Larry, it's Dave. So I guess I want to be clear in terms of your comment on -- or question around partnerships. Allison has been fortunate over the years to have partnerships at multiple levels. As we think about our strategic relationships, whatever term you want to use, and I would say, the team here certainly, despite some pretty challenging conditions over the last few years, has really invested a lot of time and effort supporting our customers, frankly, as well as our suppliers. So I think we feel well placed in that regard. There are always opportunities to work together. Frankly, I think the amount of interaction that we've had for a lot of different reasons over that period of time has served both parties' interest. So as we sit today, frankly, we think more broadly about that than we did several years ago. So to your question there more directly, we don't rule anything out. I think we have a tremendous amount of optionality around how we think about our different end markets, what the future holds. We've also maintained a fairly high level of optionality with our financial capability over the years to be at some level, opportunistic at the same time, be supportive along the way of various situations. So I think the growth initiatives, as we refer to them, will require a fairly heavy level of interaction. And I would say throughout, whether it's customers, suppliers, other technology relationships as well have continued to serve us reasonably well the last couple of years, and I would expect more of that here going forward. To your R&D question in terms of cadence, I'll go back to -- we invest in R&D based on opportunity sets, as we see our opportunities, they're relatively high right now. The amount of announcements that you've certainly heard from Allison over the last few years really supports that point, which is we're spending for good reasons. It's really very much market-driven to the extent that there are opportunities there, will continue -- our plan is to continue to invest at the same time. We've had experience in prior years, prior cycles with some level of adjustment in the market. The team here is well heeled in that thought process, and we'll certainly adjust accordingly. So I wouldn't say anything at this stage, is absolute with our business, and we'll take appropriate actions to mitigate and manage towards whatever those market conditions are. But I think the big takeaway here is maintaining a very high level of optionality, as we think about our business and our end markets going forward.
