This presentation discusses various matters that are “forward-looking statements” intended to qualify for the safe harbor from liability established by the Private Securities Litigation Reform Act of 1995. Such statements address or may address future plans, objectives, expectations and events or conditions concerning various matters such as capital expenditures, earnings, pension and other costs, competition, litigation, our construction program, our generation plans, our financing plans, potential acquisitions, rate and other regulatory matters, liquidity and capital resources and accounting matters. Forward-looking statements may contain words like “anticipate,” “believe,” “expect,” “project,” “objective” or similar expressions to identify them as forward-looking statements. Factors that could cause actual results to differ materially from those currently anticipated in such statements include: weather, business and economic conditions and other factors which may impact sales volumes and customer growth; the impact of energy efficiency and alternative energy sources, including solar; the costs and other impacts resulting from natural disasters, such as tornados and ice storms; the amount, terms and timing of rate relief we seek and related matters; the results of prudency and similar reviews by regulators of costs we incur, including capital expenditures and fuel and purchased power costs, including any regulatory disallowances that could result from prudency reviews; unauthorized physical or virtual access to our facilities and systems and acts of terrorism, including, but not limited to, cyber-terrorism; legislation and regulation, including environmental regulation (such as NOx, SO2, mercury, ash and CO2) and health care regulation; the periodic revision of our construction and capital expenditure plans and cost and timing estimates costs and activities associated with markets and transmission, including the Southwest Power Pool (SPP) regional transmission organization (RTO) transmission development, and SPP Day-Ahead Market; electric utility restructuring, including deregulation; spending rates, terminal value calculations and other factors integral to the calculations utilized to test the impairment of goodwill, in addition to market and economic conditions which could adversely affect the analysis and ultimately negatively impact earnings; volatility in the credit, equity and other financial markets and the resulting impact on our short term debt costs and our ability to issue debt or equity securities, or otherwise secure funds to meet our capital expenditure, dividend and liquidity needs; the effect of changes in our credit ratings on the availability and cost of funds; the performance of our pension assets and other post employment benefit plan assets and the resulting impact on our related funding commitments; our exposure to the credit risk of our hedging counterparties; the cost and availability of purchased power and fuel, including costs and activities associated with the SPP Day-Ahead Market, and the results of our activities (such as hedging) to reduce the volatility of such costs; interruptions or changes in our coal delivery, gas transportation or storage agreements or arrangements; operation of our electric generation facilities and electric and gas transmission and distribution systems, including the performance of our joint owners; our potential inability to attract and retain an appropriately qualified workforce; changes in accounting requirements; costs and effects of legal and administrative proceedings, settlements, investigations and claims; performance of acquired businesses; and other circumstances affecting anticipated rates, revenues and costs. All such factors are difficult to predict, contain uncertainties that may materially affect actual results, and may be beyond our control. New factors emerge from time to time and it is not possible for management to predict all factors or to assess the impact of each factor on us. Any forward-looking statement speaks only as of the date on which such statement is made, and we do not undertake any obligation to update any forward-looking statement to reflect events or circumstances after the date on which such statement is made. We caution you that any forward-looking statements are not guarantees of future performance and involve known and unknown risk, uncertainties and other factors which may cause our actual results, performance or achievements to differ materially from the facts, results, performance or achievements we have anticipated in such forward-looking statements.
