for NRP in 2017 and beyond.”

To Our Unitholders,

Although 2016 was another extremely challenging year for the energy 
industry, the coal markets and industry sentiment began to improve in the 
fourth quarter and, as a result of the successful execution of our long-term 
deleveraging strategy, NRP entered 2017 as a much stronger company that 
is well-positioned for the future. The royalty nature of our coal business, 
combined with the steady performance of our diversified platform of 
assets in the soda ash and aggregates industries, enabled us to navigate 
one of the toughest extended energy markets in decades. 

The stock market took notice of our accomplishments, as our unit price nearly tripled 

during 2016. Further, our disciplined capital approach led to the recent consummation  

of multiple transactions that recapitalized and deleveraged the company and extended 

our debt maturities. These transactions mark the beginning of a new era for NRP,  

but as we look to the future, we will continue our focus on strengthening our balance 

sheet and enhancing our liquidity. We believe that this strategy will create value for  

all of our stakeholders.

2016 Accomplishments

In spite of the difficult energy markets, 2016 was marked by a number of successful 

accomplishments that set the stage for our recapitalization transactions and have  

re-positioned NRP for the future. Among our more noteworthy achievements, we:

» Consummated asset sales generating gross proceeds of $181 million that enhanced 

liquidity and accelerated our deleveraging;

» Reduced our debt by $248 million;

» Sustained our quarterly distribution to unitholders at $0.45 per unit;

» Continued our focus on reducing costs across all of our business segments;

» Through our governance and ownership of our soda ash business, assured  

$46.6 million of cash distributions; and

» Recorded the second best year in terms of reportable injuries in VantaCore’s history.

As a result of our efforts, both our unit and bond prices improved dramatically over the 

course of the year, and we created the opportunity to structure a longer-term solution. 

“Between January 1, 2016 
and April 3, 2017, we 
have reduced debt by 
$484 million and extended 
the maturities of both our 
bonds and credit facility.”

“The last two years have

everyone in the coal 
and energy markets, 
but NRP has emerged 
from these difficult times 
as a stronger company 
that is well-positioned 
to take advantage 
of opportunities and 
create value for 
our stakeholders.”

Summary of Recapitalization Transactions

In March 2017, we completed a series of transactions in order to strengthen our  

balance sheet, enhance our liquidity and reposition the partnership for long-term  

growth, including:

» The issuance of $250 million of a new class of 12.0% preferred units, together with 

warrants to purchase common units, to certain entities controlled by funds affiliated 

with The Blackstone Group, L.P. and affiliates of GoldenTree Asset Management LP;

» The exchange of $241 million of our 9.125% Senior Notes due 2018  

(the “2018 Notes”) for $241 million of a new series of 10.500% Senior Notes  

due 2022 (the “2022 Notes”), and the sale of $105 million of additional  

2022 Notes in exchange for cash proceeds; and

» The extension of Opco’s revolving credit facility to April 2020, with commitments 

thereunder reduced to $180 million.

We used the proceeds from these transactions to pay off the full $210 million balance 

on Opco’s revolving credit facility and redeem $90 million of the remaining 2018 Notes. 

Additionally, we paid $41 million in principal on the Opco Notes in the first quarter  

of 2017. After accounting for the issuance of $105 million of additional 2022 notes 

described above, we have reduced our debt by an additional $236 million since the  

end of 2016.

Looking Ahead – A New Era

Our recent transactions provided us with substantial liquidity, improved our balance 

sheet and also brought in a new strategic partner in Blackstone. Between January 1, 2016 

and April 3, 2017, we have reduced debt by $484 million and extended the maturities 

of both our bonds and credit facility. As we look ahead, we will continue to focus on 

our balance sheet, but will also be exploring new opportunities to grow. The recent 

improvements in the markets for both metallurgical and thermal coal, combined with 

the balance and diversification of our soda ash and aggregates businesses, position 

NRP well for the future. 

The last two years have been challenging for everyone in the coal and energy markets, 

but NRP has emerged from these difficult times as a stronger company that is well- 

positioned to take advantage of opportunities and create value for our stakeholders. 

We are looking forward to a new era for NRP in 2017 and beyond.

ITEMS 1. AND 2.  BUSINESS AND PROPERTIES 

Partnership Structure and Management

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

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

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

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

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

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  Investor  Rights  Agreement  with  Adena  Minerals,  LLC  ("Adena  Minerals")  and  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 is entitled to nominate eleven directors to the Board of Directors of GP Natural Resource Partners 
LLC. Mr. Robertson has delegated the right to nominate two of the directors, one of whom must be independent, to Adena Minerals, 
and one director to Blackstone.

The  senior  executives  and  other  officers  who  manage  NRP  are  employees  of  Western  Pocahontas  Properties  Limited 
Partnership and Quintana Minerals Corporation, companies controlled by Mr. Robertson, and they 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.

2017 Recapitalization Transactions

On March 2, 2017, we completed a series of transactions in order to strengthen our balance sheet, enhance our liquidity 

and ultimately reposition the partnership for long-term growth, including:  

• 

• 

the issuance of $250 million of a new class of 12.0% preferred units representing limited partner interests in NRP, 
together with warrants to purchase common units, to Blackstone and GoldenTree;

the exchange of $241 million of our 9.125% Senior Notes due 2018 (the "2018 Notes") for $241 million of a new 
series of 10.500% Senior Notes due 2022 (the "2022 Notes"), and the sale of $105 million of additional 2022 Notes 
in exchange for cash proceeds; and

• 

the extension of Opco’s revolving credit facility to April 2020, with commitments thereunder reduced to $180 million.  

We used a portion of the proceeds from these transactions to repay Opco’s revolving credit facility in full and pay all fees 
and expenses associated with the transactions described above. We will also use a portion of the proceeds to redeem the remaining 
2018 Notes.  On March 3, 2017, we delivered a notice of partial redemption for $90.0 million of our outstanding 2018 Notes at a 
redemption price of 104.563%, plus accrued and unpaid interest to the redemption date. This partial redemption of the 2018 Notes 
is expected to occur on April 3, 2017.  We will redeem all of the remaining 2018 Notes within 60 days after October 1, 2017 at 
the then-applicable price and pay all accrued and unpaid interest thereon.  For more information on these transactions, including 
the terms of the preferred units, warrants and 2022 Notes, see "Management’s Discussion and Analysis of Financial Condition 
and Results of Operations—Liquidity and Capital Resources—2017 Recapitalization Transactions."

2016 Asset Sales

Prior to completion of the recapitalization transactions discussed above, we had been pursuing or considering a number of 
actions,  including  dispositions  of  assets,  in  order  to  mitigate  the  effects  of  adverse  market  developments  and  scheduled  debt 
principal payments.  As part of this plan, we sold assets during the year ended December 31, 2016, for total gross proceeds of 
$181.0 million that consisted of the following:

1)  Oil and gas working interest in the Williston Basin for $116.1 million gross sales proceeds. Our exit from the non-operated 
oil and gas working interest business represented a strategic shift to reduce debt and focus on our coal royalty, soda ash and 
construction aggregates business segments. 

2)  Oil and gas royalty and overriding royalty interests in several producing properties located in the Appalachian Basin for 

$36.4 million gross sales proceeds. 

3)  Aggregates reserves and related royalty rights at three aggregates operations located in Texas, Georgia and Tennessee for 

$10.0 million gross sales proceeds. 

4)  Mineral  reserves  in  multiple  sale  transactions  for  cumulative  $17.3  million  of  gross  sales  proceeds. These  amounts 
primarily relate to eminent domain transactions with governmental agencies and the sale of additional oil and gas royalty interests. 
Additional asset sales during the year included sales of land and plant and equipment for $1.2 million of gross proceeds.

Segment and Geographic Information

The amount of total revenue for each of our operating segments in the last three years is shown below (dollars in thousands). 
For additional operating segment information, please see "Note 4. Segment Information" in the Notes to Consolidated Financial 
Statements under Item 8 in this Annual Report on Form 10-K and "Management's Discussion and Analysis of Financial Condition

We do not operate any coal mines, but lease our reserves to experienced mine operators under long-term leases that grant 
the operators the right to mine and sell our reserves in exchange for royalty payments. A typical lease has a five- to ten-year base 
term, with the lessee having an option to extend the lease for additional terms. Leases may include the right to renegotiate rents 
and royalties for the extended term. We also own and manage coal related infrastructure assets that generate additional revenues 
in the Illinois Basin. In addition, we own aggregates and industrial mineral reserves located in a number of states across the country. 
We derive a small percentage of our aggregates and industrial mineral revenues by leasing our owned reserves to third party 
operators who mine and sell the reserves in exchange for royalty payments. 

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

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

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

(1)  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 for Illinois (typically 12% 
moisture) and Northern Powder River Basin (typically 25%).

(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.

(3)  For purposes of this table, we have defined metallurgical coal reserves as reserves located in those seams that historically 
have been of sufficient quality and characteristics to be able to be used in the steel making process. Some of the reserves 
in the metallurgical category can also be used as steam coal. In 2016, approximately 37% of our coal royalty revenues and 
approximately 35% of the related production from metallurgical coal. In prior years metallurgical coal royalty revenues 
accounted for a greater portion of total revenue when compared to the proportion of total production.  In 2016, pricing for 
metallurgical coal was comparable to thermal coal pricing.

Methodologies Used in Mineral Reserve Estimation

All of the reserves reported above are recoverable proved or probable reserves as determined by the SEC’s Industry Guide 
7 and are estimated by our internal reserve engineers. The technologies and economic data used by our internal reserve engineers 
in the estimation of our proved 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."

Illinois Basin

Williamson.    The Williamson property is located in Franklin and Williamson Counties, Illinois. The property is under lease 
to a subsidiary of Foresight Energy LP, and in 2016, approximately 5.0 million tons were mined on the property. This production 
is from a longwall mine and is shipped primarily via the Canadian National railroad to domestic utility customers and to various 
export customers.

Macoupin.    The Macoupin property is located in Macoupin County, Illinois. The property is under lease to a subsidiary of 
Foresight Energy LP, and in 2016, approximately 2.1 million tons were shipped from the property. Production is from an underground 
mine and is shipped via the Norfolk Southern or Union Pacific railroads or by barge to utility customers such or loaded into barges 
for shipment to export customers.

Hillsboro/Deer Run.    The Hillsboro property is located in Montgomery and Bond Counties, Illinois. The property is under 
lease to a subsidiary of Foresight Energy, and in 2016, approximately 0.1 million tons were shipped from the property. When 
active, production at the Deer Run mine on our Hillsboro property is from an underground longwall mine and is shipped via either 
the Union Pacific, Norfolk Southern or Canadian National railroads or by barges to domestic utilities or export customers. The 
Deer Run mine has been idled since March 2015 as a result of elevated carbon monoxide levels in the mine. In July 2015, we 
received a notice from Foresight Energy declaring a force majeure event at the mine as a result of the elevated carbon monoxide 
levels. We believe Foresight's claim of force majeure has no merit, and we are vigorously pursuing our claims against them through 
a lawsuit that we filed in November 2015. However, the effect of a valid force majeure declaration would relieve Foresight Energy 
of its obligation to pay us minimum deficiency payments of $7.5 million per quarter, or $30.0 million per year. For more information 
on the idling of the Deer Run mine, see "Item 3. Legal Proceedings" included elsewhere in this Annual Report on Form 10-K. 

In addition to these properties, we own loadout and other transportation assets at the Williamson and Macoupin mines and 
at the Sugar Camp mine, which is another mine operated by Foresight Energy. See "—Coal Transportation and Processing Assets."

Northern Powder River Basin

Western  Energy.    The  Western  Energy  property  is  located  in  Rosebud  and  Treasure  Counties,  Montana.  In  2016, 
approximately 3.8 million tons were produced from our property by a subsidiary of Westmoreland Coal Company. Coal is produced 
by surface dragline mining, and the coal is transported by either truck or beltline to the four-unit 2,200-megawatt Colstrip generation 
station located at the mine mouth. 

The map below shows the location of our property in the Northern Powder River Basin:

Coal Transportation and Processing Assets

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

12

Other Assets

As of December 31, 2016, we owned an estimated 250 million tons of aggregates reserves primarily located in Kentucky, 
Washington and Indiana. We lease a portion of these reserves to third parties in exchange for royalty payments. We also lease 
approximately 90 million tons of these reserves to VantaCore's Grand Rivers operation. The structure of these leases is similar to 
our coal leases, and these leases typically also require minimum rental payments in addition to royalties. During 2016, our aggregates 
lessees produced 1.5 million tons of aggregates from these properties and we received $3.2 million in aggregates royalty revenues, 
including overriding royalty revenues. 

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

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

• 

• 

• 

• 

• 

approximately 300,000 gross acres of oil and gas mineral rights in Louisiana, of which over 53,000 acres 
were leased as of December 31, 2016; 

approximately 95,000 net mineral acres of coal rights (primarily lignite and some bituminous coal) in the 
Gulf Coast region, of which approximately 4,800 acres are leased in Louisiana, Alabama and Texas;

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

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

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

While the vast majority of the 10 million acres remain largely undeveloped, BRP has an ongoing program to identify additional 
opportunities to lease its minerals to operating parties.

Soda Ash Segment 

We own a 49% non-controlling equity interest in Ciner Wyoming, which 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 six large continuous mining machines and ten underground shuttle cars in its mining operations. 
Its  processing  assets  consist  of  material  sizing  units,  conveyors,  calciners,  dissolver  circuits,  thickener  tanks,  drum  filters, 
evaporators and rotary dryers. The following map provides an aerial  overview of Ciner Wyoming’s surface operations:

13

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

Deca Rehydration.  The evaporation stage of trona ore processing produces a precipitate and natural by-product called deca. 
"Deca," short for sodium carbonate decahydrate, is one part soda ash and ten parts water. Solar evaporation causes deca to crystallize 
and precipitate to the bottom of the four main surface ponds at the Green River Basin facility. Ciner Wyoming’s 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 
14

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

Shipping and Logistics.  All of the soda ash produced is shipped by rail or truck from the Green River Basin facility. For the 
year ended December 31, 2016, Ciner Wyoming shipped approximately 96% of its soda ash to customers initially via rail under 
a contract with Union Pacific that expires on December 31, 2017, and the plant receives rail service exclusively from Union Pacific. 
Ciner Wyoming leases a fleet of more than 2,000 hopper cars that serve as dedicated modes of shipment to its domestic customers. 
For export, Ciner Wyoming ships soda ash on unit trains consisting of approximately 100 cars to two primary ports: Port Arthur, 
Texas and Portland, Oregon. From these ports, the soda ash is loaded onto ships for delivery to ports all over the world. American 
Natural Soda Ash Corporation ("ANSAC") provides logistics and support services for all of Ciner Wyoming’s export sales. For 
domestic sales, Ciner Resources Corporation provides similar services.

Customers.  Ciner Wyoming’s largest customer is ANSAC, which buys soda ash (through Ciner Wyoming’s sales agent) and 
other of its member companies for further export to its customers. ANSAC accounted for approximately 55% of Ciner Wyoming’s 
net sales in 2016. 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. 

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

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

VantaCore Segment  

VantaCore is a construction materials company that we acquired on October 1, 2014. VantaCore operates four limestone 
quarries, one underground limestone mine, five sand and gravel plants, two asphalt plants and two marine terminals. VantaCore 
is headquartered in Philadelphia, Pennsylvania, and its operations are located in Pennsylvania, West Virginia, Tennessee, Kentucky 
and Louisiana. As of December 31, 2016, VantaCore controlled approximately 400 million tons of estimated aggregates reserves, 
including  approximately  117  million  tons  of  reserves  leased  at  the  Grand  Rivers  operation  from  the  Coal  Royalty  and  Other 
segment. The reserve estimates for each of VantaCore’s properties were prepared internally and audited by an independent third 
party advisor. For the year ended December 31, 2016, VantaCore sold approximately 5.5 million tons of crushed stone and gravel, 
including brokered stone, 1.2 million tons of sand and 0.2 million tons of asphalt. VantaCore’s four operating businesses are Laurel 
Aggregates, located in Lake Lynn, Pennsylvania, Winn Materials/McIntosh Construction, located in Clarksville, Tennessee, Grand 
Rivers, located in Grand Rivers, Kentucky and Southern Aggregates, located near Baton Rouge, Louisiana. VantaCore’s business 
is seasonal, with production typically lower in the first quarter of each year due to winter weather. The following map shows the 
locations of each of VantaCore’s operations.

15

Laurel Aggregates

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

Winn Materials/McIntosh Construction

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

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

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

16

Grand Rivers

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

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

Southern Aggregates

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

Significant Customers

We have a significant concentration of revenues with Foresight Energy and its subsidiaries, with total revenues of $63.4 
million in 2016. The exposure is spread out over four different mining operations. We are currently in disputes with and have filed 
two separate lawsuits against two of Foresight Energy's subsidiaries, Hillsboro Energy for breach of contract due to wrongful 
declaration of force majeure at the Deer Run mine, and Macoupin Energy for breach of contract for wrongful recoupment of 
previously paid minimum royalties. For additional information on the Deer Run mine lawsuit, see Note 15. "Major Customers"
in the Notes to Consolidated Financial Statements under "Item 8. Financial Statements and Supplementary Data" and "Item 3. 
Legal Proceedings" included elsewhere in this Annual Report on Form 10-K.

Competition

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

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

Our trona mining and soda ash refinery business in the Green River Basin, Wyoming, 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 

17

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 a significant percentage of our coal and aggregates reserves in fee as of December 31, 2016. We lease the remainder 
from  unaffiliated  third  parties,  including  leasing  aggregates  reserves  for  VantaCore’s  construction  materials  business.  Ciner 
Wyoming also leases or licenses its trona reserves. We believe that we have satisfactory title to all of our mineral properties, but 
we have not had a qualified title company confirm this belief. Although title to these properties is subject to encumbrances in 
certain cases, such as customary easements, rights-of-way, interests generally retained in connection with the acquisition of real 
property, licenses, prior reservations, leases, liens, restrictions and other encumbrances, we believe that none of these burdens will 
materially detract from the value of our properties or from our interest in them or will materially interfere with their use in the 
operation of our business.

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

Regulation and Environmental Matters

General

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

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

In addition, the electric utility industry, which is the most significant end-user of steam 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.

18

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

Air Emissions

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

Carbon Dioxide and Greenhouse Gas Emissions

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

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

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

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. Prior to taking office, President 
Trump expressed his desire that the United States withdraw from the Paris Climate Agreement.

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

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

19

Hazardous Materials and Waste

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

Water Discharges

Operations conducted on our properties can result in discharges of pollutants into waters. The Clean Water Act and analogous 
state laws and regulations create two permitting programs for mining operations. The National Pollutant Discharge Elimination 
System (NPDES) program under Section 402 of the statute is administered by the states or EPA and regulates the concentrations 
of pollutants in discharges of waste and storm water from a mine site. The Section 404 program is administered by the Army Corps 
of Engineers and regulates the placement of overburden and fill material into channels, streams and wetlands that comprise "waters 
of the United States." The scope of waters that may fall within the jurisdictional reach of the Clean Water Act is expansive and 
may include land features not commonly understood to be a stream or wetlands.  In June 2015, EPA issued a new rule defining 
the scope of "Waters of the United States" (WOTUS) that are subject to regulation.  The WOTUS rule has been challenged by a 
number of states and private parties and was stayed on a nationwide basis by the Sixth Circuit Court of Appeals in October 2015. 
In February 2016, the United States Court of Appeals for the Sixth Circuit ruled that it has exclusive jurisdiction over the challenge. 
In January 2017, the Supreme Court decided to hear a petition by industry groups challenging the Sixth Circuit’s jurisdictional 
determination. 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 EPA’s review of permits, it has 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. 
NRP has been named as a defendant in one of these lawsuits. 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. While it is too early to determine the merits or 
predict the outcome of any of these lawsuits, any determination that a landowner or lessee has liability for discharges from a 
previously reclaimed mine site could result in substantial compliance costs or fines and would result in uncertainty as to continuing 
liability for completed and reclaimed coal mine operations.

Other Regulations Affecting the Mining Industry

Mine Health and Safety Laws

The operations of our lessees, VantaCore 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. Regulatory authorities or individual citizens who bring 
civil actions under SMCRA may attempt to assign the liabilities of our coal lessees to us if any of these lessees are not financially 
capable of fulfilling those obligations.

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.

Regulations under SMCRA include a "stream buffer zone" rule that prohibits certain mining activities near streams. In 2008, 
the federal Office of Surface Mining (OSM), which implements SMCRA, revised the stream buffer zone rule, making it more 
clear that valley fills are not prohibited by the rule. Environmental groups challenged the revision to the buffer zone rule in federal 
court. In February 2014, the federal court vacated the 2008 rule and in December 2014, OSM reinstated the previous version of 
the rule, without clarifying whether the previous version of the rule impacts the ability to construct excess fills. In December 2016, 
OSM finalized the "Stream Protection Rule," a re-written version of the stream buffer zone rule which requires coal operators to 

21

restrict mining within 100 feet of waterways. The rule also requires states to impose additional information gathering and monitoring 
at and around coal mining sites and mandates new financial assurance and reclamation requirements. The rule was repealed by 
Congress in February 2017; however, to the extent the rule is ever reinstated, it could restrict our lessees’ ability to develop new 
mines, or could require our lessees to modify existing operations, which could have an adverse effect on our coal-related revenues.

Employees and Labor Relations

As of January 31, 2017, affiliates of our general partner employed 63 people who directly supported our operations. None 
of  these  employees  were  subject  to  a  collective  bargaining  agreement. We  employed  221  people  who  supported VantaCore’s 
construction  aggregates  mining  and  production  operations.  None  of  these  employees  were  subject  to  a  collective  bargaining 
agreement.

ITEM 1A.  

RISK FACTORS 

Risks Related to Our Business 

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

Because distributions on the common units are dependent on the amount of cash we generate, distributions fluctuate based 
on our performance. The actual amount of cash that is available to be distributed each quarter depends on numerous factors, some 
of which are beyond our control and the control of the general partner. 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. 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. Following the recapitalization transactions, we still have significant debt service obligations 
and obligations to pay cash distributions on our preferred units. To the extent our board of directors deems appropriate, it may 
determine to decrease the amount of the quarterly distribution on our common units or suspend or eliminate the distribution on 
our common units altogether. In addition, because our unitholders are required to pay income taxes on their respective shares of 
our taxable income, you may be required to pay taxes in excess of any future distributions we make. Your share of our portfolio 
income may be taxable to you even though you receive other losses from our activities.  See "—Tax Risks to Common Unitholders
—You are required to pay taxes on your share of our income even if you do not receive any cash distributions from us." 

The agreements governing our indebtedness and preferred units restrict our ability to raise, and in some cases continue to 
pay, distributions on our common units. Opco’s revolving credit agreement, the indenture governing our 2022 Notes and our 
partnership agreement each require that we meet certain consolidated leverage tests in order to raise our quarterly distribution on 
the common units above the current level of $0.45 per quarter. The maximum leverage covenant under Opco’s revolving credit 
facility will step down permanently from 4.0x to 3.0x if we increase the common unit distribution above the current level. In 
addition, under our partnership agreement, to the extent we have paid any distributions on the preferred units in kind ("PIK units"), 
and such PIK units are still outstanding at any time after January 1, 2022, we will be prohibited from making any distributions 
with respect to our common units until we have redeemed all such PIK units in cash. For more information on restrictions on our 
ability to make distributions on our common units, see "Management’s Discussion and Analysis of Financial Condition and Results 
of Operations—Liquidity and Capital Resources—2017 Recapitalization Transactions" and "Item 8. Financial Statements and 
Supplementary Data—Note 11. Debt and Debt—Affiliate."

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

As  of  December 31,  2016,  we  and  our  subsidiaries  had  approximately  $1.1  billion  of  total  indebtedness.  Following  the 
execution of our recapitalization transactions, we and our subsidiaries had approximately $944 million of total indebtedness. The 
terms and conditions governing our indebtedness, including the indentures for NRP’s 2018 Notes and 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;

23

• 

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

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

on our debt obligations; and

• 

limit management’s discretion in operating our business.

Our ability to meet our expenses and debt obligations will depend on our future performance, which will be affected by 
financial, business, economic, regulatory and other factors. We will not be able to control many of these factors, such as economic 
conditions and governmental regulation. We cannot be certain that our cash flow will be sufficient to allow us to pay the principal 
and interest on our debt and meet our other obligations, including payment of distributions on the preferred units. If we do not 
have sufficient funds, we may be required to refinance all or part of our existing debt, borrow more money, or sell assets or raise 
equity at unattractive prices. We are required to make substantial principal repayments each year in connection with Opco’s senior 
notes, with approximately $81 million due thereunder each year through 2018. While we intend to make these payments using 
cash from operations, 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.

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

Foresight Energy is our largest lessee, and in 2016, we derived approximately 16% of our revenues from them. We are 
currently in disputes with them with respect to two of their four mining operations in which we have an interest. Foresight Energy’s 
Deer Run mine (which we also refer to as our Hillsboro property) has been idled for almost two years as a result of elevated carbon 
monoxide levels at the mine. Foresight Energy has declared a force majeure event at the Deer Run mine and failed to make $46.0 
million in required minimum deficiency payments to us as of the date hereof. Such amount is expected to increase by $7.5 million 
for each quarter during which mining operations continue to be idled. We have filed a lawsuit against Foresight Energy and Hillsboro 
Energy to recover the amounts owed to us and compel them to make the required minimum deficiency payments under the lease. 
We do not currently have an estimate as to when the mine will resume coal production. If the mine remains idled for an extended 
period or if the mine is permanently closed, our financial condition could be adversely affected. In addition, we have also filed a 
lawsuit against Foresight Energy’s Macoupin subsidiary, which has failed to comply with the terms of the coal mining, rail loadout 
and rail loop leases at the Macoupin mine by incorrectly recouping previously paid minimum royalties, resulting in a cumulative $6.2 
million negative cash impact to us.  See "Item 3. Legal Proceedings" included elsewhere in this Annual Report on Form 10-K for 
more information on our lawsuits against Foresight Energy. These ongoing disputes and further deterioration of our relationship 
with our largest lessee could have a material adverse effect on our financial condition and results of operations.  

Depressed coal prices have negatively affected our coal-related revenues and the value of our coal reserves. Further declines 
or a continued low price environment could have an additional adverse effect on our coal-related revenues and the value of 
our coal reserves.

Prices for both steam and metallurgical coal have declined substantially in recent years.  Steam coal prices remain at levels 
close to or below the level of operating costs for a number of our lessees. While metallurgical coal prices have improved in recent 
months, we do not expect the current pricing environment to be sustained, and prices could decline substantially.  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 and the demand for steel;

24

• 

the proximity to and capacity of transportation facilities;

•  weather conditions; and

• 

the effect of worldwide energy conservation measures.

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

Prices for metallurgical coal reached multi-year lows during 2016 due to global economic conditions. While metallurgical 
coal prices have improved in recent months, we do not expect the current pricing environment to be sustained. Our lessees produce 
a significant amount of the metallurgical coal that is used in both the U.S. and foreign steel industries. Since the amount of steel 
that is produced is tied to global economic conditions, a continuation of current conditions or a further decline in those conditions 
could result in the decline of steel, coke and metallurgical coal production. In addition, rising exports of metallurgical coal from 
Australia and a strong U.S. dollar continue to have a negative effect on prices received for metallurgical coal produced in the 
United States. Since metallurgical coal is priced higher than steam 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. In addition, during 2015 and 2016, a number of coal producers 
filed for protection under U.S. bankruptcy laws, including several of our coal lessees. Although many of our lessees have emerged 
from bankruptcies, 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.

Lower prices reduce the quantity of coal that may be economically produced from our properties, which in turn reduces our 
coal-related revenues and the value of our coal reserves. Further declines or a continued low price environment could have an 
additional adverse effect on our coal-related revenues or the value of our reserves. A long term asset generally is deemed impaired 
when the future expected cash flow from its use and disposition is less than its book value. Future impairment analyses could result 
in additional downward adjustments to the carrying value of our assets.

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

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

• 

• 

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

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

•  mining and processing equipment failures and unexpected maintenance problems;

• 

• 

• 

• 

• 

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

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

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

labor-related interruptions; and

unexpected mine safety accidents, including fires and explosions.

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

25

VantaCore currently operates four hard rock quarries, one underground limestone mine, six sand and gravel plants, two 
asphalt plants and two marine terminals. As an operator of these assets, we are exposed to risks that we have not historically been 
exposed to in our mineral rights and royalties business. Such risks include, but are not limited to, prices and demand for construction 
aggregates, capital and operating expenses necessary to maintain VantaCore’s operations, production levels, general economic 
conditions, conditions in the local markets that VantaCore serves, inclement or hazardous weather conditions and typically lower 
production levels in the winter months, permitting risk, fire, explosions or other accidents, and unanticipated geologic conditions. 
Any of these risks could result in damage to, or destruction of, VantaCore’s mining properties or production facilities, personal 
injury, environmental damage, delays in mining or processing, reduced revenue or losses or possible legal liability. In addition, 
not all of these risks are reasonably insurable, and our insurance coverage contains limits, deductibles, exclusions and endorsements. 
Our insurance coverage may not be sufficient to meet our needs in the event of loss. Any prolonged downtime or shutdowns at 
VantaCore’s mining properties or production facilities or material loss could have an adverse effect on our results of operations.

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

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

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

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

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

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

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

26

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.

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

New environmental legislation, new regulations and new interpretations of existing environmental laws, including regulations 
governing  permitting  requirements,  could  further  regulate  or  tax  the  mining  and  oil  and  gas industries  and  may  also  require 
significant changes to operations, the incurrence of increased costs or the requirement to obtain new or different permits, any of 
which could decrease our revenues and have a material adverse effect on our financial condition or results of operations.

In addition to governmental regulation, private citizens’ groups have continued to be active in bringing lawsuits against coal 
mine  operators  and  landowners.  Since  2012,  several  citizen  suit  group  lawsuits  have  been  filed  against  mine  operators  and 
landowners for alleged violations of water quality standards resulting from ongoing discharges of pollutants from reclaimed mining 
operations, including selenium and conductivity. NRP has been named as a defendant in one of these lawsuits. The citizen suit 
groups have sought penalties as well as injunctive relief that would limit future discharges of these pollutants, which would result 
in significant expenses for our lessees. While it is too early to determine the merits or measure the impact of these lawsuits, any 
determination that a landowner or lessee has liability for discharges from a previously reclaimed mine site would result in uncertainty 
as to continuing liability for completed and reclaimed coal mine operations and could result in substantial compliance costs or 
fines.

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

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

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

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

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

27

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

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

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

• 

the payment of minimum royalties;

•  marketing of the minerals mined;

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

• 

• 

• 

• 

• 

• 

• 

• 

• 

processing and blending minerals;

expansion plans and capital expenditures;

credit risk of their customers;

permitting;

insurance and surety bonding;

acquisition of surface rights and other mineral estates;

employee wages;

transportation arrangements;

compliance with applicable laws, including environmental laws; and

•  mine closure and reclamation.

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

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

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

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

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

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

28

face difficulties in the future that may impair the ability of our lessees to supply minerals to their customers, resulting in decreased 
royalty revenues to us.

In addition, Ciner Wyoming transports its soda ash by rail or truck and ocean vessel. As a result, its business and financial 
results are sensitive to increases in rail freight, trucking and ocean vessel rates. Increases in transportation costs, including increases 
resulting from emission control requirements, port taxes and fluctuations in the price of fuel, could make soda ash a less competitive 
product for glass manufacturers when compared to glass substitutes or recycled glass, or could make Ciner Wyoming’s soda ash 
less competitive than soda ash produced by competitors that have other means of transportation or are located closer to their 
customers. Ciner Wyoming may be unable to pass on its freight and other transportation costs in full because market prices for 
soda ash are generally determined by supply and demand forces. In addition, rail operations are subject to various risks that may 
result in a delay or lack of service at Ciner Wyoming’s facility, and alternative methods of transportation are impracticable or cost-
prohibitive. During 2016, Ciner Wyoming shipped substantially all of its soda ash via a Union Pacific rail line. Ciner Wyoming 
relies on the rail line to service its facilities under a contract that expires in 2017. 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, you should not place undue reliance on our reserve data that is included in this report.

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

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

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

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

Risks Related to Our Structure

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

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

Furthermore, if unitholders are dissatisfied with the performance of our general partner, they currently have little practical 
ability to remove our general partner or otherwise change its management. Our general partner may not be removed except upon 
the vote of the holders of at least 66 2/3% of our outstanding units (including units held by our general partner and its affiliates). 
Because  the  owners  of  our  general  partner,  along  with  directors  and  executive  officers  and  their  affiliates,  own  a  significant 
percentage of our outstanding common units, the removal of our general partner would be difficult without the consent of both 
our general partner and its affiliates.

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

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

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

reduction of a takeover premium in the trading price.

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

The preferred units are a new class of partnership interests that 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.

30

We may issue additional common units or preferred units without 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 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 unitholder approval (subject to applicable 
NYSE rules). The issuance of additional common units or other equity securities of equal or senior rank will have the following 
effects:

• 

• 

• 

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

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

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

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

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

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

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

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

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

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

These conflicts may include the following:

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

general partner;

• 

• 

• 

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

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

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

31

• 

• 

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

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

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

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

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

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

Tax Risks to Common 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 you would be substantially reduced.

The anticipated after-tax economic benefit of an investment in our common units depends largely on our being treated as a 
partnership for U.S. federal income tax purposes. Despite the fact that we are organized as a limited partnership under Delaware 
law, we would be treated as a corporation for U.S. federal income tax purposes unless we satisfy a "qualifying income" requirement. 
Based on our current operations, we believe we satisfy the qualifying income requirement. However, we have not requested, and 
do not plan to request, a ruling from the IRS on this or any other matter affecting us. Failing to meet the qualifying income 
requirement or a 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 you would generally 
be taxed again as corporate distributions, and no income, gains, losses, deductions or credits would flow through to you. Because 
tax would be imposed upon us as a corporation, our cash available for distribution to you 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 common 
unitholders, likely causing a substantial reduction in the value of our common 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 you.

32

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

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

However, any interpretation of or modification to the U.S. federal income tax laws may be applied retroactively and could 
make it more difficult or impossible for us to meet the exception for certain publicly traded partnerships to be treated as partnerships 
for U.S. federal income tax purposes. We are unable to predict whether any of these changes or other proposals will ultimately be 
enacted. Any similar or future legislative changes could negatively impact the value of an investment in our common 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, (iii) repealing the percentage depletion 
allowance with respect to coal properties, and (iv) excluding from the definition of domestic production gross receipts all gross 
receipts derived from the sale, exchange, or other disposition of coal, other hard mineral fossil fuels, or primary products thereof. 
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 common units.

You are required to pay taxes on your share of our income even if you do not receive any cash distributions from us. Your share 
of our portfolio income may be taxable to you even though you 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, you are required to pay any federal income taxes and, in some cases, state and local income taxes on your 
share of our taxable income even if you receive no cash distributions from us. You may not receive cash distributions from us 
equal to your share of our taxable income or even equal to the actual tax due from you with respect to that income.

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

33

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 unitholders, and income tax 
liabilities arising therefrom may exceed any distributions made with respect to your units.

In response to current market conditions, we may engage in transactions to reduce our leverage and manage our liquidity that 
would result in income and gain to our unitholders without a corresponding cash distribution. For example, we may sell assets and 
use the proceeds to repay existing debt, in which case, you 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. Unitholders may be allocated income and 
gain from these transactions, and income tax liabilities arising therefrom may exceed any distributions we make to you. 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. 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. 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 common units may be adversely impacted and 
the cost of any IRS contest will reduce our cash available for distribution to you. 

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 common units and the price 
at which they trade. In addition, our costs of any contest by the IRS will be borne indirectly by our unitholders and our general 
partner because the costs will reduce our cash available for distribution.

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

  Pursuant to the Bipartisan Budget Act of 2015, for tax years beginning after December 31, 2017, if the IRS makes audit 
adjustments to our income tax returns, it (and some states) may assess and collect any taxes (including any applicable penalties 
and interest) resulting from such audit adjustment directly from us. To the extent possible under the new rules, our general partner 
may elect to either pay the taxes (including any applicable penalties and interest) directly to the IRS or, if we are eligible, issue a 
revised Schedule K-1 to each unitholder with respect to an audited and adjusted return. Although our general partner may elect to 
have our unitholders take such audit adjustment into account in accordance with their interests in us during the tax year under 
audit, there can be no assurance that such election will be practical, permissible or effective in all circumstances. As a result, our 
current unitholders may bear some or all of the tax liability resulting from such audit adjustment, even if such unitholders did not 
own units in us during the tax year under audit. If, as a result of any such audit adjustment, we are required to make payments of 
taxes, penalties and interest, our cash available for distribution to our unitholders might be substantially reduced. These rules are 
not applicable for tax years beginning on or prior to December 31, 2017.

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

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

34

Tax-exempt entities and non-U.S. persons face unique tax issues from owning our common units that may result in adverse 
tax consequences to them.

Investments in common units by tax-exempt entities, such as employee benefit plans and individual retirement accounts 
(known  as  IRAs),  and  non-U.S.  persons  raise  issues  unique  to  them.  For  example,  virtually  all  of  our  income  allocated  to 
organizations that are exempt from federal income tax, including IRAs and other retirement plans, will be unrelated business 
taxable income and will be taxable to them. Allocations and/or distributions to non-U.S. persons will be reduced by withholding 
taxes imposed at the highest applicable effective tax rate applicable to non-U.S. persons, and non-U.S. persons will be required 
to file U.S. federal income tax returns and pay tax on their share of our taxable income. If you are a tax-exempt entity or a non-
U.S. person, you should consult your tax advisor before investing in our common 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 you. It also could affect the timing of these tax benefits 
or the amount of gain from your sale of common units and could have a negative impact on the value of our common units or 
result in audit adjustments to your tax returns.

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

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

A unitholder whose common units are the subject of a securities loan (e.g., a loan to a "short seller" to cover a short sale of 
common units) may be considered as having disposed of those common units. If so, he would no longer be treated for tax 
purposes as a partner with respect to those common 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 common units are the subject of a securities loan may be considered as having disposed of the loaned common 
units. In that case, the unitholder may no longer be treated for tax purposes as a partner with respect to those common 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 common units may not be reportable by the unitholder and 
any cash distributions received by the unitholder as to those common units could be fully taxable as ordinary income. Unitholders 
desiring to assure their status as partners and avoid the risk of gain recognition from a loan of their common units are urged to 
modify any applicable brokerage account agreements to prohibit their brokers from borrowing their common units.

The sale or exchange of 50% or more of our capital and profits interests during any twelve-month period will result in the 
termination of us as a partnership for federal income tax purposes.

We will be considered to have terminated as a partnership for federal income tax purposes if there is a sale or exchange of 
50% or more of the total interests in our capital and profits within a twelve-month period. For purposes of determining whether 
the 50% threshold has been met, multiple sales of the same interest will be counted only once. The partnership technically terminated 
on August 31, 2016, as a result of the sale or exchange of 50% or more of our capital and profits interest during the prior twelve 

35

month period. Any technical termination, such as the one occurring in 2016, would, among other things, result in the closing of 
our taxable year for all unitholders, which would result in our filing two tax returns for one calendar year and could result in a 
significant deferral of depreciation deductions allowable in computing taxable income for the applicable year. In the case of a 
unitholder reporting on a taxable year other than the calendar year, the closing of our taxable year may also result in more than 
twelve months of our taxable income or loss being includable in taxable income for the unitholder’s taxable year that includes our 
termination. Our termination currently would not affect our classification as a partnership for federal income tax purposes, but it 
would result in our being treated as a new partnership for U.S. federal income tax purposes following the termination. If we were 
treated as a new partnership, we would be required to make new tax elections and could be subject to penalties if we were unable 
to determine that a termination occurred. The IRS has announced a relief procedure whereby if a publicly traded partnership that 
has technically terminated requests and the IRS grants special relief, among other things, the partnership may be permitted to 
provide only a single Schedule K-1 to unitholders for the two short tax periods included in the year in which the termination occurs.

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

In addition to federal income taxes, you 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 you do not live in any of those jurisdictions. You 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, you 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 your responsibility to file all U.S. federal, state and local tax returns.

ITEM 1B.  UNRESOLVED STAFF COMMENTS

None.

ITEM 3.  LEGAL PROCEEDINGS

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

In November 2015, we filed a lawsuit against Foresight Energy’s subsidiary, Hillsboro Energy LLC ("Hillsboro"), in the 
Circuit Court of the Fourth Judicial Circuit in Montgomery County, Illinois. The lawsuit alleges, among other items, breach of 
contract by Hillsboro resulting from a wrongful declaration of force majeure at Hillsboro’s Deer Run mine in July 2015. In late 
March 2015, elevated carbon monoxide readings were detected at the Deer Run mine, and coal production at the mine was idled. 
In July 2015, we received the notice declaring a force majeure event at the mine as a result of the elevated carbon monoxide levels. 
We believe the force majeure claim by Hillsboro has no merit and we are vigorously pursuing recovery against them. However, 
the effect of a valid force majeure declaration would relieve Foresight Energy of its obligation to pay us minimum deficiency 
payments of $7.5 million per quarter, or $30.0 million per year. Foresight Energy's failure to make the deficiency payment with 
respect to the second, third and fourth quarters of 2015 and each quarter of 2016 resulted in a cumulative $46.0 million negative 
cash impact to us. Such amount will increase for each quarter during which mining operations continue to be idled. We do not 
currently have an estimate as to when the mine will resume coal production. If the mine remains idled for an extended period or 
if the mine is permanently closed, our financial condition could be adversely affected.

In April 2016, we filed a lawsuit against Macoupin Energy, LLC ("Macoupin"), a subsidiary of Foresight Energy, in Macoupin 
County, Illinois. The lawsuit alleges that Macoupin has failed to comply with the terms of its coal mining, rail loadout and rail 
loop  leases  by  incorrectly  recouping  previously  paid  minimum  royalties.  Foresight  Energy’s  failure  to  properly  calculate  its 
recoupable balance and failure to make payments in accordance with these lease agreements has resulted in a cumulative $6.2 
million negative cash impact to us. While the Partnership plans to pursue its claim, a valuation allowance for the receivable amount 
has been recorded.

NRP Common Units and Cash Distributions

Our  common  units  are  listed  and  traded  on  the  NYSE  under  the  symbol  "NRP". As  of  February  1,  2017,  there  were 
approximately 26,500 beneficial and registered holders of our common units. The computation of the approximate number of 
unitholders is based upon a broker survey.

The following table sets forth the high and low sales prices per common unit, as reported on the NYSE Composite Transaction 
Tape from January 1, 2015 to December 31, 2016, and the quarterly cash distribution declared and paid with respect to each quarter 
per common unit. The information presented in the tables below has been adjusted to give retroactive effect to the one-for-ten 
reverse unit split that was effective on February 17, 2016.

Non-GAAP Financial Measures

Distributable Cash Flow

Our Distributable Cash Flow ("DCF") represents net cash provided by operating activities of continuing operations, plus 
returns of unconsolidated equity investments, proceeds from sales of assets, including those included in discontinued operations, 
and returns of long-term contract receivables—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. DCF is a 
supplemental liquidity measure used by our management and by external users of our financial statements, such as investors, 
commercial banks, research analysts and others to assess the Partnership's ability to make cash distributions to our unitholders and 
our general partner and repay debt. The following table (in thousands) reconciles net cash provided by operating activities of 
continuing operations (the most comparable GAAP financial measure) to Distributable Cash Flow for the years ended December 
31, 2016, 2015, 2014, 2013 and 2012:

(1)  Maintenance capital expenditures primarily consist of costs to maintain the long-term productive capacity of VantaCore.

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, gain on reserve swaps and income to non-controlling interest; plus distributions 
from  equity  earnings  in  unconsolidated  investment,  interest  expense,  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.   

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.

and Supplementary Data" included elsewhere in this Annual Report on Form 10-K for a description of Opco’s debt agreements.

Net Income from Continuing Operations Excluding Impairments

Net income from continuing operations excluding impairments is a non-GAAP financial measure that we define as net income 
(loss) from continuing operations plus asset impairments. Net income from continuing operations excluding impairments, as used 
and defined by us, may not be comparable to similarly titled measures employed by other companies and is not a measure of 
performance calculated in accordance with GAAP. Net income excluding impairments should not be considered in isolation or as 
a substitute for operating income (loss), net income (loss), cash flows provided by operating, investing and financial activities, or 
other income or cash flow statement data prepared in accordance with GAAP. Our management team believes net income excluding 
impairments  is  useful  in  evaluating  our  financial  performance  because  asset  impairments  are  irregular  non-cash  charges  and 
excluding  these  from  net  income  allows  us  to  better  compare  results  period-over-period.The  following  table  (in  thousands) 
reconciles net income (loss) from continuing operations (the most comparable GAAP financial measure) to net income excluding 
impairment for the years ended December 31, 2016, 2015, 2014, 2013 and 2012:

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, construction aggregates 
and other natural resources. Our common units trade on the New York Stock Exchange under the symbol "NRP".

Our business is organized into three operating segments:

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

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

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

2017 Recapitalization Transactions

We have been pursuing or considering a number of actions in order to mitigate the effects of adverse market developments 
and scheduled debt principal payments since April 2015 when we announced our long-term strategic plan to strengthen our balance 
sheet and enhance our liquidity. On March 2, 2017, we completed the following transactions that achieved these objectives and 
will ultimately reposition the partnership for long-term growth:  

• 

• 

• 

the issuance of $250 million of a new class of 12.0% preferred units representing limited partner interests in NRP, 
together with warrants to purchase common 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"); 

the exchange of $241 million of our 9.125% Senior Notes due 2018 (the "2018 Notes") for $241 million of a new 
series of 10.500% Senior Notes due 2022 (the "2022 Notes"), and the sale of $105 million of additional 2022 Notes 
in exchange for cash proceeds; and

the  extension  of  Opco’s  revolving  credit  facility  (the  "Opco  Credit  Facility")  to April  2020,  with  commitments 
thereunder reduced to $180 million.  

We used a portion of the proceeds from these transactions to repay Opco’s revolving credit facility in full and pay all fees 
and expenses associated with the transactions described above. We will also use a portion of the proceeds to redeem the remaining 
2018 Notes.  On March 3, 2017, we delivered a notice of partial redemption for $90.0 million of our outstanding 2018 Notes at a 
43

redemption price of 104.563%, plus accrued and unpaid interest to the redemption date. This partial redemption of the 2018 Notes 
is expected to occur on April 3, 2017.  We will redeem all of the remaining 2018 Notes within 60 days after October 1, 2017 at 
the then-applicable price and pay all accrued and unpaid interest thereon.

For more information on these transactions, including the terms of the preferred units, warrants and 2022 Notes, see "—

Liquidity and Capital Resources—2017 Recapitalization Transactions."

2016 Asset Sales

Prior to completion of these recapitalization transactions, we had been pursuing or considering a number of actions, including 
dispositions of assets, in order to mitigate the effects of adverse market developments and scheduled debt principal payments.  As 
part of this plan, we sold assets during the year ended December 31, 2016, for total gross proceeds of $181.0 million that consisted 
of the following:

•  Oil and gas working interest in the Williston Basin for $116.1 million gross sales proceeds that marked our exit from 

the non-operated oil and gas working interest business. 

•  Oil and gas royalty and overriding royalty interests in several producing properties located in the Appalachian Basin 

for $36.4 million gross sales proceeds. 

•  Aggregates reserves and related royalty rights at three aggregates operations located in Texas, Georgia and Tennessee 

for $10.0 million gross sales proceeds. 

•  Mineral reserves in multiple sale transactions for cumulative $17.3 million of gross sales proceeds. These amounts 
primarily relate to eminent domain transactions with governmental agencies and the sale of additional oil and gas 
royalty interests. Additional asset sales during the year included sales of land and plant and equipment for $1.2 million 
of gross proceeds.

Current Liquidity

As of December 31, 2016, we had a total of $40.4 million of cash and cash equivalents. During the year ended December 31, 
2016, we reduced our debt by approximately $248.1 million by repaying $85.0 million of the NRP Oil and Gas reserve based 
lending facility in full (the "RBL Facility"), $82.9 million of the Opco Private Placement Notes (as defined below), $80.0 million
of the Opco Credit Facility and $0.2 million of Opco's utility local improvement obligation. 

In March 2017, we increased our liquidity through the completion of the recapitalization transactions described above, 
including by repaying borrowings outstanding under the Opco Credit Facility in full.  In addition to enhancing our liquidity, these 
recapitalization transactions reduced our 2018 debt maturities by $575 million through the extension of debt principal payments 
from 2018 to 2020 and 2022. Even with these meaningful improvements to our liquidity and balance sheet, we continue to have 
substantial debt outstanding and intend to continue to use cash from operations to deleverage our balance sheet over time.  While 
we have a diversified portfolio of assets, we face challenges in coal and other commodity markets.  Our going concern analysis 
included an analysis of these relevant conditions and events and our ability to meet our obligations and remain in compliance with 
our debt covenants within one year after the issuance date of these financial statements. We expect that we will meet all of our 
obligations, including scheduled principal and interest payments on our debt and required distributions on the preferred units, 
comply with all covenants contained in our debt agreements and that we will continue as a going concern.

In the fourth quarter of 2016, we began to realize the benefits of the dramatic increase in metallurgical coal prices as well 
as the improvement in the thermal coal markets. A number of our lessees were able to take advantage of the improved markets 
and lock in tonnage commitments for 2017 at substantially higher prices than they realized in 2016. While spot metallurgical prices 
have recently retreated from the highs reached in the fourth quarter, we believe that that global supply/demand dynamic will support 
long-term metallurgical coal prices well above the lows hit in the first half of 2016. We derived approximately 37% of our coal 
royalty revenues and approximately 35% of the related production from metallurgical coal during the year ended December 31, 
2016. The domestic thermal coal markets have also shown modest improvements, as production cuts over the last year have 
rationalized coal stockpiles. Although a mild winter has tempered demand for thermal coal, natural gas prices remain higher than 
2016, causing thermal coal to be more competitive for electricity generation as compared to recent years.  In addition, we expect 
the actions of the Trump Administration to ease the regulatory burdens on the coal industry, reducing the production costs and 
increasing the competitiveness of our lessees against natural gas.  Despite these improvements, producers of Central Appalachian 
thermal coal continue to face challenges, as many still have large debt burdens and their production costs remain high relative to 
sales prices. We have successfully navigated the bankruptcies of several of our lessees and have had substantially all of our leases 
assumed or assigned and received substantially all past-due amounts in these bankruptcies.  

Production from our Illinois Basin properties decreased by 27% during the year ended December 31, 2016 as compared to 
the year ended December 31, 2015. Substantially all of the decrease is attributable to the idling of Foresight Energy's Deer Run 
mine (which we also refer to as our Hillsboro property) during 2016. In July 2015, we received a notice from Foresight Energy 
declaring a force majeure event at the Deer Run mine after elevated levels of carbon monoxide were detected. We believe Foresight's 
claim of force majeure has no merit and we are vigorously pursuing our claims against them through a lawsuit filed in November 
2015. However, the effect of a valid force majeure declaration would relieve Foresight Energy of its obligation to pay us quarterly 
minimum deficiency payments with respect to the Deer Run mine until mining resumes. Under the lease for the Deer Run mine, 
Foresight Energy is required to make minimum deficiency payments to us of $7.5 million per quarter, or $30.0 million per year. 
Foresight Energy’s failure to make the deficiency payments with respect to the second, third and fourth quarters of 2015 and all 
four quarters of 2016 resulted in a cumulative negative cash impact to us of $46.0 million. Such amount will increase for each 
quarter during which mining operations continue to be idled. Foresight Energy is continuing efforts to reenter the mine, but we 
do not know when, or if, mining activities at the Deer Run mine will recommence.

Income from our trona mining and soda ash refinery investment was lower year-over-year for the year ended December 31, 
2016. This decrease is primarily related to lower international prices compared to the prior year, in addition to higher royalty and 
G&A costs. These decreases were partially offset by an increase in soda ash volumes sold compared to the prior year. Ciner 
Resources LP, our partner that controls and operates Ciner Wyoming, is a publicly traded master limited partnership that depends 
on distributions from Ciner Wyoming in order to make distributions to its public unitholders.

VantaCore’s construction aggregates mining and production business is largely dependent on the strength of the local markets 
that  it  serves.  VantaCore’s  Laurel Aggregates  operation  in  southwestern  Pennsylvania  serves  producers  and  oilfield  service 
companies operating in the Marcellus and Utica Shales and was impacted during the year ended December 31, 2016 by the slowing 
pace of exploration and development of natural gas in those areas due to low natural gas prices. Increased local construction activity 
partially offset these declines during the year ended December 31, 2016, but we expect that Laurel’s business will continue to be 
impacted by decreased natural gas development activities. While VantaCore's production and revenues have declined in 2016 
compared to 2015, its cost management efforts have enabled the business to maintain its profitability.

Discontinued Operations

In July 2016, NRP Oil and Gas closed on the sale of its non-operated oil and gas working interest assets in the Williston 
Basin for $116.1 million in gross sales proceeds. Our exit from our non-operated oil and gas working interest business represented 
a strategic shift to reduce debt and focus on our soda ash, coal royalty and construction aggregates business segments. As a result, 
we have classified the assets and liabilities, operating results and cash flows of our non-operated oil and gas working interest assets 
as discontinued operations in our consolidated financial statements for all periods presented.

Total coal production decreased 16.8 million tons, or 36%, from 47.0 million tons in the year ended December 31, 2015 to 
30.2 million tons in the year ended December 31, 2016. Total coal royalty revenues decreased $42.3 million, or 29%, from $144.0 
million in the year ended December 31, 2015 to $101.8 million in the year ended December 31, 2016. Total coal production and 
coal royalty revenue decreases were driven by downward pressure in the coal markets as described above, with Central Appalachian 
thermal coal producers in particular continuing to face challenges, as their production costs remain high relative to sales prices. 

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

48

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

during the first quarter of 2016:

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

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

Soda Ash

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

VantaCore

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

Operating and Maintenance Expenses (including affiliates)

Operating and maintenance expenses (including affiliates) decreased $21.8 million, or 14%, from $152.3 million in the year 
ended  December 31,  2015  to  $130.5  million  in  the  year  ended  December 31,  2016. This  decrease  is  primarily  related  to  the 
following:

VantaCore

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

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

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

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

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

Asset Impairments 

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

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

VantaCore

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

Income (Loss) from Discontinued Operations 

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

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

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

Total coal production decreased 3.4 million tons, or 7%, from 50.4 million tons in 2014 to 47.0 million tons in 2015. Total 
coal royalty revenues decreased $40.2 million, or 22%, from $184.2 million in 2014 to $144.0 million in 2015. During 2015, 
depressed coal prices negatively affected our coal related revenues. During the year ended December 31, 2015 as compared to 
2014, total coal production and total coal royalty revenues were down in Appalachia, the Illinois Basin and the Gulf Coast, while 
we saw a significant increase in the Northern Powder River Basin. All Appalachian regions saw a decrease in coal royalty revenues 
during the year with coal royalty revenues in Northern Appalachia down 69% despite a 2% increase in production from that area. 
We saw a decrease in the average coal revenue per ton throughout all of our regions, with the exception of the Gulf Coast whose 
average coal revenue per ton remained flat, for the year ended December 31, 2015 when compared to the year ended December 
31, 2014.

55

 
 
 
Other coal royalty and other income increased $17.9 million, or 22%, from $81.9 million in 2014 to $99.8 million in 2015. 
This increase is primarily a result of two lease assignment fee payments received in 2015 totaling $21.0 million, an $8.8 million 
increase in minimums recognized as revenue and a $3.6 million increase in reserve swap gains year-over-year.  These increases 
were partially offset by decreased oil and gas royalty revenue as a result of lower commodity prices year-over-year and decreases 
in hard mineral royalty revenues, property taxes and override revenue in 2015 when compared to 2014.

Soda Ash

Revenues and other income related to our Soda Ash segment increased $8.5 million, or 21%, from $41.4 million in 2014 to 
$49.9 million in 2015.  This increase is primarily related to our allocated percentage of Ciner Wyoming's $15.0 million increase 
in income year-over-year. For the year ended December 31, 2015, we received $46.8 million in cash distributions from Ciner 
Wyoming and for the year ended December 31, 2014, we received $46.6 million in cash distributions. 

VantaCore

Tonnage sold by the VantaCore segment increased 5.1 million tons from 2.3 million tons in 2014 to 7.4 million tons in 2015.  
Revenues and other income related to our VantaCore segment increased $96.9 million, or 231%, from $42.1 million in 2014 to 
$139.0 million in 2015. This increase is due to the fact that VantaCore was acquired in the fourth quarter of 2014.

Operating and Maintenance Expenses (including affiliates)

Operating and maintenance expenses (including affiliates) increased $76.2 million, or 100%, from $76.1 million in 2014 to 

$152.3 million in 2015. This increase is primarily related to the following:

VantaCore

Operating and maintenance expenses in our VantaCore segment increased $78.2 million from $38.7 million in 2014 to $116.9 
million in 2015. This increase is due to the fact that 2014 results only include three months of VantaCore activity as compared to 
twelve months in 2015.

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

DD&A expense decreased $1.0 million from $61.9 million in 2014 to $60.9 million in 2015. This decrease is primarily 

related to the following:

Coal Royalty and Other

DD&A expense for our Coal Royalty and Other segment decreased $13.3 million, or 23%, from $58.6 million in 2014 to 
$45.3 million in 2015. This decrease was primarily the result of the reduction in depletion expense on the assets that were impaired 
during the third and fourth quarters of 2015 and reduced production year-over-year.

VantaCore

DD&A expense for our VantaCore segment increased $12.3 million from $3.3 million in 2014 to $15.6 million in 2015. This 

increase was due to the fact that 2014 results only include three months of activity as compared to a full year in 2015.

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

Corporate and financing G&A expense includes corporate headquarters, financing and centralized treasury and accounting. 
These costs increased $1.8 million, or 17%, from $10.5 million in 2014 to $12.3 million in 2015. This increase was primarily due 
to an increase in salaries, bonus and benefits, consulting, rent and legal fees. This increase was partially offset by a decrease in 
LTIP expense as a result of the decline in unit price year-over-year.

56

Asset Impairment

Asset impairment expense increased $358.3 million from $26.2 million in 2014 to $384.5 million in 2015. We recorded the 

following asset impairments during the years ended December 31, 2015 and 2014 (in thousands):

Asset impairment expense related to our Coal Royalty and Other segment increased $352.1 million from $26.2 million in 
2014 to $378.3 million in 2015. This increase was primarily due to the significant impairment expense taken in the third quarter 
2015. Coal property impairments primarily resulted from idled operations in Appalachia combined with the continued deterioration 
in the coal markets and expectations of further reductions in global and domestic coal demand due to reduced global steel demand, 
low natural gas prices, and continued regulatory pressure on the electric power generation industry. Oil and gas royalty property 
impairments primarily results from declines in future expected realized commodity prices and reduced expected drilling activity 
on our acreage. Aggregate royalty property impairments primarily resulted from greenfield development projects that have not 
performed as projected, leading to recent lease concessions on minimums and royalties combined with the continued regional 
market decline for certain properties. During the fourth quarter of 2015, we recognized an additional $8.2 million impairment 
expense  on  our  coal  properties  as  a  result  of  continued  market  declines  and  $4.7  million  impairment  expense  related  to  coal 
processing and transportation assets as well as obsolete equipment at our Logan office. During the second quarter of 2015 we 
recorded a $2.3 million impairment expense related to a coal preparation plant. 

VantaCore

The $6.2 million impairment expense in 2015 was related to a $5.5 million write off of goodwill as well as a $0.7 million

impairment related to obsolete plant and equipment. 

Interest Expense 

Interest expense increased $10.3 million, or 13%, from $79.4 million in 2014 to $89.7 million in 2015. This increase was 

primarily the result of additional debt incurred to complete acquisitions in the fourth quarter of 2014.

Income (Loss) from Discontinued Operations 

Income from discontinued operations decreased $323.6 million, from income of $12.1 million in 2014 to a loss of $311.5 
million in 2015. The change in income (loss) from discontinued operations primarily related to asset impairments recorded in 2015 
due to the declines in future expected realized commodity prices and reduced expected drilling activity and reduced oil and gas 
prices in 2015 compared to 2014.

Adjusted EBITDA decreased $1.3 million from $263.9 million in 2014 to $262.6 million in 2015. The decrease is mainly 
related to declines in our Coal Royalty and Other segment, partially offset by higher income from our VantaCore business that 
was acquired in October 2014. Adjusted EBITDA is a non-GAAP financial measure. See "Item 6. Selected Financial Data—Non-
GAAP Financial Measures—Adjusted EBITDA" for an explanation of Adjusted EBITDA.

Distributable Cash Flow for 2015 decreased $20.3 million, or 10%, from $196.9 million in 2014 to $176.6 million in 2015. 
This decrease is due primarily to a reduction in cash provided by our coal operations, partially offset by our VantaCore business 
that was acquired in October 2014. Distributable Cash Flow is a non-GAAP financial measure. See "Item 6. Selected Financial 
Data—Non-GAAP Financial Measures—Distributable Cash Flow" for an explanation of Distributable Cash Flow.

Liquidity and Capital Resources

2017 Restructuring Transactions

The following discussion describes the recapitalization transactions completed on March 2, 2017 and the terms of the preferred 

units, warrants to purchase common units and debt securities issued in connection therewith.  

Issuance of Preferred Units and Warrants

We issued $250 million of Class A Convertible Preferred Units representing limited partner interests in NRP (the "Preferred 
Units") to Blackstone and GoldenTree (together the "Preferred Purchasers") pursuant to a Preferred Unit and Warrant Purchase 
Agreement.  We 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 dividends 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").  We 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, we may, at our option, elect to settle the Warrants in common 
units or cash, each on a net basis.  

The Preferred Units have a perpetual term, unless converted or redeemed as described below. The Preferred Units (including 
any PIK Units) are convertible into common units at the election of the holders (1) after the fifth anniversary and prior to the eighth 
anniversary of the issue date at a 7.5% discount to the volume weighted average trading price of our common units (the "VWAP") 
for the 30 trading days immediately prior to the notice of conversion if the 30-day VWAP immediately prior to such notice is 
greater than $51.00 (subject to a maximum of 33% of the Preferred Units per year) and (2) after the eighth anniversary of the issue 
date at a 10% discount to the VWAP for the 30 trading days immediately prior to the notice of conversion.  Instead of issuing 
common units pursuant to clause (1) of the preceding sentence, we have the option to redeem the Preferred Units proposed to be 
converted for cash at a price equal to the Per Unit Purchase Price, plus the value of any accrued and unpaid distributions.  To the 
extent the holders of the Preferred Units have not elected to convert their Preferred Units by the twelfth anniversary of the issue 
date, we have the right to force conversion of the Preferred Units into common units at a 10% discount to the VWAP for the 30 
trading days immediately prior to the notice of conversion.  In addition, we have the ability to redeem at any time (subject to 
compliance with our debt agreements) all or any portion of the Preferred Units (including PIK Units) for cash at the agreed upon 
per unit amount, which is calculated as the Per Unit Purchase Price multiplied by (i) prior to the third anniversary of the closing 
date, 1.50, (ii) on or after the third anniversary of the closing date and prior to the fourth anniversary of the closing date, 1.70 and 
(iii) on or after the fourth anniversary of the closing date, 1.85.  

The terms of the Preferred Units contain certain restrictions on our ability to pay distributions on our common units.  To the 
extent that either (i) our consolidated Leverage Ratio (as defined in the Restated Partnership Agreement) is greater than 3.25x, or 
(ii) the ratio of our Distributable Cash Flow 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), we 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, we may not make distributions on our common units until we have 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, including:

• 

the incurrence of new indebtedness, subject to certain exceptions; 

•  material changes to NRP’s business; 

• 

• 

• 

acquisitions and divestitures in excess of certain dollar thresholds;

amendments to material contracts resulting in a cash impact to NRP in excess of certain dollar thresholds;

settlement of any litigation or regulatory matter resulting in cash payments by NRP in excess of certain thresholds; 
and

61

• 

amendments to related party contracts outside of the ordinary course of business.  

GoldenTree also has more limited approval rights that will expand once Blackstone's ownership goes below the Minimum 
Preferred Unit Threshold (as defined below). The Preferred Purchaser Approval Rights are not transferrable without our consent.  
In addition, the Preferred Purchaser 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").  To the extent any Preferred Units that have converted into common units are still held by 
the applicable Preferred Purchaser (or its affiliates), such common units will be deemed to represent a number of Preferred Units 
based on the weighted average number of common units issued in each conversion and will count towards the Minimum Preferred 
Unit Threshold.  

The foregoing terms of the Preferred Units are reflected in our Fifth Amended and Restated Agreement of Limited Partnership, 
dated as of March 2, 2017, which is filed as Exhibit 3.2 to this Annual Report on Form 10-K and incorporated herein by reference. 
The terms of the Warrants are reflected in the Form of Warrant to Purchase Common Units filed as Exhibit 4.28 to this Annual 
Report on Form 10-K, which is incorporated herein by reference.

At the closing, pursuant to a Board Representation and Observation Rights Agreement, the Preferred Purchasers received 
certain board appointment and observation rights and appointed one director and one observer to the Board of Directors of GP 
Natural Resource Partners LLC.  For more information on these rights, see "Certain Relationships and Related Transactions, and 
Director Independence—Board Representation and Observation Rights Agreement."  

We also entered into a registration rights agreement (the "Preferred Unit and Warrant Registration Rights Agreement") with 
the Preferred Purchasers, pursuant to which we are 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. If the shelf registration statements are not effective by the 
applicable Registration Deadline, we 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.

Opco Credit Facility Amendment

We entered into the Second Amendment to Opco’s Third Amended and Restated Credit Agreement to extend the term thereof 
until April 2020, and reduced the commitments of the lenders to $180 million (from $210 million) effective at the closing of the 
recapitalization transactions.  Pursuant the Second Amendment, commitments under the Opco Credit Facility will be reduced to 
$150 million at December 31, 2017 and further reduced to $100 million at December 31, 2018 through maturity in April 2020.  
The amendment does not change the pricing grid or financial covenants under the Opco Credit Facility; provided, however, that 
if we increase our quarterly distribution to our 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.  Other terms of the Second Amendment include 
revisions to the mandatory prepayment provisions with respect to net cash proceeds received from certain asset sales, additional 
limitations on the ability of Opco and its subsidiaries to make certain investments.  The Second Amendment is filed as Exhibit 
10.14 to this Annual Report on Form 10-K and is incorporated herein by reference.

Issuance of 2022 Notes; Exchange and Redemption of 2018 Notes 

NRP and NRP Finance issued $346 million aggregate principal amount of 10.500% Senior Notes due 2022 to several holders 
of its 2018 Notes.  Of the $346 million of 2022 Notes issued, $241 million in aggregate principal amount were issued in exchange 
for $241 million in aggregate principal amount of 2018 Notes, and $105 million of the 2022 Notes were issued to the holders in 
exchange for cash.  The 2022 Notes are issued under an Indenture dated as of March 2, 2017 (the "2022 Indenture"), bear interest 
at 10.500% per year, are payable semi-annually on March 15 and September 15, beginning September 15, 2017, and mature on 
March 15, 2022.

62

We and NRP Finance have the option to redeem the 2022 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, we may on any one or more occasions 
redeem up to 35% of the aggregate principal amount of the 2022 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 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 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 Notes may require 
us to purchase their 2022 Notes at a purchase price equal to 101% of the principal amount of the 2022 Notes, plus accrued and 
unpaid interest, if any.  The 2022 Notes purchased for cash were issued at a price of 98.75% (original issue discount of 1.25%), 
and each holder exchanging 2018 Notes received a fee of 5.813% of the aggregate principal amount of all 2018 Notes tendered 
for exchange by such holder, as well as all accrued and unpaid interest thereon.

The 2022 Indenture contains restrictive covenants that are substantially similar to those contained in the Indenture governing 
the 2018 Notes, except that the debt incurrence and restricted payments covenants contain additional restrictions.  Under the debt 
incurrence covenant, our 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 our 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 we have made the election described in clause (i) above). Under the restricted 
payments covenant, we will not be able to increase the quarterly distribution on our common units or elect to pay more than 50% 
of the distributions required to be made on the Preferred Units in the form of cash, unless, in each case, our consolidated leverage 
ratio is less than 4.00x.  The 2022 Indenture also contains restrictions on our ability to redeem the Preferred Units in cash.

The 2022 Notes are the senior unsecured obligations of NRP and NRP Finance.  The 2022 Notes rank equal in right of 
payment to all existing and future senior unsecured debt of NRP and NRP Finance, including the remaining outstanding 2018 
Notes, and senior in right of payment to any of our subordinated debt.  The 2022 Notes are effectively subordinated in right of 
payment to all future secured debt of NRP and NRP Finance to the extent of the value of the collateral securing such indebtedness 
and are structurally subordinated in right of payment to all existing and future debt and other liabilities of our subsidiaries, including 
the Opco Credit Facility and each series of Opco’s existing senior notes.  None of our subsidiaries guarantee the 2022 Notes.

The terms of the 2022 Notes are more fully described in the 2022 Indenture, which is filed as Exhibit 4.24 to this Annual 

Report on Form 10-K and incorporated herein by reference.

We entered into a registration rights agreement (the "Notes Registration Rights Agreement") with the holders of the 2022 
Notes, pursuant to which we and NRP Finance agreed to file a registration statement with the Securities and Exchange Commission 
for the benefit of the holders of the 2022 Notes so that such holders can exchange the 2022 Notes for exchange securities that have 
substantially identical terms as the 2022 Notes. We and NRP Finance agreed to use commercially reasonable efforts to cause the 
exchange to be completed within 180 days after the closing and will be required to pay additional interest, as specified in the Notes 
Registration Rights Agreement, if we fail to comply with our obligations to register the 2022 Notes within the specified time 
periods.

We expect to redeem $90 million in aggregate principal amount of the 2018 Notes at a redemption price of 104.563%, and 
pay all accrued and unpaid interest thereon, in April 2017.  In addition, we are required to redeem any and all remaining outstanding 
2018 Notes (and pay all accrued and unpaid interest thereon) within 60 days after October 1, 2017.

(1)  Assumes no additional borrowings under the Opco Credit Facility following closing.

Current Liquidity

Generally, we satisfy our working capital requirements with cash generated from operations. Our current liabilities exceeded 
our current assets by approximately $83.8 million as of December 31, 2016, primarily due to $80.6 million in total principal 
payments due in 2017 on the Opco Senior Notes and Opco utility local improvement obligation and $60.0 million of payments 
due in 2017 on the Opco Credit Facility. Excluding these principal payments, our current assets exceeded our current liabilities 
by approximately $56.8 million as of December 31, 2016. In March 2017, we increased our liquidity through the completion of 
the recapitalization transactions described above.  In addition to enhancing our liquidity, these recapitalization transactions reduced 
our 2018 debt maturities by $575 million through the extension of debt principal payments from 2018 to 2020 and 2022.

Capital Expenditures

A portion of the capital expenditures associated with our VantaCore segment are maintenance capital expenditures, which 
are capital expenditures made to maintain the long-term production capacity of those businesses. Expansion capital expenditures 
are  made  to  increase  productive  capacity.  We  deduct  maintenance  capital  expenditures  when  calculating  DCF.  VantaCore’s 
maintenance  and  expansion  capital  expenditures  for  the  year  ended  December  31,  2016 were  $4.4  million  and  $1.0  million, 
respectively.

Cash Flows 

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

64

 
Cash flow provided by operating activities decreased $7.4 million, from $210.8 million in the year ended December 31, 
2014 to $203.4 million in the year ended December 31, 2015. Operating cash flow from continuing operations decreased $33.7 
million in our Coal Royalty and Other segment year-over-year primarily as a result of the reduction in coal royalty revenue and 
reduction of coal royalty minimum cash payments received on certain leases. Corporate and Financing used an additional $11.4 
million in operating activities of continuing operations primarily due to the increase in cash paid for interest year-over-year. These 
decreases were partially offset by a $20.9 million increase in cash provided by operating activities of continuing operations in our 
VantaCore segment primarily due to a full year of operations due to the fourth quarter of 2014 acquisition. Cash flow provided by 
operating activities of discontinued operations increased $16.3 million, from $18.6 million in the year ended December 31, 2014 
to $34.9 million in the year ended December 31, 2015 primarily as a result of a full year of revenue on our fourth quarter 2014 
Williston Basin non-operated working interest asset acquisition. 

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

Cash flow used by investing activities decreased $490.2 million, from $520.5 million in the year ended December 31, 2014 
to $30.3 million in the year ended December 31, 2015 primarily due to the 2014 VantaCore acquisition and various 2015 asset 
sales including an aggregate preparation plant, cell phone tower lease contracts and condemnation payments within our Coal 
Royalty and Other segment, partially offset by plant and equipment acquisitions within our VantaCore segment. Cash flow used 
by investing activities of discontinued operations decreased $313.7 million primarily due to our 2014 investing activities consisting 
of our Sanish Field acquisition as well as additional capital expenditures related to the participation in new wells, partially offset 
by 2015 well participation costs.

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

Cash flow used in financing activities increased $438.8 million, from $267.3 million provided in the year ended December 
31, 2014 to $171.5 million used in the year ended December 31, 2015 primarily due to $518.4 million in loan proceeds and $127.2 
million in general partner contributions received during the year ended December 31, 2014. This change was partially offset by 
higher distributions to partners and loan repayments made during 2014. Cash flow provided by financing activities of discontinued 
operations decreased $321.5 million, from $333.3 million in the year ended December 31, 2014 to $11.8 million provided in the 
year ended December 31, 2015, primarily as a result of contributions from continuing operations to fund investing activities of 
the discontinued operation in 2014.

Summary of Critical Accounting Estimates

Preparation of the accompanying financial statements in conformity with accounting principles generally accepted in the 
United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities in 
the  accompanying  Consolidated  Balance  Sheets  and  the  reported  amounts  of  revenues  and  expenses  in  the  accompanying 
Consolidated Statements of Comprehensive Income during the reporting period. See "Note 2. Summary of Significant Accounting 
Policies" to the audited consolidated financial statements under Item 8 of this Form 10-K for discussion of our significant accounting 
policies. The following critical accounting policies are affected by estimates and assumptions used in the preparation of Consolidated 
Financial Statements.

Revenues

Coal Royalty and Other Revenues.     Coal royalty and other revenues are recognized on the basis of tons of mineral sold by 
our lessees and the corresponding revenue from those sales. Generally, the lessees make payments to us based on the greater of a 
percentage of the gross sales price or a fixed price per ton of mineral they sell. Processing fees are recognized on the basis of tons 
of material processed through the facilities by our lessees and the corresponding revenue from those sales. Generally, the lessees 
of the processing facilities make payments to us based on the greater of a percentage of the gross sales price or a fixed price per 
ton of material that is processed and sold from the facilities. The processing leases are structured in a manner so that the lessees 
are responsible for operating and maintenance expenses associated with the facilities. Other revenues include transportation and 
processing fees. Transportation fees are recognized on the basis of tons of material transported over the beltlines. Under the terms 
of the transportation contracts, we receive a fixed price per ton for all material transported on the beltlines.

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

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

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

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

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

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

VantaCore Revenues.     Revenues from the sale of aggregates, gravel, sand and asphalt are recorded based upon the transfer 
of product at delivery to customers, which generally occurs at the quarries or asphalt plants. Revenues from long-term construction 
contracts are recognized on the percentage-of-completion method, measured by the percentage of total costs incurred to date to 
the estimated total costs for each contract. That method is used since we consider total cost to be the best available measure of 
progress on the contracts. Provisions for estimated losses on uncompleted contracts are made in the period in which such losses 

67

are determined. Changes in job performance, job conditions and estimated profitability, including those arising from final contract 
settlements, which result in revisions to job costs and profits are recognized in the period in which the revisions are determined. 
Contract costs include all direct job costs and those indirect costs related to contract performance, such as indirect labor, supplies, 
insurance, equipment maintenance and depreciation. General and administrative costs are charged to expense as incurred.

Mineral Rights

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

Asset Impairment

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

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

Recent Accounting Standards

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

ITEM 7A.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

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

Commodity Price Risk

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

68

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

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

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

Interest Rate Risk

Our exposure to changes in interest rates results from our borrowings under the Opco Credit Facility, which is subject to 
variable interest rates based upon LIBOR. At December 31, 2016, we had $210.0 million outstanding in variable interest rate debt. 
If interest rates were to increase by 1%, annual interest expense would increase approximately $2.1 million, assuming the same 
principal amount remained outstanding during the year.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Partners of Natural Resource Partners L.P.

We have audited the accompanying consolidated balance sheets of Natural Resource Partners L.P. as of December 31, 2016 and 
2015, and the related consolidated statements of comprehensive income (loss), partners’ capital and cash flows for each of the 
three  years  in  the  period  ended  December  31,  2016.  These  financial  statements  are  the  responsibility  of  the  Partnership's 
management. Our responsibility is to express an opinion on these financial statements based on our audits. We did not audit the 
financial statements of Ciner Wyoming LLC (Ciner Wyoming), a Limited Liability Company in which Natural Resource Partners 
L.P. owns a 49% interest.  In the consolidated financial statements Natural Resource Partners L.P.’s investment in Ciner Wyoming 
is stated at $256 million and $262 million as of December 31, 2016 and 2015 respectively, and Natural Resource Partners L.P.’s 
equity in the net income of Ciner Wyoming is stated at $40 million, $50 million, and $41 million for each of the three years in the 
period ended December 31, 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 LLC, is based on the report of the other auditors.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). 
Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements 
are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures 
in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by 
management, as well as evaluating the overall financial statement presentation. We believe that our audits and the report of the 
other auditors provide a reasonable basis for our opinion.

In our opinion, based on our audits and the report of other auditors, the financial statements referred to above present fairly, in all 
material respects, the consolidated financial position of Natural Resource Partners L.P. at December 31, 2016 and 2015, and the 
consolidated results of its operations and its cash flows for each of the three years in the period ended December 31, 2016, in 
conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), 
Natural Resource Partners L.P.'s internal control over financial reporting as of December 31, 2016, 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 6, 2017 expressed an unqualified opinion thereon.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 

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

We have audited the accompanying balance sheets of Ciner Wyoming LLC (the "Company") as of December 31, 2016 and 
2015 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, 2016. These financial statements are the responsibility of the Company’s management. 
Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United 
States) 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. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial 
reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures 
that are appropriate in the circumstances, 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. An audit also includes examining, on a test 
basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and 
significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our 
audits provide a reasonable basis for our opinion.

In our opinion, such financial statements present fairly, in all material respects, the financial position of the Company as of 
December 31, 2016 and 2015, and the results of its operations and its cash flows for each of the three years in the period ended 
December 31, 2016, in conformity with accounting principles generally accepted in the United States of America.

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

1.    Organization and Nature of Operations

Natural Resource Partners L.P. (the "Partnership"), a Delaware limited partnership, was formed in April 2002. The general 
partner of the Partnership is NRP (GP) LP ("NRP GP"), a Delaware limited partnership, whose general partner is GP Natural 
Resource Partners LLC, a Delaware limited liability company. The Partnership engages principally in the business of owning, 
operating, managing and leasing a diversified portfolio of mineral properties in the United States, including interests in coal, trona 
and soda ash, construction aggregates and other natural resources and is organized into three operating segments further described 
in Note 4. 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, a limited liability company 
wholly owned by Corbin J. Robertson, Jr., owns all of the membership interest in GP Natural Resource Partners LLC. Mr. Robertson 
is entitled to nominate all ten of the directors to the board of directors of GP Natural Resource Partners LLC. Mr. Robertson has 
delegated the right to nominate two of the directors, one of whom must be independent, to Adena Minerals, LLC, an affiliate of 
Christopher Cline.

2.    Summary of Significant Accounting Policies

Basis of Presentation

The accompanying Consolidated Financial Statements of the Partnership have been prepared in accordance with generally 
accepted accounting principles in the United States of America ("GAAP"). The consolidated financial statements include the 
accounts of Natural Resource Partners L.P. and its wholly owned subsidiaries, as well as BRP LLC ("BRP"), a joint venture with 
International Paper Company controlled by the Partnership. The Partnership has an equity investment through which it is able to 
exercise significant influence over but does not control the investee and is not the primary beneficiary of the investee’s activities 
which is accounted for using the equity method. Intercompany transactions and balances have been eliminated.

Management’s Going Concern Analysis

While NRP has a diversified portfolio of assets and a history and continued forecast of profitable operations with positive 
operating cash flows, its operating results and credit metrics have been impacted by challenges in coal and other commodity 
markets. The following going concern analysis includes discussion of the relevant conditions and events and an evaluation of 
NRP's ability to meet its obligations and remain in compliance with its debt covenants within one year after the issuance date of 
these financial statements.

In order to mitigate the effect of these adverse market developments on the Partnership's ability to remain in compliance 
with the covenants under its debt agreements and meet scheduled debt principal payments, the Partnership pursued or considered 
a number of actions. On a cumulative basis since January 1, 2015, the Partnership reduced debt by $339.1 million and completed 
asset sales for $199 million in gross sales proceeds.  In addition, the Partnership completed the following series of recapitalization 
transactions on March 2, 2017 (see Note 19. Subsequent Events for further detail):  

• 

• 

• 

the issuance of $250 million of a new class of 12.0% preferred units representing limited partner interests in NRP, 
together with warrants to purchase common 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"); 

the exchange of $241 million of our 9.125% Senior Notes due 2018 (the "2018 Notes") for $241 million of a new 
series of 10.500% Senior Notes due 2022 (the "2022 Notes"), and the sale of $105 million of additional 2022 Notes 
in exchange for cash proceeds; and

the  extension  of  Opco’s  revolving  credit  facility  (the  "Opco  Credit  Facility")  to April  2020,  with  commitments 
thereunder reduced to $180 million.  

78

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

These recapitalization transactions increased the Partnership's liquidity and reduced the Partnership's 2018 debt maturities 
by $575 million through the extension of debt principal payments from 2018 to 2020 and 2022. While the Partnership continues 
to face challenges in coal and other commodity markets, it expects that it will meet all of its obligations, including scheduled 
principal and interest payments on its debt and required distributions on the convertible preferred units, that it will remain in 
compliance with its debt covenants and that it will continue as a going concern. 

Recasting of Certain Prior Period Information

As described in Note 3. Discontinued Operations, the Partnership has classified the assets and liabilities, operating results 
and cash flows of its non-operated oil and gas working interest assets as discontinued operations in its consolidated financial 
statements for all periods presented.  As described in Note 4. Segment Information, the Partnership has reclassified oil and gas 
royalty activities in prior period amounts to conform to the way it internally manages and monitors segment performance that had 
no impact on the Partnership's consolidated financial position, net income (loss) or cash flows.  

On January 1, 2016, the Partnership adopted a new accounting standard using a retrospective approach that required the 
presentation of the Partnership's debt issuance costs as a direct deduction from the related debt liability, rather than recorded as an 
asset. The adoption resulted in a reclassification that reduced other current assets and short-term debt by $0.2 million and reduced 
other assets and long-term debt (including affiliate) by $13.8 million on the Partnership’s Consolidated Balance Sheet at December 
31, 2015.

Reverse Unit Split

On January 26, 2016, the board of directors of our general partner approved a 1-for-10 reverse split on our common units, 
effective following market close on February 17, 2016. Pursuant to the authorization provided, the Partnership completed the 1-
for-10 reverse unit split and its common units began trading on a reverse unit split-adjusted basis on the New York Stock Exchange 
on February 18, 2016. As a result of the reverse unit split, every 10 outstanding common units were combined into one common 
unit. The reverse unit split reduced the number of common units outstanding from 122.3 million units to approximately 12.2 
million units. All units and per unit data included in the December 31, 2015 consolidated financial statements were retroactively 
restated to reflect the reverse unit split.

Use of Estimates

Preparation of the accompanying financial statements in conformity with accounting principles generally accepted in the 
United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities in 
the  accompanying  Consolidated  Balance  Sheets  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.

Business Combinations

For purchase acquisitions accounted for as business combinations, the Partnership is required to record the assets acquired, 
including identified intangible assets and liabilities assumed at their fair value, which in many instances involves estimates based 
on third party valuations, such as appraisals, or internal valuations based on discounted cash flow analyses or other valuation 
techniques.

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 12. Fair Value Measurements."

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

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

79

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

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

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

Cash and Cash Equivalents

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

cash equivalents.

Accounts Receivable

Accounts receivable from the Partnership’s lessees and customers do not bear interest. Receivables are recorded net of the 
allowance for doubtful accounts in the accompanying Consolidated Balance Sheets. The Partnership evaluates the collectability 
of its accounts receivable based on a combination of factors. The Partnership regularly analyzes its accounts receivable and when 
it becomes aware of a specific lessee’s or customer’s inability to meet its financial obligations to the Partnership, such as in the 
case of bankruptcy filings or deterioration in the lessee’s or customer’s operating results or financial position, the Partnership 
records a specific reserve for bad debt to reduce the related receivable to the amount it reasonably believes is collectible. The 
reserve is recognized as a reduction in the accounts receivable and an increase in operating and maintenance expenses or operating 
and  maintenance  expenses—affiliates. Accounts  are  charged  off  when  collection  efforts  are  complete  and  future  recovery  is 
doubtful. The allowance for doubtful accounts included in the Partnership's net accounts receivable balance (including affiliates) 
was  $4.6  million  and  $5.3  million  at  December 31,  2016  and  December 31,  2015,  respectively. A  significant  amount  of  the 
Partnership's allowance for doubtful accounts relates to allowances for doubtful coal-related receivables.  

Inventory

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

Plant and Equipment

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

Buildings and improvements
Machinery and equipment
Leasehold improvements

Years

20 to 40
5 to 12
Life of Lease

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

80

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

Mineral Rights

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

Intangible Assets

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

Asset Impairment

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

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

Revenue Recognition

Coal Royalty and Other Revenues.     Coal royalty and other revenues are recognized on the basis of tons of mineral sold by 
our lessees and the corresponding revenue from those sales. Generally, the lessees make payments to us based on the greater of a 
percentage of the gross sales price or a fixed price per ton of mineral they sell. Processing fees are recognized on the basis of tons 
of material processed through the facilities by our lessees and the corresponding revenue from those sales. Generally, the lessees 
of the processing facilities make payments to us based on the greater of a percentage of the gross sales price or a fixed price per 
ton of material that is processed and sold from the facilities. The processing leases are structured in a manner so that the lessees 
are responsible for operating and maintenance expenses associated with the facilities. Other revenues include transportation and 
processing fees. Transportation fees are recognized on the basis of tons of material transported over the beltlines. Under the terms 
of the transportation contracts, the Partnership receives a fixed price per ton for all material transported on the beltlines. 

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

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

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

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

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

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

VantaCore Revenues.     Revenues from the sale of aggregates, gravel, sand and asphalt are recorded based upon the transfer 
of product at delivery to customers, which generally occurs at the quarries or asphalt plants. Revenues from long-term construction 
contracts are recognized on the percentage-of-completion method, measured by the percentage of total costs incurred to date to 
the estimated total costs for each contract. That method is used since the Partnership considers total cost to be the best available 
measure of progress on the contracts. Provisions for estimated losses on uncompleted contracts are made in the period in which 
such losses are determined. Changes in job performance, job conditions and estimated profitability, including those arising from 
final contract settlements, which result in revisions to job costs and profits are recognized in the period in which the revisions are 
determined. Contract costs include all direct job costs and those indirect costs related to contract performance, such as indirect 
labor, supplies, insurance, equipment maintenance and depreciation. General and administrative costs are charged to expense as 
incurred.

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 Coal Royalty and Other revenues and in Operating and maintenance expenses, respectively, in the 
Consolidated Statements of Comprehensive Income.

Transportation Revenue and Expense

The Company records transportation revenue and pays transportation costs to a Foresight affiliate to operate equipment on 
behalf of the Company. The revenue and expenses related to these transactions are recorded as Coal Royalty and Other—affiliates 
revenues and Operating and maintenance expenses—affiliates in the Consolidated Statements of Comprehensive Income. Shipping 
and  handling  costs  invoiced  to  aggregate  customers  and  paid  to  third-party  carriers  are  recorded  as VantaCore  revenues  and 
Operating and maintenance expenses in the Consolidated Statements of Comprehensive Income. Shipping and handling revenue 
included in VantaCore revenues was $36.0 million, $42.6 million and $14.0 million for the years ended December 31, 2016, 2015 
and 2014, respectively. Shipping and handling costs included in Operating and maintenance expenses was $35.9 million, $42.1 
million and $13.9 million for the years ended December 31, 2016, 2015, and 2014, respectively.

Unit-Based Compensation

The Partnership has awarded unit-based compensation in the form of phantom units that are more fully described in Note 16. 

Unit-Based Compensation. A summary of our accounting policy for unit-based awards follows.

The Partnership accounts for awards relating to its unit-based Long-Term Incentive Plan using the fair value method, which 
requires the Partnership to estimate the fair value of the grant, and charge or credit the estimated fair value to expense over the 
requisite service period of the grant based on fluctuations in the Partnership’s common unit price. In addition, estimated forfeitures 
are included in the periodic computation of the fair value of the liability and the fair value is recalculated at each reporting date 
over the service or vesting period of the grant. 

Deferred Financing Costs

Deferred financing costs consist of legal and other costs related to the issuance of the Partnership’s long-term debt. These 
costs are amortized over the term of the debt.  Deferred financing costs for existing debt agreements are included as a a direct 
deduction  from  the  related  debt  liability  on  the  Partnership's  Consolidated  Balance  Sheets.  Deferred  financing  costs  that  the 
Partnership has incurred related to its restructuring efforts are included in Other Assets on the Partnership's Consolidated Balance 
Sheets until the related debt agreement has been executed.

Income Taxes

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

Lessee Audits and Inspections

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

Recently Issued Accounting Standards

The Financial Accounting Standards Board ("FASB") issued guidance that requires an entity's management to evaluate, for 
each reporting period, whether there are conditions and events that raise substantial doubt about the entity’s ability to continue as 
a  going  concern  within  one  year  after  the  financial  statements  are  issued. Additional  disclosures  are  required  if  management 
concludes that conditions or events raise substantial doubt about the entity’s ability to continue as a going concern. The Partnership 
adopted this guidance on December 31, 2016. For additional information, see Management’s Going Concern Analysis located in 
this footnote above. 

83

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

The FASB issued authoritative guidance on revenue recognition. The core principle of this guidance is that an entity should 
recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration 
to  which  the  entity  expects  to  be  entitled  in  exchange  for  those  goods  or  services.   The  guidance  will  also  require  enhanced 
disclosures, provide more comprehensive guidance for transactions such as service revenue and contract modifications, and enhance 
guidance for multiple-element arrangements. The Partnership is required to adopt this guidance in the first quarter of 2018 using 
one of two retrospective application methods. The Partnership has performed revenue scoping procedures to identify the contracts 
for all of its revenue streams and utilized the practical expedient of grouping contracts or performance obligations with similar 
characteristics as prescribed by the new standard. The Partnership is currently evaluating these contracts and while the effect of 
adoption  is  unknown,  it  is  not  currently  aware  of  any  material  changes  that  would  result  from  adoption  of  this  new  revenue 
recognition guidance and expects to complete its assessment of how it will be affected in the second quarter of 2016. The Partnership 
anticipates utilizing the full retrospective adoption method for financial statement comparability and electing the practical expedient 
of not restating contracts that begin and are completed within the same annual reporting period.

The FASB issued authoritative guidance which intended to simplify the measurement of inventory. This guidance requires 
an entity to measure inventory at the lower of cost or net realizable value, and defines net realizable value as the estimated selling 
price in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. This guidance 
is effective for annual and interim periods beginning after December 15, 2016. The Partnership does not expect for the adoption 
of this guidance to have a material impact on its consolidated financial statements.

The FASB issued authoritative lease guidance that requires lessees 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. 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 ending after December 31, 2018. The Partnership is 
currently evaluating the impact of the provisions of this guidance on its consolidated financial statements.

The FASB issued authoritative guidance that replaces the incurred loss impairment methodology in the current standard with 
a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable 
information to inform credit loss estimates. The guidance is effective for annual and interim periods ending after December 31, 
2019. The Partnership is currently evaluating the impact of the provisions of this guidance on its consolidated financial statements.

The FASB issued authoritative guidance to clarify how certain cash receipts and cash payments are presented and classified 
in the statement of cash flows in order to reduce current and potential future diversity in practice. The guidance is effective for 
annual and interim periods ending after December 31, 2017. The Partnership is currently evaluating the impact of the provisions 
of this guidance on its consolidated financial statements.

3.    Discontinued Operations

In June 2016, NRP Oil and Gas signed a definitive agreement to sell its non-operated oil and gas working interest assets 
assets for $116.1 million in gross sales proceeds, and the Partnership determined it met the criteria required for held for sale 
classification. In July 2016, NRP Oil and Gas closed this transaction, which had an effective date of April 1, 2016. 

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

4.    Segment Information

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

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

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

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

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

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

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

5.    Acquisitions and Divestitures

Acquisitions

On October 1, 2014, the Partnership completed its acquisition of VantaCore for total consideration of $200.6 million in cash 
and common units. The Partnership funded this acquisition through the borrowing of $169.0 million under its Opco’s revolving 
credit facility and the issuance of 0.2 million common units to certain of the sellers. Revenue and operating income from VanataCore 
included in the Consolidated Statements of Comprehensive Income were $42.1 million and $0.1 million, respectively, for the year 
ended December 31, 2014. 

On November 12, 2014, the Partnership completed its acquisition of non-operated oil and gas working interests in the Sanish 
Field of the Williston Basin from an affiliate of Kaiser-Francis Oil Company for $339.1 million. These non-operated working 
interest assets were sold during 2016 as discussed in Note 3. Discontinued Operations. The Partnership funded this acquisition 
using  the  net  proceeds  from  the  issuance  of  additional  $125  million  principal  amount  of  its  9.125%  Senior  Notes  due  2018, 
borrowing $117.0 million under an NRP Oil and Gas revolving credit facility and proceeds of $100.4 million from a public common 
unit offering. Revenue and operating income from these acquired oil and gas assets included in the Consolidated Statements of 
Comprehensive Income were $12.8 million and $3.7 million, respectively, for the year ended December 31, 2014. 

These acquisitions were accounted for under the acquisition method of accounting for businesses. Accordingly, the Partnership 
conducted assessments of net assets acquired and recognized amounts for identifiable assets acquired and liabilities assumed at 
their estimated fair values on the acquisition dates, while transaction and integration costs associated with the acquisitions were 
expensed as incurred. The results of operations of all acquisitions have been included in the consolidated financial statements since 
the  acquisition  dates.  The  following  unaudited  pro  forma  financial  information  (in  thousands)  presents  a  summary  of  the 
Partnership’s consolidated revenues, net income and net income per common unit for the twelve months ended December 31, 2014

As discussed in Note 2. Summary of Significant Accounting Policies, the Partnership has been and is currently pursuing or 
considering a number of actions, including dispositions of assets, in order to mitigate the effects of adverse market developments 
which could otherwise cause the Partnership to breach financial covenants under its debt agreements, and mitigate the effects of 
scheduled debt principal payments that will strain the Partnership's liquidity. As part of this plan, the Partnership completed the 
sale of the following assets during the year ended December 31, 2016:

1)  Oil  and  gas  working  interest  in  the Williston  Basin  for  $116.1  million  gross  sales  proceeds,  as  discussed  in  Note  3. 

Discontinued Operations.

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

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

4)  In addition to the asset sales described above, during the year ended December 31, 2016, the Partnership sold mineral 
reserves  within  its  Coal  Royalty  and  Other  segment  in  multiple  sale  transactions  for  cumulative  $17.3  million  of  gross  sales 
proceeds and recorded $8.6 million of cumulative gain from these sale transactions that are included in Gain on asset sales, net

on its Consolidated Statement of Comprehensive Income. These amounts primarily relate to eminent domain transactions with 
governmental agencies and the sale of additional oil and gas royalty interests.

Additional asset sales during the year included sales of land and plant and equipment within the Coal Royalty and Other 
segment for $1.2 million of gross proceeds and a $0.3 million of cumulative gain from these transactions that are included in Gain 
on asset sales, net on the Consolidated Statement of Comprehensive Income.

During the year ended December 31, 2015, the Partnership sold mineral reserves in multiple transactions for cumulative 
$3.5 million of gross sales proceeds and recorded a $3.3 million gain on asset sales included in Gain on asset sales, net on its 
Consolidated Statement of Comprehensive Income. The Partnership sold intangible assets for $4.4 million in gross proceeds and 
recorded a gain of $3.1 million included in Gain on asset sales, net in the Consolidated Statement of Comprehensive Income. The 
Partnership also sold plant and equipment $6.7 million of gross proceeds and recorded a gain of $0.6 million included in Gain on 
asset sales, net on the Consolidated Statement of Comprehensive Income. 

During the year ended December 31, 2014, the Partnership sold land and mineral reserves for $1.4 million in gross sales 
proceeds and recorded a cumulative gain of  $1.4 million on these asset sales included in Gain on asset sales, net on its Consolidated 
Statement of Comprehensive Income. 

6.    Equity Investment 

The Partnership accounts for its 49% investment in Ciner Wyoming using the equity method of accounting. Ciner Wyoming 
distributed $46.6 million, $46.8 million and $46.6 million to the Partnership in the year ended December 31, 2016, 2015 and 2014, 
respectively. 

The difference between the amount at which the investment in Ciner Wyoming is carried and the amount of underlying 
equity in Ciner Wyoming's net assets was $150.0 million and $154.8 million as of December 31, 2016 and 2015, respectively.  
This excess basis relates to plant, property and equipment and right to mine assets. The excess basis difference that relates to 
property, plant and equipment is being amortized into income using the straight-line method over a weighted average of 28 years. 
The excess basis difference that relates to right to mine assets is being amortized into income using the units of production method.

Impairment of Mineral Rights 

The  Partnership  has  developed  procedures  to  periodically  evaluate  its  long-lived  assets  for  possible  impairment. These 
procedures are performed throughout the year and consider both quantitative and qualitative information based on historic, current 
and future performance and are designed to identify impairment indicators. If an impairment indicator is identified, additional 
evaluation is performed for that asset that considers both quantitative and qualitative information. A long-lived asset is deemed 
impaired when the future expected undiscounted cash flows from its use and disposition is less than the assets’ carrying value. 
Impairment is measured based on the estimated fair value, which is primarily 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 inputs used by management for fair value measurements include 
significant inputs that are not observable in the market and thus represent a Level 3 fair value measurement for these types of 
assets. In addition to the evaluations discussed above, specific events such as a reduction in economically recoverable reserves or 
production ceasing on a property for an extended period may require that a separate impairment evaluation be completed on a 
significant property.

(1)  The Partnership recorded $12.1 million of coal property impairments during the year ended December 31, 2016, primarily  
as a result of lease surrender and termination. The Partnership recorded $3.8 million of coal property impairment during 
the three months ended September 30, 2016 and the fair value of the impaired asset recorded at fair value was $4.0 million 
at September 30, 2016. The Partnership recorded $8.2 million of coal property impairment during the three months ended 
December 31, 2016 and the fair value of the impaired asset recorded at fair value was $0.0 million at December 31, 2016.  

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

Total  coal  property  impairment  expense  for  the  year  ended  December  31,  2014  was  $16.8  million. This  expense  was 
recorded during the fourth quarter of 2014 when management concluded certain unleased properties were impaired due 
primarily  to  the  ongoing  regulatory  environment  and  continued  depressed  coal  markets  with  little  indications  of 
improvement in the near term. The fair values for those unleased properties were determined for the associated reserves 
using Level 2 market approaches based upon recent comparable sales and Level 3 expected cash flows.

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

(3)  The Partnership recorded $1.7 million of aggregates royalty property impairments during the year ended December 31, 
2016.  Total  aggregates  property  impairment  expense  for  the  year  ended  December  31,  2015  was  $43.4  million.This 
impairment was recorded during the three months ended September 30, 2015. The fair value measurement of these impaired 
assets recorded at fair value was $13.1 million at September 30, 2015. This impairment primarily resulted from greenfield 
development projects that have not performed as projected, leading to recent lease concessions on minimums and royalties

combined with the continued regional market decline for certain properties. NRP compared net capitalized costs of its 
aggregates properties to estimated undiscounted future net cash flows. If the net capitalized cost exceeded the undiscounted 
cash flows, the Partnership recorded an impairment for the excess of net capitalized cost over fair value. A discounted cash 
flow model was used to estimate fair value. Significant inputs used to determine fair value include estimates of future cash 
flow, discount rate and useful economic life. Estimated cash flows are the product of a process that began with current 
realized pricing as of the measurement date and included an adjustment for risk related to the future realization of cash 
flows. Total aggregates property impairment expense for the year ended December 31, 2014 was $3.0 million. 

10.    Goodwill and Intangible Assets (Including Affiliate)

impairments on the Consolidated Statements of Comprehensive Income.

During the fourth quarter of 2014, $52.0 million of goodwill was added relating to the VantaCore acquisition. This amount 
represented the preliminary residual value. During 2015, the purchase price allocation was adjusted as more detailed analysis was 
completed and additional information was obtained about the facts and circumstances for VantaCore’s property, plant and equipment, 
right to mine assets and asset retirement obligations that existed as of the acquisition date. These adjustments decreased goodwill 
by $46.5 million and resulted in an acquisition date goodwill of $5.5 million. 

During the fourth quarter of 2015, the Partnership evaluated goodwill for impairment and compared the estimated fair value 
of the VantaCore reporting unit to its carrying amount. The carrying amount exceeded fair value and the Partnership recorded a  
$5.5  million  goodwill  impairment  expense  include  in  Asset  impairments  on  the  Partnership's  Consolidated  Statements  of 
Comprehensive Income. The lower fair value was primarily a result of the deterioration in certain regional markets in which 
VantaCore operates causing a decline in future performance levels compared to levels estimated during the purchase price allocation 
process. A discounted cash flow model was used to estimate fair value. Significant inputs used to determine fair value include 
estimates of future cash flow, discount rate and useful economic life. These estimates were based on current conditions and historical 
experience applied to develop projections of future operating performance.

NRP LP Debt

NRP 2018 Senior Notes    

In September 2013, the Partnership, together with NRP Finance Corporation ("NRP Finance"), a wholly owned subsidiary 
of the Partnership, as co-issuer, issued $300.0 million of 9.125% Senior Notes at an offering price of 99.007% of par (the "NRP 
2018 Senior Notes"). Net proceeds after expenses from the issuance of NRP 2018 Senior Notes were approximately $289.0 million. 
The NRP 2018 Senior Notes call for semi-annual interest payments on April 1 and October 1 of each year, and will mature on 
October 1, 2018. None of the Partnership's subsidiaries guarantee the NRP 2018 Senior Notes.

In October 2014, the Partnership, together with NRP Finance as co-issuer, issued an additional $125.0 million of the NRP 
2018 Senior Notes at an offering price of 99.5% of par. The additional issuance constituted the same series of securities as the 
existing NRP 2018 Senior Notes. Net proceeds of $122.6 million from the additional issuance of the NRP 2018 Senior Notes were 
used to fund a portion of the purchase price of NRP’s acquisition of non-operated working interests in oil and gas assets located 
in the Williston Basin in North Dakota. 

The Partnership and NRP Finance have the option to redeem the NRP 2018 Senior Notes, in whole or in part, at any time 
on or after April 1, 2016, at fixed redemption prices specified in the indenture governing the NRP 2018 Senior Notes (the "2018 
Indenture"). The 2018 Indenture contains covenants that, among other things, limit the ability of the Partnership and certain of its 
subsidiaries to incur or guarantee additional indebtedness. Under the 2018 Indenture, the Partnership and certain of its subsidiaries 
generally are not permitted to incur additional indebtedness unless, on a consolidated basis, the fixed charge coverage ratio (as 
defined in the indenture) is at least 2.0 to 1.0 for the four preceding full fiscal quarters. The ability of the Partnership and certain 
of its subsidiaries to incur additional indebtedness is further limited in the event the amount of indebtedness of the Partnership and 
certain of its subsidiaries that is senior to the Partnership's unsecured indebtedness exceeds certain thresholds.

Opco Debt

All of Opco’s debt is guaranteed by its wholly owned subsidiaries and is secured by certain of the assets of Opco and its 
wholly owned subsidiaries other than NRP Trona LLC, as further described below. As of December 31, 2016 and 2015, Opco was 
in compliance with the terms of the financial covenants contained in its debt agreements.

Opco Credit Facility

In June 2016, Opco entered into the first amendment (the "First Amendment") to its Amended and Restated Credit Agreement 
(the "Opco Credit Facility") that is guaranteed by all of Opco’s wholly owned subsidiaries, and is secured by liens on certain of 
the assets of Opco and its subsidiaries, as further described below. Under the First Amendment:

•  The maturity date of the Opco Credit Facility was extended from October 1, 2017 to June 30, 2018; 

•  The maximum leverage ratio of consolidated indebtedness to consolidated EBITDDA (as defined in the Opco Credit 

Facility) has been amended to remain at 4.0x for the remaining term of the Opco Credit Facility;

•  The asset sale covenant was amended to allow asset sales of up to $300.0 million from and after the effective date of 
the First Amendment; provided, however, that 75% of the net cash proceeds of any such asset sales must be used to 
repay the Opco Credit Facility (without any corresponding commitment reduction) and/or NRP Opco’s Senior Notes 
described below.   

On the effective date of the First Amendment, the total commitment under the Opco Credit Facility was reduced from $300.0 
million to $260.0 million. In addition, Opco and the lenders agreed to further reduce commitments under the Opco Credit Facility 
to (a) $210.0 million on December 31, 2016, (b) $180.0 million on June 30, 2017 and (c) $150.0 million on December 31, 2017. 
Opco will have the right to delay any of these commitment reductions by up to 90 days each upon the agreement of the lenders 
holding 66.7% of the then-existing commitments. To the extent any such commitment reduction is extended under the terms of 
the A&R Revolving Credit Facility, Opco's ability to make distributions to the Partnership will be limited to amounts necessary 
for the Partnership to pay taxes and other general partnership expenses and make interest payments on its 9.125% Senior Notes 
due 2018.

96

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

In addition to the 4.0x leverage ratio described above, the Opco Credit Facility requires Opco to maintain a 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. As of December 31, 2016, Opco's leverage ratio was 2.80x, and fixed charge coverage ratio was 4.99x.   

Effective on the date of the First Amendment, indebtedness under the Opco Credit Facility bears interest, at Opco's option, 

at:

• 

• 

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

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

The  weighted  average  interest  rates  for  the  borrowings  outstanding  under  the  Opco  Credit  Facility  for  the  years  ended 

December 31, 2016 and 2015 were 4.46% and 2.91%, respectively.

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 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. The Opco Credit Facility also contains customary events of default, including cross-defaults under Opco’s senior notes 
(as described below).

The Opco Credit Facility is collateralized and secured by liens on certain of Opco’s assets with carrying values of $673.0 
million and $709.9 million classified as Land, Plant and equipment and Mineral rights on the Partnership’s Consolidated Balance 
Sheet as of December 31, 2016 and 2015, respectively. The collateral includes (1) the equity interests in all of Opco’s wholly 
owned subsidiaries, other than NRP Trona LLC (which owns a 49% non-controlling equity interest in Ciner Wyoming), (2) the 
personal property and fixtures owned by Opco’s wholly owned subsidiaries, other than NRP Trona LLC, (3) Opco’s material coal 
royalty revenue producing properties, (4) real property associated with certain of VantaCore’s construction aggregates mining 
operations, and (5) certain of Opco’s coal-related infrastructure assets.

Opco Senior Notes   

Opco has issued several series of private placement senior notes (the "Opco Senior Notes") with various interest rates and 
principal due dates. As of December 31, 2016 and 2015, the Opco Senior Notes had cumulative principal balances of $503.0 
million and $585.9 million, respectively. Opco made principal payments of $82.9 million on the Opco Senior Notes during the 
year ended December 31, 2016 and $80.8 million for the years ended December 31, 2015 and 2014.

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.

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, 2016. As of December 31, 2016, Opco's 
leverage ratio was 2.80x, and fixed charge coverage ratio was 4.99x.

•  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.

NRP Oil and Gas Debt Classified as Liabilities of Discontinued Operations

RBL Facility    

In August 2013, NRP Oil and Gas entered into the RBL Facility, a senior secured, reserve-based revolving credit facility, in 
order to fund capital expenditure requirements related to the development of the oil and gas assets in which it owned non-operated 
working interests. The RBL Facility was secured by a first priority lien and security interest in substantially all of the assets of 
NRP Oil and Gas. NRP Oil and Gas was the sole obligor under the RBL Facility, and neither the Partnership nor any of its other 
subsidiaries was a guarantor of the RBL Facility.

At December 31, 2015, there was $85.0 million respectively, outstanding under the RBL Facility. As described in Note 3. 
Discontinued Operations, the Partnership included this debt and its related interest expense in discontinued operations. In July 
2016, NRP Oil and Gas LLC closed the sale of its non-operated oil and gas working interest assets and used a portion of the 
proceeds to repay the RBL Facility in full.

of market rates and the terms of the credit facility allow the Partnership to repay this debt at any time without penalty.

13.    Related Party Transactions

Reimbursements to Affiliates of our General Partner

The Partnership’s general partner does not receive any management fee or other compensation for its management of Natural 
Resource Partners L.P. However, in accordance with the partnership agreement, the general partner and its affiliates are reimbursed 
for services provided to the Partnership and for expenses incurred on the Partnership’s behalf. Employees of Quintana Minerals 
Corporation ("QMC") and Western Pocahontas Properties Limited Partnership ("WPPLP"), affiliates of the Partnership, provide 
their services to manage the Partnership's business. QMC and WPPLP charge the Partnership the portion of their employee salary 
and  benefits  costs  related  to  their  employee  services  provided  to  NRP.  In  addition,  the  Partnership  receives  non-cash  equity 
contributions from its general partner related to compensation paid directly by the general partner and not reimbursed by the 
Partnership.  These amounts are presented as non-cash equity contributions on the Partnership's Consolidated Statements of Partners' 
Capital and were $0.3 million and $0.8 million during the years ended December 31, 2016 and 2015, respectively. These QMC 
and WPPLP employee management service costs and non-cash equity compensation expenses are presented as Operating and 
maintenance  expenses—affiliates,  net  and  General  and  administrative—affiliates  on  the  Consolidated  Statements  of 
Comprehensive Income. NRP also reimburses overhead costs incurred by its affiliates to manage the Partnership's business. These 
overhead costs include certain rent, legal, accounting, treasury, information technology, insurance, administration of employee 
benefits and other corporate services incurred by or on behalf of the Partnership’s general partner and its affiliates and are presented 
as Operating and maintenance expenses—affiliates, net and General and administrative—affiliates on the Consolidated Statements 
of Comprehensive Income. 

The Partnership had Accounts payable—affiliates to QMC of $0.4 million and $1.1 million, including less than $0.1 million
and $0.6 million related to discontinued operations at December 31, 2016 and 2015, respectively, for services provided by QMC 
to the Partnership.  The Partnership had Accounts payable—affiliates to WPPLP of $0.6 million and $0.3 million at December 31, 
2016 and 2015, respectively.

Cline Affiliates 

Various companies affiliated with Chris Cline, including Foresight Energy LP, lease coal reserves from the Partnership, and 
the Partnership also leases coal transportation assets to them for a fee. Mr. Cline, both individually and through another affiliate, 
Adena Minerals, LLC, owns a 31% interest (unaudited) in the NRP's general partner, as well as approximately 0.5 million of NRP's 
common units (unaudited) at December 31, 2016. 

Coal related revenues from Foresight Energy totaled $63.4 million, $86.6 million and $81.5 million for the years ended 
December 31, 2016, 2015 and 2014, respectively. As of December 31, 2016 and 2015, the Partnership had Accounts receivable
—affiliates from Foresight Energy of $6.5 million and $6.4 million, respectively. As of December 31, 2016 and 2015, the Partnership 
had received $71.6 million and $82.6 million, respectively in minimum royalty payments to date that have been recorded as 
Deferred revenue—affiliates since they have not been recouped by Foresight Energy.

NRP owns and leases rail load out and associated facilities to Foresight Energy at Foresight Energy's Sugar Camp mine.  The 
lease agreement is accounted for as a direct financing lease.  Total projected remaining payments under the lease at December 31, 
2016 were $76.4 million with unearned income of $31.8 million, and the net amount receivable was $44.6 million, of which $2.2 
million is included in Accounts receivable—affiliates while the remaining is included in Long-term contracts receivable—affiliate 
on the accompanying Consolidated Balance Sheets. Minimum lease payments are $5.0 million per year for the next five years and 
represent a $1.25 million per quarter in deficiency payment. Total projected remaining payments under the lease at December 31, 
2015 were $81.2 million with unearned income of $35.4 million and the net amount receivable was $45.9 million, of which $2.0 
million is included in Accounts receivable—affiliates while the remaining is included in Long-term contracts receivable—affiliates 
on the accompanying Consolidated Balance Sheets. 

NRP holds a contractual overriding royalty interest from a subsidiary of Foresight Energy that provides for payments based 
upon production from specific tons at Foresight Energy's Sugar Camp operations. This overriding royalty was accounted for as a 
financing arrangement and is reflected as an affiliate receivable. The net amount receivable under the agreement as of December 31, 
2016 was $2.7 million, of which $1.4 million is included in Accounts receivable—affiliates while the remaining is included in 
Long-term contracts receivable—affiliate.  The net amount receivable under the agreement as of December 31, 2015 was $4.9 
million, of which $1.5 million is included in Accounts receivable—affiliates while the remaining is included in Long-term contracts 
receivable—affiliate on the accompanying Consolidated Balance Sheets.

NRP owns rail load out transportation assets and subcontracts out the operating responsibilities to an affiliate of Foresight 
Energy at Foresight's Williamson mine. During the years ended December 31, 2016, 2015 and 2014, the Partnership recorded 
operating and maintenance expenses—affiliates of $1.3 million, $1.4 million and $1.6 million, respectively, to operate these assets. 

During the years ended December 31, 2016, 2015 and 2014, the Partnership recognized a gain of $0.0 million, $9.3 million
and $5.7 million, respectively on a reserve swap at Foresight Energy's Williamson mine. The gain is included in Coal royalty and 
other—affiliates revenues on the Consolidated Statements of Comprehensive Income. The Level 3 fair value of the reserves was 
estimated  using  a  discounted  cash  flow  model.   The  expected  cash  flows  were  developed  using  estimated  annual  sales  tons, 
forecasted sales prices and anticipated market royalty rates.

Long-Term Debt—Affiliate

Donald R. Holcomb, one of the Partnership’s former directors, was a manager of Cline Trust Company, LLC (the "Cline 
Trust Company"). As of December 31, 2015, Cline Trust Company owned approximately 0.5 million of the Partnership’s common 
units and $20.0 million in principal amount of the Partnership’s 9.125% Senior Notes due 2018. As of December 31, 2015, the 
members of the Cline Trust Company were four trusts for the benefit of the children of Chris Cline, each of which owns an 
approximately equal membership interest in the Cline Trust Company.  As of December 31, 2015, Mr. Holcomb also served as 
trustee of each of the four trusts. The balance on this portion of the Partnership’s 9.125% Senior Notes due 2018 was $19.9 million
as of December 31, 2015 and was included in Long-term debt, net—affiliate on the accompanying Consolidated Balance Sheet. 
In April 2016, Mr. Holcomb resigned from the Partnership's board of directors and as a result the $19.9 million debt balance held 
by Cline Trust Company was subsequently reclassified as Long-term debt, net on the Partnership's accompanying Consolidated 
Balance Sheet.

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, 2016, a fund controlled by Quintana Capital owned a majority interest in Corsa Coal Corp ("Corsa")., a 
coal mining company traded on the TSX Venture Exchange that is one of the Partnership’s lessees in Tennessee. Corbin J. Robertson 
III, one of the Partnership’s directors, is Chairman of the Board of Corsa. Coal related revenues from Corsa totaled $2.2 million, 
$3.1 million and $3.0 million for the years ended December 31, 2016, 2015 and 2014, respectively.

As of December 31, 2016 and 2015 the Partnership had recorded $0.0 million and $0.3 million, respectively in minimum 
royalty payments to date as Deferred revenue—affiliates since they have not been recouped by Corsa.  The Partnership also had 
Accounts receivable—affiliates totaling $0.2 million and $0.2 million from Corsa at December 31, 2016 and 2015, respectively.

WPPLP Production Royalty and Overriding Royalty

For the year ended December 31, 2016, the Partnership recorded $0.7 million in operating and maintenance expenses—
affiliates related to a non-participating production royalty payable to WPPLP pursuant to a conveyance agreement entered into in 
2007.  These charges were $0.4 million and zero for the years ended December 31, 2015 and 2014, respectively. The Partnership 
had Other assets—affiliate from WPPLP of $1.0 million and $1.1 million at December 31, 2016 and December 31, 2015, respectively 
related to a non-production royalty receivable from WPPLP for overriding royalty interest on a mine.

14.    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.

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 had been closed, the property had been reclaimed, and the state reclamation bond had 
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. A subsidiary of the Partnership has been named as a defendant in one of these lawsuits. The 
Partnership currently cannot reasonably estimate a range of potential loss, if any, related to this matter.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—CONTINUED

Foresight Energy Disputes 

In November 2015, we filed a lawsuit against Foresight Energy’s subsidiary, Hillsboro Energy LLC ("Hillsboro"), in the 
Circuit Court of the Fourth Judicial Circuit in Montgomery County, Illinois. The lawsuit alleges, among other items, breach of 
contract by Hillsboro resulting from a wrongful declaration of force majeure at Hillsboro’s Deer Run mine in July 2015. In late 
March 2015, elevated carbon monoxide readings were detected at the Deer Run mine, and coal production at the mine was idled. 
In July 2015, we received the notice declaring a force majeure event at the mine as a result of the elevated carbon monoxide levels. 
We believe the force majeure claim by Hillsboro has no merit and we are vigorously pursuing recovery against them. However, 
the effect of a valid force majeure declaration would relieve Foresight Energy of its obligation to pay us minimum deficiency 
payments of $7.5 million per quarter, or $30.0 million per year. Foresight Energy's failure to make the deficiency payment with 
respect to 2015 and 2016 resulted in a cumulative $46.0 million negative cash impact to us. Such amount will increase for each 
quarter during which mining operations continue to be idled. We do not currently have an estimate as to when the mine will resume 
coal production. If the mine remains idled for an extended period or if the mine is permanently closed, our financial condition 
could be adversely affected.

In April 2016, we filed a lawsuit against Macoupin Energy, LLC ("Macoupin"), a subsidiary of Foresight Energy, in Macoupin 
County, Illinois. The lawsuit alleges that Macoupin has failed to comply with the terms of its coal mining, rail loadout and rail 
loop  leases  by  incorrectly  recouping  previously  paid  minimum  royalties.  Foresight  Energy’s  failure  to  properly  calculate  its 
recoupable balance and failure to make payments in accordance with these lease agreements has resulted in a cumulative $6.2 
million negative cash impact to us. While the Partnership plans to pursue its claim, a valuation allowance for the receivable amount 
has been recorded.

Environmental Compliance

The operations the Partnership’s lessees conduct on its properties, as well as the aggregates/industrial minerals and oil and 
gas operations in which the Partnership has interests, are subject to federal and state environmental laws and regulations. See "Item 
1. Business—Regulation and Environmental Matters." As an owner of surface interests in some properties, the Partnership may 
be liable for certain environmental conditions occurring on the surface properties. The terms of substantially all of the Partnership’s 
coal leases require the lessee to comply with all applicable laws and regulations, including environmental laws and regulations. 
Lessees post reclamation bonds assuring that reclamation will be completed as required by the relevant permit, and substantially 
all of the leases require the lessee to indemnify the Partnership against, among other things, environmental liabilities. Some of 
these indemnifications survive the termination of the lease. The Partnership makes regular visits to the mines to ensure compliance 
with lease terms, but the duty to comply with all regulations rests with the lessees. The Partnership believes that its lessees will 
be able to comply with existing regulations and does not expect that any lessee’s failure to comply with environmental laws and 
regulations to have a material impact on the Partnership’s financial condition or results of operations. The Partnership has neither 
incurred, nor is aware of, any material environmental charges imposed on the Partnership related to its properties for the period 
ended December 31, 2016. 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 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. The Partnership is also responsible for losses and liabilities, including environmental 
liabilities that may arise from uninsured and underinsured events at its VantaCore operations.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—CONTINUED

The Partnership had a significant concentration of revenues with Foresight Energy and Alpha Natural Resources. The exposure 
is currently spread out over a number of different mining operations and leases. During the year ended December 31, 2015, total 
revenues and other income from Alpha Natural Resources included a $6.0 million non-recurring lease assignment fee.    

16.    Unit-Based Compensation 

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

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

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

A summary of activity in the outstanding grants during 2016 is as follows (in thousands):

Grants typically vest at the end of a four-year period and are paid in cash upon vesting. The Partnership recorded a credit to 
general and administrative expenses related to its Long-Term Incentive Plan of $3.4 million for the year ended December 31, 2015, 
due to the decline in the market price of the Partnership's common units during 2015. For the years ended December 31, 2016 and 
2014 the Partnership recorded G&A expenses of $1.4 million and $1.0 million, respectively. 

In connection with the Long-Term Incentive Plans, payments are typically made during the first quarter of the year. Payments 
of $1.5 million, $4.4 million and $6.5 million were made during the years ended December 31, 2016, 2015, and 2014, respectively. 
The grant date fair value was $0.0 million, $4.2 million and $6.6 million for awards in 2016, 2015 and 2014, respectively. The 
unaccrued cost associated with unvested outstanding grants and related DERs at December 31, 2016 and December 31, 2015, was 
$0.8 million and $0.7 million, respectively.

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

Lease Modifications, Termination and Forfeitures of Minimum Royalty Balances

During the year ended December 31, 2016, the Partnership entered into agreements with certain lessees to either modify or 

terminate existing coal related leases that resulted in the Partnership recognizing $40.5 million of deferred revenue as follows:

•  An agreement that terminated a central Appalachia coal royalty lease and resulted in the lessee forfeiting the right to 
recoup $26.2 million of minimum royalties previously paid to the Partnership. The Partnership agreed to transfer its coal mineral 
rights that were subject to this former lease to the lessee. This terminated lease had no current or planned production and the 
mineral rights transferred had zero net book value on the Partnership's consolidated Balance Sheets as of March 31, 2016. As a 
result of this transaction, in April 2016 the Partnership recognized $26.2 million of revenue.

•  Lease modifications, terminations and forfeitures of existing coal royalty and other leases resulted in lessee forfeiture of 
rights to recoup previously paid minimum royalties and the reduction in lessee recoupment time. As a result of these modifications, 
in the first and second quarters of 2016 the Partnership recognized $10.7 million of revenue.

•  The  Partnership  recognized  $3.6  million  of  revenue  from  various  other  coal  and  aggregates  lease  modifications, 

terminations and forfeitures during the year ended December 31, 2016.

During the years ended December 31, 2015 and 2014, there was less than $0.1 million and $1.4 million of revenue recognized 

from coal and aggregate lease modifications, terminations or forfeitures, respectively.

19.    Subsequent Events

The  following  represents  material  events  that  have  occurred  subsequent  to  December 31,  2016  through  the  time  of  the 

Partnership’s filing of its Annual Report on Form 10-K with the SEC:

Distribution Declared

On  February 14, 2017, the Partnership paid a distribution of $0.45 per unit to unitholders of record on February 7, 2017. 

Recapitalization Transactions

On March 2, 2017, the Partnership completed the following recapitalization transactions:

Issuance of Preferred Units and Warrants

NRP issued $250 million of Class A Convertible Preferred Units representing limited partner interests in NRP (the "Preferred 
Units") to Blackstone and 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 dividends 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"). 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.  

The Preferred Units have a perpetual term, unless converted or redeemed as described below. The Preferred Units (including 
any PIK Units) are convertible into common units at the election of the holders (1) after the fifth anniversary and prior to the eighth 
anniversary of the issue date at a 7.5% discount to the volume weighted average trading price of our common units (the "VWAP") 
for the 30 trading days immediately prior to the notice of conversion if the 30-day VWAP immediately prior to such notice is 
greater than $51.00 (subject to a maximum of 33% of the Preferred Units per year) and (2) after the eighth anniversary of the issue 
date at a 10% discount to the VWAP for the 30 trading days immediately prior to the notice of conversion. Instead of issuing 
common units pursuant to clause (1) of the preceding sentence, NRP has the option to redeem the Preferred Units proposed to be 
converted for cash at a price equal to the Per Unit Purchase Price, plus the value of any accrued and unpaid distributions. To the 
extent the holders of the Preferred Units have not elected to convert their Preferred Units by the twelfth anniversary of the issue 
date, NRP has the right to force conversion of the Preferred Units into common units at a 10% discount to the VWAP for the 30 
105

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

trading days immediately prior to the notice of conversion. In addition, NRP has the ability to redeem at any time (subject to 
compliance with our debt agreements) all or any portion of the Preferred Units (including PIK Units) for cash at the agreed upon 
per unit amount, which is calculated as the Per Unit Purchase Price multiplied by (i) prior to the third anniversary of the closing 
date, 1.50, (ii) on or after the third anniversary of the closing date and prior to the fourth anniversary of the closing date, 1.70 and 
(iii) on or after the fourth anniversary of the closing date, 1.85.  

The terms of the Preferred Units contain certain restrictions on our ability to pay distributions on our common units. To the 
extent that either (i) our consolidated Leverage Ratio (as defined in the Restated Partnership Agreement) is greater than 3.25x, or 
(ii) the ratio of our Distributable Cash Flow 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, including:

• 

the incurrence of new indebtedness, subject to certain exceptions; 

•  material changes to NRP’s business; 

• 

• 

• 

• 

acquisitions and divestitures in excess of certain dollar thresholds;

amendments to material contracts resulting in a cash impact to NRP in excess of certain dollar thresholds;

settlement of any litigation or regulatory matter resulting in cash payments by NRP in excess of certain thresholds; 
and

amendments to related party contracts outside of the ordinary course of business.  

GoldenTree also has more limited approval rights that will expand once Blackstone's ownership goes below the Minimum 
Preferred Unit Threshold (as defined below). The Preferred Purchaser Approval Rights are not transferrable without NRP's consent.  
In addition, the Preferred Purchaser 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").  To the extent any Preferred Units that have converted into common units are still held by 
the applicable Preferred Purchaser (or its affiliates), such common units will be deemed to represent a number of Preferred Units 
based on the weighted average number of common units issued in each conversion and will count towards the Minimum Preferred 
Unit Threshold.  

The foregoing terms of the Preferred Units are reflected in our Fifth Amended and Restated Agreement of Limited Partnership, 
dated as of March 2, 2017, which is filed as Exhibit 3.2 to this Annual Report on Form 10-K and incorporated herein by reference. 
The terms of the Warrants are reflected in the Form of Warrant to Purchase Common Units filed as Exhibit 4.28 to this Annual 
Report on Form 10-K, which is incorporated herein by reference.

At the closing, pursuant to a Board Representation and Observation Rights Agreement, the Preferred Purchasers received 
certain board appointment and observation rights and appointed one director and one observer to the Board of Directors of GP 
Natural Resource Partners LLC.  For more information on these rights, see "Certain Relationships and Related Transactions, and 
Director Independence—Board Representation and Observation Rights Agreement."  

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. If the shelf registration statements are not effective by the 

106

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

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.

Opco Credit Facility Amendment

NRP entered into the Second Amendment to Opco’s Third Amended and Restated Credit Agreement to extend the term 
thereof until April 2020, and reduced the commitments of the lenders to $180 million (from $210 million) effective at the closing 
of the recapitalization transactions.  Pursuant the Second Amendment, commitments under the Opco Credit Facility will be reduced 
to $150 million at December 31, 2017 and further reduced to $100 million at December 31, 2018 through maturity in April 2020.  
The amendment does not change the pricing grid or financial covenants under the Opco Credit Facility; 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.  Other  terms  of  the  Second Amendment  include 
revisions to the mandatory prepayment provisions with respect to net cash proceeds received from certain asset sales and additional 
limitations on the ability of Opco and its subsidiaries to make certain investments. The Second Amendment is filed as Exhibit 
10.14 to this Annual Report on Form 10-K and is incorporated herein by reference.

Issuance of 2022 Notes; Exchange and Redemption of 2018 Notes 

NRP and NRP Finance issued $346 million aggregate principal amount of 10.500% Senior Notes due 2022 to several holders 
of its 2018 Notes. Of the $346 million of 2022 Notes issued, $241 million in aggregate principal amount were issued in exchange 
for $241 million in aggregate principal amount of 2018 Notes, and $105 million of the 2022 Notes were issued to the holders in 
exchange for cash.  The 2022 Notes are issued under an Indenture dated as of March 2, 2017 (the "2022 Indenture"), bear interest 
at 10.500% per year, are payable semi-annually on March 15 and September 15, beginning September 15, 2017, and mature on 
March 15, 2022.

NRP and NRP Finance have the option to redeem the 2022 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 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 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 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 Notes 
may require us to purchase their 2022 Notes at a purchase price equal to 101% of the principal amount of the 2022 Notes, plus 
accrued and unpaid interest, if any.  The 2022 Notes purchased for cash were issued at a price of 98.75% (original issue discount 
of 1.25%), and each holder exchanging 2018 Notes received a fee of 5.813% of the aggregate principal amount of all 2018 Notes 
tendered for exchange by such holder, as well as all accrued and unpaid interest thereon.

The 2022 Indenture contains restrictive covenants that are substantially similar to those contained in the Indenture governing 
the 2018 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 we have 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 the form of cash, unless, in each case, our 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 Notes are the senior unsecured obligations of NRP and NRP Finance. The 2022 Notes rank equal in right of payment 
to all existing and future senior unsecured debt of NRP and NRP Finance, including the remaining outstanding 2018 Notes, and 
senior in right of payment to any of NRP's subordinated debt.  The 2022 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 

107

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

structurally subordinated in right of payment to all existing and future debt and other liabilities of our subsidiaries, including the 
Opco Credit Facility and each series of Opco’s existing senior notes.  None of NRP's subsidiaries guarantee the 2022 Notes.

The terms of the 2022 Notes are more fully described in the 2022 Indenture, which is filed as Exhibit 4.24 to this Annual 

Report on Form 10-K and incorporated herein by reference.

NRP entered into a registration rights agreement (the "Notes Registration Rights Agreement") with the holders of the 2022 
Notes, pursuant to which we and NRP Finance agreed to file a registration statement with the Securities and Exchange Commission 
for the benefit of the holders of the 2022 Notes so that such holders can exchange the 2022 Notes for exchange securities that have 
substantially identical terms as the 2022 Notes. NRP and NRP Finance agreed to use commercially reasonable efforts to cause the 
exchange to be completed within 180 days after the closing and will be required to pay additional interest, as specified in the Notes 
Registration Rights Agreement, if NRP fails to comply with its obligations to register the 2022 Notes within the specified time 
periods.

NRP expects to redeem $90 million in aggregate principal amount of the 2018 Notes at a redemption price of 104.563%, 
and pay all accrued and unpaid interest thereon, in April 2017.  In addition, NRP is required to redeem any and all remaining 
outstanding 2018 Notes (and pay accrued and unpaid interest thereon) within 60 days after October 1, 2017.

Estimated Proved Reserves

Proved reserves are those quantities of crude oil and natural gas, which, by analysis of geoscience and engineering data, can 
be estimated with reasonable certainty to be economically producible from a given date forward, from known reservoirs, and under 
existing economic conditions, operating methods, and government regulations prior to the time at which contracts providing the 
right to operate expire, unless evidence indicates renewal is reasonably certain. In connection with the estimation of proved reserves, 
the term "reasonable certainty" implies a high degree of confidence that the quantities of crude oil, natural gas liquids and/or natural 
gas actually recovered will equal or exceed the estimate. The Partnership estimated proved reserves as of December 31, 2015 and 
2014 were prepared by a third party independent reserve engineer. To achieve reasonable certainty, the third party engineer employed 
technologies that have been demonstrated to yield results with consistency and repeatability. The technologies and economic data 

109

 
 
NATURAL RESOURCE PARTNERS L.P.
SUPPLEMENTAL INFORMATION ON OIL AND GAS EXPLORATION AND PRODUCTION ACTIVITIES
(Unaudited)

used in the estimation of the Partnership’s proved reserves include, but are not limited to, well logs, geologic maps including 
isopach and structure maps, analogy and statistical analysis, and available downhole and production data and well test data. The 
third party engineer prepared its report covering properties representing 100% of the Partnership’s estimated proved reserves as 
of December 31 2015 and 2014. Prices were calculated using the unweighted average of the first-day-of-the-month pricing for the 
twelve months ended December 31, 2015 and 2014. These prices were then adjusted for transportation and other costs. There can 
be no assurance that the proved reserves will be produced as estimated or that the prices and costs will remain constant. There are 
numerous uncertainties inherent in estimating reserves and related information and different reserve engineers often arrive at 
different estimates for the same properties.

The following table shows our estimated domestic proved reserves and reserve additions and revisions:

(1)  As a result of the sale of its non-operated oil and gas working interest business effective April 1, 2016, the Partnership

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, 2016. 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, 2016 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, 2016 
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, our management concluded that our internal control 
over financial reporting was effective as of December 31, 2016. 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.

We have audited Natural Resource Partners L.P.’s internal control over financial reporting as of December 31, 2016, 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). Natural Resource Partners L.P.’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 company’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United 
States). 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.

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 

114

 
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.

In our opinion, Natural Resource Partners L.P. maintained, in all material respects, effective internal control over financial 

reporting as of December 31, 2016, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), 
the consolidated balance sheets of Natural Resource Partners L.P. as of December 31, 2016 and 2015, and the related consolidated 
statements  of  comprehensive  income  (loss),  partners’  capital  and  cash  flows  for  each  of  the  three  years  in  the  period  ended 
December 31, 2016 and our report dated March 6, 2017 expressed an unqualified opinion there thereon.

Corporate Governance

Board Meetings and Executive Sessions

The Board met 16 times in 2016.  During 2016, our non-management directors met in executive session several times. The 
presiding  director  was  Mr. Blakely,  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 2016. Mr. Blakely 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.

In April 2016, Donald R. Holcomb resigned from the Board of Directors of GP Natural Resource Partners LLC, and L.G. 

(Trey) Jackson, III was appointed to the Board. In March 2017, Jasvinder Khaira was appointed to the Board by Blackstone.

Independence of Directors

The Board of Directors has affirmatively determined that Messrs. Blakely, Gordy, Karn, Navarre, Smith and Vecellio are 
independent based on all facts and circumstances considered by the Board, including the standards set forth in Section 303A.02
(a)  of  the  NYSE’s  listing  standards. Although  we  had  a  majority  of  independent  directors  in  2016,  because  we  are  a  limited 
partnership as defined in Section 303A of the NYSE’s listing standards, we are not required to do so. The Board has an Audit 
Committee, a Compensation, Nominating and Governance Committee, and a Conflicts Committee, each of which is staffed solely 
by independent directors.

Audit Committee

Our Audit Committee is comprised of Robert B. Karn III, who serves as chairman, Robert T. Blakely, Richard A. Navarre 
and Stephen P. Smith. Mr. Karn, Mr. Blakely, Mr. Navarre and Mr. Smith are "Audit Committee Financial Experts" as determined 
pursuant to Item 407 of Regulation S-K. During 2016, the Audit Committee met seven times.

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 2016, 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, 2016 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 

120

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 2016 was compatible with the auditors’ independence.

In performing all of these functions, the Audit Committee acts only in an oversight capacity. The Audit Committee reviews 
our  Quarterly  Reports  on  Form 10-Q  and Annual  Reports  on  Form 10-K  prior  to  filing  with  the  Securities  and  Exchange 
Commission. In 2016, 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, 2016, for filing with the Securities and Exchange Commission.

Compensation, Nominating and Governance Committee

Executive officer compensation is administered by the CNG Committee, which is comprised of four members. Mr. Blakely, 
the Chairman, has served on the CNG Committee since 2003. Mr. Karn has served on the CNG Committee since 2002. Mr. Vecellio 
joined the Committee in 2007, and Mr. Gordy joined the CNG Committee in 2013. 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 2016, the CNG Committee met four 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

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 2015, and we believe that 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 2016.

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. We have no employees, other than at the VantaCore operations, and our executive officers based in 
Houston, Texas are employed by Quintana Minerals Corporation and our executive officers based in Huntington, West Virginia 
are employed by Western Pocahontas Properties Limited Partnership, both of which are our affiliates.  For a more detailed description 
of our structure, see "Item 1. Business—Partnership Structure and Management" in this Annual Report on Form 10-K. Although 
our executives’ salaries and bonuses are paid directly by the private companies that employ them, we reimburse those companies 
based on the time allocated to NRP by each executive officer. Our reimbursement for the compensation of executive officers is 
governed by our partnership agreement. 

Executive Officer Compensation Strategy and Philosophy

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

The 2016 compensation for executive officers consisted of four primary components:

base salaries;

annual cash incentive awards, including cash payments made by our general partner based on the cash distributions it 
receives from the common units that it owns (which we refer to herein as "GP Bonus Awards");

long-term equity and cash incentive compensation; and

perquisites and other benefits.

• 

• 

• 

• 

In December 2015, our CNG Committee reviewed the performance of the executive officers and the amount of time expected 
to be spent by each NRP officer on NRP business, and determined the salaries for each officer for 2016.  All of our named executive 
officers, other than Corbin J. Robertson, Jr., our Chairman and Chief Executive Officer and Kathryn S. Wilson, our Vice President, 
General Counsel and Secretary, spent 100% of their time on NRP matters during 2016, and NRP bears the cost of their time.  
Mr. Robertson has historically spent approximately 50% of his time on NRP matters.  Mr. Robertson does not receive a salary or 
an annual bonus in his capacity as Chief Executive Officer. Rather, Mr. Robertson has historically been compensated exclusively 
through long-term incentive awards and through GP Bonus Awards.  Mr. Robertson also directly or indirectly owns in excess of 
20% of the outstanding common units of NRP, and thus his interests are directly aligned with our unitholders.  In 2016, Ms. Wilson 
spent approximately 94% of her time on NRP matters and the rest of her time on private Robertson family owned company matters, 
and her time has been allocated to NRP accordingly.

Historically, in February of each year, the CNG Committee has approved the year-end bonuses for the year just ended and 
long-term incentive awards for the executive officers. The CNG Committee considers the performance of the partnership, the 
performance of the individuals and the outlook for the future in determining the amounts of the awards.  Because we are a partnership, 
tax and accounting conventions make it more costly for us to issue additional common units or options as incentive compensation. 
Consequently, we have no outstanding options or restricted units and currently have no plans to issue options or restricted units 
in the future.  Instead, prior to 2016, we issued phantom units, coupled with tandem distribution equivalent rights ("DERs"), to 
our executive officers that are paid in cash based on the average closing price of our common units for the 20-day trading period 
prior to vesting.  The phantom units and DERs typically vest four years from the date of grant.  In past years, these awards have 
served to align the executive officers’ interests with those of our unitholders.

123

During 2015, given the sharp decline in NRP’s unit price, the Board of Directors recognized that the value of the executive 
officers’ phantom unit awards and the decreased GP Bonus Awards no longer provided long-term incentive or retention value to 
management.  Accordingly, the Board authorized and directed the CNG Committee to begin a review of options for a new long-
term incentive program for NRP management to be adopted in 2016.  Upon the conclusion of this review, in February 2016, the 
CNG Committee elected not to award additional phantom units under the long-term incentive plan and instead adopted a new cash 
long-term incentive plan and recommended the new plan and forms of award agreements thereunder to the Board for approval.  
The Board approved the new plan and awards in February 2016 and approved awards to officers under the plan in March 2016. 
In March 2017, the Board determined that the conditions to the vesting of the performance awards had been met as a result of the 
completion of the 2017 recapitalization transactions described elsewhere in this Annual Report on Form 10-K. See "—Evaluation 
of 2016 Performance; Components of Compensation-Long-Term Incentive Compensation-2016 Cash Long-Term Incentive Plan" 
below.

In light of the recently completed recapitalization transactions, the CNG Committee is evaluating a new long-term incentive 
program that best reflects the current outlook for NRP.  Accordingly, no long-term incentive awards have yet been made during 
2017.  The CNG Committee and the Board may determine to award additional cash incentive awards, phantom unit awards or 
other forms of long-term incentive compensation during 2017.

Role of Compensation Experts

Historically, the CNG Committee periodically has utilized consultants to get a basic sense of the market, but has considered 
the advice of the consultant as only one of many factors among the other items discussed in this compensation discussion and 
analysis.  For a more detailed description of the CNG Committee and its responsibilities, see "Item 10. Directors and Executive 
Officers of the Managing General Partner and Corporate Governance" in this Annual Report on Form 10-K.

During 2015, at the direction of the Board, the CNG Committee retained Meridian Compensation Partners ("Meridian") to 
advise on a new long-term incentive strategy to be implemented in 2016 in order to incentivize and retain management in light of 
the significant decrease in phantom unit award value and GP Bonus Awards.  See "—Evaluation of 2016 Performance; Components 
of Compensation-Long-Term Incentive Compensation-2016 Cash Long-Term Incentive Plan" below.  In selecting Meridian as its 
compensation consultant, the CNG Committee assessed the independence of Meridian pursuant to SEC rules and considered, 
among other things, whether Meridian provides any other services to NRP, the policies of Meridian that are designed to prevent 
any conflict of interest between Meridian, the CNG Committee and NRP, any personal or business relationship between Meridian 
and a member of the CNG Committee or one of NRP’s executive officers and whether Meridian owned any of NRP’s common 
units.  In addition to the foregoing, the CNG Committee received documentation from Meridian addressing the firm’s independence.  
Meridian was engaged directly by the CNG Committee, reported exclusively to the CNG Committee and does not provide any 
additional services to NRP.  The CNG Committee concluded that Meridian is independent and did not have any conflicts of interest.  
While  management  did  cooperate  with  Meridian  in  collecting  data  with  respect  to  NRP’s  compensation  programs,  the  CNG 
Committee determined that management had not attempted to influence Meridian’s review or recommendations.

Role of Our Executive Officers in the Compensation Process

Mr. Hogan,  our  President  and  Chief  Operating  Officer,  provided  Mr.  Robertson  with  recommendations  relating  to  the 
executive  officers  other  than  himself  in  connection  with  the  evaluation  of  the  2016  compensation  programs.  Mr. Robertson 
considered those recommendations and provided the CNG Committee with recommendations for all of the executive officers other 
than himself.  Mr. Robertson relied on his personal experience in setting compensation over a number of years in determining the 
appropriate amounts for each employee, and considered each of the factors described elsewhere in this compensation discussion 
and  analysis.  Mr. Robertson  and  Mr. Hogan  attended  the  CNG  Committee  meetings  at  which  the  Committee  deliberated  and 
approved the compensation, but were excused from the meetings when the CNG Committee discussed their compensation. Mr. 
Nunez and Ms. Wilson also participated in the meetings with Meridian and the CNG Committee with respect to the design and 
implementation of the 2016 Cash Long-Term Incentive Plan.

124

Evaluation of 2016 Performance; Components of Compensation

2016 Performance

Our Board of Directors considers Adjusted EBITDA, distributable cash flow and overall leverage to be the critical measures 
in evaluating NRP’s performance.  Despite the continued depressed coal and oil and gas markets in 2016, we recorded Adjusted 
EBITDA in 2016 of $255.5 million, which was essentially flat compared to our Adjusted EBITDA in 2015, and distributable cash 
flow of $271.4 million, which increased from $176.6 million in 2015 primarily as a result of cash proceeds from asset sales in 
2016.

Other factors considered by the CNG Committee in determining total management compensation for 2016 included:

• 

• 

• 

• 

• 

• 

the sale of approximately $181 million of assets during 2016, including $116.1 million of oil and gas working 
interests and royalty interests that marked NRP’s strategic exit from the non-operated oil and gas working interest 
business;

the permanent reduction in NRP’s debt of approximately $248 million during 2016; 

the extension in 2016 of the maturity date under Opco’s revolving credit facility to June 2018; 

the increase in the trading price of NRP’s common units of over 300% during 2016; 

overall cost reductions; and

additional revenue of $40 million recognized in connection with lease amendments in the coal segment.

Base Salaries

With the exception of Mr. Robertson, who, as described above, does not receive a salary for his services as Chief Executive 
Officer, our executive officers are paid an annual base salary by Quintana Minerals Corporation ("Quintana") or Western Pocahontas 
Properties Limited Partnership ("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 2016, at the December 2015 meeting, the CNG Committee considered 
the financial performance of NRP for the nine months ended September 30, 2015 as well as the projected financial performance 
of NRP for the fourth quarter of 2015 and for the year ending December 31, 2016.  The CNG Committee also considered the 
individual performance of each member of the executive management team during 2015 and the changes to the management team 
that became effective during the year. Based on its review, the CNG Committee approved the salaries disclosed in the Summary 
Compensation Table below.

Annual Cash Incentive Awards

Each named executive officer participated in two cash incentive programs in 2016, with the exception of Mr. Robertson who 
did not participate in the cash bonus program. The first program is a discretionary cash bonus award approved in February 2017 
by the CNG Committee based on similar criteria used to evaluate the annual base salaries. The bonuses awarded with respect to 
2016 under this program are disclosed in the Summary Compensation Table under the Bonus column. As with the base salaries, 
there are no formulas or specific performance targets related to these awards. The bonuses for Mr. Hogan, Mr. Nunez, Ms. Wilson 
and Mr. Zolas were increased over the prior year in part to offset the declines in other components of their compensation and in 
recognition of their contributions to NRP.

Under  the  second  cash  incentive  program  (the  GP  Bonus Award  program),  our  general  partner  has  set  aside  the  cash 
distributions it receives on an annual basis with respect to distributions on NRP’s common units held by our general partner for 
awards to our executive officers, including Mr. Robertson.  Although Mr. Robertson has the sole discretion to determine the GP 
Bonus Awards allocated to each executive officer, including himself, the cash awards that our officers receive under this plan are 

125

reviewed by the CNG Committee and taken into account when making determinations with respect to salaries, bonuses and long-
term incentive awards. Unlike the discretionary cash bonus award described above, the GP Bonus Awards are paid by the general 
partner and not reimbursed by NRP.  However, because the GP Bonus Awards represent compensation to executive officers related 
to services provided to NRP, they are recorded by NRP as general and administrative expenses and equity contributions from the 
general partner.  Prior to 2015, we did not record the GP Bonus Awards cash compensation paid by the general partner as an 
expense.

The amounts received by the named executive officers under the GP Bonus Award program were significantly lower for 
2016 as compared to 2015 due to the 87% reduction in the per unit distribution paid by NRP during the calendar year ended 
December 31, 2015.  This decrease resulted in a decreased overall amount allocated to the executive officers.  Mr. Robertson 
determined to allocate the GP Bonus Awards equally among our executive officers.

Long-Term Incentive Compensation

At the time of our initial public offering, we adopted the Natural Resource Partners Long-Term Incentive Plan for our directors 
and all the employees who perform services for NRP, including the executive officers.  Historically, we considered long-term 
equity-based incentive compensation to be the most important element of our compensation program for executive officers because 
we believed that these awards kept our officers focused on the growth of NRP, particularly the sustainability and long-term growth 
of quarterly distributions and their impact on our unit price, over an extended time horizon.  

Our CNG Committee has historically approved annual awards of phantom units that vest four years from the date of grant. 
The amounts included in the compensation table reflect the grant date fair value of the unit awards determined in accordance with 
FASB stock compensation authoritative guidance. NRP bears 100% of the costs of the phantom units. We structured the phantom 
unit awards so that our executive officers and directors directly benefited along with our unitholders when our unit price increases, 
and experienced reductions in the value of their incentive awards when our unit price declined. Similarly, because the awards are 
forfeited by the executives upon termination of employment in most instances, the long-term vesting component of these awards 
encouraged our senior executives and employees to remain with NRP over an extended period of time, thereby ensuring continuity 
in our management team.  Consistent with this approach, we included DERs as a possible award to be granted under the plan. The 
DERs are contingent rights, granted in tandem with phantom units, to receive upon vesting of the related phantom units an amount 
in cash equal to the cash distributions made by NRP with respect to the common units during the period in which the phantom 
units are outstanding.

As noted below, in light of then existing market conditions, the relative low value of NRP’s common units and the strategic 
plan to dedicate all free cash flow towards reducing NRP’s leverage, the CNG Committee determined that the phantom units and 
DERs awarded under the Long-Term Incentive Plan no longer held retentive value for NRP’s management team.  As a result, the 
CNG Committee recommended, and the Board approved, the 2016 Cash Long-Term Incentive Plan described below.

2016 Cash Long-Term Incentive Plan

In February 2016, the CNG Committee adopted a new cash-based long-term incentive plan and recommended the new plan 
and awards thereunder to the non-management members of the Board for approval.  The Board approved the new plan and the 
forms of long-term incentive award agreements in February 2016.  Two types of cash incentive awards were made to the executive 
officers in March 2016: (1) time vesting awards, 50% of which vested in February 2017 and 50% of which will vest in February 
2018, and (2) performance-based awards that provide that such awards vest 50% upon the repayment, refinancing or rollover of 
the Opco revolving credit facility that matures in April 2018 and 50% upon the repayment, refinancing or rollover of NRP’s 9.125% 
Senior Notes due October 2018, in each case as determined by the Board and depending upon the continued employment of the 
applicable executive officer. The performance awards also provide that up to an additional 100% of the amount of the performance-
based awards may be awarded to the executive officers in the sole discretion of the Board after considering additional performance 
criteria including, but not limited to, NRP’s common unit price, projected EBITDA, and leverage ratio.  The awards made in March 
2016 to the named executive officers under the cash long-term incentive plan are as follows:

(1)  One-half of each time vesting award granted in 2016 vested in 2017.

Following the completion of the March 2017 recapitalization transactions, on March 3, 2017, the Board determined that 
both vesting conditions of the performance awards had been met and therefore the target performance award grant amounts would 
be awarded to each executive officer. In addition, following consideration of additional performance criteria including, but not 
limited to: (1) the performance of NRP’s common units over the past twelve months and subsequent to the announcement of the 
transactions; (2) the 2016 and projected 2017 EBITDA for NRP; and (3) the current and projected leverage ratios for NRP and its 
subsidiaries, the Board determined to award an additional 100% of the amount of the performance-based awards to the executive 
officers. The amounts that will be paid to the named executive officers will be equal to 200% of the performance award grant 
amounts shown in the table above. These amounts will be paid will be paid to the officers within 30 days of the date of the Board’s 
determination.

Perquisites and Other Personal Benefits

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

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

Unit Ownership Requirements

We do not have any policy guidelines that require specified ownership of our common units by our directors or executive 
officers or unit retention guidelines applicable to equity-based awards granted to directors or executive officers. As of December 31, 
2016, our named executive officers held 21,540 phantom units that have been granted as compensation. In addition, Mr. Robertson 
directly or indirectly owns in excess of 20% of the outstanding units of NRP.

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.

Tax Implications of Executive Compensation

127

Because we are a partnership, Section 162(m) of the Internal Revenue Code does not apply to compensation paid to our 
named executive officers and accordingly, the CNG Committee did not consider its impact in determining compensation levels in 
2014, 2015 or 2016.  The CNG Committee has taken into account the tax implications to the partnership in its decision to limit 
the long-term incentive compensation to phantom units as opposed to options or restricted units.  

Accounting Implications of Executive Compensation

The CNG Committee has considered the partnership accounting implications, particularly the "book-up" cost, of issuing 
equity as incentive compensation, and has determined that phantom units offer the best accounting treatment for the partnership 
while still motivating and retaining our executive officers.

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, 2016.

detailed above.  One-half or each time vesting award granted in 2016 vested in February 2017.

None of our executive officers has an employment agreement, and the salary, bonus and phantom unit awards noted above 
are approved by the CNG Committee. See our disclosure under "—Compensation Discussion and Analysis" for a description of 
the factors that the CNG Committee considers in determining the amount of each component of compensation.

Subject to the rules of the exchange upon which the common units are listed at the time, the Board and the CNG Committee 
have the right to alter or amend the Long-Term Incentive Plan or any part of the Long-Term Incentive Plan from time to time. 
Except upon the occurrence of unusual or nonrecurring events, no change in any outstanding grant may be made that would 
materially reduce any award to a participant without the consent of the participant.

The CNG Committee may make grants under our long-term incentive plans to employees and directors containing such 
terms as it determines, including the vesting period. Outstanding grants vest upon a change in control of NRP, our general partner 
or GP Natural Resource Partners LLC. If a grantee’s employment or membership on the Board terminates for any reason, outstanding 
grants will be automatically forfeited unless and to the extent the CNG Committee provides otherwise.

130

As stated above under "—Compensation Discussion and Analysis," we have no outstanding option grants, and do not intend 
to grant any options or restricted unit awards in the future.  In addition, the CNG Committee determined to make cash long-term 
incentive awards in 2016 in lieu of phantom unit awards as described above under "—Compensation Discussion and Analysis—
2016 Cash Long-Term Incentive Plan."  The CNG Committee may determine to make additional awards of phantom units in the 
future.

Potential Payments upon Termination or Change in Control

None of our executive officers have entered into employment agreements with Natural Resource Partners or its affiliates. 
Consequently, there are no severance benefits payable to any executive officer upon the termination of their employment. Upon 
the occurrence of a change in control of NRP, our general partner or GP Natural Resource Partners LLC, the outstanding phantom 
unit awards held by each of our executive officers would immediately vest. The table below indicates the impact of a change in 
control on (1) the outstanding cash awards under the 2016 Cash Long-Term Incentive Plan and (2) the outstanding equity-based 
awards at December 31, 2016, based on a unit price of $34.65, the 20-day average common unit price as of December 31, 2016, 
as required pursuant to the term of the phantom units.

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 and is the Chairman and Chief Executive Officer of New 
Gauley Coal Corporation.

Omnibus Agreement

Non-competition Provisions

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.

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 

135

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

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

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

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

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

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

Board Representation and Observation Rights Agreement

Effective on March 2, 2017 in connection with the closing of the issuance of the Preferred Units, pursuant to the Board 
Representation and Observation Rights Agreement, Blackstone appointed Jasvinder S. Khaira to serve on the Board of Directors 
of GP Natural Resource Partners LLC and also appointed one observer to attend meetings of the Board. Blackstone's rights to 
appoint a member of the Board and an observer will terminate at such time as Blackstone, together with their affiliates, no longer 
own the Minimum Preferred Unit Threshold (as defined elsewhere in this Annual Report on Form 10-K). 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. The 
Board Representation and Observation Rights Agreement is filed as Exhibit 4.29 to this Annual Report on Form 10-K and herein 
incorporated by reference.

Restricted Business Contribution Agreement

In connection with our partnership with Christopher Cline and his affiliates, Mr. Cline, Foresight Reserves LP and Adena 
(collectively, the "Cline Parties") and NRP have executed a Restricted Business Contribution Agreement. Pursuant to the terms of 
the Restricted Business Contribution Agreement, the Cline Parties and their affiliates are obligated to offer to NRP any business 
owned, operated or invested in by the Cline Parties, subject to certain exceptions, that either (a) owns, leases or invests in hard 
minerals or (b) owns, operates, leases or invests in transportation infrastructure relating to future mine developments by the Cline 
Parties in Illinois. In addition, we created an area of mutual interest (the "AMI") around certain of the properties that we have 
acquired from Cline affiliates. During the applicable term of the Restricted Business Contribution Agreement, the Cline Parties 
will be obligated to contribute any coal reserves held or acquired by the Cline Parties or their affiliates within the AMI to us. In 
connection with the offer of mineral properties by the Cline Parties to NRP, the parties to the Restricted Business Contribution 
Agreement will negotiate and agree upon an area of mutual interest around such minerals, which will supplement and become a 
part of the AMI.

We have made several acquisitions from Cline affiliates pursuant to the Restricted Business Contribution Agreement. 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 13. Related Party Transactions—Cline Affiliates" elsewhere in this Annual 
Report on Form 10-K.

Mr. Holcomb, who was appointed to the Board in October 2013 and resigned from the Board in April 2016, previously 
served as Chief Financial Officer for Foresight Reserves LP and its subsidiaries. Mr. Holcomb owned a less than 1% equity interest 
in certain Cline affiliates until March 2013 when he fully divested from all Cline affiliates. As a result of his position as an executive 
officer and an equity holder of certain Cline affiliates, Mr. Holcomb may be deemed to have had an indirect material interest in 
the transactions with the Cline affiliates described in this Annual Report on Form 10-K.

Mr. Holcomb is a manager of Cline Trust Company, LLC, which owns common units and 2018 Notes. The members of the 
Cline Trust Company are four trusts for the benefit of the children of Christopher Cline, each of which owns an approximately 
equal membership interest in the Cline Trust Company. Mr. Holcomb also serves as trustee of each of the four trusts.

Investor Rights Agreement

NRP and certain affiliates and Adena executed an Investor Rights Agreement pursuant to which Adena was granted certain 
management rights. Specifically, Adena has the right to name two directors (one of which must be independent) to the Board of 
Directors of our managing general partner so long as Adena beneficially owns either 5% of our limited partnership interest or 5% 
of  our  general  partner’s  limited  partnership  interest  and  so  long  as  certain  rights  under  our  managing  general  partner’s  LLC 
Agreement have not been exercised by Adena or Mr. Robertson. Leo A. Vecellio and L.G. (Trey) Jackson III currently serve as 
Adena’s two directors. Mr. Vecellio serves on our CNG Committee. Adena will also have the right, pursuant to the terms of the 
Investor Rights Agreement, to withhold its consent to the sale or other disposition of any entity or assets contributed by Cline 
affiliates to NRP, and any such sale or disposition will be void without Adena’s consent.

Quintana Capital Group GP, Ltd.

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

NRP’s business strategy has historically focused on:

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

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

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

137

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

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

•  The operation of construction aggregates mining and production businesses.

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

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

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

• 

• 

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

Investments outside of North America.

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

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

In addition, although NRP’s current oil and gas strategy is focused on the acquisition of minerals, royalties and non-operated 
working interests, NRP may also consider the acquisition of operated interests. 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, is Chairman of the Board 
of Corsa.

For more information on our relationship with Corsa Coal, see "Item 8. Financial Statements and Supplemetary Data—Note 

13. Related Party Transactions—Quintana Capital Group GP, Ltd."

Office Building in Huntington, West Virginia

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

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

Conflicts of Interest

Conflicts of interest exist and may arise in the future as a result of the relationships between our general partner and its 
affiliates (including the WPP Group, the Cline entities, and their affiliates) 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.

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

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

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

such matters as:

• 

• 

• 

amount and timing of asset purchases and sales;

cash expenditures;

borrowings;

139

• 

• 

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.

Excluding VantaCore, we do not have any officers or employees and rely solely on officers and employees of GP Natural 
Resource Partners LLC and its affiliates.

Excluding our VantaCore business, we do not have any officers or employees and rely solely 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. 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.

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.

140

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, the Omnibus Agreement and 
the Restricted Business Contribution Agreement, affiliates of our general partner will not be prohibited from engaging in activities 
in which they compete directly with us.

As a result of the purchase of the Preferred Units, 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 and our general partner on the 
one hand, and Blackstone or GoldenTree on the other hand.  

The Conflicts Committee Charter is available upon request.

Director Independence

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

Review, Approval or Ratification of Transactions with Related Persons

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

Pursuant to our Code of Business Conduct and Ethics, conflicts of interest are prohibited as a matter of policy, except under 
guidelines approved by the Board and as provided in the Omnibus Agreement, the Restricted Business Contribution Agreement, 
and our partnership agreement. For the year ended December 31, 2016, there were no transactions where such guidelines were 
not followed.

ITEM 14.  PRINCIPAL ACCOUNTANT FEES AND SERVICES

The Audit Committee of the Board of Directors of GP Natural Resource Partners LLC recommended and we engaged Ernst & 
Young LLP to audit our accounts and assist with tax work for fiscal 2016 and 2015. All of our audit, audit-related fees and tax 
services have been approved by the Audit Committee of our Board of Directors. The following table presents fees for professional

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.

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.

142

II. Delegation

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

III. Audit Services

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

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

IV. Audit-related Services

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

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.

143

VII. Procedures

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

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

MINE SAFETY DISCLOSURE

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

Section 1503 of the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”) requires 
issuers to include in periodic reports filed with the Securities and Exchange Commission (“SEC”) certain information relating to 
citations and orders for violations of standards under the Mine Act.  The following tables disclose information required under the 
Dodd-Frank Act for the 12-month period ending December 31st, 2016.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Managers and Members of

Ciner Wyoming LLC

Atlanta, Georgia

We have audited the accompanying balance sheets of Ciner Wyoming LLC (the “Company”) as of December 31, 2016 and 2015, 
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, 2016. These financial statements are the responsibility of the Company’s management. Our 
responsibility is to express an opinion on these financial statements based on our audits. 

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States) 
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. 
The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. 
Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are 
appropriate in the circumstances, 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. An audit also includes examining, on a test basis, 
evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant 
estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits 
provide a reasonable basis for our opinion.

In our opinion, such financial statements referred to above present fairly, in all material respects, the financial position of the 
Company as of December 31, 2016 and 2015, and the results of its operations and its cash flows for each of the three years in the 
period ended December 31, 2016, in conformity with accounting principles generally accepted in the United States of America.

(Dollars in thousands)

1.  Corporate Structure

A 51% membership interest in Ciner Wyoming LLC (the "Company," "we," "us," or "our") is owned by Ciner Resources 
LP (CINR or the "Partnership"). NRP Trona LLC, a wholly owned subsidiary of Natural Resource Partners LP (NRP) owns 
a 49% membership interest in the Company.  CINR is a master limited partnership traded on the New York Stock exchange 
and is currently owned approximately 75% by Ciner Wyoming Holding Co. (CINWHCO) and approximately 25% by the 
general public. CINWHCO is 100% owned by Ciner Resources Corporation (CRC) which is ultimately 100% owned by 
Ciner Enterprises, Inc. (CINE). CINE is 100% owned by Akkan Enerji ve Madencilik Anonim 
("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. 

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

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

2. Nature of Operations and Summary of Significant Accounting Policies

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

A summary of the significant accounting policies is as follows:

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

Use of Estimates - The preparation of financial statements, in accordance with accounting principles generally accepted in 
the United States of America, requires management to make estimates and assumptions that affect the reported amounts of 
assets and liabilities, and disclosure of contingent assets and liabilities at the dates of the financial statements, and the reported 
amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

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

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

9

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. If actual collection experience changes, revisions to the allowance may 
be required. Accounts receivable are written off when deemed uncollectible. Recoveries of accounts receivable previously 
written off are recorded when received. During the years ended 2016, 2015 and 2014 there were no significant accounts 
receivable bad debt expenses, write-offs or recoveries.

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

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

•  Finished goods inventory is the finished product soda ash.

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

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

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

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

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

Derivative Instruments and Hedging Activities - The Company may enter into derivative contracts from time to time to 
manage exposure to the risk of exchange rate changes on its foreign currency transactions, the risk of changes in natural gas 
prices, and the risk of the variability in interest rates on borrowings. Gains and losses on derivative contracts are reported 
as  a  component  of  the  underlying  transactions.  The  Company  follows  hedge  accounting  for  its  hedging  activities. All 
derivative instruments are recorded on the balance sheet at their fair values. The accounting for changes in the fair value of 
a  derivative  depends  on  the  intended  use  of  the  derivative  and  the  resulting  designation.  The  Company  designates  its 
derivatives  based  upon  criteria  established  for  hedge  accounting  under  generally  accepted  accounting  principles.  For  a 
derivative designated as a fair value hedge, the gain or loss is recognized in earnings in the period of change together with 
the offsetting gain or loss on the hedged item attributed to the risk being hedged. For a derivative designated as a cash flow 

10

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 entered into interest rate swap contracts, designed as cash flow hedges, to mitigate the exposure to possible 
increases in interest rates. These contracts are for periods consistent with the exposure being hedged and will mature on July 
18, 2018, the maturity date of the long-term debt under the Ciner Wyoming Credit Facility. These contracts had an aggregate 
notional value of $72,000 and $74,000 at December 31, 2016 and December 31, 2015, respectively. At December 31, 2016, 
it was anticipated that approximately $400 of losses currently recorded in accumulated other comprehensive income (loss) 
will be reclassified into earnings within the next 12 months.

The Company has entered into natural gas forward contracts, designed as cash flow hedges, to mitigate volatility in the price 
of the natural gas the Company consumes. These contracts generally have various maturities through 2021. These contracts 
had an aggregate notional value of  $30,969 and $15,831 at December 31, 2016 and December 31, 2015, respectively.  At 
December 31, 2016, it was anticipated that $601 of gains currently recorded in accumulated other comprehensive income 
(loss) will be reclassified into earnings within the next 12 months.

The Company entered into foreign exchange forward contracts to hedge certain firm commitments denominated in currencies 
other than the U.S. dollar. However, the Company did not apply hedge accounting for these contracts at December 31, 2015. 
These contracts were for periods consistent with the exposure being hedged and generally had maturities of one year or less. 
These contracts, which were predominantly used to purchase U.S. dollars and sell Euros, had an aggregate notional value 
of $4,160 at December 31, 2015. The Company had no similar contracts outstanding as of December 31, 2016.

Income Tax - The Company is organized as a pass-through entity for federal income tax purposes. 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.

11

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

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

The estimated original liability calculated in 1996 for the refinery and tailing ponds was calculated based on the estimated 
useful life of the mine, which was 80 years, and on external and internal estimates as to the cost to restore the land in the 
future and state regulatory requirements. In 2017, the mining reserve will be amortized over a remaining life of 66 years. 
During 2016, 2015 and 2014 the remaining life was 67 years, 68 years and 66 years, respectively. The liability was discounted 
using a weighted average credit-adjusted risk free rate of approximately 6% and is being accreted throughout the estimated 
life of the related assets to equal the total estimated costs with a corresponding charge being recorded to cost of products 
sold.

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

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

Financial instruments consist primarily of cash and cash equivalents, accounts receivable, accounts payable, accrued expenses 
and long-term debt. The carrying amounts of cash and cash equivalents, accounts receivable, accounts payable and accrued 
expenses approximate their fair value because of the nature of such instruments. Our long-term debt and derivative financial 
instruments are measured at their fair values with Level 2 inputs based on quoted market values for similar but not identical 
financial instruments.

Long-Term Debt - The fair value of our long-term debt is based on present rates for 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.

12

Subsequent  Events -  The  Company  has  evaluated  all  subsequent  events  through  March 6,  2017,  the  date  the  financial 
statements were available to be issued.

Recently Issued Accounting Standards - In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting 
Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (Topic 606) that requires companies to 
recognize revenue when a customer obtains control rather than when companies have transferred substantially all risks and 
rewards of a good or service. The Company should apply the guidance in ASU 2014-09 to annual reporting periods beginning 
after December 15, 2017, including interim reporting periods within that reporting period.   The Company has completed 
its initial evaluation of the provisions of this ASU and does not expect our adoption of ASU 2014-09 to materially change 
the amount or timing of revenues recognized by us, nor expect it to materially affect our financial position. The majority of 
our revenues generated are recognized upon delivery and transfer of title to the product to our customers. The time at which 
delivery and transfer of title occurs, for majority of our contracts with customers, is the point when the product leaves our 
facility, thereby rendering our performance obligation fulfilled. The FASB issued various amendments to ASU 2014-09, one 
of which includes allowing entities to elect to account for shipping and handling activities performed after the control of a 
good has been transferred to the customer as a fulfillment cost versus an obligation of a promised service. The Company 
expects to make this an accounting policy election upon adoption.  We currently include freight costs billed to customers 
for shipments administered by us in gross sales.  We will adopt this ASU effective January 1, 2018, and tentatively expect 
to apply the modified retrospective (cumulative effect) method of adoption as permitted by the ASU. During 2017, we will 
develop our revenue disclosures and enhance our accounting systems, if applicable.

In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and 
Measurement  of  Financial  Assets  and  Financial  Liabilities  (ASU  2016-01).  The  standard  amends  certain  aspects  of 
recognition, measurement, presentation, and disclosure of financial assets and liabilities. ASU 2016-01 is effective for fiscal 
years, and interim periods within those years, beginning after December 15, 2017. The Company is currently evaluating the 
potential impact the adoption of ASU 2016-01 will have on its financial statements, as well as, available transition methods.

In  February  2016,  the  FASB  issued ASU  No.  2016-02,  Leases  (Topic  842). The  update  amends  existing  standards  for 
accounting for leases by lessees, with accounting for leases by lessors remaining largely unchanged from current guidance. 
The update requires that lessees recognize a lease liability and a right of use asset for all leases (with the exception of short-
term leases) at the commencement date of the lease and disclose key information about leasing arrangements. The update 
is  effective  for  interim  and  annual  periods  beginning  after  December  15,  2018  and  must  be  adopted  using  a  modified 
retrospective transition. The ASU No. 2016-02 provides for certain practical expedients and early adoption is permitted. The 
Company is evaluating the potential impact the adoption of ASU No. 2016-02 will have on its financial statements; however, 
based on our current operating leases, it is not expected to have a material impact.

The Variable Rate Demand Revenue Bonds are held by CINWYLLC.  These revenue bonds require the Company to maintain 
standby letters of credit totaling $20,333 at December 31, 2016. These letters of credit require compliance with certain 
covenants, including minimum net worth, maximum debt to net worth, and interest coverage ratios. As of December 31, 
2016, the Company was in compliance with these debt covenants. 

Ciner Wyoming Credit Facility

On July 18, 2013, the Company entered into a $190,000 senior unsecured revolving credit facility, as amended on October 
30, 2014 (as amended, the "Ciner Wyoming Credit Facility"), with a syndicate of lenders, which will mature on the fifth 
anniversary of the closing date of such credit facility. The Ciner Wyoming Credit Facility provides for revolving loans to 

15

fund  working  capital  requirements,  capital  expenditures,  to  consummate  permitted  acquisitions  and  for  all  other  lawful 
Company purposes. The Ciner Wyoming Credit Facility has an accordion feature that allows Ciner Wyoming to increase 
the available revolving borrowings under the facility by up to an additional $75,000, subject to the Company receiving 
increased commitments from existing lenders or new commitments from new lenders and the satisfaction of certain other 
conditions. In addition, the Ciner Wyoming Credit Facility includes a sublimit up to $20,000 for same-day swing line advances 
and a sublimit up to $40,000 for letters of credit. The Company's obligations under the Ciner Wyoming Credit Facility are 
unsecured.

On May 25, 2016, Ciner Wyoming entered into a Second Amendment to the Credit Agreement, First Amendment to Notes 
and  First Amendment  to  Fee  Letter  (the  “Ciner Wyoming  Second Amendment”)  with  each  of  the  lenders  listed  on  the 
respective signature pages thereof and Bank of America, N.A., as administrative agent, swing line lender and L/C issuer. 
The Ciner Wyoming Second Amendment amends the Ciner Wyoming Credit Facility.

Among other things, the Ciner Wyoming Second Amendment (i) amends the Ciner Wyoming Credit Facility by modifying 
the consolidated fixed charge coverage ratio (the ratio of consolidated cash flow to consolidated fixed charges, each as 
defined in the Ciner Wyoming Credit Facility) from not less than 1.15 to 1.00, prior to the Ciner Wyoming Second Amendment, 
to be not less than 1.00 to 1.00 as of the end of any fiscal quarter and (ii) prohibits financial institutions from European 
Economic Area member countries from serving as loan parties under the Ciner Wyoming Credit Facility.

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

•  make distributions on or redeem or repurchase units;

• 

incur or guarantee additional debt;

•  make certain investments and acquisitions;

• 

incur certain liens or permit them to exist;

•  enter into certain types of transactions with affiliates of the Company;

•  merge or consolidate with another Company; and

• 

transfer, sell or otherwise dispose of assets.

The Ciner Wyoming Credit Facility also requires quarterly maintenance of a leverage ratio (as defined in the Ciner Wyoming 
Credit Facility) of not more than 3.00 to 1.00 and a fixed charge coverage ratio (as defined in the Ciner Wyoming Credit 
Facility) of not less than 1.00 to 1.00.  The Ciner Wyoming Credit Facility also requires that capital expenditures, as defined 
in the Ciner Wyoming Credit Facility, not exceed $50,000 in any fiscal year.

  In addition, the Ciner Wyoming Credit Facility contains events of default customary for transactions of this nature, including 
(i) failure to make payments required under the Ciner Wyoming Credit Facility, (ii) events of default resulting from failure 
to comply with covenants and financial ratios in the Ciner Wyoming Credit Facility, (iii) the occurrence of a change of 
control, (iv) the institution of insolvency or similar proceedings against Ciner Wyoming and (v) the occurrence of a default 
under any other material indebtedness Ciner Wyoming may have. Upon the occurrence and during the continuation of an 
event of default, subject to the terms and conditions of the Ciner Wyoming Credit Facility, the lenders may terminate all 
outstanding commitments under the Ciner Wyoming Credit Facility and may declare any outstanding principal of the Ciner 
Wyoming Credit Facility debt, together with accrued and unpaid interest, to be immediately due and payable.

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

16

The Company was in compliance with all terms under its long-term debt agreements as of December 31, 2016.

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

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

•  a LIBOR Rate plus an applicable margin.

The unused portion of the Ciner Wyoming Credit Facility is subject to an unused line fee ranging from 0.275% to 0.350% 
per annum based on the Company's then current consolidated leverage ratio.

Ciner Enterprises Credit Agreement

In addition, there are restrictions in the Ciner Enterprises Credit Agreement that affect the Company. Specifically, Ciner 
Enterprises has agreed (subject to certain exceptions in addition to those described below) that it will not, and will not permit 
any of its subsidiaries, including the Company to:

•  make  distributions  on  or  redeem  or  repurchase  equity  interests,  other  than  distributions  to  the  Companies 
members;

incur or guarantee additional debt, other than debt incurred under the Ciner Wyoming Credit Facility, among 

• 
certain other types of permitted debt;

•  make certain investments and acquisitions, other than investments in the Company, in an amount not to exceed 
$10,000 per calendar year and other exceptions set forth therein;

incur certain liens or permit them to exist, other than, with respect to the Companies liens, an aggregate amount 

• 
outstanding at any time equal to $1,000;

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

•  merge or consolidate with another company; or

transfer, sell or otherwise dispose of assets, other than the Companies disposition of assets with a net book value 

• 
not to exceed $2,500, in any given year.

10. EMPLOYEE BENEFIT PLANS

The Company participates in various benefit plans offered and administered by CRC (administered by OCIE prior to the 
Transaction) and is allocated its portions of the annual costs related thereto. The specific plans are as follows:

Retirement Plans - Benefits provided under the Ciner Pension Plan for Salaried Employees and Ciner Pension Plan for 
Hourly Employees are based upon years of service and average compensation for the highest 60 consecutive months of the 
employee's last 120 months of service, as defined. Each plan covers substantially all full-time employees hired before May 1, 
2001. CRC's funding policy is to contribute an amount within the range of the minimum required and the maximum tax-
deductible contribution. The Company's allocated portion of net periodic pension cost was $2,015, $7,731 and $3,140 for 
the years ended December 31, 2016, 2015 and 2014, respectively. The decrease in pension costs in 2016 was driven by lower 
overall pension cost at the CRC level as a result of the retirement plans being fair valued in connection with Ciner Enterprises’ 
acquisition of CRC.

Savings Plan - The Ciner 401(k) Retirement Plan covers all eligible hourly and salaried employees. Eligibility is limited to 
all domestic residents and any foreign expatriates who are in the United States indefinitely.  The plan permits employees to 
contribute  specified  percentages  of  their  compensation,  while  the  Company  makes  contributions  based  upon  specified 
percentages of employee contributions. The Plan was amended such that participants hired on or subsequent to May 1, 2001, 
will receive an additional contribution from the Company based on a percentage of the participant’s base pay. Contributions 
made by the Company for the years ended December 31, 2016, 2015 and 2014 were $1,625, $2,582 and $2,428, respectively.

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

CRC accounts for postretirement benefits on an accrual basis over an employee’s period of service. The postretirement plan, 
excluding pensions, are not funded, and CRC has the right to modify or terminate the plan. Effective January 1, 2013, the 
postretirement benefits for non-grandfathered retirees were amended to
replace  the  medical  coverage  for  post-65-year-old  members  with  a  fixed  dollar  contribution  amount. As  a  result  of  the 
amendment, the accumulated and projected benefit obligation for CRC's postretirement benefits

12. COMMITMENTS AND CONTINGENCIES

The  Company  leases  mineral  rights  from  the  U.S.  Bureau  of  Land  Management,  the  state  of Wyoming,  Rock  Springs 
Royalty Corp., a wholly owned subsidiary of Anadarko Holding Company (AHC), and other private parties. All of these 
leases provide for royalties based upon production volume. The remaining leases provide for minimum lease payments as 
detailed in the table below. The Company has a perpetual right of first refusal with respect to these leases and intends to 
continue renewing the leases as has been its practice.

19

The  Company  entered  into  a  10 year  rail  yard  switching  and  maintenance  agreement  with  a  third  party,  Watco 
Companies, LLC, on December 1, 2011. Under the agreement, Watco provides rail-switching services at the Company’s rail 
yard. The Company's rail yard is constructed on land leased by Watco from Rock Springs Grazing Association and Anadarko 
Land Corp; the Rock Springs Grazing Association land lease is renewable every 5 years for a total period of 30 years, while 
the Anadarko Land Corp. lease is perpetual. The Company has an option agreement with Watco to assign these leases to the 
Company at any time during the land lease term.

The Company entered into two track lease agreements, collectively, not to exceed 10 years with Union Pacific Company 
for certain rail tracks used in connection with the rail yard.

As of December 31, 2016, the total minimum rental commitments under the Company’s various operating leases, including 
renewal periods are as follows:

CRC, on behalf of the Company, typically enters into operating lease contracts with various lessors for railcars to transport 
product to customer locations and warehouses. Railcar leases under these contractual commitments range for periods from 
1 to 10 years. CRC's obligations related to these railcar leases are $12,484 in 2017, $11,345 in 2018, $10,396 in 2019, $7,777 
in 2020, $5,215 in 2021 and $5,899 in 2022 and thereafter. Total lease expense was approximately $14,476, $12,415 and 
$9,469 for the years ended December 31, 2016, 2015 and 2014, respectively.  

Purchase Commitments - The Company has natural gas supply contracts to mitigate volatility in the price of natural gas. As 
of  December 31,  2016,  these  contracts  totaled  $77,063  for  the  purchase  of  a  portion  of  our  gas  requirements  over 
approximately the next five years. The supply purchase agreements have specific commitments of $24,292 in 2017, $20,126 
in 2018 $17,130 in 2019, $10,116 in 2019 and $5,399 in 2021. The Company has a separate contract that expires in 2021, 
for transportation of natural gas with an average annual cost of approximately $3,946 per year.

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

Off-Balance Sheet Arrangements - The Company has a self-bond agreement with the Wyoming Department of Environmental 
Quality under which it commits to pay directly for reclamation costs at our Wyoming Plant site. As of December 31, 2016 
and 2015, the amount of the bond was $38,200 and $33,875, respectively, which is the amount we would need to pay the 
State of Wyoming for reclamation costs if we cease mining operations currently. The amount of this self-bond is subject to 
change upon periodic re-evaluation by the Land Quality Division.

13. AFFILIATES TRANSACTIONS

CRC is the exclusive sales agent for the Company and through its membership in ANSAC, CRC is responsible for promoting 
and increasing the use and sale of soda ash and other refined or processed sodium products produced. All actual sales and 
marketing costs incurred by CRC are charged directly to the Company. Selling, general and administrative expenses also 
include amounts charged to the Company by CRC principally consisting of salaries, benefits, office supplies, professional 
fees, travel, rent and other costs of certain assets used by the Company. In November 2016, CRC, on behalf of the Company, 
entered into a soda ash sales agreement with CIDT, an affiliate of Ciner Group, that sells soda ash to markets not served by 
ANSAC.  The receivables associated with these sales are recorded in accounts receivable - other affiliate line item on the 
consolidated balance sheet. These transactions do not necessarily represent arm's length transactions and may not represent 
all costs if the Company operated on a standalone basis.

As a result of the closing of the Transaction discussed in Note 1 - "Corporate Structure," CINE owns indirectly and controls 
the Company, therefore, OCIE and subsidiaries, including OCI Alabama LLC, are no longer related parties of the Company 
as of the Transaction date.  The following table includes transactions with OCIE and subsidiaries prior to the Transaction 
date.

The total costs (recoveries) charged to the Company by affiliates for the years ended December 31, 2016, 2015 and 2014 
are as follows:

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, 2016, 2015 
and 2014 are as follows:
