So now we're going to look at notional pooling together. So I bring up the four accounts. We've got the bounces of plus 10, plus 5, minus 15, and plus 8. Now, if I put those accounts into an arrangement where I treat them as one account for interest purposes, that will mean that with a bounce of plus 10, plus 5, minus 15 and plus 8. For interest purposes, I would look at an overall position of plus 8 as a corporate. What I'm interested in here is that my account balances haven't moved yet. For interest purposes, I benefit from a plus 8 position.
