Yes. I think there's a standard basic level of certification you need for your product to qualify it for sale within the marketplace, such as electrical certification and safety certifications. That stuff is fairly universal. Of course, when it comes to street lights, as you mentioned, as street lights become more complicated with regard to different types of communication protocols and to different applications within the context of the smart city, the smart grid, the specifications and their scope as they relate to that specific marketplace start to change.
Part of what we've been able to do—Chuck might have mentioned this to you when he was travelling—is that we've created what we call “future-proof” technology. It's part of our approach: to create a platform that can accommodate and change easily to meet the requirements or changing environments of a market. That has boded very well for us as a technology company, because it has allowed us to be quite competitive and easily reactive to some of the changes that I think you're alluding to. It gives us a flexible way into those markets in the Mercosur region.
