Yes, the original recommendation was to clarify roles and responsibilities. That was looked at as requiring an update of MOUs and wouldn't take an awful lot of time. As we looked more closely at the way the system was being managed and the way we were using our transportation of dangerous goods inspectors, it was clear that it would be more effective to combine the transportation of dangerous goods group in one group and have better coordination of their connections with the UN regulations and the evolving priorities.
The decision was made to delay to allow us to integrate the groups. Then, of course, an MOU is still required to look at how civil aviation interacts with transportation of dangerous goods. That has been completed now.
