My take on it all, is just that. Without definitive terms, you can't and don't know entirely how to calculate the situation.
You can produce postulated answers, but nothing can be definitive.
I would hope that honest accounting would be applied, but what has been honest in concern of these entities thus far?
Pre-payment of a principal before the principal is even drawn for a loan should not only be applied to the principal, but should be drawing fair interest on the positive balance as well. And why not equal interest to that being charged by the treasury?
Lots of possibilities with no definitive answers.
This is the longest Christmas Eve in history!
