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 acquired in-process
research and development and amortization of goodwill and other intangibles, and
certain other charges, such as restructurings and site closures, 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 be found on the investor relations Web site at
www.symantec.com/invest/center.html.

* For the three and twelve months ended March 31, 2003, diluted net income per
share is calculated using the if-converted method. Under this method, the
numerator excludes the interest expense from the 3% convertible subordinated
debentures, net of income tax, of $3.6M and $14.4M for the three and twelve
months ended March 31, 2003, respectively, and the denominator includes shares
issuable from the assumed conversion of the 3% convertible subordinated
debentures. For the three and twelve months ended March 31, 2002, diluted net
income (loss) per share excludes the assumed conversion of the 3% convertible
subordinated debentures, as their effect would be anti-dilutive.

* For the three and twelve months ended March 31, 2003 and 2002, diluted net
income per share is calculated using the if-converted method. Under this method,
the numerator excludes the interest expense from the 3% convertible subordinated
debentures, net of income tax, of $3.6M and $14.4M for the three and twelve
months ended March 31, 2003, respectively, and $3.6M and $6.2M for the three and
twelve months ended March 31, 2002, respectively, and the denominator includes
shares issuable from the assumed conversion of the 3% convertible subordinated
debentures.
