Yes, and that same preparer push, auditor pull happens when they look at any of the values of the capital assets on the government's books. Right now all we require for heritage assets is that you have a record of them so you know you have them. Somebody knows they're there. Obviously there are going to be maintenance records as well, and that's as far as we go, because, as Ron said, we have not cracked that nut. We don't really know how to portray them.
Some people say those assets have economic benefits attributed to them because they bring tourists in, and suggest we should perhaps try to put those benefits in with the value. Trying to do that gets extremely messy and nebulous. It's definitely an area that we haven't resolved, and, as Ron said, it's an even bigger issue for the older European countries.
I'm sorry I can't provide anything definitive. I wish I could.
