25 This presentation contains forward-looking statements, including statements regarding our current expectations for future financial performance and cash flows, capital expenditures, our current plans or objectives for future operations, future hydroelectric generation projections and other factors, which may affect the company in the future. Such statements are subject to a variety of risks, uncertainties and other factors, most of which are beyond our control and many of which could have significant impact on our operations, results of operations, financial condition or cash flows and could cause actual results to differ materially from those anticipated in such statements. The following are among the important factors that could cause actual results to differ materially from the forward-looking statements: weather conditions, including the effect of precipitation and temperatures on the availability of hydroelectric resources and the effect of temperatures on customer demand; changes in wholesale energy prices that can affect, among other things, cash needed to purchase electricity, natural gas for our retail customers and natural gas fuel for electric generation, and the value of surplus energy sold, as well as the market value of derivative assets and liabilities; volatility and illiquidity in wholesale energy markets, including the availability and prices of purchased energy and demand for energy sales; the effect of state and federal regulatory decisions affecting our ability to recover costs and/or earn a reasonable return including, but not limited to, the disallowance of costs that we have deferred; the potential effects of any legislation or administrative rulemaking, including the possible adoption of national or state laws requiring resources to meet certain standards and placing restrictions on greenhouse gas emissions to mitigate concerns over global warming; the outcome of pending regulatory and legal proceedings arising out of the “western energy crisis” of 2000 and 2001, and including possible retroactive price caps and resulting refunds; the outcome of legal proceedings and other contingencies; changes in, and compliance with, environmental and endangered species laws, regulations, decisions and policies, including present and potential environmental remediation costs; wholesale and retail competition including, but not limited to, electric retail wheeling and transmission costs; the ability to relicense and maintain licenses for our hydroelectric generating facilities at cost-effective levels with reasonable terms and conditions; unplanned outages at any of our generating facilities or the inability of facilities to operate as intended; unanticipated delays or changes in construction costs, as well as our ability to obtain required operating permits for present or prospective facilities; natural disasters that can disrupt energy production or delivery, as well as the availability and costs of materials and supplies and support services; blackouts or disruptions of interconnected transmission systems; the potential for future terrorist attacks or other malicious acts, particularly with respect to our utility assets; changes in the long-term climate of the Pacific Northwest, which can affect, among other things, customer demand patterns and the volume and timing of streamflows to our hydroelectric resources; changes in future economic conditions in our service territory and the United States in general, including inflation or deflation; changes in industrial, commercial and residential growth and demographic patterns in our service territory; the loss of significant customers and/or suppliers; default or nonperformance on the part of any parties from which we purchase and/or sell capacity or energy; deterioration in the creditworthiness of our customers and counterparties; our ability to obtain financing through the issuance of debt and/or equity securities, which can be affected by various factors including our credit ratings, interest rates and other capital market conditions; the effect of any change in our credit ratings; changes in actuarial assumptions, the interest rate environment and the actual return on plan assets for our pension plan, which can affect future funding obligations, costs and pension plan liabilities; increasing health care costs and the resulting effect on health insurance provided to our employees and retirees; increasing costs of insurance, changes in coverage terms and our ability to obtain insurance; employee issues, including changes in collective bargaining unit agreements, strikes, work stoppages or the loss of key executives, as well as our ability to recruit and retain employees; the potential effects of negative publicity regarding business practices, whether true or not, which could result in, among other things, costly litigation and a decline in our common stock price; changes in technologies, possibly making some of the current technology obsolete; changes in tax rates and/or policies; and changes in our strategic business plans, which may be affected by any or all of the foregoing, including the entry into new businesses and/or the exit from existing businesses. For a further discussion of these factors and other important factors, please refer to the company’s Annual Report on Form 10-K for the year ended Dec. 31, 2007 and the company’s 10-Q for the quarter ended March 31, 2008.
