GEOList Summary: Grant Management Fees

For any of my peers that are managing grant programs for other entities in the community, could you share what your fee structure looks like? Do you asses fees by charging a flat percent on the amount of the asset in the fund, per grant cycle, or per application reviewed? I am working on a partnership whereas we would manage a fund, a couple of grant cycles a year, a selections committee, and the due diligence of any funds granted.
