How complex is the relationship between fund families and brokers /
distributors from an operational perspective?  How much does it cost
to
manage the transactions between the two (e.g., in terms of money
transfer, settlement, etc.)  Is this cost already considered in the
distribution fee? Or is the cost split 50/50 between distributor and
manufacturer?  How is this different for fund supermarkets (e.g.,
Schwab).  I'd really like to know about the necessary operational
costs to "manage" fund transactions.
