Factors that could cause actual results to differ include those risks and
uncertainties discussed in Part I, Item 1A. "Risk Factors."



In September 2019, we entered into an asset purchase agreement and a coal supply
asset purchase agreement related to our Pennyrile mining operation ("Pennyrile")
with a third party. Please read below for additional details. Our consolidated
statements of operations have been retrospectively adjusted to reclassify our
Pennyrile operations to discontinued operations for the years ended December 31,
2019 and 2018.



Overview



Through a series of transactions completed in the first quarter of 2016, Royal
Energy Resources, Inc. ("Royal") acquired a majority ownership and control of us
and 100% ownership of our general partner.



We are a diversified coal producing limited partnership formed in Delaware that
is focused on coal and energy related assets and activities. We produce, process
and sell high quality coal of various steam and metallurgical grades. We market
our steam coal primarily to electric utility companies as fuel for their steam
powered generators. Customers for our metallurgical coal are primarily steel and
coke producers who use our coal to produce coke, which is used as a raw material
in the steel manufacturing process.



  61







We have a geographically diverse asset base with coal reserves located in
Central Appalachia, Northern Appalachia, the Illinois Basin and the Western
Bituminous region. As of December 31, 2019, we controlled an estimated 277.6
million tons of proven and probable coal reserves, consisting of an estimated
171.1 million tons of steam coal and an estimated 106.5 million tons of
metallurgical coal. In addition, as of December 31, 2019, we controlled an
estimated 190.7 million tons of non-reserve coal deposits. Periodically, we
retain outside experts to independently verify our coal reserve and our
non-reserve coal deposit estimates. The most recent audit by an independent
engineering firm of our coal reserve and non-reserve coal deposit estimates was
completed by Marshall Miller & Associates, Inc. as of December 31, 2019, and
covered a majority of the coal reserves and non-reserve coal deposits that we
controlled as of such date. We intend to continue to periodically retain outside
experts to assist management with the verification of our estimates of our coal
reserves and non-reserve coal deposits going forward.



We operate underground and surface mines located in Kentucky, Ohio, Virginia,
West Virginia and Utah. The number of mines that we operate will vary from time
to time depending on a number of factors, including the existing demand for and
price of coal, depletion of economically recoverable reserves and availability
of experienced labor.



Our principal business strategy is to safely, efficiently and profitably produce
and sell both steam and metallurgical coal from our diverse asset base in order
to resume, and, over time, increase our quarterly cash distributions. In
addition, we intend to continue to expand and potentially diversify our
operations through strategic acquisitions, including the acquisition of
long-term, cash generating natural resource assets. We believe that such assets
will allow us to grow our cash available for distribution and enhance stability
of our cash flow.



For the year ended December 31, 2019, we generated revenues from continuing
operations of approximately $181.0 million and a net loss from continuing
operations of approximately $47.6 million. For the year ended December 31, 2019,
we produced approximately 3.2 million tons of coal from continuing operations
and sold approximately 3.0 million tons of coal from continuing operations,
approximately 82.0% of which were pursuant to long-term supply contracts.



Current Liquidity and Outlook



As of December 31, 2019, our available liquidity was $0.1 million. We also have
a delayed draw term loan commitment in the amount of $25 million contingent upon
the satisfaction of certain conditions precedent specified in the financing
agreement discussed below.



On December 27, 2017, we entered into a financing agreement ("Financing
Agreement"), which provides us with a multi-draw loan in the original aggregate
principal amount of $80 million. The total principal amount is divided into a
$40 million commitment, the conditions for which were satisfied at the execution
of the Financing Agreement and a $40 million additional commitment that was
contingent upon the satisfaction of certain conditions precedent specified in
the Financing Agreement. As of December 31, 2019, we had utilized $15 million of
the $40 million additional commitment, which results in $25 million of the
additional commitment remaining. We used approximately $17.3 million of the
initial Financing Agreement net proceeds to repay all amounts outstanding and
terminate the amended and restated credit agreement with PNC Bank, National
Association, as Administrative Agent. The Financing Agreement initially had a
termination date of December 27, 2020, which was amended to December 27, 2022
per the fifth amendment to the Financing Agreement discussed further below. For
more information about our Financing Agreement, please read "- Liquidity and
Capital Resources-Financing Agreement."



Beginning in the later part of the third quarter of 2019, we have experienced
significantly weaker market demand and have seen prices move lower for the
qualities of met and steam coal we produce. This downward price trend has been
exacerbated by the recent coronavirus pandemic. In response to this reduced
demand and to the significant health threats to our employees, on March 20,
2020, we temporarily idled production at several of our mines. We will continue
to monitor conditions to ensure the health and welfare of our employees. We do
not expect the idling of the coal production activities will affect our ability
to fulfill current customer commitments, as loading and shipping crews will
remain in place to ship coal from existing inventories.



If we continue to experience weak demand and prices continue to lower for our
met and steam coal, we may not be able to continue to give the required
representations or meet all of the covenants and restrictions included in our
Financing Agreement. If we violate any of the covenants or restrictions in our
Financing Agreement, including the fixed-charge coverage ratio, some or all of
our indebtedness may become immediately due and payable, and our Lenders may not
be willing to make any loans under the additional commitment available under our
Financing Agreement. If we are unable to give a required representation or we
violate a covenant or restriction, then we will need a waiver from our Lenders
under our Financing Agreement, or they may declare an event of default and,
after applicable specified cure periods, all amounts outstanding under the
Financing Agreement would become immediately due and payable. Although we
believe our Lenders are well secured under the terms of our Financing Agreement,
there is no assurance that the Lenders would agree to any such waiver. Failure
to obtain financing or to generate sufficient cash flow from operations could
cause us to further curtail our operations and reduce spending and alter our
business plan. We are currently considering alternatives to address our
liquidity and balance sheet issues, such as selling additional assets or seeking
merger opportunities, and depending on the urgency of our liquidity constraints,
we may be required to pursue such an option at an inopportune time.



  62







As of December 31, 2019, we are unable to demonstrate that we have sufficient
liquidity to operate our business over the next twelve months from the date of
filing our Annual Report on Form 10-K and thus substantial doubt is raised about
our ability to continue as a going concern. Accordingly, our independent
registered public accounting firm has included an emphasis paragraph with
respect to our ability to continue as a going concern in its report on our
consolidated financial statements for the year ended December 31, 2019. The
presence of the going concern emphasis paragraph in our auditors' report may
have an adverse impact on our relationship with third parties with whom we do
business, including our customers, vendors, lenders and employees, making it
difficult to raise additional financing to the extent needed to conduct normal
operations. As a result, our business, results of operations, financial
condition and prospects could be materially adversely affected.



We continue to take measures, including the suspension of cash distributions on
our common and subordinated units and cost and productivity improvements, to
enhance and preserve our liquidity in order to fund our ongoing operations and
necessary capital expenditures and meet our financial commitments and debt

service obligations.



Recent Developments


Pennyrile Mine Complex ("Pennyrile") Asset Purchase Agreement





On September 6, 2019, we entered into an Asset Purchase Agreement (the
"Pennyrile APA") with Alliance Coal, LLC ("Buyer") and Alliance Resource
Partners, L.P. ("Buyer Parent") pursuant to which we agreed to sell to Buyer all
of the real property, permits, equipment and inventory and certain other assets
associated with Pennyrile in exchange for approximately $3.7 million, subject to
certain adjustments.



Pursuant to the Pennyrile APA, we retain liability for certain employee claims,
subsidence claims arising from pre-closing mining operations, MSHA liabilities
and certain other matters. The Pennyrile APA also provides that Buyer shall have
the right to conduct diligence on the Pennyrile mine complex and may contest the
fair market value of the purchased assets or the estimate of the costs of the
assumed liabilities following such diligence investigation. In the event Buyer
does contest such amounts, the parties will attempt to resolve the dispute and
to the extent they cannot, will submit the matter to a third party to make a
final determination with respect to such matters, and will adjust the purchase
price accordingly.



The parties have made customary representations, warranties and covenants in the
Pennyrile APA. The closing of the transactions contemplated by the Asset
Purchase Agreement are subject to a number of closing conditions, including,
among others, the performance of applicable covenants and accuracy of
representations and warranties and absence of material adverse changes in the
condition of Pennyrile. The transaction was completed in the first quarter

of
2020.


Coal Supply Asset Purchase Agreement


On September 6, 2019, we entered into an Asset Purchase Agreement with the Buyer
and Buyer Parent for the sale and assignment of certain coal supply agreements
associated with Pennyrile (the "Coal Supply APA") in exchange for approximately
$7.3 million. The Coal Supply APA includes customary representations of the
parties thereto and indemnification for losses arising from the breaches of such
representations and for liabilities arising during the period in which the
relevant parties were not party to the coal supply agreements. The transactions
contemplated by the Coal Supply APA closed upon the execution thereof.



Discontinued Operations



The Pennyrile operating results for the year ended December 31, 2019 and 2018
are recorded as discontinued operations, including a $38.7 million impairment
loss associated with the sale.



  63






Blackjewel Assignment Agreement





On August 14, 2019, our wholly owned subsidiary Jewell Valley Mining LLC,
entered into a general assignment and assumption agreement and bill of sale (the
"Assignment Agreement") with Blackjewel L.L.C., Blackjewel Holdings L.L.C.,
Revelation Energy Holdings, LLC, Revelation Management Corp., Revelation Energy,
LLC, Dominion Coal Corporation, Harold Keene Coal Co. LLC, Vansant Coal
Corporation, Lone Mountain Processing LLC, Powell Mountain Energy, LLC, and
Cumberland River Coal LLC (together, "Blackjewel") to purchase certain assets
from Blackjewel for cash consideration of $850,000 plus an additional royalty of
$250,000 that is payable within one year from the date of the purchase, as well
as the assumption of associated reclamation obligations. The assets that are
subject of the Assignment Agreement consist of three underground mines in
Virginia that were actively producing coal prior to Blackjewel's filing for
relief under Chapter 11 of the United States Bankruptcy Code, along with a
preparation plant, rail loadout facility, related mineral and surface rights and
infrastructure and certain purchase contracts to be assumed at our option. We
resumed mining operations at two of the mines in the fourth quarter of 2019.



Settlement Agreement



On June 28, 2019, we entered into a settlement agreement with a third party
which allows the third party to maintain certain pipelines pursuant to
designated permits at our Central Appalachia operations. The agreement required
the third party to pay us $7.0 million in consideration. We received $4.2
million on July 3, 2019 and the balance of $2.8 million was received on January
2, 2020. We recorded a gain of $6.9 million during the second quarter of 2019
related to this settlement agreement.



Financing Agreement



On February 13, 2019, we entered into a second amendment ("Amendment") to the
Financing Agreement. The Amendment provided the Lender's consent for us to pay a
one-time cash distribution on February 14, 2019 to the Series A Preferred
Unitholders not to exceed approximately $3.2 million. The Amendment allowed us
to sell our remaining shares of Mammoth Energy Services, Inc. (NASDAQ:
TUSK)("Mammoth Inc.") and utilize the proceeds for payment of the one-time cash
distribution to the Series A Preferred Unitholders and waived the requirement to
use such proceeds to prepay the outstanding principal amount outstanding under
the Financing Agreement. The Amendment also waived any Event of Default that has
or would otherwise arise under Section 9.01(c) of the Financing Agreement solely
by reason of us failing to comply with the Fixed Charge Coverage Ratio covenant
in Section 7.03(b) of the Financing Agreement for the fiscal quarter ending
December 31, 2018. The Amendment includes an amendment fee of approximately $0.6
million payable by us on May 13, 2019 and an exit fee equal to 1% of the
principal amount of the term loans made under the Financing Agreement that is
payable on the earliest of (w) the final maturity date of the Financing
Agreement, (x) the termination date of the Financing Agreement, (y) the
acceleration of the obligations under the Financing Agreement for any reason,
including, without limitation, acceleration in accordance with Section 9.01 of
the Financing Agreement, including as a result of the commencement of an
insolvency proceeding and (z) the date of any refinancing of the term loan under
the Financing Agreement. The Amendment amended the definition of the Make-Whole
Amount under the Financing Agreement to extend the date of the Make-Whole Amount
period to December 31, 2019.



On May 8, 2019, we entered into a third amendment ("Third Amendment") to the
Financing Agreement. The Third Amendment includes the Lenders' agreement to
waive any Event of Default that arose or would otherwise arise under the
Financing Agreement for failing to comply with the Fixed Charge Coverage Ratio
for the six months ended March 31, 2019. The Third Amendment increased the
original exit fee of 3.0% to 6.0%. The original exit fee of 3% was included in
the Financing Agreement at the execution date and the increase of the total exit
fee to 6% was included as part of the amendment dated February 13, 2019
discussed above and this Third Amendment. The exit fee is applied to the
principal amount of the loans made under the Financing Agreement that is payable
on the earliest of (a) the final maturity date, (b) the termination date of the
Financing agreement for any reason, (c) the acceleration of the obligations in
the Financing Agreement for any reason and (d) the date of any refinancing of
the term loan under the Financing Agreement.



  64







On August 16, 2019, we entered into a fourth amendment (the "Fourth Amendment")
to the Financing Agreement originally executed on December 27, 2017 with the
Lenders. The Fourth Amendment provided a $5.0 million term loan provided by the
Lenders to us under the delayed draw feature of the Financing Agreement, and
extended the period by which an applicable premium payable to the Lenders will
be calculated to the final maturity date.



On September 6, 2019, we entered into a fifth amendment (the "Fifth Amendment").
The Fifth Amendment (i) extended the maturity of the Financing Agreement to
December 27, 2022, (ii) provided a $5.0 million term loan provided by the
Lenders to us under the delayed draw feature of the Financing Agreement, (iii)
extended the period by which an applicable premium payable to the Lenders will
be calculated to December 31, 2021, (iv) modified certain definitions and
concepts to account for our recent acquisition of properties from Blackjewel,
(v) permitted the disposition of the Pennyrile mining complex and (vi) provided
for the payment of additional fees to the Lenders, including a consent fee of
$1.0 million, an amendment fee of $825,000 and an increase in the lender exit
fee of 1.00% to a total exit fee of 7.0% of the amount of term loans made under
the Financing Agreement that is payable at the maturity of the Financing
Agreement.



On March 2, 2020, we entered into a sixth amendment (the "Sixth Amendment") to
the Financing Agreement. The Sixth Amendment, among other things, provides a
consent by the Origination Agent to a $3.0 million delayed draw term loan and
increases the lender exit fee payable by the Partnership to the Lenders upon the
maturity date (or earlier termination or acceleration date) by an additional
1.0%.



Distribution Suspension



Beginning with the quarter ended June 30, 2015 and continuing through the
quarter ended December 31, 2018, we have suspended the cash distribution on our
common units. For each of the quarters ended September 30, 2014, December 31,
2014 and March 31, 2015, we announced cash distributions per common unit at
levels lower than the minimum quarterly distribution. We have not paid any
distribution on our subordinated units for any quarter after the quarter ended
March 31, 2012. The distribution suspension and prior reductions were the result
of prolonged weakness in the coal markets, which has continued to adversely
affect our cash flow.



Pursuant to our partnership agreement, our common units accrue arrearages every
quarter when the distribution level is below the minimum level of $4.45 per
unit. Since our distributions for the quarters ended September 30, 2014,
December 31, 2014 and March 31, 2015 were below the minimum level and we
altogether suspended the distribution beginning with the quarter ended June 30,
2015, we have accumulated arrearages at December 31, 2019 related to the common
unit distribution of approximately $907.2 million.



Asset Impairments-2019



We performed a comprehensive review of our current coal mining operations as
well as potential future development projects to ascertain any potential
impairment losses during 2019. We identified two properties that were impaired
based upon changes in market conditions, financing alternatives or other
factors, specifically at our Rhino Eastern and Taylorville Mining undeveloped
properties where market conditions related to any future development
deteriorated in the fourth quarter of 2019. We determined that the probability
of obtaining the financing required for these projects would be remote as of
December 31, 2019. We recorded approximately $26.0 million of total asset
impairment and related charges related to these undeveloped properties for the
year ended December 31, 2019, which is recorded on the Asset impairment and
related charges line of the consolidated statements of operations. The $26.0
million impairment included a $17.9 million impairment related to future
development of Rhino Eastern and an $8.1 million impairment related to future
development of Taylorville Mining LLC.



Factors That Impact Our Business


Our results of operations in the near term could be impacted by a number of
factors, including (1) our ability to fund our ongoing operations and necessary
capital expenditures, (2) the availability of transportation for coal shipments,
(3) poor mining conditions resulting from geological conditions or the effects
of prior mining, (4) equipment problems at mining locations, (5) adverse weather
conditions and natural disasters or (6) the availability and costs of key
supplies and commodities such as steel, diesel fuel and explosives.



  65







On a long-term basis, our results of operations could be impacted by, among
other factors, (1) our ability to fund our ongoing operations and necessary
capital expenditures, (2) changes in governmental regulation, (3) the
availability and prices of competing electricity-generation fuels, (4) the
world-wide demand for steel, which utilizes metallurgical coal and can affect
the demand and prices of metallurgical coal that we produce, (5) our ability to
secure or acquire high-quality coal reserves and (6) our ability to find buyers
for coal under favorable supply contracts.



We have historically sold a majority of our coal through supply contracts and
anticipate that we will continue to do so. As of December 31, 2019, we had
commitments under supply contracts to deliver annually scheduled base quantities
of coal as follows:



                  Year         Tons            Number of customers
                          (in thousands)
                  2020              1,734                        12
                  2021                400                         3
                  2022                250                         3



Some of the contracts have sales price adjustment provisions, subject to certain limitations and adjustments, based on a variety of factors and indices.





Results of Operations



Segment Information



As of December 31, 2019, we have three reportable business segments: Central
Appalachia, Northern Appalachia and Rhino Western. Additionally, we have an
Other category that includes our ancillary businesses. Our Central Appalachia
segment consists of three mining complexes: Tug River, Rob Fork and Jewell
Valley, which, as of December 31, 2019, together included five underground
mines, three surface mines and four preparation plants and loadout facilities in
eastern Kentucky, Virginia and southern West Virginia. Our Northern Appalachia
segment consists of the Hopedale mining complex and the Leesville field. The
Hopedale mining complex, located in northern Ohio, includes one underground mine
and one preparation plant and loadout facility as of December 31, 2019. Our
Rhino Western segment includes one underground mine in the Western Bituminous
region at our Castle Valley mining complex in Utah. Our Other category is
comprised of our ancillary businesses.



Evaluating Our Results of Operations


Our management uses a variety of non-GAAP financial measurements to analyze our
performance, including (1) Adjusted EBITDA, (2) coal revenues per ton and (3)
cost of operations per ton.



Adjusted EBITDA. The discussion of our results of operations below includes
references to, and analysis of, our segments' Adjusted EBITDA results. Adjusted
EBITDA represents net income before deducting interest expense, income taxes and
depreciation, depletion and amortization, while also excluding certain non-cash
and/or non-recurring items. Adjusted EBITDA is used by management primarily as a
measure of our segments' operating performance. Adjusted EBITDA should not be
considered an alternative to net income, income from operations, cash flows from
operating activities or any other measure of financial performance or liquidity
presented in accordance with GAAP. Because not all companies calculate Adjusted
EBITDA identically, our calculation may not be comparable to similarly titled
measures of other companies. Please read "-Reconciliation of Adjusted EBITDA"
for reconciliations of Adjusted EBITDA to net income by segment for each of

the
periods indicated.



Coal Revenues Per Ton. Coal revenues per ton represents coal revenues divided by
tons of coal sold. Coal revenues per ton is a key indicator of our effectiveness
in obtaining favorable prices for our product.



  66







Cost of Operations Per Ton. Cost of operations per ton sold represents the cost
of operations (exclusive of DD&A) divided by tons of coal sold. Management uses
this measurement as a key indicator of the efficiency of operations.



Summary. (Unless otherwise specified, the following discussion of the results of
operations for the years ended December 31, 2019 and 2018 excludes operating
results relating to Pennyrile. The Pennyrile operating results are recorded as
discontinued operations in our consolidated statements of operations.)



The following table sets forth certain information regarding our revenues, operating expenses, other income and expenses, and operational data for years ended December 31, 2019 and 2018:

Year Ended December 31, 2019 Compared to Year Ended December 31, 2018





Revenues. For the year ended December 31, 2019, our total revenues decreased to
$181.0 million from $196.5 million for the year ended December 31, 2018. We sold
approximately 3.0 million tons of coal during the year ended December 31, 2019,
which was a decrease of 0.3 million tons, or a 9.7% decrease, from the 3.3
million tons of coal sold during the year ended December 31, 2018. The decrease
in revenue and tons sold was primarily the result of decreased sales in Central
Appalachia due to lower demand for met and steam coal produced in this region.



Cost of Operations. Total cost of operations increased by $3.8 million or 2.4%
to $167.4 million for the year ended December 31, 2019 as compared to $163.6
million for the year ended December 31, 2018. Our cost of operations per ton was
$56.00 for the year ended December 31, 2019, an increase of $6.59, or 13.3%,
from the year ended December 31, 2018. The increase in cost of operations per
ton was primarily due to the increase in cost of operations at our Northern
Appalachia operations as we encountered adverse geological conditions during
2019. We also experienced an increase in the cost of labor at all of our
segments and an increase in equipment maintenance at our Central Appalachia
operations.



Freight and Handling. Total freight and handling cost decreased to $4.7 million
for the year ended December 31, 2019 as compared to $9.1 million for the year
ended December 31, 2018. The decrease in freight and handling costs was
primarily the result of fewer export sales that require us to pay railroad
transportation to the port of export. We also incurred $1.1million in demurrage
charges during 2018 due to rail transportation constraints that caused shipments
to be delayed to the port of export.



Depreciation, Depletion and Amortization. Total DD&A expense for the year ended
December 31, 2019 was $14.5 million as compared to $14.4 million for the year
ended December 31, 2018.


For the year ended December 31, 2019, our depreciation expense increased to $10.4 million compared to $10.3 million for the year ended December 31, 2018.





For the year ended December 31, 2019, our depletion expense decreased to $1.6
million compared to $1.7 million for the year ended December 31, 2018. This
decrease is primarily due to the decrease in tons produced in 2019 compared

to
2018.


For the year ended December 31, 2019, our amortization expense was approximately $2.5 million compared to $2.4 million for the year ended December 31, 2018.





Selling, General and Administrative. SG&A expense for the year ended December
31, 2019 increased to $14.9 million as compared to $12.6 million for the year
ended December 31, 2018 primarily due to a $2.0 million expense recorded as the
result of an agreement reached with a third party to assume the surety bonds
associated with Sands Hill Mining LLC that had not been transferred from our
bond portfolio by the purchaser of Sands Hill Mining LLC as required by the sale
agreement executed with the purchaser in November 2017.



Interest Expense. Interest expense for the year ended December 31, 2019 decreased to $7.9 million as compared to $8.5 million for the year ended December 31, 2018. This decrease was primarily due to the lower average outstanding debt balance and a lower effective interest rate on our Financing Agreement during 2019.





Net Loss. Net loss was approximately $47.6 million for the year ended December
31, 2019 compared to a net loss of approximately $8.3 million for the year ended
December 31, 2018. The net loss for the year ended December 31, 2019 was
primarily the result of $26.0 million in asset impairments. The asset
impairments and related charges included a $17.9 million impairment related to
future development of Rhino Eastern and an $8.1 million impairment related to
future development of Taylorville Mining LLC (please read -"Asset
Impairments-2019" above for additional discussion). In addition to the asset
impairments, we also experienced a decrease in total revenue of $15.5 million
primarily due to fewer tons of coal sold from our Central Appalachia mining

operation.



  68







Adjusted EBITDA. Adjusted EBITDA from continuing operations decreased to $1.5
million for the year ended December 31, 2019 as compared to $19.4 million for
the year ended December 31, 2018. The decrease in Adjusted EBITDA during the
year ended December 31, 2019 was primarily due to the decrease in revenue
discussed above and an increase in labor costs across all segments. Including
net loss from discontinued operations of approximately $51.9 million, which
related to our Pennyrile Energy operation sold in September 2019, our net loss
was $99.5 million and Adjusted EBITDA was $(5.7) million for the year ended
December 31, 2019. Including net loss from discontinued operations of $7.7
million, which also related to our Pennyrile Energy operation, our net loss was
$16.0 million and Adjusted EBITDA was $19.6 million for the year ended December
31, 2018.

* Percentages and per ton amounts are calculated based on actual amounts and not


  the rounded amounts presented in this table.




Tons of coal sold in our Central Appalachia segment decreased by approximately
21.6% to approximately 1.5 million tons for the year ended December 31, 2019
compared to the year ended December 31, 2018, primarily due to a decrease in
demand for met and steam coal tons from this region.



Coal revenues decreased by approximately $23.7 million, or 17.0%, to
approximately $115.7 million for the year ended December 31, 2019 from
approximately $139.4 million for the year ended December 31, 2018. This decrease
was primarily due to the decrease in demand for met and steam coal tons sold
from this region. Coal revenues per ton for our Central Appalachia segment
increased by $4.33, or 5.8%, to $79.11 per ton for the year ended December 31,
2019 as compared to $74.78 for the year ended December 31, 2018. This increase
was primarily due to the increase in contracted sale prices for our met and

steam coal from this region.



  69







Cost of operations decreased by $2.6 million, or 2.4%, to $109.5 million for the
year ended December 31, 2019 from $112.1 million for the year ended December 31,
2018. Our cost of operations per ton of $74.89 for the year ended December 31,
2019 increased 24.5% compared to $60.16 per ton for the year ended December 31,
2018. Total cost of operations per ton increased in Central Appalachia due to
the decrease in coal tons sold resulting in fixed costs being allocated to fewer
tons during 2019. We also experienced an increase in labor and maintenance costs
in this region during 2019 compared to 2018.



Total freight and handling cost decreased to $3.5 million for the year ended
December 31, 2019 from approximately $9.1 million for the year ended December
31, 2018. The decrease in freight and handling costs was primarily the result of
fewer export sales that require us to pay railroad transportation to the port of
export during 2019. We also incurred $1.1 in demurrage charges during 2018 due
to rail transportation constraints that caused shipments to be delayed to the
port of export.



For our Central Appalachia segment, net loss was approximately $16.2 million for
the year ended December 31, 2019, a decrease of $25.0 million in net income as
compared to the year ended December 31, 2018. The net loss was impacted by the
$17.9 million asset impairment charge related to Rhino Eastern properties as
discussed earlier and the decrease in coal revenues during 2019.



Central Appalachia Overview of Results by Product. Additional information for
the Central Appalachia segment detailing the types of coal produced and sold,
premium high-vol met coal and steam coal for the years ended December 31, 2019
and 2018, is presented below. Note that our Northern Appalachia and Rhino

For our Northern Appalachia segment, tons of coal sold increased by
approximately 16.3% for the year ended December 31, 2019 compared to the year
ended December 31, 2018 as we experienced increased demand for coal from this
region.



Coal revenues were approximately $23.8 million for the year ended December 31,
2019, an increase of approximately $5.6 million, or 30.5%, from approximately
$18.2 million for the year ended December 31, 2018. Coal revenues per ton
increased by $5.26 or 12.2% to $48.31 per ton for the year ended December 31,
2019, as compared to $43.05 for the year ended December 31, 2018, which was
primarily due to an increase in contracted sale prices for tons sold from our
Hopedale complex compared to the prior year.



Cost of operations increased by $7.3 million, or 31.2%, to $30.8 million for the
year ended December 31, 2019 from $23.5 million for the year ended December 31,
2018. Our cost of operations per ton was $62.63 for the year ended December 31,
2019, an increase of $7.15, or 12.9%, compared to $55.48 for the year ended
December 31, 2018. The increase in total cost of operations and cost of
operations per ton was primarily the result of adverse geological conditions we
encountered during 2019. We also experienced an increase in operating expenses
including labor, maintenance, roof support and contract services.



Net loss in our Northern Appalachia segment was $8.4 million for the year ended
December 31, 2019 compared to net loss of $4.4 million for the year ended
December 31, 2018. The increase in net loss for the year ended December 31, 2019
was primarily due to the increase in the cost of operations partially offset by
the increase in contracted sale prices of tons sold compared to the same period
in 2018.

Tons of coal sold from our Rhino Western segment increased by approximately 1.3% for the year ended December 31, 2019 compared to the same period in 2018.





Coal revenues increased by approximately $3.2 million, or 9.0%, to approximately
$39.4 million for the year ended December 31, 2019 from approximately $36.2
million for the year ended December 31, 2018. Coal revenues per ton for our
Rhino Western segment increased by $2.70 or 7.6% to $38.10 per ton for the year
ended December 31, 2019 as compared to $35.40 per ton for the year ended
December 31, 2018 due to higher contracted sale prices.



Cost of operations decreased by $0.7 million, or 2.3%, to $29.8 million for the
year ended December 31, 2019 from $30.5 million for the year ended December 31,
2018. Our cost of operations per ton was $28.77 for the year ended December 31,
2019, a decrease of $1.03, or 3.5%, compared to $29.80 for the year ended
December 31, 2018. Total cost of operations and cost of operations per ton
decreased slightly for the year ended December 31, 2019 compared to 2018
primarily due to lower operating costs.



Net income in our Rhino Western segment was $4.5 million for the year ended December 31, 2019, compared to net income of $1.4 million for the year ended December 31, 2018. This increase in net income was primarily the result of higher contracted sale prices for tons sold at our Castle Valley operation.

Other revenues for our Other category were $0.1 million for the year ended December 31, 2019 compared to approximately $0.2 million for the year ended December 31, 2018.


For the Other category, we had net loss from continuing operations of $27.5
million for the year ended December 31, 2019 as compared to net loss from
continuing operations of $14.1 million for the year ended December 31, 2018. Net
loss for the year ended December 31, 2019 was impacted by the $8.1 million asset
impairment charge related to Taylorville Mining LLC and the $2.0 million SG&A
expense discussed above.


Reconciliation of Adjusted EBITDA


The following tables present reconciliations of Adjusted EBITDA to the most
directly comparable GAAP financial measures for each of the periods indicated.
Adjusted EBITDA excludes the effect of certain non-cash and/or non-recurring
items. Adjusted EBITDA is used by management primarily as a measure of our
segments' operating performance. Adjusted EBITDA should not be considered an
alternative to net income, income from operations, cash flows from operating
activities or any other measure of financial performance or liquidity presented
in accordance with GAAP. Because not all companies calculate Adjusted EBITDA
identically, our calculation may not be comparable to similarly titled measures
of other companies.

† Calculated based on actual amounts and not the rounded amounts presented in

this table.

* Totals may not foot due to rounding.

(1) During the year ended December 31, 2019, we recorded asset impairment

charges of $26.0 million, including a $17.9 million impairment related to

future development of Rhino Eastern and $8.1 million related to the future

development of Taylorville Mining LLC.

(2) During the year ended December 31, 2019, we sold parcels of land owned in

western Colorado for proceeds less than our carrying value of the land that

resulted in losses of approximately $0.8 million. This land is a non-core

asset that we chose to monetize despite the loss incurred.

(3) We recorded an impairment loss of $38.7 million associated with the sale of

our Pennyrile assets for year ended December 31, 2019. The impairment loss of

$38.7 million is recorded in discontinued operations for the year ended
    December 31, 2019.



(4) During the year ended December 31, 2018, we recorded provisions for doubtful

accounts of approximately $0.9 million, which primarily related to a small

number of customers in Central Appalachia.

(5) During the year ended December 31, 2018, the gain recognized from the sales

of our TUSK stock was impacted by the adoption of ASU 2016-01, which resulted

in $3.7 million of economic benefit being reclassified to equity from Other


    Comprehensive Income instead of being recognized in net income.

    We believe that the isolation and presentation of these specific items to
    arrive at Adjusted EBITDA is useful because it enhances investors'

understanding of how we assess the performance of our business. We believe

the adjustment of these items provide investors with additional information

that they can utilize in evaluating our performance. Additionally, we believe

the isolation of these items provide investors with enhanced comparability to


    prior and future periods of our operating results.

Liquidity and Capital Resources





Liquidity



As of December 31, 2019, our available liquidity was $0.1 million. We also have
a delayed draw term loan commitment in the amount of $25 million contingent upon
the satisfaction of certain conditions precedent specified in the financing
agreement discussed below.



On December 27, 2017, we entered into a Financing Agreement, which provides us
with a multi-draw loan in the original aggregate principal amount of $80
million. The total principal amount is divided into a $40 million commitment,
the conditions for which were satisfied at the execution of the Financing
Agreement and a $40 million additional commitment that was contingent upon the
satisfaction of certain conditions precedent specified in the Financing
Agreement. As of December 31, 2019, we had utilized $15 million of the $40
million additional commitment, which results in $25 million of the additional
commitment remaining. We used approximately $17.3 million of the initial
Financing Agreement net proceeds to repay all amounts outstanding and terminate
the amended and restated credit agreement with PNC Bank, National Association,
as Administrative Agent. The Financing Agreement initially had a termination
date of December 27, 2020, which was amended to December 27, 2022 per the fifth
amendment to the Financing Agreement discussed further below.



Our business is capital intensive and requires substantial capital expenditures
for purchasing, upgrading and maintaining equipment used in developing and
mining our reserves, as well as complying with applicable environmental and mine
safety laws and regulations. Our principal liquidity requirements are to finance
current operations, fund capital expenditures, including acquisitions from time
to time, and service our debt. Historically, our sources of liquidity included
cash generated by our operations, cash available on our balance sheet and
issuances of equity securities.



Beginning in the later part of the third quarter of 2019, we have experienced
significantly weaker market demand and have seen prices move lower for the
qualities of met and steam coal we produce. This downward price trend has been
exacerbated by the recent coronavirus pandemic. In response to this reduced
demand and to the significant health threats to our employees, on March 20,
2020, we temporarily idled production at several of our mines. We will continue
to monitor conditions to ensure the health and welfare of our employees. We do
not expect the idling of the coal production activities will affect our ability
to fulfill current customer commitments, as loading and shipping crews will
remain in place to ship coal from existing inventories.



If we continue to experience weak demand and prices continue to lower for our
met and steam coal, we may not be able to continue to give the required
representations or meet all of the covenants and restrictions included in our
Financing Agreement. If we violate any of the covenants or restrictions in our
Financing Agreement, including the fixed-charge coverage ratio, some or all of
our indebtedness may become immediately due and payable, and our Lenders may not
be willing to make any loans under the additional commitment available under our
Financing Agreement. If we are unable to give a required representation or we
violate a covenant or restriction, then we will need a waiver from our Lenders
under our Financing Agreement, or they may declare an event of default and,
after applicable specified cure periods, all amounts outstanding under the
Financing Agreement would become immediately due and payable. Although we
believe our Lenders are well secured under the terms of our Financing Agreement,
there is no assurance that the Lenders would agree to any such waiver. Failure
to obtain financing or to generate sufficient cash flow from operations could
cause us to further curtail our operations and reduce spending and alter our
business plan. We are currently considering alternatives to address our
liquidity and balance sheet issues, such as selling additional assets or seeking
merger opportunities, and depending on the urgency of our liquidity constraints,
we may be required to pursue such an option at an inopportune time.



  75









As of December 31, 2019, we are unable to demonstrate that we have sufficient
liquidity to operate our business over the next twelve months from the date of
filing our Annual Report on Form 10-K and thus substantial doubt is raised about
our ability to continue as a going concern. Accordingly, our independent
registered public accounting firm has included an emphasis paragraph with
respect to our ability to continue as a going concern in its report on our
consolidated financial statements for the year ended December 31, 2019. The
presence of the going concern emphasis paragraph in our auditors' report may
have an adverse impact on our relationship with third parties with whom we do
business, including our customers, vendors, lenders and employees, making it
difficult to raise additional financing to the extent needed to conduct normal
operations. As a result, our business, results of operations, financial
condition and prospects could be materially adversely affected.



We evaluated our Financing Agreement at December 31, 2019 to determine whether
the debt liability should be classified as a long-term or current liability on
our consolidated statements of financial position. We determined that we were in
violation of certain debt covenants in the financing agreement as of December
31, 2019 and the Lenders were unwilling to grant a waiver to us for these events
of default as of the filing date of this Form 10-K. The Financing Agreement
contains negative covenants that restrict our ability to, among other things,
permit the trailing nine month fixed charge coverage ratio of us and our
subsidiaries to be less than 1.20 to 1.00. The Financing Agreement also requires
us to receive an annual unqualified audit opinion from our external audit firm
that does not include an emphasis paragraph on our ability to continue as a
going concern. As of December 31, 2019, our fixed charge coverage ratio was less
than 1.20 to 1.00 and our annual report on Form 10-K includes an audit opinion
from our external auditors that includes an emphasis paragraph regarding our
ability to continue as a going concern. Based upon these covenant violations,
our debt liability is currently callable by the Lenders and we reclassified

the
debt liability as current.



Debt issuance costs related to the debt liability have also been reclassified to
current. However, since we are currently in negotiations with our Lenders, we
have not changed the amortization period of these costs. Included in debt costs
are the exit fees described further in Note 11, which absent a waiver, are also
callable with the accompanying debt as of December 31, 2019. (Please read Note
11 for additional discussion of our financing agreement).



We continue to take measures, including the suspension of cash distributions on
our common and subordinated units and cost and productivity improvements, to
enhance and preserve our liquidity in order to fund our ongoing operations and
necessary capital expenditures and meet our financial commitments and debt

service obligations.



Cash Flows



Net cash used in operating activities was $11.4 million for the year ended
December 31, 2019 as compared net cash provided by operating activities of $18.6
million for the year ended December 31, 2018. This decrease in cash provided by
operating activities was primarily the result of higher net loss and negative
working capital changes, including increases in our inventory during the fourth
quarter of 2019 due to the weak coal market conditions.



Net cash provided by investing activities was $1.6 million for the year ended
December 31, 2019 as compared to net cash used in investing activities of $7.6
million for the year ended December 31, 2018. The decrease in cash used in
investing activities was primarily due to lower capital expenditures in 2019
compared to 2018.



Net cash provided by financing activities was $3.7 million for the year ended
December 31, 2019, which was primarily attributable to proceeds from our
Financing Agreement and other debt partially offset by payment of the
distribution on the Series A preferred units and repayments of other debt. Net
cash used in financing activities was $26.0 million for the year ended December
31, 2018, which was primarily attributable to payments on debt, deposits paid on
our workers' compensation and surety bond programs and payment of the
distribution on the Series A preferred units partially offset by proceeds from
our Financing Agreement.

Capital Expenditures



Our mining operations require investments to expand, upgrade or enhance existing
operations and to meet environmental and safety regulations. Maintenance capital
expenditures are those capital expenditures required to maintain our long-term
operating capacity. For example, maintenance capital expenditures include
expenditures associated with the replacement of equipment and coal reserves,
whether through the expansion of an existing mine or the acquisition or
development of new reserves, to the extent such expenditures are made to
maintain our long-term operating capacity. Expansion capital expenditures are
those capital expenditures that we expect will increase our operating capacity
over the long term. Examples of expansion capital expenditures include the
acquisition of reserves, acquisition of equipment for a new mine or the
expansion of an existing mine to the extent such expenditures are expected to
expand our long-term operating capacity.



Actual maintenance capital expenditures for the year ended December 31, 2019
were approximately $7.8 million. These amounts were primarily used to rebuild,
repair or replace older mining equipment. Expansion capital expenditures for the
year ended December 31, 2019 were approximately $6.3 million, which were
primarily related to expenditures at our new Jewell Valley mines. For the year
ended December 31, 2020, we have budgeted $10 million to $12 million for
maintenance capital expenditures and $1 million to $2 million for expansion

capital expenditures.



Financing Agreement



On December 27, 2017, we entered into a Financing Agreement, pursuant to which
the Lenders agreed to provide us with a multi-draw term loan in the original
aggregate principal amount of $80 million, subject to the terms and conditions
set forth in the Financing Agreement. The total principal amount is divided into
a $40 million commitment, the conditions of which were satisfied at the
execution of the Financing Agreement (the "Effective Date Term Loan Commitment")
and a $40 million additional commitment that was contingent upon the
satisfaction of certain conditions precedent specified in the Financing
Agreement ("Delayed Draw Term Loan Commitment"). As of December 31, 2019, we
have utilized $15 million of the $40 million additional commitment, which
results in $25 million of the additional commitment remaining. Loans made
pursuant to the Financing Agreement are secured by substantially all of our
assets. The Financing Agreement originally had a termination date of December
27, 2020, which was amended to December 27, 2022 per the fifth amendment to the
Financing Agreement discussed further below.



Loans made pursuant to the Financing Agreement are, at our option, either
"Reference Rate Loans" or "LIBOR Rate Loans." Reference Rate Loans bear interest
at the greatest of (a) 4.25% per annum, (b) the Federal Funds Rate plus 0.50%
per annum, (c) the LIBOR Rate (calculated on a one-month basis) plus 1.00% per
annum or (d) the Prime Rate (as published in the Wall Street Journal) or if no
such rate is published, the interest rate published by the Federal Reserve Board
as the "bank prime loan" rate or similar rate quoted therein, in each case, plus
an applicable margin of 9.00% per annum (or 12.00% per annum if we have elected
to capitalize an interest payment pursuant to the PIK Option, as described
below). LIBOR Rate Loans bear interest at the greater of (x) the LIBOR for such
interest period divided by 100% minus the maximum percentage prescribed by the
Federal Reserve for determining the reserve requirements in effect with respect
to eurocurrency liabilities for any Lender, if any, and (y) 1.00%, in each case,
plus 10.00% per annum (or 13.00% per annum if we have elected to capitalize an
interest payment pursuant to the PIK Option). Interest payments are due on a
monthly basis for Reference Rate Loans and one-, two- or three-month periods, at
our option, for LIBOR Rate Loans. If there is no event of default occurring or
continuing, we may elect to defer payment on interest accruing at 6.00% per
annum by capitalizing and adding such interest payment to the principal amount
of the applicable term loan (the "PIK Option").



  77







Commencing December 31, 2018, the principal for each loan made under the
Financing Agreement will be payable on a quarterly basis in an amount equal to
$375,000 per quarter, with all remaining unpaid principal and accrued and unpaid
interest originally due on December 27, 2020 (see discussion of fifth amendment
below). In addition, we must make certain prepayments over the term of any loans
outstanding, including: (i) the payment of 25% of Excess Cash Flow (as that term
is defined in the Financing Agreement) for each fiscal year, commencing with
respect to the year ending December 31, 2019, (ii) subject to certain
exceptions, the payment of 100% of the net cash proceeds from the dispositions
of certain assets, the incurrence of certain indebtedness or receipts of cash
outside of the ordinary course of business, and (iii) the payment of the excess
of the outstanding principal amount of term loans outstanding over the amount of
the Collateral Coverage Amount (as that term is defined in the Financing
Agreement). In addition, the Lenders are entitled to (i) certain fees, including
1.50% per annum of the unused Delayed Draw Term Loan Commitment for as long as
such commitment exists, (ii) for the 12-month period following the execution of
the Financing Agreement, a make-whole amount equal to the interest and unused
Delayed Draw Term Loan Commitment fees that would have been payable but for the
occurrence of certain events, including among others, bankruptcy proceedings or
the termination of the Financing Agreement by us, and (iii) audit and collateral
monitoring fees and origination and exit fees.



The Financing Agreement requires us to comply with several affirmative covenants
at any time loans are outstanding, including, among others: (i) the requirement
to deliver monthly, quarterly and annual financial statements, (ii) the
requirement to periodically deliver certificates indicating, among other things,
(a) compliance with terms of Financing Agreement and ancillary loan documents,
(b) inventory, accounts payable, sales and production numbers, (c) the
calculation of the Collateral Coverage Amount (as that term is defined in the
Financing Agreement), (d) projections for the business and (e) coal reserve
amounts; (iii) the requirement to notify the Administrative Agent of certain
events, including events of default under the Financing Agreement, dispositions,
entry into material contracts, (iv) the requirement to maintain insurance,
obtain permits, and comply with environmental and reclamation laws (v) the
requirement to sell up to $5.0 million of shares in Mammoth Inc. and use the net
proceeds therefrom to prepay outstanding term loans and (vi) establish and
maintain cash management services and establish a cash management account and
deliver a control agreement with respect to such account to the Collateral
Agent. The Financing Agreement also contains negative covenants that restrict
our ability to, among other things: (i) incur liens or additional indebtedness
or make investments or restricted payments, (ii) liquidate or merge with another
entity, or dispose of assets, (iii) change the nature of our respective
businesses; (iv) make capital expenditures in excess, or, with respect to
maintenance capital expenditures, lower than, specified amounts, (v) incur
restrictions on the payment of dividends, (vi) prepay or modify the terms of
other indebtedness, (vii) permit the Collateral Coverage Amount to be less than
the outstanding principal amount of the loans outstanding under the Financing
Agreement or (viii) permit the trailing six month Fixed Charge Coverage Ratio to
be less than 1.20 to 1.00 commencing with the six-month period ending June

30,
2018.



The Financing Agreement contains customary events of default, following which
the Collateral Agent may, at the request of Lenders, terminate or reduce all
commitments and accelerate the maturity of all outstanding loans to become due
and payable immediately together with accrued and unpaid interest thereon and
exercise any such other rights as specified under the Financing Agreement and
ancillary loan documents.



On April 17, 2018, we amended our Financing Agreement to allow for certain
activities, including a sale leaseback of certain pieces of equipment, the
extension of the due date for lease consents required under the Financing
Agreement to June 30, 2018 and the distribution to holders of the Series A
preferred units of $6.0 million (accrued in the consolidated financial
statements at December 31, 2017). Additionally, the amendments provided that the
Partnership could sell additional shares of Mammoth Inc. stock and retain 50% of
the proceeds with the other 50% used to reduce debt. We reduced our outstanding
debt by $3.4 million with proceeds from the sale of Mammoth Inc. stock in the
second quarter of 2018.



On July 27, 2018, we entered into a consent $5.0 million loan from the Delayed
Draw Term Loan Commitment, which was repaid in full on October 26, 2018 pursuant
to the terms of the consent. The consent also included a waiver of the
requirements relating to the use of proceeds of any sale of the shares of
Mammoth Inc. set forth in the consent to the Financing Agreement, dated as of
April 17, 2018 and also waived any Event of Default that arose or would
otherwise arise under the Financing Agreement for failing to comply with the
Fixed Charge Coverage Ratio for the six months ended June 30, 2018.



On November 8, 2018, we entered into a consent with our Lenders related to the
Financing Agreement. The consent included the Lenders' agreement to waive any
Event of Default that arose or would otherwise arise under the Financing
Agreement for failing to comply with the Fixed Charge Coverage Ratio for the six
months ended September 30, 2018.



  78







On December 20, 2018, we entered into a limited consent and Waiver to the
Financing Agreement. The Waiver related to sales of certain real property in
Western Colorado, the net proceeds of which were required to be used to reduce
our debt under the Financing Agreement. As of the date of the Waiver, we had
sold 9 individual lots in smaller transactions. Rather than transmitting net
proceeds with respect to each individual transaction, we agreed with the Lenders
in principle to delay repayment until an aggregate payment could be made at the
end of 2018. On December 18, 2018, we used the sale proceeds of approximately
$379,000 to reduce the debt. The Waiver (i) contains a ratification by the
Lenders of the sale of the individual lots to date and waives the associated
technical defaults under the Financing Agreement for not making immediate
payments of net proceeds therefrom, (ii) permits the sale of certain specified
additional lots and (iii) subject to Lender consent, permits the sale of other
lots on a going forward basis. The net proceeds of future sales will be held by
us until a later date to be determined by the Lenders.



On February 13, 2019, we entered into a second amendment to the Financing
Agreement. The Amendment provided the Lender's consent for us to pay a one-time
cash distribution on February 14, 2019 to the Series A Preferred Unitholders not
to exceed approximately $3.2 million. The Amendment allowed us to sell our
remaining shares of Mammoth Energy Services, Inc. and utilize the proceeds for
payment of the one-time cash distribution to the Series A Preferred Unitholders
and waived the requirement to use such proceeds to prepay the outstanding
principal amount outstanding under the Financing Agreement. The Amendment also
waived any Event of Default that has or would otherwise arise under Section
9.01(c) of the Financing Agreement solely by reason of us failing to comply with
the Fixed Charge Coverage Ratio covenant in Section 7.03(b) of the Financing
Agreement for the fiscal quarter ending December 31, 2018. The Amendment
included an amendment fee of approximately $0.6 million payable by us on May 13,
2019 and an exit fee equal to 1% of the principal amount of the term loans made
under the Financing Agreement that is payable on the earliest of (w) the final
maturity date of the Financing Agreement, (x) the termination date of the
Financing Agreement, (y) the acceleration of the obligations under the Financing
Agreement for any reason, including, without limitation, acceleration in
accordance with Section 9.01 of the Financing Agreement, including as a result
of the commencement of an insolvency proceeding and (z) the date of any
refinancing of the term loan under the Financing Agreement. The Amendment
amended the definition of the Make-Whole Amount under the Financing Agreement to
extend the date of the Make-Whole Amount period to December 31, 2019.



On May 8, 2019, we entered into Third Amendment to the Financing Agreement. The
Third Amendment included the Lender's agreement to waive any Event of Default
that arose or would otherwise arise under the Financing Agreement for failing to
comply with the Fixed Charge Coverage Ratio for the six months ended March 31,
2019. The Third Amendment increased the original exit fee of 3.0% to 6.0%. The
original exit fee of 3% was included in the Financing Agreement at the execution
date and the increase of the total exit fee to 6% was included as part of the
amendment dated February 13, 2019 discussed above and this Third Amendment. The
exit fee is applied to the principal amount of the loans made under the
Financing Agreement that is payable on the earliest of (a) the final maturity
date, (b) the termination date of the Financing agreement for any reason, (c)
the acceleration of the obligations in the Financing Agreement for any reason
and (d) the date of any refinancing of the term loan under the Financing
Agreement.



On August 16, 2019, we entered into the Fourth Amendment to the Financing
Agreement originally executed on December 27, 2017 with the Lenders. The Fourth
Amendment provides a $5.0 million term loan provided by the Lenders to us under
the delayed draw feature of the Financing Agreement, and extended the period by
which an applicable premium payable to the Lenders will be calculated to the
final maturity date.



On September 6, 2019, we entered into the Fifth Amendment to the Financing
Agreement. The Fifth Amendment (i) extended the maturity of the Financing
Agreement to December 27, 2022, (ii) provided us with a $5.0 million term loan
provided by the Lenders under the delayed draw feature of the Financing
Agreement, (iii) extended the period by which an applicable premium payable to
the Lenders will be calculated to December 31, 2021, (iv) modified certain
definitions and concepts to account for our recent acquisition of properties
from Blackjewel, (v) permitted the disposition of the Pennyrile mining complex
and (vi) provided for the payment of additional fees to the Lenders, including a
consent fee of $1.0 million, an amendment fee of $825,000 and an increase in the
lender exit fee of 1.00% to a total exit fee of 7.0% of the amount of term loans
made under the Financing Agreement that is payable upon the maturity of the
Financing Agreement.



On March 2, 2020, we entered into a sixth amendment (the "Sixth Amendment") to
the Financing Agreement. The Sixth Amendment, among other things, provides a
consent by the Origination Agent to a $3.0 million delayed draw term loan and
increases the lender exit fee payable by the Partnership to the Lenders upon the
maturity date (or earlier termination or acceleration date) by an additional
1.0%.



  79







At December 31, 2019, $27.5 million was outstanding under the financing
agreement at a variable interest rate of Libor plus 10.00% (11.80% at December
31, 2019), $5.0 million of borrowings outstanding at a variable interest rate of
Libor plus 10.00% (11.74% at December 31, 2019) and $5.0 million of borrowings
outstanding at a variable interest rate of Libor plus 10.00% (11.71% at December
31, 2019).



Common Unit Warrants



On December 27, 2017, we entered into a warrant agreement with certain parties
that are also parties to the Financing Agreement discussed above. The warrant
agreement included the issuance of a total of 683,888 Common Unit Warrants at an
exercise price of $1.95 per unit, which was the closing price of our units on
the OTC market as of December 27, 2017. The Common Unit Warrants have a five
year expiration date. The Common Unit Warrants and the Rhino common units after
exercise are both transferable, subject to applicable US securities laws. The
Common Unit Warrant exercise price is $1.95 per unit, but the price per unit
will be reduced by future common unit distributions and other further
adjustments in price included in the warrant agreement for transactions that are
dilutive to the amount of Rhino's common units outstanding. The warrant
agreement includes a provision for a cashless exercise where the warrant holders
can receive a net number of common units. Per the warrant agreement, the
warrants are detached from the Financing Agreement and fully transferable.

Off-Balance Sheet Arrangements





In the normal course of business, we are a party to off-balance sheet
arrangements that include guarantees and financial instruments with off-balance
sheet risk, such as bank letters of credit and surety bonds. No liabilities
related to these arrangements are reflected in our consolidated balance sheet,
and we do not expect any material adverse effects on our financial condition,
results of operations or cash flows to result from these off-balance sheet
arrangements.



Federal and state laws require us to secure certain long-term obligations
related to mine closure and reclamation costs. We typically secure these
obligations by using surety bonds, an off-balance sheet instrument. The use of
surety bonds is less expensive for us than the alternative of posting a 100%
cash bond or a bank letter of credit. We then provide cash collateral to secure
our surety bonding obligations in an amount up to a certain percentage of the
aggregate bond liability that we negotiate with the surety companies. To the
extent that surety bonds become unavailable, we would seek to secure our
reclamation obligations with letters of credit, cash deposits or other suitable
forms of collateral.



As of December 31, 2019, we had $7.9 million in cash collateral held by
third-parties of which $3.0 million serves as collateral for approximately $41.6
million in surety bonds outstanding that secure the performance of our
reclamation obligations. The other $4.9 million serves as collateral for our
self-insured workers' compensation program. Of the $41.6 million of surety
bonds, approximately $0.4 million relates to surety bonds for Deane Mining, LLC,
which have not been transferred or replaced by the buyer of Deane Mining LLC as
was agreed to by the parties as part of the transaction. We can provide no
assurances that a surety company will underwrite the surety bonds of the
purchaser of Deane Mining LLC, nor are we aware of the actual amount of
reclamation at any given time. Further, if there was a claim under these surety
bonds prior to the transfer or replacement of such bonds by the buyer of Deane
Mining, LLC, we may be responsible to the surety company for any amounts it pays
in respect of such claim. While the buyer is required to indemnify us for
damages, including reclamation liabilities, pursuant to the agreements governing
the sales of this entity, we may not be successful in obtaining any indemnity or
any amounts received may be inadequate. See Part I "Business-Regulation and
Laws-Surety Bonds."



Critical Accounting Policies and Estimates





Our financial statements are prepared in accordance with accounting principles
that are generally accepted in the United States. The preparation of these
financial statements requires management to make estimates and judgments that
affect the reported amount of assets, liabilities, revenues and expenses as well
as the disclosure of contingent assets and liabilities. Management evaluates its
estimates and judgments on an on-going basis. Management bases its estimates and
judgments on historical experience and other factors that are believed to be
reasonable under the circumstances. Nevertheless, actual results may differ from
the estimates used and judgments made. Note 2 to the consolidated financial
statements included elsewhere in this annual report provides a summary of all
significant accounting policies. We believe that of these significant accounting
policies, the following may involve a higher degree of judgment or complexity.



  80







Property, Plant and Equipment



Property, plant, and equipment, including coal properties, mine development
costs and construction costs, are recorded at cost, which includes construction
overhead and interest, where applicable. Expenditures for major renewals and
betterments are capitalized, while expenditures for maintenance and repairs are
expensed as incurred. Mining and other equipment and related facilities are
depreciated using the straight-line method based upon the shorter of estimated
useful lives of the assets or the estimated life of each mine. Coal properties
are depleted using the units-of-production method, based on estimated proven and
probable reserves. Mine development costs are amortized using the
units-of-production method, based on estimated proven and probable reserves.
Gains or losses arising from sales or retirements are included in current
operations.



On March 30, 2005, the Financial Accounting Standards Board (FASB) ratified the
consensus reached by the Emerging Issues Task Force, or EITF, on accounting for
stripping costs in the mining industry. This accounting guidance applies to
stripping costs incurred in the production phase of a mine for the removal of
overburden or waste materials for the purpose of obtaining access to coal that
will be extracted. Under the guidance, stripping costs incurred during the
production phase of the mine are variable production costs that are included in
the cost of inventory produced and extracted during the period the stripping
costs are incurred. We have recorded stripping costs for all of our surface
mines incurred during the production phase as variable production costs that are
included in the cost of inventory produced. We define a surface mine as a
location where we utilize operating assets necessary to extract coal, with the
geographic boundary determined by property control, permit boundaries, and/or
economic threshold limits. Multiple pits that share common infrastructure and
processing equipment may be located within a single surface mine boundary, which
can cover separate coal seams that typically are recovered incrementally as the
overburden depth increases. In accordance with the accounting guidance for
extractive mining activities, we define a mine in production as one from which
saleable minerals have begun to be extracted (produced) from an ore body,
regardless of the level of production; however, the production phase does not
commence with the removal of de minimis saleable mineral material that occurs in
conjunction with the removal of overburden or waste material for the purpose of
obtaining access to an ore body. We capitalize only the development cost of the
first pit at a mine site that may include multiple pits.



Asset Impairments



We follow the accounting guidance on the impairment or disposal of property,
plant and equipment, which requires that projected future cash flows from use
and disposition of assets be compared with the carrying amounts of those assets
when potential impairment is indicated. When the sum of projected undiscounted
cash flows is less than the carrying amount, impairment losses are recognized.
In determining such impairment losses, we must determine the fair value for the
assets in question in accordance with the applicable fair value accounting
guidance. Once the fair value is determined, the appropriate impairment loss
must be recorded as the difference between the carrying amount of the assets and
their respective fair values. Also, in certain situations, expected mine lives
are shortened because of changes to planned operations. When that occurs and it
is determined that the mine's underlying costs are not recoverable in the
future, reclamation and mine closing obligations are accelerated and the mine
closing accrual is increased accordingly. To the extent it is determined that
asset carrying values will not be recoverable during a shorter mine life, a
provision for such impairment is recognized.



We performed a comprehensive review of our current coal mining operations as
well as potential future development projects to ascertain any potential
impairment losses during 2019. We identified two properties that were impaired
based upon changes in our strategic plans, market conditions or other factors,
specifically at our Rhino Eastern and Taylorville Mining undeveloped properties
where market conditions related to any future development deteriorated in the
fourth quarter of 2019. We determined that the probability of obtaining the
financing required for these projects would be remote as of December 31, 2019.
We recorded approximately $26.0 million of total asset impairment and related
charges related to these undeveloped properties for the year ended December 31,
2019, which is recorded on the Asset impairment and related charges line of the
consolidated statements of operations. The $26.0 million impairment included a
$17.9 million impairment related to future development of Rhino Eastern and an
$8.1 million impairment related to future development of Taylorville Mining

LLC.



  81







We performed a comprehensive review of our coal mining operations as well as
potential future development projects for the year ended December 31, 2018 to
ascertain any potential impairment losses. We did not record any impairment
losses for coal properties, mine development costs or coal mining equipment and
related facilities for the year ended December 31, 2018.



Asset Retirement Obligations



The accounting guidance for asset retirement obligations addresses asset
retirement obligations that result from the acquisition, construction, or normal
operation of long-lived assets. This guidance requires companies to recognize
asset retirement obligations at fair value when the liability is incurred or
acquired. Upon initial recognition of a liability, an amount equal to the
liability is capitalized as part of the related long-lived asset and allocated
to expense over the useful life of the asset. We have recorded the asset
retirement costs in Coal properties.



We estimate our future cost requirements for reclamation of land where we have
conducted surface and underground mining operations, based on our interpretation
of the technical standards of regulations enacted by the U.S. Office of Surface
Mining, as well as state regulations. These costs relate to reclaiming the pit
and support acreage at surface mines and sealing portals at underground mines.
Other reclamation costs are related to refuse and slurry ponds, as well as
holding and related termination or exit costs.



We expense contemporaneous reclamation which is performed prior to final mine
closure. The establishment of the end of mine reclamation and closure liability
is based upon permit requirements and requires significant estimates and
assumptions, principally associated with regulatory requirements, costs and
recoverable coal reserves. Annually, we review our end of mine reclamation and
closure liability and make necessary adjustments, including mine plan and permit
changes and revisions to cost and production levels to optimize mining and
reclamation efficiency. When a mine life is shortened due to a change in the
mine plan, mine closing obligations are accelerated, the related accrual is
increased and the related asset is reviewed for impairment, accordingly.



The adjustments to the liability from annual recosting reflect changes in
expected timing, cash flow, and the discount rate used in the present value
calculation of the liability. Each respective year includes a range of discount
rates that are dependent upon the timing of the cash flows of the specific
obligations. Changes in the asset retirement obligations for the year ended
December 31, 2019 were calculated with discount rates that ranged from 11.4% to
12.6%. Changes in the asset retirement obligations for the year ended December
31, 2018 were calculated with discount rates that ranged from 10.6% to 12.1%.
The discount rates changed from previous years due to changes in applicable
market indicators that are used to arrive at an appropriate discount rate. Other
recosting adjustments to the liability are made annually based on inflationary
cost increases or decreases and changes in the expected operating periods of the
mines. The related inflation rate utilized in the recosting adjustments was

2.2%
for 2019 and 2.3% for 2018.


Workers' Compensation and Pneumoconiosis ("black lung") Benefits


Certain of our subsidiaries are liable under federal and state laws to pay
workers' compensation and coal workers' black lung benefits to eligible
employees, former employees and their dependents. We currently utilize an
insurance program and state workers' compensation fund participation to secure
our on-going obligations depending on the location of the operation. Premium
expense for workers' compensation benefits is recognized in the period in which
the related insurance coverage is provided.



Our black lung benefit liability is calculated using the service cost method
that considers the calculation of the actuarial present value of the estimated
black lung obligation. The actuarial calculations using the service cost method
for our black lung benefit liability are based on numerous assumptions including
disability incidence, medical costs, mortality, death benefits, dependents

and
interest rates.



In addition, our liability for traumatic workers' compensation injury claims is
the estimated present value of current workers' compensation benefits, based on
actuarial estimates. The actuarial estimates for our workers' compensation
liability are based on numerous assumptions including claim development
patterns, mortality, medical costs and interest rates.

Revenue Recognition



We adopted ASU 2014-09, Topic 606 on January 1, 2018, using the modified
retrospective method. The adoption of Topic 606 had no impact on revenue amounts
recorded in our financial statements (See Note 19 to the consolidated financial
statements included elsewhere in this annual report for additional discussion).
Most of our revenues are generated under coal sales contracts with electric
utilities, coal brokers, domestic and non-U.S. steel producers, industrial
companies or other coal-related organizations. Revenue is recognized and
recorded when shipment or delivery to the customer has occurred, prices are
fixed or determinable and the title or risk of loss has passed in accordance
with the terms of the sales agreement. Under the typical terms of these
agreements, risk of loss transfers to the customers at the mine or port, when
the coal is loaded on the rail, barge, truck or other transportation source that
delivers coal to its destination. Advance payments received are deferred and
recognized in revenue as coal is shipped and title has passed.



Freight and handling costs paid directly to third-party carriers and invoiced
separately to coal customers are recorded as freight and handling costs and
freight and handling revenues, respectively. Freight and handling costs billed
to customers as part of the contractual per ton revenue of customer contracts is
included in coal sales revenue.



Other revenues generally consist of coal royalty revenues, coal handling and
processing revenues, rebates and rental income. With respect to other revenues
recognized in situations unrelated to the shipment of coal, we carefully review
the facts and circumstances of each transaction and do not recognize revenue
until the following criteria are met: persuasive evidence of an arrangement
exists, delivery has occurred or services have been rendered, the seller's price
to the buyer is fixed or determinable and collectability is reasonably assured.



Derivative Financial Instruments





We occasionally use diesel fuel contracts to manage the risk of fluctuations in
the cost of diesel fuel. Our diesel fuel contracts meet the requirements for the
normal purchase normal sale, or NPNS, exception prescribed by the accounting
guidance on derivatives and hedging, based on the terms of the contracts and
management's intent and ability to take physical delivery of the diesel fuel.



Income Taxes


We are considered a partnership for income tax purposes. Accordingly, the partners report our taxable income or loss on their individual tax returns.
