Thank you.
I might add a few points, because I know a little bit about it. I want to ask two questions.
When you go to a smaller pool of suppliers and you push the price down and somebody wins the bid, is there a propensity afterwards for the price to increase when there has to be additional work done, so that the original price does not become the end price? Does that occur?
The other challenge is that the upper echelons often don't listen to what the people who are doing the work are doing. There often is a disconnect between the top and the middle. Do you have any comments on how to remedy that particular point, and on the first point, is that occurring within your industry with some contracts?
