Sure.
We had a conversation with finance officials yesterday about the composition of that difference. What we were told is that about $4 billion of that difference is essentially from the fact that departments spent a lot less than what the government expected or projected at the time of the budget in March. We have not really figured out exactly what the source of that is; we are still looking at it. But it looks as though a lot of it is due to accrual adjustment that is done at the end of the fiscal year by the departments for their various expenses. That would explain some of that big difference. The rest of that $7 billion is mostly corporate tax revenues that came out larger.
