As I mentioned in my opening remarks, four other container spills that we're aware of were reported to TSB in the last 10 years. All of these occurrences are assessed and it's determined what level of investigation is going to be done. We collect some data and then we archive that. We report on it in our statistics that we report on monthly and then again annually.
In this case, the initiating factor for the investigation of the Zim Kingston was the fire. However, of course we'll look at the preceding factors that led to the fire. As I indicated, one of those was the ignition of dangerous goods that were in some of those containers.
