First of all, Advanced Materials had a great first half of the year with 10% earnings growth and very much of strategy. We’ve told you all along that our focus in this business is driving volume and mix upgrade every year, consistently for many years now, and we demonstrated another strong performance on that front. So, as you look at the margins in AM, you have margins actually improving as that mix upgrade delivers value year-over-year and sequentially. That’s then been offset by the increased gross spend. And just to step back to corporate level for a second, we’ve told you that we are increasing our growth spend between the new operating assets we’re bringing on line like Tritan and PVB assets in AM as well as Crystex plant and ketones expansion in AFP. So, overall, we’re at the high end of that range of about $50 million of growth spend for the Company, on an annual basis. That actually divides out across the segments, roughly $25 million in AM, $20 million in AFP, and about $5 million in Fibers of additional spend. So, when you take that sort of $25 million and realize it’s ramping up, so not much of that was in the first quarter, but it’s ramping up in the third through fourth. The margins of mix improvement that we delivered year-over-year and sequentially, were offset by about a 100 basis points of higher gross spend in the second quarter. So, that sort of nets each other out. And the great thing about that is the trends in the fixed cost leverage as we forward. So, we don’t expect the same step up in investment -- growth investments next year across the Company that you are seeing this year. There’ll be some carryover from this year of course, but there is no big next step in terms of gross margin lever. So that sort of deals with some of the margin story. On the actual pricing side of the equation, David. We had great success in increasing prices with raw materials on the polyester side of the equation and they are doing just fine. The spreads are holding in quite well. The place where we offset that is as we discussed at Innovation Day, we intentionally had some price concessions in the interlayer business in the annual contract negotiations last fall to achieve significantly improved mix on our heads-up display and acoustic sales that are much higher margins than our standard. So, while we gave up some price, we gained significantly on the mix and earnings as a result of that, which is consistent with our strategy. So, everything in AM is playing out exactly as we intended, driving a lot of earnings growth. And from both the first half of the year or on a full year basis being at the high end of our guidance range is very attractive growth.
