We have a minimum hurdle and that's tied to our long-term remuneration scheme, so we don't want to flirt with it too much. If people don't get paid, they won't stay.
The minimum that we want to deliver over a 10-year horizon is 3.5%, but we definitely want to be above that, so probably in the 5% to 7% range. With these things, it's really hard, and I would counsel this, to be precise.
We looked at our historic returns, deal by deal, and of course the distribution is all over the map. It's as much driven by your failure rate, so how many actually lose all their money, as it is by how you're structuring each deal and what you're looking for from each deal.
