Sure. So, when we think about three component -- the three largest components of the cost of service pool, one will be labor. The other one will be food purchasing. And the other one -- the other -- last one will be utilities. Look, on food servicing -- and Brad touched on labor -- so let me hit on food servicing for a moment. We're one of the top 20 providers of food servicing in the country in terms of purchasers, right? So, we have massive scale and I don't think the marketplace necessarily appreciates that, but it's substantial scale. So, when we think about cost of servicing, and we think about it on a per unit basis heading into 2022, we expect that on a per unit basis to continue to come down, right, just partially as a function of occupancy, increasing at a relatively higher pace than we expect cost increase. We do expect to have some inflationary movement. However, we're able to ameliorate the substantial portion of that. So, as opposed to, the headline numbers, you're seeing of 79%, whether it be CPI or PPI, and we're talking low single digits, which would frankly not be drastically different than what we've seen in the past. So, we'll continue to monitor it, but I don't think we should look at anything that impacts margin degradation to that point. Now, when you look at things at the top line at a consolidated level for Target, just to bear this in mind, I think it's worth mentioning that we did have TCPL last year, right, included in 2021. And so, we won't have that carrying forward into 2022. So, at an aggregate level, you'll see a little bit of movement on the margin. Largely, it's a function now of having costless revenue last year. So, just bear that in mind. I think you know that, but just reminding you.
