Investors can usually leave their existing 401k account in place after going from one job to another. You can
start a new 401k account with your new employer.
Advantages with this option:
You do not have to go through the process of rollover (requires many steps).
You do not have to withdraw your money, which would result in heavy penalties.
Disadvantages with this option:
You do not have as much control over your funds.
You may be subjected to fees.
You must rely on your former employer to manage your 401k account.
Generally, loans previously taken are required to be repaid upon termination.
