I guess the most obvious is that when NRU was built, which is 50 years ago now, the expectation of revenue wasn't there. It was an investment in the future, and the possibilities were then built on as they came along. All of the new stuff that happened in the 50 years that it's been in existence and in operation is stuff that appeared and we were able to do because of the innovative design and the vision of the people who put it together.
So we can project, but as I try to say in my brief, it's very difficult to predict the future when you actually don't even know where you're starting. None of the things that have been done in NRU were planned when NRU was built. They all were enabled by its existence, so projecting what we're going to do when we do something new is really very difficult.
