Symantec has adopted a policy that executive officers and members of the Board hold an equity stake in the Company. The policy requires each executive officer to hold a minimum number of shares of Symantec common stock. Newly appointed executive officers are not required to immediately establish their position but are expected to make regular progress to achieve it. The Nominating and Governance Committee reviews the minimum number of shares held by the executive officers and directors from time to time. The purpose of the policy is to more directly align the interests of our executive officers and directors with our stockholders. See “Stock Ownership Requirements” under the Compensation Discussion & Analysis section for a description of the stock ownership requirements applicable to our executive officers.
