1.    Basis of Presentation
Nature of Business
Natural Resource Partners L.P. (the "Partnership") engages principally in the business of owning, managing and leasing a diversified portfolio of mineral properties in the United States, including interests in coal and other natural resources and owns a non-controlling 49% interest in Ciner Wyoming LLC ("Ciner Wyoming"), a trona ore mining and soda ash production business. The Partnership is organized into two2 operating segments further described in Note 6.5. 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.
Principles of Consolidation and Reporting
The accompanying unaudited consolidated financial statementsConsolidated Financial Statements of the Partnership have been prepared in accordance with generally accepted accounting principles in the United States of America ("GAAP") for interim financial information and with Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. These financial statements should be read in conjunction with the financial statements for the year ended December 31, 20182019 and notes thereto included in the Partnership's Annual Report on Form 10-K, which was filed with the SEC on March 7, 2019. In management's opinion, all necessary adjustments to fairly present the Partnership's results of operations, financial position and cash flows for the periods presented have been made and all such adjustments were of a normal and recurring nature. Certain reclassifications have been made to prior period amounts on the Consolidated Balance Sheets, Consolidated Statements of Comprehensive Income and Consolidated Statements of Cash Flows to conform with current period presentation. These reclassifications had no impact on previously reported total assets, total liabilities, partners' capital, net income or cash flows from operating, investing or financing activities.
Recasting of Certain Prior Period Information
As described in Note 3. Discontinued Operations, the Partnership reclassified prior period information for the assets and liabilities, operating results and cash flows of its construction aggregates business as discontinued operations in its consolidated financial statements for all periods presented.
Restricted Cash
Restricted cash at September 30, 2019 and December 31, 2018 represents the remaining net proceeds from the sale of the Partnership's construction aggregates business and other asset sales and disposals that is required to be used to repay debt, make acquisitions or make capital expenditures per the terms of the Partnership's and Opco's debt agreements. In the first nine months of 2019, the Partnership used $97.1 million of restricted cash to repay principal amounts on Opco's private placement senior notes (the "Opco Senior Notes") and it intends to use the remaining $12.5 million of restricted cash to repay a portion of the remaining principal payments on the Opco Senior Notes in 2019.February 27, 2020.
Recently Adopted Accounting Standards
LeasesCredit Losses
On January 1, 2019, NRP2020, the Partnership adopted Accounting Standards Codification (ASC) 842, Leases,ASU No. 2016-13, Financial Instruments—Credit Losses (Topic 326), and all the related amendments (the “new lease standard” and "ASC 842"("the new credit loss standard") and. The Partnership recognized assets and liabilities on its Consolidated Balance Sheet fora $3.9 million cumulative effect of adoption in the present valueopening balance of the rights and obligations created by all leases with terms of more than 12 months. This standard does not apply to leases that explore for or use minerals, oil, natural gas and similar non-regenerative resources, including the intangible right to explore for those natural resources and rights to use the land in which those natural resources are contained. The guidance also required disclosures designed to give financial statement users information on the amount, timing and uncertainty of cash flows arising from leases. The guidance was adopted by NRPpartners' capital on January 1, 2019 using2020 as a modified retrospective approach.
The Partnership is a lessee in one lease that is accounted for as an operating lease under the new lease standard, andresult of the adoption of the new lease standard did not have a material impact to the Partnership's consolidated financial statements.

agreements entered into or reassessed after the adoption of ASC 842, the Partnership elected to not combine lease and non-lease components. See Note 17. Leases for more information.
Recently Issued Accounting Standards
Credit Losses
In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments—Credit Losses (Topic 326). The new standard changes how entities will measure credit losses for most financial assets and certain other instruments that are not measured at fair value through net income. The new standard replaces today's "incurred loss" model with an "expected credit loss" model that requires entities to estimate an expected lifetime credit loss on financial assets, including trade accounts receivable. The guidance is effective for annual and interim periods beginning after December 15, 2019 and is to be adopted using a modified retrospective approach. The Partnership is continuing to evaluate the provisions of this guidance on its consolidated financial statements, but based on its analysis to date, the Partnership does not expect this standard to have a material effect on its consolidated financial statements.

3.    Discontinued Operations
In December 2018, the Partnership sold VantaCore Partners LLC, its construction aggregates business,annual fixed consideration owed to NRP in 2020 and in July 2016, the Partnership sold its non-operated oil and gas working interest assets. The Partnership's exit2021 resulting from both its construction aggregates business and non-operated oil and gas working interest business represented strategic shifts to reduce debt and focus on its Coal Royalty and Other and Soda Ash business segments. As a result, the Partnership classified the assets and liabilities, operating results and cash flows of these businesses as discontinued operations in its Consolidated Balance Sheets, Consolidated Statements of Comprehensive Income and Consolidated Statements of Cash Flows for all periods presented.

3.    Common and Preferred Unit Distributions
The Partnership makes cash distributions to common and preferred unitholders on a quarterly basis, subject to approval by the Board of Directors of GP Natural Resource Partners LLC (the "Board of Directors"). NRP recognizes both common unit and preferred unit distributions on the date the distribution is declared.
Distributions made on the common units and the general partner's general partner ("GP") interest are made on a pro-rata basis in accordance with their relative percentage interests in the Partnership. The general partner is entitled to receive 2% of such distributions.


Income (loss) available to common unitholders and the general partner is reduced by preferred unit distributions that accumulated during the period. NRP reduced net income attributable(loss) available to common unitholders and the general partner by $7.5 million during the three months ended September 30, 2020 and 2019, and 2018$22.6 million and $22.5 million during the nine months ended September 30, 2020 and 2019, and 2018respectively, as a result of accumulated preferred unit distributions earned during the period. DuringIn May 2020, the Partnership paid in kind one-half of the preferred unit distribution related to the three months ended March 31, 2018,2020. In June 2020, the Partnership redeemed all of the outstanding PIK Units, which resultedpreferred units paid in an $8.8 million cash payment during the period.

4.    Net Income (Loss) Per Common Unit
Basic net income (loss) per common unit is computed by dividing net income (loss), after considering income attributable to non-controlling interest, preferred unitholders and the general partner’s general partner interest, by the weighted average number of common units outstanding. Diluted net income (loss) per common unit includes the effect of NRP's preferred units, warrants, and unvested unit-based awards if the inclusion of these items is dilutive.
The dilutive effect of the preferred units is calculated using the if-converted method. Under the if-converted method, the preferred units are assumed to be converted at the beginning of the period, and the resulting common units are included in the denominator of the diluted net income (loss) per unit calculation for the period being presented. Distributions declared in the period and undeclared distributions on the preferred units that accumulated during the period are added back to the numerator for purposes of the if-converted calculation. The calculation of diluted net income (loss) per common unit for the three and nine months ended September 30, 2020 does not include the assumed conversion of the preferred units because the impact would have been anti-dilutive. The calculation of diluted net income per common unit for the three and nine months ended September 30, 2019 includes the assumed conversion of the preferred units.
The dilutive effect of the warrants is calculated using the treasury stock method, which assumes that the proceeds from the exercise of these instruments are used to purchase common units at the average market price for the period. The calculation of diluted net income (loss) per common unit for the three and nine months ended September 30, 2020 did not include the net settlement of warrants to purchase 1.75 million common units at a strike price of $22.81 or the net settlement of warrants to purchase 2.25 million common units with a strike price of $34.00 because the impact would have been anti-dilutive. The calculation of the dilutive effect of the warrants for the three months ended September 30, 2019 and 2018 and the nine months ended September 30, 2018 includes the net settlement of warrants to purchase 1.75 million common units with a strike price of $22.81 but did not include the net settlement of warrants to purchase 2.25 million common units with a strike price of $34.00 because the impact would have been anti-dilutive. The calculation of diluted net income per common unitthe dilutive effect of the warrants for the nine months ended September 30, 2019 includes both the net settlement of warrants to purchase 1.75 million common units atwith a strike price of $22.81 and the net settlement of warrants to purchase 2.25 million common units with a strike price of $34.00.

12.    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 ordinary course matters will not have a material effect on the Partnership’s financial position, liquidity or operations. During the third quarter, NRP was also involved in the matters described below.
Anadarko Contingent Consideration Payment Dispute
In January 2013, NRP acquired a non-controlling 48.51% general partner interest in OCI Wyoming, L.P. ("OCI LP") and all of the preferred stock and a portion of the common stock of OCI Wyoming Co. ("OCI Co") (which in turn owned a 1% limited partner interest in OCI LP) from Anadarko Holding Company and its subsidiary, Big Island Trona Company (together, "Anadarko").  The remaining general partner interest in OCI LP and common stock of OCI Co were owned by subsidiaries of OCI Chemical Corporation.
The acquisition agreement provided for additional contingent consideration of up to $50 million to be paid by NRP if certain performance criteria were met at OCI LP as defined in the purchase and sale agreement in any of the years 2013, 2014 or 2015. For those years, NRP paid an aggregate of $11.5 million to Anadarko in full satisfaction of these contingent consideration payment obligations.
  In July 2013, pursuant to a series of transactions in connection with an initial public offering by a subsidiary of OCI Chemical Corporation, the ownership structure in OCI LP was simplified. In connection with such reorganization, NRP exchanged the stock of OCI Co for a limited partner interest in OCI LP. Following the reorganization, NRP's interest in OCI LP remained at 49%, consisting of both limited and general partner interests. The restructuring did not have any impact on the operations, revenues, management or control of OCI LP.
In July 2017, Anadarko filed a lawsuit against Opco and NRP Trona LLC in the District Court of Harris County, Texas, 157th judicial district. The complaint alleged that the transactions conducted in 2013 triggered an acceleration of NRP's obligation under the purchase agreement with Anadarko to pay additional contingent consideration in full and demanded immediate payment of such amount, together with interest, court costs and attorneys’ fees. NRP does not believe the reorganization transactions triggered an obligation to pay any additional contingent consideration and is vigorously defending this lawsuit. However, the ultimate outcome cannot be predicted with certainty and the Partnership estimates a possible range of loss between $0, if it prevails, and approximately $40 million plus interest, court costs and attorneys’ fees if Anadarko prevails and is awarded the full damages it seeks. A trial in this matter was held in October 2019. The parties are currently awaiting a ruling by the trial court.

NRP assessed the likelihood of collection of its receivables utilizing historical loss rates, current market conditions that included the estimated impact of the global COVID-19 pandemic, industry and macroeconomic factors, reasonable and supportable forecasts and facts or circumstances of individual customers and properties. Examples of these facts or circumstances include, but are not limited to, contract disputes or renegotiations with the customer and evaluation of short and long-term economic viability of the contracted property. For its long-term contract receivable, management reverts to the historical loss experience immediately after the reasonable and supportable forecast period ends.

As of September 30, 2020, NRP recorded the following current expected credit loss (“CECL”) related to its receivables and long-term contract receivable:

Current Results/Market Commentary
Business Outlook and Quarterly Distributions
The global COVID-19 pandemic has had a significant negative impact on demand for steel, electricity and glass, which translates to lower demand for the coal and soda ash that our properties produce. While demand for metallurgical and thermal coals and soda ash began to rebound during the third quarter, prices remain below pre-pandemic levels. We continue to employ remote work protocols and are conducting business as usual despite the pandemic. Although we are unable to predict the ultimate severity or duration of the COVID-19 pandemic or its impact on our business, we ended the third quarter with $215.6 million of liquidity consisting of $115.6 million of cash and cash equivalents and $100.0 million of borrowing capacity under our Opco Credit Facility and generated $74.9 million of free cash flow during the nine months ended September 30, 2020. As a result, we believe we have the financial flexibility to navigate the effects of the pandemic on our business.
Despite our liquidity level at the end of the third quarter, our consolidated leverage ratio has risen since the onset of the COVID-19 pandemic and was 4.2x at September 30, 2020. The indenture governing our 2025 parent company notes restricts us from paying more than one-half of the quarterly distribution on our preferred units in cash if our consolidated leverage ratio exceeds 3.75x. Accordingly, the Board of Directors of our general partner declared a distribution on our preferred units for the third quarter of 2020 to be paid one-half in cash equal to $3.75 million and one-half in kind through the issuance of 3,750 additional preferred units. The Board also declared a cash distribution of $0.45 per common unit for the third quarter of 2020. To the extent our leverage ratio continues to exceed 3.75x, which we expect for the foreseeable future, we will be required to continue to pay one-half of the required preferred distributions in kind (“PIK units”) and will be unable to redeem any PIK units until our consolidated leverage ratio falls below 3.75x. Distributions on the outstanding PIK units will accrue and accumulate at 12% per year until such PIK units are redeemed.

Future distributions on NRP's common and preferred units will be determined on a quarterly basis by the Board of Directors. The Board of Directors considers numerous factors each quarter in determining cash distributions, including profitability, cash flow, debt service obligations, market conditions and outlook, estimated unitholder income tax liability and the level of cash reserves that the Board determines is necessary for future operating and capital needs.

Coal Royalty and Other Business Segment

Demand for steel and electricity began to rebound in the third quarter and the outlook for our coal businesses has improved, though sales volumes and prices for coal sold from our properties in the third quarter remained below pre-pandemic levels. We expect coal markets to remain volatile as a result of ongoing uncertainties with the COVID-19 pandemic.

Our resultslessees sold 12.1 million tons of coal from our properties in the first nine months of 2019 were driven by stability in both metallurgical2020 and thermal coal realizations from our lessees during the first half of the year but reduced realizations during the third quarter driven by weakened market demand and lower activity at certain of our properties. Wewe derived approximately 65%70% of our coal royalty revenues and approximately 55%65% of our coal royalty sales volumes from metallurgical coal during the nine months ended September 30, 2019. Despite solid performance throughsame period. Revenues and other income in the first nine months of 2019, declining coal prices and lessee bankruptcies are expected2020 were lower by $79.4 million as compared to put downward pressure on our performance in the coming months.

Theprior year period. This decrease is primarily a result of a weakened market for metallurgical coal weakened primarilyas compared to the prior year period due to a decline in global economic growth.steel demand. As a result, both sales volumes and prices for metallurgical coal sold were lower in the first nine months of 2020 compared to the prior year period. Prices for metallurgical coal have rebounded from the lows seen in the second quarter, but are not currently above pre-pandemic levels.

In addition, weaker domestic and export thermal coal markets compared to the prior year period resulted in lower revenues from our properties declined in the third quarter of 2019. Metallurgical coal sales volumes from our properties also declined in the third quarter of 2019 as a result of certain lessees moving off our coal reserves in the normal course of their mine plans and lower activity at certain other mines.

The domestic market for thermal coal remainsproperties. Domestic and export thermal coal markets remained challenged by lower utility demand, continued low natural gas prices and growing stockpilesthe secular shift to renewable energy. Although natural gas prices are forecasted to rise above $3/MMBtu this winter, stockpile levels at domestic utilities. In addition,utilities remain high, which we expect will temper the export market forincreased thermal coal demand that would normally result from higher natural gas prices. Our thermal coal business results are largely dependent on our various lease agreements with Foresight Energy. In June 2020, we entered into lease amendments with Foresight Energy pursuant to which Foresight agreed to pay us fixed cash payments of $48.75 million in 2020 and $42.0 million in 2021 to satisfy all obligations arising out of the existing various coal mining leases and transportation infrastructure fee agreements between us and Foresight Energy for calendar years 2020 and 2021. These amendments provide us cash flow certainty for our thermal coal business through 2021. Through the first nine months of 2020, we received $35.0 million of the $48.75 million due to us in 2020.

Soda Ash Business Segment
Ciner Wyoming has weakenedbeen negatively impacted by the COVID-19 pandemic as lower activity in the global auto, container and construction industries reduced demand for glass and soda ash. Revenues and other income in the third quarter of 2020 were lower by $11.8 million compared to the prior year quarter primarily due to a combination of lower pricing and volumes sold. However, demand from European utilities, competition from international producers and oversupply of LNG.

We remain cautious aboutfor glass began to rebound in the financial position of U.S. coal producers with over-leveraged capital structuresthird quarter and the stateoutlook for our soda ash business has improved. While Ciner Wyoming has yet to recover to pre-COVID levels, overall sales volumes increased 26.7% and overall production volumes increased 1.5% over second quarter 2020 results, though global prices remain depressed. While we believe our facility is competitively positioned as one of the domestic and global coal markets generally. The current price environment along with limited access to capital has taken a toll on a numberlowest cost producers of producers. Four of our lessees have filed for protection under the U.S. Bankruptcy Code in the last six months, and other lessees continue to face challenges. Foresight Energy, which is our largest lessee, has agreed to a forbearance period with its lenders to evaluate their restructuring options. To the extent Foresight determines to idle operations on our properties for a prolonged period or to shut any of its mines on our properties down permanently, our business could be adversely affected. Accordingly, we remain focused on further strengthening our liquidity and balance sheet.

Soda Ash Business Segment

Ciner Wyoming's results are primarily affected by the global supply of and demand for soda ash, which in turn directly impacts the prices Ciner Wyoming and other producers charge for its products. Demand for soda ash in the United States is driven in a large part by economic growth and activity levels in the end markets that the glass-making industry serve, such as the automotive and construction industries. Because the United States is a well-developed market for soda ash,world, we expect that domestic supplythe market to remain volatile as a result of ongoing uncertainties with the COVID-19 pandemic.

In order to have financial flexibility during the COVID-19 pandemic, Ciner Wyoming suspended its quarterly distribution in August 2020 and demand for soda ash will remain stableaccordingly, did not pay quarterly distributions for the near future. Soda ash demand in international markets has continued to grow in conjunction with GDP. We expect that future global economic growth will positively influence global demand and pricing, which will likely result in increased exports, primarily from the United States, Turkey and to a limited extent, from China, the largest supplierssecond or third quarters of soda ash to international markets.

While the performance of the underlying business remains stable,2020. Ciner Wyoming has announced that it will commencecontinue to evaluate, on a quarterly basis, whether to reinstate the distribution. Ciner Wyoming’s ability to pay future quarterly distributions will be dependent in part on its cash reserves, liquidity, total debt levels and anticipated capital expenditures. In addition, Ciner Wyoming continues to develop plans for a significant capacity expansion capital project. However, they have delayed the timing of significant costs related to this project soon that it intends to fund in part by reinvesting cash that would otherwise be distributed to its partners. As a result, we expect foruntil they have more visibility into the cash distributions we receive from Ciner Wyoming to decrease to approximately $25 million to $28 million per year and be held at such levels for the next two to three years. We believe that we will benefit over the long-term from increased productivity and cash distributions from Ciner Wyoming’s operations following completion of this capital project.

Business Outlook

Despite solid performance in the first nine monthsimpact of the year, we expect the challenges described above to have an overall adverse impactCOVID-19 pandemic on our future results as compared to recent results. However, we believe the progress made to strengthen our financial profile in recent years positions us well to navigate a sustained downturn.their business

Coal Royalty Revenues
Approximately 70% of coal royalty revenues and approximately 65% of coal royalty sales volumes were derived from metallurgical coal during the three months ended September 30, 2020. Coal royalty revenues decreased $6.0$14.1 million period-over-period primarily driven by the weakened coal markets that resulted in lower coal sales volumes.volumes and prices. The discussion of these decreases by region is as follows:
Appalachia: Sales volumes decreased 14%36% and coal royalty revenues decreased $4.3$10.6 million primarily as a result ofdue to weakened coal markets,demand compounded by the temporary COVID-19 pandemic.
Illinois Basin: Sales volumes increased 38% due to increased activity at the Hillsboro and Williamson mines, while coal royalty revenues decreased $1.4 million primarily due to the idling of our Macoupin property. As mentioned above, certain propertiesrevenues previously classified as coal royalty revenues are classified as production lease minimum revenues or minimum lease straight-line revenues due to lessee bankruptcies and the idling of the Pinnacle mine since the fourth quarter of 2018.
contract modifications with Foresight Energy that fixed consideration paid to us over a two-year period.
IllinoisNorthern Powder River Basin: Sales volumes decreased 10%31% and coal royalty revenues decreased $0.3 million primarily due to reduced demand for Illinois Basin coal.
Northern Powder River Basin: Sales volumes decreased 38% and coal royalty revenues decreased $0.7$1.2 million primarily due to our lessee mining off of our property in accordance with its mine plan in 2019.
Other Revenues
Total other revenues increased $3.4 million primarily due to $3.4 million of increased minimum lease straight-line revenues primarily related to our Hillsboro property that we began to recognize in 2019 after the completion of the Hillsboro litigation settlement with Foresight and $1.5 million of increased lease amendment revenues during the third quarter of 2019. These increases were partially offset by lower coal overriding royalty revenues due to reduced sales volumes and lower oil and gas royalty revenues driven by lower natural gas prices during the third quarter of 2019 compared to the prior year quarter.2020.
Transportation and Processing Services Revenues
Transportation and processing services revenues decreased $3.0$1.7 million primarily due to weakened demand for Illinois Basin coal that resulted in fewer tons being transported outidling of our Illinois Basinthe Macoupin mine where we own loadout and other transportation and processing assets during the third quarter of 2019.assets.
Gain on Asset Sales and Disposals
Gain on asset sales and disposals increaseddecreased $6.1 million primarily due to the disposal of certain mineral right assets during the third quarter of 2019.
Soda Ash

Revenues and other income related to our Soda Ash segment increased $5.0decreased $11.8 million primarily due to an increasea combination of lower pricing and volumes sold. Ciner Wyoming was negatively impacted by the COVID-19 pandemic as lower activity in productionthe global auto, container and sales volumesconstruction industries reduced demand for glass and increased domesticsoda ash.

DCF and FCF increased $20.1decreased $23.5 million and $14.1$17.5 million, respectively, primarily due to the following:
Coal Royalty and Other Segment
DCF increased $4.5 million primarily as a result of the proceeds received for the disposal of certain assets and the collection of the Hillsboro minimum payment in the third quarter of 2019, partially offset by lower coal royalty revenues as described above.
FCF decreased $1.6 million primarily due to lower coal royalty revenues in the third quarter of 2019 as compared to the same period in 2018, partially offset by collection of the Hillsboro minimum payment in the third quarter of 2019.
DCF and FCF decreased $18.8 million and $12.6 million, respectively, primarily as a result of the weakened coal markets in the third quarter of 2020. DCF was also impacted by $6.1 million in asset sale proceeds received in the third quarter of 2019.
Soda Ash Segment
DCF and FCF decreased $6.1 million as a result of lower cash distributions received from Ciner Wyoming in the third quarter of 2019.
Corporate and Financing Segment
DCF and FCF increased $21.9 million primarily due to lower cash paid for interest as a result of the timing of interest payments on our 2022 Senior Notes in 2018 as compared to the timing of interest payments on our 2025 Senior Notes in 2019 and due to lower interest payments on our Opco Senior Notes as a result of lower principal balances during the third quarter of 2019.

FCF decreased $6.2 million as a result of the suspended cash distribution from Ciner Wyoming in the third quarter of 2020 as compared to the $6.4 million distribution received during the third quarter of 2019.

Coal Royalty Revenues
CoalTotal coal royalty revenues decreased $8.9$47.0 million year-over-year.from 2019 to 2020 primarily driven by weakened coal markets that resulted in lower coal sales volumes and pricing. The discussion of these decreases by region is as follows:
Appalachia: Sales volumes were flat year-over year whiledecreased 38% and revenues decreased $4.2$37.3 million or 5%. Northern Appalachia includes our Hibbs Run property that has significant sales volumes but a low fixed royalty rate per ton and as a result has a minimal impact on our revenues. Excluding Hibbs Run, sales volumes from our Appalachia properties decreased approximately 8% primarily as a result of due to weakened coal markets,demand compounded by the temporary idling of certain properties COVID-19 pandemic.
Illinois Basin: Sales volumes increased 12% due to lessee bankruptciesincreased activity at the Hillsboro and Williamson mines, while coal royalty revenues decreased $3.2 million primarily due to the idling of the Pinnacle mine since the fourth quarter of 2018.
our Macoupin property. As mentioned above, certain revenues previously classified as coal royalty revenues are classified as production lease minimum revenues or minimum lease straight-line revenues due to contract modifications with Foresight Energy that fixed consideration paid to us over a two-year period.
IllinoisNorthern Powder River Basin: Sales volumes decreased 21%38% and coal royalty revenues decreased $1.8 million primarily due to flooding and high water throughout the river systems that affected transportation logistics during the first half of 2019, including at the Convent Marine Terminal on the Gulf of Mexico, in addition to a weakening of the thermal export market and lower domestic thermal coal demand in 2019.
Northern Powder River Basin: Sales volumes decreased 32% and coal royalty revenues decreased $1.5 million primarily due to our lessee mining off of our property in accordance with its mine plan in 2019.
2020, partially offset by a 14% increase in sales prices as compared to the prior year.
Other Revenues
Total otherOther revenues increased $28.0decreased $18.2 million primarily due to:to the following:
$15.0A $7.8 million increaseddecrease in production lease minimum revenues primarily as a result of increasedthe Macoupin lease amendment and lessee forfeitures of recoupable balances in the second quarter of 2019 from minimums paid in prior periods.periods;
$9.4A $6.8 million increased minimum lease straight-line revenues primarily related to our Hillsboro property that we began to recognizedecrease in 2019 after the completion of the Hillsboro litigation settlement with Foresight.
$6.7 million of lease amendment revenues during the nine months ended September 30, 2019.
These increases in other revenues were partially offset by $3.1 million of lower oil and gascoal overriding royalty revenues during the nine months ended September 30, 2019revenues primarily as a result of lower natural gas pricesproduction at the Williamson mine moving off NRP's overriding royalty interest and back onto NRP's coal reserves. As a result, this decrease in coal overriding royalty revenues was offset by an increase in coal royalty revenues.
A $4.1 million decrease in lease amendment revenues year-over-year.
Transportation and Processing Services Revenues
Transportation and processing services revenues decreased $2.5$8.1 million primarily due to weakened demand for Illinois Basin coal that resulted in fewer tons being transported outidling of our Illinois Basinthe Macoupin mine where we own loadout and other transportation and processing assets during the nine months ended September 30, 2019.assets.
Gain on Asset Sales and Disposals
Gain on asset sales and disposals increased $5.8decreased $6.1 million primarily due to the disposal of certain mineral right assets during the third quarter of 2019.
Soda Ash


Revenues and other income related to our Soda Ash segment increased $1.8decreased $31.6 million primarily due to an increase in production and sales volumes and increased domestic and international sales prices in the nine months ended September 30, 2019 compared to the prior year period, partially offsetprimarily due to a combination of lower pricing and volumes sold. Ciner Wyoming was negatively impacted by Ciner Wyoming's settlement of a royalty disputethe COVID-19 pandemic as lower activity in the second quarter of 2018 that resulted in $12.7 million of income in the prior year period.global auto, container and construction industries reduced demand for glass and soda ash.

Total operating expenses increased $4.3$117.9 million primarily due to the following:
Asset impairments increased $132.7 million due to weakened coal markets that resulted in termination of certain coal leases, changes to lessee mine plans resulting in permanent moves off certain of our coal properties and decreased oil and gas drilling activity which negatively impacted the outlook for NRP's frac sand properties.
This increase in operating expense was partially offset by:
Operating and maintenance expenses increased $5.7include costs to manage the Coal Royalty and Other and Soda Ash segments and primarily consist of royalty, tax, employee-related and legal costs and bad debt expense. These costs decreased $7.6 million primarily due to a decrease in bad debt expense recognized in the second quarter of 2019addition to lower royalty fees related to certain of our Coal Royalty and Other receivables, partiallyan overriding royalty agreement with Western Pocahontas Properties Limited Partnership ("WPPLP"). The coal royalty expense NRP pays to WPPLP is fully offset by lower legal costs.the coal royalty revenue NRP receives from this property.
Depreciation, depletion and amortization expense decreased $3.6$5.6 million primarily due to lower coal sales volumes at certain properties.
General and administrative expenses increased $2.0 million primarily due to increased legal and consulting costs.
Total other expenses, net increased $13.2decreased $35.5 million primarily due to the following:
Interest expense, net decreased $16.1 million primarily due to lower debt balances during the first nine months of 2019 as a result of debt repayments.
Loss on extinguishment of debt wasof $29.3 million for the nine months ended September 30,in 2019 and related to the 105.25% premium paid to redeem the 2022 Senior Notes in the second quarter of 2019 as well as the write-off of unamortized debt issuance costs and debt discount related to the 2022 Senior Notes.
Income from Discontinued Operations
Income from discontinued operationsInterest expense, net decreased $3.5$6.2 million primarily as a result of the sale of our construction aggregates business in the fourth quarter of 2018. This business generated $3.8 million of net income indue to lower debt balances during the first nine months of 2018.2020 as a result of debt repayments made over the past twelve months.

DCF and FCF increased $22.0decreased $49.0 million and $16.8$44.4 million, respectively, primarily due to the following:
Coal Royalty and Other Segment
DCF and FCF increased $12.2 million and $6.4 million, respectively, as a result of the collection of lease amendment fees and the Hillsboro minimum payments in the first nine months of 2019, partially offset by lower coal royalty revenues as described above. DCF also increased as a result of the proceeds received in the third quarter of 2019 related to the sale and disposal of certain assets.
DCF and FCF decreased $54.7 million and $49.6 million, respectively, primarily as a result of the weakened coal markets in the first nine months of 2020. DCF was also impacted by a $6.1 million decrease in asset sale proceeds compared to the third quarter of 2019.
Soda Ash Segment
DCF and FCF decreased $11.5 million as a result of lower cash distributions received from Ciner Wyoming in the first nine months of 2019.
DCF and FCF decreased $11.2 million as a result of lower cash distributions received from Ciner Wyoming in the first nine months of 2020.
Corporate and Financing Segment
DCF and FCF increased $21.8 million primarily due to lower cash paid for interest as a result of the timing of interest payments on our 2022 Senior Notes in 2018 as compared to the timing of interest payments on our 2025 Senior Notes in 2019 and lower interest paid on our Opco Senior Notes as a result of lower principal balances during the first nine months of 2019.


DCF and FCF increased $16.4 million primarily due to lower cash paid for interest as a result of less outstanding debt in the first nine months of 2020.

Liquidity and Capital Resources
Current Liquidity
As of September 30, 2019,2020, we had total liquidity of $212.2$215.6 million, consisting of $99.6$115.6 million of cash and cash equivalents $12.5 million of restricted cash and $100.0 million of borrowing capacity under theour Opco Credit Facility. The $12.5 million of restricted cash is required to be used to repay debt, make acquisitions or make capital expenditures per the terms of our debt agreements. We intend to use our restricted cash to repay a portion of the remaining principal payments on our Opco Senior Notes in 2019.
Cash Flows
Cash flows provided by operating activities increased $10.4decreased $41.8 million, from $107.5 million in the nine months ended September 30, 2018 to $117.9 million in the nine months ended September 30, 2019 to $76.1 million in the nine months ended September 30, 2020 primarily related to the timing of interest payments on our 2022 Senior Notes in 2018 as compared to the timing of interest payments on our 2025 Senior Notes in 2019, lower operating cash paid for interest on our Opco Senior Notesflow as a result of lower debt balances during the first nine months of 2019, and the collection of lease amendment fees and the Hillsboro minimum payment within our Coal Royalty and Other segment. These increases were partially offset byweakened coal markets in addition to lower cash distributions received from Ciner Wyoming lower coal royalty revenues drivenin the first nine months of 2020, partially offset by weakened coal markets,less cash paid for interest in the temporary idlingfirst nine months of certain properties2020 due to lessee bankruptcies and the idling of the Pinnacle mine since the fourth quarter of 2018, and lower cash provided by operating activities of discontinued operations as a result of the sale of our construction aggregates business in the fourth quarter of 2018.less debt outstanding.
Cash flows provided by investing activities increased $11.2decreased $6.5 million, from $3.8 million used in the nine months ended September 30, 2018 to $7.4 million provided in the nine months ended September 30, 2019 primarily due to $9.7 million of capital expenditures made by our discontinued operation in the first nine months of 2018 and a $5.8 million increase in proceeds from asset sales and disposals year-over-year. These increases were partially offset by a portion of our distribution from Ciner Wyoming being classified as an investing activity in the nine months ended September 30, 2018.
Cash flows used in financing activities increased $149.0 million, from $70.2$0.9 million in the nine months ended September 30, 20182020 primarily due to a $6.1 million decrease in asset sale proceeds compared to the third quarter of 2019.
Cash flows used in financing activities decreased $159.5 million, from $219.2 million in the nine months ended September 30, 2019. In2019 to $59.7 million in the second quarter of 2019, we extended the maturity date of the $100.0 million Opco Credit Facilitynine months ended September 30, 2020 primarily due to April 2023 and issued $300 million of a new series of 9.125% senior notes due 2025. We used the net proceeds from this offering, together with $76 million of cash on hand to redeem all of our 2022 Senior Notes. As a result of these transactions, our outstanding debt was reduced, our annual interest expense has decreased, and our debt maturities were extended. Significant increases in cash flow used in financing activities included the following:
$345.6 million used for the redemption of our 2022 Senior Notes in the second quarter of 2019;
$41.4The $49.3 million increasepre-payment in payments on the Opco Senior Notes primarily as a resultfirst quarter of the prepayment made using proceeds from2019 related to the sale of our construction aggregates business;
$35.026.4 million less borrowings on our Opco Credit Facilityin debt issuance costs and other in 2019 primarily related to 2019 debt refinancings; and
$16.1 million in lower cash distributions in the first nine months of 2019 compared to the prior year period;
$26.2 million increase in debt issuance costs and other primarily related to the 2019 debt refinancings; and

Summary of Critical Accounting Estimates
The preparation of consolidated financial statements in conformity with generally accepted accounting principles in the United States of America requires management to make certain estimates and assumptions that affect the amounts reported in the consolidated financial statementsConsolidated Financial Statements and the accompanying notes. There have been no significant changes to our critical accounting estimates from those disclosed in our Annual Report on Form 10-K for the year ended December 31, 2018.2019.
Recent Accounting Standards
The information set forth under Note 1. Basis of Presentation to the consolidated financial statementsConsolidated Financial Statements is incorporated herein by reference.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
We are exposed to market risk, which includes adverse changes in commodity prices and interest rates as discussed below:
Commodity Price Risk
Our revenues, operating results, financial condition and ability to borrow funds or obtain additional capital depend substantially on prevailing commodity prices. Historically, coal prices have been volatile, with prices fluctuating widely, and they are likely to continue to be volatile. Depressed prices in the future would have a negative impact on our future financial results. In particular, substantially lower prices would significantly reduce revenues and could potentially trigger an impairment of our coal properties or a violation of certain financial debt covenants. Because substantially all of our reserves are coal, changes in coal prices have a more significant impact on our financial results.
We are dependent upon the effective marketing of the coal mined by our lessees. Our lessees sell the coal under various long-term and short-term contracts as well as on the spot market. Current conditions in the coal industry may make it difficult for our lessees to extend existing contracts or enter into supply contracts with terms of one year or more. Our lessees’ failure to negotiate long-term contracts could adversely affect the stability and profitability of our lessees’ operations and adversely affect our future financial results. If more coal is sold on the spot market, coal royalty revenues may become more volatile due to fluctuations in spot coal prices.

The market price of soda ash and energy costs directly affects the profitability of Ciner Wyoming’s operations. If the market price for soda ash declines, Ciner Wyoming’s sales revenues will decrease. Historically, the global market and, to a lesser extent, the domestic market for soda ash have been volatile and are likely to remain volatile in the future.
The uncertainty that exists with respect to the economic impact of the global COVID-19 pandemic has introduced significant volatility in the financial markets subsequent to our quarter ended September 30, 2020. The impacts of such volatility on the Partnership cannot be predicted with confidence or reasonably estimated at this time.

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 September 30, 2019,2020, we did not have any borrowings outstanding under the Opco Credit Facility.
