Yes. First of all, we would, as we introduce a regulation....
Many companies, out of good management practice, have safety management systems on their own.
When we introduce a regulation, we require all operators subject to that regulation to submit to us their safety management plan. The first one they develop we review with them and ensure that all the required elements are there. Depending on the regulation, that would be a requirement for their getting an operating certificate as a transportation company. Once we approve it, we regularly audit it.
