Well, I mean, look, Noah, we would certainly like to see some backlog start to build, obviously, as we introduce and get closer to the launches of things like Latitude and Longitude, we would expect to see some build in that area. We announced the new Sovereign relatively late in the year, obviously, and not in a great environment in terms of what was going on in the economy. But I would expect to see a start to build some order book of the new Sovereigns. But the bottom line is, I don't think people should be terribly surprised. I mean, the fourth quarter -- frankly, the second half of the year was not particularly strong in the business jet market. That being said, there's no reason to believe that there's going to be a -- that's not going to normalize and we're going to get back to sort of where we felt in the beginning part of 2012. With respect to production rates, again, we look at this on a very regular basis and anticipate what the order flow is going to look like based on what's going on with customer activity, and that is what is setting our production schedules as opposed to looking at backlog. This is a classic example. If you look into 2013, we're guiding to what we believe will be a modest increase in a number of jets. Obviously, that's based on what we see going on in the market, what our anticipation is in terms of order flow. It takes into consideration, though, as we set production rates, how many aircraft went from '12 to '13. As you know, we've been trying to make sure that we're forecasting this very accurately. There's no question that we would have expected higher sales in both the third and fourth quarter than what we actually saw and we've adjusted our production rates in 2013 accordingly. But we still believe, if you look at the market, you see what's going on with customer activity, where we believe the cycle is, that we still think it's appropriate to build towards a modest increase in deliveries in 2013.
