I think it's something that would be very relevant. It would be another way in which we could identify whether or not the safety management system employed and utilized by the railways is effective.
To me, it looks like it is effective. Given the general understanding that there has been an increase in volume and traffic and the total number of accidents has been going down, I would suggest to you that something that the railways are doing is effective. It would be nice to know what that is. We would see it clearly if we were able to identify the percentage or a ratio.
