Absolutely, Gary, it's Varun out here. Two years ago, as you rightly pointed out, we pivoted to an operational excellence mode. And ever since that, we've essentially been driving productivity through integration. And these programs you really see in terms of how our North American business has taken the lead on that front. Just look at the fourth quarter operating expenses, that business, yes, we certainly had challenges in terms of what the VMT has been in, so collision rates have come down. But as we think about how our collision business has performed relative to the data we're getting in from CCC, we're performing much better than what the repairable claims are out there. So that's kind of good. But really, it is the productivity piece of it that our North American leadership team has just did an outstanding job. You then kind of move over to say for example, the next large component of our overall business, and that's in Europe. And Europe also has kind of begun to make some progress, they'll be setting so some operating expenses come down in the fourth quarter, there's a lot more productivity to go get out there. And that really is the overall 1 LKQ program. We need to make investments out there, for example in the European ERP program, setting up a back office for example, that really the longer-term productivity really is from our European business. And that is something that we know our European team has a laser like focus in making sure that they certainly follow from, within the portfolio companies, as we shared best practices between our businesses and our divisions, I know our North American leadership team has spent time with our European team also. It's just one thing Nick and I kind of pushing and pulling certain levers. But as the peers speak with one another, largely, it's the base similar business, it's the distribution business, and that certainly has helped a lot also. But yes, you're right, overall productivity programs, every business of ours, every function of ours has productivity programs to essentially offset the inflationary pressures that typically come around in any case, but it's the nimbleness and the agility that we're tremendously proud of, and that really came through in spades, with the onset of the pandemic. I hope that response to your question.
