Ownership generally increases in stages. Each stage can provide a greater vested percentage until the participant becomes fully vested.
Your vested balance and unvested employer contributions can be treated differently when you leave an employer.
Your vested employee contributions generally remain yours, subject to the rules governing the account and distribution.
Employer contributions that are vested generally remain part of your account balance, subject to applicable plan rules.
Unvested employer contributions may be forfeited when you leave the plan, depending on the plan's rules and applicable requirements.
A matching contribution can increase your 401(k) balance, but the plan may specify when those employer contributions become fully vested.
