Our forward-looking statements are based on numerous assumptions that the company believes are reasonable, but they are open to a wide range of uncertainties and business risks that may cause actual results to differ materially from expectations as of April 15, 2009. These factors are difficult to accurately predict and may be beyond the company's control. The company does not undertake to update its forward-looking statements. Factors that could affect the company's results include, but are not limited to: the duration and severity of the global economic downturn and disruptions in the financial markets; ability to renew sales contracts; reductions and/or deferrals of purchases by major customers; credit and performance risks associated with customers, suppliers, trading and banks and other financial counterparties; transportation availability, performance and costs, including availability, timing of delivery and costs of key supplies, capital equipment or commodities such as diesel fuel, steel, explosives and tires; geologic, equipment and operational risks inherent to mining; impact of weather on demand, production and transportation; replacement of coal reserves; price volatility and demand, particularly in higher-margin products and in our trading and brokerage businesses; performance of contractors, third-party coal suppliers or major suppliers of mining equipment or supplies; negotiation of labor contracts, employee relations and workforce availability; availability and costs of credit, surety bonds, letters of credit, and insurance; changes in postretirement benefit and pension obligations and funding requirements; availability and access to capital markets on reasonable terms to fund growth and acquisitions; legislative and regulatory developments, including mercury and carbon dioxide-related limitations; the outcome of pending or future litigation; coal and power market conditions; availability and costs of competing energy resources; risks associated with our Btu Conversion or generation development initiatives; global currency exchange and interest rate fluctuation; wars and acts of terrorism or sabotage; political risks, including expropriation; and other risks detailed in the company's reports filed with the Securities and Exchange Commission.
