I'll let Mélinda Nycholat come in as well, because procurement achieves the security requirements for a project that National Defence dictates. One of the things we require from our clients is a clear statement on the security requirements. We put into effect, through the contracting process, the clearance requirements for contractors, individual employees, and so on. The levels do vary. You want the security requirements to be as low as possible, because they add to costs and delays in delivering a project. Once they're defined, then we make sure that all the proper clearances are obtained.
Is that the area that you're looking for an answer on?
