Certainly there are some things mitigating in our favour. Frankly, we participate in the increase in market prices for isotopes that has occurred. The shortage and the stress on the supply chain increased the prices. We derived a benefit from that in terms of the net back, or our share of those revenues. At the same time, we have to be mindful that we are continuing to spend substantial amounts of money on the isotope supply reliability program and that spending will exceed the revenues we bring in.
I don't believe there's any basis on which you can make the claim that isotope production is a commercially viable business or an economic or compensatory business for us. We do it because of a government policy direction and social policy objectives, and we're pleased to do it.
