Sure, Carter. So, as you know, we decided to get into that training business several years ago, we felt that was a very important part of sort of the service aftermarket element of our business and we weren't really participating in that. We had a lot of feedback from customers that they would be interested in us participate in that space. And so, as you know, we made a couple of fairly small acquisitions. Obviously, over the last few years, we've invested a fair bit in both IRAD and R&D, as well as CapEx to start to build out that training capability. The business is going very well, great customer feedback. I think the training materials and the techniques that we were deploying were working. The challenge was that, the time frame of how long that would take to build out the number of training centers and number of locations, it was a fairly daunting task and was going to take quite some period of time to do that. We happen to engage in discussions with Flightsafety, whom we had relationship for many years, obviously, in the training side. And so, look, we ought to link together, let's take the technology and a lot of the Tools and the capability that we developed organically and put these businesses together in a joint venture, and basically what that's allowing us to do is, take what we think were the advantages of that business and the positive feedback we are getting from customers and expand it much more rapidly. So this now has the ability to much more quickly accelerate the returns for us, and I think for the customers it sort of taking the best of whole worlds. The combination of what we would invest in organically and the significant footprint that Flightsafety has around the world, so that we could touch more customers in a time frame. It was much shorter than doing this just going training center by training center in terms of us putting more and more capital out there and Flightsafety already have the capital out there. So, as we said, the gain is a function of having invested in that business and having put those assets in the joint venture. You got to look at sort of reevaluating those assets and, obviously, we created a very valuable business. And so that's a good thing. I think more importantly, what we will see going forward is the earnings as a result of our share of that joint venture, which is going to grow much faster than we had, we stayed just on a pure organic path. And you'll see those earnings come through systems as we go forward.
