Notes to Condensed Consolidated Financial Statements
(unaudited)
1. Basis of Presentation
     The accompanying unaudited condensed consolidated financial statements include the accounts of Arch Western Resources, LLC and its subsidiaries and controlled entities (the “Company”). Arch Coal, Inc. (“Arch Coal”) has a 99.5% common membership interest in the Company, while BP p.l.c. has a 0.5% common membership interest and a preferred membership interest in the Company. The terms of the Company’s membership agreement grant a put right to BP p.l.c., where BP p.l.c. may require Arch Coal to purchase its membership interest. The terms of the agreement state that the price of the membership interest shall be determined by mutual agreement between the members. 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 and six month periods ended June 30, 2010 are not necessarily indicative of results to be expected for the year ending December 31, 2010. 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, 2009 included in the Company’s Annual Report on Form 10-K filed with the U.S. Securities and Exchange Commission.
2. Accounting Policies
     There are no new accounting pronouncements whose adoption is expected to have a material impact on the Company’s condensed consolidated financial statements.
3. Inventories
     Inventories consist of the following:
                 
    June 30,     December 31,  
    2010     2009  
    (In thousands)  
Coal
  $ 41,099     $ 42,316  
Repair parts and supplies, net of allowance
    112,854       123,334  
 
           
 
  $ 153,953     $ 165,650  
 
           
     The repair parts and supplies are stated net of an allowance for slow-moving and obsolete inventories of $13.3 million at June 30, 2010, and $12.6 million at December 31, 2009.
4. Debt
     On March 25, 2010, the Company entered into an amendment to its commercial paper program which decreased the maximum aggregate principal amount of the program to $75 million from $100 million. The commercial paper program is supported by a line of credit that expires on April 30, 2011.
5. Fair Values of Financial Instruments
     The following methods and assumptions were used by the Company in estimating its fair value disclosures for financial instruments:
     Cash and cash equivalents: At June 30, 2010 and December 31, 2009, the carrying amounts of cash and cash equivalents approximate fair value.
     Debt: The fair value of the Company’s debt, including commercial paper, was $1,014.4 million and $992.3 million at June 30, 2010 and December 31, 2009, respectively. Fair values are based upon observed prices in active markets when available or from valuation models using market information.
6. Comprehensive Income (Loss)
     Comprehensive income (loss) consists of net income (loss) and other comprehensive income (loss). Other comprehensive income (loss) items are transactions recorded in membership interests during the year, excluding net income and transactions with members.

7. Related Party Transactions
     Transactions with Arch Coal may not be at arm’s length. If the transactions were negotiated with an unrelated party, the impact could be material to the Company’s results of operations.
     The Company’s cash transactions are managed by Arch Coal. Cash paid to or from the Company that is not considered a distribution or a contribution is recorded in an Arch Coal receivable account. In addition, any amounts owed between the Company and Arch Coal are recorded in the account. At June 30, 2010 and December 31, 2009 the receivable from Arch Coal was approximately $1.7 billion and $1.5 billion, respectively. This amount earns interest from Arch Coal at the prime interest rate. Interest earned on the note was $13.9 million and $11.6 million for the three months ended June 30, 2010 and 2009, respectively, and $25.8 million and $23.3 million for the six months ended June 30, 2010 and 2009, respectively. The receivable is payable on demand; however, it is currently management’s intention to not demand payment of the receivable within the next year. Therefore, the receivable is classified on the accompanying condensed consolidated balance sheets as noncurrent, except for the anticipated payment referenced in Note 10, “Subsequent Event.”
     The Company is a party to Arch Coal’s accounts receivable securitization program. Under the program, the Company sells its receivables to Arch Coal without recourse at a discount based on the prime interest rate and days sales outstanding. During the three months ended June 30, 2010 and 2009, the Company sold $405.5 million and $322.5 million, respectively, of trade accounts receivable to Arch Coal at a total discount of $1.0 million and $0.8 million, respectively. During the six months ended June 30, 2010 and 2009, the Company sold $817.3 million and $707.6 million, respectively, of trade accounts receivable to Arch Coal at a discount of $1.9 million and $1.8 million, respectively. These transactions are recorded through the Arch Coal receivable account.
     For the three month periods ended June 30, 2010 and 2009, the Company incurred production royalties of $20.8 million and $9.9 million, respectively, payable to Arch Coal under sublease agreements. For the six month periods ended June 30, 2010 and 2009, the Company incurred production royalties of $38.9 million and $21.2 million, respectively, payable to Arch Coal under sublease agreements.
     The Company is charged selling, general and administrative services fees by Arch Coal. Expenses are allocated based on Arch Coal’s best estimates of proportional or incremental costs, whichever is more representative of costs incurred by Arch Coal on behalf of the Company. Amounts allocated to the Company by Arch Coal were $11.4 million and $7.2 million for the three months ended June 30, 2010 and 2009, respectively, and $19.2 million and $17.1 million for the six months ended June 30, 2010 and 2009, respectively. Such amounts are reported as selling, general and administrative expenses in the accompanying condensed consolidated statements of income.
8. 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 estimable. 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 condensed consolidated financial condition, results of operations or liquidity of the Company.
9. Segment Information
     The Company has two reportable business segments, which are based on the major low-sulfur coal basins in which the Company operates. Both of these reportable business segments include 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,

Table of Contents

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, and the Western Bituminous (WBIT) segment, with operations in Utah, Colorado and southern Wyoming.
     Operating segment results for the three and six month periods ended June 30, 2010 and 2009 are presented below. Results for the operating segments include all direct costs of mining. Corporate, Other and Eliminations includes corporate overhead, other support functions, and the elimination of intercompany transactions.
     The asset amounts below represent an allocation of assets used in the segments’ cash-generating activities. The amounts in the Corporate, Other and Eliminations represent primarily intercompany receivables.

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 regulations relating to mine safety; 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, 2009.
Overview
     We are a subsidiary of Arch Coal, Inc., one of the largest coal producers in the United States. We sell substantially all of our coal to power plants and industrial facilities. Our two reportable business segments are based on the low-sulfur U.S. coal producing regions in which we operate — the Powder River Basin and the Western Bituminous 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 region 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. In addition, Powder River Basin coal is generally lower in heat content, which requires some electric power generation facilities to blend it with higher Btu coal or retrofit some existing coal plants to accommodate lower Btu coal. The Western Bituminous region includes western Colorado, eastern Utah and southern Wyoming. Coal we mine from underground and surface mines in this region typically has a low sulfur content and varies in heat content.
     Favorable weather patterns, an improving U.S. economy, growth in global coal demand, and declining domestic coal production are all positively impacting coal markets. We witnessed better market conditions during the second quarter of 2010, and we estimate that coal markets during the remainder of 2010 will continue to reflect improvement over the weak domestic steam coal markets that prevailed in 2009. Year-to-date U.S. power generation increased approximately 4% through the third week of July, in response to slowly improving domestic and international economic conditions, as well as cold winter/hot summer weather in most of the U.S. We estimate that U.S. steam coal demand will grow in 2010, fueled by growth in power generation and declining generator stockpile levels.
     We also expect positive price improvements in 2010 in the steam coal markets, due to improving demand. In addition to stronger demand in 2010, we expect steam coal markets to benefit from the crossover of high-quality steam coal into the metallurgical markets, and declining supply in the Eastern U.S. due to increasing regulatory pressures and degradation and depletion of the reserve base.
     We temporarily suspended production at our Dugout Canyon mine in Carbon County, Utah, on April 29, 2010 after an increase in carbon monoxide levels resulted from a heating event in a previously mined area. After permanently sealing the area, we resumed full coal production on May 21, 2010. On June 22, 2010, an ignition event at our longwall resulted in a second evacuation of all underground employees at the mine. In both events, all employees were safely evacuated. We rendered the atmosphere inert and in early August began to reestablish ventilation at the longwall. The resumption of mining is dependent upon the time required to ventilate the longwall area, determine the cause of the ignition, implement preventive measures, and secure an MSHA-approved longwall ventilation plan. We expect that the outages resulted in a loss of income of approximately $6.5 million during the quarter.

Results of Operations
     Three Months Ended June 30, 2010 Compared to Three Months Ended June 30, 2009
     Summary. Our results during the second quarter of 2010, when compared to the second quarter of 2009, were influenced primarily by higher operating margins stemming from the contribution of the Jacobs Ranch mining complex to us from Arch Coal on October 1, 2009 and improved geologic conditions at our West Elk mine in the Western Bituminous region.
     Revenues. The following table summarizes information about coal sales for the three months ended June 30, 2010 and compares it with the information for the three months ended June 30, 2009:
                                 
    Three Months Ended June 30   Increase (Decrease)
    2010   2009   Amount   %
    (Amounts in thousands, except per ton data and percentages)
Coal sales
  $ 481,478     $ 360,806     $ 120,672       33.4 %
Tons sold
    33,922       23,649       10,273       43.4 %
Coal sales realization per ton sold
  $ 14.19     $ 15.26     $ (1.07 )     (7.0 )%
     Coal sales increased in the second quarter of 2010 from the second quarter of 2009, primarily due to the contribution of the Jacobs Ranch mining complex to us from Arch Coal in the fourth quarter of 2009. Our coal sales realizations per ton were lower in the 2010 quarter due to lower realizations per ton in our Powder River Basin segment, as well as the impact on our average selling price of the higher Powder River Basin volumes. 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”.
     Costs, expenses and other. The following table summarizes costs, expenses and other components of operating income for the three months ended June 30, 2010 and compares them with the information for the three months ended June 30, 2009:

     Cost of coal sales. Our cost of coal sales increased in the second quarter of 2010 from the second quarter of 2009 primarily due to the higher sales volumes discussed above, which was partially offset by the impact of a lower average cost per ton sold. We have provided more information about our operating segments under the heading “Operating segment results”.
     Depreciation, depletion and amortization and amortization of acquired sales contracts, net. When compared with the second quarter of 2009, higher depreciation and amortization costs in the second quarter of 2010 resulted primarily from the impact of the contribution of the Jacobs Ranch mining complex to us in the fourth quarter of 2009.
     Selling, general and administrative expenses. Selling, general and administrative expenses represent expenses allocated to us from Arch Coal. Expenses are allocated based on Arch Coal’s best estimates of proportional or incremental costs, whichever is more representative of costs incurred by Arch Coal on our behalf.

Operating margin per ton sold (2)
  $ 3.09     $ (1.51 )   $ 4.60       304.6 %
 
(1)   Coal sales prices per ton exclude certain transportation costs that we pass through to our customers. We use these financial measures because we believe the amounts as adjusted better represent the coal sales prices we achieved within our operating segments. Since other companies may calculate coal sales prices per ton differently, our calculation may not be comparable to similarly titled measures used by those companies. For the three months ended June 30, 2010, transportation costs per ton were $0.09 for the Powder River Basin and $2.98 for the Western Bituminous region. For the three months ended June 30, 2009, transportation costs per ton were $0.05 for the Powder River Basin and $2.32 for the Western Bituminous region.
 
(2)   Operating margin per ton sold is calculated as coal sales revenues less cost of coal sales and depreciation, depletion and amortization divided by tons sold.
     Powder River Basin — The increase in sales volume in the Powder River Basin in the second quarter of 2010 when compared with the second quarter of 2009 resulted from the contribution of the Jacobs Ranch mining operations to us from Arch Coal on October 1, 2009. Decreases in sales prices during the second quarter of 2010 when compared with the second quarter of 2009 primarily reflect the roll-off of contracts committed when market conditions were more favorable, as well as the effect of lower pricing on market-index priced tons. On a per-ton basis, operating margins in the second quarter of 2010 increased from the second quarter of 2009 due to a decrease in per-ton costs, which offset the impact of the lower per-ton sales prices. The decrease in per-ton costs resulted from efficiencies achieved from combining the acquired Jacobs Ranch mining operations with our existing Black Thunder operations and our cost containment efforts, as well as a decrease in hedged diesel fuel costs.
     Western Bituminous — In the Western Bituminous region, despite the two production outages at the Dugout Canyon mine, sales volumes in the second quarter of 2010 increased when compared to the second quarter of 2009, when quality issues at the West Elk mining complex in Colorado resulted in the decision to decrease production levels at the mine. Despite the detrimental impact in 2009 on our per-ton realizations of selling coal with a higher ash content, our realizations increased only slightly in 2010, due to ongoing soft steam coal market conditions in the region and an unfavorable mix of customer contracts. Effective cost control in the region resulted in the higher per-ton operating margins in the second quarter of 2010. In the second quarter of 2010, we continued to mine in more favorable geologic conditions at West Elk. To address any future quality issues that could result from sandstone intrusions similar to those we encountered previously, we are building a preparation plant at the mine, to be completed in late August 2010.
     Net interest expense. The following table summarizes our net interest expense for the three months ended June 30, 2010 and compares it with the information for the three months ended June 30, 2009:

prime interest rate. The increase in interest income during the second quarter of 2010 when compared to the second quarter of 2009 resulted primarily from higher average receivable balance during 2010.
Liquidity and Capital Resources
       Liquidity and capital resources
     Our primary sources of cash are sales of our coal production to customers, borrowings under our commercial paper program and debt related to significant transactions. Excluding any significant business acquisitions, we generally satisfy our working capital requirements and fund capital expenditures and debt-service obligations with cash generated from operations, and if necessary, from Arch Coal. Arch Coal manages our cash transactions. Cash paid to or from us that is not considered a distribution or a contribution is recorded in an Arch Coal receivable account. The receivable balance earns interest from Arch Coal at the prime interest rate. We are also party to Arch Coal’s accounts receivable securitization program. Under the program, we sell our receivables to a subsidiary of Arch Coal without recourse at a discount based on the prime rate and days sales outstanding.
     We believe that cash generated from operations will be sufficient to meet working capital requirements, anticipated capital expenditures and scheduled debt payments for at least the next several years. We manage our exposure to changing commodity prices for our long-term coal contract portfolio through the use of long-term coal supply agreements. We enter into fixed price, fixed volume supply contracts with terms generally greater than one year with customers with whom we have historically had limited collection issues. Our ability to satisfy debt service obligations, to fund planned capital expenditures and to make acquisitions 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.
     Under Arch Coal’s accounts receivable securitization program, we sold $405.5 million of trade accounts receivable to Arch Coal during the second quarter of 2010, at a total discount of $1.0 million. During the second quarter of 2009, we sold $322.5 million of trade accounts receivable to Arch Coal, at a total discount of $0.8 million. During the first half of 2010, we sold $817.3 million of trade accounts receivable to Arch Coal, at a total discount of $1.9 million. During the first half of 2009, we sold $707.6 million of trade accounts receivable to Arch Coal, at a total discount of $1.8 million.
     On March 25, 2010, we entered into an amendment to our commercial paper program which decreased the maximum aggregate principal amount of the program to $75 million from $100 million. The commercial paper program is supported by a line of credit that expires on April 30, 2011. We had commercial paper outstanding of $62.0 million at June 30, 2010 and $49.5 million at December 31, 2009. Our commercial paper placement program provides short-term financing at rates that are generally lower than the rates available under our revolving credit facility.
     Our subsidiary, Arch Western Finance LLC, has outstanding an aggregate principal amount of $950.0 million of 6.75% senior notes due on July 1, 2013. The notes are guaranteed by AWR and certain of its subsidiaries and are secured by an intercompany note from AWR to Arch Coal, Inc. The indenture under which the notes were issued contains certain restrictive covenants that limit AWR’s ability to, among other things, incur additional debt, sell or transfer assets and make certain investments. The notes may be redeemed as follows: at 101.125% of par for notes redeemed between July 1, 2010 and June 30, 2011, and 100% for notes redeemed on or after July 1, 2011.
     On August 5, 2010, we gave notice of our intent to redeem $500.0 million aggregate principal amount of our outstanding 6.75% senior notes on September 9, 2010 at a redemption price of 101.125%. We expect to fund this redemption with cash transferred from Arch Coal in the form of a loan of approximately $225.0 million and a repayment of a portion of our balance receivable from Arch Coal.

     The following is a summary of cash provided by or used in each of the indicated types of activities:
                 
    Six Months Ended June 30
    2010   2009
    (in thousands)
Cash provided by (used in):
               
Operating activities
  $ 196,408     $ 55,699  
Investing activities
    (184,094 )     (23,881 )
Financing activities
    13,373       (27,052 )
     Cash provided by operating activities increased in the first half of 2010 compared to the first half of 2009, primarily as a result of our improved operating performance.
     We used $160.2 million more cash in investing activities for the first half of 2010 than in the first half of 2009, primarily due to an increase in amounts loaned to Arch Coal, partially offset by a decrease in capital expenditures.
     Cash provided by financing activities was $13.4 million during the first half of 2010, compared to cash used in financing activities of $27.1 million during the first half of 2009. In 2009, we repaid a net $26.9 million under our commercial paper program. As a result of the poor credit markets, we had been unable to issue commercial paper up to the maximum amount allowed under the program. We have since reduced the maximum allowed under the program to $75 million from $100 million, as discussed previously, but during the first half of 2010, we increased the amount of commercial paper issued by $12.5 million to $62.0 million.
Critical Accounting Policies
     For a description of our critical accounting policies, see “Critical Accounting Policies” under Item 7 of our Annual Report on Form 10-K for the year ended December 31, 2009. There have been no significant changes to our critical accounting policies during the three months ended June 30, 2010.
Item 3.   Quantitative and Qualitative Disclosures About Market Risk.
     We manage our commodity price risk for our long-term coal contract portfolio through the use of long-term coal supply agreements. The majority of our tonnage is sold under long-term contracts. We are also exposed to price risk related to the value of sulfur dioxide emission allowances that are a component of quality adjustment provisions in many of our coal supply contracts. We manage this risk through the use of long-term coal supply agreements.
     We are also exposed to the risk of fluctuations in cash flows related to our purchase of diesel fuel. We use approximately 40 to 45 million gallons of diesel fuel annually in our operations. Arch Coal enters into heating oil swaps and options to reduce volatility in the price of diesel fuel for our operations. The swap agreements essentially fix the price paid for diesel fuel by requiring us to pay a fixed heating oil price and receive a floating heating oil price. The call options protect against increases in diesel fuel by granting us the right to participate in increases in heating oil prices. The cash settlements related to these swaps and options are allocated to us through the Arch Coal intercompany account.
     We are exposed to market risk associated with interest rates due to our existing level of indebtedness. At June 30, 2010, with the exception of our outstanding commercial paper, all of our outstanding debt bore interest at fixed rates.
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 June 30, 2010. 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 quarter ended June 30, 2010 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II
OTHER INFORMATION
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.
Item 1A.   Risk Factors.
     Our business inherently involves certain risks and uncertainties. The risks and uncertainties described in Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2009 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.
Item 2.   Unregistered Sales of Equity Securities and Use of Proceeds.
     None
Item 3.   Defaults Upon Senior Securities.
     None
Item 4.   Reserved
Item 5.   Other Information.
     We believe that our operations are some of the safest coal producers in the world. Safety is a core value at our parent company, Arch Coal, and at each of its subsidiary operations. We have in place a comprehensive safety program that includes extensive health & safety training for all employees, site inspections, emergency response preparedness, crisis communications training, incident investigation, regulatory compliance training and process auditing, as well as an open dialogue between all levels of employees. The goals of our processes are to eliminate exposure to hazards in the workplace, ensure that we comply with all mine safety regulations, and support regulatory and industry efforts to improve the health and safety of our employees along with the industry as a whole.
     Under the recently enacted 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 our 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”). Below we present the following items regarding certain mining safety and health matters, broken down by mining complex owned and operated by Arch Western Resources, LLC or our subsidiaries, for the three-month period ended June 30, 2010:
    Total number of violations of mandatory health or safety standards that could significantly and substantially contribute to the cause and effect of a coal or other mine safety or health hazard under section 104 of the Mine Act for which we have received a citation from MSHA;
 
    Total number of orders issued under section 104(b) of the Mine Act;
 
    Total number of citations and orders for unwarrantable failure of the mine operator to comply with mandatory health or safety standards under Section 104(d) of the Mine Act;
 
    Total number of imminent danger orders issued under section 107(a) of the Mine Act; and
 
    Total dollar value of proposed assessments from MSHA under the Mine Act.

(1)   MSHA assigns an identification number to each coal mine and may or may not assign separate identification numbers to related facilities such as preparation plants. We are providing the information in this table by mining complex rather than MSHA identification number because we believe this format will be more useful to investors than providing information based on MSHA identification numbers. For descriptions of each of these mining operations, please refer to the descriptions under Item 1. Business, in Part I of our Annual Report on Form 10-K for the fiscal year ended December 31, 2009.
 
(2)   Amounts included under the heading “Proposed MSHA Assessments” are the total dollar amounts for proposed assessments received from MSHA on or before August 4, 2010, for citations and orders occurring during the three-month period ended June 30, 2010.
     For the three-month period ended June 30, 2010, none of our mining complexes received written notice from MSHA of (i) a flagrant violation under section 110(b)(2) of the Mine Act; (ii) a pattern of violations of mandatory health or safety standards that are of such nature as could have significantly and substantially contributed to the cause and effect of coal or other mine health or safety hazards under section 104(e) of the Mine Act; or (iii) the potential to have such a pattern. For the three-month period ended June 30, 2010, we experienced no fatalities.
     As of June 30, 2010, we have a total of forty-four matters pending before the Federal Mine Safety and Health Review Commission. This includes legal actions that were initiated prior to the three-month period ended June 30, 2010 and which do not necessarily relate to the citations, orders or proposed assessments issued by MSHA during such three month period.
     In evaluating the above information regarding mine safety and health, investors should take into account factors such as: (i) the number of citations and orders will vary depending on the size of a coal mine, (ii) the number of citations issued will vary from inspector to inspector and mine to mine, and (iii) citations and orders can be contested and appealed, and during that process are often reduced in severity and amount, and are sometimes dismissed.
