Thanks, Patrick, and we will take [indiscernible] [Roland] this question just before going to the margin, so questions on OEM instrumentation in China. Obviously, Patrick, I'd like to have a crystal ball. It's obviously extremely challenging those days to forecast given the volatility. However, as we have said in Q2, we strongly believe that our OEM business is now normalizing towards its pre-COVID time. So I expect a normal, let's say, OEM range of revenues around $70 million to $80 million in a normalized environment. China, it is obvious that a lot of players in the market were expecting a sequential improvement of the Chinese market starting in Q1 of this year. This has not happened. And it's clear as well that the anticorruption campaign in health care, launched by President Xi is adding to other challenges met by foreign companies on this market, pressure towards localization, delays in permission and registration from a regulatory standpoint, the so-called VBP policy. However, China is a very important market, both for life science and clinical diagnostics, it's probably already the second market in the world. So I do not see a fundamental improvement on the market in the coming six months, for example, but I believe in the long-term potential of this market because of the needs of the population and the patients locally. Obviously, foreign companies have to adapt their strategy to fit, obviously, into the Chinese priority. So, we need to keep a cool head. It's an important market. It's not going to bounce back immediately, but the long-term perspectives are good. Instrumentation, QIAGEN always said that because of the influx of tier, as we say, of instrument during the COVID period, the post-COVID period would see in many labs more trends towards placements of instruments than capital expenses in the diagnostic world. We are used to that at QIAGEN. I still believe that labs on average, continues to renew and upgrade their instrumentation every five years. There is no scientific rules here, but it's well adopted and well accepted KPI in our market. So whether it is capital sales or placement QIAGEN as the financial answers for all those options, it is true that it's a bit more constrained. But once again, we believe that the market for diagnostic life science and clinical is solid and will continue at a pretty solid growth rate as well in the coming months. Roland, moving to the margin.
