Yes. So, let me just start with, as we think about 2020, obviously performance in ‘19 becomes very relevant. So, where we are today, we continue to see strength in our core business. We continue to lead in virtually every tumor in which we are promoting. And as you think about our core tumors, the large tumors, first-line metastatic melanoma, second-line renal cell, second-line HCC, we continue to see I-O shares at or greater than 50%. And then, we've talked a lot about the two big growth drivers that we have for this year, which are notably first-line renal cell and adjuvant melanoma. And again, there, very happy with the continued performance of the teams. In first-line renal cell in the U.S., we are holding share at around 35%. Obviously, we have seen some impact of I-O plus TKI, mainly in the favorable patients less so in intermediate and poor, which is where we are indicated. And then, outside of the U.S., we’ve seen good uptake in key markets, notably Germany and Japan, where we have access and we expect additional access approvals later in the year. Similar story on the adjuvant melanoma side, U.S. shares still holding around 70%, in spite of competitive entries there, and outside of U.S. is still very early in terms of access. As we think about 2020, while we're very pleased with the results that we presented yesterday for Part 1a, given the competitive dynamics, the timing of data readouts, we do think there will be some pressure on Opdivo in 2020. But the growth picture becomes much clearer as you get into 2021. And exactly what that profile looks like is going to be informed obviously by the opportunities we see with 227. You will continue to see a stabilizing of the dynamics in second-line lung cancer, which is important. Just to remind you, we expect second-line lung in the U.S. to stabilize in terms of I-O eligible patients at the end of this year, little bit later as you get into ex-U.S. market. And then, clearly, we will be looking for some key study readouts that will inform that near-term growth picture, notably 9LA in lung cancer. We’ve got first line GBM, 9ER in first-line renal cell and then first-line studies in head and neck and esophageal. As you get later out, clearly, the adjuvant programs become important.
