So I'll let Tom talk a little bit about kind of the financing of it, I would say this, Brian, just to give you a little context. We have a lot of markets, where we have physicians who use our facilities today, who have additional cases, they would bring with the appropriate technology, often robots, and we look at each of those markets, you know, independently to decide if it's the right investment to earn that business. And we're finding more and more markets where that make sense. It's high acuity business, its new business; it's able to be done in our facility safely. And so it's about existing docs also, expanding their business, it's also a way to open our doors to procedures in a book of business that we just didn't have the opportunity to get in prior times. And so we're working closely with managed care companies and our partners at health plans, working closely with the local markets, to ensure that it's accretive. But ultimately, we see real opportunity to grow acuity, earn business, move it from a higher cost setting to a lower cost setting. And actually, you know, a lot of winners there. The healthiest is the winner, the patients, given our patient experience scores are winners, the physicians like it. And so market by market, we're making those investments you've seen this year, it's been a pretty dramatic increase there. And we actually do see big books of business when you think about how physicians are trained, big books of business, in ortho and spine that are growing, but also when you think about Da Vinci, it's general surgery, it's basic GYN. And so we're going to be aggressive and finding ways to compete for that business and provide the value we can uniquely. So I don't know Tom, if you want to talk a little bit about the investment profile.
