Use of GAAP and Non-GAAP Financial Information

Our results of operations have undergone significant change due to a series of acquisitions, the impact of stock-based compensation, impairment charges and other corporate events, including the impact on revenue of the ongoing investigation into Symantec’s compliance with certain provisions of its 2007 GSA contract. 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. Our non-GAAP results are not meant to be considered in isolation or as a substitute for comparable GAAP measures and should be read only in conjunction with our consolidated financial statements prepared in accordance with GAAP.

Our management regularly uses our supplemental non-GAAP financial measures internally to understand, manage and evaluate our business and make operating decisions. These non-GAAP measures are among the primary factors management uses in planning for and forecasting future periods. Investors are encouraged to review the reconciliation of our non-GAAP financial measures to the comparable GAAP results, which can be found, along with other financial information, on the investor relations’ page of our website at www.symantec.com/invest.
