I'll maybe build on an earlier discussion. I'm not sure what the chances are that the United States might withdraw from the government procurement agreement. That is ultimately a decision that will have to be taken by the U.S., presumably in consultation with its key stakeholders.
Certainly that is something we will have to take very seriously should that come to fruition or should we perceive that to be a real risk. We will endeavour to engage with U.S. interlocutors at every opportunity to try to clarify their specific position. Ultimately, I'm not sure how that will play out. That is something we would be studying very carefully.
