Report of Independent Registered Public Accounting Firm

The Board of Directors and Shareholders of NACCO Industries, Inc.

We have audited the accompanying combined balance sheets of The Unconsolidated Mines of The North American Coal Corporation as of December 31, 2010 and 2009, and the related combined statements of net income and comprehensive income, equity, and cash flows for each of the three years in the period ended December 31, 2010. These combined financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. We were not engaged to perform an audit of the Company's internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the combined financial position of The Unconsolidated Mines of The North American Coal Corporation at December 31, 2010 and 2009, and the combined results of their operations and their cash flows for each of the three years in the period ended December 31, 2010 in conformity with U.S. generally accepted accounting principles.

The Unconsolidated Mines of The North American Coal Corporation

Notes to Combined Financial Statements

December 31, 2010, 2009 and 2008

(Amounts in Thousands)

1. Organization

The Coteau Properties Company, The Falkirk Mining Company, The Sabine Mining Company, Demery Resources Company, LLC, Caddo Creek Resources Company, LLC, Camino Real Fuels, LLC, and Liberty Fuels, LLC (collectively, the Unconsolidated Mines) are each wholly owned subsidiaries of The North American Coal Corporation (Parent Company), which is a wholly owned subsidiary of NACCO Industries, Inc. (Ultimate Parent Company).

The Unconsolidated Mines each meet the definition of a variable interest entity. Although the Parent Company owns 100% of the equity and manages the daily operations of these entities, the Parent Company has determined that the equity capital provided 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 Parent Company is not the primary beneficiary of the Unconsolidated Mines and does not consolidate these entities' financial position or results of operations. The Unconsolidated Mines are still considered under common management of the Parent Company and, therefore, are reflected collectively in the Unconsolidated Mines' audited combined financial statements.

The Coteau Properties Company: The Coteau Properties Company (Coteau), an Ohio corporation, was organized on May 23, 1972, pursuant to an agreement between the Parent Company and a wholly owned subsidiary of a diversified energy company (Buyer). Coteau is principally engaged in lignite mining through the operation of a surface mine in North Dakota.

On April 22, 1977, the Buyer exercised its option to enter into a coal sales agreement, as restated June 1, 1979. As of November 1, 1988, all of the Buyer's rights, interests, and obligations under the coal sales agreement were assigned to Dakota Coal Company (Coteau's Customer), a wholly owned subsidiary of Basin Electric Power Cooperative (Basin). This coal sales agreement was subsequently replaced with a coal sales agreement, as amended, between Coteau and Coteau's Customer (Coteau Agreement) and provides Coteau with the option to extend Coteau's agreement up to the year 2037 and provides reimbursement of administrative and general expenses, included in cost of sales in the statements of net income and comprehensive income, from actual costs to reimbursement at a fixed rate per ton.

Under the terms and conditions of the Coteau Agreement, Coteau is to supply coal to an electric generating station and a coal gasification plant, as well as to other third parties. The terms of a related option agreement, as amended, provide that, under certain conditions of default, Coteau's Customer may acquire the assets, subject to the liabilities, for an amount equal to the equity of Coteau.

The Falkirk Mining Company: The Falkirk Mining Company (Falkirk), an Ohio corporation, was organized on August 22, 1974, to enter into a coal sales agreement (Falkirk Agreement) with an electric generation and transmission cooperative (Falkirk's Customer). Falkirk's agreement was restated effective January 1, 2007, to extend the agreement to 2045. Falkirk is principally engaged in lignite mining through the operation of a surface mine in North Dakota.

Under the terms of the Falkirk Agreement, Falkirk's Customer has agreed to provide, or procure from others, the financing required to develop, equip, and operate Falkirk's mine for the life of the Falkirk Agreement. The Falkirk Agreement provides that, under certain conditions of Falkirk's default, Falkirk's Customer may acquire the assets, subject to the liabilities, for an amount equal to the equity of Falkirk.

Falkirk's Customer has entered into an operating agreement with Falkirk whereby a dragline to be used in the production of coal (original cost of approximately $40,000) leased by Falkirk's Customer has been made available to Falkirk without rent.

The Sabine Mining Company: The Sabine Mining Company (Sabine), a Nevada corporation, was organized on November 6, 1980, and entered into a lignite mining agreement, as restated, (Sabine Agreement) with a public utility (Sabine's Customer) in 1981, which was subsequently amended and restated on January 1, 1996, December 1, 2001 and January 1, 2008. Sabine is principally engaged in lignite mining through the operation of a surface mine in Texas.

The Sabine Agreement provides that, under certain conditions of default, Sabine's Customer may acquire the issued and outstanding common stock of Sabine for an amount equal to the equity of Sabine.

Other entities: Demery Resources Company, LLC (Demery), Caddo Creek Resources Company, LLC (Caddo), Camino Real Fuels, LLC (Camino Real), and Liberty Fuels Company, LLC (Liberty) were formed during 2007, 2008 and 2009 to develop, construct, and operate surface mines under long-term contracts for their respective customers. The contracts with the customers allow for reimbursement of all costs plus a management fee. Demery, Caddo, Camino Real and Liberty are in the development

stage. Demery has started mining minimal tons of coal from a test pit. Caddo, Camino Real and Liberty do not currently mine or deliver coal.

Since each of the Unconsolidated Mines has an agreement to provide coal to its respective customers, a significant portion of each of the Unconsolidated Mines' revenue is derived from a single source. The financial position of the Unconsolidated Mines and the Parent Company would be materially affected if the existing contractual relationship with any of the Unconsolidated Mines' customers were terminated or significantly altered.

Management performed an evaluation of the Unconsolidated Mines' activities through March 2, 2011 which is the date these financial statements were issued. No significant subsequent events have occurred that required recognition or disclosure in these financial statements.

2. Significant Accounting Policies

Use of Estimates

The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

Revenue Recognition and Accounts Receivable

Under their respective mining agreements, the Unconsolidated Mines recognize revenue and a related receivable as coal is delivered. The sales price of the coal is based on costs, plus a profit or management fee per ton of coal delivered. As is customary in the coal industry, these agreements provide for monthly settlements. The Unconsolidated Mines' significant credit concentration is uncollateralized; however, historically, no credit losses have been incurred. Management has reviewed the carrying value of its accounts receivable and has determined that a reserve for credit losses is not necessary based on amounts subsequently realized.

Cash and Cash Equivalents

Cash and cash equivalents include cash in banks and highly liquid investments with initial maturities of three months or less. After considering the right of offset, outstanding checks net of their associated funding accounts, are classified as accounts payable.

Inventories

Coal and supply inventories are stated at the lower of cost or market. Cost is determined using the weighted-average method.

Property, Plant and Equipment

Property, plant and equipment are recorded at cost. Depreciation, depletion and amortization are provided in amounts sufficient to amortize the cost of related assets (including assets recorded under capitalized lease obligations) over their estimated useful lives or lease terms and are calculated by either the straight-line method or the units-of-production method based on estimated recoverable tonnage. In the course of preparing a mine for production, the Unconsolidated Mines incur mine development costs prior to initial production, as well as throughout the life of the mine. The Unconsolidated Mines capitalize these costs as a part of plant and equipment in the accompanying combined balance sheets. The Unconsolidated Mines amortize the development costs over their estimated useful life, which is generally the life of the mine or the mine area. Repairs and maintenance costs are expensed when incurred, unless such costs extend the estimated useful life of the asset.

Advance Minimum Royalties

Advance minimum royalties are advance payments made to lessors under terms of mineral lease agreements that are recoupable against future production. These advanced payments are capitalized when paid and charged against income as the coal reserves are mined.

Long-Lived Assets

Upon identification of indicators of impairment, management compares the carrying value of its long-lived assets to the undiscounted cash flows of such assets. When the undiscounted cash flows are less than the related assets' carrying value, the long-lived assets are adjusted to fair value (based on active market quotes, third-party appraisals, or discounted cash flows).

The Unconsolidated Mines of

The North American Coal Corporation

Notes to Combined Financial Statements (continued)

Accounting for Asset Retirement Obligations

Under certain federal and state regulations, the Unconsolidated Mines are required to reclaim land disturbed as a result of mining. Reclamation of disturbed land is a continuous process throughout the terms of the mining agreements. Current reclamation costs are charged to expense in the period incurred and are being recovered as a cost of coal tonnage sold. Costs to complete reclamation after mining has been completed are to be reimbursed under the respective mining agreements.

Authoritative guidance on accounting for asset retirement obligationsprovides accounting requirements for retirement obligations associated with tangible long-lived assets, including: (i) the timing of liability recognition; (ii) initial measurement of the liability; (iii) allocation of asset retirement cost to expense; (iv) subsequent measurement of the liability; and (v) financial statement disclosures. The guidance requires that an asset's retirement cost should be capitalized as part of the cost of the related long-lived asset and subsequently allocated to expense using a systematic and rational method.

The Unconsolidated Mines' asset retirement obligations are for costs to close its surface mines and reclaim the land it has disturbed as a result of its normal mining activities. The Unconsolidated Mines have estimated these costs and recognized a liability and associated asset in accordance with authoritative guidance. The Unconsolidated Mines determined these obligations based on estimates adjusted for inflation, projected to the estimated closure dates, and then discounted using a credit-adjusted, risk-free interest rate. The accretion of the liability is being recognized over the estimated life of the individual asset retirement obligations. The associated asset is recorded in property, plant and equipment in theaccompanying balance sheets.

Since the cost of reclamation is reimbursable under the provisions of the mining agreements, the difference between the capitalized asset retirement obligation and the reclamation liability is recorded as a long-term receivable from the customers. Additionally, the annual costs related to amortization of the asset and accretion of the liability of $5,029, $6,418, and $10,747 in 2010, 2009 and 2008, respectively, are included in cost of sales, and increases the sales to, and the long-term receivable from, the customers. The long-term receivable (see Note 4) will be reimbursed to the Unconsolidated Mines as the costs of reclamation are actually incurred.

There are currently no assets legally restricted for purposes of settling these asset retirement obligations. A reconciliation of the beginning and ending aggregate carrying amount of the asset retirement obligations is as follows:

	December 31
	2010			2009
Beginning balance	$	69,729		$	62,854
Liabilities incurred during the period	13,830			4,599
Liabilities settled during the period	(10,310		)	(2,173		)
Accretion expense	4,648			4,449
Revision in cash flows	(4,481		)	—
	$	73,416		$	69,729

Financial Instruments and Derivative Financial Instruments

Financial instruments held by the Unconsolidated Mines include cash and cash equivalents, accounts receivable, accounts payable and long-term debt. The Unconsolidated Mines do not hold or issue financial instruments or derivative financial instruments for trading purposes.

Recently Issued Accounting Standards

Accounting Standards Adopted in 2010:

On January 1, 2010, the Unconsolidated Mines adopted authoritative guidance issued by the Financial Accounting Standards Board (FASB) for accounting for transfers of financial assets. The guidance requires more information about transfers of financial assets, including securitization transactions, and where entities have continuing exposure to the risks related to transferred financial assets. The guidance eliminates the concept of a “qualifying special-purpose entity” and changes the requirements for derecognizing financial assets. The guidance also requires enhanced disclosures to provide financial statement users with greater transparency about transfers of financial assets and a transferor's continuing involvement with transferred financial assets. The adoption of the guidance did not have a material effect on the Unconsilidated Mines's financial position, results of operations, cash flows or related

Notes to Combined Financial Statements (continued)

disclosures.

On January 1, 2010, the Unconsolidated Mines adopted authoritative guidance issued by the FASB on the consolidation of variable interest entities. The guidance changes how a reporting entity determines when an entity that is insufficiently capitalized or is not controlled through voting (or similar rights) should be consolidated. The guidance requires an ongoing assessment of whether an entity is the primary beneficiary of a variable interest entity and eliminates the quantitative approach previously required for determining the primary beneficiary of a variable interest entity. The guidance also requires additional disclosures regarding a company's involvement with variable interest entities, any significant changes in risk exposure due to that involvement and how the company's involvement with a variable interest entity affects the company's financial statements. The adoption of the guidance did not have a material effect on the Unconsolidated Mines's financial position, results of operations, cash flows or related disclosures.

On December 31, 2010, the Unconsolidated Mines adopted authoritative guidance issued by the FASB on disclosures about the credit quality of financing receivables and the allowance for credit losses. The guidance requires additional disclosures that facilitate financial statement users' evaluation of: (a) the nature of credit risk inherent in the entity's portfolio of financing receivables; (b) how that risk is analyzed and assessed in arriving at the allowance for credit losses; and (c) the changes and reasons for those changes in the allowance for credit losses. In addition, the guidance amends current requirements to include additional disclosures about financing receivables, including: (a) credit quality indicators of financing receivables at the end of the reporting period by class of financing receivables; (b) the aging of past due financing receivables at the end of the reporting period by class of financing receivables; and (c) the nature and extent of troubled debt restructurings that occurred during the period by class of financing receivables and their effect on the allowance for credit losses. The adoption of the guidance did not have a material effect on the Unconsolidated Mine's financial position, results of operations, cash flows or related disclosures.

Accounting Standards Adopted in 2009:

On January 1, 2009, the Unconsolidated Mines adopted authoritative guidance issued by the FASB on business combinations. The guidance modifies the accounting for business combinations by requiring that acquired assets and assumed liabilities be recorded at fair value, contingent consideration arrangements be recorded at fair value on the date of the acquisition and pre-acquisition contingencies will generally be accounted for in purchase accounting at fair value. The guidance also requires that transaction costs be expensed as incurred, acquired research and development be capitalized as an indefinite-lived intangible asset and the requirements for exit and disposal activities be met at the acquisition date in order to accrue for a restructuring plan in purchase accounting. The adoption of the guidance did not have a material effect on the Unconsolidated Mines' financial position, results of operations, cash flows or related disclosures.

On January 1, 2009, the Unconsolidated Mines adopted authoritative guidance issued by the FASB that changes the accounting and reporting for non-controlling interests. The guidance modifies the reporting for non-controlling interests in the balance sheet and minority interest income (loss) in the income statement. The guidance also requires that increases and decreases in the non-controlling ownership interest amount be accounted for as equity transactions. The adoption of the guidance did not have a material effect on the Unconsolidated Mines' financial position, results of operations, cash flows or related disclosures.

On June 30, 2009, the Unconsolidated Mines adopted authoritative guidance issued by the FASB on subsequent events. The guidance provides general standards of accounting for and disclosure of events that occur after the balance sheet date but before financial statements are issued. The guidance provides (a) the period after the balance sheet date during which management of a reporting entity should evaluate events or transactions that may occur for potential recognition or disclosure in the financial statements; (b) the circumstances under which an entity should recognize events or transactions occurring after the balance sheet date in its financial statements; and (c) the disclosures that an entity should make about events or transactions that occurred after the balance sheet date. The adoption of the guidance did not have a material effect on the Unconsolidated Mines' financial position, results of operations, cash flows or related disclosures.

On September 30, 2009, the Unconsolidated Mines adopted authoritative guidance issued by the FASB which establishes the FASB Accounting Standards Codification as the single source of authoritative U.S. generally accepted accounting principles. The Unconsolidated Mines have modified its disclosures to comply with the requirements. The adoption of the guidance did not have a material effect on the Unconsolidated Mines' financial position, results of operations or cash flows.

On December 31, 2009, the Unconsolidated Mines adopted authoritative guidance issued by the FASB on disclosures about postretirement benefit plan assets. The guidance modifies existing requirements to include additional disclosures about plan assets of an employer's defined benefit pension or other postretirement plan. See Note 7 for additional disclosures required by this guidance.

The North American Coal Corporation

Notes to Combined Financial Statements (continued)

Accounting Standards Not Yet Adopted:

In October 2009, the FASB issued authoritative guidance on multiple-deliverable revenue arrangements, which is effective for the Unconsolidated Mines on January 1, 2011 for new revenue arrangements or material modifications to existing agreements. The guidance amends the criteria for separating consideration in multiple-deliverable arrangements. This guidance establishes a selling price hierarchy for determining the selling price of a deliverable, which is based on: (a) vendor-specific objective evidence; (b) third-party evidence; or (c) estimates. This guidance also eliminates the residual method of allocation and requires that arrangement consideration be allocated at the inception of the arrangement to all deliverables using the relative selling price method. In addition, this guidance significantly expands required disclosures related to a vendor's multiple-deliverable revenue arrangements. The Unconsolidated Mines do not expect the adoption of the guidance to have a material effect on its financial position, results of operations, cash flows or related disclosures.

The long-term receivables will be reimbursed to the Unconsolidated Mines as the costs of reclamation, pension and postretirement benefits are actually incurred or paid.

One of the Unconsolidated Mines holds investments in cooperatives that provide electrical service to the mine site. Patronage dividends from cooperatives are recorded as declared. The dividends declared are consistently paid out, but routinely several years after the declaration. These patronage dividends when declared are reflected as a reduction in the cost of coal under the mining agreements. In the event the cooperatives should become unable to pay the patronage dividends previously declared, the Unconsolidated Mines would be required at that time to record an impairment charge against the investment asset, which would be reimbursable under the mining agreement.

6. Advances From Customers and Notes Payable

Advances from Customers

Advances from customers represent amounts advanced to Coteau and Falkirk from their customers or their affiliates to provide working capital and to develop and operate the mines. These advances, which are not guaranteed by either the Parent Company or the Ultimate Parent Company, are secured by substantially all owned assets and assignment of all rights under the agreements. Coteau's advances incur interest at a rate of 6.5%. No repayment schedule has been established for Falkirk's advances, which are noninterest-bearing, due to the funding agreement with the customer.

Estimated maturities for Coteau for the next five years, including current maturities, and Falkirk's customer advances with unspecified repayment schedules are as follows:

2011	$	10,644
2012	10,644
2013	10,644
2014	10,644

Advances with unspecified repayment schedule	83,982
Total advances from customers	191,922
Less current maturities	15,662
Total long-term advances from customers	$	176,260

Notes Payable

Notes payable primarily represents financing which customers arranged and guaranteed for Sabine. Neither the Parent Company nor the Ultimate Parent Company has guaranteed these borrowings. Certain notes payable of Sabine include a fixed charge coverage covenant. Sabine was in compliance with this covenant at December 31, 2010.

Commitment fees paid to banks were approximately $73, $38 and $30 in 2010, 2009 and 2008, respectively, and are included in interest expense in the accompanying combined statements of income and comprehensive income.

To reduce its exposure to changes in the market rate of interest, one of the Unconsolidated Mines previously entered into interest rate swap agreements for the note payable that matured June 30, 2008. This interest rate swap agreement expired in 2008.

7. Pension and Other Postretirement Benefits

Defined Benefit Plans

Substantially all the Unconsolidated Mines' salaried employees hired prior to January 1, 2000, participate in The North American Coal Corporation Salaried Employees Pension Plan (the Plan), a noncontributory defined benefit plan sponsored by the Parent Company. Pension benefits for certain management level employees were frozen effective December 31, 2004. Employees whose benefits were frozen receive retirement benefits under defined contribution retirement plans. Benefits under the defined benefit pension plans are based on years of service and average compensation during certain periods. The Unconsolidated Mines expect to contribute $11,367 in 2011 to this plan. The Unconsolidated Mines participate in a supplemental defined benefit plan that pays monthly benefits to participants directly out of corporate funds. All other pension benefit payments are made from the assets of the Plan. The Unconsolidated Mines expect to make supplemental payments and pay benefits from the assets of the Plan of $4,275 in 2011, $4,935 in 2012, $5,567 in 2013, $6,320 in 2014, $7,106 in 2015, and $50,244 in the five years thereafter.

The actuarial loss and prior service cost included in long-term receivables from customers expected to be recognized in net periodic benefit cost in 2011 are $3,344 ($2,174 net of tax) and $702 ($456 net of tax), respectively.

The projected benefit obligation included in the table above represents the actuarial present value of benefits attributable to employee service rendered to date, including the effects of estimated future pay increases. The accumulated benefit obligation also reflects the actuarial present value of benefits attributable to employee service rendered to date, but does not include the effects of estimated future pay increases.

The expected long-term rate of return on plan assets reflects management's expectations of long-term rates of return on funds invested to provide for benefits included in the projected benefit obligations. The Ultimate Parent Company has established the expected long-term rate of return assumption for plan assets by considering historical rates of return over a period of time that is consistent with the long-term nature of the underlying obligations of these plans. The historical rates of return for each of the asset classes used by the Ultimate Parent Company to determine its estimated rate of return assumption were based upon the rates of return earned by investments in the equivalent benchmark market indices for each of the asset classes.

The Plan maintains an investment policy that, among other things, establishes a portfolio asset allocation methodology with percentage allocation bands for individual asset classes. The investment policy provides that investments are reallocated between asset classes as balances exceed or fall below the appropriate allocation bands.

The following is the actual allocation percentage and target allocation percentage for the plan assets at the measurement date:

	Actual 2010		Actual 2009		Target Allocation Range
U.S. equity securities	52.8	%	52.5	%	41.0%-62.0%
Non-U.S. equity securities	13.1	%	13.0	%	10.0%-16.0%
Fixed income securities	33.6	%	33.7	%	30.0%-40.0%
Money market	0.5	%	0.8	%	0.0%-10.0%

The fair value of each major category of plan assets for the Unconsolidated Mines' pension plans are valued using quoted market prices in active markets for identical assets, or Level 1 in the fair value hierarchy. Following are the values as of December 31:

	2010		2009

Some of the Unconsolidated Mines established Voluntary Employees' Beneficiary Association (VEBA) trusts to provide for future retirement benefits other than pensions. The Unconsolidated Mines made no cash contributions to the VEBA trusts in 2010 and 2009. Contributions made to an IRS-approved VEBA trust are irrevocable and must be used for employee benefits.

The fair value of each major category of plan assets for the Unconsolidated Mines' health care plans held in VEBA trusts are valued using quoted market prices in active markets for identical assets, or Level 1 in the fair value hierarchy. Following are the values as of December 31:

Defined Contribution Plans

For employees hired after December 31, 1999, the Parent Company established a defined contribution plan which requires the Unconsolidated Mines to make retirement contributions based on a formula using age and salary as components of the calculation. For employees hired after December 31, 2005, some of the Unconsolidated Mines contribute a set percentage of the employee's salary. Employees are vested at a rate of 20% for each year of service and become 100% vested after five years of employment. The Unconsolidated Mines recorded contribution expense of approximately $2,173 in 2010, $1,947 in 2009, and $1,419 in 2008 related to this plan.

Substantially all the Unconsolidated Mines' salaried employees also participate in a defined contribution plan sponsored by the Parent Company. Employee contributions are matched by the Unconsolidated Mines up to a limit of 5% of the employee's salary. The Unconsolidated Mines' contributions to this plan were approximately $3,946 in 2010, $3,868 in 2009, and $3,698 in 2008.

Under the provisions of each of the Unconsolidated Mines' agreements, retirement related costs will be recovered as a cost of coal tonnage sold.

8. Leasing and Other Commitments

The Unconsolidated Mines lease certain mining equipment under cancelable and noncancelable capital and operating leases that expire at various dates through 2025. Many leases are renewable for additional periods at terms based upon the fair market value of the leased items at the renewal dates.

Future minimum lease payments as of December 31, 2010, for all capital lease obligations are as follows:

2011	$	51,715
2012	48,983
2013	48,577
2014	43,965
2015	40,329
Thereafter	135,871
Total minimum lease payments	369,440
Amounts representing interest	(83,845		)
Present value of net minimum lease payments	285,595
Current maturities	(34,754		)
Long-term capital lease obligations	$	250,841

As of December 31, 2010, $73,761 of the long-term capital lease obligations and $12,100 of the current maturities in the table above are due to a customer of one of the Unconsolidated Mines.

Amortization of assets recorded under capital lease obligations is included in depreciation, depletion and amortization in the financial statements. Assets recorded under capital leases are included in property, plant and equipment and consist of the following:

	December 31
	2010			2009
Plant and equipment	$	390,510		$	368,357
Accumulated amortization	(124,780		)	(106,676		)
	$	265,730		$	261,681

Under the provisions of the mining agreements, the customers are required to pay, as a part of the cost of coal delivered, an amount equal to the annual lease payments. Interest and amortization expense in excess of annual lease payments are deferred and recognized in years when annual lease payments exceed interest expense and amortization. These excess costs are recorded as receivables from the customers and are included in deferred lease costs in the accompanying combined balance sheets.

Rental expense for all operating leases was $4,917 in 2010, $5,681 in 2009, and $5,372 in 2008.

9. Income Taxes

The Unconsolidated Mines are included in the consolidated federal income tax return filed by the Ultimate Parent Company. The Unconsolidated Mines have entered into a tax-sharing agreement with the Ultimate Parent Company under which federal income taxes are computed by the Unconsolidated Mines on a separate return basis. The current portion of such tax is paid to the Ultimate Parent Company, except that net operating loss and tax credit carryovers that benefit the consolidated tax return are advanced to the Unconsolidated Mines and are repaid as utilized on a separate-return basis. To the extent that these carryovers are not used on a separate return basis, the Unconsolidated Mines are required, under conditions pursuant to the tax-sharing agreement, to refund to the Ultimate Parent Company the balance of carryovers advanced and not used by the Unconsolidated Mines prior to the expiration of such carryovers.

The provision for income taxes consists of the following:

	Years Ended December 31
	2010		2009		2008
Current:
Federal	$	7,933	$	6,448	$	6,923
Total current tax provision	7,933		6,448		6,923

A summary of the primary components of the deferred tax assets and liabilities included in the accompanying combined balance sheets resulting from differences in the book and tax basis of assets and liabilities are as follows:

	December 31
	2010			2009
Deferred tax assets:
Accrued expense and reserves	$	6,559		$	4,981
Pension benefits	(1,621		)	397
Asset valuation	4,943			4,754
Inventory	2,190			1,776
Tax attribute carryforward	170			—
Other employee benefits	1,370			1,408
Total deferred tax assets	13,611			13,316
Deferred tax liabilities:
Property, plant and equipment	(30,923		)	(28,319		)
Total deferred tax liabilities	(30,923		)	(28,319		)
Net deferred tax liability	$	(17,312	)	$	(15,003	)

The Unconsolidated Mines regularly review the need for a valuation allowance against deferred tax assets and recognizes these deferred tax assets to the extent that realization is more likely than not. Based on a review of earnings history and trends, forecasted earnings, and the relevant expiration of carryforwards, the Unconsolidated Mines believe that no valuation allowance was necessary at December 31, 2010 or 2009.

10. Fair Value of Financial Instruments

The carrying amounts for cash and cash equivalents, accounts receivable, and accounts payable approximate fair value due to the short term maturities of these instruments. The fair value of notes payable and one of the Unconsolidated Mines advances from customer were determined based on the discounted value of the future cash flows and one of the Unconsolidated Mines advances from customer, which has no specified repayment schedule was determined based on the discounted value of the total payment at the end of the contract term, using borrowing rates currently available to the Unconsolidated Mines for bank loans with similar terms and maturities, taking into account company credit risk.

The fair value compared to the carrying value is summarized as follows:

	December 31
	2010			2009
Fair value:
Notes payable	$	(53,451	)	$	(58,693	)
Advances from customers	$	(140,418	)	$	(134,291	)
Carrying value:

14. Contingencies

Various legal and regulatory proceedings and claims have been or may be asserted against the Unconsolidated Mines relating to the conduct of their businesses, including environmental and other claims. These proceedings are incidental to the ordinary course of business of the Unconsolidated Mines. Management believes that it has meritorious defenses and will vigorously defend itself 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. Although the ultimate disposition of these proceedings is not presently determinable, management believes, after consultation with its legal counsel, that the likelihood is remote that material costs will be incurred in excess of accruals already recognized and would not have a significant impact on the Unconsolidated Mines' financial position or results of operations.
