Just to follow up on that, there have been a number of independent studies done over the years that have looked at single-desk selling versus the competition, and comparing prices in those two environments. The first one was by Kraft, Tyrchniewicz, and Furtan, who are university professors from each of the western or prairie universities. That study was done in the early nineties. Their numbers range from $10 to more than $20, depending on the circumstances, and so forth.
Richard Gray did a study more recently, looking at the wheat side, and had a lot of broad consultations. Richard Gray is a University of Saskatchewan professor. His numbers came out between $10 and $15 a tonne for the benefit of the single desk over an open-market scenario.
Schmitz, from the University of California, has done a couple of studies on the barley side. Again, those numbers vary anywhere from $10 to $25, again depending on the market dynamics and what they're looking at.
Those are three public, independent studies that have been done.
