I will just elaborate on one point that Randal made, and then I'll move on to the next question.
A lot of people look at buildings as being static entities, where a guy with a broom comes at the end of the day, and that's the maintenance it requires. In fact buildings—and I highly suspect this is one of them, since I lived in Ottawa for many years when this building was being renovated, and I'm astounded at how well it came out—are complex machines. They are driven by IT increasingly. There are environmental factors that the building operator shapes much more than the designer or the architect, the construction firm and so forth. A lot of what we do is to try to focus on educating and bringing up the skills of the operators, the trades and the professionals who run the buildings day to day. The temptation often is to look at the newest technology, that ground-breaking innovation, or even just the new build as being newer and better. That's human nature. However, in fact—and I may get back to this, time permitting—investing in people, irrespective of the beauty, the age, the stage, the size, the location of the building is very often the best way to drive performance.
