Yes, we use the same elasticity, because there is not much available data on demand elasticity for these types of goods. They are not particularly popular. There are not a lot of international studies, or at least studies for markets comparable to Canada's. The elasticity we used, if I recall correctly, is based on an American study that was done in recent years. Elasticity was therefore estimated to be -2.4 and I believe that was based on luxury vehicles. I'm trying to see in my notes whether that's really it, but I believe it is. We didn't use separate elasticity for vessels, vehicles and aircraft. We used the same figure, which, as you mentioned, is a source of uncertainty.
