Maybe I'll start with that and then ask Mr. Bourdon to amplify.
We have taken that recommendation very seriously. It's an important and good thought, in terms of how we look at the balance that's appropriate between audits of safety management systems and other types of inspections, of which we have a whole array in rail, as well.
The issue is to look at what kind of cross-validation is appropriate and what measure of safety issues that would drive, perhaps in bridge inspections having more inspections as well as audits, and perhaps less in another area. But that's something...a significant amount of work is being done on a scientific basis. Contracts have been let, and people are involved in bringing together the statistical validity of numbers of inspections, along with the risk areas, and bringing together the experience of the people in the field who have been doing this for a long time.
We will be ending up with some recommendations fairly soon.
Luc, do you have any specifics? Do we have a timeline for the next stage of that?
