Sure. Akash, I'll maybe start with the last question and move forward. So we outlined earlier, right, we're looking at our 2020 spend plan. When we're talking about our $150 million of savings, we're looking at our original 2020 spend plan, which as I mentioned earlier, aligns roughly with 2020 sell side consensus from earlier in the year and that's where the $150 million of savings are identified. But as you can imagine, you know the trajectory of spend with both external spend and a lower number of head count and fewer additions to our infrastructure, those savings are going to yield over time, if you're looking at a five-year revenue model plus a five-year expense model. And so that $150 million, while not necessarily repeated every year because we're going to have additional spend as we grow the business from this adjusted baseline, but we're adjusting the baseline of our costs and our cost growth to make sure that we can commit to long-term profitability. And importantly, I think expanding profitability as we look at adding to the topline with the likes of VUMERITY and 3831 and additional growth on ARISTADA and VIVITROL. Turning to our long-range expectations for ARISTADA and VIVITROL, I mean, I think obviously as we - as we look at were at 2019 and where we exit 2019, we'll make adjustments there, but I think our overall expectations for both products, we remain optimistic. We'll guide in 2020 to a logical extension of our existing growth rates. But long-term, I don't think we've lost our potential view that both of these products can be very, very important ones. Certainly with VIVITROL, as Rich mentioned earlier, right now around average market penetration of 5% across the country, and in certain states over 10%. We think as the treatment paradigm changes, there is long-term growth opportunities for VIVITROL that can be - that can change the trajectory of that product really at any time depending on state by state changes. And then with ARISTADA, I don't think we fully understood and realized the value of the product with our ALPINE data and our focus on hospital starts and we're going to continue to work on changing that growth trajectory as we move forward. And then the last one was overall profit margins. I mean I think, overall for the business, yes, our margins are increasing, especially I think with the addition of new revenues from VUMERITY and 3831 and - but more specific adjustments now in the long-term model, I think we'll leave to another day as we see what those growth trajectories actually are into 2020.
