Let me start. John, you answer as well. Let's be clear. I think in any business like ours, you got a little bit of both going on. For example, we are investing against the emerging market consumer businesses because we expect them to grow. And at the same time, we've also demonstrated operating leverage which just is exactly to your point, which is having made the investments to start with. From here on, we expect them to self-fund a lot of the growth that's going to come from there. That's an example. We then go to our next business, which is the U.S. consumer business. We talked about investing in that. A lot of what we had to do is normalize some of the marketing spend in cards and as well, for that matter, in the consumer business, normalize marketing spend around the world. We've done that and we expect to see operating leverage coming out of that business as well. That's investment, but investment in a way that we think generates the operating leverage. Then you go to GTS. We've talked about that as well. There, we expect operating leverage sometime this year, middle of -- middle-ish of this year, something of that sort. And then you really get to the Securities and Banking business, which we've talked about before. That is a business which has been impacted by a combination of regulation, market uncertainty, volumes, a variety of different things. And that's a business where we are doing a little bit of both again. And by that, I mean that in certain of our local market foreign exchange businesses, local market consumer businesses -- not consumer, of trading businesses, there are some tweaking required in terms of investment. But by and large, there are large amount of businesses where we have reduced the amount of resources and hence the restructuring charge. So that's sort of the full picture of what's going on. I think John also stated that $3.9 billion may have been the investment number last year, but that's not the number next year. It's not going to be 0, but it's not going to be $3.9 billion And again, geared towards this kind of operating leverage momentum that we've started creating and plan to create going forward. Now that's to us the pattern of our investment and disinvestment, and it's consistent with where we think growth and earnings are going to come from going forward. John, you want to add to that?
