Certainly. As you mentioned, we always strive to be ahead of the innovation curve, and that goes to the core of our competitiveness as a global firm. Whether it's in the rail transit business or in the aerospace business, we're constantly thinking about the next products we should put in the marketplace that will make sure the company is always at the forefront of what customers need.
I mentioned in some of my comments the intensity of the research and development investments we're doing now. There was a lull for a few years because a few years ago the priority was to put the company back onto a solid financial footing, but in the last three to four years we have been working on six new aircraft development programs on the aerospace side. That's a lot to take on.
In the investment community, people will wonder whether our risks are adequately managed. We feel very confident that even in this current economic downturn, we have to make those long-term investments. We're talking about the CSeries, the global aircraft manufactured in your riding. We have two new programs on the go, the Global 7000 and the Global 8000, new Learjet aircraft, and the same on the rail side. We constantly try to position ourselves ahead of the curve.
