Although CSW and certain of its subsidiaries believe that, in making any such statements, their expectations are based on reasonable assumptions, any such statements may be influenced by factors that could cause actual outcomes and results to be materially different from those projected. Important factors that could cause actual results to differ materially from those in the forward-looking statements include, but are not limited to: the impact of general economic changes in the U.S. and in countries in which CSW either currently has made or in the future may make investments; the impact of deregulation on the U.S. electric utility business; increased competition and electric utility industry restructuring in the U.S.; the impact of the proposed merger with AEP including any regulatory conditions imposed on the merger, the inability to consummate the merger with AEP, or other merger and acquisition activity including SWEPCO's proposed acquisition of Cajun Electric Power Cooperative, Inc.; federal and state regulatory developments and changes in law which may have a substantial adverse impact on the value of CSW System assets; timing and adequacy of rate relief; adverse changes in electric load and customer growth; climatic changes or unexpected changes in weather patterns; changing fuel prices, generating plant and distribution facility performance; decommissioning costs associated with nuclear generating facilities; costs associated with any year 2000 failure either within the CSW System or supplier failures that adversely affect the CSW System; uncertainties in foreign operations and foreign laws affecting CSW's investments in those countries; the effects of retail competition in the natural gas and electricity distribution and supply businesses in the United Kingdom; and the timing and success of efforts to develop domestic and international power projects. In the non-utility area, the previously mentioned factors would apply and also include, but are not limited to: the ability to compete effectively in new areas, including telecommunications, power marketing and brokering, and other energy related services, as well as evolving federal and state regulatory legislation and policies that may adversely affect those industries generally or the CSW System's business in areas in which it operates.
