Thank you.
I would say that we're looking at it from both perspectives, actually. First of all, we're starting with the principles of what are we trying to achieve, which is effective entry into each other's market without these kinds of barriers, so we're designing a system that includes some of the various elements that we've talked about: bridging the gaps between existing regulations where they exist; moving forward on regulatory cooperation; finding approaches to mutual acceptance of regulations in some cases; recognizing each other's conformity assessment bodies, which is another way of cutting through a lot of the extra complications. But at the same time, we've both identified lists of specific barriers that we're trying to address concurrently with the negotiations. Those include a number of sanitary and phytosanitary barriers that exist now, and they also include a number of technical barriers to trade that exist now. So we've got a parallel process ongoing to try to deal with those issues, while in the negotiations themselves we're also trying to develop a structure that will put us in a position where we don't have to face these in the same way in the future.
