Hi Michael, it's John Milligan. Your first question is just going to be segmented into higher risk HCV patients for treatment only, I think that's the way you phrased it and I would say, it's very difficult to characterize across the very different payor groups, who respond differently to the people, who of course are paying the premiums and so there is a wide range of behaviors that we are seeing out there. There are certainly some groups, are trying to segment more for the high risk nations, but of course some groups are more open ended as to what kind of patient can come on board. So you could be higher risk by a number of criteria including our physician judgment based on co-morbidities, you can get therapy based on other criteria. Interesting, if you look at for example Metacare [ph] patients, there have quite a range of patients, who were able to be treated under Medicare and CMS is sort of dictated currently that all patient should be allowed therapy. I think what you'll see overtime is, rather than a restriction more of a loosening of the guidelines over time much like we saw with HIV. I should think, guidelines that are loosening of the criteria for reimbursing which was just typically what happens overtime as more patients get treated, who are the worse end of this spectrum, there will be more capacity and more money that will be freed up to treat people, who are earlier on in their disease. We also think the eight week, the cheaper option is going to be very favorably looked up the payors as well. We think also that treating earlier is you best chance to save the most money for the healthcare system overtime and so we would encourage people to think about that way as well, so you will see some restrictions currently and I think for example in the Medicaid, which have fixed budget, so be greater restrictions than anywhere else, but I can't give you one answer, I just think it's an evolving feel, which will eventually allow most patients to be treated but I do think, they'll be a triage system set up over the coming years to the get to the right number of patients.
