For clarity, the individual must be fully vested upon attainment of normal retirement age, but it is possible for the plan to define normal retirement age as the later of attainment of an age not later than age 65 (i.e., it could be younger) or the passage of up to 5 years from the employee's commencement of participation in the plan [1.411(a)(7)(b)]. Note that this is NOT an accumulation of either eligibility or vesting years of service, but rather is the passage of time from the commencement of participation.

@Coleboy1, check the plan's definition of normal retirement age to see if there is a time component.
