We have quite a few 401(k) plans with profit sharing accounts that have 3/20 vesting and are under the impression that the 2007 safe harbor notices can be given to the participants without the plans being amended to 2/20 vesting as prescribed by PPA. Just wanted to be sure - is this correct, and when would the plans actually need this amendment? Or would it just be part of the inevitable PPA restatement that will happen years from now as long as the plan operationally uses the new schedule? All help is appreciated.
