I support what my colleague has just said.
In addition, we actually have a mix of investigators. We usually use external investigators, but we do, in some regions, use some internal investigators depending on the nature of the issue.
What we find currently is that it's difficult to find a good, significant pool of investigators. There are some out there, but they're very busy, and it's difficult to find a competent investigator, certainly for part XX currently. That's certainly something I think we need to turn our minds.
