Your question is somewhat multi-pronged. I'll deal with part of it and then ask my colleagues to weigh in.
In terms of some of the other agreements that we have done, particularly most recently, I think it's important to keep in mind that the EFTA and the Peru deals, which are the two that have just come into effect, have not even been in effect a year yet. I think it's too early to make a judgment on their impact in terms of real numbers, because we haven't even got a full year's statistics yet.
In addition, you're looking at numbers during one of the most difficult economic periods of the last century. There can be all sorts of reasons for numbers to go in any direction.
In terms of Costa Rica, frankly, I don't know. Our job is to build an architecture to try to improve opportunities for Canadian business. We cannot force Canadian business to take advantage of what may or may not be there. So I can't make a judgment as to why Costa Rica is or isn't....
Let me speak to Carol, because she is closer to this particular deal. She can identify some of the specifics as to where we think this will be of benefit to us.
