Sure Manav, certainly when you think about the cost structure and I'll speak mostly to our rental business. Certainly, labor is an important bucket for us. And as you've heard Todd explain over the last four quarters or so, we've worked really hard over the last several years to improve the – or increase the rates at higher than I'll say historical averages and that left us not flat footed in this challenging environment and it's allowed us to continue to raise, but not in an alarming rate that maybe some of our other competitors have had to do. And we'll continue to manage that very, very appropriately. The other bucket that I'll mention is, our material costs. Certainly material cost is a big component. And as you know, we are able to amortize the rental items. So, the items that we are reusing in the business in a recurring nature garments, dust mats, mops, etcetera, shop towels. And so, we're able to amortize those and so we don't get inflation impact immediately. This amortization allows us to understand what's coming and it allows us to anticipate and that allows our global supply chain to flex when we need to, to change volumes around. And that's very important for us to be able to see ahead, and the other thing it allows us to do, it allows us to potentially get a couple of price increases in, before that, I'll say higher cost even hits our P&L. So for example, when we have – if we have cost increases in our materials, and we amortize those over 18 months. That first high – that first months of higher cost, we have [one-eighteenth] [ph] of it. The second month, we get [two-eighteenth] [ph] of it. So, it doesn't fully hit our P&L for eighteen months. We can adapt, make decisions, including pricing decisions before that fully hits us. So, we have this, we've got this nice, I'll call it, hedge in that part of the cost structure and that certainly is an important part of our cost structure. And the other thing I'll say is, certainly we've got some infrastructure and we can leverage that infrastructure pretty well with revenue growth like we've got it today and the momentum. And so, we've been able to manage all of those buckets in different ways, but quite appropriately. And then when you couple of those – the way we manage those different buckets with the initiatives that Todd spoke of to get efficiencies, labor efficiencies, productivity improvements, technology improvements, those things can really help us as we face inflation and as Todd laid out, we've got a pretty good game plan against it. As you've seen, we've in this year just ended, in a pretty difficult inflationary environment, we were able to raise our operating margins 50 basis points.
