In response to your last question, Mr. Chairman, I would say that we have various measures and various ways in which we come into contact with the industry. I think we have described the various inspection processes that we are responsible for. We undertake assessments. We undertake program validation inspections. We do sampling. We do process inspections.
It also means, in keeping a risk profile up to date, that you have to establish some sort of a relationship. You have to have some knowledge of the carriers you're working with. That basically means that inspectors do have to have visits and know the sector that they're dealing with. There are different ranges in the contact we have with and the knowledge we have of various carriers, which is very important in terms of being able to contribute to our risk profiling of companies. I think that certainly all of those elements are there and are part of how we manage the system.
In terms of the evolution of the system since the 1990s, which was your first question, I think that the safety track record speaks very much to the extent to which the system is very safe. Also, the safety management systems is a very proactive systems-based approach that isn't just focused on an inspector going in and finding a problem but rather on putting the onus on the industry.
