Forward-Looking Statements

Statements included in this annual report may constitute forward-looking statements. In 

addition, we and our representatives may from time to time make other oral or written 

statements which are also forward-looking statements.

Such forward-looking statements include, among other things, statements regarding 

capital expenditures and acquisitions, expected commencement dates of mining, projected 

quantities of future production by our lessees producing from our reserves, and projected 

demand or supply for coal, trona and soda ash that will affect sales levels, prices and 

royalties realized by us.

These forward-looking statements speak only as of the date hereof and are made based 

upon management’s current plans, expectations, estimates, assumptions and beliefs 

concerning future events impacting us and therefore involve a number of risks and 

uncertainties. We caution that forward-looking statements are not guarantees and that 

actual results could differ materially from those expressed or implied in the forward-

looking statements.

You should not put undue reliance on any forward-looking statements. Please read “Item 

1A. Risk Factors” of the Form 10-K for important factors that could cause our actual results 

of operations or our actual financial condition to differ.

2018 Annual Report

To Our Unitholders

2018 was another transformative year for NRP. We saw continued stability 
in the coal markets, resulting in steady free cash flow generation. We also 
executed on key strategic initiatives, such as the sale of our construction 
aggregates business in December, which enabled us to accelerate the 
deleveraging of our balance sheet. We ended 2018 with strong liquidity, 
$206 million of cash and $100 million of credit facility borrowing capacity.

2018 Accomplishments Include:

• 

• 

• 

• 

• 

 Sale of VantaCore for $205 million, representing our exit from  
the construction aggregates business

 Favorable litigation settlement resulting in 2018 cash of $25 million

 Reduced debt by $141 million as of December 31, 2018 and  
$190 million as of January 15, 2019

 Lowered leverage (debt to EBITDA) from 2015 levels of 5.3x to 3.0x

 Continued quarterly common unit distributions of $0.45 per unit

“We saw continued stability in the coal 
markets, resulting in steady free cash 
flow generation. We also executed on key 
strategic initiatives, such as the sale of

2018 Annual Report

Business Highlights

Our Coal Royalty segment produced 83% of the partnership’s Revenue 
and other income and 82% of the partnership’s Free Cash Flow in 2018. 
This is primarily a result of solid metallurgical and thermal coal markets 
driven by strong export demand and steel industry fundamentals. 

Our soda ash business, of which we own a 49% equity interest, continues 
to perform and deliver cash distributions. We remain confident in Ciner 
Wyoming’s ability to produce some of the best quality and lowest cost 
natural soda ash over the long term.

Looking Forward

We remain committed to our goal of reducing debt, strengthening the 
balance sheet and maximizing the intrinsic value of the partnership.
In April 2019, we extended the maturity date of our $100 million revolving 
credit facility to 2023, and issued $300 million of 9.125% Senior Notes 
due 2025. We used the proceeds from this offering, together with cash on 
hand, to redeem all of our outstanding $346 million 10.500% Senior Notes 
due 2022, thus reducing further our total debt by $46 million. Looking 
ahead, we remain steadfast in our focus on de-levering and de-risking the 
partnership as we view this as the best way to create long-term value for 
our stakeholders. We thank you for your continued support of NRP and
we look forward to the opportunities ahead.

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

“We remain committed 
to our goal of reducing 
debt, strengthening 
the balance sheet and

ITEMS 1. AND 2.  BUSINESS AND PROPERTIES 

Partnership Structure and Management

We are a publicly traded Delaware limited partnership formed in 2002. We own, manage and lease a diversified portfolio of 

mineral properties in the United States, including interests in coal, soda ash from trona and other natural resources.

Our business is organized into two operating segments:

Coal Royalty and Other—consists primarily of coal royalty properties and coal-related transportation and processing assets. 
Other assets include industrial mineral royalty properties, aggregates royalty properties, oil and gas royalty properties and timber. 
Our coal reserves are primarily located in Appalachia, the Illinois Basin and in the Northern Powder River Basin in the 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 Ciner Wyoming, a trona ore mining operation and soda 
ash refinery, in the Green River Basin of Wyoming. Ciner Resources, LP, our operating partner, mines the trona, processes it into 
soda ash and distributes the soda ash both domestically and internationally to the glass and chemicals industries. 

In  December  2018,  we  sold  our  construction  aggregates  business  for  $205  million,  before  customary  purchase  price 
adjustments and transaction expenses, and recorded a gain of $13.1 million. Our exit from the construction aggregates business 
enabled us to further reduce debt, focus on our Coal Royalty and Other and Soda Ash business segments and represented a strategic 
shift as we exited the operations of our construction aggregates business. 

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 
GP Natural Resource Partners LLC and has delegated the right to appoint one director to Blackstone.

The  senior  executives  and  other  officers  who  manage  NRP  are  employees  of  Western  Pocahontas  Properties  Limited 
Partnership or Quintana Minerals Corporation, which are companies controlled by Mr. Robertson, Jr. These officers allocate varying 
percentages of their time to managing our operations. Neither our general partner, GP Natural Resource Partners LLC, nor any of 
their affiliates receive any management fee or other compensation in connection with the management of our business, but they 
are entitled to be reimbursed for all direct and indirect expenses incurred on our behalf.

We have regional offices through which we conduct our operations, the largest of which is located at 5260 Irwin Road, 
Huntington, West Virginia 25705 and the telephone number is (304) 522-5757. Our principal executive office is located at 1201 
Louisiana Street, Suite 3400, Houston, Texas 77002 and our telephone number is (713) 751-7507.

Our coal reserves are primarily located in the Appalachia Basin, the Illinois Basin and the Northern Powder River Basin in 
the United States. We lease our reserves to experienced mine operators under long-term leases. Approximately two-thirds of our 
royalty-based leases have initial terms of five to 40 years, with substantially all lessees having the option to extend the lease for 
additional terms. Leases include the right to renegotiate royalties and minimum payments for the additional terms. We also own 
and manage coal-related transportation and processing assets that generate additional revenues generally based on throughput or 
rents in the Illinois Basin. As described in the "—Other Coal Royalty and Other Segment Assets" section below, we also own oil 
and gas, aggregates and industrial mineral reserves that generate a portion of Coal Royalty and Other segment revenues. 

Under our standard royalty lease, we grant the operators the right to mine and sell our reserves in exchange for royalty 
payments based on the greater of a percentage of the sale price or fixed royalty per ton. 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 minimum payments, which reflect amounts we are 
entitled to receive even if no mining activity occurs during the period. Minimum payments are usually credited against future 
royalties that are earned as minerals are produced. In certain leases, the lessee is time limited on the period available for recouping 
minimum payments and such time is unlimited on other leases. 

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 costs, black lung benefits and workers’ compensation costs associated with operating 
the mines on our coal and aggregates properties. We pay property taxes on our properties, which are largely reimbursed by our 
lessees pursuant to the terms of the various lease agreements.

(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 or independent third party consultants. Significant internally generated reserve 
studies are reviewed by independent third party consultants. The technologies and economic data used 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, including loadout and other 
transportation assets at Foresight Energy's Williamson and Macoupin mines in the Illinois Basin, for which we collect throughput 
fees or rents. We lease our Macoupin and Williamson transportation and processing infrastructure to subsidiaries of Foresight 
Energy and are responsible for operating and maintaining the transportation and processing assets at the Williamson mine that we 
subcontract to a subsidiary of Foresight Energy. 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. The infrastructure at the Sugar Camp mine is leased to a 
subsidiary  of  Foresight  Energy  and  we  collect  throughput  fees.  We  recorded  $23.9  million  in  revenue  related  to  our  coal 
transportation and processing assets during the year ended December 31, 2018. 

Other Coal Royalty and Other Segment Assets 

As of December 31, 2018, we owned an estimated 173 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. The structure of these leases 
is similar to our coal leases, and these leases typically require minimum rental payments in addition to royalties. In addition, we 
hold overriding royalty interests in frac sand operations in Wisconsin and Texas and an overriding royalty interest in approximately 
82 million tons of sand and gravel reserves in Washington. During 2018, our lessees produced 4.3 million tons from these properties 
and we received $4.7 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 primarily in Louisiana, of which over 53,000 
acres were leased as of December 31, 2018; 

approximately 50 million tons of aggregates reserves primarily located in North Carolina, Arkansas and South Carolina 
and approximately 6 million tons of override royalty interest in South 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% (net) 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 owned by BRP remain largely undeveloped, BRP has an ongoing program 

to identify additional opportunities to lease its minerals to operating parties or otherwise monetize these assets.

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. 

15

The following map provides an aerial overview of Ciner Wyoming’s surface operations:

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 56 years.

16

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. 
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. Ciner Wyoming anticipates that its current deca stockpiles will be exhausted by 2023. In order to replace the volumes 
of soda ash produced from the deca rehydration process following exhaustion of those stockpiles, Ciner Wyoming will need to 
make significant capital expenditures over the next few years. See “Item 1A. Risk Factors—Risks Related to Our Business—We 
anticipate that Ciner Wyoming will need to increase capital expenditures in order to replace volumes of soda ash currently produced 
from the deca rehydration process, which could adversely affect Ciner Wyoming’s profitability and ability to make cash distributions 
to us.” 

Shipping and Logistics.  All of the soda ash produced is shipped by rail or truck from the Green River Basin facility. For the 
year ended December 31, 2018, Ciner Wyoming shipped approximately 93.5% of its soda ash to its customers initially via a single 
rail line owned and controlled by Union Pacific Railroad Company (“Union Pacific”). The Ciner Wyoming plant receives rail 
service exclusively from Union Pacific. The agreement with Union Pacific expires on December 31, 2019 and there can be no 
assurance that it will be renewed on terms favorable to Ciner Wyoming or at all. The rail freight rate charged under the agreement 
increases annually based on a published index tied to certain rail industry metrics. Ciner Resources Corporation 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")  currently  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 customers, including end users to whom ANSAC makes sales overseas, consist primarily of 
glass manufacturing companies, which account for 50% or more of the consumption of soda ash around the world; and chemical 
and detergent manufacturing companies. Ciner Wyoming’s largest customer currently is ANSAC, which buys soda ash (through 
Ciner Resources Corporation, which serves as Ciner Wyoming’s sales agent in its agreement with ANSAC) and other of its member 
companies for export to its customers. ANSAC accounted for approximately 52% of Ciner Wyoming’s net sales in 2018. 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, international sales were made through ANSAC as well as to affiliates 
of Ciner Resources Corporation.

In  November  2018,  Ciner  Resources  Corporation  delivered  a  notice  to  terminate  the  membership  in ANSAC,  which  is 
expected to be effective as of December 31, 2021. Until the effective termination date, ANSAC will continue to sell Ciner Wyoming’s 
soda ash to ANSAC-designated overseas territories and continue to provide logistics and support services for Ciner Wyoming’s 
other  export  sales. After  the  termination  period,  Ciner  Resources  Corporation  will  begin  marketing  soda  ash  directly  into 
international markets which are currently being served by ANSAC, and Ciner Wyoming intends to utilize the distribution network 
that has already been established by the global Ciner Group. The ANSAC agreement provides that 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. 

For customers in North America, Ciner Resources typically enters into contracts on Ciner Wyoming’s behalf with terms 
ranging from one to three years. Under these contracts, customers generally agree to purchase either minimum estimated volumes 
of soda ash or a certain percentage of their soda ash requirements at a fixed price for a given calendar year. Although Ciner Wyoming 
does not have a “take or pay” arrangements with its customers, substantially all sales are made pursuant to written agreements and 
not through spot sales. In 2018, Ciner Wyoming had more than 70 domestic customers and has had long-term relationships with 
the majority of its customers.

17

 
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.

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.

Significant Customers 

We have a significant concentration of revenues with Foresight Energy and its subsidiaries, with total revenues of $54.6 
million in 2018 from four different mining operations, including transportation and processing services, coal override and wheelage 
revenues. For additional information on significant customers, refer to "Item 8. Financial Statements and Supplementary Data—
Note 16. Major Customers."

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,  wind,  solar  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 
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.

Title to Property 

We owned substantially all of our coal and aggregates reserves in fee as of December 31, 2018. We lease the remainder from 
unaffiliated third parties. Ciner Wyoming 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.

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 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.

19

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 (CPP) 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 CPP 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 CPP Rule and issued an Advance Notice of Proposed Rulemaking soliciting information 
regarding a potential replacement rule to the CPP Rule. In August 2018, EPA formally proposed the Affordable Clean Energy 
(ACE) Rule, which would replace the CPP Rule. The ACE Rule contemplates a narrower approach than the CPP Rule, focusing 
on efficiency improvements at existing power plants and eliminating the CPP Rule’s broader goals that envisioned switches to 
non-fossil fuel energy sources and the implementation of efficiency measures on demand-side entities, which the EPA now considers 
beyond the reach of its authority under the Clean Air Act. The ACE Rule would also omit specific numerical emissions targets 
that had been established under the CPP 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.

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.

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 Ciner 
Wyoming's soda ash businesses.

20

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 Sixth Circuit lifted the nationwide stay. In February 2018, EPA and the Corps promulgated 
a rule delaying implementation of the 2015 WOTUS rule until 2020 and reinstating the regulatory definition of “Waters of the 
United States” that applied prior to the 2015 rule. Several federal district courts have enjoined the suspension rule, resulting in 
two different regulatory standards for determining the scope of jurisdiction under the Clean Water Act. Currently, the 2015 WOTUS 
rule is in effect in twenty-two states and Washington, D.C., while its predecessor remains in effect in the other twenty-eight. In 
December 2017, EPA and the Corps proposed a rule to repeal the WOTUS rule. In December 2018, EPA and the Corps issued a 
proposed  rule  revising  the  definition  of  “Waters  of  the  United  States.” 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 
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.

21

Other Regulations Affecting the Mining Industry

Mine Health and Safety Laws

The operations of our coal lessees 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 
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.

Employees and Labor Relations 

As of December 31, 2018, affiliates of our general partner employed 57 people who directly supported our operations. None 

of these employees were subject to a collective bargaining agreement.

ITEM 1A.  

RISK FACTORS 

Risks Related to Our Business 

Cash distributions are not guaranteed and may fluctuate with our performance and the establishment of financial reserves. In 
addition, our debt agreements and our partnership agreement place restrictions on our ability to pay, and in some cases raise, 
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  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 of $0.45 
per common unit per quarter. 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 "Item 7. 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, Net."

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

As of December 31, 2018, we and our subsidiaries had approximately $687.1 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, including higher interest rates. We are required to make substantial principal repayments each year 
in connection with Opco’s senior notes, with approximately $67 million due thereunder during 2019. In addition, Opco's revolving 
credit facility matures in April 2020. 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.

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 continue to be volatile and prices could decline substantially from current levels. Production by some of our 
lessees may not be economic if 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;

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

global and domestic demand for steel;

tariff rates on imports and trade disputes, particularly involving the United States and China;

the availability of, proximity to and capacity of transportation networks and 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, and renewable energy sources continue 
to gain market share in power generation. The abundance and ready availability of cheap natural gas, together with increased 
governmental regulations on the power generation industry has caused a number of utilities to switch from thermal coal to natural 
gas and/or close coal-powered generation plants. 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. Reduced international demand for export thermal coal, 
principally into India and northern Europe, has also put downward pressure on thermal coal prices.

25

Our lessees produce a significant amount of metallurgical coal that is used for steel production domestically and internationally. 
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 or 
increases in costs of the production from our properties may reduce our revenues. The level of production and costs thereof are 
subject to operating conditions or events beyond our or our lessees’ control including:

• 

• 

• 

difficulties or delays in acquiring necessary permits or mining or surface rights;

reclamation costs and bonding costs;

changes  or  variations  in  geologic  conditions,  such  as  the  thickness  of  the  mineral  deposits  and  the  amount  of  rock 
embedded in or overlying the mineral 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 networks and facilities and interruptions due to transportation delays;

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

labor-related interruptions and trained personnel shortages; and

•  mine safety incidents or accidents, including hazardous conditions, roof falls, fires and explosions.

While our lessees maintain insurance coverage, there is no assurance that insurance will be available or cover the costs of 
these  risks.  Many  of  our  lessees  are  experiencing  rising  costs  related  to  regulatory  compliance,  permitting  and  bonding, 
transportation, and labor. Increased costs result in decreased profitability for our lessees and reduce the competitiveness of coal 
as a fuel source. In addition, we and our lessees may also incur costs and liabilities resulting from third-party claims for damages 
to property or injury to persons arising from their operations. The occurrence of any of these events or conditions could have a 
material adverse effect on our business and results of operations.

The adoption of climate change legislation and regulations restricting emissions of greenhouse gases and other hazardous air 
pollutants have resulted in changes in fuel consumption patterns by electric power generators and a corresponding decrease 
in coal production by our lessees and reduced coal-related revenues.

Enactment of laws and passage of regulations regarding emissions from the combustion of coal by the U.S., some of its states 
or other countries, or other actions to limit such emissions, have resulted in and could continue to result in electricity generators 
switching from coal to other fuel sources and in coal-fueled power plant closures. Further, regulations regarding new coal-fueled 
power plants could adversely impact the global demand for coal. The potential financial impact on us of existing and future laws, 
regulations or other policies will depend upon the degree to which any such laws or regulations force electricity generators to 
diminish their reliance on coal as a fuel source. 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 Clean Power Plan and proposed rules promulgated by the EPA on greenhouse 
26

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 existing 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.  

In addition to EPA’s greenhouse gas 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. For more information on regulation of greenhouse gas and other 
air pollutant emissions, see "Items 1. and 2. Business and Properties—Regulation and Environmental Matters.”

Concerns about the environmental impacts of coal combustion, including perceived impacts on global climate issues, are also 
resulting in unfavorable lending and investment policies by institutions, which could significantly affect our ability to raise 
capital.

Global climate issues continue to attract public and scientific attention. Numerous reports have engendered concern about the 
impacts of human activity, especially fossil fuel combustion, on global climate issues. In addition to government regulation of 
greenhouse gas and other air pollutant emissions, there have also been efforts in recent years affecting the investment community, 
including  investment  advisors,  sovereign  wealth  funds,  public  pension  funds,  universities  and  other  groups,  promoting  the 
divestment of fossil fuel equities and also pressuring lenders to limit funding to companies engaged in the extraction of fossil fuels, 
such as coal. The impact of such efforts may adversely affect our ability to raise capital.

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 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. 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 mining 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.

27

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. 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.”

We derive a large percentage of our revenues and other income from a small number of coal lessees.

Challenges in the coal mining industry have led to significant consolidation activity. In 2018, Contura Energy and Alpha 
Natural Resources merged, and our revenues from the two companies on a combined basis accounted for approximately 17% of 
our total revenues in 2018. In addition, we own significant interests in all four of Foresight Energy’s mining operations, which 
accounted for approximately 22% of our total revenues in 2018. Certain other lessees have made acquisitions over the past few 
years resulting in their having an increased interest in our coal reserves. Any interruption in these lessees’ ability to make royalty 
payments to us could have a disproportionate material adverse effect on our business and results of operations.

Bankruptcies in the coal industry could have a material adverse effect on our business and results of operations.

Due to the continued challenges in the coal business, a number of coal producers filed for protection under U.S. bankruptcy 
laws during 2018, including several of our coal lessees. To the extent our leases are accepted or assigned, pre-petition amounts 
will be cured in full, but we may ultimately make concessions in the financial terms of those leases in order for the reorganized 
company or new lessor to operate profitably going forward. To the extent our leases are rejected, operations on those leases will 
cease,  and  we  will  be  unlikely  to  recover  the  full  amount  of  our  rejection  damages  claims.  More  of  our  lessees  may  file  for 
bankruptcy in the future, which will 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.

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 and timing of mining activities;

• 

processing and blending minerals;

28

• 

• 

• 

• 

• 

• 

• 

• 

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.

We are exposed to operating risks that we do not experience in the royalty business through our soda ash joint venture and 
through our ownership of certain coal transportation assets.

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, including increased maintenance and expansion capital expenditures that we may be 
required to fund, 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.

A significant portion of Ciner Wyoming’s historical international sales of soda ash have been to ANSAC, and the termination 
of the ANSAC membership could adversely affect Ciner Wyoming’s ability to compete in certain international markets and 
Ciner Wyoming’s ability to make cash distributions to us.

ANSAC has historically been Ciner Wyoming’s largest customer for the years ended December 31, 2018, 2017 and 2016, 
accounting for 52.0%, 44.7% and 55.2%, respectively, of its net sales. Following termination of the membership in ANSAC, which 
will be effective December 31, 2021, there is no assurance that Ciner Wyoming will be able to retain existing foreign customers 
or  secure  new  foreign  customers  or  the  related  logistics  arrangements  on  favorable  terms. Adverse  developments  in  Ciner 
Wyoming’s ability to transport soda ash and sell into the foreign markets currently served by ANSAC could result in lower cash 
distributions to us from Ciner Wyoming.

We anticipate that Ciner Wyoming will need to increase capital expenditures in order to replace volumes of soda ash currently 
produced from the deca rehydration process, which could adversely affect Ciner Wyoming’s profitability and ability to make 
distributions to us. 

Ciner Wyoming anticipates that its current deca stockpiles will be exhausted by 2023. In order to replace the volumes of 
soda ash produced from the deca rehydration process following exhaustion of those stockpiles, Ciner Wyoming will need to make 
significant capital expenditures over the next few years. There is no assurance that any such additional investments will be executed 
successfully or in a timely manner to enable Ciner Wyoming to maintain soda ash production levels.  In addition, if the capital for 
such investment projects cannot be obtained from alternative financing arrangements, Ciner Wyoming’s cash flows may decline, 
which could limit Ciner Wyoming’s ability to make cash distributions to us.

29

Fluctuations in transportation costs and the availability or reliability of transportation could reduce the production of coal, 
soda ash 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/or other events 
could temporarily impair the ability of our lessees to supply coal to their customers and/or increase their costs. Many of our lessees 
are currently experiencing transportation-related issues due in particular to decreased availability and reliability of rail services 
and port congestion. Our lessees’ transportation providers may face difficulties in the future that would 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. For the year ended December 31, 2018, Ciner Wyoming shipped approximately 93.5% of its soda ash from the Green 
River facility on a single rail line owned and controlled by Union Pacific. Ciner Wyoming’s current transportation contract with 
Union Pacific expires on December 31, 2019. There can be no assurance that this contract will be renewed on terms favorable to 
Ciner Wyoming or at all. 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.

Our business is subject to cybersecurity risks.

Our business is increasingly dependent on information technologies and services. Threats to information technology systems 
associated with cybersecurity risks and cyber incidents or attacks continue to grow. Although we utilize various procedures and 
controls to mitigate our exposure to such risks, cybersecurity attacks and other cyber events are evolving, unpredictable, and 
sometimes difficult to detect, and could lead to unauthorized access to sensitive information or render data or systems unusable.  

We do not presently maintain insurance coverage to protect against cybersecurity risks. If we procure such coverage in the 
future, we cannot ensure that it will be sufficient to cover any particular losses we may experience as a result of such cyber attacks. 
Any cyber incident could have a material adverse effect on our business, financial condition and results of operations.

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.

31

 
 
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.

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.

32

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

These conflicts may include the following:

•  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, 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.

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.

33

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 and current Treasury regulations, 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 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, the Treasury Department has issued, and in the future may issue, regulations interpreting those laws that affect 
publicly traded partnerships. Although there are no current legislative or administrative proposals, there can be no assurance that 
there will not be further changes to U.S. federal income tax laws or the Treasury Department’s interpretation of the qualifying 
income rules in a manner that could impact our ability to qualify as a publicly traded partnership in the future.  

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. You are urged 
to consult with your own tax advisor with respect to the status of regulatory or administrative developments and proposals and 
their potential effect on your 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 
income.

For our unitholders subject to the passive loss rules, our current operations include portfolio activities (such as our coal and 
mineral royalty businesses) and passive activities (such as our soda ash business). 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 royalty businesses, (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.

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.

35

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 these 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 and former 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. 

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. Distributions in excess of a common unitholder's allocable share of our net 
taxable income result in a decrease in the tax basis in such unitholder's common units. Accordingly, the amount, if any, of such 
prior excess distributions with respect to the common units sold 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. 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.

A substantial portion of the amount realized from a unitholder’s sale of our units, whether or not representing gain, may be 
taxed as ordinary income due to potential recapture items, including depletion and depreciation recapture. Thus, a unitholder may 
recognize both ordinary income and capital loss from the sale of units if the amount realized on a sale of such units is less than 
such unitholder’s adjusted basis in the units. Net capital loss may only offset capital gains and, in the case of individuals, up to 
$3,000 of ordinary income per year. In the taxable period in which a unitholder sells its units, such unitholder may recognize 
ordinary income from our allocations of income and gain to such unitholder prior to the sale and from recapture items that generally 
cannot be offset by any capital loss recognized upon the sale of units.  

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.

36

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, subject to the proposed 
aggregation rules for certain similarly situated businesses or activities issued by the Treasury Department, 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

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 
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 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, 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.

37

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 U.S. 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 and pay any taxes due in these jurisdictions. Unitholders should consult with their own tax advisors regarding the filing of 
such tax returns, the payment of such taxes, and the deductibility of any taxes paid.

ITEM 3.  LEGAL PROCEEDINGS 

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.

Foresight Energy Disputes

In October 2018, our lawsuits against Foresight Energy and its subsidiaries Hillsboro Energy and Macoupin Energy were 
settled. The Hillsboro suit was pending in the Circuit Court of the Fourth Judicial Circuit in Montgomery County, Illinois, and the 
Macoupin suit was pending in Macoupin County, Illinois. We received a payment of $25 million from Foresight Energy in full 
settlement of the Hillsboro litigation. In addition, we and Hillsboro Energy amended the coal mining lease with respect to the Deer 
Run  mine  to  change  the  $30  million  recoupable  annual  minimum  payments  to  $11  million  non-recoupable  annual  minimum 
payments effective January 1, 2019 and extended the current lease term through the end of 2033. Furthermore, Foresight Energy 
forfeited its recoupable balances under the Macoupin and Hillsboro leases totaling approximately $37.4 million. All claims were 
dismissed in both the Hillsboro and Macoupin lawsuits. 

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. The complaint alleged 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. We do not believe the reorganization transactions triggered an 
obligation to pay any additional contingent consideration and we are vigorously defending this lawsuit. However, the ultimate 
outcome cannot be predicted with certainty 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.

Distributable Cash Flow

Distributable cash flow ("DCF") represents net cash provided by (used in) operating activities of continuing operations plus 
distributions from unconsolidated investment in excess of cumulative earnings, proceeds from sales of assets, including sales of 
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 asses our ability to make cash 
distributions and repay debt. 

Free Cash Flow

Free  cash  flow  ("FCF")  represents  net  cash  provided  by  (used  in)  operating  activities  of  continuing  operations  plus 
distributions  from  unconsolidated  investment  in  excess  of  cumulative  earnings  and  return  of  long-term  contract  receivables 
(including affiliate); less maintenance and expansion capital expenditures, cash flow used in acquisition costs classified as financing 
activities and distributions to non-controlling interest. FCF is calculated before mandatory debt repayments. FCF 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. FCF may not be calculated the same for us as for other companies. FCF 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 our ability to make cash distributions and repay debt. 

The following table reconciles net cash provided by operating activities of continuing operations (the most comparable 

GAAP financial measure) to DCF and FCF for the years ended December 31, 2018, 2017, 2016, 2015, and 2014:

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, net income attributable to non-controlling interest and gain on reserve swap; plus 
total 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 "Item 8. Financial Statements and Supplementary Data—Note 13. Debt, Net" 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.

ITEM  7.    MANAGEMENT'S  DISCUSSION  AND  ANALYSIS  OF  FINANCIAL  CONDITION  AND  RESULTS  OF 
OPERATIONS

Introduction

The  following  discussion  and  analysis  presents  management’s  view  of  our  business,  financial  condition  and  overall 
performance and should be read in conjunction with our consolidated financial statements and footnotes included elsewhere in 
this filing. Our discussion and analysis consists of the following subjects:

•  Executive Overview

•  Results of Operations

•  Liquidity and Capital Resources

•  Off-Balance Sheet Transactions

•  Inflation

•  Environmental Regulation

•  Related Party Transactions

•  Summary of Critical Accounting Estimates

•  Recent Accounting Standards

As used in this Item 7, unless the context otherwise requires: "we," "our," "us" and the "Partnership" refer to Natural Resource 
Partners L.P. and, where the context requires, our subsidiaries. References to "NRP" and "Natural Resource Partners" refer to 
Natural Resource Partners L.P. only, and not to NRP (Operating) LLC or any of Natural Resource Partners L.P.’s subsidiaries. 
References  to  "Opco"  refer  to  NRP  (Operating)  LLC,  a  wholly  owned  subsidiary  of  NRP,  and  its  subsidiaries.  NRP  Finance 
Corporation ("NRP Finance") is a wholly owned subsidiary of NRP and a co-issuer with NRP on the 10.50% senior notes due 
2022 (the "2022 Notes").

Executive Overview 

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

Our business is organized into two operating segments:

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

In  December  2018,  we  sold  our  construction  aggregates  business  for  $205  million,  before  customary  purchase  price 
adjustments and transaction expenses, and recorded a gain of $13.1 million. Our exit from the construction aggregates business 
enabled us to further reduce debt, focus on our Coal Royalty and Other and Soda Ash business segments and represented a strategic 
shift as we exited the operations of our construction aggregates business. As a result, we have classified the assets and liabilities, 
operating results and cash flows of the construction aggregates business as discontinued operations in the consolidated financial 
statements for all periods presented. See "Item 8. Financial Statements and Supplementary Data—Note 4. Discontinued Operations" 
to the audited consolidated financial statements included elsewhere in this Annual Report on Form 10-K for additional information. 
Our debt agreements stipulated that 75% of the asset sale proceeds be used to pay down the Opco Revolving Credit Facility and 
25% be offered to the holders of the Opco Senior Notes on a pro-rata basis. The outstanding balance on the Opco Revolving Credit 
Facility was repaid in December 2018, $49 million was offered to the holders of the Opco Senior Notes in December 2018 and 
paid in January 2019, and we intend to use the remaining $55 million of net proceeds to repay the Opco Senior Notes as they 
amortize in 2019.

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.

Our 2018 financial results by business segment for the year ended December 31, 2018 are as follows:

Current Results/Market Commentary 

Coal Royalty and Other Business Segment 

Results in 2018 were driven by continued strength in both metallurgical and thermal coal markets. Metallurgical coal prices 
of all grades were driven higher from 2017 levels due to worldwide steel production growth along with a muted supply response 
from  metallurgical  coal  producers  due  to  various  constraints.  Benefiting  from  higher  metallurgical  coal  prices,  we  derived 
approximately 65% of our coal royalty revenues and approximately 55% of our coal royalty production from metallurgical coal 
during the year. Looking ahead into 2019, we expect metallurgical coal prices to remain relatively stable due to supportive steel 
industry fundamentals combined with logistical and operational supply constraints across the industry. Macro concerns including 
slowing GDP growth and trade issues could negatively impact the met market.

The domestic market for thermal coal has benefited from increased export demand from Asia, principally India, and northern 
Europe resulting in higher year over year prices in Central and Northern Appalachia, as well as the Illinois Basin. In addition, the 
domestic market benefited from higher natural gas prices that increased domestic thermal coal’s competitiveness. However, export 
thermal coal prices and domestic natural gas prices are currently down from the highs of 2018 and thermal coal pricing may be 
affected accordingly.

Soda Ash Business Segment

Ciner Wyoming's results are primarily affected by the global supply of and demand for soda ash, which in turn directly 
impacts the prices Ciner Wyoming and other producers charge for its products. Demand for soda ash in the United States is driven 
in a large part by economic growth and activity levels in the end-markets that the glass-making industry serve, such as the automotive 
and construction industries. Because the United States is a well-developed market for soda ash, we expect that domestic demand 
will remain stable for the near future. Because future United States capacity growth is expected to come from the four major 
producers in the Green River Basin, we also expect that U.S. supply levels will remain relatively stable in the near term. 

Soda ash demand in international markets has continued to grow in conjunction with GDP. We expect that future global 
economic growth will positively influence global demand, which will likely result in increased exports, primarily from the United 
States, Turkey and to a limited extent, from China, the largest suppliers of soda ash to international markets.

Total Coal Royalty and Other segment revenues and other income

$

(1)  These line items were impacted by the adoption of the new revenue recognition standard effective January 1, 2018. The total impact of 
the adoption of this standard in the year ended December 31, 2018 was a net decrease of $55.6 million in Coal Royalty and Other revenues. 
For more information on the overall impact of adoption of the new revenue recognition standard and changes to our revenue recognition 
policies as a result of this adoption, refer to "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. 

48

 
(2)  Production lease minimum revenue was $30.8 million in 2017 and included any expiration or forfeiture of minimums on all of our leases 
under ASC 605. Production lease minimum revenue was $8.2 million in 2018, including expired or forfeited minimums and breakage as 
a result of ASC 606. The $22.6 million decrease is primarily due to minimums expiring in 2018 that were included as breakage in the ASC 
606 cumulative effect entry to Partners’ capital on January 1, 2018, rather than to production lease minimum revenue. 

Coal Royalty Revenue

Coal royalty revenues increased $8.6 million from 2017 to 2018 primarily driven by the following:  

•  Appalachia: Coal royalty revenue increased $13.2 million as a result of higher metallurgical and thermal coal prices and 
higher  metallurgical  coal  production  as  a  result  of  increased  demand  primarily  in  Central  and  Northern Appalachia, 
partially offset by lower thermal coal production as a result of capital constraints and declining overall coal demand for 
certain of our lessees which limit their ability to increase production.

• 

Illinois Basin: A 37% decrease in production due to the temporary relocation of certain production off of NRP's coal 
reserves  more  than  offset  the  19%  increase  in  coal  royalty  price  per  ton  on  thermal  coal  and  resulted  in  a  $4.3 
million decrease in coal royalty revenue. The decrease in coal royalty revenue was partially offset by a $4.2 million 
increase in overriding royalty revenue and wheelage primarily associated with the production of non-NRP coal. 

Other Revenues

Total other revenues decreased $11.5 million from 2017 to 2018 primarily as a result of the impact of the new revenue 
recognition standard as discussed above. This decrease was partially offset by increased Coal overriding royalty revenue and 
Wheelage revenue from the production of non-NRP coal as described above in addition to the increased performance of our natural 
gas royalty properties. 

Transportation and Processing Services

Transportation and processing services revenue increased $3.4 million from 2017 to 2018 primarily driven by the increase 
in tons transported and processed using our assets at the Williamson and Sugar Camp mines and a higher per ton rate at the 
Macoupin mine.

Gain on Litigation Settlement

Gain on litigation settlement in the year ended December 31, 2018 related to a one-time payment of $25.0 million we received 

from Foresight Energy to settle the Hillsboro lawsuit.

Gain on Asset Sales, Net

Gain on asset sales, net for the segment decreased $1.1 million from 2017 to 2018. Gains on asset sales during the year ended 
December 31, 2018 primarily related to the sale of aggregates and other royalty properties and gains on asset sales during the year 
ended December 31, 2017 included sales of aggregates royalty properties and condemnation payments. 

Soda Ash

Revenues and other income related to our Soda Ash segment increased $7.8 million from 2017 to 2018 primarily as a result 
of Ciner Wyoming's litigation settlement of a royalty dispute that resulted in $12.7 million of income. This increase was partially 
offset by a $4.9 million decrease in income primarily due to lower production and sales resulting from unexpected equipment 
repairs needed, which were resolved during the second quarter of 2018, lower production volume in the third quarter of 2018 
primarily due to ore grade degradation, a decrease in international sales prices driven by the absence of international sales to Turkey 
and higher selling, general and administrative expenses related to ANSAC, higher employee compensation expense and higher 
fees related to Ciner Wyoming's Enterprise Resource Planning project. These decreases were partially offset by lower costs of 
products sold as a result of a decrease in freight costs driven by no export volumes to Turkey.

Total operating expenses increased by $16.2 million from 2017 to 2018. The primary reasons for this fluctuation are as 

follows: 

•  Operating and maintenance expenses include costs to manage the Coal Royalty and Other segment and primarily consist 
of taxes, royalty, employee related and legal costs. These costs increased $4.6 million primarily due to increased overriding 
royalty interest fees, legal costs and property taxes, partially offset by lower bad debt expense.

•  Depreciation, depletion and amortization ("DD&A") expense decreased $1.7 million primarily due to a $3.0 million 
decrease in depletion expense as a result of lower coal production in the Illinois Basin, partially offset by a $1.3 million 
increase on amortization of intangible assets. 

•  General and administrative ("G&A") expense decreased $2.0 million primarily due to lower employee-related costs year-

over-year.

•  Asset impairments increased $15.3 million. Asset impairments in the year ended December 31, 2018 primarily related 
to a $13.0 million impairment of an aggregates property that we own and lease to our former construction aggregates 
business, which mines, produces and sells the aggregates, in addition to $5.3 million of impairments related to certain of 
our coal properties. Asset impairments in the year ended December 31, 2017 primarily consisted of certain coal, aggregates 
and timber properties.

Total other expense, net decreased $23.9 million from 2017 to 2018. The primary reasons for this fluctuation are as follows: 

• 

Interest expense, net decreased $11.9 million primarily due to lower debt balances in 2018 as a result of repayments of 
debt.  

•  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 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 from Discontinued Operations 

Income from discontinued operations increased $11.5 million primarily as a result of the $13.1 million gain on sale of our 
construction aggregates business in the year ended December 31, 2018. This increase was partially offset by decreased net income 
from  the  operations  of  the  construction  aggregates  business  as  our  construction  aggregates  business'  $5.7  million  increase  in 
operating expenses more than offset its $3.1 million increase in revenues.

Adjusted EBITDA increased $18.8 million from 2017 to 2018. The primary reasons for this fluctuation are as follows: 

•  Coal Royalty and Other segment Adjusted EBITDA increased $19.2 million primarily as a result of the increase in revenues 
and other income as discussed above, partially offset by increased operating and maintenance expenses as discussed 
above. 

• 

Soda Ash segment Adjusted EBITDA decreased $2.5 million as a result of lower cash distributions received from Ciner 
Wyoming during the year ended December 31, 2018.

•  Corporate and financing Adjusted EBITDA increased $2.0 million as a result of the decrease in G&A costs as discussed 

above.

DCF and FCF increased $262.0 million and $62.1 million, respectively, from 2017 to 2018. The primary reasons for these 

fluctuations are as follows: 

•  Coal Royalty and Other segment DCF and FCF increased $47.6 million and $45.8 million, respectively, primarily due 
to  a  one-time  $25  million  payment  we  received  from  Foresight  Energy  to  settle  the  Hillsboro  lawsuit  in  addition  to 
increased cash from coal royalties as a result of higher metallurgical prices and production and increased cash from other 
revenues.

• 

Soda Ash segment DCF and FCF decreased $2.5 million as a result of lower cash distributions received from Ciner 
Wyoming during the year ended December 31, 2018.

•  Corporate and Financing DCF and FCF increased $18.8 million primarily as a result of lower performance-based award 

payments and lower cash paid for interest year-over-year.

Total DCF was also impacted by the $198.1 million proceeds from the sale of our construction aggregates business in the 

year ended December 31, 2018.

Coal Royalty Revenue

Coal royalty revenues increased $19.0 million from 2016 to 2017 primarily driven by the following:  

•  Appalachia: Coal royalty revenue increased $30.7 million as a result of increased metallurgical 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 as a result of the temporary relocation of certain production off 
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. 

Other Revenues

Total other revenues decreased $28.0 million 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 of 2016 and a $5.3 million decrease in property 
tax reimbursements. 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 and wheelage as 
discussed above. 

Transportation and Processing Services

Transportation and processing services revenue increased $1.2 million from 2016 to 2017 primarily driven by the increase 

in tons transported and processed using our assets at the Williamson mine. 

Gain on Asset Sales, Net

Gain on asset sales, net decreased $25.5 million from 2016 to 2017 primarily as a result of numerous asset sales completed 
during the year ended December 30, 2016, including an $18.6 million gain on the sale of oil and gas royalty and overriding royalty 
interests in the Appalachian Basin.

Total operating expenses decreased $28.3 million from 2016 to 2017. The primary reasons for these fluctuations are as 

follows: 

•  Operating and maintenance expenses decreased $5.0 million primarily due 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. 

•  DD&A expense decreased $8.4 million driven primarily by lower coal production in the Illinois Basin. 

•  G&A expense decreased $2.1 million 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 decreased $12.9 million. Asset impairments in the year ended December 31, 2017 primarily consisted 
of certain coal, aggregates and timber properties and asset impairments in the year ended December 31, 2016 primarily 
consisted of certain coal and aggregates properties. 

Total other expense, net increased $3.5 million from 2016 to 2017. The primary reasons for these fluctuations are as follows: 

• 

Interest  expense,  net  decreased $8.5  million  primarily  related  to  lower  debt  balances  during  2017  as  a  result  of  the 
recapitalization transactions entered into in March 2017.

•  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 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 from Discontinued Operations 

Income from discontinued operations was essentially flat from 2016 to 2017. Income related to our non-operated oil and gas 
working interest assets decreased $2.2 million as a result of the sale of these assets in July 2016 while income related to our 
construction aggregates business increased $2.1 million as a result of increased crushed stone, sand and gravel sales volumes year-
over-year.

Adjusted EBITDA decreased $23.8 million from 2016 to 2017. The primary reasons for these fluctuations are as follows: 

•  Coal Royalty and Other segment Adjusted EBITDA decreased $28.3 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, net.

• 

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

•  Corporate and financing Adjusted EBITDA increased $2.1 million primarily due to legal and consulting fees related to 

the recapitalization activities incurred in 2016.

DCF decreased $133.2 million from 2016 to 2017. This decrease is due primarily to the $109.9 million proceeds from the 

sale of our non-operated oil and gas working interest assets in 2016 in addition to the following:

•  Coal Royalty and Other segment DCF decreased $29.2 million primarily due to $61.0 million higher proceeds from asset 
sales in 2016 as compared to 2017, partially offset by a $31.6 increase in cash provided by operating activities as a result 
of improved performance of segment assets in 2017.

•  Corporate and Financing DCF increased $3.5 million primarily as a result of lower cash paid for interest and lower legal, 

consulting and advisory fees following the completion of the recapitalization transactions in March 2017.

• 

Soda Ash DCF increased $2.5 million as a result of higher cash distributions received from Ciner Wyoming in 2017.

FCF increased $45.4 million primarily as a result of the $31.6 million increase in cash provided by operating activities from 
the Coal Royalty and Other segment. FCF also increased as a result of the $7.2 million cash paid for acquisition costs in our Soda 
Ash segment in 2016, in addition to higher cash distributions received from Ciner Wyoming in 2017 and the $3.5 million increase 
in operating cash flows related to lower cash paid for interest and lower legal, consulting and advisory fees following the completion 
of the recapitalization transactions in March 2017.

Liquidity and Capital Resources

Current Liquidity 

As of December 31, 2018, we had total liquidity of $306.0 million, consisting of $101.8 million of cash and cash equivalents, 
$104.2 million of restricted cash and $100.0 million in borrowing capacity under our Opco Credit Facility. The $104.2 million of 
restricted cash represents the remaining net proceeds from the sale of our construction aggregates business that is required to be 
used to repay debt, make acquisitions or make capital expenditures per the terms of our debt agreements. In January 2019, we 
used approximately $49 million of this restricted cash to repay principal amounts on the Opco Senior Notes, and we intend to use 
the remaining $55 million to repay the Opco Senior Notes as they amortize in 2019. We remain focused on further reducing our 
debt and improving our liquidity metrics.

Cash Flows 

Cash flows provided by operating activities increased $61.8 million, from $127.1 million in the year ended December 31, 
2017 to $188.9 million in the year ended December 31, 2018 primarily related to increased operating cash flows in our Coal 
Royalty and Other segment as a result of a one-time $25 million payment we received from Foresight Energy to settle the Hillsboro 
lawsuit in addition to increased cash from coal royalties as a result of higher metallurgical prices and production and increased 
cash from other revenues. Also contributing to the increase in cash provided by operating activities was the decrease in G&A 
payments  primarily  as  a  result  of  the  payment  of  the  performance-based  awards  in  2017  following  the  completion  of  our 
recapitalization transactions in addition to lower cash paid for interest on our debt.

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 $31.9 
million primarily from increased operational performance from our Coal Royalty and Other segment assets year-over-year. This 
increase was partially offset by a $12.7 million decrease in operating cash flow from discontinued operations primarily due to cash 
flows from our non-operated oil and gas working interest assets prior to their sale in 2016.

Cash flow provided by investing activities increased $187.1 million, from $3.5 million in the year ended December 31, 2017 
to $190.6 million in the year ended December 31, 2018. Cash flows from discontinued operations increased $189.3 million as a 
result of the $198.1 million proceeds received from the sale of our construction aggregates business in December 2018, partially 
offset by increased construction aggregates capital expenditures during 2018. Cash flows from continuing operations decreased 
$2.2 million primarily due to a lower portion of our distribution from Ciner Wyoming classified as an investing activity in 2018. 

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 $108.0 
million primarily as a result of the $109.9 million proceeds received from the sale of our non-operated oil and gas working interest 
assets in the year ended December 31, 2016. Investing cash flows from continuing operations decreased $55.3 million primarily 
as a result of the proceeds received in 2016 from the sales of our oil and gas royalty and overriding royalty and aggregates royalty 
properties.

Cash flows used in financing activities increased $62.1 million, from $141.2 million in the year ended December 31, 2017 
to $203.3 million in the year ended December 31, 2018 primarily due to the proceeds received in 2017 related to recapitalization 
transactions, partially offset by the first quarter 2017 debt repayments and debt issuance costs paid as a result of the March 2017 
recapitalization transactions. Cash flow used in financing activities also increased as a result of the $21.4 million increase in 
preferred unit distributions and the $8.8 million redemption of the PIK units in the year ended December 31, 2018. 

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 in 2017. These proceeds were partially offset by additional 
debt repayments and debt issuance costs paid in the first quarter of 2017 as a result of the March 2017 recapitalization transactions.

Summary of Critical Accounting Policies

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 "Item 8. Financial Statements and Supplementary Data—Note 2. Summary of Significant Accounting 
Policies" in the audited consolidated financial statements 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 segment revenues

Royalty-based leases. In accordance with previous accounting standards in effect prior to January 1, 2018, we recognized 
all coal  and  aggregates royalty  revenue over  the  lease term  based  on  production. The recognition of  revenue  from  minimum 
payments was deferred until either recoupment through royalty production occurred or when the recoupment period expired for 
unrecouped  minimums.  Under  the  new  revenue  recognition  standard,  we  have  defined  our  coal  and  aggregates  royalty  lease 
performance obligation as providing the lessee the right to mine and sell our coal or aggregates over the lease term. We then 
evaluated  the  likelihood  that  consideration  we  expected  to  receive  from  our  lessees  resulting  from  production  would  exceed 
consideration expected to be received from minimum payments over the lease term. 

As a result of this evaluation, revenue recognition from our royalty-based leases is based on either production or minimum 

payments as follows: 

•  Production Leases: Leases for which we expect that consideration from production will be greater than consideration 
from minimums over the lease term. Revenue recognition for these leases is recognized over time based on production 
as Coal royalty revenue or Aggregates royalty revenue, as applicable. Deferred revenue from minimums is recognized 
as royalty revenue when recoupment occurs or as Production lease minimum revenue when the recoupment period 
expires. In addition, we recognize breakage revenue from minimums when we determine that recoupment is remote. 
This breakage revenue is included in Production lease minimum revenue.  

•  Minimum Leases: Leases for which we expect that consideration from minimums will be greater than consideration 
from production over the lease term. Revenue recognition for these leases is recognized straight-line over the lease 
term based on the minimum consideration amount as Minimum lease straight-line revenue. 

This evaluation is performed at the inception of the lease and only reassessed upon modification or renewal of the lease. 

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. We also have overriding royalty revenue interests 
in coal reserves. Revenue from these interests is recognized over time based on when the coal is sold. 

63

Wheelage.  Revenue related to fees collected per ton to transport foreign coal across property we own that is recognized over 

time as transportation across our property occurs. 

Other revenue.  Other revenue consists primarily of rental payments and surface damage fees related to certain land we own 
and is recognized straight-line over time as it is earned. Other revenues also include property tax revenues. The majority of property 
taxes  paid  on  our  properties  are  reimbursable by  the lessee  and  are  recognized  on  a  gross  basis  over  time  which  reflects the 
reimbursement of property taxes by the lessee. Property taxes we pay are included in Operating and maintenance expenses on our 
Consolidated Statements of Comprehensive Income.  

Transportation and processing services revenue.  We own transportation and processing infrastructure that is leased to third 
parties for throughput fees. Revenue is recognized over time based on the coal tons transported over the beltlines or processed 
through the facilities. 

Contract modifications

Contract modifications that impact goods or services or the transaction price are evaluated in accordance with ASC 606. A 
majority of our contract modifications pertain to our coal and aggregates royalty contracts and include, but are not limited to, 
extending the lease term, changes to royalty rates, floor prices or minimum consideration, assignment of the contract, forfeiture 
of  recoupment  rights  or  termination due  to  the  exhaustion  of  merchantable  and  mineable reserves.  Consideration  received in 
conjunction with a modification of an ongoing lease will be deferred and recognized straight-line over the remaining term of the 
contract. Consideration received to assign a lease to another party and related forfeited minimums will be recognized immediately 
upon the termination of the contract. Fees from contract modifications are recognized in Lease modification fees within Coal 
royalty and other revenues on our Consolidated Statements of Comprehensive Income while modifications in royalty rates and 
minimums will be recognized prospectively in accordance with the above lease classification.

In accordance with the transition guidance in paragraph 606-10-65-1, revenues from contracts that were modified before 
January  1,  2018  were  not  retrospectively  restated  for  those  modifications  and  instead  reflected  the  aggregate  effect  of  those 
modifications  when  identifying  the  satisfied  and  unsatisfied  performance  obligations,  determining  the  transaction  price  and 
allocating the transaction price to the satisfied and unsatisfied performance obligation. 

Contract Assets and Liabilities from Contracts with Customers

Contract assets include receivables from contracts with customers and are recorded when the right to consideration becomes 
unconditional. Receivables are recognized when the minimums are contractually owed, production occurs or minimums are accrued 
for based on the passage of time.

Contract liabilities represent minimum consideration received, contractually owed or earned based on the passage of time. 
The current portion of deferred revenue relates to deferred revenue on minimum leases and lease modification fees that are to be 
recognized as revenue on a straight-line basis over the next twelve months. The long-term portion of deferred revenue relates to 
deferred revenue on production leases and lease modification fees that are to be recognized as revenue on a straight-line basis 
beyond the next twelve months. Due to uncertainty in the amount of deferred revenue that will be recouped and recognized as 
Coal royalty revenue from production leases over the next twelve months, we are unable to estimate the current portion of deferred 
revenue. 

Equity in Earnings of Ciner Wyoming. 

We account 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. Our 49% investment in Ciner Wyoming is accounted for 
using this method.

64

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 attributed to net tangible assets and is amortized over its estimated useful life. The 
carrying value in Ciner Wyoming is recognized in Equity in unconsolidated investment in our Consolidated Balance Sheets. Our 
adjusted share of the earnings or losses of Ciner Wyoming and amortization of the basis difference is recognized in Equity in 
earnings  of  Ciner  Wyoming  in  the  Consolidated  Statements  of  Comprehensive  Income.  We  increase  our  investment  for  our 
proportional share of distributions received from Ciner Wyoming. These cash flows are reported utilizing the cumulative earnings 
approach. Under this approach, distributions received are considered returns on investment and classified as operating cash inflows 
unless the cumulative distributions received exceed our cumulative equity in earnings. The excess of cumulative distributions 
received over our cumulative equity in earnings are considered returns of investment and classified as investing cash inflows. 

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 aggregates 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 evaluate our long-lived assets for possible impairment periodically or whenever events 
or changes in circumstances indicate an asset's carrying amount may not be recoverable. Potential events or circumstances include, 
but are not limited to, specific events such as a reduction in economically recoverable reserves or production ceasing on a property 
for an extended period. 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.  

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"  in  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

Our  revenues,  operating  results,  financial  condition  and  ability  to  borrow  funds  or  obtain  additional  capital  depend 
substantially on prevailing commodity prices. Historically, coal prices have been volatile, with prices fluctuating widely, and they 

65

are likely to continue to be volatile. Depressed prices in the future would have a negative impact on our future financial results. 
In particular, substantially lower prices would significantly reduce revenue and could potentially trigger an impairment of our coal 
properties or a violation of certain financial debt covenants. Because substantially all of our reserves are coal, changes in coal 
prices have a more significant impact on our financial results.

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 future 
financial results. If more coal is sold on the spot market, coal royalty revenues may become more volatile due to fluctuations in 
spot coal prices.

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, 2018 we did not have any borrowings outstanding under the Opco 
Credit Facility. 

Fair Value of Financial Assets and Liabilities

Our financial assets and liabilities consist of cash and cash equivalents, restricted cash,  contracts receivable, debt, Preferred 
Units and Warrants. The carrying amounts reported on the Consolidated Balance Sheets for cash and cash equivalents and restricted 
cash 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:

(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.

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

assets.

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, 2018 and 2017, the related consolidated statements of comprehensive income, partners’ capital and cash flows for 
each of the three years in the period ended December 31, 2018, and the related notes (collectively referred to as the “consolidated 
financial statements”). In our opinion, based on our audits and the report of other auditors, the consolidated financial statements 
present fairly, in all material respects, the financial position of the Partnership at December 31, 2018 and 2017, and the results of 
its operations and its cash flows for each of the three years in the period ended December 31, 2018, 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 $247 million and $245 million as of December 31, 2018 and 2017, respectively, and the Partnership’s equity in the net income 
of Ciner Wyoming is stated at $48 million in 2018, $40 million in 2017 and $40 million in 2016. 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 solely 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, 2018, 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 7, 2019 expressed an unqualified opinion thereon.

Adoption of ASU No. 2014-09 

As discussed in Note 2 to the consolidated financial statements, the Partnership adopted ASU No. 2014-09, “Revenue from Contracts 
with Customers (Topic 606)” effective January 1, 2018. As a result, for the year ended December 31, 2018, the Partnership changed 
its method for revenue recognition related to royalty lease arrangements.  

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.

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, 2018 and 2017, 
and the related statements of operations and comprehensive income, members’ equity, and cash flows for each of the three years

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.

We have served as the Company’s auditor since 2008.

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, 
managing and leasing a diversified portfolio of mineral properties in the United States, including interests in coal, trona, soda ash 
and other natural resources and is organized into two operating segments further described in Note 8. 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 in Ciner Wyoming 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 Statements of Comprehensive Income and 
Consolidated Statements of Cash Flows to conform with current year presentation. These reclassifications have no impact on 
previously reported net income or total cash flows from operating, investing or financing activities.

Recasting of Certain Prior Period Information

As described in Note 4. Discontinued Operations, the Partnership has classified the assets and liabilities, operating results 
and cash flows of its construction aggregates business as discontinued operations in its consolidated financial statements for all 
periods presented. 

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 during the reporting period. Actual results 
could differ from those estimates. The most significant estimates pertain to coal and aggregates reserves and related cash flow 
estimates which are used to compute depreciation, depletion and amortization and impairments of coal and aggregates properties 
and commitments and contingencies. 

75

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 for further details.

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 assets and liabilities 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, Cash Equivalents and Restricted Cash

The Partnership considers all highly liquid short-term investments with an original maturity of three months or less to be 
cash  equivalents.  Restricted  cash  at  December  31,  2018  included  cash  proceeds  received  from  the  sale  of  the  Partnership's 
construction aggregates business required to be used to repay debt, make acquisitions or make capital expenditures per the terms 
of its and Opco's debt agreements, as defined in Note 13. Debt, Net. NRP intends to use these proceeds to repay debt. 

Allowance for Doubtful Accounts

The  Partnership  records  an  allowance  for  doubtful  accounts  for  its  accounts  receivables  and  notes  receivables  which  it 
determines to be uncollectible based on the specific identification method. Receivables are written off when collection efforts are 
exhausted and future recovery is doubtful. The allowance for doubtful accounts receivable is included in Accounts receivable, net 
and the allowance for doubtful accounts for notes receivable is included in Other current assets on the Partnership's Consolidated 
Balance Sheets, respectively. The allowance for doubtful accounts related to accounts receivable was $4.8 million at December 31, 
2017. The allowance for doubtful accounts related to notes receivable included in Other current assets was $1.2 million at both 
December 31, 2018 and 2017, respectively. The Partnership recorded bad debt expense of $0.1 million, $2.4 million and $0.3 
million, respectively, included in Operating and maintenance expense (including affiliates) on its Consolidated Statements of 
Comprehensive Income for the years ended December 31, 2018, 2017 and 2016, respectively.  

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 aggregates transportation and processing 
infrastructure. Expenditures for new facilities or that substantially increase the useful life of property are capitalized and reported 
in the Consolidated Statements of Cash Flows as an investing activity. These assets are depreciated on a straight-line basis over 
their useful lives generally as follows: 

Buildings and improvements
Machinery and equipment
Leasehold improvements

Mineral Rights

Years
20 to 40
5 to 12
Life of Lease

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 aggregates 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. Management expects for the above-market rates to be received 
until the reserves are exhausted on its above-market contracts, which includes additional renewal terms of the respective leases. 
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.

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. Potential events or circumstances 
include, but are not limited to, specific events such as a reduction in economically recoverable reserves or production ceasing on 
a property for an extended period. This analysis is based on historic, current and future performance and 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. The Partnership 
believes its estimates of cash flows and discount rates are consistent with those of principal market participants. 

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 (Level 1), or upon the present value of expected cash flows using discount rates believed to be consistent 
with those used by principal market participants (Level 3), plus market analysis of comparable assets owned by the investee, if 
appropriate.

Revenue Recognition

Coal Royalty and Other Segment Revenues

Royalty-based leases. Approximately two-thirds of the Partnership's royalty-based leases have initial terms of five to 40
years, with substantially all lessees having the option to extend the lease for additional terms. For these types of leases, the lessees 
generally make payments to NRP based on the greater of a percentage of the gross sales price or a fixed price per ton of mineral 
they mine or sell. Most of NRP’s coal and aggregates royalty leases require the lessee to pay quarterly or annual minimum amounts, 
either made in advance or arrears, which are generally recoupable through actual royalty production over certain time periods that 
generally range from three to five years. 

In accordance with previous accounting standards in effect prior to January 1, 2018, NRP recognized all coal and aggregates 
royalty revenue over the lease term based on production. The recognition of revenue from minimum payments was deferred until 
either recoupment through royalty production occurred or when the recoupment period expired for unrecouped minimums. 

Under the new revenue recognition standard, management has defined NRP's coal and aggregates royalty lease performance 
obligation as providing the lessee the right to mine and sell NRP's coal or aggregates over the lease term. The Partnership then 
evaluated the likelihood that consideration NRP expected to receive from its lessees resulting from production would exceed 
consideration expected to be received from minimum payments over the lease term. 

77

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

As a result of this evaluation, revenue recognition from the Partnership's royalty-based leases is based on either production 

or minimum payments as follows: 

•  Production Leases: Leases for which the Partnership expects that consideration from production will be greater than 
consideration from minimums over the lease term. Revenue recognition for these leases is recognized over time based 
on production as Coal royalty revenue or Aggregates royalty revenue, as applicable. Deferred revenue from minimums 
is recognized as royalty revenue when recoupment occurs or as Production lease minimum revenue when the recoupment 
period expires. In addition, NRP recognizes breakage revenue from minimums when NRP determines that recoupment 
is remote. This breakage revenue is included in Production lease minimum revenue.  

•  Minimum Leases: Leases for which the Partnership expects that consideration from minimums will be greater than 
consideration from production over the lease term. Revenue recognition for these leases is recognized straight-line over 
the lease term based on the minimum consideration amount as Minimum lease straight-line revenue. 

This evaluation is performed at the inception of the lease and only reassessed upon modification or renewal of the lease.

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. The Partnership also has overriding royalty 
revenue interests in coal reserves. Revenue from these interests is recognized over time based on when the coal is sold. 

Wheelage.  Revenue related to fees collected per ton to transport foreign coal across property owned by the Partnership that 

is recognized over time as transportation across the property occurs. 

Other revenue.  Other revenue consists primarily of rental payments and surface damage fees related to certain land owned 
by the Partnership and is recognized straight-line over time as it is earned. Other revenues also include property tax revenues. The 
majority of property taxes paid on the Partnership's properties are reimbursable by the lessee and are recognized on a gross basis 
over time which reflects the reimbursement of property taxes by the lessee. Property taxes paid by NRP are included in Operating 
and maintenance expenses on the Partnership's Consolidated Statements of Comprehensive Income.  

Transportation and processing services revenue.  The Partnership owns transportation and processing infrastructure that is 
leased to third parties for throughput fees. Revenue is recognized over time based on the coal tons transported over the beltlines 
or processed through the facilities. 

Contract modifications

Contract modifications that impact goods or services or the transaction price are evaluated in accordance with ASC 606. A majority 
of the Partnership's contract modifications pertain to its coal and aggregates royalty contracts and include, but are not limited to, 
extending the lease term, changes to royalty rates, floor prices or minimum consideration, assignment of the contract, forfeiture 
of  recoupment  rights  or  termination due  to  the  exhaustion  of  merchantable  and  mineable reserves.  Consideration  received in 
conjunction with a modification of an ongoing lease will be deferred and recognized straight-line over the remaining term of the 
contract. Consideration received to assign a lease to another party and related forfeited minimums will be recognized immediately 
upon the termination of the contract. Fees from contract modifications are recognized in Lease modification fees within Coal 
royalty and other revenues on our Consolidated Statements of Comprehensive Income while modifications in royalty rates and 
minimums will be recognized prospectively in accordance with the above lease classification.

In accordance with the transition guidance in paragraph 606-10-65-1, revenues from contracts that were modified before 
January  1,  2018  were  not  retrospectively  restated  for  those  modifications  and  instead  reflected  the  aggregate  effect  of  those 
modifications  when  identifying  the  satisfied  and  unsatisfied  performance  obligations,  determining  the  transaction  price  and 
allocating the transaction price to the satisfied and unsatisfied performance obligation.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—CONTINUED

Contract Assets and Liabilities from Contracts with Customers

Contract assets include receivables from contracts with customers and are recorded when the right to consideration becomes 
unconditional. Receivables are recognized when the minimums are contractually owed, production occurs or minimums accrued 
for based on the passage of time.

Contract liabilities represent minimum consideration received, contractually owed or earned based on the passage of time. 
The current portion of deferred revenue relates to deferred revenue on minimum leases and lease modification fees that are to be 
recognized as revenue on a straight-line basis over the next twelve months. The long-term portion of deferred revenue relates to 
deferred revenue on production leases and lease modification fees that are to be recognized as revenue on a straight-line basis 
beyond the next twelve months. Due to uncertainty in the amount of deferred revenue that will be recouped and recognized as 
Coal royalty revenue from its production leases over the next twelve months, the Partnership is unable to estimate the current 
portion of deferred revenue. 

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

adopting the new revenue recognition standard in January 2018.  

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. The Partnership's 49% investment in Ciner 
Wyoming is accounted for 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 attributed to net tangible assets and is 
amortized over its estimated useful life. The carrying value in Ciner Wyoming is recognized in Equity in unconsolidated investment 
in the Partnership's Consolidated Balance Sheets. The Partnership's adjusted share of the earnings or losses of Ciner Wyoming and 
amortization of the basis difference is recognized in Equity in earnings of Ciner Wyoming in the Consolidated Statements of 
Comprehensive Income. The Partnership increases its investment for its proportional share of distributions received from Ciner 
Wyoming. These cash flows are reported utilizing the cumulative earnings approach. Under this approach, distributions received 
are considered returns on investment and classified as operating cash inflows unless the cumulative distributions received exceed 
the Partnership's cumulative equity in earnings. The excess of cumulative distributions received over the Partnership's cumulative 
equity in earnings are considered returns of investment and classified as investing cash inflows. 

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.

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 services (or Transportation and processing services—affiliates) and Operating and maintenance 
expenses or (Operating and maintenance expenses—affiliates), respectively, in the Consolidated Statements of Comprehensive 
Income.  Subsequent  to  May  9,  2017,  Foresight  Energy  is  no  longer  deemed  a  related  party.  Refer  to  Note  15.  Related  Party 
Transactions for further details. 

Unit-Based Compensation

The Partnership has awarded unit-based compensation in the form of equity-based awards and phantom units. Compensation 
cost is measured at the grant date for equity-classified awards and remeasured each reporting period for liability-classified awards 
based on the fair value of an award and is recognized over the service period, which is generally the vesting period. Forfeitures 
are recognized as they occur. Unit-based compensation expense for all awards is recognized in General and administrative expense 
and Operating and maintenance expense in the Consolidated Statements of Comprehensive Income. 

79

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

Deferred Financing Costs

Deferred financing costs consist of legal and other costs related to the issuance of the Partnership’s debt. These costs are 
amortized over the term of the respective line-of-credit or debt arrangements. Deferred financing costs related to the Partnership's 
revolving  credit  facility  are  included  in  Other  assets  (long-term)  on  the  Partnership's  Consolidated  Balance  Sheets.  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 Current portion of long-term debt, net or 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 unitholders 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 unitholders could be changed if an adjustment 
in the Partnership’s income is ultimately sustained by the taxing authorities.

Recently Adopted Accounting Standards

Revenue Recognition 

On January 1, 2018, NRP adopted Accounting Standards Codification (ASC) 606, Revenue from Contracts with Customers,
and all the related amendments (the “new revenue standard” and "ASC 606") to all open contracts using the modified retrospective 
method. The adoption of the new revenue standard impacted royalty revenue from NRP's coal and aggregates royalty leases as 
further described below. NRP recognized a $70.5 million cumulative effect of adoption adjustment in the opening balance of 
partners' capital on January 1, 2018. Prior year information has not been restated and continues to be reported under the accounting 
standards in effect for those periods. The new revenue standard had no impact on revenues from NRP's Soda Ash operating segment 
or on the discontinued operations.

A majority of NRP’s coal and aggregates royalty revenue continues to be recognized over the lease term based on production. 
For  coal  and  aggregates  royalty  leases  for  which  NRP  expects  consideration  from  minimum  payments  to  be  greater  than 
consideration from production over the lease term, royalty revenue is now recognized straight-line over the lease term based on 
the minimum payment consideration.  The cumulative effects of the changes made to the Partnership's Consolidated Balance Sheet 
at January 1, 2018 for the adoption of the new revenue standard were as follows:

and Hillsboro lawsuits, the majority of which was previously recognized in partners' capital upon adoption and $7.2 million
of modification fees and forfeited recoupable balances related to fourth quarter 2018 lease modifications which were deferred 
under ASC 606 and will be recognized straight-line over the respective modified lease terms. 

Recently Issued Accounting Standards

Leases 

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). The new standard requires a lessee 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 standard does not apply to leases that 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 15, 2018 and is to be adopted using a modified retrospective approach. The Partnership will adopt this standard 
effective January 1, 2019 and does not expect that the provisions of this guidance will have a material impact on its consolidated 
financial statements.

4.    Discontinued Operations 

In December 2018, the Partnership sold VantaCore Partners LLC, its construction aggregates materials business for $205 
million,  before  customary  purchase  price  adjustments  and  transaction  expenses,  and  recorded  a  gain  of  $13.1  million.  The 
Partnership's debt agreements require that 75% of the asset sale proceeds be used to pay down the Opco Revolving Credit Facility 
(as defined in Note 13. Debt, Net) and 25% be offered to the holders of its Opco Senior Notes (as defined in Note 13. Debt, Net) 
on a pro-rata basis. The outstanding balance was repaid on the Opco Revolving Credit Facility in December 2018, $49 million
was offered to the holders of the Opco Senior Notes in December 2018 and paid in January 2019 and the remaining $55 million
of net cash proceeds was restricted as of December 31, 2018. NRP intends to use these remaining proceeds to repay its Opco Senior 
Notes as they amortize in 2019.

In July 2016, NRP Oil and Gas LLC ("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 both its construction aggregates materials business and non-operated oil and gas working interest 
business represented strategic shifts to reduce debt and focus on its Coal Royalty and Other and Soda Ash business segments. As 
a result, the Partnership classified the assets and liabilities, operating results and cash flows of these businesses as discontinued 
operations in its Consolidated Balance Sheets, Consolidated Statements of Comprehensive Income and Consolidated Statements

5.    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.  

87

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

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 
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. 

88

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

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. 

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:

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.

During the three months ended March 31, 2018, the Partnership redeemed all of the outstanding PIK Units, which resulted 

in an $8.8 million cash payment during the period.

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.

6.    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. As discussed in Note 5. Class A Convertible Preferred Units and Warrants above, the Partnership also makes distributions 
to the preferred unitholders. 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 ("GP") 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 declared and paid to common unitholders during the years ended December 
31, 2018, 2017 and 2016, respectively:

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, 2018 and 2017, NRP reduced net income attributable to common unitholders 
and the general partner by $30.0 million and $25.5 million, respectively as a result of accumulated Preferred Unit distributions 
earned during the period. The $7.5 million preferred unit distribution earned during the three months ended December 31, 2018
was paid on February 14, 2019. 

7.    Net Income Per Common Unit 

Basic  net  income  per  common  unit  is  computed  by  dividing  net  income,  after  considering  income  attributable  to  non-
controlling interest, preferred unitholders and the general partner’s general partner interest, by the weighted average number of 
common units outstanding. Diluted net income per common unit includes the effect of NRP's Preferred Units and Warrants, if the 
inclusion of these items is 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. 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.  

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 years ended December 31, 2018 and 2017 includes the net settlement of Warrants to purchase 
1.75 million common units with a strike price of $22.81 but 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.

8.    Segment Information 

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

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

Coal Royalty and Other—consists primarily of coal royalty and coal-related transportation and processing assets. Other 
assets include industrial minerals royalty properties, aggregates royalty properties, oil and gas royalty properties and timber. The 
Partnership's coal reserves are primarily located in Appalachia, the Illinois Basin and the Northern Powder River Basin in the 
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 Ciner Wyoming, a trona ore mining operation 
and soda ash refinery in the Green River Basin of 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 to the glass and chemicals 
industries.

In December 2018, the Partnership sold its construction aggregates business for $205 million, before customary purchase 
price adjustments and transaction expenses, and recorded a gain of $13.1 million. The Partnership's exit from the construction 
aggregates business enabled it to further reduce debt, focus on its Coal Royalty and Other and Soda Ash business segments and 
represented a strategic shift as it exited the operations of its construction aggregates business. The gain on sale and operating results 
of the construction aggregates business is included in Income from discontinued operations on the Consolidated Statements of 
Comprehensive Income and the net cash proceeds received is included in Cash provided by investing activities of discontinued 
operations  in  the  Partnership's  Consolidated  Statements  of  Cash  Flows  for  the  year  ended  December  31,  2018.  See  Note  4. 
Discontinued Operations for more information. 

Direct segment costs and certain other costs incurred at the corporate level that are identifiable and that benefit the Partnership's 
segments are allocated to the operating segments accordingly. These allocated costs generally include insurance, 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. 

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 
and administrative expenses—affiliates on the Consolidated Statements of Comprehensive Income.

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 
"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 issuance cost, capitalized and shown net of the debt 
liability on the Partnership's Consolidated Balance Sheets.

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

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, as defined below. None of NRP's subsidiaries guarantee the 2022 Senior Notes.

As of December 31, 2018 and December 31, 2017, NRP and NRP Finance were in compliance with the terms of their 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 of December 31, 2018 and 2017, 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.  
As of December 31, 2018, Opco had $100 million in available borrowing capacity under the Opco Credit Facility. As discussed 
in Note 4. Discontinued Operations, in December 2018 the Partnership repaid the outstanding balance of the Opco Credit Facility 
as a result of the sale of its construction aggregates business. 

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

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—CONTINUED

The  weighted  average  interest  rates  for  the  borrowings  outstanding  under  the  Opco  Credit  Facility  for  the  years  ended 
December 31, 2018 and 2017 were 6.23% and 5.32%, respectively. Debt issuance costs related to the OpCo credit facility were 
$1.7 million and $4.6 million at December 31, 2018 and 2017, 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. 

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 $548.9 
million and $553.9 million classified as Plant and equipment and Mineral rights as of December 31, 2018 and 2017, respectively, 
and $95.7 million included in Long-term assets of discontinued operations on the Partnership’s Consolidated Balance Sheets as 
of December 31, 2017. 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, 
and (4) 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, 2018 and 2017, the Opco Senior Notes had cumulative principal balances of $341.5 
million and $422.2 million, respectively. Opco made mandatory principal payments on the Opco Senior Notes of $80.7 million, 
$80.8 million and $82.9 million for the years ended December 31, 2018, 2017 and 2016, respectively. As discussed in Note 4. 
Discontinued Operations, as a result of the sale of the Partnership's construction aggregates business, $49 million was offered to 
the holders of the Opco Senior Notes and paid during the first quarter of 2019. The remaining $55 million of net cash proceeds 
from the sale of the construction aggregates business is restricted and the Partnership intends to use these remaining proceeds to 
repay its Opco Senior Notes as they amortize in 2019.

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.

103

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

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, 2018. 

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 Assets and Liabilities

The Partnership’s financial assets and liabilities consist of cash and cash equivalents, restricted cash, contracts receivable, 
debt, Preferred Units and Warrants. The carrying amounts reported on the Consolidated Balance Sheets for cash and cash equivalents 
and restricted cash 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, 2018 or 2017.

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:

(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.

(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 on the 
Partnership'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 quarterly, and changes in their fair value would be 
recorded in Other expense, net in the Partnership's Consolidated Statements of Comprehensive Income. The embedded derivatives 
had zero value as of December 31, 2018 and 2017.

Fair Value of Non-Financial Assets

The Partnership discloses or recognizes its non-financial assets, such as impairments of coal and aggregates properties and 
other assets, at fair value on a nonrecurring basis. Refer to Note 10. Plant and Equipment, Net and Note 11. Mineral Rights, Net
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 (GP) LP, NRP's general partner ("NRP GP"), through May 9, 2017. On May 9, 2017, Adena sold its 31% limited partner 
interest in 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. In  addition,  NRP  owns  a  contractual 
overriding royalty interest at Foresight Energy's Sugar Camp mine in the Illinois Basin which provides for payments based upon 
production from specific tons at Foresight Energy's Sugar Camp operations on certain reserves owned by another affiliate of Chris 
Cline. This overriding royalty is accounted for as a financing arrangement. Revenues related to these transactions are included in 
Coal royalty and other revenues in the Partnership's Consolidated Statements of Comprehensive Income.

Transportation and Processing Services Revenues and Expenses

The Partnership owns transportation and processing infrastructure related to certain of its coal properties, including loadout 
and other transportation assets at Foresight Energy's Williamson and Macoupin mines in the Illinois Basin, for which it collects 
throughput fees. These fees are included in Transportation and processing services revenues in the Partnership's Consolidated 
Statements of Comprehensive Income. 

NRP is responsible for operating and maintaining the rail loadout transportation assets at the Williamson mine and subcontracts 
the operating responsibilities to a subsidiary of Foresight Energy. Expenses related to these operations are included in Operating 
and maintenance expenses in the Partnership's Consolidated Statements of Comprehensive Income.

In addition, NRP owns rail loadout and associated infrastructure at the Sugar Camp mine, an Illinois Basin mine also operated 
by a subsidiary of Foresight Energy LP. While the Partnership owns coal reserves at the Williamson and Macoupin mines, it does 
not own coal reserves at the Sugar Camp mine. The infrastructure at the Sugar Camp mine is leased to a subsidiary of Foresight 
Energy and NRP collects throughput fees, which are included in Transportation and processing services revenues in the Partnership's 
Consolidated Statements of Comprehensive Income. 

NRP's Sugar Camp rail loadout lease with a subsidiary of Foresight Energy is accounted for as a financing lease. Minimum 
lease payments are $5.0 million per year for the next five years and represent a $1.25 million per quarter deficiency payment. The

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, 2018, 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. During the second quarter of 2018, Corsa assigned its lease with NRP to a third party and is no longer deemed 
a related party.

Coal related revenues from Corsa totaled $0.5 million, $1.3 million and $2.2 million for the years ended December 31, 2018, 
2017 and 2016. At December 31, 2017, the Partnership had Accounts receivable—affiliates totaling $0.2 million from Corsa on

17.    Commitments and Contingencies 

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. During the year ended 2018, NRP was also involved 
in the matters 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 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 in the District Court of Harris County, Texas, 157th 
Judicial District. The complaint alleged 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  is  vigorously  defending  this  lawsuit. However,  the  ultimate 
outcome cannot be predicted with certainty 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 Settlement

In October 2018, NRP's lawsuits against Foresight Energy and its subsidiaries Hillsboro Energy and Macoupin Energy were 
settled. The Hillsboro suit was pending in the Circuit Court of the Fourth Judicial Circuit in Montgomery County, Illinois, and the 
Macoupin suit was pending in Macoupin County, Illinois. NRP received a payment of $25 million from Foresight Energy in full 
settlement of the Hillsboro litigation, which was recognized immediately as Gain on litigation settlement in the Consolidated 
Statement of Comprehensive Income. In addition, NRP and Hillsboro Energy amended the coal mining lease with respect to the 
Deer Run mine to change the $30 million recoupable annual minimum royalty payments to $11 million non-recoupable annual 
minimum payments effective January 1, 2019 and extended the current lease term through the end of 2033. Furthermore, Foresight 
Energy forfeited its recoupable balances under the Macoupin and Hillsboro leases totaling approximately $37.4 million, the majority 
of which NRP previously recognized in Cumulative effect of adoption of accounting standard in Partners' capital on its Consolidated 
Balance Sheet on January 1, 2018. All claims were dismissed in both the Hillsboro and Macoupin lawsuits.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—CONTINUED

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 
"Items 1. and 2. Business and Properties—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,  2018.  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. 

As a former owner of the 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.    Unit-Based Compensation

2017 Long-Term Incentive Plan 

In December 2017, the 2017 Long-Term Incentive Plan (the “2017 LTIP”) was approved and it became effective in January 
2018. The 2017 LTIP authorizes 800,000 common units that are available for delivery by the Partnership pursuant to awards under 
the plan. The term is 10 years from the date of Board approval or, if earlier, the date the 2017 LTIP is terminated by the Board or 
the committee appointed by the Board to administer the 2017 LTIP, or the date all available common units available have been 
delivered. Common units delivered pursuant to the 2017 LTIP will consist, in whole or part, of (i) common units acquired in the 
open market, (ii) common units acquired from the Partnership (including newly issued units), any of our affiliates or any other 
person or (iii) any combination of the foregoing.

Employees, consultants and non-employee directors of the Partnership, the General Partner, GP LLC and their affiliates are 
generally eligible to receive awards under the 2017 LTIP. The 2017 LTIP provides for the issuance of a variety of equity-based 
grants, including grants of (i) options, (ii) unit appreciation rights, (iii) restricted units, (iv) phantom units, (v) cash awards, (vi) 
performance  awards,  (vii)  distribution  equivalent  rights,  and  (viii)  other  unit-based  awards.  The  plan  is  administered  by  the 
Compensation, Nominating and Governance Committee of the Board, which determines the terms and conditions of awards granted 
under the 2017 LTIP. The Partnership recognizes forfeitures for any awards issued under this plan as they occur.

Unit-Based Awards

Unit-based  awards  under  the  2017  LTIP  are  generally  issued  to  certain  employees  and  non-employee  directors  of  the 
Partnership. Awards granted to employees vest at the end of a 3 year period and awards granted to non-employee directors are 
immediately vested. Directors are given the option to take immediate issuance of the vested awards or defer such issuance until a 
later date. Upon deferral of issuance, such units will continue to accumulate DERs until issuance. 

In connection with the phantom unit awards, the Compensation, Nominating and Governance Committee also granted tandem 
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.

The awards granted in the first quarter of 2018 were valued using the closing price of NRP's units as of the grant date. The 
grant date fair value of the 2017 LTIP awards granted during the period was $2.2 million, including awards granted to board 
members with a grant date fair value of $0.6 million which immediately vested and of which $0.4 million were issued. Total unit-
based compensation expense recorded in the year ended December 31, 2018 associated with these awards was $1.0 million and 
$0.1  million  included  in  General  and  administrative  expense  and  Operating  and  maintenance  expense,  respectively,  in  the 
Partnership's Consolidated Statements of Comprehensive Income. The unamortized cost associated with unvested outstanding 
awards as of December 31, 2018 is $1.2 million, which is to be recognized over a weighted average period of 2.1 years.

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, 2018. 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, 2018 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, 2018 
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,  2018,  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.

Report of Independent Registered Public Accounting Firm

The Partners of Natural Resource Partners L.P.

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, 2018, 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, 2018, 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,  2018  and  2017,  the  related 
consolidated statements of comprehensive income, partners’ capital and cash flows for each of the three years in the period ended 
December 31, 2018, and the related notes and our report dated March 7, 2019 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.

Corporate Governance

Board Meetings and Executive Sessions

The Board met 10 times in 2018. During 2018, 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 2018. Mr. Vecellio was the 
presiding director at that meeting. Interested parties may communicate with our non-management directors by writing a letter to 
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. Claro, Gordy, 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. Because we are a limited partnership as defined in Section 303A of the NYSE’s listing standards, we are not 
required to have a majority of independent directors on the Board. 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.

Audit Committee

Our Audit Committee is currently comprised of Mr. Smith, who serves as chairman, Mr. Claro and Mr. Navarre. Mr. Smith,  
Mr. Claro, and Mr. Navarre are "Audit Committee Financial Experts" as determined pursuant to Item 407 of Regulation S-K. 
During 2018, the Audit Committee met seven times. Mr. Claro joined the Audit Committee effective March 2, 2018. Mr. Gordy 
served as a member of the Audit Committee from January 1, 2018 through March 1, 2018.

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 2018, 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, 2018 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 2018 was compatible with the auditors’ independence.

126

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 2018, 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, 2018, 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.  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 2018, 
the CNG Committee met two 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 2017, 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 2018. On June 11, 2018, Mr. Murphy filed 
a Form 4 reporting purchase of 3,159 common units on June 5, 2018 and 3,659 common units on June 6, 2018 that had not been 
previously reported on a timely basis.

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.

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

ITEM 11.  EXECUTIVE COMPENSATION 

Compensation Discussion and Analysis

Overview

As a publicly traded partnership, we have a unique employment and compensation structure that is different from that of a 
typical  public  corporation.  Our  executive  officers  based  in  Houston, Texas  are  employed  by  Quintana  Minerals  Corporation 
(“Quintana”), and our executive officers based in Huntington, West Virginia are employed by Western Pocahontas Properties 
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 "Items 1. and 2. Business and 
Properties—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 

•  Christopher J. Zolas—Chief Financial Officer and Treasurer

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

• 

• 

Jennifer L. Odinet—Chief Accounting Officer

Perry W. Donahoo—Former Chief Executive Officer—VantaCore

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 under current market conditions. Incentive compensation for the year ended December 31, 2018 was 
discretionary  but  certain  performance  criteria  were  considered  as  factors,  as  further  described  under  “—Components  of 
Compensation.”

The 2018 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.

All our named executive officers, other than Corbin J. Robertson, Jr., our Chairman and Chief Executive Officer, spent 100% 
of their time on NRP matters during 2018, and NRP bears the proportionate cost of their time. Mr. Robertson does not receive a 
salary in his capacity as Chief Executive Officer. Mr. Robertson is compensated through short-term cash and long-term equity 
incentive awards.

129

Historically, in February of each year, the CNG Committee has approved the short-term cash incentive award 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 were 
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 vested four years from the date of grant, with the last grants of these awards vested in February 2019.  
We refer to these phantom units as “Cash Settled Phantom Units.”  

In December 2017, the CNG Committee approved and the Board adopted the Natural Resource Partners 2017 Long-Term 
Incentive Plan (the “2017 Plan”), subject to unitholder approval. On December 20, 2017, unitholders holding the requisite percentage 
of votes necessary to approve the 2017 Plan approved the 2017 Plan by written consent in lieu of a special meeting of unitholders. 
The 2017 Plan became effective on January 16, 2018. Beginning in February 2018, the CNG Committee has made awards of 
phantom units to be settled in common units under the 2017 Plan to NRP’s officers in order to incentivize management while also 
aligning the long-term interests of management with the interests of NRP’s unitholders.

Role of Compensation Experts

Neither the Board nor the CNG Committee retained any consultants to evaluate compensation of officers or directors in 2018.

Role of Our Executive Officers in the Compensation Process

With respect to 2018 salaries and short-term cash incentive awards and long-term equity incentive awards, Mr. Nunez, our 
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 with recommendations for all of 
the  executive  officers  other  than  himself.  Messrs. Robertson  and  Nunez  considered  the  factors  described  elsewhere  in  this 
compensation discussion and analysis in recommending, in their discretion, the appropriate amounts for each named executive 
officer. Messrs. Robertson and Nunez attended the CNG Committee meetings at which the Committee deliberated and approved 
2018 salaries, short-term cash incentive awards and long-term equity incentive awards 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 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 2018, at the December 2017 meeting, the CNG Committee considered 
the financial performance of NRP for the nine months ended September 30, 2017 as well as the projected financial performance 
of NRP for the fourth quarter of 2017 and for the year ending December 31, 2018. The CNG Committee also considered the 
individual performance of each member of the executive management team during 2017. Salaries for 2018 are shown in the 
Summary Compensation Table below.

130

Short-Term Cash Incentive Compensation

Each named executive officer received a discretionary short-term cash incentive award approved in February 2019 by the 
CNG Committee. The amounts awarded with respect to 2018 under this program are disclosed in the Summary Compensation 
Table under the Bonus column. With respect to 2018, the CNG Committee provided general guidelines that cash bonuses would 
be paid based on a range of 60% to 140% of base salary, with Mr. Robertson receiving two times the amount awarded to the 
President and Chief Operating Officer. In addition, the CNG Committee determined that it would consider certain criteria to 
determine bonus amounts within this range, but that the criteria utilized at the time of determination, as well as the relative weight 
of those criteria, would be generally discretionary and subject to change based on developments at the company.  

Long-Term Equity Incentive Compensation

Each named executive officer received a discretionary long-term equity incentive award in 2018 under the 2017 Plan. The 
2018 awards were made in the form of phantom units that will settle in NRP common units on a one-for-one basis following vesting 
in February 2021 and will accrue DERs to be paid in cash upon settlement. We refer to these phantom units issued in 2018 as 
“2017 Plan Phantom Units.” The 2017 Plan Phantom Units are subject to forfeiture and will vest on an accelerated basis following 
death or disability of the award recipient or following a change in control of NRP. The grant date fair value of the 2017 Plan 
Phantom Units awarded in 2018 are disclosed in the Summary Compensation Table under the Stock Awards column. For the 2017 
Plan Phantom Units awarded in 2018, the CNG Committee generally awarded an amount equal to 60% of base salary, with Mr. 
Robertson receiving two times the amount awarded to the President and Chief Operating Officer. The CNG Committee considered 
performance of the company and individual performance in making these awards, as well as the cash incentive awards received 
by certain of the named executive officers in March 2017.

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.

In 2018, Quintana and Western Pocahontas maintained tax-qualified 401(k) and defined contribution retirement plans. During 
2018, Quintana and Western Pocahontas matched 100% of the first 6.0% of the employee contributions under their respective 
401(k) plans. 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

NRP maintains Unit Ownership and Retention Guidelines (the “ownership guidelines”) that are administered by the CNG 
Committee and 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 NRP’s Chief 
Financial Officer is for such individual to hold common units having a value of two times his or her base salary at the date of 
measurement. The guideline for NRP’s Vice President & General Counsel and Chief Accounting Officer is for such individuals 
to hold common units having a value of one and one-half 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).

131

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).

Incentive Compensation Recoupment Policy

NRP maintains the Natural Resource Partners L.P. Incentive Compensation Recoupment Policy, which is 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, 2018.

Compensation Committee Interlocks and Insider Participation

 During the year ended December 31, 2018, Messrs. Vecellio, Gordy, and Smith served on the CNG Committee. None of 
Messrs. Vecellio, Gordy, and Smith 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 us, including our executive officers, are employed by Quintana or Western Pocahontas.  
As of December 31, 2018, 57 such persons were providing services to us. We identified a new median service provider in 2018 
by examining the 2018 total taxable compensation, as reflected in our payroll records as reported to the Internal Revenue Service 
on  Form  W-2,  for  all  individuals  who  provided  services  to  us  as  of  December  31,  2018.  The  calculation  does  not  include 
compensation paid to employees of the VantaCore construction aggregates business sold in December 2018. 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 service providers that were not employed for all of 2018.

After identifying the median service provider based on total compensation, we calculated annual 2018 compensation for the 
median service provider using the same methodology used to calculate the Chief Executive Officer’s total compensation as reflected 
in the Summary Compensation Table above. The median service provider’s annual 2018 compensation was as follows:

Our 2018 ratio of Chief Executive Officer total compensation to our median service provider's total compensation is 

reasonably estimated to be 14:1.

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.

• 

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.

140

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.

141

Board Representation and Observation Rights Agreement

Effective on March 2, 2017 in connection with the closing of the issuance of the Preferred Units, we entered into the Board 
Observation and Representation Rights Agreement (the “Board Rights Agreement”) with Blackstone and GoldenTree. Pursuant 
to the Board Rights Agreement, Blackstone appoints one member to serve on the Board of Directors of GP Natural Resource 
Partners LLC and also appoints 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 "Item 8. Financial Statements and Supplementary Data—Note 5. Class A Convertible Preferred Units 
and Warrants" elsewhere 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). 

As a result of the Adena Sale, we no longer consider Cline or his affiliates, including Foresight Energy, affiliates of NRP. 
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 and Foresight Energy" 
elsewhere in this Annual Report on Form 10-K..

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."

142

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:

• 

• 

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." and —Quinwood Coal Company 
Royalty.

Office Building in Huntington, West Virginia

We lease an office building in Huntington, West Virginia from Western Pocahontas Properties Limited Partnership. The 
initial 10-year term of the lease expired at the end of 2018. On January 1, 2019 we entered into a new lease on the building for a 
five-year base term, with five additional five-year renewal options. During the years ended December 31, 2018 and 2017, we paid 
approximately $0.6 million in rent each year to Western Pocahontas under the lease. 

143

Relationship with Cadence Bank, N.A.

Paul B. Murphy, Jr. one of the members of the Board of Directors of GP Natural Resource Partners LLC, is the Chairman 
of Cadence Bank, N.A., which is a lender under NRP Operating’s revolving credit facility and has received customary fees and 
interest payments in connection therewith. During the years ended December 31, 2018 and 2017, we paid approximately $0.6 
million and $0.3 million, respectively in interest and fees under the credit facility to Cadence Bank, N.A.

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.

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.

144

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. We rely on officers and employees of GP Natural Resource Partners LLC and its 
affiliates.

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.

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.

145

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

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.

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.

147

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 
Stephen P. Smith, the Chairman of the Audit Committee. Mr. Smith 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.

148

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.

This  GENERAL  RELEASE  OF  CLAIMS  (this  “Agreement”)  is  entered  into  by  Perry 
Donahoo  (“Employee”)  and  is  that  certain  Release  defined  in  Section  6  of  the  Employment

LLC has purchased all of the Equity Interests (as defined in the Purchase and Sale Agreement) in

thousand three hundred fifty-seven dollars ($1,867,357) on or before the date that is one business 
day after the Closing Date. Additionally, if (a) Employee executes this Agreement on or after the 
Separation Date and returns it to the Company, care of Sarah Watson at 1201 Louisiana Street 34th
Floor Houston, Texas 77002 (swatson@nrplp.com) so that it is received by Ms. Watson no later 
than 11:59 p.m. Houston, Texas time on January 24, 2019, (b) does not exercise his revocation rights 
pursuant  to  Section  11  below,  and  (c)  abides  by  Employee’s  continuing  obligations  under  the 
Employment Agreement (including the terms of Section 5 thereof), then the Company will –

(a)         provide Employee the payments and benefits set forth in Section 4(d) of the 

Employment Agreement, subject to the terms of the Employment Agreement; and

(b)        waive Employee’s continuing obligations under Sections 5(c) and 5(d) of the 

Employment Agreement effective on the expiration of the Release Revocation Period.

The payments and benefits set forth in clauses (a) and (b) above are referred to herein collectively 
as the “Severance Benefits.”

2.               Satisfaction  of  All  Leaves  and  Payment  Amounts;  Prior  Rights  and 
Obligations.  In entering into this Agreement, Employee expressly acknowledges and agrees that 
Employee  has  received  all  leaves  (paid  and  unpaid)  to  which  Employee  was  entitled  during 
Employee’s employment with the Company and any other Company Party (as defined below) and 
Employee has received all wages, bonuses, and other compensation, been provided all benefits, 
been afforded all rights and been paid all sums that Employee is owed and has been owed or could 
ever be owed by the Company and any other Company Party as of the date that Employee executes 
this Agreement (the “Signing Date”). For the avoidance of doubt, Employee acknowledges and 
agrees  that  Employee  had  no  right  to  the  Severance  Benefits  (or  any  portions  thereof)  but  for 
Employee’s entry into this Agreement.

3.              Release of Liability for Claims.

(a) 

In consideration of Employee’s receipt of the Severance Benefits (and any 
portion thereof), Employee hereby forever releases, discharges and acquits the Company, Western 
Pocahontas  Properties  Limited  Partnership,  Natural  Resource  Partners  L.P.,  their  respective 
affiliates,  and  each  of  the  foregoing  entities’  respective  past,  present  and  future  subsidiaries, 
affiliates,  stockholders,  members,  partners,  directors,  officers,  managers,  insurers,  employees, 
agents,  attorneys,  heirs,  predecessors,  successors  and  representatives  in  their  personal  and 
representative capacities, as well as all employee benefit plans maintained by any of the foregoing 
and  all  fiduciaries  and  administrators  of  any  such  plans,  in  their  personal  and  representative 
capacities (collectively, the “Company Parties”), from liability for, and Employee hereby waives, 
any and all claims, damages, or causes of action of any kind related to Employee’s employment 
with any Company Party, the termination of such employment, and any other acts or omissions 
related to any matter occurring or existing on or prior to the Signing Date, including (i) any alleged 
violation through such date of: (A) any federal, state or local anti-discrimination or anti-retaliation 
law,  including  the Age  Discrimination  in  Employment Act  of  1967,  as  amended  (including  as 
amended by the Older Workers Benefit Protection Act), Title VII of the Civil Rights Act of 1964, 
as amended, the Civil Rights Act of 1991, as amended, and Sections 1981 through 1988 of Title 42 
of the United States Code, as amended; and the Americans with Disabilities Act of 1990, as amended; 
(B)  the  Employee  Retirement  Income  Security Act  of  1974,  as  amended  (“ERISA”);  (C)  the 
Immigration Reform Control Act, as amended; (D) the Occupational Safety and Health Act, as 
amended; (E) the Family and Medical Leave Act of 1993; (F) any federal, state or local wage and 
hour law; (G) any other local, state or federal law, regulation or ordinance; or (H) any public policy, 
contract, tort, or common law claim or claim for fiduciary duty or breach thereof or claim for fraud 
or  misrepresentation  or  fraud  of  any  kind;  (ii)  any  allegation  for  costs,  fees,  or  other  expenses 
including attorneys’ fees incurred in, or with respect to, a Released Claim; (iii) any and all rights, 
benefits or claims Employee may have under any retention, change in control, bonus, long term 
incentive or severance plan or policy of any Company Party or any retention, change in control, 
bonus, long term incentive or severance-related agreement that Employee may have or have had 
with any Company Party other than the rights to the Severance Benefits described herein; (iv) any 
and all rights, benefits or claims Employee may have under any employment contract (including 
the Employment Agreement), equity-based compensation plan or arrangement (including the LTIP), 
incentive compensation plan, limited liability company agreements, and any other agreement; and 
(v) any claim for compensation or benefits of any kind not expressly set forth in this Agreement 
(collectively, the “Released Claims”). In no event shall the Released Claims include (x) any claim 
that first arises after the Signing Date (y) any claim to vested benefits under an employee benefit 
plan governed by ERISA, or (z) any claim arising after the Signing Date under any equity award 

agreement respecting Employee’s equity ownership in the Company or any other Company Party 
that survives the Employee’s Separation Date. This Agreement is not intended to indicate that any 
such claims exist or that, if they do exist, they are meritorious. Rather, Employee is simply agreeing 
that, in exchange for the Severance Benefits, any and all potential claims of this nature that Employee 
may have against the Company Parties, regardless of whether they actually exist, are expressly 
settled, compromised and waived.  THIS RELEASE INCLUDES MATTERS ATTRIBUTABLE 
TO  THE  SOLE  OR  PARTIAL  NEGLIGENCE  (WHETHER  GROSS  OR  SIMPLE)  OR 
OTHER  FAULT,  INCLUDING  STRICT  LIABILITY,  OF  ANY  OF  THE  COMPANY 
PARTIES.

(b) 

Notwithstanding this release of liability, nothing in this Agreement prevents 
Employee from filing any non-legally waivable claim (including a challenge to the validity of this 
Agreement) with the Equal Employment Opportunity Commission (“EEOC”) or comparable state 
or local agency or participating in (or cooperating with) any investigation or proceeding conducted 
by  the  EEOC  or  comparable  state  or  local  agency  or  cooperating  with  such  agency;  however, 
Employee  understands  and  agrees  that  Employee  is  waiving  any  and  all  rights  to  recover  any 
monetary or personal relief or recovery as a result of such EEOC or comparable state or local agency 
or proceeding or subsequent legal actions.

(c) 

Nothing in this Agreement shall prohibit or restrict Employee from lawfully 
(i) initiating communications directly with, cooperating with, providing information to, causing 
information  to  be  provided  to,  or  otherwise  assisting  in  an  investigation  by  any  Governmental 
Authorities regarding a possible violation of any law; (ii) responding to any inquiry or legal process 
directed  to  Employee  individually  from  any  such  Governmental  Authorities;  (iii)  testifying, 
participating or otherwise assisting in an action or proceeding by any such Governmental Authorities 
relating to a possible violation of law; or (iv) making any other disclosures that are protected under 
the whistleblower provisions of any applicable law. Additionally, pursuant to the federal Defend 
Trade Secrets Act of 2016, Employee shall not be held criminally or civilly liable under any federal 
or state trade secret law for the disclosure of a trade secret that: (i) is made (A) in confidence to a 
federal, state, or local government official, either directly or indirectly, or to an attorney; and (B) 
solely for the purpose of reporting or investigating a suspected violation of law; or (ii) is made to 
Employee’s attorney in relation to a lawsuit for retaliation against Employee for reporting a suspected 
violation  of  law;  or  (iii)  is  made  in  a  complaint  or  other  document  filed  in  a  lawsuit  or  other 
proceeding, if such filing is made under seal. Nothing in this Agreement requires Employee to obtain 
prior authorization from the Company before engaging in any conduct described in this paragraph, 
or to notify the Company that Employee has engaged in any such conduct.

(d) 

For the avoidance of doubt, nothing herein waives Employee’s future rights 
to indemnification or to the benefits of any directors and officers insurance, to the extent such rights 
and benefits exist pursuant to the terms of applicable bylaws, agreements or applicable plans, as 
each may be amended from time to time.

4.             Representation About Claims.  Employee represents and warrants that, as of the 
Signing Date, Employee has not filed any claims, complaints, charges, or lawsuits against any of 
the Company Parties with any governmental agency or with any state or federal court or arbitrator 
for or with respect to a matter, claim, or incident that occurred or arose out of one or more occurrences 
that  took  place  on  or  prior  to  the  Signing  Date.  Employee  further  represents  and  warrants  that 

Employee has made no assignment, sale, delivery, transfer or conveyance of any rights Employee 
has asserted or may have against any of the Company Parties with respect to any Released Claim.

5.             Employee’s Acknowledgments.  By executing and delivering this Agreement, 

Employee expressly acknowledges that:

(a)          Employee has carefully read this Agreement and has had sufficient time 
(and at least 45 days) to consider this Agreement before signing it and delivering it to the 
Company;

(b)         Employee has been advised, and hereby is advised in writing, to discuss this 
Agreement  with  an  attorney  of  Employee’s  choice  and  Employee  has  had  adequate 
opportunity to do so prior to executing this Agreement;

(c)         Employee fully understands the final and binding effect of this Agreement; 
the only promises made to Employee to sign this Agreement are those stated herein; and 
Employee is signing this Agreement knowingly, voluntarily and of Employee’s own free 
will, and understands and agrees to each of the terms of this Agreement;

(d)         The only matters relied upon by Employee and causing Employee to sign 
this Agreement  are  the  provisions  set  forth  in  writing  within  the  four  corners  of  this 
Agreement;

(e)         Employee would not otherwise have been entitled to the Severance Benefits, 
or  any  portion  thereof,  but  for  Employee’s  agreement  to  be  bound  by  the  terms  of  this 
Agreement; 

(f)         No  Company  Party  has  provided  any  tax  or  legal  advice  regarding  this 
Agreement and Employee has had the opportunity to receive sufficient tax and legal advice 
from advisors of Employee’s own choosing such that Employee enters into this Agreement 
with full understanding of the tax and legal implications thereof; and

(g)         Employee has been provided with, and attached to this Agreement as Exhibit 
A is, a listing of: (i) titles and ages of all individuals selected for participation in the program 
pursuant  to  which  Employee  is  being  offered  this Agreement;  (ii)  titles  and  ages  of  all 
individuals in the same decisional unit who were not selected for participation in the program; 
and (iii) information about the unit affected by the program, including any eligibility factors 
for such program and any time limits applicable to such program.

6.             Third-Party Beneficiaries.  Employee expressly acknowledges and agrees that 
each Company Party that is not a signatory to this Agreement shall be a third-party beneficiary of 
Employee’s release of claims and representations in Sections 2-5 and 9 hereof.

7.             Severability.  Any term or provision of this Agreement (or part thereof) that renders 
such term or provision (or part thereof) or any other term or provision hereof (or part thereof) invalid 
or unenforceable in any respect shall be severable and shall be modified or severed to the extent 
necessary to avoid rendering such term or provision (or part thereof) invalid or unenforceable, and 
such modification or severance shall be accomplished in the manner that most nearly preserves the 
benefit of the bargain set forth in the Employment Agreement and hereunder.

8.             Withholding of Taxes and Other Deductions.  Employee acknowledges that the 
Company may withhold from the Severance Benefits all federal, state, local, and other taxes and 
withholdings as may be required by any law or governmental regulation or ruling.

9.             Return  of  Property.    Employee  represents  and  warrants  that  Employee  has 
returned  to  the  Company  all  property  belonging  to  the  Company  or  any  other  Company  Party, 
including all computer files, electronically stored information and other materials provided to him 
by the Company or any other Company Party in the course of Employee’s employment with the 
Company and Employee further represents and warrants that Employee has not maintained a copy 
of any such materials in any form.

10.             Further Assurances.  In signing below, Employee expressly acknowledges the 
enforceability, and continued effectiveness of Section 5 of the Employment Agreement and promises 
to abide by those terms of the Employment Agreement to the extent such terms are not waived by 
the Company pursuant to Section 1.

11.             Revocation Right.  Notwithstanding the initial effectiveness of this Agreement, 
Employee may revoke the delivery (and therefore the effectiveness) of this Agreement within the 
seven-day period beginning on the Signing Date (such seven day period being referred to herein as 
the  “Release  Revocation  Period”). To  be  effective,  such  revocation  must  be  in  writing  signed 
Employee and must be received by Sarah Watson at 1201 Louisiana Street 34th Floor Houston, 
Texas 77002 (swatson@nrplp.com) before 11:59 p.m., Houston, Texas time, on the last day of the 
Release Revocation Period. If an effective revocation is delivered in the foregoing manner and 
timeframe, no Severance Benefits shall be provided and this Agreement shall be null and void; 
provided, however, that the provisions of Sections 2, 4, 9 and 10 shall remain in full force and effect 
and shall not be affected by any such revocation.

12.             Employment Agreement.  This Agreement shall be subject to the provisions of 
Sections  8,  10,  11,  15,  16  and  18  of  the  Employment Agreement,  which  provisions  are  hereby 
incorporated by reference as a part of this Agreement.

MINE SAFETY DISCLOSURE

Exhibit 95.1

We owned VantaCore Partners LLC, a construction aggregates business, through December 11, 2018. Effective 

December 11, 2018, we sold VantaCore Partners LLC to an unaffiliated third party. These 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 for the period from January 1, 2018 to December 
11, 2018.  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 period from January 1, 2018 to December 11, 2018.

(1)  Mine Act  section  104  S&S  citations  shown  above  are  for  alleged  violations  of  mandatory  health  or  safety  standards  that  could  significantly  and 
substantially contribute to a mine health and safety hazard.  It should be noted that, for purposes of this table, S&S citations that are included in another 
column, such as Section 104(d) citations, are not also included as Section 104 S&S citations in this column.  

(2)  Mine Act section 104(b) orders are for alleged failures to totally abate a citation within the time period specified in the citation.

(3)  Mine Act section 104(d) citations and orders are for an alleged unwarrantable failure (i.e., aggravated conduct constituting more than ordinary negligence)

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, 2018 and 2017, 
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, 2018 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, 2018 and 
2017, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2018, 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.

(Dollars in thousands)

1.  Corporate Structure

A 51% membership interest in Ciner Wyoming LLC (the "Company," "Ciner Wyoming," "we," "us," or "our") is owned 
by Ciner Resources LP ("Ciner Resources" or the "Partnership"). NRP Trona LLC, a wholly owned subsidiary of Natural 
Resource Partners LP ("NRP") owns a 49% membership interest in the Company.  Ciner Resources is a master limited 
partnership traded on the New York Stock Exchange and is currently owned approximately 73% by Ciner Wyoming 
Holding Co. ("Ciner Holdings"), approximately 2% by Ciner Resource Partners LLC (our “general partner” or “Ciner 
GP”) and approximately 25% by the general public. Ciner Holdings is 100% owned by Ciner Resources Corporation 
("Ciner Corp") which is 100% owned by Ciner Enterprises, Inc. ("Ciner Enterprises"). As of December 31, 2018, Ciner 
Enterprises was 100% owned by WE Soda Ltd., a U.K. corporation (“WE Soda”). WE Soda is a direct wholly-owned 
subsidiary of KEW Soda Ltd., a U.K. corporation (“KEW Soda”), which is a direct wholly-owned subsidiary of 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.

On February 22, 2018, Akkan transferred its direct 100% ownership in Ciner Enterprises to KEW Soda, a UK company, 
which transferred such ownership to WE Soda, a UK company.  WE Soda is 100% owned by KEW Soda, and KEW Soda 
is wholly owned by Akkan.  This reorganization is a part of Ciner Group’s strategy to combine the global soda ash 
business under a common structure in the UK.

2. Nature of Operations and Summary of Significant Accounting Policies

Nature of Operations - The Company operations consist of the mining of trona ore, which, when processed, becomes 
soda ash.  All our soda ash processed is sold to various domestic customers, and to Ciner Ic ve Dis Ticaret Anonim Sirketi 
("CIDT") and American Natural Soda Ash Corporation ("ANSAC") which are affiliates for export sales. The Company 
began selling soda ash in late 2016 to CIDT and continued into 2017. There were no sales to CIDT during the year ended 
December 31, 2018, as the contract terminated in 2017. All mining and processing activities take place in one facility 
located in Green River, Wyoming.

Recent Developments

Notice to Terminate Membership in ANSAC - On November 9, 2018, we were informed that Ciner Corp had delivered a 
notice to terminate its membership in ANSAC, a cooperative that serves as the primary international distribution channel 
for us as well as two other U.S. manufacturers of trona-based soda ash. The effective termination date is expected to be 
December 31, 2021. ANSAC was our largest customer for the years ended December 31, 2018, 2017 and 2016, 
accounting for 52.0%, 44.7% and 55.2%, respectively, of our net sales. Although ANSAC has been our largest customer 
for the years ended December 31, 2018, 2017, and 2016, we anticipate that the impact of such termination on our net 
sales, net income and liquidity will be limited. We made this determination primarily based upon the belief that we will 
continue to be one of the lowest cost producers of soda ash in the global market that has historically seen demand for soda 
ash exceed supply of soda ash, and therefore we anticipate being able to find export customers regardless of market 
conditions. Between now and the termination date, Ciner Corp will continue to have full ANSAC membership benefits 

8

and services.  After the termination period, Ciner Corp will sell soda ash directly into international markets that are 
currently being served by ANSAC and intends to utilize the distribution network that has already been established by the 
global Ciner Group. We believe by combining our volumes with Ciner Group’s soda ash exports from Turkey, our 
withdrawal from ANSAC will allow us to leverage the larger, global Ciner Group soda ash operations. We expect this will 
eventually lower our cost position and improve our ability to optimize our market share both domestically and 
internationally. The ANSAC agreement provides that 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. As of December 31, 2018, we have not recognized an asset or liability related to the exit from ANSAC as 
such an amount is not currently probable or estimable.

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 date 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 - On May 28, 2014 the Financial Accounting Standards Board (the “FASB”) issued Accounting 
Standards Codification (“ASC”) 606, 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 adopted this ASC effective January 1, 2018, as permitted by the ASC, 
using the modified retrospective method and we have not made any adjustment to opening retained earnings. The 
Company has applied the provisions of this ASC and notes that our adoption of ASC 606 does not materially change the 
amount or timing of revenues recognized by us, nor does it 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.  Additionally, the Company has made an accounting 
policy election to account for shipping and handling activities as fulfillment costs.

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, 2018 and 2017. 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. 

9

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.

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
Computer hardware
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 
qualifying for hedge accounting 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 
natural gas physical forward contracts are accounted for under the normal purchases and normal sales scope exception.

The Company has interest rate swap contracts, designated as cash flow hedges, to mitigate our exposure to possible 
increases in interest rates. The swap contracts consist of four individual $12,500 swaps with an aggregate notional value 
of $50,000 at December 31, 2018 and have various maturities through 2022. Our previous interest rate swap contracts, 
with an aggregate notional value of $70,000 as of December 31, 2017, expired on July 18, 2018. At December 31, 2018, 
it is anticipated that approximately $319 of losses currently recorded in accumulated other comprehensive income (loss) 
will be reclassified into earnings within the next twelve months.

The Company has entered into financial 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 2023. 
These contracts had an aggregate notional value of $41,206 and $37,087 at December 31, 2018 and December 31, 2017, 
respectively. Refer to footnote 12 for details surrounding both these physical and the financial portions of our natural gas 
forward contracts. At December 31, 2018, it was anticipated that $1,617 of losses currently recorded in accumulated other 
comprehensive income (loss) will be reclassified into earnings within the next twelve months.

Income Tax - The Company is organized as a pass-through entity for federal and most state income tax purposes. Taxes 
assessed by states 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.

11

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. During 2018, 2017 and 2016 the remaining estimated useful life of the mine was 
60 years, 66 years and 67 years, respectively. In 2019, the mining reserve will be amortized over a remaining life of 59 
years. 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 7, 2019, the date the financial 
statements were available to be issued.

Recently Issued Accounting Standards - In February 2016, the FASB issued ASU 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. For leases less than 12 months, an entity is permitted to make an accounting 
policy election by class of underlying asset not to recognize lease assets and lease liabilities. If a lessee makes this 
election, it should recognize lease expense for such leases generally on a straight-line basis over the lease term. The 
Company will make this election upon adoption. In preparation for the new requirements, the Company has completed its 

12

evaluation of the lease agreements. The Company adopted ASC 842 effective January 1, 2019 using a modified transition 
approach under which prior comparative periods will not be adjusted, as permitted by the guidance.  The Company has 
determined that the adoption of the new standard will not have a material impact on the balance sheet or statement of 
operations because the Company has no material long term leases that are subject to ASC 842. Ciner Corp was 
determined to be the ultimate lessee for rail car lease agreements under ASC 842, and the Company will continue to incur 
an allocation of rent expense in relation to the use of rail cars leased by Ciner Corp.

In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging (ASC Topic 815) - 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 
makes 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 adopted this ASU 
effective January 1, 2019 and the adoption did not have a material impact to the Company’s financial statements.

In accordance with ASC 350-40, Internal Use Software, we capitalize certain internal use software development costs 
associated with creating and enhancing internally developed software related to our enterprise resource planning system 
that was implemented in 2018 and went live on January 1, 2019. Software development activities generally consist of 
three stages (i) the research and planning stage, (ii) the application and infrastructure development stage, and (iii) the 
post-implementation stage. Costs incurred in the planning and post-implementation stages of software development, or 
other maintenance and development expenses that do not meet the qualification for capitalization are expensed as 
incurred. Costs incurred in the application and infrastructure development stage, including significant enhancements and 
upgrades, are capitalized. As a result, we have capitalized $6,191 of software development costs and $0 of accumulated 
amortization, as an intangible asset within “other non-current assets” in the balance sheet as of December 31, 2018. These 
software development costs are amortized on a straight-line basis over the estimated useful life of five to ten years under 
depreciation and amortization expense in the statements of operations. Amortization for these capitalized costs is 
expected to be approximately $600 per year during the amortization period.

On October 1, 2018 the Company fully extinguished the $11,400 Variable Rate Demand Revenue Bonds due on that day. 
The Bonds were paid in full, including all accrued interest and without penalties. Additionally, the extinguishment of the 
bonds relieved Ciner Wyoming of maintaining the related standby letters of credit.

Ciner Wyoming Credit Facility

On August 1, 2017, Ciner Wyoming 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 (“Former Ciner Wyoming Credit Facility”), dated as of July 18, 2013, by and among Ciner Wyoming, the lenders 
party thereto and Bank of America, N.A., as administrative agent, swing line lender and L/C issuer, as amended, 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 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 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 Ciner Wyoming receiving increased commitments from existing lenders or new commitments from new lenders and 
the satisfaction of certain other conditions. In addition, the Ciner Wyoming Credit Facility includes a sublimit up to 
$20,000 for same-day swing line advances and a sublimit up to $40,000 for letters of credit. Ciner Wyoming’s obligations 
under the Ciner Wyoming Credit Facility are unsecured.

The Ciner Wyoming Credit Facility contains various covenants and restrictive provisions that limit (subject to certain 
exceptions) Ciner Wyoming’s ability to:

•  make distributions on or redeem or repurchase units;

• 

incur or guarantee additional debt;

•  make certain investments and acquisitions;

• 

incur certain liens or permit them to exist;

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

•  merge or consolidate with another company; and

• 

transfer, sell or otherwise dispose of assets.

15

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 Ciner Wyoming may have. Upon the occurrence and during the 
continuation of an event of default, subject to the terms and conditions of the Ciner Wyoming Credit Facility, the 
administrative agent shall, at the request of the Required Lenders (as defined in the Ciner Wyoming Credit Facility), or 
may, with the consent of the Required Lenders, terminate all outstanding commitments under the Ciner Wyoming Credit 
Facility and may declare any outstanding principal of the Ciner Wyoming Credit Facility debt, together with accrued and 
unpaid interest, to be immediately due and payable.

Under the Ciner Wyoming Credit Facility, a change of control is triggered if Ciner Corp and its wholly-owned 
subsidiaries, directly or indirectly, cease to own all of the equity interests, or cease to have the ability to elect a majority 
of the board of directors (or similar governing body) of our general partner (or any entity that performs the functions of 
the Partnership’s general partner). In addition, a change of control would be triggered if the Partnership ceases to own at 
least 50.1% of the economic interests in Ciner Wyoming or ceases to have the ability to elect a majority of the members 
of Ciner Wyoming’s board of managers.

Loans under the Ciner Wyoming Credit Facility bear interest at Ciner Wyoming’s option at either:

•  a Base Rate, which equals the highest of (i) the federal funds rate in effect on such day plus 0.50%, (ii) the 
administrative agent’s prime rate in effect on such day or (iii) one-month LIBOR plus 1.0%, in each case, plus 
an applicable margin; or

•  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 consolidated leverage ratio.

At December 31, 2018, Ciner Wyoming was in compliance with all financial covenants of the Ciner Wyoming Credit 
Facility.

WE Soda and Ciner Enterprises Facilities Agreement

On August 1, 2018, Ciner Enterprises, the entity that indirectly owns and controls Ciner Wyoming, refinanced its existing 
credit agreement and entered into a new facilities agreement, to which WE Soda and Ciner Enterprises (as borrowers), 
and KEW Soda, WE Soda, certain related parties and Ciner Enterprises, Ciner Holdings and Ciner Corp (as original 
guarantors and together with the borrowers, the “Ciner obligors”), are parties (as amended and restated or otherwise 
modified, the “Facilities Agreement”), and certain related finance documents. The Facilities Agreement expires on August 
1, 2025.

Even though Ciner Wyoming is not a party or a guarantor under the Facilities Agreement, while any amounts are 
outstanding under the Facilities Agreement we will be indirectly affected by certain affirmative and restrictive covenants 
that apply to WE Soda and its subsidiaries (which includes us). Besides the customary covenants and restrictions, the 
Facilities Agreement includes provisions that, without a waiver or amendment approved by lenders whose commitments 
are more than 66-2/3% of the total commitments under the Facilities Agreement to undertake such action, would (i) 
prevent transactions with our affiliates that could reasonably be expected to materially and adversely affect the interests 
of certain finance parties, (ii) restrict the ability to amend the Company's agreement or Ciner Holdings' company 

16

agreement or Company's other constituency documents if such amendment could reasonably be expected to materially 
and adversely affect the interests of the lenders to the Facilities Agreement; and (iii) prevent actions that enable certain 
restrictions or prohibitions on our ability to upstream cash (including via distributions) to the borrowers under the 
Facilities Agreement.  In addition, Ciner Enterprises’ ownership in Ciner Holdings, is subject to a lien under the Facilities 
Agreement, which enables the lenders under the Facilities Agreement to foreclose on such collateral and take control of 
Ciner Holdings if any of WE Soda or KEW Soda or certain of their related parties, or Ciner Enterprises, Ciner Corp or 
Ciner Holdings is unable to satisfy its respective obligations under the Facilities Agreement.

10. EMPLOYEE BENEFIT PLANS

The Company participates in various benefit plans offered and administered by Ciner Corp and is allocated its portions of 
the annual costs related thereto. The specific plans are as follows:

Retirement Plans - Benefits provided under the pension plan for salaried employees and pension plan for hourly 
employees (collectively, the “Retirement Plans”) are based upon years of service and average compensation for the 
highest 60 consecutive months of the employee’s last 120 months of service, as defined. Each plan covers substantially all 
full-time employees hired before May 1, 2001. Ciner Corp’s pension plans had a net unfunded liability balance of $56,883 
and $57,370 at December 31, 2018 and December 31, 2017, respectively. Ciner Corp’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 the pension plans' net periodic pension costs was $412, $1,358 and $2,015 for the years ended 
December 31, 2018, 2017 and 2016, respectively. The decrease in pension costs in 2018 was driven by reduced service 
costs from retirements and asset gains from the prior year.

Savings Plan - The 401(k) retirement plan (the “401(k) Plan”) covers all eligible hourly and salaried employees. 
Eligibility is limited to all domestic residents and any foreign expatriates who are in the United States indefinitely. The 
plan permits employees to contribute specified percentages of their compensation, while the Company makes 
contributions based upon specified percentages of employee contributions. Participants hired on or subsequent to May 1, 
2001, will receive an additional contribution from the Company based on a percentage of the participant’s base pay. 
Contributions made to the 401(k) Plan for the years ended December 31, 2018, 2017 and 2016 were $2,833, $3,735 and 
$1,625, respectively.  The decrease in 2018 was primarily due to the additional profit sharing contributions made during 
2017 that did not occur during the current year.

17

Postretirement Benefits - Most of the Company's employees are eligible for postretirement benefits other than pensions if 
they reach retirement age while still employed.

The postretirement benefits are accounted for by Ciner Corp on an accrual basis over an employee’s period of service. 
The postretirement plan, excluding pensions, are not funded, and Ciner Corp has the right to modify or terminate the plan. 
The post-retirement plan had a net unfunded liability of $9,851 and $11,465 for the years ended December 31, 2018 and 
2017, respectively. The decrease in the obligation as of December 31, 2018 as compared to December 31, 2017 is due to 
the Ciner Corp amending its postretirement benefit plan during 2017 to increase eligibility requirements at which 
participants may begin receiving benefits, implementing a subsidy rather than a premium for the benefit plan, and 
eliminating plan eligibility for individuals hired after December 31, 2016.  The result of these changes have resulted in a 
postretirement (benefit) cost being amortized to the liability recorded at Ciner Corp during the latter half of 2017 and into 
2018. The Company's allocated portion of postretirement (benefit) costs was $(2,940), $(2,823) and $1,400 for the years 
ended December 31, 2018, 2017 and 2016, respectively.  The postretirement benefit for the Company in 2018 and 2017 is 
due to the aforementioned changes made to the postretirement benefit plans during 2017.

Springs Royalty Company, LLC, an affiliate of Anadarko Petroleum, and other private parties. All of these leases and the 
license 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 license 
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 (“Watco”), 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 on 
land by which Watco holds an easement from 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. easement lease is perpetual. The 

19

Company has an option agreement with Watco to assign these leases to the Company at any time during the land lease 
term. An annual rental of $15 thousand is paid under the easement and an annual rental of $60 thousand is paid under the 
lease.

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, 2018, the total minimum rental commitments under the Company’s various operating leases, 
including renewal periods are as follows:

Ciner Corp 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. Ciner 
Corp's obligations related to these railcar leases are $11,131 in 2019, $8,511 in 2020, $5,953 in 2021, $3,805 in 2022, 
$1,421 in 2023 and $4,740 in 2024 and thereafter. Total lease expense allocated to the Company from Ciner Corp was 
approximately $13,919, $14,628 and $14,476 for the years ended December 31, 2018, 2017 and 2016, respectively, and is 
recorded in cost of products sold.  

Purchase Commitments - The Company has both physical and financial natural gas supply contracts to mitigate volatility 
in the price of natural gas. As of December 31, 2018, these contracts totaled $55,984 for the purchase of a portion of our 
gas requirements over approximately the next five years. The aggregate supply purchase agreements for both the physical 
and financial contracts have specific commitments of $21,277 in 2019, $15,728 in 2020, $9,974 in 2021, $4,987 in 2022 
and $3,874 in 2023. The Company has a separate contract that expires in 2021, for transportation of natural gas with an 
average annual cost of approximately $3,823 per year.

Legal and Environmental - From time to time we are party to various claims and legal proceedings related to our business. 
Although the outcome of these proceedings cannot be predicted with certainty, management does not currently expect any 
of the legal proceedings we are involved in to have a material effect on our business, financial condition and results of 
operations. We cannot predict the nature of any future claims or proceedings, nor the ultimate size or outcome of existing 
claims and legal proceedings and whether any damages resulting from them will be covered by insurance.

Litigation Settlement- On February 2, 2016, amended on January 3, 2017, Ciner Wyoming filed suit against Rock Springs 
Royalty Company, LLC (“RSRC”) in the Third Judicial District Court in Sweetwater County, Wyoming, Case No. 
C-16-77-L, seeking, among other things, to recover approximately $32,000 in royalty overpayments.  The royalty 
payments arose under our license with RSRC, an affiliate of Anardarko Petroleum Corporation, to mine sodium minerals 
from lands located in Sweetwater County, Wyoming (“License”). The License sets the applicable royalty rate based on a 
most favored nation clause, where either the royalty rate is set at the same royalty rate we pay to other licensors in 
Sweetwater County for sodium minerals, or, if certain conditions are met, the royalty rate is set by the rate paid by a third 
party to Anadarko Petroleum Corporation under a separate license. In the lawsuit, we claim that RSRC has, for at least the 
last ten years, been charging an arbitrarily high royalty rate in contradiction of the License terms. In addition, we sought a 
modification of the expiration term of the License land-lease between Ciner Wyoming and RSRC to those terms granted 
to other licensors in accordance with the most favored nation clause. 

20

On June 28, 2018, RSRC and Ciner Wyoming signed a Settlement Agreement and Release (the “Settlement Agreement”) 
which among other things (i) required RSRC to pay Ciner Wyoming $27,500 which was received on July 2, 2018, and (ii) 
concurrently amended selected sections of the License land-lease including among other things, (a) extension of the term 
of the License Agreement to July 18, 2061 and for so long thereafter as Ciner Wyoming continuously conducts operations 
to mine and remove sodium minerals from the licensed premises in commercial quantities; and (b) revises the production 
royalty rate for each sale of sodium mineral products produced from ore extracted from the licensed premises at the 
royalty rate of eight percent (8%) of the sale price of such sodium mineral products. There are no unresolved conditions or 
uncertainties associated with the Settlement Agreement and management determined the $27,500 settlement payment was 
related to the historical overpayment of royalties. 

Off-Balance Sheet Arrangements - We have a self-bond agreement with the Wyoming Department of Environmental 
Quality under which we commit to pay directly for reclamation costs at our Green River, Wyoming plant site. The amount 
of the bond was $32,900 as of December 31, 2018 and December 31, 2017, which is the amount we would need to pay 
the State of Wyoming for reclamation costs if we cease mining operations currently. The amount of this self-bond is 
subject to change upon periodic re-evaluation by the Land Quality Division. 

13. AFFILIATES TRANSACTIONS

Ciner Corp is the exclusive sales agent for the Company and through its membership in ANSAC, Ciner Corp is 
responsible for promoting and increasing the use and sale of soda ash and other refined or processed sodium products 
produced. 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. On 
November 9, 2018, Ciner Corp delivered a notice to terminate its membership in ANSAC. The termination from ANSAC 
will be effective as of December 31, 2021. As of December 31, 2018, we have not recognized an asset or liability related 
to its exit from ANSAC as such an amount is not currently probable or estimable. 

All actual sales and marketing costs incurred by Ciner Corp are charged directly to the Company. Selling, general and 
administrative expenses also include amounts charged to the Company by Ciner Corp principally consisting of salaries, 
benefits, office supplies, professional fees, travel, rent and other costs of certain assets used by the Company. Ciner Corp 
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 Ciner Corp an annual management fee and reimburse Ciner Corp 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, Ciner Corp, 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. There were no sales to CIDT during the twelve months ended December 31, 2018, as the previous 
contract concluded in the 2017 year.

(1) ANSAC allocates its expenses to its members using a pro rata calculation based on sales.

Cost of products sold includes an allocation of Ciner Corp's railcar lease expense (refer to Note 12) and logistics services 
charged by ANSAC. These ANSAC logistics costs were $0, $19,573 and $3,278 for the years ended December 31, 2018, 
2017 and 2016, respectively. When we elect to use ANSAC to provide freight services for our other non-ANSAC 
international sales, ANSAC separately and directly charges the Company for such services. During the year ended 2018 
we did not use ANSAC for non-ANSAC international sales. The decrease in freight costs charged by ANSAC was due to 
a decrease in non-ANSAC international sales, to CIDT, during the year ended December 31, 2018 compared to 2017. 
There were no sales to CIDT during the year ended December 31, 2018, as the previous contract concluded in the 2017 
year.

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, 2018, 
2017 and 2016 are as follows:

15. REVENUE

The Company has one reportable segment and our revenue is derived from the sale of soda ash which is our sole and 
primary good and service. We account for revenue in accordance with ASC 606, Revenue from Contracts with 
Customers, which we adopted on January 1, 2018, using the modified retrospective method.

Performance Obligations. A performance obligation is a promise in a contract to transfer a distinct good or service to the 
customer, and is the unit of account in ASC 606. A contract’s transaction price is allocated to each distinct performance 
obligation and recognized as revenue when, or as, the performance obligation is satisfied. At contract inception, we assess 
the goods and services promised in contracts with customers and identify performance obligations for each promise to 
transfer to the customer, a good or service that is distinct.  To identify the performance obligations, the Company 
considers all goods and services promised in the contract regardless of whether they are explicitly stated or are implied by 
customary business practices.  From its analysis, the Company determined that the sale of soda ash is currently its only 
performance obligation. Many of our customer volume commitments are short-term and our performance obligations for 
the sale of soda ash are generally limited to single purchase orders.

When performance obligations are satisfied. Substantially all of our revenue is recognized at a point-in-time 
when control of goods transfers to the customer.

Transfer of Goods. The Company uses standard shipping terms across each customer contract with very few 
exceptions.  Shipments to customers are made with terms stated as Free on Board (“FOB”) Shipping Point.  
Control typically transfers when goods are delivered to the carrier for shipment, which is the point at which the 
customer has the ability to direct the use of and obtain substantially all remaining benefits from the asset.

Payment Terms. Our payment terms vary by the type and location of our customers. The term between invoicing 
and when payment is due is not significant and consistent with typical terms in the industry.

Variable Consideration. We recognize revenue as the amount of consideration that we expect to receive in 
exchange for transferring promised goods or services to customers.  We do not adjust the transaction price for the 
effects of a significant financing component, as the time period between control transfer of goods and services 
and expected payment is one year or less.  At the time of sale, we estimate provisions for different forms of 
variable consideration (discounts, rebates, and pricing adjustments) based on historical experience, current 
conditions and contractual obligations, as applicable.  The estimated transaction price is typically not subject to 
significant reversals.  We adjust these estimates when the most likely amount of consideration we expect to 
receive changes, although these changes are typically immaterial.

Returns, Refunds and Warranties. In the normal course of business, the Company does not accept returns, nor 
does it typically provide customers with the right to a refund.

Freight. In accordance with ASC 606, the Company made a policy election to treat freight and related costs that 
occur after control of the related good transfers to the customer as fulfillment activities instead of separate 
performance obligations. Therefore freight is recognized at the point in which control of soda ash has transferred 
to the customer.

Revenue disaggregation. In accordance with ASC 606-10-50, the Company disaggregates revenue from contracts with 
customers into geographical regions.  The Company determined that disaggregating revenue into these categories 
achieved the disclosure objectives to depict how the nature, timing, amount and uncertainty of revenue and cash flows are 
affected by economic factors.  Refer to Note 14, “Major Customers and Segment Reporting” for revenue disaggregated 
into geographical regions.

23

Contract Balances. The timing of revenue recognition, billings and cash collections results in billed receivables, unbilled 
receivables (contract assets), and customer advances and deposits (contract liabilities).

Contract Assets. At the point of shipping, the Company has an unconditional right to payment that is only 
dependent on the passage of time. In general, customers are billed and a receivable is recorded as goods are 
shipped. These billed receivables are reported as “Accounts Receivable, net” on the Balance Sheet as of 
December 31, 2018. There were no contract assets as of December 31, 2018 or as of the date of adoption of ASC 
606.

Contract Liabilities. There may be situations where customers are required to prepay for freight and insurance 
prior to shipment.  The Company has elected the practical expedient for its treatment of freight and therefore, 
such prepayments are considered a part of the single obligation to provide soda ash.   In such instances, a 
contract liability for prepaid freight will be recorded.  For the twelve months ended December 31, 2018, there 
were no customers that required prepaid freight. There were no contract liabilities as of December 31, 2018 or as 
of the date of adoption of ASC 606.

Practical and Expedients Exceptions

Incremental costs of obtaining contracts. We generally expense costs related to sales, including sales force salaries and 
marketing expenses, when incurred because the amortization period would have been one year or less. These costs are 
recorded within sales and marketing expenses.

Unsatisfied performance obligations. We do not disclose the value of unsatisfied performance obligations for contracts 
with an original expected length of one year or less.

16. SUBSEQUENT EVENTS

On February 14, 2019, the members of the Board of Managers of Ciner Wyoming, approved a cash distribution to the 
members of Ciner Wyoming in the aggregate amount of $20,000. This distribution was payable and paid on February 15, 
2019.
