In April 2015, NRP announced a strategic plan to reduce our debt and strengthen  

our balance sheet. We have worked diligently since then and much of what we  

accomplished occurred in 2017. Since the April 2015 announcement, we have: 

•  reduced our debt by more than 40%, or $634 million; 

•  lowered our debt-to-EBITDA ratio from a high of 5.3x to 3.6x; 

•  extended the maturities of over $575 million of debt that would have matured in 2018 

out to 2020 and 2022; 

•  brought in equity partners who made a $250 million preferred equity investment in us; 

•  managed our business with internally generated cash flow and reduced costs across 

all of our business segments; and

•  continued to pay distributions on our common units and maintain a strong distribution 

coverage ratio. 

We continue to execute on the goals announced three years ago and remain committed 

to creating long-term value for our stakeholders by de-risking our capital structure.

Our Operations

We continue to benefit from the royalty nature of our coal business, which generated 

substantial cash flow in 2017. Our diversified portfolio includes a mix of metallurgical  

and thermal coal reserves that can be leveraged to take advantage of market cycles. 

Metallurgical coal prices remained well above the lows seen in 2016 due to stronger 

export demand and steel industry fundamentals. Reductions in domestic utility coal 

stockpiles and a robust export market helped sustain thermal coal prices during the year. 

“ We continue to execute on the goals  
announced three years ago and remain  
committed to creating long-term value  
for our stakeholders by de-risking our  
capital structure.”

“ Our actions over the last 
three years and solid 2017 
results demonstrate our 
dedication to our long-
term strategy.”

Our 49% interest in the Ciner Wyoming trona mine and soda ash production business 

continues to perform well and paid close to $50 million in cash distributions to us in 

2017. This business is one of the largest and lowest cost natural soda ash producers  

in the world and is well positioned for the future.

Our construction aggregates business consists of four separate operations from  

Louisiana to Pennsylvania that have long-life reserves and strong positions in the local 

markets they serve. The business posted solid results during 2017 despite continued 

reduced demand at the largest of the four operations, which supplies materials to  

natural gas producers in West Virginia and Pennsylvania.

Looking Ahead

Our assets continue to perform well and our financial condition is sound. While the 

abundance of low-cost natural gas will continue to affect demand for thermal coal by 

power generating facilities, our substantial metallurgical coal reserves position us well 

for the future. We will maintain our focus on strengthening our balance sheet and  

maximizing the intrinsic value of our assets. Our actions over the last three years and 

solid 2017 results demonstrate our dedication to our long-term strategy, and we thank  

all of our stakeholders for their continued support of NRP. With 35% of the outstanding 

common units owned by insiders, management’s interests are closely aligned with  

all stakeholders.

ITEMS 1. AND 2.  BUSINESS AND PROPERTIES 

Partnership Structure and Management

We are a publicly traded Delaware limited partnership formed in 2002. We own, operate, manage and lease a diversified 
portfolio of mineral properties in the United States, including interests in coal, trona and soda ash, construction aggregates and 
other natural resources. Our business is organized into three operating segments:

Coal Royalty and Other—consists primarily of coal royalty properties and coal-related transportation and processing assets. 
Other assets include aggregates royalty, industrial mineral royalty, oil and gas royalty and timber. Our coal reserves are primarily 
located in Appalachia, the Illinois Basin and the Western United States. Our aggregates and industrial minerals properties are 
located in a number of states across the United States. Our oil and gas royalty assets are primarily located in Louisiana.    

Soda Ash—consists of our 49% non-controlling equity interest in a trona ore mining operation and soda ash refinery in the 
Green River Basin, Wyoming. We recognize our portion of equity earnings and receive regular quarterly distributions from this 
business. 

Construction Aggregates—consists of our construction materials business that operates hard rock quarries, an underground 
limestone mine, sand and gravel plants, asphalt plants and marine terminals. Our construction aggregates business operates in 
Pennsylvania, West Virginia, Tennessee, Kentucky and Louisiana.  

Our operations are conducted through Opco, and our operating assets are owned by our subsidiaries. NRP (GP) LP, our 
general partner, has sole responsibility for conducting our business and for managing our operations. Because our general partner 
is a limited partnership, its general partner, GP Natural Resource Partners LLC, conducts its business and operations, and the Board 
of Directors and officers of GP Natural Resource Partners LLC make decisions on our behalf. Robertson Coal Management LLC, 
a limited liability company wholly owned by Corbin J. Robertson, Jr., owns all of the membership interest in GP Natural Resource 
Partners LLC. Subject to the Board Representation and Observation Rights Agreement with certain entities controlled by funds 
affiliated with The Blackstone Group, L.P. (collectively referred to as "Blackstone") and affiliates of GoldenTree Asset Management 
LP (collectively referred to as "GoldenTree"), Mr. Robertson, Jr. is entitled to appoint the members of the Board of Directors of

2017 Recapitalization Transactions and Debt Reduction 

During the first quarter of 2017, we completed recapitalization transactions that improved our liquidity and strengthened 
our balance sheet. These recapitalization transactions included the issuance of $250 million of Class A Preferred Units and Warrants 
to purchase Common Units, and the extension of the majority of our 2018 debt maturities to 2020 and 2022. For more information 
on these transactions, see Note 3. Class A Convertible Preferred Units and Warrants and Note 13. Debt in the Notes to Consolidated 
Financial Statements under Item 8 in this Annual Report on Form 10-K, which is incorporated herein by reference.   

During 2017, we reduced our debt by $311.1 million. See "Liquidity and Capital Resources" below for additional information 
on our debt reduction. We remain focused on further reducing our debt and improving our credit metrics and creating long-term 
value for our stakeholders.

We own coal reserves in the three major producing regions of the United States: the Appalachia Basin, the Illinois Basin, the 
Powder River Basin and the Gulf Coast. We do not operate any coal mines, but lease our reserves to experienced mine operators 
under  long-term  leases  that  grant  the  operators  the  right  to  mine  and  sell  our  reserves  in  exchange  for  royalty  payments. 
Approximately two-thirds of our leases have a term between five to forty years, with many leases having an option by the operators 
to extend the lease for additional terms. Leases may include the right to renegotiate rents and royalties for the extended term. We 
also own and manage coal-related infrastructure assets that generate additional revenues in the Illinois Basin. In addition, we own 
aggregates and industrial mineral reserves located in a number of states across the country. As described in the "Other Assets" 
section below, we also own natural gas, aggregate and industrial mineral reserves that generate a small portion of coal royalty and 
other segment revenues. 

Under our standard lease, lessees calculate royalty payments due to us and are required to report tons of minerals removed 
as well as the sales prices of the extracted minerals. Therefore, to a great extent, amounts reported as royalty revenue are based 
upon the reports of our lessees. We periodically audit this information by examining certain records and internal reports of our 
lessees, and we perform periodic mine inspections to verify that the information that our lessees have submitted to us is accurate. 
Our audit and inspection processes are designed to identify material variances from lease terms as well as differences between the 
information reported to us and the actual results from each property.

In addition to their royalty obligations, our lessees are often subject to pre-established minimum quarterly or annual payments. 
These minimum rentals reflect amounts we are entitled to receive even if no mining activity occurred during the period. Minimum 
rentals are usually credited against future royalties that are earned as minerals are produced. Typically, the lessee is time limited 
on the period available for recouping minimum rentals. 

2

Because we do not operate any coal mines, our coal royalty business does not bear ordinary operating costs and has limited 
direct exposure to environmental, permitting and labor risks. Our lessees, as operators, are subject to environmental laws, permitting 
requirements and other regulations adopted by various governmental authorities. In addition, the lessees generally bear all labor-
related  risks,  including  retiree  health  care  legacy  costs,  black  lung  benefits  and  workers’  compensation  costs  associated  with 
operating the mines on our coal and aggregates properties. We typically pay property taxes on our properties, which are largely 
reimbursed by our lessees pursuant to the terms of the various lease agreements.

(1)  For purposes of this table, we have defined metallurgical coal reserves as reserves located in seams that historically have 
been of sufficient quality and characteristics to be able to be used in the steel making process. Some of the reserves in the 
metallurgical category can also be used as thermal coal. In 2017, approximately 58% of our coal royalty revenues and 
approximately 45% of the related production came from production of metallurgical coal.

(1)  Unless otherwise indicated, the coal quality information in this Annual Report and on the Form 10-K is reported on an as-
received basis with an assumed moisture of 6% for Appalachian reserves, and site specific moisture values for Illinois 
(typically 12% moisture) and Northern Powder River Basin (typically 25% moisture).

(2)  Compliance coal, when burned, emits less than 1.2 pounds of sulfur dioxide per million Btu and meets the sulfur dioxide 
emission standards imposed by Phase II of the Clean Air Act without blending with other coals or using sulfur dioxide 
reduction technologies. Compliance coal is a subset of low sulfur coal and is, therefore, also reported within the amounts 
for low sulfur coal.

Methodologies Used in Mineral Reserve Estimation

All of the reserves reported above are recoverable proven or probable reserves as determined by the SEC’s Industry Guide 
7 and are estimated by our internal reserve geologist. The technologies and economic data used by our internal reserve geologist 
in the estimation of our proven or probable reserves include, but are not limited to, drill logs, geophysical logs, geologic maps 
including  isopach,  mine,  and  coal  quality,  cross  sections,  statistical  analysis,  and  available  public  production  data. There  are 
numerous uncertainties inherent in estimating the quantities and qualities of recoverable reserves, including many factors beyond 
our control. Estimates of economically recoverable coal reserves depend upon a number of variable factors and assumptions, any 
one of which may, if incorrect, result in an estimate that varies considerably from actual results. See "Item 1A. Risk Factors—
Risks Related to Our Business—Our reserve estimates depend on many assumptions that may be inaccurate, which could materially 
adversely affect the quantities and value of our reserves."

Coal Transportation and Processing Assets

We own transportation and processing infrastructure related to certain of our coal properties and recorded $20.5 million in 
revenue related to these assets during the year ended December 31, 2017. We own loadout and other transportation assets at the 
Williamson and Macoupin mines in the Illinois Basin. In addition, we own rail loadout and associated infrastructure at the Sugar 
Camp mine, an Illinois Basin mine also operated by a subsidiary of Foresight Energy. While we own coal reserves at the Williamson 
and Macoupin mines, we do not own coal reserves at the Sugar Camp mine. We typically lease this infrastructure to third parties 
and collect throughput fees; however, at the loadout facility at the Williamson mine, we operate the coal handling and transportation 
infrastructure and have subcontracted out that responsibility to a third party. 

Other Assets 

As of December 31, 2017, we owned an estimated 174 million tons of aggregates reserves primarily located in Kentucky 
and Indiana. We lease a portion of these reserves to third parties in exchange for royalty payments. Of the 174 million tons owned, 
we lease approximately 108 million tons of these reserves to our Construction Aggregates Grand Rivers operation. In addition, 
we hold an override royalty interest in frac sand opportunities in Wisconsin and Texas and an override royalty interest in sand and 
gravel in Washington. The override royalty interests total approximately 101 million tons. The structure of these leases is similar 
to our coal leases, and these leases typically also require minimum rental payments in addition to royalties. During 2017, our 
aggregates lessees produced 4.4 million tons of aggregates from these properties and we received $4.2 million in aggregates royalty 
revenues, including overriding royalty revenues. 

Through our 51% ownership of BRP LLC ("BRP"), a joint venture with International Paper Company, we own approximately 

10 million mineral acres in 31 states that include the following assets:

• 

• 

• 

• 

• 

• 

approximately 300,000 gross acres of oil and natural gas mineral rights in Louisiana, of which over 53,000 acres were 
leased as of December 31, 2017; 

approximately 50 million tons of aggregate reserves primarily located in Arkansas, North Carolina and South Carolina 
and approximately 16 million tons of override royalty interest in North Carolina and Georgia;

approximately 95,000 net mineral acres of coal rights (primarily lignite and some bituminous coal) in the Gulf Coast 
region, of which approximately 5,600 acres are leased in Louisiana, Mississippi and Texas;

an overriding royalty interest of 1% on approximately 25,000 mineral acres in Louisiana;

copper rights in Michigan’s Upper Peninsula that are subject to a development agreement with a copper development 
company; and

various other mineral rights including coalbed methane, metals, aggregates, water and geothermal, in several states 
throughout the United States. 

While the vast majority of the 10 million acres remain largely undeveloped, BRP has an ongoing program to identify additional 

opportunities to lease its minerals to operating parties.

Soda Ash Segment 

We own a 49% non-controlling equity interest in Ciner Wyoming. Ciner Resources LP, our operating partner, controls and 
operates  Ciner Wyoming.  Ciner  Resources  LP  mines  the  trona,  processes  it  into  soda  ash,  and  distributes  the  soda  ash  both 
domestically and internationally into the glass and chemicals industries.  Ciner Resources LP is a publicly traded master limited 
partnership that depends on distributions from Ciner Wyoming in order to make distributions to its public unitholders. 

 Ciner Wyoming is one of the largest and lowest cost producers of soda ash in the world, serving a global market from its 
facility located in the Green River Basin of Wyoming. The Green River Basin geological formation holds the largest, and one of 
the highest purity, known deposits of trona ore in the world. Trona, a naturally occurring soft mineral, is also known as sodium 
sesquicarbonate and consists primarily of sodium carbonate, or soda ash, sodium bicarbonate and water. Ciner Wyoming processes 
trona ore into soda ash, which is an essential raw material in flat glass, container glass, detergents, chemicals, paper and other 
consumer and industrial products. The vast majority of the world’s accessible trona reserves are located in the Green River Basin. 
According to historical production statistics, approximately one-quarter of global soda ash is produced by processing trona, with 
the remainder being produced synthetically through chemical processes. The costs associated with procuring the materials needed 
for synthetic production are greater than the costs associated with mining trona for trona-based production. In addition, trona-
based production consumes less energy and produces fewer undesirable by-products than synthetic production.

Ciner Wyoming’s Green River Basin surface operations are situated on approximately 880 acres in Wyoming, and its mining 
operations consist of approximately 23,500 acres of leased and licensed subsurface mining area. The facility is accessible by both 
road and rail. Ciner Wyoming uses seven large continuous mining machines and 14 underground shuttle cars in its mining operations. 
Its  processing  assets  consist  of  material  sizing  units,  conveyors,  calciners,  dissolver  circuits,  thickener  tanks,  drum  filters, 
evaporators and rotary dryers. The following map provides an aerial overview of Ciner Wyoming’s surface operations:

14

In trona ore processing, insoluble materials and other impurities are removed by thickening and filtering the liquor, a solution 
consisting of sodium carbonate dissolved in water. Ciner Wyoming then adds activated carbon to filters to remove organic impurities, 
which can cause color contamination in the final product. The resulting clear liquid is then crystallized in evaporators, producing 
sodium carbonate monohydrate. The crystals are then drawn off and passed through a centrifuge to remove excess water. The 
resulting material is dried in a product dryer to form anhydrous sodium carbonate, or soda ash. The resulting processed soda ash 
is then stored in on-site storage silos to await shipment by bulk rail or truck to distributors and end customers. Ciner Wyoming’s 
storage silos can hold up to 65,000 short tons of processed soda ash at any given time. The facility is in good working condition 
and has been in service for over 50 years.

Deca Rehydration.  The evaporation stage of trona ore processing produces a precipitate and natural by-product called deca. 
"Deca," short for sodium carbonate decahydrate, is one part soda ash and ten parts water. Solar evaporation causes deca to crystallize 
and precipitate to the bottom of the four main surface ponds at the Green River Basin facility. The deca rehydration process enables 
Ciner Wyoming to recover soda ash from the deca-rich purged liquor as a by-product of the refining process. The soda ash contained 
in deca is captured by allowing the deca crystals to evaporate in the sun and separating the dehydrated crystals from the soda ash. 
15

The separated deca crystals are then blended with partially processed trona ore in the dissolving stage of the production process. 
This process enables Ciner Wyoming to reduce waste storage needs and convert what is typically a waste product into a usable 
raw material. As a result of this process, Ciner Wyoming has been able to reduce the amount of short tons of trona ore it takes to 
produce one short ton of soda ash.

Shipping and Logistics.  All of the soda ash produced is shipped by rail or truck from the Green River Basin facility. Ciner 
Wyoming leases a fleet of more than 2,000 hopper cars that serve as dedicated modes of shipment to its domestic customers. For 
export, Ciner Wyoming ships soda ash on unit trains consisting of approximately 100 cars to two primary ports: Port Arthur, Texas 
and Portland, Oregon. From these ports, the soda ash is loaded onto ships for delivery to ports all over the world. American Natural 
Soda Ash Corporation ("ANSAC") provides logistics and support services for all of Ciner Wyoming’s export sales. For domestic 
sales, Ciner Resources Corporation provides similar services.

Customers.  Ciner Wyoming’s largest customer is ANSAC, which buys soda ash (through Ciner Wyoming’s sales agent) and 
other of its member companies for further export to its customers. ANSAC accounted for approximately 45% of Ciner Wyoming’s 
net sales in 2017. ANSAC takes soda ash orders directly from its overseas customers and then purchases soda ash for resale from 
its member companies pro rata based on each member’s production volumes. ANSAC is the exclusive distributor for its members 
to the markets it serves. However, Ciner Resources Corporation, on Ciner Wyoming’s behalf, negotiates directly with, and Ciner 
Wyoming exports to, customers in markets not served by ANSAC. During 2017, approximately 27% of Ciner Wyoming’s net sales 
were to an affiliate of Ciner Resources Corporation that sold soda ash into international markets not served by ANSAC. During 
2017, Ciner Wyoming had approximately 70 domestic customers.

Leases and License.  Ciner Wyoming is party to several mining leases and one license for its subsurface mining rights. Some 
of the leases are renewable at Ciner Wyoming’s option upon expiration. Ciner Wyoming pays royalties to the State of Wyoming, 
the U.S. Bureau of Land Management and Rock Springs Royalty Company, 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 ton of such products. These royalty payments are typically subject to a minimum domestic production volume 
from the Green River Basin facility, although Ciner Wyoming is obligated to pay minimum royalties or annual rentals to its lessors 
and licensor regardless of actual sales. The royalty rates paid to Ciner Wyoming’s lessors and licensor may change upon renewal 
of such leases and license. Under the license with Rock Springs, the applicable royalty rate may vary based on a most favored 
nation clause in the license which is currently the subject of litigation in Wyoming.

As a minority interest owner in Ciner Wyoming, we do not operate and are not involved in the day-to-day operation of the 
trona ore mine or soda ash production plant. Our partner, Ciner Resources LP manages the mining and plant operations. We appoint 
three of the seven members of the Board of Managers of Ciner Wyoming and have certain limited negative controls relating to the 
company.

Construction Aggregates Segment 

Our Construction Aggregates segment consists of our construction materials business that was acquired on October 1, 2014. 
The business operates four limestone quarries, one underground limestone mine, five sand and gravel plants, two asphalt plants 
and  two  marine  terminals. As  of  December 31,  2017, Construction Aggregates  controlled  approximately  400  million  tons  of 
estimated aggregates reserves, including approximately 108 million tons of reserves leased at the Grand Rivers operation from 
the Coal Royalty and Other segment. The reserve estimates for each of Construction Aggregates’ properties were prepared internally 
and  audited  by  an  independent  third  party  advisor.  During  the  year  ended  December 31,  2017,  Construction Aggregates  sold 
approximately 6.3 million tons of crushed stone and gravel, including brokered stone, 1.3 million tons of sand and 0.3 million tons 
of asphalt. Our Construction Aggregates business is seasonal, with production typically lower in the first quarter of each year due 
to winter weather.

Construction Aggregates’  four  operating  businesses  are  Laurel Aggregates,  located  in  Lake  Lynn,  Pennsylvania,  Winn 
Materials/McIntosh Construction, located in Clarksville, Tennessee, Grand Rivers, located in Grand Rivers, Kentucky and Southern 
Aggregates, located near Baton Rouge, Louisiana. The following map shows the locations of each of Construction Aggregates’ 
operations:

Laurel Aggregates

Laurel Aggregates ("Laurel") is a limestone mining company located in Lake Lynn, Pennsylvania. Its operations consist of 
a surface and underground mines and use conventional drilling, blasting and crushing methods. The surface mine is located on 
approximately  100  acres  of  owned  property,  and  the  underground  reserves  are  located  on  approximately  670  acres  of  leased 
property. Laurel Aggregates pays royalties for material mined and sold from its leased property. Laurel also brokers stone for third 
party quarries located in Ohio and Pennsylvania. Crushed stone is loaded into third party trucks for delivery to customers located 
in  southwestern  Pennsylvania,  northeastern  West  Virginia  and  eastern  Ohio.  Laurel’s  customers  consist  of  oilfield  service 
companies, natural gas exploration and production companies and construction and contracting companies.

Winn Materials/McIntosh Construction

Winn Materials’ ("Winn") operations consist of two crushed stone quarries and a river terminal, while McIntosh Construction 
("McIntosh") is a complementary asphalt producer and paving company. Together, the two companies function as a vertically 
integrated unit. The operations of Winn/McIntosh are located in Clarksville, Tennessee, which is located approximately 45 miles 
northwest of Nashville.

Winn mines and produces hard rock limestone using conventional drilling, blasting and crushing methods. Winn primarily 
leases its properties at its two quarries located in Clarksville and in Trenton, Kentucky and pays royalties for material produced 
and sold from the leased properties. Winn’s marine terminal business is located on the Cumberland River, adjacent to Winn’s 
Clarksville quarry. Its dock transloads various materials by barge. Through the river terminal, Winn loads out crushed stone and 
also imports products such as river and granite sand, fertilizer, and agricultural products for the local and regional markets. The 
river terminal is currently being expanded to meet growing demand for additional imported product into these markets. Crushed 
stone produced at Winn’s quarries and products imported from the river terminal are loaded onto third party trucks for delivery to 
Winn’s customers.

17

McIntosh sells asphalt to third parties and also operates its own paving business. Winn supplies most of McIntosh’s crushed 
stone and sand used for both its asphalt production and construction needs. The Winn/McIntosh businesses sell to and provide 
services for residential, commercial and industrial customers. These businesses also supply and provide construction services for 
infrastructure and highway construction projects primarily within Montgomery County, Tennessee, including for Fort Campbell, 
one of the largest Army bases in the United States.

Southern Aggregates

Southern Aggregates ("Southern") is a sand and gravel mining company based in Denham Springs, Louisiana, approximately 
25 miles northeast of Baton Rouge, Louisiana. Southern operates six sand and gravel operations. Suction dredges extract sand and 
gravel, and the mined material is processed at plants generally located at each site. The plants separate gravel and saleable sand 
from waste sand and clays, with the waste returned to mined-out sections of pits. The saleable sand and gravel material is loaded 
onto third party trucks for delivery to Southern’s customers. Southern leases its mineral reserves and pays royalties for material 
produced and sold from the leased properties. Southern’s markets extend approximately 100 miles west and south from its operating 
locations, including to the cities of Baton Rouge, Lafayette and New Orleans. Southern’s customers consist primarily of ready 
mix concrete companies, asphalt producers and contractors.

Grand Rivers

The Construction Aggregates segment purchased a 514 acre hard rock quarry operation located on the Tennessee River near 
Grand Rivers, Kentucky from one of NRP’s aggregates lessees that had previously idled the operation. This operation continues 
to lease reserves from NRP and sell its limestone aggregates in both the local market, loaded onto third party trucks, and to river-
based markets through a barge load out terminal. 

The Grand Rivers quarry produces various grades of crushed limestone products mined through its open pit using conventional 
drilling, blasting and crushing methods performed by a third party mining contractor. Grand Rivers pays royalties for material 
produced and sold from the leased property to a subsidiary of NRP. Crushed stone is loaded into third party trucks for delivery to 
customers in Kentucky and barges for delivery to customers along the Mississippi River Basin and related waterways. Grand 
Rivers customers currently consist primarily of ready mix concrete companies and construction and contracting companies.

Significant Customers 

We have a significant concentration of revenues with Foresight Energy and its subsidiaries, with total revenues of $70.5 
million in 2017 from three different mining operations. For additional information on significant customers, refer to Note 16. 
Major Customers in the Notes to Consolidated Financial Statements under "Item 8. Financial Statements and Supplementary Data." 

We have a lawsuit pending against Foresight Energy and certain of its subsidiaries, including Hillsboro Energy, relating to 
the wrongful declaration of force majeure at the Deer Run mine. We also have a lawsuit pending against Macoupin Energy for 
breach of contract for wrongful recoupment of previously paid minimum royalties. For additional information on these lawsuits, 
see  Note  17.  Commitments  and  Contingencies  in  the  Notes  to  Consolidated  Financial  Statements  under  "Item  8.  Financial 
Statements and Supplementary Data" and "Item 3. Legal Proceedings" included elsewhere in this Annual Report on Form 10-K.

Competition 

We face competition from land companies, coal producers, international steel companies and private equity firms in purchasing 
coal reserves and royalty producing properties. Numerous producers in the coal industry make coal marketing intensely competitive. 
Our lessees compete among themselves and with coal producers in various regions of the United States for domestic sales. Lessees 
compete with both large and small producers nationwide on the basis of coal price at the mine, coal quality, transportation cost 
from the mine to the customer and the reliability of supply. Continued demand for our coal and the prices that our lessees obtain 
are also affected by demand for electricity and steel, as well as government regulations, technological developments and the 
availability and the cost of generating power from alternative fuel sources, including nuclear, natural gas and hydroelectric power.

Ciner Wyoming's trona mining and soda ash refinery business faces competition from a number of soda ash producers in the 
United States, Europe and Asia, some of which have greater market share and greater financial, production and other resources 
than Ciner Wyoming does. Some of Ciner Wyoming’s competitors are diversified global corporations that have many lines of 

18

 
business and some have greater capital resources and may be in a better position to withstand a long-term deterioration in the soda 
ash market. Other competitors, even if smaller in size, may have greater experience and stronger relationships in their local markets. 
Competitive pressures could make it more difficult for Ciner Wyoming to retain its existing customers and attract new customers, 
and could also intensify the negative impact of factors that decrease demand for soda ash in the markets it serves, such as adverse 
economic conditions, weather, higher fuel costs and taxes or other governmental or regulatory actions that directly or indirectly 
increase the cost or limit the use of soda ash.

The construction aggregates industry is highly competitive and fragmented with a large number of independent local producers 
operating in the local markets we serve. Additionally, our construction aggregates business also competes against large private 
and public companies, some of which are significantly vertically integrated. This significant competition could lead to lower prices 
and lower sales volumes in some markets, negatively affecting our earnings and cash flows.

Title to Property 

We own a significant percentage of our coal and aggregates reserves in fee as of December 31, 2017. We lease the remainder 
from unaffiliated third parties, including leasing aggregates reserves for Construction Aggregates' construction materials business. 
Ciner Wyoming also leases or licenses its trona reserves. We believe that we have satisfactory title to all of our mineral properties, 
but we have not had a qualified title company confirm this belief. Although title to these properties is subject to encumbrances in 
certain cases, such as customary easements, rights-of-way, interests generally retained in connection with the acquisition of real 
property, licenses, prior reservations, leases, liens, restrictions and other encumbrances, we believe that none of these burdens will 
materially detract from the value of our properties or from our interest in them or will materially interfere with their use in the 
operation of our business.

For most of our properties, the surface, oil and gas and mineral or coal estates are not owned by the same entities. Some of 
those entities are our affiliates. State law and regulations in most of the states where we do business require the oil and gas owner 
to coordinate the location of wells so as to minimize the impact on the intervening coal seams. We do not anticipate that the 
existence of the severed estates will materially impede development of the minerals on our properties.

Regulation and Environmental Matters 

General

Operations on our properties must be conducted in compliance with all applicable federal, state and local laws and regulations. 
These laws and regulations include matters involving the discharge of materials into the environment, employee health and safety, 
mine  permits  and  other  licensing  requirements,  reclamation  and  restoration  of  mining  properties  after  mining  is  completed, 
management  of  materials  generated  by  mining  operations,  surface  subsidence  from  underground  mining,  water  pollution, 
legislatively mandated benefits for current and retired coal miners, air quality standards, protection of wetlands, plant and wildlife 
protection, limitations on land use, storage of petroleum products and substances which are regarded as hazardous under applicable 
laws and management of electrical equipment containing polychlorinated biphenyls (PCBs). Because of extensive, comprehensive 
and  often  ambiguous  regulatory  requirements,  violations  during  natural  resource  extraction  operations  are  not  unusual  and, 
notwithstanding compliance efforts, we do not believe violations can be eliminated entirely.

While it is not possible to quantify the costs of compliance with all applicable federal, state and local laws and regulations, 
those costs have been and are expected to continue to be significant. Our lessees in our coal and aggregates royalty businesses are 
required to post performance bonds pursuant to federal and state mining laws and regulations for the estimated costs of reclamation 
and mine closures, including the cost of treating mine water discharge when necessary. In many states our lessees also pay taxes 
into  reclamation  funds  that  states  use  to  achieve  reclamation  where  site  specific  performance  bonds  are  inadequate  to  do  so. 
Determinations by federal or state agencies that site specific bonds or state reclamation funds are inadequate could result in increased 
bonding costs for our lessees or even a cessation of operations if adequate levels of bonding cannot be maintained. We do not 
accrue for reclamation costs because our lessees are both contractually liable and liable under the permits they hold for all costs 
relating to their mining operations, including the costs of reclamation and mine closures. Although the lessees typically accrue 
adequate amounts for these costs, their future operating results would be adversely affected if they later determined these accruals 
to be insufficient. In recent years, compliance with these laws and regulations has substantially increased the cost of coal mining 
for all domestic coal producers.

19

In addition, the electric utility industry, which is the most significant end-user of thermal coal, is subject to extensive regulation 
regarding the environmental impact of its power generation activities, which has affected and is expected to continue to affect 
demand for coal mined from our properties. Current and future proposed legislation and regulations could be adopted that will 
have a significant additional impact on the mining operations of our lessees or their customers’ ability to use coal and may require 
our lessees or their customers to change operations significantly or incur additional substantial costs that would negatively impact 
the coal industry.

Many of the statutes discussed below also apply to our Construction Aggregates mining and production operations and Ciner 
Wyoming’s trona mining and soda ash production operations, and therefore we do not present a separate discussion of statutes 
related to those activities, except where appropriate.

Air Emissions

The Clean Air Act and corresponding state and local laws and regulations affect all aspects of our business. The Clean Air 
Act directly impacts our lessees’ coal mining and processing operations by imposing permitting requirements and, in some cases, 
requirements to install certain emissions control equipment, on sources that emit various hazardous and non-hazardous air pollutants. 
The Clean Air Act also indirectly affects coal mining operations by extensively regulating the air emissions of coal-fired electric 
power generating plants. There have been a series of federal rulemakings that are focused on emissions from coal-fired electric 
generating facilities, including the Cross-State Air Pollution Rule (CSAPR), regulating emissions of nitrogen oxide and sulfur 
dioxide, and the Mercury and Air Toxics Rule (MATS), regulating emissions of hazardous air pollutants. Installation of additional 
emissions control technologies and other measures required under these and other U.S. Environmental Protection Agency (EPA) 
regulations, including EPA’s proposed rules to regulate greenhouse gas (GHG) emissions from new and existing fossil fuel-fired 
power plants, will make it more costly to operate coal-fired power plants and could make coal a less attractive or even effectively 
prohibited fuel source in the planning, building and operation of power plants in the future. These rules and regulations have 
resulted in a reduction in coal’s share of power generating capacity, which has negatively impacted our lessees’ ability to sell coal 
and our coal-related revenues. Further reductions in coal’s share of power generating capacity as a result of compliance with 
existing or proposed rules and regulations would have a material adverse effect on our coal-related revenues.

Carbon Dioxide and Greenhouse Gas Emissions

In December 2009, EPA determined that emissions of carbon dioxide, methane, and other GHGs present an endangerment 
to  public  health  and  welfare  because  emissions  of  such  gases  are,  according  to  EPA,  contributing  to  warming  of  the  Earth’s 
atmosphere  and  other  climatic  changes.  Based  on  its  findings,  EPA  began  adopting  and  implementing  regulations  to  restrict 
emissions of GHGs under various provisions of the Clean Air Act.

In August 2015, EPA published its final Clean Power Plan Rule, a multi-factor plan designed to cut carbon pollution from 
existing power plants, including coal-fired power plants. The rule requires improving the heat rate of existing coal-fired power 
plants and substituting lower carbon-emission sources like natural gas and renewables in place of coal. As promulgated, the rule 
would force many existing coal-fired power plants to incur substantial costs in order to comply or alternatively result in the closure 
of some of these plants, likely resulting in a material adverse effect on the demand for coal by electric power generators. The rule 
is being challenged by several states, industry participants and other parties in the United States Court of Appeals for the District 
of Columbia Circuit.  In February 2016, the Supreme Court of the United States stayed the Clean Power Plan Rule pending a 
decision by the District of Columbia Circuit as well as any subsequent review by the Supreme Court. In April 2017, the United 
States Court of Appeals for the District of Columbia Circuit granted EPA’s motion to hold the litigation in abeyance. In December 
2017, EPA issued a proposed rule repealing the Clean Power Plan Rule and issued an Advance Notice of Proposed Rulemaking 
soliciting information regarding a potential replacement rule to the Clean Power Plan Rule.    

In October 2015, EPA published its final rule on performance standards for greenhouse gas emissions from new, modified, 
and reconstructed electric generating units. The final rule requires new steam generating units to use highly efficient supercritical 
pulverized coal boilers that use partial post-combustion carbon capture and storage technology. The final emission standard is less 
stringent than EPA had originally proposed due to updated cost assumptions, but could still have a material adverse effect on new 
coal-fired power plants. The final rule has been challenged by several states, industry participants and other parties in the United 
States Court of Appeals for the District of Columbia Circuit, but is not subject to a stay. In April 2017, the court granted EPA’s 
motion to hold the litigation in abeyance while EPA reviews the rule.

20

President Obama also announced an emission reduction agreement with China’s President Xi Jinping in November 2014. 
The United States pledged that by 2025 it would cut climate pollution by 26 to 28% from 2005 levels. China pledged it would 
reach its peak carbon dioxide emissions around 2030 or earlier, and increase its non-fossil fuel share of energy to around 20% by 
2030. In December 2015, the United States was one of 196 countries that participated in the Paris Climate Conference, at which 
the participants agreed to limit their emissions in order to limit global warming to 2°C above pre-industrial levels, with an aspirational 
goal of 1.5°C. While there is no way to estimate the impact of these climate pledges and agreements, they could ultimately have 
an adverse effect on the demand for coal, both nationally and internationally, if implemented. President Trump has expressed a 
desire for the United States to withdraw from the Paris Climate Agreement or to re-negotiate its terms.

EPA has also adopted rules requiring the reporting of GHG emissions from specified large GHG emission sources in the 

United States, including coal-fired electric power plants, on an annual basis.

Hazardous Materials and Waste

The Federal Comprehensive Environmental Response, Compensation and Liability Act (CERCLA or the Superfund law) 
and analogous state laws impose liability, without regard to fault or the legality of the original conduct, on certain classes of persons 
that are considered to have contributed to the release of a “hazardous substance” into the environment. We could become liable 
under federal and state Superfund and waste management statutes if our lessees are unable to pay environmental cleanup costs 
relating  to  hazardous  substances.  In  addition,  we  may  have  liability for  environmental  clean-up  costs  in  connection  with  our 
Construction Aggregates and Ciner Wyoming soda ash businesses.

Water Discharges

Operations conducted on our properties can result in discharges of pollutants into waters. The Clean Water Act and analogous 
state laws and regulations create two permitting programs for mining operations. The National Pollutant Discharge Elimination 
System (NPDES) program under Section 402 of the statute is administered by the states or EPA and regulates the concentrations 
of pollutants in discharges of waste and storm water from a mine site. The Section 404 program is administered by the Army Corps 
of Engineers and regulates the placement of overburden and fill material into channels, streams and wetlands that comprise “waters 
of the United States.” The scope of waters that may fall within the jurisdictional reach of the Clean Water Act is expansive and 
may include land features not commonly understood to be a stream or wetlands. In June 2015, EPA issued a new rule defining the 
scope of “Waters of the United States” (WOTUS) that are subject to regulation. The WOTUS rule was challenged by a number 
of states and private parties in federal district and circuit courts, and the rule was stayed on a nationwide basis by the Sixth Circuit 
Court of Appeals in October 2015. In January 2018, the United States Supreme Court ruled that challenges to the WOTUS rule 
are properly within the jurisdiction of the federal district courts rather than the Sixth Circuit or other federal appellate courts. In 
light of the Supreme Court's ruling, the nationwide stay will likely be lifted, which could result in further district court litigation 
regarding stays of the rule in districts where challenges to the rule have been filed. A challenge to the Sixth Circuit’s determination 
that it has exclusive jurisdiction over the matter is currently before the Supreme Court of the United States. In December 2017, 
EPA and the Corps proposed a rule to repeal the WOTUS rule and are scheduled to propose a replacement to the WOTUS rule in 
May 2018. The Clean Water Act and its regulations prohibit the unpermitted discharge of pollutants into such waters, including 
those from a spill or leak. Similarly, Section 404 also prohibits discharges of fill material and certain other activities in waters 
unless authorized by the issued permit.

In connection with its review of permits, EPA has at times sought to reduce the size of fills and to impose limits on specific 
conductance (conductivity) and sulfate at levels that can be unachievable absent treatment at many mines. Such actions by EPA 
could make it more difficult or expensive to obtain or comply with such permits, which could, in turn, have an adverse effect on 
our coal-related revenues.

In addition to government action, private citizens’ groups have continued to be active in bringing lawsuits against operators 
and landowners. Since 2012, several citizen group lawsuits have been filed against mine operators for allegedly violating conditions 
in their National Pollutant Discharge Elimination System (“NPDES”) permits requiring compliance with West Virginia’s water 
quality  standards.  Some  of  the  lawsuits  allege  violations  of  water  quality  standards  for  selenium,  whereas  others  allege  that 
discharges of conductivity and sulfate are causing violations of West Virginia’s narrative water quality standards, which generally 
prohibit adverse effects to aquatic life. The citizen suit groups have sought penalties as well as injunctive relief that would limit 
future discharges of selenium, conductivity or sulfate. The federal district court for the Southern District of West Virginia has ruled 
in favor of the citizen suit groups in multiple suits alleging violations of the water quality standard for selenium and in two suits 
alleging violations of water quality standards due to discharges of conductivity (one of which was upheld on appeal by the United 

21

States Court of Appeals for the Fourth Circuit in January 2017). Additional rulings requiring operators to reduce their discharges 
of selenium, conductivity or sulfate could result in large treatment expenses for our lessees.

Since 2013, several citizen group lawsuits have been filed against landowners alleging ongoing discharges of pollutants, 
including selenium and conductivity, from valley fills located at reclaimed mountaintop removal mining sites in West Virginia. In 
each case, the mine on the subject property has been closed, the property has been reclaimed, and the state reclamation bond has 
been released. Any determination that a landowner or lessee has liability for discharges from a previously reclaimed mine site 
could result in substantial compliance costs or fines and would result in uncertainty as to continuing liability for completed and 
reclaimed coal mine operations.

Other Regulations Affecting the Mining Industry

Mine Health and Safety Laws

The operations of our coal lessees, our Construction Aggregates business, and Ciner Wyoming are subject to stringent health 
and safety standards that have been imposed by federal legislation since the adoption of the Mine Health and Safety Act of 1969. 
The Mine Health and Safety Act of 1969 resulted in increased operating costs and reduced productivity. The Mine Safety and 
Health Act of 1977, which significantly expanded the enforcement of health and safety standards of the Mine Health and Safety 
Act of 1969, imposes comprehensive health and safety standards on all mining operations. In addition, the Black Lung Acts require 
payments of benefits by all businesses conducting current mining operations to coal miners with black lung or pneumoconiosis 
and to some beneficiaries of miners who have died from this disease.

Mining accidents in recent years have received national attention and instigated responses at the state and national level that 
have resulted in increased scrutiny of current safety practices and procedures at all mining operations, particularly underground 
mining operations. Since 2006, heightened scrutiny has been applied to the safe operations of both underground and surface mines. 
This increased level of review has resulted in an increase in the civil penalties that mine operators have been assessed for non-
compliance. Operating companies and their supervisory employees have also been subject to criminal convictions. The Mine Safety 
and Health Administration (MSHA) has also advised mine operators that it will be more aggressive in placing mines in the Pattern 
of Violations program, if a mine’s rate of injuries or significant and substantial citations exceed a certain threshold. A mine that is 
placed in a Pattern of Violations program will receive additional scrutiny from MSHA.

Surface Mining Control and Reclamation Act of 1977

The Surface Mining Control and Reclamation Act of 1977 (SMCRA) and similar statutes enacted and enforced by the states 
impose on mine operators the responsibility of reclaiming the land and compensating the landowner for types of damages occurring 
as a result of mining operations. To ensure compliance with any reclamation obligations, mine operators are required to post 
performance bonds. Our coal lessees are contractually obligated under the terms of our leases to comply with all federal, state and 
local laws, including SMCRA. Upon completion of the mining, reclamation generally is completed by seeding with grasses or 
planting trees for use as pasture or timberland, as specified in the reclamation plan approved by the state regulatory authority. In 
addition, higher and better uses of the reclaimed property are encouraged.

Mining Permits and Approvals

Numerous governmental permits or approvals such as those required by SMCRA and the Clean Water Act are required for 
mining operations. In connection with obtaining these permits and approvals, our lessees may be required to prepare and present 
to federal, state or local authorities data pertaining to the effect or impact that any proposed production of coal may have upon the 
environment.  The  requirements  imposed  by  any  of  these  authorities  may  be  costly  and  time  consuming  and  may  delay 
commencement or continuation of mining operations.

In order to obtain mining permits and approvals from state regulatory authorities, mine operators, including our lessees, must 
submit a reclamation plan for reclaiming the mined property upon the completion of mining operations. Our lessees have obtained 
or applied for permits to mine a majority of the reserves that are currently planned to be mined over the next five years. Our lessees 
are also in the planning phase for obtaining permits for the additional reserves planned to be mined over the following five years. 
However, given the imposition of new requirements in the permits in the form of policies and the increased oversight review that 
has been exercised by EPA, there are no assurances that they will not experience difficulty and delays in obtaining mining permits 

22

in the future. In addition, EPA has used its authority to create significant delays in the issuance of new permits and the modification 
of existing permits, which has led to substantial delays and increased costs for coal operators.

Regulations under SMCRA include a “stream buffer zone” rule that prohibits certain mining activities near streams. In 2008, 
the federal Office of Surface Mining (OSM), which implements SMCRA, revised the stream buffer zone rule, making it more 
clear that valley fills are not prohibited by the rule. Environmental groups challenged the revision to the buffer zone rule in federal 
court. In February 2014, the federal court vacated the 2008 rule and in December 2014, OSM reinstated the previous version of 
the rule, without clarifying whether the previous version of the rule impacts the ability to construct excess fills. In December 2016, 
OSM finalized the “Stream Protection Rule,” a re-written version of the stream buffer zone rule which requires coal operators to 
restrict mining within 100 feet of waterways. The rule also requires states to impose additional information gathering and monitoring 
at and around coal mining sites and mandates new financial assurance and reclamation requirements. The rule was repealed by 
Congress in February 2017; however, to the extent the rule is ever reinstated, it could restrict our lessees’ ability to develop new 
mines, or could require our lessees to modify existing operations, which could have an adverse effect on our coal-related revenues.

Employees and Labor Relations 

As of December 31, 2017, affiliates of our general partner employed 64 people who directly supported our operations. None 
of these employees were subject to a collective bargaining agreement. We employed 243 people who supported the construction 
aggregates mining and production operations. None of these employees were subject to a collective bargaining agreement.

ITEM 1A.  

RISK FACTORS 

Risks Related to Our Business 

To the extent our board of directors deems appropriate, it may determine to decrease the amount of our quarterly distribution 
or suspend or eliminate the distribution altogether. In addition, our debt agreements and our partnership agreement place 
restrictions on our ability to pay the quarterly distribution under certain circumstances.

Because distributions on the common units are dependent on the amount of cash we generate, distributions fluctuate based 
on our performance. The actual amount of cash that is available to be distributed each quarter depends on numerous factors, some 
of which are beyond our control and the control of the general partner. Cash distributions are dependent primarily on cash flow, 
and not solely on profitability, which is affected by non-cash items. Therefore, cash distributions might be made during periods 
when we record losses and might not be made during periods when we record profits. The actual amount of cash we have to 
distribute each quarter is reduced by payments in respect of debt service and other contractual obligations, including distributions 
on the preferred units, fixed charges, maintenance capital expenditures and reserves for future operating or capital needs that the 
board of directors may determine are appropriate. We still have significant debt service obligations and obligations to pay cash 
distributions on our preferred units. To the extent our board of directors deems appropriate, it may determine to decrease the amount 
of the quarterly distribution on our common units or suspend or eliminate the distribution on our common units altogether. In 
addition, because our unitholders are required to pay income taxes on their respective shares of our taxable income, our unitholders 
may be required to pay taxes in excess of any future distributions we make. Our unitholders' share of our portfolio income may 
be taxable to them even though they receive other losses from our activities. See "—Tax Risks to Our Unitholders—Our unitholders 
are required to pay taxes on their share of our income even if they do not receive any cash distributions from us. Our unitholders' 
share of our portfolio income may be taxable to them even though they receive other losses from our activities." 

The agreements governing our indebtedness and preferred units restrict our ability to raise, and in some cases continue to 
pay, distributions on our common units. Opco’s revolving credit agreement, the indenture governing our 2022 Notes and our 
partnership agreement each require that we meet certain consolidated leverage tests in order to raise our quarterly distribution on 
the common units above the current level of $0.45 per quarter. The maximum leverage covenant under Opco’s revolving credit 
facility will step down permanently from 4.0x to 3.0x if we increase the common unit distribution above the current level. In 
addition, under our partnership agreement, to the extent we have paid any distributions on the preferred units in kind ("PIK units"), 
and such PIK units are still outstanding at any time after January 1, 2022, we will be prohibited from making any distributions 
with respect to our common units until we have redeemed all such PIK units in cash. For more information on restrictions on our 
ability to make distributions on our common units, see "Management’s Discussion and Analysis of Financial Condition and Results 
of Operations—Liquidity and Capital Resources" and "Item 8. Financial Statements and Supplementary Data—Note 13. Debt."

Our leverage and debt service obligations may adversely affect our financial condition, results of operations and business 
prospects.  

As of December 31, 2017, we and our subsidiaries had approximately $827.8 million of total indebtedness. The terms and 

conditions governing the indenture for NRP’s 2022 Notes and Opco’s revolving credit facility and senior notes:

• 

• 

• 

• 

• 

require us to meet certain leverage and interest coverage ratios;

require us to dedicate a substantial portion of our cash flow from operations to service our existing debt, thereby reducing 
the cash available to finance our operations and other business activities and could limit our flexibility in planning for 
or reacting to changes in our business and the industries in which we operate;

increase our vulnerability to economic downturns and adverse developments in our business;

limit our ability to access the bank and capital markets to raise capital on favorable terms or to obtain additional financing 
for working capital, capital expenditures or acquisitions or to refinance existing indebtedness;

place restrictions on our ability to obtain additional financing, make investments, lease equipment, sell assets and engage 
in business combinations;

24

 
• 

place us at a competitive disadvantage relative to competitors with lower levels of indebtedness in relation to their overall 
size or less restrictive terms governing their indebtedness;

•  make it more difficult for us to satisfy our obligations under our debt agreements and increase the risk that we may 

default on our debt obligations; and

• 

limit management’s discretion in operating our business.

Our ability to meet our expenses and debt obligations will depend on our future performance, which will be affected by 
financial, business, economic, regulatory and other factors. We will not be able to control many of these factors, such as economic 
conditions and governmental regulation. We cannot be certain that our cash flow will be sufficient to allow us to pay the principal 
and interest on our debt and meet our other obligations, including payment of distributions on the preferred units. If we do not 
have sufficient funds, we may be required to refinance all or part of our existing debt, borrow more money, or sell assets or raise 
equity at unattractive prices. We are required to make substantial principal repayments each year in connection with Opco’s senior 
notes, with approximately $81 million due thereunder during 2018. To the extent we borrow to make some of these payments, we 
may not be able to refinance these amounts on terms acceptable to us, if at all. We may not be able to refinance our debt, sell assets, 
borrow more money or access the bank and capital markets on terms acceptable to us, if at all. Our ability to comply with the 
financial and other restrictive covenants in our debt agreements will be affected by the levels of cash flow from our operations 
and future events and circumstances beyond our control. Failure to comply with these covenants would result in an event of default 
under our indebtedness, and such an event of default could adversely affect our business, financial condition and results of operations.

Ongoing disputes with Foresight Energy could have an adverse effect on our financial condition and results of operations. In 
addition, if the Deer Run mine remains idled for an extended period or does not resume operations, our financial condition 
and results of operations could be adversely affected.

Foresight Energy is our largest lessee, and in 2017, we derived approximately 19% of our revenues from them. We are 
currently in disputes with them with respect to two of their four mining operations in which we have an interest. Foresight Energy’s 
Deer Run mine (which we also refer to as our Hillsboro property) has been idled for almost three years. Foresight Energy has 
declared a force majeure event at the Deer Run mine and failed to make $76.0 million in required minimum deficiency payments 
to us as of the date hereof. Such amount is expected to increase by $7.5 million for each quarter with respect to which Foresight 
Energy fails to make the required minimum payment. We have a lawsuit pending against Foresight Energy and Hillsboro Energy 
to recover the amounts owed to us and compel them to make the required minimum deficiency payments under the lease. We do 
not currently have an estimate as to when the mine will resume coal production. If the mine remains idled for an extended period, 
if the mine is permanently closed or if Hillsboro continues to fail to pay its required contractual minimums, our financial condition 
could be adversely affected. 

In addition, we have also filed a lawsuit against Foresight Energy’s Macoupin subsidiary, which has failed to comply with 
the terms of the coal mining, rail loadout and rail loop leases at the Macoupin mine by incorrectly recouping previously paid 
minimum royalties. The amount owed to us by Macoupin through December 31, 2017 is approximately $9.5 million. See "Item 
3. Legal Proceedings" included elsewhere in this Annual Report on Form 10-K for more information on our lawsuits against 
Foresight Energy. These ongoing disputes and further deterioration of our relationship with our largest lessee could have a material 
adverse effect on our financial condition and results of operations.  

Prices for both metallurgical and thermal coal are volatile and depend on a number of factors beyond our control.  Declines 
in prices could have a material adverse effect on our business and results of operations.

Coal prices remain at relatively low levels and continue to be volatile. Although metallurgical coal prices have improved 
since 2016 lows, the current pricing environment may not be sustained, and prices could decline substantially. Thermal coal prices 
remain relatively steady, but production by some of our lessees may not be economic if the prices decline further or remain at 
current levels. The prices our lessees receive for their coal depend upon factors beyond their or our control, including:

• 

• 

• 

• 

the supply of and demand for domestic and foreign coal;

domestic and foreign governmental regulations and taxes;

changes in fuel consumption patterns of electric power generators;

the price and availability of alternative fuels, especially natural gas;

25

• 

global economic conditions, including the strength of the U.S. dollar relative to other currencies and the demand for 
steel;

• 

the proximity to and capacity of transportation facilities;

•  weather conditions; and

• 

the effect of worldwide energy conservation measures.

Natural gas is the primary fuel that competes with thermal coal for power generation. Relatively low natural gas prices have 
resulted in a number of utilities switching from thermal coal to natural gas to the extent that it is practical to do so. This switching 
has resulted in a decline in thermal coal prices, and to the extent that natural gas prices remain low, thermal coal prices will also 
remain low. The closure of coal-fired power plants as a result of increased governmental regulations or the inability to comply 
with such regulations has also resulted in a decrease in the demand for thermal coal.

Our lessees produce a significant amount of the metallurgical coal that is used in both the U.S. and foreign steel industries. 
Since the amount of steel that is produced is tied to global economic conditions, declines in those conditions could result in the 
decline of steel, coke and metallurgical coal production. Since metallurgical coal is priced higher than thermal coal, some mines 
on our properties may only operate profitably if all or a portion of their production is sold as metallurgical coal. If these mines are 
unable to sell metallurgical coal, they may not be economically viable and may be temporarily idled or closed. Any potential future 
lessee bankruptcy filings could create additional uncertainty as to the future of operations on our properties and could have a 
material adverse effect on our business and results of operations.

To the extent our lessees are unable to economically produce coal over the long term, the carrying value of our reserves could 
be  adversely  affected. A  long  term  asset  generally  is  deemed  impaired  when  the  future  expected  cash  flow  from  its  use  and 
disposition is less than its book value. Future impairment analyses could result in additional downward adjustments to the carrying 
value of our assets.

Mining operations are subject to operating risks that could result in lower revenues to us.

Our revenues are largely dependent on the level of production of minerals from our properties, and any interruptions to the 
production from our properties would reduce our revenues. The level of production is subject to operating conditions or events 
beyond our or our lessees’ control including:

• 

• 

the inability to acquire necessary permits or mining or surface rights;

changes or variations in geologic conditions, such as the thickness of the mineral deposits and, in the case of coal, the 
amount of rock embedded in or overlying the coal deposit;

•  mining and processing equipment failures and unexpected maintenance problems;

• 

• 

• 

• 

• 

the availability of equipment or parts and increased costs related thereto;

the availability of transportation facilities and interruptions due to transportation delays;

adverse weather and natural disasters, such as heavy rains and flooding;

labor-related interruptions; and

unexpected mine safety accidents, including fires and explosions.

Under the current regulatory environment, there is substantial uncertainty relating to the ability of our coal lessees to be 
issued permits necessary to conduct mining operations. The non-issuance of permits has limited the ability of our coal lessees to 
open new operations, expand existing operations, and may preclude new acquisitions in which we might otherwise be involved. 
We and our lessees may also incur costs and liabilities resulting from claims for damages to property or injury to persons arising 
from our or their operations. If we or our lessees are pursued for these sanctions, costs and liabilities, mining operations and, as a 
result, our revenues could be adversely affected.

The Construction Aggregates segment currently operates four hard rock quarries, one underground limestone mine, six sand 
and gravel plants, two asphalt plants and two marine terminals. As an operator of these assets, we are exposed to risks that we 
have not historically been exposed to in our mineral rights and royalties business. Such risks include, but are not limited to, prices 
and demand for construction aggregates, capital and operating expenses necessary to maintain operations, production levels, general 
26

economic conditions, conditions in the local markets that we serve, inclement or hazardous weather conditions and typically lower 
production levels in the winter months, permitting risk, fire, explosions or other accidents, and unanticipated geologic conditions. 
Any of these risks could result in damage to, or destruction of, our construction aggregates mining properties or production facilities, 
personal injury, environmental damage, delays in mining or processing, reduced revenue or losses or possible legal liability. In 
addition, not all of these risks are reasonably insurable, and our insurance coverage contains limits, deductibles, exclusions and 
endorsements. Our insurance coverage may not be sufficient to meet our needs in the event of loss. Any prolonged downtime or 
shutdowns at our construction aggregates mining properties or production facilities or material loss could have an adverse effect 
on our results of operations.

Changes in fuel consumption patterns by electric power generators resulting in a decrease in the use of coal have resulted in 
and will continue to result in lower coal production by our lessees and reduced coal-related revenues.

The amount of coal consumed for domestic electric power generation is affected primarily by the overall demand for electricity, 
the price and availability of competing fuels for power plants and environmental and other governmental regulations. We expect 
that substantially all newly constructed power plants in the United States will be fired by natural gas because of lower construction 
and compliance costs compared to coal-fired plants and because natural gas is a cleaner burning fuel. The increasingly stringent 
requirements of rules and regulations promulgated under the federal Clean Air Act have resulted in more electric power generators 
shifting from coal to natural-gas-fired power plants, or to other alternative energy sources such as solar and wind. In addition, the 
proposed rules promulgated by the EPA on greenhouse gas emissions from new and existing power plants are expected to further 
limit the construction of new coal-fired generation plants in favor of alternative sources of energy and negatively affect the viability 
of coal-fired power generation. These changes have resulted in reduced coal consumption and the production of coal from our 
properties and are expected to continue to have an adverse effect on our coal-related revenues.

The adoption of climate change legislation or regulations restricting emissions of "greenhouse gases" and other hazardous 
air pollutants have resulted in and will continue to result in reduced demand for our coal, oil and natural gas.

In December 2009, EPA determined that emissions of carbon dioxide, methane, and other GHGs, present an endangerment 
to  public  health  and  welfare  because  emissions  of  such  gases  are,  according  to  EPA,  contributing  to  warming  of  the  Earth’s 
atmosphere and other climatic changes. Based on its findings, EPA has begun adopting and implementing regulations to restrict 
emissions of GHGs under various provisions of the Clean Air Act.

In August 2015, EPA published its final Clean Power Plan Rule, a multi-factor plan designed to cut carbon pollution from 
existing power plants, including coal-fired power plants. The rule requires improving the heat rate of existing coal-fired power 
plants and substituting lower carbon-emission sources like natural gas and renewables in place of coal. The rule will force many 
existing coal-fired power plants to incur substantial costs in order to comply or alternatively result in the closure of some of these 
plants. This rule is being challenged by industry participants and other parties. In February, 2016, the Supreme Court of the United 
States stayed the Clean Power Plan Rule pending a decision by the District of Columbia Circuit as well as any subsequent review 
by the Supreme Court.

In October 2015, EPA published its final rule on performance standards for greenhouse gas emissions from new, modified, 
and reconstructed electric generating units. The final rule requires new steam generating units to use highly efficient supercritical 
pulverized coal boilers that use partial post-combustion carbon capture and storage technology. The final emission standard is less 
stringent than EPA had originally proposed due to updated cost assumptions, but could still have a material adverse effect on new 
coal-fired power plants. The final rule has been challenged by several states, industry participants and other parties in the United 
States Court of Appeals for the District of Columbia Circuit, but is not subject to a stay. Oral arguments are currently scheduled 
for April 2017.

In addition to EPA’s GHG initiatives, there are several other federal rulemakings that are focused on emissions from coal-
fired electric generating facilities, including the Cross-State Air Pollution Rule (CSAPR), regulating emissions of nitrogen oxide 
and sulfur dioxide, and the Mercury and Air Toxics Rule (MATS), regulating emissions of hazardous air pollutants. Installation 
of additional emissions control technologies and other measures required under these and other EPA regulations have made it more 
costly to operate many coal-fired power plants and have resulted in and are expected to continue to result in plant closures. Further 
reductions in coal’s share of power generating capacity as a result of compliance with existing or proposed rules and regulations 
would have a material adverse effect on our coal-related revenues.

27

In addition to climate change and other Clean Air Act legislation, our businesses are subject to numerous other federal, state 
and local laws and regulations that may limit production from our properties and our profitability.

The operations of our lessees, our Construction Aggregates business and Ciner Wyoming are subject to stringent health and 
safety standards under increasingly strict federal, state and local environmental, health and safety laws, including mine safety 
regulations and governmental enforcement policies. The oil and gas industry is also subject to numerous laws and regulations. 
Failure to comply with these laws and regulations may result in the assessment of administrative, civil and criminal penalties, the 
imposition of cleanup and site restoration costs and liens, the issuance of injunctions to limit or cease operations, the suspension 
or revocation of permits and other enforcement measures that could have the effect of limiting production from our properties.

New environmental legislation, new regulations and new interpretations of existing environmental laws, including regulations 
governing  permitting  requirements,  could  further  regulate  or  tax  the  mining  and  oil  and  gas industries  and  may  also  require 
significant changes to operations, the incurrence of increased costs or the requirement to obtain new or different permits, any of 
which could decrease our revenues and have a material adverse effect on our financial condition or results of operations. Under 
SMCRA, our coal lessees have substantial reclamation obligations on properties where mining operations have been completed 
and are required to post performance bonds for their reclamation obligations.  To the extent an operator is unable to satisfy its 
reclamation obligations or the performance bonds posted are not sufficient to cover those obligations, regulatory authorities or 
citizens groups could attempt to shift reclamation liability onto the ultimate landowner, which if successful, could have a material 
adverse effect on our financial condition.

In addition to governmental regulation, private citizens’ groups have continued to be active in bringing lawsuits against coal 
mine operators and land owners that allege violations of water quality standards resulting from ongoing discharges of pollutants 
from reclaimed mining operations, including selenium and conductivity. Any determination that a landowner or lessee has liability 
for discharges from a previously reclaimed mine site would result in uncertainty as to continuing liability for completed and 
reclaimed coal mine operations and could result in substantial compliance costs or fines.

Prices for soda ash are volatile. Any substantial or extended decline in soda ash prices could have an adverse effect on our 
results of operations.

The market price of soda ash directly affects the profitability of Ciner Wyoming’s soda ash production operations. If the 
market price for soda ash declines, Ciner Wyoming’s sales will decrease. Historically, the global market and, to a lesser extent, 
the domestic market for soda ash have been volatile, and those markets are likely to remain volatile in the future. The prices Ciner 
Wyoming receives for its soda ash depend on numerous factors beyond Ciner Wyoming’s control, including worldwide and regional 
economic and political conditions impacting supply and demand. Glass manufacturers and other industrial customers drive most 
of the demand for soda ash, and these customers experience significant fluctuations in demand and production costs. Competition 
from increased use of glass substitutes, such as plastic and recycled glass, has had a negative effect on demand for soda ash. 
Substantial or extended declines in prices for soda ash could have a material adverse effect on our results of operations. In addition, 
Ciner Wyoming relies on natural gas as the main energy source in its soda ash production process. Accordingly, high natural gas 
prices increase Ciner Wyoming’s cost of production and affect its competitive cost position when compared to other foreign and 
domestic soda ash producers.

An adverse outcome in our contingent consideration payment dispute with Anadarko could have an adverse effect on our 
business and liquidity.

In July 2017, Anadarko Holding Company and its subsidiary, Big Island Trona Company (together, “Anadarko”) filed a 
lawsuit against Opco and NRP Trona LLC alleging that a July 2013 simplification of OCI Wyoming’s ownership structure triggered 
an acceleration of an obligation under the purchase agreement with Anadarko to pay additional contingent consideration in full 
and demanded immediate payment of such amount, together with interest, court costs and attorneys’ fees.  While this matter is in 
the very early stages, we would be required to pay up to $40 million, plus interest, court costs and attorneys’ fees if Anadarko 
prevails and is awarded the full damages it seeks. Any such payment could have a material adverse effect on our financial condition. 
For more information, see “Item 3. Legal Proceedings—Anadarko Contingent Consideration Payment Dispute.”

28

The Construction Aggregates segment operates in a highly competitive and fragmented industry, which may negatively impact 
prices, volumes and costs. In addition, both commercial and residential construction are dependent upon the overall U.S. 
economy.

The construction aggregates industry is highly fragmented with a large number of independent local producers operating in 
local markets. Additionally, our construction aggregates business also competes against large private and public companies, some 
of  which  are  significantly  vertically  integrated. Therefore,  there  is  intense  competition  in  a  number  of  markets  in  which  the 
construction aggregates business operates. This significant competition could lead to lower prices and lower sales volumes in some 
markets, negatively affecting our earnings and cash flows.

In addition, commercial and residential construction levels generally move with economic cycles. When the economy is 
strong, construction levels rise and when the economy is weak, construction levels fall. The U.S. economy is recovering from the 
2008-2009 recession, but the pace of recovery is slow. Since construction activity generally lags the recovery after down cycles, 
construction projects have not returned to their pre-recession levels.

If our lessees do not manage their operations well, their production volumes and our royalty revenues could decrease.

We depend on our lessees to effectively manage their operations on our properties. Our lessees make their own business 

decisions with respect to their operations within the constraints of their leases, including decisions relating to:

• 

the payment of minimum royalties;

•  marketing of the minerals mined;

•  mine plans, including the amount to be mined and the method of mining;

• 

• 

• 

• 

• 

• 

• 

• 

• 

processing and blending minerals;

expansion plans and capital expenditures;

credit risk of their customers;

permitting;

insurance and surety bonding;

acquisition of surface rights and other mineral estates;

employee wages;

transportation arrangements;

compliance with applicable laws, including environmental laws; and

•  mine closure and reclamation.

A failure on the part of one of our lessees to make royalty payments, including minimum royalty payments, could give us 
the right to terminate the lease, repossess the property and enforce payment obligations under the lease. If we repossessed any of 
our properties, we would seek a replacement lessee. We might not be able to find a replacement lessee and, if we did, we might 
not be able to enter into a new lease on favorable terms within a reasonable period of time. In addition, the existing lessee could 
be subject to bankruptcy proceedings that could further delay the execution of a new lease or the assignment of the existing lease 
to another operator. If we enter into a new lease, the replacement operator might not achieve the same levels of production or sell 
minerals at the same price as the lessee it replaced. In addition, it may be difficult for us to secure new or replacement lessees for 
small or isolated mineral reserves.

29

We have limited control over the activities on our properties that we do not operate and are exposed to operating risks that we 
do not experience in the royalty business.

We do not have control over the operations of Ciner Wyoming. We have limited approval rights with respect to Ciner Wyoming, 
and our partner controls most business decisions, including decisions with respect to distributions and capital expenditures. Adverse 
developments  in  Ciner  Wyoming’s  business  would  result  in  decreased  distributions  to  NRP.  In  addition,  we  are  ultimately 
responsible for operating the transportation infrastructure at Foresight Energy’s Williamson mine, and have assumed the capital 
and operating risks associated with that business. As a result of these investments, we could experience increased costs as well as 
increased liability exposure associated with operating these facilities.

Fluctuations in transportation costs and the availability or reliability of transportation could reduce the production of coal, 
soda ash, construction aggregates, and other minerals from our properties.

Transportation costs represent a significant portion of the total delivered cost for the customers of our lessees. Increases in 
transportation costs could make coal a less competitive source of energy or could make minerals produced by some or all of our 
lessees less competitive than coal produced from other sources. On the other hand, significant decreases in transportation costs 
could result in increased competition for our lessees from producers in other parts of the country.

Our lessees depend upon railroads, barges, trucks and beltlines to deliver minerals to their customers. Disruption of those 
transportation services due to weather-related problems, mechanical difficulties, strikes, lockouts, bottlenecks and other events 
could temporarily impair the ability of our lessees to supply minerals to their customers. Our lessees’ transportation providers may 
face difficulties in the future that may impair the ability of our lessees to supply minerals to their customers, resulting in decreased 
royalty revenues to us.

In addition, Ciner Wyoming transports its soda ash by rail or truck and ocean vessel. As a result, its business and financial 
results are sensitive to increases in rail freight, trucking and ocean vessel rates. Increases in transportation costs, including increases 
resulting from emission control requirements, port taxes and fluctuations in the price of fuel, could make soda ash a less competitive 
product for glass manufacturers when compared to glass substitutes or recycled glass, or could make Ciner Wyoming’s soda ash 
less competitive than soda ash produced by competitors that have other means of transportation or are located closer to their 
customers. Ciner Wyoming may be unable to pass on its freight and other transportation costs in full because market prices for 
soda ash are generally determined by supply and demand forces. In addition, rail operations are subject to various risks that may 
result in a delay or lack of service at Ciner Wyoming’s facility, and alternative methods of transportation are impracticable or cost-
prohibitive. Any substantial interruption in or increased costs related to the transportation of Ciner Wyoming’s soda ash or the 
failure to renew the rail contract on favorable terms could have a material adverse effect on our financial condition and results of 
operations.

Our reserve estimates depend on many assumptions that may be inaccurate, which could materially adversely affect the quantities 
and value of our reserves.

Coal, aggregates and industrial minerals, reserve engineering requires subjective estimates of underground accumulations 
of  coal,  aggregates  and  industrial  minerals,  and  assumptions  and  are  by  nature  imprecise.  Our  reserve  estimates  may  vary 
substantially from the actual amounts of coal, aggregates and industrial minerals recovered from our reserves. There are numerous 
uncertainties  inherent  in  estimating  quantities  of  reserves,  including  many  factors  beyond  our  control.  Estimates  of  reserves 
necessarily depend upon a number of variables and assumptions, any one of which may, if incorrect, result in an estimate that 
varies considerably from actual results. These factors and assumptions relate to:

• 

• 

• 

• 

• 

future prices, operating costs, capital expenditures, severance and excise taxes, and development and reclamation costs;

production levels;

future technology improvements;

the effects of regulation by governmental agencies; and

geologic and mining conditions, which may not be fully identified by available exploration data.

Actual production, revenue and expenditures with respect to our reserves will likely vary from estimates, and these variations 

may be material. As a result, undue reliance should not be placed on our reserve data that is included in this report.

30

Our lessees could satisfy obligations to their customers with minerals from properties other than ours, depriving us of the ability 
to receive amounts in excess of minimum royalty payments.

Mineral supply contracts generally do not require operators to satisfy their obligations to their customers with resources 
mined from specific reserves. Several factors may influence a lessee’s decision to supply its customers with minerals mined from 
properties we do not own or lease, including the royalty rates under the lessee’s lease with us, mining conditions, mine operating 
costs, cost and availability of transportation, and customer specifications. In addition, lessees move on and off of our properties 
over the course of any given year in accordance with their mine plans. If a lessee satisfies its obligations to its customers with 
minerals from properties we do not own or lease, production on our properties will decrease, and we will receive lower royalty 
revenues.

A lessee may incorrectly report royalty revenues, which might not be identified by our lessee audit process or our mine inspection 
process or, if identified, might be identified in a subsequent period.

We depend on our lessees to correctly report production and royalty revenues on a monthly basis. Our regular lessee audits 
and mine inspections may not discover any irregularities in these reports or, if we do discover errors, we might not identify them 
in the reporting period in which they occurred. Any undiscovered reporting errors could result in a loss of royalty revenues and 
errors identified in subsequent periods could lead to accounting disputes as well as disputes with our lessees.

Risks Related to Our Structure

Unitholders may not be able to remove our general partner even if they wish to do so.

Our general partner manages and operates NRP. Unlike the holders of common stock in a corporation, unitholders have only 
limited voting rights on matters affecting our business. Unitholders have no right to elect the general partner or the directors of 
the general partner on an annual or any other basis.

Furthermore, if unitholders are dissatisfied with the performance of our general partner, they currently have little practical 
ability to remove our general partner or otherwise change its management. Our general partner may not be removed except upon 
the vote of the holders of at least 66 2/3% of our outstanding common units (including common units held by our general partner 
and its affiliates and including common units deemed to be held by the holders of the preferred units who vote along with the 
common unitholders on an as-converted basis). Because of their substantial ownership in us, the removal of our general partner 
would be difficult without the consent of both our general partner and its affiliates and the holders of the preferred units

In addition, the following provisions of our partnership agreement may discourage a person or group from attempting to 

remove our general partner or otherwise change our management:

• 

• 

generally, if a person (other than the holders of preferred units) acquires 20% or more of any class of units then outstanding 
other than from our general partner or its affiliates, the units owned by such person cannot be voted on any matter; and

our partnership agreement contains limitations upon the ability of unitholders to call meetings or to acquire information 
about our operations, as well as other limitations upon the unitholders’ ability to influence the manner or direction of 
management.

As a result of these provisions, the price at which the common units will trade may be lower because of the absence or 

reduction of a takeover premium in the trading price.

The preferred units are senior in right of distributions and liquidation and upon conversion, would result in the issuance of 
additional  common  units  in  the  future,  which  could  result  in  substantial  dilution  of  our  common  unitholders’  ownership 
interests.

The preferred units rank senior to our common units with respect to distribution rights and rights upon liquidation. We are 
required to pay quarterly distributions on the preferred units (plus any PIK Units issued in lieu of preferred units) in an amount 
equal to 12.0% per year prior to paying any distributions on our common units. The preferred units also rank senior to the common 
units in right of liquidation, and will be entitled to receive a liquidation preference in any such case.

31

The preferred units may also be converted into common units under certain circumstances. The number of common units 
issued in any conversion will be based on the then-current trading price of the common units at the time of conversion. Accordingly, 
the lower the trading price of our common units at the time of conversion, the greater the number of common units that will be 
issued upon conversion of the preferred units, which would result in greater dilution to our existing common unitholders. Dilution 
has the following effects on our common unitholders:

• 

• 

• 

an existing unitholder’s proportionate ownership interest in NRP will decrease;

the amount of cash available for distribution on each unit may decrease; and

the relative voting strength of each previously outstanding unit may be diminished; and the market price of the common 
units may decline.

In addition, to the extent the preferred units are converted into more than 66 2/3% of our common units, the holders of the 

preferred will have the right to remove our general partner.

We  may  issue  additional  common  units  or  preferred  units  without  common  unitholder  approval,  which  would  dilute  a 
unitholder’s existing ownership interests.

Our general partner may cause us to issue an unlimited number of common units, without common unitholder approval 
(subject to applicable New York Stock Exchange (NYSE) rules). We may also issue at any time an unlimited number of equity 
securities ranking junior or senior to the common units (including additional preferred units) without common unitholder approval 
(subject to applicable NYSE rules). In addition, we may issue additional common units upon the exercise of the outstanding 
warrants held by Blackstone and Goldentree. The issuance of additional common units or other equity securities of equal or senior 
rank will have the following effects:

• 

• 

• 

an existing unitholder’s proportionate ownership interest in NRP will decrease;

the amount of cash available for distribution on each unit may decrease; and

the relative voting strength of each previously outstanding unit may be diminished; and the market price of the common 
units may decline.

Our general partner has a limited call right that may require unitholders to sell their units at an undesirable time or price.

If at any time our general partner and its affiliates own 80% or more of the common units, the general partner will have the 
right, but not the obligation, which it may assign to any of its affiliates, to acquire all, but not less than all, of the remaining common 
units held by unaffiliated persons at a price generally equal to the then current market price of the common units. As a result, 
unitholders may be required to sell their common units at a time when they may not desire to sell them or at a price that is less 
than the price they would like to receive. They may also incur a tax liability upon a sale of their common units.

Cost reimbursements due to our general partner may be substantial and will reduce our cash available for distribution to 
unitholders.

Prior to making any distribution on the common units, we reimburse our general partner and its affiliates, including officers 
and directors of the general partner, for all expenses incurred on our behalf. The reimbursement of expenses and the payment of 
fees could adversely affect our ability to make distributions. The general partner has sole discretion to determine the amount of 
these expenses. In addition, our general partner and its affiliates may provide us services for which we will be charged reasonable 
fees as determined by the general partner.

Unitholders may not have limited liability if a court finds that unitholder actions constitute control of our business.

Our general partner generally has unlimited liability for our obligations, such as our debts and environmental liabilities, 
except for those contractual obligations that are expressly made without recourse to our general partner. Under Delaware law, 
however, a unitholder could be held liable for our obligations to the same extent as a general partner if a court determined that the 
right of unitholders to remove our general partner or to take other action under our partnership agreement constituted participation 
in the "control" of our business. In addition, Section 17-607 of the Delaware Revised Uniform Limited Partnership Act provides 
that under some circumstances, a unitholder may be liable to us for the amount of a distribution for a period of three years from 
the date of the distribution.

32

Conflicts of interest could arise among our general partner and us or the unitholders.

These conflicts may include the following:

•  Excluding our construction aggregates business, we do not have any employees and we rely solely on employees of affiliates 

of the general partner;

• 

• 

• 

• 

• 

under  our  partnership  agreement,  we  reimburse  the  general  partner  for  the  costs  of  managing  and  for  operating  the 
partnership;

the  amount  of  cash  expenditures,  borrowings  and  reserves  in  any  quarter  may  affect  cash  available  to  pay  quarterly 
distributions to unitholders;

the general partner tries to avoid being liable for partnership obligations. The general partner is permitted to protect its 
assets in this manner by our partnership agreement. Under our partnership agreement the general partner would not breach 
its fiduciary duty by avoiding liability for partnership obligations even if we can obtain more favorable terms without 
limiting the general partner’s liability;

under our partnership agreement, the general partner may pay its affiliates for any services rendered on terms fair and 
reasonable to us. The general partner may also enter into additional contracts with any of its affiliates on behalf of us. 
Agreements or contracts between us and our general partner (and its affiliates) are not necessarily the result of arm’s-length 
negotiations; and

the general partner would not breach our partnership agreement by exercising its call rights to purchase limited partnership 
interests or by assigning its call rights to one of its affiliates or to us.

In addition, as a result of the purchase of the Preferred Units, Blackstone has certain consent rights and board appointment 
and observation rights. GoldenTree also has more limited consent rights. In the exercise of their applicable consent rights and/or 
board rights, conflicts of interest could arise between us and our general partner on the one hand, and Blackstone or GoldenTree 
on the other hand.  

The control of our general partner may be transferred to a third party without unitholder consent. A change of control may 
result  in  defaults  under  certain  of  our  debt  instruments  and  the  triggering  of  payment  obligations  under  compensation 
arrangements.

Our general partner may transfer its general partner interest to a third party in a merger or in a sale of all or substantially all 
of its assets without the consent of our unitholders. Furthermore, there is no restriction in our partnership agreement on the ability 
of the general partner of our general partner from transferring its general partnership interest in our general partner to a third party. 
The new owner of our general partner would then be in a position to replace the Board of Directors and officers with its own 
choices and to control their decisions and actions.

In addition, a change of control would constitute an event of default under our debt agreements. During the continuance of 
an event of default under our debt agreements, the administrative agent may terminate any outstanding commitments of the lenders 
to extend credit to us and/or declare all amounts payable by us immediately due and payable. In addition, upon a change of control, 
the holders of the preferred units would have the right to require us to redeem the preferred units at the liquidation preference or 
convert all of their preferred units into common units. A change of control also may trigger payment obligations under various 
compensation arrangements with our officers.

Tax Risks to Our Unitholders 

Our tax treatment depends on our status as a partnership for U.S. federal income tax purposes as well as our not being subject 
to a material amount of entity-level taxation by individual states. If the Internal Revenue Service ("IRS") were to treat us as 
a corporation for federal income tax purposes or we were to become subject to material additional amounts of entity-level 
taxation for state tax purposes, then our cash available for distribution to unitholders would be substantially reduced.

The anticipated after-tax economic benefit of an investment in our units depends largely on our being treated as a partnership 
for U.S. federal income tax purposes. Despite the fact that we are organized as a limited partnership under Delaware law, we would 
be treated as a corporation for U.S. federal income tax purposes unless we satisfy a "qualifying income" requirement. Based on 
our current operations, we believe we satisfy the qualifying income requirement. However, we have not requested, and do not plan 
to request, a ruling from the IRS on this or any other matter affecting us. Failing to meet the qualifying income requirement or a 
33

change in current law could cause us to be treated as a corporation for U.S. federal income tax purposes or otherwise subject us 
to taxation as an entity.

If we were treated as a corporation for U.S. federal income tax purposes, we would pay federal income tax on our taxable 
income at the corporate tax rate and would likely be liable for state income tax at varying rates. Distributions to our unitholders 
would generally be taxed again as corporate distributions, and no income, gains, losses, deductions or credits would flow through 
to our unitholders. Because tax would be imposed upon us as a corporation, our cash available for distribution to our unitholders 
would be substantially reduced. Therefore, treatment of us as a corporation would result in a material reduction in the anticipated 
cash flow and after-tax return to our unitholders, likely causing a substantial reduction in the value of our units.

At  the  state  level,  several  states  have  been  evaluating  ways  to  subject  partnerships  to  entity-level  taxation  through  the 
imposition of state income, franchise and other forms of taxation. Imposition of a similar tax on us in a jurisdiction in which we 
operate or in other jurisdictions to which we may expand could substantially reduce the cash available for distribution to our 
unitholders.

The tax treatment of publicly traded partnerships or an investment in our units could be subject to potential legislative, judicial 
or administrative changes or differing interpretations, possibly applied on a retroactive basis.

The present U.S. federal income tax treatment of publicly traded partnerships, including us, or an investment in our units 
may be modified by administrative, legislative or judicial changes or differing interpretations at any time. From time to time, 
members of Congress propose and consider substantive changes to the existing U.S. federal income tax laws that affect publicly 
traded  partnerships. Although  there  is  no  current  legislative  proposal,  a  prior  legislative  proposal  would  have  eliminated  the 
qualifying income exception to the treatment of all publicly traded partnerships as corporations upon which we rely for our treatment 
as a partnership for U.S. federal income tax purposes.

In  addition,  on  January  24,  2017,  final  regulations  regarding  which  activities  give  rise  to  qualifying  income  within  the 
meaning of Section 7704 of the Internal Revenue Code of 1986, as amended (the "Final Regulations") were published in the Federal 
Register. The Final Regulations are effective as of January 19, 2017, and apply to taxable years beginning on or after January 19, 
2017. We anticipate that we will continue to meet the qualifying income exception for publicly traded partnership under the Final 
Regulations.

However, any interpretation of or modification to the U.S. federal income tax laws may be applied retroactively and could 
make it more difficult or impossible for us to meet the exception for certain publicly traded partnerships to be treated as partnerships 
for U.S. federal income tax purposes. We are unable to predict whether any of these changes or other proposals will ultimately be 
enacted. Any similar or future legislative changes could negatively impact the value of an investment in our units.

Certain federal income tax preferences currently available with respect to coal exploration and development may be eliminated 
as a result of future legislation.

Changes to U.S. federal income tax laws have been proposed in a prior session of Congress that would eliminate certain key 
U.S. federal income tax preferences relating to coal exploration and development. These changes include, but are not limited to 
(i) repealing capital gains treatment of coal and lignite royalties, (ii) eliminating current deductions and 60-month amortization 
for exploration and development costs relating to coal and other hard mineral fossil fuels, and (iii) repealing the percentage depletion 
allowance with respect to coal properties. If enacted, these changes would limit or eliminate certain tax deductions that are currently 
available with respect to coal exploration and development, and any such change could increase the taxable income allocable to 
our unitholders and negatively impact the value of an investment in our units. We are not aware of any current proposals with 
regard to these changes.  

Our unitholders are required to pay taxes on their share of our income even if they do not receive any cash distributions from 
us. Our unitholders' share of our portfolio income may be taxable to them even though they receive other losses from our 
activities.

Because our unitholders are treated as partners to whom we allocate taxable income that could be different in amount than 
the cash we distribute, our unitholders are required to pay any federal income taxes and, in some cases, state and local income 
taxes on their share of our taxable income even if they receive no cash distributions from us. Our unitholders may not receive cash 
distributions from us equal to their share of our taxable income or even equal to the actual tax due from them with respect to that 

34

income.

For our unitholders subject to the passive loss rules, our current operations include portfolio activities (such as our coal and 
mineral royalties business) and passive activities (such as our soda ash and aggregates businesses). Any passive losses we generate 
will only be available to offset our passive income generated in the future and will not be available to offset (i) our portfolio income, 
including income related to our coal and mineral royalties business, (ii) a unitholder’s income from other passive activities or 
investments, including investments in other publicly traded partnerships, or (iii) a unitholder’s salary or active business income. 
Thus, our unitholders' share of our portfolio income may be subject to federal income tax, regardless of other losses they may 
receive from us.

We may engage in transactions to reduce our indebtedness and manage our liquidity that generate taxable income (including 
income and gain from the sale of properties and cancellation of indebtedness income) allocable to our unitholders, and income 
tax liabilities arising therefrom may exceed any distributions made with respect to their units.

In response to current market conditions, we may engage in transactions to reduce our leverage and manage our liquidity 
that would result in income and gain to our unitholders without a corresponding cash distribution. For example, we may sell assets 
and use the proceeds to repay existing debt, in which case, our unitholders could be allocated taxable income and gain resulting 
from the sale without receiving a cash distribution. Further, we may pursue opportunities to reduce our existing debt, such as debt 
exchanges, debt repurchases, or modifications of our existing debt that would result in “cancellation of indebtedness income” (also 
referred to as “COD income”) being allocated to our unitholders as ordinary taxable income. Our unitholders may be allocated 
income and gain from these transactions, and income tax liabilities arising therefrom may exceed any distributions we make to 
our unitholders. The ultimate tax effect of any such income allocations will depend on the unitholder's individual tax position, 
including, for example, the availability of any suspended passive losses that may offset some portion of the allocable income. Our 
unitholders may, however, be allocated substantial amounts of ordinary income subject to taxation, without any ability to offset 
such allocated income against any capital losses attributable to the unitholder’s ultimate disposition of its units. Our unitholders 
are encouraged to consult their tax advisors with respect to the consequences to them

If the IRS contests the federal income tax positions we take, the market for our units may be adversely impacted and the cost 
of any IRS contest will reduce our cash available for distribution to our unitholders.

We have not requested a ruling from the IRS with respect to our treatment as a partnership for federal income tax purposes 
or any other matter affecting us. The IRS may adopt positions that differ from the positions we take. It may be necessary to resort 
to administrative or court proceedings to sustain some or all of the positions we take. A court may not agree with some or all of 
the positions we take. Any contest by the IRS may materially and adversely impact the market for our units and the price at which 
they trade. In addition, our costs of any contest by the IRS will be borne indirectly by our unitholders and our general partner 
because the costs will reduce our cash available for distribution.

If the IRS makes audit adjustments to our income tax returns for tax years beginning after December 31, 2017, it (and some 
states)  may  assess  and  collect  any  taxes  (including  any  applicable  penalties  and  interest)  resulting  from  such  audit 
adjustment directly from us, in which case our cash available for distribution to our unitholders might be substantially reduced 
and our current and former unitholders may be required to indemnify us for any taxes (including applicable penalties and 
interest) resulting from such audit adjustments that were paid on such unitholders’ behalf.

Pursuant to the Bipartisan Budget Act of 2015, for tax years beginning after December 31, 2017, if the IRS makes audit 
adjustments to our income tax returns, it (and some states) may assess and collect any taxes (including any applicable penalties 
and interest) resulting from such audit adjustment directly from us. To the extent possible under the new rules, our general partner 
may elect to either pay the taxes (including any applicable penalties and interest) directly to the IRS or, if we are eligible, issue a 
revised information statement to each unitholder with respect to an audited and adjusted return. Although our general partner may 
elect to have our unitholders take such audit adjustment into account in accordance with their interests in us during the tax year 
under audit, there can be no assurance that such election will be practical, permissible or effective in all circumstances. As a result, 
our current unitholders may bear some or all of the tax liability resulting from such audit adjustment, even if such unitholders did 
not own units in us during the tax year under audit. If, as a result of any such audit adjustment, we are required to make payments 
of taxes, penalties and interest, our cash available for distribution to our unitholders might be substantially reduced and our current 
and former unitholders may be required to indemnify us for any taxes (including any applicable penalties and interest) resulting 
from such audit adjustments that were paid on such unitholders’ behalf. These rules are not applicable for tax years beginning on 
or prior to December 31, 2017.   

35

Tax gain or loss on the disposition of our common units could be more or less than expected.

If our unitholders sell their common units, they will recognize a gain or loss equal to the difference between the amount 
realized and their tax basis in those common units. Because distributions in excess of our common unitholder's allocable share of 
our net taxable income result in a decrease in their tax basis in unitholder's common units, the amount, if any, of such prior excess 
distributions with respect to the common units they sell will, in effect, become taxable income to our common unitholders if they 
sell such common units at a price greater than their tax basis in those common units, even if the price they receive is less than their 
original cost. Furthermore, a substantial portion of the amount realized, whether or not representing gain, may be taxed as ordinary 
income due to potential recapture items, including depletion and depreciation recapture. In addition, because the amount realized 
includes a unitholder’s share of our nonrecourse liabilities, if our unitholders sell their common units, they may incur a tax liability 
in excess of the amount of cash they receive from the sale.

Our unitholders may be subject to limitation on their ability to deduct interest expense incurred by us.  

In general, we are entitled to a deduction for interest paid or accrued on indebtedness properly allocable to our trade or 
business during our taxable year. However, under the Tax Cuts and Jobs Act, for taxable years beginning after December 31, 2017, 
our deduction for “business interest” is limited to the sum of our business interest income and 30% of our “adjusted taxable income.” 
For the purposes of this limitation, our adjusted taxable income is computed without regard to any business interest expense or 
business interest income, and in the case of taxable years beginning before January 1, 2022, any deduction allowable for depreciation, 
amortization, or depletion.

Tax-exempt entities face unique tax issues from owning our units that may result in adverse tax consequences to them.

Investment in our units by tax-exempt entities, such as employee benefit plans and individual retirement accounts (known 
as IRAs) raises issues unique to them. For example, virtually all of our income allocated to organizations that are exempt from 
U.S. federal income tax, including IRAs and other retirement plans, will be unrelated business taxable income and will be taxable 
to them. Further, under the Tax Cuts and Jobs Act, for taxable years beginning after December 31, 2017, a tax-exempt entity with 
more than one unrelated trade or business (including by attribution from investment in a partnership such as ours that is engaged 
in one or more unrelated trade or business) is required to compute the unrelated business taxable income of such tax-exempt entity 
separately with respect to each such trade or business (including for purposes of determining any net operating loss deduction). 
As a result, for years beginning after December 31, 2017, it may not be possible for tax-exempt entities to utilize losses from an 
investment in our partnership to offset unrelated business taxable income from another unrelated trade or business and vice versa. 
Tax-exempt entities should consult a tax advisor before investing in our units.

Non-U.S. Unitholders will be subject to U.S. taxes and withholding with respect to their income and gain from owning our 
units.

Non-U.S. unitholders are generally taxed and subject to income tax filing requirements by the United States on income 
effectively connected with a U.S. trade or business (“effectively connected income”). Income allocated to our unitholders and any 
gain from the sale of our units will generally be considered to be “effectively connected” with a U.S. trade or business. As a result, 
distributions to a Non-U.S. unitholder will be subject to withholding at the highest applicable effective tax rate and a Non-U.S. 
unitholder who sells or otherwise disposes of a unit will also be subject to U.S. federal income tax on the gain realized from the 
sale or disposition of that unit. 

The Tax Cuts and Jobs Act imposes a withholding obligation of 10% of the amount realized upon a Non-U.S. unitholder’s 
sale or exchange of an interest in a partnership that is engaged in a U.S. trade or business. However, due to challenges of administering 
a  withholding  obligation  applicable  to  open  market  trading  and  other  complications,  the  IRS  has  temporarily  suspended  the 
application of this withholding rule to open market transfers of interests in publicly traded partnerships pending promulgation of 
regulations or other guidance that resolves the challenges. It is not clear if or when such regulations or other guidance will be 
issued. Non-U.S. unitholders should consult a tax advisor before investing in our units.

We will treat each purchaser of our common units as having the same tax benefits without regard to the actual common units 
purchased. The IRS may challenge this treatment, which could adversely affect the value of the common units.

Because we cannot match transferors and transferees of our common units and for other reasons, we have adopted depreciation 
and amortization positions that may not conform to all aspects of existing Treasury Regulations. A successful IRS challenge to 

36

those positions could adversely affect the amount of tax benefits available to our unitholders. It also could affect the timing of 
these tax benefits or the amount of gain from the sale of common units and could have a negative impact on the value of our 
common units or result in audit adjustments to our unitholders' tax returns.

We prorate our items of income, gain, loss and deduction between transferors and transferees of our common units each month 
based upon the ownership of our common units on the first day of each month, instead of on the basis of the date a particular 
unit is transferred. The IRS may challenge this treatment, which could change the allocation of items of income, gain, loss 
and deduction among our unitholders.

We generally prorate our items of income, gain, loss and deduction between transferors and transferees of our common units 
each month based upon the ownership of our common units on the first day of each month (the "Allocation Date"), instead of on 
the basis of the date a particular unit is transferred. Similarly, we generally allocate certain deductions for depreciation of capital 
additions, gain or loss realized on a sale or other disposition of our assets and, in the discretion of the general partner, any other 
extraordinary item of income, gain, loss or deduction based upon ownership on the Allocation Date. Treasury Regulations allow 
a similar monthly simplifying convention, but such regulations do not specifically authorize the use of the proration method we 
have adopted. If the IRS were to challenge our proration method, we may be required to change the allocation of items of income, 
gain, loss and deduction among our unitholders.

A unitholder whose units are the subject of a securities loan (e.g., a loan to a "short seller" to cover a short sale of units) may 
be considered as having disposed of those units. If so, he would no longer be treated for tax purposes as a partner with respect 
to those units during the period of the loan and may recognize gain or loss from the disposition.

Because there are no specific rules governing the U.S. federal income tax consequences of loaning a partnership interest, a 
unitholder whose units are the subject of a securities loan may be considered as having disposed of the loaned units. In that case, 
the unitholder may no longer be treated for tax purposes as a partner with respect to those units during the period of the loan and 
the unitholder may recognize gain or loss from such disposition. Moreover, during the period of the loan, any of our income, gain, 
loss or deduction with respect to those units may not be reportable by the unitholder and any cash distributions received by the 
unitholder as to those units could be fully taxable as ordinary income. Our unitholders desiring to assure their status as partners 
and avoid the risk of gain recognition from a loan of their units are urged to modify any applicable brokerage account agreements 
to prohibit their brokers from borrowing their units.

As a result of investing in our units, our unitholders are subject to state and local taxes and return filing requirements in 
jurisdictions where we operate or own or acquire property.

In  addition  to  federal  income  taxes,  our  unitholders  are  likely  subject  to  other  taxes,  including  state  and  local  taxes, 
unincorporated business taxes and estate, inheritance or intangible taxes that are imposed by the various jurisdictions in which we 
conduct business or own property now or in the future, even if our unitholders do not live in any of those jurisdictions. Our 
unitholders are likely required to file state and local income tax returns and pay state and local income taxes in some or all of these 
various jurisdictions. Further, our unitholders may be subject to penalties for failure to comply with those requirements. We own 
property and conduct business in a number of states in the United States. Most of these states impose an income tax on individuals, 
corporations  and  other  entities. As  we  make  acquisitions  or  expand  our  business,  we  may  own  assets  or  conduct  business  in 
additional states that impose a personal income tax. It is the unitholder's responsibility to file all U.S. federal, state and local tax 
returns.

ITEM 3.  LEGAL PROCEEDINGS 

We are involved, from time to time, in various legal proceedings arising in the ordinary course of business. While the ultimate 
results of these proceedings cannot be predicted with certainty, we believe these claims will not have a material effect on our 
financial position, liquidity or operations. We are currently involved in the litigation proceedings described below.

Foresight Energy Disputes

In November 2015, we filed a lawsuit against Foresight Energy’s subsidiary, Hillsboro Energy LLC ("Hillsboro"), in the 
Circuit Court of the Fourth Judicial Circuit in Montgomery County, Illinois. We have subsequently named Foresight Energy and 
certain of its subsidiaries in the suit. The lawsuit alleges, among other items, breach of contract by Hillsboro resulting from a 
wrongful declaration of force majeure at Hillsboro’s Deer Run mine, as well as alter-ego and tortious interference claims against 
Foresight Energy. In late March 2015, elevated carbon monoxide readings were detected at the Deer Run mine, and coal production 
at the mine was idled. In July 2015, Hillsboro declared a force majeure event under its lease with us, and Hillsboro has failed to 
make its contractually obligated minimum quarterly payments of $7.5 million since then. We believe the force majeure declaration 
has no merit and we are vigorously pursuing recovery against Hillsboro, as well as against Foresight Energy and certain of its 
other subsidiaries. Hillsboro has failed to make $76.0 million of deficiency payments to us to date, and such amount will continue 
to increase for each quarter with respect to which the payment is not made. 

In April 2016, we filed a lawsuit against Macoupin Energy, LLC ("Macoupin"), a subsidiary of Foresight Energy, in Macoupin 
County, Illinois. The lawsuit alleges that Macoupin has failed to comply with the terms of its coal mining, rail loadout and rail 
loop leases by incorrectly recouping previously paid minimum royalties. As a result, Macoupin owes NRP approximately $9.5 
million in improperly recouped minimums through December 31, 2017.

Anadarko Contingent Consideration Payment Dispute

In January 2013, we acquired a non-controlling 48.51% general partner interest in OCI Wyoming, L.P. ("OCI LP") and all 
of the preferred stock and a portion of the common stock of OCI Wyoming Co. ("OCI Co") (which in turn owned a 1% limited 
partner interest in OCI LP) from Anadarko Holding Company and its subsidiary, Big Island Trona Company (together, "Anadarko").  
The remaining general partner interest in OCI LP and common stock of OCI Co were owned by subsidiaries of OCI Chemical 
Corporation.

The acquisition agreement provided for additional contingent consideration of up to $50 million to be paid by us if certain 
performance criteria were met at OCI LP as defined in the purchase and sale agreement in any of the years 2013, 2014 or 2015. 
For those years, we paid an aggregate of $11.5 million to Anadarko in full satisfaction of these contingent consideration payment 
obligations. 

In July 2013, pursuant to a series of transactions in connection with an initial public offering by a subsidiary of OCI Chemical 
Corporation, the ownership structure in OCI LP was simplified. In connection with such reorganization, we exchanged the stock 
of OCI Co for a limited partner interest in OCI LP. Following the reorganization, our interest in OCI LP increased to 49%, consisting 
of both limited and general partner interests. The restructuring did not have any impact on the operations, revenues, management 
or control of OCI LP.

In July 2017, Anadarko filed a lawsuit against Opco and NRP Trona LLC in the District Court of Harris County, Texas, 157th 
Judicial District, alleging that the transactions conducted in 2013 triggered an acceleration of our obligation under the purchase 
agreement with Anadarko to pay additional contingent consideration in full and demanded immediate payment of such amount, 
together with interest, court costs and attorneys’ fees.  We do not believe the reorganization transactions triggered an obligation 
to pay any additional contingent consideration, and we intend to vigorously defend this lawsuit.  However, the ultimate outcome 
cannot be predicted with certainty given the early stage of this matter and we estimate a possible range of loss between $0, if we 
prevail, and approximately $40 million, plus interest, court costs and attorneys’ fees if Anadarko prevails and is awarded the full 
damages it seeks.

PURCHASES OF EQUITY SECURITIES

NRP Common Units and Cash Distributions

Our  common  units  are  listed  and  traded  on  the  NYSE  under  the  symbol  "NRP". As  of  February  1,  2018,  there  were 
approximately 20,225 beneficial and registered holders of our common units. The computation of the approximate number of 
unitholders is based upon a broker survey.

The following table sets forth the high and low sales prices per common unit, as reported on the NYSE Composite Transaction 
Tape from January 1, 2016 to December 31, 2017, and the quarterly cash distribution declared and paid per common unit with

The following table shows selected historical financial data for Natural Resource Partners L.P. for the periods and as of the

Non-GAAP Financial Measures

Distributable Cash Flow

Our Distributable Cash Flow ("DCF") represents net cash provided by operating activities of continuing operations plus 
returns of equity from unconsolidated investment, proceeds from sales of assets, including those included in discontinued operations, 
and return of long-term contract receivables (including affiliate); less maintenance capital expenditures and distributions to non-
controlling interest. DCF is not a measure of financial performance under GAAP and should not be considered as an alternative 
to cash flows from operating, investing or financing activities. DCF may not be calculated the same for us as for other companies. 
In addition, DCF presented below is not calculated or presented on the same basis as Distributable Cash Flow as defined in our 
partnership agreement, which is used as a metric to determine whether we are able to increase quarterly distributions to our common 
unitholders. DCF is a supplemental liquidity measure used by our management and by external users of our financial statements, 
such as investors, commercial banks, research analysts and others to assess the Partnership's ability to make cash distributions to 
our common and preferred unitholders and our general partner and repay debt. The following table reconciles net cash provided 
by operating activities of continuing operations (the most comparable GAAP financial measure) to Distributable Cash Flow for 
the years ended December 31, 2017, 2016, 2015, 2014, and 2013:

Adjusted EBITDA

Adjusted EBITDA is a non-GAAP financial measure that we define as net income (loss) from continuing operations less 
equity earnings from unconsolidated investment and gain on reserve swap; plus distributions from unconsolidated investment, 
interest expense, net, debt modification expense, loss on extinguishment of debt, depreciation, depletion and amortization and 
asset impairments.   

Adjusted EBITDA should not be considered an alternative to, or more meaningful than, net income or loss, net income or 
loss attributable to partners, operating income, cash flows from operating activities or any other measure of financial performance 
presented in accordance with GAAP as measures of operating performance, liquidity or ability to service debt obligations. There 
are significant limitations to using Adjusted EBITDA as a measure of performance, including the inability to analyze the effect of 
certain recurring items that materially affect our net income (loss), the lack of comparability of results of operations of different 
companies and the different methods of calculating Adjusted EBITDA reported by different companies. In addition, Adjusted 
EBITDA presented below is not calculated or presented on the same basis as Consolidated EBITDA as defined in our partnership 
agreement or Consolidated EBITDDA as defined in Opco's debt agreements. See Note 13. Debt included in the Notes to Consolidated 
Financial Statements in Item 8. "Financial Statements and Supplementary Data" included elsewhere in this Annual Report on Form 
10-K for a description of Opco’s debt agreements.

Adjusted EBITDA is a supplemental performance measure used by our management and by external users of our financial 
statements, such as investors, commercial banks, research analysts and others to assess the financial performance of our assets 
without regard to financing methods, capital structure or historical cost basis.  

The following table reconciles net income (loss) from continuing operations (the most comparable GAAP financial measure) 

to Adjusted EBITDA for the years ended December 31, 2017, 2016, 2015, 2014, and 2013:

Executive Overview 

We are a diversified natural resource company engaged principally in the business of owning, operating, managing and 
leasing a diversified portfolio of mineral properties in the United States, including interests in coal, trona and soda ash, construction 
aggregates and other natural resources. Our common units trade on the New York Stock Exchange under the symbol "NRP".

Our business is organized into three operating segments:

Coal Royalty and Other—consists primarily of coal royalty properties and coal-related transportation and processing assets. 
Other assets include aggregate, industrial mineral and oil and gas royalty properties and timber. Our coal reserves are primarily 
located in Appalachia, the Illinois Basin and the Western United States. Our aggregates and industrial minerals are primarily located 
in Pennsylvania, West Virginia, Tennessee, Kentucky and Louisiana. Our oil and gas royalty assets are primarily located in Louisiana.  

Soda Ash—consists of our 49% non-controlling equity interest in a trona ore mining operation and soda ash refinery in the 
Green River Basin, Wyoming. Ciner Resources LP, our operating partner, mines the trona, processes it into soda ash, and distributes 
the soda ash both domestically and internationally into the glass and chemicals industries. We receive regular quarterly distributions 
from this business. 

Construction Aggregates—consists of our construction materials business that operates hard rock quarries, an underground 
limestone mine, sand and gravel plants, asphalt plants and marine terminals. The construction aggregates business operates in 
Pennsylvania, West Virginia, Tennessee, Kentucky and Louisiana. 

For the year ended December 31, 2017, our consolidated financial results included:

2017 Recapitalization Transactions and Debt Reduction 

During the first quarter of 2017, we completed the recapitalization transactions that improved our liquidity and strengthened 
our balance sheet. These recapitalization transactions included the issuance of $250 million of Class A Preferred Units and the 
issuance of Warrants to purchase Common Units, and the extension of the majority of our 2018 debt maturities to 2020 and 2022. 
For more information on these transactions, see Note 3. Class A Convertible Preferred Units and Warrants and Note 13. Debt in 
the Notes to Consolidated Financial Statements under Item 8 in this Annual Report on Form 10-K, which is incorporated herein 
by reference.   

During 2017, we reduced our debt by $311.1 million. See "Liquidity and Capital Resources" below for additional information 
on our debt reduction. We remain focused on further reducing our debt, improving our credit metrics and creating long-term value 
for our stakeholders.

Metallurgical coal prices were significantly higher during 2017 as compared to the prior year driven by supply constraints 
and a 5% increase in worldwide steel production, according to data published by the World Steel Association. Increased steel 
demand  combined  with  a  reduction  in  Chinese  steel  exports  led  to  higher  steel  prices  and  steel  producer  profit  margins 
internationally, which supports higher prices for raw material inputs such as metallurgical coal and coke. Declines in Australian 
metallurgical exports due to impacts from Cyclone Debbie, logistical constraints and industry-wide operational challenges led to 
positive metallurgical coal supply and demand fundamentals. While domestic metallurgical coal production increased in 2017, 
domestic supply response was impacted by a lack of capital investment and workforce constraints. As a result of these market 
conditions, metallurgical prices in 2017 reached the highest levels since 2012. Benefiting from higher metallurgical coal prices, 
we  derived  approximately  58%  of  our  coal  royalty  revenues  and  approximately  45%  of  our  coal  royalty  production  from 
metallurgical coal during 2017. For 2018, we expect metallurgical coal markets to remain tight due to continued global economic 
growth and supportive steel industry fundamentals combined with logistical and operational supply constraints across the industry.   

Thermal coal prices in Appalachia improved over the prior year primarily as a result of increased export demand from Asia 
and northern Europe whereas Illinois Basin thermal prices remained relatively flat year over year. According to the U.S. Energy 
Information Administration, domestic electricity generation from coal decreased 3% during 2017 and was negatively impacted by 
mild weather in coal heavy regions, coal plant retirements and continued gains by renewables in the electricity generation mix. 
During 2017, thermal coal benefited from higher average natural gas prices, which increased 18%, from $2.55/mmBtu in 2016 to 
$3.02/mmBtu in 2017. Coal’s relative share of the electricity generation mix in 2017 was roughly flat at 30% of the total, while 
the relative share of natural gas declined from 34% in 2016 to 32% in 2017. As a result, domestic thermal markets were oversupplied 
in 2017 despite the relative strength in export demand and shrinking utility inventory stockpiles. During 2018, we expect domestic 
thermal coal markets to remain challenged. Long term, domestic thermal production and prices will continue to be negatively 
impacted by low natural gas prices, coal fired power plant retirements and the availability of renewable generation.

During the year ended December 31, 2017, international prices for soda ash, particularly in Asia, continued to be strong, and 
domestic prices have improved slightly over 2016. Income from this segment was slightly higher in the year ended December 31, 
2017 compared to the prior year as the effect of the increased prices noted above were offset by temporary production issues that 
were resolved in the fourth quarter of 2017. During the year ended December 31, 2017, we received distributions totaling $49.0 
million.

We expect the international market to remain strong in 2018 as a result of continued strength in Asia and a smaller than 
expected impact from the new soda ash production capacity coming on line in Turkey.  Prices, both internationally and domestically, 
are expected to remain around current levels during the year.

Construction Aggregates Business Segment

For  the  year  ended  December 31,  2017,  our  Construction Aggregates  business  segment  financial  results  included  the

Our overall construction aggregates performance in the year ended December 31, 2017 improved compared to the prior year 
primarily due to a higher production and sales of crushed stone, gravel and sand, higher delivery and haul income and increased 
road construction and asphalt paving projects. Our construction aggregates business is largely dependent on the strength of the 
local markets that it serves. In particular, key drivers of performance in the regions of our operations include: 1) natural gas drilling 
customers in the Marcellus shale, 2) traditional construction markets of Southwest Pennsylvania and Northern West Virginia, 3) 
energy-related and infrastructure spending in the Louisiana market, and 4) military spending in the Clarksville, Tennessee market.

Coal royalty revenues increased $19.0 million, or 19%, from $101.8 million in the year ended December 31, 2016 to $120.8 

million in the year ended December 31, 2017. Further discussion of the key drivers for the increase follows:  

•  Appalachia: Coal royalty revenue increased $30.7 million as a result of increased metallurgical coal prices and production.

• 

Illinois Basin: Lower production partially offset by higher royalty revenue per ton led to a $12.7 million decrease in coal 
royalty revenue. The decreased production was primarily a result of the temporary relocation of certain production off 
of  NRP's  coal  reserves,  which  resulted  in  a $7.5  million increase  in  coal  overriding  royalty  revenue  and  wheelage 
associated with the production of non-NRP coal.

Total other revenues decreased $28.0 million in 2017 compared to 2016 primarily as a result of a $33.8 million decrease in 
minimums recognized as revenue due to certain lease modifications and terminations in the second quarter 2016 and a $5.3 million
decrease in property tax reimbursements. However, the decrease in property tax revenue was fully offset by lower property tax 
expenses as described in operating and maintenance expenses below. These decreases were partially offset by an increase in coal 
override revenue as discussed above. 

Gain on coal royalty and other segment asset sales decreased $25.5 million year-over-year primarily as a result of numerous 

asset sales completed during the year ended December 30, 2016.

Revenues and other income related to our Construction Aggregates segment increased $10.9 million, or 9%, from $120.8 
million in the year ended December 31, 2016 to $131.7 million in the year ended December 31, 2017. The increase was primarily 
due to higher sales volumes.

Operating and Maintenance Expenses (including affiliates)

Operating and maintenance expenses (including affiliates) increased $6.0 million, or 5%, from $130.5 million in the year 
ended December 31, 2016 to $136.5 million in the year ended December 31, 2017. This increase is primarily related to increased
costs within our Construction Aggregates segment, partially offset by decreased costs within the Coal Royalty and Other segment.

•  Construction  Aggregates  segment  costs  increased  $11.0  million,  or  11%  from  $100.7  million  in  the  year  ended 
December 31,  2016  to  $111.6  million  in  the  year  ended  December 31,  2017. This increase is  primarily  related  to  an 
increase in production costs, repairs and maintenance and labor costs due to the increase in production and sales as 
discussed above.

•  Coal Royalty and Other segment costs decreased $5.0 million, or 17% from $29.9 million in the year ended December 31, 
2016 to $24.9 million the year ended December 31, 2017. This decrease is primarily related to $5.8 million lower property 
tax expense as a result of lower property tax rates and property tax values primarily in Kentucky and West Virginia and  
lower employee-related costs.

50

Depreciation, Depletion and Amortization ("DD&A") Expense 

DD&A expense decreased $10.3 million, or 22%, from $46.3 million in the year ended December 31, 2016 to $36.0 million
in the year ended December 31, 2017. This decrease is primarily driven by lower coal production in the Illinois Basin and $1.9 
million lower depreciation expense of construction aggregate assets due to fully depreciated assets.

General and Administrative ("G&A") Expense (including affiliates) 

Corporate  and  financing  G&A  expense  (including  affiliates)  includes  corporate  headquarters,  financing  and  centralized 
treasury and accounting. These costs decreased $2.1 million, or 10%, from $20.6 million in the year ended December 31, 2016 to 
$18.5 million in the year ended December 31, 2017. This decrease is primarily due to decreased legal, consulting and advisory 
fees incurred in 2016 as a result of the recapitalization transactions completed in March 2017.

Asset Impairments 

Asset impairments decreased $13.9 million, or 82%, from $16.9 million in the year ended December 31, 2016 to $3.0 million
in the year ended December 31, 2017. Asset impairments in the year ended December 31, 2017 primarily consisted of certain coal, 
aggregates and timber properties. Asset impairments in the year ended December 31, 2016 primarily consisted of certain coal and 
hard mineral properties. 

Interest Expense (including affiliates)

Interest expense (including affiliates) decreased $7.7 million, or 8%, from $90.6 million in the year ended December 31, 
2016 to $82.9 million in the year ended December 31, 2017. This decrease is primarily related to lower debt balances during 2017 
as a result of the recapitalization transactions entered into in March 2017.

Debt Modification Expense

Debt modification expense was $7.9 million for the year ended December 31, 2017 and related to costs incurred as a result 

of the exchange of $241 million of our 2018 Senior Notes for 2022 Senior Notes in March 2017.

Loss on Extinguishment of Debt

Loss on extinguishment of debt was $4.1 million for the year ended December 31, 2017 and related to the 4.563% premium 

paid to redeem the 2018 Senior Notes in April 2017.

Income (Loss) from Discontinued Operations 

Income from discontinued operations decreased $2.2 million, from income of $1.7 million in the year ended December 31, 
2016 to a loss of $0.5 million in the year ended December 31, 2017. The decrease is primarily a result of the sale of the discontinued 
non-operated oil and gas working interest assets in July 2016.

Adjusted EBITDA decreased $23.9 million, or 9%, from $255.4 million in the year ended December 31, 2016 to $231.5 

million in the year ended December 31, 2017. The decrease is primarily a result of the following:

•  Coal Royalty and Other segment Adjusted EBITDA decreased $28.2 million. While performance of our coal-related 
assets improved as described above, the prior year amount included $40.5 million of revenue resulting from one-time 
lease modifications and $25.5 million higher gains on asset sales.

• 

Soda Ash segment Adjusted EBITDA increased $2.5 million as a result of increased cash distributions received in the 
year ended December 31, 2017.

•  Construction Aggregates segment Adjusted EBITDA was flat in the year ended December 31, 2017 compared to 2016. 
Increased production and sales volume, increased marine terminal activity and higher margins on road construction and 
asphalt paving projects were offset by increased production costs and repairs and maintenance expenses.

•  Corporate  and  financing  Adjusted  EBITDA  increased  primarily  due  to  legal  and  consulting  fees  related  to  the 

recapitalization activities incurred in 2016.

See "Item 6. Selected Financial Data—Non-GAAP Financial Measures—Adjusted EBITDA" for an explanation of Adjusted 

EBITDA.

DCF decreased $139.3 million, or 51%, from $271.4 million in the year ended December 31, 2016 to $132.1 million in the 

year ended December 31, 2017. This decrease is due primarily to the following:

• 

$109.9 million net cash proceeds from the sale of assets included in discontinued operations in the year ended December 
31, 2016.

•  Coal Royalty and Other segment: DCF decreased $29.2 million primarily due to $61.0 million higher cash flow from 
asset  sales  in  the  year  ended  December  31,  2016  as  compared  to  2017,  partially  offset  by  $31.8  million  improved 
performance of segment assets which increased DCF in the year ended December 31, 2017.

•  Construction Aggregates segment: While operating performance was flat as described in Adjusted EBITDA above, DCF 
decreased $6.1 million due to lower operating cash flows primarily related to timing of cash receipts coupled with higher 
maintenance capital expenditures.

•  Corporate and Financing: DCF increased $3.5 million primarily as a result of lower interest, legal, consulting and advisory 

fees following the completion of the recapitalization transactions in March 2017.

Total  coal  production decreased 16.8  million tons,  or 36%,  from 47.0  million tons  in  the  year  ended December 31, 
2015 to 30.2 million tons in the year ended December 31, 2016. Total coal royalty revenues decreased $42.3 million, or 29%, 
from $144.0 million in the year ended December 31, 2015 to $101.8 million in the year ended December 31, 2016. Total coal 
56

 
production and coal royalty revenue decreases were driven by downward pressure in the coal markets as described above, with 
Central Appalachian thermal coal producers in particular continuing to face challenges, as their production costs remain high 
relative to sales prices.

Total other revenues increased $8.6 million in 2016 compared to 2015 primarily as a result of the agreements with certain 
lessees to either modify or terminate existing coal-related leases that resulted in the recognition of $40.5 million of deferred revenue. 
This increase was partially offset by non-recurring revenue transactions in 2015 that included $21.0 million in lease assignment 
fees and $9.3 million gain on reserve swap. Other revenues were also decreased $4.9 million in 2016 primarily as a result of the 
sale of our aggregates royalty assets in the first quarter of 2016.

Gain on coal royalty and other segment asset sales increased $22.1 million primarily as a result of the following asset sales 

during the first quarter of 2016:

1)  Oil and gas royalty and overriding royalty interests in several producing properties located in the Appalachian Basin for 
$36.4 million gross sales proceeds. The effective date of the sale was January 1, 2016, and we recorded an $18.6 million 
gain from this sale.

2)  Aggregate reserves and related royalty rights in the Coal Royalty and Other segment at three aggregates operations located 
in Texas, Georgia and Tennessee for $10.0 million gross sales proceeds. The effective date of the sale was February 1, 
2016, and we recorded a $1.5 million gain from this sale.

Soda Ash

Revenues and other income related to our equity investment in Ciner Wyoming decreased $9.8 million, or 20%, from $49.9 
million in the year ended December 31, 2015 to $40.1 million in the year ended December 31, 2016. This decrease is primarily 
related to lower international prices compared to the prior year, in addition to higher royalty and G&A costs. These decreases were 
partially offset by an increase in soda ash volumes sold compared to the prior year.

Revenues and other income related to our Construction Aggregates segment decreased $18.2 million, or 13%, from $139.0 
million in the year ended December 31, 2015 to $120.8 million in the year ended December 31, 2016. This decrease is primarily 
due to a decrease in construction aggregates and brokered stone revenue as well as lower delivery and fuel income year-over-year. 
Tonnage  sold  by  the  Construction  Aggregates  segment decreased 0.4  million tons,  or 5% from 7.4  million tons  in the  year 
ended December 31, 2015 to 7.0 million tons in the year ended December 31, 2016 as a result of decreased construction aggregates 
demand in the oil and gas services sector that was partially offset by increased aggregates sales into the construction market.

Operating and Maintenance Expenses (including affiliates)

Operating and maintenance expenses (including affiliates) decreased $21.8 million, or 14%, from $152.3 million in the year 
ended December 31,  2015 to $130.5  million in the  year  ended December 31,  2016.  Operating  and  maintenance  expenses 
(including affiliates) in our Construction Aggregates segment decreased $16.2 million, or 14% from $116.9 million in the year 
ended December 31, 2015 to $100.7 million in the year ended December 31, 2016. This decrease is primarily due to the decline 
in materials cost as a result of the decrease in construction aggregates and brokered stone volume year-over-year due to reduced 
demand in the oil and gas sector and a decrease in delivery and fuel costs due to the lower construction aggregates production and 
brokered stone purchases year-over-year partially and effective variable cost management.

Depreciation, Depletion and Amortization ("DD&A") Expense

DD&A  expense decreased $14.6  million,  or 24%,  from $60.9  million in the  year  ended December 31,  2015 to $46.3 
million in the year ended December 31, 2016. This decrease is primarily related to the reduced cost basis of our coal and aggregates 
royalty mineral rights due to the asset impairments recorded in the third and fourth quarters of 2015 and the decline in coal royalty 
production year-over-year.

General and Administrative ("G&A") Expense (including affiliates) 

Corporate  and  financing  G&A  expense  (including  affiliates)  includes  corporate  headquarters,  financing  and  centralized 
treasury  and  accounting.  These  costs increased $8.3  million,  or 67%,  from $12.3  million in the  year  ended December 31, 
2015 to $20.6 million in the year ended December 31, 2016. This increase is primarily related to increased legal and consulting 
fees associated with the implementation of our long-term plan to strengthen our balance sheet, reduce debt and enhance our liquidity 
and increased LTIP expense as a result of our unit price increasing in 2016 compared to decreasing unit price in 2015 and the 
accelerated recognition of our LTIP awards granted in 2016

Asset Impairment

Asset impairments decreased $367.6 million, or 96%, from $384.5 million in the year ended December 31, 2015 to $16.9 
million in the year ended December 31, 2016. We recorded the following asset impairments during the years ended December 31, 
2016 and 2015:

Asset impairments decreased $362.4 million, or 96%, from $378.3 million in the year ended December 31, 2015 to $15.9 
to $257.5  million in  coal  property 
million in the  year  ended December 31,  2016.  This decrease is  primarily  related 
impairment, $70.5  million in  oil  and  gas  property  impairment  and $43.4  million in  aggregate  property  impairment  recorded 
during the year ended December 31, 2015 as compared to $12.1 million in coal property impairment and $1.7 million in aggregate 
property impairment recorded during the year ended December 31, 2016. The impairments in 2015 primarily resulted from the 
continued deterioration and expectations of further reductions in global and domestic coal demand due to reduced global steel 
demand, sustained low natural gas prices, and continued regulatory pressure on the electric power generation industry.

Construction Aggregates

Asset  impairments decreased $5.1  million,  or 82%,  from $6.2  million in the  year  ended December 31,  2015 to $1.1 
million in the year ended December 31, 2016. This decrease is primarily related to the $5.5 million write off of goodwill during 
the year ended December 31, 2015.

58

Income (Loss) from Discontinued Operations 

Income from discontinued operations increased $313.2 million, from a loss of $311.5 million in the year ended December 31, 
2015 to income of $1.7 million in the year ended December 31, 2016. The change in income (loss) from discontinued operations 
is primarily related to the $297.0 million asset impairments recorded in 2015, the sale of our non-operated oil and gas working 
interest assets that was completed in July 2016 with an effective date of April 1, 2016 and the $8.3 million gain on sale for the 
year ended December 31, 2016.

Adjusted  EBITDA decreased $7.1  million,  or 3%,  from $262.6  million in the  year  ended December 31,  2015 to $255.5 
million in the year ended December 31, 2016. The decrease is primarily a result of $42.3 million in reduced coal royalty revenue 
resulting from decreased coal production and coal royalty revenue per ton driven by the continued pressure on U.S. coal producers 
as described above, $21.0 million in non-recurring 2015 lease assignment fees, $4.9 million of reduced aggregates royalty revenue 
in 2016 due to decreased 2016 aggregates production and sales and $8.3 million of additional G&A expense in 2016 compared to 
2015 as described above. These decreases were partially offset by a $49.1 million increase in minimums recognized as revenue 
primarily as a result of coal lease modifications or terminations that resulted in our lessee forfeiting their minimum royalty balances 
and $22.2 million of additional gains on asset sales as compared to the same period in 2015. See "Item 6. Selected Financial Data
—Non-GAAP Financial Measures—Adjusted EBITDA" for an explanation of Adjusted EBITDA.

DCF increased $94.8 million, or 54%, from $176.6 million in the year ended December 31, 2015 to $271.4 million in the 
year  ended December 31,  2016.  This increase is  due  primarily  to  the $109.9  million net  cash  proceeds  from  the  sale  of  our 
discontinued operation in addition to $61.0 million in net cash proceeds from sales of mineral rights in 2016. These increases were 
partially offset by lower coal royalty production, lower coal royalty revenue per ton and less minimum payments received from 
our coal leases. These decreases are driven by the continued pressure on U.S. coal producers as described above. See "Item 6. 
Selected Financial Data—Non-GAAP Financial Measures—Distributable Cash Flow" for an explanation of Distributable Cash 
Flow.

Liquidity and Capital Resources

Current Liquidity 

The principal indicators of our liquidity are our cash on hand and our available borrowing capacity. As of December 31, 
2017, we had a total of $29.8 million of cash and cash equivalents and $90.0 million in borrowing capacity under our Opco Credit 
Facility. During the year ended December 31, 2017, we reduced our debt by approximately $311.1 million as summarized in the 
table below:

Additionally, in March 2017, we issued $250 million of Class A Convertible Preferred Units representing limited partner 
interests in NRP (the "Preferred Units"). The Preferred Units entitle the Preferred Purchasers to receive cumulative distributions 
at a rate of 12% per year, up to one half of which we may pay in additional Preferred Units (such additional Preferred Units, the 
"PIK Units"). For more information on the terms of the Preferred Units, see Note 3. Class A Convertible Preferred Units and 
Warrants in the Notes to Consolidated Financial Statements under Item 8 in this Annual Report on Form 10-K, which is incorporated 
herein by reference. During 2017, we declared $17.7 million in distributions on the Preferred Units, one-half of which were paid 
in cash. In February 2018, we paid the entire $7.8 million distribution on the Preferred Units in cash and redeemed all of the 
outstanding PIK Units, which resulted in an additional $8.8 million cash payment. 

The March 2017 recapitalization transactions increased our liquidity and extended the majority of our 2018 debt maturities 
to 2020 and 2022. Even with these meaningful improvements to our liquidity and balance sheet, we continue to have substantial 
debt outstanding and intend to continue to use cash from operations to deleverage our balance sheet over time. While we have a 
diversified portfolio of assets, we face challenges in coal and other commodity markets and other factors, some of which are beyond 
our control. 

Cash Flows 

Cash flow provided by operating activities increased $19.2 million, from $108.0 million in the year ended December 31, 
2016  to  $127.1  million  in  the  year  ended  December  31,  2017.  Cash  flows  from  continuing  operations  increased $27.2 
million primarily from increased operational performance from our Coal Royalty and Other segment assets year-over-year. This 
increase was partially offset by an $8.0 million decrease in operating cash flow from discontinued operations. Cash flows from 
discontinued operations represent cash flow from operations of these assets prior to the sale date.

Cash flow provided by operating activities decreased $95.4 million, from $203.4 million in the year ended December 31, 
2015 to $108.0 million in the year ended December 31, 2016. Operating cash flow from continuing operations decreased $70.4 
million in our Coal Royalty and Other segment year-over-year primarily as a result of the reduction in coal royalty revenue and 
reduction  of  coal  royalty  minimum  cash  payments  received  on  certain  leases.  Cash  flow  provided  by  operating  activities  of 
discontinued operations decreased $27.6 million, from $34.9 million in the year ended December 31, 2015 to $7.3 million in the 
year ended December 31, 2016 primarily as a result of completing the sale of our non-operated oil and gas working interest assets 
in July 2016 that had an effective date of April 1, 2016.

Cash flow provided by investing activities decreased $163.3 million, from $166.8 million in the year ended December 31, 
2016 to $3.5 million in the year ended December 31, 2017. Investing cash flows from discontinued operations decreased $106.7 
million primarily as a result of the sale of our non-operated oil and gas working interest assets in 2016 for $109.9 million in net 

62

cash  proceeds.  Investing  cash  flows  from  continuing  operations decreased $56.6  million primarily  as  a  result  of  the  proceeds 
received in 2016 from the sales of our oil and gas and aggregates royalty properties.

Cash flow provided by investing activities increased $197.1 million, from $30.3 million used in the year ended December 
31, 2015 to $166.8 million provided in the year ended December 31, 2016. Investing cash flows from discontinued operations 
increased $144.2 million primarily as a result of the sale of our non-operated oil and gas working interest assets in July 2016 
for $109.9 million in net cash proceeds in addition to a $37.8 million decrease in cash flow used as a result of lower oil and gas 
drilling activity and the non-operated working interest asset sale in July 2016. Investing cash flows from continuing operations 
increased $52.9 million primarily as a result of 2016 sales of oil and gas and aggregate royalty properties.

Cash flow used in financing activities decreased $145.0 million from $286.2 million in the year ended December 31, 2016 
to $141.2 million in the year ended December 31, 2017. This decrease in cash flow used is primarily due to the proceeds received 
from the issuance of Preferred Units and warrants and 2022 Senior Notes. These proceeds were partially offset by additional debt 
repayments year-over-year and the fees paid related to the March 2017 recapitalization transactions.

Cash flow used in financing activities increased $114.7 million, from $171.5 million in the year ended December 31, 2015 
to $286.2  million in  the  year  ended  December  31,  2016.  Cash  used  in  financing  activities  of  discontinued  operations 
increased $136.6 million primarily as a result of using $85.0 million to repay the RBL Credit Facility and contributing the $39.4 
million of discontinued asset sales proceeds that remained after repayment of the RBL Facility in full to continuing operations. 
This increase in cash flow used in financing activities was partially offset by a $21.9 million decrease in cash flow used in financing 
activities from continuing operations primarily a result of distributing $49.3 million less cash to partners and receiving the remaining 
net proceeds from discontinuing operations after repayment as described above.

Capital Expenditures

A  portion  of  the  capital  expenditures  associated  with  our  construction  aggregates  segment  are  maintenance  capital 
expenditures, which are capital expenditures made to maintain the long-term production capacity of those businesses. Expansion 
capital expenditures are made to increase productive capacity. We deduct maintenance capital expenditures when calculating DCF.

Shelf Registration Statement

In September 2015, we filed a registration statement on Form S-3 with the SEC that is available for registered offerings of 
common units. In April 2017, we filed a shelf registration statement on Form S-3 with the SEC to register the common units 
issuable upon conversion of the warrants, as described above. 

Off-Balance Sheet Transactions

We do not have any off-balance sheet arrangements with unconsolidated entities or related parties and accordingly, there are 

no off-balance sheet risks to our liquidity and capital resources from unconsolidated entities.

Inflation

Inflation in the United States has been relatively low in recent years and did not have a material impact on operations for 

the years ended December 31, 2017, 2016 and 2015.

Summary of Critical Accounting Estimates

Preparation of the accompanying financial statements in conformity with accounting principles generally accepted in the 
United  States  requires  management  to  make  estimates  and  assumptions  that  affect  the  reported  amounts  of  assets,  liabilities, 
revenues and expenses. See Note 2. Summary of Significant Accounting Policies to the audited consolidated financial statements 
under Item 8 of this Form 10-K for discussion of our significant accounting policies. The following critical accounting policies 
are affected by estimates and assumptions used in the preparation of Consolidated Financial Statements. We evaluate our estimates 
and assumptions on a regular basis. Actual results could differ from those estimates.

Revenues

Coal Royalty and Other Revenues.     Coal royalty and other revenues are recognized on the basis of tons of mineral sold by 
our lessees and the corresponding revenue from those sales. Generally, the lessees make payments to us based on the greater of a 
percentage of the gross sales price or a fixed price per ton of mineral they sell. While we may have multiple contracts with a single 
lessee, they are accounted for as separate arrangements.

Most of our coal and aggregates lessees must make minimum annual or quarterly payments which are generally recoupable 
over certain time periods. These minimum payments are recorded as a deferred revenue liability when received. The deferred 
revenue attributable to the minimum payment is recognized as revenue based upon the underlying mineral lease when the lessee 
recoups the minimum payment through production or in the period immediately following the expiration of the lessee’s ability to 
recoup the payments.

Oil and gas related revenues consist of revenues from royalties and overriding royalties. Oil and gas royalty revenues are 

recognized on the basis of volume of hydrocarbons sold by lessees and the corresponding revenue from those sales. 

Transportation and Processing.     Transportation fees are recognized on the basis of tons of material transported over the 
beltlines. Under the terms of the transportation contracts, we receive a fixed price per ton for all material transported on the beltlines. 
Processing fees are recognized on the basis of tons of material processed through the facilities by our lessees and the corresponding 
revenue from those sales. Generally, the lessees of the processing facilities make payments to us based on the greater of a percentage 
of the gross sales price or a fixed price per ton of material that is processed and sold from the facilities. The processing leases are 
structured in a manner so that the lessees are responsible for operating and maintenance expenses associated with the facilities. 
These fees are recorded in Transportation and processing fees (or Transportation and processing fees-affiliate) in the Consolidated 
Statements of Comprehensive Income (Loss).

Equity  in  Earnings  of  Ciner  Wyoming.  We  account  for  non-marketable  equity  investments  using  the  equity  method  of 
accounting if the investment gives us the ability to exercise significant influence over, but not control of, an investee. Significant 
influence generally exists if we have an ownership interest representing between 20% and 50% of the voting stock of the investee. 
We account for our investment in Ciner Wyoming using this method.

Under the equity method of accounting, investments are stated at initial cost and are adjusted for subsequent additional 
investments and the proportionate share of earnings or losses and distributions. The basis difference between the investment and 
the proportional share of the investee's net assets is hypothetically allocated first to identified tangible assets and liabilities, then 
to finite-lived intangibles or indefinite-lived intangibles and the remaining balance is attributed to goodwill. The portion of the 
basis  difference  attributed  to  net  tangible  assets  and  finite-lived  intangibles  is  amortized  over  its  estimated  useful  life  while 
indefinite-lived  intangibles,  if  any,  and  goodwill  are  not  amortized. The  amortization  of  the  basis  difference  is  recorded  as  a 
reduction of earnings from the equity investment in the Consolidated Statements of Comprehensive Income (Loss).

Our carrying value in an equity method investee company is reflected in the caption "Equity in unconsolidated investment" 
in our  Consolidated Balance Sheets.  Our adjusted share  of the earnings  or losses  of the investee company is  reflected in  the 
Consolidated Statements of Comprehensive Income (Loss) as revenues and other income under the caption ‘‘Equity in earnings 
of Ciner Wyoming." Our share of investee earnings are adjusted to reflect the amortization of any difference between the cost basis 
of the equity investment and the proportionate share of the investee’s net assets, which has been allocated to the fair value of net 
identified tangible and finite-lived intangible assets and amortized over the estimated lives of those assets.

Construction Aggregates Revenues.     Revenues from the sale of aggregates, gravel, sand and asphalt are recorded based 

upon the transfer of product at delivery to customers, which generally occurs at the quarries or asphalt plants. 

65

Road Construction and Asphalt Paving.     Revenues from long-term construction contracts are recognized on the percentage-
of-completion method, measured by the percentage of total costs incurred to date to the estimated total costs for each contract. 
That method is used since we consider total cost to be the best available measure of progress on the contracts. Provisions for 
estimated losses on uncompleted contracts are made in the period in which such losses are determined. Changes in job performance, 
job conditions and estimated profitability, including those arising from final contract settlements, which result in revisions to job 
costs and profits are recognized in the period in which the revisions are determined. Contract costs include all direct job costs and 
those  indirect  costs  related  to  contract  performance,  such  as  indirect  labor,  supplies,  insurance,  equipment  maintenance  and 
depreciation. 

Impact of New Revenue Recognition Standard Adoption.  We concluded that the new revenue recognition standard (Topic 
606) will have no impact on revenue from our Construction Aggregates or Soda Ash operating segments. However, we determined 
that adoption of the new revenue recognition standard will impact certain revenue from our coal royalty leases as further described 
below. The other revenue streams within the Coal Royalty and Other segment will not be impacted.

Under the new revenue recognition standard (Topic 606), we have defined our coal royalty lease performance obligation as 
providing the lessee the right to mine and sell our coal over the lease term. We then evaluated the likelihood that consideration we 
received from our lessees resulting from coal production would exceed consideration received from minimum payments over the 
lease term. As a result of this evaluation, revenue recognition from our leases will now be based on either production or minimum 
payments as follows:

1.  Production Leases:  Leases for which we expect that consideration from coal production will be greater than 
consideration from minimums over the lease term. Revenue recognition for these leases will be recognized over time 
based on coal production and minimum payments will continue to be deferred until recoupment occurs or the recoupment 
becomes remote. However, if we receive minimum payments from these coal royalty leases, we will begin to evaluate 
the likelihood of recoupment and recognize deferred revenue prior to expiration of the recoupment period if it concludes 
that recoupment is remote. 

2.  Minimum  Leases:    Leases  for  which  we  expect  that  consideration  from  minimums  will  be  greater  than 
consideration from coal production over the lease term. Revenue recognition for these leases will now be recognized 
straight line over the lease term based on the minimum payment consideration amount. 

Mineral Rights

Mineral rights owned and leased are recorded at its original cost of construction or, upon acquisition, at fair value of the 
assets acquired. Coal and aggregate mineral rights are depleted on a unit-of-production basis by lease, based upon minerals mined 
in relation to the net cost of the mineral properties and estimated proven and probable tonnage as defined by the SEC’s Industry 
Guide 7 and estimated by our internal reserve engineers. The technologies and economic data used by our internal reserve engineers 
in the estimation of our proved reserves include, but are not limited to, drill logs, geophysical logs, geologic maps including 
isopach,  mine,  and  coal  quality,  cross  sections,  statistical  analysis,  and  available  public  production  data. There  are  numerous 
uncertainties inherent in estimating the quantities and qualities of recoverable reserves, including many factors beyond our control. 
Estimates of economically recoverable coal reserves depend upon a number of variable factors and assumptions, any one of which 
may, if incorrect, result in an estimate that varies considerably from actual results. 

Asset Impairment

We have developed procedures to periodically evaluate our long-lived assets for possible impairment. These procedures are 
performed throughout the year and are based on historic, current and future performance and are designed to be early warning 
tests. If an asset fails one of the early warning tests, additional evaluation is performed for that asset that considers both quantitative 
and qualitative information. A long-lived asset is deemed impaired when the future expected undiscounted cash flows from its use 
and disposition is less than the assets’ carrying value. Impairment is measured based on the estimated fair value, which is usually 
determined based upon the present value of the projected future cash flow compared to the assets’ carrying value. We believe our 
estimates of cash flows and discount rates are consistent with those of principal market participants. In addition to the evaluations 
discussed above, specific events such as a reduction in economically recoverable reserves or production ceasing on a property for 
an extended period may require a separate impairment evaluation be completed on a significant property. 

66

We evaluate our equity investment for impairment when events or changes in circumstances indicate, in management’s 
judgment,  that  the  carrying  value  of  such  investment  may  have  experienced  an  other-than-temporary  decline  in  value. When 
evidence of loss in value has occurred, management compares the estimated fair value of the investment to the carrying value of 
the  investment  to  determine  whether  impairment  has  occurred.  If  the  estimated  fair  value  is  less  than  the  carrying  value  and 
management considers the decline in value to be other than temporary, the excess of the carrying value over the estimated fair 
value is recognized in the financial statements as an impairment loss. The fair value of the impaired investment is based on quoted 
market prices, or upon the present value of expected cash flows using discount rates believed to be consistent with those used by 
principal market participants, plus market analysis of comparable assets owned by the investee, if appropriate.

Recent Accounting Standards

For  a  discussion  of  recent  accounting  pronouncements,  see  the  applicable  section  of  "Item  8.  Financial  Statements  and 
Supplementary  Data—Note  2.  Summary  of  Significant Accounting  Policies"  to  the  audited  consolidated  financial  statements 
included elsewhere in this Annual Report on Form 10-K.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We are exposed to market risk, which includes adverse changes in commodity prices and interest rates as discussed below:

Commodity Price Risk

We are dependent upon the effective marketing of the coal mined by our lessees. Our lessees sell the coal under various 
long-term and short-term contracts as well as on the spot market. Current conditions in the coal industry may make it difficult for 
our lessees to extend existing contracts or enter into supply contracts with terms of one year or more. Our lessees’ failure to negotiate 
long-term contracts could adversely affect the stability and profitability of our lessees’ operations and adversely affect our coal 
royalty revenues. If more coal is sold on the spot market, coal royalty revenues may become more volatile due to fluctuations in 
spot coal prices.

We have market risk related to prices for our aggregates products. Aggregates prices are primarily driven by economic 

conditions in the local markets in which the products are sold.

The market price of soda ash directly affects the profitability of Ciner Wyoming’s operations. If the market price for soda 
ash declines, Ciner Wyoming’s sales will decrease. Historically, the global market and, to a lesser extent, the domestic market for 
soda ash have been volatile, and those markets are likely to remain volatile in the future.

Interest Rate Risk

Our exposure to changes in interest rates results from our borrowings under the Opco Credit Facility, which is subject to 
variable interest rates based upon LIBOR. At December 31, 2017, we had $60.0 million outstanding in variable interest rate debt. 
If interest rates were to increase by 1%, annual interest expense would increase approximately $0.6 million, assuming the same 
principal amount remained outstanding during the year.

67

Fair Value of Financial Instruments

Our financial instruments consist of cash and cash equivalents, accounts receivable, contracts receivable, accounts payable, 
debt, Preferred Units and warrants. The carrying amounts reported on the Consolidated Balance Sheets for cash and cash equivalents, 
accounts receivable and accounts payable approximate fair value due to their short-term nature. 

We use available market data and valuation methodologies to estimate the fair value of debt. The fair value of debt is the 
estimated amount we would have to pay a third party to assume the debt, including a credit spread for the difference between the 
issue rate and the period end market rate. The credit spread is our default or repayment risk. The following table shows the carrying 
amount and estimated fair value of our debt and contracts receivable (including affiliates):

(2)  Due to no observable quoted prices on these instruments, the Level 3 fair value is estimated by management using quotations 

obtained for the NRP Senior Notes on the closing trading prices near period end.

(3)  The Level 3 fair value approximates the outstanding borrowing amount because the interest rates are variable and reflective 
of market rates and the terms of the credit facility allow the Partnership to repay this debt at any time without penalty.

(4)  The Level 3 fair value  is determined based on the present value of future cash flow projections related to the underlying

Report of Independent Registered Public Accounting Firm

The Partners of Natural Resource Partners L.P.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Natural Resource Partners L.P. (the Partnership) as of December 
31, 2017 and 2016, and the related consolidated statements of comprehensive income (loss), partners’ capital and cash flows for 
each of the three years in the period ended December 31, 2017, and the related notes (collectively referred to as the “consolidated 
financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial 
position of the Partnership at December 31, 2017 and 2016, and the results of its operations and its cash flows for each of the  three 
years in the period ended December 31, 2017, in conformity with U.S. generally  accepted accounting principles.

We did not audit the financial statements of Ciner Wyoming LLC (Ciner Wyoming), a Limited Liability Company in which the 
Partnership has a 49% interest. In the consolidated financial statements, the Partnership’s investment in Ciner Wyoming is stated 
at $245 million and $256 million as of December 31, 2017 and 2016, respectively, and the Partnership’s equity in the net income 
of Ciner Wyoming is stated at $40 million in 2017, $40 million in 2016 and $50 million in 2015. Those statements were audited 
by other auditors whose report has been furnished to us, and our opinion, insofar as it relates to the amounts included for Ciner 
Wyoming, is based on the report of the other auditors.

We  also  have  audited,  in  accordance  with  the  standards  of  the  Public  Company Accounting  Oversight  Board  (United  States) 
(PCAOB), the Partnership's internal control over financial reporting as of December 31, 2017, based on criteria established in 
Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 
framework), and our report dated March 1, 2018 expressed an unqualified opinion thereon.

Adoption of ASU 2017-11

As discussed in Note 2 to the consolidated financial statements, the Partnership changed its method for accounting for warrants 
to purchase common units as a result of the adoption of the amendments to the FASB Accounting Standards Codification resulting 
from Accounting Standards Update No. 2017-11, “Earnings Per Share.”

Basis for Opinion

These financial statements are the responsibility of the Partnership's management. Our responsibility is to express an opinion on 
the Partnership’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are 
required to be independent with respect to the Partnership in accordance with the U.S. federal securities laws and the applicable 
rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the 
audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error 
or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether 
due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, 
evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting 
principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial 
statements. We believe that our audits and the report of other auditors provide a reasonable basis for our opinion.

NATURAL RESOURCE PARTNERS L.P.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.    Organization and Nature of Operations

Natural Resource Partners L.P. (the "Partnership"), a Delaware limited partnership, was formed in April 2002. The general 
partner of the Partnership is NRP (GP) LP ("NRP GP"), a Delaware limited partnership, whose general partner is GP Natural 
Resource Partners LLC, a Delaware limited liability company. The Partnership engages principally in the business of owning, 
operating, managing and leasing a diversified portfolio of mineral properties in the United States, including interests in coal, trona 
and soda ash, construction aggregates and other natural resources and is organized into three operating segments further described 
in Note 6. Segment Information. As used in these Notes to Consolidated Financial Statements, the terms "NRP," "we," "us" and 
"our" refer to Natural Resource Partners L.P. and its subsidiaries, unless otherwise stated or indicated by context.

The Partnership’s operations are conducted through, and its operating assets are owned by, its subsidiaries. The Partnership 
owns  its  subsidiaries  through  one  wholly  owned  operating  company,  NRP  (Operating)  LLC  ("Opco").  NRP  GP  has  sole 
responsibility for conducting the Partnership's business and for managing its operations. Because NRP GP is a limited partnership, 
its general partner, GP Natural Resource Partners LLC, conducts its business and operations, and the board of directors and officers 
of GP Natural Resource Partners LLC makes decisions on its behalf. Robertson Coal Management LLC ("RCM"), a limited liability 
company wholly owned by Corbin J. Robertson, Jr., owns all of the membership interest in GP Natural Resource Partners LLC. 
Subject to the Board Representation and Observation Rights Agreement with certain entities controlled by funds affiliated with 
The  Blackstone  Group,  L.P.  (collectively  referred  to  as  "Blackstone")  and  affiliates  of  GoldenTree Asset  Management  LP 
(collectively referred to as "GoldenTree"), RCM is entitled to appoint the directors of the Board of Directors of GP Natural Resource 
Partners LLC. RCM has delegated the right to appoint one director to Blackstone.

2.    Summary of Significant Accounting Policies

Basis of Presentation

The accompanying Consolidated Financial Statements of the Partnership have been prepared in accordance with generally 
accepted accounting principles in the United States of America ("GAAP"). The consolidated financial statements include the 
accounts of Natural Resource Partners L.P. and its wholly owned subsidiaries, as well as BRP LLC ("BRP"), a joint venture with 
International Paper Company controlled by the Partnership. The Partnership has an equity investment through which it is able to 
exercise significant influence over but does not control the investee and is not the primary beneficiary of the investee’s activities 
and  is  accounted  for  using  the  equity  method.  Intercompany  transactions  and  balances  have  been  eliminated.  Certain 
reclassifications  have  been  made  to  prior  year  amounts  on  the  Consolidated  Balance  Sheets,  Consolidated  Statements  of 
Comprehensive Income (Loss) and Statements of Cash Flows to conform with current year presentation. These reclassifications 
have no impact on previously reported assets, liabilities, total revenues and other income, net income (loss), or cash flows from 
operations, investing or financing.

Use of Estimates

Preparation of the accompanying financial statements in conformity with GAAP requires management to make estimates 
and assumptions that affect the reported amounts of assets and liabilities in the accompanying Consolidated Balance Sheets, the 
disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and 
expenses in the accompanying Consolidated Statements of Comprehensive Income (Loss) during the reporting period. Actual 
results could differ from those estimates.  The most significant estimates pertain to coal and aggregate reserves and related cash 
flow estimates which are used to compute depreciation, depletion and amortization and impairments of coal and aggregate properties 
and commitments and contingencies. 

77

NATURAL RESOURCE PARTNERS L.P.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—CONTINUED

Fair Value

The Partnership discloses certain assets and liabilities using fair value as defined by authoritative guidance. Fair value is 
defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market 
participants at the measurement date. See Note 14. Fair Value Measurements.

There are three levels of inputs that may be used to measure fair value:

•  Level 1—Quoted prices in active markets for identical assets or liabilities.

•  Level 2—Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices 
in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for 
substantially the full term of the assets or liabilities.

•  Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value 
of the assets or liabilities. Level 3 assets and liabilities include financial instruments whose value is determined using 
pricing  models,  discounted  cash  flow  methodologies,  or  similar  techniques,  as  well  as  instruments  for  which  the 
determination of fair value requires significant management judgment or estimation.

Cash and Cash Equivalents

The Partnership considers all highly liquid short-term investments with an original maturity of three months or less to be 

cash equivalents.

Allowance for Doubtful Accounts

Accounts receivable are recorded net of the allowance for doubtful accounts. The Partnership records an allowance for 
doubtful accounts for receivables which it determines to be uncollectible based on the specific identification method. Accounts 
are written off when collection efforts are exhausted and future recovery is doubtful. The allowance for doubtful accounts included 
in the Partnership's net accounts receivable balance (including affiliates) was $5.1 million and $4.6 million at December 31, 2017
and December 31, 2016, respectively. A significant amount of the Partnership's allowance for doubtful accounts relates to coal-
related receivables. The Partnership recorded bad debt expense of $2.4 million, $0.4 million and $4.9 million, respectively, included 
in Operating and maintenance expense (including affiliates) on its Consolidated Statements of Comprehensive Income (Loss) for 
the years ended December 31, 2017, 2016 and 2015, respectively.  

Inventory

Inventories are comprised of aggregates and supplies and parts and are stated at the lower of cost or net realizable value. 
The cost of aggregates and asphalt components such as stone, sand, and recycled and liquid asphalt is determined by the first-in, 
first-out (FIFO) method. Cost includes all direct materials, direct labor and related production overheads based on normal operating 
capacity. The cost of supplies and parts inventory is determined by the average cost method and includes operating and maintenance 
supplies to be used in the Partnership’s aggregates operations.

Plant and Equipment

Plant and equipment is recorded at its original cost of construction or, upon acquisition, at fair value of the asset acquired 
and consists of coal preparation plants, related coal handling facilities, and other coal and aggregate transportation and processing 
infrastructure. Expenditures for new facilities or that substantially increase the useful life of property, including interest during 
construction, are capitalized and reported in the Consolidated Statements of Cash Flows. These assets are depreciated on a straight-
line basis over their useful lives generally as follows: 

Buildings and improvements
Machinery and equipment
Leasehold improvements

Years

20 to 40
5 to 12
Life of Lease

78

 
NATURAL RESOURCE PARTNERS L.P.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—CONTINUED

The Partnership begins capitalizing costs for construction in process and mine development at its aggregates operations at 
a point when reserves are determined to be proven or probable, economically mineable and when demand supports investment in 
the market. Once production commences, capitalization of such costs ceases. Mine development costs are amortized based on 
production over the estimated life of mineral reserves and amortization is included as a component of depreciation expense.

Mineral Rights

Mineral rights owned and leased are recorded at its original cost of construction or, upon acquisition, at fair value of the 
assets acquired. Coal and aggregate mineral rights are depleted on a unit-of-production basis by lease, based upon minerals mined 
in relation to the net cost of the mineral properties and estimated proven and probable tonnage therein. 

Intangible Assets

The Partnership’s intangible assets consist primarily of contracts that at acquisition were more favorable for the Partnership 
than prevailing market rates, known as above-market contracts. The estimated fair values of the above-market rate contracts are 
determined based on the present value of future cash flow projections related to the underlying assets acquired. Intangible assets 
are amortized on a unit-of-production basis except that a minimum amortization is calculated on a straight-line basis over the 
remaining term of the underlying lease for temporarily idled assets.

Asset Impairment

The Partnership has developed procedures to evaluate its long-lived assets for possible impairment periodically or whenever 
events or changes in circumstances indicate an asset's carrying amount may not be recoverable. These procedures are performed 
throughout  the  year  and  are  based  on  historic,  current  and  future  performance  and  consider  both  quantitative  and  qualitative 
information. A long-lived asset is deemed impaired when the future expected undiscounted cash flows from its use and disposition 
is less than the assets’ carrying value. Impairment is measured based on the estimated fair value, which is usually determined based 
upon  the  present value  of  the projected  future cash  flow  compared to  the  assets’  carrying value. The  Partnership  believes its 
estimates of cash flows and discount rates are consistent with those of principal market participants. In addition to the evaluations 
discussed above, specific events such as a reduction in economically recoverable reserves or production ceasing on a property for 
an extended period may require a separate impairment evaluation be completed on a property. 

The  Partnership  evaluates  its  equity  investment  for  impairment  when  events  or  changes  in  circumstances  indicate,  in 
management’s judgment, that the carrying value of such investment may have experienced an other-than-temporary decline in 
value. When evidence of loss in value has occurred, management compares the estimated fair value of the investment to the carrying 
value of the investment to determine whether potential impairment has occurred. If the estimated fair value is less than the carrying 
value and management considers the decline in value to be other than temporary, the excess of the carrying value over the estimated 
fair value is recognized in the financial statements as an impairment loss. The fair value of the impaired investment is based on 
quoted market prices, or upon the present value of expected cash flows using discount rates believed to be consistent with those 
used by principal market participants, plus market analysis of comparable assets owned by the investee, if appropriate.

Revenue Recognition

Coal Royalty and Other Revenues.     Coal royalty and other revenues are recognized on the basis of tons of mineral mined 
or sold by the Partnership's lessees and the corresponding revenue from those sales. Generally, the lessees make payments to the 
Partnership based on the greater of a percentage of the gross sales price or a fixed price per ton of mineral they mine or sell. While 
the Partnership may have multiple contracts with a single lessee, such contracts are accounted for as separate arrangements.

Most of the Partnership’s coal and aggregates lessees must pay the Partnership minimum annual or quarterly amounts which 
are generally recoupable out of actual production over certain time periods. These minimum payments are recorded as deferred 
revenue liability when received. The deferred revenue attributable to the minimum payment is recognized as coal royalty revenue 
when the underlying mineral lease recoups the minimum payment through production or is recognized as minimums recognized 
as revenue in the period immediately following the expiration of the lessee’s ability to recoup the payments.

79

NATURAL RESOURCE PARTNERS L.P.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—CONTINUED

The Partnership periodically audits lessee information by examining certain records and internal reports of its lessees. The 
Partnership’s regional managers also perform periodic mine inspections to verify that the information that has been reported to 
the Partnership is accurate. The audit and inspection processes are designed to identify material variances from lease terms as well 
as differences between the information reported to the Partnership and the actual results from each property. Audits and inspections, 
however, are in periods subsequent to when the revenue is reported and any adjustment identified by these processes might be in 
a reporting period different from when the revenue was initially recorded. Typically there are no material adjustments from this 
process.

Oil and gas related revenues consist of revenues from royalties and overriding royalties and are recognized on the basis of 
volume of hydrocarbons sold by lessees and the corresponding revenue from those sales. Also, included within oil and gas royalties 
are lease bonus payments, which are generally paid upon the execution of a lease.

Transportation and Processing.     Transportation fees are recognized on the basis of tons of material transported over the 
beltlines. Under the terms of the transportation contracts, the Partnership receives a fixed price per ton for all material transported 
on the beltlines. Processing fees are recognized on the basis of tons of material processed through the facilities by the lessees and 
the corresponding revenue from those sales. Generally, the lessees of the processing facilities make payments to the Partnership 
based on the greater of a percentage of the gross sales price or a fixed price per ton of material that is processed and sold from the 
facilities. The  processing  leases  are  structured  in  a  manner  so  that  the  lessees  are  responsible  for  operating  and  maintenance 
expenses  associated  with  the  facilities. These  fees  are  included  in Transportation  and  processing  fees  (or Transportation  and 
processing fees-affiliate) in the Consolidated Statements of Comprehensive Income (Loss).

Equity in Earnings from Ciner Wyoming. The Partnership accounts for non-marketable equity investments using the equity 
method of accounting if the investment gives it the ability to exercise significant influence over, but not control of, an investee. 
Significant influence generally exists if the Partnership has an ownership interest representing between 20% and 50% of the voting 
stock of the investee. The Partnership accounts for its investment in Ciner Wyoming, of which it owns 49%, using this method.

Under the equity method of accounting, investments are stated at initial cost and are adjusted for subsequent additional 
investments and the proportionate share of earnings or losses and distributions. The basis difference between the investment and 
the proportional share of investee's net assets is hypothetically allocated first to identified tangible assets and liabilities, then to 
finite-lived intangibles or indefinite-lived intangibles and the balance is attributed to goodwill. The portion of the basis difference 
attributed  to  net  tangible  assets  and  finite-lived  intangibles  is  amortized  over  its  estimated  useful  life  while  indefinite-lived 
intangibles, if any, and goodwill are not amortized. The amortization of the basis difference is recorded as a reduction of earnings 
from the equity investment in the Consolidated Statements of Comprehensive Income (Loss).

The carrying value in Ciner Wyoming is reflected in the caption "Equity in unconsolidated investment" in the Partnership's 
Consolidated Balance Sheets. The Partnership's adjusted share of the earnings or losses of Ciner Wyoming is reflected in the 
Consolidated Statements of Comprehensive Income (Loss) as revenues and other income under the caption ‘‘Equity in earnings 
of Ciner Wyoming." The Partnership's share of investee earnings are adjusted to reflect the amortization of any difference between 
the cost basis of the equity investment and the proportionate share of the investee’s net assets, which has been allocated to the fair 
value of net identified tangible and finite-lived intangible assets and amortized over the estimated lives of those assets. In reporting 
cash flows of its equity method investment in Ciner Wyoming, the Partnership utilizes the cumulative earnings approach in which 
distributions received are considered returns on investment and classified as cash inflows from operating activities unless the 
cumulative distributions received exceed cumulative equity in earnings recognized by the Partnership, in which case the excess 
cumulative distributions received would be classified as cash inflows from investing activities as a return of investment. 

Construction Aggregates Revenues.     Revenues from the sale of aggregates, gravel, sand and asphalt are recorded based 

upon the transfer of product at delivery to customers, which generally occurs at the quarries or asphalt plants. 

Road Construction and Asphalt Paving.     Revenues from long-term construction contracts are recognized on the percentage-
of-completion method, measured by the percentage of total costs incurred to date to the estimated total costs for each contract. 
That  method  is  used  since  the  Partnership  considers  total  cost  to  be  the  best  available  measure  of  progress  on  the  contracts. 
Provisions for estimated losses on uncompleted contracts are made in the period in which such losses are determined. Changes in 
job performance, job conditions and estimated profitability, including those arising from final contract settlements, which result 
in revisions to job costs and profits are recognized in the period in which the revisions are determined. Contract costs include all 
direct job costs and those indirect costs related to contract performance, such as indirect labor, supplies, insurance, equipment 
maintenance and depreciation.

NATURAL RESOURCE PARTNERS L.P.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—CONTINUED

See  "—Recently  Issued Accounting  Standards  -  Revenue  Recognition"  below  for  information  regarding  the  impact  of 

adopting the new revenue recognition standard in January 2018.  

Property Taxes

The Partnership is responsible for paying property taxes on the properties it owns. Typically, the lessees are contractually 
responsible for reimbursing the Partnership for property taxes on the leased properties. The payment of and reimbursement of 
property taxes is included in Operating and maintenance expenses and in Coal Royalty and Other revenues, respectively, in the 
Consolidated Statements of Comprehensive Income (Loss).

Transportation Revenue and Expense 

The Partnership records transportation revenue and pays transportation costs to a Foresight Energy LP ("Foresight Energy") 
affiliate to operate equipment on behalf of the Partnership. The revenue and expenses related to these transactions are recorded as 
Transportation and processing revenues (or Transportation and processing revenues—affiliates) and Operating and maintenance 
expenses or (Operating and maintenance expenses—affiliates), respectively, in the Consolidated Statements of Comprehensive 
Income (Loss). Subsequent to May 9, 2017, Foresight Energy is no longer deemed a related party; refer to Note 15. Related Party 
Transactions for further details. 

Shipping and handling costs invoiced to aggregate customers and paid to third-party carriers are recorded as Construction 
Aggregates revenues and Operating and maintenance expenses in the Consolidated Statements of Comprehensive Income (Loss). 
Shipping and handling revenue included in Construction Aggregates revenues was $38.9 million, $36.0 million and $42.6 million
for the years ended December 31, 2017, 2016 and 2015, respectively. Shipping and handling costs included in Operating and 
maintenance expenses was $36.3 million, $35.9 million and $42.1 million for the years ended December 31, 2017, 2016, and 2015, 
respectively. 

Unit-Based Compensation

The Partnership has awarded unit-based compensation in the form of phantom units and accounts for such awards using the 
fair value method, which requires the Partnership to estimate compensation costs based on the fair value of the grant and remeasure 
each reporting period based on the Partnership’s common unit price over the requisite service, which is generally vesting period 
of the grant. In addition, estimated forfeitures are included in the periodic computation of the fair value of the liability. Unit-based 
compensation expense is recognized in General and administrative expense in the Consolidated Statements of Comprehensive 
Income. 

Deferred Financing Costs

Deferred financing costs consist of legal and other costs related to the issuance of the Partnership’s long-term debt. These 
costs are amortized over the term of the line-of-credit or debt arrangements. Deferred financing costs related to the Partnership's 
revolving credit facility are included in other assets (long-term) and deferred financing costs related to the Partnership's note 
agreements  are  included  as  a  direct  deduction  from  the  carrying  amount  of  the  debt  liability  in  Long-term  debt,  net  on  the 
Partnership's Consolidated Balance Sheets. 

Income Taxes

The Partnership is not subject to federal or material state income taxes, as the partners are taxed individually on their allocable 
share of taxable income. Net income for financial statement purposes may differ significantly from taxable income reportable to 
unitholders as a result of differences between the tax basis and financial reporting basis of assets and liabilities. In the event of an 
examination of the Partnership’s tax return, the tax liability of the partners could be changed if an adjustment in the Partnership’s 
income is ultimately sustained by the taxing authorities.

Recently Adopted Accounting Standards

Statement of Cash Flows. In August 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards 
Update (ASU) No. 2016-15, Statement of Cash Flows (Topic 230), which is intended to clarify how certain cash receipts and cash 
payments are presented and classified in the statement of cash flows in order to reduce current and potential future diversity in 
practice. The guidance addresses eight specific cash flow issues for which current GAAP is either unclear or does not include 
specific guidance. The guidance is effective for annual periods beginning after December 15, 2017 and interim periods within 
those annual periods. 

The  Partnership  elected  to  early  adopt  this  guidance  in  the  second  quarter  of  2017  and  elected  to  continue  to  classify 
distributions it received from its equity method investees under the cumulative earnings approach in which distributions received 
are considered returns on investment and classified as cash inflows from operating activities unless the cumulative distributions 
received exceed cumulative equity in earnings recognized by the Partnership. The early adoption of this guidance in the second 
quarter of 2017 did not have a material effect on its consolidated financial statements.

Accounting Changes and Error Corrections. In January 2017, the FASB issued ASU No. 2017-03, Accounting Changes and 
Error Corrections (Topic 250) and Investments - Equity Method and Joint Venture (Topic 323), which states that registrants should 
consider additional qualitative disclosures if the impact of an issued but not yet adopted ASU is unknown or cannot be reasonably 
estimated and to include a description of the effect of the accounting policies that the registrant expects to apply, if determined. 
Transition guidance in certain issued but not yet adopted ASUs, including Leases and Revenue Recognition, was also updated to 
reflect this amendment. This guidance is effective immediately. The Partnership adopted this guidance during the first quarter of 
2017. The adoption of this guidance impacted the Partnership's disclosures but had no effect on its financial position, results of 
operations or cash flows.

Earnings per Share. In July 2017, the FASB issued ASU No. 2017-11, Earnings Per Share (Topic 260); Distinguishing 
Liabilities from Equity (Topic 480); Derivatives and Hedging (Topic 815): (Part I) Accounting for Certain Financial Instruments 
with Down Round Features, (Part II) Replacement of the Indefinite Deferral for Mandatorily Redeemable Financial Instruments 
of Certain Nonpublic Entities and Certain Mandatorily Redeemable Noncontrolling Interests with a Scope Exception. The guidance 
eliminates the requirement to consider "down-round" features when determining whether certain equity-linked financial instruments 
or embedded features are indexed to an entity’s own stock. The guidance requires entities that present earnings per share ("EPS") 
under ASC 260 to recognize the effect of a down-round feature in a freestanding equity-classified financial instrument only when 
it is triggered. The effect of triggering such a feature will be recognized as a dividend and a reduction to income available to 
common shareholders in basic EPS. Entities will also have to make new disclosures for financial instruments with down-round 
features and other terms that change conversion or exercise prices. The guidance is effective for annual and interim periods ending 
after December 31, 2018 and early adoption is permitted. The Partnership early adopted this guidance in the third quarter of 2017. 
Refer to Note 2. Change in Method of Accounting for NRP's Warrants in the Partnerships September 30, 2017 Form 10-Q for 
disclosure of the effects of adoption on its quarterly consolidated financial statements. There was no impact to the consolidated 
financial statements for the years ended December 31, 2017, 2016 and 2015.

Recently Issued Accounting Standards

Revenue Recognition. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, as a new 
Topic, ASC Topic 606. The new revenue recognition standard provides a five-step analysis of transactions to determine when and 
how revenue is recognized. The core principle of this guidance is that an entity should recognize revenue to depict the transfer of 
promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in 
exchange for those goods or services. The guidance also requires enhanced disclosures, provide more comprehensive guidance 
for transactions such as service revenue and contract modifications, and enhance guidance for multiple-element arrangements. In 
August  2015,  the  FASB  issued ASU  No. 2015-14,  Revenue  from  Contracts  with  Customers  (Topic  606),  which  deferred  the 
effective date of ASU No. 2014-09 by one year, making the new standard effective for interim and annual periods beginning after 
December 15, 2017. This ASU can be adopted either retrospectively or as a cumulative-effect adjustment as of the date of adoption. 

Additionally, in March 2016, the FASB issued ASU No. 2016-08, Revenue from Contracts with Customers (Topic 606): 
Principal versus agent considerations (reporting revenue gross versus net), which clarifies the implementation guidance on principal 
versus agent considerations on such matters. In April 2016, the FASB issued ASU No. 2016-10, Revenue from Contracts with 
Customers  (Topic  606):  Identifying  performance  obligations  and  licensing,  which  clarifies  guidance  related  to  identifying 
performance obligations and licensing implementation guidance contained in the new revenue recognition standard. In May 2016, 

82

NATURAL RESOURCE PARTNERS L.P.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—CONTINUED

the  FASB  issued ASU  No.  2016-12,  Revenue  from  Contracts  with  Customers  (Topic  606):  Narrow-scope  improvements  and 
practical expedients, which addresses narrow-scope improvements to the guidance on collectibility, non-cash consideration, and 
completed  contracts  at  transition.  Additionally,  the  amendments  in  this  update  provide  a  practical  expedient  for  contract 
modifications at transition and an accounting policy election related to the presentation of sales taxes and other similar taxes 
collected from customers. In December 2016, the FASB issued ASU No. 2016-20, Technical Corrections and Improvements to 
Topic 606, Revenue from Contracts with Customers, which clarifies the guidance or corrects unintended application of guidance. 

The Partnership adopted the new standard on January 1, 2018 and has elected to use the modified retrospective adoption 
method. Adopting this guidance will result in increased disclosures related to revenue recognition policies and disaggregation of 
revenue. 

The Partnership identified the contracts for all of its revenue streams and utilized the practical expedient of grouping contracts 
or performance obligations with similar characteristics as prescribed by the new standard. As a result of the analysis performed, 
the Partnership concluded that the new revenue recognition standard will have no impact on revenue from NRP's Construction 
Aggregates or Soda Ash operating segments. However, the Partnership determined that adoption of the new revenue recognition 
standard will impact certain revenue from NRP's coal royalty leases as further described below. The other revenue streams within 
the Coal Royalty and Other segment will not be impacted.

Historically, NRP has recognized all coal royalty revenue over the lease term based on coal production and minimum payments 
were deferred until either recoupment occurred or the recoupment period expired. Under the new revenue recognition standard, 
management has defined NRP's coal royalty lease performance obligation as providing the lessee the right to mine and sell NRP's 
coal over the lease term.  The Partnership then evaluated the likelihood that consideration NRP received from its lessees resulting 
from  coal  production  would  exceed  consideration  received  from  minimum  payments  over  the  lease  term. As  a  result  of  this 
evaluation, revenue recognition from the Partnership's leases will now be based on either production or minimum payments as 
follows:

1.  Production Leases:  Leases for which the Partnership expects that consideration from coal production will be 
greater than consideration from minimums over the lease term.  Revenue recognition for these leases will be recognized 
over time based on coal production and minimum payments will continue to be deferred until recoupment occurs or the 
recoupment becomes remote. If the Partnership does receive minimum payments from these coal royalty leases, it will 
begin to evaluate the likelihood of recoupment and recognize deferred revenue prior to expiration of the recoupment 
period if it concludes that recoupment is remote. 

2.  Minimum Leases:  Leases for which the Partnership expects that consideration from minimums will be greater 
than consideration from coal production over the lease term. Revenue recognition for these leases will now be recognized 
straight line over the lease term based on the minimum payment consideration amount. 

As  a  result  of  implementation  of  the  new  standard  for  the  Partnership's  coal  lease  contracts,  NRP  expects  to  record 
approximately $80 million to $90 million reduction to deferred revenue and a corresponding increase in retained earnings on 
January 1, 2018. The Partnership will perform this contract evaluation at the end of each reporting period going forward.

Leases. In  February 2016,  the FASB issued ASU No. 2016-02,  Leases, as  a new Topic, ASC Topic 842. The new  lease 
guidance supersedes Topic 840. Lessees are to recognize assets and liabilities on the balance sheet for the present value of the 
rights and obligations created by all leases with terms of more than 12 months. This ASU does not apply to leases to explore for 
or use minerals, oil, natural gas and similar non-regenerative resources, including the intangible right to explore for those natural 
resources and rights to use the land in which those natural resources are contained. The guidance also requires disclosures designed 
to give financial statement users information on the amount, timing, and uncertainty of cash flows arising from leases. The guidance 
is effective for annual and interim periods beginning after December 31, 2018. The Partnership is currently evaluating the impact 
of the provisions of this guidance on its consolidated financial statements.

3.    Class A Convertible Preferred Units and Warrants

On March 2, 2017, NRP issued $250 million of Class A Convertible Preferred Units representing limited partner interests in 
NRP (the "Preferred Units") to certain entities controlled by funds affiliated with The Blackstone Group, L.P. (collectively referred 
to as "Blackstone") and certain affiliates of GoldenTree Asset Management LP (collectively referred to as "GoldenTree") (together 
the "Preferred Purchasers") pursuant to a Preferred Unit and Warrant Purchase Agreement. NRP issued 250,000 Preferred Units 
to the Preferred Purchasers at a price of $1,000 per Preferred Unit (the "Per Unit Purchase Price"), less a 2.5% structuring and 
origination fee. The Preferred Units entitle the Preferred Purchasers to receive cumulative distributions at a rate of 12% per year, 
up to one half of which NRP may pay in additional Preferred Units (such additional Preferred Units, the "PIK Units"). The Preferred 
Units have a perpetual term, unless converted or redeemed as described below.

NRP also issued two tranches of warrants (the "Warrants") to purchase common units to the Preferred Purchasers (Warrants 
to purchase 1.75 million common units with a strike price of $22.81 and Warrants to purchase 2.25 million common units with a 
strike price of $34.00). The Warrants may be exercised by the holders thereof at any time before the eighth anniversary of the 
closing date. Upon exercise of the Warrants, NRP may, at its option, elect to settle the Warrants in common units or cash, each on 
a net basis.  

After March 2, 2022 and prior to March 2, 2025, the holders of the Preferred Units may elect to convert up to 33% of the 
outstanding Preferred Units in any 12-month period into common units if the volume weighted average trading price of our common 
units (the "VWAP") for the 30 trading days immediately prior to date notice is provided is greater than $51.00. In such case, the 
number of common units to be issued upon conversion would be equal to the Per Unit Purchase Price plus the value of any accrued 
and unpaid distributions divided by an amount equal to a 7.5% discount to the VWAP for the 30 trading days immediately prior 
to the notice of conversion. Rather than have the Preferred Units convert to common units in accordance with the provisions of 
this paragraph, NRP would have the option to elect to redeem the Preferred Units proposed to be converted for cash at a price 
equal to Per Unit Purchase Price plus the value of any accrued and unpaid distributions. 

On or after March 2, 2025, the holders of the Preferred Units may elect to convert the Preferred Units to common units at a 
conversion rate equal to the Liquidation Value divided by an amount equal to a 10% discount to the VWAP for the 30 trading days 
immediately prior to the notice of conversion.  The “Liquidation Value” will be an amount equal to the greater of: (1) (a) the Per 
Unit Purchase Price multiplied by (i) prior to March 2, 2020, 1.50, (ii) on or after March 2, 2020 and prior to March 2, 2021, 1.70
and (iii) on or after March 2, 2021, 1.85, less (b)(i) all Preferred Unit distributions previously made by NRP and (ii) all cash 
payments previously made in respect of redemption of any PIK Units; and (2) the Per Unit Purchase Price plus the value of all 
accrued and unpaid distributions.  

To the extent the holders of the Preferred Units have not elected to convert their Preferred Units before March 2, 2029, NRP 
has the right to force conversion of the Preferred Units at a price equal to the Liquidation Value divided by an amount equal to a 
10% discount to the VWAP for the 30 trading days immediately prior to the notice of conversion. 

In addition, NRP has the ability to redeem at any time (subject to compliance with its debt agreements) all or any portion of 
the Preferred Units and any outstanding PIK Units for cash. The redemption price for each outstanding PIK Unit is $1,000 plus 
the value of any accrued and unpaid distributions per PIK Unit. The redemption price for each Preferred Unit is the Liquidation 
Value divided by the number of outstanding Preferred Units. The Preferred Units are redeemable at the option of the Preferred 
Purchasers only upon a change in control. 

The terms of the Preferred Units contain certain restrictions on NRP's ability to pay distributions on its common units. To 
the extent that either (i) NRP's consolidated Leverage Ratio, as defined in the Partnership's Fifth Amended and Restated Partnership 
Agreement dated March 2, 2017 (the "Restated Partnership Agreement"), is greater than 3.25x, or (ii) the ratio of NRP's Distributable 
Cash Flow (as defined in the Restated Partnership Agreement) to cash distributions made or proposed to be made is less than 1.2x 
(in each case, with respect to the most recently completed four-quarter period), NRP may not increase the quarterly distribution 
above $0.45 per quarter without the approval of the holders of a majority of the outstanding Preferred Units. In addition, if at any 
time after January 1, 2022, any PIK Units are outstanding, NRP may not make distributions on its common units until it has 
redeemed all PIK Units for cash. 

The holders of the Preferred Units have the right to vote with holders of NRP’s common units on an as-converted basis and 
have other customary approval rights with respect to changes of the terms of the Preferred Units. In addition, Blackstone has certain 
approval rights over certain matters as identified in the Restated Partnership Agreement. GoldenTree also has more limited approval 

84

NATURAL RESOURCE PARTNERS L.P.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—CONTINUED

rights that will expand once Blackstone's ownership goes below the Minimum Preferred Unit Threshold (as defined below). These 
approval rights are not transferrable without NRP's consent. In addition, the approval rights held by Blackstone and GoldenTree 
will terminate at such time that Blackstone (together with their affiliates) or GoldenTree (together with their affiliates), as applicable, 
no longer own at least 20% of the total number of Preferred Units issued on the closing date, together with all PIK Units that have 
been issued but not redeemed (the "Minimum Preferred Unit Threshold").

At the closing, pursuant to the Board Representation and Observation Rights Agreement, the Preferred Purchasers received 
certain board appointment and observation rights, and Blackstone appointed one director and one observer to the Board of Directors 
of GP Natural Resource Partners LLC. 

NRP also entered into a registration rights agreement (the "Preferred Unit and Warrant Registration Rights Agreement") with 
the Preferred Purchasers, pursuant to which NRP is required to file (i) a shelf registration statement to register the common units 
issuable upon exercise of the Warrants and to cause such registration statement to become effective not later than 90 days following 
the closing date and (ii) a shelf registration statement to register the common units issuable upon conversion of the Preferred Units 
and to cause such registration statement to become effective not later than the earlier of the fifth anniversary of the closing date 
or 90 days following the first issuance of any common units upon conversion of Preferred Units (the "Registration Deadlines"). 
In addition, the Preferred Unit and Warrant Registration Rights Agreement gives the Preferred Purchasers piggyback registration 
and demand underwritten offering rights under certain circumstances. The shelf registration statement to register the common units 
issuable upon exercise of the Warrants became effective on April 20, 2017. If the shelf registration statement to register the common 
units issuable upon conversion of the Preferred Units is not effective by the applicable Registration Deadline, NRP will be required 
to pay the Preferred Purchasers liquidated damages in the amounts and upon the term set forth in the Preferred Unit and Warrant 
Registration Rights Agreement.

Accounting for the Preferred Units and Warrants

Classification

The Preferred Units are accounted for on NRP's consolidated balance sheets as temporary equity due to certain contingent 
redemption  rights  that  may  be  exercised  at  the  election  of  Preferred  Purchasers.  The  Warrants  are  accounted  for  on  NRP's 
consolidated balance sheets as equity. Prior to July 1, 2017, the Warrants were previously classified as a liability because of a 
"down-round" anti-dilution price protection provision that would reduce the Warrant holders' exercise price if NRP were to sell 
common units at a price less than the current strike price (subject to certain exceptions). The Partnership retrospectively adopted 
ASU No. 2017-11, Earnings Per Share (Topic 260) in the third quarter of 2017 and reclassified the Warrants on its Consolidated 
Balance Sheets. Refer to Note 2. Summary of Significant Accounting Policies for more discussion.

Initial Measurement

The net transaction price as shown below was allocated to the Preferred Units and Warrants based on their relative fair values 
at inception date. NRP allocated the transaction issuance costs to the Preferred Units and Warrants primarily on a pro-rata basis 
based on their relative inception date allocated values. The Preferred Units and Warrants were initially recognized as follows:

(In thousands)
Transaction price, gross

Structuring, origination and other fees to Preferred Purchasers

Transaction costs to other third parties

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—CONTINUED

Subsequent Measurement

Subsequent adjustment of the Preferred Units will not occur until NRP has determined that the conversion or redemption of 
all or a portion of the Preferred Units is probable of occurring. Once conversion or redemption becomes probable of occurring, 
the carrying amount of the Preferred Units will be accreted to their redemption value over the period from the date the feature is 
probable of occurring to the date the Preferred Units can first be converted or redeemed.

Subsequent adjustment of the Warrants will not occur until the Warrants are exercised, at which time, NRP may, at its option, 
elect to settle the Warrants in common units or cash, each on a net basis. The net basis will be equal to the difference between the 
Partnership's common unit price and the strike price of the Warrant. Once Warrant exercise occurs, the difference between the 
carrying amount of the Warrants and the net settlement amount will be allocated on a pro-rata basis to the common unitholders 
and general partner.

Certain embedded features within the Preferred Unit and Warrant purchase agreement are accounted for at fair value and are 
remeasured each quarter. See Note 14. Fair Value Measurements for further information regarding valuation of these embedded 
derivatives.  

4.    Common and Preferred Unit Distributions

The Partnership makes cash distributions to common unit holders on a quarterly basis, subject to approval by the Board of 
Directors. The Partnership also makes distributions to the preferred unitholders at a rate of 12% per year, up to one half of which 
NRP may pay in additional Preferred Units (such additional Preferred Units, the "PIK Units"), subject to approval by the Board 
of Directors. NRP recognizes both Common and Preferred Unit distributions on the date the distribution is declared. 

Common Unit Distributions

Distributions made on the common units and the general partner's general partner interest are made on a pro-rata basis in 
accordance  with  their  relative  percentage  interests  in  the  Partnership.  The  general  partner  is  entitled  to  receive  2%  of  such 
distributions. The following table shows the distributions paid by the Partnership on its common units and general partner's general 
partner interest during the years ended December 31, 2017, 2016 and 2015:

Income available to common unitholders and the general partner is reduced by Preferred Unit distributions that accumulated 
during the period. During the year ended December 31, 2017, NRP reduced net income attributable to common unitholders and 
the general partner by $25.5 million as a result of accumulated Preferred Unit distributions. 

Subsequent Event

On February 14, 2018, the Partnership paid a distribution of $0.45 per unit to unitholders of record on February 7, 2018. In 
addition, the Partnership paid a distribution on NRP's 12.0% Class A Convertible Preferred Units with respect to the fourth quarter. 
The entire $7.8 million distribution on the Preferred Units was paid in cash. Additionally, the Partnership redeemed all of the 
outstanding PIK Units, which resulted in an $8.8 million cash payment.

5.    Net Income Per Common Unit 

Basic net income per common unit is computed by dividing net income, after considering income attributable to preferred 
unitholders and the general partner’s interest, by the weighted average number of common units outstanding. Diluted net income 
per common unit includes the effect of NRP's Warrants and Preferred Units (see Note 3. Class A Convertible Preferred Units and 
Warrants), if the inclusion of these items is dilutive. 

The dilutive effect of the Warrants is calculated using the treasury stock method, which assumes that the proceeds from the 
exercise of these instruments are used to purchase common units at the average market price for the period. The calculation of the 
dilutive effect of the Warrants for the three and twelve months ended December 31, 2017, did not include the net settlement of 
Warrants to purchase 2.25 million common units with a strike price of $34.00 because the impact would have been anti-dilutive. 

The dilutive effect of the Preferred Units is calculated using the if-converted method. Under the if-converted method, the 
Preferred Units are assumed to be converted at the beginning of the period, and the resulting common units are included in the 
denominator of the diluted net income per unit calculation for the period being presented. Interest recognized during the period 
(including the effect of accretion of discounts and amortization of issuance costs, if any), distributions declared in the period and 
undeclared distributions on the Preferred Units that accumulated during the period are added back to the numerator for purposes 
of the if-converted calculation.

6.    Segment Information

The Partnership's segments are strategic business units that offer products and services to different customers in different 

geographies within the U.S. and that are managed accordingly. NRP has the following three operating segments: 

Coal Royalty and Other—consists primarily of coal royalty and coal-related transportation and processing assets. Other 
assets include aggregates royalty, industrial mineral royalty, oil and gas royalty and timber. The Partnership's coal reserves are 
primarily located in Appalachia, the Illinois Basin and the Western United States. The Partnership's aggregates and industrial 
minerals properties are located in a number of states across the United States. The Partnership's oil and gas royalty assets are 
primarily located in Louisiana.  

Soda Ash—consists of the Partnership's 49% non-controlling equity interest in a trona ore mining operation and soda ash 
refinery in the Green River Basin, Wyoming. Ciner Resources LP, the Partnership's operating partner, mines the trona, processes 
it into soda ash, and distributes the soda ash both domestically and internationally into the glass and chemicals industries. The 
Partnership receives regular quarterly distributions from this business. 

Construction Aggregates—consists of the Partnership's construction materials business that operates hard rock quarries, 
an underground limestone mine, sand and gravel plants, asphalt plants and marine terminals. Construction Aggregates operates in 
Pennsylvania, West Virginia, Tennessee, Kentucky and Louisiana.

Direct segment costs and certain costs incurred at the corporate level that are identifiable and that benefit the Partnership's 
segments are allocated to the operating segments. These allocated costs include costs of: taxes, legal, information technology and 
shared facilities services and are included in Operating and maintenance expenses and Operating and maintenance expenses—
affiliates on the Consolidated Statements of Comprehensive Income (Loss). Intersegment sales are at prices that approximate 
market.

Corporate  and  Financing includes  functional  corporate  departments  that  do  not  earn  revenues.  Costs  incurred  by  these 
departments include interest and financing, corporate headquarters and overhead, centralized treasury and accounting and other 
corporate-level activity not specifically allocated to a segment and are included in General and administrative expenses and General

7.    Discontinued Operations

In July 2016, NRP Oil and Gas sold its non-operated oil and gas working interest assets for $116.1 million in gross sales 

proceeds. The sale had an effective date of April 1, 2016.

The Partnership's exit from its non-operated oil and gas working interest business represented a strategic shift to reduce debt 
and focus on its coal royalty, soda ash and construction aggregates business segments. As a result, the Partnership classified the 
operating results, cash flows and assets and liabilities of its non-operated oil and gas working interest assets as discontinued 
operations in its Consolidated Balance Sheets, Consolidated Statements of Comprehensive Income and Consolidated Statements 
of Cash Flows for all periods presented. The Partnership transitioned the remaining investments in royalty interests in oil and 
natural gas properties into the Coal Royalty and Other operating segment during the third quarter of 2016.

Asset Divestitures 

During the year ended December 31, 2017, the Partnership sold mineral reserves in its Coal Royalty and Other segment in 
multiple transactions for cumulative $1.0 million of gross sales proceeds and recorded a $3.5 million gain on asset sales included 
in Gain on asset sales, net on its Consolidated Statement of Comprehensive Income (Loss). 

During the year ended December 31, 2016, the Partnership completed the sale of the following assets:

1)  Oil and gas royalty and overriding royalty interests in the Coal Royalty and Other segment in several producing properties 
located in the Appalachian Basin for $36.4 million gross sales proceeds. The effective date of the sale was January 1, 2016, and 
the Partnership recorded an $18.6 million gain from this sale included in Gain on asset sales, net on its Consolidated Statement of 
Comprehensive Income (Loss).

2)  Aggregates reserves and related royalty rights in the Coal Royalty and Other segment at three aggregates operations 
located in Texas, Georgia and Tennessee for $10.0 million gross sales proceeds. The effective date of the sale was February 1, 
2016, and the Partnership recorded a $1.5 million gain from this sale included in Gain on asset sales, net on its Consolidated 
Statement of Comprehensive Income (Loss).

In addition to the two asset sales described above, during the year ended December 31, 2016, the Partnership sold mineral 
reserves  within  its  Coal  Royalty  and  Other  segment  in  multiple  sale  transactions  for  cumulative  $17.3  million  of  gross  sales 
proceeds and recorded $8.6 million of cumulative gain from these sale transactions that are included in Gain on asset sales, net 
on its Consolidated Statement of Comprehensive Income (Loss). These amounts primarily relate to eminent domain transactions 
with governmental agencies and the sale of additional oil and gas royalty interests.

During the year ended December 31, 2015, the Partnership sold mineral reserves in its Coal Royalty and Other segment in 
multiple transactions for cumulative $3.5 million of gross sales proceeds and recorded a $3.3 million gain on asset sales included 
in Gain on asset sales, net on its Consolidated Statement of Comprehensive Income (Loss). 

Impairment of Mineral Rights 

For the evaluation of the Partnership's long-lived assets for possible impairment, inputs used by management for fair value 
measurements include significant inputs that are not observable in the market and thus represent a Level 3 fair value measurement 
for  these  types  of  assets.  In  addition  to  the  evaluations  discussed  above,  specific  events  such  as  a  reduction  in  economically 
recoverable reserves or production ceasing on a property for an extended period may require that a separate impairment evaluation 
be completed on a significant property.

(1)  The  Partnership  recorded  $0.6  million  of  coal  property  impairments  during  the  year  ended  December 31,  2017.  The 
Partnership recorded $12.1 million of coal property impairments during the year ended December 31, 2016, primarily as 
a result of lease surrender and termination. The Partnership recorded $3.8 million of coal property impairment during the 
three months ended September 30, 2016 and the fair value of the impaired asset was reduced to $4.0 million at September 
30, 2016. The Partnership recorded $8.2 million of coal property impairment during the three months ended December 31, 
2016 and the fair value of the impaired asset was reduced to $0.0 million at December 31, 2016. Total coal property 
impairment expense for the year ended December 31, 2015 was $257.5 million. The Partnership recorded $1.5 million of 
coal property impairment during the three months ended June 30, 2015 and the fair value measurement of these impaired 
assets was reduced to $0.0 million at June 30, 2015. The Partnership recorded $247.8 million of coal property impairment 
during the three months ended September 30, 2015 and the fair value of these impaired assets was reduced to $28.4 million 
at September 30, 2015. The Partnership recorded the remaining $8.2 million of coal property impairment during the three 
months ended December 31, 2015 and the fair value of these impaired assets was reduced to $0.4 million at December 31, 
2015. These impairments primarily resulted from the continued deterioration and expectations of further reductions in 
global and domestic coal demand due to reduced global steel demand, sustained low natural gas prices, and continued 
regulatory pressure on the electric power generation industry. NRP compared net capitalized costs of its coal properties to 
estimated undiscounted future net cash flows. If the net capitalized cost exceeded the undiscounted future cash flows, the 
Partnership recorded an impairment for the excess of net capitalized cost over fair value. Significant inputs used to determine 
fair value include estimates of future cash flow, discount rate and useful economic life. Estimated cash flows are the product 
of a process that began with current realized pricing as of the measurement date and included an adjustment for risk related 
to the future realization of cash flows. 

(2)  The Partnership recorded $36 thousand of oil and gas royalty asset impairment during the year ended December 31, 2016. 
The total oil and gas royalty impairment for the year ended December 31, 2015 was $70.5 million. The Partnership recorded 
this impairment during the three months ended September 30, 2015. The fair value measurement of these impaired assets 
was reduced to $13.0 million at September 30, 2015. This impairment primarily resulted from declines in future expected 
realized commodity prices and reduced expected drilling activity on its acreage. NRP compared net capitalized costs of 
its oil and gas royalty properties to estimated undiscounted future net cash flows. If the net capitalized cost exceeded the 
undiscounted future net cash flows, the Partnership recorded an impairment for the excess of net capitalized cost over fair 
value. A discounted cash flow method was used to estimate fair value. Significant inputs used to determine the fair value 
include estimates of: (i) oil and gas reserves and risk-adjusted probable and possible reserves; (ii) future commodity prices; 
(iii) production costs, (iv) capital expenditures, (v) production and (vi) discount rates. The underlying commodity prices 
embedded in the Partnership's estimated cash flows are the product of a process that begins with NYMEX forward curve 
pricing as of the measurement date, adjusted for estimated location and quality differentials.

(3)  The  Partnership  recorded  $2.4  million  of  aggregates  and  timber  royalty  property  impairments  during  the  year  ended 
December 31, 2017. The Partnership recorded $1.7 million of aggregates royalty property impairments during the year 
ended December 31, 2016. Total aggregates property impairment expense for the year ended December 31, 2015 was $43.4 
million. This impairment was recorded during the three months ended September 30, 2015. The fair value measurement 
of these impaired assets was reduced to $13.1 million at September 30, 2015. This impairment primarily resulted from 
greenfield development projects that have not performed as projected, leading to recent lease concessions on minimums 
and royalties combined with the continued regional market decline for certain properties. NRP compared net capitalized 
costs of its aggregates properties to estimated undiscounted future net cash flows. If the net capitalized cost exceeded the 
undiscounted cash flows, the Partnership recorded an impairment for the excess of net capitalized cost over fair value. A 
discounted cash flow model was used to estimate fair value. Significant inputs used to determine fair value include estimates

of future cash flow, discount rate and useful economic life. Estimated cash flows are the product of a process that began 
with current realized pricing as of the measurement date and included an adjustment for risk related to the future realization 
of cash flows.

12.    Goodwill and Intangible Assets (Including Affiliate)

The Partnership's intangible assets (including affiliate) primarily consists of above market coal transportation contracts with 
subsidiaries of Foresight Energy in which the Partnership receives throughput fees for the handling and transportation of coal. As 
of May 9, 2017, Foresight Energy is no longer deemed to be an affiliate of the Partnership. Refer to Note 15. Related Party 
Transactions for additional details. The Partnership's intangible assets include permits, aggregates-related trade names and other 
agreements. The Partnership's intangible assets (including affiliate) included in the Partnership's Consolidated Balance Sheets are

The weighted average remaining amortization period for contract intangibles and other intangibles was 25 years and 14 

years, respectively. 

During  2014,  $52.0  million  of  goodwill  was  added  relating  to  the  Construction Aggregates  acquisition.  This  amount 
represented the preliminary residual value. During 2015, the purchase price allocation was adjusted as more detailed analysis was 
completed and additional information was obtained about the facts and circumstances for Construction Aggregates’ property, plant 
and equipment, right to mine assets and asset retirement obligations that existed as of the acquisition date. These adjustments 
decreased goodwill by $46.5 million and resulted in an acquisition date goodwill of $5.5 million. During 2015, the Partnership 
evaluated goodwill for impairment and compared the estimated fair value of the Construction Aggregates reporting unit to its 
carrying  amount. The  carrying  amount  exceeded  fair  value and  the  Partnership  recorded a  $5.5  million  goodwill  impairment 
expense include in Asset impairments on the Partnership's Consolidated Statements of Comprehensive Income (Loss). The lower 
fair value was primarily a result of the deterioration in certain regional markets in which Construction Aggregates operates causing 
a decline in future performance levels compared to levels estimated during the purchase price allocation process. A discounted 
cash flow model was used to estimate fair value. Significant inputs used to determine fair value include estimates of future cash 
flow, discount rate and useful economic life. These estimates were based on current conditions and historical experience applied 
to develop projections of future operating performance.

NRP LP Debt

NRP 2018 Senior Notes    

In March 2017, the Partnership and NRP Finance exchanged $241 million aggregate principal amount of the 2018 Senior 
Notes for $241 million aggregate principal amount of a new series of 10.500% Senior Notes due 2022 (the “2022 Senior Notes”). 
In April 2017, the Partnership and NRP Finance redeemed $90 million in aggregate principal amount of the 2018 Senior Notes at 
a redemption price of 104.563%, and paid all accrued and unpaid interest thereon. In addition, pursuant to the 2022 Indenture (as 
defined below), the Partnership and NRP Finance redeemed the remaining outstanding $94.4 million of 2018 Senior Notes at par 
(and paid accrued and unpaid interest thereon) on October 2, 2017 using a combination of cash on hand and borrowings from the 
Opco Credit Facility.

2022 Senior Notes

In March 2017, NRP and NRP Finance issued $346 million aggregate principal amount of 2022 Senior Notes to several 
holders of their 2018 Senior Notes. Of the $346 million of 2022 Senior Notes issued, $241 million in aggregate principal amount 
were issued in exchange for $241 million in aggregate principal amount of 2018 Senior Notes, and $105 million of the 2022 Senior 
Notes were issued to the holders for cash. The 2022 Senior Notes are issued under an Indenture dated as of March 2, 2017 (the 
"2022  Indenture"),  bear  interest  at  10.500%  per  year,  are  payable  semi-annually  on  March  15  and  September  15,  beginning 
September 15, 2017, and mature on March 15, 2022. The $105.0 million in 2022 Senior Notes purchased for cash were issued at 
a price of 98.75% (original issue discount of 1.25%), and each holder exchanging 2018 Senior Notes received a fee of 5.813% of 
the aggregate principal amount of all 2018 Senior Notes tendered for exchange by such holder, as well as all accrued and unpaid 
interest thereon. The 5.813% fee included a 4.563% call premium on the early repayment of the 2018 Senior Notes and a 1.25%
fee on the exchange of the 2018 Notes for 2022 Senior Notes. This fee is accounted for as a debt issue cost, capitalized and shown 
net of the debt liability on our consolidated balance sheets.

NRP and NRP Finance have the option to redeem the 2022 Senior Notes, in whole or in part, at any time on or after March 
15, 2019, at the redemption prices (expressed as percentages of principal amount) of 105.25% for the 12-month period beginning 
March 15, 2019, 102.625% for the 12-month period beginning March 15, 2020, and thereafter at 100.000%, together, in each case, 
with any accrued and unpaid interest to the date of redemption. Furthermore, before March 15, 2019, NRP may on any one or 
more occasions redeem up to 35% of the aggregate principal amount of the 2022 Senior Notes with the net proceeds of certain 
public or private equity offerings at a redemption price of 110.500% of the principal amount of 2022 Senior Notes, plus any accrued 
and unpaid interest, if any, to the date of redemption, if at least 65% of the aggregate principal amount of the 2022 Senior Notes 
issued under the 2022 Indenture remains outstanding immediately after such redemption and the redemption occurs within 180 
days of the closing date of such equity offering. In the event of a change of control, as defined in the 2022 Indenture, the holders 
of the 2022 Senior Notes may require the Partnership to purchase their 2022 Senior Notes at a purchase price equal to 101% of 
the principal amount of the 2022 Senior Notes, plus accrued and unpaid interest, if any. 

The 2022 Indenture contains restrictive covenants that are substantially similar to those contained in the Indenture governing 
the 2018 Senior Notes, except that the debt incurrence and restricted payments covenants contain additional restrictions. Under 
the debt incurrence covenant, NRP's non-guarantor restricted subsidiaries will not be permitted to incur additional indebtedness 
unless their consolidated leverage ratio is less than 3.00x (measured on a pro forma basis and assuming that the greater of (i) $150.0 
million of debt (or, if less, at NRP's election, the amount of total lending commitments under any revolving credit facility) and (ii) 
the actual amount of debt outstanding is outstanding under any revolving credit facility); provided, however, that such non-guarantor 
restricted subsidiaries will be permitted to make up to $150 million in borrowings under a revolving credit facility (which amount 
will be reduced on a dollar-for-dollar basis to the extent NRP has made the election described in clause (i) above). Under the 
restricted payments covenant, NRP will not be able to increase the quarterly distribution on its common units or elect to pay more 
than 50% of the distributions required to be made on the Preferred Units in cash, unless, in each case, its consolidated leverage 
ratio is less than 4.00x. The 2022 Indenture also contains restrictions on NRP's ability to redeem the Preferred Units.

The 2022 Senior Notes are the senior unsecured obligations of NRP and NRP Finance. The 2022 Senior Notes rank equal 
in right of payment to all existing and future senior unsecured debt of NRP and NRP Finance and senior in right of payment to 
any of NRP's subordinated debt. The 2022 Senior Notes are effectively subordinated in right of payment to all future secured debt 
of NRP and NRP Finance to the extent of the value of the collateral securing such indebtedness and are structurally subordinated 
in right of payment to all existing and future debt and other liabilities of our subsidiaries, including the Opco Credit Facility and 
each series of Opco’s existing senior notes. None of NRP's subsidiaries guarantee the 2022 Senior Notes.

NATURAL RESOURCE PARTNERS L.P.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—CONTINUED

As of December 31, 2017 and December 31, 2016, NRP and NRP Finance were in compliance with the terms of its debt 

agreements.

Opco Debt

All of Opco’s debt is guaranteed by its wholly owned subsidiaries and is secured by certain of the assets of Opco and its 
wholly owned subsidiaries other than NRP Trona LLC, as further described below. As of December 31, 2017 and 2016, Opco was 
in compliance with the terms of the financial covenants contained in its debt agreements.

Opco Credit Facility

Opco’s Third Amended and Restated Credit Agreement, as amended (the "Opco Credit Facility"), matures on April 30, 2020. 
Commitments under the Opco Credit Facility were reduced to $150 million at December 31, 2017 and will be further reduced to 
$100 million at December 31, 2018 through maturity in April 2020. 

Indebtedness under the Opco Credit Facility bears interest, at Opco's option, at:

• 

the higher of (i) the prime rate as announced by the agent bank; (ii) the federal funds rate plus 0.50%; or (iii) LIBOR 
plus 1%, in each case plus an applicable margin ranging from 2.50% to 3.50%; or

• 

a rate equal to LIBOR plus an applicable margin ranging from 3.50% to 4.50%.

The  weighted  average  interest  rates  for  the  borrowings  outstanding  under  the  Opco  Credit  Facility  for  the  years  ended 
December 31, 2017 and 2016 were 5.32% and 4.46%, respectively. Debt issue cost related to the OpCo credit facility were $4.6 
million and $4.0 million at December 31, 2017 and December 31, 2016, respectively and have been capitalized and included in 
Other assets on the Partnership's Consolidated Balance Sheets. Opco will incur a commitment fee on the unused portion of the 
revolving credit facility at a rate of 0.50% per annum. Opco may prepay all amounts outstanding under the Opco Credit Facility 
at any time without penalty. As of December 31, 2017, Opco had $60.0 million of indebtedness outstanding and $90.0 million in 
borrowing capacity under our Opco Credit Facility.

The Opco Credit Facility contains financial covenants requiring Opco to maintain:

• 

• 

a leverage ratio of consolidated indebtedness to EBITDDA (as defined in the Opco Credit Facility) not to exceed 4.0x; 
provided, however, that if NRP increases its quarterly distribution to its common unitholders above $0.45 per common 
unit, the maximum leverage ratio under the Opco Credit Facility will permanently decrease from 4.0x to 3.0x; and 

a fixed charge coverage ratio of consolidated EBITDDA to consolidated fixed charges (consisting of consolidated interest 
expense and consolidated lease expense) of not less than 3.5 to 1.0. 

The Opco Credit Facility contains certain additional customary negative covenants that, among other items, restrict Opco’s 
ability to incur additional debt, grant liens on its assets, make investments, sell assets and engage in business combinations. Included 
in the investment covenant are restrictions upon Opco’s ability to acquire assets where Opco does not maintain certain levels of 
liquidity. In addition, Opco is required to use 75% of the net cash proceeds of certain non-ordinary course asset sales to repay the 
Opco Credit Facility (without any corresponding commitment reduction) and use the remaining 25% of the net cash proceeds to 
offer to repay its senior notes on a pro-rata basis, as described below under “—Opco Senior Notes.” The Opco Credit Facility also 
contains customary events of default, including cross-defaults under Opco’s senior notes.

The Opco Credit Facility is collateralized and secured by liens on certain of Opco’s assets with carrying values of $649.7 
million and $673.0 million classified as Land, Plant and equipment and Mineral rights on the Partnership’s Consolidated Balance 
Sheets as of December 31, 2017 and 2016, respectively. The collateral includes (1) the equity interests in all of Opco’s wholly 
owned subsidiaries, other than NRP Trona LLC (which owns a 49% non-controlling equity interest in Ciner Wyoming), (2) the 
personal property and fixtures owned by Opco’s wholly owned subsidiaries, other than NRP Trona LLC, (3) Opco’s material coal 
royalty revenue producing properties, (4) real property associated with certain of Construction Aggregates’ construction aggregates 
mining operations, and (5) certain of Opco’s coal-related infrastructure assets.

Opco Senior Notes   

Opco has issued several series of private placement senior notes (the "Opco Senior Notes") with various interest rates and 
principal due dates. As of December 31, 2017 and 2016, the Opco Senior Notes had cumulative principal balances of $422.2 
million and $503.0 million, respectively. Opco made mandatory principal payments on the Opco Senior Notes of $80.8 million
$82.9 million and $80.8 million for the years ended December 31, 2017, 2016 and 2015, respectively. 

The Note Purchase Agreements relating to the Opco Senior Notes contain covenants requiring Opco to: 

•  maintain a ratio of consolidated indebtedness to consolidated EBITDDA (as defined in the note purchase agreement) of 

no more than 4.0 to 1.0 for the four most recent quarters;

• 

not permit debt secured by certain liens and debt of subsidiaries to exceed 10% of consolidated net tangible assets (as 
defined in the note purchase agreement); and

•  maintain the ratio of consolidated EBITDDA (as defined in the note purchase agreement) to consolidated fixed charges 
(consisting of consolidated interest expense and consolidated operating lease expense) at not less than 3.5 to 1.0.

In addition, the Note Purchase Agreements include a covenant that provides that, in the event NRP Operating or any of its 
subsidiaries is subject to any additional or more restrictive covenants under the agreements governing its material indebtedness 
(including the Opco Credit Facility and all renewals, amendments or restatements thereof), such covenants shall be deemed to be 
incorporated by reference in the Note Purchase Agreements and the holders of the Notes shall receive the benefit of such additional 
or more restrictive covenants to the same extent as the lenders under such material indebtedness agreement.

The 8.38% and 8.92% Opco Senior Notes also provide that in the event that Opco’s leverage ratio of consolidated indebtedness 
to consolidated EBITDDA (as defined in the Note Purchase Agreements) exceeds 3.75 to 1.00 at the end of any fiscal quarter, then 
in addition to all other interest accruing on these notes, additional interest in the amount of 2.00% per annum shall accrue on the 
notes for the two succeeding quarters and for as long thereafter as the leverage ratio remains above 3.75 to 1.00. Opco has not 
exceeded the 3.75 to 1.00 ratio at the end of any fiscal quarter through December 31, 2017. 

In September 2016, Opco amended the Opco Senior Notes. Under this amendment, Opco agreed to use certain asset sale 

proceeds to make mandatory prepayment offers on the Opco Senior Notes as follows:

• 

• 

until the earlier of the time that (1) Opco has sold $300 million of assets and (2) June 30, 2020, Opco will be required 
to make prepayment offers to the holders of the Opco Senior Notes using 25% of the net cash proceeds from certain 
asset sales; and

after the earlier to occur of the dates above, Opco will be required to make prepayment offers to the holders of the Opco 
Senior Notes using an amount of net cash proceeds from certain asset sales that will be calculated pro-rata based on the 
amount of Opco Senior Notes then outstanding compared to the other total Opco senior debt outstanding that is being 
prepaid.  

The mandatory prepayment offers described above will be made pro-rata across each series of outstanding Opco Senior 
Notes and will not require any make-whole payment by Opco. In addition, the remaining principal and interest payments on the 
Opco Senior Notes will be adjusted accordingly based on the amount of Opco Senior Notes actually prepaid. The prepayments do 
not affect the maturity dates of any series of the Opco Senior Notes.

14.    Fair Value Measurements 

Fair Value of Financial Instruments

The  Partnership’s  financial  instruments  consist  of  cash  and  cash  equivalents,  accounts  receivable,  contracts  receivable, 
accounts payable, debt, Preferred Units and warrants. The carrying amounts reported on the Consolidated Balance Sheets for cash 
and cash equivalents, accounts receivable and accounts payable approximate fair value due to their short-term nature. There were 
no transfers between Level 1, Level 2 or Level 3 of the fair value hierarchy during the years ended December 31, 2017 or 2016.

The Partnership uses available market data and valuation methodologies to estimate the fair value of debt. The fair value of 
debt is the estimated amount the Partnership would have to pay a third party to assume the debt, including a credit spread for the 
difference between the issue rate and the period end market rate. The credit spread is the Partnership's default or repayment risk. 
The following table shows the carrying amount and estimated fair value of the Partnership's debt and contracts receivable (including 
affiliates):

(1)  The Level 1 fair value is based upon quotations obtained for identical instruments on the closing trading prices near period 

end.

(2)  Due to no observable quoted prices on these instruments, the Level 3 fair value is estimated by management using quotations 

obtained for the NRP Senior Notes on the closing trading prices near period end. 

(3)  The Level 3 fair value approximates the outstanding borrowing amount because the interest rates are variable and reflective 
of market rates and the terms of the credit facility allow the Partnership to repay this debt at any time without penalty.

101

 
 
 
NATURAL RESOURCE PARTNERS L.P.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—CONTINUED

(4)  The Level 3 fair value  is determined based on the present value of future cash flow projections related to the underlying 

assets. 

NRP has embedded derivatives in the Preferred Units related to certain conversion options, redemption features and the 
change of control provision that are accounted for separately from the Preferred Units as assets and liabilities at fair value in NRP's 
consolidated balance sheets. Level 3 valuation of the embedded derivatives are based on numerous factors including the likelihood 
of the event occurring. The embedded derivatives are revalued at each reporting period, and changes in their fair value would be 
recorded in Other income (expense) in NRP's Consolidated Statements of Comprehensive Income (Loss). The embedded derivatives 
had zero value at inception and as of December 31, 2017. 

Fair Value of Non-Financial Assets

The Partnership discloses or recognizes its non-financial assets, such as impairments of coal and aggregate properties and 
other assets, at fair value on a nonrecurring basis. Refer to Note 10. Plant and Equipment and Note 11. Mineral Rights for additional 
disclosures related to the fair value associated with the impaired assets.

15.    Related Party Transactions 

Cline Affiliates and Foresight Energy

Mr. Chris Cline, both individually and through another affiliate, Adena Minerals, LLC ("Adena"), owned a 31% interest in 
NRP's general partner, as well as approximately 0.5 million of NRP's common units through May 9, 2017. On May 9, 2017, Adena 
sold its 31% limited partner interest in NRP (GP) LP (the Partnership’s general partner) (“NRP GP”) to Great Northern Properties 
Limited Partnership (“GNPLP”) and Western Pocahontas Properties Limited Partnership ("WPPLP") (the “Adena Sale”). GNPLP 
and WPPLP are companies controlled by Corbin J. Robertson, the Chairman and Chief Executive Officer of GP Natural Resource 
Partners LLC (the general partner of NRP GP) (“GP LLC”). Upon closing of this transaction, NRP no longer considers the various 
companies affiliated with Chris Cline, including Foresight Energy to be affiliates of NRP. As a result, all transactions (including 
revenues, expenses and cash flows) after May 9, 2017, with the various companies affiliated with Chris Cline, including Foresight 
Energy, are considered to be third party transactions.

Various  subsidiaries  of  Foresight  Energy  lease  coal  reserves  from  the  Partnership,  and  the  Partnership  also  leases  coal 
transportation assets to them for a fee. Revenues related to these transactions with Foresight Energy are included in the Partnership's 
Consolidated Statement of Comprehensive Income (Loss) as follows:

During the year ended December 31, 2015, the Partnership recognized a gain of $9.3 million on a reserve swap at Foresight 
Energy's Williamson mine. The gain is included in Coal royalty and other—affiliates revenues on the Consolidated Statements of 
Comprehensive Income (Loss). The Level 3 fair value of the reserves was estimated using a discounted cash flow model. The 
expected cash flows were developed using estimated annual sales tons, forecasted sales prices and anticipated market royalty rates. 

In addition, NRP owns and leases a rail load out facility and owns a contractual overriding royalty interest at Foresight 
Energy's Sugar Camp mine. NRP's rail load out lease with a subsidiary of Foresight Energy is accounted for as a direct financing 
lease. Minimum lease payments are $5.0 million per year for the next five years and represent a $1.25 million per quarter in 
deficiency payment. NRP's contractual overriding royalty interest from a subsidiary of Foresight Energy provides for payments 
based upon production from specific tons at Foresight Energy's Sugar Camp operations. This overriding royalty is accounted for 
as a financing arrangement. Revenues from these transactions are included in Coal royalty and other revenues, including affiliates, 
in the table above.

The Partnership’s general partner does not receive any management fee or other compensation for its management of Natural 
Resource Partners L.P. However, in accordance with the partnership agreement, the general partner and its affiliates are reimbursed 
for services provided to the Partnership and for expenses incurred on the Partnership’s behalf. Employees of Quintana Minerals 
Corporation ("QMC") and WPPLP, affiliates of the Partnership, provide their services to manage the Partnership's business. QMC 
and WPPLP charge the Partnership the portion of their employee salary and benefits costs related to their employee services 
provided to NRP. These QMC and WPPLP employee management service costs and non-cash equity compensation expenses are 
presented as Operating and maintenance expenses—affiliates, net and General and administrative—affiliates on the Consolidated 
Statements  of  Comprehensive  Income  (Loss).  NRP  also  reimburses  overhead  costs  incurred  by  its  affiliates  to  manage  the 
Partnership's business. These overhead costs include certain rent, legal, accounting, treasury, information technology, insurance, 
administration of employee benefits and other corporate services incurred by or on behalf of the Partnership’s general partner and 
its affiliates and are presented as Operating and maintenance expenses—affiliates, net and General and administrative—affiliates 
on the Consolidated Statements of Comprehensive Income (Loss).

The  Partnership  had Accounts  payable—affiliates  to  QMC  of  $0.4  million  on  its  Consolidated  Balance  Sheets  at  both 
December 31, 2017 and 2016. Included in Current liabilities of discontinued operations on the Partnership's Consolidated Balance 
Sheets is less than $0.1 million in accounts payable due to QMC at both December 31, 2017 and 2016. The Partnership had 
Accounts payable—affiliates to WPPLP of $0.1 million and $0.6 million on its Consolidated Balance Sheets at December 31,

Quintana Capital Group GP, Ltd.

Corbin J. Robertson, Jr. is a principal in Quintana Capital Group GP, Ltd. ("Quintana Capital"), which controls several private 
equity funds focused on investments in the energy business. In connection with the formation of Quintana Capital, the Partnership 
adopted a formal conflicts policy that establishes the opportunities that will be pursued by the Partnership and those that will be 
pursued by Quintana Capital. The governance documents of Quintana Capital’s affiliated investment funds reflect the guidelines 
set forth in the Partnership's conflicts policy. At December 31, 2017, a fund controlled by Quintana Capital owned a substantial 
interest in Corsa Coal Corp. ("Corsa"), a coal mining company traded on the TSX Venture Exchange that is one of the Partnership’s 
lessees in Tennessee. Corbin J. Robertson III, one of the Partnership’s directors, was Chairman of the Board of Corsa through May 
10, 2017. 

Coal-related revenues from Corsa totaled $1.3 million, $2.2 million and $3.1 million for the years ended December 31, 2017, 
2016 and 2015, respectively and are included in Coal royalty and other—affiliates revenue in the Partnership's Statements of 
Comprehensive  Income  (Loss). The  Partnership  had Accounts  receivable—affiliates  totaling  $0.2  million  from  Corsa  at  both 
December 31, 2017 and 2016 on the Consolidated Balance Sheets.

WPPLP Production Royalty and Overriding Royalty

During the year ended December 31, 2017, 2016 and 2015, the Partnership recorded $1.5 million, $0.7 million and $0.4 
million in Operating and maintenance expenses—affiliates, respectively, on the Statements of Comprehensive Income (Loss) 
related to a non-participating production royalty payable to WPPLP pursuant to a conveyance agreement entered into in 2007. The 
Partnership had Other assets—affiliate from WPPLP of $0.2 million and $1.0 million at December 31, 2017 and December 31, 
2016, respectively on the Consolidated Balance Sheets related to a non-production royalty receivable from WPPLP for overriding 
royalty interest on a mine.

Quinwood Coal Company Royalty

In May 2017, a subsidiary of Alpha Natural Resources assigned two coal leases with the Partnership to Quinwood Coal 
Partners LP ("Quinwood"), an entity controlled by Corbin J. Robertson III. In connection with this lease assignment, Quinwood 
forfeited the historical recoupable balance related to this property. As a result, NRP recognized $0.9 million of deferred minimum 
payments received in prior periods from the subsidiary of Alpha as Coal royalty and other—affiliates revenue on the Statements 
of Comprehensive Income (Loss) during the year ended December 31, 2017. There were no deferred minimum payments received 
in  prior  periods  from  the  subsidiary  of Alpha  recognized  as  Coal  royalty  and  other—affiliates  revenue  on  the  Statements  of 
Comprehensive Income (Loss) during the year ended December 31, 2017.

Legal

NRP is involved, from time to time, in various legal proceedings arising in the ordinary course of business. While the ultimate 
results of these proceedings cannot be predicted with certainty, Partnership management believes these claims will not have a 
material effect on the Partnership’s financial position, liquidity or operations. NRP is also currently involved in the legal proceedings 
described below.

Anadarko Contingent Consideration Payment Dispute

In January 2013, NRP acquired a non-controlling 48.51% general partner interest in OCI Wyoming, L.P. ("OCI LP") and all 
of the preferred stock and a portion of the common stock of OCI Wyoming Co. ("OCI Co") (which in turn owned a 1% limited 
partner interest in OCI LP) from Anadarko Holding Company and its subsidiary, Big Island Trona Company (together, "Anadarko").  
The remaining general partner interest in OCI LP and common stock of OCI Co were owned by subsidiaries of OCI Chemical 
Corporation.

The acquisition agreement provided for additional contingent consideration of up to $50 million to be paid by the NRP if 
certain performance criteria were met at OCI LP as defined in the purchase and sale agreement in any of the years 2013, 2014 or 
2015. For those years, NRP paid an aggregate of $11.5 million to Anadarko in full satisfaction of these contingent consideration 
payment obligations.

In July 2013, pursuant to a series of transactions in connection with an initial public offering by a subsidiary of OCI Chemical 
Corporation, the ownership structure in OCI LP was simplified. In connection with such reorganization, NRP exchanged the stock 
of OCI Co for a limited partner interest in OCI LP. Following the reorganization, NRP's interest in OCI LP increased to 49%, 
consisting of both limited and general partner interests. The restructuring did not have any impact on the operations, revenues, 
management or control of OCI LP.

In July 2017, Anadarko filed a lawsuit against Opco and NRP Trona LLC alleging that the transactions conducted in 2013 
triggered  an  acceleration  of  NRP's  obligation  under  the  purchase  agreement  with  Anadarko  to  pay  additional  contingent 
consideration in full and demanded immediate payment of such amount, together with interest, court costs and attorneys’ fees. NRP 
does not believe the reorganization transactions triggered an obligation to pay any additional contingent consideration, and intends 
to vigorously defend this lawsuit. However, the ultimate outcome cannot be predicted with certainty given the early stage of this 
matter, and the Partnership estimates a possible range of loss between $0, if it prevails, and approximately $40 million, plus interest, 
court costs and attorneys’ fees if Anadarko prevails and is awarded the full damages it seeks.

Foresight Energy Disputes 

In November 2015, NRP filed a lawsuit against Foresight Energy’s subsidiary, Hillsboro Energy LLC ("Hillsboro") and has 
subsequently named Foresight Energy and certain of its other subsidiaries in that lawsuit. The lawsuit alleges, among other items, 
breach of contract by Hillsboro resulting from a wrongful declaration of force majeure at Hillsboro’s Deer Run mine, as well as 
alter-ego and tortious interference claims against Foresight Energy. In late March 2015, elevated carbon monoxide readings were 
detected at the Deer Run mine, and coal production at the mine was idled. In July 2015, Hillsboro declared a force majeure event 
under its lease with us, and Hillsboro has failed to make its contractually obligated minimum quarterly payments of $7.5 million 
since then. NRP believes the force majeure declaration by Hillsboro has no merit, and is vigorously pursuing recovery against 
Hillsboro as well as against Foresight Energy and certain of its other subsidiaries. Hillsboro has failed to make $76.0 million of 
required quarterly payments to NRP to date and such amount will continue to increase by $7.5 million for each quarter with respect 
to which payment is not made. 

In April  2016,  NRP  filed  a  lawsuit  against  Macoupin  Energy,  LLC  ("Macoupin"),  a  subsidiary  of  Foresight  Energy,  in 
Macoupin County, Illinois. The lawsuit alleges that Macoupin has failed to comply with the terms of its coal mining, rail loadout 
and rail loop leases by incorrectly recouping previously paid minimum royalties. As a result, Macoupin owes NRP approximately  
$9.5 million in improperly recouped minimum royalties through December 31, 2017.

Environmental Compliance

The operations the Partnership’s lessees conduct on its properties, as well as the aggregates/industrial minerals and oil and 
gas operations in which the Partnership has interests, are subject to federal and state environmental laws and regulations. See "Item 
1. Business—Regulation and Environmental Matters." As an owner of surface interests in some properties, the Partnership may 
be liable for certain environmental conditions occurring on the surface properties. The terms of substantially all of the Partnership’s 
coal leases require the lessee to comply with all applicable laws and regulations, including environmental laws and regulations. 
Lessees post reclamation bonds assuring that reclamation will be completed as required by the relevant permit, and substantially 
all of the leases require the lessee to indemnify the Partnership against, among other things, environmental liabilities. Some of 
these indemnifications survive the termination of the lease. The Partnership makes regular visits to the mines to ensure compliance 
with lease terms, but the duty to comply with all regulations rests with the lessees. The Partnership believes that its lessees will 
be able to comply with existing regulations and does not expect that any lessee’s failure to comply with environmental laws and 
regulations to have a material impact on the Partnership’s financial condition or results of operations. The Partnership has neither 
incurred, nor is aware of, any material environmental charges imposed on the Partnership related to its properties for the period 
ended December 31, 2017. The Partnership is not associated with any material environmental contamination that may require 
remediation costs. However, the Partnership’s lessees do conduct reclamation work on the properties under lease to them. Because 
the Partnership is not the permittee of the mines being reclaimed, the Partnership is not responsible for the costs associated with 
these reclamation operations. 

The Partnership is also responsible for losses and liabilities, including environmental liabilities that may arise from uninsured 
and underinsured events at its Construction Aggregates operations. Additionally, as a former owner of working interests in oil and 
natural gas operations, the Partnership is responsible for its proportionate share of any losses and liabilities, including environmental 
liabilities, arising from uninsured and underinsured events during the period it was an owner.

18.    Deferred Revenue and Deferred Revenue—Affiliate 

Most of the Partnership’s coal and aggregates lessees must pay the Partnership minimum annual or quarterly amounts which 
are generally recoupable out of actual production over certain time periods. These minimum payments are recorded as a deferred 
revenue liability when received. The deferred revenue attributable to the minimum payment is recognized as revenue based upon 
the underlying mineral lease when the lessee recoups the minimum payment through production or in the period immediately 
following the expiration of the lessee’s ability to recoup the payments. The Partnership’s deferred revenue (including affiliate) 
consists of the following:

Lease Modifications, Termination and Forfeitures of Minimum Royalty Balances

During the years ended December 31, 2017, 2016 and 2015, the Partnership entered into agreements with certain lessees to 
either modify or terminate existing coal-related leases that resulted in the Partnership recognizing $3.4 million, $40.5 million, and 
less than $0.1 million of deferred revenue as revenue, respectively.

19.    Unit-Based Compensation 

GP  Natural  Resource  Partners  LLC  adopted  the  Natural  Resource  Partners  Long-Term  Incentive  Plan  (the  "Long-Term 
Incentive Plan") for directors of GP Natural Resource Partners LLC and employees of its affiliates who perform services for the 
Partnership. The Compensation, Nominating and Governance Committee ("CNG Committee") of GP Natural Resource Partners 
LLC’s board of directors (the "Board") administers the Long-Term Incentive Plan. Subject to the rules of the exchange upon which 
the common units are listed at the time, the Board and the CNG Committee have the right to alter or amend the Long-Term Incentive 
Plan or any part of the Long-Term Incentive Plan from time to time. Except upon the occurrence of unusual or nonrecurring events, 
no change in any outstanding grant may be made that would materially reduce the benefit intended to be made available to a 
participant without the consent of the participant.

Phantom units are incentive based equity awards issued to employees over a vesting period that entitle the grantee to receive 
the cash equivalent to the value of a unit of the Parent common units upon each vesting. The Partnership records compensation 
cost  equal  to  the  fair  value  of  the  award  at  the  measurement  date,  which  is  determined  to  be  the  earlier  of  the  performance 
commitment date or the service completion date. In addition, compensation cost for unvested phantom unit awards is adjusted 
each reporting period for any changes in the Partnership’s unit price. Under the plan a grantee will receive the market value of a 
common unit in cash upon vesting. Market value is defined as the average closing price over the 20 trading days prior to the vesting 
date. The compensation committee may make grants under the Long-Term Incentive Plan to employees and directors containing 
such terms as it determines, including the vesting period. Outstanding grants vest upon a change in control of the Partnership, the 
general partner, or GP Natural Resource Partners LLC. If a grantee’s employment or membership on the board of directors terminates 
for any reason, outstanding grants will be automatically forfeited unless and to the extent the compensation committee provides 
otherwise. 

107

 
NATURAL RESOURCE PARTNERS L.P.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—CONTINUED

In  connection  with  the  phantom  unit  awards,  the  CNG  Committee  also  granted  tandem  Distribution  Equivalent  Rights 
("DERs"), which entitle the holders to receive distributions equal to the distributions paid on the Partnership’s common units 
between the date the units are granted and the vesting date. The DERs are payable in cash upon vesting but may be subject to 
forfeiture if the grantee ceases employment prior to vesting.

A summary of activity in the outstanding grants during 2017 is as follows:

Grants typically vest at the end of a four-year period and are paid in cash upon vesting. The grant date fair value was $4.2 
million for awards in 2015. There were no new awards issued in 2016 or 2017. The Partnership recognized compensation expense 
(benefit)  of  $0.3  million,  $1.4  million  and  $(3.4)  million  included  in  Operating  and  maintenance  expenses  and  General  and 
administrative expenses on its Consolidated Statements of Comprehensive Income (Loss) for the years ended December 31, 2017, 
2016 and 2015, respectively. Compensation expense includes the amortization of the awards over the vesting period and changes 
in the market price of the Partnership's common units during the period. The unamortized cost associated with unvested outstanding 
grants and related DERs at December 31, 2017 and December 31, 2016, was $0.2 million and $0.8 million, respectively.

In connection with the Long-Term Incentive Plans, cash payments are typically made during the first quarter of the year. 
Payments of $1.8 million, $1.5 million and $4.4 million were made during the years ended December 31, 2017, 2016, and 2015, 
respectively.

ITEM 9A.  CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

We carried out an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures (as 
defined in Rule 13a-15(e) of the Exchange Act) as of December 31, 2017. This evaluation was performed under the supervision 
and with the participation of our management, including the Chief Executive Officer and Chief Financial Officer of GP Natural 
Resource Partners LLC, our managing general partner. Based upon that evaluation, the Chief Executive Officer and Chief Financial 
Officer concluded that these disclosure controls and procedures were effective as of December 31, 2017 at the reasonable assurance 
level in producing the timely recording, processing, summary and reporting of information and in accumulation and communication 
of information to management to allow for timely decisions with regard to required disclosures.

Management’s Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such 
term is defined in Exchange Act Rules 13a-15(f) and 15d-15(f). Under the supervision and with the participation of our management, 
including the Chief Executive Officer and Chief Financial Officer of GP Natural Resource Partners LLC, our managing general 
partner, we conducted an evaluation of the effectiveness of our internal control over financial reporting as of December 31, 2017 
based on the framework in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the 
Treadway  Commission  "2013  Framework"  (COSO).  Based  on  that  evaluation,  as  of  December 31,  2017,  our  management 
concluded that our internal control over financial reporting was effective at a reasonable assurance level based on those criteria. 
No changes were made to our internal control over financial reporting during the last fiscal quarter that materially affected, or are 
reasonably likely to materially affect, our internal control over financial reporting.

Ernst & Young, LLP, the independent registered public accounting firm who audited the Partnership’s consolidated financial 
statements included in this Annual Report on Form 10-K, has issued a report on the Partnership’s internal control over financial 
reporting, which is included herein.

Opinion on Internal Control over Financial Reporting

We have audited Natural Resource Partners L.P.’s internal control over financial reporting as of December 31, 2017, based on 
criteria  established  in  Internal  Control—Integrated  Framework  issued  by  the  Committee  of  Sponsoring  Organizations  of  the 
Treadway Commission (2013 framework) (the COSO criteria). In our opinion, Natural Resource Partners L.P. (the Partnership) 
maintained, in all material respects, effective internal control over financial reporting as of December 31, 2017, based on the COSO 
criteria.

We  also  have  audited,  in  accordance  with  the  standards  of  the  Public  Company Accounting  Oversight  Board  (United  States) 
(PCAOB), the consolidated balance sheets of Natural Resource Partners L.P. as of December 31, 2017 and 2016, and the related 
consolidated statements of comprehensive income (loss), partners’ capital and cash flows for each of the three years in the period 
ended December 31, 2017, and related notes and our report dated March 1, 2018 expressed an unqualified opinion thereon.

Basis for Opinion

The  Partnership’s  management  is  responsible  for  maintaining  effective  internal  control  over  financial  reporting  and  for  its 
assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Report 
on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Partnership’s internal control over 
financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent 
with respect to the Partnership in accordance with the U.S. federal securities laws and the applicable rules and regulations of the 
Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the 
audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material 
respects.

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness 
exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing 
such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for 
our opinion.

Definition and Limitations of Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability 
of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted 
accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain 
to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets 
of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial 
statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are 
being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable 
assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that 
could have a material effect on the financial statements.

Because  of  its  inherent  limitations,  internal  control  over  financial  reporting  may  not  prevent  or  detect  misstatements. Also, 
projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because 
of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Board Meetings and Executive Sessions

The Board met 10 times in 2017. During 2017, our non-management directors met in executive session several times. The 
presiding  director  was  Mr. Vecellio,  the  Chairman  of  our  Compensation,  Nominating  and  Governance  Committee,  or  CNG 
Committee. In addition, our independent directors met one time in executive session in December 2017. Mr. Vecellio was the

the Chairman of the CNG Committee, NRP Board of Directors, 1201 Louisiana Street, Suite 3400, Houston, Texas 77002.

Independence of Directors

The Board of Directors has affirmatively determined that Messrs. Blakely, Gordy, Karn, Navarre, Smith and Vecellio are 
independent based on all facts and circumstances considered by the Board, including the standards set forth in Section 303A.02(a) 
of the NYSE’s listing standards. Although we had a majority of independent directors in 2017, because we are a limited partnership 
as defined in Section 303A of the NYSE’s listing standards, we are not required to do so. The Board has an Audit Committee, a 
Compensation, Nominating and Governance Committee, and a Conflicts Committee, each of which is staffed solely by independent 
directors.

117

Audit Committee

Our Audit Committee is currently comprised of Mr. Smith, who serves as chairman, Mr. Gordy and Mr. Navarre. Mr. Smith 
and Mr. Navarre are "Audit Committee Financial Experts" as determined pursuant to Item 407 of Regulation S-K. During 2017, 
the Audit Committee met seven times. Mr. Gordy joined the Audit Committee effective January 1, 2018. Mr. Blakely and Mr. Karn 
each served as members of the Audit Committee during the full calendar year of 2017.  Both Mr. Blakley and Mr. Karn are "Audit 
Committee Financial Experts" as determined pursuant to Item 407 of Regulation S-K.

Report of the Audit Committee

Our Audit  Committee  is  composed  entirely  of  independent  directors.  The  members  of  the Audit  Committee  meet  the 
independence and experience requirements of the New York Stock Exchange. The Audit Committee has adopted, and annually 
reviews, a charter outlining the practices it follows. The charter complies with all current regulatory requirements. The Audit 
Committee Charter is available on our website at www.nrplp.com and is available in print upon request.

During 2017, at each of its meetings, the Audit Committee met with the senior members of our financial management team, 
our general counsel and our independent auditors. The Audit Committee had private sessions at certain of its meetings with our 
independent auditors and the senior members of our financial management team and the general counsel at which candid discussions 
of financial management, accounting and internal control and legal issues took place.

The Audit Committee approved the engagement of Ernst & Young LLP as our independent auditors for the year ended 
December 31, 2017 and reviewed with our financial managers and the independent auditors overall audit scopes and plans, the 
results of internal and external audit examinations, evaluations by the auditors of our internal controls and the quality of our 
financial reporting.

Management has reviewed the audited financial statements in the Annual Report with the Audit Committee, including a 
discussion of the quality, not just the acceptability, of the accounting principles, the reasonableness of significant accounting 
judgments and estimates, and the clarity of disclosures in the financial statements. In addressing the quality of management’s 
accounting judgments, members of the Audit Committee asked for management’s representations and reviewed certifications 
prepared by the Chief Executive Officer and Chief Financial Officer that our unaudited quarterly and audited consolidated financial 
statements fairly present, in all material respects, our financial condition and results of operations, and have expressed to both 
management and auditors their general preference for conservative policies when a range of accounting options is available.

The Committee also discussed with the independent auditors other matters required to be discussed by the auditors with the 
Committee by PCAOB Auditing Standard No. 16, Communications With Audit Committees. The Committee received and discussed 
with the auditors their annual written report on their independence from the partnership and its management, which is made under 
Rule  3526,  Communication  With Audit  Committees  Concerning  Independence,  and  considered  with  the  auditors  whether  the 
provision of non-audit services provided by them to the partnership during 2017 was compatible with the auditors’ independence.

In performing all of these functions, the Audit Committee acts only in an oversight capacity. The Audit Committee reviews 
our  Quarterly  Reports  on  Form 10-Q  and Annual  Reports  on  Form 10-K  prior  to  filing  with  the  Securities  and  Exchange 
Commission. In 2017, the Audit Committee also reviewed quarterly earnings announcements with management and representatives 
of the independent auditor in advance of their issuance. In its oversight role, the Audit Committee relies on the work and assurances 
of our management, which has the primary responsibility for financial statements and reports, and of the independent auditors, 
who, in their report, express an opinion on the conformity of our annual financial statements with U.S. generally accepted accounting 
principles.

In  reliance  on  these  reviews  and  discussions,  and  the  report  of  the  independent  auditors,  the  Audit  Committee  has 
recommended to the Board of Directors, and the Board has approved, that the audited financial statements be included in our 
Annual Report on Form 10-K for the year ended December 31, 2017, for filing with the Securities and Exchange Commission.

Compensation, Nominating and Governance Committee

Executive officer compensation is administered by the CNG Committee, which is currently comprised of three members: 
Mr. Vecellio, as Chairman, Mr. Gordy and Mr. Smith. Mr. Smith joined the CNG Committee effective January 1, 2018. Messrs. 
Blakely and Karn each served on the CNG Committee for the full calendar year of 2017. The CNG Committee has reviewed and 
approved the compensation arrangements described in the Compensation Discussion and Analysis section of this Annual Report 
on Form 10-K. During 2017, the CNG Committee met eight times. Our Board of Directors appoints the CNG Committee and 
delegates to the CNG Committee responsibility for:

• 

• 

reviewing and approving the compensation for our executive officers in light of the time that each executive officer allocates 
to our business;

reviewing and recommending the annual and long-term incentive plans in which our executive officers participate and 
approving awards thereunder; and

• 

reviewing and approving compensation for the Board of Directors.

Our Board of Directors has determined that each CNG Committee member is independent under the listing standards of the 

NYSE and the rules of the SEC.

Pursuant to its charter, the CNG Committee is authorized to obtain at NRP’s expense compensation surveys, reports on the 
design and implementation of compensation programs for directors and executive officers and other data that the CNG Committee 
considers as appropriate. In addition, the CNG Committee has the sole authority to retain and terminate any outside counsel or 
other experts or consultants engaged to assist it in the evaluation of compensation of our directors and executive officers. The 
CNG Committee Charter is available in print upon request.

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Exchange Act requires directors, officers and persons who beneficially own more than ten percent of a 
registered class of our equity securities to file with the SEC and the NYSE initial reports of ownership and reports of changes in 
ownership of their equity securities. These people are also required to furnish us with copies of all Section 16(a) forms that they 
file. Based solely upon a review of the copies of Forms 3, 4 and 5 furnished to us, or written representations from certain reporting 
persons that no Forms 5 were required for transactions occurring in 2016, and we believe that, except as provided below, our 
officers and directors and persons who beneficially own more than ten percent of a registered class of our equity securities complied 
with all filing requirements with respect to transactions in our equity securities during 2017. On February 16, 2017, Mr. Blakely 
filed a Form 4 reporting the vesting of 370 phantom units on February 13, 2017 that had not been previously reported on a timely 
basis as a result of a technical issue with his Edgar filing codes.

Partnership Agreement

Investors  may  view  our  partnership  agreement  and  the  amendments  to  the  partnership  agreement  on  our  website  at 
www.nrplp.com. The partnership agreement is also filed with the SEC and is available in print to any unitholder that requests them.

Corporate Governance Guidelines and Code of Business Conduct and Ethics

We have adopted Corporate Governance Guidelines. We have also adopted a Code of Business Conduct and Ethics that 
applies to our management, and complies with Item 406 of Regulation S-K. Our Corporate Governance Guidelines and our Code 
of Business Conduct and Ethics are available on our website at www.nrplp.com and are available in print upon request.

NYSE Certification

Pursuant to Section 303A of the NYSE Listed Company Manual, in 2017, Corbin J. Robertson, Jr. certified to the NYSE 

that he was not aware of any violation by the Partnership of NYSE corporate governance listing standards.

ITEM 11.  EXECUTIVE COMPENSATION

Limited  Partnership  (“Western  Pocahontas”).  Quintana  and  Western  Pocahontas  are  controlled  by  our  Chairman  and  Chief 
Executive Officer and are affiliates of NRP. While our executive officers are employed by affiliates of NRP, each of them has been 
appointed to serve as an executive officer of GP Natural Resource Partners LLC (“GP LLC”), the general partner of NRP (GP) 
LLC (“NRP GP”), the general partner of NRP. For a more detailed description of our structure, see “Item 1. Business—Partnership 
Structure and Management” in this Annual Report on Form 10-K.

Although our executives’ salaries and bonuses are paid directly by the private companies that employ them, we reimburse 
those companies based on the time allocated to NRP by each executive officer. Our reimbursement for the compensation of executive 
officers  is  governed  by  our  partnership  agreement.  For  purposes  of  this  Compensation  Discussion  and Analysis,  our  “named 
executive officers” are:

•  Corbin J. Robertson, Jr.—Chairman and Chief Executive Officer

•  Craig W. Nunez—President and Chief Operating Officer (former Chief Financial Officer and Treasurer)

•  Kathryn S. Wilson—Vice President, General Counsel and Secretary

•  Christopher J. Zolas—Chief Financial Officer and Treasurer (former Chief Accounting Officer)

•  Kevin J. Craig—Executive Vice President—Coal

•  Wyatt L. Hogan—Former President and Chief Operating Officer

Effective as of August 8, 2017, Wyatt L. Hogan resigned from his position as President and Chief Operating Officer of GP 
Natural Resource Partners LLC. Effective as of the same date, Craig W. Nunez, who previously served as Chief Financial Officer 
and Treasurer of GP LLC, became President and Chief Operating Officer of GP LLC and Christopher J. Zolas, who previously 
served as Chief Accounting Officer of GP LLC, became Chief Financial Officer and Treasurer of GP LLC.

Executive Officer Compensation Strategy and Philosophy

Under our partnership agreement, we are required to distribute all of our available cash each quarter. Historically, our primary 
business objective was to generate cash flows at levels that could sustain long-term quarterly cash distributions to our investors. 
However, given the difficult coal markets over the past few years, coupled with the limitations on our ability to access capital from 
additional sources, our current objective is to preserve long-term equity value for our unitholders by using our excess free cash 
flow to reduce our leverage. Our objective in determining the compensation of our executive officers is to retain qualified people 
to manage the business through a difficult market cycle. Although we historically have not tied our compensation to achievement 
of specific financial targets or fixed performance criteria, we have reevaluated that strategy in light of current market conditions. 
See “—2016 Cash Long-Term Incentive Plan” and “—2017 Long-Term Incentive Plan” below.

The 2017 compensation for executive officers consisted of four primary components:

• 

• 

• 

• 

base salaries;

short-term cash incentive compensation;

long-term cash incentive compensation; and

perquisites and other benefits.

120

In December 2016, our CNG Committee reviewed the performance of the executive officers and the amount of time expected 
to be spent by each NRP officer on NRP business, and determined the salaries for each officer for 2017. All of our named executive 
officers, other than Corbin J. Robertson, Jr., our Chairman and Chief Executive Officer, Kathryn S. Wilson, our Vice President, 
General Counsel and Secretary, and Kevin J. Craig, our Executive Vice President —Coal, spent 100% of their time on NRP matters 
during 2017, and NRP bears the proportionate cost of their time. Mr. Robertson does not receive a salary or an annual bonus in 
his capacity as Chief Executive Officer. Rather, Mr. Robertson has historically been compensated exclusively through long-term 
incentive awards.

Historically, in February of each year, the CNG Committee has approved the year-end bonuses for the year just ended and 
long-term incentive awards for the executive officers. The CNG Committee considers the performance of the partnership, the 
performance of the individuals and the outlook for the future in determining the amounts of the awards. Prior to 2016, we issued 
phantom units, coupled with tandem distribution equivalent rights (“DERs”), to our executive officers that are paid in cash based 
on the average closing price of our common units for the 20-day trading period prior to vesting. The phantom units and DERs 
typically vest four years from the date of grant. In past years, these awards have served to align the executive officers’ interests 
with those of our unitholders.

Prior to 2017, our general partner would use a portion of the annual cash distributions it received on the NRP common units 
held by our general partner for awards to our executive officers. We referred to this as the “GP Bonus Award” program.  Mr. Robertson 
determined the awards allocated to each executive officer in his sole discretion, but the award amounts were reviewed by the CNG 
Committee and taken into account when making officer compensation determinations. During 2017, Mr. Robertson determined 
to discontinue the GP Bonus Award program beginning with respect to the year ended December 31, 2017.

In February 2016, the Board adopted a cash long-term incentive plan and made time-based and performance-based awards 
to officers under the plan in March 2016. In March 2017, the Board determined that the conditions to the vesting of the performance 
awards under the 2016 cash incentive plan had been met as a result of the completion of the 2017 recapitalization transactions. 
See  “—2016  Cash  Long-Term  Incentive  Plan”  below.  Following  completion  of  the  recapitalization  transactions,  the  Board 
determined to evaluate options for a new long-term incentive plan that would result in officers and directors being awarded equity 
in NRP. See “—2017 Long-Term Incentive Plan” below.

2016 Cash Long-Term Incentive Plan

In February 2016, the CNG Committee adopted a new cash-based long-term incentive plan (the “2016 Cash LTIP”) and 
recommended the new plan and awards thereunder to the non-management members of the Board for approval. The Board approved 
the 2016 Cash LTIP and the forms of long-term incentive award agreements in February 2016. Two types of cash incentive awards 
were made to the executive officers in March 2016: (1) time vesting awards, 50% of which vested in February 2017 and 50% of 
which vested in February 2018, and (2) performance-based awards that provided that such awards would vest 50% upon the 
repayment,  refinancing  or  rollover  of  the  Opco  revolving  credit  facility  that  would  mature  in April  2018  and  50%  upon  the 
repayment, refinancing or rollover of NRP’s 9.125% Senior Notes that would be due in October 2018, in each case as determined 
by the Board and depending upon the continued employment of the applicable executive officer. The performance-based awards 
vested in full in 2017 upon the completion of the recapitalization transactions. The performance awards also provided that up to 
an additional 100% of the amount of the performance-based awards may be awarded to the executive officers in the sole discretion 
of the Board after considering additional performance criteria including, but not limited to, NRP’s common unit price, projected 
EBITDA, and leverage ratio. As described in greater detail below under “—Evaluation of 2017 Performance; Components of 
Compensation—Long-Term Incentive Cash Compensation,” an additional 100% of the performance-based awards was awarded 
by the Board in March 2017.

2017 Long-Term Incentive Plan

Following completion of the recapitalization transactions, the Board directed the CNG Committee to evaluate a new long-
term incentive program that would continue to incentivize management while also align the long-term interests of management 
with the interests of NRP’s unitholders. In December 2017, the CNG Committee approved and the Board adopted the Natural 
Resource Partners 2017 Long-Term Incentive Plan (the “2017 LTIP”), subject to unitholder approval. On December 20, 2017, 
unitholders holding the requisite percentage of votes necessary to approve the 2017 LTIP approved the 2017 LTIP by written 
consent in lieu of a special meeting of unitholders. The 2017 LTIP became effective on January 16, 2018. On February 14, 2018, 
the CNG Committee made awards of common units and phantom units to be settled in common units under the 2017 LTIP to 
NRP’s officers and directors. 

121

Role of Compensation Experts

Historically, the CNG Committee periodically has utilized consultants to get a basic sense of the market, but has considered 
the advice of the consultant as only one of many factors among the other items discussed in this compensation discussion and 
analysis. Neither the Board, nor the CNG Committee retained any consultants to evaluate compensation of officers or directors in 
2017.  

Role of Our Executive Officers in the Compensation Process

With respect to 2017 salaries and vesting of the performance awards under the 2016 Cash LTIP, Mr. Hogan, our former 
President and Chief Operating Officer, provided Mr. Robertson with recommendations relating to the executive officers other than 
himself. Mr. Robertson considered those recommendations and provided the CNG Committee and Board with recommendations 
for all of the executive officers other than himself. Mr. Robertson relied on his personal experience in setting compensation over 
a number of years in determining the appropriate amounts for each employee, and considered each of the factors described elsewhere 
in this compensation discussion and analysis. Mr. Robertson and Mr. Hogan attended the CNG Committee and Board meetings at 
which the Committee deliberated and approved the 2017 salaries and performance award vesting, as applicable, but were excused 
from the meetings when the CNG Committee and Board, as applicable, discussed their compensation. 

With respect to 2017 short-term cash incentive compensation, Mr. Nunez, provided Mr. Robertson with recommendations 
relating to the executive officers other than himself. Mr. Robertson considered those recommendations and provided the CNG 
Committee  with  recommendations  for  all  of  the  executive  officers  other  than  himself.  Mr. Robertson  relied  on  his  personal 
experience  in  setting  compensation  over  a  number  of  years  in  determining  the  appropriate  amounts  for  each  employee,  and 
considered each of the factors described elsewhere in this compensation discussion and analysis. Mr. Robertson and Mr. Nunez 
attended  the  CNG  Committee  meetings  at  which  the  Committee  deliberated  and  approved  the  short-term  cash  incentive 
compensation, but were excused from the meetings when the CNG Committee discussed their compensation. 

Components of Compensation

Base Salaries

With the exception of Mr. Robertson, who, as described above, does not receive a salary for his services as Chief Executive 
Officer, our executive officers are paid an annual base salary by Quintana or Western Pocahontas for services rendered to us by 
the executive officers during the fiscal year. We then reimburse Quintana and Western Pocahontas based on the time allocated by 
each executive officer to our business. The base salaries of our named executive officers are reviewed on an annual basis as well 
as at the time of a promotion or other material change in responsibilities. The CNG Committee reviews and approves the full 
salaries paid to each executive officer by Quintana and Western Pocahontas, based on both the actual time allocations to NRP in 
the prior year and the anticipated time allocations in the coming year. Adjustments in base salary are based on an evaluation of 
individual performance, our partnership’s overall performance during the fiscal year and the individual’s contribution to our overall 
performance.

In determining salaries for NRP’s executive officers for 2017, at the December 2016 meeting, the CNG Committee considered 
the financial performance of NRP for the nine months ended September 30, 2016 as well as the projected financial performance 
of NRP for the fourth quarter of 2016 and for the year ending December 31, 2017. The CNG Committee also considered the 
individual performance of each member of the executive management team during 2016. Salaries for 2017 were held flat over 
2016 salaries and are shown in the Summary Compensation Table below.

Short-Term Cash Incentive Compensation

Each named executive officer, with the exception of Mr. Robertson, received a discretionary short-term cash incentive award 
approved in February 2018 by the CNG Committee based on similar criteria used to evaluate the annual base salaries. The amounts 
awarded with respect to 2017 under this program are disclosed in the Summary Compensation Table under the Bonus column. As 
with the base salaries, there are no formulas or specific performance targets related to these awards. The short-term cash incentive 
awards with respect to 2017 were generally lower than 2016 amounts due to vesting of the cash performance awards during 2017, 
as described below.

122

Long-Term Cash Incentive Compensation

In March 2017, one-half of the time-based awards granted under the 2016 Cash LTIP vested and were paid. In addition, 
following the completion of the March 2017 recapitalization transactions, on March 3, 2017, the Board determined that both vesting 
conditions of the performance awards made under the 2016 Cash LTIP had been met and therefore the target performance award 
grant amounts would be awarded to each executive officer.  In addition, following consideration of additional performance criteria 
including, but not limited to: (1) the performance of NRP’s common units over the past twelve months and subsequent to the 
announcement of the transactions; (2) the 2016 and projected 2017 EBITDA for NRP; and (3) the current and projected leverage 
ratios for NRP and its subsidiaries, the Board determined to award an additional 100% of the amount of the performance-based 
awards to the executive officers. The amounts paid to the named executive officers were equal to 200% of the performance award 
grant amounts. Amounts vested and paid under the 2016 Cash LTIP are shown in the Summary Compensation Table under the 
Non-Equity Incentive Plan column. 

Perquisites and Other Personal Benefits

Both  Quintana  and  Western  Pocahontas  maintain  employee  benefit  plans  that  provide  our  executive  officers  and  other 
employees with the opportunity to enroll in health, dental and life insurance plans. Each of these benefit plans require the employee 
to pay a portion of the health and dental premiums, with the company paying the remainder. These benefits are offered on the same 
basis to all employees of Quintana and Western Pocahontas, and the company costs are reimbursed by us to the extent the employee 
allocates time to our business.

Quintana and Western Pocahontas also maintain tax-qualified 401(k) and defined contribution retirement plans. During 2017, 
Quintana matched 100% of the first 4.5% of the employee contributions under the 401(k) plan and Western Pocahontas matched 
the employee contributions at a level of 100% of the first 3% of the contribution and 50% of the next 3% of the contribution. In 
addition, each company contributed 1/12 of each employee’s base salary to the defined contribution retirement plan. As with the 
other contributions, any amounts contributed by Quintana and Western Pocahontas are reimbursed by us based on the time allocated 
by the employee to our business. None of NRP, Quintana or Western Pocahontas maintains a pension plan or a defined benefit 
retirement plan.

Unit Ownership Requirements

We have not historically had any policy or guidelines that require specified ownership of our common units by our directors 

or executive officers or unit retention guidelines.  

In December 2017, in connection with the adoption of the 2017 LTIP, the Board adopted the Natural Resource Partners L.P. 
Unit Ownership and Retention Guidelines (the “ownership guidelines”), which will be administered by the CNG Committee. The 
ownership guidelines require NRP’s officers who are required to file ownership reports under Section 16 of the Securities Exchange 
Act of 1934 (the “Exchange Act”) and certain other officers as designated from time-to-time by the Board or the CNG Committee 
to retain all common units awarded under any NRP incentive plan (net of any units withheld or sold to cover tax liabilities) until 
certain ownership guidelines are met. The guideline for NRP’s President and Chief Operating Officer is for such individual to hold 
common units having a value of four times his or her base salary at the date of measurement. The guideline for the other officers 
subject to the ownership guidelines is for each such individual to hold common units having a value of three times his or her base 
salary at the date of measurement. There is no minimum time period required to achieve the unit ownership guidelines. Due to his 
substantial ownership in us, the ownership guidelines do not currently apply to our Chief Executive Officer.

The ownership guidelines also require directors who are not officers to retain common units with a value equal to three times 
the amount of the annual cash retainer paid to directors. Directors are required to achieve the unit ownership guideline within five 
years. Until the unit ownership guideline is achieved, each director is encouraged to retain all common units awarded under any 
NRP incentive plan (net of any units sold to cover tax liabilities).

Units that count towards the satisfaction of the officer and director guidelines include common units held directly by the 
executive officer or director, common units owned indirectly by the executive officer or director (e.g, by a spouse or other immediate 
family member residing in the same household or a trust for the benefit of the executive officer or director or his or her family), 
units granted under NRP’s long-term incentive plans (including phantom units representing the right to receive units), and units 
purchased in the open market (whether purchased before or after the effective date of the ownership guidelines).

123

Incentive Compensation Recoupment Policy

We have not historically had any policy or guidelines regarding recoupment or adjustment of compensation of our executive 
officers. In December 2017, in connection with the adoption of the 2017 LTIP, the Board adopted the Natural Resource Partners 
L.P. Incentive Compensation Recoupment Policy, which will be administered by the CNG Committee. The policy authorizes the 
Board or committee thereof to recoup incentive compensation in the event of a restatement of financial statements due to material 
non-compliance with securities laws, fraud or misconduct.

Securities Trading Policy

Our insider trading policy states that executive officers and directors may not purchase or sell puts or calls to sell or buy our 

common units, engage in short sales with respect to our common units, or buy our securities on margin.

Report of the Compensation, Nominating and Governance Committee

The CNG Committee has reviewed and discussed the Compensation Discussion and Analysis required by Item 402(b) of 
Regulation S-K with management. Based on the reviews and discussions referred to in the foregoing sentence, the CNG Committee 
recommended to the Board that the Compensation Discussion and Analysis be included in this Annual Report on Form 10-K for 
the year ended December 31, 2017.

Grants of Plan-Based Awards in 2017

No plan-based awards were granted during the year ended December 31, 2017.

Employment Agreements

Following  his  resignation  as  President  and  Chief  Operating  Officer,  Mr. Hogan  and  Quintana  entered  into  a  two-year 
employment agreement dated August 15, 2017, pursuant to which Mr. Hogan continued to be employed by Quintana and agreed 
to continue to provide services to NRP. The employment agreement provides for Mr. Hogan to receive an annualized salary of 
$500,000 beginning August 15, 2017 through the end of the two-year term and the same health benefits that he received during 
his time as an officer of NRP, all of the costs of which are borne by NRP.  Mr. Hogan’s employment with Quintana terminated in 
February 2018, and Mr. Hogan received his 2017 bonus of $250,000 at that time pursuant to the terms of the employment agreement. 
The  employment  agreement  also  provides  that  Mr.  Hogan  will  continue  to  receive  his  salary  for  the  remaining  term  of  his 
employment agreement, and that all of his outstanding phantom units and cash incentive awards will be vested on the date of 
termination and settle in accordance with the terms of such awards.

than benefits payable to Mr. Hogan pursuant to his employment agreement. Upon the occurrence of a change in control of NRP, 
our general partner, or GP Natural Resource Partners LLC, both the outstanding phantom unit awards and the outstanding cash 
incentive awards held by each of our named executive officers would immediately vest and become payable. The table below

Directors’ Compensation for the Year Ended December 31, 2017

During the year ended December 31, 2017, there were a number of changes to the Board and the committees thereof:

•  Effective March 2, 2017, Jasvinder S. Khaira joined the Board as the designee of Blackstone pursuant to the Board 

Representation and Observation Rights Agreement;

•  Effective April 1, 2017, Mr. Karn resigned as Chairman of the Audit Committee, and Stephen P. Smith became Chairman 

of that Committee; 

•  Effective  April  1,  2017,  Mr.  Blakely  resigned  as  Chairman  of  the  Compensation,  Nominating  and  Governance 

Committee, and Leo A. Vecellio, Jr. became Chairman of that Committee;

•  Effective May 9, 2017, Trey Jackson, resigned from the Board in connection with the sale by Adena Minerals, LLC of 

its 31% interest in our general partner to affiliates of ours; and

•  Effective December 31, 2017, Robert T. Blakely and Robert B. Karn, III each retired from the Board in accordance 

with the age requirements of NRP’s Corporate Governance Guidelines.

127

For more information regarding the Board and committees thereof, see “Item 10. Directors and Executive Officers of the 

Managing General Partner and Corporate Governance” elsewhere in this Annual Report on Form 10-K.  

In December 2016, the Board approved an annual cash retainer payment of $60,000 to each non-employee director, plus 
annual committee fees equal to $10,000 in cash for each committee chairman and $5,000 in cash for each committee member. 
Following completion of the 2017 recapitalization transactions, each non-employee director (other than Mr. Khaira) received a 
bonus of $25,000 to compensate them for the additional time spent on NRP matters in connection with those transactions. In 
October 2017, the Board reviewed total Board compensation and determined to increase the annual retainer to $150,000 effective 
for the year ended December 31, 2017. Factors considered in increasing the annual retainer included the fact that the Board cash 
retainer had remained at $60,000 since 2011, the fact that NRP had not issued any phantom units since 2015, market rates for 
public company directorships, and the need to retain additional directors following the retirements of Messrs. Blakely and Karn 
at the end of 2017.  

The table below shows the directors’ compensation for the year ended December 31, 2017.

Compensation Committee Interlocks and Insider Participation

During the year ended December 31, 2017, Messrs. Blakely, Gordy, Karn and Vecellio served on the CNG Committee. None 
of Messrs. Blakely, Gordy, Karn or Vecellio has ever been an officer or employee of NRP or GP Natural Resource Partners LLC. 
None of our executive officers serve as a member of the board of directors or compensation committee of any entity that has any 
executive officer serving as a member of our Board or CNG Committee.

Pay Ratio Disclosure 

The Securities and Exchange Commission has adopted a rule requiring annual disclosure of the ratio of the median employee’s 

total annual compensation to the total annual compensation of the CEO.  

The personnel providing services to our Construction Aggregates business are employed by consolidated subsidiaries of 
ours. Other personnel providing services to us, including our executive officers, are employed by Quintana or Western Pocahontas 
and consequently, are not considered our employees for purposes of calculating the required pay ratio. We identified the median 
employee by examining the 2017 total taxable compensation, as reflected in our payroll records as reported to the Internal Revenue 
Service on Form W-2, for all individuals, who were employed by our consolidated subsidiaries on December 31, 2017. We included 
all employees of our Construction Aggregates business, whether employed on a full-time, part-time, temporary or seasonal basis. 
As of December 31, 2017, we employed 243 such persons. We did not make any assumptions, adjustments, or estimates with 
respect to total cash compensation or equity compensation and we did not annualize the compensation for any employees that 
were not employed for all of 2017. 

129

 
 
 
After identifying the median employee based on total compensation, we calculated annual 2017 compensation for the median 
employee using the same methodology used to calculate the Chief Executive Officer’s total compensation as reflected in the 
Summary Compensation Table above. The median employee’s annual 2017 compensation was as follows:

ITEM 13.  CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS, AND DIRECTOR INDEPENDENCE 

Western Pocahontas Properties Limited Partnership, New Gauley Coal Corporation and Great Northern Properties Limited 
Partnership are three privately held companies that are primarily engaged in owning and managing mineral properties. We refer 
to these companies collectively as the WPP Group. Corbin J. Robertson, Jr. owns the general partner of Western Pocahontas 
Properties, 85% of the general partner of Great Northern Properties Limited Partnership and is the Chairman and Chief Executive 
Officer of New Gauley Coal Corporation.

Omnibus Agreement

As part of the omnibus agreement entered into concurrently with the closing of our initial public offering, the WPP Group 
and any entity controlled by Corbin J. Robertson, Jr., which we refer to in this section as the “GP affiliates,” each agreed that 
neither they nor their affiliates will, directly or indirectly, engage or invest in entities that engage in the following activities (each, 
a "restricted business") in the specific circumstances described below:

• 

• 

the entering into or holding of leases with a party other than an affiliate of the GP affiliate for any GP affiliate-owned 
fee coal reserves within the United States; and

the entering into or holding of subleases with a party other than an affiliate of the GP affiliate for coal reserves within 
the United States controlled by a paid-up lease owned by any GP affiliate or its affiliate.

"Affiliate" means, with respect to any GP affiliate or, any other entity in which such GP affiliate owns, through one or more 
intermediaries, 50% or more of the then outstanding voting securities or other ownership interests of such entity. Except as described 
below, the WPP Group and their respective controlled affiliates will not be prohibited from engaging in activities in which they 
compete directly with us.

A GP affiliate may, directly or indirectly, engage in a restricted business if:

• 

• 

• 

the GP affiliate was engaged in the restricted business at the closing of the offering; provided that if the fair market value 
of the asset or group of related assets of the restricted business subsequently exceeds $10 million, the GP affiliate must 
offer the restricted business to us under the offer procedures described below.

the asset or group of related assets of the restricted business have a fair market value of $10 million or less; provided 
that if the fair market value of the assets of the restricted business subsequently exceeds $10 million, the GP affiliate 
must offer the restricted business to us under the offer procedures described below.

the asset or group of related assets of the restricted business have a fair market value of more than $10 million and the 
general partner (with the approval of the conflicts committee) has elected not to cause us to purchase these assets under 
the procedures described below.

132

• 

its ownership in the restricted business consists solely of a non-controlling equity interest.

For purposes of this paragraph, "fair market value" means the fair market value as determined in good faith by the relevant 

GP affiliate.

The total fair market value in the good faith opinion of the WPP Group of all restricted businesses engaged in by the WPP 
Group, other than those engaged in by the WPP Group at closing of our initial public offering, may not exceed $75 million. For 
purposes of this restriction, the fair market value of any entity engaging in a restricted business purchased by the WPP Group will 
be determined based on the fair market value of the entity as a whole, without regard for any lesser ownership interest to be 
acquired.

If the WPP Group desires to acquire a restricted business or an entity that engages in a restricted business with a fair market 
value in excess of $10 million and the restricted business constitutes greater than 50% of the value of the business to be acquired, 
then the WPP Group must first offer us the opportunity to purchase the restricted business. If the WPP Group desires to acquire a 
restricted business or an entity that engages in a restricted business with a value in excess of $10 million and the restricted business 
constitutes 50% or less of the value of the business to be acquired, then the GP affiliate may purchase the restricted business first 
and then offer us the opportunity to purchase the restricted business within six months of acquisition. For purposes of this paragraph, 
"restricted business" excludes a general partner interest or managing member interest, which is addressed in a separate restriction 
summarized below. For purposes of this paragraph only, "fair market value" means the fair market value as determined in good 
faith by the relevant GP affiliate.

If we want to purchase the restricted business and the GP affiliate and the general partner, with the approval of the conflicts 
committee, agree on the fair market value and other terms of the offer within 60 days after the general partner receives the offer 
from the GP affiliate, we will purchase the restricted business as soon as commercially practicable. If the GP affiliate and the 
general partner, with the approval of the conflicts committee, are unable to agree in good faith on the fair market value and other 
terms of the offer within 60 days after the general partner receives the offer, then the GP affiliate may sell the restricted business 
to a third party within two years for no less than the purchase price and on terms no less favorable to the GP affiliate than last 
offered by us. During this two-year period, the GP affiliate may operate the restricted business in competition with us, subject to 
the restriction on total fair market value of restricted businesses owned in the case of the WPP Group.

If, at the end of the two year period, the restricted business has not been sold to a third party and the restricted business 
retains a value, in the good faith opinion of the relevant GP affiliate, in excess of $10 million, then the GP affiliate must reoffer 
the restricted business to the general partner. If the GP affiliate and the general partner, with the approval of the conflicts committee, 
agree on the fair market value and other terms of the offer within 60 days after the general partner receives the second offer from 
the GP affiliate, we will purchase the restricted business as soon as commercially practicable. If the GP Affiliate and the general 
partner, with the concurrence of the conflicts committee, again fail to agree after negotiation in good faith on the fair market value 
of the restricted business, then the GP affiliate will be under no further obligation to us with respect to the restricted business, 
subject to the restriction on total fair market value of restricted businesses owned.

In addition, if during the two-year period described above, a change occurs in the restricted business that, in the good faith 
opinion of the GP affiliate, affects the fair market value of the restricted business by more than 10 percent and the fair market value 
of the restricted business remains, in the good faith opinion of the relevant GP affiliate, in excess of $10 million, the GP affiliate 
will be obligated to reoffer the restricted business to the general partner at the new fair market value, and the offer procedures 
described above will recommence.

If the restricted business to be acquired is in the form of a general partner interest in a publicly held partnership or a managing 
member interest in a publicly held limited liability company, the WPP Group may not acquire such restricted business even if we 
decline to purchase the restricted business. If the restricted business to be acquired is in the form of a general partner interest in a 
non-publicly held partnership or a managing member of a non-publicly held limited liability company, the WPP Group may acquire 
such restricted business subject to the restriction on total fair market value of restricted businesses owned and the offer procedures 
described above.

The omnibus agreement may be amended at any time by the general partner, with the concurrence of the conflicts committee. 
The respective obligations of the WPP Group under the omnibus agreement terminate when the WPP Group and its affiliates cease 
to participate in the control of the general partner.

Board Representation and Observation Rights Agreement

Effective on March 2, 2017 in connection with the closing of the issuance of the Preferred Units, pursuant to the Board 
Representation and Observation Rights Agreement, Blackstone appointed Jasvinder S. Khaira to serve on the Board of Directors 
of GP Natural Resource Partners LLC and also appointed one observer to attend meetings of the Board. Blackstone's rights to 
appoint a member of the Board and an observer will terminate at such time as Blackstone, together with their affiliates, no longer 
own at least 20% of the total number of Preferred Units issued on the closing date, together with all PIK Units that have been 
issued but not redeemed (the "Minimum Preferred Unit Threshold"). Following the time that Blackstone (and their affiliates) no 
longer own the Minimum Preferred Unit Threshold and until such time as GoldenTree (together with their affiliates) no longer 
own the Minimum Preferred Unit Threshold, GoldenTree shall have the one time option to appoint either one person to serve as 
a member of the Board or one person to serve as a Board observer. To the extent GoldenTree elects to appoint a Board member 
and later remove such Board member, GoldenTree may then elect to appoint a Board observer. For more information on the 
Preferred Units, including the rights of the holders thereof, see Note 3. Class A Convertible Preferred Units and Warrants in the 
Notes to Consolidated Financial Statements under Item 8 in this Annual Report on Form 10-K.

Transactions with Cline Group and Affiliates

On May 9, 2017, Adena Minerals, LLC (“Adena”), an affiliate of Christopher Cline (“Cline”) sold its 31% limited partner 
interest in our general partner to Great Northern Properties Limited Partnership and WPPLP (the “Adena Sale”). In connection 
with the Adena Sale, on May 9, 2017, the Investor Rights Agreement effective as of January 4, 2007 by and among Adena, NRP 
GP, GP LLC, and Robertson Coal Management (the “Investor Rights Agreement”) terminated pursuant to its terms. Also on May 
9, 2017, the Restricted Business Contribution Agreement effective as of January 4, 2007, by and among Christopher Cline, Foresight 
Reserves LP, Adena, NRP, NRP GP, and NRP (Operating) LLC (the “RBCA”) terminated pursuant to the terms thereof. In addition, 
the rights of Adena and its affiliates under the Partnership’s partnership agreement are no longer in effect as a result of the Adena 
Sale (other than customary rights to indemnification). The Investor Rights Agreement and RBCA are described below.

As a result of the Adena Sale, we no longer consider Cline or his affiliates, including Foresight Energy, affiliates of NRP. 

Restricted Business Contribution Agreement

Christopher Cline, Foresight Reserves LP and Adena (collectively, the "Cline Parties") and NRP entered into a Restricted 
Business Contribution Agreement in 2007. Pursuant to the terms of the Restricted Business Contribution Agreement, the Cline 
Parties and their affiliates were obligated to offer to NRP any business owned, operated or invested in by the Cline Parties, subject 
to certain exceptions, that either (a) owns, leases or invests in hard minerals or (b) owns, operates, leases or invests in transportation 
infrastructure relating to future mine developments by the Cline Parties in Illinois. In addition, we created an area of mutual interest 
(the "AMI") around certain of the properties that we have acquired from Cline affiliates. During the applicable term of the Restricted 
Business Contribution Agreement, the Cline Parties were obligated to contribute any coal reserves held or acquired by the Cline 
Parties or their affiliates within the AMI to us. In connection with the offer of mineral properties by the Cline Parties to NRP, the 
parties to the Restricted Business Contribution Agreement agreed to negotiate and agree upon an area of mutual interest around 
such minerals, which would supplement and become a part of the AMI. On May 9, 2017, Adena Minerals, LLC (“Adena”) sold 
its 31% limited partner interest in NRP (GP) LP (the Partnership’s general partner) (“NRP GP”) to Great Northern Properties 
Limited Partnership (“GNPLP”) and WPPLP (the “Adena Sale”).

For a summary of revenues that we have derived from the Cline relationship, including Foresight Energy LP, see "Item 8.  
"Item 8. Financial Statements and Supplementary Data—Note 15. Related Party Transactions—Cline Affiliates" elsewhere in this 
Annual Report on Form 10-K.

Investor Rights Agreement

NRP and certain affiliates and Adena executed an Investor Rights Agreement pursuant to which Adena was granted certain 
management rights. Specifically, Adena had the right to name two directors (one of which must be independent) to the Board of 
Directors of our managing general partner so long as Adena beneficially owned either 5% of our limited partnership interests or 
5% of our general partner’s limited partnership interests and so long as certain rights under our managing general partner’s LLC 
Agreement had not been exercised by Adena or Mr. Robertson. During 2017, Leo A. Vecellio and L.G. (Trey) Jackson III served 
as Adena’s  two  directors.  Mr.  Jackson  resigned  from  the  Board  in  connection  with  the Adena  Sale.  Mr. Vecellio,  who  is  an 

134

 
independent director, remains on the Board. Adena also had the right, pursuant to the terms of the Investor Rights Agreement, to 
withhold its consent to the sale or other disposition of any entity or assets contributed by Cline affiliates to NRP, and any such sale 
or disposition would have been void without Adena’s consent.

Quintana Capital Group GP, Ltd.

Corbin J. Robertson, Jr. is a principal in Quintana Capital Group GP, Ltd., which controls several private equity funds focused 
on  investments  in  the  energy  business.  NRP’s  Board  of  Directors  has  adopted  a  formal  conflicts  policy  that  establishes  the 
opportunities that will be pursued by NRP and those that will be pursued by Quintana Capital. The basic tenets of the policy are 
set forth below.

NRP’s business strategy has historically focused on:

•  The ownership of natural resource properties in North America, including, but not limited to coal, aggregates and industrial 
minerals,  and  oil  and  gas.  NRP  leases  these  properties  to  mining  or  operating  companies  that  mine  or  produce  the 
resources and pay NRP a royalty.

•  The ownership and operation of transportation, storage and related logistics activities related to extracted hard minerals.

The businesses and investments described in this paragraph are referred to as the "NRP Businesses."
NRP’s acquisition strategy also includes:

•  The ownership of non-operating working interests in oil and gas properties.

•  The ownership of non-controlling equity interests in companies involved in natural resource development and extraction.

•  The operation of construction aggregates mining and production businesses.

The businesses and investments described in this paragraph are referred to as the "Shared Businesses."

NRP’s business strategy does not, and is not expected to, include:

•  The ownership of equity interests in companies involved in the mining or extraction of coal.

• 

• 

Investments that do not generate "qualifying income" for a publicly traded partnership under U.S. tax regulations.

Investments outside of North America.

•  Midstream  or  refining  businesses  that  do  not  involve  hard  extracted  minerals,  including  the  gathering,  processing, 

fractionation, refining, storage or transportation of oil, natural gas or natural gas liquids.

The businesses and investments described in this paragraph are referred to as the "Non-NRP Businesses."

It is acknowledged that neither Quintana Capital nor Mr. Robertson will have any obligation to offer investments relating 
to Non-NRP Businesses to NRP, and that NRP will not have any obligation to refrain from pursuing a Non-NRP Business if there 
is a change in its business strategy.

For so long as Corbin Robertson, Jr. remains both an affiliate of Quintana Capital and an executive officer or director of 
NRP or an affiliate of its general partner, before making an investment in an NRP Business, Quintana Capital has agreed to adhere 
to the following procedures:

•  Quintana Capital will first offer such opportunity in its entirety to NRP. NRP may elect to pursue such investment wholly 

for its own account, to pursue the opportunity jointly with Quintana Capital or not to pursue such opportunity.

• 

If NRP elects not to pursue an NRP Business investment opportunity, Quintana Capital may pursue the investment for 
its own account on similar terms.

•  NRP will undertake to advise Quintana Capital of its decision regarding a potential investment opportunity within 10 

business days of the identification of such opportunity to the Conflicts Committee.

If the opportunity relates to the acquisition of a Shared Business, NRP and Quintana Capital will adhere to the following 

procedures:

135

• 

• 

If the opportunity is generated by individuals other than Mr. Robertson, the opportunity will belong to the entity for 
which those individuals are working.

If the opportunity is generated by Mr. Robertson and both NRP and Quintana Capital are interested in pursuing the 
opportunity, it is expected that the Conflicts Committee will work together with the relevant Limited Partner Advisory 
Committees for Quintana Capital to reach an equitable resolution of the conflict, which may involve investments by 
both parties.

In all cases above in which Mr. Robertson has a conflict of interest, investment decisions will be made on behalf of NRP by 
the Conflicts Committee and on behalf of Quintana Capital Group by the relevant Investment Committee, with Mr. Robertson 
abstaining.

A fund controlled by Quintana Capital owns an interest in Corsa Coal Corp, a coal mining company traded on the TSX 
Venture Exchange that is one of our lessees in Tennessee. Corbin J. Robertson, III, one of our directors, was Chairman of the Board 
of Corsa through May 10, 2017. In addition, in May 2017, a subsidiary of Alpha Natural Resources assigned two coal leases with 
us to Quinwood Coal Partners LP ("Quinwood"), an entity controlled by Mr. Robertson, III. In connection with this lease assignment, 
Quinwood forfeited the historical recoupable balance related to this property.

For  more  information  on  our  relationship  with  Corsa  Coal  and  Quinwood,  see  "Item  8.  Financial  Statements  and 

Supplementary Data—Note 15. Related Party Transactions—Quintana Capital Group GP, Ltd."

Office Building in Huntington, West Virginia

We lease an office building in Huntington, West Virginia from Western Pocahontas Properties Limited Partnership. The 

terms of the lease, including $0.6 million per year in lease payments, were approved by our conflicts committee.

Conflicts of Interest

Conflicts of interest exist and may arise in the future as a result of the relationships between our general partner and its 
affiliates (including the WPP Group) on the one hand, and our partnership and our limited partners, on the other hand. The directors 
and officers of GP Natural Resource Partners LLC have duties to manage GP Natural Resource Partners LLC and our general 
partner in a manner beneficial to its owners. At the same time, our general partner has a duty to manage our partnership in a manner 
beneficial to us and our unitholders. The Delaware Revised Uniform Limited Partnership Act, which we refer to as the Delaware 
Act, provides that Delaware limited partnerships may, in their partnership agreements, expand, restrict or eliminate the fiduciary 
duties otherwise owed by a general partner to limited partners and the partnership. Pursuant to these provisions, our partnership 
agreement contains various provisions modifying the fiduciary duties that would otherwise be owed by our general partner with 
contractual standards governing the duties of the general partner and the methods of resolving conflicts of interest. Our partnership 
agreement also specifically defines the remedies available to limited partners for actions taken that, without these defined liability 
standards, might constitute breaches of fiduciary duty under applicable Delaware law.

Whenever a conflict arises between our general partner or its affiliates, on the one hand, and our partnership or any other 
partner, on the other, our general partner will resolve that conflict. Our general partner may, but is not required to, seek the approval 
of the conflicts committee of the Board of Directors of our general partner of such resolution. The partnership agreement contains 
provisions that allow our general partner to take into account the interests of other parties in addition to our interests when resolving 
conflicts of interest.

Our general partner will not be in breach of its obligations under the partnership agreement or its duties to us or our unitholders 
if the resolution of the conflict is considered to be fair and reasonable to us. Any resolution is considered to be fair and reasonable 
to us if that resolution is:

• 

• 

• 

approved by the conflicts committee, although our general partner is not obligated to seek such approval and our general 
partner may adopt a resolution or course of action that has not received approval;

on terms no less favorable to us than those generally being provided to or available from unrelated third parties; or

fair to us, taking into account the totality of the relationships between the parties involved, including other transactions 
that may be particularly favorable or advantageous to us.

136

In  resolving  a  conflict,  our  general  partner,  including  its  conflicts  committee,  may,  unless  the  resolution  is  specifically 

provided for in the partnership agreement, consider:

• 

• 

• 

• 

the relative interests of any party to such conflict and the benefits and burdens relating to such interest;

any customary or accepted industry practices or historical dealings with a particular person or entity;

generally accepted accounting practices or principles; and

such additional factors it determines in its sole discretion to be relevant, reasonable or appropriate under the circumstances.

Blackstone has certain consent rights and board appointment and observation rights and may be deemed to be an affiliate 
of our general partner. In addition, GoldenTree has certain limited consent rights. In the exercise of these consent rights and board 
rights, conflicts of interest could arise between us on the one hand, and Blackstone or GoldenTree on the other hand.

Conflicts of interest could arise in the situations described below, among others.

Actions taken by our general partner may affect the amount of cash available for distribution to unitholders.

The amount of cash that is available for distribution to unitholders is affected by decisions of our general partner regarding 

such matters as:

• 

• 

• 

• 

• 

amount and timing of asset purchases and sales;

cash expenditures;

borrowings;

the issuance of additional common units; and

the creation, reduction or increase of reserves in any quarter.

In addition, borrowings by us and our affiliates do not constitute a breach of any duty owed by our general partner to the 

unitholders, including borrowings that have the purpose or effect of enabling our general partner to receive distributions.

For example, in the event we have not generated sufficient cash from our operations to pay the quarterly distribution on our 
common units, our partnership agreement permits us to borrow funds which may enable us to make this distribution on all outstanding 
common units.

The partnership agreement provides that we and our subsidiaries may borrow funds from our general partner and its affiliates. 

Our general partner and its affiliates may not borrow funds from us or our subsidiaries.

We do not have any officers or employees other than in our Construction Aggregates business. We rely on officers and employees 
of GP Natural Resource Partners LLC and its affiliates.

Excluding our Construction Aggregates business, we do not have any officers or employees and rely on officers and employees 
of GP Natural Resource Partners LLC and its affiliates. Affiliates of GP Natural Resource Partners LLC conduct businesses and 
activities of their own in which we have no economic interest. If these separate activities are significantly greater than our activities, 
there could be material competition for the time and effort of the officers and employees who provide services to our general 
partner. The officers of GP Natural Resource Partners LLC are not required to work full time on our affairs. Certain of these officers 
devote significant time to the affairs of the WPP Group or its affiliates and are compensated by these affiliates for the services 
rendered to them.

We reimburse our general partner and its affiliates for expenses.

We reimburse our general partner and its affiliates for costs incurred in managing and operating us, including costs incurred 
in rendering corporate staff and support services to us. The partnership agreement provides that our general partner determines 
the expenses that are allocable to us in any reasonable manner determined by our general partner in its sole discretion.

137

Our general partner intends to limit its liability regarding our obligations.

Our general partner intends to limit its liability under contractual arrangements so that the other party has recourse only to 
our assets, and not against our general partner or its assets. The partnership agreement provides that any action taken by our general 
partner to limit its liability or our liability is not a breach of our general partner’s fiduciary duties, even if we could have obtained 
more favorable terms without the limitation on liability.

Common unitholders have no right to enforce obligations of our general partner and its affiliates under agreements with us.

Any agreements between us on the one hand, and our general partner and its affiliates, on the other, do not grant to the 

unitholders, separate and apart from us, the right to enforce the obligations of our general partner and its affiliates in our favor.

Contracts between us, on the one hand, and our general partner and its affiliates, on the other, are not the result of arm’s-
length negotiations.

The partnership agreement allows our general partner to pay itself or its affiliates for any services rendered to us, provided 
these services are rendered on terms that are fair and reasonable. Our general partner may also enter into additional contractual 
arrangements with any of its affiliates on our behalf. Neither the partnership agreement nor any of the other agreements, contracts 
and arrangements between us, on the one hand, and our general partner and its affiliates, on the other, are the result of arm’s-length 
negotiations.

All of these transactions entered into after our initial public offerings are on terms that are fair and reasonable to us.

Our general partner and its affiliates have no obligation to permit us to use any facilities or assets of our general partner and 
its affiliates, except as may be provided in contracts entered into specifically dealing with that use. There is no obligation of our 
general partner or its affiliates to enter into any contracts of this kind.

We may not choose to retain separate counsel for ourselves or for the holders of common units.

The attorneys, independent auditors and others who have performed services for us in the past were retained by our general 
partner, its affiliates and us and have continued to be retained by our general partner, its affiliates and us. Attorneys, independent 
auditors and others who perform services for us are selected by our general partner or the conflicts committee and may also perform 
services for our general partner and its affiliates. We may retain separate counsel for ourselves or the holders of common units in 
the event of a conflict of interest arising between our general partner and its affiliates, on the one hand, and us or the holders of 
common units, on the other, depending on the nature of the conflict. We do not intend to do so in most cases. Delaware case law 
has not definitively established the limits on the ability of a partnership agreement to restrict such fiduciary duties.

Our general partner’s affiliates may compete with us.

The partnership agreement provides that our general partner is restricted from engaging in any business activities other than 
those incidental to its ownership of interests in us. Except as provided in our partnership agreement and the Omnibus Agreement, 
affiliates of our general partner will not be prohibited from engaging in activities in which they compete directly with us.

The Conflicts Committee Charter is available upon request.

Director Independence

For a discussion of the independence of the members of the Board of Directors of our managing general partner under 
applicable standards, see "Item 10. Directors and Executive Officers of the Managing General Partner and Corporate Governance
—Corporate Governance—Independence of Directors," which is incorporated by reference into this Item 13.

Review, Approval or Ratification of Transactions with Related Persons

If a conflict or potential conflict of interest arises between our general partner and its affiliates (including the WPP Group 
on the one hand, and our partnership and our limited partners, on the other hand, the resolution of any such conflict or potential 
conflict is addressed as described under "—Conflicts of Interest."

138

Pursuant to our Code of Business Conduct and Ethics, conflicts of interest are prohibited as a matter of policy, except under 
guidelines approved by the Board and as provided in the Omnibus Agreement and our partnership agreement. For the year ended 
December 31, 2017, there were no transactions where such guidelines were not followed.

Young LLP to audit our accounts and assist with tax work for fiscal 2017 and 2016. All of our audit, audit-related fees and tax

Audit and Non-Audit Services Pre-Approval Policy

I. Statement of Principles

Under the Sarbanes-Oxley Act of 2002 (the "Act"), the Audit Committee of the Board of Directors is responsible for the 
appointment, compensation and oversight of the work of the independent auditor. As part of this responsibility, the Audit Committee 
is required to pre-approve the audit and non-audit services performed by the independent auditor in order to assure that they do 
not impair the auditor’s independence from the Partnership. To implement these provisions of the Act, the SEC has issued rules 
specifying the types of services that an independent auditor may not provide to its audit client, as well as the audit committee’s 
administration of the engagement of the independent auditor. Accordingly, the Audit Committee has adopted, and the Board of 
Directors has ratified, this Audit and Non-Audit Services Pre-Approval Policy (the "Policy"), which sets forth the procedures and 
the conditions pursuant to which services proposed to be performed by the independent auditor may be pre-approved.

The SEC’s rules establish two different approaches to pre-approving services, which the SEC considers to be equally valid. 
Proposed services may either be pre-approved without consideration of specific case-by-case services by the Audit Committee 
("general  pre-approval")  or  require  the  specific  pre-approval  of  the  Audit  Committee  ("specific  pre-approval").  The  Audit 
Committee believes that the combination of these two approaches in this Policy will result in an effective and efficient procedure 
to pre-approve services performed by the independent auditor. As set forth in this Policy, unless a type of service has received 
general pre-approval, it will require specific pre-approval by the Audit Committee if it is to be provided by the independent auditor. 
Any proposed services exceeding pre-approved cost levels or budgeted amounts will also require specific pre-approval by the 
Audit Committee.

For both types of pre-approval, the Audit Committee will consider whether such services are consistent with the SEC’s rules 
on auditor independence. The Audit Committee will also consider whether the independent auditor is best positioned to provide 
the most effective and efficient service for reasons such as its familiarity with our business, employees, culture, accounting systems, 
risk profile and other factors, and whether the service might enhance the Partnership’s ability to manage or control risk or improve 
audit quality. All such factors will be considered as a whole, and no one factor will necessarily be determinative.

139

 
The Audit Committee is also mindful of the relationship between fees for audit and non-audit services in deciding whether 
to pre-approve any such services and may determine, for each fiscal year, the appropriate ratio between the total amount of fees 
for audit, audit-related and tax services.

The appendices to this Policy describe the audit, audit-related and tax services that have the general pre-approval of the 
Audit Committee. The term of any general pre-approval is 12 months from the date of pre-approval, unless the Audit Committee 
considers a different period and states otherwise. The Audit Committee will annually review and pre-approve the services that 
may  be  provided  by  the  independent  auditor  without  obtaining  specific  pre-approval  from  the Audit  Committee.  The Audit 
Committee will add or subtract to the list of general pre-approved services from time to time, based on subsequent determinations.

The purpose of this Policy is to set forth the procedures by which the Audit Committee intends to fulfill its responsibilities. 
It  does  not  delegate  the Audit  Committee’s  responsibilities  to  pre-approve  services  performed  by  the  independent  auditor  to 
management.

Ernst & Young LLP, our independent auditor has reviewed this Policy and believes that implementation of the policy will 

not adversely affect its independence.

II. Delegation

As provided in the Act and the SEC’s rules, the Audit Committee has delegated either type of pre-approval authority to 
Robert B. Karn III, the Chairman of the Audit Committee. Mr. Karn must report, for informational purposes only, any pre-approval 
decisions to the Audit Committee at its next scheduled meeting.

III. Audit Services

The annual Audit services engagement terms and fees will be subject to the specific pre-approval of the Audit Committee. 
Audit services include the annual financial statement audit (including required quarterly reviews), subsidiary audits and other 
procedures required to be performed by the independent auditor to be able to form an opinion on the Partnership’s consolidated 
financial statements. These other procedures include information systems and procedural reviews and testing performed in order 
to understand and place reliance on the systems of internal control, and consultations relating to the audit or quarterly review. 
Audit services also include the attestation engagement for the independent auditor’s report on management’s report on internal 
controls for financial reporting. The Audit Committee monitors the audit services engagement as necessary, but not less than on 
a quarterly basis, and approves, if necessary, any changes in terms, conditions and fees resulting from changes in audit scope, 
partnership structure or other items.

In addition to the annual audit services engagement approved by the Audit Committee, the Audit Committee may grant 
general pre-approval to other audit services, which are those services that only the independent auditor reasonably can provide. 
Other audit services may include statutory audits or financial audits for our subsidiaries or our affiliates and services associated 
with SEC registration statements, periodic reports and other documents filed with the SEC or other documents issued in connection 
with securities offerings.

IV. Audit-related Services

Audit-related services are assurance and related services that are reasonably related to the performance of the audit or review 
of the Partnership’s financial statements or that are traditionally performed by the independent auditor. Because the Audit Committee 
believes that the provision of audit-related services does not impair the independence of the auditor and is consistent with the 
SEC’s rules on auditor independence, the Audit Committee may grant general pre-approval to audit-related services. Audit-related 
services  include,  among  others,  due  diligence  services  pertaining  to  potential  business  acquisitions/dispositions;  accounting 
consultations related to accounting, financial reporting or disclosure matters not classified as "Audit Services"; assistance with 
understanding and implementing new accounting and financial reporting guidance from rulemaking authorities; financial audits 
of employee benefit plans; agreed-upon or expanded audit procedures related to accounting and/or billing records required to 
respond to or comply with financial, accounting or regulatory reporting matters; and assistance with internal control reporting 
requirements.

140

V. Tax Services

The Audit Committee believes that the independent auditor can provide tax services to the Partnership such as tax compliance, 
tax planning and tax advice without impairing the auditor’s independence, and the SEC has stated that the independent auditor 
may provide such services. Hence, the Audit Committee believes it may grant general pre-approval to those tax services that have 
historically been provided by the auditor, that the Audit Committee has reviewed and believes would not impair the independence 
of the auditor and that are consistent with the SEC’s rules on auditor independence. The Audit Committee will not permit the 
retention of the independent auditor in connection with a transaction initially recommended by the independent auditor, the sole 
business purpose of which may be tax avoidance and the tax treatment of which may not be supported in the Internal Revenue 
Code and related regulations. The Audit Committee will consult with the Chief Financial Officer or outside counsel to determine 
that the tax planning and reporting positions are consistent with this Policy.

VI. Pre-Approval Fee Levels or Budgeted Amounts

Pre-approval fee levels or budgeted amounts for all services to be provided by the independent auditor will be established 
annually by the Audit Committee. Any proposed services exceeding these levels or amounts will require specific pre-approval by 
the Audit  Committee. The Audit  Committee  is  mindful  of  the  overall  relationship  of  fees  for  audit  and  non-audit  services  in 
determining whether to pre-approve any such services. For each fiscal year, the Audit Committee may determine the appropriate 
ratio between the total amount of fees for audit, audit-related and tax services.

VII. Procedures

All requests or applications for services to be provided by the independent auditor that do not require specific approval by 
the Audit Committee will be submitted to the Chief Financial Officer and must include a detailed description of the services to be 
rendered. The Chief Financial Officer will determine whether such services are included within the list of services that have received 
the general pre-approval of the Audit Committee. The Audit Committee will be informed on a timely basis of any such services 
rendered by the independent auditor.

Requests or applications to provide services that require specific approval by the Audit Committee will be submitted to the 
Audit Committee by both the independent auditor and the Chief Financial Officer, and must include a joint statement as to whether, 
in their view, the request or application is consistent with the SEC’s rules on auditor independence.

MINE SAFETY DISCLOSURE

Our mining operations are subject to regulation by the Federal Mine Safety and Health Administration (“MSHA”) under 
the Federal Mine Safety and Health Act of 1977 (the “Mine Act”). We have disclosed below information regarding certain citations 
and orders issued by MSHA and related assessments and legal actions with respect to these mining operations.  In evaluating the 
below information regarding mine safety and health, investors should take into account factors such as: (i) the number of citations 
and orders will vary depending on the size of a mine; (ii) the number of citations issued will vary from inspector to inspector and 
mine to mine; and (iii) citations and orders can be contested and appealed, and in that process are often reduced in severity and 
amount, and are sometimes dismissed or vacated.  The tables below do not include any orders or citations issued to independent 
contractors at our mines.

Section 1503 of the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”) requires 
issuers to include in periodic reports filed with the Securities and Exchange Commission (“SEC”) certain information relating to 
citations and orders for violations of standards under the Mine Act.  The following tables disclose information required under the 
Dodd-Frank Act for the year ended December 31, 2017.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Managers and Members of
Ciner Wyoming LLC
Atlanta, Georgia

Opinion on the Financial Statements

We have audited the accompanying balance sheets of Ciner Wyoming LLC (“the Company”) as of December 31, 2017 and 2016, 
and the related statements of operations and comprehensive income, members’ equity, and cash flows for each of the three years 
in the period ended December 31, 2017 and the related notes (collectively referred to as the "financial statements"). In our opinion, 
the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2017 and 
2016, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2017, in 
conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on 
the Company’s financial statements based on our audits. We are a public accounting firm registered with the Public Company 
Accounting  Oversight  Board  (United  States)  (PCAOB)  and  are  required  to  be  independent  with  respect  to  the  Company  in 
accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission 
and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB and in accordance with auditing standards generally 
accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance 
about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not 
required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, 
we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an 
opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due 
to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, 
evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting 
principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial 
statements. We believe that our audits provide a reasonable basis for our opinion.

(A Majority Owned Subsidiary of Ciner Resources LP)

NOTES TO FINANCIAL STATEMENTS
AS OF DECEMBER 31, 2017 AND 2016 AND FOR THE YEARS ENDED DECEMBER 31, 2017, 2016, AND 2015 
(Dollars in thousands)

1.  Corporate Structure

A 51% membership interest in Ciner Wyoming LLC (the "Company," "we," "us," or "our") is owned by Ciner Resources 
LP ("CINR" or the "Partnership"). NRP Trona LLC, a wholly owned subsidiary of Natural Resource Partners LP ("NRP") 
owns a 49% membership interest in the Company.  CINR is a master limited partnership traded on the New York Stock 
Exchange and is currently owned approximately 75% by Ciner Wyoming Holding Co. ("CINWHCO") and approximately 
25% by the general public. CINWHCO is 100% owned by Ciner Resources Corporation ("CRC") which is 100% owned 
by Ciner Enterprises, Inc. ("CINE"). As of December 31, 2017, CINE was 100% owned by Akkan Enerji ve Madencilik 
Anonim  irketi ("Akkan"), which is 100% 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. As 
described in subsequent events footnote 15, effective February 22, 2018, Akkan transferred its 100% direct ownership in 
CINE to WE Soda Ltd., a UK company, which is 100% owned by KEW Soda ltd., a UK company, which is owned 100% 
by Akkan.

Completed sale transaction - On October 23, 2015, CINE acquired 100% of OCI Chemical Corporation in a stock 
purchase transaction from OCI Enterprises Inc. ("OCIE") (the "Transaction"). OCI Chemical Corporation was 
subsequently renamed Ciner Resources Corporation. CRC owns indirectly the Company through CINWHCOs 
approximately 75% ownership interest in CINR. As a result of the closing of the Transaction, OCIE no longer has any 
direct or indirect ownership interest in the Company.

In connection with the closing of the Transaction, CINE (as borrower), and CINWHCO and CRC (as guarantors), entered 
into a credit facility (as amended and restated or otherwise modified, the “Ciner Enterprises Credit Facility”), which is 
secured by certain assets, including the common units of CINR owned by CINWHCO. 

2. Nature of Operations and Summary of Significant Accounting Policies

Nature of Operations - The Company operations consists of the mining of trona ore, which, when processed, becomes 
soda ash.  All our soda ash processed is sold to various domestic and European customers, and to Ciner Ic ve Dis Ticaret 
Anonim Sirketi ("CIDT") and American Natural Soda Ash Corporation ("ANSAC") which are affiliates for export sales. 
All mining and processing activities take place in one facility located in Green River, Wyoming.

Reclassifications - To conform to the presentation as of December 31, 2017, we made a reclassification in the balance 
sheet as of December 31, 2016 to include $46,467 of “Accounts receivable - ANSAC”, $9,054 of “Accounts receivable - 
other affiliate” and $6,299 of “Due from affiliates, net” within “Accounts receivable -affiliates”.  This reclassification had 
no effect on “Total current assets” as of December 31, 2016. We also made a corresponding reclassification in the 
statements of cash flows for the years ended December 31, 2016 and 2015 to include changes within “Accounts 
receivable -affiliates” to include the $5,744 and $18,199 changes in “Accounts receivable - ANSAC”, the ($9,054) and $0 
changes in “Accounts receivable - other affiliate”, and the $6,026 and $7,163 changes in “Due from affiliates, net” to be 
included within “Accounts receivable -affiliates” among the changes in operating assets and liabilities. These 
reclassifications had no effect on net cash provided by operating activities for any period.

8

A summary of the significant accounting policies is as follows:

Basis of Presentation - The accompanying financial statements have been prepared in accordance with accounting 
principles generally accepted in the United States of America.

Use of Estimates - The preparation of financial statements, in accordance with accounting principles generally accepted in 
the United States of America, 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 financial statements, and the 
reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Revenue Recognition - We recognize revenue when the earnings process is complete, which is generally upon transfer of 
title. This transfer typically occurs upon shipment to the customer, which is normally free on board (“FOB”) terms or 
upon receipt by the customer. In all cases, we apply the following criteria in recognizing revenue: (1) persuasive evidence 
of an arrangement exists; (2) delivery has occurred; (3) the selling price is fixed, determinable or reasonably estimated 
sales price has been agreed with the customer; and (4) collectability is reasonably assured.  Customer rebates and 
discounts are accounted for as sales deductions. We record amounts billed for shipping and handling fees as revenue. 
Costs incurred for shipping and handling are recorded as costs of products sold. 

Freight Costs - The Company includes freight costs billed to customers for shipments administered by the Company in 
gross sales. The related freight costs along with cost of products sold are deducted from gross sales to determine gross 
profit.

Cash and Cash Equivalents - The Company considers all highly liquid investments purchased with an original maturity of 
three months or less to be cash equivalents.  Cash equivalents consist primarily of money market deposit accounts.

Accounts Receivable - Accounts receivable are carried at the original invoice amount less an estimate for doubtful 
receivables. We generally do not require collateral against outstanding accounts receivable. The allowance for doubtful 
accounts is based on specifically identified amounts that the Company believes to be uncollectible. An additional 
allowance is recorded based on certain percentages of aged receivables, which are determined based on management’s 
assessment of the general financial conditions affecting the Company's customer base. We determined that no allowance 
for doubtful accounts was required against receivables from affiliates as of December 31, 2017 and 2016. If actual 
collection experience changes, revisions to the allowance may be required. Accounts receivable are written off when 
deemed uncollectible. Recoveries of accounts receivable previously written off are recorded when received. During the 
years ended 2017, 2016 and 2015 there were no significant accounts receivable bad debt expenses, write-offs or 
recoveries.

Inventory - Inventory is carried at the lower of cost or market. Cost is determined using the first-in, first-out method for 
raw material and finished goods inventory and the weighted average cost method for stores inventory. Costs include raw 
materials, direct labor and manufacturing overhead. Market is based on current replacement cost for raw materials and net 
realizable value for stores inventory and finished goods.

•  Raw material inventory includes material, chemicals and natural resources being used in the mining and refining 
process.

•  Finished goods inventory is the finished product soda ash.

•  Stores inventory includes parts, materials and operating supplies which are typically consumed in the production of 
soda ash and currently available for future use. Inventory expected to be consumed within the year is classified as current 
assets and remainder is classified as non-current assets.

9

Property, Plant, and Equipment - Property, plant, and equipment are stated at cost less accumulated depreciation. 
Depreciation is computed over the estimated useful lives of depreciable assets, using the straight-line method. The 
estimated useful lives applied to depreciable assets are as follows:

Land improvements
Depletable land
Buildings and building improvements
Internal-use computer software
Machinery and equipment
Furniture and fixtures

Useful Lives
10 years
15-60 years
10-30 years
3-5 years
5-20 years
10 years

The Company's policy is to evaluate property, plant, and equipment for impairment whenever events or changes in 
circumstances indicate that its carrying amount may not be recoverable.  An indicator of potential impairment would 
include situations when the estimated future undiscounted cash flows are less than the carrying value. The amount of any 
impairment then recognized would be calculated as the difference between estimated fair value and the carrying value of 
the asset.

Derivative Instruments and Hedging Activities - The Company may enter into derivative contracts from time to time to 
manage exposure to the risk of exchange rate changes on its foreign currency transactions, the risk of changes in natural 
gas prices, and the risk of the variability in interest rates on borrowings. Gains and losses on derivative contracts are 
reported as a component of the underlying transactions. The Company follows hedge accounting for its hedging activities. 
All derivative instruments are recorded on the balance sheet at their fair values. The accounting for changes in the fair 
value of a derivative depends on the intended use of the derivative and the resulting designation. The Company designates 
its derivatives based upon criteria established for hedge accounting under generally accepted accounting principles. For a 
derivative designated as a fair value hedge, the gain or loss is recognized in earnings in the period of change together with 
the offsetting gain or loss on the hedged item attributed to the risk being hedged. For a derivative designated as a cash 
flow hedge, the effective portion of the derivative’s gain or loss is initially reported as a component of accumulated other 
comprehensive income (loss) and subsequently reclassified into earnings when the hedged exposure affects earnings. Any 
significant ineffective portion of the gain or loss is reported in earnings immediately. For derivatives not designated as 
hedges, the gain or loss is reported in earnings in the period of change. The Company's natural gas physical forward 
contracts are accounted for under the normal purchases and normal sales scope exception. 

The Company has entered into interest rate swap contracts, designed as cash flow hedges, to mitigate the exposure to 
possible increases in interest rates. These contracts will mature on July 18, 2018. These contracts had an aggregate 
notional value of $70,000 and $72,000 at December 31, 2017 and December 31, 2016, respectively. At December 31, 
2017, it was anticipated that approximately $2 of losses currently recorded in accumulated other comprehensive income 
(loss) will be reclassified into earnings within the next 12 months.

The Company has entered into natural gas forward contracts, designed as cash flow hedges, to mitigate volatility in the 
price of the natural gas the Company consumes. These contracts generally have various maturities through 2022. These 
contracts had an aggregate notional value of  $37,087 and $30,969 at December 31, 2017 and December 31, 2016, 
respectively.  At December 31, 2017, it was anticipated that $1,906 of losses currently recorded in accumulated other 
comprehensive income (loss) will be reclassified into earnings within the next 12 months.

Income Tax - The Company is organized as a pass-through entity for federal and most state income tax purposes. States 
that do assess taxes on the Company are de minimis.  As a result, the members are responsible for federal income taxes 
based on their respective share of taxable income. Net income for financial statement purposes may differ significantly 
from taxable income reportable to members as a result of differences between the tax bases and financial reporting bases 
of assets and liabilities and the taxable income allocation requirements under the membership agreement.

Reclamation Costs - The Company is obligated to return the land beneath its refinery and tailings ponds to its natural 
condition upon completion of operations and is required to return the land beneath its rail yard to its natural condition 
upon termination of the various lease agreements.  

The Company accounts for its land reclamation liability as an asset retirement obligation, which requires that obligations 
associated with the retirement of a tangible long-lived asset be recorded as a liability when those obligations are incurred, 
with the amount of the liability initially measured at fair value. Upon initially recognizing a liability for an asset 
retirement obligation, an entity must capitalize the cost by recognizing an increase in the carrying amount of the related 
long-lived asset. Over time, the liability is accreted to its present value each period, and the capitalized cost is depreciated 
over the estimated useful life of the related asset. Upon settlement of the liability, an entity either settles the obligation for 
its recorded amount or incurs a gain or loss upon settlement.  

The estimated original liability calculated in 1996 for the refinery and tailing ponds was calculated based on the estimated 
useful life of the mine, which was 80 years, and on external and internal estimates as to the cost to restore the land in the 
future and state regulatory requirements. In 2018, the mining reserve will be amortized over a remaining life of 60 years. 
During 2017, 2016 and 2015 the remaining life was 61 years, 67 years and 68 years, respectively. The liability was 
discounted using a weighted average credit-adjusted risk free rate of approximately 6% and is being accreted throughout 
the estimated life of the related assets to equal the total estimated costs with a corresponding charge being recorded to 
cost of products sold. 

During 2011, the Company constructed a rail yard to facilitate loading and switching of rail cars. The Company is 
required to restore the land on which the rail yard is constructed to its natural conditions. The original estimated liability 
for restoring the rail yard to its natural condition was calculated based on the land lease life of 30 years and on external 
and internal estimates as to the cost to restore the land in the future. The liability is discounted using a credit-adjusted 
risk-free rate of 4.25% and is being accreted throughout the estimated life of the related assets to equal the total estimated 
costs with a corresponding charge being recorded to cost of products sold.

Fair Value of Financial Instruments - The following methods and assumptions were used to estimate the fair values of 
each class of financial instruments:

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 long-term debt and 
derivative financial instruments are measured at their fair values with Level 2 inputs based on quoted market values for 
similar but not identical financial instruments.

Long-Term Debt - The carrying value of our long-term debt materially reflects the fair value of our long-term debt as 
rates are variable and its key terms are similar to indebtedness with similar amounts, durations and credit risks.

Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair 
value measurement. Fair value accounting requires that these financial assets and liabilities be classified into one of the 
following three categories:

•  Level 1-inputs to the valuation methodology are quoted prices (unadjusted) for an identical asset or liability in an active        

market.

•  Level 2-inputs to the valuation methodology include quoted prices for a similar asset or liability in an active market or 
model-derived valuations in which all significant inputs are observable for substantially the full term of the asset or 
liability.

•  Level 3-inputs to the valuation methodology are unobservable and significant to the fair value measurement of the asset 

or liability.

Subsequent Events - The Company has evaluated all subsequent events through March 1, 2018, the date the financial 
statements were available to be issued.

Recently Issued Accounting Standards - 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 Company 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 Company has completed its evaluation of the provisions of this ASU and does not expect our adoption of 
ASU 2014-09 to materially change the amount or timing of revenues recognized by us, nor expect it to materially affect 
our financial position. The majority of our revenues generated are recognized upon delivery and transfer of title to the 
product to our customers. The time at which delivery and transfer of title occurs, for the majority of our contracts with 
customers, is the point when the product leaves our facility, thereby rendering our performance obligation fulfilled. The 
FASB issued various amendments to ASU 2014-09, one of which includes allowing entities to elect to account for 
shipping and handling activities performed after the control of a good has been transferred to the customer as a fulfillment 
cost versus an obligation of a promised service. The Company expects to make this an accounting policy election upon 
adoption to account for shipping and handling activities as fulfillment costs, which is not expected to have a material 
impact on our financial statements. The Company adopted this ASU effective January 1, 2018, as permitted by the ASU, 
using the modified retrospective method.

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 

12

early adoption is permitted. The Company is evaluating the potential impact the adoption of ASU No. 2016-02 will have 
on its financial statements. 

In August 2017, FASB issued ASU 2017-12, Derivatives and Hedging — Targeted Improvements to Accounting for 
Hedging Activities. This ASU aims to improve the financial reporting of hedging relationships to better portray the 
economic results of an entity’s risk management activities in its financial statements. In addition, this ASU make certain 
targeted improvements to simplify the application of the existing hedge accounting guidance. This ASU is effective for us 
beginning in the first quarter of 2019, with early application permitted. The Company is evaluating the effect the standard 
will have on its consolidated financial statements.

Revenue Bonds

The Variable Rate Demand Revenue Bonds are held by CINWYLLC.  These revenue bonds require the Company to 
maintain standby letters of credit totaling $11,606 and $20,333 at December 31, 2017 and 2016, 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 December 31, 2017, the Company was in compliance with these debt covenants. 

Ciner Wyoming Credit Facility

On August 1, 2017, the Company entered into a Credit Agreement (“Ciner Wyoming Credit Facility”) with each of the 
lenders listed on the respective signature pages thereof and PNC Bank, National Association, as administrative agent, 
swing line lender and a Letter of Credit ("L/C")  issuer. The Ciner Wyoming Credit Facility replaces the former Credit 
Facility, dated as of July 18, 2013, by and among the Company, the lenders party thereto and Bank of America, N.A., as 
administrative agent, swing line lender and L/C issuer, as amended (the “Former Ciner Wyoming Credit Facility”), which 
was terminated on August 1, 2017 upon entry into the Ciner Wyoming Credit Facility. This arrangement was accounted 
for as a modification of debt in accordance with Accounting Standards Codification (“ASC”) 470-50.

The Ciner Wyoming Credit Facility is a $225,000 senior unsecured revolving 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 Company 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 $75,000, 
subject to the Company 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 
$20,000 for same-day swing line advances and a sublimit up to $40,000 for letters of credit.

The Ciner Wyoming Credit Facility contains various covenants and restrictive provisions that limit (subject to certain 
exceptions) the Company’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 the Company;

•  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 interest coverage ratio (as defined in the 
Ciner Wyoming Credit Facility) of not less than 3.00 to 1.00.

The Ciner Wyoming Credit Facility 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 the Company may have. Upon the 
occurrence and during the continuation of an event of default, subject to the terms and

15

conditions of the Ciner Wyoming Credit Facility, the administrative agent at the request of shall, or with the consent of 
the Required Lenders (as defined in the Ciner Wyoming Credit Facility) 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 CRC 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 the General Partner of CINR (or any entity that performs the functions of the 
general partner of CINR). In addition, a change of control would be triggered if CINR ceases to own at least 50.1% of the 
economic interests in the Company or cease to have the ability to elect a majority of the members of the Company's board 
of managers.

Loans under the Ciner Wyoming Credit Facility bear interest at the Company’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

•  Eurodollar Rate plus an applicable margin.

The unused portion of the Ciner Wyoming Credit Facility is subject to an unused line fee ranging from 0.225% to 0.300% 
per annum based on Ciner Wyoming’s then current leverage ratio.

 At December 31, 2017, Ciner Wyoming was in compliance with all financial covenants of the Ciner Wyoming Credit 
Facility.

Former Ciner Wyoming Credit Facility

At December 31, 2016, the Company had a $190,000 senior unsecured revolving credit facility, as amended on October 
30, 2014 and May 25, 2016 (as amended, the "Former Ciner Wyoming Credit Facility"), with a syndicate of lenders, 
which would mature in July 2018. The Former Ciner Wyoming Credit Facility provided for revolving loans to fund 
working capital requirements, capital expenditures, to consummate permitted acquisitions and for all other lawful 
Company purposes. The Former Ciner Wyoming Credit Facility had an accordion feature that allowed the Company to 
increase the available revolving borrowings under the facility by up to an additional $75,000, subject to the Company 
receiving increased commitments from existing lenders or new commitments from new lenders and the satisfaction of 
certain other conditions. In addition, the Former Ciner Wyoming Credit Facility included a sublimit up to $20,000 for 
same-day swing line advances and a sublimit up to $40,000 for letters of credit. The Company's obligations under the 
Former Ciner Wyoming Credit Facility are unsecured.

The Former Ciner Wyoming Credit Facility contained various covenants and restrictive provisions that limited (subject to 
certain exceptions) the Company'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 the Company;

•  merge or consolidate with another Company; and

• 

transfer, sell or otherwise dispose of assets.

16

The Former Ciner Wyoming Credit Facility also required quarterly maintenance of a leverage ratio (as defined in the 
Former Ciner Wyoming Credit Facility) of not more than 3.00 to 1.00 and a fixed charge coverage ratio (as defined in the 
Former Ciner Wyoming Credit Facility) of not less than 1.00 to 1.00.  The Former Ciner Wyoming Credit Facility also 
required that capital expenditures, as defined in the Former Ciner Wyoming Credit Facility, not exceed $50,000 in any 
fiscal year.

  In addition, the Former Ciner Wyoming Credit Facility contained events of default customary for transactions of this 

nature, including (i) failure to make payments required under the Former Ciner Wyoming Credit Facility, (ii) events of 
default resulting from failure to comply with covenants and financial ratios in the Former Ciner Wyoming Credit Facility, 
(iii) the occurrence of a change of control, (iv) the institution of insolvency or similar proceedings against the Company 
and (v) the occurrence of a default under any other material indebtedness the Company may have. Upon the occurrence 
and during the continuation of an event of default, subject to the terms and conditions of the Former Ciner Wyoming 
Credit Facility, the lenders may terminate all outstanding commitments under the Former Ciner Wyoming Credit Facility 
and may declare any outstanding principal of the Former Ciner Wyoming Credit Facility debt, together with accrued and 
unpaid interest, to be immediately due and payable.

Under the Former Ciner Wyoming Credit Facility, a change of control is triggered if CRC 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 the general partner of CINR (or any entity that performs the 
functions the general partner of CINR). In addition, a change of control would be triggered if CINR ceases to own at least 
50.1% of the economic interests in the Company or cease to have the ability to elect a majority of the members of the 
Company's board of managers.

The Company was in compliance with all terms under its long-term debt agreements as of December 31, 2016.

Loans under the Former Ciner Wyoming Credit Facility bore interest at the Company'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 Former Ciner Wyoming Credit Facility was subject to an unused line fee ranging from 0.275% 
to 0.350% per annum based on the Company's then current leverage ratio.

Ciner Enterprises Credit Agreement

In addition, there are restrictions in the Ciner Enterprises Credit Agreement that affect the Company. 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 the Company to:

•  make distributions on or redeem or repurchase equity interests, other than distributions to the Companies 
members;

incur or guarantee additional debt, other than debt incurred under the Ciner Wyoming Credit Facility, among 

• 
certain other types of permitted debt;

•  make certain investments and acquisitions, other than investments in the Company, in an amount not to 
exceed $10,000 per calendar year and other exceptions set forth therein;

incur certain liens or permit them to exist, other than, with respect to the Companies liens, an aggregate 

• 
amount outstanding at any time equal to $1,000;

17

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

•  merge or consolidate with another company; or

transfer, sell or otherwise dispose of assets, other than the Companies disposition of assets with a net book 

• 
value not to exceed $2,500, in any given year.

10. EMPLOYEE BENEFIT PLANS

The Company participates in various benefit plans offered and administered by CRC (administered by OCIE prior to the 
Transaction) and has allocated its portions of the annual costs related thereto. The specific plans are as follows:

Retirement Plans - Benefits provided under the Ciner Pension Plan for Salaried Employees and Ciner 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. The retirement plans had an accumulated benefit obligation of $57,370 and $61,487 at December 31, 2017 
and 2016, respectively. CRC's funding policy is to contribute an amount within the range of the minimum required and 
the maximum tax-deductible contribution. The Company's allocated portion of net periodic pension cost was $1,358, 
$2,015 and $7,731 for the years ended December 31, 2017, 2016 and 2015, respectively. The decrease in pension costs in 
2017 was driven by improved discount rates.

Savings Plan - The Ciner 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 Company makes contributions based upon 
specified percentages of employee contributions. The Plan was amended such that participants hired on or subsequent to 
May 1, 2001, will receive an additional contribution from the Company based on a percentage of the participant’s base 
pay. Contributions made by the Company for the years ended December 31, 2017, 2016 and 2015 were $3,735, $1,625 
and $2,582, respectively.  The increase in 2017 was primarily due to the incremental contributions that were not made in 
prior year's comparative period due to the acquisition of CRC from OCI and the accelerated payouts in 2015.

18

Postretirement Benefits - Most of the Company's employees are eligible for postretirement benefits other than pensions if 
they reach retirement age while still employed.

CRC accounts for postretirement benefits on an accrual basis over an employee’s period of service. The postretirement 
plan, excluding pensions, are not funded, and CRC has the right to modify or terminate the plan. The post-retirement 
benefits had a benefits obligation of $11,465 and $20,586 for the years ended December 31, 2017 and 2016, respectively. 
The decrease in the obligation as of December 31, 2017 compared to December 31, 2016 is due to the CRC amending its 
postretirement benefit plan to increase eligibility requirements at which participants may begin receiving benefits, 
implemented a subsidy rather than a premium for the benefit plan, and eliminating plan eligibility for individuals hired 
after December 31, 2016. The Company's allocated portion of postretirement (benefit) costs was $(2,823), $1,400 and 
$495 for the years ended December 31, 2017, 2016 and 2015, respectively.  The postretirement benefit for the Company 
in 2017 is due to the aforementioned changes made to the postretirement benefit plans during 2017.

12. COMMITMENTS AND CONTINGENCIES

The Company leases mineral rights from the U.S. Bureau of Land Management, the state of Wyoming, Rock Springs 
Royalty Corp., a wholly owned subsidiary of Anadarko Holding Company, and other private parties. All of these leases 
provide for royalties based upon production volume. The remaining leases provide for minimum lease payments as 
detailed in the table below. The Company has a perpetual right of first refusal with respect to these leases and intends to 
continue renewing the leases as has been its practice.

The Company entered into a 10 year rail yard switching and maintenance agreement with a third party, Watco 
Companies, LLC, on December 1, 2011. Under the agreement, Watco provides rail-switching services at the Company’s 
rail yard. The Company's rail yard is constructed on land leased by Watco from Rock Springs Grazing Association and 
Anadarko Land Corp; the Rock Springs Grazing Association land lease is renewable every 5 years for a total period of 
30 years, while the Anadarko Land Corp. lease is perpetual. The Company has an option agreement with Watco to assign 
these leases to the Company at any time during the land lease term.

The Company entered into two track lease agreements, collectively, not to exceed 10 years with Union Pacific Company 
for certain rail tracks used in connection with the rail yard.

As of December 31, 2017, the total minimum rental commitments under the Company’s various operating leases, 
including renewal periods are as follows:

CRC, on behalf of the Company, typically enters into operating lease contracts with various lessors for railcars to 
transport product to customer locations and warehouses. Railcar leases under these contractual commitments range for 
periods from 1 to 10 years. CRC's obligations related to these railcar leases are $12,086 in 2018, $11,137 in 2019, $8,481 
in 2020, $5,869 in 2021, $3,805 in 2022 and $6,161 in 2023 and thereafter. Total lease expense allocated to the Company 
was approximately $14,628, $14,476 and $12,415 for the years ended December 31, 2017, 2016 and 2015, respectively.  

Purchase Commitments - The Company has natural gas supply contracts to mitigate volatility in the price of natural gas. 
As of December 31, 2017, these contracts totaled $29,474 for the purchase of a portion of our gas requirements over 
approximately the next three years. The supply purchase agreements have specific commitments of $14,253 in 2018, 
$8,366 in 2019 and $6,855 in 2020. The Company has a separate contract that expires in 2021, for transportation of 
natural gas with an average annual cost of approximately $3,870 per year.

Legal and Environmental - From time to time the Company is party to various claims and legal proceedings related to its 
business. Although the outcome of these proceedings cannot be predicted with certainty, management does not currently 
expect any of the legal proceedings the Company is involved in to have a material effect on its business, financial 
condition and results of operations. The Company 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 - The Company has a self-bond agreement with the Wyoming Department of 
Environmental Quality under which it commits to pay directly for reclamation costs at our Wyoming Plant site. As of 
December 31, 2017 and 2016, the amount of the bond was $32,900 and $38,200, respectively, which is the amount we 

20

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.

13. AFFILIATES TRANSACTIONS

CRC is the exclusive sales agent for the Company and through its membership in ANSAC, CRC is responsible for 
promoting and increasing the use and sale of soda ash and other refined or processed sodium products produced. ANSAC 
operates on a cooperative service-at-cost basis to its members such that typically any annual profit or loss is passed 
through to the members.  In the event an ANSAC member exits or the ANSAC cooperative is dissolved, the exiting 
members are obligated for their respective portion of the residual net assets or deficit of the cooperative. All actual sales 
and marketing costs incurred by CRC are charged directly to the Company. Selling, general and administrative expenses 
also include amounts charged to the Company by CRC principally consisting of salaries, benefits, office supplies, 
professional fees, travel, rent and other costs of certain assets used by the Company. On October 23, 2015 the Company 
entered into a Services Agreement (the “Services Agreement”) with CRC. Pursuant to the Services Agreement, CRC has 
agreed to provide the Company with certain corporate, selling, marketing, and general and administrative services, in 
return for which the Company has agreed to pay CRC an annual management fee and reimburse CRC for certain third-
party costs incurred in connection with providing such services. These transactions do not necessarily represent arm's 
length transactions and may not represent all costs if the Company operated on a standalone basis. In November 2016, 
CRC, on behalf of the Company, entered into a soda ash sales agreement with CIDT, an affiliate of Ciner Group, that sells 
soda ash to international 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 accounts 
receivable - affiliates line item on the balance sheet and interest earned is recorded in the interest income line item in the 
Statement of Operations and Comprehensive Income. CIDT is ultimately owned and controlled by the Ciner Group. 

As a result of the closing of the Transaction discussed in Note 1 - "Corporate Structure," CINE owns indirectly and 
controls the Company, therefore, OCIE and subsidiaries, including OCI Alabama LLC, are no longer related parties of the 
Company as of the Transaction date.  The following table includes transactions with OCIE and subsidiaries prior to the 
Transaction date.

The total costs (recoveries) charged to the Company by affiliates for the years ended December 31, 2017, 2016 and 2015 
are as follows:

(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 years ended December 31, 2017, 2016 and 
2015 these costs were $19,573, $3,278 and $8,134, respectively.  The increase in 2017 was driven by non-ANSAC export 
sales volume, primarily CIDT because the Company elects to use ANSAC to provide freight services for our other non-
ANSAC international sales, and ANSAC separately and directly charges the Company for such services.

14. MAJOR CUSTOMERS AND SEGMENT REPORTING

Our operations are similar in nature of products we provide and type of customers we serve. As the Company 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 for the years ended December 31, 2017, 
2016 and 2015 are as follows:
