Look, we feel -- Sara, we feel comfortable that we can maintain our industry-leading growth rate going forward. The -- our market opportunity, as we outlined during the prepared comments, we feel very good about. We think that this once in decade sort of technology shift that we're going through, driven by these new technologies, creates significant opportunity for us. And we continue to invest, as you know, substantially to capture those market opportunities. If you think about the opportunities that are available to us, there's sort of the new technologies, that's one axis on all of the work that we've talked about relative to social, mobile, analytics and cloud, so that's one growth vector. There's a second growth vector that relates to new geographies that we -- where we feel we're underpenetrated. So if you think about our geographic footprint, we think that there are still opportunities for us with -- in an earlier question I addressed the European opportunity. But we continue to believe that there are opportunities for us in other parts of the world and we're investing there. We've talked to you about the rest of the world -- we call the rest of the world, which is Asia, the Middle East. We made good -- some good strides, early strides but good strides in Latin America last year. So we think there's opportunity to grow from a geographical standpoint. And then, of course, when we look at the industries that we serve and new industries where we don't have a presence, we think that the opportunities there continue to be significant. The existing industries continue to represent good growth avenues for us. But then, we have new opportunities. For example, we touched briefly during the prepared comments on the public sector. Again, a place where we made good strides last year in 2013, and we expect to continue to grow in those -- in that industry as well or in that sector as well. So if you think about it, across 3 growth vectors, new geographies, the new technologies and new industries and new markets, we think there's still a lot of upside here. And since we're investing ahead of many of our competitors because of where we maintain our operating margins, we think we have an opportunity, and we'll continue to maintain industry-leading growth as we go into '14.
