Great. Thank you. Listen, I'll answer the A&P question and then pass it to Tobias to do your follow-up in the Q1 guidance. So first of all, on A&P I just want to be very clear that we are absolutely committed to investing in our brands and we believe investing in A&P is important. Also, investing in R&D and in our case, in the expert side of our business model, which is really important in oral health with dentists, but also with pharmacists with our OTC business. We do start A&P as a percent of sales in a relatively healthy place at 17.9%. But as you said, this year, we grew A&P 3% and as the year goes on we're very active in the way we manage A&P and ensure we get the best returns. So for example, in 2023, our A&P investment will find oral health was very strong, and you've seen that come out in results. And actually, we continue to invest in VMS, and we're able to take share, an example on emergency, which to be showed in the presentation in a declining market, which I think positions us and strengthens us for the future. On the contrary, in respiratory in the US, where we saw lower incidences and some disruption due to some ingredient questions on PE, Phenylephrine, we actually pulled back from our A&P spend there, is a conscious choice because we feel like the returns weren't there in that level of market. So -- and so when we look across the portfolio, we are actively managing that and making sure that we're investing for growth and we're investing in the right places, but not investing just to invest. And then as you said, within that, there is efficiencies we're always looking to be more efficient in our non-working A&P, and we see that obviously grow slower than overall A&P. So there's a number of dynamics in there. But we feel good about the investment, as Tobias said earlier, we expect in 2024 to continue to invest in A&P and drive growth and invested really higher than this year.
