Use of Non-GAAP Financial Information

Our results of operations have undergone significant change due to the impact of litigation accruals, discontinued operations including the gain on the sale of Veritas, stock-based compensation, restructuring, transition and separation matters, charges related to the amortization of intangible assets, and certain other income and expense items that management considers unrelated to the Company’s core operations. The results of operations of Blue Coat have undergone significant change due to the impact of purchase accounting on revenue from prior acquisitions, stock-based compensation, restructuring, transition and integration matters, charges related to the amortization of intangible assets, and certain other income and expense items that management considers unrelated to the Company’s core operations. To help our readers understand our past financial performance and our future results, we supplement the financial results that we provide in accordance with generally accepted accounting principles, or GAAP, with non-GAAP financial measures. The method we use to produce non-GAAP results is not computed according to GAAP and may differ from the methods used by other companies. Non-GAAP financial measures are supplemental, should not be considered a substitute for financial information presented in accordance with GAAP and should be read only in conjunction with our consolidated financial statements prepared in accordance with GAAP. Our management team uses these non-GAAP financial measures in assessing Symantec’s operating results, as well as when planning, forecasting and analyzing future periods. Investors are encouraged to review the reconciliation of our non-GAAP financial measures to the comparable GAAP results, which is attached to our press release and which can be found, along with other financial information, on the investor relations page of our website at: http://www.symantec.com/invest.
