I will take that if you'll allow me, Mr. Bigras.
It is a market for carbon, and it's a market of ideas, and it's a market of products. There are a number of exchanges in Europe--I think six or seven, we lost track--and most of them are our members who offer this service, and various companies are members. The European Climate Exchange, which is related to the Montreal Climate Exchange, is the predominant exchange at this point, but there are others.
At some point in this market, there is going to be a rationalization, and there will be a limited number of players. There will continue to be over-the-counter trading and slowly they will be moving to a model with some over-the-counter trading and some exchange trading. That is a typical model that happens in any commodity.
It is normal that at this stage you see a lot of people getting into the market, and over time you will see a rationalization and probably one or two of these exchanges surviving. I wouldn't want to even speculate as to which ones out of them. Indeed, it is a large number, but it's a normal phenomenon at this stage of the market.
