So SG&A certainly was higher this quarter than it would typically be. We talked a little last quarter that not only have we invested in headcount in Robert Half Technology, which is over-indexed to use your term, but we also began adding more broadly to our other divisions as well. We felt like, at the time, that things were getting more positive, the environment was getting more positive, so we began to add to headcount in the third quarter. We continued to add to headcount throughout the third quarter and into the early part of the fourth quarter. As we disclosed in our earlier remarks, we did add 8% to our overall headcount for the year, which is significantly faster than our revenues grew during the year. So in short, we were trying to get ahead of these positive trends. We clearly hired earlier than the revenues would otherwise dictate it. But frankly, the acceleration we saw in the fourth quarter, if anything, confirmed our belief that it was a good time to add to headcount broadly, not just limited to Robert Half Technology. As you then roll that into the first quarter, since most of the hiring took place at -- toward the back end of the third quarter and the front end of the fourth quarter, there's not much extra SG&A, if you will, that rolls into the first quarter. So our assumption would be, as a percent of revenue, that the first quarter, given the revenue guidance we gave, the first quarter SG&A percentage shouldn't be heavier than the fourth quarter, and if anything, will tick down a little bit.
Mark S. Marcon - Robert W. Baird & Co. Incorporated, Research Division: Great. And then just switching gears over to Protiviti. Can you just give a little more color with regards to the areas that you're seeing the strongest level of demand? Obviously, it's been terrific. Looks like you may have also taken pricing up, given the sequential trends in gross profit relative to revenue.
