Okay. Les, this is Chip. Well, let me start in the U.S. because in the U.S., we have both federal incentives, and then there's each state has their own -- and it literally is a portfolio because it might -- there's all kinds of different things that they do from property tax to this, that and the others. At the federal level, that program goes through 2016, and that's an investment tax credit worth 30%. So assuming you're a utility that's a non-cooperative, you can monetize that. And obviously, our customers can monetize that, assuming that they have a tax appetite. But there's also people out there willing to finance these projects that obviously can monetize that federal tax credit. At the state level, there's more -- there are different forms, but those -- there's frankly, when you dig around a little bit, particularly and probably in a couple of states out West and certainly, 3 or 4 states in the East, those incentives exist when you're talking to the right people sometimes. In Europe, there's -- frankly, there's money around. Our pitch has been, it's not about spending more money, it's just figuring out how to spend your money wisely. So we're finding opportunities that if we can deliver on our commitments, which we're comfortable are, we can find the ways to move things forward. Now having said that, we don't want to be sitting here -- our goal is to be able to have our products stand on its own, without incentives. So that's a function of continuing to focus on, as Mike said, the cost reductions of the product and overhead leverage and things like that. So we're still on the track, but, at the same time, there's enough money around to do a bunch of projects.
