We didn't look at trade missions mission by mission. We looked at the 17 visits as an ensemble, estimating the average effect of those missions. And the average effect was zero. If you start going country by country, the trade is just so volatile, it's just bouncing around, and it's very hard to see what's going on at all. We did some graphing of it. Trade bounces around a lot, so you have to take all the missions together and average them out to see what's happening. And the average is basically zero.
With regard to what you said about the memorandums of understanding, etc., what we've heard from talking to people is that they would take some deals that were already happening, and then they would hold off on announcing them for a while so that they could announce them at the mission. And they would take other things that were sort of wishful thinking, hoping they might someday come together, and add those. So in other words you take the future that may not happen, and you take the past that's already happened, you lump them together and announce this big thing, but that's not really a change that was brought about by the mission.
