Sure. Thanks, Gary. And John, to get to how 2019 is profiling in the memory space, let me start with what we saw in 2018 and use that as a jumping off point to make some comparative statements about how we see the market profiling in 2019. We’ll probably not going to be point specific on how 2018 ended up because Gartner’s going to come out in a month or two with those estimates. But, we definitely saw 2018 up over ‘17, definitely has a 5 handle on it. And as you indicated, it was a strong memory growth year. We think as 2018 settled, 60% of the spend in the market was memory related, 40% -- about 40% was foundry logic related. Within memory, we saw the NAND DRAM spend very balanced. As we look forward into 2019 and Gary’s prepared comments, he said, year-over-year, WFE in ‘19 will be down. Memory will be down by a good amount. We expect foundry logic to be flat to up a little bit. So, as 2019 shakes out, we expect foundry logic to be greater than memory. Overall, the market will be down mid to high teens. And as we look at the market between NAND and DRAM, we see it profiling very similar to ‘18 and being balanced. In terms of the second half and come back in the market. I think, we want to set expectations for a slow, gradual recovery off of these levels. While we're having conversations with customers and we see positive lead indicators, we think it's prudent in this environment to set those expectations for a slow, gradual recovery. As we look into the back half of the year, inventory levels come down faster than we expect, utilizations come up and price stability, those would all create the environmentals for a more robust second half. And if that scenario materializes, then we would benefit significantly from that environment. And then, I wanted to come back to C.J.'s original question, because now I think I understand a bit of what he was asking for. And I apologize, C.J. Let me help shape the revenues this year to I think get at the question you were asking. Off of the levels we guided in Q2, we see our Semi Systems Group flattish on a quarterly basis into the back part of the year. The run rate of our Display business in Q2 will be below the annual average. So, we would see -- expect to see that growing into the back part of the year. And then, AGS will have its normal seasonal profile and be higher into Q3 and Q4. So, hopefully, that helps giving you a bit of a profile and color. And then, the gross margin part of your question again, we expected that to incrementally step up in Q3 and again into Q4.
