With respect to most favoured nation clauses, I wouldn't be able to give an exact number, but they are important clauses that have actually been the subject of a number of trade disputes. I can't speak to how many of them actually have gone through the entirety of the process, but the most favoured nation clause and the assurance that we're actually providing equal treatment to all are important considerations.
I'd also just note that, in the vast majority of cases we get, the lead investor and the origin country of the lead investor are not usually the subject of the concern; it's usually a minority relationship that actually exists within the investor company. Therefore, by exempting Five Eyes from national security reviews, you wouldn't want to, by some sort of proxy, actually suggest that the minority relationships of those countries' investors are somehow not subject to review, because actually a huge chunk of the things we review involve an allied country investor.
