Arch Coal, Inc. and Subsidiaries
Notes to Condensed Consolidated Financial Statements
(unaudited)

1. Basis of Presentation

     The accompanying unaudited condensed consolidated financial statements include the accounts of Arch Coal, Inc. and its subsidiaries and controlled entities (the “Company”). The Company’s primary business is the production of steam and metallurgical coal from surface and underground mines located throughout the United States, for sale to utility, industrial and export markets. The Company’s mines are located in southern West Virginia, eastern Kentucky, Virginia, Wyoming, Colorado and Utah. All subsidiaries (except as noted below) are wholly-owned. Intercompany transactions and accounts have been eliminated in consolidation.

     The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States for interim financial reporting and U.S. Securities and Exchange Commission regulations. In the opinion of management, all adjustments, consisting of normal, recurring accruals considered necessary for a fair presentation, have been included. Results of operations for the three month period ended March 31, 2008 are not necessarily indicative of results to be expected for the year ending December 31, 2008. These financial statements should be read in conjunction with the audited financial statements and related notes as of and for the year ended December 31, 2007 included in Arch Coal, Inc.’s Annual Report on Form 10-K filed with the U.S. Securities and Exchange Commission.

     The Company owns a 99% membership interest in a joint venture named Arch Western Resources, LLC (“Arch Western”) which operates coal mines in Wyoming, Colorado and Utah. The Company also acts as the managing member of Arch Western.

2. Accounting Policies

     Accounting Pronouncements Adopted

     On January 1, 2008, the Company adopted Statement of Financial Accounting Standards No. 157, Fair Value Measurements (“Statement No. 157”). Statement No. 157 defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements under other accounting pronouncements that require or permit fair value measurements. Statement No. 157 was adopted prospectively for the Company’s financial instruments. The FASB deferred the effective date of Statement No. 157 for one year for nonfinancial assets and liabilities that are recognized or disclosed at fair value in the financial statements on a nonrecurring basis, which the Company will adopt effective January 1, 2009.

     On January 1, 2008, Statement of Financial Accounting Standards No. 159, The Fair Value Option for Financial Assets and Financial Liabilities — Including an Amendment of FASB Statement No. 115 (“Statement No. 159”) became effective. Statement No. 159 permits entities the choice to measure certain financial instruments and other items at fair value. The Company did not elect to measure any additional financial instruments or other items at fair value.

     On January 1, 2008, the Company adopted Staff Position FIN 39-1, Amendment of FASB Interpretation 39 (“FSP FIN 39-1”). FSP FIN 39-1 permits a reporting entity to offset fair value amounts recognized for the right to reclaim or the obligation to return cash collateral against fair value amounts recognized for derivative instruments executed with the same counterparty under the same master netting arrangement that have been offset. The Company did not elect to net amounts related to cash collateral with the fair value of derivatives with the same counterparty. The Company’s current liability for the obligation to return cash collateral was $2.8 million and $3.0 million at March 31, 2008 and December 31, 2007, respectively.

      Accounting Standards Issued and Not Yet Adopted

     In December 2007, the FASB issued Statement of Financial Accounting Standards No. 160, Noncontrolling Interests in Consolidated Financial Statements, an amendment of ARB No. 51 (“Statement No. 160”). Statement No. 160 requires that a noncontrolling interest (minority interest) in a consolidated subsidiary be displayed in the consolidated balance sheet as a separate component of equity. The amount of net income attributable to the noncontrolling interest will be included in consolidated net income on the face of the consolidated statement of income. Statement No. 160 also includes expanded disclosure requirements regarding the interests of the parent and its noncontrolling interest. Statement No. 160 is effective for fiscal years beginning on or after December 15, 2008.

Early adoption is not allowed. The Company does not expect adoption of Statement No. 160 will have a material impact on the Company’s financial position or results of operations.

     In March 2008, the FASB issued Statement of Financial Accounting Standards No. 161, Disclosures about Derivative Instruments and Hedging Activities, an amendment of FASB Statement No. 133 (“Statement No. 161”). Statement No. 161 requires additional disclosures about derivatives and hedging activities, including qualitative disclosures about objectives for using derivatives. It also requires tabular disclosures about gross fair value amounts of derivative instruments, gains and losses on derivative instruments by type of contract, and the locations of these amounts in the financial statements. Statement No. 161 is effective for financial statements issued for fiscal years and interim periods beginning after November 15, 2008, with early application encouraged. The Company is currently assessing Statement No. 161 to determine the impact of the new disclosure requirements.

3. Fair Value Measurements

     Statement No. 157 establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy, as defined below, gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs.

	•		Level 1, defined as observable inputs such as quoted prices in active markets for identical assets.
	•		Level 2, defined as observable inputs other than Level 1 prices. These include quoted prices for similar assets or liabilities in an active market, quoted prices for identical assets and liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. The Company’s level 2 assets and liabilities include commodity contracts with quoted prices in over-the-counter markets or direct broker quotes.
	•		Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions. These include the Company’s commodity contracts valued using modeling techniques, such as Black-Scholes, that require the use of inputs that are not observable.

     The table below sets forth, by level, the Company’s financial assets and liabilities that are accounted for at fair value:

		Fair value at March 31, 2008
		Total				Level 1				Level 2				Level 3
		(In thousands)
Assets:
Available-for-sale investments		$	1,651			$	1,651			$	—			$	—
Derivatives			57,705				5,863				38,749				13,093
Total assets		$	59,356			$	7,514			$	38,749			$	13,093
Liabilities:
Derivatives		$	8,053			$	—			$	8,053			$	—

     The following table summarizes the change in the fair values of financial instruments categorized as level 3.

		Three Months Ended
		March 31, 2008
		(In thousands)
Beginning balance		$	3,256
Realized and unrealized gains recognized in earnings			5,443
Realized and unrealized gains recognized in other comprehensive income			4,210
Settlements, purchases and issuances			184
Ending balance		$	13,093

     Unrealized gains during the three months ended March 31, 2008 related to level 3 financial instruments held on March 31, 2008 were $7.8 million.

4. Stock-Based Compensation

     During the three months ended March 31, 2008, the Company granted options to purchase 0.8 million shares of common stock with a weighted average exercise price of $52.69 and a weighted average grant-date fair value of $21.26 per share. The options’ fair value was determined using the Black-Scholes option pricing model, using a weighted average risk-free rate of 2.9%, a weighted average dividend yield of 0.5% and a weighted average volatility of 45.5%. The options vest ratably over three years. The options provide for the continuation of vesting for retirement-eligible recipients that meet certain criteria. The expense for these options will be recognized through the date that the employee first becomes eligible to retire and is no longer required to provide service to earn part or all of the award. The Company also granted 0.1 million shares of restricted stock and restricted stock units during the three months ended March 31, 2008 at a weighted average grant-date fair value of $52.69 per share. The restricted stock and restricted stock units vest over a period ranging from approximately two to four years.

     During the three months ended March 31, 2008, stock price and EBITDA performance measurements were satisfied under the Company’s performance-contingent phantom stock awards, and the Company issued 0.2 million shares of common stock and paid cash of $3.5 million under the awards.

     The Company recognized stock-based compensation expense from all plans of $4.7 million and $1.6 million for the three months ended March 31, 2008 and 2007, respectively. This expense is primarily included in selling, general and administrative expenses in the accompanying condensed consolidated statements of income.

5. Inventories

     Inventories consist of the following:

		March 31,				December 31,
		2008				2007
		(In thousands)
Coal		$	75,320			$	61,656
Repair parts and supplies, net of allowance			120,846				116,129
		$	196,166			$	177,785

6. Income taxes

     During the three months ended March 31, 2008, the Company reduced the valuation allowance related to state net operating loss carryforwards by $4.7 million, resulting from a change in management’s assessment of the Company’s ability to utilize these net operating loss carryforwards. A tax law change in West Virginia is expected to enable the Company to utilize existing net operating loss carryforwards.

     The Company’s treatment of the acquisition of the coal operations of Atlantic Richfield Company (“ARCO”) and the simultaneous combination of the acquired ARCO operations and the Company’s Wyoming operations into the Arch Western joint venture is currently under review by the IRS. The Company has recognized a deferred tax asset related to its investment in Arch Western under FIN 48, but the outcome of the review could result in adjustments to the basis of the partnership assets. The outcome of the negotiations is uncertain, however, it is possible the Company could be required to decrease its deferred income tax assets in an amount up to $25.0 million.

Effect of common stock equivalents arising from Preferred Stock			138				508
Diluted weighted average shares outstanding			144,596				143,786

12. Guarantees

     The Company has agreed to continue to provide surety bonds and letters of credit for reclamation and retiree healthcare obligations of Magnum Coal Company (“Magnum”) related to the properties the Company sold to Magnum on December 31, 2005. The Purchase Agreement requires Magnum to reimburse the Company for costs related to the surety bonds and letters of credit and to use commercially reasonable efforts to replace the obligations. If the surety bonds and letters of credit related to the reclamation obligations are not replaced by Magnum within a specified period of time, Magnum must post a letter of credit in favor of the Company in the amounts of the reclamation obligations. At March 31, 2008, the Company had $92.0 million of surety bonds related to properties sold to Magnum.

     Magnum also acquired certain coal supply contracts with customers who have not consented to the assignment of the contract from the Company to Magnum. The Company has committed to purchase coal from Magnum to sell to those customers at the same price it is charging the customers for the sale. In addition, certain contracts have been assigned to Magnum, but the Company has guaranteed Magnum’s performance under the contracts. The longest of the coal supply contracts extends to the year 2017. If Magnum is unable to supply the coal for these coal sales contracts then the Company would be required to purchase coal on the open market or supply contracts from its existing operations. At market prices effective at March 31, 2008, the cost of purchasing 15.4 million tons of coal to supply the contracts that have not been assigned over their duration would exceed the sales price under the contracts by approximately $507.4 million, and the cost of purchasing 5.0 million tons of coal to supply the assigned and guaranteed contracts over their duration would exceed the sales price under the contracts by approximately $214.1 million. The Company has also guaranteed Magnum’s performance under certain operating leases, the longest of which extends through 2011. If the Company were required to perform under its guarantees of the operating lease agreements, it would be required to make $8.7 million of lease payments. As the Company does not believe that it is probable that it would have to purchase replacement coal or fulfill its obligations under the lease guarantees, no liabilities have been recorded in the financial statements as of March 31, 2008. However, if the Company would have to perform under these guarantees, it could potentially have a material adverse effect on the business, results of operations and financial condition of the Company.

     In connection with the Company’s acquisition of the coal operations of ARCO and the simultaneous combination of the acquired ARCO operations and the Company’s Wyoming operations into the Arch Western joint venture, the Company agreed to indemnify the other member of Arch Western against certain tax liabilities in the event that such liabilities arise prior to June 1, 2013 as a result of certain actions taken, including the sale or other disposition of certain properties of Arch Western, the repurchase of certain equity interests in Arch Western by Arch Western or the reduction under certain circumstances of indebtedness incurred by Arch Western in connection with the acquisition. If the Company were to become liable, the maximum amount of potential future tax payments was $58.7 million at March 31, 2008, which is not recorded as a liability on the Company’s financial statements. Since the indemnification is dependent upon the initiation of activities within the Company’s control and the Company does not intend to initiate such activities, it is remote that the Company will become liable for any obligation related to this indemnification. However, if such indemnification obligation were to arise, it could potentially have a material adverse effect on the business, results of operations and financial condition of the Company.

13. Contingencies

     The Company is a party to numerous claims and lawsuits with respect to various matters. The Company provides for costs related to contingencies when a loss is probable and the amount is reasonably determinable. After

conferring with counsel, it is the opinion of management that the ultimate resolution of pending claims will not have a material adverse effect on the consolidated financial condition, results of operations or liquidity of the Company.

14. Segment Information

     The Company has three reportable business segments, which are based on the major low-sulfur coal basins in which the Company operates. Each of these reportable business segments includes a number of mine complexes. The Company manages its coal sales by coal basin, not by individual mine complex. Geology, coal transportation routes to customers, regulatory environments and coal quality are generally consistent within a basin. Accordingly, market and contract pricing have developed by coal basin. Mine operations are evaluated based on their per-ton operating costs (defined as including all mining costs but excluding pass-through transportation expenses), as well as on other non-financial measures, such as safety and environmental performance. The Company’s reportable segments are the Powder River Basin (PRB) segment, with operations in Wyoming; the Western Bituminous (WBIT) segment, with operations in Utah, Colorado and southern Wyoming; and the Central Appalachia (CAPP) segment, with operations in southern West Virginia, eastern Kentucky and Virginia.

     Operating segment results for the three months ended March 31, 2008 and 2007 are presented below. Results for the operating segments include all direct costs of mining. Corporate, Other and Eliminations includes unrealized gains on derivatives, corporate overhead, land management, other support functions, and the elimination of intercompany transactions.

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

     This document contains “forward-looking statements” — that is, statements related to future, not past, events. In this context, forward-looking statements often address our expected future business and financial performance, and often contain words such as “expects,” “anticipates,” “intends,” “plans,” “believes,” “seeks,” or “will.” Forward-looking statements by their nature address matters that are, to different degrees, uncertain. For us, particular uncertainties arise from changes in the demand for our coal by the domestic electric generation industry; from legislation and regulations relating to the Clean Air Act and other environmental initiatives; from operational, geological, permit, labor and weather-related factors; from fluctuations in the amount of cash we generate from operations; from future integration of acquired businesses; and from numerous other matters of national, regional and global scale, including those of a political, economic, business, competitive or regulatory nature. These uncertainties may cause our actual future results to be materially different than those expressed in our forward-looking statements. We do not undertake to update our forward-looking statements, whether as a result of new information, future events or otherwise, except as may be required by law. For a description of some of the risks and uncertainties that may affect our future results, see “Risk Factors” under Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2007 and in Part II, Item 1A of this Quarterly Report on Form 10-Q.

Overview

     We are one of the largest coal producers in the United States. Since federal and state environmental regulations limit the amount of sulfur dioxide that power plants may emit, we believe demand for low sulfur coal exceeds demand for other types of coal. As a result, we focus on mining, processing and marketing coal with low sulfur content for sale to domestic power plants, steel mills and industrial facilities.

     The locations of our mines enable us to ship coal to most of the major coal-fueled power plants in the United States, as well as key export terminals. Our three reportable business segments are based on the low-sulfur coal producing regions in the United States in which we operate — the Powder River Basin, the Western Bituminous region and the Central Appalachia region. These geographically distinct areas are characterized by geology, coal transportation routes to consumers, regulatory environments and coal quality. These regional similarities have caused market and contract pricing environments to develop by coal region and form the basis for the segmentation of our operations.

     The Powder River Basin is located in northeastern Wyoming and southeastern Montana. The coal we mine from surface operations in this region has a very low sulfur content and a low heat value compared to the other regions in which we operate. The price of Powder River Basin coal is generally less than that of coal produced in other regions because Powder River Basin coal exists in greater abundance, is easier to mine and thus has a lower cost of production. Because Powder River Basin coal is generally lower in heat value, some power plants must blend it with higher Btu coal or retrofit existing coal plants to accommodate Powder River Basin coal. The Western Bituminous region includes western Colorado, eastern Utah and southwestern Wyoming. Coal we mine from underground mines in this region typically has a low sulfur content and varies in heat value. Central Appalachia includes eastern Kentucky, Virginia and southern West Virginia. Coal we mine from both surface and underground mines in this region generally has a high heat value and low sulfur content. In addition, a portion of the coal we produce in the Central Appalachia region consists of metallurgical coal. We are typically able to sell metallurgical coal to customers in the steel industry at prices that exceed the price we are able to sell steam coal to power plants and industrial facilities because metallurgical coal has high heat content, low expansion pressure, low sulfur content and various other chemical attributes.

     In the first quarter of 2008, we continued the efforts we had begun in prior periods aimed at positioning our operations for increasing global and domestic coal demand. We believe that growing domestic and international coal demand, along with persistent challenges in augmenting global coal production, infrastructure and transportation networks, has led to a shift in worldwide coal trade. Constrained global coal supply has allowed the United States to become a more significant exporter of metallurgical and steam coal. We believe that a strengthening international coal market is positively influencing domestic coal markets, and we expect that trend to continue. In fact, we anticipate that continued increases in global and domestic coal-based electricity generation, increases in net coal exports from the United States and production difficulties, particularly in the Central Appalachian region, will have a positive influence on future coal prices. As a result, we have not yet priced a portion of the coal we plan to produce over the next several years in order to take advantage of expected price increases. At March 31, 2008, our expected unpriced production approximated between 8 million to 13 million tons

for the remainder of 2008, between 75 million to 85 million tons in 2009 and between 95 million to 105 million tons in 2010.

     The opening of the Mountain Laurel complex has enabled us to take advantage of increasing global metallurgical coal demand. Metallurgical coal shipments represented nearly 30% of our production sold out of the Central Appalachia region during the first quarter of 2008.

Results of Operations

     Three Months Ended March 31, 2008 Compared to Three Months Ended March 31, 2007

     Summary. Our results during the three months ended March 31, 2008 when compared to the three months ended March 31, 2007 were affected primarily by stronger market conditions, offset in part by an upward pressure on commodity costs and higher depreciation, depletion and amortization costs.

     Revenues. The following table summarizes information about coal sales during the three months ended March 31, 2008 and compares those results to the comparable information for the three months ended March 31, 2007:

		Three Months Ended March 31								Increase
		2008				2007				$				%
		(Amounts in thousands, except per ton data)
Coal sales		$	699,350			$	571,349			$	128,001				22.4	%
Tons sold			34,828				31,931				2,897				9.1	%
Coal sales realization per ton sold		$	20.08			$	17.89			$	2.19				12.2	%

     Coal sales. Coal sales increased from the first quarter of 2007 to the first quarter of 2008 due to higher price realizations across all segments, an increase in sales volumes, primarily in the Powder River Basin, and a greater percentage of metallurgical coal sales in Central Appalachia. We have provided more information about the tons sold and the coal sales realizations per ton by operating segment under the heading “Operating segment results” beginning on page 12.

     Expenses, costs and other. The following table summarizes expenses, costs, changes in fair value of derivatives and other operating income, net for the three months ended March 31, 2008 and compares those results to the comparable information for the three months ended March 31, 2007:

										Increase (Decrease)
		Three Months Ended March 31								in Net Income
		2008				2007				$				%
		(Amounts in thousands)
Cost of coal sales		$	514,404			$	449,330			$	(65,074	)			(14.5	)%
Depreciation, depletion and amortization			73,042				57,620				(15,422	)			(26.8	)
Selling, general and administrative expenses			25,680				18,987				(6,693	)			(35.3	)
Change in fair value of coal derivatives			(30,558	)			(1,063	)			29,495				2,774.7
Other operating (income) expense, net			332				(4,388	)			(4,720	)			(107.6	)
		$	582,900			$	520,486			$	(62,414	)			(12.0	)%

     Cost of coal sales. Our cost of coal sales increased from the first quarter of 2007 to the first quarter of 2008 primarily due to the increase in sales volumes, an increase in transportation costs, sales-sensitive costs and higher per-ton production costs in the Powder River Basin. We have provided more information about our operating segments under the heading “Operating segment results” beginning on page 12.

     Depreciation, depletion and amortization. The increase in depreciation, depletion and amortization expense from the first quarter of 2007 to the first quarter of 2008 is due primarily to the costs of capital improvement and mine development projects that we capitalized in 2007, notably the Mountain Laurel longwall mine. We have provided additional information concerning our capital spending in the section entitled “Liquidity and Capital Resources” beginning on page 13.

     Selling, general and administrative expenses. The increase in selling, general and administrative expenses from the first quarter of 2007 to the first quarter of 2008 is due primarily to an increase in the expense associated with stock-based compensation, as well as other employee compensation costs that are based on the achievement of certain performance metrics. These increases were partially offset by a decrease in the expense associated with our deferred compensation plans, which results from changes in the value of our common stock.

     Change in fair value of coal derivatives. The change in fair value of coal derivatives relates to coal derivatives

recorded on the balance sheet that have not been designated as hedge instruments in a hedging relationship. The increase in the change in fair value of derivatives is primarily the result of the increase in market pricing during the first quarter of 2008.

     Other operating (income) expense, net. The decrease in net income from changes in other operating (income) expense, net in the first quarter of 2008 compared to the first quarter of 2007 is due primarily to $1.8 million of unrealized losses on investments in marketable equity securities reclassified in 2008 from other comprehensive income and a decrease in the value of our deferred compensation plan assets during 2008 of $1.9 million.

     Operating segment results. The following table shows results by operating segment for the three months ended March 31, 2008 and compares those amounts to the comparable information for the three months ended March 31, 2007:

		Three Months Ended March 31								Increase (Decrease)
		2008				2007				$				%
		(Tons in thousands)

Operating margin per ton sold (2)		$	12.16			$	2.96			$	9.20				310.8	%

     Powder River Basin — Sales volume in the Powder River Basin was higher in the first quarter of 2008 when compared to the first quarter of 2007 due primarily to an unplanned belt outage and weather-related shipment challenges that occurred in the first quarter of 2007. Increases in sales prices during the first quarter of 2008 when compared with the first quarter of 2007 reflect higher pricing on contract and market index-priced tons. On a per-ton basis, operating margins in the first quarter of 2008 decreased from the first quarter of 2007 due to an increase in per-ton costs, which offset the contribution of higher sales prices. The increase in per-ton costs resulted primarily from higher sales-sensitive costs, higher diesel fuel prices and costs related to planned truck and shovel maintenance.

     Western Bituminous — In the Western Bituminous region, sales volume increased during the first quarter of 2008 when compared with the first quarter of 2007, driven largely by increased demand in the region. Higher sales prices during the first quarter of 2008 represent higher contract pricing resulting from the roll-off of lower-priced legacy contracts. The increase in sales prices was offset to some degree by a less favorable mix of customer shipments during the first quarter of 2008. Higher sales prices resulted in higher operating margins per ton for the first quarter of 2008 compared to the first quarter of 2007, partially offset by the impact of higher depreciation, depletion and amortization costs.

     Central Appalachia — Our sales volumes in Central Appalachia increased during the first quarter of 2008 when compared with the first quarter of 2007 primarily due to the commencement of production at our Mountain Laurel complex at the beginning of the fourth quarter of 2007. Sales from our Mountain Laurel complex during the first quarter of 2008 exceeded the sales volume from our former Mingo Logan-Ben Creek facility, which we sold at the end of the second quarter of 2007. Higher realized prices in the first quarter of 2008 reflect the increase in metallurgical coal volume as well as higher overall pricing on metallurgical and steam coal sales. Our metallurgical

coal volumes sold in the first quarter of 2008 of 0.8 million tons were more than 50% higher than the approximately 0.5 million tons we sold in the first quarter of 2007. Operating margins per ton for the first quarter of 2008 increased from the first quarter of 2007 due to the increase in sales prices, net of the impact of higher sales-sensitive costs, and a decrease in cash costs per-ton. Mountain Laurel is a lower-cost operation than our average for the region, which resulted in the decrease in cash costs per ton in the first quarter of 2008. These margin improvements were partially offset by the effect of higher depreciation, depletion and amortization costs, primarily from the Mountain Laurel start-up.

     Net interest expense. The following table summarizes our net interest expense for the three months ended March 31, 2008 and compares that information to the comparable information for the three months ended March 31, 2007:

		Three Months Ended March 31								Decrease in Net Income
		2008				2007				$				%
		(Amounts in thousands)
Interest expense		$	(20,488	)		$	(17,258	)		$	(3,230	)			(18.7	)%
Interest income			425				671				(246	)			(36.7	)
		$	(20,063	)		$	(16,587	)		$	(3,476	)			(21.0	)%

     The increase in interest expense during the first quarter of 2008 compared to the year-ago period resulted primarily from a decrease in interest capitalized during the period. We capitalized $2.1 million of interest during the three months ended March 31, 2008 and $5.2 million during the three months ended March 31, 2007. For more information on our ongoing capital improvement and development projects, see “Liquidity and Capital Resources” below.

     Other non-operating expense. Amounts reported as non-operating consist of income or expense resulting from our financing activities other than interest. We previously had amounts deferred from the termination of hedge accounting related to interest rate swaps, and other non-operating expense for the three months ended March 31, 2007 represents the amortization of the amounts that had previously been deferred.

     Income taxes. The following table summarizes our income tax expense for the three months ended March 31, 2008 and compares that information to the comparable information for the three months ended March 31, 2007:

		Three Months Ended March 31								Increase
		2008				2007				$				%
		(Amounts in thousands)
Provision for income taxes		$	15,240			$	4,650			$	10,590				227.7	%

     Our effective tax rate is sensitive to changes in estimates of annual profitability and percentage depletion. An increase in the effective rate from the first quarter of 2007 to the first quarter of 2008 is primarily the result of the impact of percentage depletion. We also reduced our valuation allowance related to state net operating loss carryforwards by $4.7 million in the first quarter of 2008 due to a tax law change in West Virginia that is expected to enable us to utilize existing net operating loss carryforwards.

Liquidity and Capital Resources

     Our primary sources of cash include sales of our coal production to customers, borrowings under our credit facilities or other financing arrangements, sales of assets, and debt and equity offerings related to significant transactions. Excluding any significant mineral reserve acquisitions, we generally satisfy our working capital requirements and fund capital expenditures and debt-service obligations with cash generated from operations or borrowings under our credit facilities, accounts receivable securitization or commercial paper programs. We believe that cash generated from operations, borrowings under our credit facilities or other financing arrangements and sales of assets will be sufficient to meet working capital requirements, anticipated capital expenditures and scheduled debt payments for at least the next several years. Our ability to satisfy debt service obligations, to fund planned capital expenditures, to make acquisitions, to repurchase our common shares and to pay dividends will depend upon our future operating performance, which will be affected by prevailing economic conditions in the coal industry and financial, business and other factors, some of which are beyond our control.

     The following is a summary of cash provided by or used in each of the indicated types of activities during the respective periods:

		Three Months Ended March 31
		2008				2007
		(in thousands)
Cash provided by (used in):
Operating activities		$	133,729			$	83,185
Investing activities			(263,960	)			(263,806	)
Financing activities			138,385				186,860

     Cash provided by operating activities increased $50.5 million in the first three months of 2008 compared to the first three months of 2007 primarily as a result of an increase in net income, which was partially offset by an increased investment in working capital.

     Cash used in investing activities for the first three months of 2008 was $264.0 million, which was comparable to cash used in investing activities for the first three months of 2007. Capital expenditures decreased $10.3 million during the first quarter of 2008 compared to the first quarter of 2007. During the first three months of 2007 and 2008, we made the third and fourth of five annual payments of $122.2 million on the Little Thunder federal coal lease. Additionally, in the first three months of 2008, we spent approximately $25.0 million on the construction of a new loadout facility at our Black Thunder mine in Wyoming and approximately $95.0 million on maintenance capital, which includes $55.0 million for the transition to a new reserve area at our West Elk mining complex in Colorado. In the first quarter of 2007, we acquired property and reserves of approximately $52.0 million, spent approximately $30.0 million on the development of the Mountain Laurel complex in Central Appalachia, and made payments of approximately $17.0 million for a new longwall at our Sufco mine in Utah. Also during the first three months of 2007, we recovered $13.5 million from the lease of equipment in the Powder River Basin. We had previously made deposits to purchase the equipment.

     Cash provided by financing activities decreased $48.5 million during the first three months of 2008 compared to the first three months of 2007. The decrease results primarily from a decrease in borrowings under our credit facilities during the first three months of 2008 when compared with the first three months of 2007. We had available borrowing capacity of approximately $489.0 million under our lines of credit at March 31, 2008. In April 2008, we increased our commercial paper program to $100.0 million. In addition, dividends paid increased $1.4 million due to an increase in the dividend rate in April 2007.

Ratio of Earnings to Fixed Charges

     The following table sets forth our ratios of earnings to combined fixed charges and preference dividends for the periods indicated:

		Three Months Ended March 31
		2008				2007
Ratio of earnings to combined fixed charges and preference dividends			5.14x				2.24x

     Newly Adopted Accounting Pronouncements

     On January 1, 2008, we adopted Financial Accounting Standards Board Statement No. 157, Fair Value Measurements, which we refer to as Statement No. 157. Statement No. 157 defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements under other accounting pronouncements that require or permit fair value measurements. Statement No. 157 was adopted prospectively for our financial instruments. The effective date of Statement No. 157 was deferred for one year for nonfinancial assets and liabilities that are recognized or disclosed at fair value in the financial statements on a nonrecurring basis, which we will adopt effective January 1, 2009.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

     We manage our commodity price risk for our non-trading, long-term coal contract portfolio primarily through

the use of long-term coal supply agreements. At March 31, 2008, our expected unpriced production approximated between 8 million to 13 million tons for the remainder of 2008, between 75 million to 85 million tons in 2009 and between 95 million to 105 million tons in 2010.

     In addition to the other quantitative and qualitative disclosures about market risk contained in this report, you should see Item 7A of our Annual Report on Form 10-K for the year ended December 31, 2007. There have been no other material changes in our exposure to market risk since December 31, 2007.

Item 4. Controls and Procedures.

     We performed an evaluation under the supervision and with the participation of our management, including our chief executive officer and chief financial officer, of the effectiveness of the design and operation of our disclosure controls and procedures as of March 31, 2008. Based on that evaluation, our management, including our chief executive officer and chief financial officer, concluded that the disclosure controls and procedures were effective as of such date. There were no changes in internal control over financial reporting that occurred during our fiscal quarter ended March 31, 2008 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II

Item 1. Legal Proceedings.

     We are involved in various claims and legal actions in the ordinary course of business. In the opinion of management, the outcome of such ordinary course of business proceedings and litigation currently pending will not have a material adverse effect on our results of operations or financial results.

     You should see Part I, Item 3 of our Annual Report on Form 10-K for the year ended December 31, 2007 for more information about some of the proceedings and litigation in which we are involved.

Item 1A. Risk Factors.

     Our business inherently involves certain risks and uncertainties. The risks and uncertainties described below and in Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2007 are not the only ones we face. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also impair our business operations. Should one or more of any of these risks materialize, our business, financial condition, results of operations or liquidity could be materially adversely affected.

     We may incur losses as a result of certain marketing, trading and asset optimization strategies.

     We seek to optimize our coal production and leverage our knowledge of the coal industry through a variety of marketing, trading and other asset optimization strategies. We maintain a system of complementary processes and controls designed to monitor and control our exposure to market and other risks as a consequence of these strategies. These processes and controls seek to balance our ability to profit from certain marketing, trading and asset optimization strategies with our exposure to potential losses. While we employ a variety of risk monitoring and mitigation techniques, those techniques and accompanying judgments cannot anticipate every potential outcome or the timing of such outcomes. In addition, the processes and controls that we use to manage our exposure to market and other risks resulting from these strategies involve assumptions about the degrees of correlation or lack thereof among prices of various assets or other market indicators. These correlations may change significantly in times of market turbulence or other unforeseen circumstances. As a result, we may experience volatility in our earnings as a result of our marketing, trading and asset optimization strategies.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds.

     In September 2006, our board of directors authorized a share repurchase program for the purchase of up to 14,000,000 shares of our common stock. There is no expiration date on the current authorization, and we have not made any decisions to suspend or cancel purchases under the program. As of March 31, 2008, we have purchased 1,562,400 shares of our common stock under this program. We did not purchase any shares of our common stock under this program during the quarter ended March 31, 2008. Based on the closing price of our common stock as reported on the New York Stock Exchange on May 6, 2008, the approximate dollar value of our common stock that may yet be purchased under this program was $793.4 million.

Item 3. Defaults Upon Senior Securities.

     None.

Item 4. Submission of Matters to a Vote of Security Holders.

     Our annual meeting of stockholders was held on April 24, 2008 in the lower level auditorium at our headquarters at One CityPlace Drive, St. Louis, Missouri to elect James R. Boyd, John W. Eaves, Douglas H. Hunt and A. Michael Perry as directors for a three-year term ending at the annual meeting of our stockholders in 2011 and to ratify the appointment of Ernst & Young LLP as our independent public accounting firm.
