Forward-looking statements: The matters discussed here and elsewhere in this
investor presentation are "forward-looking statements." The Private Securities
Litigation Reform Act of 1995 has established that these statements qualify for
safe harbors from liability. Forward-looking statements may include words like
we "believe," "anticipate," "expect" or words of similar meaning.
Forward-looking statements describe our future plans, objectives, expectations
or goals. Such statements address future events and conditions concerning
capital expenditures, earnings, liquidity and capital resources, litigation,
rate and other regulatory matters, possible corporate restructurings, mergers,
acquisitions, dispositions, including the proposed separation of Westar
Industries, Inc., from our electric utility businesses and the consummation of
the acquisition of our electric operations by Public Service Company of New
Mexico, compliance with debt covenants, changes in accounting requirements and
other accounting matters, interest and dividends, Protection One's financial
condition and its impact on our consolidated results, environmental matters,
changing weather, nuclear operations, ability to enter new markets successfully
and capitalize on growth opportunities in non-regulated businesses, events in
foreign markets in which investments have been made, and the overall economy of
our service area. What happens in each case could vary materially from what we
expect because of such things as electric utility deregulation, ongoing
municipal, state and federal activities, such as the Wichita municipalization
efforts; future economic conditions; legislative and regulatory developments;
competitive markets; and other circumstances affecting anticipated operations,
sales and costs. Any forward-looking statement speaks only as of the date such
statement was 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 was made.
