Unfortunately, I'm not directly involved in that aspect of the work, so I don't know the extent to which that kind of analysis might be going on. As I did mention earlier, there's a continual examination going on about what we should be considering as essential workers and essential travel back and forth across the border, because we do have restrictions on the most significant commercial border in the world. That's a complex process that is continually being re-examined.
I apologize that I don't have any more specific details I can offer you.
