I'm happy to do that Keith. Let me -- I'll start with a little bit of context around the quarter, then, Christa, maybe, you could just drive in, give us specifics. First of all, overall, as we said, Keith, we're driving toward a commitment around a 25% margin with a detailed game plan in place to do that. That's fully on track. Everything is moving as expected. Q2, from our view, actually did nothing to change the view on that. I can see where you're coming from, as you look at the results. But as we look at behind the results and the overall game plan, as Christa described, 5 very specific elements are going to drive progress there and get us to that 25% margin. Three are in our control around restructuring, revenue engine, Aon Broking, those are progressing very, very well. We saw great progress in the quarter. Two outside of our control in interest rates in pricing and GDP growth. And we said all along, by the way, in addition to getting the 25% margin, we are going to simultaneously invest heavily in the business, which we continue to do in multiple places. That means, we're going to have, really from our standpoint, look at this year-to-year not quarter-to-quarter. And if you look at it year-to-year, as you know well, our record reflects reasonable progress. When you think about 2005 to 2010, we've increased margin 530 basis points, give or take. That's roughly a little over 100 basis points a year from 15.1 to 20.4, while simultaneously making all the investments that we've described before back into the business, fighting the headwind on pricing and rates and the economy, et cetera. So from our standpoint, we actually feel good, very good, about being on track for the 25%. Literally, nothing has changed in our mind in the context of that. And maybe Christa could describe, kind of, the quarter specifically. But overall, we feel very good about it. And importantly, to your question, really implied what's around do we have economic leverage to a changing economy? And we absolutely believe we do that, and again, nothing in the quarter in our mind changed that. But, Christa, maybe you can talk specifically about the quarter.
