Good question, Pavel. I think, you know -- as you look at the production base today and it was a slide that we had at the Capital Markets Day, we've grown the production from this 2016 at just over 20,000 barrels a day up to a target this year of 69,000 to 73,000; so significant growth, but actually we diversified it from simply one country, Ghana to the Gulf of Mexico, Equatorial Guinea and Ghana. So from a production perspective, I think we've built the necessary diversification and now we've got multiple fields as well. And if you look at the diversification from the Gulf of Mexico, the portfolio there, Equatorial Guinea, the same; so we've gone from literally two fields in Ghana to having that right distribution. And that enables us you know despite the challenges in Ghana to keep our production guidance for the year actually. So, I feel good about that. We've got a world class development in Mauritania and Senegal, which as we discussed, is going to be a near-term source of value-add through the sell-down process but it's a long-term growth opportunity and that has scale and it has focus. So it is -- you can't do many of these big projects and having a company like BP lead is a way for us to sort of remain focused in what we do. And then, you've rightly talked about the depth of the Basin-Opening Exploration where we have multiple opportunities. I think we've got the right depth of that portfolio now. And the bit that I'm most excited about, which is the ILX portfolio, has got real depths now. We're talking about a prospect inventory of five years drilling four to five wells per year, targeting 65 million to 100 million barrels of resource, which is -- the 2P currently in Gulf of Mexico is 82 million, I think So, it gives you a sense of -- I think, we've got real diversification now but it's thematic. We're clear about where the production growth is going to come from, we're clear about where the long-term growth is going to come -- from gas, and we're clear about how we can deliver a continuing near-term production growth from the ILX while retaining the asymmetric upside from the base and opening opportunities. So, yes, hope we've got the balance, right? I believe we're pretty well-balanced today, and the important point is now to deliver. That's a great portfolio, we just need to programmatically deliver the cash, and that means managing the capital.
