So Charles, thanks for the questions. The first question will go to Enno. The second question is a very simple answer because we are building a long-term value company. And with this, the short-term optimization of EBITDA would just not be the right service to our investors. And with this, we are investing into disruptive platforms, for example, HAL is a machine learning platform in antibodies when these technologies are ripe to be progressed forward or we are bringing PanHunter and PanOmics to the market when they are needed in the industry. So there is no, I would say, at this stage, tailoring of our EBITDA, for example, that we are handling around €100 million or whatever, it is a function of what is needed to make this company long-term successful. And it's, of course, fantastic that we are discussing this, not on a "closely breakeven situation". We are discussing this on a highly cash-generating platform. We are discussing this on a highly profitable company. And we are discussing this on a company, which has spent more money in R&D than ever before in 2020, and will spend more money in R&D in '21 because of this full commitment for our long-term plans. And that's really the answer to our investors who are fully supporting this, when you look at, for example, the endorsement of Novo or Mubadala, to build this long-term vision of a company that is profitable, but also invests in disruptive platforms. Sorry for the long answer, but it really goes to the heart of what we are building, and it's clearly not short-term. It is very long term. And when it comes to the guidance range of milestones, I think, you should see a year with more milestones since last year. That's the guidance I can give you. And at the other side, you should see milestones are defining our business. Milestones are volatile, will continue to be volatile and really should be seen as something where there's a massive upside in the company every year. But even if they would not come, this company would have a very strong year also from its EBITDA perspective. And I think that's the beauty of that. And on the Exscientia question, how we deal with this situation in general, I'll give over to Enno, but let me first mention that at this stage, we have more than 20 fantastic co-owning companies and not only one company, which is, of course, especially great because it was one of our first investments, that's Exscientia.
