Yeah, we've been monitoring that carefully. I think you and I talked about it over the summer at your conference, Ric. We haven't seen a significant disruption to our supply chain. Now, whether that's luck or good planning, we could debate that intensively. Maybe we'll do that at your conference when I see you in a couple of weeks. But look, what I would say is, we believe we have some of the best CEOs in the sector. It's not accidental when you've got Steve Smith, Alex Gellman, Raul Martynek, [Indiscernible] and in some of the other great leaders we have. They plan for this. They purchase years in advance. So whether it's steel or generators, or whether it's connectors, or whether it's optical light switching gear, we've been ahead of that curve. When you manage $50 billion of assets globally, and you've got massive purchasing power, we can stand with vendors and say, look, we need to get to the frontal line. And we've been able to do that. So what surprised me in looking back, Ric in 2021 is our supply chain was not impacted. If you look across all of our business units, very few companies missed their new construction budgets. And most importantly, we also, what was very interesting is we came in under CapEx, so our budgeted CapEx spend for ’21 against what we actually spent looking across all of our portfolio companies, we actually came in under budget, I did not expect that. I expected us to have to spend more money to execute our greenfield business plan in 2021. So the setup is good for ‘22. We've just like, as Jacky said, we came out of our budgeting cycles, we know what's happening. We're touching these portfolio companies every week, we're getting KPIs and dashboards, we have granular data down to the datacenter down to the tower, down to the ultimately to the new fiber routes that we're building. And we have strong control of our costing, which is a function of us having incredibly good back office systems, which that's something we started doing back in 2003. So having good control the data, and having those metrics at our fingertips has been helpful. But I don't know, Jacky, you're looking at the dashboards alongside of me. I mean, anything that I missed in terms of what Ric just said?
