It is an ongoing analysis that we do as to when is the right time to take that further step. Part of the issue is that there are some ongoing technical discussions happening, and if we feel there is some forward movement in those discussions, then that could be a quicker way to resolve the problem than going through a lengthy WTO dispute settlement panel process.
At some point, we will have to make the judgment as to whether those technical discussions are productive enough that we continue down that track, or whether we feel that it is now time to move on to a WTO panel request. It's an ongoing assessment and we'll continue to assess that as time goes on, but we also want to make sure that through these technical discussions we're collecting all of the evidence we need to put forward a very strong case at the WTO.
