As you know, we've had the safety management systems within the railways now for a number of years, and there were many concerns that have been raised. I just want to read for the record that the Shareholder Association for Research and Education has cited that the most recent safety figures available show that CN's accident ratio for the second quarter of 2006 increased by 56% over the second quarter of 2005, and for the third quarter of 2006 the accident ratio, again for CN, increased by 40% over the third quarter of 2005. So in a sense we have a problem that is escalating and getting worse.
What's your evaluation of how safety management systems have worked within the railway industry?
