Yes, depending on which piece you are comparing it to or what base period. But typically, the drag we are seeing is the tariffs add a couple of million dollars per quarter. The freight, which is primarily a freight rate increase is probably in that same footprint. Some of the manufacturing variances, which at least in Q4, still have the incurred variances from as early as October of last year when we were still a little deeper in the grips of the pandemic. So as we move forward, beyond there that those manufacturing variances going into, let's say, particularly as we move into Q2, where we have the current levels of operations and volume benefiting, you're going to see a nice expansion there. Some of the other things that will drive margin expansion as we go through the course of this year is going to be a number of price increases, which we have done recently, which as they move through the order book, will start to impact late in, let's say, June of this year. So starting this upcoming month, you'll start to see some pricing moving through. You're going to see the fact that for all of our factories moving up from some, let's call them, deep and COVID type utilization rates where you were running at 50% to 70% capacity, we'll move back into their normal 80-plus percent capacity. So across the -- our factories, you would expect to see that. And the one that's been the biggest drag, and this has been well-known and well-publicized when we bought the NorthStar business, which included 2 factories in Springfield, Missouri. We knew that those factories based on the NorthStar book of business we're drying up quickly. But we bought them for their TPPL capacity and not their book of business. So as we've made that integration move some EnerSys product in there, done some transitions of their product to be closer to their end customers. And then we've added the high-speed line in the second of their 2 factories. Right now, that drag has been $5 million to $6 million per quarter, which we expect to abate as we go through the end of this fiscal year. So that's a big piece.
