Has anyone seen a fee study on retirement plan administration?

ASPA did a survey of financial results for plan adminstration firms in 1997 which has some mention of fees--just some averages, not enough breakdown by plan type, size, etc. to make it really useful to me, but you might find it of some use.

I don't know if the survey is still available from ASPA, but it is called "1997 Financial Survey Results" and was offered for sale to ASPA members in late 1997 or early 1998 for about $150 (less for those who actually participated in the survey). Contact ASPA at 703 516-9300 or check their website--aspa.org.
