I think the particular example that is easiest to refer to is the safety management system example. It was identified in 1999 that they needed to make a change from a system based on inspections to a system based on audits.
The actual regulatory framework was put in place in 2001. We did the audit in 2013 and still found the significant weaknesses that we've identified here. I think that alone speaks to the length of time.
When you add to that the fact that they are going to have more companies to have to oversee, and the fact that they still aren't where they need to be right now, it makes you wonder how much longer it's going to take to complete the work.
