Yes.
Going further, when you answered the question, you talked about SMS being so critical and important at the management level. Last week I had a tour of one of the major rail facilities with the president of the company, and also the president of the union. Actually, what I saw at that particular time was a real pervasiveness right across the structure into the safety management system. The workers also have been very much involved in it and its being important.
Can you comment on how important it is? It's important for management to have this buy-in and to be involved, but could you comment on how important it is from a worker's aspect, because the culture, if it doesn't get down to the people at the ground level, doesn't really adequately suffice, right?
