<prompt> Human: I left a job in 2006 without being fully vested in my 401k. Fidelity still shows the balance as including the employer matched amount that they should have retracted when I left. Ive left the 401k alone for years thinking that Im making dividends off that artificially increased balance.Should I continue to leave it alone? When will my former company reclaim the amount that was not vested from my account? Is there any kind of time limit for this kind of operation?  <response>: I think theyll figure out how much you have vested when you try to roll over the balance into a new account which I recommend doing anyway.
