FORWARD LOOKING STATEMENT: This press release contains forward-looking
statements, including forecasts of future revenue and earnings per share,

involve known and unknown risks, uncertainties and other factors that may cause
our actual results, levels of activity, performance or achievements to differ
materially from results expressed or implied by this press release. Such risk
factors include, among others: the sustainability of recent growth rates,
particularly in consumer products; the anticipation of the growth of certain
market segments, particularly enterprise security; the positioning of Symantec's
products in those segments; the competitive environment in the software

USE OF NON-GAAP FINANCIAL INFORMATION: In addition to reporting financial
results in accordance with generally accepted accounting principles, or GAAP,
Symantec reports non-GAAP financial results. Non-GAAP net income and earnings
per share exclude acquisition related charges, such as amortization of other
intangibles and in-process research and development, and certain other
identified charges, such as restructuring and patent settlement, as well as the
tax effect of these items. Symantec's management believes these non-GAAP
measures are useful to investors because they provide supplemental information
that facilitates comparisons to prior periods. Management uses these non-GAAP
measures to evaluate its financial results, develop budgets and manage
expenditures. The method Symantec uses to produce non-GAAP results is not
computed according to GAAP, is likely to differ from the methods used by other
companies and should not be regarded as a replacement for corresponding GAAP
measures. Investors are encouraged to review the reconciliation of these
non-GAAP financial measures to the comparable GAAP results, which is attached to
this release and can also be found on the investor relations Web site at
www.symantec.com/invest/center.html.
