It's amazing. Even when you negotiate with a small country, you think it is going to be pretty smooth, and there's always something that comes up. Every country is very proud and usually wants to put its stamp on the agreement. The number of issues we have to deal with can vary quite a bit. It very much depends on the particular situation.
There are countries, as I said before, where the doing business environment is challenging for carriers. That is something that can cause us some headaches. Sometimes even with our largest partners we have issues to resolve. It depends very much on the case at hand.
