Fund A will charge a fee of 45 BP on capital committed and 60 BP on capital invested after the investment period ends. Fund B will charge a fee of 50 BP on capital committed and 55 BP on capital invested after the investment period ends. Both funds expect to have $500,000,000 in capital commitments and project a five-year cycle for startup and acquisitions.
