Covidien and Lantheus have been sharing when they can, but it does add to the fragility. So I think we're dealing with that.
The second way is supply of molybdenum to the individual generator manufacturer and the approval of the molybdenum supply from a regulatory point of view.
There has already been approval by Health Canada for molybdenum supplied by Australia. They're not yet in a position to supply as much as is needed. The hope is that they will be able to expand supply going forward.
Secondly, there are other manufacturers of generators around the world, and one of those manufacturers is currently having their generators tested in Canada at the moment. We're looking for quality, we're looking for quality assurance, we're looking for reliability. If it looks as if they meet those criteria, then we can look at a regulatory approval for another generator supply.
So the answer to your question is the supply is obviously dependent on the beginning of the supply chain, which is the reactor's supply of molybdenum. If that is disrupted at the beginning, then no matter how carefully anybody plans, the rest of the world is going to be down.
