The challenges are first with the countries unwilling to move towards automatic exchange of information because some stand ready, and nowadays all stand ready to give tax information exchange agreements or tax convention. The global forum is taking care of that to make sure that if a country refuses to do so it's identified and the recommendation is made and this is brought to the knowledge of the G-20. But automatic exchange of information is not the standard. It's not the OECD standard and therefore it's under voluntary compliance.
The second aspect of automatic exchange of information is to make sure that it works properly. Here again the OECD is doing quite a lot of work to make sure that with the information you receive you can make the proper analysis of it and that it matches, because you can have two different languages and you can have two different IT systems supporting it. This is the nitty-gritty type of the work we are performing currently.
