That's actually part of our watch-list issue, which is multi-modal. That is, all operators should be required to have formal safety management processes, and the regulator has to have a balanced approach to safety. If you see safety management on a continuum, there are some operators who may just have the minimum necessary to meet regulations, and there are others who are very proactive. The system of regulatory oversight has to take into consideration that spectrum of operators, and maybe focus more on inspections for compliance for those operators who have demonstrated that they're not capable of, or are not as effective at, managing their risks, and more audits for those who have demonstrated that they have a mature safety management system.
Absolutely, there has to be a balance between inspections and audits. We've seen definite evidence that it's not there in all modes.
