CORPORATE STRUCTURE AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Corporate Structure and Summary of Significant Accounting Policies
1. CORPORATE STRUCTURE AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Nature of Operations

The unaudited condensed consolidated financial statements are composed of OCI Resources LP (the "Partnership," "OCI Resources," "OCIR," "we," "us," or "our"), a publicly traded Delaware limited partnership, and its consolidated subsidiary, OCI Wyoming LLC ("OCI Wyoming"), which is in the business of mining trona ore to produce soda ash. The Partnership's operations consist solely of its investment in OCI Wyoming. OCIR was formed in April 2013 by OCI Wyoming Holding Co. ("OCI Holdings"), a wholly-owned subsidiary of OCI Chemical Corporation ("OCI Chemical"). On September 18, 2013, the Partnership completed the initial public offering of its common units representing limited partner interests (the "Common Units"). The Partnership owns a controlling interest comprised of 51.0% membership interest in OCI Wyoming. All soda ash processed is sold to various domestic, Korean and European customers and to American Natural Soda Ash Corporation ("ANSAC") which is an affiliate for export. 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 June 30, 2015 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, 2014 (the "2014 Annual Report"). There has been no material change in the significant accounting policies followed by us during the six month periods ended June 30, 2015 from those disclosed in the 2014 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 OCI 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 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. In July 2015, FASB decided to delay the effective date of the new revenue recognition standard by one year. As a result, public entities will apply the new revenue standard to annual reporting periods beginning after December 15, 2017 and interim periods therein and will require expanded disclosures. Early adoption of the new revenue standard is allowed, however, entities are not permitted to adopt the standard earlier than the original effective date (annual reporting periods beginning on or after December 15, 2016 and interim periods therein). We are currently assessing the impact the adoption of ASU 2014-09 will have on our condensed consolidated financial statements, as well as the available transition methods.
In June 2014, the FASB issued ASU No. 2014-12, Compensation – Stock Compensation (Topic 718): Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period. The new guidance requires that share-based compensation that require a specific performance target to be achieved in order for employees to become eligible to vest in the awards and that could be achieved after an employee completes the requisite service period be treated as a performance condition. As such, the performance target should not be reflected in estimating the grant-date fair value of the award. Compensation costs should be recognized in the period in which it becomes probable that the performance target will be achieved and should represent the compensation cost attributable to the period(s) for which the requisite service has already been rendered. If the performance target becomes probable of being achieved before the end of the requisite service period, the remaining unrecognized compensation cost should be recognized prospectively over the remaining requisite service period. The total amount of compensation cost recognized during and after the requisite service period should reflect the number of awards that are expected to vest and should be adjusted to reflect those awards that ultimately vest. The requisite service period ends when the employee can cease rendering service and still be eligible to vest in the award if the performance target is achieved. This new guidance is effective for fiscal years and interim periods within those years beginning after December 15, 2015. Early adoption is permitted. Entities may apply the amendments in this Update either (a) prospectively to all awards granted or modified after the effective date or (b) retrospectively to all awards with performance targets that are outstanding as of the beginning of the earliest annual period presented in the financial statements and to all new or modified awards thereafter. The adoption of ASU 2014-12 has not had a material impact on our financial position or results of operations.
In April 2015, the FASB issued ASU No. 2015-03, Simplifying the Presentation of Debt Issuance Costs ("ASU 2015-03"), which requires debt issuance costs to be presented in the balance sheet as a direct deduction from the carrying value of associated debt liability, consistent with the presentation of a debt discount, rather than being presented as an asset. Amortization of debt issuance costs will continue to be reported as interest expense. ASU 2015-03 is effective for fiscal years and interim periods within those years beginning after December 15, 2015, and requires retrospective application for each prior period presented. Early adoption is permitted for financial statements that have not been previously issued. The Partnership is currently evaluating the potential impact of this standard on its 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) is computed by dividing limited partners’ interest in net income attributable to OCI Resources LP, after deducting the general partner's interest and any incentive distributions, by the weighted average number of outstanding common and subordinated units. 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, 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. Basic and diluted net income per unit applicable to limited partners were the same as our potentially dilutive units outstanding were immaterial and we had no anti-dilutive units for the three and six months ended June 30, 2015. For the three and six months ended June 30, 2014, we did not have any potentially dilutive units outstanding.
The net income attributable to common and subordinated unitholders and the weighted average units for calculating basic and diluted net income per common and subordinated units were as follows:

Quarterly Distribution
On July 17, 2015, the Partnership declared its second quarter 2015 quarterly cash distribution of $0.5445 per unit. The quarterly cash distribution is payable on August 14, 2015 to unitholders of record on July 31, 2015.
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.
Distributions from Operating Surplus During the Subordination Period
If we make a distribution from operating surplus for any quarter during the subordination period, our partnership agreement requires that we make the distribution in the following manner:
•
first, 98.0% to the common unitholders, pro rata, and 2.0% to our general partner, until we distribute for each common unit an amount equal to the minimum quarterly distribution for that quarter;
•
second, 98.0% to the common unitholders, pro rata, and 2.0% to our general partner, until we distribute for each outstanding common unit an amount equal to any arrearages in the payment of the minimum quarterly distribution on the common units with respect to any prior quarters;
•
third, 98.0% to the subordinated unitholders, pro rata, and 2.0% to our general partner, until we distribute for each subordinated unit an amount equal to the minimum quarterly distribution for that quarter; and
•
thereafter, in the manner described in "General Partner Interest and Incentive Distribution Rights" below.
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.

Subsequent to the issuance of the Partnership’s consolidated financial statements for the year ended December 31, 2014, the Partnership identified a balance sheet misclassification relating to the portion of stores inventory that is not reasonably expected to be used during the year. That amount was presented as a component of inventory (a current asset) rather than as a non-current asset in the December 31, 2014 balance sheet. The correction of this error resulted in a decrease of current assets and inventory and a corresponding increase in other non-current assets of $20.7 million. The result of this correction did not impact the Partnership’s consolidated statements of income, comprehensive income, equity, and cash flows for any period presented. Management does not believe this misstatement is individually or collectively material to the consolidated financial statements.

Demand Revenue Bonds
The above revenue bonds require OCI Wyoming to maintain standby letters of credit totaling $20.3 million at June 30, 2015 and December 31, 2014, respectively. These letters of credit require compliance with certain covenants, including minimum net worth, maximum debt to net worth, and interest coverage ratios. As of June 30, 2015 and December 31, 2014, OCI Wyoming was in compliance with these debt covenants.
OCI Wyoming Credit Facility
On July 18, 2013, OCI Wyoming entered into a $190.0 million senior unsecured revolving credit facility, as amended on October 30, 2014 (as amended, the "OCI Wyoming Credit Facility"), with a syndicate of lenders, which will mature on the fifth anniversary of the closing date of such credit facility. The OCI 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 OCI Wyoming Credit Facility has an accordion feature that allows OCI Wyoming to increase the available revolving borrowings under the facility by up to an additional $75.0 million, subject to OCI Wyoming receiving increased commitments from existing lenders or new commitments from new lenders and the satisfaction of certain other conditions. In addition, the OCI 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. OCI Wyoming's obligations under the OCI Wyoming Credit Facility are unsecured.
The OCI Wyoming Credit Facility contains various covenants and restrictive provisions that limit (subject to certain exceptions) OCI 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 OCI Wyoming;
•
merge or consolidate with another company; and
•
transfer, sell or otherwise dispose of assets.
The OCI Wyoming Credit Facility also requires quarterly maintenance of a consolidated leverage ratio (as defined in the OCI Wyoming Credit Facility) of not more than 3.00 to 1.00 and a consolidated fixed charge coverage ratio (as defined in the OCI Wyoming Credit Facility) of not less than 1.10 to 1.00 for the 2015 fiscal year and not less than 1.15 to 1.00 thereafter. The OCI Wyoming Credit Facility also requires that consolidated capital expenditures, as defined in the OCI Wyoming Credit Facility, not exceed $50 million in any fiscal year.
In addition, the OCI Wyoming Credit Facility contains events of default customary for transactions of this nature, including (i) failure to make payments required under the OCI Wyoming Credit Facility, (ii) events of default resulting from failure to comply with covenants and financial ratios in the OCI Wyoming Credit Facility, (iii) the occurrence of a change of control, (iv) the institution of insolvency or similar proceedings against OCI Wyoming and (v) the occurrence of a default under any other material indebtedness OCI Wyoming may have. Upon the occurrence and during the continuation of an event of default, subject to the terms and conditions of the OCI Wyoming Credit Facility, the lenders may terminate all outstanding commitments under the OCI Wyoming Credit Facility and may declare any outstanding principal of the OCI Wyoming Credit Facility debt, together with accrued and unpaid interest, to be immediately due and payable.
Under the OCI Wyoming Credit Facility, a change of control is triggered if OCI Chemical 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 OCI 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 OCI Wyoming or cease to have the ability to elect a majority of the members of OCI Wyoming's board of managers.
OCI Wyoming was in compliance with all covenants and restrictions under its long-term debt agreements as of June 30, 2015.
Loans under the OCI Wyoming Credit Facility bear interest at OCI 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 and (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 OCI Wyoming Credit Facility is subject to an unused line fee ranging from 0.275% to 0.350% per annum based on OCI 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 OCIR's units and working capital requirements and capital expenditures, to consummate permitted acquisitions and for all other lawful partnership purposes. At June 30, 2015, 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 OCI Wyoming, and to the extent no material adverse tax consequences would result, foreign wholly-owned subsidiaries. As of June 30, 2015, our only subsidiary was OCI 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 partnership interests held in OCI Wyoming by us.

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, OCI 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 1.05 to 1.00 for the 2015 fiscal year and not less than 1.10 to 1.00 thereafter. 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 OCI 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 OCI Chemical 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, OCI Holdings or OCI 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 OCI Wyoming or ceases to have the ability to elect a majority of the members of OCI Wyoming's board of managers.
The Partnership was in compliance with all covenants and restrictions under its long-term debt agreements as of June 30, 2015.

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 and (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.

EMPLOYEE COMPENSATION
EMPLOYEE COMPENSATION
EMPLOYEE COMPENSATION

The Partnership participates in various benefit plans offered and administered by OCI Enterprises and is allocated its portions of the annual costs related thereto. The specific plans are as follows:
Retirement Plans - Benefits provided under the OCI Enterprises' Pension Plan for Salaried Employees and OCI Enterprises' Pension Plan for Hourly Employees 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. OCI Enterprises’ 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 OCI Enterprises’ net periodic pension costs were expense of $2.2 million and income of $0.1 million for the three months ended June 30, 2015 and 2014, respectively and expense of $4.4 million and $1.6 million for the six months ended June 30, 2015 and 2014, respectively. The increase in pension costs during 2015 of $2.3 million and $2.8 million for three and six months ended June 30, 2015, respectively, was driven by unfavorable effects of lower actuarial discount rates and market return assumptions in 2015 versus 2014.
Savings Plan - The OCI Enterprises' 401(k) Retirement 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 by OCI Enterprises for the three months ended June 30, 2015 and 2014, were $0.4 million and $0.5 million, respectively and $0.8 million and $1.0 million for the six months ended June 30, 2015 and 2014, respectively.
Postretirement Benefits - Most of the Partnership's employees are eligible for postretirement benefits other than pensions if they reach retirement age while still employed.
OCI Enterprises accounts for postretirement benefits on an accrual basis over an employee’s period of service. The postretirement plan, excluding pensions, are not funded, and OCI Enterprises has the right to modify or terminate the plan. OCI Enterprises' post-retirement benefits had a benefits obligation of $22.2 million and $22.8 million at June 30, 2015 and December 31, 2014, respectively. Effective January 1, 2013, the postretirement benefits for non-grandfathered retirees were amended to replace the medical coverage for post-65-year-old members with a fixed dollar contribution amount. As a result of the amendment, the accumulated and projected benefit obligation for postretirement benefits decreased by $8.7 million and resulted in a prior service credit of $7.7 million, which is being recognized as a reduction of net periodic postretirement benefit costs in future years. The Partnership’s allocated portion of postretirement benefit costs were expense of $0.1 million and $0.0 million for the three months ended June 30, 2015 and 2014, respectively and expense of $0.3 million and income of $0.1 million for the six months ended June 30, 2015 and 2014, respectively.
EQUITY - BASED COMPENSATION (Notes)
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 Annual Report on Form 10-K for the year ended December 31, 2014.
All employees, officers, consultants and non-employee directors of us and our parents and subsidiaries are eligible to be selected to participate in the OCI Resource Partners LLC 2013 Long-Term Incentive Plan (the "Plan" or "LTIP"). As of June 30, 2015, subject to further adjustment as provided in the Plan, a total of 908,688 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, any common units counted against the number of common units available for issuance pursuant to the Plan with respect to such award will again be available for awards under the Plan.
Non-employee Director Awards
During the six months ended June 30, 2015, a total of 11,064 common units were granted and fully vested to non-employee directors, and 6,450 during the six months ended June 30, 2014. The grant date average fair value per unit of these awards was $22.54 and $21.69 for six months ended June 30, 2015 and 2014, respectively. The total fair value of these awards were approximately $0.2 million and $0.1 million during the six months ended June 30, 2015 and 2014, respectively.

Time Restricted Unit Awards
We grant restricted unit awards in the form of common units to certain of our executive officers 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. During the six months ended June 30, 2014, we had no time restricted unit awards granted.
The following table presents a summary of activity on the Time Restricted Unit Awards:

(1) Determined by dividing the aggregate grant date fair value of awards by the number of awards issued. No estimated forfeiture rate was applied to the awards as of June 30, 2015, as all awards granted are expected to vest.
Total Return Performance Unit Awards
We grant TR Performance Unit Awards to certain of our executive officers. 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. During the six months ended June 30, 2014, we had no TR Performance Unit Awards granted.
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, which requires 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
COMMITMENTS AND CONTINGENCIES
COMMITMENTS AND CONTINGENCIES
From time to time, the Partnership has various litigation, claims and assessments that arise in the normal course of business. Management does not believe, based upon its evaluation and discussion with counsel, that the ultimate outcome of any current matters, individually or in the aggregate, would have a material effect on the Partnership's financial position, results of operations or cash flows.
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. As of June 30, 2015 and December 31, 2014, the amount of the bond was $33.9 million, respectively, 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.

OCI Wyoming's revenue bonds require it to maintain stand-by letters of credit totaling $20.3 million as of June 30, 2015.

AGREEMENTS AND TRANSACTIONS WITH AFFILIATES
OCI Chemical is the exclusive sales agent for the Partnership and through its membership in ANSAC. OCI Chemical 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 OCI Chemical are charged directly to the Partnership. Selling, general and administrative expenses also include amounts charged to the Partnership by OCI Enterprises and OCI Chemical principally consisting of salaries, benefits, office supplies, professional fees, travel, rent and other costs of certain assets used by the Partnership. These transactions 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 OCI Enterprises and OCI Chemical, including ANSAC related charges were as follows:

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.

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, accrued expenses and long-term debt. The carrying amounts of cash and cash equivalents, accounts receivable, accounts payable and accrued expenses 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, designed 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 generally will mature on July 18, 2018, the maturity date of the long-term debt under the OCI Wyoming Credit Facility. These contracts had an aggregate notional value of $75.0 million and a fair value liability of $1.1 million as of June 30, 2015 (December 31, 2014: notional value of $76.0 million; fair value liability of $0.7 million).
We enter into foreign exchange forward contracts to reduce certain firm commitments denominated in currencies other than the U.S. dollar. However, the Partnership does not apply hedge accounting for these contracts. These contracts are for periods consistent with the exposure being hedged and generally have maturities of one year or less. The forward contracts, which are predominantly used to purchase U.S. dollars and sell Euros, had a fair value asset of $0.1 million and $0.6 million at June 30, 2015 and December 31, 2014, respectively. These currency hedges had an aggregate notional value of $13.8 million and $6.9 million at June 30, 2015 and December 31, 2014, respectively.
We enter into natural gas forward contracts, designed as cash flow hedges, to mitigate volatility in the price of certain of the natural gas we consume. These contracts have maturities ranging from 2015 to 2020. The fair value of these contracts as of June 30, 2015, had an aggregate notional value of $16.8 million and a fair value liability of $1.3 million, of which $0.9 million represents the non-current fair value liability portion. We had no similar contracts outstanding as of December 31, 2014.

Financial Assets and Liabilities not Measured at Fair Value
The fair value of our long-term debt is based on present rates for indebtedness with similar amounts, durations and credit risks. See Note 4 "Debt" for additional information on our debt arrangements.

CORPORATE STRUCTURE AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)
Basis of Presentation and Significant Accounting Policies 
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 June 30, 2015 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, 2014 (the "2014 Annual Report"). There has been no material change in the significant accounting policies followed by us during the six month periods ended June 30, 2015 from those disclosed in the 2014 Annual Report.

Use of Estimates 
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.

We have evaluated subsequent events through the filing of this Quarterly Report on Form 10-Q.
Recently Issued Accounting Pronouncements 
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. In July 2015, FASB decided to delay the effective date of the new revenue recognition standard by one year. As a result, public entities will apply the new revenue standard to annual reporting periods beginning after December 15, 2017 and interim periods therein and will require expanded disclosures. Early adoption of the new revenue standard is allowed, however, entities are not permitted to adopt the standard earlier than the original effective date (annual reporting periods beginning on or after December 15, 2016 and interim periods therein). We are currently assessing the impact the adoption of ASU 2014-09 will have on our condensed consolidated financial statements, as well as the available transition methods.
In June 2014, the FASB issued ASU No. 2014-12, Compensation – Stock Compensation (Topic 718): Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period. The new guidance requires that share-based compensation that require a specific performance target to be achieved in order for employees to become eligible to vest in the awards and that could be achieved after an employee completes the requisite service period be treated as a performance condition. As such, the performance target should not be reflected in estimating the grant-date fair value of the award. Compensation costs should be recognized in the period in which it becomes probable that the performance target will be achieved and should represent the compensation cost attributable to the period(s) for which the requisite service has already been rendered. If the performance target becomes probable of being achieved before the end of the requisite service period, the remaining unrecognized compensation cost should be recognized prospectively over the remaining requisite service period. The total amount of compensation cost recognized during and after the requisite service period should reflect the number of awards that are expected to vest and should be adjusted to reflect those awards that ultimately vest. The requisite service period ends when the employee can cease rendering service and still be eligible to vest in the award if the performance target is achieved. This new guidance is effective for fiscal years and interim periods within those years beginning after December 15, 2015. Early adoption is permitted. Entities may apply the amendments in this Update either (a) prospectively to all awards granted or modified after the effective date or (b) retrospectively to all awards with performance targets that are outstanding as of the beginning of the earliest annual period presented in the financial statements and to all new or modified awards thereafter. The adoption of ASU 2014-12 has not had a material impact on our financial position or results of operations.
In April 2015, the FASB issued ASU No. 2015-03, Simplifying the Presentation of Debt Issuance Costs ("ASU 2015-03"), which requires debt issuance costs to be presented in the balance sheet as a direct deduction from the carrying value of associated debt liability, consistent with the presentation of a debt discount, rather than being presented as an asset. Amortization of debt issuance costs will continue to be reported as interest expense. ASU 2015-03 is effective for fiscal years and interim periods within those years beginning after December 15, 2015, and requires retrospective application for each prior period presented. Early adoption is permitted for financial statements that have not been previously issued. The Partnership is currently evaluating the potential impact of this standard on its condensed consolidated financial statements.

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.
