Okay, I actually had two, but maybe I will ask one in a general sort of way.
Obviously, there are regulations to conduct the operations, but on top of those you have the safety management system. In my understanding of it, it's something additional that required a period of maturation and a culture to develop to eventually come into implementation, where you can actually see results.
Where are we in that continuum, when you're looking at the safety management systems and the regulations you've put in place?
