You're a little over your time, but thank you very much.
That concludes our first round of questioning.
In the meantime, if you don't mind my taking a minute for one question....
Generally, in the industry—this is why we asked you here, and it's not necessarily to find out the efficacy of what you're doing, but more about the industry—what is an acceptable profit margin? What is the markup? If a bridge costs $100 million to build and maintain over 25 years, it's not charity; you're not doing it out of the goodness of your heart. You're trying to make money on it. So how much more do we pay for having somebody else do it than the real cost of the project?
