Stephen, good afternoon. Thank you for both of those questions. First, on instrument growth versus recurring, you saw in the fourth quarter that recurring revenues were double digits, instruments were mid single digits. And I think, going forward also, I mean, if you just think through what we are thinking, what we are hoping to see in the future, I mean, we expect that pharma continues, and you should see a similar sort of mix going forward as well. If Pharma continues its trend and as other end markets recover, we expect a bit of upside to it. And if you just turn a bit towards, I think, rather than giving you ratios, let me give you a bit of specifics on how one could think about it. If you just take off, I think of applications in pharma for both small and large molecules, and let me just give you a bit of the portfolio that goes towards that. Right? So small molecules, I mean, as that rises, especially as generics consumption, and products for COVID, especially therapeutics, small molecule therapeutics rise, we see our LC portfolio with Arc HPLC in particular, going up. Then if you turn to large molecules, you can start with consumables and then the reason I'm giving you the specifics is, just to give you color that on both fronts there is reason to believe that that we should see some optimistic development. And on the consumable side for large molecules first, I mean, our ACQUITY columns for UPLC have been designed in particular for large molecules. This starts with proteins, with peptides, glycans and also oligos. The Premier getting launched first as a column, the technologies is has got very good traction, especially for oligonucleotide applications and now it goes into the instrument space. So it's rather broad based, if I just take the LC example, both on the UPLC side and the HPLC side. And from our spec, as you already know, BioAccord and QDa have done pretty well for large molecule applications in Q4, so very, very broad based. I would not speculate on one or the other, but I would say, Q4 gives you a good indication of what we should see even going forward, if not better. Now, in terms of large orders, and to give you give you color on my comment on large orders. Previously, you see with the LC replacement initiatives we've had some customers come in and asked us to replace their full fleet. And that has resulted in some of the largest orders and this is why I'm rather optimistic about this initiative. So that gives you more color. On the chemicals piece, I'm not sure what you're referring to the 14%. So I don't know Mike, if you have any comments on that I don't know what that is referring to the chemicals go to 14%.
