I think that's an extremely important concept. Sole-sourcing is probably one of the key factors associated with the Sandoz shortage, whether it was the provinces themselves or the group purchasing among all of the hospital groups across the country that led to it.
I will refer to one of the countries that we put in our report, New Zealand. It has a central agency in place for the management and purchasing of pharmaceuticals. They have some very strict penalties in place for companies that do not provide a critical product, or that run out of it.
I certainly believe that some backup plans need to be in place. It could be by identifying the critical agents that we really do need to have additional information or additional backups for, and/or some system whereby we can look at a more competitive market or for another source of that product.
