CORPORATE STRUCTURE AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Nature of Operations

The unaudited condensed consolidated financial statements are composed of Ciner Resources LP (the “Partnership,” “CINR,” “Ciner Resources,” “we,” “us,” or “our”), a publicly traded Delaware limited partnership, and its consolidated subsidiary, Ciner Wyoming LLC (“Ciner Wyoming”), which is in the business of mining trona ore to produce soda ash. The Partnership’s operations consist solely of its investment in Ciner Wyoming. The Partnership was formed in April 2013 by Ciner Wyoming Holding Co. (“Ciner Holdings”), a wholly-owned subsidiary of Ciner Resources Corporation (“Ciner Corp”). Ciner Corp is a direct wholly-owned subsidiary of Ciner Enterprises Inc. (“Ciner Enterprises”), which is directly owned by Akkan Enerji ve Madencilik Anonim Şirketi (“Akkan”), which in turn is directly wholly-owned by Turgay Ciner, the Chairman of the Ciner Group, a Turkish conglomerate of companies engaged in energy and mining (including soda ash mining), media and shipping markets. The Partnership owns a controlling interest comprised of 51.0% membership interest in Ciner Wyoming. All our soda ash processed is currently sold to various domestic and international customers including ANSAC and CIDT, both of which are affiliates for export sales. All mining and processing activities take place in one facility located in the Green River Basin of Wyoming.

Basis of Presentation and Significant Accounting Policies
The accompanying unaudited condensed consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles (“GAAP”) applicable to interim period financial statements and reflect all adjustments, consisting of normal recurring accruals, which are necessary for fair presentation of the results of operations, financial position and cash flows for the periods presented. All significant intercompany transactions, balances, revenue and expenses have been eliminated in consolidation. The results of operations for the period ended September 30, 2017 are not necessarily indicative of the operating results for the full year.
These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes to audited consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2016 (the “2016 Annual Report”). There has been no material change in the significant accounting policies followed by us during the nine month period ended September 30, 2017 from those disclosed in the 2016 Annual Report.
Non-controlling interests

NRP Trona LLC, a wholly-owned subsidiary of Natural Resource Partners L.P. ("NRP"), currently owns a 49.0% membership interest in Ciner Wyoming.
        
Use of Estimates
The preparation of these unaudited condensed consolidated financial statements, in accordance with GAAP, requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities at the dates of the unaudited condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Subsequent Events
We have evaluated subsequent events through the filing date of this Quarterly Report on Form 10-Q.
Recently Issued Accounting Pronouncements
In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (Topic 606) that requires companies to recognize revenue when a customer obtains control rather than when companies have transferred substantially all risks and rewards of a good or service. The Partnership should apply the guidance in ASU 2014-09 to annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. The Partnership is completing its evaluation of the provisions of this ASU and does not expect our adoption of ASU 2014-09 to materially change the amount or timing of revenues recognized by us, nor expect it to materially affect our financial position. The majority of our revenues generated are recognized upon delivery and transfer of title to the product to our customers. The time at which delivery and transfer of title occurs, for the majority of our contracts with customers, is the point when the product leaves our facility, thereby rendering our performance obligation fulfilled. The FASB issued various amendments to ASU 2014-09, one of which includes allowing entities to elect to account for shipping and handling activities performed after the control of a good has been transferred to the customer as a fulfillment cost versus an obligation of a promised service. The Partnership expects to make this an accounting policy election upon adoption to account for shipping and handling activities as fulfillment costs. The Partnership will adopt this ASU effective January 1, 2018, as permitted by the ASU.
In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities (ASU 2016-01). The standard amends certain aspects of recognition, measurement, presentation, and disclosure of financial assets and liabilities. ASU 2016-01 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017. The Partnership is currently evaluating the potential impact the adoption of ASU No. 2016-01 will have on our unaudited condensed consolidated financial statements, as well as available transition methods.
In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). The update amends existing standards for accounting for leases by lessees, with accounting for leases by lessors remaining largely unchanged from current guidance. The update requires that lessees recognize a lease liability and a right of use asset for all leases (with the exception of short-term leases) at the commencement date of the lease and disclose key information about leasing arrangements. The update is effective for interim and annual periods beginning after December 15, 2018 and must be adopted using a modified retrospective transition. The ASU No. 2016-02 provides for certain practical expedients and early adoption is permitted. The Partnership is evaluating the potential impact the adoption of ASU No. 2016-02 will have on its unaudited condensed consolidated financial statements.
In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which is intended to improve financial reporting by requiring timelier recording of credit losses on loans and other financial instruments held by financial institutions and other organizations. This ASU requires an organization to measure all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Financial institutions and other organizations will now use forward-looking information to better inform their credit loss estimates. The amendments in this ASU are effective for fiscal years beginning after December 15, 2019, and for interim periods therein. Early application will be permitted for all organizations for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. The Partnership is evaluating the effect the standard will have on its unaudited condensed consolidated financial statements.
NET INCOME PER UNIT AND CASH DISTRIBUTION
NET INCOME PER UNIT AND CASH DISTRIBUTION
NET INCOME PER UNIT AND CASH DISTRIBUTION
Allocation of Net Income
Net income per unit applicable to limited partners (including subordinated unitholders which were all converted on November 14, 2016) is computed by dividing limited partners’ interest in net income attributable to Ciner Resources, after deducting the general partner’s interest and any incentive distributions, by the weighted average number of outstanding common and subordinated units(which were all converted into common units on November 14, 2016). 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. Earnings in excess of distributions are allocated to the general partner and limited partners based on their respective ownership interests. 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 (which were all converted into common units on November 14, 2016), we have also identified the general partner interest and incentive distribution rights (“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. Potentially dilutive and anti-dilutive units outstanding were immaterial for both the three and nine months ended September 30, 2017 and 2016.

Quarterly Distribution
On October 26, 2017, the Partnership declared its third quarter 2017 quarterly cash distribution of 0.5670 per unit. The quarterly cash distribution is payable on November 20, 2017 to unitholders of record on November 6, 2017.
Our general partner has considerable discretion in determining the amount of available cash, the amount of distributions and the decision to make any distribution. Although our partnership agreement requires that we distribute all of our available cash quarterly, there is no guarantee that we will make quarterly cash distributions to our unitholders at our current quarterly distribution level, at the minimum quarterly distribution level or at any other rate, and we have no legal obligation to do so. However, our partnership agreement does contain provisions intended to motivate our general partner to make steady, increasing and sustainable distributions over time.
Conversion of Subordination Units
Upon payment of the quarterly distribution for the third quarter of 2016, the conditions for conversion of the Partnership’s subordinated units were satisfied. Accordingly, effective on November 14, 2016, the Partnership’s 9,775,500 subordinated units converted into common units on a one-for-one basis.

General Partner Interest and Incentive Distribution Rights
Our partnership agreement provides that our general partner initially will be entitled to 2.0% of all distributions that we make prior to our liquidation. Our general partner has the right, but not the obligation, to contribute up to a proportionate amount of capital to us in order to maintain its 2.0% general partner interest if we issue additional units. Our general partner’s approximate 2.0% interest, and the percentage of our cash distributions to which our general partner is entitled from such approximate 2.0% interest, will be proportionately reduced if we issue additional units in the future (other than (1) the issuance of common units upon conversion of outstanding subordinated units or (2) the issuance of common units upon a reset of the IDRs), and our general partner does not contribute a proportionate amount of capital to us in order to maintain its approximate 2.0% general partner interest. Our partnership agreement does not require that our general partner fund its capital contribution with cash. It may, instead, fund its capital contribution by contributing to us common units or other property.
IDRs represent the right to receive increasing percentages (13.0%, 23.0% and 48.0%) of quarterly distributions from operating surplus after we have achieved the minimum quarterly distribution and the target distribution levels. Our general partner currently holds the IDRs, but may transfer these rights separately from its general partner interest, subject to certain restrictions in our partnership agreement.
Percentage Allocations of Distributions from Operating Surplus
The following table illustrates the percentage allocations of distributions from operating surplus between the unitholders and our general partner based on the specified target distribution levels. The amounts set forth under the column heading “Marginal Percentage Interest in Distributions” are the percentage interests of our general partner and the unitholders in any distributions from operating surplus we distribute up to and including the corresponding amount in the column “Total Quarterly Distribution per Unit Target Amount.” The percentage interests shown for our unitholders and our general partner for the minimum quarterly distribution also apply to quarterly distribution amounts that are less than the minimum quarterly distribution. The percentage interests set forth below for our general partner (1) include its 2.0% general partner interest, (2) assume that our general partner has contributed any additional capital necessary to maintain its 2.0% general partner interest, (3) assume that our general partner has not transferred its IDRs and (4) assume there are no arrearages on common units.

On August 1, 2017, Ciner Wyoming entered into a Credit Agreement (the “Ciner Wyoming Credit Facility”).  The new facility consists of a $225.0 million senior unsecured revolving credit facility with a maturity date of August 1, 2022. Loans under the Ciner Wyoming Credit Facility bear interest at Ciner Wyoming’s option at either a Base Rate or a Eurodollar Rate.  Each Eurodollar Rate Loan bears interest at a Eurodollar Rate plus an applicable margin.  Each Base Rate Loan bears interest at a Base Rate plus an applicable margin.  The Base Rate equals the highest of (i) the federal funds rate in effect on such day plus 0.50%, (ii) the administrative agent’s prime rate in effect on such day or (iii) one-month London Interbank Offered Rate “LIBOR” plus 1.0%.The Ciner Wyoming Credit Facility also requires quarterly maintenance of a consolidated leverage ratio (as defined in the Ciner Wyoming Credit Facility) of not more than 3.00 to 1.00 and a consolidated interest coverage ratio (as defined in the Ciner Wyoming Credit Facility) of not less than 3.00 to 1.00. The Ciner Wyoming Credit Facility replaces the former Credit Facility (the “Former Ciner Wyoming Credit Facility”), dated as of July 18, 2013, by and among Ciner Wyoming, which was terminated on August 1, 2017 upon entry into the new Ciner Wyoming Credit Facility.  This arrangement was accounted for as a modification of debt in accordance with Accounting Standards Codification (“ASC”) 470-50.

EMPLOYEE COMPENSATION
EMPLOYEE COMPENSATION
EMPLOYEE COMPENSATION

The Partnership participates in various benefit plans offered and administered by Ciner Corp and is allocated its portions of the annual costs related thereto. The specific plans are as follows:
Retirement Plans - Benefits provided under the pension plan for salaried employees and pension plan for hourly employees (collectively, the “Retirement Plans”) are based upon years of service and average compensation for the highest 60 consecutive months of the employee’s last 120 months of service, as defined. Each plan covers substantially all full-time employees hired before May 1, 2001. The funding policy is to contribute an amount within the range of the minimum required and the maximum tax-deductible contribution. The Partnership’s allocated portion of the Retirement Plan’s net periodic pension costs for both the three months ended September 30, 2017 and 2016 were $0.1 million and $0.4 million, respectively, and $1.0 million and $1.5 million for the nine months ended September 30, 2017 and 2016, respectively. The decrease in pension costs during the nine months ended September 30, 2017 of $0.5 million was driven by improved discount rates.
Savings Plan - The 401(k) retirement plan (the “401(k) Plan”) covers all eligible hourly and salaried employees. Eligibility is limited to all domestic residents and any foreign expatriates who are in the United States indefinitely. The plan permits employees to contribute specified percentages of their compensation, while the Partnership makes contributions based upon specified percentages of employee contributions. Participants hired on or subsequent to May 1, 2001, will receive an additional contribution from the Partnership based on a percentage of the participant’s base pay. Contributions made to the 401(k) Plan for the three months ended September 30, 2017 and 2016, were $0.8 million and $0.5 million, respectively, and $3.3 million and $1.3 million for the nine months ended September 30, 2017 and 2016, respectively. The increase during the nine months ended ended September 30, 2017 was primarily due to the incremental contributions that were not made in the prior year’s comparative period due the the acquisition of the Partnership’s parent company and the accelerated payouts in 2015. See our 2016 Annual Report for further discussion on the acquisition of the Partnership’s parent company.
Postretirement Benefits - Most of the Partnership’s employees are eligible for postretirement benefits other than pensions if they reach retirement age while still employed.
The postretirement benefits are accounted for on an accrual basis over an employee’s period of service. The postretirement plan, excluding pensions, are not funded, and Ciner Corp has the right to modify or terminate the plan. The post-retirement benefits had a benefits obligation of $11.2 million and $20.6 million at September 30, 2017 and December 31, 2016, respectively. The decrease in the obligation as of September 30, 2017 as compared to December 31, 2016 is due to the Partnership amending its postretirement benefit plan to increase eligibility requirements at which participants may begin receiving benefits, implemented a subsidy rather than a premium for the benefit plan, and eliminating plan eligibility for individuals hired after December 31, 2016.
The Partnership’s allocated portion of postretirement (benefit) costs for the three months ended September 30, 2017 and 2016, were $(0.6) million and $0.3 million, respectively, and $(2.1) million and $1.0 million for the nine months ended September 30, 2017 and 2016, respectively. The decrease in postretirement expense for the Partnership in 2017 is due to the aforementioned changes made to the postretirement benefit plans during 2017.
EQUITY - BASED COMPENSATION

EQUITY - BASED COMPENSATION
We grant various types of equity-based awards to participants, including time restricted unit awards and total return restricted performance unit awards (“TR Performance Unit Awards”). The key terms of our restricted unit awards and TR Performance Unit Awards, including all financial disclosures, are set forth in our 2016 Annual Report.
All employees, officers, consultants and non-employee directors of us and our parents and subsidiaries are eligible to be selected to participate in the Ciner Resource Partners LLC 2013 Long-Term Incentive Plan (the “Plan” or “LTIP”). As of September 30, 2017, subject to further adjustment as provided in the Plan, a total of 0.7 million common units were available for awards under the Plan. Any common units tendered by a participant in payment of the tax liability with respect to an award, including common units withheld from any such award, will not be available for future awards under the Plan. Common units awarded under the Plan may be reserved or made available from our authorized and unissued common units or from common units reacquired (through open market transactions or otherwise). Any common units issued under the Plan through the assumption or substitution of outstanding grants from an acquired company will not reduce the number of common units available for awards under the Plan. If any common units subject to an award under the Plan are forfeited, those forfeited units will again be available for awards under the Plan. In January 2017, the Company adopted ASU No. 2016-09 which permits us to recognize forfeitures as incurred. Consequently, no estimated forfeiture rate was applied to the awards during the three and nine months ended September 30, 2017.
Non-employee Director Awards
During the nine months ended September 30, 2017, a total of 7,887 common units were granted and fully vested to non-employee directors, and 7,251 were granted during the nine months ended September 30, 2016. The grant date average fair value per unit of these awards was $27.53 and $26.24 for the nine months ended September 30, 2017 and 2016, respectively. The total fair value of these awards were approximately $0.2 million during the nine months ended September 30, 2017 and 2016, respectively.
Time Restricted Unit Awards
We grant restricted unit awards in the form of common units to certain employees which vest over a specified period of time, usually between one to three years, with vesting based on continued employment as of each applicable vesting date. Award recipients are entitled to distributions subject to the same restrictions as the underlying common unit. The awards are classified as equity awards, and are accounted for at fair value at grant date.

Total Return Performance Unit Awards
We grant TR Performance Unit Awards to certain employees. The TR Performance Unit Awards represent the right to receive a number of common units at a future date based on the achievement of market-based performance requirements in accordance with the TR Unit Performance Award agreement, and also include Distribution Equivalent Rights (“DERs”). DERs are the right to receive an amount equal to the accumulated cash distributions made during the period with respect to each common unit issued upon vesting. The TR Performance Unit Awards vest at the end of the performance period, usually between two to three years from the date of the grant. Performance is measured on the achievement of a specified level of total return, or TR, relative to the TR of a peer group comprised of other limited partnerships. The potential payout ranges from 0-200% of the grant target quantity and is adjusted based on our TR performance relative to the peer group.
We utilized a Monte Carlo simulation model to estimate the grant date fair value of TR Performance Unit A wards, with market conditions, granted to employees. These type of awards require the input of highly subjective assumptions, including expected volatility and expected distribution yield. Historical and implied volatilities were used in estimating the fair value of these awards.

COMMITMENTS AND CONTINGENCIES
From time to time we are party to various claims and legal proceedings related to our business. Although the outcome of these proceedings cannot be predicted with certainty, management does not currently expect any of the legal proceedings we are involved in to have a material effect on our business, financial condition and results of operations. We cannot predict the nature of any future claims or proceedings, nor the ultimate size or outcome of existing claims and legal proceedings and whether any damages resulting from them will be covered by insurance.
Off-Balance Sheet Arrangements
We have a self-bond agreement with the Wyoming Department of Environmental Quality under which we commit to pay directly for reclamation costs. The amount of the bond was $32.9 million and $38.2 million as of September 30, 2017 and December 31, 2016, which is the amount we would need to pay the State of Wyoming for reclamation costs if we cease mining operations currently. The amount of this self-bond is subject to change upon periodic re-evaluation by the Land Quality Division.

Ciner Wyoming’s revenue bonds require it to maintain stand-by letters of credit totaling $11.6 million and $20.0 million as of September 30, 2017 and December 31, 2016.
AGREEMENTS AND TRANSACTIONS WITH AFFILIATES
AGREEMENTS AND TRANSACTIONS WITH AFFILIATES
AGREEMENTS AND TRANSACTIONS WITH AFFILIATES
Ciner Corp is the exclusive sales agent for the Partnership and through its membership in ANSAC, Ciner Corp is responsible for promoting and increasing the use and sale of soda ash and other refined or processed sodium products produced. All actual sales and marketing costs incurred by Ciner Corp are charged directly to the Partnership. Selling, general and administrative expenses also include amounts charged to the Partnership by its affiliates principally consisting of salaries, benefits, office supplies, professional fees, travel, rent and other costs of certain assets used by the Partnership. On October 23, 2015 the Partnership entered into a Services Agreement (the “Services Agreement”), among the Partnership, our general partner and Ciner Corp. Pursuant to the Services Agreement, Ciner Corp has agreed to provide the Partnership with certain corporate, selling, marketing, and general and administrative services, in return for which the Partnership has agreed to pay Ciner Corp an annual management fee and reimburse Ciner Corp for certain third-party costs incurred in connection with providing such services. In addition, under the joint venture agreement governing Ciner Wyoming, Ciner Wyoming reimburses us for employees who operate our assets and for support provided to Ciner Wyoming. In November 2016, Ciner Corp, on behalf of Ciner Wyoming, entered into a soda ash sales agreement with CIDT, an affiliate of Ciner Group, that sells soda ash to markets not served by ANSAC. The terms of our sales agreement with CIDT are similar to our agreements with other international customers. The receivables associated with these sales are recorded in the accounts receivable—affiliates line item on the unaudited consolidated balance sheets and interest received is recorded in the interest expense, net line item in the unaudited consolidated statement of income. CIDT is ultimately owned and controlled by the Ciner Group. Transactions with our affiliates do not necessarily represent arm's length transactions and may not represent all costs if the Partnership operated on a stand-alone basis.
The total costs charged to the Partnership by affiliates for each period presented were as follows:

Cost of products sold includes freight costs charged by ANSAC. For the three months ended September 30, 2017 and 2016, these costs were $3.2 million and $0.4 million, respectively, and $16.8 million and $1.2 million for the nine months ended September 30, 2017 and 2016, respectively. The increase in freight costs charged by ANSAC was largely due to an increase in non-ANSAC international sales, primarily sales to CIDT, during the nine months ended September 30, 2017 compared to 2016. When we elect to use ANSAC to provide freight services for our other non-ANSAC international sales, ANSAC separately and directly charges the Partnership for such services.

FAIR VALUE MEASUREMENTS
FAIR VALUE MEASUREMENTS
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.
A three-level 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:
Ÿ
Level 1-inputs to the valuation methodology are quoted prices (unadjusted) for an identical asset or liability in an active market.
 
 
Ÿ
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.
 
 
Ÿ
Level 3-inputs to the valuation methodology are unobservable and significant to the fair value measurement of the asset or liability.
Financial instruments consist primarily of cash and cash equivalents, accounts receivable, accounts payable and long-term debt. The carrying amounts of cash and cash equivalents, accounts receivable and accounts payable approximate their fair value because of the nature of such instruments. Our derivative financial instruments are measured at their fair value with Level 2 inputs based on quoted market values for similar but not identical financial instruments.
Financial Assets and Liabilities Measured at Fair Value on a Recurring Basis
Derivative Financial Instruments
We have interest rate swap contracts, designated as cash flow hedges, to mitigate our exposure to possible increases in interest rates. These contracts are for periods consistent with the exposure being hedged and will mature on July 18, 2018, the maturity date of the long-term debt under the Ciner Wyoming credit facility. These contracts had an aggregate notional value of $70.5 million and $72.0 million at September 30, 2017 and December 31, 2016, respectively.
We enter into natural gas forward contracts, designated as cash flow hedges, to mitigate volatility in the price of natural gas related to a portion of the natural gas we consume. These contracts generally have various maturities through 2022. These contracts had an aggregate notional value of $36.6 million and $31.0 million at September 30, 2017 and December 31, 2016, respectively.

On October 26, 2017, the members of the Board of Managers of Ciner Wyoming LLC, approved a cash distribution to the members of Ciner Wyoming in the aggregate amount of $25.0 million. This distribution is payable on November 20, 2017.
On October 26, 2017, the Partnership declared a cash distribution approved by the board of directors of its general partner. The cash distribution for the third quarter of 2017 of $0.5670 per unit will be paid on November 20, 2017 to unitholders of record on November 6, 2017.
CORPORATE STRUCTURE AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)
Nature of Operations

The unaudited condensed consolidated financial statements are composed of Ciner Resources LP (the “Partnership,” “CINR,” “Ciner Resources,” “we,” “us,” or “our”), a publicly traded Delaware limited partnership, and its consolidated subsidiary, Ciner Wyoming LLC (“Ciner Wyoming”), which is in the business of mining trona ore to produce soda ash. The Partnership’s operations consist solely of its investment in Ciner Wyoming. The Partnership was formed in April 2013 by Ciner Wyoming Holding Co. (“Ciner Holdings”), a wholly-owned subsidiary of Ciner Resources Corporation (“Ciner Corp”). Ciner Corp is a direct wholly-owned subsidiary of Ciner Enterprises Inc. (“Ciner Enterprises”), which is directly owned by Akkan Enerji ve Madencilik Anonim Şirketi (“Akkan”), which in turn is directly wholly-owned by Turgay Ciner, the Chairman of the Ciner Group, a Turkish conglomerate of companies engaged in energy and mining (including soda ash mining), media and shipping markets. The Partnership owns a controlling interest comprised of 51.0% membership interest in Ciner Wyoming. All our soda ash processed is currently sold to various domestic and international customers including ANSAC and CIDT, both of which are affiliates for export sales. All mining and processing activities take place in one facility located in the Green River Basin of Wyoming.
Basis of Presentation and Significant Accounting Policies
The accompanying unaudited condensed consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles (“GAAP”) applicable to interim period financial statements and reflect all adjustments, consisting of normal recurring accruals, which are necessary for fair presentation of the results of operations, financial position and cash flows for the periods presented. All significant intercompany transactions, balances, revenue and expenses have been eliminated in consolidation. The results of operations for the period ended September 30, 2017 are not necessarily indicative of the operating results for the full year.
These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes to audited consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2016 (the “2016 Annual Report”). There has been no material change in the significant accounting policies followed by us during the nine month period ended September 30, 2017 from those disclosed in the 2016 Annual Report.
Non-controlling interests

NRP Trona LLC, a wholly-owned subsidiary of Natural Resource Partners L.P. ("NRP"), currently owns a 49.0% membership interest in Ciner Wyoming.
Use of Estimates
The preparation of these unaudited condensed consolidated financial statements, in accordance with GAAP, requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities at the dates of the unaudited condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Subsequent Events
We have evaluated subsequent events through the filing date of this Quarterly Report on Form 10-Q.
Recently Issued Accounting Pronouncements
In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (Topic 606) that requires companies to recognize revenue when a customer obtains control rather than when companies have transferred substantially all risks and rewards of a good or service. The Partnership should apply the guidance in ASU 2014-09 to annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. The Partnership is completing its evaluation of the provisions of this ASU and does not expect our adoption of ASU 2014-09 to materially change the amount or timing of revenues recognized by us, nor expect it to materially affect our financial position. The majority of our revenues generated are recognized upon delivery and transfer of title to the product to our customers. The time at which delivery and transfer of title occurs, for the majority of our contracts with customers, is the point when the product leaves our facility, thereby rendering our performance obligation fulfilled. The FASB issued various amendments to ASU 2014-09, one of which includes allowing entities to elect to account for shipping and handling activities performed after the control of a good has been transferred to the customer as a fulfillment cost versus an obligation of a promised service. The Partnership expects to make this an accounting policy election upon adoption to account for shipping and handling activities as fulfillment costs. The Partnership will adopt this ASU effective January 1, 2018, as permitted by the ASU.
In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities (ASU 2016-01). The standard amends certain aspects of recognition, measurement, presentation, and disclosure of financial assets and liabilities. ASU 2016-01 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017. The Partnership is currently evaluating the potential impact the adoption of ASU No. 2016-01 will have on our unaudited condensed consolidated financial statements, as well as available transition methods.
In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). The update amends existing standards for accounting for leases by lessees, with accounting for leases by lessors remaining largely unchanged from current guidance. The update requires that lessees recognize a lease liability and a right of use asset for all leases (with the exception of short-term leases) at the commencement date of the lease and disclose key information about leasing arrangements. The update is effective for interim and annual periods beginning after December 15, 2018 and must be adopted using a modified retrospective transition. The ASU No. 2016-02 provides for certain practical expedients and early adoption is permitted. The Partnership is evaluating the potential impact the adoption of ASU No. 2016-02 will have on its unaudited condensed consolidated financial statements.
In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which is intended to improve financial reporting by requiring timelier recording of credit losses on loans and other financial instruments held by financial institutions and other organizations. This ASU requires an organization to measure all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Financial institutions and other organizations will now use forward-looking information to better inform their credit loss estimates. The amendments in this ASU are effective for fiscal years beginning after December 15, 2019, and for interim periods therein. Early application will be permitted for all organizations for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. The Partnership is evaluating the effect the standard will have on its unaudited condensed consolidated financial statements.

The following table illustrates the percentage allocations of distributions from operating surplus between the unitholders and our general partner based on the specified target distribution levels. The amounts set forth under the column heading “Marginal Percentage Interest in Distributions” are the percentage interests of our general partner and the unitholders in any distributions from operating surplus we distribute up to and including the corresponding amount in the column “Total Quarterly Distribution per Unit Target Amount.” The percentage interests shown for our unitholders and our general partner for the minimum quarterly distribution also apply to quarterly distribution amounts that are less than the minimum quarterly distribution. The percentage interests set forth below for our general partner (1) include its 2.0% general partner interest, (2) assume that our general partner has contributed any additional capital necessary to maintain its 2.0% general partner interest, (3) assume that our general partner has not transferred its IDRs and (4) assume there are no arrearages on common units.
