International comparisons are always very difficult to do, to ensure that we're comparing one thing with another, because of the variation in commodities, regional conditions, etc. We have some comparators, but we tend to not really spend much time trying to compare one commodity with another, between countries.
We're certainly, on the other hand, very attentive to changes in other countries to trade rules, subsidies and the like. We watch those very attentively.
We could come in and talk specifically about international comparators, but we don't really have anything to share with you here today.
