PEABODY ENERGY CORPORATION
NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
JUNE 30, 2006
(dollars in thousands, except share data and where indicated)
(1) Basis of Presentation
     The consolidated financial statements include the accounts of the Company and its controlled affiliates. All intercompany transactions, profits, and balances have been eliminated in consolidation.
     Effective February 22, 2006, the Company implemented a two-for-one stock split on all shares of its common stock. The Company had a similar two-for-one stock split on March 30, 2005. All share and per share amounts in these unaudited condensed consolidated financial statements and related notes reflect the stock splits.
     The accompanying condensed consolidated financial statements as of June 30, 2006 and for the three and six months ended June 30, 2006 and 2005, and the notes thereto, are unaudited. However, in the opinion of management, these financial statements reflect all normal, recurring adjustments necessary for a fair presentation of the results of the periods presented. The balance sheet information as of December 31, 2005 has been derived from the Company’s audited consolidated balance sheet. The results of operations for the three and six months ended June 30, 2006 are not necessarily indicative of the results to be expected for future quarters or for the year ending December 31, 2006. Certain amounts in prior periods have been reclassified to conform to the report classifications as of June 30, 2006 and for the three and six months ended June 30, 2006, with no effect on previously reported net income or stockholders’ equity.
(2) New Accounting Pronouncements
     In June 2006, the Financial Accounting Standards Board (“FASB”) issued Interpretation 48 “Accounting for Uncertainty in Income Taxes – an interpretation of FASB Statement No. 109” (“FIN 48”). This interpretation prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. FIN 48 also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. This interpretation is effective for fiscal years beginning after December 15, 2006 (January 1, 2007 for the Company). Any adjustments required upon the adoption of this interpretation must be recorded directly to retained earnings in the year of adoption and reported as a change in accounting principle. The Company is currently evaluating the impact of this interpretation on its financial statements.
(3) Significant Transactions and Events
Gains on Disposal or Exchange of Assets
     In June 2006, the Company exchanged with the Bureau of Land Management approximately 63 million tons of leased coal reserves at its Caballo mining operation for approximately 46 million tons of coal reserves contiguous with our North Antelope Rochelle mining operation. Based on the fair value of the coal reserves exchanged, the Company recognized a gain on assets exchanged totaling $39.2 million. This non-cash transaction is excluded from the investing section of the statement of cash flows.
     In June 2005, the Company recognized an aggregate $12.5 million gain from property sales involving non-strategic coal assets and properties. As a result of the property transactions, asset retirement obligations were reduced by $9.2 million. Also, during the six months ended June 30, 2005, the Company sold its remaining 0.838 million Penn Virginia Resource Partners, L.P. (“PVR”) units for net proceeds of $41.9 million and recognized a $31.1 million gain on the sale.
Contract Losses
     During the six months ended June 30, 2005, the Company recorded contract losses of approximately $21.5 million, primarily related to breach of a coal supply contract by a producer. The contractual dispute was subsequently fully resolved during the three months ended September 30, 2005.

(4) Inventories
     Inventories consisted of the following:
                 
    June 30,     December 31,  
    2006     2005  
Saleable coal
  $ 73,245     $ 64,274  
Materials and supplies
    77,587       65,942  
Raw coal
    16,284       14,033  
Advance stripping
          245,522  
 
           
Total
  $ 167,116     $ 389,771  
 
           
     Advance stripping consisted of the costs to remove overburden above an unmined coal seam as part of the surface mining process. In March 2005, the Emerging Issues Task Force (“EITF”) issued EITF Issue No. 04-6, “Accounting for Stripping Costs in the Mining Industry” (“EITF Issue No. 04-6”). EITF Issue No. 04-6 and its interpretations require stripping costs incurred during a period to be attributed only to the inventory costs of the coal that is extracted during that same period. The Company adopted EITF Issue No. 04-6 on January 1, 2006 and utilized the cumulative effect adjustment approach whereby the cumulative effect adjustment reduced retained earnings by $150.3 million, net of tax. This non-cash item is excluded from the operating section of the statement of cash flows. Advance stripping costs are no longer included as a separate component of inventory.
(5) Assets and Liabilities from Coal Trading Activities
     The Company’s coal trading portfolio included forward contracts as of June 30, 2006 and December 31, 2005. The fair value of coal trading derivatives and related hedge contracts is set forth below:
                                 
    June 30, 2006     December 31, 2005  
    Assets     Liabilities     Assets     Liabilities  
Forward contracts
  $ 84,692     $ 67,223     $ 146,596     $ 131,988  
Other
          7,048             385  
 
                       
Total
  $ 84,692     $ 74,271     $ 146,596     $ 132,373  
 
                       
     Ninety-nine percent of the contracts in the Company’s trading portfolio as of June 30, 2006 were valued utilizing prices from over-the-counter market sources, adjusted for coal quality and traded transportation differentials, and 1% of the Company’s contracts were valued based on similar market transactions.
     As of June 30, 2006, the estimated future realization of the value of the Company’s trading portfolio was as follows:
         
Year of   Percentage
Expiration   of Portfolio
2006
    51 %
2007
    14 %
2008
    30 %
2009
    5 %
 
       
 
    100 %
 
       
     At June 30, 2006, 51% of the Company’s credit exposure related to coal trading activities was with investment grade counterparties and 49% was with non-investment grade counterparties, which were primarily other coal producers. The Company’s coal trading operations traded 18.1 million tons and 8.5 million tons for the three months ended June 30, 2006 and 2005, respectively, and 28.8 million tons and 17.7 million tons for the six months ended June 30, 2005 and 2004, respectively.

     In July 2005, the Company’s Board of Directors authorized a share repurchase program of up to 5% of the then outstanding shares of its common stock, or approximately 13.1 million shares. The repurchases may be made from time to time based on an evaluation of the Company’s outlook and general business conditions, as well as alternative investment and debt repayment options. In March 2006, the Company repurchased 250,000 of its common shares at a cost of $11.5 million.
Adoption of SFAS No. 123 (revised 2004), “Share-Based Payment”
     On December 16, 2004, the FASB issued Statement of Financial Accounting Standard (“SFAS”) No. 123 (revised 2004), “Share-Based Payment” (“SFAS No. 123(R)”), which is a revision of SFAS No. 123, “Accounting for Stock-Based Compensation” (“SFAS No. 123”). SFAS No. 123(R) supersedes Accounting Principles Board (“APB”) Opinion No. 25, “Accounting for Stock Issued to Employees” (“APB Opinion No. 25”) and amends SFAS No. 95, “Statement of Cash Flows.” Generally, the approach in SFAS No. 123(R) is similar to the approach described in SFAS No. 123. However, SFAS No. 123(R) requires all share-based payments to employees, including employee stock options, to be recognized ratably over the vesting period in the income statement based on their fair values at the grant date.
     The Company adopted SFAS No. 123(R) on January 1, 2006 and used the modified prospective method, in which compensation cost is recognized beginning with the effective date (a) based on the requirements of SFAS No. 123(R) for all share-based payments granted or modified after the effective date and (b) based on the requirements of SFAS No. 123 for all awards granted to employees prior to the effective date of SFAS No. 123(R) that remain unvested on the effective date. Prior to January 1, 2006, the Company had elected to apply APB Opinion No. 25 and related interpretations in accounting for its stock option plans, as permitted under SFAS No. 123 and SFAS No. 148 “Accounting for Stock-Based Compensation-Transition and Disclosure.” Beginning in 2006, SFAS No. 123(R) also requires that income tax benefits from stock options exercised be recorded as financing cash inflow on the statements of cash flows. The excess income tax benefit from stock option exercises during 2005 is included in operating cash flows, netted in deferred tax activity.
     As part of its share-based compensation program, the Company utilizes restricted stock, nonqualified stock options, an employee stock purchase plan and performance units (discussed further below). The Company began utilizing restricted stock as part of its equity-based compensation strategy in January 2005. Accounting for restricted stock awards was not changed by the adoption of SFAS No. 123(R). The Company recognized $1.1 million and $0.2 million of expense, net of taxes, for the three months ended June 30, 2006 and 2005, respectively, and $2.1 million and $0.5 million of expense, net of taxes, for the six months ended June 30, 2006 and 2005, respectively, related to restricted stock. For share-based payment instruments excluding restricted stock, the Company recognized $6.0 million (or $0.02 per diluted share) and $3.6 million (or $0.01 per diluted share) of expense, net of taxes, for the three months ended June 30, 2006 and 2005, respectively, and $12.4 million (or $0.05 per diluted share) and $6.6 million (or $0.02 per diluted share) of expense, net of taxes, for the six months ended June 30, 2006 and 2005, respectively. As a result of adopting SFAS 123(R), the Company’s net income for the three and six months ended June 30, 2006 was $1.6 million (or $0.01 per diluted share) and $1.2 million (or under $0.01 per diluted share) higher, respectively, than if it had continued to account for share-based compensation under APB Opinion No. 25. Share-based compensation expense is recorded in selling and administrative expenses in the condensed consolidated income statements. The Company used the Black-Scholes option pricing model to determine the fair value of stock options and employee stock purchase plan share-based payments made before and after the adoption of SFAS No. 123(R). As of June 30, 2006, the total unrecognized compensation cost related to nonvested awards was $33.6 million, net of taxes, which is expected to be recognized over 5.0 years with a weighted-average period of 1.3 years.

     Stock Options
     Employee and director stock options granted since the Company’s initial public offering (“IPO”) of common stock in May 2001 generally vest ratably over three years and expire after 10 years from the date of the grant, subject to earlier termination upon discontinuation of an employee’s service. Options granted prior to the IPO generally cliff vest between 2007 and 2010. Of the 9.8 million options outstanding at June 30, 2006, 4.1 million options cliff vest in November 2007. Option grants are typically made in January of each year. The Company granted 0.5 million options during the six months ended June 30, 2006, with a fair value of approximately $16.90 per option. These options were granted in the first quarter of 2006. The fair value of each option grant is estimated on the date of grant using the Black-Scholes option-pricing model with the following weighted-average assumptions used for grants in 2006 and 2005, respectively; dividend yield of 0.8% and 1.0%; expected volatility (based on historical volatility) of 36% and 40%; risk-free interest rate of 4.3% and 3.6%; and an expected life of 5.3 years and 5.7 years. The Company recognized $1.2 million and $2.3 million of expense, net of taxes, for the three and six months ended June 30, 2006, related to stock options.
     A summary of option activity under the plans as of June 30, 2006 is as follows:
                                 
                    Weighted    
            Weighted   Average   Aggregate
    Six Months   Average   Remaining   Intrinsic

    2,941,813     $ 8.51       6.5     $ 139.0  
 
                               
During the six months ended June 30, 2006, the total intrinsic value of options exercised, defined as the excess fair value of the underlying stock over the exercise price of the options, was $66.2 million.
     Employee Stock Purchase Plan
     During 2001, the Company adopted an employee stock purchase plan. Eligible full-time and part-time employees are able to contribute up to 15% of their base compensation into this plan, subject to a limit of $25,000 per year. Employees are able to purchase Company common stock at a 15% discount to the lower of the fair market value of the Company’s common stock on the initial or ending dates of each six-month offering period. Offering periods begin on January 1 and July 1 of each year. The fair value of the six-month “look-back” option in the Company’s employee stock purchase plan is estimated by adding the fair value of 0.15 of one share of stock to the fair value of 0.85 of an option on one share of stock. The Company recognized $0.3 million and $0.6 million of expense, net of taxes, for the three month and six month periods ended June 30, 2006, respectively, related to its employee stock purchase plan.
     Performance Units
     Performance units, which are typically granted annually in January by the Company, vest over a three year measurement period, subject to the achievement of performance goals and stock price performance at the conclusion of the three years. Three performance unit grants were outstanding during 2005 (the 2003, 2004 and 2005 grants) and 2006 (the 2004, 2005 and 2006 grants). The payout related to the 2003 grant (which was settled in cash in February 2006) was based on the Company’s stock price performance compared to both an industry peer group and an S&P Index. The payouts related to the 2004 grant (which will be settled in cash in February 2007) and 2005 and 2006 grants (which will be settled in common stock in 2008 and 2009, respectively) are based 50% on stock price performance compared to both an industry peer group and an S&P Index (a “market condition” under SFAS No. 123(R)) and 50% on a return on capital target (a “performance condition” under SFAS No. 123(R)). The Company granted 0.2 million performance units during the six months ended June 30, 2006. Under APB Opinion No. 25, all of the performance unit awards were accounted for as variable awards. Under SFAS No. 123(R), the awards settled in cash are accounted for as liability awards, and the awards settled in common stock are accounted for based on their grant date fair value. The performance condition awards were valued utilizing the grant date fair values of the Company’s stock adjusted for dividends forgone during the vesting period. The market condition awards were valued utilizing a Monte Carlo simulation which incorporates the total shareholder return hurdles set for each grant. The assumptions used in the valuations of the 2005 and 2006 grants, respectively: dividend yield of 0.8% and 1.0%; expected volatility of 36% and 40%; and risk-free interest rate of 4.25% and 3.25%. The Company

recognized $4.5 million and $3.6 million of expense, net of taxes, for the three months ended June 30, 2006 and 2005, respectively, and $9.5 million and $6.6 million of expense, net of taxes, for the six months ended June 30, 2006 and 2005, respectively, related to performance units.
     As noted above, prior to adopting SFAS No. 123(R), the Company applied APB Opinion No. 25 and related interpretations to account for its equity incentive plans. The following table reflects 2005 pro forma net income and basic and diluted earnings per share had compensation cost been determined for the Company’s non-qualified and incentive stock options based on the fair value at the grant dates consistent with the methodology set forth under SFAS No. 123:

Increase (decrease) in fair value of cash flow hedges, net of tax provision (benefit) of $8,870 and ($6,755) for the three months ended June 30, 2006 and 2005, respectively, and $10,113 and $13,073 for the six months ended June 30, 2006 and 2005, respectively
    13,306       (10,133 )     15,170       19,610  
 
                       
Comprehensive income
  $ 166,740     $ 85,121     $ 298,826     $ 166,754  
 
                       
     Comprehensive income differs from net income by the amount of unrealized gain or loss resulting from valuation changes of the Company’s cash flow hedges (which include fuel and natural gas hedges, currency forwards, and interest rate swaps) during the period. Changes in interest rates; crude, heating oil and natural gas prices; and the U.S. dollar/Australian dollar exchange rate affect the valuation of these instruments.

  $ 6,583     $ 7,077     $ 13,167     $ 24,079  
 
                       
Curtailment
     The curtailment loss occurring during the six months ended June 30, 2005 resulted from the termination of operations at two of the three operating mines that participate in the Western Surface UMWA Pension Plan (the “Plan”) during 2005. The loss is actuarially determined and consists of an increase in the actuarial liability, the accelerated recognition of previously unamortized prior service cost and contractual termination benefits under the Plan resulting from the termination of operations.
Contributions
     The Company previously disclosed in its financial statements for the year ended December 31, 2005 that it expected to contribute $6.6 million to its funded pension plans and make $1.3 million in expected benefit payments attributable to its unfunded pension plans during 2006. As of June 30, 2006, $0.6 million of expected benefit payments attributable to the unfunded pension plans were made and $1.6 million in contributions were made to the funded pension plans.
Components of Net Periodic Postretirement Benefit Costs
     Net periodic postretirement benefit costs included the following components:

Cash Flows
     The Company expects to pay $86.2 million attributable to its postretirement benefit plans during 2006, which reflects an increase of $11.2 million from its previously disclosed amount in the financial statements for the year ended December 31, 2005. This increase in expected payments includes approximately $3 million of refunds under a dispute resolution relating to payments made by retirees over the last 6 years; and the remainder relates to higher than anticipated costs and utilization. As of June 30, 2006, payments of $41.6 million attributable to the Company’s postretirement benefit plans were made.

(9) Segment Information
     The Company reports its operations primarily through the following reportable operating segments: “Western U.S. Mining,” “Eastern U.S. Mining,” “Australian Mining” and “Trading and Brokerage.” Western U.S. Mining operations reflect the aggregation of the Powder River Basin, Southwest and Colorado operating segments, and Eastern U.S. Mining operations reflect the aggregation of the Appalachia and Midwest operating segments. The principal business of the Western U.S. Mining, Eastern U.S. Mining and Australian Mining segments is the mining, preparation and sale of steam coal, sold primarily to electric utilities, and metallurgical coal, sold to steel and coke producers. Western U.S. Mining operations are characterized by predominantly surface mining extraction processes, lower sulfur content and Btu of coal, and longer shipping distances from the mine to the customer. Conversely, Eastern U.S. Mining operations are characterized by a majority of underground mining extraction processes, higher sulfur content and Btu of coal, and shorter shipping distances from the mine to the customer. Geologically, Western operations mine bituminous and subbituminous coal deposits, and Eastern operations mine bituminous coal deposits. Australian Mining operations are characterized by surface and underground extraction processes, mining primarily low sulfur, high Btu coal sold to an international customer base. The Trading and Brokerage segment’s principal business is the marketing, brokerage and trading of coal. “Corporate and Other” includes selling and administrative expenses, net gains on property disposals, costs associated with past mining obligations, joint venture earnings related to the Company’s 25.5% investment in a Venezuelan mine and revenues and expenses related to the Company’s other commercial activities such as coalbed methane, generation development and resource management.
     The Company’s chief operating decision maker uses Adjusted EBITDA as the primary measure of segment profit and loss. Adjusted EBITDA is defined as income from operations before deducting net interest expense, income taxes, minority interests, asset retirement obligation expense and depreciation, depletion and amortization.
     Operating segment results for the three and six months ended June 30, 2006 and 2005 are as follows:

Commitments
     As of June 30, 2006, purchase commitments for capital expenditures were $102.7 million and federal coal reserve lease payments due over the next three years totaled $534.6 million.
Oklahoma Lead Litigation
     Gold Fields Mining, LLC (“Gold Fields”), one of the Company’s subsidiaries, is a dormant, non-coal producing entity that was previously managed and owned by Hanson PLC, a predecessor owner of the Company. In a February 1997 spin-off, Hanson PLC transferred ownership of Gold Fields to the Company, despite the fact that Gold Fields had no ongoing operations and the Company had no prior involvement in its past operations. The Company has agreed to indemnify a former affiliate of Gold Fields for certain claims. A predecessor of Gold Fields formerly operated two lead mills near Picher, Oklahoma prior to the 1950s and mined, in accordance with lease agreements and permits, approximately 1.5% of the total amount of the ore mined in the county.
     Gold Fields and two other companies are defendants in two class action lawsuits. The plaintiffs have asserted claims predicated on allegations of intentional lead exposure by the defendants and are seeking compensatory damages, punitive damages and the implementation of medical monitoring and relocation programs for the affected individuals. Gold Fields is also a defendant, along with other companies, in several personal injury lawsuits involving over 50 children, arising out of the same lead mill operations. Plaintiffs in these actions are seeking compensatory and punitive damages for alleged personal injuries from lead exposure. In December 2003, the Quapaw Indian tribe and certain Quapaw land owners filed a class action lawsuit against Gold Fields and five other companies. The plaintiffs are seeking compensatory and punitive damages based on a variety of theories. Gold Fields has filed a third-party complaint against the United States, and other parties. In February 2005, the state of Oklahoma on behalf of itself and several other parties sent a notice to Gold Fields and other companies regarding a possible natural resources damage claim. All of the lawsuits are pending in the U.S. District Court for the Northern District of Oklahoma.
     The outcome of litigation and these claims are subject to numerous uncertainties. Based on the Company’s evaluation of the issues and their potential impact, the amount of any future loss cannot be reasonably estimated. However, the Company believes this matter is likely to be resolved without a material adverse effect on the Company’s financial condition, results of operations or cash flows.
Navajo Nation
     On June 18, 1999, the Navajo Nation served three of the Company’s subsidiaries, including Peabody Western Coal Company (“Peabody Western”), with a complaint that had been filed in the U.S. District Court for the District of Columbia. The Navajo Nation has alleged 16 claims, including Civil Racketeer Influenced and Corrupt Organizations Act (“RICO”) violations and fraud. The complaint alleges that the defendants jointly participated in unlawful activity to obtain favorable coal lease amendments. The plaintiff is seeking various remedies including actual damages of at least $600 million, which could be trebled under the RICO counts, punitive damages of at least $1 billion, a determination that Peabody Western’s two coal leases have terminated due to Peabody Western’s breach of these leases and a reformation of these leases to adjust the royalty rate to 20%. Subsequently, the court allowed the Hopi Tribe to intervene in this lawsuit and the Hopi Tribe is also seeking unspecified actual damages, punitive damages and reformation of its coal lease. On March 4, 2003, the U.S.

Supreme Court issued a ruling in a companion lawsuit involving the Navajo Nation and the United States rejecting the Navajo Nation’s allegation that the United States breached its trust responsibilities to the Tribe in approving the coal lease amendments.
     On February 9, 2005, the U.S. District Court for the District of Columbia granted a consent motion to stay the litigation until further order of the court. Peabody Western, the Navajo Nation, the Hopi Tribe and the owners of the power plants served by the suspended Black Mesa mine and the Kayenta mine are in mediation with respect to this litigation and other business issues.
     The outcome of litigation, or the current mediation, is subject to numerous uncertainties. Based on the Company’s evaluation of the issues and their potential impact, the amount of any future loss cannot be reasonably estimated. However, the Company believes this matter is likely to be resolved without a material adverse effect on the Company’s financial condition, results of operations or cash flows.
The Future of the Mohave Generating Station and Black Mesa Mine
     The Company had been supplying coal to the Mohave Generating Station pursuant to a long-term coal supply agreement through its Black Mesa Mine. The mine terminated operations on December 31, 2005, and the coal supply agreement expired on that date. As a part of the alternate dispute resolution referenced in the Navajo Nation litigation, Peabody Western has been participating in mediation with the owners of the Mohave Generating Station and the Navajo Generating Station and the two tribes to resolve the complex issues surrounding groundwater and other disputes involving the two generating stations. On June 19, 2006, the owners of the Mohave Generating Station announced that they were halting efforts to reopen the plant and that they would try to sell it. There is no assurance that the Mohave Generating Station will resume operations. The Mohave plant was the sole customer of the Black Mesa Mine, which sold 4.6 million tons of coal in 2005. During 2005, the mine generated $29.8 million of Adjusted EBITDA, which represented 3.4% of the Company’s total 2005 Adjusted EBITDA of $870.4 million.
Salt River Project Agricultural Improvement and Power District — Mine Closing and Retiree Health Care
     Salt River Project and the other owners of the Navajo Generating Station filed a lawsuit on September 27, 1996, in the Superior Court of Maricopa County in Arizona seeking a declaratory judgment that certain costs relating to final reclamation, environmental monitoring work and mine decommissioning and costs primarily relating to retiree health care benefits are not recoverable by the Company’s subsidiary, Peabody Western, under the terms of a coal supply agreement dated February 18, 1977. The contract expires in 2011. The trial court subsequently ruled that the mine decommissioning costs were subject to arbitration but that the retiree health care costs were not subject to arbitration. The Company has recorded a receivable for mine decommissioning costs of $75.4 million and $74.2 million included in “Investments and other assets” in the condensed consolidated balance sheets as of June 30, 2006 and December 31, 2005, respectively.
     The outcome of litigation and arbitration is subject to numerous uncertainties. Based on the Company’s evaluation of the issues and their potential impact, the amount of any future loss cannot be reasonably estimated. However, the Company believes this matter is likely to be resolved without a material adverse effect on its financial condition, results of operations or cash flows.
Gulf Power Company Litigation
     On June 21, 2006, a Company subsidiary filed a complaint in the U.S. District Court, Southern District of Illinois, seeking a declaratory judgment upholding its declaration of a permanent force majeure under a coal supply agreement with Gulf Power Company. On June 22, 2006, Gulf Power Company filed a breach of contract lawsuit against the Company’s subsidiary in the U.S. District Court, Northern District of Florida, contesting the force majeure declaration and seeking damages for alleged past and future tonnage shortfalls of nearly 5 million tons under the coal supply agreement, which would have expired on December 31, 2007. The parties have filed motions to determine which court will hear the lawsuits.
     The outcome of these lawsuits is subject to numerous uncertainties. Based on the Company’s evaluation of the issues and their potential impact, the amount of any future loss cannot reasonably be estimated. However, the Company believes this matter is likely to be resolved without a material adverse effect on its financial condition, results of operations or cash flows.

Environmental
     The Company is subject to federal, state and local environmental laws and regulations, including the Comprehensive Environmental Response, Compensation and Liability Act of 1980, as amended (“CERCLA” or “Superfund”), the Superfund Amendments and Reauthorization Act of 1986, the Clean Air Act, the Clean Water Act and the Conservation and Recovery Act. Superfund and similar state laws create liability for investigation and remediation in response to releases of hazardous substances in the environment and for damages to natural resources. Under that legislation and many state Superfund statutes, joint and several liability may be imposed on waste generators, site owners and operators and others regardless of fault. These regulations could require the Company to do some or all of the following:
    remove or mitigate the effects on the environment at various sites from the disposal or release of certain substances;
 
    perform remediation work at such sites; and
 
    pay damages for loss of use and non-use values.
     Environmental claims have been asserted against Gold Fields related to activities of Gold Fields or its former affiliates. Gold Fields has been named a potentially responsible party (“PRP”) based on CERCLA at five sites, and claims have been asserted at 18 other sites. The number of PRP sites in and of itself is not a relevant measure of liability, because the nature and extent of environmental concerns varies by site, as does Gold Fields’ estimated share of responsibility.
     The Company’s policy is to accrue environmental cleanup-related costs of a non-capital nature when those costs are believed to be probable and can be reasonably estimated. The quantification of environmental exposures requires an assessment of many factors, including the nature and extent of contamination, the timing, extent and method of the remedial action, changing laws and regulations, advancements in environmental technologies, the quality of information available related to specific sites, the assessment stage of each site investigation, preliminary findings and the length of time involved in remediation or settlement. The Company also assesses the financial capability and proportional share of costs of other PRPs and, where allegations are based on tentative findings, the reasonableness of the Company’s apportionment. The Company has not anticipated any recoveries from insurance carriers in the estimation of liabilities recorded in its consolidated balance sheets. Undiscounted liabilities for environmental cleanup-related costs for all of the sites noted above totaled $42.2 million as of June 30, 2006 and $42.5 million as of December 31, 2005, $23.3 million and $23.6 million of which was reflected as a current liability, respectively. These amounts represent those costs that the Company believes are probable and reasonably estimable. In September 2005, Gold Fields and other PRPs received a letter from the U.S. Department of Justice alleging that the PRPs’ mining operations caused the Environmental Protection Agency (“EPA”) to incur approximately $125 million in residential yard remediation costs at Picher, Oklahoma and will cause the EPA to incur additional remediation costs relating to historic mining sites. Gold Fields has participated in the ongoing settlement discussions. A predecessor of Gold Fields formerly operated two lead mills near Picher, Oklahoma prior to the 1950s and mined, in accordance with lease agreements and permits, approximately 1.5% of the total amount of the ore mined in the county. Gold Fields believes it has meritorious defenses to these claims. Gold Fields is involved in other litigation in the Picher area, and the Company has agreed to indemnify one of the defendants in this litigation as discussed under the “Oklahoma Lead Litigation” caption above. Significant uncertainty exists as to whether claims will be pursued against Gold Fields in all cases, and where they are pursued, the amount of the eventual costs and liabilities, which could be greater or less than this provision.
     Although waste substances generated by coal mining and processing are generally not regarded as hazardous substances for the purposes of Superfund and similar legislation, some products used by coal companies in operations, such as chemicals, and the disposal of these products are governed by the statute. Thus, coal mines currently or previously owned or operated by the Company, and sites to which the Company has sent waste materials, may be subject to liability under Superfund and similar state laws.
Other
     In addition, the Company at times becomes a party to other claims, lawsuits, arbitration proceedings and administrative procedures in the ordinary course of business. Management believes that the ultimate resolution of such other pending or threatened proceedings is not reasonably likely to have a material effect on the financial position, results of operations or liquidity of the Company.

(11) Guarantees
     In the normal course of business, the Company is a party to the following guarantees:
     The Company owns a 30.0% interest in a partnership that leases a coal export terminal from the Peninsula Ports Authority of Virginia under a 30-year lease that permits the partnership to purchase the terminal at the end of the lease term for a nominal amount. The partners have severally (but not jointly) agreed to make payments under various agreements which in the aggregate provide the partnership with sufficient funds to pay rents and to cover the principal and interest payments on the floating-rate industrial revenue bonds issued by the Peninsula Ports Authority, and which are supported by letters of credit from a commercial bank. As of June 30, 2006, the Company’s maximum reimbursement obligation to the commercial bank is in turn supported by a letter of credit totaling $42.8 million.
     The Company has guaranteed the performance of Asset Management Group (“AMG”) under its coal purchase contract with a third party, which has terms extending through December 31, 2006. Default occurs if AMG does not deliver specified monthly tonnage amounts to the third party. In the event of a default, the Company would assume AMG’s obligation to ship coal at agreed prices for the remaining term of the contract. As of June 30, 2006, the maximum potential future payments under this guarantee are approximately $1.5 million, based on recent spot coal prices. As a matter of recourse in the event of a default, the Company has access to cash held in escrow and the ability to trigger an assignment of AMG’s assets to the Company. Based on these recourse options and the remote probability of non-performance by AMG due to its prior operating history, the Company has valued the liability associated with the guarantee at zero.
     As part of arrangements through which the Company obtains exclusive sales representation agreements with small coal mining companies (the “Counterparties”), the Company issued financial guarantees on behalf of the Counterparties. These guarantees facilitate the Counterparties’ efforts to obtain bonding or financing. The Company also guaranteed bonding for a partnership in which it formerly held an interest. The total amount guaranteed by the Company was $6.3 million, and the fair value of the guarantees recognized as a liability was $0.4 million as of June 30, 2006. The Company’s obligations under the guarantees extend to September 2015. In March 2006, the Company issued a guarantee for certain equipment lease arrangements on behalf of one of the sales representation parties with maximum potential future payments totaling $3.1 million and with lease terms that extend to April 2010. The Company has multiple recourse options in the event of default, including the ability to assume the lease and procure use of the equipment or to settle the lease and take title to the assets. If default occurs, the Company has the ability and intent to exercise its recourse options, so the liability associated with the guarantee has been valued at zero.
     The Company is the lessee under numerous equipment and property leases. It is common in such commercial lease transactions for the Company, as the lessee, to agree to indemnify the lessor for the value of the property or equipment leased, should the property be damaged or lost during the course of the Company’s operations. The Company expects that losses with respect to leased property would be covered by insurance (subject to deductibles). The Company and certain of its subsidiaries have guaranteed other subsidiaries’ performance under their various lease obligations. Aside from indemnification of the lessor for the value of the property leased, the Company’s maximum potential obligations under its leases are equal to the respective future minimum lease payments and assume that no amounts could be recovered from third parties. The Company has also guaranteed certain of its subsidiaries’ performance under contracts related to the development of coal-fueled generating projects.
     The Company has provided financial guarantees under certain long-term debt agreements entered into by its subsidiaries, and substantially all of the Company’s subsidiaries provide financial guarantees under long-term debt agreements entered into by the Company. The maximum amounts payable under the Company’s debt agreements are equal to the respective principal and interest payments. Supplemental guarantor/non-guarantor financial information is provided in Note 12.

(12) Supplemental Guarantor/Non-Guarantor Financial Information
     In accordance with the indentures governing the 6.875% Senior Notes due 2013 and the 5.875% Senior Notes due 2016, certain wholly-owned U.S. subsidiaries of the Company have fully and unconditionally guaranteed the 6.875% Senior Notes and the 5.875% Senior Notes, on a joint and several basis. Separate financial statements and other disclosures concerning the Guarantor Subsidiaries are not presented because management believes that such information is not material to the holders of the 6.875% Senior Notes and the 5.875% Senior Notes. The following unaudited condensed historical financial statement information is provided for the Guarantor/Non-Guarantor Subsidiaries.

(13) Subsequent Event
     The Company entered into a Merger Implementation Agreement, dated as of July 6, 2006 (the “Merger Implementation Agreement”), with Excel Coal Limited (“Excel”). The Merger Implementation Agreement contemplates that a wholly-owned subsidiary of the Company will acquire Excel by means of a scheme of arrangement transaction under Australian law (the “Transaction”), pursuant to which the Company will pay A$8.50 per share (US$6.21) for all outstanding shares of Excel, representing a total acquisition price of approximately US$1.34 billion plus assumed debt of approximately US$190 million. The Transaction is subject to the satisfaction or waiver of certain closing conditions, including approval of the Transaction by an Australian court, approval of the Transaction by Excel shareholders, as well as other conditions outlined in the Merger Implementation Agreement.
          The Company expects to finance the Transaction with a combination of available cash, a draw on its credit facility, and/or the proceeds from the issuance of debt or equity securities. The Company has obtained commitments for up to US$1.5 billion of senior unsecured loans. The Company does not intend to draw down on this bridge financing unless funds from the contemplated equity or debt offerings are unavailable at the time of closing. Closing is targeted for early in the fourth quarter 2006.

Table of Contents

     When considering these forward-looking statements, you should keep in mind the cautionary statements in this document and in our other Securities and Exchange Commission (“SEC”) filings, including the more detailed discussion of these factors, as well as other factors that could affect our results, contained in Item 1A, Risk Factors of our 2005 Annual Report on Form 10-K. We do not undertake any obligation to update these statements, except as required by federal securities laws.
Overview
     We are the largest private sector coal company in the world, with majority interests in 34 active coal operations located throughout all major U.S. coal producing regions and internationally in Australia. In the first six months of 2006, we sold 122.1 million tons of coal. In 2005, we sold 239.9 million tons of coal that accounted for an estimated 21.5% of all U.S. coal sales, and were approximately 70% greater than the sales of our closest domestic competitor and 49% more than our closest international competitor. Based on Energy Information Administration (“EIA”) estimates, demand for coal in the United States was more than 1.1 billion tons in 2005, and domestic consumption of coal is expected to grow at a rate of 1.7% per year through 2030 when U.S. coal demand is forecasted to be 1.8 billion tons. The EIA expects demand for coal use at coal-to-liquids (“CTL”) plants to grow to 190 million tons by 2030. Coal-fueled generation is used in most cases to meet baseload electricity requirements, and coal use generally grows at the approximate rate of electricity growth, which is expected to average 1.6% annually through 2025. Coal production located west of the Mississippi River is projected to provide most of the incremental growth as Western production increases to an estimated 63% share of total production in 2030. In 2004, coal’s share of electricity generation was approximately 51%, a share that the EIA projects will grow to 57% by 2030.
     Our primary customers are U.S. utilities, which accounted for 87% of our sales in 2005. We typically sell coal to utility customers under long-term contracts (those with terms longer than one year). During 2005, approximately 90% of our sales were under long-term contracts. As of June 30, 2006, we expect full year 2006 production of 230 to 240 million tons and total sales of 255 to 265 million tons. As discussed more fully in Item 1A, Risk Factors, in our 2005 Annual Report on Form 10-K, our results of operations in the near term could be negatively impacted by poor weather conditions, unforeseen geologic conditions or equipment problems at mining locations, and by the availability of transportation for coal shipments. On a long-term basis, our results of operations could be impacted by our ability to secure or acquire high-quality coal reserves, find replacement buyers for coal under contracts with comparable terms to existing contracts, or the passage of new or expanded regulations that could limit our ability to mine, increase our mining costs, or limit our customers’ ability to utilize coal as fuel for electricity generation. In the past, we have achieved production levels that are relatively consistent with our projections.
     We conduct business through four principal operating segments: Western U.S. Mining, Eastern U.S. Mining, Australian Mining, and Trading and Brokerage. Our Western U.S. Mining operations consist of our Powder River Basin, Southwest and Colorado operations, and our Eastern U.S. Mining operations consist of our Appalachia and Midwest operations. The principal business of the Western U.S. Mining segment is the mining, preparation and sale of steam coal, sold primarily to electric utilities. The principal business of the Eastern U.S. Mining segment is the mining, preparation and sale of steam coal, sold primarily to electric utilities, as well as the mining of some metallurgical coal, sold to steel and coke producers.
     Geologically, Western operations mine bituminous and subbituminous coal deposits and Eastern operations mine bituminous coal deposits. Our Western U.S. Mining operations are characterized by predominantly surface extraction processes, lower sulfur content and Btu of coal, and higher customer transportation costs (due to longer shipping distances). Our Eastern U.S. Mining operations are characterized by predominantly underground extraction processes, higher sulfur content and Btu of coal, and lower customer transportation costs (due to shorter shipping distances).
     Australian Mining operations are characterized by both surface and underground extraction processes, mining primarily low-sulfur, high Btu coal sold to an international customer base. On July 6, 2006, we entered into a Merger Implementation Agreement to acquire Excel Coal Limited, or Excel. Under the merger agreement we will pay A$8.50 per share (US$6.21) for all outstanding shares of Excel, representing a total acquisition price of approximately US$1.34 billion plus assumed debt of approximately US$190 million. The transaction is subject to the satisfaction or waiver of certain closing conditions, including approval of the transaction by an Australian court, approval of the transaction by Excel shareholders, as well as other conditions outlined in the agreement. Excel has more than 500 million tons of metallurgical and thermal coal reserves. Excel’s operations produced approximately 5.6 million tons of coal in 2005, and they are expected to produce up to 15 million tons in 2007 and up to 20 million tons in 2008.

     We own a 25.5% interest in Carbones del Guasare, which owns and operates the Paso Diablo Mine in Venezuela. The Paso Diablo Mine produces approximately 6 to 8 million tons of steam coal annually for export to the United States and Europe. Each of our mining operations is described in Item 1, Business, of our 2005 Annual Report on Form 10-K.
     Metallurgical coal is produced primarily from two of our Australian mines and two of our U.S. mines. Metallurgical coal is approximately 5% of our total sales volume and approximately 3% of U.S. sales volume.
     In addition to our mining operations, which comprised 85% of revenues in 2005, our trading and brokerage operations (15% of revenues), transactions utilizing our vast natural resource position (selling non-core land holdings and mineral interests) and other ventures generate revenues and additional cash flows.
     We continue to pursue the development of coal-fueled generating projects in areas of the U.S. where electricity demand is strong and where there is access to land, water, transmission lines and low-cost coal. The projects involve mine-mouth generating plants using our surface lands and coal reserves. Our ultimate role in these projects could take numerous forms, including, but not limited to equity partner, contract miner or coal lessor. The projects we are currently pursuing include the 1,500-megawatt Prairie State Energy Campus in Washington County, Illinois and the 1,500-megawatt Thoroughbred Energy Campus in Muhlenberg County, Kentucky. The plants, assuming all necessary permits and financing are obtained and following selection of partners and sale of a majority of the output of each plant, could be operational following a four-year construction phase. In April 2006, we received a decision affirming the air permit for our Thoroughbred Energy Campus. This milestone allows us to continue advancing the development of that campus. Certain parties subsequently challenged the favorable decision in Kentucky state court.
     The EIA projects that the high price of oil will lead to an increase in demand for unconventional sources of transportation fuel, including Btu conversion technologies, and that coal will increase its share as a fuel for generation of electricity. We have engaged in several Btu conversion projects which are designed to expand the uses of coal through various technologies, and we are continuing to explore options particularly as they relate to Btu conversion technologies such as coal-to-liquids and coal gasification.
     Effective February 22, 2006, we implemented a two-for-one stock split on all shares of our common stock. All share and per share amounts in this quarterly report on Form 10-Q reflect this split. In July 2005, our Board of Directors authorized a share repurchase program of up to 5% of the outstanding shares of our common stock. The repurchases may be made from time to time based on an evaluation of our outlook and general business conditions, as well as alternative investment and debt repayment options. In March 2006, we purchased 250,000 of our common shares at a cost of $11.5 million. On January 23, 2006, our Board of Directors authorized a 26% increase in our dividend, to $0.06 per share, to shareholders of record on February 7, 2006.
Results of Operations
Adjusted EBITDA
     The discussion of our results of operations below includes references to, and analysis of our segments’ Adjusted EBITDA results. Adjusted EBITDA is defined as income from continuing operations before deducting net interest expense, income taxes, minority interests, asset retirement obligation expense and depreciation, depletion and amortization. Adjusted EBITDA is used by management primarily as a measure of our segments’ operating performance. Because Adjusted EBITDA is not calculated identically by all companies, our calculation may not be comparable to similarly titled measures of other companies. Adjusted EBITDA is reconciled to its most comparable measure, under generally accepted accounting principles, in Note 9 to our unaudited condensed consolidated financial statements.

Three Months Ended June 30, 2006 Compared to the Three Months Ended June 30, 2005
Summary
     Our second quarter 2006 revenues of $1.32 billion increased 18.7% over the second quarter of the prior year. The increase in revenues was driven by improved pricing in nearly all of our mining operations as well as demand-driven increases in volumes in the Powder River Basin, Midwest and Australia. For the quarter, Segment Adjusted EBITDA of $295.2 million reflects an 11.6% increase over the prior year, primarily due to increases in sales prices at our U.S. and Australian Mining Operations. Delayed installation and start up of new longwall equipment reduced the results of both our Western and Australian operating segments in the second quarter of 2006, and additional longwall moves at our Appalachian operations reduced our Eastern operating segment results. Also impacting our 2006 results are the termination of operations at our Black Mesa and Seneca mines, which occurred in late 2005. Net income was $153.4 million for the three months ended June 30, 2006, or $0.57 per share, an increase of 61.1% over 2005 net income of $95.3 million, or $0.36 per share.

     In the second quarter of 2006, our revenues were $1.32 billion, increasing by $207.6 million, or 18.7%, compared to prior year. This increase in revenues was primarily caused by demand-driven increases to sales prices in all regions, but particularly in the metallurgical coal markets of Australia and Appalachia. In the second quarter 2006, sales prices in our U.S. mining operations increased $1.04 per ton, or 6.4%, and sales prices in our Australian operations increased $21.35 per ton, or 31.2%. This revenue increase was also affected by increased sales volumes in the Powder River Basin and Midwest operations.

Table of Contents

     Sales increased $203.8 million, or 18.7%, to $1.29 billion in 2006. Western U.S. Mining sales increased $23.4 million, Eastern U.S. Mining sales were $89.9 million higher, sales in Australian Mining improved $77.2 million and sales from our brokerage operations increased $13.3 million. Sales increased on improved pricing in every operating segment and through higher volumes in our Powder River Basin, Midwest and Australia operations. In most segments our average sales price per ton increased due to increased demand for our coal products, but particularly in the regions where we produce metallurgical coal. We sell metallurgical coal from our Eastern U.S. and Australian Mining operations, and we sell ultra-low sulfur Powder River Basin coal from our Western U.S. Mining operations.
     Sales increased in our Western U.S. Mining operations due to higher volumes at our Powder River Basin operations, partially offset by the impacts from the delayed installation and start up of new longwall equipment at our Twentymile Mine and the termination of operations at our Black Mesa and Seneca mines in late 2005. Sales at our Powder River Basin operations improved $57.3 million due to increased sales volumes and prices. Powder River Basin production and sales volumes were up as a result of strong demand for the mines’ low-sulfur product and improved rail conditions compared to 2005, when the region was dealing with train derailments and subsequent rail maintenance. Sales at our Colorado operations decreased $23.9 million primarily due to the above mentioned start up delays at our Twentymile Mine, and sales at our Southwest operations were down $10.0 million mainly due to the termination of operations at our Black Mesa Mine. The increase in Eastern U.S. Mining operations’ sales was primarily due to improved pricing for both steam and metallurgical coal from the region and higher sales volumes in the Midwest operations. Sales in Appalachia increased $53.1 million, or 24.8% and sales in the Midwest increased $36.8 million, or 17.4%. On average, prices in our Eastern U.S. Mining operations increased 10.4% to $36.70 per ton and, as discussed above, were mainly driven by increases in metallurgical coal prices. Production increased in the Midwest mainly due to newly developed mines that began operation in late 2005. Additional longwall moves at one mine, along with geologic and equipment issues at contract miner operations resulted in lower production at our Appalachia operations. Sales from our Australian Mining operations increased $77.2 million, or 55.0%. The increase in Australian sales was due primarily to a 31.2% increase in per ton sales prices, largely due to higher international metallurgical coal prices. Brokerage operations’ sales increased $13.3 million in 2006 compared to prior year due to an increase in average per ton sales prices.
     Other revenues increased $3.8 million, or 19.8%, compared to prior year primarily due to proceeds from a producer buy-out of a coal purchase contract and higher trading results, partially offset by customers idling their synthetic fuel plants, which became uneconomical as crude oil prices rose above certain levels.
Segment Adjusted EBITDA
     Our total segment Adjusted EBITDA was $295.2 million for the second quarter of 2006, compared with $264.5 million in the prior year, detailed as follows.

     Adjusted EBITDA from our Western U.S. Mining operations decreased $5.7 million during 2006 reflecting an average margin per ton decrease of $0.29 per ton, partially offset by an increase in sales volume of 2.1 million tons. The decrease in Adjusted EBITDA was primarily due to delayed installation and start up of new longwall equipment at our Twentymile Mine partially offset by improved sales volume at our Powder River Basin operations. The conditions at Twentymile Mine resulted in lower production and higher costs for power, materials and labor, representing a 69% increase in costs per ton for the mine. This decrease was partially offset by higher sales volumes of 4.9 million tons in the Powder River Basin due to improved rail conditions compared to 2005. The Powder River Basin operations have continued to experience rail delays in 2006 due to rail maintenance; however, the impact of these delays is less in 2006 as compared to 2005. The Powder River operations also experienced increased unit costs that resulted from higher fuel costs, lower than anticipated volume due to

rail and weather-related difficulties and an increase in revenue-based royalties and production taxes. Adjusted EBITDA for our Southwest operations was similar to prior year results, but reflected lower volumes due to the termination of operations at the Black Mesa Mine in late 2005 offset by lower costs in 2006 due to a $13.4 million charge in 2005 to provide an allowance for disputed receivables.
     Eastern U.S. Mining operations’ Adjusted EBITDA increased $12.2 million, or 12.7%, compared to prior year primarily due to an increase in margin per ton of $0.39, or 5.4% and higher sales volumes. Appalachia operations’ Adjusted EBITDA increased $8.6 million, or 16.3%, as a result of sales price increases and improved production at one mine upon overcoming certain geologic conditions in the prior year. This increase in Appalachian operations’ Adjusted EBITDA was partially offset by lower production at one mine due to geologic and equipment issues, and higher costs at another mine associated with longwall moves. Results in our Midwest operations improved $3.6 million, or 8.4%, compared to prior year as benefits of higher prices, product mix and higher volumes were partially offset by higher costs due to fuel and explosives costs and lower margins related to the idling of the synthetic fuel plants.
     Our Australian Mining operations’ Adjusted EBITDA increased $18.4 million in the current year, a 38.9% increase compared to prior year due to an increase of $4.07, or 17.6%, in margin per ton and an increase in tons sold. Our Australian operations mainly benefited from increased sales prices, which helped overcome higher costs at our underground mine. In the second quarter of 2006, we installed and placed into operation new longwall equipment at our underground mine.
     Trading and Brokerage operations’ Adjusted EBITDA increased $5.8 million from the prior year due to proceeds from a producer buy-out of a coal purchase contract and higher trading results.

     Income before income taxes and minority interests of $151.9 million for the quarter is $46.0 million, or 43.4%, higher than prior year primarily due to improved segment Adjusted EBITDA as discussed above. Corporate and Other Adjusted EBITDA results include selling and administrative expenses, equity income from our Venezuelan joint venture, net gains on asset disposals or exchanges, costs associated with past mining obligations and revenues and expenses related to our other commercial activities such as coalbed methane, generation development, Btu conversion, and resource management. The $32.3 million decrease in Corporate and Other Adjusted EBITDA (net expense) in 2006 compared to 2005 was mainly due to a $33.6 million increase in net gains on the disposal or exchange of assets. In the second quarter of 2006, we recorded a $39.2 million gain on exchange of coal reserves (see Note 3), partially offset by the higher amount of net gains from the sale of non-strategic land and coal reserves in 2005 compared to 2006.
     Depreciation, depletion and amortization increased $12.2 million in 2006 due to higher production and capital expenditures in 2006 and higher amortization in 2006 compared to 2005 due to the amortization of contract liabilities in 2005 related to 2004 acquisitions.

The income tax benefit for the second quarter of 2006 related primarily to increased percentage depletion and a reduction in tax reserves resulting from the favorable finalization of former parent companies federal tax audits, partially offset by higher pretax earnings in 2006.
Six Months Ended June 30, 2006 Compared to the Six Months Ended June 30, 2005
Summary
     In the first six months of 2006, our revenues of $2.63 billion increased 20.2% over the prior year. Revenues were driven higher by improved pricing in nearly all of our mining operations as well as demand-driven increases in volumes in the Powder River Basin and Midwest. In the first six months of 2006, Segment Adjusted EBITDA of $619.5 million was a 31.3% increase over the prior year, primarily due to increases in sales prices at our U.S. and Australian Mining Operations. Delayed installation and start up of new longwall equipment reduced the results of both our Western and Australian operating segments in 2006, and additional longwall moves at our Appalachian operations reduced our Eastern operating segment results. Also impacting our 2006 results were the termination of operations at our Black Mesa and Seneca mines, which occurred in late 2005. Net income was $283.7 million for the six months ended June 30, 2006, or $1.05 per share, an increase of 92.8% over 2005 net income of $147.1 million, or $0.55 per share.

     In the first six months of 2006, our revenues were $2.63 billion, increasing by $441.9 million, or 20.2%, compared to prior year. This increase in revenues was primarily caused by increases to sales prices in all regions, but particularly in the metallurgical coal markets of Appalachia and Australia.
     Sales increased 20.0% to $2.58 billion in 2006. Western U.S. Mining sales increased $51.1 million, Eastern U.S. Mining sales were $178.9 million higher, sales in Australian Mining improved $126.8 million and sales from our brokerage operations increased $73.4 million. Sales increased on improved pricing in every operating segment and through higher volumes in our Powder River Basin and Midwest operations and our international brokerage business. Our average U.S. mining sales price per ton increased $1.34 per ton, or 8.3% in the first six months of 2006 compared to the prior year as strong demand continued for our coal products.
     Sales increased in our Western U.S. Mining operations due to higher volumes and prices at our Powder River Basin operations, partially offset by the impacts from the delayed installation and start up of new longwall equipment at our Twentymile Mine and by the impacts of the termination of operations at our Black Mesa and Seneca mines in late 2005. Overall, prices in our Western U.S. Mining operations increased 2.2% to $10.59 per ton. In the West, sales increased in the Powder River Basin, which improved $103.8 million due to increased sales volumes and prices. Powder River Basin production and sales volumes were up as a result of strong demand for the mines’ low-sulfur product and improved rail conditions compared to 2005. Sales decreased $24.0 million at our Colorado operations primarily due to the above mentioned start up delays at our Twentymile Mine and decreased $28.7 million at our Southwest operations due to the termination of operations at our Black Mesa Mine. The increase in Eastern U.S. Mining operations’ sales was primarily due to improved pricing for both steam and metallurgical coal from the region. Sales in Appalachia increased $91.5 million, or 21.7% and sales in the Midwest increased $87.4 million, or 20.8%. On average, prices in our Eastern U.S. Mining operations increased 12.5% to $37.08 per ton and, as discussed above, were mainly driven by increases in metallurgical coal prices. Production in our Appalachian operations was lower due to additional longwall moves at one of our mines along with geologic and equipment issues at contract miner operations. Production increased in the Midwest mainly due to newly developed mines that began operation in late 2005. Sales from our Australian Mining operations were $126.8 million, or 52.1%, higher than in 2005. The increase in Australian sales was due primarily to a 45.6% increase in per ton sales prices to $86.77 per ton, largely due to higher international metallurgical coal prices. Brokerage operations’ sales increased $73.4 million in 2006 compared to prior year due to an increase in average per ton sales prices and higher sales volumes.
     Other revenues increased $11.7 million, or 34.5%, compared to prior year primarily due to proceeds from a producer buy-out of a coal purchase contract and higher trading results, partially offset by customers idling their synthetic fuel plants.

     Adjusted EBITDA from our Western U.S. Mining operations increased $1.7 million during 2006 reflecting an increase in sales volume of 3.2 million tons, negatively impacted by a margin per ton decrease of $0.10. The increase in Adjusted EBITDA was driven by higher sales volumes of 7.2 million tons in the Powder River Basin due to improved rail conditions compared to 2005. The Powder River operations experienced increased unit costs that resulted from higher fuel costs, lower than anticipated volume due to rail and weather-related difficulties, and an increase in revenue-based royalties and production taxes. This increase in Adjusted EBITDA was partially offset by impacts from the delayed installation and start up of new longwall equipment at our Twentymile Mine, which resulted in lower production and a 64% cost per ton increase. Adjusted EBITDA for our Southwest operations was similar to prior year results, but reflected lower volumes due to the termination of operations at the Black Mesa Mine in late 2005 offset by lower costs due to a $13.4 million charge in 2005 to provide an allowance for disputed receivables.
     Eastern U.S. Mining operations’ Adjusted EBITDA increased $49.9 million, or 26.2%, compared to prior year primarily due to an increase in margin per ton of $1.36, or 18.7% and higher sales volumes. Appalachia operations’ Adjusted EBITDA increased $26.0 million, or 23.9%, as a result of sales price increases and improved production at one mine upon overcoming certain geologic conditions in the prior year, partially offset by lower production at one mine due to geologic issues and higher costs at another mine associated with longwall moves. Results in our Midwest operations were improved $23.9 million, or 29.2%, compared to prior year as benefits of higher volumes, product mix and prices were partially offset by higher costs due to higher fuel and explosives costs and lower margins related to customers idling their synthetic fuel plants. The six month 2006 results also included $8.9 million of income from a settlement related to customer billings regarding coal quality.
     Our Australian Mining operations’ Adjusted EBITDA increased $52.1 million in the current year, an 84.7% increase compared to prior year due to an increase of $11.58, or 77.1%, in margin per ton and an increase in tons sold. Our Australian operations produce mostly (75% to 85%) high margin metallurgical coal. Strong metallurgical coal sales prices led to improvements to our Australian results, but were limited by the impact of higher costs due to geological problems at our underground mine.
     Trading and Brokerage operations’ Adjusted EBITDA increased $43.8 million from the prior year. The 2005 results included a $14.1 million loss associated with the failure of a coal supplier to ship under a coal supply agreement (see Note 3). In 2006, trading and brokerage results include the producer contract buy-out, improved brokerage margins and increased volumes.

     Income before income taxes and minority interests of $298.3 million for the first six months of 2006 is $135.8 million, or 83.6%, higher than prior year primarily due to improved segment Adjusted EBITDA as discussed above.
     Corporate and Other Adjusted EBITDA results include selling and administrative expenses, equity income from our Venezuelan joint venture, net gains on asset disposals or exchanges, costs associated with past mining obligations and revenues and expenses related to our other commercial activities such as coalbed methane, generation development, Btu conversion, and resource management. The $8.9 million improvement in Corporate and Other primarily included higher gains on the disposal or exchange of assets of $11.7 million, higher income of $4.5 million in 2006 from our 25.5% interest in Carbones del Guasare, which owns and operates the Paso Diablo Mine in Venezuela, partially offset by an $8.9 million increase in selling and administrative expenses. The higher gains on disposal or exchange of assets of $11.7 million primarily related to a $39.2 million gain on exchange of coal reserves (see Note 3), partially offset by the recognition of a $31.1 million gain in 2005 from the sale of our remaining interest in PVR units.
     Selling and administrative expenses increased by $8.9 million primarily related to accruals for higher long-term performance-based incentive plans, the expensing of stock options required beginning January 1, 2006, and higher outside service costs primarily related to a significant upgrade in our enterprise resource planning system and costs of process and management improvement initiatives. To support continued growth and globalization of our businesses, we are converting our existing information systems across the major business processes to an integrated information technology system provided by SAP AG. The project began in the first quarter of 2006 and is expected to be completed in approximately two years.
     Depreciation, depletion and amortization increased $17.2 million in 2006 due to higher production and capital expenditures as well as higher amortization in 2006 compared to 2005 due to the amortization of contract liabilities in 2005 related to 2004 acquisitions.

     Net income increased $136.5 million compared to the first six months of 2006 due to the increase in income before income taxes and minority interests discussed above and a lower income tax provision, partially offset by an increase in minority interests. The lower income tax provision resulted from increased percentage depletion and a reduction in tax reserves resulting from the favorable finalization of former parent companies federal tax audits, partially offset by higher pre-tax income. Minority interests increased as a result of acquiring additional interest in a joint venture near the end of the first quarter of 2006.
Outlook
Events Impacting Near-Term Operations
     In the second quarter of 2006, we encountered delays in the installation and start up of new longwall equipment at our Twentymile Mine, which decreased production and operating results. Shipments from our Powder River Basin mines were impacted in the first half of 2006 by rail service disruptions related to ongoing operating issues even though these impacts were significantly less than the 2005 impacts of train derailments and subsequent problems. Rail carriers are expected to continue in-depth maintenance on their track throughout 2006. We expect higher shipment levels from our PRB operations in 2006 compared with 2005, but are cautious about our ability to reach targeted shipment levels.
     In the second quarter of 2006, our North Goonyella Mine in Australia installed and started-up new longwall equipment to increase operating performance. We expect that the new longwall equipment will assist in stabilizing some previously encountered adverse geologic issues, and near-term results may be impacted as we work toward optimizing the benefits of this new equipment. Also, in 2005 our Australian operations experienced delayed shipments and high demurrage costs due to port congestion and unpredictable vessel loading schedules. These shipping issues were aggravated by two cyclones in Eastern Australia in early 2006. Although port congestion has been reduced, demurrage costs and unpredictable timing of vessel loading could impact future results.
Long-term Overview
     Our outlook for the coal markets remains positive. We believe strong coal markets will continue worldwide, driven by growth in the U.S., Asia and other industrialized economies that are increasing coal demand.
     Strong demand for coal in the U.S. is being driven by the growing economy and high prices of natural gas and oil. The U.S. economy grew at an annual rate of 3.5% in 2005 and an annual rate of 2.5% in the second quarter of 2006 as reported by the U.S. Commerce Department. At June 30, 2006, both natural gas and oil prices remained at high levels. Natural gas prices exited a very mild 2005 winter at forward prices of $7 to $10 per million Btu, and world oil and gas production struggles to keep pace with demand. The U.S. Department of Energy’s National Energy Technology Laboratory reported that 153 coal-fueled generating plants have been announced or are in development. The EIA projects that the high price of oil will lead to an increase in demand for unconventional sources of transportation fuel, including Btu conversion technologies such as coal-to-liquids and coal gasification, and that coal will increase its share as a fuel for generation of electricity.

     Demand for Powder River Basin coal is increasing, particularly for our ultra-low sulfur products. The Powder River Basin represents more than half of our production, and the published reference price for high-Btu, ultra-low sulfur Powder River Basin coal has increased substantially in the past year. We control approximately 3.5 billion tons of proven and probable reserves in the Powder River Basin and we sold 68.0 million tons of coal from this region in the first half of 2006, an increase of 11.9% over the prior year.
     Global coal markets continue to grow, also driven by increased demand from growing economies. China’s economy grew 11.3% in the second quarter of 2006 as published by the National Bureau of Statistics of China. Metallurgical coal continues to sell at a significant premium to steam coal, and metallurgical markets remain strong as global steel production grew more than 8% through May 2006. We expect to capitalize on the strong global market for metallurgical coal primarily through production and sales of metallurgical coal from our Appalachia operations and our Australian operations. In response to growing international markets, we are establishing a European trading desk.
     We are targeting 2006 production of 230 million to 240 million tons and total sales volume of 255 million to 265 million tons, including 12 to 14 million tons of metallurgical coal. As of June 30, 2006, our unpriced volumes for produced tonnage were 60 to 70 million tons for 2007 and 130 to 140 million tons for 2008.
     Management expects strong market conditions and operating performance to overcome external cost pressures, geologic conditions and uncertain port and rail performance. We are experiencing increases in operating costs related to fuel, explosives, steel, tires, contract mining and healthcare, and have taken measures to mitigate the increases in these costs. In addition, historically low long-term interest rates also have a negative impact on expenses related to our actuarially determined, employee-related liabilities. We may also encounter poor geologic conditions, lower third party contract miner or brokerage source performance or unforeseen equipment problems that limit our ability to produce at forecasted levels. To the extent upward pressure on costs exceeds our ability to realize sales increases, or if we experience unanticipated operating or transportation difficulties, our operating margins would be negatively impacted. See “Cautionary Notice Regarding Forward-Looking Statements” for additional considerations regarding our outlook.
Liquidity and Capital Resources
     Our primary sources of cash include sales of our coal production to customers, cash generated from our trading and brokerage activities, sales of non-core assets and financing transactions, including the sale of our accounts receivable (through our securitization program). Our primary uses of cash include our cash costs of coal production, capital expenditures, interest costs and costs related to past mining obligations as well as planned acquisitions. Our ability to pay dividends, service our debt (interest and principal) and acquire new productive assets or businesses is dependent upon our ability to continue to generate cash from the primary sources noted above in excess of the primary uses. Future dividends, among other things, are subject to limitations imposed by our 6.875% Senior Notes, 5.875% Senior Notes and Senior Secured Credit Facility covenants. We expect to fund all of our capital expenditure requirements with cash generated from operations, and during 2005 and as of June 30, 2006 have had no borrowings outstanding under our $900.0 million revolving line of credit, which we use primarily for standby letters of credit. This provides us with available borrowing capacity ($493.5 million as of June 30, 2006) to use to fund strategic acquisitions or meet other financing needs. We were in compliance with all of the covenants of the Senior Secured Credit Facility, the 6.875% Senior Notes and the 5.875% Senior Notes as of June 30, 2006.
     Net cash provided by operating activities was $213.4 million for the six months ended June 30, 2006 compared to $253.6 million provided by operating activities for the six months ended June 30, 2005. The decrease was primarily related to the timing of working capital needs partially offset by stronger operational performance in 2006.
     Net cash used in investing activities was $349.2 million for the six months ended June 30, 2006 compared to $190.2 million used in the six months ended June 30, 2005. The increase reflects higher capital expenditures, the acquisition of an additional interest in a joint venture, and lower proceeds from the disposal of assets in 2006. The additional capital expenditures included longwall equipment and mine development at our Australian mines, longwall replacement at our Twentymile mine, the opening of new mines and upgrading of existing mines in the Midwest and Appalachia, and the purchase of expansion equipment. Many of these projects began in the fourth quarter of 2005. In the six months ended June 30, 2005, we acquired mining assets, including 70 million tons of Illinois and Indiana coal reserves, surface properties and equipment, from Lexington Coal Company for $61.0 million with cash used in investing activities including $56.5 million of the outlay as it related to reserves and equipment. Proceeds from the disposal of assets in 2005 primarily reflects the sale

of our remaining 0.838 million PVR units, while the 2006 proceeds primarily reflect the sale of non-strategic land and coal reserves.
     Net cash used in financing activities was $48.7 million during the six months ended June 30, 2006 compared to cash provided by financing activities of $6.3 million in the prior year. The 2006 long-term debt payments include a $19.2 million repayment of bank notes held by a majority-owned joint venture and the $7.7 million purchase of a portion of our 5.875% Senior Notes in the open market. In 2006, we repurchased 250,000 shares of our common stock under a Board approved repurchase program, utilizing $11.5 million. The 2006 activity compared to 2005 also reflects higher dividend payments of $12.2 million and lower proceeds from the exercise of stock options of $3.6 million. The 2005 activity includes an increase in the usage of our accounts receivable securitization program by $25.0 million.
     The 2006 financing activity also includes a $26.5 million tax benefit related to stock option exercises included in financing activity based on the newly adopted accounting standard for share-based compensation (see “Newly Adopted Accounting Pronouncements” below for more discussion about the adoption of this standard). In 2005, this tax benefit related to stock option exercises was included in operating activities.
     In the second quarter of 2006, Fitch Ratings upgraded the ratings on our senior secured term loan and revolving credit facility to BBB from BBB- and on our 6.875% Senior Notes and 5.875% Senior Notes due 2013 and 2016, respectively, to BBB- from BB+, citing our well-diversified operations, good control of low-cost production, strong liquidity and moderate leverage. In the first quarter of 2006, Moody’s Investor Services upgraded our corporate rating to Ba1 from Ba2 and the senior unsecured rating to Ba2 from Ba3. These security ratings reflect the views of the rating agency only. An explanation of the significance of these ratings may be obtained from the rating agency. Such ratings are not a recommendation to buy, sell or hold securities, but rather an indication of creditworthiness. Any rating can be revised upward or downward or withdrawn at any time by a rating agency if it decides that the circumstances warrant the change. Each rating should be evaluated independently of any other rating.
Transactions and Subsequent Events
     In July 2006, we entered into a merger agreement to acquire Excel. The merger agreement contemplates that one of our wholly-owned subsidiaries will acquire Excel by means of a scheme of arrangement transaction under Australian law, pursuant to which we will pay A$8.50 per share (US$6.21) for all outstanding shares of Excel, representing a total acquisition price of approximately US$1.34 billion plus assumed debt of approximately US$190 million. We expect to finance the transaction with a combination of available cash, a draw on our credit facility, and/or the proceeds from the issuance of debt or equity securities. We have obtained commitments for up to US$1.5 billion of senior unsecured loans. We do not intend to draw down on this bridge financing unless funds from the contemplated equity or debt offerings are unavailable at the time of closing. Closing is targeted for early in the fourth quarter 2006.
Contractual Obligations
     At June 30, 2006, we had $102.7 million of purchase obligations for capital expenditures and $534.6 million of obligations related to federal coal reserve lease payments due over the next three years. At June 30, 2006, total capital expenditures for 2006 are expected to range from $450 million to $525 million, excluding federal coal reserve lease payments. Approximately 60% of projected 2006 capital expenditures relates to replacement, improvement, or expansion of existing mines, particularly in Appalachia and the Midwest. Approximately $9 million of the expenditures relate to safety equipment that will be utilized to comply with recently issued federal and state regulations. The remainder of the expenditures relate to growth initiatives such as increasing capacity in the Powder River Basin. We anticipate funding these capital expenditures primarily through operating cash flow.

Off-Balance Sheet Arrangements
     In the normal course of business, we are a party to certain off-balance sheet arrangements. These arrangements include guarantees, indemnifications, financial instruments with off-balance sheet risk, such as bank letters of credit and performance or surety bonds and our accounts receivable securitization. Liabilities related to these arrangements are not reflected in our consolidated balance sheets, and we do not expect any material adverse effects on our financial condition, results of operations or cash flows to result from these off-balance sheet arrangements.
     In March 2000, we established an accounts receivable securitization program. Under the program, undivided interests in a pool of eligible trade receivables that have been contributed to our wholly-owned, bankruptcy-remote subsidiary are sold, without recourse, to a multi-seller, asset-backed commercial paper conduit (“Conduit”). Purchases by the Conduit are financed with the sale of highly rated commercial paper. We used proceeds from the sale of the accounts receivable to repay long-term debt, effectively reducing our overall borrowing costs. The securitization program is scheduled to expire in September 2009, and the maximum amount of undivided interests in accounts receivable that may be sold to the Conduit is $225.0 million. The securitization transactions have been recorded as sales, with those accounts receivable sold to the Conduit removed from the condensed consolidated balance sheet. The amount of undivided interests in accounts receivable sold to the Conduit was $225.0 million as of June 30, 2006 and December 31, 2005.
     In March 2006, we issued a guarantee for certain equipment lease arrangements with maximum potential future payments totaling $3.1 million at June 30, 2006 and with lease terms that extend to April 2010. There were no other material changes to our off-balance sheet arrangements during the six months ended June 30, 2006. See Note 11 to our unaudited condensed consolidated financial statements included in this report for a discussion of our guarantees. All off-balance sheet arrangements are also discussed in Management’s Discussion and Analysis of Financial Condition and Results of Operations in our 2005 Annual Report on Form 10-K.
Newly Adopted Accounting Pronouncements
     We adopted EITF Issue No. 04-6, “Accounting for Stripping Costs in the Mining Industry,” on January 1, 2006 and utilized the cumulative effect adjustment approach whereby a cumulative effect adjustment reduced retained earnings by $150.3 million, net of tax. EITF Issue No. 04-6 states “that stripping costs incurred during the production phase of a mine are variable production costs that should be included in the costs of the inventory produced during the period that the stripping costs are incurred.” Advance stripping costs include those costs necessary to remove overburden above an unmined coal seam as part of the surface mining process and prior to the adoption were included as the “work-in-process” component of “Inventories” in the consolidated balance sheet. EITF Issue No. 04-6 and its interpretations require stripping costs incurred during a period to be attributed only to the inventory costs of the coal that is extracted during that same period, and therefore, advance stripping costs are no longer included as a separate component of inventory.
     On January 1, 2006, we adopted Statement of Financial Accounting Standard (“SFAS”) No. 123 (revised 2004), “Share-Based Payment” (“SFAS No. 123(R)”), which is a revision of SFAS No. 123, “Accounting for Stock-Based Compensation” (“SFAS No. 123”). SFAS No. 123(R) supersedes Accounting Principles Board (“APB”) Opinion No. 25, “Accounting for Stock Issued to Employees” (“APB Opinion No. 25”) and amends SFAS No. 95, “Statement of Cash Flows.” Prior to January 1, 2006, we applied APB Opinion No. 25 and related interpretations in accounting for our stock option plans, as permitted under SFAS No. 123 and SFAS No. 148 “Accounting for Stock-Based Compensation-Transition and Disclosure”. We applied SFAS No. 123(R) through use of the modified prospective method, in which compensation cost is recognized beginning with the effective date (a) based on the requirements of SFAS No. 123(R) for all share-based payments granted or modified after the effective date and (b) based on the requirements of SFAS No. 123 for all awards granted to employees prior to the effective date of SFAS No. 123(R) that remain unvested on the effective date. SFAS No. 123(R) requires all share-based payments to employees, including grants of employee stock options, to be recognized in the income statement based on their fair values. SFAS No. 123(R) also requires that the excess income tax benefits from stock options exercised be recorded as financing cash inflow on the statements of cash flows. The excess income tax benefit from stock option exercises during 2005 is included in operating cash flows, netted in deferred tax activity.

     For share-based payment instruments excluding restricted stock, we recognized $6.0 million (or $0.02 per diluted share) and $3.6 million (or $0.01 per diluted share) of expense, net of taxes, for the three months ended June 30, 2006 and 2005, respectively, and $12.4 million (or $0.05 per diluted share) and $6.6 million (or $0.02 per diluted share) of expense, net of taxes, for the six months ended June 30, 2006 and 2005, respectively. As a result of adopting SFAS 123(R), our net income for the three and six months ended June 30, 2006 was $1.6 million (or $0.01 per diluted share) and $1.2 million (or under $0.01 per diluted share) higher, respectively, than if we had continued to account for share-based compensation under APB Opinion No. 25. We used the Black-Scholes option pricing model to determine the fair value of stock options and employee stock purchase plan share-based payments made before and after the adoption of SFAS No. 123(R). We began utilizing restricted stock as part of our equity-based compensation strategy in January 2005. Accounting for restricted stock awards was not changed by the adoption of SFAS 123(R). As of June 30, 2006, the total unrecognized compensation cost related to nonvested awards was $33.6 million, net of taxes, which is expected to be recognized over 5.0 years with a weighted-average period of 1.3 years. See Note 6 to our unaudited condensed consolidated financial statements for further discussion of our share-based compensation plans.
Item 3. Quantitative and Qualitative Disclosures About Market Risk.
     The potential for changes in the market value of our coal trading, interest rate and currency portfolios is referred to as “market risk.” Market risk related to our coal trading portfolio is evaluated using a value at risk analysis (described below). Value at risk analysis is not used to evaluate our non-trading interest rate and currency portfolios. A description of each market risk category is set forth below. We attempt to manage market risks through diversification, controlling position sizes, and executing hedging strategies. Due to lack of quoted market prices and the long term, illiquid nature of the positions, we have not quantified market risk related to our non-trading, long-term coal supply agreement portfolio.
Coal Trading Activities and Related Commodity Price Risk
     We engage in over-the-counter and direct trading of coal. These activities give rise to commodity price risk, which represents the potential loss that can be caused by an adverse change in the market value of a particular commitment. We actively measure, monitor and adjust traded position levels to remain within risk limits prescribed by management. For example, we have policies in place that limit the amount of total exposure, in value at risk terms, that we may assume at any point in time.
     We account for coal trading using the fair value method, which requires us to reflect financial instruments with third parties, such as forwards, options and swaps, at market value in our consolidated financial statements. Our trading portfolio included forwards as of June 30, 2006 and December 31, 2005.
     We perform a value at risk analysis on our coal trading portfolio, which includes over-the-counter and brokerage trading of coal. The use of value at risk allows us to quantify in dollars, on a daily basis, the price risk inherent in our trading portfolio. Value at risk represents the potential loss in value of our mark-to-market portfolio due to adverse market movements over a defined time horizon (liquidation period) within a specified confidence level. Our value at risk model is based on the industry standard variance/co-variance approach. This captures our exposure related to both option and forward positions. Our value at risk model assumes a 15-day holding period and a 95% one-tailed confidence interval. This means that there is a one in 20 statistical chance that the portfolio would lose more than the value at risk estimates during the liquidation period.
     The use of value at risk allows management to aggregate pricing risks across products in the portfolio, compare risk on a consistent basis and identify the drivers of risk. Due to the subjectivity in the choice of the liquidation period, reliance on historical data to calibrate the models and the inherent limitations in the value at risk methodology, we perform regular stress and scenario analysis to estimate the impacts of market changes on the value of the portfolio. The results of these analyses are used to supplement the value at risk methodology and identify additional market-related risks.
     We use historical data to estimate our value at risk and to better reflect current asset and liability volatilities. Given our reliance on historical data, value at risk is effective in estimating risk exposures in markets in which there are not sudden fundamental changes or shifts in market conditions. An inherent limitation of value at risk is that past changes in market risk factors may not produce accurate predictions of future market risk. Value at risk should be evaluated in light of this limitation.

Table of Contents

     During the six months ended June 30, 2006, the actual low, high and average values at risk for our coal trading portfolio were $1.0 million, $1.6 million and $1.3 million, respectively. As of June 30, 2006, the timing of the estimated future realization of the value of our trading portfolio was as follows:
         
Year of   Percentage
Expiration   of Portfolio
2006
    51 %
2007
    14 %
2008
    30 %
2009
    5 %
 
       
 
    100 %
 
       
     We also monitor other types of risk associated with our coal trading activities, including credit, market liquidity and counterparty nonperformance.
Credit Risk
     Our concentration of credit risk is substantially with energy producers and marketers and electric utilities. Our policy is to independently evaluate each customer’s creditworthiness prior to entering into transactions and to constantly monitor the credit extended. In the event that we engage in a transaction with a counterparty that does not meet our credit standards, we will protect our position by requiring the counterparty to provide appropriate credit enhancement. When appropriate (as determined by our credit management function), we have taken steps to reduce our credit exposure to customers or counterparties whose credit has deteriorated and who may pose a higher risk of failure to perform under their contractual obligations. These steps include obtaining letters of credit or cash collateral, requiring prepayments for shipments or the creation of customer trust accounts held for our benefit to serve as collateral in the event of a failure to pay. To reduce our credit exposure related to trading and brokerage activities, we seek to enter into netting agreements with counterparties that permit us to offset receivables and payables with such counterparties. Counterparty risk with respect to interest rate swap and foreign currency forwards and options transactions is not considered to be significant based upon the creditworthiness of the participating financial institutions.
Foreign Currency Risk
     We utilize currency forwards to hedge currency risk associated with anticipated Australian dollar expenditures. Our currency hedging program for 2006 involves hedging approximately 70% of our anticipated, non-capital Australian dollar-denominated expenditures. As of June 30, 2006, we had in place forward contracts designated as cash flow hedges with notional amounts outstanding totaling A$929.5 million of which A$216.0 million, A$402.5 million, A$221.0 million and A$90.0 million will expire in 2006, 2007, 2008, and 2009, respectively. Our current expectation for the remaining 2006 non-capital, Australian dollar-denominated cash expenditures is approximately $320 million. A change in the Australian dollar/U.S. dollar exchange rate of US$0.01 (ignoring the effects of hedging) would result in an increase or decrease in our “Operating costs and expenses” of $6.3 million per year.
Interest Rate Risk
     Our objectives in managing exposure to interest rate changes are to limit the impact of interest rate changes on earnings and cash flows and to lower overall borrowing costs. To achieve these objectives, we manage fixed rate debt as a percent of net debt through the use of various hedging instruments. As of June 30, 2006, after taking into consideration the effects of interest rate swaps, we had $840.6 million of fixed-rate borrowings and $540.1 million of variable-rate borrowings outstanding. A one percentage point increase in interest rates would result in an annualized increase to interest expense of $5.4 million on our variable-rate borrowings. With respect to our fixed-rate borrowings, a one percentage point increase in interest rates would result in a $46.7 million decrease in the estimated fair value of these borrowings.

Other Non-trading Activities
     We manage our commodity price risk for our non-trading, long-term coal contract portfolio through the use of long-term coal supply agreements, rather than through the use of derivative instruments. We sold 90% of our sales volume under long-term coal supply agreements during 2005 and 2004. As of June 30, 2006, we had 60 to 70 million tons and 130 to 140 million tons for 2007 and 2008, respectively, of expected production (including steam and metallurgical coal production) available for sale or repricing at market prices. We have an annual metallurgical coal production capacity of 12 to 14 million tons.
     Some of the products used in our mining activities, such as diesel fuel and explosives, are subject to commodity price risk. To manage this risk, we use a combination of forward contracts with our suppliers and financial derivative contracts, primarily swap contracts with financial institutions. In addition, we utilize derivative contracts to hedge our commodity price exposure. As of June 30, 2006, we had derivative contracts outstanding that are designated as cash flow hedges of anticipated purchases of fuel and explosives.
     Notional amounts outstanding under fuel-related contracts, scheduled to expire through 2007, were 27.4 million gallons of heating oil and 12.2 million gallons of crude oil. In addition, we have previously secured fixed price contracts for 5.0 million gallons of fuel. In May 2006, we entered into option contracts to hedge 90% of the then unhedged 2006 volumes. Under these contracts, we had notional amounts outstanding of 22.0 million gallons of crude oil, with scheduled expirations through December 2006, at June 30, 2006. We expect to consume 95 to 100 million gallons of fuel per year. On a per gallon basis, based on this usage, a change in fuel prices of one cent per gallon (ignoring the effects of hedging) would result in an increase or decrease in our operating costs of approximately $1 million per year. Alternatively, a one dollar per barrel change in the price of crude oil would increase or decrease our annual fuel costs (ignoring the effects of hedging) by approximately $2.3 million.
     Notional amounts outstanding under explosives-related swap contracts, scheduled to expire through 2009, were 4.6 million mmbtu of natural gas. We expect to consume 280,000 to 290,000 tons of explosives per year. Through our natural gas hedge contracts, we have fixed prices for approximately 38% of our anticipated explosives requirements for the remainder of 2006. Based on our expected usage, a change in natural gas prices of ten cents per mmbtu (ignoring the effects of hedging) would result in an increase or decrease in our operating costs of approximately $0.5 million per year.
Item 4. Controls and Procedures.
     Our disclosure controls and procedures are designed to, among other things, provide reasonable assurance that material information, both financial and non-financial, and other information required under the securities laws to be disclosed is identified and communicated to senior management on a timely basis. Under the direction of the Chief Executive Officer and Chief Financial Officer, management has evaluated our disclosure controls and procedures as of June 30, 2006 and has concluded that the disclosure controls and procedures were adequate and effective.
     Additionally, during the most recent fiscal quarter, there have been no changes to our internal control over financial reporting that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
PART II – OTHER INFORMATION
Item 1. Legal Proceedings.
     See Note 10 to the unaudited condensed consolidated financial statements included in Part I, Item 1 of this report relating to certain legal proceedings brought against us by Gulf Power Company, the Navajo Nation, the Hopi and Quapaw Tribes, two class action lawsuits brought on behalf of the residents of the towns of Cardin, Quapaw and Picher, Oklahoma and natural resource damage claims asserted by Oklahoma and several other parties, which information is incorporated by reference herein.
