Yes, so very good question Shahriar. Thanks for asking that. So look, I think we are patient. We believe that getting our debt down to the 2.5 times net debt to EBITDA range this year is very important. And then I think also giving clarity to that long-term capital allocation plan, putting another year behind us and showing that we can meet or exceed our expectations, I think is also helpful. That's helpful to the agencies as well. I think one of the things they'd like to see is whether we can withstand the business cycles, including things like what's going on with coronavirus right now, which I think in 2020 we're going to have a very good year despite what could be, symptoms of a recession off of that, off the coronavirus. So I think we're very strong company, I think we’ll show that in 2020, but I think it's very important, for us to do that. Now, in terms of the direct question about, strategic options, I think we'll be patient through 2020 and into 2021 to see that play out. But I can also assure you that, the Board continually thinks about what's the best way to unlock value. You know that I spent a lot of time in private equity. And for me, the only difference between being a public company and a private company, is that every day I wake up I get a scorecard. I get my report card, it's in the form of our stock price. And from a private equity standpoint, they market on a quarterly basis, but I can assure you that most of those companies are marking their quarterly mark of their value based on what the public markets are creating at. And frankly at the end of the day, you unlock value the same way in both private and public market settings. You either do it over the long run or you do it at particularly with the private equity firms, you look for an exit, and the exit is limited. You know this right now, there's many private equity firms that would love to exit their generation, but there is no exit for them. And if they try to exit into the public markets, they have too much leverage and they don't have an integrated business model, which is what it takes to compete in the public markets. So, we think we can unlock this value in a public market setting it just may take a longer period of time. And we've got to be patient to do that, but I don't see that if there some silver bullet by becoming a private company that all of a sudden there's going to be this huge value uplift, because you've monetized the value of a company the same way whether you're public or private.
