So on the U.S. market, I mean, again, when I look globally, we've said – in both transactions, we said that we think we will grow On-X double-digit. We will grow JOTEC double-digit globally. So if you kind of zoom into the U.S., we obviously don't have JOTEC, here yet. It's going to take us several years to get those products into the market. But we expect On-X to be the big driver of growth, which you saw this quarter with 23% growth. We also saw a nice rebound in Glue back to kind of mid-single digits, which was nice to see. And then we saw cardiac tissue at 8%, vascular tissue kind of down at 1%. So I think for the U.S., we've also got some new PhotoFix products coming out. But for the U.S., I think we've targeted kind of mid single digit and we are expecting to get our growth in the next few years until the On-X products come more internationally. And that's pretty much with the U.S. The U.S. had a very good quarter, this quarter, and I think that's kind of what we expected to see. And maybe, I'll let Ashley take the other, the SG&A and the gross margin. The one comment on gross margin that I've talked about previously, you've got a couple of kind of underlying tailwinds on gross margin. Number one is the expansion in the – our direct strategy. As we go direct in the country, we mentioned with the CryoLife products, so Italy, Spain, Poland, we kind of eliminate the middleman and get end-user gross margin. So that's one piece. A second piece, as we bring down the road, as we bring the JOTEC products to the U.S., those are very high margin products in the U.S. marketplace. So that's an upflow, but again, that's further away. I think the other big strategic pieces, our head of operations, I brought in from Baxter. He used to run Baxter's entire supply chain. He worked from Medtronic. He's a very strong operational leader. The Austin, the legacy On-X facility, CryoLife and JOTEC, there was really never any cost down on product cost. And I see significant opportunity over the five years to bring our product cost down to help drive margin aside from anything else, we do it with mix, direct and new products. Ashley, maybe you can take the other two.
