Terence, this is Bertrand. I'm my losing voice today, so hopefully, you can hear my answer well. So first of all, in terms of the amount we are investing in R&D, I would say that about half of the -- any divisional R&D expense is probably geared toward 450 and leading-edge process carrier development. Now again, a lot of what we do in terms of development in the Microenvironment division really is CapEx, because as you know, in the molded products, what we do is, really, we develop new molds, and we invest a lot in those molds. So it's really a CapEx investment as opposed to an expense -- an R&D expense. In terms of the recent development in 450, I mean, obviously, as Gideon mentioned earlier, we were very pleased with the announcement of the collaboration between Intel and ASML. I think what it really means is that the pace of adoption of 450 is going to pick up in intensity, and that's really good news for us. It's good news, because we have been hoping, and we have been actually planning for a fast-paced adoption of this technology, and this is happening, and we are ready. As you'll remember, we've been an early participant in this effort. So we have very extensive collaborations ongoing with all of the leading players in the industry. We've been learning a lot over the last few years, and our design is really incorporating all of the learning that we've been able to gather through the ecosystem, number one, but also all of the learning that we've been gathering working on the leading-edge, 300-millimeter FOUPs, where as you know, we benefit from a commanding market share. So I think that, again, we are really welcoming the increased pace of adoption in 450.
