I'll take the benefit side, and I'll let Susan discuss the margin side. On the benefits, we -- as I mentioned, we have really been thoughtful around how do we adjust the benefits appropriately considering the funding that's in the marketplace and as a result of the reduction and -- from the latest rate notice. And so we've tried to really do a significant amount of research around where are the priorities for the Medicare beneficiaries and what do they value most by particular segments, whether that's in the military, whether that's duals, whether that's agents, et cetera. And we feel really good about that research and feel that we are going to come out with a value proposition that is going to meet the mark for each of those segments, considering the funding side. And as you can see in our commentary, we made a comment about that we did increase premium plans this year and coverage more. We felt that that was a really important benefit that people are looking for. And in addition, in our duals population, we continue to ensure that we are providing the ample amount of support for supplemental benefits, because we do find that lifestyle is an important part of them to continue to improve their health outcomes. Relative to our competitors, we've gotten an early view on it. It's always the most positive view, and we feel we're in a good position. And I just want to remind everyone, last year, we weren't the cheapest in every market. What we find with our brand, our relationships with our brokers, our quality scores, our experience, and our Star scores specifically, we find that we compete when we are within shouting distance between the various different plans. So, we don't have to lead the industry in every benefit. We have to be close. And what we see when we do that as a result of our stability of our platform that we are able to take a significant amount of the market share there. So, benefits are important, but I would just emphasize, we've never pride ourselves on being the cheapest. We want to be in the range where it's competitive and people are having to make a decision between a few plans, but we always went out a result of the quality and the ability to service our members.
