Yes. So, thanks, Bill. The first part of your question has to do with transparency and surprise bills and pushback from providers, about that, and its complex, as you know. But going back to my prepared remarks, we believe, if you just look at the value proposition we bring into marketplace, we'd like to get more and more exposure to the prices that are out there for us.Because as I said, with the full confidence, we believe, we're the best deal in town. And so, making sure consumers see that, making sure physicians see that, making sure that plans are working with us to move more of their laboratory services to a great value provider like Quest Diagnostics is what the strategy is all about.And so, the more visibility of that is a good thing for us. And we're doing this with the plans and the preferred lab network is part of that. We're also doing this with employers with the plans, because as those employers look at their employee cost of healthcare, they're looking at what they can do to help their employees out and we believe our category is a good example of where they can do that. But if they do it for us, they could do it also with other healthcare services like radiology and physical therapy. So, we think it's a good opportunity for us.And then, finally, you asked the question about preferred lab network. We continue to work with other partners. We have the nationals, but we also have a number of regionals. And as you know, we enjoy a large presence in Florida. If you look at Florida Blue Cross Blue Shield, even though they haven't announced a preferred lab network, we are very strong in Florida and we have a great relationship with them.So in essence, you could say they are our preferred labs, even though we haven't announced it. So as we work through where we go with this long-term, you'll see what others are willing to provide publicly. But this will continue to be a trend that we'll keep on working. Mark?
