In the U.S., all the screeners are TSA employees. It does a couple of things. It allows them to be more flexible in moving people around from area to area if they need to search, because it's one workforce. It also provides a career path for those screeners to see themselves moving somewhere else, which is one of the issues that we see with the CATSA model: these people are brought in through entry-level positions and essentially do not have a career progression within their company. That's it and that's all. They can get to be a point leader at the screening point, but that's as far as they can go. With the TSA model, you are in the TSA, and it does provide further progression.
On the international front, there's a combination. Some of the services are contracted out and some of them are employees. I'm not aware of another that is entirely contracted out.
