If I may add something here, you talk about the role of technology and innovation in transformation. Basically transformation takes time and energy and investment for the long term. It's important to recognize that, in the past, we were pushing technology and now we're trying to be more mindful of the market and understand how those new materials and products will be used in the marketplace and where there is the most potential for growth for those materials.
One other important element of this is making sure that we strengthen the foundation of the existing industry, because in many cases co-location makes a lot of sense from many different perspectives, because of savings, utilities in place, water treatment, and other things in those co-locations.
So it's important to have both a strong foundation, which is the traditional products, but also have the transformation with new products, together. So transformation will take both basically: true competitiveness and also a long-term investment in transformation. You don't change a sector or transform it in five years. It takes a while.
