If you look at all the borrowings you will note that the " total cost" is about 1.5 to 2.5 times the "amount borrowed," except for the PERS and STRS loans. For the teachers the factor is over 3. For the PERS loan it is almost a factor of 7.
What this means is that something is very strange about these loans. The loans are either for an exceptionally long period of time (like 30 or 40 years) or the loans have no principal or interest payments for the first few years. There is something about these loans that makes them more expensive in terms of interest cost, based on total payment.
That should be a red flag that says politics is involved.
Anybody have a financial calculator to play with those PERS numbers? We know the present value and future value, so it would be simple to assume some things and come up with some hypothetical numbers.
