A bit more info on this -
Yep - I held the money in the account for 17 years after I left but was getting good returns on a yearly basis. However, the company is terminating the plan effective the end of this month so I'm reviewing my options of basically either rolling it over to my current employer or, if I take no action, the plan is automatically rolled over to another fund company to manage it. Based on my cursory review of the fund company they are rolling over to, I'd rather roll it into my current 401K plan.
