With respect to lithium batteries, they can be included in things you carry in your checked baggage, or they could be articles that are put in the cargo hold of an aircraft. It could be both scenarios.
The lithium batteries are considered dangerous substances. We are a member of the International Civil Aviation Organization, which is the UN agency that is situated in Montreal. We work together with other countries to determine what can and should go on aircraft that doesn't pose a hazard to the aircraft, the occupants of the aircraft, and the other cargo on the aircraft.
There have been ongoing discussions about that. Actually, I believe it was last week that ICAO determined that they should not be allowed to go on aircraft. Our regulations will not allow that as well. We are in the process now of considering the ICAO decision, and we will comply with that requirement.
