Mostly, sir, because it takes time to negotiate them. I think Canada has negotiated, on a pretty ambitious scale, FIPAs around the world. There are a number of others currently under negotiation. The United States and Canada have models of these agreements, which they use, but notwithstanding the fact that they take this modular approach, it takes time to negotiate and to understand both sides, and to get input from industries and investors on both sides. So I don't think there are major stumbling blocks to negotiating FIPAs; it just takes time.
You have to remember that some of the smaller countries have limited resources and they may be negotiating with both Canada and the United States, and then with Australia, and then with some European countries, or the EU. So it's a question of resources, more than ability.
