There is still an outstanding matter, which we reported on at the beginning of our audit, relating to the security requirements around Centre Block. Obviously, there are a lot of factors that go into considering what's supposed to happen for security, and a lot of partners to work with. As those decisions take time, though, it puts pressure on other elements of the project, including construction. If changes are made after construction has started, the costs and schedule impacts can be pretty significant.
