Your comment in post #2 seems to refer to the figures in the ‘Discretionary’ column. The sum of the figures in the ‘Mandatory’ column is much greater than the interest payment figure.
So the question would be, why not look at the total sum of both columns when making that comparison?
I don’t know. When I first looked at it, I was thinking it was just 10 years versus 1 year. Looking closely at it, that clearly can’t be what it is.
I’m going to have to read more about it. Wish I had a better answer than that, but that’s where I’m at right now.
