CINER RESOURCES LP
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)
1. 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 American Natural Soda Ash Corporation (“ANSAC”) and Ciner Ic ve Dis Ticaret Anonim Sirketi (“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 March 31, 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 three month period ended March 31, 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 has completed its initial 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

Table of Content

make this an accounting policy election upon adoption. We currently include freight costs billed to customers for shipments administered by us in gross sales. The Partnership will adopt this ASU effective January 1, 2018, and tentatively expect to apply the modified retrospective (cumulative effect) method of adoption as permitted by the ASU. During 2017, we will develop our revenue disclosures and enhance our accounting systems, if applicable.
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 March 2016, the FASB issued ASU No. 2016-09, Compensation-Stock Compensation- Improvements to Employee Share-Based Payment Accounting (Topic 718), which involves several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, forfeiture calculations, and classification on the statement of cash flows. This ASU is effective for fiscal years beginning after December 15, 2016 including interim periods within that reporting period. The Partnership has adopted the guidance and there was no significant impact on the Partnership’s 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.
2. 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 months ended March 31, 2017 and 2016.

Quarterly Distribution
On April 21, 2017 , the Partnership declared its first quarter 2017 quarterly cash distribution of $0.5670 per unit. The quarterly cash distribution is payable on May 8, 2017 to unitholders of record on May 1, 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.

Table of Content

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.

6. 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 were $0.4 million and

11

Table of Content

$0.6 million for the three months ended March 31, 2017 and 2016 , respectively. The $0.2 million decrease in pension costs during the three months ended March 31, 2017 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 March 31, 2017 and 2016 were $2.1 million and $0.4 million , respectively. The increase during the three months ended March 31, 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 $20.8 million and $20.6 million at March 31, 2017 and December 31, 2016 , respectively. The Partnership’s allocated portion of postretirement benefit costs were $0.6 million and $0.4 million for the three months ended March 31, 2017 and 2016 , respectively.
7. 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 March 31, 2017 , subject to further adjustment as provided in the Plan, a total of 0.8 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 months ended March 31, 2017 .
Non-employee Director Awards
There were no grants of non-employee director awards during the three months ended March 31, 2017 and 2016 .
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.
The following table presents a summary of activity on the Time Restricted Unit Awards:

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 Awards, 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.

9. 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 $38.2 million as of both March 31, 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 $20.3 million as of March 31, 2017 .

10. 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. 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:

									
 	 	Three Months Ended 
 March 31,	
(In millions)	 	2017	 	2016	
Ciner Corp	 	$	3.7		 	$	3.9		
ANSAC  (1)	 	0.3		 	0.7		
Total selling, general and administrative expenses - Affiliates	 	$	4.0		 	$	4.6		

		
 	
(1) ANSAC allocates its expenses to its members using a pro-rata calculation based on sales.
Cost of products sold includes logistics services charged by ANSAC. For the three months ended March 31, 2017 and 2016 , these costs were $8.6 million and $0.4 million , respectively. The increase in logistics services charged by ANSAC was largely due to an increase in international sales during the three months ended March 31, 2017 compared the three months ended March 31, 2016.
Net sales to affiliates were as follows:

11. MAJOR CUSTOMERS AND SEGMENT REPORTING
Our operations are similar in geography, nature of products we provide, and type of customers we serve. As the Partnership earns substantially all of its revenues through the sale of soda ash mined at a single location, we have concluded that we have one operating segment for reporting purposes.
The net sales by geographic area are as follows:

Total net sales	 	$	126.6		 	$	114.4		
12. 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 entered into 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 $71.5 million and $72.0 million at March 31, 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 2021 . These contracts had an aggregate notional value of $25.4 million and $31.0 million at March 31, 2017 and December 31, 2016 , respectively.
The following table presents the fair value of derivative assets and liability derivatives and the respective locations on our unaudited condensed consolidated balance sheets as of March 31, 2017 and December 31, 2016:

Financial Assets and Liabilities not Measured at Fair Value
The carrying value of our long-term debt materially reflects the fair value of our long-term debt as its key terms are similar to indebtedness with similar amounts, durations and credit risks. See Note 4 “Debt” for additional information on our debt arrangements.
13. SUBSEQUENT EVENTS
On April 21, 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 May 8, 2017 .
On April 21, 2017 the Partnership declared a cash distribution approved by the board of directors of its general partner. The cash distribution for the first quarter of 2017 of $0.5670 per unit will be paid on May 15, 2017 to unitholders of record on May 1, 2017 .
In April 2017, Ciner Corp amended 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 eliminated plan eligibility for individuals hired after December 31, 2016.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations
You should read the following management's discussion and analysis of financial condition and results of operations in conjunction with the historical unaudited condensed consolidated financial statements, and notes thereto, included elsewhere in this Report.
Cautionary Statements Regarding Forward-Looking Statements
This Report contains forward-looking statements relating to the financial condition, results of operations, plans, objectives, future performance and business of the Partnership. We have based such forward-looking statements on management’s beliefs and assumptions and on information currently available to us.

Overview
We are a Delaware limited partnership formed by Ciner Holdings to own a 51.0% membership interest in, and to operate the trona ore mining and soda ash production business of, Ciner Wyoming. Ciner Wyoming is currently one of the world’s largest producers of soda ash, serving a global market from its facility in the Green River Basin of Wyoming. Our facility has been in operation for more than 50 years.
NRP Trona LLC, a wholly-owned subsidiary of Natural Resource Partners L.P. (“NRP”) currently owns an indirect 49.0% membership interest in Ciner Wyoming.
Factors Affecting Our Results of Operations
Soda Ash Supply and Demand
Our net sales, earnings and cash flow from operations are primarily affected by the global supply of, and demand for soda ash, which, in turn, directly impacts the prices we and other producers charge for our products.
Demand for soda ash in the United States is driven in large part by general economic growth and activity levels in the end-markets that the glass-making industry serve, such as the automotive and construction industries. Because the United States is a well-developed market, we expect that domestic demand levels will remain stable for the near future. Because future U.S. capacity growth is expected to come from the four major producers in the Green River Basin, we also expect that U.S. supply levels will remain relatively stable in the near term.

Table of Content

Soda ash demand in international markets has continued to grow, although the rate of growth has slowed recently due to sluggish economic growth in emerging markets. We expect that future global economic growth will positively influence global demand, which will likely result in increased exports, primarily from the United States, and to a limited extent, from China, the two largest suppliers of soda ash to international markets.
Sales Mix
Because demand for soda ash in the United States has remained relatively stable in recent years, we have focused on international markets to expand our business, and we expect to continue to do so in the near future. As a result, our operations have been and continue to be sensitive to fluctuations in freight and shipping costs and changes in international prices, which have historically been more volatile than domestic prices. Our gross profit will be impacted by the mix of domestic and international sales as a result of changes in input costs and our average selling prices.
Energy Costs
One of the primary impacts to our profitability is our energy costs. Because we depend upon natural gas and electricity to power our trona ore mining and soda ash processing operations, our net sales, earnings and cash flow from operations are sensitive to changes in the prices we pay for these energy sources. Our cost of energy, particularly natural gas, has been relatively low in recent years, and, despite the historic volatility of natural gas prices, we believe that we will continue to benefit from relatively low prices in the near future. However, we expect to continue to hedge a portion of our forecasted natural gas purchases to mitigate volatility.
How We Evaluate Our Business
Productivity of Operations
Our soda ash production volume is primarily dependent on the following three factors: (1) operating rate, (2) quality of our mined trona ore and (3) recovery rates. Operating rate is a measure of utilization of the effective production capacity of our facilities and is determined in large part by productivity rates and mechanical on-stream times, which is the percentage of actual run times over the total time scheduled. We implement two planned outages of our mining and surface operations each year, typically in the second and third quarters. During these outages, which last approximately one week, we repair and replace equipment and parts. Periodically, we may experience minor unplanned outages caused by various factors, including equipment failures, power outages or service interruptions. The quality of our mine ore is determined by measuring the trona ore recovered as a percentage of the deposit, which includes both trona ore and insolubles. Plant recovery rates are generally determined by calculating the soda ash produced divided by the sum of the soda ash produced plus soda ash that is not recovered from the process. All of these factors determine the amount of trona ore we require to produce one short ton of soda ash and liquor, which we refer to as our “ore to ash ratio.” Our ore to ash ratio was 1.51: 1.0  for both the three months ended March 31, 2017 and 2016 .
Freight and Logistics
The soda ash industry is logistics intensive and involves careful management of freight and logistics costs. These freight costs make up a large portion of the total delivered cost to the customer. Delivered costs to most domestic customers and ANSAC primarily consists of rail freight services. Some domestic customers may elect to arrange their own freight and logistic services. Delivered costs to non-ANSAC international customers primarily consists of both rail freight services to the port of embarkation and the additional ocean freight to the port of disembarkation.
Union Pacific is our largest provider of domestic rail freight services and accounted for 67.8% and 83.2% of our total freight costs during the three months ended March 31, 2017 and 2016 , respectively. The decline in the percentage of freight that is related to Union Pacific is due to the increase in international freight services. Our agreement with Union Pacific generally requires that the freight rate we are charged be increased annually based on a published index tied to certain rail industry metrics. We generally pass on to our customers increases in our freight costs but we may be unsuccessful in doing so.
Net Sales
Net sales include the amounts we earn on sales of soda ash. We recognize revenue from our sales when there is persuasive evidence of an arrangement between us and the customer, products have been delivered to the customer, selling price is fixed, determinable or reasonably estimated and collection is reasonably assured. Substantially all of our sales are derived from sales of soda ash, which we sell through our exclusive sales agent, Ciner Corp. A small amount of our sales is derived from sales of production purge, which is a by-product liquor solution containing soda ash that is produced during the processing of trona ore. For the purposes of our discussion below, we include these transactions in domestic sales of soda ash and in the volume of domestic soda ash sold.
Sales prices for sales through ANSAC include the cost of freight to the ports of embarkation for overseas export or to Laredo, Texas for sales to Mexico. Sales prices for other international sales may include the cost of rail freight to the port of embarkation, the cost of ocean freight to the port of disembarkation for import by the customer and the cost of inland freight required for delivery to the customer.

In November 2016, Ciner Corp, on behalf of Ciner Wyoming, entered into a soda ash sales agreement with Ciner Ic ve Dis Ticaret Anonim Sirketi (“CIDT”) to sell soda ash to markets not served by ANSAC. Sales to CIDT include the cost of rail freight to the port of embarkation and the additional ocean freight to the port of disembarkation.
Cost of products sold
Expenses relating to employee compensation, energy, including natural gas and electricity, royalties and maintenance materials constitute the greatest components of cost of products sold. These costs generally increase in line with increases in sales volume.
Employee Compensation.  See Part I, Item 1. Financial Statements - Note 6 , “Employee Compensation” for information on the various plans.
Energy.    A major item in our cost of products sold is energy, comprised primarily of natural gas and electricity. We primarily use natural gas to fuel our above-ground processing operations, including the heating of calciners, and we use electricity to power our underground mining operations, including our continuous mining machines, or continuous miners, and shuttle cars. The monthly Henry Hub natural gas settlement prices, over the past five years, have ranged between $1.73 and $6.00 per MMBtu. The average monthly Henry Hub natural gas settlement prices as of March 31, 2017 and 2016 were $2.99 and $1.73 per MMBtu, respectively. In order to mitigate the risk of gas price fluctuations, we hedge a portion of our forecasted natural gas purchases by entering into physical or financial gas hedges generally ranging between 20% and 80% of our expected monthly gas requirements, on a sliding scale, for approximately the next five years.
Royalties.     We pay royalties to the State of Wyoming, the U.S. Bureau of Land Management and Rock Springs Royalty Company (“Rock Springs”), an affiliate of Anadarko Petroleum, which are calculated based upon a percentage of the quantity or gross value of soda ash and related products at a certain stage in the mining process, or a certain sum per each ton of such products. These royalty payments are typically subject to a minimum domestic production volume from our Green River Basin facility, although we are obligated to pay minimum royalties or annual rentals to our lessors and licensor regardless of actual sales. We also pay a production tax to Sweetwater County, and trona severance tax to the State of Wyoming that is calculated based on a formula that utilizes the volume of trona ore mined and the value of the soda ash produced.
The royalty rates we pay to our lessors and licensor may change upon our renewal of such leases and license. Under our license with Rock Springs, the applicable royalty rate may vary based on a most favored nation clause in the license. The applicable royalty rate in the license may be adjusted if we pay a higher royalty rate to certain other mineral rights owners in Sweetwater County, Wyoming. The extent to which Rock Springs may increase the applicable royalty rate is currently the subject of litigation in Wyoming. Any increase in the royalty rates we are required to pay to our lessors and licensor, or any failure by us to renew any of our leases and license, could have a material adverse impact on our results of operations, financial condition or liquidity, and, therefore, may affect our ability to distribute cash to unitholders. See Part II, Item 1. “Legal Proceedings” for additional information.
Selling, general and administrative expenses
Selling, general and administrative expenses incurred by our affiliates on our behalf are allocated to us based on the time the employees of those companies spend on our business and the actual direct costs they incur on our behalf. Selling, general and administrative expenses incurred by ANSAC on our behalf are allocated to us based on the proportion of ANSAC’s total volumes sold for a given period attributable to the soda ash sold by us to ANSAC. 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, subject to quarterly adjustments, 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.

Three Months Ended March 31, 2017 compared to Three Months Ended March 31, 2016
Consolidated Results
Net sales . Net sales increased by 10.7% to $126.6 million for the three months ended March 31, 2017 from $114.4 million for the three months ended March 31, 2016 , driven by an increase in total average sales price of 8.9% , and an increase in soda ash volumes sold of 1.6% . The increased sales volumes are primarily due to the 1.9% increase in domestic sales and and sales to CIDT. Sales to CIDT are expected to wind-down in the second-half of fiscal 2017 and we anticipate a corresponding increase in sales to ANSAC.
Cost of products sold. Cost of products sold, including depreciation, depletion and amortization expense, increased by 13.5% to $98.1 million for the three months ended March 31, 2017 from $86.4 million for the three months ended March 31, 2016 , primarily due to an increase in freight costs of 36.8% to $39.8 million for the three months ended March 31, 2017 , compared to $29.1 million for the three months ended March 31, 2016 . The increase in freight costs was driven by higher export sales volumes to CIDT. In the three months ended March 31, 2016, international sales primarily consisted of transactions to ANSAC.
Selling, general and administrative expenses.  Our selling, general and administrative expenses decreased 12.1% to $5.1 million for the three months ended March 31, 2017 , compared to $5.8 million for the three months ended March 31, 2016 . The reduction was primarily driven by lower selling and administrative fees relating to our affiliate, ANSAC, as well as lower professional services fees.
Operating income.    As a result of the foregoing, operating income increased by 5.4% to $23.4 million for the three months ended March 31, 2017 , compared to $22.2 million for the three months ended March 31, 2016 .
Net income.     As a result of the foregoing, net income increased by 6.2% to $22.4 million for the three months ended March 31, 2017 , compared to $21.1 million for the three months ended March 31, 2016 .
Liquidity and Capital Resources
Sources of liquidity include cash generated from operations and borrowings under credit facilities and capital calls from partners. We use cash and require liquidity primarily to finance and maintain our operations, fund capital expenditures for our property, plant and equipment, make cash distributions to holders of our partnership interests, pay the expenses of our general partner and satisfy obligations arising from our indebtedness. Our ability to meet these liquidity requirements will depend on our ability to generate cash flow from operations.
Our sources of liquidity include:

23

Table of Content

•	cash generated from our operations;	

•	Approximately $81 million ($190 million, less $89 million outstanding and less standby letters of credit of $20 million ), is available for borrowing and undrawn under the Ciner Wyoming Credit Facility (as defined in “Debt” below), subject to availability; During the three months ended March 31, 2017 , we had repayments on the Ciner Wyoming Credit Facility of $9.5 million , offset by borrowings of $20.0 million ; and	

•	$10 million available for borrowing under the Revolving Credit Facility (as defined in “Debt” below), subject to availability.	
We expect our ongoing working capital and capital expenditures to be funded by cash generated from operations and borrowings under the Ciner Wyoming Credit Facility. We believe that cash generated from these sources will be sufficient to meet our short-term working capital requirements, long-term capital expenditure requirements and to make quarterly cash distributions. However, we are subject to business and operational risks that could adversely affect our cash flow and access to borrowings under the Revolving Credit Facility and the Ciner Wyoming Credit Facility. Our ability to satisfy debt service obligations, to fund planned capital expenditures and to make acquisitions will depend upon our future operating performance, which, in turn, will be affected by prevailing economic conditions, our business and other factors, some of which are beyond our control.
On January 12, 2017 , the Partnership declared a cash distribution approved by the board of directors of its general partner. The cash distribution for the first quarter 2017 of $0.567 per unit was paid on February 13, 2017 to unitholders of record on January 31, 2017 .
In addition, on April 21, 2017 the Partnership declared a cash distribution approved by the board of directors of its general partner. The cash distribution for the first quarter of 2017 of $0.5670 per unit will be paid on May 15, 2017 to unitholders of record on May 1, 2017 . See Part I, Item 1, Financial Statements - Note 13 , “Subsequent events”, for more information.
We intend to pay a sustainable quarterly distribution and continue to grow our quarterly distribution to unitholders of record over time, to the extent we have sufficient cash from our operations after establishment of cash reserves and payment of fees and expenses, including payments to our general partner and its affiliates. We do not have a legal obligation to pay this distribution.
Capital Requirements
Working capital is the amount by which current assets exceed current liabilities. Our working capital requirements have been, and will continue to be, primarily driven by changes in accounts receivable and accounts payable, which generally fluctuate with changes in volumes, contract terms and market prices of soda ash in the normal course of our business. Other factors impacting changes in accounts receivable and accounts payable could include the timing of collections from customers and payments to suppliers, as well as the level of spending for maintenance and growth capital expenditures. A material adverse change in operations or available financing under the Revolving Credit Facility and the Ciner Wyoming Credit Facility could impact our ability to fund our requirements for liquidity and capital resources. Historically, we have not made working capital borrowings to finance our operations. As of March 31, 2017 , we had a working capital surplus of $91.6 million as compared to a working capital surplus of $80.4 million as of December 31, 2016 .
Capital Expenditures
Our operations require investments to expand, upgrade or enhance existing operations and to meet evolving environmental and safety regulations. We distinguish between maintenance and expansion capital expenditures. Maintenance capital expenditures (including expenditures for the construction or development of new capital assets or the replacement, improvement or expansion of existing capital assets) are made to maintain, over the long term, our operating income or operating capacity. Examples of maintenance capital expenditures are expenditures to upgrade and replace mining equipment and to address equipment integrity, safety and environmental laws and regulations. Our maintenance capital expenditures do not include actual or estimated capital expenditures for replacement of our trona reserves. Expansion capital expenditures are incurred for acquisitions or capital improvements made to increase, over the long term, our operating income or operating capacity. Examples of expansion capital expenditures include the acquisition and/or construction of complementary assets to grow our business and to expand existing facilities, such as projects that increase production from existing facilities, to the extent such capital expenditures are expected to increase our long-term operating capacity or operating income.
The table below summarizes our capital expenditures, on an accrual basis:

Financing activities	(13.1	)	 	(29.9	)	 	(56.2	)%	
Operating Activities
Our operating activities during the three months ended March 31, 2017 provided cash of $10.8 million , a decrease of 70.7% from the $36.8 million cash generated during the three months ended March 31, 2016 , primarily as a result of the following:

•	$18.5 million of working capital used during the three months ended March 31, 2017 , compared to $9.2 million of working capital provided by operating activities during the three months ended March 31, 2016 . The increase in working capital used during the three months ended March 31, 2017 , was primarily due to higher sales volumes to CIDT; partially offset by,	

•	an increase of 6.2% in net income of $22.4 million during the three months ended March 31, 2017 , compared to $21.1 million for the prior-year first quarter.	
Investing Activities
We used cash flows of $6.0 million in investing activities during the three months ended March 31, 2017 , compared to $4.4 million during the three months ended March 31, 2016 , for capital projects as described in “Capital Expenditures” above.
Financing Activities
Cash used in financing activities of $13.1 million during the three months ended March 31, 2017 decreased by 56.2% over the prior-year first quarter, largely due to the change in net borrowings of long-term debt of $10.5 million during the three months ended March 31, 2017 compared to the $6.5 million in repayments during the three months ended March 31, 2016 , partly offset by, the increase in distributions paid during the three months ended March 31, 2017 of $23.6 million compared to the three months ended March 31, 2016 of $23.4 million .

compliance with certain covenants, including minimum net worth, maximum debt to net worth, and interest coverage ratios. As of March 31, 2017 , Ciner Wyoming was in compliance with these debt covenants.
Ciner Wyoming Credit Facility
On July 18, 2013, Ciner Wyoming entered into a $190.0 million senior unsecured revolving credit facility, as amended on October 30, 2014 (as amended, the “Ciner Wyoming Credit Facility”), with a syndicate of lenders, which will mature on the fifth anniversary of the closing date of such credit facility. The Ciner Wyoming Credit Facility provides for revolving loans to fund working capital requirements, capital expenditures, to consummate permitted acquisitions and for all other lawful partnership purposes. The Ciner Wyoming Credit Facility has an accordion feature that allows Ciner Wyoming to increase the available revolving borrowings under the facility by up to an additional $75.0 million, subject to Ciner Wyoming receiving increased commitments from existing lenders or new commitments from new lenders and the satisfaction of certain other conditions. In addition, the Ciner Wyoming Credit Facility includes a sublimit up to $20.0 million for same-day swing line advances and a sublimit up to $40.0 million for letters of credit. Ciner Wyoming’s obligations under the Ciner Wyoming Credit Facility are unsecured.
On May 25, 2016, Ciner Wyoming entered into a Second Amendment to Credit Agreement, First Amendment to Notes and First Amendment to Fee Letter (the “Ciner Wyoming Second Amendment”) with each of the lenders listed on the respective signature pages thereof and Bank of America, N.A., as administrative agent, swing line lender and L/C issuer. The Ciner Wyoming Second Amendment amends the Ciner Wyoming Credit Facility.
Among other things, the Ciner Wyoming Second Amendment (i) amends the Ciner Wyoming Credit Facility by modifying the consolidated fixed charge coverage ratio (the ratio of consolidated cash flow to consolidated fixed charges, each as defined in the Ciner Wyoming Credit Facility) from not less than 1.15 to 1:00, prior to the Ciner Wyoming Second Amendment, to be not less than 1.00 to 1.00 as of the end of any fiscal quarter and (ii) prohibits financial institutions from European Economic Area member countries from serving as loan parties under the Ciner Wyoming Credit Facility.
The Ciner Wyoming Credit Facility contains various covenants and restrictive provisions that limit (subject to certain exceptions) Ciner Wyoming’s ability to:

•	make distributions on or redeem or repurchase units;	

•	incur or guarantee additional debt;	

•	make certain investments and acquisitions;	

•	incur certain liens or permit them to exist;	

•	enter into certain types of transactions with affiliates of Ciner Wyoming;	

•	merge or consolidate with another company; and	

•	transfer, sell or otherwise dispose of assets.	
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 fixed charge coverage ratio (as defined in the Ciner Wyoming Credit Facility) of not less than 1.00 to 1.00. The Ciner Wyoming Credit Facility also requires that consolidated capital expenditures, as defined in the Ciner Wyoming Credit Facility, not exceed $50 million in any fiscal year.
In addition, the Ciner Wyoming Credit Facility contains events of default customary for transactions of this nature, including (i) failure to make payments required under the Ciner Wyoming Credit Facility, (ii) events of default resulting from failure to comply with covenants and financial ratios in the Ciner Wyoming Credit Facility, (iii) the occurrence of a change of control, (iv) the institution of insolvency or similar proceedings against Ciner Wyoming and (v) the occurrence of a default under any other material indebtedness Ciner Wyoming may have. Upon the occurrence and during the continuation of an event of default, subject to the terms and conditions of the Ciner Wyoming Credit Facility, the lenders may terminate all outstanding commitments under the Ciner Wyoming Credit Facility and may declare any outstanding principal of the Ciner Wyoming Credit Facility debt, together with accrued and unpaid interest, to be immediately due and payable.
Under the Ciner Wyoming Credit Facility, a change of control is triggered if Ciner Corp and its wholly-owned subsidiaries, directly or indirectly, cease to own all of the equity interests, or cease to have the ability to elect a majority of the board of directors (or similar governing body) of Ciner GP (or any entity that performs the functions of our general partner). In addition, a change of control would be triggered if we cease to own at least 50.1% of the economic interests in Ciner Wyoming or cease to have the ability to elect a majority of the members of Ciner Wyoming’s board of managers.
Ciner Wyoming was in compliance with all covenants and restrictions under its long-term debt agreements as of March 31, 2017 .
Loans under the Ciner Wyoming Credit Facility bear interest at Ciner Wyoming’s option at either:

•	a Base Rate, which 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 LIBOR plus 1.0%, in each case, plus an applicable margin; or	

•	a LIBOR Rate plus an applicable margin.	
The unused portion of the Ciner Wyoming Credit Facility is subject to an unused line fee ranging from 0.275% to 0.350% per annum based on Ciner Wyoming’s then current consolidated leverage ratio.
Revolving Credit Facility
On July 18, 2013, we entered into a $10.0 million senior secured revolving credit facility, as amended on October 30, 2014 (as amended, the “Revolving Credit Facility”), with a syndicate of lenders, which will mature on the fifth anniversary of the closing date of such credit facility. The Revolving Credit Facility provides for revolving loans to be available to fund distributions on the Partnership’s units and working capital requirements and capital expenditures, to consummate permitted acquisitions and for all other lawful partnership purposes. At March 31, 2017 , we had no outstanding borrowings under the Revolving Credit Facility. The Revolving Credit Facility includes a sublimit up to $5.0 million for same-day swing line advances and a sublimit up to $5.0 million for letters of credit. Our obligations under the Revolving Credit Facility are guaranteed by each of our material domestic subsidiaries other than Ciner Wyoming, and to the extent no material adverse tax consequences would result, foreign wholly-owned subsidiaries. As of March 31, 2017 , our only subsidiary was Ciner Wyoming. In addition, our obligations under the Revolving Credit Facility are secured by a pledge of substantially all of our assets (subject to certain exceptions), including the membership interests held in Ciner Wyoming by us.
On May 25, 2016, we entered into a Second Amendment to Credit Agreement, First Amendment to Notes, First Amendment to Security Agreement and First Amendment to Fee Letter (the “Ciner Resources Second Amendment”) with each of the lenders listed on the respective signature pages thereof and Bank of America, N.A., as administrative agent, swing line lender and L/C issuer. The Ciner Resources Second Amendment amends the Revolving Credit Facility.    
Among other things, the Ciner Resources Second Amendment (i) amends the Revolving Credit Facility by modifying the consolidated fixed charge coverage ratio (the ratio of consolidated cash flow to consolidated fixed charges, as defined in the Revolving Credit Facility) from not less than 1.10 to 1.00, prior to the Ciner Resources Second Amendment, to be not less than 1.00 to 1.00 as of the end of any fiscal quarter and (ii) prohibits financial institutions from European Economic Area member countries from serving as loan parties under the Revolving Credit Facility.
The Revolving Credit Facility contains various covenants and restrictive provisions that limit (subject to certain exceptions) our ability to (and the ability of our subsidiaries, including without limitation, Ciner Wyoming to):
• make distributions on or redeem or repurchase units;
• incur or guarantee additional debt;
• make certain investments and acquisitions;
• incur certain liens or permit them to exist;
• enter into certain types of transactions with affiliates;
• merge or consolidate with another company; and
• transfer, sell or otherwise dispose of assets.
The Revolving Credit Facility also requires quarterly maintenance of a consolidated fixed charge coverage ratio (as defined in the Revolving Credit Facility) of not less than 1.00 to 1.00. The Revolving Credit Facility also requires that consolidated capital expenditures, as defined in the Revolving Credit Facility, not exceed $50 million in any fiscal year.
In addition, the Revolving Credit Facility contains events of default customary for transactions of this nature, including (i) failure to make payments required under the Revolving Credit Facility, (ii) events of default resulting from failure to comply with covenants and financial ratios, (iii) the occurrence of a change of control, (iv) the institution of insolvency or similar proceedings against us or our material subsidiaries and (v) the occurrence of a default under any other material indebtedness we (or any of our subsidiaries) may have, including the Ciner Wyoming Credit Facility. Upon the occurrence and during the continuation of an event of default, subject to the terms and conditions of the Revolving Credit Facility, the lenders may terminate all outstanding commitments under the Revolving Credit Facility and may declare any outstanding principal of the Revolving Credit Facility debt, together with accrued and unpaid interest, to be immediately due and payable.
Under the Revolving Credit Facility, a change of control is triggered if Ciner Corp and its wholly-owned subsidiaries, directly or indirectly, cease to own all of the equity interests, or cease to have the ability to elect a majority of the board of directors (or similar governing body) of, Ciner Holdings or Ciner GP (or any entity that performs the functions of our general partner). In addition, a

27

change of control would be triggered if we cease to own at least 50.1% of the economic interests in Ciner Wyoming or ceases to have the ability to elect a majority of the members of Ciner Wyoming’s board of managers.
The Partnership was in compliance with all covenants and restrictions under its long-term debt agreements as of March 31, 2017 .
Loans under the Revolving Credit Facility bear interest at our option at either:

•	a Base Rate, which 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 LIBOR plus 1.0%, in each case, plus an applicable margin; or	

•	a LIBOR Rate plus an applicable margin.	
The unused portion of the Revolving Credit Facility is subject to an unused line fee ranging from 0.275% to 0.350% based on our then current consolidated leverage ratio.
Ciner Enterprises Credit Agreement     
In addition, there are restrictions in the Credit Agreement by and among Ciner Enterprises (as borrower), Ciner Holdings and Ciner Corp. (each as guarantors), and the lenders party thereto (as amended and restated or otherwise modified, the “Ciner Enterprises Credit Agreement”) that affect the Partnership. Specifically, Ciner Enterprises has agreed (subject to certain exceptions in addition to those described below) that it will not, and will not permit any of its subsidiaries, including Ciner Wyoming and us, to:

•	make distributions on or redeem or repurchase equity interests, other than distributions to our and Ciner Wyoming’s unitholders;	

•	incur or guarantee additional debt, other than debt incurred under the Revolving Credit Facility or the Ciner Wyoming Credit Facility, among certain other types of permitted debt;	

•	make certain investments and acquisitions, other than acquisitions by each of Ciner Wyoming and us, in an amount not to exceed $10 million and $2 million, respectively, and other exceptions set forth therein;	

•	incur certain liens or permit them to exist, other than, with respect to our and Ciner Wyoming’s liens, an aggregate amount outstanding at any time equal to $0.2 million and $1 million, respectively;	

•	enter into certain types of transaction with affiliates, other than transactions between Ciner Wyoming and us;	

•	merge or consolidate with another company; or	

•	transfer, sell or otherwise dispose of assets, other than our and Ciner Wyoming’s dispositions of assets with a net book value not to exceed $0.5 million and $2.5 million, respectively, in any given year.	
Contractual Obligations

During the three months ended March 31, 2017 , there were no material changes with respect to the contractual obligations disclosed in our Annual Report on Form 10-K for the year ended December 31, 2016 filed with the SEC on March 7, 2017 (the “2016 Annual Report”).
Off-Balance Sheet Arrangements
See Part I, Item 1, Financial Statements - Note 9 , Commitments and Contingencies - “Off-Balance Sheet Arrangements”, for additional details.
Critical Accounting Policies
During the three months ended March 31, 2017 , there were no material changes with respect to the critical accounting policies disclosed in our 2016 Annual Report.
Recently Issued Accounting Standards
Accounting standards recently issued are discussed in Item 1. Financial Statements - Note 1 , “Corporate Structure and Summary of Significant Accounting Policies”, in the notes to unaudited condensed consolidated financial statements.
Non-GAAP Financial Measures
We report our financial results in accordance with generally accepted accounting principles in the United States (“GAAP”). We also present the non-GAAP financial measures of:
• Adjusted EBITDA;

28

Table of Content

• distributable cash flow; and
• distribution coverage ratio.
We define Adjusted EBITDA as net income (loss) plus net interest expense, income tax, depreciation, depletion and amortization and certain other expenses that are non-cash charges or that we consider not to be indicative of ongoing operations. Distributable cash flow is defined as Adjusted EBITDA less net cash paid for interest, maintenance capital expenditures and income taxes, each as attributable to Ciner Resources LP. The Partnership may fund expansion-related capital expenditures with borrowings under existing credit facilities such that expansion-related capital expenditures will have no impact on cash on hand or the calculation of cash available for distribution.  In certain instances, the timing of the Partnership’s borrowings and/or its cash management practices will result in a mismatch between the period of the borrowing and the period of the capital expenditure.  In those instances, the Partnership adjusts designated reserves (as provided in the partnership agreement) to take account of the timing difference. Accordingly, expansion-related capital expenditures have been excluded from the presentation of cash available for distribution. Distributable cash flow will not reflect changes in working capital balances. We define distribution coverage ratio as the ratio of distributable cash flow as of the end of the period to cash distributions payable with respect to such period.
Adjusted EBITDA, distributable cash flow and distribution coverage ratio are non-GAAP supplemental financial measures that management and external users of our unaudited condensed consolidated financial statements, such as industry analysts, investors, lenders and rating agencies, may use to assess:

•	our operating performance as compared to other publicly traded partnerships in our industry, without regard to historical cost basis or, in the case of Adjusted EBITDA, financing methods;	

•	the ability of our assets to generate sufficient cash flow to make distributions to our unitholders;	

•	our ability to incur and service debt and fund capital expenditures; and	

•	the viability of capital expenditure projects and the returns on investment of various investment opportunities.	
We believe that the presentation of Adjusted EBITDA, distributable cash flow and distribution coverage ratio provide useful information to investors in assessing our financial condition and results of operations. The GAAP measures most directly comparable to Adjusted EBITDA and distributable cash flow are net income and net cash provided by operating activities. Our non-GAAP financial measures of Adjusted EBITDA, distributable cash flow and distribution coverage ratio should not be considered as alternatives to GAAP net income, operating income, net cash provided by operating activities, or any other measure of financial performance or liquidity presented in accordance with GAAP. Adjusted EBITDA and distributable cash flow have important limitations as analytical tools because they exclude some, but not all items that affect net income and net cash provided by operating activities. Investors should not consider Adjusted EBITDA, distributable cash flow and distribution coverage ratio in isolation or as a substitute for analysis of our results as reported under GAAP. Because Adjusted EBITDA, distributable cash flow and distribution coverage ratio may be defined differently by other companies, including those in our industry, our definition of Adjusted EBITDA, distributable cash flow and distribution coverage ratio may not be comparable to similarly titled measures of other companies, thereby diminishing its utility.
The table below presents a reconciliation of the non-GAAP financial measures of Adjusted EBITDA and distributable cash flow to the GAAP financial measures of net income and net cash provided by operating activities:

Item 3. Quantitative and Qualitative Disclosures about Market Risk
Our exposure to the financial markets consists of changes in interest rates relative to the balance of our outstanding debt obligations and derivatives that we have employed from time to time to manage our exposure to changes in market interest rates, and commodity prices. We do not use financial instruments or derivatives for trading or other speculative purposes. Our exposure to interest rate risks, and commodity price risks is discussed in Part II, Item 7A of our 2016 Annual Report. There has been no material change in that information.
Item 4. Controls and Procedures
Evaluation of Disclosure Controls and Procedures
Based on an evaluation of the effectiveness of the design and operation of disclosure controls and procedures, under the supervision and with the participation of the Partnership’s management, the Partnership’s principal executive officer and principal financial officer have concluded that the Partnership’s disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act were effective as of March 31, 2017 to ensure that information required to be disclosed by the Partnership in reports that it files or submits under the Exchange Act is (i) recorded, processed, summarized and reported within the time periods specified in the

30

Table of Content

Securities and Exchange Commission rules and forms and (ii) accumulated and communicated to the Partnership’s management, including its principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure.
Changes in Internal Control over Financial Reporting
There were no changes in the Partnership’s internal control over financial reporting during the quarter ended March 31, 2017 , which were identified in connection with management’s evaluation required by paragraph (d) of Rules 13a-15 and 15d-15 under the Exchange Act, that have materially affected, or are reasonably likely to materially affect, the Partnership’s internal control over financial reporting.

PART II. OTHER INFORMATION
Item 1. Legal Proceedings
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. Our legal proceedings are discussed in Part I, Item 3 of our 2016 Annual Report. There have been no material changes in that information.
Item 1A. Risk Factors
In addition to the information set forth in this Report, you should carefully consider the factors discussed in Part I, Item 1A. “Risk Factors” in our 2016 Annual Report, which could materially affect our business, financial condition or future results. During the three months ended March 31, 2017 , there were no material changes with respect to the risk factors disclosed in our 2016 Annual Report. The risks described in our 2016 Annual Report are not our only risks. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition and/or operating results.

Exhibit 95.1

MINE SAFETY DISCLOSURES

Section 1503 of the Dodd-Frank Wall Street Reform and Consumer Protection Act ("Dodd-Frank"), contains reporting requirements regarding coal or other mine safety. We operate a mine in conjunction with our Green River, Wyoming facility, which is subject to regulation by the Mine Safety and Health Administration (“MSHA”) under the Federal Mine Safety and Health Act of 1977 (the “Mine Act”), and is therefore subject to these reporting requirements. Presented in the table below is information regarding certain mining safety and health citations, orders and violations, if any, which MSHA has issued with respect to our operation as required by Dodd-Frank. In evaluating this information, consideration should be given to the fact that citations and orders can be contested and appealed, and in that process, may be reduced in severity, penalty amount or sometimes dismissed (vacated) altogether.
    
The letters used as column headings in the table below correspond to the explanations provided underneath the table as to the information set forth in each column with respect to the numbers of violations, orders, citations or dollar amounts, as the case may be, during the first calendar quarter of 2017 unless otherwise indicated. All section references in the table below refer to provisions of the Mine Act.
