Okay.
Well, when it comes to supply chain security, we are having ongoing discussions with the U.S., because I think both of us are concerned about the kinds of disruptions we saw, particularly in the earlier stages of the pandemic, and we want to make sure that doesn't happen again.
We're having discussions about how we can make sure that our supply chains are going to be more secure, how we can ensure that our own integrated markets can perform a lot of those functions, and how maybe we can expand that even further so that we can have full confidence in each other in terms of having secure supply chains. It's really about looking at where you're getting your supply from—and we are certainly a secure supplier—and looking at countries where you may not have that same level of comfort and seeing whether there are other options. Those are the kinds of issues that we're looking at now.
