I have a quick point on the concept of whether entities have become self regulating. I want to assure you, Madam Chair, and committee members, that is the farthest from the case in our system now. We have more than 10,000 types of activities going on that touch the companies.
The safety management system, for example, requires that they follow prescriptive and additional regulations on safety management systems. We also carry on oversight. We carry on planned oversight, and reactive oversight, where we see there's a problem, and we do follow-up oversight wherever we see there's any problem with any member of the industry. We have the evidence over the last year or two, particularly in cases where we have suspended certificates, of all categories of organizations.
I wanted to reassure everyone on the committee of that.
