Thank you very much. Thank you, Mr. Mueller.
That concludes our first round of questioning. We will have time for each party to have one more round of questioning, but I'd ask you to expand on two items just before we move on.
First of all, do you know of any studies, or is there any documentation, on the secondary or beneficial byproducts of energy retrofitting in terms of better indoor ambient air quality, productivity, or fewer person days lost due to illness, etc.? Do any of you know of any evidence that might make the case for a healthy building resulting in a more productive or healthier workforce?
Secondly, I think, Mr. Mueller, you made reference to financing, and so did you, Mr. Seymour. Are some of the energy services contractors self-financing, and if they aren't, are they seeking external venture capital to get these ventures under way? Pension funds seem to me a really good source of capital as a safe investment. Can you tell me roughly the cost of borrowing for this type of venture or the rate of return expected from, for instance, the teachers' pension plan when they put forward the money to undertake this kind of thing?
Is there a brief response on either of those two things before we go to the next round of questioning?
