Yes. I think that I -- in looking at the increased cost for the regulatory initiatives and compliance initiatives, that we did see the ramp. And that came in the form both of additional personnel, so you saw that through the comp and ben line, particularly in this quarter. I -- and then also through outside services, which increased 9% this quarter year-over-year. And I think, going forward, I -- as I mentioned in the prepared remarks there, we continue to have a number of these initiatives that we're working on, albeit that the portfolio mix changes as we go forward. So for example, things like CCAR, we definitely had a big step-up this year and, as a result, had to bolster our teams but also to use outside consultants in order to help us get to what we thought was the appropriate level for the 2014 capital plan. As we move forward into 2014 and prepare for our 2015 capital plan, we're going to continue to make improvements on that front, but the incremental increase won't be as much. And I would expect that the use of outside consultants to help us get there will also be lower. So you have things like that where the trajectory, I would expect, would go down. At the same time, we have initiatives like AIFMD over in Europe where we did incur expenses in 2013 and again particularly in the second half, but I would say, in 2014, the costs related to that will go up relative to 2013. Now in certain situations, like in AIFMD, that's a new service that we're also providing to our clients, so there are revenues that come along with the incremental costs. So I take all of that together from an expense perspective, what we're looking at is that the expense levels we experienced in 2013, relative to these risks and regulatory initiatives, will be approximately the same, albeit that the mix between what I'll call the permanent costs will go up a little bit from where we are now, where I would expect from the outside costs to begin to come down.
Luke Montgomery - Sanford C. Bernstein & Co., LLC., Research Division: That's helpful. And then just more broadly, would you agree that some of the difficulty with operating leverage over the last few years is that you've been adding clients and mandates and, with that, I think, more support costs, while relationship revenues have obviously been falling? I guess I'm aiming at whether you've attempted to isolate the impact of organic growth on your expense and margin trends.
