So, Mark, this is Joe. Relative to headcount, we, pretty much over time, have demonstrated that we map our headcount what the market conditions warrant. And typically, during the more opportunistic times in the cycle, you’ll see us adding headcounts or when KPIs are looking strong and then when the economy becomes more challenging, I think our history shows we have a discipline of aligning headcount. Fortunately, we have -- over 40% of our total headcount is in newer associates so there is opportunity to ramp those people up. Most of our 4-plus-year population, they're performing at very high levels, so we don't have a lot of capacity with those individuals, even given our infrastructure. The nice thing is that if the economy were to flip, natural attrition really takes of care of the bulk of alignment of headcount as it becomes much more challenging for those new associates to be productive. So that kind of almost, to some extent, really takes care of itself. And we saw that the last downturn where we were able to hold to the majority of 2-plus-year people, and the majority of our attrition people came with less than one year or less than 2 year people. So I would say that's what you could expect from us. We do feel optimistic relative to what the market demand conditions are. We've seen our KPIs, especially here over the last 3 to 4 weeks eclipsing 13-week averages. So while we increased some of our headcount in Q3 with a little bit greater rate than year-over-year, revenue is growing, we anticipate to selectively continue to invest in markets where we're experiencing growth. What that will mean from a margin standpoint is we've been realigning our fixed infrastructure cost associated with the transition services agreement which we're supporting related to our KCR business, which departed from Kforce earlier in the year. I think our team has done a nice job on that. And we believe, at this point of time, that we have a fixed infrastructure which is inclusive of personnel, NCs that can support a much larger revenue base. So that's where we'll obtain quite a bit of our operation margin as we look out to the future, as we layer on more revenues on top of that fixed operating platform.
Mark S. Marcon - Robert W. Baird & Co. Incorporated, Research Division: And just a follow-up on that, what percentage of the positions are now being filled by the NRC and were you anticipating future adds being in the NRC or in the field level?
