Each mode is a bit different in terms of the requirements.
If we look at the major companies—the major railway companies and the major air companies—by and large, they have the proper infrastructure and support. They have fairly mature safety management systems, which their regulator oversees to ensure that they're compliant with the regulations and also effective at doing what they're doing.
The issue for us is often with the smaller operators on the railway side, on the marine side, and in the air. In the air and marine modes, they're not required to have safety management systems. Many of them may thus take the approach of just minimal compliance with regulations, which isn't in and of itself enough to effectively manage the risks in their operations.
