Before we sign any of those agreements, there is a review.
With regard to the case in point, the one we're working on with Brazil right now, it involved a team going to evaluate their systems and processes to see if they are sufficiently equivalent. However, it's not just that; it's also experience. It would be very unusual for us to establish a full BASA, bilateral aviation safety agreement, with a country that had just come to the table and had not been in the business of producing that product type for some time.
It takes time and experience to learn how to build aircraft, design aircraft, and also, from the authority's perspective, to certify them. That is why we are deliberately cautious in entering into agreements with some of the newer players. They have to build that experience to establish their credibility to a certain extent.
