Ann: Subscription Agreements Funding Update, page-34

Safe answer

.. here's one interpretation that supports my uneducated personal opinion that the entire $25 million is being sent all at once:

"Completion

Spot transactions (discussed above in 1.), if conducted between a bank and a customer or between banks must be conducted by transferring the principal amount in full. However, the other types of transaction discussed in 2. and 3. above can be conducted by either netting (only for rollover, early termination, and termination/unwinding transactions) ortransferring the principal amount in full."
