Come September, there are new regs for reporting fees for 401k retirement plans. This should be interesting, as this recent study (based on a model) estimates 401k fees, including hidden fees, at about 30% of total return: http://www.demos.org/publication/retire ... osts-401ks
This may be overstated, but it will be worth looking at, even if the fee information is buried on pg. 37, footnote 22
