Sure Rob. Hey, this is Steve. Obviously, there's a lot of volatility in the commodity markets. Our guidance takes into consideration what we believe will play out for 2021. And as you know, we do hedge and we take coverage usually on the seven to nine months-time horizon and typically stay on the long end of that. So, we do believe we have good visibility for the rest of 2021. There are a few things that we can't cover, a little more near-term from some of the packaging area. And you are seeing a lot of volatility and inflation in packaging, particularly around the corrugated area and arena. But like I say, we do feel like we have decent visibility. Ralph said in his comments, there are several levers we can pull, I think being one of those that we are looking at, efficiencies across our bakeries as well as other cost initiatives. So, I do feel pretty good about the guidance range we have out there. And, obviously due to the volatility and the way things moved so quickly, as the year progresses, we'll be able to exchange the guidance if necessary, but I think given the point we're at, we feel pretty comfortable with that. Looking into 2022, obviously, we're not prepared to give guidance for 2022, but the reality is when you look at what's driving kind of the commodity inflation, a lot of that is not necessarily wheat. I mean, the wheat crop is in pretty decent shape, but it's other grains like corn and beans, and it's more of a global market. We are seeing, China back into that market in a big way. And just -- and as grains turn to feed grains, and there is tightness on availability of the supply, then that starts to impact things like wheat and other grain crops. So, the reality is that today's prices, if we had to go out and cover, it would be significant commodity inflation, but we still have a lot of runway with regard to the corn crop, the bean crop. We'll cycle a wheat crop, but we just thought it was important to get that out there from a transparency perspective.
