Yeah, Warren, this is TJ. I'll do my best there. So I think at a very high level, we would expect the margin rate to be up for the year, largely driven by the cost of goods sold initiatives that we have in place as part of the Transform the Foundation. Additionally, here in the early part of the year, we continue to see favorability from a transportation standpoint. So transportation rates that are embedded in our inventory are lower year-over-year, so that's a net positive. On the flip side, as Martin mentioned, we are seeing slightly more promotional activity here in the front part of the year. So those are the key elements from a margin perspective. And then the last one would be B&O deleveraged, which is really going to follow sales. So if you think about how we just talked about the sales trend or what the embedded sales trend is for the year, I would expect us to have cost of goods sold initiative benefit throughout the majority of the year, especially the first three quarters. When we get to the fourth quarter, we start to anniversary what just happened in this most recent fourth quarter. So it's more present in the first three quarters of the year. The transportation opportunity, we still think, is available to us in first quarter and potentially second. We don't necessarily have a crystal ball in where transportation rates will go in the back half of the year. So that benefit likely impacts spring in a positive way. From a promotional standpoint, Martin mentioned, we do expect to be a little more promotional than last year, here in the first quarter. As we move through the year, if our assumptions are correct, and the intimates market stabilizes, hopefully that promotional need abates a little bit. And then as I mentioned, B&O will track where sales are going and what sales trends look like. So down mid-single digits here in the first quarter, down low single for the year, or slightly better as we move through Q2, Q3, and Q4. So that's kind of how I would think about the key drivers. I do think there's an opportunity for the margin rate just in total, obviously, to be up in the first quarter and potentially up in the second and third. We had a very strong gross margin performance in the fourth quarter that we just came across. So I think anniversarying that might be a little bit more challenging, but we'll see what we can do when we get there. So I feel very good about the gross margin opportunity, again, on lower sales based on how the teams are managing inventories in our stores and our distribution centers.
