Is the authorization of the excess funds management facility a good ideas?

After going through the GFC, I closed a similar excess fund management facility with my broker. I feel uncomfortable because money market funds are not exactly risk free and the fund manager can invest in all kinds of commercial papers, and not only that we could be taking all sorts of counter party risks that we are not aware of. All these for that 0.X% additional returns which is not even guaranteed.
