If I may, we're both extremely cautious and realistic in the appreciation of the long-term requirement for land. In past years we've been a little too quick sometimes to divest land. In some cases we've had to actually go back and try to re-acquire some land that we divested.
To Mr. Pitfield's answer, we do have a process. It's part of a robust, long-term capability planning process which typically uses a 20-year planning horizon. The real property component of that is integrated into those discussions. That's the kind of cycle you're seeing. Many of the divestments that are reflected in the supps now are indicative of decisions, or at least advice, around the divestment of property which predates many, if not all of us, sitting at the table today.
