I think the idea of simply a fee for time (consulting) or a fee for assets under management may not ever be the right answer. If the problem has multiple dimensions and multiple sources of conflict then the solution probably has to be multi-pronged. I believe we need to have three compenents to the fee discussion:
1 - Fees for safekeeping/oversight (10bp)
2 - Fees for communication/insight ($50-200 per hour) typically 5-10 hours/yr
3 - Fees for value add (10% of return greater than benchmark, with highwater mark)

Vast majority of assets in $500k to $2.5 million and 60% Equity(SP500)/40% bonds (Barclays Agg). Level of person speaking to client could vary based on complexity.

For a $1 million with 4 meetings, $1000 asset based fee plus a $1000 time based fee and with value add of 1%, yields another $1000 for total of 30bp. These numbers may need to be tailored to accomodate a each advisory practice.
