We did more than that. We conducted visits, which lasted more than 30 seconds. We did not just show up to ask whether they had a program, then only to leave and thank them. We sat down with them to look closely at what they do and how they do it. We put our own services and the services of other people who can help us at our tenants' disposal. Then, we took measures regarding the means in place. We have a contractual relationship with the tenants.
Earlier, you asked whether tenants were serious about security. Most of our tenants have a very keen interest in security, because we implement measures for them. They are the ones who are responsible for the flights and who would be exposed to risk. So they are very concerned about security, and take measures to guard against the risks.
