Yes. Thank you, Mark. Yes, the last year was quite interesting with the forward buy, if you will, as healthcare systems strived to get some inventory and also the patient level longer scripts have been given, so we had this $400 million roughly effect of forward buy, or stocking in quarter one and then they de-stocked in quarter two. That’s roughly three points on our quarter. So of course then quarter two would have the reversed positive effect. In other effects we have in quarter two is that, Lucentis, basically many patients skipped or doctors skipped one injection, that’s now fully back. So quarter two, we should see some good growth. And so the first half, I would say, we do expect to be broadly in line with prior year, maybe low single-digit growth as totality, I had first declared in quarter one and then some good quarter in quarter two is the expectation. That - this is broadly in line with prior year, especially what we have seen in the last two quarters. Now, if you think about the second half of 2020, quarter three was zero, quarter four was plus one, and that was the environment that we expect the next couple of quarters to be in. So that’s why we believe that is a reasonable scenario. Of course it is unprecedented volatility and therefore we have to plan in different scenarios. So then, as you say, in the second half, we do expect some very good growth, but again we talk ranges and have to see how quickly then the healthcare systems open up. So I think that phasing of half one, half two, and then if you have to do this quarter one stocking, quarter two de-stocking of last year, should give good feeling for how to model the quarters. I don’t want to get into Innovative Medicines, where the Sandoz I think we get too granular, but you have seen last year the quarter one, quarter two of both divisions and I think that should be helpful.
