Yeah. So, Brian, it's Joe. So, post list 3, that late September list, what I'll call unmitigated exposure is $75 million. So, it bumped up significantly from us -- for us on list 3. List 3 captured couple of -- mostly in the connection systems business, a couple of products that we manufacture globally in one location or the other and ship, and that was a decision we made, that was a capital deployment decision at the time, we could build global capacity in one place and build for the world that we did. So, mitigation activity, it's really come in a couple of ways. One, it's moving production, and that obviously is going to take a little bit of time. We need to do that with help from the customers as, obviously, validation and such that needs to take place. Pushing the costs, either up or down in the supply chain, to customers or to suppliers is another lever we have. And then we are spending some time, particularly with the Chinese government on, at least, the products that are made there globally, if there's some way to offset those tariff costs, working with them as a means of keeping the jobs in China. So we're, I would say, at this point, turning over all rocks. We'll clearly mitigate some of that exposure in '19. At this point, just given where we are in the planning process and work under mitigation, I can't give you the exact number that will mitigate, so that's why we went with the total worst cases for '19 to $75 million. But I would expect some of that to be mitigated during -- either before, but more likely during the course of 2019.
