It's mainly because, I guess, we don't agree on what that standard could be. There's been discussion, as we do have a committee that looks at harmonization between the two regulatory regimes. And as you mentioned, in the rail industry, the FRA calculates a tab based on a monetary threshold. As long as you're above that threshold, it becomes a reportable accident.
I don't believe the reporting of accidents should be based on a threshold, but rather on the accident or circumstances that led to an accident or incident. That's why, when you compare the ratio in the States with the one here, you're not comparing apples with apples.
