The department identified their need to audit each of the 31 federal railway companies over a three-year time period. What we identified was that in that time period they were able to do only 26%, and even of the 26% of audits they completed, we found there were weaknesses in how the audits were completed.
Their plan—and I think that's the important point, that it's their plan, that it's what they have said they need to do to have adequate assurance that the safety management systems of the railway companies are in place—is to be able to do the audits of all 31 of those companies over a three-year time period. They haven't been able to do that, so the end result is that they can't have enough information to make sure the safety management systems are in place as they're supposed to be.
