Myles, I would say -- first off, to take a look at NMA, we are still working through that same disciplined decision process that we talked about previously. We’re making progress on that. We had very productive conversations with customers. We understand the markets. It's clear that there is a market need, but we’re working through the details of the business case. And as we said, we are going to be very disciplined on how we do that. And while we’re making progress, we're not up to our decision point yet. And just to provide clarity on that, as we mentioned before, we do see a decision point this year and that is a decision of whether we would offer the airplane in the market. And we need to complete the business case analysis before we arrive at that decision, but that is one that’s for this year. And then assuming a positive market response or depending on the market response, we will make the final launch decision next year. So it's a two-step decision process as we've always done with Commercial Airplanes and a very disciplined process. All of that, we're continuing to work our development program work and maturing the technologies, reducing risk in parallel to protect a 2025 EIS or Entry Into Service. We think that remains important to our customers. So we’re working all of that in parallel. And again will March in a disciplined way through our decision process. Our assessment of the market and the size of that market hasn’t changed. Now, to our broader question on orders and how the markets looking, again, we continue to see strong demand signal. So I think you see that reflected in orders volume for this past year with 806 deliveries and 893 orders. And, while as I said, we expect some moderation or timing on orders going forward, we have a very robust backlog position with about seven years of backlog -- equipment backlog in position now. If you look at the stats on traffic growth, Cargo, global expansion of route structures all the fundamentals remained very strong, and we’re encouraged by that. So we expect to see continuing steady orders volume. I wouldn't expect that to change significantly depending on the NMA decision. So we’re going to be in the marketplace continuing to compete and win. I guess one other reminder on NMA, if we do decide to proceed with the authority to offer -- don't expect a big change in the R&D profile. This is all part of our planned R&D profile. As Greg said earlier, we expect R&D to continue to be roughly the same in terms of percentage of revenue going forward. So as revenue grows, you will see some R&D growth. That will be at the same percent. And if we launch NMA, it will better end on the backside of 777X. So from a profile standpoint it fits very nicely. Greg anything, do you want to add on that?
