Yes. Thanks, Alastair. On net interest margin, I think I'd go back to my earlier comment. In terms of liability spreads, what we've seen coming through Fed rate adjustment has been encouraging, both in the U.S. and other dollar-linked currencies, most notably in Hong Kong. On the asset side, there's still a lot of liquidity chasing deals out there. We still see pricing pressure on asset spreads. I would be inclined to kind of keep a pretty consistent view, broadly in line with guidance that we provided at the end of the year in this regard. Encouraging signs, but I think we're going to stick with the guidance that we've provided at the end of the year, but hopeful. And, clearly, Alastair, if the Fed were to become even more helpful than they've already been and get another rate increase or 2 out there this year, I think that clearly would be further signs of encouragement from our perspective. On the capital front, no intention to change the target range of 12 to 13. But as we said previously, a clear preference to operate at the top end of that range in the medium term. We also said earlier that, in the medium term, we're going to operate above the top end of that range. I don't want to go down the regulatory sort of rabbit hole on this one, but there are, obviously, a number of factors that are out there that we still need to work through. Basel IV revisions will come upon us at some point. Hopefully, they'll have no impact, but it's an unknown at this point in time. IFRS 9, in which we'll provide more guidance at the half year, we would expect to have some impact, although probably not major. And again, I think we're sort of living in an interesting period, let's call it that. So having completed $3.5 billion of buybacks in the last 6 months, a good profit generation in the first quarter building the capital ratio, the guidance around how we deploy that capital remains consistent. It's about growing our business. You make a good point around our capacity to deploy all of that. It's very much about generating profits that supports the dividends. And we'll think about buybacks periodically, but we won't be revisiting this, at the very earliest, until the first half.
