Thank you. Our next question comes from the line of Sven Eenmaa from Stifel.
Sven Eenmaa - Stifel, Nicolaus & Co., Inc.: Yes. Hi. Thanks for taking my question. Couple of follow-ups on the page 8 table here. So in terms of the pipeline you disclosed, how much of that you would classify as late stage which means, 50%, 60% or a higher probability of receiving an order in late 2015 or in 2016?
Arthur A. Bottone - President, Chief Executive Officer & Director: Good morning. This is Chip, I'll answer that. Again, this is just – this is not the complete list. So there's a lot of other element to this. But when you look at that, I would say that you got 50% of that is pretty late stages stuff. When I say late stuff, it's late stage, that may either – we're talking to people specifically after all of the project development process has done, meaning, we talked about site control and things like that or there's active RFPs on the street, so it's least 50% of that list.
Sven Eenmaa - Stifel, Nicolaus & Co., Inc.: Got it. And in terms of the current demand of PPAs you have signed, could you just give us an overview like how many megawatts you currently have signed up?
Arthur A. Bottone - President, Chief Executive Officer & Director: Well, so PPAs are typically signed by ourselves or whoever the owner of the facility might be. So, for example, in the case of Bridgeport fuel cell park, we set-up a separate LLC that we ultimately sold to Dominion, so that was a PPA that was signed that obviously turned into a project. So I'm not quite sure how to answer the questions on number of PPAs. How many we have out there, I don't know. There is – it's really, I probably know more than megawatts than number of PPAs. But the way this typically works is, as Mike said, with UCI Medical, that was another PPA, and that particular one has not been sold to an investor at this point. But typically, today, these things start with the lease or a PPA. That's kind of the structure and what you see there on that list kind of represents most of that.
Sven Eenmaa - Stifel, Nicolaus & Co., Inc.: That's helpful. In terms of NRG, I mean you have now dropped down one project there. Are you at the stage now where you have like a complete set of standardized documentation, which would allow you to kind of streamline the process going forward or was that more of like a one-off transaction here?
