“Right now, we plan for, obviously, not to be quite what it was in 2023.”

In context

“that productivity will be not only what volume might look like. I can't say a lot about that now. But also, we don't have this resource with the shadow factories. So, we won't quantify it specifically, but it is an important component as we think about going from what our profitability has looked like at BCA historically and where we think we can get to. Dave Calhoun: Maybe I'll just add and refresh everybody's memory because we've talked about it a couple of times. In our shadow factories, we put more hours into those airplanes than we do to produce it in the first place. So, anyway, that's a metric I know everybody understands. Seth Seifman: Great. And maybe if I could sneak in one more to -- the advances, it was a nice tailwind in 2023. How do you think about that in 2024? Brian West: Right now, we plan for, obviously, not to be quite what it was in 2023. That's factored into my comments. The good news is, is that we still have a pretty robust demand environment. Our commercial teams are working hard to chase every next order. So, we're not counting on a big one, but we know that our teams can go win campaigns. Seth Seifman: Thanks very much. Operator: Thank you. The next question is from Jason Gursky from Citi. Please go ahead. Jason Gursky: Hey, good morning everybody. Brian, just maybe a quick clarification or maybe, Dave, and then a question on defense. The clarification on the rate 38 a month, you guys still firing some blanks so that the number that you're actually producing is a little bit less than that? Just kind of curious what rate 38 means. And then on defense, Brian, you've historically broken things down into that 60, 25, 15”
