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.

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

Income available to common unitholders and the general partner is reduced by preferred unit distributions that accumulated during the period. NRP reduced net income available to common unitholders and the general partner by $7.7 million and $7.5 million during the three months ended March 31, 2021 and 2020, respectively, as a result of accumulated preferred unit distributions earned during the period. In February 2021, the Partnership paid in kind one-half of the preferred unit distribution related to the three months ended December 31, 2020, which resulted in the issuance of an additional 3,806 preferred units during the three months ended March 31, 2021.

The following table shows the cash distributions declared and paid to common and preferred unitholders during the three months ended March 31, 2021 and 2020, respectively:
Common UnitsPreferred Units
Date PaidPeriod Covered by DistributionDistribution per Unit

2020
February 2020October 1 - December 31, 2019$0.45 $5,630 $30.00 $7,500 
(1)Totals include the amount paid to NRP's general partner in accordance with the general partner's 2% general partner interest.

4.    Net Income Per Common Unit
Basic net income per common unit is computed by dividing net income, after considering income attributable to preferred unitholders and the general partner’s general partner interest, by the weighted average number of common units outstanding. Diluted net income per common unit includes the effect of NRP's preferred units, 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 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 per common unit for the three months ended March 31, 2021 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 months ended March 31, 2020 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 per common unit for the three months ended March 31, 2021 and 2020 does 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.

Depletion expense related to the Partnership’s mineral rights is included in depreciation, depletion and amortization on its Consolidated Statements of Comprehensive Income and totaled $4.7 million and $1.9 million for the three months ended March 31, 2021 and 2020, respectively.

During the three months ended March 31, 2021, the Partnership recorded $4.0 million of impairment expense primarily due to lease termination that resulted in the full impairment of a coal property. The Partnership has developed procedures to evaluate its long-lived assets for possible impairment periodically or whenever events or changes in circumstances indicate an asset's net book value may not be recoverable. Potential events or circumstances include, but are not limited to, specific events such as a reduction in economically recoverable reserves or production ceasing on a property for an extended period. This analysis is based on historic, current and future performance and considers both quantitative and qualitative information. While the Partnership's impairment evaluation as of March 31, 2021 incorporated an estimated impact of the global COVID-19 pandemic, there is significant uncertainty as to the severity and duration of this disruption. If the impact is worse than we currently estimate, an additional impairment charge may be recognized in future periods.

2025 Senior Notes
The 2025 Senior Notes were issued under an Indenture dated as of April 29, 2019 (the "2025 Indenture"), bear interest at 9.125% per year and mature on June 30, 2025. Interest is payable semi-annually on June 30 and December 30.
NRP and NRP Finance have the option to redeem the 2025 Senior Notes, in whole or in part, at any time on or after October 30, 2021, at the redemption prices (expressed as percentages of principal amount) of 104.563% for the 12-month period beginning October 30, 2021, 102.281% for the 12-month period beginning October 30, 2022, and thereafter at 100.000%, together, in each case, with any accrued and unpaid interest to the date of redemption. Furthermore, before October 30, 2021, NRP may on any one or more occasions redeem up to 35% of the aggregate principal amount of the 2025 Senior Notes with the net proceeds of certain public or private equity offerings at a redemption price of 109.125% of the principal amount of 2025 Senior Notes, plus any accrued and unpaid interest, if any, to the date of redemption, if at least 65% of the aggregate principal amount of the 2025 Senior Notes issued under the 2025 Indenture remains outstanding immediately after such redemption and the redemption occurs within 180 days of the closing date of such equity offering. In the event of a change of control, as defined in the 2025 Indenture, the holders of the 2025 Senior Notes may require us to purchase their 2025 Senior Notes at a purchase price equal to 101% of the principal amount of the 2025 Senior Notes, plus accrued and unpaid interest, if any. The 2025 Senior Notes were issued at par.

The 2025 Senior Notes are the senior unsecured obligations of NRP and NRP Finance. The 2025 Senior Notes rank equal in right of payment to all existing and future senior unsecured debt of NRP and NRP Finance and senior in right of payment to any of NRP's subordinated debt. The 2025 Senior Notes are effectively subordinated in right of payment to all future secured debt of NRP and NRP Finance to the extent of the value of the collateral securing such indebtedness and are structurally subordinated in right of payment to all existing and future debt and other liabilities of our subsidiaries, including the Opco Credit Facility and each series of Opco’s existing senior notes. None of NRP's subsidiaries guarantee the 2025 Senior Notes. As of March 31, 2021 and December 31, 2020, NRP and NRP Finance were in compliance with the terms of the Indenture relating to their 2025 Senior Notes.
Opco Debt
All of Opco’s debt is guaranteed by its wholly owned subsidiaries and is secured by certain of the assets of Opco and its wholly owned subsidiaries, other than BRP LLC and NRP Trona LLC. As of March 31, 2021 and December 31, 2020, Opco was in compliance with the terms of the financial covenants contained in its debt agreements.
Opco Credit Facility
In April 2019, the Partnership entered into the Fourth Amendment (the “Fourth Amendment”) to the Opco Credit Facility (the "Opco Credit Facility"). The Fourth Amendment extended the term of the Opco Credit Facility until April 2023. Lender commitments under the Opco Credit Facility remain at $100.0 million. The Opco Credit Facility contains financial covenants requiring Opco to maintain:
A leverage ratio of consolidated indebtedness to EBITDDA (as defined in the Opco Credit Facility) not to exceed 4.0x; provided, however, that if the Partnership increases its quarterly distribution to its common unitholders above $0.45 per common unit, the maximum leverage ratio under the Opco Credit Facility will permanently decrease from 4.0x to 3.0x; and
a fixed charge coverage ratio of consolidated EBITDDA to consolidated fixed charges (consisting of consolidated interest expense and consolidated lease expense) of not less than 3.5 to 1.0.
During the three months ended March 31, 2021 and 2020, the Partnership did not have any borrowings outstanding under the Opco Credit Facility and had $100.0 million in available borrowing capacity at both March 31, 2021 and December 31, 2020.
The Opco Credit Facility is collateralized and secured by liens on certain of Opco’s assets with carrying values of $360.3 million and $364.5 million classified as mineral rights, net and other long-term assets, net on the Partnership’s Consolidated Balance Sheets as of March 31, 2021 and December 31, 2020, respectively.
Opco Senior Notes   
Opco has issued several series of private placement senior notes (the "Opco Senior Notes") with various interest rates and principal due dates. As of March 31, 2021 and December 31, 2020, the Opco Senior Notes had cumulative principal balances of $161.2 million and $177.9 million, respectively. Opco made mandatory principal payments of $16.7 million during the three months ended March 31, 2021 and 2020.
The 8.92% Opco Senior Notes also provides that in the event that Opco’s leverage ratio of consolidated indebtedness to consolidated EBITDDA (as defined in the Note Purchase Agreements) exceeds 3.75 to 1.00 at the end of any fiscal quarter, then in addition to all other interest accruing on these notes, additional interest in the amount of 2.00% per annum shall accrue on the notes for the two succeeding quarters and for as long thereafter as the leverage ratio remains above 3.75 to 1.00. Opco has not exceeded the 3.75 to 1.00 ratio at the end of any fiscal quarter through March 31, 2021.

9.    Fair Value Measurements
Fair Value of Financial Assets and Liabilities
The Partnership’s financial assets and liabilities consist of cash and cash equivalents, a contract receivable and debt. The carrying amounts reported on the Consolidated Balance Sheets for cash and cash equivalents approximate fair value due to their short-term nature. The Partnership uses available market data and valuation methodologies to estimate the fair value of its debt and contract receivable.
The following table shows the carrying value and estimated fair value of the Partnership's debt and contract receivable:

(2)The fair value of the Partnership's contract receivable is determined based on the present value of future cash flow projections related to the underlying asset at a discount rate of 15% at March 31, 2021 and December 31, 2020.
NRP has embedded derivatives in the preferred units related to certain conversion options, redemption features and the change of control provision that are accounted for separately from the preferred units as assets and liabilities at fair value on the Partnership's Consolidated Balance Sheets. Level 3 valuation of the embedded derivatives are based on numerous factors including the likelihood of the event occurring. The embedded derivatives are revalued quarterly and changes in their fair value would be recorded in other expenses, net on the Partnership's Consolidated Statements of Comprehensive Income. The embedded derivatives had zero value as of March 31, 2021 and December 31, 2020.

10.    Related Party Transactions
Affiliates of our General Partner
The Partnership’s general partner does not receive any management fee or other compensation for its management of NRP.

14.    Financing Transaction
The Partnership owns rail loadout and associated infrastructure at the Sugar Camp mine in the Illinois Basin operated by a subsidiary of Foresight Energy. The infrastructure at the Sugar Camp mine is leased to a subsidiary of Foresight Energy and is accounted for as a financing transaction (the "Sugar Camp lease"). The Sugar Camp lease expires in 2032 with renewal options for up to 80 additional years. Minimum payments are $5.0 million per year through the end of the lease term. The $5.0 million due to the Partnership in 2021 is included in the fixed cash payments from Foresight resulting from contract modifications entered into during the second quarter of 2020 as discussed in Note 11. Major Customers. The Partnership is also entitled to variable payments in the form of throughput fees determined based on the amount of coal transported and processed utilizing the Partnership's assets. In the event the Sugar Camp lease is renewed beyond 2032, payments become a fixed $10 thousand per year for the remainder of the renewed term.

15.    Credit Losses
The Partnership is exposed to credit losses through collection of its short-term trade receivables resulting from contracts with customers and a long-term receivable resulting from a financing transaction with a customer. The Partnership records an allowance for current expected credit losses on these receivables based on the loss-rate method. 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 March 31, 2021 and December 31, 2020, NRP had the following current expected credit loss (“CECL”) allowance related to its receivables and long-term contract receivable:

NRP recorded $0.4 million and $(0.4) million in operating and maintenance expenses on its Consolidated Statements of Comprehensive Income related to the change in the CECL allowance during the three months ended March 31, 2021 and 2020, respectively.

NRP has procedures in place to monitor its ongoing credit exposure through timely review of counterparty balances against contract terms and due dates, account and financing receivable reconciliation, bankruptcy monitoring, lessee audits and dispute resolution. The Partnership may employ legal counsel or collection specialist to pursue recovery of defaulted receivables.

NON-GAAP FINANCIAL MEASURES
Adjusted EBITDA
Adjusted EBITDA is a non-GAAP financial measure that we define as net income (loss) less equity earnings from unconsolidated investment, net income attributable to non-controlling interest and gain on reserve swap; plus total distributions from unconsolidated investment, interest expense, net, debt modification expense, loss on extinguishment of debt, depreciation, depletion and amortization and asset impairments. Adjusted EBITDA should not be considered an alternative to, or more meaningful than, net income or loss, net income or loss attributable to partners, operating income, cash flows from operating activities or any other measure of financial performance presented in accordance with GAAP as measures of operating performance, liquidity or ability to service debt obligations. There are significant limitations to using Adjusted EBITDA as a measure of performance, including the inability to analyze the effect of certain recurring items that materially affect our net income, the lack of comparability of results of operations of different companies and the different methods of calculating Adjusted EBITDA reported by different companies. In addition, Adjusted EBITDA presented below is not calculated or presented on the same basis as Consolidated EBITDA as defined in our partnership agreement or Consolidated EBITDDA as defined in Opco's debt agreements. For a description of Opco's debt agreements, see Note 8. Debt, Net in the Notes to Consolidated Financial Statements included herein as well as in "Item 8. Financial Statements and Supplementary Data—Note 11. Debt, Net" in our Annual Report on Form 10-K for the year ended December 31, 2020. Adjusted EBITDA is a supplemental performance measure used by our management and by external users of our financial statements, such as investors, commercial banks, research analysts and others to assess the financial performance of our assets without regard to financing methods, capital structure or historical cost basis.

Distributable Cash Flow
Distributable cash flow ("DCF") represents net cash provided by (used in) operating activities of continuing operations plus distributions from unconsolidated investment in excess of cumulative earnings, proceeds from asset sales and disposals, including sales of discontinued operations, and return of long-term contract receivables; less maintenance capital expenditures and distributions to non-controlling interest. DCF is not a measure of financial performance under GAAP and should not be considered as an alternative to cash flows from operating, investing or financing activities. DCF may not be calculated the same for us as for other companies. In addition, DCF presented below is not calculated or presented on the same basis as distributable cash flow as defined in our partnership agreement, which is used as a metric to determine whether we are able to increase quarterly distributions to our common unitholders. DCF is a supplemental liquidity measure used by our management and by external users of our financial statements, such as investors, commercial banks, research analysts and others to asses our ability to make cash distributions and repay debt.
Free Cash Flow
Free cash flow ("FCF") represents net cash provided by (used in) operating activities of continuing operations plus distributions from unconsolidated investment in excess of cumulative earnings and return of long-term contract receivables; less maintenance and expansion capital expenditures, cash flow used in acquisition costs classified as investing or financing activities. FCF is calculated before mandatory debt repayments. FCF is not a measure of financial performance under GAAP and should not be considered as an alternative to cash flows from operating, investing or financing activities. FCF may not be calculated the same for us as for other companies. FCF is a supplemental liquidity measure used by our management and by external users of our financial statements, such as investors, commercial banks, research analysts and others to assess our ability to make cash distributions and repay debt.

Executive Overview
We are a diversified natural resource company engaged principally in the business of owning, managing and leasing a diversified portfolio of mineral properties in the United States, including interests in coal and other natural resources and own a non-controlling 49% interest in Ciner Wyoming, a trona ore mining and soda ash production business. Our common units trade on the New York Stock Exchange under the symbol "NRP." Our business is organized into two operating segments:
Coal Royalty and Other—consists primarily of coal royalty properties and coal-related transportation and processing assets. Other assets include industrial mineral royalty properties, aggregates royalty properties, oil and gas royalty properties and timber. Our coal reserves are primarily located in Appalachia, the Illinois Basin and the Northern Powder River Basin in the United States. Our industrial minerals and aggregates properties are located in various states across the United States, our oil and gas royalty assets are primarily located in Louisiana and our timber assets are primarily located in West Virginia.
Soda Ash—consists of our 49% non-controlling equity interest in Ciner Wyoming, a trona ore mining and soda ash production business located in the Green River Basin of Wyoming. Ciner Wyoming mines the trona and processes it into soda ash that is sold both domestically and internationally into the glass and chemicals industries.
Corporate and Financing includes functional corporate departments that do not earn revenues. Costs incurred by these departments include interest and financing, corporate headquarters and overhead, centralized treasury, legal and accounting and other corporate-level activity not specifically allocated to a segment.
Our financial results by segment for the three months ended March 31, 2021 are as follows:

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 of 2020, prices remain below pre-pandemic levels, and the coal and soda ash markets remain challenged. We are unable to predict the ultimate severity or duration of the COVID-19 pandemic or its impact on our or Ciner Wyoming's business. We generated $23.7 million of free cash flow during the quarter ended March 31, 2021, and ended the quarter with $196.8 million of liquidity consisting of $96.8 million of cash and cash equivalents and $100.0 million of borrowing capacity under our Opco Credit Facility. As a result, we believe we have the financial flexibility to navigate the effects of the pandemic on our business. We continue to employ remote work protocols and are conducting business as usual despite the pandemic.

Despite our liquidity level at the end of the quarter, our consolidated leverage ratio has risen since early 2020 and was 4.5x at March 31, 2021. 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 has declared a distribution on our preferred units to be paid one-half in kind through the issuance of additional preferred units (“PIK units”) for the past three quarters. We expect our leverage ratio to continue to rise through the second quarter of 2021 and then begin to decline as we continue to pay down debt. Under the terms of our partnership agreement, to the extent our consolidated leverage ratio remains above 3.75x into 2022 and we therefore remain unable to redeem any outstanding paid-in-kind preferred units, we may be required to temporarily suspend distributions on our common units until the leverage ratio drops below 3.75x and the outstanding paid-in-kind preferred 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, covenants in our debt and partnership agreements, 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
Metallurgical coal markets remain challenged by the uncertainties around the COVID-19 pandemic, however prices have rebounded from the lows seen in the second quarter of 2020 and the outlook continues to strengthen. Domestic and export thermal coal markets continue to stabilize, but still face ongoing negative effects of the COVID-19 pandemic and the long-term challenges of lower utility demand, low natural gas prices, and the secular shift to renewable energy. Our lessees sold 6.6 million tons of coal from our properties in the first three months of 2021 and we derived approximately 50% of our coal royalty revenues and approximately 40% of our coal royalty sales volumes from metallurgical coal during the same period. In addition, we do not have significant sensitivity to thermal coal price movements primarily due to our lease amendments with Foresight Energy which we entered into in 2020.
Soda Ash Business Segment
While Ciner Wyoming's business has yet to recover to pre-COVID levels, overall sales volumes increased and overall production volumes increased over second quarter 2020 lows, though global prices remain depressed. While we believe Ciner Wyoming's facility is competitively positioned as one of the lowest cost producers of soda ash in the world, we expect the market to remain volatile as a result of ongoing uncertainties with the COVID-19 pandemic.
Revenues and other income in the first quarter of 2021 were lower by $4.3 million compared to the prior year quarter primarily as a result of lower sales prices due to demand disruptions caused by the COVID-19 pandemic.
In order to have financial flexibility during the COVID-19 pandemic, Ciner Wyoming suspended its regular quarterly distributions in the third quarter of 2020. Ciner Wyoming will continue 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. Distributions received from Ciner Wyoming were $3.9 million in the first quarter of 2021 as compared to $7.1 million in the first quarter of 2020. Although Ciner Wyoming made a special distribution to its members in the first quarter of 2021, we do not believe Ciner Wyoming will resume regular quarterly distributions until they have greater visibility and confidence in global soda markets.

When considering the significant investment required by Ciner Wyoming’s previously announced expansion project and the infrastructure improvements designed to increase overall efficiency, combined with the COVID-19 pandemic’s negative impact on Ciner Wyoming’s financial results, Ciner Wyoming has reprioritized the timing of the significant capital expenditure items in order to increase financial and liquidity flexibility until it has more clarity and visibility into the ongoing impact of the COVID-19 pandemic on its business.

Coal Royalty Revenues
Total coal royalty revenues decreased $3.7 million during the three months ended March 31, 2021 as compared to the prior year quarter primarily as a result of certain revenues previously classified as coal royalty revenues that are now classified as production lease minimum revenues or minimum lease straight-line revenues due to contract modifications with Foresight as mentioned above. Excluding the impacts of these reclassifications, coal royalty revenues increased $1.2 million period over period. The discussion by region is as follows:
Appalachia: Coal royalty revenues decreased $3.5 million primarily due to a 18% decrease in sales volumes primarily driven by the termination of certain coal leases in 2020 as a result of weakened coal markets compounded by the COVID-19 pandemic.
Illinois Basin: Coal royalty revenues increased $3.3 million primarily due to a 426% increase in sales volumes, partially offset by a 53% decrease in sales prices as compared to the prior year quarter.
Northern Powder River Basin: Sales volumes increased 101% and coal royalty revenues increased $1.4 million primarily due to our lessee mining on our property in accordance with its mine plan in 2021, partially offset by a 18% decrease in sales prices as compared to the prior year quarter.
Other Revenues
Other revenues increased $5.2 million primarily due to a $2.6 million increase in production lease minimum revenues and a $2.3 million increase in minimum lease straight-line revenues, both primarily a result of the contract modifications with Foresight as discussed above.
Soda Ash

Revenues and other income related to our Soda Ash segment decreased $4.3 million compared to the prior year quarter primarily as a result of lower sales prices due to demand disruptions caused by the COVID-19 pandemic

Operating Expenses

Total operating expenses$18,797 $11,127 $7,670 69 %

Total operating expenses increased $7.7 million primarily due to a $4.0 million increase in asset impairments as a result of lease termination, and a $3.1 million increase in depreciation, depletion and amortization expense as a result of increased production at certain Illinois Basin coal properties. The remaining $0.6 million increase was due to a $1.3 million increase in certain costs primarily driven by increased bad debt expense, partially offset by a $0.7 million reduction in controllable costs as a result of our cost saving initiatives.

DCF and FCF decreased $6.6 million and $6.7 million, respectively, primarily due to the following:
Coal Royalty and Other Segment
DCF and FCF decreased $4.3 million primarily as a result of lease amendment fee payments received in the first quarter of 2020.
Soda Ash Segment
DCF and FCF decreased $3.2 million as a result of lower cash distributions received from Ciner Wyoming in the first three months of 2021 as compared to the prior year period.
Liquidity and Capital Resources
Current Liquidity
As of March 31, 2021, we had total liquidity of $196.8 million, consisting of $96.8 million of cash and cash equivalents and $100.0 million of borrowing capacity under our Opco Credit Facility. We have significant debt service obligations, including approximately $23 million of principal repayments on Opco’s senior notes throughout the remainder of 2021. We believe our liquidity position provides us with the flexibility to continue paying down debt and manage our business through the current market environment.
Cash Flows
Cash flows provided by operating activities decreased $8.7 million, from $31.9 million in the three months ended March 31, 2020 to $23.2 million in the three months ended March 31, 2021 primarily related to lower operating cash flow as a result of lease amendment fee payments received in the first quarter of 2020 in addition to lower cash distributions received from Ciner Wyoming in the first three months of 2021 as compared to the prior year quarter.
Cash flows used in financing activities decreased $3.0 million, from $29.8 million in the three months ended March 31, 2020 to $26.8 million in the three months ended March 31, 2021 primarily due to lower preferred unit cash distributions in the first quarter of 2021 as a result of paying half of the distribution in kind through the issuance of additional preferred units.
