Okay. Well, first of all, we continue to believe that [ADAS] is an attractive long-term opportunity for us because it has the possibility of getting digital maps into more cars for uses other than navigation. You are correct. We have also noted that there appear to be number, perhaps more than the normal, of articles and even commercials that deal with the subject and are somewhat, if you will, teasing the public about what the possibilities are. Because this is part of the automotive industry, keep in mind that this kind of technology use is going to be adapted over a long period of time. This isn't something that's going to pop in the market anytime soon. We're very pleased, we already have a major customer which is using our digital maps for [ADAS] applications and we expect more to follow over the next two, three, four years. But this is going to be a long timeline. And yet an attractive one, because we think the types of applications that they're thinking about, a number of those applications are better informed with maps. Maps are not the only sensor or source of additional information or data that could impact an ADAS application, it could be radar, it could be other kinds of technologies. But when it comes to digital maps, things like lane departure, things like curb warning, adaptive cruise control, adaptive front lighting, adaptive transmission are examples where, in the R&D work that we've been working on for many years, we think there's a good body of evidence that suggests that this is a direction that the car OEMs want to go in. Once again, what comforts us and we get excited about is the fact that this is a different use of digital maps. It is addressing and helping the car companies to address a very real need to put more technology into the automobiles to reduce fatalities. I think that fundamental drive is not going to go away anytime soon. So we're going to continue to work and invest on this. I think the last aspect of your question had to do with building the data sets. And obviously, since we've been working on this for well over ten years I would guess, as we are creating each year's plan in terms of what we want to do with the database, we're taking into account the long-term needs from potential ADAS applications and incorporating those requirements into our map collection and building efforts. So, it's part of our long-term roadmap.
