When you say “an industry standard”, I expect that there would be an insurance industry standard about how they advise on liability, and they do that with actuarial assessments. Our work was based on risk assessments, I expect in the same manner; I can't confirm that because I don't know exactly what the railways do or what insurance companies do. But we believe the methodology we used has provided for the amount of liability insurance that would cover the accidents that could potentially occur.
