2 Forward Looking Statement This presentation contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, Section 21E of the Securities Exchange Act of 1934 and the Private Securities Litigation Reform Act of 1995. Forward-looking statements may be identified by the context of the statement and generally arise when the Company is discussing its beliefs, estimates or expectations. These statements are not historical facts or guarantees of future performance but instead represent only the Company’s beliefs at the time the statements were made regarding future events which are subject to significant risks, uncertainties and other factors many of which are outside the Company’s control. Actual results and outcomes may differ materially from what is expressed or forecast in such forward-looking statements. The principal risks and uncertainties that may affect the Company’s actual performance include the following: the cyclical and seasonal nature of the Company’s business; public infrastructure expenditures; adverse weather conditions; restrictive covenants contained in our debt agreements; availability of raw materials; changes in energy costs including, without limitation, increases in natural gas and oil; changes in the cost and availability of transportation; unexpected operational difficulties, equipment failures and catastrophic events; inability to timely execute announced capacity expansions; governmental regulation and changes in governmental and public policy (including climate change regulation); changes in economic conditions specific to any one or more of the Company’s markets; competition; announced increases in capacity in the gypsum wallboard and cement industries; changes in demand for residential housing construction or commercial construction; environmental liabilities; general economic conditions (including the possibility of the deepening of the current economic recession); and interest rates. For example, increases in interest rates, decreases in demand for construction materials or increases in the cost of energy (including natural gas and oil) could affect the revenues and operating earnings of our operations. In addition, changes in national and regional economic conditions and levels of infrastructure and construction spending could also adversely affect the Company’s results of operations. These and other factors are described in the Annual Report on Form 10-K for the Company for the fiscal year ended March 31, 2008 and in its quarterly report on Form 10-Q for the fiscal quarter ended December 31, 2008. These reports are filed with the Securities and Exchange Commission and may be obtained free of charge through the website maintained by the SEC at www.sec.gov. All forward-looking statements made in this presentation are made as of the date hereof, and the risk that actual results will differ materially from expectations expressed in this presentation will increase with the passage of time. The Company undertakes no duty to update any forward-looking statement to reflect future events or changes in the Company’s expectations. |
