I personally don't have concerns that there's going to be a holdup at the border. I think that when anything new comes in there's potentially some uncertainty, and it takes some time to kind of get your arms around that. There may be some potential issue, but I personally don't see that—and our team doesn't—as a major risk.
I think some of the discussion around implementation timing is really to just get better clarity on exactly how some of these rules are going to work. There's a bit of a question about the detail around it, which is why there's been some discussion around delaying the implementation, just to make sure that everybody has very good clarity on how the calculations work and that type of thing.
