In this case, it’s not really a waiver but a deferral of fees and, as stated in the last sentence of the footnote, applying these additional deferred fees on the fund could well have the affect of keeping the interest paid to investors down for a lengthy period.
Stable value funds are soap box racers that now face constraints that will limit their top speed. Our money market funds will soon have the performance attributes of a pinewood derby car dressed up as a turtle, with a smallish piano on its back. I haven’t read the official pinewood derby rule book as of yet, but this does not sound like a winning configuration.
Stable value and money market funds have more differences than similarities. These differences do not necessarily make one better than the other but it is fair to say that the average stable value fund should credit a higher rate of interest than the average money market fund over the long haul.
