Yes, Phil, the – obviously -- there's obviously severance costs here in terms of where we have duplicate labor and other savings. There is obviously fees and associated with that. But once we get through this year, and get through those costs, I think we're focused really on what our cost structure will look like. So maybe just to give a bit of an update on that, I want to be clear about that. The integration is going well. That's on the system side, the organization side. And we're -- we do have line of sight to exceed our targeted $500 million costs in capital savings we announced at the time of the transaction. So if you remember that $500 million was made up of $350 million of operating cost savings, and $150 million of capital reductions and those really came across three areas. The direct savings from the transaction, restructuring our corporate staff groups to better align with our new portfolio on the ConocoPhillips side. And then stopping our new ventures exploration program, that reduced our targeted exploration spend from $300 million to $150 million a year. And in fact, our 2021 capital program of $5.5 billion reflects a reduced exploration capital spend along those lines. Now, our expected operating cost savings have now increased from $350 million to $600 million. So our teams have really done an excellent job turning over every stone both in relation to the transaction, and restructuring our center. So in total, the operating costs and capital reductions will now amount to $750 million. So we're up from $500 million to $750 million and we're still counting. I think, as Matt mentioned, we still have the opportunity for costs and capital efficiencies across our D&C spend, supply chain economies of scale, and also improved price realizations on the commercial and marketing side. So we do expect that $750 million to increase through the year, and we'll be providing another update on that in March. Now finally, just to tie back to Ryan's prepared remarks, with the operating cost savings having increased to $600 million, together with the $400 million of sustainable cost reductions, each company made, both companies made together in 2020, we anticipate our 2022 operating costs to be around $6 billion. And that's $1 billion less than our pro forma costs in 2019. And that was really the last normal year pre-pandemic. So it represents the best baseline, that's all assuming production flat at about 1.5 million barrels a day. So at the end of the day, as we think about -- we get through these transition costs this year, we then get into a run rate of about $6 billion, it's those bottom line costs that matter at the end of the day. And that's what we're very focused on to make really the company, the strongest competitor in the business from two already very strong companies.
