The answer to your question is that both exist. On an international level, the OECD high-level working group--I think Canada is represented by Serge Dupont on that panel--met in December and meets again in June. It brings together representatives from nation states around the world to discuss and focus on these issues.
In last December's meeting it established a number of task forces. In fact, we're working on one on iodine-131, and there are other task forces. At the same time, there are very robust efforts going on. I would highly recommend some connecting with the European Union. They recently did a massive report on everything you ever wanted to know about medical isotopes. They put out this preliminary report in October. It's a great resource. They're having another meeting of nation-states in May in Luxembourg.
On the piece with the companies, we see that diversity of supply and interchangeability--that's an excellent point--are important to us as a business. We're driving that, so there's an alignment of interest there. But I do think that more frequent international communication will be a good thing here.
