The earliest possible vesting is 25% annually over four years, however, depending on the timing of the achievement of specified performance goals, the grantee has up to seven years to completely vest in the award. Part or all of the award will not be vested if the employment ends prior to complete vesting or if the performance goal is not achieved as of the last vesting opportunity.
