If you enroll when you first start with the Federal Reserve, then you are 20 percent vested in all Employer Matching contributions and investment earnings on that money after one year of service with the Federal Reserve, and you are credited with a year of service at your employment anniversary date.
If you retire on or after age 65, become totally and permanently disabled, die, or the Plan terminates, then you are 100 percent vested, and there is no service requirement.
If you do not elect to participate when you first start working with the Federal Reserve, then you will receive vesting service credit for years of service with the Federal Reserve before you become a participant, and you can enroll at any time.
