Thomas, thanks, and congratulations for a fantastic year. Same goes certainly to Bill, really great. So hello, everybody. Thanks for joining. I hope everybody is safe and healthy. I think we had a really good year with lots of justified investment. But before I start, let me thank Karl. Karl, really a big, big, big thank you from my side as well. I think you have given Investor Relations, what should I say, a new benchmark, a new standard, if you like, for 20 years, which is amazing. So you joined in 2002. The share price was at CHF 120, as was mentioned already. And you were completely focused on that, which I always admired, and certainly, that helped me quite a bit. So thanks for that. But mostly, I would like to thank you for your great humor, was always great to be with you on the road and quite some fun. And it's really sad to see you leave. But okay, life goes on. Good. I have a lot of details. And that's why I think we should jump into it. The highlights, I think, the basic highlights you've heard, and I will anyway refer to them in a second. So let's go through to Slide 52, the next one. And there, you see really what Severin has mentioned already, the sales volatility, if you like, that we went through with the biosimilar hit, but both divisions contributed fantastically really. So we were able to come up with significant growth despite the fact that we lost really significant sales due to biosimilar impact. It was a bit less compared to 2020. But now already, you see the number coming down. And I'll come to that when I speak about the guidance. Then really, the point about the core operating profit, which moved up by 4%. And there, you see really our commitment to innovation, but also our commitment to the pipeline where we invested CHF 1.7 billion in addition, in R&D. And I will come back to that as well. So let's get to the overview on the next slide, the overview when it comes to the group performance. So let me lead you through this, and we will get to more details. I think sales, plus 9%, I think well described by Bill and Thomas, core operating profit up 4%. I will talk about the P&L in a second. Two points to mention here. Cost of sales went up significantly. I will talk about that. R&D went up, as mentioned as well. Then the core net income went up with 6%. And you know I talked about the blue bar and the numbers in the blue bar, really the growth rates and concentrates. You see now plus 6%. So you ask yourself, okay, core operating profit up 4%, core net income up 6%. What happened? Taxes. We really benefited from the resolution of tax disputes even more than we benefited in 2020. I will explain that as well. You see then from the core income to the core EPS, plus 6%. There's a small accretion effect in it in 2021 already from the repurchase of the Novartis stake of 0.4 percentage points. So even when you exclude it, round it, we stick to the 6%. But I want to bring that in. I will talk about it later on. And then the IFRS net income, which has grown by 2%, we brought more charges in, and you will see that on a specific slide later on. You see IFRS net income even declined in Swiss francs. Operating free cash flow, up 34%, fantastic and timely as we have loaded the balance sheet with debt from the repurchase of the stake, of the Novartis stake. CHF 19.4 billion is an impressive number. And you see even the free cash flow went up with 46%, so really timely and helps us out quite a bit. Good. Let's go to the core EPS development. And why do I put that forward? Because I think really it describes the performance of the company quite well. And let me show you the bridge and the ingredients, what drove the core EPS growth in 2021. You see on the left-hand side, the core EPS in 2020. You see operations, operations helped us quite a bit, yes, with an increase of 4.4 percentage points. And you see really what worked against us were losses on equity securities. And we have a participation in a company called Allakos. Share price really went down significantly before year-end. Because they announced the outcome of 2 studies, the ENIGMA Phase III trial and the KRYPTOS Phase II/Phase III trial, and both studies did not achieve statistical significance on the patient-reported symptomatic co-primary endpoints. The data was not completely conclusive, but it tended to be on the negative side, and that certainly gave us a hit. Let me mention here that, in fact, I think we have sold quite a stake on Allakos already, and we have a significant cash return with that participation. So far, so good. We will see how it further develops. But it worked against us. And then you see really the effective tax rate change. In fact, it was not really a tax rate change. It was really impacts from the resolution of tax disputes, but that gave us a boost of plus 3.3 percentage points, with certainly a bold return in 2022, at least is not expected to return in 2022. So these were the major drivers, and we will come back to them again and again. Let's go to the P&L. And the P&L is on 55. Bill and Thomas gave you quite some ingredients already. I don't have to talk about the sales. Royalties and other operating income, up CHF 1.075 billion. I think Bill brought it in well, and I will have a specific slide on that very much driven by Ronapreve U.S. and higher divestment gains. We have the cost of sales, up CHF 3.7 billion. I have a slide on that. M&D, a bit driven by Diagnostics with the increase in distribution costs that Thomas mentioned. Pharma basically flat, but very much driven by, let's say, the newer members of Pharma like Spark, Flatiron and so on. Then you have R&D, CHF 1.7 billion, as mentioned. And here, CHF 1.5 billion going to Pharma for oncology, CNS, PHC, COVID-19. And as mentioned, we have started 16 Phase III trials in addition in 2021. So evidently, I think that triggers quite some investment. On the Diagnostics side, I think Thomas mentioned it, Core Lab molecular, digital COVID played into this. And G&A, you see we even came up with a savings. So really, all what we have said that we want to really find funds and put them into other cost lines, especially into R&D. I think that comes across here. Good. With that, let's go into more of the details. Of the P&L and sales, I don't want to spend a lot of time here. You see Pharma has grown by 3%. Bill explained what happened in the U.S., where we still have a significant -- had a significant biosimilar impact in 2021. I think all the other markets have grown well. And then Diagnostics was 29% growth, leads us to 9%, and the currency impact of minus 1 percentage point, which leaves us with an 8% growth in Swiss francs. I think more interesting is royalties and other operating income. And I know everybody is behind that point. What is Ronapreve really doing in our numbers and how does it show? So let me lead you through this, and you see here on that slide, casirivimab+imdevimab, and that's Ronapreve. 2020, you see we had roughly CHF 2.020 billion in royalties and other operating income, and that increased to CHF 3.049 billion in the year 2021. Let's go through the bridge. First one is the royalty income-driven by Venclexta. I think Venclexta does really, really well. We have an additional readout in 2022. You know we don't report the sales. But we report here, the royalties that we get and we enjoy this, as you can see. Outlicensing income, that's a base effect from last year from Chugai. That's why you see here a drop. And then we get to the very interesting point, other operating income, including the profit share from Ronapreve, and you see here a number of CHF 754 million. So let me explain that. CHF 654 million of the CHF 754 million are coming from Ronapreve U.S. This is basically, we don't report the sales for Ronapreve in the U.S. All we get is, if you like, a profit share for sales in the U.S., and this is mirrored here. Certainly, I think we don't expect to have significant sales in Ronapreve in the U.S. in 2022. At this stage, we will see what happens. But I would argue, it's pretty likely that we don't see that CHF 654 million again in 2022. What remains is other operating income from other products like Venclexta U.S., where we had also a profit share or [indiscernible] ex-U.S., I think that will come through certainly in the royalties and other operating income. Then we have the income from the disposal of products. When we have tail-end products, we sell them, and that's pretty steady. We had here a slight uptick compared to previous years of plus CHF 257 million. Good. With that, let's go to the cost of sales. and the cost of sales have certainly the largest deviation of all the cost lines or the expense lines in the P&L. It's also the largest deviation to consensus when I remember it well. And what you see it, really, you see the cost of sales full year 2020 and then the bridge to the cost of sales full year 2021. Let me lead you through the differences. And the first bar, red bar is really the volume increase, which is pretty intuitive, 15% volume increase. That is Pharma with 11% and Diagnostics was 30%. So that accounts for the 15%, so CHF 2.2 billion coming from that. Then we have incremental production costs for COVID. And this is Ronapreve and Atea. Let me clarify that. I'm aware of the fact that we have in the finance report on Page 22 said for incremental production costs, it's CHF 575 million. What brings, let's say, this number to CHF 615 million that we have on the slide is impairments for Atea for PP&E. They are included here. And that really, in total, gives you the CHF 615 million. Then we have the Ronapreve profit share expense. Well, you've seen the sales of Ronapreve in our numbers, roughly CHF 1.6 billion for 2021. You see now the related profit share expense to the sales. And as you might have heard that Chugai has announced already that they expect to have sales of Ronapreve of around CHF 1.6 billion in 2022, so this is a number which is pretty likely to reoccur in 2022. You see really then, let's say, the year-on-year change in Rituxan/MabThera profit share expenses, which went down as the sales went down. And then a very important point is certainly the Pharma/Diagnostic sales mix, which has changed. And whenever you project for 2022, that's definitely something you have to take into account. Good. With that, let's go to the margins. That's 59. And you see a margin decline in 2021 on the group side. I would argue nothing dramatic here. Nevertheless, I think if you understand the guidance for 2022 well, and I will come back to that. I think it's pretty clear that we further will work on the margin and on productivity and efficiencies and is justified that we will see quite a good momentum in 2022. On that front, you see also where it came from. I think really there is a decline in the Pharma margin. Well, I think on one hand, we invested into R&D. On the other hand, we had COVID-related impacts like in the cost of sales that I've explained before. And then you see on the right-hand side, Diagnostics. And let me say that, I think a fantastic margin was 22.1%. But we don't know what's going to happen with the COVID sales for Diagnostics. If they were declining on the diagnostic side, there would be certainly a little bit of a weakening here because, well, very clearly, I think COVID sales certainly contribute to the gross profit margin, and that certainly helps to cover the fixed cost. Good. With that, let's go to the core net financial result. And you see really, there was a negative impact, which increased in 2020 a minus CHF 564 million, in 2021 on the right-hand side in blue, a minus CHF 751 million. And equity securities, I've explained already with the impact from Allakos and the minus CHF 257 million. You see, interest expenses, we were able to decrease them again by CHF 95 million, so quite a significant saving for us. So it helped us to mitigate the negative effects that I've described before. But I have to say in 2022, certainly, we expect additional financing costs for the repurchase of the Novartis stake of roughly CHF 330 million. I'll come back to that. But very, very clearly, it is clearly to expect that this green bar that you see here will turn into a red bar in the course of 2021. Good. With that, let's go on to the tax rate. And that's, I think, another story to mention. Well, in the middle of this slide, you see the blue bars. And the blue bars are the adjusted, if you like, the underlying group core tax rates for 2020 and 2021. And I would argue they are both very comparable, so 18.6% compared to 17.8% in 2021. But what we're also seeing is in 2020 and in 2021, we experienced positive and even enjoyed positive impacts from the resolution of tax disputes, which certainly led to the release of provisions. And the extend in 2020 was CHF 317 million positive, if you like, which helped us on the profit side. And in 2021, that was even higher at CHF 697 million. And as you can imagine, as the tax disputes are all related to authorities, well, it's not like that we expect something like this to happen in 2022, which means that I expect that the group core tax rate will go to around 18% in 2022, so another effect which will certainly mitigate the growth of core EPS. With that, let's go to the noncore items and the IFRS income. I want to cut that short. Core operating profit growth of 4%, you have seen. I'm talking about constant rates here. Let's say, the global restructuring plans, we have booked additional charges, which certainly lead to additional savings moving forward. Amortization of intangible assets, you see here a saving of CHF 200 million, CHF 194 million to be precise, compared to last year. I can say that the Esbriet amortization came to an end, end of September, so there will be a positive impact in 2021 -- 2022 from that. Then you see really a minor impact on the impairment of intangible assets and on M&A and alliance transactions. And you see a larger impact in legal and environmental. It was positive in 2020. That was the release of the Accutane provisions, was roughly CHF 300 million positive. And then you see in 2021, these are additional environmental provisions that we have taken for certain sites. You see the IFRS operating profit basically flat with that, and you bring the financial effects and the tax effect based on what you've seen before in and you end up with an IFRS net income with an increase of 2% in constant rates and minus 1% in Swiss francs. Good. With that, I think really to Slide 63, which is just summarizing what I've explained. And I would like to go straight to the cash flow on 65. First of all, I think it was a strong year. You can see all divisions ramped up their cash generation quite significantly, which is certainly very pleasing. As I said, it comes at the right time. So I think a good thing here. Let's go a little bit to the ingredients on the next slide. Here, you see really where it came from. You see the first green bar, the operating profit net of cash adjustments. And you would argue, well, it's on one hand, really operations, so the operational profit, and on top of that, provisions that we have taken. Then you see really the net working capital movement, and that is very much driven by the accounts receivable -- the accounts payable, sorry. And then you see the investments in PP&E. And here, Chugai and Diagnostics have driven that number up and then you see the investments in intangible assets, which came down compared to last year, which could trigger the question, well, did you invest enough into innovation? Well, you've seen the ramp-up in R&D. But if you just look at the balance sheet and M&A and equity investments and all of that, the difference to last year is not very big. Good. With this, let's go to the net debt development. Yes, and we started into the year, you see on the left-hand side, with net debt of CHF 1.9 billion. And the question was very justified. Would you get net cash positive? And we did. And the sole reason why that is, is that we did the share repurchase. But let me lead you through the bridge. CHF 1.9 billion net debt at the beginning of the year, then the operating free cash flow was CHF 19.4 billion. You see really the net operating free cash flow with taxes and treasury that we have paid. And then you see that large red bar, the minus CHF 32 billion, and this is driven by the dividends paid really for the year 2020. And then you see the share repurchase of CHF 19 billion, which comes in here, which leaves us with a net debt position of CHF 18.2 billion. Below, you see really the comparison, the investments in innovation with intangible assets, equity, M&A in total, and you see the difference is CHF 1.2 billion. With that, let's go to the balance sheet. And I don't want to go through every detail here. You see on the left-hand side really the assets. Cash and marketable security is pretty stable. And that's a good cash generation, I can say. Then the other current assets. Inventories went up by CHF 521 million, accounts receivables, up by CHF 652 million, other current assets up by CHF 648 million. You see the noncurrent assets, that's basically PP&E, so investment in plant, property and equipment of CHF 1 billion ramp-up. And then the goodwill, which increased by CHF 1.56 billion, certainly driven by the acquisitions of GenMark and TIB Molbiol. And then I think which is much more interesting is the right-hand side, the liabilities and equity. And the short term, the current liabilities really went up by short-term debt, CHF 11.1 billion, which is the bridge for doing the Novartis stake repurchase. And then the long-term debt went up by roughly USD 6 billion, CHF 5.8 billion. This were USD 6 billion bonds that we've issued and that we brought in already, I think, at a very attractive rate, which is good. You see the equity has reduced to 31%. That's the equity ratio now. We feel comfortable with that. But it's the consequence of terminating the shares of the repurchase, which has happened, I think, a couple of days ago now also legally. We had to account for it already last year. But legally, it was not done yet, so that's done now. And now we have a much lower share base, if you like, at least from a number point of view than before. And I'll come to this. Good. Let's get to the outlook. Outlook first on currencies. And I want to cut that short. You see really what the currency impact has been for the full year, minus 1 percentage point on sales, minus 2 percentage points on the core operating profit, minus 3 percentage points on core EPS. And you see what it was driven by on the left-hand side, I think the negative impact of the U.S. dollar got smaller in the course of 2021. And the positive impact of the euro got smaller as well, if you like. So I think really these 2 mitigating things really came together. I think really you see our projection here on the right-hand side of the slide. If we expect that all the currency rates that we have had at the end of the year 2021 remain stable in the course of 2022, which is certainly completely unlikely, but if that were the case, I think the currency impact would be between minus 2 percentage points to minus 4 percentage points on sales, core operating profit and core EPS. Good. And when I say core EPS, it's a perfect segue into the slide 71. And that's now really for everybody who wants to come up with proper projections for 2022, and I want to set the stage well that you can do that. You know the core EPS projections are really operating with a constant rate in a constant rate environment, and I want to deliver you now really that one. Really, you see really the starting point on the left-hand side. It's the core EPS 2021 as reported, excluding the accretion effect from the repurchase. The share repurchase impact is CHF 0.07 and leads you to the core EPS of 2021 as reported of CHF 19.81. Now when you go on Page 60 of the financial report, you will see a currency loss of CHF 232 million incorporated into that number. When you deduct the taxes, you get to exactly CHF 200 million. And this is what you add to the net income for Roche shareholders of CHF 17.40 billion. Furthermore, you have to deduct CHF 1 million for the interest of noncontrolling interest shares of the group net income. And that leaves you a net income for Roche shareholders used to calculate in a constant rate environment for 2022 for -- of CHF 17.239 billion. You deduct this through 860 million shares, to be very precise, 859,867,000 shares, and that leaves you then with the 20.05 which is outlined here on that slide. Good. Now let me clarify on the next slide the accretion effect and how we got to the accretion effect for 2022. You see on the left-hand side of the slide what I've explained already, the accretion effect for 2021, with plus 0.4 percentage points that you see in that pink arrow. Now let's get to the rest -- to the left-hand side -- the right-hand side with the 4.4 percentage points. First of all, I think there's the number of shares which go down, and they go down to 810 million shares. Don't forget, there's also an LTI impact incorporated into this. And you find that on the Pages 167 of our finance report where it is outlined. So you get to 810 million. When you do just use the 810 million and you take the profits that you would project and you just put it really on this 810 million, you have automatically an accretion impact of 6% roughly. What comes certainly in addition is the cost of financing assumption. And the cost of financing assmption I've mentioned already, we expect to have CHF 330 million more financing costs in the course of 2022. This number can vary. We're happy to update you during the year where we are. When you take that into account and the number of shares that I've mentioned, you get to a counter effect, the mitigating effect of 0.34, which then leads you to a core EPS 2021 after the repurchase impact in 2022 of 20.69 Certainly, I think if you're going to adjust well, you have to bring the currency impact in as well. That leads to me now to the outlook. And the outlook, Severin went through this. But let me make a couple of points, which just to get it completely straight. This outlook contains the assumptions that our COVID sales from 2021 of roughly CHF 7 billion decline to CHF 5 billion in 2022. So we lose roughly CHF 2 billion COVID sales baked in into that guidance. We will lose furthermore around CHF 2.5 billion in sales due to the biosimilar competition in 2022. So really on the sales side, we expect to lose roughly CHF 4.5 billion, and this is incorporated into that guidance. On the core EPS growth side, well, what we have included, and that's on that slide here, the accretion effect of 4.4 percentage points. But in addition, we assume that the group core tax rate goes to around 18%, which is a significant step upwards. And in addition, we also expect that the financing costs go up by CHF 330 million. Therefore, and I don't have to say anything about the dividend outlook. Good. I think that leads me to the end of my part, and we are happy to take your questions.
