"In order to be effective, communications and notices to employees must have a consistent message that regularly appears throughout an employee's career. No single notice, no matter how effectively worded or how timely it is provided, will be as effective as a regular series of messages.... An effective participant education plan for lifetime plan participation and effective withdrawal options should have at least three separate parts ... These include effective information contained in the quarterly statement; notices at the time an employee leaves the plan due to a job change, and a pre-retirement education campaign."
