NACCO INDUSTRIES, INC. AND SUBSIDIARIES

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

JUNE 30, 2020

(In thousands, except as noted and per share amounts)

NOTE 1—Nature of Operations and Basis of Presentation

The accompanying Unaudited Condensed Consolidated Financial Statements include the accounts of NACCO Industries, Inc.^® (“NACCO”) and its wholly owned subsidiaries (collectively, “NACCO Industries, Inc. and Subsidiaries” or the “Company”). Intercompany accounts and transactions are eliminated in consolidation. NACCO is the public holding company for The North American Coal Corporation^® ("NACoal"). The Company has three operating segments: Coal Mining, North American Mining (“NAMining”) and Minerals Management. The Company also has unallocated items not directly attributable to a reportable segment. See Note 9 to the Unaudited Condensed Consolidated Financial Statements for further discussion of segment reporting.

The Company’s operating segments are further described below:

Coal Mining Segment

During the six months ended June 30, 2020, the operating coal mines are: Bisti Fuels LLC (“Bisti”), Caddo Creek Resources Company, LLC (“Caddo Creek”), Camino Real Fuels, LLC (“Camino Real”), The Coteau Properties Company (“Coteau”), Coyote Creek Mining Company, LLC (“Coyote Creek”), Demery Resources Company, LLC (“Demery”), The Falkirk Mining Company (“Falkirk”), Mississippi Lignite Mining Company (“MLMC”) and The Sabine Mining Company (“Sabine”).

The contract mining agreement between Camino Real and its customer, Dos Republicas Coal Partnership (“DRCP”), terminated effective July 1, 2020 as a result of the unexpected termination by Comisión Federal de Electricidad (“CFE”) of its coal supply contract with an affiliate of DRCP. The termination of the contract between CFE and DRCP eliminated DRCP’s need for coal from Camino Real's Eagle Pass Mine, and will result in mine closure.

Camino Real issued a Notice of Payment Default on June 17, 2020. During the third quarter of 2020, the Company received certain inventory as well as a securitized note in settlement of the outstanding receivable balance as of June 30, 2020 and additional costs incurred through the July 9, 2020 mine closure date. Mine reclamation is the responsibility of DRCP. Camino Real has no legal obligation to perform mine reclamation but is in negotiations with DRCP to potentially perform mine reclamation activities under a new contractual arrangement. Closure of the mine does not materially impact NACCO’s outlook for 2020. The contract mining agreement between Camino Real and DRCP was previously expected to terminate in 2021.

As of June 30, 2020, all of the Liberty Fuels Company, LLC mine areas have been reclaimed and final mine reclamation activities, primarily monitoring, will continue until final bond release.

At all operating coal mines other than MLMC, the Company is paid a management fee per ton of coal or heating unit (MMBtu) delivered. Each contract specifies the indices and mechanics by which fees change over time, generally in line with broad measures of U.S. inflation. The customers are responsible for funding all mine operating costs, including final mine reclamation, and directly or indirectly providing all of the capital required to build and operate the mine. This contract structure eliminates exposure to spot coal market price fluctuations while providing steady income and cash flow with minimal capital investment. Other than at Coyote Creek, debt financing provided by or supported by the customers is without recourse to NACCO and NACoal. See Note 7 for further discussion of Coyote Creek's guarantees.

All operating coal mines other than MLMC meet the definition of a variable interest entity (“VIE”). In each case, NACCO is not the primary beneficiary of the VIE as it does not exercise financial control; therefore, NACCO does not consolidate the results of these operations within its financial statements. Instead, these contracts are accounted for as equity method investments. The income before income taxes associated with these VIE's is reported as Earnings of unconsolidated operations on the Consolidated Statements of Operations and the Company’s investment is reported on the line Investments in unconsolidated subsidiaries in the Consolidated Balance Sheets. The mines that meet the definition of a VIE are referred to collectively as the “Unconsolidated Subsidiaries.” For tax purposes, the Unconsolidated Subsidiaries are included within the NACCO consolidated U.S. tax return; therefore, the income tax expense line on the Consolidated Statements of Operations includes income taxes related to these entities. All of the Unconsolidated Subsidiaries are accounted for under the equity method. See Note 7 for further discussion.

Camino Real previously met the definition of a variable interest entity of which the Company was not the primary beneficiary and therefore NACCO did not consolidate Camino Real’s results of operations within its financial statements.

7

The Notice of Payment Default and subsequent termination of the contract mining agreement resulted in a reconsideration event, which required reassessment of the Company’s VIE conclusion. As a result of this reconsideration, Camino Real is no longer a VIE and its financial position is consolidated within NACCO’s financial statements as of June 30, 2020. The consolidation of Camino Real did not materially change the Company’s balance sheet. The results of operations for the six months ended June 30, 2020 are reported under the equity method with income before income taxes reported as Earnings of unconsolidated operations on the Consolidated Statements of Operations.  

The MLMC contract is the only operating coal contract in which the Company is responsible for all operating costs, capital requirements and final mine reclamation; therefore, MLMC is consolidated within NACCO’s financial statements. MLMC sells coal to its customer at a contractually agreed-upon price which adjusts monthly, primarily based on changes in the level of established indices which reflect general U.S. inflation rates.

Centennial Natural Resources (“Centennial”), located in Alabama, ceased coal production at the end of 2015. Since 2015, the Company has sold or transferred certain Centennial equipment and mineral reserves. The Company continues to evaluate strategies for the remaining mineral reserves and a dragline, which have no remaining book value. Cash expenditures related to mine reclamation at Centennial will continue until mine reclamation is complete, or ownership of, or responsibility for, the remaining mines is transferred. Centennial is a consolidated entity within the Coal Mining segment as the Company is responsible for carrying costs and final mine reclamation.

NAMining Segment

The NAMining segment provides value-added contract mining and other services for producers of aggregates, lithium and other minerals. The segment is a primary platform for the Company’s growth and diversification outside of the coal industry. NAMining provides contract mining services for independently owned mines and quarries, creating value for its customers by performing the mining aspects of its customers’ operations. This allows customers to focus on their areas of expertise: materials handling and processing, product sales and distribution. NAMining operates primarily at limestone quarries in Florida, but is focused on expanding outside of Florida and into mining materials other than limestone. During 2019, the Company entered into a mining agreement to serve as exclusive contract miner for the Thacker Pass lithium project in northern Nevada. NAMining utilizes both fixed price and cost plus management fee contract structures. Certain of the entities within NAMining segment are VIEs and are accounted for under the equity method as Unconsolidated Subsidiaries. See Note 7 for further discussion.

Minerals Management Segment

The Minerals Management segment promotes the development of the Company’s gas, oil and coal reserves, generating income primarily from royalty-based lease payments from third parties. The Company’s gas, oil and undeveloped coal reserves are located in Ohio (Utica and Marcellus shale natural gas), Louisiana (Haynesville shale and Cotton Valley formation natural gas), Mississippi (coal), Pennsylvania (coal, coalbed methane and Marcellus shale natural gas), Alabama (coal and coalbed methane and natural gas) and North Dakota (coal).

The majority of the Company’s existing reserves were acquired as part of its historical coal mining operations. The Minerals Management segment derives income primarily by entering into contracts with third-party operators, granting them the rights to explore, produce and sell natural resources in exchange for royalty payments based on the lessees' sales of natural gas and, to a lesser extent, oil and coal. Specialized employees in the Minerals Management segment also provide surface and mineral acquisition and lease maintenance services related to Company operations.

Basis of Presentation: These financial statements have been prepared in accordance with U.S. generally accepted accounting principles ("U.S. GAAP") for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation of the financial position of the Company at June 30, 2020, the results of its operations, comprehensive income, cash flows and changes in equity for the six months ended June 30, 2020 and 2019 have been included. These Unaudited Condensed Consolidated Financial Statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2019.

The balance sheet at December 31, 2019 has been derived from the audited financial statements at that date but does not include all of the information or notes required by U.S. GAAP for complete financial statements.

Certain amounts in prior period Unaudited Condensed Consolidated Financial Statements have been reclassified to conform to the current period's presentation.

NOTE 2—Revenue Recognition

Nature of Performance Obligations

At contract inception, the Company assesses the goods and services promised in its contracts with customers and identifies a performance obligation for each promised good or service that is distinct. To identify the performance obligations, the Company considers all of the goods or services promised in the contract regardless of whether they are explicitly stated or are implied by customary business practices.

Each mine or mine area has a contract with its respective customer that represents a contract under ASC 606. For its consolidated entities, the Company’s performance obligations vary by contract and consist of the following:

At MLMC, each MMBtu delivered during the production period is considered a separate performance obligation. Revenue is recognized at the point in time that control of each MMBtu of lignite transfers to the customer. Fluctuations in revenue from period to period generally result from changes in customer demand.

At NAMining entities, the management service to oversee the operation of the equipment and delivery of limestone is the performance obligation accounted for as a series. Performance momentarily creates an asset that the customer simultaneously receives and consumes; therefore, control is transferred to the customer over time. Consistent with the conclusion that the customer simultaneously receives and consumes the benefits provided, an input-based measure of progress is appropriate. As each month of service is completed, revenue is recognized for the amount of actual costs incurred, plus the management fee and the general and administrative fee (as applicable). Fluctuations in revenue from period to period result from changes in customer demand and variances in reimbursable costs primarily due to increases and decreases in activity levels on individual contracts.

The Company enters into royalty contracts which grant the right to explore, develop, produce and sell minerals controlled by the Company. These arrangements result in the transfer of mineral rights for a period of time; however, no rights to the actual land are granted other than access for purposes of exploration, development, production and sales. The mineral rights revert back to the Company at the expiration of the contract.

Under these royalty contracts, granting exclusive right, title, and interest in and to minerals, if any, is the performance obligation. The performance obligation under these contracts represents a series of distinct goods or services whereby each day of access that is provided is distinct. The transaction price consists of a variable sales-based royalty and, in certain arrangements, a fixed component in the form of an up-front lease bonus payment. As the amount of consideration the Company will ultimately be entitled to is entirely susceptible to factors outside its control, the entire amount of variable consideration is constrained at contract inception. The fixed portion of the transaction price will be recognized over the primary term of the contract, which is generally five years.

Significant Judgments

The Company’s contracts with its customers contain different types of variable consideration including, but not limited to, management fees that adjust based on coal volumes or MMBtu delivered or limestone yards, however, the terms of these variable payments relate specifically to the Company's efforts to satisfy one or more, but not all of, the performance obligations (or to a specific outcome from satisfying the performance obligations), in the contract. Therefore, the Company allocates each variable payment (and subsequent changes to that payment) entirely to the specific performance obligation to which it relates. Management fees, as well as general and administrative fees, are also adjusted based on changes in specified indices (e.g., CPI) to compensate for general inflation changes. Index adjustments, if applicable, are effective prospectively. Certain contracts include reimbursement of actual costs incurred.

Disaggregation of Revenue

In accordance with ASC 606-10-50, the Company disaggregates revenue from contracts with customers into major goods and service lines and timing of transfer of goods and services. The Company determined that disaggregating revenue into these categories achieves the disclosure objective of depicting how the nature, amount, timing, and uncertainty of revenue and cash flows are affected by economic factors. The Company’s business consists of the Coal Mining, NAMining and Minerals Management segments as well as Unallocated Items. See Note 9 to the Unaudited Condensed Consolidated Financial Statements for further discussion of segment reporting.

Contract Balances

The opening and closing balances of the Company’s current and long-term contract liabilities and receivables are as follows:

	Contract balances
	Trade accounts receivable, net		Contract liability (current)			Contract liability (long-term)
Balance, January 1, 2020	$	15,444	$	944		$	2,153
Balance, June 30, 2020	20,335		941			1,683
Increase (decrease)	$	4,891	$	(3	)	$	(470	)

As described above, the Company enters into royalty contracts that grant exclusive right, title, and interest in and to minerals. The transaction price consists of a variable sales-based royalty and, in certain arrangements, a fixed component in the form of an up-front lease bonus payment. The timing of the payment of the fixed portion of the transaction price is upfront, however, the performance obligation is satisfied over the primary term of the contract, which is generally five years. Therefore, at the time any such up-front payment is received, a contract liability is recorded which represents deferred revenue. The difference between the opening and closing balance of this contract liability, which is shown above, primarily results from the difference between new lease bonus payments received and amortization of up-front lease bonus payments received in previous periods.

The amount of revenue recognized in the three months ended June 30, 2020 and June 30, 2019 that was included in the opening contract liability was $0.3 million and $0.2 million, respectively. The amount of revenue recognized in the six months ended June 30, 2020 and June 30, 2019 that was included in the opening contract liability was $0.5 million and $0.4 million, respectively. This revenue consists of up-front lease bonus payments received under royalty contracts that are recognized over the primary term of the royalty contracts, which are generally five years. The Company expects to recognize an additional $0.5 million in the remainder of 2020, $0.9 million in 2021, $0.7 million in 2022, $0.3 million in 2023, and $0.1 million in 2024 related to the contract liability remaining at June 30, 2020. The difference between the opening and closing balances of the Company’s accounts receivable and contract liabilities results from the timing difference between the Company’s performance and the customer’s payment. Contracts with payments in arrears are recognized as receivables.

The Company has no contract assets recognized from the costs to obtain or fulfill a contract with a customer.

NOTE 3—Inventories

Inventories are summarized as follows:

	JUNE 30 2020		DECEMBER 31 2019
Coal	$	8,929	$	15,700
Mining supplies	26,803		24,765
Total inventories	$	35,732	$	40,465

NOTE 4—Leases

NACCO adopted ASU 2016-02, Leases (Topic 842), on January 1, 2019. The most significant effect to the Unaudited Condensed Consolidated Balance Sheets relates to the recognition of new right-of-use assets and lease liabilities for operating leases of real estate, mining and other equipment that expire at various dates through 2031. The majority of the Company's leases are operating leases. See the table below for further information on the balances included in the Unaudited Condensed Consolidated Balance Sheets. Several leases include renewal or fair value purchase options, which are not recognized on the Unaudited Condensed Consolidated Balance Sheets. The Company's lease agreements do not contain lease payments that depend on an index or a rate, as such, minimum lease payments do not include variable lease payments.

Leased assets and liabilities include the following:

Description	Location	JUNE 30 2020		DECEMBER 31 2019
Assets
Operating	Operating lease right-of-use assets	$	10,748	$	11,398
Finance	Property, plant and equipment, net (a)	$	98	$	544
Liabilities
Current
Operating	Other current liabilities	$	1,308	$	1,318
Finance	Current maturities of long-term debt	$	33	$	558
Noncurrent
Operating	Operating lease liabilities	$	11,782	$	12,448
Finance	Long-term debt	$	68	$	85

^(a) Finance leased assets are recorded net of accumulated amortization of less than $0.1 million and $1.9 million as of June 30, 2020 and December 31, 2019, respectively.

The components of lease expense were as follows:

		THREE MONTHS ENDED				SIX MONTHS ENDED
		JUNE 30				JUNE 30
Description	Location	2020		2019		2020		2019
Lease expense
Operating lease cost	Selling, general and administrative expenses	$	504	$	589	$	1,014	$	1,214
Finance lease cost:
Amortization of leased assets	Cost of sales	9		100		103		196
Interest on lease liabilities	Interest expense	1		3		6		6
Variable lease expense	Selling, general and administrative expenses	137		175		287		276
Short-term lease expense	Selling, general and administrative expenses	45		89		159		163
Total lease expense		$	696	$	956	$	1,569	$	1,855

11

Future minimum finance and operating lease payments were as follows at June 30, 2020:

	Finance Leases		Operating Leases		Total
Remainder of 2020	$	19	$	1,077	$	1,096
2021	37		2,135		2,172
2022	37		2,174		2,211
2023	16		1,693		1,709
2024	—		1,663		1,663
Subsequent to 2024	—		9,330		9,330
Total minimum lease payments	$	109	$	18,072	$	18,181
Amounts representing interest	8		4,982
Present value of net minimum lease payments	$	101	$	13,090

As most of the Company's leases do not provide an implicit rate, the Company determines the incremental borrowing rate based on the information available at the lease commencement date in determining the present value of lease payments. The Company considers its credit rating and the current economic environment in determining this collateralized rate.

The assumptions used in accounting for ASC 842 were as follows:

	THREE MONTHS ENDED				SIX MONTHS ENDED
	JUNE 30				JUNE 30
Lease term and discount rate	2020		2019		2020		2019
Weighted average remaining lease term (years)

NOTE 5—Stockholders' Equity

Stock Repurchase Program: On November 6, 2019, the Company's Board of Directors approved a stock purchase program ("2019 Stock Repurchase Program") providing for the purchase of up to $25 million of the Company's outstanding Class A Common Stock through December 31, 2021. NACCO's previous repurchase program ("2018 Stock Repurchase Program") would have expired on December 31, 2019 but was terminated and replaced by the 2019 Stock Repurchase Program. As a result of the uncertainty surrounding the COVID-19 pandemic, the Company suspended repurchasing shares under the 2019 Stock Repurchase Program in March 2020. Prior to the decision to cease share repurchases, the Company repurchased 32,286 shares of Class A Common Stock under the 2019 Stock Repurchase Program for an aggregate purchase price of $1.0 million during the six months ended June 30, 2020. During the three and six months ended June 30, 2019, the Company repurchased 2,230 and 38,524 shares, respectively, of Class A Common Stock under the 2018 Stock Repurchase Program for an aggregate purchase price of $0.1 million and $1.4 million, respectively.

The timing and amount of any repurchases under the 2019 Stock Repurchase Program are determined at the discretion of the Company's management based on a number of factors, including the availability of capital, other capital allocation alternatives, market conditions for the Company's Class A Common Stock and other legal and contractual restrictions. The 2019 Stock

12

Repurchase Program does not require the Company to acquire any specific number of shares and may be modified, suspended, extended or terminated by the Company without prior notice and may be executed through open market purchases, privately negotiated transactions or otherwise. All or part of the repurchases under the 2019 Stock Repurchase Program may be implemented under a Rule 10b5-1 trading plan, which would allow repurchases under pre-set terms at times when the Company might otherwise be restricted from doing so under applicable securities laws.

Bellaire Corporation (“Bellaire”) is a non-operating subsidiary of the Company with legacy liabilities relating to closed mining operations, primarily former Eastern U.S. underground coal mining operations. Prior to 2019, Bellaire established a $5.0 million mine water treatment trust (the "Mine Water Treatment Trust") to provide a financial assurance mechanism to assure the long-term treatment of post-mining discharge. Bellaire's Mine Water Treatment Trust invests in equity securities that are reported at fair value based upon quoted market prices in active markets for identical assets; therefore, they are classified as Level 1 within the fair value hierarchy. The Company recognized a gain of $1.1 million and a loss of $0.1 million in the three and six months ended June 30, 2020, respectively, and a gain of $0.3 million and $1.0 million in the three and six months ended June 30, 2019, respectively, related to the Mine Water Treatment Trust.

During the second quarter of 2020, the Company invested $2.0 million in equity securities of a public company with a diversified portfolio of royalty producing mineral interests. The investment is reported at fair value based upon quoted market prices in active markets for identical assets; therefore, it is classified as Level 1 within the fair value hierarchy. The Company recognized a gain of $0.4 million in both the three and six months ended June 30, 2020 related to the investment in these equity securities.

The gains and losses related to equity securities are reported on the line Gain on equity securities in the Other (income) expense section of the Unaudited Condensed Consolidated Statements of Operations.

There were no transfers into or out of Levels 1, 2 or 3 during the three and six months ended June 30, 2020 and 2019.

NOTE 7—Unconsolidated Subsidiaries

Each of NACoal's wholly owned Unconsolidated Subsidiaries, within the Coal Mining and NAMining segments, meet the definition of a VIE. The Unconsolidated Subsidiaries are capitalized primarily with debt financing provided by or supported by their respective customers, and other than at Coyote Creek, without recourse to NACCO and NACoal. Although NACoal owns 100% of the equity and manages the daily operations of the Unconsolidated Subsidiaries, the Company has determined that the equity capital provided by NACoal is not sufficient to adequately finance the ongoing activities or absorb any expected losses without additional support from the customers. The customers have a controlling financial interest and have the power to direct the activities that most significantly affect the economic performance of the entities. As a result, the Company is not the primary beneficiary and therefore does not consolidate these entities' financial positions or results of operations. See Note 1 for a discussion of these entities.

13

The Investment in the unconsolidated subsidiaries and related tax positions totaled $25.3 million and $24.6 million at June 30, 2020 and December 31, 2019, respectively. The Company's maximum risk of loss relating to these entities is limited to its invested capital, which was $5.3 million and $5.0 million at June 30, 2020 and December 31, 2019, respectively.

NACoal is a party to certain guarantees related to Coyote Creek. Under certain circumstances of default or termination of Coyote Creek’s Lignite Sales Agreement (“LSA”), NACoal would be obligated for payment of a "make-whole" amount to Coyote Creek’s third-party lenders. The “make-whole” amount is based on the excess, if any, of the discounted value of the remaining scheduled debt payments over the principal amount. In addition, in the event Coyote Creek’s LSA is terminated on or after January 1, 2024 by Coyote Creek’s customers, NACoal is obligated to purchase Coyote Creek’s dragline and rolling stock for the then net book value of those assets. To date, no payments have been required from NACoal since the inception of these guarantees. The Company believes that the likelihood NACoal would be required to perform under the guarantees is remote, and no amounts related to these guarantees have been recorded.

Summarized financial information for the Unconsolidated Subsidiaries is as follows:

	THREE MONTHS ENDED				SIX MONTHS ENDED
	JUNE 30				JUNE 30
	2020		2019		2020		2019
Gross profit	$	15,176	$	14,631	$	31,746	$	33,767
Income before income taxes	$	13,803	$	14,516	$	30,044	$	31,253

NOTE 8—Contingencies

Various legal and regulatory proceedings and claims have been or may be asserted against NACCO and certain subsidiaries relating to the conduct of their businesses. These proceedings and claims are incidental to the ordinary course of business of the Company. Management believes that it has meritorious defenses and will vigorously defend the Company in these actions. Any costs that management estimates will be paid as a result of these claims are accrued when the liability is considered probable and the amount can be reasonably estimated.  If a range of amounts can be reasonably estimated and no amount within the range is a better estimate than any other amount, then the minimum of the range is accrued. The Company does not accrue liabilities when the likelihood that the liability has been incurred is probable but the amount cannot be reasonably estimated or when the liability is believed to be only reasonably possible or remote. For contingencies where an unfavorable outcome is probable or reasonably possible and which are material, the Company discloses the nature of the contingency and, in some circumstances, an estimate of the possible loss. 

These matters are subject to inherent uncertainties, and unfavorable rulings could occur. If an unfavorable ruling were to occur, there exists the possibility of an adverse impact on the Company’s financial position, results of operations and cash flows of the period in which the ruling occurs, or in future periods.

NOTE 9—Business Segments

The Company's operating segments are: (i) Coal Mining, (ii) NAMining and (iii) Minerals Management. While the Company continues to pursue opportunities to add new coal mining operations to the Coal Mining segment, the NAMining segment serves as the platform for pursuing non-coal mining projects and the Minerals Management segment promotes the development of the Company's gas, oil and coal reserves.

The Company determines its reportable segments by first identifying its operating segments, and then by assessing whether any components of these segments constitute a business for which discrete financial information is available and where segment management regularly reviews the operating results of that component. The Company’s Chief Operating Decision Maker utilizes operating profit to evaluate segment performance and allocate resources.

The Company also has unallocated items not directly attributable to a reportable segment which are not included as part of the measurement of segment operating profit, primarily administrative costs related to public company reporting requirements, the financial results of the Company’s mitigation banking business, Mitigation Resources of North America^® (“MRNA”), and Bellaire. MRNA generates and sells stream and wetland mitigation credits (known as mitigation banking) and provides services to those engaged in permittee-responsible stream and wetland mitigation. Bellaire manages the Company’s long-term liabilities related to former Eastern U.S. underground mining activities. Transactions between segments are accounted for as third-party arrangements for purposes of presenting segment results of operations and are eliminated in consolidation.

14

As of January 1, 2020, the Company retrospectively changed its computation of segment operating profit to reclassify certain expenses, primarily related to executive and board compensation. These expenses are now included in unallocated items. The change in segment reporting reflected a decision to evaluate the financial performance of the Company’s segments excluding executive and board compensation. All prior period segment information has been reclassified to conform to the new presentation. This segment reporting change has no impact on consolidated operating results.

All financial statement line items below operating profit (other income including interest expense and interest income, the provision for income taxes and net income) are presented and discussed within this Form 10-Q on a consolidated basis. Included within other income on the line Income from other unconsolidated affiliates within the Unaudited Condensed Consolidated Statements of Operations is the financial results of NoDak Energy Services, LLC ("NoDak"). NoDak operated and maintained a coal drying system at a customer’s power plant. The NoDak contract expired in the first quarter of 2020.

See Note 1 for additional discussion of the Company's reportable segments. The following tables present revenue, operating profit, depreciation expense and capital expenditures:

NOTE 10—Income Taxes

The Company evaluates and updates its estimated annual effective income tax rate on a quarterly basis based on current and forecasted operating results and tax laws. Consequently, based upon the mix and timing of actual earnings compared to projections of earnings between entities that benefit from percentage depletion and those that do not, the effective tax rate may

15

vary quarterly. The quarterly income tax provision is generally comprised of tax expense on income or a benefit on a loss at the most recent estimated annual effective income tax rate, adjusted for the effect of discrete items.

On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act ("CARES Act") was enacted in response to the COVID-19 pandemic. The CARES Act contains numerous income tax provisions, including among other items, temporary changes regarding the prior and future utilization of net operating losses. The CARES Act allows net operating losses incurred in 2018, 2019, and 2020 to be carried back to each of the five preceding taxable years to generate a refund of previously paid income taxes. The 2020 estimated annual effective tax rate includes the benefit of utilizing the current year forecasted tax basis net operating loss that would otherwise be deductible at the current 21% statutory rate to offset taxable income in years that were taxed at a 35% rate. The Company expects to generate a net operating loss in 2020 primarily due to the realization of certain deferred tax assets. The Company is currently assessing aspects of the CARES Act, including the Company’s ability to utilize the extended carryback provisions.

Item 2. - Management's Discussion and Analysis of Financial Condition and Results of Operations

(Dollars in thousands, except as noted and per share data)

Management's Discussion and Analysis of Financial Condition and Results of Operations contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. These statements are based upon management's current expectations and are subject to various uncertainties and changes in circumstances. Important factors that could cause actual results to differ materially from those described in these forward-looking statements are set forth below under the heading “Forward-Looking Statements."

Management's Discussion and Analysis of Financial Condition and Results of Operations include NACCO Industries, Inc.^® (“NACCO”) and its wholly owned subsidiaries (collectively, the “Company”). NACCO is the public holding company for The North American Coal Corporation^®. The North American Coal Corporation and its affiliated companies (collectively, “NACoal”) operate in the mining and natural resources industries through three operating segments: Coal Mining, North American Mining ("NAMining") and Minerals Management. The Coal Mining segment operates surface coal mines under long-term contracts with power generation companies and activated carbon producers pursuant to a service-based business model. The NAMining segment provides value-added contract mining and other services for producers of aggregates, lithium and other minerals. The Minerals Management segment promotes the development of the Company’s gas, oil and coal reserves, generating income primarily from royalty-based lease payments from third parties.

The Company also has unallocated items not directly attributable to a reportable segment which are not included as part of the measurement of segment operating profit, primarily administrative costs related to public company reporting requirements, the financial results of the Company’s mitigation banking business, Mitigation Resources of North America^® (“MRNA”), and Bellaire Corporation (“Bellaire”). MRNA generates and sells stream and wetland mitigation credits (known as mitigation banking) and provides services to those engaged in permittee-responsible stream and wetland mitigation. Bellaire manages the Company’s long-term liabilities related to former Eastern U.S. underground mining activities.

As of January 1, 2020, the Company retrospectively changed its computation of segment operating profit to reclassify certain expenses, primarily related to executive and board compensation. These expenses are now included in unallocated items. The change in segment reporting reflected a decision to evaluate the financial performance of the Company’s segments excluding executive and board compensation. All prior period segment information has been reclassified to conform to the new presentation. This segment reporting change has no impact on consolidated operating results.

All financial statement line items below operating profit (other income, including interest expense and interest income, the provision for income taxes and net income) are presented and discussed within this Form 10-Q on a consolidated basis.

The Company has continued to operate as an essential business during the COVID-19 pandemic because it supports critical infrastructure industries. The Company has procedures to limit the exposure of employees to the spread of COVID-19. The extent to which COVID-19 impacts the Company going forward will depend on numerous factors and future developments that remain uncertain.

The Company’s operating segments are further described below:

Coal Mining Segment

The Coal Mining segment operates surface coal mines under long-term contracts with power generation companies and activated carbon producers pursuant to a service-based business model. Coal is surface-mined in North Dakota, Texas, Mississippi, Louisiana and on the Navajo Nation in New Mexico. Each mine is fully integrated with its customer operations.

During the six months ended June 30, 2020, the operating coal mines were: Bisti Fuels LLC ("Bisti"), Caddo Creek Resources Company, LLC (“Caddo Creek”), Camino Real Fuels, LLC (“Camino Real”), The Coteau Properties Company (“Coteau”), Coyote Creek Mining Company, LLC (“Coyote Creek”), Demery Resources Company, LLC (“Demery”), The Falkirk Mining Company (“Falkirk”), Mississippi Lignite Mining Company (“MLMC”) and The Sabine Mining Company (“Sabine”).

The contract mining agreement between Camino Real and its customer, Dos Republicas Coal Partnership (“DRCP”), terminated effective July 1, 2020 as a result of the unexpected termination by Comisión Federal de Electricidad (“CFE”) of its coal supply contract with an affiliate of DRCP. The termination of the contract between CFE and DRCP eliminated DRCP’s need for coal from Camino Real's Eagle Pass Mine, and will result in mine closure.

Camino Real issued a Notice of Payment Default on June 17, 2020. During the third quarter of 2020, the Company received certain inventory as well as a securitized note in settlement of the outstanding receivable balance as of June 30, 2020 and

17

additional costs incurred through the July 9, 2020 mine closure date. Mine reclamation is the responsibility of DRCP. Camino Real has no legal obligation to perform mine reclamation but is in negotiations with DRCP to potentially perform mine reclamation activities under a new contractual arrangement. Closure of the mine does not materially impact NACCO’s outlook for 2020. The contract mining agreement between Camino Real and DRCP was previously expected to terminate in 2021.

As of June 30, 2020, all of the Liberty Fuels Company, LLC mine areas have been reclaimed and final mine reclamation activities, primarily monitoring, will continue until final bond release.

Coteau, Coyote, Falkirk, MLMC and Sabine supply lignite coal for power generation. Bisti supplies sub-bituminous coal for power generation. Caddo Creek and Demery supply lignite coal for the production of activated carbon. Each of these mines deliver their coal production to adjacent or nearby power plants, synfuels plants or activated carbon processing facilities under long-term supply contracts. Each operating mine is the exclusive supplier of coal to its customers' facilities.

This segment has a strong history of customer retention due to the long-term nature of its contracts and the proximity of the Company’s mines to its customers’ facilities. The operating mines' contract expiration dates range from 2022 through 2045. The contract that expires in 2022 may be extended for three additional periods of five years each, or until 2037, at the Company’s option.

On May 7, 2020, Great River Energy ("GRE"), Falkirk Mine's customer, and the Company's second largest customer, announced its intent to retire the Coal Creek Station power plant in the second half of 2022 and modify the Spiritwood Station power plant to be fueled by natural gas.

As noted in the announcement, GRE is willing to consider opportunities to sell Coal Creek Station. NACCO is actively engaged in the exploration of options that could, if successful, allow for transfer of ownership of the power plant to one or more third parties, which would preserve jobs at both Coal Creek Station and the Falkirk Mine. The Company believes Coal Creek Station is an efficient, economic and attractive generation and capacity asset, and its continued long-term operation is in the best interests of the employees and the local community.

Falkirk Mine is the sole supplier of lignite coal to Coal Creek Station pursuant to a long-term contract under which Falkirk also supplies approximately 0.3 million tons of lignite coal per year to Spiritwood Station. Falkirk has approximately 480 employees, and, in 2019, delivered a total of 7.4 million tons of lignite coal and contributed approximately $16 million to NACCO’s Earnings from Unconsolidated Operations. The closure of Coal Creek Station would have a material adverse effect on the long-term earnings of NACCO. The terms of the contract between the Company and GRE specify that GRE is responsible for all costs related to mine closure, including but not limited to, final mine reclamation costs, post-retirement medical benefits and pension costs with respect to Falkirk employees.

At all operating coal mines other than MLMC, the Company is paid a management fee per ton of coal or heating unit (MMBtu) delivered. Each contract specifies the indices and mechanics by which fees change over time, generally in line with broad measures of U.S. inflation. The customers are responsible for funding all mine operating costs, including final mine reclamation, and directly or indirectly providing all of the capital required to build and operate the mine. This contract structure eliminates exposure to spot coal market price fluctuations while providing steady income and cash flow with minimal capital investment. Other than at Coyote Creek, debt financing provided by or supported by the customers is without recourse to NACCO and NACoal. See Note 7 of the accompanying Unaudited Condensed Consolidated Financial Statements for further discussion of Coyote Creek's guarantees.

All operating coal mines other than MLMC meet the definition of a variable interest entity (“VIE”). In each case, NACCO is not the primary beneficiary of the VIE as it does not exercise financial control; therefore, NACCO does not consolidate the results of these operations within its financial statements. Instead, these contracts are accounted for as equity method investments. The income before income taxes associated with these VIE's is reported as Earnings of unconsolidated operations on the Consolidated Statements of Operations and the Company’s investment is reported on the line Investments in Unconsolidated Subsidiaries in the Consolidated Balance Sheets. The mines that meet the definition of a VIE are referred to collectively as the “Unconsolidated Subsidiaries.” For tax purposes, the Unconsolidated Subsidiaries are included within the NACCO consolidated U.S. tax return; therefore, the income tax expense line on the Consolidated Statements of Operations includes income taxes related to these entities. The contracts for certain of the Company's Unconsolidated Subsidiaries permit or obligate the customer under some conditions to acquire the assets or stock of the subsidiary for an amount roughly equal to book value.

Camino Real previously met the definition of a variable interest entity of which the Company was not the primary beneficiary and therefore NACCO did not consolidate Camino Real’s results of operations within its financial statements.

18

The Notice of Payment Default and subsequent termination of the contract mining agreement resulted in a reconsideration event, which required reassessment of the Company’s VIE conclusion. As a result of this reconsideration, Camino Real is no longer a VIE and its financial position is consolidated within NACCO’s financial statements as of June 30, 2020. The consolidation of Camino Real did not materially change the Company’s balance sheet. The results of operations for the six months ended June 30, 2020 are reported under the equity method with income before income taxes reported as Earnings of unconsolidated operations on the Consolidated Statements of Operations.  

The MLMC contract is the only operating coal contract in which the Company is responsible for all operating costs, capital requirements and final mine reclamation; therefore, MLMC is consolidated within NACCO’s financial statements. MLMC sells coal to its customer at a contractually agreed-upon price which adjusts monthly, primarily based on changes in the level of established indices which reflect general U.S. inflation rates. Profitability at MLMC is affected by customer demand for coal, changes in the indices that determine sales price and actual costs incurred. As diesel fuel is heavily weighted among the indices used to determine the coal sales price, the persistence of low diesel fuel prices can negatively affect earnings at MLMC.

MLMC delivers coal to the Red Hills Power Plant in Ackerman, Mississippi. The Red Hills Power Plant supplies electricity to the Tennessee Valley Authority ("TVA") under a long-term Power Purchase Agreement. MLMC’s contract with its customer runs through 2032. TVA’s power portfolio includes coal, nuclear, hydroelectric, natural gas and renewables. The decision of which power plants to dispatch is determined by TVA.

Centennial Natural Resources (“Centennial”), located in Alabama, ceased coal production at the end of 2015. Since 2015, the Company has sold or transferred certain Centennial equipment and mineral reserves. The Company continues to evaluate strategies for the remaining mineral reserves and a dragline, which have no remaining book value. Cash expenditures related to mine reclamation at Centennial will continue until mine reclamation is complete, or ownership of, or responsibility for, the remaining mines is transferred. Centennial is a consolidated entity within the Coal Mining segment as the Company is responsible for carrying costs and final mine reclamation.

The coal reserves at Coteau, Falkirk, Coyote, MLMC and Centennial are owned or controlled by the Company. The coal reserves at all other mines are owned or controlled by the respective mine’s customer.

The Company performs contemporaneous reclamation activities at each mine in the normal course of operations. Under all of the Unconsolidated Subsidiaries’ contracts, the customer has the obligation to fund final mine reclamation activities. Under certain contracts, the Unconsolidated Subsidiary holds the mine permit and is therefore responsible for final mine reclamation activities. To the extent the Unconsolidated Subsidiary performs such final reclamation, it is compensated for providing those services in addition to receiving reimbursement from customers for costs incurred.

The contracts under which certain of the Unconsolidated Subsidiaries operate provide that, under certain conditions, including default, the customer(s) involved may elect or be obligated to acquire the assets (subject to the liabilities) or the capital stock of the Coal Mining subsidiary for an amount effectively equal to book value. The Company does not know of any conditions of default that currently exist.

NAMining Segment

The NAMining segment provides value-added contract mining and other services for producers of aggregates, lithium and other minerals. The segment is a primary platform for the Company’s growth and diversification outside of the coal industry. NAMining provides contract mining services for independently owned mines and quarries, creating value for its customers by performing the mining aspects of its customers’ operations. This allows customers to focus on their areas of expertise: materials handling and processing, product sales and distribution. NAMining operates primarily at limestone quarries in Florida, but is focused on expanding outside of Florida and into mining materials other than limestone. During 2019, the Company entered into a mining agreement to serve as exclusive contract miner for the Thacker Pass lithium project in northern Nevada. NAMining utilizes both fixed price and management fee contract structures.

Minerals Management Segment

The Minerals Management segment promotes the development of the Company’s gas, oil and coal reserves, generating income primarily from royalty-based lease payments from third parties. The Company’s gas, oil and undeveloped coal reserves are located in Ohio (Utica and Marcellus shale natural gas), Louisiana (Haynesville shale and Cotton Valley formation natural gas), Mississippi (coal), Pennsylvania (coal, coalbed methane and Marcellus shale natural gas), Alabama (coal and coalbed methane and natural gas) and North Dakota (coal).

The majority of the Company’s existing reserves were acquired as part of its historical coal mining operations. The Minerals Management segment derives income primarily by entering into contracts with third-party operators, granting them the rights to

19

explore, produce and sell natural resources in exchange for royalty payments based on the lessees' sales of natural gas and, to a lesser extent, oil and coal. Specialized employees in the Minerals Management segment also provide surface and mineral acquisition and lease maintenance services related to Company operations.

The components of the change in revenues and operating profit are discussed below in "Segment Results."

Second Quarter of 2020 Compared with Second Quarter of 2019 and First Six Months of 2020 Compared with First Six Months of 2019

Other expense (income), net

Interest expense increased in the second quarter and the first six months of 2020 compared with the 2019 periods by $0.1 million and $0.3 million, respectively, due to higher average borrowings under NACoal's revolving credit facility.

20

Interest income decreased in the second quarter and the first six months of 2020 compared with the 2019 periods by $0.5 million and $0.6 million, respectively, primarily due to lower interest rates despite a higher invested cash balance.

Income from other unconsolidated affiliates represents the financial results of NoDak. NoDak operated and maintained a coal drying system at a customer’s power plant. The NoDak contract expired on January 31, 2020, resulting in decreases of $0.2 million and $0.4 million, respectively, in Income from other unconsolidated affiliates during the second quarter and the first six months of 2020 compared with the 2019 periods. Income from NoDak was $1.3 million for the year ended December 31, 2019.

Gain on equity securities represents changes in the market price of invested assets reported at fair value. The change in the gains during the second quarter of 2020 and the first six months of 2020 compared with the gains during the 2019 periods was due to higher returns on invested assets during the second quarter of 2020 but lower returns on invested assets in the first quarter of 2020. See Note 6 to the Unaudited Condensed Consolidated Financial Statements for further discussion of equity securities.

Income Taxes

The Company evaluates and updates its estimated annual effective income tax rate on a quarterly basis based on current and forecasted operating results and tax laws. Consequently, based upon the mix and timing of actual earnings compared to projections of earnings between entities that benefit from percentage depletion and those that do not, the effective tax rate may vary quarterly. The quarterly income tax provision is generally comprised of tax expense on income or a benefit on a loss at the most recent estimated annual effective income tax rate, adjusted for the effect of discrete items.

On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act ("CARES Act") was enacted in response to the COVID-19 pandemic. The CARES Act contains numerous income tax provisions, including among other items, temporary changes regarding the prior and future utilization of net operating losses. The CARES Act allows net operating losses incurred in 2018, 2019, and 2020 to be carried back to each of the five preceding taxable years to generate a refund of previously paid income taxes. The 2020 estimated annual effective tax rate includes the benefit of utilizing the current year forecasted tax basis net operating loss that would otherwise be deductible at the current 21% statutory rate to offset taxable income in years that were taxed at a 35% rate. The Company expects to generate a net operating loss in 2020 primarily due to the realization of certain deferred tax assets. The Company is currently assessing aspects of the CARES Act, including the Company’s ability to utilize the extended carryback provisions.

LIQUIDITY AND CAPITAL RESOURCES OF NACCO

Cash Flows

The following tables detail NACCO's changes in cash flow for the six months ended June 30:

	2020			2019			Change
Operating activities:
Net cash (used for) provided by operating activities	$	(12,489	)	$	22,088		$	(34,577	)
Investing activities:
Expenditures for property, plant and equipment	(12,799		)	(5,967		)	(6,832		)
Other	(1,845		)	15			(1,860		)
Net cash used for investing activities	(14,644		)	(5,952		)	(8,692		)
Cash flow before financing activities	$	(27,133	)	$	16,136		$	(43,269	)

The $34.6 million change in net cash (used for) provided by operating activities was primarily due to payments made for deferred compensation and long-term incentive compensation plans and lower net income during the first six months of 2020. In addition, an increase in accounts receivable in the first six months of 2020 compared to a decrease in the first six months of 2019 was partially offset by a reduction in inventory in the first six months of 2020 compared with the 2019 period, both primarily due to higher sales at Coal Mining and NAMining during the first six months of 2020.

The change in net cash used for investing activities was primarily attributable to an increase in expenditures for property, plant and equipment at the NAMining and Coal Mining segments.

21

	2020			2019			Change
Financing activities:
Net additions to long-term debt and revolving credit agreement	$	3,479		$	895		$	2,584
Cash dividends paid	(2,690		)	(2,480		)	(210		)
Purchase of treasury shares	(1,002		)	(1,385		)	383
Net cash used for financing activities	$	(213	)	$	(2,970	)	$	2,757

The change in net cash used for financing activities was primarily due to increased borrowings during the first six months of 2020 compared with the first six months of 2019.

Financing Activities

Financing arrangements are obtained and maintained at the NACoal level. NACCO has not guaranteed any borrowings of NACoal. The borrowing agreements at NACoal allow for the payment to NACCO of dividends and advances under certain circumstances. Dividends (to the extent permitted by NACoal's borrowing agreement) and management fees are the primary sources of cash for NACCO and enable the Company to pay dividends to stockholders.

The Company believes funds available from cash on hand, the NACoal Facility and operating cash flows will provide sufficient liquidity to meet its operating needs and commitments arising during the next twelve months and until the expiration of the NACoal Facility.

NACoal has an unsecured revolving line of credit of up to $150.0 million (the “NACoal Facility”) that expires in August 2022. Borrowings outstanding under the NACoal Facility were $14 million at June 30, 2020. At June 30, 2020, the excess availability under the NACoal Facility was $133.0 million, which reflects a reduction for outstanding letters of credit of $3.1 million.

The NACoal Facility has performance-based pricing, which sets interest rates based upon NACoal achieving various levels of debt to EBITDA ratios, as defined in the NACoal Facility. Borrowings bear interest at a floating rate plus a margin based on the level of debt to EBITDA ratio achieved. The applicable margins, effective June 30, 2020, for base rate and LIBOR loans were 0.75% and 1.75%, respectively. The NACoal Facility has a commitment fee which is based upon achieving various levels of debt to EBITDA ratios. The commitment fee was 0.30% on the unused commitment at June 30, 2020. The weighted average interest rate applicable to the NACoal facility at June 30, 2020 was 1.93% including the floating rate margin.

The NACoal Facility contains restrictive covenants, which require, among other things, NACoal to maintain a maximum debt to EBITDA ratio of 3.00 to 1.00 and an interest coverage ratio of not less than 4.00 to 1.00. The NACoal Facility provides the ability to make loans, dividends and advances to NACCO, with some restrictions based on maintaining a maximum debt to EBITDA ratio of 2.00 to 1.00, or if greater than 2.00 to 1.00, a Fixed Charge Coverage Ratio of 1.10 to 1.00, in conjunction with maintaining unused availability thresholds of borrowing capacity, as defined in the NACoal Facility, of $15.0 million. At June 30, 2020, NACoal was in compliance with all financial covenants in the NACoal Facility.

Capital Expenditures

Expenditures for property, plant and equipment were $12.8 million during the first six months of 2020. Planned expenditures for the remainder of 2020 are expected to be approximately $34 million, primarily consisting of $18 million in the Coal Mining segment, $10 million in the Minerals Management Segment and $6 million in the NAMining segment. Capital expenditures are expected to be funded from internally generated funds and/or bank borrowings.

In the Coal Mining segment, elevated levels of expected capital expenditures through 2021 are primarily related to spending at MLMC as it develops a new mine area. In the Minerals Management segment, capital expenditures in 2020 are primarily for the acquisition of mineral interests and other purchases. In the NAMining segment, capital expenditures in 2020 are primarily for the acquisition, relocation and refurbishment of draglines.

Capital Structure

NACCO's consolidated capital structure is presented below:

	JUNE 30 2020			DECEMBER 31 2019			Change
Cash and cash equivalents	$	95,546		$	122,892		$	(27,346	)
Other net tangible assets	216,637			174,465			42,172
Intangible assets, net	36,333			37,902			(1,569		)
Net assets	348,516			335,259			13,257
Total debt	(28,423		)	(24,943		)	(3,480		)
Bellaire closed mine obligations	(20,822		)	(20,924		)	102
Total equity	$	299,271		$	289,392		$	9,879
Debt to total capitalization	9%			8%			1%

The increase in other net tangible assets was primarily due to payments made for deferred compensation and accrued incentive compensation as well as an increase in accounts receivable at June 30, 2020 compared with December 31, 2019. The increase in other net tangible assets was partially offset by the decrease in cash and cash equivalents.

Contractual Obligations, Contingent Liabilities and Commitments

Since December 31, 2019, there have been no significant changes in the total amount of NACCO's contractual obligations, contingent liabilities or commercial commitments, or the timing of cash flows in accordance with those obligations as reported on page 36 in the Company's Annual Report on Form 10-K for the year ended December 31, 2019. See Note 7 to the Unaudited Condensed Consolidated Financial Statements for a discussion of certain guarantees related to Coyote Creek.

Second Quarter of 2020 Compared with Second Quarter of 2019

Revenues decreased 4.4% in the second quarter of 2020 compared with the second quarter of 2019 due to a reduction in tons delivered. This was partially offset by an increase in the per ton sales price at MLMC. The sales price at MLMC is index-based and includes adjustments for coal quality and reimbursable costs.

The following table identifies the components of change in operating profit for the second quarter of 2020 compared with the second quarter of 2019:

	Operating Profit
2019	$	7,262
Increase (decrease) from:
Selling, general and administrative expenses	492
Gross profit	396
Amortization of intangibles	89
Earnings of unconsolidated operations	(729		)
Net gain on sale of assets	(12		)
2020	$	7,498

Operating profit increased $0.2 million in the second quarter of 2020 compared with the second quarter of 2019 primarily due to a decrease in selling, general and administrative expenses and an increase in gross profit, partially offset by a decrease in earnings of unconsolidated operations. The decrease in selling, general and administrative expenses was primarily attributable to lower employee-related expenses partially offset by an increase in outside service fees. The improvement in gross profit was primarily due to an increase in the profit per ton delivered at MLMC. The increase in profit per ton delivered was primarily due to the increase in the per ton sales price partially offset by an increase in the cost per ton delivered.

The decrease in earnings of unconsolidated operations was mainly due to lower customer demand at Sabine, Bisti and Camino, partially offset by an increase in customer demand at Coyote Creek and Falkirk. Sabine delivers coal to Southwestern Electric Power Company's Henry W. Pirkey Plant. The Pirkey power plant was dispatched at a lower rate during the second quarter of 2020 compared with the second quarter of 2019. The reduction in coal tons delivered at Bisti was due to an extended plant outage during the second quarter of 2020. The reduction in tons delivered at Camino was primarily due to a decrease in customer demand.

First Six Months of 2020 Compared with First Six Months of 2019

Revenues increased 8.1% in the first six months of 2020 compared with the first six months of 2019 due to an increase in MLMC's sales price and tons delivered. The sales price at MLMC is index-based and includes adjustments for coal quality and reimbursable costs. MLMC delivers coal to the Red Hills Power Plant, which supplies electricity to TVA under a long-term Power Purchase Agreement. The decision of which power plants to dispatch is determined by TVA. The Red Hills power plant experienced an increase in dispatch during the first six months of 2020 compared with the first six months of 2019, resulting in the increase in tons delivered.

The following table identifies the components of change in operating profit for the first six months of 2020 compared with the first six months of 2019:

	Operating Profit
2019	$	17,269
Increase (decrease) from:
Earnings of unconsolidated operations	(1,483		)
Gross profit	(776		)
Selling, general and administrative expenses	(256		)
Amortization of intangibles	(41		)
Net gain on sale of assets	(30		)
2020	$	14,683

24

Operating profit decreased $2.6 million in the first six months of 2020 compared with the first six months of 2019 primarily due to a decrease in earnings of unconsolidated operations, a decrease in gross profit and an increase in selling, general and administrative expenses.

The decrease in earnings of unconsolidated operations was mainly due to lower customer demand, primarily at Sabine, Camino and Bisti, partially offset by an increase in customer demand at Coyote Creek and Falkirk. For more information about the unconsolidated operations, see the Second Quarter discussion above.

The decrease in gross profit was primarily due to an increase in the cost per ton delivered at MLMC, including the recognition of a portion of costs previously capitalized into inventory. The increase in selling, general and administrative expenses was primarily attributable to higher outside service fees partially offset by lower employee-related expenses.

Operating profit	$	510	$	6,789	$	4,777	$	18,458

Revenues and operating profit decreased in the three and six months ended June 30, 2020 compared with the 2019 periods. The first half of 2019 included significant royalty income generated by a large number of new gas wells put into commission during 2018 and early 2019. These wells are operated by third parties to extract natural gas from the Company's Ohio Utica shale mineral reserves. Since new wells have high initial production rates and follow a natural decline before settling into relatively stable, long-term production, royalty income in 2020 decreased substantially from 2019 levels. The increase in selling, general and administrative expenses is due to a $0.5 million charge in the second quarter of 2020 to write-off certain leasehold interests.

UNALLOCATED ITEMS AND ELIMINATIONS

FINANCIAL REVIEW

Unallocated Items and Eliminations were as follows for the three and six months ended June 30:

	THREE MONTHS						SIX MONTHS

Operating loss	$	(4,070	)	$	(4,440	)	$	(8,673	)	(9,808	)

Operating loss decreased in the three and six months ended June 30, 2020 compared with the 2019 periods primarily due to lower employee-related expenses.

NACCO Industries, Inc. Outlook

Coal Mining Outlook

In the second half and for the full year of 2020, the Company expects coal deliveries and Coal Mining operating profit to decrease from the respective prior year periods.

In the prior year fourth quarter, the Company recorded a $2.0 million unfavorable adjustment to mine reclamation liabilities at Centennial. Excluding the impact of this item, operating profit in the second half of 2020 is expected to decrease substantially from the second half of 2019. This decrease is a result of an anticipated decrease in earnings at the unconsolidated mining operations due to reduced customer requirements and an expected increase in operating expenses, mainly due to higher professional fees.

In the second half of 2020, earnings at MLMC are expected to be comparable to the second half of 2019. An anticipated improvement in customer demand resulting from an expected increase in the dispatch of the customer's power plant is expected to be offset by an increase in the cost per ton delivered. If customer demand at MLMC decreases from expected levels, it could unfavorably affect the Company's 2020 earnings outlook.

Excluding the unfavorable 2019 mine reclamation adjustment, 2020 full-year operating profit is expected to decrease from 2019 due to a reduction in earnings at the unconsolidated mining operations and the expected increase in operating expenses. Operating expenses are expected to increase moderately for the full year.

27

Changes in dispatch, including changes due to historically low natural gas prices and the continued increase in renewable generation, particularly wind, could reduce customer demand below anticipated levels which would unfavorably affect the Company’s second half and full-year 2020 outlook.

Capital expenditures are expected to be approximately $23 million in 2020. The Company expects high levels of capital expenditures in 2020 and 2021 primarily related to MLMC's development of a new mine area. These capital expenditures will result in an increase in depreciation that will unfavorably affect operating profit in future periods.

On May 7, 2020, Great River Energy ("GRE"), Falkirk Mine's customer and the Company's second largest customer, announced its intent to retire the Coal Creek Station power plant in the second half of 2022 and modify the Spiritwood Station power plant to be fueled by natural gas. GRE is willing to consider opportunities to sell Coal Creek Station, and NACCO is actively engaged in the exploration of options that could, if successful, allow for transfer of ownership of the power plant to one or more third parties, which would preserve jobs at both Coal Creek Station and the Falkirk Mine.

Falkirk Mine is the sole supplier of lignite coal to Coal Creek Station pursuant to a long-term contract under which Falkirk also supplies a moderate amount of lignite coal annually to Spiritwood Station. In 2019, Falkirk contributed approximately $16 million to NACCO’s Earnings from Unconsolidated Operations. The closure of Coal Creek Station will have a material adverse effect on the long-term earnings of NACCO Industries. The terms of the contract between the Company and GRE specify that GRE is responsible for all costs related to mine closure, including but not limited to, final mine reclamation costs, post-retirement medical benefits and pension costs with respect to Falkirk employees.

As mentioned above, the contract between Camino Real and DRCP was unexpectedly terminated effective July 1, 2020. Camino Real delivered 1.5 million tons of coal during 2019. Closure of the mine does not materially impact NACCO’s outlook for 2020. The contract mining agreement between Camino Real and DRCP was previously expected to terminate in 2021.

NAMining Outlook

In the second half and full year of 2020, NAMining expects limestone deliveries to increase modestly from the respective prior year periods.

NAMining expects operating profit in the second half of 2020 to improve over the second half of 2019, but decrease significantly from the first half of 2020. Operating profit is expected to benefit from earnings associated with new limestone mining contracts and favorable changes in the mix of customer requirements. Full-year 2020 operating profit is expected to increase significantly over 2019.

Capital expenditures are expected to be approximately $13 million in 2020, primarily for the acquisition, relocation and refurbishment of draglines.

In 2019, NAMining's subsidiary, Sawtooth Mining, LLC, entered into a mining agreement to serve as the exclusive contract miner for the Thacker Pass lithium project in northern Nevada, owned by Lithium Nevada, Corp., a subsidiary of Lithium Americas Corp. (TSX: LAC) (NYSE: LAC). Lithium Nevada is in the process of securing permits and currently expects to commence construction in 2021 and production of lithium products in 2023.

Minerals Management Outlook

The Minerals Management segment derives income from royalty-based leases under which lessees make payments to the Company based on their sale of natural gas and, to a lesser extent, oil, natural gas liquids and coal, extracted primarily by third parties. The 2019 results included a substantial increase in royalty income, particularly in the first half of 2019, generated by a large number of new gas wells put into commission during 2018 and early 2019. Given expected lower natural gas prices, fewer expected new wells and the natural production decline that occurs early in the life of a well, full-year 2020 royalty income is expected to decrease and be substantially lower than 2019 levels. While royalty income is expected to decrease in the second half of 2020 compared with the second half of 2019, the rate of decrease is expected to be substantially lower than the decrease in the first half of 2020 because prior year income significantly decreased between the first and the second halves of the year. Natural gas pricing declines and reduced business activity due to the COVID-19 pandemic have resulted in higher-than-average natural gas inventory market levels. A sustained decline in natural gas prices could unfavorably affect the Company’s outlook. 

Decline rates for individual wells can vary due to factors like well depth, well length, formation pressure and facility design. In addition, royalty income can fluctuate favorably or unfavorably in response to a number of factors outside of the Company's control, including the number of wells being operated by third parties, fluctuations in commodity prices (primarily natural gas), fluctuations in production rates associated with operator decisions, regulatory risks, the Company's lessees' willingness and

28

ability to incur well-development and other operating costs, and changes in the availability and continuing development of infrastructure. 

Minerals Management capital expenditures are expected to total approximately $11 million in 2020 primarily for the acquisition of mineral interests and other investments.

Consolidated Outlook

NACCO expects a significant decrease in full-year 2020 consolidated net income compared with 2019, primarily due to the substantial decrease in operating profit at Minerals Management in the first half of 2020, the anticipated reduction in earnings at the Coal Mining segment and the absence of $2.7 million pre-tax income associated with a prior India venture recorded in the third quarter of 2019. These items are expected to be partially offset by the recognition of a 2020 tax benefit as a result of the CARES Act and an improvement in earnings at the NAMining segment.

In 2020, cash flow before financing activities is expected to be a use of cash due to significant capital expenditures and payments made in the first half of the year related to deferred compensation and other payroll liabilities. Consolidated capital expenditures are expected to be approximately $47 million in 2020. Capital expenditures were approximately $13 million in the first half of 2020.

Significant uncertainties exist regarding the COVID-19 pandemic, including the extent of economic disruption it may cause in the future. While the Company's operations to date have not been materially affected by the pandemic, future developments, which are highly uncertain and unpredictable, could change the Company's status significantly and rapidly, and could have a material adverse effect on the Company’s operations, supply chain and customers. The extent to which COVID-19 may adversely impact the Company depends on many factors, including but not limited to the extent of new outbreaks as communities reopen, the extent to which additional lockdowns may be needed, the nature of the government public health guidelines and the public's adherence to those guidelines, the success of businesses reopening, and the timing for proven treatments and vaccines for COVID-19. Even after the COVID-19 pandemic has subsided, the Company may experience material adverse effects due to a resulting decline in economic activity. Additionally, concerns over the economic impact of COVID-19 have caused extreme volatility in financial and other capital markets and may continue to adversely impact NACCO's stock price.

One of the Company’s core strategies is to pursue activities which can strengthen the resiliency of its existing coal mining operations. The Company works to drive down coal production costs and maximize efficiencies and operating capacity at mine locations to help customers with management fee contracts be more competitive. This benefits both customers and the Company's Coal Mining segment, as fuel cost is the major driver for power plant dispatch. Increased power plant dispatch drives increased demand for coal by the Coal Mining segment's customers, just as lower dispatch reduces demand.

The Company continues to evaluate opportunities to expand its coal mining business, however opportunities are likely to be very limited. Low natural gas prices and growth in renewable energy sources, such as wind and solar, could continue to unfavorably affect the amount of electricity dispatched from coal-fired power plants. The political and regulatory environment is not generally receptive to development of new coal-fired power generation projects which would create opportunities to build and operate new coal mines. However, the Company does continue to seek out and pursue opportunities where it can apply its management fee business model to replace legacy operators of existing surface coal mining operations in the United States. Outright acquisitions of existing coal mines or mining companies with exposure to fluctuating coal commodity markets, or structures that would create significant leverage, are outside the Company’s area of focus.

The Company is focused on building a strong portfolio of affiliated businesses for diversification. NAMining continues to expand the scope of its business development activities to grow and diversify by targeting potential customers who require a broad range of minerals and materials. NAMining also continues to leverage the Company’s core mining skills to expand the range of contract mining services provided, in addition to providing comprehensive mining services to operate entire mines when appropriate, as is the case at the new lithium project in Nevada.

The Company’s efforts to grow and diversify the Minerals Management segment includes evaluating acquisitions of additional mineral interests or similar investments in the energy industry. The Company's primary initial focus will be on diversifying acquisitions of mineral interests with a balance of near-term cash flow yields and upside potential from future development. During the second quarter of 2020, the Company’s subsidiary, Catapult Mineral Partners, invested $2.0 million to acquire shares of a public company with a diversified portfolio of royalty producing mineral interests as part of this growth and diversification strategy. The recent dramatic downturn in petroleum prices provided an opportunity to make this investment at an attractive market multiple for a company with a conservative financial position, strong earnings potential and attractive historical dividend yield.

29

Mitigation Resources of North America^® was formed to create and sell stream and wetland mitigation credits and provide services to those engaged in permittee-responsible mitigation. This business has achieved several early successes and is positioned for additional growth.

The Company is leveraging its core mining skills to develop a strong and diverse portfolio of service-based businesses operating in the mining and natural resources industries. The Company is also committed to maintaining a conservative capital structure while it grows and diversifies without unnecessary risk. Ultimately, diversified strategic growth is the key to increasing free cash flow available to continue to re-invest in and expand the businesses. The Company also continues to maintain the highest levels of customer service and operational excellence, with an unwavering focus on safety and environmental stewardship.

Item 1A    Risk Factors

During the quarter ended June 30, 2020, there have been no material changes to the risk factors previously disclosed in the Company's Annual Report on Form 10-K for the year ended December 31, 2019, except as follows:

The Company’s results of operations, financial condition, cash flows and stock price could be adversely affected by pandemics, epidemics or other public health emergencies, such as the recent outbreak of COVID-19.

The Company’s results of operations, financial condition, cash flows and stock price could be adversely affected by pandemics, epidemics or other public health emergencies, such as the global outbreak of COVID-19. The COVID-19 pandemic resulted in governments around the world implementing stringent measures to help control the spread of the virus, including quarantines, "shelter in place" and "stay at home" orders, travel restrictions, business curtailments, school closures, and other measures.

The Company has continued to operate as an essential business because it supports critical infrastructure industries, as defined by the U.S. Department of Homeland Security. Although the Company has continued to operate facilities consistent with federal guidelines and state and local orders, the ongoing COVID-19 pandemic and the preventive or protective actions taken by governmental authorities may have a material adverse effect on the Company’s operations, work force, supply chain or customers, including business shutdowns or disruptions. The extent to which COVID-19 may adversely impact the Company's businesses depends on future developments, which are highly uncertain and unpredictable, including the extent of new outbreaks as communities reopen, the extent to which additional lockdowns may be needed, the nature of the government public health guidelines and the public's adherence to those guidelines, the success of businesses reopening, and the timing for proven treatments and vaccines for COVID-19. Any resulting financial impact cannot reasonably be estimated at this time, but could have a material adverse effect on the Company’s financial condition, cash flows and results of operations.

Even after the COVID-19 pandemic has subsided, the Company may experience material adverse effects due to a decline in economic activity. Additionally, concerns over the economic impact of COVID-19 have caused extreme volatility in financial and other capital markets which has and may continue to adversely impact NACCO's stock price.

Termination of or default under long-term mining contracts could materially reduce the Company's profitability.

Substantially all of the Coal Mining segment's profits are derived from long-term mining contracts. Although the Company has long-term contracts, numerous political and regulatory authorities, along with well-funded environmental activist groups, are devoting substantial resources to anti-coal activities to minimize or eliminate the use of coal as a source of electricity generation. As a result of such activities, the Coal Mining segment's customers could prematurely retire certain coal-fired generating units. Any customers' premature plant closure could have a material adverse effect on the Company’s business, financial condition and results of operations.

On May 7, 2020, Great River Energy ("GRE"), Falkirk Mine's customer, and the Company's second largest customer, announced its intent to retire the Coal Creek Station power plant in the second half of 2022 and modify the Spiritwood Station power plant to be fueled by natural gas.

Falkirk Mine is the sole supplier of lignite coal to Coal Creek Station pursuant to a long-term contract under which Falkirk also supplies approximately 0.3 million tons of lignite coal per year to Spiritwood Station. Falkirk has approximately 480 employees, and, in 2019, delivered a total of 7.4 million tons of lignite coal and contributed approximately $16 million to NACCO’s Earnings from Unconsolidated Operations. The closure of Coal Creek Station would have a material adverse effect on the long-term earnings of NACCO. The terms of the contract between the Company and GRE specify that GRE is responsible for all costs related to mine closure, including but not limited to final mine reclamation costs, post-retirement medical benefits and pension costs with respect to Falkirk employees.

Also noted in GRE’s announcement is their plan to negotiate an agreement to terminate their steam and water supply contract with Blue Flint, an ethanol biorefinery fueled by process steam from Coal Creek Station. Blue Flint’s owner,

33

Midwest AgEnergy, is considering using the contract termination payment from Great River Energy to reinvest in an economical alternate source for its process heat. NACCO has a $5.0 million investment in Midwest AgEnergy. If Midwest AgEnergy is unable to find an economical alternate source for its process heat, the Company’s investment could become impaired.

State implementation of the EPA’s Regional Haze Rule (“RHR”) could require Coyote Creek’s customers to incur significant new costs at the Coyote Station power plant, which could, dependent on determinations by state regulatory commissions on approval to recover such costs from Coyote Creek’s customer’s customers, negatively impact Coyote Creek’s customers’ net income, financial position and cash flows. The Company understands that the North Dakota Department of Environmental Quality (“NDDEQ”) intends to require sources subject to RHR Round 2 reasonable progress determinations, including Coyote Station, to undertake emissions control measures. If NDDEQ requires significant emissions controls at Coyote Station by December 31, 2028, it may not be economically feasible for Coyote Creek's customers to invest in such equipment and an early retirement of Coyote Station and the Coyote Creek mine could be necessary. NDDEQ’s state implementation plan is due to be submitted to the EPA by July 2021. The Company expects the NDDEQ to begin drafting preliminary control scenarios for regional visibility modeling in the first half of 2020 and a state implementation plan later in 2020.

Under certain circumstances of default or termination of Coyote Creek’s Lignite Sales Agreement (“LSA”), the Company would be obligated for payment of a "make-whole" amount to Coyote Creek’s third-party lenders. The “make-whole” amount is based on the excess, if any, of the discounted value of the remaining scheduled debt payments over the principal amount. In addition, in the event Coyote Creek’s LSA is terminated on or after January 1, 2024 by Coyote Creek’s customers, the Company is obligated to purchase Coyote Creek’s dragline and rolling stock for the then net book value of those assets. Any decision by Coyote Creek’s customers to reduce operations or prematurely close the Coyote mine would have a material adverse effect on the Company’s results of operations, financial position and cash flows.

Mississippi Lignite Mining Company ("MLMC") is subject to risks associated with its capital investment, operating and equipment costs, growing use of alternative power generation that competes with coal-fired power generation, changes in customer demand and inflationary adjustments.

The profitability of MLMC is subject to the risk of loss of investment in this operation, increases in the cost of mining, changes in customer demand, growing competition from alternative power generation that competes with coal-fired generation and the emergence of adverse mining conditions. At MLMC, the costs of mining operations are not reimbursed by MLMC's customer. As such, increased costs at MLMC or decreased revenues could materially reduce the Company's profitability. Any reduction in customer demand at MLMC, including reductions related to reduced mechanical availability of the customer’s power plant, would adversely affect the Company's operating results and could result in significant impairments. In addition, MLMC sells lignite at contractually agreed upon prices which are subject to changes in the level of established indices over time. The price of diesel fuel is heavily-weighted among these indices. As such, a substantial decline in diesel prices could materially reduce MLMC's profitability, as the decline in revenue will only be partially offset by the effect of lower diesel prices on production costs.

MLMC delivers coal to the Red Hills Power Plant in Ackerman, Mississippi. The Red Hills Power Plant supplies electricity to TVA under a long-term PPA. MLMC’s contract with its customer runs through 2032. TVA’s power portfolio includes coal, nuclear, hydroelectric, natural gas and renewables. In 2019, TVA published its updated Integrated Resource Plan ("IRP"). The IRP indicates TVA plans to increase its reliance on solar power. A decrease in the number of days TVA dispatches the Red Hills Power Plant would reduce MLMC's customer's demand for coal. The decision of which power plants to dispatch is determined by TVA. TVA has dispatched Red Hills Power Plant at a lower rate in the last two years than in prior years.

Choctaw Generation Limited Partnership ("CGLP") leases the Red Hills Power Plant from a Southern Company subsidiary pursuant to a leveraged lease arrangement. The ability of the lessee to make required payments to the Southern Company subsidiary is dependent on the operational performance of the Red Hills Power Plant. Southern Company recently publicly disclosed that while all CGLP lease payments have been paid in full through June 30, 2020, operational and other risks have resulted in cash liquidity challenges at the Red Hills Power Plant, and based on current forecasts of energy prices in the years following the expiration of the PPA in 2032, concerns exist regarding the lessee's ability to make the remaining semi-annual lease payments through the end of the lease term in 2047. During the fourth quarter of 2019, Southern Company concluded that it was no longer probable that all of the payments would be received over the term of the lease and therefore recognized an impairment charge to reduce the value of the lease investment. During the second quarter 2020, Southern Company revised the estimated cash flows to be received under the leveraged lease which resulted in a full impairment of the lease investment. If any future lease payment is not paid

34

in full, the Southern Company subsidiary may be unable to make its corresponding payment to the holders of the underlying non-recourse debt related to the Red Hills Power Plant. Failure to make the required payment to the debtholders could represent an event of default that would give the debtholders the right to foreclose on, and take ownership of, the Red Hills Power Plant from the Southern Company subsidiary. A foreclosure of the Red Hills Power Plant could have a material adverse effect on MLMC's financial condition, results of operations and cash flows.

Similar to the Company's unconsolidated mines, all production costs at MLMC are capitalized into inventory and recognized in cost of sales as tons are delivered. In periods of limited or no deliveries, MLMC may be required to reduce its inventory carrying value using the lower of cost or net realizable value approach, which could adversely affect MLMC’s results of operations.

Changes in customer demand for any reason, including, but not limited to, reduced mechanical availability of the customer’s power plant, dispatch of power generated by other energy sources ahead of coal, fluctuations in demand due to unanticipated weather conditions, regulations or comparable policies which may promote planned and unplanned outages at the Red Hills Power Plant, economic conditions, including an economic slowdown and a corresponding decline in the use of electricity, governmental regulations and inflationary adjustments could have a material adverse effect on MLMC's financial condition, results of operations and cash flows.

Exhibit 95

MINE SAFETY DISCLOSURES

NACCO Industries, Inc. and its wholly owned subsidiaries (the “Company”) believes that The North American Coal Corporation and its affiliated coal companies (collectively, “NACoal”) is an industry leader in safety. NACoal has health and safety programs in place that include extensive employee training, accident prevention, workplace inspection, emergency response, accident investigation, regulatory compliance and program auditing. The objectives for NACoal's programs are to eliminate workplace incidents, comply with all mining-related regulations and provide support for both regulators and the industry to improve mine safety.

Under the Dodd-Frank Wall Street Reform and Consumer Protection Act, each operator of a coal or other mine is required to include certain mine safety results in its periodic reports filed with the Securities and Exchange Commission. The operation of NACoal's mines is subject to regulation by the Federal Mine Safety and Health Administration ("MSHA") under the Federal Mine Safety and Health Act of 1977 (the "Mine Act"). MSHA inspects NACoal's mines on a regular basis and issues various citations and orders when it believes a violation has occurred under the Mine Act. The Company has presented information below regarding certain mining safety and health matters for NACoal's mining operations for the quarter ended June 30, 2020. In evaluating this information, consideration should be given to factors such as: (i) the number of citations and orders will vary depending on the size of the mine, (ii) the number of citations issued will vary from inspector to inspector and from mine to mine, and (iii) citations and orders can be contested and appealed, and in that process, are often reduced in severity and amount, and are sometimes vacated.

During the quarter ended June 30, 2020, neither NACoal's current mining operations nor Bellaire's closed mines: (i) were assessed any Mine Act section 104(b) orders for alleged failure to totally abate the subject matter of a Mine Act section 104(a) citation within the period specified in the citation; (ii) were assessed any Mine Act section 104(d) citations or orders for an alleged unwarrantable failure (i.e., aggravated conduct constituting more than ordinary negligence) to comply with a mining safety standard or regulation; (iii) were assessed any Mine Act section 110(b)(2) penalties for failure to correct the subject matter of a Mine Act section 104(a) citation within the specified time period, which failure was deemed flagrant (i.e., reckless or repeated failure to make reasonable efforts to eliminate a known violation that substantially and proximately caused, or reasonably could have been expected to cause, death or serious bodily injury); (iv) received any Mine Act section 107(a) imminent danger orders to immediately remove miners; or (v) received any MSHA written notices under Mine Act section 104(e) of a pattern of violation of mandatory health or safety standards or of the potential to have such a pattern. In addition, there were no mining-related fatalities at NACoal's mining operations or Centennial or Bellaire's closed mines during the quarter ended June 30, 2020.

The following table sets forth the total number of specific citations and orders, the total dollar value of the proposed civil penalty assessments that were issued by MSHA, the total number of legal actions initiated and resolved before the Federal Mine Safety and Health Review Commission ("FMSHRC") during the quarter ended June 30, 2020, and the total number of legal actions pending before the FMSHRC at June 30, 2020, pursuant to the Mine Act, by individual mine at NACoal:

(1) Bellaire's, Centennial's and Liberty's closed mines are not included in the table above and did not receive any of the indicated citations.

(2) Mine Act section 104(a) significant and substantial citations are for alleged violations of a mining safety standard or regulation where there exists a reasonable likelihood that the hazard contributed to or will result in an injury or illness of a reasonably serious nature. The Newberry Quarry citation was reduced to non-significant and non-substantial after an agreement was reached with MSHA.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Nature of Operations and Basis of Presentation

Nature of Operations and Basis of Presentation

The accompanying Unaudited Condensed Consolidated Financial Statements include the accounts of NACCO Industries, Inc.^® (“NACCO”) and its wholly owned subsidiaries (collectively, “NACCO Industries, Inc. and Subsidiaries” or the “Company”). Intercompany accounts and transactions are eliminated in consolidation. NACCO is the public holding company for The North American Coal Corporation^® ("NACoal"). The Company has three operating segments: Coal Mining, North American Mining (“NAMining”) and Minerals Management. The Company also has unallocated items not directly attributable to a reportable segment. See Note 9 to the Unaudited Condensed Consolidated Financial Statements for further discussion of segment reporting.

The Company’s operating segments are further described below:

Coal Mining Segment

During the six months ended June 30, 2020, the operating coal mines are: Bisti Fuels LLC (“Bisti”), Caddo Creek Resources Company, LLC (“Caddo Creek”), Camino Real Fuels, LLC (“Camino Real”), The Coteau Properties Company (“Coteau”), Coyote Creek Mining Company, LLC (“Coyote Creek”), Demery Resources Company, LLC (“Demery”), The Falkirk Mining Company (“Falkirk”), Mississippi Lignite Mining Company (“MLMC”) and The Sabine Mining Company (“Sabine”).

The contract mining agreement between Camino Real and its customer, Dos Republicas Coal Partnership (“DRCP”), terminated effective July 1, 2020 as a result of the unexpected termination by Comisión Federal de Electricidad (“CFE”) of its coal supply contract with an affiliate of DRCP. The termination of the contract between CFE and DRCP eliminated DRCP’s need for coal from Camino Real's Eagle Pass Mine, and will result in mine closure.

Camino Real issued a Notice of Payment Default on June 17, 2020. During the third quarter of 2020, the Company received certain inventory as well as a securitized note in settlement of the outstanding receivable balance as of June 30, 2020 and additional costs incurred through the July 9, 2020 mine closure date. Mine reclamation is the responsibility of DRCP. Camino Real has no legal obligation to perform mine reclamation but is in negotiations with DRCP to potentially perform mine reclamation activities under a new contractual arrangement. Closure of the mine does not materially impact NACCO’s outlook for 2020. The contract mining agreement between Camino Real and DRCP was previously expected to terminate in 2021.

As of June 30, 2020, all of the Liberty Fuels Company, LLC mine areas have been reclaimed and final mine reclamation activities, primarily monitoring, will continue until final bond release.

At all operating coal mines other than MLMC, the Company is paid a management fee per ton of coal or heating unit (MMBtu) delivered. Each contract specifies the indices and mechanics by which fees change over time, generally in line with broad measures of U.S. inflation. The customers are responsible for funding all mine operating costs, including final mine reclamation, and directly or indirectly providing all of the capital required to build and operate the mine. This contract structure eliminates exposure to spot coal market price fluctuations while providing steady income and cash flow with minimal capital investment. Other than at Coyote Creek, debt financing provided by or supported by the customers is without recourse to NACCO and NACoal. See Note 7 for further discussion of Coyote Creek's guarantees.

All operating coal mines other than MLMC meet the definition of a variable interest entity (“VIE”). In each case, NACCO is not the primary beneficiary of the VIE as it does not exercise financial control; therefore, NACCO does not consolidate the results of these operations within its financial statements. Instead, these contracts are accounted for as equity method investments. The income before income taxes associated with these VIE's is reported as Earnings of unconsolidated operations on the Consolidated Statements of Operations and the Company’s investment is reported on the line Investments in unconsolidated subsidiaries in the Consolidated Balance Sheets. The mines that meet the definition of a VIE are referred to collectively as the “Unconsolidated Subsidiaries.” For tax purposes, the Unconsolidated Subsidiaries are included within the NACCO consolidated U.S. tax return; therefore, the income tax expense line on the Consolidated Statements of Operations includes income taxes related to these entities. All of the Unconsolidated Subsidiaries are accounted for under the equity method. See Note 7 for further discussion.

Camino Real previously met the definition of a variable interest entity of which the Company was not the primary beneficiary and therefore NACCO did not consolidate Camino Real’s results of operations within its financial statements.

The Notice of Payment Default and subsequent termination of the contract mining agreement resulted in a reconsideration event, which required reassessment of the Company’s VIE conclusion. As a result of this reconsideration, Camino Real is no longer a VIE and its financial position is consolidated within NACCO’s financial statements as of June 30, 2020. The consolidation of Camino Real did not materially change the Company’s balance sheet. The results of operations for the six months ended June 30, 2020 are reported under the equity method with income before income taxes reported as Earnings of unconsolidated operations on the Consolidated Statements of Operations.  

The MLMC contract is the only operating coal contract in which the Company is responsible for all operating costs, capital requirements and final mine reclamation; therefore, MLMC is consolidated within NACCO’s financial statements. MLMC sells coal to its customer at a contractually agreed-upon price which adjusts monthly, primarily based on changes in the level of established indices which reflect general U.S. inflation rates.

Centennial Natural Resources (“Centennial”), located in Alabama, ceased coal production at the end of 2015. Since 2015, the Company has sold or transferred certain Centennial equipment and mineral reserves. The Company continues to evaluate strategies for the remaining mineral reserves and a dragline, which have no remaining book value. Cash expenditures related to mine reclamation at Centennial will continue until mine reclamation is complete, or ownership of, or responsibility for, the remaining mines is transferred. Centennial is a consolidated entity within the Coal Mining segment as the Company is responsible for carrying costs and final mine reclamation.

NAMining Segment

The NAMining segment provides value-added contract mining and other services for producers of aggregates, lithium and other minerals. The segment is a primary platform for the Company’s growth and diversification outside of the coal industry. NAMining provides contract mining services for independently owned mines and quarries, creating value for its customers by performing the mining aspects of its customers’ operations. This allows customers to focus on their areas of expertise: materials handling and processing, product sales and distribution. NAMining operates primarily at limestone quarries in Florida, but is focused on expanding outside of Florida and into mining materials other than limestone. During 2019, the Company entered into a mining agreement to serve as exclusive contract miner for the Thacker Pass lithium project in northern Nevada. NAMining utilizes both fixed price and cost plus management fee contract structures. Certain of the entities within NAMining segment are VIEs and are accounted for under the equity method as Unconsolidated Subsidiaries. See Note 7 for further discussion.

Minerals Management Segment

The Minerals Management segment promotes the development of the Company’s gas, oil and coal reserves, generating income primarily from royalty-based lease payments from third parties. The Company’s gas, oil and undeveloped coal reserves are located in Ohio (Utica and Marcellus shale natural gas), Louisiana (Haynesville shale and Cotton Valley formation natural gas), Mississippi (coal), Pennsylvania (coal, coalbed methane and Marcellus shale natural gas), Alabama (coal and coalbed methane and natural gas) and North Dakota (coal).

The majority of the Company’s existing reserves were acquired as part of its historical coal mining operations. The Minerals Management segment derives income primarily by entering into contracts with third-party operators, granting them the rights to explore, produce and sell natural resources in exchange for royalty payments based on the lessees' sales of natural gas and, to a lesser extent, oil and coal. Specialized employees in the Minerals Management segment also provide surface and mineral acquisition and lease maintenance services related to Company operations.

Basis of Presentation: These financial statements have been prepared in accordance with U.S. generally accepted accounting principles ("U.S. GAAP") for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X.

Revenue from Contract with Customer [Abstract]

Revenue Recognition

Revenue Recognition

Nature of Performance Obligations

At contract inception, the Company assesses the goods and services promised in its contracts with customers and identifies a performance obligation for each promised good or service that is distinct. To identify the performance obligations, the Company considers all of the goods or services promised in the contract regardless of whether they are explicitly stated or are implied by customary business practices.

Each mine or mine area has a contract with its respective customer that represents a contract under ASC 606. For its consolidated entities, the Company’s performance obligations vary by contract and consist of the following:

At MLMC, each MMBtu delivered during the production period is considered a separate performance obligation. Revenue is recognized at the point in time that control of each MMBtu of lignite transfers to the customer. Fluctuations in revenue from period to period generally result from changes in customer demand.

At NAMining entities, the management service to oversee the operation of the equipment and delivery of limestone is the performance obligation accounted for as a series. Performance momentarily creates an asset that the customer simultaneously receives and consumes; therefore, control is transferred to the customer over time. Consistent with the conclusion that the customer simultaneously receives and consumes the benefits provided, an input-based measure of progress is appropriate. As each month of service is completed, revenue is recognized for the amount of actual costs incurred, plus the management fee and the general and administrative fee (as applicable). Fluctuations in revenue from period to period result from changes in customer demand and variances in reimbursable costs primarily due to increases and decreases in activity levels on individual contracts.

The Company enters into royalty contracts which grant the right to explore, develop, produce and sell minerals controlled by the Company. These arrangements result in the transfer of mineral rights for a period of time; however, no rights to the actual land are granted other than access for purposes of exploration, development, production and sales. The mineral rights revert back to the Company at the expiration of the contract.

Under these royalty contracts, granting exclusive right, title, and interest in and to minerals, if any, is the performance obligation. The performance obligation under these contracts represents a series of distinct goods or services whereby each day of access that is provided is distinct. The transaction price consists of a variable sales-based royalty and, in certain arrangements, a fixed component in the form of an up-front lease bonus payment. As the amount of consideration the Company will ultimately be entitled to is entirely susceptible to factors outside its control, the entire amount of variable consideration is constrained at contract inception. The fixed portion of the transaction price will be recognized over the primary term of the contract, which is generally five years.

Significant Judgments

The Company’s contracts with its customers contain different types of variable consideration including, but not limited to, management fees that adjust based on coal volumes or MMBtu delivered or limestone yards, however, the terms of these variable payments relate specifically to the Company's efforts to satisfy one or more, but not all of, the performance obligations (or to a specific outcome from satisfying the performance obligations), in the contract. Therefore, the Company allocates each variable payment (and subsequent changes to that payment) entirely to the specific performance obligation to which it relates. Management fees, as well as general and administrative fees, are also adjusted based on changes in specified indices (e.g., CPI) to compensate for general inflation changes. Index adjustments, if applicable, are effective prospectively. Certain contracts include reimbursement of actual costs incurred.

Disaggregation of Revenue

In accordance with ASC 606-10-50, the Company disaggregates revenue from contracts with customers into major goods and service lines and timing of transfer of goods and services. The Company determined that disaggregating revenue into these categories achieves the disclosure objective of depicting how the nature, amount, timing, and uncertainty of revenue and cash flows are affected by economic factors. The Company’s business consists of the Coal Mining, NAMining and Minerals Management segments as well as Unallocated Items. See Note 9 to the Unaudited Condensed Consolidated Financial Statements for further discussion of segment reporting.

The following table disaggregates revenue by major sources:

	THREE MONTHS ENDED						SIX MONTHS ENDED
	JUNE 30						JUNE 30
Major Goods/Service Lines	2020			2019			2020			2019

Goods transferred at a point in time	$	20,976		$	21,879		$	41,260		$	37,964
Services transferred over time	14,379			19,473			31,739			43,485
Total revenues	$	35,355		$	41,352		$	72,999		$	81,449

Contract Balances

The opening and closing balances of the Company’s current and long-term contract liabilities and receivables are as follows:

	Contract balances
	Trade accounts receivable, net		Contract liability (current)			Contract liability (long-term)
Balance, January 1, 2020	$	15,444	$	944		$	2,153
Balance, June 30, 2020	20,335		941			1,683
Increase (decrease)	$	4,891	$	(3	)	$	(470	)

As described above, the Company enters into royalty contracts that grant exclusive right, title, and interest in and to minerals. The transaction price consists of a variable sales-based royalty and, in certain arrangements, a fixed component in the form of an up-front lease bonus payment. The timing of the payment of the fixed portion of the transaction price is upfront, however, the performance obligation is satisfied over the primary term of the contract, which is generally five years. Therefore, at the time any such up-front payment is received, a contract liability is recorded which represents deferred revenue. The difference between the opening and closing balance of this contract liability, which is shown above, primarily results from the difference between new lease bonus payments received and amortization of up-front lease bonus payments received in previous periods.

The amount of revenue recognized in the three months ended June 30, 2020 and June 30, 2019 that was included in the opening contract liability was $0.3 million and $0.2 million, respectively. The amount of revenue recognized in the six months ended June 30, 2020 and June 30, 2019 that was included in the opening contract liability was $0.5 million and $0.4 million, respectively. This revenue consists of up-front lease bonus payments received under royalty contracts that are recognized over the primary term of the royalty contracts, which are generally five years. The Company expects to recognize an additional $0.5 million in the remainder of 2020, $0.9 million in 2021, $0.7 million in 2022, $0.3 million in 2023, and $0.1 million in 2024 related to the contract liability remaining at June 30, 2020. The difference between the opening and closing balances of the Company’s accounts receivable and contract liabilities results from the timing difference between the Company’s performance and the customer’s payment. Contracts with payments in arrears are recognized as receivables.

The Company has no contract assets recognized from the costs to obtain or fulfill a contract with a customer.

Leases

NACCO adopted ASU 2016-02, Leases (Topic 842), on January 1, 2019. The most significant effect to the Unaudited Condensed Consolidated Balance Sheets relates to the recognition of new right-of-use assets and lease liabilities for operating leases of real estate, mining and other equipment that expire at various dates through 2031. The majority of the Company's leases are operating leases. See the table below for further information on the balances included in the Unaudited Condensed Consolidated Balance Sheets. Several leases include renewal or fair value purchase options, which are not recognized on the Unaudited Condensed Consolidated Balance Sheets. The Company's lease agreements do not contain lease payments that depend on an index or a rate, as such, minimum lease payments do not include variable lease payments.

Leased assets and liabilities include the following:

As most of the Company's leases do not provide an implicit rate, the Company determines the incremental borrowing rate based on the information available at the lease commencement date in determining the present value of lease payments. The Company considers its credit rating and the current economic environment in determining this collateralized rate.

The assumptions used in accounting for ASC 842 were as follows:

Stockholders' Equity

Stockholders' Equity

Stock Repurchase Program: On November 6, 2019, the Company's Board of Directors approved a stock purchase program ("2019 Stock Repurchase Program") providing for the purchase of up to $25 million of the Company's outstanding Class A Common Stock through December 31, 2021. NACCO's previous repurchase program ("2018 Stock Repurchase Program") would have expired on December 31, 2019 but was terminated and replaced by the 2019 Stock Repurchase Program. As a result of the uncertainty surrounding the COVID-19 pandemic, the Company suspended repurchasing shares under the 2019 Stock Repurchase Program in March 2020. Prior to the decision to cease share repurchases, the Company repurchased 32,286 shares of Class A Common Stock under the 2019 Stock Repurchase Program for an aggregate purchase price of $1.0 million during the six months ended June 30, 2020. During the three and six months ended June 30, 2019, the Company repurchased 2,230 and 38,524 shares, respectively, of Class A Common Stock under the 2018 Stock Repurchase Program for an aggregate purchase price of $0.1 million and $1.4 million, respectively.

The timing and amount of any repurchases under the 2019 Stock Repurchase Program are determined at the discretion of the Company's management based on a number of factors, including the availability of capital, other capital allocation alternatives, market conditions for the Company's Class A Common Stock and other legal and contractual restrictions. The 2019 Stock

Repurchase Program does not require the Company to acquire any specific number of shares and may be modified, suspended, extended or terminated by the Company without prior notice and may be executed through open market purchases, privately negotiated transactions or otherwise. All or part of the repurchases under the 2019 Stock Repurchase Program may be implemented under a Rule 10b5-1 trading plan, which would allow repurchases under pre-set terms at times when the Company might otherwise be restricted from doing so under applicable securities laws.

Bellaire Corporation (“Bellaire”) is a non-operating subsidiary of the Company with legacy liabilities relating to closed mining operations, primarily former Eastern U.S. underground coal mining operations. Prior to 2019, Bellaire established a $5.0 million mine water treatment trust (the "Mine Water Treatment Trust") to provide a financial assurance mechanism to assure the long-term treatment of post-mining discharge. Bellaire's Mine Water Treatment Trust invests in equity securities that are reported at fair value based upon quoted market prices in active markets for identical assets; therefore, they are classified as Level 1 within the fair value hierarchy. The Company recognized a gain of $1.1 million and a loss of $0.1 million in the three and six months ended June 30, 2020, respectively, and a gain of $0.3 million and $1.0 million in the three and six months ended June 30, 2019, respectively, related to the Mine Water Treatment Trust.

During the second quarter of 2020, the Company invested $2.0 million in equity securities of a public company with a diversified portfolio of royalty producing mineral interests. The investment is reported at fair value based upon quoted market prices in active markets for identical assets; therefore, it is classified as Level 1 within the fair value hierarchy. The Company recognized a gain of $0.4 million in both the three and six months ended June 30, 2020 related to the investment in these equity securities.

The gains and losses related to equity securities are reported on the line Gain on equity securities in the Other (income) expense section of the Unaudited Condensed Consolidated Statements of Operations.

There were no transfers into or out of Levels 1, 2 or 3 during the three and six months ended June 30, 2020 and 2019.

Unconsolidated SubsidiarieS

Equity Method Investments and Joint Ventures [Abstract]

Unconsolidated Subsidiaries

Unconsolidated Subsidiaries

Each of NACoal's wholly owned Unconsolidated Subsidiaries, within the Coal Mining and NAMining segments, meet the definition of a VIE. The Unconsolidated Subsidiaries are capitalized primarily with debt financing provided by or supported by their respective customers, and other than at Coyote Creek, without recourse to NACCO and NACoal. Although NACoal owns 100% of the equity and manages the daily operations of the Unconsolidated Subsidiaries, the Company has determined that the equity capital provided by NACoal is not sufficient to adequately finance the ongoing activities or absorb any expected losses without additional support from the customers. The customers have a controlling financial interest and have the power to direct the activities that most significantly affect the economic performance of the entities. As a result, the Company is not the primary beneficiary and therefore does not consolidate these entities' financial positions or results of operations. See Note 1 for a discussion of these entities.

The Investment in the unconsolidated subsidiaries and related tax positions totaled $25.3 million and $24.6 million at June 30, 2020 and December 31, 2019, respectively. The Company's maximum risk of loss relating to these entities is limited to its invested capital, which was $5.3 million and $5.0 million at June 30, 2020 and December 31, 2019, respectively.

NACoal is a party to certain guarantees related to Coyote Creek. Under certain circumstances of default or termination of Coyote Creek’s Lignite Sales Agreement (“LSA”), NACoal would be obligated for payment of a "make-whole" amount to Coyote Creek’s third-party lenders. The “make-whole” amount is based on the excess, if any, of the discounted value of the remaining scheduled debt payments over the principal amount. In addition, in the event Coyote Creek’s LSA is terminated on or after January 1, 2024 by Coyote Creek’s customers, NACoal is obligated to purchase Coyote Creek’s dragline and rolling stock for the then net book value of those assets. To date, no payments have been required from NACoal since the inception of these guarantees. The Company believes that the likelihood NACoal would be required to perform under the guarantees is remote, and no amounts related to these guarantees have been recorded.

Summarized financial information for the Unconsolidated Subsidiaries is as follows:

Commitments and Contingencies Disclosure [Abstract]

Contingencies

Contingencies

Various legal and regulatory proceedings and claims have been or may be asserted against NACCO and certain subsidiaries relating to the conduct of their businesses. These proceedings and claims are incidental to the ordinary course of business of the Company. Management believes that it has meritorious defenses and will vigorously defend the Company in these actions. Any costs that management estimates will be paid as a result of these claims are accrued when the liability is considered probable and the amount can be reasonably estimated.  If a range of amounts can be reasonably estimated and no amount within the range is a better estimate than any other amount, then the minimum of the range is accrued. The Company does not accrue liabilities when the likelihood that the liability has been incurred is probable but the amount cannot be reasonably estimated or when the liability is believed to be only reasonably possible or remote. For contingencies where an unfavorable outcome is probable or reasonably possible and which are material, the Company discloses the nature of the contingency and, in some circumstances, an estimate of the possible loss. 

These matters are subject to inherent uncertainties, and unfavorable rulings could occur. If an unfavorable ruling were to occur, there exists the possibility of an adverse impact on the Company’s financial position, results of operations and cash flows of the period in which the ruling occurs, or in future periods.

Segment Reporting [Abstract]

Business Segments

Business Segments

The Company's operating segments are: (i) Coal Mining, (ii) NAMining and (iii) Minerals Management. While the Company continues to pursue opportunities to add new coal mining operations to the Coal Mining segment, the NAMining segment serves as the platform for pursuing non-coal mining projects and the Minerals Management segment promotes the development of the Company's gas, oil and coal reserves.

The Company determines its reportable segments by first identifying its operating segments, and then by assessing whether any components of these segments constitute a business for which discrete financial information is available and where segment management regularly reviews the operating results of that component. The Company’s Chief Operating Decision Maker utilizes operating profit to evaluate segment performance and allocate resources.

The Company also has unallocated items not directly attributable to a reportable segment which are not included as part of the measurement of segment operating profit, primarily administrative costs related to public company reporting requirements, the financial results of the Company’s mitigation banking business, Mitigation Resources of North America^® (“MRNA”), and Bellaire. MRNA generates and sells stream and wetland mitigation credits (known as mitigation banking) and provides services to those engaged in permittee-responsible stream and wetland mitigation. Bellaire manages the Company’s long-term liabilities related to former Eastern U.S. underground mining activities. Transactions between segments are accounted for as third-party arrangements for purposes of presenting segment results of operations and are eliminated in consolidation.

As of January 1, 2020, the Company retrospectively changed its computation of segment operating profit to reclassify certain expenses, primarily related to executive and board compensation. These expenses are now included in unallocated items. The change in segment reporting reflected a decision to evaluate the financial performance of the Company’s segments excluding executive and board compensation. All prior period segment information has been reclassified to conform to the new presentation. This segment reporting change has no impact on consolidated operating results.

All financial statement line items below operating profit (other income including interest expense and interest income, the provision for income taxes and net income) are presented and discussed within this Form 10-Q on a consolidated basis. Included within other income on the line Income from other unconsolidated affiliates within the Unaudited Condensed Consolidated Statements of Operations is the financial results of NoDak Energy Services, LLC ("NoDak"). NoDak operated and maintained a coal drying system at a customer’s power plant. The NoDak contract expired in the first quarter of 2020.

Income Taxes

Income Tax Disclosure [Abstract]

Income Taxes

Income Taxes

The Company evaluates and updates its estimated annual effective income tax rate on a quarterly basis based on current and forecasted operating results and tax laws. Consequently, based upon the mix and timing of actual earnings compared to projections of earnings between entities that benefit from percentage depletion and those that do not, the effective tax rate may

vary quarterly. The quarterly income tax provision is generally comprised of tax expense on income or a benefit on a loss at the most recent estimated annual effective income tax rate, adjusted for the effect of discrete items.

On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act ("CARES Act") was enacted in response to the COVID-19 pandemic. The CARES Act contains numerous income tax provisions, including among other items, temporary changes regarding the prior and future utilization of net operating losses. The CARES Act allows net operating losses incurred in 2018, 2019, and 2020 to be carried back to each of the five preceding taxable years to generate a refund of previously paid income taxes. The 2020 estimated annual effective tax rate includes the benefit of utilizing the current year forecasted tax basis net operating loss that would otherwise be deductible at the current 21% statutory rate to offset taxable income in years that were taxed at a 35% rate. The Company expects to generate a net operating loss in 2020 primarily due to the realization of certain deferred tax assets. The Company is currently assessing aspects of the CARES Act, including the Company’s ability to utilize the extended carryback provisions.

Nature of Operations and Basis of Presentation (Policies)

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Nature of Operations

The accompanying Unaudited Condensed Consolidated Financial Statements include the accounts of NACCO Industries, Inc.^® (“NACCO”) and its wholly owned subsidiaries (collectively, “NACCO Industries, Inc. and Subsidiaries” or the “Company”). Intercompany accounts and transactions are eliminated in consolidation. NACCO is the public holding company for The North American Coal Corporation^® ("NACoal"). The Company has three operating segments: Coal Mining, North American Mining (“NAMining”) and Minerals Management. The Company also has unallocated items not directly attributable to a reportable segment. See Note 9 to the Unaudited Condensed Consolidated Financial Statements for further discussion of segment reporting.

The Company’s operating segments are further described below:

Coal Mining Segment

During the six months ended June 30, 2020, the operating coal mines are: Bisti Fuels LLC (“Bisti”), Caddo Creek Resources Company, LLC (“Caddo Creek”), Camino Real Fuels, LLC (“Camino Real”), The Coteau Properties Company (“Coteau”), Coyote Creek Mining Company, LLC (“Coyote Creek”), Demery Resources Company, LLC (“Demery”), The Falkirk Mining Company (“Falkirk”), Mississippi Lignite Mining Company (“MLMC”) and The Sabine Mining Company (“Sabine”).

The contract mining agreement between Camino Real and its customer, Dos Republicas Coal Partnership (“DRCP”), terminated effective July 1, 2020 as a result of the unexpected termination by Comisión Federal de Electricidad (“CFE”) of its coal supply contract with an affiliate of DRCP. The termination of the contract between CFE and DRCP eliminated DRCP’s need for coal from Camino Real's Eagle Pass Mine, and will result in mine closure.

Camino Real issued a Notice of Payment Default on June 17, 2020. During the third quarter of 2020, the Company received certain inventory as well as a securitized note in settlement of the outstanding receivable balance as of June 30, 2020 and additional costs incurred through the July 9, 2020 mine closure date. Mine reclamation is the responsibility of DRCP. Camino Real has no legal obligation to perform mine reclamation but is in negotiations with DRCP to potentially perform mine reclamation activities under a new contractual arrangement. Closure of the mine does not materially impact NACCO’s outlook for 2020. The contract mining agreement between Camino Real and DRCP was previously expected to terminate in 2021.

As of June 30, 2020, all of the Liberty Fuels Company, LLC mine areas have been reclaimed and final mine reclamation activities, primarily monitoring, will continue until final bond release.

At all operating coal mines other than MLMC, the Company is paid a management fee per ton of coal or heating unit (MMBtu) delivered. Each contract specifies the indices and mechanics by which fees change over time, generally in line with broad measures of U.S. inflation. The customers are responsible for funding all mine operating costs, including final mine reclamation, and directly or indirectly providing all of the capital required to build and operate the mine. This contract structure eliminates exposure to spot coal market price fluctuations while providing steady income and cash flow with minimal capital investment. Other than at Coyote Creek, debt financing provided by or supported by the customers is without recourse to NACCO and NACoal. See Note 7 for further discussion of Coyote Creek's guarantees.

All operating coal mines other than MLMC meet the definition of a variable interest entity (“VIE”). In each case, NACCO is not the primary beneficiary of the VIE as it does not exercise financial control; therefore, NACCO does not consolidate the results of these operations within its financial statements. Instead, these contracts are accounted for as equity method investments. The income before income taxes associated with these VIE's is reported as Earnings of unconsolidated operations on the Consolidated Statements of Operations and the Company’s investment is reported on the line Investments in unconsolidated subsidiaries in the Consolidated Balance Sheets. The mines that meet the definition of a VIE are referred to collectively as the “Unconsolidated Subsidiaries.” For tax purposes, the Unconsolidated Subsidiaries are included within the NACCO consolidated U.S. tax return; therefore, the income tax expense line on the Consolidated Statements of Operations includes income taxes related to these entities. All of the Unconsolidated Subsidiaries are accounted for under the equity method. See Note 7 for further discussion.

Camino Real previously met the definition of a variable interest entity of which the Company was not the primary beneficiary and therefore NACCO did not consolidate Camino Real’s results of operations within its financial statements.

The Notice of Payment Default and subsequent termination of the contract mining agreement resulted in a reconsideration event, which required reassessment of the Company’s VIE conclusion. As a result of this reconsideration, Camino Real is no longer a VIE and its financial position is consolidated within NACCO’s financial statements as of June 30, 2020. The consolidation of Camino Real did not materially change the Company’s balance sheet. The results of operations for the six months ended June 30, 2020 are reported under the equity method with income before income taxes reported as Earnings of unconsolidated operations on the Consolidated Statements of Operations.  

The MLMC contract is the only operating coal contract in which the Company is responsible for all operating costs, capital requirements and final mine reclamation; therefore, MLMC is consolidated within NACCO’s financial statements. MLMC sells coal to its customer at a contractually agreed-upon price which adjusts monthly, primarily based on changes in the level of established indices which reflect general U.S. inflation rates.

Centennial Natural Resources (“Centennial”), located in Alabama, ceased coal production at the end of 2015. Since 2015, the Company has sold or transferred certain Centennial equipment and mineral reserves. The Company continues to evaluate strategies for the remaining mineral reserves and a dragline, which have no remaining book value. Cash expenditures related to mine reclamation at Centennial will continue until mine reclamation is complete, or ownership of, or responsibility for, the remaining mines is transferred. Centennial is a consolidated entity within the Coal Mining segment as the Company is responsible for carrying costs and final mine reclamation.

NAMining Segment

The NAMining segment provides value-added contract mining and other services for producers of aggregates, lithium and other minerals. The segment is a primary platform for the Company’s growth and diversification outside of the coal industry. NAMining provides contract mining services for independently owned mines and quarries, creating value for its customers by performing the mining aspects of its customers’ operations. This allows customers to focus on their areas of expertise: materials handling and processing, product sales and distribution. NAMining operates primarily at limestone quarries in Florida, but is focused on expanding outside of Florida and into mining materials other than limestone. During 2019, the Company entered into a mining agreement to serve as exclusive contract miner for the Thacker Pass lithium project in northern Nevada. NAMining utilizes both fixed price and cost plus management fee contract structures. Certain of the entities within NAMining segment are VIEs and are accounted for under the equity method as Unconsolidated Subsidiaries. See Note 7 for further discussion.

Minerals Management Segment

The Minerals Management segment promotes the development of the Company’s gas, oil and coal reserves, generating income primarily from royalty-based lease payments from third parties. The Company’s gas, oil and undeveloped coal reserves are located in Ohio (Utica and Marcellus shale natural gas), Louisiana (Haynesville shale and Cotton Valley formation natural gas), Mississippi (coal), Pennsylvania (coal, coalbed methane and Marcellus shale natural gas), Alabama (coal and coalbed methane and natural gas) and North Dakota (coal).

The majority of the Company’s existing reserves were acquired as part of its historical coal mining operations. The Minerals Management segment derives income primarily by entering into contracts with third-party operators, granting them the rights to explore, produce and sell natural resources in exchange for royalty payments based on the lessees' sales of natural gas and, to a lesser extent, oil and coal. Specialized employees in the Minerals Management segment also provide surface and mineral acquisition and lease maintenance services related to Company operations.

Basis of Presentation

Basis of Presentation: These financial statements have been prepared in accordance with U.S. generally accepted accounting principles ("U.S. GAAP") for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation of the financial position of the Company at June 30, 2020, the results of its operations, comprehensive income, cash flows and changes in equity for the six months ended June 30, 2020 and 2019 have been included. These Unaudited Condensed Consolidated Financial Statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2019.

The balance sheet at December 31, 2019 has been derived from the audited financial statements at that date but does not include all of the information or notes required by U.S. GAAP for complete financial statements.

Certain amounts in prior period Unaudited Condensed Consolidated Financial Statements have been reclassified to conform to the current period's presentation.
