The day-to-day operations of isotope supply still continue from NRU. So there is no immediate impact on our company related to the supply of isotopes today. If the MAPLE project is not completed, that is a long-term issue for us and there will an impact on our company. In terms of how we respond to that, we haven't really had a chance to think about that; it is a longer-term issue. In the short term we still continue to receive isotopes from a very reliable NRU reactor.
