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"), is a Delaware limited partnership formed in July 2012 , which primarily produces coke used in the blast furnace production of steel. At March 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"). The remaining 2 percent ownership interest in our three cokemaking facilities was owned by SunCoke Energy, Inc. ("SunCoke"). We also own a coal logistics business, which provides coal handling and/or mixing services to third-party customers as well as to our own cokemaking facilities and other SunCoke cokemaking facilities. Our coal logistics business consists of Convent Marine Terminal ("CMT"), Kanawha River Terminals, LLC ("KRT") and SunCoke Lake Terminal, LLC ("Lake Terminal"). At March 31, 2017 , SunCoke, through a subsidiary, owned a 53.9 percent limited partnership interest in us and indirectly owned and controlled our general partner, which holds a 2.0 percent general partner interest in us and all of our incentive distribution rights ("IDR"). Organized in Delaware in 2012 and 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.” Basis of Presentation The accompanying unaudited consolidated financial statements included herein have been prepared in conformity with accounting principles generally accepted in the United States ("GAAP") for interim reporting. Certain information and disclosures normally included in financial statements have been omitted pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC"). In management’s opinion, the financial statements reflect all adjustments, which are of a normal recurring nature, necessary for a fair presentation of the results of operations, financial position and cash flows for the periods presented. The results of operations for the period ended March 31, 2017 are not necessarily indicative of the operating results for the full year. These unaudited interim consolidated financial statements and notes should be read in conjunction with the audited consolidated financial statements and notes included in our Annual Report on Form 10-K for the year ended December 31, 2016 . New Accounting Pronouncements In May 2014, Financial Accounting Standards Board ("FASB") Accounting Standards Update ("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 is permitted on a limited basis. Our implementation team has gained an understanding of the standard’s revenue recognition model and is completing the analysis and documentation of our contract details for impacts under the new revenue recognition model. While we are currently evaluating the impact of the standard, we expect the timing of our revenue recognition to generally remain the same under the new standard on an annual basis. Deferred revenue at Convent Marine Terminal 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 expects to 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. The standard requires the use of a modified retrospective transition method. 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 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. The Partnership expects to adopt this standard on January 1, 2019.

Related Party Transactions [Abstract]
Related Party Transactions and Agreements	2. Related Party Transactions and Agreements Transactions with Affiliate Our coal logistics business provides coal handling and mixing services to certain SunCoke cokemaking operations. Coal Logistics recorded revenues derived from services provided to SunCoke’s cokemaking operations of $2.2 million and $2.6 million for the three months ended March 31, 2017 , and 2016, respectively. Allocated Expenses SunCoke charges us for all direct costs and expenses incurred on our behalf and allocated costs associated with support services provided to our operations. Allocated expenses from SunCoke for general corporate and operations support costs totaled $6.9 million and $7.0 million for the three months ended March 31, 2017 and 2016, respectively, and were included in selling, general and administrative expenses on the Consolidated Statements of Operations. These costs include legal, accounting, tax, treasury, engineering, information technology, insurance, employee benefit costs, communications, human resources, and procurement. Corporate allocations are recorded in accordance with the terms of our omnibus agreement with SunCoke and our general partner. During the second quarter of 2016, SunCoke provided the Partnership with deferred payment terms until April 2017 on the reimbursement of $6.9 million of allocated corporate costs to the Partnership and the $1.4 million IDR cash distribution, resulting in an outstanding payable to SunCoke of $8.3 million included in payable to affiliate, net on the Consolidated Balance Sheets as of March 31, 2017 and December 31, 2016 . Omnibus Agreement In connection with the closing of our initial public offering on January 24, 2013 ("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 United States ("U.S.") and Canada. SunCoke has preferential rights to all other business opportunities. Potential Defaults by Coke Agreement Counterparties. For a period of five years from the closing date of the IPO, SunCoke has agreed to make us whole (including an obligation to pay for coke) to the extent (i) AK Steel exercises the early termination right provided in its Haverhill coke sales agreement, (ii) any customer fails to purchase coke or defaults in payment under its coke sales agreement (other than by reason of force majeure or our default) or (iii) we amend a coke sales agreement's terms to reduce a customer's purchase obligation as a result of the customer's financial distress. We and SunCoke will share in any damages and other amounts recovered from third-parties arising from such events in proportion to our relative losses. Environmental Indemnity. SunCoke will indemnify us to the full extent of any remediation losses at the Haverhill and Middletown cokemaking facilities arising from any environmental matter discovered and identified as requiring remediation prior to the closing of the IPO. In addition, SunCoke will indemnify us for remediation losses at the Granite City cokemaking facility arising from any environmental matter discovered and identified as requiring remediation prior to the closing of the January 2015 dropdown of a 75 percent interest in Granite City ("Granite City Dropdown"). SunCoke contributed $67.0 million in partial satisfaction of this obligation from the proceeds of the IPO, and an additional $52.0 million in connection with subsequent dropdowns. If, prior to the fifth anniversary of the closing of the IPO, a pre-existing environmental matter is identified as requiring remediation, SunCoke will indemnify us for up to $50.0 million of any such remediation costs (we will bear the first $5.0 million of any such costs). 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 or a deferral, whereby the Partnership would be granted extended payment terms. Additionally, we have agreed to pay all 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.

Cash Distributions and Net Income Per Unit Cash Distributions Our partnership agreement generally provides that we will make cash distributions, if any, 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 and • 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 Target Amount Marginal Percentage Interest in Distributions 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.

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. The calculation of net income allocated to the general and limited partners was as follows: Three Months Ended March 31, 2017 2016 (Dollars in millions) Net (loss) income attributable to SunCoke Energy L.P. $ (129.3 ) $ 39.8 Less: Expenses allocated to Common - SunCoke (1) — (7.0 ) Net (loss) income attributable to all partners (129.3 ) 46.8 General partner's incentive distribution rights 1.4 9.4 Net (loss) income attributable to partners, excluding incentive distribution rights (130.7 ) 37.4 General partner's ownership interest: 2.0 % 2.0 % General partner's allocated interest in net (loss) income (2.7 ) 0.7 General partner's incentive distribution rights 1.4 9.4 Total general partner's interest in net (loss) income $ (1.3 ) $ 10.1 Common - public unitholder's interest in net (loss) income $ (57.6 ) $ 16.5 Common - SunCoke interest in net (loss) income: Common - SunCoke interest in net (loss) income (70.4 ) 20.2 Expenses allocated to Common - SunCoke (1) — (7.0 ) Total common - SunCoke interest in net (loss) income (70.4 ) 13.2 Total limited partners' interest in net (loss) income $ (128.0 ) $ 29.7 (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. These expenses are recorded as a direct reduction to SunCoke's interest in net income for the three months ended March 31, 2017 . 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 also have identified the general partner interest and IDRs as participating securities and we 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. The calculation of earnings per unit is as follows: Three Months Ended March 31, 2017 2016 (Dollars and units in millions, except per unit amounts) Net (loss) income attributable to SunCoke Energy L.P. $ (129.3 ) $ 39.8 Less: Expenses allocated to Common - SunCoke — (7.0 ) Net (loss) income attributable to all partners (129.3 ) 46.8 General partner's distributions (including $1.4 million of cash incentive distribution rights in both periods) 2.0 2.0 Limited partners' distributions on common units 27.5 27.5 Distributions less than (greater than) loss/earnings (158.8 ) 17.3 General partner's (loss) earnings: Distributions (including $1.4 million of cash incentive distribution rights in both periods) 2.0 2.0 Allocation of distributions less than (greater than) loss/earnings (3.3 ) 8.1 Total general partner's (loss) earnings (1.3 ) 10.1 Limited partners' (loss) earnings on common units: Distributions 27.5 27.5 Expenses allocated to Common - SunCoke — (7.0 ) Allocation of distributions less than (greater than) loss/earnings (155.5 ) 9.2 Total limited partners' (loss) earnings on common units (128.0 ) 29.7 Limited partners' earnings on subordinated units: Weighted average limited partner units outstanding: Common - basic and diluted 46.2 46.2 Net income per limited partner unit: Common - basic and diluted $ (2.77 ) $ 0.64 Unit Activity Unit activity for the three months ended March 31, 2017 : Common - Public Common - SunCoke Total Common At December 31, 2016 20,800,181 25,415,696 46,215,877 Units issued to directors 4,696 — 4,696 At March 31, 2017 20,804,877 25,415,696 46,220,573

Goodwill and Other Intangible Assets	5. Goodwill and Other Intangible Assets 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. Goodwill allocated to our Coal Logistics segment was $73.5 million at both March 31, 2017 and December 31, 2016 . The components of intangible assets were as follows: March 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 6 $ 24.0 $ 5.3 $ 18.7 $ 24.0 $ 4.5 $ 19.5 Customer relationships 14 28.7 4.3 24.4 28.7 3.8 24.9 Permits 25 139.0 8.3 130.7 139.0 7.1 131.9 Trade name 2 1.2 0.9 0.3 1.2 0.8 0.4 Total $ 192.9 $ 18.8 $ 174.1 $ 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. These permits have an average remaining renewal term of approximately 4.2 years. The permits were renewed regularly prior to our acquisition of CMT. We also 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. Total amortization expense for intangible assets subject to amortization was $2.6 million for both the three months ended March 31, 2017 and 2016.

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	6. Income Taxes At the end of each interim period, we make our best estimate of the effective tax rate expected to be applicable for the full fiscal year and the impact of discrete items, if any, and adjust the rate as necessary. In January 2017, the Internal Revenue Service ("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. However, the Final Regulations include a transition period for activities that were reasonably interpreted to be qualifying income and carried on by publicly traded partnerships prior to the Final Regulations. The Partnership previously received a will-level opinion from its counsel, Vinson & Elkins LLP, that the Partnership's cokemaking operations generated qualifying income prior to the Final Regulations. Therefore, the Partnership believes it had a reasonable basis to conclude its cokemaking operations were considered qualifying income before the issuance of the new regulations and as such expects to maintain its treatment as a partnership through the transition period. Cokemaking entities in the Partnership will become taxable as corporations on January 1, 2028, after the transition period ends. As a result of the Final Regulations, the Partnership recorded deferred income tax expense of $148.6 million during the three months ended March 31, 2017 , primarily related to differences in the book and tax basis of fixed assets, which are expected to exist at the end of the 10-year transition period when the cokemaking operations become taxable. A portion of this deferred tax liability, $3.0 million , was attributable to SunCoke's retained ownership interest in the cokemaking facilities and, therefore, was also reflected as a reduction in noncontrolling interest during the three months ended March 31, 2017.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingent Liabilities	8. Commitments and Contingent Liabilities The United States Environmental Protection Agency (the "EPA") has 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. We retained an aggregate of $119 million in proceeds from the Partnership offering and subsequent dropdowns to fund these environmental remediation projects at the Haverhill and Granite City cokemaking facilities. Pursuant to the omnibus agreement, any amounts that we spend on these projects in excess of the $119 million will be reimbursed by SunCoke. SunCoke spent $7 million related to these projects. We have spent approximately $89 million to date and the remaining capital is expected to be spent through the first quarter of 2019 . 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 consolidated financial statements.

Fair Value Disclosures [Abstract]
Fair Value Measurements	9. 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 March 31, 2017 or December 31, 2016 . Convent Marine Terminal Contingent Consideration In connection with the CMT acquisition, the Partnership entered into a contingent consideration arrangement that requires us 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 both March 31, 2017 and December 31, 2016 was $4.2 million and was included in other deferred charges and liabilities on the Consolidated Balance Sheets. Certain Financial Assets and Liabilities not Measured at Fair Value At March 31, 2017 and December 31, 2016 , the estimated fair value of the Partnership's total debt was $816.7 million and $810.4 million compared to a carrying amount of $ 812.5 million and $813.4 million , respectively. The fair value was estimated by management based upon estimates of debt pricing provided by financial institutions which are considered Level 2 inputs.

Segment Reporting [Abstract]
Business Segment Disclosures	10. Business Segment Disclosures The Partnership derives its revenues from the Domestic Coke and Coal 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 third-party customers primarily 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 ArcelorMittal, 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. Coal Logistics operations are comprised of CMT located in Louisiana, Lake Terminal located in Indiana and KRT located in West Virginia. Our coal logistics operations have a collective capacity to mix and transload approximately 40 million tons of coal annually and provides coal handling and/or mixing services to its customers, which include our own cokemaking facilities and other SunCoke cokemaking facilities. Coal handling and mixing results are presented in the Coal 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. 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: Three Months Ended March 31, 2017 2016 (Dollars in millions) Sales and other operating revenue: Domestic Coke $ 173.2 $ 178.9 Coal Logistics 22.4 15.6 Coal Logistics intersegment sales 1.8 1.5 Elimination of intersegment sales (1.8 ) (1.5 ) Total sales and other operating revenue $ 195.6 $ 194.5 Adjusted EBITDA: Domestic Coke $ 42.5 $ 46.3 Coal Logistics 13.0 5.9 Corporate and Other (3.8 ) (4.0 ) Total Adjusted EBITDA $ 51.7 $ 48.2 Depreciation and amortization expense: Domestic Coke $ 15.7 $ 13.3 Coal Logistics 5.9 5.4 Total depreciation and amortization expense $ 21.6 $ 18.7 Capital expenditures: Domestic Coke $ 3.6 $ 5.9 Coal Logistics 0.6 2.1 Total capital expenditures $ 4.2 $ 8.0 The following table sets forth the Partnership's segment assets: March 31, 2017 December 31, 2016 (Dollars in millions) Segment assets: Domestic Coke $ 1,191.6 $ 1,184.2 Coal Logistics 506.5 510.6 Corporate and Other 0.9 1.2 Total assets $ 1,699.0 $ 1,696.0 The following table sets forth the Partnership’s total sales and other operating revenue by product or service, excluding intersegment revenues: Three Months Ended March 31, 2017 2016 (Dollars in millions) Sales and other operating revenue: Cokemaking revenues $ 158.9 $ 163.4 Energy revenues 13.6 14.7 Coal logistics revenues 20.3 15.3 Other revenues 2.8 1.1 Total revenues $ 195.6 $ 194.5 The Partnership evaluates the performance of its segments based on segment Adjusted EBITDA, which represents earnings before interest, (gain) loss on extinguishment of debt, taxes, depreciation and amortization, adjusted for Coal Logistics 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 is a reconciliation of Adjusted EBITDA (unaudited) to net income and net cash provided by operating activities, which are its most directly comparable financial measures calculated and presented in accordance with GAAP: Three Months Ended March 31, 2017 2016 (1) (Dollars in millions) Net cash provided by operating activities $ 39.4 $ 40.4 Subtract: Depreciation and amortization expense 21.6 18.7 Gain on extinguishment of debt — (20.4 ) Deferred income tax expense 149.2 0.3 Changes in working capital and other 0.3 1.3 Net (loss) income $ (131.7 ) $ 40.5 Add: Depreciation and amortization expense $ 21.6 $ 18.7 Interest expense, net 12.6 12.5 Gain on extinguishment of debt — (20.4 ) Income tax expense, net 149.2 0.6 Contingent consideration adjustments (2) — (3.7 ) Adjusted EBITDA $ 51.7 $ 48.2 Subtract: Adjusted EBITDA attributable to noncontrolling interest (3) 0.8 0.9 Adjusted EBITDA attributable to SunCoke Energy Partners, L.P. $ 50.9 $ 47.3 (1) In response to the SEC’s May 2016 update to its guidance on the appropriate use of non-GAAP financial measures, Adjusted EBITDA no longer includes Coal Logistics deferred revenue until it is recognized as GAAP revenue. As such, Adjusted EBITDA for the three months ended March 31, 2016 has been recast from previously reported results to exclude coal logistics deferred revenue. (2) The Partnership amended its contingent consideration terms with The Cline Group during the first quarter of 2016. These amendments resulted in a gain of $3.7 million recorded during the three months ended March 31, 2016, which was excluded from Adjusted EBITDA. (3) Reflects net income attributable to noncontrolling interest adjusted for noncontrolling interest's share of interest, taxes, income, and depreciation and amortization.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
New Accounting Pronouncements	New Accounting Pronouncements In May 2014, Financial Accounting Standards Board ("FASB") Accounting Standards Update ("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 is permitted on a limited basis. Our implementation team has gained an understanding of the standard’s revenue recognition model and is completing the analysis and documentation of our contract details for impacts under the new revenue recognition model. While we are currently evaluating the impact of the standard, we expect the timing of our revenue recognition to generally remain the same under the new standard on an annual basis. Deferred revenue at Convent Marine Terminal 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 expects to 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. The standard requires the use of a modified retrospective transition method. 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 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. The Partnership expects to adopt this standard on January 1, 2019.
