Yes. Rick, I'd say I'm never quite as satisfied as I'd like to be. That's for sure. What -- we've learned a couple of things. I think of the 7 or 8 years we've now been fundamentally focused on emerging markets and their growing economies and so forth, I'd say, if anything was underestimated, it was the degree of volatility of currency, which is also heavily driven by the strength of the U.S. dollar. And while we can't predict those things, since this business is 100% in emerging markets, that's always a bit of a challenge. Now that said, the underlying growth in those markets has been steadily strong. And it's interesting. One indicator of the attractiveness for those markets is, let's just say, the multiples and prices and so forth that anybody who owns a pharmaceutical business in those markets thinks that the company is worth. And as we track those for a long time, they're probably some of the highest multiples in the world than any business -- the businesses that make money. They're attractive. The markets are attractive. The attractive parts of branded, generic pharmaceutical worldwide, they're the most profitable. They're very profitable markets for good branded products as compared to Europe or the U.S. or something like that if you're in that business. So we targeted this business for a reason. There's underlying real growth. Brands matter. Quality matters. Breadth matters. And it's kind of all the fundamentals that we think are stable, durable, attractive, et cetera. And frankly, all those economies have progressed as we would like, maybe not as stably and maybe not as strongly, in some cases, but the growth there is still strong.
Our own challenge is the R&D investments, to continue to expand product lines and product depth into the markets. We keep our R&D somewhat decentralized by region. India has its own, Latin America has its own, et cetera. We're always looking for greater and greater productivity and greater and greater launch activity out of our teams. Every now and then, we're going to run into an Argentina, a Venezuela or a tax issue in a country, like we did in India a couple of years ago, et cetera that are going to put a dent in the growth rate for a given year, and we've seen that. But the underlying fundamentals are quite strong, quite good. And we keep plugging away at all the fundamentals that we know how to manage. And as you can tell, this last year, we've had steady sequential improvement in our performance, excluding exchange. And they're up at 8%. I think that's pretty good. That means that we know how to take the corrective actions to get stronger, to get better, to drive the business better. And I think the fact that the managers of pharmaceutical business are up to an 8% growth rate and looking forward to even improvement in that -- I think that's pretty strong. So yes, we like the business.
