Yes, I guess, the first thing on 2017, we hit the number, I think, we had $0.30, $0.35 in last year's waterfall and we came in on that number. This year, it's $0.50, as I mentioned as a result of the zero-based budgeting initiative that we've started. A good chunk of that is a result of some headcount actions that we've taken as we look to expand the layers in the organization across the organization. There's some other items around just managing indirect costs, which we are in the midst of. We've got a pretty robust process in place to make sure we hit that. So, we feel confident in our ability to hit that $0.50. But again, we'll help us fund some of the strategic investments. And we haven't had a chance to talk much about that, but it's investments and things that are important to drive growth and, for example, in our Supply Chain business, our visibility, and optimization tool, RyderShare, we're going to be spending a good amount of money on that this year. It's important for our contractual Supply Chain customers. And really, it's going to give us a competitive advantage, I think, against the other players in that space. So, these are investments that are important, important to our future growth. And this year is an important year to make that happen. So, we're going to be doing that, we're going also be spending money on more salespeople. So, to increase of the growth rate, we have added some salespeople, which are already paying dividends. So, we're investing in that. And then also investing in some other technology tools that will impact FMS and Dedicated, which you'll hear about here in the next several months.
