sponsored by SunCoke. The Partnership’s contributions to the defined contribution plans, which are principally based on its allocable portion of SunCoke’s pretax income and the aggregate compensation levels of participating employees, are charged against income as incurred. These charges amounted to $3.9 million , $3.4 million and $3.5 million in 2017 , 2016 and 2015 , respectively, and are reflected in cost of products sold and operating expenses in the Combined and Consolidated Statements of Operations. The postretirement benefit plans are unfunded and the costs are borne by the Partnership. The expense allocated to the Partnership for other postretirement benefit plans was immaterial for all periods presented. These defined contribution, postretirement health care and life insurance plans have been accounted for in the combined and consolidated financial statements as multi-employer plans. |

The Partnership received proceeds of $693.7 million , net of a net discount of $6.3 million during 2017. The Partnership incurred debt issuance costs related to this transaction of $12.9 million . The 2025 Partnership Notes are the senior unsecured obligations of the Partnership, and are guaranteed on a senior unsecured basis by each of the Partnership’s existing and certain future subsidiaries. Interest on the 2025 Partnership Notes is payable semi-annually in cash in arrears on June 15 and December 15 of each year, which commenced on December 15, 2017. The Partnership may redeem some or all of the 2025 Partnership Notes at any time on or after June 15, 2020 at specified redemption prices plus accrued and unpaid interest, if any, to the redemption date. Before June 15, 2020, and following certain equity offerings, the Partnership also may redeem up to 35 percent of the 2025 Partnership Notes at a price equal to 107.5 percent of the principal amount, plus accrued and unpaid interest, if any, to the redemption date. In addition, at any time prior to June 15, 2020, the Partnership may redeem some or all of the 2025 Partnership Notes at a price equal to 100 percent of the principal amount, plus accrued and unpaid interest, if any, to the redemption date, plus a “make-whole” premium. The Partnership is obligated to offer to purchase all or a portion of the 2025 Partnership Notes at a price of (a) 101 percent of their principal amount, together with accrued and unpaid interest, if any, to the date of purchase, upon the occurrence of certain change of control events and (b) 100 percent of their principal amount, together with accrued and unpaid interest, if any, to the date of purchase, upon the occurrence of certain asset dispositions. These restrictions and prohibitions are subject to certain qualifications and exceptions set forth in the Indenture, including without limitation, reinvestment rights with respect to the proceeds of asset dispositions. The 2025 Partnership Notes contains covenants that, among other things, limit the Partnership’s ability and the ability of certain of the Partnership’s subsidiaries to (i) incur indebtedness, (ii) pay dividends or make other distributions, (ii) prepay, redeem or repurchase certain subordinated debt, (iv) make loans and investments, (v) sell assets, (vi) incur liens, (vii) enter into transactions with affiliates, (viii) enter into agreements restricting the ability of subsidiaries to pay dividends and (ix) consolidate or merge. Purchase, Redemption and Repayment of Partnership Debt During 2017, the Partnership used the proceeds from the issuance of the 2025 Partnership Notes to purchase and redeem all of its 2020 Partnership Notes, including principal of $463.0 million and a premium of $18.7 million , repay the $50.0 million outstanding on the Partnership Term Loan, repay the $112.6 million outstanding on the Partnership's Promissory Note and reduce the Partnership Revolver outstanding balance by $42.0 million . As a result of the debt extinguishment, the Partnership recorded a loss on extinguishment of debt on the Consolidated Statement of Operations of $19.2 million , which included the premium paid and a write-off of unamortized debt issuance costs of $7.1 million partly offset by a write-off of unamortized premiums of $6.6 million . Partnership Revolver The proceeds of any borrowings made under the Partnership Revolver can be used to finance working capital needs, acquisitions, capital expenditures and for other general corporate purposes. The Partnership Revolver provides total aggregate commitments from lenders of $285.0 million and up to $200.0 million uncommitted incremental revolving capacity. The obligations under the Partnership Revolver are guaranteed by the Partnership’s subsidiaries and secured by liens on substantially all of the Partnership’s and the guarantors’ assets. In May 2017, the Partnership amended and restated the Partnership Revolver, which increased the Partnership's capacity from $250.0 million to $285.0 million and extended the maturity May 2019 to May 2022. In connection with the amendments to the Partnership Revolver, the Partnership incurred debt issuance costs of $3.0 million and recorded a loss on extinguishment of debt on the Consolidated Statement of Operations of $0.8 million , representing a write-off of unamortized debt issuance costs, during 2017. As of December 31, 2017, the Partnership had $1.9 million of letters of credit outstanding and an outstanding balance of $130.0 million , leaving $153.1 million available. Commitment fees are based on the unused portion of the Partnership Revolver at a rate of 0.4 percent . The Partnership Revolver borrowings bear interest at a variable rate of LIBOR plus 250 basis points or an alternative base rate plus 150 basis points. The spread is subject to change based on the Partnership's consolidated leverage ratio, as defined in the credit agreement. The weighted-average interest rate for borrowings under the Partnership Revolver was 3.8 percent , 3.3 percent and 2.9 percent during 2017, 2016 and 2015, respectively Partnership Financing Obligation In 2016, the Partnership entered into a sale-leaseback arrangement of certain coke and logistics equipment. The leaseback agreement has an initial lease period of 60 months, with an effective interest rate of 5.82 percent and an early buyout option after 48 months to purchase the equipment at 34.5 percent of the original lease equipment cost. The arrangement is accounted for as a financing transaction, resulting in a financing obligation on the Consolidated Balance Sheets. The financing obligation is guaranteed by the Partnership. Covenants Under the terms of the Partnership's credit agreement, the Partnership is subject to a maximum consolidated leverage ratio of 4.5 : 1.0 prior to June 30, 2020 and 4.0 : 1.0 after June 30, 2020 and a minimum consolidated interest coverage ratio of 2.5 : 1.0 . The Partnership's credit agreement contains other covenants and events of default that are customary for similar agreements and may limit our ability to take various actions including our ability to pay a dividend or repurchase our stock. If we fail to perform our obligations under these and other covenants, the lenders' credit commitment could be terminated and any outstanding borrowings, together with accrued interest, under the Partnership Revolver could be declared immediately due and payable. The Partnership have a cross default provision that applies to our indebtedness having a principal amount in excess of $35.0 million . As of December 31, 2017 , the Partnership were in compliance with all debt covenants. We do not anticipate violation of these covenants nor do we anticipate that any of these covenants will restrict our operations or our ability to obtain additional financing.

Commitments and Contingent Liabilities | 13. Commitments and Contingent Liabilities Lease Obligations The Partnership, as lessee, has noncancelable operating leases for land, office space, equipment and railcars. Total rental expense was $4.1 million , $4.9 million and $4.6 million in 2017 , 2016 and 2015 , respectively. The aggregate amount of future minimum annual rentals applicable to noncancelable operating leases is as follows: Minimum Year ending December 31: (Dollars in millions) 2018 $ 1.8 2019 1.5 2020 0.4 2021 — 2022 — 2023-Thereafter — Total $ 3.7 Legal Matters The United States Environmental Protection Agency (the "EPA") issued Notices of Violations (“NOVs”) for the Haverhill and Granite City cokemaking facilities which stemmed from alleged violations of air operating permits for these facilities. We are working in a cooperative manner with the EPA, the Ohio Environmental Protection Agency and the Illinois Environmental Protection Agency to address the allegations, and have entered into a consent degree in federal district court with these parties. The consent decree includes a $2.2 million civil penalty payment that was paid by SunCoke in 2014, as well as capital projects underway to improve the reliability of the energy recovery systems and enhance environmental performance at the Haverhill and Granite City cokemaking facilities. An amendment was lodged in federal court in February 2018 and is undergoing review. The amendment provides the Haverhill and Granite City facilities with additional time to perform necessary maintenance on the flue gas desulfurization systems without exceeding consent decree limits. The emissions associated with this maintenance will be mitigated in accordance with the amendment, and there are no civil penalty payments. We retained an aggregate of $119 million in proceeds from our IPO and subsequent dropdowns to comply with the expected terms of a consent decree at the Haverhill and Granite City cokemaking operations. SunCoke and the Partnership anticipate spending approximately $145 million to comply with these environmental remediation projects. Pursuant to the omnibus agreement, any amounts that we spend on these projects in excess of the $119 million will be reimbursed by SunCoke. Prior to our formation, SunCoke spent approximately $7 million related to these projects. The Partnership has spent approximately $104 million to date and expects to spend the remaining capital through the first quarter of 2019. SunCoke will reimburse the Partnership approximately $20 million for the estimated additional spending beyond what has previously been funded. The Partnership is a party to certain other pending and threatened claims, including matters related to commercial and tax disputes, product liability, employment claims, personal injury claims, premises-liability claims, allegations of exposures to toxic substances and general environmental claims. Although the ultimate outcome of these claims cannot be ascertained at this time, it is reasonably possible that some portion of these claims could be resolved unfavorably to the Partnership. Management of the Partnership believes that any liability which may arise from claims would not have a material adverse impact on our combined and consolidated financial statements. |

Fair Value Measurements

Fair Value Disclosures [Abstract] | |
Fair Value Measurements | 15. Fair Value Measurements The Partnership measures certain financial and non-financial assets and liabilities at fair value on a recurring basis. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in the principal or most advantageous market in an orderly transaction between market participants on the measurement date. Fair value disclosures are reflected in a three-level hierarchy, maximizing the use of observable inputs and minimizing the use of unobservable inputs. The valuation hierarchy is based upon the transparency of inputs to the valuation of an asset or liability on the measurement date. The three levels are defined as follows: • Level 1—inputs to the valuation methodology are quoted prices (unadjusted) for an identical asset or liability in an active market. • Level 2—inputs to the valuation methodology include quoted prices for a similar asset or liability in an active market or model-derived valuations in which all significant inputs are observable for substantially the full term of the asset or liability. • Level 3—inputs to the valuation methodology are unobservable and significant to the fair value measurement of the asset or liability. Financial Assets and Liabilities Measured at Fair Value on a Recurring Basis Certain assets and liabilities are measured at fair value on a recurring basis. The Partnership’s cash equivalents are measured at fair value based on quoted prices in active markets for identical assets. These inputs are classified as Level 1 within the valuation hierarchy. The Partnership did not have material cash equivalents at December 31, 2017 or 2016 . Non-Financial Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis Certain assets and liabilities are measured at fair value on a nonrecurring basis; that is, the assets and liabilities are not measured at fair value on an ongoing basis, but are subject to fair value adjustments in certain circumstances (e.g., when there is evidence of impairment). At December 31, 2017 , no material fair value adjustments or fair value measurements were required for these non-financial assets or liabilities. Convent Marine Terminal Contingent Consideration In connection with the CMT acquisition, the Partnership entered into a contingent consideration arrangement that requires the Partnership to make future payments to The Cline Group based on future volume over a specified threshold, price, and contract renewals. The fair value of the contingent consideration was estimated based on a probability-weighted analysis using significant inputs that are not observable in the market, or Level 3 inputs. Key assumptions included probability adjusted levels of coal handling services provided by CMT, anticipated price per ton on future sales and probability of contract renewal, including length of future contracts, volume commitment, and anticipated price per ton. The fair value of the contingent consideration at December 31, 2017 and 2016 was $2.5 million and $4.2 million , respectively, and was included in other deferred charges and liabilities on the Consolidated Balance Sheets. During 2017, as a result of adverse mining conditions faced by one of our thermal coal customers, the Partnership lowered CMT's throughput volume projection, which reduced the Partnership's contingent consideration liability balance by $1.7 million . The decrease in fair value was recorded as a reduction to costs of products sold and operating expenses on the Combined and Consolidated Statements of Operations during 2017. Throughput volumes at CMT in 2017 were consistent with projections and higher than 2016 levels, but still significantly below levels that would trigger contingent consideration payments. During March 2016, as part of developing commercial activities subsequent to the acquisition, the Partnership and The Cline Group signed an amended agreement, which modified the contingent consideration terms by increasing the volume threshold required for the Partnership to make payments to The Cline Group in exchange for future pricing modifications. The increase in the volume threshold reduced the fair value of the contingent consideration liability by $3.7 million , which was recorded as a reduction to cost of products sold and operating expense on the Consolidated Statement of Operations. During the second half of 2016, the Partnership lowered CMT’s throughput volume projections in future periods due to declining coal prices which were expected to reduce export volume through CMT. These updated volume projections resulted in a net decrease to the contingent consideration liability, decreasing cost of products sold and operating expenses on the Combined and Consolidated Statements of Operations by $6.4 million during the year ended December 31, 2016. During 2016, the Partnership also recorded an adjustment to correct an error in the acquisition date fair value of the contingent consideration liability, which increased the contingent consideration liability and goodwill balance by $6.4 million . Certain Financial Assets and Liabilities not Measured at Fair Value At December 31, 2017 and 2016 , the estimated fair value of the Partnership’s long-term debt was estimated to be $875.0 million and $810.4 million , respectively, compared to a carrying amount of $842.7 million and $813.4 million , respectively. The fair value was estimated by management based upon estimates of debt pricing provided by financial institutions and are considered Level 2 inputs. |

Segment Reporting [Abstract] | |
Business Segment Information | 16. Business Segment Information The Partnership derives its revenues from the Domestic Coke and Logistics reportable segments. Domestic Coke operations are comprised of the Haverhill and Middletown cokemaking facilities located in Ohio and the Granite City cokemaking facility located in Illinois. These facilities use similar production processes to produce coke and to recover waste heat that is converted to steam or electricity. Steam is provided to customers pursuant to steam supply and purchase agreements. Electricity is sold into the regional power market or to AK Steel pursuant to energy sales agreements. Coke sales at the Partnership's cokemaking facilities are made pursuant to long-term, take-or-pay agreements with AM USA, AK Steel and U.S. Steel. Each of the coke sales agreements contain pass-through provisions for costs incurred in the cokemaking process, including coal procurement costs (subject to meeting contractual coal-to-coke yields), operating and maintenance expenses, costs related to the transportation of coke to the customers, taxes (other than income taxes) and costs associated with changes in regulation, in addition to containing a fixed fee. Logistics operations are comprised of CMT located in Louisiana, Lake Terminal located in Indiana and KRT located in West Virginia. Our Logistics operations have a collective capacity to mix and transload approximately 40 million tons of materials annually and provides handling and/or mixing services to its customers, which include our own cokemaking facilities and other SunCoke cokemaking facilities. Materials handling and mixing results are presented in the Logistics segment. Corporate and other expenses that can be identified with a segment have been included in determining segment results. The remainder is included in Corporate and Other. Segment assets are those assets that are utilized within a specific segment. The following table includes Adjusted EBITDA, which is the measure of segment profit or loss and liquidity reported to the chief operating decision maker for purposes of allocating resources to the segments and assessing their performance: Years Ended December 31, 2017 2016 2015 (Dollars in millions) Sales and other operating revenue: Domestic Coke $ 739.7 $ 681.8 $ 763.8 Logistics 105.9 97.9 74.7 Logistics intersegment sales 6.5 6.1 6.5 Elimination of intersegment sales (6.5 ) (6.1 ) (6.5 ) Total sales and other operating revenue $ 845.6 $ 779.7 $ 838.5 Adjusted EBITDA: Domestic Coke $ 170.3 $ 167.0 $ 177.1 Logistics 69.7 63.2 38.0 Corporate and Other (15.3 ) (17.2 ) (13.8 ) Total Adjusted EBITDA $ 224.7 $ 213.0 $ 201.3 Depreciation and amortization expense: Domestic Coke $ 59.9 $ 53.4 $ 53.4 Logistics 23.7 24.3 14.0 Total depreciation and amortization expense $ 83.6 $ 77.7 $ 67.4 Capital expenditures: Domestic Coke $ 35.0 $ 22.1 $ 36.3 Logistics 4.0 15.0 6.0 Total capital expenditures $ 39.0 $ 37.1 $ 42.3 The following table sets forth the Partnership's segment assets: December 31, 2017 2016 (Dollars in millions) Segment assets: Domestic Coke $ 1,151.4 $ 1,184.2 Logistics 489.8 510.6 Corporate and Other 0.2 1.2 Total Assets $ 1,641.4 $ 1,696.0 The following table sets forth the Partnership’s total sales and other operating revenue by product or service: Years Ended December 31, 2017 2016 2015 (Dollars in millions) Sales and other operating revenue: Cokemaking revenues $ 686.9 $ 623.6 $ 702.8 Energy revenues 52.7 53.7 61.0 Logistics revenues 102.6 96.3 72.7 Other revenues 3.4 6.1 2.0 Total revenues $ 845.6 $ 779.7 $ 838.5 The Partnership evaluates the performance of its segments based on segment Adjusted EBITDA, which is defined as earnings before interest, (gain) loss on extinguishment of debt, taxes, depreciation and amortization ("EBITDA"), adjusted for sales discounts, changes to our contingent consideration liability related to our acquisition of CMT and the expiration of certain acquired contractual obligations. Adjusted EBITDA does not represent and should not be considered an alternative to net income or operating income under GAAP and may not be comparable to other similarly titled measures in other businesses. Management believes Adjusted EBITDA is an important measure of the operating performance and liquidity of the Partnership's net assets and its ability to incur and service debt, fund capital expenditures and make distributions. Adjusted EBITDA provides useful information to investors because it highlights trends in our business that may not otherwise be apparent when relying solely on GAAP measures and because it eliminates items that have less bearing on our operating performance and liquidity. EBITDA and Adjusted EBITDA are not measures calculated in accordance with GAAP, and they should not be considered an alternative to net income, operating cash flow or any other measure of financial performance presented in accordance with GAAP. Set forth below is additional discussion of the limitations of Adjusted EBITDA as an analytical tool. Limitations. Other companies may calculate Adjusted EBITDA differently than we do, limiting its usefulness as a comparative measure. Adjusted EBITDA also has limitations as an analytical tool and should not be considered in isolation or as a substitute for an analysis of our results as reported under GAAP. Some of these limitations include that Adjusted EBITDA : • does not reflect our cash expenditures, or future requirements, for capital expenditures or contractual commitments ; • does not reflect items such as depreciation and amortization; • does not reflect changes in, or cash requirements for, working capital needs; • does not reflect our interest expense, or the cash requirements necessary to service interest on or principal payments of our debt; • does not reflect certain other non-cash income and expenses; • excludes income taxes that may represent a reduction in available cash; and • includes net income attributable to noncontrolling interests. Below are reconciliations of Adjusted EBITDA from net (loss) income and net cash provided by operating activities, which are its most directly comparable financial measures calculated and presented in accordance with GAAP: Years Ended December 31, 2017 2016 2015 (Dollars in millions) Net (loss) income $ (17.5 ) $ 121.4 $ 92.2 Add: Depreciation and amortization expense 83.6 77.7 67.4 Interest expense, net 56.4 47.7 48.2 Loss (gain) on extinguishment of debt 20.0 (25.0 ) (0.7 ) Income tax expense (benefit) 83.9 2.0 (2.5 ) Contingent consideration adjustments (1) (1.7 ) (10.1 ) — Non-cash reversal of acquired contractual obligations (2) — (0.7 ) (3.3 ) Adjusted EBITDA (3) $ 224.7 $ 213.0 $ 201.3 Subtract: Adjusted EBITDA attributable to Previous Owners (4) — — 1.5 Adjusted EBITDA attributable to noncontrolling interest (5) 3.4 3.3 8.3 Adjusted EBITDA attributable to SunCoke Energy Partners $ 221.3 $ 209.7 $ 191.5 Years Ended December 31, 2017 2016 2015 (Dollars in millions) Net cash provided by operating activities $ 136.7 $ 183.6 $ 149.4 Add: Cash interest paid 65.6 54.0 49.8 Cash taxes paid 1.4 1.5 0.8 Changes in working capital 20.2 (17.8 ) 7.1 Contingent consideration adjustments (1) (1.7 ) (10.1 ) — Non-cash reversal of acquired contractual obligation (2) — (0.7 ) (3.3 ) Other adjustments to reconcile cash provided by operating activities to Adjusted EBITDA 2.5 2.5 (2.5 ) Adjusted EBITDA (3) $ 224.7 $ 213.0 $ 201.3 Subtract: Adjusted EBITDA attributable to Previous Owner (4) — — 1.5 Adjusted EBITDA attributable to noncontrolling interest (5) 3.4 3.3 8.3 Adjusted EBITDA attributable to SunCoke Energy Partners $ 221.3 $ 209.7 $ 191.5 (1) As a result of changes in the fair value of the contingent consideration liability, the Partnership recognized benefits of $1.7 million and $10.1 million during 2017 and 2016, respectively. See Note 15 . (2) In association with the acquisition of CMT, we assumed certain performance obligations under existing contracts and recorded liabilities related to such obligations. In 2015 and 2016, the final acquired contractual performance obligations expired without the customer requiring performance. Therefore, the Partnership reversed the liabilities as we no longer have any obligations under the contracts. (3) In accordance with the SEC’s May 2016 update of its guidance on the appropriate use of non-GAAP financial measures, Adjusted EBITDA does not include Logistics deferred revenue until it is recognized as GAAP revenue. (4) Reflects net income attributable to our Granite City facility prior to the Granite City Dropdown on January 13, 2015 adjusted for Granite City's share of interest, taxes, depreciation and amortization during the same period. (5) Reflects net income attributable to noncontrolling interest adjusted for noncontrolling interest's share of interest, taxes, income, and depreciation and amortization. |

See Note 7 . (2) During the second quarter of 2017, the Partnership incurred $19.9 million of losses in connection with debt refinancing. See Note 12 . (3) During the fourth quarter of 2017, the Partnership recorded $68.8 million of tax benefits as a result of the new Tax Legislation. See Note 7 . (4) The Partnership recognized deferred revenue from Logistics take-or-pay billings for minimum volume shortfalls of $16.4 million and $31.5 million into revenue in the fourth quarters of 2017 and 2016 respectively. (5) Gross profit equals sales and other operating revenue less cost of products sold and operating expenses and depreciation and amortization. (6) Net income per common unit is computed independently for each of the quarters presented. Therefore, the sum of quarterly net income per common unit information may not equal annual net income per common unit. The deferred tax liabilities recorded in the first quarter of 2017 as a result of the Final Regulations on qualifying income were revised by the new Tax Legislation, enacted in the fourth quarter of 2017. Our full year net loss per common unit calculation was impacted as a result. |
Summary of Significant Accoun24
Summary of Significant Accounting Policies (Policies) | 12 Months Ended |
Dec. 31, 2017 | |
Accounting Policies [Abstract] | |
Use of Estimates | Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the combined and consolidated financial statements and accompanying notes. Actual amounts could differ from these estimates. |
Revenue Recognition | Revenue Recognition The Partnership sells coke as well as steam and electricity and also provides mixing and handling services of coal and other aggregates. Revenues related to the sale of products are recognized when title passes, generally when products are shipped or delivered in accordance with the terms of the respective sales agreements. Service revenues are recognized when services are provided as defined by customer contracts. Revenues are not recognized until sales prices are fixed or determinable and collectability is reasonably assured. Substantially all of the coke produced by the Partnership is sold pursuant to long-term contracts with its customers. The Partnership evaluates each of its contracts to determine whether the arrangement contains a lease under the applicable accounting standards. If the specific facts and circumstances indicate that it is remote that parties other than the contracted customer will take more than a minor amount of the coke that will be produced by the property, plant and equipment during the term of the coke supply agreement, and the price that the customer is paying for the coke is neither contractually fixed per unit nor equal to the current market price per unit at the time of delivery, then the long-term contract is deemed to contain a lease. The lease component of the price of coke represents the rental payment for the use of the property, plant and equipment, and all such payments are accounted for as contingent rentals as they are only earned by the Partnership when the coke is delivered and title passes to the customer. The total amount of revenue recognized by the Partnership for these contingent rentals represents less than 10 percent of sales and other operating revenues for each of the years ended December 31, 2017 , 2016 and 2015 . The Partnership receives payment for shortfall obligations on certain logistics take-or-pay contracts. The payments in excess of service performed is recorded in deferred revenue on the Consolidated Balance Sheets. Deferred revenue on take-or-pay contracts is generally billed quarterly and recognized as income at the earlier of when service is provided or annually based on the terms of the contract. |
Cash Equivalents | Cash Equivalents The Partnership considers all highly liquid investments with a remaining maturity of three months or less at the time of purchase to be cash equivalents. These cash equivalents consist principally of money market investments. |
Inventories | Inventories Inventories are valued at the lower of cost or net realizable value. Cost is determined using the first-in, first-out method, except for the Partnership’s materials and supplies inventory, which are determined using the average-cost method. The Partnership utilizes the selling prices under its long-term coke supply contracts to record lower of cost or net realizable value inventory adjustments. |
Properties, Plants and Equipment | Properties, Plants and Equipment Plants and equipment are depreciated on a straight-line basis over their estimated useful lives. Coke and energy plant, machinery and equipment are generally depreciated over 25 to 30 years . Logistics plant and equipment are generally depreciated over 15 to 35 years . Depreciation and amortization is excluded from cost of products sold and operating expenses and is presented separately in the Combined and Consolidated Statements of Operations. Gains and losses on the disposal or retirement of fixed assets are reflected in earnings when the assets are sold or retired. Amounts incurred that extend an asset’s useful life, increase its productivity or add production capacity are capitalized. The Partnership capitalized interest of $1.1 million , $5.0 million and $3.7 million in 2017, 2016 and 2015 , respectively. Direct costs, such as outside labor, materials, internal payroll and benefits costs, incurred during capital projects are capitalized; indirect costs are not capitalized. Normal repairs and maintenance costs are expensed as incurred. |
Impairment of Long-Lived Assets | Impairment of Long-Lived Assets Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. A long-lived asset, or group of assets, is considered to be impaired when the undiscounted net cash flows expected to be generated by the asset are less than its carrying amount. Such estimated future cash flows are highly subjective and are based on numerous assumptions about future operations and market conditions. The impairment recognized is the amount by which the carrying amount exceeds the fair market value of the impaired asset, or group of assets. It is also difficult to precisely estimate fair market value because quoted market prices for our long-lived assets may not be readily available. Therefore, fair market value is generally based on the present values of estimated future cash flows using discount rates commensurate with the risks associated with the assets being reviewed for impairment. |
Goodwill and Other Intangibles | Goodwill and Other Intangibles Goodwill, which represents the excess of the purchase price over the fair value of net assets acquired, is tested for impairment as of October 1 of each year, or when events occur or circumstances change that would, more likely than not, reduce the fair value of a reporting unit to below its carrying value. The Partnership performs its annual goodwill impairment test by comparing the fair value of the reporting unit with its carrying amount. The Partnership would recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value. Intangible assets are primarily comprised of permits, customer contracts and customer relationships. Intangible assets are amortized over their useful lives in a manner that reflects the pattern in which the economic benefit of the intangible asset is consumed. Intangible assets are assessed for impairment when a triggering event occurs. |
Asset Retirement Obligations | Asset Retirement Obligations The fair value of a liability for an asset retirement obligation is recognized in the period in which it is incurred if a reasonable estimate of fair value can be made. The associated asset retirement costs are capitalized as part of the carrying amount of the asset and depreciated over its remaining estimated useful life. At December 31, 2017 and 2016 , Granite City had asset retirement obligations of $6.5 million and $6.1 million , respectively, primarily related to costs associated with restoring land to its original state, which are included in other deferred credits and liabilities on the Consolidated Balance Sheets. |
Shipping and Handling Costs | Shipping and Handling Costs Shipping and handling costs are included in cost of products sold and operating expenses and are generally passed through to our customers. |
Income Taxes | Income Taxes Deferred tax asset and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those differences are projected to be recovered or settled. See Note 7 for discussion of the impacts of the Tax Cuts and Jobs Act (“Tax Legislation”), which was enacted on December 22, 2017. The Partnership recognizes uncertain tax positions in its financial statements when minimum recognition threshold and measurement attributes are met in accordance with current accounting guidance. |
Fair Value Measurements | Fair Value Measurements The Partnership determines fair value 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 the measurement date. As required, the Partnership utilizes valuation techniques that maximize the use of observable inputs (levels 1 and 2) and minimize the use of unobservable inputs (level 3) within the fair value hierarchy included in current accounting guidance. Assets and liabilities are classified within the fair value hierarchy based on the lowest level (least observable) input that is significant to the measurement in its entirety. |
Recently Issued Pronouncements | Recently Issued Pronouncements In May 2014, Financial Accounting Standards Board ("FASB") issued ASU 2014-09, “Revenue from Contracts with Customers (Topic 606),” which supersedes the revenue recognition requirements in “Revenue Recognition (Topic 605),” and requires entities to recognize revenue to depict the transfer of 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. Subsequently, the FASB has issued various ASUs to provide further clarification around certain aspects of ASC 606. This standard will be effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period, and early adoption was permitted on a limited basis. We have substantially completed our analysis of the new standard and do not expect a material change in our revenue recognition model on an annual basis. Deferred revenue at CMT may be recognized on a more accelerated basis during quarterly periods within the year based on facts and circumstances considered at each quarter under the new guidance. The Partnership will adopt this standard on January 1, 2018 using the modified retrospective method. In February 2016, the FASB issued ASU 2016-02, "Leases (Topic 842)." ASU 2016-02 requires lessees to recognize assets and liabilities on the balance sheet for the rights and obligations created by all leases with terms of more than 12 months. It is effective for annual and interim periods in fiscal years beginning after December 15, 2018, with early adoption permitted. A multi-disciplined implementation team has gained an understanding of the accounting and disclosure provisions of the standard and is in the process of analyzing the impacts to our business, including the development of new accounting processes to account for our leases and support the required disclosures. While we are still evaluating the impact of adopting this standard, we expect that upon adoption the right-of-use assets and lease liabilities, such as various plant equipment rentals and the lease of our corporate office space, will increase the reported assets and liabilities on our Consolidated Balance Sheets. We are currently evaluating technology tools to assist with the accounting and reporting requirements of this standard. The Partnership expects to adopt this standard on January 1, 2019 and is currently evaluating our transition method options. |

Reconciliation of Adjusted EBITDA (unaudited) to net income | Below are reconciliations of Adjusted EBITDA from net (loss) income and net cash provided by operating activities, which are its most directly comparable financial measures calculated and presented in accordance with GAAP: Years Ended December 31, 2017 2016 2015 (Dollars in millions) Net (loss) income $ (17.5 ) $ 121.4 $ 92.2 Add: Depreciation and amortization expense 83.6 77.7 67.4 Interest expense, net 56.4 47.7 48.2 Loss (gain) on extinguishment of debt 20.0 (25.0 ) (0.7 ) Income tax expense (benefit) 83.9 2.0 (2.5 ) Contingent consideration adjustments (1) (1.7 ) (10.1 ) — Non-cash reversal of acquired contractual obligations (2) — (0.7 ) (3.3 ) Adjusted EBITDA (3) $ 224.7 $ 213.0 $ 201.3 Subtract: Adjusted EBITDA attributable to Previous Owners (4) — — 1.5 Adjusted EBITDA attributable to noncontrolling interest (5) 3.4 3.3 8.3 Adjusted EBITDA attributable to SunCoke Energy Partners $ 221.3 $ 209.7 $ 191.5 Years Ended December 31, 2017 2016 2015 (Dollars in millions) Net cash provided by operating activities $ 136.7 $ 183.6 $ 149.4 Add: Cash interest paid 65.6 54.0 49.8 Cash taxes paid 1.4 1.5 0.8 Changes in working capital 20.2 (17.8 ) 7.1 Contingent consideration adjustments (1) (1.7 ) (10.1 ) — Non-cash reversal of acquired contractual obligation (2) — (0.7 ) (3.3 ) Other adjustments to reconcile cash provided by operating activities to Adjusted EBITDA 2.5 2.5 (2.5 ) Adjusted EBITDA (3) $ 224.7 $ 213.0 $ 201.3 Subtract: Adjusted EBITDA attributable to Previous Owner (4) — — 1.5 Adjusted EBITDA attributable to noncontrolling interest (5) 3.4 3.3 8.3 Adjusted EBITDA attributable to SunCoke Energy Partners $ 221.3 $ 209.7 $ 191.5 (1) As a result of changes in the fair value of the contingent consideration liability, the Partnership recognized benefits of $1.7 million and $10.1 million during 2017 and 2016, respectively. See Note 15 . (2) In association with the acquisition of CMT, we assumed certain performance obligations under existing contracts and recorded liabilities related to such obligations. In 2015 and 2016, the final acquired contractual performance obligations expired without the customer requiring performance. Therefore, the Partnership reversed the liabilities as we no longer have any obligations under the contracts. (3) In accordance with the SEC’s May 2016 update of its guidance on the appropriate use of non-GAAP financial measures, Adjusted EBITDA does not include Logistics deferred revenue until it is recognized as GAAP revenue. (4) Reflects net income attributable to our Granite City facility prior to the Granite City Dropdown on January 13, 2015 adjusted for Granite City's share of interest, taxes, depreciation and amortization during the same period.

See Note 7 . (2) During the second quarter of 2017, the Partnership incurred $19.9 million of losses in connection with debt refinancing. See Note 12 . (3) During the fourth quarter of 2017, the Partnership recorded $68.8 million of tax benefits as a result of the new Tax Legislation. See Note 7 . (4) The Partnership recognized deferred revenue from Logistics take-or-pay billings for minimum volume shortfalls of $16.4 million and $31.5 million into revenue in the fourth quarters of 2017 and 2016 respectively. (5) Gross profit equals sales and other operating revenue less cost of products sold and operating expenses and depreciation and amortization. (6) Net income per common unit is computed independently for each of the quarters presented. Therefore, the sum of quarterly net income per common unit information may not equal annual net income per common unit. The deferred tax liabilities recorded in the first quarter of 2017 as a result of the Final Regulations on qualifying income were revised by the new Tax Legislation, enacted in the fourth quarter of 2017. Our full year net loss per common unit calculation was impacted as a result. |
