Mike, it's Eric. Let me start on that one because the nature of our business has actually become, in terms of expenses, more fixed than variable and partly that is, as we automate, as we put more capital work and labor and we need to make that shift be even more dramatic to be honest and, I think, as Ron describes, we feel good about some of the investments we've made in some of the automation, but I don't think we've sufficiently adjusted the stack of labor that we have against it, but our business is actually becoming more fixed than variable over time. And I think that means two things. I think that means from an expense program and programmatic standpoint, we need to find ways to take out step level, kind of step function expenses off of -- out of our expense base, so as we automate we need to take labor out, as we work with vendors, we need to find ways to adjust downwards, as we get larger and they get larger and we force the scale benefits to accrue to both parties. So that's part of what we just need to do because of the nature of how this business has evolved, relative to where it was as a highly manual, highly variable business, 10, 20, 30 years ago. I think the second perspective that we've developed as a senior team here is because it's more fixed than variable, we actually need to find ways that in good times, we create more margin expansion and more leverage because in truth, while we have an ability to take some step wise and step function reductions in the expenses, in difficult times, it's hard to adjust the level that we would like, given that revenues could move as much as they are moving up or down. And so I think our historic belief that we should run with operating leverage of maybe a point in good times, I think that's not really something that makes sense as we step back and think about how this business has been operated, it may have made sense in the past, but that's something that we need to change. And so we first need to work through this particular market environment, but that gives you at least some context as to how we're thinking about this going forward as well.
