Yes. Sure. So, maybe I'll take the second question first. And then Mark if you would take the first question. So, with respect to the -- your question, the way that we're thinking about the future is I think as both Rick and Mark highlighted is COVID-19 this pandemic that we're all living with no one is working like they did before COVID. And I think we would expect that like perhaps many of you that COVID will continue to have an impact. I think like many of you though we're also expecting that we've all gotten a little bit smarter about how to adapt to this pandemic. And what's safe, what are safety protocols, and what are safe activities to pursue and which ones aren't. And so I think we're all smarter about those kinds of things. So I think that as we think about the future, we think there's certainly a degree of uncertainty about the future, but as 2021 unfolds and I think you've heard Mark refer to when conditions improve, this is really going to be a very strong recovery story, because the early indications from physicians, our health care providers that are prescribing our product is it's easy to use, easy to get approved by payers. The efficacy that they're seeing is, as I think both Mark and I highlighted, as good or better often than they expected. And of course, some of the things that we've been talking about for years, it's oral, it's once daily, it's non-statin, and it doesn't have the muscle aches and pains associated with -- frequently associated with statins. So, all of those things are coming into reality. And as the effects of the pandemic dissipate, and I think it's reasonable to expect some time in 2020 when they will, then this is really a strong recovery. Patients will start to go back to their physicians. They will as we've been saying pay attention to their cardiovascular health, which they're not doing as much today. I think you heard Mark say that when you look at script volumes for -- new script volumes for statins even they're down 30%, 30% since the beginning of the year. If you look at PCSK9 volumes, they're down 40% since pre-COVID. So obviously a lot of folks are practicing medical distancing in this area, but it also implies that as this dissipates, it's an incredibly strong recovery as patients and their physicians return to addressing their cardiovascular health. So with that, I'll turn it Mark to you to answer the first question.
