Maybe I can start, and Chris can add a comment too.
What we find, for example, is that there are maximum residue limits on seed and products that are exported from Canada and other markets, which are there to protect animal health and safety in various countries. Canada has a list of its own, so it regulates the chemical residues from crop products that are allowed on seed and other products coming into Canada.
The challenge with it is that every country has a separate list, though we like to think that the science that applies to these products is the same anywhere in the world. It really ought to be, so it's very difficult, because you have different maximum residue levels and, in some cases, some countries don't have residue levels at all. That makes it difficult to know as an exporter whether you can export to that country or whether you're taking a great risk exporting to that country or contracting with importers in those countries.
Our goal is to try to harmonize those regulations internationally based on science.
