Yes. Look, on the 787, David, most of the inventory that we have is the result of the quality assessment that we've been doing and the rework associated with it. It's more heavily weighted there than it is customers not able to take the aircraft. So as I mentioned, we're going to have a big fourth quarter on deliveries here, and again, paced by our inspections and quality effort. And then that will pick up in '21. But as Dave said and I think I reiterated, that we're continuing to assess the wide-body market on a day-to-day basis and particularly linked to how we're seeing international coming back. So we're being, I think, very clear-eyed around who we've got in the backlog, the probability of delivery, the time frame, the potential movements of aircraft. And then where we've got unsold positions, what's the real probability there and risk assessing that. So that's going to continue to be our discipline, but we're, again, very diligently focused on it. And if we have to make further adjustments down, then we certainly will to match the demand. And maybe I'll just jump on the 37 and then hand it back to Dave. But look, on the profile around the 37s that we've got parked, really, 3 major kind of, I'd say, kind of ways we look at it. Obviously, you've seen the cancellations and contractual changes, and sometimes, those contractual changes are recontracting the airplanes to move out to further time frames. We're assessing the financial conditions of every customer and assessing that health, and then just other, I'll say, potential delivery risks, which is really tied to the recovery and the challenges across the globe with the pandemic. So all those taken into account, we go through a pretty thorough risk assessment over that profile, including, obviously, day-to-day contact with our customers and their ability to take the aircraft in certain time frames. But look, I'll tell you, it's dynamic. It moves around. We've got a team that's dedicated to that skyline and engaging with those customers, and we're making adjustments real time. But at the same time, doing our own risk assessment. And that is a clear eye towards liquidity. If we see more risk, how do we bolster our liquidity? If that risk does not materialize, then it's upside for us. But we're doing that to really kind of understand, I'll say, the band of risk from the baseline plan that we have in place. I don't know, Dave, if you had anything you want to add.
