Yes, we have. When you move from the bilateral to the multilateral, it's always more difficult, but at the end of the day, if we want to confront global taxpayers, whether individuals or large multinational corporations, the ideal way of doing it is by multilateral conventions, so we're supplementing these bilateral agreements with multilateral conventions. These multilateral conventions initially are between the OECD countries, but we want to take these out; we want to have other G-20 countries that are not OECD countries come in and we want developing countries to join us as well.
It's not going to be easy; it does take time, and there are issues of confidentiality. Canada, for instance, will not give information to a country unless they know that the country can protect the confidentiality of the information. However, I'm confident that the future very much lies in extending this multilateral agreement to as many countries as possible.
