I suppose I should try to respond to that as well. Thank you very much for the question.
Commercial confidentiality concerns do indeed have a huge impact on the useful exchange of information internationally among regulatory agencies. We try to overcome that problem by entering into confidential information exchange agreements with other jurisdictions.
For example, when REACH is finally adopted it will contain a clause that mirrors a clause in CEPA that allows for the confidential exchange of information. We also have a useful arrangement with Australia already in place. There are some difficulties with the United States because of the way the confidentiality arrangements are written into TOSC. There are some impediments there, but we've tried to overcome them through something called the four corners arrangement. It includes the chemical companies themselves waiving confidentiality requirements so they can share data with both agencies at the same time.
So we're constantly trying to do that, but there are some legal impediments there.
