I think we progressed by adopting many of the recommendations that were generated by the report Mr. Watson is talking about. I mentioned earlier that now we have guidelines that were developed to assist the railway. We have best practices that were gathered in two documents to assist the larger railways as well as the smaller operators. We developed a safety culture checklist, as well as other documents, to support SMS.
On a scale of one to five, I'd be very careful about saying where we stand, but we have definitely progressed; there's no doubt about that.
