Although CSW and each of its subsidiaries believe that, in making any such statements, its 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.; 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; 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 or acquire domestic and international power projects and utility assets. In the non-utility area, the aforementioned factors would also apply, and, in addition, would include: 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.
