Yes. Carla this is Rob. In terms of those costs, again, I think, that as you look through those, I broke them down into the $25 million related to utilization and the $22 million that was not related to utilization. Of that $22 million, again, a big chunk of that was related to raw write-off related to 2019 crop and settling of those contracts. And so, I would not expect anything material out of that to recur or extend, other than there may be some minor true-ups here that we clean up in Q1, but it's going to be much smaller than what we saw previously. And then, I said, there were some capital write-offs that we had in the quarter that don't anticipate those will recur. And then, transportation warehousing, I said, that expect those to improve versus what we saw in Q4, may still have some, but they'll be better. On the utilization costs, the $25 million of utilization costs, as Tom and I’ve talked through, it's really tough to predict and to forecast what's going to happen, because those are largely driven by a couple of things. One, what's happening on the demand signal. And two, what's happening in terms of employee health, as they show up for work. We can keep them safe at work and keep them healthy at work. But outside of work, as they circulate in the community, they may get sick and so we may have unexpected shutdowns of plants. And so, that's what's driving that $25 million as that utilization that is tied to both of those issues. So that's the one that I would expect will have some recurrence. Hopefully, we're getting better and smarter at managing those costs. But that's the one where there's a risk I think.
