Yeah Neil on the first one the major gating factor is the FTC process with 7-Eleven, so we're watching the process, we're contributing where we can as needed, but that's really a process between 7-Eleven and the FTC. What we know as of today it continues to go well and like I say, I use the word were targeting for the end of Q1 or we're hopeful that the end of Q1 is the right timing, but really the gating item is essentially that process that is not really our processes it's more 7-Eleven in the FTC. So we're supporting it where we can. As I mentioned in our prepared remarks, we responded to questions, we're supporting it as much as we can. The other activities that we have to get accomplished, which we're very confident we'll get done is the transition services. Obviously it's a major transaction between us and 7-Eleven and there are some services that Marathon is going to transition to 7-Eleven over time. So that's been a lot of the internal work that we've been doing recently. But the bottom line and I know everybody keeps asking about your use of proceeds, we're as anxious as anybody to get to that spot, but at the end of the day, the major gating item is we don't have control of that timing. All we can do is continue to give you the best insight we have and right now we still say we're hopeful its end of first quarter. We're targeting that. We think that's achievable based on what we know. So that our best guidance at this point. On your second issue, as far as the use of proceeds, we've tried as best we can to frame what we believe is the two main pillars that we're going to be targeting, which is getting the balance sheet back to where we want it to be and then return capital to our shareholders as quickly and as efficiently as we can and on the first issue, we've tried to make the statement that our debt situation majorities is there's about $2.5 billion the comes with your essentially minimal friction cost and we'll jump on that one right away. Right today, we have a little over $11 billion of debt. We'll continue to try and evaluate as everybody wants to know where is mid-cycle going to be etcetera, etcetera. We need to work with the agencies so our financial team, Mary Ann and Tom and the treasury team will work with the agencies as to the proper path to bring that debt down to a level that we think is the right spot. In an effort to try and give as much color as we can, we've kind of said to people that hey we don't see it going below $5 billion and that's kind of like our low refining case if you want to call that. So if you say in that regard, we have about a little over $11 billion. We don't see it going below $5 billion. So a number of the put on the piece of paper is around $6 billion depending on how well the recovery is and how quick the recovery is and working with the agencies etcetera. Absent that, we said we're going to return capital, we've talked about what's the best way to do that and the only reason we don't give additional color there is because at least in our mind, we believe right now is end of March is the targeted timeframe. So we have another 60 days to go and we'll continue to evaluate the market and the opportunities and we've been going through this internally with our board, with our advisors, with ourselves and we have a pretty good framework, but we just don't want to get ahead of ourselves in case it takes a little longer than we were expecting. So we do want to return that capital to shareholders. I personally am a believer that refining to a large extent is a return of capital business. We got to position ourselves where we're generating cash and then think about the best way to create value returning it to shareholders and we've talked about all the various ways to do that. It's predominately in a buyback type mode, that's what we're thinking about and then there's pros and cons to the various ways that you can do that and then our commitment is once we get close enough that we know we're there then we'll come on publicly and give a little bit more color as to how we think that'll affect itself, but our goal is as efficiently and as quickly and effectively as we can, we want to try and provide that return of capital.
