The decision as to whether or not to rollover a retirement plan account to an IRA should be based on more factors than just the associated mutual fund management expenses. On its website, the Dept. of Labor provides guidance to retirement plan participants, i.e. employees, on how to evaluate the fees and expenses associated with their plan: "... don’t consider fees in a vacuum. They are only one part of the bigger picture including investment risks and returns and the extent and quality of services provided. Keep in mind the importance of diversifying your investments."
