Yes, so as you know, the eval tools, when they do go out, the inventory stays in our inventory number reports, so it basically stays in our wph number. So 1 tool did convert and that was the announcement we made a few weeks back. And there are 2 additional evals out there. Going forward, the advantage of the commonality in this platform that shares some commonality with the Purion H -- or Purion XE, we can manage inventory because rather than driving one-for-one, on forecast, we can -- if we've got order for an XE -- or forecast for an XE or forecast for an M, we can drive one, for example, because there's some commonality there. So we're being very careful in terms of moving forward what we're driving for inventory, but we're also making sure that we're going to be ready for the ramp. So what we use, Patrick, is planning bombs basically for long lead material, which is tough to get, and the rest of material we keep within about 60- to 90-day window, so we can quickly get it.
Patrick J. Ho - Stifel, Nicolaus & Co., Inc., Research Division: Great. That's really helpful. And my second question on a big picture basis, obviously, you guys are generally biased towards memory just historically with your customer base, but the medium current market, obviously, has a big opportunity on both the logic and foundry side of things. Can you give a little detail on the type of applications that the Purion M is targeting that will hopefully allow you guys to break into more of the foundry segment as you mentioned?
