It's not something that's usual, especially when the amounts are fairly specific and vary from year to year. You mentioned the net amount over five years, I believe. Again, the amounts are positive and fairly accurate in some years, but negative in other years. So the absolute value of these amounts hovers around $12 billion, over a five-year period.
This raises a lot of questions, but doesn't give us any answers. We have asked officials these questions and they have not answered us, as they are not authorized to provide us with those details. This is highly unusual.
