Let me take a stab at it and then LeAnne will correct me if I get it wrong. The legislation required, of course, if they get the bundle going. As part of getting the bundle going, they had to make some guess, some estimate of who is going to opt in 100% and who is going to transition in gradually. And then, the way they were thinking about it is that, "Okay, if the guess is wrong, we'll get all the answers to some people. We'll implement the bundle. And then, a year later, we'll take a look and make an adjustment if appropriate." And it has turned out, it appears, that their answer, their guess is way, way off. And so our argument is that, we were thinking about it in a sense of a way, if your guess was close, but you're way, way, way off, not because you were foolish, at all, it's just the way life has evolved. And therefore, we want you to change your plans and do it very quickly. And some of them are saying that the way the language is written, they don't -- some of them are saying they can't, some are saying they don't have to, and they just assume weight anyway. Now LeAnne, why don't you amend if appropriate.
