Yeah. Thanks, Vijay, and hope you're doing well. So generally speaking, I'd say we're taking a similar approach entering the fourth quarter, as we did when we entered the third quarter. We've looked at order trends. We've looked at our backlog, which has grown versus when we entered the third quarter, and we feel very comfortable with our guide, and I'll kind of break it down non-COVID versus COVID. So non-COVID, we are seeing the market improve, but the exit rates are not quite as fast as they accelerated at the end of the second quarter. However, if they continue, we think we'll be at the high end. And if they don't continue or if something happens, they'll be at the low end. It's also worth noting, Vijay, that in the fourth quarter of 2019, we had two very material product lines growth for us. Cannabis was quite substantial in the fourth quarter. We're assuming no cannabis revenue in the fourth quarter of 2020, as well as informatics was substantial in the fourth quarter last year. So if you exclude those two, we think we'd probably be better by three points. So instead of down 4% to 6%, we'd probably be down 1% to 3%. So DAS came in minus 3% in the third quarter. It will probably be in the same vicinity due to those comps. However, if you exclude those comps, DAS would be positive in the fourth quarter. And then Diagnostics ex-COVID revenue was down 11% or 12%. And we've seen it start an uptick over the last few months. And so we are assuming that, that will be down high single digits. So that kind of explains non-COVID. It is closer to low - minus low single digits, but we have those two comps. From a COVID standpoint, you asked the question specifically on California. Yes, it is in the number at about $50 million to $75 million. The way we derived the $350 million to $450 million is the base business was $288 million in the third quarter. We're assuming the base business is mostly in that range, call it $250 million to $300 million, and then we're adding an extra $50 million to $75 million for each of the California labs and the UK labs, which overall gets you to the $350 million to $450 million. I think all of this is worth noting that none of this assumes any significant block down, obviously, COVID positivity rates are going up across the world. And right now, we are not planning on any significant lockdowns in any of this guidance. Should they happen, it could have material upside to our COVID revenue and material downside to our non-COVID revenue. But in general, that's how we kind of thought about the guidance, Vijay.
