Yes. So what, so if you look at our current fleet, it's about $1.5 billion and we should do probably about, $290 million, $300 million of EBITDA this year, which is below our target and I had mentioned the impact of COVID on that is sort of right in that range of $50 million to $60 million impact this year. So we see that returning to more normal. We actually had an EBITDA, pre-COVID that was going up in the high 20%, 28%, 29%, 30%, but we're saying, okay, next year we think the airlines that we've backed are survivors, and we will see a return to a 25% of EBITDA margin based on analysis of our portfolio. And we do have a good chunk of assets in the freight market, which is doing really well and will continue to do well and we've added customers like Air France and a couple of other sovereign airlines. So we feel pretty good about 25% on $1.5 billion, so that's the $375 million. Then, turning to this, the incremental investment, we have $200 million of capital under LOI to invest in about 70 engines, all CFM 56 engines. So that's what we've been talking about and what we've been targeting. And the attractive, the pricing on it is very attractive, because there are few competitors with capital that are looking to buy assets right now. So we're able to get very good pricing. It's about $3 million per engine on average. We have some engines that we're buying is actually as cheap as $1 million dollars. So there's a bit of a range, but on $3 million of average for a CFM 56 we believe we will generate within our assumption on utilization for that is approximately 75% and I think that could end up and I think that's a reasonable assumption, it could be, there could be some upside there because I think as I mentioned, there's likely to be a tight market. But 75% utilization generates a 35% EBITDA margin on that $200 million. So that's an incremental 70 million. So if you take $375 million and add $70 million, the 450 number for approximately 450 per annum EBITDA for us for 2021, that's without adding any incremental benefits in the Lockheed Martin partnership, which I mentioned, which we believe will approximately $100 million.
