Thank you. I'll actually continue from the answer I was trying to provide.
When we know that like-minded countries are following those rules on zoning and have good veterinary oversight and we have confidence, we will draw up those agreements with them. We are doing one with the U.S. and one with Europe, and are working with Japan to get one in place. Then we'll look at other countries as we continue to get that confidence in place.
With the U.S., we're very close to actually having that. Under our regulatory co-operation with the U.S., we have a zoning agreement in place that we have been practising for avian influenza management. We just wanted to make sure that we had the right sort of case and conditions in place as we were finalizing this with the U.S. We have done that, and both the U.S. and Canada will practise it if the disease happens in either country.
